Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.
[0033] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a large pallet spreader for vehicles includes a back plate 1, a bottom plate, an operating handle 3, a pressing device, a locking device and a hoisting device.
[0034] The bottom plate is set horizontally, and the large pallet 01 to be hoisted can be placed on the bottom plate. The structure of the bottom plate is U-shaped, and each of the two U-shaped side legs of the bottom plate is preferably provided with a cushion block 15 . The material of each buffer block is preferably a nylon block, so as to reduce the wear on the surface of the pallet 01 to be hoisted, that is, the surface of the workpiece.
[0035] Further, a rectangular hole is preferably provided in the center of each cushion block, and an anti-slip pin 16 is provided in the rectangular...

The invention discloses a big-carriage lifting tool for vehicles. The big-carriage lifting tool comprises a backboard, a base plate, a compression device, a locking device and a lifting device, wherein the backboard is vertically arranged on the base plate and is fixedly connected with the base plate; the compression device is arranged in the middle of the backboard and comprises a first support arm, a second support arm, a supporting cushion block, a clamping block, a central pin, a supporting shaft and an extension spring; and the locking device comprises a supporting block and a spring cotter. By virtue of the structure, the relative position of a suspension ring on a supporting suspension table is regulated when a big carriage is lifted, the originally horizontally placed big carriage is still lifted in the horizontal direction together with the lifting tool under the action of gravity, and the attitude of the big carriage does not need to be manually regulated, so that the mounting efficiencies of the big carriage and a machine body are improved; and when the big carriage is lifted and transported, the big carriage is always in a horizontal attitude under the action of gravity, and meanwhile, the upper and lower surfaces of the big carriage are commonly clamped by virtue of a compression block and the backboard, so that the safety and the stability in the lifting process are guaranteed, and the rapid lifting, transportation and mounting of the big carriage are realized.
Description
technical field [0001] The invention relates to a mechanical device for hoisting and installing large pallets on the job site, which belongs to the technical field of mechanical fixtures, in particular to a large pallet spreader for vehicles. Background technique [0002] The front axle of the vehicle is a device that transmits the force in all directions between the frame and the front wheels and the resulting bending moment and torque. Before installing the front axle, it is necessary to install a large trailer. The installation of the large trailer will have a significant impact on the front axle. to the role of support and fixation. At present, there is no special spreader for this kind of large pallet on the market. When lifting without the help of a spreader, the large pallet is only manually moved and installed. The labor intensity of the workers is high and the operation is unsafe; use ordinary spreaders to lift When the large pallet is used, it is impossible to mai...
