Description

Technical Field

[0001] The invention relates to the field of cable laying, and in particular to a direct burial construction device for cable installation. Background Art

[0002] Cable laying can be divided into several laying methods, such as direct burial laying, pipe laying, cable trench laying and bridge laying, and each laying method has corresponding laying standards. For direct burial cable laying, when there are stones or other hard debris at the bottom of the trench where the cable is laid, it is necessary to first lay a certain thickness of fine sand or soft soil at the bottom of the trench, and then lay the cable on the top, and then lay a certain thickness of fine sand or soft soil above the cable before backfilling. When it is necessary to lay multiple cables directly in the same trench, a certain distance must be ensured between each cable. In the actual laying construction process, workers often use construction machinery (such as forklifts and excavators) to carry out soft The transportation and laying of soil or fine sand, and the spacing between cables are also controlled by workers. However, after the cable spacing is limited during construction, it is often impossible to lay fine sand and soft soil on top in time. When the exposed cables are long, it is easy to cause uneven force on the cables due to the uneven falling of fine sand and soft soil, which can easily cause the cable spacing to change, thereby failing to meet the cable laying requirements and regulations. In addition, when using construction machinery to control the thickness of the laid soft soil or fine sand, the low sensitivity of the construction machinery and the insufficient operating skills of the operators will also cause inconvenience in thickness control, thereby reducing the laying efficiency and highlighting its shortcomings.

[0036] The battery 10, controller 11, reduction motor 12 and push rod motor 32 are electrically connected. The controller 11 has a built-in radio receiving module and an external radio remote control, so that the radio remote control is used to transmit specific radio signals to the controller 11, and then further realizes the control of the forward and reverse rotation of the reduction motor 12 and the extension and retraction of the piston rod of the push rod motor 32. The battery 10 is responsible for providing power to the controller 11, the reduction motor 12 and the push rod motor 32. The rotating shaft of the reduction motor 12 is coaxially connected with the No. 1 main shaft 14 to achieve synchronous rotation. The No. 1 main sprocket 15 and the No. 1 secondary sprocket 19 are driven by chain meshing. When the push rod motor 32 extends and retracts the push rod, the front unloading barrel 6 can swing up and down with the hinge shaft 26 as the axis. When the front unloading barrel 6 swings up and down, the secondary swing arm 16 can swing back and forth with the No. 1 main shaft 14 as the axis through the main swing arm 261 and the connecting arm 27. When the movable arm 16 swings backward, the bottom end of the limit plate 25 can contact the bottom end of the front part of the frame 1.

