Description

Technical Field

[0001] This utility model relates to the field of transportation operation technology, and in particular to a power distribution cabinet operation linkage lifting device. Background Technology

[0002] The linkage lifting platform is used for the installation of servo modules and power distribution panels inside machine tool power distribution cabinets, as well as for terminal block wiring. Currently, the problems with power distribution cabinet installation are:

[0003] (1) When installing the servo module inside the electrical cabinet, it is necessary to hold the servo module by hand and install it to the upper part of the electrical cabinet, which is quite strenuous. The servo module is expensive, and if it is dropped, it will cause great damage.

[0004] (2) Currently, the power distribution cabinets are placed on pallets. When workers are installing and wiring inside the cabinets, the height is not matched. Sometimes, because the cabinets are too high, a ladder is needed to assist in installing the servo modules. Sometimes, because the wiring position inside the cabinets is too low, workers need to bend over at a large angle to perform the work, which affects the reliability of the wiring.

[0005] Therefore, there is an urgent need for a new type of power distribution cabinet linkage lifting platform to solve the problem of height inconsistency when operators are installing servo modules and doing wiring work inside the power distribution cabinet. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to realize the synchronous lifting of two lifting platforms through gear and rack transmission. The power distribution cabinet and the operator are on different platforms. The forward and reverse rotation of the drive motor is controlled by the button on the power control box. This realizes a highly coordinated power distribution cabinet operation linkage lifting device when the operator is installing servo modules and doing wiring work inside the power distribution cabinet.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A power distribution cabinet operation linkage lifting device includes a base. The power distribution cabinet operation linkage lifting device further includes a first lifting part, a second lifting part, and a drive motor and a gear and rack transmission component located between the two. The gear and rack transmission component includes a gear and two racks located on both sides of the gear and respectively meshing with the gear. The first lifting part includes multiple vertical guide rails, multiple sliders, and a first lifting platform fixedly connected to the multiple sliders. The first lifting platform is used for the operator to stand on. The multiple vertical guide rails are fixed on the base, and each vertical guide rail is slidably connected to each slider. The first lifting platform includes a diagonal brace and a platform plate. The racks are fixedly connected to the platform plate through the diagonal brace. The drive motor drives the gear and rack transmission component to drive the first lifting part and the second lifting part to lift synchronously.

[0009] Preferably, the structure of the second lifting part is the same as that of the first lifting part.

[0010] Preferably, the second lifting part includes a second lifting platform, which is used to place the power distribution cabinet.

[0011] Preferably, the power distribution cabinet operation linkage lifting device further includes a speed reducer, and the drive motor is connected to the speed reducer in a transmission connection.

[0019] This application presents a power distribution cabinet operation linkage lifting device. The first and second lifting platforms slide up and down on vertical guide rails via fixed sliders. The operator and the power distribution cabinet are positioned on separate lifting platforms. A gear and rack transmission mechanism connects the two platforms, enabling coordinated lifting and lowering. This effectively solves the problem of height mismatch encountered during power distribution cabinet installation. By raising the height of the power distribution cabinet, wiring work at the bottom can be performed more easily; by lowering the height of the power distribution cabinet while raising the operator's height, the servo module operation at the top of the power distribution cabinet can be carried out efficiently, eliminating the need for ladders for climbing.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Figures 1-2This utility model discloses a power distribution cabinet operation linkage lifting device, comprising a base 100, a first lifting section 200, a second lifting section 300, a drive motor 400, and a gear and rack transmission component 500 located between the two. The first lifting section 200 includes multiple vertical guide rails 201, multiple sliders 202, and a first lifting platform 203 fixedly connected to the sliders 202. The first lifting platform 203 is used for the operator to stand on. The multiple vertical guide rails 201 are fixed on the base 100, and each vertical guide rail 201 is slidably connected to each slider 202. The power distribution cabinet operation linkage lifting device also includes an electrical control box 800, located in the first lifting section 200. By operating the buttons on the electrical control box 800, the drive motor 400 is controlled to rotate forward and backward. When the operator rises, the power distribution cabinet 900 descends, and when the power distribution cabinet 900 descends, the operator rises. By adjusting different working heights, the problem of height inconsistency when the operator is wiring inside the power distribution cabinet can be effectively solved.

[0027] The gear and rack transmission component 500 includes a gear 501 and two racks 502 located on both sides of the gear 501 and meshing with the gear 501 respectively. The output shaft of the reducer 600 is connected to the gear 501 by a key. Each rack 502 is bolted to a first lifting platform 203 or a second lifting platform 301 located on the same side as the gear 501.

