Technical Field

[0001] This utility model relates to the field of traction machine technology, specifically to a vibration damping base for an elevator traction machine. Background Technology

[0002] Traction machine vibration damping base is a key component in elevator systems used to reduce vibration and noise transmission. Its design directly affects the smoothness of elevator operation and the comfort of the building structure.

[0003] Chinese patent CN220523171U discloses an electromagnetic braking mechanism for an elevator traction machine; when the spring needs to be replaced, the threaded column is first rotated to move it upward to support the upper plate of the machine base, and then the bolts are removed to slide the column out of the slide groove, thereby realizing the function of removing the shock-absorbing spring.

[0004] However, the above-mentioned existing technology has the following drawbacks: when replacing the shock absorber spring, it is necessary to disassemble it together with the support column. Since the support column and the spring together have a large mass, they are not convenient to move, which increases the burden during the spring disassembly process; in addition, the shock absorber spring in the above-mentioned existing technology is a whole unit, and if part of it is damaged, the whole unit needs to be replaced, which increases the replacement cost of the shock absorber spring. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a vibration damping base for an elevator traction machine.

[0007] The telescopic mechanism includes an upper plate, a lower plate, a piston cylinder, a column, an upper fixing plate, and a lower fixing plate; the upper and lower plates are symmetrically arranged; the upper fixing plate is connected to the top of the piston cylinder; the lower fixing plate is connected to the bottom of the column; the upper fixing plate is connected to the upper plate by bolts; the lower fixing plate is connected to the lower plate by bolts; multiple sets of piston cylinders and columns are provided and distributed circumferentially; mounting plates are connected to both the column and the piston cylinder; an upper support plate is connected to the column; a lower support plate is connected to the piston cylinder.

[0010] Preferably, the upper plate has an air chamber symmetrical about the spring assembly inside; the air chamber is connected to the piston cylinder; the upper plate is connected to an air pipe that is connected to the air chamber; the air pipe is positioned towards the spring assembly.

[0012] Preferably, one of the two menisci that are spliced ​​together has an insert block connected to its splicing surface; the other menisci has a slot on its splicing surface.

[0013] Preferably, the support mechanism includes an indicator ring, a nut block, a screw, and an indicator post; the indicator post is connected to the top of the screw; the indicator post is connected to the bottom of the upper support plate; the screw is slidably connected to the lower support plate; the indicator ring is sleeved on the indicator post; the nut block is threadedly connected to the screw; and the nut block and the indicator ring are connected by a connecting rod.

This significantly reduces the burden during replacement and also reduces replacement costs.

[0018] By incorporating a support mechanism, the piston cylinder and column can be temporarily limited, allowing them to support the upper plate and preventing imbalance of the damping base during spring mechanism replacement. Simultaneously, it prevents excessive buffering of the damping base and provides some protection for the damping springs. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-3 as well as Figure 6 As shown, the present invention proposes an elevator traction machine vibration damping base, which includes a telescopic mechanism, a spring mechanism, and a support mechanism.

[0029] The telescopic mechanism includes an upper plate, a lower plate, a piston cylinder, a column, an upper fixed plate, and a lower fixed plate; the upper and lower plates are symmetrically arranged; the upper fixed plate is connected to the top of the piston cylinder; the lower fixed plate is connected to the bottom of the column; the upper fixed plate is connected to the upper plate by bolts; the lower fixed plate is connected to the lower plate by bolts; multiple sets of piston cylinders and columns are provided and distributed circumferentially; mounting plates are connected to both the column and the piston cylinder; an upper support plate is connected to the column; a lower support plate is connected to the piston cylinder; the upper plate has air chambers symmetrical about the spring assembly inside; the air chambers communicate with the piston cylinder; the upper plate is connected to an air pipe communicating with the air chambers; the air pipe is positioned towards the spring assembly.

[0030] The spring mechanism has two sets and is detachably connected to the mounting plate for vibration damping and buffering.

[0031] The support mechanism consists of two sets connected between the upper and lower support plates, providing temporary support for the telescopic mechanism.

[0032] In this embodiment, during the vibration reduction process, the upper plate presses down on the piston cylinder, causing the piston cylinder to move downward. The downward movement of the piston cylinder compresses the spring mechanism, thereby playing a vibration reduction and buffering role. During the reciprocating up and down movement of the piston cylinder, the column performs piston movement inside the piston cylinder, which can squeeze the air inside the piston cylinder into the air chamber and finally spray it out through the air pipe. The sprayed gas blows towards the spring mechanism, which can accelerate the airflow around the spring mechanism, reduce the dust accumulated on the spring mechanism, and at the same time help the spring mechanism cool down.

[0033] The support mechanism can provide temporary support for the piston cylinder when the spring mechanism is disassembled, thereby limiting the relative movement between the piston cylinder and the column and providing some support for the upper plate to prevent the entire vibration damping base from losing its balance.

