Abstract
The invention relates to a linkage structure of a safety tong and a speed governor. The linkage structure of the safety tong and the speed governor comprises a draw rod head, a draw rod, a guide plate and a connecting piece with a hole, wherein the draw rod head is in a Z-shaped structure, a through hole is formed at the upper end of the draw rod head, the lower end pf the draw rod head is connected with the draw rod, a small hole is formed in the guide plate, the draw rod is arranged inside the guide plate in a movable mode and penetrates through the small hole, and the connecting piece is connected with the tail end of the draw rod. The linkage structure of the safety tong and the speed governor is suitable for various elevators with lower lifting structures.
Description
Technical field
The present invention relates to the elevator technology field, refer to especially the linkage structure of a kind of safety tongs and velocity limiter.
Background technology
At present, traditional elevator mostly adopts upper stretching structure, and the linkage structure of its safety tongs and velocity limiter comprises drawhead 1, pull bar 2, is arranged on guide plate 3 on vertical beam and connecting strap 4 with holes as shown in Figure 1.The length of pull bar 2 can change because of the height change of car, cannot unify size, and intermediate guide plate 3 generally is connected with vertical beam, easily rock the generation noise because pull bar 2 is long, and the general weldment that adopts of pull bar 2 and guide plate 3, the processing more complicated is brought many inconvenience.
Summary of the invention
Technical matters to be solved by this invention is: a kind of safety tongs of the elevator that is applicable to lower stretching structure and the linkage structure of velocity limiter are provided.
For addressing the above problem, the technical solution used in the present invention is: the linkage structure of a kind of safety tongs and velocity limiter, comprise drawhead, pull bar, guide plate and connecting strap with holes, and described drawhead is the Z-shaped structure, the drawhead upper end is provided with through hole, and the lower end is connected with pull bar; Be provided with aperture on described guide plate, pull bar is movably arranged in guide plate, and passes aperture; Described connecting strap is connected with the pull bar end.
Be provided with elastic ring in the aperture of described guide plate.
Described drawhead lower end is provided with fixed orifice, and pull bar one end passes fixed orifice, and fixes by nut.
The invention has the beneficial effects as follows: the linkage structure of above-mentioned safety tongs and velocity limiter, adopted the drawhead of Z-shaped structure not only to guarantee stiffness but also cancelled welding, the connection location of guide plate is changed on lower beam connection, make the pull bar contraction in length, difficult generation is rocked and noise, and processing technology is simple.

In Fig. 1: 1, drawhead, 2, pull bar, 3, guide plate, 4, connecting strap.
In Fig. 2 and 3: 1, drawhead, 2, pull bar, 3, guide plate, 4, connecting strap, 5, through hole, 6, fixed orifice, 7, nut, 8, aperture, 9, elastic ring.
The specific embodiment
Be described in further detail below by the linkage structure of specific embodiment to a kind of safety tongs of the present invention and velocity limiter.
As shown in Figures 2 and 3, the linkage structure of a kind of safety tongs and velocity limiter, comprise drawhead 1, pull bar 2, guide plate 3 and connecting strap 4 with holes, described drawhead 1 is the Z-shaped structure, drawhead 1 upper end is provided with through hole 5, the lower end is provided with fixed orifice 6, and pull bar 2 one ends pass fixed orifice 6, and fixing by nut 7; Be provided with aperture 8 on described guide plate 3, be provided with elastic ring 9 in aperture 8, pull bar 2 is movably arranged in guide plate 3, and passes aperture 8; Described connecting strap 4 is connected with pull bar 2 ends.
In the present embodiment, drawhead 1 adopts the Z-shaped structure of twice bending miter angle of steel plate, by captiveing joint of nut 7 and pull bar 2, guide plate 3 also adopts the direct bending of steel plate, so both guaranteed rigidity, cancelled again welding, simplified processing technology, the connection location of guide plate 3 is changed on lower beam connection from vertical beam simultaneously, shorten the length of pull bar 2, facilitated installation.During use, speed limiter wire rope needs to pass from the through hole 5 of drawhead 1 upper end, and fixes with wire rope grip.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (3)
1. the linkage structure of a safety tongs and velocity limiter, comprise drawhead, pull bar, guide plate and connecting strap with holes, and it is characterized in that: described drawhead is the Z-shaped structure, and the drawhead upper end is provided with through hole, and the lower end is connected with pull bar; Be provided with aperture on described guide plate, pull bar is movably arranged in guide plate, and passes aperture; Described connecting strap is connected with the pull bar end.
2. the linkage structure of a kind of safety tongs according to claim 1 and velocity limiter, is characterized in that: be provided with elastic ring in the aperture of described guide plate.
