[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0025] Combine the following Figures 1 to 5 The invention describes a mining cable hanging tool.

[0026] like Figures 1 to 5 As shown, the mining cable hanging tool provided by the embodiment of the present invention includes a support rod 1 and a support arm device.

[0027] Specifically, the support arm device is arranged at the end of the support rod 1 to accommodate the support cable. The other end of the support rod 1 is used as the hand-held portion 13. When working, the other end of the support rod 1 is manually held to work without the need for complex tools and the operator does not need to climb high places, thereby reducing safety risks.

[0028] The support arm device includes a pair of support arms 2 and a rotation locking mechanism, one end of the support arm 2 is rotatably connected to the support rod 1, and the rotation axis of the support arm 2 relative to the support rod 1 is perpendicular to the axis of the support rod 1. The other end of the support arm 2 is a free end, and the angle between the pair of support arms 2 can be adjusted by rotating the pair of support arms 2 relative to the support rod 1.

[0029] The rotation locking mechanism is disposed between the support arm 2 and the support rod 1 , and the rotation locking mechanism can be switched between an unlocked state and a locked state.

[0030] When the rotation locking mechanism is switched to the unlocked state, the pair of support arms 2 can rotate relative to the support rod 1, and the angle between the pair of support arms 2 can be adjusted as needed. When the rotation locking mechanism is switched to the locked state, the support arm 2 is relatively fixed to the support rod 1, and the angle between the pair of support arms 2 is fixed.

[0031] With such arrangement, the angle between the pair of support arms 2 can be adjusted by making the pair of support arms 2 rotate relative to each other. The angles between the pair of support arms 2 are different, and the opening sizes of the support arm devices (that is, the distances between the free ends of the pair of support arms 2) are different, so that the space between the pair of support arms 2 can accommodate cables of different diameters, thereby being able to adapt to the stable lifting of cables of different diameters so that cables of different diameters can be hung on hooks at target positions. It has strong versatility and solves the problem in the related art that the cable hanging support rod cannot meet the hanging requirements of cables of different diameters.

[0032] It should be noted that, in order to increase the stability of the cable when lifting it, an anti-skid layer can be provided on the surfaces of the pair of support arms 2 that are close to each other, so as to increase the friction between the cable and the support arm 2 and prevent the cable from slipping. The design of the hand-held portion 13 at the end of the support rod 1 needs to comply with the principles of ergonomics to facilitate the operator's holding and operation, and increase the comfort and stability of holding. An anti-skid rubber sleeve can be provided on the hand-held portion 13, and an anti-skid texture can be provided on the outer surface of the anti-skid rubber sleeve to increase the friction resistance of the hand-held portion 13 and increase the reliability of holding.

[0033] In an embodiment of the present invention, the rotation locking mechanism includes a rotating body 3 and a locking portion 4. A rotating body 3 is correspondingly arranged for each support arm 2. The rotating body 3 is relatively fixed to the support arm 2. The rotating body 3 is rotationally connected to the support rod 1. The rotation axis of the rotating body 3 relative to the support rod 1 coincides with the rotation axis of the support arm 2 relative to the support rod 1. That is to say, the rotating body 3 and the support arm 2 can rotate synchronously relative to the support rod 1.

[0034] A plurality of gear teeth are arranged on the rotating body 3, and the plurality of gear teeth are arranged along the circumference of the rotating body 3. Figure 2 The rotating bodies 3 corresponding to the pair of support arms 2 can be meshed and driven. When a force is applied to one of the support arms 2 to rotate the support arm 2 relative to the support rod 1, the other support arm 2 will rotate in the opposite direction by the same angle under the meshing and driving action of the pair of rotating bodies 3.

[0035] The locking portion 4 can be switched between a locked position and an unlocked position. When the locking portion 4 is switched to the unlocked position, the locking portion 4 is separated from any one of the rotating bodies 3. At this time, the locking portion 4 will not interfere with the rotation of any one of the rotating bodies 3, and the relative position of the pair of support arms 2 can be adjusted as needed, corresponding to the unlocked state of the rotation locking mechanism. When the locking portion 4 is switched to the locked position, the locking portion 4 abuts against at least one of the rotating bodies 3. At this time, the locking portion 4 can limit the rotation of the rotating body 3, so that the relative position of the pair of support arms 2 can no longer be adjusted, so that the relative position of the pair of support arms 2 is stable, corresponding to the locked state of the rotation locking mechanism.

[0036] In this embodiment, the locking part 4 is slidably connected to the support rod 1, and the sliding direction of the locking part 4 relative to the support rod 1 is parallel to the rotation direction of the support arm 2 relative to the support rod 1. The locking part 4 switches between the unlocked position and the locked position by sliding.

