Description

Technical Field

[0001] This utility model relates to the field of power pipe cutting technology, and in particular to a power pipe cutting device for power construction. Background Technology

[0002] In power construction, power conduits (such as PVC pipes and MPP pipes) are key components used to protect cables and enable underground cable laying. Due to the complexity of construction scenarios (such as underground pipe networks, overhead lines, and substation renovations), power conduits need to be cut to specific lengths according to actual construction requirements. Therefore, cutting devices are commonly used equipment in power construction. Currently, commonly used power conduit cutting devices in power construction mainly include manual tools and portable electric cutting machines. These devices require manual handling of the pipe during cutting, which can easily lead to poor cut smoothness due to vibration, affecting subsequent pipe connections. Furthermore, because power construction involves large-scale laying projects, with hundreds of pipes cut per day, workers experience significant physical exertion. Therefore, the power construction field urgently needs a power conduit cutting device that is simple in structure, highly adaptable, highly precise, and safe.

[0003] Chinese patent document CN113977667B discloses a power pipe cutting device for power construction, including a workbench with a groove. A clamping mechanism is installed inside the groove. A vertical plate is installed on one side of the groove and on the workbench. A cutting mechanism is installed on the side of the vertical plate near the groove. The power pipe is fixed by the clamping mechanism, and the cutting mechanism performs a circular cut inside the power pipe. The cut power pipe has a flat cross-section, eliminating the need for secondary processing and improving work efficiency. The cutting process does not generate dust, which is beneficial to the health of workers. However, the above patent document still has the following defects in practice: The device contains four motors and five sets of gears, making it complex in structure, prone to failure, and costly to maintain. It uses a cutting tool for vertical cutting, which applies a downward force during the cutting process. The clamping force may not be sufficient to maintain the stability of the power tube, causing the power tube to shift or its end face to lift. The device lacks a simple unloading device, requiring manual removal and collection of the cut power tube. Summary of the Invention

[0004] The main objective of this invention is to provide a power pipe cutting device for power construction, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A power pipe cutting device for electric power construction includes a base. The upper end of the base is fixedly connected with a first supporting mechanism by bolts. The upper end of the base is fixedly connected with two conveying devices. The upper end of the first supporting mechanism is fixedly connected with a hydraulic cylinder. The telescopic end of the hydraulic cylinder is fixedly connected with a second supporting mechanism. The left and right ends of the second supporting mechanism are fixedly connected with two clamping and fixing mechanisms. The right end of the second supporting mechanism is rotatably connected with a cutting wire saw. The two conveying devices are located below the two clamping and fixing mechanisms. The upper end of the base is fixedly connected with a sliding device. The sliding device is located on the same side of the two conveying devices.

[0006] Preferably, the clamping and fixing mechanism includes a guide rod. A sleeve is slidably connected to the outer surface of the guide rod. A second metal plate is threadedly connected to the lower end of the sleeve. A third metal plate is fixedly connected to the outer surface of the guide rod. A spring is fixedly connected to the lower end of the third metal plate. The spring is sleeved on the outer surface of the guide rod. The lower end of the guide rod is fixedly connected with a second V-shaped clamping block. The spring is located between the third metal plate and the second V-shaped clamping block.

[0007] Preferably, the conveying device includes two fourth metal plates. A number of rollers are fixedly connected to the side where the two fourth metal plates are close to each other.

[0008] Preferably, the second supporting mechanism includes a support plate. Both the left and right sides of the support plate are fixedly connected to the second metal plate. The support plate is in a double-ji shape. A motor is installed on one of the plates on one side of the support plate. Mounting seats are fixedly connected to the other three plates by bolts. The three mounting seats are all rotatably connected with a rotating shaft.

[0009] Preferably, the cutting wire saw includes four wire rollers. A diamond wire cutting wire is wound around the outer surfaces of the four wire rollers. The four wire rollers are respectively installed on the transmissions of the outputs of three rotating shafts and the motor.

[0010] Preferably, the sliding device includes two sliding bases. A slider is slidably connected to the upper ends of the two sliding bases. A first metal plate is fixedly connected to the upper ends of the two sliders. A first V-shaped clamping block is installed on the side of the first metal plate close to the cutting wire saw. A groove is opened in the middle of the upper end of the sliding base.

[0011] Preferably, a rectangular pore is provided at the upper end of the base, located in the middle position between the two sliding bases, with a length consistent with that of the two sliding bases and a width consistent with the distance between the two sides of the two sliding bases close to each other.

