Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, specifically to a tool and method for rapid handling of electrical distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] A handling tool is a device that can move objects to a designated area. By setting up a handling tool, objects that cannot be transported by manpower can be moved, thereby improving the ease of moving objects.

[0004] Currently, when transporting existing power distribution cabinets, the width and height of the power distribution room door are limited, and the power distribution cabinets can only be transported using flatbed forklifts. When the height of the power distribution cabinet is greater than the height of the power distribution room door, it is often impossible to move the power distribution cabinet into the power distribution room. As a result, the existing flatbed forklifts cannot perform the guiding, flipping, and enhanced positioning functions. Therefore, an improved device is needed to address the above problems. Summary of the Invention

[0015] A method for using a rapid handling tool for electrical distribution cabinets includes the following steps:

[0016] S1. First, hoist the external power distribution cabinet onto the placement rack, then start the hydraulic lifter to lift the entire power distribution cabinet. After that, pull the plug plate upwards so that the second wheel ring can disengage from the first wheel ring. Then rotate the plug plate to rotate the third gear, so that the third rack can move the placement rack inwards until the positioning cavity contacts the power distribution cabinet.

[0017] S2. Then, when the plug plate moves upward, the first button switch can be triggered, causing the first hydraulic cylinder to drive the baffle to move downward, so that the top of the distribution cabinet can be clamped and limited.

[0018] S3. Finally, first, press down the pedal so that the contact foot contacts the ground, which will brake the entire device. At the same time, when the contact foot moves downward, the first rack can be pulled away from the gear ring by the connecting rope, so that the rear plate can be released. Then, the motor can be started, driving the first gear to rotate. Through the meshing of the teeth inside the rear plate, the rear plate can be rotated as a whole, so that the rear plate and the placement frame can support the overall rotation angle of the distribution cabinet. At the same time, the rotation of the rear plate can drive the second button switch to start, so that the second hydraulic cylinder can be started at the same time, causing the second rack to move into the positioning cavity. This causes the second gear to drive the extension bracket to rotate upward, thereby increasing the support range of the positioning cavity and completing the work of adjusting the overall angle of the distribution cabinet.

[0019] The beneficial effects of this invention are:

[0020] First, the present invention, through the setting of the guiding device, can start the motor, drive the first gear to rotate, so that the rear plate as a whole can guide the power distribution cabinet to rotate at an angle through the rear plate and the placement frame. Furthermore, while the rear plate is rotating, the second hydraulic cylinder can also be activated, so that the extension bracket can be rotated to a vertical state, thereby increasing the support range of the positioning cavity, increasing the strength of the power distribution cabinet, and completing the work of guiding the power distribution cabinet to rotate at an angle.

[0021] Second, the present invention, through the combination of the first limiting device and the bearing device, can drive the positioning cavity to move towards each other when the plug plate rotates, so that the power distribution cabinet can complete the work of precise horizontal positioning. At the same time, when the plug plate moves upward, the first hydraulic cylinder can be activated by the first button switch, causing the baffle to move downward to fit with the top of the power distribution cabinet, so that the top of the power distribution cabinet can be limited, and the work of power distribution enhanced stability positioning can be completed.

[0036] The invention will be further described below with reference to the accompanying drawings.

The guide device 6 includes a front plate 8, auxiliary rollers 9, a first spring 10, a first rack 11, a motor 12, and a first gear 13. The auxiliary rollers 9 are rotatably installed on both ends of the front plate 8, and the first springs 10 are symmetrically fixed. The first rack 11 is fixedly installed on the opposite end of the first spring 10, and the motor 12 is fixedly installed on the rear end of the front plate 8.

The drive roller 18 is fixedly installed on the bottom front end of the hydraulic lifter 14. The hydraulic lifter 14 is fixedly installed on the top front end of the base frame 16. The contact feet 17 are symmetrically slidably inserted into the top front end of the base frame 16, and the contact feet 17 are located at both ends of the hydraulic lifter 14. The connecting rope 15 is fixedly connected to the top end of the contact feet 17.

[0039] like Figure 6 The limiting component 5 includes a first limiting device 19, a second limiting device 20, and a supporting device 21. The first limiting device 19 is fixedly installed on the top of the supporting device 21, and the second limiting device 20 is fixedly installed on the top of both ends of the supporting device 21, which can support the first limiting device 19 to perform the limiting work.

