Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe recovery fences, in particular to a recovery fence used for recovering steel pipes. Background Art

[0002] In recent years, with the continuous expansion of the scale of engineering construction in China, the demand for steel pipes in various construction projects has also shown a significant growth trend. Steel pipes have been widely used in construction projects due to their convenient construction and reusable characteristics, effectively reducing construction costs. However, with the increase in the use of steel pipes, the problem of their recycling management has become increasingly prominent. In actual construction sites, most steel pipes are used in a rental manner. After use, the recycling process often lacks effective organization and management. Steel pipes are randomly stacked, which not only occupies a large amount of space, but also increases the difficulty of management. Especially in the bundling and transportation process, due to the tubular structure characteristics of steel pipes, the bundled steel pipe bundles are prone to movement and shrinkage, and even cause the steel pipes to fall off, which not only affects the construction efficiency, but is also likely to cause safety accidents and pose a threat to personnel safety. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a recycling fence for recycling steel pipes, which is used to solve the above problems.

[0004] The utility model is achieved in this way:

[0005] A recycling fence for recycling steel pipes, comprising a steel frame recycling fence, the steel frame recycling fence having a base and a guardrail arranged on the base, the left and right sides of the guardrail having cross beams, the front side of the guardrail being an opening, the rear side of the guardrail being provided with a back plate, two mounting parts welded on the base by channel steel, a folding clamp being provided on the mounting part, the folding clamp comprising a mounting seat arranged on the top of the mounting part, two grippers being hinged on the mounting seat, a hydraulic linkage rod being provided inside the mounting seat and being hinged to the two grippers, and when the two grippers are fully unfolded, the top of the grippers abuts against the cross beam.

[0006] In an embodiment of the utility model, the mounting base includes a fixing plate, which is arranged on the top of the mounting portion, and base side plates are arranged at the front and rear side edges of the top of the fixing plate, and a sealing plate is arranged on the top of the base side plates.

[0007] In an embodiment of the present invention, the top of the sealing plate is an arc-shaped surface.

[0008] In an embodiment of the utility model, a plurality of rubber strips are adhered to the top of the sealing plate along the front-to-back direction.

[0009] In an embodiment of the utility model, hinge shaft holes are provided at the left and right edges of the front side of the base side plate, and the gripper is fixed at any two opposite hinge shaft holes through a hinge shaft.

[0010] In an embodiment of the utility model, the hydraulic linkage rod includes a hydraulic rod and a transmission rod, one end of the transmission rod is hinged to the output shaft of the hydraulic rod, and its hinge is hinged to one of the grippers, and the other ends of the hydraulic rod and the transmission rod are hinged to the other gripper.

[0011] In an embodiment of the utility model, anti-collision rubbers are arranged at opposite positions of the two cross beams, and when the retracting clamp is fully opened, the top of the retracting clamp contacts the anti-collision rubbers.

[0012] The beneficial effects of the utility model are as follows: through the coordinated use of the gripper and the hydraulic linkage rod, the steel pipes can be stacked quickly and efficiently, which simplifies the traditional cumbersome recycling process, not only improves work efficiency but also reduces labor costs; secondly, the anti-collision rubber effectively buffers the collision between the steel pipe and the recycling bar, avoiding deformation and damage caused by the collision.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] 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 claimed invention, 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 the field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-3As shown, the utility model provides a recycling fence for recycling steel pipes, including a steel frame recycling fence 10, which is composed of a plurality of channel steels and columns welded together, and the steel frame recycling fence 10 has a base 11, and the base 11 is a guardrail 12 part, and the left and right sides of the guardrail 12 are provided with cross beams 121, and the front side of the guardrail 12 is an opening 123, which is convenient for placing the steel pipe, and the back side of the guardrail 12 is provided with a back plate 122, and two mounting parts 111 are welded on the base 11 through channel steel, and these mounting parts 111 are provided with folding clamps 20, and the folding clamps 20 include a mounting seat 21 arranged on the top of the mounting part 111, and two grippers 22 are hinged on the mounting seat 21, and a hydraulic linkage rod 24 is also arranged inside the mounting seat 21, which is connected with the mounting seat 21. The two grippers 22 are hinged. When the recycling bar is filled with steel pipes, the two grippers 22 can be driven to close through the hydraulic connecting rod 24, so that the contact between the steel pipes is tighter, which greatly simplifies the subsequent binding work. It is worth mentioning that when the two grippers 22 are fully unfolded, their tops form a conflict with the crossbeam 121. In the process of recycling steel pipes, there is not only manual transportation, but also lifting and transportation by equipment such as tower cranes. Moreover, during the lifting process, they can only be lifted in from the top of the recycling bar. The conflict between the grippers 22 and the crossbeam 121 not only prevents the steel pipes from falling into the gap between the retracting clamp 20 and the steel frame recycling bar 10 during the lifting process, reducing additional work tasks, but also provides a guiding function for the falling of the steel pipes, making the entire recycling process smoother and more efficient.

