Technical Field
[0001] This utility model relates to the field of open-pit mining machine technology, and in particular to a plow-type alignment device and a mining machine. Background Technology
[0002] In existing technology, mining machines typically mine coal on one side, that is, they cut the coal face and transport the cut coal away. However, because the coal face is hard, the mining side usually experiences great resistance. Furthermore, during the mining machine's forward movement, this resistance causes the overall movement direction of the mining machine to deviate, which results in the cut coal face being tilted, thus preventing the mining machine from moving normally.
[0003] Therefore, how to prevent the mining machine from running off track due to the lateral force of coal cutting during coal mining, thereby ensuring that the coal face is cut straight and thus ensuring the normal coal mining movement of the double-drum open-pit mining machine, is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0004] The purpose of this utility model is to provide a plow-type alignment device that can prevent the track of a mining machine from deviating due to the lateral force of coal cutting during coal mining, thereby ensuring that the coal face is cut straight and thus ensuring the normal coal mining movement of a double-drum open-pit mining machine; another purpose of this utility model is to provide a mining machine including the above-mentioned plow-type alignment device.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The insert plate is movably connected to the tailstock body. The insert plate can extend towards the ground to be in the working state and retract towards the mining machine to be in the storage state. When the insert plate is in the working state, the insert plate is in contact with the ground to prevent the mining machine from deviating from the direction of movement. When the insert plate is in the storage state, the insert plate is spaced apart from the ground.
[0009] Preferably, a lifting cylinder is installed inside the tailstock body, and the lifting cylinder is connected to a plug plate to provide power for its movement.
[0010] Preferably, the tailstock body has guide grooves on both sides in the first direction, and a lifting cylinder is installed in each guide groove. The insert plate is provided with guide protrusions that cooperate with the guide grooves to provide guidance for the movement of the insert plate.

[0012] Preferably, the end of the insert plate away from the tailstock includes: a wedge-shaped breaking edge and an insertion edge, with the breaking edge facing the same direction as the moving direction of the mining machine.
[0013] Preferably, the insertion edge gradually tapers in thickness in the direction away from the tailstock body to facilitate insertion of the insertion plate into the ground.
[0014] Preferably, the insertion edge is set at an angle relative to the ground.
[0015] This utility model also provides a mining machine, including the plow-type alignment device described above.
[0016] Preferably, the plow-type alignment device is connected to the mining machine via a pin assembly.

The pin assembly includes two parallel pins, which pass through the lug and the lug groove to install the plow-type alignment device.
[0019] Compared with the above-mentioned background technology, the present invention provides a plow-type deflection device, including: a tail frame body and an insert plate; the tail frame body is used to be installed on the non-coal mining side of the mining machine opposite to the coal mining side; the insert plate is movably connected to the tail frame body, and the insert plate can extend towards the ground to be in a working state and retract towards the mining machine to be in a stored state. When the insert plate is in the working state, the insert plate is in contact with the ground to prevent the mining machine from deviating from the direction of movement. When the insert plate is in the stored state, the insert plate is spaced apart from the ground.
[0020] Specifically, the plow-type deflection device provided in this application is installed on the non-coal mining side of the mining machine and can function when the mining machine is started. The tailstock body is vertically installed on the lower side of the mining machine, and the insert plate is movably connected to the tailstock body. Its movement direction is either extending towards the ground or retracting away from the ground. The insert plate has two states: one is the working state, in which the insert plate is inserted into the ground, and the force between the part inserted into the ground and the ground counteracts the lateral force on the mining machine on the coal mining side, thereby ensuring that the mining machine does not deviate from its original movement trajectory during movement; the other state of the insert plate is the retracted state, in which the insert plate is detached from the ground. This state is suitable for the mining machine to move without load, thus ensuring the movement speed of the mining machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.
[0032] The purpose of this invention is to provide a plow-type deflection device that can prevent the track from deviating due to the lateral force of coal cutting during mining, thereby ensuring that the coal face is cut straight and thus guaranteeing the normal coal mining movement of the double-drum open-pit mining machine.
[0033] To achieve the above objectives, the present invention provides the following technical solution:
[0034] Please see Figure 1 and Figure 2 This embodiment provides a plow-type deflection device 02, including: a tail frame body 100 and an insert plate 200; the tail frame body 100 is used to be installed on the non-coal mining side of the mining machine 01 opposite to the coal mining side; the insert plate 200 is movably connected to the tail frame body 100, and the insert plate 200 can extend towards the ground to be in a working state and retract towards the mining machine 01 to be in a stored state. When the insert plate 200 is in the working state, the insert plate 200 is in contact with the ground to prevent the mining machine 01 from deviating from the moving direction. When the insert plate 200 is in the stored state, the insert plate 200 is spaced apart from the ground.
