Description

Technical Field

[0001] The present invention relates to the technical field of traction force detection, and in particular to a maximum traction force detection device and a detection method for a rubber-tyred mining vehicle. Background Art

[0002] Rubber-tyred vehicles are usually made of steel or aluminum. A load-bearing platform or cargo box is usually installed on the four rubber wheels to facilitate the transportation of various items. They are generally used for coal mine transportation. In the production of rubber-tyred vehicles, in order to ensure the reliability of the product, traction tests are often required to determine the various indicators of the rubber-tyred vehicle, such as maximum traction and other data.

[0003] The current traction detection device for rubber-tyred mining vehicles connects one end of the traction rope to a tension sensor and the other end to the vehicle body, then starts the vehicle body to move and pulls the traction rope, and detects the maximum traction of the vehicle through the tension sensor. However, when a tension sensor is generally used for detection, the tension sensor is easily damaged by excessive tension of the traction rope, and the rubber-tyred vehicle will shake during normal driving. Therefore, the detection device in the prior art cannot simulate the tension of the traction rope on the force-bearing end of the tension sensor in a shaking state. Moreover, during the detection process, if the traction rope is unhooked from the vehicle body or breaks due to excessive force, the traction rope will bounce off and injure the staff because the tension disappears instantly. Summary of the invention

[0018] The present invention also discloses a detection method of a maximum traction force detection device for a mining rubber-tyred vehicle, comprising the following steps:

[0019] S1: First, fix the traction rope on the rubber-tyred vehicle, then start the rubber-tyred vehicle to move and pull the traction rope. The traction rope will pull multiple cables through the connecting plate, and then pull multiple tension sensors, so that the traction force generated by the rubber-tyred vehicle is divided into multiple strands and acts on several tension sensors respectively, and then the traction force of the rubber-tyred vehicle is detected by the several tension sensors;

[0020] S2: When the rubber-tyred vehicle pulls the traction rope, the traction rope will drive the connecting plate and the bracket to move. At this time, the transmission assembly can drive the screw rod to rotate back and forth, and the screw rod will push the mounting plate up and down through the movable seat and the movable column, so that the support seat and the tension sensor on the mounting plate will shake up and down, thereby simulating the traction force of the rubber-tyred vehicle in the shaking state caused by the vibration of the traction rope and the tension sensor during driving;

[0021] S3: When the traction rope breaks due to shaking or excessive force, the tension of the traction rope will disappear instantly. At this time, the first spring will drive the sliding column to slide downward instantly, and the extrusion seat will move down to abut against the fixed seat. The traction rope is pressed into the pressure groove through the pressure strip, and the extrusion seat and the fixed seat are fixed after abutting against each other through the locking assembly, so that the broken traction rope can be clamped and fixed;

[0022] S4: If the rubber-tyred vehicle deviates to the left or right during movement, the traction rope will be driven to deviate to the left or right sides. The traction rope will stick to the first roller and squeeze the first roller to slide to both sides. When the traction rope deviates to the up or down direction, it will stick to the second roller and squeeze the second roller to rotate to the up or down direction, thereby providing buffer protection for the deviated traction rope.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. First, connect the traction assembly to the rubber-wheeled vehicle, then start the rubber-wheeled vehicle to move and pull the traction assembly. The traction assembly will pull a number of cables through the connecting plate, and then pull a number of tension sensors through the cables. At this time, the large traction force generated by the rubber-wheeled vehicle will be dispersed into multiple smaller traction forces and act on each tension sensor respectively. The sum of the traction forces detected by the multiple tension sensors can detect the traction force of the rubber-wheeled vehicle, thereby solving the problem in the prior art that the traction force generated by the rubber-wheeled vehicle is too large and all acts on one tension sensor, causing damage to the sensor;

[0025] 2. Through the transmission assembly, when the rubber-wheeled vehicle is pulling the traction assembly, the support, tooth groove, first rotating column, second rotating column, third rotating column, incomplete gear, first complete gear, second complete gear, active bevel gear, torsion spring, driven bevel gear and belt can drive the screw rod to rotate back and forth, and then can continue to push the mounting plate up and down through the movable seat and movable column, thereby driving the support seat and tension sensor on the mounting plate to shake, simulating the traction force when the traction rope and the connection end of the tension sensor shake due to vibration when the rubber-wheeled vehicle is moving, thereby improving the accuracy of the detection data;

