Technical Field

[0001] The present application relates to the technical field of pipeline installation, and in particular to an auxiliary mechanism for installing mine ventilation pipelines. Background Art

[0002] Mine ventilation ducts are pipes installed in mine tunnels for ventilation deep in the mine. In order to reduce the obstruction of the pipeline to normal traffic, the ventilation duct and other pipes are usually suspended and installed on the top of the tunnel. During installation, due to installation errors and other reasons, the two adjacent pipes need to be adjusted in position when connected to complete the docking installation. Since the mine ventilation duct is installed at the top of the tunnel, the docking operation is inconvenient, and because it is at a high place, it is not convenient to use auxiliary tools such as hydraulic cylinders and jacks.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] See also Figure 1 and Figure 2 , is an auxiliary mechanism for installing a mine ventilation duct disclosed in an embodiment of the present application, comprising a rope-drawing rod 1, a thread is arranged on the outer side of the rope-drawing rod 1, one end of the rope-drawing rod 1 is fixedly connected to a pipe-drawing steel cable 2, a first end of the pipe-drawing steel cable 2 is fixedly installed on one end of the rope-drawing rod 1, and a second end is detachably connected to the rope-drawing rod 1, a rope-binding tube 3 is slidably sleeved on the outer side of the rope-drawing rod 1, a pipe-drawing worm gear 41 and a pipe-drawing worm 42 are rotatably installed on one end of the rope-binding tube 3 away from the pipe-drawing steel cable 2, the pipe-drawing worm gear 41 is threadedly connected to the rope-drawing rod 1, the pipe-drawing worm 42 is meshed with the pipe-drawing worm gear 41, and a rotating handle 43 is installed on the pipe-drawing worm 42.

[0032] Specifically, the detachable end of the pipe-drawing steel cable 2 passes through the bolt hole of the ventilation duct connecting flange and is fixed on the rope-drawing rod 1. When the pipe-drawing worm 42 is rotated, the pipe-drawing worm gear 41 rotates accordingly, and the rotation of the rope-drawing rod 1 is restricted by the pipe-drawing steel cable 2 installed on the flange, thereby causing the rope-drawing rod 1 to move axially, pulling the pipe-drawing steel cable 2 into the rope-binding tube 3, so that the end of the rope-binding tube 3 abuts against the fixed end of the ventilation duct, and the other ventilation duct is pulled to the docking position of the duct through the pipe-drawing steel cable 2.

[0033] In this way, the pipe pulling cable 2 pulls the ventilation ducts closer to each other by rotating the pipe pulling worm 42, and the docking position correction of the ventilation ducts is completed by two auxiliary mechanisms connected to different bolt holes. The structure is simple and easy to operate, and it is convenient to use in inconvenient locations such as the top of a mine.

[0034] In some feasible embodiments, the rope pull rod 1 is a threaded rod, the tube pull steel cable 2 is a steel wire rope having a diameter smaller than the bolt hole of the ventilation duct connecting flange, the rope binding tube 3 is a round tube having an inner diameter the same as the outer diameter of the rope pull rod 1, an installation box is fixedly installed at the end of the rope binding tube 3, the tube pull worm gear 41 and the tube pull worm 42 are installed in the installation box, and the rotating handle 43 is a Z-shaped bending part.

[0035] As a specific implementation of an auxiliary mechanism for installing a mine ventilation duct provided in the application, the middle portion of the rotating handle 43 is retractable.

[0036] In general, the function of the rotating handle 43 is to reduce the rotating force by increasing the lever arm. By providing a retractable rotating handle 43, it is easier to use and also easier to use when the operating space is small.

[0037] Furthermore, a one-way wrench 431 is fixedly mounted on the end of the rotating handle 43 , and the one-way wrench 431 is detachably mounted on the pulling tube worm 42 .

[0038] It should be understood that the one-way wrench 431 only applies force in one direction. When the space is small and it is inconvenient to operate, the one-way wrench 431 can be reciprocated to facilitate the rotation of the pull tube worm 42.

[0039] In some feasible ways, the middle of the rotating handle 43 is set as a sleeve, and the two ends of the sleeve are L-shaped rods. The sleeve is provided with fixing bolts to facilitate fixing after extension. The one-way wrench 431 is a common ratchet wrench structure, and the end surface of the pull tube worm 42 is provided with a socket, and the one-way wrench 431 is inserted into the socket.

[0040] As another specific implementation of the auxiliary mechanism for installing a mine ventilation duct provided in the application, please refer to Figure 3 A mounting column 11 is threadedly connected to one end of the pull rope rod 1 near the pull tube steel cable 2. Wire grooves are provided on both sides of the mounting column 11. Both ends of the pull tube steel cable 2 are embedded in the wire grooves. Both ends of the pull tube steel cable 2 are fixedly connected to the limited position blocks 21.

[0041] In combination with specific usage scenarios, the installation of the free end of the tube-drawing steel cable 2 is facilitated by providing the installation column 11 and the limit block 21 .

[0042] Furthermore, the rope-pulling rod 1 is tubular, and is provided with an internal thread, and the mounting column 11 is threadedly connected to the internal thread.

[0043] It should be understood that by setting the internal thread, the installation column 11 can be moved inside the pull rope rod 1, which is convenient for adjusting the leakage length of the pull pipe steel cable 2 after installation, reducing the rotation amount of the pull pipe worm gear 41, improving work efficiency, and also convenient for adjusting the pull pipe steel cable 2 to adapt to ventilation ducts with different offset distances.

[0044] As a specific implementation of the auxiliary mechanism for installing a mine ventilation duct provided in the application, please refer to Figure 1 A positioning piece 31 is provided at one end of the rope-binding tube 3 close to the tube-drawing steel cable 2, and the end of the positioning piece 31 away from the rope-binding tube 3 is a cylindrical end. When in use, the cylindrical end is inserted into the bolt hole of the flange connected to the pipeline.

[0045] It should be understood that by providing the positioning member 31 , one end of the rope-binding tube 3 is fixed on the ventilation duct, so as to facilitate the rotation operation of the rotating handle 43 .

[0046] In some feasible embodiments, the cylindrical end is a cylinder with a diameter no greater than a bolt hole diameter of a flange connected to the ventilation duct, and is inserted into the bolt hole of the flange connected to the ventilation duct when in use.

[0047] As a specific implementation of the auxiliary mechanism for installing a mine ventilation duct provided in the application, please refer to Figure 2 A spline hole 411 is provided at the center of the pull-rope worm gear 41 , a spline tube 412 is installed in the spline hole 411 , and the spline tube 412 is threadedly connected to the pull-rope rod 1 .

[0048] It should be understood that by providing the spline tube 412, the pull tube worm gear 41 can be sleeved on the rope pull rod 1, and then the connection with the rope pull rod 1 is established by rotating the spline tube 412, thereby reducing the need to rotate the entire part when installing the pull tube worm gear 41. Instead, only the spline tube 412 needs to be rotated, which facilitates the operation.

[0049] As a specific implementation of an auxiliary mechanism for installing a mine ventilation duct provided in the application, the rope binding tube 3 is fixedly connected with a gripping handle.

[0050] It should be understood that by providing the holding handle, it is convenient to hold the rope-binding tube 3 in place when the rotating handle 43 is rotated.

[0051] In some feasible embodiments, the gripping handle may be set as a grip or patterns may be engraved on the surface of the rope-binding tube 3 to increase gripping friction.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
