[0002] A pipe jacking machine is a mechanical device used for underground pipeline laying, and is widely used in projects such as underground pipelines, communication cables, water supply, drainage, and natural gas pipelines in urban infrastructure construction. Its main function is to lay pipelines horizontally or nearly horizontally underground, and the construction process does not require excavation of the ground, reducing the impact on ground traffic, the environment, and surrounding facilities.

[0003] The working principle of the pipe jacking machine mainly lies in pushing the pipe segments into the soil layer one by one along the axial direction through hydraulic pressure, pneumatic pressure, mechanical pushing, etc., so as to gradually form a pipeline environment with the required length in the soil layer.

[0004] The existing pipe jacking machines generally have the following problems during use: (1) Since the pipe jacking operation is a continuous operation and it is necessary to continuously supply the pipe segments provided in sections to the pipe jacking machine, the pipe supply speed and accuracy will directly determine the pipe jacking efficiency, and the existing pipe jacking machines generally cannot stably and continuously supply the pipes; (2) Since the pipe jacking machine can only jack one pipe at a time, if the pipes are continuously supplied, it is very likely that the pipes will accumulate at the inlet of the pipe jacking machine, even affecting the jacking operation of the pipe jacking machine.

Detailed implementation manners

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with embodiments and drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and shall not be construed as a limitation to the present invention.

[0027] Please refer to Figures 1 to 7, an embodiment of the present invention provides a continuous pipe jacking mechanism, including: a pair of conveyor belts 10, both of the two conveyor belts 10 are supported by an input roller 11 and an output roller 12, so that the two conveyor belts 10 are symmetrically and spaced apart, and the installation height of the output roller 12 is higher than that of the input roller 11, so that the conveyor belt 10 is divided into a climbing section and a gentle falling section, the climbing section is used for loading pipes, and the gentle falling section is used for unloading pipes; secondly, it includes two groups of bearing plates 20, the two groups of bearing plates 20 respectively correspond to the two conveyor belts 10 one by one, each group of bearing plates 20 is evenly and spaced on the corresponding conveyor belt 10, the two groups of bearing plates 20 are symmetrically arranged, and the bearing plates 20 are used for bearing pipes. The bearing plate 20 at the bottom of the climbing section is connected to the pipe source to obtain the pipes of the pipe source; thirdly, it includes a conversion platform 30, the installation height of the top surface of the conversion platform 30 is higher than that of the top surface of the conveyor belt 10, one side of the top surface of the conversion platform 30 facing the climbing section is the starting side 31, and the side facing the gentle falling section is the ending side 32. The bearing plate 20 located in the climbing section can lift the pipe to the starting side 31, move the pipe from the starting side 31 to the ending side 32, and fall to the bearing plate 20 located in the gentle falling section; fourthly, it includes a pipe unloading plate 40, the pipe unloading plate 40 is inclined, the high side of the pipe unloading plate 40 is fixedly arranged on the gentle falling section, and a pipe jacking machine 60 is arranged on the low side of the pipe unloading plate 40. When the pipe on the bearing plate 20 located in the gentle falling section falls to contact the top surface of the pipe unloading plate 40, the pipe detaches from the bearing plate 20 and rolls from the high side to the low side of the pipe unloading plate 40, and the pipe jacking machine 60 can axially press the pipe located on the low side of the pipe unloading plate 40.

