Technical Field

[0001] This utility model relates to the technical field of grounding wire installation and retrieval tools for oil drilling, and in particular to an auxiliary device suitable for installing and retrieving grounding wire poles. Background Technology

[0002] In the oil drilling industry, electrical equipment and mobile shelters all need to be connected to ground wires to ensure normal operation. Oil drilling sites require a large number of grounding poles. Whenever a new well is moved for installation, all grounding poles for the electrical equipment need to be driven into the ground. This requires a lot of personnel, is physically demanding, is difficult to control the direction, poses safety risks, and has low construction efficiency. After the well is completed, all grounding poles need to be removed. Because the grounding poles have been buried underground for a long time, they are difficult to pull out, resulting in a large amount of on-site work that is time-consuming and labor-intensive.

[0003] Therefore, how to provide an auxiliary device suitable for the installation and removal of grounding poles to improve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for installing and removing grounding poles, eliminating the need for brute force in pulling out grounding poles, saving time and effort, reducing the labor intensity of employees, and improving work efficiency.

[0005] To achieve the above objectives, this utility model provides an auxiliary device suitable for installing and removing grounding poles, including a pulling device. The pulling device includes a support frame, a rotating arm, a movable part, and a clamping part. The rotating arm includes a first end, a second end, and a rotating arm body located between the first end and the second end. The rotating arm body is hinged to the top of the support frame, such that when the second end is pressed down relative to the support frame, the first end is raised relative to the support frame. The top of the movable part is hinged to the first end, and the bottom of the movable part is hinged to the clamping part. The clamping part has a slot for engaging with the outer periphery of the grounding pole, so that when the first end moves the movable part upward, the clamping part moves the grounding pole upward.

[0006] In one possible implementation, the support frame includes a chassis and a support member. One end of the support member is vertically connected to the chassis, and the other end of the support member is provided with a first mounting position. The first mounting position is provided with a first mounting hole. The rotating arm body is provided with a second mounting hole. A first pin passes through the first mounting hole and the second mounting hole, so that the rotating arm and the support frame can rotate relative to each other around the axis of the first pin.

[0007] In one possible implementation, the angle formed by the line connecting the center of the first end and the axis of the first pin and the line connecting the center of the second end and the axis of the first pin is 120°-170°.

[0008] In one possible implementation, the top of the movable part is provided with a third mounting hole, the first end is provided with a fourth mounting hole, and the second pin passes through the third mounting hole and the fourth mounting hole, so that the movable part and the first end can rotate relative to each other about the axis of the second pin.

[0009] In one possible implementation, the bottom of the movable part is provided with a first pin hole parallel to the axis of the third mounting hole, the clamping part is provided with a second pin hole corresponding to the first pin hole, and the third pin passes through the first pin hole and the second pin hole, so that the movable part and the clamping part can rotate relative to each other about the axis of the third pin.

[0010] In one possible implementation, the opening of the slot is oriented parallel to the axial direction of the third pin.

[0011] In one possible implementation, the inner wall of the slot is provided with an abutment surface, which is an arc surface and is used to abut against the outer periphery of the grounding wire rod.

[0012] In one possible implementation, the extraction device further includes an extension rod, one end of which is provided with a plurality of first fixing holes and the second end is provided with a plurality of second fixing holes. The extension rod is movably connected to the second end, and when the connector passes through the corresponding first fixing hole and second fixing hole, the extension rod is fixed relative to the second end.

[0013] In one possible implementation, a center rod is also included, comprising a first connecting section and a second connecting section located at both ends of the center rod. The first connecting section is connected to a helical impeller, and the second connecting section is used to connect to a rotational power source to drive the center rod to rotate the helical impeller for drilling, so as to allow the grounding wire rod to be installed in the ground.

[0014] In one possible implementation, a handle is attached to one end of the second connecting segment near the first connecting segment, and the handle is perpendicular to the extension direction of the central rod.

[0015] Compared to the aforementioned background technology, the auxiliary device for installing and removing grounding poles provided by this utility model includes a pulling device. The pulling device includes a support frame, a rotating arm, a movable part, and a clamping part. The rotating arm includes a first end, a second end, and a rotating arm body located between the first end and the second end.

