During use, the test stand and the measurement and control cabinet (a key component for monitoring and control) are located in a test room and a measurement and control room, respectively, separated by a partition wall. A large number of cables from the measurement and control cabinet extend through a trench (located at the bottom of the partition wall between the two rooms) into the test room, where they are connected to one side of a terminal block. Detachable test leads extend from the other side of the terminal block, extending upward along the side of the test stand before connecting to corresponding wiring connections at the top of the stand.
[0004] The test bench has the following shortcomings during operation: 1. The cables entering the test room through the trench are scattered on the ground, which is not only unsightly but also difficult to clean and maintain; 2. The test lines leading out from the terminal block extend upward along the side facade of the test bench, making the wiring on the side facade and work surface of the test bench messy, which is not only unsightly but also difficult to clean and maintain; 3. Unused test lines should be removed and properly stored, but there is currently no fixed storage location for the test lines. It is not suitable to place them on the ground or on the work surface of the test bench, which is not only unsightly but also difficult to clean and maintain. Utility Model Content

DETAILED DESCRIPTION
[0024] like Figure 1-5 As shown, a special gantry for vertical cable laying includes a column 1, a beam 2, a horizontal rotation device, a lifting drive device and a terminal board 5.
[0025] The column 1 is installed on the ground by horizontal rotation through a horizontal rotation device and is arranged vertically. A vertically extending wiring cavity A11 is provided inside the column 1. The lower end and the upper end of the side wall of the column 1 are respectively provided with a wire inlet A12 and a wire outlet 13 connected to the wiring cavity A11. An inspection port A16 is provided in the upper middle part of the side wall of the column 1.
[0026] A horizontally extending wiring cavity B21 is provided within the crossbeam 2. A wire entry port B22 is provided on the rear end surface of the crossbeam 2. A wire hanging rod 23 is connected to the lower front surface of the crossbeam 2. An inspection port B24 is provided on the upper surface of the crossbeam 2. Mounting ports 25 are provided on both side elevations of the crossbeam 2. The crossbeam 2 is movably mounted on the upper end of the side wall of the column 1 via a lifting drive. Driven by the lifting drive, the crossbeam 2 moves up and down along the side wall of the column 1. During this movement, the wire entry port B22 of the crossbeam 2 and the wire exit port 13 of the column 1 are always arranged in a diametrically opposed relationship, ensuring that the wiring cavity B21 of the crossbeam 2 and the wiring cavity A11 of the column 1 are always connected.
[0027] The terminal block 5 is removably mounted on the mounting opening 25 of the beam 2. The side of the terminal block 5 facing the wiring cavity B21 of the beam 2 is used for flexible connection of cable ends (located in the wiring cavity B of the beam). The side of the terminal block 5 facing the outside of the beam 2 is used for flexible connection of various test lines.
[0028] Preferably, the horizontal rotation device includes a chassis 31, a slewing bearing 32, a stopper 33, a stopper 34, a wrench device 35 and a locking device 36. The chassis 31 is fixedly mounted on the ground by bolts. The inner ring of the slewing bearing 32 is fixedly mounted on the chassis 31, and the outer ring of the slewing bearing 32 is fixedly connected to the lower end face of the column 1. There are two stoppers 33, and the two stoppers 33 are respectively mounted on the chassis 31 and distributed on both sides of the slewing bearing 32. The stopper 34 is fixedly mounted on the lower end of the column 1. When the column 1 and the stopper 34 rotate clockwise or counterclockwise together, they will respectively abut against the two stoppers 33 when the rotation reaches the limit position, that is, the stopper 34 and the two stoppers 33 jointly limit the rotation angle range of the column to 180°. The wrench device 35 includes a handle 351 and a handle base 352. The handle 351 is hinged to the handle base 352 and rotates in a vertical plane along the hinge axis. When no external force is applied to the handle 351, it naturally hangs down and is parallel to the column 1. The locking device 36 is installed between the chassis 31 and the outer ring of the slewing bearing 32. It is used to lock or unlock the outer ring of the slewing bearing 32, thereby switching the column 1 between the two states of rotation and locking.
