Description

Technical Field

[0001] This invention relates to the field of robot accessories technology, specifically a special cable for industrial robots. Background Technology

[0002] Robot-specific cables are similar to common cables in daily life, but in terms of performance, robot-specific cables have more stringent requirements, and the requirements for cables equipped with robots used in different fields also vary greatly.

[0003] For pipeline robots, the environment in which they are used is more complex, so the resistance requirements of the cables equipped on the pipeline robots are higher. However, during actual use, the pipeline robot drags the cable along the inner cavity of the pipeline. After the pipeline robot breaks up the sharp objects that are blocking the pipeline, the sharp objects will scratch the dragging cable. In addition, the pressure of the cable on the broken objects will cause the broken objects to re-accumulate in the pipeline, causing secondary blockage. In severe cases, the secondary blockage will prevent the pipeline robot from detaching.

[0004] In view of this, a special cable for industrial robots was designed to solve the above problems. Summary of the Invention

[0008] In a preferred embodiment, the present invention may be further configured as follows: the pipe wall assist mechanism further includes two first bolts fixedly installed on the outer wall of the support plate, a horizontal rail disposed outside the two first bolts and horizontally positioned, a slider movably installed inside the horizontal rail, a second shaft movably installed inside the slider, and a second spring fixedly connected to the inner wall of the horizontal rail and the slider.

[0009] A clamping plate is fixedly installed at the bottom end of the support plate, and a third shaft and a first pulley fixedly installed on the third shaft are movably installed inside the clamping plate.

[0010] The first shaft, the second shaft, and the third shaft are connected to a first transmission belt.

[0011] The dredging mechanism also includes a roller shaft, two ring pads fixedly installed on the roller shaft, a second pulley fixedly installed in the middle of the roller shaft, a second transmission belt connected to the second pulley and the first pulley, and a brush disc installed outside the ring pads.

[0012] In a preferred embodiment, the present invention may be further configured such that the dredging mechanism further includes a crossbar fixedly installed in the base, a sleeve inserted into the other end of the crossbar, a third bolt installed in the sleeve and pressing the crossbar, two rivets installed in the sleeve, and a fixing plate inserted in the sleeve and fixed by the two rivets.

[0013] In a preferred embodiment, the present invention may be further configured such that the pipe wall assist mechanism further includes a first spring fixedly installed in a rectangular slide groove, and the bottom end of the first spring is fixedly installed on the base.

[0014] In a preferred embodiment, the present invention may be further configured such that the cable suspension mechanism further includes a second bolt installed in the base, a washer movably installed outside the second bolt and bearing pressure on the support plate, and a nut installed on the threaded section of the base.

[0015] In a preferred embodiment, the present invention may be further configured such that the cable suspension mechanism further includes a limiting rod inserted inside the housing and a fourth spring disposed outside the limiting rod, wherein the limiting rod is adapted to penetrate into the interior of the pad, and the top end of the fourth spring is adapted to bear pressure on the pad.

[0016] In a preferred embodiment, the present invention may be further configured such that: the base has an insertion hole inside, and the insertion hole is used to provide an effective passage for the free lifting and lowering of the vertical rod.

[0017] In a preferred embodiment, the present invention may be further configured such that the pulley body is provided with protrusions to increase the frictional resistance in contact with the inner wall of the pipe.

[0021] 1. This invention adds a cable suspension mechanism to the section where the pipeline robot connects to the cable, and installs a pipe wall assist mechanism on top of the cable suspension mechanism. When the pipeline robot pulls the cable to move laterally along the inner cavity of the pipeline, the part of the cable that is suspended will not come into contact with the broken dirt, thereby avoiding the risk of the cable being scratched by the sharp dirt after the pipeline robot initially breaks it.

[0022] 2. The present invention installs a sludge removal mechanism on one side of the cable suspension mechanism. The pipe wall assist mechanism that moves along the inner cavity of the pipe provides kinetic energy to the sludge removal mechanism. The dirt broken by the pipe robot is dispersed by two brushes. The dispersed dirt remains in a fluffy state, thereby avoiding wear on the part of the cable that will be dragged on the ground.

