Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated component production, in particular to a large-span prestressed tendon straightening, cutting and conveying device. Background Art

[0002] Compared with ordinary concrete composite slabs, prestressed concrete composite slabs have the characteristics of high crack resistance, large bearing capacity, large span and material saving. At present, prestressed concrete composite slabs are generally produced using long-line formwork platforms, but since the long-line formwork platforms are generally about 130 meters long, the length of the prestressed tendons used is also about 120 meters. The existing prestressed tendons are generally cut by a steel bar straightening and cutting machine and stored in one place, and then transferred to the long-line formwork platform when the prestressed concrete composite slab needs to be cast. Because the prestressed tendons are long, they need to occupy a large space for storage, and it is inconvenient to transfer them, and they have deformed during the transfer process. Utility Model Content

[0003] The utility model aims to provide a large-span prestressed tendon straightening, cutting and conveying device. By arranging a prestressed tendon conveying channel and a steel bar straightening and cutting machine on the edge of a long-line formwork, the production and storage of prestressed tendons can be facilitated, solving the problem that the existing large-span prestressed tendon storage occupies a large space and is inconvenient to transfer.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A large-span prestressed tendon straightening, cutting and conveying device comprises a prestressed long-line formwork platform, a steel bar straightening and cutting machine is provided on the front side of the prestressed long-line formwork platform, and a prestressed tendon conveying channel is provided on one side of the prestressed long-line formwork platform;

[0006] The prestressed tendon conveying channel comprises a long strip substrate fixed on one side of the prestressed long line mold platform, a through groove with a lower opening extending frontward and rearward is formed on the long strip substrate, and a reversible baffle is provided at the lower end of the through groove.

[0007] Through the above technical solution, the coiled steel bar passes through the steel bar straightening and cutting machine, and the steel bar straightening and cutting machine straightens the steel bar and then the straightened steel bar enters the through groove. When the straightened steel bar reaches the set length, the steel bar straightening and cutting machine cuts the steel bar, and the cut steel bar falls onto the baffle plate;

[0008] Then the baffle turns over, and the cut steel bars (i.e. prestressed bars) automatically slide down into the slot;

[0009] Prestressed tendons can be automatically stored on one side of the long formwork platform, which can save storage space for the prestressed tendons and does not require large-scale transfer. Workers only need to move the prestressed steel bars to the formwork platform for use, making it convenient for workers to obtain materials.

[0010] The utility model is further configured as follows: the baffle is an L-shaped profile, the transverse edge of the baffle is placed below the through slot, and the vertical edge of the baffle is arranged close to the prestressed long-line mold platform;

[0011] A plurality of limit strips arranged in the front-to-back direction are fixed between the transverse side and the vertical side of the baffle, and a triangular channel is formed at the right angle between the limit strip and the baffle, and the triangular channel is inserted on the support shaft, and the support shaft is fixedly connected to the long strip substrate;

[0012] The lower end of the vertical side of the baffle is inserted into the U-shaped block, and the U-shaped block is fixed to the end of the telescopic rod of the telescopic cylinder arranged in the left and right directions, and the telescopic cylinder is fixed to the side wall of the prestressed long-line mold platform. The controller controls the telescopic cylinder and the steel bar straightening and cutting machine.

[0013] Through the above technical scheme, when the steel bar straightening and cutting machine cuts the steel bar, the controller controls the telescopic cylinder to drive the U-shaped block to approach the prestressed long-line formwork platform, and the U-shaped block drives the vertical edge of the baffle to flip and move clockwise around the support axis, and the transverse plate of the baffle also rotates clockwise to make it in an inclined state. The steel bars on the baffle can automatically slide down due to the action of gravity. When the steel bar slides down, the telescopic cylinder drives the U-shaped block to slowly return to the right, and the baffle also flips and returns counterclockwise under the action of its own gravity. The return speed of the baffle must be greater than or equal to the return speed of the U-shaped steel.

[0014] The utility model is further configured as follows: a plurality of rectangular holes arranged in the front-to-back direction are formed on the vertical side of the baffle, a connecting rod is sleeved in the rectangular hole, and two ends of the connecting rod are respectively fixedly connected to the support shaft and the long strip substrate.

[0015] Through the above technical solution, the supporting shaft is fixedly connected to the long strip substrate through the connecting rod, and the supporting shaft can limit the position of the rectangular hole, thereby preventing the baffle from moving forward and backward.

[0016] The utility model is further configured as follows: an end of the U-shaped block close to the telescopic cylinder is arranged lower than an end away from the telescopic cylinder;

[0017] One end of the U-shaped block close to the telescopic cylinder is pressed against the vertical edge of the baffle.

[0018] Through the above technical solution, the lower setting of one end of the U-shaped block can prevent the vertical edge of the baffle from interfering when flipping, thereby preventing the vertical edge of the baffle from failing to flip normally.

