Description
Technical field
The utility model relates to elevator technical field of construction, is specifically related to elevator job site fast and reliable grounding connection frock.
Background technology
Elevator is a kind of special equipment, and elevator is widely used in the buildings such as market, office building, house, and the electrical equipment ground connection quality of elevator construction is used elevator safely to the people undoubtedly and played vital effect.The designed reliability of elevator job site fast and reliable grounding connection frock determines the safety of elevator use, if elevator job site fast and reliable grounding connection Fixture Design is unreliable, take advantage of people's part that leak current fault occurs at elevator, elevator electrical equipment earthing device can not effectively use, and easily produces security incident and affects the safe handling of elevator.
In most elevator job site, the electrical equipment ground connection employing of elevator is connected on the earth terminal of building temporarily, and this installation method, the poor stability of installation quality, the quality of quality depends on the height of the technical merit of workman.
Summary of the invention
The purpose of this utility model is the elevator job site fast and reliable grounding connection frock providing a kind of structure simple, easy to operate, and it can solve the installation difficult problem existed in background technology.
For achieving the above object, the technical solution of the utility model, it comprises U-shaped support, stay bolt, pressure strip, and described U-shaped pedestal upper end and middle part are all provided with screw; Described stay bolt lower end is provided with screwed hole; Described stay bolt is connected with U-shaped support by U-shaped pedestal upper end screw; Described pressure strip upper end connecting rod is provided with screw thread and is connected with stay bolt lower end screwed hole; Described lag bolt is connected with U-shaped support by U-shaped mid-stent screw; Described ground connection divides terminal to be connected with U-shaped support by lag bolt; Described earth bus is connected with U-shaped support by pressure strip.
In technique scheme, described nut one is connected on stay bolt; Described nut two is connected on lag bolt.
Effect of the present utility model is: structure is simple, easy to operate, reliable clamping, and the good stability of elevator electrical equipment ground connection quality, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model elevator job site fast and reliable grounding connection frock.
Attached number in the figure is respectively: 1, U-shaped support, 2, stay bolt, 2 ', lag bolt, 3, ground connection divides terminal, 4, earth bus, 5, nut one, 5 ', nut two, 6, pressure strip.
Embodiment
Below in conjunction with accompanying drawing, the utility model elevator job site fast and reliable grounding connection frock is described further.
As seen from Figure 1, the utility model it comprise U-shaped support, stay bolt, pressure strip, described U-shaped pedestal upper end and middle part are all provided with screw; Described stay bolt lower end is provided with screwed hole; Described stay bolt is connected with U-shaped support by U-shaped pedestal upper end screw; Described pressure strip upper end connecting rod is provided with screw thread and is connected with stay bolt lower end screwed hole; Described lag bolt is connected with U-shaped support by U-shaped mid-stent screw; Described ground connection divides terminal to be connected with U-shaped support by lag bolt; Described earth bus is connected with U-shaped support by pressure strip.
Using method of the present utility model is: the top first nut one (5) being screwed to stay bolt (2), stay bolt (2) is screwed to the position of stay bolt (2) length half by U-shaped support (1) upper end screw, pressure strip (6) upper end connecting rod is connected with stay bolt (2) lower end screwed hole, stay bolt (2) is down rotated, pressure strip (6) is made to compress earth bus (4) until apply 50N pretightning force, stop nut one (5) is screwed to is close to U-shaped support (1), the ground connection of ground connection each is needed to divide terminal (3) to be connected on lag bolt (2 '), lag bolt (2 ') compression ground connection is made to divide terminal (3) until apply 50N pretightning force, stop nut two (5 ') is screwed to be close on U-shaped support (1), each earth terminal has connected.
In the present embodiment, described nut one (5) is connected on stay bolt (2), and described nut two (5 ') is connected on lag bolt (2 '), does not loosen when this can ensure that each earth terminal uses.
