Description

Technical Field

[0001] This utility model relates to the field of subway and railway vehicle construction and maintenance technology, and in particular to a simple working platform for column-type and wall-type inspection pits. Background Technology

[0002] In railway vehicle depots, urban rail transit vehicle depots, and the maintenance of large industrial vehicles, column-type and wall-type inspection pits are key infrastructure, providing maintenance personnel with operating space under the vehicle to facilitate the maintenance of key components such as bogies and braking systems. However, existing workbenches have significant drawbacks: they are mostly integrated units, large in size and heavy in weight, requiring large equipment or multiple people to move them to the track. Column-type inspection pits have obstacles such as pillars around the track, restricting the transport path and making precise placement difficult; wall-mounted inspection pits have limited space, making them prone to collisions with the pit walls or surrounding facilities during transport, posing safety hazards and the risk of equipment damage. Meanwhile, the fixed size and height of the workbench cannot accommodate different inspection pit depths and the distance between the vehicle bottom and the pit bottom. In column-type inspection pits, if the height is too high, it may collide with vehicle parts; if it is too low, it will cause personnel to bend over to work, affecting efficiency and quality. In wall-type inspection pits, it is difficult to adapt to the bottom height of different vehicle models, and key inspection points are not easily accessible. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a simple working platform for column-type and wall-type inspection pits. It solves the technical problems that existing workbenches are mostly integrated designs, which are large in size and heavy in weight, making them inconvenient to transport and place, and prone to collisions with equipment during the process, resulting in equipment damage. Furthermore, their fixed size and height make them unsuitable for different vehicle inspection situations.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a simple working platform for column-type and wall-type inspection pits, including a track and a working platform mounted on the track. The working platform includes two connecting rods, with wheels rotatably connected to both ends of the connecting rods. Suspension rods are hung on both sides of the connecting rods, and insertion slots are arrayed on the suspension rods. A platform is provided between the two connecting rods, and insertion blocks adapted to the insertion slots are fixed to both sides of the platform. A locking component is provided on the suspension rods to fix the platform to the suspension rods.

[0005] A further improvement is that the end of the suspension rod has a U-shaped structure, and there are insertion holes on both sides of the U-shaped structure, into which bolts are inserted.

[0006] A further improvement is that a limit block is installed at the end of the connecting rod, and a wheel is rotatably connected to the limit block via a rotating shaft. The wheel is located above the track, and a brake pad is installed on the limit block to lock the wheel.

[0007] A further improvement is that the locking assembly includes a plug hole opened on the side of the suspension rod and extending into the plug groove, and plug holes are also opened on the side of the plug block. A spring cavity is opened in the plug hole, a locking rod is inserted into the plug hole, and a spring sleeved on the locking rod is installed in the spring cavity.

[0008] A further improvement is that the platform includes a fixed platform and an extended platform. The fixed platform has a storage groove, and the extended platform is equipped with an extended plate that matches the storage groove. A connecting rod is inserted into a through hole on the fixed platform, and the extended plate has an array of through holes that match the connecting rod.

[0009] A further improvement is that magnetic strips are symmetrically installed on both sides of the connecting rod, and magnetic blocks adapted to the magnetic strips are installed on the suspension rod.

[0010] By employing the above technical solution, this utility model provides a simple working platform for column-type and wall-type inspection pits, which has at least the following beneficial effects: 1. This utility model breaks down the traditional integrated work platform into multiple modules and connects them by splicing them together, making it easier to transport and place, more flexible in operation, and allowing the plug blocks to be inserted into plug slots of different heights according to the different maintenance positions of the vehicle, thereby adjusting the height of the tabletop accordingly. This avoids the need for workers to frequently bend over to work on a tabletop of fixed height, which would affect work efficiency.

[0011] 2. This utility model allows the locking rod to slide into the insertion hole and compress the spring. Then, the insertion block is inserted into the insertion slot. After releasing the locking rod, the spring returns to its original position under its own elasticity, thereby pushing the locking rod into the insertion hole on the insertion block. This quickly completes the fixing of the insertion block without the need for additional tools, and the disassembly and assembly are convenient.

