Description

Technical Field

[0001] This invention relates to the field of buried wire construction technology, and more specifically, to a buried wire device and its usage method. Background Technology

[0002] During civil construction, it is often necessary to lay, replace, and inspect cables underground. In the process of burying cables, trenching machines are often used to first open trenches in the ground before burying the cables.

[0003] While most existing cable-laying devices can perform trenching and cable burial simultaneously, the trench depth can only be set before construction and cannot be adjusted during construction. Consequently, the burial depth cannot be adjusted according to the specific conditions of the construction site. Furthermore, the cable cannot be laid into the trench independently during burial; manual assistance is required, which poses certain safety hazards and is not conducive to improving efficiency. Therefore, further innovation and improvement of existing technologies are needed.

[0004] Utility model patent CN208971048U discloses a multi-functional cable laying vehicle frame. This frame can automatically lift and transport the central shaft and cable reel together to a suitable position on the main body of the frame. However, this frame can only lay cables and cannot perform grooving operations, thus failing to simplify the work process. Utility model patent CN210658502U discloses an underwater trenching machine adjustment device. This device effectively solves the problem of shallow trenching depth caused by the limited adjustment of the pitch angle in existing trenching machines. However, this device can only adjust the trenching depth and does not have the relevant structure for laying cables. Cable laying still needs to be performed separately after trenching. At the same time, it cannot solve the problem of soil accumulation during trenching, which affects the forward movement. Utility model patent CN218201425U provides a cable processing and laying mechanism. This mechanism reduces the difficulty of taking the cable reel off and placing it from the support. However, this mechanism cannot achieve simultaneous trenching and cable laying. Summary of the Invention

[0005] To overcome the technical problems in the prior art, this invention provides a wire burying device and its usage method. This device enables simultaneous trenching and wire burying, boasts a high degree of automation, avoids the tedious manual operation of wire burying, and allows for flexible adjustment of trench depth during the trenching process, meeting the needs of wire burying construction in different scenarios. This significantly improves construction efficiency and safety.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A wire embedding device includes a slotted chain assembly, a connecting plate, a hydraulic cylinder, and a top plate. A support plate and a side plate are provided on the lower surface of the top plate. The support plate and the side plate are both perpendicular to the top plate. Rotary cylinders are symmetrically arranged at both ends of one side of the slotted chain assembly. The two rotating cylinders are rotatably connected to the support plate and the side plate, respectively. The connecting plate is fixedly connected to the rotating cylinders. The top of the hydraulic cylinder is rotatably connected to the top plate through an ear plate. The bottom movable end of the hydraulic cylinder is hinged to the end of the connecting plate. A cable reel bracket is provided on the top plate, and a cable reel is provided on the cable reel bracket. A cable embedding assembly is provided at the rear end of the top plate, and a support plate is provided at the front end of the top plate. A diesel engine is provided on the support plate and is connected to the slotted chain assembly. A set of moving wheels is rotatably provided on the support plate, and a pull handle is provided at the front end of the top plate. A controller is provided on the pull handle and is electrically connected to a hydraulic cylinder.

[0007] The slotted chain assembly includes two chain plates, sprockets, and a chain arranged side by side. There are two sprockets, which are respectively located on both sides of the chain plate. The chain is connected between the two sprockets for transmission. Multiple slotting cutters are equidistantly arranged on the outer surface of the chain. The rotating drum is fixedly connected to the outer side of the chain plate.

[0008] The output end of the diesel engine is connected to the sprocket via a drive belt.

[0009] The rear end of the top plate is provided with a set of support wheels, and two sets of support wheels are symmetrically arranged on the lower surface of the top plate.

[0010] The wire embedding assembly includes an inclined plate, an extension plate, a front end plate, a motor, and a top end plate. The inclined plate and the motor are mounted on the top end plate. The extension plate is located at the rear end of the inclined plate and is connected to the inclined plate. The front end plate is located on the side of the extension plate away from the inclined plate. The top end plate is located on the top of the inclined plate. A first wire feeding wheel group and a second wire feeding wheel group are respectively mounted on the front end plate and the top end plate. The second wire feeding wheel group is connected to the motor via a transmission belt. The first wire feeding wheel group and the second wire feeding wheel group are connected via a transmission belt. The first wire feeding wheel group and the second wire feeding wheel group have the same structure. The motor is electrically connected to the controller.

