Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator installation technology, specifically to a buffer pile for elevator installation. Background Technology
[0002] A buffer pile is a pile structure used in elevator installation to provide a buffering effect. A buffer pile, also known as an elevator buffer, is a safety device that reduces the impact and brings the elevator car or counterweight to a safe stop when the elevator car or counterweight exceeds the lowest floor and descends to the bottom of the shaft due to some abnormal reason.
[0003] Existing elevator buffer piles have a relatively simple buffer structure, which provides buffering through a single-level buffer structure. However, as the usage time and frequency increase, the buffering effect will decrease, increasing the risk to the elevator.
[0004] Therefore, it is particularly important to design a buffer pile for elevator installation to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content
[0005] The purpose of this utility model is to provide a buffer pile for elevator installation to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A buffer pile for elevator installation includes a central buffer block. Fixed seats are provided at the four corners of the top and bottom of the central buffer block. A shock-absorbing spring is installed inside each fixed seat. A pressing plate, which slidably engages with the shock-absorbing spring, is slidably installed inside the fixed seat. A stamping rod is connected to the side of the pressing plate away from the shock-absorbing spring. One end of the stamping rod, passing through the outside of the fixed seat, is connected to an upper support plate. Hollow brackets are connected to both the left and right sides of the central buffer block. Slide rails are provided on the upper and lower sides inside the hollow brackets. Slide seats are slidably connected to the outer sides of the slide rails. A sliding block is fixed between two sets of slide seats. A buffer rubber column is connected between the outer end of the sliding block and the inside of the hollow bracket. Buffer connecting rods are symmetrically rotatably connected to the middle positions of the front and rear sides of the sliding block. Shock absorbers are installed at the four corners on opposite sides of the two sets of upper support plates. External mounting plates are installed on the outer ends of the shock absorbers.
[0008] As a preferred embodiment of this utility model, the shock-absorbing spring is a steel wire compression spring, and one end of the shock-absorbing spring is fixed inside the fixed base by a thread.
[0009] As a preferred embodiment of this utility model, the external structure size of the pressing piece is adapted to the internal structure size of the fixing base.
[0010] As a preferred embodiment of this utility model, the two sets of buffer rods on the same side are rotatably connected to the corner of the inner side of the upper support plate through hinge seats.
[0011] As a preferred embodiment of this utility model, the buffer rubber column is made of elastic buffer rubber.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, a buffer pile for elevator installation is used to fix multiple sets of external mounting plates located at the bottom of the shaft pit, arranged in a matrix corresponding to the position below the elevator. When the elevator falls and contacts the external mounting plate at the top, the downward pressure first squeezes the shock absorber, releasing part of the external force. While squeezing the shock absorber, the upper support plate applies the remaining pressure to the stamping rod, causing the stamping rod to drive the pressing plate to compress the shock-absorbing spring. The steel wire compression spring is a helical spring that withstands axial pressure, with good pressure resistance and buffering properties, which can further alleviate the force of the elevator falling. Finally, under the action of force, the two sets of buffer connecting rods will contract synchronously, pushing the sliding block to move inside the hollow support with the cooperation of the slide rail and slide seat, pressurizing the buffer rubber column. The three-set structure forms a multi-level buffer structure, thus effectively releasing the buffering force of the elevator falling. Compared with a single structure, its buffering effect is significantly improved. Attached Figure Description

[0022] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0023] A buffer pile for elevator installation includes a central buffer block 1. Fixed seats 2 are provided at the four corners of the top and bottom of the central buffer block 1. A shock-absorbing spring 201 is installed inside the fixed seat 2. A pressing plate 202 that abuts against the shock-absorbing spring 201 is slidably arranged inside the fixed seat 2. A punching rod 203 is connected to the side of the pressing plate 202 away from the shock-absorbing spring 201. An upper support plate 3 is connected to one end of the punching rod 203 that passes through the outside of the fixed seat 2. Hollow brackets 4 are connected to both the left and right sides of the central buffer block 1.
[0024] The shock-absorbing spring 201 is a steel wire compression spring. One end of the shock-absorbing spring 201 is fixed inside the fixed base 2 by a thread, and the external structure size of the pressure plate 202 is adapted to the internal structure size of the fixed base 2.
[0025] In this embodiment, please refer to Figure 3 The hollow support 4 is equipped with slide rails 401 on both the upper and lower sides. Slide seats 402 are slidably connected to the outer side of slide rails 401. Sliding blocks 403 are fixed between two sets of slide seats 402. Buffer rubber columns 404 are connected between the outer end of the sliding block 403 and the interior of the hollow support 4. Buffer connecting rods 405 are symmetrically rotated and connected at the middle positions of the front and rear sides of the sliding block 403. Shock absorbers 5 are installed at the four corners on the opposite side of the two sets of upper support plates 3. External mounting plates 6 are installed at the outer ends of the shock absorbers 5.
[0026] Two sets of buffer rods 405 on the same side are rotatably connected to the corner of the inner side of the upper support plate 3 through hinge seats. The buffer rubber column 404 is made of elastic buffer rubber. The steel wire compression spring is a helical spring that bears axial pressure and has good pressure resistance and buffering performance.
[0027] The working process of this utility model is as follows: Multiple sets of external mounting plates 6 located at the bottom are fixedly installed in the pit of the shaft and distributed in a matrix at positions corresponding to the bottom of the elevator. When the elevator falls and contacts the external mounting plates 6 at the top, the downward pressure will first squeeze the shock absorber 5. The shock absorber 5 releases part of the external force. At the same time as squeezing the shock absorber 5, the upper support plate 3 will transfer the remaining pressure to the stamping rod 203, causing the stamping rod 203 to drive the pressing plate 202 to compress the shock-absorbing spring 201. The steel wire compression spring is a helical spring that withstands axial pressure. It has good pressure resistance and buffering properties, which can further alleviate the force of the elevator falling. Finally, under the action of force, the two sets of buffer connecting rods 405 will contract synchronously. With the cooperation of the slide rail 401 and the slide block 402, the sliding block 403 is pushed to move inside the hollow bracket, which pressurizes the buffer rubber column 404. The three sets of structures form a multi-level buffer structure, which effectively releases the buffering force of the elevator falling. Compared with a single structure, its buffering effect is significantly improved.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
