Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of reinforcing cage winding equipment, and particularly relates to an automatic winding and assembling device for prestressed reinforcing cages of electric poles and pipe piles. BACKGROUND
[0002] The prestressed reinforcing cage is a reinforcing mesh framework of a tapered concrete electric pole and a cylindrical concrete pipe pile, and the reinforcing cage needs to be tensioned to a certain tensioning force to be cold-drawn wire wound. In the existing device, the cold-drawn wire knotting detection and the tensioning of the reinforcing cage are first manually performed, and after the cold-drawn wire and the reinforcing cage are both detected, they are respectively transported to the corresponding winding equipment to complete the winding of the cold-drawn wire on the reinforcing cage. In the whole process, manual feeding and transporting are needed, which reduces the overall work efficiency.
[0003] At the same time, the common reinforcing cage tensioning in the industry uses an electric hoist to tension, one end of the reinforcing cage is fixed on a steel column, the other end is connected to the hook of the electric hoist, and the electric hoist is manually operated to tension the reinforcing cage to the tensioning force considered appropriate by the operator, and then the cold-drawn wire is wound. There is no tensioning force detection in the whole tensioning process, and it is completely judged by the experience of workers. The tensioning force is large or small in production, which leads to uneven and loose cold-drawn wire winding of the reinforcing cage, and the quality cannot be guaranteed. When the tensioning pressure of the electric hoist is too large, there is a safety hazard.
[0004] It can be seen that in the existing reinforcing cage tensioning process, there is no tensioning force detection, and it is completely judged by manual operation, which easily leads to large deviation of the tensioning force of each reinforcing cage of the same specification, affecting the product quality. After the reinforcing cage is tensioned, slight tensioning elongation will cause the tensioning force to rise rapidly, and it is difficult for manual operation to judge the tensioning force. If the tensioning force is too large, there will be a risk of damage to the reinforcing cage and the equipment, and a safety hazard to the personnel.
[0005] At present, in the process of winding the cold-drawn wire on the reinforcing cage, the traditional cold-drawn wire knotting condition is first detected manually. The detection of the cold-drawn wire knotting condition by manual operation not only has low detection efficiency and high labor cost, but also the whole bundle of cold-drawn wire is circular and is not convenient for detection. At the same time, the detection workers may miss the detection, leading to incomplete manual inspection, easy occurrence of manual injury risk, and affecting the detection quality. In addition, the existing cold-drawn wire has defects such as non-fixed knotting size and shape.
[0006] Therefore, the application urgently needs to develop an automatic winding and assembling device for prestressed reinforcing cages of electric poles and pipe piles. Through the cooperation of each module, the winding of the cold-drawn wire on the reinforcing cage is completed, the work efficiency is improved, and the defects of the reinforcing cage tensioning and the cold-drawn wire knotting detection are overcome.

[0050] Compared with the prior art, the present application has the following advantages:
[0051] 1) In use, first, the steel reinforcement cage is tensioned by the steel reinforcement cage tensioning machine to improve the tensioning quality of the product and improve work efficiency. Then, the cold-drawn wire is transported and the knotting condition is detected by the cold-drawn wire spiral rib knotting detection assembly. If the cold-drawn wire is not knotted, the qualified cold-drawn wire is directly wound on the steel reinforcement cage after tensioning.

[0078] Further, in some preferred embodiments, the cold-drawn wire loading assembly 3 includes:

[0080] Cold-drawn wire loading base 31, the cold-drawn wire loading 31 base is slidably installed on the sliding track 1;
[0081] A slip drive motor 32 is installed on the cold-drawn wire loading base 31, and a gear 33 is installed at the output end of the slip drive motor 32, and the gear 33 is in meshing transmission connection with the rack 30; the gear 33 is driven to rotate by the slip drive motor 32, and the gear 33 is driven to move on the meshing transmission rack 30, so as to realize the reciprocating movement of the cold-drawn wire loading assembly 3 along the sliding rail 1. The gear and rack transmission has simple and reliable implementation, and has good movement stability.
[0082] Further, in some preferred embodiments, the cold-drawn wire spiral rib knot detection assembly 2 comprises a base 21 arranged on the cold-drawn wire loading assembly 3, and a spiral rib automatic conveying mechanism 22 and a cold-drawn wire knot detection mechanism 23 arranged on the base 21, and the cold-drawn wire knot detection mechanism 23 is arranged at the output port of the spiral rib automatic conveying mechanism 22, so as to facilitate the input of the spiral rib output from the output port of the spiral rib automatic conveying mechanism 22 into the cold-drawn wire knot detection mechanism 23 for knot detection.
