Description
TECHNICAL FIELD
[0001] The present application relates to the field of engineering machinery, in particular to a mining trolley. BACKGROUND
[0002] The workload of drilling holes in mining is very large, and improving the drilling speed and the accuracy of hole position becomes one of the keys to speed up the project progress. In narrow roadway, the equipment is not convenient to move, and it is impossible to realize the drilling work in the fan-shaped cross-section range. At the same time, if the vehicle body is moved, the hole position in the early stage cannot be positioned, and there is deviation from the hole position requirement in the mine construction drawing, which cannot realize accurate mining, and it is difficult to move the vehicle body in the narrow roadway and consumes a lot of time. CONTENT OF THE UTILITY MODEL
[0003] The embodiment of the present application provides a mining trolley, which is compact in structure, can increase the horizontal travel stroke, and reduces the cost.
[0004] The present application provides a mining trolley, which comprises a vehicle frame, a pitching platform, a pitching oil cylinder, a translation platform, an execution mechanism, a four-bar linkage mechanism and an extension piece. The pitching platform is hinged to the vehicle frame, and the two ends of the pitching oil cylinder are respectively hinged to the vehicle frame and the pitching platform. The translation platform is movably arranged on the pitching platform in the horizontal direction. The execution mechanism is arranged on the translation platform, and is used for drilling. The four-bar linkage mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. One end of the first connecting rod is hinged to the pitching platform, the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the translation platform. One end of the third connecting rod and one end of the fourth connecting rod are hinged to the extension end of the extension piece. The other end of the third connecting rod is hinged to the first connecting rod, and the other end of the fourth connecting rod is hinged to the second connecting rod. The extension piece is arranged on the pitching platform, and the extension direction of the extension piece is consistent with the moving direction of the translation platform.
[0005] The mining trolley of the present application has at least the following beneficial effects:
[0006] The mining trolley of the present application comprises a vehicle frame, a pitching platform, a pitching oil cylinder, a translation platform, an execution mechanism, a four-bar linkage mechanism and an extension piece. The pitching platform pitches and drives the four-bar linkage mechanism to move through the extension piece. The four-bar linkage mechanism drives the translation platform to move horizontally in the roadway, so that all hole drilling work in the fan-shaped range can be successfully completed without moving the mining trolley in the narrow roadway. In addition, through the amplification effect of the four-bar linkage mechanism, the translation platform can reciprocate from the left end to the right end, so that the structure of the whole vehicle is compact and the horizontal working range is large.

[0023] As shown in Figure 1 and Figure 2 The present embodiment discloses a mining platform truck, comprising a frame 10, a pitching platform 20, a pitching cylinder 30, a translation platform 40, an actuator 50, a four-bar linkage mechanism 60, and an extension piece 70, specifically as follows:
[0024] As shown in Figure 1 The frame 10 is the main structure of the mining platform truck, and a walking mechanism is arranged below the frame 10, which is not described here.
[0025] As shown in Figure 1 The pitching platform 20 is hinged at the end position of the frame 10, and two sets of parallelly arranged pitching cylinders 30 are used to drive the pitching platform 20 to perform up-and-down pitching action, which can increase the drilling range and retract the pitching platform 20, and also can reduce the overall height of the vehicle.
[0026] As shown in Figure 1As shown, one end of the luffing oil cylinder 30 is hinged to the vehicle frame 10, and the other end of the luffing oil cylinder 30 is hinged to the back side of the luffing platform 20. The luffing action of the luffing platform 20 is realized by the extension and retraction of the luffing oil cylinder 30. When the luffing oil cylinder 30 is fully retracted, the luffing platform 20, together with the translation platform 40 and the execution mechanism 50, is lowered to the lowest position in the transportation state. When the luffing oil cylinder 30 is extended, the luffing platform 20 and the luffing oil cylinder 30 form a triangular structure, which can ensure that the execution mechanism 50 remains perpendicular to the ground.
[0027] As shown in Figure 3 , the translation platform 40 is movably arranged on the luffing platform 20, and the moving direction of the translation platform 40 is horizontal and transverse, i.e. the width direction of the roadway. The movable arrangement of the translation platform 40 on the luffing platform 20 can refer to the existing sliding groove and sliding block cooperation mode, or can use the guide slide column 11 and sliding sleeve 41 sliding cooperation mode in the present embodiment. Specifically, the guide slide column 11 is arranged on the luffing platform 20, and the length direction of the guide slide column 11 is configured to be horizontal and transverse. The sliding sleeve 41 is coaxially arranged on the guide slide column 11, and is in sliding cooperation with the guide slide column 11.
