Description

Technical Field

[0001] The invention relates to the field of municipal road and bridge pipe network laying, in particular to a pipe fixing device for municipal road and bridge pipe network laying. Background Art

[0002] The laying of municipal road and bridge pipelines is a crucial component of urban infrastructure development, encompassing the comprehensive layout and construction of various pipelines, including water supply, drainage, gas, electricity, and communications. Through scientific planning and high-standard construction, the pipeline system is ensured to be safe, reliable, and efficient, while also taking into account the load-bearing capacity and durability of roads and bridges. Construction utilizes techniques such as excavation and laying, pipe jacking, and shield tunneling, with emphasis on coordination with transportation, landscaping, and other projects to minimize impacts on public life. Upon completion, the project will not only meet the city's operational needs, but also enhance flood control and drainage capabilities, optimize underground space utilization, and provide a solid foundation for sustainable urban development.

The top of the pipe fixing base is movably connected to the first connecting seat through a movable bearing, and the bottom of the pipe fixing base is movably connected to the second connecting seat through a movable bearing. One side of the pipe fixing base is movably connected to the first locking mechanism, and the other side of the pipe fixing base is movably connected to the second locking mechanism. The present invention comes with a first connecting seat and a second connecting seat, and multiple pipe fixing devices can be combined and spliced ​​for use. They can be placed horizontally for fixing pipes on horizontal pipe networks, or placed vertically for fixing pipes on vertical pipe networks.

The rotating rod 17 is designed as a circular rod; Furthermore, the front end of the rotating clamping plate 13 is fixedly connected to the rear end of the supporting movable rod 16 near the inner side of the outer body 1 of the device. The front end of the supporting movable rod 16 abuts against the rear end of the first transmission circular disk 15, and the supporting movable rod 16 is slidably connected to the first transmission circular disk 15. Furthermore, the inner side of the rotating splint 13 is fixedly connected to the anti-skid protection block 21, and the anti-skid protection block 21 is designed with rubber material. The anti-skid protection block 21 is clamped on the outer side of the road bridge pipe network body 2, and the anti-skid protection block 21 is provided with multiple sets of anti-skid grooves; Furthermore, the outer side of the supporting fixed connection block 20 on the right side near the upper position at the rear end of the first transmission circular disk 15 is fixedly connected to one end of the swing control rod 22. A locking socket 23 is provided at the front end of the swing control rod 22. The locking socket 23 is circular in design. The rear end of the locking movable plug rod 24 is inserted into the locking socket 23. The locking movable plug rod 24 is a circular rod design, and the locking socket 23 is slidably connected to the locking movable plug rod 24. The outer body 1 of the device is sleeved on the outer side of the locking movable plug rod 24, and the outer body 1 of the device is slidably connected to the locking movable plug rod 24. The inner wall of the outer body 1 of the device sleeved on the outer side of the locking movable plug rod 24 is circular in design. Furthermore, the front end of the locking movable rod 24 is fixedly connected to the middle position of the rear end of the movable connecting plate 25, and a return spring 26 is sleeved on the outer side of the locking movable rod 24. The rear end of the return spring 26 is fixedly connected to the front end of the outer body 1 of the device, and the front end of the return spring 26 is fixedly connected to the rear end of the movable connecting plate 25; Furthermore, guide fixing rods 27 are also sleeved on both sides of the movable connecting plate 25, and the movable connecting plate 25 is slidably connected to the guide fixing rods 27. The guide fixing rods 27 are designed as circular rods. The inner wall of the movable connecting plate 25 sleeved on the outer side of the guide fixing rods 27 is designed as a circular rod. The rear end of the guide fixing rods 27 is fixedly connected to the front end of the outer body 1 of the device. The front end of the guide fixing rods 27 is fixedly connected to the rear end of the limit fixing plate 28. The limit fixing plate 28 is designed as a circular rod. During operation, the road bridge pipe network body 2 is first inserted into the outer body 1 of the device, the first transmission circular disc 15 and the second transmission circular disc 18. After the road bridge pipe network body 2 is inserted into the outer body 1 of the device, the first transmission circular disc 15 and the second transmission circular disc 18, the swing control rod 22 is swung downward to drive the swing control rod 22 to rotate downward. When the swing control rod 22 rotates downward, it drives the supporting fixed connection block 20 to move synchronously, and when the supporting fixed connection block 20 moves, the second transmission circular disc 18 and the first transmission circular disc 15 are rotated at the same time, and when the second transmission circular disc 18 and the first transmission circular disc 15 rotate, the outer side of the first transmission circular disc 15 will rotate against the inner wall of the fixed guide block 10 , and the fixed stopper 14 fixed below the fixed guide block 10 will block and limit the position of the first transmission circular disk 15 to prevent the first transmission circular disk 15 from falling off and ensure the stability of the first transmission circular disk 15 during the rotation. At the same time, during the rotation of the second transmission circular disk 18, since the rotating rod 17 is inserted into the circular rotation groove 19 opened on the surface of the second transmission circular disk 18, the second transmission circular disk 18 drives the rotating rod 17 to move at the same time, and the rotating rod 17 will rotate along the circular rotation groove 19 during the movement. At the same time, when the rotating rod 17 rotates, it drives the rotating splint 13 to rotate synchronously, and when the rotating splint 13 rotates, it drives the moving slide rod 12 to rotate synchronously, and the moving slide rod 12 rotates along The guide sliding groove 11 provided in the fixed guide block 10 rotates, and the moving slide bar 12 moves outward along the inside of the guide sliding groove 11 until the moving slide bar 12 and the inside of the guide sliding groove 11 are close to the outside. When the rotating splint 13 rotates, the supporting moving rod 16 is driven to rotate in contact with the surface of the first transmission circular disk 15, and the first transmission circular disk 15 also supports the position of the rotating splint 13 to ensure that the positions of the moving slide bar 12 and the rotating rod 17 will not deviate or fall off. When the rotating splint 13 rotates, it will slowly tighten until it drives the anti-skid protection block 21 to clamp the outside of the road bridge pipe network main body 2. Since there are multiple sets of anti-skid grooves on the outside of the anti-skid protection block 21, it can effectively prevent skidding. The anti-skid protection block 21 is made of rubber material, which is a soft material. Therefore, when the clamping force of the rotating clamping plate 13 is too large, the outer side of the road bridge pipe network main body 2 can be protected to prevent the outer side of the road bridge pipe network main body 2 from being damaged or deformed due to the excessive force applied by the rotating clamping plate 13. The swing control rod 22 will be released from the locking movable plug rod 24 during the rotation process. Since the swing control rod 22 is a round rod design and the rear end of the locking movable plug rod 24 is an arc-shaped design, when the swing control rod 22 moves to the rear end position of the locking movable plug rod 24, it will squeeze the locking movable plug rod 24 to retract forward. When the locking movable plug rod 24 retracts forward, it will move forward along the inside of the outer body 1 of the device.At the same time, the movable connecting plate 25 moves forward, which will pull the return spring 26 on the outer side of the locking movable plug rod 24 to extend until the locking hole 23 provided by the swing control rod 22 moves to the rear end position of the locking movable plug rod 24. Under the rebound force of the return spring 26, the movable connecting plate 25 is driven to move backward, and at the same time, it moves along the outer side of the guide fixing rod 27 and drives the locking movable plug rod 24 to move backward until the rear end of the locking movable plug rod 24 is inserted into the locking hole 23 for fixed locking. When dismantling, first pull the movable connecting plate 25 forward. When the movable connecting plate 25 is pulled forward, the movable connecting plate 25 will move forward along the outer side of the guide fixing rod 27, and at the same time pull the return spring 26 to extend. In the process of the movable connecting plate 25 moving forward, it will drive the locking movable plug rod 24 to move forward along the inner side of the locking hole 23 provided by the outer body 1 of the device and the swing control rod 22. After the locking movable plug rod 24 is disengaged from the inner side of the locking hole 23, the swing control rod 22 can be rotated upward, and then the movable connecting plate 25 is released. The locking movable plug rod 24 will rebound to its original position by the return spring 26, and when the swing control rod 22 is rotated upward, it will drive the rotating clamping plate 13 to rotate. When the rotating clamping plate 13 rotates, it is opposite to the direction of rotation during the locking process. Therefore, when the rotating clamping plate 13 rotates in the opposite direction, it will slowly separate from the outer side of the road bridge pipe network body 2 until the dismantling is completed.

