Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for manufacturing a steel cage, and in particular to a tire frame for manufacturing a pier column steel cage. Background Art

[0002] In the construction of bridge piers, materials were previously transported to the construction site, and steel cages for piers were made on site. However, making steel cages on site is not only inefficient, but also takes up a lot of space. Therefore, steel cages are mostly pre-made in factories and then transported to the construction site for installation, which not only improves the efficiency of bridge pier construction, but also greatly reduces environmental pollution problems such as noise, dust and traffic on the construction site. At the same time, prefabrication technology reduces the difficulty and complexity of on-site construction, making the construction of bridge piers more efficient and reliable.

[0003] When the steel cage of the vase pier is made, the steel cage is mostly made into a square shape. Since the steel cage is large, it is often assisted by a tire frame to initially position multiple longitudinal reinforcements, and then evenly put on transverse stirrups, and finally manually bind them to make the steel cage. However, when the tire frame is assembled with the steel cage, manpower is mostly used to adjust and assemble the tire frame, which has low work efficiency. When the steel cage and the tire frame are separated, there are safety hazards in manually adjusting the tire frame, and the size of the steel cage made of the traditional tire frame is relatively fixed. Utility Model Content

[0004] The purpose of the utility model is to provide a tire frame for making pier column steel cages, which solves the problems that traditional tire frames mostly rely on manpower to adjust and assemble the tire frames, resulting in low work efficiency, potential safety hazards in manually adjusting the tire frames when the steel cages and the tire frames are separated, and the relatively fixed size of the steel cages made of traditional tire frames.

[0006] The tire frame assembly comprises a left support member, a right support member and a top support arm, wherein the left support member and the right support member have the same structure and are arranged symmetrically on both sides;

[0007] The left support member comprises a bracket, a side support arm, a first push cylinder and a positioning arm, the bracket is arranged on the base, one end of the side support arm is hinged to an end of the bracket away from the right support member, and the two ends of the first push cylinder are respectively hinged to the bracket and the side support arm; the free ends of the two side support arms are respectively detachably connected to the two ends of the top support arm;

[0008] It also includes a connecting arm, wherein the positioning arm is vertically arranged at one end of the bracket close to the right support member, and the tops of the two positioning arms are detachably connected to the two ends of the connecting arm respectively;

[0009] A pad is provided on the top of the bracket, a plurality of first grooves are provided on the pad at intervals, and a plurality of second grooves are provided on the top of the connecting arm at intervals; a plurality of support blocks are provided on the side support arm at intervals, a third groove is provided on the top of the support block, a plurality of L-shaped hooks are provided at intervals on the bottom of the top support arm, and a fourth groove is provided on the top of the horizontal part of the L-shaped hook;

[0010] The first groove, the second groove, the third groove and the fourth groove are parallel to each other.

[0011] Furthermore, a plurality of auxiliary positioning members are vertically spaced apart on the positioning arm, and the auxiliary positioning members include a support rod and a cushion block, the support rod is rotatably arranged at the front side of the positioning arm, the cushion block is arranged on the rotation path of the support rod, and the top of the cushion block abuts against the support rod to keep the support rod in a horizontal state;

[0012] When the support rod is kept in a horizontal state, the free end thereof extends out of the positioning arm to a side away from the right support member, and a fifth groove is arranged on the top of the portion of the support rod horizontally extending out of the positioning arm, and the fifth groove is parallel to the fourth groove.

[0013] Furthermore, an embedding groove is provided at the top of the positioning arm, and pin blocks are provided at the bottoms of both ends of the connecting arm, and the two pin blocks are respectively embedded in the two embedding grooves.

[0014] Furthermore, the two side arms are hinged with a locking rod on one side away from each other, and both ends of the top support arm are provided with a locking groove, and the locking groove is located on the rotation path of the locking rod;

[0015] A locking block is threadedly connected to the locking rod, so that after the locking rod is placed in the locking slot, the locking block abuts against the top of the locking slot, thereby connecting the side support arm to the top support arm.