[0026] 3. Through the provided clamping assembly, when the traction rope is unhooked from the rubber-wheeled vehicle or is broken due to excessive tension during the detection process, the tension of the traction rope will disappear instantly. At this time, the provided first spring will drive the sliding column to move downward, and the extrusion seat and the fixed seat will be abutted against each other. The traction rope will be pressed into the pressure groove through the pressure strip, so that the traction rope that is instantly broken or detached can be fixed, and the extrusion seat and the fixed seat that are abutted against each other are fixed together through the provided locking assembly, further improving the stability of the extrusion seat and the fixed seat in fixing the traction rope, thereby preventing the traction rope from instantly breaking and bouncing around to hit the workers and causing injuries;

[0027] 4. Through the set protection components, when the rubber-wheeled vehicle drives the traction rope to deviate, if it deviates to the left or right, the traction rope will stick to the first roller and squeeze the first roller to slide on the support plate, and when the traction rope deviates up or down, the traction rope will stick to the second roller and squeeze the second roller to flip up and down, thereby blocking and buffering the deviated traction rope, preventing the traction rope from being worn due to excessive bending angle of the contact end with the tension sensor caused by the deviation.

DETAILED DESCRIPTION

[0045] 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 described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0046] like Figures 1 to 3 As shown, this embodiment proposes a maximum traction force detection device for a mining rubber-wheeled vehicle, including a detection platform 1, a detection mechanism, a shaking component and a clamping component. The detection mechanism is arranged on the top of the detection platform 1, and the shaking component is arranged between the detection platform 1 and the mounting plate 2. The shaking component can drive the mounting plate 2 to shake along the vertical direction of the detection platform 1 when the traction component is pulled. The clamping component is arranged on the top of the detection platform 1 to fix the traction component that has broken;

[0047] First, connect the traction component to the rubber-tyred vehicle, start the movement of the rubber-tyred vehicle, and through the detection mechanism that is set, the generated large traction force can be divided into multiple smaller traction forces to act on the detection mechanism, so as to prevent the detection mechanism from being damaged by excessive force. In the process of the rubber-tyred vehicle pulling the traction component, the detection mechanism can be driven to shake up and down through the set shaking component, thereby simulating the traction force of the traction rope 801 and the connection end of the tension sensor 301 shaking due to vibration when the rubber-tyred vehicle moves, thereby improving the accuracy of the detection data. In addition, when the traction rope 801 is unhooked from the rubber-tyred vehicle or breaks due to excessive tension during the detection process, the tension of the traction rope 801 will disappear instantly. At this time, the broken traction rope 801 can be clamped and fixed through the set clamping component, so as to prevent the traction rope 801 from breaking instantly and bouncing around to hit the workers and causing injuries.

[0048] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig.13 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the detection mechanism includes a mounting plate 2 arranged at the edge of one side of the top of the detection platform 1, a plurality of support seats 3 arranged on the top of the mounting plate 2, a tension sensor 301 arranged on the side wall of the support seat 3, a cable 302 arranged at the force-bearing end of the tension sensor 301, a connecting plate 4 arranged between the plurality of cables 302, and a traction component arranged on the surface of the connecting plate 4;

[0049] The traction assembly includes a first torsion spring shaft 7 rotatably arranged on the side of the connecting plate 4 away from the cable 302, a drum 8 sleeved outside the first torsion spring shaft 7, and a traction rope 801 arranged on the drum 8;

[0050] The traction rope 801 can be stored by the arranged reel 8. When the traction force of the rubber-wheeled vehicle needs to be tested, the end of the traction rope 801 away from the testing platform 1 is first connected to the rubber-wheeled vehicle through a hook, and then the rubber-wheeled vehicle is started to move and pull the traction rope 801. The traction rope 801 is pulled out of the reel 8 and then pulls multiple tension sensors 301 through the connecting plate 4 and a plurality of cables 302, so that the larger traction force generated by the traction rope 801 can be divided into multiple smaller traction forces acting on each tension sensor 301 respectively. The traction force of the rubber-wheeled vehicle can be detected by the sum of the traction forces detected by the multiple tension sensors 301, so as to prevent the sensor from being damaged due to excessive traction force on the tension sensor 301 when only one tension sensor 301 is used for testing. When the test is completed, the traction rope 801 is separated from the rubber-wheeled vehicle. At this time, the force on the first torsion spring shaft 7 is released, which will drive the reel 8 to reverse and rewind the traction rope 801 again.

