Anti-rollover building demolishing machine with protective frames

Abstract

The invention relates to the technical field of mine construction machines, in particular to an anti-rollover building demolishing machine with protective frames. The anti-rollover building demolishing machine with the protective frames comprises a walking device and an upper rotary platform. The walking device comprises a lower vehicle frame. A left crawler frame, a main vehicle frame body and a right crawler frame are arranged on the lower vehicle frame. The upper rotary platform comprises an upper vehicle frame. A cab, a hydraulic transmission device and a power device are arranged on the upper vehicle frame. The anti-rollover building demolishing machine is characterized in that four lifting multi-stage hydraulic cylinders and a tilt angle sensor are arranged on the lower end face of the main vehicle frame body, and a display device and an alarm device are arranged in the cab; two first arch-shaped protective frames and the second protective frame which is oval and located on the first protective frames are arranged on the upper vehicle frame, the first protective frames are connected with the upper vehicle frame through a damping device, the two ends of a support arm are correspondingly hinged to the upper vehicle frame and a high-frequency crushing hammer, and the support arm and the high-frequency crushing hammer are correspondingly connected with a first hydraulic cylinder and a second hydraulic cylinder; and anti-rollover devices are arranged on the lower end face of the upper vehicle frame body. The anti-rollover building demolishing machine is reasonable in structure, convenient to operate and capable of achieving the safe and efficient building demolishing work.

[0002] With the development of the society and the high requirements of building quality, buildings with brick-concrete structure and prefabricated panel structure in the 1980s and 1990s will be gradually eliminated. At present, there are roughly three ways to demolish buildings: one is manual demolition, that is, large-scale demolition is done manually. The hammer breaks the floor point by point. Although this method can recover steel to a greater extent, the construction period is long and labor-intensive, and the construction workers are always exposed to danger. If they are accidentally hit by falling building debris , it is very dangerous; the second is the blasting method. Although this method can collapse the building at one time, the construction period for slag removal is too long, the steel recycling is difficult, and it will cause serious environmental pollution. The third is an excavator. A common excavator is usually composed of a working device, an upper turntable and a traveling mechanism. The working device includes a boom, a stick, a bucket, a hydraulic cylinder, a connecting rod, a pin and a pipe. The upper turntable is composed of engine, shock absorber main pump, main valve, driver's cab, slewing mechanism, slewing bearing, slewing joint, turntable, hydraulic oil tank, fuel tank, control oil circuit, electrical components, and counterweight. The traveling mechanism is composed of Track frame, crawler belt, guide wheel, supporting wheel, supporting wheel, final drive and tensioning device, using excavator to dismantle the building can greatly reduce labor intensity, but after the excavator in the prior art removes the building, the building suddenly If the driver's cab collapses, the operator's cab is likely to be crushed, and the operator is likely to be trapped and unable to leave the construction site quickly. What's more, the driver's cab is collapsed, and the operator will be very dangerous. If it is building debris, the excavator is likely to be unstable when it is moving forward or backward, and rollover will occur. This not only endangers the personal safety of the operators in the cab, but also if the excavator rolls over and hits buildings and pedestrians, it will be very serious. Dangerous, but also delayed the normal progress of building demolition operations
