Description

Technical Field

[0001] The utility model relates to the field of construction elevator cage door protection, in particular to a single-door anti-collision device for a construction elevator cage door. Background Art

[0002] The anti-collision safety device for the door of the construction hoist cage is a safety anti-collision protection device for the door of the construction hoist bridge box. It is also a protection device to prevent the door from being damaged and causing safety accidents when transporting goods in the bridge box. At present, the commonly used methods are to use manual chain when pushing the goods into the cage or use a square tube with one end fixed and manually pull it down to prevent the goods from hitting the door. This method is not automatic, and sometimes workers will miss or misoperate when using it, which will occasionally damage the door and cause the goods or people to fall out of the cage and cause safety accidents or hidden dangers. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a single-door anti-collision device for a construction elevator cage, which does not require manual operation, has low safety hazards and plays a good protective role on the cage door.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a single-door anti-collision device for a construction elevator cage, comprising an anti-collision bar arranged on the cage door and two blocking seats arranged on the elevator floor, the anti-collision bar comprising a cross bar and connecting rods arranged at both ends of the cross bar, and the connecting rod is fixed on the cage door; the two blocking seats are correspondingly arranged below the two ends of the cross bar, the blocking seats are H-shaped, and the blocking seats comprise two fixed columns and a limiting rod arranged between the two fixed columns; the two fixed columns are fixed on the elevator floor; a limiting groove for accommodating the cross bar is formed between the two fixed columns and the limiting rod. The working principle of the utility model is as follows: when the anti-collision bar follows the cage door to descend and contacts the limit column, the cage door stops and cannot descend. At this time, the vertical distance between the bottom of the cage door and the elevator floor is a safe distance; when hit by goods or objects, the anti-collision bar will play a certain protective role for the cage door. When the anti-collision bar is located in the limit groove, the blocking seat will decompose and buffer part of the impact force, reduce the impact force transmitted to the cage door by the anti-collision bar, and reduce the force transmitted to the cage door.

[0005] As an improvement, one end of the connecting rod is welded to the door frame of the cage door, and the other end of the connecting rod is welded and fixed to the cross bar; the cross bar is a round tube.

[0006] As an improvement, the fixing column is a square tube, the fixing column is perpendicular to the ground, and a drainage outlet is provided on one side of the lower end of the fixing column; the limiting rod is parallel to the ground.

[0007] As an improvement, after the cross bar contacts the limit rod, a gap is left between the bottom of the cage door and the elevator bottom plate.

[0008] The beneficial effects of the utility model are as follows: the utility model has a simple and firm structure, is easy to produce, and has a low manufacturing cost. By installing an anti-collision bar on the cage door and installing a blocking seat compatible with the anti-collision bar on the elevator floor, the cage door can be protected to a certain extent. The device does not require manual operation, and the anti-collision bar will move in conjunction with the cage door, thereby avoiding the occurrence of safety hazards caused by human negligence. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a side view of the utility model.

[0010] Figure 2 It is a front view of the utility model.

[0011] Figure 3 It is a top view of the utility model.

[0012] Explanation of the numbers in the figure: 1. Cage door; 2. Cross bar; 21. Connecting rod; 3. Blocking seat; 31. Fixed column; 32. Limit rod; 4. Elevator bottom plate. Implementation

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings of the specification;

[0014] like Figures 1 to 3 As shown, a single-door anti-collision device for a construction elevator cage includes an anti-collision bar arranged on the cage door 1 and two blocking seats 3 arranged on the elevator floor 4, the anti-collision bar includes a cross bar 2 and connecting rods 21 arranged at both ends of the cross bar 2, the connecting rod 21 is fixed to the cage door 1 by welding, and the connection and the cross bar 2 are fixed by welding; the two blocking seats 3 are correspondingly arranged below the two ends of the cross bar 2, the blocking seats 3 are H-shaped, the blocking seats 3 include two fixed columns 31 and a limiting rod 32 arranged between the two fixed columns 31, the two fixed columns 31 are fixed to the elevator floor 4 by welding, and a limiting groove for accommodating the cross bar 2 is formed between the two fixed columns 31 and the limiting rod 32. The anti-collision bar can play a certain protective role for the cage door 1. When the cage door 1 descends and the cross bar 2 is in the limit groove, when the anti-collision bar is hit by goods or objects, the blocking seat 3 will also decompose and buffer the impact force on the anti-collision bar, thereby reducing the impact force finally transmitted to the cage door 1.

[0015] like Figures 1 to 3As shown, one end of the connecting rod 21 is welded to the door frame of the cage door 1, and the other end of the connecting rod 21 is welded and fixed to the cross bar 2; so that the force transmitted to the cage door 1 mainly acts on the door frame, and has little effect on the main body of the cage door 1. The cross bar 2 is a round tube, and the fixed column 31 is a square tube, with low manufacturing cost and low difficulty in obtaining materials. The fixed column 31 is perpendicular to the ground, and the limit rod 32 is parallel to the ground; a drainage port is provided on one side of the lower end of the fixed column 31; since the fixed column 31 is a square tube, the drainage port can prevent water from accumulating inside the fixed column 31. After the cross bar 2 contacts the limit rod 32, a gap is left between the bottom of the cage door 1 and the elevator bottom plate 4; during the installation process, the constructor sets a safe distance and adjusts the appropriate distance so that the cross bar 2 can smoothly enter the limit groove formed by the blocking seat 3, and when the anti-collision bar on the cage door 1 contacts the limit rod 32, a safe distance is left between the bottom of the cage door 1 and the elevator bottom plate 4.

[0016] The use principle of the utility model: during the installation of the anti-collision bar and the blocking seat 3, first determine the safe height, and then install the connecting rod 21 and the limit column at the appropriate position; after the installation is completed, when the anti-collision bar follows the cage door 1 to descend and contacts the limit column, the cage door 1 stops and cannot descend. At this time, the vertical distance between the bottom of the cage door 1 and the elevator floor 4 is a safe distance; when hit by goods or objects, the blocking seat 3 will decompose and buffer the impact force exerted on the anti-collision bar, reduce the impact force transmitted to the cage door 1 by the anti-collision bar, and protect the cage door 1.
