[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] The following describes the adjustable support for coal mine belt transportation according to an embodiment of the present invention with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, the adjustable support for coal mine belt transportation according to an embodiment of the present invention includes a support frame 1, a buffer frame 2 and a telescopic canopy 3.

[0027] The support frame 1 includes a support plate 11 and a plurality of support seats 12. The length direction of the support plate 11 is a first direction, and the plurality of support seats 12 are located on both sides of the support plate 11 in the first direction, the first direction is perpendicular to the up-down direction, and each support seat 12 is provided with a guide rod 13 and a telescopic cylinder 14. The first direction can be a left-right direction, and the left-right direction and the up-down direction are shown by arrows in the figure. For example, the length direction of the support plate 11 is a left-right direction, and the plurality of support seats 12 are located on both sides of the support plate 11 in the left-right direction. The bottom of the support seat 12 is in contact with the ground, and the plurality of support seats 12 are connected through the support plate 11. The support plate 11 is provided with a rib (not shown in the figure) connected to the support seat 12, so as to improve the structural strength of the support frame 1.

[0028] The buffer frame 2 is located above the support frame 1. The buffer frame 2 includes a buffer plate 21 and a plurality of buffer seats 22. The length direction of the buffer seat 22 is a first direction. The plurality of buffer seats 22 are located on both sides of the buffer plate 21 in the first direction. The buffer plate 21 is used to fix the head frame of the conveyor so as to support the head frame of the conveyor. For example, the length direction of the buffer seat 22 is a left-right direction. The plurality of buffer seats 22 are located on both sides of the buffer plate 21 in the left-right direction. The buffer plate 21 is provided with a rib plate (not shown in the figure) connected to the buffer seat 22 so as to improve the structural strength of the buffer frame 2.

[0029] Multiple buffer seats 22 are matched with multiple support seats 12 in a one-to-one manner, and each buffer seat 22 has a guide groove facing the lower side. The guide rods 13 of the multiple support seats 12 extend into the guide groove of the buffer seat 22 in a one-to-one manner. The shape and size of the guide rod 13 are adapted to the shape and size of the guide groove, so that the guide rod 13 can slide in the guide groove in the up and down directions and can limit the buffer seat 22.

[0030] The telescopic part of the telescopic cylinder 14 of each support seat 12 is used to support the bottom of the corresponding buffer seat 22. An elastic member 15 is provided between the telescopic part of the telescopic cylinder 14 of each support seat 12 and the bottom of the corresponding buffer seat 22. The elastic member 15 can be elastically deformed in the up and down directions. Specifically, the telescopic part of the telescopic cylinder 12 can move in the up and down directions. When the telescopic part extends upward, it can drive the buffer seat 22 to move upward, thereby driving the buffer frame 2 to move upward. In order to adjust the height of the head frame of the conveyor in the up and down directions, so as to adapt to different environments and equipment. And an elastic member 15 is provided between the telescopic part and the bottom of the buffer seat 22, so that when the coal block impacts the conveyor, the elastic member 15 can provide a certain buffering force for the conveyor, so as to reduce the probability of damage to the conveyor and improve the durability of the conveyor.

[0031] Therefore, the adjustable support for coal mine belt conveyor according to the embodiment of the present invention has the advantages of being able to adjust the head frame height of the conveyor and improving buffering.

[0032] like Figure 2 As shown, in some embodiments, a support rod 16 is provided at the top of the telescopic portion of the telescopic cylinder 14. The elastic member 15 is a spring, which is sleeved on the support rod 16. The buffer seat 22 has a support groove facing downward, and the top of the support rod 16 can be inserted into the support groove of the corresponding buffer seat 22. The support rod 16 is slidably connected with the buffer seat 22 in the up-down direction, and the elastic member 15 is located between the support seat 12 and the buffer seat 22 in the up-down direction. Specifically, the spring is located outside the support groove, and the top of the spring is connected to the bottom of the buffer seat 22. When the telescopic portion of the telescopic cylinder 14 moves upward, the support rod 16 extends into the support groove, and the telescopic portion of the telescopic cylinder 14 pushes the spring and the buffer seat 22 to move upward.

[0033] In some embodiments, a plurality of connection platforms 23 for connecting to the head frame of the transporter are provided on the buffer plate 21. Specifically, the connection platform 23 can support the head frame and can be rotatably connected to the head frame by bolts.

[0034] In some embodiments, a plurality of support seats 12 are provided on each side of the support plate 11 in the first direction; a plurality of buffer seats 22 are provided on each side of the buffer plate 21 in the first direction. Thus, the support of the headstock can be made more stable. For example, two support seats 12 are provided on each side of the support plate 11 in the first direction; two buffer seats 22 are provided on each side of the buffer plate 21 in the first direction.

[0035] In some embodiments, the guide rod 13 and the support rod 16 are both circular rod bodies, and the guide groove and the support groove are both circular groove bodies.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the telescopic awning 3 includes a tarpaulin and a plurality of frames 31. The plurality of frames 31 are sequentially arranged in the second direction, a telescopic connecting rod is arranged between two adjacent frames 31, and the tarpaulin is arranged on the plurality of frames 31. Specifically, the telescopic connecting rod includes a hinged first connecting rod and a second connecting rod, and the two adjacent frames 31 can be telescoped through the first connecting rod and the second connecting rod.

[0037] The first frame located at the side of the plurality of frames 31 is detachably connected to the buffer frame 2, and any two of the first direction, the second direction and the up-down direction are perpendicular. Specifically, the size of the buffer frame 2 in the first direction is larger than the size of the transporter, and the first frames located at the side of the plurality of frames 31 are connected, so that the retractable canopy 3 can be unfolded in rainy days to block rain, thereby reducing rainwater entering the transporter to protect the equipment. For example, the second direction is the front-to-back direction, and the plurality of frames 31 are arranged in sequence in the front-to-back direction, and the retractable canopy 3 can be retracted in the front-to-back direction.

[0038] In some embodiments, the two columns 32 of the first frame 31 are respectively detachably mounted on the buffer seats 22 on both sides of the two buffer plates 21. Specifically, a connecting plate 33 is disposed at the bottom of the columns 32 of the first frame 31, and the connecting plate 33 can be detachably connected to the buffer seat 22 by bolts 34.

[0039] In some embodiments, the bottom of the column 32 of the frame 31 is provided with a running wheel 35, and the running wheel 35 of the column 32 of the first frame 31 is matched on the track of the buffer seat 22. Specifically, the track can be set on both sides of the first direction of the conveyor, and after the retractable canopy 3 is unfolded, the running wheel 35 of the column 32 can be matched in the track.
