Description
Technical Field
[0001] This utility model relates to the field of lifting clamp technology, specifically a rail lifting clamp that is easy to fix. Background Technology
[0002] Rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock, bear the enormous pressure of the wheels, and transmit it to the sleepers. Rails must provide the wheels with a continuous, smooth, and least resistant rolling surface. In electrified railways or automatic block sections, rails can also serve as track circuits. Cranes are needed to transport rails, and rails also need to be hoisted. However, rails may move during hoisting, so hoisting clamps are needed to fix the rails in place. However, improper use of clamps may cause wear on the rail surface. Therefore, those skilled in the art have provided a rail hoisting clamp that is easy to fix, in order to solve the problems mentioned in the background art. Summary of the Invention
[0003] The purpose of this invention is to provide a rail hoisting clamp that is easy to fix, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A rail hoisting clamp for easy fixation includes a fixed top plate, a distance adjustment structure, and a clamping structure. The distance adjustment structure is provided at the lower end of the bottom surface of the fixed top plate, and the clamping structure is provided at the lower end of the distance adjustment structure. A first fixing plate is provided on the left side of the bottom surface of the fixed top plate, and a second fixing plate is provided on the right side of the bottom surface of the fixed top plate. The positions of the first fixing plate and the second fixing plate are symmetrical. A hoisting handle is provided in the middle of the upper surface of the fixed top plate. The distance adjustment structure includes: a connecting plate, a square through groove, a long threaded rod, a first moving block, a first limiting slider, a second moving block, a second limiting slider, and a fastening threaded assembly. A connecting plate is provided in the middle between the corresponding sides of the first fixing plate and the second fixing plate.
[0006] Preferably, a square through groove is provided through the middle of the upper surface of the connecting plate, and a long threaded rod is provided between the corresponding side surfaces of the fixing plate one and the fixing plate two and at the lower end of the connecting plate.
[0007] Preferably, a first movable block and a second movable block are respectively provided through the surface of the long threaded rod. A first limiting slider is provided on the upper surface of the first movable block. The upper end of the first limiting slider penetrates the interior of the square through groove and is located at the upper end of the square through groove.
[0008] Preferably, the upper surface of the movable block two is provided with a limiting slider two, the upper end of the limiting slider two penetrates the interior of the square through groove, and several sets of fastening threaded parts are provided on the surface of the long threaded rod at the upper end of the square through groove.
[0009] Preferably, the clamping structure includes: a receiving plate, a limiting slide groove, a first fixing block, a second fixing block, a first stop block, a moving clamping plate, a slider, a second stop block, a servo motor, a screw, and a protective layer. The bottom surfaces of both the first moving block and the second moving block are provided with receiving plates.
[0010] Preferably, a limiting groove is provided in the middle of the bottom surface of the receiving plate, a fixing block one is provided on the rear side of the bottom surface of the receiving plate, and a fixing block two is provided on the front side of the bottom surface of the receiving plate.
[0011] Preferably, a stop block is provided at the lower end of the rear surface of the second fixing block, a servo motor is provided at the upper end of the front surface of the second fixing block, and a screw is provided in the middle of the rear surface of the servo motor.
[0012] Preferably, the end of the screw away from the servo motor passes through the second fixing block and is connected to the front surface of the first fixing block. A movable clamp is provided between the corresponding side surfaces of the first fixing block and the second fixing block and on the surface of the screw.
[0013] Preferably, a slider is provided in the middle of the upper surface of the movable clamping plate, and the slider is located inside the limiting groove in the middle of the bottom surface of the receiving plate.
[0014] Preferably, a second stop is provided at the lower end of the front surface of the movable clamping plate, and a protective layer is provided on the corresponding side surface of the movable clamping plate and the second fixed block.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The distance between moving block one and moving block two is adjusted according to the length of the rail. The limiting slider one at the upper end of moving block one and the limiting slider two at the upper end of moving block two maintain the stability of moving block one and moving block two on the surface of the long threaded rod. Then, moving block one and moving block two are fixed to the surface of the long threaded rod by fastening threaded fittings on the surface of the long threaded rod. The rail is placed between the corresponding surfaces of the two sets of moving clamps and the fixed block two. The function of stop blocks one and two is to prevent the rail from sliding off the moving clamps and the fixed block two. The corresponding surfaces on one side detach from each other. A servo motor drives the screw to rotate. The rotation of the screw causes the movable clamping plate on the screw surface to move under the restriction of the slider, thereby clamping and fixing the rail between the corresponding surfaces of the movable clamping plate and the fixed block. The protective layer prevents the surface of the rail from being worn by clamping. Finally, the rail is lifted and transported by a hoist. This solves the problem mentioned above. However, the rail may move during hoisting, so hoisting jigs are needed to fix the rail. However, improper use of jigs may cause wear on the surface of the rail. Attached Figure Description

[0026] The working principle of this utility model is as follows:
[0027] This utility model relates to a rail hoisting clamp that is easy to fix. In specific use, the whole structure is first moved to a suitable location. The distance between moving block one and moving block two is adjusted according to the length of the rail. The function of the limiting slider one at the upper end of moving block one and the limiting slider two at the upper end of moving block two is to maintain the stability of moving block one and moving block two on the surface of the long threaded rod. Then, moving block one and moving block two are fixed to the surface of the long threaded rod by the fastening threaded fitting on the surface of the long threaded rod. The rail is placed between the two sets of moving clamps and the corresponding side surfaces of fixed block two. The function of stop block one and stop block two is to prevent the rail from falling off between the corresponding side surfaces of moving clamps and fixed block two. The servo motor drives the screw to rotate. The rotation of the screw causes the moving clamps on the surface of the screw to move on the surface of the screw under the restriction of the sliders, thereby clamping and fixing the rail between the corresponding side surfaces of moving clamps and fixed block two. The function of the protective layer is to prevent the surface of the rail from being worn by clamping. Finally, the rail is lifted and transported by the hoisting handle.
