Technical Field
[0001] The utility model relates to the technical field of elevator maintenance, in particular to an elevator car top maintenance locking device. Background Art
[0002] For a machine-roomless elevator, since there is no dedicated elevator machine room, the main machine is generally placed in the space between the car at the top of the hoistway and the elevator hoistway wall. To ensure the safe operation of the elevator, the main machine and other equipment need to be maintained regularly. To ensure the safety of the staff, the car is generally fixed in a suitable position, and the car top is used as the maintenance platform.
[0003] At present, the elevator usually plays a role of traction and drive through the traction system. It converts electrical energy into mechanical energy through the motor and transmission device, so that the car runs smoothly along the guide rail. The traction system needs to cooperate with the control system to control the operation of the car, so that the car rises or falls smoothly along the guide rail to the specified height. When maintaining the main machine on the elevator car top, the power supply needs to be cut off to ensure that the electrical equipment is in a safe state. At the same time, a dedicated elevator maintenance door needs to be used to fix the car, but the maintenance door can only provide limited support force and cannot completely fix the car, which has certain potential safety hazards.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 to 3 , a maintenance locking device for an elevator car top in this embodiment includes a car top 1 and a mounting support plate 4 installed in an elevator shaft. A cross beam 2 is provided on the front side of the car top 1. Sliding seats 6 are provided at both ends of the cross beam 2. A slide rail 5 is provided on the side of the mounting support plate 4 close to the car top 1. The sliding seat 6 is slidably connected to the slide rail 5, and a locking assembly 8 is provided on the cross beam 2.
[0020] The locking assembly 8 includes a vertical plate 81. The vertical plate 81 is provided on the side of the cross beam 2 away from the car top 1. A threaded rod 82 is threadedly connected inside the vertical plate 81. One side of the threaded rod 82 is rotatably connected to a sliding plate 83. Oblique plates 84 are hinged at both ends of the sliding plate 83. Link rods 87 are hinged at both ends of the vertical plate 81. The side of the link rod 87 away from the vertical plate 81 is hinged to a connecting slider 88. The connecting slider 88 is slidably connected to a chute 86 opened on the side wall of the oblique plate 84. Locking columns 85 are provided on the opposite sides of the two oblique plates 84. Two locking blocks 9 are provided on the side wall of the mounting support plate 4. The slide rail 5 is located between the two locking blocks 9. A plurality of equally spaced locking grooves 91 are opened on the side of the locking block 9 away from the slide rail 5. The locking column 85 is adapted to the locking groove 91.
[0021] It should be noted that by providing the locking assembly 8 between the mounting support plate 4 and the car top 1, when maintaining the main equipment on the top of the car, it is necessary to first cut off the elevator power supply, and cooperate with the locking assembly 8 to make the locking column 85 snap into the locking groove 91 on the locking block 9, so that the car top 1 can be fixed on the mounting support plate 4, further ensuring the safety of the maintenance.
[0022] Please refer to Figure 2 , in this embodiment, a rotating block 89 is provided on the side of the threaded rod 82 away from the sliding plate 83. A plurality of circumferentially equally spaced limiting grooves 891 are opened on the side wall of the rotating block 89. A fixing plate 10 is provided on the side wall of the vertical plate 81. A limiting insertion rod 11 is inserted inside the fixing plate 10. One end of the limiting insertion rod 11 is inserted into the limiting groove 891.
[0023] By pulling the limiting insertion rod 11, it can be withdrawn from the limiting groove 891, and the setting of the limiting insertion rod 11 can limit the rotation of the rotating block 89, thereby preventing the problem of rotation caused by accidental touch and ensuring the firmness of the locking.
[0024] Among them, a guiding groove 7 is formed on the surface of the cross beam 2. A guiding block is arranged on one side of the sliding plate 83 close to the guiding groove 7, and the guiding block is slidably connected to the inside of the guiding groove 7.
[0025] Since the guiding block is slidably connected to the inside of the guiding groove 7, when the threaded rod 82 rotates, it will not drive the sliding plate 83 to rotate together. And under the limiting effect of the vertical plate 81 being threadedly connected to the threaded rod 82, the sliding plate 83 can be pushed to translate.
[0026] Please refer to Figure 1 , in this embodiment, a guardrail 3 is provided on the front side of the car top 1. The guardrail 3 is of a U-shaped structure. There is a certain distance gap between the guardrail 3 and the car top 1. Both ends of the cross beam 2 penetrate through the gap between the guardrail 3 and the car top 1 and extend to the outside.
[0027] It should be noted that by setting the guardrail 3, it has a protective effect on the maintenance personnel standing on the top of the car top 1.
[0028] The working principle of the above embodiment is as follows: When in use, first cut off the power supply of the elevator to ensure that the electrical equipment is in a safe state. Before the maintenance personnel stand on the top of the car top 1 to repair the main engine equipment, first rotate the rotating blocks 89 on both sides to drive the threaded rod 82 to rotate, which can drive the sliding plate 83 to move towards one side of the vertical plate 81, thereby pulling the two inclined plates 84 to rotate relative to each other to make the included angle between them smaller, so that the locking column 85 can be inserted into the inside of the locking groove 91 to be locked. Then insert the limit insertion rod 11 into the corresponding limit groove 891 to limit the rotating block 89 to prevent accidental rotation, and the car can be connected and fixed to the installation support plate 4, further ensuring the safety of the maintenance.
[0029] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0030] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