[0037] The working principle of the present invention is as follows: when in use, the push rod motor 32 is first controlled by a radio remote controller to extend the push rod to the maximum limit and then stop. At this time, the front unloading barrel 6 swings upward to a certain height and stops, and the No. 1 main gear 18 is meshed with the No. 1 sub-gear 60. First, one end of the cable to be laid is fixed on the outer circumferential wall of the cable drum 40 in a clockwise direction, and then the reduction motor 12 is controlled to reverse and observe from the right angle in a counterclockwise direction. The reduction motor 12 will drive the No. 1 main shaft 14 and the No. 1 main sprocket 15 to rotate counterclockwise, and the No. 1 main sprocket 15 will drive the No. 1 sub-sprocket 19, the No. 1 sub-shaft 17, the No. 1 main gear 18 and the No. 2 main gear 20 to rotate counterclockwise through the chain, and at this time the No. 1 main gear 18 will drive the cable drum 40 to rotate clockwise by meshing with the first sub-gear 60, so that the cable can be gradually wound around the outer wall of the cable drum 40 until the cable is completely wound. At this time, the reduction motor 12 is controlled to stop rotating, and the unwound part of the cable end is inserted into the drag assembly 42 in a counterclockwise direction compared to the cable drum 40, and the part of the cable is inserted between the main drag roller 44 and the slave drag roller 46, so that the slave drag roller 46 can clamp the outer wall of the cable together with the main drag roller 44 under the elastic repulsive force of the first compression spring 47. During the reversal of the reduction motor 12, since the pawl 73 in the third one-way transmission assembly 61 allows the ratchet 69 to rotate clockwise compared to it, at this time the third one-way transmission assembly 61 is rotated clockwise. The transmission cylinder 70 in the No. 1 one-way transmission assembly 61 cannot rotate clockwise synchronously with the internal ratchet 69, and then the push rod motor 32 is controlled to fully retract the push rod and stop the action, then the top of the limit plate 25 contacts the top of the frame 1, and the bracket 29 contacts the rear end of the front discharge barrel 6. At this time, the No. 2 main gear 20 is meshed with the No. 2 auxiliary gear ring 54, and the device is placed in the cable trench, so that the forward direction of the device is from the back to the front, which is the laying direction of the cable. Then, fine sand or soft soil, hereinafter referred to as sand, is placed in the front discharge barrel 6 and the rear discharge barrel 7, and then the reduction motor 12 is controlled to rotate clockwise from the right angle, and the reduction motor 12 will drive the No. 1 main shaft 14 and the No. 1 main sprocket 15 to rotate clockwise. , and the No. 1 main sprocket 15 will drive the No. 1 sub-sprocket 19, the No. 1 countershaft 17, the No. 1 main gear 18 and the No. 2 main gear 20 to rotate clockwise through the chain, and at this time, the No. 2 main gear 20 will drive the transmission cylinder 70, the No. 2 main sprocket 52 and the No. 3 main sprocket 53 where the No. 2 sub-gear ring 54 is located to rotate counterclockwise through the engagement with the No. 2 sub-gear ring 54. At the same time, since the ratchet 69 allowed by the pawl 73 in the No. 1 one-way transmission component 51 is rotated in the counterclockwise direction compared to the ratchet 69, under the engagement of the ratchet 69 with the ratchet teeth, the ratchet 69 of the No. 1 one-way transmission component 51 will rotate counterclockwise synchronously with the transmission cylinder 70, so that the rear unloading roller 34 rotates counterclockwise with the No. 2 main sprocket 52 and the No. 3 main sprocket 53,The second main sprocket 52 will drive the second sub-sprocket 5 and the second support shaft 3 to rotate counterclockwise through the chain, so that the support wheel 4 installed on the second support shaft 3 can rotate counterclockwise, and then the device can move forward. The counterclockwise rotation of the third main sprocket 53 will drive the third sub-sprocket 59 and the transmission cylinder 70 in the second one-way transmission assembly 58 to rotate counterclockwise through the chain. Since the pawl 73 in the second one-way transmission assembly 58 allows the ratchet 69 to rotate counterclockwise compared to it, under the engagement of the pawl 73 with the ratchet 69, the fourth support shaft 55, the fourth main sprocket 56 and the third main gear 57 will follow the transmission cylinder 70 and the ratchet 69 in the second one-way transmission assembly 58 to rotate counterclockwise synchronously. , and the third main gear 57 will drive each main drag roller 44 to rotate clockwise through the third sub-gear 50 and the transmission shaft 49, and then use the compression contact of the slave drag roller 46 on the cable, so that the cable wound on the cable reel 40 can be gradually dragged and released, and the fourth main sprocket 56 will drive the fourth sub-sprocket 62, the transmission cylinder 70 and the fourth main gear ring 63 in the third one-way transmission assembly 61 to rotate counterclockwise through the chain, and because the pawl 73 in the third one-way transmission assembly 61 allows the ratchet 69 to rotate clockwise compared to the ratchet 69, the ratchet 69 in the third one-way transmission assembly 61 cannot rotate counterclockwise synchronously with the transmission cylinder 70 at this time, and the fourth main gear ring 63 rotates counterclockwise through the fourth sub-gear 66 and the fifth support shaft 64, the fifth main gear 65 and the fifth sub-gear 67 drive the front unloading roller 33 to rotate counterclockwise, that is, the positive rotation of the reduction motor 12 at this stage can make the second support shaft 3, the rear unloading roller 34 and the front unloading roller 33 