The top of the movable part is hinged to the first end, and the bottom of the movable part is hinged to the clamping part. The clamping part has a slot for engaging with the outer periphery of the grounding pole, so that when the first end moves the movable part upward, the clamping part moves the grounding pole upward.

[0016] Specifically, after the support frame is placed stably on the ground, the slot in the clamping component is engaged with the preset position on the outer periphery of the grounding rod. By moving the second end downward, the first end of the rotating arm rotates upward around the hinge position between the rotating arm and the support frame. The movable part rotates around the hinge position with the first end and is driven to rise vertically, thereby causing the clamping component, which is hinged to the bottom of the movable part, to clamp the grounding rod and move the grounding rod upward synchronously. Then, the position of the second end is moved so that the clamping component falls down to contact the preset position below the grounding rod. The process of moving the second end downward is repeated to pull out the grounding rod buried in the ground. This eliminates the need for brute force to pull out the grounding rod, saving time and effort, reducing the labor intensity of employees, and improving work efficiency. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0037] The purpose of this invention is to provide an auxiliary device for installing and removing grounding poles, eliminating the need for brute force in pulling out grounding poles, saving time and effort, reducing the labor intensity of employees, and improving work efficiency.

[0038] Please see Figure 1 and Figure 3To achieve the above objectives, this utility model provides an auxiliary device suitable for installing and removing grounding poles, including a pulling device. The pulling device includes a support frame 100, a rotating arm 200, a movable member 300, and a clamping member 400. The rotating arm 200 includes a first end 210, a second end 220, and a rotating arm 200 body located between the first end 210 and the second end 220. The rotating arm 200 body is hinged to the top of the support frame 100, such that when the second end 220 is pressed down relative to the support frame 100, the first end 210 is raised relative to the support frame 100. The top of the movable member 300 is hinged to the first end 210, and the bottom of the movable member 300 is hinged to the clamping member 400. The clamping member 400 is provided with a slot 410, which is used to cooperate with the outer periphery of the grounding pole, so that when the first end 210 drives the movable member 300 to move upward, the clamping member 400 drives the grounding pole to move upward.

[0039] After the support frame 100 is placed stably on the ground, the slot 410 in the clamping member 400 is engaged with a preset position on the outer periphery of the grounding rod. The preset position refers to the position when the slot 410 in the clamping member 400 is initially engaged with the grounding rod, usually the top of the grounding rod. The support frame 100 provides a fulcrum for the rotation of the rotating arm 200. By moving the second end 220 downward, the first end 210 of the rotating arm 200 rotates upward about the hinge position between the rotating arm 200 and the support frame 100. The movable part 300... The device rotates around the hinged position of the first end 210 and is driven to rise vertically, thereby causing the clamping member 400, which is hinged to the bottom of the movable member 300, to clamp the grounding rod and drive the grounding rod to move upward synchronously. Then, the position of the second end 220 is moved so that the clamping member 400 falls down to contact the grounding rod at a preset position. The process of the second end 220 moving downward is repeated to pull out the grounding rod buried in the ground. This eliminates the need for brute force to pull out the grounding rod, saving time and effort, reducing the labor intensity of employees, and improving work efficiency.

[0040] It should be noted that the slot 410 has a large opening to allow the exposed portion of the grounding rod to enter the slot 410. The end of the clamping member 400 connected to the movable member 300, the movable member 300, the support frame 100, and the rotating arm 200 are all located on the same side of the grounding rod. When the clamping member 400 rotates relative to the movable member 300 to a horizontal or near-horizontal state, the grounding rod easily enters the slot 410. Then, under its own weight, the clamping member 400 rotates relative to the bottom of the movable member 300. The contact between the inner wall of the clamping member 400 and the grounding rod restricts further rotation, causing the clamping member 400 to tilt to the left, lower than the right. The left end refers to the clamping member 400... The right end refers to the end of the clamping member 400 connected to the movable member 300. When the movable member 300 moves upward, the right end of the clamping member 400 is lifted, so that the clamping member 400 clamps the grounding rod and drives the grounding rod to move upward synchronously. Then, by shaking the support frame 100, the clamping member 400 can be rotated relative to the bottom of the movable member 300 to a non-clamped state with the grounding rod. The clamping member 400 is moved to the slot 410 and contacts the lower part of the grounding rod. By repeating the above process, the grounding rod can be moved upward again. That is, by using the designed lever principle, the grounding rod is lifted out of the ground section by section by repeatedly lifting and pressing the second end 220. After it is taken out, the hole is filled with soil and compacted.

