Description

Technical Field

[0001] The utility model relates to the technical field of grinders, and particularly relates to an efficient self-migrating grinder. Background Art

[0002] Floor grinders are mainly used for grinding the ground. They can effectively polish terrazzo, concrete surfaces, epoxy mortar layers, and old epoxy floors, etc., making the concrete surface smooth, flat, meeting the roughness requirements and flatness requirements, and making the horizontal error of the concrete surface meet the technical requirements. They also have the characteristics of being portable, flexible, and high working efficiency.

[0003] Traditional grinders mainly consist of a vehicle body, a handrail device, and a machine head. Moving wheels are installed at the lower part of the vehicle body. Whether it is during work or in-field migration, it needs to be pushed forward or backward manually, and it cannot turn flexibly, resulting in inconvenient migration. In addition, the traditional grinder may damage the grinding disc when encountering potholed roads during migration. Content of the Utility Model

[0004] Purpose of the utility model: In order to overcome the above deficiencies, the purpose of the present utility model is to provide an efficient self-migrating grinder, which has a simple structure, reasonable design, and can realize the function of self-propelling without external power supply.

[0005] Technical solution: In order to achieve the above purpose, the present utility model provides an efficient self-migrating grinder, which includes a vehicle body, a grinding mechanism, and a guide wheel lifting mechanism. The grinding mechanism is arranged at the upper part of the front end of the vehicle body, and the grinding mechanism is arranged at the lower part of the front end of the vehicle body. Driving wheels and a driving wheel driving device are installed at the bottom of the vehicle body. A power box is arranged on the vehicle body, and there is a power source in the power box. The guide wheel lifting mechanism includes a lifting frame and a lifting driving device, and the power source is connected to the driving wheel driving device and the lifting driving device. The power source provides power to the guide wheel lifting mechanism and the driving wheels, so that the guide wheel lifting mechanism descends to lift the machine head, and the driving wheels can drive the entire grinder to move.

[0006] Furthermore, the grinding mechanism includes a gear box installed on the vehicle body. The upper part of the gear box is connected to a grinding motor, and the lower part of the gear box is installed with a grinding disc.

[0007] Furthermore, the lifting frame is a retractable quadrilateral structure. The lifting frame is hinged to a fixed frame arranged at the front end of the vehicle body through a hinge seat. The lifting drive device is an electric hydraulic rod. The two ends of the electric hydraulic rod are respectively hinged to the diagonals of the lifting frame. Universal wheels are installed on the lifting frame. A plurality of pin holes are provided at corresponding positions on the fixed frame and the hinge seat. The position of the lifting frame can be changed by locking through the pin holes at different positions between the hinge seat and the fixed frame. The electric hydraulic rod can share a set of power source with the drive wheels. The lifting frame is connected to the vehicle body through the hinge seat and the fixed frame. By selecting and locking the corresponding pin holes on the hinge seat and the fixed frame, the guide wheel lifting frame can be retracted or extended, which not only effectively reduces the overall volume but also organically combines with the working mode of the grinding machine.

[0008] Furthermore, the power box is a battery box. There is a battery and a battery charger as power sources inside the battery box. A battery power-off switch and a power quantity display are arranged on the side of the battery box body; the drive wheel drive device includes a traveling motor and a speed reducer. The power state of the whole machine can be controlled through the battery power-off switch, and the operator can obtain the battery power information from the power quantity display for timely charging.

[0009] Furthermore, a seat is installed on the power box. One end of the seat is connected to the power box through a hinge, and the other end is connected to the power box through a buckle. Armrests are arranged on the left and right sides of the seat, and a control panel is arranged on any one of the armrests. By opening the buckle, the seat can be lifted forward to charge or replace the battery.

[0010] Furthermore, an armrest mechanism is also arranged at the rear end of the vehicle body. The armrest mechanism includes an angle adjustment mechanism, a swing rod, and a handle. The angle adjustment mechanism is installed on the swing rod and can adjust the angle of the swing rod. The handle is installed at the end of the swing rod. The angle adjustment mechanism includes an angle adjustment rod, an angle clamping shaft, and a rotating chuck fixed to the rear of the vehicle body. The swing rod is connected to the rotating chuck through a rotating shaft. The angle adjustment rod is connected to the rotating shaft arranged on the swing rod through a connecting rod. The angle clamping shaft is connected to the angle adjustment rod through a connecting rod. The two ends of the angle clamping shaft cooperate with the teeth on the rotating chuck. Pulling up the angle adjustment rod will unlock the angle clamping shaft from the rotating chuck. Then, the swing rod can be adjusted to a suitable angle by lifting or pressing down the handle. Finally, pulling down the angle adjustment rod, the angle clamping shaft is clamped into the teeth on the rotating chuck to complete the locking.

[0011] Furthermore, an electric control box is also installed at the rear end of the vehicle body. The electric control box is electrically connected to the drive wheel drive device, the power source, and the lifting drive device.

[0012] As can be seen from the above technical solutions, the present utility model has the following beneficial effects:

[0013] 1. The high-efficiency self-migrating grinding machine provided by the present utility model raises the head part through a guide wheel lifting mechanism. It is equipped with an independent power source and can move by itself without external power supply. Each driving wheel has a separate driving wheel driving device, and the overall flexible steering can be achieved by driving a single driving wheel and cooperating with universal wheels. Generally, the grinding machine can move without electricity by itself.

[0014] 2. The present utility model adds a guide wheel lifting mechanism at the head part, which can lift the head and use a relatively small downward pressure to lift the entire grinding mechanism off the ground, facilitating the replacement of the grinding disc and improving work efficiency.
