Description

Technical Field

[0001] The utility model relates to the technical field of engine detection equipment, in particular to a bench support device for an engine exhaust system. Background Art

[0002] The exhaust system is subjected to very complex loads during the operation of the engine, including exhaust pulses and exhaust pipe vibrations. During the durability test of components on the bench, the exhaust system and mounting bolts often break due to the exhaust pipe not being properly fixed. If not discovered in time, it will further cause the early failure of other connected components, seriously affecting the effectiveness of the durability assessment. In the prior art, a support device is often used to support and fix the exhaust pipe. The support device includes a base, a support rod with adjustable height, and a U-shaped support rod at the top of the support rod. The U-shaped support rod supports the exhaust pipe by adjusting the height of the support rod. The support device has a high demand for space around the exhaust pipe, is difficult to install and arrange, and is prone to interference. At the same time, the base is difficult to fix. When the height of the support rod is adjusted, the U-shaped support rod is difficult to accurately fit the lower end of the exhaust pipe, causing the support device to loosen, fall off, and other problems, affecting the experimental results. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an engine exhaust system bench support device which is not subject to the exhaust system space requirement and can stably support the exhaust pipeline.

[0004] In order to solve the above technical problems, the utility model includes a base, and its structural features are: a vertical telescopic rod capable of adjusting the height is provided on the base, a horizontally arranged transverse telescopic rod is provided on the upper end of the vertical telescopic rod, a fixing device capable of fixing the exhaust pipeline is provided on the transverse telescopic rod, the transverse telescopic rod can adjust the horizontal position of the fixing device, and a fine-tuning device capable of fine-tuning the height of the transverse telescopic rod is provided on the vertical telescopic rod.

[0005] After adopting the above structure, the height of the fixing device is adjusted by the vertical telescopic rod, and the horizontal position of the fixing device is adjusted by the transverse telescopic rod. After the fixing device is adjusted to the approximate position, the exhaust pipe is fixed by the fixing device, and the height of the transverse telescopic rod is fine-tuned by the fine-tuning device. Then, the height of the fixing device is fine-tuned, so that the fixing device can completely restrain the exhaust pipe, ensuring the stability of the fixed exhaust pipe. At the same time, the position in the vertical and horizontal directions can be flexibly adjusted, and it is not limited by the space of the bench exhaust pipe, and has strong applicability.

[0006] The vertical telescopic rod comprises a fixed rod fixedly connected to the base and a movable rod inserted in the fixed rod. The movable rod can move up and down along the inner wall of the fixed rod. The upper end of the fixed rod is provided with a locking device that can fix the position of the movable rod.

[0007] The top end of the fixed rod is provided with a position limiting observation window for observing the movable rod inserted in the fixed rod.

[0008] After adopting the above structure, the movable rod slides in the fixed rod, the movable rod moves upward, the vertical telescopic rod becomes higher, and the transverse telescopic rod located at the upper end of the vertical telescopic rod moves upward, thereby driving the position of the fixing device to move upward, and the position of the movable rod is observed through the limit observation window at the top of the fixed rod. When the movable rod is seen to be at the tail end, avoid continuing to move upward, causing the movable rod to fall off the fixed rod. When it moves to a suitable position, the position of the movable rod is fixed by the locking device, so that the position of the movable rod is locked, and then the height of the fixing device is determined, which is convenient for jumping the height of the fixing device, and is convenient for adapting to the needs of different heights, thereby improving the implementation efficiency.

[0009] The transverse telescopic rod includes a left fixed rod and a right movable rod 32 inserted in the left fixed rod, and the right movable rod 32 can move left and right along the inner wall of the left fixed rod. The left fixed rod and the right movable rod are both square tubes. The left fixed rod is provided with a locking device that can fix the position of the right movable rod 32. The right movable rod 32 moves left and right in the left fixed rod, thereby driving the change of the horizontal position of the fixing device to adapt to the space around the exhaust pipe and facilitate the arrangement of the fixing device. At the same time, the square tube prevents the right movable rod from rotating in the fixed rod, avoids the rotation of the fixing device, and ensures the stability of the fixing device. After moving to the appropriate position, the position of the right movable rod 32 is fixed by the locking device, and then the position of the fixing device is locked, thereby ensuring the stability of the supporting device.