[0041] In one possible implementation, the support frame 100 includes a chassis 110 and a support member 120. The chassis 110 may be a plate-like structure, and the specific shape of the plate-like structure can be set according to actual needs. It may be, but is not limited to, circular or square, and has a certain surface area for contact with the ground to reduce the pressure on the ground. One end of the support member 120 is vertically connected to the chassis 110, and the other end of the support member 120 is provided with a first mounting position. The first mounting position is provided with a first mounting hole. Specifically, the first mounting position includes two spaced and parallel first plates. The two first plates are provided with axially aligned first mounting holes. The rotating arm 200 body is provided with a second mounting hole. The first pin 500 passes through the first mounting hole and the second mounting hole and is axially limited by a first limiting member so that the rotating arm 200 and the support frame 100 can rotate relative to each other around the axis of the first pin 500.

[0042] In one possible implementation, the angle formed by the line connecting the center of the first end 210 and the axis of the first pin 500 and the line connecting the center of the second end 220 and the axis of the first pin 500 is 120°-170°. When the first end 210 and the first pin 500 are at the same height, the second end 220 is at a higher height than the first pin 500, so that the operator can hold the second end 220 to perform subsequent pressing actions. The rotating arm 200 can adopt an integral structure to ensure the overall structural strength of the rotating arm 200.

[0043] In one possible implementation, the top of the movable member 300 is provided with a third mounting hole. Specifically, the top of the movable member 300 is provided with two spaced and parallel second plates, and the two second plates are provided with third mounting holes with collinear axes. The first end 210 is provided with a fourth mounting hole. The second pin 600 passes through the third mounting hole and the fourth mounting hole and is axially limited by the second limiting member, so that the movable member 300 and the first end 210 can rotate relative to each other around the axis of the second pin 600.

[0044] In one possible implementation, the bottom of the movable member 300 is provided with a first pin hole parallel to the axis of the third mounting hole, and the clamping member 400 is provided with a second pin hole corresponding to the first pin hole. Specifically, one side of the clamping member 400 is provided with two parallel and spaced third plates, and the two third plates are provided with second pin holes with collinear axes. The third pin passes through the first pin hole and the second pin hole and is axially limited by a third limiting member so that the movable member 300 and the clamping member 400 can rotate relative to each other around the axis of the third pin.

[0045] It should be noted that the axes of the first pin 500, the second pin 600 and the third pin are parallel to each other and are all parallel to the plane of the chassis 110, so that the rotating arm 200, the movable part 300 and the clamping part 400 can all rotate in the vertical plane, and complete the upward or downward movement of the movable part 300 and the clamping part 400 in the vertical plane.

[0046] Please see Figure 4 In one possible implementation, the opening of the slot 410 is parallel to the axial direction of the third pin, that is, the opening of the slot 410 is located between the left and right ends of the clamping member 400, so that when the clamping member 400 moves horizontally, the grounding rod fixed relative to the ground can enter the slot 410. When the clamping member 400 is tilted relative to the horizontal plane under its own weight, the inner wall of the slot 410 near the left end of the clamping member 400 can contact the lower outer side of the grounding rod, and the inner wall of the slot 410 near the right end of the clamping member 400 can contact the upper outer side of the grounding rod, so that the slot 410 can clamp the grounding rod during the subsequent lifting of the movable member 300.

[0047] Furthermore, the inner wall of the slot 410 is provided with an abutment surface 420. The abutment surface 420 is provided on two inner walls of the slot 410 for contacting the grounding rod. The abutment surface 420 can be, but is not limited to, the inner wall of the slot 410 near the left end of the clamping member 400 and the inner wall near the right end of the clamping member 400. The grounding rod is usually a rod-shaped structure. The abutment surface 420 is set as an arc surface. The arc surface increases the contact area between the inner wall of the slot 410 and the grounding rod. The abutment surface 420 is used to abut against the outer periphery of the grounding rod. Then, using the principle of a pry bar, the grounding rod can be easily pulled out of the ground.

