Abstract
Description
Technical Field
[0001] The utility model relates to the field of water pipe cutting and laying, and specifically refers to a cutting device for water pipe laying. Background Technique
[0002] In building construction, a water supply and drainage system almost needs to be arranged. The indoor and outdoor water supply and drainage systems are generally connected by sections of water pipes. Due to the routing of the water conveyance path, a standard PVC water pipe needs to be cut into an appropriate length.
[0003] PVC plastic water pipes are relatively easy to cut. In general water and electricity construction, when cutting water pipes, workers mostly adopt traditional methods. They place the water pipe above the ground, with part on the convex platform and part protruding from the convex platform. The cut part is exposed some above the convex platform, and then the cut part is on one side of the convex platform and is stepped on by the foot. Finally, a cutting machine is used for cutting. First of all, the water pipe is cylindrical. Just stepping on it with the foot cannot completely fix it. Moreover, during the cutting process, it is impossible for the personnel to ensure complete immobility, so the water pipe will have the opportunity to move. In addition, when the personnel maintain the posture of stepping on the water pipe with one foot to fix it, they have to bend down to hold the cutting equipment to cut the water pipe. The above two situations will both cause the cutting surface of the water pipe to be uneven, affecting the subsequent normal use of the water pipe. And as mentioned in the previous text, this complex operating posture, stepping on the round water pipe, the safety is not guaranteed. Therefore, a cutting device for water pipe laying is needed. Content of the Utility Model
[0004] I. Technical Problems to be Solved
[0005] The technical problem to be solved by the utility model is that when workers cut water pipes in a traditional way, the cutting effect and personnel safety cannot be guaranteed.
[0006] II. Technical Solution
[0007] To solve the above technical problems, the technical solution provided by the utility model is: a cutting device for water pipe laying, including a bracket, and a PVC water pipe is connected above the bracket.
[0008] Clamping mechanisms matched with the PVC water pipe are connected to both sides of the top of the bracket. The clamping mechanism includes a support rod. Both ends of the support rod are connected upward with a support plate. The support plate is connected and arranged inside the top of the bracket. The support rod is rotatably connected upward with a screw rod below the PVC water pipe. A screw hole matched with the screw rod is connected to the support rod. The top end of the screw rod is connected with a support. Clamping frames are rotatably connected to both sides of the support rod. The top end of the clamping frame is connected with a fastening end matched with the PVC water pipe. Driving rods are rotatably connected between both ends of the support and the clamping frames.
[0009] Further, a draw box is connected upward at the bottom of the bracket. Slide plates that cooperate with the draw box are connected to both sides of the bottom of the bracket. The draw box is used to receive the debris that falls from the sheared PVC water pipe above, preventing the debris from being scattered randomly all over the place, which is inconvenient to clean. Hooks - type sliders are provided above both ends of the draw box and are matched with the chutes at the top of the slide plates, facilitating the sliding in and out of the draw box. The slide plates fixed inside the bracket can also provide support for the draw box.
[0010] Further, bearing grooves that cooperate with the PVC water pipe are connected to both sides at the top of the bracket. The bearing grooves are arranged in a semi - circular arc groove shape at both ends of the bracket to assist in the placement of the PVC water pipe. Rubber blocks are connected to the fastening ends. The rubber blocks themselves have a certain elasticity and good friction, and the clamping surfaces are additionally provided with concave - convex surfaces to enhance the stability of clamping the PVC water pipe.
[0011] Further, a support shaft is connected to one side at the top of the bracket. A bushing is connected to the support shaft. The bushing and the support shaft are rotatably connected in a manner with a certain frictional resistance. A thermoplastic cavity that cooperates with the PVC water pipe is connected to one side of the bushing. A fixing plate is connected inside one side of the bottom of the bracket, and a controller associated with the thermoplastic cavity is connected to the fixing plate.
[0012] Further, a positioning frame that cooperates with the PVC water pipe is connected to one side of the top of the bracket where the thermoplastic cavity is located. When two PVC water pipes enter the hot - melt plastic connection through this device, it provides a direction - limiting effect for the water pipe that is not clamped in a direction other than its axial direction.
