Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete floor leveling machine for building construction. Background Art

[0002] Concrete floor leveling machines are widely used in paving and leveling concrete surface layers in high-grade highways, municipal roads, airport runways, water conservancy projects, slopes and other projects. Due to the large area, thick surface protection layer, high surface flatness requirements, special surface treatment requirements, and the requirement to be completed in one go, the production process has high requirements.

[0003] Patent announcement number CN202010939781.6 discloses a concrete floor leveling machine, which discloses a technical solution for leveling the ground by cooperating with a double-ring roller groove and a sinker column block, and by using the sinker column block to counterweight the outer sleeve ring groove and roller to deposit the weight angle on the concrete floor base and the inner cement ring edge when the inner wheel ring groove rotates.

[0004] However, the concrete floor leveling machine used in the above-mentioned prior art can only level the shallow layer of the ground. The local vibration of the submerged column blocks causes the concrete floor to have undulations and protrusions of varying heights. The inertial vibration makes it difficult to flatten the height difference of the concrete, affecting the flatness of the ground.

[0005] Based on this, it is necessary to design a leveling rod vibrating concrete floor leveling machine for construction, which can improve the homogeneity of concrete and the safety factor of the ground after the concrete is thick and solidified, and effectively improve the efficiency of equipment use and the accuracy of leveling. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a concrete floor leveling machine for construction, and the specific technical scheme is as follows:

[0007] A concrete floor leveling machine for construction includes a leveling machine body and a leveling roller. The leveling machine body is provided with a supporting power mechanism for driving the leveling roller to roll on the ground. The leveling roller is hollow. A rotating shaft is movably provided at the axis of the inner wall of the leveling roller. A plurality of vibration mechanisms for knocking the leveling roller to vibrate are fixedly provided on the periphery of the rotating shaft. Arc-shaped shock-pressure plates are fixedly provided on the top and bottom surfaces of the inner wall of the leveling roller, and the ends of the vibration mechanisms elastically knock the shock-pressure plates.

[0008] As an improvement of the technical solution, the supporting power mechanism includes a connecting rod and a supporting plate, the top of the leveling locomotive body is fixedly provided with a connecting rod, and the other end of the connecting rod is fixedly provided with a supporting plate.

[0009] As an improvement of the technical solution, electric push rods are fixedly provided on both sides of the support plate, and a scraper that contacts the ground is fixedly installed on the bottom of the electric push rod.

[0010] As an improvement of the technical solution, the vibration mechanism includes a counterweight, a spring, a limit rod and a limit sleeve. The rotating shaft is fixedly sleeved with a limit sleeve on the periphery. Several groups of springs are distributed in a ring around the outer periphery of the limit sleeve. A counterweight is fixedly provided at the other end of the spring. A limit rod fixedly connected to the counterweight is slidably inserted into the limit sleeve.

[0011] As an improvement of the technical solution, the bottom surface of the leveling locomotive body is provided with multiple sets of running wheels.

[0012] Beneficial effects of the utility model:

[0013] 1. The vibration mechanism inside the leveling roller is rotated to drive the vibration mechanism through the rotating shaft. The lower vibration mechanism and the upper vibration mechanism knock the vibration plate and then knock the leveling roller, so as to achieve uniform vibration of the ground up and down to strengthen the leveling work and improve the leveling efficiency. The paved concrete is quickly compacted and vibrated, and the above process is repeated, which greatly improves the quality of concrete paving, reduces the occurrence of potholes on the ground caused by uneven paving, and improves the compressive safety factor of the ground after the concrete solidifies. The utility model is a mechanical leveling machine with simple operation, large working area and high leveling efficiency.

[0014] 2. The utility model drives the leveling roller to push the accumulated concrete forward through the motor drive and the electric push rod, and cooperates with the subsequent leveling process inside the leveling roller to make the concrete floor deeply leveled. The scrapers on both sides of the leveling roller level the accumulated concrete on both sides, improving the uniformity of deep-level pressing, covering and sliding.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See attached Figure 1 -Attached Figure 4 ,in, Figure 1 A three-dimensional diagram of a concrete floor leveling machine for construction; Figure 2 A cross-sectional view of a concrete floor leveling machine for construction; Figure 3 A side sectional view of a leveling roller in a concrete floor leveling machine for construction; Figure 4 It is a three-dimensional diagram of a vibration-pressure plate 23 in a concrete floor leveling machine for construction.

[0022] The leveling machine used in the prior art can only level the shallow layer of the concrete floor, and the density of the concrete blocks on both sides of the leveling machine is different from that in the middle, resulting in low flatness of the concrete surface.

