Description

Technical Field

[0001] The utility model relates to the technical field of road construction devices, in particular to an anti-slip groove pulling device for an asphalt pavement. Background Art

[0002] With the development of municipal road projects in my country, the construction of concrete surface of village roads is becoming more and more frequent. When carrying out such construction, the subsequent anti-slip structure construction is crucial to the safety of vehicle driving.

[0003] At present, when the existing device is used, the worker only needs to hold the handle and drag it forward, and the groove teeth at the rear will leave marks on the unsolidified concrete road surface. When the road surface is grooved, there will be blank space, that is, one section is set with anti-slip grooves, and the other section is not set with grooves. Therefore, in order to facilitate leaving blank spaces during construction, a telescopic ruler is also set on the crossbar of the device. The telescopic ruler extends out of the crossbar and can quickly mark the position and width of the blank space.

[0004] For example, a concrete pavement anti-slip groove device disclosed in the authorization announcement number CN218596853U includes a rod-shaped handle, the end of the handle is connected to a cross bar perpendicular to the handle, and groove teeth are fixed on the cross bar. The groove teeth are provided with multiple groove teeth and the multiple groove teeth are arranged at intervals along the cross bar. The groove teeth are in the shape of an arc with the middle part protruding downward. The top of the groove teeth is fixed on the cross bar, and the bottom of the groove teeth is pressed on the road surface. A telescopic ruler is provided on the cross bar, and the telescopic ruler is slidably mounted on the cross bar and can slide along the axis direction of the cross bar. The telescopic ruler can extend outward from the left and right ends of the cross bar, and the telescopic ruler has scale marks. Preferably, the groove teeth are made of steel bars, which are bent into an arc shape. Preferably, the groove teeth include an arc segment and a straight line segment, the top of the arc segment is fixed on the cross bar, and the bottom of the arc segment continues to extend backward to form a straight line segment, and the straight line segment is parallel to the ground. Preferably, a set screw is provided on the crossbar, and the end of the set screw is pressed against the telescopic ruler to fix the telescopic ruler. Preferably, a straight reference ruler is fixed to one end of the telescopic ruler, and the straight reference ruler is a flat plate perpendicular to the telescopic ruler. Preferably, a fixing block is provided on the crossbar. However, such an anti-slip groove drawing device for concrete pavement is not convenient for adjusting the groove drawing range of the groove drawing wire, and it is not convenient to adjust the groove drawing depth of the groove drawing wire.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is inconvenient to adjust the groove range of the straight section and it is inconvenient to adjust the groove depth of the straight section. Therefore, it is necessary to improve the existing technology. Utility Model Content
