Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the electric retractor.
Detailed Description
The invention is specifically described below with reference to the accompanying drawings, as shown in the figures, the invention includes two measuring arms, namely a measuring arm 201 and a measuring arm 202, which are coupled to each other through a rotating shaft I3, the lower ends of the measuring arms 201 and 205 are abutted to the vertical roll 1 to be measured, the upper end of the measuring arm 201 is provided with a handle 10 and an electric contraction device, the upper end of the measuring arm 202 is provided with a clamping groove 7 coupled to the upper end of the measuring arm, and the clamping groove 7 is coupled to the measuring arm 202 through a rotating shaft II 6; the measuring scale 5 penetrates through the clamping groove 7, and the rear end of the measuring scale 5 is in shaft connection with the upper end of the measuring arm I201 through a rotating shaft III 4;
in order to ensure that the two measuring arms can be abutted against the vertical roll during one-hand operation, the lower part of the second measuring arm needs to be lifted, and meanwhile, the lower part of the first measuring arm is abutted against the other vertical roll; the electric contraction device is used for lifting the lower part of the second measuring arm; the electric contraction device comprises a through hole 203 arranged at the lower end of the second measuring arm 202, the lower end of the cable 23 is hung in the through hole 203, and the upper end of the cable is wound on the collecting wheel 11; the collecting wheel is driven by a motor to rotate; the collecting wheel, the motor and the motor battery are all arranged at the tail end of the handle, and a motor switch 9 is arranged in front of the handle;
in order to prevent the motor from being burnt out due to the fact that the motor is locked by external force caused by the fact that the length of the mooring rope is fixed after the second measuring arm is abutted to the vertical roller, a motor protection structure is further arranged; the motor protection structure comprises a driving wheel 12 fixed on an output shaft of a motor, wherein the driving wheel 12 is provided with a first radial blind hole 15, the collecting wheel 11 is provided with a second radial blind hole 20, and an opening of the second radial blind hole 20 is larger than that of the first radial blind hole 15; a first clamping ball 16 is arranged in the first radial blind hole 15, and a first spring 17 is arranged between the lower part of the first clamping ball 16 and the bottom of the first radial blind hole 15; and a first snap ring 22, a second spring 18, a pressing ring 21 and a compression bolt 19 are sequentially arranged in the radial blind hole II 20 from bottom to top, the lower part of the compression bolt 19 is abutted against the pressing ring 21, the upper part of the second spring 18 is abutted against the pressing ring 21, and the lower part of the compression bolt is abutted against the snap ring 22.
When the cable is not locked, the motor has rotating power and can drive the driving wheel to rotate, and at the moment, the clamping ball is sunk into the groove of the radial blind hole II to drive the collecting wheel 11 to rotate; when the cable is locked, the driving wheel rotates and the collecting wheel does not rotate due to the power of the motor, so that the clamping ball rolls out of the groove of the radial blind hole II, and the groove is quickly filled with the clamping ring under the action of the spring II, so that the collecting wheel does not rotate along with the driving wheel; the compression amount of the second spring by the pressing ring can be adjusted by adjusting the screwing depth of the compression bolt, so that the elastic force borne by the clamping ring is adjusted, when the elastic force borne by the clamping ring is greater than the elastic force borne by the first spring by the clamping ball, the collecting wheel does not rotate along with the driving wheel, otherwise, the collecting wheel rotates along with the driving wheel; proper rotation of the compression bolt by the appropriate preload amount ensures that when the cable is locked, the drive wheel rotates and the collection wheel does not rotate.
And the clamping groove is provided with a locking nut for locking the position of the measuring scale.
The invention has the advantages that: due to the utilization of the principle of similar graphs, an operator does not need to go to a position with environmental danger for measurement, but can directly measure through the measuring arm; the electric retractor can ensure that an operator can measure with one hand on one hand and can lock the measuring scale with the other hand, so that the electric retractor is convenient to use; the electric shrinking device is also provided with a protection structure for preventing the motor from being locked by external force and burnt.
