Description

Technical Field

[0001] The utility model relates to the technical field of open-pit mine operation equipment maintenance, in particular to a cable car crawler track rerailing device. Background Art

[0002] The electric shovel is one of the main mining equipment in tens of millions of tons open-pit mines. It has high productivity, high operating rate and low operating cost. The electric shovel operation uses high voltage electricity transmitted by cable as the real-time power source. The reliability of the electric shovel power supply directly affects the efficiency of the electric shovel mining work. The voltage of the high-voltage line transmitted to the vicinity of the mine is 20KV, which is converted to 6KV through the cable car transformer and then supplies power to the electric shovel in real time.

[0003] When the electric shovel is working on site or transferring, it will move forward, backward, left or right as the excavation work progresses, and the cable car that supplies power to it also needs to move with the car. At present, most of the commonly used cable cars on the market are crawler-type, which is convenient for dealing with the complex terrain of the construction site. During the long-term use of the crawler, the wear of the crawler plate pin holes and crawler pins causes the entire crawler to lengthen and loosen, resulting in frequent derailment, with an average of 3-5 derailments per month. The previous treatment method was to loosen the top crawler cylinder first, then move the cable car back and forth to wait for the supporting wheels to move up, and then tighten the crawler. Each treatment time is at least 2-3 hours. In addition, during this process, the supporting wheels will derail and the edges of the supporting wheels will come into hard contact with the crawler pin shaft, causing the pin shaft to wear. Multiple wear will cause the pin shaft to be scrapped. This process consumes a lot of manpower, time and energy, seriously affecting the working efficiency of the machinery, and reducing the actual operation rate of the electric shovel during the stop period. For this reason, we need a cable car crawler track rerailing device to quickly solve the crawler derailment problem. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] The utility model provides a cable car track rerailing device, which is used for rerailing the derailed supporting roller 7 of the cable car. The cable car track rerailing device comprises a support plate 1, a support frame 2 and a rerailing ramp 3, the support frame 2 is fixed to the lower side of the support plate 1, the two ends of the rerailing ramp 3 are respectively a connecting end and a guiding end, the connecting end is connected to one end of the support plate 1, and the guiding end is lower than the connecting end, so that the rerailing ramp 3 is inclined; wherein, the support plate 1 is supported by a connecting plate 4 of the track of the cable car, the support frame 2 cooperates with a pin stopper of the track to limit the position of the cable car track rerailing device, the guiding end is placed in a groove of the connecting plate 4, and the support plate 1 and the rerailing ramp 3 guide the derailed supporting roller 7.

[0028] When in use, the cable car track re-tracking device is placed in front of the derailed supporting roller in the connecting plate. After the supporting roller is derailed, one side of the wheel rim is on the inner side of the connecting plate 4 of the track, and the other side of the wheel rim is on the outer side of the connecting plate 4 of the track. At this time, the inner wheel rim can move along the re-tracking ramp 3 to the support plate 1, and return to the correct track after passing the support plate 1. This method changes the traditional cable car re-tracking method in open-pit coal mines. Without loosening or tightening the track, jacks, etc., a gentle ramp is built to allow the derailed supporting roller to return to the track through the gentle slope by relying on its own walking driving force. The re-tracking operation is simple and can be completed by one person.

[0029] The specific operating steps for using the cable car track rerailing device are described as follows.

[0030] Step 1: Place the cable car track rerailing device at the roller that needs to be rerailed, and align the rerailing ramp with the roller that needs to be rerailed.

[0031] Step 2: Fix the support frame to the pin joint of the track connecting plate, and lock the connection between the support plate and the connecting plate to prevent sliding forward and backward.

[0032] Step 3: Place the support plate steadily on the track rail (that is, on the vertical plate of the connecting plate).

[0033] Step 4: Use the remote control to operate the cable car to move forward or backward, so that the derailed supporting wheels can move up to the support plate along the re-railing ramp.

[0034] Step 5: The supporting wheels stand on the support plate and move sideways and forward to return to the original track.

[0035] This solution can ensure that when the cable car derails, the cable car can be quickly rerailed using the rerailing device, thereby improving efficiency.

