[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-2 The industrial lifting door shown in the figure includes a lifting door body 1 and a door frame 2, the lifting door body 1 is movably arranged inside the door frame 2, an anti-falling structure 3 is arranged between the lifting door body 1 and the door frame 2, and the anti-falling structure 3 includes a limit rod 301, a limit block 302 and a movable component, the limit rod 301 is fixedly arranged on the side of the lifting door body 1, the end face of the limit rod 301 away from the lifting door body 1 is in an arc shape, the limit blocks 302 are fixedly arranged at equal intervals in the inner cavity of the door frame 2, the limit blocks 302 are in a right-angle cone shape, and the end of the limit rod 301 away from the lifting door body 1 extends to two adjacent The right-angled side of the limit block 302 opposite to the limit rod 301 faces upward. When the lifting door body 1 is rising, the position is usually moved by the cooperation of a wire rope and a pulley rail. During the rising process of the lifting door body 1, due to the weight of the lifting door body 1 and the pulling of the rope, the lifting door body 1 is in danger of falling during the rising process. Therefore, the limit rods 301 are fixedly arranged at the bottom of both sides of the lifting door body 1, so that the limit rods 301 can move upward with the rising of the lifting door body 1, and the limit rods 301 are fixedly arranged at the bottom of both sides of the lifting door body 1. The end of 01 facing the limit block 302 is set in an arc shape, and the setting of the bevel of the limit block 302 is coordinated, so that when the limit rod 301 moves upward with the lifting door body 1, it can generate an extrusion force on the bevel of the limit block 302, so that the limit block 302 moves away from the limit rod 301 after being squeezed, so that the limit rod 301 can move upward stably. Because the right-angled side of the limit block 302 close to the position of the limit rod 301 faces upward, therefore, when the limit rod 301 moves along the bevel of the limit block 302 to the upper side of the limit block 302 After the door 301 is lowered, the right-angled side of the limit block 302 can be used to prevent the limit rod 301 from moving downward, so that when the limit rod 301 is in a stable state, the limit rod 301 can only move upward. In summary, when the door body 1 moves upward, the limit rod 301 can be driven to move upward synchronously. During the upward movement of the limit rod 301, the setting of the limit block 302 is used to ensure that the limit rod 301 only rises and does not move downward, thereby preventing the door body 1 from falling during the upward movement, and effectively improving the stability and safety of the upward movement of the door body 1.

[0026] Furthermore, a movable component is arranged between the limit blocks 302, and the movable component is used for moving the position of the limit blocks 302 and the limit rod 301. The movable component includes a reset belt 303, and the reset belt 303 is movably arranged in the inner cavity of the door frame 2. The inner wall of the reset belt 303 is fixedly provided with an elastic layer 304 for buffering. The reset belt 303 remains in a stable state during the upward movement of the limit rod 301, and when the lifting door body 1 is lowered, the limit block 302 can be driven to change its position synchronously by the rotating reset belt 303, so that the limit rod 301 can be smoothly lowered with the descent of the lifting door body 1, and at the same time, it can also avoid the dangerous phenomenon caused by the lifting door body 1 descending too quickly, and the reset belt 303 drives the limit block 302 to change its position clockwise. The elastic layer 304 is any one of elastic rubber or elastic silicone. The elastic layer 304 is fixedly arranged with the reset belt 303 and the conveyor belt 401, so that the reset belt 303 and the conveyor belt 401 are relatively fixed, so that the reset belt 303 can be driven to rotate synchronously while the conveyor belt 401 rotates. At the same time, the setting of the elastic layer 304 strengthens the elasticity of the reset belt 303, so that when the limit block 302 is squeezed by the limit rod 301, the elasticity of the elastic layer 304 can be used to produce a change in position, thereby providing effective support for the use of the limit rod 301 and the limit block 302.

[0027] Furthermore, a driving structure 4 is provided inside the reset belt 303, and the driving structure 4 includes a conveyor belt 401 and a transmission wheel 402. The conveyor belt 401 is fixedly arranged with the elastic layer 304, and the transmission wheel 402 is symmetrically arranged at the end of the inner cavity of the conveyor belt 401. An axle rod is fixedly arranged in the middle of the transmission wheel 402, and the axle rod is rotatably interlaced with the inner wall of the door frame 2. The transmission wheel 402 is meshed with the inner wall of the conveyor belt 401, and the rotation of the transmission wheel 402 can drive the conveyor belt 401 to rotate. The driving structure 4 also includes a connecting groove 403 and a driving rod 404. The connecting groove 403 is opened at the end face of the transmission wheel 402 away from the axle rod, and the driving rod 404 is interlaced in the inner cavity of the connecting groove 403. The end of the driving rod 404 away from the connecting groove 403 passes through the outer wall of the door frame 2 and extends to the outside. The connecting groove 403 is rectangular, and the end of the driving rod 404 interlaced with the connecting groove 403 is rectangular. The driving rod 404 is T-shaped, and the rectangular setting of the connecting groove 403 cooperates with the setting of the shape of the end of the driving rod 404 close to the connecting groove 403, so that the driving rod 404 can be inserted and connected with the connecting groove 403, and the connecting groove 403 and the transmission wheel 402 can be driven to rotate while rotating the driving rod 404, so as to provide a rotational force for the conveyor belt 401. The driving rod 404 penetrates the door frame 2 and is rotated and inserted with the door frame 2. The driving rod 404 is T-shaped away from the end of the connecting groove 403, which provides convenience for the operator to rotate the driving rod 404, and the driving rod 404 can be rotated manually or by installing a driving motor. The specific rotation method can be selected according to the use requirements. In summary, the rotation of the driving rod 404 can drive the transmission wheel 402 to rotate, thereby driving the conveyor belt 401 and the reset belt 303 to rotate, and then the limit block 302 can be driven to change its position.