[0021] Example 2 See also Figures 1-4 As shown, Comparative Example 1 is another embodiment of the present invention. The bottom end of the outer body 1 of the device is fixedly connected to the top end of the fixed connection seat 29, and the bottom end of the fixed connection seat 29 is fixedly connected to the top end of the fixed mounting seat 30. The fixed mounting seat 30 is also provided with a knob bolt 31 near the corner position, and the knob bolt 31 is threadedly connected to the fixed mounting seat 30. The fixed mounting seat 30 is square in design. Furthermore, the bottom end of the knob bolt 31 is fixedly connected to the top end of the earth-breaking drill bit 32, and the earth-breaking drill bit 32 is of a conical design; During operation, when the device is fixed in position, the outer body 1 of the device is first placed at the position where the road bridge pipe network body 2 needs to be laid, so that the fixed mounting seat 30 at the bottom end of the fixed connecting seat 29 contacts the ground, and then the knob bolt 31 is turned along the inside of the fixed mounting seat 30, driving the knob bolt 31 to move downward along the inside of the fixed mounting seat 30. Since a soil-breaking drill bit 32 is fixed to the bottom end of the knob bolt 31, and the soil-breaking drill bit 32 is conical in design, the soil layer will be easily cut during the downward movement of the soil-breaking drill bit 32 until the fixed mounting seat 30 is firmly fixed to the ground. When it needs to be removed, it is only necessary to reverse the knob bolt 31 to drive the knob bolt 31 to move upward along the inside of the fixed mounting seat 30, and at the same time drive the soil-breaking drill bit 32 to move upward until the knob bolt 31 is completely disengaged.