[0036] Among them, the connecting plate 4 includes a bottom plate and two vertical plates fixed on the bottom plate, the supporting plate 1 is supported by the two vertical plates, and the guiding end is located in the groove between the two vertical plates. The rerail ramp 3 is plate-shaped, and there is a gap between the rerail ramp 3 and the vertical plates.

[0037] The gap between the rerail ramp 3 and the vertical plate is 5 to 10 mm.

[0038] The support plate 1 is in the shape of a rectangular plate, and the thickness of the support plate 1 is 10 to 20 mm.

[0039] In the length direction of the connecting plate 4 , both ends of the supporting plate 1 have slopes 8 .

[0040] The support frame 2 is plate-shaped, and the thickness of the support frame 2 is 10 to 20 mm.

[0041] Optionally, the support frame 2 is plate-shaped; the length direction of the support frame 2 is parallel to the length direction of the groove, or the length direction of the support frame 2 is perpendicular to the length direction of the groove.

[0042] Optionally, there are two support frames 2, and the two support frames 2 are arranged at an interval.

[0043] Optionally, there are two re-tracking ramps 3 , which are respectively located on two opposite sides of the support plate 1 .

[0044] Optionally, the cable car crawler track rerailing device is made of iron, and the support frame 2 and the rerailing ramp 3 are both welded to the support plate 1 .

[0045] In order to better understand the purpose, function and specific design scheme of the utility model, the cable car crawler track rerailing device of the utility model is further described in detail below with reference to the accompanying drawings.

[0046] First embodiment:

[0047] like Figure 1-3 As shown, in the cable car crawler track rerailing device provided by the utility model, the width of the support plate 1 is consistent with the width of the outer edge of the connecting plate 4, a support frame 2 is fixedly connected below the support plate 1, and a rerailing ramp 3 is fixedly connected to the support plate 1 along the crawler direction, the support frame 2 can contact and connect with the first crawler pin 5, the height of the support frame 2 is consistent with the height of the connecting plate 4, the width of the rerailing ramp 3 is smaller than the width between the connecting plates 4, and the bottom end height is consistent with the bottom end of the support frame 2;

[0048] The support plate 1 is preferably an iron plate with a thickness of about 10mm-20mm. Because the overall mass of the cable car is about 10-20 tons and is relatively heavy, when the edge of the supporting wheel 7 walks on the support plate 1, the contact surface is relatively small and the pressure is relatively large. If the thickness of the support plate 1 is not enough, it is easy to be deformed by compression; the width of the support plate 1 is consistent with the width of the outer edge of the connecting plate 4, so that the supporting wheel 7 that has not derailed can also walk normally on the support plate 1; when the supporting wheel 7 moves forward and contacts the rerailing ramp 3, due to the deadweight of the cable car, a force is applied to the rerailing ramp 3, causing the rerailing device to move, thereby causing the support frame 2 to contact the first track pin 5, which plays a role of limiting and can prevent the rerailing device from When the height of the support frame 2 is consistent with the height of the connecting plate 4, the lower bottom surface of the support plate 1 is in contact with the upper surface of the connecting plate 4. When the supporting wheel 7 walks on the support plate 1, the upper surface of the connecting plate 4 and the support frame 2 will play a supporting role; the distance between the two vertical plates of the connecting plate 4 is 80mm, the width of the rerail ramp 3 is smaller than the width between the connecting plates 4, the width of the rerail ramp 3 is controlled at 60mm-70mm, and the edge of the rerail ramp 3 is 5mm-10mm away from the connecting plate. The annular rim on the supporting wheel 7 is about 20mm. Therefore, the supporting wheel 7 will not fall into the gap next to it when walking on the rerail ramp 3.

