Description

Technical Field

[0001] The present application relates to the field of crawler track technology, and in particular to a crawler track steering control structure. Background Art

[0002] The crawler track is a flexible chain link driven by the driving wheel, surrounding the driving wheel, road wheel, idler wheel and track roller. It is composed of track shoes and track pins. The main function of the crawler track is to increase the contact area between the mechanical vehicle and the ground, thereby reducing the pressure, which is especially important on soft or uneven ground. In addition, the application of crawler tracks is not limited to land vehicles. Some crawler tracks are also used on some deep-sea or space operation equipment.

[0003] The steering angle of the submarine trenching device itself is not very large, and the movement of the device itself will be subject to certain restrictions during operation, and relatively stable and precise steering cannot be guaranteed. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a track steering control structure, which has the advantages of realizing fine-tuning of the track deflection angle and ensuring the stability of the angle after steering, while also improving the stability of the device during movement. It solves the problem that the steering angle of the submarine trenching device itself is not very large, and the movement of the device itself will be subject to certain restrictions during operation, and relatively stable and precise steering cannot be guaranteed.

[0005] The top of the lifting column is rotatably connected to the lifting column by the support frame, and the upper end of the lifting column is rotatably connected to the lifting column by the support frame.

[0006] Through the above scheme, since the steering angle of the submarine trenching device itself is not very large, the movement of the device itself will be subject to certain restrictions during operation, and relatively stable and precise steering cannot be guaranteed. The rack is driven to move by the cylinder, which prompts the gear to drive the gear ring to rotate, and then drives the support frame to rotate relative to the connecting plate, and the crawler is independently adjusted in angle to facilitate the steering movement of the trenching device. By arranging a damper, a first spring and a second spring, the trenching device connected to the connecting plate is buffered and shock-absorbing, thereby improving the stability of the device during movement.

[0007] Furthermore, the outer circumferential surface of the lifting column is fixedly connected with first limit blocks arranged at equal intervals, and the outer surfaces of the first limit blocks are slidably connected to the base through empty grooves opened inside the base.

[0008] Through the above solution, the lifting column is restricted to prevent the lifting column from rotating inside the base, so that the lifting column is always lifted and lowered longitudinally, thereby improving the stability of the lifting column movement.

[0009] Furthermore, a slider is fixedly connected to the bottom surface of the rack, a first slide rail is fixedly connected to the inner bottom wall of the support frame, and an outer surface of the slider is slidably connected to the first slide rail.

[0010] Through the above solution, the rack is restricted, so that the rack always follows the slider and moves with the first slide rail as the track, thereby improving the stability of the rack movement.

[0011] Furthermore, the outer surface of the connecting plate is fixedly connected to a fixed plate, the interior of the fixed plate is fixedly plugged with an insertion rod, the inner bottom wall of the support frame is fixedly connected to a second slide rail, the interior of the second slide rail is slidably connected to a socket, and the outer circumferential surface of the insertion rod is slidably plugged with the interior of the socket.

[0012] Through the above solution, the second slide rail, the socket, the insertion rod and the fixing plate can limit the rotation angle of the support frame, avoid the crawler track from rotating at an excessive angle, and improve the stability of the crawler track movement.

[0013] Furthermore, a collar is fixedly sleeved on the outer circumferential surface of the socket, and the outer surface of the collar is slidably connected to the second slide rail through a slot provided inside the second slide rail.

[0014] Through the above solution, the socket is restricted to prevent the socket from easily falling off from the inside of the second slide rail, thereby improving the stability of the socket movement.

[0015] Furthermore, a second spring is fixedly connected to the upper surface of the socket, and a top end of the second spring is fixedly connected to the bottom surface of the fixing plate.

[0016] Through the above solution, the second spring cooperates with the damper and the first spring to provide a shock-absorbing effect for the trenching device, thereby improving the stability of the trenching device during the steering movement.

[0017] Furthermore, the outer circumferential surface of the insertion rod is fixedly connected with second limiting blocks arranged at equal intervals, and the outer surfaces of the second limiting blocks are slidably connected to the socket through empty grooves opened inside the socket.

[0018] Through the above solution, the insertion rod is restricted, so that the insertion rod is always lifted and lowered longitudinally, while also preventing the insertion rod from easily falling off from the inside of the socket.

[0019] Furthermore, the width of the gear is greater than the width of the gear ring, and the size of the gear ring is greater than the size of the gear.

[0020] Through the above solution, the gear with a width greater than the gear ring can prompt the gear ring to rise and fall a certain distance following the connecting plate, and the gear with a size smaller than the gear ring can achieve the effect of reduction transmission, thereby improving the stability of the track during steering.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The crawler steering control structure drives the rack to move through the oil cylinder, prompting the gear to drive the gear ring to rotate, and then drives the support frame to rotate relative to the connecting plate, independently adjusting the angle of the crawler to facilitate the steering movement of the trenching device. By arranging a damper, a first spring and a second spring, the trenching device connected to the connecting plate is buffered and shock-absorbing, thereby improving the stability of the device during movement and solving the problem that the steering angle of the existing submarine trenching device is not large and cannot ensure relatively stable and accurate steering.

[0033] See also Figure 2 and Figure 3 The bottom surface of the rack 7 is fixedly connected with a slider 12, and the inner bottom wall of the support frame 1 is fixedly connected with a first slide rail 13. The outer surface of the slider 12 is slidably connected to the first slide rail 13 to restrict the rack 7, so that the rack 7 always follows the slider 12 and moves with the first slide rail 13 as the track, thereby improving the stability of the rack 7 movement.

[0034] See also Figure 2 、 Figure 3 and Figure 5The outer surface of the connecting plate 4 is fixedly connected to the fixing plate 14, and the inside of the fixing plate 14 is fixedly plugged with an insertion rod 15.

[0035] See also Figure 3 and Figure 5 The outer circumference of the socket 16 is fixedly sleeved with a ring 18, and the outer surface of the ring 18 is slidably connected to the second slide rail 17 through the empty groove opened inside the second slide rail 17, thereby restricting the socket 16, preventing the socket 16 from easily falling off from the inside of the second slide rail 17, and improving the stability of the socket 16 movement.

[0038] See also Figure 2 and Figure 3 The width of the gear 8 is greater than the width of the gear ring 5, and the size of the gear ring 5 is greater than the size of the gear 8.

By providing a damper 9, a first spring 10 and a second spring 19, the trenching device connected to the connecting plate 4 is buffered and shock-absorbing, thereby improving the stability of the device during movement and solving the problem that the steering angle of the existing submarine trenching device is not large and cannot ensure relatively stable and accurate steering.

[0040] It should be noted that the slider 12 is a T-shaped structure.

[0041] The working principle of the above embodiment is:

[0042] The connecting plate 4 is fixedly connected to the four corner positions of the external trenching device. When the device needs to be turned, the oil cylinder 6 is started as the power to drive the rack 7 to move through the output end, and the rack 7 drives the gear 8 to rotate. When the gear 8 rotates, it will engage with the gear ring 5, and then drive the support frame 1 to rotate relative to the connecting plate 4. Then the support frame 1 drives the track 21 to rotate through the external roller, and the angle of the track 21 is adjusted. When the trenching equipment is subjected to bumps and impacts during movement, the damper 9, the first spring 10 and the second spring 19 are all squeezed, and the damper 9, the first spring 10 and the second spring 19 will generate a reaction force to cushion the impact on the device and improve the stability of the device during movement.
