Description

Technical Field

[0001] The utility model relates to the technical field of underground mobile tools, in particular to a double-supporting-wheel overhead passenger hanger with a rope-catching wheel. Background Art

[0002] The overhead passenger hanger, also known as the monkey hanger, is an auxiliary equipment that enables underground mine workers to go up and down in and out of the mine tunnel. It generally uses a movable wire rope arranged in the mine tunnel as a power source to drive the hanger and the workers riding on the hanger to move. In the past, the hanger structure was relatively simple. During operation, problems such as the lifting wheel slipping off the wire rope or the hanger itself breaking its axle may occur. These problems not only affect the normal operation of the equipment, but may also cause serious harm to the passengers. Therefore, a passenger hanger that can effectively prevent the lifting wheel from slipping off the wire rope is currently needed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] Example:

[0023] Reference Figure 1 The present embodiment provides a double-supporting-wheel aerial passenger hanger with a rope-catching wheel; it comprises a vertically placed column 1; a top plate 2 is mounted on the upper top of the column 1; a crossbeam 3 intersecting the column 1 is mounted in the middle of the column 1; cantilevered positioning rods 4 are provided on the left and right end sides of the crossbeam 3; a pair of longitudinally arranged positioning plates 5 are provided on the positioning rods 4, and a rope-catching roller 6 is rotatably mounted on the protruding end of the positioning rods 4; two main rollers 7 are rotatably provided between the positioning plates 5; the wheel diameter of the rope-catching roller 6 is smaller than that of the main rollers 7; the rope-catching roller 6 is located between the two main rollers 7; a protective vertical plate 8 is also provided on the positioning plate 5; the outer end side of the rope-catching roller 6 is arranged opposite to the protective vertical plate 8.

[0024] A plurality of reinforcing ribs 9 are provided between the outer side wall of the column 1 and the top plate 2 .

[0025] A clamping block 10 is provided on the outer wall of the middle part of the column 1; a positioning groove 10A is opened on the front end face of the clamping block 10; the middle part of the beam 3 is installed in the positioning groove 10A for installation; U-shaped bolts 11 are provided on the upper and lower sides of the clamping block 10; the middle part of the U-shaped bolt 11 is clamped on the column 1, and its two protruding ends are arranged over the beam 3 installed in the positioning groove 10A; a pressure plate 12 is also provided between the corresponding protruding ends of the upper and lower U-shaped bolts 11, and the pressure plate 12 is pressed on the front end face of the beam 3 by a nut.

[0026] The axes of the rope catching roller 6 and the two main rollers 7 are located at the same horizontal height; the two positioning plates 5 have the same structure; the two main rollers 7 are symmetrically arranged between the positioning plates 5 with the axes of the rope catching roller 6 and the positioning rod 4 as the center.

[0027] A stepped shaft 13 with small ends and a large middle is passed through the two positioning plates 5; threaded sections are provided at both ends of the stepped shaft 13 extending out of the positioning plates 5, and the stepped shaft 13 is installed on the positioning plates 5 through nuts and washers; a bearing 14 is installed at the position of the stepped shaft 13 between the two positioning plates 5; the main roller 7 is installed on the bearing 14.

[0028] The protective vertical plate 8 and the positioning plate 5 form a closed horizontal area, and the rope catching roller 6 and the two main rollers 7 are all located in the closed horizontal area.

[0029] The shape of the protective plate 8 is an isosceles trapezoidal structure similar to the cross-section of a C-shaped steel structure. Its long sides are formed into two hook-shaped extensions, which are bolted to the ends of the positioning plate 5 facing the column 1. The short sides of the isosceles trapezoidal structure are shorter than the length of the positioning plate.
