Description

Technical Field

[0001] The utility model relates to the technical field of coal mine conveying, and particularly provides an adjustable support and a coal mine conveyor. Background Art

[0002] Coal mine conveying is one of the necessary processes in coal mine mining operations. The existing coal mine conveying is realized through a belt conveyor; its operation scenarios include: conveying the mined coal from the underground coal mining tunnel to the ground; and conveying the coal from the ground to the transport truck.

[0003] In the latter scenario, most of the existing coal mine conveyors are fixedly installed on the ground, which leads to the need for transport trucks to queue up in turn, and a single vehicle parks directly below the belt conveyor, so that the coal can be transported out of the coal mining area.

[0004] However, this operation method is inefficient, and it takes a long time for the transport truck to reverse and adjust its body posture directly below the belt conveyor.

[0070] The following combines Figures 1 to 14 the embodiments shown to describe the technical solutions of the present utility model:

[0071] An embodiment of the present utility model provides an adjustable support, as Figures 1 to 3 shown, including: an arc-shaped track 1, a first sliding mechanism 2, a support telescopic mechanism 3, a support main body 4, a hinge seat 5, a base 6, and a control unit 7;

[0072] Wherein, the first sliding mechanism 2 is arranged on the arc-shaped track 1 and can reciprocate along the arc-shaped track 1; one end of the support telescopic mechanism 3 is hinged to the first sliding mechanism 2; the support main body 4 has an input end 401 and an output end 402, and the other end of the support telescopic mechanism 3 is hinged near the output end 402; the hinge seat 5 is hinged to the input end 401 of the support main body 4; the hinge seat 5 is rotatably installed on the base 6; the control unit 7 is electrically connected to the first sliding mechanism 2 and the support telescopic mechanism 3 respectively; wherein, the base 6 and the arc-shaped track 1 are in the same horizontal plane.

[0073] It can be understood that the first sliding mechanism 2 can be designed as a structure in which a linear guide rail cooperates with a slider, and its reciprocating motion is realized by motor drive. Other mechanism combinations can also be used, as long as the function of driving the support telescopic mechanism 3 mounted on its surface to reciprocate on the arc-shaped track 1 can be satisfied;

[0074] In this embodiment, as Figure 2 shown, the first sliding mechanism 2 is arranged on the arc-shaped track 1, one end of the support telescopic mechanism 3 is hinged to the first sliding mechanism 2, and the output end 402 of the support main body 4 is hinged to the support telescopic mechanism 3, so that when the first sliding mechanism 2 reciprocates on the arc-shaped track 1, it can drive the support telescopic mechanism 3 and the support main body 4 to reciprocate together, realizing that the support main body 4 can reciprocate at different positions at the same height;

[0075] The hinge seat 5 is hinged to the input end 401 of the support main body 4, and at the same time, the hinge seat 5 is rotatably installed on the base 6, so that when the output end 402 of the support main body 4 moves up and down due to the support telescopic mechanism 3, the input end 401 of the support main body 4 can rotate at the base 6;

[0076] The control unit 7 is electrically connected to the first sliding mechanism 2 and the support telescopic mechanism 3 respectively, and can independently control the reciprocating motion of the first sliding mechanism 2 and the up and down motion of the support telescopic mechanism 3; wherein, the base 6 and the arc-shaped track 1 are in the same horizontal plane, ensuring that when the support telescopic mechanism 3 is adjusted, the support main body 4 always has a certain elevation angle relationship with the ground.

[0077] An adjustable support provided by the present utility model, by arranging a first sliding mechanism 2 capable of reciprocating motion and a support telescopic mechanism 3 capable of telescoping up and down under a traditional belt conveyor, enables the support to carry out coal mine transportation at different positions, effectively solving the problem of low connection efficiency between the traditional belt conveyor and the transport truck. Specifically:

[0078] By providing the arc-shaped track 1, a track basis is provided for the reciprocating motion of the first sliding mechanism 2; by hinging and supporting the telescopic mechanism 3 on the first sliding mechanism 2 and hinging the support body 4 on the telescopic mechanism 3, when the first sliding mechanism 2 reciprocates, it drives the telescopic mechanism 3 to reciprocate, thereby driving the support body 4 to reciprocate. Therefore, the support body 4 can meet the conveying requirements at the same height but different positions; by providing the telescopic mechanism 3, the support body 4 can be driven to move up and down. Therefore, the support body 4 can meet the conveying requirements at different heights;

[0079] By providing the support body 4, a coal mine conveyor can be installed on the support body 4 to realize the transportation of coal mines; by providing a hinge seat 5 at the input end 401 of the support body 4, a rotation base point is provided for the rotation of the support body 4;

[0080] By fixing the base 6 to the ground, the problem that the input end 401 of the support body 4 tilts due to coal accumulation at the output end 402 of the support body 4 is avoided; by providing a control unit 7 electrically connected to the first sliding mechanism 2 and the telescopic mechanism 3, the reciprocating motion of the first sliding mechanism 2 and the up and down motion of the telescopic mechanism 3 can be regulated step by step, so that the adjustable support can be applied to coal mine transportation work at multiple positions; by arranging the base 6 and the arc-shaped track 1 on the same horizontal plane, when the telescopic mechanism 3 is adjusted, it is ensured that the support body 4 always has a certain elevation angle relationship with the ground.

