Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction auxiliary equipment technology, and in particular to a hole-forming device for photovoltaic construction. Background Technology

[0002] When constructing a photovoltaic power station, it is necessary to drill holes for pile foundations and then pour concrete to form piles. Before pouring concrete, the bottom of the holes needs to be cleaned.

[0003] Currently, construction sites use specialized cleaning tools to clean the bottom of holes. For example, Chinese utility model patent application number 2021231780518 provides a special hole cleaning device for photovoltaic support foundations. It includes a main shaft, a rotary drilling rig at one end of the main shaft, and a handle at the other end of the main shaft. In use, the rotary drilling rig is inserted into the bottom of the hole, and then the main shaft is rotated by the handle or with the help of a wrench or other tools to drive the rotary drilling rig to clean the hole. This method is more efficient than the traditional hole cleaning method using a Luoyang shovel or similar tools.

[0004] However, in actual use, since the bottom of the hole is mostly loose soil when cleaning the hole, the rotary excavator rotates to excavate the loose soil to the top of the excavator, and then pulls the main shaft to pull the excavator out of the hole. During the pulling process, since the diameter of the excavator is matched with the hole diameter, the loose soil will not fall off in large quantities. However, when leaving the hole opening, the loose soil is easy to fall off the excavator again into the hole, affecting the cleaning effect. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a hole-forming device for photovoltaic construction.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a hole-forming device for photovoltaic construction, comprising a rod, a handle, and a rotary drilling rig, and further comprising:

[0007] The casing is movably sleeved on the rod body and has a first limiting surface facing the rotary drilling rig. It is located between the rotary drilling rig and the first limiting surface. A second limiting surface facing the first limiting surface is provided on the rod body.

[0008] The elastic element is positioned between the rod and the casing;

[0009] A handle, installed on the grip;

[0010] The pull rope is connected to the handle and the protective sleeve at both ends.

[0011] Furthermore, on the side of the casing away from the rotary excavator, a limiting component is also provided on the rod body. The retaining elastic component is a compression spring sleeved on the rod body, with both ends of the compression spring abutting against the limiting component and the casing, respectively.

[0012] Furthermore, both the limiting component and the handle are movably sleeved with the rod body.

[0013] Furthermore, the handle includes a first movable sleeve slidably sleeved on the rod body and two handles disposed on the first movable sleeve. A locking screw is threadedly connected to the first movable sleeve, and a plurality of first positioning holes for the locking screw to pass through are provided at intervals on the rod body.

[0014] Furthermore, it also includes a rigid plate, and the handle is provided with a guide rod connected to the rigid plate, and the handle is provided with a guide sleeve that slides and cooperates with the guide rod.

[0015] Furthermore, guide rods are provided at both ends of the rigid plate, and the guide rods are arranged parallel to the rod body.

[0016] Furthermore, a conduit is sleeved around the pull rope, and positioning sleeves are provided on both the rigid plate and the limiting member, with both ends of the conduit abutting against the two positioning sleeves.

[0017] Compared with the prior art, the hole-forming device for photovoltaic construction disclosed in this utility model has the following advantages: the elastic element can provide elastic force to the casing in the direction of the rotary excavator, and the casing can be kept in working state by the elastic force. At this time, the lower end of the casing is partially overlapped with the rotary excavator. When the handle is held and the rod is rotated to drive the rotary excavator to remove soil from the bottom of the hole for cleaning, the soil excavated by the rotary excavator will be excavated to the top of the rotary excavator. At this time, the casing can resist the soil. When the rotary excavator is taken out of the hole, the probability of soil falling again can be effectively reduced, and a better hole cleaning effect can be achieved. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] Please refer to Figure 1-3 As a specific implementation, this application provides a hole-forming device for photovoltaic construction, including a rod body 5, a handle 1, and a rotary drilling rig 4. It also includes: a protective sleeve 41, which is movably sleeved on the rod body 5 and has a first limiting surface 411 facing the rotary drilling rig 4, located between the rotary drilling rig 4 and the first limiting surface 411; a second limiting surface 52 facing the first limiting surface 411 on the rod body 5; a retaining elastic element 42, which is disposed between the rod body 5 and the protective sleeve 41; a handle 6, which is disposed on the handle 1; and a pull rope 71, with both ends connected to the handle 6 and the protective sleeve 41, respectively.

