Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet transportation, and more specifically to a transportation device for high and low voltage switch cabinet production. Background Art

[0002] High and low voltage switchgear is equipment for connecting high voltage or low voltage cables. Generally, power supply bureaus and substations use high voltage cabinets, which are then stepped down by transformers to low voltage cabinets. The low voltage cabinets are then sent to distribution boxes for various electricity users. Inside, some protective devices such as switches and circuit breakers are assembled into one electrical device.

[0003] At present, each movement of switch cabinets in production requires the use of a crane for lifting and moving, which is relatively cumbersome during the movement process. In the existing patent CN217320454U, a transfer device for switch cabinets is used. When transferring the switch cabinet, it is only necessary to move the lifting plate from the second position to the first position to form a slope with the ground, and then push the switch cabinet into the accommodating cavity along the slope, and then move the lifting plate from the first position to the second position to transfer the switch cabinet. Compared with the existing transfer device that requires the installation of a lifting ring on the switch cabinet, this device is more convenient in use, but if the bottom plate is too high, the slope needs to be longer to ensure that the slope is flat. It is easy to install the switch cabinet, but the loading and unloading time will become longer, affecting the work efficiency. In view of this, we propose a transfer device for the production of high and low voltage switch cabinets. Utility Model Content

When shipping the high and low voltage switch cabinets, the bottom plate 2 is placed on the ground. After installation, the lifting mechanism is used to drive the bottom plate 2 to rise and leave the bottom surface for transportation. The height of the bottom plate 2 can be adjusted as needed. Two guide plates 3 are relatively arranged at one end of the outer side of the bottom plate 2. The top surface of the guide plate 3 is an inclined surface. The setting of the guide plate 3 facilitates the high and low voltage switch cabinets to move to the top surface of the bottom plate 2.

The second frames 102 can limit the two sides of the high and low voltage switch cabinets to facilitate stability during movement. A moving wheel assembly is arranged at the bottom of the second frame 102 to drive the device to move;

[0028] The lifting mechanism is disposed in the first frame 101 ; the bottom plate 2 is disposed between the two second frames 102 , and the lifting mechanism drives the bottom plate 2 to move up and down.

[0029] In the present application, the lifting mechanism includes a chain 4, a mounting groove 103 is opened in the first frame 101, one end of the chain 4 is connected to the mounting groove 103, and the other end is connected to the base plate 2, and the lifting of the chain 4 drives the base plate 2 to rise and fall.

[0030] Among them, a cylinder 5 is arranged in the installation groove 103, and a fixed seat 6 is arranged on the output shaft of the cylinder 5. A sprocket 7 is rotatably connected to the fixed seat 6, and the sprocket 7 is engaged with the chain 4. The lifting and lowering of the cylinder 5 drives the fixed seat 6 and the sprocket 7 to rise and fall. Since the sprocket 7 is engaged with the chain 4, the sprocket 7 will rotate when it is lifted and lowered, and one end of the chain 4 is fixed in the installation groove 103, so the other end of the chain 4 will rise and fall, thereby driving the base plate 2 to rise and fall.

[0031] In the present application, a connecting plate 301 is provided inside the guide plate 3, a slider 10 is provided on one side of the connecting plate 301, a slide groove A104 is provided on the first frame 101, and the slider 10 slides with the slide groove A104. When one end of the chain 4 is lifted or lowered, the slider 10 is pulled to move along the slide groove A104, and a limit bar is provided at one end of the slider 10 located in the slide groove A104 to limit the position of the slider 10 and prevent the slider 10 from escaping from the slide groove A104. Under the limiting action of the slider 10, the side wall of the connecting plate 301 can move up and down on the surface of the first frame 101, and the connecting plate 301 has a certain thickness, and the side wall is a vertical plane to ensure that the bottom plate 2 is in a horizontal state.

[0032] In the present application, a slide groove B105 is provided on the second frame 102, and a limiting column 11 is provided in the slide groove B105. The limiting column 11 passes through the slide groove B105 and extends to the inner side of the second frame 102, wherein the limiting column 11 can slide along the slide groove B105, and the high and low voltage switch cabinets located on the bottom plate 2 are limited by the position of the limiting column 11, so that they can move stably during the transportation process. The side of the limiting column 11 that contacts the high and low voltage switch cabinets can be bonded with a rubber pad to protect the surface of the switch cabinet.

[0033] In the present application, a limiting plate 12 is provided at the outer end of the limiting column 11, and a fixing screw 13 is penetrated through the limiting plate 12. The position of the limiting plate 12 on the second frame 102 is fixed by the fixing screw 13, so that the position of the limiting column 11 is fixed, and the position of the limiting column 11 is adjusted according to the size of the high and low voltage switch cabinets.

It is convenient for the chain 4 to pull the connecting plate 301 to move, wherein the width of the connecting plate 301 is greater than the width of the chain 4, so that there is a gap between the chain 4 and the inner wall of the groove in the middle of the connecting plate 301, so that when the high and low voltage switch cabinets are in contact with the connecting plate 301, the chain 4 will not contact the surface of the high and low voltage switch cabinets, thereby preventing the chain 4 from rubbing and damaging the high and low voltage switch cabinets.

[0035] In a possible embodiment, the lifting mechanism can be set to two or more groups, and the connection method of each group of lifting mechanisms is the same as the above method, wherein the cylinders in each group of lifting mechanisms can be controlled by a control mechanism to achieve simultaneous opening or closing.

[0036] Working principle: When loading and unloading high and low voltage switch cabinets, the utility model removes the limit column 11, uses the cylinder 5 to drive the fixed seat 6 and the sprocket 7 to descend, because the sprocket 7 is meshed with the chain 4, so when the sprocket 7 descends, the end of the chain 4 connected to the connecting plate 301 will also descend due to gravity, and when the chain 4 descends, the force acting on the sprocket 7 will cause the sprocket 7 to rotate, and the other end of the chain 4 is fixed in the installation groove 103. When the bottom plate 2 is lowered to contact with the ground, the cylinder 5 is closed, and the two ends of the high and low voltage switch cabinets are pushed from the two guide plates 3 to the top surface of the bottom plate 2; then the limit column 11 is inserted into the slide groove B105, and the limit column 11 at one end is in contact with the surface of the high and low voltage switch cabinet, and then the fixing screw 13 is tightened. Finally, the cylinder 5 is used to drive the fixed seat 6 and the sprocket 7 to rise, so that the bottom plate 2 leaves the ground and has a certain distance from the ground, which is convenient for the transportation of the high and low voltage switch cabinets.
