Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a high-safety elevator car frame. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. A vertical lift has a car that runs between at least two rows of rigid guide rails that are perpendicular or have an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

[0003] The prior art, such as publication number CN201240739Y, provides a gas spring suspension device for a high-speed elevator car, which is composed of a car frame, a support beam and a traction wire rope, the upper end of the car frame is connected to the support beam, the traction wire rope is connected to the support beam, the car frame is composed of a car outer frame and a car inner frame, a first gas spring is arranged between the upper end of the car outer frame and the support beam, a first bracket is arranged on the outer side of the upper end of the car inner frame side plate, a second bracket is arranged on the inner side of the upper end of the car outer frame side plate, a second gas spring is arranged between the first bracket and the second bracket, and an anti-side stabilization device is arranged on the inner side of the lower end of the car outer frame side plate, and the anti-side stabilization device is an anti-side stabilization rubber pad. The utility model adopts two sets of gas spring suspension devices in the gas spring suspension device for a high-speed elevator car. Since the stiffness of the gas spring is variable, the high-frequency and low-frequency vibrations of the elevator car can be effectively absorbed, and the vibration caused by the change of the elevator load can be effectively reduced, so that the car frame works smoothly, improves its comfort and safety, and reduces energy consumption.

[0004] This scheme uses two sets of suspension devices, which can effectively buffer the vibration caused by the up and down movement of the car. However, the car and the frame are mainly connected by gas springs as the intermediate contact. Although it can play a good role when the car moves up and down, the gas spring itself uses its own air tightness to compress the internal air for buffering, and the weight distribution inside the car is uneven when people are loaded and unloaded, which may cause the gas spring as a connecting medium to be subjected to excessive force on one side. If this continues for a long time, it is easy to affect its air tightness, resulting in a decrease in its shock absorption effect. In view of this, we propose a high-safety car with an elevator frame. Utility Model Content

[0005] The utility model aims to provide a high-safety elevator frame car, which solves the problem that a gas spring as a connecting medium is easily subjected to excessive force on one side, affecting its air tightness and causing its shock absorption effect to decrease.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The buffer mechanism includes a load-bearing beam, which is fixedly connected to the top of the supporting frame. A circle of connecting seats is connected to the bottom of the load-bearing beam. A disc-shaped groove is opened on the inner wall of the connecting seat. A disc is arranged on the inner wall of the disc-shaped groove. A connecting rod is fixedly connected to the bottom of the disc. A connecting seat and a connecting rod are arranged under the load-bearing beam as an intermediate medium connecting the car and the supporting frame. Through the connection relationship between the disc-shaped groove and the disc, when the car shakes in the supporting frame, a certain displacement space between the disc-shaped groove and the disc can be used as a buffer to avoid the situation where the connecting component is deformed due to force on one side, affecting its functionality.

[0009] Preferably, the bottom shape of the inner wall of the disc-shaped groove is set to be a cone, and the bottom shape of the disc is set to be a cone and fits with the bottom of the inner wall of the disc-shaped groove. By setting the bottom of the disc and the bottom of the inner wall of the disc-shaped groove to be conical and fit together, the disc is automatically reset by the traction of the weight of the car below, so as to ensure that the car is in a stable state when in normal use.

[0010] Preferably, the buffer mechanism further comprises a connecting ring, the connecting ring is connected to the bottom of the connecting rod, a connecting column is arranged inside the connecting ring, and the connecting column is fixedly connected to the top of the car.

[0011] Preferably, a circle of first gas spring is fixedly connected to the top of the connecting ring, and a support plate is fixedly connected to the top of the first gas spring. The support plate is fixedly connected to the top of the connecting column. The first gas spring is set on the top of the connecting ring, and the car is connected through the connecting column under the support plate. By setting the gas inside the first gas spring itself as a buffer medium, the high-frequency and low-frequency vibrations of the car can be effectively absorbed, and the vibration caused by the change of the car load can be effectively reduced, so that the support frame can work smoothly.

[0012] Preferably, the limit assembly includes a limit plate, a slide groove, and a slide plate, the limit plate is fixedly connected to one side of the inner wall of the support frame, the slide groove is opened on the inner wall of the limit plate, the slide plate is slidably connected to the inner wall of the slide groove, and the slide plate is fixedly connected to one side of the outer wall of the car. By setting the slide plate to slide on the inner wall of the slide groove, the car is limited in a manner that allows the car to move up and down in the support frame while limiting the shaking of the car in other directions to ensure the stability of the normal up and down movement of the car.

[0013] Preferably, the inner wall of the slide groove is in a convex shape, and the outer wall of the slide plate is in a convex shape and is adapted to the shape of the inner wall of the slide groove.

[0014] Preferably, a second gas spring is fixedly connected to the bottom of the inner wall of the slide groove, and a rubber pad is fixedly connected to the top of the second gas spring, so as to provide secondary protection for the car when the buffer mechanism above the car fails and breaks and cannot provide sufficient traction to support the weight of the car.

[0015] By means of the above technical solution, the utility model provides an elevator frame with high safety. It has at least the following beneficial effects:

[0016] 1. The utility model provides a connecting seat and a connecting rod as an intermediate medium for connecting the car and the supporting frame under the load-bearing beam, and the connection relationship between the disc-shaped groove and the disc allows a certain displacement space between the disc-shaped groove and the disc to serve as a buffer when the car shakes in the supporting frame, so as to avoid the situation where the connecting component is deformed due to force on one side and affects its functionality. The bottom of the disc and the bottom of the inner wall of the disc-shaped groove are arranged in a conical surface and fit together, so that when the disc is displaced in the disc-shaped groove, the disc can be automatically reset by the traction of the weight of the car below through the conical surface and fit together, so as to ensure that the car is in a stable state when it is used normally.

[0017] 2. The utility model uses a limit assembly to provide secondary protection for the car, buffering and supporting it when the buffer mechanism above the car fails and breaks and cannot provide sufficient traction to support the weight of the car. Since there is a certain gap between the slide plate and the second gas spring, when the car falls, the friction force generated by the slide plate sliding in the slide groove will be buffered first, and then the sliding slide compresses the second gas spring, and a second buffering is performed through the tension of the second gas spring to reduce the impact when the car falls, so as to play a protective role. The rubber pad on the top of the second gas spring can also buffer the contact between the second gas spring and the slide plate to avoid excessive impact force caused by direct contact. By setting two sets of structures of the limit assembly and the buffer mechanism, the car is provided with a multi-layer protection effect to improve the stability and safety of the overall operation of the car.
