Description

Technical Field

[0001] This invention relates to a control cabinet testing auxiliary device, and more particularly to an elevator control cabinet testing auxiliary device. Background Technology

[0002] An elevator control cabinet is an electrical control device that houses various electronic components and electrical parts within a protective cabinet structure. It's used to control elevator operation and is typically located in the elevator machine room. In elevators without a machine room, the control cabinet is placed near the landing doors on the ground or top floor. Because the elevator control cabinet is the control hub for elevator operation, a malfunction in it can affect elevator safety. Therefore, before leaving the factory, the elevator control cabinet undergoes a full-elevator performance simulation test. During placement and transportation, the elevator control cabinet is generally placed vertically. During testing, workers need to perform wiring tests at different heights within the control cabinet, making it difficult to conduct the tests in a comfortable position, which can easily lead to muscle soreness.

[0003] For example, patent application number 201721591102.0 discloses a power distribution cabinet transfer trolley. In use, the trolley is first moved to the location of the power distribution cabinet. After the trolley is raised to a certain angle using a hydraulic system, the power distribution cabinet is tilted slightly. Then, a support is inserted into the bottom of the cabinet so that the side guards are flush with the cabinet surface. Next, the hydraulic system is adjusted to lower the overall angle of the trolley and cabinet, causing the support to lift the bottom of the cabinet and tilt it downwards. Once the casters contact the ground, the cabinet is fully loaded onto the upper part of the side guards. This patent can change the angle of the control cabinet, placing it at a convenient angle for testing by staff, improving their comfort. It also makes loading the cabinet easier. However, loading the cabinet usually requires two people: one to push the elevator control cabinet to tilt, and the other to insert the trolley support under the control cabinet and load it onto the trolley. This results in high labor costs, and the staff controlling the tilt of the elevator control cabinet experience significant physical exertion and a risk of injury. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for testing elevator control cabinets. It enables automated handling of elevator control cabinets, reducing the labor intensity of workers.

[0005] The technical solution of the present invention: An elevator control cabinet testing auxiliary device includes a base, a bracket on the rear side of the base, guide rails on the left and right sides inside the bracket, a sliding seat on the guide rails via guide shoes, a hydraulic rod for driving the sliding seat to move on the upper part of the bracket, and a frame connected to the outer sides of the bracket via climbing blocks; a support plate on the lower front side of the sliding seat via a first hinge seat, a top plate on the upper front side of the sliding seat via a second hinge seat, a first rotating shaft corresponding to the support plate on the lower side of the base, a second rotating shaft corresponding to the top plate on the upper side of the base, wheels at the bottom of the bracket, and a handle at the upper rear side of the bracket. When the elevator control cabinet needs to be moved, this application is moved to the front of the elevator control cabinet, and the hydraulic rod is activated to make the sliding seat move downward. During the downward movement of the sliding seat, the top plate is in a horizontal state. At this time, the top plate is in its longest state in the horizontal direction, which allows the elevator control cabinet to tilt. At the same time, the support plate is in a state of tilting downward towards the elevator control cabinet. During the process of pushing towards the elevator control cabinet, the angle of the top plate changes, so that the elevator control cabinet gradually returns to its original position, and the support plate can be extended into the bottom of the elevator control cabinet. The final state is that the support plate and the top plate are tilted upward towards the elevator control cabinet, and the elevator control cabinet is located between the support plate and the top plate, realizing the automatic handling of the elevator control cabinet.

[0006] In the aforementioned elevator control cabinet testing auxiliary device, a fixed plate is provided in the middle of the outer side of the bracket, and a rotatable support leg is provided in the fixed plate. A clamp corresponding to the support leg is also provided on the outer side of the bracket.

[0007] In the aforementioned elevator control cabinet testing auxiliary device, the fixed plate includes a housing, a horizontal mounting shaft in the middle of the housing, and two positioning holes at the edge of the housing, with a locking block provided in the positioning hole via a spring.

[0008] In the aforementioned elevator control cabinet testing auxiliary device, the upper end of the support leg is provided with a mounting hole corresponding to the mounting shaft, one side of the mounting hole is provided with a rotating wheel corresponding to the locking block, and the lower side of the support leg is provided with a caster.

[0009] In the aforementioned elevator control cabinet testing auxiliary device, the handle is provided with a toggle block, and the toggle block is provided with a connecting rope connected to the locking block.

[0010] In the aforementioned elevator control cabinet testing auxiliary device, guide bars are provided on both sides of the frame, a lead screw is provided in the frame to drive the support to move up and down, a lead screw seat connected to the climbing block is provided on the lead screw, and a motor for driving the lead screw is provided on the upper side of the frame.

[0011] In the aforementioned elevator control cabinet testing auxiliary device, a first guide groove corresponding to a first rotating shaft is provided in the tray, and a contact switch is provided on the upper surface of the tray.

