[0002] In large concrete structures such as bridges and high-rise buildings, pier column steel reinforcement cage is a core load-bearing component, and its manufacturing precision directly affects the structural safety and construction quality. At present, the traditional mode of "manual line laying + simple moulding bed" is generally adopted for the processing of steel reinforcement cage: workers first insert longitudinal main reinforcement into the positioning holes or clamping slots of the moulding bed, and then manually wrap and bind the stirrups. The following problems exist in this process: after completing each section of steel reinforcement cage, multiple people need to pull out the limiting round steel or baffle on both sides of the moulding bed to separate the steel reinforcement cage from the moulding bed. For large-diameter and long-section steel reinforcement cage, the pulling resistance is large, time-consuming and labor-intensive, and the already bound stirrups are prone to displacement due to shaking; the traditional moulding bed is mostly a fixed welded structure, and the spacing between the main reinforcements is positioned by manual measurement or simple clamping slots, with an error of more than ±5mm. If the force is uneven during demoulding, it is easy to cause the ovality of the steel reinforcement cage to be out of tolerance or the stirrups to be deformed, and the subsequent installation needs to be corrected again.

DETAILED DESCRIPTION

[0017] The present application is further described below in conjunction with the accompanying drawings and examples.

[0018] Please refer to Figures 1-12 The present application provides a technical solution of a pier column reinforcement cage hydraulic tire frame: Example 1: According to Figures 1-6As shown, mainly includes the main body of the rack 1, truss system 2 and hydraulic drive device 3. The main body of the rack 1 is a cage-shaped cavity, which is composed of a channel steel base, a left rack 1a and a right rack 1b. The channel steel base is composed of a plurality of horizontal channel steels 101 laid equidistantly in the horizontal direction. The upper flange of each horizontal channel steel 101 serves as a bearing surface, and the lower flange directly falls on the ground or temporary support to form an overall load-bearing platform. The left rack 1a and the right rack 1b are parallel to each other and perpendicular to the channel steel base. The left rack 1a is vertically welded on the left side of the channel steel base as a fixed reference. The right rack 1b is slidably installed on the right side of the channel steel base and can move back and forth along the length direction of the horizontal channel steel 101. When the left rack 1a and the right rack 1b are closed, the left rack 1a, the right rack 1b and the channel steel base together enclose a rectangular cage-shaped space. When the right rack 1b moves outward, the left rack 1a and the right rack 1b move away from each other to realize automatic mold stripping of the main body of the rack 1. By setting the main body of the rack 1 as a split structure with one side fixed and the other side movable, the degree of freedom for subsequent hydraulic automatic mold stripping is provided, thereby avoiding the inefficient operation of manually pulling out the limiting components of the traditional rack.

[0019] The left rack 1a is an L-shaped frame composed of a plurality of vertical columns 102 and horizontal channel steels 101. The right rack 1b is composed of a plurality of vertical columns 102 perpendicular to the horizontal channel steels 101 without contacting them. The vertical columns 102 in the left rack 1a and the right rack 1b are oppositely arranged, and each group of vertical columns 102 corresponds to a horizontal channel steel 101. A rectangular cage is formed by two vertical columns 102 and a horizontal channel steel 101. A plurality of positioning clamping plates 104 are welded and fixed on the vertical columns 102 of the left rack 1a and the right rack 1b and the channel steel base in the direction of the main body of the rack 1. The positioning clamping plates 104 connect multiple rectangular cages to form the main body of the rack 1. The positioning clamping plates 104 are arranged in rows on the channel steel base, the left rack 1a and the right rack 1b of the main body of the rack 1, and the clamping slots on the positioning clamping plates 104 have the same opening direction. The clamping slots are used for precise positioning of the longitudinal main reinforcement, and the spacing of the clamping slots is based on the arrangement spacing and density of the reinforcement. Compared with the traditional manual line laying, the positioning clamping plate 104 controls the main reinforcement spacing error within ±2mm, and the depth of the clamping slot is slightly larger than the radius of the reinforcement, which ensures the positioning accuracy and facilitates the quick placement or removal of the reinforcement.

[0020] Short sleeves 103 are welded equidistantly along the height direction on the inner side of each vertical column 102 of the left rack 1a and the right rack 1b. The sleeves 103 are used to insert support rods to provide space for placing and supporting the reinforcement, facilitating the placement and bundling of the reinforcement. The insertion position and number of the support rods can be reasonably set according to the actual needs of the reinforcement bundling operation.

[0021] The truss system 2 is a bridge connecting the right jig frame 1b and the hydraulic drive device 3, which is composed of three parts of a support frame plate 201, a rectangular frame 202 and a bottom frame 203. The support frame plate 201 is directly welded on the outer side of the right jig frame 1b, so that the right jig frame 1b is uniformly stressed as a whole, the rectangular frame 202 is welded and fixed on the outer side of the support frame plate 201 to realize local reinforcement, and the support effect provided by the support frame plate 201 and the rectangular frame 202 makes the right jig frame 1b not be twisted and deformed under the action of the hydraulic thrust force. The bottom frame 203 is horizontally fixed on the slide 303 of the hydraulic drive device 3 by bolts. Through the truss system 2, the concentrated force output by the hydraulic cylinder 306 is converted into a uniformly distributed thrust force along the height direction of the right jig frame 1b, so as to ensure the smooth and non-stuck process of the mold clamping / mold stripping.