[0023] In order to solve the above technical problems, a concrete floor leveling machine for construction is provided, which comprises a leveling machine body 1 and a leveling roller 2. The leveling machine body 1 is provided with a supporting power mechanism for driving the leveling roller 2 to roll on the ground.

[0024] The leveling roller 2 is displaced in the front-rear horizontal direction by driving the leveling locomotive body 1, and the rotating shaft 21 is driven to rotate by the supporting power mechanism, so that the leveling roller 2 is close to the concrete layer to level the concrete layer.

[0025] The leveling roller 2 is in a hollow state, and a rotating shaft 21 is movably arranged at the axis of the inner wall of the leveling roller 2, and multiple groups of vibration mechanisms 3 for knocking the leveling roller 2 to vibrate are fixedly arranged on the periphery of the rotating shaft 21;

[0026] By driving a fixed vibration mechanism 3 on the rotating shaft 21, and the vibration mechanism 3 has multiple groups and is staggered up and down, the vibration mechanism 3 is rotated and knocked on the upper and lower sides of the track to form a continuous vibration on the leveling roller 2, so as to deeply level the soil blocks in the concrete layer, make the concrete floor height consistent and make the mud evenly paved.

[0027] Arc-shaped shock-pressure plates 23 are fixedly provided on the top and bottom surfaces of the inner wall of the leveling roller 2 , and the end of the vibration mechanism 3 elastically strikes the shock-pressure plates 23 .

[0028] When the rotating shaft 21 rotates, the top surface of the vibration mechanism 3 on the upper part of the rotating shaft 21 hits the surface of the top shock plate 23, and the bottom surface of the vibration mechanism 3 on the lower part of the rotating shaft 21 hits the surface of the ground shock plate 23. The vibration mechanism 3 hits the shock plate 23 back and forth, thereby increasing the vibration frequency.

[0029] The supporting power mechanism comprises a connecting rod 12 and a supporting plate 13 . The connecting rod 12 is fixedly provided on the top of the leveling locomotive body 1 , and the supporting plate 13 is fixedly provided on the other end of the connecting rod 12 .

[0030] The connecting rod 12 and the supporting plate 13 can enhance the left-right stability of the leveling roller 2, thereby improving the leveling efficiency while ensuring the flatness.

[0031] Electric push rods 14 are fixedly mounted on both sides of the support plate 13 , and scrapers 22 that come into contact with the ground are fixedly mounted on the bottom of the electric push rods 14 .

[0032] The leveling distance can be controlled by adjusting the length of the electric push rod 14, and the connecting rod 12 drives the electric push rod 14 to rotate synchronously to adjust the height of the leveling roller 2. In this process, the concrete on both sides contacts the arched surface of the scraper 22, and the arc structure of the scraper 22 makes the surface smooth enough during the leveling, so that the concrete stacked on both sides during the concrete leveling is spread and flat, thereby improving the utilization rate of concrete materials and the flatness of the leveled ground.

[0033] The vibration mechanism 3 includes a counterweight 31, a spring 32, a limit rod 33 and a limit sleeve 34. The limit sleeve 34 is fixedly sleeved on the outer periphery of the rotating shaft 21. Several groups of springs 32 are distributed in an annular manner on the outer periphery of the limit sleeve 34. The other end of the spring 32 is fixedly provided with a counterweight 31. A limit rod 33 fixedly connected to the counterweight 31 is slidably inserted into the limit sleeve 34.

[0034] The counterweight 31, spring 32 and limit rod 33 rotate in coordination with the rotating shaft 21, and the gravity of the counterweight 31 drives the spring 32 to move vertically back and forth along the limit rod 33, and the elastic restoring force of the spring 32 drives the counterweight 31 to quickly strike the counterweight 31 shock plate 23. The surface of the leveling roller 2 will be impacted by the shock plate 23, and the indirect vibration and knocking prevents the surface of the leveling roller from knocking up and down on the damaged surface.

[0035] The bottom surface of the leveling locomotive body 1 is provided with a plurality of sets of running wheels 15 .

[0036] The front-rear displacement direction of the leveling vehicle body 1 can be controlled by the running wheels 15 .

[0037] The working principle and use process of the utility model are as follows: when in use, the locomotive body 1 to be leveled drives the leveling roller 2 to rotate, and the spring 32 of the vibration mechanism 3 inside the leveling roller 2 is used to vibrate and roll to level the ground; at this time, the concrete accumulated on both sides of the ground after rolling is leveled by the scraper 22.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
