Description

Technical Field

[0001] The utility model relates to the technical field of laser leveling machines, in particular to a telescopic arm type concrete laser leveling machine. Background Art

[0002] When laying concrete, after pouring concrete in the construction area, it must be leveled before the concrete hardens to make the surface of the hardened concrete flat. At this time, a concrete leveler is needed. During the construction project, the ground needs to be compacted manually, and then the concrete mixture is poured into the construction site through equipment, and then the concrete mixture is spread manually until it is relatively flat, and finally the leveler is used to vibrate and compact it.

[0003] In the prior art, a Chinese utility model patent document with publication number CN208869918U provides a concrete paving and leveling machine for road and bridge construction that is able to prevent material from getting stuck. The leveling mechanism of the leveling machine fills potholes with concrete mixture by providing a filling device, and levelizes bulges on the concrete ground by providing a scraper. The vibration motor can drive the vibration plate to compact and level the concrete paving surface. Compared with traditional leveling machines with a single function, the utility model has three working steps of filling, leveling and leveling at the same time, avoiding material jamming during filling and time-consuming leveling, greatly reducing labor intensity, shortening construction time, and improving work efficiency.

[0004] Generally speaking, when scraping concrete that is higher than the floor level, the following is followed: Figure 8 As shown in the figure, the scraper scrapes the concrete pile in the direction of the arrow. The concrete pile is spread forward and to both sides at the same time under the scraping action of the scraper, and finally flattened to achieve a leveling effect; when the concrete pile is high, the following will appear Fig. 9 In the situation shown in Figure 9, when the concrete pile is spread forward to both sides under the scraping action of the scraper, more concrete will leak from both sides. In the actual operation, in order to shorten the moving distance of the leveling machine, the leveling machine is generally leveled gradually from one side of the site to the other side. Therefore, in order to avoid the leveling machine reversing back and forth, the leveling machine will adopt the following method Fig.10 The operation method shown utilizes half of the scraper to scrape the concrete pile to avoid backing up. However, such operation significantly reduces the utilization rate of the scraper, which is not conducive to improving the operation efficiency.

[0005] However, the disadvantage of the utility model is that the scraper thereof belongs to the conventional scraper structure in the leveling machine, which is mainly used for leveling slightly raised concrete piles with a small difference between the height and the floor elevation. This scraper is not suitable for the higher concrete piles generated when pouring from the concrete tank truck. Fig. 9 The leveling effect of the concrete pile shown is still average and needs improvement. Utility Model Content

[0006] The utility model aims to solve the problem that the scraper of the concrete spreading and leveling machine in the prior art has a general effect when leveling a high pile of concrete, and proposes a telescopic arm concrete laser leveling machine.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A telescopic arm concrete laser leveler comprises a vehicle body, a concrete tank is arranged at the rear end of the vehicle body, a control system and a telescopic arm are arranged at the front end of the vehicle body, a lifting rod is arranged at the working end of the telescopic arm, a leveling mechanism is arranged at the bottom end of the lifting rod, the leveling mechanism comprises a vibrating plate, a scraper and a filling device, a conveying pipe is arranged between the concrete tank and the filling device, a depth scraping device is arranged at the middle position of the filling device away from the scraper, the depth scraping device comprises a fixing seat fixed on the filling device, a scraper plate is arranged inside the fixing seat, and a hydraulic cylinder for pushing the scraper plate downward is arranged at the top of the fixing seat;

[0009] The control system includes a laser transmitter and a control box, and the control box is electrically connected with the telescopic arm, the lifting rod, the leveling mechanism, the filling device, and the hydraulic cylinder.

[0010] Furthermore, a guide groove opening downward and toward the vehicle body is provided inside the fixing seat, and the scraper plate is located inside the guide groove.

[0011] Furthermore, the cross-sections of the scraper plate and the guide groove are both U-shaped, the concave surfaces of the scraper plate and the guide groove face the vehicle body, and the outer wall of the scraper plate fits with the inner wall of the guide groove.

[0012] Furthermore, the delivery pipe comprises a delivery steel pipe installed on the vehicle body, one end of the delivery steel pipe is connected to the concrete tank, and the other end is connected to one end of a delivery hose. A delivery pump is installed on the delivery steel pipe, and the other end of the delivery hose leads to a filling device.