[0028] The continuous pipe jacking mechanism provided by the present application is provided with a conveyor belt 10, and the conveyor belt 10 is supported by an input roller 11 and an output roller 12, and the input roller 11 is provided at a height lower than the setting height of the output roller 12, so that the conveyor belt 10 is divided into a climbing section and a slow-down section, and the carrying plates 20 are evenly spaced on the conveyor belt 10, so that the carrying plates 20 move synchronously with the conveyor belt 10, so that the carrying plates 20 can rise from the bottom of the climbing section to the top of the climbing section, and then turn over, and descend from the top of the slow-down section to the bottom of the slow-down section, and then turn over again and repeat the above movement, so as to use the carrying plates 20 to obtain and lift the pipe in the climbing section, and use the carrying plates 20 to lift the pipe in the slow-down section. The pipes are unloaded and transferred to the pipe jacking machine 60; a pair of conveyor belts 10 and two sets of carrying plates 20 are set, and the two sets of carrying plates 20 are set on the two conveyor belts 10 to form a symmetrical structure on the two conveyor belts 10. The carrying plates 20 on the two conveyor belts 10 act on the two ends of the pipe in pairs to improve the stability of the pipe during the rising and falling process; since the carrying plates 20 will gradually turn over at the junction of the climbing section and the slow-fall section, the pipes carried on them will inevitably slide from the current top surface of the carrying plates 20, resulting in failure to supply pipes. By setting a conversion platform 30, the setting height of the top surface of the conversion platform 30 is limited, and it is used to work in conjunction with the carrying plates 20, When the carrying plate 20 carries the pipe and gradually climbs along the climbing section until the bottom surface of the pipe is flush with the top surface of the conversion platform 30, the pipe naturally falls on the top surface of the conversion platform 30, and then the carrying plate 20 will make a circular motion around the axis of the output roller 12, thereby continuously pushing the pipe to roll from the starting side 31 of the conversion platform 30 to the end side 32, and then fall along the end side 32 and fall on the pair of carrying plates 20 located at the top of the slow-down section, and then fall along the slow-down section with the pair of carrying plates 20, thereby realizing a smooth conversion of the pipe between the climbing section and the slow-down section; on this basis, by setting the unloading plate 40, setting it to be inclined, and the high side is fixedly set in the slow-down section, using it to receive the pipe The pipes that fall together with the carrier plate 20 are received, and then the pipes roll from the high side to the low side along with their inclined top surface, thereby entering the pipe jacking machine 60 located on the low side of the pipe unloading plate 40, and then the pipe jacking machine 60 can be used to push the pipes axially into the soil layer; by controlling the transmission speed of the conveyor belt 10 and correspondingly setting the distance between two adjacent carrier plates 20, the speed of pipe supply can be effectively controlled, thereby avoiding the accumulation of pipes at the entrance of the pipe jacking machine 60; through the mutual cooperation of the above-mentioned features, the continuous pipe jacking mechanism can effectively solve the problem that the existing pipe jacking machine cannot supply pipes stably and continuously, and is prone to cause pipe accumulation at the entrance of the pipe jacking machine, affecting the normal pipe jacking operation.

[0029] Specifically, the above-mentioned conveyor belt 10 and the input roller 11 and the output roller 12 are driven by gears. The middle part of the conveyor belt 10 is hollowed out, and shift rods are installed at equal intervals. The input roller 11 and the output roller 12 are coaxially equipped with gears, and the gears are engaged with the shift rods, thereby driving the conveyor belt 10 to be transported by shifting the shift rods.

[0030] It should be noted that the input roller 11 or the output roller 12 is connected to a drive motor.

[0031] It should be noted that the tube unloading plate 40 is sandwiched between the two conveyor belts 10 .

[0032] In order to prevent unnecessary sliding and rolling of the pipe when the top surface of the load-bearing plate 20 rises or falls, the load-bearing plate 20 is tilted so that the top surface height of the load-bearing plate 20 located in the climbing section gradually decreases in the direction approaching the conveyor belt 10, and the top surface height of the load-bearing plate 20 located in the slow-fall section gradually increases in the direction approaching the conveyor belt 10; a limit plate 21 is provided on the side of the load-bearing plate 20 away from the conveyor belt 10, and when the load-bearing plate 20 is located in the slow-fall section, the limit plate 21 is vertically arranged upward to form a V-shaped pipe unloading groove between the limit plate 21 and the load-bearing plate 20; the high side of the pipe unloading plate 40 is located below the side of the pipe unloading groove.

[0033] In order to prevent the pipe from directly contacting the conveyor belt 10 during the rising process, thereby exerting pressure on the conveyor belt 10, the starting side 31 extends along the length direction of the climbing section to form a climbing wall 33. The distance between the climbing wall 33 and the axis of the output roller 12 is slightly larger than the distance between the climbing section and the axis of the output roller 12, so as to form a V-shaped upper pipe groove between the climbing wall 33 and the supporting plate 20.

