Description

[Technical Field]

[0001] The present invention relates to the technical field of elevator installations, and 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 the car and the counterweight frame. Here, the car provides passenger space, and the counterweight frame, as a weight structure, must always face the car from above and below to reduce the operating load and enable smooth acceleration of the car. The car and the counterweight frame usually require the use of guide rails during operation. Guide rails are guide structures used in elevator operation, such as the guide rails of the modular elevator disclosed in utility model publication number CN220351420U. Guide rails are generally fixed vertically in the hoistway to provide a guide for the car and the counterweight frame for vertical linear movement.

[0003] Guide rails are typically indirectly connected to the hoistway using a guide rail fastening system. Conventional guide rail fastening systems are typically directly fixed to the hoistway using fasteners, such as the steel structure elevator hoistway guide rail fastening device disclosed in utility model publication number CN220300071U and the guide rail bracket in the elevator hoistway disclosed in invention publication number CN112299194B. This type of installation can cause sudden vibrations during elevator operation. This is manifested as passengers in the car feeling a strong car sway when the car reaches a certain fixed point. This is because the car's vibration curve at a certain elevated height significantly exceeds the standard, which is usually due to the rail fastening system.

[0004] For this reason, elevators are conventionally inspected periodically by relevant personnel to ensure that each elevator attachment is in good condition, but it is difficult to reduce the adverse effects of the guide rail fixing system on building vibrations.

[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 of the prior art and provide a vibration-damping guide rail fixing system that effectively reduces the adverse effects on buildings caused by elevator vibrations, ensures stable landing of the car on the floor, and improves comfort during elevator operation. [Means for solving the problem]

[0007] In order to achieve the above 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 disposed 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 disposed 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, elastic buffer pads are superimposed on the side of the stay facing the hoistway wall and the side facing away from the hoistway wall, and are removably connected by fasteners.

[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 mesh-like recesses of the pad body 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 where the stays are provided.

[0015] Preferably, an anti-slip mat is provided on each of the pressing plates on the side 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 retaining plate, the guide rail can be supported and fixed by the bracket, and there is no need to adjust the position of the guide rail connection port. The elastic buffer pad isolated between the bracket and the hoistway wall effectively reduces the adverse impact of elevator vibration on the building, ensures the stability of the car's landing, and improves comfort during elevator operation. The overall structure is simple, easy to install, and versatile, and can be adjusted and installed according to different hoistway dimensions and elevator guide rail specifications. It has practical value and can be applied to various elevator projects and has been verified by actual applications.

[0018] 2) The stays are fixed using a pair of burrings provided on the base plate, and the partition plate, elastic buffer pad, and stay are provided in that order, thereby ensuring the stability of the attachment of the elastic buffer pad and extending its service life.

[0019] 3) By embedding channel steel with outward notches in the elevator shaft wall in advance, and by making the positioning holes through which each fastener passes in the angle into oblong 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 distributed along the surface of the stay and / or attached partition plate, and the grooves are distributed along the outer wall of the channel steel, which effectively improves the surface roughness of the elastic buffer pad and the channel steel and prevents automatic displacement between the elastic buffer pad and the channel steel. When the elastic buffer pad is subjected to pressure, the notches on the surface further expand along the textured openings, pushing out air between the pad and the partition plate and / or stay, generating negative pressure and further improving the installation 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 with reference to the drawings. [Brief explanation of the drawings]

One segment of the angle 3 is removably connected to the base plate 11 by fasteners 5, and the other segment has multiple pressure plates 4 removably attached thereto by fasteners 5. Each pressure plate 4, together with the angle 3, can firmly clamp a guide rail 9. Here, the bracket 1 is used to support and fix the guide rail 9, and the elastic buffer pad 2 is a rubber pad mounted between the bracket 1 and the elevator shaft wall 8 to reduce the impact of elevator vibrations on the building.

[0024] On both opposing edges of the base plate 11, burrings 111 are provided, each of which is folded back toward the stay 12, and the stay 12 is fixed between the two burrings 111.

[0025] Elastic buffer pads 2 detachably connected by fasteners 5 are superimposed on the side of the stay 12 facing the hoistway wall 8 and the side facing away from the hoistway wall 8 .

[0026] A partition plate 6 detachably connected by a fastener 5 is superimposed on the sides of the two elastic buffer pads 2 facing away from the stay 12 .

[0027] The elevator further includes a channel steel 7 that is pre-embedded in the elevator shaft wall 8 and has a notch facing outward, and inner extension sides 71 are provided extending opposite the two long sides of the notch, and the stay 12, inner extension sides 71, two elastic buffer pads 2, and two partition plates 6 are removably connected by a plurality of fasteners 5.