[0034] Example 2

[0035] like Figure 4-5 As shown, this utility model proposes an elevator traction machine vibration damping base. Compared with Embodiment 1, this embodiment also details the structure of the spring mechanism. The spring mechanism includes a damping spring, a meniscus, and an arc-shaped plate. Two menisci are provided and are respectively connected to the two ends of the damping spring. The menisci of the two sets of spring mechanisms are spliced ​​together to form a ring and are locked onto the surface of the column and piston cylinder. The arc-shaped plate is provided at the joint of the menisci. The arc-shaped plate, the menisci, and the mounting plate are connected by bolts. One of the spliced ​​menisci has an insert block connected to its splicing surface. The other menisci has a slot on its splicing surface.

[0036] In this embodiment, the insert and slot work together to facilitate the quick splicing of the two menisci to form a complete ring. The arc plate, with bolts, can simultaneously fix the two menisci to the mounting plate, thus realizing the installation function of the spring mechanism. When one of the damping springs wears out and needs to be replaced, the menisci and damping spring can be removed from the column and piston cylinder by removing the bolts, without having to remove them together with the column and piston cylinder, making it convenient to disassemble and replace the damping spring. In addition, the damping and buffering effect of the two damping springs in this embodiment is the same as that of a traditional single spring. Therefore, the mass and volume of one damping spring are much smaller than that of a traditional spring, which further facilitates the replacement of the damping spring. When one is damaged, only one needs to be replaced. Since the mass and volume of a single damping spring are much smaller than that of a traditional spring, its cost is also lower, thereby reducing the replacement cost of the damping spring.

[0037] Example 3

[0038] like Figure 7As shown, this utility model proposes an elevator traction machine vibration damping base. Compared with Embodiment 2, this embodiment further details the structure of the support mechanism. The support mechanism includes an indicator ring, a nut block, a screw, and an indicator post. The indicator post is connected to the top of the screw. The indicator post is connected to the bottom of the upper support plate. The screw is slidably connected to the lower support plate. The indicator ring is sleeved on the indicator post. The nut block is threadedly connected to the screw. The nut block and the indicator ring are connected by a connecting rod. A hole is provided on the lower support plate. The bottom end of the screw passes through the hole and is connected to a limit block. The indicator post has a scale to indicate the descent height of the nut block. An elastic cotton layer is provided at the bottom of the nut block for vibration damping and buffering.

[0039] In this embodiment, by rotating the nut block, the nut block moves up and down along the screw, causing the indicator ring to slide on the indicator post. By using the indicator ring in conjunction with the scale on the indicator post, the distance between the nut block and the lower support plate can be accurately adjusted. The distance between the nut block and the lower support plate is the maximum distance that the piston cylinder can move downward, which is the maximum vibration amplitude of the vibration damping base. By ensuring that the maximum vibration amplitude of the vibration damping base is less than the maximum compression of the vibration damping spring, excessive buffering of the vibration damping base can be avoided, thus providing a certain degree of protection for the vibration damping spring. When the nut block collides with the lower support plate, the elastic cotton layer can act as a buffer, preventing a hard collision between the two.

[0040] When the spring mechanism needs to be replaced, the nut block can be rotated to contact the lower support plate. At this time, the piston cylinder cannot move down, which can provide temporary support for the upper plate and prevent the vibration damper base from becoming unbalanced during the replacement of the spring mechanism.

[0041] In summary, when this utility model is used, during the vibration damping process, the upper plate will press down on the piston cylinder, causing the piston cylinder to move downward. The downward movement of the piston cylinder will compress the vibration damping spring, thereby playing a vibration damping and buffering role. During the reciprocating up and down movement of the piston cylinder, the column performs piston movement inside the piston cylinder, which can squeeze the air inside the piston cylinder into the air chamber, and finally spray it out through the air pipe. The sprayed gas blows towards the vibration damping spring, which can accelerate the airflow around the vibration damping spring, reduce the dust accumulated on the vibration damping spring, and at the same time help cool down the vibration damping spring.

[0042] When one of the damping springs is damaged and needs to be replaced, first rotate the nut block until it contacts the lower support plate. At this time, the piston cylinder cannot move down, which can provide temporary support for the upper plate and prevent the damper base from becoming unbalanced during the replacement of the spring mechanism. Then, remove the knob bolt to separate the arc plate from the meniscus. By sliding the meniscus to separate it from the mounting plate, the damping spring can be removed from the column and piston cylinder. The meniscus on the new damping spring is spliced ​​with the original meniscus on the column and piston cylinder. Then, the arc plate and bolts are used to connect them, which realizes the function of replacing the damping spring. It is not necessary to remove the column and piston cylinder together, which facilitates the disassembly and replacement of the damping spring. Since the mass and volume of one damping spring are much smaller than those of a traditional spring, the burden of replacing the damping spring is reduced. When one is damaged, only one needs to be replaced. Since the mass and volume of one damping spring are much smaller than those of a traditional spring, its cost is also lower than that of a traditional spring, thus reducing the replacement cost of the damping spring.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
