Description

The invention relates to the mining industry and can be used mainly for loading rock mass into dump trucks during continuous operation of mining combines.

A device for the continuous loading of railway gondola cars with rock mass when working with a continuous excavation machine, including a frame on which a swivel funnel with a dispensing sleeve and a material flow distributor are mounted. During operation, the device is suspended on a dump conveyor, for example, a bucket wheel excavator [1].

This device has functional limitations for working with quarry combines and cannot be used to work with them.

Known self-propelled hopper for loading dump trucks [2]. Self-propelled hopper-dispenser includes a portal with running trolleys, on which hopper containers with gates are installed, a loading device made in the form of a funnel. Material enters the hoppers through a hopper and an open shutter. When the hopper tank is filled to a predetermined level, the sensor is triggered, and the material flow is directed to fill the second hopper.

Self-propelled hopper has a large number of gears that limit the reliability of continuous operation of the structure.

Known boot device for loading a dump truck and a complex for loading dump trucks [3-4]. The loading device [3] contains a frame, a hopper mounted on it, a shutter with movable plates and a drive for closing and opening it. The shutter is opened by the influence of the dump truck body on the shutter bracket, when the dump truck moves backward, while the body is filled with rock mass. After filling the body, the dump truck moves forward from under the loading device and the shutter automatically closes. The loading device is non-self-propelled and moves from place to place on a slide.

The closest in technical essence is the complex for loading dump trucks [4], in which two identical loading modules are involved with the possibility of their rearrangement and supply of rock mass to them through an excavator. Bunkers are mounted on frames, the capacity of which corresponds to the carrying capacity of used dump trucks.

This complex for loading dump trucks is not capable of fulfilling the task of loading the rock mass during continuous operation of the combine due to the design features (lack of a movement drive for the complex modules) and functional (automatic continuous following of the excavating machine) features of the complex, including positioning of bins relative to the loading device of the combine . To fill the hopper of the loading device, an increase in the length of the standard conveyors of quarry combines will be required, which will lead to an increase in the mass, dimensions and cost of combines [5]. When turning the conveyor console from one loading module to another, it will be necessary to stop the combine, therefore, downtime will appear and productivity will decrease.

The technical result consists in improving the technological efficiency of the complex, which automatically combines the positioning processes of one of the bunkers when loading into a dump truck with the positioning of another bunker for loading from the conveyor of a mining combine during the working stroke of a mining combine with uninterrupted operation of a mining combine without downtime. Both bunkers are located in one module, with sequential loading by a conveyor of a mining combine, the bunkers are lowered and the height of their upper edge provides the possibility of loading the conveyor. During sequential unloading, bunkers with the help of hydromechanisms rise, rotate and move longitudinally, providing uniform loading of the dump truck body.

The technical result is achieved by the fact that in the method of loading rock mass into dump trucks, including the ability to move modules with hoppers and feeding rock mass into hoppers with a capacity corresponding to the load capacity of used dump trucks, the implementation of independent processes for positioning one of the hoppers when loading into a dump truck with the positioning of another hopper under loading, the implementation of independent processes for positioning bins occurs simultaneously with the working process of a mining combine and automation of the process of orientation of the complex for loading relative to the quarry harvester, and the dump truck relative to the complex for loading, while the implementation of independent processes for positioning the bunkers occurs by moving the frames of the bunkers in the vertical plane and the carriage of the bunkers in the horizontal plane and is controlled by vertical movement mechanisms and mechanisms of horizontal movement, while the bunkers through articulated connections with the carriages have there is the possibility of rotation in the vertical plane with the help of telescopic rotation mechanisms, and the frames of the bunkers, when moving, enter into interaction by means of sliding supports with vertical guides.

A complex for loading, containing modules located in the bottom with the possibility of their movement and feeding the rock mass into hoppers mounted on the frames with a capacity corresponding to the capacity of the dump trucks used, and including providing independent processes for positioning one of the hoppers when loading into a dump truck with the positioning of another hopper for loading is equipped with vertical guides of the frame of the modules, the interaction with which includes sliding bearings of the frames of the bunkers, vertical mechanisms movement, associated with sliding bearings, horizontal movement mechanisms mounted on the frames of the bins and connected with the bunker carriages for positioning the bunkers in the horizontal plane, and telescopic bunker rotation mechanisms in the vertical plane relative to the articulated joints, an automatic control system for the functioning of the complex, while automation of the process of orientation of the complex relative to the quarry combine and relative to the dump truck in the process of During the operation of the quarry combine, the complex is equipped with positioning sensors mounted on the frame of the complex and connected to the automatic control system, and control sensors are placed on the bottoms of the bunkers to control the loading of bunkers with rock mass, while the automatic control system contains a microprocessor with a control unit, a hydraulic control panel and electric generator.

