Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for rigid contact networks, and specifically relates to a quick installation structure for a rigid contact network busbar detection device. Background Technology

[0002] Rigid overhead contact lines are a common power supply method used in urban rail transit. They mainly consist of aluminum alloy busbars and contact wires embedded in them. When subway trains are running, power is supplied to the train through the sliding contact between the pantograph and the contact wire. However, as the operating mileage increases, the surface of the contact wire will wear due to friction. When the wear is abnormal, the pantograph-contact contact relationship deteriorates, the pantograph's current collection quality decreases, and the power supply stability decreases. Therefore, operating units need to regularly use specialized testing equipment to inspect the wear condition of the contact wire, promptly detect abnormalities, and arrange maintenance.

[0003] Currently, rigid contact wire inspection equipment generally uses a wheeled walking mechanism and a busbar clamping method for fixation. Existing devices generally have independent disassembly and assembly structures for each wheel pair, requiring operators to use a ladder truck and perform disassembly and assembly operations on each wheel pair one by one at a height. The entire installation process usually requires manual lifting of the equipment, folding the walking wheels one by one to align with the busbar, turning multiple sets of manual knobs or bolts, and then tightening each walking wheel one by one to complete the installation and fixation.

[0004] It is evident that the installation of such testing equipment is cumbersome, often requiring several minutes or even longer to complete the installation of a single testing point. Furthermore, installation often necessitates working at heights, requiring workers to hold the equipment steady with one hand while operating the locking mechanism with the other, repeatedly bending over and lifting, resulting in extremely high labor intensity. Therefore, there is an urgent need for a rapid installation structure for rigid contact wire busbar testing equipment that can solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid installation structure for rigid contact wire busbar inspection equipment, addressing the aforementioned shortcomings and solving the problems of cumbersome and time-consuming installation procedures and high labor intensity for workers in current rigid contact wire inspection equipment. To achieve the above objective, this utility model provides the following technical solution: A rapid installation structure for a rigid contact wire busbar testing device includes a base frame, two sets of traveling mechanisms, and a locking unit; Two sets of traveling mechanisms are arranged opposite each other on the left and right sides above the base frame; each set of traveling mechanisms includes a support plate, a drive assembly, and two traveling components arranged opposite each other on the support plate in the front-to-back direction; each traveling component includes a traveling wheel, a movable bracket, and a guide assembly; the traveling wheel is movably mounted above the movable bracket; the drive assembly is used to drive the traveling wheel to rotate; the movable bracket includes at least a locking link; the guide assembly is vertically mounted on the movable bracket and is used to drive the locking link to move vertically by lifting and lowering. The locking unit includes a knob, a transmission mechanism, and four locking components. The transmission mechanism includes a first connecting rod and two transmission components connected to it. The two transmission components are respectively installed on the inner side of two sets of walking mechanisms. Each transmission component is simultaneously connected to two locking components. The four locking components correspond one-to-one with four locking links. The knob is located on one of the transmission components and is used to drive the two transmission components to move synchronously. When the knob is rotated to the locked position, the locking component locks the vertical movement of the locking link, thereby keeping the walking wheel in the clamped position. When the knob is rotated to the unlocked position, the locking component releases the vertical movement of the locking link, allowing the walking wheel to switch to the released position.

[0006] Furthermore, the guide assembly includes a guide wheel, a guide shaft, a guide spring, and a sliding mounting base; the sliding mounting base is fixedly connected to the middle of the locking link; the guide wheel is located above the guide shaft; the guide shaft is vertically and flexibly mounted on the sliding mounting base; the guide spring is fitted and mounted above the sliding mounting base and sleeved on the outer peripheral wall of the guide shaft.

[0007] Furthermore, the movable support also includes a fixed rod, a first tension spring, and a frame; the lower end of the fixed rod is fixed to the support plate; the frame includes a first connecting part and a second connecting part; the traveling wheel is mounted on the first connecting part; the upper end of the fixed rod and the upper end of the locking link are respectively hinged to two opposite side walls of the second connecting part; the two ends of the first tension spring are respectively connected to the second connecting part and the fixed rod; the lower part of the locking link is provided with a protrusion; when the guide shaft moves downward, it drives the locking link to continue moving downward together by contacting the protrusion; the lower part of the locking link is also provided with a positioning groove.

