Description

Technical Field

[0001] The present invention relates to the technical field of piling, and in particular to a piling equipment, a piling system and a piling method. Background Art

[0002] With the rapid development of photovoltaic brackets, the application of derived photovoltaic brackets in different scenarios has become the focus of current photovoltaic bracket technology research. With the increasing number of special scenarios, photovoltaic brackets in mountainous scenarios are the most difficult to construct and install at this stage. The first problem is piling. Due to the large slope of the mountain, the commonly used pile driver cannot be driven on the hillside. In addition, the distribution of the soil layer of the mountain is mostly rock and clay, and even the soil layer of the mountain in some areas is collapsible loess. The two situations directly lead to a sharp increase in the difficulty of mountain piling. The current processing methods on the market are generally: a creeper pile driver is used for slopes with a slope of less than 40 degrees; a hand-held pile driver is used for slopes between 40° and 50°.

[0003] However, in the prior art, there are the following problems when using a creeper pile driver to pile: 1. The soil on the hillside of some project sites is very loose, and since the creeper pile driver is like a crawler vehicle, it is easy to slip on the hillside; 2. The bearing layer of the mountain in some project sites is rock. When the pile head of the creeper pile driver is pressing the pile vertically, due to the high density of the rock and soil, the pile driver is difficult to press in, and the creeper pile driver may overturn; 3. The slope of the project site cannot be too large. There are the following problems when using a hand-held pile driver: 1. It needs to be connected to electricity or an oil pump; 2. The workers are still very strenuous (especially when encountering a rock layer); 3. This method has a low degree of completion. From the perspective of the entire project, the pile foundation of the mountain will have safety hazards due to construction errors. Summary of the invention

[0049] Figure 1 The structural block diagram of the piling system 010 provided in this embodiment is as follows: Figure 2 The schematic diagram of the structure of the piling equipment 10 provided in this embodiment is as follows: Figure 3 A schematic diagram of the piling system 010 provided in this embodiment being projected on a mountain. Figure 4 This is a top view of the piling point 31 projected on the mountain by the piling system 010 provided in this embodiment. Figure 1-Figure 4 This embodiment provides a pile driving device 10 and also provides a pile driving system 010.

[0050] The piling system 010 includes a piling device 10, and the piling system 010 also includes a projection device 30. The projection device 30 is used to project piling points 31 to the target piling area, and each piling point 31 is a location to be piled. Specifically, the projection device 30 projects onto the mountain according to the preset piling points 31, and forms a plurality of light spots on the surface of the mountain through the projected light, and each light spot is a piling point 31. Since the piling points 31 are light spots, each piling point 31 has projected light, which is the positioning light received by the point determination device 320.

[0051] The pile driving device 10 includes a casing 100, a partition 211, a spark stone 212 and a trigger structure 300. The casing 100 has a first chamber 112 and a second chamber 127, and the partition 211 is placed in the second chamber 127, so as to separate the second chamber 127 into an explosion chamber 128 and a mounting groove 129, wherein the explosion chamber 128 is located between the mounting groove 129 and the first chamber 112, and the mounting groove 129 forms an opening on a side away from the explosion chamber 128 and is used to install the pile foundation 20. The spark stone 212 is arranged between the first chamber 112 and the explosion chamber 128, and is used to ignite the explosive in the explosion chamber 128, so that after the spark stone 212 is triggered, the explosive force generated by the explosive can press the pile foundation 20 down to achieve piling operation. In this process, the downward pressure of the pile foundation 20 is generated by the explosion, which consumes less manpower and does not require external power supplies or oil pumps and other large and heavy components, so it is easy to carry and convenient for piling operations on complex terrains such as mountains, and the piling difficulty is small. The trigger structure 300 is disposed in the first chamber 112, and the trigger structure 300 includes a firing pin 310 and a point position distinguishing device 320. The firing pin 310 can move relative to the casing 100 in the direction from the first chamber 112 to the second chamber 127, and is used to strike the spark stone 212. The point position distinguishing device 320 is disposed on the side of the firing pin 310 close to the second chamber 127, and the point position distinguishing device 320 is used to block the firing pin 310 from striking the spark stone 212 when it is in a blocking state, and the point position distinguishing device 320 is also used to switch to an open state when sensing positioning light, at which time the firing pin 310 can pass through the point position distinguishing device 320 under the action of an external force to strike the spark stone 212. By providing the point position distinguishing device 320, on the one hand, the safety of use can be ensured to avoid safety problems caused by false triggering, and on the other hand, the accuracy of the pile driving position can be ensured.

