Description

Technical Field

[0001] The invention relates to the technical field of electric tools, in particular to an electric insulating grounding rod clamp. Background Art

[0002] The insulated grounding rod clamp is an important tool used in power construction, mainly composed of reinforced shell, piercing blade, sealing gasket and other parts. It has waterproof performance and good electrical effect. Its role is mainly reflected in two aspects: one is to prevent the sudden power supply of the equipment and the induced voltage of the adjacent high-voltage live equipment from causing harm to the human body when the high-voltage equipment is shut down for maintenance or other work; the other is to discharge the residual charge of the power-off equipment to ensure the safety of the operation.

[0003] For example, an insulated grounding rod clamp for 35kV power substation construction with publication number CN218548829U includes a grounding rod body, an adjustment support mechanism for connecting and supporting multiple insulated grounding rods to prevent the insulated grounding rods from shaking during construction, and a clamping mechanism for collecting and clamping multiple insulated grounding rods after use to prevent the insulated grounding rod clamp from being inconvenient to carry. A fixed block is provided on the outside of the grounding rod body, a clamping mechanism is provided in front of the fixed block, and an adjustment support mechanism is provided below the fixed block and outside the grounding rod body. The wire clamp is driven to clamp the wire by rotating the grounding rod body, and the distance between two adjacent insulated grounding rod clamps can be adjusted by the upper adjustment block and the lower adjustment block, so as to support the insulated grounding rod clamp when in use. The insulated grounding rod clamp can be clamped and collected by the clamping block and the limit block, so as to facilitate carrying the insulated grounding rod clamp.

[0004] The above-mentioned prior art realizes the connection support between the two rods by adjusting the supporting mechanism. When the grounding rod is hung on the electric wire, the two adjacent rods are connected by adjusting the supporting mechanism to prevent the insulating grounding rod clamp from shaking during use, causing the problem of the wire clamp being loose. However, the use of the adjusting supporting mechanism requires manual operation by the staff, and generally, this kind of insulating grounding rod clamp acts on overhead lines at high altitudes, which is not convenient for the staff to operate on site.

[0005] Secondly, the prior art also provides a clamping mechanism, through which multiple rods can be connected into one, and the purpose is only for easy carrying when not in use. The adjusting support mechanism has been explained above, which also connects adjacent rods into one. It can be seen that the functions of the clamping mechanism and the adjusting support mechanism are repeated, and the optimization of the mechanism is not achieved.

[0006] In addition, in order to solve the problem of loose wire clamps, the above-mentioned prior art only connects multiple rods by adjusting the supporting mechanism. However, when only one rod is used, the adjusting supporting mechanism does not work. Moreover, the prior art does not start from the problem of loose wire clamps itself. There are many inconveniences in setting up the adjusting supporting mechanism and there are limitations in its use.

[0007] Based on this, under the above statement, the above-mentioned prior art still has room for optimization and improvement. Summary of the invention

[0040] The following is combined with Figures 1 to 11 The present invention is described in further detail.

[0041] See also Figure 1 and Figure 2 An electric insulated grounding rod clamp comprises a rod body 1, a connection box 2 connected to the rod body 1, and a wire clamp mechanism 3 installed on the connection box 2. The rod body 1 and the connection box 2 are detachable and can be rotated as needed to determine whether the rod body 1 needs to cooperate. For example, if the wire is at a high altitude, the rod body 1 needs to cooperate to achieve the wire clamp mechanism 3 on the connection box 2 to clamp the wire. If it is at a low altitude and the staff can reach it, the rod body 1 does not need to cooperate. At the same time, the detachable cooperation between the rod body 1 and the connection box 2 is helpful for daily carrying and storage.

[0042] Furthermore, two connection boxes 2 can be connected to form a whole, that is, multiple connection boxes 2 can be spliced ​​into one, and each connection box 2 is provided with a wire clamp mechanism 3. At this time, one rod body 1 can be used to clamp multiple wire clamp mechanisms 3 on different wires at the same time, which is mainly used for cables and wires installed in parallel at high altitudes. At the same time, the connection box 2 can also be used alone, that is, one rod body 1, one connection box 2 and one wire clamp mechanism 3 form a set of independent insulating grounding rod clamps.

