Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and in particular to an equidistant laying steel bar trolley. Background Art

[0002] A rebar trolley is a type of construction equipment commonly used on construction sites, mainly used for laying and fixing rebar in concrete structures. Its main function is to provide a movable working platform on the construction site, allowing workers to conveniently perform tasks such as cutting, bending, tying and installing rebar.

[0003] In the process of tying and installing the circumferential main reinforcement in the tunnel, the steel bar trolley under the existing technology needs to first move the circumferential main reinforcement to the steel bar warehouse of the steel bar trolley, and then drive the steel bar to the designated installation position through the turning mechanism and the longitudinal moving mechanism. However, when tying the circumferential main reinforcement and the longitudinal reinforcement in this method, the steel bar trolley needs to place the circumferential main reinforcement in sequence. The operator cannot adjust and install the next circumferential main reinforcement until the operator completes the tying of one circumferential main reinforcement and the longitudinal reinforcement. This working method affects the overall efficiency of the project and causes unnecessary manpower loss.

[0046] See also Figure 1-16 .

[0047] The present invention provides a technical solution for an equidistantly laid steel bar trolley: an equidistantly laid steel bar trolley, used for steel bar construction in engineering tunnels, comprising a combined trolley 1 consisting of a trolley body 101, a traveling frame 102, a control bar 103 and a movable pile 104, and a steel bar warehouse 2 arranged at one end of the trolley body 101, the traveling frame 102 can drive the entire combined trolley 1 to move, and the movable pile 104 can drive the steel bar warehouse 2 to flip and translate. This is the existing technology and will not be elaborated on here. It also includes: a dispersion component 3, which is arranged at both ends of the steel bar warehouse 2, so that the steel bar warehouse 2 can evenly export its internal steel bars during the movement; a clamping component 4, which is arranged at the upper end of the trolley body 101, so as to clamp the steel bars exported from the steel bar warehouse 2; a linkage component 5, which is arranged between the trolley body 101 and the clamping component 4, so as to drive the clamping component 4 to move upward and pull the steel bars on the clamping component 4 to be equidistantly dispersed.

[0048] By setting up a combined trolley 1, a steel bar warehouse 2, a dispersing component 3, a clamping component 4 and a linkage component 5, the dispersing component 3 is used to transfer the steel bars inside the steel bar warehouse 2 to the top of the clamping component 4 at equal distances during translation, and then the clamping component 4 drives the steel bars to move upward through the cooperation between the clamping component 4 and the linkage component 5, and at the same time, the clamping component 4 is separated at equal distances, so that each steel bar on it is evenly spread out to meet the distance requirements for steel bar erection at the construction site, and the steel bars on it are positioned relative to other steel bars at the construction site by the synchronous upward movement of the clamping component 4, so that the steel bars will not shift when the construction workers are installing them, which is convenient for the construction workers to quickly complete the tying of the steel bars, and effectively improve the construction efficiency.

[0049] In one embodiment, the steel bar warehouse 2 includes a storage rack 201 rotatably arranged between the mobile piles 104 and a plurality of springs 203 and a contact pile 202 arranged inside the storage rack 201, a segmentation mechanism 204 is provided between the spring 203 and the contact pile 202, and the segmentation mechanism 204 includes: a segmentation ring 2041, which is rotatably arranged on the inner side wall of the storage rack 201, the inner side wall of the segmentation ring 2041 is provided with a segmentation groove 20411, and the outer side wall of the segmentation ring 2041 is provided with a toothed ring 20412; a contact piece 2042, a portion of the contact piece 2042 is provided. A contact plate 20421 is fixedly provided at one end thereof and is adapted to the segmented groove 20411. One side of the contact piece 2042 is fixedly provided at one end of the spring 1 203, and the other side of the contact piece 2042 is fixedly connected to the contact pile 202; a movable rack 2043 is slidably provided inside the storage rack 201; a winding roller 2044 is provided inside the storage rack 201, and the winding roller 2044 rotates coaxially with the rotating gear 303 at one end through a rotating shaft, and one end of the movable rack 2043 is sleeved on the outer wall of the winding roller 2044;

[0050] The dispersion component 3 includes a symmetrically arranged block 301 and a spring 2 302. The two ends of the spring 2 302 are respectively fixedly connected to the side wall of the block 301 and the inner wall of the storage rack 201. The storage rack 201 is internally rotated with a rotating gear 303. The upper and lower ends of the rotating gear 303 are respectively engaged with a moving plate 1 304 and a moving plate 2 305. A telescopic rod 306 is fixed between the moving plate 2 305. A resistance block 307 is fixedly provided on the opposite side of the control bar 103.