[0010] The fine-tuning device includes a fine-tuning rod inserted at the top of a movable rod, a thread is provided at the bottom of the outer edge of the fine-tuning rod, an adjusting nut threadedly connected to the thread at the bottom end of the fine-tuning rod is installed at the top of the movable rod, and a locking device capable of fixing the position of the fine-tuning rod is provided at the top of the movable rod. By rotating the adjusting nut, the adjusting nut and the thread at the lower end of the fine-tuning rod rotate relative to each other, thereby converting the rotational motion into linear motion, driving the fine-tuning rod to move up and down, and fine-tuning the height of the lateral telescopic rod and the fixing device at the top, so that the fixing device can fit the exhaust pipe more closely, thereby ensuring the stability of the exhaust pipe fixation.

[0011] A handle is fixedly connected to the outer edge of the adjusting nut, and the handle facilitates the rotation of the adjusting nut, making it easy for operators to adjust the fine-tuning device, thereby improving efficiency.

[0012] The locking device includes a locking tube, which can reduce the inner diameter and clamp the internal pipeline of the locking tube. An axial opening is provided on the side wall of the locking tube, and both ends of the opening are provided with clamping plates extending outward. The two clamping plates are provided with bolts and nuts that can close / move the distance between the two clamping plates. The distance between the clamping plates is tightened by the bolts and nuts, and then the distance between the two side walls of the opening is tightened, thereby shortening the inner diameter of the locking tube and making the inner diameter of the locking tube fit the internal pipeline. As the clamping plates are tightened, the locking device of the vertical adjustment rod clamps the movable rod, the locking device in the fine-tuning device clamps the fine-tuning rod, and the locking device of the lateral adjustment rod clamps the right moving rod 32. Through the three locking devices, the vertical and lateral positions of the support device are locked to ensure stability after adjustment.

[0013] The fixing device includes two hanging ears arranged at the bottom of the right moving rod, the two hanging ears are arranged parallel to the axial direction of the right moving rod, and an iron chain is arranged between the two hanging ears, and the iron chain is attached to the lower end of the exhaust pipe to support the exhaust pipe. The iron chain is convenient for adapting to exhaust pipes of different sizes, thereby improving the practicality of the supporting device.

[0014] The base comprises a double-layer bottom plate arranged in parallel up and down, and a plurality of damping shock absorbers are arranged between the double-layer bottom plates. The damping shock absorbers perform vibration reduction processing on the exhaust pipeline to attenuate the vibration energy from the exhaust system.

[0015] The base includes a bottom plate in contact with the stand, and a plurality of waist-shaped holes are provided on the bottom plate. The waist-shaped holes can be provided with three arc-shaped holes, and the center of the circle is the center of the bottom plate. The three waist-shaped holes are evenly arranged, and the base and the stand are fixedly connected by T-bolts passing through the waist-shaped holes. The three waist-shaped holes make the base more stably fixed, and the force is evenly distributed, thereby extending the service life of the base.

[0016] In summary, the utility model has the advantages of not being subject to the space requirement of the exhaust system, being highly stable, attenuating vibration, being easy to operate, and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A locking device 6 that can lock the extension length of the telescopic rod is provided on both the vertical telescopic rod 2 and the horizontal telescopic rod 3. For the convenience of description, Figure 1 The left side is left, the right side is right, Figure 1 The upper side is the upper side, and the lower side is the lower side. The left and right adjustment device is provided with a fixing device 4 that can fix the exhaust pipe. The vertical telescopic rod 2 is provided with a fine-tuning device 5 that can adjust the height, and a locking device 6 is also provided in the fine-tuning device 5. The height of the fixing device 4 is adjusted by the vertical telescopic rod 2, and the left and right positions of the fixing device 4 are adjusted by the transverse telescopic rod 3. After the fixing device 4 is adjusted to the approximate position of the exhaust pipe, the height of the vertical telescopic rod 2 and the length of the transverse telescopic rod 3 are locked by the locking device 6, so that the fixing device 4 can fix the exhaust pipe conveniently. The exhaust pipe is fixed by the fixing device 4, and the height of the transverse telescopic rod 3 is adjusted upward by the fine-tuning device 5 of the vertical telescopic rod 2 until the exhaust pipe is completely constrained, and the fine-tuning device 5 is locked by the locking device 6. In this way, the stability of the exhaust pipe is ensured, and the base 1 is fixed on the stand to avoid the skewness of the support device during use, and at the same time to avoid the loosening or falling of the support device. The structure of the vertical telescopic rod 2 and the horizontal telescopic rod 3 reduces the space required for the supporting device and is not limited by the exhaust pipe space. It can be widely used for the installation and fixation of the engine stand exhaust pipe and similar structures.