[0040] like Figure 7 The first limiting device 19 includes a first hydraulic cylinder 22, a first push-button switch 23, a baffle 24, a base frame 25, a cover plate 26, a first wheel rim 27, and a second push-button switch 28. The first hydraulic cylinder 22 is fixedly installed at both ends inside the base frame 25. The baffle 24 is fixedly installed between the two first hydraulic cylinders 22. The base frame 25 is fixedly installed on the top of the cover plate 26. The second push-button switch 28 is symmetrically fixedly installed on the front end of the cover plate 26. The first wheel rim 27 is fixedly installed at the top center of the cover plate 26. The first push-button switch 23 is fixedly installed on the top of the cover plate 26 and is located on the rear end of the first wheel rim 27. The bottom of the front end of the second push-button switch 28 is set in an arc state, which improves the smoothness of the second push-button switch 28 when passing the rear end of the front plate 8.

[0041] like Figure 8 The second limiting device 20 includes an extension bracket 29, a second gear 30, a second rack 31, a second hydraulic cylinder 32, and a positioning cavity 33. The second hydraulic cylinder 32 is symmetrically fixedly installed inside the rear end of the positioning cavity 33. The second rack 31 is symmetrically fixedly installed on the rear end of the second hydraulic cylinder 32. The second gear 30 is symmetrically rotated and installed inside the rear end of the positioning cavity 33. The extension bracket 29 is fixedly connected to the front end of the second gear 30. When the second hydraulic cylinder 32 is in a normal state, it can drive the second rack 31 to move towards the rear end of the positioning cavity 33, so that the extension bracket 29 can be reset and retracted into the positioning cavity 33.

[0042] like Figure 9 The supporting device 21 includes a placement frame 34, a guide rail 35, a third rack 36, a third gear 37, a second wheel ring 38, an insert plate 39, a gear ring 40, a support ring 41, and a rear plate 42. The rear plate 42 is fixedly installed on the top front end of the placement frame 34. The support ring 41 and the gear ring 40 are respectively fixedly installed on the front front surface of the rear plate 42, and the gear ring 40 is located on the outer ring of the support ring 41. The third gear 37 is rotatably installed on the top center of the rear plate 42. The insert plate 39 is slidably inserted into the top interior of the third gear 37. The second wheel ring 38 is fixedly installed on the bottom outer ring of the insert plate 39. The third rack 36 meshes with the front and rear ends of the third gear 37. The placement frame 34 is fixedly installed on the end of the third rack 36 away from the third gear 37. The guide rail 35 is symmetrically fixedly installed inside the top of the rear plate 42. The support ring 41 is rotatably installed in the rotating groove inside the rear end of the front plate 8, so that the rear plate 42 can be rotated and adjusted.

[0043] The front end of the front plate 8 is fixedly mounted on the top of the hydraulic lifter 14. The end of the connecting rope 15 away from the contact foot 17 is fixedly connected to the side end of the first rack 11 away from the first gear 13. The cover plate 26 is fixedly mounted on the top of the rear plate 42. The positioning cavity 33 is fixedly mounted on the end of the placement frame 34 away from the third rack 36. The support ring 41 is rotatably mounted inside the rear end of the front plate 8 to prevent the rear plate 42 from falling off.

[0044] A locking key is fixedly installed on the front end of the first rack 11, and the rear sides of the front plate 8 are provided with locking grooves that match the locking key. The rear end of the front plate 8 is provided with a rotating groove that matches the support ring 41. The second push-button switch 28 is electrically connected to the second hydraulic cylinder 32. When the device is not supporting the power distribution cabinet, the first hydraulic cylinder 22 and the second hydraulic cylinder 32 can be started separately to drive the second rack 31 to reset and the baffle 24 to reset.

[0045] The first button switch 23 is electrically connected to the first hydraulic cylinder 22. Magnetic blocks are fixedly installed on the top outer ring of the first wheel rim 27 and the bottom outer ring of the second wheel rim 38, and the magnetic blocks are staggered. Teeth are fixedly installed at the front center of the rear plate 42, and the teeth are distributed at an angle of 360°. When the first gear 13 rotates, it can drive the rear plate 42 to rotate and adjust as a whole.

[0046] A method for using a rapid handling tool for electrical distribution cabinets includes the following steps:

[0047] S1. First, hoist the external power distribution cabinet onto the placement frame 34, then start the hydraulic lifter 14 to lift the entire power distribution cabinet using the placement frame 34. After that, pull the plug plate 39 upward so that the second wheel 38 can disengage from the first wheel 27. Then rotate the plug plate 39 to rotate the third gear 37 so that the third rack 36 can move the placement frame 34 inward until the positioning cavity 33 contacts the power distribution cabinet.

