Description

Technical Field

[0001] The utility model relates to the technical field of single-track hoists, and specifically refers to a single-track hoist track reversing mechanism. Background Technique

[0002] Single-track hoists are commonly used transportation equipment in underground mines. Due to their strong mobility, fast running speed, large load capacity, safety and reliability, they are often used for the installation and withdrawal of coal mining teams in fully mechanized coal mines in coal mines.

[0003] The track of the single-track hoist is hung on the top of the roadway. When the single-track hoist is arranged underground, there will be a situation where two tracks cross, and it is necessary to reverse the track to ensure smooth operation. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a single-track hoist track reversing mechanism.

[0005] The utility model is realized through the following technical solutions. A single-track hoist track reversing mechanism is provided, which includes a first track and a second track that cross each other, and also includes a fixed frame and a reversing track located below the fixed frame. The reversing track is hinged to the fixed frame through a vertical rotating shaft. A first docking port adapted to the reversing track is provided on the first track, and a second docking port adapted to the reversing track is provided on the second track. A driving mechanism for driving the reversing track to swing between the first docking port and the second docking port is also included; blocking blocks are fixedly connected to the lower end surfaces of both ends of the reversing track, and limiting baffles are fixedly connected to the lower end surfaces of the first track and the second track, and the limiting baffles extend below the reversing track.

[0006] In this solution, the driving mechanism drives the reversing track to swing between the first docking port and the second docking port. When the reversing track is located at the first docking port, the first docking port is filled, thereby realizing the conduction of the first track. When the reversing track is located at the second docking port, the second docking port is filled, thereby realizing the conduction of the second track. When the reversing track swings to the first track or the second track, the blocking blocks at both ends of the reversing track contact the limiting baffles of the first track or the second track, thereby realizing its limit and ensuring the accuracy of the track docking. The limiting baffles play a supporting role for the ends of the reversing track.

[0007] As an optimization, the fixed frame includes a rectangular frame and two diagonal beams connected to the diagonals of the rectangular frame, and the rotating shaft is axially connected to the intersection of the two diagonal beams. In this solution, the rotating shaft is axially connected to the intersection of the two diagonal beams, thereby ensuring the support strength of the rotating shaft and improving the load-bearing capacity of the reversing track.

[0008] As an optimization, the driving mechanism includes a reversing cylinder, one end of the reversing cylinder is hinged to the fixed frame, and the other end is hinged to the reversing track. The reversing cylinder in this solution realizes the swing drive of the reversing track.

[0009] As an optimization, a connecting frame is fixedly connected to the reversing track, and the other end of the reversing cylinder is hinged to the connecting frame. The connecting frame in this solution realizes the connection between the reversing cylinder and the reversing track.

[0010] As an optimization, the connecting frame includes a vertical plate fixedly connected to the upper end of the reversing track and a horizontal plate fixedly connected to the upper end of the vertical plate, and the horizontal plate is located above the fixed frame. When the reversing track stops at the reversing position in this solution, the horizontal plate can be located above the fixed frame. Therefore, if the reversing track falls, the support function can be realized through the horizontal plate to prevent falling and hurting people.

[0011] As an optimization, connecting frames are fixedly connected to both ends of the reversing track. In this solution, connecting frames are arranged at both ends. On the one hand, it can adapt to the on-site installation conditions, facilitate the connection of the reversing cylinder to any connecting frame, and facilitate the on-site layout.

[0012] As an optimization, an inclined surface located below the reversing track is provided on the upper end surface of the limit baffle, and the height of the inclined surface gradually decreases along the direction close to the reversing track. Thus, it is convenient for the reversing track to swing above the limit baffle.

[0013] The beneficial effects of the present invention are as follows: A single-rail crane track reversing mechanism of the present invention can realize the reversing of the cross track, ensure the operation of the single track, and the reversing mechanism has high support strength, can adapt to the operation of a 50-ton single-rail crane, has a reliable and stable structure, strong versatility, and can adapt to various on-site layout methods.

[0023] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation modes.

[0024] As Figures 1 to 7 shown, a single-rail hoist track reversing mechanism of the present utility model includes intersecting first track 8 and second track 9. The first track 8 and the second track 9 have the same height and are of the same type of track. The first track 8 and the second track 9 are hung on the top surface of the roadway, and the single-rail hoist travels on the first track 8 and the second track 9.