[0023] As a preferred embodiment, anti-collision rubber is provided at the opposite positions of the two beams 121. When the folding clamp 20 is fully opened, its top will collide with the anti-collision rubber. This design avoids the deformation problem caused by frequent collisions between the folding clamp 20 and the beam 121 during use. Long-term use, especially frequent collisions, often cause metal parts to deform, thereby affecting their normal functions. The addition of anti-collision rubber effectively buffers this collision force and protects the structural integrity of the folding clamp 20 and the beam 121. In addition, the anti-collision rubber also plays the role of protecting the coating. Once the paint coating on the surface of the metal part is hit, it is easy to fall off, which not only affects the appearance of the part, but more importantly, it may cause the metal to be exposed to the air, thereby accelerating the rusting process. Rust will further weaken the structural strength of the part and ultimately affect the use of the recycling bar. Therefore, the provision of the anti-collision rubber not only protects the coating, but also indirectly prevents the occurrence of rust problems.

[0024] like Figure 3-4 As shown, the mounting base 21 includes a fixing plate 211 , which is disposed on the top of the mounting portion 111 , a base side plate 212 is disposed at the front and rear side edges of the top of the fixing plate 211 , and a sealing plate 213 is disposed on the top of the base side plate 212 .

[0025] Among them, the top of the sealing plate 213 is an arc-shaped surface, and the arc-shaped surface has a natural gathering effect. When the steel pipe is placed for recycling, the arc-shaped surface can effectively guide the steel pipe to gather towards the center, so that it has a certain stability in the initial stage of stacking. The ultimate purpose of recycling the steel pipe is to bundle it for transportation, and the most ideal cross-sectional shape after bundling is a circle. The circle shows excellent stability during transportation, and traditional stacking methods often find it difficult to achieve this effect. The utility model achieves that the steel pipe can naturally form a stacking shape close to a circle in the initial stage of recycling through the cooperation of the arc-shaped sealing plate 213 and the arc-shaped gripper 22.

[0026] As a preferred embodiment, in order to prevent the steel pipes from shaking during the initial stacking and affecting the stability of the subsequent stacking, a number of rubber strips are adhered to the top of the sealing plate 213 along the front-to-back direction. These rubber strips are soft and can effectively limit the movement of the steel pipes, ensuring their stable stacking in the recycling bin, laying a solid foundation for subsequent transportation work.

[0027] like Figure 3-5 As shown, hinge shaft holes 2121 are opened at the left and right edges of the front side of the base side plate 212, and the gripper 22 is fixed at any two opposite hinge shaft holes 2121 through the hinge shaft 23.

[0028] Furthermore, the hydraulic linkage rod 24 includes a hydraulic rod 241 and a transmission rod 242. One end of the transmission rod 242 is hinged to the output shaft of the hydraulic rod 241, and its hinge is hinged to one of the grippers 22. The other ends of the hydraulic rod 241 and the transmission rod 242 are hinged to the other gripper 22. When the hydraulic rod 241 is extended or retracted, the two grippers 22 can be rotated and retracted along the hinge axis 23.

[0029] As a preferred embodiment, a full load mark is provided on the upper side of the inner side of the folding clamp 20. When the folding clamp 20 is filled with steel pipes in a fully opened state, if the hydraulic rod 241 continues to be controlled to fold the two grippers 22, the top steel pipe may be squeezed out of the recycling fence. At this time, the full load mark can play a key role, providing the staff with a clear basis for judgment, ensuring that the folding action can be stopped in time when the steel pipe is fully loaded, avoiding the steel pipe from falling or being damaged, thereby improving the safety and efficiency of the use of the recycling fence.

[0030] Specifically, the working principle of the recycling bar for recycling steel pipes is as follows: before use, the staff controls the hydraulic rod 241 to open the two grippers 22 to ensure that the grippers 22 are in contact with the crossbeam 121 to provide stable support for the placement of the steel pipes. Subsequently, the steel pipes are placed one by one inside the two retracting clamps 20. As the steel pipes are continuously stacked, when the full load mark scale is reached, it indicates that the recycling bar is fully loaded. At this time, the staff operates the hydraulic rod 241 again to gradually retract the two grippers 22. As the grippers 22 are retracted, The steel pipes are naturally stacked into steel pipe bundles with a cross-section that is approximately circular. This shape of steel pipe bundle is not only convenient for subsequent bundling operations, but also more stable after bundling, effectively reducing the risk of deformation or falling caused by road bumps during transportation. The above structure solves the problem in the prior art that due to the tubular structure characteristics of the steel pipes, the steel pipe bundles are prone to move and shrink during transportation after bundling the randomly stacked steel pipes, and may even cause the steel pipes to fall off, affecting construction efficiency and more likely to cause safety accidents, posing a threat to personnel safety.

[0031] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
