Description

Technical Field

[0001] The present invention relates to the technical field of steel bar winding machines, and specifically discloses a steel bar cage winding machine for precast components. Background Art

[0002] The steel bar cage is a steel bar structure in the casting and forming of precast components such as bored cast-in-place piles, dug piles, and columns. It is necessary to process the steel bar cage and place it inside the casting mold before concrete pouring. The steel bar cage winding machine is a relatively common device currently used for preparing steel bar cages. It mainly consists of a walking wire feeding mechanism and a steel bar cage rolling mechanism. During the process of winding the steel bar cage, the steel bar cage frame is placed on two rows of supporting rollers on the steel bar cage rolling mechanism. The two rows of supporting rollers are driven by a motor and a chain, so that the steel bar cage frame rotates around its own central axis on the two supporting rollers. Then, during the rotation process, the steel wire is evenly fed and walked through the walking wire feeding mechanism to wind around its outer surface.

[0003] For example, the utility model patent with the application number CN2019220985396 discloses a steel bar cage winding machine. The rolling device of this winding machine includes a main frame, a rolling mechanism, a power mechanism, and a transmission mechanism; the transmission mechanism includes a first transmission shaft and a second transmission shaft. The rolling mechanism is connected to the first transmission shaft and the second transmission shaft through a cross universal coupling. The rolling mechanism includes two groups of parallel winding roller groups, and each group of winding roller groups includes at least two winding rollers connected end to end. The winding rollers are connected through a cross universal coupling. The steel bar cage winding machine disclosed in this patent is a relatively common steel bar cage winding machine on the current market and is widely used. However, this steel bar cage winding machine has the following three deficiencies in actual use. First, since the steel bar cage frame rotates by relying on the friction force with the supporting rollers, when relative sliding occurs between the supporting rollers and the steel bar cage frame, due to the fact that the walking wire feeding mechanism still walks and feeds wire at a constant speed, the winding wire spacing on the steel bar cage frame is not equal; second, the two rows of supporting rollers are fixedly arranged and driven by transmission components such as motors and chains, resulting in the distance between the two rows of supporting rollers being unable to be adjusted. When winding steel bar cages of different sizes, it is necessary to adjust the distance between the two rows of supporting rollers to effectively ensure the effective support during the rotation of the steel bar cage; third, after the steel bar cage winding of this winding machine is completed, due to the significant increase in the weight of the steel bar cage, at least two operators are required to push it from one side to unload it from the supporting rollers. The entire unloading process has a large labor intensity and there is a certain degree of danger. Therefore, in view of the above deficiencies of the existing steel bar cage winding machines, this application proposes a steel bar cage winding machine for precast components that can effectively solve the above three technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel bar cage winding machine for precast components to solve the three technical problems raised in the background art during the use of the existing steel bar cage winding machines.

[0005] The present invention is realized through the following technical solutions:

[0006] A bar winding machine for a precast member steel reinforcement cage includes a cage frame rolling mechanism, a walking wire laying mechanism, and a walking track. The cage frame rolling mechanism includes a bottom plate and a machine base. The machine base is movably arranged at one end of the bottom plate along the direction of the walking track. A driving assembly is arranged on the machine base and is movably arranged along a direction perpendicular to the walking track. The output end of the driving assembly is connected with a cage frame connecting frame.

[0007] An adjusting push groove is formed on the upper surface of the bottom plate. A rectangular block is arranged in the adjusting push groove. A second telescopic driving member for pushing the rectangular block to move along a direction perpendicular to the walking track is arranged on the bottom plate. A row of supporting rollers is arranged on the upper surfaces of both the bottom plate and the rectangular block.

[0008] As a further setting of the above solution, an inclined surface is arranged at the inner end of the adjusting push groove. An inclined surface opening matching the inclined surface is formed at the side end of the rectangular block. The end of the second telescopic driving member is movably connected with the rectangular block.

[0009] As a further setting of the above solution, a material guiding block is arranged on the side surface of the bottom plate on the side away from the rectangular block.

[0010] As a further setting of the above solution, a second slide rail is arranged on the bottom wall of the adjusting push groove. A sliding opening matching the second slide rail is formed on the lower surface of the rectangular block.