[0013] III. Beneficial Effects
[0014] The advantages of the present utility model compared with the prior art are as follows: By setting a bracket for carrying the water pipe, the position for first performing the cutting operation on the water pipe is reasonably raised, facilitating direct operation by personnel. Secondly, a clamping mechanism is arranged inside the bracket to firmly fix the water pipe. Compared with the traditional foot - stepping method, it can more effectively fix the water pipe, preventing the water pipe from moving during cutting or after fixation, which affects the cutting effect. In addition, two functions of hot - melt connection and cutting debris collection are added to the device, enhancing the functionality and practicality of the cutting device.

[0021] The following further details the present utility model with reference to the accompanying drawings
[0022] Embodiment 1
[0023] Combined with the attached Figures 1 - 5 , to solve the above technical problems, the technical solution provided by the present utility model is: a cutting device for water pipe laying, including a bracket 1, a PVC water pipe 2 is connected above the bracket 1, bearing grooves 3 that cooperate with the PVC water pipe 2 are connected to both sides of the top end of the bracket 1, the bearing grooves 3 are arranged in a semi-circular arc groove shape at both ends of the bracket 1 to assist in placing the PVC water pipe 2, a clamping mechanism that cooperates with the PVC water pipe 2 is connected to both sides of the top of the bracket 1, the clamping mechanism includes a support rod 6, support plates 5 are connected upward at both ends of the support rod 6, the support plates 5 are connected and arranged inside the top of the bracket 1, a screw 10 is rotatably connected upward under the PVC water pipe 2 on the support rod 6, a screw hole 13 that cooperates with the screw 10 is connected to the support rod 6, a support 9 is connected to the top end of the screw 10, clamping frames 7 are rotatably connected to both sides of the support rod 6 on the screw 10, a fastening end 11 that cooperates with the PVC water pipe 2 is connected to the top end of the clamping frame 7, a rubber block 12 is connected to the fastening end 11, the rubber block 12 itself has a certain elasticity and good friction, and the clamping surface is also additionally provided with concave and convex surfaces to enhance the stability of clamping the PVC water pipe 2, and a driving rod 8 is rotatably connected between both ends of the support 9 and the clamping frame 7
[0024] By setting up a rack with a clamping mechanism and placing the PVC water pipe 2 at a certain height, it is possible to cut the water pipe more conveniently, accurately, and safely. The clamping mechanism is divided into two identical parts. Each group of structures includes a support rod 6, which is fixedly connected to the inside of the bracket 1 through the support rod 6 and the support plate 5. Each set of clamping parts is arranged on both sides of the center of the bracket 1, as close to the center position as possible, but a certain space needs to be left between them. They do not necessarily have to be symmetrically arranged. By simply manually rotating the bolt below, the bolt drives the support 9 at its top to move up and down. When the support 9 moves downward, the two symmetrically designed clamping brackets 7 rotatably connected to the support rod 6 and the other end of the drive rod 8 are controlled by the drive rod 8, so that the fastening ends 11 at their tops approach each other to clamp and fasten the PVC water pipe 2. Conversely, the PVC water pipe 2 is loosened. Fixing the PVC water pipe 2 can avoid the jitter during operation caused by the unfixed position of the water pipe during cutting or the thermoplastic connection introduced below, which affects the cutting and joining effects and also reduces the risk of personal injury caused thereby.
[0025] Embodiment 2
[0026] Combined with the attached Figures 1 - 3 On the bottom of the bracket 1, a drawer 20 is connected upward. On both sides of the bottom of the bracket 1, sliding plates 19 are connected and are matched with the drawer 20. The drawer 20 is used to receive the debris that falls from the cut PVC water pipe 2 above, preventing the debris from being scattered all over the place and being inconvenient to clean. There are hook-shaped sliders above both ends of the drawer 20, which are matched with the chutes at the top of the sliding plates 19 to facilitate the sliding in and out of the drawer 20. The sliding plates 19 fixed inside the bracket 1 can also provide support for the drawer 20. On one side of the top of the bracket 1, a support shaft 14 is connected. An axle sleeve 15 is connected to the support shaft 14. The axle sleeve 15 and the support shaft 14 are rotatably connected in a way that has a certain frictional resistance. On one side of the axle sleeve 15, a thermoplastic cavity 16 matched with the PVC water pipe 2 is connected. On the top of the bracket 1, on one side of the thermoplastic cavity 16, a positioning bracket 4 matched with the PVC water pipe 2 is connected. This provides a direction limiting effect for one of the water pipes that is not clamped in addition to its axial direction when the two PVC water pipes 2 enter the hot melt plastic connection through this device. Inside one side of the bottom of the bracket 1, a fixing plate 18 is connected. A controller 17 associated with the thermoplastic cavity 16 is connected to the fixing plate 18.
