Description

Technical Field

[0001] The present invention belongs to the technical field of steel bar straightening, and particularly relates to an assembled in-situ steel bar straightener. Background Technique

[0002] According to the requirements of current specifications, the pile head of the cast-in-place pile should be poured in advance, and after the concrete reaches the relevant requirements, the over-poured concrete should be removed. Specifically, the "Code for Acceptance of Construction Quality of Building Foundation Engineering" (GB50208-2002) stipulates that the pile top elevation of the cast-in-place pile should be at least 0.5 m higher than the design elevation. The "Technical Code for Building Pile Foundations" (JCJ94-2008) also makes relevant regulations on the concrete over-pouring height of different types of cast-in-place piles.

[0003] In order to ensure the pouring quality of the pile top concrete, relevant specifications have clearly required that the pile head needs to be over-poured by more than 50 cm. After the concrete reaches the design strength, the over-poured concrete is then chiseled off. To ensure work efficiency, mechanical chiseling is generally used to chisel off the over-poured concrete. However, there are a large number of relatively dense main steel bars in the over-poured part. When chiseling off this part of the concrete, most of the existing main steel bars will be disturbed, resulting in the main steel bars of the pile head being in a mess after the concrete is chiseled off. However, before the subsequent construction of the upper structure (such as the bearing platform, capping beam, etc.), these main steel bars need to be straightened to meet the engineering quality requirements.

[0004] Currently, the main steel bars of the pile head after chiseling off the concrete are mostly straightened manually directly or manually after high-temperature fire roasting. The construction technology of pipeline renewal mainly has the following problems:

[0005] (1) The straightening method after high-temperature fire roasting will affect the mechanical properties of the steel bars, thus affecting the engineering quality. In addition, a fire source needs to be prepared at the high-temperature fire roasting site, which has great safety hazards and is not easy to operate.

[0006] (2) The manual direct straightening method is mainly applicable to main steel bars with a smaller diameter. It is not easy to manually directly straighten steel bars with a diameter exceeding 20 mm, and there are great safety hazards.

[0007] (3) Most of the existing market straightening machines and patented technologies are aimed at the straightening of waste steel bar recycling (CN112170709A, CN215544508U) and the steel bar modulation technology before cutting (CN215544513U, CN215199420U, CN214417542U, and CN213530579U). The above technologies cannot straighten and repair the pile head steel bars in-situ.

[0008] (4) Most of the existing pile head steel bar straightening technologies rely on machinery such as cranes, and the design of the straightening technology is simple. There are serious safety hazards during on-site use, which does not meet the purpose of current work safety (CN112536392A, CN201427164Y, CN202910227U, CN207057520U, and CN210547652U). Summary of the Invention

[0009] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide an assembled in-situ steel bar corrector with a simple structure.

[0010] The technical solution adopted by the present invention is as follows:

[0011] An assembled in-situ steel bar corrector includes a plurality of interconnected bases. A housing and a correction groove are connected to the bases. The correction groove is located inside the housing. A pushing mechanism is installed inside the housing, and the output end of the pushing mechanism is connected to a telescopic top plate.

[0012] Place the corrector on the pile head after removing the concrete, so that the steel bar passes through the housing and is placed in the correction groove. The pushing mechanism drives the telescopic top plate to move towards the steel bar, then the telescopic top plate can press the steel bar tightly in the correction groove, and the steel bar is straightened.

[0013] The present invention can straighten the steel bar at the in-situ pile head, which is convenient for operation. According to needs, a plurality of bases can be set to straighten the corresponding number of steel bars. The present invention can be applicable to steel bars of different sizes, improving the adaptability of the device.

[0014] As a preferred solution of the present invention, the housing includes two baffles. The telescopic top plate is located between the two baffles, and the pushing mechanism is installed on one of the baffles. The two baffles can support and limit the telescopic top plate, so that when the pushing mechanism drives the telescopic top plate to act, the telescopic top plate can move along a determined path.

[0015] As a preferred solution of the present invention, the baffle is provided with a chute, and both sides of the telescopic top plate are provided with sliders, and the sliders are sleeved in the chute. When the pushing mechanism drives the telescopic top plate to move, the sliders on the telescopic top plate move in the chute, so that the telescopic top plate can only move in a straight line, ensuring that the telescopic top plate accurately straightens the steel bar.