[0013] Furthermore, the telescopic arm includes a first single arm extending from the telescopic base and a second single arm extending from the first single arm. A connecting seat is provided at one end of the first single arm close to the second single arm.

When encountering an ordinary slightly raised concrete pile, the scraper is used to level it. When encountering a position where filler is required, the concrete in the concrete tank is filled to this position through the filling device. When encountering a concrete pile with a higher raised height, the hydraulic cylinder is started to drive the scraper plate to descend to a position where the bottom end of the scraper plate is lower than the scraper plate, and then the telescopic arm is controlled to retract, driving the scraper plate to first scrape more concrete in the middle of the high concrete pile, so that the concrete surface at the position scraped by the scraper plate is lower than the concrete surfaces on both sides of the scraper plate, forming a concave area. Then, when the scraper plate performs secondary leveling on this position, the concrete exceeding the floor elevation flows to the concave area under the scraping action of the scraper plate, thereby leveling the higher raised concrete pile at one time. Compared with the prior art, the action of reversing and turning back to level again can be effectively avoided, thereby improving the concrete leveling efficiency.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Reference Figure 1-10 The utility model telescopic arm concrete laser leveling machine comprises a vehicle body 1, wheels and legs are installed around the vehicle body 1 to support the vehicle body and keep balance, a concrete tank 2 is arranged at the rear end of the vehicle body 1, and a filling port is arranged at the top of the concrete tank 2;

[0033] The front end of the vehicle body 1 is provided with a control system 4 and a telescopic arm 9. The control system 4 controls the leveling machine and is electrically connected with the telescopic arm 9, the lifting rod 12, the leveling mechanism, and the conveying pump 3. The working end of the telescopic arm 9 is provided with a lifting rod 12. The bottom end of the lifting rod 12 is provided with a leveling mechanism 13. The leveling mechanism 13 includes a vibration plate 1301, a scraper 14, and a filling device 15. A conveying pipe is provided between the concrete tank 2 and the filling device 15. A deep scraping device 18 is provided at the middle position of the filling device 15 away from the scraper 14. The deep scraping device 18 includes a fixed seat 21 fixed on the filling device 15. A scraper plate 22 is provided inside the fixed seat 21. A hydraulic cylinder 17 for pushing the scraper plate 22 downward is provided on the top of the fixed seat 21.

[0034] The control system 4 includes a laser transmitter (not shown in the figure) and a control box, and the control box is electrically connected to the telescopic arm 9, the lifting rod 12, the leveling mechanism 13, the filling device 15, and the hydraulic cylinder 17.

[0035] During each leveling, the leveling mechanism 13 is first raised to a position exceeding the height of the concrete pile through the lifting rod 12, and then the telescopic arm 9 is controlled to extend to the side of the concrete pile away from the leveling machine, and then the leveling mechanism 13 is adjusted to descend to the floor elevation position according to the laser signal of the laser transmitter, and finally the telescopic arm 9 is controlled to retract, driving the leveling mechanism 13 to level the concrete. During leveling, the scraper 14 scrapes the concrete surface flat, and the vibration plate 1301 vibrates the concrete surface to further level the concrete.

[0036] A guide groove 23 opening downward and toward the vehicle body 1 is provided inside the fixing seat 21 , and the scraper plate 22 is located inside the guide groove 23 .

[0037] The guide groove 23 provides a guiding function for the scraper plate 22 to move up and down, thereby improving the running stability of the scraper plate 22 .

[0038] The cross sections of the scraper plate 22 and the guide groove 23 are both U-shaped, the concave surfaces of the scraper plate 22 and the guide groove 23 face the vehicle body 1 , and the outer wall of the scraper plate 22 fits with the inner wall of the guide groove 23 .

[0039] Since concrete tends to flow to both sides when it is scraped from the middle of the concrete pile, the U-shaped scraper plate 22 can scrape more concrete toward the side close to the vehicle body 1 and reduce its movement to both sides, thereby preventing the concrete from flowing toward the concrete surface on the side that has been leveled.

[0040] The delivery pipe includes a delivery steel pipe 8 installed on the vehicle body 1 , one end of the delivery steel pipe 8 is connected to the concrete tank 2 , and the other end is connected to one end of a delivery hose 11 . A delivery pump 3 is installed on the delivery steel pipe 8 , and the other end of the delivery hose 11 leads to a filling device 15 .

