Abstract
Description
Technical Field
[0001] The utility model relates to a turnout for a cart pusher to pass through. Background Art
[0002] The pusher is an important auxiliary equipment in the field of mine transportation, which is used to push the vehicle on the mine track at the predetermined position of the mine track. The turnout is an important equipment that connects different mine tracks (different from the turnout, the object that is converted by the turnout is usually called a track, which is the mine track set around the turnout), for example, the mine car changes tracks on different tracks, and the turnout usually has cross tracks, which affects the setting of the pusher track.
[0003] In some implementations, the pusher track is arranged on one side of the mine track, and then a push claw extending transversely to the side where the mine track is located is used to push, for example, a mine car. However, this method cannot cross the turnout. In particular, since the pusher of this configuration does not provide a force application method along the pusher track, an additional and relatively large torque will be generated when pushing, for example, a mine car. The pusher track needs to be able to balance the torque, which creates a relatively large obstacle to the configuration of the pusher.
[0004] In some implementations, a ground groove is set on the inner side of the two track components of the mine track, and the cart track is set in the ground groove. Although this method can avoid the influence of the switch on the passage of the cart, the setting of the ground groove will affect the basic stability of the mine track, and when passing through the switch, the cart needs to be hidden in the ground groove. In the process of crossing the switch, the push for example, the mine cart will lose its propulsion. The mine cart needs to rely on inertia to pass the switch, and the continuity of the cart is greatly affected.
[0005] In view of this, integrating the pusher turnout into the mine track turnout is currently a more common implementation method, but the mine track turnout usually needs to meet the conversion between at least two sets of tracks. The turnout includes a turnout track and a slideway for turnout track conversion. The turnout occupies a relatively large space as a whole, and some areas in the mine are just not able to meet the requirements of turnout installation. Utility Model Content
[0006] The utility model aims to provide a turnout for a cart pusher to pass which has a compact structure and is relatively easy to control.
[0007] In an embodiment of the utility model, a turnout for a cart machine to pass through is provided, which is used for changing tracks between a first mine track and a second mine track that intersect at a predetermined position, and the turnout for the cart machine to pass through includes:
[0008] A pusher track is located between two track members of a first mine track and has a first gap at a predetermined switch, and a first track member of a corresponding second mine track has a second gap at a location where the first track member crosses the pusher track;

[0011] A driving device is used to drive the bridge track and the bridge rail to swing.
[0012] Optionally, the bridge track and the bridge rail are co-framed;
[0013] Accordingly, the first position is the same as the fourth position, and the second position is the same as the third position.
[0014] Optionally, the bridge track and the bridge rail are framed by a slat-shaped seat plate, which is hinged by a rotating shaft with an axis perpendicular to the rail surface;
[0015] The lower side of the seat plate is supported by an arc-shaped slideway.
[0016] Optionally, the bridging track is arranged in parallel with the bridging track.
[0017] Optionally, the driving device is a horizontally arranged linear motion mechanism or component.
[0018] Optionally, the component is a hydraulic cylinder or a pneumatic cylinder.
[0019] Optionally, the bridging track and the bridging rail are both single members;
[0020] The first notch exists in both track components of the trolley track, and the second notch exists in one track component of the second mine track; the length of the first notch of the first track component of the two track components is greater than the length of the first notch of the second track component, and the bridging track is used to bridge the first track component.
[0021] Optionally, the turning angle range shared by the bridge track and the bridge rail is the same as the angle between the first mine track and the second mine track at corresponding switches.
[0022] Optionally, the length of the first notch of the second track member is not greater than 40 cm.
[0023] Optionally, a guide plate is provided on the outer side of one end of the first notch of the second track member for introducing the cart machine.
[0024] According to the turnout for the pusher machine according to the embodiment of the utility model, firstly, the pusher machine track is located between the two track components of the first mine track, and no additional torque problem will be generated when pushing the cart. Furthermore, the second mine track has a second gap at the intersection of the first mine track and the second mine track, and the pusher machine track has a first gap at the turnout, and the second mine track has a second gap. A bridging track for bridging the second gap and a bridging track for bridging the first gap are provided, and both are installed in a hinged manner at one end. The state change of the bridging track and the bridging track depends on the change of their turning angle, which is relatively simple to implement. Since the distance between the pusher machine tracks is relatively small, in other words, the turning angle required to make way for the bridging track for the pusher machine track is not large. On the whole, the turnout structure for the pusher machine according to the embodiment of the utility model is relatively compact, and the swinging is relatively simple to implement, that is, the control is very simple.

[0029] In the embodiments of the present invention, concepts such as track and track are used mainly to distinguish different technical features, and do not mean that the corresponding term names impose specific restrictions on them.
[0030] exist Figure 1 and Figure 3 In the illustrated structure, a herringbone turnout structure is exemplified, but it should be known that the turnout for the cart pusher according to the embodiment of the utility model is also applicable to, for example, an X-type turnout structure.
[0031] For the convenience of description, Figure 1 and Figure 3 The two mine tracks 1 are respectively called the first mine track and the second mine track. For the pusher 7, the pusher track 2 used by it is relatively small in size and can be arranged between the two track components of the mine track 1.
[0032] In an embodiment of the utility model, a turnout for a pusher is provided, which is used for changing tracks between a first mine track and a second mine track that intersect at a predetermined position. Currently, turnouts generally use a translation method to change tracks, but in an embodiment of the utility model, a swing method is used to change tracks. Specifically, the turnout for a pusher includes a pusher track 2, a bridge track 5 and a bridge track 4, and a driving device for driving the bridge track 5 and the bridge track 4 to swing.
