Description

Technical Field

[0001] The utility model relates to the technical field of mine monorail hoists, in particular to a monorail hoist track hanging device. Background Art

[0002] The monorail hoist track transportation system is one of the most important auxiliary transportation equipment systems in coal mines. The installation quality of the monorail hoist track directly determines the running speed and safety of the monorail hoist locomotive in the monorail hoist track transportation system. The monorail hoist track is formed by connecting several I-beam monorails in succession and hanging them on a roadway or other fixed structures by a monorail hoist track hanging device. Currently, common monorail hoist track hanging devices, such as the articulated rail joint for suspending the rail beam profile steel rail joint of a suspended monorail transportation system disclosed in the Chinese patent document with the publication number CN1255569A and a light rail track connection structure of a monorail hoist system disclosed in the Chinese patent document with the authorization announcement number CN204185126U, have the common feature that they are suspended on the roadway by bolts and chains. There are obvious "V"-shaped gaps at the joints of adjacent two tracks. The corresponding technical problems brought about are as follows: During the construction process, it is difficult to master the installation angle of the bolts on the hanging installation foundation. If the installation angle is not good, it will affect the overall installation quality of the monorail hoist; when using chains for suspension, it is difficult to adjust when the chains are loose during installation and operation. The hanging height is large, and during operation, the force on a single chain is likely to occur, affecting the running safety; the obvious "V"-shaped gaps at the joints of adjacent two tracks cause a relatively large swing amplitude of the track when the monorail hoist locomotive passes through, affecting the running speed and efficiency of the monorail hoist locomotive and easily damaging the driving wheels of the monorail hoist locomotive, affecting its service life. In addition, due to the limitation of the structure of the existing monorail hoist track hanging device, its maximum load-bearing capacity is limited. Therefore, it is necessary to further improve the existing monorail hoist track hanging device to meet the requirements of the coal mine monorail hoist transportation system.

[0021] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0022] (Embodiment 1)

[0023] See Figures 1 to 6 , the single-rail hanging device of this embodiment mainly consists of a fixed clamping member 1, a balance connecting member 2, a main connecting shaft 3, a tension adjuster 4, an anchor fixing seat 5 and an anchor rod 6.

[0024] The fixed clamping member 1 is used to fixedly connect the upper parts of two adjacent single rails to realize the fixed connection of the single rails. As a specific implementation manner, in this embodiment, the fixed clamping member 1 includes two fixed clamping plates 11 and several sets of fixed bolts 12; as Figure 2 shown, the fixed clamping plate 11 is integrally composed of a main body part located below and a semi-circular connecting part located above. Several fixed screw holes 11-1 are provided on the main body part of the fixed clamping plate 11, and a connecting shaft hole 11-2 is provided on the semi-circular connecting part of the fixed clamping plate 11. The number of sets of fixed bolts 12 is the same as the number of fixed screw holes 11-1 of the fixed clamping plate 11. Refer to Figure 5 and Figure 6 , during use, two fixed clamping plates 11 are respectively arranged on the front and rear sides of the connection part of the connecting wing plates 101-1 of two adjacent single rails 101, and the two fixed clamping plates 11 are fixedly connected to the connecting wing plates 101-1 of two adjacent single rails 101 through several sets of fixed bolts 12; the lower ends of two adjacent single rails 101 are fixedly connected by a bottom connecting member 102 in the prior art, so as to realize the fixed connection between two adjacent single rails 101 of the single-rail hanging track.

[0025] Adopting the fixed clamping member 1 of this embodiment in cooperation with the bottom connecting member 102 in the prior art to realize the fixed connection between two adjacent single rails 101 can make the gap between two adjacent single rails 101 extremely small, as Figure 5As shown, it effectively solves the technical problems in the prior art that in similar devices, there is an obvious "V"-shaped gap at the connection of adjacent single rails, which correspondingly leads to a relatively large swing amplitude of the track when the single-rail hoist locomotive passes through, affects the running speed and efficiency of the single-rail hoist locomotive, and is likely to damage the driving wheels of the single-rail hoist locomotive and affect its service life.

