[0004] The purpose of the utility model is to provide a new type of easily steerable grinding machine, which can be easily steered during use by improving the steering mechanism of the grinding machine.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is:

[0006] A new type of easily steerable grinding machine includes a frame. Universal walking wheels and walking steering wheels are arranged on the frame. The walking steering wheels are installed on a wheel frame, and the wheel frame is suspended and installed on the frame through a slewing bearing; the rotating part of the slewing bearing is driven by a gear to rotate, and drives the wheel frame to rotate to realize the steering of the walking steering wheels; the gear is driven by a telescopic rod to rotate reciprocally.

[0017] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the following further elaborates the utility model in combination with specific embodiments.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0019] The utility model is a new type of easily steerable grinding machine, which is used for grinding construction on the ground.

[0020] The grinding machine has a frame 1, on which a universal traveling wheel and a traveling steering wheel are provided. A grinding head is also installed on the frame. The machine is driven to move by the universal traveling wheel, and the traveling steering wheel is used for steering. The grinding head performs grinding construction on the ground, and usually multiple grinding heads are provided. For example, three grinding heads are provided.

[0021] Both the walking steering wheel and the universal walking wheel are installed on the wheel frame, and then the wheel frame is installed on the machine frame. The walking steering wheel is power-connected to a power system formed by a driving motor and a speed reducer, and the driving motor drives the walking steering wheel to rotate and move through the speed reducer. This is the conventional setting method of a grinding machine. This technical solution improves the steering mechanism part of the walking steering wheel. The specific description is as follows:

[0022] As Figure 3 shown, the wheel frame of the walking steering wheel of this grinding machine is suspended and installed on the machine frame 1 through a slewing bearing. Under the action of the slewing bearing, it can rotate. The slewing bearing includes a fixed part and a rotating part. Both the fixed part and the rotating part are circular ring structures, and the rotating part is rotatably arranged in the fixed part. Inner teeth are provided on the rotating part. At the same time, a gear 4 is provided to mesh with the inner side of the rotating part. The rotating part of the slewing bearing is driven by the gear 4 to rotate, and then can drive the wheel frame to rotate, further realizing the steering of the walking steering wheel.

[0023] The most important improvement point of this grinding machine is to set an expansion rod 2 and a swing rod 3 to drive the gear 4 to reciprocate. The rotation of the gear 4 drives the rotating part of the slewing bearing 7 to rotate, and then drives the walking steering wheel 6 to rotate through the wheel frame 5.

[0024] Here, the slewing bearing 7 used is an internal gear type slewing bearing. The slewing bearing 7 has a rotating part and a fixed part, and the rotating part is rotatably installed in the fixed part. The rotating part of the slewing bearing 7 has inner teeth. The gear 4 is meshed with the rotating part of the slewing bearing 7. The gear 4 is also hinged and installed on the machine frame 1. Usually, the gear 4 is connected to the swing rod 3, and the swing rod 3 is installed on the machine frame 1, so that the gear 4 is installed on the machine frame 1 through the swing rod 3. The slewing bearing is a purchased part.

[0025] As Figure 2 shown, an expansion rod 2 is set on the machine frame 1. The expansion rod 2 is placed horizontally, and the telescopic end of the expansion rod 2 moves in the horizontal plane. The telescopic end of the expansion rod 2 is hinged and connected with a swing rod 3, and the other end of the swing rod 3 is connected to the gear 4. When the telescopic end of the expansion rod 2 moves, the swing rod 3 can be swung. The swing of the swing rod 3 drives the gear 4 to rotate at the same time, and the swing of the swing rod 3 is centered on the axis of the gear 4. The swing rod 3 can swing, and the steering angle is controlled by the swing. Furthermore, the walking steering wheel 6 is steered and controlled by the swing rod 3 driving the rotation through the gear 4.

[0026] As Figure 2As shown in the figure, the fixed end of the telescopic rod 2 is hinged to the frame 1, and the telescopic and movable end of the telescopic rod 2 is hinged to the swing rod 3. When the telescopic and movable end of the telescopic rod 2 makes a telescopic movement, its fixed end also makes a small adaptive swing, so that the swing rod 3 can swing within an angular range.

[0027] The telescopic rod 2 can be an electric telescopic rod or a hydraulic telescopic rod, preferably a hydraulic telescopic rod, which has a large driving force. The hydraulic telescopic rod is provided with hydraulic power by a hydraulic system configured on the grinding machine. A hydraulic oil tank, a hydraulic pump, oil pipes, valves, etc. are arranged on the grinding machine to form a hydraulic system.

[0028] In the specific implementation of this grinding machine, as Figure 1 shown, a universal walking wheel 8 is arranged on the frame 1, and two walking steering wheels 6 are arranged; and the universal walking wheel 8 and the walking steering wheels 6 are distributed in a triangle. The walking steering wheels 6 are responsible for walking and steering. The universal walking wheel 8 follows when the walking steering wheels 6 make a turn. Figure 1 The walking steering wheels are arranged on both sides of the lower middle part, and the universal walking wheel 8 is arranged above.

[0029] When this grinding machine is in use, the whole machine is driven to walk longitudinally by the two walking steering wheels 6. When a turn is needed, the telescopic rod 2 is controlled to act, so that the walking steering wheels 6 make a turn. When turning, the universal walking wheel 8 follows. After the turn is completed, the longitudinal walking work on another working surface is continued.

[0030] Compared with using a servo motor for steering drive, using a telescopic rod for steering drive can also save the processing cost of the machine. The telescopic rod has a lower cost than a servo motor. The grinding machine itself needs to be provided with a hydraulic system, and there are other hydraulic drive components on the grinding machine.

[0031] The present utility model uses a telescopic rod in cooperation with a swing rod to drive a gear to rotate, and then the gear drives a rotating member of a slewing bearing to rotate, thereby driving the wheel frame and the walking steering wheels to rotate. Using a telescopic rod as a driving mechanism is more convenient to control and more suitable for the working environment of the grinding machine.

[0032] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
