Description

Technical Field

[0001] This utility model relates to the field of anti-static jumper wire installation technology, and in particular to a quick installation device for anti-static jumper wires. Background Technology

[0002] In pipeline systems involving flammable and explosive media, such as those in the petroleum and chemical industries, flange connections may experience excessive resistance due to factors such as insufficient insulating gaskets, corrosion, or a lack of bolts. This can prevent the timely discharge of static electricity or lightning-induced current. When the potential difference accumulates to a certain level, it may break down the air gap, generating sparks and causing serious accidents. Therefore, it is necessary to install jumper wires to ensure electrical continuity.

[0003] Traditional jumper wire installation involves using a wrench to remove the flange connection bolts in a diagonal sequence, then placing the terminals at both ends of the jumper wire onto the bolts on both flanges, and finally threading the original bolts back through the terminals and flange bolt holes. The nuts are then initially tightened with a wrench to ensure a tight fit between the terminals and the bolts and flange contact surfaces without any obvious gaps, thus completing the installation process. However, in actual use, the traditional jumper wire installation method usually requires the removal of bolts to install the jumper wire. The frequent disassembly and assembly operations are quite cumbersome, which not only makes it inefficient, but may also cause medium leakage during the disassembly process, leading to serious production safety accidents. Utility Model Content

[0004] To overcome the problem that existing jumper installation methods usually require the removal of bolts to install jumpers, the frequent disassembly and assembly operations are cumbersome, which not only leads to low efficiency, but may also cause medium leakage during disassembly, resulting in serious production safety accidents.

[0005] The technical solution of this utility model is: a quick-installation device for anti-static jumper wires, comprising: The installation pliers include two plier handles, a plier head disposed at one end of the plier handles, and a jaw formed at the top of the plier head; The jumper cable includes a female buckle washer and a female buckle washer, a connecting piece fixedly connected to one side of the female buckle washer, a fixing piece fixedly connected to the other side of the female buckle washer, a wire connected to one side of the fixing piece, an opening groove formed on one side of the bottom of the female buckle washer, and a mating groove formed on the other side of the bottom of the female buckle washer.

[0006] Preferably, the female and male fasteners can be pre-applied separately to the bolts. The special shape of the jaws in the installation pliers allows them to be quickly fitted onto the female and male fasteners and the outside of the bolt. Under the pressure of the installation pliers, the female and male fasteners tightly wrap around the bolt, and their sides bend along the bolt's curvature to form a mechanical interlock. Initial fixing can be completed in one operation, changing the cumbersome process of traditional methods that may require operating each bolt individually or using additional tools. At the same time, the connecting piece on one side of the male fastener passes through the opening groove on the female fastener and is fixed in reverse, which restricts the lateral and axial sliding of the jumper wire on the bolt surface, greatly ensuring the reliability and conductivity of the jumper wire connection.

[0007] Preferably, a biting edge is fixedly connected to one side of the jaw cavity, and the biting edge is set at a 45-degree angle to the jaw.

[0008] Preferably, the two clamp handles are arranged vertically, and a shaft is movably connected between the two clamp handles.

[0009] Preferably, the two clamp heads are arranged side by side, and the inner contour of the clamp jaws matches the outer contour of a conventional hexagonal bolt and can fit against the side of the hexagonal bolt.

[0010] Preferably, the jaws contact the female and male thread washers, both of which have tapered sides and their widths match the axial width of the hexagonal bolt. The female and male thread washers are attached to the surface of the hexagonal bolt.

[0011] Preferably, one end of the fixing piece extends into the inner cavity of the fitting groove and fits into the inner cavity of the fitting groove.

[0012] Preferably, one end of the connecting piece penetrates the inner cavity of the opening groove and is movably connected to the inner cavity of the opening groove, and one end of the connecting piece contacts the female buckle gasket.

[0013] The beneficial effects of this utility model are as follows: By setting up a special installation clamp, the special shape of the clamp jaws allows it to quickly fit over the female and male threaded washers and the outside of the bolt. The female and male threaded washers can be pre-separated and attached to the bolt, and the initial fixing can be completed in one operation with the clamp jaws. This changes the cumbersome process of traditional methods that may require operating each bolt individually or using additional tools. By tightly wrapping the bolt with a jumper wire, the reliability of the connection and the conductivity are guaranteed. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1 Please see Figure 1-5 This utility model provides an embodiment of an anti-static jumper cable quick installation device, comprising: an installation clamp 100, including two clamp handles 110, a clamp head 120 disposed at one end of the clamp handles 110, and a clamp jaw 130 opened at the top of the clamp head 120; and a jumper cable 200, including a female buckle washer 210 and a female buckle washer 220, a connecting piece 230 fixedly connected to one side of the female buckle washer 220, a fixing piece 240 fixedly connected to the other side of the female buckle washer 220, a wire 250 connected to one side of the fixing piece 240, an opening groove 270 opened at one bottom side of the female buckle washer 210, and a mating groove 260 opened at the other bottom side of the female buckle washer 210.