[0025] It further includes a fixed frame 1 and a reversing track 2 located below the fixed frame 1. The height and type of the reversing track 2 are the same as those of the first track 8 and the second track 9.

[0026] The fixed frame 1 includes a rectangular frame and two diagonal beams connected to the diagonals of the rectangular frame. The rectangular frame is welded by rectangular tubes, and the diagonal beams can also be made of rectangular tubes, and the two diagonal beams are cross-connected.

[0027] The reversing track 2 is hinged to the fixed frame 1 through a vertical rotating shaft 3. The rotating shaft 3 is fixed at the midpoint of the upper end surface of the reversing track 2, and the rotating shaft 3 is axially connected to the intersection point of the two diagonal beams, thus ensuring the support strength of the rotating shaft and improving the load-bearing capacity of the reversing track.

[0028] The first track 8 is provided with a first docking interface adapted to the reversing track 2, and the length of the first docking interface is the same as the length of the reversing track 2. The second track 9 is provided with a second docking interface adapted to the reversing track 2, and the length of the second docking interface is the same as the length of the reversing track 2.

[0029] It further includes a driving mechanism for driving the reversing track 2 to swing between the first docking interface and the second docking interface; the driving mechanism includes a reversing cylinder 4. The reversing cylinder 4 is arranged above the fixed frame 1. One end of the reversing cylinder 4 is hinged to the fixed frame 1, and the other end is hinged to the reversing track 2, and the hinge shafts are all vertically arranged.

[0030] Specifically, in this embodiment, a connecting frame 5 is fixedly connected to the reversing track 2, and the other end of the reversing cylinder 4 is hinged to the connecting frame 5. The connecting frame 5 includes a vertical plate fixedly connected to the upper end of the reversing track 2 and a horizontal plate fixedly connected to the upper end of the vertical plate. The horizontal plate is located above the fixed frame 1.

[0031] As Figures 1 - 4 shown, the horizontal plate of the connecting frame 5 is located above the fixing frame, and the vertical plate of the connecting frame 5 swings within the triangle formed by two diagonal beams and one side of the rectangular frame. In this embodiment, when the reversing track 2 is connected to the second track 9, one end of the horizontal plate is located directly above the diagonal beam, playing a role in fall protection and facilitating the arrangement of the reversing cylinder 4.

[0032] Both ends of the reversing track 2 are fixedly connected with a connecting frame 5. It can adapt to the on-site installation conditions, facilitate the connection of the reversing cylinder to any connecting frame, and facilitate the on-site arrangement.

[0033] Both lower end faces of the two ends of the reversing track 2 are fixedly connected with a stop block 7. The lower end faces of the two ends of the reversing track 2 are provided with machining planes, and the stop block 7 is fixedly connected to the machining plane, making the lower end of the stop block 17 in this embodiment higher than the lower end of the reversing track 2, without affecting the movement on the single track.

[0034] Both lower end faces of the first track 8 and the second track 9 are fixedly connected with a limit baffle 6. Both lower end faces of the ends of the first track 8 and the second track 9 close to the reversing track 2 are provided with machining planes, and the limit baffle 16 is fixedly connected to the machining plane. The limit baffle 6 extends below the reversing track 2.

[0035] The limit baffle 6 is fixed by bolts, facilitating the on-site arrangement.

[0036] As Figure 7 shown, the upper end face of the limit baffle 6 is provided with an inclined surface located below the reversing track 2, and the height of the inclined surface gradually decreases along the direction close to the reversing track 2.

[0037] The usage method of the present utility model:

[0038] The telescopic movement of the reversing cylinder 4 drives the reversing track 2 to swing between the first docking port and the second docking port. When the reversing track 2 is located at the first docking port, the first docking port is filled, thereby realizing the conduction of the first track 8. When the reversing track 2 is located at the second docking port, the second docking port is filled, thereby realizing the conduction of the second track 9. When the reversing track 2 swings to the first track or the second track, the stop blocks 7 at both ends of the reversing track 2 contact the limit baffles 6 of the first track 8 or the second track 9, thereby realizing its limitation and ensuring the accuracy of the track docking.
