[0020] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows: The specific structure of this embodiment is as follows: Figure 1-Figure 10As shown, a hydraulic isolation device for coal mine paste filling mining comprises: a base 1, two guide telescopic columns 2 are hingedly connected to the top of the base 1 through a pin shaft, a lower isolation plate 3 is hingedly connected to the top of the base 1 through a pin shaft, a top beam plate 4 is fixedly connected to the top of the two guide telescopic columns 2, an upper isolation plate 5 is hingedly connected to the bottom left of the top beam plate 4 through a pin shaft, the upper isolation plate 5 is slidably connected to the lower isolation plate 3, eight installation slots 6 are opened in the base 1, and four through slots 7 are opened in the base 1; The mounting assembly includes mounting blocks 8 slidably connected to the eight mounting grooves 6, grooves 9 are provided on the front and rear sides of the corresponding mounting blocks 8, elastic telescopic rods 10 are fixedly connected to the two corresponding grooves 9, and the two ends of the two elastic telescopic rods 10 that are far away from each other are fixedly connected to the clamping blocks 11, and the bottoms of the two corresponding clamping blocks 11 are fixedly connected to the fixing rods 12; The design of the block 11 and the fixing rod 12 can effectively protect the electric push rod 18 and other moving components from external impact and wear, thereby extending the service life of the equipment. Due to the adjustability of the mounting components, the device can adapt to different ground conditions, such as uneven or inclined mine bottoms, thereby maintaining the stability and functionality of the device.

[0021] The support assembly includes a support seat 13 fixedly connected to the bottom of the mounting block 8, and a limiting groove 14 is provided in the support seat 13. By setting the limiting groove 14, the limiting groove 14 and the limiting column 15 cooperate with each other to avoid the limiting column 15 from being offset and misaligned, thereby ensuring the stable movement of the limiting column 15; A limiting column 15 is slidably connected through the limiting groove 14, a fixed ball rod 16 is fixedly connected to the bottom end of the limiting column 15, and a support plate 17 is rotatably connected to the fixed ball rod 16; The design of the fixed ball rod 16 and the support plate 17 further enhances the stability of the device, ensuring that reliable supporting force can be maintained under complex working conditions.

The piston rod 27 and the piston cylinder 26 are fixedly connected with the same spring 28. By setting the spring 28, the piston rod 27 can automatically rebound under the action of the elastic force of the spring 28 after being pushed by the second rack 24, thereby avoiding the piston rod 27 from getting stuck and ensuring the stable movement of the piston rod 27. A one-way air inlet is provided on the outside of the piston cylinder 26 , and a fixed nozzle 29 is provided on the top of the piston cylinder 26 .

[0023] By setting up a cleaning component, dust can be cleaned regularly, which helps maintain the good performance of the equipment, extends the service life of the equipment, and reduces potential safety risks caused by equipment wear.

[0024] In some examples, the right side of the lower isolation plate 3 is fixedly connected to a lower isolation jack 30, and the top of the lower isolation jack 30 is fixedly connected to the right side of the upper isolation plate 5; In some examples, a card slot 31 is opened on both sides of the installation slot 6, the card slot 31 is connected to the installation slot 6, the card block 11 is slidably connected in the card slot 31, the shape of the movable block 19 is inclined, and a plurality of one-way air outlets are provided outside the fixed nozzle 29.

[0025] In some examples, the top of the second rack 24 abuts against the bottom of the piston rod 27, the limiting column 15 passes through the corresponding through groove 7, and a moving groove 32 is provided in the support seat 13. By providing the moving groove 32, the second rack 24 can avoid being offset and stuck during the up and down movement, thereby ensuring the stable movement of the second rack 24; The bottom end of the second rack 24 is slidably connected in the movable groove 32, and the guide block 20 is slidably connected in the support seat 13. By setting the guide block 20, the guide block 20 can prevent the movable block 19 from being offset during movement, thereby ensuring the stable movement of the movable block 19.

[0026] In some examples, the first rack 23 and the second rack 24 are respectively meshed on both sides of the same fixed gear 22, and a fixing seat 33 is fixedly connected to the bottom of the base 1. By setting the fixing seat 33, the fixing seat 33 can support the dual-axis motor 34 to avoid shaking and deflection of the dual-axis motor 34 during use, thereby ensuring the stable use of the dual-axis motor 34; A dual-axis motor 34 is fixedly connected inside the fixing seat 33 , and rotating gears 35 are fixedly connected to the front and rear ends of the dual-axis motor 34 . The two rotating gears 35 are rotationally connected to the other two rotating gears 35 through two tracks.

