[0002] Valve hall operation vehicle refers to a special vehicle used in power plants or factories for the operation and maintenance of various valves. It is usually equipped with some special devices and tools so that operators can easily perform tasks such as valve opening and closing, inspection, maintenance and replacement.

[0003] Operating a valve platform work vehicle requires certain professional knowledge and experience. The gap between the work vehicle and the valve tower is generally controlled based on the driver's experience, which is quite difficult. The aforementioned patent adjusts the gap in real time by measuring the spatial position of the work platform. However, when the work platform is raised to a high altitude, the work vehicle cannot be moved to ensure the safety of the operators. Adjustments can only be made before the work platform is raised, and it is also necessary to ensure that the gap between the work platform and the valve tower is not too large or too small. After the work vehicle rises to its highest point, the stability deteriorates due to stress issues, causing the work platform to shake and collide with the valve tower, leading to safety problems and potential damage to the work platform or valve tower.

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-2 As shown, a scissor lift platform for power grid valve halls includes a traveling vehicle body 1 and a working platform 2. The working platform 2 is mounted on top of the traveling vehicle body 1 via a scissor lift structure 3. Both the traveling vehicle body 1 and the working platform 2 are existing technologies and will not be described in detail here. The scissor lift structure 3 is composed of multiple intersecting rods connected by a pivot. These rods are typically arranged in an "X" shape and can rotate around the pivot, resembling the crossed part of scissors. The entire structure can perform longitudinal telescopic movement, enabling lifting and lowering control of the working platform 2. The working platform 2 is mounted on top of the scissor lift structure 3, allowing it to be raised and lowered vertically to adapt to different working height requirements. Multiple buffer devices a are provided on the outer wall of the working platform 2. Each buffer device a includes a fixed plate 41 and an airbag 42 located on one end face of the fixed plate 41. The other end face of the fixed plate 41 is connected and fixed to the side wall of the working platform 2. A control pump body 411 is provided for inflating and deflating the airbag 42. The airbag 42 and the control pump body 411 are existing products on the market and are considered prior art, so they will not be described in detail here. The control pump body 411 is connected to the airbag 42 and can inflate or deflate the airbag 42 to facilitate replacement and maintenance of the airbag 42 after deflating. The control pump body 411 can also adjust the inflation amount of the airbag 42 according to the actual gap to control the size of the airbag 42. The other end face of the fixing plate 41 is fixed to the side wall of the working platform 2 and connected to the outside of the working platform 2. During operation, it can increase the soft support between the working platform 2 and the valve tower, reduce the shaking of the working platform 2, enhance the stability of the working platform 2 during operation, protect the working platform 2 and the operators, increase safety, and at the same time avoid direct contact and collision between the working platform 2 and the valve tower, which would cause damage to the working platform 2 and the valve tower, and ensure smooth operation.

[0020] like Figure 2As shown, a protective cover 421 is provided on the outside of the airbag 42, completely surrounding the airbag 42 and connecting to the edge of the fixing plate 41. This provides comprehensive protection for the airbag 42 and maintains the soft support function of the airbag 42. The protective cover 421 is made of a material with high elasticity and scratch resistance (such as silicone, rubber, etc.) to prevent the airbag 42 from being scratched by the valve tower components, reduce the shaking of the valve tower, and protect the airbag 42 from damage. An annular protrusion 412 is provided on the edge of the fixing plate 41, and an annular connector 422 is provided on the edge of the protective cover 421. The annular connector 422 cooperates with the annular protrusion 412. The inner side of the protective cover 421 is fixed to the annular protrusion 412 by screws. The annular connector 422 is fixed to the edge of the protective cover 421, so that the protective cover 421 can be fixed to the inner side of the annular protrusion 412 by the annular connector 422, thereby forming a protective enclosure for the airbag 42. The protective cover 421 needs to completely surround the airbag 42 and connect to the edge of the fixing plate 41. Its structural design takes into account easy installation and disassembly for daily inspection and maintenance. The design of the annular protrusion 412 and the annular connector 422, fixed by screws, enhances the stability and reliability of the protective cover 421. Figure 2-4As shown, the fixed plate 41 has multiple clamping devices on the side connected to the side wall of the working platform 2, which can clamp the horizontal or vertical bars of the working platform 2. The clamping devices include a first clamping part 51 and a second clamping part 52 arranged symmetrically. The clamping devices on the fixed plate 41 can stably clamp the horizontal or vertical bars of the working platform 2 through the cooperation of the first clamping part 51 and the second clamping part 52. Multiple clamping devices can be set as needed to clamp the horizontal or vertical bars on the working platform. The first clamping part 51 and the second clamping part 52 can be arc-shaped to clamp the columnar rod or rectangular to clamp the rectangular rod, which enhances the connection stability between the working platform 2 and the valve tower and reduces the safety risks caused by unstable connection. The first clamping part 51 can move relative to the second clamping part 52. The second clamping part 52 is fixedly connected to the end face of the fixed plate 41. The end face of the fixed plate 41 is provided with at least one limiting strip 413 arranged along the moving direction of the first clamping part 51. The first clamping part 51 is close to the fixed plate 41. One side of the first clamping part 51 is provided with a slot that mates with the limiting strip 413. The first clamping part 51 has a protrusion 511 on its contact surface that contacts the second clamping part 52 and is away from the fixing plate 41. The second clamping part 52 has a groove 521 that mates with the protrusion 511. Through the cooperation of the limiting strip 413 and the slot, the first clamping part 51 is guided during movement, achieving stable movement of the first clamping part 51 relative to the second clamping part 52, and enhancing the stability when the first clamping part 51 and the second clamping part 52 are clamped together. The fit between the protrusion 511 and the groove 521 ensures a stable connection between the first clamping part 51 and the second clamping part 52. When the locking rod 53 is not inserted into the first clamping part 51 and the second clamping part 52, the pre-assembly positioning is achieved, so that the first clamping part 51 and the second clamping part 52 can be aligned more quickly and accurately for efficient assembly. Multiple buffer devices a can be fixed on the outer wall of the work platform 2 through the clamping device, and fixed in different positions according to actual needs, making use and maintenance more convenient.

