Abstract

The utility model relates to a multi-function jointing clamp for high-altitude, which belongs to a special jointing tool for electrical equipment detection, and is particularly suitable for detection and jointing of high-altitude equipment from the ground. The utility model is mainly characterized in that the utility model is provided with a fixed and a movable jaws, wherein, the movable jaw moves following a movable pulley, and a steel cable for connecting the movable and a fixed pulleys is controlled by a special push and pull mechanism for hoisting a long rod from the ground; the special push and pull mechanism is provided with a locking mechanism to ensure the clamping force of the jaws. Mounting holes of the fixed and the movable jaws are inclined and long, which can cause the jaws to be clamped and to simultaneously produce transverse friction motion so as to overcome an oxide film at the jointing position. The utility model solves the problem of need of climb at the time of high-altitude detection and jointing operation, and need of manually overcoming the oxide film. The jointing clamp has the advantages of simple structure, convenient operation, one clamp with multifunction, can clamp wires and simultaneously remove the oxide film, and can be suitable for jointing requirements of different angles.

Description

Multi-functional high-altitude wiring pincers

The utility model relates to the wiring specific purpose tool that detects electric equipment, is the detection wiring specific purpose tool that is particularly suitable for the high-altitude electric equipment.

At present, there is the wiring position of a lot of detected electric equipments very high apart from ground, operating personnel generally will climb to the equipment under test work high above the ground of getting on during wiring in test, and the oxide-film that overcomes wiring position during operation also can only the people for rocking disposal, operation is not only loaded down with trivial details but also dangerous like this, and operating efficiency is also low.

The purpose of this utility model is exactly to overcome the shortcoming that above-mentioned prior art exists, and providing a kind of can clamp at the multi-functional high-altitude wiring that terrestrial operation is tested the wiring special use to altitude plant, and this jointing clamp also can overcome the oxide-film of line position simultaneously.

The purpose of this utility model can realize in the following manner.

The jointing clamp jaw is designed to decide jaw 4 and movable clamp port 11, decide jaw 4 and be fixed on the top of slideway 15 through its support 3, movable clamp port 11 fixes as one with movable pulley 13 by its support 12, fixed pulley 2 is fixed on slideway support 1 upper end, steel wire rope 16 1 ends are fixed on to be decided on the jaw support 3, the other end twines movable pulley 13, fixed pulley 2 successively, be connected again on the retaining mechanism 7 of special push-pull bar, there is the return mechanism 14 that is connected with movable clamp port support 12 lower end of slideway 15, and movable clamp port, the installing hole of deciding jaw are oblique slotted holes.

Major advantage of the present utility model is: 1. the mode that adopts fixed, movable clamp port and movable pulley to drive jaw not only is implemented in the wiring test jobs that the high-altitude just can be operated in ground, and this mode can make opening apart from very big of upper and lower jaw, also be easy to clamp wiring position even the act bar rocks, and enough clamping forces are arranged; 2. when adopting each 2 jaw, its installing hole is the opposite oblique slotted hole of both direction, some strength that transmits from the jaw installation shaft when then clamping object, make two jaws on wiring position, produce rightabout fricting movement, the jaw material hardness is higher than the wiring position material in addition, so can effectively overcome the oxide-film of wiring position, it is good to make it contact; 3. in the push-and-pull special pole retaining mechanism is arranged, guaranteed that there are enough lasting clamping forces jointing clamp butted line position, to satisfy the operation needs; 4. the angle of the slideway of jointing clamp and its support can change between 0～90 °, has adapted to the wiring needs of different angles wiring positions, and is practical.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model overall construction drawing

Fig. 2 is the A-A cutaway view of Fig. 1

Fig. 3, Fig. 4, Fig. 5 are respectively front view, right view, the left views of special push-pull bar, among the figure the 23, the 24th, and coupling spindle

Fig. 6 has opposite tiltedly 2 the jaw structural representations of long installing hole of direction

In the present embodiment, the special push-pull bar is made of retaining mechanism 7 and connected push-pull mechanism 10, the two outside is with the conduit 5 that is fixed on the slideway support 1, porose tooth 20 and gathering sill 25 on the conduit 5, retaining mechanism 7 is provided with energy-stored spring 6, and there are ratchet 9 and ratchet support 8 in its below, the root of ratchet has return spring 26, the connecting hole 22 of push-pull mechanism 10 on ratchet support 8 is slotted holes, and return mechanism 14 is made of disc spring, is connected with movable clamp port support 12 through stay cord.

Push-pull mechanism 10 is that a hollow stem is connected on the retaining mechanism 7, and when straining or loosening hollow stem 10, interlock locking mechanism 7 can drive movable pulleys 13 through steel wire ropes 16 make movable clamp port 11 to deciding jaw 4 closures or opening.During use, at 10 times extension bars of hollow stem, jointing clamp is lifted, hang on the wiring position deciding jaw 4 earlier, pulling stock movable clamp port 11 will to decide jaw 4 directions move to moving, decide jaw and be clipped on the wiring position, while ratchet 9 patchhole teeth 20 power of will pressing from both sides is pinned automatically.Otherwise the promotion stock, ratchet 9 is just opened, and jaw also unclamps gets back to original position.

In addition, moving, decide jaw can be each 1, also can be that each is more than 2 or 2, moving, decide jaw in the present embodiment is each 2, installing hole 18,18 ＇ of two jaws are oblique slotted holes angled with the vertical direction of jaw, and the incline direction of two oblique slotted holes is opposite, is contained on the jaw support by jaw installation shaft 19, also has compression spring 17 at the jaw root.Jaw is when clamping object, because the effect of oblique microscler installing hole 18,18 ＇, the strength that jaw installation shaft 19 is transmitted resolves into two parts, part strength makes jaw and wiring position produce clamping force, another part strength makes two jaws produce rightabout fricting movement on wiring position, the high rigidity of jaw material in addition, thereby can overcome the oxide-film of wiring position effectively, realized that jointing clamp is when clamping object, can overcome top oxide-film again, the multi-functional innovation of pincers.

Also have, slideway 15 and slideway support 1 are connected by hinge, make slideway 15 rotate 0～90 ° with respect to slideway support 1, adapt to the wiring needs of different angles wiring positions.
