Description

Technical Field

[0001] This invention relates to the field of roadbed ditch excavation and forming devices. More specifically, this invention relates to a roadbed ditch excavation and forming machine. Background Technology

[0002] The construction of roadbed drainage ditches typically involves excavating trenches with excavators, manually trimming the trenches, and then pouring concrete. The trench excavation process involves multiple pieces of equipment, including excavators, cutting machines, and dump trucks. The dump trucks move synchronously with the excavators, with each excavated section of soil being loaded into the dump truck before excavation continues. This results in a long working stroke for the robotic arms, leading to low construction efficiency. Furthermore, multiple workers are required to operate both the excavator and the dump truck. During concrete pouring, the traditional formwork method requires a large amount of formwork, necessitating multiple workers to erect the formwork and vibrate the concrete. Additionally, the sidewalls and bottom walls of the ditch need to be poured separately, resulting in high material and labor costs and a long construction period. Therefore, there is a need for a roadbed drainage ditch excavation and forming machine to address the problems of low construction efficiency and long construction cycles in existing roadbed drainage ditch construction methods.

Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1 As shown, the present invention provides a roadbed drainage ditch excavation and forming machine, comprising:

[0035] The cabin 1 has a walking mechanism 7 at its bottom, which is used to drive the cabin 1 to move along the excavation direction of the roadbed ditch;

[0036] The top of the cabin 1 is sequentially provided with a mechanical arm 3 and a cab 5 along the excavation direction of the roadbed ditch; one end of the mechanical arm 3 is rotatably connected to the cabin 1, and the other end is detachably connected to an excavation device; the cab 5 is provided with a hydraulic power device for driving the mechanical arm 3 to move in the vertical and horizontal directions.

[0037] A feeding hopper 2 is provided at one end of the cabin 1 near the robotic arm 3. The feeding hopper 2 is connected to the interior of the cabin 1. A discharge port 8 is provided on one side of the cabin 1. A conveying device 10 is provided inside the cabin 1. The material dug by the robotic arm 3 is fed into the feeding hopper 2. The conveying device 10 is used to transport the material entering the cabin 1 from the feeding hopper 2 to the discharge port 8.

[0038] A sliding formwork device is provided at the end of the cabin 1 away from the robotic arm 3. The sliding formwork device is used to pour concrete into the roadbed drainage ditch formed by the robotic arm 3 and the excavation device to form the roadbed drainage ditch.

[0039] In this technical solution, the traveling mechanism 7 is a tracked or wheeled traveling mechanism, including a drive unit and other devices to drive the tracks or wheels. It can be a conventionally used tracked or wheeled traveling mechanism in the prior art. The cabin 1 is located above the roadbed ditch to be excavated, and the traveling mechanism 7 travels along both sides of the roadbed ditch to be excavated. Along the excavation direction of the roadbed ditch, the robotic arm 3 is located at the front end of the top of the cabin 1, and the sliding formwork device is located at the rear end of the top of the cabin 1. The robotic arm 3 drives the excavation device to excavate the soil or rock. The excavated material is put into the feed hopper 2 at the front end of the cabin 1, and then the material is transported to the discharge port by the conveying device 10. Other equipment, such as a receiving trolley, is used to transport the material away from the site. Compared to having a truck or dump truck moving synchronously in front of or to the side of the entire device, the present invention allows the robotic arm 3 to directly load materials into the truck or dump truck, reducing the reciprocating range of the robotic arm 3 and improving excavation efficiency; it also eliminates the need to occupy a truck or dump truck, saving manpower and resources. Receiving materials on one side of the cabin 1 will not obstruct the movement of the entire device or affect the operator's field of vision in the cab 5. When the cabin 1 moves to a position above the already excavated roadbed ditch, concrete pouring can be carried out simultaneously through the slipform device, further improving the construction efficiency of the roadbed ditch. It is understood that the cab 5 is also equipped with a generator and a control device for generating electricity. The generator provides power to the hydraulic power equipment, the conveying equipment 10, the control device, and the traveling device 7. The control device is a conventional controller, including a control interface, which is connected to the hydraulic power equipment, the conveying equipment 10, and the traveling device 7, respectively. Operators operate the device through the control interface. Specifically, the cab 5 and the robotic arm 3 can be the same as those of an existing excavator, and the conveying device 10 can be connected to the corresponding control circuit. The robotic arm 3 can also be a conventional multi-degree-of-freedom robotic arm. The robotic arm 3 is connected to the cabin 1 through a slewing base 4, and the slewing base 4 drives the robotic arm 3 to rotate in the horizontal plane.

[0040] Considering that conventional buckets are ineffective in excavating rock formations, the excavation device includes either a bucket or a cutting machine. When excavating rock, the bucket on the robotic arm 3 is replaced with a cutting machine to cut the rock before excavating with the bucket. To reduce manual excavation, the cross-sectional shape of the bucket is matched to the cross-sectional shape of the roadbed ditch, allowing for fixed-length excavation and trench formation in one go.

