Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a grounding device and construction equipment. Background Art

[0002] As the degree of mechanization in the construction industry continues to increase, more and more construction machinery requires electric drive to operate. In order to improve the safety of motor-driven construction machinery, the machinery is usually grounded through a grounding device.

[0003] In the related art, a retractable grounding rod is proposed to improve the safety of workers, such as the patent application with publication number "CN214280230U". The retractable grounding rod can only be extended to a fixed length, resulting in limited applicable scenarios. It is necessary to produce grounding rods of different lengths for different construction scenarios, which is costly. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the utility model provides a grounding device.

[0006] A second aspect of the utility model provides a construction device.

[0007] In view of this, according to the first aspect of the utility model, a grounding device is proposed, which is characterized in that it is applied to construction equipment and includes: an insulating shell, the insulating shell includes a accommodating cavity; a grounding column, the first end of the grounding column is located in the accommodating cavity, and the grounding column is slidably connected to the insulating shell; a threaded rod, the first end of the threaded rod passes through the first end surface of the insulating shell and extends into the accommodating cavity, the threaded rod is rotatably connected to the insulating shell, and the threaded rod is threadedly connected to the grounding column; wherein the threaded rod rotates to drive the grounding column to move axially along the insulating shell, so that the second end of the grounding column moves from the accommodating cavity to the outside of the accommodating cavity, or the second end of the grounding column moves from the outside of the accommodating cavity to the inside of the accommodating cavity.

[0008] In this technical solution, a accommodating cavity is provided in the insulating shell, which is used to accommodate the grounding column and the threaded rod. The first end of the grounding column is located in the accommodating cavity, and the grounding column can slide relative to the insulating shell, that is, the grounding column can slide in the axial direction of the insulating shell.

[0009] In this technical solution, the first end of the threaded rod passes through the top surface of the insulating shell and extends into the accommodating cavity of the insulating shell. The portion of the threaded rod extending into the accommodating cavity is threadedly connected to the grounding column, and the threaded rod can rotate relative to the insulating shell.

[0010] In this technical solution, when the threaded rod slides relative to the insulating shell, since the grounding post cannot rotate with the axis of the accommodating cavity as the rotation axis, and the threaded rod cannot slide relative to the insulating shell in the axial direction of the accommodating cavity, the grounding post can slide along the axial direction of the accommodating cavity under the drive of the threaded rod rotation, so that the second end of the grounding post slides from the accommodating cavity to the outside of the accommodating cavity, or the second end of the grounding post slides from the outside of the accommodating cavity to the inside of the accommodating cavity. And since the threaded rod and the grounding post are connected by threads, the rotation of the threaded rod can steplessly adjust the length of the grounding post extending out of the accommodating cavity.

[0011] In this technical solution, the insulating shell is made of insulating material, and the length of the accommodating cavity in the insulating shell is greater than or equal to the length of the grounding column. By setting the length of the accommodating cavity to be greater than or equal to the length of the grounding column, the grounding column can be completely accommodated in the accommodating cavity, thereby preventing the tip of the grounding column from causing harm to the staff when the grounding column is not in use.

[0012] It should be noted that the grounding pole is connected to the building equipment. Before controlling the operation of the building equipment, the second end of the grounding pole is moved from the accommodating cavity to the outside of the accommodating cavity and inserted into the ground, thereby grounding the building equipment.

[0013] In the technical solution of the present application, the grounding device includes an insulating shell, and a receiving cavity capable of receiving a grounding column is provided in the insulating shell. The grounding column can be completely received through the receiving cavity. When the grounding column is not in use, the tip of the grounding column is prevented from being exposed and injuring people. The tip of the grounding column can also be effectively protected, thereby improving the durability and safety of the grounding device. A threaded rod capable of rotating relative to the insulating shell is provided in the grounding device, and the threaded rod is threadedly connected to the grounding column. By rotating the threaded rod, the grounding column can be driven to slide up and down relative to the axial direction of the receiving cavity, so that the grounding column can be moved from the inside of the receiving cavity to the outside of the receiving cavity, and can also be moved from the outside of the receiving cavity to the inside of the receiving cavity. Moreover, since the threaded rod and the grounding column are threaded structures, the staff can stop rotating the threaded rod at any time during the process of controlling the telescopic movement of the grounding column relative to the insulating shell, so that the grounding column stops at the current position, thereby realizing flexible adjustment of the length of the part of the grounding column extending out of the insulating shell, further improving the scope of application of the grounding device.

