The ball engaging slot 19 of indent, the upper and lower two sides of ball engaging slot 19 are provided on the cylindrical surface of 7 18 lower end of slide bar main body
On, it is respectively arranged with ball and pushes inclined-plane 20.The lower end of lifting slide bar 7 is slidably arranged in the sliding cavity 30 of guide holder 3, and is led
Locking ball 8 on 3 side wall of seat is clamped with 19 phase of ball engaging slot for going up and down 7 lower end of slide bar, and then by under lifting slide bar 7
It holds ball engaging slot 19 and the cooperation for the ball 8 that locks to be clamped, come the vertical position for the lifting slide bar 7 that locks, realizes to well lid
Locking.The lower end of lifting slide bar 7 is provided with the slide bar limited post 14 arranged straight down, and the lower end of slide bar limited post 14 passes through
The limited post through-hole 32 of 3 sliding cavity of guide holder, 30 bottom surface；And then the position of mechanical restriction lifting 7 raising and lowering of slide bar.
The outside of 3 guide bracket main body of guide holder, 28 lower part, movable sleeve are equipped with locking pressing sleeve 9, lock pressing sleeve 9 by pressing sleeve main body 33
It constitutes, the ball pressing chamber 35 for being internally provided with upper opening of pressing sleeve main body 33, is set on the outside of 33 upper end opening of pressing sleeve main body
It is equipped with end flange 34；The lower end of pressing sleeve main body 33 is provided with jacking portion 36.It locks the jacking portion 36 of 9 lower end of pressing sleeve and fixes outer
Be provided with lifting body between the lower end of 4 inside of set, lifting body include several groups along 4 cross-sectional circumferential of fixed jacket, etc. between
Pressing sleeve away from arrangement jacks pin 13, and the upper end of each group pressing sleeve jacking pin 13 is in contact with the jacking portion 36 of locking 9 lower end of pressing sleeve；Pressure
Between the lower end surface of 4 inside of lower end and fixed jacket of set jacking pin 13, then jacking spring 12 is respectively arranged with.
The lower section of pressing sleeve 9, the lower part of 4 inside of fixed jacket are locked, electricity is provided with by 11 Liftable type of magnet fixing axle
Magnet 10.To be lifted to realize that pressing sleeve jacks the jacking that 13 pairs of pin are locked pressing sleeves 9 by the elastic force of jacking spring 12, so that
Locking pressing sleeve 9 is synchronized and is moved up with the rising of lifting slide bar 7, and then under the blocking that electromagnet 10 is not powered on, is made
The ball pressing chamber 35 of pressing sleeve 9 is locked to 8 continuous extrusion of locking ball on 3 side wall of guide holder, it is ensured that locking ball 8 blocks always
It closes in the ball engaging slot 19 of lifting 7 lower end of slide bar, with the position for the lifting slide bar 7 that locks.Also, it is powered in electromagnet 10
Adsorb locking pressing sleeve 9, unlock when, by jacking spring 12 compression, for lock pressing sleeve 9 rising reset (be latched again
When) accumulation of energy., it is understood that during well lid latch hook pushes lifting slide bar 7, locking, using lifting 7 lower end of slide bar
Slide bar limited post 14 auxiliary push locking pressing sleeve 9.
