Description

Technical Field

[0001] This invention relates to the field of buried wire technology in hydropower construction, and in particular to an automatic buried wire device and method for hydropower construction. Background Technology

[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. As society develops, water conservancy and hydropower projects will be continuously maintained and expanded. During the construction of water conservancy and hydropower projects, cable burial operations are often carried out. By burying cables underground, not only can the cables be well protected, but the cost of erecting utility poles can also be reduced.

[0003] However, in the current cable laying process, workers usually hold cable reels and lay the cables along the dug trenches. After laying the cables, they also need to manually backfill the soil. The entire cable laying operation is not only inefficient, but also very time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cable burying device and method for water conservancy and hydropower construction. This device can be used for the automatic pre-burying and backfilling of cables in hydropower projects, replacing the traditional manual cable burying and backfilling process, effectively improving the efficiency of cable burying and reducing the labor intensity of workers; moreover, it can effectively control and guide the position of the pre-buried cable, ensuring the quality of cable burying.

[0005] To achieve the aforementioned technical features, the present invention aims to provide an automatic cable-laying device for water conservancy and hydropower construction, comprising a frame for mounting the entire device; a plurality of rollers for supporting the movement of the entire device are installed at the bottom of the frame, and the rotation shafts of the rollers are connected to a first drive wheel via an intermediate transmission mechanism; the first drive wheel is vertically rotatable and mounted on the top of the frame, and the first drive wheel cooperates with a second drive wheel to clamp the water conservancy and hydropower cable and unwind it by rotational traction; a winding drum for storing the water conservancy and hydropower cable is provided on the top of the frame and on one side of the first drive wheel, and a wire guide device for guiding the water conservancy and hydropower cable is provided on the top of the frame and on the other side of the first drive wheel; a cable-laying device for burying the cable is provided on the frame and at the outlet end of the guide mechanism.

[0006] The rear end of the frame is fixedly equipped with a handle for moving the frame.

[0007] The intermediate transmission mechanism includes a worm gear mounted on a rotating shaft. The rotating shaft is rotatably supported at the bottom of multiple reinforcing hangers via bearings. The reinforcing hangers are fixed at the bottom of the vehicle frame. A vertical first fixed frame is rotatably mounted on one side of the worm gear. A worm wheel that meshes with the worm gear is fixed at the lower end of the first fixed frame. The first fixed frame is connected to a first drive wheel via a belt transmission mechanism.

[0008] The belt drive mechanism includes a drive wheel installed in the middle of the first fixed frame, and a second fixed frame rotatably mounted on the lower end face of the frame. The first drive wheel is fixed to the top of the second fixed frame and located on the upper end face of the frame. A driven wheel is fixed to the lower end of the second fixed frame. A transmission belt is installed between the driven wheel and the drive wheel, so that the drive wheel can drive the driven wheel to rotate, and the first drive wheel can rotate on the upper end face of the frame following the rolling of the roller.

[0009] The second drive wheel is slidably mounted on one side of the first drive wheel. A movable frame is horizontally slidably mounted on the upper end of the frame. One end of the upper surface of the movable frame is rotatably mounted on the second drive wheel. The end of the movable frame away from the second drive wheel extends out of the outer side of the frame and is fixed with a threaded cylinder. A first drive screw is rotatably mounted on the side of the frame. The first drive screw horizontally passes through the threaded cylinder, and a handle is fixed at the end of the first drive screw.

[0010] Two fixing lugs are symmetrically fixed on the upper end face of the frame away from the winding drum. A second drive screw is rotatably installed between the two fixing lugs. One end of the second drive screw extends out of the outside of the fixing lug and is fixed with a rotating handle. The wire guide is threaded onto the second drive screw and slides against the upper end face of the frame.

[0011] The wire guide device includes a movable block, the lower end face of which slides against the upper end face of the frame. The bottom of the movable block has a threaded hole through which the second drive screw thread passes, and a wire tube is fixed in the middle of the movable block. One end of the wire tube extends out of the frame, and the other end faces the middle of the frame and is fixed with a lead box.

[0012] An organic cover is fixed to the top of the frame and directly above the first and second drive wheels.

[0013] The buried wire device includes two movable plates rotatably mounted at one end of the rear of the vehicle frame. Multiple elastic elements are installed on the lower end face of each of the two movable plates. A bulldozer plate is fixed to the lower end of the multiple elastic elements. The ends of the two bulldozer plates away from the vehicle frame are inclined and intersected to form a triangular baffle structure for bulldozing and backfilling.

