Abstract
Description
Technical Field
[0001] The utility model relates to an anti-collision sliding door structure for a construction elevator, belonging to the technical field of elevators. Background Art
[0002] Construction elevators are also called construction elevators for buildings. They can also be called outdoor elevators and construction site hoist cages. Construction elevators are mainly used in various types of high-rise and super-high-rise buildings in cities, because such building heights are very difficult to complete using crisscross frames and gantry frames. Construction elevators are manned and cargo-carrying construction machinery frequently used in construction. They are mainly used for the interior and exterior decoration of high-rise buildings, bridges, chimneys and other construction. Due to its unique box structure, construction workers can ride comfortably and safely. Construction elevators are usually used in conjunction with tower cranes on construction sites.
[0003] In recent years, electric power-assisted bicycles have been widely used on construction sites, especially in mud and water teams. After the electric power-assisted bicycles entered the construction elevator, accidents occurred frequently due to workers' misoperation, causing the electric power-assisted bicycles to rush out of the construction elevator. Utility Model Content
[0004] In order to solve the above problems existing in the prior art, the utility model provides an anti-collision sliding door structure for a construction elevator.
[0005] The technical solution of the utility model is as follows:
[0006] A collision-proof sliding door structure for a construction elevator comprises a construction elevator car, a side sliding door is slidingly arranged on the front side of the construction elevator car, a linkage slide rail is fixedly arranged on the side sliding door, a slide groove is provided on the linkage slide rail, an anti-collision rocker arm is rotatably installed on the front side of the bottom face of the inner cavity of the construction elevator car, a sliding pin is arranged on the anti-collision rocker arm, the sliding pin is embedded in the slide groove of the linkage slide rail and is slidably installed therewith, a U-shaped limit seat is fixedly arranged on the front side of the top face of the inner cavity of the construction elevator car, and after the side sliding door is closed, the anti-collision rocker arm is driven to swing until the swinging end of the anti-collision rocker arm is engaged with the inner cavity of the U-shaped limit seat.
[0007] Preferably, the rotating end of the anti-collision rocker arm is hingedly mounted on an articulated seat, and the articulated seat is predetermined to be mounted on the front side of the bottom surface of the inner cavity of the construction elevator car.
[0008] Preferably, the front side of the construction elevator car is provided with door slide rails distributed up and down, and the upper and lower ends of the side sliding door are provided with U-shaped limit seats that slide with the door slide rails.
[0009] Preferably, the side sliding door comprises a frame part and a door panel part, and the frame part and the door panel part are fixedly welded.
[0010] Preferably, a limit stopper is fixedly provided on one side of the side sliding door.
[0011] The utility model arranges the side-pushing door on the front side of the construction elevator car into a side-pushing structure, and arranges an anti-collision swing arm on the inner side of the side-pushing door. The anti-collision swing arm is linked with the side-pushing door. When the side-pushing door is opened, the anti-collision swing arm lies flat to make space for people and goods to pass. When the side-pushing door is closed, the anti-collision swing arm swings and stands up and engages with the U-shaped limit seat on the top of the construction elevator car. The device adopts a linkage structure to combine the locking of the anti-collision swing arm with the side-pushing door to realize follow-up action, which can prevent the operator from neglecting to implement anti-collision measures and causing safety accidents, thereby playing a safety protection role.

[0013] Figure 2 This is a schematic diagram of the rear structure of the utility model;
[0014] Figure 3 It is a schematic diagram of the front structure of the utility model. DETAILED DESCRIPTION
[0015] 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 of 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.
[0016] Example:
[0017] See also Figure 1-3 A collision-proof sliding door structure for a construction elevator comprises a construction elevator car 10. The front side of the construction elevator car 10 is an entrance and exit for people and goods. A side sliding door 20 is slidingly arranged on the front side of the construction elevator car 10. The side sliding door 20 can be opened and closed by pushing and pulling sideways. The side sliding door 20 comprises a frame part 22 and a door panel 23. The frame part 22 and the door panel 23 are fixedly welded.
[0018] Specifically, the front side of the construction elevator car 10 is provided with a door slide rail 80 distributed up and down, and the upper and lower ends of the side push-pull door 20 are provided with a U-shaped limit seat 21, and the U-shaped limit seats 21 on the upper and lower sides are respectively engaged with the door slide rails 80 on the upper and lower sides to achieve sliding matching installation.
[0019] Furthermore, in order to restrict and prevent the side push-pull door 20 from pushing and pulling, a limit stopper 24 is fixedly provided on one side of the side push-pull door 20. When the side push-pull door 20 is opened to the limit position, the limit stopper 24 blocks the right inner wall of the construction elevator car 10. When the side push-pull door 20 is closed to the fully closed position, the limit stopper 24 blocks the left inner wall of the construction elevator car 10.
[0020] A linkage slide rail 30 is fixedly arranged on the side push-pull door 20, and a slide groove 31 is arranged on the linkage slide rail 30. A hinge seat 70 is fixedly arranged on the front side of the inner bottom of the construction elevator car 10, and an anti-collision swing rod 40 is rotatably arranged on the hinge seat 70. The anti-collision swing rod 40 can rotate around the hinge seat 70 under the driving action of an external force.
[0021] The anti-collision swing bar 40 is provided with a sliding pin 50, which is embedded in the slide groove 31 of the linkage slide rail 30 and slidably installed therewith. When the side sliding door 20 moves left and right, the linkage slide rail 30 drives the sliding pin 50 to move in its slide groove 31, thereby driving the anti-collision swing bar 40 to swing accordingly;
[0022] A U-shaped limit seat 60 is fixedly provided on the front side of the inner top surface of the inner cavity of the construction elevator car 10. After the side-pushing car door 20 is closed, the anti-collision rocker arm 40 is driven to swing until the swinging end of the anti-collision rocker arm 40 engages with the inner cavity of the U-shaped limit seat 60, so that after the side-pushing car door 20 is closed, the upper and lower ends of the anti-collision rocker arm 40 have fixed structures to ensure the supporting strength of the two ends of the anti-collision rocker arm 40.
[0023] The working principle of this utility model:
[0024] When the side-pushing door 20 is opened, the anti-collision rocker arm 40 lies flat to make room for people and goods to pass; when the side-pushing door 20 is closed, the anti-collision rocker arm 40 swings upright and engages with the U-shaped limit seat 60 on the top of the construction elevator car 10. The device adopts a linkage structure to combine the locking of the anti-collision rocker arm 40 with the side-pushing door 20 to achieve follow-up action, which can prevent the operator from neglecting to implement anti-collision measures and causing safety accidents, thereby playing a safety protection role.
[0025] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
