DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0021] Embodiment one, please refer to Figures 1-6 A metal lining plate wear-resistant testing device and method for new material application, comprising: The lining plate detection bin 100 is internally fitted with an electric telescopic rod 200, and the telescopic end of the electric telescopic rod 200 is rotationally connected with a rotating block 300; The electric polishing wheel 400 is fitted at the bottom of the rotating block 300, and the lining plate detection bin 100 is internally fitted with a lining plate placement table 500; The outer side of the rotating block 300 is fitted with a hydraulic bin one 601, the inner side of the lining plate detection bin 100 is fitted with a hydraulic bin three 609, and a transmission member for transmission is fitted between the hydraulic bin one 601 and the hydraulic bin three 609. The transmission member comprises a spring one 602 fitted in the inner side of the hydraulic bin one 601, the inner side of the hydraulic bin one 601 is slidably connected with a sliding block 603 through a piston, one end of the spring one 602 away from the inner wall of the hydraulic bin one 601 is fitted at the side position of the sliding block 603, and one end of the hydraulic bin one 601 away from the spring one 602 is slidably connected with a transmission rod one 604 through a piston. Open the lining plate detection bin 100, place the metal lining plate on the lining plate placement table 500, start the electric telescopic rod 200, drive the electric polishing wheel 400 connected with the electric telescopic rod 200 through the rotating block 300 to move to the metal lining plate, start the electric polishing wheel 400, and perform corresponding wear-resistant testing operation on the metal lining plate for new material application. At this time, the rapidly rotating electric polishing wheel 400 drives the rotating block 300 located at the top thereof to rotate, so that the rotating block 300 drives the hydraulic bin one 601 fitted on the outer side thereof to rotate rapidly. The sliding block 603 located in the hydraulic bin one 601 and slidably connected with the hydraulic bin one 601 through a piston is stretched under the action of centrifugal force, and moves along the inner side of the hydraulic bin one 601. With the movement of the sliding block 603, the oil originally stored in the hydraulic bin one 601 can be pushed, so that the oil flows to the side close to the transmission rod one 604, and drives the transmission rod one 604 slidably connected with the hydraulic bin one 601 through a piston to stretch out from the hydraulic bin one 601.

[0022] The telescopic end side of the electric telescopic rod 200 is equipped with a hydraulic bin two 605, which is close to one side of the transmission rod one 604 and is connected with a force rod one 606 through a piston sliding. The force rod one 606 is located at the side of the transmission rod one 604 and is in contact with the transmission rod one 604. The side of the force rod one 606 is equipped with a spring two 607. The side of the hydraulic bin two 605 away from the transmission rod one 604 is equipped with a hydraulic hose 608 in communication therewith. When the transmission rod one 604 rotates synchronously with the hydraulic bin one 601 to extend, the force rod one 606 located at the side thereof is extruded, so that the force rod one 606 slides into the hydraulic bin two 605 connected with the piston. With the movement of the force rod one 606, the oil originally stored in the hydraulic bin two 605 is extruded, and part of the oil flows into the hydraulic hose 608 in communication therewith, so that part of the oil in the hydraulic hose 608 flows into the hydraulic bin three 609 in communication therewith.

[0023] The side of the hydraulic bin three 609 is connected with a transmission rod two 610 through a piston sliding. The side of the transmission rod two 610 is equipped with a support rod 611. When part of the oil in the hydraulic hose 608 flows into the hydraulic bin three 609 in communication therewith, the oil originally stored in the hydraulic bin three 609 flows to the side close to the transmission rod two 610, drives the transmission rod two 610 connected with the hydraulic bin three 609 through a piston sliding to move out of the hydraulic bin three 609, so that the transmission rod two 610 drives the support rod 611 equipped on the side thereof to move, supports the metal lining plate in the lining plate placing table 500 and with small shape, prevents the metal lining plate from being slightly deformed, and improves the accuracy of the device for the wear test result of the metal lining plate.

