Description

Technical Field

[0001] This utility model specifically relates to an adjustable counterweight side elevator guide rail bracket. Background Technology

[0002] An elevator guide rail bracket is a component used to support and fix the guide rail. It not only fixes the position of the elevator guide rail but also bears the vibration of the elevator guide rail. One end of the elevator guide rail bracket is usually fixed to the elevator shaft wall or beam, and the other end of the elevator guide rail bracket is connected to the guide rail through components such as a guide rail bracket connecting plate, thus completing the installation of the elevator guide rail bracket.

[0003] Currently, when installing elevators, the counterweight side guide rail bracket needs to be fixed inside the civil engineering shaft wall. The existing counterweight side guide rail bracket consists of expansion bolts, angle steel, and a bracket. The expansion bolts are fixed to the reserved cement ring beam in the civil engineering shaft wall, and then the angle steel is fixed in the expansion bolts with nuts, thus fastening the angle steel to the cement ring beam together. The bracket is welded to the angle steel, and finally the counterweight side guide rail is fixed to the bracket. The shortcomings are: because the installation is not adjustable, once it is welded, the position of the guide rail cannot be changed, and the strain capacity is poor. In addition, the adjustment range between the bracket and the angle steel is small. If the adjustment range is to be increased, workers need to cut the angle steel on site, which is time-consuming and labor-intensive. Moreover, the re-welding after cutting also has the problem of low assembly stability, which cannot ensure the safety of the elevator guide rail bracket in actual use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustable counterweight side elevator guide rail bracket.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An adjustable counterweight-side elevator guide rail bracket includes a counterweight guide rail fixing base, a counterweight guide rail fixing bracket fixedly installed with the counterweight guide rail fixing base, and a horizontal support beam fixedly installed with the counterweight guide rail fixing bracket.

[0007] Furthermore, the counterweight guide rail fixing base includes a base body, a first base support rib and a second base support rib formed by bending the base body inward at 90°, the first base support rib and the second base support rib abutting and welding to fix it;

[0008] Furthermore, the counterweight guide rail fixing bracket includes a bracket body that abuts against the base code body, an abutting end that is located above one end of the bracket body and is bent at 90°, and a clamping end that is located above one end of the bracket body and is fitted with the abutting end and the cross support beam.

[0009] Furthermore, the transverse support beam includes a transverse support beam body formed by bending sheet metal, and extended protrusions located at both ends of the transverse support beam body and assembled with the mounting ends.

[0010] Preferably, the base plate body has several outwardly inclined assembly holes at equal intervals.

[0011] Preferably, the bracket body is an angle steel piece, and a number of inwardly inclined assembly holes are equidistantly opened on the side that contacts the base body. A threaded assembly hole is opened at one end of the bracket body near the horizontal support beam body.

[0012] Preferably, an upper threaded assembly hole is provided at the center of the abutment end.

[0013] Preferably, the two ends of the transverse support beam body are provided with a lower mounting hole and an upper mounting hole.

[0014] Preferably, the center portion of the extended protrusion is provided with an insert groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The use of internal and external oblique mounting holes allows for precise adjustment of the counterweight guide rail fixing base and bracket positions, ensuring assembly stability. The V-shaped internal and external oblique mounting hole arrangement not only provides higher adjustment accuracy but also enhances the overall structural robustness. Furthermore, it allows for adjustment of the bracket and guide rail fixing base positions according to actual conditions, making the solution adaptable to different installation requirements and expanding its applicability. The combination of the snap-fit ​​end and the mounting groove provides a simple and effective positioning pre-assembly function, reducing the difficulty of adjustment and alignment during installation. The tightening of bolts and nuts ensures a secure connection between components.

[0017] 2. The design of the support body and the cross support beam provides additional support, making the guide rail support more stable when bearing heavy loads. At the same time, the reasonable structural design can distribute the load, improve the seismic resistance, and ensure the safety of the elevator during operation.

[0018] 3. The combination of brackets and base plates not only adapts to different installation position requirements, but also allows for easy adjustment according to site conditions, improving the system's adaptability. Therefore, through reasonable component arrangement, space occupation is reduced, while ensuring a tight fit between the brackets and guide rails, making full use of available space.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] Example

[0024] An adjustable counterweight side elevator guide rail bracket, such as Figure 1-3 As shown, it includes a counterweight guide rail fixing base 1, a counterweight guide rail fixing bracket 2 fixedly installed with the counterweight guide rail fixing base 1, and a horizontal support beam 3 fixedly installed with the counterweight guide rail fixing bracket 2.

[0025] The counterweight guide rail fixing base 1 includes a base body 11, a first base support rib 12 and a second base support rib 13 formed by bending the base body 11 inward at 90°, and the first base support rib 12 and the second base support rib 13 abut against and are welded to fix it.

[0026] Specifically, the base body 11 has several outwardly inclined mounting holes 111 at equal intervals.

[0027] The counterweight guide rail fixing bracket 2 includes a bracket body 21 that abuts against the base code body 11, an abutting end 22 that is located above one end of the bracket body 21 and is bent at 90°, and a clamping end 23 that is located above one end of the bracket body 21 and is fitted with the abutting end 22 and the cross support beam 3.

[0028] In this embodiment, the bracket body 21 is an angle steel piece, and a plurality of internally inclined mounting holes 211 are equidistantly provided on the side that contacts the base plate body 11. The bracket body 21 is provided with a threaded mounting hole 212 at one end near the horizontal support beam body 31. Specifically, the internally inclined mounting holes 211 and the externally inclined mounting holes 111 cooperate to adjust the position of the counterweight guide rail fixing base plate 1 and the counterweight guide rail fixing bracket 2 according to the actual situation, thereby improving the stability of the assembly.

[0029] It should be further explained that the inner oblique mounting holes 211 and the outer oblique mounting holes 111 are arranged in a V-shape. In actual assembly, even if the length of the transverse support beam 3 restricts the installation position of the bracket body 21, the alignment can be adjusted through the V-shaped arrangement of the inner oblique mounting holes 211 and the outer oblique mounting holes 111 to achieve a fixed installation.

[0030] The abutment end 22 has an upper threaded assembly hole 221 in the center.

[0032] The horizontal support beam body 31 has a lower through-mount hole 311 and an upper through-mount hole 312 at both ends. Specifically, after the bracket body 21 abuts against the horizontal support beam body 31, the lower through-mount hole 311 can be aligned with the lower threaded assembly hole 212. At the same time, the abutting end 22 is located inside the horizontal support beam body 31 and abuts against the horizontal support beam body 31. At this time, the upper through-mount hole 221 can be aligned with the upper through-mount hole 312 for screwing. The bracket body 21 and the horizontal support beam body 31 are then tightened by the through-mount bolt and the screw nut, so that the bracket body 21 and the horizontal support beam body 31 are fixedly installed.

[0033] An insert groove 321 is provided in the center of the extension plate 32. Specifically, when the bracket body 21 abuts against the cross support beam body 31, the snap-fit ​​end 23 will snap into the insert groove 321. Before the bolts and nuts are installed for tightening, the snap-fit ​​end 23 and the insert groove 321 can be used for positioning and pre-installation.