[0051] With this design, the steel bar warehouse 2 is turned over by controlling the moving pile 104, the storage rack 201 is placed horizontally, and the annular steel bars are placed into the storage rack 201. At this time, the spring 1 203 will be squeezed, and the contact pile 202 will clamp one side of the annular steel bar. The two ends of the annular steel bar will be blocked by the block 301. The steel bar warehouse 2 is turned over again to make it perpendicular to the ground. At this time, the steel bar warehouse 2 is translated to one end. When the storage rack 201 is moving, the moving plate 2 305 will contact the contact block 307 on the control bar 103. The resistance block 307 will push the movable plate 2 305 in the direction of approaching each other. At this time, the telescopic rod 306 is squeezed, and the rotating gear 303 rotates to drive the movable plate 1 304 to move in the direction of moving away from each other. The movable plate 1 304 is fixedly connected to the stopper 301, so the stopper 301 will move synchronously in the direction of moving away from each other. At this time, the stopper 301 will no longer block the steel bars inside the storage rack 201. At the same time, the rotating gear 303 at one end of the storage rack 201 will drive the movable rack 2043 through the rotating shaft. One end of the gear is wound up, and the moving rack 2043 moves in the storage rack 201. When the moving rack 2043 moves, it will mesh with the gear ring 20412 on the segmented ring 2041, thereby driving the segmented ring 2041 to rotate. When the segmented ring 2041 rotates, the contact plate 20421 inside the segmented groove 20411 that conflicts with the segmented groove 20411 will move in the stepped segmented groove 20411. When the contact plate 20421 moves to the next step segmented groove 20411, the spring 1 203 will apply a rebound force to make the contact plate 204 2 will move forward a distance and then be resisted by the side wall of the stepped segmented groove 20411. With this arrangement, each time the rotating gear 303 on one side rotates once, the resisting piece 2042 moves forward once, thereby driving the resisting pile 202 to move forward once. Each time the resisting pile 202 moves forward, the stopper 301 at the lower end will also separate once, and the steel bar will be pushed out of the storage rack 201 once. Since the resisting blocks 307 are arranged at equal intervals, the steel bars in the storage rack 201 will be continuously moved out during the process of the storage rack 201 moving toward one end.

[0052] In one embodiment, the clamping assembly 4 includes a load-bearing plate 401 arranged at the upper end of the trolley body 101, a threaded rod 402 and an auxiliary rod 403 rotatably arranged at the upper end of the load-bearing plate 401, and a plurality of clamping piles 404 are arranged between the threaded rod 402 and the auxiliary rod 403. The bottom of the clamping pile 404 is rotatably provided with a connecting bar 406 through a connecting column 407. Adjacent connecting bars 406 are rotatably connected to each other, and one end of the connecting bar 406 is rotatably connected to a connecting seat 405. One end of the connecting seat 405 is rotatably connected to the side wall of the protective pile 503.

[0053] With this design, the setting of the connecting strip 406 will cause the clamping piles 404 to be closed together when stationary. At this time, the steel bars dropped from the storage rack 201 will fall on the clamping piles 404 in sequence. When the steel bars are completely placed on the clamping piles 404, the threaded rod 402 is driven to rotate. A threaded groove threadedly connected to the threaded rod 402 is opened at the center of the clamping pile 404 away from the end of the protective pile 503, and the diameter of the hole opened at the center of the other clamping piles 404 is larger than the diameter of the threaded rod 402. Therefore, the rotation of the threaded rod 402 will only drive the farthest clamping pile 404 to move. When the farthest clamping pile 404 starts to move toward one end, since the connecting strip 406 is connected and rotated in sequence from head to tail, the remaining clamping piles 404 will gradually disperse until the adjacent spacing between them is consistent.

[0054] In one embodiment, the linkage assembly 5 includes a connecting pile 501 and a telescopic pile 502 fixedly arranged on the trolley body 101, the upper end of the telescopic pile 502 is fixedly arranged on the lower end of the load-bearing plate 401, the lower end of the telescopic pile 502 is fixedly arranged on the upper end of the trolley body 101, the upper end of the load-bearing plate 401 is fixedly provided with a protective pile 503, the interior of the telescopic pile 502 is provided with a dual-axis motor 504, one end of the output shaft of the dual-axis motor 504 is fixedly connected to the rotating rod 505, and the rotating rod 505 passes through the inner wall of the load-bearing plate 401 and the protective pile 503 and is fixedly connected to the bevel gear 1 506. One end of the threaded rod 402 passes through the inner wall of the protective pile 503 and is fixedly connected to the bevel gear 2 507 which meshes with the bevel gear 1 506. The output shaft at the other end of the dual-axis motor 504 is fixedly connected to the threaded column 509. A fixing seat 508 is fixedly provided inside the connecting pile 501. The threaded column 509 passes through the upper end of the trolley body 101 and the inner wall of the connecting pile 501.

[0055] With this design, the dual-axis motor 504 is started by the control key. The model of the dual-axis motor 504 is YZR250M2-6. One section of the output shaft of the dual-axis motor 504 will drive the threaded column 509 to rotate. The rotation of the threaded column 509 will make it move upward, thereby driving the dual-axis motor 504 to move upward. The dual-axis motor 504 is fixedly set on one side of the load-bearing plate 401, so the load-bearing plate 401 will also move upward. At this time, the telescopic pile 502 will gradually open, and the output shaft at the other end of the dual-axis motor 504 will drive the rotating rod 505 to rotate. When the rotating rod 505 rotates, it will drive the bevel gear 1 506 to rotate. The bevel gear 1 506 thereby drives the bevel gear 2 507 to rotate. The bevel gear 2 507 drives the threaded rod 402 to rotate, thereby achieving that during the upward movement of the load-bearing plate 401, the clamping piles 404 holding the steel bars are evenly dispersed, which is convenient for the operator to tie them up later.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