[0034] Through the above arrangement, the pipe directly contacts the climbing wall 33 during the rising process, thereby forming a gap between the pipe and the conveyor belt 10 to avoid direct contact, and the top of the climbing wall 33 is connected to the starting side 31, so that the pipe can rise more smoothly along the climbing wall 33 to the starting side 31, and then fall on the top surface of the conversion platform 30.

[0035] Please refer to Figures 3 to 6, in order to further optimize the smoothness of the process of transferring the pipe from the climbing section to the slow-falling section, the installation height of the starting side 31 is higher than that of the ending side 32, so that the top surface of the conversion platform 30 is an inclined surface; the above continuous pipe jacking mechanism further includes a buffer platform 34, and the buffer platform 34 is arranged at an interval from the conversion platform 30 to form a falling gap 35. The falling gap 35 extends downward and cooperates with the top surface of the bearing plate 20 at the uppermost part of the slow-falling section; the side of the top surface of the buffer platform 34 close to the conversion platform 30 is the buffer side 36, and the side far from the conversion platform 30 is the return side 37; the installation height of the buffer side 36 is lower than that of the ending side 32; the buffer side 36 extends in the direction towards the return side 37 to form a horizontally arranged buffer surface 361; the installation height of the buffer surface 361 is lower than that of the return side 37 to form a return slope 371 between the buffer surface 361 and the return side 37; when the steel pipe rolls along the top surface of the conversion platform 30, it can be thrown from the ending side 32 to the buffer surface 361; the bearing plate 20 can squeeze the steel pipe located on the buffer surface 361 to make the steel pipe climb along the return slope 371. When the steel pipe crosses the bearing plate 20, the steel pipe rolls down along the return slope 371 and rolls through the buffer surface 361 and falls into the falling gap 35.

[0036] With the above settings, the pipe rises along the climbing wall 33 with the bearing plate 20 until it falls on the starting side 31, and then automatically rolls from the starting side 31 to the ending side 32 along the inclined top surface of the conversion platform 30, and then makes an oblique throwing motion and falls on the buffer surface 361 and stops after buffering. In this state, the conveying speed of the conveyor belt 10 can be adjusted arbitrarily (usually slowed down) to drive the bearing plate 20 that lifted the pipe before to gradually rotate and turn over, so as to extend the time interval for supplying the pipe. Then, the turned-over bearing plate 20 contacts and squeezes the pipe to make the pipe rise along the return slope 371 until the outside of the bearing plate 20 (including the limiting plate 21) crosses the pipe. Then, under the action of gravity, the pipe rolls down along the return slope 371, passes through the buffer surface 361 and falls into the falling gap 35. At this time, the part of the bearing plate 20 that overlaps with the falling gap 35 and previously squeezed the pipe to make it rise must be lower than the installation height of the buffer surface 361. Therefore, the pipe falls along the falling gap 35 and quickly falls on this bearing plate 20. As the bearing plate 20 continues to descend, when the pipe leaves the bottom end of the falling gap 35, the pipe rolls along the inclined bearing plate 20 towards the outer end of the bearing plate 20 and finally stops at the pipe unloading groove; with the above settings, while significantly extending the interval time for supplying the pipe, the distance for the pipe to fall (along the falling gap 35) onto the bearing plate 20 can be reduced, which not only avoids the pipe bouncing when contacting the bearing plate 20, but also avoids the unnecessary deformation of the conveyor belt 10 caused by the gravitational potential energy of the pipe pressing and bending the bearing plate 20.

[0037] In order to further optimize the falling process of the pipe in the gap 35, the gap 35 extends along the length direction of the slow-fall section and is arranged flush with the slow-fall section, so that the steel pipe can fall through the gap 35 to the side of the supporting plate 20 close to the conveyor belt 10; the buffer surface 361 is covered with a vibration-absorbing foam layer (not shown); the width of the gap 35 is slightly larger than the outer diameter of the steel pipe.

