[0003] In order to achieve lightweight and wear-resistant effects, existing lightweight wear-resistant mortar pipes cannot add steel wire during the production of pipes. Failure to add steel wire to the pipes will make the pipes soft, and the gray cement will hit the softer curved inner wall during conduction, which will cause damage to the pipes after long-term use. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the gray cement hits the softer inner wall of the bend during conduction, which may cause damage to the pipeline after long-term use.

[0006] Through the above technical solution, the double-layer copper wire interlayer between the outer tube wall and the inner tube wall improves the wear resistance, and the fixed wheel achieves the effect of being able to roll but not pull. The auxiliary support block and the fixed wheel are used to lift the tube at the bending point, which solves the problem that the single-layer tube body is not wear-resistant and there is bending at the connection after connection, which reduces the life of the tube body.

[0007] The utility model is further configured such that one end of the pushing arm away from the fixed wheel is fixedly connected to a connecting plate, a spring is sleeved on the outside of the pushing arm, one end of the spring is fixedly connected to one side of the support rod, and one end of the spring away from the support rod is fixedly connected to one side of the connecting plate.

[0008] The utility model is further configured such that the connecting plate is fixedly connected to a connecting block on one side away from the pushing arm, a swing rod is rotatably connected inside the connecting block, the swing rod is fixedly connected to a rotating block on one end away from the connecting block, and a pushing component is arranged outside the rotating block.

[0009] The utility model is further configured that the pushing assembly includes a rotating plate, the rotating plate is rotatably connected to the outside of the rotating block, and there are two groups of rotating plates symmetrically arranged on both sides of the fixing frame.

[0010] The utility model is further configured that one group of the rotating plates is fixedly connected to a fixed plate on one side away from the rotating block, the fixed plate is fixedly connected to a push rod on one side away from the rotating plate, and the push rod is fixedly connected to a lower rack on one end away from the fixed plate.

[0011] Through the above technical solution, it is achieved that the swing rod is pushed by the push rod, the connecting block pushes the connecting plate, and the connecting plate squeezes the spring, thereby driving the push arm and the fixed wheel to be fixed on the outer wall of the outer tube wall, thereby achieving a clamping effect, solving the problem of reduced life of the outer tube wall caused by wear at the fixing point due to the use of steel cable ties in the past, and improving the wear resistance and service life of the outer tube wall.

[0012] The utility model is further configured that a gear is meshed on one side of the lower rack, a support shaft is rotatably connected inside the gear, and one end of the support shaft away from the gear is rotatably connected inside the fixing frame.

[0015] The above technical solution realizes that the engagement knob is rotated to drive the gear, and the gear drives the upper rack and the lower rack to slide, so that the push rod slides on both sides of the fixing frame to push the fixing wheel to fix it, thereby solving the problem of inconvenient fixing by a single push and improving the convenience of fixing the inner tube wall.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model combines the outer tube wall and the double-layer copper wire interlayer with the inner tube wall when the outer tube wall is in use. At this time, the engagement knob is rotated to drive the gear to rotate. At this time, the upper rack and the lower rack will push the push rod to slide, so that the push rod pushes the swing rod to squeeze the connecting plate, and the connecting plate pushes the push arm to slide inside the support rod. At this time, the push arm will drive the fixed wheel to be squeezed on the surface of the outer tube wall. At this time, the outer tube wall is fixed, and the outer tube wall is supported for a second time by the auxiliary support block. This solves the problems of wear at the connection caused by the previous use of steel cable ties and the single outer tube wall being prone to leaks at the bending points, thereby improving the effect of fixing the outer tube wall and the wear resistance of the outer tube wall.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0027] See also Figure 1 - Figure 7 The lightweight wear-resistant mortar pipe comprises a fixing frame 1, an outer pipe wall 2 is arranged on one side of the fixing frame 1, a double-layer copper wire interlayer 3 is fixedly connected inside the outer pipe wall 2, an inner pipe wall 4 is fixedly connected inside the double-layer copper wire interlayer 3, a fixing wheel 5 is rotatably connected to the outside of the outer pipe wall 2, and a total of four groups of fixing wheels 5 are arranged in a circular array outside the outer pipe wall 2, a group of fixing wheels 5 away from the fixing frame 1 is rotatably connected to the opposite side with a pushing arm 6, and two groups of fixing wheels 5 close to the fixing frame 1 are rotatably connected to one side of the fixing frame 1 with an end support block 23, and the end support block 23 is fixedly connected to one side of the fixing frame 1 away from the side of the fixing wheel 5, and the outside of the pushing arm 6 is away from the fixing frame 1. A support rod 7 is slidably connected to one side of the wheel 5, and the support rod 7 is fixedly connected to one side of the fixing frame 1. A fixing rod 24 is threadedly connected to the outer side of the fixing frame 1. An auxiliary support block 25 is fixedly connected to the end of the fixing rod 24 away from the fixing frame 1. A fixed wheel 5 is arranged on the side of the auxiliary support block 25 close to the pushing arm 6. There are two groups of fixed wheels 5 that are symmetrically arranged. A connecting plate 9 is fixedly connected to the end of the pushing arm 6 away from the fixed wheel 5. A spring 8 is sleeved on the outside of the pushing arm 6. One end of the spring 8 is fixedly connected to one side of the support rod 7. The end of the spring 8 away from the support rod 7 is fixedly connected to one side of the connecting plate 9. The connecting plate 9 is fixedly connected to the side away from the pushing arm 6. The connecting block 10 has a swing rod 11 that is rotatably connected inside the connecting block 10. The swing rod 11 is fixedly connected to a rotating block 12 at one end away from the connecting block 10. A pushing assembly is arranged outside the rotating block 12. When working, the fixing frame 1 is first fixed to the discharge outlet of the cement tank truck, and then the outer pipe wall 2 is sleeved on the discharge outlet of the cement tank truck, and then the extended part is hung above the auxiliary support block 25. At this time, the swing rod 11 can be driven to be squeezed inward by the pushing assembly. At this time, the swing rod 11 pushes the connecting block 10 and the connecting plate 9, and the connecting block 10 and the connecting block 10 will squeeze the spring 8 when fixed, so that the pushing arm 6 slides along the inside of the support rod 7. When the outer tube wall 2 is in use, the fixing wheel 5 can be relied on to prevent the outer tube wall 2 from rotating, thereby allowing the outer tube wall 2 to adjust the impacted position. When the outer tube wall 2 is used, the pushing component is moved in the reverse direction. At this time, the rotating structure of the swing rod 11 can not achieve the stretching effect. When the driving force of the swing rod 11 is no longer applied to the spring 8, the connecting plate 9 is pushed, allowing the pushing arm 6 to slide inside the support rod 7, thereby allowing the fixing wheel 5 to move away from the surface of the outer tube wall 2, thereby achieving the effect of disassembling the outer tube wall 2.

