Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically relating to a fiberglass jacking pipe with a guide structure. Background Technology

[0002] In various infrastructure construction projects, fiberglass reinforced plastic (FRP) pipe jacking plays a crucial role due to its unique advantages. Its strong corrosion resistance effectively resists the erosion of various chemicals in water, ensuring that water quality is not affected by the pipe material and guaranteeing the safety of urban residents' water supply. Compared to metal pipes, it significantly reduces the maintenance and replacement costs caused by pipe corrosion, extends the service life of water supply pipes, and makes the water supply system more stable and reliable.

[0003] In some existing FRP (fiberglass reinforced plastic) pipe jacking construction processes, there is often a defect that the ends are not easy to align. Difficulty in aligning the ends means that construction workers may need to spend more time and effort to adjust the position of the pipe to ensure that the ends can be aligned as much as possible. This may prolong the docking time of each pipe section, thereby slowing down the progress of the entire pipe jacking construction, delaying the construction period, and increasing construction costs.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-5 This is an embodiment of the present invention, which provides a fiberglass jacking pipe with a guide structure, comprising:

[0027] The jacking body 100 includes an outer pipe 101, a jacking inlet 102 fixedly connected to the outer end face of the outer pipe 101, and a connecting port 103 fixedly connected to the other end of the outer pipe 101 and used in conjunction with the jacking inlet 102.

[0028] It should be noted that the outer pipe 101 constitutes the main structure of the jacking pipe body 100 and is used to transport media such as urban water supply and drainage, gas, etc. The jacking inlet 102 is the propulsion port of the jacking pipe body 100 during construction, and is also used to connect with other jacking pipes at the connection port 103.

[0029] The positioning mechanism 200 includes a drive component 201 for storing rotational potential energy, and a clamping component 202 that uses the rotational potential energy of the drive component 201 to control the top inlet 102 to be accurately connected to the connection port 103.

[0030] Specifically, the drive assembly 201 includes a mounting plate 201a fixedly connected to the outer end face of the connection port 103, a knob 201b fixedly mounted to the inner wall of the mounting plate 201a via a bearing, and a spring 201c fixedly connected to the inner surface of the knob 201b.

[0031] Furthermore, the drive assembly 201 also includes a ratchet 201d fixedly sleeved on the outer surface of the spring 201c, a pawl 201e meshing with the outer surface of the ratchet 201d, a rotating column 201f and a compression spring 201g respectively fixedly installed on the inner walls of both sides of the mounting plate 201a and used in conjunction with the pawl 201e, a diagonal bar 201h fixedly connected to the surface of the pawl 201e away from the ratchet 201d, a limiting groove 201i opened on the outer surface of the mounting plate 201a and used in conjunction with the diagonal bar 201h, and a pressure block 201j fixedly installed on the outer surface of the top inlet 102 and used in conjunction with pushing the diagonal bar 201h.

[0032] Preferably, the outer end face of the spring 201c is fixedly connected to the inner wall of the mounting plate 201a, the pawl 201e is rotatably sleeved on the outer surface of the rotating column 201f, and the outer surface of the inclined rod 201h is in sliding contact with the inner wall of the limiting groove 201i.

[0033] It should be noted that the installation disk 201a is the installation medium for the driver component 201.

[0034] Rotating knob 201b winds the spring 201c to store rotational energy, simultaneously driving the threaded rod 202a to rotate. Spring 201c, when manually wound, stores rotational potential energy, providing power for the subsequent reverse rotation of the threaded rod 202a. Through the cooperation of ratchet 201d and pawl 201e, the spring can store energy even without external force, ensuring the stability of the stored rotational energy. Rotary pin 201f provides rotational support for pawl 201e. The spring 201g provides a restoring force for the pawl 201e, keeping it engaged with the ratchet 201d. When the top inlet 102 approaches the connection port 103, it can drive the pressure block 201j to squeeze the inclined rod 201h, causing the inclined rod 201h to drive the pawl 201e to rotate around the rotating column 201f as the center, and disengage it to the position where it is disengaged from the ratchet 201d, thereby releasing the rotational energy of the spring 201c and driving the threaded rod 202a to rotate in the opposite direction.

[0035] It should be noted that the clamping assembly 202 includes a threaded rod 202a fixedly connected to the through end of the knob 201b, an internal threaded block 202b threadedly connected to the outer surface of the threaded rod 202a, a connecting post 202c fixedly connected to the outer surface of the internal threaded block 202b, and a movable plate 202d fixedly installed at the other end of the connecting post 202c and used in conjunction with the top inlet 102.

[0036] Furthermore, the clamping assembly 202 also includes a fixing plate 202e fixedly connected to the surface of the connection port 103 away from the movable plate 202d, and a limiting rod 202f fixedly connected to the outer surface of the connection port 103 and used in conjunction with the connecting post 202c.

[0037] It should be noted that the threaded rod 202a rotates when the knob 201b is turned, driving the internal threaded block 202b to move axially through the threaded transmission. The internal threaded block 202b then converts the rotational motion of the threaded rod 202a into linear motion, driving the connecting column 202c and the movable plate 202d to move closer to the top inlet 102. The cooperation between the movable plate 202d and the fixed plate 202e helps to accurately connect it to the connection port 103. The limiting rod 202f is used to limit the movement direction of the connecting column 202c, thereby ensuring the stable movement of the movable plate 202d.

[0038] Specifically, a rotating bearing sleeve is installed at the connection between the knob 201b and the mounting plate 201a. The outer end face of the knob 201b is fixedly installed on the outer surface of the connection port 103 by the bearing. The outer surface of the connecting post 202c slides in contact with the inner wall of the limit rod 202f.

[0039] During use, before construction, manually rotate the knob 201b to drive the threaded rod 202a to rotate while simultaneously tightening the spring 201c, allowing the spring 201c to store rotational potential energy. During this process, the ratchet 201d rotates synchronously, squeezing the pawl 201e open. The pawl 201e quickly returns to its original position under the reaction force of the compression spring 201g, maintaining engagement with the ratchet 201d, ensuring that the energy stored in the spring 201c will not be released in the reverse direction.

[0040] When the pipe jacking construction begins: the pipe body with the top inlet 102 is pushed towards the pipe body with the connection port 103. As the two get closer, the pressure block 201j on the outer surface of the top inlet 102 gradually approaches the mounting plate 201a outside the connection port 103 and pushes the inclined rod 201h to slide in the limiting groove 201i. At the same time, it drives the pawl 201e to rotate around the rotating column 201f as the center, so that it rotates to the position where it is disengaged from the ratchet 201d.

[0041] At this time, the rotational potential energy stored in the spring 201c is released, causing the knob 201b and the threaded rod 202a to rotate in opposite directions. The threaded rod 202a drives the internal threaded block 202b to move axially, and the internal threaded block 202b drives the connecting column 202c to move laterally within the direction limited by the limit rod 202f. This causes the connecting column 202c to drive the movable plate 202d to move closer to the top inlet 102. Then, through the cooperation of the movable plate 202d and the fixed plate 202e, the top inlet 102 is accurately positioned, assisting the top inlet 102 to accurately connect to the connecting port 103 and complete the pipe docking.

[0042] In summary, by using the drive component 201 and the clamping component 202, the spring 201c can be wound up before construction to store rotational potential energy, and the rotational potential energy of the spring 201c can be released during construction to assist the top inlet 102 in accurately connecting to the connection port 103, thereby significantly reducing the docking time and accelerating the construction progress, so as to improve the quality of pipe connection while enhancing the stability and sealing of the pipe.