[0029] Specifically, it should be noted that the rod 5 provided in this application is a metal tube with a rectangular cross-section, and a auger soil extractor is installed at the lower end. A handle 1 is installed on the rod 5. (Refer to...) Figure 7 , Figure 8This application slidably mounts a protective sleeve 41 on the rod body 5. The protective sleeve 41 includes a second movable sleeve 410 that slides and guides the rod body 5. The end face of the second movable sleeve 410 is the first limiting surface 411. The rod body 5 is provided with a stepped portion, the stepped surface of which is the second limiting surface 52. It also includes a retaining elastic member 42 disposed between the rod body 5 and the protective sleeve 41. The retaining elastic member 42 can provide elastic force to the protective sleeve 41 in the direction of the rotary excavator 4. Through this elastic force, the protective sleeve 41 can be held in place. Figure 7 The first limiting surface 411 shown is in the working state where it abuts against the second limiting surface 52. At this time, the lower end of the casing 41 partially overlaps with the rotary excavator 4. When the handle 1 is held and the rod 5 is rotated to drive the rotary excavator 4 to remove soil from the bottom of the hole for cleaning, the soil excavated by the rotary excavator 4 will be excavated to the top of the rotary excavator 4. At this time, the casing 41 can block the soil. When the rotary excavator 4 is removed from the hole, the probability of soil falling again can be effectively reduced, and a better hole cleaning effect can be achieved. After the rotary excavator 4 is removed, the handle 6 is pulled manually. The handle 6 pulls the casing 41 against the elastic force of the retaining elastic element 42 to move upward through the pull rope 71. (Refer to...) Figure 8 At this point, the bottom of the casing 41 leaves the rotary excavator 4, and the soil above the rotary excavator 4 can fall off. After falling off, the handle 6 is released, and the casing 41 returns to the working state under the elastic force of the elastic element 42.

[0030] Furthermore, as a specific implementation method, the pull rope 71 is made of steel wire rope.

[0031] Furthermore, as a specific implementation, a limiting member 43 is also provided on the side of the casing 41 away from the rotary excavator 4. The retaining elastic member 42 is a compression spring sleeved on the rod 5, and the two ends of the compression spring abut against the limiting member 43 and the casing 41 respectively.

[0032] For details, please refer to Figure 4 , Figure 7 In one implementation, the specific structure of the limiting member 43 is as follows: it includes a third movable sleeve 430 that slides and guides the rod body 5, and a limiting plate 431 that is welded to the third movable sleeve 430; along the direction perpendicular to the axis of the rod body 5, the third movable sleeve 430 is provided with through holes on opposite side walls, and a through hole adapted to the through hole is drilled on the rod body 5, so that a fixing screw can pass through the through hole and the through hole, and a nut is threadedly connected to the end of the fixing screw that passes through the rod body 5 and the third movable sleeve 430, thereby fixing the third movable sleeve 430 to the rod body 5. The retaining elastic member 42 is a compression spring sleeved on the rod body 5. With this arrangement, the overall structure is reasonable, and it is easy to disassemble the limiting member 43 from the rod body 5, thereby facilitating the disassembly and installation of the protective sleeve 41 and facilitating later maintenance.