[0011] The second wire feeding wheel assembly includes a conveying roller and an auxiliary roller. The conveying roller is rotatably mounted on the top plate. The auxiliary roller has a rotating shaft at both ends. The top plate has a movable groove. The rotating shaft is movably mounted in the movable groove and is connected to a clamping assembly.

[0012] The clamping assembly includes a fixed block, an adjusting screw, and a bushing. The fixed block is fixedly disposed on both sides of the top plate and has threaded holes. The adjusting screw is threadedly connected to the threaded holes of the fixed block. The rotating shaft is inserted into the bushing. The bottom end of the adjusting screw is rotatably connected to the top of the bushing. A screw knob is rotatably connected to the fixed block and sleeved on the outside of the adjusting screw. The screw knob is threadedly connected to the adjusting screw.

[0013] A helical rod is provided on the side plate at the position corresponding to the slotted chain assembly. The helical rod is connected to the sprocket drive, and an arc-shaped baffle is provided around the helical rod.

[0014] A support plate is fixedly installed on the side plate, and a battery is installed on the support plate. The battery is electrically connected to the controller and the motor.

[0015] A method of using a buried wire device includes the following steps: S1. Start the diesel engine to drive the slotted chain assembly to rotate. Start the hydraulic cylinder through the controller to push the connecting plate with its moving end, which drives the drum to rotate. The angle position of the slotted chain assembly can be adjusted, thereby adjusting the slotting depth. S2. After the grooving chain assembly contacts the ground, it begins to groove. Use the pull handle to pull the entire device along the grooving direction. S3. The controller operates the motor to rotate, and the motor drives the second wire feeding wheel group to rotate. The conveying roller, together with the auxiliary roller, begins to convey the cable wrapped on the outer surface of the cable reel so that it is laid into the trench.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention activates two hydraulic cylinders, causing their push rods to drive a connecting plate. The connecting plate then drives a rotating drum. Since the two rotating drums are connected to the support plate and the side plate respectively via bearings, the slotted chain assembly will rotate with the rotating drum, thereby adjusting the slotting depth of the slotted chain assembly to meet different wire embedding depth requirements.

[0017] When the grooving chain assembly starts moving, it creates a trench in the ground. The soil generated during trenching is thrown towards the direction of the auger by the grooving cutter. Since the auger rotates at high speed with a sprocket, it can transport the soil to the side of the trench once it comes into contact with the soil. By setting up an arc-shaped baffle, it can also prevent soil from splashing onto the battery. The overall structure can prevent soil from accumulating under the device during the grooving process, which would make the device difficult to move.

[0018] During the grooving process, starting the motor drives the rotating shaft to rotate, which in turn drives the conveyor rollers fixedly connected to the shaft to rotate. The conveyor rollers and auxiliary rollers work together to convey the cable, so the cable can be conveyed to the front end of the grooving chain assembly. Due to gravity, the output cable can be laid into the grooved trench. The overall structure does not require additional manual assistance in laying the cable, allowing grooving and cable laying to be carried out simultaneously. This not only improves efficiency but also eliminates the need for personnel to approach the grooving chain to assist in laying the cable, thus improving construction safety.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1 to 8 As shown, a wire embedding device includes a slotted chain assembly 1, a connecting plate 3, a hydraulic cylinder 4, and a top plate 7. A support plate 5 and a side plate 6 are provided on the lower surface of the top plate 7. The support plate 5 and the side plate 6 are both perpendicular to the top plate 7. Rotary cylinders 2 are symmetrically arranged at both ends of one side of the slotted chain assembly 1. The two rotating cylinders 2 are rotatably connected to the support plate 5 and the side plate 6, respectively. The connecting plate 3 is fixedly connected to the rotating cylinder 2. The top of the hydraulic cylinder 4 is rotatably connected to the top plate 7 through an ear plate 13. The bottom movable end of the hydraulic cylinder 4 is hinged to the end of the connecting plate 3. When the two hydraulic cylinders 4 are activated, their push rod ends can drive the connecting plate 3. The connecting plate 3 drives the rotating cylinders 2. Since the two rotating cylinders 2 are respectively connected to the support plate 5 and the side plate 6 through bearings, the slotted chain assembly 1 will rotate with the rotating cylinders 2, thereby adjusting the slotting depth of the slotted chain assembly 1 to meet different wire embedding depth requirements.

