Description

Technical Field

[0001] This utility model relates to the field of guide shoe technology, and in particular to a roller guide shoe for villa elevators. Background Technology

[0002] Guide shoes are sliding nylon blocks between the elevator guide rails and the car. They secure the car to the guide rails, allowing it to move only up and down. Each elevator car is equipped with four sets of guide shoes, installed on both sides of the upper beam and below the safety gear seat at the bottom of the car. Four sets of counterweight guide shoes are installed at the bottom and top of the counterweight beam. The guide shoes fixed to the car can move back and forth along the fixed guide rails installed on the building shaft walls, preventing the car from tilting or swaying during operation. Elevator guide shoes are divided into rolling guide shoes and sliding guide shoes. Rolling guide shoes, also known as roller guide shoes, use 3 or 6 wheels that are engaged with the guide rails. With the development of cities in my country, more and more people are living in houses equipped with elevators. However, due to the limited area of ​​the houses, these elevators are generally small in size, and therefore the guide shoes used with them are also small in size. As a result, the shock absorption effect of the guide shoes is often not very good. Therefore, there is a need for roller guide shoes that are suitable for villa elevators and have a better shock absorption effect. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1 to 2 This utility model provides a roller guide shoe for a villa elevator, characterized in that it includes:

[0025] Base plate 1;

[0026] Mounting bracket 2 is installed on top of the base plate 1;

[0027] The first wheel assembly 3 includes a first roller 301, a first swing arm 302, and a first elastic damping mechanism 4. The first roller 301 is rotatably connected to the first swing arm 302 via a first rotating shaft 303. The first swing arm 302 is provided with a first rotating part 304, which is rotatably connected to the mounting bracket 2. The first elastic damping mechanism 4 is installed on the upper part of the first swing arm 302, and one end of the first elastic damping mechanism 4 is detachably connected to the mounting bracket 2. The first rotating shaft 303 is disposed between the first elastic damping mechanism 4 and the first rotating part 304.

[0028] The second wheel assembly 5 includes a second roller 501, a second swing arm 502, and a second elastic damping mechanism 6.

The second elastic damping mechanism 6 passes through the upper part of the second swing arm 502, and one end of the second elastic damping mechanism 6 is detachably connected to the mounting bracket 2. The second rotating shaft 503 is disposed between the second elastic damping mechanism 6 and the second rotating part 504. There are two second wheel assemblies 5, which are symmetrically arranged on both sides of the first wheel assembly 3.

[0029] This utility model embodiment provides a roller guide shoe for a villa elevator, characterized by comprising: a base plate 1, a mounting bracket 2, a first wheel set 3, and a second wheel set 5; two second wheel sets 5 are symmetrically arranged on both sides of the first wheel set 3, and the two second wheel sets 5 and one first wheel set 3 cooperate to contact the guide rail. The base plate 1 is used to install on the elevator car. When the elevator is running, the first roller 301 and the second roller 501 abut against the guide rail. When the elevator car shakes, the base plate 1 shakes. At this time, under the action of the first elastic damping mechanism 4 and the first swing arm 302, the first roller 301 swings around the first rotating part 304 of the first swing arm 302 and always abuts against the elevator guide rail. Similarly, the second roller 501 swings around the second rotating part 504 of the second swing arm 502 and always abuts against the elevator guide rail. During this process, the first elastic damping mechanism 4 and the first swing arm 302... The second elastic damping mechanism 6 can play a damping role, making the elevator ride more comfortable for users. The first rotating shaft 303 is disposed between the first elastic damping mechanism 4 and the first rotating part 304. The first roller 301 is mounted on the first rotating shaft 303, which makes the distance from the first elastic damping mechanism 4 to the first rotating part 304 greater than the distance from the first roller 301 to the first rotating part 304. When the first roller 301 swings around the first rotating part 304 of the first swing arm 302, the lever arm of the first elastic damping mechanism 4 is greater than the lever arm of the first roller 301, thereby enabling the first elastic damping mechanism 4 to play a better damping role in a limited space. Similarly, the second rotating shaft 503 disposed between the second elastic damping mechanism 6 and the second rotating part 504 enables the second elastic damping mechanism 6 to play a better damping role in a limited space.

[0030] In a further embodiment of this invention, the first elastic damping mechanism 4 includes a first screw 401, a first adjusting nut 402, and a first damping spring 403.

[0031] In this embodiment, the first elastic damping mechanism 4 includes a first screw 401, a first adjusting nut 402, and a first damping spring 403. The first damping hole 305 is an oblong hole. When the first roller 301 swings around the first rotating part 304 of the first swing arm 302, the first screw 401 is fixed on the mounting bracket 2, and the first swing arm 302 compresses the first damping spring 403, thereby limiting the swing of the first swing arm 302 and thus achieving the effect of damping. The first adjusting nut 402 is threadedly connected to the first screw 401. Tightening the first adjusting nut 402 can adjust the relative position of the first adjusting nut 402 on the first screw 401, thereby adjusting the distance between the first adjusting nut 402 and the first swing arm 302, which can adjust the elasticity of the first damping spring 403, thus providing a better damping effect for elevator cars of different sizes.

