DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second" etc. in the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged in appropriate circumstances, so that the embodiments of the present application described here. In the present application, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" etc. are based on the orientation or positional relationship shown in the accompanying drawings.

[0035] The embodiment of the present invention provides a motor sliding line cable walking device, which can be used for replacing the plug-in and pull-out pin motor at the belt head station of the coal conveyor trestle, and can also be used in other cable laying scenarios, completely solving the problem of cable winding around wheels, eliminating the hidden danger of cable breakage, reducing the workload of manual maintenance, extending the service life of the cable, and reducing the frequency and cost of maintenance and replacement of the cable.

[0036] like Figure 1 As shown, a motor sliding line cable running device includes a main support beam 1, a first support column 2, a second support column 3, a sliding line 4 and a pulley 5.

[0037] Among them, the first pillar 2 and the second pillar 3 are arranged at intervals along the length direction of the main support beam 1, one end of the first pillar 2 and one end of the second pillar 3 are fixedly connected to the main support beam 1, and the two ends of the slide line 4 are fixedly connected to the first pillar 2 and the second pillar 3 respectively. The first pillar 2 and the second pillar 3 are used to fix the slide line 4, providing solid support for the subsequent stable operation of the slide line 4.

[0038] There are multiple pulleys 5 slidably connected to the sliding line 4, and the bottom of each pulley 5 is fixedly connected to a coil 7. The cable 6 is configured to pass through the coil 7 on each pulley 5. One end of the cable 6 is connected to the work station junction box 8, and the other end of the cable 6 is connected to the ground junction box 9.

[0039] For example, the contact surface between the coil 7 and the cable 6 is a smooth surface, which reduces the wear of the cable 6 and the coil 7; the coil 7 is made of plastic because the plastic material has a smaller friction coefficient.

[0040] The embodiment of the present invention connects the slide wire 4 and the cable 6 via the pulley 5, so that the cable 6 can automatically adjust its position following the expansion and contraction of the belt, thereby improving the automation level of the system.

[0041] For example, the main support beam 1 may be made of channel steel, or the support beam on the modified equipment may be used, thereby reducing the equipment cost.

[0042] For example, the first pillar 2 and the second pillar 3 are perpendicular to the main support beam 1, and the heights of the first pillar 2 and the second pillar 3 are the same, so that the sliding line 4 is determined to be a straight line, and the length directions of the sliding line 4 and the main support beam 1 are parallel to each other, ensuring that the sliding line 4 maintains an equal distance from each part of the main support beam 1, so that the cable 6 can be evenly stressed during operation, reducing failures caused by shaking or deviation of the sliding line 4, reducing wear and tear, and extending the service life.

[0043] The embodiment of the present invention ensures the linearity of the slide line 4 by accurately setting the positions of the first support 2 and the second support 3, so that the sliding of the cable 6 is more stable and reliable.

[0044] For example, the first pillar 2 and the second pillar 3 are both made of channel steel, and the first pillar 2, the second pillar 3 are welded to the main support beam 1, which is convenient for construction and modification, and is particularly suitable for equipment modification.

[0045] For example, the distance between the sliding line 4 and the main support beam 1 is greater than the radius of the pulley 5, so that the pulley 5 does not collide with the main support beam 1 when sliding on the sliding line 4. The lengths of the first pillar 2 and the second pillar 3, and the positions where the sliding line 4 is connected to the first pillar 2 and the second pillar 3 should take into account the diameter of the pulley 5. For example, when the lengths of the first pillar 2 and the second pillar 3 are both 10 cm, the two ends of the sliding line 4 are respectively connected to the end of the first pillar 2 away from the main support beam 1 and the end of the second pillar 3 away from the main support beam 1. At this time, the diameter of the pulley 5 shall not be greater than 20 cm, so as to ensure that the pulley 5 does not collide with the main support beam 1 when sliding on the sliding line 4.

[0046] For example, the slide wire 4 can adopt a low-cost steel wire rope, and the two ends of the slide wire 4 are detachably connected to the first pillar 2 and the second pillar 3, so as to facilitate the installation and replacement of the slide wire 4.

[0047] like Figure 2 As shown, for example, the bottom of the first support 2 and the bottom of the second support 3 are both provided with a locking mechanism 10, such as Figure 3 As shown, the locking mechanism 10 includes a locking block 11, a push pin 12 and a spring 13, and both ends of the sliding wire 4 are provided with a plurality of grooves 14 along the length direction.

[0048] Among them, the top of the locking block 11 is fixedly connected to the bottom of the first pillar 2 or the second pillar 3, and a first through hole 15 is arranged on the upper edge of the locking block 11 parallel to the length direction of the sliding line 4. The inner diameter of the first through hole 15 is matched with the outer diameter of the sliding line 4. The sliding line 4 is slidably connected to the first through hole 15, and a step hole is arranged on the upper edge of the locking block 11 perpendicular to the direction of the first through hole 15.

[0049] The step hole includes a second through hole 16 and a third through hole 17 which are connected to each other, wherein the inner diameter of the second through hole 16 is larger than the inner diameter of the third through hole 17, the second through hole 16 is connected to the first through hole 15, and the connection between the second through hole 16 and the third through hole 17 has a step surface.

[0050] A convex surface 18 matching the groove 14 is provided at the top of the ejector pin 12, and a limit ring 121 is provided below the convex surface 18 of the ejector pin 12. The limit ring 121 is located in the second through hole 16. The ejector pin 12 is slidably connected to the third through hole 17. A handle 19 is provided at the bottom of the ejector pin 12. The outer diameter of the handle 19 is greater than the outer diameter of the ejector pin 12. The handle 19 is detachably connected to the bottom of the ejector pin 12, for example, the handle 19 is threadedly connected to the ejector pin 12.

[0051] The spring 13 is located in the second through hole 16 and sleeved on the ejector pin 12 . The top of the spring 13 abuts against the limiting ring 121 , and the bottom of the spring 13 abuts against the step surface.

[0052] The principle of the locking mechanism 10 locking the slide wire 4 is: pull the handle 19 downward, the spring 13 is compressed, one end of the slide wire 4 is passed through the first through hole 15, release the handle 19, and adjust the position of the slide wire 4 along the length direction. When the groove 14 of the slide wire 4 is aligned with the convex surface 18 of the ejector pin 12, the ejector pin 12 moves toward the slide wire 4 under the action of the spring 13, and the convex surface 18 of the ejector pin 12 slides into the groove 14 of the slide wire 4, thereby limiting the slide wire 4 from continuing to move along the length direction, thereby completing the locking of one end of the slide wire 4.

[0053] The locking mechanism 10 of the embodiment of the present invention can quickly lock and release the slide wire 4, thereby facilitating the replacement and installation of the pulley 5.

[0054] like Figure 4 and Figure 5As shown, for example, the pulley 5 includes a roller 20, a wheel frame 21 and a pin 22, the roller 20 is rotatably connected to the wheel frame 21 through the pin 22, the pin 22 is axially provided with a wire passing hole 23, the sliding wire 4 is configured to slide in the wire passing hole 23 of the pin 22, and the top of the wheel frame 21 is detachably connected to the wire passing coil 7, for example, the top of the wheel frame 21 is connected to the wire passing coil 7 through a thread.

[0055] For example, the motor sliding line cable running device also includes a protective plate 24, the top of the protective plate 24 is fixedly connected to the bottom of the main support beam 1, the bottom of the protective plate 24 extends below the lowest point of the cable 6, and the side of the protective plate 24 close to the sliding line 4 is a smooth surface.

[0056] By providing a smooth surface on the protective plate 24, a smooth and unobstructed operating environment is provided for the sliding cable, so that the cable 6 can move naturally and smoothly, greatly reducing friction resistance and improving operating efficiency.

[0057] The motor sliding cable running device of the embodiment of the present invention is used for replacing the plug-in and pull-out pin motor at the belt head station of the coal conveying trestle. Figure 1 As shown, the belt coal pipe guide trough bracket below the workstation body 25 can be used as the main support beam 1, and the first support column 2 and the second support column 3 are welded on the main support beam 1. After the pulley 5 is slidably installed on the slide line 4, the slide line 4 is fixed on the first support column 2 and the second support column 3, and finally the cable 6 is passed through the coil 7 on each pulley 5.

[0058] After the cable of the pin switching motor at the belt head station of the coal conveyor trestle adopts the sliding cable walking device of the embodiment of the present invention, during the switching process, even without supervision, it can safely follow the natural and smooth extension and retraction of the belt, completely eliminating the hidden danger of being hung up by the bracket. After actual operation inspection, it operates normally.

[0059] When the motor sliding cable running device of the embodiment of the present invention is used in other scenarios, it can also be implemented with reference to the above method, which will not be described in detail.

[0060] The motor sliding cable traveling device of the embodiment of the present invention can make the cable 6 retract and automatically adjust its position, avoiding the situation where the cable 6 is entangled on the wheel, reducing the possibility of damage to the cable 6, thereby reducing the repair and replacement costs caused by damage to the cable 6, thereby achieving a reduction in maintenance costs.

[0061] In the motor sliding line cable traveling device of the embodiment of the present invention, the cable 6 is slidably connected to the coil 7, and the pulley 5 is slidably connected to the sliding line 4. During the movement of the cable 6, the friction force applied to the cable 6 is small, so that the cable 6 is less worn during long-term use, reducing the performance degradation and damage caused by wear, thereby extending the service life of the cable 6 and reducing the frequency and cost of maintaining and replacing the cable 6.

[0062] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
