Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator parts technology, and in particular to a damper for roller guide shoes. 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 has 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. Existing roller guide shoes generally use shock-absorbing springs to dampen vibrations and ensure smooth car operation. However, shock-absorbing springs can only reduce vibrations in the axial direction, but elevators generate vibrations in all directions during operation, and shock-absorbing springs often cannot provide effective damping in other directions. Therefore, a damper that can provide damping in all directions is needed. Utility Model Content

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.
[0023] See Figures 1 to 2 This utility model embodiment provides a damper for a roller guide shoe, characterized in that it includes:
[0024] Mounting bracket 1 is provided with mounting part 101, which is used to connect with the mounting frame of roller guide shoe, and mounting bracket 1 has a first connecting surface 102;
[0025] The connecting bracket 2 is provided with a connecting part 201, which is used to connect with the connecting arm of the roller guide shoe. The connecting bracket 2 has a second connecting surface 202.
[0026] The elastic damping element 3 is fixedly connected to the first connecting surface 102 at its top and to the second connecting surface 202 at its bottom.
[0027] This utility model embodiment provides a damper for roller guide shoes, characterized in that it includes: a mounting bracket 1, a connecting bracket 2, and an elastic damping element 3, wherein the elastic damping element 3 is made of an elastic material, such as rubber; during installation, the mounting bracket 1 is mounted on the mounting frame of the roller guide shoe, and the connecting arm with the roller mounted is mounted on the connecting bracket 2. At this time, the connecting arm is connected to the mounting frame through the damper. During elevator operation, the roller abuts against the guide rail. When the elevator shakes, the elevator car drives the mounting frame to shake. At this time, under the action of the damper, the roller always abuts against the elevator guide rail. During this process, the elastic damping element 3 can play a shock absorption role, making the user's elevator ride more comfortable; compared with conventional shock-absorbing springs, the elastic damping element 3 can reduce the vibration of the roller in any direction, and can play a better shock absorption role.
[0028] In a further embodiment of this invention, the mounting bracket 1 includes a first damping plate 103, one side of which extends downward to form a mounting plate 104. The first damping plate 103 has the first connecting surface 102, and the mounting plate 104 is provided with the mounting portion 101.
[0029] In this embodiment, one side of the first damping plate 103 extends downward to form a mounting plate 104. The lower part of the first damping plate 103 has the first connecting surface 102. The top of the elastic damping member 3 is connected to the lower part of the first damping plate 103, and the bottom of the elastic damping member 3 is connected to the connecting bracket 2. This ensures that the position of the mounting part 101, the position of the elastic damping member 3, and the position of the connecting bracket 2 are all located at the lower part of the first damping plate 103. When the elevator sways, the mounting bracket 1 only connects to the roller through the mounting part 101. When the connecting bracket 2 and the mounting bracket 1 move relative to each other, the mounting bracket 1 tends to rotate around the mounting part 101 under the drive of the connecting bracket 2. By setting the mounting part 101 and the connecting bracket 2 on the same side of the first damping plate 103, the lever arm of the connecting bracket 2 can be reduced when the mounting bracket 1 tends to rotate around the mounting part 101, thereby reducing the load on the mounting part 101, thus improving the structural strength of the mounting bracket 1 and increasing its service life.
[0030] In a further embodiment of this invention, the mounting part 101 is a mounting threaded hole, and there are two mounting threaded holes, which are symmetrically distributed on the mounting plate 104.
[0031] In this embodiment, the mounting part 101 is a mounting threaded hole, and the mounting bracket 1 can be installed on the mounting bracket of the roller guide shoe by bolts engaging the mounting threaded hole. The structure is simple, easy to assemble, and improves assembly convenience.
[0032] In a further embodiment of this invention, the connecting bracket 2 includes a second damping plate 203, with two connecting plates 204 extending downward from opposite sides of the second damping plate 203. The second damping plate 203 has a second connecting surface 202, and the connecting plate 204 is provided with the connecting portion 201.
[0033] In this embodiment, the second damping plate 203 extends downward on both sides to form two connecting plates 204, such that the two connecting plates 204 are arranged opposite to each other and the two connecting parts 201 are arranged opposite to each other. During installation, the connecting arm of the roller guide shoe is arranged between the two connecting plates 204 and can be rotatably connected to the two connecting parts 201. By setting the two connecting plates 204 and the two connecting parts 201, the connecting arm can be supported from both sides, thereby preventing the connecting arm from deflecting, thus providing better support and improving service life.
