[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] like Figure 1-2As shown, a mast-type aerial work platform includes a traveling vehicle body 1 and a mast 2 located on top of the traveling vehicle body 1. A standing platform 3 is located at the upper end of the mast 2. The mast 2 is located on top of the traveling vehicle body 1, and the standing platform 3 is located at the upper end of the mast 2. Workers work on the standing platform 3. An installation cylinder 4 is provided on the side wall of the standing platform 3, passing downward through the standing platform 3 and extending to the bottom of the standing platform 3. The installation cylinder 4 is fixed to the side wall of the standing platform 3 and can be welded to the standing platform 3 to form an integral structure, thereby strengthening the structural strength. The upper part of the installation cylinder 4 is located on the side wall of the standing platform 3 and is closed. The top of the installation cylinder 4 is closed, forming a support structure for the mast 2. The lower part of the installation cylinder 4 is located below the standing platform 3 and is open. The installation cylinder 4 is sleeved on the upper end of the mast 2. The opening of the installation cylinder 4 protrudes from the bottom of the standing platform 3 to facilitate sleeved on the upper end of the mast 2 and connected to the upper end of the mast 2, so that the mast 2 can be raised and lowered. The lifting and lowering action of the standing platform 3 is driven. The mounting cylinder 4 is sleeved on the upper end of the mast 2, forming a split structure, which can realize the quick separation and installation between the mounting cylinder 4 and the mast 2. The lower outer edge of the mounting cylinder 4 is provided with a first mounting plate 41. The outer wall of the mast 2 is provided with a second mounting plate 21 that cooperates with the first mounting plate 41 and is connected by bolts. The outer edge of the lower opening of the first mounting plate 4 can be connected to the mounting cylinder 4 by welding. The second mounting plate 21 can be connected to the outer wall of the mast 2 by welding. The mounting cylinder 4 and the mast 2 are connected by the first mounting plate 41 and the second mounting plate 21 and fixed by bolts. This can enhance the reliability of the structural connection and can quickly disassemble and assemble the standing platform 3 and the mast 2 while ensuring that the standing platform 3 and the mast 2 are intact, so as to facilitate the reuse of the mast 2 and the standing platform 3 and facilitate the replacement of the standing platform 3.

[0015] like Figure 2As shown, the mast 2 includes a support portion 22 located outside the mounting cylinder 4 and a connecting portion 23 located on the top of the support portion 22 and inside the mounting cylinder 4. The support portion 22 and the connecting portion 23 are integrally formed. The mounting cylinder 4 is sleeved around the support portion 22 and forms a connection structure with the mast 2. A second mounting plate 21 is located at the top edge of the support portion 22, which can limit the installation of the mounting cylinder 4 and ensure that the mounting cylinder 4 can be quickly installed into place. A gap 40 is provided between the outer wall of the connecting portion 23 and the inner wall of the mounting cylinder 4. The gap 40 can reduce wear and noise during installation or disassembly of the connecting portion 23 and the mounting cylinder 4, and improve installation efficiency. Multiple axially oriented... A strip slide rail 231 protruding from the gap 40 is provided. A strip slider 42 protruding from the gap 40 is provided on the inner wall of the mounting cylinder 4, which slides with the strip slide rail 231. The strip slide rail 231 on the outer wall of the connecting part 23 and the strip slider 42 on the inner wall of the mounting cylinder 4 form a sliding fit within the gap 40, which provides radial support for the connecting part 23 and the mounting cylinder 4, enhances the structural stability between the connecting part 23 and the mounting cylinder 4, avoids relative displacement between the connecting part 23 and the mounting cylinder 4 which would affect the installation efficiency, and improves the smoothness of the connecting part 23 and the mounting cylinder 4 during disassembly and assembly, ensuring quick disassembly and assembly between the connecting part 23 and the mounting cylinder 4, so as to facilitate the replacement of the standing platform 3.

[0016] like Figure 2-3As shown, the top of the connecting part 23 is provided with a support plate 24 that can be elastically moved up and down. The outer edge of the support plate 24 is located inside the outer edge of the connecting part 23, and the edges of the support plate 24 are all located inside the edges of the connecting part 23, so as to avoid the support plate 24 interfering with the installation of the connecting part 23 when the connecting part 23 enters the mounting cylinder 4. The top surface of the support plate 24 is provided with an elastic pad 241 that protrudes upward and can abut against the top of the inner wall of the mounting cylinder 4. The elastic pad 241 can be made of rubber or silicone material. The support plate 24 forms a support on the elastic pad 241. When the mounting cylinder 4 and the connecting part 23 are installed in place, the elastic pad 241 abuts against the top inner side of the mounting cylinder 4, increasing the buffering capacity when the standing platform 3 is installed on the mast 2. The top of the connecting part 23 is provided with a fixing groove 232, and the bottom of the support plate 24 is provided with a connecting seat 242 that can move up and down in the fixing groove 232. The connecting seat 242 is located at the bottom of the support plate 24, and it slides against the inner wall of the fixing groove 232. The connecting seat 242 can drive the support plate 24 to slide up and down in the fixing groove 232. The bottom is equipped with multiple telescopic springs 233 that connect to the bottom of the connecting seat 242. These telescopic springs 233 are located at the bottom of the fixing groove 232 and connected to the bottom of the connecting seat 242, allowing the connecting seat 242 to move elastically up and down. This provides a buffering effect when the mounting cylinder 4 is installed on the connecting part 23, preventing excessive impact when the standing platform 3 and mounting cylinder 4 are installed on the upper end of the mast 2, which could damage the mast 2 and mounting cylinder 4 or generate excessive noise. When the mounting cylinder 4 is fitted onto the connecting part 23, the mounting cylinder 4... The support plate 24 at the top of the connecting part 23 forms a compression, and the telescopic spring 233 provides an elastic force to buffer the movement. Multiple axially arranged limiting grooves 234 are provided on the inner wall of the fixing groove 232. A limiting slider 243 that cooperates with the limiting groove 234 is provided on the side wall of the connecting seat 242. When the connecting seat 242 slides up and down, the limiting slider 243 slides within the limiting groove 234. The limiting groove 234 limits the movement range of the limiting slider 243, preventing the connecting seat 242 from disengaging from the fixing groove 232. The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