[0043] See also Figures 2 to 4 The wire clamp mechanism 3 includes a vertical plate 31, one side of the vertical plate 31 is provided with a vertical screw 32 which is rotatable through a bracket, the upper end of the vertical screw 32 is threadedly sleeved with a threaded sleeve 33, the upper end of the vertical plate 31 is provided with a support plate 34 for the threaded sleeve 33 to pass longitudinally, the upper end of the vertical plate 31 is provided with an L-shaped frame 35, a clamping plate 36 is slidably provided on one side of the vertical section of the L-shaped frame 35, and the clamping plate 36 is connected to the upper end of the threaded sleeve 33, a transverse plate 37 is provided on the top of the L-shaped frame 35, and a clamping assembly 38 is provided between the transverse plate 37 and the clamping plate 36 for clamping the wire therein.

[0044] When the wire is placed between the transverse plate 37 and the clamping plate 36, that is, placed in the clamping assembly 38, the vertical screw 32 rotates to drive the threaded sleeve 33 to start moving upward, pushing the clamping plate 36 upward, so that the clamping assembly 38 clamps the wire to achieve the clamping of the wire.

[0045] The clamping assembly 38 includes an upper clamping plate 380 and a lower clamping plate 381. The upper clamping plate 380 is arranged at the bottom of the transverse plate 37. The opposite sides of the upper clamping plate 380 and the lower clamping plate 381 are both arranged as arc-shaped concave structures. Two sliding rods 382 are arranged at the bottom of the lower clamping plate 381, and the sliding rods 382 are slidably passed through the clamping plate 36, and a clamping spring 383 is arranged between the lower clamping plate 381 and the clamping plate 36.

[0046] When the wire is placed between the upper clamping plate 380 and the lower clamping plate 381 , the abutting plate 36 moves upward under the push of the threaded sleeve 33 , so that the lower clamping plate 381 moves upward to clamp the wire between the upper clamping plate 380 and the lower clamping plate 381 .

[0047] Although the upper clamping plate 380 and the lower clamping plate 381 can clamp the wire, it is still easy to cause the wire to fall off when the wire clamp shakes. Therefore, based on the above, the present invention has a rectangular opening on the horizontal plate 37, and a blocking plate 384 is provided in the rectangular opening through a torsion spring. The torsion spring can drive the blocking plate 384 to rotate downward to a vertical state (such as Figure 3 In the state shown in the figure), when the wire is clamped between the upper clamping plate 380 and the lower clamping plate 381, the blocking plate 384 will be vertically arranged on one side. At this time, the upper clamping plate 380 and the lower clamping plate 381 are located between the blocking plate 384 and the L-shaped plate 41, which can effectively prevent the problem of the wire being detached.

[0048] An extension protrusion 385 is provided at one end of the blocking plate 384 close to the rotation center, a pull rope 386 is connected to one side of the extension protrusion 385, a sliding protrusion 387 is provided on one side of the clamping plate 36, and a strip hole for sliding the sliding protrusion 387 is provided on the vertical section of the L-shaped frame 35, the end of the pull rope 386 facing away from the extension protrusion 385 is connected to the sliding protrusion 387, and a rectangular groove for accommodating the pull rope 386 and the extension protrusion 385 is provided on the transverse plate 37, and a rotating rod 388 for limiting the moving trajectory of the pull rope 386 is provided in the rectangular groove, and a rotating rod 388 for limiting the moving trajectory of the pull rope 386 is also provided on the side of the transverse plate 37 facing the sliding protrusion 387.

[0049] like Figure 4 As shown in the figure, it is the initial state of the wire clamp mechanism 3. In this state, affected by the height of the clamping plate 36, the pull rope 386 will pull the extension protrusion 385, so that the blocking plate 384 rotates to a horizontal state and is stored in the rectangular opening; when the wire clamp mechanism 3 is moved to the wire, the wire is ensured to be between the upper clamping plate 380 and the lower clamping plate 381. At this time, the threaded sleeve 33 drives the clamping plate 36 to move upward, so that the wire can be clamped between the upper clamping plate 380 and the lower clamping plate 381, and due to the upward movement of the clamping plate 36, the sliding protrusion 387 releases the restriction on the pull rope 386, so that the blocking plate 384 rotates downward to a vertical state (such as Figure 3 shown) to prevent the wire from accidentally becoming detached.