[0035] The tailstock body 100 is a shell structure that can be fixedly installed on the mining machine 01, specifically on the lower part of the non-coal mining side opposite to the coal mining side. A movable insert plate 200 is installed inside the tailstock body 100. In this embodiment, the preferred direction of movement of the insert plate 200 is vertical; that is, the insert plate 200 can extend out of the tailstock body 100 or retract into the tailstock body 100 in a vertical direction. In this embodiment, the insert plate 200 has two states relative to the tailstock body 100: a working state and a retracted state. When in operation, the insert plate 200 extends out of the tailstock body 100 and inserts into the ground. As the mining machine 01 moves, it will drive the tailstock body 100 and the insert plate 200 to move. Since the insert plate 200 is inserted into the ground, there will be a certain force between it and the ground. This force can effectively prevent the mining machine 01 from deviating from its original direction of movement. When the mining machine 01 moves without load, the insert plate 200 can be retracted to detach it from the ground, thus preventing the insert plate 200 from affecting the movement speed of the mining machine 01.
[0036] In this embodiment, the insert plate 200 is a plate-shaped structure. When it is inserted into the ground, its location plane is parallel to the moving direction of the mining machine 01. It can be understood that when the insert plate 200 is vertically inserted into the ground, the soil layers on both sides of the insert plate 200 will firmly squeeze the insert plate 200, preventing it from moving in a direction perpendicular to its plate surface. In this way, the force exerted by the soil on the insert plate 200 can just offset the lateral force perpendicular to the insert plate 200 generated by the mining machine 01 due to coal cutting on the coal mining side. This allows the mining machine 01 to move in a straight line along a predetermined trajectory until the coal cutting is completed, at which point the insert plate 200 is retracted and pulled out of the ground.
[0037] In other words, the plow-type deflection device 02 provided in this application is installed on the non-coal mining side of the mining machine 01, and it can function when the mining machine 01 is started. The tailstock body 100 is vertically installed on the lower side of the mining machine 01, and the insert plate 200 is movably connected to the tailstock body 100. Its movement direction is specifically to extend towards the ground or retract away from the ground. The insert plate 200 has two states: one is the working state, in which the insert plate 200 is inserted into the ground, and the force between the part inserted into the ground and the ground is used to counteract the lateral force on the mining machine 01 on the coal mining side, thereby ensuring that the mining machine 01 does not deviate from its original movement trajectory during movement; the other state of the insert plate 200 is the retracted state, in which the insert plate 200 is detached from the ground. This state is suitable for the mining machine 01 to move without load, thus ensuring the movement speed of the mining machine 01.
[0038] Preferably, the tailstock body 100 is equipped with a lifting cylinder 110, which is connected to the insert plate 200 to provide it with the power to move.
[0039] Understandably, in order to achieve automatic lifting and lowering of the insert plate 200, a linear drive device, such as an electric push rod, a lifting cylinder 110, or a pneumatic cylinder, can be installed inside the tail frame body 100. In this embodiment, the lifting cylinder 110 is preferred. The cylinder body of the lifting cylinder 110 is connected to the tail frame body 100, and its piston rod is connected to the insert plate 200. This arrangement can realize the extension and retraction of the insert plate 200 in the plow-type adjustment device 02 to switch between different states at any time.
[0040] Preferably, the tailstock body 100 has guide grooves on both sides in the first direction, and a lifting cylinder 110 is installed in each guide groove. The insert plate 200 is provided with guide protrusions that cooperate with the guide grooves to provide guidance for the movement of the insert plate 200.
[0041] Understandably, in order to ensure the stability of the insert plate 200 during movement, two guide grooves can be set in the cavity inside the tail frame body 100. The guide grooves are located on both sides of the tail frame body 100, and a lifting cylinder 110 is installed inside each guide groove. The two lifting cylinders 110 can achieve synchronous operation. With this setting, by having the two lifting cylinders 110 act on the two ends of the insert plate 200 at the same time, it is easier and more convenient for the insert plate 200 to be inserted into the ground or pulled out, and the lifting process of the insert plate 200 is also more stable.
[0042] In addition, to make the movement of the insert plate 200 smoother, corresponding guide protrusions can be provided on both sides of the insert plate 200, that is, on the sides of the corresponding guide groove. The guide protrusions can slide in the guide groove, which can prevent the insert plate 200 from shaking during the lifting and lowering process. Rotatable guide wheels can also be provided on the guide protrusions. The guide wheels can roll in the guide groove. This arrangement can make the lifting and lowering of the insert plate 200 smoother.
[0043] Of course, it should be noted that a stop can be set at the bottom opening of the tailstock body 100. The stop can limit the guide protrusion to prevent the insert plate 200 from detaching from the tailstock body 100. Alternatively, a stop block can be set at a suitable position on the insert plate 200 to limit the movement range of the insert plate 200. However, the movement range of the insert plate 200 needs to ensure that it can be inserted downwards into the ground or pulled out to a certain height away from the ground to prevent it from affecting the movement of the mining machine 01.