[0029] Preferably, the locking device 36 includes a pressure block 361 and a handle 362. The pressure block 361 is associated with the handle 362 and moves horizontally and linearly when the handle 362 rotates, thereby pressing or releasing the outer ring of the slewing bearing 32. When the pressure block 361 presses the outer ring of the slewing bearing 32, the outer ring of the slewing bearing 32 cannot rotate, even if the column 1 is locked. When the pressure block 361 releases the outer ring of the slewing bearing 32, the outer ring of the slewing bearing 32 can rotate.
[0030] Preferably, the inspection opening A16 of the column 1 and the inspection opening B24 of the beam 2 are respectively detachably mounted with cover plates (omitted and not shown in the figure).
[0031] Preferably, a hollow opening 14 is provided at the upper end of the side wall of the column 1, arranged opposite the wire outlet 13. The lifting drive device includes an electric push rod 41, an ear seat 42, a slide 43, and a slider 44. The electric push rod 41 includes a main body and a telescopic rod. The main body of the electric push rod 41 is hinged to the upper end of the side wall of the column 1. The ear seat 42 is located in the wiring cavity A11 of the column 1. The front end of the ear seat 42 extends from the wire outlet 13 of the column 1, and the rear end of the ear seat 42 extends from the hollow opening of the column 1. The rear end of the ear seat 42 is hinged to the telescopic rod of the electric push rod 41, and the front end of the ear seat 42 is fixedly connected to the rear end face of the crossbeam 2. The slide 43 is fixedly mounted on the upper end of the side wall of the column 1. The slider 44 is fixedly mounted on the rear end face of the crossbeam 2 and slides in engagement with the slide 43. When the telescopic rod of the electric push rod 41 is extended or retracted, the crossbeam 2 is lifted and lowered along the column 1 through the sliding engagement of the slider 44 and the slide 43.
[0032] Preferably, the connection between the front end of the ear seat 42 and the rear end face of the crossbeam 2 is located at the upper end of the wire inlet B22. There are two chutes 43 and two sliders 44, respectively. The two chutes 43 are distributed on both sides of the wire outlet 13 of the column 1, and the two sliders 44 are distributed on both sides of the wire inlet B22 of the crossbeam 2.
[0033] Preferably, a plurality of fixed lines 15 are welded in the wiring cavity A11 of the column 1, all of the fixed lines 15 are arranged in parallel and consistent with the length direction of the column 1, and a plurality of threading holes are provided on the fixed lines 15 at intervals along the length direction, and the threading holes are for binding straps or cables to pass through (the cables are tied to the fixed lines 15 by passing the binding straps through the threading holes).
[0034] Preferably, a plurality of U-shaped hooks 231 are fixedly connected to the wire hanging rod 23, and all the U-shaped hooks 231 are arranged in a row at intervals to form a U-shaped groove for hanging multiple test wires.
[0035] Preferably, limit blocks 45 are fixedly installed at both the upper and lower ends of the slide groove 43 to prevent the slider 44 from escaping from the upper end or the lower end of the slide groove 43.
[0036] Briefly describe the use of this utility model:
[0037] A dedicated gantry for hanging cable routing is used to lay the test lines and cables required for test bench operation. After extending from the measurement and control cabinet, the cables pass through the wiring cavity A11 of column 1 and the wiring cavity B21 of beam 2, ultimately connecting to the terminal block 5 mounted on the side of beam 2. Various test lines are connected to the terminal block 5 and then hang down from it to connect to the corresponding sensors or power-requiring components on the test bench.
[0038] Lifting the component under test requires the rotation function of column 1. First, adjust locking device 36 to unlock the outer ring of slewing bearing 32. Grasp handle 351 and lift it to a suitable angle for exerting force. Using handle 351 as the force point, rotate column 1, thereby moving crossbeam 2 out of the area directly above the test stand, facilitating smooth lifting. Once lifting is complete, rotate column 1 back to its original position, allowing crossbeam 2 to return to the area directly above the test stand, facilitating the connection and routing of test cables.
[0039] By controlling the extension or contraction of the telescopic rod of the electric push rod 41, the crossbeam can be controlled to rise or fall along the column 1. When it is lowered to the low position, it is convenient to plug and unplug the test line, and when it is raised to the high position, the test line can be fully extended (to avoid spreading on the working surface of the bench).
