Description

Technical Field

[0001] The invention belongs to the technical field of mountain photovoltaic pile foundation engineering, and in particular relates to photovoltaic pile foundation drilling equipment used in mountains. Background Art

[0002] Mountain photovoltaic refers to photovoltaic power stations built in mountainous or hilly areas. Compared with photovoltaic power stations in plain areas, mountain photovoltaic power stations face more complex terrain and climatic conditions, but they also have unique advantages and characteristics such as higher power generation efficiency and less land occupation. The construction of photovoltaic power station pile foundation includes laying out measurement, foundation center positioning, drilling pile foundation holes, placing steel cages, installing formwork, placing embedded parts, pouring concrete, removing formwork, and maintenance.

[0003] Among them, drilling pile foundation holes refers to drilling holes in the ground with depth, size and verticality that meet the requirements through drilling equipment. However, since the construction of mountain photovoltaic power stations will be affected by terrain conditions, especially when construction is carried out on steep slopes, it is difficult to maintain stable construction when the drilling equipment is placed on the slope, and it is very easy to slip. It is also difficult to control the drill bit to drill in a vertical downward state. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a photovoltaic pile foundation drilling device for use in mountainous areas to solve the problem that when construction is carried out on a steep slope, it is difficult to maintain stable construction when the drilling equipment is placed on the slope surface, slippage is very likely to occur, and it is also difficult to control the drill bit to be in a vertical downward state for drilling.

[0005] According to an embodiment of the present invention, the present invention adopts the following technical solution:

[0006] Photovoltaic pile foundation drilling equipment for mountainous areas, comprising a walking mechanism and a drilling mechanism installed on the walking mechanism, the walking mechanism comprising a mounting plate and a walking wheel installed on the mounting plate, the tail end of the mounting plate being hinged with a retractable ground support rod; the drilling mechanism comprising a drill frame hinged on the mounting plate and a drilling member installed on the drill frame, a first level being installed on the top surface of the drill frame, and a limit member for limiting the angle of the drill frame being provided on the mounting plate; the drilling mechanism also comprises a detection component for detecting the verticality of the borehole, the detection component comprising a detection frame for anchoring on the ground, a detection ring installed on the detection frame, and a swivel rotatably connected to the upper part of the drilling member, a sliding rod being vertically slidably connected to the upper edge of the detection member, the detection ring being detachably connected to the sliding rod, the detection ring being sleeved on the outer side of the upper part of the drilling member, the detection ring comprising two half rings detachably connected together, a plurality of pressure rods for pressing the detection ring being circumferentially fixed to the upper edge of the swivel, and a pressure sensor being installed on the pressure rod.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. A deflectable and retractable ground support rod is installed at the tail end of the mounting plate. When the walking 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 walking mechanism, thereby increasing the friction force of the walking mechanism moving backward, preventing the walking mechanism from moving backward on the slope, and improving the stability of the drilling process of the drilling mechanism.

[0009] 2. Rotate the drill rack and adjust it to a vertical downward position so that the drilling member can drill vertically downward. Use the first level to detect the angle of the drill rack to determine whether the drill rack has deflected to a vertical downward position.

[0010] 3. Anchor the detection frame on the ground so that the detection frame is in a vertical downward position when anchored. After adjusting the angle of the drill frame, put the detection ring on the outside of the drilling part and press the pressure rod on the detection ring. When the detection frame and the drill frame are both in a vertical downward position, the pressure signals detected by the pressure sensors on the multiple pressure rods are consistent, which can be used to assist the first level to control the angle adjustment of the drill frame.

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

[0012] Furthermore, a gripping member is installed on the traveling wheel.

[0013] Furthermore, the gripping member includes a mounting plate rotatably connected to the side of the traveling wheel, and a plurality of gripping knives are hinged on the mounting plate along its circumference. The gripping knives are arc-shaped, and the arc trend of the gripping knives is consistent with the rotation trend of the traveling wheel.

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

[0015] Furthermore, a rotating shaft is rotatably connected to the detection frame, a connecting rope is wound around the outer side 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 detection ring.

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

[0017] Furthermore, the pressure rod is a telescopic structure.

[0018] Furthermore, the limiting member comprises a slide plate slidably connected to the mounting plate, a retractable limiting rod is hinged between the slide plate and the drill frame, and a driving rod for driving the slide plate to slide is installed on the mounting plate.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0024] like Figure 1 , Figure 2 As shown, the photovoltaic pile foundation drilling equipment for mountainous areas includes a traveling mechanism and a drilling mechanism installed on the traveling mechanism, the traveling mechanism includes a mounting plate 1 and a traveling wheel 2 installed on the mounting plate 1. In actual design, three or four traveling wheels 2 are selected, that is, the traveling mechanism is a three-wheeled trolley or a four-wheeled trolley, which is designed according to actual conditions. During actual use, a traction device (such as a winch) can be set at the front end of the mounting plate 1, and the mounting plate 1 can be moved by the traction device to 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 traveling mechanism on the slope.

