Description

Technical Field

[0001] The invention relates to the technical field of laser cleaning, and in particular to a track assembly tensioning and adjusting mechanism. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] After the gun barrel is used, residues will adhere to its inner wall, which will reduce the smoothness of the inner wall and increase friction resistance. Therefore, corresponding equipment is needed to clean the inner wall. Laser cleaning can effectively remove impurities from the inner wall of the gun barrel.

[0004] The current laser cleaning equipment travels in the gun barrel via a track traveling mechanism. By adjusting the track tension, the contact tightness between the track and the drive wheel and guide wheel can be improved, and the adhesion of the track to the gun barrel can be improved. The existing track tensioning adjustment mechanism is independently arranged on each track traveling mechanism. However, in order to ensure that the cleaning equipment is in the middle of the gun barrel during laser cleaning, there are often multiple track traveling mechanisms, which are arranged in a ring shape on the laser cleaning equipment. As a result, when debugging the laser cleaning equipment, it is necessary to operate multiple track tensioning adjustment mechanisms in sequence for adjustment, which is not only time-consuming and labor-intensive, but also has the problem of unilateral wear of the track due to inconsistent tension adjustment. Summary of the invention

[0005] The purpose of the present invention is to provide a track assembly tension adjustment mechanism to address the above-mentioned deficiencies, so as to achieve the purpose of being able to adjust the tension of multiple tracks at the same time.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-5 The present invention discloses a track assembly tensioning and adjusting mechanism, which is used for tensioning and adjusting multiple track assemblies of a laser cleaning device, and comprises:

[0033] A plurality of sliding assemblies 1, used to be connected to the tensioning pulley 51 of each track assembly 5, and capable of driving the tensioning pulley 51 to move toward and away from the driving pulley 52 of the track assembly 5;

[0034] The adjustment component 2 is arranged on the central tube 6 of the laser cleaning device and can move along the axial direction of the central tube 6;

[0035] A plurality of push-up connecting rods 3 are provided, one end of each push-up connecting rod 3 is rotatably connected to the adjusting assembly 2, and the other end is rotatably connected to the corresponding sliding assembly 1, and is used for pushing the corresponding sliding assembly 1 to move in the same direction when the adjusting assembly 2 moves.

[0036] The present invention enables the adjustment component 2 to move along the axis of the central tube 6, while driving the plurality of push links 3 to move together, so that the plurality of sliding components 1 connected to the push links 3 change positions at the same time, thereby completing the adjustment of the track tension in the plurality of track assemblies. Since the movement distances of the plurality of sliding components 1 are consistent, it can achieve the effect of saving time and labor, and can ensure that the tension of each track assembly is adjusted consistently.

[0037] In one embodiment, the sliding assembly 1 comprises:

[0038] The inner sliding member 11 is slidably disposed between the two outer contour plates 53 of the crawler assembly 5 and is rotationally connected to the tension pulley 51;

[0039] The outer sliding component 12 is slidably disposed on the crawler track assembly 5 . The outer sliding component 12 is detachably connected to the inner sliding component 11 , and the outer sliding component 12 is rotatably connected to the corresponding push link 3 .

[0040] Such a design enables the push link 3 to be connected with the outer sliding component 12, so that the inner sliding component 11 moves along with the push link 3. Meanwhile, by disassembling and separating the inner sliding component 11 from the outer sliding component 12, the convenience of crawler track installation can be improved.

[0041] In one embodiment, the inner sliding component 11 includes a tensioning slider 111 which is slidably disposed between the two outer contour plates 53 and is rotatably connected to the tensioning pulley 51. A connecting block 112 is disposed on the side of the tensioning slider 111 away from the tensioning pulley 51. The connecting block 112 is detachably connected to the outer sliding component 12 by screws. A wedge-shaped slider 113 which abuts against the tensioning slider 111 is slidably connected in the connecting block 112. The contacting sides of the wedge-shaped slider 113 and the tensioning slider 111 are both inclined surfaces. An adjusting screw 114 is threadedly connected to the connecting block 112 and is used to push the wedge-shaped slider 113 to squeeze the tensioning slider 111 and make the tensioning slider 111 move to the side away from the connecting block 112.

[0042] The outer contour plate 53 is provided with a strip-shaped hole for the screw and the adjusting screw 114 to slide.

[0043] This design allows the operator to screw in the adjusting screw 114 when it is necessary to individually adjust the track tension of the corresponding track assembly 5, so that the tensioning slider 111 is pushed by the inclined surface of the wedge-shaped slider 113 and moves to the side away from the connecting block 112, so that the distance between the tensioning pulley 51 and the driving pulley 52 changes, so that the tensioning adjustment mechanism can not only adjust the tension of multiple tracks at the same time, but also adjust the required track individually as needed.

[0044] In one embodiment, the adjustment component 2 comprises:

[0045] The collar 21 is slidably disposed on the central tube 6 and is located inside the protective shell 7 of the laser cleaning device, and is used to connect with each push rod 3;

[0046] The driving component 22 is slidably disposed on the central tube 6 and is located outside the protective shell 7 of the laser cleaning device, and is used to push the collar 21 to move along the axial direction of the central tube 6;

[0047] A plurality of pull rods 23 are disposed between the collar 21 and the driving component 22 to enable the driving component 22 and the collar 21 to move synchronously.

[0048] This design enables the operator to adjust the position of the collar 21 by operating the driving component 22 in the outer area of ​​the protective shell 7 , which is more convenient than directly adjusting the position of the collar 21 in the protective shell 7 .

[0049] In one embodiment, the driving component 22 includes an adjusting ring 221 which is sleeved on the central tube 6 and threadedly connected to the central tube 6. A movable slip ring 222 which can move synchronously with the adjusting ring 221 is rotatably arranged on one side of the adjusting ring 221 close to the sleeve ring 21. The pull rod 23 is arranged between the movable slip ring 222 and the sleeve ring 21.

[0050] With this design, the adjusting ring 221 is rotated and screwed into the central tube 6 to drive the movable slip ring 222 to move, and then the pull rod 23 pulls the sleeve ring 21 to move. Since the adjusting ring 221 and the movable slip ring 222 are rotatably arranged, the movable slip ring 222 does not need to rotate synchronously with the adjusting ring 221, thereby avoiding the problem of collision between the pull rod 23 and other components in the laser cleaning equipment when the adjusting ring 221 is rotated.

[0051] In one embodiment, the adjustment assembly 2 further includes a positioning ring 24 fixedly disposed on the central tube 6 and detachably connected to the protective shell 7. The positioning ring 24 is located between the sleeve ring 21 and the driving component 22, and a through hole is opened on the positioning ring 24 for the pull rod 23 to pass through.

[0052] This design enables the two sides of the protective shell 7 to be connected and fixed to the air curtain assembly 4 and the positioning ring 24 respectively, thereby improving the installation stability of the protective shell 7. At the same time, by passing the pull rod 23 through the through hole, the rotation of the pull rod 23 can be further restricted so that the pull rod 23 can only move along the set direction.

[0053] In one embodiment, the shape surrounded by the push rod 3, the central tube 6, the fixed rod 8 of the laser cleaning device and the crawler assembly 5 is a parallelogram.

[0054] Such a design enables the push link 3 to rotate synchronously when the fixed link 8 is rotated to adjust the distance between the track assembly 5 and the center tube 6, so that the relative position of the adjusted track assembly 5 and the sliding assembly 1 can remain unchanged, thereby making the use of the tensioning adjustment mechanism not limited by the position change of the track assembly 5 and having a wider range of uses.

[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] In addition, "plurality" means two or more.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