[0016] Furthermore, the right support member is slidably arranged on the base, a second push cylinder is arranged on the bracket of the left support member, and a telescopic end of the second push cylinder is connected to the bracket of the right support member.

[0017] Furthermore, it also includes a third push cylinder and a push plate. The third push cylinder is vertically arranged on the two brackets, and the telescopic end of the third push cylinder is connected to the push plate. The push plate moves up and down through the third push cylinder.

[0018] Furthermore, a plurality of sixth grooves are arranged on the push plate at intervals, and the sixth grooves are parallel to the first grooves.

[0019] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0020] 1. Before assembling the steel cage, a number of longitudinal steel bars are first horizontally placed on two supporting members of a number of frame assemblies, and then transverse stirrups are put on the plurality of longitudinal steel bars and evenly arranged between the plurality of frame assemblies. The portions of the longitudinal steel bars extending out of the frame at both ends can finally be covered with transverse stirrups, and then the two side support arms are respectively pushed to a vertical state by two first push cylinders, and the free ends of the two side support arms are connected to each other by the top support arm. At this point, the two brackets, the two side support arms and the top support arm form a rectangular frame shape; after placing a number of longitudinal steel bars in the first groove, the second groove, the third groove, the fourth groove and the fifth groove respectively, and then evenly distributing a number of transverse stirrups on the longitudinal steel bars, binding can be started. After binding and reinforcement, a steel cage is made, which eliminates the need for workers to manually radially position and then bind each longitudinal steel bar in the traditional steel cage manufacturing process, thereby greatly improving the efficiency and quality of steel cage manufacturing.

[0021] 2. When the steel cage is tied, turn the lock block to separate it from the lock slot on the top support arm until the lock rod can carry the lock block to rotate and then separate it from the lock slot to separate the top support arm from the side support arm. Then control the steel cage to move slightly upward, and then move the top support arm horizontally to the right to separate the L-shaped hook from the longitudinal steel bar, and then move it vertically upward to remove the top support arm, and then control the two first push cylinders to separate the two side support arms from the steel cage. You can use a gantry truck or other hoisting equipment to lift the steel cage. It should be noted that it needs to move vertically upward a certain distance when lifting. The distance between the steel cage and the positioning arm is large enough to separate the steel cage and then move horizontally. When the steel cage is separated from the positioning arm, the longitudinal steel bars below the auxiliary positioning piece will first drive the support rod in the auxiliary positioning piece above it to rotate upward when passing over the positioning steel bars above it, until it is separated from it. The support rod returns to a horizontal state under the action of gravity, and this process is repeated until the steel cage is separated from it. When the support rod falls, it is limited by the pad and continues to maintain a horizontal state, so as to position the longitudinal bars of the next steel cage. Only the top support arm needs to be manually installed and removed, which greatly improves production efficiency and safety.

[0022] 3. The distance between the two brackets can be controlled by the second push cylinder, so as to realize the manufacture of steel cages of different widths. According to the needs, top support arms and connecting arms of corresponding lengths need to be adopted. If necessary, the lengths of the two side arms can also be replaced.

[0023] 4. When the third push cylinder is in the retracted state, the push plate is flush with the pad on the top of the bracket, the sixth groove corresponds to the first groove one by one and is in the same horizontal plane, thereby realizing the auxiliary positioning of the longitudinal steel bars. When the steel cage is tied, it is difficult to lift it vertically with traditional lifting equipment, and then the third push cylinder can be used to push the steel cage upward, first facilitating the separation of the top support arm, and then facilitating the separation of the steel cage and the two positioning arms, greatly improving operational safety and production efficiency.

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment one:

[0036] Reference Figures 1 to 6 As shown, this embodiment provides a tire frame for making a pier column reinforcement cage, including a base 1, on which a plurality of tire frame components 2 are arranged in parallel and at intervals; according to the required length of the reinforcement cage, an appropriate number of tire frame components 2 are arranged or used.