[0041] When filling at a location where filling is required, the delivery pump 3 is started to deliver the concrete in the concrete tank 2 to the location through the delivery steel pipe 8 and the delivery hose 11, and the concrete is poured into the location through the filling device 15 to complete the filling operation.

[0042] The telescopic arm 9 includes a first single arm 5 extending from the telescopic base and a second single arm 7 extending from the first single arm 5. A connecting seat 6 is provided at one end of the first single arm 5 close to the second single arm 7. A lifting ring 10 is connected below the connecting seat 6. The lifting ring 10 is fixedly connected to a conveying hose 11.

[0043] The conveying hose 11 is mainly used to cooperate with the telescopic arm 9 to complete the telescopic action. At the same time, in order to prevent the middle part of the conveying hose 11 from sagging to the ground and being worn when the telescopic arm 9 is retracted, the middle position of the conveying hose 11 is adjusted by the lifting ring 10 to prevent the middle part of the conveying hose 11 from sagging to the ground.

[0044] The filling device 15 includes a filling groove with an opening at the top, a filling hole 19 is arranged in the filling groove, an auger motor 16 connected to the auger 20 is arranged at the end of the filling groove, the working end of the auger motor 16 is connected to the auger 20, the filling groove is located below the auger 20 and is provided with a filling hole 19, and the depth scraping device 18 is fixedly connected to the outer wall of the filling groove.

[0045] When filling is needed, the delivery pump 3 and the auger 20 are started, and the concrete material is pumped into the filling tank through the delivery pipe, and flows from the filling hole 19 to the area where filling is needed under the stirring action of the auger.

[0046] The bottom end of the scraper plate 22 is higher than the bottom end of the filling device 15 .

[0047] During the normal scraping process, the scraper plate 22 does not participate in the scraping, and the scraper plate 14 can scrape normally. When scraping a high concrete pile, the deep scraping device 18 is started, and the scraper plate 22 is lowered to a position below the filling device 15 for auxiliary scraping.

[0048] The deep scraper 18 is installed on the filling device 15 instead of on the scraper 14. The reason is that if it is installed on the scraper 14, each time the deep scraper 18 is started, the scraper plate 22 and the scraper 14 work synchronously, and the concrete scraped by the scraper 14 is not easy to fill the depressions scraped by the scraper plate 22. However, if it is installed on the filling device 15, since the filling device 15 is separated from the deep scraper 18 and the scraper 14, the concrete scraped by the scraper 14 will automatically flow to both sides and the front, that is, a part of the concrete will flow to the middle and front. When this part of the concrete flows forward for a distance equivalent to the width of the filling device 15, it can be better gathered in the middle of the scraper 14. At this time, it can also flow into the depression better to fill the depression and achieve a leveling effect.

[0049] Working principle: When in use, the vehicle body 1 is parked at one side of the working area, the control system 4 adjusts the telescopic arm 9 to drive the lifting rod 12, adjusts the position of the leveling mechanism 13 to the side of the working area away from the vehicle body 1, adjusts the height of the leveling mechanism 13 according to the signal of the laser generator, and then drives the leveling mechanism to level the concrete surface by retracting the telescopic arm 9;

[0050] When encountering a common slightly raised concrete pile, use the scraper 14 to flatten it, and when encountering a position where filling is required, fill the concrete in the concrete tank 2 to the position through the filling device 15;

[0051] When encountering a concrete pile with a higher bulge height, the hydraulic cylinder 17 is started to drive the scraper plate 22 to descend to a position where the bottom end of the scraper plate 22 is lower than the scraper plate 14, and then the telescopic arm 9 is controlled to retract, driving the scraper plate 22 to first scrape more concrete in the middle of the high concrete pile, so that the concrete surface at the position scraped by the scraper plate 22 is lower than the concrete surfaces on both sides of the scraper plate 22, forming a depression. At the same time, when the scraper plate 22 scrapes to this position, the position is scraped twice. When the concrete exceeding the floor elevation automatically flows to the sides and the front under the scraping action of the scraper plate 14, a part of the concrete near the middle position flows to the depression. When the scraping position of the scraper plate 22 exceeds the higher position of the concrete pile, the hydraulic cylinder 17 is controlled to drive the scraper plate 22 to rise, and continue to perform normal scraping through the scraper plate 14, thereby scraping the higher concrete pile at one time.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
