Description

Technical Field

[0001] This application relates to the field of work platform technology, and in particular to an anti-collision device for aerial work platforms. Background Technology

[0002] Aerial work platforms are ideal equipment for construction, maintenance, and repair work in industries such as power, communications, transportation, municipal engineering, fire fighting, rescue, and construction. With the booming development of my country's national economy, the demand for aerial work platforms is rapidly increasing. Aerial work platforms come in various lifting methods, including folding, telescopic, and hybrid types, with working heights ranging from tens of meters to several meters; trailer-mounted aerial work platforms require a work platform.

[0003] In practical use, it has been found that traditional devices only have simple anti-collision strips on the left and right sides of the platform, which can only achieve basic buffering and cannot cope with large impact forces. When a collision occurs, the platform is prone to violent shaking, which can cause personnel inside the platform to be injured due to inertia colliding with the inner wall. Therefore, we have proposed an anti-collision device for aerial work platforms to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, which easily lead to injuries to personnel inside the platform due to inertia colliding with the inner walls on both sides, and to propose an anti-collision device for aerial work platforms.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a collision avoidance device for an aerial work platform, comprising a work platform, with protective mechanisms provided on both inner walls of the work platform, hollow seats fixedly installed on both sides of the work platform, a piston mechanism provided inside the hollow seats, and a collision avoidance mechanism provided on the outer side of the work platform; fixed boxes fixedly installed on both sides of the work platform, the hollow seats located inside the fixed boxes, the same rotating shaft rotatably installed on the front inner wall and the rear inner wall of the fixed boxes, plate holes opened on the outer side of the fixed boxes, a gear mechanism provided between the rotating shaft and the fixed boxes, and a support mechanism provided on the fixed boxes.

[0006] A further feature of this application is that the protective mechanism includes two air cushions and two protective pads, with air cushions provided on both inner walls of the working platform, and protective pads provided on the adjacent side of the two air cushions.

[0007] By adopting the above technical solution and setting up a protective mechanism, the flexible support of the air cushion and the buffering effect of the protective pad provide all-round passive protection for the workers inside the platform, preventing personnel from making hard contact with the inner wall of the platform due to collision inertia.

[0008] A further provision of this application is that the anti-collision mechanism includes an anti-collision plate and an anti-collision pad, with an anti-collision plate provided on the outside of the hollow seat and an anti-collision pad provided on the outside of the anti-collision plate.

[0009] By adopting the above technical solution and by setting up an anti-collision mechanism, when the two sides of the work platform are subjected to external collisions, the impact pads first absorb the initial impact force through their own elastic deformation, which can reduce the direct damage to the anti-collision plate from the collision.

[0010] A further configuration of this application is as follows: the piston mechanism includes a piston plate and a piston rod, the piston plate is slidably installed inside the hollow seat, the piston rod is fixedly installed on the outside of the piston plate, the other end of the piston rod is fixedly connected to the inner side of the corresponding anti-collision plate, and a spring is sleeved on the piston rod, with both ends of the spring fixedly connected to the anti-collision plate and the hollow seat respectively.

[0011] By adopting the above technical solution and by setting up a piston mechanism, the anti-collision plate moves inward under the impact force, which can drive the piston rod to push the piston plate to slide along the inner side of the hollow seat. The gas in the hollow seat is compressed and can be quickly filled into the air cushion of the protective mechanism through the vent pipe.

[0012] A further configuration of this application is as follows: the gear mechanism includes a first rack plate, a second rack plate, and a gear. The first rack plate is fixedly installed on the inner side of the anti-collision plate. The first rack plate is slidably connected to the inner wall of the bottom of the fixed box. The second rack plate is slidably installed on the inner wall of the top of the fixed box. A gear is fixedly sleeved on the rotating shaft. The gear meshes with the first rack plate and the second rack plate. The first rack plate is adapted to the plate hole.

[0013] By adopting the above technical solution and by setting a gear mechanism, the anti-collision plate can drive the support rod to extend outward when it is hit.

[0014] A further configuration of this application is: the support mechanism includes a support rod and a support ball, the support rod is fixedly installed on the outer side of the second rack plate, the other end of the support rod extends to the outer side of the fixed box, and the other end of the support rod is provided with a support ball.

[0015] By adopting the above technical solution and setting up a support mechanism, the support rod can drive the support ball to extend outward, so that the support ball can make close contact with the surface of the colliding object. The rigid support of the support rod enhances the anti-overturning ability of the work platform and avoids the platform from tipping over due to collision.

[0016] A further feature of this application is that an air hole is provided on the outer side of the hollow seat, and a common air vent is provided between the hollow seat and the air cushion.

[0017] By adopting the above technical solution, and by setting air holes and ventilation pipes, the air pressure inside the hollow seat can be balanced through the air holes, and air can be inflated into the air cushion through the ventilation pipes.

[0018] A further feature of this application is that a protective door is provided on the front side of the work platform, and a handle is provided on the protective door.

[0019] By adopting the above technical solution and installing a protective door, staff can easily open and close the door using a handle, thereby increasing the safety of the left and right platforms.

