Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

With reference to fig. 1 to 3, schematically showing the hoistway protection structure of the present invention, including the shaft 1, the protection component 2 and the plurality of hooks 3 located on the inner side wall of the shaft 1 that are vertically disposed, the protection component 2 includes the support ring 21 and the protection net 22 located on the inner side of the support ring 21, the protection net 22 is preferably made of nylon, and the support ring 21 is made of metal. The opening of the hook 3 is arranged towards the lower end of the shaft 1, and the free end 31 of the hook 3 bends towards the radial outer side of the shaft 1 and extends towards the lower end of the shaft 1. The protective assembly 2 is positioned inside the shaft 1, the hook 3 is hung on the support ring 21, and the side wall of the support ring 21 abuts against the free end 31 of the hook 3. The protective net 22 can prevent people from falling into the well, and the hook 3 with the opening facing downwards can prevent people from colliding with the free end 31 of the hook 3 to cause injury. Further, even if the person or article that drop impact couple 3, couple 3 can be more crooked when receiving the impact and deformation, and the free end 31 of couple 3 further buckles towards the radial outside of pit shaft 1 promptly to avoid support ring 21 accident to break away from couple 3 and cause the accident of falling into the well.

The cross-sectional area of the fixed end 32 of the hook 3 is smaller than that of the free end 31 of the hook 3, generally, a plurality of hooks 3 should be able to make the protection net 22 bear 150 kg of load, however, in case of small-amplitude overload (for example, the protection net 22 bears 170 kg of load), the hook 3 inevitably deforms, and since the cross-sectional area of the fixed end 32 of the hook 3 is smaller than that of the free end 31, the fixed end 32 of the hook 3 is bent first, so that the free end 31 of the hook 3 is further bent towards the radial outer side of the shaft 1, and at least the support ring 21 can be prevented from unhooking.

The structure further comprises a well lid 4 covering the opening of the shaft 1, the outer diameter of the well lid 4 being larger than the inner diameter of the shaft 1, which makes it impossible for the well lid 4 to fall into the shaft 1. Installing frame 5 is still installed to the up end of pit shaft 1, has on installing frame 5 and holds chamber 51, sets up the well head 52 that communicates in the inside of pit shaft 1 on the diapire that holds chamber 51, and the internal diameter of well head 52 is less than the internal diameter of pit shaft 1, and the inside wall that holds chamber 51 can carry on spacingly to well lid 4, and well head 52 then can further prevent well lid 4 from well head 52 falling into pit shaft 1.

In order to reduce the impact energy (certain kinetic energy when people or articles fall down) received by the protection net 22, the distance between the protection net 22 and the upper end face of the shaft 1 is 300-350 mm.

To sum up, the utility model discloses a well protective structure is equipped with a plurality of couples 3 on the inside wall of pit shaft 1, and the opening of couple 3 is facing to pit shaft 1's lower extreme, and the free end 31 of couple 3 is buckled and is extended to 1 lower extreme of pit shaft 1 towards 1 radial outsides of pit shaft, and couple 3 articulates in support ring 21 of protection network 22, even if pit shaft 1's well lid 4 is opened, protection network 22 also can prevent personnel from falling into the well, and this couple 3 structure can avoid personnel to collide with the free end 31 of couple 3, avoids causing personnel's injury.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
