Abstract
The utility model relates to a locking device for an inspection well, which is suitable for various underground pipelines. The utility model is characterized in that the lower part of a well cover plate is provided with a rotary lock plate, and the lock plate is provided with a lock hole; when the lock plate rotates to the position which locks the well cover plate, the lock hole is opposite to a lock hole on the well cover plate, and then a pin is inserted for fixedly locking the well cover plate. Simultaneously, a pin hole is provided with a dust cap for preventing earth covering. The utility model has the advantages of simple device and easy manufacture.
Description
The utility model relates to the locking device on the various underground pipeline well lids.
Along with being on the increase of urban Underground pipeline engineering, various manholes spreaded all over road both sides or road central authorities in recent years, and it is very serious that the manhole cover plate is lost phenomenon, and the people, animal injures and deaths phenomenon that causes thus also constantly takes place.About the locking method of manhole cover plate, the patent No. that has Patent Office of the People's Republic of China to announce in 88 years is that 88203270,9 " manhole cover locks " by name can reach anti-lost phenomenon, but this locking fabrication technique complexity, and application life is low, and a lot of weak points are arranged.
The utility model is in order to overcome the deficiency of prior art, made a kind of simple in structure, the manhole locking device of long service life.
As described in Figure 1, technical characterstic of the present utility model is achieved in that it is made up of main shaft 8, well lid plate 3 and nut 7 etc.Main shaft 8 is through in the pin-and-hole of well lid plate 3, the other end that its lower end is fixed with jam plate 5 jam plates 5 has a pin-and-hole, its size is same as pin-and-hole on manhole cover plate 3 limits and the pin-and-hole on the well seat 2, and closing of well lid plate 3 is to be through in the pin-and-hole of well lid plate 3, well seat 2, jam plate 5 by bearing pin 4 to realize.The top of main shaft 8 is the square nut, has the middle part of a countersunk head garden, axle to be through in the square hole of jam plate 5 down, and bearing pin 4 is a Cylinder, and there is a countersunk head garden upper end, and it is to be tightened in the screw of well lid plate 3 that there are a screw, dustproof bolt in its top central authorities.
Use the manhole cover of the present utility model phenomenon that can prevent loss.
The structure chart of accompanying drawing 1, manhole locking device.
Provide an implementation method below in conjunction with accompanying drawing.
In the time of by dress manhole cover plate 3, earlier main shaft 8, jam plate 5, nut 7 and packing ring 6 etc. are fitted together, if lock cover plate 3, want elder generation the pin-and-hole of cover plate 3 to be aimed at the pin-and-hole of well seat 2, make the pin-and-hole of jam plate 5 be right against above-mentioned two pin-and-holes with spanner rotary main shaft 8 then, and put into bearing pin 4, tighten dustproof bolt at last and get final product.
When opening well lid plate 3, take off with the spanner bolt 1 that will prevent dust earlier, screw in the screw on bearing pin 4 tops rotation with special tool again and mention bearing pin 4 and its taking-up, last rotary main shaft 8 are got final product.
