Abstract
The utility model relates to a lifting trolley which comprises a trolley frame, a transverse lifting bracket and a lifting rope and further comprises a ratchet-and-pawl device, wherein the trolley frame comprises a base, a vertical bar and universal wheels; the lower part of the vertical bar is fixed with the upper part of the base; the universal wheels are arranged at the lower part of the base; the upper part of the vertical bar is perpendicularly fixed with the transverse lifting bracket; fixed pulleys are arranged at both ends of the transverse lifting bracket; the ratchet-and-pawl device is arranged in the middle of the vertical bar; a handle is arranged at one end of the ratchet shaft of the ratchet-and-pawl device; one end of the lifting rope is connected with the ratchet shaft of the ratchet-and-pawl device; a hook is arranged at the other end of the lifting rope; and the lifting rope bypasses the two fixed pulleys on the transverse lifting bracket. According to the lifting trolley, a ratchet is rotated by rotating the handle so as to lift a workpiece, reliable locking is realized through a pawl, and especially, a screw-and-nut fine-adjusting device is arranged, so that an operator can automatically measure the height of the workpiece by eye during mounting, and the whole lifting process is safe, reliable, convenient and fast.
Description
Technical field
The utility model relates to a kind of travelling jack.
Background technology
The stator outlet box of motor is heavier, at present, and when motor is installed the stator outlet box; The cranes laggard luggages of slinging that use are joined more, because outlet box and motor mounting hole site be in the side, the crane man author can't judge the position of mounting hole; Lean on assembler author to command and could accomplish entirely, whole assembling is consuming time longer, and has certain potential safety hazard; In addition, each assembling needs a crane to cooperate, and has taken ample resources.
Summary of the invention
The purpose of the utility model is to overcome above defective, and a kind of safe and reliable, easy to operate travelling jack is provided.
The technical scheme of the utility model is: vehicle frame, horizontal hoisting bracket, click apparatus, lifting rope, and said vehicle frame comprises base, vertical rod, cardan wheel, said vertical rod bottom and base top are fixed; Said cardan wheel is located at the base bottom; Said vertical rod top and horizontal hoisting bracket vertical fixing, said horizontal hoisting bracket two ends are equipped with fixed pulley, and click apparatus is located at the vertical rod middle part; End at the click apparatus ratchet shaft is provided with handle; Said lifting rope one end is connected with the ratchet shaft of click apparatus, and the other end is provided with hook, and lifting rope is walked around two fixed pulleys on the horizontal hoisting bracket.
Easy to operate for the worker, said vertical rod is provided with handrail.
For the ease of the guiding of lifting rope, be provided with vertical passing channel at the two ends of horizontal hoisting bracket, between two fixed pulleys, be provided with horizontal passing channel.
Height for the ease of accuracy control workpiece in the installation process; Below click apparatus, be provided with the bolt and nut micromatic setting; Said bolt and nut micromatic setting screw rod top and click apparatus bottom are fixed, and the nut of said bolt and nut micromatic setting is fixed on the vertical rod middle part.
The braking of transfer car(buggy) for ease, the cardan wheel of said vehicle frame below is provided with stop motion mechanism.
The beneficial effect of the utility model is when work, can drive ratchet through turning handle to rotate the lifting that realizes workpiece; And through the reliable locking of ratchet realization; Be provided with the bolt and nut micromatic setting especially; The worker can estimate the workpiece height voluntarily during installation, and whole handling process is safe and reliable, convenient and swift.
