For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Figure 1 The top view of the pipe conveying trolley provided by the embodiment of the present invention during actual use is shown. Figure 2 The figure shows a partial top view of the pipe conveying trolley provided by an embodiment of the present invention. Figure 3 The side view structure of the pipe conveying trolley provided by the embodiment of the present invention is shown. Figure 4 The diagram shows a top view of a partially enlarged structure of a positioning member in a pipe conveying trolley provided in an embodiment of the present invention.

[0037] Combination Figures 1 to 4It can be seen that the pipe conveying trolley provided by the present invention includes a supporting base plate 1 serving as the main body support of the trolley, and transverse telescopic support rods 3 are connected to both sides of the supporting base plate 1, and longitudinal telescopic stop rods 4 are connected to the end of each transverse telescopic support rod 3 away from the supporting base plate 1; wherein, a first locking piece is provided on each transverse telescopic support rod 3, and a second locking piece is provided on each longitudinal telescopic stop rod 4.

[0038] During actual use, the length of each transverse telescopic support rod and the length of each longitudinal telescopic baffle rod 4 can be adjusted according to the size and quantity of the pipes 7 to be transported; specifically, based on the size and quantity of the pipes 7 to be transported, each transverse telescopic support rod 3 is telescoped to a first preset length and locked by a first locking member, and each longitudinal telescopic baffle rod 4 is telescoped to a second preset length and locked by a second locking member. At this time, a loading space for accommodating pipes is formed by the support base plate 1, each transverse telescopic support rod 3 and each longitudinal telescopic baffle rod 4. The loading space is used to prevent the pipes 7 to be transported, and the size of the loading space is adjustable (by adjusting the transverse telescopic support rod 3 and the longitudinal telescopic baffle rod 4). The pipes 7 to be transported are accommodated and arranged in the loading space formed between the support base plate 1, each transverse telescopic support rod 3 and each longitudinal telescopic baffle rod 4.

[0039] It should be noted that the loading space of the pipe conveying trolley provided by the present invention can be adjusted by adjusting the transverse telescopic support rod 3 and the longitudinal telescopic blocking rod 4, wherein adjusting the transverse telescopic support rod 3 can adjust the width of the loading space, and adjusting the longitudinal telescopic blocking rod 4 can adjust the height of the loading space; in actual use, the loading space of the pipe conveying trolley can be adjusted according to the size and quantity of the pipes 7 to be transported, and the size of the loading space can be kept at the required minimum value, thereby reducing the space occupied by the entire pipe conveying trolley, facilitating the movement of the pipe conveying trolley, and improving the transportation efficiency of the plates. In addition, the transverse telescopic support rods 3 and the longitudinal telescopic blocking rods 4 provided by the present invention can form a fence structure. In actual use, the pipes 7 to be transported are squeezed against each other and stuck in the fence structure, which can effectively improve the support stability of the pipes 7 to be transported, avoid rolling of the pipes 7 to be transported, and prevent damage to the pipes 7 to be transported.

[0040] In order to achieve length adjustment of the transverse telescopic support rod 3, the transverse telescopic support rod 3 may include a first transverse support tube 31 connected to the support base plate 1, and a second transverse support tube 32 is movably inserted at one end of the first transverse support tube 31 away from the support base plate 1; wherein each longitudinal telescopic stop rod 4 is connected to the end of the corresponding second transverse support tube 32.

[0041] In addition, in order to achieve locking between the first transverse support tube 31 and the second transverse support tube 32, the positioning hole 33 can be used in conjunction with the locking screw for locking. For example, a first positioning hole can be opened on the first transverse support tube 31, and a second positioning hole can be opened on the second transverse support tube 32; wherein, after the second transverse support tube 32 is adjusted to the first preset position in the first transverse support tube 31, it is fixed to the first transverse support tube 31 by the first locking screw in conjunction with the first positioning hole and the second positioning hole.

[0042] In addition, in order to realize the connection between the first transverse support tube 31 and the support base plate 1, a guide positioning long groove 8 can be horizontally arranged on the support base plate 1, and one end of the first transverse support tube 31 is slidably connected in the guide positioning long groove 8; and, a third positioning hole is opened on the guide positioning long groove 8. After the first transverse support tube 31 is adjusted to the second preset position in the guide positioning long groove 8, it is fixed to the guide positioning long groove 8 by the second locking screw in conjunction with the first positioning hole and the third positioning hole.

[0043] In a specific embodiment of the present invention, in order to realize the connection between the longitudinal telescopic baffle rod 4 and the transverse telescopic support rod 3, a positioning member 10 can be provided at the end of each second transverse support tube 32, and each longitudinal telescopic baffle rod 4 is connected to the end of the corresponding second transverse support tube 32 through the positioning member 10; wherein the positioning member 10 includes a slot 101 fixed at the end of the second transverse support tube 32, and the bottom of the longitudinal telescopic baffle rod 4 is limited in the slot 101 and fixed by a locking bolt 102.