[0012] 3. This utility model allows the extension plate, which was originally inserted into the storage groove in the fixed platform, to slide out by pulling out the plug rod and then pulling the extension surface until the platform is extended to the required length. Then the plug rod is reinserted into the through hole in the fixed platform and the extension plate to fix the length, thereby expanding the space of the platform and making it easier for workers to perform maintenance while lying down.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Currently available workbenches are mostly integrated designs, resulting in large size and heavy weight, making them inconvenient to transport and place. They are also prone to collisions with equipment during transport, leading to equipment damage. Furthermore, their fixed size and height make them unsuitable for different vehicle inspection locations. This embodiment provides a simple column-type or wall-mounted inspection pit work platform. It breaks down the traditional integrated work platform into multiple modules, which are connected by splicing. This makes it easier to transport and place, and the height can be adjusted specifically according to the vehicle's inspection location. Please refer to... Figures 1-5This simple working platform for column-type and wall-type inspection pits includes a track 1 and a working platform 2 mounted on the track 1. The working platform 2 includes two connecting rods 21, with wheels 22 rotatably connected to both ends of the connecting rods 21. Suspension rods 23 are hung on both sides of the connecting rods 21, and insertion slots 24 are arrayed on the suspension rods 23. A platform 25 is provided between the two connecting rods 21, and insertion blocks 26 that are adapted to the insertion slots 24 are fixed to both sides of the platform 25. A locking assembly 3 is provided on the suspension rods 23 to fix the platform 25 to the suspension rods 23. When vehicle maintenance is required, the wheels 22 at both ends of the connecting rods 21 are mounted on the track 1, and then... The suspension rod 23 is hung on both sides of the connecting rod 21. Then, the plug blocks 26 on both sides of the platform 25 are inserted into the plug slots 24 on the suspension rod 23, thereby quickly completing the overall assembly of the work platform 2. The plug blocks 26 can be inserted into the plug slots 24 at different heights according to the different maintenance positions of the vehicle, thereby adjusting the height of the platform 25. Compared with the traditional integrated fixed workbench, it is easier to transport and place, and the operation is more flexible. It avoids the problem of workers having to bend over frequently due to the fixed height of the platform 25, which affects work efficiency. It also avoids the situation where the entire workbench is transported and collided with the vehicle equipment, resulting in damage to the vehicle equipment.

[0018] Specifically, the end of the suspension rod 23 has a U-shaped structure, and there are insertion holes on both sides of the U-shaped structure. Bolts 27 are inserted into the insertion holes. When the bolts 27 are inserted into the insertion holes, the end of the suspension rod 23 is locked, thereby preventing the table 25 from shaking during the operation, which would cause the end of the suspension rod 23 to shake, or even cause the suspension rod 23 to fall off the connecting rod 21, thus improving the safety of the operation.

[0019] Since the movement of the wheel 22, which in turn moves the platform 25, may be caused by the force applied or the turning action of the staff during maintenance, a limit block 41 is installed at the end of the connecting rod 21 in this device. The wheel 22 is rotatably connected to the limit block 41 via a rotating shaft, and the wheel 22 is located above the track 1. A brake pad 42 is installed on the limit block 41 to lock the wheel 22. When it is necessary to move the work platform 2, the platform 25 is pulled to move, thereby causing the wheel 22 to rotate and move on the limit block 41 via the rotating shaft. After the position of the platform 25 is adjusted, the brake pad 42 can be pressed to lock the wheel 22, so as to prevent the staff from applying force to move the wheel 22 during maintenance, which would affect the maintenance work.

[0020] To prevent the plug block 26 from falling out of the plug slot 24, the device also includes a locking assembly 3. The locking assembly 3 includes a plug hole 31 located on the side of the suspension rod 23 and extending into the plug slot 24. The plug block 26 also has plug holes 31 on its side. A spring cavity 32 is formed within each plug hole 31, and a locking rod 33 is inserted into the plug hole 31. A spring 34, sleeved on the locking rod 33, is installed within the spring cavity 32. When the plug block 26 is inserted into the plug slot 24... First, pull the locking lever 33 to slide it into the insertion hole 31 and compress the spring 34. Then, insert the insertion block 26 into the insertion slot 24. After that, release the locking lever 33. At this time, the spring 34 will return to its original position under its own elasticity, thereby pushing the locking lever 33 into the insertion hole 31 on the insertion block 26. This quickly completes the fixing of the insertion block 26, preventing it from slipping out of the insertion slot 24 and causing the tabletop 25 to fall and injure people. Moreover, no additional tools are required, making the disassembly and assembly operations more convenient.

[0021] Furthermore, magnetic strips 51 are symmetrically installed on both sides of the connecting rod 21, and magnetic blocks 52 that are compatible with the magnetic strips 51 are installed on the suspension rod 23. When the suspension rod 23 is suspended on the connecting rod 21, when the magnetic blocks 52 on the suspension rod 23 come into contact with the magnetic strips 51 on the connecting rod 21, the two automatically attract each other, thereby quickly completing the positioning and suspension of the suspension rod 23.

[0022] Example 2 Since inspecting the underside of a vehicle often requires workers to lie on the platform 25 and utilize multiple tools, a fixed platform 25 may not provide sufficient space. Therefore, based on Embodiment 1, as... Figures 1-5 As shown, the platform 25 in the device includes a fixed platform 251 and an extended platform 252. The fixed platform 251 has a storage groove 253, and the extended platform 252 is equipped with an extended plate 254 that matches the storage groove 253. A connecting rod 255 is inserted into a through hole on the fixed platform 251, and the extended plate 254 has an array of through holes that match the connecting rod 255. The connecting rod 255 is pulled out, and then the extended platform 252 is pulled to slide the extended plate 254, which was originally inserted into the storage groove 253 in the fixed platform 251, until the platform 25 is extended to the required length. Then the connecting rod 255 is reinserted into the through holes on the fixed platform 251 and the extended plate 254 to fix the length, thereby expanding the space of the platform 25, which is convenient for workers to perform supine maintenance.