[0008] Furthermore, the locking assembly includes a mounting base, a ratchet, an adjusting rod, and two second tension springs; the mounting base is mounted on a support plate and located below the guide assembly; the ratchet is movably disposed in the mounting base, and the lower part of the ratchet has a notch for engaging with a positioning slot; the adjusting rod is pivotally disposed on the mounting base and is drively connected to the transmission assembly; both second tension springs are connected between the ratchet and the adjusting rod; the adjusting rod is used to change the tension of the two second tension springs on the ratchet by its own pivoting, so that when the knob is rotated to the locked position, the ratchet tends to pop outward from the mounting base, and when the knob is rotated to the unlocked position, the ratchet tends to retract inward from the mounting base.

[0009] Furthermore, two second tension springs are slidably inserted into the mounting base; the first ends of the two second tension springs are respectively connected to the upper and lower ends of the ratchet, and the second ends of the two second tension springs are simultaneously connected to the upper and lower sides of the adjusting rod; the middle part of the adjusting rod is hinged to the mounting base, and the upper end is connected to the transmission assembly.

[0010] Furthermore, the transmission assembly includes a rotating rod, an end connector passing through the rotating rod, and two transmission wheels; the end connector is located at the front end of the rotating rod; both ends of the first connecting rod are respectively connected to the two end connectors of the two transmission assemblies; the knob is installed on the front side of one of the end connectors and is coaxially arranged with the rotating rod; the transmission wheel is connected to the upper end of the adjusting rod of the corresponding locking assembly.

[0011] Furthermore, a fixed support plate is provided on the front and rear sides of the support plate respectively; the transmission mechanism also includes two T-shaped bushings; each T-shaped bushing is installed and fitted on a fixed support plate; the rotating rod of each transmission component passes through the two T-shaped bushings and is rotatably supported on the two fixed support plates.

[0012] Furthermore, it also includes a ball-head plunger located on the side wall of the support plate near the transmission assembly; the end connector is also provided with a rotating mating plate, and the side wall of the rotating mating plate is provided with two limiting grooves; the ball-head plunger is provided with a ball that is engaged with the limiting groove of the rotating mating plate.

[0013] Furthermore, the drive assembly includes two walking motors; the two walking motors are respectively mounted on two walking wheels in any set of walking mechanisms.

[0014] Furthermore, at least one handle is provided on each of the front and rear side walls of the base frame.

[0015] The beneficial effects of this utility model are: 1. This utility model, by using a lifting device and switching the position of the knob, changes the vertical movement position of the locking linkage and simultaneously alters the force state of the ratchet in the locking assembly. This causes the ratchet to maintain an outward ejection tendency when the knob is in the locked position and an inward retraction tendency when the knob is in the unlocked position, thus locking or releasing the vertical movement of the locking linkage. The vertical displacement change of the locking linkage is linked to the swaying of the traveling wheels, thus enabling synchronous switching between the clamping and releasing positions of each traveling wheel by switching the knob position. This utility model eliminates the need for individual disassembly and assembly of each traveling wheel, greatly simplifying the original operating procedure, significantly improving the disassembly and assembly efficiency of the testing equipment, and significantly reducing the labor intensity of workers.

[0016] 2. This utility model converts the worker's lifting action into a downward displacement of the locking linkage, thereby triggering the ratchet to engage and lock with the positioning slot, or disengaging the ratchet from the positioning slot to unlock. Since the locking and unlocking actions are automatically completed by the mechanical structure, the worker only needs to switch the knob's position and lift or lower the device to complete the assembly / disassembly operation. There is no need for precise alignment or latching operations while working at height, significantly reducing the difficulty of operation and the worker's physical exertion. Even a single person can easily complete the assembly / disassembly operation. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0025] Example 1: See attached Figures 1-2 A rapid installation structure for a rigid contact wire busbar testing device includes a base frame 1, two sets of traveling mechanisms, and a locking unit; Two sets of walking mechanisms are arranged opposite each other on the left and right sides above the base frame 1; each set of walking mechanisms includes a support plate 2, a drive assembly 3, and two walking components 4 arranged opposite each other on the support plate 2 in the front-to-back direction; the walking component 4 includes a walking wheel 41, a movable bracket 42, and a guide assembly 43; the walking wheel 41 is movably mounted above the movable bracket 42; the drive assembly 3 is used to drive the walking wheel 41 to rotate; the movable bracket 42 includes at least a locking link 421; the guide assembly 43 is vertically mounted on the movable bracket 42 and is used to drive the locking link 421 to move vertically by lifting and lowering; The locking unit includes a knob 5, a transmission mechanism 6, and four locking components 7. The transmission mechanism 6 includes a first connecting rod 61 and two transmission components 62 connected to the first connecting rod 61. The two transmission components 62 are respectively installed on the inner side of the two sets of walking mechanisms. Each transmission component 62 is simultaneously connected to two locking components 7. The four locking components 7 correspond one-to-one with four locking rods 421. The knob 5 is located on one of the transmission components 62 and is used to drive the two transmission components 62 to move synchronously. When the knob 5 is rotated to the locked position, the locking component 7 locks the vertical movement of the locking rods 421, thereby keeping the walking wheel 41 in the clamped position. When the knob 5 is rotated to the unlocked position, the locking component 7 releases the vertical movement of the locking rods 421, allowing the walking wheel 41 to switch to the released position.

