[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one 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 is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0029] Reference Figures 1-4 The first embodiment of the present invention provides a pipe transportation device, which includes a base unit 100 and a pipe laying unit 200.

[0030] The basic unit 100 includes a vehicle body 101, a wheel 102 disposed at one end of the vehicle body 101, a storage cavity 103 formed on the outer surface of the vehicle body 101 for storing the tube G, a connecting wheel 104 disposed in the storage cavity 103 for reducing friction, and a guide mechanism 105 connected to the outside of the vehicle body 101 and communicating with the bottom end of the storage cavity 103.

[0031] The small-diameter tube G can be stored in the storage cavity 103 so that the vehicle body 101 can be moved to the required position by the wheel 102 and then discharged through the guide mechanism 105. During the discharge process, the connecting wheel 104 reduces friction and guides the tube G, effectively preventing it from getting stuck in the storage cavity 103.

[0032] During use, the pipe unit 200 is located at one end of the vehicle body 101. It includes a pedal mechanism 201 located on the outside of the vehicle body 101 and extending to its bottom end, a transmission gear 202 limited within the vehicle body 101, a drive mechanism 203 connected to the transmission gear 202 and passing through one end of the pedal mechanism 201, and a pipe pushing mechanism 204 located within the vehicle body 101 and cooperating with the drive mechanism 203 and the pipe body G.

[0033] After being transported to the desired location, the pedal mechanism 201 can be stepped on, causing the pedal mechanism 201 to continuously drive the drive mechanism 203 to reciprocate through the transmission gear 202. At this time, the drive mechanism 203 will cooperate with the tube pusher mechanism 204 to drive the tube pusher mechanism 204 to rotate in only one direction, and the tube body G will be discharged from the storage chamber 103 by the friction of rotation.

[0034] The guiding mechanism 105 includes a conduit ring 105a that extends from one end of the vehicle body 101 and a telescopic tube 105b disposed at one end of the conduit ring 105a and fixed inside the vehicle body 101. Before discharge, the tube body G discharged from the storage cavity 103 can be discharged from the conduit ring 105a to the designated position through the telescopic tube 105b by pulling the conduit ring 105a and stretching the telescopic tube 105b. Example 2

[0035] Reference Figures 1-7 This is the second embodiment of the present invention, which differs from the first embodiment in that the specific implementation of the pipe arrangement unit 200 is as follows.

[0036] Compared to Embodiment 1, the pedal mechanism 201 further includes a pedal 201a, a connecting plate 201b fixed to one end of the pedal 201a and extending to the vehicle body 101, and the connecting plate 201b is disposed in the vehicle body 101 by a tension spring. The drive mechanism 203 includes a guide plate 203a that is limited to slide within the vehicle body 101, an inner groove 203b formed on the outer surface of the guide plate 203a and penetrated by the connecting plate 201b, and a twisted rod 203c disposed at one end of the guide plate 203a and cooperating with the push tube mechanism 204.

[0037] Furthermore, both the guide plate 203a and the connecting plate 201b mesh with the transmission gear 202, and both the connecting plate 201b can slide in the vehicle body 101 and the inner groove 203b. The push tube mechanism 204 includes a connecting component 204a that cooperates with the twisted rod 203c, and a push tube component 204b that is sleeved on the connecting component 204a and rotates unidirectionally with it.

[0038] When the pedal 201a is pressed, the pedal 201a pulls the connecting plate 201b downward to charge the tension spring. When released, the connecting plate 201b is reset by the charged tension spring, causing the connecting plate 201b to slide back and forth and mesh with the transmission gear 202. This allows the transmission gear 202 to mesh with the guide plate 203a, enabling the guide plate 203a to slide back and forth. At the same time, the inner groove 203b prevents the connecting plate 201b and the guide plate 203a from jamming together. The connecting plate 201b drives the spiral rod 203c to slide back and forth and cooperate with the connecting assembly 204a, causing the push tube assembly 204b to rotate unidirectionally and push out the tube body G.