[0014] In some technical solutions of the present application, a slide rail is provided on the inner wall of the insulating shell, and a slider is provided on the outer wall of the grounding column, and the slider can slide relative to the slide rail.

[0015] In this technical solution, the grounding device also includes a slide rail and a slider, the slide rail is arranged on the inner wall of the insulating shell, that is, the sliding opening direction faces the inside of the accommodating cavity, and the extension direction of the slide rail is parallel to the axis of the accommodating cavity. The slider is arranged on the outer wall of the grounding column, and the slider can slide in the slide rail.

[0016] Specifically, by arranging a slide rail on the inner wall of the insulating shell and a slider on the outer wall of the grounding post, the grounding post can only slide relative to the axis of the insulating shell and cannot rotate relative to the insulating shell. When the threaded rod rotates relative to the insulating shell, the grounding post is prevented from rotating with the threaded rod, so that the grounding post can only perform telescopic movement relative to the insulating shell.

[0017] It should be noted that the length of the slide rail can be designed according to actual needs. The length of the slide rail is positively correlated with the maximum length that the grounding column can extend out of the insulating shell, that is, the longer the length of the slide rail, the longer the maximum length that the grounding column can extend out of the insulating shell.

[0018] In the technical solution of the present application, a sliding rail and a slider are respectively arranged on the inner wall of the insulating shell and the outer wall of the grounding column, and the slider can slide in the sliding rail. The sliding rail and the slider limit the grounding column to prevent the grounding column from rotating relative to the insulating shell, ensuring that the grounding column can only telescopically slide relative to the insulating shell under the rotation of the threaded rod, thereby improving the stability of adjusting the length of the grounding column extending out of the insulating shell.

[0019] In some technical solutions of the present application, the number of slide rails is at least two, and the number of sliders matches the number of slide rails.

[0020] In this technical solution, the number of the slide rails and the number of the sliders are at least two, and the slide rails and the sliders are arranged one-to-one, that is, after the grounding column is installed in the accommodating cavity, each slider can slide in the corresponding slide rail.

[0021] In the technical solution of the present application, by setting the number of slide rails to be multiple and setting the number of sliders to be consistent with the number of slide rails, the stability of the sliding of the grounding column relative to the insulating shell can be further ensured.

[0022] In some technical solutions of the present application, a wiring hole is provided on the first end surface of the insulating shell, and the grounding device further includes:

[0023] A connecting wire, one end of which is connected to the grounding column, and the other end of which extends out of the insulating shell through the wiring hole and is connected to the building equipment.

[0024] In the technical solution, the grounding device further includes a wiring hole provided on the insulating shell, and a connecting wire passing through the wiring hole and connected at both ends to the grounding column and the building equipment. Specifically, the wiring hole is provided on the first end face of the insulating shell, and the wiring hole passes through the first end face of the insulating shell, that is, the wiring hole is a through hole. One end of the connecting wire is in the accommodating cavity, and one end of the connecting wire is connected to the grounding column, and the other end of the connecting wire is outside the accommodating cavity, and the other end of the connecting wire is connected to the building equipment.

[0025] In the technical solution of the present application, the connecting wire in the grounding device is located in the accommodating cavity, the insulating shell can provide certain protection for the connecting wire, and the grounding column is connected to the building equipment through the connecting wire, so that the building equipment is grounded through the grounding column.