[0041] In another embodiment, refer to Figure 2 The cabin 1 is a hollow rectangular cabin with a first partition 9 vertically arranged inside, dividing the interior of the cabin 1 into a material collection and conveying cabin 11 and a sliding mold cabin 12. The conveying device 10 is disposed in the material collection cabin 11, and a feed port communicating with the feed hopper 2 is opened on one side of the material collection cabin 11. To ensure the overall strength of the cabin 1, preferably, the cabin 1 can be welded from a steel structure. The cabin 1 includes a rectangular frame (not shown in the figure) welded from structural steel as a supporting structure, and then steel plates are welded to the outer periphery of the rectangular frame to form the cabin 1.

[0042] In another embodiment, refer to Figure 2 The conveying device 10 includes a first conveyor belt 101 and a second conveyor belt 103. The first conveyor belt 101 and the second conveyor belt 103 are arranged perpendicularly. The feed end of the first conveyor belt 101 is located near the feed inlet and below the feed inlet. Its discharge end is located above the feed end of the second conveyor belt 103. The discharge end of the second conveyor belt 103 is located near the discharge inlet.

[0043] The material conveying direction is switched by the vertically arranged first conveyor belt 101 and second conveyor belt 103. To prevent material from falling off the conveyor belts, baffles 102 are provided on both sides of the first conveyor belt 101 and the second conveyor belt 103 along their conveying direction. The first conveyor belt 101 and the second conveyor belt 103 can be conventional belt conveyors, which also include drive motors, etc. The overlap width between the discharge end of the first conveyor belt 101 and the feed end of the second conveyor belt 103 is 1 / 4 to 1 / 3 of the width of the second conveyor belt 103. The discharge end of the second conveyor belt 103 is located near the discharge port 8, and a downwardly inclined guide plate can also be provided on the outside of the discharge port 8 to guide the material to an external receiving device.

[0044] In another embodiment, refer to Figures 2-5The slipform chamber 12 has a second partition 120 horizontally arranged inside. The top of the slipform chamber 12 is open. A material collection hopper 6 is fixedly arranged on the second partition 120. The bottom of the material collection hopper 6 passes through the second partition 120. The bottom of the slipform chamber 12 is open. A pushing device and a template device are arranged at the bottom of the second partition 120. The pushing device and the template device are arranged on both sides of the material collection hopper 6 along the excavation direction of the roadbed ditch. The pushing device is arranged on the bottom of the second partition 120 near the side of the robotic arm 3.

[0045] In this technical solution, the second partition 120 should be positioned as close as possible to the bottom of the cabin 1 to facilitate the insertion of the slipform device into the roadbed drainage ditch. The second partition 120 divides the slipform cabin 12 into an upper space and a lower space. The aggregate hopper 6 is located in the upper space, and the second partition 120 surrounding the aggregate hopper 6 can also be used to place construction tools. The pushing device and the template device are both located in the lower space. When pouring concrete, both the pushing device and the template device extend into the roadbed drainage ditch. Concrete falls from the aggregate hopper 6 between the pushing device and the template device, and the pushing device pushes the concrete into the template device to form the roadbed drainage ditch. As the cabin 1 moves forward, the next section of the roadbed drainage ditch is continuously formed.

[0046] In another embodiment, refer to Figure 4 and Figure 6 The template device includes:

[0047] A pair of vertically arranged telescopic cylinders 111, the fixed end of any one of the telescopic cylinders 111 is slidably connected to the bottom of the second partition 120, and its movable end is fixedly connected to a top template 112; the two telescopic cylinders 111 are located in the same vertical plane, and the two top templates 112 are located in the same horizontal plane;

[0048] A pair of side templates 113, one end of which is rotatably connected to the bottom surface of a top template 112. At least one support screw 114 is provided between the pair of side templates 113. The length of the support screw 114 is adjusted to adjust the angle between the side template 113 and the top template 112.

[0049] A custom bottom mold 115 is fixedly connected to the bottom of a pair of side molds 113;

[0050] The customized end mold 118 has the same shape as the top mold 112, the side mold 113 and the customized bottom mold 115. The customized end mold 118 is disposed at one end of the top mold 112 facing the pushing device. The customized end mold 118 is vertically disposed and fixedly connected to the top mold 112, the side mold 113 and the customized bottom mold 115 respectively.

