Description

Technical Field

[0001] The present application relates to the technical field of clamping tools, and more particularly, to a clamping tool for connecting a post-turbine pipe joint. Background Art

[0002] During the engine test run, the engine is installed on a test bench and connected to the engine using a corresponding supercharger exhaust pipe tool for the test run. To achieve better test run effects and the accuracy of test run results, a bent pipe needs to be installed behind the post-turbine pipe for the test run. Therefore, the original supercharger exhaust pipe tool is no longer applicable, and there is an urgent need to design a new clamping tool to help connect the bent pipe and the post-turbine pipe to improve work efficiency. Summary of the Invention

[0003] To make up for the above deficiencies, the present application provides a clamping tool for connecting a post-turbine pipe joint, aiming to improve the problems mentioned in the above background art.

[0004] The present application provides a clamping tool for connecting a post-turbine pipe joint, including an equipment assembly and a clamping assembly.

[0005] The equipment assembly includes a post-turbine pipe and a bent pipe. Flange plates are provided at the joints of the post-turbine pipe and the bent pipe, and the two flange plates are movably fitted. The clamping assembly includes a clamp A, a clamp B, a clamping member, and a self-locking member. The clamp A and the clamp B are both fixedly connected to the clamping member, the self-locking member is movably connected to the clamping member, and slots adapted to the flange plates are provided on both the clamp A and the clamp B.

[0006] In the above solution, the post-turbine pipe is connected to the engine. Hold the bent pipe and fit the two flanges of the post-turbine pipe. The clamping member controls the clamp A and the clamp B to clamp and wrap the two flange plates together, and maintain the clamping state through the self-locking member. Then connect the bent pipe to the post-turbine pipe, and the bent pipe is further connected to the test equipment to facilitate the testing of the engine. In this embodiment, one of the flange plates is provided with a conical surface. In this way, after the clamp A and the clamp B are closed, they abut against the conical surface. As the clamp A and the clamp B are further closed, the two flange plates can be closely fitted together to form a good airtight effect. In summary, the clamping assembly can conveniently help the equipment assembly to be connected, effectively improving work efficiency and saving manpower.

[0007] Further, the clamping assembly further includes two locking rings, and the two locking rings are respectively fixedly connected to the clamp A and the clamp B.

[0008] Further, the two locking rings are movably overlapped, and through holes are provided through both of the two locking rings.

[0009] In the above solution, after the clamp A and the clamp B are closed and clamped, the two locking rings also overlap, making the two through holes communicate. At this time, an external bolt can be inserted into the through holes to pin the clamp A and the clamp B together, forming a more stable fixing effect.

[0010] Further, the clamping member includes a handle A and a handle B, the handle A and the handle B are hinged, the clamp A is fixedly connected to the handle A, and the clamp B is fixedly connected to the handle B.

[0011] Further, the clamping member further includes a rocker arm, and the rocker arm is hinged to the handle B.

[0012] In the above solution, the clamp A and the clamp B are respectively fixedly connected to the handle A and the handle B, and the opening and closing of the clamp A and the clamp B are realized as the handle A and the handle B open and close.

[0013] Further, a chute is provided on the handle A, the self-locking member includes a slider, and the slider is located in the chute and is slidably connected to the handle A.

[0014] Further, the self-locking member further includes a support rod, one end of the support rod is hinged to the slider, and the other end of the support rod is hinged to the rocker arm.

[0015] Further, the self-locking member further includes a resisting rod, the resisting rod is screwed to the handle A, and the inner end of the resisting rod is movably pressed against the slider.

[0016] In the above solution, when the rocker arm and the handle A are closed, the support rod presses against the resisting rod through the slider, prompting the rocker arm to push the handle B. Thus, the handle A and the handle B achieve the closing effect, and further the clamp A and the clamp B clamp and fix the two flange plates together. At this time, continue to close the rocker arm and the handle A. When the hinge point of the support rod and the rocker arm passes the connecting line between the hinge point of the support rod and the slider and the hinge point of the handle B and the rocker arm, the handle A and the handle B start to enter the unfolding stroke. At the same time, during the process of clamping the flange plate, there is a tendency to push the handle A and the handle B apart. This tendency will prompt the hinge point of the support rod and the rocker arm to continue to try to move away from the above-mentioned connecting line. Immediately afterwards, the support rod contacts the rocker arm and is limited, preventing the attempt to move away from the connecting line. At this time, the relative positions of the handle A and the handle B are maintained, and the self-locking process is completed. Further, the screwing method of the resisting rod can adjust the position where the resisting rod contacts the slider, so as to adjust the opening angle of the handle A and the handle B in the self-locking state, and finally adjust the clamping force of the clamp A and the clamp B on the two flange plates.