The possibility of forming the required sequence of actions by the proposed means allows us to solve the problem, determines the novelty, industrial applicability and inventive step of development.

The complex for loading is shown in the drawings.

Figure 1 is a General view of the complex for loading, where the front hopper is shown in the initial, lower position for loading the rock conveyor, and the rear hopper is in the raised position after loading the conveyor (not in the initial) to more accurately indicate the positions related to him; figure 2 is a top view of figure 1.

Complex 1 for loading contains one common frame of modules 2 for both modules 3, 4. Modules 3, 4 contain frames of bins 5, 6 on which carriages 7, 8 are installed. Carriages 7, 8 are connected to the hinges 9, 10 with hoppers 11, 12 with a capacity corresponding to the capacity of the used trucks. The sliding bearings 13 of the frames of the bins 5, 6 are connected with the mechanisms of vertical movement 14 and interact with the vertical guides 15 of the frame of the modules 2. The mechanisms of horizontal movement 16 are mounted on the frames of the bins 5, 6 and connected with the carriages 7, 8 for positioning the bins 11, 12 in the horizontal plane 17. On the frames of the bins 5, 6 are fixed telescopic rotation mechanisms 18 of the bins 11, 12 in the vertical plane 19 relative to the hinges 9, 10. To automate the process of orientation of the complex 1 relative to the quarry of the combine 20 and relative to the dump truck 21 during movement during the operation of the mining combine 20, the complex 1 is equipped with positioning sensors 22 mounted on the frame 23 of the complex 1 and connected with the automatic control system 24 mechanisms of the functioning of the complex 1. To control the loading of bunkers 11, 12 with the rock mass on the bottoms 25 bins 11, 12 placed control sensors 26. The automatic control system 24 contains a microprocessor with a control unit 27, a control panel for the hydraulic system 28 and an electric generator 29. The rock mass under is fed into the bunkers 11, 12 with a conveyor 30. Complex 1 is equipped with a buffer 31.

The method of loading rock mass into dump trucks is implemented as follows.

The quarry harvester 20, moving along the face, destroys the rock and conveyes rock mass through the conveyor 30 to the hopper 11 of complex 1, which is in the lower position. In the initial position, both hoppers 11, 12 are in the lower position. When the bunker 11 is fully loaded, the sensors 26 located on the bottom 25 are triggered to disable loading. The implementation of independent processes of positioning the bunkers 11, 12 occurs simultaneously with the working process of the quarry combine 20 during the automation of the orientation process of complex 1 for loading the rock mass obtained using the quarry combine 20 and the dump truck 21 relative to complex 1. Complex 1 follows the quarry combine 20 remotely controlled from it through an automatic control system 24 containing a microprocessor with a control unit 27, a control panel for the hydraulic system 28 and an electric generator 29 At this time, the dump truck 21, moving in reverse, rests against the buffer 31 of complex 1, the sensor 22 is activated, located on the frame 23, a command is sent to load the rock mass into the dump truck 21. At this time, the conveyor 30 of the mining combine 20, loading the hopper 11, moves to position above the hopper 12 of the module 4, which is in the lowest position. The hopper 12 is loading. At this time, the module 3, including the hopper frame 5 and the hopper 11, using sliding bearings 13, which interact with the vertical guides 15 of the module frame 2, is moved in the vertical plane by the vertical movement mechanisms 14. When the hopper frame 5 module 3 will reach its extreme upper position, the carriage 7 of the hopper 11 using the horizontal movement mechanism 16 is shifted towards the dump truck 21 to position the hopper 11 in the horizontal plane 17 at the desired distance about t of the truck 21 and through a swivel connection 10 with the carriage 7 and the telescopic rotation mechanism 18 is rotated in a vertical plane 19 to load the truck 21. The truck 21 is loaded. Then the hopper 11 is moved to its original lower position. After loading the hopper 12, the conveyor 30 is positioned above the hopper 11, and the module 4, including the frame of the hopper 6, using sliding bearings 13, which interact with the vertical guides 15 of the frame of the modules 2, is moved in the vertical plane by the mechanisms of vertical movement 14. When the frame of the hopper 6 module 4 will reach its extreme upper position, the carriage 8 of the hopper 12 using the horizontal movement mechanism 16 is shifted towards the dump truck 21 to position the hopper 12 in the horizontal plane 17 to SG distance from the dump 21 and through the hinge connection 9 with the carriage 8 and the rotation of the telescopic mechanism 18 is rotated in the vertical plane 19 to download the next dump 21.

The proposed method of loading rock mass into dump trucks through a complex for loading allows to ensure the continuity of the work of a mining combine and overloading the rock mass. The kinematic scheme for moving the hoppers allows them to be loaded in the lower position by the conveyors available on the surface miners and to load dump trucks shocklessly and evenly.
