Automatic pipe pushing operation equipment and green construction method

Abstract

This invention relates to the field of municipal engineering technology and discloses automated pipe jacking equipment and a green construction method. The equipment includes a base plate, a support plate, and a support frame. The base plate is equipped with a pushing component, a supporting component, and two sets of symmetrically arranged fine-tuning components. Each fine-tuning component includes a support slide, a moving plate, a drive mechanism, and an anchoring assembly. The anchoring fulcrum can drive the base plate to move, ensuring the support plate is tightly fitted against the inner wall of the pit. The supporting component employs a gravity-triggered purely mechanical clamping structure to achieve automatic pipe alignment and lateral positioning. In this invention, the fine-tuning components allow the anchoring assembly's rod to be inserted into the soil to form a fixed reaction fulcrum. The drive mechanism then moves the base plate, automatically ensuring the support plate is tightly fitted against the inner wall of the pit, thus solving the problem of insufficient fit between the equipment's support plate and the pit wall in existing pipe jacking construction methods.

Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, and in particular to automated pipe jacking propulsion equipment and green construction methods. Background Technology

[0002] In the field of municipal engineering, automated pipe jacking propulsion equipment is widely used in various underground pipeline laying projects, such as the laying of urban water supply, drainage, gas, electricity, and communication pipelines. These projects often need to be carried out in complex geological conditions and limited space, which places extremely high demands on the precision and stability of the equipment.

[0003] During pipe jacking construction, the overall positioning accuracy of the equipment is crucial. On the one hand, after the equipment is hoisted in, the support plate cannot be tightly attached to the inner wall of the pit, leaving a certain gap. This requires frequent adjustments to the equipment position or pouring concrete into the gap. If the support plate of the pipe jacking equipment cannot be tightly attached to the inner wall of the pit, the equipment will shake or shift due to uneven force when pushing the pipe. This will not only affect the laying accuracy of the pipe but also cause the pipe to deviate from its intended position. On the other hand, the pipe support mechanism lacks an automatic centering and limiting function, requiring manual adjustment within a limited space. As a result, the alignment of the pipe is often difficult to achieve an ideal state. Summary of the Invention

[0011] Furthermore, the clamping assembly includes a flipping frame, a connecting frame, side clamps, and a fixed frame fixed to the transmission plate; the middle part of the flipping frame is hinged to the top inner wall of the support frame, the bottom of the flipping frame is rotatably connected to the connecting frame, the two sides of the connecting frame are slidably connected to the fixed frame, and the side clamps are fixed to the top of the flipping frame.

[0012] Furthermore, the inner side of the arc-shaped support plate is rotatably connected to several bottom guide wheels, and the side clamp plate is rotatably connected to several side guide wheels on the side facing the arc-shaped support plate.

[0013] Furthermore, a tension spring is provided between the connecting frame and the mounting frame.

[0014] Furthermore, it also includes a bottom support plate, the top of which is provided with a sliding groove, and the bottom of the base plate is fixedly connected with a slide rail, the slide rail and the sliding groove being slidably engaged.

[0015] Furthermore, it also includes a controller, which is electrically connected to the drive mechanism, the anchor assembly, and the push component, respectively.

[0016] The green construction method for automated pipe jacking propulsion equipment includes the following steps:

[0017] Step S1: Place the bottom support plate horizontally in the preset installation position in the foundation pit. Slide the two sets of slide rails that are symmetrically fixed at the bottom of the bottom plate into the two sets of slide grooves that are symmetrically opened at the top of the bottom support plate to complete the sliding assembly of the bottom plate and the bottom support plate, so that the bottom plate can slide along the slide groove of the bottom support plate. Then move the assembled equipment to the preset construction position in the foundation pit, so that the backing plate on one side of the bottom plate is close to the target support inner wall of the foundation pit.

[0018] Step S2: Activate the electric push rod at the top of the support box in the fine-tuning component, control the output shaft of the electric push rod to extend vertically downward, drive the connecting plate to slide vertically downward in the support box, so that the plug fixed at the bottom of the connecting plate passes through the corresponding through hole on the moving plate and is vertically inserted into the soil at the bottom of the foundation pit, forming a fixed reaction fulcrum, and completing the position locking of the moving plate.