[0014] The method for laying water conservancy and hydropower cables using the aforementioned automatic cable-laying device includes the following steps: Step 1, excavation of the pit: Excavate trenches at locations where water conservancy and hydropower cables need to be laid; Step 2, Storage of water conservancy and hydropower cables: The water conservancy and hydropower cables that need to be buried are stored on the winding drum; Step 3, placement of the automatic wire burying device: The entire automatic cable-burying device is placed above the pit used for pre-burying water conservancy and hydropower cables so that it can move along the pit. Step 4, Automatic traction and unwinding of water conservancy and hydropower cables: The entire frame is moved manually. When the frame moves, the roller drives the rotating shaft to rotate. The rotating shaft meshes with the worm gear in the middle to drive the driving wheel in the middle of the first fixed frame to rotate. In conjunction with the transmission belt, the driving wheel drives the driven wheel to rotate, so that the first drive wheel can follow the driven wheel to rotate on the upper surface of the frame. By rotating the first drive screw, the threaded drum is driven to move on the upper end of the frame, thereby controlling the second drive wheel to cooperate with the first drive wheel, clamping the water conservancy and hydropower cable extending from the take-up drum, and cooperating with the rotation of the first drive wheel to pull out the cable on the take-up drum by rotation. Step 5, Pre-embedding of water conservancy and hydropower cables: At the same time, the second drive screw is rotated to drive the wire device to move on the frame, so that the wire device corresponds to the position of the pit, so that the water conservancy and hydropower cable can enter the wire tube through the lead box, and then be laid into the pit by the wire tube. Step 6, burying water conservancy and hydropower cables: Meanwhile, as the chassis continues to move, after the cable is laid into the pit by the guide wire device, the movable plate at the end of the chassis will use the bulldozer to backfill the soil dug on both sides of the pit, thus achieving the effect of pre-burying water conservancy and hydropower cables.

[0015] The present invention has the following beneficial effects: 1. This invention benefits from the cooperation of the frame, take-up drum, first drive wheel, second drive wheel, and conductor device. When the frame moves along the pit for pre-buried water conservancy and hydropower, the rotating shaft rotates with the movement of the rollers. This allows the worm gear to drive the drive wheel in the middle of the first fixed frame to rotate through meshing with the worm wheel. The drive wheel then drives the driven wheel to rotate through the transmission belt. This allows the first drive wheel to rotate with the driven wheel on the upper end of the frame. In this way, the second drive wheel works together to stretch the cable on the take-up drum through rotation during the cable clamping process, and allows the cable to pass through the conductor device and be laid into the pit.

[0016] 2. This invention uses a movable plate at the end of the vehicle frame to backfill the soil excavated on both sides of the pit with a bulldozer, achieving the effect of pre-burying water conservancy and hydropower cables, and is easy to use.

[0017] 3. Thanks to the design of the wire guide device, the position of the wire guide device for pre-embedding the cable can be controlled by adjusting the position of the wire guide device on the frame, resulting in good performance.

[0018] 4. The intermediate transmission mechanism described above can be used to transmit the power of the roller to the first drive wheel through the power transmission method of the worm gear, and then realize the automatic traction and unwinding of water conservancy and hydropower cables through the clamping cooperation between the first drive wheel and the second drive wheel.

[0019] 5. The belt drive mechanism described above can be used to transmit the power of the worm gear to the first drive wheel.

[0020] 6. The installation method of the second drive wheel described above can be used to adjust the distance between the second drive wheel and the first drive wheel, thereby achieving the clamping of water conservancy and hydropower cables, ensuring automatic clamping, and adapting to cables of different diameters.

