Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 9 As shown, a cutting box lifting device includes: a base, the base including a bottom frame 1, two vertical frames 2 fixed on the bottom frame 1, and vertical guide rods 3 fixed on the vertical frames 2; a lifting frame 4, the lifting frame 4 being located between the two vertical frames 2, and the lifting frame 4 being movably connected to the vertical guide rods 3 along the height direction; and a moving rod 5, the moving rod 5 being movably connected to the lifting frame 4 along the horizontal direction, and a positioning boss 501 corresponding to the positioning groove 601 of the cutting box 6 being fixed on the moving rod 5, and the number of moving rods 5 being two.

[0022] A mounting plate 202 is fixedly installed on the upper end of the vertical frame 2, adjacent to the end face of another vertical frame 2. The upper end of the vertical guide rod 3 is fixedly connected to the mounting plate 202, and the lower end of the vertical guide rod 3 is fixedly connected to the bottom frame 1. A diagonal brace 201 is fixedly installed on the bottom frame 1. The lower end of the diagonal brace 201 is fixedly connected to the bottom frame, and the upper end of the diagonal brace 201 is fixedly connected to the vertical frame 2. The diagonal brace 201 increases the stability of the base.

[0023] There are four vertical guide rods 3, with two vertical guide rods 3 corresponding to each vertical frame 2; the lifting frame 4 is fixed with guide tubes 401 that match the vertical guide rods 3, and the vertical guide rods 3 are located inside the guide tubes 401; the lifting frame 4 is a frame structure. The guide tubes 401 play a guiding role in the movement of the moving frame, making the movement of the moving frame more stable.

[0024] The two ends of the movable rod 5 are fixed with sliding rods 502; the lifting frame 4 is fixed with a column 403 corresponding to the sliding rod 502, and the column 403 is fixed with a sleeve 402 matching the sliding rod 502. The sliding rod 502 is movably connected to the inside of the sleeve 402.

[0025] The slide rod 502 has a first limiting hole 503, and the sleeve 402 has a second limiting hole 405 corresponding to the first limiting hole 503. The limiting pin (not shown in the figure) is detachably inserted through the first limiting hole 503 and the second limiting hole 405. When the two moving rods 5 move towards each other and the positioning boss 501 is inserted into the positioning groove 601, the limiting pin is inserted through the first limiting hole 503 and the second limiting hole 405 in sequence to limit the rod.

[0026] One of the movable rods 5 has a chamfered edge at one end of its insertion rod adjacent to the other movable rod 5; the other movable rod 5 has a corresponding receiving tube fixed on its insertion rod. The chamfered structure of the insertion rod of one of the movable rods 5 facilitates the insertion rod to be inserted into the inside of the receiving tube. The setting of the receiving tube makes the structure between the two movable rods 5 more stable and reduces the possibility of bending of the insertion rod.

[0027] Two sleeves 402 on the same side are fixedly connected by a connecting crossbar 404. A clamping hydraulic cylinder 7 is fixedly mounted on the connecting crossbar 404. The housing of the clamping hydraulic cylinder 7 is fixedly connected to the connecting crossbar 404. The output shaft of the clamping hydraulic cylinder 7 is fixedly connected to the moving rod 5. The clamping hydraulic cylinder 7 is used to drive the moving rod 5 to move, so that the two moving rods 5 move towards each other or in opposite directions.

[0028] The base is fixed with a drive assembly 8 for moving the lifting frame 4.

[0029] In some embodiments, the drive component 8 is a lifting hydraulic cylinder, the output shaft of which is connected to the lifting frame 4, and the housing of the lifting hydraulic cylinder is fixedly connected to the bottom frame 1. The stroke of the output shaft of the lifting hydraulic cylinder is greater than the length of a single section of the cutting box 6.

[0030] In other embodiments, such as Figure 9As shown, the drive assembly 8 includes a first multi-stage hydraulic cylinder 803, a U-shaped pad 801, and a second multi-stage hydraulic cylinder 804. An ear plate 802 is fixedly mounted on the upper end of the vertical rod of the U-shaped pad 801. The housing of the first multi-stage hydraulic cylinder 803 is fixedly connected to the bottom frame 1, and the output shaft of the first multi-stage hydraulic cylinder 803 is fixedly connected to the ear plate 802. The housing of the second multi-stage hydraulic cylinder 804 is fixedly connected to the upper end face of the horizontal rod of the U-shaped pad 801, and the output shaft of the second multi-stage hydraulic cylinder 804 is fixedly connected to the lifting frame 4. The sum of the strokes of the output shafts of the first multi-stage hydraulic cylinder 803 and the second multi-stage hydraulic cylinder 804 is greater than the length of a single section of the cutting box 6. By setting the first multi-stage hydraulic cylinder 803, the U-shaped pad 801, and the second multi-stage hydraulic cylinder 804, the height of the drive assembly 8 is reduced.

[0031] Work process: In this implementation, the movable frame is located at the bottom. The cutting box 6 passes through the bottom frame 1 and the movable frame in sequence. The clamping hydraulic cylinder 7 drives the two moving rods 5 to move. The positioning boss 501 of the moving rod 5 is inserted into the positioning groove 601 of the cutting box 6. Then, the insertion rod is limited by the limit pin. The drive assembly 8 drives the lifting frame 4 to move upward. After moving the length of a single section of the cutting box 6, the uppermost cutting box 6 is hoisted by a crane (or temporarily fixed by a forklift). Then, the limit pin is pulled out, the output shaft of the clamping hydraulic cylinder 7 retracts the moving rod 5 to reset, and then the drive assembly 8 drives the lifting plate to move downward. The positioning boss 501 is aligned with the positioning groove 601 of the next section of the cutting box 6. The positioning boss 501 of the moving rod 5 is inserted into the positioning groove 601 of the cutting box 6. Then, the insertion rod is limited by the limit pin. The uppermost cutting box 6 is disassembled. The disassembled cutting box 6 is moved to the designated position between the two vertical frames 2.

[0032] Compared to traditional crane lifting, the positioning boss 501 of the moving rod 5 can fix the lower cutting box 6 during the disassembly of the cutting box 6, and the up and down movement of the lifting frame 4 is more stable than the lifting by the crane, which improves the stability of the construction process.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
