Description

Elevator car top operation inspection equipment

Technical Field

The utility model relates to the technical field of elevator car top maintenance, in particular to an elevator car top operation maintenance device.

Background Art

An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin. It is used to carry people or goods in multi-story buildings. The elevator is generally inspected by fixing the cabin in a suitable position and using the cabin roof as a maintenance platform. In the existing maintenance method, there are no corresponding protective measures for maintenance personnel when they are inspecting on the cabin roof. When maintenance personnel carry tools and equipment for maintenance, it is easy for equipment to slip, tools to fall and be lost, or even maintenance personnel to lose balance and step on empty air, which may cause safety hazards.

The Chinese patent authorization announcement number: CN217201487U provides an elevator car top maintenance safety protection device. The scheme uses the mesh, the connecting magnet and the protective magnet to cooperate with each other, so that when the maintenance is carried out on the car top, the maintenance equipment and tools can be adsorbed on the protective magnet to prevent them from sliding or rolling, thereby ensuring the safety of the equipment and tools. Through the setting of the clamping fixing component, the four support rods can be inserted into the four through holes correspondingly, and the plate rotation degree is rotated, so that the rotating plate drives the rotating rod and the card block to rotate, so that the card block and the triangular card block are mutually clamped to prevent the support rod from being separated from the through hole, thereby ensuring the stability of the protection frame. When the maintenance personnel are unbalanced, they can grasp the protection frame for balance adjustment. At the same time, the connection method is simple, and the maintenance personnel can quickly install and disassemble it, thereby ensuring the safety of the maintenance personnel and improving the work efficiency. However, the height of the entire protection cannot be adjusted, and the staff cannot be fully protected when standing. If the guardrail is made too high, it will greatly affect the operation of the elevator.

Therefore, it is necessary to provide an elevator car top operation maintenance equipment to solve the above technical problems.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Referring to FIGS. 1 to 4 , an elevator car top operation inspection device provided in an embodiment of the utility model includes an adjustment component 1, a first guardrail component 2 and a second guardrail component 3 are provided in the middle of the adjustment component 1, and the first guardrail component 2 and the second guardrail component 3 are arranged diagonally;

The adjustment assembly 1 includes a mounting base 101 , the upper end of the mounting base 101 is fixedly connected to a rack 102 , the upper end of the rack 102 is fixedly connected to a limit block 103 , and the middle of the rack 102 is slidably connected to a sliding sleeve 104 .

The sliding sleeve 104 is internally rotatably connected to a rotating shaft 105, a gear 106 is fixedly connected to the middle of the rotating shaft 105, and the rotating shaft 105 and the rack 102 are meshed with each other, a worm wheel 107 is also fixedly connected to the middle of the rotating shaft 105, a worm 108 is internally rotatably connected to the sliding sleeve 104, and the worm 108 and the worm wheel 107 are meshed with each other, and one end of the worm 108 and located on the outside of the sliding sleeve 104 is fixedly connected to a rotating handle 109.

The first guardrail assembly 2 includes a first railing 201 fixedly connected to the middle of the sliding sleeve 104 , a plurality of hooks 202 are fixedly connected to the middle of the first railing 201 , and a plurality of hanging sleeves 203 are also fixedly connected to the middle of the first railing 201 .

The second guardrail assembly 3 includes a second railing 301 fixedly connected to the middle of the sliding sleeve 104, and a placement plate 302 is slidably connected to the middle of the second railing 301 via a sliding rail.

The sliding sleeve 104 has a strip-shaped sliding groove inside to cooperate with the rack 102 for sliding and limiting.

A semicircular groove is formed at the upper end of the placement plate 302;

The provision of the semicircular groove can prevent workers from accidentally slipping when sitting on the upper end, and can also prevent the upper end of the tool from slipping.

When working, it is necessary to first install a pair of adjustment components 1 on the top of the car through the mounting base 101. The mounting base 101 can be connected to the top of the car through bolts. After installation, when the staff needs to inspect the top of the car, they can first turn the rotating handle 109. The rotating handle 109 drives the worm 108 fixedly connected thereto to rotate. The rotation of the worm 108 drives the worm gear 107 meshing with it to rotate. The rotation of the worm gear 107 drives the rotating shaft 105 fixedly connected to the middle part to rotate. The rotation of the rotating shaft 105 drives the gear 106 fixedly connected to the middle part to rotate. Because the gear 106 and the rack 10 2 meshes, so when the gear 106 rotates, it can drive the sliding sleeve 104 to slide in the middle of the rack 102, thereby driving the first railing 201 and the second railing 301 fixedly connected to the middle to move up and down, so as to adjust the height according to the actual maintenance situation, and can also be adjusted according to the height of the staff to prevent accidental falls. At the same time, the staff can hang the maintenance tools through the arrangement of multiple hooks 202 and hanging sleeves 203 to prevent the tools from falling and causing unnecessary trouble. If the maintenance is tired, they can also sit on the upper end of the placement plate 302 for a short rest to prevent accidents caused by excessive fatigue.