[0048] S2. Then, when the plug plate 39 moves upward, the first button switch 23 can be triggered, causing the first hydraulic cylinder 22 to drive the baffle 24 to move downward, so that the top of the power distribution cabinet can be clamped and limited.

[0049] S3. Finally, first, press down pedal 2 so that contact foot 17 contacts the ground, which can brake the entire device. At the same time, when contact foot 17 moves downward, the first rack 11 can be pulled away from the gear ring 40 by connecting rope 15, so that the rear plate 42 can be released. Then, the motor 12 can be started, driving the first gear 13 to rotate. Through the meshing of the teeth inside the first gear 13 and the rear plate 42, the rear plate 42 can be rotated as a whole, so that the rear plate 42 and the placement frame 34 can support the overall rotation angle of the power distribution cabinet. At the same time, the rotation of the rear plate 42 can drive the second button switch 28 to start, so that the second hydraulic cylinder 32 can be started at the same time, causing the second rack 31 to move into the positioning cavity 33, so that the second gear 30 will drive the extension bracket 29 to rotate upward, thereby increasing the support range of the positioning cavity 33 and completing the work of adjusting the overall angle of the power distribution cabinet.

[0050] The working principle of Embodiment 1 is as follows: During use, the distribution cabinet is hoisted to the top of the placement frame 34 using external hoisting equipment. Then, the hydraulic lifter 14 can be activated, causing the front plate 8 and the rear plate 42 to move upwards simultaneously, resulting in the placement frame 34 lifting the entire distribution cabinet. At the same time, the insert plate 39 can be pulled upwards until the third rack 36 disengages from the first wheel rim 27, allowing the third gear 37 to be released. Simultaneously, as the insert plate 39 moves, the hexagonal prism at the bottom of the insert plate 39 slides in the hexagonal groove inside the top of the third gear 37, ensuring that the insert plate 39 moves in a straight line. When the insert plate 39 moves upwards to its limit position, it can contact the first button switch 23, causing the first hydraulic cylinder 22 to open and drive... The baffle 24 moves downward until it is flush with the top of the distribution cabinet, pressing the cabinet between the mounting bracket 34 and the baffle 24, thus limiting the upper and lower ends of the cabinet. Then, the insert plate 39 can be rotated, causing the third gear 37 to rotate. When the third gear 37 rotates, it causes the two third racks 36 to move inwards towards each other until the positioning cavity 33 contacts the surface of the distribution cabinet. At this point, the insert plate 39 can be moved downward, causing the magnetic block at the bottom of the second wheel rim 38 to engage with the magnetic block at the top of the first wheel rim 27, preventing the insert plate 39 from rotating again and completing the limiting work on both sides of the distribution cabinet. Simultaneously, the third racks 36 move and slide onto the guide rail 35 via the mounting bracket 34, ensuring the positioning... The positioning cavity 33 moves in a straight line, improving the contact accuracy between the positioning cavity 33 and the distribution cabinet. After the distribution cabinet is in position, the drive roller 18 can be activated to move the base frame 16 as a whole, allowing the distribution cabinet to be moved to the designated position. When the distribution cabinet needs to rotate, the pedal 2 can be pressed down, causing the contact foot 17 to contact the ground, thereby braking the drive roller 18 and preventing the base frame 16 from moving again. While the contact foot 17 moves downward, the connecting rope 15 can pull the first rack 11 to move outward in opposite directions, causing the first rack 11 to disengage from the gear ring 40 and releasing the rear plate 42. At this time, a locking key is fixedly installed on the front end of the first rack 11, and the rear end of the front plate 8 is symmetrically provided with locking mechanisms that match the locking key. The slot allows the first rack 11 to slide within the slot during movement, ensuring its linear movement. When the rear plate 42 is released, the motor 12 is started, rotating the first gear 13. The first gear 13 meshes with the teeth inside the front end of the rear plate 42, causing the rear plate 42 and the placement rack 34 to rotate as a whole, adjusting the angle of the distribution cabinet. Simultaneously, the rotation of the rear plate 42 rotates the cover plate 26, causing it to contact the rear end of the front plate 8, triggering the second hydraulic cylinder 32. This second hydraulic cylinder 32 then moves the second rack 31 towards the front end of the positioning cavity 33.The second rack 31 meshes with the bottom end of the second gear 30, and the second gear 30 is rotatably mounted inside the positioning cavity 33. When the second rack 31 passes the bottom end of the second gear 30, it drives the second gear 30 to rotate upwards. When the second rack 31 has moved its full range of motion at the bottom end of the second gear 30, the top end of the rear end of the second rack 31 will be vertically aligned with the bottom end of the second gear 30. This allows the extension bracket 29 to rotate to a vertical position, thereby causing the two extension brackets 29 to respectively contact the surface of the distribution cabinet, lifting the positioning cavity 33. The support range of 33 improves the stability of the positioning cavity 33 when supporting the power distribution cabinet. When the rear plate 42 and the placement rack 34 rotate the power distribution cabinet to the designated position, the pedal 2 can be released. The elasticity of the first spring 10 will drive the first rack 11 to move inward and reset quickly until the first rack 11 meshes with the outer ring of the gear ring 40 again, so that the rear plate 42 can be fixed at the designated angle. At the same time, when the first rack 11 moves and resets, it can also pull the connecting rope 15 to drive the contact foot 17 to move upward and reset, completing the work of releasing the brake.

