Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a fixing device for a periscope transmission rod. Background Art

[0002] There are often various faults in municipal sewer pipes. When a sewer pipe fails somewhere, it is necessary to open the inspection well for dredging and maintenance. During the maintenance, it is necessary to use pipeline periscope detection technology for detection.

[0003] When using a periscope for pipeline inspection, it usually requires two workers to work together, one of whom is responsible for fixing and retracting the periscope transmission rod, and the other is responsible for the camera lens shooting operation. However, when the workers manually support and fix the periscope transmission rod, the periscope will inevitably shake due to human factors, resulting in unclear image data, which will affect the identification and judgment of pipeline defects to a certain extent. In addition, when conducting pipeline inspections on large well chambers or eccentric wells, in addition to manually fixing and retracting the periscope transmission rod, it is also necessary to manually manipulate the rotation of the periscope transmission rod. However, when manually adjusting the rotation of the periscope transmission rod, it is not only difficult to control the rotation angle, but also difficult to ensure the stability of the camera lens during the rotation, so it is not easy to get a clear picture. Summary of the invention

[0004] Based on this, it is necessary to provide a fixing device for a periscope transmission rod to address the above-mentioned problems. When the fixing device for the periscope transmission rod is used in pipeline inspection, not only can a single person complete the pipeline inspection work, but also the shaking problem of the periscope transmission rod caused by manual support and fixation can be avoided, as well as the problem of instability of the periscope when the periscope transmission rod is rotated manually, thereby effectively improving the accuracy and integrity of the pipeline inspection picture and reducing the work intensity.

[0005] The technical solution is as follows:

[0006] On the one hand, a fixing device for a periscope transmission rod is provided, comprising:

[0007] A support rod, the support rod is used to be erected at the entrance of the inspection well;

[0008] A fixing member, the fixing member is arranged at one side of the support rod, the fixing member is used to be movably connected with the periscope transmission rod, the fixing member has a locked state in which it can be relatively fixed with the periscope transmission rod and a loose state in which it can slide relatively with the periscope transmission rod; the fixing member is provided with a first gear;

[0009] A driving member, the driving member includes a driving part and a connecting rod connected to each other, the driving part is arranged on the side of the support rod away from the fixed member, one end of the connecting rod away from the driving part passes through the support rod and extends to the side where the fixed member is located, the connecting rod is rotatably connected to the support rod, and a second gear is sleeved on the outer periphery of the connecting rod, and the second gear is meshed with the first gear.

[0010] In the above-mentioned fixing device of the periscope transmission rod, since the fixing part has a locking state that can be relatively fixed with the periscope transmission rod and a loose state that can slide relatively with the periscope transmission rod, and the support rod can be erected at the entrance of the inspection well, when the fixing part is relatively fixed with the periscope transmission rod, the setting of the support rod 1 can not only keep the length of the periscope transmission rod extending into the inspection well unchanged, but also effectively avoid the periscope shaking caused by human factors, so that the camera lens in the periscope can capture clear video data, which is conducive to the staff to identify and judge pipeline defects based on the video data. When the periscope transmission rod slides relative to the fixing part, the extension length of the periscope transmission rod can be effectively adjusted to detect different positions of the pipeline. Since the second gear provided on the connecting rod is meshed with the first gear provided on the fixing member, and the connecting rod is rotatably connected to the support rod, when the external force drives the driving part to rotate, the driving part can drive the connecting rod to drive the second gear to rotate, so that the second gear can drive the first gear to drive the fixing member to rotate relative to the support rod, thereby realizing the swing of the periscope transmission rod, so as to realize the angle adjustment of the periscope transmission rod. Among them, since the angle adjustment of the periscope transmission rod is realized by the gear meshing method, the rotation angle of the periscope transmission rod can be accurately adjusted by controlling the rotation angle of the driving part. At the same time, since the gear meshing movement is relatively stable, the periscope can maintain a relatively stable state during the rotation process, which is conducive to improving the accuracy and integrity of the pipeline detection picture, and is conducive to reducing the work intensity. In addition, since the fixing device of the periscope transmission rod can not only adjust the extension length of the periscope transmission rod, but also adjust the verticality of the periscope transmission rod, when the pipe mouth is offset, tilted or tilted upward, the fixing device of the periscope transmission rod can adjust the position of the periscope through multiple degrees of freedom to ensure that the periscope can feedback clear video data to ensure the accuracy of the detection.