[0027] In some examples, a rubber pad 36 is fixedly connected to the bottom of the support plate 17, and a pressure sensor 37 is clamped inside the rubber pad 36. The signal output end of the pressure sensor 37 is electrically connected to the control signal input end of the electric push rod 18. By setting the pressure sensor 37, it can convert the pressure signal it feels into an electrical signal, and the pressure sensor 37 continuously monitors the pressure of the support point. These data reflect the load borne by the device and the reaction force of the ground. The pressure sensor 37 transmits the monitored pressure data to the control unit through an electrical connection. This control unit can be a built-in controller of the electric push rod 18 or an external main control system. After receiving the pressure data, the control unit will perform intelligent analysis according to a preset program. If it is detected that the pressure exceeds or falls below the safe range, the system will trigger a feedback mechanism. According to the result of the intelligent feedback, the electric push rod 18 will automatically adjust its extension to increase or decrease the support strength. For example, if the pressure sensor 37 detects that the support force is insufficient, the electric push rod 18 will automatically extend to increase the support strength; conversely, if the support force is too large, the electric push rod 18 will automatically shrink to reduce the support strength.

[0028] The working principle of the present invention is: When using the device, firstly, the limiting column 15 is inserted into the corresponding through groove 7, so that the mounting block 8 can drive the support seat 13 to be inserted into the corresponding mounting groove 6, until the two clamping blocks 11 can be inserted into the corresponding clamping groove 31 under the elastic force of the two elastic telescopic rods 10, so that the support seat 13 can drive the fixed ball rod 16, the support plate 17 and the rubber pad 36 to be installed at the bottom of the base 1; Then, the dual-axis motor 34 is started, and the dual-axis motor 34 can drive the two rotating gears 35 to rotate, so that the other two rotating gears 35 can rotate synchronously under the action of the crawler, so that the base 1 can drive the guide telescopic column 2, the top beam plate 4 and the upper isolation plate 5 to move to a suitable position; At this time, the lower isolation jack 30 can be started, and the lower isolation jack 30 can push the upper isolation plate 5 to drive the top beam plate 4 to move upward, while the upper isolation plate 5 can slide upward in the lower isolation plate 3 until the top beam plate 4 fits with the top of the mine cave, and the top beam plate 4 can drive the guide telescopic column 2 to be in a stretched state; Afterwards, the corresponding electric push rod 18 can be started according to the actual situation. The electric push rod 18 can push the moving block 19 to slide horizontally to the right in the inclined groove 21, so that the moving block 19 can drive the guide block 20 to slide to the right in the support seat 13, and the limiting column 15 can drive the fixed gear 22 to slide downward on the rear side of the first rack 23, and drive the second rack 24 to move downward in the moving groove 32, and the moving column drives the fixed ball rod 16, the support plate 17 and the rubber pad 36 to move downward until they are supported on the ground, and the support plate 17 can be rotated and adjusted outside the fixed ball rod 16 according to the flatness of the ground. When the pressure sensor 37 is at a certain threshold, a signal is sent to control the corresponding electric push rod 18 to stop moving; When the device continues to be moved, first restart the electric push rod 18 to push the moving block 19 to slide horizontally to the left in the inclined groove 21, and the moving block 19 can drive the guide block 20 to slide to the left in the support seat 13, so that the limit column 15 can drive the fixed gear 22 to slide upward on the rear side of the first rack 23, and drive the second rack 24 to move upward twice the distance in the moving groove 32, so that the piston rod 27 can be pushed to slide upward in the piston cylinder 26, so that the external air can enter through the one-way air inlet, and under the action of the piston rod 27, it is discharged from the multiple one-way air outlets of the fixed nozzle 29, so that the guide telescopic column 2 and the lower isolation jack 30 can be sprayed out, so that the dust adhering to the outside of the guide telescopic column 2 and the lower isolation jack 30 falls off, and the dust on the base 1 slides off, and the moving column drives the fixed ball rod 16, the support plate 17 and the rubber pad 36 to move upward until they are separated from the ground; Then restart the dual-axis motor 34 so that the base 1 can drive the guide telescopic column 2, the top beam plate 4 and the upper isolation plate 5 to move to a suitable position under the action of the crawler, and then repeat the above movement.

[0029] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
