Description

Technical Field

[0001] The present application relates to the technical field of elevator installation, and in particular to a buffer pile for elevator installation. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin. It is used to carry people or goods in multi-story buildings. The buffer pile installed in the elevator is part of the elevator's safety protection device. Its main function is to absorb and reduce the impact force when an accident occurs during the operation of the elevator, thereby protecting the safety of passengers and the elevator itself.

[0003] Based on the installation and use of existing elevators, we found that the buffer pile, a key component, has some shortcomings in actual use. Specifically, these buffer piles are not very effective in absorbing the impact force that may be generated during the operation of the elevator, which means that in an emergency, the buffer pile may not fully play its expected protective role, thereby increasing the risk of passenger injury; in addition, the buffer pile equipment often lacks necessary lubrication measures in long-term operation. Lubrication is crucial for any mechanical moving parts. It can not only reduce the friction between parts and extend the service life of the equipment, but also improve the operating efficiency and stability of the equipment. Lack of lubrication of the buffer pile may cause the noise in the elevator to increase, the movement is not smooth, and may even cause failures due to excessive friction, which will undoubtedly affect the safety of passengers and the normal operation of the elevator.

[0004] Therefore, in order to solve the above problems, the present application provides an elevator installation buffer pile.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0008] Preferably, the force-bearing part comprises a mounting block and a pressure-resistant plate, wherein the mounting block is fixedly mounted on the top of the oil collecting part, and the pressure-resistant plate is fixedly mounted on the top of the mounting block.

[0010] Preferably, the buffer part also includes a bottom plate, a top plate, a liquid outlet, a second spring and a blocking piece, wherein the top plate is fixedly installed on the top of the piston rod, and the bottom plate is fixedly installed on the bottom of the piston rod, liquid outlets for the circulation of hydraulic oil are provided at both ends of the bottom plate, and the bottom plate is in contact with the inner wall of the oil collecting part, and the blocking piece is arranged at the bottom of the liquid outlet through the second spring transmission.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] The buffer pile installed in the elevator is used in coordination with the force-bearing part, the dirt collecting part and the buffer part. When the elevator reaches the target floor, the top plate is pressed downward and the first spring is compressed. At this time, the piston rod will drive the bottom plate, the second spring and the blocking piece to move downward along the inner wall of the oil collecting part. The hydraulic oil inside the oil collecting part generates resistance to the bottom plate, further achieving the buffering effect. During the downward pressure of the bottom plate, the blocking piece presses the second spring upward until the blocking piece blocks the liquid outlet.

[0022] The force-bearing part 2 includes a mounting block 201 and a pressure-resistant plate 202 , wherein the mounting block 201 is fixedly mounted on the top of the oil collecting part 1 , and the pressure-resistant plate 202 is fixedly mounted on the top of the mounting block 201 .

[0023] The dirt collecting part 3 includes a convex pipe 301 and a filter cover 302, wherein the convex pipe 301 is detachably installed between the oil collecting part 1 and the base 6, and the filter cover 302 is placed in the inner cavity of the convex pipe 301; through the setting of the filter cover 302, the hydraulic oil flowing into the filter cover 302 is filtered to prevent the waste residue in the oil from being introduced into the mounting block 201 again through the pipeline 5, thereby causing wear of the piston rod 401.

[0024] The buffer part 4 also includes a bottom plate 402, a top plate 404, a liquid outlet 405, a second spring 406 and a plugging piece 407, wherein the top plate 404 is fixedly installed on the top of the piston rod 401, and the bottom plate 402 is fixedly installed on the bottom of the piston rod 401, and liquid outlet holes 405 for hydraulic oil circulation are provided at both ends of the bottom plate 402, and the bottom plate 402 is in contact with the inner wall of the oil collecting part 1, and the plugging piece 407 is arranged at the bottom of the liquid outlet 405 through the transmission of the second spring 406.

[0025] The piston rod 401 movably passes through the anti-pressure plate 202 and the mounting block 201 , and a gap is left between the mounting block 201 and the piston rod 401 .

[0028] When the elevator reaches the target floor, the top plate 404 is pressed downward and the first spring 403 is compressed. At this time, the piston rod 401 will drive the bottom plate 402, the second spring 406 and the blocking piece 407 to move downward along the inner wall of the oil collecting part 1. The hydraulic oil inside the oil collecting part 1 generates resistance to the bottom plate 402, further achieving a buffering effect. In the process of the bottom plate 402 being pressed downward, the blocking piece 407 presses the second spring 406 upward until the blocking piece 407 blocks the liquid outlet 405.

[0029] Furthermore, the hydraulic oil in the oil collecting section 1 is discharged along the pipeline 5 to the outer wall of the piston rod 401, lubricating the piston rod 401, reducing the friction between the components and extending the service life of the equipment; when the piston rod 401 returns to its initial state, the second spring 406 drives the blocking piece 407 to rebound, and the hydraulic oil in the oil collecting section 1 will flow along the liquid outlet 405 to the bottom of the oil collecting section 1.
