Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, specifically to a buried wire device for water conservancy and hydropower projects. Background Technology

[0002] During the construction of water conservancy and hydropower projects, it is often necessary to use cable burying devices to facilitate the placement and burial of underground cables. Existing cable burying devices are usually composed of components such as casters, push handles, carts, frames, and guide frames. They are easy to move during use, and the frame supports the cable rollers. The cable is buried by the guidance of the guide frame. However, since the cable is laid on the frame, there is usually a large frictional resistance between the cable and the frame, making rotation difficult. Moreover, since there are no limiters, the cable rollers are prone to loosening and falling, which is inconvenient to use.

[0003] Chinese utility model patent application number 202420849018.8 provides a wire burying device for water conservancy and hydropower projects. During use, the wire roller is easily supported and clamped between the connecting base and the rotating top cover, thus limiting its position and preventing it from easily coming loose during use. In addition, the wire roller is supported between the first and second drag-reducing wheels, so the resistance is small and the rotation is effortless. This makes it convenient to bury and lay wires during water conservancy and hydropower construction, and the device as a whole meets the usage requirements.

[0004] However, during the use of the above equipment, it was found that the size of the circular hole formed between the connecting base and the rotating top cover remained fixed. The diameter and length of the brackets at both ends of the rollers of different specifications were different. When the diameter of the bracket was larger than the circular hole, it was difficult to fix the roller in the circular hole. When the diameter of the bracket was smaller than the circular hole, it was difficult to keep the roller fixed in the circular hole. As a result, the roller wobbled or shifted during rotation, affecting the stability of operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a buried wire device for water conservancy and hydropower projects, which solves the problem mentioned in the background technology that the size of the circular hole formed between the connecting base and the rotating top cover remains fixed, and the diameter and length of the brackets at both ends of the wire rollers of different specifications are different, making it difficult to adapt the circular hole.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buried wire device for water conservancy and hydropower projects, comprising a movable base and a wire roller, with brackets at both ends of the wire roller, a fixed plate fixedly installed on the movable base, an adjustment assembly on the fixed plate, two sets of symmetrical movable frames on the adjustment assembly, a fixed assembly installed on the top of the movable frame, the fixed assembly including a C-shaped frame, a placement frame fixedly installed at the bottom of the frame, a pressure frame above the inner cavity of the frame, a guide rod fixedly installed on the top of the pressure frame, the guide rod penetrating the top of the frame, and a spiral rod rotatably installed on the top of the pressure frame, the spiral rod being spirally connected to the frame.

[0007] Preferably, the top of the placement rack is provided with a V-shaped groove, and rotating rollers are rotatably installed on both sides of the V-shaped groove.

[0008] Preferably, the pressure frame is an inverted placement frame with an inverted V-shaped pressure groove at its bottom, and a rotating roller is rotatably installed in the inverted V-shaped pressure groove of the pressure frame.

[0009] Preferably, the adjusting assembly includes a bidirectional threaded rod, which is damped and rotatably mounted on a fixed plate. Parallel sliding rods are arranged on both sides of the bidirectional threaded rod, and the sliding rods are fixed to the fixed plate. One end of the bidirectional threaded rod is connected to a rotating wheel.

[0010] Preferably, a movable block is fixedly provided at the bottom of the movable frame, and the movable block is slidably mounted on the slide rod and helically connected to the bidirectional threaded rod.

[0011] Preferably, the two sets of symmetrically arranged movable frames are symmetrically arranged on the helices at both ends of the bidirectional threaded rod.

[0012] This utility model provides a buried wire device for water conservancy and hydropower projects. It has the following beneficial effects:

[0013] (1) In this utility model, the placement frame supports the bottom of the roller bracket. When the spiral rod rotates, it drives the pressure frame to slide up and down along the guide rod, pressing the roller bracket onto the placement frame. Even if the diameter of the bracket is small or large, the roller can be installed stably by adjusting the distance between the pressure frame and the placement frame.

[0014] (2) The V-shaped groove at the top of the placement frame and the inverted V-shaped groove at the bottom of the pressure frame form an upper and lower clamping structure, which can closely fit the outer contour of the support at both ends of the roller. It can achieve stable positioning through the V-shaped structure for support with different diameters.

[0015] (3) This utility model adjusts the spacing of the moving frame by means of a bidirectional threaded rod, and combines the adjustable clamping structure of the placement frame and the pressure frame. This device can adapt to the installation requirements of various specifications of wire rollers. Whether it is a short-length and small-diameter wire roller or a long-size and large-diameter wire roller required for large-scale long-distance buried wire operations, it can be stably installed and used by adjustment, which greatly expands the application range of the equipment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4This utility model provides a buried wire device for water conservancy and hydropower engineering, including a movable base 1 and a wire roller 5. Both ends of the wire roller 5 are provided with brackets 51. A fixed plate 11 is fixedly installed on the movable base 1. An adjustment component 2 is provided on the fixed plate 11. Two sets of symmetrical movable frames 3 are provided on the adjustment component 2. A fixed component 4 is installed on the top of the movable frame 3. The fixed component 4 includes a C-shaped frame 41. A placement frame 42 is fixedly installed at the bottom of the frame 41. A pressure frame 43 is provided above the inner cavity of the frame 41. A guide rod 45 is fixedly installed on the top of the pressure frame 43. The guide rod 45 passes through the top of the frame 41. A spiral rod 44 is rotatably installed on the top of the pressure frame 43. The spiral rod 44 is spirally connected to the frame 41.

[0024] The top of the placement rack 42 is provided with a V-shaped groove 421, and rotating rollers 422 are rotatably installed on both sides of the V-shaped groove 421.