[0019] Step S3: Start the drive motor in the drive mechanism, control the output shaft of the drive motor to drive the transmission screw to rotate coaxially, and drive the moving plate to move along the support slide through the threaded transmission of the transmission screw and the transmission nut. With the help of the reaction force of the reaction fulcrum formed by the insertion rod and the soil, drive the bottom plate to move smoothly along the slide groove of the bottom support plate, so that the back plate on one side of the bottom plate is completely and tightly attached to the inner wall of the target support of the foundation pit.

[0020] Step S4: According to the length and diameter of the pipe to be laid, start multiple sets of adjusting hydraulic cylinders between the backing plate and the first support plate, control the extension and retraction end of the adjusting hydraulic cylinder to drive the first support plate to slide along the support frame, and simultaneously adjust the initial jacking position of the transmission hydraulic cylinder fixed on the first support plate and the second support plate fixedly connected to the extension and retraction end of the transmission hydraulic cylinder, so that the second support plate and the end position of the pipe to be laid correspond precisely.

[0021] Step S5: The pipe to be laid is lifted smoothly using hoisting equipment and slowly lowered onto the arc-shaped support plate at the top of the mounting frame in the support component. Multiple sets of bottom guide wheels, which are rotatably installed on the inner side of the arc-shaped support plate, provide bottom rolling support for the pipe. The self-weight of the pipe drives the mounting frame to move vertically downward along the support frame, which in turn drives the transmission plate inside the support frame to move downward synchronously. The transmission plate drives the connecting frame to move downward, and the connecting frame slides in the fixed frame, thereby pulling the corresponding flipping frame to rotate around its hinge point with the support frame toward the arc-shaped support plate. This causes the side clamping plates at the top of the two flipping frames to move closer together. Multiple sets of side guide wheels, which are rotatably installed on the inner side of the side clamping plates, provide lateral rolling support and lateral limitation for the pipe. At the same time, the tension spring between the connecting frame and the mounting frame is stretched accordingly to assist in clamping and centering the pipe.

[0022] Step S6: Activate multiple sets of transmission hydraulic cylinders on the first support plate, control the telescopic ends of the multiple sets of transmission hydraulic cylinders to extend synchronously, drive the second support plate to move smoothly along the support frame, apply a uniform jacking force to the end of the pipe through the push plate on the second support plate, drive the pipe to advance at a uniform speed into the soil outside the foundation pit along the guide channel formed by the bottom guide wheel of the arc-shaped support plate and the side guide wheel of the side clamp plate, and complete the underground laying operation of the pipe.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this invention, by setting up a fine-tuning component, the insertion rod of the anchoring component can be inserted into the soil to form a fixed reaction force fulcrum. Then, the driving mechanism drives the bottom plate to move, so that the backing plate automatically and tightly fits the inner wall of the foundation pit. There is no need to frequently adjust the equipment position or pour concrete, thereby solving the problem of uneven force and swaying and deviation during the equipment jacking process, greatly improving the accuracy of pipeline laying, and reducing the generation of construction waste, which meets the requirements of green construction.

[0025] 2. In this invention, the supporting component adopts a gravity-triggered, purely mechanical automatic clamping structure. After the pipe is hoisted to the arc-shaped support plate, it can drive the transmission plate to move down by its own weight. Through the linkage transmission between the connecting frame and the flipping frame, the two side clamping plates automatically move towards each other, completing the automatic centering and lateral limiting of the pipe, improving the centering accuracy of the pipe, ensuring that the pipe maintains a straight line during the jacking process, and requiring no additional power source or manual intervention throughout the process. It is perfectly suited to the limited space operation scenario of narrow foundation pits in municipal engineering, and greatly reduces the safety risks of manual operation.

[0026] 3. In this invention, both the arc-shaped support plate and the side clamping plate are equipped with guide wheels, which can convert the sliding friction during the pipe jacking process into rolling friction, greatly reducing the jacking resistance, reducing the energy consumption of the jacking equipment, and avoiding wear on the outer wall of the pipe, thus improving the quality of pipe laying; the tension spring set between the connecting frame and the mounting frame can not only help improve the stability of the clamping limit, but also drive the clamping components to automatically reset after the pipe is lifted off, forming a complete operation closed loop.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example

[0037] Reference Figure 1-7 An embodiment of the present invention provides an automated pipe jacking propulsion device, including a base plate 1, a backing plate 2 fixedly welded to one side of the base plate 1, the backing plate 2 being used to fit against the inner wall of the foundation pit and provide reaction force support for the equipment jacking operation; a support frame 3 fixedly welded to the top of the base plate 1, the support frame 3 being a frame structure, providing guidance and support for the jacking operation.

