Detailed Description

The technical scheme of the utility model is explained in detail in the following with the accompanying drawings:

referring to fig. 1, the movable suction cup type carrying equipment comprises a base 1, a vertical column 4, a first rotating arm 8, a second rotating arm 9, an electric balancer 6, a steel wire rope 7, a vacuum pump 2, a gas pipeline 5, a suction cup assembly 11 and an electric cabinet 3.

The lower end of the upright post 4 is fixedly connected with the base 1. The vacuum pump 2 and the electric cabinet 3 are arranged on the upright post 4.

As shown in fig. 1 and 2, one end of the first rotating arm 8 is rotatably connected to the upper end of the column 4 through a bearing, and the other end is rotatably connected to one end of the second rotating arm 9 through a bearing, and the first rotating arm 8 and the second rotating arm 9 constitute a double-joint mechanical arm. It should be noted that the two rotational joints are not provided with a driving device such as a motor, and the motion of the mechanical arm is realized by manual pulling.

As shown in fig. 1, 2, 5 and 6, the first rotating arm 8 and the second rotating arm 9 are further provided with a plurality of guide wheels 12 which are in contact fit with the steel wire rope 7. One end of the steel wire rope 7 is connected with the electric balancer 6 arranged on the first rotating arm 8, and the other end of the steel wire rope is connected with the sucker component 11 arranged below the other end of the second rotating arm 9 in a hanging manner after being guided by the guide wheel 12.

The electric balancer 6 is a well-established equipment module that can be connected to a wire rope 7 or a chain, and is generally used to lift a heavy object. The electric balancer 6 can provide a lifting force balanced with the pulling force applied to the steel wire rope 7, so that the weight lifted by the steel wire rope 7 is in a nearly suspended state, and the weight can be lifted or lowered by providing an external force which is far smaller than the gravity of the weight and is upward or downward.

In the utility model, the electric balancer 6 is pulled by the steel wire rope 7 to be the sucker assembly 11, and the sucker assembly 11 sucks goods.

As shown in figure 3, the sucker component 11 comprises a control handle 11-1, a connecting body 11-2 and soft suckers 11-3, wherein two groups of soft suckers 11-3 are arranged at the bottom of the connecting body 11-2. The air suction end of the vacuum pump 2 is communicated with the soft sucker 11-3 through an air pipeline 5, and the air pipeline 5 is arranged along the upright post 4, the first rotating arm 8 and the second rotating arm 9. The control handle 11-1 is electrically connected with the electric cabinet 3, and is provided with a control button for controlling the action of the electromagnetic valve arranged on the gas pipeline 5 through the electric cabinet 3. When the electromagnetic valve is opened, the negative pressure generated by the vacuum pump 2 is transmitted to the soft sucker 11-3, and the goods can be sucked. After the electromagnetic valve is closed, no negative pressure exists at the position of the soft sucking disc 11-3, and the sucked goods can be released.

Further, the gas pipeline 5 is communicated with the soft suction cup 11-3 through a channel inside the connecting body 11-2. And a pressure gauge 11-4 communicated with the channel is also arranged on the connecting body 11-2.

In this embodiment, the control handle 11-1 is vertically installed on the top of the connecting body 11-2, and the upper end of the control handle 11-1 is connected with the steel wire rope 7. The connecting cable between the control handle 11-1 and the electric cabinet 3 is laid along the second rotating arm 9, the first rotating arm 8 and the upright 4. The operator only needs to hold the control handle 11-1 with one hand, so that the sucker assembly 11 can be moved, and the suction and release of the sucker can be controlled.

An alternative sub-optimal solution is also provided here: the top of the connecting body is directly connected with the steel wire rope, and the control handle is arranged independently of the connecting body. Although the design can also realize the control of the sucker assembly, the operator needs two hands to operate, one hand is responsible for moving the connecting body and the soft sucker, and the other hand holds the control handle to control the negative pressure.

Further, this equipment still includes the extension spring (not seen in the figure), the upper end of extension spring is connected with the other end of second rotor 9, and the lower extreme is connected with sucking disc subassembly 11 for upwards pulling sucking disc subassembly 11. When the tension spring is added, the load of the electric balancer 6 is reduced, and the electric balancer 6 can quickly lift the load by applying a small lifting force to the operator.

Further, in order to prevent the wire rope 7 and the tension spring from clamping the hands of the operator, the equipment further comprises a telescopic protective cover 10. The upper end of the telescopic protective cover 10 is connected with the other end of the second rotating arm 9, and the lower end of the telescopic protective cover is connected with the sucker component 11. The steel wire rope 7 and the tension spring penetrate through the telescopic protective cover 10.

When moving the goods, the operator moves the sucker component 11 in a pulling mode to enable the soft sucker 11-3 to be tightly attached to the surface of the goods, and the mechanical arm and the electric balancer 6 move along with the sucker component 11 in the process. Then, the solenoid valve is controlled to be opened, the goods are sucked up by negative pressure, and then the suction cup assembly 11 is manually lifted, and the heavy goods are lifted up by means of the electric balancer 6. Then, promote sucking disc subassembly 11, move the goods to the target location, again pull down sucking disc subassembly 11, electric balancer 6 can be automatic slowly release wire rope 7, and the goods slowly falls to the target location, closes the solenoid valve at last, removes the negative pressure, releases the goods.

Further, as shown in fig. 1 and 4, the base 1 in the equipment has two functions, namely, supporting the whole device, and being matched with a forklift to realize the overall rapid movement of the equipment.

In this embodiment, the base 1 includes a disk 1-1 and a bridge-shaped support 1-3 fixedly installed on the top of the disk 1-1.

And a chamfer is arranged at the outer edge of the disc 1-1. The disc 1-1 is provided with a square wheel hole 1-2 matched with a front wheel of a forklift.

The support 1-3 comprises a top plate and a left side vertical plate and a right side vertical plate, the top plate is positioned above the disc 1-1 and is horizontally arranged, the upper end of each side vertical plate is connected with the top plate, and the lower end of each side vertical plate is connected with the disc 1-1. And a reinforcing rib plate is arranged on the outer side of the side vertical plate. The top plate, the side vertical plates and the discs 1-1 form a through groove for inserting the forklift arm.

As shown in fig. 7, when the whole device needs to be moved, the second rotating arm 9 is folded, and then the forklift arm of the forklift is inserted into the through groove, and the front wheel of the forklift is embedded into the wheel hole 1-2 and lands. Then, the forklift starts to lift, the forklift arm lifts the whole equipment through the supports 1-3, and then the equipment can be moved through the forklift.

The reason why the support 1-3 is used to form the slot in cooperation with the disk 1-1, rather than directly opening the slot at the bottom of the disk 1-1, is that: in order to prevent the equipment from falling down, the diameter of the disk 1-1 cannot be designed to be too small, if the slot is formed at the bottom of the disk 1-1, the thickness of the disk 1-1 is inevitably increased, and finally, the volume, the weight, the material cost and the center of gravity of the disk 1-1 are too large. Therefore, the utility model adopts the scheme that the disc 1-1 directly falls to the ground and the bracket 1-3 is used for constructing the slot above the disc 1-1, so that the disc 1-1 can be thinner, the material is saved, and the gravity center is also reduced.
