Description

A high-safety troweling machine for municipal road construction

technical field

The invention belongs to the technical field of road administration tools, in particular to a high-safety trowel for municipal road construction.

Background technique

The troweling machine is also called a finishing machine. Its main structure is a gasoline engine-driven spatula rotor, and a spatula is installed on the bottom of the cross in the middle of the rotor. The inclination direction of the spatula is consistent with the rotation direction of the rotor, and the V-belt is driven by the gasoline engine to make the rotor of the spatula rotate. When operating, start the fire first and hold the control handle. Compared with manual polishing, the work efficiency can be improved by more than 30 times.

Existing trowels lack protective devices. Once they are out of hand and out of control during use, they will start to rotate and it is difficult to force them to stop, which is prone to self-rotation and injury and cause accidents.

working principle:

When the trowel is started, the engine 16 rotates, driving the connected power rod 17 to rotate, because the power rod 17 is covered with the first transmission ring 18, so it drives the first transmission ring 18 to rotate, and drives the first transmission ring 18 under the action of the transmission belt 19. The second transmission ring 21 rotates. At this time, the handle 8 is pressed to drive the connected handle 5 and the L-shaped pressure block 39 to press down, so that the pressure applying column 25 sinks and offsets the pressure plate 32, so that the pressure plate 32 is pressed down and connected with the pressure plate 32. The transmission shaft 14 sinks, so the bevel gear 15 at the upper end of the transmission shaft 14 can form power transmission with the second transmission shaft 20 on one side extending into the fixed bevel gear 41 on the end surface of the second casing 30 . Simultaneously, the downward pressure of the pressing plate 32 will compress the first spring 13 at the lower end, and the first spring 13 will pass the pressure to the fixing ring 27 at the lower end, so that the chassis cover 2 will sink to play a protective role.

At this time, due to the downward pressure of the pressing plate 32, the movable sleeve 34 sinks, and the distance from the chassis cover 2 is reduced, which drives the movable connecting rod 7 around the movable sleeve to press down and rotate, and the slider 42 on the top of the chassis cover 2 is pushed outward, resulting in sliding. The hydraulic oil in the hydraulic tank is squeezed into the outer end close to the chassis cover 2, so that the inner sliding rod 46 is retracted, and the protection of the spatula 10 is canceled.

When the hand leaves the handle 8 or forgets to turn off the engine 16 to cause no one to control the trowel, due to the lack of downward force, the second spring 35 and the first spring 13 bounce up, pushing the pressure plate 32 to rise, and at the same time, the drive shaft 14 is lifted. When disengaged, the bottom spatula no longer works for added safety. At the same time, due to the rise of the pressing plate 32, the distance between the movable sleeve 34 increases, and the movable rod 7 around the movable sleeve is lifted and rotated to pull the slider 42 back, and at the same time, the hydraulic oil in the sliding hydraulic tank is withdrawn, so that the internal sliding rod 46 is stretched out. Play spatula 10 protective effect.

The effect of the button block 9 on the handle is that the power failure for no reason can be temporarily used for starting the engine 16 when the trowel is in use.

The above description is only an embodiment of the present invention, and does not limit the scope of patent protection of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related All technical fields are equally included in the scope of patent protection of the present invention.