[0026] As can be seen from the above structure, the base frame 1 serves as the mounting foundation for the entire device, and both sets of traveling mechanisms and the locking unit are mounted on top of the base frame 1. The two sets of traveling mechanisms are respectively located on the left and right sides of the base frame 1 and arranged facing each other, used to simultaneously clamp the busbar 0 and move it along its length. In each traveling mechanism, the support plate 2 is fixed above the base frame 1, providing support for the traveling component 4. The drive assembly 3 is used to drive the traveling wheels 41 to rotate, thereby driving the entire device to move along the length of the busbar 0.

[0027] In each traveling component 4, a traveling wheel 41 is mounted above a movable support 42, and its position can switch between a clamping position and a detached position as the movable support 42 moves. The movable support 42 includes at least a locking link 421, the vertical movement of which determines the swing angle of the traveling wheel 41. A guide assembly 43 is mounted on the movable support 42, and it is used to contact the locking link 421 during its downward movement, driving the locking link 421 to continue moving downward together.

[0028] The locking unit includes a knob 5, a transmission mechanism 6, and four locking components 7. A first connecting rod 61 is connected to two transmission components 62, and the knob 5 is mounted on one of the transmission components 62. Therefore, when the knob 5 rotates, it drives the two transmission components 62 to move synchronously. The four locking components 7 are respectively mounted on the two transmission components 62, and each transmission component 62 is simultaneously connected to two locking components 7. Each locking component 7 corresponds one-to-one with a locking link 421. Therefore, when the knob 5 rotates, it drives the two transmission components 62 to move synchronously, thereby causing the locking component 7 to change its locking status on the locking link 421. When the knob 5 rotates to the preset locking position, each locking component 7 can lock into its corresponding locking link 421, thereby restricting the vertical movement of the locking link 421 and maintaining the current vertical position of the traveling wheel 41, as shown in the attached diagram. Figure 1 Similarly, when the knob 5 is rotated to the preset unlock position, the locking assembly 7 unlocks the corresponding locking link 421, thereby releasing the vertical movement of the locking link 421 and allowing the wheel 41 to switch from the clamping position to the released position, disengaging from the busbar 0, as shown in the attached figure. Figure 1 The walking wheel 41 is located in the upper right corner.

[0029] Specifically, the initial position of the traveling wheel 41 is the detached position. During installation, the worker first places the entire device under the busbar 0. At this time, the four guide components 43 simultaneously contact the lower edge of the rigid busbar 0. Then, the knob 5 is rotated to the preset locking position, and then forcefully lifted upwards. The busbar 0 generates a downward reaction force on the guide components 43, thereby pushing the guide components 43 to slide downwards. During the downward movement, the lower end of the guide component 43 directly contacts the locking link 421, and drives the locking link 421 to continue moving downwards synchronously until the locking link 421 engages with the corresponding locking component 7 to lock. Finally, the traveling wheel 41 is maintained in the clamped position, stably clamping the busbar 0. When disassembling the device, the knob 5 is rotated to the preset unlocking position, releasing the vertical movement of the locking link 421, allowing the traveling wheel 41 to return to the detached position.

[0030] As can be seen, this utility model can simultaneously control the locking or unlocking of four locking components 7 through a single knob 5, allowing workers to lock or unlock all the positions of the traveling wheels 41 at the same time simply by rotating the knob 5, without having to operate them one by one. This significantly saves the operation time required for loading and unloading, greatly improves the disassembly and assembly efficiency of the testing equipment, and effectively reduces labor intensity.

[0031] It should be noted that the appendix Figure 1 To facilitate the demonstration of the two working positions of the traveling wheels 41, they are placed in the same picture. This does not represent the actual usage state during installation. In actual use, the four traveling wheels 41 are in the same state under the control of the knob 5, that is, simultaneously in the clamping position or simultaneously in the detached position.