Lifting slide bar 7 is located in the locker mounting groove 21 of 3 mounting flange of guide holder, 29 top one end, is provided with for locking
The latch hook fixing clamp 6 of well lid latch hook；The outer sheath of latch hook fixing clamp 6 is equipped with latch hook deck 1, and latch hook deck 1 is by deck main body 15
It constitutes, deck main body 15 is internally provided with the locking chamber 16 that longitudinal cross-section is T-type, is provided in the chamber 16 that locks for accommodating well
The lock hook slot 17 of cover lock hook；Meanwhile the lower end of latch hook deck 1 is connected by support sleeve 2 with the top of 3 mounting flange 29 of guide holder
It connects.Latch hook fixing clamp 6 is made of the first locker 22 for being mutually in the stacked pivot knot of forked type and the second locker 23, and the first of forked type arrangement
The upper end of locker 22 and the second locker 23 is respectively arranged with the locking clamping opening 24 being arranged symmetrically, each lock clamping opening 24 and latch hook deck
The outside that 1 T-type locking 16 lower part of chamber is in contact, is respectively arranged with arc bump 25.First locker 22 and the second locker 23
Between the lower end in locker mounting groove 21, then the compression spring for separating the first locker 22 and the second locker 23 is provided with
27.Also, the first locker 22 and the second locker 23 pass through the hinge hole 26 at middle part and the locker mounting groove 21 of lifting 7 upper end of slide bar
Side wall is hinged.And then it is capable clamping to utilize the first locker 22 arranged in forked type and the second locker 23 to be hooked into pattern manhole cover lock, and
During lifting slide bar 7 rises (electromagnet 10 energization adsorbs locking pressing sleeve 9), unlocks, by the elastic force of compression spring 27,
The first locker 22 and the second locker 23 for driving latch hook fixing clamp 6 separate.
When the pattern manhole cover lock is in blocking (electromagnet 10 is not yet powered, as shown in Figure 2), positioned at the T-type of latch hook deck 1
The latch hook fixing clamp 6 of locking 16 lower part of chamber is hooked into capable clamping, locking of the realization to well lid to pattern manhole cover lock.When someone is in well lid locking
When being lifted up well lid under lock status, lifting slide bar 7 being driven to move up, due to jacking the elastic force of spring 12,9 jacking portion of pressing sleeve is locked
36 lower end pressing sleeves jacking 13 pairs of locking pressing sleeves 9 of pin carry out jacking lifts so that locking pressing sleeve 9 with go up and down slide bar 7 it is upper
It rises and synchronizes and move up, thus under the blocking that electromagnet 10 is not powered on, allow the ball pressing chamber 35 of locking pressing sleeve 9
To 8 continuous extrusion of locking ball on 3 side wall of guide holder, it is ensured that locking ball 8 is fastened on the ball of lifting 7 lower end of slide bar always
In engaging slot 19, with the position for the lifting slide bar 7 and latch hook fixing clamp 6 that lock, prevent from opening the malice of well lid.
When needing normally-open well lid, (such as: can be 3V, the smaller current of 200mA) is powered for electromagnet 10；With
Afterwards, the magnetic force of electromagnet 10 adsorbs pressing sleeve 9 is locked downwards, and then releases 35 pairs of ball pressing chamber guiding of locking pressing sleeve 9
The extruding of locking ball 8 on 3 side walls of seat.When construction worker continues upper lift well lid, with pattern manhole cover lock hook strip moveable lock hook
The ball of the process that fixing clamp 6 and lifting slide bar 7 move up together, 19 downside of lifting 7 lower end ball engaging slot of slide bar pushes
Locking ball 8 is temporarily pushed into the space between 4 inner wall of 3 outer wall of guide holder and fixed jacket and (releases to lifting by inclined-plane 20
The locking of 7 vertical position of slide bar).As the T for removing latch hook deck 1 in the locking clamping opening 24 of lifting 7 upper end latch hook fixing clamp 6 of slide bar
When the lower part of type locking chamber 16, by the elastic force of compression spring 27, the first locker 22 and the second locker of latch hook fixing clamp 6 are driven
23 separate (as shown in figure 11), thus open manhole cover.
While operating personnel's maintenance finishes, shuts well lid, well lid latch hook pushes latch hook fixing clamp 6 and lifting slide bar 7, makes
First locker 22 of latch hook fixing clamp 6 and the second locker 23 collapse the lower part for being returned to the T-type locking chamber 16 of latch hook deck 1；And
Locking pressing sleeve 9(is jacked up by the reseting elasticity of jacking spring 12 at this point, electromagnet 10 has powered off), utilize locking pressing sleeve 9
Locking ball 8 on 3 side wall of guide holder is squeezed into the ball engaging slot 19 of lifting 7 lower end of slide bar by ball pressing chamber 35 again
It is interior, to realize the locking to lifting slide bar 7 and 6 position of latch hook fixing clamp.
