Description
Technical field
The invention belongs to petroleum drilling technology fields, and in particular to a kind of Novel hydraulic elevator of band folding signal designation.
Background technique
In Process of Oil Well Drilling, elevator lifting drilling rod or casing are generallyd use, elevator is remotely controlled by driller house and is risen
It falls, therefore staff cannot judge the working condition of hydraulic elevator immediately, once operator's operation error, it will lead to accident
Generation.
Also there is hydraulic elevator at present to realize that door signal indicates, is closely switched in the adjunction of lock bolt position, then pass through electric wire
It is connected in driller house, although doing so the function of realizing signal designation, has the following disadvantages: 1, being needed close to switch
Electricity consumption is wanted, real explosion-proof effect is not achieved, increases the hidden danger of platform；2, operating condition is complicated when drilling well, and excessively close to switch
Sensitive, once signal is judged by accident, operator just has the possibility of maloperation；3, elevator is lifting by crane always rise and landing, therein
Electric wire is also required to rise and fall, and electric wire is probably damaged or worn, so there are security risks；4, the adjunction of lock bolt position is closely opened
It closes, is only able to detect the signal of lock bolt closing, other signals cannot detect.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of Novel hydraulic elevators of band folding signal designation, compared to not having
Indicate that the hydraulic elevator of function can be reduced the faulty operation of staff, compared to the hydraulic crane close to switch as signal designation

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below with reference to embodiment and attached drawing to the present invention
It is described in further detail, it is as described below to be not intended to limit claimed range, but it is merely representative of selected implementation of the invention
Example.
In the description of the present invention, it should be noted that term " first ", " second ", etc. only for difference description, not
For referring to its relative importance.
Please refer to Fig. 1, Fig. 2, a kind of Novel hydraulic elevator of band folding signal designation, including left-hand door body 27, right door body 26
And fluid cylinder I 1 and fluid cylinder II 2 in fixed plate 3, it is locked between left-hand door body 27 and right door body 26 using lock bolt 9, fluid cylinder I 1 controls
The folding of left and right door body, fluid cylinder II 2 control the locking or opening of lock bolt.The end of I 1 piston rod I of fluid cylinder uses fixing bolt 15
Equipped with plug 4, plug 4 is vertically arranged with I 1 piston rod I of fluid cylinder, is fixed with top in the fixed plate 3 before being set to I 1 end cap of fluid cylinder
The mandril of bar reversal valve I 16, mandril reversal valve I 16 is arranged towards plug 4, mandril reversal valve I 16 and the oil circuit with oil path block I 17
Connection, the cylinder body tail portion of fluid cylinder II 2 is connected with fixed plate 3.
The end of I 1 piston rod I of fluid cylinder sequentially passes through right connecting rod 5, the first pull rod 6 is connected with right door body 26, the cylinder of fluid cylinder I 1
Body tail portion passes sequentially through left connecting rod 7 and the second pull rod 8 is connected with left-hand door body 27, wherein the shell of left and right connecting rods and hydraulic elevator
Between it is fixed by the activity of fixing axle 30, left and right connecting rods are in bending, and left-hand door body 27 is bent in the same direction with left connecting rod 7
Setting, right door body 26 are in bending with right connecting rod 5, and right door body 26 is bent setting with right connecting rod 5 in the same direction.Door opening action
Mechanism principle: I 1 piston rod I of fluid cylinder retracts, and right connecting rod 5 rotates counterclockwise, and the first pull rod 6 is driven to rotate clockwise, and drives door body
It opens, the hydraulic letter that opens the door is realized in the mandril of the contact pressing mandril reversal valve I 16 of plug 4, I 16 oil circuit of mandril reversal valve commutation
Number output.
The end of II 2 piston rod II of fluid cylinder sequentially passes through pull head 10, third pull rod 11, four-pull-rod 12 and is connected with lock bolt 9,
Rotatable connection ring 13, the tail portion of third pull rod 11, four-pull-rod 12 are installed on the door-hinge 14 being set in left-hand door body 27
End be both secured in connection ring 13, so realize third pull rod 11 rotation drive connection ring 13 rotation, 13 turns of connection ring
Dynamic that four-pull-rod 12 is driven to rotate, pull rod II 12 drives lock bolt 9 to rotate in turn, realizes the opening and closing movement of lock bolt 9.
Fig. 1-4 is please referred to, retaining mechanism is provided on lock bolt 9, retaining mechanism includes lock bolt closing organ and lock bolt lock
Tight mechanism.Lock bolt closing organ includes the oil path block II 18 for being fixed on right door body 26, the idler wheel with II 18 oil communication of oil path block
The idler wheel 20 of reversal valve 19, idler wheel reversal valve 19 is tightly attached to lock bolt 9.Lock bolt closing organ principle: when fluid cylinder II 2 drives lock bolt 9
When closing, II 2 piston rod II of fluid cylinder stretches out, and pull head 10 is driven to rotate counterclockwise, and third pull rod 11, connection ring 13 are revolved counterclockwise
Turn, so that four-pull-rod 12 be driven to rotate clockwise, drives lock bolt 9 to rotate counterclockwise around a axis (such as Fig. 3), lock bolt 9 is driven to close
It closes, the idler wheel 20 of squeezing roller reversal valve 19 while lock bolt 9 rotates, hydraulic pressure signal is realized in the commutation of 19 oil circuit of idler wheel reversal valve
Output, if lock bolt 9 is not turned off, lock bolt 9 and idler wheel 20 are not contacted, and hydraulic oil does not export, thus without hydraulic pressure signal it is defeated
Out.

Bar reversal valve II 23 is fixed in a boss 22 of lock bolt 9, one end of the 21 face latch pin 24 of mandril of mandril reversal valve II 23,
The sliding of latch pin 24 is set to right door body 26, and the other end of latch pin 24 is connected with one end of lever 21, and the other end of lever 21 is set
In the bottom for the mandril axis 29 being slideably positioned in right door body 26, the top of mandril axis 29 is affixed on the liner 28 of hydraulic elevator, lock
The outside of rod bolt 24 is also arranged with pressure spring 25, and pressure spring 25 is set between right door body 26 and lever 21.Latch pin 24 and mandril axis
29 are separately positioned on the both ends of lever 21 and are located at the ipsilateral of lever 21.Lock bolt pin locking mechanism principle: mandril axis 29 falls then
Latch pin 24 jacks up, and the jack-up of latch pin 24 can prevent lock bolt 9 from rotating around a axis, plays the function of lock bolt locking；Now by 25 sets of pressure spring
Outside latch pin 24, pressure spring 25 is contacted with right door body 26, and due to the effect of pressure spring 25, liner 28 cannot be by lock bolt with self gravity
Pin 24 jacks up, and is only equipped with casing in liner 28 or when drilling rod increases gravity, will in the state that lock bolt 9 has been switched off
Latch pin 24 jacks up, and presses the mandril of mandril reversal valve 23, the output of hydraulic pressure signal is just able to achieve, in this way, only in liner
Having in 28 can just realize that lock bolt pin locked hydraulic pressure signal exports when casing or drilling rod, it is ensured that safety.
