A curb is a monument provided between a road surface and another structure. Curb stones are generally required to be arranged between a separation zone and a road surface of an urban road and between a sidewalk and the road surface, and the curb stones are usually required to be arranged at the edge of a central separation zone of a road, the edge of the right side of a traffic lane or the edge of the outer side of a road shoulder. The kerbstone usually has two forms, one is ordinary concrete prefabrication, one is stone material processing, and the kerbstone of concrete prefabrication needs to adopt slipform paver to pave and forms. The slipform paver is likely to cause the problem of the slipform paver deviating the route due to the driving side of the paver being out of center in the paving process, and the patent with the publication number of CN 209555725U: a traction balance structure of a mold of a slip film paver comprises a vehicle body, wherein the vehicle body comprises a plurality of supporting legs and a mold forward supporting leg, and the mold forward supporting leg is positioned right ahead of the mold in the length direction and is detachably and fixedly connected through a connecting frame; the bottom ends of the forward supporting legs of the mold are provided with power crawler assemblies which can independently lift power; the forward supporting legs of the die are hinged with the car body through connecting rods. The balance structure can effectively avoid vehicle deviation and improve the deviation adjusting capability. The crawler traveling mechanism is directly arranged on the other side of the front supporting leg, if the gravity center of the paver deviates or the paving working condition changes, the gravity center needs to be adjusted or the crawler traveling mechanism needs to be adjusted, the adjustment cannot be realized, in addition, the arrangement of the adjustable height of the front supporting leg does not accord with the working condition of the paver, the total weight of the paver is generally over 10 tons, for example, the weight of the paver of the LTU90.00 model of the applicant reaches 25 tons, and the adjustment of the height of the front supporting leg under the condition of large weight can be realized by equipment with large power consumption.

As shown in fig. 1 to 5 (for convenience of illustration, fig. 4 does not show a chain wheel and chain mechanism; fig. 5 does not show a balance frame), the utility model relates to a balance structure of a crawler-type slipform paver, which comprises a balance frame 6 arranged on a body 1 of the slipform paver in a sliding manner, a crawler traveling mechanism is arranged on the balance frame 6, one side of the crawler traveling mechanism is provided with a universal wheel component, the universal wheel component and the crawler traveling mechanism are arranged in sequence along the traveling direction of the crawler-type slipform paver, and a universal wheel 2 of the universal wheel component and a crawler 3 of the crawler traveling mechanism are all at the same height as a crawler 3 of the crawler-type slipform paver; the slipform paver body 1 is provided with a chain wheel and chain mechanism, a balance rack 6 is fixedly connected on a chain 4 of the chain wheel and chain mechanism, a wheel shaft of a driving chain wheel of the chain wheel and chain mechanism is fixedly connected on a speed reducing motor 5, and the speed reducing motor 5 is fixedly connected on the slipform paver body 1. A sliding frame 7 is fixedly arranged on a front baffle plate of a sliding-mode paver body 1, and a balance rack 6 is arranged on the sliding frame 7 in a sliding mode. The crawler travelling mechanism comprises a second speed reducing motor 8 fixedly connected to the balance rack 6, and an output shaft of the second speed reducing motor 8 is fixedly connected with a driving wheel 9; the crawler belt walking mechanism further comprises a driven wheel 10 which is rotatably connected to the balance rack 6, and the crawler belt 3 is wound on the driving wheel 9 and the driven wheel 10. The universal wheel assembly comprises a universal wheel seat 11 fixedly connected to the balance rack 6, a joint bearing is arranged on the universal wheel seat 11, and a universal wheel 2 is rotatably arranged on the joint bearing; the horizontal tangent plane of the lowest part of the universal wheel 2 is positioned on the same horizontal plane with the crawler 3 of the crawler traveling mechanism and the crawler 3 of the crawler sliding formwork paver. The balance rack 6 is of a cuboid frame structure, an inclined rod 12 which is obliquely arranged is fixedly arranged below the balance rack 6, one end, far away from the balance rack 6, of the inclined rod 12 is rotatably connected with a roller, a sliding rail 13 which is fixedly connected to a front baffle plate of the slipform paver body 1 is arranged below the sliding frame 7, and the inclined rod 12 is slidably arranged on the sliding rail 13.

The working principle is as follows:

the second speed reducing motor also acts to drive the crawler traveling mechanism in the balance structure to travel when the crawler sliding formwork paver advances, so that the problem of paver route deviation caused by unilateral driving is avoided, if the deviation still occurs, the position of the balance rack is correspondingly adjusted according to the deviation condition, forward rotation or reverse rotation of the chain is realized through forward and reverse rotation of the speed reducing motor, and therefore the left movement or the right movement of the balance rack is driven, and the position of the balance rack is adjusted. Or the center of gravity of the paver is firstly measured according to the paving working condition before paving (the measurement of the center of gravity is the prior art, and a method for measuring the center of gravity position of a passenger vehicle by an automobile axle load detector can be referred to, for example, the measurement of the center of gravity position of a two-axle road vehicle), if the center of gravity is not at the center position of the paver, a balance rack is adjusted to a proper position, then a second speed reducing motor also acts to drive a crawler travelling mechanism in the balance structure to travel when the crawler-type sliding formwork paver travels, so that the problem of route deviation of the paver caused by unilateral driving is avoided.

The crawler-type slip form paver vibrates and compacts the cement concrete while advancing; meanwhile, the slipform paver self-carries out leveling on the compacted road section synchronously by touching the rear template plate, so that the road surface flatness is ensured.