[0017] Further, the clamping assembly further includes an unlocking member, and the unlocking member includes a spring. One end of the spring is fixedly connected to the handle A, and the other end of the spring is fixedly connected to the handle B.

[0018] Furthermore, the unlocking member also includes a lever, the lever is hinged to the rocker arm, and the lever is movably pressed against the support rod.

[0019] In the above scheme, in the self-locking state, the support rod is against the head end of the lever on the rocker arm, and the head end of the lever is pressed tightly against the rocker arm, causing the tail end of the lever to tilt up. At this time, the tail end of the lever is pressed down, so that the head end of the lever lifts the support rod, and the self-locking state is released. The handle A and the handle B are automatically opened under the pull of the spring. At this time, the clamp A and the clamp B are separated from the two flanges, and the turbine rear pipe and the bent pipe are naturally separated. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Among them, the clamping assembly 200 can conveniently help the equipment assembly 100 to connect, effectively improving work efficiency and saving manpower.

[0030] See also Figures 1-4 The equipment component 100 includes a vortex after-tube 110 and a curved pipe 120. Flanges 130 are provided at the connection between the vortex after-tube 110 and the curved pipe 120. The two flanges 130 are movably fitted together. The clamping component 200 includes a clamp A210, a clamp B220, a clamping piece 230 and a self-locking piece 240. The clamp A210 and the clamp B220 are fixedly connected to the clamp 230. The self-locking piece 240 is movably connected to the clamp 230. The clamp A210 and the clamp B220 are both provided with a slot that matches the flange 130. The after-vortex pipe 110 is connected to the engine, the handheld bent pipe 120 is fitted with the two flanges of the after-vortex pipe 110, the clamping piece 230 controls the clamp A210 and the clamp B220 to clamp and wrap the two flanges 130 together, and the clamping state is maintained by the self-locking piece 240, and then the bent pipe 120 is connected to the after-vortex pipe 110, and the bent pipe 120 is connected to the test equipment to facilitate the testing of the engine. In this embodiment, one of the flanges 130 is set as a conical surface, so that the clamp A210 and the clamp B220 are pressed against the conical surface after closing, and as the clamp A210 and the clamp B220 are further closed, the two flanges 130 can be tightly fitted together to form a good airtight effect. In summary, the clamping assembly 200 can conveniently help the equipment assembly 100 to connect, effectively improve work efficiency, and save manpower.

[0031] The clamping assembly 200 further includes two locking rings 250 which are respectively fixedly connected to the clamp A 210 and the clamp B 220. The two locking rings 250 overlap movably, and through holes are respectively formed through the two locking rings 250. After the clamp A 210 and the clamp B 220 are closed and clamped, the two locking rings 250 also overlap, so that the two through holes are communicated. At this time, an external bolt can be inserted into the through holes to pin the clamp A 210 and the clamp B 220 together, forming a more stable fixing effect.

[0032] Please refer to Figures 1-4 , the clamping member 230 includes a handle A 231 and a handle B 232 which are hinged. The clamp A 210 is fixedly connected to the handle A 231, and the clamp B 220 is fixedly connected to the handle B 232. The clamping member 230 further includes a rocker arm 233 which is hinged to the handle B 232. The clamp A 210 and the clamp B 220 are respectively fixedly connected to the handle A 231 and the handle B 232, and the opening and closing of the clamp A 210 and the clamp B 220 are realized along with the opening and closing of the handle A 231 and the handle B 232.