[0029] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example 1: like Figure 1-6 An automatic cable burying device for hydropower construction includes a frame 1 for mounting the entire device; multiple rollers 2 are installed at the bottom of the frame 1 to support the movement of the entire device, and the rotating shafts 201 of the rollers 2 are connected to a first drive wheel 5 through an intermediate transmission mechanism; the first drive wheel 5 is vertically rotated and installed on the top of the frame 1, and the first drive wheel 5 cooperates with a second drive wheel 6 to clamp the hydropower cable and unwind it by rotational traction; a winding drum 3 for storing the hydropower cable is provided on the top of the frame 1 and on one side of the first drive wheel 5, and a guide wire device 9 for guiding the hydropower cable is provided on the top of the frame 1 and on the other side of the first drive wheel 5; a cable burying device is provided on the frame 1 at the outlet end of the guide mechanism. This device can be used for automatic pre-burying and backfilling of cables in hydropower projects, replacing the traditional manual cable burying and backfilling process, effectively improving the efficiency of cable burying and reducing the labor intensity of workers; moreover, it can effectively control the position of the pre-buried cable and ensure the quality of the burying. During operation, the roller 2 drives the intermediate transmission mechanism, which in turn drives the first drive wheel 5. The clamping action between the first drive wheel 5 and the second drive wheel 6 enables the automatic traction and unwinding of the hydropower cable. The conductor device 9 guides the hydropower cable to match the trench position. The cable burying device also enables the automatic burial of the hydropower cable.

[0031] Furthermore, a gripping part 102 for moving the frame 1 is fixedly mounted on one end of the rear end via a handle 101. The gripping part 102 facilitates the movement of the entire device, thereby providing the power for walking.

[0032] Furthermore, the intermediate transmission mechanism includes a worm gear 203 mounted on a rotating shaft 201. The rotating shaft 201 is rotatably supported at the bottom of multiple reinforcing hangers 202 via bearings, and the reinforcing hangers 202 are fixed to the bottom of the frame 1. A vertical first fixed frame 204 is rotatably mounted on one side of the worm gear 203. A worm wheel 205 meshing with the worm gear 203 is fixed at the lower end of the first fixed frame 204. The first fixed frame 204 is connected to the first drive wheel 5 via a belt transmission mechanism. This intermediate transmission mechanism transmits the power of the roller 2 to the first drive wheel 5 via the worm gear and worm wheel, thereby achieving automatic traction and unwinding of the hydropower cable through the clamping engagement between the first drive wheel 5 and the second drive wheel 6. During operation, as the frame 1 moves, the roller 2 drives the rotating shaft 201 to rotate. The rotating shaft 201 meshes with the worm wheel 205 via the worm gear 203 in the middle, driving the drive wheel 206 in the middle of the first fixed frame 204 to rotate.

[0033] Furthermore, the belt drive mechanism includes a drive wheel 206 mounted in the middle of the first fixed frame 204, and a second fixed frame 501 rotatably mounted on the lower end face of the frame 1. The first drive wheel 5 is fixed to the top of the second fixed frame 501 and located on the upper end face of the frame 1. A driven wheel 502 is fixed to the lower end of the second fixed frame 501. A transmission belt 503 is installed between the driven wheel 502 and the drive wheel 206, so that the drive wheel 206 can drive the driven wheel 502 to rotate, and the first drive wheel 5 can rotate on the upper end face of the frame 1 following the rolling of the roller 2. The belt drive mechanism described above can be used to transmit the power of the worm gear to the first drive wheel 5. During operation, the rotation of the drive wheel 206 will cooperate with the transmission belt 503 to drive the driven wheel 502 to rotate, so that the first drive wheel 5 can rotate on the upper end face of the frame 1 following the driven wheel 502.

[0034] Furthermore, the second drive wheel 6 is slidably mounted on one side of the first drive wheel 5. A movable frame 601 is horizontally slidably mounted on the upper end of the frame 1. One end of the upper surface of the movable frame 601 is rotatably mounted for the second drive wheel 6, and the end of the movable frame 601 away from the second drive wheel 6 extends outward from the frame 1 and is fixed with a threaded cylinder 602. A first drive screw 7 is rotatably mounted on the side of the frame 1, and the first drive screw 7 horizontally passes through the threaded cylinder 602. A handle is fixed to the end of the first drive screw 7. Through the above-described installation method of the second drive wheel 6, the distance between the second drive wheel 6 and the first drive wheel 5 can be adjusted, thereby achieving the clamping of hydraulic and hydropower cables to ensure automatic clamping and adaptability to cables of different diameters. During operation, the first drive screw 7 can be rotated to drive the threaded cylinder 602 to move on the upper surface of the frame 1, thereby controlling the second drive wheel 6 to cooperate with the first drive wheel 5 to clamp the hydraulic and hydropower cables extending from the take-up drum 3.