[0019] The utility model is further configured as follows: a plurality of material receiving seats evenly distributed linearly in the front-to-back direction are provided below the side of the long strip substrate away from the prestressed long line mold platform;

[0020] The material receiving seat comprises an oblique material receiving plate and a vertical baffle plate arranged at the lower end of the oblique material receiving plate.

[0021] Through the above technical solution, the steel bars sliding down from the baffle can automatically fall onto the receiving seat, thereby preventing the steel bars from being scattered.

[0022] The utility model is further configured as follows: a positioning plate is provided at the rear side of the through slot, the lower end of the positioning plate is inserted into two parallel supporting rods, the rear ends of the supporting rods are fixedly connected to the connecting frame, and the connecting frame is fixed to the prestressed long-line mold platform;

[0023] A compression spring is clamped between the connecting frame and the rear end of the positioning plate, and a retaining ring is fixed to the front protruding end of the support rod passing through the positioning plate;

[0024] A proximity sensor is provided on one side of the rear end of the positioning plate. The proximity sensor is electrically connected to the controller and is fixed on the prestressed long-line mold platform.

[0025] Through the above technical scheme, the steel bar straightening and cutting machine transports the steel bar backward along the through groove. When the steel bar is sprayed onto the positioning plate, the steel bar continues to drive the positioning plate to move backward. When the proximity sensor senses the positioning plate, it transmits a signal to the controller. The controller controls the steel bar straightening and cutting machine to cut the steel bar. Then the controller controls the telescopic cylinder to flip the baffle, thereby sliding the cut steel bar out to the material receiving seat. After the steel bar is separated from the positioning plate, the positioning plate automatically moves forward and resets under the action of the compression spring.

[0026] The outstanding effects of the utility model are:

[0027] Compared with the existing technology, by setting up a prestressed steel bar conveying channel and a steel bar straightening and cutting machine on the side of the long-line formwork, the production and storage of prestressed steel bars can be facilitated, solving the problem of large storage space and inconvenient transfer of existing large-span prestressed steel bars;

[0028] The cut steel bars can be automatically discharged by flipping the baffle plate, and the cut steel bars can be automatically collected by the receiving seat to prevent the prestressed bars from being scattered. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The coiled steel bar passes through the steel bar straightening and cutting machine, which straightens the steel bar and puts the straightened steel bar into the through groove. When the straightened steel bar reaches the set length, the steel bar straightening and cutting machine cuts the steel bar, and the cut steel bar falls onto the baffle.

[0042] Then the baffle turns over, and the cut steel bars automatically slide down into the slot;

[0043] Prestressed tendons can be automatically stored on one side of the long formwork platform, which can save storage space for the prestressed tendons and does not require large-scale transfer. Workers only need to move the prestressed steel bars to the formwork platform for use, making it convenient for workers to obtain materials.

[0044] The baffle 303 is an L-shaped profile, the lateral side of the baffle 303 is placed below the through slot 302, and the vertical side of the baffle 303 is arranged close to the prestressed long-line mold platform 10;

[0045] A plurality of limit strips 304 arranged in the front-to-back direction are fixed between the horizontal and vertical sides of the baffle 303, and a triangular channel 305 is formed at a right angle between the limit strips 304 and the baffle 303. The triangular channel 305 is inserted on a support shaft 306, and the support shaft 306 is fixedly connected to the long strip substrate 301;

The controller controls the telescopic cylinder and the steel bar straightening and cutting machine 20.

[0047] When the steel bar straightening and cutting machine cuts the steel bar, the controller controls the telescopic cylinder to drive the U-shaped block to approach the prestressed long-line formwork platform, and the U-shaped block drives the vertical side of the baffle to flip and move clockwise around the support axis, and the transverse plate of the baffle also rotates clockwise to make it in an inclined state. The steel bars on the baffle can automatically slide down due to the action of gravity. When the steel bar slides down, the telescopic cylinder drives the U-shaped block to slowly return to the right, and the baffle also flips and returns counterclockwise under the action of its own gravity. The return speed of the baffle must be greater than or equal to the return speed of the U-shaped steel.

[0048] A plurality of rectangular holes 309 arranged in the front-to-back direction are formed on the vertical side of the baffle 303 . A connecting rod 310 is sleeved in the rectangular hole 309 . Two ends of the connecting rod 310 are fixedly connected to the support shaft 306 and the long strip substrate 301 , respectively.

[0049] The supporting shaft is fixedly connected to the long strip substrate through the connecting rod, and the supporting shaft can limit the position of the rectangular hole to prevent the baffle from moving forward and backward.

After the rebar leaves the positioning plate, the positioning plate automatically moves forward and resets under the action of the compression spring.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