[0051] The fixed ends of a pair of telescopic cylinders 111 are slidably connected to the bottom of the second partition plate 120. The distance between the tops of the two side templates 113 corresponds to the top dimension of the roadbed ditch. The distance between the tops of the two side templates 113 is adjusted by the distance between the pair of telescopic cylinders 111. Specifically, a slide rail can be opened at the bottom of the second partition plate 120, or a slide rail can be installed at its bottom, which can be flexibly selected in actual use. The pair of telescopic cylinders 111 always extend and retract synchronously to ensure that the two top templates 112 are always in the same plane. Considering that the roadbed ditch can be rectangular or trapezoidal in actual construction, the side templates 113 are rotatably connected to the corresponding top templates 112. The included angle between the side templates 113 and the top templates 112 is adjusted according to the shape of the roadbed ditch, and the pair of side templates 113 are fixed by the support screws 114. To ensure the stability of the template device, multiple sets of support screws 114 can be set.

[0052] The customized bottom mold 115 is a bottom mold made according to the bottom dimensions of the roadbed ditch, and its width is the distance between the bottoms of the two side molds 113. The customized end mold 118 is an end mold made according to the cross-sectional dimensions of the roadbed ditch, used to seal the end of the mold device facing the pushing device to prevent concrete from entering the interior of the mold device. The distance between the bottom mold of the customized bottom mold 115 and the bottom of the roadbed ditch is adjusted by a pair of telescopic cylinders 111, which corresponds to the bottom wall 133 of the roadbed ditch after pouring, that is, the pouring thickness of the bottom wall 133 is controlled by the telescopic cylinders 111. When the pair of telescopic cylinders 111 are retracted to their shortest length, the bottom of the customized bottom mold 115 is higher than the bottom of the walking mechanism 7. When a shoulder 131 is provided on the top of the roadbed ditch, baffle plates 117 are respectively provided on both sides of the top mold. The distance between the side formwork 113 and the side wall of the roadbed drainage ditch corresponds to the side wall 132 of the roadbed drainage ditch after pouring. When the included angle between the side formwork 113 and the top formwork 112 remains unchanged, adjusting the distance between the two telescopic cylinders 111 can adjust the thickness of the side wall 132. Both the top formwork and the side formwork are reusable; only the customized bottom formwork 115 and the customized end formwork 118 need to be made according to the dimensions of the roadbed drainage ditch, effectively saving costs.

[0053] In another embodiment, refer to Figure 4Vibration devices 116 are respectively provided on one side of the pair of side templates 113 and on the top surface of the customized bottom template 115. The vibration device 116 is a vibrator used to evenly spread concrete on the forming surface of the roadbed ditch and to compact the concrete under gravity, thereby improving the quality of concrete pouring.

[0054] In another embodiment, considering that the template device is located at the bottom of the chamber 1, making it inconvenient to manually observe the concrete pouring process, multiple pressure sensors are embedded on the side of the customized end mold 118 facing the pushing device. These pressure sensors determine whether the pushing device has accurately pushed the concrete into place. The multiple pressure sensors are evenly distributed on the side of the customized end mold 118.

[0055] In another embodiment, refer to Figure 3 and Figure 5 The material pushing device includes a support plate 123, a vertical telescopic rod 124, a horizontal telescopic rod 122, and a material pushing plate 121. The shape of the material pushing plate 121 is the same as the cross-sectional shape of the roadbed ditch. The fixed end of the horizontal telescopic rod 122 is fixedly connected to the support plate 123, and its movable end is fixedly connected to the material pushing plate 121. The fixed end of the vertical telescopic rod 124 is fixedly connected to the second partition plate 120, and its movable end is fixedly connected to the support plate 123.

[0056] To ensure the stability of the support plate 123 and provide stable support for the transverse telescopic rod 122 and the pusher plate 121, multiple sets of vertical telescopic rods 124 are provided. The end face and side wall of the fixed end of the vertical telescopic rod 124 are fixedly connected to the bottom of the second partition 120 and the first partition 9, respectively. When concrete needs to be poured, the support plate 123, the transverse telescopic rod 122, and the pusher plate 121 are extended into the roadbed drainage ditch by extending the vertical telescopic rod 124. During pouring, a support block can also be placed on the side of the support plate 123 facing the robotic arm 3. When the vertical telescopic rod 124 is retracted to its shortest length, the bottom of the support plate 123 and the pusher plate 121 are higher than the bottom of the walking mechanism 7 to avoid affecting the forward movement of the entire device. The transverse telescopic rod 122 drives the pusher plate 121 to reciprocate, pushing the concrete into the space between the template device and the roadbed drainage ditch to form the concrete molding structure of the roadbed drainage ditch. Before the formal pouring, experiments are conducted to determine the magnitude of the pushing force exerted by the pusher plate 121 on the customized end mold 118 when the pusher plate 121 completely pushes a fixed amount of concrete between the formwork device and the roadbed drainage ditch. This force is measured by the pressure sensors when the pusher plate 121 pushes the mold to complete contact with the customized end mold 118. During the formal pouring, when the pushing force values ​​measured by each pressure sensor reach the experimentally determined values, the transverse telescopic rod 122 stops extending. The pusher plate 121 remains in its current position for a period of time before retracting the transverse telescopic rod 122.

[0057] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