[0037] The groove between two adjacent gear teeth on the rotating body 3 is called a tooth groove, and each rotating body 3 has a plurality of tooth grooves.

[0038] The locking portion 4 has two protruding teeth, such as Figure 2 As shown, when the locking part 4 slides to the locking position, one convex tooth of the locking part 4 is located in the tooth groove of one of the rotating bodies 3, and the other convex tooth of the locking part 4 is located in the tooth groove of the other rotating body 3. At this time, the two convex teeth of the locking part 4 interact with the gear teeth of the two rotating bodies 3 respectively, and the rotation of the two rotating bodies 3 can be restricted at the same time.

[0039] It should be noted that the locking portion 4 can only slide back and forth relative to the support rod 1, and cannot rotate relative to the support rod 1. Moreover, there is a certain damping between the locking portion 4 and the support rod 1. When the locking portion 4 is not subjected to external force, the locking portion 4 and the support rod 1 are relatively fixed. Only when a certain force is applied to the locking portion 4, can the locking portion 4 slide relative to the support rod 1.

[0040] In the embodiment of the present invention, the mining cable hanging tool further includes a barb arm 5 , which is arranged on the support rod 1 , and the barb arm 5 and the support rod 1 are located on the same side of the pair of support arms 2 .

[0041] The end of the barb arm 5 close to the support arm 2 is the first end of the barb arm 5, and the end of the barb arm 5 away from the support arm 2 is the second end of the barb arm 5. The distance between the second end of the barb arm 5 and the support rod 1 is greater than the distance between the first end of the barb arm 5 and the support rod 1. Figure 1 The distance between the second end of the barb arm 5 and the support rod 1 serves as the opening of the accommodation space between the barb arm 5 and the support rod 1. When in use, the barb arm 5 of the mining cable hanging tool provided in this embodiment can also be used to hook the cable above the height of the target position according to the working environment, lift the cable upward, and hang the cable on the hook at the target position.

[0042] In a further embodiment, the barb arm 5 may be configured to be rotatable relative to the support rod 1 to adjust the distance between the second end of the barb arm 5 and the support rod 1 to achieve hooking of cables of different diameters.

[0043] In some embodiments, the barb arm 5 may be provided with a corresponding rotation locking structure to independently control the rotation angle of the barb arm 5 relative to the support rod 1 .

[0044] In other embodiments, the first end of the barb arm 5 is fixed relative to one of the rotating bodies 3, and the barb arm 5 can rotate synchronously with the rotating body 3 and the support arm 2. The rotation adjustment and locking of the barb arm 5 can be achieved through the rotation locking mechanism of the support arm device.

[0045] It should be noted that the opening direction of the support arm device is opposite to the opening direction of the space between the barb arm 5 and the support rod 1. The support arm device is mainly suitable for lifting the cable below the height of the target position to hang the cable on the hook at the target position. The barb arm 5 is mainly suitable for hooking and lifting the cable above the height of the target position to hang the cable on the hook at the target position. The mining cable hanging tool with both the support arm device and the barb arm 5 has strong adaptability to the working environment.

[0046] In the embodiment of the present invention, the mining cable hanging tool further includes a side support arm 6 and a sliding locking mechanism.

[0047] The end of the side arm 6 close to the support arm 2 is the first end of the side arm 6, and the end of the side arm 6 away from the support arm 2 is the second end of the side arm 6. The distance between the second end of the side arm 6 and the support rod 1 is smaller than the distance between the first end of the side arm 6 and the support rod 1. Figure 1 The distance between the first end of the side arm 6 and the support rod 1 is used as the opening of the accommodation space between the side arm 6 and the support rod 1, and the opening direction of the accommodation space between the side arm 6 and the support rod 1 is the same as the opening direction of the support arm device. When in use, the side arm 6 can also be used to lift the cable.

[0048] The side arm 6 is slidably connected to the support rod 1, and the sliding direction of the side arm 6 relative to the support rod 1 is parallel to the axis of the support rod 1. By sliding the side arm 6 relative to the support rod 1 along the axis of the support rod 1, the position of the side arm 6 on the support rod 1 can be adjusted, that is, the distance between the side arm 6 and the hand-held portion 13 of the support rod 1 can be adjusted, which can be suitable for lifting at different heights.