[0012] Compared with the prior art, the present utility model has the following beneficial effects: 1. This device, through its designed clamping and fixing mechanism, utilizes the V-shaped structure of the V-shaped clamping block two, combined with the elastic force of the spring, to stably clamp power pipes of different diameters; at the same time, the sliding fit between the guide rod and the sleeve ensures that the V-shaped clamping block two is pressed vertically downwards without deviation, preventing displacement of the power pipe during cutting and ensuring the flatness of the cut. 2. This device features a wire saw with diamond wire wound around four rollers, combined with high-speed rotation driven by a motor, resulting in high cutting efficiency and a clean cut. The double-U-shaped support plate, mounting base, and rotating shaft work together to ensure the stability of the cutting process. 3. This device can precisely adjust the position of the V-shaped clamping block through the designed sliding device, so as to achieve precise cutting of the power pipe to a specific length, reducing the need for secondary processing. Moreover, the rectangular holes on the base facilitate the automatic falling of the cut power pipe into the collection box, simplifying the collection process. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1 like Figure 1 and Figure 5As shown, a power pipe cutting device for power construction includes a base 1. A support mechanism 4 is fixedly connected to the upper end of the base 1 by bolts. Two conveying devices 8 are fixedly connected to the upper end of the base 1. A hydraulic cylinder 5 is fixedly connected to the upper end of the support mechanism 4. A support mechanism 6 is fixedly connected to the telescopic end of the hydraulic cylinder 5. Two clamping and fixing mechanisms 7 are fixedly connected to the left and right ends of the support mechanism 6 for fixing the power pipe to be cut. A wire saw 3 is rotatably connected to the right end of the support mechanism 6. The two conveying devices 8 are located below the two clamping and fixing mechanisms 7. A sliding device 2 is fixedly connected to the upper end of the base 1. The sliding device 2 is located on the same side of the two conveying devices 8.

[0017] Specifically, such as Figure 2 As shown, the conveying device 8 includes two metal plates 81. Several rollers 82 are fixedly connected to the side of the two metal plates 81 that are close to each other. During implementation, the power pipe to be cut can be placed on the rollers 82. Due to the rolling property of the rollers 82, the operator can use a small force to move the power pipe on the two conveying devices 8 and convey it to the cutting position.

[0018] Furthermore, to secure the power conduit during cutting and prevent uneven cuts, please refer to... Figure 2 A clamping and fixing mechanism 7 was designed. The clamping and fixing mechanism 7 includes a guide rod 71, a sleeve 72 slidably connected to the outer surface of the guide rod 71, a metal plate 73 threadedly connected to the lower end of the sleeve 72, and a metal plate 74 fixedly connected to the outer surface of the guide rod 71. The function of the guide rod 71 and the sleeve 72 is to ensure that the metal plate 73 and the metal plate 74 move along the direction of the plumb bob. A spring 75 is fixedly connected to the lower end of the metal plate 74 and is sleeved on the outer surface of the guide rod 71. A V-shaped clamping block 76 is fixedly connected to the lower end of the guide rod 71, and the spring 75 is located between the metal plate 74 and the V-shaped clamping block 76.

[0019] Specifically, when hydraulic cylinder 5 is activated, the telescopic end of hydraulic cylinder 5 pushes support mechanism 2 6 downward, causing metal plate 2 73 to move downward along the outer surface of guide rod 71 until it reaches the position of metal plate 3 74, where it is given a downward thrust, causing metal plate 3 74 to move downward and compress spring 75, thereby causing V-shaped clamping block 2 76 to move downward. The V-shaped structure of V-shaped clamping block 2 76 can fix the power pipe; and due to the limitation of the internal space of sleeve 72, guide rod 71 cannot leave the internal space of sleeve 72, so that metal plate 2 73 and support mechanism 2 6 will not deviate from the vertical center line when moving downward, so that V-shaped clamping block 2 76 will not deviate when V-shaped pressing down, and will not cause the power pipe to shift before or during cutting.

[0020] In summary, when implementing this solution, first, place the power pipe to be cut on several rollers 82 of the conveying device 8. Due to the rolling characteristics of the rollers 82 themselves, the staff only needs to apply a small force to push the power pipe to move on the two conveying devices 8 and convey it to the preset cutting position. At this time, the support mechanism 4 threadedly connected to the upper end of the base 1 provides a stable foundation for the entire support system, and the hydraulic cylinder 5 fixed to its upper end starts to work. The telescopic end of the hydraulic cylinder 5 pushes the support mechanism 6 downward. The left and right sides of the support plate 61 of the support mechanism 6 are fixedly connected to the second metal plate 73 of the clamping and fixing mechanism 7. Therefore, the downward movement of the support mechanism 6 will synchronously drive the two clamping and fixing mechanisms 7 to act: the second metal plate 73 of the clamping and fixing mechanism 7 slides along the sleeve 72 on the outer surface of the guide rod 71. When the second metal plate 73 contacts the third metal plate 74 on the guide rod 71, the continuously downward moving second metal plate 73 will squeeze the spring 75 at the lower end of the third metal plate 74, causing the spring 75 to compress, and then driving the V-shaped clamping block 76 at the lower end of the guide rod 71 to move downward. Finally, the V-shaped clamping block 76 contacts the power pipe on the conveying device 8 and forms a firm clamping, preventing the power pipe from shifting during cutting and ensuring the stability of the cutting process.

