Description

Technical Field

[0001] The invention relates to the technical field of control cabinet detection devices, and in particular to an electrical function detection device for an elevator control cabinet. Background Art

[0002] The production inspection of elevator control cabinets requires that manufacturers must have an elevator control cabinet detection system to complete the production inspection of the control cabinet. At the same time, the traditional installation process of the elevator requires on-site elevator debugging and inspection of the elevator operation status. Once the elevator operation is abnormal, the control cabinet needs to be constantly adjusted or even replaced, which causes great inconvenience to the elevator installation. Therefore, there is an urgent need for a control cabinet detection system that can complete the test of the elevator control cabinet before the elevator is installed, simulate the elevator operation status, and complete all height work without transporting the elevator control cabinet to the site.

The elevator cabinet detection system using the utility model can realize the fast and slow car inspection of the elevator cabinet before leaving the factory, so as to prevent the functional failure of the equipment during the on-site installation and commissioning, and then spend a lot of manpower and material resources to find and eliminate the fault. At the same time, the structure of the control cabinet is also improved, the qualified rate of the equipment leaving the factory is improved, the convenience of the operator's work is increased, and the work efficiency is improved.

[0004] However, although the utility model can detect the control cabinet, for some installed control cabinets, especially those at relatively high locations, the control cabinet unit cannot be connected to the power unit of the detection device, making the detection more troublesome. Summary of the invention

[0005] The purpose of the present invention is to provide an electrical function detection device for an elevator control cabinet, which solves the problems of difficult detection, unstable structure and storage.

When the detection device rises, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the wire rack to rotate together through the rotating shaft. The wire inside the wire rack will also be released, so that longer wires can be dragged to be electrically connected to the control cabinet, making the connection more convenient. When reversing, the wires can be collected into the inside of the wire rack, making it easy to store the wires. A protective cover is provided on the outside of the wire rack to prevent the staff from being clamped and accidentally injured during operation.

[0018] 3. The present invention is provided with structures such as brackets and rollers. Since different elevator control cabinets need to be inspected, the detection device needs to be moved frequently. The detection device body is large and inconvenient to move. Therefore, rollers are provided at the bottom of the bracket to make it more convenient to move the bracket through the rollers. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-3, an electrical function detection device for an elevator control cabinet, comprising a bracket 1, a base 16 is slidably mounted inside the bracket 1, a first rack 14 is fixedly connected to one side of the base 16 by screws, a detection device 2 is mounted on the top of the base 16, a revolving door 3 is rotatably mounted on one side of the detection device 2, a handle is fixedly connected to one side of the revolving door 3 by screws, a motor 23 is mounted inside the bracket 1, an output end of the motor 23 is connected to a coaxially arranged round rod through a coupling, a first synchronous wheel 9 is fixedly connected to one side of the round rod by screws, a first spur gear 10 is fixedly connected to the other side of the first spur gear 10 by screws, a first bevel gear 8 is fixedly connected to the other side of the first spur gear 10 by screws, a second synchronous wheel 18 is rotatably mounted inside the bracket 1, a first synchronous belt 15 is sleeved on the second synchronous wheel 18 and the first synchronous wheel 9, a third synchronous wheel 28 is rotatably mounted inside the bracket 1, a second synchronous belt 19 is sleeved on the third synchronous wheel 28 and the second synchronous wheel 18, a second spur gear 26 is fixedly connected to one side of the third synchronous wheel 28 by screws, and two second racks 2 are slidably mounted inside the bracket 1. 7. The two second racks 27 are meshed and connected with the second spur gear 26. One side of the two second racks 27 is fixedly connected with the straight rod 17 by screws. One side of the two straight rods 17 is fixedly connected with the telescopic rod 20 by screws. The bottom of the telescopic rod 20 is fixedly connected with the support plate 5 by screws. The outer peripheral surface of the telescopic rod 20 is fixedly connected with the inclined block 13 by screws. The bottom of the bracket 1 is fixedly connected with two symmetrically arranged fixed blocks 21 by screws. Through the arrangement of the motor 23 and the detection device 2 and other structures, for some control cabinets with higher installation positions, the wires cannot be connected, and fault detection is more difficult. Therefore, the second spur gear 26 is driven to rotate by the output end of the motor 23, thereby driving the first rack 14 to move upward, and the base 16 also moves upward, thereby raising the detection device 2, making the detection more convenient. However, after the detection device 2 is raised, the center of gravity is easily offset to both sides, which is easy to injure the staff. Therefore, when the detection device 2 rises, the two straight rods 17 drive the telescopic rod 20 to move to both sides, thereby forming support for the entire bracket 1, making the entire structure more stable.

