Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to an elevator guide rail bracket with a vibration isolation function. Background Art

[0002] In elevator equipment, elevator guide rails are usually rigidly connected to the building wall through guide rail brackets. In this way, the vibration during elevator operation will be transmitted to the building wall through the guide rails, thereby generating noise. In order to avoid the vibration and noise generated during elevator operation from affecting residents, in the prior art, the guide rail bracket is set as a vibration isolation bracket. For example, a guide rail vibration isolation device disclosed in a Chinese invention patent with the publication number CN110844741B. The guide rail vibration isolation device includes a guide rail mounting member, a limit bracket, a limit bracket plate and a bracket, and also includes a first vibration isolation material and a second vibration isolation material. The guide rail mounting member is connected to the guide rail, the bracket is connected to the building wall body. The first vibration isolation material is arranged between the limit bracket plate and the guide rail mounting member, and the second vibration isolation material is arranged between the limit bracket plate and the limit bracket. When the elevator car transmits force to one side of the guide rail, the guide rail on the other side of the elevator car will also be subjected to force. The guide rail mounting member transmits the force to the first vibration isolation material and the second vibration isolation material, avoiding directly transmitting the force to the limit bracket plate, thereby achieving the purpose of vibration isolation and noise reduction.

[0003] In the prior art, for elevator guide rails with a vibration isolation function, the initial pre-pressure of the vibration isolation materials in the guide rail vibration isolation device is inconsistent, which easily leads to inconsistent acting forces between the guide rail vibration isolation devices on both sides of the elevator car and the guide rails on both sides, reducing the vibration isolation and noise reduction effects. At the same time, it is inconvenient to adjust the angle of the guide rail in the prior art, resulting in inconvenient installation. Summary of the Invention

[0004] To overcome the deficiencies of the prior art, the present invention provides an elevator guide rail bracket with a vibration isolation function to solve the technical problems of inconsistent pre-pressure of the vibration isolation materials in the elevator guide rail vibration isolation device and inconvenient adjustment of the guide rail angle in the prior art.

One end of the support cylinder 210 away from the support rod 220 is hingedly connected with the wall fixing plate 130 through a spherical hinge structure 131.

[0032] In the present invention, one end of the three adjusting support columns 200 is connected with the guide rail fixing plate 120 through a hinge shaft 222, and the other end is connected with the wall fixing plate 130 through a spherical hinge structure 131, which can improve the support stability of the adjusting support column 200. At the same time, the inclination angle of the guide rail fixing plate 120 can be adjusted by adjusting the length of each adjusting support column 200, and then the inclination angle of the elevator guide rail 110 can be adjusted. In this embodiment, according to the number of the adjusting support columns 200, both the guide rail fixing plate 120 and the wall fixing plate 130 are equilateral triangle plates. The two ends of the three adjusting support columns 200 are respectively connected to the three vertex positions of the equilateral triangle plate, and the axes of the hinge shafts 222 at one end of the three adjusting support columns 200 are also arranged in an equilateral triangle.

[0033] In the present invention, the positions of the buffer seat 224, the first buffer pad 244 and the second buffer pad 245 in the support cylinder 210 are adjustable. In this embodiment, an inner cylinder 240 is provided in the support cylinder 210. The first buffer pad 244, the buffer seat 224 and the second buffer pad 245 are arranged in the inner cylinder 240. The first buffer pad 244, the buffer seat 224 and the second buffer pad 245 are arranged in the support cylinder 210 through the inner cylinder 240. By adjusting the position of the inner cylinder 240 in the support cylinder 210, the positions of the first buffer pad 244, the buffer seat 224 and the second buffer pad 245 in the support cylinder 210 are further adjusted. In this embodiment, a threaded hole 215 is provided in the support cylinder 210. An external thread is provided on the outer periphery of the inner cylinder 240. The inner cylinder 240 is screwed into the support cylinder 210 through the thread. By screwing the inner cylinder 240, the first buffer pad 244, the buffer seat 224 and the second buffer pad 245 can be driven to move in the support cylinder 210 to adjust the positions of the buffer seat 224, the first buffer pad 244 and the second buffer pad 245 in the support cylinder 210.

[0034] In this embodiment, one end of the inner cylinder 240 has a baffle 243. A perforation for the support rod 220 to pass through is provided on the baffle 243. A push bolt 230 is threadedly connected to the other end of the inner cylinder 240. The first buffer pad 244 is an annular buffer ring. The first buffer pad 244 is located in the inner cylinder 240 and sleeved on the support rod 220. The second buffer pad 245 is a solid block. After the push bolt 230 is tightened, the second buffer pad 245, the buffer seat 224 and the first buffer pad 244 are squeezed between the baffle 243 and the push bolt 230. By screwing the push bolt 230, the position of the push bolt 230 in the inner cylinder 240 can be adjusted, and further the pre-tightening force of the push bolt 230 on the first buffer pad 244 and the second buffer pad 245 can be adjusted.

[0035] In this embodiment, the support cylinder 210 includes an outer cylinder 214 and a support frame 211 fixed to one end of the outer cylinder 214. A through hole for the support rod 220 to pass through is formed at one end of the outer cylinder 214. The inner cylinder 240 is threadedly connected to the other end of the outer cylinder 214. One end of the inner cylinder 240 away from the support rod 220 extends outside the outer cylinder 214. The push bolt 230 is connected to the end of the inner cylinder 240 extending outside the outer cylinder 214, and one end of the push bolt 230 extends outside the inner cylinder 240. One end of the push bolt 230 extending outside the inner cylinder 240 has a tightening head 232. Wrench surfaces are provided on both the tightening head 232 and the end of the inner cylinder 240 extending outside the outer cylinder 214. By using a wrench to cooperate with the wrench surfaces, the inner cylinder 240 and the push bolt 230 can be respectively screwed to rotate. The support frame 211 is used to avoid the inner cylinder 240 and the push bolt 230 and provide an operating space for the wrench. One end of the support frame 211 away from the outer cylinder 214 is connected to a connecting rod 212. The spherical hinge structure 131 includes a hinge ball and a ball hinge seat. The hinge head is fixed to the end of the connecting rod 212 away from the support frame 211, and the ball hinge seat is fixed to the wall fixing plate 130.