[0022] As shown in Figure 5 , the hydraulic drive device 3 is composed of two inclined seats 301, a slide 303, a hydraulic cylinder 306 and an auxiliary slide-plate pair. The two inclined seats 301 are connected together by an I-shaped steel 302, and a reinforcing channel steel 307 is welded and fixed on the inclined seats 301 to improve the strength of the connection. The inclined seats 301 are inclined downward by about 10°-15°, the slide 303 is slidingly sleeved on the inclined seats 301 and can slide along the inclined surface of the inclined seats 301, the slide 303 is provided with a slide 308, and the slide 303 is provided with a slide plate 309 matched with the slide 308 at the bottom. The slide 303 is slidingly sleeved on the slide 308 through the slide plate 309 at the bottom. Two groups of longitudinally arranged support columns 304 are symmetrically installed on the slide 303, and the bottom frame 203 of the truss system 2 is horizontally installed on the support columns 304 by bolts. The center position of the I-shaped steel 302 and the center position of the slide 303 are both provided with a mounting seat 305, the cylinder body of the hydraulic cylinder 306 is hinged to the mounting seat 305 on the I-shaped steel 302, and the piston rod end is hinged to the mounting seat 305 of the slide 303, forming an inclined slide-tube cylinder mechanism.

[0023] As shown in Figure 6 , when the piston rod is extended, the slide 303 moves upward along the inclined seats 301, and the right jig frame 1b approaches the left jig frame 1a to complete mold clamping; when the piston rod is retracted, the right jig frame 1b retreats obliquely downward to complete mold stripping. By setting the inclined seats 301 as inclined surfaces, on the one hand, the gravitational component force is used to reduce the return load of the hydraulic cylinder 306, and on the other hand, the right jig frame 1b produces a combined motion of "outward + downward" when stripping, quickly separates from the reinforcement cage, and converts the huge friction force required by the traditional horizontal push-pull into controllable inclined sliding, which significantly reduces energy consumption and improves the stability of the action.

[0024] In specific use, before the reinforcement cage is formed, the piston rod of the hydraulic cylinder 306 is extended, the sliding seat 303 is pushed to slide obliquely upward along the inclined seat 301, the sliding seat 303 drives the right jig 1b to move towards the left jig 1a through the truss system 2, and the jig body 1 is completed. At this time, the channel steel base, the left jig 1a, the right jig 1b and the positioning clamping plate 104 jointly form a closed rectangular cavity, and the longitudinal main reinforcement can be directly positioned in the clamping groove of the positioning clamping plate 104; after the binding of the stirrup is completed, the hydraulic cylinder 306 is reversely retracted, the right jig 1b retreats along an obliquely downward trajectory, and is quickly separated from the reinforcement cage. The whole stripping process does not need to manually pull out any limiting part, and can be completed only by relying on the low-friction sliding of the obliquely arranged sliding table 308, thereby significantly reducing the labor intensity and avoiding the deformation of the reinforcement cage.

[0025] Example two: on the basis of example one, the same parts of the example two and example one will not be repeated, and the different parts are as follows: the support rod provided in example one is improved in this example.

[0026] As shown in Figures 7-12 , a support rod assembly 5 is used here. The support rod assembly 5 is divided into two groups of left support rods 51 and right support rods 52, and the left support rods 51 and the right support rods 52 are arranged in rows along the vertical columns 102 of the left jig 1a and the right jig 1b respectively. Its function is to provide internal limiting for the longitudinal main reinforcement in the closed die state, so as to prevent the steel bar from tilting inward or falling off during binding or transportation.

[0027] Specifically, as shown in Figure 8 , a rotatable rotating rod 512 is coaxially sleeved in the left support rod 51, and a left blocking rod 514 is vertically welded at the inner end of the rotating rod 512. The left blocking rod 514 can rotate 90° with the rotating rod 512: when the left blocking rod 514 is in the vertical state, it can provide limiting for the steel bar, and when the left blocking rod 514 is in the horizontal state, it releases the limiting, which is convenient for the reinforcement cage to exit; the right end of the right support rod 52 is vertically welded with a right blocking rod 522, and the right blocking rod 522 always maintains a vertical posture. Through the limiting effect provided by the left blocking rod 514 and the right blocking rod 522, reliable constraint can be provided for the steel bars placed by the reinforcement cage in the forming stage, and the steel bars can be effectively prevented from falling off.

