Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to the figure 1, for the utility model discloses a stirring station cement bin cat ladder, including cement bin body 1 and the support frame 11 of fixed connection on cement bin body 1 bottom, 1 lateral wall fixedly connected with vertical ladder 2 of cement bin body, 2 fixedly connected with of vertical ladder protect the cage 3, fixedly connected with rail guard 12 on the periphery side of 1 up end of cement bin body. The guard rail 12 is used for protecting an operator who gets on the upper end surface of the cement bin body 1.

Referring to fig. 2, the vertical ladder 2 includes a vertically arranged mounting rod 21 and a plurality of cross rods 22 fixedly connected to the mounting rod 21, a first through groove 211 is formed on the upper side wall of the mounting rod 21, and anti-skid lines are arranged on the cross rods 22. The anti-slip pattern is beneficial to reducing the slipping condition of the operator when using the vertical ladder 2.

Protect cage 3 including the support montant 32 and a plurality of five vertical settings along supporting montant 32 length direction horizontal fixed connection support ring 31 on montant 32, support montant 32 array distribution on support ring 31, it has protecting band 4 to protect the outside encirclement of cage 3, support montant 32 including the logical groove montant 322 that is located support ring 31 intermediate position, two spouts 3211 montant 321 and the friction montant 323 of symmetric distribution, it has second through groove 3221 to open on the one side of protecting band 4 just to lead to groove montant 322, it has spout 3211 to open on the one side of protecting band 4 just to slide the montant, fixedly connected with montant rubber pad 3231 is just in the one side of protecting band 4 just to friction montant 323.

Referring to fig. 3, the protective belt 4 is a metal protective belt with a certain elasticity, one end of the protective belt 4 is fixedly connected with a limiting ring 41, the protective belt 4 passes through the limiting ring 41 and enters the protective cage 3 through a second through groove 3221 to be connected with a connecting belt 45, the protective belt 4 is over against a pulley 42 fixedly connected to the position of the vertical rod 321 of the sliding groove 3211, and the protective belt 4 is over against a protective rubber pad 43 fixedly connected to the position of the vertical rod 323 of the friction. The pulley 42 and the chute 3211 are matched to slide, so that the friction force between the protective belt 4 and the protective cage 3 when an operator uses the vertical ladder 2 can be reduced, and the friction force between the protective belt 4 and the protective cage 3 when the operator accidentally drops can be increased by the protective rubber pad 43 and the vertical rod rubber pad 3231.

One end of the protective belt 4 extending into the protective cage 3 is fixedly connected with a safety belt 44. The safety belt can slow down the impact force when the operator falls, thereby reducing the injury to the operator.

The implementation principle of the embodiment is as follows:

before the cement bin ladder of the mixing plant is used, one end of the protective belt 4, which is not provided with the limiting ring 41, winds around the protective cage 3 for a circle, penetrates through the first through groove 211, then penetrates through the limiting ring 41, then enters the protective cage 3 through the second through groove 3221, is fixedly connected with the safety belt 44, the pulley 42 is right opposite to the sliding groove 3211, and the protective rubber gasket 43 is right opposite to the vertical rod rubber gasket 3231.

When the cement bin ladder stand of the mixing plant is used, an operator wears the safety belt 44, confirms that the pulley 42 is opposite to the chute 3211, and confirms that the protective rubber pad 43 is opposite to the vertical rod rubber pad 3231, and then climbs upwards through the vertical ladder stand 2.

When an operator accidentally drops by using the ladder, the protective belt 4 is tensioned, the protective rubber pad 43 is tightly abutted to the vertical rod rubber pad 3231, the falling speed of the operator is reduced by friction between the protective rubber pad 43 and the vertical rod rubber pad 3231, meanwhile, the safety belt 44 can reduce stress on the human body, absorb part of impact energy and reduce injury to the operator.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