[0033] Since swinging is one of the most common forms of motion in the mechanical field, it is relatively easy to implement, and the purpose of swinging is, for example, to bridge the transition between two states of the track 5, and it only needs to control the angle of rotation. As for the relatively accurate and relatively simple stop control, a linear motion component, such as a hydraulic cylinder 6 or a pneumatic cylinder, can perform stop point control by itself.
[0034] The motion form output by the hydraulic cylinder 6 and other components is a typical linear motion. In the mechanical field, mechanisms that can output linear motion are more common, such as rack and pinion mechanisms, nut and screw mechanisms, and the like.
[0035] The pusher track 2 is arranged between two track components of the first mine track and is arranged in the center. Figure 1 and Figure 3 In the illustrated structure, the pusher track 2 has a first gap at a predetermined turnout. The first track component of the corresponding second mine track has a second gap at the location where it crosses the pusher track 2; the "first" in the first track component here is only used to distinguish different technical features, and does not represent an ordinal number.
[0036] The bridging track 5 is used to bridge the second gap at the first position and to leave the second gap at the second position. One end of the bridging track 5 is hingedly mounted on one end of the second gap.
[0037] Note: For a gap, corresponding to the default track or default track, the end of, for example, the second gap here refers to the end corresponding to the default track.
[0038] It should be known that making way for the second gap is to make way for the trolley track 2 , because as mentioned above, the second gap is provided for making way for the trolley track 2 .
[0039] Correspondingly, the bridge track 4 is used to bridge the first gap at the third position and to leave the first gap at the fourth position, and one end of the bridge track 4 is hinged to one end of the first gap. In this way, the bridge track 4 and the bridge track 5 are installed in a hinged manner, and the corresponding rotation axis 3 of the hinge is the rotation axis 3 perpendicular to the track surface. Under this condition, for example, the swing plane of the bridge track 5 is parallel to the track surface.
[0040] exist Figures 1 to 3In the illustrated structure, the bridge track 5 and the bridge track 4 are co-built, and Figure 2 In the illustrated structure, the bridge track 5 and the bridge rail 4 are framed by a seat plate 9, one end of which is mounted on a predetermined base, such as a base fixed on one side of the trolley track 2, through a rotating shaft 3.
[0041] The bridge track 5 and the bridge track 4 are built together, and the movement forms of the two must be the same. For the convenience of description, they are collectively referred to as the bridge assembly in the following text. The existence of the bridge assembly makes the aforementioned first position the same as the fourth position, and the second position the same as the third position. When the bridge assembly is in the first position, the bridge track 5 bridges the second gap, and the bridge track 4 makes way for the second gap; when the bridge assembly is in the second position, the bridge track 5 needs to make way for the second gap, and the bridge track 4 bridges the first gap.
[0042] As mentioned above, the bridge track 5 and the bridge rail 4 are jointly framed by a slat-shaped seat plate 9, which is simply hinged at one end and has relatively weak torsional shear resistance. Therefore, the lower side of the seat plate 9 is supported by an arc slide.
[0043] One or more curved slideways can be provided according to the load size.
[0044] exist Figure 1~Figure 3 As can be seen in the figure, the bridge track 5 and the bridge track 4 are arranged in parallel. Figure 1 and Figure 3 In the illustrated structure, the cart track 2 is roughly parallel to a mine track 1, and forms a predetermined angle with another mine track 1, and the angle is adapted to the relationship between the two mine tracks 1. The parallel arrangement of the bridging track 5 and the bridging track 4 can make the first position and the second position just meet the conversion bridge of the bridging assembly to the mine track 1 and the cart track 2.
[0045] From Figure 1~Figure 3 In the illustrated structure, the bridge track 5 and the bridge track 4 are both single components; Figure 1 It can be seen from the illustrated structure that when the bridging track 5 is a single track, it does not affect the passability of, for example, a mine car. However, when the bridging track 4 is a single track, even when the bridging track 4 is in a bridging state, part of the track components of a trolley track 2 are still in a default state. However, since the trolley 7 is generally longer and has a relatively large number of axles, it has a certain ability to cross the gap, especially under the condition that one side has complete support.
[0046] Correspondingly, both track components of the pusher track 2 have the first notch, and one track component of the second mine track has the second notch; the length of the first notch of the first track component of the two track components is greater than the length of the first notch of the second track component, and the bridge track 4 is used for bridging the first track component. From the above content, it can be seen that, for example, the bridge track 4 does not need to have a large swing angle (referred to as the rotation angle), and at this time, the following will occur Figure 1 In the state shown, the first track component on the left is much longer than the first track component on the right. Under the condition that the span of the bridging track 5 is met, the bridging track 4 parallel to the bridging track 5 is also relatively long, so that the relatively long bridging track 4 is used to bridge the first track component on the left, while the relatively short first track component on the right is partially omitted. However, because it is relatively short by default, the impact on the normal passability of the trolley 7 is relatively low.
[0047] Furthermore, in order to reduce the impact on the passability of the pusher 7, the missing portion of the first track component located on the right side should be as small as possible while satisfying the conditions for changing lanes, and is generally controlled to be less than 40 cm.
[0048] In addition, in order to prevent the pusher 7 from running off track, Figure 1 and Figure 3 It can be seen in the illustrated structure that a guide plate 8 is provided on the outer side of one end of the first notch of the track component of the trolley track 2 located on the right side for introducing the trolley 7 .
[0049] Finally, the turning angle range of the bridge track 5 and the bridge track 4 is the same as the angle between the first mine track and the second mine track at the corresponding switch. The overall structure is more compact, the driving range is relatively small, and the control is simpler.