[0032] Example 2: See attached Figures 1-7 Based on Embodiment 1, the guide assembly 43 includes a guide wheel 431, a guide shaft 432, a guide spring 433, and a sliding mounting base 434; the sliding mounting base 434 is fixedly connected to the middle of the locking link 421; the guide wheel 431 is located above the guide shaft 432; the guide shaft 432 is vertically and flexibly mounted on the sliding mounting base 434; the guide spring 433 is fitted and mounted above the sliding mounting base 434 and sleeved on the outer peripheral wall of the guide shaft 432.

[0033] As can be seen from the above structure, as shown in the appendix Figure 4As shown, the sliding mounting base 434 is fixed to the middle of the locking link 421, serving as the mounting base for the guide shaft 432. The guide shaft 432 is vertically and flexibly mounted on the sliding mounting base 434, with both its upper and lower ends extending out of the sliding mounting base 434. The guide wheel 431 is located above the guide shaft 432, for direct contact with the lower edge of the busbar 0. The guide spring 433 is fitted and mounted above the sliding mounting base 434, and sleeved on the outer peripheral wall of the guide shaft 432. When the guide wheel 431 is subjected to downward pressure, it drives the guide shaft 432 to move downward. At this time, the guide spring 433 is compressed. After the device leaves the busbar 0, the guide spring 433 extends and resets, providing upward elastic support for the guide shaft 432, allowing the guide shaft 432 to return to its initial position.

[0034] The movable support 42 also includes a fixed rod 422, a first tension spring 423, and a frame 424; the lower end of the fixed rod 422 is fixed to the support plate 2; the frame 424 includes a first connecting part 4241 and a second connecting part 4242; the walking wheel 41 is mounted on the first connecting part 4241; the upper end of the fixed rod 422 and the upper end of the locking rod 421 are respectively hinged to two opposite side walls of the second connecting part 4242; the two ends of the first tension spring 423 are respectively connected to the second connecting part 4242 and the fixed rod 422; the lower part of the locking rod 421 is provided with a protrusion 4211; when the guide shaft 432 moves downward, it drives the locking rod 421 to continue moving downward together by contacting the protrusion 4211; the lower part of the locking rod 421 is also provided with a positioning groove 4212.

[0035] As can be seen from the above structure, as shown in the appendix Figure 5 As shown, the movable support 42 also includes a fixing rod 422, a first tension spring 423, and a frame 424. The lower end of the fixing rod 422 is fixed to the support plate 2, serving as a fixed support point for the movable support 42. The frame 424 includes a first connecting part 4241 and a second connecting part 4242. The frame 424 is specifically L-shaped. The traveling wheel 41 is mounted on the first connecting part 4241, while the upper ends of the fixing rod 422 and the locking rod 421 are respectively hinged to two opposite side walls of the second connecting part 4242, as shown in the attached figure. Figure 5 As shown, the two opposite sidewalls are the front and rear sidewalls of the attached figure, so that the locking link 421 can drive the frame 424 to rotate by lifting itself.

[0036] When the locking linkage 421 moves downward, it drives the frame 424 to rotate clockwise around the hinge point at the upper end of the fixed rod 422, thereby causing the traveling wheel 41 to overcome the tension of the first tension spring 423 and swing clockwise, gradually rotating from the inclined loosening position to the horizontal clamping position, that is, from the attached Figure 7 The position change is attached Figure 5When the guide shaft 421 is in the clamped position, the traveling wheel 41 can contact and clamp the busbar 0. Then, the locking link 421 cooperates with the locking assembly 7 to lock the traveling wheel 41, keeping it in the clamped state. Similarly, when the locking link 421 is unlocked, it can move upward to reset. At this time, the first tension spring 423 will pull the frame 424 to rotate counterclockwise, thereby causing the traveling wheel 41 to swing counterclockwise, switching from the clamped position back to the released position, releasing the clamp on the busbar 0, and facilitating the disassembly of the device. In addition, the lower part of the locking link 421 is provided with a protrusion 4211 and a positioning slot 4212. When the guide shaft 432 moves downward, the lower end of the guide shaft 432 contacts the protrusion 4211, thereby driving the locking link 421 to move downward together. The positioning slot 4212 is used to cooperate with the locking assembly 7 to lock or unlock the vertical position of the locking link 421.

