Description

Technical Field

[0001] The present application relates to the technical field of ball valves, and in particular to a hoisting device for installing a ball valve. Background Art

[0002] A ball valve is defined as a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-shaped ball core and the metal valve seat with welded cemented carbide, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the media in the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are classified into pneumatic ball valves, electric ball valves, and manual ball valves.

[0003] Nowadays, residential buildings or large shopping malls have an increasing demand for water, and it is necessary to install larger-diameter sewer pipes to discharge the generated wastewater. In some underground pipes with larger diameters, larger ball valves need to be installed. However, larger ball valves are heavy, which makes it inconvenient for construction workers to install them, resulting in poor installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a hoisting device for installing a ball valve, so as to solve the problems raised in the above background technology.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] The cam is fixedly mounted on the outside of the vehicle frame, and the cam is connected to the control wheel shaft through the upper and lower ends of the vehicle frame to contact with the driver's seat of the vehicle frame.

[0007] Preferably, two storage boxes are fixedly mounted on the upper surface of the base plate, and a door handle is fixedly connected to the upper surface of each storage box.

[0008] Preferably, a load block is fixedly connected to the upper surface of the base plate, and three first reflective stickers are adhered to the outer surface of the L-shaped bent rod.

[0009] Preferably, four support plates are fixedly connected to the upper surface of the base plate, and outer surfaces of the four support plates are commonly fixedly connected to the outer surface of the electric lifting rod.

[0010] Preferably, a work display light is provided on the upper surface of the support rod, anti-slip sleeves are sleeved on the outer surfaces of the two handles, and a switch button is provided on the front of the support rod.

[0011] Preferably, a second reflective tape is bonded to the outer surface of the support rod.

[0012] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0013] First, the lifting equipment can be moved to the position where the ball valve needs to be installed by using a steerable and movable small flatbed cart composed of a base plate, a first directional wheel, a first bearing, a first rotating rod, a second directional wheel and a support plate, thereby making it convenient to move the lifting equipment to the position where the ball valve needs to be installed.

[0014] Secondly, the ball valve can be lifted and lowered, and its position can be changed by lifting the electric lifting rod and rotating the L-shaped bent rod in the damping bearing, solving the problem of laborious installation of the ball valve by manpower. The ball valve can be lifted and lowered, making it easier to install, saving human resources and improving installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The first bearing 3, the first rotating rod 4 and the pulley mechanism 24 form a joystick that can change the pulley device to change the moving direction of the base plate 1, and the support rod 5 and the handle 6 form a handlebar. The support rod 5 can be rotated by holding the handle 6. The lifting of the electric lifting rod 7 can control the height of the rotating hook 15, and controlling its height is convenient for lifting the ball valve on the ground. The controller 11 controls the lifting of the electric lifting rod 7, and the damping bearing 9 changes the angle of the L-shaped bent rod 10 to improve the installation efficiency. The circular hole 13 on the fixed plate 12, the circular ring 14 and the rotating hook 15 form a hook fixing component, which is convenient for hanging the ball valve.

[0025] In this embodiment, two storage boxes 16 are fixedly installed on the upper surface of the base plate 1, and a door handle 17 is fixedly connected to the upper surface of each storage box 16; a load block 18 is fixedly connected to the upper surface of the base plate 1, and three first reflective stickers 19 are adhered to the outer surface of the L-shaped bent rod 10; specifically, installation tools are placed in the storage box 16 to improve the efficiency of installing the ball valve. The door of the storage box 16 is opened by holding the door handle 17, which is convenient for opening and closing the door. The load block 18 increases the weight of the base plate 1. When the weight of the lifted ball valve is large, the base plate 1 will be tilted. When working at night, the first reflective sticker 19 reflects light, and the presence of the equipment can be discovered;

[0026] In this embodiment, four support plates 20 are fixedly connected to the upper surface of the base plate 1, and the outer surfaces of the four support plates 20 are fixedly connected to the outer surface of the electric lifting rod 7; the upper surface of the support rod 5 is provided with a work display light 21, the outer surfaces of the two handles 6 are both sleeved with anti-slip sleeves 22, and the front of the support rod 5 is provided with a switch button 23; the outer surface of the support rod 5 is adhered with a second reflective tape 25; specifically, the support plate 20 fixes the electric lifting rod 7 installed on the base plate 1 to increase its stability. When the electric lifting rod 7 is raised or lowered, the work display light 21 lights up, so that personnel know that the equipment is in operation. Pressing the switch button 23 controls the lifting and lowering of the electric lifting rod 7, which is convenient for controlling it. When working at night, the second reflective tape 25 reflects light, which is conducive to discovering the lifting equipment.

[0027] Working principle: When using this kind of lifting equipment for installing a ball valve, the user first rotates the support rod 5 to change the direction of the pulley in the pulley mechanism 24, and then pushes the equipment to move the lifting equipment to the appropriate position. The height of the rotating hook 15 is adjusted by raising and lowering the electric lifting rod 7, and the ball valve is wrapped and fixed by the cooperation of the rotating hook 15 and the hanging rope. Then the electric lifting rod 7 rises to lift the ball valve, and then pushes the support rod 5 to move the equipment. After moving to the appropriate position, the angle of the ball valve on the rotating hook 15 is adjusted by rotating the L-shaped bent rod 10 on the damping bearing 9, and it is installed after it is lowered to the appropriate position in conjunction with the lowering of the electric lifting rod 7.