[0039] The connecting component 204a includes a connecting disc 204a-1 through which the twist rod 203c passes, a protrusion 204a-2 disposed on the outer side of the connecting disc 204a-1, and a connecting block 204a-3 disposed on the inner surface of the connecting disc 204a-1 and engaged with the twist rod 203c.

[0040] During use, the push tube assembly 204b includes a push plate 204b-1 fitted around the outer end of the connecting plate 204a-1, a top block 204b-2 rotatable on the inner surface of the push plate 204b-1, a spring 204b-3 connected to the outer surface of the top block 204b-2 and fixed to the inner surface of the push plate 204b-1, and a stop block 204b-4 on the inner surface of the push plate 204b-1 to prevent the top block 204b-2 from rotating to one side. The push plate 204b-1 can rotate outside the connecting plate 204a-1 and inside the vehicle body 101 and fit against the tube body G, and the top block 204b-2 fits against the protrusion 204a-2.

[0041] When the twist rod 203c slides back and forth, it will press the connecting block 204a-3 back and forth, causing the connecting block 204a-3 to follow the spiral surface of the twist rod 203c and drive the connecting plate 204a-1 to rotate back and forth. When the connecting plate 204a-1 rotates, it will drive the protrusion 204a-2 to rotate.

[0042] When the protrusion 204a-2 rotates in the forward direction, it will compress the top block 204b-2, which is blocked by the stop block 204b-4. This causes the top block 204b-2 to push the stop block 204b-4, thereby rotating the fixedly connected push plate 204b-1. This push plate 204b-1 then pushes the tube body G out of the storage cavity 103. When the protrusion 204a-2 rotates in the reverse direction, under the pressure of the tube body G on the push plate 204b-1, the protrusion 204a-2... Pushing the top block 204b-2, the top block 204b-2 is not blocked at this time, but is pushed to rotate, allowing the top block 204b-2 to charge the spring 204b-3. Subsequently, the charged spring 204b-3 is rotated to reset, so that when the protrusion 204a-2 rotates in the forward direction, it can drive the push plate 204b-1 to rotate, but when it rotates in the reverse direction, it cannot drive the push plate 204b-1 to rotate, so that the push plate 204b-1 can only rotate in one direction to squeeze and push the tube body G.

[0043] The remaining structure is the same as that in Example 1. Example 3

[0044] Reference Figure 1 and Figure 3 This is the third embodiment of the present invention, which differs from the second embodiment in that it further includes a tube clamping unit 300 disposed at both ends of the vehicle body 101.

[0045] The system includes a rotatable base plate 301 disposed on both sides of the vehicle body 101, a blocking mechanism 302 connected to the outer surface of the base plate 301 for blocking large-diameter pipes, and a locking mechanism 303 for locking the base plate 301. The base plate 301 includes a base member 301a connected to both sides of the vehicle body 101 by a shaft and a clamping plate 301b disposed on one side of the base member 301a.

[0046] Compared to Embodiment 2, the blocking mechanism 302 further includes an inclined block 302a disposed on the outer surface of the base component 301a, a base 302b fixed to the outer surface of the base component 301a, and a barrier 302c connected to the base 302b and limited in rotation by the inclined block 302a; the locking mechanism 303 includes a fixing block 303a fixed to one end of the vehicle body 101, a return spring 303b disposed on the outer surface of the fixing block 303a, and a pull rod 303c disposed at one end of the return spring 303b and passing through the fixing block 303a and the locking plate 301b respectively.

[0047] When transporting a large-diameter pipe G, the clamping plate 301b, normally held in place by the pull rod 303c, will not lower the base plate 301. Only when the pull rod 303c is pulled by the return spring 303b will it disengage from the clamping plate 301b and slide in the fixed block 303a, allowing the base component 301a to rotate. Subsequently, the barrier 302c on the base 302b is rotated and pulled open to abut against the inclined block 302a. The inclined block 302a then holds the barrier 302c in place to prevent it from rotating again. This allows the barrier 302c to hold the large-diameter pipe G in place, preventing the pipe from rolling and falling during transport.

[0048] When not in use, the base plate 301 is flipped over so that the pull rod 303c locks the plate 301b again under the action of the return spring 303b.

[0049] The remaining structure is the same as that in Example 2.
