Mine draw shaft safety protection structure

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clearer understanding of the present invention, but they do not limit the present invention.

[0017] Such as figure 1 , figure 2 As shown, the present invention includes a fixed support 1 arranged on the well wall above the outer side of the chute head, and an oil cylinder support 2 is provided on the chute below the fixed support 1 and the fixed support 1 and the main beam 3 The head end is hinged. The main beam 3 is bent as a whole, preferably a C-shaped main beam. The front section of the main beam 3 extends from the top of the outside of the chute to the entrance of the chute, and the front section of the main beam 3 is hinged with the cylinder support 2. There is an upper cylinder 4, and the rear section of the main beam 3 abuts against the top edge of the well head and extends obliquely upward into the well head, that is, the rear section of the main beam 3 is on the eyebrow line of the well head, and the main beam 3 The end of the auxiliary beam 5 is hinged to the head end of the auxiliary beam 5, and the end of the auxiliary beam 5 abuts the bottom panel of the chute head. The auxiliary beam 5 is a straight beam. To prevent rotation, the included angle between the auxiliary beam 5 and the bottom surface of the chute is less than 80° That is, the included angle between the auxiliary beam 5 and the floor of the vibrating ore drawing machine is less than 80°, preferably 77°. The rear section of the main beam 3 is connected to the auxiliary beam 5 in a knuckle shape, a lower cylinder 6 is hinged therebetween, an upper cover 7 is provided above the rear section of the main beam 3, and the inner side of the auxiliary beam 5 is provided There is a rear cover plate 8, that is, the cover plate faces the direction of the well. The upper cover plate 7 and the rear cover plate 8 can be rectangular metal plates, which are welded to the main beam 3 and the auxiliary beam 5, respectively, to prevent smashing in the chute The ore from the ore enters the vibratory ore drawing machine 12 under maintenance to avoid safety accidents. The main beam is preferably a box beam, and the secondary beam is preferably a trough beam. In addition, a lower hook 9 is provided on the well wall of the chute under the cylinder support 2, and a connecting ring 10 is provided on the front section of the main beam 3, and the connecting ring 10 is buckled and connected with the lower hook 9 to connect The main beam 3 is completely and firmly fixed on the chute wall. According to operation needs, multiple groups of this safety protection structure can be combined to form a safety protection shed.

[0018] The safety protection structure can be folded and stretched freely. When not in use, it can be folded and hung on the upper hook 11 with a pawl on the top plate. There is no need for frequent disassembly and assembly. It also solves the problem of avoiding guns. At this time, the front section of the main beam 3 The connecting ring 10 is removed from the lower hook 9 (such as image 3 Shown).
