Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a ground leveling device for building workshops. Background Technology
[0002] Ground leveling equipment is widely used in factory construction to level and compact concrete or other paving materials. Existing roller-type ground levelers consist of a frame, rollers, and a power system. During use, the rollers are pressed onto the concrete to be leveled, and the power system drives the rollers to roll. Workers pull the equipment forward from both ends of the frame, allowing it to move slowly forward and continuously roll over the concrete surface to level it.
[0003] However, existing roller-type floor leveling machines have the following drawbacks: during use, workers need to pre-distribute the material to be leveled evenly to avoid some areas being too thick or too thin, which increases the labor intensity of workers and results in poor leveling functionality.
[0004] In view of this, we propose a ground leveling device for building workshops. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a building factory floor leveling device that can distribute materials evenly before leveling and compaction, simplify the construction process, save manpower, and thus overcome the shortcomings of the existing technology.
[0006] To solve the above-mentioned technical problems, this utility model provides a building factory floor leveling device, including a frame, a roller and a movable rake;
[0007] The roller is rotatably mounted below the frame, and two sets of movable rakes are symmetrically mounted on the frame and extend to the front end in the direction of travel.
[0008] The movable rake includes a horizontally arranged long rocker arm, a short rocker arm, a first connecting rod, and vertically arranged rake teeth. The long rocker arm and the short rocker arm are hinged to the top of the frame near their roots, and their outer ends are hinged to both ends of the first connecting rod, so that the long rocker arm, the short rocker arm, and the first connecting rod form a parallelogram linkage mechanism. Several rake teeth are spaced apart on the bottom surface of the long rocker arm and the short rocker arm.
[0009] Two sets of movable rakes are driven by a second motor to swing synchronously in a fan shape. The rake teeth are used to distribute the material at the front of the moving direction evenly, and the rollers are driven by a first motor to roll and compact and level the material.
[0010] As an improvement of this utility model, a swing mechanism is provided between the movable rake and the output end of the second motor;
[0011] The swing mechanism includes a second link and a third link. One end of the second link is fixedly connected to the output shaft of the second motor, and the other end is hinged to the third link. The other end of the third link is hinged to the root of the long swing rod, so that the second link and the third link constitute a crank-connecting rod mechanism.
[0012] Furthermore, the rake teeth are arranged at equal intervals.
[0013] With this design, the present invention has at least the following advantages.
[0014] 1. This utility model has two sets of movable rakes that move synchronously in a fan shape at the front end of the frame in the direction of travel. This can pre-distribute the material in front evenly, and then level and compact it through the rollers, which can improve the subsequent leveling effect, simplify the construction process, and save manpower.
[0015] 2. Simple structure, easy to use, and low cost. Attached Figure Description

[0022] Please see Figures 1 to 4 This utility model provides a floor leveling device for building workshops, including a frame 1, a roller 2, a first motor 3, a swing mechanism 4, a movable rake 5, and a second motor 6.
[0023] The frame 1 provides mounting points for the roller 2, the first motor 3, the swing mechanism 4, the movable rake 6, and the second motor 6. Handrails are provided at both ends of the frame 1, and construction workers can push or drag the frame 1 to carry out construction.
[0024] The roller 2 is rotatably mounted below the frame 1 and is driven by the first motor 3 to roll, leveling and compacting the ground paving material as the frame 1 moves. In this embodiment, the first motor 3 is mounted below the frame 1 and transmits power to the roller 2 via a belt.
[0025] Two sets of the movable rakes 5 are symmetrically installed on the top of the frame 1 and extend towards the front end in the direction of travel.
[0026] Each set of moving rakes 5 includes a horizontally arranged long rocker arm 502, a short rocker arm 501, a first connecting rod 503, and vertically arranged rake teeth 504.
[0027] Both the long rocker arm 502 and the short rocker arm 501 are hinged to the top of the frame 1 near their roots, and their outwardly extending ends are hinged to both ends of the first connecting rod 503, so that the long rocker arm, the short rocker arm and the first connecting rod form a parallelogram linkage mechanism.
[0028] It should be noted that although the long rocker arm 502 is longer than the short rocker arm 501, the lengths of both extending from the front end of the frame 1 are equal. This makes their motion trajectories parallel to each other, forming the motion trajectory of a parallelogram linkage mechanism. The reason why the long rocker arm 502 is longer and is installed closer to the middle of the frame 1 is to facilitate connection with the swing mechanism 4.
[0029] The rake teeth 504 are vertically arranged at intervals on the bottom surfaces of the long rocker arm 502 and the short rocker arm 501. In this embodiment, the rake teeth 504 are evenly spaced. The function of the rake teeth 504 is to pre-distribute the material to be leveled and compacted evenly. The rake teeth 504 perform a comb-like motion during movement.
[0030] The second motor 6 is installed at the bottom center of the frame 1 and is connected to two sets of movable rakes 5 through the swing mechanism 4, which is used to drive the two sets of movable rakes 5 to swing synchronously in a fan shape.
[0031] The swing mechanism 4 includes a second connecting rod 401 and a third connecting rod 402. One end of the second connecting rod 401 is fixedly connected to the output shaft of the second motor 6, and the other end is hinged to the third connecting rod 402. The other end of the third connecting rod 402 is hinged to the root of the long swing rod 502, thus forming a crank-connecting rod mechanism. The function of the swing mechanism 4 is to convert the continuous output torque of the second motor 6 into a pushing and pulling force on the root of the long swing rod 502, thereby causing the two sets of movable rakes 5 to swing synchronously in a fan shape.
[0032] This utility model has a simple structure and is easy to use. It can pre-distribute materials evenly and then level and compact them with rollers, simplifying the construction process and saving manpower.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the disclosed technical content shall fall within the protection scope of the present utility model.
