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 is a kind of L type block type conductor termination ground clamp.
Background technology
The conductor termination ground clamp is a kind of safety appliance that is used for the transmission pressure temporary short-circuit ground connection that has a power failure, and its effect is to the high voltage electricity transmission conductive wire interruption maintenance time, prevents that unexpected incoming call or contiguous high voltage alive equipment from producing the harm of induced voltage to human body.At present the earthing clamp that uses of each grid company mainly contains spiral, duck tongue type, flat and impacting type.Duck tongue type is because the chucking power that produces during clamping lead balance relatively, and relatively is convenient to operation and is widely used, and its primary structure is made up of a hook, two tongue pieces, action bars, two tension springs; Action bars is connected with hook, the bend that hook has two clamping parts and connects clamping part, and two tongue piece positioned opposite and one of which end flexibly connect with hook two clamping parts respectively; The other end stretches in the groove that bend is provided with, and forms splay folder mouthful, and the earthing clamp of this structure is when being used for hanging wire; Lead begins to make two tongue pieces to rotate along different directions when getting into the corresponding position of Jia Kou and its size, until two tongue pieces since tension spring produce and elastic force linked up with can be fixed on the lead; Promptly accomplish the hanging wire process, still, hung up properly the place that folds that the back lead is positioned at two tongue pieces; Be the top of herringbone,, even under wind, also can produce conductor galloping owing to lead is in the outdoor environment of strong wind, heavy rain often; Hook is overturn, cause hook to come off, cause temporary short-circuit to lose efficacy from lead; The maintainer is produced serious personal injury, so there is great potential safety hazard.And because job site center line footpath size is different, when using duck tongue type, it is different that different line footpath leads is positioned at the position of tongue piece.The major diameter lead is positioned at the bottom of tongue piece, i.e. the bottom of Eight characters clevis mouth, and easy landing phenomenon appears in lead.In addition, spiral earthing clamp also has certain use amount because its clamping lead is more firm in industry; Spiral earthing clamp comprises chuck, horizontal locking bar and action bars, and chuck is the U type of horizontal arrangement, forms the folder mouth of a horizontal direction opening; Horizontal locking bar is contained in the folder mouthful and with action bars and is connected to become the connector of T type, and the base of action bars and chuck is through being threaded, thereby; Through the rotary manipulation bar,, just can drive the rise and fall of horizontal clamping bar in the folder mouth because action bars and horizontal locking bar are connected as a single entity; Thereby clamp or unclasp lead, but, clamp lead through threaded adjusting because the folder mouth has certain aperture; Action bars need be twisted a lot of number of turns just can make horizontal locking bar with lead locking in the folder mouth, and it is extremely inconvenient to operate.
Summary of the invention
The purpose of this invention is to provide a kind of while simple to operate can prevent that lead from coming off from wire clamp L type block type conductor termination ground clamp.
The present invention achieves the above object through following technical scheme: L type block type conductor termination ground clamp; Comprise hook, an action bars that has the earth lead end; The bend that said hook comprises left clamping part, right clamping part and connects said left clamping part and right clamping part; Be connected with two rotating tongue pieces in said left clamping part, the right clamping part respectively and lay respectively at two tension springs between this tongue piece and clamping part, said pair of tongue piece positioned opposite is formed for clamping the splay folder mouth of lead, and said right clamping part edge extends a horizontal ledge; Said horizontal ledge and said action bars are rotatably connected; The termination of said action bars is connected with horizontal locking bar, is provided with the fore shaft that matches with this horizontal locking bar in the said hook, and this earthing clamp comprises that also one can be consolidated the catch means in said hook fore shaft with said Horizontal lock lever lock; Said catch means comprises that said fore shaft top, edge is vertically set on the groove in the left clamping part; The top of said groove connects an end of spring, and the other end of this spring is connecting spin, and the bottom of said groove is provided with the baffle plate of the band through hole that blocks said spin; The part of said spin protrudes from the through hole of baffle plate and extends in the said fore shaft, and the termination of said horizontal locking bar is provided with the ball hole that matches with spin.
Between said horizontal ledge and the horizontal locking bar through being threaded.
Said horizontal locking bar mid portion is for being arranged to the inclined-plane.
Beneficial effect of the present invention is:
Owing to be rotatably connected and increase by a horizontal locking bar in the termination of action bars at action bars and hook; Have the fore shaft that matches with horizontal locking bar on the hook, lead is after the Eight characters clevis mouth that is formed by two tongue pieces is clamped lead, and the rotary manipulation bar makes horizontal locking bar get into fore shaft; Just can make the Horizontal lock pole spacing below lead; Prevent that lead from mouthful deviating from from folder, it is very convenient to operate, and between hook and horizontal locking bar, also is provided with catch means simultaneously; Horizontal locking bar is securely fixed in the left clamping part of hook; Effectively prevent to cause horizontal locking bar and hook to relatively rotate because of strong wind atmosphere or conductor galloping, improved the anticreep effect, can horizontal locking bar and lead corresponding section be arranged to the inclined-plane in addition; Produce on the contrary when making the downward play of lead and make horizontal guide produce the thrust to the left clamping part fore shaft motion of hook, the anticreep performance of wire clamp obtains further perfect.
