Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mountain photovoltaic pile foundation engineering, and particularly relates to a photovoltaic pile foundation drilling device for mountains. BACKGROUND

[0002] ‌Mountain photovoltaic refers to a photovoltaic power station constructed in mountainous or hilly areas. Compared with photovoltaic power stations in plain areas, mountain photovoltaic power stations face more complex topographic and climatic conditions, but at the same time have higher power generation efficiency, less land occupation and other unique advantages and characteristics. The construction of a photovoltaic power station pile foundation includes processes such as line measurement, foundation center positioning, drilling a pile foundation hole, placing a reinforcement cage, installing a formwork, placing a pre-embedded part, pouring concrete, removing the formwork, and maintenance.

[0003] Among them, drilling a pile foundation hole refers to drilling a hole on the ground with a drilling device that meets the requirements of depth, size and verticality. However, due to the influence of topographic conditions, especially when construction is carried out on a steep slope, it is difficult to maintain stable construction of the drilling device placed on the slope surface, and it is also difficult to control the drilling head to be vertically downward during drilling. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a photovoltaic pile foundation drilling device for mountains to solve the problem that when construction is carried out on a steep slope, it is difficult to maintain stable construction of the drilling device placed on the slope surface, and it is also difficult to control the drilling head to be vertically downward during drilling.

[0005] According to the embodiments of the present application, the following technical solutions are adopted:

[0006] The photovoltaic pile foundation drilling device for mountains comprises a walking mechanism and a drilling mechanism mounted on the walking mechanism. The walking mechanism comprises a mounting plate and walking wheels mounted on the mounting plate. The tail end of the mounting plate is hingedly connected with a telescopic ground supporting rod. The drilling mechanism comprises a drilling frame hingedly connected to the mounting plate and a drilling member mounted on the drilling frame. A first level gauge is mounted on the top surface of the drilling frame. The mounting plate is provided with a limiting piece for limiting the angle of the drilling frame. The drilling mechanism further comprises a detection assembly for detecting the verticality of drilling. The detection assembly comprises a detection frame for anchoring on the ground, a detection ring mounted on the detection frame, and a rotating ring rotatably connected to the upper part of the drilling member. A sliding rod is vertically slidably connected to the detection frame. The detection ring is detachably connected to the sliding rod. The detection ring is sleeved on the outer side of the upper part of the drilling member. The detection ring comprises two half rings that are detachably connected together. A plurality of pressing rods for pressing the detection ring are fixed on the rotating ring in the circumferential direction. A pressure sensor is mounted on the pressing rod.

[0007] Compared with the prior art, the present application has the following advantages:

[0008] 1. Install a deflectable and retractable ground support rod at the tail end of the mounting plate. When the traveling mechanism stops on the slope, the ground support rod is deflected and retracted, so that the ground support rod abuts against the ground at the tail end of the traveling mechanism, increasing the friction of the traveling mechanism backward, preventing the traveling mechanism from moving backward on the slope, and improving the stability of the drilling process of the drilling mechanism.

[0009] 2. Rotate the drill frame to adjust it to a vertically downward position, so that the drilling component can drill vertically downward. Use the first level to check the angle of the drill frame to determine whether the drill frame has deflected to a vertically downward position.

[0010] 3. By anchoring the testing frame to the ground, ensuring it is vertically downward, and adjusting the angle of the drill frame, the testing ring is placed on the outside of the drilling component, and the pressure rod is pressed against the testing ring. When both the testing frame and the drill frame are vertically downward, the pressure signals detected by the pressure sensors on the multiple pressure rods are consistent, which can be used to assist the first level and control the angle adjustment of the drill frame.

[0011] During drilling, when the drill bit encounters a hard object (such as a rock) in the soil, it may cause the drill bit to tilt or deflect. At this time, the pressure signals of the pressure sensors on multiple pressure rods will change. Even if the drill frame does not actually deflect, this can be used to detect whether there is a problem in the drilling process.

[0012] Furthermore, gripping components are installed on the wheels.

[0013] Furthermore, the gripping component includes a mounting plate rotatably connected to the side of the wheel, with several gripping blades hinged to the mounting plate along its circumference. The gripping blades are arc-shaped, and the arc-shaped trend of the gripping blades is consistent with the rotational trend of the wheel as it moves forward.

