Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, specifically to a high-altitude mobile work platform. Background Technology

[0002] In municipal, water conservancy, and port and shipping infrastructure projects, gantry cranes are core lifting and hoisting equipment on site. With the commencement and completion of projects, gantry cranes need to be installed, dismantled, and relocated to other construction sites multiple times, and the installation and removal of bolts on the high-altitude end beams is a critical step. Traditional end beam bottom bolt installation and removal operations are limited by site conditions, operating height, cost control, and operational flexibility, often using a truck crane to lift a suspended platform, with workers inside the platform to install and remove the bolts. However, according to safety regulations for construction lifting equipment, truck cranes and similar equipment are strictly prohibited from using suspended platforms to lift personnel; this is a clear on-site prohibition. This construction method carries extremely high safety risks: during high-altitude operations, if the suspended platform's wire rope breaks or strong winds cause the platform to sway, workers are highly likely to fall from a height, resulting in injury or death. Clearly, traditional methods cannot meet the safety requirements for high-altitude end beam installation and removal.

[0003] Chinese patent document with application number 202222139600.9 discloses a mobile quick-disassembly work platform suitable for high-altitude edge operations, including a platform body, a hanging basket, a ladder, omnidirectional brake wheels, a screw jack, and a counterweight box. The hanging basket and counterweight box are symmetrically arranged at both ends of the platform body, and the hanging basket can rotate 180° vertically. The omnidirectional brake wheels are located below the platform body, and the screw jack is located above the platform body. The ladder is located on one side of the hanging basket. This mobile quick-disassembly work platform has the following shortcomings: 1) The hanging basket is an integrated structure and is fixedly connected to the double clamps of the main body through pin 7. On the one hand, it occupies a lot of space and is inconvenient to hoist and move. On the other hand, it is inconvenient to disassemble and assemble. 2) The main body is fixed by the cooperation of screw jack and counterweight box, which is complex in structure, inconvenient to operate and costly, and inconvenient to disassemble and assemble. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a high-altitude mobile work platform with a simple structure and convenient hoisting, moving, disassembly and operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A mobile aerial work platform includes a main body, a hanging basket, and a ladder. The hanging basket includes a first side frame, a second side frame, and a work platform. The top of the first side frame is movably connected to the bottom of the main body and locked by a locking device. Connecting rods are hinged between the two sides of the first and second side frames. One side of the work platform is hinged to the bottom of the first side frame, and the other side is hinged to the bottom of the second side frame. The connecting rods are parallel to the work platform. Pull ropes are connected to both sides of the top of the second side frame and the main body. The ladder is mounted on the main body and located between the top of the main body and the first side frame. A hanging frame is provided on the top of the main body, forming a downward-opening groove between the hanging frame and the main body. Rollers are provided on each side inside the groove.

[0006] As a further improvement to the above technical solution: The main body is provided with plug-in rods on both sides of the bottom, and the first side frame is provided with socket tubes on both sides of the top. The plug-in rods are plugged into the socket tubes and locked together by locking components.

[0007] The locking element is a locking pin or locking bolt that is radially inserted into the insertion rod and the socket tube.

[0008] Each of the first and second side frames has multiple connecting rods arranged at intervals.

[0009] The pull rope is detachably connected to the second side frame and / or the main body, or the middle part of the pull rope is detachably connected.

[0010] An auxiliary ladder is provided on the first side frame.

[0011] The bracket includes a telescopic frame and a side frame. One end of the telescopic frame is fixed perpendicularly to the main body, and the other end is fixed perpendicularly to the top of the side frame. The slot is formed between the side frame, the telescopic frame, and the main body.

[0012] The telescopic frame includes a first side frame and a second side frame. One end of the first side frame and the second side frame are movably connected and fixed by a locking member. The other end of the first side frame is fixedly connected to the side frame, and the other end of the second side frame is fixedly connected to the main body.

[0013] One end of the first side frame and the second side frame are respectively provided with a connecting pipe and a connecting rod, which are movably connected and fixed by a locking member.

[0014] The connecting tube is provided with a plurality of first radial locking holes arranged at intervals along the axial direction, and the connecting rod is provided with a plurality of second radial locking holes arranged at intervals along the axial direction. The locking element is a locking pin or locking bolt that passes through the corresponding first radial locking hole and second radial locking hole.

[0015] Compared with the prior art, the advantages of this utility model are: Taking the use of this utility model of a high-altitude mobile work platform on a lifting and hoisting equipment as an example, the bracket is hung on the top end beam of the lifting and hoisting equipment through the slot. Each roller abuts against the left and right sides and the top side of the end beam respectively. The basket is in the unfolded use state under the tension of the pull rope, that is, the first side frame and the second side frame are vertical or nearly vertical, and the work platform is horizontal or nearly horizontal. Under the action of external force, the bracket moves along the end beam to the work position with the main body and the basket. The operator can then climb down to the work platform through the ladder to install and remove the bolts at the bottom of the end beam. This aerial work platform has two main features. First, the second side frame of the hanging basket can rotate and translate relative to the first side frame to achieve both retracted and extended states. On the one hand, during hoisting, as long as the tops of the first and second side frames are suspended, the hanging basket automatically enters the retracted state, reducing space occupation and facilitating hoisting. Furthermore, it is easy to move after retraction. On the other hand, the top of the first side frame is movably connected to the bottom of the main body and locked in place by locking components, making assembly and disassembly convenient. Second, the main body is installed via a hanging bracket, resulting in a simple structure, convenient operation, low cost, and easy assembly and disassembly. Attached Figure Description
