In figure: 1. well lid; 2. rail wheel; 3. track; 4. push rod; 5. bearing pin; 6. flange; 7. foot-driven lever; 8. backstay; 9. location pole socket; 10. basement well lid pedestal; 11. rail wheel mouths.
The specific embodiment
In order to understand better the present invention, below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is described further.
The slip well lid of simple operation provided by the invention, as shown in Figure 1, it comprises well lid 1, rail wheel 2, track 3, lifting body and locking mechanism to its structure, and wherein, lifting body comprises push rod 4, bearing pin 5, flange 6 and foot-driven lever 7, and lifting body is quadruplet; Locking mechanism comprises shown in backstay 8, location pole socket 9(Fig. 2), locking mechanism is two covers.The both sides, front and back of well head are respectively equipped with track (track is fixed on basement well lid pedestal 10); Each track is provided with two rail wheel mouths.Well lid is positioned at the top of well head, and four bights of well lid are respectively equipped with rail wheel, and rail wheel is positioned at (2 rail wheels of the same side are positioned on same track) on track.Each rail wheel mouth below is provided with lifting body, the flange of lifting body be positioned at rail wheel mouth under; Push rod is by bearing pin and basement well lid pedestal hinged (bearing pin is fixed on the side of basement well lid pedestal, and push rod is arranged on bearing pin), and from bearing pin, the one end close to is provided with flange to push rod, and the push rod other end is provided with foot-driven lever.Between two lifting bodies of well head the same side, be provided with locking mechanism; Location pole socket is fixed on basement well lid pedestal, and backstay is T-shaped, and the lower end of backstay is hinged on the pole socket of location.When well lid is closed, four rail wheels fall into respectively corresponding rail wheel mouth.
Described well lid 1 adopts steel plate to make, and it is shaped as square, and area is greater than well head, and four angles are rounding, in case hurt sb.'s feelings.
Rail wheel 2 adopts bearing and steel plate to make, and its structure surrounds a П type by three block plates, is installed with axle bearing is fixed in the bottom of П type.
Track 3 adopts angle steel to make, and in the time that well lid 1 is closed, the relative position of rail wheel 2 correspondences has rail wheel mouth 11, so that well lid sinks, is seated on basement well lid pedestal 10.
Push rod 4 adopts steel plate to make, and is shaped as √ type, is provided with hole, so that push rod is arranged on bearing pin 5 in the turning point of √ type.
Bearing pin 5 adopts reinforcement fabrication, and one end is embedded on basement well lid pedestal 10, and the other end has screw thread and nut is installed, so that fixed mandril 4.
Foot-driven lever 7 is located at the end of push rod √ type structure, by a straight-bar and a brace, is connected with push rod end, forms a triangular facet, so that operating personnel trample.
Backstay 8 adopts reinforcement fabrication, is two T-shaped welding of reinforcing bar, and one of straight section is provided with groove and hole, to be hinged on the pole socket of location.
Location pole socket 9 adopts steel plate to make, and is base plate and otic placode, and base plate is processed into box-shaped and is arranged on basement well lid pedestal 10, and otic placode is processed into rectangle, and one is connected with base plate, and rounding is processed in other end, and is provided with hole, to backstay 8 is installed.
Slip well lid provided by the invention uses in the time of staff's regular maintenance and maintenance underground installation discrepancy basement.
When use, close as original state (shown in Fig. 3) take well lid 1, now, rail wheel 2 drops in the rail wheel mouth 11 of track 3, and track 3 does not have load-bearing, and well lid 1 is pressed on basement well lid pedestal 10.Need to open time, first operating personnel trample two foot-driven levers 7 of a side simultaneously with pin, and push rod 4 is rotated centered by bearing pin 5, two flanges 6, two rail wheels 2 of jack-up well lid one side simultaneously, the upper surface of flange 6 is concordant with track 3, then backstay 8 is mentioned, and hooks two foot-driven levers 7.With two rail wheels 2 of identical method jack-up well lid 1 opposite side, now, well lid 1 has left basement well lid pedestal 10 completely, and load-bearing, on track 3, promotes well lid gently, just can open access.In the time that needs are closed access (shown in Fig. 4), first unclamp the backstay 8 of both sides, flange 6 is not supported, then well lid 1 reduction is closed to access, rail wheel 2 slides and drops in the rail wheel mouth 11 of track 3.
Basement well lid pedestal 10 is reinforced concrete structure, and it pours into basement higher than periphery terrace with rainwater-proof deposition; Its side is reserved with embedded iron parts, so that attachment rail 3.
Effect: the severe and access sealed by well lid of dust atmosphere, adopt after method of the present invention, opening and closing access smoothly, is convenient to the discrepancy of staff's regular maintenance and maintenance underground installation, illustrates that method effect of the present invention is remarkable.
More than explanation is only Application Example of the present invention, certainly can not limit with this interest field of the present invention, and the equivalence of therefore doing according to the present patent application the scope of the claims changes, and still belongs to protection scope of the present invention.
