Description

Technical Field

[0001] This invention belongs to the field of mechanical platforms, specifically relating to a multi-functional vehicle-mounted platform. Background Technology

[0002] In highway construction, retaining walls are often needed in sections prone to landslides to prevent natural disasters such as landslides, mudslides, and rockfalls. During this process, construction equipment requires multi-degree-of-freedom construction positions and an integrated material transportation method. This invention can meet the above functional requirements.

[0003] Compared with existing related patents, Chinese patent CN105967118 A discloses a vehicle-mounted multi-functional maintenance lifting platform. This invention uses guide rails mounted on the vehicle roof, with a mast-type lifting device mounted on the rails. The mast-type lifting device, powered by its own energy, can be raised vertically for operation. During operation, it can be extended to a vertical position; after completion, it can be retracted and placed on the vehicle roof. The retraction and extension are achieved by two hydraulic cylinders. This invention has a simple structure, is practical and reliable, and can greatly improve work efficiency and reduce pre-construction preparation work. However, this invention is not suitable for existing retaining wall construction conditions. The vehicle roof space and load-bearing capacity are limited, preventing the transport of multiple stones at once. The mast-type lifting device can only move above the vehicle roof; it cannot reach the construction position below the vehicle roof platform. The guide rails, hydraulic cylinder push seats, and mast mounting seats on the vehicle roof are all fixed installations and cannot be adjusted in multiple directions and angles, therefore, it is not suitable for existing retaining wall construction conditions.

The power source 5 is connected to the wire rope 3. A side guide wheel 6 for the moving beam assembly 50 is provided on the side of the moving beam assembly. A fixed pulley group 45 for lifting the working platform is provided on the tilting platform assembly 40. The wire rope 3 passes through the horizontal guide wheel 2, the vertical guide wheel 4, the side guide wheel 6, and the fixed pulley group 45 before connecting to the platform lifting pulley 60. A moving beam pushing cylinder 7 is provided between the moving beam assembly 50 and the rear fixed assembly 30.

[0029] See Figure 4 and Figure 5 The rear-end fixing assembly 30 includes a rear-end fixing side plate 32, a rear-end fixing top plate 34, and a mounting plate 36. The rear-end fixing side plate 32, the rear-end fixing top plate 34, and the mounting plate 36 together form a rectangular frame. A horizontal position locking mechanism 31 for the worktable is installed on the rectangular frame. An upper pad 37 is installed inside the rear-end fixing top plate 34, and a bottom pad 35 is installed on the mounting plate 36. A left-right clearance adjustment mechanism 33 is installed between the rear-end fixing side plate 32 and the moving beam assembly 50. A hydraulic cylinder mounting seat 38 is installed at the bottom of the mounting plate 36.

[0030] See Figure 6 The movable beam assembly 50 includes a first movable beam 51 and a second movable beam 52. A bottom fixing 53 is provided between the bottom of the first movable beam 51 and the bottom of the second movable beam 52.

This invention can solve the problem of vertical movement of the working face and material transportation. The rear fixed assembly 30 is installed on the vehicle slewing platform. The feeding trolley 20 moves to the rear end of the moving beam assembly 50. After loading, the feeding trolley 20 moves forward to the tilting platform assembly 40, realizing material transportation. The working platform 8 is lifted by a pulley system consisting of the working platform lifting pulley 45 and the platform lifting pulley 60, and guided by the rear limit wheel 43 and the front limit wheel 44, allowing the working platform 8 to move and receive materials.
