A pipe clamp handrail is arranged above the pipe clamp, and a pipe clamp baffle is arranged at the middle position inside the pipe clamp. A hydraulic jack is arranged inside the pipe clamp baffle, and a PE pipe is arranged below the pipe clamp baffle. A hydraulic jack housing is arranged on the surface of the hydraulic jack, and a jack interface is arranged above the hydraulic jack housing. Compared with the prior art, the beneficial effects of the utility model are as follows: The structure of the utility model is scientific and reasonable, and it is safe and convenient to use. In the utility model, a jack is designed at the traditional pipe clamp handrail of the hydraulic pipe clamp, which can be used when the manual pipe clamp cannot effectively flatten a faulty pipe, and it is practical, safe and convenient. In the utility model, the combination of the manual hydraulic pump and the jack is designed, which is convenient to install, does not require a power supply, and is simple to operate.

[0003] When the above pipe clamp is actually used, the structural design is unreasonable, and the pipe is easily damaged and cracked during the extrusion process. For this reason, we provide a hydraulic pipe clamping and cutting device to solve the above problems. Content of the Utility Model

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a hydraulic pipe clamping and cutting device, including a pipe clamp for hydraulic pipe cutting. The pipe clamp includes:

[0006] Relatively arranged cutting blocks;

[0007] Cutting wheels, which are movably embedded and installed at the lower ends of the cutting blocks through connecting plates, and the cutting wheels are clamped outside the pipe;

[0008] A transmission shaft, which penetrates through the outer ends of the cutting blocks;

[0009] A first swing arm and a second swing arm, which are respectively installed in cooperation at the outer ends of the transmission shaft;

[0010] A kit, which is movably sleeved on the outer ends of the first swing arm and the second swing arm;

[0011] A hydraulic rod, which is connected between the relatively arranged kits.

[0012] The utility model is further arranged such that a bearing seat is movably matched at the end of the transmission shaft, a support plate is fixed at the bottom of the bearing seat, and a bracket is fixed at the lower side of the inner end of the support plate.

[0013] The utility model is further configured such that a side plate is sleeved outside the transmission shaft near the outer end of the flow intercepting block, and the other end of the side plate is matched with the end of the flow intercepting block through a shaft member.

[0014] The utility model is further configured such that the angular variation range of the flow intercepting block relative to the support plate is 30-90°.

[0015] The utility model is further configured such that the support is of a square frame structure, and a pipeline is disposed through the middle of the support.

[0016] The utility model is further configured such that one end of the connecting kit of the first swing arm and the second swing arm is arranged in an upper and lower staggered manner.

[0021] The utility model has the following beneficial effects:

[0022] By arranging a pipe clamp to block the extrusion of the pipeline, the utility model realizes the purpose of pipeline flow interception. By driving the flow intercepting wheel and the flow intercepting block to approach each other, the extrusion of the pipeline is realized. After the flow intercepting wheel is attached to the pipeline and continues to be pressurized, while the flow intercepting wheel applies pressure to the pipeline, it rotates relative to the connecting plate, avoiding scratching and damage to the outside of the blocked pipeline. At the same time, the rotatably arranged flow intercepting wheel can apply pressure evenly, avoiding uneven depression of the pipeline due to local stress. The hydraulic rods, the kit, the first swing arm, the second swing arm and the transmission shaft form a hydraulic drive system of the flow intercepting block.

[0032] Embodiment

[0033] Please refer to Figures 1-4 , the present utility model is a hydraulic pipe-clamping flow interceptor, including a pipe clamp 1 for hydraulic interception of a pipeline. The pipe clamp 1 includes: intercepting blocks 19 arranged oppositely; an intercepting wheel 111, which is movably embedded and installed at the lower end of the intercepting block 19 through a connecting plate 110, and the intercepting wheel 111 clamps outside the pipeline; a transmission shaft, which penetrates through the outer end of the intercepting block 19; a first swing arm 15 and a second swing arm 16, which are respectively installed in cooperation with the outer end of the transmission shaft; a kit 14, which is movably sleeved on the outer ends of the first swing arm 15 and the second swing arm 16; and a hydraulic rod 17, which is connected between the relatively arranged kits 14.

[0034] Specifically, in the hydraulic pipe clamping and flow cutoff device proposed in the present application, the pipe clamping device 1 is provided to squeeze and block the pipe so as to achieve the purpose of pipe interception. The flow cutoff block 19 is used to drive the flow cutoff wheel 111 to approach each other to achieve the squeezing of the pipe. After the flow cutoff wheel 111 is fitted with the pipe, the pressure is continued. While the flow cutoff wheel 111 applies pressure to the pipe, it rotates relative to the connecting plate 110 to avoid scratching and damage to the outside of the pipe. At the same time, the rotating flow cutoff wheel 111 can apply pressure evenly to avoid uneven depression of the pipe due to local force. The hydraulic rod 17, the set 14, the swing arm 15, the swing arm 2 16 and the transmission shaft constitute the hydraulic drive system of the flow cutoff block 19. The overall structural design is reasonable, the operation is stable, and it has a certain protection effect on the pipe, thereby improving the practical value of the pipe clamping device 1.

[0035] Furthermore, a bearing seat 13 is movably provided at the end of the transmission shaft, a support plate 12 is fixed to the bottom of the bearing seat 13, a bracket 11 is fixed to the lower side of the inner end of the support plate 12, and a side plate 18 is provided on the outside of the transmission shaft near the outer end of the cut-off block 19, and the other end of the side plate 18 is matched with the end of the cut-off block 19 through a shaft, and the angle of the cut-off block 19 relative to the support plate 12 varies in the range of 30-90°.

[0036] Specifically, the bearing seat 13 is used for rotational positioning of the transmission shaft, the support plate 12 is used for installation support corresponding to the bearing seat 13, and the bracket 11 installs the separately arranged support plates 12 together. The torque transmitted from the transmission shaft to the cut-off block 19 is shared by the side plate 18, thereby realizing uniform transmission of the torque, so that the cut-off block 19 is evenly stressed.

[0037] Furthermore, the bracket 11 is a square frame structure, and a pipe is passed through the middle of the bracket 11.

[0038] Specifically, the bracket 11 serves as the base structure of the tube gripper 1. After being fixed to the external mounting surface, the tube gripper 1 is mounted and fixed. Since the bracket 11 is a square frame structure, it does not interfere with the subsequent installation of the pipe.

[0039] Furthermore, the swing arm 15 and the swing arm 2 16 are connected to one end of the kit 14 in an upper and lower staggered arrangement, and the hydraulic rod 17 is inclined.

[0040] Specifically, the position design of the swing arm 15 and the swing arm 2 16 relative to the kit 14 enables the swing arm 15 and the swing arm 2 16 to drive the corresponding connected transmission shaft to rotate in the opposite direction during the extension and retraction process of the internal piston end of the hydraulic rod 17, so that the intercepting block 19 rotating synchronously with the transmission shaft can move closer or farther synchronously, optimize the transmission efficiency, reduce the required space, and improve the compactness of the overall structure.

[0041] The intercepting wheel 111 includes a wheel body and a rubber sleeve. The rubber sleeve is arranged outside the wheel body. One end of the connecting plate 110 is fixedly connected to the side end of the intercepting block 19, and the other end of the connecting plate 110 is movably connected to the intercepting wheel 111. The lower part of the inner end of the intercepting block 19 is recessed, and the recessed area is adapted to the intercepting block 19. The rubber sleeve is provided to enhance the friction with the pipeline and ensure the stability and sealing performance of the clamping.
