Description

Technical Field

[0001] The invention relates to the technical field of prefabricated beam reinforcement welding, and in particular to a reinforcement welding device used in a prefabricated beam field. Background Art

[0002] In the actual precast beam yard, a large number of precast beams need to be prefabricated and formed, and the steel cage needs to be tied and then cast. The precast beam manufacturing involves the installation of prestressed tensioning cables. It is necessary to place corrugated pipes in the steel cage of the precast beam in advance and then pour concrete to facilitate the subsequent threading of the bundled steel cables. The corrugated pipes located above the steel cage are usually placed in a parabolic shape. The positioning bars bearing the corrugated pipes are welded in advance at the web of the steel cage to ensure that the corrugated pipes are parabolic after placement. After the corrugated pipes are placed, they are welded to the positioning bars through horseshoe tendons to limit the corrugated pipes. The current precast beam yard uses steel bar welding Most devices require manual holding of horseshoe tendons for welding, which has poor precision. The horseshoe tendons are skewed during welding and the fit with the horseshoe tendons is poor, which easily affects the positioning stability of the bellows. Because there is a gap between the positioning ribs that support the bellows, the tension of the bellows after the positioning ribs directly affects the parabolic accuracy of the bellows. The gaps are prone to sinking, affecting the subsequent prestressed pulling effect. Traditional manual operation and measurement are cumbersome, and it is not convenient to automatically prompt the staff to calibrate parameters as the welding position moves. The manual operation to adjust the bellows tensioning effect is not accurate, affecting the horseshoe tendon welding accuracy. Summary of the invention

The use of the horseshoe tendon welding part 1 can facilitate the staff to press the horseshoe tendon without manual support. At the same time, the structure is handheld and operated, which is flexible and convenient. In conjunction with the bellows positioning part 2, the structure can ensure that the horseshoe tendon can be placed at the interval of the threaded protrusions of the bellows. The horseshoe tendon is inserted by utilizing the concave characteristics of the interval of the threaded protrusions of the bellows to ensure the limiting stability of the horseshoe tendon on the bellows and improve the stability of the bellows after welding. The structure uses two in-place micro switches 202 to ensure the accuracy of the in-place detection, which is convenient for the staff to observe and more practical. After the horseshoe tendon is inserted into the bellows, the horseshoe tendon mounting frame 101 is pressed downward. When the horseshoe tendon is placed at the interval of the threaded protrusions of the bellows, the threaded protrusions of the bellows will squeeze the two pressing sheets 203, thereby squeezing the in-place micro switch 202 and controlling the horseshoe tendon in-place indicator light 302 to light up.

[0040] In the embodiment of the present disclosure, the tendon vertical positioning member 3 includes: a vertical positioning shell 301, a vertical micro switch 3011, a tendon in-place indicator light 302, an anti-mistouch spring 303, a tendon vertical indicator light 304 and a pressing column 305, and the vertical positioning shell 301 is fixedly installed with a vertical micro switch 3011; the vertical positioning shell 301 is fixedly installed on the top of the tendon mounting frame 101; two tendon in-place indicator lights 302 are fixedly installed on the top of the tendon mounting frame 101, and the two tendon in-place indicator lights 302 are electrically connected to the two in-place micro switches respectively.

This structure can be more suitable for the welding of parabolic bellows tendons, and can prevent the bellows from loosening due to transportation and other problems after the crooked welding of the tendon. The tendon vertical positioning piece 3 can ensure the stability of the bellows positioning piece 2 placing the inner side of the tendon in the concave part of the bellows thread interval to prevent it from falling off. This structure can automatically detect when installing the tendon, and can adjust it in time if it is crooked. , which is more reasonable. When the horseshoe tendon and the horseshoe tendon mounting frame 101 are skewed to a large extent with respect to the verticality of the bellows, the bellows will squeeze one side of the rotating slider 201 and will slide on the horseshoe tendon mounting frame 101. At this time, the groove on the top of the rotating slider 201 will squeeze the pressing column 305, thereby controlling the pressing column 305 to squeeze the vertical micro switch 3011, thereby controlling the horseshoe tendon vertical indicator light 304 to light up. Ensure that when the two ends of the rotating slider 201 are in contact with the outer threaded protrusions of the bellows, the groove on the rotating slider 201 can be vertically aligned with the vertical micro switch 3011.