[0083] The spiral rib automatic conveying mechanism 22 comprises:
[0084] A rotating shaft 220 is vertically arranged on the base 21 and is in rotational connection with the base 21;
[0085] A spiral rib rotating disc 221 is arranged on the top of the rotating shaft 220 and is used for placing a whole bundle of spiral ribs;
[0086] A power member 222 is fixedly installed on the base 21, and the output end of the power member 222 is in transmission connection with the bottom of the rotating shaft 220, so as to drive the rotating shaft 220 to rotate, and then realize the rotation of the spiral rib rotating disc 221, realize the spiral horizontal conveying of the spiral rib, and correspondingly pull out the cold-drawn wire. The power member 222 in the embodiment is a motor.
[0087] The cold-drawn wire knot detection mechanism 23 comprises:
[0088] A base 230 is fixedly installed on the base 21; in the embodiment, the base 230 comprises a vertical support rod and a platform plate arranged on the top of the vertical support rod, and other components in the cold-drawn wire knot detection mechanism 23 are placed on the platform plate;
[0089] A limit switch 231 is fixedly installed on the upper surface of one end of the base 230, and the limit switch 231 is arranged at the output port of the spiral rib automatic conveying mechanism 22; the limit switch 231 has a self-resetting resilience, and the size of the self-resetting resilience can be selected and set according to actual needs; in the present application, the specific structure of the limit switch 231 is not limited, and a finished product sold on the market can be used as long as it can realize the function of limiting and locking.
[0090] A guide detection piece 232, the outer wall of the guide detection piece 232 is fixedly connected with the input end of the limit switch 231, and a through hole 2321 for the cold-drawn wire to pass through is arranged along the axial direction of the guide detection piece 232.
[0091] In use, the mechanical limit switch 231 is connected with the guide detection piece 232 in the cold-drawn wire knot detection mechanism 23, and the cold-drawn wire is inserted into the through hole 2321 of the guide detection piece 232 to detect whether the cold-drawn wire is knotted. If the cold-drawn wire is knotted, the knotted cold-drawn wire cannot pass through the through hole 2321 of the guide detection piece 232, so that the guide detection piece 232 is pressed to act on the limit switch 231, thereby limiting the conveying of the cold-drawn wire. When the knotted cold-drawn wire is unblocked, the guide detection piece 232 is no longer pressed, and the limit switch 231 has a certain self-resetting resilience and returns to the initial state.
[0092] In the present application, the cold-drawn wire spiral rib knot detection assembly 2 works as follows: firstly, knot detection is generally performed during the winding process, the power piece 222 drives the rotation of the rotating shaft 220, thereby realizing the rotation of the spiral rib rotating disc 221, achieving spiral horizontal conveying of the spiral rib, and correspondingly pulling out the cold-drawn wire without manual pulling, thereby reducing the labor intensity of workers and improving the work efficiency. Then, the cold-drawn wire is detected at one end, and knot detection is performed by the cold-drawn wire knot detection mechanism 23; if the cold-drawn wire is knotted, the knotted cold-drawn wire cannot pass through the through hole 2321 of the guide detection piece 232, so that the guide detection piece 232 is pressed to act on the limit switch 231, and correspondingly, a knot signal is transmitted to the control system of the whole machine device to automatically stop and alarm, reminding the operator to solve the problem of abnormal cold-drawn wire.
[0093] The cold-drawn wire spiral rib knot detection assembly 2 in the application realizes detection of the knot of the cold-drawn wire through the guiding detection piece 232 provided with the through hole 2321, can adapt to knot detection of cold-drawn wires of various specifications, and is applicable to different knot sizes and shapes of the cold-drawn wire and has strong adaptability. Once the cold-drawn wire is knotted, the limit switch 231 will immediately react, and the reaction is rapid and sensitive, so that the cold-drawn wire and the equipment are protected in time. Meanwhile, the cold-drawn wire spiral rib knot detection assembly 2 is arranged at the front end of the winding process, and does not affect the winding quality of the reinforcement cage. In addition, mechanical detection has high detection efficiency, no labor cost in the detection link, and no safety risk.
