It is widely used in many different fields and can cut objects and better cut and crush collected rocks, which is beneficial for subsequent rock experimental testing.

[0003] An existing patent (publication number: CN116165080B) discloses a high-pressure water jet rock crushing experimental device, comprising an operating table and a water spray head. A heating mechanism is provided at the upper end of the operating table, and a pressurizing mechanism is provided at the upper end of the operating table near the front side of the heating mechanism. The heating mechanism comprises a support frame fixedly provided at the upper end of the operating table, a hydraulic cylinder is fixedly provided at one end of the support frame, a connecting plate is fixedly provided at the other end of the hydraulic cylinder, a toothed plate is fixedly provided at the lower end of the connecting plate, a gear plate is meshed with the lower end of the toothed plate, a transmission shaft is fixedly provided on the inner side of the gear plate, and a movable frame is movably provided on the outer side of the transmission shaft. The high-pressure water jet rock crushing experimental device described in the present invention facilitates heating and pressurizing of rocks through the mutual cooperation between the heating mechanism and the pressurizing mechanism, greatly improves the efficiency of heating, and effectively controls pressurization. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: 1.

When clamping, the surface fitting heating pad can directly fit on the surface of the rock. During the fitting process, the fitting heating pad will be affected by the connected round ball.

[0018] In the present invention, the rock is placed above the heating plate and driven by the two-way transmission mechanism to clamp and fix the rock, which can be clamped more quickly. When the movable component fits the rock, the connected second connecting rod causes the concave plate to slide back and forth inside the sliding bin through the resistance of the rock, and the clamping resistance of the three movable components is evenly distributed, making the clamping more secure. Two clamping mechanisms are used at the same time. When clamping rocks of different sizes, the clamping mechanism can be connected by the stabilizing mechanism so that when the guide column is pushed, the two-way telescopic column below retracts, and cooperates with the connected center column to rotate the long plate, so that the force of the upper and lower clamping mechanisms is distributed, making the clamping and fixation of the rock more stable and secure.

[0043] In this embodiment, Figure 3 and Figure 4 As shown, the bidirectional telescopic column 63 is composed of two spring cylinders connected back to back.

[0044] The use method and advantages of the present invention: The use method of the high-pressure water jet rock crushing experimental device, the working process is as follows:

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown: the operator holds the rock and places it above the heating plate 8, and then drives the transmission motor 31 to rotate, so that the outer ring gear of the connected gear plate 32 rotates and forms a meshing connection with the tooth groove below the tooth groove plate 33, driving the tooth groove plates 33 on both sides to move horizontally relative to each other, and at the same time driving the two mobile bins 41 fixed on the front of the tooth groove plate 33 to move relative to the middle, and in the process of movement, the clamping mechanism 5 inside the mobile bin 41 clamps and fixes the rock, so that the fitting heating pad 555 fits on the surface of the rock, and the round ball 553 rotates inside the semicircular plate 552, ensuring the fitting degree of the fitting heating pad 555 and the rock surface, thereby ensuring the uniformity of heating the rock by the fitting heating pad 555;

[0046] At the same time, during the clamping process, after the middle fitting heating pad 555 contacts the rock surface, as the two movable chambers 41 move relative to each other, the two side blocks 52 in the middle slide on the inner wall of the sliding chamber 51, thereby making the two side fitting heating pads 555 fit the rock surface, ensuring that each fitting heating pad 555 exerts the same pressure on the rock surface;

[0047] When clamping the conical rock, the lower sliding bin 51 first contacts the bottom of the rock, so that the lower sliding bin 51 is first subjected to the resistance force. When the lower sliding bin 51 is subjected to the clamping resistance, the lower sliding bin 51 slides toward the inside of the moving bin 41, so that the two-way telescopic column 63 drives the long plate 64 to deflect and pushes the upper square column plate 61 to slide toward the outside of the moving bin 41, thereby causing the upper square column plate 61 to contact the upper side of the conical rock. When the fitting heating pads 555 on the two sliding bins 51 are both in contact with the surface of the rock, the two moving bins 41 continue to move relative to each other so that the fitting heating pads 555 on the two sliding bins 51 are both in contact with the surface of the rock, thereby ensuring the stability of the device in clamping the rock, and ensuring that the two sliding bins 51 on the same side exert balanced pressure on the upper and lower sides of the rock, thereby ensuring the efficiency of the device in heating the rock.

[0048] After the clamping and heating is completed, the transmission motor 31 is driven to rotate in the opposite direction, so that the tooth plate 33 drives the mobile bin 41 to move back, and at the same time drives the engaging column 45 under the mobile bin 41 to move back. The depth of the internal connecting groove of the arc groove 73 opened on the side of the lower adjusting column 71 is lower than that of the inside of the transverse groove 72, so that the spring column 46 moves inside the arc groove 73, driving the adjusting column 71 to rotate half a circle, so that the outer ring gear of the connected bevel gear 75 drives the bevel gear placed under the heating plate 8 to rotate ninety degrees, and at the same time rotates the heated rock ninety degrees, and then drives the transmission motor 31 to rotate forward again, repeats the clamping steps, clamps and heats the rotated rock, and then transports and installs the water pipe through the pipe above the spray gun 12, and starts the spray gun 12 to perform a rock crushing experimental operation.
