therefore, it is single that existing elevator safety gear also exists braking direction, and braking effect is undesirable, safety is undesirable and install more inconvenient problem.
Utility model content
the purpose of this utility model is, provides a kind of elevator fluid pressure type bidirectional safety tongs.The utility model can not only realize bi-directional braking, improves braking effect and safety, also has advantage easy for installation.
the technical solution of the utility model: a kind of elevator fluid pressure type bidirectional safety tongs, comprises mount pad, is symmetrically arranged with 2 fixed blocks in mount pad; Each fixed block is all connected with two-way system motion block by chevron pointing slope, and the top of two-way system motion block and bottom are connected to upper linkage piece and lower linkage piece by boss, and in upper linkage piece and lower linkage piece, the position of corresponding boss is equipped with waist-shaped hole; The two ends of upper linkage piece and lower linkage piece are all connected with two-way hydraulic cylinder, and upper end and the bottom of each two-way hydraulic cylinder are all connected with transport pipe.
in aforesaid a kind of elevator fluid pressure type bidirectional safety tongs, described two-way hydraulic cylinder comprises cylinder barrel, is provided with piston in cylinder barrel, is connected with piston rod in the middle part of piston, and the two ends of piston rod connect linkage piece and lower linkage piece respectively.
in aforesaid a kind of elevator fluid pressure type bidirectional safety tongs, described upper linkage piece is connected 2 two-way system motion blocks with lower linkage piece all simultaneously.
in aforesaid a kind of elevator fluid pressure type bidirectional safety tongs, the side of described two-way system motion block is provided with chevron pointing side.
in aforesaid a kind of elevator fluid pressure type bidirectional safety tongs, the side of described two-way hydraulic cylinder is fixedly connected with mount pad, and two-way hydraulic cylinder is connected with Hydraulic Pump by transport pipe.
compared with prior art, the utility model improves the structure of elevator safety gear, achieving two-way gradual braking, improve braking effect by arranging fixed block, chevron pointing slope and two-way system motion block; By arranging two-way hydraulic cylinder, upper linkage piece and lower linkage piece, control 2 two-way system motion blocks along chevron pointing slope synchronizing moving up or down, eliminate transmission and the installation of velocity limiter and safety tongs shift mechanism, transmission stability when not only increasing braking, safety and braking force, also facilitate installation.Therefore, the utility model can not only realize bi-directional braking, improves braking effect, transmission stability, safety and braking force, also has advantage easy for installation.

Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.A kind of elevator fluid pressure type bidirectional safety tongs, forms as shown in Figure 1, 2, comprises mount pad 1, be symmetrically arranged with 2 fixed blocks 2 in mount pad 1; Each fixed block 2 is all connected with two-way system motion block 4 by chevron pointing slope 3, the top of two-way system motion block 4 and bottom are connected to upper linkage piece 6 and lower linkage piece 7 by boss 5, and in upper linkage piece 6 and lower linkage piece 7, the position of corresponding boss 5 is equipped with waist-shaped hole 8; The two ends of upper linkage piece 6 and lower linkage piece 7 are all connected with two-way hydraulic cylinder 9, and upper end and the bottom of each two-way hydraulic cylinder 9 are all connected with transport pipe 10.
described two-way hydraulic cylinder 9 comprises cylinder barrel 91, is provided with piston 92 in cylinder barrel 91, is connected with piston rod 93 in the middle part of piston 92, and the two ends of piston rod 93 connect linkage piece 6 and lower linkage piece 7 respectively.Described upper linkage piece 6 is connected 2 two-way system motion blocks 4 with lower linkage piece 7 all simultaneously.The side of described two-way system motion block 4 is provided with chevron pointing side.The side of described two-way hydraulic cylinder 9 is fixedly connected with mount pad 1, and two-way hydraulic cylinder 9 is connected with Hydraulic Pump by transport pipe 10.
during use, by transport pipe 10, Hydraulic Pump is connected with two-way hydraulic cylinder 9, when needing braking in ascending for elevator, Hydraulic Pump is pressed into hydraulic oil by the transport pipe 10 being positioned at two-way hydraulic cylinder 9 upper end to cylinder barrel 91, hydraulic oil promotes piston 92 and moves down, piston 92 drives piston rod 93 to move down, and piston rod 93 drives upper linkage piece 6 and lower linkage piece 7 to move down, and upper linkage piece 6 and lower linkage piece 7 drive 2 two-way system motion blocks 4 to move down by waist-shaped hole 8 and boss 5 simultaneously; 2 two-way system motion blocks 4 slide at the same time on the chevron pointing slope 3 of 2 fixed blocks 2, and draw close to centre under the effect of 2 fixed blocks 2, then clamping guide-rail, realize gradual braking, and comparatively large at the propelling thrust of hydraulic pressure, can improve braking force; When braking, because guide rail relative elevator moves down, so guide rail produces a downward friction force to two-way system motion block 4, consistent with the braking direction of two-way system motion block 4, braking force can be improved further.When needing braking during elevator is descending, Hydraulic Pump is pressed into hydraulic oil by the transport pipe 10 being positioned at two-way hydraulic cylinder 9 bottom to cylinder barrel 91, hydraulic oil promotes piston 92 and moves up, piston 92 drives piston rod 93 to move up, piston rod 93 drives upper linkage piece 6 and lower linkage piece 7 to move up, and upper linkage piece 6 and lower linkage piece 7 drive 2 two-way system motion blocks 4 to move up by waist-shaped hole 8 and boss 5 simultaneously; 2 two-way system motion blocks 4 slide at the same time on the chevron pointing slope 3 of 2 fixed blocks 2, and draw close to centre under the effect of 2 fixed blocks 2, then clamping guide-rail, realize gradual braking; When braking, because guide rail relative elevator moves up, so guide rail produces a friction force upwards to two-way system motion block 4, also consistent with the braking direction of two-way system motion block 4, still can improve braking force further.In sum, the utility model achieves bi-directional braking, improves braking force and braking effect.
