Technical Field

[0001] This utility model belongs to the field of building engineering technology, and relates to a cleaning tool, and more particularly to a cleaning tool for a disc-locked steel pipe and a steel pipe plug. Background Technology

[0002] In building formwork support systems and disc-lock scaffolding construction, steel pipes are extensively used as the main load-bearing components. Due to concrete seepage, approximately 15-30% of the steel pipe ends will form concrete plugs. Traditional methods of handling this issue have the following problems: manual chiseling is inefficient, taking 20-30 minutes to process a single pipe; forceful removal leads to deformation of the steel pipe ends, resulting in an annual loss rate as high as 12-15%; and the procurement cost of specialized cleaning equipment is high. In addition, existing hydraulic jacking devices suffer from problems such as insecure clamping and poor pressure control accuracy, while rotary cleaning machines cannot handle the special structure of disc-lock steel pipes. Utility Model Content

[0003] This utility model provides a tool for cleaning disc-locked steel pipes and steel pipe plugs to overcome the defects of the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tooling for cleaning disc-lock steel pipes and pipe plugs includes a support, a disc-lock steel pipe fixing assembly, a steel pipe fixing assembly, and a top rod assembly. The disc-lock steel pipe fixing assembly includes at least one disc-lock clamping plate. The disc-lock clamping plate is fixed to the support and has a downwardly recessed disc-lock groove at its top. The disc-lock groove matches the outer wall of the steel pipe portion of the disc-lock steel pipe, allowing the steel pipe portion of the disc-lock steel pipe to be placed in the disc-lock groove, while the disc portion of the disc-lock steel pipe is locked outside the disc-lock groove. The steel pipe fixing assembly includes at least one clamping member. The clamping member is fixed to the support and can clamp the steel pipe. The placement direction of the disc-lock groove and the clamping member is on the same straight line. The top rod assembly has a telescopic top rod that can extend into the disc-lock steel pipe clamped by the disc-lock groove and the steel pipe clamped by the clamping member.

[0005] To optimize the above technical solution, the specific measures also include: Furthermore, the number of disc buckle plates is four; the spacing between the disc buckle plates matches the spacing between the discs on the disc buckle steel pipe; the number of clamping members is two; one clamping member is located between the two disc buckle plates close to the top rod, and the other clamping member is located between the two disc buckle plates away from the top rod.

[0006] Furthermore, the clamping element is a clamp.

[0007] Furthermore, the clamping member includes an upper clamp and a lower clamp; one side of the upper clamp and the lower clamp are rotatably connected, the lower clamp is fixed on the bracket, and the other side of the upper clamp and the lower clamp are connected and fixed by connecting bolts.

[0008] Furthermore, the upper and lower inner sides of the clamp are both covered with corrugated rubber pads.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, this utility model provides a tooling for cleaning disc-locked steel pipes and steel pipe plugs, including a bracket 1, a disc-locked steel pipe fixing assembly, a steel pipe fixing assembly, and a top rod assembly.

[0018] The disc-buckle steel pipe fixing assembly includes at least one disc-buckle clamping plate 2. The disc-buckle clamping plate 2 is fixed to the bracket 1, as follows: Figure 3 As shown, the top has a downwardly recessed disc buckle groove 21, which matches the outer wall of the steel pipe portion of the disc buckle steel pipe. The steel pipe portion of the disc buckle steel pipe can be placed in the disc buckle groove 21, and the disc portion of the disc buckle steel pipe is locked outside the disc buckle groove 21.

[0019] The steel pipe fixing assembly includes at least one clamping member 3. The clamping member 3 is fixed on the bracket 1 and is capable of clamping the steel pipe.

[0020] The placement directions of the disc buckle slot 21 and the clamping member 3 are on the same straight line, that is, the disc buckle steel pipe placed in the disc buckle slot 21 and the steel pipe placed in the clamping member 3 are on the same straight line.

[0021] The push rod assembly has a telescopic push rod 4, which can extend into the disc buckle steel pipe held in the disc buckle slot 21 and the steel pipe held by the clamping member 3. That is, the push rod 4 is located on one side of the disc buckle steel pipe fixing assembly and the steel pipe fixing assembly, and the telescopic direction of the push rod 4 is on the same straight line as the placement direction of the disc buckle slot 21 and the clamping member 3. When the push rod 4 is extended, it can extend into the disc buckle steel pipe held in the disc buckle slot 21 and the steel pipe held by the clamping member 3.

[0022] If the object to be cleaned is a disc-lock steel pipe, place the disc-lock steel pipe in one or more disc-lock slots 21, with its disc portion locked on the side of the disc-lock slot 21 facing the push rod 4. Then drive the push rod 4 to extend and clean the plug inside the disc-lock steel pipe. If the object to be cleaned is a steel pipe, place the steel pipe in the clamping member 3, clamp and fix it, and then drive the push rod 4 to extend and clean the plug inside the steel pipe.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, in a specific embodiment, the number of disc buckle plates 2 is four. The spacing of the disc buckle plates 2 matches the spacing of the discs on the disc buckle steel pipe, i.e., as shown... Figure 4 As shown, the four discs A1 of the disc-buckle steel pipe A are respectively secured to the disc-buckle slots 21 of the four disc-buckle plates 2. There are two clamping parts 3. One clamping part 3 is located between the two disc-buckle plates 2 closest to the top rod 4, and the other clamping part 3 is located between the two disc-buckle plates 2 furthest from the top rod 4.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, in a specific embodiment, the clamping member 3 is a clamp. Specifically, the clamping member 3 includes an upper clamp 31 and a lower clamp 32. The upper clamp 31 and the lower clamp 32 are rotatably connected on one side, the lower clamp 32 is fixed on the bracket 1, and the other side of the upper clamp 31 and the lower clamp 32 are connected and fixed by connecting bolts 33.

