Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically a mounting bracket for elevator guide rails. Background Technology

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates, and are divided into car guide rails and counterweight guide rails.

[0003] Currently, the installation method for existing elevator guide rails involves pre-embedding steel plates, direct burial, and pre-embedding anchor bolts. The elevator guide rail bracket is then fixed in the elevator shaft using these anchor bolts, and the elevator guide rail is subsequently installed onto the bracket using bolts. This bolt-installation method is prone to loosening when the elevator guide rail is subjected to vibration, posing a safety hazard. Furthermore, tightening multiple bolts during installation is laborious. Therefore, this application proposes a mounting bracket for elevator guide rails. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a mounting bracket for elevator guide rails, comprising:

[0029] The bracket body 100 has mounting plates 200 fixed at both ends. The surface of the mounting plates 200 has mounting holes corresponding to the anchor bolts pre-embedded in the inner wall of the elevator shaft.

[0030] The positioning component 300 is used to fix the elevator guide rail body 400 to the surface of the bracket body 100. The positioning component 300 includes two symmetrical plug-in blocks 301 fixed on the back of the elevator guide rail body 400, and plug-in slots 302 opened on the surface of the bracket body 100 and corresponding to the plug-in blocks 301. The bracket body 100 has a U-shaped cavity 303 and a driving cavity 304 respectively. Two symmetrical sliding plates 305 are slidably arranged on the inner wall of the U-shaped cavity 303, and positioning blocks 306 are fixed on the opposite sides of the two sliding plates 305. Rectangular holes extending into the two plug-in slots 302 are opened on the inner walls of both sides of the U-shaped cavity 303, and the positioning blocks 306 are slidably connected to the inner walls of the rectangular holes. The surface of the plug-in block 301 has a positioning slot 307 adapted to the positioning block 306. The positioning component 300 also includes a rotating disk 308 disposed on the front of the bracket body 100 for driving the two sliding plates 305 to move simultaneously towards the center.

[0031] See Figure 3 , Figure 5 The inner wall of the U-shaped cavity 303 is rotatably provided with a bidirectional lead screw 309, and the surfaces of the two sliding plates 305 are provided with threaded holes that are threaded to the outer surface of the bidirectional lead screw 309.

[0032] Specifically, by setting a bidirectional lead screw 309, the rotation of the bidirectional lead screw 309 can drive the two sliding plates 305 to move towards the middle simultaneously.

[0033] See Figure 3 , Figure 4 The front of the bracket body 100 is rotatably provided with a rotating shaft 3010 extending into the drive cavity 304, and a rotating disk 308 is fixed at the top of the rotating shaft 3010. A crank handle is rotatably provided on the surface of the rotating disk 308.

[0034] Specifically, by setting the rotating shaft 3010, the rotating disk 308 can drive the rotating shaft 3010 to rotate.

[0035] See Figure 3 , Figure 4 One end of the bidirectional lead screw 309 extends into the interior of the drive cavity 304, and the bottom end of the rotating shaft 3010 and the surface of the bidirectional lead screw 309 are both fixed with a first bevel gear 3011 that meshes with each other.

[0036] Specifically, by setting the first bevel gear 3011, the rotation of the rotating shaft 3010 can drive the bidirectional lead screw 309 to rotate.

[0037] In this invention, by setting a positioning component 300, the mounting bracket can insert the elevator guide rail body 400 into two insertion slots 302 via two insertion blocks 301 when installing the elevator guide rail body 400. Then, by turning the crank handle to rotate the rotating disk 308, the rotation of the rotating disk 308 drives the rotating shaft 3010 to rotate. The rotation of the rotating shaft 3010 drives the bidirectional lead screw 309 to rotate under the action of two first bevel gears 3011. The rotation of the bidirectional lead screw 309 drives the two sliding plates 305 to move towards the center at the same time, thereby driving the two positioning blocks 306 to be inserted into the positioning slots 307 on the two insertion blocks 301 respectively, realizing the effective fixation of the two insertion blocks 301, and thus realizing the effective fixation of the elevator guide rail body 400 and the bracket body 100. The installation is simple and convenient, and the stability of the elevator guide rail body 400 after installation is improved.