[0051] Among them, an insert sleeve 5 is provided at the end of the cable 302 away from the tension sensor 301, and a block 501 is slidably connected to the side wall of the insert sleeve 5, and a third spring 502 is connected between the block 501 and the inner wall of the insert sleeve 5, and a slot 401 matching with the insert sleeve 5 is provided on the surface of the connecting plate 4, and a slide groove 402 and a slot 403 connected with the slot 401 are also provided on the surface of the connecting plate 4; when performing traction force detection, the block 501 is first pressed into the inside of the insert sleeve 5, and then the insert sleeve 5 is inserted into the slot 401, and the insert sleeve 5 is continuously rotated to move the block 501 into the slot 403, and then the third spring 502 will bounce the block 501 into the slot 403 to fix the cable 302 on the connecting plate 4, thereby facilitating the installation and disassembly of the cable 302, and then facilitating the disassembly and storage of the tension sensor 301.

[0052] like Figure 2 , Figure 3 , Figure 4 and Figure 6 , Fig.10 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the shaking assembly includes a U-shaped seat 9 arranged on the top of the detection platform 1, a screw rod 10 rotatably arranged on the side wall of the U-shaped seat 9, a movable seat 1001 symmetrically threaded on both sides of the screw rod 10 and slidably connected to the U-shaped seat 9, a movable column 11 movably arranged between the movable seat 1001 and the bottom of the mounting plate 2, and a transmission assembly arranged on the top of the detection platform 1, and the transmission assembly can drive the screw rod 10 to rotate back and forth when the traction rope 801 is pulled;

[0053] The transmission assembly includes a bracket 6 arranged at the bottom of the connecting plate 4 and slidably connected to the top of the detection platform 1, a tooth groove 601 arranged on the side wall of the bracket 6, a first rotating column 12 and a second rotating column 13 rotatably arranged on the top of the detection platform 1, a third rotating column 14 rotatably arranged on the top of the detection platform 1 and perpendicular to the second rotating column 13, a first complete gear 1202 and an incomplete gear 1201 arranged on the rod wall of the first rotating column 12, a second complete gear 1301 and an active bevel gear 1302 arranged on the rod wall of the second rotating column 13, a torsion spring 1303 sleeved on the rod wall of the second rotating column 13, a driven bevel gear 1401 arranged on the rod wall of the third rotating column 14, and a belt 1402 arranged between the third rotating column 14 and the screw 10 for transmission;

[0054] When the traction rope 801 pulls the connecting plate 4 and the bracket 6 to move, the bracket 6 will drive the first rotating column 12 provided with the first complete gear 1202 to rotate through the tooth groove 601, and the first rotating column 12 will drive the incomplete gear 1201 to rotate. When the incomplete gear 1201 rotates to the toothed side and contacts the second complete gear 1301, it will drive the second complete gear 1301 and the second rotating column 13 to rotate and make the torsion spring 1303 rotate. When the incomplete gear 1201 rotates to the toothless side and contacts the second complete gear 1301, the torsion spring 1303 will be released from the force and drive the second rotating column 13 to reverse and reset. The rotating column 13 will drive the third rotating column 14 provided with a driven bevel gear 1401 to rotate reciprocatingly through the active bevel gear 1302, and then drive the screw rod 10 to rotate reciprocatingly through the belt 1402, thereby driving the two movable seats 1001 on the screw rod 10 to move relative to each other, gradually approaching and moving away, and finally pushing the mounting plate 2 up and down through the movable column 11, so that the support seat 3 and the tension sensor 301 on the mounting plate 2 shake, which can simulate the traction force when the rubber-wheeled vehicle is moving due to vibration and the connecting end of the traction rope 801 and the tension sensor 301 is shaking, thereby improving the accuracy of the detection data.

[0055] like Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig.11 , Fig.14 and Fig.15 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the clamping assembly includes support cylinders 15 symmetrically arranged on both sides of the top of the testing platform 1, a sliding column 23 slidably arranged inside the support cylinder 15, a pressure block 2301 arranged at the bottom of the sliding column 23, a first spring 2302 arranged between the pressure block 2301 and the inner bottom wall of the support cylinder 15, an extrusion seat 16 arranged at the top of the sliding column 23, a support column 1501 arranged on the outer wall of the support cylinder 15, and a fixed seat 17 arranged at the top of the support column 1501 and matched with the extrusion seat 16, a pressure strip 1601 is provided at the bottom of the extrusion seat 16, a pressure groove 1701 matched with the pressure strip 1601 is opened at the top of the fixed seat 17, and a locking assembly is also provided between the extrusion seat 16 and the fixed seat 17;

[0056] When the traction rope 801 is unhooked from the rubber-wheeled vehicle or breaks due to excessive tension during the detection process, the tension of the traction rope 801 will disappear instantly. At this time, the first spring 2302 will drive the sliding column 23 to move downward, and make the extrusion seat 16 and the fixing seat 17 resist each other, and the traction rope 801 will be pressed into the pressing groove 1701 through the pressure strip 1601, so that the traction rope 801 that is instantly broken or detached can be fixed, preventing the traction rope 801 from instantly breaking and bouncing around to hit the workers and causing injuries. In addition, there is no need for equipment or personnel to observe the state of the traction rope being pulled to determine when the traction rope will break. As long as the traction rope breaks, it can be clamped and fixed immediately, and the clamping speed is fast. Compared with the prior art that requires personnel or equipment to monitor the traction rope to prevent the traction rope from breaking, the technical solution of the present application can save personnel and equipment costs.