[0038] like Figure 1 and Figure 3As shown, a pushing component is provided on the side of the backing plate 2 away from the inner wall of the pit. The pushing component is used to push the pipe forward to complete the laying operation. The pushing component includes a first support plate 4, four sets of adjusting hydraulic cylinders 5, four sets of transmission hydraulic cylinders 6, and a second support plate 7. The left and right ends of the first support plate 4 are slidably connected to the inner sliding groove of the support frame 3. The four sets of adjusting hydraulic cylinders 5 are arranged in a rectangular symmetrical manner. The cylinder body of the adjusting hydraulic cylinder 5 is fixedly connected to the backing plate 2. The telescopic end of the adjusting hydraulic cylinder 5 is fixedly connected to the first support plate 4. The four sets of transmission hydraulic cylinders 6 are fixedly installed in a rectangular symmetrical manner on the side of the first support plate 4 facing the supporting component. The second support plate 7 is fixedly connected to the telescopic end of the transmission hydraulic cylinder 6. The left and right ends of the second support plate 7 are slidably connected to the inner sliding groove of the support frame 3. A pushing plate 8 is fixedly welded to the side of the second support plate 7 facing the supporting component.

[0039] During operation, the adjusting hydraulic cylinder 5 can drive the first support plate 4 to move, and adjust the initial jacking position of the transmission hydraulic cylinder 6 and the second support plate 7 to adapt to pipes of different lengths; the transmission hydraulic cylinder 6 can drive the second support plate 7 and the push plate 8 to move, providing power for pipe jacking.

[0040] like Figure 1 and Figure 2 As shown, a support component is provided at the top of the base plate 1 and behind the pushing component. The support component is used to support the pipe to be laid and to realize the automatic centering and limiting of the pipe. The support component includes a support frame 9, a transmission plate 10, a mounting frame 15, an arc-shaped support plate 17, and two sets of symmetrically arranged clamping assemblies. The support frame 9 is a box structure with an open top and is fixedly welded to the top of the base plate 1. The transmission plate 10 is vertically slidably installed in the inner cavity of the support frame 9. The bottom end of the mounting frame 15 is fixedly welded to the top of the transmission plate 10. The top end of the mounting frame 15 extends upward through the through hole at the top of the support frame 9 and extends to the outside of the support frame 9. The arc-shaped support plate 17 is fixedly welded to the top end of the mounting frame 15. The arc of the arc-shaped support plate 17 is adapted to the arc of the outer wall of the pipe to be laid. Multiple sets of bottom guide wheels 18 are rotatably connected to the inner side of the arc-shaped support plate 17 to form bottom rolling support for the pipe.

[0041] like Figure 5As shown, two sets of clamping components are symmetrically hinged to the inner wall of the support frame 9. Each set of clamping components includes a flipping frame 12, a connecting frame 11, a side clamping plate 13, and a fixing frame 16. The fixing frame 16 is fixedly welded to the top of the transmission plate 10. The middle part of the flipping frame 12 is hinged to the top inner wall of the support frame 9 through a pin. The top of the support frame 9 has two sets of symmetrical movable holes. The upper part of the flipping frame 12 passes through the corresponding movable holes and extends to the outside of the support frame 9. The side clamping plate 13 is fixedly welded to the top of the flipping frame 12. The side clamping plate 13 is rotatably connected to multiple sets of side guide wheels 14 on the side facing the center of the arc-shaped support plate 17. The bottom of the flipping frame 12 is rotatably connected to the connecting frame 11 through a pin. The two sides of the connecting frame 11 are slidably connected to the inner sliding groove of the fixing frame 16. A tension spring 19 is connected between the connecting frame 11 and the mounting frame 15. One end of the tension spring 19 is fixedly connected to the connecting frame 11, and the other end is fixedly connected to the side wall of the mounting frame 15.