[0037] The locking assembly 7 includes a mounting base 71, a ratchet 72, an adjusting rod 73, and two second tension springs 74. The mounting base 71 is mounted on the support plate 2 and located below the guide assembly 43. The ratchet 72 is movably disposed in the mounting base 71, and the lower part of the ratchet 72 has a notch for engaging with the positioning slot 4212. The adjusting rod 73 is swayably disposed on the mounting base 71 and is connected to the transmission assembly 62. The two second tension springs 74 are connected between the ratchet 72 and the adjusting rod 73. The adjusting rod 73 is used to change the tension of the two second tension springs 74 on the ratchet 72 by its own sway. When the knob 5 is rotated to the locked position, the ratchet 72 tends to pop out of the mounting base 71. When the knob 5 is rotated to the unlocked position, the ratchet 72 tends to retract into the mounting base 71.

[0038] Two second tension springs 74 are slidably inserted in the mounting base 71; the first ends of the two second tension springs 74 are respectively connected to the upper and lower ends of the ratchet 72, and the second ends of the two second tension springs 74 are simultaneously connected to the upper and lower sides of the adjusting rod 73; the middle part of the adjusting rod 73 is hinged to the mounting base 71, and the upper end is connected to the transmission assembly 62.

[0039] As can be seen from the above structure, as shown in the appendix Figure 4 As shown, the locking assembly 7 is used to cooperate with the positioning slot 4212 to lock or unlock the vertical position of the locking link 421. The mounting base 71 is mounted on the support plate 2, providing a mounting base for the ratchet 72 and the adjusting rod 73, and the mounting base 71 has redundant space inside to allow the ratchet 72 and the second tension spring 74 to move. According to the attached... Figure 4 As shown in the figure, the ratchet 72 pops out of the mounting base 71, and the notch at the bottom of the ratchet 72 engages and locks with the positioning slot 4212.

[0040] Specifically, when knob 5 is rotated to the locked position, transmission assembly 62 drives adjusting rod 73 to swing clockwise around its central hinge point. At this time, the lower end of adjusting rod 73 swings towards ratchet 72, increasing the tension of the second tension spring 74 above adjusting rod 73, thus increasing its traction force on the upper end of ratchet 72. Conversely, the tension of the second tension spring 74 below adjusting rod 73 decreases, reducing its traction force on the upper end of ratchet 72. This causes ratchet 72 to maintain its tendency to pop outwards from mounting base 71. When locking link 421 moves downwards until positioning slot 4212 corresponds to the position of ratchet 72, ratchet 72 automatically pops out, and its lower notch engages with positioning slot 4212, thereby locking locking link 421 in its vertical position. When knob 5 is rotated to the unlocked position, transmission assembly 62 drives adjusting rod 73 to swing counterclockwise around its central hinge point, as shown in the attached diagram. Figure 6 As shown. At this time, the upper end of the adjusting rod 73 swings towards the ratchet 72, which reduces the stretching amplitude of the second tension spring 74 located above the adjusting rod 73, thus reducing its traction force on the upper end of the ratchet 72. Meanwhile, the stretching amplitude of the second tension spring 74 located below the adjusting rod 73 increases, thus increasing its traction force on the upper end of the ratchet 72. This causes the ratchet 72 to maintain its tendency to retract into the mounting base 71. However, since the positioning slot 4212 of the locking link 421 is still engaged with the notch of the ratchet 72, the ratchet 72 does not retract into the mounting base 71.

[0041] It should be noted that this design also prevents the traveling wheel 41 from being switched to the loose position simply by turning the knob 5 to the unlock position, as this would cause the device to fall directly off the manifold 0, posing a safety hazard. In this case, the entire device needs to be manually lifted further to allow the locking rod 421 to move downwards, separating the notch from the positioning slot 4212, thus unlocking the vertical position of the locking rod 421. At this point, the ratchet 72, due to its retracting tendency, retracts into the mounting base 71, no longer obstructing the vertical movement of the locking rod 421. In this situation, simply pulling the device downwards to separate the manifold 0 from the guide wheel 431 easily completes the disassembly of the entire device. This design ensures that the device will not abruptly fall off when the knob 5 is switched to the unlock position; instead, manual lifting of the device is required to achieve simultaneous unlocking of the four locking rods 421, guaranteeing the safety of the device.