[0033] Please refer to Figures 1-4, a chute is provided on the handle A231. The self-locking member 240 includes a slider 241, and the slider 241 is located in the chute and is slidably connected to the handle A231. The self-locking member 240 further includes a support rod 242. One end of the support rod 242 is hinged to the slider 241, and the other end of the support rod 242 is hinged to the rocker arm 233. The self-locking member 240 further includes a resisting rod 243, and the resisting rod 243 is screwed to the handle A231. The inner end of the resisting rod 243 is movably pressed against the slider 241. When the rocker arm 233 and the handle A231 are closed, the support rod 242 abuts against the resisting rod 243 through the slider 241, prompting the rocker arm 233 to push against the handle B232. Thus, the handle A231 and the handle B232 achieve the closing effect, and further, the clamp A210 and the clamp B220 clamp and fix the two flanges 130 together. At this time, when the rocker arm 233 and the handle A231 are continuously closed, when the hinge point between the support rod 242 and the rocker arm 233 passes the connecting line between the hinge point between the support rod 242 and the slider 241 and the hinge point between the handle B232 and the rocker arm 233, the handle A231 and the handle B232 start to enter the unfolding stroke. At the same time, during the process of clamping the flange 130, there is a tendency to push the handle A231 and the handle B232 apart. This tendency will prompt the hinge point between the support rod 242 and the rocker arm 233 to continue to try to move away from the above-mentioned connecting line. Immediately afterwards, when the support rod 242 contacts the rocker arm 233 and is limited, preventing the attempt to move away from the connecting line. At this time, the relative positions of the handle A231 and the handle B232 are maintained, and the self-locking process is completed. Further, the screwing method of the resisting rod 243 can adjust the contact position between the resisting rod 243 and the slider 241, so as to adjust the opening angle between the handle A231 and the handle B232 in the self-locking state, and finally adjust the clamping force of the clamp A210 and the clamp B220 on the two flanges 130.

[0034] Please refer to Figures 1-4 , the clamping assembly 200 further includes an unlocking member 260. The unlocking member 260 includes a spring 261. One end of the spring 261 is fixedly connected to the handle A231, and the other end of the spring 261 is fixedly connected to the handle B232. The unlocking member 260 further includes a lever 262, and the lever 262 is hinged to the rocker arm 233. The lever 262 is movably pressed against the support rod 242. In the self-locking state, the support rod 242 abuts against the head end of the lever 262 on the rocker arm 233, pressing the head end of the lever 262 against the rocker arm 233, prompting the tail end of the lever 262 to lift. At this time, when the tail end of the lever 262 is pressed down, the head end of the lever 262 jacks up the support rod 242, disengaging from the self-locking state. The handle A231 and the handle B232 are automatically opened under the pulling of the spring 261. At this time, the clamp A210 and the clamp B220 are disengaged from the two flanges 130, and the vortex tube 110 and the elbow 120 are naturally separated.

[0035] The working principle of the clamping tool for connecting the post-vortex pipe: The post-vortex pipe 110 is connected to the engine. The hand-held bent pipe 120 is fitted to the two flanges of the post-vortex pipe 110. The rocker arm 233 and the handle A 231 are closed. The support rod 242 presses against the abutting rod 243 through the slider 241, prompting the rocker arm 233 to push the handle B 232. Thus, the handle A 231 and the handle B 232 are closed. The two flange plates 130 are clamped and wrapped together by the clamp A 210 and the clamp B 220. At this time, the rocker arm 233 and the handle A 231 are continuously closed. When the hinge point between the support rod 242 and the rocker arm 233 crosses the connecting line between the hinge point between the support rod 242 and the slider 241 and the hinge point between the handle B 232 and the rocker arm 233, the handle A 231 and the handle B 232 start to enter the unfolding stroke. At the same time, during the clamping process of the flange plate 130, there is a tendency to push the handle A 231 and the handle B 232 apart. This tendency will prompt the hinge point between the support rod 242 and the rocker arm 233 to continue to try to move away from the above-mentioned connecting line. Immediately afterwards, the support rod 242 contacts the head end of the lever 262 on the rocker arm 233, pressing the head end of the lever 262 tightly against the rocker arm 233, prompting the tail end of the lever 262 to lift. Thus, the support rod 242 is limited, preventing the attempt to move away from the connecting line. At this time, the relative positions of the handle A 231 and the handle B 232 are maintained, and the self-locking process is completed. Then, the bent pipe 120 is connected to the post-vortex pipe 110, and the bent pipe 120 is further connected to the test equipment to facilitate the testing of the engine. In this embodiment, one of the flange plates 130 is provided with a conical surface. In this way, after the clamp A 210 and the clamp B 220 are closed, they are pressed tightly against the conical surface. With the further closing of the clamp A 210 and the clamp B 220, the two flange plates 130 can be closely fitted together to form a good airtight effect. After the test is completed, the tail end of the lever 262 is pressed down, so that the head end of the lever 262 lifts the support rod 242, disengaging from the self-locking state. The handle A 231 and the handle B 232 are automatically opened under the pulling of the spring 261. At this time, the clamp A 210 and the clamp B 220 are separated from the two flange plates 130, and the post-vortex pipe 110 and the bent pipe 120 are naturally separated. In summary, the clamping assembly 200 can conveniently help the equipment assembly 100 to connect, effectively improving the work efficiency and saving manpower.

[0036] It should be noted that the specific model specifications of the post-vortex pipe 110 and the spring 261 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
