Description

Technical Field

[0001] The utility model belongs to the technical field of construction hoists, and particularly relates to a moving guiding structure for the car door of a construction hoist. Background Art

[0002] A construction hoist, also known as a construction elevator for buildings, can also be called an outdoor elevator or a construction site elevator. It is a construction machinery for carrying people and goods frequently used in construction, mainly used for the interior and exterior decoration of high-rise buildings, the construction of buildings such as bridges and chimneys.

[0003] The car is one of the main components of a construction hoist, mainly a box-shaped space for carrying and transporting people and materials. The car generally consists of main components such as a car bottom, car walls, car top, and car door, and its internal net height should be at least 2m.

[0004] After on-site investigation, the applicant found that the sill of the car of the current construction hoist is similar to the structure disclosed in the application number 202321774322.2. In order to ensure the accurate moving docking position of the car door, it is provided with a groove that slidably matches the car door. However, such grooves are prone to slag accumulation in the construction site environment. Then, this will cause the car door to be blocked by the accumulated slag when closing, resulting in the car door being unable to close completely. In severe cases, it will also cause damage to the door machine and deformation of the car door. It is necessary to manually clean the accumulated slag, and the cleaning of the stuck accumulated slag is relatively difficult and thus laborious. Therefore, it is necessary to optimize and improve the structure. Content of the Utility Model

[0005] Aiming at the problems raised in the above background art, the purpose of the utility model is to provide a moving guiding structure for the car door of a construction hoist.

[0006] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:

[0007] A moving guiding structure for the car door of a construction hoist, including a door machine and a sill. The output end of the door machine is adaptively installed with a left inner door, a left outer door, a right inner door, and a right outer door. Triangular blocks are installed at the bottoms of the left inner door and the left outer door, and an avoidance opening with a corresponding specification and size to the triangular blocks is provided at the bottom of the right outer door.

[0008] The upper surface of the sill is a horizontal plane. The sill is provided with through slot openings corresponding to the left inner door, the left outer door, the right inner door, and the right outer door. Guide rods located in the through slot openings are connected to the lower end faces of the left inner door, the left outer door, the right inner door, and the right outer door.

[0009] Further limited, a plurality of rib plates are equidistantly installed on the sill. The rib plates are provided with avoidance slot openings corresponding to the guide rods in terms of specification, position, and size. Such a design strengthens the structural strength of the sill without blocking the movement of the guide rods.

[0010] Further limitation: The sill is connected to the car beam and the toe guard at a right angle, and an inclined support bar is connected between the car beam and the toe guard. With such a design, the car beam, the toe guard, and the inclined support bar form a triangle, and the sill is located at the corner point of the triangle, further strengthening the load-bearing strength of the sill.

[0011] Further limitation: Neither side of the front and rear of the avoidance opening is blocked. With such a design, when the triangular block pushes the accumulated slag to move and contacts the bottom of the avoidance opening, the accumulated slag is forced to be discharged to both sides, thereby achieving the purpose of automatically dredging the moving space.

[0012] Further limitation: The sharp corner of the triangular block is on the center line of the through slot opening. With such a design, it ensures the effect of pushing the accumulated slag to both sides.

[0013] Beneficial effects of adopting the present utility model:

[0014] With the structural design of the present utility model, the design of the sill plane makes the accumulated slag not sink. Then, under the effect of the triangular block, the accumulated slag can be effectively pushed away from the position of the through slot opening to both sides, thereby ensuring that the moving area of the car door will not be blocked by the accumulated slag and ensuring the normal operation of the opening and closing of the car door;

[0015] With the structural design of the present utility model, it is possible to ensure the normal closing of the car door without manual cleaning of the accumulated slag;

[0016] With the structural design of the present utility model, the structure of the sill is easier to produce compared to the sill structure of the prior art, and because there are fewer corners, the structural strength is higher and it is less likely to deform. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0025] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0026] As Figures 1 to 5 shown, a moving guide structure for the car door of a construction hoist according to the present utility model includes a door machine 1 and a sill 2. The output end of the door machine 1 is adaptively installed with a left inner door 3, a left outer door 4, a right inner door 5 and a right outer door 6. Triangular blocks 7 are installed at the bottoms of the left inner door 3 and the left outer door 4, and an avoidance opening 8 corresponding to the triangular block 7 in terms of specification and size is provided at the bottom of the right outer door 6;

[0027] The upper surface of the sill 2 is a horizontal plane. The sill 2 is provided with through slot openings 9 corresponding to the positions of the left inner door 3, the left outer door 4, the right inner door 5 and the right outer door 6. The lower end surfaces of the left inner door 3, the left outer door 4, the right inner door 5 and the right outer door 6 are all connected with guide rods 10 located in the through slot openings 9.

[0028] In this embodiment, when using a moving guide structure for the car door of a construction hoist, the door machine 1 operates to drive the left inner door 3, the left outer door 4, the right inner door 5 and the right outer door 6 to move above the sill 2, so as to achieve the purpose of opening and closing. This movement mode can be understood and realized by those in the relevant field;

[0029] During the movement of the left inner door 3, the left outer door 4, the right inner door 5 and the right outer door 6, they are limited by the guide rods 10 and the through slot openings 9, so as to ensure the accurate alignment between the left inner door 3, the left outer door 4, the right inner door 5 and the right outer door 6 and ensure the normal opening and closing;

[0030] During the movement of the left inner door 3 and the left outer door 4, the triangular blocks 7 are driven to move. During the movement of the triangular blocks 7, benefiting from the sharp corners and the inclined surfaces on both sides of the triangular blocks 7, when there is accumulated slag on the horizontal plane of the sill 2, the fine accumulated slag directly falls out through the through slot openings 9. When the accumulated slag stuck in the through slot openings 9 or failed to pass through the through slot openings 9 comes into contact with the sharp corners of the triangular blocks 7, it will be pushed, and during the pushing process, it will be separated and pushed to both sides by the triangular blocks, so as to ensure that there is no accumulated slag on the through slot openings 9, that is, on the moving track of the car door, and further ensure the normal closing of the car door. Moreover, this method does not require manual cleaning, so it is labor-saving.

[0031] Preferably, a plurality of rib plates 11 are equidistantly installed on the sill 2. The rib plates 11 are provided with avoidance notches 12 corresponding to the guide rods 10 in terms of specification position dimensions. With such a design, while strengthening the structural strength of the sill 2, it will not block the movement of the guide rods 10. In fact, the number and structural shape of the rib plates 11 can also be considered according to specific situations.

[0032] Preferably, the sill 2 is connected to the car beam 13 and the toe guard 14 at a right angle. An inclined support bar 15 is connected between the car beam 13 and the toe guard 14. With such a design, the car beam 13, the toe guard 14, and the inclined support bar 15 form a triangle, and the sill 2 is located at the corner position of the triangle, further strengthening the bearing strength of the sill 2. In fact, an auxiliary support structure for strengthening the bearing strength of the sill 2 can also be considered according to specific situations.

[0033] Preferably, neither the front nor the back sides of the avoidance opening 8 are blocked. With such a design, when the triangular block 7 pushes the accumulated slag to move and contacts the bottom of the avoidance opening 8, the accumulated slag is forced to be discharged to both sides, so as to achieve the purpose of automatically dredging the moving space. In fact, the structural style of the avoidance opening 8 can also be considered according to specific situations.

[0034] Preferably, the sharp corner of the triangular block 7 is on the center line of the through notch 9. With such a design, the effect of pushing the accumulated slag to both sides is ensured. In fact, the structural shape of the triangular block 7 can also be considered according to specific situations.

[0035] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than being used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