[0033] Furthermore, as a specific implementation, both the limiting member 43 and the handle 1 are movably sleeved with the rod body 5. Specifically, as a preferred implementation, both the limiting member 43 and the handle 1 are movably sleeved with the rod body 5. This movable sleeved engagement facilitates the disassembly of the handle 1 and the limiting member 43 from the rod body 5, thereby facilitating the disassembly of the protective sleeve 41 and aiding in maintenance. Furthermore, as a specific implementation, refer to... Figure 5 , Figure 6 The specific structure of the handle 1 is as follows: the handle 1 includes a first movable sleeve 10 that is slidably sleeved on the rod body 5 and two handles 13 that are provided on the first movable sleeve 10. A locking screw 12 is threadedly connected to the first movable sleeve 10. A plurality of first positioning holes 51 for the locking screw 12 to pass through are provided at intervals on the rod body 5. Specifically, the handle 1 includes a first movable sleeve 10 and two handle rods 13 welded to opposite sides of the first movable sleeve 10. The handle rods 13 are metal tubular fittings. A guide rod 61 is welded to the side of the handle rod 13 near the rotary excavator 4. A rigid plate 60 is detachably connected to the end of the guide rod 61. Multiple first positioning holes 51 are drilled at intervals along the length of the rod body 5. A first threaded sleeve 11 is welded to the first movable sleeve 10. In actual use, a second through hole is provided on the side wall of the first movable sleeve 10 for the screw to pass through. Then, the first threaded sleeve 11 is welded to the first movable sleeve 10 corresponding to the second through hole. The first threaded sleeve 11 is a metal sleeve with internal threads on its inner side wall, which can be threadedly connected to the screw. With this arrangement, the screw can be threadedly connected to the first threaded sleeve 11 and then the end can be inserted into the first positioning hole 51 to position the first threaded sleeve 11, thereby fixing the handle 1 and facilitating the disassembly and installation of the handle 1.

[0034] Furthermore, as a specific implementation method, refer to Figure 5 , Figure 6 It also includes a rigid plate 60. The handle 13 is provided with a guide rod 61 connected to the rigid plate 60, and the handle 1 is provided with a guide sleeve 62 that slides and guides the guide rod 61. Specifically, two guide rods 61 are welded on each handle 13. The lower end of the guide rod 61 is machined with a stepped shaft, and the outer circumferential surface of the stepped shaft is machined to form an external thread. Both ends of each rigid plate 60 are provided with through holes for the stepped shaft to pass through. After the stepped shaft passes through the through holes, a locking nut is threadedly connected, so that the rigid plate 60 and the guide rod 61 are detachably and fixedly connected. Both ends of the handle 6 are provided with guide sleeves 62 that guide and cooperate with the guide rod 61. The middle area of ​​the rigid plate 60 is provided with a through hole for the pull rope 71 to pass through. With this arrangement, one end of the pull rope 71 is connected to the protective sleeve 41, and the other end passes through the rigid plate 60 and is connected to the handle 6, so that the protective sleeve 41 can be driven to move against the retaining elastic element 42 by pulling the handle 6.

[0035] As another implementation, the rigid plate 60 can also be fixedly connected to the guide rod 61 by welding.

[0036] Furthermore, as a preferred embodiment, guide rods 61 are provided at both ends of the rigid plate 60, and the guide rods 61 are arranged parallel to the rod body 5. Specifically, by providing two guide rods 61, a better guiding effect can be provided for the handle 6, making it easier to operate.

[0037] Furthermore, as a specific implementation method, refer to Figures 1-6 The pull rope 71 is externally sleeved with a conduit 7, and both the rigid plate 60 and the limiting member 43 are provided with positioning sleeves 72. The two ends of the conduit 7 abut against the two positioning sleeves 72. Specifically, the pull rope 71 of this application is externally sleeved with a conduit 7, wherein the pull rope 71 and the conduit 7 are existing brake cables in the prior art, wherein the conduit 7 is incompressible in the length direction, the pull rope 71 is made of steel wire rope, and positioning sleeves 72 are threadedly connected to the through hole on the rigid plate 60. (Refer to...) Figure 4 A second threaded sleeve 432 is provided on the third movable sleeve 430 of the limiting member 43. The second threaded sleeve 432 is threadedly connected to the positioning sleeve 72. The two ends of the conduit 7 abut against the two positioning sleeves 72. The pull rope 71 passes through the positioning sleeve 72, the conduit 7 and the positioning sleeve 72 in sequence, and then the two ends are connected to the handle 6 and the protective sleeve 41. With this setting, the position of the handle 1 can be adjusted according to the hole depth, which is convenient for adjustment and thus more convenient to use.

[0038] Furthermore, as a preferred embodiment, the pull rope 71 is provided in two sets, symmetrically arranged about the rod body 5. With this arrangement, a handle 6 can be provided on each of the two handles 13 of the handle 1, allowing for simultaneous operation with both hands and ensuring balanced force applied to the protective cylinder 41.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