[0025] The rear end of the mounting plate 1 is hinged with a retractable ground support rod 9, and the rear end refers to the rear end in the walking direction of the walking mechanism. Multiple ground support rods 9 can be provided to improve the limiting support effect. In this embodiment, the ground support rod 9 uses a conventional electric telescopic rod in the prior art. Through the extension and retraction of the ground support rod 9, it is convenient to adjust the position where the ground support rod 9 contacts and supports the ground. When the walking mechanism stops on the slope, the ground support rod 9 is deflected and extended, so that the ground support rod 9 abuts against the ground at the rear end of the walking mechanism, increasing the friction force of the walking mechanism retreating, preventing the walking 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 ground supporting rod 9, a supporting plate 10 is hinged at the end of the ground 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 the ground. The anchor rods 11 are bolted to the supporting plate 10. During actual use, when the anchor rods 11 are screwed into the supporting plate 10, the anchor rods 11 can be wedged into the ground, so that the supporting plate 10 is fixed to the ground, which has a better limiting effect on the walking mechanism.

[0027] The drilling mechanism includes a drilling frame 7 hinged on the mounting plate 1 and a drilling member mounted on the drilling frame 7. A first level is mounted on the top surface of the drilling frame 7. The first level is an instrument used in the prior art for detecting the levelness. The first level is mounted on the top surface of the drilling frame 7 (when the drilling frame 7 is in a vertical state, that is, Figure 2 ), the verticality of the drill frame 7 can be detected, and the drilling member can use the drill bit 15 of conventional drilling equipment in the prior art. In this embodiment, a design method is provided, the drilling member includes a driving plate 12 connected to the drill frame 7 along the axial sliding of the drill frame 7, the driving plate 12 is rotatably connected to the connecting rod 14, the connecting rod 14 is fixed with the drill bit 15, the drilling frame 7 is equipped with a cylinder for driving the driving plate 12 to slide, and the driving plate 12 is equipped with a motor for driving the connecting rod 14 to rotate, so that the drill bit 15 rotates while moving axially. In this embodiment, no improvement is made to how to drill holes and the drilling principle. The drill frame 7 is only used to adjust the angle of the drilling member. After the angle adjustment is completed, other conventional drilling methods in the prior art can also be used for drilling.

[0028] A motor for driving the drill rig 7 to rotate is installed on the mounting plate 1, and a limiting member for limiting the angle of the drill rig 7 is also provided on the mounting plate 1. Specifically, the limiting member includes a slide plate 5 slidably connected to the mounting plate 1, and a retractable limiting rod 6 is hinged between the slide plate 5 and the drill rig 7. The limiting rod 6 uses an electric telescopic rod in the prior art, and a driving rod 8 for driving the slide plate 5 to slide is installed on the mounting plate 1. Specifically, a cylinder for driving the driving rod 8 to slide is also installed on the mounting plate 1. In the process of adjusting the angle of the drill rig 7 by the motor, the telescopic length of the limiting rod 6 and the sliding position of the slide plate 5 are synchronously adjusted, so that the limiting rod 6 and the slide plate 5 are both adapted to the angle of the drill rig 7. After the angle of the drill rig 7 is adjusted, the telescopic length of the limiting rod 6 and the sliding position of the slide plate 5 remain stationary, so that a stable triangle shape is formed between the limiting rod 6, the drill rig 7 and the mounting plate 1, and the limiting rod 6 supports and limits the drill rig 7.

[0029] The drilling mechanism also includes a detection assembly for detecting the verticality of the drilling, which includes a detection frame 13 for anchoring on the ground, a detection ring 20 installed on the detection frame 13, and a swivel 18 rotatably connected to the upper part of the drilling member. Specifically, the swivel 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 specified position, and then the detection frame 13 can be anchored on the ground. When anchoring, the detection frame 13 is in a vertical downward state, and the anchoring angle of the detection frame 13 can be controlled according to the method of detecting verticality in the prior art.

[0030] Combination Figure 3 As shown, a slide bar 21 is vertically slidably connected to the detection frame 13, and a detection ring 20 is detachably connected to the slide bar 21. Specifically, a cylinder for driving the slide bar 21 to slide is installed on the detection frame 13, and the slide bar 21 and the detection ring 20 are bolted or clamped. The detection ring 20 is sleeved on the outer side of the upper part of the drilling member, specifically, the detection ring 20 is sleeved on the outer side of the connecting rod 14. In order to facilitate the detection ring 20 to be sleeved on the outer side of the drilling member, the detection ring 20 includes two half rings that are detachably connected together, and the two half rings are sleeved on the outer side of the drilling member and then bolted. A plurality of pressure rods 19 for pressing the detection ring 20 are fixed along the circumference of the swivel ring 18, that is, the detection ring 20 is installed under the pressure rod 19, and then the position of the slide bar 21 is adjusted so that the pressure rod 19 is just pressed on the upper end of the detection ring 20. A pressure sensor is installed on the pressure rod 19. The pressure sensor uses a sensor used in the prior art for detecting pressure signals. When the detection frame 13 and the drill frame 7 are both in a vertical downward state, the pressure signals detected by the pressure sensors on the multiple pressure rods 19 are consistent, which can be used to assist the first level to control the angle adjustment of the drill frame 7.