[0049] When in use, after the supporting roller 7 and the crawler track are derailed, there are wheel flanges on both sides of the derailed supporting roller 7, and the wheel flanges on both sides will rub against the outer side of the connecting plate 4 on one side and the inner side of the connecting plate 4 on the other side, and exert an opposite force on the connecting plate 4, resulting in partial deformation of the crawler track. The rerailing device is placed in front of the running of the derailed supporting roller 7, and the rerailing ramp 3 faces the direction of the derailed supporting roller 7. The supporting roller 7 moves along the rerailing ramp 3 to the support plate 1, and the supporting roller 7 returns to the correct track after passing through the rerailing device. The partially deformed crawler track will automatically return to its original position because the opposite torque disappears, completing the rerailing action.

[0050] The support frame 2 is preferably made of iron and is one in number. Its direction is on the same central axis as the rerailing ramp 3. Because the cable car is too heavy and its thickness is 10mm-20mm, when in use, one end of the support frame 2 away from the rerailing ramp 3 abuts against the first track pin 5, and the supporting wheel 7 can prevent the rerailing device from moving when rolling on the rerailing ramp 3, thereby playing a role of limiting.

[0051] The rerailing ramp 3 is preferably one, and the rerailing device is placed in front of the derailing supporting wheel 7. The rerailing ramp 3 faces the direction of the derailing wheel. At this time, the rerailing ramp 3 is located above the second track pin 6 and is in contact with it. When the supporting wheel 7 runs on the rerailing ramp 3, the second track pin 6 can play a supporting role to prevent the rerailing ramp 3 from being bent.

[0052] There are slopes 8 at both ends of the support plate 1 to facilitate the supporting wheels 7 to drive down the support plate 1. If it is a right angle, under the gravity of the supporting wheels 7, the right angle side will be deformed and indented due to long-term stress.

[0053] Second embodiment:

[0054] like Figure 4 As shown, there is only one support frame 2, but the direction of the support frame 2 is perpendicular to the direction of the retracking ramp 3. The support frame 2 is located at one end of the support plate 1, away from the retracking ramp 3. When in use, the outer side of the support frame 2 is in contact with the first track pin 5, which plays a role of limiting. The two side surfaces of the support frame 2 are in contact with the inner side of the connecting plate 4, which can prevent the retracking device from moving left and right.

[0055] Third embodiment:

[0056] like Figure 5 As shown, there are two symmetrical rerailing ramps 3, which are respectively located above the first track pin 5 and the second track pin 6 and are in contact with each other. There is only one support frame 2, which is on the same central axis as the rerailing ramp 3. When multiple supporting wheels 7 are derailed, the rerailing device is placed between the two derailing wheels, and the cable car is moved forward and backward. Without manually moving the rerailing device, the two derailing wheels can be rerailed at the same time. This embodiment can be used in combination with some structures of the first embodiment and the second embodiment.

[0057] Fourth embodiment:

[0058] like Figure 6 As shown, in combination with the second and third embodiments, there are two support frames 2, the direction of the support frames 2 is perpendicular to the direction of the retracking ramp 3, there are two symmetrical retracking ramps 3, and the retracking ramps 3 are respectively located above the first track pin 5 and the second track pin 6 and are in contact with each other. When in use, after the retracking device is placed in a suitable position, the outer sides of the two support frames 2 are in contact with the first track pin 5 and the second track pin 6, respectively.

[0059] The cable car often derails during actual use, with an average of 3-5 derailments per month. At present, the cable car is maintained by the manufacturer, and there is no maintenance personnel stationed in the mine. The maintenance force is weak and the waiting time for repair is long, which causes the day shift to affect about half of the shift, and the night shift to affect the time even longer. At the same time, the traditional treatment method is to loosen the oil cylinder of the top track first, then move the supporting wheel 7 up, and then tighten the track. Each treatment time is at least 2-3 hours. The maintenance time is too long, and the shovel stop greatly reduces the actual operation rate of the electric shovel.

[0060] After the construction site adopts this rerailing device, it is easy to operate. The track can be rerailed within 10-20 minutes after derailment, saving 4-6 hours per time, greatly shortening the rerailing time of track derailment, saving 70% of maintenance time, and reducing the average monthly failure time of the cable car shovel by 12-30 hours; in terms of personnel, 1-2 people can complete the rerailing work. Based on an average of 3-5 derailments per month, the monthly stripping volume of the shovel increases by 30,000 to 60,000 cubic meters.
