Abstract
The utility model provides a portable electric cable clamp of a short circuit grounding wire. The electric cable clamp is characterized in that a motion clamping mechanism is internally provided with a pawl, the pawl and a screw rod keep a screw thread drive relationship, the screw rod is fixedly connected with a motor, the pawl is connected with a disjointed spring in a hanging and pulling mechanism through a cable brake, a clamp block in the motion clamping mechanism is matched with a pawl mechanism in a slipping way, and the clamp block is in touch with a trip spring and a return spring. The electric cable clamp has the following advantage: the electric cable clamp electrically clamps a high-tension cable with the following characteristics: the physical strength thereof is more than 50kg when clamping a high-tension cable; and the security thereof is better than that of a spring type grounding wire. The electric cable clamp can carry or be provided with electronic equipment. The portable electric cable clamp judges the position of a conducting wire with an optoelectronic switch and clamps the high-tension cable with the drive of the motor, thereby obviously improving the reliability and the operation conveniences for clamping the conducting wire. When the grounding wire is loosened, a paw which clamps the conducting wire is firstly returned and loosened and then separated from the conducting wire, so that the conducting wire can not be scratched.
Description
Technical field
The utility model relates to a kind of electronic wire clamp of portable short-circuit grounding wire, belong to line technology field power ground.
Background technology
Similar products mainly is with the tight high-voltage line of spring clamping connection ground wire in the market, and shortcoming is that the strength of clamping high-voltage line is not enough, can not load electronic equipment on earth connection, and bigger than normal with the contact resistance of lead.
Summary of the invention
The utility model proposes a kind of electronic wire clamp of portable short-circuit grounding wire, be intended to overcome the above-mentioned defective of existing in prior technology, it is big, safe and reliable to have the strength that clamps high-voltage line.
Earth terminal is preferentially pointed out the connection prompt facility: product just can be worked after having only the earth connection tower termination energising line of force tower of product, does like this and can avoid operating personnel's misoperation.
Technical solution of the present utility model: its structure is in the motion clamp system ratchet to be housed, ratchet and screw mandrel keep the screw thread drive connection, screw mandrel and motor are fixedly connected on together, ratchet and extension hang and draw back in-house disengagement spring and stop by line and connect, clamp in the motion clamp system and clip claw mechanism keep being slidingly matched, and clamp touches mutually with trip spring, return spring.
Advantage of the present utility model: this product is as follows with electric power formula clamping mode clamping high-voltage line characteristics: strength is more than 50kg when clamping high-voltage line, and fail safe is better than the spring earth connection.Can carry or load electronic equipment.Used optoelectronic switch to judge lead location, motor driven clamping mode then, the reliability and the operation convenience of clamping wire are significantly improved.Earth connection claw of clamping wire when unclamping is that first return unclamps, and is leaving lead then.Therefore can not scratch lead.
Description of drawings
Accompanying drawing 1 is the structural representation of the electronic wire clamp of portable short-circuit grounding wire.
Accompanying drawing 2 is end views of Fig. 1.
Among the figure 1 hangs to hang to draw back mechanism, the 2nd, throws off spring, the 3rd, and line stops, the 4th, ratchet, the 5th, motion clamp system, the 6th, screw mandrel, the 7th, return spring, the 8th, clamp, the 9th, motor, the 10th, clip claw mechanism, the 11st, trip spring, the 13rd, earthing strip, the 14th, battery, the 15th, control circuit, the 16th, photoelectricity electric switch, the 17th, lead, the 18th, lifting rope, the 19th, earth connection tower end.
Embodiment
The contrast accompanying drawing, its structure is to hang to hang to draw back mechanism 1, motion clamp system 5, motor 9, clip claw mechanism 10, earthing strip 13, battery 14, control circuit 15 admittedly for fixing on the casing, ratchet 4 is housed in the motion clamp system 5, ratchet 4 keeps the screw thread drive connection with screw mandrel 6, screw mandrel 6 is fixedly connected on together with motor 9, ratchet 4 hangs the disengagement spring 2 that draws back in the mechanism 1 and stops by line and 3 connect with hanging, clamp 8 keeps being slidingly matched with clip claw mechanism 10 in the motion clamp system 5, and clamp 8 touches mutually with trip spring 11, return spring 7.
Described extension hang draw back mechanism 1 be used to connect lifting rope, when manual release apparatus will with more than the 20kg----the line----conduction between the ratchet of stopping is finished from the task of lead disengagement product by the disengagement spring to upper pulling force.Vital part is to throw off spring.Be fixed on the casing, in be equipped with and throw off spring 2, lifting rope 18 is bundled on it.
Throw off spring 2, when spring tension during greater than 20kg, spring begins to shrink, and drives steel wire and the ratchet of line in stopping, and makes ratchet and screw mandrel break away from engagement, finishes return and restores.Being fixed on to hang to hang and drawing back mechanism 1 inside, is to hang to hang the inner body that draws back mechanism 1.
Line stops 3, is used to throw off the connection between spring 2 and the ratchet 4.Be fixed on to hang to hang and draw back between mechanism 1 and the ratchet 4.
Ratchet 4 is used to keep or the engagement of disengaging and screw mandrel, and transmits the thrust that screw mandrel produces.Be contained in the motion clamp system 5, stopping with line 3 is connected, and is that motion clamp system 5 inner bodies and screw mandrel 6 keep the screw thread drive connections.
Motion clamp system 5, under the driving of motor, screw mandrel drives clamp and moves downward, and makes the jaw mouth dwindle clamping wire.Under the motor inversion driving, screw mandrel drives clamp and moves upward, and jaw mouth spreading is finished thrown off the product task on high-voltage line.When motor reverses, finish the task of throwing off product from lead.And mechanism's return is restored.Be fixed on the casing, in ratchet 4 is housed.
Screw mandrel 6 is used for the actuating force transmission between motor and the ratchet.Be fixed together with motor 9, hold the screw thread drive connection with ratchet 4.
Return spring 7 is used for clamp 8 returns, and makes whole clamp system return.
Clamp 8, the part that jaw is moved.
Control circuit board 15 is used to realize the machinery control of product and shake the control open and close.
Whether photoelectricity electric switch 16 is used to detect lead (high-voltage line) at shown position.
Lead 17, the power high voltage line.It is the object that this product clamps.
Earth connection tower end 19: be used to control the work opening and closing of product.The installation site is on the power line tower, and is connected with power line tower ground wire.
Operation principle
Clamping process: detect high-voltage line to the equipment jaw position by optoelectronic switch, if no motor does not change.If there is the motor drives screw mandrel to start, clamp moves downward, and jaw clamps high-voltage line, and the motor stall is also finished mechanical action.
Manual release process: with the above strength pulling lifting rope of 20kg, throw off length of spring compressed, the pulls wire steel wire of stopping, ratchet and screw mandrel break away from, return spring makes the entire mechanism return restore automatic release process: the motor backward rotation, the clamp return that makes progress, the jaw spreading unclamps lead, and the entire mechanism return restores.