[0026] In some technical solutions of the present application, the grounding column includes: a first column, the first column is provided with a first thread, the first column is connected to the threaded rod through the first thread and the second thread, and the second thread is arranged on the outer wall of the threaded rod; a second column, which is detachably connected to the first column, and the bottom of the second column is conical.

[0027] In this technical solution, the grounding column includes a first column and a second column, the first column is provided with a threaded hole, the threaded hole is provided with a first thread, the outer wall of the threaded rod is provided with a second thread, the first column is threadedly connected to the threaded rod through the first thread and the second thread, and during the rotation of the threaded rod, the grounding column can be driven to telescopically move relative to the insulating shell through the transmission of the first thread and the second thread. The second column is detachably connected to the first column, and the bottom of the second column is the tip of the grounding column.

[0028] In the technical solution of the present application, since the bottom of the second column is conical, it is convenient to insert the grounding column under the ground. The first column and the second column are detachably connected. In the process of inserting the grounding column into the ground, since the second column contacts the ground first, as the grounding device is used, the second column is more worn than the first column. Therefore, the first column and the second column are detachably connected, which facilitates the replacement and maintenance of the second column. After the tip of the grounding column is worn, only the second column needs to be replaced, which reduces the cost of use.

[0029] In some technical solutions of the present application, the first column and the second column are detachably connected by bolts.

[0030] In the technical solution of the present application, the first column and the second column are connected by bolts, so that the staff can easily adjust whether the first column and the second column are connected by disassembling and assembling the bolts, further simplifying the operating steps of the staff.

[0031] In some technical solutions of the present application, the grounding device further includes: a positioning plate fixedly connected to the second end face of the insulating shell; a positioning pin penetrating the positioning plate and movably connected to the positioning plate, wherein the number of the positioning pins is at least two.

[0032] In this technical solution, the grounding device also includes a positioning plate and a positioning pin, the positioning plate is arranged on the second end face of the insulating shell, and the positioning plate is parallel to the second end face. The positioning pin passes through the positioning plate, and the direction of the tip of the positioning pin matches the direction in which the grounding column moves out of the accommodating cavity.

[0033] Specifically, when the grounding device is used, the positioning plate can fit the ground, and the positioning pins can penetrate the top surface of the positioning plate and be inserted into the ground, which can assist in positioning the grounding device. When the grounding column is inserted into the ground, the positioning pins are inserted into the ground at the same time. When the grounding column is subjected to external force, the positioning pins can reinforce the connection between the grounding device and the ground.

[0034] In the technical solution of the present application, positioning and positioning pins are also provided in the grounding device. When the grounding column is inserted under the ground, the positioning pins and the positioning plate can stabilize the connection between the grounding device and the ground, thereby improving the stability of the grounding device in use.

[0035] In some technical solutions of the present application, the grounding device further includes: a bearing, which is fixedly arranged on the first end surface of the insulating shell, wherein the threaded rod is rotatably connected to the insulating shell through the bearing.

[0036] In the technical solution of the present application, a bearing is also provided in the grounding device, which is fixedly connected to the first end face of the insulating shell, and the threaded rod is connected to the axial direction. The threaded rod can rotate relative to the insulating shell through the bearing, thereby improving the stability of the threaded rod's rotation relative to the insulating shell.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0051] Refer to the following Figures 1 to 4 A grounding device 100 and a building equipment 200 according to some embodiments of the present invention are described.

