Abstract
The utility model discloses an anti-falling rotary type inspection well protective cover. The anti-falling rotary type inspection well protective cover comprises an outer ring and an inner ring, wherein the outer ring comprises an annular outer ring body; at least three angular lugs are arranged on the outer ring body towards the outer circumferential side in a bulged manner; at least three I-shaped socket pins are arranged at the inner circumferential side of the outer ring body along the circumferential direction; the inner ring comprises a circular net-shaped inner ring body, and inlet tongues corresponding to the socket pins are arranged at the outer circumferential side of the inner ring body. The anti-falling rotary type inspection well protective cover is arranged below an inspection well cover, and is capable of preventing people from falling even though the inspection well cover is removed, so that the using safety of an inspection well is improved. Moreover, the inner ring can be rotated to be pulled out or rotated in place for being fixed, and therefore, the anti-falling rotary type inspection well protective cover is convenient to maintain, simple in structure and convenient to use.
Description
Technical field
The utility model relates to the rotary inspection shaft over cap of a kind of fall arrest.
Background technology
In inspection shaft is general there be dead size

Fig. 2 is the inner ring structure schematic diagram;
Fig. 3 is the rotary inspection shaft over cap of fall arrest mounting structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
As shown in Figure 1 to Figure 3; the rotary inspection shaft over cap of fall arrest of the present utility model comprises outer ring 1 and inner ring 2; described outer ring 1 comprises the outer ring body 10 of annular; described outer ring body is given prominence to outer circumferential sides and is provided with at least three angle ears 11; described outer ring body inner circumferential side is along being circumferentially with at least three " ［ " type socket pins 12; described inner ring 2 comprises circular netted inner ring body 20, and the corresponding described socket pin 12 of described inner ring body outer circumferential sides is provided with import tongue 21.Described outer ring body is
The reinforced steel bar ring of 14mm reinforcing bar coiling, described angle ear are the rectangle iron plate that is weldingly fixed on reinforced steel bar ring.Described inner ring body by
The 10mm steel bar welding is connected into netted, and described import tongue is the rectangle iron plate that is weldingly fixed on the inner ring body.Socket pin on described outer ring is provided with three, and described angle ear is provided with four.Socket pin and angle ear on described outer ring stagger mutually.
The mounting method of this over cap is: at first outer ring 1 is installed below the inspection well cover 30 of inspection shaft 3, then puts into inner ring 2, inner ring is concordant with the outer ring, and the import tongue of inner ring and the socket pin of outer ring stagger, and last temperature of inner ring during rotation makes the import tongue insert the socket pin and gets final product.30～70mm position, inspection well cover below is located in described outer ring.Described outer ring is embedded in advance in the inspection shaft wall or after the inspection shaft wall of having completed is got into the cave and is fixed, and in the outer ring, circular diameter lacks 20mm than the inspection well cover diameter.
