Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an engineering concrete leveling device. Background Technology

[0002] In the field of construction engineering, concrete leveling is a key process to ensure the flatness of concrete structure surfaces and meet the requirements of subsequent construction and use performance. Traditional concrete leveling mainly relies on manual operation, with manual use of tools such as scrapers and trowels. This requires the cooperation of many people and is slow, making it difficult to meet the schedule requirements of large-scale projects. As the construction industry develops towards industrialization, precision, and intelligence, the requirements for the quality and efficiency of concrete construction are constantly increasing, which has promoted the research and development and application of engineering concrete leveling devices.

[0003] However, the applicant believes that the existing concrete leveling device has the following shortcomings: 1. The device width is fixed and cannot be adjusted according to the road width, resulting in poor applicability when facing construction roads of different widths; 2. During leveling, because the connection between the trowel and the device cannot be moved, even a small lateral movement requires moving the entire device, resulting in a large overall volume and weight. This not only consumes more manpower during the movement but also easily damages the leveled area; 3. The fixed connection between the trowel and the device makes cleaning the trowel after use troublesome and difficult to thoroughly clean. Concrete residue will remain on the surface of the trowel during the leveling process, and long-term accumulation will affect the flatness of the trowel, thereby reducing the accuracy of subsequent leveling.

[0004] Therefore, we propose an engineering concrete leveling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an engineering concrete leveling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering concrete leveling device, comprising two sets of side supports, each set of side supports having a base fixedly connected to its lower end, two sets of movable wheels fixedly installed on the left and right sides of the base, a traction ring fixedly connected to the front surface of the side supports, and the upper ends of the two sets of side supports being connected by a crossbar; a connecting sleeve is fitted on the crossbar, and the lower end of the connecting sleeve is connected to an insert rod via a connecting rod, and a trowel plate is connected to the lower surface of the insert rod.

[0007] Preferably, the lower end of the side bracket is configured as a T-shaped structure, and the upper end of the side bracket is configured as an L-shaped structure, with the T-shaped structure being more stable.

[0008] Preferably, the left and right ends of the crossbar are movably inserted into the upper ends of the two sets of side brackets, and the outer surface of the two sets of side brackets that are close to each other is threaded with locking bolts that cooperate with the crossbar, so as to facilitate the adjustment of the distance between the two sets of side brackets and the quick positioning and fixing.

[0009] Preferably, the connecting sleeve is movably fitted onto the crossbar, and the upper surface of the connecting sleeve is threaded with a locking bolt that cooperates with the crossbar, so that the position of the connecting sleeve on the crossbar can be adjusted by sliding.

[0010] Preferably, the insertion rod is configured as a T-shaped structure, with the upper end of the insertion rod movably inserted into the connecting rod, and the lower end of the connecting rod having a locking bolt threaded into its outer surface to cooperate with the insertion rod, allowing the extension length of the insertion rod to be freely adjusted according to actual operational needs.

[0011] Preferably, two sets of plug-in blocks are provided in the middle of the upper surface of the squeegee, and plug-in holes are provided on the plug-in blocks. The lower surface of the plug rod is provided with a slot that matches the plug-in blocks, and the front surface of the plug rod is provided with a threaded hole that matches the plug-in holes. The plug rod and the squeegee are fixed together by bolts, which makes the connection relatively stable and the disassembly and assembly operations convenient.

[0012] Preferably, a vibration motor is fixedly installed on both the left and right ends of the upper surface of the insertion rod, and the vibration motor is equipped with a wire. The other end of the wire is movably wound around the take-up post, and the take-up post is fixedly installed on the side bracket. By winding and storing the wire, the length of the wire can be flexibly adapted, which does not affect the operation and keeps it neat.

[0013] This utility model provides an engineering concrete leveling device, which has the following beneficial effects:

[0014] By using the side supports and crossbars in conjunction, the device can flexibly adjust its width according to the road surface width, making it highly adaptable to different road surface widths. This adjustable width design allows the device to easily adapt to various road surface scenarios.

[0015] By using the crossbar, connecting sleeve, connecting rod and insert rod in combination, the leveling work can be carried out with the connection between the squeegee and the device being flexible. Small-range lateral adjustments are required without moving the entire device, so the overall size and weight of the device can be reasonably controlled. Only a small amount of manpower is needed to complete the operation during the movement and adjustment process, which can also reduce damage to the leveled area and improve the convenience of operation.