[0012] In the aforementioned elevator control cabinet testing auxiliary device, a second guide groove corresponding to the second rotating shaft is provided in the top plate.

[0013] In the aforementioned elevator control cabinet testing auxiliary device, the distance between the first rotating shaft and the sliding seat is less than the distance between the second rotating shaft and the sliding seat.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application guides the movement of the sliding seat by setting guide rails and sliding seats with guide shoes. The hydraulic rod can drive the sliding seat to move up and down. During the downward movement of the sliding seat, it will drive the top plate and the support plate to move. First, the top plate will push the elevator control cabinet, causing the elevator control cabinet to tilt. Then the support plate can move to the bottom of the elevator control cabinet. During the movement, the angle of the top plate changes, causing the elevator control cabinet to gradually return to its original position. During the return process, the support plate has moved to the bottom of the elevator control cabinet and the angle of the support plate is tilted upward, making the fixation more reliable and preventing tipping. During the loading of the elevator control cabinet, there is no need for the staff to tilt the elevator control cabinet, which improves safety and reduces the labor intensity of the staff.

[0016] 2. This application uses a toggle block to drive the connecting rope to move, thereby allowing the locking block to move along the positioning hole. As a result, the locking block cannot lock the wheel, allowing the support leg to rotate and support the base. When the elevator is laid down, the support leg can also rotate continuously, causing the elevator control cabinet to tilt continuously until it is in a horizontal position. This not only ensures good safety but also allows the staff to perform circuit tests on the elevator control cabinet in a more comfortable position.

[0017] 3. This application uses a motor to drive a lead screw to rotate, so that the bracket can move along the guide bar via the climbing block, thereby adapting to elevator control cabinet placement racks of different heights. A contact switch is set on the upper surface of the pallet, so that when the pallet moves to the lower surface of the placement rack, the contact switch is triggered, causing the motor to stop moving. This allows the packaged elevator control cabinet to be moved. By adjusting the height of the pallet by the motor, it can be adapted to placement racks of different heights, making it more versatile and simple to operate. Attached Figure Description

Detailed Implementation

[0027] Example 1. An auxiliary device for testing an elevator control cabinet, configured as follows: Figure 1-8 As shown, the system includes a base 1, a support 2 on the rear side of the base 1, guide rails 3 on the left and right sides inside the support 2, a sliding seat 5 on the guide rails 3 via guide shoes 4, a hydraulic rod 14 on the upper part of the support 2 to drive the sliding seat 5 to move, and a frame 39 connected to the outer sides of the support 2 via climbing blocks 38; a support plate 6 on the lower front side of the sliding seat 5 via a first hinge seat 7, a top plate 9 on the upper front side of the sliding seat 5 via a second hinge seat 8, a first rotating shaft 10 corresponding to the support plate 6 on the lower side of the base 1, a second rotating shaft 11 corresponding to the top plate 9 on the upper side of the base 1, a wheel 28 at the bottom of the support 2, and a handle 24 at the upper rear side of the support 2.

[0028] The bracket 2 has a fixed plate 16 on the middle of its outer side, and a rotatable support leg 15 in the fixed plate 16. The bracket 2 also has a clamp 26 on its outer side that corresponds to the support leg 15.

[0029] The fixed plate 16 includes a housing 17, a horizontal mounting shaft 18 in the middle of the housing 17, and two positioning holes 19 at the edge of the housing 17. A locking block 21 is provided in the positioning hole 19 through a spring 20.

[0030] The upper end of the support leg 15 is provided with a mounting hole 22 corresponding to the mounting shaft 18, and a rotating wheel 23 corresponding to the locking block 21 is provided on one side of the mounting hole 22. The lower side of the support leg 15 is provided with a caster 29.

[0031] The grip 24 is provided with a toggle block 27, and the toggle block 27 is provided with a connecting rope 25 that is connected to the locking block 21.

[0032] The frame 39 is provided with guide strips 40 on both sides, and a lead screw 41 for driving the support 2 to move up and down is provided in the frame 39. The lead screw 41 is provided with a lead screw seat 42 connected to the climbing block 38, and a motor 44 for driving the lead screw 41 is provided on the upper side of the frame 39.

[0033] The tray 6 has a first guide groove 12 corresponding to the first rotating shaft 10, and the upper end face of the tray 6 is provided with a contact switch 43 for controlling the motor 44.

[0034] The top plate 9 is provided with a second guide groove 13 corresponding to the second rotating shaft 11.

[0035] The distance between the first rotating shaft 10 and the sliding seat 5 is less than the distance between the second rotating shaft 11 and the sliding seat 5.