[0081] According to the adjustable support provided by the embodiment of the present invention, as Figure 4 shown, the first sliding mechanism 2 includes:

[0082] A sliding seat 201, slidably installed on the arc-shaped track 1, and one end of the telescopic mechanism 3 is hinged to the sliding seat 201;

[0083] A first driving part 202, drivingly connected to the sliding seat 201, for providing a reciprocating motion force to the sliding seat 201, and the first driving part 202 is electrically connected to the control unit 7.

[0084] In this embodiment, the first sliding mechanism 2 is preferably a combination of the sliding seat 201 and the first driving part 202. Among them, the sliding seat 201 is used to carry the telescopic mechanism 3, and the first driving part 202 drives the sliding seat 201 to reciprocate, and then drives the telescopic mechanism 3 hinged on the sliding seat 201 to reciprocate. Therefore, the support body 4 connected to the telescopic mechanism 3 can also move longitudinally and reciprocally, so that the support body 4 can meet the transportation requirements at the same height but different positions.

[0085] According to the adjustable support provided by the embodiment of the present invention, as Figures 5 to 8As shown in the figure, the arc track 1 includes a bottom plate 101 and a guide plate 102. The guide plate 102 is an arc-shaped plate and is vertically installed on the bottom plate 101. Multiple first ball chutes 1021 along the radian direction are provided on both side surfaces of the guide plate 102.

[0086] The sliding seat 201 includes:

[0087] A base plate 2011 spanning across the guide plate 102;

[0088] Limiting plates 2012, at least two of them, are all arc-shaped and are fixedly installed on the lower surface of the base plate 2011 in parallel, and the guide plate 102 is clamped between the two limiting plates 2012. Multiple second ball chutes 2013 are provided on the opposite surfaces of the two limiting plates 2012 along the radian direction;

[0089] Multiple balls 2014 are respectively clamped between the first ball chutes 1021 and the second ball chutes 2013;

[0090] A roller assembly 2015 is arranged below the base plate 2011 and is fixedly connected to the base plate 2011 for supporting the base plate 2011 to move.

[0091] In this embodiment, the arc track 1 is a combination of the bottom plate 101 and the guide plate 102. The bottom plate 101 is a basic load-bearing plate, and the guide plate 102 restricts the movement track of the sliding seat 201;

[0092] The sliding seat 201 is preferably a combination of the base plate 2011, the limiting plates 2012, the balls 2014 and the roller assembly 2015. Among them, at least two limiting plates 2012 are provided and are installed in parallel on both sides of the guide plate 102 to prevent the sliding seat 201 from tipping over due to problems such as weight during use and thus getting out of the restraint of the guide plate 102, so that the support telescopic mechanism 3 moves uncontrollably, resulting in risks in coal mine transportation on the support main body 4;

[0093] On the relative sliding surfaces of the guide plate 102 and the limiting plates 2012, corresponding first ball chutes 1021 and second ball chutes 2013 are respectively processed. The track space formed by the two groups of chutes is embedded with balls 2014, and the rolling friction replaces the sliding contact between traditional planes, significantly reducing the movement resistance; the roller assembly 2015 is used to drive the base plate 2011 to perform reciprocating motion, so that the support telescopic mechanism 3 hinged on the base plate 2011 can also perform reciprocating motion, and further drive the support main body 4 to perform reciprocating motion.

[0094] According to the adjustable support provided by the embodiment of the present invention, as Figure 9 shown, the first driving part 202 includes:

[0095] The driving sprocket 2021 has at least one and is rotatably arranged at one end of the arc track 1;

[0096] The first driving motor 2022 is drivingly connected to the driving sprocket 2021;

[0097] The driven sprocket 2023 has at least one and is rotatably arranged at the other end of the arc track 1;

[0098] There are a plurality of guiding sprockets 2024, which are respectively rotatably arranged on the arc track 1 in sequence along the radian direction of the arc track 1;

[0099] The chain 2025 is respectively cooperatively connected with the driving sprocket 2021, the driven sprocket 2023 and the guiding sprockets 2024;

[0100] Wherein, the single-sided chain 2025 between the driving sprocket 2021 and the driven sprocket 2023 is fixedly connected to the sliding seat 201.

[0101] It can be understood that the first driving part 202 can be a mechanical structure in which a piston cylinder controlled by an electromagnetic valve drives to perform an axial linear motion, and a mechanical stopper or a magnetic switch is used to restrict its moving distance to achieve fixed-point control. Therefore, the first driving part 202 can drive the sliding seat 201 to achieve reciprocating motion.

[0102] In this embodiment, the guiding sprockets 2024 are arranged and installed in sequence along the radian direction of the arc track 1, and the driving chain 2025 is driven along the arc track of the arc track 1; the single-sided chain 2025 between the driving sprocket 2021 and the driven sprocket 2023 is fixedly connected to the sliding seat 201, and synchronously pulls the sliding seat 201 to move during movement, so as to realize the reciprocating motion of the sliding seat 201 along the arc track of the arc track 1.