[0016] By using the insertion rod and the trowel plate together, the trowel plate and the device are detachably connected, making cleaning easier and more thorough. The concrete residue left on the surface of the trowel plate during the leveling process is easier to remove, reducing long-term accumulation and maintaining the flatness of the trowel plate as much as possible, so as not to affect the subsequent leveling accuracy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 and Figure 2As shown, this embodiment proposes an engineering concrete leveling device, including side supports 1, which are provided in two sets. Each set of side supports 1 has a base 2 fixedly connected to its lower end. Two sets of movable wheels 3 are fixedly installed on the left and right sides of the base 2. A traction ring 4 is fixedly connected to the front surface of the side supports 1. The upper ends of the two sets of side supports 1 are connected by a crossbar 5. A connecting sleeve 6 is fitted onto the crossbar 5, and the lower end of the connecting sleeve 6 is connected to an insert rod 8 via a connecting rod 7. A troweling plate 9 is connected to the lower surface of the insert rod 8. The lower end of the side supports 1 is configured as a T-shaped structure, and the upper end of the side supports 1 is configured as an L-shaped structure. The left and right ends of the crossbar 5 are movably inserted into the two sets of... The upper end of the side bracket 1, and the outer surface of the two sets of side brackets 1 that are close to each other, are threaded with locking bolts that cooperate with the crossbar 5; the connecting sleeve 6 is movably sleeved on the crossbar 5, and the upper surface of the connecting sleeve 6 is threaded with locking bolts that cooperate with the crossbar 5; the insert rod 8 is set as a T-shaped structure, the upper end of the insert rod 8 is movably inserted into the connecting rod 7, and the lower end of the connecting rod 7 is threaded with locking bolts that cooperate with the insert rod 8; the upper surface of the insert rod 8 is fixedly installed with vibration motors 10 at both the left and right ends, and the vibration motors 10 are equipped with wires 11, the other end of the wires 11 is movably wound around the take-up post 12, and the take-up post 12 is fixedly installed on the side bracket 1.

[0026] In the above embodiment, during use, the entire unit is placed in a suitable position, and the width between the two sets of side brackets 1 is adjusted according to the width of the road. During adjustment, first loosen the bolts at the upper end of the two sets of side brackets 1, then move the two sets of side brackets 1 laterally to a suitable position, and then tighten the bolts for limiting and fixing. Since the connecting sleeve 6, the insert rod 8 and the squeegee 9 are interconnected, when it is necessary to adjust the position of the squeegee 9, simply slide the connecting sleeve 6 laterally on the crossbar 5, and then fix it by limiting with bolts. Finally, adjust the insert rod 8 downwards until the squeegee 9 contacts the ground to a suitable position, and then fix it by limiting with bolts. At this point, the preparation work is completed.

[0027] Example 2

[0028] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes that: two sets of plug-in blocks are provided in the middle of the upper surface of the trowel plate 9, and plug-in holes are provided on the plug-in blocks; the lower surface of the plug rod 8 is provided with a slot that matches the plug-in blocks; the front surface of the plug rod 8 is provided with a threaded hole that matches the plug-in holes; and the plug rod 8 and the trowel plate 9 are fixed together by bolts.

[0029] In the above embodiment, after the preparation work is completed, the concrete surface leveling begins. First, the traction rope is hung on the traction rings 4 on the left and right sides respectively, and then the other end of the traction rope is hung on the rear end of the tractor. The tractor moves in a straight line along the route to be leveled, and the vibration motor 10 is started. The tractor will drive the entire device to move in a straight line. The trowel 9 will level the ground it contacts through the vibration of the vibration motor 10. The vibration of the trowel 9 is transmitted to the concrete surface, causing the particles inside the concrete to move relative to each other, filling the gaps, expelling air, reducing the porosity of the concrete, and increasing its density. At the same time, under the action of vibration, the concrete will flow to the low-lying areas, thereby achieving surface leveling. After the work is completed, the vibration motor 10 is turned off, and the trowel 9 is removed from the insertion rod 8 for cleaning and maintenance in preparation for the next use.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
