Description

Technical Field

[0001] The utility model relates to the field of elevator protection, in particular to an anti-impact floor door device for an elevator. Background Art

[0002] At present, a Chinese utility model with the announcement number CN220165565U discloses an anti-impact floor door device for a mine elevator, which relates to the technical field of elevators, including a car, two doors are slidably provided on the car, and a group of vertical beams are respectively provided on the outside of the car corresponding to the two doors, each group of vertical beams is provided with a plurality of beams, and the vertical beams are provided vertically and cooperate with the outer wall of the car for sliding, and each group of vertical beams is connected by a steel cable, and the vertical beams near the middle of the car are fixedly connected to the door, and the vertical beams near the edge of the car are connected to the car by a steel cable. When the door is closed, the utility model pulls each vertical beam toward the middle, so that the multiple vertical beams form a grid-like barrier outside the door of the car, and then cooperates with the door to form a double-layer door structure, which effectively protects the car, and because the vertical beams are dispersed, the door is still very flexible to open and close, and the use of protective materials can also be reduced;

[0003] Although the existing protective structure can add a guardrail in front of the elevator car to block objects that collide with the elevator car in advance, there are still other problems during use, such as poor impact resistance. Since the guardrail is rigidly connected and fixed, when the guardrail cannot move backward to release force after being hit, it is easy to break and deform after the impact is too large, the safety is low, and it is not convenient to replace a single guard beam. In order to save materials and reduce weight, the frame does not use an integral baffle, but uses multiple guard beams for protection. The guard beams are fixed to the frame by welding. When the guard beam breaks and needs to be replaced, the welding point can only be cracked first, and then the new guard beam is put in and re-welded, which increases the workload of personnel and has low practicality. In order to solve the above-mentioned problems, we propose an anti-impact floor door device for elevators. Utility Model Content

[0004] The utility model aims to provide an anti-impact floor door device for an elevator, which solves the problem that the existing protective floor door device has a poor anti-impact effect and is inconvenient to replace the stop beam.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-impact floor door device for an elevator, comprising a first column, a second column is arranged on one side of the first column, an outer frame is hinged on one side of the first column through a hinge, an inner frame is arranged inside the outer frame, a fixing spring is bolted between the back side of the inner frame and the outer frame through a spring fixing sheet, a damper is installed between the back side of the inner frame and the outer frame, a stop beam is arranged inside the inner frame, a slot for use with the stop beam is provided on the front side of the inner frame, a fixing bolt is penetrated through the front side of the stop beam, and a threaded hole for use with the fixing bolt is provided inside the slot.

[0006] The adoption of the above technical solution can achieve good impact resistance, and can transfer part of the force to be unloaded at the moment of impact, thereby reducing the breakage and deformation caused by excessive impact force at the moment of impact. It has high safety and can facilitate the replacement of the guard beam. The operation is simple and labor-saving, which improves the work efficiency of personnel and is highly practical.

[0007] The utility model is further configured as follows: a mounting plate is welded to the bottom of each of the first column and the second column, and a mounting hole is opened on the top of the mounting plate.

[0008] By adopting the above technical solution, through the provision of the mounting plate and the mounting holes, it is convenient for personnel to fix the first column and the second column with screws.

[0009] The utility model is further configured as follows: a fixing plate is welded on one side of the outer frame, a limiting pin is penetrated through the top of the fixing plate, and a limiting groove used in conjunction with the limiting pin is opened on the top of the second column.

[0010] By adopting the above technical solution, the outer frame can be limited by setting the fixing plate, the limiting pin and the limiting groove to prevent the outer frame from shifting after rotation and closure.

[0011] The utility model is further configured as follows: the fixing spring is made of carbon spring steel.

[0012] By adopting the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0013] The utility model is further configured as follows: surfaces of the first column, the second column, the outer frame, the inner frame and the guard beam are all coated with anti-corrosion paint.

[0014] By adopting the above technical solution and setting the anti-corrosion coating, the anti-corrosion effect of the surfaces of the first column, the second column, the outer frame, the inner frame and the guard beam can be improved, thereby extending their service life.

[0015] The utility model is further configured as follows: the fixing bolt is made of stainless steel.

[0016] By adopting the above technical solution, the fixing bolt has the characteristics of high strength, low density and excellent corrosion resistance.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model fixes the first column and the second column in front of the elevator car with screws. When an object rolls into the car, it will first hit the inner frame and the stop beam. The inner frame or the stop beam will move the stop beam backward under force. When the stop beam moves backward, it will press the fixed spring and the damper. Since the fixed spring has elasticity, it will absorb the force when it is compressed and in a contraction and energy storage state, so as to achieve good impact resistance. It can move backward at the moment of impact to unload part of the force, reduce the breakage and deformation caused by excessive impact force at the moment of impact, and has high safety.

[0019] 2. When the guard beam is damaged, the utility model first uses tools to remove the two fixing bolts on the damaged guard beam. After the fixing bolts are removed, the guard beam is released. Then the guard beam is pulled forward out of the inner frame, and a new guard beam is put into the replacement position. Finally, the fixing bolts are reinserted and tightened. The guard beam can be easily replaced, the operation is simple and labor-saving, the work efficiency of the personnel is improved, and the practicability is high. BRIEF DESCRIPTION OF THE DRAWINGS