[0012] In one embodiment, the first gear includes an inner gear, the second gear includes an outer gear, and the second gear is located between the fixing member and the support rod.

[0035] Referring to FIG. 1 , FIG. 2 and FIG. 3 , a fixing device 100 for a periscope transmission rod provided in one embodiment of the present application includes a support rod 1, a fixing member 4 and a driving member 6, wherein:

[0036] The support rod 1 is used to be erected at the entrance of the inspection well. The fixing member 4 is arranged on one side of the support rod 1, and the fixing member 4 is used to be movably connected with the periscope transmission rod 200. The fixing member 4 has a locked state that can be relatively fixed with the periscope transmission rod 200 and a relaxed state that can slide relatively with the periscope transmission rod 200. The fixing member 4 is provided with a first gear 7. The driving member 6 includes a driving part 61 and a connecting rod 62 that are connected. The driving part 61 is arranged on the side of the support rod 1 away from the fixing member 4. The end of the connecting rod 62 that is away from the driving part 61 passes through the support rod 1 and extends to the side where the fixing member 4 is located. The connecting rod 62 is rotatably connected to the support rod 1. The outer periphery of the connecting rod 62 is provided with a second gear 8, and the second gear 8 is meshed with the first gear 7.

[0037] In the above-mentioned periscope transmission rod fixing device 100, since the fixing member 4 has a locking state that can be relatively fixed with the periscope transmission rod 200 and a loose state that can slide relatively with the periscope transmission rod 200, and the support rod 1 can be erected at the entrance of the inspection well, when the fixing member 4 is relatively fixed with the periscope transmission rod 200, the setting of the support rod 1 can not only keep the length of the periscope transmission rod 200 extending into the inspection well unchanged, but also effectively avoid the shaking of the periscope 201 caused by human factors, so that the camera lens in the periscope 201 can capture clear video data, which is conducive to the staff to identify and judge pipeline defects based on the video data. When the periscope transmission rod 200 slides relative to the fixing member 4, the extension length of the periscope transmission rod 200 can be effectively adjusted to detect different positions of the pipeline. Since the second gear 8 provided on the connecting rod 62 is meshed with the first gear 7 provided on the fixing member 4, and the connecting rod 62 is rotatably connected with the support rod 1, when the external force drives the driving part 61 to rotate, the driving part 61 can drive the connecting rod 62 to drive the second gear 8 to rotate, so that the second gear 8 can drive the first gear 7 to drive the fixing member 4 to rotate relative to the support rod 1, thereby realizing the swing of the periscope transmission rod 200, so as to realize the angle adjustment of the periscope transmission rod 200. Among them, since the angle adjustment of the periscope transmission rod 200 is realized by the gear meshing method, the rotation angle of the periscope transmission rod 200 can be accurately adjusted by controlling the rotation angle of the driving part 61. At the same time, since the gear meshing movement is relatively stable, the periscope 201 can maintain a relatively stable state during the rotation process, which is conducive to improving the accuracy and integrity of the pipeline detection picture, and is conducive to reducing the operation intensity. In addition, since the fixing device 100 of the periscope transmission rod can not only adjust the extension length of the periscope transmission rod 200, but also adjust the verticality of the periscope transmission rod 200, when the pipe mouth is offset, tilted or tilted upward, the fixing device 100 of the periscope transmission rod can adjust the position of the periscope 201 through multiple degrees of freedom to ensure that the periscope 201 can feedback clear video data to ensure the accuracy of the detection.

