[0020] Due to the drawing angle problem, some components may not be drawn, but their positions and connection relationships can be understood according to the text description part.
[0021] As Figure 1 - Figure 2 As shown, the present utility model is a mortise and tenon type frame structure of a high-pressure discharging machine, including a cross beam 1, and the cross beam 1 is connected to a lifting frame 6 through bolts and a first mortise and tenon mechanism.
[0022] The bottom of the lifting frame 6 is a lifting bottom pipe 16, and both sides of the lifting bottom pipe 16 are connected to a lifting vertical pipe 8 through a second mortise and tenon mechanism and a reinforcing rib 15. The second mortise and tenon mechanism includes a cross plate 7, and the cross plate 7 is horizontally installed in the lifting bottom pipe 16. Both ends of the cross plate 7 extend out of the lifting bottom pipe 16 and pass through the lifting vertical pipe 8. Specifically, both ends of the lifting bottom pipe 16 are closely attached to the inner side of the lower part of the lifting vertical pipe 8. The cross plate 7 is plug welded in the lifting bottom pipe 16, the reinforcing plate 9 is plug welded in the lifting vertical pipe 8, and a notch is opened in the lifting vertical pipe 8. The cross plate 7 is inserted into the notch of the lifting vertical pipe 8 to realize the mortise and tenon type connection between the lifting vertical pipe 8 and the lifting bottom pipe 16. Finally, each connection part is welded to realize secondary strengthening and fastening.
[0023] The reinforcing rib 15 is an L-shaped structure and is welded at the junction of the lifting bottom pipe 16 and the lifting vertical pipe 8. A support plate 14 is installed on the reinforcing rib 15, and the reinforcing rib 15 improves the connection strength between the lifting bottom pipe 16 and the lifting vertical pipe 8.
[0024] As Figure 3 As shown, a jack hole 8-1 runs horizontally through the upper part of the lifting vertical pipe 8, and a flange 24 sleeved on the lifting vertical pipe 8 is arranged below the jack hole 8-1.
[0025] As Figure 4As shown in the figure, the bottom of the cross beam 1 is a beam slab 23, and lifting connection holes 1-1 are symmetrically arranged on the beam slab 23. The upper part of the lifting vertical pipe 8 passes through the lifting connection hole 1-1 and extends into the cross beam 1 until the flange 24 abuts against the beam slab 23. Lifting connection holes 1-2 are evenly distributed on the outer periphery of the lifting connection hole 1-1, and through holes adapted thereto are provided on the flange 24. The beam slab 23 and the flange 24 are connected by high-strength bolts 2, and spring washers 3 and hex nuts 4 are sleeved on the high-strength bolts 2. Due to the high-pressure working condition, double hex nuts 4 are used for tightening. The specification of the high-strength bolt 2 is grade 12.9.
[0026] The first tenon and mortise mechanism includes a dowel plate 20. A fixed inclined plate 19 and a dowel plate 20 are arranged in the jacking hole 8-1. The fixed inclined plate 19 and the dowel plate 20 are respectively fixedly connected to the lifting vertical pipe 8 and the beam slab 23. The contact surfaces of the fixed inclined plate 19 and the dowel plate 20 are inclined surfaces, and the angle of the inclined surface is 3°.
[0027] Specifically, the dowel plate 20 is inserted between the cross beam 1 and the lifting frame 6 and locked, so that the upper surface of the dowel plate 20 with a taper of 3° is closely attached to the inside of the square pipe of the lifting frame 6, realizing the secondary fastening of the tenon and mortise connection between the cross beam 1 and the lifting frame 6; after locking, a mounting hole for an internal hexagon socket head cap screw 21 is drilled on the cross beam 1, and the dowel plate 20 and the cross beam 1 are fastened with the internal hexagon socket head cap screw 21.
[0028] The key joints of the entire frame structure adopt tenon and mortise structures, enabling the components of the frame to be closely connected even without the action of bolts and welds, providing safety guarantees.
[0029] The working process of the present utility model is as follows:
[0030] A hydraulic cylinder 10 is fixedly installed in the cross beam 1 through bolts. The piston end of the hydraulic cylinder 10 is vertically downward and a pressure plate 11 is installed. The container 12 is placed on the support plate 14 and the support bracket 13. When the pressure plate 11 presses down, it will generate a huge downward pressure on the container 12 and act on the support plate 14 and the support bracket 13 of the lifting frame 6, and will also generate the same reaction force on the cross beam 1. The support bracket 13 is installed on the lifting bottom pipe 16.
[0031] The baffle plate 8 is welded to the lifting vertical pipe 8, and the sealing plate 17 is welded to the lifting vertical pipe 8, which can reduce the force deformation of the lifting vertical pipe 8. The beam plate 23 of the cross beam 1 and the flange 24 of the lifting frame 6 are connected by high-strength bolts 2 and hexagon nuts 5. The pin plate 20 is inserted from the notch of the side plate 22 into the space between the fixed inclined plate 19 and the beam plate 23. The fixed inclined plate 19 is welded to the lifting vertical pipe 8 to increase the contact area with the pin plate 20 and reduce the extrusion stress. The pin plate 20 is fixed to the beam plate 23 with internal hexagon socket head cap screws 21, which can ensure the close contact between the pin plate 20 and the fixed inclined plate 19 when the equipment vibrates. The contact surface between the pin plate 20 and the fixed inclined plate 19 is a 3° conical surface, which can achieve self-locking under the downward pressure to prevent the pin plate 20 from popping out. Even when the bolts are loosened and fallen off, due to the function of the pin plate 20, the cross beam 1 and the lifting frame 6 will not be separated.
[0032] It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