[0028] Specifically, the first lifting platform 203 includes a first diagonal brace 2031, a second diagonal brace 2032, and a platform plate. The first diagonal brace 2031 and the second diagonal brace 2032 are symmetrically fixed on both sides of the platform plate. One side of the first diagonal brace 2031 and one side of the second diagonal brace 2032 are respectively bolted to the rack 502. The rack 502 is fixedly connected to the platform plate through the first diagonal brace 2031 and the second diagonal brace 2032. The drive motor 400 drives the gear and rack transmission component 500 to drive the first lifting part 200 and the second lifting part 300 to lift synchronously.

[0029] Specifically, the structure of the second lifting part 300 is the same as that of the first lifting part 200.

[0030] The second lifting unit 300 includes a second lifting platform 301, which is used to place the power distribution cabinet 900, so that the power distribution cabinet 900 and the operator are on different platforms.

[0031] The power distribution cabinet operation linkage lifting device also includes a reducer 600, and the drive motor 400 is connected to the reducer 600 for transmission.

[0032] Specifically, the reducer 600 is equipped with a brake seat. In case of an emergency during the operation of the lifting platform, such as a failure of the drive motor 400, a malfunction of the control system, or operator error, the brake seat can immediately come into play and quickly stop the lifting movement of the platform, preventing the platform from accidentally falling or rising too high and causing a safety accident, thus providing reliable safety protection for operators and equipment.

[0033] The power distribution cabinet operation linkage lifting device also includes a mounting plate 700, which is fixed between the first lifting platform 203 and the second lifting platform 301.

[0034] Mounting plate 700 has mounting holes. Drive motor 400 and reducer 600 pass through the mounting holes and are fixed to the outside of mounting plate 700. Gear 501 is fixed to the inside of mounting plate 700. The structural layout is more reasonable and the operating environment of gear and rack transmission component 500 is safer.

[0035] The power distribution cabinet operation linkage lifting device also includes a travel limit switch (not shown in the figure), which is located on the first lifting platform 203 and the second lifting platform 301, corresponding to the upper and lower limit positions.

[0036] In other embodiments of this application, travel limit switches are installed at both ends of the vertical guide rail 201 to limit the upper and lower limit positions of the first lifting platform 203 and the second lifting platform 301. When the first lifting platform 203 and the second lifting platform 301 rise or fall to the set 600mm travel end point, the corresponding travel limit switch is triggered to stop the drive motor 400 from moving and prevent the platform from exceeding the travel range and causing damage. The travel limit switches are installed at both ends of the rack 502, similar to those installed at both ends of the vertical guide rail 201. When the gear 501 moves the rack 502 to the set travel boundary, the rack 502 touches the travel limit switch, thereby controlling the drive motor 400 to stop, so as to accurately control the travel of the lifting platform.

[0037] In a preferred embodiment of this application, the vertical travel of the first lifting platform 203 and the second lifting platform 301 is 600mm.

[0038] In use, the power distribution cabinet operation linkage lifting device of this application allows the first lifting platform 203 and the second lifting platform 301 to slide up and down on the vertical guide rail 201 via fixed sliders 202. The operator and the power distribution cabinet 900 are located on different lifting platforms. A gear and rack transmission component 500 is installed between the two lifting platforms to achieve linkage lifting between the two platforms. The operator operates the device by pressing the button on the electrical control box 800 located on the first lifting platform 203 to control the forward and reverse rotation of the drive motor 400. At the same time, the torque output is achieved through the reduction ratio of the reducer 600. The rotation of the gear 501 drives the rack 502 to move up and down, so that when the operator rises, the power distribution cabinet 900 falls, and when the power distribution cabinet 900 falls, the operator rises. This application's power distribution cabinet operation linkage lifting device uses a first lifting platform 203 and a second lifting platform 301, which slide up and down on a vertical guide rail 201 via fixed sliders 202. The operator and the power distribution cabinet 900 are located on different lifting platforms. A gear and rack transmission component 500 is installed between the two lifting platforms to achieve linkage lifting of the two platforms. This effectively solves the problem of height mismatch encountered during the installation of the power distribution cabinet 900. By raising the height of the power distribution cabinet 900, wiring work at the bottom can be carried out more easily; by lowering the height of the power distribution cabinet 900 and raising the height of the operator, the servo module operation at the top of the power distribution cabinet 900 can be carried out efficiently without the need for a ladder to climb. By adjusting different working heights, the problem of height inconsistency when the operator is wiring inside the power distribution cabinet 900 can be effectively solved.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
