Engagement, the left side and right side of shell be provided with opening, and there are two connecting plate is set, two connecting plates are separately mounted in hoistway
Left and right side, the medial surface of connecting plate is connected with cutting ferrule, and the left side of left side riser and the right side of right side riser connect
It is connected to kelly, kelly passes through opening, kelly to coordinate with cutting ferrule, and the lower periphery of screw rod is connected with ratchet, on the left of the sliding rail of right side
Bottom in shell is connected with montant, and the top of montant is connected with guide sleeve, and the right side top of montant is connected with L-shaped bar, L-shaped bar
Top fixed pulley is installed, the left side of guide sleeve is connected with spring, and the left end of spring is connected with pawl, and pawl is matched with ratchet
It closes, the right side on well lid is provided with aperture, and the right side of pawl is connected with drawstring, and the end of drawstring initially passes through guide sleeve, further around excessively fixed
Pulley then passes through aperture, and is connected with draw ring.
Preferably, further include having lid, placing groove is provided at the top of the well lid on the right side of aperture, at the top of the well lid on the right side of placing groove
It is hingedly connected with lid by hinge member.
Operation principle：When initial, kelly is stuck in cutting ferrule, and so well lid can be fixed on hoistway, prevents from stealing people
Well lid sled is walked, so as to antitheft.And pawl blocks ratchet, can so prevent screw rod from rotating, it is antitheft so as to improve
Property.When administrative staff need open manhole cover, draw ring is pulled up, pawl can be made to move right by drawstring and unclamp ratchet,
Spring compresses therewith.Then screw rod is blocked with spanner, then screw rod is made to rotate counterclockwise, it is inverse that screw rod rotates counterclockwise band moving gear
Hour hands rotate, and gear, which rotates counterclockwise, makes the rack in left side move right, and so that the rack on right side is moved to the left, can so make two
A riser is close to each other, so as to remove kelly out of cutting ferrule, can then open well lid.When administrative staff are by well
When lid is fixed, first well lid is put back in hoistway, pulls draw ring then up, then screw rod is blocked with spanner again and makes screw rod up time
Needle rotates, and two risers can so resetted, so as to make kelly be caught in cutting ferrule, and then well lid is fixed on hoistway
On.Draw ring then is unclamped again, spring rebounds therewith makes ratchet pawl reset block ratchet.Therefore the utility model can improve antitheft
Effect can reduce personal injury, can reduce economic loss.
Because further including having lid, it is provided with placing groove at the top of the well lid on the right side of aperture, it is logical at the top of the well lid on the right side of placing groove
It crosses hinge member and is hingedly connected with lid.Draw ring is put into placing groove, then lid is covered, can so be effectively prevent passing
Pedestrian and vehicle damage draw ring, can also hide draw ring, so as to further improve the anti-theft of well lid.
（3）Advantageous effect
The utility model is blocked kelly by cutting ferrule, well lid can be fixed on hoistway, and block spine by pawl
Wheel can prevent screw rod from rotating, and can improve anti-theft effect to reach, can reduce personal injury, can reduce economic damage
The effect of mistake.
