Abstract
The utility model discloses a ground wire clamp which comprises a type E chuck and an operating lever, wherein the type E chuck comprises a column, an upper crossbeam, a lower crossbeam and a movable clamping plate. The upper crossbeam and the lower crossbeam are respectively fixed to the upper and lower ends of the column, and one ends of the movable clamping plate is slidingly connected to the column and is liftable along the column. The lower crossbeam is provided with a vertical screwed hole, and the top end of an operating lever is connected with a screw matching with the screwed hole. The top end of the screw is connected with the lower surface of the movable clamping plate after passing through the screwed hole, and a clamping area is arranged between the upper surface of the movable clamping plate and the upper crossbeam. The outer end portion of the upper crossbeam is provided with a downwardly extending hook portion, and the distance between the hook portion and the column is slightly greater than the length of the movable clamping plate. The length of the hook portion is 0.3-0.5 times of the distance between the upper crossbeam and the lower crossbeam. The hook portion prevent falling off of the type E chuck from a device due to rotation of the operation rod, and the work efficiency and safety coefficient are improved.
Description
Technical field
The utility model relates to electric power facility field, is specifically related to a kind of earthing clamp.
Background technology
In electric power system, for preventing surprisingly on power failure equipments or circuit occurring must connecting earth connection on equipment or circuit by electric current, so that the unexpected electric current occurring is introduced to the earth, thereby ensure staff's personal safety.Earth connection is by earthing clamp and equipment or connection, the earthing clamp of the unified dispensing of Jiangsu Power Company is at present made up of E type chuck and action bars, E type chuck upper, sill is fixedly connected with column respectively, on middle cross beam and column, be respectively equipped with the slide rail of coupling, chute, pass through slide rail, chute can be along column up-down, sill is provided with vertical screwed hole, action bars top is connected with the screw rod mating with screwed hole, screw tip is connected with the lower surface of ambulatory splint through after screwed hole, it between ambulatory splint upper surface and entablature, is clamp area, when earth connection is installed, staff is suspended on entablature on equipment or circuit, rotating operation bar, by screw rod, ambulatory splint is upwards pushed up, until ambulatory splint and entablature clamp equipment or circuit, in installation process, between E type chuck entablature and equipment or circuit, only has the frictional force producing because of Action of Gravity Field, when the power of rotating action bars as staff is greater than frictional force, E type chuck also can be along with action bars rotates, be easy to come off from equipment or circuit, staff must hang entablature again, in the time that clamp area spacing is very little, again the difficulty hanging is large, often need reverse rotation action bars to expand clamp area, in the installation process of an earth connection, often to repeat for several times, earth connection installment work on average will be spent about 8 minutes, physical demands to staff is large, efficiency is low, in addition, when equipment or circuit are during than comparatively dense, near charged equipment or circuit E type chuck comes off and easily touches, E type chuck and the earth connection being connected on E type chuck are all good conductors, are easy to occur electric shock accidents, coefficient of safety is low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of earthing clamp, can solve and between existing earthing clamp entablature and equipment or circuit, only have the frictional force producing because of Action of Gravity Field, chuck is easy to come off, and causes the low and low problem of coefficient of safety of installment work efficiency.
The utility model is achieved through the following technical solutions:
A kind of earthing clamp, comprise E type chuck and action bars, described E type chuck is by column, entablature, sill and ambulatory splint composition, described entablature, sill is fixedly connected on respectively on column, lower two ends, described ambulatory splint one end is slidably connected to column, can be along column up-down, described sill is provided with vertical screwed hole, described action bars top is connected with the screw rod mating with screwed hole, described screw tip is connected with the lower surface of ambulatory splint through after screwed hole, between described ambulatory splint upper surface and entablature, it is clamp area, the outer end of described entablature is provided with the hook portion to downward-extension, the spacing of described hook portion and column is slightly larger than the length of ambulatory splint, the length of described hook portion is entablature and sill spacing 0.3 ~ 0.5 times.
The material of described hook portion is identical with E type chuck entablature, and described hook portion and entablature are by welding or bonding or integrally casting moulding or be threaded or the mode that clamps connects as one.
Described column is provided with vertical slide rail, and described ambulatory splint one end is provided with the chute mating with slide rail.
Column, entablature, the sill of described E type chuck are integrated casting.
The utility model advantage is compared with prior art:
One, by being set, hook portion avoid E type chuck because coming off from equipment or circuit with action bars rotation, significantly reduce the difficulty that earthing clamp is installed, increase work efficiency, avoided touching because E type chuck comes off the potential safety hazard that other charging equipments or circuit bring simultaneously by mistake, improve coefficient of safety;
Two, simple in structure, with low cost, implement convenient, effect is remarkable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