[0035] Furthermore, two fixing lugs 8 are symmetrically fixed to the upper end face of the frame 1 away from the winding drum 3. A second drive screw 801 is rotatably mounted between the two fixing lugs 8. One end of the second drive screw 801 extends outward from the fixing lug 8 and is fixed with a rotating handle. The wire guide device 9 is threaded onto the second drive screw 801 and slides against the upper end face of the frame 1. The above structure allows for adjustment of the position of the wire guide device 9.

[0036] Furthermore, the cable guide device 9 includes a movable block 901, the lower end face of which slides against the upper end face of the frame 1. The bottom of the movable block 901 has a threaded hole 902 through which the second drive screw 801 passes. A cable guide cylinder 903 is fixed in the middle of the movable block 901. One end of the cable guide cylinder 903 extends out of the frame 1, and the other end faces the middle of the frame 1 and is fixed with a lead wire box 904. The cable guide device 9 can be used to guide the cable, thereby burying it inside the trench. In the specific adjustment process, the second drive screw 801 is rotated to drive the cable guide device 9 to move on the frame 1, aligning the cable guide device 9 with the trench, allowing the cable to enter the cable guide cylinder 903 through the lead wire box 904, and then be guided into the trench by the cable guide cylinder 903.

[0037] Furthermore, a cover 4 is fixed to the top of the frame 1, directly above the first drive wheel 5 and the second drive wheel 6. The cover 4 protects the first drive wheel 5 and the second drive wheel 6, preventing debris from entering between them and thus ensuring the cable clamping is secure.

[0038] Furthermore, the cable burial device includes two movable plates 10 rotatably mounted at one end of the rear of the frame 1. Multiple elastic elements 1001 are installed on the lower end surfaces of both movable plates 10. A bulldozer plate 1002 is fixed to the lower end of each elastic element 1001. The ends of the two bulldozer plates 1002 away from the frame 1 intersect at an angle, forming a triangular baffle structure for backfilling. This cable burial device automatically fills the trench, thus achieving the cable burial operation. In the specific working process, as the frame 1 continues to move, after the cable is guided into the trench by the conductor device 9, the movable plates 10 at the end of the frame 1 use the bulldozer plate 1002 to backfill the soil excavated on both sides of the trench, achieving the effect of pre-burying water conservancy and hydropower cables. It is convenient to use.

[0039] Example 2: The method for laying water conservancy and hydropower cables using the aforementioned automatic cable-laying device includes the following steps: Step 1, excavation of the pit: Excavate trenches at locations where water conservancy and hydropower cables need to be laid; Step 2, Storage of water conservancy and hydropower cables: The water conservancy and hydropower cables that need to be buried are stored on the winding drum 3; Step 3, placement of the automatic wire burying device: The entire automatic cable-burying device is placed above the pit used for pre-burying water conservancy and hydropower cables so that it can move along the pit. Step 4, Automatic traction and unwinding of water conservancy and hydropower cables: The entire frame 1 is moved manually. When the frame 1 moves, the roller 2 drives the rotating shaft 201 to rotate. The rotating shaft 201 meshes with the worm gear 205 through the worm 203 in the middle to drive the driving wheel 206 in the middle of the first fixed frame 204 to rotate. In conjunction with the transmission belt 503, the driving wheel 206 drives the driven wheel 502 to rotate, so that the first drive wheel 5 can follow the driven wheel 502 to rotate on the upper surface of the frame 1. By rotating the first drive screw 7, the threaded drum 602 is driven to move on the upper end face of the frame 1, thereby controlling the second drive wheel 6 to cooperate with the first drive wheel 5, clamping the water conservancy and hydropower cable extending from the take-up drum 3, and cooperating with the rotation of the first drive wheel 5 to pull out the cable on the take-up drum 3 by rotation. Step 5, Pre-embedding of water conservancy and hydropower cables: At the same time, the second drive screw 801 is rotated to drive the wire device 9 to move on the frame 1, so that the wire device 9 corresponds to the position of the pit, so that the water conservancy and hydropower cable can enter the wire tube 903 through the lead box 904, and then be laid into the pit by the wire tube 903. Step 6, burying water conservancy and hydropower cables: Meanwhile, as the frame 1 continues to move, after the cable is laid into the pit by the guide wire device 9, the movable plate 10 at the end of the frame 1 will use the bulldozer plate 1002 to backfill the soil dug on both sides of the pit, thus achieving the effect of pre-burying water conservancy and hydropower cables.
