Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an anti-collision device for a construction elevator. Background Art
[0002] Housing construction projects refer to various types of housing buildings and their ancillary facilities and the supporting lines, pipelines, equipment installation projects and indoor and outdoor decoration projects. "Housing construction" refers to projects with roofs, beams, columns, walls, foundations and the ability to form internal spaces to meet people's needs for production, living, learning, public activities, etc. Housing construction projects are generally referred to as construction projects, which refer to the various technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures, as well as the completed engineering entities.
[0003] During the construction of housing projects, the SC200 / 200 construction hoist is an ideal vertical transportation equipment for construction sites and is increasingly used. The SC200 / 200 is a double-cage rack-and-pinion construction hoist without counterweight. The rated load of each cage is 2000KG. The cage uses a drawer door and moves up and down by sliding on a pulley.
[0004] At present, combined with the on-site usage situation, the sliding door is prone to derailment when hit by external objects, resulting in the risk of the sliding door falling, posing certain safety hazards and causing inconvenience in construction. Therefore, an anti-collision device for a construction elevator is proposed to solve the above-mentioned problems. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides an anti-collision device for a construction elevator, which has the advantages of preventing collision and falling, and solves the problem that the sliding door is prone to derailment when hit by foreign objects, resulting in the risk of the sliding door falling, posing certain safety hazards and causing construction inconvenience.
[0006] To achieve the above object, the utility model provides the following technical solution: a construction elevator anti-collision device, comprising a cage, a drawer door is slidably installed on one side of the cage, and a protective component is arranged between the cage and the drawer door;
[0007] The protective component includes a rectangular steel pipe and a channel steel, the rectangular steel pipe is connected to the lower part of the sliding door, the channel steel is fixedly connected to the inner wall of the cage, the number of the channel steels is set to two, and the two channel steels are respectively arranged at both ends of the rectangular steel pipe.
[0008] Furthermore, connecting columns are fixedly welded on the outer wall of the drawing door, the number of the connecting columns is two, and the rectangular steel pipe is fixedly welded on the outer sides of the two connecting columns.
[0009] Furthermore, the two channel steels are respectively located on the left and right sides of the inner bottom wall of the cage.
[0010] Furthermore, the inner wall of the channel steel is adapted to the rectangular steel pipe.
[0011] Compared with the prior art, the utility model provides a construction elevator anti-collision device, which has the following beneficial effects:
[0012] The construction elevator anti-collision device can effectively improve the safety of the cage by installing a protective component at the bottom of the cage sliding door. First, the protective component can block the first wave of impact from the bottom to prevent heavy objects from directly causing damage to the door. Secondly, the protective component can effectively prevent the sliding door from falling downward after being damaged by a collision, reducing the risk of falling objects from a high altitude. The installation of the protective component is another guarantee for the safety of the cage sliding door, and has the advantages of simple construction and installation, economical and practical, and strong protection.

[0017] 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.
[0018] See also Figures 1 to 3The anti-collision device of the construction elevator in this embodiment includes a cage 1, a drawer door 2 is slidably installed on one side of the cage 1, a protective component is arranged between the cage 1 and the drawer door 2, and the protective component includes a rectangular steel pipe 4 and a channel steel 5, the rectangular steel pipe 4 is connected to the lower part of the drawer door 2, the channel steel 5 is fixedly connected to the inner wall of the cage 1, the number of the channel steel 5 is set to two, and the two channel steels 5 are respectively arranged at both ends of the rectangular steel pipe 4, wherein the inner wall of the channel steel 5 is adapted to the rectangular steel pipe 4, and the channel steel 5 is used to limit the rectangular steel pipe 4 to prevent the drawer door 2 from being derailed by collision with foreign objects, so as to avoid the risk of falling objects from high altitude, and the two channel steels 5 can play a role of stabilizing the position of the rectangular steel pipe 4, thereby improving the protective performance.
[0019] It should be noted that connecting columns 3 are fixedly welded on the outer wall of the sliding door 2, the number of connecting columns 3 is two, the rectangular steel pipe 4 is fixedly welded to the outside of the two connecting columns 3, and the two channel steels 5 are respectively located on the left and right sides of the inner bottom wall of the cage 1.
[0020] The working principle of the above embodiment is:
[0021] When the utility model is in use, before the construction elevator is operated, the sliding door 2 slides downward and closes, thereby driving the rectangular steel pipe 4 on the connecting column 3 to descend and get stuck between the two channel steels 5, thereby improving the anti-collision ability of the sliding door 2, and preventing the sliding door 2 from being derailed by collision with foreign objects through the connection of the rectangular steel pipe 4 and the channel steel 5, thereby avoiding the risk of falling objects from high altitude and loss of protection for people in the cage 1. At the same time, the rectangular steel pipe 4 and the channel steel 5 form a natural barrier on the bottom wall of the cage 1, thereby preventing most objects in the cage 1 from directly impacting the sliding door 2, thereby protecting the sliding door 2.
[0022] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects. It should be noted that in this article, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