[0041] In the disclosed embodiment, the hand-held portion 4 includes: a hand-held handle 401, a rotating mounting arm 402 and a limit plate 403. The hand-held handle 401 is fixedly mounted on the side of the horseshoe tendon mounting frame 101; two rotating mounting arms 402 are fixedly mounted on the hand-held handle 401; the limit plates 403 are respectively fixedly mounted on the two rotating mounting arms 402; the two rotating mounting arms 402 are respectively provided with indicating arrows; the tube-attaching portion 6 includes: an angle swing arm 601, a bellows angle disk 6011 and a pressure plate 602; the angle swing arm 601 is provided with a bellows angle disk 6011; the bellows angle disk 6011 corresponds to the rotating mounting arm 402; the angle swing arm 601 is provided with a bellows angle disk 6011; the bellows angle disk 6011 corresponds to the rotating mounting arm 402; the angle swing arm 601 is provided with a bellows angle disk 6011; the bellows angle disk 6011 corresponds to the rotating mounting arm 402; the angle swing arm 601 is provided with a bellows angle disk 6011; the angle Indicator arrow on the mounting arm 402; a pressure plate 602 is rotatably mounted on the angle swing arm 601; the pressure plate 602 is used to fit the outside of the corrugated pipe. The pipe-fitting portion 6 can be used to facilitate observation of the installation accuracy of the corrugated pipe, ensuring that the corrugated pipe is parabolically erected on the positioning ribs of the prefabricated beam reinforcement cage. The observation is direct. When docking the horseshoe tendons, it automatically fits on the corrugated pipe for positioning measurement. Under the action of its own weight, the pressure plate 602 fits on the top of the corrugated pipe. At this time, the angle swing arm 601 will adapt to the vertical height of the corrugated pipe. At this time, observe the angle indicated by the indicator arrow on the rotating mounting arm 402 corresponding to the angle disk 6011 of the corrugated pipe, and it can be determined whether there is a deviation between the current position and the standard value.

[0042] In the disclosed embodiment, the preset prompt part 5 includes: a prompt winding disk 501 and a measuring ruler 502, the prompt winding disk 501 is rotatably mounted on the hand-held handle 401; a hand wheel is provided on the prompt winding disk 501; a measuring ruler 502 is wound on the prompt winding disk 501; a length scale line is provided on the measuring ruler 502; the preset prompt part 5 also includes: a bellows bending prompt angle 5021 and a hanging ring 503, a row of bellows bending prompt angles 5021 are provided on the measuring ruler 502, a row of bellows bending prompt angles 5021 are grouped in pairs, and each group of bellows bending prompt angles 5021 is used to prompt the reference angles of two pipe-attaching parts 6; a hanging ring 503 is fixedly installed on the end of the measuring ruler 502; the hanging ring 503 is used to hang on the end of the prefabricated beam reinforcement cage, and the preset prompt part 5 can be used at different positions as the welding progresses. The setting is used to prompt the standard values ​​of the two bellows angle disks 6011 at this position, so that the staff can quickly confirm the displayed values ​​of the bellows angle disks 6011, that is, the inclination of the bellows. This structure can be more suitable for the inspection of the installation accuracy of the long-distance prefabricated beam corrugated pipes to avoid omissions and time-consuming and labor-intensive measurement of the standard values ​​one by one. The prompt winding reel 501 is used to automatically follow the unwinding when the hand-held handle 401 is held, which is more practical and ensures the parabola accuracy of the bellows after welding. The bellows bending prompt angle 5021 is observed at the position corresponding to the welding horseshoe tendon. The displayed value of the bellows bending prompt angle 5021 is the value that the two bellows angle disks 6011 should display at this position. If the deviation is large, it cannot meet the standard and the bellows tension needs to be adjusted.

[0043] Embodiment 2, on the basis of embodiment 1, the spiral adjustment member 7 comprises: a spiral adjustment arm 701 and an adjustment drive motor 702, the spiral adjustment arm 701 is fixedly mounted at the bottom of the hand-held handle 401; the adjustment drive motor 702 is fixedly mounted on the spiral adjustment arm 701, and the output shaft of the adjustment drive motor 702 passes through the spiral adjustment arm 701; the spiral adjustment member 7 also comprises: a spiral drive wheel 703, the spiral drive wheel 703 is fixedly mounted on the end of the adjustment drive motor 702; a spiral protrusion is provided on the outer side of the spiral drive wheel 703; the spiral protrusion on the spiral drive wheel 703 is used to insert into the spiral interval of the corrugated pipe, and the use of the spiral adjustment member 7 can facilitate work Personnel can control the tension of the bellows to assist in pulling the bellows to achieve the purpose of correction. The structure is simple and labor-saving to use, and can cooperate with the inspection of the angle swing arm 601 to ensure the inclination accuracy of the prefabricated beam corrugated pipe during horseshoe tendon welding. Because there is a gap between the positioning ribs that support the bellows, the tension of the bellows after the positioning ribs directly affects the parabolic accuracy of the bellows, and the gap is prone to sinking. The structure can be corrected in time and use the shape of the bellows to ensure that it can be pulled by the spiral drive wheel 703. By controlling the forward and reverse rotation of the drive motor 702, the bellows will be pulled by friction drive to control the tension.