[0044] Furthermore, in order to realize the telescopic adjustment of the longitudinal telescopic baffle rod 4, the longitudinal telescopic baffle rod 4 may include a first longitudinal baffle tube 42 connected to the second transverse support tube 32 through a positioning piece 10, and a second longitudinal baffle tube 41 is movably inserted at the upper end of the first longitudinal baffle tube 42; and, a fourth positioning hole is opened on the first longitudinal baffle tube 42, and a fifth positioning hole is opened on the second longitudinal baffle tube 41; wherein, after the second longitudinal baffle tube 41 is adjusted to the third preset position in the first longitudinal baffle tube 42, it is fixed to the first longitudinal baffle tube 42 by a third locking screw in conjunction with the fourth positioning hole and the fifth positioning hole.

[0045] It should be noted that there are multiple (at least two) transverse telescopic support rods 3 connected to both sides of the support base plate 1 ; and the transverse telescopic support rods 3 are evenly distributed on both sides of the support base plate 1 .

[0046] In addition, in order to improve the supporting stability of the entire support plate, the supporting base plate 1 may include a supporting frame 9 and a supporting plate fixed on the supporting frame 9; and, in order to realize the rolling operation of the entire pipe conveying trolley, supporting rear axles 11 may be provided on both sides of the bottom of the supporting base plate 1, and rollers 2 are rotatably connected to each supporting rear axle 11.

[0047] In addition, in order to provide power to the pipe conveying trolley, a connecting rod 5 may be connected to the front end of the supporting base plate 1 , and the supporting base plate 1 is connected to an external traction device 6 via the connecting rod 5 .

[0048] In the actual manufacturing process, in order to ensure the overall rigidity of the entire pipe conveying trolley, the supporting bottom plate 1 of the conveying trolley is made by cutting and welding channel steel. The outer contour size of the supporting bottom plate 1 is 4000*2500mm. It can also be made according to different on-site requirements. The outer contour is a rectangular square channel steel frame, with a channel steel longitudinal beam and three channel steel cross beams in the middle, thereby forming a supporting frame 9. A 3mm thick patterned plate is laid on the supporting frame 9 as a supporting plate, thereby forming the entire supporting bottom plate 1.

[0049] Three channel steel slots 101 are provided on the transverse front side of the supporting base plate 1 as guiding and positioning long slots 8 for controlling the initial length of the transverse telescopic support rod 3. The transverse telescopic support rod 3 is an antenna-type telescopic arm structure (the telescopic arm can be telescoped according to the actual transportation demand to expand the transverse transportation space). The antenna-type telescopic arm structure is made of square steel pipes. The inner square pipe (i.e., the first transverse support pipe 31) is slightly larger than the square pipe inserted on the outside (i.e., the second transverse support pipe 32), so that the insertion forms a telescopic fit. The center areas of the two square pipes are both opened with holes (i.e., positioning holes), which are fixed by locking screws and can be adjusted as needed.

[0050] In addition, in order to ensure that the end of the antenna-type telescopic arm structure restricts and blocks the pipe, the longitudinal telescopic barrier rod 4 adopts a method of two steel tubes (i.e., the first longitudinal barrier tube 42 and the second longitudinal barrier tube 41) with a central opening (i.e., a positioning hole), which also simulates the antenna sleeve-type upward and downward telescopic height adjustment, and relies on locking screws for fixing and movable adjustment.

[0051] In addition, in order to ensure the flexibility and maneuverability of the entire pipe conveying trolley, the pipe conveying trolley adopts a single-axis tire-type rear axle for support, and relies on the traction device 6 such as an electric car and tractor at the front end to pull it to move within the factory; and in order to ensure the stability of transportation and the convenience of loading and unloading, the vehicle body height is controlled at about 500mm.

[0052] It can be seen from the above specific embodiments that the pipe conveying trolley provided by the present invention has at least the following advantages:

[0053] 1. The vehicle adopts an adjustable, assembled and fitted frame platform body structure. The vehicle body has overall rigidity and can achieve the functionality of safe and effective transportation and construction.

[0054] 2. By controlling the length of the horizontal telescopic support rod and the longitudinal telescopic barrier rod, the transportation space can be flexibly expanded to achieve higher transportation efficiency;

[0055] 3. The pipe conveying trolley provided by the present invention has a simple structure, is quick to use, safe and reliable, and can ensure structural integrity, effectiveness, convenience, and maneuverability; moreover, the entire trolley is green and environmentally friendly, can be adapted to similar scenarios, and ensures quality safety and functionality.

However, those skilled in the art should understand that various improvements can be made to the pipe conveying trolley proposed by the present invention without departing from the content of the present invention. Therefore, the protection scope of the present invention should be determined by the content of the attached claims.
