Description

Technical Field

[0001] The present invention relates to the field of bridge construction, and more particularly to a high-altitude operation safety platform for bridge construction. Background Art

[0002] During the process of bridge construction or maintenance, such as the installation of drain pipes, the repair of wing plate defects, or the installation of rain shelters on the outer side of the bridge eaves, etc., it is often necessary to use construction auxiliary equipment to get close to the construction working surface. Sometimes, due to the limitations of the environmental conditions where the bridge is located, it is impossible to build a construction support under the bridge, or even if a construction support is built, it is not convenient for construction.

[0003] During the process of bridge pouring construction, it is often necessary to carry out caulking pouring on both sides of the bridge. Since the working platform is installed in the middle, construction workers often need to lean out to construct the side walls, which increases the safety risk of high-altitude operations and poses a great potential accident hazard. Therefore, we have made improvements and proposed a high-altitude operation safety platform for bridge construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-altitude operation safety platform for bridge construction, which solves the problem that since the working platform is installed in the middle, construction workers often need to lean out to construct the side walls, increasing the safety risk of high-altitude operations and posing a great potential accident hazard.

[0005] In order to achieve the above-mentioned invention purpose, the present invention provides a high-altitude operation safety platform for bridge construction, including a vehicle frame, and a lifting and telescoping mechanism is arranged on the top of the vehicle frame. The high-altitude operation safety platform further includes:

[0006] A working platform, which is installed on the top of the lifting and telescoping mechanism and is driven by the lifting and telescoping mechanism to move up and down;

[0007] A translation platform, which is slidably installed on the inner side wall of the working platform and can slide horizontally along the working platform;

[0008] A horizontal driving mechanism, which is installed in the working platform and is used to drive the translation platform to slide horizontally along the working platform;

[0009] A safety protection component, which is installed between the working platform and the translation platform, and can expand to form a protective fence when the translation platform slides out;

[0010] A working door, which is rotatably connected to the end of the safety protection component and can be clamped with the safety protection component to form a closed state.

[0011] As a preferred technical solution of the present invention, the lifting and telescopic mechanism includes a main lifting rod and a secondary lifting rod. The middle and both ends of the main lifting rod and the secondary lifting rod are respectively rotatably connected by a first pin shaft. One ends of the main lifting rod and the secondary lifting rod at the top and bottom are respectively rotatably connected to the vehicle frame and the working platform. The other ends of the main lifting rod and the secondary lifting rod at the top and top are respectively connected with sliders. Slide rails for the sliders to slide are respectively connected to the vehicle frame and the working platform. The sliders slide within the slide rails to maintain the balance of the main lifting rod and the secondary lifting rod. A hydraulic push rod is also rotatably connected to the middle of the vehicle frame. A sliding frame is fixedly connected to the side wall of one of the main lifting rods. One end of the hydraulic push rod is slidably connected to the sliding frame. When the hydraulic push rod extends, it can drive the main lifting rod and the secondary lifting rod to fold with each other. During the folding process, the sliders slide within the slide rails for contraction, realizing the displacement between the main lifting rod and the secondary lifting rod. When the hydraulic push rod contracts, the lowering of the working platform can be completed.

[0012] As a preferred technical solution of the present invention, a safety railing is fixedly connected to the top of the working platform. The safety railing is arranged along the edge of the working platform to form a U-shaped semi-surrounding shape, protecting the construction workers through the safety railing and improving the safety level.

[0013] As a preferred technical solution of the present invention, the horizontal driving mechanism includes a driving motor fixedly installed on the outer wall of the working platform. The output end of the driving motor is fixedly connected with a driving pulley. A synchronous belt is clamped on the outer wall of the driving pulley. One end of the synchronous belt is clamped with a driven pulley. A gear is fixedly connected to the middle of the driven pulley through a connecting rod. A toothed plate is engaged with the outer wall of the gear. The toothed plate is fixedly installed at the bottom of the translation platform. The connecting rod is rotatably connected to the working platform through a bearing. When the translation platform needs to extend, start the driving motor. The driving motor drives the driving pulley to move. The driving pulley drives the driven pulley to move, thereby driving the gear to move. The gear meshes with the toothed plate to push out the translation platform.