[0028] The pushing assembly includes a rotating plate 13, which is rotatably connected to the outside of the rotating block 12. There are two groups of rotating plates 13 that are symmetrically arranged on both sides of the fixed frame 1, one of which is fixedly connected to a fixed plate 14 on the side away from the rotating block 12, and a pushing rod 15 is fixedly connected to the side of the fixed plate 14 away from the rotating plate 13. The end of the pushing rod 15 away from the fixed plate 14 is fixedly connected to a lower rack 20, and a gear 18 is meshed on one side of the lower rack 20. A support shaft 19 is rotatably connected inside the gear 18, and the support shaft 19 is rotatably connected to the inside of the fixed frame 1 at one end away from the gear 18. An upper rack 16 is meshed on the side of the support shaft 19 away from the lower rack 20, and the upper rack 16 is fixedly connected to one end of another group of pushing rods 15 away from the lower rack 20. One end of the pushing rod 15 away from the upper rack 16 is fixedly connected to one side of a group of rotating plates 13, and an upper rack 16 away from the rotating plate 13 is fixedly connected to an upper limit plate 17. The lower rack 20 is away from the rotating plate The lower rack 20 is fixedly connected to one end of the gear 13, and the engaging knob 22 is fixedly connected to the side of the gear 18 away from the support shaft 19. The engaging knob 22 is rotatably connected to the inside of the fixed frame 1. When working, when operating the pushing component, the engaging knob 22 can be rotated to allow the engaging knob 22 to drive the gear 18 to rotate outside the support shaft 19, so that the support shaft 19 pushes the upper rack 16 and the lower rack 20, and the lower rack 20 can limit the upper rack 16 and the lower rack 20 through the rotating plate 13 to prevent deviation when the support shaft 19 is pushed, and the engaging knob 22 can ensure that the pushing force of the spring 8 cannot push the lower rack 20 to reverse through a special structure when rotating. The rotating structure of the rotating plate 13 and the rotating block 12 ensures the thrust of the swing rod 11. When pushing the pushing rod 15, in order to prevent the upper rack 16 and the lower rack 20 from slipping, the sliding of the lower rack 20 of the upper rack 16 can be limited by the upper limiting plate 17 and the lower limiting plate 21.

[0029] When the utility model is in use, the fixing frame 1 is first fixed to the discharge outlet of the cement tank truck, and then the outer tube wall 2 is sleeved on the discharge outlet of the cement tank truck, and then the extended part is hung above the auxiliary support block 25. At this time, the swing rod 11 can be driven to be squeezed inward by the pushing component. At this time, the swing rod 11 pushes the connecting block 10 and the connecting plate 9, and the connecting block 10 and the connecting block 10 will squeeze the spring 8 when fixed, so that the pushing arm 6 slides along the inside of the support rod 7. At this time, the fixed wheel 5 will abut against the surface of the outer tube wall 2 to achieve extrusion and fixation. When in use, the gray cement in the tube impacts the inner wall of the inner tube wall 4. At this time, the fixing of the fixed wheel 5 can be relied on to prevent the outer tube wall 2 from rotating, so as to adjust the impacted position of the outer tube wall 2. After the outer tube wall 2 is used, the pushing component is moved in the opposite direction. At this time, the rotating structure of the swing rod 11 can not achieve the stretching effect, and when the driving force of the swing rod 11 is no longer given to the spring 8, it will push the connecting block 10 and the connecting plate 9. The connecting plate 9 allows the pushing arm 6 to slide inside the support rod 7 so that the fixed wheel 5 is away from the surface of the outer tube wall 2, thus achieving the effect of disassembling the outer tube wall 2. When operating the pushing component, the locking knob 22 can be rotated to allow the locking knob 22 to drive the gear 18 to rotate outside the support shaft 19, allowing the support shaft 19 to push the upper rack 16 and the lower rack 20, and the lower rack 20 can limit the upper rack 16 and the lower rack 20 through the rotating plate 13 to prevent deviation when the support shaft 19 is pushed, and the locking knob 22 can ensure that the pushing force of the spring 8 cannot push the lower rack 20 to slide in the opposite direction through a special structure when rotating, and the rotating structure of the rotating plate 13 and the rotating block 12 ensures the thrust of the swing rod 11. When pushing the pushing rod 15, in order to prevent the upper rack 16 and the lower rack 20 from slipping, the sliding of the lower rack 20 of the upper rack 16 can be limited by the upper limit plate 17 and the lower limit plate 21.
