Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, specifically to a telescopic multi-mast aerial work platform. Background Technology

[0002] Mast-mounted aerial work platforms are widely used in municipal maintenance, power construction, and building decoration, among other fields. Their core function is to transport personnel and tools to designated high-altitude locations via a lifting mechanism. For their traditional structure, please refer to [link / reference needed]. Figure 1 As shown, it mainly consists of a chassis, turntable, mast, boom, and work platform. The components work together to achieve lifting and rotation: the chassis provides stable support and mobility, the turntable enables the equipment to rotate horizontally, the mast, as the main lifting structure, achieves vertical height adjustment through extension or folding, and the boom is connected to the top of the mast, which can drive the work platform to rotate horizontally or swing slightly within a certain range, ultimately bringing the platform to the work position.

[0003] However, the existing structural design of mast-type aerial work platforms has significant limitations: see Figure 2 As shown, because its lifting function mainly relies on the vertical raising and lowering of the mast, while the boom can only rotate at a limited angle at the top of the mast, the lifting height of the equipment is much greater than its horizontal extension length. This "tall and narrow" structural characteristic means that when it is necessary to extend a long distance horizontally (such as crossing obstacles or constructing the facade of a large-span building), conventional vehicle models cannot cover the target work area, and large telescopic boom aerial work platforms or other specialized equipment must be used.

[0004] At the same time, its insufficient horizontal reach also limits its application in scenarios that require large-scale coverage, such as disaster relief and rescue and the installation of large equipment, making it difficult to meet the actual needs of diverse high-altitude operations.

[0005] Therefore, how to overcome the structural limitations of the unbalanced "height-to-length ratio" of traditional mast-type aerial work platforms and improve horizontal extension capabilities while ensuring lifting height has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problems of insufficient horizontal extension capability and limited operating range of existing aerial work platforms, and to provide a telescopic multi-dimensional mast aerial work platform.

The mounting top plate is detachably connected to the free end of the lifting mast, the mounting side plate is perpendicularly connected to the mounting top plate, and the first connecting frame is disposed on the mounting side plate and detachably connected to the horizontal telescopic mechanism.

[0011] In one embodiment of this utility model, the driver is provided with a second connecting frame at one end facing the lifting mast, and the fixed arm is provided with a third connecting frame at one end facing the lifting mast. The second connecting frame and the third connecting frame are both connected to the first connecting frame by bolts.

[0012] In one embodiment of the present invention, the horizontal telescopic mechanism further includes a plurality of friction blocks, which are disposed between the telescopic arm and the fixed arm, and are respectively connected to the telescopic arm and / or the fixed arm.

[0013] In one embodiment of the present invention, the driver includes a fixed sleeve and a lifting rod. The fixed sleeve is connected to the end of the lifting mast. One end of the lifting rod is inserted into the fixed sleeve, and the other end is connected to the telescopic arm, and can extend and retract along the extension direction of the fixed arm.

[0014] In one embodiment of the present invention, the support mechanism includes a support frame and a welding frame. The support frame includes a main frame body and a connecting beam. The connecting beam is disposed on the main frame body and has a plurality of connecting rings thereon.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Example:

[0032] See Figure 3 and Figure 4 As shown, this embodiment provides a telescopic multi-mast aerial work platform, which includes: a moving mechanism 100; a lifting mast 200, which is disposed on the moving mechanism 100 and can extend and retract in the vertical direction; a horizontal telescopic mechanism 300, which includes a driver 310, a fixed arm 320, and a telescopic arm 330, wherein the fixed arm 320 extends in the horizontal direction and one end is connected to the free end of the lifting mast 200, the telescopic arm 330 is disposed inside the fixed arm 320 and can extend and retract in the extension direction of the fixed arm 320, and the driver 310 is connected to the telescopic arm 330; and a support mechanism 400, which is connected to the free end of the telescopic arm 330 to support the load.

[0033] The telescopic multi-mast aerial work platform described in this embodiment uses a moving mechanism 100 to provide a foundation for both movement and fixation, a lifting mast 200 to extend the height dimension, a horizontal telescopic mechanism 300 to overcome horizontal operational limitations, and a support mechanism 400 to directly connect to the load as the terminal carrier. These four components form a linked system through rigid connections and power transmission. The lifting mast 200 and the horizontal telescopic component work together to overcome the structural limitations of traditional mast-type aerial work platforms that result in an imbalance between the moving height and horizontal distance. This ensures a high lifting height while enhancing horizontal extension capabilities. Therefore, compared to traditional aerial work equipment, this application offers advantages such as wide applicability, flexible use, high operational accuracy, and high stability, providing a new approach to the design of aerial work equipment.

[0034] Specifically, in this embodiment Figure 3 The structural design of the telescopic multi-mast aerial work platform was demonstrated in its extended state. Figure 4 The structural design of the telescopic multi-mast aerial work platform in its retracted state is demonstrated. Based on the above comparison, it is clear that the operating range of this application is significantly larger than that of other applications. Figure 1 , Figure 2 The mast-type aerial work platform shown has been significantly enlarged.

[0035] Specifically, in this embodiment, the mobile mechanism 100 is the basic support and mobile carrier of the entire aerial work platform. The mobile mechanism 100 includes a transport vehicle 110 and a turntable 120. The transport vehicle 110 moves in the work area. The turntable 120 is mounted on the transport vehicle 110 and rotates around the rotation center line 1001. The lifting mast 200 is mounted on the turntable 120 and moves synchronously with the turntable 120, thereby driving other structures installed on it to move or rotate in the work space. Furthermore, the rotation center line 1001 extends vertically and passes through the center of the turntable 120.