[0014] As a preferred technical solution of the present invention, a plurality of equally spaced pulleys are also fixedly installed on the inner side wall of the working platform. A sliding groove is formed on the side wall of the translation platform. The pulleys are embedded in the sliding groove to support the translation platform. The plurality of pulleys can improve the stability of the translation platform.

[0015] As a preferred technical solution of the present invention, the safety protection component includes support plates fixedly connected to the top of the working platform and the top of the translation platform. A sliding plate is fixedly connected to the bottom of the side wall of the support plate. A main safety railing is slidably connected to the inner side wall of the sliding plate. Secondary safety railings are respectively rotatably connected to the middle and both ends of the main safety railing. One ends of the two secondary safety railings at both ends are rotatably connected to the support plate. When the translation platform extends, the main safety railing and the secondary safety railings are pulled to unfold, thereby forming a protective net.

[0016] As a preferred technical solution of the present invention, a strip slide groove is opened in the middle of the skateboard, and a cylindrical slider is provided at the end of the main guardrail. The cylindrical slider is slidably installed inside the strip slide groove, and the cylindrical slider slides inside the skateboard when folded or extended.

[0017] As a preferred technical solution of the present invention, a clamping block is provided on the side wall of the operating door, a clamping groove is provided in the middle of the clamping block, and the clamping block is a magnet block.

[0018] As a preferred technical solution of the present invention, the support plate is made of iron, and the side wall of the support plate is also fixedly connected with a pin shaft seat, the inner side wall of the pin shaft seat is slidably connected with a pin, and a spring is fixedly connected between the pin and the pin shaft seat, and the pin is adapted to the slot. When the card block approaches the pin, it pushes the pin upward to compress the spring. When the pin is aligned with the slot, the pin is automatically inserted into the slot under the push of the spring, thereby fixing the card block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of the present invention:

[0021] Through the arrangement of the frame, telescopic mechanism, working platform, translation platform, horizontal driving mechanism, safety protection components and working door, the extension of the hydraulic push rod can push the lifting main rod and the lifting auxiliary rod to fold each other, thereby driving the working platform to move upward and pushing the staff to the construction area. When the construction workers need to work at a close distance, the drive motor is started, and the drive motor drives the driving pulley to rotate, thereby driving the driven pulley through the synchronous belt, and the driven pulley drives the gear to rotate the meshing gear plate to push the translation platform to the construction area. At the same time, the safety protection components extend with the movement of the translation platform to protect the personnel. When it is necessary to get on and off the personnel, the latch is pulled upward to compress the spring, and the working door can be opened at this time. When closing, the card block can absorb the support plate. When it fits the support plate, the card block lifts the latch, and the spring automatically pushes the latch to achieve plug-in fixation.

[0042] An operation door 70 is rotatably connected to the end of the safety protection component 60 and can be snap-connected to the safety protection component 60 to form a closed state.

[0043] As a preferred embodiment, on the basis of the above method, further, the lifting and telescoping mechanism 20 includes a lifting main rod 21 and a lifting auxiliary rod 22. The middle and both ends of the lifting main rod 21 and the lifting auxiliary rod 22 are respectively rotatably connected by a first pin shaft 23. One ends of the lifting main rod 21 and the lifting auxiliary rod 22 located at the top and bottom are respectively rotatably connected to the vehicle frame 10 and the working platform 30. The other ends of the lifting main rod 21 and the lifting auxiliary rod 22 located at the top and the top are respectively connected with sliders 24. Slide rails 25 for the sliders 24 to slide are respectively connected to the vehicle frame 10 and the working platform 30. The sliders 24 slide in the slide rails 25 to keep the lifting main rod 21 and the lifting auxiliary rod 22 balanced. A hydraulic push rod 26 is also rotatably connected to the middle of the vehicle frame 10. A sliding frame 27 is fixedly connected to the side wall of one of the lifting main rods 21. One end of the hydraulic push rod 26 is slidably connected to the sliding frame 27. When the hydraulic push rod 26 extends, it can drive the lifting main rod 21 and the lifting auxiliary rod 22 to fold with each other. During the folding process, the sliders 24 slide in the slide rails 25 to contract, realizing the displacement between the lifting main rod 21 and the lifting auxiliary rod 22.