[0023] A cable reel bracket 8 is installed on the top plate 7, and a cable reel 9 is installed on the cable reel bracket 8. A wire embedding assembly 12 is installed at the rear end of the top plate 7, and a support plate 10 is installed at the front end of the top plate 7. A diesel engine 11 is installed on the support plate 10 and connected to the grooving chain assembly 1. A set of movable wheels 24 is rotatably installed on the support plate 10. A pull handle 22 is installed at the front end of the top plate 7, and a controller 23 is installed on the pull handle 22. The controller 23 is electrically connected to the hydraulic cylinder 4. The controller 23 controls the extension and retraction of the hydraulic cylinder 4, thereby controlling the grooving depth of the grooving chain assembly 1. The grooving depth can be flexibly adjusted during grooving construction to meet the construction requirements of complex terrain. The movable wheel set 24 enables the device to move. After the operator sets the grooving construction parameters through the controller 23, he faces away from the controller 23, holds the pull handle 22, and pulls the device to perform grooving operations. The wire embedding assembly 12 can synchronously lay the wire in the already grooved groove.

[0024] Preferably, the slotted chain assembly 1 includes two chain plates 101 arranged side by side, sprockets 102 and chain 103. There are two sprockets 102, which are respectively arranged on both sides of the chain plate 101. The chain 103 is connected between the two sprockets 102 for transmission. Multiple slotting cutters 104 are equidistantly arranged on the outer surface of the chain 103. The rotating drum 2 is fixedly connected to the outer side of the chain plate 101.

[0025] Preferably, the diesel engine 11 is connected to the sprocket 102 via a transmission belt. When the diesel engine 11 is started, its output end drives one of the sprockets 102 to rotate. The sprocket 102 has concentric shafts on both sides, which extend through the rotating drum 2. The transmission belt is connected to the extended shafts, and then the chain 103 rotates. The chain 103 drives multiple grooving cutters 104 to circulate. The cutting head of the grooving cutter 104 is made of manganese steel. When it contacts the ground, it begins to groove. The manganese steel material gives it good hardness and can easily crush stones in the soil.

[0026] Preferably, a support wheel assembly 25 is provided at the rear end of the top plate 7, and two sets of support wheel assemblies 25 are symmetrically arranged on the lower surface of the top plate 7. The support wheel assembly 25 is fixed to the lower part of the top plate 7 by a triangular frame, providing stable support for the overall movement of the device.

[0027] Preferably, the cable laying assembly 12 includes an inclined plate 121, an extension plate 125, a front end plate 126, a motor 127, and a top end plate 128. The inclined plate 121 and the motor 127 are mounted on the top plate 7. The extension plate 125 is located at the rear end of the inclined plate 121 and is connected to the inclined plate 121. The front end plate 126 is located on the side of the extension plate 125 away from the inclined plate 121. The top end plate 128 is located at the top of the inclined plate 121. A first cable feeding wheel set and a second cable feeding wheel set are respectively mounted on the front end plate 126 and the top end plate 128. The second cable feeding wheel set is connected to the motor 127 via a transmission belt. The first cable feeding wheel set and the second cable feeding wheel set are connected via a transmission belt. The first cable feeding wheel set and the second cable feeding wheel set have the same structure. The motor 127 is electrically connected to the controller 23. The motor 127 drives the first cable feeding wheel set and the second cable feeding wheel set to rotate, conveying the cable on the cable reel 9 into the trench, completing the cable laying operation.

[0028] Preferably, the second wire feeding wheel group includes a conveying roller 123 and an auxiliary roller 124. The conveying roller 123 is rotatably mounted on the top plate 128. The auxiliary roller 124 is provided with a rotating shaft 122 at both ends. The top plate 128 is provided with a movable groove. The rotating shaft 122 is movably mounted in the movable groove. The rotating shaft 122 is connected to a clamping assembly.