[0023] 3. This invention forms a triangular structure by combining the pipe wall assist mechanism and the cable suspension mechanism, and sets up a dredging mechanism to enhance stability on one side of the triangular structure. In this case, the three-dimensional frame can enhance the stability of the pipeline robot climbing along the pipeline and avoid the robot from overturning due to excessive load caused by excessively long cables.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0041] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0042] The following describes, with reference to the accompanying drawings, some embodiments of a special cable for industrial robots provided by the present invention. Example 1:

[0043] Combination Figures 1 to 10 As shown, the present invention provides a special cable for industrial robots, including a cable body 100 and a pipe 500, a pipe wall assist mechanism 200 disposed outside the cable body 100, a cable suspension mechanism 300 disposed on the pipe wall assist mechanism 200, and a sludge removal mechanism 400 disposed on the pipe wall assist mechanism 200. The suspended portion of the cable body 100 is located at the center of the inner cavity of the pipe 500. The pipe wall assist mechanism 200 moves along the top of the inner cavity of the pipe 500, and the cable suspension mechanism 300 moves along the bottom of the inner cavity of the pipe 500. The pipe wall assist mechanism 200 and the cable suspension mechanism 300 form a triangular structure to enhance the stability of the suspended portion of the cable body 100 and facilitate the normal drainage of crushed materials. The sludge removal mechanism 400 is used to enhance the stability of the structure of the pipe wall assist mechanism 200 and the cable suspension mechanism 300 and to loosen the crushed debris.

[0044] The pipe wall assist mechanism 200 includes a support plate 210, a protective cover 220 installed on the top of the support plate 210, a first shaft 230 movably installed inside the protective cover 220, a roller 2301 fixedly installed outside the first shaft 230, two first bolts 250 fixedly installed on the outer wall of the support plate 210, a horizontal rail 2501 arranged outside the two first bolts 250 and horizontally positioned, a slider 2502 movably installed inside the horizontal rail 2501, a second shaft 2504 movably installed inside the slider 2502, and a second spring 2503 fixedly connected to the inner wall of the horizontal rail 2501 and the slider 2502.

[0045] A clamping plate 2101 is fixedly installed at the bottom end of the support plate 210. A third shaft 260 and a first pulley 2601 fixedly installed on the third shaft 260 are movably installed inside the clamping plate 2101.

[0046] The first drive belt 240 is connected to the first shaft 230, the second shaft 2504 and the third shaft 260;

[0047] The support plate 210 has a rectangular groove inside;

[0048] Rectangular blocks are fixedly installed at the top and bottom of the slider 2502, and horizontal grooves are opened at the top and bottom of the horizontal rail 2501, with the rectangular blocks fitting through the horizontal grooves.

[0049] The cable suspension mechanism 300 includes a base 310 movably installed in a rectangular groove, a truss 320 set on a threaded section of the base 310, two vertical rods 3201 installed at both ends of the truss 320, a base 330 movably installed outside the vertical rods 3201, a pad 3302 fixedly installed at the bottom end of the base 330, two housings 3401 movably installed at both ends of the pads 3302, and a pulley 350 movably installed at the bottom end of the housings 3401.

[0050] A third spring 3202 is fixedly connected between the truss 320 and the base 330, and the third spring 3202 is located outside the vertical rod 3201;

[0051] The dredging mechanism 400 also includes a roller 430, two ring pads 4301 fixedly installed on the roller 430, a second pulley 4302 fixedly installed in the middle of the roller 430, a second transmission belt 440 connected to the second pulley 4302 and the first pulley 2601, and a brush disc 450 installed outside the ring pads 4301.

[0052] The brush 450 is made of a wheel and multiple arc-shaped scrapers welded together, and the outer ends of the arc-shaped scrapers are equipped with semi-circular rubber tips.

[0053] When one end of the cable body 100 connected to the pipeline robot passes through the sheath 420 and the support plate 210, the section of the cable body 100 located at the tail of the pipeline robot will be suspended in the air. As the pipeline robot moves along the inner cavity of the pipeline 500, the dirt accumulated inside the pipeline 500 will be broken up by the pipeline robot. The broken dirt will not come into direct contact with the cable body 100. As the sludge removal mechanism 400 is dragged and moves along the bottom of the inner cavity of the pipeline 500, the two driven brushes 450 will loosen the broken dirt inside the inner cavity of the pipeline 500. The loosened dirt will reduce the damage to the dragging part of the cable body 100, thereby ensuring the safety of the cable body 100 during the reciprocating dragging along the inner cavity of the pipeline 500. At the same time, it avoids the problem of secondary accumulation of broken dirt due to the pressure of the cable body 100. Example 2:

[0054] Combination Figures 7 to 10 As shown, based on Embodiment 1, the pipe wall assist mechanism 200 further includes a first spring 2102 fixedly installed in a rectangular slide groove, and the bottom end of the first spring 2102 is fixedly installed on the base 310.

