Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt concrete paving facilities, and in particular relates to a steel wire fixing and winding device for an asphalt concrete paving routing method. Background Art

[0002] At present, asphalt concrete paving construction on highways and urban roads mostly adopts two construction methods, one is the line method and the other is the balance beam method. When paving the lower layer of asphalt concrete, the line method is mostly used for construction. This method can ensure flatness and is conducive to controlling the overall elevation. The paving length can reach more than 500m at a time, and then the next section of the cycle construction can be carried out. When the line method is used for construction, 2-3mm steel wire is usually used. The conventional method is to use steel bars to fix one end of the steel wire and tighten it from the other end so that the main part of the steel wire is located above the road surface. During construction, this section of steel wire is used as the elevation reference line for paving construction.

[0003] This method of arranging steel wires has the following problems: first, the arrangement method is cumbersome and laborious, and the steel wires are usually long, which is not conducive to transfer and arrangement, and are prone to entanglement, breakage and other problems; second, the steel wire arrangement needs to be tensioned, and the existing arrangement device cannot keep the steel wire in a continuous tensioned state and is not easy to operate and re-tension after the steel wire sags, which leads to problems with the asphalt paving elevation and further leads to quality problems in asphalt concrete construction. Therefore, it is necessary to develop a steel wire fixing and winding device for the routing method to solve the above problems. Utility Model Content

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0025] See also Figure 1 and Figure 2 The utility model of the steel wire fixed winding device for asphalt concrete paving routing method comprises a bracket, a spool 9 is mounted on the bracket, a crank 8 is mounted on one end of the central axis of the spool 9, and a parking component 10 acting on the other end of the central axis of the spool 9 is also mounted on the bracket. The steel wire is wound on the spool 9. During operation, the spool 9 is driven by the crank 8 to rotate forward or reverse to realize unwinding and rewinding of the steel wire. After the unwinding and rewinding operation of the steel wire is completed, the parking component 10 is used to act on the other end of the spool 9, so that the spool 9 is parked and maintained at the current position and cannot be flexibly rotated.

[0026] As shown in the figure, the bracket includes a bottom plate 1 in the middle and bottom side frames 2 respectively located on both sides of the bottom plate 1, support frames 3 are fixedly mounted on the two bottom side frames 2, and reinforcing support rods 4 are fixedly mounted between the support frames 3 and the bottom side frames 2 on the same side, and shaft seats 12 are installed in the middle of the two support frames 3, and the central axis end of the bobbin 9 is located in the shaft seat 12. As shown in the figure, the two support frames 3 are both door-type frames.

[0027] In this embodiment, the bottom side frame 2 includes a side frame outer frame, an inner frame profile is fixedly installed inside the side frame outer frame, the bottom of the support frame 3 is fixedly connected to the inner frame profile, and an anchor hole is also provided on the inner frame profile, and the inner edge of the side frame outer frame is welded and fixed to the side edge of the bottom plate 1. The purpose of setting the anchor hole is: after the steel wire fixed winding device is moved to a suitable position at the construction site, the device is anchored to the ground with a ground anchor, which can improve the stability of the device and avoid the problem of changes in the steel wire elevation caused by displacement when the steel wire is pulled by external force and the device is squeezed by external force.

[0028] In this embodiment, two roller assemblies 5 are installed on the outer sides of the two bottom side frames 2. The roller assembly 5 is composed of a wheel seat and a roller installed on the outer end of the wheel seat. The inner end of the wheel seat is fixedly connected to the side frame outer frame of the bottom side frame 2, and the wheel seat extends toward the outer side and upward. The purpose of installing the roller assembly 5 on both sides of the bottom of the bracket is that when the steel wire fixed winding device is shifted at the construction site, the device can be tilted to one side until the two roller assemblies 5 on this side are in contact with the ground. At this time, the device can be dragged and shifted, which improves the operational convenience of shifting the device at the construction site.

[0029] In this embodiment, a lifting ring 11 is installed on the top of the two support frames 3. The lifting ring 11 is used to assist in carrying and moving the device.