[0014] Furthermore, a support plate is hinged to the end of the support rod, and several anchor rods are detachably connected to the support plate.

[0015] Furthermore, a rotating shaft is rotatably connected to the testing frame, and a connecting rope is wound around the outside of the rotating shaft. One end of the connecting rope is fixed to the rotating shaft, and the other end of the connecting rope is fixed to the testing ring.

[0016] Furthermore, a second level is installed on the detection ring.

[0017] Furthermore, the compression bar is a telescopic structure.

[0018] Furthermore, the limiting component includes a slide plate slidably connected to the mounting plate, a telescopic limiting rod hinged between the slide plate and the drill frame, and a drive rod for driving the slide plate to slide on the mounting plate. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments are given.

[0024] like Figure 1 , Figure 2 As shown, the photovoltaic pile foundation drilling equipment for mountainous areas includes a walking mechanism and a drilling mechanism installed on the walking mechanism. The walking mechanism includes a mounting plate 1 and walking wheels 2 installed on the mounting plate 1. In actual design, three or four walking wheels 2 are selected, that is, the walking mechanism is a three-wheeled trolley or a four-wheeled trolley, which is designed according to the actual situation. In actual use, a traction device (such as a winch) can be set at the front end of the mounting plate 1 to pull the mounting plate 1 to move and adjust the position of the mounting plate 1 on the slope. During the drilling process, the traction device can also be anchored on the slope to increase the stability of the walking mechanism on the slope.

[0025] The rear end of the mounting plate 1 is hinged with a retractable ground support rod 9. The rear end refers to the rear end of the traveling mechanism in the direction of travel. Multiple ground support rods 9 can be set to improve the limiting support effect. In this embodiment, the ground support rod 9 is a conventional electric telescopic rod in the prior art. By extending and retracting the ground support rod 9, it is easy to adjust the position of the ground support rod 9 in contact with and support the ground. When the traveling mechanism stops on the slope, by deflecting and extending and retracting the ground support rod 9, the ground support rod 9 is made to abut against the ground at the rear end of the traveling mechanism, increasing the friction force of the traveling mechanism backward, preventing the traveling mechanism from retreating on the slope, and improving the stability of the drilling process of the drilling mechanism.

[0026] In order to improve the supporting effect of the supporting rod 9, the supporting plate 10 is hinged at the end of the supporting rod 9, and a plurality of anchor rods 11 are detachably connected to the supporting plate 10. The supporting plate 10 is used to increase the contact area with the ground and better support on the ground. The anchor rod 11 is bolted to the supporting plate 10. In actual use, when the anchor rod 11 is screwed into the supporting plate 10, it can also be wedged into the ground, so that the supporting plate 10 is fixed to the ground, and the walking mechanism has better limiting effect.

[0027] The drilling mechanism comprises a drill frame 7 hinged to the mounting plate 1 and a drilling part mounted on the drill frame 7. A first level meter is mounted on the top surface of the drill frame 7. The first level meter is selected from the instruments for detecting the level in the prior art. The first level meter is mounted on the top surface of the drill frame 7 (referring to the top when the drill frame 7 is in a vertical state, i.e. the state shown in the figure) Figure 2 The drilling part can be selected from the drill bit 15 of the conventional drilling equipment in the prior art. In this embodiment, a design method is given. The drilling part comprises a driving plate 12 slidably connected to the drill frame 7 in the axial direction of the drill frame 7. A connecting rod 14 is rotatably connected to the driving plate 12. The drill bit 15 is fixed to the connecting rod 14. A cylinder for driving the driving plate 12 to slide is mounted on the drill frame 7. A motor for driving the connecting rod 14 to rotate is mounted on the driving plate 12, so as to realize the rotation of the drill bit 15 while moving in the axial direction. In this embodiment, the drilling method and principle are not improved. The drill frame 7 is only used to adjust the angle of the drilling part. After the angle adjustment is completed, other conventional drilling methods in the prior art can be used for drilling.

