In order to solve the problem that it is inconvenient to adjust the height of the tank with the current conveyor vehicle, the base is first fixed to the frame, and a screw is set on the top of the base to control the lifting of the support plate.

[0025] like Figure 1-Figure 4 As shown, the present embodiment provides a vehicle tank lifting mechanism, including a base 1, positioning holes at both ends of the base 1 for fixing the base 1, a support plate 6 located above the base 1 for supporting the tank body, a slide groove 2 is opened at the middle position of the top of the base 1 along the length direction, and first trapezoidal blocks 3 are slidably arranged at both ends inside the slide groove 2, and a spacing adjustment mechanism 4 is arranged between the two groups of first trapezoidal blocks 3. The inclined surfaces at the tops of the two groups of first trapezoidal blocks 3 are symmetrical to each other, and the bottom ends of the inclined surfaces on the first trapezoidal blocks 3 face the middle position of the slide groove 2, and second trapezoidal blocks 5 are slidably arranged on the tops of the first trapezoidal blocks 3, and the sides of the second trapezoidal blocks 5 are fitted with the inner sides of the slide groove 2, and the top of the second trapezoidal block 5 is fixed on the support plate 6, a reinforcement mechanism for limiting the tank body is arranged between the two ends of the support plate 6, and a limiting mechanism is arranged between the bottom of the support plate 6 and the base 1.

[0026] Overall working principle: During the installation process, the base 1 is first fixed to the frame, and then the tank body is placed on the top of the support plate 6. The arc groove above the support plate 6 can increase the fitting area between the tank body and ensure the supporting stability of the tank body. The support plate 6 is then welded to the tank body, and finally the tank body is reinforced again by the reinforcement mechanism. When the tank body needs to be lifted, the spacing adjustment mechanism 4 is used to control the two groups of first trapezoidal blocks 3 to move toward each other, and the inclined surface of the first trapezoidal block 3 fits with the inclined surface of the second trapezoidal block 5. When the first trapezoidal blocks 3 move toward each other, the second trapezoidal block 5 is pushed upward, thereby lifting the tank body. In addition, when the tank body is lifted, the limiting mechanism is used to ensure that the support plate 6 rises and falls vertically.

[0027] In this embodiment, the spacing adjustment mechanism 4 includes a bidirectional screw 14, a worm wheel 15, a worm 16 and a threaded hole 17. The bidirectional screw 14 is rotatably installed between the two ends inside the slide groove 2. The first trapezoidal block 3 is provided with a threaded hole 17 that cooperates with the bidirectional screw 14. The worm wheel 15 is fixedly installed at the middle position of the bidirectional screw 14, and the worm 16 is meshed with the top of the worm wheel 15.

[0028] Local working principle: When adjusting the spacing between the two groups of first trapezoidal blocks 3, the rotating worm 16 controls the worm wheel 15 to drive the rotation of the bidirectional screw 14. The rotation of the bidirectional screw 14 simultaneously controls the sliding of the two groups of first trapezoidal blocks 3 to adjust the spacing between the first trapezoidal blocks 3. In addition, the self-locking property between the worm wheel 15 and the worm 16 ensures the stability of the adjustment.

[0029] In this embodiment, one end of the worm 16 extends to the outside of the base 1 , and an adjusting wheel is fixed to the end of the worm 16 located outside the base 1 .

[0030] Partial working principle: When controlling the rotation of the worm 16, the rotation of the worm 16 is driven by controlling the rotation of the adjusting wheel, so that the adjustment is more convenient.

[0031] In this embodiment, guide blocks 12 are fixed to the top of the first trapezoidal block 3 along the length direction of the inclined surface, and guide grooves 13 cooperating with the guide blocks 12 are formed at the bottom of the second trapezoidal block 5 .

[0032] Partial working principle: when the second trapezoidal block 5 slides along the inclined surface of the first trapezoidal block 3 , the guide block 12 slides relative to the guide groove 13 , ensuring that the second trapezoidal block 5 moves along the length of the inclined surface of the first trapezoidal block 3 .

[0033] In this embodiment, the cross-sectional shape of the end of the guide block 12 is T-shaped, and the surface of the guide block 12 is provided with a smooth coating.

[0034] Partial working principle: the guide block 12 is limited inside the guide groove 13, ensuring a close fit between the first trapezoidal block 3 and the second trapezoidal block 5.

[0035] In this embodiment, the reinforcement mechanism includes a reinforcement belt 9, a through groove 10 and a positioning bolt 11. The through groove 10 is opened at both ends of the support plate 6. A reinforcement belt 9 is arranged between the insides of the two groups of through grooves 10. A positioning bolt 11 is arranged between the end of the reinforcement belt 9 and the outer side of the support plate 6.

[0036] Local working principle: When the tank body is welded on the support plate 6, the reinforcement belt 9 is attached to the top of the tank body, and both ends pass through the inside of the through groove 10, and then the position of the reinforcement belt 9 is fixed by the positioning bolts 11 to reinforce the tank body.

[0037] In this embodiment, the limiting mechanism includes a sliding hole 7 and a sliding rod 8. The sliding hole 7 is opened at both ends of the bottom of the support plate 6. The sliding rod 8 is vertically slidably installed inside the sliding hole 7, and the bottom end of the sliding rod 8 is fixedly connected to the base 1.

[0038] Partial working principle: while the support plate 6 is raised or lowered, the slide rod 8 slides vertically inside the slide hole 7 to ensure the stability of the lifting of the support plate 6.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