[0038] By setting the extension direction and position of the drop gap 35, the pipe falls on the inner side of the support plate 20. On the one hand, this reduces the length of the force arm acting as the support plate 20 when bearing the weight of the falling pipe, thereby reducing its impact on the conveyor belt 10. On the other hand, the inner side of the support plate 20 in the slow-fall section is set higher than the outer side. Therefore, falling on the inner side of the support plate 20 can further reduce the height of the pipe falling, further preventing it from bouncing and affecting the conveyor belt 10. The provision of a vibration-absorbing foam layer effectively prevents pipes from bouncing significantly after falling on the buffer surface 361.

[0039] In order to automatically and in large quantities supply pipes to the supporting plate 20 of the climbing section, the above-mentioned continuous pipe jacking mechanism also includes a pipe supply mechanism, which includes a vertically arranged pipe supply wall 50 and a horizontally arranged pipe supply plate 51; the pipe supply wall 50 is provided with a pipe supply interlayer 501 in the vertical direction, the width of the pipe supply interlayer 501 is slightly larger than the length of the pipe, the thickness of the pipe supply interlayer 501 is slightly larger than the diameter of the pipe, the top side of the pipe supply interlayer 501 vertically penetrates the pipe supply wall 50 to form a pipe supply inlet, the pipe supply inlet is connected to the pipe source, and the bottom side of the pipe supply interlayer 501 horizontally penetrates the pipe supply wall 50 to form a pipe supply Outlet, the height of the pipe supply outlet is slightly larger than the diameter of the pipe, and an inclined guide slope 502 is provided at the bottom corner of the pipe supply interlayer 501; one side of the pipe supply plate 51 is connected to the pipe supply wall 50, so that the top surface of the pipe supply plate 51 is flush with the bottom surface of the pipe supply outlet, and a baffle 52 is vertically provided on the side of the pipe supply plate 51 away from the pipe supply wall 50, and the distance between the baffle 52 and the pipe supply wall 50 is slightly larger than the diameter of the pipe, so as to form a pipe supply groove between the baffle 52 and the pipe supply wall 50; the outer side of the bearing plate 20 located in the climbing section is located below the side of the pipe supply groove.

[0040] With the above settings, a large number of pipes are loaded in the supply pipe sandwich layer 501, and the pipes are arranged horizontally, with adjacent pipes stacked in sequence. Therefore, the pipes above will surely exert gravity on the pipes below. The pipes at the bottom are subjected to a lateral component force under the action of the guiding slope 502, and thus move horizontally along the supply pipe plate 51 until they are blocked by the baffle 52. At this time, one pipe is filled in the supply pipe groove. When the bearing plate 20 rises along the climbing section until the top surface of its outer side contacts the bottom surface of the pipe in the supply pipe groove, the bearing plate 20 is pried upward, and then the pipe rolls from the outer side to the inner side along the bearing plate 20 and stops in the upper pipe groove. At the same time, the pipe at the bottom in the supply pipe sandwich layer 501 is automatically and quickly filled into the supply pipe groove under the gravity of the pipes above to wait for the next bearing plate 20 to pry it upward.

[0041] To facilitate the replenishment of pipes into the supply pipe sandwich layer 501, a supply pipe funnel 53 is provided at the top of the supply pipe wall 50. The supply pipe funnel 53 is surrounded by two pairs of side plates 531. The side plates 531 are inclined so that both the mouth and the bottom of the supply pipe funnel 53 are rectangular openings; the length of the mouth of the supply pipe funnel 53 is greater than the length of the pipe, and the width is greater than the diameter of the pipe; the length of the bottom of the supply pipe funnel 53 is slightly greater than the length of the pipe, and the width is slightly greater than the diameter of the pipe.

[0042] To further explain the specific structure of the pipe jacking machine 60, the pipe jacking machine 60 includes a main body 61, a pipe jacking oil cylinder 62, and a hydraulic telescopic rod 63; the main body 61 is a horizontally arranged strip, and a pipe jacking groove 611 is horizontally opened at the top of the main body 61. The two ends of the pipe jacking groove 611 penetrate the main body 61 respectively.
