Abstract

The invention provides an earth wire clip for a transformer substation and belongs to a wire clip for installing an earth wire in a transformer substation. The earth wire clip consists of a hook-shaped connecting piece (2) and a fork-shaped core block (3); a connecting terminal (11) connecting with the earth wire is arranged on the hook-shaped connecting piece; and the hook head part of the hook-shaped connecting piece is provided with an arc-shaped section which is matched with the arc-shaped surface of the fork-shaped core block to form a circular arc jaw of a clamping lead wire (1). The inner edge surface of a first gear shaft center hole is provided with internal screw threads which are matched with the external screw threads of a screw rod (7); and the end part of the screw rod is connected with the fork-shaped core block. One end of the firs gear shaft and one end of a second gear shaft are respectively bevel gears, and the two bevel gears are meshed with each other. The other end of the second gear shaft is connected with a sleeve (9); and the sleeve is connected with an operating bar (10). By the adoption of the earth wire clip, the earth wire can be quickly connected with the lead wire, thus, the earth wire clip is suitable for various lead wires with various different angles and thicknesses, and has the characteristics of simplicity and reliability in operation, time saving, manpower saving and high efficiency.

Description

The transformer substation grounding wire wire clamp
Technical field
The present invention relates to worker's accessory in a kind of power industry field, particularly belong to a kind of wire clamp that is used for installing earth connection in the transformer station.
Background technology
At present, the line conductor vertical arrangement of part 220kV transformer station, and the line footpath is very thick, and when line maintenance required at line side installing earth connection, operation is difficulty very.Perhaps use the live line working overhead vehicle to operate, perhaps, the line side ground connection disconnecting link that closes earlier helps to load onto earth connection by the maintainer again.The program complexity, potential safety hazard is many, particularly in the outlet near road, carries out the ground connection operation because of no operation range can not use charged aerial lift vehicle.Existing a kind of hook-type ground connection the end of a thread owing to dehiscing little and can't regulating, causes ground connection head and lead contact-making surface little, comes off easily, makes the operating personnel may be subjected to faradic injury.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of novel transformer substation grounding wire wire clamp, to reach convenient, safe and reliable, the easy to operation purpose of earth connection installing.
Transformer substation grounding wire wire clamp provided by the present invention, it is characterized in that, constitute by hook-type connector and fork-shaped pellet, the splicing ear that connects earth connection is arranged on the hook-type connector, the gib head of hook-type connector partly has segmental arc, cooperate with the arcwall face of fork-shaped pellet, constitute the circular arc jaw of clamping lead; The hook portion of hook-type connector has shaft clip, and built-in first gear shaft, first gear shaft are hollow shaft, and the inner edge surface of centre bore is established internal thread, cooperates with the leading screw external screw thread; The leading screw end is connected with the fork-shaped pellet; Second gear shaft is installed on the axle sleeve of link block, fixedlys connected between link block and the hook-type connector; One end of first gear shaft and second gear shaft is respectively bevel gear, and both are meshing with each other; The other end joint sleeve of second gear shaft, sleeve pipe is connected with action bars.
Transformer substation grounding wire wire clamp provided by the present invention, earth connection is connected in the splicing ear on the hook-type connector, action bars is connected with sleeve pipe, can hand the height that develops simultaneously during work, the hook-type connector is ridden against on the lead, rotary manipulation bar then, by second gear shaft, the transmission of bevel gear between first gear shaft, and first the screw thread transmission between gear shaft and the leading screw, driving the fork-shaped pellet and move, the jaw that makes it to constitute with the hook-type connector tightly clamps lead, being grounded line is connected with the quick of lead, applicable to various angles, all kinds of leads that thickness is different have easy and simple to handle reliably, save time, laborsaving, the characteristics that efficient is high.

Embodiment
As shown in Figure 1 and Figure 2, transformer substation grounding wire wire clamp provided by the present invention is made of the circular arc jaw of clamping lead 1 hook-type connector 2 and fork-shaped pellet 3.Through hole or screwed hole are arranged, as the splicing ear 11 that connects earth connection on the hook-type connector.Fork-shaped pellet 3 is connected with leading screw 7 ends.The hook portion of hook-type connector forms the shaft clip 4 that swells when casting, built-in first gear shaft 5, and as shown in figure 11, first gear shaft 5 is a hollow shaft, the inner edge surface of centre bore is established internal thread, cooperates with leading screw 7 external screw threads.Second gear shaft 6 is installed on the axle sleeve of link block 8, fixedlys connected between link block and the hook-type connector.Obviously, an end of first gear shaft and second gear shaft is respectively bevel gear, and both are meshing with each other.The other end joint sleeve 9 of second gear shaft, sleeve pipe then are connected with action bars 10.
Fig. 3~shown in Figure 10, for constituting the part drawing of hook-type connector of the present invention, fork-shaped pellet, link block, CONSTRUCTED SPECIFICATION is high-visible, so do not do too much explanation.
The multiple mode that is connected with of sleeve pipe 9 and action bars 10, key cooperates with keyway as using, conical surface friction cooperation etc., all realizations easily.In the present embodiment, the sleeve pipe flare has draw-in groove 9-1 on the sidewall, cooperates with the pin 10-1 of action bars 10 ends, and it is firm to play connection, prevents the purpose that comes off.
With the matching used action bars of the present invention, preferably specialized designs is made, and also can select rod, the insulating bar of merogenesis combination for use, and according to scene height needs, assembling is used flexibly.