[0038] See Figure 3 , Figure 5 The front of the support body 100 is provided with a reinforcement component 500 for reinforcing the elevator guide rail body 400. The reinforcement component 500 includes a rectangular cavity 501 opened in the inner wall of the U-shaped cavity 303, and a rectangular plate 502 slidably disposed in the inner wall of the rectangular cavity 501. Limiting blocks 503 are fixed on both sides of the rectangular plate 502, and limiting grooves that are slidably connected to the outer surface of the limiting blocks 503 are opened on both sides of the inner wall of the rectangular cavity 501.

[0039] Specifically, by setting up the reinforcement component 500, the elevator guide rail body 400 after positioning can be effectively reinforced.

[0040] See Figure 3 , Figure 5 Two symmetrical reinforcing blocks 504 are fixed on the surface of the rectangular plate 502. The inner wall of the rectangular cavity 501 has through holes that extend to the front of the bracket body 100 and are slidably connected to the outer surface of the reinforcing blocks 504. The surface of the elevator guide rail body 400 has reinforcing holes 505 that are adapted to the reinforcing blocks 504.

[0041] Specifically, the movement of the rectangular plate 502 can drive the reinforcing block 504 to move upward and insert it into the reinforcing hole 505 to effectively reinforce the elevator guide rail body 400.

[0042] See Figure 3 , Figure 5 A threaded post 506 is rotatably provided on the top wall of the rectangular cavity 501, and a threaded hole is provided on the surface of the rectangular plate 502 to be threadedly connected to the outer surface of the threaded post 506. The bottom end of the threaded post 506 and the surface of the bidirectional lead screw 309 are both fixed with a second bevel gear 507 that meshes with each other.

[0043] Specifically, by setting the second bevel gear 507, the threaded column 506 can be automatically rotated during the rotation of the bidirectional lead screw 309.

[0044] In this invention, by setting up a reinforcement component 500, during the rotation of the bidirectional lead screw 309, the threaded column 506 can be driven to rotate under the action of the two second bevel gears 507. The rotation of the threaded column 506 causes the rectangular plate 502 to move upward, thereby causing the two reinforcement blocks 504 to move upward and insert into the two reinforcement holes 505 on the elevator guide rail body 400, thereby effectively reinforcing the elevator guide rail body 400 and further improving the stability of the elevator guide rail body 400 after installation.

[0045] Working principle: When installing the elevator guide rail body 400, the mounting bracket can insert the elevator guide rail body 400 into the two insertion slots 302 via two insertion blocks 301. Then, by turning the crank, the rotating disk 308 is rotated, which drives the rotating shaft 3010 to rotate. The rotation of the rotating shaft 3010, under the action of the two first bevel gears 3011, drives the double-acting screw 309 to rotate. The rotation of the double-acting screw 309 drives the two sliding plates 305 to move towards the center simultaneously, thereby causing the two positioning blocks 306 to be inserted into the positioning slots 307 on the two insertion blocks 301 respectively, realizing the positioning of the two insertion blocks 301. Effective fixation is achieved, thereby effectively fixing the elevator guide rail body 400 to the bracket body 100. The installation is simple and convenient, improving the stability of the elevator guide rail body 400 after installation. At the same time, during the rotation of the bidirectional lead screw 309, the threaded column 506 can be driven to rotate under the action of the two second bevel gears 507. The rotation of the threaded column 506 drives the rectangular plate 502 to move upward, thereby driving the two reinforcing blocks 504 to move upward and insert into the two reinforcing holes 505 on the elevator guide rail body 400, achieving effective reinforcement of the elevator guide rail body 400, and further improving the stability of the elevator guide rail body 400 after installation.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
