Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and in particular relates to a steel bar removal device. Background Art

[0002] During the concrete road construction process, side formwork is an important part of ensuring the quality and safety of the road surface. As a formwork structure set along the side of the road, it not only provides a solid support framework for concrete pouring operations, effectively curbs the potential collapse or deformation of concrete during the pouring process, but also ensures that the final road surface edge reaches a highly flat standard.

[0003] In order to improve the stability and bearing capacity of the side formwork, the existing technology usually reinforces the side formwork by embedding steel bars deep into the pavement foundation. When these steel bars complete their reinforcement task, they need to be removed. The currently commonly used method is for workers to repeatedly hit the left and right sides of the steel bars with a hammer to loosen the steel bars in the foundation, and then pull out the steel bars manually or with the help of tools such as pliers. This method is not only labor-intensive and has low construction efficiency, but also easily causes the steel bars to be severely bent, making them unreusable. Utility Model Content

[0004] The purpose of the utility model is to provide a steel bar removal device to solve the problems existing in the above-mentioned prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A steel bar removal device includes a support, a mounting plate with an end hinged on the support, two clamping members arranged symmetrically and located below the mounting plate, a rotating shaft that rotates through the mounting plate, a rotating rod vertically connected to one end of the rotating shaft, and a transmission member fixedly connected to the other end of the rotating shaft and connected to two groups of the clamping members. When the rotating shaft rotates, the two clamping members are driven closer to or away from each other through the two transmission members.

[0007] Preferably, the transmission member includes: a first connecting rod fixedly connected to the rotating shaft in the middle, a second connecting rod hinged at both ends of the first connecting rod, and a vertical rod hinged at the other end of the two second connecting rods, the vertical rod is horizontally slidably connected to the mounting plate, and the clamping member is hinged at the two ends of the vertical rod.

[0008] Preferably, a horizontal sliding groove is provided on the mounting plate, and a sliding block slidably connected to the horizontal sliding groove is provided on the side wall of the vertical rod.

[0009] Preferably, the clamping member includes: a clamping plate, an ear plate arranged on the opposite sides of the two clamping plates and hinged to the transmission member, and a rubber anti-slip pad arranged on the opposite sides of the two clamping plates, and the rubber anti-slip pad is provided with tooth-shaped corrugations.

[0010] Preferably, the mounting plate is hinged to the support via a connecting member, and the connecting member comprises: a swivel seat rotatably connected to the support, and a hinge seat fixedly arranged at the upper end of the swivel seat, and the end of the mounting plate is hinged to the hinge seat.

[0011] Preferably, a rubber anti-slip pad is provided at the bottom end of the support.

[0012] Preferably, the rotating rod includes: a fixing rod with a hollow interior and a bottom end vertically connected to the rotating shaft; and an adjusting rod with a bottom end extending into the fixing rod and threadedly connected to the fixing rod.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The utility model drives the rotating shaft to rotate by rotating the rotating rod, and then transmits the rotating motion to the clamping member through the transmission member, so that the two clamping members firmly clamp the steel bar. After clamping the steel bar, the rotating rod continues to rotate, so that the mounting plate rotates with the hinge point with the support as the fulcrum, providing an upward force for the clamping member and the clamped steel bar, so that the steel bar is gradually pulled out from the road foundation. The device uses the lever principle to amplify the operating force and realizes the rapid and stable clamping and extraction of the steel bar through mechanized operation, which greatly improves the construction efficiency, reduces the labor intensity of the operator, effectively avoids the problem of steel bar bending caused by traditional extraction methods, and increases the reuse rate of steel bars;

[0015] 2. The utility model drives the first connecting rod to rotate on the rotating shaft, thereby causing the second connecting rod to swing around the hinge point. The vertical rod slides horizontally on the mounting block under the action of the second connecting rod, thereby causing the clamping piece hinged at the end of the vertical rod to open and close in the horizontal direction, ultimately achieving accurate, fast and stable clamping of the steel bar, avoiding the problem of steel bar falling off or sliding due to unstable clamping, ensuring the smooth removal process, and being applicable to the removal of steel bars of different sizes and materials, with strong versatility and flexibility.

[0016] 3. The utility model provides a rubber anti-skid pad with tooth-shaped corrugations on the inner side of the clamping plate, which effectively improves the friction and bite force between the clamping piece and the steel bar, ensures the stability of the steel bar during extraction, and avoids operational failures caused by sliding or falling off. The provision of the rubber anti-skid pad can also reduce damage to the steel bar surface during the clamping process to a certain extent, protecting the integrity and service life of the steel bar.

[0017] 4. The utility model greatly improves the convenience and flexibility of the steel bar extraction device by rotatably setting a swivel seat on the support, so that the operator can adjust its direction and angle by rotating the mounting plate without moving the entire device, thereby conveniently extracting nearby steel bars. This not only saves the time and manpower required to move the device, but also can adapt to the needs of extracting steel bars in different directions and angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] like Figure 1 - Figure 2 As shown, a steel bar removal device includes a support 1, a mounting plate 2 hinged at one end to the support 1, two clamping members 3 symmetrically arranged and located below the mounting plate 2, a rotating shaft 4 rotating through the mounting plate 2, a rotating rod 5 vertically connected to one end of the rotating shaft 4, and a transmission member 6 fixedly connected to the other end of the rotating shaft 4 and connected to the two groups of the clamping members 3. When the rotating shaft 4 rotates, the two clamping members 3 are driven to move closer to or away from each other through the two transmission members 6.

