Abstract
The invention relates to an L-shaped baffle block type lead end grounding clamp, which comprises a hanger provided with a grounding lead end and an operating rod, wherein the hanger comprises a left clamping part and a right clamping part, the left clamping part and the right clamping are internally connected with two rotatable tongue pieces, a horizontal boss extends out of the edge of the right clamping part, the horizontal boss is rotatably connected with the operating rod, the end of the operating rod is connected with a horizontal lock rod, and the hanger is internally provided with a lock port matched with the horizontal lock rod. The L-shaped baffle block type lead end grounding clamp further comprises a locking device capable of locking the horizontal lock rod in the lock port of the hanger. After a lead is clamped by a splayed clamping port formed by the two tongue pieces, the operating rod is rotated to make the horizontal rod enter the lock port, and the horizontal lock rod is blocked under the lead so as to prevent the lead from dropping from the clamping port. The L-shaped baffle block type lead end grounding clamp is easy to operate. Meanwhile, a locking device is arranged between the hanger and the horizontal lock rod, so that the phenomenon that the horizontal rod rotates relative to the hanger in the strong wind environment is eliminated, and the anti-dropping effect is enhanced.
Description
Technical field
The present invention relates to a kind of earthing clamp, specifically a kind of L-type block type wire end earthing clamp.
Background technology
Wire end earthing clamp is a kind of for by the safety appliance of transmission pressure temporary short-circuit ground connection having a power failure, and its effect is when to high voltage electricity transmission conductive wire interruption maintenance, prevents that suddenly incoming call or contiguous high voltage alive equipment produce the harm of induced voltage to human body.That the earthing clamp that current each grid company is used mainly contains is spiral, duck tongue type, flat and impacting type.The chucking power that duck tongue type produces during due to clamping wires is balance relatively, and compare convenient operation and be widely used, its primary structure is by a hook, two tongue pieces, action bars, two tension spring compositions, action bars is connected with hook, hook has two clamping parts and connects the bend of clamping part, two tongue piece positioned opposite and its one end are flexibly connected with hook two clamping parts respectively, the other end stretches in the groove that bend is provided with, form splay jaws, the earthing clamp of this structure is when for hanging wire, wire is in the time entering jaws and its corresponding position of size, start to make two tongue pieces to rotate along different directions, until two tongue pieces make elastic force hook can be fixed on wire because tension spring produces, completed hanging wire process, but, hang up properly the place that folds that rear wire is positioned at two tongue pieces, it is the top of herringbone, because wire is in strong wind often, in the outdoor environment of heavy rain, even under wind-force effect, also can produce conductor galloping, hook is overturn, cause hook to come off from wire, cause temporary short-circuit to lose efficacy, maintainer is produced to serious personal injury, so there is great potential safety hazard.And because wire diameter size in job site is different, while using duck tongue type, different wire diameter wires are positioned at the position difference of tongue piece.Major diameter wire is positioned at the bottom of tongue piece, i.e. the bottom of splayed jaws, and there is easy landing phenomenon in wire.In addition, spiral earthing clamp is because its clamping wires is more firm, also there is certain use amount industrial, spiral earthing clamp comprises chuck, horizontal locking bar and action bars, chuck is the U-shaped of horizontal arrangement, form the jaws of a horizontal direction opening, horizontal locking bar is contained in jaws and is connected to become T-shaped connector with action bars, the base of action bars and chuck is threaded connection, thereby, by rotation action bars, because action bars and horizontal locking bar are connected as a single entity, just can drive the rise and fall of horizontal clamping bar in jaws, thereby clamp or unclasp wire, but because jaws has certain aperture, clamp wire by threaded adjusting, action bars need be twisted a lot of number of turns just can make horizontal locking bar that wire is locked in jaws, operate extremely inconvenient.
Summary of the invention
The object of this invention is to provide the L-type block type wire end earthing clamp that a kind of while simple to operate can prevent that wire from coming off from wire clamp.
The present invention achieves the above object by the following technical programs: L-type block type wire end earthing clamp, comprise a hook with earth lead end, action bars, described hook comprises left clamping part, right clamping part and connect the bend of described left clamping part and right clamping part, described left clamping part, in right clamping part, be connected with respectively two rotating tongue pieces and lay respectively at two tension springs between this tongue piece and clamping part, described pair of tongue piece positioned opposite is formed for clamping the splay jaws of wire, described right clamping part edge extends a horizontal ledge, described horizontal ledge and described action bars are rotatably connected, the termination of described action bars is connected with horizontal locking bar, in described hook, be provided with the fore shaft matching with this horizontal locking bar, this earthing clamp also comprises that one can be consolidated the catch means in described hook fore shaft by described Horizontal lock lever lock, described catch means comprises along described fore shaft top and is vertically set on the groove in left clamping part, one end of the top linking springs of described groove, the other end of this spring is connecting spin, the bottom of described groove is provided with the baffle plate with through hole that blocks described spin, a part for described spin protrudes from the through hole of baffle plate and extends in described fore shaft, the termination of described horizontal locking bar is provided with the ball hole matching with spin.
Between described horizontal ledge and horizontal locking bar, be threaded connection.
Described horizontal locking bar mid portion is for being arranged to inclined-plane.
Beneficial effect of the present invention is:
Owing to being rotatably connected and increasing by a horizontal locking bar in the termination of action bars at action bars and hook, on hook, have the fore shaft matching with horizontal locking bar, wire is clamped after wire in the splayed jaws being formed by two tongue pieces, rotation action bars makes horizontal locking bar enter fore shaft, just can make Horizontal lock pole spacing below wire, prevent that wire from deviating from from jaws, operate very convenient, between hook and horizontal locking bar, be also provided with catch means simultaneously, horizontal locking bar is securely fixed in the left clamping part of hook, effectively prevent from causing horizontal locking bar and hook to relatively rotate because of strong wind atmosphere or conductor galloping, improve anticreep effect, horizontal locking bar and wire corresponding section can be arranged to inclined-plane in addition, while making the downward play of wire, produce on the contrary horizontal guide is produced to the thrust of the left clamping part fore shaft motion of hook, the anticreep performance of wire clamp is further improved.
