Description

Technical Field

[0001] The utility model relates to the technical field of grinders, and particularly relates to a floor grinder with a control handle. Background Art

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

[0003] When traditional grinders are used for site grinding, they rely on manual force to control the machine back and forth, left and right. The labor intensity is large, and the force of manual turning and pushing is not uniform, which will cause some bottoms to be over-ground and some floors to be under-ground, thus affecting the grinding effect. Content of the Utility Model

[0004] Purpose of the utility model: In order to overcome the above deficiencies, the purpose of the utility model is to provide a guide wheel lifting mechanism for a floor grinder, which has a simple structure and reasonable design. After adding a control handle, there is no need for manual labor, and only the direction switch needs to be controlled, which completely reduces the labor intensity and creates an easy working environment for workers.

[0005] Technical solution: In order to achieve the above purpose, the utility model provides a floor grinder with a control handle, which includes a vehicle body, a grinding disc, a driving mechanism and a control handle. The grinding disc is installed at the front end of the vehicle body, the driving mechanism is arranged at the lower part of the vehicle body, the control handle is installed at the end of the vehicle body, and the control handle is connected to the grinding disc and the driving mechanism through a control wire harness. A control handle is added to the grinder. Workers can control the movement and direction of the grinder through the control handle, and at the same time can also control the operation of the grinding disc, greatly reducing the labor intensity of workers, and at the same time ensuring the grinding effect.

[0006] Further, the control handle includes a swing arm, a control panel and a handrail. The swing arm is rotatably installed at the end of the vehicle body, the control panel is installed on the swing arm, the handrail is arranged at the end of the swing arm, and a steering switch is arranged on the handrail. If you want to turn the vehicle body, just press the corresponding steering switch on the handrail.

[0007] Furthermore, an angle adjustment mechanism is provided on the swing arm. The angle adjustment mechanism includes a toothed disc, a pull rod, and a clamping shaft. The toothed disc is fixedly provided on the vehicle body. The swing arm is connected to the toothed disc through a rotating shaft. The pull rod is connected to the clamping shaft through a connecting rod. The clamping shaft engages with the teeth on the toothed disc. A reset device is provided on the connecting rod, and the reset device is a spring sleeved on the connecting rod. Pull up the pull rod to disengage the clamping shaft from the teeth of the toothed disc. Manually rotate the swing arm to an appropriate angle and then release the pull rod. Under the action of the spring, the clamping shaft resets and engages with the teeth of the toothed disc.

[0008] Furthermore, a function key area is provided on the control panel. The function key area includes a grinding disc speed control knob, a grinding disc start switch, a traveling speed control knob, a motor forward and reverse button, a power indicator light, an emergency stop / remote control switch, and a fault indicator light, and also includes a control line connector. Slowly rotate the grinding disc speed control knob to increase the rotational speed of the grinding motor to the corresponding working speed; slowly rotate the traveling speed control knob to increase the motor speed to the corresponding traveling speed; select the traveling direction (forward and backward) of the vehicle body through the motor forward and reverse button; after connecting the power cord, the power indicator light will light up; when starting the equipment, first turn on the emergency stop / remote control switch; when stopping the equipment, turn off and reset all switches and finally turn off the emergency stop / remote control switch; when the equipment is running, in case of an emergency, press the emergency stop / remote control switch to cut off the power supply of the equipment to protect the safety of personnel and equipment. When switching to remote control, also press the emergency stop / remote control switch and turn on the emergency stop switch on the remote control at the same time to achieve switching to remote control.

[0009] Furthermore, a grinding motor is provided on the grinding disc. The grinding motor is connected to the grinding disc through a gearbox. A dust suction pipe interface is also provided on the grinding disc.

[0010] Furthermore, a foldable guide wheel is provided at the front end of the vehicle body, a tool box and a battery box are provided in the middle of the vehicle body, and a rotatable foot pedal rod is provided at the rear end of the vehicle body. When the vehicle body is relocated and maintained, the worker can use the lever principle to lift the grinding disc by stepping on the foot pedal rod, and then lower the guide wheel during relocation.

[0011] Furthermore, the driving mechanism includes a set of driving wheels, and each driving wheel is connected to a driving motor.

[0012] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0013] The present utility model is provided with a control handle on the grinding machine. By pressing the function buttons on the control panel of the control handle, it is possible to control the forward and backward movement of the vehicle body, the start and stop of the grinding disc, and the rotational speed. The steering of the vehicle body is controlled through the steering switch on the armrest. Compared with the traditional grinding machine, the physical labor intensity is reduced, and a relaxed working environment is created for the workers. Description of the Drawings