[0049] In addition, during operation, the side support arm 6 and the support arm device can also lift the cable at the same time. That is to say, the mining cable hanging tool provided in this embodiment can lift two cables at the same time. During specific use, the position of the side support arm 6 on the support rod 1 can be adjusted according to the height difference between the two hooks corresponding to the two cables, so that the distance between the side support arm 6 and the support arm device is consistent with the height difference between the above-mentioned two hooks.

[0050] The sliding movement and position locking of the side support arm 6 on the support rod 1 are achieved by a sliding locking mechanism.

[0051] The sliding locking mechanism is provided between the side arm 6 and the support rod 1, and the sliding locking mechanism can be switched between an unlocked state and a locked state. When the sliding locking mechanism is switched to the unlocked state, the side arm 6 can slide back and forth relative to the support rod 1, and the position of the side arm 6 on the support rod 1 can be adjusted. When the sliding locking mechanism is switched to the locked state, the side arm 6 is relatively fixed to the support rod 1, and the position of the side arm 6 can be ensured to be stable.

[0052] In this embodiment, the mining cable hanging tool also includes a slide bar 7, which is arranged inside the support rod 1, and the axis of the slide bar 7 is parallel to the axis of the support rod 1, and the slide bar 7 can slide back and forth relative to the support rod 1 along the axis direction of the support rod 1. A slide groove 8 is arranged on the support rod 1, and the length direction of the slide groove 8 is parallel to the axis direction of the support rod 1. The end of the side arm 6 passes through the slide groove 8 and is fixedly connected to the slide bar 7, and the side arm 6 and the slide bar 7 can slide synchronously relative to the support rod 1.

[0053] At this time, the sliding locking mechanism includes a clip 9 and a slot 10. The clip 9 is arranged on the slide rod 7. The clip 9 can only rotate relative to the slide rod 7 along the circumferential direction of the support rod 1. The clip 9 cannot slide relative to the slide rod 7 along the axial direction of the support rod 1.

[0054] Specifically, for the connection structure between the clamping member 9 and the slide bar 7, an annular groove can be provided on the slide bar 7, and the clamping member 9 is connected to the clamping ring 16, and the clamping member 9 and the clamping ring 16 are fixedly connected together, such as Figure 4 The snap ring 16 is sleeved on the outside of the slide bar 7 and embedded in the annular groove. The snap ring 16 can rotate relative to the slide bar 7 along the circumference of the slide bar 7. The interaction between the snap ring 16 and the side wall of the annular groove can limit the snap ring 16 from sliding along the axial direction of the slide bar 7.

[0055] The card slot 10 is arranged on the side wall of the slide slot 8, referring to Figure 3 . The clip 9 can reciprocate between the unlocking position and the locking position. When the clip 9 is rotated to the unlocking position, the clip 9 is located in the slide groove 8. At this time, the clip 9 is located outside the slot 10, and the clip 9 can slide relative to the support rod 1 along the axial direction of the support rod 1, corresponding to the unlocking state of the sliding locking mechanism. When the clip 9 is rotated to the locking position, the clip 9 is located in the slot 10. At this time, the clip 9 cannot slide relative to the support rod 1 along the axial direction of the support rod 1, corresponding to the locking state of the sliding locking mechanism.

[0056] When the side arm 6 slides to the point where the clamping piece 9 and the slot 10 are located on the same cross section of the support rod 1, a force along the circumferential direction of the support rod 1 can be applied to the side arm 6 or the clamping piece 9, so that the side arm 6 and the clamping piece 9 rotate along the circumferential direction of the support rod 1, and the clamping piece 9 enters the slot 10. Through the interaction between the clamping piece 9 and the slot 10, the clamping piece 9 can be restricted from sliding along the axial direction of the support rod 1, that is, the side arm 6 can be restricted from sliding along the axial direction of the support rod 1, so as to achieve the locking of the position of the side arm 6 on the support rod 1. When the position of the side arm 6 needs to be adjusted, a force along the circumferential direction of the support rod 1 can be applied to the side arm 6 or the clamping piece 9, so that the side arm 6 and the clamping piece 9 rotate along the circumferential direction of the support rod 1, and the clamping piece 9 is disengaged from the slot 10.

[0057] There are a plurality of slots 10, which are spaced apart along the axis of the support rod 1. When the clamping member 9 enters different slots 10, the side arm 6 can be fixed at different positions.

[0058] In the embodiment of the present invention, the support rod 1 is configured to have a length-adjustable structure.

[0059] In some embodiments, the length of the support rod 1 can be telescopically adjusted. During operation, the length of the support rod 1 can be adjusted according to the height of the hook at the target position to avoid operational inconveniences caused by the length of the support rod 1 being too long or too short.