[0055] The cable suspension mechanism 300 also includes a second bolt 3101 installed in the base 310, a washer 3102 movably installed outside the second bolt 3101 and bearing pressure on the support plate 210, and a nut 3103 installed on the threaded section of the base 310; a limiting rod 340 inserted into the housing 3401 and a fourth spring 3402 provided outside the limiting rod 340, wherein the limiting rod 340 is adapted to penetrate into the interior of the pad 3302, and the top end of the fourth spring 3402 is adapted to bear pressure on the pad 3302;

[0056] The base 330 has an insertion hole 3301 inside, and the insertion hole 3301 is used to provide an effective passage for the free lifting and lowering of the vertical rod 3201;

[0057] The pulley 350 has protrusions on its body to increase the frictional resistance to contact with the inner wall of the pipe 500.

[0058] Preferably, both walls of the protective cover 220 are provided with oblique holes, and a section of the first transmission belt 240 is adapted to pass through the oblique holes. The roller 2301 is provided with a corrugated groove on its outside to enhance the frictional force in contact with the top of the inner cavity of the pipe 500, thereby improving the stability of the roller 2301 moving along the inner cavity of the pipe 500.

[0059] In addition, the truss 320 has a U-shaped structure, while the vertical bar 3201 has a T-shaped structure. After assembly, the base 330 and the two outer shells 3401 form a 45-degree angle with the bottom of the inner cavity of the pipe 500, and the two sets of bases 330 and outer shells 3401 are used to provide sufficiently strong support and protection for the support plate 210. Example 3:

[0060] Combination Figure 3 As shown, in the above embodiment, the dredging mechanism 400 further includes a crossbar 410 fixedly installed in the base 310, a sleeve 420 inserted into the other end of the crossbar 410, a third bolt 4201 installed in the sleeve 420 and pressing the crossbar 410, two rivets 4202 installed in the sleeve 420, and a fixing plate 4203 inserted in the sleeve 420 and fixed by the two rivets 4202.

[0061] Preferably, a rubber layer is fixedly installed on the inner wall of the sheath 420 to provide anti-detachment protection for the insertion section of the cable body 100, and a U-shaped slot is provided at the bottom of the fixing plate 4203, and the bottom end of the second transmission belt 440 is located in the U-shaped slot.

[0062] Specifically, the fixing plate 4203, the sheath 420, and the crossbar 410 are in a vertical structure to enhance the stability of the triangular structure tube wall assist mechanism 200 and the cable suspension mechanism 300.

[0063] The working principle and usage process of the present invention are as follows: the cable body 100 is first passed horizontally along the sheath 420 and the support plate 210, and then the end of the cable body 100 passing through the support plate 210 is connected to the pipeline robot.

[0064] Then, the assembled device is delivered to the port of the pipe 500. Next, the cable suspension mechanism 300 is pressed against the pipe wall assist mechanism 200 until the cable suspension mechanism 300 and the pipe wall assist mechanism 200 are retracted to fit the diameter of the pipe 500. Then, the device is pushed horizontally into the pipe 500.

[0065] When the pipeline robot moves along the bottom of the inner cavity of the pipeline 500, the cable body 100 will be pulled by the pipeline robot and the whole device will move. At this time, the part of the cable body 100 that is suspended by the cable suspension mechanism 300 will maintain a safe distance from the pipeline robot. As the pipeline robot passes through the bottom of the inner cavity of the pipeline 500 and breaks up the accumulated dirt, the part of the cable body 100 that is suspended can avoid being scratched by broken and sharp debris.

[0066] As the roller 2301 rotates against the top of the inner cavity of the pipe 500, the first shaft 230 installed inside the roller 2301 drives the first transmission belt 240 to rotate. The combined second shaft 2504 and slider 2502, under the elastic support of the second spring 2503, cause the first transmission belt 240 to be pressurized and tightened at the point where it passes the second shaft 2504. Furthermore, the bottom end of the first transmission belt 240 drives the third shaft 260 and the first pulley 2601. Wheel 2601 drives the second drive belt 440, which in turn drives the second pulley 4302, roller 430, and two ring pads 4301. Two brushes 450 welded to the outside of the two ring pads 4301 break up the debris after it is broken by the pipe robot and transfer it backward until the debris is loose. The loose debris reduces the pressure on the part of the cable body 100 that is dragging on the ground, thereby improving the safety of the cable body 100 during the stretching operation inside the pipe 500.

[0067] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
