Description
Technical Field
[0001] The utility model relates to the technical field of construction elevators, in particular to a construction elevator cage door anti-falling safety device. Background Art
[0002] Construction hoists are important equipment used for vertical transportation of personnel and materials during construction. They are usually installed on the exterior wall or internal shaft of a building, and are used to lift workers, equipment and construction materials to a specified height through a cage or platform driven by an electric motor. Construction hoists have the advantages of easy operation, high transportation efficiency, safety and reliability, and are widely used in the construction of high-rise buildings, bridges, towers and other engineering projects. The door of a construction hoist is an important part of ensuring safety, and its design directly affects the safety of personnel and materials and the convenience of operation.
[0003] The existing construction elevator doors have the following problems during operation: 1. When the construction elevator fails, the cage door will be completely relaxed without any protection measures; 2. When the construction elevator fails, the cage door will be completely locked and can only be opened after repair or restoration; 3. The construction elevator cage door is heavy and users cannot manually lift it all at once and escape. Utility Model Content
[0004] The utility model aims to provide a construction elevator cage door anti-fall safety device to solve the problems in the above-mentioned background technology that when the construction elevator fails, the cage door will be completely relaxed without any protective measures, the cage door will be completely locked when a failure occurs, and can only be opened after repair or restoration, and the construction elevator cage door is heavy and the user cannot manually lift it all at once and escape.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction elevator cage door anti-falling safety device, comprising a card block, a channel groove is opened on one side of the card block, and two shift blocks are arranged in the channel groove;
[0006] A sliding plate is slidably connected to the outer side of the clamping block, and the shifting block is fixedly connected to the sliding plate;
[0007] The channel groove and the two shifting blocks form an accommodating cavity which is wider at the bottom and narrower at the top, and a sliding clamping column is arranged in the accommodating cavity.
[0008] Preferably, the top width of the channel groove is smaller than the diameter of the sliding post, and the bottom width of the channel groove is larger than the diameter of the sliding post.
[0009] Preferably, the surface of the sliding clamp is made of a rough material.
[0010] Preferably, a connecting hole is provided on the top of the slide.
[0011] Preferably, a mounting plate is installed on the other side of the clamping block, and a plurality of mounting holes are formed on the mounting plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By cooperating with the channel groove and the sliding clamping column, the sliding plate can drive the sliding clamping column to move in the channel groove. When the sliding clamping column moves to the narrower part of the top of the channel groove, the door frame in the channel groove can be clamped by the sliding clamping column. Since the clamping block is installed on the car door through the mounting plate, the clamping block is always subjected to the downward force of the car door, so that the door frame is clamped tighter and tighter. On the contrary, when the car door is lifted, the sliding clamping column will move to the wider part of the bottom of the channel groove to loosen the door frame so that it can move freely. A single staff member can lift the cage door section by section. When loosening, the cage door is clamped by the sliding clamping column and will not fall, providing sufficient space for escape. The safety device can be installed at any position through the mounting plate and the mounting hole, and it is highly versatile. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.
[0020] See also Figure 1-4 As shown, the utility model provides a technical solution: a construction elevator cage door anti-falling safety device, comprising a card block 1, a channel groove 2 is opened on one side of the card block 1, and two shift blocks 3 are arranged in the channel groove 2;
[0021] The outer side of the clamping block 1 is slidably connected with a slide plate 4, and the shifting block 3 is fixedly connected to the slide plate 4;
[0022] The channel groove 2 and the two shift blocks 3 form a accommodating cavity which is wider at the bottom and narrower at the top. A sliding column 5 is arranged in the accommodating cavity. The sliding column 5 can be driven to move in the channel groove 2 by the sliding plate 4. When the sliding column 5 moves to the narrower part at the top of the channel groove 2, the door frame in the channel groove 2 can be clamped by the sliding column 5. Since the clamping block 1 is installed on the car door through the mounting plate 7, the clamping block 1 is always subjected to the downward force of the car door, so that the door frame is clamped tighter and tighter. On the contrary, when the sliding column 5 moves to the wider part at the bottom of the channel groove 2, the door frame will be loosened so that it can move freely.
[0023] Furthermore, the top width of the channel groove 2 is smaller than the diameter of the sliding column 5, and the bottom width of the channel groove 2 is larger than the diameter of the sliding column 5. The top width of the channel groove 2 is smaller than the diameter of the sliding column 5, so that the sliding column 5 can clamp the door frame in the channel groove 2, and the bottom width of the channel groove 2 is larger than the diameter of the sliding column 5, which can facilitate the sliding column 5 to be installed in the channel groove 2.
[0024] Furthermore, the surface of the sliding post 5 is made of a rough material, which can better fit with the door frame and increase friction.
[0025] Furthermore, a connection hole 6 is provided at the top of the slide 4, and the connection hole 6 can be connected to the control device to make the triggering more accurate.
[0026] Furthermore, a mounting plate 7 is installed on the other side of the clamping block 1 , and a plurality of mounting holes 8 are formed on the mounting plate 7 . The clamping block 1 can be mounted on the car door through the mounting plate 7 and the mounting holes 8 .
[0027] Working principle: First, move a construction elevator cage door anti-fall safety device to the working position. When in use, the first step is to install the card block 1 on the construction elevator cage door through the mounting plate 7 and the mounting hole 8. The second step is to insert the channel groove 2 into the door frame that matches the construction elevator cage door. The third step is to lift the slide 4 through the connecting hole 6, and the dial block 3 lifts the sliding card column 5 to a narrower place. The fourth step is that as the cage door falls, the sliding card column 5 contacts the channel groove 2 more closely, so that the cage door is stuck down and cannot fall. The fifth step is that the user lifts the car door, and then lets go to get stuck in the current position. After lifting it up section by section, you can escape. This completes the use process of a construction elevator cage door anti-fall safety device.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