[0036] Example 2. Based on Example 1, the sliding seat 5 includes an upper fixed seat 37 connecting to the top plate 9 and a lower fixed seat 31 connecting to the support plate 6. The lower fixed seat 31 has a limiting strip 32 on its upper side, and evenly distributed positioning holes 33 on one side of the limiting strip 32. The upper fixed seat 37 has a limiting groove 34 corresponding to the limiting strip 32, and a keyhole 35 corresponding to the positioning hole 33 is provided outside the limiting groove 34. The base 1 has a vertically arranged mounting hole 36. By moving the lower fixed seat 31 relative to the upper fixed seat 37, the sliding seat 5 can be matched with elevator control cabinets of different heights. After the movement is complete, the fixing block is inserted into the positioning hole 33 and the keyhole 35 to achieve locking. Simultaneously, the first rotating shaft 10 and the second rotating shaft 11 are installed in the mounting hole 36 according to the change of the sliding seat.

[0037] Example 3. Based on Example 1 or 2, the length of the support leg 15 is increased so that when the frame 39 is in a vertical position, the support leg 15 supports the bracket 2. Simultaneously, a motor to drive the wheel and a reversing rotation assembly are installed at the wheel 28, and a route recognition system is installed. The recognition system can use a reader located at the bottom of the frame and corresponding guide signals set up in the factory area. By recognizing the guide signals through the reader, the elevator control cabinet can be automatically moved, reducing labor costs.

[0038] The working principle of this invention is as follows: To prevent the elevator control cabinet from being bumped, it is usually placed on a rack. When testing the elevator control cabinet, it needs to be transported to the testing area together with the rack. The rack can reduce the impact on the elevator control cabinet during transportation. Since there are differences in the height of the slots on the lower end of the rack, it is necessary for the height of the pallet 6 to be changed during transportation. This application uses a motor to drive the lead screw 41 to drive the entire support to move along the frame. When the contact switch on the pallet contacts the lower end of the slot of the rack, the contact switch is triggered, causing the motor to stop moving and the elevator control cabinet to be transported as a whole. When it is transported to a convenient testing position, the rack and the elevator control cabinet are lowered together. Then, the elevator control cabinet is tested. During the test, the elevator control cabinet needs to be directly mounted using this application. First, the sliding seat 5 is driven to move by the hydraulic rod 14, so that the sliding seat 5 can keep the top plate 9 in a horizontal state. At this time, the support plate 6 will be in a downward tilting state. This application can select that the distance from the first rotating shaft 10 to the sliding seat 5 is half the distance from the second rotating shaft 11 to the sliding seat 5. In this way, when the sliding seat descends, the product of the initial angle tangent of the support plate 6 and the distance from the second rotating shaft to the sliding seat 5, the top plate and the support plate can be in a parallel state, fixing the elevator control cabinet. When the top plate 8 is horizontal, the support plate 6 tilts downward. The elevator control cabinet can be tilted by the top plate 9, and when the top plate 8 first contacts the top of the elevator control cabinet, the support plate 6 can be inserted into the lower side of the elevator control cabinet. Then, when the sliding seat 5 is driven downward by the hydraulic rod 14, the top plate 9 will tilt upward. The contact point between the elevator control cabinet and the top plate 9 will move along the lower surface of the top plate 9, so that the elevator control cabinet will gradually return to its original position. At the same time, the support plate 6 will first gradually become horizontal, and then gradually become tilted upward, completing the loading of the elevator control cabinet. No manual handling is required during the loading process, saving labor costs and reducing the labor intensity of the staff. Next, it is pushed to an open space for testing. When pushing, the actuating block 27 on the handle 24 can be held, so that the actuating block 27 drives the connecting rope 25 to move. The connecting rope 25 will pull the locking block 21 to compress the spring 20, so that the locking block 21 cannot lock the rotating wheel 23, so that the support leg 15 can rotate around the mounting shaft 18 to support the base 1. When the actuating block 27 is released, the locking block 21 will return to its original position under the action of the spring, realizing the locking. When the elevator control cabinet is moved to the testing location, by moving the toggle block 27, the application can be laid down, and the support legs will retract into the clamp 26, so that the elevator control cabinet can be tested.After testing, the pallet is moved to the placement rack using this application. When packing, the pallet is moved along with the placement rack. At this time, the pallet needs to be leveled and the upper fixed seat needs to be moved relative to the lower fixed seat so that the pallet can move the placement rack. The pallet 6 is inserted under the placement rack. At this time, the motor 44 is started. The motor 44 will drive the lead screw 41 to rotate, thereby driving the climbing block 38 to climb along the guide bar 40 and move the bracket 2. The bracket and the base are fixedly connected, so the pallet 6 will rise with the bracket until the contact switch on the upper surface of the pallet touches the lower surface of the placement rack. The contact switch is a normally closed contact and is connected in series with the main switch. When the contact switch 43 is triggered, the motor can be stopped, realizing the overall movement of the placement rack. This can be applied to placement racks of different heights and the movement effect is better.