[0011] As a specific setting of the above solution, a first track arranged along the direction of the walking track is arranged on the bottom plate. The machine base is movably arranged on the first track. A first telescopic driving member for pushing the machine base is arranged at the end of the bottom plate.

[0012] As a specific setting of the above solution, a limiting sliding groove arranged perpendicular to the direction of the walking track is formed on the machine base. A sliding block matching the limiting sliding groove is arranged at the lower end of the driving assembly. An adjusting lead screw is arranged in the limiting sliding groove, and a hand wheel is connected to the end of the adjusting lead screw. A threaded hole matching the adjusting lead screw is formed on the sliding block.

[0013] As a specific setting of the above solution, the driving assembly includes a speed reducer and a driving motor. The driving motor is connected to the input shaft of the speed reducer. The cage frame connecting frame is connected to the output shaft of the speed reducer.

[0014] As a specific setting of the above solution, the cage frame connecting frame includes an end block. A plurality of inserting pipes are connected to the outer circular surface of the end block. A connecting rod is arranged in each inserting pipe. The outer end of the connecting rod is connected with a steel bar main bone penetrating pipe. A fastening assembly for fixing the connecting rod is arranged on the inserting pipe.

[0015] As a specific setting of the above solution, the fastening assembly includes an adjusting bolt threadedly connected to the insertion tube. The inner end of the adjusting bolt is connected with an engaging tooth block, and a tooth surface matching the engaging tooth block is arranged on the side surface of the connecting rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the steel bar winding machine disclosed by the present invention winds steel bars on the steel bar cage frame, it is supported by two rows of supporting rollers, and then the cage frame connecting frame at the output end of the driving assembly is inserted through the main steel bars at the ends of the steel bar cage frame. During the winding process, the rotation of the steel bar cage frame is realized through the driving assembly, and the two rows of supporting rollers only provide a supporting role, so that it can effectively avoid the problem that the existing steel bar winding machine is prone to relative sliding during the rotation and winding process of the steel bar cage frame due to the rotation of the supporting rollers, resulting in inconsistent winding spacing, effectively ensuring the winding dimension accuracy of the steel bar cage and improving the product quality.

[0018] The distances between the two rows of supporting rollers and the radial size of the cage frame connecting frame of the steel bar winding machine disclosed by the present invention can be quickly adjusted according to the steel bar cage frames with different diameters, so that the whole steel bar winding machine can be applicable to the winding processing of steel bar cages with various sizes. At the same time, by adjusting the distances between the two rows of supporting rollers, the steel bar cage frames with different sizes can be stably supported to ensure the smooth progress of the winding process.

[0019] The steel bar winding machine disclosed by the present invention further improves the design on the basis that the distances between the two rows of supporting rollers are adjustable. Through the cooperation between the inclined surface on the pushing groove and the inclined surface opening on the rectangular block, when it is necessary to unload the coil after the winding is completed, the rectangular block is directly pushed towards the inclined surface direction, and then the rectangular block moves upward under the action between the rectangular block and the inclined surface opening, so that the supporting roller on the rectangular block is higher than the supporting roller on the bottom plate. At this time, the center of gravity of the whole steel bar cage moves to the outside of the supporting roller on the bottom plate, and then the whole steel bar cage can automatically roll down from the supporting roller under the action of gravity, realizing the process of automatic unloading and effectively solving the deficiency that the existing steel bar winding machine needs manual unloading.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will refer to the attached Figures 1 - 9 , and will describe the present application in detail in conjunction with the embodiments. Embodiment

[0032] Embodiment 1 discloses a precast member steel bar cage winding machine, referring to the attached Figure 1, the main body of the spiral bar winding machine consists of a cage frame rolling mechanism 100, a wire feeding and traveling mechanism 200, and a traveling track 300. Among them, the traveling track 300 is arranged in parallel on one side of the cage frame rolling mechanism 100, and the wire feeding and traveling mechanism 200 is arranged on the traveling track 300. During the process of winding bars around the steel cage frame, the cage frame rolling mechanism 100 rotates the steel cage frame around its own central axis, and then the wire feeding and traveling mechanism 200 evenly feeds the wire during the process of traveling at a constant speed on the traveling track 300, and then the released steel wire is evenly wound around the outer circular surface of the steel cage frame being wound.