[0028] A motor for driving the drill frame 7 to rotate is mounted on the mounting plate 1. A limiting part for limiting the angle of the drill frame 7 is arranged on the mounting plate 1. Specifically, the limiting part comprises a sliding plate 5 slidably connected to the mounting plate 1. A telescopic limiting rod 6 is hinged between the sliding plate 5 and the drill frame 7. The limiting rod 6 is selected from the electric telescopic rod in the prior art. A driving rod 8 for driving the sliding plate 5 to slide is mounted on the mounting plate 1. Specifically, a cylinder for driving the driving rod 8 to slide is mounted on the mounting plate 1. During the process of adjusting the angle of the drill frame 7 by the motor, the extension length of the limiting rod 6 and the sliding position of the sliding plate 5 are adjusted synchronously, so that the limiting rod 6 and the sliding plate 5 are adapted to the angle of the drill frame 7. After the angle adjustment of the drill frame 7 is completed, the extension length of the limiting rod 6 and the sliding position of the sliding plate 5 remain unchanged. Then, a stable triangle is formed between the limiting rod 6, the drill frame 7 and the mounting plate 1. The limiting rod 6 supports and limits the drill frame 7.

[0029] The drilling mechanism further comprises a detection assembly for detecting the verticality of the drilling, the detection assembly comprising a detection frame 13 for anchoring on the ground, a detection ring 20 mounted on the detection frame 13, and a rotating ring 18 rotatably connected to the upper part of the drilling member, specifically, the rotating ring 18 is rotatably connected to the connecting rod 14. In actual use, after the drilling position is determined, the walking mechanism drives the drilling mechanism to walk to the designated position, and then the detection frame 13 can be anchored on the ground. When anchoring, the detection frame 13 is in a vertically downward state, and the anchoring angle of the detection frame 13 can be controlled according to the existing technology for detecting the verticality.

[0030] In combination Figure 3 As shown, the detection frame 13 is vertically and slidably connected with a sliding rod 21, and the detection ring 20 is detachably connected to the sliding rod 21. Specifically, the detection frame 13 is provided with a cylinder for driving the sliding rod 21 to slide, and the sliding rod 21 and the detection ring 20 are bolted or clamped. The detection ring 20 is sleeved outside the upper part of the drilling member, specifically, the detection ring 20 is sleeved outside the connecting rod 14. In order to facilitate the detection ring 20 to be sleeved outside the drilling member, the detection ring 20 comprises two half rings which are detachably connected together and bolted after being sleeved outside the drilling member. A plurality of pressing rods 19 for pressing the detection ring 20 are fixed circumferentially on the rotating ring 18, that is, the detection ring 20 is installed below the pressing rods 19, and then the position of the sliding rod 21 is adjusted so that the pressing rods 19 are just pressed on the upper end of the detection ring 20. The pressing rods 19 are provided with pressure sensors, and the pressure sensors are selected from the sensors for detecting pressure signals in the prior art. When the detection frame 13 and the drilling frame 7 are both in a vertically downward state, the pressure signals detected by the pressure sensors on the plurality of pressing rods 19 are consistent, which can be used to assist the first level meter to control the angle adjustment of the drilling frame 7.

[0031] In addition, the detection ring 20 and the sliding rod 21 are detachably connected, so that the detection ring 20 with a suitable size can be selected according to the required hole diameter of the drilling, and after the drilling is completed, the detection ring 20 can be driven to extend into the drilled hole to detect whether the drilling meets the requirements. In order to adapt to detection rings 20 of different sizes, the pressing rods 19 are of telescopic structure, specifically, the pressing rods 19 are selected from conventional electric telescopic rods or other rods with telescopic function in the prior art.

[0032] In specific use, the drilling mechanism is brought to the designated position for drilling by walking of the walking mechanism. After reaching the designated position, the ground supporting rod 9 is deflected and telescoped, and the angle of the supporting plate 10 is adjusted so that the supporting plate 10 abuts against the ground at the tail end of the walking mechanism. Then the anchoring rod 11 is wedged into the ground so that the supporting plate 10 is fixed on the ground.

[0033] Then the detection frame 13 is anchored on the ground, and the detection frame 13 is in a vertical downward state during anchoring, and the angle of the detection frame 13 can be controlled according to the verticality detection mode of the prior art. Rotate the drilling frame 7, adjust the drilling frame 7 to be in a vertical downward state, and then the drilling member can drill vertically downward. The angle of the drilling frame 7 is detected by the first level meter, and it is judged whether the drilling frame 7 is deflected to a vertical downward state.