[0032] In a further embodiment of this invention, the first elastic damping mechanism 4 further includes a first damping pad 404, which is sleeved on the first screw 401 and disposed between the first adjusting nut 402 and the first damping spring 403.

[0033] In this embodiment, the first elastic damping mechanism 4 further includes a first damping pad 404. The first damping pad 404 is disposed between the first adjusting nut 402 and the first damping spring 403, which can reduce the vibration between the first adjusting nut 402 and the first damping spring 403 during operation and can prevent the first adjusting nut 402 and the first damping spring 403 from being misaligned, thereby avoiding malfunction.

[0034] In a further embodiment of this invention, the lower part of the first swing arm 302 extends laterally to form a first limiting protrusion 306.

The position of the first limiting protrusion 306 corresponds to the position of the base plate 1. The first limiting protrusion 306 can limit the swing amplitude of the first swing arm 302, which can prevent the swing amplitude of the first swing arm 302 from being too large and excessively compressing the first damping spring 403, causing the first damping spring 403 and the first adjusting nut 402 to detach from the first screw 401, thus creating a safety hazard.

[0036] In a further embodiment of this invention, the first limiting protrusion 306 is provided with a first limiting hole (not shown in the figure), and the first wheel set 3 further includes a first limiting rod 308, which is threadedly connected to the first limiting hole and is located on the upper part of the base plate 1.

[0037] In this embodiment, a first limiting hole is provided on the first limiting protrusion 306, and the first limiting rod 308 is threadedly connected to the first limiting hole. The lower end of the first limiting rod 308 is located between the first limiting protrusion and the base plate 1. The first limiting rod 308 can limit the swing amplitude of the first swing arm 302. Twisting the first limiting rod 308 can adjust the distance from the lower end of the first limiting rod 308 to the first limiting protrusion, thereby adjusting the maximum swing amplitude of the first swing arm 302.

[0038] In a further embodiment of this invention, the second elastic damping mechanism 6 includes a second screw 601, a second adjusting nut 602, and a second damping spring 603. The upper part of the second swing arm 502 is provided with a second damping hole 505. The second screw 601 is inserted into the second damping hole 505. The first end of the second screw 601 is threadedly connected to the mounting bracket 2. The second adjusting nut 602 is threadedly connected to the second end of the second screw 601. The second damping spring 603 is sleeved on the second screw 601 and is disposed between the second swing arm 502 and the second adjusting nut 602.

[0039] In this embodiment, the second elastic damping mechanism 6 includes a second screw 601, a second adjusting nut 602, and a second damping spring 603. The second damping hole 505 is an oblong hole. When the second roller 501 swings around the second rotating part 504 of the second swing arm 502, the second screw 601 is fixed on the mounting bracket 2, and the second swing arm 502 compresses the second damping spring 603, thereby limiting the swing of the second swing arm 502 and thus achieving the effect of damping. The second adjusting nut 602 is threadedly connected to the second screw 601. Tightening the second adjusting nut 602 can adjust the relative position of the second adjusting nut 602 on the second screw 601, thereby adjusting the distance between the second adjusting nut 602 and the second swing arm 502, which can adjust the elasticity of the second damping spring 603, thus providing a better damping effect for elevator cars of different sizes.

[0040] In a further embodiment of this invention, the second elastic damping mechanism 6 further includes a second damping pad 604, which is sleeved on the second screw 601 and disposed between the second adjusting nut 602 and the second damping spring 603.

[0041] In this embodiment, the second elastic damping mechanism 6 further includes a second damping pad 604. The second damping pad 604 is disposed between the second adjusting nut 602 and the second damping spring 603, which can reduce the vibration between the second adjusting nut 602 and the second damping spring 603 during operation and can prevent misalignment of the second adjusting nut 602 and the second damping spring 603, thereby avoiding malfunction.

[0042] In a further embodiment of this invention, the lower part of the second swing arm 502 extends laterally to form a second limiting protrusion 506.

[0043] In this embodiment, the lower part of the second swing arm 502 extends to the side to form a second limiting protrusion 506. The position of the second limiting protrusion 506 corresponds to the position of the base plate 1. The second limiting protrusion 506 can limit the swing amplitude of the second swing arm 502, which can prevent the swing amplitude of the second swing arm 502 from being too large and excessively compressing the second damping spring 603, causing the second damping spring 603 and the second adjusting nut 602 to disengage from the second screw 601, thus creating a safety hazard.

[0044] In a further embodiment of this invention, the second limiting protrusion 506 is provided with a second limiting hole (not shown in the figure), and the second wheel set 5 further includes a second limiting rod 508, which is threadedly connected to the second limiting hole and is located on the upper part of the base plate 1.

The lower end of the second limiting rod 508 is located between the second limiting protrusion and the base plate 1. The second limiting rod 508 can limit the swing amplitude of the second swing arm 502. Twisting the second limiting rod 508 can adjust the distance from the lower end of the second limiting rod 508 to the second limiting protrusion, thereby adjusting the maximum swing amplitude of the second swing arm 502.
