[0016] A device for adjusting a separation platform of a feeding trolley of a grinding mill comprises a grinding mill cylinder 1, a feeding trolley 2, a track wheel 4, a feeding trolley movable track 5, a hydraulic cylinder 9, a supporting slide block 11, a rear hydraulic jack 12, a front hydraulic jack 14, a steel beam frame 16 and a hydraulic station 17. The feeding trolley movable track 5 is welded to the steel beam frame 16, the track wheel 4 is installed at the bottom of the feeding trolley 2, the feeding trolley 2 is movably arranged on the feeding trolley movable track 5 through the track wheel 4, and the feeding trolley movable track 5 is welded to the steel beam frame 16. The two ends of the steel beam frame 16 are respectively hingedly connected to the rear end hydraulic jack 12 and the front end hydraulic jack 14 through the pin 1 6 and the pin 4 13; the steel beam frame 16 is overlapped on the support slider 11, and the support slider 11 is hingedly connected to the hydraulic cylinder 9 through the pin 3 10; the support slider 11, the rear end hydraulic jack 12 and the front end hydraulic jack 14 are installed under the movable track 5 of the feeding trolley, the hydraulic cylinder 9 is connected to the support slider 11, and the hydraulic station 17 is respectively connected to the hydraulic cylinder 9, the rear end hydraulic jack 12 and the front end hydraulic jack 14.
[0017] The rear end hydraulic jack 12 and the front end hydraulic jack 14 adjust the inclination angle range of the movable track 5 of the feeding trolley to ±10°.
[0018] The hydraulic station 17 is connected to the hydraulic cylinder 9, the rear hydraulic jack 12 and the front hydraulic jack 14 respectively through hydraulic oil pipes.
[0019] The number of the rear end hydraulic jacks 12 is two, the number of the front end hydraulic jacks 14 is two, the number of the supporting slide blocks 11 is four, and the number of the hydraulic cylinders 9 is four.
[0020] It also includes a front fixed rail 3 and a rear fixed rail 7, and the front fixed rail 3 and the rear fixed rail 7 are fixed on the ground.
[0021] In actual application, when the feeding trolley 2 needs to move, the rear end hydraulic jack 12 and the front end hydraulic jack 14 are adjusted by controlling the hydraulic station 17 so that the feeding trolley movable track 5 has a certain inclination angle. Then, the feeding trolley 2 relies on its own weight to make the track wheel 4 overcome the friction force and roll on the trolley movable track 5. The feeding trolley movable track 5 is laid with rails and fixed on the steel beam frame 16.
[0022] The movable track 5 of the feeding trolley is welded on the steel beam frame 16, and is integrally connected to the rear hydraulic jack 12 and the front hydraulic jack 14 through a pin 1 6 and a pin 4 13.
[0023] When the feeding trolley 2 is working in the mill cylinder 1, it relies on the supporting slider 11 as a support body for supporting the steel beam frame 16 and the feeding trolley movable track 5. The supporting slider 11 is composed of four sliders of the same size. The supporting sliders 11 are of consistent height to ensure that the horizontal plane of the feeding trolley 2 is level; when the feeding trolley 2 needs to move, the hydraulic station 17 controls the hydraulic cylinder 9 to pull the supporting slider 11 out of the space under the feeding trolley movable track 5.
[0024] The support slide block 11 is hingedly connected to the hydraulic cylinder 9 via a pin shaft 3 10 .
[0025] The hydraulic station 17 is connected to the hydraulic cylinder 9, the rear hydraulic jack 12 and the front hydraulic jack 14 respectively through hydraulic oil pipes.
[0026] The rear hydraulic jack 12 and the front hydraulic jack 14 are adjusted so that the inclination angle range of the movable track 5 of the feeding trolley is ±10°.
[0027] The working process of the utility model is as follows:
[0028] When the feeding trolley 2 needs to be pulled out, the hydraulic station 17 is first started to control the front hydraulic jack 14 and the rear hydraulic jack 12 to extend upward until the feeding trolley movable track 5 and the steel beam frame 16 are separated from the support slide 11, and then the hydraulic cylinder 9 is controlled to move to pull the support slide 11 out to the space below the feeding trolley movable track 5 until the feeding trolley 2 is pulled out. Figure 1 As shown in the figure, the support slider moves to the rear position 15, freeing up space for the feeder trolley movable track 5 to move up and down, and then the front hydraulic jack 14 and the rear hydraulic jack 12 are simultaneously controlled to retract downward. The downward displacement of the front hydraulic jack 14 is smaller than the downward displacement of the rear hydraulic jack 12, so that the feeder trolley movable track 5 forms the following Figure 3 As shown in the figure, the adjustable range of the inclination angle is -10°<θ<10°. At this time, the feeding trolley 2 will slowly move out of the mill cylinder 1 to a suitable position in the direction indicated by the arrow, and then adjust the front hydraulic jack 14 and the rear hydraulic jack 12 to make the inclination angle of the feed trolley movable track 5 0°. At this point, the feeding trolley 2 is pulled out completely.
[0029] When the feeding trolley 2 needs to return to its original position, the hydraulic station 17 is first started, and the front hydraulic jack 14 and the rear hydraulic jack 12 are simultaneously controlled to extend upward. The extension displacement of the front hydraulic jack 14 is smaller than the extension displacement of the rear hydraulic jack 12, so that the movable track 5 of the feeding trolley is formed as follows. Figure 4 The tilt angle shown, the tilt angle can be adjusted within a range of -10°