[0025] like Figure 1 , 2As shown in , 3, 6, and 7, the base 1 includes a bottom plate 11 placed on the stand, and a waist-shaped hole 12 arranged around the bottom plate 11 is provided on the bottom plate 11. The waist-shaped hole 12 is an arc-shaped through hole. The base 1 can be fixed to the stand rail groove by passing a bolt through the waist-shaped hole 12, thereby ensuring the stability of the support device. In this embodiment, there are three waist-shaped holes 12, and the three waist-shaped holes 12 are evenly arranged. Then, the base 1 can be fixed by passing through the three waist-shaped holes 12 respectively through the T-bolt, so that the fixing points can be evenly arranged, thereby ensuring the stability of the base 1. At the same time, the setting of the three waist-shaped holes 12 increases the available positions for bolt fixing, and the bolt fixing position is selected according to the position of the stand rail groove, thereby increasing the applicability of the base 1 to the stand when it is fixed. In this embodiment, the base 1 includes a double-layer bottom plate 11 arranged in parallel up and down, and the lower bottom plate 11 is fitted with the stand. A plurality of damping shock absorbers 7 are arranged between the double-layer bottom plates 11, and the damping shock absorbers 7 perform vibration reduction treatment on the exhaust pipe to attenuate the vibration energy from the exhaust system. In this embodiment, three damping shock absorbers 7 are provided, and the three damping shock absorbers 7 are evenly arranged to evenly attenuate the vibration energy of the exhaust system.

[0026] like Figure 1-3 As shown in Figures 7 and 8, the vertical telescopic rod 2 includes a fixed rod 21 and a movable rod 22. The fixed rod 21 is a vertically arranged tubular shape. The movable rod 22 is inserted in the fixed rod 21 and can move up and down. The upper end of the fixed rod 21 is provided with a locking device 6 that can lock the upper and lower positions of the movable rod 22. A limit observation port is provided on the fixed rod 21, and the internal movable rod 22 can be observed through the limit observation port. A striking mark is applied to the bottom of the outer surface of the movable rod 22. When observing from the limit observation port, when the striking mark is seen, it means that the movable rod 22 is already at the highest point, and the vertical telescopic rod 2 has been extended to the highest point, so as to avoid the movable rod 22 from falling off due to the continued upward movement of the movable rod 22, thereby ensuring stability when the height changes. In this embodiment, the fixed rod 21 and the movable rod 22 are both round tubes, and the movable rod 22 can rotate along the axis in the fixed rod 21, so as to facilitate the movement of the fixing device 4 to the desired position, thereby adapting to the space of different exhaust systems and increasing applicability. A plurality of ribs 8 are fixedly connected to the bottom of the outer edge of the fixing rod 21, and the bottom surface of the ribs 8 fits the base 1. The ribs 8 support the fixing rod 21 to ensure the stability of the vertical telescopic rod 2, avoid the skewness of the connection between the vertical telescopic rod 2 and the base 1, and further ensure the stability of the fixing device. In this embodiment, three ribs 8 are provided, and the three ribs 8 are evenly arranged around the fixing rod 21 to ensure stability.

