[0031] The 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 cannot be understood as limiting the present invention.

[0032] like Figures 1 to 6 As shown, the hydraulic support 100 of the embodiment of the utility model includes a top beam 1, a guard rail 2, a power assembly 3 and a detector 4. The guard rail 2 is rotatably connected to the top beam 1; the power assembly 3 is used to drive the guard rail 2 to rotate relative to the top beam 1; the detector 4 is movably connected to the top beam 1, and the power assembly 3 is transmission-connected to the detector 4 to drive the detector 4 to move relative to the top beam 1.

[0033] The hydraulic support 100 of the embodiment of the utility model sets the detector 4 on the top beam 1 so that the detector 4 is above the coal mining passage 200, thereby reducing the detection blind area of ​​the coal mining passage 200, and can detect the side of the coal mining machine, the scraper chute and other positions to monitor the operation of the coal mining machine. In addition, the detector 4 is connected to the power assembly 3 in a transmission manner, and the detector 4 can be controlled to move while the power assembly 3 drives the guard 2 to rotate, which is more conducive to controlling the position movement of the detector 4 to prevent the coal mining machine from colliding with the detector 4 when it is running.

[0034] like Figure 1 As shown, the area where the coal mining machine operates is the coal mining channel 200. A plurality of hydraulic supports 100 are provided along the length direction of the coal mining channel 200. The detectors 4 on the hydraulic supports 100 can perform single-point detection on the coal mining channel 200. The detection areas of the detectors 4 on the plurality of hydraulic supports 100 can cover the entire coal mining channel 200, thereby reducing the detection blind spots, and being able to monitor the sides of the coal mining machine, the scraper chute, the coal wall and other areas in real time to prevent accidents. At the same time, when one of the detectors 4 is damaged, the remaining detectors 4 can continue to work, and the maintenance and replacement of the detectors 4 are relatively convenient.

[0035] like Figure 1 and Figure 2 As shown, driven by the power assembly 3, the guard 2 has an extended state and a retracted state. When the coal mining machine is not mining the area, the guard 2 is in the extended state to support the coal wall that is not being mined. When the coal mining machine is mining the coal wall in the area, the guard 2 switches to the retracted state to prevent the coal mining machine from colliding with the guard 2. According to the different inclination angles of the coal wall, the angle between the guard 2 and the top beam 1 in the extended state is also different.

[0036] Optionally, the detector 4 is at least one of a dynamic image observation device, a distance measurement device, a vibration measurement device, a coal gangue identification band detection device, etc., wherein the dynamic image observation device is at least one of a video recording device, an infrared thermal imaging device, etc., and the distance measurement device is at least one of a distance sensor, a radar, etc.

[0037] In some embodiments, the hydraulic support 100 further includes a transmission assembly 5 , and the power assembly 3 is connected to the detector 4 through the transmission assembly 5 .

[0038] When the power component 3 drives the guardrail 2 to rotate relative to the top beam 1, the detector 4 can be driven to move through the transmission component 5, so that the detector 4 and the guardrail 2 are linked; when the coal mining machine passes through the hydraulic support 100, the detector 4 moves with the rotation of the guardrail 2 to prevent the detector 4 from colliding with the coal mining machine.

[0039] In some embodiments, Figure 2 As shown, the transmission assembly 5 includes a first connecting rod 51 and a second connecting rod 52, one end of the first connecting rod 51 is rotatably connected to the top beam 1, one end of the second connecting rod 52 is rotatably connected to the guardrail 2, the other end of the first connecting rod 51 and the other end of the second connecting rod 52 are rotatably connected through a rotating shaft 53, and the detector 4 is connected to the first connecting rod 51, the second connecting rod 52 and one of the rotating shafts 53.

[0040] The top beam 1, the side guard 2, the first connecting rod 51 and the second connecting rod 52 form a four-bar mechanism. The rotation of the side guard 2 can drive the first connecting rod 51 and the second connecting rod 52 to move, and the detector 4 is connected to the first connecting rod 51, the second connecting rod 52 or one of the rotating shafts 53, so that the detector 4 is set close to the side guard 2; when the side guard 2 is in an extended state, the detector 4 is located directly above the coal mining channel 200, and the detector 4 can directly detect the coal mining channel 200 to obtain the conditions of the coal mining machine drum, coal wall and other areas; when the side guard 2 is in a retracted state, it can drive the first connecting rod 51 and the second connecting rod 52 to move toward the top beam 1, and then drive the detector 4 to move toward the top beam 1, thereby preventing the coal mining machine from colliding with the detector 4 when passing through.

[0041] In some embodiments, the top beam 1 has a base portion 11, the guard rail 2 has a connecting portion 21, the first end of the first connecting rod 51 is rotatably connected to the base portion 11, and the first end of the second connecting rod 52 is rotatably connected to the guard rail 2; the base portion 11, the connecting portion 21, the first connecting rod 51 and the second connecting rod 52 form a parallelogram linkage mechanism.

[0042] Through the above arrangement, the influence of the first connecting rod 51 and the second connecting rod 52 on the guard 2 can be reduced, so that the guard 2 can keep rotating freely, so as to switch freely between the open state and the retracted state.

