According to one aspect of the utility model, the side-discharging skip dumping device for inclined shafts includes a skip chassis, a hopper arranged above the skip chassis and capable of dumping materials in a first direction, a slag storage system, and a trestle system and curved track, wherein, the slag collection system is located on the ground away from the wellhead of the inclined shaft, and is used to hoard waste rock unloaded from the skip; the trestle system includes a track with a predetermined slope and a track running platform, and the track The operating platform includes a bracket and sleepers laid on the bracket, the skip chassis can walk along the track, the trestle system extends from the wellhead of the inclined shaft to above the slag collection system; the curved rail is fixed on the slag collection system On the end of the sleeper above the system away from the first direction, the side of the curved rail close to the skip chassis is fixed with a limiting part, and the limiting part can prevent the skip caused by the side discharge of the hopper. The roll of the bucket chassis. the

When the skip is unloading gangue, the chassis of the skip will tend to tilt, and the center of gravity of the skip is biased towards the first direction. The rail is transmitted to the sleeper, that is, the end of the sleeper fixed with the curved rail is under downward pressure. According to the principle of leverage, the other end of the sleeper (that is, the end close to the first direction) will have a tendency to warp upwards. At this time, the skip chassis The part close to the other end of the sleeper is subjected to an upward force, which offsets the force generated by the deviation of the center of gravity of a part of the skip to the first direction, thereby reducing the possibility of the skip turning over and derailing. the

If the way of setting the limit part on the curved rail is adopted alone, and the curved rail and the crossties are installed independently, although the possibility of the skip rollover can be reduced to a certain extent by pressing the bottom of the skip through the limit part, but the long-term Using this mode of forcibly suppressing the skip is prone to loosening and damage, and problems such as short service life. However, in the gangue turning device of this exemplary embodiment, curved rails with limiting parts are installed on the sleepers, and the skip is prevented from turning over through the mutual transmission of force, which is more conducive to the stability of the whole gangue turning device. the

In a preferred exemplary embodiment of the side-discharging skip dumping device for inclined shafts of the present invention, the skip chassis is fixedly connected with the rollers running on the track, and the limiting part is located on the rollers. Upper anti-overturn ribs. In operation, when the skip moves to the overturning position, the anti-overturning rib is just above the rollers in the sideways discharge direction (that is, the first direction) of the hopper far away from the skip, so as to limit the The side tilt of the roller caused by the dumping of the material avoids the side tilt of the skip chassis caused by the side dump of the skip. However, the utility model is not limited thereto, and other parts of the skip chassis or other parts fixedly connected with the skip chassis can also be limited by the anti-overturning ribs, so as to prevent the skip from falling due to the side discharge of the skip. The side tilting of chassis, to reach the effect that prevents the side unloading type skip of the present utility model from overturning. Due to the large volume of the roller, it is not easy to get stuck when turning over the gangue. Therefore, it is preferable to arrange an anti-overturning rib above the roller. the

As for the anti-vehicle component, the front end of the skip chassis has a protruding part (for example, for hanging a traction rope), and the anti-vehicle component has a structure capable of embedding the protruding part. Its working principle is: when the skip moves to the turning position, the protruding part of the skip chassis just embeds the car-stopping member to prevent the forward and upward movement of the skip. It can be seen that, in addition to preventing the skip from advancing, the vehicle blocking member can also suppress the skip on the track when the skip tends to roll over. Further, the vehicle blocking member is a detachable structure. When the skip is stuck together with the vehicle-blocking device due to the movement tendency, the vehicle-blocking member can be removed. the

In another preferred exemplary embodiment of the side-discharging skip dumping device for inclined shafts of the present invention, the trestle is a steel structure, since the entire dumping device is basically made of metal and is located in an open area. Such as encountering the thunderstorm season will bring a very large safety hazard. The installation of the lightning rod for the gangue turning device of this embodiment has a considerable degree of particularity, because the entire structure can conduct electricity, and the lightning rod must be strictly prohibited from contacting the structure during the grounding process. In this embodiment, a lightning protection system suitable for steel trestle bridges is provided. The lightning protection system includes a lightning receptor made of metal material, a bracket, a lead wire and a grounding body. Wherein, the shape of the lightning receptor is a needle with a sharp head; the bracket is used to fix the lightning receptor on the trestle system, and there is no conduction between the bracket and the lightning receptor , and the air-termination device is not in direct contact with the trestle; the outer surface of the lead wire is covered with insulating material, one end of the lead wire is connected to the air-termination device, and the other end is connected to the grounding body buried underground. the