[0036] In this embodiment, the lifting mast 200 includes a fixed part 210, a first telescopic part 220, and a second telescopic part 230. The fixed part 210 is disposed on the moving mechanism 100. The first telescopic part 220 is disposed within the fixed part 210 and extends and retracts vertically relative to the fixed part 210. The second telescopic part 230 is disposed within the first telescopic part 220 and extends and retracts vertically relative to the first telescopic part 220, thereby realizing a multi-section telescopic action. In actual use, the operator can adaptively adjust the vertical extension length of the lifting mast 200 according to the needs of the actual operation scenario. Other numbers of telescopic parts can also be provided. This utility model does not impose specific limitations on this.

[0037] See Figure 5 and Figure 6 As shown, the actuator 310 includes a fixed sleeve 311 and a lifting rod 312. The fixed sleeve 311 is connected to the end of the lifting mast 200. One end of the lifting rod 312 is inserted into the fixed sleeve 311, and the other end is connected to the telescopic arm 330, and can extend and retract along the extension direction of the fixed arm 320. Specifically, the actuator 310 in this embodiment is preferably a linear hydraulic cylinder. In different embodiments, the actuator 310 can be configured as a cylinder, motor, or other structure according to actual usage requirements. This utility model does not impose specific limitations on this.

[0038] The lifting mast 200 in this embodiment further includes an assembly assembly 240, which is disposed at the free end of the lifting mast 200 to connect to the horizontal telescopic mechanism 300. The assembly assembly 240 includes a mounting top plate 241, a mounting side plate 242, and a first connecting frame 243. The mounting top plate 241 is detachably connected to the free end of the lifting mast 200, the mounting side plate 242 is perpendicularly connected to the mounting top plate 241, and the first connecting frame 243 is disposed on the mounting side plate 242 and detachably connected to the horizontal telescopic mechanism 300. Specifically, the first connecting frame 243 has three connecting holes arranged in sequence along the vertical direction. The end of the driver 310 facing the lifting mast 200 has a second connecting frame 313, which is connected to two connecting holes in the first connecting frame 243 by bolts 500.

[0039] Correspondingly, a third connecting frame 321 is provided on one end of the fixed arm 320 toward the lifting mast 200. Each of the third connecting frames 321 is connected to the connecting hole in the middle of the first connecting frame 243 by bolts 500. Based on this, this application enables flexible disassembly and reassembly between the lifting mast 200 and the horizontal telescopic mechanism 300, facilitating maintenance and installation. Similarly, a fourth connecting frame 331 is provided on the telescopic arm 330, and the fourth connecting frame 331 is connected to the support mechanism 400 by bolts 500.

[0040] See Figure 7 As shown, the horizontal telescopic mechanism 300 further includes multiple friction blocks 340, which are disposed between the telescopic arm 330 and the fixed arm 320. The friction blocks 340 are respectively connected to the telescopic arm 330 and / or the fixed arm 320 to prevent the telescopic arm 330 from colliding with the inner surface of the fixed arm 320 during telescopic movement, thereby improving the movement accuracy and the service life of the horizontal telescopic mechanism 300. Specifically, in this embodiment, friction blocks 340 are connected to both the fixed arm 320 and the telescopic arm 330.

[0041] See Figure 8 As shown, the support mechanism 400 includes a support frame 410 and a welding frame 440. The support frame 410 includes a main frame 411 and a connecting beam 412. The connecting beam 412 is disposed on the main frame 411 and has multiple connecting rings 413 thereon. The welding frame 440 is supported on the main frame 411 and is detachably connected to the multiple connecting rings 413. Preferably, the support frame 410 is an "L"-shaped frame, used to support and drive the welding frame 440 to move. The connecting beam 412 can be detachably connected to the welding frame 440 through the multiple connecting rings 413 thereon. Further, see... Figure 9As shown, the welding frame 440 includes a welding rod 441, a base plate 442, and a movable stop bar 443. The welding rod 441 is fixed to the base plate 442 to enclose a support space. The movable stop bar 443 is disposed on one side of the support space and slidably connected to the welding rod 441. The welding rod 441 can be connected to a connecting ring 413. The base plate 442 supports the working load, and the movable stop bar 443 provides a passage for the load to enter and exit the support space.

[0042] Furthermore, to improve the operational safety of this aerial work platform, the support mechanism 400 in this embodiment also includes at least one weight sensor 420 and a display 430. Multiple weight sensors 420 are respectively connected to the display 430, and all weight sensors 420 are disposed between the main frame 411 and the welding frame 440. Specifically, in this embodiment, four weight sensors 420 are distributed at different points on the main frame 411 to accurately measure the load inside the welding frame 440. The measurement results can be fed back to the display 430 in real time, further improving the ease of operation of this aerial work platform. In different embodiments, the number and specific connection positions of the weight sensors 420 can be adaptively adjusted according to actual usage requirements; this utility model does not impose specific limitations in this regard.

[0043] In summary, the telescopic multi-dimensional mast aerial work platform described in this utility model uses a moving mechanism 100 to provide a foundation for both movement and fixation, a lifting mast 200 to expand the height dimension, a horizontal telescopic mechanism 300 to overcome horizontal operational limitations, and a support mechanism 400 to directly connect to the load as the terminal carrier. These four components form a linked system through rigid connection and power transmission. The lifting mast 200 and the horizontal telescopic component work together to overcome the structural limitations of traditional mast-type aerial work platforms that result in an imbalance between the moving height and horizontal distance. While ensuring the lifting height, this enhances the horizontal extension capability. Therefore, compared to traditional aerial work equipment, this application offers advantages such as wide applicability, flexible use, high operational precision, and high stability, providing a new approach to the design of aerial work equipment.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