[0025] The upper part 31 and the lower part 32 of the clamp are both covered with corrugated rubber pads on their inner sides.

[0026] The upper part 31 of the clamp is threadedly connected to a perpendicular fastening bolt 34. Tightening the fastening bolt 34 to press it against the surface of the steel pipe provides an anti-slip function. Preferably, The lower part 32 of the clamp is fixed to the bracket 1 by mounting bolts 35, thereby enabling quick installation and disassembly.

[0027] In a preferred embodiment, the diameter of the top rod 4 is 2 mm smaller than the inner diameter of the disc-locked steel pipe / steel pipe.

[0028] In a preferred embodiment, the outer end of the push rod 4 is fixed with a tapered guide head to facilitate the push rod 4 to extend into the disc-lock steel pipe / steel pipe and to push out the plug.

[0029] like Figure 1As shown, in a specific embodiment, the push rod assembly includes an oil pump 41, a bidirectional single-connector 42, a hydraulic cylinder 43, and a cylinder push rod 44. The oil pump 41, bidirectional single-connector 42, hydraulic cylinder 43, and cylinder push rod 44 are all existing equipment and will not be described in detail. The push rod structure of the cylinder push rod 44 is a push rod 4.

[0030] The main return port 424 of the bidirectional single-connector is connected to the hydraulic cylinder outlet 432 via a pipeline. The first inlet / outlet port 421 of the bidirectional single-connector is connected to the cylinder push rod inlet port 441 via a pipeline. The second inlet / outlet port 422 of the bidirectional single-connector is connected to the cylinder push rod outlet port 442 via a pipeline. The third inlet / outlet port 423 of the bidirectional single-connector is connected to the oil pump inlet port 411 via a pipeline. The oil pump outlet port 412 is connected to the hydraulic cylinder inlet port 431 via a pipeline. Specifically, the oil pump 41 is a 4KW motor-driven electric pump, and the hydraulic cylinder 43 is a 100-type hydraulic cylinder.

[0031] During operation, the hydraulic oil flows in and out of the cylinder push rod 44 via the control lever of the bidirectional single-connector 42, thereby controlling the extension and retraction of the push rod 4 within the cylinder push rod 44. Specifically, the hydraulic oil flows from the hydraulic cylinder outlet 432 to the main return port 424 of the bidirectional single-connector, then from the third inlet / outlet port 423 of the bidirectional single-connector to the oil pump inlet port 411, and then from the oil pump outlet 412 to the hydraulic cylinder inlet port 431 to complete the pressurization and preheating process. By controlling the control lever of the bidirectional single-connector 42, pushing the control lever forward causes the hydraulic oil to flow from the hydraulic cylinder outlet 432 to the main return port 424 of the bidirectional single-connector, and then from the first inlet / outlet port 421 of the bidirectional single-connector to the cylinder push rod inlet port 441, thus allowing the hydraulic oil to enter the cylinder push rod 44, causing the push rod 4 to extend. When the control lever is pulled back, the hydraulic oil flows through the oil outlet 442 of the cylinder push rod to the second inlet / outlet 422 of the bidirectional single-connector, then through the third inlet / outlet 423 of the bidirectional single-connector to the oil pump inlet 411, and then through the oil pump outlet 412 to the hydraulic cylinder inlet 431. Thus, the hydraulic oil in the cylinder push rod 44 flows back to the hydraulic cylinder 43. As the hydraulic oil in the cylinder push rod 44 decreases, the push rod 4 retracts.

[0032] When in use, there are two operating conditions: Operating Condition 1: Cleaning the plug on the disc-lock steel pipe: The disc of the disc-lock steel pipe is placed in the disc-lock slot 21 on the support bracket 1, with the disc outside the slot 21 facing the push rod 4, ensuring that all four discs are locked outside the slot 21. At this time, the clamping member 3 is in the open state, and the steel pipe part of the disc-lock steel pipe is also placed in the clamping member 3, but the clamping member 3 does not need to be closed to clamp it. By pushing the operating lever of the two-way single-connection controller forward, the push rod 4 of the hydraulic cylinder push rod 44 extends to clean the plug. After cleaning, by pulling back the operating lever of the two-way single-connection controller, the push rod 4 of the hydraulic cylinder push rod 44 retracts, and the disc-lock steel pipe is removed and replaced with the next one.

[0033] Operating Condition 2: Cleaning the plug on the steel pipe: Place the steel pipe in the open clamping member 3 on the support 1, close the upper part 31 of the clamp, and connect and fix it with the connecting bolt 33 to ensure that both clamping members 3 clamp the steel pipe, and tighten the fastening bolt 34 to make it press against the surface of the steel pipe. Of course, at this time, the steel pipe is also placed in the disc buckle slot 21. By pushing the operating lever of the bidirectional single-connection controller forward, the push rod 4 of the hydraulic cylinder push rod 44 extends to clean the plug. After cleaning, by pulling back the operating lever of the bidirectional single-connection controller, the push rod 4 of the hydraulic cylinder push rod 44 retracts, the clamping member 3 is opened, and the steel pipe is removed to replace the next one.
