[0002] Construction elevators are also called construction elevator platforms for buildings. They can also be called outdoor elevators or construction site lifting cages. Construction elevators are mainly used in various types of high-rise and super-high-rise buildings in cities. The connection device between the construction elevator and the unloading platform is a device used to connect the construction elevator and the unloading platform. In construction, due to the need to transport materials and workers on different floors, construction elevators are widely used, and the unloading platform is used to safely unload construction waste, materials, etc. from high places to the ground. In order to effectively and safely connect these two devices, it is usually necessary to design and install a special connection device.

[0003] Currently, the existing devices for connecting construction elevators and unloading platforms on the market have the following disadvantages:

[0004] (1) There is a gap between the existing connection device and the elevator, and there is a lack of protection around it, which reduces the safety of construction workers when using the connection device;

[0005] (2) The existing connection device is usually a platform temporarily built at the elevator exit of the construction floor, which is not convenient for moving up and down with the elevator, reducing the convenience of using the connection platform. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a connection device between an external construction elevator and a discharge platform.

[0007] The utility model is implemented by the following technical solutions: a device for connecting an external construction elevator and an unloading platform, comprising a construction elevator platform, a surface of the construction elevator platform fixedly connected to a rotating shaft, a surface of the rotating shaft rotatably connected to a pedal, a top edge of the pedal fixedly connected to a telescopic component, a top of the telescopic component fixedly connected to a handrail, and a limiting component rotatably connected to the edge of one side of the construction elevator platform.

[0010] As a further improvement of the above solution, the limiting component includes a rotating disk rotatably connected to the edge of one side of the construction elevator platform, a handle is fixedly connected to one side of the rotating disk, and a limiting plate is fixedly connected to the other end of the rotating disk.

[0011] Through the above technical solution and the provision of the handle, the purpose of facilitating the rotation of the rotating disk is achieved.

[0012] As a further improvement of the above solution, a fixing plate is fixedly connected to the edge of the bottom of the pedal, and the bottom of the fixing plate is provided with anti-slip grooves.

[0013] Through the above technical solution, by setting the fixing plate, the pedal can be hooked on the raised structure of the building through the fixing plate, thereby improving the connection stability between the pedal and the building.

[0014] As a further improvement of the above solution, a B telescopic rod is fixedly connected to the edge of the bottom of the armrest, a B telescopic cylinder is slidably connected to the surface of the B telescopic rod, and a pedal is fixedly connected to the bottom of the B telescopic cylinder.

[0017] Through the above technical solution, the purpose of preventing the threaded rod from falling off during the rotation process is achieved by arranging the fixing ring and the threaded barrel.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model provides a telescopic component. When the construction worker uses the connection device to unload, the construction worker rotates the handle to screw the threaded rod outward until it is disengaged from the telescopic rod A, thereby canceling the restriction on the telescopic rod A so that the telescopic rod A can slide inside the telescopic cylinder A. The construction worker can then pull the handrail outward to slide the telescopic rod A and increase the height of the handrail. When the handrail is at a suitable height, the construction worker can cancel the restriction on the pedal through the restriction component, so that the pedal is flipped to one end to overlap the building layer and connect the construction elevator platform with the unloading platform, thereby making the connection device and the elevator platform tightly connected and protecting both sides of the connection device, thereby improving the safety of the construction worker when using the connection device.

[0020] The utility model provides a limiting component. Before the construction worker moves up and down through the construction elevator, he pulls the handrail to drive the pedal to flip to the entrance and exit of the closed construction elevator platform, and then retracts the handrail through the telescopic component to reduce the elevator platform space occupied by the handrail. Then the construction worker can rotate the handle to make the rotating disk drive the limiting plate to rotate, so that the limiting plate clamps the two sides of the pedal to limit the rotation of the pedal, so that the connecting device can move up and down together with the elevator, thereby improving the convenience of using the connecting platform.