[0052] Figure 1 One of the structural schematic diagrams of the grounding device provided in some embodiments of the present application is shown, Figure 2 The second structural schematic diagram of the grounding device provided in some embodiments of the present application is shown. Figure 3 The third structural schematic diagram of the grounding device provided in some embodiments of the present application is shown as follows: Figure 1 , Figure 2 and Figure 3As shown, a grounding device 100 is provided in the first embodiment of the utility model, comprising: an insulating shell 110, a grounding column 120 and a threaded rod 130. The insulating shell 110 comprises a receiving chamber; one end of the grounding column 120 is located in the receiving chamber, and the grounding column 120 is slidably connected to the insulating shell 110; the first end of the threaded rod 130 passes through the first end surface of the insulating shell 110 and extends into the receiving chamber, the threaded rod 130 is rotatably connected to the insulating shell 110, and the threaded rod 130 is threadedly connected to the grounding column 120; wherein the threaded rod 130 rotates to drive the grounding column 120 to move along the axial direction of the insulating shell 110, so that the second end of the grounding column 120 moves from the receiving chamber to the outside of the receiving chamber, or the second end of the grounding column 120 moves from the outside of the receiving chamber to the inside of the receiving chamber.

[0053] In this embodiment, a accommodating cavity is provided in the insulating shell 110, and the accommodating cavity is used to accommodate the grounding column 120 and the threaded rod 130. The first end of the grounding column 120 is located in the accommodating cavity, and the grounding column 120 can slide relative to the insulating shell 110, that is, the grounding column 120 can slide in the axial direction of the insulating shell 110.

[0054] In this embodiment, the first end of the threaded rod 130 passes through the top surface of the insulating shell 110 and extends into the accommodating cavity of the insulating shell 110. The portion of the threaded rod 130 extending into the accommodating cavity is threadedly connected to the grounding column 120, and the threaded rod 130 can rotate relative to the insulating shell 110.

[0055] like Figure 2 As shown, the receiving cavity in the insulating shell 110 is cylindrical, and the grounding post 120 can slide along the extension direction B of the axis A of the cylindrical receiving cavity. The threaded rod 130 can rotate relative to the insulating shell 110 with the axis A of the receiving cavity as the rotation axis.

[0056] In this embodiment, when the threaded rod 130 slides relative to the insulating shell 110, since the grounding post 120 cannot rotate with the axis of the accommodating cavity as the rotation axis, and the threaded rod 130 cannot slide in the axial direction of the accommodating cavity relative to the insulating shell 110, the grounding post 120 can slide along the axial direction of the accommodating cavity driven by the rotation of the threaded rod 130, so that the second end of the grounding post 120 slides from the inside of the accommodating cavity to the outside of the accommodating cavity, or the second end of the grounding post 120 slides from the outside of the accommodating cavity to the inside of the accommodating cavity. And since the threaded rod 130 and the grounding post 120 are connected by threads, the rotation of the threaded rod 130 can steplessly adjust the length of the grounding post 120 extending out of the accommodating cavity.

[0057] like Figure 2 As shown, Figure 2The second end of the grounding column 120 is located inside the accommodating cavity. The staff rotates the threaded rod 130 clockwise, and the grounding column 120 is driven by the threaded rod 130 to move downward along the axis direction of the accommodating cavity, that is, to move to the outside of the accommodating cavity until the grounding column 120 moves outside the accommodating cavity. During the sliding process of the grounding column 120, the staff can stop rotating the threaded rod 130 at any time to make the grounding column 120 stop at the current position.

[0058] like Figure 3 As shown, Figure 3 The second end of the grounding column 120 is located outside the accommodating cavity. The staff rotates the threaded rod 130 counterclockwise, and the grounding column 120 is driven by the threaded rod 130 to move upward along the axial direction of the accommodating cavity, that is, move toward the inside of the accommodating cavity until the grounding column 120 moves into the accommodating cavity. During the sliding process of the grounding column 120, the staff can stop rotating the threaded rod 130 at any time to make the grounding column 120 stop at the current position.

[0059] In this embodiment, the insulating shell 110 is made of insulating material, and the length of the accommodating cavity in the insulating shell 110 is greater than or equal to the length of the grounding column 120. By setting the length of the accommodating cavity to be greater than or equal to the length of the grounding column 120, the grounding column 120 can be completely received in the accommodating cavity, thereby preventing the tip of the grounding column 120 from causing harm to the staff when the grounding column 120 is not in use.

