Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.

Example 1: a gripping hoist transport vehicle, see fig. 1-3, comprising a lever truck 1 and a gripper assembly 2. The clamp assembly 2 and the hanging end of the lever type transport vehicle 1 can be connected through a turn buckle 25, so that the effective height of the clamp assembly 2 can be conveniently adjusted as required. The turn-buckle 25 is preferably a malleable steel turn-buckle.

Referring to fig. 1, the lever type carrier vehicle 1 includes a lever 11 and a wheel 12 mounted on the lever 11 for forming a fulcrum, one end of the lever 11 forming a grip end at which a handle 111 is provided. The other end of the lever 11 forms a sling end 112.

The clamp assembly 2 comprises two lifting arms 221, two clamping parts 23 and an X-shaped revolute pair 222; the top ends of the two lifting arms 221 form a lifting point of the fixture assembly, the bottom ends of the two lifting arms 221 are respectively movably connected with the holding end of the X-shaped revolute pair 222, the two clamping parts 23 are respectively connected with the bottom revolute pair of the corresponding X-shaped revolute pair, and the rotating shafts of the two revolute pairs and the rotating shaft of the X-shaped revolute pair are parallel to each other. The rotation pair connection is adopted, and when the included angle of the X-shaped rotation pair is adjusted, the clamping surface of the clamping part 23 can still be attached to a heavy object. The "X" shaped revolute pair 222 is connected to the hitch end 112 of the lever truck 1 by a ball joint.

The ball joint connection can be formed in such a way: the lifting arm 221 includes at least one of a hoist rope and a hoist chain. Since the lifting rope and the lifting chain can be deformed, the lifting arm can form a spherical hinge connection at the moment.

The ball joint connection can also be formed in such a way: the lifting arm 221 is a connecting rod, the clamp assembly 2 further includes a universal joint 21, the top end of the connecting rod is movably connected with the universal joint 21, for example, hinged, and the other end of the universal joint 21 forms a lifting point of the clamp assembly.

Further, the "X" shaped rotating pair 222 includes two rod members connected to each other, and at least two rotating shaft mounting positions 2221 are provided on the rod members in the length direction, and the at least two rotating shaft mounting positions 2221 are used to form an adjustable torque.

In this embodiment, the rotating shaft mounting locations 2221 are through holes that are clearance-fit with the rotating shaft.

Further, a rubber pad 232 is bolted to the clamping portion 231 of the "X" shaped revolute pair 222.

Further, the clamp assembly further comprises a clamping part return spring 24, one end of the clamping part return spring 24 is connected with the X-shaped revolute pair, and the other end of the clamping part return spring is connected with the clamping part 231. The grip portion return spring 24 is a tension spring.

Snatch formula hoist and mount transport means needs two people cooperation operations to use, and one man operation grips end 111, one man operation anchor clamps subassembly 2. When the heavy object needs to be lifted, the clamping part 23 is pulled down, the holding end 111 tilts up, the clamping part 23 is pulled down to clamp the heavy object, another person presses down the holding end 111, and the lifting end 112 tilts up. The gravity of the heavy object is transmitted to the lifting arm 221 through the X-shaped revolute pair 222, and because the force-bearing directions of the two lifting arms 221 are inclined downward, the lifting arm 221 can pull the holding end of the X-shaped revolute pair to swing towards the central axis, and meanwhile, the clamping part of the X-shaped revolute pair can also swing towards the central axis, so that the self-locking clamping of the heavy object is realized. When the clamp assembly clamps the weight to be separated from the ground, the holding end can drive the weight to move. After the weight is moved to the destination and the weight is in contact with the ground, the lifting arm 221 is not pulled downwards obliquely any more, and the clamp assembly can be easily taken away. If the orientation of the weight needs to be adjusted, the weight cannot be supported by other supports in the process of adjusting the orientation of the weight, and the purpose of shifting the weight to steer can be achieved.

Due to the fact that the weights of the weights are different, the position of a rotating shaft of the X-shaped rotating pair can be adjusted according to needs, and self-locking clamping of the X-shaped rotating pair is achieved.

During manufacturing, the lever 11 is made of a steel tube with the outer diameter of 48mm and the wall thickness of 3.5mm, the steel tube a is 4m long, a long steel tube b with the length of 1.5m is vertically welded downwards at the position 1m from the outer end of one end of the steel tube a, an auxiliary reinforcing steel tube is welded at the position 0.5m and 0.5m from the upper welding point of the steel tube a, the lower end of the steel tube b is welded at the middle point of a wheel axle with the wheel distance of 1m and the wheel height of 0.6m, meanwhile, a long steel tube c with the length of 3m is welded at the welding point of the steel tube b and the wheel axle and the end point of the steel tube a, an angle of 60 degrees is formed between the steel tube c and the steel tube b, the. The tail end of the steel pipe a close to the welding point with the steel pipe b is welded with a hanging ring, and the steel pipe a is downwards and sequentially connected with a 360-degree universal joint, a turnbuckle rod, the hanging ring and a clamp. The clamp is formed by cutting an XX thick steel plate into two L shapes, five holes with the interval of 3cm and the aperture of 1cm are punched in the middle of the clamp, the clamp is overlapped in a crossed mode and fixed through holes of bolts, ear plates are welded on the side faces of the clamp, the bolts are used for connecting four corner punching steel plates with the angle of 4cm multiplied by 1cm through the shafts, the movable angle is 30 degrees, and the clamp arms and the gasket steel plates are connected through springs to tension the gasket. The rubber pads with the same size are fixed on the steel plate through screws, so that the materials are clamped in a protective mode, and friction force is increased.