[0034] After adjusting the angle of the drilling frame 7, the detection ring 20 is assembled, the detection ring 20 is sleeved outside the drilling member, and the pressure rod 19 is pressed on the detection ring 20. When the detection frame 13 and the drilling frame 7 are in a vertical downward state, the pressure signals detected by the pressure sensors on the plurality of pressure rods 19 are consistent, which can be used to assist the first level meter to control the angle adjustment of the drilling frame 7.

[0035] During drilling, as the driving plate 12 slides downward, the sliding rod 21 is synchronously slid, so that the detection ring 20 moves downward synchronously with the drilling member. When the drilling member encounters hard objects (such as stones) in the soil, it may cause the drilling member to tilt and deflect or make it difficult for the drilling member to continue to move downward. When the drilling member tilts and deflects, the pressure of the plurality of pressure rods 19 on the detection ring 20 is no longer consistent, so that even if the drilling frame 7 does not actually deflect, it can be detected whether there is a problem in the drilling process. When the drilling member is difficult to continue to move downward, the sliding rod 21 continues to drive the detection ring 20 to move downward, and the pressure rod 19 is separated from the detection ring 20, so that there is no pressure signal, which can also remind the worker to intervene in time.

[0036] After drilling is completed, the drilling member is separated from the hole, and at this time the detection ring 20 can be driven to move downward into the hole, and the detection ring 20 of different sizes is used to detect whether the diameter of the drilled hole meets the requirements.

[0037] In another embodiment of the present application, in order to improve the grip of the walking mechanism on the slope, a gripping member is installed on the walking wheel 2. Specifically, the gripping member includes a mounting disc 3 rotatably connected to the side surface of the walking wheel 2, a motor for driving the mounting disc 3 to rotate is installed on the side surface of the walking wheel 2, a plurality of gripping knives 4 are hingedly connected to the mounting disc 3 along the circumferential direction thereof, a micro motor or motor for driving the gripping knives 4 to rotate is installed on the mounting disc 3, the gripping knives 4 are arc-shaped, and the arc-shaped trend of the gripping knives 4 is consistent with the rotating trend of the walking wheel 2. Then after the walking mechanism moves to the specified position, a plurality of gripping knives 4 can be synchronously driven to rotate, or only the gripping knives 4 located on the upper part of the mounting disc 3 at this time can be rotated, so that the gripping knives 4 extend away from the center of the mounting disc 3, and the knife tips of the gripping knives 4 protrude from the walking wheel 2. Then the mounting disc 3 is rotated, so that the gripping knives 4 can be rotated into the ground, thereby improving the grip.

[0038] In another embodiment of the present application, in order to facilitate the detection ring 20 to extend into the hole with different depths, the detection frame 13 is rotatably connected with the rotating shaft 16, the rotating shaft 16 is wrapped with the connecting rope 17, one end of the connecting rope 17 is fixed on the rotating shaft 16, and the other end of the connecting rope 17 is fixed on the detection ring 20. Specifically, the longitudinal section of the detection frame 13 is in the shape of inverted L, the rotating shaft 16 is arranged on the top of the detection frame 13, and the top of the detection frame 13 is higher than the driving plate 12. In order to ensure the levelness of the detection ring 20, the rotating shaft 16 is provided with at least three groups and is uniformly distributed along the circumference of the detection ring 20, and correspondingly, the multiple connecting ropes 17 pull or lower the detection ring 20 from multiple directions.

[0039] When detecting whether the drilled hole meets the requirements, the detection ring 20 and the sliding rod 21 can be disconnected, the multiple rotating shafts 16 are synchronously rotated, the connecting rope 17 is loosened, and then the detection ring 20 is lowered. When the hole diameter does not meet the requirements or when the verticality of the hole is problematic, the falling of the detection ring 20 will be affected, that is, hindered by the inner wall of the hole. The workers can detect the drilled hole by observing the falling smoothness of the detection ring 20 in the hole. The second level meter is installed on the detection ring 20, and the levelness of the detection ring 20 falling in the hole is detected by the second level meter, which assists in judging whether the falling of the detection ring 20 is affected.