[0033] Refer to the appendix Figure 2 , the wire feeding and traveling mechanism 200 includes a base 201, and two rows of rollers 202 matching the traveling track 300 are arranged on the lower surface of the base 201. A wire reel holder 203 is rotatably arranged on the upper surface of the base 201, and a wire feeding motor 204 is arranged on the base 201 beside the wire reel holder 203. The wire feeding motor 204 and the lower end rotating shaft of the wire reel holder 203 can be driven by a chain or a belt. When it is necessary to control the wire feeding speed, directly control the rotation speed of the wire feeding motor 204.

[0034] A fixing frame 205 is arranged on the base 201 close to the cage frame rolling mechanism 100, a steel wire straightener 206 is arranged at the upper end of the fixing frame 205, and the angle of the discharging end of the steel wire straightener 206 can be adjusted according to actual requirements. During the wire feeding process, the steel wire coil is sleeved on the wire reel holder 203, and then the wire feeding motor 204 is started to make the wire reel holder 203 rotate at a constant speed. Then the released steel wire is straightened by the steel wire straightener 206 and then wound around the outer surface of the steel cage frame on the cage frame rolling mechanism 100. In addition, a traveling driving device (which is a prior art and is not illustrated and described in this embodiment) is also arranged on the wire feeding and traveling mechanism 200, as long as it can control the entire wire feeding and traveling mechanism 200 to travel at a set speed at a constant speed on the traveling track 300.

[0035] Refer to the appendix Figure 3 and the appendix Figure 4, the cage frame rolling mechanism 100 includes a long strip-shaped bottom plate 101. A first slide rail 102 is provided on the upper surface of the bottom plate 101, and the first slide rail 102 is arranged parallel to the walking track 300. A machine base 103 is movably arranged on the first slide rail 102, and a first telescopic driving member 104 for driving the machine base 103 to move along the first slide rail 102 is provided at the end of the bottom plate 101. Specifically, the first telescopic driving member 104 can be selected from a cylinder or a hydraulic cylinder. A limit chute perpendicular to the walking track 300 is provided on the upper surface of the machine base 103, and an adjusting screw rod (not shown in the figure) is arranged in the limit chute. The end of the adjusting screw rod is connected with a hand wheel 105 extending out of the side end of the machine base 103. A speed reducer 106 is provided above the limit chute. A slider 107 moving along the limit chute is welded to the lower surface of the speed reducer 106, and a threaded hole matching the adjusting screw rod is provided on the slider 107. A driving motor 108 is fixedly installed on the speed reducer 106. The driving motor 108 is connected to the input shaft of the speed reducer 106, and then a cage frame connecting frame 400 is connected to the end of the output shaft of the speed reducer 106.

[0036] Refer to the attached Figure 4 and the attached Figure 6 , the cage frame connecting frame 400 includes an end block 401 connected to the end of the output shaft of the speed reducer 106. A plurality of inserting pipes 402 are connected to the circumferential side surface of the end block 401, and a telescopically adjustable connecting rod 403 is inserted in the inserting pipes 402. A tooth surface 404 is provided on one side surface of the connecting rod 403, and an adjusting bolt 405 provided for the tooth surface 404 is threadedly connected to the inserting pipe 402. Then, an engaging tooth block 406 is movably connected to the inner end of the adjusting bolt 405. When it is necessary to fix the connecting rod 403 in the inserting pipe 402, directly turn the adjusting bolt 405 so that the engaging tooth block 406 presses on the tooth surface 404. Finally, a main reinforcement pipe 407 is connected to the outer end of each connecting rod 403. The inner diameter of the main reinforcement pipe 407 is slightly larger than the diameter of the main reinforcement of the steel cage frame, so as to facilitate its penetration connection with the end of the steel cage frame.

