The number of the four-wheel drive synchronous lifting transmission mechanisms is two, which are respectively located on both sides of the load-bearing frame structure. The number of the double-motor synchronous drive mechanisms is two, which are respectively located on both sides inside the walking vehicle frame. The load-bearing frame structure includes concave-shaped columns, diagonal tie rods, stiffening rib plates, wire rope diagonal stay cables, and a transverse beam. The number of the concave-shaped columns is four, which are respectively fixed on the top of the walking vehicle frame. The four concave-shaped columns and the transverse beam enclose the four sides of the load-bearing frame structure.

[0004] For existing lifting trams such as the above, guardrails are provided on the outer side of the operation platform, and L-shaped optoelectronic brackets are often provided on the guardrails. The wire harness is led to the tram through the optoelectronic bracket. In the specific implementation process, the L-shaped optoelectronic bracket is fixedly installed on the outer wall of the guardrail through fasteners, and the external connector is passed through the optoelectronic bracket and then connected to the optoelectronic switch interface on the tram. The optoelectronic bracket can only avoid the drooping at the connection of the optoelectronic switch, and its functionality is relatively single. When the external wire harness is pulled or shaken, the connection of the optoelectronic switch is prone to looseness. Therefore, it is urgent to propose a corresponding optoelectronic bracket for the tram guardrail to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an optoelectronic bracket for a tram guardrail to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An optoelectronic bracket for a tram guardrail includes a support frame. A fixing ring is fixedly installed at the top of the vertical end of the support frame. A telescopic sleeve is fixedly installed on the outer wall of the fixing ring. An installation ring is fixedly installed at the open end of the telescopic sleeve. A screw rod is screwed on the inner wall of the fixing ring. A positioning component for wire harness positioning is arranged between the open end of the screw rod and the fixing ring.

[0008] Preferably, a rotating rod is rotatably connected to the outer surface wall of the fixed ring. A pulling frame is slidably connected to the inner surface wall of the rotating rod, and a spring is fixedly installed between the pulling frame and the inner surface wall of the rotating rod. A coupling part for coupling the pulling frame and the screw rod is provided between the outer surface wall of the pulling frame and the screw rod.

[0009] Preferably, the coupling part includes a rotating block and a closing cover. The closing cover and the rotating block are respectively fixedly connected to the pulling frame and the top of the screw rod, and the closing cover is sleeved on the outer surface wall of the rotating block.

[0010] Preferably, a connecting seat is fixedly installed on the outer surface wall of the arc end of the fixed ring through a screw, and the connecting seat is rotatably connected to the rotating rod through a pin shaft.

[0011] Preferably, the positioning assembly includes a pressing rod. The outer surface wall of the pressing rod is slidably connected to the inner surface wall of the fixed ring, and the top of the pressing rod is rotatably connected to the open end of the screw rod.

[0012] Preferably, the outer surface wall of the pressing rod is slidably connected to the inner surface wall of the fixed ring through a vertically arranged sliding groove, and an elastic cushion layer is fixedly installed at the bottom of the pressing rod.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the support frame is fixed to the outside of the guardrail through fasteners. After the wire harness passes through the fixed ring and the telescopic sleeve, it is connected to the optoelectronic interface on the tram. Then, the telescopic sleeve is pulled, and the mounting ring is fixed to the outside of the optoelectronic interface through fasteners. When the screw rod is rotated, while the screw rod is screwed with the fixed ring, the bottom of the screw rod rotates and cooperates with the top of the pressing rod. At the same time, the outside of the pressing rod is restricted by the sliding groove, so that the pressing rod moves steadily downward until the pressing rod presses the outside of the wire harness, thereby realizing the positioning of the wire harness at this place. At this time, the telescopic sleeve realizes the support and protection of the wire harness. And when the wire harness generates a traction force due to shaking, the traction force will act on the connection between the pressing rod and the wire harness, ensuring the stability of the connection between the wire harness and the optoelectronic interface.

[0015] 2. In this application, after the positioning of the wire harness is completed by the pressing rod, the pulling frame is pulled and the rotating rod is flipped. The pulling frame stretches the spring until the closing cover is pressed against the outside of the rotating block at the top of the screw rod. At this time, the spring provides a vertical binding force for the closing cover through the pulling frame, and the closing cover can limit the axial loosening of the rotating block and the screw rod through friction.