[0027] The receiving mechanism for scraps generated by cutting is the extraction box 20 below, which effectively maintains the environmental hygiene of the operation site. By adding a thermoplastic mechanism with interconnected water pipes in the device, the functionality of this water pipe cutting equipment is enhanced, and it also provides a convenient, fast, and safe auxiliary measure for the subsequent thermoplastic connection step that is usually required after cutting the water pipes. The equipment for hot melt plastic connection of two water pipes is generally divided into a control instrument 17 and a thermoplastic cavity 16. The control instrument 17 is installed at a suitable position in the bracket 1, while the thermoplastic cavity 16 is arranged on one side of the top of the bracket 1 through a bushing 15 and a support shaft 14 that can fix the position with resistance and rotate relative to each other under excessive force. When not in use, it rotates on the support shaft 14 through the bushing 15 and is fixed at a certain position inside the bracket 1, which will not affect the water pipe cutting operation above and will not be exposed, preventing potential scalding of personnel. When in use, it is rotated to the top of the bracket 1. When it is horizontally placed, its inner cavity is exactly aligned with the central axis of the water pipe. For the two PVC water pipes 2 to be connected together, one is fixed on the bracket 1 through a clamping mechanism, and the other is position-limited by a positioning frame 4, preventing deviation at the connection or accidental change in the force application direction during thermoplastic auxiliary force application, which may cause the thermoplastic cavity 16 to hit the hand holding the water pipe by the operator, resulting in serious scalding. The thermoplastic cavity 16 needs to have a corresponding hand-held part for easy manual rotation. Currently, this part of general thermoplastic equipment usually has a heat insulation and anti-scalding touch structure, so it will not be described in detail here. It should be particularly noted that as an auxiliary function of this water pipe cutting device, its thermoplastic function is only applicable to two PVC water pipes 2 in a freely movable state. For other situations where the water pipes are fixed to the building, it can be selectively and reasonably used according to the on-site construction conditions.
[0028] In the specific implementation of the present utility model, when carrying out construction, decoration, and water and electricity construction, the PVC water pipe 2 can be cut by using this device. Place the PVC water pipe 2 to be cut into the bearing groove 3 at the top of the bracket 1, and try to position the water pipe cutting position in the middle of the bracket 1. Then, sequentially turn the screw 10 under the manual clamping mechanism, so that the fastening end 11 with a rubber pad firmly clamps the PVC water pipe 2. Then, use a cutting device to cut off the PVC water pipe 2. Loosen the clamping mechanism and take out the two cut water pipes. If one end of the PVC water pipe 2 needs to be trimmed, then it can be clamped by the clamping component on one side. The waste of the cut end will also fall into the lower extraction box 20. If, after cutting, other water pipes need to be connected to one of the cut PVC water pipes 2, first loosen the clamping component, take out the PVC water pipe 2 that does not need to be processed temporarily, turn the thermoplastic cavity 16 in the thermoplastic mechanism upward, align it with the water pipe, insert the PVC water pipe 2 to be connected into the thermoplastic cavity 16, and then hold the other water pipe to be connected. First, pass it through one end of the circular groove of the positioning frame 4, and then enter the thermoplastic cavity 16. The thermoplastic cavity 16 is heated by electricity to melt the plastic. After the ends of the two PVC water pipes 2 are melted and cooled, they are connected together. This belongs to the scope of the prior art, so the detailed principle thereof will not be described here. After the connection is completed, take out the overall pipe body. If the water pipe passing through the positioning frame 4 is a bent pipe, pull out the water pipe from one side of the positioning frame 4. If both parts to be connected are bent, then the thermoplastic function of this device is not applicable. When operating, this additional function in the device needs to be selected according to objective conditions.
[0029] The above describes the present utility model and its implementation manner. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if an ordinary person skilled in the art is inspired by it and designs a structural manner and an embodiment similar to this technical solution without creative work without departing from the creative concept of the present utility model, it shall fall within the protection scope of the present utility model.
