Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of elevator installations, in particular to the technical field of vibration-damped guide rail fastening systems. [Background technology]
[0002] The main vertical movement structures of an elevator are a car and a counterweight frame. Here, the car provides a passenger space, and the counterweight frame, as a weight structure, must always face the car from above and below so as to reduce the operating load and smoothly accelerate the car. The car and the counterweight frame usually need to be used together with a guide rail during operation. The guide rail is a guide structure applied to elevator operation, such as the guide rail of a prefabricated elevator disclosed in utility model publication number CN220351420U, and is generally fixed in the vertical direction of the hoistway to provide a guide for the car and the counterweight frame for vertical linear movement.
[0003] A guide rail is usually connected indirectly to a hoistway by a guide rail fixing system. Conventional guide rail fixing systems are generally directly fixed to the hoistway by fasteners, such as the steel structure elevator hoistway guide rail fixing device disclosed in utility model publication number CN220300071U and the guide rail bracket in elevator hoistway disclosed in invention publication number CN112299194B. This type of installation method may cause sudden vibrations during elevator operation. It is realized that when the car travels to a certain fixed point, the person in the car can feel the car shaking strongly. This is because the vibration curve of the car generated at a certain elevated height greatly exceeds the standard, which is usually caused by the rail fixing system.
[0004] For this reason, in the past, elevators were inspected periodically by relevant personnel to ensure that each mounting part of the elevator was in good condition, but it was difficult to reduce the adverse effects of the guide rail fixing system on building vibration.

[0005] [Patent Document 1] China Utility Model Publication CN220351420U [Patent Document 2] China Utility Model Publication CN220300071U [Patent Document 3] China Patent Publication CN112299194B Summary of the Invention [Problem to be solved by the invention]
[0006] The present invention aims to solve the problems in the prior art, and provide a vibration-damping guide rail fixing system that effectively reduces the adverse effects on buildings caused by vibrations during elevator operation, ensures the stability of the car's landing on the floor, and improves comfort during the elevator's operation. [Means for solving the problem]
[0007] In order to achieve the above-mentioned object, the present invention provides a vibration-damping guide rail fixing system comprising a bracket including a base plate and a stay, an elastic buffer pad, an angle, and a pressure plate, the bracket being provided perpendicular to the base plate and removably connected to the hoistway wall by a fastener, the space between the hoistway wall and the bracket being buffered by an elastic buffer pad provided on the stay, one segment of the angle being removably connected to the base plate by a fastener, and the other segment having a plurality of pressure plates removably attached thereto by fasteners, and each pressure plate can firmly clamp the guide rail together with the angle.
[0008] Preferably, burrings bent back toward the stays are provided on opposite side edges of the base plate, and the stays are fixed between the two burrings.
[0009] Preferably, the stay has a side facing the hoistway wall and a side facing away from the hoistway wall overlaid with an elastic buffer pad which is removably connected to the stay by a fastener.
[0010] Preferably, the two elastic buffer pads are overlapped on the sides facing away from the stays with partition plates removably connected thereto by fasteners.
[0011] Preferably, the elevator further includes a channel steel that is pre-embedded in the elevator shaft wall and has a notch facing outward, and inner extension sides (71) are provided extending opposite to the two long sides of the notch, and the stay, inner extension sides, two elastic buffer pads and two partition plates are removably connected by a plurality of fasteners.
[0012] Preferably, the two elastic buffer pads are arranged with the pad body mesh-shaped recesses distributed toward the surface of the stay and / or the attached partition plate.
[0013] Preferably, grooved network recesses are distributed on the outer wall of the channel steel.
[0014] Preferably, a plurality of reinforcing ribs are further provided on the side of the base plate on which the stays are provided.
[0015] Preferably, an anti-slip mat is provided on the side of each of the pressure plates facing the angle.
[0016] Preferably, the positioning holes in the angle through which the fasteners pass are all oblong holes.
[0017] Beneficial Effects of the Invention 1) By combining the bracket, elastic buffer pad, angle and pressure plate, the guide rail can be supported and fixed by the bracket, and under the condition that there is no need to adjust the position of the connection port of the guide rail, the elastic buffer pad isolated between the bracket and the hoistway wall can effectively reduce the adverse impact on the building caused by the vibration caused by the elevator's operation, ensure the stability of the car's landing on the floor, and improve the comfort during the elevator operation. The overall structure is simple, convenient to install, and versatile, and can be adjusted and installed according to different hoistway dimensions and elevator guide rail specifications, which is of practical value and has been applied to various elevator construction projects and verified by actual applications.
[0018] 2) By fixing the stays using a pair of burrings provided on the base plate and providing the partition plate, elastic buffer pad and stay in that order, the mounting stability of the elastic buffer pad can be ensured and the service life of the elastic buffer pad can be extended.
[0019] 3) By embedding a channel steel with an outward notch in the elevator shaft wall in advance and by making the positioning holes in the angles through which the fasteners pass all oval holes, it becomes easy to adjust the installation position of the guide rail according to the required small range.
[0020] 4) The elastic buffer pad has mesh-like recesses in a pad body distributed toward the surface of the stay and / or the attached partition plate, and also has mesh-like recesses in a groove body distributed on the outer wall of the channel steel, which effectively improves the surface roughness of the elastic buffer pad and the channel steel and prevents the elastic buffer pad and the channel steel from automatically displacing each other. Furthermore, when the elastic buffer pad is subjected to pressure, the notches on the surface further expand along the textured openings, thereby pushing out the air between the elastic buffer pad and the partition plate and / or the stay and generating negative pressure, which further improves the mounting stability of the elastic buffer pad.
[0021] The features and advantages of the invention will now be explained in more detail by way of example and with reference to the drawings. [Brief description of the drawings]