[0044] Preferably, the tailstock body 100 is provided with an observation window 120 corresponding to the lifting cylinder 110 to facilitate maintenance of the lifting cylinder 110.
[0045] In this embodiment, an observation window 120 with a strip-shaped through hole structure is also provided at the position of the tail frame body 100 corresponding to the lifting cylinder 110. This setting allows the staff to see the specific situation of the lifting cylinder 110 very intuitively and conveniently, which is beneficial to the installation and maintenance of the lifting cylinder 110.
[0046] Preferably, the end of the insert plate 200 away from the tailstock body 100 includes: a ground-breaking edge 210 with a wedge-shaped structure and an insertion edge 220, wherein the orientation of the ground-breaking edge 210 is consistent with the moving direction of the mining machine 01.
[0047] In this embodiment, specifically as follows: Figure 2 As shown, the lower end of the insert plate 200 includes two connected edges, one of which is a wedge-shaped structure and faces the direction of movement of the mining machine 01, and the other is the insertion edge 220 at the bottom of the insert plate 200; wherein, the soil breaking edge 210 is an arc-shaped structure, which can more easily break the soil layer in front when the insert plate 200 is inserted into the ground, in conjunction with the wedge-shaped structure. This setting can minimize the increase in ground resistance caused by the plow-type adjustment device 02 when the mining machine 01 moves, thereby increasing the moving speed of the mining machine 01.
[0048] Preferably, the insertion edge 220 gradually decreases in thickness in the direction away from the tailstock body 100 to facilitate the insertion of the insertion plate 200 into the ground.
[0049] Understandably, in order to make it easier for the insert plate 200 to be inserted into the ground, its lowest insertion edge 220 can be set as a sharp structure like the cut of a blade, that is, the insertion edge 220 gradually narrows in thickness in the downward direction; with this setting, the lifting cylinder 110 can insert or pull the insert plate 200 into or out of the ground with very little force, thereby improving the response speed of the plow-type deflection device 02.
[0050] Preferably, the insertion edge 220 is set at an angle relative to the ground.
[0051] Furthermore, such as Figure 2 As shown, the insertion edge 220 is a straight line, but it is set at an angle relative to the ground, that is, it forms a small angle with the ground. The end closer to the breaking edge 210 is lower, and the end farther away from the breaking edge 210 is higher. As a result, its left end will form a relatively sharp corner, which is the connection point between the breaking edge 210 and the insertion edge 220. This sharp corner is located at the lowest end of the insertion plate 200. In other words, when the insertion plate 200 is inserted into the ground, this sharp corner will be inserted into the ground first. Then the insertion plate 200 will be inserted into the ground along the insertion edge 220. Due to the shape characteristics of the sharp corner, the insertion plate 200 can be inserted into the ground with little effort and quickly. Moreover, the sharp corner will be at the foremost point of the insertion plate 200 in the direction of movement, which can also reduce the resistance when the insertion plate 200 moves into the ground.
[0052] This utility model also provides a mining machine 01, which includes the plow-type alignment device 02 described above, and therefore has the beneficial effects of the plow-type alignment device 02.
[0053] Preferably, the plow-type alignment device 02 is connected to the mining machine 01 via a pin assembly 03.
[0054] Understandably, in order to facilitate the installation of the plow-type alignment device 02 on the mining machine 01, a lug is provided at a lower position on the non-coal mining side. At the same time, a corresponding lug groove is provided above the plow-type alignment device 02. During installation, the lug groove of the plow-type alignment device 02 can be fitted over the lug of the mining machine 01, and then the pin assembly 03 is inserted to connect the two. It should be noted that both the lug and the lug groove are provided with two parallel through holes, and the pin assembly 03 includes two pins. This arrangement can prevent the plow-type alignment device 02 from rotating relative to the mining machine 01, thereby ensuring the stability of its insert plate 200 when inserted into the ground, and thus ensuring that the mining machine 01 does not deviate from its movement path when cutting coal.
[0055] Preferably, it includes two sets of plow-type adjustment devices 02, and the two sets of plow-type adjustment devices 02 are symmetrically arranged at both ends of the non-coal mining side of the mining machine 01.
[0056] Furthermore, in this embodiment, the mining machine 01 is equipped with plow-type deflection devices 02 at both ends of its non-coal mining side, and the two are symmetrically arranged, that is, the soil-breaking edge 210 of the insert plate 200 of both faces away from the other plow-type deflection device 02. This arrangement can ensure that no matter which direction the mining machine 01 moves, the plow-type deflection device 02 can ensure that its movement path does not deviate.
[0057] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0059] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