[0037] The tire frame assembly 2 includes a left support member 21, a right support member 22 and a top support arm 23. The left support member 21 and the right support member 22 have the same structure and are symmetrically arranged.

[0038] More specifically, the left support member 21 includes a bracket 211, a side support arm 212, a first push cylinder 213 and a positioning arm 214. The bracket 211 is arranged on the base 1, one end of the side support arm 212 is hinged to the end of the bracket 211 away from the right support member 22, and the two ends of the first push cylinder 213 are respectively hinged to the bracket 211 and the side support arm 212, and then the rotation of the corresponding side support arm 212 is realized by the first push cylinder 213; the free ends of the two side support arms 212 are respectively detachably connected to the two ends of the top support arm 23. In specific implementation, in the steel cage assembly Before installation, a number of longitudinal steel bars are first horizontally placed on the two supporting members 21 of a number of tire frame assemblies 2, and then transverse stirrups are put on the number of longitudinal steel bars and evenly arranged between the number of tire frame assemblies 2. The parts of the longitudinal steel bars extending out of the tire frame at both ends can finally be covered with transverse stirrups. Subsequently, the two side support arms 212 are respectively pushed to a vertical state by the two first push cylinders 213, and the free ends of the two side support arms 212 are connected to each other by the top support arm 23. At this point, the two brackets 211, the two side support arms 212 and the top support arm 23 form a rectangular frame shape.

[0039] like Figure 1 As shown, it also includes a connecting arm 24, a positioning arm 214 is vertically arranged at one end of the bracket 211 close to the right support member 22, and the tops of the two positioning arms 214 are detachably connected to the two ends of the connecting arm 24 respectively; the two positioning arms 214 and the connecting arm 24 form a concave cavity on the basis of the rectangular frame-shaped steel cage, which can enhance the structural strength of the rectangular steel cage to resist bending moment.

[0040] More specifically, Figure 1 and 3 As shown, a pad 215 is provided on the top of the bracket 211, and a plurality of first grooves 2151 are provided on the pad 215 at intervals, and a plurality of second grooves 241 are provided on the top of the connecting arm 24 at intervals; a plurality of support blocks 216 are provided on the side support arm 212 at intervals, and a third groove 2161 is provided on the top of the support block 216; a plurality of L-shaped hooks 231 are provided on the bottom of the top support arm 23 at intervals, and a fourth groove 2311 is provided on the top of the horizontal portion of the L-shaped hook 231;

[0041] The first groove 2151, the second groove 241, the third groove 2161 and the fourth groove 2311 are parallel to each other, and each of them is used to place a longitudinal steel bar, thereby realizing the positioning of a plurality of longitudinal steel bars. After the transverse stirrups are evenly arranged in place, they can be bundled.

[0042] More specifically, a plurality of auxiliary positioning members 217 are vertically spaced apart on the positioning arm 214, and the auxiliary positioning member 217 includes a support rod 2171 and a cushion block 2172. The support rod 2171 is rotatably arranged at the front side of the positioning arm 214, and the cushion block 2172 is arranged on the rotation path of the support rod 2171. The top of the cushion block 2172 abuts against the support rod 2171 to keep the support rod 2171 in a horizontal state.

[0043] When the support rod 2171 is kept in a horizontal state, the free end thereof extends a positioning arm 214 away from the right support member 22 , and a fifth groove 2173 is provided on the top of the portion of the support rod 2171 horizontally extending out of the positioning arm 214 , and the fifth groove 2173 is parallel to the fourth groove 2311 .

[0044] In specific implementation, each fifth groove 2173 can realize the positioning of a longitudinal steel bar. After placing several longitudinal steel bars in the first groove 2151, the second groove 241, the third groove 2161, the fourth groove 2311 and the fifth groove 2173 respectively, and then distributing several transverse stirrups evenly on the longitudinal steel bars, binding can begin. After binding and reinforcement, a steel cage is made, which eliminates the need for workers to manually radially position and bind each longitudinal steel bar in the traditional steel cage manufacturing process, thereby greatly improving the efficiency and quality of steel cage manufacturing.