[0060] It should be noted that the grounding pole 120 is connected to the building equipment. Before controlling the operation of the building equipment, the second end of the grounding pole 120 is moved from the accommodating cavity to the outside of the accommodating cavity and inserted into the ground, so as to ground the building equipment.

[0061] In the embodiment of the present application, the grounding device 100 includes an insulating shell 110, and a receiving cavity capable of accommodating a grounding post 120 is opened in the insulating shell 110. The grounding post 120 can be completely stored in the receiving cavity. When the grounding post 120 is not in use, the tip of the grounding post 120 is prevented from being exposed and injuring people. The tip of the grounding post 120 can also be effectively protected, thereby improving the durability and safety of the grounding device 100. A threaded rod 130 that can rotate relative to the insulating shell 110 is provided in the grounding device 100, and the threaded rod 130 is threadedly connected to the grounding column 120. By rotating the threaded rod 130, the grounding column 120 can be driven to slide up and down relative to the axial direction of the accommodating cavity, so that the grounding column 120 can be moved from the accommodating cavity to the outside of the accommodating cavity, and can also be moved from the outside of the accommodating cavity to the inside of the accommodating cavity. In addition, since the threaded rod 130 and the grounding column 120 are threaded structures, the staff can stop rotating the threaded rod 130 at any time during the process of controlling the telescopic movement of the grounding column 120 relative to the insulating shell 110, so that the grounding column 120 stops at the current position, thereby realizing flexible adjustment of the length of the part of the grounding column 120 extending out of the insulating shell 110, thereby further improving the scope of application of the grounding device 100.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a slide rail 112 is disposed on the inner wall of the insulating shell 110 , and a slider 122 is disposed on the outer wall of the grounding column 120 , and the slider 122 can slide relative to the slide rail 112 .

[0063] In this embodiment, the grounding device 100 further includes a slide rail 112 and a slider 122. The slide rail 112 is disposed on the inner side wall of the insulating shell 110, that is, the sliding opening direction faces the inside of the accommodating cavity, and the extension direction of the slide rail 112 is parallel to the axis of the accommodating cavity. The slider 122 is disposed on the outer side wall of the grounding column 120, and the slider 122 can slide in the slide rail 112.

[0064] Specifically, by providing the slide rail 112 on the inner wall of the insulating shell 110 and the slider 122 on the outer wall of the grounding post 120, the grounding post 120 can only slide relative to the axis of the insulating shell 110, and cannot rotate relative to the insulating shell 110. When the threaded rod 130 rotates relative to the insulating shell 110, the grounding post 120 is prevented from rotating with the threaded rod 130, so that the grounding post 120 can only perform telescopic movement relative to the insulating shell 110.

[0065] It should be noted that the length of the slide rail 112 can be designed according to actual needs. The length of the slide rail 112 is positively correlated with the maximum length that the grounding column 120 can extend out of the insulating shell 110, that is, the longer the length of the slide rail 112, the longer the maximum length that the grounding column 120 can extend out of the insulating shell 110.

[0066] In some possible implementations, the slide rail 112 may be disposed on an outer side wall of the grounding column 120 , and the slider 122 may be disposed on an inner side wall of the insulating shell 110 .

[0067] In the embodiment of the present application, a slide rail 112 and a slider 122 are respectively provided on the inner wall of the insulating shell 110 and the outer wall of the grounding column 120, and the slider 122 can slide in the slide rail 112. The slide rail 112 and the slider 122 limit the grounding column 120 to prevent the grounding column 120 from rotating relative to the insulating shell 110, and ensure that the grounding column 120 can only telescopically slide relative to the insulating shell 110 under the rotation of the threaded rod 130, thereby improving the stability of adjusting the length of the grounding column 120 extending out of the insulating shell 110.

[0068] In some embodiments of the present application, the number of the slide rails 112 is at least two, and the number of the sliders 122 matches the number of the slide rails 112 .