[0028] As shown in Figure 3 , in some preferred embodiments, a guide plate 12 is arranged below the vehicle frame 10, and the length direction of the guide plate 12 is consistent with the length direction of the guide slide column 11. When the luffing platform 20 is erected, the guide plate 12 is located directly below the guide slide column 11. Two clamping plates 42 are arranged below the translation platform 40, and the two clamping plates 42 are respectively located on the two sides of the width direction of the guide plate 12, i.e. the guide plate 12 is arranged between the two clamping plates 42. Through the cooperation of the clamping plate 42 and the guide plate 12, the degree of freedom of the translation platform 40 rotating around the guide slide column 11 can be limited.
[0029] As shown in Figure 4 , in some preferred embodiments, an anti-wear clamping block 43 is arranged on the inner side of the clamping plate 42 (i.e. the side facing the guide plate 12), and the anti-wear clamping block 43 can be in sliding contact with the horizontal side wall surface of the guide plate 12. The anti-wear clamping block 43 can prevent direct contact between the clamping plate 42 and the guide plate 12, thereby preventing wear, and can also absorb the vibration generated during the operation of the execution mechanism 50.
[0030] As shown in Figure 3 and Figure 4 , in some preferred embodiments, the two clamping plates 42 are connected by a connecting piece 44 (such as a threaded connecting piece or the like) to maintain a certain distance between the two clamping plates 42.
[0031] As shown in Figure 4As shown, the actuator 50 is used to drill holes in the tunnel. The actuator 50 includes a rotating component 51 and a punching component 52. The rotating component 51 (such as a rotary motor, etc.) is arranged on the translation platform 40, and the punching component 52 is arranged on the output end of the rotating component 51. The punching component 52 is used to drill holes in the tunnel. The rotating component 51 can drive the punching component 52 to rotate a certain angle around the horizontal direction.
[0032] like Figure 5 As shown, the four-bar linkage 60 includes a first link 61, a second link 62, a third link 63 and a fourth link 64; the first link 61, the second link 62, the third link 63 and the fourth link 64 are connected to form the four-bar linkage 60, wherein one end of the first link 61 is hinged to the first support 13 provided on the pitch platform 20, the other end of the first link 61 is hinged to one end of the second link 62, the other end of the second link 62 is hinged to the second support 45 provided on the sliding sleeve 41, one end of the third link 63 and the fourth link 64 are both hinged to the telescopic end of the telescopic member 70, the other end of the third link 63 is hinged to the first link 61, and the other end of the fourth link 64 is hinged to the second link 62.
[0033] like Figure 5 As shown, in some preferred embodiments, the first support 13 is detachably arranged on the pitching platform 20. Specifically, the pitching platform 20 is provided with a plurality of connecting holes (not marked) at horizontal lateral intervals. The first support 13 can be connected to the connecting holes by connecting bolts and other components, and the first support 13 can be arbitrarily selected to be connected and fixed with connecting holes in different positions according to actual conditions, so as to adapt to different working conditions.
[0034] like Figure 5 As shown, in some preferred embodiments, the other end of the third link 63 is hinged to the middle position of the first link 61, and the other end of the fourth link 64 is hinged to the middle position of the second link 62, so that the four-link mechanism 60 can maximize the displacement stroke of the translation platform 40.
[0035] like Figure 5 As shown, the telescopic member 70 is arranged on the pitch platform 20, and the telescopic direction of the telescopic member 70 is configured to be horizontal. When the telescopic member 70 is extended, the four-bar linkage 60 is pushed, and the translation platform 40 is driven by the four-bar linkage 60 to translate to the left. Conversely, when the telescopic member 70 is retracted, the translation platform 40 is driven by the four-bar linkage 60 to move to the rightmost end.
[0036] like Figure 5As shown, the telescopic part 70 is configured as a telescopic oil cylinder, which is arranged on the pitching platform 20, and the telescopic rod of the telescopic oil cylinder is hinged to one end of the third connecting rod 63 and the fourth connecting rod 64. The inside of the telescopic oil cylinder is provided with a magnetic hysteresis displacement sensor 71 for measuring the telescopic displacement of the telescopic oil cylinder, so as to accurately position the perforating position. The magnetic hysteresis displacement sensor can be built in the oil cylinder, which is lower in cost, better in protection, longer in service life.
[0037] The above is merely a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working processes of the above-described system, modules and units can refer to the corresponding processes in the foregoing method embodiments, which will not be described herein again. It should be understood that the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application.