[0018] During operation, firstly, the fixing piece 240 of the female gasket 220 is extended into the mating groove 260 on the female gasket 210, connecting the female gasket 210 and the female gasket 220. Simultaneously, the wire 250 is connected to the fixing piece 240, forming the jumper wire 200. Then, the female gasket 220 and the female gasket 210 are separated along the extension direction, so that their inner surfaces fit against the hexagonal bolt body, and their sides are pressed against the flange face. Next, the clamp handle 110 of the installation clamp 100 is opened. The clamp handle 110, centered around the shaft 150, drives the clamp head 120 to unfold. Then, it is pressed tightly against the flange side, and through the clamp jaws 130, it is slipped onto the female gasket 210 and the female gasket 220 from the outside, simultaneously pulling outwards and applying pressure to the clamp handle 110. The clamp handle 110, under pressure, drives the clamp head 120 to close, thereby closing the clamp jaws. The clamp 130 is in close contact with the female clamp 210 and the male clamp 220. Due to the shape limitation of the clamp 130 and the bolt, the female clamp 210 and the male clamp 220 will adhere to the outer surface of the hexagonal bolt after being stressed, and their sides will bend towards the bolt body along the edge curvature of the bolt. Finally, the connecting piece 230 on one side of the male clamp 220 passes through the opening groove 270 on the female clamp 210 and extends towards the male clamp 220 along the inner edge of the opening groove 270, bending and fixing in the opposite direction. This allows the jumper wire 200 to be firmly fixed to the bolt surface without disassembling the bolt, which is more convenient. In this fixing method, the side bending of the female clamp 210 and the male clamp 220 can limit lateral sliding, and the snap-fit ​​setting of the connecting piece 230 and the opening groove 270 can limit axial sliding, which greatly ensures the stability of the connection.

[0019] Example 2 Please see Figure 1 A biting edge 140 is fixedly connected to one side of the inner cavity of the jaw 130, and the biting edge 140 is set at a 45-degree angle with the jaw 130. Two jaw handles 110 are arranged vertically, and a shaft 150 is movably connected between the two jaw handles 110. Two jaw heads 120 are arranged horizontally. The inner contour of the jaw 130 matches the outer contour of a conventional hexagonal bolt and can fit against the side of the hexagonal bolt, with the fitting surfaces forming a 120-degree angle.

[0020] The jaws 130 have a 45-degree angle between their inner edge 140 and the jaws 130. This inclined structure generates a lateral force when pressure is applied, effectively pressing the edges of the female and male thread washers 210 and 220, preventing them from slipping or lifting outwards during compression. This enhances positioning accuracy and clamping reliability during operation. Two jaw handles 110 are vertically distributed and hinged together by a shaft 150. This layout conforms to human hand grip habits, allowing the operator to complete the clamping action with one hand. The inner contour of the jaws 130 matches the outer contour of a standard hexagonal bolt, and their mating surfaces form a 120-degree angle, which corresponds precisely to the geometric angle between two adjacent planes of the hexagonal bolt. This allows the jaws 130 to fully conform to all four sides of the hexagonal bolt, achieving multi-point contact and even pressure transmission. Since the jaw heads 120 are horizontally distributed, the jaws 130 can directly insert the assembled bolt and its female thread washer 210 from the outside. The 220 buckle gasket eliminates the need to remove existing nuts or loosen flange connections, completely avoiding major safety hazards such as flammable medium leakage and system shutdown caused by bolt removal.

[0021] Example 3 Please see Figures 2-5 The jaws 130 contact the female thread washer 210 and the male thread washer 220. The sides of the female thread washer 210 and the male thread washer 220 are made of copper alloy and have a tapered design. The width of the female thread washer 210 and the male thread washer 220 matches the axial width of the hexagonal bolt. The female thread washer 210 and the male thread washer 220 are attached to the surface of the hexagonal bolt. One end of the fixing piece 240 extends into the inner cavity of the mating groove 260 and is mated with the inner cavity of the mating groove 260. One end of the connecting piece 230 passes through the inner cavity of the opening groove 270 and is movably connected with the inner cavity of the opening groove 270. One end of the connecting piece 230 contacts the female thread washer 210.

[0022] Both the female and female threaded gaskets 210 and 220 are made of copper alloy, possessing excellent conductivity, oxidation resistance, and mechanical strength. Their width matches the axial width of the hexagonal bolt, ensuring complete coverage of the bolt end face and maximizing the metal-to-metal contact area. When pressure is applied by the mounting clamp 100, the female and female threaded gaskets 210 and 220 adhere tightly to the hexagonal bolt surface, forming a stable electrical path and effectively controlling the transition resistance between flanges. Both the female and female threaded gaskets 210 and 220 feature a tapered side design, gradually thinning from 2mm onwards. This design ensures that the female threaded gasket... When subjected to pressure, the female gasket 210 and the female gasket 220 are more likely to bend and deform evenly along the arc edge of the bolt, avoiding cracks or breaks caused by rigid bending. The gradually thinning edge can also enhance the sealing performance with the flange end face and reduce the intrusion of corrosive media. One end of the fixing piece 240 extends into the inner cavity of the mating groove 260 and fits with it to form a locking fit between the female gasket 210 and the female gasket 220. At the same time, one end of the connecting piece 230 passes through the opening groove 270 and bends in the opposite direction to contact and lock with the outer surface of the female gasket 210, thereby forming a reverse locking, which ensures the stability of the jumper wire 200 after installation.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
