Description

Technical Field

[0001] The invention belongs to the technical field of cable storage, and in particular relates to a pulley cable taking-up device. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are used to transmit electricity or information from one place to another. They are widely used in the production and preparation of the machinery industry.

[0003] Since cables are generally long and heavy, conventional winding equipment is large in size and has too many usage restrictions. In addition, cables that are too long will also take up a large storage space. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the invention

[0004] The object of the present invention is to provide a pulley cable take-up device to solve the problem of excessive usage restrictions in the existing devices for taking up and releasing cables mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pulley wire-winding device, comprising a mounting plate, which is generally in an annular shape and has a through hole thereon, through which the cable passes to realize wire-winding and wire-releasing operations; an inner support frame, which is two concentric annular steel frames above and below; a sliding member, which is mounted on the outside of the inner support frame, and the top of the sliding member is fixedly arranged at the bottom of the mounting plate, so as to fix the mounting plate, the inner support frame and the sliding member; a fixed pulley block, which is mounted at an equal angle at the bottom of the mounting plate, and the fixed pulley block and the sliding member are staggered and spaced to avoid that the two are arranged at the same position and affect the subsequent normal wire-winding and wire-releasing operations; a movable pulley block, which is mounted on the sliding member and performs vertical lifting and lowering movements along the sliding member; a cable is inserted between the fixed pulley block and the movable pulley block, the bottom end of the cable falls freely and is electrically connected to an external device, and the top end passes through a hole in the mounting plate and is connected to a lifting device.

[0006] As a preferred technical solution in the present invention, the sliding member includes a slide rail fixed to the outside of the inner support frame, and the top end of the slide rail is welded and fixed to the mounting plate; it also includes a slide table slidably arranged on the slide rail, and the movable pulley group is installed on the slide table, so as to achieve the purpose of vertical lifting and sliding of the movable pulley group on the slide rail through the slide table.

[0007] As a preferred technical solution in the present invention, the movable pulley group includes a movable frame fixed on the slide, and a movable pulley arranged in the movable frame. A movable shaft passing through the movable pulley is fixed in the middle of the movable frame, so that the movable pulley can rotate normally in the movable frame.

[0008] As a preferred technical solution in the present invention, a counterweight block is also installed at the bottom end of the movable frame. The shape of the counterweight block includes a cylinder. The counterweight block does not contact the slide rail to avoid movement interference. Through the setting of the counterweight block, the deadweight of the movable pulley and the movable frame can be increased, and the cable can be pulled down so that the cable is in a state of being straightened obliquely, thereby avoiding the stress of the bending shape of the cable itself causing multiple movable pulley groups to be uneven and affecting the later line collection.

[0009] As a preferred technical solution in the present invention, the fixed pulley group includes a fixed frame fixed to the bottom end of the mounting plate by bolts, and a fixed pulley fixed in the fixed frame by an axis, and the fixed pulley rotates around the axis. The number of the fixed pulley groups is equal to the number of the movable pulley groups, and the two are staggered at equal angles. During the line winding, the top of the cable is pulled by the lifting equipment, and the cable will pass through the fixed pulley, completing the first labor-saving lifting. When the cable is continuously pulled, the movable pulley group will be driven to lift on the slide rail through the slide, and at the same time drive the movable pulley to rotate, completing the second labor-saving lifting.

[0010] As a preferred technical solution in the present invention, the diameters of the two annular steel frames constituting the inner support frame are equal, thereby ensuring that the slide rail is arranged in a vertical state.

[0011] As a preferred technical solution in the present invention, stop blocks are fixedly provided at both ends of the slide rail, which are not marked in the figure. The stop blocks abut against the slide table to limit the slide table and avoid falling off.

[0012] As a preferred technical solution in the present invention, the cable passing through the fixed frame and the movable pulley is wavy, and the diameter of the cable is less than or equal to the groove width of the fixed frame and the movable pulley itself.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the cable is lifted and wound up by means of a pulley group, which not only reduces the power demand for the power equipment, but also enables the long cables to be bent and stored, occupies a small space, and is convenient for use in various industrial equipment. At the same time, the device of the present invention has a simple structure, is easy to process, and has good practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 The present invention provides a technical solution: a pulley wire taking-up device, comprising

[0027] The mounting plate 100 is in the shape of a ring as a whole and has a through hole thereon, through which the cable 500 passes to realize the operation of winding and releasing the cable;

[0028] The inner support frame 101 is two concentric annular steel frames;

[0029] The sliding member is installed outside the inner support frame 101, and the top end of the sliding member is fixed to the bottom end of the mounting plate 100, so as to fix the mounting plate 100, the inner support frame 101 and the sliding member;

[0030] The fixed pulley block 200 is installed at an equal angle at the bottom of the mounting plate 100. The fixed pulley block 200 and the sliding member are arranged at an offset interval to avoid the two being arranged at the same position to affect the subsequent normal retracting and releasing operation;

[0031] The movable pulley block 300 is mounted on the sliding member and performs vertical lifting motion along the sliding member;

[0032] A cable 500 is inserted between the fixed pulley block 200 and the movable pulley block 300. The bottom end of the cable 500 falls freely and is electrically connected to an external device, while the top end passes through a hole on the mounting plate 100 and is connected to a lifting device.

[0033] In this embodiment, the sliding member includes a slide rail 400 fixed to the outside of the inner support frame 101, and the top of the slide rail 400 is welded and fixed to the mounting plate 100; it also includes a slide table 401 slidably set on the slide rail 400, and the movable pulley group 300 is installed on the slide table 401, so as to achieve the purpose of vertical lifting and sliding of the movable pulley group 300 on the slide rail 400 through the slide table 401.

[0034] In this embodiment, the movable pulley group 300 includes a movable frame 302 fixed on the slide 401, and a movable pulley 301 arranged in the movable frame 302. A movable shaft passing through the movable pulley 301 is fixed in the middle of the movable frame 302, so that the movable pulley 301 can rotate normally in the movable frame 302.

[0035] In this embodiment, a counterweight block 303 is also installed at the bottom end of the movable frame 302. The shape of the counterweight block 303 includes a cylinder. The counterweight block 303 does not contact the slide rail 400 to avoid movement interference. Through the setting of the counterweight block 303, the dead weight of the movable pulley 301 and the movable frame 302 can be increased, and the cable 500 can be pulled down, so that the cable 500 is in a state of being straightened obliquely, avoiding the stress of the bending shape of the cable 500 itself causing the multiple movable pulley groups 300 to be uneven and affecting the later line collection.

During line winding, the top of the cable 500 is pulled by a lifting device, and the cable 500 will pass through the fixed pulley 202, completing the first labor-saving lifting. When the cable 500 is continuously pulled, the movable pulley block 300 will be driven to be lifted on the slide rail 400 as a whole through the slide 401, and at the same time, the movable pulley 301 will be driven to rotate, completing the second labor-saving lifting.

[0038] In this embodiment, stop blocks are fixedly provided at both ends of the slide rail 400, which are not marked in the figure. The stop blocks abut against the slide table 401 to limit the slide table 401 and prevent it from falling off.

[0039] In this embodiment, the cable 500 passing through the fixed frame 201 and the movable pulley 301 is wavy, and the diameter of the cable 500 is less than or equal to the groove width of the fixed frame 201 and the movable pulley 301 itself.
