Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a transfer trolley for power distribution cabinets. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box) and lighting distribution cabinet (box), metering cabinet (box), which is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. At present, the distribution cabinet is mostly transferred through the corresponding transfer cart. The distribution cabinet is placed inside the transfer cart, and then the transfer operation is performed on the distribution cabinet by moving the transfer cart. For this reason, we provide a distribution cabinet transfer cart.

[0003] In the prior art, a Chinese patent document with announcement number CN220009848U and announcement date November 14, 2023 was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a distribution cabinet transfer cart, including a transfer cart body and a handle. The bottom end of the transfer cart body is provided with multiple universal wheels through bolts, and the multiple universal wheels are evenly distributed at the bottom end of the transfer cart body, and also includes a limiting mechanism.

[0004] In order to solve the problem of distribution cabinet transportation, the existing technology is to set a limit mechanism, utilize the reverse rotation of the output end of the driving motor and drive the baffle to rotate in the opposite direction and reset the limit plate through mechanical transmission. When the baffle rotates to a vertical position, the limit plate moves to contact the outer wall of the distribution cabinet, and then the transfer vehicle body can be moved as a whole by pushing the handle. This structure is conducive to clamping and limiting the distribution cabinet in transportation, but the rotation of the baffle in a vertical state is limited. When the size of the transported distribution box changes, the limit plate cannot fit tightly on the outer casing of the distribution box, which will cause the limit plate to be squeezed too tightly or not fit at all, thereby reducing the utilization rate of the transfer vehicle.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a distribution cabinet transfer trolley, including a trolley body 1, which is suitable for use in transferring the distribution cabinet. The trolley body 1 includes a load-bearing base plate 2, a pushing rod 3 is fixedly installed at the top rear end of the load-bearing base plate 2, a distribution cabinet body 4 is arranged on the top of the load-bearing base plate 2, a positioning unit is arranged on the top of the load-bearing base plate 2, and a protective unit is arranged on the inner surface of the positioning unit.

[0028] Furthermore, the positioning unit can adjust the clamping distance according to the size of the cabinet to improve the flexibility of use, and the protection unit can protect the concave and convex surfaces of the cabinet during clamping to prevent damage to the cabinet shell caused by squeezing.

[0029] Example 2

[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the positioning unit includes a movable groove 21 opened at the top of the bearing base plate 2, and positioning plates 22 are movably installed on both sides of the movable groove 21, and a motor 23 is fixedly installed on the inner bottom end of the movable groove 21 inside the bearing base plate 2, and a driving wheel 24 is fixedly installed on the output end of the motor 23, and a transmission belt 25 is movably sleeved on the outer surface of the driving wheel 24, and a driven wheel 26 is movably sleeved inside the other end of the transmission belt 25, and a rotating gear 27 is fixedly installed on the output ends of the driving wheel 24 and the driven wheel 26, and toothed brake plates 28 are meshed and connected on the outer surfaces of both sides of the rotating gear 27, one side of the toothed brake plate 28 is fixedly installed on the bottom end of the positioning plate 22, and a sliding block 29 is fixedly installed on the outer end of the toothed brake plate 28, and a limiting cross bar 210 is movably inserted inside the sliding block 29, and the limiting cross bar 210 is fixedly installed at the inner ends of the inner walls on both sides of the movable groove 21.

[0031] Furthermore, the output end of the motor 23 drives the driving wheel 24 to drive the transmission belt 25 to drive the driven wheel 26 to rotate, and then the rotating gear 27 follows the rotation. The rotation of the rotating gear 27 drives the tooth brake plates 28 on both sides to drive the positioning plates 22 on both sides to move relatively inside the movable groove 21 until they are tightly fitted on the outer shells on both sides of the distribution cabinet body 4, so that the spacing between the positioning plates 22 on both sides can be adjusted according to the size of the cabinet body, thereby improving ease of use.

[0032] Example 3

[0033] like Figure 1-5 As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the protection unit includes a buffer cavity 221 opened on the inner surface of the positioning plate 22, and limiting grooves 222 are opened on the inner walls on both sides of the buffer cavity 221, and a buffer plate 223 is movably inserted inside the buffer cavity 221, and a rubber protrusion 224 is fixedly installed on the front end outer surface of the buffer plate 223, and limiting blocks 225 are fixedly installed on the outer surfaces of both sides of the buffer plate 223, and the limiting blocks 225 are slidably installed inside the limiting grooves 222, and a reset spring 226 is fixedly installed at the rear end of the buffer plate 223, and the other end of the reset spring 226 is fixedly installed on the inner end of the buffer cavity 221.

[0034] Furthermore, when the positioning plate 22 clamps and positions the cabinet, the rubber protrusion 224 contacts the cabinet shell. The rubber material of the rubber protrusion 224 can enhance the friction between the two and promote stable positioning. When it contacts an uneven cabinet shell, the rubber protrusion 224 will move backward to squeeze the buffer plate 223, causing the buffer plate 223 to slide backward inside the buffer cavity 221 and squeeze the reset spring 226. The elastic reverse thrust of the reset spring 226 is then used to cause the buffer plate 223 and the rubber protrusion 224 to rebound and reset to fit on the cabinet shell, thereby preventing the shell from encountering uneven surfaces during clamping and reducing the extrusion damage to the cabinet shell.

[0035] The following is a detailed description of the working principle of the distribution cabinet transfer trolley.

[0036] like Figure 1-5As shown, when in use, the power distribution cabinet body 4 is placed on the top of the bearing bottom plate 2. At this time, the output end of the motor 23 drives the driving wheel 24 to drive the transmission belt 25 to drive the driven wheel 26 to rotate, so that the rotating gear 27 follows the rotation. The rotation of the rotating gear 27 drives the tooth brake plates 28 on both sides to drive the positioning plates 22 on both sides to move relatively inside the moving groove 21 until they are tightly fitted on the outer shells on both sides of the power distribution cabinet body 4, so that the spacing between the positioning plates 22 on both sides can be adjusted according to the size of the cabinet body, thereby improving the convenience of use. During the movement, the tooth brake plate 28 drives the sliding block 29 to slide on the outer surface of the limiting cross bar 210, which promotes the positioning plate 22 to move when moving. The position is limited to prevent position displacement. At the same time, when the positioning plate 22 clamps and positions the cabinet, the rubber protrusion 224 contacts the cabinet shell. The rubber material of the rubber protrusion 224 can enhance the friction between the two and promote stable positioning. When it contacts the uneven cabinet shell, the rubber protrusion 224 will move backward to squeeze the buffer plate 223, so that the buffer plate 223 moves backward and slides inside the buffer cavity 221 and squeezes the reset spring 226. The elastic reverse thrust of the reset spring 226 is then used to cause the buffer plate 223 and the rubber protrusion 224 to rebound and reset to fit on the cabinet shell, thereby preventing the shell from encountering concave and convex surfaces during clamping and reducing the extrusion damage to the cabinet shell.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