[0060] Specifically, the support rod 1 includes at least two first rod sections, the axes of the first rod sections coincide, and the first rod sections are sleeved together. The support arm device is arranged at the end of the innermost first rod section, and correspondingly, the outermost first rod section is used for hand-holding.

[0061] Of the two adjacent first rods, the one located outside is the outer rod 11, and the one located inside is the inner rod 12. One end of the outer rod 11 close to the support arm device is threadedly connected to one end of the inner rod 12 away from the support arm device.

[0062] In a specific embodiment, the inner diameters of the outer rod 11 at each position close to the support arm device are equal, that is, the inner side wall of the outer rod 11 at the end close to the support arm device is a cylindrical surface. The outer diameter of the inner rod 12 at the end away from the support arm device gradually increases in the direction away from the support arm device, that is, the outer surface of the inner rod 12 at the end away from the support arm device is a truncated cone, such as Figure 5 shown.

[0063] An internal thread 14 is provided at one end of the outer rod body 11 close to the support arm device, and the diameter of the internal thread 14 is equal at each position in the axial direction of the outer rod body 11. An external thread 15 is provided at one end of the inner rod body 12 away from the support arm device, and the diameter of the external thread 15 is different at each position in the axial direction of the inner rod body 12, and the maximum diameter of the external thread 15 is greater than the diameter of the internal thread 14, and the minimum diameter of the external thread 15 is smaller than the diameter of the internal thread 14.

[0064] The inner rod body 12 is pulled out from the inner rod body 11, and the small end of the external thread 15 on the inner rod body 12 is first matched with the internal thread 14 on the outer rod body 11, and the inner rod body 12 is rotated so that the larger diameter position of the external thread 15 is gradually screwed with the internal thread 14. As the larger diameter position of the external thread 15 is screwed with the internal thread 14, the fit between the internal thread 14 and the external thread 15 becomes tighter and tighter, and the inner rod body 12 and the outer rod body 11 can be tightly connected together.

[0065] When the length of the support rod 1 needs to be shortened, the inner rod body 12 can be rotated in the opposite direction to disconnect the outer thread 15 on the inner rod body 12 from the inner thread 14 on the outer rod body 11 , and the inner rod body 12 can be retracted into the inner part of the outer rod body 11 .

[0066] It should be noted that when the mining cable hanging tooling needs to be stored and transported, the first rod bodies of each section can be disconnected, so that the inner rod bodies 12 of each section can be retracted into the corresponding outer rod bodies 11, shortening the length of the support rod 1 and reducing the occupied space.

[0067] In other embodiments, the support rod 1 is configured as a structure in which multiple sections of the rod are hinged.

[0068] Specifically, the support rod 1 includes a plurality of second rod sections and an angle control mechanism, any two adjacent second rod sections are rotatably connected, the axis of relative rotation of any two adjacent second rod sections is perpendicular to the axis of the second rod section, and the support arm device is arranged at the end of the second rod section at the endmost portion. By adjusting the angle between two adjacent second rod sections, the overall length of the support rod 1 can be adjusted, which is more flexible and the shape and length of the support rod 1 can be adjusted according to the working environment. Moreover, when it is necessary to store and transport the mining cable hanging tooling, the second rod sections can be rotated to overlap each other, and the support rod 1 can be folded to reduce the occupied space.

[0069] The angle control between two adjacent second rod sections can be achieved by relying on an angle control mechanism. Any two adjacent second rod sections are correspondingly provided with an angle control mechanism, which is used to control the relative angle between the two second rod sections.

[0070] In some embodiments, the angle control mechanism is configured as a damping structure located between two adjacent second rod sections.

[0071] In other embodiments, the angle control mechanism is configured as a structure of a driving member such as a motor. When the motor is controlled to operate, the motor can drive two adjacent second rod sections to rotate relative to each other. When the motor is controlled to stop operating, the two adjacent second rod sections can stop rotating relative to each other, and the two adjacent second rod sections can remain relatively fixed. When the angle between the two adjacent second rod sections is controlled, the support rod 1 is electrically controlled.

[0072] The material of the support rod 1 can be but not limited to high-strength lightweight alloy materials such as aluminum alloy, to ensure that the support rod 1 has high strength and rigidity and reduces weight, so that the operator can carry it with him and operate it at any time.

[0073] In some embodiments of the present invention, a pressure sensor and an alarm are also provided on the support arm device, and both the pressure sensor and the alarm are electrically connected to the control device. The pressure sensor is used to detect the pressure of the cable on the support arm 2. When the pressure value detected by the pressure sensor is greater than the preset pressure value, the alarm sounds an alarm to remind the operator of the risk of cable overweight.