[0024] After the detection operation is completed, the electric polishing wheel 400 stops rotating, the hydraulic bin one 601 stops rotating, the sliding block 603 loses the effect of centrifugal force, and can be reset under the action of the spring one 602. Similarly, the transmission rod one 604 is reset, the force rod one 606 loses the action of the transmission rod one 604, and can be reset under the action of the spring two 607. Similarly, the support rod 611 is reset.

[0025] In use, open the lining detection bin 100, place the metal lining on the lining placement table 500, start the electric telescopic rod 200, drive the electric polishing wheel 400 connected with the electric telescopic rod 200 through the rotating block 300 to move to the metal lining, start the electric polishing wheel 400, and perform the corresponding wear-resistant test operation on the metal lining applied to the new material. At this time, the rapidly rotating electric polishing wheel 400 drives the rotating block 300 located on the top thereof to rotate, so that the rotating block 300 drives the hydraulic bin one 601 assembled on the outer side thereof to rotate rapidly. The sliding block 603 located in the hydraulic bin one 601 and connected with the hydraulic bin one 601 through the setting piston sliding connection is stretched under the action of centrifugal force, and the spring one 602 is stretched and moves along the inside of the hydraulic bin one 601. With the movement of the sliding block 603, the oil originally stored in the hydraulic bin one 601 can be pushed, so that the oil flows to the side close to the transmission rod one 604, and the transmission rod one 604 connected with the hydraulic bin one 601 through the setting piston sliding connection is driven to stretch out of the hydraulic bin one 601. The transmission rod one 604 rotating with the hydraulic bin one 601 is stretched out synchronously, thereby extruding the stress rod one 606 located on the side surface, so that the stress rod one 606 slides into the hydraulic bin two 605 connected with it through the setting piston sliding connection. With the movement of the stress rod one 606, the oil originally stored in the hydraulic bin two 605 can be extruded, part of the oil flows into the hydraulic hose 608 connected therewith, so that part of the oil in the hydraulic hose 608 flows into the hydraulic bin three 609 connected therewith. The oil originally stored in the hydraulic bin three 609 flows to the side close to the transmission rod two 610, drives the transmission rod two 610 connected with the hydraulic bin three 609 through the setting piston sliding connection to move out of the hydraulic bin three 609, so that the transmission rod two 610 drives the support rod 611 assembled on the side surface to move, and supports the metal lining with small size in the lining placement table 500. After the detection operation is completed, when the electric polishing wheel 400 stops rotating, the hydraulic bin one 601 stops rotating, the sliding block 603 loses the action of centrifugal force, and can be reset under the action of the spring one 602. Similarly, the transmission rod one 604 is reset, the stress rod one 606 loses the action of the transmission rod one 604, and can be reset under the action of the spring two 607. Similarly, the support rod 611 is reset.

[0026] Example two, please refer to Figures 1-8Based on Embodiment 1, the interior of the liner inspection chamber 100 is equipped with an auxiliary support assembly 700 for supporting the metal liner. The auxiliary support assembly 700 includes a transmission rod 701 mounted at the bottom of transmission rod 2 610. A rotating rod 702 is rotatably connected to the side of the liner placement platform 500. Connecting rod 1 703 and connecting rod 2 704 are fixedly connected to the outer side of the rotating rod 702. Connecting rod 1 703 is located at the top of transmission rod 3 701 and is hinged to it. When transmission rod 2 610 moves the support rod 611 towards the side of the metal liner, transmission rod 2 610 simultaneously moves transmission rod 3 701 mounted at its bottom, causing transmission rod 3 701 to move the connecting rod 1 703 hinged to it. Figure 7 and Figure 8 As shown, the movement of the connecting rod 703 causes the rotating rod 702, which is fixedly connected to it, to rotate clockwise at a certain angle.

[0027] A through-type transmission rod 705 is slidably connected inside the liner placement platform 500. The transmission rod 705 is located at the top of the connecting rod 704 and is hinged to the connecting rod 704. An auxiliary support rod 706 is mounted on the side of the transmission rod 705. When the rotating rod 702 rotates clockwise at a certain angle, it causes the connecting rod 702 to rotate clockwise at a certain angle. The connecting rod 704 then causes the transmission rod 705, which is hinged to it, to move a certain distance in the horizontal direction. This causes the transmission rod 705 to move the auxiliary support rod 706, providing auxiliary support to the other side of the metal liner and further improving the support effect of the device on the metal liner.