[0016] As a preferred embodiment of the present invention, the pushing mechanism includes an electric motor mounted on the baffle. The output end of the electric motor is connected to a driving gear. On both sides of the driving gear, a gear set is provided respectively. The gear set is rotatably connected to the baffle. The output end of the gear set meshes with the driving gear. A support rod is connected between the output ends of the two gear sets. A piston rod is hinged on the support rod, and the other end of the piston rod is hinged to the telescopic top plate. When the electric motor drives the driving gear to rotate, the driving gear drives the gear set to rotate. The two gear sets on both sides rotate in the same direction and drive the support rod to move. When the support rod moves, it drives the piston rod to perform a periodic motion, so that the telescopic top plate can reciprocate linearly to fully squeeze the steel bar.

[0017] As a preferred embodiment of the present invention, the gear set includes a fixed rod rotatably connected to the baffle. A driven gear and a driving gear are respectively fixed on the fixed rod. The driving gear meshes with the driven gears of the two gear sets respectively. The support rod is rotatably connected between the two driving gears. When the driving gear drives the driven gear to rotate, the whole gear set rotates. Since the support rod is connected between the two driving gears, when the two driving gears rotate synchronously in the same direction, the support rod can be driven to perform a periodic motion.

[0018] As a preferred embodiment of the present invention, the support rod is rotatably connected in the same direction of the two driving gears. Since the two driving gears rotate synchronously in the same direction, the support rod always remains vertical when it moves. The support rod moves along a circular track, thereby driving the piston rod to perform a periodic motion.

[0019] As a preferred embodiment of the present invention, a pressure sensor is installed at the connection between the telescopic top plate and the piston rod. The pressure sensor can detect the pressure received by the telescopic top plate in real time, so as to judge the stress condition of the steel bar and facilitate the monitoring of the correction process.

[0020] As a preferred embodiment of the present invention, a socket is provided on the base, and a socket is provided on the correction groove. The socket is sleeved in the socket. Inserting the socket into the socket facilitates disassembly and assembly.

[0021] As a preferred embodiment of the present invention, a connection groove is provided on one side of the base, and a connection block is provided on the other side of the base. The connection block is sleeved in the connection groove of the adjacent base. Inserting the connection block into the connection groove of the adjacent base can achieve the rapid disassembly and assembly of the base. According to needs, the corresponding number of bases can be connected.

[0022] As a preferred embodiment of the present invention, a control console is further included, and the control console is electrically connected to the pushing mechanism. Controlling the action of the pushing mechanism through the control console is convenient for control.

[0023] The beneficial effects of the present invention are:

[0024] The corrector of the present invention is placed on the pile head after the concrete is chiseled, so that the steel bars pass through the housing and are placed in the correction groove. The pushing mechanism drives the telescopic top plate to move towards the steel bars, then the telescopic top plate can press the steel bars tightly in the correction groove, and the steel bars are straightened. The structure of the present invention is simple, easy to operate, and can straighten the steel bars at the in-situ pile head, which is convenient for operation. Description of the Drawings

Detailed Embodiment

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Accordingly, 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 claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0035] As Figure 1 and Figure 2 shown, the prefabricated in-situ steel bar straightening device of this embodiment includes a number of interconnected bases 1, a housing 2 and a straightening groove 3 are connected to the base 1, the straightening groove 3 is located inside the housing 2, and three pushing mechanisms 4 are installed inside the housing 2; the output ends of a number of pushing mechanisms 4 are all connected to a telescopic top plate 5; it also includes a console, and the console is electrically connected to the pushing mechanism 4.

[0036] Place the straightening device on the pile head after chiseling the concrete, so that the steel bar passes through the housing 2 and is placed in the straightening groove 3. The pushing mechanism 4 drives the telescopic top plate 5 to move towards the steel bar, then the telescopic top plate 5 can press the steel bar tightly in the straightening groove 3, and the steel bar is straightened.

[0037] The present invention can straighten the steel bars at the in-situ pile head, which is convenient for operation. A number of bases 1 can be set as needed to straighten the corresponding number of steel bars. The present invention can be applied to steel bars of different sizes, improving the adaptability of the device.

[0038] Specifically, as Figure 3 shown, the housing 2 includes two baffle plates 21, the telescopic top plate 5 is located between the two baffle plates 21, and three pushing mechanisms 4 are installed on one of the baffle plates 21. The two baffle plates 21 can support and limit the telescopic top plate 5, so that when the pushing mechanism 4 drives the telescopic top plate 5 to act, the telescopic top plate 5 can move along a determined path.