[0030] A conductor block 7 and a hand-operated lifting assembly 6 for adjusting the height of the conductor block 7 are also provided at the front of the spool 9. The steel wire wound and unwound by the spool 9 passes through the wire hole on the conductor block 7. The conductor block 7 driven by the hand-operated lifting assembly 6 has two functions. One of the functions is to pull the free end of the steel wire to the other side of the construction road surface after releasing the steel wire at the construction site and fix it with a steel bar wedged into the ground. The fixed connection position with the steel bar is determined according to the elevation position of the steel wire. After that, the conductor block 7 should be operated by the hand-operated lifting assembly 6 on one side of the device to move up and down so that the steel wire is finally located at the set elevation position. Another function is that during the paving construction of asphalt concrete, some dust and impurities will adhere to the steel wire. When winding, the steel wire passes through the wire hole of the conductor block 7 to peel off the aforementioned dust and impurities.

[0031] See also Figure 3 , we can see that:

[0032] The hand-cranked lifting assembly 6 includes a lower end plate 6-1 and an upper end plate 6-9, a front vertical plate 6-2 is provided between the front parts of the two, and a side vertical plate 6-8 is provided between the side parts of the two. The upper ends of the front vertical plate 6-2 and the side vertical plate 6-8 are welded and fixed to the upper end plate 6-9, and the lower ends are welded and fixed to the lower end plate 6-1. The lower end plate 6-1 is fixedly connected to the bottom plate 1 by welding or bolting. In order to improve the overall structural strength, a reinforcing triangular plate 6-4 is also welded and installed between the side vertical plate 6-8 and the lower end plate 6-1.

[0033] A screw rod 6-5 is mounted on the upper end plate 6-9 through a bearing seat 6-10, a hand wheel 6-11 is mounted on the upper end of the screw rod 6-5, a lifting platform 6-7 is fixedly mounted on the screw nut on the screw rod 6-5, a lifting plate 6-6 is mounted on the lifting platform 6-7, and a conductor block 7 is fixedly mounted on the lifting plate 6-6. The screw rod 6-5 is operated by the hand wheel 6-11 to rotate forward or reverse, and the lifting plate 6-6 moves with the conductor block 7 to move up and down.

[0034] In this embodiment, two left and right guide strip holes 6-3 are provided on the front vertical plate 6-2, and a connecting plate is provided in the guide strip hole 6-3, the inner end of the connecting plate is fixedly connected to the lifting platform 6-7, and the outer end of the connecting plate 6-3 is fixedly connected to the lifting plate 6-6. By providing the guide strip hole 6-3 and the connecting plate, the stability of the lifting plate 6-6 and the conductor block 7 during lifting and moving is improved.

[0035] See also Figure 4 and Figure 5 , we can see that:

[0036] The parking assembly 10 includes a base plate 10-1, an upper support plate 10-2 is provided at the upper end of the base plate 10-1, and a lower support plate 10-3 is provided at the lower end. The base plate 10-1, the upper support plate 10-2 and the lower support plate 10-3 together constitute a base. The base is fixedly connected to the bracket, specifically, the base plate 10-1 can be fixedly connected to the support frame 3 by welding or by bolts.

[0037] A sleeve 10-4 is hingedly installed on the upper support plate 10-2, and a telescopic rod 10-5 is provided in the sleeve 10-4. A parking pressure block 10-10 with a groove is installed at the lower end of the telescopic rod 10-5. The parking pressure block 10-10 acts on the end of the central axis of the spool 9, and limits the spool 9 to the current position by applying friction to the axial end of the central axis so that it cannot rotate flexibly.

[0038] It also includes a parking operation mechanism for driving the telescopic rod 10-5 to telescopically move. When the telescopic rod 10-5 is extended downward, pressure friction is generated on the shaft end. When the telescopic rod 10-5 is retracted upward, it is separated from the shaft end.

[0039] In this embodiment, the parking operation mechanism includes a short arm 10-6 whose upper end is hingedly connected to the upper support plate 10-2 and a long arm 10-8 whose lower end is hingedly connected to the middle part of the telescopic rod 10-5.
