The utility model is realized by adopting the following technical solutions:

The utility model relates to an underground multifunctional side unloading rock loading machine for mines, which includes a crawler type traveling mechanism, a rotary movable platform, an operating room and a corresponding hydraulic system.

A lifting working device is installed on the rotary movable platform; the lifting working device includes an outer arm and an inner arm sleeved in the outer arm, the bottom of the outer arm is hinged with the rotary movable platform, and the middle part is connected with the piston rod of the lifting working cylinder. The end is hinged, the cylinder bottom of the lifting working cylinder is hinged with the rotary movable platform; a hydraulic winch is installed on the rotary movable platform; a lifting frame is installed at the end of the inner arm, and the end of the lifting frame is installed There is a fixed pulley; the drum of the hydraulic winch is wound with a wire rope, and the end of the wire rope bypassing the fixed pulley is connected to a lifting hook, and a limit block is installed at the end of the lifting hook.

When the lifting device is working, the lifting frame is connected to the end face of the inner arm with bolts, and the hydraulic winch is installed on the counterweight of the movable platform, and the object is lifted by turning the wheel of the hinge to drive the wire rope up and down. When hoisting, the boom swings up to the position through the extension of the lifting working oil cylinder, the inner arm is extended to the position, and at the same time, the winch disc is released, the hook is hung on the object to be hoisted, and the steel rope is tightened to lift the object.

The front part of the rotary movable platform is equipped with a side tilting shoveling device, and the side tilting shoveling device includes two booms that are symmetrically installed on the front end of the rotary movable platform through pin shafts, and the front ends of the two booms are jointly hinged and installed A bucket; a linkage arm is fixedly installed between the two booms, the middle part of the linkage arm is hinged to the end of the piston rod of the lifting working cylinder, and the cylinder end of the lifting working cylinder is connected to the rotating movable The platform is hinged; the upper part of the linkage arm is hinged to the cylinder end of the rollover working cylinder, the piston rod end of the rollover working cylinder is hinged to one end of the rollover connecting arm, and the other end of the rollover connecting arm Fastened to the back of the bucket.

When the side tilting scraper device is working, center the movable platform, operate the side tilting working cylinder to put the bucket flat on the ground, control the main vehicle to move forward to fill the bucket with goods, and then operate the lifting working cylinder to make the boom While ascending, operate the side tilting working cylinder to start retracting the bucket. After ascending to the right position, manipulate the rotary movable platform to turn left and right to the top of the mine car, manipulate the bucket to dump the cargo to the left or right, otherwise, manipulate the boom to lower the bucket and turn the platform , the bucket rolls over and is recovered in place, and then leveled and lowered in place, and the cycle operation is performed again.

The rock unloading device on this side is mainly used for loading and unloading and short-distance transportation in the tunnel. The biggest feature of this device is that the bucket can rotate 180o around the center of the front part of the vehicle, so that the cargo can be easily unloaded to any position of 180o in the front half during loading and unloading operations. It can be realized by simply rotating the movable platform without rotating the chassis of the car body. . At present, the same type of crawler-type side unloading rock truck bucket and the body of the same type of mine underground are connected as one. When loading and unloading, the direction of the chassis of the car body must be changed to realize it. Due to the limited width of the tunnel, the steering radius required for the chassis of the car body during loading operations is relatively large, and the front and rear movement distance of the car body is long, resulting in a long operating cycle. Moreover, the soil quality of the tunnel ground is relatively soft, and when the vehicle turns, the crawlers on both sides move forward and backward with great resistance, resulting in difficult steering and low operating efficiency. The rotary platform operation method adopted in the design of this vehicle completely solves the above-mentioned problems. At present, the design scheme of this application has greatly improved the operation efficiency and operation simplicity in the underground trial, and has been well received by the mine side.

The utility model has a reasonable design and a simple structure, provides a crawler vehicle that can perform various operations freely in the roadway, greatly reduces the labor intensity of workers, improves work efficiency, and has important application value.
