Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker transportation vehicles, and in particular to an anti-tipping transfer vehicle. Background Technology

[0002] During installation and maintenance, KYN high-voltage switchgear handcart-type vacuum circuit breakers require transport by a trolley. However, due to their high center of gravity, they are prone to tipping over during forward and backward movement, causing the circuit breaker to fall and be damaged. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a mobile, stable, and anti-tipping transfer vehicle.

[0004] This utility model is achieved through the following technical solution:

[0005] An anti-tipping transfer vehicle includes four support legs, each with a roller at its lower end. The vehicle is characterized by a mounting plate between the front and rear support legs on both sides. A front support plate and a rear support plate are guided onto the mounting plate. The front support plate has an upper rack, and the rear support plate has a lower rack. The upper and lower racks are connected by a transmission gear. A tension spring is provided between the front support plate and the front support leg, or between the rear support plate and the rear support leg.

[0006] The transmission gears on the left and right sides are connected by a transmission shaft.

[0007] Both the front support plate and the rear support plate are lifted off the ground.

[0008] The front support plate has an upper guide hole and a middle guide hole. Both the front and rear support plates have lower guide holes. The two lower guide holes are at the same height. The mounting plate is provided with two upper guide sleeves and two lower guide sleeves. The two upper guide sleeves are located in the upper guide holes, the transmission gear is located in the middle guide hole, and the lower guide sleeve is located in the lower guide hole.

[0009] The beneficial effects of this utility model are:

[0010] This utility model is equipped with a front support plate and a rear support plate. During the transfer process, the front and rear ends of the front and rear support plates extend outside the transfer vehicle, increasing the bottom area of ​​the transfer vehicle and thus effectively preventing the transfer vehicle from tipping over.

[0011] The front and rear support plates of this utility model are both raised off the ground, so as not to affect the transportation of the transfer vehicle.

[0012] This utility model is equipped with a tension spring. After entering the switch cabinet, the front support plate retracts by the cabinet body and pushing force, without affecting the installation of the circuit breaker.

[0013] This invention uses gear and rack transmission during the transmission process, which is stable and reliable; the support plates on both sides are provided with rebound force by tension springs on both sides, and the support plates on both sides are connected in series by the transmission shaft, so the failure of one side will not affect the use.

Detailed Implementation

[0020] The attached figure shows a specific embodiment of this utility model.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1 to 4As shown, this anti-tipping transport vehicle includes four support legs 1, each with a roller 2 mounted on its lower end. A mounting plate 3 is fixedly installed between the front and rear support legs 1 on both the left and right sides. Two upper guide sleeves 6 and two lower guide sleeves 6 are mounted on the mounting plate 3. The two upper guide sleeves 6 are positioned front-to-back on the mounting plate 3, and the two lower guide sleeves 6 are positioned rear-to-back on the mounting plate 3. A front support plate 4 and a rear support plate 5 are mounted on the mounting plate 3. The front support plate 4 has an upper guide hole 7, a middle guide hole 8, and a lower guide hole 9. The rear support plate 5 has a lower guide hole 9. The two lower guide holes 9 are at the same height and partially overlap. The two upper guide sleeves 6 are located within the upper guide holes 7, and the two lower guide sleeves 6 are located within the overlapping portion of the two lower guide holes 9.

[0024] The preferred solution is to lift both the front support plate 4 and the rear support plate 5 off the ground to avoid affecting the transport of the transfer vehicle.

[0025] A transmission gear 10 is installed on the mounting plate 3, an upper rack 11 is installed on the front support plate 4, and a lower rack 12 is installed on the rear support plate 5. The transmission gear 10 is meshed with the upper rack 11 and the lower rack 12 respectively, and the transmission gear 10 is located in the middle guide hole 8.

[0026] The preferred solution is that the two transmission gears 10 on the left and right are connected by a transmission shaft 13 to achieve linkage.

[0027] The upper guide hole 7, the middle guide hole 8, and the lower guide hole 9 are all elongated to allow the front support plate 4 and the rear support plate 5 to move.

[0028] A tension spring 14 is provided between the front support plate 4 and the front support leg 1 or between the rear support plate 5 and the rear support leg 1. Preferably, the tension spring 14 is installed between the front support plate 4 and the front support leg 1.

[0029] When the tension spring 14 is connected to the drive shaft 13, it can be installed on only one side.

[0030] The usage process is as follows:

[0031] Under normal conditions, the front support plate 4 extends forward under the action of the tension spring 14, and through the transmission gear 10 and rack, drives the rear support plate 5 to extend backward, increasing the bottom area of ​​the transfer vehicle, increasing stability, and preventing the transfer vehicle from tipping over.

[0032] After the transfer vehicle transfers the vacuum circuit breaker 0 into the switch cabinet, the front support plate 4 contacts the cabinet. As it pushes forward, the front support plate 4 does not move. The transfer vehicle continues to move forward, and through the transmission gear 10 and the two racks, the rear support plate 5 retracts together. The tension spring 14 stretches, and the front support plate 4 and the rear support plate 5 completely retract into the range of the front and rear support legs 1, without affecting the installation of the vacuum circuit breaker 0.

[0033] After installation, the transport vehicle is removed, and under the action of the tension spring 14, the front support plate 4 and the rear support plate 5 extend again.