[0038] Optionally, the support rod 1 is rotatably connected to the fixing member 4, so that when the driving member 6 is not obtained, the support rod can support the fixing member 4, and when the driving member 6 is driven, the fixing member 4 can rotate relative to the support rod 4 under the drive of the second gear 8 to achieve angle adjustment of the periscope transmission rod 200.

[0039] In one embodiment, as shown in Fig. 3, the first gear 7 includes an internal gear, the second gear 8 includes an external gear, and the second gear 8 is located between the fixing member 4 and the support rod 1. In this way, the first gear 7 is internally meshed with the second gear 8, which enables the second gear 8 to not only drive the fixing member 4 to drive the periscope transmission rod 200 to rotate relative to the support rod 1 through the first gear 7, but also play a role in connecting and supporting the fixing member 4, which is conducive to simplifying the structure.

[0040] Optionally, one end of the connecting rod 62 away from the driving portion 61 is rotatably connected to the fixing member 4. In this way, the connecting rod 62 can support the fixing member 4.

[0041] In other embodiments, both the first gear 7 and the second gear 8 may be external gears, and the first gear 7 is externally meshed with the second gear 8. In order to allow the fixing member 4 to be supported by the support rod 1 and to rotate relative to the support rod 1, the support rod 1 and the fixing member 4 may be connected via a support member, wherein the support member is rotationally connected to the fixing member 4 and fixedly connected to the support rod 1. In order for the second gear 8 to drive the first gear 7 and the fixing member 4 to rotate synchronously, the connecting line between the rotation center of the fixing member 4 when rotating relative to the support member and the rotation center of the first gear 7 should be parallel to the extension direction of the connecting rod 62.

[0042] In one embodiment, as shown in FIG3 , a protruding structure 611 is convexly disposed on the outer peripheral surface of the driving part 61. This facilitates the staff to hold the driving part 61, so as to drive the connecting rod 62 to rotate through the driving part 61, thereby adjusting the angle of the periscope transmission rod 200.

[0043] In one embodiment, as shown in FIG. 1 and FIG. 2 , the fixing member 4 includes a fixing portion 43, a hoop 42a and a locking member 41. The fixing portion 43 is connected to the hoop 42a. The hoop 42a is used to be sleeved on the outer periphery of the periscope transmission rod 200. In the locked state, the hoop 42a can be relatively fixed to the periscope transmission rod 200. In the relaxed state, the hoop 42a can slide relative to the periscope transmission rod 200. The locking member 41 is connected to the hoop 42a. The locking member 41 is used to drive the fixing member 4 to switch between the locked state and the relaxed state. The first gear 7 is provided on the fixing portion 43. In this way, when the fixing member 4 is in the relaxed state, the periscope transmission rod 200 can slide relative to the hoop 42a to adjust the length of the periscope 201 extending into the inspection well. When the fixing member 4 is in a locked state where the hoop 42a and the periscope transmission rod 200 are relatively fixed, the staff can drive the connecting rod 62 to rotate through the driving part 61, so that the second gear 8 can drive the first gear 7 to rotate to adjust the angle of the periscope transmission rod 200, thereby adjusting the angle of the periscope transmission rod 200. Among them, since the hoop 42a can relatively fix the periscope transmission rod 200 during the detection process, the problem of shaking of the transmission rod caused by manual support and fixation can be effectively avoided, so as to ensure that the image data captured by the periscope 201 is clear and reliable, which is conducive to the staff to identify and judge the pipeline defects. In addition, since the rotation of the periscope transmission rod 200 is realized by gear meshing, it is not only possible to effectively control the rotation angle of the periscope transmission rod 200, but also possible to ensure that the periscope 201 can maintain a relatively stable state during the rotation process, thereby facilitating the improvement of the accuracy and integrity of the pipeline detection picture.