One end of the synchronous belt 53 is clamped with a driven pulley 54. The middle part of the driven pulley 54 is fixedly connected with a gear 55 through a connecting rod. A toothed plate 56 is engaged with the outer wall of the gear 55. The toothed plate 56 is fixedly installed at the bottom of the translation platform 40. The connecting rod is rotatably connected to the working platform 30 through a bearing. When the translation platform 40 needs to be extended, the driving motor 51 is started. The driving motor 51 drives the driving pulley 52 to move. The driving pulley 52 drives the driven pulley 54 to move, thereby driving the gear 55 to move. The gear 55 engages the toothed plate 56 to push out the translation platform 40. A plurality of equally spaced pulleys 32 are also fixedly installed on the inner side wall of the working platform 30. A chute is formed on the side wall of the translation platform 40. The pulleys 32 are embedded in the chute to support the translation platform 40. The plurality of pulleys 32 can improve the stability of the translation platform 40.

[0046] As a preferred embodiment, on the basis of the above-described manner, further, the safety protection component 60 includes support plates 61 fixedly connected to the top of the working platform 30 and the top of the translation platform 40. The bottom of the side wall of the support plate 61 is fixedly connected with a sliding plate 62. A main protection fence 63 is slidably connected to the inner side wall of the sliding plate 62. The middle part and the end part of the main protection fence 63 are respectively rotatably connected with auxiliary protection fences 64. One end of the two auxiliary protection fences 64 located at both ends is rotatably connected to the support plate 61. When the translation platform 40 extends, the column protection fence 63 and the auxiliary protection fences 64 are pulled to be unfolded, thereby forming a protection net. A strip-shaped chute is formed in the middle of the sliding plate 62. A cylindrical slider is arranged at the end of the main protection fence 63. The cylindrical slider is slidably installed inside the strip-shaped chute. When folding or extending, the cylindrical slider slides in the sliding plate 62.

[0047] As a preferred embodiment, on the basis of the above-described manner, further, a clamping block 71 is arranged on the side wall of the working door 70. A clamping groove 72 is formed in the middle of the clamping block 71. The clamping block 71 is a magnet block. The support plate 61 is made of iron. A pin shaft seat 73 is also fixedly connected to the side wall of the support plate 61. A bolt 74 is slidably connected to the inner side wall of the pin shaft seat 73. A spring 75 is fixedly connected between the bolt 74 and the pin shaft seat 73. The bolt 74 is adapted to the clamping groove 72. When the clamping block 71 approaches the bolt 74, it will push the bolt 74 upward to compress the spring 75. When the bolt 74 is aligned with the clamping groove 72, the bolt 74 is automatically inserted into the clamping groove 72 under the push of the spring 75 to complete the fixation of the clamping block 71.

[0048] Specifically, when the aerial work safety platform for bridge construction is in operation / use: the hydraulic push rod 26 extends to push the main lifting rod 21 and the auxiliary lifting rod 22 to fold with each other, thereby driving the work platform to move upward and pushing the staff to the construction area. Since both ends of the hydraulic push rod 26 are rotatably connected, the angle can be adjusted during the telescopic process of the hydraulic push rod 26. When the construction workers need to work closely, the drive motor 51 is started. The drive motor 51 drives the drive pulley 52 to rotate, thereby driving the driven pulley 54 through the synchronous belt 53. The driven pulley 54 drives the gear 55 to rotate and engage with the toothed plate 56 to push the translation platform 40 to the construction area. At the same time, the safety protection component 60 extends with the movement of the translation platform 40 to protect the personnel. When personnel need to get on and off, the bolt 74 is pulled upward to compress the spring 75, and at this time, the operation door 70 can be opened. When closing, the latch 71 can adsorb the support plate 61. When fitting the support plate 61, the latch 71 jacks up the bolt 74. When the bolt 74 aligns with the card slot 72, the spring 75 automatically pushes the bolt 74 to achieve plug-in fixation. The top of the latch 71 has an inclined contact surface, and the bottom of the bolt 74 is spherical.