[0036] In this embodiment, the support rod 220 is formed by coaxially connecting a first rod 221 and a second rod 223. Specifically, threaded posts and threaded inner holes are respectively provided at opposite ends of the first rod 221 and the second rod 223, and the first rod 221 and the second rod 223 are assembled together through the threaded posts and the threaded inner holes. One end of the first rod 221 is connected to the guide rail fixing plate 120 through the hinge shaft 222, and one end of the second rod 223 is fixedly connected to the buffer seat 224. Anti-rotation keys are respectively provided on the outer circumferences of the first rod 221 and the second rod 223, and anti-rotation grooves are formed on the inner wall of the through hole of the outer cylinder 214. The anti-rotation keys and the anti-rotation grooves cooperate to prevent the support rod 220 from rotating.

[0037] In this embodiment, the support frame 211 includes two long strip-shaped connecting plates and two connecting columns 213 connected between the two connecting plates. The two connecting columns 213 are arranged in parallel at intervals, and the two connecting columns 213 are respectively located on the opposite sides of the pushing bolt 230. One of the two connecting plates is a fixed plate 233, and the other is a movable plate 234. The fixed plate 233 is fixedly connected to one end of the outer cylinder 214. One ends of the two connecting columns 213 are respectively fixedly connected to the fixed plate 233, and the other ends of the two connecting columns 213 are respectively detachably connected to the movable plate 234 through fastening bolts. The connecting rod 212 is fixedly connected to the movable plate 234. During assembly, first remove the movable plate 234 of the support frame 211 from the connecting column 213, then insert the inner cylinder 240 into the outer cylinder 214. After adjusting the position of the inner cylinder 240 in the outer cylinder 214, insert the second rod 223 together with the first buffer pad 244 and the buffer seat 224 into the inner cylinder 240, then insert the second buffer pad 245 into the inner cylinder 240, and then screw the pushing bolt 230 into the outer cylinder 214 so that the first buffer pad 244, the buffer seat 224 and the second buffer pad 245 are squeezed between the baffle 243 and the pushing bolt 230. After adjusting the pre-tightening force of the first buffer pad 244 and the second buffer pad 245, connect the movable plate 234 to the connecting column 213 through the fastening bolt.

[0038] In this embodiment, an annular protrusion 242 coaxial with the inner cylinder 240 is provided on the inner wall of the inner cylinder 240. The annular protrusion 242 is used for squeezing and cooperating with the outer peripheral wall of the second buffer pad 245. Since the second buffer pad 245 is a solid block, under the radial squeezing action of the annular protrusion 242 on the second buffer pad 245, on the one hand, the sealing performance between the second buffer pad 245 and the inner cylinder 240 can be improved. On the other hand, the second buffer pad 245 is radially squeezed by the annular protrusion 242, which can improve the flatness of the axial end faces of the second buffer pad 245, and further make the second buffer pad 245 fit tightly with the buffer seat 224 and the pushing bolt 230. In addition, a locking hole 241 is opened on the side wall of the end of the inner cylinder 240 extending out of the outer cylinder 214, and the pushing bolt 230 is limited by screwing a locking screw into the locking hole 241.

[0039] When assembling a lift guide rail bracket with vibration isolation function according to the present invention, first separate the first rod 221 and the second rod 223 of the support rod 220, remove the movable plate 234 of the support frame 211 from the connecting column 213, then insert the inner cylinder 240 into the outer cylinder 214. After adjusting the position of the inner cylinder 240 in the outer cylinder 214, insert the second rod 223 together with the first buffer pad 244 and the buffer seat 224 into the inner cylinder 240, then insert the second buffer pad 245 into the inner cylinder 240, and then screw the push bolt 230 into the outer cylinder 214 so that the first buffer pad 244, the buffer seat 224 and the second buffer pad 245 are squeezed between the baffle 243 and the push bolt 230. After adjusting the pre-tightening forces of the first buffer pad 244 and the second buffer pad 245, connect the movable plate 234 to the connecting column 213 through the fastening bolt, and then connect the second rod 223 to the first rod 221. Finally, connect one end of the support rod 220 to the hinge seat 121 on the guide rail fixing plate 120 through the hinge shaft 222, and then connect one end of the connecting rod 212 to the wall fixing plate 130 through the spherical hinge structure 131.

[0040] When using a lift guide rail bracket with vibration isolation function according to the present invention, fix the guide rail fixing plate 120 to the lift guide rail 110 through the connecting bolt 111, and fix the wall fixing plate 130 to the wall of the building through the expansion bolt 132. During use, by screwing the inner cylinder 240, the length of each adjusting support column 200 can be adjusted to adjust the inclination angle of the guide rail fixing plate 120, and thus the inclination angle of the lift guide rail 110. In addition, by screwing the push bolt 230, the pre-tightening forces of the first buffer pad 244 and the second buffer pad 245 can be adjusted. When the lift moves along the lift guide rail 110, the extrusion force and pulling force generated by the lift on the lift guide rail 110 will be absorbed by the first buffer pad 244 and the second buffer pad 245 to achieve the effects of vibration reduction and noise reduction.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