[0094] Specifically, the guiding detection piece 232 is a hollow steel column, and the inner diameter of the hollow steel column is 1.5 to 2.5 times the diameter of the cold-drawn wire. The shape of the steel column can be square, circular, polygonal, etc., which is not limited in the application. In the embodiment, the inner diameter of the hollow steel column is about 2 times the diameter of the cold-drawn wire. When the through hole 2321 in the hollow steel column is too small, the cold-drawn wire is slightly bent and deformed, and the limit switch 231 may perform a limit action, resulting in an incorrect judgment of the system. When the through hole 2321 in the hollow steel column is too large, the knotted cold-drawn wire can directly pass through the through hole 2321, resulting in a decrease in detection accuracy.
[0095] Specifically, the cold-drawn wire knot detection mechanism 23 can further include:
[0096] The limit switch connecting piece 233 has a first connecting end 2332 and a second connecting end 2333. The first connecting end 2332 is fixedly connected to the outer wall of the guiding detection piece 232, and the second connecting end 2333 is fixedly connected to the input end of the limit switch 231. Through the limit switch connecting piece 233, the mechanical connection between the limit switch 231 and the guiding detection piece 232 is realized, the production and manufacturing of parts are facilitated, and the production and processing cost is saved.
[0097] Specifically, the cold-drawn wire knot detection mechanism 23 can further include:
[0098] The guiding base 234 is fixedly installed on the upper surface of one end of the base 230 and is arranged between the guiding detection piece 232 and the output port of the spiral rib automatic conveying mechanism 22. In the embodiment, the guiding base 234 is in the shape of an inverted U.
[0099] The upper guide roller 235 is installed on the guiding base 234.
[0100] A lower guide roller 236 is installed on the guide base 234, arranged below the upper guide roller 235, and a gap is reserved between the lower guide roller 236 and the upper guide roller 235 for the passing of the cold-drawn wire, which plays a guiding role in the conveying of the cold-drawn wire.
[0101] Specifically, the cold-drawn wire knot detection mechanism 23 can further include:
[0102] An elastic member 237 has a first end 2371 and a second end 2372, the first end 2371 of the elastic member 237 is fixedly connected with the guide base 234, and the second end 2372 is fixedly connected with the middle part of the limit switch connecting piece 233. In this embodiment, the elastic member 237 is a tension spring, and a certain tension value is preset in the initial state, and the specific tension value can be designed by the person skilled in the art according to the actual situation. Preferably, the limit switch connecting piece 233 is a long strip plate, a through groove 2331 is formed along the length direction of the limit switch connecting piece 233, and the second end 2372 of the elastic member 237 is hooked at the through groove 2331 of the limit switch connecting piece, so as to realize the movable connection between the second end 2372 of the elastic member 237 and the limit switch connecting piece 233.
[0103] When the cold-drawn wire is normally conveyed, the cold-drawn wire inevitably has a contact friction force with the through hole 2321 of the guide detection member 232, and the hollow steel column will also bear a certain extrusion force. In order to prevent the limit switch 231 from malfunctioning due to the friction extrusion force, an elastic member 237 (spring) is fixedly installed in the direction opposite to the stress of the guide detection member 232, the first end 2371 of the elastic member 237 is fixedly connected with the guide base 234, and the second end 2372 is fixedly connected with the middle part of the limit switch connecting piece 233. In this way, the elastic member 237 can play a role of counterbalancing the friction force and avoiding malfunction on one hand, and the counteracting tension of the elastic member 237 can also help the limit switch 231 to reset after the limit switch 231 starts the limiting action and then the knotted cold-drawn wire is unblocked.
[0104] Specifically, the cold-drawn wire knot detection mechanism 23 can further include:
[0105] A guide piece 238 is fixedly installed on the upper surface of the base 230, is arranged opposite to the output side of the guide detection piece 232, and is provided with a through hole for the cold-drawn wire to pass through along the axial direction of the guide piece 238. The through hole of the guide piece 238 is substantially in the same straight line as the through hole 2321 of the guide detection piece 232, and plays a certain supporting and guiding role on the detected cold-drawn wire. In the embodiment, the through hole of the guide piece 238 is arranged opposite to the through hole 2321 of the guide detection piece 232, and the supporting and guiding effect is better.
[0106] Specifically, the cold-drawn wire spiral rib knot detection assembly 2 can further include:
