Description

Technical Field

[0001] The utility model relates to the technical field of rack rail hanging devices, in particular to an auxiliary rack rail hanging pipeline. Background Art

[0002] The rack-and-rail hoist device is widely used in the hanging of cables and pipelines during the recovery process of the fully-mechanized mining face in coal mines. As the fully-mechanized mining face in coal mines is recovered, the cables and pipelines must be continuously controlled to move forward. During the pulling and moving of the cables and pipelines, the force on the cables and pipelines is often unbalanced, causing the rack-and-rail hoist device to tilt. At the same time, as the working face advances, the cable pipelines often "drag on the ground", causing wear of the cable pipelines, which brings safety hazards to the safe production of the fully-mechanized mining face in coal mines. In addition, the worn cable pipelines need to be replaced in a timely manner, which increases the production and operation costs of coal mines.

[0003] Therefore, we urgently need a device for assisting the rack rail hanging pipe line pulling to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an auxiliary rack rail pipeline hanging line to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary rack rail pipeline, including a rack rail crane, wherein walking wheels are movably arranged on both sides of the outer wall of the rack rail crane, a mobile base is movably connected to the central axis of the walking wheel, a wheel axle fixing plate is movably installed at the middle position of the walking wheel and the mobile base, a connecting seat is installed on one side of the bottom of the mobile base, and is connected with a traction hard connection, a flexible chain is fixedly installed on the surface of the mobile base, a pipeline restraint is fixedly installed on the other end of the flexible chain, and a cable pipeline is arranged on the pipeline restraint; a stabilizing component is arranged between the mobile bases.

[0006] Preferably, the stabilizing assembly includes: a connecting plate fixedly connected between the moving bases.

[0007] Preferably, a wheel seat is fixedly connected to the top of the connecting plate, two groups of wheel seat pin bodies are integrally connected to the wheel seat, and the wheel seat pin bodies are movably connected to a stabilizing wheel via an axis.

[0008] Preferably, the outer wall of the stabilizing wheel contacts the teeth provided below the rack rail hanger, so as to increase the friction between the stabilizing wheel and the rack rail hanger.

[0009] Preferably, a pressure rod is movably connected to the wheel seat, a telescopic end of the pressure rod is movably connected to a buckling plate, and an arc-shaped body is integrally connected to the buckling plate.

[0010] Preferably, an arc-shaped brake pad is fixedly connected to the inner side of the arc-shaped body, one side of the arc-shaped brake pad is movably connected to the wheel seat pin body, and the inner side of the arc-shaped brake pad is in contact with the outer wall of the stabilizing wheel.

[0011] The utility model provides an auxiliary rack rail pipeline hanging line. It has the following beneficial effects:

[0012] (1) The utility model is provided with a traveling wheel, an axle fixing plate, a mobile base, a traction hard connection, a flexible chain, a pipeline restraint, and a connecting seat. The traveling wheel is located in the middle of the rack crane device and is fixed together with the axle fixing plate and the mobile base for lifting the cable pipeline and moving it forward and backward. The traction hard connection is connected to the forward direction of the mobile base through a pin shaft for controlling the traveling distance. The lower part of the mobile base is connected to the pipeline restraint through a flexible chain. The pipeline restraint separates and arranges the cable pipeline and fixes and controls the lifting. As the rack crane moves forward, the cable pipeline on the rack crane can be controlled to move forward and lift, which can effectively solve the problems of wear and unbalanced force of the rack crane pulling the pipeline in the prior art.

[0013] (2) The utility model moves the buckling plate upward to extend the pressure rod, thereby driving the arc brake pad to press against the surface of the stabilizing wheel, thereby increasing the friction between the stabilizing wheel and the arc brake pad, and indirectly increasing the friction between the stabilizing wheel and the teeth provided under the rack crane, thereby reducing the overall forward and backward movement speed of all cable pipelines under the rack crane, and conversely reducing the friction between the stabilizing wheel and the teeth provided under the rack crane, thereby avoiding excessive wear of the cable pipelines due to the movement speed.

[0028] Example 2

[0029] On the basis of Example 1, a preferred embodiment of an auxiliary rack rail pipeline suspension line provided by the utility model is as follows: Figure 1-3 As shown: the stabilizing assembly 10 includes:

[0030] The connecting plate 1001 is fixedly connected between the mobile bases 3;

[0031] The top of the connecting plate 1001 is fixedly connected with a wheel seat 1002, and two sets of wheel seat pin bodies 1003 are integrally connected to the wheel seat 1002. The wheel seat pin body 1003 is movably connected with a stabilizing wheel 1004 through an axis. The outer wall of the stabilizing wheel 1004 is in contact with the teeth provided below the rack rail hanger 8, so as to increase the friction between the stabilizing wheel 1004 and the rack rail hanger 8.

[0032] The wheel seat 1002 is movably connected with a pressing rod 1005, the telescopic end of the pressing rod 1005 is movably connected with a pressing plate 1006, and the pressing plate 1006 is integrally connected with an arc body 1007;

[0033] An arc-shaped brake pad 1008 is fixedly connected to the inner side of the arc-shaped body 1007 , one side of the arc-shaped brake pad 1008 is movably connected to the wheel seat pin body 1003 , and the inner side of the arc-shaped brake pad 1008 is in contact with the outer wall of the stabilizing wheel 1004 .

[0034] Furthermore, in the present embodiment, by bending the buckling plate 1006 upward, the pressure rod 1005 is driven to extend, thereby driving the arc brake pad 1008 to resist the surface of the stabilizing wheel 1004, thereby increasing the friction between the stabilizing wheel 1004 and the arc brake pad 1008, and indirectly increasing the friction between the stabilizing wheel 1004 and the teeth provided under the rack rail hanger 8, thereby reducing the overall forward and backward movement speed of all cable pipelines 9 under the rack rail hanger 8, and conversely, by bending the buckling plate 1006 downward, the pressure rod 1005 is driven to contract, thereby driving the arc brake pad 1008 to release the effect of resisting the surface of the stabilizing wheel 1004, thereby reducing the friction between the stabilizing wheel 1004 and the arc brake pad 1008, and indirectly reducing the friction between the stabilizing wheel 1004 and the teeth provided under the rack rail hanger 8, thereby allowing the overall forward and backward movement of all cable pipelines 9 under the rack rail hanger 8 to be normal.

[0035] When in use, first use the flexible chain 5 and pipeline restraint 6 to fix the cables and pipelines and control their lifting, and then use the walking wheel 1 to control the overall forward and backward movement of all cables and pipelines 9 under the rack crane 8, wherein the traction hard connection 4 is used to control the walking distance of the rack crane 8, and the connecting seat 7 is used to buffer the impact force caused by the rack crane 8 moving too fast; then, by bending the buckling plate 1006 upward, the pressure rod 1005 is extended, thereby driving the arc brake pad 1008 to resist the surface of the stabilizing wheel 1004, thereby increasing the friction between the stabilizing wheel 1004 and the arc brake pad 1008, indirectly This increases the friction between the stabilizing wheel 1004 and the teeth provided under the rack rail hanger 8, thereby slowing down the overall forward and backward movement speed of all cable pipelines 9 under the rack rail hanger 8. Conversely, by bending the buckling plate 1006 downward, the pressure rod 1005 is driven to contract, thereby driving the arc-shaped brake pad 1008 to release the resistance effect on the surface of the stabilizing wheel 1004, thereby reducing the friction between the stabilizing wheel 1004 and the arc-shaped brake pad 1008, indirectly reducing the friction between the stabilizing wheel 1004 and the teeth provided under the rack rail hanger 8, and thereby the overall forward and backward movement of all cable pipelines 9 under the rack rail hanger 8 can be normal.