[0103] According to the adjustable bracket provided by the embodiment of the present invention, as Figure 10 and Figure 11 shown, it further includes a locking part 8, and the locking part 8 includes:

[0104] There are a plurality of locking holes 801, which are sequentially opened on the upper end surface of the guiding plate 102;

[0105] There is at least one electromagnetic lock pin 802, which is arranged on the substrate 2011. The pin of the electromagnetic lock pin 802 can penetrate through the substrate 2011 and extend into the locking hole 801, and the electromagnetic lock pin 802 is electrically connected to the control unit 7.

[0106] In this embodiment, by arranging a plurality of locking holes 801 in an array on the upper end surface of the guide plate 102, when the sliding seat 201 moves to any required position according to requirements, it can be rigidly fixed by the locking portion 8; at the same time, an electromagnetic locking pin 802 is provided. Through the arrangement that the electromagnetic locking pin 802 penetrates and is fixed on the substrate 2011, when the substrate 2011 reaches the required position, the electromagnetic locking pin 802 can be lowered into the locking hole 801 by means of the control unit 7 to achieve the functions of locking and fixing. When it is necessary to move to the next position, the control of the electromagnetic locking pin 802 by the control unit 7 is turned off. After power-off, the electromagnetic locking pin 802 moves upward and away from the locking hole 801 by relying on the return spring. After moving the substrate 2011 to the required position by using the first driving portion 202, the above actions are repeated after power-on, so that the substrate 2011 can stop and be fixed at any position of the guide plate 102.

[0107] According to the adjustable bracket provided by the embodiment of the present invention, as Figure 12 shown, it further includes a second sliding mechanism 9, and the second sliding mechanism 9 includes:

[0108] A ball screw 901 is arranged along the direction from the input end 401 to the output end 402 of the bracket main body 4 and is rotatably installed on the bracket main body 4;

[0109] A second driving motor 902 is drivingly connected to the ball screw 901;

[0110] A ball nut 903 is in threaded cooperation with the ball screw 901 and is hinged to the other end of the support telescopic mechanism 3.

[0111] It can be understood that the second sliding mechanism 9 can be designed as a structure in which a linear guide rail and a slider cooperate to realize reciprocating motion through motor drive, or it can also be other structures that can be hinged to the support telescopic mechanism 3 and drive the support telescopic mechanism 3 to move up and down, so as to drive the bracket main body 4 to be at different heights and realize transportation at different heights in the coal mine.

[0112] In this embodiment, the second sliding mechanism 9 is preferably a combination of a ball screw 901, a second driving motor 902 and a ball nut 903. Among them, through the arrangement that the ball screw 901 is rotatably installed on the bracket main body 4, the ball nut 903 is rotationally driven to linearly move along the input end 401 to the output end 402 of the bracket main body 4; through the arrangement of the second driving motor 902, the rotational force is provided for the rotation of the ball screw 901; through the arrangement that the ball nut 903 is hinged to one end of the support telescopic mechanism 3, when the ball nut 903 makes a linear motion on the ball screw 901, the support telescopic mechanism 3 is driven to move synchronously.

[0113] According to the adjustable bracket provided by the embodiment of the present invention, as Figure 1 shown, the support telescopic mechanism 3 is a plurality of parallel hydraulic telescopic rods.

[0114] In this embodiment, the support telescopic mechanism 3 is a hydraulic telescopic rod, which can be adjusted by a control valve to be telescopic to meet various height requirements. Since the output end 402 of the support body 4 is hinged to the support telescopic mechanism 3, the output end 402 of the support body 4 can be adjusted to different height positions, realizing coal mine transportation at different height positions; at the same time, the setting of the hydraulic telescopic rod can make the whole support lighter, control intelligent and reduce energy loss.

[0115] The embodiment of the present invention also provides a coal mine conveyor, as Figure 13 and Figure 14 shown, including the adjustable support described above, and further including:

[0116] The second driving part 10 is arranged on the support body 4;

[0117] The driving pulley 11 is rotatably arranged on the support body 4 and is drivingly connected to the second driving part 10;

[0118] The driven pulley 12 is rotatably arranged on the support body 4;

[0119] The conveyor belt 13 is in a circulating driving fit with the driving pulley 11 and the driven pulley 12 respectively.

[0120] It can be understood that the second driving part 10 can be a DC motor, which is directly installed on the support body 4 or is arranged at the input end 401 of the support body 4 through a belt and then indirectly connected to the motor, etc., as long as it can drive the coal mine conveyor to operate.

[0121] In this embodiment, as Figure 13 shown, the second driving part 10 adopts a DC motor, which is fixedly installed on the support body 4 and is used to drive the driving pulley 11 to rotate; both the driving pulley 11 and the driven pulley 12 are rotatably connected to the support body 4 through bearings, and are meshed and driven by the conveyor belt 13 therebetween. When the second driving part 10 drives the driving pulley 11 to rotate, the conveyor belt 13 moves synchronously under the friction force of the driving pulley 11, so as to convey the coal from the input end 401 of the support body 4 to the output end 402, completing the automatic transportation of the coal mine.