[0034] In a further embodiment of this invention, the connecting part 201 is a connecting through hole, and there are two connecting through holes, which are respectively disposed on the two connecting plates 204.
[0035] In this embodiment, the connecting part 201 is a connecting through hole. The connecting arm of the roller guide shoe is rotatably connected to the connecting plate 204 through the connecting through hole via a rotating shaft. The structure is simple, easy to assemble, and improves assembly convenience.
[0036] In a further embodiment of this invention, the elastic damping element 3 is in the shape of a cuboid.
[0037] In this embodiment, the elastic damping element 3 is in the shape of a cuboid, and the overall shape of the elastic damping element 3 is a flat cuboid, which is convenient for processing and saves production costs.
[0038] In a further embodiment of this invention, the upper surface of the elastic damping member 3 is a rectangular surface, the first connecting surface 102 is a rectangular surface, and the ratio of the area of the upper surface of the elastic damping member 3 to the area of the first connecting surface 102 is 0.3 to 0.4.
[0039] In this embodiment, the ratio of the upper surface area of the elastic damping member 3 to the area of the first connecting surface 102 is 0.3 to 0.4. If the upper surface area of the elastic damping member 3 is too large, it will increase the difficulty of attaching the elastic damping member 3 to the first connecting surface 102. If the upper surface area of the elastic damping member 3 is too small, the connection strength between the elastic damping member 3 and the first connecting surface 102 cannot be guaranteed. Therefore, when the ratio of the upper surface area of the elastic damping member 3 to the area of the first connecting surface 102 is 0.3 to 0.4, the installation difficulty can be reduced while ensuring the connection strength between the elastic damping member 3 and the first connecting surface 102.
[0040] In a further embodiment of this invention, the lower surface of the elastic damping member 3 is a rectangular surface, the second connecting surface 202 is a rectangular surface, and the ratio of the area of the upper surface of the elastic damping member 3 to the area of the second connecting surface 202 is 0.6 to 0.7.
[0041] In this embodiment, the ratio of the lower surface area of the elastic damping member 3 to the area of the second connecting surface 202 is 0.6 to 0.7. If the lower surface area of the elastic damping member 3 is too large, it will increase the difficulty of attaching the elastic damping member 3 to the second connecting surface 202. If the lower surface area of the elastic damping member 3 is too small, the connection strength between the elastic damping member 3 and the second connecting surface 202 cannot be guaranteed. Therefore, when the ratio of the lower surface area of the elastic damping member 3 to the area of the second connecting surface 202 is 0.6 to 0.7, the installation difficulty can be reduced while ensuring the connection strength between the elastic damping member 3 and the second connecting surface 202.
[0042] In a further embodiment of this invention, the ratio of the thickness of the elastic damping member 3 to the thickness of the first damping plate 103 is 1.6 to 1.7.
[0043] In this embodiment, the ratio of the thickness of the elastic damping member 3 to the thickness of the first damping plate 103 is 1.6 to 1.7. If the thickness of the elastic damping member 3 is too small, it cannot effectively reduce vibration, and the first connecting surface 102 and the second connecting surface 202 may collide, causing a safety hazard. If the thickness of the elastic damping member 3 is too large, it cannot effectively limit the swing amplitude of the connecting bracket 2 relative to the mounting bracket 1, which may cause the side of the connecting bracket 2 to collide with the mounting bracket 1, causing a safety hazard. Therefore, when the ratio of the thickness of the elastic damping member 3 to the thickness of the first damping plate 103 is 1.6 to 1.7, the safety hazard can be effectively reduced.
[0044] In a further embodiment of this invention, the ratio of the thickness of the elastic damping member 3 to the thickness of the second damping plate 203 is 1.6 to 1.7.
[0045] In this embodiment, the ratio of the thickness of the elastic damping member 3 to the thickness of the second damping plate 203 is 1.6 to 1.7. If the thickness of the elastic damping member 3 is too small, it cannot effectively reduce vibration, and the first connecting surface 102 and the second connecting surface 202 may collide, causing a safety hazard. If the thickness of the elastic damping member 3 is too large, it cannot effectively limit the swing amplitude of the connecting bracket 2 relative to the mounting bracket 1, which may cause the side of the connecting bracket 2 to collide with the mounting bracket 1, causing a safety hazard. Therefore, when the ratio of the thickness of the elastic damping member 3 to the thickness of the second damping plate 203 is 1.6 to 1.7, the safety hazard can be effectively reduced.
