Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a building construction mechanical equipment and an operating method. Background Art

[0002] In the field of construction, floor polishing is an important process to ensure that the floor is flat and smooth. It is widely used in the floor treatment of various materials such as concrete, stone, and ceramic tiles. In the traditional floor polishing process, a large amount of cooling water is usually required to reduce the heat generated during the polishing process, prevent the equipment from overheating, and protect the floor from high temperature damage.

[0003] However, when using the equipment to polish the floor, the cooling water cools down the grinding wheel, and the cooling water mixes with the dust particles from the floor polishing and remains on the ground. The sewage remaining on the ground will cover the polished floor, causing the sewage to block the polished floor, which in turn affects the operator's observation of the polished floor, making it difficult for them to directly observe the actual effect of the floor polishing. They need to use additional tools to clean the cooling water on the ground in order to observe the floor polishing effect, and it increases the burden of subsequent cleaning work.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a construction machinery and equipment having the following beneficial effects:

[0024] 1. The construction machinery and equipment can manually rotate the steering wheel, and the steering wheel can drive the long shaft and the small gear thereon to rotate. When the small gear rotates, it can drive the large gear and the arc-shaped wiper on the first gear shaft to rotate. When the arc-shaped wiper rotates to the left, it can guide the cooling water remaining on the ground to the left, so that the cooling water can flow to the left side. At this time, the operator can clearly observe the condition of the ground after grinding, which improves the construction efficiency and avoids the problem in the traditional method that the operator needs to use tools to clean the cooling water on the ground after grinding the ground in order to observe the grinding effect of the ground.

[0025] 2. The construction machinery equipment is moved forward by the operator's hand-held support frame, which enables the support frame to move forward under the action of the crawler wheels and crawler tracks, thereby controlling the sand disc to gradually move forward and evenly grinding the ground. This avoids the problem that when the wheels are used in the traditional way to move on the unpolished ground, the wheels in contact with the ground are prone to frequent bumps during movement due to the small contact area with the ground, which leads to the problem of uneven ground after grinding. The fixed crawler type travel mode, due to its increased contact area with the ground, makes the equipment move more smoothly, thereby indirectly improving the grinding quality of the ground.

[0026] 3. This construction machinery equipment, by starting the motor, the output shaft of the motor can drive the sand disc to rotate, at this time, start the water pump through the control panel, the water pump will transport the cooling water in the water tank to the annular water outlet pipe, and finally flow out from the multiple water outlets of the annular water outlet pipe to the sand disc, and finally flow into the position where the sand disc contacts the ground for grinding through the water inlet groove on the sand disc, which can make the position where the sand disc contacts the ground to be effectively cooled and polished, which not only improves the grinding efficiency, but also avoids the traditional method where the cooling water is not easy to act on the grinding surface, thereby resulting in the ground grinding not being effectively cooled and causing the equipment service life to be reduced.

[0027] 4. The construction machinery and equipment starts the second push rod through the control panel. The second push rod can drive the first fixed plate and the components thereon to rotate a certain angle with the axis of the fixed column as the center of the circle through the fixed seat, so that the sand disc can be adjusted to a suitable grinding angle, which can make the ground be ground more smoothly to adapt to different ground surfaces.

The water pump 15 is fixedly installed on the first fixed plate 1, and the water tank 16 is fixedly installed on the first fixed plate 1, and the input end of the water pump 15 is connected to the water tank 16.

[0044] Furthermore, the output end of the water pump 15 is connected to the annular water outlet pipe 14 , the first push rod 13 is fixedly mounted on the lower surface of the optical axis fixing plate 8 , the output end of the first push rod 13 is fixedly connected to the motor 11 , and a second fixing plate 17 is fixedly connected between the two side frames 3 .

[0045] Furthermore, the second fixed plate 17 is rotatably connected to the first gear shaft 18, the arc-shaped wiper blade 19 is fixedly connected to the lower end of the first gear shaft 18, the upper end of the first gear shaft 18 is fixedly sleeved with a large gear 20, the two support frames 6 are fixedly connected to an upper fixed plate 25, and a control panel is fixedly installed on the upper fixed plate 25.

[0046] Furthermore, a long shaft 21 is rotatably connected between the upper fixed plate 25 and the second fixed plate 17, a small gear 22 is fixedly sleeved on the lower end of the long shaft 21, the small gear 22 is meshedly connected with the large gear 20, and the upper end of the long shaft 21 rotates through the upper surface of the upper fixed plate 25 and is fixedly sleeved with a steering wheel 26.

[0047] Furthermore, a fixing seat 23 is fixedly connected to one side of the first fixing plate 1 , and a second push rod 24 is disposed on a lower surface of the upper fixing plate 25 . An output end of the second push rod 24 is rotatably connected to the fixing seat 23 .

[0048] Furthermore, when in use, by starting the motor 11, the output shaft of the motor 11 can drive the sand disc 12 to rotate, and at this time, the water pump 15 is started through the control panel, and the water pump 15 will transport the cooling water in the water tank 16 to the annular water outlet pipe 14, and finally flow out from the multiple water outlets of the annular water outlet pipe 14 to the sand disc 12, and finally flow through the water inlet groove on the sand disc 12 to the position where the sand disc 12 contacts the ground for grinding. This can enable the position where the sand disc 12 contacts the ground to be effectively cooled and polished, which not only improves the grinding efficiency, but also avoids the situation in which the cooling water is not easy to act on the grinding surface in the traditional way, thereby resulting in the reduction of equipment service life due to the ineffective cooling of the ground grinding.

[0049] Furthermore, after the motor 11 is started, the second push rod 24 is started through the control panel. The second push rod 24 can drive the first fixed plate 1 and the components thereon to rotate a certain angle with the axis of the fixed column 2 as the center through the fixed seat 23, so that the sand disc 12 can be adjusted to a suitable grinding angle, which can enable the ground to be polished more smoothly to adapt to different ground surfaces.

[0051] Furthermore, the operator moves the support frame 6 forward by hand, which enables the support frame 6 to move forward under the action of the crawler wheel 4 and the crawler track 5, thereby controlling the sand disc 12 to gradually move forward and evenly grind the ground. This avoids the problem that when the wheels are used to move on the unpolished ground in the traditional way, the wheels in contact with the ground are prone to frequent bumps during movement due to the small contact area with the ground, thereby causing the ground to be uneven after grinding. The fixed crawler type of movement mode, due to its increased contact area with the ground, makes the movement of the equipment more stable, thereby indirectly improving the grinding quality of the ground.

[0052] Furthermore, when the sand disc 12 moves forward to grind the ground, by manually rotating the steering wheel 26, the steering wheel 26 can drive the long shaft 21 and the small gear 22 thereon to rotate. When the small gear 22 rotates, it can drive the large gear 20 and the arc-shaped wiper 19 on the first gear shaft 18 to rotate. When the arc-shaped wiper 19 rotates to the left, the cooling water remaining on the ground can be guided to the left so that the cooling water can flow to the left side.

[0060] Furthermore, after the motor 11 is started, the second push rod 24 is started through the control panel. The second push rod 24 can drive the first fixed plate 1 and the components thereon to rotate a certain angle with the axis of the fixed column 2 as the center through the fixed seat 23, so that the sand disc 12 can be adjusted to a suitable grinding angle.
