Technical Field

[0001] The utility model relates to the technical field of building material transportation, in particular to an anti-falling device for a building construction elevator. Background Technique

[0002] When transporting building materials from a low place to a high place, an elevator is needed. The existing elevator consists of a scissor lift and a base plate connected thereto. Through the drive of a hydraulic cylinder, the scissor lift rotates and displaces, pushing the base plate upward to the height of the delivery point and then unloading the goods. The following problems exist in the prior art:

[0003] First, when on the ground, in order to carry building materials onto the base plate, no protection mechanism is installed around the base plate. Therefore, there is a risk of building materials falling during the process of transporting building materials to a high place;

[0004] Second, when unloading, usually workers enter the base plate and unload the goods from the base plate by pulling or pushing manually, which increases labor and risk;

[0005] In view of the above problems, we propose an anti-falling device for a building construction elevator. Content of the Utility Model

[0033] According to Figures 1 - 8 Shown is a fall prevention device for a construction hoist. The main structure of the device is a scissor lift 1. A base plate 2 is provided on the scissor lift 1. Anti-fall plates 3 are rotatably provided on the four side edges of the base plate 2. The four anti-fall plates 3 are driven to each other through bevel gears 4. The bevel gears 4 are symmetrically distributed and fixedly connected to both ends of the rotating shafts of the anti-fall plates 3. The bevel gears 4 on adjacent two anti-fall plates 3 are meshed with each other. The anti-fall plates 3 are driven to rotate through a pulley drive mechanism 8. The pulley drive mechanism 8 includes a drive motor 20, a motor shaft 21, pulleys 22, and a connecting belt 23. The drive motor 20 is fixedly connected to the lower end of the base plate 2 through a support frame. The motor shaft 21 is fixedly connected to the output end of the drive motor 20. There are two pulleys 22, which are coaxially and fixedly connected to the motor shaft 21 and the anti-fall plate 3 respectively. The two pulleys 22 are connected through the connecting belt 23. When the drive motor 20 is started, it drives the motor shaft 21 to rotate, drives the pulley 22 thereon to rotate, and through the connecting belt 23, drives the other pulley 22 to rotate, drives the anti-fall plate 3 to rotate, so that the corresponding anti-fall plate 3 can be rotated to a vertical state or a horizontal state. When the anti-fall plate 3 is horizontal, it is convenient to place building materials. When it is vertical, it can prevent the building materials from falling. When one anti-fall plate 3 rotates, it drives another bevel gear 4 meshed with the bevel gear 4 to rotate through the bevel gear 4, drives another anti-fall plate 3 to rotate, and so on. The four anti-fall plates 3 can rotate simultaneously.

[0034] A coil spring plate mechanism 5 is connected between the base plate 2 and the anti-falling plate 3. The coil spring plate mechanism 5 includes a first rotating rod 11, a second rotating rod 12, a disc spring 13, and a pull rope 14. The first rotating rod 11 is fixedly connected to the anti-falling plate 3, and the second rotating rod 12 is fixedly connected to the base plate 2. The disc spring 13 is sleeved on the second rotating rod 12, and the inner end of the disc spring 13 is fixedly connected to the second rotating rod 12. One end of the pull rope 14 is fixedly connected to the outer end of the disc spring 13, the pull rope 14 is wound around the disc spring 13, and the other end of the pull rope 14 is fixedly connected to the first rotating rod 11. During the process of the anti-falling plate 3 rotating to be parallel to the base plate 2, the pull rope 14 unfolds from the state of being wound around the disc spring 13 (the same principle as the tape measure releasing the tape), the disc spring 13 tightens, and its elastic potential energy increases, providing elastic potential energy for the pull rope 14 to be wound around the disc spring 13.

[0035] A stabilizing mechanism 6 connected to the base plate 2 is connected to the coil spring plate mechanism 5. The stabilizing mechanism 6 includes a rotating shaft rod 15 and a stabilizing rope 16. The rotating shaft rod 15 is fixedly connected to the base plate 2. One end of the stabilizing rope 16 is fixedly connected to the rotating shaft rod 15, and the other end is connected to the pull rope 14 and kept smooth through an elastic telescopic member 17. When the anti-falling plate 3 is perpendicular to the base plate 2, the stabilizing rope 16 is attached to the pull rope 14. When the anti-falling plate 3 is parallel to the base plate 2, the stabilizing rope 16 is in a taut state. By pulling the pull rope 14, the anti-falling plate 3 is pulled, reducing the force on the disc spring 13. During the process of the anti-falling plate 3 changing from parallel to perpendicular to the base plate 2, the disc spring 13 expands, driving the pull rope 14 to be wound around the disc spring 13 (the same principle as the tape measure retracting the tape), and when the disc spring 13 continues to expand, the stabilizing rope 16 is wound around the surface of the pull rope 14.

[0036] A displacement type transport seat plate 7 is provided on the base plate 2. The displacement type transport seat plate 7 includes a support plate 18 and a transmission mechanism 19. The support plate 18 is slidably arranged on the base plate 2 and is displaced through the transmission mechanism 19. The transmission mechanism 19 includes a motor 24, a threaded rod 25, and a threaded sleeve 26. The motor 24 is fixedly connected to the base plate 2, the threaded rod 25 is fixedly connected to the output end of the motor 24, the threaded sleeve 26 is fixedly connected to the support plate 18, and the connection mode between the threaded rod 25 and the threaded sleeve 26 is a threaded connection. When building materials are transported to a high place, the driving motor 20 is started to make the anti-falling plate 3 flush with the building platform. The motor 24 is started to drive the threaded rod 25 to rotate, thereby driving the support plate 18 to slide and move closer to the construction platform. A moving wheel 27 is connected to the lower end of the support plate 18 to facilitate the movement of the support plate 18 on the workbench.

[0037] The elastic telescopic member 17 includes elastic telescopic rods 9 and a cross bar 10. There are two groups of elastic telescopic rods 9, and their fixed ends are fixedly connected to the upper end surface of the base plate 2. The cross bar 10 is rotatably arranged at the extended ends of the two elastic telescopic rods 9 and is pressed against the stabilizing rope 16 to ensure the smoothness of the stabilizing rope 16.
