Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
Example one
As shown in fig. 1, the present embodiment provides a wire harness installation apparatus, which includes a fastening member 1, a pipe clamp 3 disposed on the fastening member 1 and used for a wire harness to pass through, and an adjusting pad block 2 disposed on the fastening member 1 and adjacent to the pipe clamp 3, where at least one pipe clamp 3 is disposed.
In the present embodiment, as shown in fig. 1, the fastener 1 is a T-bolt. The fastener 1 is installed on the vehicle body of the rail transit vehicle, a T-shaped groove is formed in the vehicle body, and the head of the fastener 1 is embedded into the T-shaped groove formed in the vehicle body. The pipe clamp 3 is a P-shaped pipe clamp, the locking nut 4 is arranged on the fastening piece 1, the pipe clamp 3 is arranged between the adjusting cushion block 2 and the locking nut 4, a wiring harness needing to be installed can penetrate through a hole of the pipe clamp 3, and the wiring harness is clamped by the pipe clamp 3, so that the fixed installation of the wiring harness is realized.
When the binding tape is used, the corresponding P-shaped pipe clamp is selected according to the outer diameter of the wire harness, and the wire harness can be more reliably fixed by adopting a mode of matching the bolt and the P-shaped pipe clamp relative to the binding tape; when the wire harness turns around, the routing direction of the wire harness can be realized by adjusting the direction of the P-type clamp according to the routing direction of the wire harness, as shown in fig. 4.
As shown in fig. 1, an adjusting cushion block 2 is arranged on a fastening member 1, the adjusting cushion block 2 is a cylinder with openings at both ends and a hollow interior, and the fastening member 1 and the adjusting cushion block 2 are coaxially arranged. The adjusting cushion block 2 is made of metal. A gasket is arranged between one end of the adjusting cushion block 2 and the vehicle body, and another gasket is arranged between the other end of the adjusting cushion block 2 and the pipe clamp 3. The locking nut 4 is in threaded connection with the fastener 1, and after the locking nut 4 is screwed down, the pipe clamp 3 and a washer can be clamped between the locking nut 4 and the adjusting cushion block 2, so that the pipe clamp 3 can clamp a wire harness.
The wire harness installation device with the structure can be realized only by using the common fastener 1, the common P-shaped clamp and the common adjusting cushion block 2, and compared with the traditional metal layered bracket, the wire harness installation device saves materials, complex processing, customized requirements and the like, and reduces the cost. The rail transit vehicle has higher requirement on weight, and the wire harness installation device adopting the structure can replace the traditional metal bracket to reduce the weight of the vehicle.
