Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to a prefabricated composite slab pipeline laying device. Background Technology

[0002] Prefabricated composite slabs are prefabricated floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. They are commonly used components in prefabricated buildings and generally consist of three parts: a precast base slab, slab joints, and a cast-in-place layer. The precast base slab includes precast concrete, truss reinforcement, and embedded parts. Traditional cast-in-place floor slab construction involves a large amount of manpower for formwork erection and concrete vibration. Prefabricated composite slabs reduce the workload of on-site formwork and some reinforcement binding, reducing quality risks caused by inconsistent skill levels among on-site construction workers. Some components of prefabricated composite slabs are prefabricated in the factory, and on-site work only requires hoisting and splicing. Then, conduits are pre-embedded and laid according to the designed pipeline route. During pipeline laying, the appropriate length is first cut, and then the conduits are bent directly by hand. If the length is insufficient or the roundness is out of shape, straight sections are used for repair. After laying, reinforcement binding is performed, and finally, the composite layer is poured to complete the construction.

[0003] Currently, the processes of cutting, bending, or repairing out-of-roundness during pipeline laying are quite complex. Manual bending makes it difficult to guarantee the curvature of the bend, and repairing out-of-roundness also leads to additional cutting and connecting work, making the operation quite cumbersome.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example:

[0030] This technical solution provides a device for laying pipelines in prefabricated composite slabs, mainly used for bending and cutting pipelines during pipeline laying. (Refer to...) Figure 1-7 The device includes a housing 1, a handle 3, and a power supply 2. The power supply 2 uses a general-purpose lithium battery. The front end of the housing 1 is provided with a mounting part, and the mounting part is movably connected to a mold head 9. The mold head 9 is provided with multiple shaping grooves 6. The grinding head is a quarter circle and has extensions at both ends. The shaping grooves 6 also extend to the two extensions according to the same size. One end of the mounting part is provided with multiple fixing grooves 15. The cross-section of the fixing grooves 15 and the shaping grooves 6 is a semi-circular structure. When they are fitted together, they form a round hole. In this way, the fixing grooves 15 and the shaping grooves 6 can be used to clamp and fix the tube by matching the outer diameter of the tube. After clamping, it can prevent the tube from sliding when bending and can also prevent abnormal deformation of the stressed parts.

[0031] The specific technical solution is as follows: A bracket 7 is installed on the side wall of the housing 1. A roller 5 is rotatably connected to the bracket 7. Multiple annular grooves that cooperate with the shaping groove 6 are opened on the shaft wall of the roller 5. A power mechanism is installed inside the housing 1. The power mechanism drives the bracket 7 to move, causing the roller 5 to compress the fixed wire tube in the shaping groove 6 on the die head 9, resulting in bending deformation. The power mechanism includes a guide tube 18. A lead screw 21 is sleeved inside the guide tube 18. An internally threaded tube 19 is threaded onto the rod wall of the lead screw 21. The internally threaded tube 19 is fixed to one end of the guide tube 18. Inside the housing 1... A geared motor 20 is fixedly connected, and the output end of the geared motor 20 is fixedly connected to one end of the lead screw 21. One side of the housing 1 is sleeved with the guide tube 18 through a round hole. A push rod 23 is fixedly connected to the bracket 7, and the push rod 23 is fixedly connected to one end of the guide tube 18. Two guide sleeves 13 are sleeved on the tube wall of the guide tube 18. One guide sleeve 13 is fixed to the upper inner wall of the housing 1, and the other guide sleeve 13 is fixedly connected to one side of the mounting part. A cylinder 22 is slidably connected inside the guide tube 18, and the cylinder 22 is fixedly connected to one end of the lead screw 21.

[0032] Guide rails 12 are fixedly connected to both sides of the housing 1. The side wall of the bracket 7 is slidably connected to the guide rails 12 through guide grooves. This is especially useful for bending galvanized pipes with a wall thickness of 0.8-2mm. The cooperation between the guide rails 12 and the guide grooves on the bracket 7 can increase the stability of the roller 5. The center of the roller 5 is connected to the main shaft through a round hole. The main shaft is rotatably connected to the round hole on the roller 5 through ball bearings. The two ends of the main shaft are fixed to the bracket 7.

[0033] This technical solution uses a geared motor 20 as the power source to directly drive the lead screw 21 to rotate. When the lead screw 21 rotates, it drives the internal threaded tube 19 to move the guide tube 18. The movement of the guide tube 18 drives the push rod 23 to move the bracket 7. When the bracket 7 moves, it drives the roller to squeeze the tube to be bent. In this way, the tube can be bent arbitrarily within the range of 0-90°. Moreover, when bending, the shaping groove 6 on the die head 9 supports the bending part of the tube to avoid abnormal deformation during bending.

[0034] Another technical solution of this invention is that a drive assembly is installed inside the housing 1. The drive assembly is used to directly drive the die head 9 to move and clamp and fix the pipeline. The drive assembly consists of an electric push rod 14 and a brake frame 10. One end of the housing 1 has a guide hole 16. One end of the brake frame 10 passes through the guide hole 16 and is provided with a fixing part 17. The fixing part 17 is fixedly connected to the die head 9 by bolts. The other end of the brake frame 10 is fixedly connected to the output end of the electric push rod 14. The electric push rod 14 can directly drive the brake frame 10 to move the die head 9 through the fixing part 17. At this time, the pipeline can be placed into the corresponding fixing groove 15. Then, by starting the electric push rod 14, the die head 9 is directly moved to fit against one end of the mounting part. At this time, the shaping groove 6 on the die head 9 cooperates with the fixing groove 15 to clamp the pipeline. Moreover, when the pipeline has collapsed deformation, excessive bending, or deformation at the pipe opening, etc., it is out of round. The pipeline can also be placed in the corresponding position for clamping. The pressure of the die head 9 can be used to quickly repair the out-of-round parts.

[0035] Furthermore, the mounting section is fixedly connected to two fixing blocks 4. Each fixing block 4 has an arc-shaped groove on one side to accommodate the conduit. One side of the fixing block 4 is flush with one side of the housing 1. A cutter 8 is fixedly connected to one side of the bracket 7. The cutter 8 is mainly used to cut plastic tubes with a thickness of 1.2-2.5mm. The cutter 8 is provided with an arc-shaped cutting edge and a spike at the arc-shaped cutting edge. When it contacts the conduit, the spike first contacts the conduit and can then be inserted into the conduit. After that, it extends from the middle to both sides. In this way, the cutter 8 can quickly penetrate into the conduit and cut the conduit.

[0036] Handle 3 is located at the upper end of housing 1, and two push switches 11 are installed on handle 3. One push switch 11 is used to control the geared motor 20 to start the power mechanism, and the other is used to start the electric push rod 14 to start the drive component. The auxiliary electronic components required are matched according to the existing technology, which will not be elaborated on here, nor will they be improved in this technical solution. Power supply 2 is located at the upper end of housing 1 and at the rear of handle 3, so that it can match the weight of the device and make the weight of the front and rear ends similar.

[0037] Through this improvement, compared with the traditional three-point pipe bender or manual pipe bender, this technical solution can bend the pipe by first fixing it and then bending it. During bending, a fixed point is used for fixing, and a linearly advancing roller 15 applies force to make the pipe deform around the die head 9, thereby achieving the bending of the pipe. The bending angle and arc are easy to control. At the same time, the movable die head 9 can be used to repair out-of-round pipes and can also cut plastic pipes, making it convenient for construction workers to use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
