Description

Technical Field

[0001] This utility model relates to the field of handcart pushing vehicle technology, specifically a handcart pushing vehicle for a centrally located switchgear. Background Technology

[0002] When the trolley of the central switchgear slides in or out, the drive rod in the trolley needs to be manually cranked. In order to improve the safety of the trolley sliding in or out, the existing technology uses a pusher with a special sleeve to drive the drive rod to rotate, which replaces the drive rod in the hand-cranked switchgear trolley.

[0003] In the prior art, such as the electrical control switchgear trolley pusher proposed in patent application number "CN202420145414.2", there is a vehicle body, and an installation tube is fixed on the upper surface of the vehicle body; a lifting block is provided on the installation tube, and an installation hole is provided at the upper end of the lifting block. A motor is provided in the installation hole, and the motor is connected to a special sleeve through a coupling. The axis of the special sleeve is set horizontally, and the special sleeve can be sleeved on the drive rod of the switchgear trolley and cooperate with the drive rod of the switchgear trolley.

[0004] However, in the existing handcart propulsion vehicle technology, when driving the control levers at different heights, it is necessary to loosen the bolts and adjust the height together with the motor, lifting block and special sleeve. The counterweight of the motor and lifting block makes it more difficult to adjust the height of the special sleeve, which is inconvenient to use. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 A handcart for pushing a centrally located switch cabinet includes a car body 1 with self-locking wheels 2 installed at the bottom. A support frame 3 is fixedly connected to the top of the car body 1. The inside of the support frame 3 is a cavity. Multiple drive mechanisms 4 are arranged inside the support frame 3. The multiple drive mechanisms 4 are equidistantly arranged in the vertical direction. Each drive mechanism 4 includes a rotatable drive column 403. The cross-section of the drive column 403 is a regular hexagon.

[0025] like Figure 1-4 A rectangular opening 5 is provided on one side of the support frame 3. A horizontally movable frame 6 is provided on the outside of the rectangular opening 5. A support plate 7 is slidably connected to the movable frame 6, so that the support plate 7 can move up and down on the movable frame 6. A matching sleeve rod 9 is rotatably connected to the support plate 7 through a bearing 8. The matching sleeve rod 9 is compatible with the drive column 403.

[0026] The interior of the mating sleeve rod 9 is a cavity with a regular hexagonal cross-section. One end of the drive column 403 is attached to the inner wall of the mating sleeve rod 9, so that when the drive column 403 rotates, it can drive the mating sleeve rod 9 to rotate. One end of the mating sleeve rod 9 is fixedly connected to a special sleeve 10. The special sleeve 10 is used to drive the drive rod of the external center-mounted switchgear to rotate. The special sleeve 10 can be fitted onto the drive rod of the external center-mounted switchgear.

[0027] like Figure 4The drive mechanism 4 also includes a drive shaft 401, which is rotatably connected to the inner wall of the support sleeve 3. A mating gear 402 is fixedly connected to the outer surface of the drive shaft 401. One end of the drive shaft 401 is fixedly connected to the drive column 403, so that the drive shaft 401, the mating gear 402 and the drive column 403 can rotate together. Two adjacent mating gears 402 located at different heights mesh, and transmission is carried out through the meshing between the mating gears 402, so that all the drive mechanisms 4 can rotate together.

[0028] like Figure 3 and Figure 4 A servo motor 11 is fixedly installed on the top of the vehicle body 1. The servo motor 11 is a prior art technology and can rotate in different directions. When it is necessary to drive the special sleeve 10 to rotate through the drive mechanism 4 at different heights, the direction of the servo motor 11 can be adjusted accordingly. The output end of the servo motor 11 is fixedly connected to a rotating rod 12. One end of the rotating rod 12 extends into the support frame 3 and is fixedly connected to a drive pulley 13.

[0029] like Figure 4 A driven pulley 14 is fixedly connected to the lowest drive column 403. A transmission belt 15 connects the drive pulley 13 and the driven pulley 14. The drive pulley 13 and the driven pulley 14 are the same size and can be connected by transmission belt 15.

[0030] like Figure 1 and Figure 2 Multiple positioning protrusions 16 are fixedly connected to the outer surface of the support frame 3 and on both sides of the rectangular opening 5. The positioning protrusions 16 and the drive mechanism 4 are correspondingly arranged. Two positioning protrusions 16 of corresponding height are arranged on the outer side of the drive mechanism 4 at different heights. The multiple positioning protrusions 16 are equidistantly arranged. The support plate 7 is provided with positioning slots that cooperate with the positioning protrusions 16. The positioning protrusions 16 can be inserted into the positioning slots to assist in positioning the support plate 7.

[0031] like Figure 1 and Figure 2 An electric telescopic rod 18 is fixedly installed on the top of the support frame 3. A power supply (not shown in the figure) is installed on the vehicle body 1. Both the electric telescopic rod 18 and the servo motor 11 can be connected to the power supply for power. One end of the electric telescopic rod 18 is fixedly connected to the movable frame 6 to drive the movable frame 6 to move horizontally. Push handles 19 are fixedly connected to both sides of the support frame 3 to facilitate manual pushing of the support frame 3, which drives the support frame 3 and the vehicle body 1 to move and operate the central switch cabinet in different positions.

[0032] The working principle of the handcart pushing vehicle for a centrally located switchgear provided by this utility model is as follows:

[0033] When the height of the special sleeve 10 needs to be adjusted, the electric telescopic rod 18 extends and pushes the movable frame 6. The movable frame 6 drives the support plate 7 to move, so that the support plate 7 and the positioning protrusion 16 are separated. At the same time, the support plate 7 drives the mating sleeve 9 and the drive column 403 to separate.

[0034] Then adjust the height of the support plate 7 up and down, adjust the height of the special sleeve 10, and then retract the electric telescopic rod 18 to drive the movable frame 6 and the support plate 7 to move. The support plate 7 drives the cooperating sleeve 9 to move, and the cooperating sleeve 9 can be fitted onto the drive column 403 at different heights.

[0035] When it is necessary to rotate the drive rod of the external central switchgear, manually grasp the push handle 19 and push the support sleeve 3 and the vehicle body 1 so that the special sleeve 10 is fitted onto the drive rod of the external central switchgear. The servo motor 11 drives the drive pulley 13 to rotate through the rotating rod 12. The drive pulley 13 drives the driven pulley 14 to rotate through the transmission belt 15. The driven pulley 14 drives the lowest drive shaft 401 to rotate. The drive shaft 401 drives the mating gear 402 and the drive column 403 to rotate. Under the meshing action of the mating gears 402 on different drive mechanisms 4, all the drive columns 403 rotate together. The drive column 403 drives the mating sleeve 9 on it to rotate. The mating sleeve 9 drives the special sleeve 10 to rotate. The special sleeve 10 drives the drive rod of the external central switchgear to rotate, so that the handcart of the external central switchgear slides in or out.

[0036] Compared with related technologies, the handcart pushing vehicle for a centrally located switchgear provided by this utility model has the following beneficial effects:

[0037] This invention lowers the center of gravity of the vehicle body 1 by mounting the servo motor 11, which serves as the power output, making the vehicle body 1 more stable during movement. At the same time, the support plate 7 can drive the cooperating sleeve 9 and the special sleeve 10 to move up and down independently, allowing operation of the centrally located switchgear at different heights of the drive rod. When adjusting the height of the special sleeve 10, it is not necessary to drive the servo motor 11 to move up and down together, nor is it necessary to install operating bolts, making the height adjustment of the special sleeve 10 more convenient and labor-saving.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