[0021] Embodiment 2 As Figure 3 shown, the support mechanism 6 includes a support plate 61. The left and right sides of the support plate 61 are fixedly connected to the second metal plate 73. The support plate 61 is in a double inverted V shape. An electric motor 62 is installed on one of the plates on one side of the support plate 61, and mounting seats 63 are fixedly installed on the other three plates through bolts. Three mounting seats 63 are rotatably connected to a rotating shaft 64.

[0022] Furthermore, as Figure 3 shown, the wire saw ३ includes four wire rollers 32. One of the wire rollers 32 is connected to the output end of the electric motor 62 through a coupling. A diamond wire cutting wire 31 is wound around the outer surfaces of the four wire rollers 32 together. The four wire rollers 32 are respectively installed on the transmissions of the three rotating shafts and the output end of the electric motor 62.

[0023] Specifically, when the electric motor 62 is started during implementation, it drives one of the wire rollers 32 to rotate. Since the diamond wire cutting wire 31 is wound around the outer surfaces of all the wire rollers 32 together, the rotation of one of the wire rollers 32 drives all the wire rollers 32 and the diamond wire cutting wire 31 to rotate at high speed. At this time, the entire wire saw 3 is started, and the cutting of the power pipe can be realized.

[0024] Furthermore, to better obtain the power pipes of the required specific length, a device capable of measurement is needed, such as Figure 4As shown, the sliding device 2 includes two sliding bases 21, with sliders 22 slidably connected to the upper ends of the two sliding bases 21. The two sliders 22 can slide on the two sliding bases 21. A metal plate 23 is fixedly connected to the upper end of the sliders 22. A V-shaped clamp 24 is installed on the side of the metal plate 23 near the wire saw 3. The function of the V-shaped clamp 24 is to support the power pipe to be cut and prevent the other side from being clamped and tilted. A groove 25 is opened in the middle of the upper end of the sliding base 21. Scale lines are set on both sides of the upper part of the groove 25, and the 0 scale line is located directly below the diamond wire cutting line 31. When a specific length of power pipe is required, the sliding slider 22 drives the metal plate 23 and the V-shaped clamp 24 to move to a specific position and fix them with bolts to obtain the specific length.

[0025] Specifically, the power pipe is placed on the conveying device 8 and conveyed to the direction of the cutting wire saw 3. The other side of the power pipe is supported by the V-shaped clamp 24 to prevent it from tilting. The hydraulic cylinder 5 and the motor 62 are started, and the power pipe is clamped and fixed by the V-shaped clamp 76 of the clamping and fixing mechanism 7. At this time, the cutting wire saw 3 cuts the power pipe.

[0026] Furthermore, to facilitate the collection of the cut electrical conduits, such as... Figure 4 and Figure 5 As shown, the upper end of the base 1 has a rectangular opening, located in the middle of the two sliding bases 21. The length is the same as the two sliding bases 21, and the width is the same as the distance between the two sliding bases 21 on the side they are close to each other. In practice, a collection box can be placed directly below the rectangular opening of the base 1. The cut power pipe will fall into the collection box from the rectangular opening due to its own gravity.

[0027] In summary, during implementation, this solution first adjusts the sliding device 2 according to the required length of the power pipe: the slider 22 on the sliding base 21 is adjusted. The slider 22 drives the upper fixed metal plate 23 and the V-shaped clamping block 24 on one side of the metal plate 23 to move. After determining the position by the scale line on the upper groove 25 of the sliding base 21, the slider 22 is fixed. The power pipe to be cut is conveyed to the cutting position by the conveying device 8. The side of the pipe closest to the sliding device 2 is supported by the V-shaped clamping block 24 to prevent tilting caused by clamping on one side. Subsequently, the motor 62 of the support mechanism 2 6 is started. The output end of the motor 62 drives one of the wire rollers 32 of the cutting wire saw 3 to rotate through the coupling. Since the outer surfaces of the four wire rollers 32 are wrapped with diamond wire cutting wire 31, the rotation of one wire roller 32 will drive all wire rollers 32 and diamond wire cutting wire 31 to rotate at high speed, realizing the cutting action. The support plate 61 of the second support mechanism 6 is double-U-shaped, and the mounting seats 63 on the other three plates cooperate with the rotating shaft 64 to ensure the stable operation of the wire saw 3. After cutting, the cut power pipe falls into the pre-set collection box below through the rectangular hole between the two sliding bases 21 on the base 1 under its own gravity, completing the entire cutting and collection process.

[0028] It should be noted that the specific installation method, circuit connection method, and control method of the motor 62 and hydraulic cylinder 5 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