[0021] like Figure 3-4As shown, a locking rod 53 is provided on the side of the second clamping part 52 near the fixed plate 41, passing through the second clamping part 52 and the first clamping part 51. The locking rod 53 is inserted into the second clamping part 52 and the first clamping part 51 near the fixed plate 41. One end of the locking rod 53 is fixed to the second clamping part 52, and the other end of the locking rod 53 is inserted into the first clamping part 51. The first clamping part 51 can move relative to the locking rod 53. One end of the locking rod 53 is fixedly connected to the second clamping part 52. The locking rod 53 can be inserted into the second clamping part 52 by adhesive and fixedly connected to the second clamping part 52, or it can be inserted into the second clamping part 52 by interference fit. The locking rod 53 is fixedly connected to the second clamping part 52, or it can be threaded through the second clamping part 52 and fixedly connected to the second clamping part 52. The other end is movably connected to the first clamping part 51. The first clamping part 51 has a fixing groove 512 corresponding to the periphery of the locking rod 53. The locking rod 53 has a limiting plate 531 located in the fixing groove 512 and cooperating with the inner wall of the fixing groove 512. The limiting plate 531 is threadedly connected to the locking rod 53 to facilitate its insertion and assembly on the first clamping part 51 and the second clamping part 52, and to fix the limiting plate 531. One end of the locking rod 53 passes through the first clamping part 51 and is located in the fixing groove 512. Within 12, a limiting plate 531 is fixed to the side wall of a locking rod 53. The end of the locking rod 53 protrudes from the limiting plate 531 and is threaded. The limiting plate 531 is located within a fixing groove 512, and the side wall of the locking rod 53 mates with the inner wall of the fixing groove 512. A telescopic spring 532, corresponding to the periphery of the locking rod 53, is provided within the fixing groove 512 and connects to the limiting plate 531 and the inner wall of the fixing groove 512. The end of the locking rod 53 extends outside the fixing groove 512 and is threadedly connected to a locking nut 533. Both ends of the telescopic spring 532 are connected to the end face of the limiting plate 531 and the inner end face of the fixing groove 512, respectively. When the first clamping part 51 moves, the telescopic spring 532 extends and retracts synchronously. When the first clamping part 51 is pulled open, the telescopic spring 532 contracts, causing the first clamping part 51 and the second clamping part 52 to be located on both sides of the horizontal or vertical bar of the work platform 2. Then, the first clamping part 51 is released, and the telescopic spring 532 extends to act on the first clamping part 51, causing the first clamping part 51 and the second clamping part 52 to merge and clamp onto the horizontal or vertical bar of the work platform 2. Subsequently, the locking nut 533 is tightened on the end of the locking rod 53 and the locking nut 533 abuts against the outer wall of the first clamping part 51, thereby fixing the locking rod 53 on the second clamping part 52 and locking the first clamping part 51 and the second clamping part 52.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
