Technical Field

[0001] The invention belongs to the technical field of elevators, and in particular relates to a support and adjustment device for elevator maintenance. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. Elevators are widely used in various industries and are a convenient transportation equipment.

[0003] During regular maintenance or emergency repairs of elevators, in order to ensure the safety of operators and the stability of the elevator system, the elevator car needs to be temporarily supported. The support and adjustment devices for elevator maintenance currently available on the market generally have the problem of unsatisfactory support effect. The existing support and adjustment devices often lack sufficient stability and load-bearing capacity. Since most of the existing devices are not equipped with an effective locking mechanism, it is impossible to effectively prevent the elevator from accidentally starting due to misoperation while ensuring the stability of the support, which not only increases the risk of maintenance operations, but may also pose a serious threat to the personal safety of operators. Therefore, there are deficiencies and cannot meet the use needs of maintenance personnel. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a support and adjustment device for elevator maintenance is provided, in order to achieve a more practical purpose. Summary of the invention

[0071] See also Figure 1 to Figure 2The lifting assembly 20 includes a lifting base 21 fixedly mounted on the machine base 10, a lifting frame 22 movably mounted on the lifting base 21, a lifting top plate 23 movably connected to the lifting frame 22, and a hydraulic telescopic cylinder 24 movably mounted on the lifting frame 22; the hydraulic telescopic cylinder 24 is started by external program control, the lifting frame 22 is expanded upward by the coordinated operation of the hydraulic telescopic rod and the lifting frame 22, and the lifting top plate 23 is used to drive the support assembly 30 and the elevator to move upward, thereby achieving effective support for the elevator, and this arrangement facilitates maintenance operations on the elevator.

[0072] The specific usage and function of this embodiment are as follows:

[0073] Working principle: When in use, first move the device to the designated position at the bottom of the elevator shaft and place it firmly, then start the servo motor 71 through the external control switch, use the servo motor 71 to generate kinetic energy and drive the output end to drive the driving gear 73 to rotate, the meshing transmission of the driving gear 73 and the driven gear 74 causes the rotating shaft 72 to start rotating, and the rotating shaft 72 then drives the transmission gear 75 to rotate synchronously, and the transmission rod 762 is driven to move through the meshing of the transmission gear 75 and the transmission gear 75 in the transmission rod 762, and the moving process is pushed The movable reinforcing plate 81 is gradually separated from the machine base 10, and the reinforcing plate 81 is forced to move outward until it is in close contact with the elevator shaft wall, thereby ensuring the stable installation of the machine base 10; while the reinforcing plate 81 is moving, the reinforcing rod 82 pulls the reinforcing block 83 to slide smoothly in the machine base 10. This arrangement not only enhances the stability of the reinforcing plate 81 when it moves, but also further consolidates the stability of the reinforcing plate 81 when it is in close contact with the inner wall of the elevator shaft, effectively preventing any possible shaking or displacement;

[0074] When the device is stably installed, the elevator is moved down through external control and contacts the support plate 33 on the support assembly 30. Based on the gravity of the elevator itself, the support plate 33 and the screw rod 44 connected thereto move downward. The movement of the screw rod 44 drives the movable block 43 to press down the elastic support member 42. At this time, the elastic limit assembly 45 begins to play a role. During the downward movement of the movable block 43, the limit slider 453 is pushed to slide on the limit slider 452 through the movable connecting rod 454. At the same time, the limit slider 453 moves while squeezing the limit spring 455, thereby achieving stable support for the movable block 43 and the screw rod 44, and effectively limiting the downward movement distance of the screw rod 44, effectively preventing the potential safety hazards caused by excessive downward pressure.

[0075] In addition, during the downward movement of the spiral rod 44, the screw thread and the adjusting gear 51 are used to drive the adjusting gear 51 to rotate clockwise, and the meshing transmission between the adjusting gear 51 and the adjusting rack 52 is used to make the adjusting rack 52 drive the adjusting slider 53 to move, and the adjusting slider 53 then pushes the positioning part 61 through the positioning rod 62 to automatically clamp the outer wall of the elevator; at the same time, the electromagnet block 642 on the locking plate 641 will contact the outer wall of the elevator, and the flexibility of the elastic pad 643 can be used to achieve adaptive fit with the outer wall of the elevator that may have irregular shapes on the surface, thereby enhancing the positioning effect of the elevator;

[0076] As the clamping pressure of the positioning part 61 on the outer wall of the elevator increases, the fitting assembly fits tightly on the outer wall of the elevator, and at the same time, the locking plate 641 squeezes the mounting block 634, and the linkage rod 633 pushes the sliding block 632 to slide on the fixing frame 631. The movement of the sliding block 632 further promotes the displacement of the sensing rod 6352, and then the sensing rod 6352 is used to push the movable plate 6354 and the first sensing sheet 6355 to move, so that the first sensing sheet 6355 and the second sensing sheet 6356 contact each other and send out an electrical signal, and drive the electromagnet block 642 to be energized, so that the electromagnet block 642 produces a strong magnetic locking effect on the elevator, further enhancing the stability of the elevator when supporting;

[0077] After the positioning mechanism 60 completes the positioning and locking of the elevator, the hydraulic telescopic cylinder 24 is started through external program control, and the lifting frame 22 is expanded upward by the coordinated operation of the hydraulic telescopic rod and the lifting frame 22, and the lifting top plate 23 is used to drive the support assembly 30 and the elevator to move upward, so as to achieve effective support for the elevator, and this arrangement facilitates maintenance operations on the elevator; and after the elevator maintenance operation is completed, the electromagnet block 642 is powered off through an external control switch, and the elevator is controlled to move upward and separate from the locking assembly 64, so as to complete the positioning and unlocking of the elevator, and then the servo motor 71 is controlled to reverse, and the transmission rod 762 drives the reinforcement plate 81 to separate from the elevator shaft wall, so as to achieve the resetting of the reinforcement plate 81, and finally the device is moved out of the elevator shaft.
