Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example (b): referring to fig. 1, 2 and 3, an internal inflow type fine grid protection structure comprises an inflow channel and an internal inflow type fine grid 1, wherein a cover plate 2 is arranged above the inflow channel, a mounting hole is reserved on the cover plate 2, and the internal inflow type fine grid 1 is mounted in the mounting hole; the periphery of the inner inflow type fine grid 1 and the edge of the mounting hole are provided with intervals. And fixed guardrails 3 are respectively arranged on the outer sides of the mounting holes corresponding to the back and two side surfaces of the inner inflow type fine grid 1, and movable guardrails are arranged on the front corresponding to the inner inflow type fine grid 1.
The movable guardrail comprises a guardrail body 4 and two vertical columns 5, wherein one opposite sides of the two vertical columns 5 are provided with sliding grooves which vertically penetrate through the two ends of the two vertical columns 5, and the two sides of the guardrail body 4 are positioned in the sliding grooves of the two vertical columns 5 and are connected with the two vertical columns 5 in a sliding fit manner; and, the balustrade body 4 can be slid out from both ends of the column 5. The lower extreme that 5 stand deviated from interior inflow thin grid 1 one side is connected with apron 2 rotation through hinge 6, is close to the vertical bolt 7 that is equipped with of lower extreme that advances one side of the thin grid 1 of inflow in 5 at the stand, on apron 2, corresponds the position of bolt 7 and is equipped with the jack.
During implementation, a limiting groove is formed in the groove bottom of the sliding groove, the upper end of the limiting groove penetrates through the upright post 5, and the lower end of the limiting groove extends to the lower end close to the upright post 5. At the both sides of railing body 4, correspond the spacing groove and be equipped with stopper 8, stopper 8 stretches into the spacing inslot to be connected with spacing groove sliding fit. Through setting up spacing groove and stopper 8, can prevent 4 roll-off stands 5 of railing body.
And the two upright posts 5 are respectively provided with a locking bolt 9, and the locking bolts 9 penetrate through the two sides of the upright posts 5, which are provided with the bolts 7 and the hinges 6, and are connected with the upright posts 5 in a threaded fit manner. Preferably, the locking bolt 9 is close to the upper end of the upright post 5; moreover, the locking bolt 9 is positioned at the outer side of the limiting groove; in this way, interference with the sliding of the balustrade body 4 is avoided. On the apron 2 that deviates from interior inflow formula thin grid 1 one side at stand 5, pre-buried lock nut has, when stand 5 turned over towards deviating from interior inflow formula thin grid 1 one side and was laminated with apron 2, lock bolt 9 can just right with lock nut to can link to each other with lock nut screw-thread fit. After the movable guardrail is turned over and laid flat, the movable guardrail is connected with the locking nut in a matching mode through the locking bolt 9, the stability of the guardrail body 4 used as a pedal can be guaranteed, and the movable guardrail can be prevented from being turned over due to the change of the center of gravity after being stepped on the pedal.
In this scheme, interior thin grid 1 positive guardrail of inflow formula is movable guardrail, when the guardrail is in vertical state, can prevent effectively that the risk between the thin grid of inflow formula 1 in follow and mounting hole edge such as personnel, object from dropping to can effectively improve the security performance. When the inward inflow type fine grid 1 needs to be maintained and overhauled, the bolt 7 is firstly pulled out, and then the whole movable guardrail is turned towards the direction deviating from the inward inflow type fine grid 1 until the movable guardrail is attached to the cover plate 2; promote railing body 4 again, make railing body 4 inwards advance the thin grid 1 of STREAMING and remove, until being close to the thin grid 1 of STREAMING in, make railing body 4 form the footboard, like this, the staff can be directly just on railing body 4 to it is more convenient to make maintenance, has effectively avoided the risk that the guardrail caused more, thereby further improves the security performance, and can improve the convenience of maintaining, maintaining.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that those modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all should be covered in the scope of the claims of the present invention.