[0042] During operation, the pipe is hoisted onto the arc-shaped support plate 17. The pipe's own weight causes the mounting frame 15 and the transmission plate 10 to move vertically downwards. The transmission plate 10 drives the fixed frame 16 to move downwards synchronously. The connecting frame 11 slides within the fixed frame 16 and moves downwards accordingly, pulling the flipping frame 12 to rotate around the hinge point in the middle towards the arc-shaped support plate 17. This causes the side clamps 13 at the top of the two flipping frames 12 to move towards each other. The side guide wheels 14 provide lateral rolling support and lateral limitation for the pipe, achieving automatic alignment of the pipe. After the pipe is hoisted off the arc-shaped support plate 17, the tension spring 19 rebounds, causing the connecting frame 11 and the flipping frame 12 to reset, preparing for the next operation.

[0043] like Figure 4 As shown, two sets of fine-tuning components are symmetrically installed on the top of the base plate 1 to adjust the position of the base plate 1 so that the backing plate 2 fits tightly against the inner wall of the pit. The fine-tuning components include a support slide cover 20, a moving plate 21, a drive mechanism, and an anchor assembly. The support slide cover 20 is a box structure with an opening on one side, which is fixedly welded to the top of the base plate 1. The moving plate 21 is slidably connected to the inner sliding groove of the support slide cover 20. The fixed end of the drive mechanism is fixedly connected to the base plate 1, and the transmission end of the drive mechanism is threadedly connected to the moving plate 21. The anchor assembly is installed on the moving plate 21.

[0044] like Figure 6As shown, the drive mechanism includes a drive motor 26, a transmission screw 27, a drive plate 28, and a transmission nut 29. The drive motor 26 is a forward and reverse servo motor, and its body is fixed to the top of the base plate 1 by bolts. One end of the transmission screw 27 is coaxially fixedly connected to the output shaft of the drive motor 26 through a coupling, and the other end of the transmission screw 27 is rotatably connected to the side wall of the support slide 20 through a bearing seat. The drive plate 28 is fixedly welded to the top of the moving plate 21, and the transmission nut 29 is fixedly welded to the drive plate 28. The transmission screw 27 passes through the transmission nut 29, and the transmission screw 27 and the transmission nut 29 are threadedly engaged. During operation, the drive motor 26 drives the transmission screw 27 to rotate, which in turn drives the drive plate 28 and the moving plate 21 to move along the support slide 20 through threaded transmission.

[0045] like Figure 7 As shown, the anchor assembly includes a support box 22, an electric push rod 23, a connecting plate 24, and an insertion rod 25. The support box 22 is fixedly welded to the top of the movable plate 21. The electric push rod 23 is vertically fixedly installed on the top of the support box 22. The output shaft of the electric push rod 23 extends into the inner cavity of the support box 22. The connecting plate 24 is fixedly welded to the end of the output shaft of the electric push rod 23. The connecting plate 24 is vertically slidably connected to the inner wall of the support box 22. The top end of the insertion rod 25 is fixedly welded to the bottom of the connecting plate 24. The movable plate 21 has a through hole corresponding to the position of the insertion rod 25. The insertion rod 25 can pass through the through hole and extend vertically downward out of the movable plate 21, inserting into the soil at the bottom of the foundation pit to form a reaction fulcrum.

[0046] Two sets of symmetrical slide rails 30 are fixedly welded to the bottom of the base plate 1, and a bottom support plate 31 is also provided. The top of the bottom support plate 31 has a slide groove that corresponds to the slide rail 30. The slide rail 30 is embedded in the corresponding slide groove, and the slide rail 30 slides in conjunction with the slide groove to provide guidance for the position adjustment of the base plate 1.

[0047] The equipment also includes a controller, preferably a PLC programmable logic controller. The controller is electrically connected to the drive motor 26, the electric push rod 23, the electromagnetic control valve of the regulating hydraulic cylinder 5, and the electromagnetic control valve of the transmission hydraulic cylinder 6, respectively, and is used to control each component to complete the automated jacking operation according to a preset program.

[0048] This embodiment also provides a green construction method for automated pipe jacking equipment, applied to the aforementioned automated pipe jacking equipment, including the following steps:

[0049] Step S1, Equipment Installation and Preliminary Positioning: Place the bottom support plate 31 horizontally in the preset installation position in the foundation pit. Slide the two sets of slide rails 30, which are symmetrically fixed at the bottom of the bottom plate 1, into the two sets of slide grooves symmetrically opened at the top of the bottom support plate 31 to complete the sliding assembly of the bottom plate 1 and the bottom support plate 31, so that the bottom plate 1 can slide along the slide groove of the bottom support plate 31. Then, move the assembled equipment to the preset construction position in the foundation pit using hoisting equipment, so that the backing plate 2 on one side of the bottom plate 1 is close to the target support inner wall of the foundation pit.