[0031] In addition, the detection ring 20 and the slide bar 21 are detachably connected, so the detection ring 20 of the appropriate size can be selected according to the required hole diameter. After the drilling is completed, the detection ring 20 can be driven into the drilled hole to detect whether the drilling meets the requirements. In order to adapt to detection rings 20 of different sizes, the pressure rod 19 is a telescopic structure. Specifically, the pressure rod 19 uses a conventional electric telescopic rod or other rod body with telescopic function in the prior art.

[0032] During specific use, the drilling mechanism is brought to the designated position for drilling by the movement of the walking mechanism. After reaching the designated position, the ground support rod 9 is deflected and extended, and the angle of the support plate 10 is adjusted so that the support plate 10 is in contact with the ground at the tail end of the walking mechanism, and then the anchor rod 11 is wedged into the ground so that the support plate 10 is fixed to the ground.

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

[0034] After adjusting the angle of the drill rig 7, assemble the detection ring 20, and put the detection ring 20 on the outside of the drilling member, and make the pressure rod 19 press on the detection ring 20. When the detection frame 13 and the drill rig 7 are both in a vertical downward state, the pressure signals detected by the pressure sensors on the multiple pressure rods 19 are consistent, which can be used to assist the first level to control the angle adjustment of the drill rig 7.

[0035] During the drilling process, as the driving plate 12 slides down, the sliding rod 21 slides synchronously, so that the detection ring 20 moves downward synchronously with the drilling member. When the drilling member encounters a hard object (such as a stone) in the soil, it may cause the drilling member to tilt or deflect, or it may be difficult for the drilling member to continue to move downward. When the drilling member tilts or deflects, the pressure of multiple pressure rods 19 on the detection ring 20 is no longer consistent. Even if the drilling frame 7 does not actually deflect in the end, it can be used to detect 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, and there is no pressure signal, which can also remind the staff to intervene in time.

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

[0037] In another embodiment of the present invention, in order to improve the gripping force of the walking mechanism on the slope, a gripping member is installed on the walking wheel 2. Specifically, the gripping member includes a mounting plate 3 rotatably connected to the side of the walking wheel 2, a motor for driving the mounting plate 3 to rotate is installed on the side of the walking wheel 2, and a plurality of gripping knives 4 are hinged on the mounting plate 3 along its circumference. A micro motor or motor for driving the gripping knives 4 to rotate is installed on the mounting plate 3. The gripping knives 4 are arc-shaped, and the arc-shaped trend of the gripping knives 4 is consistent with the rotation trend of the walking wheel 2. After the walking mechanism moves to the specified position, multiple gripping knives 4 can be driven to rotate synchronously, or only the gripping knives 4 located on the upper part of the mounting plate 3 can be rotated so that the gripping knives 4 extend in a direction away from the center of the mounting plate 3, and the tip of the gripping knives 4 protrudes from the walking wheel 2. Then the mounting plate 3 is rotated so that the gripping knives 4 can be screwed into the ground to improve the gripping force.

[0038] In another embodiment of the present invention, in order to facilitate the detection ring 20 to extend into holes of different depths, a rotating shaft 16 is rotatably connected to the detection frame 13, a connecting rope 17 is wound around the outer side of the rotating shaft 16, one end of the connecting rope 17 is fixed to the rotating shaft 16, and the other end of the connecting rope 17 is fixed to the detection ring 20. Specifically, the longitudinal section of the detection frame 13 is an inverted L-shape, and the rotating shafts 16 are all arranged at 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 horizontality of the detection ring 20, at least three groups of rotating shafts 16 are provided and are evenly distributed along the circumference of the detection ring 20. Accordingly, multiple groups of connecting ropes 17 are used to lift or lower the detection ring 20 from multiple directions.

[0039] When checking whether the drilled hole meets the requirements, the connection between the detection ring 20 and the slide bar 21 can be released, and the detection ring 20 can be lowered by synchronously rotating multiple sets of rotating shafts 16 and loosening the connecting rope 17. The detection ring 20 naturally falls in the hole. When the hole diameter does not meet the requirements, or when there is a problem with the verticality of the hole, the fall of the detection ring 20 will be affected, that is, it will be hindered by the inner wall of the hole. The staff can detect the drilled hole by observing the smoothness of the fall of the detection ring 20 in the hole. A second level is installed on the detection ring 20, and the second level is used to detect the horizontality of the detection ring 20 falling in the hole to assist in judging whether the fall of the detection ring 20 is affected.