[0051] Example 2

[0052] Based on Example 1, such as Figure 10 As shown, the placement frame 34 also includes an auxiliary frame 43, a slide rod 44, a second spring 45, a positioning sleeve 46, and a connecting rod 47. The positioning sleeve 46 is fixedly installed on both sides of the rear end of the placement frame 34. The second spring 45 is fixedly installed in the inner center of the positioning sleeve 46. The slide rod 44 slides through the positioning sleeve 46 and is fixedly installed on the second spring 45. The connecting rod 47 slides through the positioning sleeve 46 and is fixedly installed on the slide rod 44. The auxiliary frame 43 is symmetrically rotated and installed inside the rear end of the placement frame 34.

[0053] In implementing this embodiment, when the distribution cabinet needs to be removed, the connecting rod 47 can be pulled outwards until the sliding rod 44 moves out of the auxiliary frame 43 and the placement frame 34, allowing the auxiliary frame 43 to be released. At this time, the auxiliary frame 43 can be rotated rearwards until it contacts the ground, allowing the auxiliary frame 43 to be placed at an angle. Rollers are equidistantly mounted on both sides of the top of the placement frame 34, making it easy for the distribution cabinet to slide off the top of the placement frame 34. At the same time, the tilt of the auxiliary frame 43 with respect to the ground prevents the distribution cabinet from falling directly to the ground, thus completing the removal of the distribution cabinet. When the distribution cabinet is supported by the placement frame 34, the connecting rod 47 can be pulled outwards, so that the sliding rod 44 can be moved out of the auxiliary frame 43 and the placement frame 34. Then, the auxiliary frame 43 is rotated upwards until the alignment hole inside the bottom of the auxiliary frame 43 is horizontally aligned with the sliding rod 44. Then, the connecting rod 47 is released, and the elasticity of the second spring 45 will drive the sliding rod 44 to move into the placement frame 34 until the sliding rod 44 is inserted into the alignment hole inside the auxiliary frame 43, so that the auxiliary frame 43 can be placed in a vertical state, improving the placement stability of the rear end of the distribution cabinet.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

A method of using a rapid handling tool for power distribution cabinets, comprising the rapid handling tool for power distribution cabinets described in claim 7, characterized in that, It includes the following steps: S1. First, hoist the external power distribution cabinet onto the placement rack (34), then start the hydraulic lifter (14) to drive the placement rack (34) to lift the power distribution cabinet as a whole. After that, pull the plug plate (39) upward so that the second wheel (38) can be disengaged from the first wheel (27). Then rotate the plug plate (39) to drive the third gear (37) to rotate so that the third rack (36) can drive the placement rack (34) to move inward until the positioning cavity (33) contacts the power distribution cabinet. S2. Afterwards, when the plug plate (39) moves upward, the first button switch (23) can be triggered, causing the first hydraulic cylinder (22) to drive the baffle (24) to move downward, so that the top of the power distribution cabinet can be clamped and limited. S3. Finally, first, press down the pedal (2) so that the contact foot (17) contacts the ground, which can brake the entire device. At the same time, when the contact foot (17) moves downward, the first rack (11) can be pulled away from the gear ring (40) by the connecting rope (15), so that the rear plate (42) can be released. Then, the motor (12) can be started to drive the first gear (13) to rotate. Through the meshing of the teeth of the first gear (13) with the teeth inside the rear plate (42), the rear plate (42) can be adjusted. The entire structure rotates, allowing the rear plate (42) and the placement rack (34) to support the overall rotation angle of the distribution cabinet. Simultaneously, the rotation of the rear plate (42) activates the second button switch (28), which in turn activates the second hydraulic cylinder (32), causing the second rack (31) to move into the positioning cavity (33). This causes the second gear (30) to drive the extension bracket (29) to rotate upward, thereby increasing the support range of the positioning cavity (33) and completing the overall angle adjustment of the distribution cabinet.
