Description

Technical Field

[0001] The utility model relates to a flexible wire releasing device for wires and cables in the production process of precast components. Background Art

[0002] Cast-in-situ concrete structures are widely used in industrial and civil buildings due to their high bearing capacity, good durability, strong integrity and good seismic performance. However, with the rapid development of China's economy, the construction of cast-in-situ concrete structures consumes a large amount of non-renewable resources. At the same time, a large amount of carbon emissions will be generated during the production process of concrete structures. In addition, due to the limitations of construction sites and construction time, a large amount of construction waste will be generated during the construction process of cast-in-situ concrete structures, which have caused serious damage to the environment. Therefore, developing green buildings and realizing the green development of the construction industry have become an inevitable trend in the future development of the construction industry. Developing precast concrete structures and realizing the prefabrication and assembly production of concrete structures are important ways to achieve the green development of the construction industry.

[0003] During the production process of precast components, the transportation of precast components needs to be completed under the traction of wires and cables. Existing wire releasing devices for wires and cables all complete the wire releasing through the cooperation of a wire reel and a fixed pulley. The wire reel is fixed on the track, and the fixed pulley is fixed on the sliding groove. The wire releasing is realized by the movement of the sliding groove on the track. However, by releasing the wire in this way, the tension of the wire is constant, and the force direction of the wire is also constant, resulting in a short service life of the wire.

[0004] Therefore, a flexible wire releasing device for wires and cables in the production process of precast components is needed, which can reduce the stress on the wires and extend the service life of the wires. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and provide a flexible wire releasing device for wires and cables in the production process of precast components, which can extend the service life of the wire releasing device by changing the force direction of the wire. The purpose of the utility model is achieved as follows:

[0006] A flexible wire releasing device for wires and cables in the production process of precast components includes a pulley set, a sliding plate, a rotating plate and a mounting plate. The pulley set is fixedly arranged on the central axis of the sliding plate. Both sides of the rotating plate are provided with sliding grooves. The length between the two sliding grooves is the same as the length of the sliding plate. The sliding plate can be clamped in the sliding groove and move in the sliding groove. The end of the rotating plate extending towards the sliding groove is provided with a limiting plate. Two springs are arranged on the limiting plate facing the sliding plate. A limit switch is also arranged on the limiting plate facing the sliding plate. The mounting plate is rotatably arranged under the rotating plate through a hinge member, and two hinge members are provided.

[0007] To enhance the wear resistance of the pulley and reduce the weight of the device, the pulley set is made of high-strength aluminum alloy, featuring good wear resistance and light weight. The diameter of the pulley is 120 mm, the width of the pulley groove is 50 mm, and the applicable cable diameter range is 6 to 12 mm.

[0008] To design the size of the skateboard to have sufficient stability and load-bearing area, and the clearance reduces the frictional resistance between the cable and the skateboard. The length of the skateboard is 1000 mm, the width is 150 mm, the thickness is 30 mm, and the clearance with the chute is not less than 0.5 mm.

[0009] The hardened chute wall increases the sliding stability, reduces wear, and improves the durability of the device. The chute extends into the rotating plate by at least 20 mm, the width of the chute matches the width of the skateboard, and the two side walls of the chute are hardened.

[0010] To better limit the movement of the skateboard, the thickness of the limit plate is 10 mm, the height is the same as the height of the skateboard, and the width is 100 mm.

[0011] Furthermore, the wire diameter of the spring is 5 mm, the coil diameter is 40 mm, the free length is 60 mm, and the compression ratio is 1:2.

[0012] To make the cable stop moving in time after the skateboard reaches the limit position, the limit switch is an electronic distance sensor that can monitor the position of the skateboard in real time.

[0013] Beneficial effects: Chutes matching the length of the skateboard are provided on both sides of the rotating plate, and the skateboard can move freely in the chutes. This structure allows the cable laying direction to be dynamically adjusted according to actual production requirements. The reasonable movement range of the skateboard is cooperatively controlled by the limit plate, spring, and limit switch. This sensitive feedback mechanism ensures the accurate stop of the skateboard at the two extreme positions, thus avoiding excessive stretching or uneven stress of the cable. Through the design of the spring and limit switch, the speed and length of the cable payout can be effectively controlled, and the flexible force application makes the cable payout process more controllable.

[0018] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] In this embodiment:

[0020] Please refer to Figures 1 - 3 , a flexible wire releasing device for cables in the production process of precast components, including a pulley set 4, a slide plate 3, a rotating plate 5 and a mounting plate 10. The pulley set 4 is fixedly arranged on the central axis of the slide plate 3. Chutes 8 are arranged on both sides of the rotating plate 5. The length between the two chutes 8 is the same as the length of the slide plate 3. The slide plate 3 can be clamped in the chutes 8 and move in the chutes 8. A limit plate 1 is arranged at the end of the rotating plate 5 extending in the direction of the chutes 8. Two springs 7 are arranged on the limit plate 1 facing the slide plate 3. A limit switch 2 is also arranged on the limit plate 1 facing the slide plate 3. A mounting plate 10 is rotatably arranged under the rotating plate 5 through a hinge 6. Two hinges 6 are provided.

[0021] The pulley set 4 is made of high-strength aluminum alloy, with good wear resistance and light weight. The diameter of the pulley is 120 mm, the width of the pulley groove is 50 mm, and the applicable cable 9 diameter range is 6 to 12 mm. The length of the slide plate 3 is 1000 mm, the width is 150 mm, and the thickness is 30 mm. The clearance with the chutes 8 is not less than 0.5 mm. The chutes 8 penetrate into the rotating plate 5 by at least 20 mm. The width of the chutes 8 matches the width of the slide plate 3. The two side walls of the chutes 8 are hardened. The thickness of the limit plate 1 is 10 mm, the height is the same as the height of the slide plate 3, and the width is 100 mm. The wire diameter of the spring 7 is 5 mm, the coil diameter is 40 mm, the free length is 60 mm, and the compression ratio is 1:2. The limit switch 2 is an electronic distance sensor and can monitor the position of the slide plate 3 in real time.

[0022] The following is the specific principle:

[0023] The cable 9 with tension is released from the cable reel of the cable 9, winds through the pulley block 4. After the cable 9 on the cable reel of the cable 9 is pulled out, the slide plate 3 slides back and forth on the rotating plate 5 under the action of the chute 8 and the spring 7, and is buffered by the spring 7. The force direction of the cable 9 and the direction of the elastic force change with the movement of the slide plate 3, and the force on the cable 9 also changes accordingly. The force on the cable 9 will not be too large, and the service life of the cable 9 is extended. In addition, the change in the force direction of the cable 9 can reduce the wear of the cable 9 and also extend the service life of the cable 9.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