[0052] The piling device 10 provided in this embodiment is further described below:

[0053] Figure 5 This is a schematic diagram of the structure of the upper casing part 110 in the piling equipment 10 provided in this embodiment. Figure 6 This is a schematic diagram of the structure of the lower casing 120 in the piling equipment 10 provided in this embodiment. Figure 2 , Figure 5 and Figure 6 In this embodiment, the casing 100 is a cylindrical tube-shaped member, which includes an upper casing part 110 and a lower casing part 120 connected to each other. A first chamber 112 is formed in the upper casing part 110, and a second chamber 127 is formed in the lower casing part 120. By setting the casing 100 as a structure in which the upper casing part 110 and the lower casing part 120 are detachably connected to each other, operations such as filling gunpowder are facilitated.

[0054] The upper casing portion 110 includes an inner cylinder portion 111 and an outer cylinder portion 114 which are coaxially arranged. The inner cylinder portion 111 encloses a first chamber 112. In other words, the first chamber 112 is the inner cavity of the inner cylinder portion 111. The outer cylinder portion 114 is sleeved outside the inner cylinder portion 111, and the inner cylinder portion 111 and the outer cylinder portion 114 are spaced apart, so that a soundproof chamber 115 is formed between the inner cylinder portion 111 and the outer cylinder portion 114, which helps to reduce the noise generated during the explosion. The lower casing portion 120 is a cylindrical member with an open lower end, in which a second chamber 127 is formed, and a partition 211 is provided in the second chamber 127 to separate the explosion chamber 128 and the installation groove 129. When pile driving, the pile foundation 20 enters the installation groove 129 through the open mouth below the lower casing portion 120, so that the explosion chamber 128 is located on both sides of the partition 211. When the explosive in the explosion chamber 128 is ignited to generate an explosive force, the explosive force is applied downward to the pile foundation 20 through the partition 211, so that the pile foundation 20 is subjected to a striking force and is inserted into the ground.

[0055] Figure 7 This is a schematic diagram of the structure of the pile foundation 20 provided in this embodiment. Figure 2 , Figure 5-Figure 7 In this embodiment, the pile foundation 20 includes a pile body 21, a pile shoe 22 arranged at the lower end of the pile body 21, and a wing 23 arranged near the upper end of the pile body 21. The pile shoe 22 is conical, which helps to reduce the difficulty of piling. At the same time, when the burial depth of the pile body 21 reaches the designed burial depth, the wing 23 just contacts the soil surface. At this time, a reaction force begins to be provided to the wing 23 to resist the thrust generated by the explosion, which helps to improve the bearing capacity of the pile foundation 20. Furthermore, an iron plate 24 is welded and fixed on the top of the pile foundation 20. When an explosion occurs, the iron plate 24 can help the pile top absorb the explosion force, thereby ensuring the integrity of the pile top. It can be understood that in some other embodiments, the partition 211 can also be movably arranged in the first chamber 112.

[0056] Furthermore, the upper end of the lower casing 120 has a first plug-in portion 121, which is a cylindrical protrusion whose outer dimensions match the inner hole dimensions of the inner casing 100. When installing, the first plug-in portion 121 is inserted into the inner casing 100. The first plug-in portion 121 also has a mounting hole 122 connected to the second chamber 127, and the spark stone 212 is installed in the mounting hole 122. In this way, when the first plug-in portion 121 is plugged into the lower end of the inner casing 100, the spark stone 212 is connected to the first chamber 112, and the firing pin 310 located in the first chamber 112 can hit the spark stone 212.

[0057] Furthermore, the lower end of the outer tube portion 114 is lower than the lower end of the inner tube portion 111, and a connecting plate 117 is provided between the lower end of the inner tube portion 111 and the outer tube portion 114, through which the lower end of the soundproof chamber 115 is closed. The lower casing portion 120 also has a step portion 123, the upper end surface of the step portion 123 abuts against the lower end surface of the connecting plate 117, and the outer circumferential surface of the step portion 123 cooperates with the inner circumferential surface of the outer tube portion 114, thereby ensuring that the upper casing portion 110 and the lower casing portion 120 are accurately positioned and easy to install.

[0058] Optionally, the upper casing part 110 and the lower casing part 120 are fixed by a pin 130. Specifically, a first pin hole 116 is provided on the outer tube part 114, and a second pin hole 124 is provided on the outer circumferential surface of the step part 123. When the upper casing part 110 and the lower casing part 120 are inserted and positioned, the first pin hole 116 and the second pin hole 124 are aligned. At this time, the pin 130 is inserted into the first pin hole 116 and the second pin hole 124 to fix the upper casing part 110 and the lower casing part 120. Optionally, the upper casing part 110 and the lower casing part 120 are fixed by two pins 130. Accordingly, the upper casing part 110 has two first pin holes 116 symmetrically arranged relative to the axis, and the lower casing part 120 has two second pin holes 124 symmetrically arranged relative to the axis.

