detailed description

Example

The device will be further described below in conjunction with the accompanying drawings.

The utility model includes two mobile installation handcarts 1 symmetrically installed about the switch cabinet. The mobile installation handcarts are located on both sides of the switch cabinet body, and then use two fixed straps 2 to bind the switch cabinet, as shown in FIG. 9 . The switchgear fixing strap 2 is connected with the ring 20 of the bracket. The fixed strap 2 is provided with a manual tightening device 24 for binding the switchgear firmly. The manual tightening device is an existing common tightening part.

As shown in FIG. 8 , the mobile installation trolley includes a trolley 3 and a bracket 4 . As shown in Figure 5-7, the handcart is a gate-shaped structure, and the vertical metal round pipes 5 on the left and right sides of the gate. The top of the metal round pipe is welded with a flange 6, and the metal round pipe and the flange are vertically welded. A connecting rod 7 is housed in the metal circular tube, and a bottom metal plate 8 is connected below the connecting rod. The connecting rod is welded vertically to the bottom metal plate. The bottom metal plate bottom is equipped with guide wheels 10 for bearing and moving.

The top end of the connecting rod 7 is vertically welded with a top metal plate 12 . A pin 13 inserted into the round hole 14 of the flange is installed on the top metal plate for positioning the rotation angle of the connecting rod. The connecting rod can rotate freely in the metal tube and cannot move up and down. The connecting rod 7 drives the guide wheel 10 to rotate together, and the latch 13 can be inserted in the corresponding round hole of the flange 6 .

As shown in Fig. 5, two metal round tubes 5 are connected as a whole by two horizontal metal square tubes 15, one up and one down. The horizontal metal square tube above is equipped with a U-shaped handle 16 arranged horizontally, and the two ends of the U-shaped handle 16 are fixed at the junction of the metal circular tube and the horizontal metal square tube. Two vertical metal tubes 17 are connected between the upper and lower horizontal metal square tubes. A hydraulic jacking device 18 is installed on the horizontal metal square pipes between the metal vertical pipes 17 . The hydraulic jacking device 18 is fixed on the horizontal metal square tube below with screws and draw-in grooves, and is used to provide lifting force for the bracket 4 .

As shown in Fig. 1-3, the main body of the bracket 4 is also a gate-shaped frame structure. The left and right sides of the frame structure are vertical tubes, and each vertical tube is provided with two double guide wheel brackets 19 distributed up and down. When installed, the double guide wheel bracket faces the direction of the trolley. The double guide wheel bracket 19 is equipped with two U-shaped guide wheels arranged horizontally, and the two U-shaped guide wheels are jointly stuck on the metal round tube 5 of the trolley, so that the bracket can be combined with the trolley and can go up and down along the metal round tube. Move freely.

As shown in FIG. 3 , a horizontal circular ring 20 is respectively installed on the outer sides of the lower double guide wheel brackets 19 . The vertical square tubes on both sides are connected by three horizontal metal square tubes 15, one for each of the upper, middle and lower. Three support plates 21 for lifting the bottom of the switch cabinet are arranged in the lower ends of the vertical square tubes on both sides and in the middle of the horizontal metal square tubes below. As shown in Fig. 1, in order to improve the strength, a metal vertical tube 17 is connected between the lower horizontal metal square tube and the middle horizontal metal square tube in the middle. Two metal vertical square tubes 17 are connected between the middle and upper horizontal metal square tubes. A support 23 protruding toward the direction of the trolley is installed between the two metal vertical pipes 17 for connecting the top action point of the hydraulic jacking device 18 . Therefore, when the hydraulic jacking device 18 rises, the whole bracket 4 will rise thereupon.

The front side of the frame body of the bracket 4 is provided with a buffer layer, which is preferably a sponge, and is used to prevent bumping into the switch cabinet during transfer. The front side of the metal vertical tubes on both sides and the front side of the uppermost horizontal metal square tube are pasted with buffer sponges. As shown in Figure 9, the fixed strap 2 is a flat strap with metal hooks at both ends and a manual tightening device 24 in the middle.

When moving the metal switchgear, first use a special crowbar to raise the switchgear 10-20mm above the ground, extend the bottom pallets 21 of the two mobile installation handcarts into the bottom of the cabinet, close to the front and rear sides of the cabinet, and then place the The hooks at both ends of the two fixed straps are respectively hung on the rings on the outside of the double guide wheel bracket, and the fixed straps on both sides are tightened so that the handcart and the switch cabinet can be moved forward and backward as a whole. Operate the hydraulic jacking device 18 at the same time to make it rise, and the two ends of the metal switch cabinet are raised to a uniform height. According to the moving direction of the metal switch cabinet, adjust the direction of the guide wheel to move. In order to save effort, the connecting rod can be equipped with a hand wheel. After moving in place, release the hydraulic device slowly, and lower the metal switchgear slowly.

Example

As shown in Fig. 9, in terms of the transportation method for the metal switchgear, the embodiment adopted by the utility model is a mode in which two mobile and installation handcarts cooperate at the same time. When in use, use a crowbar to pry up both ends of the metal switch cabinet, move and install the handcart pallet and insert it into the front and rear or left and right sides of the metal switch cabinet, lift the metal switch cabinet, and then use two slings with metal hooks As a fixed strap, hang on the rings of the two mobile installation trolleys. Tighten the manual tightening device to connect the two installation handcarts as a whole.

In terms of the overall structure and materials of the handcart installation, the embodiment adopted by the utility model is that the overall frame is welded by circular and square steel pipes, which can bear a maximum total weight of 1800kg, and the main part is welded by 40mm*40mm square steel pipes. Supporting plate 21, the support that installs hydraulic jacking device 18 are that 8mm thickness steel plate welds and manufactures, and the liftable height is 80mm. The width of the bracket is 700mm, the height is 910mm, and the maximum size of the metal switchgear that can be loaded is 1200mm*2000mm. The bottom is equipped with rotatable guide wheels. Considering the weight and durability, the guide wheel made of nylon with a diameter of 180mm is selected, which can be turned and moved flexibly while ensuring sufficient weight and durability. In the substation, the cable trench is under the metal switchgear, so the mobile installation can be transported laterally across the cable trench.

In terms of lifting device, the utility model preferably adopts a manually operated hydraulic jacking device. Use the operating handle to continuously repeat the upward and downward movements to lift the jack. When lifting, two installation handcarts are required to lift at the same time, and the speed is kept consistent to ensure the smooth rise of the metal switchgear; when lowering, the handle of the hydraulic jacking device needs to be turned counterclockwise to make it fall slowly. This operation also requires two installation hands. The trolley operates at the same time to ensure the smooth lowering of the metal switchgear. The maximum weight that can be carried by one hydraulic jacking device is 1800kg, so the maximum weight that can be lifted when two installation handcarts are used at the same time is 3600kg.
