[0002] In the renovation and demolition projects of heating pipeline networks, traditional pipeline fixtures mostly rely on manual operation, which has problems such as low efficiency and poor safety. Moreover, the fixtures for pipeline demolition and transfer usually adopt a fixed structure, making it difficult to adapt to pipelines with different diameters, resulting in unstable clamping or the need to frequently replace fixtures. In addition, traditional fixtures lack an automatic adjustment function, and it is easy for the clamping to fail due to changes in the gravity of the pipeline during the lifting process, and even there is a risk of pipeline slippage.

[0003] Therefore, it is necessary to provide a new auxiliary fixture for the renovation and demolition of heating pipeline networks to solve the above technical problems. Summary of the Utility Model

Specific embodiments

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0024] Please refer to Figures 1 to 4 , an auxiliary fixture for the renovation and demolition of a heat supply network pipeline provided by an embodiment of the present utility model, the auxiliary fixture for the renovation and demolition of a heat supply network pipeline includes a main beam 1, an upper side plate 2-1, a lower side plate 2-2, an intermediate connecting beam 3, an inserted steel column 4 and a clamping arm 5.

[0025] In an embodiment of the present utility model, please refer to Figures 1 to 4 , the main beam 1 is vertically arranged, a horizontally arranged cross beam 11 is fixedly welded on the top of the main beam 1, and a connecting steel plate 12 is fixedly welded on the cross beam 11. The side wall in the middle and the side wall near the bottom of the main beam 1 are respectively provided with a rotatably connected upper side plate 2-1 and a lower side plate 2-2. The upper side plate 2-1 is rotatably connected with a vertically arranged intermediate connecting beam 3, and the lower side plate 2-2 is rotatably connected with the side wall in the middle of the intermediate connecting beam 3. A horizontally arranged inserted steel column 4 is fixedly welded at the bottom of the intermediate connecting beam 3, and the intermediate connecting beam 3 and the inserted steel column 4 form an L-shaped structure. A clamping arm 5 is fixedly welded on the lower side plate 2-2, and a rotatably connected V-shaped clamping steel plate 6 is installed on the clamping arm 5. Specifically, a rotating shaft 61 is fixedly installed on the V-shaped clamping steel plate 6, and the rotating shaft 61 is rotatably installed at the connecting end of the clamping arm 5.

[0026] Among them, when installing this fixture, an excavator is used as the power source, and the connecting steel plate 12 is fixedly installed at the output end of the excavator boom through bolts.

[0027] It should be noted that: when the heat supply network pipeline is demolished and transferred, due to the provision of the auxiliary part 8, the clamping arm 5 is in an upward-tilting mode (as shown in the appendix Figure 1As shown in the figure, insert the steel column 4 into the pipe from the pipe opening, and then lift the fixture. After that, the inserted steel column 4 abuts against the upper arc surface of the inner cavity of the pipe. During the lifting process of the main beam 1, the clamping arm 5 is driven by the lower side plate 2-2 to deflect downward around the intermediate connecting beam 3 until the V-shaped clamping steel plate 6 firmly abuts against the outer wall of the pipe. Therefore, the V-shaped clamping steel plate 6 and the inserted steel column 4 cooperate with each other to quickly clamp the pipe. Combined with the power source drive of the excavator, manual intervention is reduced, the operation efficiency is significantly improved, and it is suitable for heating network pipes with various conventional diameters.

[0028] Furthermore, a rubber plate 41 is fixedly embedded on the upper column surface of the inserted steel column 4, and a rubber pad 62 is fixedly embedded on the inner plate wall of the V-shaped clamping steel plate 6. The added rubber plate 41 and rubber pad 62 avoid the hidden danger of causing clamping marks on the pipe surface.

[0029] Furthermore, a mating steel plate 42 is fixedly welded on the intermediate connecting beam 3, and the mating steel plate 42 is located above the connection of the inserted steel column 4, so that the mating steel plate 42 can abut against the pipe opening, and cooperate with the V-shaped clamping steel plate 6 to make the pipe more stable during clamping and hoisting.

[0030] It should be noted that: this fixture clamps and transports pipes of different lengths according to the size of the excavator used by the construction unit (in order to improve safety, the maximum length of the clamped and transferred pipe should not exceed 7 meters).

[0031] In this embodiment, a limiting steel plate 7 is fixedly welded on the side wall of the main beam 1 and is inclined upward. The limiting steel plate 7 restricts the upward deflection angle of the upper side plate 2-1 along the main beam 1, so that the minimum distance between the main beam 1 and the intermediate connecting beam 3 can be controlled.

[0032] In the embodiment of the present utility model, please refer to Figures 1 to 4 , an auxiliary member 8 is arranged between the upper side plate 2-1 and the main beam 1. The auxiliary member 8 includes a sleeve 81, a sliding rod 82 is inserted and slidably connected in the sleeve 81, and an A collar 83 is fixedly welded at the tail of the sleeve 81. A socketed A rod 84 is inserted and rotatably connected on the A collar 83, and the socketed A rod 84 is fixedly welded on the upper side plate 2-1. A B collar 85 is fixedly welded at the head of the sliding rod 82, and a socketed B rod 87 is inserted and rotatably connected on the B collar 85. A fixed steel block 86 is fixedly welded at the head of the socketed B rod 87, and the fixed steel block 86 is fixedly welded on the beam wall of the main beam 1 near the bottom. A spring 88 is installed in the sleeve 81. One end of the spring 88 is fixedly connected to the inserted end of the sliding rod 82, and the other end of the spring 88 is fixedly connected to the inner wall of the sleeve 81.

[0033] It should be noted that when the fixture is not in use, under the action of the elastic force of the spring 88, the sleeve 81 cooperates with the sliding rod 82 to push the upper side plate 2-1 to deflect upward (until it abuts against the limiting steel plate 7), driving the clamping arms 5 on the intermediate connecting beam 3 to open. When clamping a pipeline, the inserted steel column 4 is affected by the gravity of the pipeline. At the same time, during the hoisting process of the main beam 1, the sleeve 81 and the sliding rod 82 are driven to contract and compress the spring 88, so that the clamping arms 5 deflect downward around the intermediate connecting beam 3 until the V-shaped clamping steel plate 6 firmly abuts against the outer wall of the pipeline.

[0034] Among them, the spring 88 can be replaced with a fatigue-resistant polyurethane buffer or a hydraulic damper as needed to extend the service life.

[0035] In this embodiment: The auxiliary part 8 can also be replaced with a cylinder or a hydraulic cylinder to expand the applicability of the fixture under different working conditions and at the same time reduce the maintenance difficulty.

[0036] Among them, the surface of this fixture can be coated with an anti-rust paint as needed (the specific paint is not limited here), so as to improve the service life of the fixture.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
