[0002] Monorail crane has the advantages of large carrying capacity, high operating efficiency, small tunnel space occupation, flexible operation and high applicability. It has become the first choice equipment for auxiliary transportation in mines to realize the transportation of people and materials.

[0003] Monorail locomotives run on a single track suspended above the underground tunnel of a mine. The installation quality of the track directly determines the operating status of the locomotive. Existing track connections and fixations are mostly carried out using forged ring chains. The ring chains have good connection stiffness and good degrees of freedom, which facilitates track installation and fixation under complex and multiple working conditions. However, due to the limitations of the size of each ring in the ring chain, the use of multi-ring chains makes it difficult to achieve continuous adjustment of the track height, which directly affects the flatness of the track installation and, in turn, the operating quality of the locomotive. Therefore, designing a simple adjustable connection device for track installation to achieve continuous adjustment of the track is of great significance to improving the quality of track installation.

DETAILED DESCRIPTION

[0020] The specific contents of the present invention are further described below:

[0021] The utility model discloses a monorail crane track height-adjustable connecting device, which is used for adjusting the installation height of the monorail crane track.

[0022] Specific as Figure 1 As shown, the system comprises a fixed anchor rod 2 and a track connector 11, with an adjustable connecting device 6 disposed between the fixed anchor rod 2 and the track connector 11. The fixed anchor rod 2 can also be an anchor cable structure for connection to the top of the tunnel. The length-adjustable devices are arranged in pairs on either side of a swing member 5, the lower middle portion of which is hingedly connected to the track connector 11.

[0023] At least two groups of anchor rods 2 fix a group of tunnel roof 1, and the tunnel roof is close to the tunnel top. Specifically, a plurality of anchor rod holes are provided on the tunnel roof 1, and the anchor rods 2 are passed through the tunnel roof 1 and fixed using nuts.

[0024] A hanging hole plate 3 is provided at the lower part of the tunnel roof 1, and a positioning hole plate is provided above the hanging hole plate 3. The positioning hole plate and the hanging hole plate are parallel to each other, and a pair of hanging holes are provided on the hanging hole plate 3, and the positioning hole plate is provided with bolt positioning holes.

[0025] The hanging orifice plate 3 is fixed on the tunnel roof 1 , specifically, the positioning orifice plate and the hanging orifice plate 3 are fixed on the lower hanging plate, and the lower hanging plate is welded to the tunnel roof 1 .

[0026] A length-adjustable device is provided in the hanging hole, the lower portion of the length-adjustable device is hingedly connected to the swing member 5 , and the swing member 5 is connected to the track connector 11 .

[0027] The length-adjustable device of the present device includes a bolt at the top, a fixing cylinder 8 and two hinged hole plates 10. The top of the bolt hangs down from the hanging hole, and the hexagonal end of the bolt is embedded in the bolt positioning hole of the positioning hole plate. The upper part of the fixing cylinder 8 is provided with an internal thread and cooperates with the thread. Two hinged hole plates 10 are arranged on the outside of the fixing cylinder 8. Through holes are provided on the two hinged hole plates 10, and pins are passed through the through holes to connect with the swinging member 5.
