Wheel-crawler dual-purpose multifunctional belt opening machine

Abstract

The invention discloses a wheel-track dual-purpose multifunctional belt opening machine which comprises a frame, a track walking chassis and a wheel type walking mechanism, and the wheel type walking mechanism comprises a front axle assembly, a front axle support, a front axle push-pull oil cylinder, a rear axle assembly, a rear axle support and a rear axle push-pull oil cylinder. The front axle assembly is assembled with the frame through a front axle support and driven by a front axle push-pull oil cylinder to ascend or descend, and the rear axle assembly is assembled with the frame through a rear axle support and driven by a rear axle push-pull oil cylinder to ascend or descend. The wheel-track dual-purpose multifunctional belt opening machine has a track type walking mode and a wheel type walking mode at the same time, the front axle push-pull oil cylinder and the rear axle push-pull oil cylinder drive the front axle assembly and the rear axle assembly to ascend and descend so that the walking modes can be switched, and the whole machine has the advantage of being good in cross-country performance in the track type walking mode; and moreover, the device has the advantage of high efficiency during wheel type transition (a plate trailer is not needed for consignment), and the convenience, the stability and the adaptability in the transfer process can be improved.

Description

technical field [0001] The invention relates to the technical field of belt unwinding machines for forest use, in particular to a dual-purpose multifunctional belt unwinding machine for wheels and shoes. Background technique [0002] The forest belt opener is mainly used for daily maintenance of forest fire barriers, forest roads, river emergency barriers and opening of emergency fire passages, etc. It is a modern machine for building a forest fire barrier system and repairing the fire barrier. [0003] The forest belt unwinding machine is based on the crawler excavator. It can be equipped with a belt unloading head with a crushing function to realize forest belt unpacking. At the same time, it can also be equipped with hydraulic shears, breaking hammers, hydraulic clamps, hydraulic push teeth and medium-sized excavators. Conventional attachments can realize the functions of shearing, impact crushing, grabbing, cutting grass and shrubs and medium-sized excavators at the sam...

Problems solved by technology

But there are also significant disadvantages: slow moving speed, poor maneuverability, the maximum design speed is generally 5-7KM / H, long-distance movement relies on carts or trailers for transportation, and mountain roads are usually narrow, and carts often need to be driven It is very inconvenient to turn around at the open area at the end of the road, which greatly increases the construction cost and reduces the construction efficiency

Its disadvantages are as follows: 1. Since it is necessary to consider switching to the crawler walking mode, the raised wheel mechanism must be high enough so that the passability of the whole machine can meet the requirements, so the height of the crawler walking frame (frame) from the ground must be high enough , to meet the spatial layout of the gearbox + drive shaft, so that the center of gravity of the whole machine will rise, and the driving and working stability will be greatly affected; 2. The space under the crawler walking frame is occupied by the gearbox and the drive shaft. The lower space is limited, and it is easy to interfere with the ground and damage the transmission system when passing through steep slopes and complex road conditions; 3. The track mode of the whole machine adopts hydraulic drive and control, and the brake system adopts air control structure, which makes the system configuration and The control is more complicated, and the reliability and sensitivity of the air control components are difficult to meet the expected requirements
