Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for tunneling machines, specifically to an auxiliary installation tool and installation method for a flexible track mechanism used in coal mines. Background Technology

[0002] In the flexible temporary support of coal mine tunneling machines, a type of rubber track with closed-loop steel wire rope is required. Due to the high hardness of the steel wire rope and rubber itself in the internal reinforcement layer, the track rollers have a small diameter. During the installation of the track, a large tension force is required. At the same time, due to the limited space in the coal mine and the equipment, manual installation is required, which is labor-intensive and has low installation efficiency. Summary of the Invention

[0003] In view of this, the present invention provides an auxiliary installation tool and installation method for a flexible tracked mechanism for coal mines, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0004] To achieve the aforementioned objectives, the technical solution adopted by the present invention is as follows: An auxiliary installation fixture for a flexible track mechanism used in coal mines includes a base arranged on opposite sides and a movable block slidably arranged on each side of the base along a sliding direction. Each movable block is threadedly connected to an adjusting member, and one end of the adjusting member passes through the movable block. The auxiliary installation fixture also includes a blocking part respectively disposed on the base on each side and abutting against one end of the adjusting member on the corresponding side, and a connecting rod connected between the moving blocks on both sides. By rotating the adjusting member, the moving block is driven to slide along the sliding direction, thereby causing the connecting rod to move away from or closer to the blocking part.

[0005] In the aforementioned auxiliary installation fixture, optionally, the adjusting component is an adjusting bolt, which extends along the sliding direction.

[0006] In the aforementioned auxiliary installation fixture, optionally, a sliding groove extending along the sliding direction is provided on each side of the base corresponding to the position of the movable block, the movable block is slidably disposed in the sliding groove, and the blocking part is disposed at one end of the sliding groove.

[0007] Optionally, in the aforementioned auxiliary installation fixture, the connecting rod is detachably connected to the movable blocks on both sides.

[0008] Optionally, limiting members are detachably provided at both ends of the connecting rod. The limiting members are used to prevent the connecting rod from detaching from the moving block, and the position of the limiting members on the connecting rod is adjustable to adjust the distance between the bases on both sides.

[0009] Optionally, the two ends of the connecting rod are respectively provided with external threads, the limiting member is a nut that can engage with the external threads, and the moving blocks on both sides are located between the nuts.

[0010] The second technical solution adopted by the present invention is: an installation method for a flexible track mechanism for coal mines, using the auxiliary installation fixtures described above. The flexible track mechanism includes a track frame, a track, multiple idler roller assemblies, and a limiting rod. The track frame includes support rods arranged on opposite sides and a stop rod connected between the two support rods. The two support rods and the stop rod form an accommodating space. The sides of the two support rods facing the accommodating space are provided with guide grooves along the length direction of the support rods. The guide grooves have openings for the idler roller assemblies to enter the guide grooves. The installation method includes: S1. Place the track within the receiving space, and allow the track portion to extend out of the receiving space; S2. Pass a roller assembly through the track and push both ends of the roller assembly into the guide groove from the openings of the guide grooves on both sides; S3. Repeat step S2 until only one idler roller assembly remains; S4. Insert a blocking element into the support rod to prevent all installed idler roller assemblies from sliding out of the guide groove; S5. Fix the bases on both sides of the auxiliary installation fixture to the ends of the support rods on both sides respectively. Then, pass the connecting rod through the moving block on one side, the track and the moving block on the other side in sequence. Rotate the adjusting member to move the connecting rod away from the base, thereby tensioning the track to a certain extent. Then insert the last idler roller assembly into the track and push the last idler roller assembly into the guide groove. S6. Remove the connecting rod and the blocking member, then push all the idler roller assemblies and the track completely into the receiving space. Finally, install a limiting rod between the support rods on both sides, so that the limiting rod and the stop rod are located on both sides of the track. The limiting rod is used to restrict all the idler roller assemblies on the support rods to obtain a flexible track mechanism.

[0011] Optionally, the support rod is provided with a slot corresponding to the position of the limiting rod, and the limiting rod is inserted into the slot.

[0012] Optionally, the base and the blocking part are integrally formed, and the base and the support rod are fixed relative to each other by screw connection between the blocking part and the support rod.

[0013] Optionally, the track is a rubber track.

[0014] Optionally, threaded holes extending along the length of the guide groove are respectively opened on both ends of the last idler assembly, and through holes are opened on the limiting rod corresponding to the positions of the threaded holes. The installation method further includes the step of passing the end of the tension bolt through the through hole and the threaded hole in sequence, and making the end of the tension bolt abut against the idler assembly adjacent to the last idler assembly, wherein the tension bolt is threadedly connected to the threaded hole.