[0028] The state switching of the left blocking rod 514 is controlled by a control structure, which mainly includes a torsion spring 513 and a pull rope 9. The torsion spring 513 is pre-installed between the rotating rod 512 and the left support rod 51, and the torsion spring 513 provides the rotating rod 512 with torsion and reset functions. An arc-shaped through groove 511 is longitudinally opened on the left support rod 51, and a through hole 515 is opened on the rotating rod 512 at a position corresponding to the arc-shaped through groove 511. A pull rope 9 is passed through the through hole 515. The pull rope 9 passes through the left support rod 51 on the same column 102 in sequence. The pull rope 9 connects the upper and lower adjacent left support rods 51 together, and the upper end of the pull rope 9 is fixedly connected to the top plate 8 on the top of the column 102, and the lower end of the pull rope 9 is connected to the stepping ring 4. When the tire frame body 1 is in the normal state of mold closing, the torsion spring 513 is in a relaxed state, and the left blocking rod 514 extends vertically to block the steel bars; when the mold needs to be withdrawn, the worker steps on the stepping ring 4 to drive the pull rope 9 to move downward. The pull rope 9 is tightened and drives all the rotating rods 512 to rotate 90 degrees synchronously through the through holes 515 that penetrate the left support rods 51 of each layer, so that the left blocking rod 514 changes from vertical to horizontal, instantly releasing the limit on the steel cage. Figure 11 At the same time, the torsion spring 513 is energized during this process. After the stepping ring 4 is released, the torsion spring 513 releases energy, and the left lever 514 automatically resets to vertical, preparing for the next cycle. This method greatly improves the efficiency of demoulding.

[0029] The withdrawal of the right lever 522 is accomplished by the cooperation of the spring 521 and the hydraulic cylinder 306. Figure 9 As shown, the right support rod 52 is horizontally slidably sleeved in the sleeve 103, and a spring 521 is sleeved on the right support rod 52. The two ends of the spring 521 are respectively connected to the boss at the outer end of the right support rod 52 and the sleeve 103. The compression effect of the spring 521 can provide a certain buffer space for the right baffle 522. When the tire frame is closed, the spring 521 is in a free extension state, and the right baffle 522 provides a limit for the main reinforcement; when the mold is withdrawn, the hydraulic cylinder 306 drives the right tire frame 1b to retreat obliquely downward. The right baffle 522 first maintains its position due to the weight of the steel cage. As the right tire frame 1b retreats, the spring 521 is gradually compressed, providing a certain retention distance for the right baffle 522. When the spring 521 is compressed to the limit, the hydraulic cylinder 306 synchronously drives the right tire frame 1b and the right baffle 522 to retreat. Rod 522 pulls the steel cage to the right, so that the steel cage is out of the range of the left stop rod 514; then the right tire frame 1b and the steel cage continue to retreat. When the retreat height of the right tire frame 1b exceeds the height of the right stop rod 522, the right stop rod 522 automatically retreats from under the main reinforcement of the steel cage, releasing the limit on the steel cage. At the same time, the spring 521 provides a buffering effect for the right stop rod 522, so that it can smoothly detach from the steel cage without collision. At this time, the limits on both sides of the steel cage are released, so as to facilitate the lifting operation.

[0030] The height of the right blocking rod 522 is less than the stripping stroke, that is, the height of the right blocking rod 522 is always less than the height displacement difference of the right bed 1b from the clamping to the complete stripping, so that the right blocking rod 522 cannot be secondarily interfered with the reinforcement cage during the stripping process, and the smoothness of the stripping is further improved.

[0031] The support rod assembly 5 is arranged at least in two groups and symmetrically arranged at the front and rear ends of the left bed 1a and the right bed 1b, forming a four-point or multi-point positioning layout, so that the reinforcement cage is uniformly stressed in the longitudinal direction, and the straightness of the finished reinforcement cage is ensured.

[0032] In specific use, the pier reinforcement cage hydraulic bed of the application, in the clamping stage, the left blocking rod 514 is kept vertical under the action of the torsional spring 513, and the right blocking rod 522 is kept extended under the action of the spring 521, both of which form a limit for the steel bars, ensuring that the longitudinal bars will not fall or be misaligned during the binding process; when stripping, the worker steps on the pedal ring 4, the pull rope 9 drives all the rotating rods 512 in the left support rod 51 to rotate synchronously by 90°, the left blocking rod 514 is turned from vertical to horizontal, and the left side limit is instantly released; at the same time, the hydraulic cylinder 306 drives the right bed 1b to retreat obliquely downward, and the right blocking rod 522 obtains a certain buffer stroke due to the compression of the spring 521, and then retreats with the right bed 1b until completely separated from the bottom edge of the reinforcement cage, realizing smooth stripping without collision and jamming; the resetting force of the torsional spring 513 ensures that the left blocking rod 514 can be automatically reset in the next cycle, and the whole process is simple to operate.

[0033] In example three, based on example two, pin holes 6 are opened on the left support rod 51, the right support rod 52 and the corresponding sleeve 103, the pin holes 6 are used for inserting pins 7, and the locking and unlocking of the support rod assembly 5 and the sleeve 103 are realized through the cooperation of the pins 7 and the pin holes 6. Specifically, since the left support rod 51 needs to be fixedly sleeved in the sleeve 103 to realize the rotation of the rotating rod 512, the left support rod 51 and the corresponding sleeve 103 are locked through the pins 7 and the pin holes 6; since the right support rod 52 needs to cooperate with the spring 521 to realize a certain distance buffer, the right support rod 52 does not need to be locked.

[0034] The above only describes the preferred embodiments of the application, and does not limit the application, any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
