Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a turning device and coal mining equipment. Background Technology

[0002] Coal mine underground roadways have complex and diverse layouts, with numerous bends and branches. During tunneling, roadheaders need to adapt to different roadway shapes and directions to achieve efficient and continuous tunneling operations. When tunneling reaches a corner or when the tunneling direction needs to be changed, the roadheader and its associated transfer conveyor must be able to smoothly complete the turning maneuver to ensure the normal transportation of coal and the continuous progress of tunneling work. In related technologies, the roadheader and transfer conveyor are fixedly connected. However, this connection method requires operators to frequently disassemble and reassemble the transfer conveyor after the roadheader turns at different angles, resulting in high labor intensity for workers, low tunneling efficiency, and long construction periods.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is a reference appendix. Figures 1 to 4 This invention describes a turning device and a coal mining equipment according to embodiments of the present invention.

[0028] like Figures 1 to 4 As shown, the turning device of this utility model embodiment includes: a traction member 1, a pin (not shown), a fixing frame 2, and a base 3. The traction member 1 is provided with a pin hole 11, which passes through the traction member 1 in the vertical direction. The pin is rotatably inserted through the pin hole 11, and the rotation axis of the pin is parallel to the vertical direction. The pin is used to connect to a roadheader. The traction member 1 and the fixing frame 2 are both provided on the base 3. The fixing frame 2 is provided with a fixing part 22, which is used to connect to a transfer machine.

[0029] According to the turning device of the present invention, since the pin shaft is rotatably inserted through the pin shaft hole 11 and the rotation axis of the pin shaft is parallel to the vertical direction, and the pin shaft is used to connect the roadheader, the base 3 and the fixed frame 2 can remain relatively stationary when the roadheader turns to different angles, that is, the transfer machine can remain stationary. Therefore, there is no need for operators to frequently disassemble the transfer machine, which is beneficial to improving tunneling efficiency and saving manpower.

[0030] Optionally, the traction member 1 is rotatable relative to the base 3 along a first axis, the first axis being perpendicular to a first direction (e.g., Figure 2 The first direction (direction A) is parallel to the vertical direction, and the second direction is orthogonal to the vertical direction. That is to say, the traction component 1 can make pitching motion relative to the base 3. Therefore, when the angle of the roadheader changes in the vertical direction, the base 3 can remain relatively stationary, thereby avoiding frequent unloading and transfer.

[0031] like Figure 1 and Figure 2 As shown, both the traction member 1 and the fixing frame 2 are detachably connected to the base 3, and the traction member 1 and the fixing frame 2 are along the second direction (e.g., Figure 1 The components are arranged at intervals in direction B, with the first direction, second direction, and up / down direction being orthogonal to each other. Since both the traction component 1 and the fixing frame 2 are detachably connected to the base 3, the manufacturing of the turning device is convenient, and the cost of subsequent maintenance and replacement is low.

[0032] Optionally, the position of the fixing frame 2 relative to the base 3 along the second direction is adjustable, thereby expanding the application range of the turning device to meet the installation work of different types of roadheaders and transfer machines, which is beneficial to improving the compatibility of the turning device.

[0033] For example, the fixing frame 2 is provided with a plurality of first holes 211, which are spaced apart along a second direction and penetrate the fixing frame 2 in a vertical direction. The base 3 is provided with a plurality of second holes 31, which are spaced apart along the second direction and penetrate the base 3 in a vertical direction. The bending device also includes a first fastener, which passes through the first holes 211 and the second holes 31 in a vertical direction. For example, the first fastener can be a threaded part or a pin structure.

[0034] When it is necessary to adjust the position of the fixing frame 2 and the base 3 along the second direction, the first fastener can be loosened, and then the first hole 211 and the second hole 31 at different positions can be aligned. After the fixing frame 2 and the base 3 are adjusted to the set position, the first fastener can be inserted into the corresponding first hole 211 and second hole 31 to fix the fixing frame 2 and the base 3. This can improve the convenience of adjusting the turning device, and the structure design is simple and the connection is reliable.

[0035] Optionally, such as Figure 2 and Figure 4 As shown, the fixing frame 2 includes a support plate 21 and two fixing parts 22, which are arranged at intervals along a second direction on the support plate 21. The presence of two fixing parts 22 improves the robustness of the connection between the fixing frame 2 and the transfer machine.

[0036] For example, such as Figure 2 and Figure 4As shown, the fixing part 22 includes a first ear seat 221 and a second ear seat 222. The first ear seat 221 and the second ear seat 222 are arranged at intervals along a second direction and define a clamping cavity. The first ear seat 221 has a third hole 2211, which passes through the first ear seat 221 along the second direction. The second ear seat 222 has a fourth hole 2221, which passes through the second ear seat 222 along the second direction. The third hole 2211 and the fourth hole 2221 are arranged opposite to each other along the second direction. It can be understood that the transfer machine has a transfer machine tail frame, and the legs of the transfer machine tail frame are located between the first ear seat 221 and the second ear seat 222. The turning device also includes a second fastener (such as a threaded part), which passes through the first ear seat 221, the legs of the frame structure, and the second ear seat 222 in sequence, thereby fixing the transfer machine.

[0037] For example, at least one of the first ear seat 221 and the second ear seat 222 has a reinforcing rib (not shown) at the contact position with the support plate 21. For example, the first ear seat 221 has a reinforcing rib at the contact position with the support plate 21, and for another example, a reinforcing rib is provided between the second ear seat 222 and the support plate 21. This can improve the connection strength between the first ear seat 221 and the second ear seat 222 and the support plate 21, and improve the load-bearing capacity of the fixing frame 2.

[0038] For example, such as Figure 3 As shown, the base 3 has a cavity 32 inside, which can reduce the weight of the base 3 while ensuring that the base 3 has sufficient structural strength.

[0039] Another embodiment of the coal mining equipment of this utility model includes: a roadheader, a transfer machine, and a turning device. The turning device is the turning device of this utility model. The pin shaft is connected to the roadheader, and the fixing part 22 of the fixing frame 2 is connected to the transfer machine.

[0040] According to the coal mining equipment of the present invention, since the pin shaft is rotatably installed through the pin shaft hole 11 and the rotation axis of the pin shaft is parallel to the vertical direction, and the pin shaft is used to connect the roadheader, the base 3 and the fixed frame 2 can remain relatively stationary when the roadheader turns to different angles, that is, the transfer machine can remain stationary. Therefore, there is no need for operators to frequently disassemble the transfer machine, which is beneficial to improving tunneling efficiency and saving manpower.

[0041] For example, the coal dropping area on the tail frame of the transfer machine is equipped with a highly elastic rubber buffer strip to mitigate the impact caused by coal leakage on both sides, and a coal baffle is installed on the top of the tail frame of the transfer machine to prevent the coal from falling outside the frame.
