Description

Technical Field

[0001] The present application relates to the technical field of elevator carriages, and in particular to an elevator carriage frame that is convenient to adjust. Background Art

[0002] The elevator carriage frame is the load-bearing structure of the elevator carriage. The load (self-weight and load) of the elevator carriage is transmitted by it to the traction steel wire rope. When the safety gear acts or the bottom collision buffer is hit, it also has to bear the resulting reaction force. Therefore, the elevator carriage frame must have sufficient strength.

[0003] As disclosed in a Chinese patent CN218579386U for an elevator carriage frame, the main problem it solves is that through the arrangement of the first vertical rod and the second vertical rod, it is possible to conveniently adjust the overall height of the elevator carriage frame, so as to adapt to elevator carriages of different heights. Through the arrangement of the beam, the diagonal tension assembly and the bottom plate assembly, it is possible to conveniently carry the elevator carriage.

[0004] This carriage frame can adjust the height of the carriage frame through the first vertical rod and the second vertical rod, but this carriage frame cannot adjust the lateral distance between the first vertical rod and the second vertical rod. In this way, this carriage frame can only be adaptively installed for carriage frames of the same width. Therefore, the limitations of this carriage frame are relatively large, and it is not convenient for the staff to install and use. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will Figures 1-4 further describe this application in detail with reference to the Embodiment

[0032] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: an elevator car frame that is easy to adjust, including a first vertical rod 1, a second vertical rod 2 hinged to the outer wall of the first vertical rod 1, an adjusting mechanism 31 provided at the bottom end of the first vertical rod 1, and a buffer mechanism 32 provided below the adjusting mechanism 31. The adjusting mechanism 31 includes a support plate 311 provided at the bottom end of the first vertical rod 1. A chute 312 is opened at the top end of the support plate 311. A slider 313 is slidably connected to the inner wall of the chute 312. The top end of the slider 313 is fixedly connected to an adjusting bottom plate 314. The adjusting bottom plate 314 is connected to the first vertical rod 1 and the second vertical rod 2. The outer wall of the adjusting bottom plate 314 is in tight fit with the outer wall of a support sliding plate 315. A sliding hole is opened on the outer wall of the adjusting bottom plate 314, and a support sliding plate 315 is slidably connected to the inner wall of the sliding hole. A reinforcing plate 318 is fixedly connected to the outer wall of the middle part of the support sliding plate 315. A groove is opened at the top end of the support sliding plate 315, and a hydraulic rod 316 is fixedly connected to the inner wall of the groove. The outer wall of the top end of the hydraulic rod 316 is fixedly connected to a fixing block 317. The top end of the fixing block 317 is fixedly connected to the top end of the inner wall of the adjusting bottom plate 314. A cross plate 319 is fixedly connected to the top end of the first vertical rod 1. A concave hole is opened at one end of the cross plate 319, and a sliding rod 3110 is slidably connected to the inner wall of the concave hole. The end of the sliding rod 3110 away from the concave hole is fixedly connected to the outer wall of another cross plate 319.

[0033] Further, a connecting plate is fixedly connected to the top end of the support plate 311, and the top end of the connecting plate is fixedly connected to the bottom end of the reinforcing plate 318, so as to support the reinforcing plate 318, thereby playing a role in supporting and limiting the support sliding plate 315.

[0034] Furthermore, the number of the hydraulic rods 316 is four. The two hydraulic rods 316 are in a group and are symmetrically distributed on the left and right in the support sliding plate 315. In this way, the adjusting bottom plates 314 on the left and right can be driven to move left and right on the outer wall of the support sliding plate 315, so as to realize the adjustment of the horizontal distance.

[0035] The buffer mechanism 32 includes a damper 321 fixedly connected to the bottom end of the support plate 311. One end of the damper 321 away from the support plate 311 is fixedly connected to a bottom plate 322. A buffer bump 323 is fixedly connected to the bottom end of the support plate 311, and a spring 324 is fixedly connected to the bottom end of the support plate 311.

[0036] Further, the number of the dampers 321 is four. The two dampers 321 are in a group and are symmetrically distributed on the left and right at the top end of the bottom plate 322. In this way, the four corners of the support plate 311 can be buffered, so as to buffer the overall car and improve the stability.

[0037] Furthermore, the number of the buffer bumps 323 is four. Two buffer bumps 323 form a group and are symmetrically distributed on the bottom end of the support plate 311 in a left-right symmetry structure, so as to buffer and protect the bottom end of the support plate 311, prevent the support plate 311 from directly contacting the bottom plate 322, and cause wear.

[0038] The implementation principle of this application is as follows: When it is necessary to adjust according to the lateral dimension of the car, the hydraulic rod 316 can be started to expand and contract. When the output end of the hydraulic rod 316 moves, the fixed block 317 can be driven to move. When the fixed block 317 moves, the adjustment bottom plate 314 can be driven to move. At this time, the adjustment bottom plate 314 can move on the outer wall of the support slide plate 315, and at the same time drive the slider 313 to move on the inner wall of the chute 312. The stability of the adjustment bottom plate 314 during the movement can be improved through the movement of the slider 313, so that the adjustment bottom plates 314 on both sides can be adjusted, thereby completing the adjustment work. The middle part of the support slide plate 315 can be strengthened through the reinforcement plate 318, so as to improve its strength and strengthen the support effect.

[0039] When the car drops, first the bottom plate 322 contacts the ground, and then the pressure when the car drops is buffered and weakened through the cooperation between the damper 321 and the spring 324. In this way, the vibration force generated when the car lands can be reduced, the comfort during riding can be improved, and at the same time, the overall car can be buffered and protected, and the service life of the car can be improved. The buffer bumps 323 can prevent the bottom end of the support plate 311 from directly contacting the top end of the bottom plate 322 to reduce its wear, thereby improving the service life of the car and further improving the buffering effect of the car.

[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
