DETAILED DESCRIPTION

(4) The technical solutions of the present invention are further described ingrate detail through the following examples with reference to the accompanying drawings.

EXAMPLE

(5) In the example, the present invention provides a rust removing device for an elevator guide rail. As shown in FIGS. 1 and 2, the rust removing device includes a support 1 and a U-shaped rust removal rack 3. The rust removal rack is connected to the support by a hold-down mechanism. The hold-down mechanism includes a fixing rack 2 having a U-shaped cross section. The rust removal rack is fixed between two sides at a front end of the fixing rack by using bolts. Bumper blocks 11 are further disposed between the fixing rack and two sides of the rust removal rack, which are made of rubber. The hold-down mechanism further includes a spring 10 disposed within the fixing rack. One end of the spring is disposed with a first spring seat 8 located on a bottom surface of the fixing rack. The other end of the spring is disposed with a second spring seat 9 located on a back part of the rust removal rack.

(6) An adjusting mechanism is further disposed between the spring and the fixing rack, which includes a bolt chair 6 disposed at a bottom part of the fixing rack and having an adjusting bolt 7 mounted thereon. The adjusting bolt passes through the fixing rack, and then a front end of the adjusting bolt is connected to a back surface of the first spring seat 8.

(7) The rust removal rack has a U-shaped cross section. A layer of shoe mat 4 is disposed on the U-shaped inner concave surface, and has the rust removal layer 5 being configured thereon. A top end of the rust removal rack is disposed with fastening platforms 12 on two sides thereof respectively. The rust removal layer protrudes out of the top end of the rust removal rack, and is placed on the fastening platforms, and then is tightly pressed onto the fastening platforms by hold-down plates 13 disposed on the fastening platforms. Then, the hold-down plates are fixed on the fastening platforms by fastening bolts. A bottom end of the rust removal rack is disposed with L-shaped fastening plates 14 at two sides thereof respectively. The rust removal layer protrudes out of the bottom end of the rust removal rack and is attached to the fastening plates, and then is pressed onto the fastening plates by hold-down plates 13 disposed on the fastening plates. The hold-down plates are fixed on the fastening plates by fastening bolts. The rust removal layer is made of an abrasive paper, which may be further made of a cotton gauze, an oilstone, an abrasive disc, or a cutting disc, besides abrasive paper. The shoe mat is made of a metal material, and may also be made of a non-metal material, such as nylon, plastic, or felt.

(8) In the example, the rust removing device is mounted on a top part of a roller guide shoe of a lift car, or may be mounted at other positions, for example, on a top part of an upper guide shoe, on a bottom part of a lower guide shoe of the lift car. In addition, the rust removing device is mounted on a counterpoise, for example, on a top part of an upper beam of the counterpoise, on a bottom part of a lower beam of the counterpoise, on a top part of an upper roller guide shoe of the counterpoise, or on a bottom part of a lower roller guide shoe of the counterpoise.

(9) What are described in the specification are preferred examples of the present invention, and the examples are only used for describing the technical solution of the present invention instead of limiting the present invention. Technical solutions that can be made by persons skilled in the art according to the present invention through logic analysis, ratiocination or limited experiment should all fall within the scope of the present invention.

(10) Although the present invention adopts terms such as support, fixing rack, rust removal rack, shoe lining, or rust removal layer, it is also possible for the present invention to use other terms. The above terms are merely intended to describe and demonstrate the essence of the present invention easily and conveniently, which cannot be considered as an additional restriction on the present invention.
