Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of asphalt concrete paving construction, especially relates to a basic asphalt concrete surface paving device. BACKGROUND

[0002] In the road construction process, the roadbed often adopts the material composed of asphalt and concrete to carry out paving. Specifically, the construction equipment pours the asphalt and concrete material on the road during the construction process, and then uses a forklift or the like to preliminarily pave the material on the roadbed. However, the forklift or the like can only carry out preliminary rough paving, and the flatness after paving is not high.

[0003] The operator needs to carry out secondary paving during the construction process. The current paving operation is mainly carried out by large paving machinery. However, the limitation of large paving machinery lies in that it can only be used in the case of wide and long roads (main traffic arteries), and its flexibility and mobility are poor.

[0004] As for narrow roads, large operating equipment cannot enter the operation at all, and the current method can only be manual paving. Specifically, after the material is preliminarily paved by the forklift or the like, the operator uses a shovel plate or the like to manually pave and flatten. However, although this method has high flexibility, the operation efficiency and workload are large.

[0005] Especially for narrow and long roads, the above-mentioned operation method has a very large labor amount, and the operation difficulty is greater in high-temperature weather. In high-temperature weather, asphalt and other materials are prone to softening and sticking, and emit irritating odors, resulting in a very large workload for paving operation. INVENTION CONTENTS

[0042] Example 1

[0043] like Figures 1-5 As shown, a basic asphalt concrete pavement paving device includes a drive roller mechanism. The specific structure of the drive roller mechanism is as follows: the drive roller mechanism includes a wheel frame 11, and motor mounting sleeves 12 are integrally formed at the front and rear ends of the wheel frame 11. A roller motor 14 is installed inside the motor mounting sleeve 12. According to the existing roller drive method, a drive roller 13 is fixedly connected to the output shaft of the roller motor 14.

[0044] A paving mechanism is fixedly connected to both sides of the drive roller mechanism (the left and right sides of the wheel frame 11). The paving mechanism includes a frame, which has the following shape: the frame includes inclined end frames 22 spaced apart at the front and rear. The inclined end frames 22 are detachably mounted with connecting frames 23 fixedly connected to the motor mounting sleeve 12 (specifically, fixed by bolt fastening). Several column rods 221 are fixedly connected to the bottom of the inclined end frames 22, and frame-shaped frames 21 are fixedly connected between the column rods 221. The motor is fixedly mounted on the frame-shaped frames 21. Specifically, several T-shaped frames are fixedly connected to the frame-shaped frames 21, and the motor 41 is mounted on the T-shaped frames.

[0045] Meanwhile, several paving units are installed at the bottom of the frame; during operation, as the entire device moves along the road, multiple paving units work together to efficiently spread the material onto the roadbed.

[0046] The paving unit includes a paving plate 44 (in the conventional manner, a frame-shaped reinforcing rib 441 is welded to the top of the paving plate 44 to increase the stability of the paving plate 44), which is mounted on the frame by a swing structure.

[0047] Specifically, the swing structure includes a motor 41 fixedly mounted on a frame, and the output shaft of the motor 41 is equipped with a rotating wheel 42.

[0048] The eccentric portion of the rotating wheel 42 is hinged to a crank 43 (specifically, the crank 43 is hinged to the eccentric portion of the rotating wheel 42 via a pin), and the crank 43 is hinged to a mounting rod 431, which is fixedly installed at the center of the top of the paving plate 44.

[0049] During operation, when the paving board 44 is supported on the paved road material, it is driven by the motor 41, which uses the rotating wheel 42 and the eccentrically hinged crank 43 to swing the paving board 44. During the swinging process, the paving board 44 continuously swings and smooths the paved road material, thus spreading and flattening the material. With the cooperation of multiple paving boards 44, rapid and efficient paving is achieved.

[0050] Example 2

[0051] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the top two sides of the above-mentioned flat plate 44 are respectively hinged to the frame through a hinge structure.

[0052] Specifically, the hinged structure 45 comprises lower hinge pieces fixedly connected to the top of the flattening plate 44 at the front and rear sides, and upper hinge pieces fixedly connected to the bottom of the frame 21 at the front and rear sides and matched with the lower hinge pieces; the lower hinge pieces and the upper hinge pieces are fixedly connected through a hinge rod 452. The upper hinge pieces and the lower hinge pieces each comprise a hinge seat 451, the hinge seat 451 is hingedly connected with a hinge ball 452, and the hinge rod is fixedly connected between the hinge balls 452.

[0053] During the swinging of the flattening plate through the eccentric mode, the upper hinge pieces and the lower hinge pieces are matched to swing, thereby keeping the swinging flattening movement of the entire flattening plate 44 highly stable.

[0054] Embodiment 3

[0055] As shown in Figures 1-5 the structure of Embodiment 2, the asphalt concrete surface flattening device further comprises a steel wire suspension structure. Specifically, since the left and right racks have a large span, the rack is pulled through the steel wire suspension structure to increase the stability of the entire device.

[0056] Specifically, the steel wire suspension structure is suspended between the inclined end racks 22.

[0057] The steel wire suspension structure comprises two steel wire lifting ropes 31 arranged in an inclined cross shape, i.e., the two steel wire lifting ropes 31 are in an X shape. The opposite ends of the steel wire lifting ropes 31 are fixedly connected to the end positions of the inclined end racks 22, and correspondingly, the end positions of the inclined end racks 22 are fixedly connected with lifting arms 3 for fixedly connecting the steel wire lifting ropes 31.

[0058] The center of the wheel rack 11 is fixedly connected with a support rod part for supporting the steel wire lifting ropes 31; the support rod part comprises a support rod 32 fixedly connected to the wheel rack 11, and a pair of locking seats 32 for extruding and positioning the steel wire lifting ropes 31 are threadedly connected to the upper end of the support rod 32 (a threaded hole is formed in the middle of the locking seat, and the locking seat is threadedly connected to the support rod in a threaded connection mode), and the intersection of the steel wire lifting ropes 31 is locked and pressed between the locking seats 32. Specifically, the intersection of the steel wire lifting ropes 31 is supported on the lower locking seat 321, and then the upper locking seat 321 is extruded onto the steel wire lifting ropes 31.

[0059] This mode has the advantage that the steel wire lifting ropes 31 can be tensioned, i.e., the locking seat 31 is adjusted upward when the steel wire lifting ropes 31 are loose.

[0060] In actual work, in order to increase the stability of the locked steel wire, a clamping groove is formed on the locking seat to facilitate clamping the steel wire.

[0061] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
