Description

Technical Field

[0001] This utility model belongs to the field of civil defense door installation technology, and in particular relates to a hoisting device for civil defense door installation. Background Technology

[0002] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. During inspection or maintenance, various lifting tools are used to lift equipment, workpieces, tools, materials, etc., to change their position. In civil defense projects, due to the small space, general crane equipment cannot be deployed, resulting in the use of small-volume, simple and crude small lifting devices for the installation of civil defense equipment. A type of lifting device for civil defense door installation is required.

[0003] Currently, Chinese patent CN210505314U discloses a hoisting device for installing civil defense equipment, including a base. An electric hydraulic jack is fixedly connected to the upper surface of the base. A fixing block is fixedly connected to the top of the electric hydraulic jack. A connecting cover is rotatably connected to the top of the fixing block via a first rolling bearing. A lifting rod and a support plate are fixedly connected to the upper surface of the connecting cover. A first and second fixed pulley are fixedly connected to the wall of the lifting rod. A drive motor and a U-shaped plate are fixedly connected to the upper surface of the support plate. Circular through holes are provided on both sides of the U-shaped plate. This invention effectively improves the mobility of the hoisting device, eliminating the need for manual handling, saving time and effort, reducing the workload for workers, improving the efficiency of civil defense equipment installation, and enhancing the stability of the hoisting device to prevent it from tipping over and damaging the civil defense equipment, ensuring the safety of hoisting the civil defense equipment, and avoiding unnecessary losses.

[0004] However, when the above-mentioned device is in use, it only relies on the hook to lift the door panel, which makes the door panel prone to sliding and falling, posing a potential safety hazard to the staff. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a hoisting device for installing air-raid shelter doors. Its advantages include: it can fix the door panel, thus ensuring the safety of workers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hoisting device for installing a civil defense door includes a hoist body, a cable body is fixedly installed on the top of the hoist body, a hook is fixedly connected to the end of the cable body, an adjustment mechanism is provided on the upper part of the hook, and a fixing mechanism is provided on the bottom of the adjustment mechanism.

[0008] The fixing mechanism includes a mounting plate fixedly connected to the cable body. Electric slide rails are provided on both sides of the bottom of the mounting plate. Electric sliders are slidably connected to both sides of the inner wall of the electric slide rails. The two electric sliders located at the same end move in opposite directions. A fixing plate is fixedly connected to the bottom of the electric slider. The fixing plate is distributed around the hook.

[0009] Through the above technical solution: In use, the starting cable body descends and the hook hooks the fixed position of the air-raid shelter door. The lifting ring that fixes the air-raid shelter door can squeeze the limiting rod and be located at the bottom of the hook. Starting the electric guide rail can move the electric slider. The position of the two electric guide blocks can be adjusted according to the length of the air-raid shelter door. Starting the electric slide rail can move the electric slider. The movement of the electric slider can bring the fixing plates closer to each other, and together with the clamping plate and clamping spring, the air-raid shelter door can be fixed. Therefore, the door panel can be fixed, achieving the effect of ensuring the safety of the staff.

[0010] The present invention is further configured such that a clamping plate is hinged to the top of the fixing plate, and a clamping spring is fixedly connected to one side of the clamping plate, and the clamping spring is fixed to the fixing plate.

[0011] Through the above technical solution, the clamping spring can apply pressure to the clamping plate, which can make the clamping plate securely fixed to the air defense door.

[0012] The present invention is further provided that an anti-slip pad is fixedly connected to one side of the clamping plate, and the anti-slip pad is made of rubber.

[0013] Through the above technical solutions, the anti-slip pads can increase the friction between the clamping plate and the air-raid shelter door, further stabilizing the air-raid shelter door.

[0014] The present invention is further configured such that the anti-slip pad has a double-layer cavity structure.

[0015] The above technical solution, with its double-layer cavity structure, increases the deformation capacity of the anti-slip pad, thus ensuring the stability of the air defense door.

[0016] The present invention is further configured such that the adjustment mechanism includes an electric guide rail fixedly connected to the bottom of the mounting plate, and electric guide blocks are slidably connected to both ends of the inner wall of the electric guide rail. The two electric guide blocks move in opposite directions, and the electric guide blocks are fixed to the electric guide rail.

[0017] Through the above technical solution: the electric guide block can slide in the inner wall of the electric guide rail, and the position of the fixing plate can be adjusted so that the clamping plate can come into contact with the air defense door.

[0018] The present invention is further configured such that a limiting rod is hinged to the top of the inner wall of one side of the hook, and the limiting rod rotates inside the hook.

[0019] Through the above technical solution: the setting of the limit rod allows the lifting ring of the air-raid shelter door to be hooked and rotated downwards. After the lifting ring is at the bottom of the hook, a certain limit operation can be performed on the lifting ring.

[0020] The present invention is further configured such that a limiting spring is fixedly connected to one side of the limiting rod, and the limiting spring is fixed to the hook.

[0021] Through the above technical solution, the setting of the limit spring can apply pressure to the limit rod after the lifting ring is placed, which can make the air defense door fixed and stable.

[0022] The present invention is further configured such that a limiting groove is provided on one side of the inner wall of the hook, and the inner wall of the limiting groove forms a sliding fit with the limiting rod.

[0023] Through the above technical solutions, the setting of the limiting groove can limit the upward rotation of the limiting rod, thus preventing the lifting ring and hook of the air defense door from separating.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The hoisting device for installing the air-raid shelter door uses an electric guide rail to move the electric slider. The positions of the two electric guide blocks can be adjusted according to the length of the air-raid shelter door. Activating the electric guide rail causes the electric slider to move, which brings the fixing plates closer together. Together with the clamping plate and clamping spring, the air-raid shelter door is fixed in place, thus ensuring the door panel is secure and protecting the safety of the staff.

[0026] 2. The hoisting device for installing the air-raid shelter door can be hooked and rotated downwards by a limit rod. After the hoisting ring is at the bottom of the hook, a certain limit operation can be performed on the hoisting ring.

[0027] 3. The hoisting device for installing the air-raid shelter door can apply pressure to the limit rod after the lifting ring is placed in the position of the limit spring, so that the air-raid shelter door can be fixed and stable. The limit groove can limit the upward rotation of the limit rod, which can prevent the lifting ring and hook of the air-raid shelter door from separating. Attached Figure Description
