Description

Technical Field

[0001] The utility model relates to an in-situ rotating wheel type mill feeding trolley device, belonging to the technical field of mill feeding. Background Art

[0002] The feeder trolley is an indispensable equipment in the working process of the mill. It is responsible for feeding the mill and smoothly delivering the ore or slurry into the mill for processing. When the mill is working, the cylinder is rotating. The feeder trolley must be flexible and light to cooperate with the cylinder to achieve the function of feeding without leakage. The traditional feeder trolley moves on the specified guide rail, which has high requirements for the working plane. In addition, the general mill operation is in a narrow space. The reversing of the feeder trolley is time-consuming and labor-intensive, and the engineering is cumbersome. There are also great safety hazards in manual reversing. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a wheeled mill feeding trolley device which has a small turning radius, is suitable for working in a narrow space environment and can rotate in situ, in view of the defects of the prior art.

[0004] To solve this technical problem, the utility model provides an in-situ rotating wheel mill feeding trolley device, comprising a feed hopper, a trolley bracket, a trolley base, wheels, a traveling mechanism, a steering mechanism, a bolt assembly, a control system, and a power supply; a rotating motor and a reducer, a helical gear, a coupling, and a main drive motor and a reducer. The trolley bracket is fixed to the trolley base by a bolt assembly, the wheels are welded to the trolley base, and the feed hopper is arranged above the trolley bracket; the traveling mechanism is provided with a main drive motor and a reducer, and the steering mechanism is provided with a rotating motor and a reducer, and the control system drives the rotating motor and the reducer and the main drive motor and the reducer respectively to realize driving and steering.

[0005] The traveling mechanism is provided with four main driving motors and couplings. The main driving motors connect the motor shafts with the wheel shafts through the couplings via keys for transmission, and the two shafts are on the same axis.

[0006] The steering mechanism is provided with four rotating motors and helical gears, and the rotating motors are driven by a pair of helical gears to achieve steering.

[0007] The control system includes a remote control end, a main processor, a signal receiving and processing module and a motor controller. The remote control end sends a signal, the signal receiving module feeds back to the main processor, the main processor sends an instruction to the motor controller to drive the motor speed, and the traveling mechanism drives the trolley base forward or backward; when turning, the steering mechanism receives instructions, adjusts the motor rotation angle, and realizes steering.

[0008] Beneficial effects: The feeding trolley of the utility model adopts a motor to independently drive the wheels to move forward, backward and turn, with high transmission efficiency and easy remote control. The in-situ steering wheel structure has a small steering radius and is suitable for operation in a narrow space environment. This method avoids the time-consuming and labor-intensive manual operation and the extremely high risk of danger, and enhances the diversity and efficiency of the operation.

DETAILED DESCRIPTION

[0015] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-Figure 5 As shown, the utility model provides an in-situ rotating wheel mill feeding trolley device, including a feed hopper 1, a trolley bracket 2, a trolley base 3, wheels 4, a traveling mechanism 6, a steering mechanism 7, a bolt assembly 8, a control system 9, a power supply 10, a rotating motor and a reducer 11, a helical gear 12, a coupling 13 and a main drive motor and a reducer 14. The trolley bracket 2 is fixed to the trolley base 3 by the bolt assembly 8, the wheels 4 are welded to the trolley base 3, and the feed hopper 1 is arranged above the trolley bracket 2; the traveling mechanism 6 is provided with a main drive motor and a reducer 14 to control the forward or reverse movement of the trolley; the steering mechanism 7 is provided with a rotating motor and a reducer 11, and the control system 9 drives the rotating motor and the reducer 11 and the main drive motor and the reducer 14 respectively to control the steering movement of the trolley; the traveling mechanism 6 and the steering mechanism 7 realize the separate functions of driving and steering to facilitate remote control.

[0017] The travel mechanism 6 is provided with four main drive motors and couplings 13. The main drive motors connect the motor shafts with the wheel shafts through the couplings 13 via keys for transmission, and the two shafts are on the same axis.

[0018] The steering mechanism 7 is provided with four rotating motors and helical gears 12. The rotating motors are driven by a pair of helical gears 12 to ensure correct meshing and realize steering. The helical gears are stable in transmission and have strong load-bearing capacity. When turning in situ, the control system 9 sends a signal to the steering mechanism 7 to adjust the rotation angle of the rotating motor so that the trolley can turn in situ. The turning radius is small and it is suitable for operation in a narrow space environment.

[0019] The control system 9 includes a remote control end, a main processor, a signal receiving and processing module and a motor controller. The remote control end sends a signal, the signal receiving module feeds back to the main processor, and the main processor sends an instruction to the motor controller to drive the motor speed, and the traveling mechanism 6 drives the trolley base 3 forward or backward; when turning, the steering mechanism 7 receives instructions, drives the steering motor and the reducer to work, and realizes steering by adjusting the rotation angle of the motor; the driving motor and the steering motor act separately, which is conducive to remote control and has high accuracy.

[0020] The utility model adopts motors to independently control the wheels. The whole device adopts 8 motors, 4 main drive motors, and 4 rotating motors. The forward, reverse and turning movements are controlled separately by the motors, which improves the limitation that the traditional feeding trolley can only move on tracks, reduces the requirements for the driving plane, increases the movement diversity of the feeding trolley, avoids dangerous situations that may occur during manual operations, broadens the scope of use, effectively shortens the maintenance time, and improves the use efficiency.
