Technical Field

[0001] The utility model relates to the technical field of electrical devices, in particular to an electrical device lifting and transferring device. Background Art

[0002] Electrical devices mainly refer to: equipment in transformer substations and distribution substations and locally dispersed power and lighting distribution boxes. During the transfer and lifting of electrical devices, damage to the equipment should be avoided as much as possible, especially important electrical components. Since electrical devices are generally large in size, in order to make the electrical devices stable during transfer and lifting, an electrical device lifting and transfer device is designed.

[0003] After searching the Chinese patent with publication number CN211004370U, a lifting and transferring device for an electrical device is disclosed, which relates to the field of electrical devices, including a supporting trolley, a lifting structure and a limiting structure. The top side of the supporting trolley is provided with a lifting structure, and the limiting structure is provided on the top side of the lifting structure. By providing the lifting structure, the active bevel gear is driven to rotate in cooperation with the operation of the servo motor, and the screw rod is rotated by cooperating with the bevel gear. By cooperating with the operation of the bevel gear, the two sliders are moved to both sides along the slide rail at the same time through thread cooperation. The lifting of the lifting rod is achieved with the cooperation of the lifting rod, and the lifting operation of the electrical device is achieved through the limiting structure. The lifting operation can be performed on the electrical device as a whole, and the lifting stability is better, thereby ensuring the stability of the movement of the electrical device. By providing the limiting structure, the clamping and positioning of the electrical device is achieved with the clamping cooperation of the folding plates on both sides, thereby ensuring that the electrical device is in a stable state during movement, thereby ensuring the smooth movement of the electrical device.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing transfer and lifting device uses a spring to tighten the lifting plate when fixing the electrical device so that the folding plates on both sides can clamp and fix the electrical device. However, the tightening force of the spring is limited, resulting in a relatively low clamping force of the folding plate. When the electrical device is lifted, it may shift or even fall off, so there are limitations. Utility Model Content

Based on the embodiments of 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.

[0025] The utility model provides an electrical device lifting and transferring device through improvement. The technical solution of the utility model is:

[0026] like Figure 1-Figure 3 As shown, an electrical device lifting and transferring device comprises a groove plate 1 and a groove plate 2 3, one side of the groove plate 1 is fixedly connected with a pull rod 2, pulling the pull rod 2 can drive the device to move, a clamping assembly is arranged on the groove plate 2 3, the clamping assembly comprises two clamping blocks 6, the clamping block 6 close to the pull rod 2 is fixedly connected to the groove plate 2 3, the clamping block 6 away from the pull rod 2 is slidably connected to the groove plate 2 3, the opposite sides of the two clamping blocks 6 are fixedly connected with rubber pads 4, when the electrical device is placed on the groove plate 2 3, the clamping block 6 away from the pull rod 2 moves until the two clamping blocks 6 are tightly fitted with the surface of the electrical device and stop moving, the rubber pads 4 can improve the clamping effect of the device, and also help to protect the device from scratches on the surface of the device during clamping, and also include;

[0027] A lifting assembly, the lifting assembly includes a cross support 14 disposed between the groove plate 1 and the groove plate 2 3, and the cross support 14 can move the groove plate 2 3 when it rises and falls, so that the groove plate 2 3 can complete the loading and unloading of the electrical device at different heights;

[0028] The locking assembly includes four guide rods 13 fixedly connected to the top corners of the groove plate 1, the guide rods 13 are slidably connected to the groove plate 2 3, and the top of the guide rods 13 is fixedly connected to the limit block 17. The setting of the guide rods 13 helps to make the groove plate 2 3 more stable when it is raised and lowered, and the setting of the limit block 17 can limit the movement of the groove plate 2 3.

[0029] Furthermore, a slide groove is opened at the middle end of the groove plate 2 3, and a threaded rod 7 is rotatably installed in the slide groove. The end of the threaded rod 7 is fixedly connected to a worm gear 9. The rotation of the worm gear 9 drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 can drive the clamping block 6 adjacent to the worm gear 9 to move, so that the two clamping blocks 6 clamp the electrical device.

[0030] Furthermore, two sleeves 8 are fixedly connected to one side of the groove plate 2 3 adjacent to the worm gear 9, and a worm 91 meshing with the worm gear 9 is rotatably connected between the two sleeves 8.

When the groove plate 23 is lifted to the specified position, the latch 11 is inserted into the locking hole 121, so that the force on both sides of the groove plate 23 is concentrated on the latch 11, so that the force on the cross support 14 is reduced, so that the groove plate 23 is stabilized at the specified height, and the excessive weight of the electrical device on the groove plate 23 is prevented from exceeding the supporting load of the cross support 14 and causing damage to the device.

[0033] As a further solution of the utility model, four brake wheels 16 are fixedly connected to the bottom of the groove plate 1, and a rubber membrane 5 is fixedly connected to one end of the two clamping blocks 6 close to the slide groove, and the width of the rubber membrane 5 is greater than the width of the slide groove. The provision of the brake wheels 16 facilitates the movement of the device. When it is necessary to lift the electrical device, the brake assembly of the brake wheels 16 can be stepped on, which helps to improve the stability of the electrical device when lifting. The rubber membrane 5 can isolate the threaded rod 7 from the electrical device to prevent foreign matter from falling on the threaded rod 7 and causing damage to the device.

[0034] The specific working method is: at the beginning, the electrical device is placed on the groove plate 2 3, the clamping assembly is started, the threaded rod 7 rotates to drive the adjacent clamping blocks 6 to move, so that the two clamping blocks 6 clamp the electrical device, the hydraulic rod 15 is stretched to drive the lifting assembly to lift, so that the groove plate 2 3 lifts the electrical device to a specified height, and when the electrical device reaches the specified position, the pin 11 is inserted into the locking hole 121 and the circular through hole 131 aligned with the locking hole 121, so that the force on both sides of the groove plate 2 3 is concentrated on the pin 11, so that the force on the cross support 14 is reduced, and the groove plate 2 3 can be made more stable at the specified height.
