Description

Technical Field

[0001] The invention relates to a cable winding device, in particular to a fire-fighting cable winding device for buildings. Background Art

[0002] Buildings refer to artificially constructed assets and fall under the category of fixed assets, including two categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and conduct other social activities. What is different from buildings is structures. Structures refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges and chimneys.

[0003] The full name of RVS wire is copper core polyvinyl chloride insulated twisted connection soft wire, twisted multi-strand soft wire, referred to as twisted pair wire, commonly known as "flower wire". At this stage, this kind of wire is mostly used in fire protection systems, also called "fire protection wire". With the progress of society and the continuous improvement of people's living standards, the production methods of all walks of life have also undergone tremendous changes. Technological innovation is an important driving force for economic development and social progress. These changes have brought new challenges to the traditional wire-reeling method of the wire-reeling structure. The existing wire-reeling devices are all manually wound. Manual wire-reeling is not only inefficient, but the bobbin cannot adjust the wire-reeling radius of the wire-reeling device according to the length and weight of the wire. If the length of the wire is very long and the weight is very heavy, the weight will be very heavy after winding, which requires a lot of manual labor and is not easy to move. At the same time, the wire-reeling device after winding is also very large, which is not convenient for transfer and storage.

[0004] Therefore, we need to design a building fire-fighting cable winding device that can quickly reel in the wire, improve the reeling efficiency and reduce manual labor. Summary of the invention

[0040] The second belt assembly 93 is composed of two pulleys and a belt, one pulley is arranged on the tray 92, and the other pulley is arranged on the second rotating shaft 5, and the belt is wound between the two pulleys.

[0041] When people need to wind up the fire line, people can use this fire cable winding device for construction. First, people put the fire line in the first guide tube 2, then people pass the fire line head through the feeding wheel 7, and then people put the winding drum on the rotating mechanism 9. At this time, people wind the fire line head on the winding drum, and then people clamp the fire line head through the fastening mechanism 10. People start the motor 3. The rotation of the output shaft of the motor 3 will drive the first rotating shaft 4 to rotate, thereby driving the opposite gear set 6 to rotate, and then drive the fire line to move downward, thereby realizing the guiding function. At the same time, the rotation of the first rotating shaft 4 will drive the first belt assembly 8 to transmit, thereby driving the second rotating shaft 5 to rotate, and then driving the rotating mechanism 9 and the fastening mechanism 10 to rotate, and then drive the winding drum to rotate and wind up the fire line. When the winding drum is full of fire line, the winding drum cannot continue to wind up the fire line. At this time, people use a cutting knife to cut the fire line. When people still need to continue to wind up the remaining fire line, people repeat the above operation. When people have completed winding up the fire line, when people do not need to use it, people can turn off the motor 3.

[0042] People place the winding reel between the two trays 92, and then clamp the winding reel through the tray 92. At this time, people can wind the wire end around the winding reel. When the second rotating shaft 5 rotates, the rotation of the second rotating shaft 5 will drive the second belt assembly 93 to transmit, thereby driving the tray 92 to rotate, and then driving the winding reel to rotate to rewind the wire, thereby achieving the effect of rewinding the fire line, and people do not need to manually rewind the fire line.

[0043] When people wind the fire line around the winding drum, they push the clamping plate 102 outward, and the first torsion spring 103 is deformed. At this time, people put the fire line head between the two clamping plates 102. After people put the line head between the two clamping plates 102, they loosen the clamping plate 102. Since the first torsion spring 103 is reset, it will drive the clamping plate 102 to move inward, so that the clamping plate 102 clamps the fire line head to prevent the fire line head from slipping out during the process of winding the fire line, thereby failing to achieve the effect of winding the line. At the same time, when the tray 92 rotates, the rotation of the tray 92 will drive the first support column 101, the clamping plate 102 and the first torsion spring 103 to rotate, thereby assisting the winding drum to wind up the fire line.

[0044] When people place the winding bobbin between the two trays 92, the winding bobbin contacts the movable block 113, thereby driving the movable block 113 to move outward, and the first spring 114 is compressed. When people finish placing the winding bobbin between the two trays 92, the first spring 114 resets, so it drives the movable block 113 to move inward, so that the movable block 113 clamps the winding bobbin to prevent the winding bobbin from falling off during the winding process, thereby achieving the effect of clamping the winding bobbin more tightly.

[0045] When people pass the fire line end through the feeding wheel 7, people pass the fire line end through the second guide tube 124. When the second rotating shaft 5 rotates, the rotation of the second rotating shaft 5 will drive the third belt assembly 125 to transmit, thereby driving the missing gear 127 to rotate. Since the missing gear 127 is intermittently meshed with the first spur gear 126, it will drive the first spur gear 126 to rotate intermittently, thereby driving the twisted rod 122 to rotate, and then driving the second guide tube 124 to move left and right, and then driving the fire line to move left and right, avoiding uneven winding of the fire line when the winding drum is winding the fire line, thereby achieving the guiding function.

[0046] People can pull the movable rod 137 outward, and the second spring 138 is compressed, so that the movable rod 137 does not get stuck in the wedge block 135, and the second torsion spring 134 in the deformed state is reset, so it will drive the second baffle 132 to swing outward, and the first support frame 1 is opened. At this time, people can take out the wound fire line. When people still need to wind up the fire line, people put the fire line and the winding drum into the first support frame 1 again. After people have put out the fire line and the winding drum, people push the second baffle 132 inward, and the second torsion spring 134 is deformed. At this time, people release the movable rod 137. Since the second spring 138 is reset, it will drive the movable rod 137 to move inward, so that the movable rod 137 is stuck in the wedge block 135, and then the first support frame 1 is closed, and then the fire line winding work is started, thereby avoiding injuries to people during the fire line winding process.

[0047] When the movable rod 137 moves outward, the outward movement of the movable rod 137 will drive the second spur rack 147 to move outward. Since the second spur rack 147 and the first spur rack 146 are both meshed with the second spur gear 145, the second spur gear 145 will be driven to rotate, thereby driving the first spur rack 146 to move inward, and then driving the blade 142 to move inward, so that the blade 142 cuts the fire line, thereby achieving the effect of automatically cutting the fire line, which is more time-saving and labor-saving. When the movable rod 137 moves inward, the inward movement of the movable rod 137 will drive the second spur rack 147 to move inward and reset, thereby driving the second spur gear 145 to reverse, and then driving the first spur rack 146 to move outward and reset, and then driving the blade 142 to move outward and reset.

[0048] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
