Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.
As shown in fig. 1-4, the roller conveyor transmission chain tensioning device comprises a roller conveyor side plate 1, a movable seat 3 and a unidirectional lifting mechanism 2, wherein the movable seat 3 is arranged on the roller conveyor side plate 1, the unidirectional lifting mechanism 2 which can be adjusted along the vertical position is arranged on the movable seat 3, and the roller position can be changed by adjusting the unidirectional lifting mechanism 2, so that tensioning or loosening maintenance is carried out on the chain transmission mechanism.
The roller conveyor is characterized in that a large guide sleeve 18 is arranged on the roller conveyor side plate 1, the large guide sleeve 18 is adjustable along the vertical position of the roller conveyor side plate 1, the movable seat 3 is slidably connected to the large guide sleeve 18, and a large spring 4 is arranged between the movable seat 3 and the large guide sleeve 18. In this embodiment, the big uide bushing 18 still includes uide bushing base 17, and uide bushing base 17 still is provided with kicking block 19, equipartition waist hole on the uide bushing base 17 of big uide bushing 18, waist hole position passes through the mounting bolt to be fixed on roller conveyer curb plate 1, when needing to adjust big uide bushing 18 position, loosens the bolt on the uide bushing base 17, and the adjusting bolt 8 that is used for lifting big uide bushing 18 is installed along vertical position on the roller conveyer curb plate 1, in this embodiment, installs fixed regulating block 7 on the roller conveyer curb plate 1, and adjusting bolt 8 installs in fixed regulating block 7 position to correspond kicking block 19 position, after loosening the bolt on the uide bushing base 17, adjusting bolt 8 removes the back, can jack block 19 to jack up or descend (because big uide bushing 18 self dead weight can descend).
The unidirectional lifting mechanism 2 comprises a roller 9, a lifting bar 11, a small guide sleeve 12, a small spring 13 and a movable clamping tongue 14, wherein the small guide sleeve 12 is installed on the movable seat 3, the lifting bar 11 is connected in a sliding manner in the small guide sleeve 12, the roller 9 is installed on the lifting bar 11, in the embodiment, a bolt can be used as a rotating shaft, after the roller 9 is installed, the tail end of the bolt is fixed by adopting the bolt 10, clamping teeth are uniformly distributed on the lifting bar 11, through holes penetrating through the small guide sleeve 12 are transversely formed in the edge, a movable clamping tongue 14 for clamping the clamping teeth is installed on the through holes, the small spring 13 is sleeved on the movable clamping tongue 14, a restoring force is always generated, the clamping teeth which push the movable clamping tongue 14 to the position of the lifting bar 11 are clamped, in the embodiment, any clamping tooth on the lifting bar 11 is inclined downwards, namely, the clamping tooth is in a right triangle, the upper side is inclined by 45 degrees, and the lower side is horizontal. Correspondingly, the lower side of the head of the movable clamping tongue 14 is inclined by 45 degrees, and the upper side is horizontal and can be meshed with the clamping teeth. When the lifting strip 11 moves upwards, the lifting strip 11 is directly pushed upwards, the clamping direction is downward, and when the lifting strip 11 is pushed upwards, the lifting strip 11 overcomes the restoring force of the small spring 13, the lifting strip 11 is required to move downwards, the movable clamping tongue 14 is pulled to move backwards, the restoring force of the small spring 13 is overcome, and the movable clamping tongue 14 releases the clamping teeth, so that the lifting strip 11 can be moved downwards.

The fixed adjusting block 7 arranged on the roller conveyor side plate 1 is utilized to tightly press or loosen the upper jacking block 19 of the guide frame 5 through the adjusting bolt 8, so that the guide frame 5 can move up and down. The guide base 5 drives the movable base 3 to ascend or descend by means of the force applied by the large spring 4. Because the spring has certain elastic force, the spring can play a role in buffering related parts on the movable seat 3, and the impact force of the transmission chain on the unidirectional tensioning mechanism is relieved. When the transmission chain is tensioned, the movable seat 3 rises to drive the roller 9 of the unidirectional tensioning mechanism to tightly prop up the transmission chain, thus completing rough adjustment work. And then according to the tightness degree of each group of transmission chains, the corresponding unidirectional tensioning mechanisms are utilized to realize rapid lifting adjustment, the roller 9 on each group of unidirectional tensioning mechanisms is ensured to be stressed consistently with the transmission chains, and finally the fine adjustment work is completed. The lifting strip 11 of the unidirectional tensioning mechanism is provided with an oblique tooth slot, a movable clamping tongue 14 and a small spring 13 to realize unidirectional movement self-locking function and prevent the lifting strip 11 from falling under force. When a certain group of transmission chains are in use and are in problem, the transmission chains are required to be replaced, the corresponding one-way tensioning mechanism movable clamping tongues 14 are pulled out of the inclined tooth grooves of the lifting strips 11, the lifting strips 11 are put down, the transmission chains can be loosened, the replacement of damaged transmission chains is completed, and then the lifting strips 11 are quickly moved upwards by hands, so that the tensioning work of the new transmission chains is completed.
The invention can buffer the roller, relieve the impact force of the transmission chain on the unidirectional lifting mechanism, realize rapid lifting adjustment by utilizing the corresponding unidirectional lifting mechanism according to the tightness degree of the transmission chain, ensure that the unidirectional lifting mechanism is consistent with the stress of the transmission chain, release the roller by adjusting the unidirectional lifting mechanism, facilitate maintenance, avoid the phenomena of tooth jump and blockage of the transmission chain, indirectly cause the abnormal abrasion of the chain wheel and the bearing, and ensure the running stability of equipment.
