Description
Technical field
The utility model belongs to lifting machine manufacturing technology, relates to a kind of for Superthin scissor lift safety insurance mechanism.
Background technology
Shearing type lifter safety device prior art installs a cylinder directly over secure claw, in order to control secure claw and to insure engaging and disconnection of tooth bar, this safety device is safe, reliable and easy to use, its weak point is: cylinder is arranged on directly over secure claw and occupies height space, add the height of flat surface when shearing type lifter drops to extreme lower position, if shearing type lifter not being arranged in melt pit, then be not suitable for and use compared with the vehicle maintenance of low chassis, limit shearing type lifter maintenance Applicable scope.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, propose a kind of for Superthin scissor lift safety insurance mechanism, effectively can control secure claw and insurance the engaging and disconnection of tooth bar, meanwhile, the height of flat surface when shearing type lifter drops to extreme lower position can be reduced.
For realizing the object of the utility model, be achieved by the following technical solutions: the utility model by insuring tooth bar, secure claw, oil cylinder adapter plate, cylinder, air cylinder support, jam nut, screw, flat gasket, spring chair, jackscrew, axle form, it is characterized in that: have continuous print straight-tooth teeth groove above insurance tooth bar and there is fixed orifice one end; Secure claw is L shape, and the one back side is welded with axle, and axle two ends are isometric stretches out secure claw face; Oil cylinder adapter plate profile is oval, and two ends have big hole, and centre has large square hole, and large square hole upper center has unthreaded hole, and there is tapped bore unthreaded hole both sides, have kidney slot above unthreaded hole, and there is jackscrew mounting hole at oil cylinder adapter plate upper surface two ends, and centre has groove; Described oil cylinder adapter plate is arranged on oil cylinder cover by two ends big hole, and is fixed it with jackscrew; Described insurance tooth bar is cut with scissors by jointed shaft altogether through the hole on oil cylinder adapter plate square hole broad in the middle and connecting rod and rod aperture; The axle that secure claw welds is arranged in oil cylinder adapter plate kidney slot; Air cylinder support is fixed on the tapped bore of oil cylinder adapter plate both sides by screw, flat gasket, spring chair, jam nut, and the piston rod of cylinder withstands on another back side of secure claw through unthreaded hole in the middle part of the large square hole of oil cylinder adapter plate; Air cylinder support can carry out backstop to the axle that secure claw welds, and secure claw can rotate centered by axle.
Compared with prior art, the beneficial effects of the utility model are: owing to being arranged in the middle of two oil cylinders by cylinder, secure claw, insurance tooth bar, safety insurance mechanism is made to be hidden in the middle of oil cylinder and not take height space, reduce the height of flat surface when Superthin scissor lift drops to extreme lower position, Superthin scissor lift is directly installed on ground and uses without the need to being arranged in melt pit, the vehicle maintenance that just can meet chassis very low uses, and commonality is very strong.

Detailed description of the invention
With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model discloses a kind of for Superthin scissor lift safety insurance mechanism, comprise: insurance tooth bar 1, secure claw 2, oil cylinder adapter plate 3, cylinder 5, air cylinder support 6, jam nut 7, screw 8, flat gasket 9, spring chair 10, jackscrew 11, axle 13, its key is: insurance tooth bar 1 has continuous print straight-tooth teeth groove above and there is fixed orifice one end; Secure claw is L shape, and the one back side is welded with axle 13, and axle 13 two ends are isometric stretches out secure claw 2; Oil cylinder adapter plate 3 profile is oval, and two ends have big hole, and centre has large square hole, large square hole upper center has unthreaded hole, and there is tapped bore unthreaded hole both sides, have kidney slot above unthreaded hole, there is jackscrew 11 mounting hole at oil cylinder adapter plate 3 upper surface two ends, and centre has groove; Described oil cylinder adapter plate 3 is arranged on oil cylinder cover 4 by two ends big hole, and is fixed it with jackscrew 11; Described insurance tooth bar 1 is cut with scissors by jointed shaft altogether through the hole on oil cylinder adapter plate 3 square hole broad in the middle and connecting rod 12 and piston rod 14 hole; On secure claw 2, the axle 13 of welding is arranged in oil cylinder adapter plate 3 kidney slot; Air cylinder support 6 is fixed on the tapped bore of oil cylinder adapter plate 3 both sides by screw 8, flat gasket 9, spring chair 10, jam nut 7, and the piston rod of cylinder 5 withstands on another back side of secure claw 2 through unthreaded hole in the middle part of the large square hole of oil cylinder adapter plate 3; Air cylinder support 6 can carry out backstop to the axle 13 of 2 welding on secure claw, and secure claw 2 can rotate centered by axle 13.
At Superthin scissor lift ascent stage, cylinder 5 not air feed, secure claw 2 slides on insurance tooth bar 1, if lifting machine declines, then secure claw 2 engages with insurance tooth bar 1 and plays and only fall safety effect, only have and to cylinder 5 air feed, cylinder 5 piston rod is stretched out and to shore on secure claw 2 one back side thus promote secure claw 2 to rotate up with axle 13, arming pawl 2 engages with insurance tooth bar 1, lifting machine could decline, thus, the lifting machine installing this Superthin scissor lift safety insurance mechanism is at every moment all in and prevents among the unexpected insurance declined.
Meanwhile, owing to cylinder 5, secure claw 2, insurance tooth bar 1 being arranged in the middle of two oil cylinders, make safety insurance mechanism be hidden in the middle of oil cylinder and not take height space, reduce the height of flat surface when Superthin scissor lift drops to extreme lower position
Superthin scissor lift of the present utility model is adopted effectively to prevent lifting machine from surprisingly declining, after particularly declining, there is lower flat surface height, be directly installed on ground and used without the need to being arranged in melt pit, the vehicle maintenance that just fully can meet chassis very low uses, as sport car, commonality is very strong.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited to above-mentioned citing; those skilled in the art are in essential scope of the present utility model, and the change made, remodeling, interpolation or replacement, all should belong to protection domain of the present utility model.