Detailed Implementation

[0019] Referring to the accompanying drawings and specific embodiments, the features and advantages of the auxiliary installation fixture of the present invention and the installation method of installing the flexible track mechanism using the auxiliary installation fixture will be described by way of example below. However, all descriptions should not be construed as limiting the present invention in any way.

[0020] For any single technical feature described or implied in the embodiments submitted herein, or any single technical feature shown or implied in the various drawings, the present invention still operates in any combination or deletion among these technical features or their equivalents without any technical obstacle, and thus these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0022] See Figures 1 to 3 As shown, this embodiment of the invention provides an auxiliary installation fixture for a flexible track mechanism for coal mines, including a base 1 arranged on opposite sides and a movable block 2 slidably arranged on each side of the base 1 along the sliding direction. A sliding groove 5 extending along the sliding direction is opened on each side of the base 1 at the position corresponding to the movable block 2, and the movable block 2 is slidably arranged in the sliding groove 5.

[0023] Each movable block 2 is threadedly connected to an adjusting member 3, and one end of the adjusting member 3 passes through the movable block 2. As can be seen from the figure, each adjusting member 3 extends along the sliding direction. Optionally, the adjusting member 3 can be an adjusting bolt that extends along the sliding direction.

[0024] The auxiliary installation fixture also includes a blocking part 4, which is respectively set on the base 1 on each side and abuts against one end of the corresponding side adjustment part 3. The blocking part 4 is set at one end of the slide groove 5, and one end of the adjusting bolt passes through the moving block 2 and abuts against the blocking part 4 on the corresponding side.

[0025] The auxiliary installation fixture also includes a connecting rod 6 connected between the two movable blocks 2. By rotating the adjusting bolt, the movable block 2 is driven to slide in the sliding direction, thereby causing the connecting rod 6 to move away from or closer to the blocking part 4.

[0026] Alternatively, the blocking part 4 may be integrally formed with the base 1.

[0027] In some alternative embodiments, the connecting rod 6 is detachably connected to the two side moving blocks 2. Limiting members 7 are detachably provided at both ends of the connecting rod 6. The limiting members 7 are used to prevent the connecting rod 6 from disengaging from the moving blocks 2. The position of the limiting members 7 on the connecting rod 6 is adjustable to adjust the distance between the two side bases 1 to accommodate tracks of different widths.

[0028] Optionally, the two ends of the connecting rod 6 are respectively provided with external threads, the limiting member 7 is a nut that can cooperate with the external threads of the connecting rod 6, the two moving blocks 2 are located between the nuts, and through holes are opened on the moving blocks 2, through which the connecting rod 6 passes.

[0029] The above-mentioned auxiliary installation tooling is used to assist in the installation of the flexible track mechanism, which can be used on flexible temporary support equipment in coal mines.

[0030] like Figure 15 As shown, the flexible track mechanism includes a track frame 9, a track 8, multiple idler roller assemblies 10, and a limiting rod 11.

[0031] See also Figure 4 and Figure 5 The track frame 9 includes support rods 91 arranged on opposite sides and a stop bar 92 connected between the two support rods 91. The two support rods 91 and the stop bar 92 form a receiving space 93. The two support rods 91 facing the receiving space 93 have guide grooves 12 along the length of the support rods 91. The guide groove 12 has an opening that communicates with the outside. The opening is located at the end of the guide groove 12 away from the stop bar 92. The opening is used to allow the idler roller assembly 10 to enter the guide groove 12.

[0032] Optionally, the ends of the two support rods 1 away from the stop bar 92 are provided with through holes that pass through the upper surface and the guide groove, and the ends of the two support rods 1 away from the stop bar 92 are also provided with slots 15.

[0033] Track 8 uses rubber tracks, which are a type of ring track with a closed-loop steel wire rope inner reinforcement layer.

[0034] The following details the installation method of the flexible track mechanism using the aforementioned auxiliary installation fixtures. This installation method includes the following steps: 1. Prepare the track frame, such as Figure 4 and Figure 5 This positions the track frame stop bar 92 on the left side.

[0035] 2. Place track 8 flat in the receiving space 93, and make part of track 8 extend out of the receiving space.

[0036] III. See Figure 6 and Figure 7 A roller assembly 10 is passed through the track 8, and the two ends of the roller assembly 10 are pushed into the guide grooves 12 from the openings of the guide grooves 12 on both sides.