[0050] However, since the blocking plate 384 is rotated into a vertical state under the action of the torsion spring, that is, when the wire is disengaged from the clamping between the upper clamping plate 380 and the lower clamping plate 381, the wire may push the blocking plate 384 and disengage. Therefore, the present invention provides a limiting plate 389 on the clamping plate 36. When the blocking plate 384 is in a vertical state, the limiting plate 389 is located on the side of the blocking plate 384 away from the lower clamping plate 381, and is used to limit the blocking plate 384 from rotating toward a horizontal state.

[0051] See also Figure 5 and Figure 6 A T-shaped bottom plate 40 is provided at the bottom of the vertical plate 31 and is slidably arranged on the top of the connecting box 2. An inverted L-shaped plate 41 is connected to one side of the T-shaped bottom plate 40. The lower end of the vertical screw 32 is rotatably penetrated on the horizontal section of the L-shaped plate 41. The lower end of the vertical screw 32 is located in the L-shaped plate 41 and is provided with a bevel gear 1 42. A rotating shaft 43 is rotatably penetrated on the vertical section of the L-shaped plate 41. A bevel gear 2 44 meshing with the bevel gear 1 42 is installed on the rotating shaft 43. A through polygonal through hole is opened in the middle of the rotating shaft 43. A polygonal rotating shaft 45 is provided in the polygonal through hole of the rotating shaft 43 and slides along its axial direction.

[0052] The connection box 2 is configured as a hollow shell structure, with an installation opening provided on one side of the connection box 2, in which a side plate 46 is detachably installed, an auxiliary ring 47 is rotatably provided on the side plate 46, and a polygonal through hole slidably matched with the polygonal rotating shaft 45 is also provided in the auxiliary ring 47, and an installation window for the horizontal section of the L-shaped plate 41 to slide is provided at the bottom of the connection box 2.

[0053] When the wire clamp mechanism 3 needs to be installed on the connection box 2, the side plate 46 is first removed, and then the L-shaped plate 41 is moved from the installation opening into the connection box 2, and the horizontal section of the L-shaped plate 41 slides along the installation window into the connection box 2, and then the auxiliary ring 47 of the side plate 46 is passed through the polygonal shaft 45, and finally the side plate 46 is detachably installed at the installation opening of the connection box 2, that is, Figure 5 Status shown.

[0054] The top of the connection box 2 is provided with a strip-shaped through hole 21 for the vertical section of the T-shaped bottom plate 40 to slide, and the top of the connection box 2 is provided with a plurality of threaded holes 22 for fastening the bolts on the T-shaped bottom plate 40 .

[0055] See also Figure 5 , Figure 7 and Figure 8 A transmission shaft 50 is provided in the connection box 2 through a rotating bracket, and the transmission shaft 50 is coaxially distributed with the rotating shaft 43. The transmission shaft 50 is also provided with a polygonal through hole along its axial direction for sliding cooperation with the polygonal rotating shaft 45, and a bevel gear 3 51 is provided on the transmission shaft 50.

[0056] A mounting cylinder 52 with a bottom opening is provided at the bottom of the connecting box 2, and a mounting shaft is rotatably provided at the top of the mounting cylinder 52. The mounting shaft extends into the connecting box 2 and is installed with a bevel gear 4 53 meshing with the bevel gear 3 51, and a polygonal rotating tooth 54 located in the mounting cylinder 52 is installed at the bottom of the mounting shaft.

[0057] A driving cylinder 55 with an open upper end is threadedly connected to the top of the rod body 1, and a partition ring is provided on the outer side wall of the driving cylinder 55 to divide the outer side wall of the driving cylinder 55 into an upper section and a lower section. Both the upper section and the lower section of the driving cylinder 55 are provided with external threads, and the upper section of the driving cylinder 55 is threadedly connected to the mounting cylinder 52. A motor 56 is provided in the driving cylinder 55, and an adapter ring 57 that rotates in the mounting cylinder 52 is provided at the output end of the motor 56, and a tooth groove that slides with the polygonal rotating tooth 54 is provided in the adapter ring 57.