[0057] Furthermore, the locking assembly includes a fixing column 18 arranged on both sides of the extrusion seat 16, a fixing cylinder 19 arranged on both sides of the fixing seat 17 and matched with the fixing column 18, a sliding sleeve 20 arranged on the side wall of the fixing cylinder 19 and connected with the fixing cylinder 19, a locking block 21 slidably arranged inside the sliding sleeve 20, and a second spring 2101 arranged between the locking block 21 and the inner wall of the sliding sleeve 20, and a locking groove 1801 matched with the locking block 21 is opened on the side wall of the fixing column 18, wherein a bolt 2201 is threadedly connected to the side wall of the sliding sleeve 20, a pull rope 22 is connected between the bolt 2201 and the locking block 21, a spring block 1901 is slidably connected to the inner wall of the fixing cylinder 19, and a fifth spring 1902 is connected between the spring block 1901 and the inner bottom wall of the fixing cylinder 19; when the extrusion seat 16 and the fixing cylinder 19 are locked, the fixing cylinder 19 is locked. After the fixed seat 17 is abutted, the fixing column 18 will be inserted into the fixing tube 19, and then the second spring 2101 will bounce the locking block 21 into the locking groove 1801 to lock the fixing column 18, thereby completely fixing the extrusion seat 16 and the fixing seat 17 after the abutment, and further improving the stability of clamping and fixing the broken traction rope 801. When the traction rope 801 needs to be loosened, the bolt 2201 on the sliding sleeve 20 can be screwed out, and the locking block 21 can be pulled back into the sliding sleeve 20 through the pull rope 22 to disengage from the locking groove 1801. At this time, the fixing column 18 is loosened, and the fifth spring 1902 will be released from the force to drive the spring block 1901 to bounce upward, thereby being able to push the extrusion seat 16 and the fixing seat 17 to quickly separate, making it easy to quickly remove the traction rope 801.

[0058] like Figure 2 , Figure 3 , Fig. 9 and Fig.12As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a protection component is provided on the top of the testing platform 1, and the protection component includes a support plate 24 arranged on the top of the testing platform 1, a fixed frame 2401 arranged on both sides of the top of the support plate 24, a slide 25 slidably arranged inside the fixed frame 2401, a fourth spring 2502 arranged between the slide 25 and the inner wall of the fixed frame 2401, and a first roller 2501 rotatably arranged at one end of the slide 25 away from the fixed frame 2401;

[0059] The protection assembly also includes a U-shaped plate 26 arranged on the side walls of both ends of the support plate 24, a second torsion spring shaft 27 rotatably arranged on the inner wall of the U-shaped plate 26, a rotating rod 2701 sleeved on the outside of the second torsion spring shaft 27, and two second rollers 28 symmetrically arranged on the rotating rod 2701, and the traction rope 801 extends outward through the two first rollers 2501 and the two second rollers 28;

[0060] When the rubber-wheeled vehicle drives the traction rope 801 to deviate, if it deviates to the left or right, the traction rope 801 will stick to the first roller 2501 and squeeze the first roller 2501. At this time, the first roller 2501 will slide toward the inside of the fixed frame 2401 through the slide seat 25 and squeeze the fourth spring 2502. The fourth spring 2502 can buffer the sliding first roller 2501. When the traction rope 801 deviates in the up and down directions, the traction rope 801 will stick to the second roller 28 and squeeze the second roller 28. At this time, the second torsion spring shaft 27 can make the compressed second roller 28 flip up and down, thereby buffering and blocking the deviated traction rope 801, preventing the contact part of the traction rope 801 and the tension sensor 301 from being worn due to excessive deviation angle, affecting the traction data detection.

