Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protection pipe production, specifically to a MPP power cable protection pipe production guiding device. BACKGROUND

[0002] In today's engineering construction field, especially in the projects involving power, communication and other pipeline laying, MPP (modified polypropylene) material has been widely used due to its superior performance. The protection pipe made of MPP provides a reliable protective barrier for various cables and optical cables, ensuring the stable operation of the line.

[0003] With the development of society and the increasing awareness of environmental protection, non-excavation power pipe engineering has emerged, and MPP protection pipe plays a key role. This construction technology abandons the traditional mode of large excavation, and skillfully builds a pipeline laying path underground through directional drilling and pipe jacking, etc., to minimize the disturbance to the ground environment. Whether in the historical and cultural heritage protection area, densely populated and bustling downtown area, farmland protection area where crops grow, under the highway with heavy traffic, or the bottom of the river with turbulent water flow, MPP non-excavation construction can perform well, avoiding the restrictions of complex ground surface environment and successfully laying pipelines.

[0004] However, in the subsequent process after the extrusion molding of MPP cable pipe, the guiding device link has obvious shortcomings. At present, most of the protection pipe guiding devices on the market are designed and manufactured according to fixed pipe diameter specifications, and their adaptive diameter range is extremely narrow. Once the engineering requirements change, the existing guiding device cannot meet the requirements. The construction team has to stop the work, spend a lot of time to disassemble the original guiding device, find the equipment that adapts to the new pipe diameter from the warehouse, and re-install and debug it. This process not only wastes a lot of construction time and delays the construction period, but also causes the guiding device components to bear additional stress, accelerates wear and tear, and causes frequent problems such as loose connection, decreased precision of key transmission components, etc. This greatly increases the replacement frequency and maintenance cost of the equipment, which becomes a major obstacle to the efficient production and wide application of MPP protection pipe. Therefore, we propose a MPP power cable protection pipe production guiding device to solve the above problems. CONTENT OF THE UTILITY MODEL

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Embodiment: as Figures 1-5The utility model provides a kind of MPP electric power cable protection pipe production guiding device, including guide pipe 1, support seat 101 is fixedly connected in guide pipe 1 bottom, protection pipe body 2 is inserted in guide pipe 1 pipe, control assembly 3 is provided in guide pipe 1 inside, control assembly 3 includes multiple assembly slots 301, assembly slot 301 is opened in guide pipe 1 inner wall, multiple assembly slots 301 are evenly distributed around guide pipe 1 axis, two sides of assembly slot 301 inner wall are fixedly connected with fixed cylinder 302, two sides fixed cylinder 302 are distributed along assembly slot 301 axis symmetry, rotation roller 303 is built-in in assembly slot 301, rotation roller 303 two ends extend to two sides fixed cylinder 302, rotation roller 303 two ends are rotationally connected with the bottom of fixed cylinder 302 inner cavity, rotation roller 303 two ends are sleeved with coil spring 304, coil spring 304 is placed in fixed cylinder 302, one end of coil spring 304 is fixedly connected with the inner wall of fixed cylinder 302, the other end of coil spring 304 is fixedly connected with the surface of rotation roller 303, when there is no protection pipe body 2 insertion guide pipe 1, rotation roller 303 is under the action of coil spring 304 in initial position. One end of coil spring 304 is fixed in the inner wall of fixed cylinder 302, the other end is fixed on the surface of rotation roller 303, so that rotation roller 303 has a rotation tendency to make coil spring 304 tighten, when connecting seat 306 is hinged with movement seat 305 by positioning pin 308, guide plate 309 is also in corresponding initial position, multiple guide plates 309 are waiting for the insertion of protection pipe body 2 and are surrounded in guide pipe 1.

[0027] Further, the surface of the rotating roller 303 is sleeved with a moving seat 305, one end of the moving seat 305 is fixedly connected with the rotating roller 303, the end of the moving seat 305 close to the center of the guide pipe 1 is provided with a connecting seat 306, one side of the assembly groove 301 is provided with an embedded groove 311 for facilitating the moving seat 305 to enter under force, the side of the connecting seat 306 close to the moving seat 305 is provided with a connecting groove 307, the moving seat 305 is rotationally connected with the groove wall of the connecting groove 307, the side of the connecting seat 306 is provided with a positioning pin 308, the moving seat 305 and the connecting seat 306 are hingedly connected through the positioning pin 308, the connecting seat 306 is fixedly connected with a guide plate 309 on the side close to the center of the guide pipe 1, the guide plate 309 is in an arc structure, a plurality of guide plates 309 are distributed around the protective pipe body 2, the side of the guide plate 309 close to the center of the guide pipe 1 is in contact with and slidably connected with the protective pipe body 2, one end of the guide plate 309 is provided with an inclined surface 310 for facilitating the protective pipe body 2 to enter, when the protective pipe body 2 starts to be inserted into the guide pipe 1, it will first contact the inclined surface 310 at one end of the guide plate 309. Due to the arrangement of the inclined surface 310, the protective pipe body 2 can more smoothly push the guide plate 309 to move outward (i.e. away from the center of the guide pipe 1) along the inclined surface 310. The movement of the guide plate 309 will drive the connecting seat 306 connected thereto to move, and the connecting seat 306 will in turn drive the moving seat 305 to rotate around the hinge point of the connecting seat 306, and at the same time, the rotation of the moving seat 305 will also drive the rotating roller 303 to rotate in the fixed cylinder 302, and this rotating process will make the coil spring 304 be further stretched to store elastic potential energy.

[0028] With the continuous deepening of the protective pipe body 2 into the guide pipe 1, the protective pipe body 2 with different diameters will spread the guide plate 309 to different degrees. The larger the diameter of the protective pipe body 2, the farther the guide plate 309 will be spread outward, and correspondingly, the greater the rotation angle of the rotating roller 303, and the greater the stretching degree of the coil spring 304; and for the protective pipe body 2 with smaller diameter, the amplitude of the guide plate 309 being spread is small, the rotation angle of the rotating roller 303 is small, and the stretching degree of the coil spring 304 is also small. In this way, the plurality of guide plates 309 can adaptively adjust the position according to the actual diameter of the protective pipe body 2, and always closely fit the outer periphery of the protective pipe body 2, playing a good guiding role, ensuring that the protective pipe body 2 can smoothly pass along the predetermined direction in the guide pipe 1

[0029] When the protective pipe body 2 completely passes through the guide pipe 1, under the action of the elastic potential energy of the coil spring 304, the rotating roller 303 will rotate reversely, driving the moving seat 305, the connecting seat 306 and the guide plate 309 to return to the initial position, waiting for the next insertion of the protective pipe body 2.

[0030] The MPP power cable protection pipe with the adaptability to different diameters can be produced without frequently replacing the guide device for different pipe diameters, the production efficiency is greatly improved, the equipment replacement cost is reduced, and the pipe production process of various specifications can be flexibly applied.

[0031] The multiple circumferentially distributed guide plates 309 are in close contact and sliding connection with the protection pipe body 2, can stably and accurately guide the movement of the protection pipe body 2 in the guide pipe 1, ensure that the protection pipe body 2 travels along the correct direction, help to improve the stability and accuracy of pipe conveying in the production process, reduce the problems of pipe deviation, jam and the like, and further guarantee the product quality.
