Abstract
The invention discloses a hoisting mechanism for a translational type crane. The hoisting machine comprises a main shaft. An end cover is connected to one end of the main shaft; a speed reducer is connected to the other end of the main shaft; a winding drum is arranged on the outer side of the main shaft; a steel wire rope is wound on the winding drum; a rope pressing device is tightly butted with the outer side of the steel wire rope; the rope pressing device comprises a roller, a connecting rod and a spring; the connecting rod is movably connected with each of the roller and the spring. According to the invention, by mounting the rope pressing device on one side of the winding drum, the lifting rope is orderly wound so as to solve the problem of phenomena of winding, loosening and the like of the lifting rope in the operating process, ensure uniformity of stress of the lifting rope and improving operating efficiency while prolonging the service life of the lifting rope.
Description
Technical field
The present invention relates to marine machinery manufacturing technology field, be specifically related to a kind of lifting mechanism of the parallel-moving type hoisting crane with rope press device.
Background technology
Lifting rope wind2 is requisite equipment on hoisting crane, although the reel of existing lifting rope wind2 is provided with thread groove, its make lifting rope orderly be wound on reel, but lifting rope still appears in the situation of the winding of continuous several times between adjacent two threads groove or the situation such as Yin Lali is too small or the excessive lifting rope caused is slack and undisciplined in winding process, and unordered winding can make lifting rope discontinuity in winding process, increase the friction force between lifting rope, greatly shorten the service life of lifting rope, reduce production efficiency.
Summary of the invention
Goal of the invention: the object of the invention is to solve deficiency of the prior art, provides a kind of lifting mechanism extending the parallel-moving type hoisting crane in lifting rope service life.
Technical scheme: the lifting mechanism of a kind of parallel-moving type hoisting crane of the present invention, comprise main shaft, one end of described main shaft is connected with end cap, the other end of described main shaft is connected with reductor, the outside of described main shaft is provided with reel, and on described reel, volume has steel rope, and the outside of described steel rope has pushed against rope press device, described rope press device comprises roller, pipe link and spring and forms, and described pipe link is flexibly connected with roller and spring respectively.
As preferably, between described end cap and main shaft, be also provided with bearing and lubricating cup.
As preferably, below described end cap, be also provided with support.
As preferably, the side of described reel is also provided with pressing plate.
As preferably, described reductor is also connected with motor.
Beneficial effect: the present invention is by installing rope press device in the side of reel, make the winding that lifting rope is orderly, thus solve that lifting rope is in operation wound around, the generation of the phenomenon such as slack and undisciplined, ensure that lifting rope uniform force, while the service life extending lifting rope, improve the efficiency of operation.
Accompanying drawing explanation
Fig. 1 is lifting mechanism structural representation of the present invention.
Fig. 2 is rope press device constructional drawing of the present invention.
Detailed description of the invention
The lifting mechanism of a kind of parallel-moving type hoisting crane as depicted in figs. 1 and 2, comprise main shaft 2, one end of main shaft 2 is connected with end cap 1, the other end of main shaft 2 is connected with reductor 4, the outside of main shaft 2 is provided with reel 3, on reel 3, volume has steel rope, the outside of steel rope has pushed against rope press device 5, rope press device 5 comprises roller 7, pipe link 8 and spring 9 are formed, pipe link 8 is flexibly connected with roller 7 and spring 9 respectively, wherein also be provided with bearing and lubricating cup between end cap 1 and main shaft 2, support 6 is also provided with below end cap, the side of reel 3 is also provided with pressing plate 10, reductor 4 is also connected with motor.
Principle of design of the present invention is exactly the arranged outside one Ge Yasheng mechanism at original lifting rope reel, and this Ya Sheng mechanism compresses whole lifting rope side completely, and the pressure of whole Ya Sheng mechanism is controlled by spring.When lifting rope pull-up rolls out, spring is upspring, and steel rope rolls out; When lifting rope stops rolling out, the tension force due to spring makes Ya Sheng mechanism being pressed on wire rope roll tightly, thus prevents slack and undisciplined phenomenon.
The present invention is by installing rope press device in the side of reel, make the winding that lifting rope is orderly, thus solve that lifting rope is in operation wound around, the generation of the phenomenon such as slack and undisciplined, ensure that lifting rope uniform force, while the service life extending lifting rope, improve the efficiency of operation.