[0059] Furthermore, the step portion 123 also has a combustion oil chamber 126, and the lower end of the spark stone 212 extends into the combustion oil chamber 126. Specifically, the combustion oil chamber 126 is used to fill the combustion oil, and the explosion chamber 128 is used to fill the gunpowder. When the spark stone 212 is hit, the combustion oil is ignited, and the gunpowder is detonated by the combustion oil.

[0060] Furthermore, the lower casing part 120 also has a slag discharge hole 125 connected to the explosion chamber 128, and the waste slag generated after the explosion of the gunpowder is discharged through the slag discharge hole 125.

[0061] Figure 8 This is a partial structural diagram of the piling equipment 10 provided in this embodiment. Figure 2 and Figure 8In this embodiment, the point position distinguishing device 320 includes a stress strain rod 321 and a photosensitive heat resistance wire 322. The photosensitive heat resistance wire 322 is used to generate heat when sensing the positioning light. The stress strain rod 321 is a component whose rigidity changes with temperature. It has a first rigidity under low temperature conditions and blocks the firing pin 310. At this time, the point position distinguishing device 320 is in a blocking state; it has a second rigidity under high temperature conditions, which is less than the first rigidity. At this time, the stress strain rod 321 has a certain flexibility and can be deformed (similar to a sponge). The point position distinguishing device 320 is in an open state. At this time, the firing pin 310 can pass through the point position distinguishing device 320 to hit the spark stone 212 located below the point position distinguishing device 320.

[0062] Specifically, the photosensitive thermal resistance wire 322 is arranged close to the stress strain rod 321, and when the photosensitive thermal resistance wire 322 is heated, the stress strain rod 321 is heated. The "low temperature condition" mentioned above refers to the temperature condition of the stress strain rod 321 when the photosensitive thermal resistance wire 322 is not heated, and the rigidity of the stress strain rod 321 is the first rigidity; the "high temperature condition" mentioned above refers to the temperature condition of the stress strain rod 321 when the photosensitive thermal resistance wire 322 is heated, and the rigidity of the stress strain rod 321 is the second rigidity.

[0063] Furthermore, the point position determination device 320 also includes a first firing pin clip 324 and a second firing pin clip 325 which are coaxially arranged. The first firing pin clip 324 and the second firing pin clip 325 can both be movably mounted on the casing 100 and are located on the side of the firing pin 310 close to the second chamber 127, that is, the first firing pin clip 324 and the second firing pin clip 325 are located on the passage between the firing pin 310 and the spark stone 212. One end of the stress strain rod 321 is fixedly connected to the casing 100, and the other end of the stress strain rod 321 is fixedly connected to the first firing pin clip 324. When the stress strain rod 321 has a first rigidity, the stress strain rod 321 interferes between the first firing pin clip 324 and the casing 100, preventing the first firing pin clip 324 from moving relative to the casing 100. At this time, the first firing pin clip 324 and the second firing pin clip 325 are maintained in a mutually interfering state (such as Figure 8 As shown in the figure, the first firing pin clip 324 and the second firing pin clip 325 cut off the path of the firing pin 310 moving toward the spark stone 212, so that the firing pin 310 cannot hit the spark stone 212; when the stress strain rod 321 has the second rigidity, if the firing pin 310 moves downward and applies a force to the first firing pin clip 324 moving in a direction away from the second firing pin clip 325, the first firing pin clip 324 can push the stress strain rod 321 to deform and then move relative to the casing 100. At this time, the first firing pin clip 324 is separated from the second firing pin clip 325 and a gap is formed between the first firing pin clip 324 and the second firing pin clip 325 for the firing pin 310 to pass through.

[0064] Specifically, the first firing pin clip 324 and the second firing pin clip 325 have the same structure and both include a rod 326 and a return spring 327. When the firing pin 310 moves downward and contacts the first firing pin clip 324 and the second firing pin clip 325 to push the first firing pin clip 324 and the second firing pin clip 325 to move in the opposite direction, the return spring 327 is compressed. After the firing pin 310 moves upward and disengages from the first firing pin clip 324 and the second firing pin clip 325, the first firing pin clip 324 and the second firing pin clip 325 are respectively returned to their original positions by the action of their respective return springs 327.

[0065] Furthermore, the trigger structure 300 also includes a position indicator light 323 electrically connected to the position identification device 320. When the position identification device 320 is in the on state, the position indicator light 323 lights up to indicate that the piling operation can be performed. Fig.10 The operation flow chart of the piling system 010 is shown, and will be described in detail later.