[0029] Preferably, the clamping assembly includes a fixed block 16, an adjusting screw 17, and a bushing 18. The fixed block 16 is fixedly disposed on both sides of the top plate 128. The fixed block 16 has threaded holes. The adjusting screw 17 is threadedly connected to the threaded holes of the fixed block 16. The rotating shaft 122 is inserted into the bushing 18. The bottom end of the adjusting screw 17 is rotatably connected to the top of the bushing 18. A screw knob 19 is rotatably connected to the fixed block 16 and sleeved on the outside of the adjusting screw 17. The screw knob 19 is threadedly connected to the adjusting screw 17. Rotating the screw knob 19 can drive the screw 17 to rise and fall. The screw 17 drives the bushing 18, which in turn drives the rotating shaft 122. The rotating shaft 122 drives the auxiliary roller 124, thus adjusting the distance between the conveying roller 123 and the auxiliary roller 124. This facilitates the cable to be inserted between the conveying roller 123 and the auxiliary roller 124. Then, the screw knob 19 can be adjusted again so that the conveying roller 123 and the auxiliary roller 124 can be in close contact with the outer surface of the cable, thereby realizing the conveying of the cable.

[0030] Preferably, a helical rod 14 is provided on the side plate 6 at the position corresponding to the slotted chain assembly 1. The helical rod 14 is connected to the sprocket 102 for transmission, and an arc-shaped baffle 15 is provided around the helical rod 14. When the sprocket 102 is driven by the diesel engine 11, the helical rod 14 also rotates at high speed. Once the helical rod 14 comes into contact with the soil, it can transport the soil to the side of the device, thus avoiding the situation where the soil accumulates under the device during the slotting process, making the device difficult to move. By setting the arc-shaped baffle 15, splashed soil can be intercepted, allowing the soil to be transported to the side of the trench by the helical rod 14, and the arc-shaped baffle 15 can prevent soil from splashing onto the outer surface of the battery 21.

[0031] Preferably, a support plate 20 is fixedly mounted on the side plate 6, and a battery 21 is mounted on the support plate 20. The battery 21 is electrically connected to the controller 23 and the motor 127. The battery 21 provides power to the motor 127 and the controller 23.

[0032] A method of using a buried wire device includes the following steps: S1. Start the diesel engine 11 to drive the slotted chain assembly 1 to rotate. Start the hydraulic cylinder 4 through the controller 23 to push the connecting plate 3 with its movable end, which drives the rotating drum 2 to rotate. The angle position of the slotted chain assembly 1 can be adjusted, thereby adjusting the slotting depth. S2. After the grooving chain assembly 1 contacts the ground, it begins to groove. Use the pull handle 22 to pull the entire device to move along the grooving direction. S3. The controller 23 operates the motor 127 to rotate, the motor 127 drives the second wire feeding wheel group to rotate, and the conveying roller 123, together with the auxiliary roller 124, begins to convey the cable wrapped on the outer surface of the cable reel 9 so that it is laid into the trench.

[0033] In use, the device is first moved to the work site. Then, the diesel engine 11 is started to drive the grooving chain assembly 1 to rotate. Subsequently, the controller 23 starts the hydraulic cylinder 4, causing its push rod end to drive the connecting plate 3. The connecting plate 3 drives the rotating drum 2, causing the grooving chain assembly 1 to rotate with the rotating drum 2. This allows adjustment of the grooving depth of the grooving chain assembly 1. Pulling the handle 22 moves the entire device to perform grooving. During the grooving process, the controller 23 starts the motor 127 to drive the rotating shaft 122 to rotate, which in turn drives the conveying roller 123, which is fixedly connected to the rotating shaft 122, to rotate. Because the cable is tightly attached to the arc-shaped groove of the conveying roller 123 and the auxiliary roller 124, the cable can be conveyed and laid in the grooved trench. The overall structure does not require additional manual assistance in laying the cable, improving efficiency. During the grooving process, the grooving depth of the grooving chain assembly 1 can be flexibly adjusted.

[0034] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