[0048] Please see Figure 2 In one possible implementation, the extraction device further includes an extension rod 700. One end of the extension rod 700 is provided with a plurality of first fixing holes, and the second end 220 is provided with a plurality of second fixing holes 221. The extension rod 700 is movably connected to the second end 220, and when the connector 800 passes through the corresponding first fixing hole and second fixing hole 221, the extension rod 700 is fixed relative to the second end 220. The number of first fixing holes and second fixing holes 221 can both be set to five. The first fixing holes and second fixing holes 221 can be, but are not limited to, threaded holes, and the connector 800 can be, but is not limited to, a wing bolt.

[0049] The first fixing holes are sequentially arranged along the extension direction of the extension rod 700, and the second fixing holes 221 are sequentially arranged along the extension direction of the second end 220. The second end 220 can be set as a hollow tube. The diameter of the extension rod 700 is smaller than the inner wall diameter of the hollow tube, so that the extension rod 700 can be inserted into the second end 220 and move telescopically relative to the second end 220. When the extension rod 700 moves to the preset extension length, the connector 800 can be inserted through the corresponding first fixing hole and second fixing hole 221 to fix the extension rod 700 relative to the second end 220, thereby limiting the relative movement of the extension rod 700 and the second end 220. When it is necessary to readjust the extension length of the extension rod 700, the connector 800 can be disassembled or loosened, and then reinstalled or tightened after readjustment.

[0050] Please see Figure 5 and Figure 6In one possible implementation, the auxiliary device for retrieving the grounding pole further includes a drilling device. The drilling device includes a central rod 900, which can be housed in two cavities within the same housing for storing the extraction device and the drilling device. The central rod 900 includes a first connecting section and a second connecting section 920, located at both ends of the central rod 900. The first connecting section is connected to a helical impeller 910. The outer diameter of the projected area of ​​the helical impeller 910 along the axial direction of the central rod 900 can be set according to the drilling requirements. For example, the helical impeller... The outer diameter of the projected area of ​​910 along the axial direction of the central rod 900 can be set to 50mm. The second connecting section 920 is used to connect to the rotary power source. The rotary power source can be, but is not limited to, a drilling tool, such as an electric drill or a pneumatic drill. It is connected to the rotary power source through the second connecting section 920 and rotates under the drive of the rotary power source, thereby causing the central rod 900 to drive the spiral impeller 910 to rotate to drill a hole. The rotational power of the power part is converted into a downward drilling force to realize the drilling of the ground. After the drilling reaches the preset depth, it is used to install the grounding rod into the ground.

[0051] In one possible implementation, a handle 930 is connected to one end of the second connecting section 920 near the first connecting section. The handle 930 is perpendicular to the extension direction of the central rod 900. It is used to lift the drilling device out of the hole by holding the handle 930 after the spiral impeller 910 has been screwed into the ground to a certain depth, and at the same time, the spiral impeller 910 carries the drilled sand out of the hole.

[0052] It should be noted that the drilling depth can be adjusted according to the required burial depth of the grounding rod. For example, when the length of the grounding rod is greater than or equal to 1.5m and the burial depth is not less than 1.0m, the drilling depth should be at least 1.0m. If the length of the center rod 900 is less than 1.0m (e.g., 30cm), an extension rod can be installed. The first end of the extension rod is connected to the second connecting section 920, and the second end of the extension rod is connected to the rotary power source. This allows the center rod 900 to continue drilling to the required burial depth after drilling a hole about 30cm deep, through the extension rod. The projection of the handle 930 along the axial direction of the center rod 900 should be covered by the projection of the spiral impeller 910 along the axial direction of the center rod 900 to avoid affecting the drilling process. During drilling, water can be continuously poured into the hole to facilitate the drilling process.

[0053] When installing or removing grounding poles on site, the use of this auxiliary device for installing and removing grounding poles enables the installation and removal of grounding poles to be completed quickly on the construction site, extending the service life of the grounding poles. Both tasks can be easily completed by one person, which not only improves construction efficiency but also reduces safety risks and physical exertion, and has great potential for widespread application.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
