Detailed ways

A simple equipment hoist for electric equipment maintenance, the key point is that it includes a car body and a hoisting device, the hoisting device is fixed on the front end of the car body, and the car body includes a support plate 1 and two groups symmetrically arranged on both sides of the support plate Wheels 2, each group of wheels 2 is two in front and one behind. The hoisting device includes a support column 3, a boom 4 and a fixed pulley 5. The support column 3 is vertically arranged on the front end of the support plate 1, and the boom 4 is arranged horizontally and horizontally. On the upper end of the support column 3, one end of the boom 4 is fixed to the support column 3, and the other end cantilever extends away from the vehicle body. The fixed pulley 5 is fixed on the lower side of the cantilever end of the boom 4. The middle part of one side of 5 is fixedly provided with motor 6, and the output end of motor 6 is provided with reel 7, and reel 7 outer circumference surface is wound with traction rope, and one end of traction rope is fixed with reel 7 outer circumference, and the other end passes fixed pulley Stretch out after 5 and be equipped with suspension hook 8.

Specific embodiments, as shown in Figure 1 and Figure 2, the rear end of the support plate 1 in the car body is provided with a trolley frame, the trolley frame includes two support bars that are inclined to the rear side of the car body and are parallel to each other and connect the two The hand push rod 13 on the upper end of the support rod, the operator holds the hand push rod 13 to push the hoist and move to the construction site, and the left and right sides of the support plate 1 are respectively provided with two ground support devices and two wheels on the corresponding side 2, the ground support devices on the left and right sides are arranged symmetrically one by one. The front end of the support plate 1 is also provided with a ground support device at the position outside the support column 3. The ground support device includes a guide hole block 9, a guide post 10 and a fixed On the supporting floor 11 at the lower end of the guide column 10, the lower end surface of one side of the guide hole block 9 is fixed to the upper end surface of the support plate 1 of the vehicle body, and the other side is suspended in the air, and the middle part of the suspended side of the guide hole block 9 is provided with a guide hole. The guide post 10 is located in the guide hole, the lower end of the guide post 10 is fixed to the upper end surface of the support floor 11, the guide post 10 descends along the guide hole, the support floor 11 gradually contacts with the ground and supports the vehicle body, as the guide post 10 descends, the vehicle The car body gradually leaves the ground. This setting can make the pressure transmitted to the ground through the guide column 10 and the support floor 11 when the hoist is working, so that the car body is more stable and is less prone to rollover. The wheels 2 of the car body are not subject to pressure and extend The service life of the wheel 2 is extended, the motor is connected with a remote control device, and the operator manipulates the remote control device to drive the motor to rotate, so that the hook moves down from the lower end of the fixed pulley to the height of the equipment, and then the hook hooks the equipment, and then manipulates the remote control device to drive The motor reverses, and the hook lifts the equipment up to complete the hoisting work.
