Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a buffer guide rail bracket and an elevator. Background Art
[0002] The elevator guide rail is an important component used to support and guide the operation of the elevator car, while the guide rail bracket plays the role of supporting and fixing the guide rail. The guide rail bracket is generally fixed to the elevator shaft wall by expansion bolts, forming a stable support system between them and the guide rail.
[0003] The existing conventional upper guide rail bracket is rigidly connected to the guide rail. The advantages of this solution are that the guide rail is easy to install and adjust, and the installation accuracy of the guide rail is easy to ensure. The disadvantage is that the car (or counterweight) shakes during operation, which touches the guide shoe vibration, especially the low-frequency vibration of the rolling guide shoe, which is directly transmitted to the shaft wall through the guide rail and the guide rail bracket. Due to the resonance principle, low-frequency noise may be generated in the room adjacent to the shaft, affecting the living comfort.
[0004] Another common solution is to add a buffer structure between the guide rail and the guide rail bracket. However, in order to ensure the buffering and vibration isolation performance, the buffer structure sacrifices some rigidity, resulting in insufficient support of the guide rail by the buffer device. When the elevator car runs at high speed, the balance of the car changes and the guide rail does not provide sufficient support to the car, resulting in increased shaking of the car, affecting the ride comfort of the car. Therefore, we need to propose a buffer guide rail bracket and an elevator to solve the above-mentioned problems. Utility Model Content

The buffer mechanism retains the support capacity of the guide rail 3 in all directions while ensuring the vibration buffering and blocking performance of the buffer guide rail bracket on the guide rail 3. Under the premise of ensuring the comfort of the car operation, the vibration of the guide rail 3 can be isolated from being transmitted to the shaft wall, and the influence of the vibration generated by the high-speed operation of the elevator on the room adjacent to the shaft can be reduced;
[0023] The buffer mechanism includes a first rubber plate 4, a second rubber plate 5 and a plurality of cylindrical rubbers 6. The first rubber plate 4 and the second rubber plate 5 are fixed in parallel on both sides of the second bracket 2, and one side of the first rubber plate 4 is in contact with the outer wall of the guide rail 3. The second bracket 2, the first rubber plate 4, the second rubber plate 5 and the guide rail 3 are connected by a plurality of bolts 7. The outer side of each bolt 7 is sleeved with a cylindrical rubber 6. The installation direction of the cylindrical rubber 6 is perpendicular to the installation direction of the first rubber plate 4. Through the buffer mechanism composed of the first rubber plate 4, the second rubber plate 5 and a plurality of buffer rubber tubes 601, the lateral force of the first rubber plate 4 and the second rubber plate 5 is borne by the cylindrical rubber 6, so as to prevent the vulcanized bonding positions of the first rubber plate 4 and the second rubber plate 5 from being frequently subjected to reciprocating forces and causing the vulcanized bonding layer to fall off, thereby ensuring the overall safety of the buffer guide rail 3 bracket structure;
[0024] The first rubber plate 4 and the second rubber plate 5 are both composed of a rubber sheet 402 and a steel plate 401. The rubber sheet 402 and the steel plate 401 are bonded by vulcanization. The rubber sheet 402 of the first rubber plate 4 and the rubber sheet 402 of the second rubber plate 5 are fixed on both sides of the second bracket 2, and the steel plate 401 of the first rubber plate 4 and the steel plate 401 of the second rubber plate 5 are symmetrically arranged with the second bracket 2 as the center. The length and width of the steel plate 401 of the first rubber plate 4 are the same as those of the second rubber plate 5, but there is a difference in the openings. The steel plate 401 provides the first rubber plate 4 and the second rubber plate 5 with support hardness, thereby improving the support force for the second bracket 2, so that the lateral force of the first rubber plate 4 and the second rubber plate 5 is borne by the cylindrical rubber 6, so as to prevent the vulcanized bonding position of the rubber sheet 402 and the steel plate 401 from being frequently subjected to reciprocating force, thereby preventing the vulcanized bonding layer of the rubber sheet 402 and the steel plate 401 from falling off due to fatigue, thereby ensuring the overall safety of the buffer guide bracket structure.

The outside of the buffer rubber tube 601 is sleeved with an outer shell 603, and the upper and lower ends of the outer shell 603 are fixed to the upper and lower ends of the inner shell 602, so that a buffer rubber tube is cast between the inner shell 602 and the outer shell 603, which can buffer and block the radial vibration of 360°. In the axial direction of the cylindrical rubber, when the first rubber plate 4 and the second rubber plate 5 absorb vibration and are compressed a certain distance, the steel sleeve of the outer shell 603 can provide rigid support for the guide rail 3 in the axial direction, limit the excessive displacement of the guide rail 3 and thus affect the comfort of the car operation, thereby ensuring the safe operation of the car.
[0027] The length of the buffer rubber tube 601 is greater than the sum of the thickness of the rubber sheet 402 of the first rubber plate 4 and the thickness of the rubber sheet 402 of the second rubber plate 5. The inner shell 602 and the outer shell 603 are both configured as steel pipes to increase the lateral support force for the first rubber plate 4 and the second rubber plate 5.