[0037] IV. See Figure 8 and Figure 9 Repeat step three until the last idler assembly remains. Insert the blocking member 13 into the through hole reserved on the support rod 91. The blocking member 13 is used to prevent all the installed idler assemblies 10 from sliding out of the guide groove 12.

[0038] At this stage, due to the high tension of the tracks, it is difficult to manually install the last idler assembly in the remaining track space. Installing the last idler assembly using the aforementioned auxiliary installation fixtures significantly reduces labor intensity.

[0039] V. See also Figure 10 and Figure 11 The two blocking parts 4 on both sides of the auxiliary installation fixture are fixed to the ends of the two support rods 91 with screws to fix the base 1 and the support rods 91 relative to each other. The height of the base 1 and the blocking parts 4 is lower than the height of the guide groove 12 to avoid interference from the blocking parts 4 and the base 1 when the last idler roller assembly is installed.

[0040] Then, the connecting rod 6 passes through the moving block 2 on one side, the track 8 and the moving block 2 on the other side in sequence, and then the limiting piece 7 is installed on both ends of the connecting rod 6 to prevent the connecting rod 6 from detaching from the moving block 2 during operation.

[0041] VI. See also Figure 12 and Figure 13 Rotate the adjusting component 3 to move the moving block 2 away from the base 1 (the moving block 2 moves to the right), which in turn drives the connecting rod 6 to move away from the base 1, so that the track is tensioned to a certain extent. Then, the last idler assembly passes through the track on the left side of the connecting rod 6 and pushes the last idler assembly into the guide groove 12.

[0042] VII. See also Figure 14 and Figure 15 Remove the connecting rod 6 and the blocking member 13, then push all the idler roller assemblies and tracks completely into the receiving space 93. Finally, insert the limiting rod 11 into the slot 15 of the support rods 91 on both sides, so that the limiting rod 11 and the stop rod 92 are located on both sides of the track 8. The limiting rod 11 is used to restrict all the idler roller assemblies 10 to the support rods 91, thus obtaining the flexible track mechanism.

[0043] During the installation of flexible track mechanisms, the use of this auxiliary installation fixture effectively reduces the tension force during track installation, shortens the tensioning stroke, and improves installation efficiency. Furthermore, the fixture's compact design adapts to the limited space conditions in underground coal mines. The adjustable width between the bases accommodates tracks of varying widths. Using this fixture significantly reduces the labor intensity of manual installation, improves installation accuracy and safety, and enables rapid and accurate installation of rubber tracks.

[0044] Using this auxiliary installation tool can not only reduce the manual labor intensity during track installation, but also improve the efficiency of track installation and replacement.

[0045] The idlers in the idler assembly of this flexible track mechanism can all rotate around their own axis, and there is a gap between the idlers of two adjacent idler assemblies, so that the rotation of the idler is not interfered with by the adjacent idlers.

[0046] In some alternative embodiments, after the last idler assembly is installed, the end of the last idler assembly abuts against the limiting rod, and the ends of two adjacent idler assemblies abut against each other in the remaining idler assemblies. A stop can be selectively provided between the end of the last idler assembly and the end of an adjacent idler assembly, so that all idler assemblies can be stably placed in the guide groove.

[0047] In some alternative embodiments, threaded holes are provided at both ends of the last idler roller assembly, and through holes are provided on the limiting rod corresponding to the positions of the threaded holes. After the last idler roller assembly and the limiting rod are installed, as follows: Figure 16 The tensioning bolt that can mate with the threaded hole is inserted into the through hole of the limit rod and screwed into the threaded hole of the last idler assembly. The end of the tensioning bolt 14 is made to abut against the end of the idler assembly adjacent to the last idler assembly. By rotating the tensioning bolt 14, the distance between the last idler assembly and the adjacent idler assembly is adjusted, thereby adjusting the tension of the track and ensuring that all idler assemblies are stable in the guide groove.

[0048] The aforementioned flexible track mechanism can be used on temporary support equipment for coal mine tunneling machines to form a shield-type temporary support system. This flexible track mechanism can be used on the top shield that contacts the roadway roof, or on the side shield that contacts the roadway sidewalls. This shield-type temporary support system combines the flexibility of tracks with the increased load-bearing capacity provided by the idler roller assembly, achieving a balance of rigidity and flexibility. It not only dynamically conforms well to complex and irregular roadway roofs and sidewalls, improving support stability, but also provides stronger support strength. During the tunneling machine's movement, the tracks of the flexible track mechanism contact the roof and / or sidewalls, utilizing the friction between the tracks and the roof / sidewalls to drive the tracks, allowing the shield-type temporary support system to move along with the tunneling machine even without power.

For example, they can refer to direct connection or indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