[0044] Further, in one embodiment, as shown in FIG. 3 , the hoop 42a includes two hoop plates 42 arranged opposite to each other, each hoop plate 42 includes an arc plate 421 and a wing plate 422 connected to each other, one end of each arc plate 421 away from the wing plate 422 is rotatably connected to the fixing portion 43, and the two arc plates 421 together form a hoop hole 4a for the periscope transmission rod 200 to pass through, and the locking member 41 is connected to both wing plates 422. In this way, when the locking member 41 relaxes the two wing plates 422, the fixing member 4 is in a relaxed state, so that the periscope transmission rod 200 can slide relative to the hoop 42a to adjust the length of the periscope 201 extending into the inspection well. When the locking member 41 locks the two wing plates 422, the hoop 42a is relatively fixed to the periscope transmission rod 200, and the fixing member 4 is in a locked state. At this time, the staff can drive the connecting rod 62 to rotate through the driving part 61, so that the second gear 8 can drive the first gear 7 to rotate to adjust the angle of the periscope transmission rod 200, thereby adjusting the angle of the periscope transmission rod 200.

[0045] Further, in one embodiment, as shown in combination with FIG. 2 and FIG. 3 , a first anti-slip member 5 is provided on the surface of any curved plate 421 facing the other curved plate 421. In this way, when the clamp 42a is connected to the periscope transmission rod 200, the first anti-slip member 5 can effectively increase the friction between the periscope transmission rod 200, thereby preventing the periscope transmission rod 200 from moving relative to the clamp 42a during the detection process, thereby facilitating the stability of the periscope 201 during the pipeline detection process and improving the accuracy and integrity of the pipeline detection picture.

[0046] Optionally, the first anti-slip member 5 may be a rubber member.

[0047] In one embodiment, as shown in combination with FIG. 1 and FIG. 2 , an auxiliary rod 2 is provided at the end of the support rod 1, and the extension direction of the auxiliary rod 2 is arranged at an angle with the extension direction of the support rod 1, and the end of the auxiliary rod 2 that is away from the support rod 1 extends toward the side where the fixing member 4 is located or toward the side where the driving part 61 is located. In this way, the contact area between the fixing device 100 of the periscope transmission rod and the edge of the wellhead can be increased, which is conducive to ensuring that the fixing device 100 of the periscope transmission rod can reliably support and fix the periscope transmission rod 200.

[0048] Optionally, the extension direction of the auxiliary rod 2 is perpendicular to the extension direction of the support rod 1. This is beneficial to improve the reliability and stability of the connection between the auxiliary rod 2 and the support rod 1.

[0049] Optionally, the auxiliary rod 2 and the support rod 1 may be connected via a connecting piece, wherein the connecting piece includes but is not limited to a screw, a pin, a clamping structure, etc. Alternatively, the auxiliary rod 2 and the support rod 1 may be integrally formed.

[0050] Optionally, there are two auxiliary rods 2, and the two auxiliary rods 2 are respectively connected to the two ends of the support rod 1. In this way, the contact area between the fixing device 100 of the periscope transmission rod and the edge of the wellhead can be further increased, thereby facilitating the fixing device 100 of the periscope transmission rod to reliably support and fix the periscope transmission rod 200.

[0051] In one embodiment, as shown in FIG1 , the auxiliary rod 2 has a bottom surface for contacting with the wellhead edge of the inspection well, and the bottom surface is provided with a second anti-slip member 3. In this way, the friction between the auxiliary rod 2 and the wellhead edge can be effectively increased, thereby preventing the support rod 1 and the auxiliary rod 2 from moving relative to the wellhead edge, so as to ensure the stability of the periscope 201 during pipeline inspection, thereby facilitating improving the accuracy and integrity of the pipeline inspection picture.

[0052] Optionally, as shown in FIG1 , the second anti-slip member 3 is a columnar structure, and the outer diameter of the second anti-slip member 3 gradually decreases from the end close to the auxiliary rod 2 to the end away from the auxiliary rod 2. In this way, during the pipeline inspection process, when the pressure on the auxiliary rod 2 and the support rod 1 increases, the contact area between the second anti-slip member 3 and the wellhead edge can be increased, thereby ensuring that the second anti-slip member 3 can effectively achieve a protective effect.

[0053] Optionally, the second anti-slip member 3 is a rubber member, so that the second anti-slip member 3 also plays a buffering role.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
