Technical Field
[0001] The utility model relates to the field of mechanical engineering, in particular to a mechanical engineering hoisting claw hand. Background Art
[0002] In industrial production, it is often necessary to move and lift heavy workpieces, machinery and equipment or raw materials. These workpieces may have different shapes, sizes and weights. Traditional manual lifting methods are inefficient and pose safety risks. Therefore, mechanical engineering lifting claws are needed to complete these tasks. Lifting claws are widely used in factory production lines, ports, freight logistics centers, construction sites and other places. They can be used to lift and move heavy machinery and equipment, steel, concrete components, container boxes and other large objects.
[0003] The structure of a lifting claw used in mechanical engineering usually includes the following key parts: a support structure, which is the main frame of the lifting claw and provides stable support for the entire equipment. It is usually made of high-strength materials and is designed to withstand the weight of the hoisted objects and the forces generated during the lifting process; a clamping device, which is the core part of the lifting claw and is used to fix and clamp the hoisted objects. The clamping device can be a mechanical clamp, a magnetic clamp or a vacuum suction cup, etc. The specific type is determined according to the material, shape and surface characteristics of the hoisted object.
[0004] The structure of the mechanical engineering lifting claws currently on the market is relatively complex and cannot be adjusted according to the size of the object to be clamped. In addition, the clamping method of most claws on the market is to rotate and close around a point, which will cause the claw to be in a tilted state when clamping, and there will be a safety hazard of unstable clamping. Moreover, most of the mechanical engineering lifting claws currently need to be manually controlled to clamp when in use, which reduces work efficiency. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a mechanical engineering lifting claw hand to solve the technical problems of traditional claw hands such as complex structure, unstable contact, inability to adjust the clamping size and the need for manual control of clamping.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanical engineering lifting claw, including a lifting block, a rope hole is provided at the top of the lifting block, the bottom ends on both sides of the lifting block are rotatably connected to two first rotating shafts, and the outer wall of each first rotating shaft is staggered with two limit rods, the two limit rods at the same end of the same side are parallelly aligned, and each limit rod is slidably penetrated by a corresponding second rotating shaft, multiple second rotating shafts are rotatably connected to corresponding clamping jaws, and two second rotating shafts are provided on the outer walls of both sides of each clamping jaw, the outer walls of the two groups of clamping jaws are provided with fixed blocks, and the fixed blocks are located below the lifting block, two sliding grooves are provided inside the fixed block, and the clamping jaws are slidably engaged in the corresponding sliding grooves.
[0007] By adopting the above technical solution, the traction steel cable is passed through the cable hole to fix the device, driving the lifting block upward. With the cooperation of multiple limit rods and fixed blocks, the clamping claw moves horizontally inward along the slide groove to complete the horizontal clamping of the device.
[0008] The utility model is further configured such that each of the limit rods is provided with a plurality of positioning holes, and each second rotating shaft is movably penetrated by a fixing pin, and an outer wall of the fixing pin is in sliding contact with a positioning hole in the corresponding limit rod.
[0009] By adopting the above technical solution, the relative positions of the second rotating shaft and the limiting rod are adjusted according to the size of the object to be clamped, and the fixing pin is then inserted to complete the fixing of the second rotating shaft and the limiting rod.
[0010] The utility model is further configured as follows: a first limit block is slidably inserted into both sides of the bottom end of the lifting block, and a second limit block is arranged on the outer wall of the first limit block, the inner wall of the lifting block of the second limit block is connected to a limit spring, a limit shaft is arranged in the middle of the top of the fixed block, and a first embedded oblique block is installed on the top of the limit shaft, the outer wall of the limit shaft is sleeved with a second embedded oblique block, the second embedded oblique block is located below the first embedded oblique block, and the bottom surface of the first embedded oblique block is movably fitted with the top surface of the second embedded oblique block, and in the initial state, the relatively inward ends of the two first limit blocks are inserted into the gap between the first embedded oblique block and the second embedded oblique block.
[0011] The first limit block continues to descend, and finally, with the cooperation of the limiting spring, it slides in contact with the first embedded oblique block and passes through the first embedded oblique block, completing the opening and fixing of the clamping jaws.
[0012] In summary, the utility model mainly has the following beneficial effects:
[0013] The utility model fixes the device through the cable hole and the steel cable, adjusts the relative position of the second rotating shaft and the limit rod according to the size of the object to be clamped, and inserts the fixing pin to complete the fixing of the second rotating shaft and the limit rod after confirmation. In the initial state, the first embedded inclined block and the first limit block are fixed and limited, so that the clamping claw device is in an open state during the movement. At this time, the device is lowered, the fixed block contacts the object to be clamped, the fixed block stops descending, the limit shaft at the top is raised relative to the device, and the first limit block is relatively lowered to the setting of the limit spring. After closing and sliding contact with the second embedded oblique block, it passes over the second embedded oblique block, and then stretches the lifting block upward, and the first limit block drives the second embedded oblique block upward to fit with the first embedded oblique block and continue to rise. Under the action of the second embedded oblique block and the limit spring, the first limit block slides in contact with the second embedded oblique block and the first embedded oblique block and passes over the second embedded oblique block and the first embedded oblique block, and the fixed block releases the direct connection with the lifting block.