[0044] The working principle of this embodiment is as follows: first, the tendon magnet 102 is used to magnetically attract the tendon, and the tendon is inserted into the tendon installation frame 101. At this time, the tendon is inserted into the steel cage and the corrugated tube is sleeved. The positioning tendon magnet 103 is used to magnetically attract the positioning tendons on the prefabricated beam steel cage to ensure the fit between the positioning tendons and the tendons. The connecting steel sheet 104 is used to facilitate the manual adjustment of the welding gun 1041. After the tendon is sleeved into the corrugated tube, the tendon installation frame 101 is pressed downward. When the tendon is placed at the interval of the threaded protrusions of the corrugated tube, the threaded protrusions of the corrugated tube will squeeze the two pressing sheets 203, realizing the squeezing in place micro switch 202, and controlling the tendon in place indicator light 302 to light up. On the contrary, when the tendon is not accurately in place at the threaded protrusion interval, the two pressing sheets 203 will not be squeezed by the threaded protrusions of the corrugated tube at the same time, making full use of the structural style of the corrugated tube to improve the installation effect.When the tendon mounting frame 101 is pressed down and the tendon is pressed against the concave part of the thread interval of the bellows, the bottom of the rotating slider 201 will stick to the raised edge of the thread of the bellows. At this time, under the magnetic force of the positioning rib magnet 103, the bottom of the tendon will stick to the positioning rib. If the horseshoe tendon and the tendon mounting frame 101 are skewed greatly in verticality with the bellows, the bellows will squeeze one side of the rotating slider 201 and slide on the tendon mounting frame 101. At this time, the groove on the top of the rotating slider 201 will squeeze the pressing column 305 when it rotates, so as to control the pressing column 305 to squeeze the vertical micro switch 3011, thereby controlling the horseshoe tendon. The tendon vertical indicator light 304 is on, which means that the verticality of the horseshoe tendon and the bellows is not up to standard, which will cause the outer surface of the bellows to only squeeze one side of the rotating slider 201, causing the rotating slider 201 to slide and deviate. It is necessary to adjust the position of the horseshoe tendon docking the bellows. When the horseshoe tendon mounting frame 101 is inserted into the bellows in the steel cage, the pressure plate 602 is also driven to be inserted and fit on the top of the bellows under the action of its own weight. At this time, the angle swing arm 601 will adapt to the vertical height of the bellows. At this time, observe the corresponding rotation of the bellows angle plate 6011 The angle indicated by the indicating arrow on the installation arm 402 is that before holding the structure for welding, the hanging ring 503 is first hung on the end of the prefabricated beam reinforcement cage for positioning. As the staff moves to weld each horseshoe tendon, the measuring ruler 502 can be unwound on the prompt reel 501. At this time, the bellows bending prompt angle 5021 can be observed at the position corresponding to the welding horseshoe tendon. The displayed value of the bellows bending prompt angle 5021 is the normal value that the two observation bellows angle disks 6011 should display at this position. If the deviation is large, it cannot meet the standard and needs to be adjusted. When adjusting, the hand-held handle 40 set by hand is manually held 1. Drive the spiral drive wheel 703 upward. The spiral protrusion on the spiral drive wheel 703 is used to insert into the spiral interval of the corrugated pipe. By controlling the forward and reverse rotation of the drive motor 702, the corrugated pipe will be pulled by friction to control the tension. The lower the tension of the corrugated pipe, the easier it is to sink and bend. Compare and observe the display angle of the angle swing arm 601, and adjust it to the value displayed by the corrugated pipe bending prompt angle 5021 at this position. After the corrugated pipe correction dimensions meet the standards, the welding gun 1041 can be started to weld the positioning ribs and the horseshoe ribs on the outside of the corrugated pipe to ensure the accuracy of subsequent prestressing. ;
