[0002] The clamping of large frames needs to be carried out by using a hydraulic clamping device, and then the hydraulic clamping device is lifted by a travelling crane for movement, so as to realize the transfer of the frame. The current hydraulic clamping device is an external clamp or an internal clamp. For some special structure frames, only using the external clamp or the internal clamp leads to poor clamping stability, and the frame is prone to falling off, which has safety hazards. SUMMARY

[0003] In view of the above defects, the purpose of the present application is to provide a hydraulic hanging clamp mechanism, which aims to solve the technical problem of poor stability of the frame hanging clamp in the prior art.

[0004] To solve the above technical problems, the technical scheme of the present application is as follows:

[0005] A hydraulic hanging clamp device, comprising a U-shaped frame body, the U-shaped frame body comprising a first wing frame and a second wing frame, a connecting frame being fixedly connected between the first wing frame and the second wing frame, a hanging part being arranged on the outer side of the connecting frame, a first hydraulic cylinder being installed on the first wing frame, the extension end of the first hydraulic cylinder being opposite to the second wing frame, a second hydraulic cylinder being hung on the connecting frame through a rope, an inner cavity for accommodating the second hydraulic cylinder being arranged on the inner side of the connecting frame, and a traction device for winding the rope being installed on the connecting frame.

[0006] Among them, the connecting frame is provided with a first mounting hole, a rotating rod is rotatably installed in the first mounting hole, the first mounting hole and the inner cavity are connected through a first through hole, and two ropes are wound on the rotating rod.

[0007] Among them, the end of the rotating rod is provided with a connecting part for connecting with a rotating tool.

[0008] Among them, the connecting frame is fixedly connected with a connecting seat, the connecting seat is sleeved on the outside of the rotating rod, the connecting seat is provided with a first insertion hole, the rotating rod is provided with a second insertion hole corresponding to the first insertion hole, and a plug is inserted into the first insertion hole and the second insertion hole.

[0009] Among them, the connecting frame is provided with a second mounting hole, the second mounting hole is located between the first mounting hole and the inner cavity, the second mounting hole is connected with the first through hole, a connecting rod is inserted into the second mounting hole, the connecting rod is provided with a second through hole along the radial direction, and the rope penetrates through the second through hole.

[0010] Among them, one end of the connecting rod is provided with a limiting block, the connecting frame is provided with a sliding groove for accommodating the limiting block, the other end of the connecting rod is provided with a threaded segment, and a locking nut for pressing at the hole of the second mounting hole is screwed on the threaded segment.

[0011] Wherein, the outer end of the hanging portion is provided with a third through hole communicating with the inner cavity, and the liquid supply pipe of the second hydraulic cylinder passes through the third through hole.

[0012] Wherein, a cover cap is sleeved on the liquid supply pipe of the second hydraulic cylinder, and the cover cap is buckled on the port of the third through hole.

[0013] After adopting the above technical solution, the beneficial effects of the present invention are:

[0014] The hydraulic lifting clamp device of the present invention includes a 匚-shaped frame body, the 匚-shaped frame body includes a first wing frame and a second wing frame, a connecting frame is fixedly connected between the first wing frame and the second wing frame, a hanging portion is provided on the outer side of the connecting frame, a first hydraulic cylinder is installed on the first wing frame, the telescopic end of the first hydraulic cylinder is facing the second wing frame, a second hydraulic cylinder is suspended on the connecting frame by a rope, an inner cavity for accommodating the second hydraulic cylinder is provided on the inner side of the connecting frame, and a traction device for winding the rope is installed on the connecting frame. The requirements of stable, efficient and convenient workpiece clamping are achieved by synchronous or independent use of the external clamping function and the internal clamping function. By accommodating the second hydraulic cylinder in the inner cavity, the hydraulic lifting clamp device is more convenient to use, which greatly improves the efficiency of the clamping operation.

[0015] The connecting frame includes a first mounting hole, into which the rotating rod is rotatably mounted. The first mounting hole is connected to the inner cavity via a first through-hole. Two ropes are provided, and the two ropes are wound around the rotating rod. By driving the rotating rod to rotate forward or reverse, the two ropes can be synchronously wound and unwound, thereby achieving the raising and lowering of the second hydraulic cylinder.

[0016] A connecting base is fixedly connected to the connecting frame, and the connecting base is sleeved on the outside of the rotating rod. The connecting base is provided with a first socket, and the rotating rod is provided with a second socket corresponding to the first socket. A bolt is inserted into the first and second sockets. The rotating rod is fixed by inserting the bolt into the first and second sockets, thereby fixing the position of the second hydraulic cylinder and ensuring that the second hydraulic cylinder will not fall out after entering the inner cavity.

[0017] The connecting frame is provided with a second mounting hole, located between the first mounting hole and the inner cavity, and connected to the first through-hole. A connecting rod is inserted into the second mounting hole, and the connecting rod is provided with a second through-hole along a radial direction, through which the rope passes. The rope can freely pass through the second through-hole when winding and unwinding, and by pulling the connecting rod, the rope can be snapped into the second mounting hole, thereby securing the rope.

[0018] A stop block is provided at one end of the connecting rod, a slot is provided on the connecting frame to accommodate the stop block, and a threaded section is provided at the other end of the connecting rod, to which a locking nut is threaded for tightening against the opening of the second mounting hole. After the connecting rod is pulled until the stop block presses against the inner wall of the slot, the locking nut is rotated to tighten against the opening of the second mounting hole, thereby securing the connecting rod after it has been pulled.

[0019] Since the outer end of the hanging portion is provided with a third through hole connected to the inner cavity, the liquid supply pipe of the second hydraulic cylinder passes through the third through hole, thereby avoiding interference between the liquid supply pipe of the second hydraulic cylinder and other pipelines, and improving the rationality of the structural design.

[0020] Since the liquid supply pipe of the second hydraulic cylinder is covered with a cap, the cap is buckled on the end of the third through hole. The cap is used to buckle on the end of the third through hole, which can effectively prevent dust from entering the inner cavity through the third through hole, ensuring the cleanliness of the inner cavity.

[0021] In summary, the present invention solves the technical problem of poor stability of the frame hanging clamp in the prior art. The present invention can meet the simultaneous or independent use of external clamping function and internal clamping function, the clamping is stable and easy to use, and the efficiency of the clamping operation is greatly improved.
