Description

Technical Field

[0001] The utility model relates to the technical field of industrial lifting doors, in particular to a large industrial lifting door which is not easily deformed. Background Art

[0002] Large industrial lifting doors are one of the common equipment in industrial plants. They are used to separate the space inside and outside the plant to ensure the safety and stability of the production environment. Industrial lifting doors have the advantages of flexible installation, easy operation, and good anti-theft performance, and are therefore widely used in stores, garages, warehouses, and workshops.

[0003] In the prior art, traditional industrial plant lifting doors are mostly moved by a winch in conjunction with a wire rope during use. One end of the wire rope is wound around the winch. During winding, the end of the wire rope moves, thereby pulling the lifting door to move. At that time, this method had a major defect. If the winch was damaged or the wire rope broke, the lifting door would fall quickly due to lack of limit, which could easily cause danger. At the same time, the strong impact force could easily cause damage to the lifting door. Therefore, the utility model proposes a large industrial lifting door that is not easy to deform, so as to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a large-scale industrial lifting door which is not easy to deform. By setting a limiting mechanism and a clamping block, when the wire rope breaks and causes the door body to fall rapidly, a plurality of moving blocks break free from the elastic force of the spring and are thrown out, so that the moving blocks are clamped on the clamping blocks on both sides, thereby limiting the door body and preventing the door body from falling rapidly and causing danger.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A large industrial lifting door that is not easily deformed comprises a wall panel and a door body, wherein the wall panel is provided with a door hole that matches the door body, and two symmetrically arranged racks are fixedly connected to the side walls of the wall panel, and limiting grooves are provided on the side walls at opposite ends of the two racks, and the door body is slidably connected in the two limiting grooves, and a limiting mechanism for limiting the door body is provided on the side walls of the door body, and the limiting mechanism comprises two symmetrically arranged fixed blocks fixedly connected to the side walls of the door body, and a rotating rod is connected between the two fixed blocks for rotation, and both ends of the rotating rod are fixedly connected with a turntable, and the side walls of the two turntables are provided with four grooves that are circumferentially evenly spaced, and moving blocks are slidably connected in multiple grooves.

[0007] Preferably, the upper end of the wall panel is fixedly connected to a top plate, and the lower end of the wall panel is fixedly connected to a bottom plate.

[0008] Preferably, the plurality of moving blocks are elastically connected to the inner wall of the groove on the same side via a spring.

[0009] Preferably, the upper end of the bottom plate is fixedly connected to two symmetrically arranged fixing plates, the side walls of the wall plate and the two fixing plates are fixedly connected to blocks, and the multiple blocks in the same group are arranged at equal intervals.

[0010] Preferably, two symmetrically arranged gears are fixedly sleeved on the rotating rod, and the two gears are respectively meshed with racks on both sides.

[0011] Preferably, a winch is installed at the upper end of the top plate, a steel wire rope is wound around the winch, and the end of the steel wire rope is fixedly connected to the upper end of the door body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting a limit mechanism and a card block, when the wire rope breaks and causes the door body to fall rapidly, the door body moves downward, driving the rotating rod to move downward, so that the gear moves on the rack. Under the action of the rack, the gear rotates rapidly, thereby driving the rotating rod and the turntables on both sides to rotate rapidly. Under the action of centrifugal force, multiple moving blocks break free from the spring elastic force and are thrown out, so that the moving blocks are stuck on the blocks on both sides, thereby limiting the door body and preventing the door body from falling rapidly and causing danger.

[0014] 2. By setting the limit groove and the limit mechanism, the limit groove can realize the limit guiding of the door body. When falling occurs, the moving block is stuck on the card block. At this time, the limit of the door body is completed and the wire rope can be repaired. After the repair is completed, the winch can be used to pull the door body up a short distance. Under the action of the spring, the moving block is reset and the door body can be lowered. BRIEF DESCRIPTION OF THE DRAWINGS
