Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a martier tail protective curtain comprises a cross bar 1, a protective chain 2, a limiting chain 3, a connecting chain 4, a base 5 and a vertical column 6.

As shown in figure 1, the cross rod 1 adopts a telescopic rod, and the end part of the cross rod 1 can be lapped on a Martil tail or other components in actual use. A plurality of protection chains 2 are slidably mounted on the cross rod 1, the protection chains 2 are made of iron chains, hanging rings 21 are arranged at the upper ends of the protection chains 2, and the hanging rings 21 are sleeved on the cross rod 1. The protective chain 2 close to the end part of the telescopic rod is fixedly connected with the end part of the telescopic rod.

As shown in fig. 1, the guard chain 2 hangs down naturally. A spacing chain 3 is arranged between two adjacent protective chains 2. The limiting chain 3 is connected to the upper end of the protection chain 2. The lower ends of all the guard chains 2 are connected by a connecting chain 4. The connecting chain 4 is an iron chain or a rope. The lower end of the protection chain 2 is provided with a hanging ring 22, and the connecting chain 4 penetrates through all the hanging rings 22. In practice, the first end of the connecting chain 4 is fixed to the upright 6 and the second end is fixed to a martier tail or the like.

As shown in fig. 1, a column 6 is arranged on a base 5; the cross rod 1 is installed on the stand 6, and the counter weight 11 is arranged on the cross rod 1, and the counter weight 11 and the protection chain 2 are respectively located on two sides of the stand 6.

As shown in fig. 1, in practical application, the martier tail protective curtain of the present invention can be placed in dangerous areas such as martier tail, and can keep personnel out of the dangerous areas, so as to perform the functions of protection and warning, and the safety is good, the cross rod 1 and the protective chain 2 can be made of materials discarded in mines, and the cost is low.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
