Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a cable winding mechanism for a building crane. Background Art

[0002] A crane is a kind of handling tool often used on construction sites or in the manufacturing industry. It can move heavy objects, thus greatly improving work efficiency.

[0003] At present, the overall mass of the crane cable is heavy, and the winding mechanism is generally connected to the external frame through an axis. Apart from this, there is no other structure that can provide auxiliary support. Therefore, during long-term work, the load-bearing capacity of the axis is large, and it is prone to poor rotation or even the risk of breakage. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a cable winding mechanism for a construction crane, so as to solve the problem that the existing winding mechanism proposed in the above background technology has no auxiliary support structure and is prone to poor rotation and breakage risks at the connection during use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable winding mechanism for a construction crane, comprising a mounting frame with through holes on both sides of the bottom; a winding shaft, which is rotatably arranged inside the mounting frame, and one end of the winding shaft is fixed with a shaft support component that passes through the interior of the mounting frame and is rotatably connected thereto, and is connected through the through hole, and one end of the support component passes through the interior of the mounting frame and is rollingly connected to the winding shaft, thereby supporting the winding shaft, reducing the weight of the output shaft part of the driving motor under the direct action of the winding shaft, ensuring normal winding during use, and being able to achieve normal rolling of the winding shaft by rolling, avoiding the phenomenon of poor winding caused by large friction; a driving motor, whose output end is fixedly connected to the other end of the winding shaft, thereby driving the winding shaft to rotate through the driving motor and achieving the purpose of winding.

[0006] Preferably, the supporting assembly includes a limiting stud passing through the through hole, and a rolling wheel is fixed to the end face of the limiting stud on the inner side of the mounting frame. The rolling wheel rolls with the end face of the winding shaft, thereby supporting the winding shaft and being able to rotate with the rotation of the winding shaft. A limiting member is also provided in the area where the limiting stud is located in the outer direction of the mounting frame. The limiting member is in contact with or separated from the outside of the mounting frame, that is, it will not cause extrusion to the mounting frame, thereby ensuring the normal rotation of the limiting stud, and its main purpose is to limit the rolling wheel.

[0007] Preferably, the limiting member includes a limiting nut screwed into the limiting stud, and a plurality of holes are also opened on the limiting stud, and a limiting pin is inserted into at least one of the holes. The limiting pin abuts against the limiting nut, thereby limiting the position of the limiting nut and preventing the limiting nut from abutting against the outer surface of the mounting frame and causing the limiting stud to be locked.

[0008] Preferably, a deformation groove is formed at one end of the limit pin, and the limit pin expands toward the inner wall of the hole through the deformation groove, thereby achieving a tight connection between the limit pin and the hole to avoid separation.

[0009] Preferably, a limiting portion is fixed to the end surface of the rolling wheel away from the limiting stud, and the limiting portion abuts against the inner side surface of the winding shaft, thereby ensuring contact between the rolling wheel and the winding shaft.

[0010] Preferably, a lubrication channel is opened at the top of the mounting frame, the top area of ​​the lubrication channel is a vertical portion, and the bottom area is an inclined portion extending obliquely toward the end face of the winding shaft. During use, the lubricating oil is injected from the lubrication channel, and then the lubricating oil flows into the inclined portion through the vertical portion, thereby achieving lubrication of the contact surface of the mounting frame and the winding shaft.

[0011] Preferably, a sealing plug is inserted into the top opening of the vertical portion of the lubrication flow channel for daily protection, and a ball is arranged in the inclined portion of the lubrication flow channel, which rolls with the end face of the winding shaft to achieve a small amount of uniform discharge of lubrication oil.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The designed support component can not only support the winding shaft, but also realize the auxiliary rolling of the winding shaft, thereby achieving the two-in-one effect of support and transmission, avoiding the risk of poor rotation or breakage caused by the winding shaft being supported alone. At the same time, the support component is easy to install, has high practicality and flexibility in use, and improves the shortcomings of the existing structure in use.