In another preferred exemplary embodiment of the side-discharging skip dumping device for inclined shafts of the present invention, the bracket is composed of three layers of pallets that overlap up and down and are fixed together, wherein the upper bracket The board is used to weld and fix the air-terminating device. The supporting plate in the middle layer is made of insulating material, and the supporting plate in the lower layer is fixedly connected with the trestle; connect. the

In another preferred exemplary embodiment of the utility model of the side-discharging skip turning gangue device for inclined shafts, when the skip enters the curved track to turn gangue, in order to prevent the falling gangue from colliding and smashing the support, the The width of the support below the curved rail is narrower than that of other parts. the

As shown in Fig. 1A to Fig. 1D, a certain steel factory carries out inclined shaft construction, and the inclined shaft hoisting system includes a skip 100, an I-type derrick 200, a winch 300 and a gangue turning device. The skip 100 is transported from the wellhead of the inclined shaft to the gangue turning device. The gangue turning device in this embodiment includes a slag collection system, a trestle system, curved rails, a vehicle blocking structure, and a lightning protection system. the

Wherein, the slag collection system 1 is located on the ground away from the wellhead of the inclined shaft. Because the slag transported out of the well relies on the loader to cooperate with Steyr trucks for secondary transfer, in order to ensure the efficiency of the secondary transportation, the effective volume of slag at the turning point should be greater than the volume of slag transported by two rounds of guns, about 80m ³ . Therefore, the slag storage system at the dumping site in this embodiment is composed of two 4.5m high rubble concrete piers, and the storage and transfer point for slag is reserved between the two piers. As shown in FIG. 1B , the circle area formed by the dotted line is the slag area. This not only satisfies the requirements for slag collection, but also ensures that the slag does not splash around when it is turned down, and when the slag falls, it hits the concrete pier instead of the steel support, which is safer than the pure steel truss-type gangue turning platform.

In order to ensure that the angle of the ropes inside and outside the hoisting well is consistent, the skip 100 adopts a trestle system to turn the gangue after leaving the well. The trestle system includes supports 2 , rails 3 and sleepers 4 . The gangue trestle requires higher rigidity and stability. Therefore, the trestle in this embodiment is a steel structure, wherein the steel support 2 includes a plurality of steel structure columns, and a steel structure erected on the column along the running direction of the skip bucket 100. The longitudinal girder and the reinforcement provided between the pillars are composed. The steel support 2 is fixedly installed on the reinforced concrete foundation buried under the ground. The crossties 4 are laid on the top of the steel support 2 along the running direction perpendicular to the skip bucket 100 . The rail 3 is laid on the sleepers 4, and there is a certain angle between the rail 3 and the ground. the

As shown in Fig. 2A and Fig. 2B, the curved rail 5 is fixed on an end near the outer side of the rail 3 of the sleeper 4 located above the slag system 1 . The curved rail 5 of the present embodiment is a wide 200mm made of channel steel, a length of 3900mm, and a truss-shaped member of a height of 1100mm. For ease of installation, the sleepers 4 on the curved rail side are longer than the sleepers 4 on the slag unloading side. Since the curved rail 5 cannot be directly welded on the sleeper 4, in order to fix the curved rail 5 on the sleeper 4, a welding surface can be formed on the sleeper, for example, use two sections of channel steel to clamp the sleeper 4 relatively, and cover the groove of the sleeper 5 The lower part of the steel is welded on the longitudinal beam of the steel structure, and the upper part of the channel steel is welded together with the curved rail 5. The curved rail 5 adopted in the present embodiment requires that the bottom surface and the track surface be at the same height during installation. Therefore, joist 6 as shown in FIG. the

As shown in FIG. 3 , the skip 100 has a roller 110 acting on the rail 3 , and the skip chassis 120 of the skip 100 is fixedly connected to the roller 110 . The side of the curved rail 5 close to the skip chassis has an anti-overturning rib 7, and when the skip 100 moves to the overturning position on the curved rail 5, the anti-overturning rib 7 is just located on the side away from the hopper 130 of the skip 100 Above the roller 110 in the direction of dumping material (that is, the roller 110 on the right side in FIG. The side tilting of the skip chassis 120 caused by the side dumping. That is to say, when the skip 100 turns over, the anti-overturning ribs 7 press the rollers 110, and transmit the received force to the sleepers 4, and prevent overturning and rollover through the force transmission. the

The rail gauge of the present embodiment is 900mm. In order to ensure that there is enough space for the maintenance channel and the stability of the trestle when the skip is running, the width of the steel support is set to 1500mm. When the skip enters the curved rail 5 and turns over, To prevent the falling gangue from colliding and smashing the bracket 2, the width of the bracket located under the curved rail is designed to be 1000 mm, and a beam 8 (for example, I32a I-beam) is arranged along the running direction of the skip bucket 100 at the position where the width changes , in order to achieve the purpose of smooth transition. the