rotate counterclockwise, and can drive the transmission shaft 49 to rotate clockwise at the same time, and the counterclockwise rotation of the rear unloading roller 34 and the front unloading roller 33 can make the sand and soil falling in the unloading trough 35 under the action of gravity follow the rotation of the front unloading roller 33 and the rear unloading roller 34 and fall into the ditch continuously, and with the scattering of sand and soil, the second support shaft 3 and the support wheel 4 that continuously rotate counterclockwise of the device and the clockwise rotating transmission shaft 49 and the main drag roller 44 can realize the functions of laying out the line and moving forward at the same time, that is, moving and laying the bottom The bottom of the sand is laid, and the cable is laid above the bottom sand, and the upper sand is laid above the cable. In this process, the movement of the device will cause the movement of the two adjusting cylinders 36 and the two adjusting plates 38, so that the thickness and flatness of the sand can be controlled. Specifically, during operation, the bottom end of the adjusting cylinder 36 at the bottom of the front unloading cylinder 6 should be close to the bottom of the ditch, so that the bottom end of the adjusting cylinder 36 is lower than the bottom end of the adjusting plate 38 slidably connected to the rear of it, and there is a height difference between its bottom end and the bottom end of the adjusting plate 38 slidably connected to the rear of it, which is named H1, and the bottom end of the adjusting cylinder 36 at the bottom of the rear unloading cylinder 7 is close to the highest point of the outer circumferential wall of the laid cable, so that the bottom end of the adjusting cylinder 36 is higher than the bottom end of the adjusting plate 38 in front of it.The height difference between its bottom end and the bottom end of the adjusting plate 38 in front of it is named H2, and at the same time, the bottom end of the adjusting cylinder 36 is lower than the bottom end of the adjusting plate 38 slidably connected to its rear part, and the height difference between its bottom end and the bottom end of the adjusting plate 38 slidably connected to its rear part is named H3, then the size of H1 is the thickness of the bottom sand layer to be controlled, and the sum of the values ​​of H2 and H3 is the thickness of the sand layer above the bottom sand layer to be controlled, and the numerical control of H1 can be manually controlled by adjusting the position of the adjusting plate 38 on the adjusting cylinder 36 below the front unloading cylinder 6, and the numerical control of H2 can be manually controlled by adjusting the height of the adjusting cylinder 36 at the bottom of the rear unloading cylinder 7 compared to the adjusting plate 38 in front of it. The numerical control of H3 can be manually controlled by adjusting the position of the adjusting plate 38 on the adjusting cylinder 36 at the bottom of the rear unloading cylinder 7. Specifically, the No. 1 tightening bolt 37 is manually rotated to tighten it at different positions of the front unloading cylinder 6 and the rear unloading cylinder 7, so that the adjusting cylinder 36 can be restricted to different positions of the front unloading cylinder 6 and the rear unloading cylinder 7. The No. 2 tightening screw is manually rotated to tighten it at different positions of the adjusting cylinder 36, so that the adjusting plate 38 can be restricted to different positions of the adjusting cylinder 36. Before laying out the line, the No. 3 tightening bolt 48 is manually rotated to tighten it at different positions of the No. 1 support arm 41, so that the sliding seat can be restricted to different positions of the No. 1 support arm 41, thereby indirectly limiting the horizontal distance between the main drag rollers 44. The cable spacing can be controlled during the laying of the cables, so that the cable spacing during the laying of the cables can be controlled. When the device needs to be moved backward during laying in the trench, the reduction motor 12 is controlled to be reversed. It can be seen from the above transmission process that the second auxiliary gear ring 54, the second main sprocket 52 and the third main sprocket 53 will rotate clockwise by utilizing the meshing of the second main gear 20 with the second auxiliary gear ring 54, and the clockwise rotating second main sprocket 52 will drive the second auxiliary sprocket 5 and the second support shaft 3 to rotate clockwise through the chain, thereby utilizing the support wheel 4 that rotates with the second support shaft 3 to realize the backward movement of the device. Since the ratchet 73 inside the first one-way transmission component 51 allows the ratchet 69 to rotate counterclockwise compared to the first one-way transmission component 51, the first one-way transmission component 51 is rotated counterclockwise. 1 cannot rotate synchronously with the transmission cylinder 70, so the rear unloading cylinder 7 does not rotate at this time, and the clockwise rotation of the No. 3 main sprocket 53 drives the No. 3 secondary sprocket 59 and the transmission cylinder 70 in the No. 2 one-way transmission assembly 58 to rotate clockwise through the chain. Since the pawl 73 in the No. 2 one-way transmission assembly 58 allows the ratchet 69 to rotate counterclockwise compared to the reverse direction of its rotation, the ratchet 69 in the No. 2 one-way transmission assembly 58 cannot rotate synchronously with the transmission cylinder 70, so the No. 4 support shaft 55 does not rotate at this time, then the cable drum 40, the transmission shaft 49 and the front unloading roller 33 do not rotate together with the No. 4 support shaft 55, so the device in this state can move backward conveniently without continuing to release the line and lower the sand.

[0038] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
