Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended that the restriction to protection scope of the present invention.
As illustrated in fig. 1 and 2, the elevator spider of the present invention, including main body 1, valve 2 and slips 3, valve 2 is connected with main body 1
Connecing, connect for convenience, valve 2 is connected with main body 1 by two joint pins 10, and valve 2 bottom is fixed with guide ring 7, card
Watts 3 is three-chip type slips, and slips 3 is installed slip insert 4, and main body 1 top is provided with top guide plate 5, and main body 1 bottom is provided with
Lower guide plates 6, lower guide plates 6 is connected with the conical guider 8 of lower section, and main body 1 is internally installed insurance institution 9.
Shown in Fig. 3, insurance institution 9 includes insuring cylinder 96, safety plug 97, latch segment 91, spring piston assembly and control
Handle 92, locks in safety plug 97 inserts in insurance cylinder 96 and by latch segment 91, has for locking insurance in latch segment 91
The dead bolt 98 of pin 97, joystick 92 lower end is connected with spring piston assembly, joystick lower end and the company of spring piston assembly
The place of connecing is provided with an overload pin 99, and this overload pin 99 is used for controlling safety plug 97 and moves up and down, and spring piston assembly includes that spring is lived
Stopper rod 93, spring 94 and spring piston set 95, spring 94 and spring piston set 95 are all placed on spring piston bar 93.
One spacing place, right angle 971 is formed at safety plug 97 top, and a spacing place, inclined-plane 972 is formed at safety plug 97 bottom.
With reference to shown in Fig. 4 (a), now joystick 92 is in upper position, and slips body is in buckling state, when with crow bar
When prizing rack rod 11, safety plug 97 is locked by dead bolt 98, and dead bolt 98 is stuck in the spacing place, right angle that safety plug 97 top is formed
In 971, it is impossible to prize, safety plug 97 can not move downward, i.e. slips body can not move up, and plays safety effect；
With reference to shown in Fig. 4 (b), now joystick 92 is in lower position, and slips body is in open mode, overload pin 99
Acted on by spring 94 with joystick 92, stop safety plug 97 to move up, at this moment overload pin 99 end shown in Fig. 4 (b)
In the spacing place, inclined-plane 972 that safety plug 97 bottom is formed, slips body is at open position and locks and can not move down；
With reference to shown in Fig. 4 (c), when slips body needs to decline, being lifted up joystick 92, overload pin 99 will depart from guarantor
Danger pin 97, safety plug 97 will be moved upward by slips deadweight.
Valve 2 is connected with main body 1 by two joint pins 10, and slip insert 4 is arranged in slips 3, top guide plate 5,
Lower guide plates 6 and conical guider 8 are each attached in main body 1, and valve bottom guide ring 7 is fixed on valve 2, insurance institution
9 are arranged on main body 1 inside, it is possible to effectively play safety effect.
Elevator spider uses the design of three-chip type card tile structure, and clamping tubing string realizes 360 degree and entirely surrounds, tubing string uniform force,
Setting of casing is rapid, easy to operate, safe and reliable, and slips back cone uses multi-step structure, bears load bigger.
This insurance institution 9, after slips 3 promotes, insurance institution 9 starts working, when changing slips 3 or slip insert 4 not
Slips 3 can be occurred due to the situation of gravity fall, it is to avoid have an accident, be greatly improved the safety of operation.Due to page three cards
Watts 3 act on simultaneously, well partially in the case of also be able to normally use.