DETAILED DESCRIPTION

[0027] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-4, a connection device between a construction elevator and an unloading platform of the present embodiment includes a construction elevator platform 1, a rotating shaft 2 is fixedly connected to the surface of the construction elevator platform 1, a pedal 3 is rotatably connected to the surface of the rotating shaft 2, and a telescopic component 4 is fixedly connected to the edge of the top of the pedal 3. By setting the telescopic component 4, when the construction personnel use the connection device to unload, they rotate the rotating handle 404 to screw the threaded rod 403 outward until it is disengaged from the A telescopic rod 402, and the restriction on the A telescopic rod 402 is cancelled so that the A telescopic rod 402 can slide inside the A telescopic cylinder 401, and then the construction personnel can pull the handrail 5 outward to slide the A telescopic rod 402 to increase the height of the handrail 5. When the handrail 5 is at a suitable height, the construction personnel can cancel the restriction on the pedal 3 through the restriction component 6, so that the pedal 3 is flipped to one end to overlap with the building layer, and the construction elevator platform 1 is unloaded. The lifting device is connected to the unloading platform, so that the connection device and the elevator platform are tightly connected and both sides of the connection device are protected, which improves the safety of construction workers when using the connection device. The top of the telescopic component 4 is fixedly connected to the handrail 5, and the edge of one side of the construction elevator platform 1 is rotatably connected to the limiting component 6. By setting the limiting component 6, before the construction worker moves up and down through the construction elevator, he pulls the handrail 5 to drive the pedal 3 to flip to the entrance and exit of the closed construction elevator platform 1, and then retracts the handrail 5 through the telescopic component 4 to reduce the elevator platform space occupied by the handrail 5. Then the construction worker can rotate the handle 602 to make the rotating disk 601 drive the limiting plate 603 to rotate, so that the limiting plate 603 is clamped on both sides of the pedal 3 to limit the rotation of the pedal 3, so that the connection device can move up and down together with the elevator, thereby improving the convenience of using the connection platform;

[0030] The telescopic assembly 4 includes a telescopic cylinder A 401 fixedly connected to the edge of the top of the pedal 3, a telescopic rod A 402 sliding inside the telescopic cylinder A 401, a threaded rod 403 threadedly connected to one side of the telescopic cylinder A 401, a threaded hole arranged in a path array on one side of the telescopic rod A 402, the telescopic rod A 402 being threadedly connected to the inside of the threaded hole, one end of the threaded rod 403 fixedly connected to a rotating handle 404, and the top of the telescopic rod A 402 fixedly connected to the handrail 5. The provision of the rotating handle 404 facilitates the rotation of the threaded rod 403.

[0031] The limiting assembly 6 includes a rotating disk 601 rotatably connected to the edge of one side of the construction elevator platform 1, a handle 602 fixedly connected to one side of the rotating disk 601, and a limiting plate 603 fixedly connected to the other end of the rotating disk 601. The setting of the handle 602 facilitates the rotation of the rotating disk 601.

[0032] A fixing plate 7 is fixedly connected to the edge of the bottom of the pedal 3. The bottom of the fixing plate 7 is provided with anti-slip grooves. Through the setting of the fixing plate 7, the pedal 3 can be hooked on the raised structure of the building through the fixing plate 7, thereby improving the connection stability between the pedal 3 and the building;

[0033] The bottom edge of the armrest 5 is fixedly connected to a telescopic rod B 8, the surface of the telescopic rod B 8 is slidably connected to a telescopic cylinder B 9, and the bottom of the telescopic cylinder B 9 is fixedly connected to the pedal 3. The arrangement of the telescopic rod B 8 and the telescopic cylinder B 9 achieves the purpose of improving the overall stability of the armrest 5;

[0034] A fixing ring 10 is fixedly connected to one side of the telescopic cylinder A 401, and a threaded cylinder 11 is fixedly connected to the interior of the fixing ring 10. The interior of the threaded cylinder 11 is threadedly connected to the threaded rod 403. The arrangement of the fixing ring 10 and the threaded cylinder 11 prevents the threaded rod 403 from falling off during rotation.

[0035] The implementation principle of the connection device between a construction elevator and an unloading platform in the embodiment of the present application is as follows: before the construction worker moves up and down by the construction elevator, he pulls the handrail 5 to drive the pedal 3 to flip to the entrance and exit of the closed construction elevator platform 1, and then retracts the handrail 5 through the telescopic component 4 to reduce the elevator platform space occupied by the handrail 5. Then the construction worker can rotate the handle 602 to make the rotating disk 601 drive the limiting plate 603 to rotate, so that the limiting plate 603 is stuck on both sides of the pedal 3 to limit the rotation of the pedal 3, so that the connection device can move up and down together with the elevator, and the construction worker can move up and down together with the elevator. When the workers use the connection device to unload, they rotate the handle 404 to screw the threaded rod 403 outward until it is disengaged from the A telescopic rod 402, thereby removing the restriction on the A telescopic rod 402 and allowing the A telescopic rod 402 to slide inside the A telescopic cylinder 401. Then, the construction workers can pull the handrail 5 outward to slide the A telescopic rod 402 and increase the height of the handrail 5. When the handrail 5 is at a suitable height, the construction workers can remove the restriction on the pedal 3 through the restriction component 6, so that the pedal 3 is flipped to one end to overlap with the building layer, thereby connecting the construction elevator platform 1 with the unloading platform.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
