Description

Transfer vehicle for municipal road kerbstone installation Technical Field The invention relates to the technical field of municipal road pavement, in particular to a transfer vehicle for municipal road kerbstone installation. Background In the municipal road pavement construction process, the curbstone (also called as curb and curbstone) is difficult to carry because of large weight and large size, and the installation efficiency is greatly affected by carrying. At present, the conventional mode of centralized unloading and manual dispersion is mainly adopted for the installation of the curbstone, namely, piled curbstones are firstly placed at intervals along a road by using a transfer truck such as a forklift, and then a worker moves the single curbstone to an installation position for paving by carrying by bare hands or simply picking and lifting tools. The operation mode has high labor intensity and low efficiency, and is easy to cause waist injury of operators. In order to reduce the labor intensity of workers, the prior art proposes some auxiliary carrying tools. For example, patent document CN213681614U discloses a curbstone installation tool, which adopts a lever principle to hang curbstone on an operation rod through manual operation and then perform short distance transportation. However, the auxiliary tool has obvious limitations that firstly, only a single roadside stone or a few roadside stones can be transported at a time, and continuous multi-block transportation cannot be realized, secondly, pure manual operation is relied on, the transportation distance is limited, the applicability to long-distance scattered operation scenes along the road is poor, thirdly, the auxiliary tool lacks a connection function with an installation procedure, the roadside stones still need to be manually removed after being positioned, and the installation position is manually adjusted, so that the operation efficiency is difficult to improve. In addition, cement mortar is required to be coated on the base layer before the roadside stone is installed so as to ensure bonding strength and levelness, and the transportation of the mortar is also a key link for limiting construction efficiency. Because the road side stone pavement has the characteristics of 'linear continuity, point location dispersion and sporadic use amount', namely the road pavement is continuous along the longitudinal direction of the road, but the use amount of mortar at each installation point is less, and the mortar needs to be supplied at any time according to the progress, and the existing large-scale transportation equipment (such as a mortar mixer truck and a belt conveyor) cannot be suitable due to poor maneuverability and minimum transportation quantity limitation. At present, the construction site mainly relies on manual lifting of a mortar barrel or a hand-push ash bucket truck for transportation, so that the defects of low efficiency, high labor intensity of workers and the like exist, and the mortar is easy to cause water evaporation after long-time exposure, so that the adhesive property is affected, and the quality is difficult to guarantee especially in high-temperature or windy weather. To sum up, the prior art lacks the integrated construction equipment that can solve the efficient transportation of roadside stone and the synchronous delivery of mortar simultaneously, and the development of a special device that adapts to the linear construction characteristics of municipal road, realizes that the roadside stone is carried in succession and is supplied with cooperation with the mortar is accurate to reduce artifical reliance, promote quality of mating formation and efficiency of construction is urgently needed. Disclosure of Invention In order to overcome the defects of the conventional transfer and pavement of curbstone, the invention aims to provide a transfer vehicle for mounting the curbstone of municipal road, which can realize the cooperative operation of continuous transfer of the curbstone and accurate supply of mortar. The technical scheme adopted for solving the technical problems is as follows: The transfer trolley for mounting the curbstone on the municipal road comprises a carriage and travelling wheels, wherein a mortar storage bin is arranged on the outer side of the bottom of the carriage, a transverse transport wheel and a vertical transport wheel which are driven to rotate by a driving mechanism are arranged on the inner side of the bottom of the carriage, a curbstone discharge opening is arranged at the bottom corner position of one side plate arranged in the carriage along the length direction of the side plate, the transverse transport wheels are arranged in an area opposite to the curbstone discharge opening, a plurality of transverse transport wheels are arranged at intervals along the width direction of the carriage, the axis of a rotating shaft of each transverse transport wheel is parallel to the length d
