All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention comprises a chassis 1, wherein the bottom of the chassis 1 is provided with universal wheels 2, and the universal wheels 2 have the braking function. A support 3 is fixed on the front end surface of a chassis 1, a traction rod 4 is fixed on the rear end surface of the chassis 1, the support 3 is used for fixing the device, the traction rod 4 is used for pushing the chassis 1, the front end refers to the side close to a well lid, and the side far away from the well lid is the rear end. In order to move conveniently, the draw bar 4 is provided with a handrail 5, and the whole device can be pushed by holding the handrail 5 by hand. Preferably, a towing hook 17 is integrally provided at the rear end of the towing bar 4, and when the whole device is moved for a long distance, the towing hook 17 is used for being hung on a moving vehicle, so that the moving vehicle drives the whole device to move.

An electric jack 6 is fixed in the middle of the support 3, an electric winch 7 is fixed at the top of the support 3, a battery 25 is fixed at the top of the support 3, and the battery 25 is a power supply of the electric jack 6 and the electric winch 7.

The electric hoist 7 is wound with a rope 8, and the rope 8 is preferably a wire rope. The hook is fixed at the front end of the rope 8 and used for stretching into an opening hole of the well lid to hook the well lid. The opening holes of the current manhole cover are roughly two types, one is the opening hole without a cross rod in the middle as shown in figure 3, and the other is the opening hole with the cross rod in the middle as shown in figure 4, so that the preferred hooks are two types, namely a hook 9 suitable for the opening hole with the cross rod in the middle and an X-shaped hook 10 suitable for the opening hole without the cross rod in the middle. A node ring 11 is fixed at the front end of the rope 8, the node ring 11 is a small circular ring, and the hook 9 and the X-shaped hook 10 are respectively connected to the node ring 11 through the rope 8. And when the opening hole is touched, a proper hook is selected for use.

The preferred X-shaped hook 10 is configured as follows: the X-shaped hook 10 comprises two arc-shaped bent sleeves 18 which are fixed together, and the two arc-shaped bent sleeves 18 form an X shape. The arc-shaped bent sleeve 18 is provided with an arc-shaped groove 19, and a spring 20 and an inner bent rod 21 are arranged in the arc-shaped groove 19. One end of the spring 20 is fixed on the inner wall of the arc-shaped groove 19, the other end is fixedly connected with the inner bent rod 21, and the inner bent rod 21 can slide in the arc-shaped groove 19. The opening of the arc-shaped slot 19 is arranged on the side surface of the arc-shaped bent sleeve 18. The inner bent rod 21 is vertically connected with a shift lever 22, the shift lever 22 extends out of the arc-shaped bent sleeve 18 from the opening of the arc-shaped groove 19, and the shift lever 22 can be shifted to enable the inner bent rod 21 to slide along the arc-shaped groove 19.

The notch ring 24 is a ring with a notch, and the size of the notch is larger than that of the shift lever 22, so that the shift lever 22 can pass through the notch. The notch ring 24 is sandwiched between the two rods 23 on both sides. The notch ring 24 can rotate around the arc-shaped bent sleeve 18, thereby changing the position of the notch and being used for blocking the shifting rod 22 to lock the inner bent rod 21. When meetting the cross like this and opening the hole, put into the cross with X type hook 10 earlier and open downtheholely, then stir driving lever 22 and follow arc 19 and slide down, thereby interior knee 21 roll-off in curved cover 18 of arc follow, the 19 openings of arc are aimed at to the breach of breach ring 24, let driving lever 22 pass through from the breach, dial driving lever 22 to breach ring 24 below, then rotate breach ring 24, make the breach position keep away from driving lever 22, at this moment loosen driving lever 22, driving lever 22 is blocked by breach ring 24, then interior knee 21 is fixed a position, at this moment the interior knee 21 of both sides hooks the well lid inner wall.

In order to further guarantee the stability of whole device, set up the anti-overturning device as preferred scheme, be equipped with rectangular shape extension board 12 respectively in the front end left and right sides of chassis 1, the distance between both sides extension board 12 is greater than the diameter of well lid, and extension board 12 bottom is equipped with universal wheel 2, and same universal wheel 2 has the brake function. The space between the extension boards 12 on both sides can let the device further impel to the well lid, better control opening and shutting of well lid. The bottom of the extension plate 12 is fixedly connected with an anti-overturning sleeve 13, the anti-overturning sleeve 13 is a downward-inclined sleeve, the interior of the anti-overturning sleeve is hollow, and preferably, the included angle between the anti-overturning sleeve 13 and the horizontal plane is 10-45 degrees. An inner cylinder 14 is arranged in the anti-overturning sleeve 13, and the inner cylinder 14 can rotate and slide in the anti-overturning sleeve 13. An inverted U-shaped opening 15 is formed in the anti-overturning sleeve 13, as shown in fig. 5, the inner cylinder 14 is vertically connected with a push rod 16, the push rod 16 extends out of the inverted U-shaped opening 15, and when the push rod 16 is pushed to the bottommost end of the inverted U-shaped opening 15, the bottommost end of the inner cylinder 14 is flush with the bottom end of the universal wheel 2. When the overturn preventing device is used, the push rod 16 is pushed downwards to make the inner cylinder 14 slide outwards, when the push rod 16 is pushed to the lowest end of the inverted U-shaped opening 15, the lower end of the inner cylinder 14 contacts the ground, then the push rod 16 is rotated to make the push rod 16 enter the lowest point of the inverted U-shaped opening 15, and at this time, the push rod 16 cannot slide downwards or upwards, so that the inner cylinder 14 is fixed, the inner cylinders 14 on the two sides play a further supporting role, and the whole device is prevented from overturning towards one side.

The working process of the invention is as follows:

the device is moved to a well lid to be opened by holding the handrail 5 to push or hanging the traction hook 17 on the moving vehicle, the well lid is positioned between the extension plates 12 on the two sides, the electric jack 6 faces the well lid, the push rod 16 is pushed to enable the inner cylinder 14 to stretch out to contact the ground, and then the push rod 16 is rotated to fix the inner cylinder 14. The form according to the hole is opened to the well lid selects X type hook 10 or crotch 9, open the hole with X type hook 10 or crotch 9 through the well lid and hook the well lid, start electric hoist 7, retrieve rope 8 and upwards pull up the well lid, when rope 8 and well lid are located the coplanar, at this moment well lid turned angle has been greater than 90 degrees, be the obtuse angle with the plane contained angle before the well lid is opened promptly, at this moment electric hoist 7 antiport, rope 8 extension, under the effect of well lid dead weight, the well lid continues to be opened, when the angle of opening that needs, electric hoist 7 stop work can.

When the well lid is closed, restart electric hoist 7, retrieve rope 8, when rope 8 and well lid are located the coplanar, start electric jack 6, electric jack 6 contacts and promotes the well lid, let the well lid toward the opposite direction when opening and rotate, electric hoist 7 begins the reversal during electric jack 6 contact well lid, extension rope 8, make well lid opening angle slowly become the acute angle by the obtuse angle, at this moment control electric jack 6 and well lid break away from the contact, the well lid continues to be closed under the dead weight, electric hoist 7 stop work after the well lid is closed, it can to take off the couple at last.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