[0020] The beneficial effects of this application are: 1. Through the cooperation of anti-collision pads, anti-collision plates, piston rods, piston plates, vent pipes, air cushions and protective pads, when the two sides of the work platform are subjected to external collisions, the gas in the hollow seat is compressed and can be quickly filled into the air cushion of the protective mechanism through the vent pipe. This allows the air cushion to expand rapidly and push the protective pad on the surface toward the center of the work platform. It can achieve the purpose of providing all-round passive protection for the workers inside the platform through the flexible support of the air cushion and the buffering effect of the protective pad, preventing the personnel from making hard contact with the inner wall of the platform due to the collision inertia. 2. Through the cooperation of the first rack plate, gear, second rack plate, support rod and support ball, when the anti-collision plate is hit, the support rod of the support mechanism extends outward of the fixed box, and finally the support ball makes close contact with the surface of the colliding object. This can enhance the anti-overturning ability of the working platform by means of the rigid support of the support rod, and prevent the platform from overturning due to collision.

A gear mechanism is provided between the rotating shaft 401 and the fixed boxes 4. A support mechanism is provided on the fixed boxes 4.

[0026] Specifically, the protective mechanism includes two air cushions 101 and two protective pads 102. Air cushions 101 are installed on both inner walls of the working platform 1, and protective pads 102 are installed on the adjacent side of the two air cushions 101.

[0027] Specifically, the anti-collision mechanism includes an anti-collision plate 3 and an anti-collision pad 301. An anti-collision plate 3 is provided on the outside of the hollow seat 2, and an anti-collision pad 301 is provided on the outside of the anti-collision plate 3.

[0028] Specifically, the piston mechanism includes a piston plate 201 and a piston rod 202. The piston plate 201 is slidably installed inside the hollow seat 2, and the piston rod 202 is fixedly installed on the outside of the piston plate 201. The other end of the piston rod 202 is fixedly connected to the inner side of the corresponding anti-collision plate 3. A spring 203 is sleeved on the piston rod 202, and the two ends of the spring 203 are fixedly connected to the anti-collision plate 3 and the hollow seat 2, respectively.

[0029] Specifically, the gear mechanism includes a first rack plate 5, a second rack plate 501, and a gear 502. The first rack plate 5 is fixedly installed on the inner side of the anti-collision plate 3. The first rack plate 5 is slidably connected to the bottom inner wall of the fixed box 4. The second rack plate 501 is slidably installed on the top inner wall of the fixed box 4. The gear 502 is fixedly sleeved on the rotating shaft 401. The gear 502 meshes with the first rack plate 5 and the second rack plate 501. The first rack plate 5 is adapted to the plate hole.

[0030] Specifically, the support mechanism includes a support rod 6 and a support ball 601. The support rod 6 is fixedly installed on the outside of the second rack plate 501, and the other end of the support rod 6 extends to the outside of the fixed box 4. The other end of the support rod 6 is provided with a support ball 601.

[0031] Specifically, the hollow seat 2 has air holes on its outer side, and the hollow seat 2 and the air cushion 101 have the same air pipe 204.

[0032] Specifically, a protective door is installed on the front side of the work platform 1, and a handle is installed on the protective door.

[0033] In this application, during operation, when the two sides of the work platform 1 are subjected to external collisions, the anti-collision pads 301 of the anti-collision mechanism first absorb the initial impact force through their own elastic deformation, which can reduce the direct damage to the anti-collision plate 3. Under the action of the impact force, the anti-collision plate 3 moves inward, which can drive the piston rod 202 to push the piston plate 201 to slide along the inner side of the hollow seat 2. At this time, the spring 203 sleeved on the piston rod 202 is compressed, which can use the elastic potential energy of the spring 203 to form a reverse buffer force, further attenuating the collision energy, and achieving the purpose of avoiding rigid impacts from damaging the main structure of the work platform 1. During the sliding process of the piston plate 201, the gas in the hollow seat 2 is compressed, which can be quickly filled into the air cushion 101 of the protective mechanism through the vent pipe 204, which can make the air cushion 101 expand rapidly and push the protective pad 102 on the surface toward the center of the work platform 1. It can achieve all-round passive protection for the workers in the platform through the flexible support of the air cushion 101 and the buffering effect of the protective pad 102, preventing personnel from being injured by the collision inertia. The purpose is to achieve rigid contact with the inner wall of the platform; simultaneously, when the anti-collision plate 3 moves, it synchronously drives the first rack plate 5 of the gear mechanism to slide inward along the inner wall of the bottom of the fixed box 4. The first rack plate 5 meshes with the drive gear 502 to rotate around the rotating shaft 401. The gear 502 then drives the second rack plate 501 to slide outward along the inner wall of the top of the fixed box 4, causing the support rod 6 of the support mechanism to extend outward from the fixed box 4. Finally, the support ball 601 makes close contact with the surface of the colliding object, which can achieve rigid support enhancement by means of the support rod 6. The anti-overturning capability of the work platform 1 is designed to prevent the platform from tipping over due to collision. After the collision, the rebound force of the spring 203 pushes the anti-collision plate 3, piston rod 202 and piston plate 201 to reset. The hollow seat 2 draws in outside air through the air hole, causing the gas in the air cushion 101 to flow back to the hollow seat 2. The air cushion 101 contracts and resets. At the same time, the first rack plate 5 slides in the opposite direction, driving the gear 502 and the second rack plate 501 to reset. The support rod 6 retracts into the fixed box 4, and the device returns to its initial state, waiting for the next collision protection.