[0069] In this embodiment, the number of the slide rails 112 and the sliders 122 is at least two, and the slide rails 112 and the sliders 122 are arranged one-to-one, that is, after the grounding column 120 is installed in the accommodating cavity, each slider 122 can slide in the corresponding slide rail 112.

[0070] Exemplarily, the number of the slide rails 112 is two, the number of the sliders 122 is also two, and the two slide rails 112 are axially symmetrically arranged with the axis of the accommodating cavity as the axis of symmetry.

[0071] Exemplarily, the number of the slide rails 112 is 3, the number of the sliders 122 is also 3, and the three slide rails 112 are centrally symmetrically arranged with the axis of the accommodating cavity as the center of symmetry.

[0072] In the embodiment of the present application, by setting the number of the slide rails 112 to be multiple and setting the number of the sliders 122 to be consistent with the number of the slide rails 112 , the stability of the sliding of the grounding column 120 relative to the insulating shell 110 can be further ensured.

[0073] In some embodiments of the present application, a wiring hole 114 is provided on the first end surface of the insulating shell 110, and the grounding device 100 further includes:

[0074] A connecting wire 140 , one end of which is connected to the threaded rod 130 , and the other end of which extends out of the insulating housing 110 through the wiring hole 114 and is connected to the building equipment.

[0075] In this embodiment, the grounding device 100 further includes a wiring hole 114 provided on the insulating shell 110, and a connecting wire 140 passing through the wiring hole 114 and having two ends respectively connected to the grounding column 120 and the building equipment. Specifically, the wiring hole 114 is provided on the first end surface of the insulating shell 110, and the wiring hole 114 passes through the first end surface of the insulating shell 110, that is, the wiring hole 114 is a through hole. One end of the connecting wire 140 is in the accommodating cavity, and one end of the connecting wire 140 is connected to the grounding column 120, and the other end of the connecting wire 140 is outside the accommodating cavity, and the other end of the connecting wire 140 is connected to the building equipment.

[0076] Exemplarily, the connection line 140 is selected as a power line, and the connection line 140 has a conductive capability so as to ground the equipment used in the building.

[0077] In the embodiment of the present application, the connecting wire 140 in the grounding device 100 is located in the accommodating cavity, the insulating shell 110 can provide a certain degree of protection for the connecting wire 140 , and the grounding column 120 is connected to the building equipment through the connecting wire 140 , so that the building equipment is grounded through the grounding column 120 .

[0078] In some embodiments of the present application, the grounding column 120 includes: a first column 124 and a second column 126, the first column 124 is provided with a first thread, the first column 124 is connected to the threaded rod 130 through the first thread and the second thread, and the second thread is provided on the outer wall of the threaded rod 130; the second column 126 is detachably connected to the first column 124, and the bottom of the second column 126 is conical.

[0079] In this embodiment, the grounding column 120 includes a first column 124 and a second column 126. The first column 124 is provided with a threaded hole, and a first thread is provided in the threaded hole. The outer wall of the threaded rod 130 is provided with a second thread. The first column 124 is threadedly connected to the threaded rod 130 through the first thread and the second thread. During the rotation of the threaded rod 130, the transmission of the first thread and the second thread can drive the grounding column 120 to telescopically move relative to the insulating shell 110. The second column 126 is detachably connected to the first column 124, and the bottom of the second column 126 is the tip of the grounding column 120.

[0080] Exemplarily, the first column 124 is in a cylindrical shape, and the second column 126 is in a conical shape.

[0081] In the embodiment of the present application, since the bottom of the second column 126 is conical, it is convenient to insert the grounding column 120 under the ground. The first column 124 and the second column 126 are detachably connected. In the process of inserting the grounding column 120 into the ground, since the second column 126 contacts the ground first, as the grounding device is used, the second column 126 is more worn than the first column 124. Therefore, the first column 124 and the second column 126 are detachably connected, which facilitates the replacement and maintenance of the second column 126.
