Abstract
Description
Technical Field
[0001] This utility model relates to a handling gripper based on an electric forklift, belonging to the technical field of handling auxiliary equipment. Background Technology
[0002] Electric forklifts are commonly used material handling equipment in warehousing and logistics, primarily using their forks to lift and move goods. However, in actual operation, for some goods with hanging holes, hook slots, or that need to be hooked and secured from both sides, such as metal frames, wooden pallet assemblies, and large pipes, traditional forks can only lift them from the bottom, which has the following shortcomings: Poor cargo stability: Without a dedicated hook structure, cargo is prone to shifting, shaking, or even slipping during handling, posing a safety hazard. Poor adaptability: It cannot adjust the hook spacing according to the size of the goods. When dealing with goods of different lengths, different auxiliary tools need to be changed, resulting in low work efficiency. Insufficient installation stability: Existing auxiliary grippers are mostly connected to the forks by a simple sleeve method, lacking a reliable fixing structure. During operation, they are prone to relative displacement with the forks, posing a safety hazard.
[0003] To address the aforementioned issues, there is an urgent need for a handling gripper that can be stably installed on the forks of electric forklifts, has adjustable hook spacing, and offers high safety. Utility Model Content
[0004] This invention provides a handling gripper based on an electric forklift, solving the problems mentioned in the background art.
[0005] This utility model relates to a handling gripper based on an electric forklift, including a handling tube installed on the forks of the electric forklift. The handling tube has a telescopic tube that can be extended and retracted from both ends to adjust its length. The telescopic tube has handling hooks at both ends. Two inserts are fixed at the bottom of the handling tube and are respectively fitted onto the front ends of the two forks. The front ends of the inserts are closed. The rear ends of the top of the inserts are connected to a protective chain. The protective chain is equipped with turnbuckles. The other end of the protective chain is connected to an L-shaped protective hook plate that cooperates with the longitudinal plate of the rack.
[0006] As a preferred embodiment, lifting rings are fixed to the side walls at both ends of the conveying tube, and the lifting rings are connected to a fixing chain. A pin is fixed to the other end of the fixing chain. Each end of the conveying tube has an adjustment hole (I), and the telescopic tube has multiple adjustment holes (II) along its length that mate with the adjustment holes (I). The pins connected by the fixing chain allow the telescopic tube to be adjusted to the target length. These pins are then inserted into the adjustment holes (I) of the conveying tube and (II) of the telescopic tube, achieving a secure positioning of the telescopic tube and the conveying tube. This prevents the telescopic tube from sliding during cargo handling, ensuring a stable hook spacing. Simultaneously, the fixing chain prevents the pins from being lost, improving the ease of use and operational safety of the components.
[0007] As a preferred embodiment, a tension handle is fixed to the outer end of the telescopic tube, and a hanging ring is movably connected to the top of the handling hook. A fixing seat is hinged to the top of the hanging ring and fixed to the bottom of the outer end of the telescopic tube. The tension handle provides an easy point of force for the operator to pull the telescopic tube to adjust its length, reducing operational intensity. The hinged design of the hanging ring and the fixing seat allows the handling hook to be flexibly adjusted at different angles, adapting to different positions and angles of the goods. This avoids problems such as the goods not being securely hooked or unable to be hooked due to unsuitable hook angles, thus improving operational flexibility.
[0008] As a preferred embodiment, a reinforcing plate is fixed to the top center of the conveying pipe, extending along its length. Multiple reinforcing ribs are fixed to both sides of the reinforcing plate, and the bottom of each reinforcing rib is welded to the conveying pipe. The connection between the reinforcing plate and the conveying pipe, along with the reinforcing ribs, can distribute the tensile force borne by the conveying pipe during cargo handling, preventing deformation or breakage due to excessive stress, extending the service life of the gripper, and improving the overall structural load-bearing capacity.
[0009] As a preferred embodiment, a second reinforcing rib is fixed to the outside of the transport tube, and the bottom of the second reinforcing rib is welded and fixed to the insert sleeve.
[0010] As a preferred embodiment, the sleeve includes a top plate and a bottom plate. The front end of the top plate has a bent edge that is bent downwards and fixed to the bottom plate. Side plates are welded to the front and rear sides of both the top plate and the bent edge. The bottom of the side plates is welded to the bottom plate. A wear-resistant block is welded to the rear side of the bent edge, and the upper rear side of the wear-resistant block has a slot that mates with the front end of the fork. The top plate, bottom plate, side plates, and bent edge are welded to form a closed sleeve, which is convenient for manufacturing. The wear-resistant block can reduce the direct friction between the fork and the bent edge of the sleeve, prevent the sleeve from wearing out too quickly, and extend the service life of the sleeve.
[0011] As a preferred embodiment, a support plate is provided at the top front end of the base plate. The front end of the support plate has a support recess for supporting the wear-resistant block. The front end of the support plate is welded and fixed to the bent edge. A support ramp is provided on the rear top side of the support plate, which mates with the bottom of the fork's front end. The support recess of the support plate effectively supports the wear-resistant block, preventing it from falling off under stress. The support ramp fits snugly against the bottom of the fork's front end, further enhancing the fit between the fork and the sleeve, preventing the fork from wobbling within the sleeve, and improving installation stability.
[0012] This utility model has the following beneficial effects: High installation stability: By fitting the sleeve with the fork, combined with the fixing of the protective chain, turnbuckle and protective hook plate, the grab and electric forklift are double fixed, avoiding relative displacement during operation; Adjustable spacing: The telescopic tube can extend and retract along the conveying tube, which can adapt to the hooking needs of goods of different lengths and has strong versatility; High safety: The enclosed front end of the plug, the tightened protective chain, and the stable hook structure effectively prevent goods from slipping and the gripper from loosening, reducing safety risks.