[0045] like Figure 1 and 6 As shown, a groove 2141 is provided on the top of the positioning arm 214, and pin blocks 242 are provided on the bottom of both ends of the connecting arm 24. The two pin blocks 242 are respectively engaged with the two grooves 2141, thereby realizing a detachable connection between the connecting arm 24 and the two positioning arms 214.

[0046] More specifically, Figure 1-5 As shown, the two side arms 212 are hinged with a locking rod 25 on one side away from each other, and both ends of the top support arm 23 are provided with a locking groove 232, and the locking groove 232 is located on the rotation path of the locking rod 25;

[0047] The locking rod 25 is threadedly connected with a locking block 26 , so that after the locking rod 25 is placed in the locking groove 232 , the locking block 26 abuts against the top of the locking groove 232 , thereby connecting the side support arm 212 to the top support arm 23 .

[0048] In specific implementation, after the steel cage is tied, the locking block 26 is rotated to separate it from the locking groove 232 on the top support arm 23, until the locking rod 25 can carry the locking block 26 to rotate, and then separate from the locking groove 232, to achieve the separation of the top support arm 23 and the side support arm 212, and then control the steel cage to move slightly upward, and then move the top support arm 23 horizontally to the right to separate the L-shaped hook 231 from the longitudinal steel bar, and then move it vertically upward to remove the top support arm 23, and then control the two first push cylinders 213 to separate the two side support arms 212 from the steel cage, and then use a sling such as a gantry truck to lift the steel cage away. It should be noted that vertical movement is required during lifting. The support arm 2171 is moved upward for a certain distance to separate the steel cage from the positioning arm 214 and then moves horizontally. When the steel cage is separated from the positioning arm, the longitudinal steel bars below the auxiliary positioning member 217 will first drive the support rod 2171 in the auxiliary positioning member 217 above it to rotate upward when passing over the positioning steel bars above it, until it is separated from it. The support rod 2171 returns to a horizontal state under the action of gravity, and repeats this process until the steel cage is separated from it. When the support rod 2171 falls, it is limited by the pad 2172 and continues to maintain a horizontal state, so as to position the longitudinal bars of the next steel cage. Only the top support arm 23 needs to be manually installed and removed, which greatly improves production efficiency and safety.

[0049] Embodiment 2:

[0050] Based on the above embodiments, Figure 1-6 As shown, the right support member 22 is slidably arranged on the base 1 , and a second push cylinder 27 is arranged on the bracket 211 of the left support member 21 , and the telescopic end of the second push cylinder 27 is connected to the bracket 211 of the right support member 22 .

[0051] In specific implementation, the distance between the two brackets 211 can be controlled by the second push cylinder 27, so as to realize the manufacture of steel cages of different widths. If needed, top support arms 23 and connecting arms 24 of corresponding lengths need to be adopted. If necessary, the lengths of the two side arms 212 can also be replaced.

[0052] Embodiment three;

[0053] Based on the above two embodiments, Figure 1-7 As shown, it also includes a third push cylinder 28 and a push plate 29 . The third push cylinder 28 is vertically arranged on both brackets 211 . The telescopic end of the third push cylinder 28 is connected to the push plate 29 , and the push plate 29 moves up and down through the third push cylinder 28 .

[0054] A plurality of sixth grooves 291 are arranged at intervals on the push plate 29 , and the sixth grooves 291 are parallel to the first grooves 2151 .

[0055] During specific implementation, when the third push cylinder 28 is in a retracted state, the push plate 29 is flush with the pad 215 on the top of the bracket 211, and the sixth groove 291 corresponds one-to-one with the first groove 2151 and is in the same horizontal plane, thereby realizing auxiliary positioning of the longitudinal steel bars. When the steel cage is tied, it is difficult to lift it vertically with traditional lifting equipment, and the steel cage can be pushed upward by the third push cylinder 28, which first facilitates the separation of the top support arm 23, and then facilitates the separation of the steel cage and the two positioning arms 214, greatly improving operational safety and production efficiency.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