[0025] The pressure frame 43 is an inverted state of the placement frame 42, and its bottom is provided with an inverted V-shaped pressure groove. A rotating roller 422 is rotatably installed in the inverted V-shaped pressure groove of the pressure frame 43.

[0026] The adjusting assembly 2 includes a bidirectional threaded rod 22, which is damped and rotatably mounted on the fixed plate 11. Both sides of the bidirectional threaded rod 22 are provided with parallel sliding rods 23, which are fixed on the fixed plate 11. One end of the bidirectional threaded rod 22 is connected to a rotating wheel 21.

[0027] A movable block 31 is fixedly installed at the bottom of the movable frame 3. The movable block 31 is slidably mounted on the slide rod 23 and is helically connected to the bidirectional threaded rod 22.

[0028] Two sets of symmetrically movable frames 3 are symmetrically arranged on the helices at both ends of the bidirectional threaded rod 22.

[0029] Specifically, when installing the wire roller 5, the operator holds the rotating wheel 21 in the adjusting assembly 2. The surface of the rotating wheel 21 is designed with anti-slip texture to facilitate the application of force. Rotating the rotating wheel 21 clockwise drives the bidirectional threaded rod 22, which is fixedly connected to it, to rotate synchronously. Since the moving blocks 31 at the bottom of the two sets of moving frames 3 are respectively connected to the threads with different directions of rotation at both ends of the bidirectional threaded rod 22, and the moving blocks 31 are sleeved on the slide rod 23, the slide rod 23 plays a guiding role, restricting the moving blocks 31 to slide only along its axial direction. Therefore, when the bidirectional threaded rod 22 rotates, the two sets of moving frames 3 will slide back and forth along the slide rod 23, adjusting the distance between the moving frames 3 to the appropriate length for installing the wire roller 5.

[0030] Lift the wire roller 5 and place its bracket 51 stably on the V-groove 421 of the placement frame 42. At this time, the bottom of the bracket 51 at both ends of the wire roller 5 contacts the rotating roller 422 rotatably mounted on both sides of the V-groove 421. The rotating roller 422 can rotate freely, reducing the friction between the bracket 51 and the placement frame 42, which facilitates the subsequent adjustment of the rotation of the wire roller 5 for cable winding and unwinding.

[0031] The operator rotates the screw rod 44 in the fixing assembly 4, which engages with the pre-set internal threaded hole at the top of the frame 41. As the screw rod 44 rotates, it moves downward along the axial direction, causing the pressure frame 43, which is rotatably connected to the screw rod 44, to move downward synchronously. Since the guide rod 45 fixedly installed at the top of the pressure frame 43 passes through the guide hole at the top of the frame 41, the guide rod 45 plays a limiting and guiding role, ensuring that the pressure frame 43 can only move vertically up and down and will not deviate. When the pressure frame 43 moves downward, the inverted V-shaped pressure groove at its bottom gradually approaches the bracket 51 of the wire roller 5 until the rotating roller 422 in the inverted V-shaped pressure groove contacts the upper surface of the bracket 51, so that the placement frame 42 and the pressure frame 43 clamp and fix the bracket 51, ensuring that the wire roller 5 will not loosen or shift during the wire burying operation, thus completing the installation of the wire roller 5;

[0032] When disassembling the wire roller 5, the screw rod 44 is rotated in the opposite direction. The screw rod 44 and the frame 41 are screwed together, causing the screw rod 44 to move upward along the axial direction, which drives the pressure frame 43 to rise synchronously. Under the guidance of the guide rod 45, the pressure frame 43 moves upward smoothly. The rotating roller 422 in the inverted V-shaped pressure groove at the bottom of the pressure frame 43 gradually disengages from the support 51 of the wire roller 5 until the pressure on the support 51 is completely released. The wire roller 5 loses the clamping force from the vertical direction. The operator can directly lift the wire roller 5 from the V-shaped groove 421 of the placement frame 42 and remove it from the wire embedding device, thus completing the disassembly process of the wire roller 5. The spacing of the moving frame 3 can then be adjusted as needed.

[0033] The design of the bidirectional threaded rod 22 and the rotating wheel 21 allows for flexible adjustment of the spacing of the moving frame 3 to accommodate different lengths of the wire roller 5. The V-groove and inverted V-groove structures of the placement frame 42 and the pressure frame 43 can accommodate different diameter brackets 51, greatly expanding the device's compatibility with the specifications of the wire roller 5. Installation and disassembly are efficient and convenient, avoiding the problem of installation failure due to incompatible wire roller 5 dimensions.

[0034] Working principle: During installation, rotating the wheel 21 in the adjusting assembly 2 drives the bidirectional threaded rod 22 to rotate. Since the moving blocks 31 at the bottom of the two sets of moving frames 3 are respectively screwed to both ends of the bidirectional threaded rod 22, and under the guidance of the slide rod 23, the moving frames 3 will slide relative to or away from each other along the slide rod 23, adjusting the spacing of the moving frames 3 to a suitable length for the installation of the wire roller 5. Next, the wire roller 5 is placed on the V-groove 421 of the placement frame 42, with the bottom of the bracket 51 contacting the rotating roller 422. Subsequently, rotating the screw rod 44 in the fixing assembly 4 screws into the frame 41, driving the pressure frame 43 to move downward along the guide rod 45 until the inverted V-shaped pressure groove at the bottom of the pressure frame 43 presses against the bracket 51 of the wire roller 5 through the rotating roller 422, stabilizing the wire roller 5 and completing the installation.

[0035] During disassembly, rotate the screw rod 44 in the opposite direction to lift the pressure frame 43 upwards, releasing the clamping state on the bracket 51. At this time, the roller 5 loses its clamping force and can be directly lifted and removed from the placement frame 42, completing the disassembly.