[0025] The support frame 1 is fixed to the outside of the guardrail through fasteners. After the wire harness passes through the fixed ring 2 and the telescopic sleeve 3, it is connected to the optoelectronic interface on the tram. Then, the telescopic sleeve 3 is pulled, and the mounting ring 4 is fixed to the outside of the optoelectronic interface through fasteners. While rotating the screw 5, while the screw 5 is screwed with the fixed ring 2, the bottom of the screw 5 is rotationally matched with the top of the pressure rod 7. At the same time, the outside of the pressure rod 7 is restricted by the chute, so that the pressure rod 7 moves steadily downward until the pressure rod 7 presses the outside of the wire harness, thereby realizing the positioning of the wire harness here. At this time, the telescopic sleeve 3 realizes the support and protection of the wire harness. And when the wire harness generates a traction force due to shaking, the traction force will act on the connection between the pressure rod 7 and the wire harness, ensuring the stability of the connection between the wire harness and the optoelectronic interface.

[0026] Specifically, as Figure 2 And Figure 4As shown, the outer wall of the fixing ring 2 is rotatably connected to a rotating rod 9, the inner wall of the rotating rod 9 is slidably connected to a pulling frame 8, and a spring 11 is fixedly installed between the pulling frame 8 and the inner wall of the rotating rod 9, and a coupling portion for coupling the pulling frame 8 and the screw 5 is provided between the outer wall of the pulling frame 8 and the screw 5, the coupling portion includes a rotating block and a closing cover 10, the closing cover 10 and the rotating block are respectively fixedly connected to the pulling frame 8 and the top of the screw 5, the closing cover 10 is sleeved on the outer wall of the rotating block, after the positioning of the wiring harness is completed by the pressing rod 7, the pulling frame 8 is pulled and the rotating rod 9 is flipped, the pulling frame 8 stretches the spring until the closing cover 10 is pressed to the outside of the rotating block at the top of the screw 5, at this time the spring 11 provides a vertical restraining force for the closing cover 10 through the pulling frame 8, and the closing cover 10 can limit the axial loosening of the rotating block and the screw 5 through friction.

[0027] Specifically, Figure 2 and Figure 3 As shown, the outer wall of the arc-shaped end of the fixing ring 2 is fixed with a connecting seat 12 by screws, and the connecting seat 12 is rotatably connected to the rotating rod 9 through a pin shaft, so as to facilitate the disassembly and assembly of the overall pulling frame 8, the closing cover 10 and the rotating rod 9. The positioning component includes a pressure rod 7, the outer wall of the pressure rod 7 is slidably connected to the inner wall of the fixing ring 2, and the top of the pressure rod 7 is rotatably connected to the open end of the screw rod 5, the outer wall of the pressure rod 7 is slidably connected to the inner wall of the fixing ring 2 through a vertically arranged slide groove 6, and an elastic cushion layer is fixedly installed at the bottom of the pressure rod 7 to avoid direct contact between the pressure rod 7 and the wiring harness and cause damage to the wiring harness. When the screw rod 5 is rotated, the screw 5 is screwed into the fixing ring 2, and the bottom of the screw 5 is rotatably matched with the top of the pressure rod 7.

After the wiring harness passes through the fixing ring 2 and the telescopic sleeve 3, it is connected to the photoelectric interface on the tram. Then the telescopic sleeve 3 is pulled, and the mounting ring 4 is fixed to the outside of the photoelectric interface by fasteners. When the screw rod 5 is turned and the screw rod 5 is screwed together with the fixing ring 2, the bottom of the screw rod 5 rotates and cooperates with the top of the pressure rod 7. At the same time, the outside of the pressure rod 7 is constrained by the slide groove, so that the pressure rod 7 moves downward stably until the pressure rod 7 is pressed against the outside of the wiring harness, so as to realize the positioning of the wiring harness here. The telescopic sleeve 3 supports and protects the wiring harness, and when the wiring harness generates traction due to shaking, the traction will act on the connection between the pressure rod 7 and the wiring harness, ensuring the stability of the connection between the wiring harness and the optoelectronic interface. After the wiring harness is positioned by the pressure rod 7, the pulling frame 8 is pulled and the rotating rod 9 is flipped. The pulling frame 8 stretches the spring until the closing cover 10 is pressed onto the outside of the rotating block at the top of the screw 5. At this time, the spring 11 provides a vertical restraining force for the closing cover 10 through the pulling frame 8. The closing cover 10 can limit the axial loosening of the rotating block and the screw 5 through friction.
