Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an automatic flip transition pedal of a construction hoist. Background Art

[0002] Construction elevators, also known as construction lifts, outdoor elevators, and passenger and cargo elevators, are commonly used in construction to transport people and cargo. They are primarily used for interior and exterior decoration of high-rise buildings, as well as for the construction of bridges, chimneys, and other structures. During elevator operation, to address the gap between the cage and the landing, transition steps are typically installed. These automatically flip and deploy when the elevator reaches a designated landing, filling the gap and preventing people or cargo from accidentally falling during entry and exit, thereby improving operational safety.

[0003] However, after the cage door of existing construction elevators is opened, workers usually need to manually push the transition pedal. However, sometimes due to the tools in the workers' hands, they cannot push the transition pedal quickly to block the gap between the cage and the floor station, which affects work efficiency and poses certain safety risks.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a kind of automatic flipping transition pedal for a construction elevator as Figure 1-6 shown, which includes a groove 2 opened on the outer wall of one side of the elevator cage door 1. A biaxial motor 5 is fixedly installed in the groove 2. A control switch is fixedly installed on the inner wall of the elevator cage door 1, and the control switch is electrically connected to the biaxial motor 5 through a wire. Rotating rods 6 are respectively fixedly installed on the two output shafts of the biaxial motor 5, and both of the two rotating rods 6 are rotatably connected to the inner wall of the groove 2. First pulleys 7 are respectively fixedly sleeved on the two rotating rods 6. A transition pedal 4 is arranged inside the elevator cage door 1. In order to protect workers and prevent them from falling from both sides of the transition pedal 4 and improve the safety of the device, guardrails 18 are respectively fixedly installed on the outer walls of both sides of the transition pedal 4. Cross bars 3 are respectively fixedly installed on both sides of the transition pedal 4, and both of the two cross bars 3 are rotatably connected to the inner walls of both sides of the elevator cage door 1. Second pulleys 20 are respectively fixedly sleeved on the two cross bars 3, and synchronous belts 8 are respectively sleeved on the two first pulleys 7 and the second pulleys 20. By driving the rotation of the rotating rod 6 by the rotation of the biaxial motor 5, driving the rotation of the first pulley 7 by the rotation of the rotating rod 6, driving the rotation of the second pulley 20 by the rotation of the first pulley 7 through the synchronous belt 8, driving the rotation of the cross bar 3 by the rotation of the second pulley 20, and driving the counterclockwise rotation of the transition pedal 4 by the rotation of the cross bar 3 to be lapped on the landing station, thereby automatically filling the gap between the cage and the landing station, so that workers no longer need to manually push the transition pedal 4, improving work efficiency and safety.

[0022] In order to keep the synchronous belt 8 in a proper tension state all the time, thereby avoiding problems such as slipping, jumping or breaking caused by the synchronous belt 8 being too loose or too tight, reducing the probability of faults, and at the same time reducing the wear and fatigue of the synchronous belt 8 and prolonging its service life, a cross plate 9 is fixedly installed in the groove 2. Two mounting plates 15 are respectively arranged at the top and bottom of the cross plate 9. Two fixing rods 10 are respectively slidably installed on the four mounting plates 15. In order to reduce the friction between the fixing rod 10 and the mounting plate 15, thereby reducing the wear degree of the fixing rod 10 and improving the service life of the fixing rod 10, two through holes are respectively opened on the four mounting plates 15. Linear bearings are respectively fixedly installed in the eight through holes. The eight fixing rods 10 respectively penetrate through the corresponding linear bearings and are respectively slidably connected with the inner walls of the corresponding linear bearings. In order to limit the mounting plate 15 and make the mounting plate 15 always slidably installed on the fixing rod 10, limiting plates 16 are respectively fixedly installed at one ends of the eight fixing rods 10. Mounting boxes 13 are respectively fixedly installed on the outer walls of one sides of the four mounting plates 15. Rotating columns 14 are respectively rotatably installed in the four mounting boxes 13. Push tubes 17 are respectively fixedly sleeved on the four rotating columns 14, and the four 17 push tubes are respectively in contact with the corresponding synchronous belt 8. Compression springs 12 are respectively fixedly installed on the outer walls of one sides of the four mounting plates 15, and one ends of the four compression springs 12 are respectively fixedly connected with the corresponding cross plate 9. In order to improve the service life of the compression spring 12, the surfaces of the four compression springs 12 are all tinned.

[0023] The working principle of the automatic flipping transition pedal of the construction elevator provided by the utility model is as follows: In the initial state, the compression spring 12 is in a compressed state. The two push tubes 17 always push the synchronous belt 8 through the compression spring 12, thereby keeping the synchronous belt 8 in a proper tension state all the time, thereby avoiding problems such as slipping, jumping or breaking caused by the synchronous belt 8 being too loose or too tight, reducing the probability of faults, and at the same time reducing the wear and fatigue of the synchronous belt 8 and prolonging its service life. When the elevator cage door 1 reaches the same height position as the landing, the worker starts the control switch in the elevator cage door 1 to make the double-shaft motor 5 rotate. The rotation of the double-shaft motor 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the first pulley 7 to rotate. The rotation of the first pulley 7 drives the second pulley 20 to rotate through the synchronous belt 8. The rotation of the second pulley 20 drives the cross bar 3 to rotate. The rotation of the cross bar 3 drives the transition pedal 4 to rotate counterclockwise and lap on the landing, thereby automatically filling the gap between the cage and the landing, so that the worker no longer needs to manually push the transition pedal 4, improving work efficiency and safety.

[0024] Compared with the related technology, the automatic flipping transition pedal of the construction elevator provided by the utility model has the following beneficial effects:

[0025] The utility model provides an automatically flipping transition pedal for a construction hoist. By means of a compression spring 12, two push tubes 17 always push a synchronous belt 8, so that the synchronous belt 8 is always kept in a proper tension state, reducing problems such as slipping, jumping or breaking, decreasing the probability of faults occurring, and at the same time reducing the abrasion and fatigue of the synchronous belt 8 and prolonging its service life. When the hoist cage door 1 reaches the position at the same height as the landing, a worker starts a control switch inside the hoist cage door 1 to rotate a biaxial motor 5, which drives a cross bar 3 to rotate, so that the transition pedal 4 rotates counterclockwise and is lapped on the landing, thereby automatically filling the gap between the cage and the landing, and enabling the worker not to need to manually push the transition pedal 4, improving work efficiency and safety.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement on some of the technical features.