[0042] The transmission assembly 62 includes a rotating rod 621, an end connector 622 passing through the rotating rod 621, and two transmission wheels 623; the end connector 622 is located at the front end of the rotating rod 621; the two ends of the first connecting rod 61 are respectively connected to the two end connectors 622 of the two transmission assemblies 62; the knob 5 is installed on the front side of one of the end connectors 622 and is coaxially arranged with the rotating rod 621; the transmission wheel 623 is connected to the upper end of the adjusting rod 73 of the corresponding locking assembly 7.

[0043] As can be seen from the above structure, when the knob 5 is rotated, it drives the corresponding end connector 622 and the rotating rod 621 to rotate synchronously, and transmits the rotational action to the end connector 622 of another transmission component 62 through the first connecting rod 61, so that the rotating rods 621 of the two transmission components 62 rotate synchronously. The two transmission wheels 623 are respectively connected to the upper end of the adjusting rod 73 of the corresponding locking component 7. When the rotating rod 621 rotates, the transmission wheel 623 drives the adjusting rod 73 to swing clockwise or counterclockwise around its central hinge point, thereby changing the tension state between the two second tension springs 74 and the ratchet 72, so as to realize the synchronous locking or unlocking of the four locking components 7 on the vertical position of the four locking rods 421.

[0044] Example 3: See attached Figures 1-7 Based on Embodiment 2, a fixed support plate 21 is provided on the front and rear sides of the support plate 2; the transmission assembly 62 also includes two T-shaped bushings 624; each T-shaped bushing 624 is installed and fitted on a fixed support plate 21; the rotating rod 621 of each transmission mechanism 6 passes through the two T-shaped bushings 624 and is rotatably supported on the two fixed support plates 21.

[0045] As can be seen from the above structure, according to the appendix Figure 2 and attached Figure 3 As shown, two fixed support plates 21 are respectively disposed on the front and rear sides of the support plate 2 to provide rotational support for the rotating rod 621. The fixed support plate 21 is an L-shaped support plate, and each T-shaped bushing 624 is installed and fitted onto one of the fixed support plates 21, located on the side wall of the fixed support plate 21 away from the locking assembly 7. The T-shaped bushing 624 is used to isolate the rotating rod 621 from direct contact with the fixed support plate 21, reducing the frictional resistance when the rotating rod 621 rotates, and also providing wear protection.

[0046] It also includes a ball plunger 8 located on the side wall of the support plate 2 near the transmission assembly 62; the end connector 622 is also provided with a rotating mating plate 625, and the side wall of the rotating mating plate 625 is provided with two limiting grooves 6251; the ball plunger 8 is provided with a ball 81 that is engaged with the limiting groove 6251 of the rotating mating plate 625.

[0047] As can be seen from the above structure, according to the appendix Figure 2 and attached Figure 3 As shown, the rotating mating plate 625 is mounted on the end connector 622 and rotates synchronously with the end connector 622. Two limiting grooves 6251 are provided on its side wall, corresponding to the locked and unlocked positions of the knob 5, respectively. The ball plunger 8 is fixedly installed on the side of the support plate 2 near the transmission assembly 62, and its ball 81 always maintains elastic contact with the side wall of the rotating mating plate 625. This design not only maintains the position of the knob 5 after rotation but also allows the worker to judge whether the knob has rotated to the correct position by the sound of the ball 81 engaging with the limiting groove 6251.

[0048] The drive assembly 3 includes two walking motors; each of the two walking motors is mounted on one of the two walking wheels 41 in any one of the walking mechanisms. As can be seen from the above structure, the walking motors drive the walking wheels 41 to rotate. The walking wheels 41 of the walking mechanism with the motors mounted act as the driving wheels, while the walking wheels 41 of the other walking mechanism act as driven wheels, rolling synchronously with the driving wheels. The entire device drives the two walking mechanisms to move smoothly and reliably along the length of the busbar 0 via the drive assembly 3, facilitating continuous inspection of the busbar 0 using inspection equipment.

[0049] At least one handle 9 is provided on each of the front and rear side walls of the base frame 1. As can be seen from the above structure, providing handles 9 on the side walls of the base frame 1 facilitates gripping by workers. Preferably, as... Figure 2 As shown, two handles 9 are provided on the front and rear side walls of the base frame 1.

[0050] Preferably, there can be two knobs 5, which are respectively located on the same transmission mechanism 6. One knob is located on the front side of the end connector 622, and the other is located on the end of the rotating rod 621 away from the end connector 622, so that the worker can rotate the knob 5 to adjust the position of the walking wheel 41 regardless of whether he is in front of or behind the device.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