[0066] Fig. 9 This is a schematic diagram of the structure of the firing pin 310 in the piling device 10 provided in this embodiment. Figure 2 , Figure 8 and Fig. 9 In this embodiment, the firing pin 310 includes a pin rod 311 and a pin head 312 fixedly connected to the lower end of the pin rod 311. The pin head 312 has a first end, a middle part, and a second end, which are sequentially distributed along the moving direction of the firing pin 310. The width of the first end and the width of the second end are both smaller than the width of the middle part, and the width is the dimension along the moving direction of the first firing pin clamp 324 and the second firing pin clamp 325. That is, the pin head 312 is a spindle-shaped structure with small ends and a large middle part, and the middle part is the position where the pillow has the largest width. When the pin head 312 pushes the first firing pin clamp 324 and the second firing pin clamp 325 away, and the contact position of the pin head 312 with the first firing pin clamp 324 and the second firing pin clamp 325 exceeds the middle part, under the thrust of the return spring 327 of the firing pin 310 clamp, the firing pin 310 will quickly drop and hit the spark stone 212.

[0067] Furthermore, a through hole 113 is provided at the top of the casing 100, and the upper end of the firing pin 310 is passed through the through hole 113, and the end of the firing pin 310 extends out of the casing 100, so that a downward pressure can be applied outside the casing 100 to move the firing pin 310 toward the spark stone 212. Furthermore, the pile driving device 10 also includes a spring member 313 provided in the first chamber 112, one end of the spring member 313 is connected to the firing pin 310, and the other end of the spring member 313 is connected to the casing 100, so as to apply a resilient force to the firing pin 310 to reset.

[0068] Specifically, the inner tube portion 111 is a cylindrical member with a through hole 113 at the upper end and an open lower end. The firing pin 310 is installed on the inner tube portion 111, and the upper end of the needle rod 311 is penetrated by the through hole 113 and extends out of the upper protective tube portion 110; a plurality of connecting clips 314 are fixed to the lower end of the needle rod 311, and the connecting clips 314 are engaged with the spring member 313, so that when the firing pin 310 moves downward under the external force, the spring member 313 is pulled to extend. On the one hand, the spring member 313 can drive the firing pin 310 to reset after the firing pin 310 collides with the spark stone 212. On the other hand, the spring member 313 can generate resistance to the downward movement of the firing pin 310. When the firing pin 310 is pressed by mistake, the downward pressure on the firing pin 310 is small and balanced by the spring member 313, thereby preventing the firing pin 310 from accidentally touching the spark stone 212.

[0069] The embodiment of the present invention further provides a piling method, which is implemented based on the piling system 010. Specifically, Fig.10 As shown, the piling method comprises:

[0070] S01: Projecting the piling point 31 to the target piling area.

[0071] Through the projection device 30, the target piling area, for example Figure 3 The pile driving points 31 are projected onto the mountain as shown, thereby forming a plurality of projection light spots on the mountain.

[0072] S02 : Install the pile foundation 20 at the piling equipment 10 , and place the piling equipment 10 at the piling point 31 .

[0073] The upper end of the pile foundation 20 is inserted into the second chamber 127 , and the piling device 10 is moved to the piling point 31 .

[0074] S3: Determine the state of the point determination device 320.

[0075] The state of the point position determination device 320 is determined according to the situation of the point position indicator light 323. When the point position indicator light 323 is on, it means that the pile driving equipment 10 is precisely located at the pile driving point 31. At this time, the photosensitive heat resistance wire 322 senses the positioning light and generates heat, so that the stress strain rod 321 is in the second stiffness. At this time, the point position determination device 320 is in the open state, and an external force can be applied to the firing pin 310 so that the firing pin 310 hits the spark stone 212 to trigger the explosion of the explosive for pile driving. When the point position indicator light 323 is not on, it means that the position of the pile driving equipment 10 is offset from the point position. At this time, the point position determination device 320 is in a blocking state, and the position of the pile driving equipment 10 can be manually adjusted until the point position indicator light 323 is on.

[0076] The piling device 10, piling system 010 and piling method provided by the embodiment of the present invention use the thrust generated by gunpowder blasting to press the pile foundation 20 into the soil to achieve the piling operation. On the one hand, the difficulty of piling is reduced. The operator only needs to move the piling device 10 to the piling point 31 and press the firing pin 310. On the other hand, the piling device 10 is more portable and does not require complex external power such as an external power supply and an oil pump. At the same time, the piling point 31 is determined by projection of the projection device 30, and the position of the piling device 10 is determined in combination with the point determination device 320, so as to ensure that the piling point 31 has no deviation and the piling position has high accuracy.

[0077] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in the field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