[0030] It should be noted that: in order to further ensure the stability of the device during use, the construction personnel can step on the support 1 to prevent the support 1 from sliding or moving, thereby further ensuring the smooth progress of the removal work;

[0031] When it is necessary to pull out the steel bar, the user first rotates the rotating rod 5 to drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, the rotating motion is converted into the two clamping parts 3 closer to each other through the transmission part 6, thereby achieving a stable clamping of the steel bar. After the steel bar is firmly clamped, the operator continues to rotate the rotating rod 5. At this time, the mounting plate 2 rotates with the hinge point with the support 1 as the fulcrum. This rotating action provides an upward force for the clamped steel bar through the transmission part 6 and the clamping part 3. This force is generated by the lever principle, that is, a larger pulling force is generated on a longer lever arm through a smaller rotating force. The pulling force is sufficient to overcome the resistance of the steel bar in the pavement foundation, thereby pulling the steel bar out of the foundation. The entire pulling process is mechanized, which is not only fast but also uniform in force. It effectively avoids the problem of steel bar bending caused by traditional pulling methods and improves the reuse rate of steel bars. The device realizes fast and stable clamping and pulling out of steel bars, greatly improves construction efficiency and reduces the labor intensity of operators.

[0032] like Figure 2 As shown, the transmission member 6 includes: a first connecting rod 7 fixedly connected to the rotating shaft 4 in the middle, a second connecting rod 8 hinged at both ends of the first connecting rod 7, and a vertical rod 9 hinged at the other end of the two second connecting rods 8, the vertical rod 9 is horizontally slidably connected to the mounting plate 2, and the clamping member 3 is hinged at the two ends of the vertical rod 9.

[0033] A horizontal sliding groove 10 is provided on the mounting plate 2 , and a sliding block 11 slidably connected to the horizontal sliding groove 10 is provided on the side wall of the vertical rod 9 .

[0034] The working principle of the transmission part 6 in this device is as follows: when the construction worker rotates the rotating rod 5, it drives the rotating shaft 4 vertically connected to it to rotate, and the first connecting rod 7 fixed on the rotating shaft 4 rotates together with the rotating shaft 4, thereby driving the two second connecting rods 8 hinged at both ends of the first connecting rod 7 to swing around the hinge point, thereby driving the vertical rod 9 hinged at the other end of the two second connecting rods 8 to move in the horizontal direction, and the slider 11 on the side wall of the vertical rod 9 is slidably connected to the horizontal slide groove 10 on the mounting plate 2, ensuring the stable movement of the vertical rod 9 in the horizontal direction. As the vertical rod 9 moves in the horizontal direction, the clamping parts 3 hinged at the ends of the vertical rod 9 approach or move away from each other, ultimately achieving accurate, fast and stable clamping of the steel bars, avoiding the problem of steel bars falling off or sliding due to unstable clamping, ensuring the smooth removal process, and can be applied to steel bar removal operations of different sizes and materials, with strong versatility and flexibility.

[0035] like Figure 2As shown, the clamping member 3 includes: a clamping plate 12, an ear plate 14 arranged on the opposite sides of the two clamping plates 12 and hinged to the transmission member 6, and a rubber anti-slip pad 13 arranged on the opposite sides of the two clamping plates 12, and the rubber anti-slip pad 13 is provided with a tooth-shaped corrugation.

[0036] It should be noted that in practice, the clamping plates 12 can be made of materials with sufficient strength and rigidity, such as steel or alloy; rubber anti-slip pads 13 with serrated corrugations are provided on the opposite sides of the two clamping plates 12. The rubber anti-slip pads 13 provide good friction performance, and the serrated corrugations increase the contact area and bite force with the surface of the steel bar, thereby ensuring that the steel bar can be firmly clamped during the removal process and will not fail due to sliding or falling off. In addition, the rubber anti-slip pads 13 can also reduce the damage to the surface of the steel bar during the clamping process to a certain extent, thereby protecting the integrity and service life of the steel bar.

[0037] like Figure 1 As shown, the mounting plate 2 is hinged to the support 1 through a connecting member, and the connecting member includes: a swivel seat 15 rotatably connected to the support 1, and a hinge seat 16 fixedly arranged at the upper end of the swivel seat 15, and the end of the mounting plate 2 is hinged to the hinge seat 16; a rubber anti-slip pad 13 is provided at the bottom end of the support 1.

[0038] The setting of the swivel seat 15 improves the convenience and flexibility of the steel bar extraction device. The mounting plate 2 is hinged to the support 1 through the swivel seat 15. The operator can adjust its direction and angle by rotating the mounting plate 2 without moving the position of the entire device, thereby conveniently extracting the nearby steel bars; the rubber anti-slip pad 13 can increase the friction between the support 1 and the supporting surface to prevent the support 1 from sliding or shifting during the extraction process. When the construction worker rotates the rotating rod 5 to drive the mounting plate 2 to rotate with the hinge point as the fulcrum, it further drives the clamping member 3 and the clamped steel bars to rise together, thereby realizing the extraction of the steel bars, improving construction efficiency, and reducing the labor intensity of the operator.

[0039] In order to improve the convenience of the device and make it easier to transport and store, the rotating rod 5 includes: a fixed rod 17 with a hollow interior and a bottom end vertically connected to the rotating shaft 4, and an adjusting rod 18 with a bottom end extending into the fixed rod 17 and threadedly connected to the fixed rod 17.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described with reference to the preferred embodiments of the present invention, those skilled in the art should understand that various changes can be made in form and details without departing from the spirit and scope of the present invention as defined in the appended claims.