[0058] See also Fig.11The rod body 1 is composed of a plurality of rod shafts 11, an internal threaded hole 12 is provided at the upper end of the rod shaft 11, and an external threaded protrusion 13 is provided at the lower end. Two adjacent rod shafts 11 are installed and fixed by the threaded cooperation of the internal threaded hole 12 and the external threaded protrusion 13. The internal threaded hole 12 of the uppermost rod shaft 11 is installed and fixed by the external thread of the lower section of the driving cylinder 55, and the external threaded protrusion 13 of the lowermost rod shaft 11 is threadedly connected with a handle 14.

[0059] During the specific implementation process, when it is needed, the external thread of the upper section of the driving cylinder 55 is installed in the mounting cylinder 52, and at the same time, it is ensured that the adapter ring 57 in the driving cylinder 55 slides into the annular area between the mounting cylinder 52 and the polygonal gear 54, and the tooth groove in the adapter ring 57 will slide with the polygonal gear 54; then the motor 56 is started to drive the adapter ring 57 to rotate synchronously, and the adapter ring 57 cooperates with the polygonal gear 54 through the tooth groove, so that the adapter ring 57 can drive the polygonal gear 54 to rotate, and then drive the bevel gear four 53 to rotate through the mounting shaft, the meshing of the bevel gear four 53 and the bevel gear three 51 will realize the rotation of the transmission shaft 50, and the transmission shaft 50 will drive the polygonal shaft 45 to rotate, and then drive the rotating shaft 43 to rotate, so that the bevel gear two 44 is engaged with the bevel gear one 42 to realize the rotation of the vertical screw 32, thereby realizing the operation and use of the wire clamp mechanism 3.

[0060] The L-shaped plate 41 slides along its axial direction on the polygonal rotating shaft 45 through the rotating shaft 43, so that the vertical plate 31 can be driven to move through the T-shaped bottom plate 40, thereby realizing the movement of the wire clamp mechanism 3. Therefore, when multiple connection boxes 2 are detachably connected in sequence, that is, multiple wire clamp mechanisms 3 are used at the same time to clamp multiple wires respectively, and the distance between two wires is not the same, in order to ensure that they can be aligned and clamped at the same time, it is necessary to adjust the distance between two adjacent wire clamp mechanisms 3, that is, to adjust the distance between two adjacent vertical plates 31. Therefore, the present invention adjusts the distance by sliding the rotating shaft 43 on the polygonal rotating shaft 45, and at the same time does not affect the rotation of the polygonal rotating shaft 45 to drive the rotation of the rotating shaft 43.

[0061] See also Figure 5 When the two connection boxes 2 are docked and installed, it is necessary to provide power for the rotation of the polygonal shaft 45. For this purpose, the polygonal shaft 45 of the present invention passes through the connection box 2 at one end close to the side plate 46, and the end of the transmission shaft 50 at the other end of the connection box 2 is rotatably penetrated on the side wall of the connection box 2. When the two connection boxes 2 are docked, the polygonal shafts 45 on the opposite sides of the two connection boxes 2 are penetrated and connected with the transmission shaft 50 to realize the synchronous connection of the power transmission, that is, the motor 56 arranged at the upper end of the rod body 1 can control the synchronous rotation of all the polygonal shafts 45, that is, the synchronous operation of multiple wire clamp mechanisms 3 can be controlled.

[0062] See also Fig. 9 and Fig.10 The front and rear inner walls of the connection box 2 are both horizontally slidably provided with a connection strip 61, and the two ends of the connection strip 61 are respectively threadedly connected with a bolt 1 62 and a bolt 2 63, wherein the bolt 1 62 is located at one end of the connection strip 61 close to the middle of the connection box 2, and the side wall of the connection box 2 is provided with a horizontal sliding hole 64 for the bolt 1 62 to slide, and a round hole for the bolt 2 63 to pass through is provided on the side of the connection box 2 away from the horizontal sliding hole 64.

[0063] When two connection boxes 2 are docked, the connection strip 61 is pushed toward the adjacent connection box 2 by bolt 1 62 until bolt 2 63 threadedly matched with the connection strip 61 passes through the corresponding circular hole and is threadedly connected to the connection strip 61. At this time, the two connection boxes 2 are docked and installed.

[0064] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