[0026] The balance connecting member 2 is used for connecting and transitioning. As a specific implementation manner, in this embodiment, the balance connecting member 2 includes two oppositely arranged balance plates 21 that are integrally arc-shaped and provided with connecting screw holes 21-1, two connecting bolts 22 arranged on the two balance plates 21 in cooperation with the connecting screw holes 21-1 of the balance plates 21, a connecting ring 23 sleeved on each of the two connecting bolts 22, and an internal fixing connecting member 24 fixedly arranged between the middle positions of the two balance plates 21. The lower part of the internal fixing connecting member 24 is integrally arc-shaped and provided with a shaft hole 24-1, as Figure 4 shown; the internal fixing connecting member 24 is connected to the middle positions of the two balance plates 21 by welding or integral casting at its upper part.

[0027] The integrally arc-shaped lower part of the internal fixing connecting member 24 of the balance connecting member 2 is placed between the semi-circular connecting parts of the two fixing clamping plates 11 of the fixing clamping member 1, and the shaft hole 24-1 of the internal fixing connecting member 24 is in cooperation with the connecting shaft holes 11-2 of the two fixing clamping plates 11, and is movably connected through the main connecting shaft 3. The main connecting shaft 3 is provided with a limit pin 31 to prevent the separation of the movable connection between the internal fixing connecting member 24 of the balance connecting member 2 and the two fixing clamping plates 11 of the fixing clamping member 1.

[0028] The tension adjuster 4 is a commercially available part, and the tension adjuster is also commonly known as a shackle; there are two tension adjusters 4, and one end of each of the two tension adjusters 4 is respectively sleeved with a connecting ring 23 of the balance connecting member 2.

[0029] The bolt fixing seat 5 includes a seat body 51 in the shape of a rectangular plate member and two connecting ears 52 integrally or fixedly arranged on both sides below the seat body 51. The upper ends of the two tension adjusters 4 are respectively connected to one connecting ear 52, so that the distance between the balance connecting member 2 and the bolt fixing seat 5 can be adjusted and connected through the two tension adjusters 4. The bolt 6 is used for the fixed installation of the single-rail hoist track hanging device in this embodiment on the hanging installation base 103 of the single-rail hoist track in the coal mine; the bolt 6 is a screw rod, and one screw rod 6 is rotatably arranged on each side of the seat body 51 of the bolt fixing seat 5 in threaded cooperation. Preferably, the two bolts 6 are vertically arranged on the bolt fixing seat 5.

[0030] The single-rail hoist track hanging device of this embodiment realizes the connection between the balance connecting piece 2 and the bolt fixing seat 5 by using two tension regulators 4. Compared with the chain connection method commonly used in the prior art, since the distance of the tension regulator 4 itself is adjustable and the length is relatively short, it can effectively solve the technical problems existing in the chain suspension method in the prior art, such as difficult adjustment when the chain is loose, large hanging height, and easy influence on the running safety due to the force on a single chain during operation. Moreover, in this embodiment, by setting a special bolt fixing seat, it can effectively solve the technical problems in the prior art that it is difficult to master the installation angle of the bolt on the hanging installation base 103, and if the installation angle is not good, it will affect the overall installation quality of the single-rail hoist.

[0031] In addition, through the improved design of the overall structure of the single-rail hoist track hanging device of this embodiment, on the premise of the same single-rail specification, the maximum load-bearing capacity of the single-rail hoist track formed by connecting the single-rail hoist track hanging device of this embodiment can be increased by about 30%, and the overall track is stable when the single-rail hoist locomotive passes, which can increase the running speed of the single-rail hoist locomotive by about 30%.

[0032] The above embodiments are descriptions of the specific implementation manners of the present invention, rather than limitations on the present invention. Those skilled in the relevant technical fields can also make various transformations and changes to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