[0027] like Figure 1-4As shown in 7, a fine-tuning rod 51 is inserted into the movable rod 22. The fine-tuning rod 51 is located at the upper part of the movable rod 22. The bottom end of the fine-tuning rod 51 is provided with a thread. The upper end of the fixed rod 21 is provided with an adjusting nut 52 threadedly connected to the fine-tuning rod 51. A handle 53 is provided on the outside of the adjusting nut 52. The rotation of the handle 53 drives the rotation of the adjusting nut 52. The threaded connection between the nut and the fine-tuning rod 51 converts the rotational motion into an up-and-down linear motion, thereby adjusting the up-and-down position of the fine-tuning rod 51. By fine-tuning the up-and-down position of the fine-tuning rod 51, the up-and-down position of the transverse telescopic rod 3 is changed, thereby changing the up-and-down position of the fixing device 4 for fixing the exhaust pipeline, so that the exhaust pipeline can be completely constrained, thereby ensuring the stability of the fixed exhaust pipeline. The top of the movable rod 22 is also provided with a limit observation port, thereby observing the position of the fine-tuning rod 51, avoiding the fine-tuning rod 51 from falling off, thereby ensuring the stability of the supporting device.

[0028] like Figure 1-3 As shown in Figures 7 and 8, the transverse telescopic rod 3 includes a left fixed rod 31 and a right movable rod 32 inserted in the left fixed rod 31. The right end of the left fixed rod 31 is provided with a locking device 6 that can fix the position of the right movable rod 32 in the left fixed rod 31. The left fixed rod 31 and the right movable rod 32 are both square tubes. The square tube prevents the right movable rod 32 from rotating in the left fixed rod 31, prevents the rotation of the fixing device, and ensures the stability of the fixing device. A fixing device 4 is provided on the right end bottom surface of the right movable rod 32. A limit observation port is provided at the right bottom of the left fixed rod 31 of the transverse telescopic rod 3, and the limit observation port can observe the internal right movable rod 32. A striking mark is applied to the bottom of the outer surface of the right movable rod 32. When observing from the limit observation port, when the striking mark is seen, it means that the right movable rod 32 is already at the highest point, and the transverse telescopic rod 3 has been extended to the farthest point, so as to prevent the right movable rod 32 from falling off due to the continued rightward movement of the right movable rod 32, and ensure the stability during the lateral change. The transverse telescopic rod 3 is located at the upper end of the fine-tuning device 5, and the left fixed rod 31 is fixedly connected to the fine-tuning rod 51. In this embodiment, a second rib 9 is provided between the outer surfaces of the left fixed rod 31 and the fine-tuning rod 51, and the stability between the left fixed rod 31 and the fine-tuning rod 51 is enhanced by the second rib 9.

[0029] like Figure 1 As shown, the fixing device 4 includes two lifting ears 41 fixed to the right moving rod 32, and the two ends of the iron chain 42 are respectively connected to the two lifting ears 41.

The locking device 6 includes a locking tube 61 that can be sleeved outside the movable tube and can reduce its diameter. An axial opening is provided on the side wall of the locking tube 61, and both ends of the opening of the locking tube 61 are provided with clamping pieces 62 extending outward. The two clamping pieces 62 are arranged in parallel. A fastening device that can tighten the two clamping pieces 62 is provided between the two clamping pieces 62. In this embodiment, the fastening device is a bolt and nut, and the distance between the two clamping pieces 62 can be tightened by the bolt and nut, so that the inner diameter of the locking tube 61 becomes smaller, so that the locking tube 61 fits the movable pipeline inside. As the spacing between the clamping pieces 62 becomes smaller, the friction between the locking tube 61 and the movable pipeline inside increases, thereby clamping and locking the movable pipeline in the locking tube 61 to achieve locking. The inner surface shape of the locking tube 61 is consistent with the shape of the pipeline that moves inside, so as to achieve fitting and locking with the pipeline that moves inside the locking tube 61. In this embodiment, the locking tube 61 of the locking device 6 used by the vertical telescopic rod 2 and the fine-tuning device 5 is a round tube, and the locking tube 61 of the locking device 6 used by the horizontal telescopic rod 3 is a square tube. In this embodiment, the side of the locking tube 61 away from the opening is connected to the pipeline to be fixed, and a gap is provided between the lower end of the side close to the opening and the pipeline to be fixed, and the gap is set as a limited observation port. The side of the locking tube 61 with the gap is convenient for deformation to change the inner diameter of the locking tube 61, and the limited observation port is convenient for observing the pipeline inside. The limited observation port and the locking device 6 are produced in one piece, which improves the processing efficiency.