[0039] A panel 22 is connected between the sides of the two baffle plates 21 away from the straightening groove 3, and a power interface 23 is installed on the panel 22. Shading plates 24 are respectively connected to the upper and lower sides between the two top plates, and the shading plates 24 are located at the corresponding positions of the pushing mechanisms 4. The other positions on the upper and lower sides of the two baffle plates 21 are open to facilitate the insertion of the steel bar. The baffle plates 21 and the base 1 are connected by fixing fasteners 14, which is convenient for disassembly and assembly.

[0040] In order to ensure that the telescopic top plate 5 moves along a determined path, a number of sliding grooves 211 are provided on the baffle plate 21, and a number of sliding blocks are provided on both sides of the telescopic top plate 5, and the sliding blocks are sleeved in the sliding grooves 211. When the pushing mechanism 4 drives the telescopic top plate 5 to move, the sliding blocks on the telescopic top plate 5 move in the sliding grooves 211, so that the telescopic top plate 5 can only move in a straight line, ensuring that the telescopic top plate 5 accurately straightens the steel bar.

[0041] Specifically, as shown in Figure 4 and Figure 5 , the pushing mechanism 4 includes an electric motor 41, which is installed on the baffle 21. The output end of the electric motor 41 is connected with a driving gear 42. On both sides of the driving gear 42, there is a gear set 43 respectively. The gear set 43 is connected to the baffle 21 through a bearing. The output end of the gear set 43 meshes with the driving gear 42. A support rod 44 is connected between the output ends of the two gear sets 43. A piston rod 45 is hinged on the support rod 44, and the other end of the piston rod 45 is hinged to the telescopic top plate 5. When the electric motor 41 drives the driving gear 42 to rotate, the driving gear 42 drives the gear set 43 to rotate. The two gear sets 43 on both sides rotate in the same direction and drive the support rod 44 to move. When the support rod 44 moves, it drives the piston rod 45 to perform a periodic motion, so that the telescopic top plate 5 can reciprocate linearly to fully squeeze the steel bars.

[0042] The electric motor 41 is electrically connected to the power interface 23 and the control console. The control console can control the opening and closing of the electric motor 41 to control the steel bar straightening process.

[0043] The gear set 43 includes a fixed rod 431, which is rotatably connected to the baffle 21. A driven gear 432 and a driving gear 433 are respectively fixed on the fixed rod 431. The driving gear 42 meshes with the driven gears 432 of the two gear sets 43 respectively. The support rod 44 is rotatably connected between the two driving gears 433. When the driving gear 42 drives the driven gear 432 to rotate, the whole gear set 43 rotates. Since the support rod 44 is connected between the two driving gears 433, when the two driving gears 433 rotate synchronously and in the same direction, the support rod 44 can be driven to perform a periodic motion.

[0044] It should be noted that: the number of teeth and the diameter of the two driven gears 432 are the same, and the number of teeth and the diameter of the two driving gears 433 are the same. The two gear sets 43 are respectively arranged on the upper and lower sides of the driving gear 42. The diameters of the two driving gears are larger to expand the circular path of the support rod, so that the distance that the support rod pushes the piston rod to move is greater.

[0045] To ensure that the support rod 44 always remains vertical, the support rod 44 is rotatably connected in the same direction of the two driving gears 433. Since the two driving gears 433 rotate synchronously and in the same direction, the support rod 44 always remains vertical when it moves. The support rod 44 moves along a circular track, thereby driving the piston rod 45 to perform a periodic motion.

[0046] Furthermore, a pressure sensor is installed at the connection between the telescopic top plate 5 and the piston rod 45. The pressure sensor can detect the pressure received by the telescopic top plate 5 in real time, thereby enabling the judgment of the stress condition of the steel bar and facilitating the monitoring of the straightening process.

[0047] For the convenience of disassembly and assembly, as Figure 6 and Figure 7 shown, a socket slot 11 is provided on the base 1, and a socket 31 is provided on the straightening slot 3. The socket 31 is sleeved in the socket slot 11. Inserting the socket 31 into the socket slot 11 facilitates disassembly and assembly. A connection slot 12 is provided on one side of the base 1, and a connection block 13 is provided on the other side of the base 1. The connection block 13 is sleeved in the connection slot 12 of the adjacent base 1. Inserting the connection block 13 into the connection slot 12 of the adjacent base 1 can achieve the quick disassembly and assembly of the base 1. According to needs, the corresponding number of bases 1 can be connected.

[0048] The present invention is not limited to the above optional embodiments. Any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
