Description
The technical field is as follows:
the utility model relates to an asphalt concrete paver equipment technical field, in particular to screw axis.
Background art:
the asphalt concrete paver is a machine for uniformly paving an asphalt mixture on a road base layer and performing preliminary compaction and leveling; during operation, the front push roller of the paver pushes the rear wheel of the material-carrying dump truck to advance, receives the asphalt mixture, evenly paves the asphalt mixture to the left side and the right side by the left and the right spiral shafts of the spiral distributor, and performs preliminary compaction and leveling on a paving layer according to certain width, thickness and camber along with the forward movement of the paver.
The screw shaft used at present consists of a transmission shaft and screw blades fixed on the transmission shaft, wherein the transmission shaft is provided with a plurality of through holes, and each screw blade passes through the through hole through a bolt and is fixed on the transmission shaft; because the spiral shafts are provided with the plurality of through holes, the strength of the spiral shafts is reduced, in order to avoid the fracture of the spiral shafts and prolong the service life, each spiral shaft is generally divided into at least two sections, the end parts of the two adjacent sections of spiral shafts are butted through the hanging bracket of which the bottom end is fixed with the bearing, and the spiral shafts are supported through the hanging bracket; in the actual operation process, due to the existence of the hanging frames, the spiral conveying at the hanging frames is not smooth, the continuity and the uniformity of conveying of the mixture along the spiral in the width direction are damaged, the compactness and the gradation at the positions are influenced, and a longitudinal segregation belt is generated at each hanging frame on the paved road surface; the common method for treating pavement segregation is to fill fine materials into a paved segregation belt, fill gaps, then roll the segregation belt, or uniformly spray modified emulsified asphalt binder oil on the segregation part after the temperature of the rolled pavement is reduced to room temperature, then spread a proper amount of asphalt premixed stone chips, and then roll the pavement again, thereby increasing the consumption of raw materials and energy, simultaneously prolonging the construction period, reducing the laying efficiency, and reducing the laying quality of the whole pavement by laying again.
The utility model has the following contents:
an object of the utility model is to provide a reduce raw materials and energy resource consumption, improve road-surfacing efficiency in order to shorten construction cycle, and guarantee the screw axis of road-surfacing quality.
The utility model discloses by following technical scheme implement: a spiral shaft comprises a transmission shaft and a plurality of sleeves which are uniformly sleeved on the transmission shaft along the axial direction; the sleeve is formed by buckling two semicircular sleeve assemblies, and the two semicircular sleeve assemblies are fixedly connected through bolts; the outer wall of each semicircular sleeve assembly is fixed with a spiral blade assembly, the end parts of two adjacent spiral blade assemblies are arranged oppositely, and each spiral blade assembly forms an integral spiral blade assembly coiled on the transmission shaft.
Furthermore, the outer walls of two sides of the opening end of the semicircular sleeve assembly are respectively and vertically fixed with a fixing lug, and the semicircular sleeve assemblies which are mutually buckled pass through the bolt to fixedly connect the fixing lugs.
Further, the transmission shaft is a hollow bending-resistant steel pipe.
The utility model has the advantages that: the semi-circular sleeve pipe assembly fixed with the spiral blade assembly is buckled on the outer wall of the transmission shaft, the semi-circular sleeve pipe assemblies buckled with each other are fixedly connected through bolts, holes are prevented from being punched on the transmission shaft to fix the spiral blade assembly, the strength of the transmission shaft is effectively ensured, the service life of the transmission shaft is prolonged, the spiral shaft does not need to be arranged in a segmented mode, a hanging bracket used for connecting and supporting each section of spiral shaft on the spiral distributing device can be eliminated, the continuity and the uniformity of conveying of the mixture along the spiral shaft in the width direction are ensured, and the occurrence of a longitudinal segregation band after paving is avoided; from this, can guarantee the holistic quality of laying of road surface through once only accomplishing to lay, improve simultaneously and lay efficiency, shorten construction cycle, reduced the consumption of raw materials and energy moreover.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a rear view of fig. 1.
Fig. 3 is a sectional view a-a of fig. 1.
The parts in the drawings are numbered as follows: the device comprises a transmission shaft 1, a sleeve 2, a semicircular sleeve assembly 3, a bolt 4, a helical blade assembly 5 and a fixing lug 6.
The specific implementation mode is as follows:
as shown in fig. 1 to 3, a screw shaft includes a transmission shaft 1, the transmission shaft 1 is a hollow anti-bending steel pipe; a plurality of sleeves 2 are uniformly sleeved on the transmission shaft 1 along the axial direction; the sleeve 2 is formed by buckling two semicircular sleeve assemblies 3, and the two semicircular sleeve assemblies 3 are fixedly connected through bolts 4; the outer wall of each semicircular sleeve assembly 3 is fixed with a spiral blade assembly 5, the end parts of two adjacent spiral blade assemblies 5 are oppositely arranged, and each spiral blade assembly 5 forms an integral spiral blade assembly wound on the transmission shaft 1; fixing lugs 6 are respectively and vertically fixed on the outer walls of two sides of the opening end of the semicircular sleeve assembly 3, and the two semicircular sleeve assemblies 3 which are mutually buckled penetrate through the fixing lugs 6 through bolts 4 to be fixedly connected; the semi-circular sleeve assemblies 3 which are buckled with each other are fixedly connected by penetrating through the fixing lugs 6 through the bolts 4 and are tightly clamped on the outer wall of the transmission shaft 1, so that the spiral vane assemblies 5 are prevented from being fixed by punching holes on the transmission shaft 1, the strength of the transmission shaft 1 is effectively ensured, and the service life of the transmission shaft 1 is prolonged; this screw axis is overall structure, need not carry out the segmentation setting in the in-service use process, and then can be used for connecting and supporting the screw axis gallows cancellation of segmentation on the spiral distributing device to this guarantees continuity and the homogeneity that the mixture carried along the screw axis in the width direction, avoids the appearance of the vertical segregation area after paving, improves the road surface and lays the quality.
Instructions for use: the semicircular sleeve pipe assemblies 3 which are mutually buckled penetrate through the bolts 4 to be fixedly connected with the fixing lugs 6 and are tightly clamped on the outer wall of the transmission shaft 1, each semicircular sleeve pipe assembly 3 fixed with the spiral blade assembly 5 is fixed along the transmission shaft 1 in sequence in a fixing mode, so that an integral spiral blade assembly coiled on the transmission shaft 1 is formed through each spiral blade assembly 5, a complete spiral shaft is formed, and the spiral shaft can be installed on the spiral distributor to be used.
