Description
Technical field
The utility model belongs to the improvement of water supply and draining, heating, communication pipe trench well head well lid, particularly a kind of liftable well lid.
Background technology
At present, pipeline, the circuit of communal facilitys such as the water supply and draining in the urban construction, heating, communication are installed in the underground pipe trench, and the well lid of pipe trench well head extensively adopts casting iron well lid.The weight of casting iron well lid is big, in the time of need opening well lid, well lid could be opened with the very big strength of cleek expense, and inconvenient operation, inefficiency, and also dangerous.
Summary of the invention
The purpose of this utility model is to provide a kind of liftable well lid, opens or to load onto well lid very convenient, and rapid operation, high efficiency, safe and reliable.
The purpose of this utility model is achieved in that a kind of liftable well lid, comprise the well lid of installing on the wellhead receptacle, the screw rod that matches with screw is installed in the screw that is provided with on wellhead receptacle, the upper end of screw rod is installed in the bearing support of well lid back side avris by bearing, top at screw rod is equipped with drive, the rotating shaft that top has link is installed in the through hole that is provided with on well lid, and the drive that install the bottom of rotating shaft drives the drive that installs on the screw rod by transmission device.
When opening well lid of the present utility model, the sleeve of handle is inserted in the link of well lid through hole shaft, turning handle makes rotating shaft drive drive and drives the drive that installs on the screw rod by transmission device, rise thereby make in the screw of screw rod rotation from wellhead receptacle, the screw rod of rising drives well lid and rises on the ground.With well lid is 180 ° of the horizontal sidespins in axle center with the screw rod, makes well lid leave well head.When work finishes, the well lid revolution is put in place, counter-rotating handle, transmission device drive the screw rod counter-rotating, and screw rod drives well lid decline return.The utility model is opened and to load onto well lid very convenient, rapid operation, and high efficiency, safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is the utility model sectional structure schematic diagram.
The specific embodiment
A kind of liftable well lid, as shown in drawings, comprise the well lid of installing on the wellhead receptacle 24, in the screw that on wellhead receptacle 2, is provided with the screw rod 1 that matches with screw is installed, the upper end of screw rod 1 is installed in the bearing support of well lid 4 back side avris by bearing, and by bearing gland with bearing fixing.Termination in screw rod 1 upper end is being provided with the retaining cap, constrains in the bearing support of well lid 4 by bearing and the bearing gland upper end with screw rod 1.On the top of screw rod 1 drive 3 is installed, in the through hole that is provided with the rotating shaft 6 that top has link is installed on well lid 4, the link of rotating shaft 6 is square head or turret head, and the link of rotating shaft 6 matches with the sleeve that has handle.Capping 5 is installed on the through hole of well lid 4, can prevents that silt from entering in the through hole.When opening well lid 4, open capping 5 earlier; After closing well lid 4, capping 5 is fastened on the through hole of well lid 4.The drive 7 that install the bottom of rotating shaft 6 drives the drive 3 that installs on the screw rod 1 by transmission device rotates screw rod 1.Transmission device is gear drive, and drive 3,6 is a pitch wheel.Transmission device is chain drive, and drive 3,6 is a sprocket wheel, by chain drive.
Material manufacturings such as well lid 4 of the present utility model can be cylinder iron, plastics, glass fiber reinforced plastic, resin.Manufacturing process is simple, and cost is not high, and market prospects are more wide.