[0061] The working principle of the present invention is as follows: when it is necessary to detect the traction force of the rubber-tyred vehicle, first connect the end of the traction rope 801 away from the detection platform 1 to the rubber-tyred vehicle through a hook, then start the rubber-tyred vehicle to move and pull the traction rope 801, the traction rope 801 is pulled out of the reel 8 and then pulls multiple tension sensors 301 through the connecting plate 4 and a plurality of tension cables 302, so that the larger traction force generated by the traction rope 801 can be divided into multiple smaller traction forces acting on each tension sensor 301 respectively, and the traction force of the rubber-tyred vehicle can be detected by the sum of the traction forces detected by multiple tension sensors 301, thereby preventing the sensor from being damaged due to excessive traction force on the tension sensor 301 when only one tension sensor 301 is used for detection. When the traction rope 801 pulls the connecting plate 4 and the bracket 6 to move, the bracket 6 will drive the screw rod 10 to rotate back and forth through the set transmission assembly, thereby driving the two movable seats 1001 on the screw rod 10 to move relative to each other, gradually approaching and moving away, and finally pushing the mounting plate 2 up and down through the movable column 11, so that the support seat 3 and the tension sensor 301 on the mounting plate 2 shake, which can simulate the traction force when the connecting end of the traction rope 801 and the tension sensor 301 shakes due to vibration when the rubber-wheeled vehicle moves, thereby improving the accuracy of the detection data. Moreover, when the traction rope 801 is unhooked from the rubber-wheeled vehicle or breaks due to excessive tension during the detection process, the tension of the traction rope 801 will disappear instantly. At this time, the first spring 2302 will drive the sliding column 23 to move downward, and make the extrusion seat 16 and the fixing seat 17 abut against each other, and the traction rope 801 will be pressed into the pressing groove 1701 through the pressure strip 1601, so that the traction rope 801 that is instantly broken or detached can be fixed, preventing the traction rope 801 from instantly breaking and bouncing around to hit the workers and causing injuries. If the rubber-wheeled vehicle drives the traction rope 801 to deviate, if it deviates to the left or right, the traction rope 801 will stick to the first roller 2501 and squeeze the first roller 2501. At this time, the first roller 2501 will slide toward the inside of the fixed frame 2401 through the slide seat 25 and squeeze the fourth spring 2502. The fourth spring 2502 can buffer the sliding first roller 2501. When the traction rope 801 deviates in the up and down directions, the traction rope 801 will stick to the second roller 28 and squeeze the second roller 28. At this time, the second torsion spring shaft 27 can make the compressed second roller 28 flip up and down, thereby buffering and blocking the deviated traction rope 801, preventing the contact part of the traction rope 801 and the tension sensor 301 from being worn due to excessive deviation angle, affecting the traction data detection.

[0062] The present invention also discloses a detection method of a maximum traction force detection device for a mining rubber-tyred vehicle, comprising the following steps:

[0063] S1: First, fix the traction rope 801 on the rubber-wheeled vehicle, then start the rubber-wheeled vehicle to move and pull the traction rope 801, the traction rope 801 will pull the multiple cables 302 through the connecting plate 4, and then pull the multiple tension sensors 301, the traction force generated by the rubber-wheeled vehicle is divided into multiple strands and respectively acts on the multiple tension sensors 301, and then the traction force of the rubber-wheeled vehicle is detected by the multiple tension sensors 301;

[0064] S2: When the rubber-tyred vehicle pulls the traction rope 801, the traction rope 801 will drive the connecting plate 4 and the bracket 6 to move. At this time, the transmission assembly can drive the screw rod 10 to rotate back and forth, and the screw rod 10 will push the mounting plate 2 up and down through the movable seat 1001 and the movable column 11, so that the support seat 3 and the tension sensor 301 on the mounting plate 2 shake up and down, thereby simulating the traction force of the traction rope 801 and the tension sensor 301 contacting end shaking due to vibration of the rubber-tyred vehicle during driving;

[0065] S3: When the traction rope 801 breaks due to shaking or excessive force, the tension of the traction rope 801 will disappear instantly. At this time, the first spring 2302 will drive the sliding column 23 to slide downward instantly, and the extrusion seat 16 will move down to abut against the fixing seat 17. The traction rope 801 is pressed into the pressing groove 1701 by the pressure strip 1601, and the extrusion seat 16 and the fixing seat 17 are fixed after abutting against each other by the locking assembly, so that the broken traction rope 801 can be clamped and fixed;

[0066] S4: If the rubber-wheeled vehicle deviates to the left or right during movement, the traction rope 801 will be driven to deviate to the left or right sides. The traction rope 801 will stick to the first roller 2501 and squeeze the first roller 2501 to slide to both sides. When the traction rope 801 deviates to the up and down directions, it will stick to the second roller 28 and squeeze the second roller 28 to rotate to the up and down directions, thereby providing buffer protection for the deviated traction rope 801.
