Description

Technical Field

[0001] The utility model relates to the technical field of guide rail rust removal equipment, in particular to a rust removal device for elevator guide rail maintenance. Background Art

[0002] Rust removal of elevator guide rails is an important part of elevator maintenance. As a key component of elevator operation, the surface of the guide rail must be kept smooth and clean to ensure the smooth and safe operation of the elevator. However, due to factors such as environmental humidity, dust and metal oxidation, the surface of the guide rail is prone to rust, which not only affects the operating efficiency of the elevator, but also may bring safety hazards;

[0003] Therefore, when performing maintenance on the elevator, it is necessary to remove rust from the elevator guide rails. During the rust removal, manual rust removal or a rust removal device installed on the elevator car is used to remove rust from the guide rails. For example, the Chinese utility model patent disclosed in the publication number CN219131863U: A rust removal device for elevator guide rail maintenance, the application facilitates the installation of the rust removal device at the bottom of the elevator car through a mounting block, facilitates pushing the pressure rod through a through hole, and operates the two rust removal blocks to squeeze the two sides of the guide rail through the pressure rod, and facilitates the rust removal blocks to fit tightly against the side walls of the guide rail through the notch. When the elevator is ascending or descending When the rust removal block is in motion, it drives the rust removal block to rub against the side wall of the elevator guide rail, which is convenient for rust removal of the elevator guide rail. However, when using this application, it is also necessary to manually install the application on the car for use. After the rust removal is completed, it is necessary to manually remove it to prevent the rust removal block from continuing to rub against the guide rail in the later stage and causing wear of the guide rail. Therefore, it is impossible to achieve regular and automatic rust removal operations. In addition, when the rust removal block in this application directly contacts the guide rail for rust removal operations, it is difficult to ensure uniform force on the surface of the guide rail when the rust removal block moves radially, which may lead to inconsistent surface quality after grinding and local over-grinding or under-grinding.

[0026] like Figure 1-Figure 4 As shown, two guide seats 10 are fixedly installed on the side plate 2 near the connecting plate 4, and a connecting block 11 is inserted and installed between the four guide seats 10 on the opposite side of the two side plates 2, and two wedge blocks 12 are fixedly installed on one side of the connecting block 11. The connecting block 11 located between the two wedge blocks 12 is provided with a screw hole 13. The connecting block 11 is inserted and installed between the two side plates 2 with the help of the four guide seats 10, and two wedge blocks 12 are arranged on one side of the connecting block 11, which can provide conditions for the relative movement of the two clamping plates 3. A stud 14 is fixedly installed on the output end of the motor 5, and one end of the stud 14 passes through the through hole in the connecting plate 4 and is threaded in the screw hole 13. The connecting block 11 is inserted and installed between the four guide seats 10 to limit the axial movement of the connecting block 11, so that the stud 14 rotates in the screw hole 13 and the connecting block 11 drives the two wedge blocks 12 to move horizontally.

[0027] like Figure 2-Figure 5 As shown, a C-shaped seat 15 is fixedly installed on the opposite side of the two clamps 3, and a spring seat 16 is fixedly installed above and below the C-shaped seat 15. A compression spring 17 is inserted and connected between the two spring seats 16 at the same level. An axle seat 7 is fixedly installed on the side of the clamp 3 away from the C-shaped seat 15, and a rotating shaft 18 is fixedly installed at the center position of one side of the mounting wheel 8. A plurality of countersunk holes 19 are also opened on one side of the mounting wheel 8 with the rotating shaft 18 as the center. Fixing screws 20 are inserted and installed in the countersunk holes 19, and the rotating shaft 18 is rotatably installed on the axle seat 7, a plurality of plug shafts 21 are fixedly installed on one side of the rust removal plate 9, and a screw groove 22 is opened in the plug shaft 21.

[0028] It should be noted that the utility model is a rust removal device for elevator guide rail maintenance. Before use, the base plate 1 is pre-installed on one side of the car, and a suitable bracket can be selected according to the height of the guide wheel on the car to adjust the installation height of the base plate 1, so that the contour of the installation wheel 8 on one side of the two clamps 3 is in contact with one side of the lateral part of the T-shaped guide rail. When it is necessary to remove rust from the guide rail, the motor 5 can be started by the main controller, so that the output end of the motor 5 drives the stud 14 to rotate a certain number of circles, so that the stud 14 rotates in the screw hole 13, and since the two sides of the connecting block 11 are respectively inserted between the corresponding two guide seats 10, the axial movement of the connecting block 11 is restricted, so that the connecting block 11 drives the two wedge blocks 12 to move horizontally between the four guide seats 10, so that the two wedge blocks 12 are respectively inserted into the opposite guide seats 10 using the inclined surface on one side. The two wedge blocks 12 are inserted into the corresponding C-shaped seats 15 respectively and squeeze the C-shaped seats 15 to move to one side, so that the C-shaped seat 15 drives the clamping plate 3 to move to one side. Therefore, the clamping plate 3 uses the two through holes on one side to move to one side between the two mounting shafts 6, and the compression springs 17 on the opposite side of the two mounting shafts 6 are compressed. Therefore, the other sides of the two clamping plates 3 synchronously drive the corresponding mounting wheels 8 to move toward one side of the guide rail, so that the mounting wheels 8 can drive one side of the rust removal plate 9 to contact the side of the vertical part of the guide rail. In the process of lifting the car, the outer contour of the mounting wheels 8 contacts the horizontal part of the guide rail, so that when the bottom plate 1, the side plate 2, the mounting shaft 6, the clamping plate 3, and the mounting wheels 8 drive the rust removal plate 9 to move vertically, the mounting wheels 8 also drive the rust removal plate 9 to rotate, so as to perform rust removal operation on one side of the guide rail when it rotates.

[0029] When the rust removal operation of the guide rail is completed, the motor 5 runs in the reverse direction, so that the stud 14 rotates in the reverse direction in the screw hole 13, and the connecting block 11 drives the two wedge blocks 12 to move in the reverse direction, and the wedge blocks 12 are separated from the C-shaped seat 15, and then the two clamping plates 3 are pushed to the corresponding side of the side plate 2 respectively with the help of the stretching and rebounding force of the two compression springs 17, so that the clamping plates 3 cooperate with the mounting wheels 8 to drive the rust removal plate 9 to separate from the vertical part of the guide rail.
