Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to an elevator guide rail structure. Background Art

[0002] Elevator guide rails are one of the main structures of an elevator. They are composed of steel rails and connecting plates and are usually divided into car guide rails and counterweight guide rails. In terms of cross-sectional shape, they can be divided into three types: T-shaped, L-shaped and hollow. Among them, T-shaped guide rails are the most commonly used. They have the characteristics of strong rigidity, high reliability, safety and low cost. The guide rails are installed on the shaft wall of the elevator shaft and are fixedly connected by the guide rail frame and guide rail bracket. They provide guidance for the up and down movement of the elevator car and counterweight device, and also withstand the impact force during elevator braking and emergency braking of the safety clamp.

[0003] Because the elevator guide rails are exposed in the hoistway and lack a shielding structure, dust or other dirt easily adheres to the surface of the elevator guide rails, thereby increasing the friction between the elevator and the guide rails, causing the elevator to run unsteadily and even cause shaking or jittering. Therefore, an elevator guide rail structure is proposed to solve the above problem. Utility Model Content

The end of the slider 213 away from the rack 220 is rotatably connected to the extrusion wheel 202. Figure 4 As shown, the spring 212 pulls the slider 213 to the left, so that when the slider 213 moves to the right, the spring 212 pulls the slider 213 to return along the slide groove 211;

[0028] The T-shaped track 101 extends in the vertical direction, and a welding block 102 is welded and fixed at one end of the front of the T-shaped track 101. An extrusion block 103 is fixedly installed in the middle of the front of the welding block 102.

The extrusion block 103 and the extrusion wheel 202 are located on the same vertical straight line, and the side of the extrusion block 103 is in active contact with the extrusion wheel 202. Figure 1 As described above, when the extrusion wheel 202 moves and passes through the extrusion block 103, it is subjected to a rightward force, thereby driving the slider 213 to move rightward;

[0029] The bottom of one side of the bottom block 207 is symmetrically fixedly connected with a connecting rod 214, and the bottom ends of the two connecting rods 214 are fixedly connected with a connecting plate 215. The surface of the connecting plate 215 is provided with connecting holes on both sides. Figure 4 As shown, screws or bolts can be inserted into the connection holes to fix them to the elevator car;

The bottom end of the threaded shaft 219 is threadedly connected to the internal threaded hole 217. The dust box 218 is located below the cleaning brush 210 as a whole. Figure 4-Figure 5 As shown, the dust box 218 is fixed to the mounting frame 216 by a threaded shaft 219, thereby preventing the dust box 218 from being separated from the mounting frame 216 when the elevator car is raised or lowered;

[0031] The cleaning mechanism 2 also includes a top block 201, the bottom of the top block 201 is fixedly installed with the top of the bottom block 207, the top surface of the top block 201 is fixedly connected to three extension blocks 203, the sides of each extension block 203 are symmetrically fixedly connected to the clamping plate 204, the tops of adjacent clamping plates 204 are connected to the guide wheel 205 for common rotation, the lower ends of the outer walls of adjacent clamping plates 204 are fixedly connected to the hoop 206 by bolts, and the bolts on the surface of the hoop 206 pass through the clamping plate 204 and are threadedly connected to the extension block 203, the outer surface of the T-shaped track 101 is slidably connected to each guide wheel 205, as shown in FIG. Figure 1 As shown, the guide wheel 205 supports the cleaning mechanism 2 as a whole, thereby preventing other components in the cleaning mechanism 2 from tilting due to lack of support, and preventing the surface of the elevator guide rail 1 from being scratched.

[0032] The working principle of this utility model:

[0033] The cleaning mechanism 2 is installed as a whole above the elevator car, and is fixed to the top of the elevator car by inserting fastening screws or bolts into the connecting plate 215;

[0034] Secondly, when the elevator car is running, the cleaning brush 210 scrapes dirt along the T-shaped track 101 and removes dirt from its surface. When the car descends, the bottom side of the cleaning brush 210 pushes the dirt on the surface of the T-shaped track down into the dust box 218. When the car rises, the cleaning brush 210 collects the dirt on the top. When the squeezing wheel 202 moves up and contacts the squeezing block 103, the squeezing wheel 202 is pushed, and the slider 213 and the rack 220 move toward the gear 208. As a result, the gear 208 rotates due to the engagement with the rack 220, and the rotating rod 209 drives the cleaning brush 210 to move toward the mounting frame 216, so that the dirt accumulated on the top of the cleaning brush 210 is introduced into the dust box 218.

[0035] When the car is to be maintained, the threaded shaft 219 can be loosened, and the dust box 218 can be taken out from the mounting frame 216 and cleaned.