In the prior art, a contact power-off device (or an electronic limiter) is generally installed on the top of the curved rail. When the skip 100 moves to the turning position on the curved rail 5, the winch worker can monitor and record it via video. Perform a power-off operation. However, the electronic limiter may fail or the skip inertia is too large to cause overwinding. In order to enhance the safety, in addition to the electronic safety measures, the present embodiment adds a mechanical anti-vehicle component. The anti-vehicle component is arranged between two sleepers in front of the track section where the curved rail is located. The front end of the skip chassis has a protrusion for hanging a traction rope. The anti-vehicle component has a shape that matches the section of the protrusion, so The protruding part can be embedded in the vehicle blocking member. As shown in Figures 5A and 5B, the anti-vehicle member is a frame with an upper opening. The base 10 , the clamping strips 11 (for example, I-shaped steel) on both sides, and the movable pin, wherein the clamping strips 11 are detachably inserted into the base 10 . Specifically, there is a pin hole on the end of the clip bar 11 inserted into the base 10, and there is a mounting hole on the base 10, and the movable pin 12 can pass through the mounting hole on the base 10 and be installed in the pin hole. , so that the base 10 and the clip bar 11 are fixedly connected together. When the skip 100 is stuck together because of the movement tendency and the vehicle blocking member, both can be loosened by pulling out the movable latch 12 . It should be noted that the upper part of the car-blocking member in this embodiment has an opening, mainly for the purpose of reducing the weight of the clip strip 11 to facilitate manual disassembly without affecting the car-stopping effect. Therefore, the traffic blocking member can also be a closed structure without an opening. the

The lightning protection system is composed of a lightning receptor 13, an upper supporting plate 14, an intermediate supporting plate 15, a lower supporting plate 16, a lead wire 17, and an unshown grounding body. Wherein, the lightning receptor 13 is made of galvanized steel pipe, and its top is sharpened. The upper pallet 14 , the middle pallet 15 and the lower pallet 16 overlapping and fixed together form a bracket for welding and fixing the air receptor 13 on the trestle. The upper supporting plate 14 is made of steel plate, which is used for welding and fixing the lightning receptor; the middle supporting plate 15 is made of insulating wood board, which plays the role of isolation; the lower supporting plate 16 is made of steel plate and channel steel for supporting, and the lower supporting plate Plates are welded on the trestle. It should be noted that neither the steel plate nor the channel steel of the lower supporting plate 16 shall have direct contact with the lightning receptor 13 and the lead wire 17 . The bolts fixing the three-layer pallet must first be put through the casing and then passed through the pallet for fixing. The lightning receptor 13 is connected to the grounding body through the lead wire 17 after passing through the three-layer pallet. Lead wire 13 is made by the round steel that brushes antirust paint, and lead wire outer surface wraps PVC insulating pipe. The grounding body is composed of sporadic flat steel, angle steel, or steel bars buried in the ground. the

In another embodiment of the present utility model, the structure of the gangue turning device is basically the same as that of the above-mentioned first embodiment, the difference lies in the limiting part. In this embodiment, a groove is provided on the side of the curved rail close to the skip chassis, and a protrusion (for example, a retaining wheel) entering the groove is fixedly arranged on the skip chassis. At the same time, the protrusion enters the groove to limit the side tilt of the chassis caused by the side dump of the skip. Theoretically, this kind of limiting setting can also realize the suppression of the skip chassis, but the specific implementation effect is not as good as the limiting effect of setting the anti-overturning ribs in the first embodiment above. This is because, in actual operation, the skip is not allowed to have too much displacement of the chassis, and the installation accuracy requirements for the facilities for suppressing the skip are very high, and it is relatively difficult to slot and install matching protrusions on the chassis. It may be difficult to implement, and the retaining wheel is easy to get stuck in the groove, and it is very difficult to release. the

To sum up, the gangue turning device of the present utility model arranges curved rails with limiting parts on the sleepers, and when the skip unloads gangue, the possibility of side turning and overturning of the skip is reduced through the transmission of force; The advanced mechanical car stop mechanism further ensures the stability of the entire gangue turning device; the lightning protection system eliminates potential safety hazards; the trestle structure is made of steel structure, which is faster in construction, easier in maintenance and easier to recycle than traditional masonry structures. It can be seen that the gangue turning device of the present utility model can produce a device with good anti-overturning effect by using a small amount of profiles, and can be used in any site and inclined shaft construction of any specification, and has high safety, stability and convenience. There is a substantial improvement. the

Although the utility model has been described above in conjunction with the exemplary embodiments, it should be clear to those skilled in the art that various modifications can be made to the exemplary embodiments of the utility model without departing from the spirit and scope defined in the claims. modify and change. the
