Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
With reference to figures 1 to 3 of the drawings,
the utility model provides a portable well lid lifting device for further explanation.
A portable well lid lifting device comprises two hydraulic jacks 1 and two jack suites 2; the top of a piston rod of each hydraulic jack 1 is respectively inserted with a jack sleeve member 2, the inner surfaces of circular rings at the upper ends of the two jack sleeve members 2 are sleeved with a stress rod 4, the two jack sleeve members 2 are positioned at two ends of the stress rod 4, the middle position of the outer surface of the stress rod 4 is sleeved with two push-pull rod sleeve members 3, and the bottoms of the two push-pull rod sleeve members 3 are respectively connected with a push-pull rod 5 through a U-shaped hanging ring
The bottoms of the two jack assemblies 2 are provided with slots, piston rods of the two hydraulic jacks 1 are inserted into the slots at the bottoms of the two jack assemblies 2, and the slots are matched with the piston rods of the hydraulic jacks 1.
The inner diameter of the upper end of the jack sleeve member 2 is larger than the outer diameter of the stress rod 4, and the inner diameter of the push-pull rod sleeve member 3 is larger than the outer diameter of the stress rod 4.
The bottom ends of the two push-pull rods 5 are T-shaped heads with 90 degrees.
Before lifting the well lid, a worker needs to sleeve the push-pull rod sleeve 3 at the middle position of the stress rod 4, the inner diameter of the push-pull rod sleeve 3 is larger than the outer diameter of the stress rod 4, then the push-pull rod 5 is hung in a circular ring at the bottom of the push-pull rod sleeve 3 through a U-shaped hanging ring, then the two jack sleeve 2 are sleeved at two ends of the stress rod 4, the inner diameter of the push-pull rod sleeve 3 is larger than the outer diameter of the stress rod 4, then the slots at the bottom of the two jack sleeve 2 are sleeved at the top of the piston rod of the hydraulic jack 1, and the slots are matched with the piston rod of the hydraulic jack, so that shaking can not occur between the jack sleeve and the hydraulic jack during operation, the operation is affected, and then the hydraulic jack 1 is placed on the ground at two sides of the well lid.