[0028] Similarly, after the transmission rod 610 and the support rod 611 have completed their reset, the auxiliary support rod 706 will also be reset.

[0029] In use, based on Embodiment 1, when transmission rod 2 610 drives support rod 611 to move towards the side of the metal liner, transmission rod 2 610 simultaneously drives transmission rod 3 701, which is mounted at its bottom, to move. This causes transmission rod 3 701 to drive connecting rod 1 703, which is hinged to it, to move. Figure 7 and Figure 8 As shown, the movement of connecting rod 703 causes the rotating rod 702, which is fixedly connected to it, to rotate clockwise at a certain angle. This causes the rotating rod 702 to cause the connecting rod 704, which is fixedly connected to it, to rotate clockwise at a certain angle. The connecting rod 704 then causes the transmission rod 705, which is hinged to it, to move a certain distance in the horizontal direction. This causes the transmission rod 705 to move the auxiliary support rod 706 to provide auxiliary support for the other side of the metal liner. Similarly, when the transmission rod 610 and the support rod 611 have completed their reset, the auxiliary support rod 706 also resets.

[0030] Example 3, please refer to Figures 1-10 Based on Embodiments 1 and 2, the liner detection chamber 100 is equipped with an auxiliary extraction component 800 for extracting debris. The auxiliary extraction component 800 includes an extraction pipe 801 installed inside the liner detection chamber 100 and connected to an air pump. A hydraulic chamber 4 802 is installed on the side of the hydraulic chamber 3 609 and communicates with it. An arc-shaped rod 803 is slidably connected to the end of the hydraulic chamber 4 802 away from the hydraulic chamber 3 609 via a piston. When the detection operation causes the oil in the hydraulic chamber 3 609 to flow, some of the oil flows into the hydraulic chamber 4 802, which is connected to the hydraulic chamber 3 609. This causes the oil originally stored in the hydraulic chamber 4 802 to flow towards the side closer to the arc-shaped rod 803, and the arc-shaped rod 803 extends out from the hydraulic chamber 4 802.

[0031] A connecting shaft 804 is rotatably connected to the top of the extraction pipe 801. The connecting shaft 804 is located on the side of the arc-shaped rod 803 and is fixed to the arc-shaped rod 803. A block 805 is fitted to the bottom of the connecting shaft 804. When the arc-shaped rod 803 extends out of the hydraulic chamber 802, it drives the connecting shaft 804, which is rotatably connected to the extraction pipe 801 and fixedly connected to the arc-shaped rod 803, to rotate. The connecting shaft 804 drives the block 805, which is fixedly connected to it, to rotate, opening the extraction pipe 801, which was originally closed by the block 805. At this time, the debris generated during the test can be extracted by the air pump and the extraction pipe 801. When the liner test chamber 100 is flushed with water, the extraction pipe 801 is closed by the block 805 to prevent water from entering the air pump through the extraction pipe 801, thus improving the protection effect of the device in this situation and making the device easier to use.

[0032] In use, based on Embodiment 1 and Embodiment 2, when the oil in hydraulic chamber 3 609 is flowed due to the detection operation, some of the oil flows into hydraulic chamber 4 802, which is connected to hydraulic chamber 3 609. This causes the oil originally stored in hydraulic chamber 4 802 to flow towards the side closer to the arc rod 803. The arc rod 803 then extends out of hydraulic chamber 4 802. As the arc rod 803 extends, it drives the connecting shaft 804, which is rotatably connected to the extraction pipe 801 and fixedly connected to the arc rod 803, to rotate. The connecting shaft 804 drives the block 805, which is fixedly connected to it, to rotate, opening the extraction pipe 801, which was originally closed by the block 805. At this time, the debris generated during the detection can be extracted through the air pump and the extraction pipe 801. When the liner detection chamber 100 is flushed with water, the extraction pipe 801 is closed by the block 805 to prevent water from entering the air pump through the extraction pipe 801.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