[0050] Step S2, Fixing the fulcrum of the fine-tuning component: The controller starts the electric push rod 23 at the top of the support box 22 in the fine-tuning component, controls the output shaft of the electric push rod 23 to extend vertically downward, drives the connecting plate 24 to slide vertically downward in the support box 22, so that the insertion rod 25 fixed at the bottom of the connecting plate 24 passes through the corresponding through hole on the moving plate 21 and is vertically inserted into the soil at the bottom of the foundation pit, forming a fixed reaction fulcrum, and completing the position locking of the moving plate 21;

[0051] Step S3, Automated fine-tuning of the base plate position: The controller starts the drive motor 26 in the drive mechanism, and controls the output shaft of the drive motor 26 to drive the transmission screw 27 to rotate coaxially. Through the threaded transmission of the transmission screw 27 and the transmission nut 29, the moving plate 21 is moved along the support slide cover 20. At this time, the moving plate 21 is locked with the soil through the insertion rod 25. With the reaction force of the reaction fulcrum, the base plate 1 is moved smoothly along the slide groove of the bottom support plate 31, so that the backing plate 2 on one side of the base plate 1 is completely and tightly attached to the inner wall of the target support of the foundation pit, thus completing the precise positioning of the equipment.

[0052] Step S4, Initial position adjustment of the pushing component: According to the length and diameter of the pipe to be laid, the controller starts the four sets of adjusting hydraulic cylinders 5 between the back plate 2 and the first support plate 4, and controls the extension and retraction end of the adjusting hydraulic cylinder 5 to drive the first support plate 4 to slide along the support frame 3. Simultaneously adjust the initial jacking position of the transmission hydraulic cylinder 6 fixed on the first support plate 4 and the second support plate 7 fixedly connected to the extension and retraction end of the transmission hydraulic cylinder 6, so that the pushing plate 8 on the second support plate 7 corresponds precisely to the end position of the pipe to be laid.

[0053] Step S5, Pipeline hoisting and automatic support limiting: The pipeline to be laid is smoothly hoisted using hoisting equipment and slowly lowered onto the arc-shaped support plate 17 at the top of the mounting frame 15 in the support component. Multiple sets of bottom guide wheels 18, which are rotatably installed on the inner side of the arc-shaped support plate 17, provide bottom rolling support for the pipeline. The pipeline's own weight drives the mounting frame 15 to move vertically downward along the support frame 9, causing the transmission plate 10 inside the support frame 9 to move downward synchronously. The transmission plate 10 then causes the fixed frame 16 to move downward synchronously, and the connecting frame 11... The pipe slides within the fixed frame 16 and moves downwards, thereby pulling the corresponding flipping frame 12 around the hinge point between its middle part and the support frame 9 toward the arc-shaped support plate 17. This causes the side clamping plates 13 at the top of the two flipping frames 12 to move closer together. Multiple sets of side guide wheels 14, which are rotatably installed inside the side clamping plates 13, provide lateral rolling support and limit the pipe. At the same time, the tension spring 19 between the connecting frame 11 and the mounting frame 15 is stretched accordingly, which helps to complete the clamping and centering of the pipe and ensures that the pipe maintains linear movement during the jacking process.

[0054] Step S6, Automated Pipeline Jacking Operation: The controller starts the four sets of transmission hydraulic cylinders 6 on the first support plate 4, and controls the telescopic ends of the four sets of transmission hydraulic cylinders 6 to extend synchronously, driving the second support plate 7 to move smoothly along the support frame 3. The push plate 8 on the second support plate 7 applies a uniform jacking force to the end of the pipeline, driving the pipeline to advance at a uniform speed into the soil outside the pit along the guide channel formed by the bottom guide wheel 18 of the arc-shaped support plate 17 and the side guide wheel 14 of the side clamp plate 13, completing the underground laying operation of a single section of pipeline; by repeating the above pipeline hoisting, limiting, and jacking steps, the continuous laying operation of long-distance pipelines can be completed.
