Description

TECHNICAL FIELD

[0001] The utility model belongs to material handling auxiliary equipment field, especially relates to a clamp for bagged material handling. BACKGROUND

[0002] Fertilizer is usually packaged in bags, and it is often necessary to transport the fertilizer for the purpose of storage and transportation, and the fertilizer is usually transported in batches, the total quantity is large, and the weight of each bag is heavy. Relying on pure manpower to transport is inefficient and can cause great harm to the laborers' bodies. Therefore, in the current transport work, pneumatic power-assisted mechanical grippers are often used to assist laborers in transporting.

[0003] The main function of the pneumatic power-assisted mechanical gripper is to clamp and place the material and lift it, and the clamp and the power-assisted arm are important components for realizing the main function. The clamp can clamp and place the material, and the power-assisted arm can assist the lifting of the clamp. The cooperation of the clamp and the power-assisted arm realizes the transport assistance and saves labor. Since the equipment is not fully automated, the operator needs to hold the control frame installed on the clamp to move and control the clamp during the operation. Therefore, the structure of the control frame directly affects the controllability of the equipment.

[0004] The existing control frame mainly has two types, one is a short control frame directly fixed vertically on the side of the clamp, and the other is a long control frame hinged to the side of the clamp. The short control frame can move the clamp very directly and is suitable for transporting low-height materials, but when the clamp needs to transport high-height materials, the operator needs to hold the short control frame by lifting his hand, which is very inconvenient. The long control frame is easy to reach for the operator when the clamp transports high-height materials due to its length, but its length becomes an inconvenient factor when transporting low-height materials. The two types of control frames have different application scenarios, but in actual use, factors such as loading height, stacking height, and height position change will affect the control requirement. The existing clamp usually only has one type of control frame, which is difficult to meet the multiple transport requirements in actual use and will affect the transport efficiency. If another set of equipment is added, it will increase the cost of the equipment and occupy a large space, which is not conducive to the transport of materials. SUMMARY