[0029] See also Figure 4The bracket 1 is internally rotatably installed with a rotating shaft 22, the bottom of the rotating shaft 22 is fixedly connected to a second bevel gear 24 by screws, the top of the rotating shaft 22 is fixedly connected to a wire rack 12 by screws, and a protective cover 4 is arranged outside the wire rack 12, and a clamping block 25 is arranged on the protective cover 4. Through the arrangement of structures such as the wire rack 12 and the detection device 2, when the detection device 2 rises, the first bevel gear 8 drives the second bevel gear 24 to rotate, and the second bevel gear 24 drives the wire rack 12 to rotate together through the rotating shaft 22, and the wire inside the wire rack 12 will also be released, so that a longer wire can be dragged to be electrically connected to the control cabinet, making the connection more convenient, and when reversing, the wire can be collected into the wire rack 12, so that the wires are convenient to store, and the protective cover 4 is arranged outside the wire rack 12 to prevent the staff from being clamped and injured by mistake during operation.

[0030] See also Figure 4 A through slot is provided inside the bracket 1, the motor 23 is mounted inside the through slot, and the first bevel gear 8, the first synchronous gear 9 and the first spur gear 10 are all rotatably mounted inside the through slot.

[0031] See also Figure 3 Two straight grooves are provided inside the bracket 1, and the two second racks 27 are respectively slidably connected inside the two straight grooves.

[0032] See also Figure 3 A square groove is provided inside the bracket 1, and the first rack 14 is slidably connected inside the square groove.

[0033] See also Figure 3 A slide groove is provided inside the bracket 1, and the base 16 is slidably connected inside the slide groove.

[0034] See also Figure 2 A ventilation hole 7 is provided on one side of the detection device 2, and a support rod 6 is fixedly connected to the inside of the bracket 1 by screws.

[0035] The specific implementation process of the present invention is as follows: For some control cabinets installed at higher positions, the wires cannot be connected, making fault detection more difficult. Therefore, the second spur gear 26 can be driven to rotate through the output end of the motor 23, and the second spur gear 26 drives the first rack 14 to move upward, and the base 16 also moves upward, thereby raising the detection device 2 to make the detection more convenient. However, after the detection device 2 is raised, the center of gravity shifts and easily deviates to both sides, which can easily injure the staff. Therefore, when the detection device 2 rises, the first synchronous wheel 9 also rotates together, so that the first synchronous wheel 9 drives the second synchronous wheel 18 to rotate through the first synchronous belt 15, and the second synchronous wheel 18 drives the third synchronous wheel 28 to rotate through the second synchronous belt 19, so the second spur gear 26 also rotates, and the second spur gear 26 also rotates. The wheel 26 drives the two second racks 27 to move to both sides, so that the straight rod 17 drives the telescopic rod 20 to move to both sides. When the telescopic rod 20 moves to the moving distance to both sides, the inclined block 13 will leave the limit of the fixed block 21 and pop up downward, thereby forming a support for the entire bracket 1, making the entire structure more stable. When the detection device 2 rises, the first bevel gear 8 drives the second bevel gear 24 to rotate, and the second bevel gear 24 drives the wire rack 12 to rotate together through the rotating shaft 22, and the wire inside the wire rack 12 will also be released, so that a longer wire can be dragged to be electrically connected to the control cabinet, making the connection more convenient, and when reversing, the wire can be collected into the wire rack 12, so that the wires are convenient to store. A protective cover 4 is provided on the outside of the wire rack 12 to prevent the staff from being clamped and injured by mistake during operation.

[0036] Embodiment 2:

[0037] See also Figure 4 The bottom of the bracket 1 is fixedly connected with four symmetrically arranged support rods by screws, and rollers 11 are rotatably installed inside the four support rods. The arrangement of the bracket 1 and the rollers 11 makes movement more convenient.

[0038] The specific implementation process of the present invention is as follows: Since different elevator control cabinets need to be inspected, the detection device 2 needs to be moved frequently. The detection device 2 is large and inconvenient to move. Therefore, a roller 11 is provided at the bottom of the bracket 1, so that the bracket 1 can be moved more conveniently through the roller 11.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