[0043] like Figures 2 to 5 As shown, the base portion 11 has a first connection point and a second connection point, the connection portion 21 has a third connection point and a fourth connection point, the second connection point is hinged to the third connection point, the first connection point is hinged to the first end of the first connecting rod 51, and the fourth connection point is hinged to the first end of the second connecting rod 52; wherein, the distance between the first connection point and the second connection point is equal to the length of the second connecting rod 52, and the distance between the third connection point and the fourth connection point is equal to the length of the first connecting rod 51, thereby forming a parallelogram linkage mechanism.

[0044] When the guard 2 switches from the open state to the retracted state, it can drive the first connecting rod 51 and the second connecting rod 52 to always move toward the direction close to the top beam 1, and then drive the detector 4 to move toward the direction close to the top beam 1, thereby reducing the risk of collision between the detector 4 and the coal mining machine.

[0045] like Figure 3As shown, when the included angle between the guard 2 and the base 11 reaches the maximum, the guard 2 is in the extreme extension state; Figure 4 As shown, when the angle between the guard 2 and the base 11 is 80° to 100°, the guard 2 is in a normal extended state; Figure 5 As shown, when the included angle between the side guard 2 and the base portion 11 reaches the minimum, the side guard 2 is in a retracted state.

[0046] In some embodiments, Figure 2 As shown, the hydraulic support 100 further includes a suspension seat 6 , which is rotatably connected to the rotating shaft 53 , and the detector 4 is connected to the suspension seat 6 .

[0047] By rotatably connecting the suspension seat 6 with the rotating shaft 53, when the angle between the guard 2 and the top beam 1 changes in the extended state, the suspension seat 6 can always maintain a natural drooping state, and the detector 4 is installed on the suspension seat 6, which can reduce the impact of the angle change between the guard 2 and the top beam 1 on the detector 4, and maintain the detection of the coal mining channel 200 by the detector 4. At the same time, by providing the suspension seat 6 and installing the detector 4 on the suspension seat 6, the installation convenience of the detector 4 can be improved.

[0048] In some embodiments, the hydraulic support 100 further includes a rotating member 61 , which is rotatably connected to the suspension seat 6 , and the detector 4 is connected to the rotating member 61 .

[0049] The detector 4 is installed on the suspension seat 6 through the rotating member 61. The rotating member 61 rotates relative to the suspension seat 6, which can drive the detector 4 to rotate, thereby expanding the detection range and further reducing the detection blind area, so as to simultaneously detect the coal mining machine drum, scraper chute, coal wall and other areas.

[0050] Optionally, the rotating member 61 is a pan / tilt head.

[0051] In some embodiments, the power assembly 3 includes a telescopic member 31, the telescopic member 31 includes a cylinder body 311 and a telescopic rod 312, the cylinder body 311 is rotatably connected to the top beam 1, the telescopic rod 312 is connected to the guardrail 2, and the telescopic rod 312 is slidably connected to the cylinder body 311.

[0052] The telescopic rod 312 slides relative to the cylinder body 311, and can drive the guard 2 to rotate relative to the top beam 1, so that the guard 2 switches between the extended state and the retracted state.

[0053] Optionally, the cylinder body 311 is hinged to the top beam 1 through a first rotating shaft, and the first end of the first connecting rod 51 is also hinged to the base 11 through the first rotating shaft; the power assembly 3 also includes a first rod 32 and a second rod 33, one end of the first rod 32 is hinged to the top beam 1, one end of the second rod 33 is hinged to the guard plate, the other end of the first rod 32 and the other end of the second rod 33 are hinged through the second rotating shaft, and the telescopic rod 312 is also hinged to the second rotating shaft, thereby forming a four-bar linkage between the first rod 32, the second rod 33, the top beam 1, and the guard 2 again, and the telescopic member 31 drives the guard 2 to rotate through the four-bar linkage, which can improve the stability of the guard 2 during rotation, thereby providing a more stable support force for the coal wall.

[0054] In some embodiments, the telescopic member 31 is a hydraulic cylinder.

[0055] The hydraulic cylinder can further improve the stability of the support 2 for the coal wall, so that the position of the support 2 is stable, thereby improving the stability of the position of the detector 4 and improving the detection accuracy.

[0056] In some embodiments, Figure 6 As shown, the rotation axis 53 line of the guard 2 relative to the top beam 1 is the first axis, and the detector 4 and the power assembly 3 are arranged at intervals along the length direction of the first axis.

[0057] By arranging the detector 4 and the power assembly 3 at intervals along the first axis, it is more convenient to arrange the position of the detector 4 and its transmission assembly 5, thereby preventing interference between the transmission assembly 5, the detector 4 and the power assembly 3 during installation or operation.

[0058] Optionally, when two groups of power components 3 are provided on a hydraulic support 100 to drive the guardrail 2 , the detector 4 and the transmission component 5 are located between the two groups of power components 3 .

[0059] In some embodiments, a receiving groove 12 is provided on the top beam 1 , and when the power assembly 3 drives the guardrail 2 to rotate, the detector 4 can be received in the receiving groove 12 .

[0060] When the guard 2 switches to the retracted state, the detector 4 moves to the extreme position in the direction close to the top beam 1. At this time, the detector 4, the first connecting rod 51 and the second connecting rod 52 may collide with the top beam 1. By setting the accommodating groove 12, the detector 4, the first connecting rod 51 and the second connecting rod 52 can be accommodated so that the detector 4 can retract with the guard 2.

[0061] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