[0037] Refer to the attached Figure 3 and the attached Figure 5, an adjustment and push groove 109 is formed on the upper surface of the bottom plate 101. A second slide rail 110 for the vertical travel rail 300 is provided on the bottom wall of the adjustment and push groove 109. Then, a rectangular block 111 is arranged in the adjustment and push groove 109. A sliding opening matching the second slide rail 110 is formed on the lower surface of the rectangular block 111. Meanwhile, a second telescopic driving member 112 extending into the adjustment and push groove 109 and connected to the rectangular block 111 is arranged on the side surface of the bottom plate 101. The second telescopic driving member 112 can also be a cylinder or a hydraulic cylinder. A row of idler rollers 113 is fixedly installed on the upper surfaces of the rectangular block 111 and the bottom plate 101 respectively. The two rows of idler rollers 113 are both arranged parallel to the travel rail 300, and the horizontal heights of the two rows of idler rollers 113 should be kept at the same height position.

[0038] During the operation of the precast member steel cage winding machine disclosed in Embodiment 1, first, adjust the distance between the two rows of idler rollers 113 and the position of the steel bar main bone through pipe 407 on the cage frame connecting bracket 400 according to the diameter of the steel cage to be wound. Then, rotate the handwheel 105 to adjust the cage frame connecting bracket 400 to the mid-perpendicular plane of the connection line of the two rows of idler rollers 113.

[0039] After the above adjustments are completed, place the steel cage frame into the two rows of idler rollers 113. Then, start the first telescopic driving member 104 to move the machine base 103 towards the end of the steel cage frame, so that the steel bar main bone at the end of the steel cage frame passes through the steel bar main bone through pipe 407 on the cage frame connecting bracket 400. Next, lead the steel wire on the wire walking and paying-off mechanism 200 through the wire straightener 206 and then weld and fix it to the outer circular surface of the steel cage frame. Then, simultaneously start the driving motor 108 on the cage frame rolling mechanism 100, the pay-off motor 204 on the wire walking and paying-off mechanism 200 and the walking driving device to start uniform winding. During the winding process, the operator can perform spot welding. Embodiment

[0040] Embodiment 2 discloses a precast member steel cage winding machine which is an improved design based on Embodiment 1. The wire walking and paying-off mechanism 200 and the travel rail 300 in Embodiment 2 are the same as those in Embodiment 1. The main difference lies in the further setting of the cage frame rolling mechanism 100, so that the whole steel cage can be automatically unloaded after the steel cage winding is completed.

[0041] The same parts of Embodiment 2 and Embodiment 1 will not be described again. The differences are referred to in Appendix Figure 7 and Appendix Figure 8 . In Embodiment 2, an inclined surface 1091 is arranged at the inner end of the adjustment and push groove 109. Meanwhile, an inclined surface opening 1111 matching the inclined surface 1091 is formed at the side end of the rectangular block 111 facing the inclined surface 1091.

[0042] A vertical chute 1112 corresponding to the second telescopic driving member 112 is provided on the outer side surface of the rectangular block 111. A limiting slider is arranged in the vertical chute 1112, and then the telescopic end of the second telescopic driving member 112 is connected to the limiting slider. In addition, a material guiding block 114 is provided on the surface of the bottom plate 101 on the side far from the adjusting push groove 109.

[0043] In this Embodiment 2, through the above improved design of the rectangular block 111 and the adjusting push groove 109, when it is necessary to unload the material after the steel cage is wound, the second telescopic driving member 112 is started to move the rectangular block 111 in the direction of the inclined surface 1091, so that the distance between the two rows of idler rollers 113 gradually becomes smaller. When the inclined surface opening 1111 on the rectangular block 111 is in contact with the inclined surface 1091, the rectangular block 111 will gradually move upward under the continuous pushing of the second telescopic driving member 112. At this time, the idler roller 113 on the rectangular block 111 is higher than the idler roller 113 on the bottom plate 101 (refer to the appendix Figure 9 ), and as the two rows of idler rollers 113 approach each other, the center of gravity of the entire steel cage moves to the outside of the row of idler rollers 113 on the bottom plate 101. Therefore, under the action of gravity, the entire steel cage can automatically roll off the idler rollers 113 onto the material guiding block 114, and then the material guiding block 114 guides it to the ground, realizing the process of automatic unloading.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
