Abstract
The utility model discloses a spreading machine track hydraulic pressure automatic tension device and belongs to the technical field of spreading machines. The tension device comprises a track, a guiding wheel, a tension oil cylinder and a tension valve assembly of the tension oil cylinder, wherein the guiding wheel, the tension oil cylinder and the tension valve assembly are arranged on inner side of one end of the track. The guiding wheel is arranged inside a guide rail through a guiding wheel support. The front end of the guiding wheel abuts against the track. A piston in the tension oil cylinder abuts against the guiding wheel support through a spacer bush. The tension oil cylinder is fixed on a track beam. The tension valve assembly is communicated with the tension oil cylinder through a rubber tube. The spreading machine track hydraulic pressure automatic tension device is convenient to operate, and capable of prolonging service life of the tension oil cylinder and improving reliable performance of the spreading machines.
Description
Technical field
The utility model relates to a kind of paver, specifically a kind of paver crawler belt hydraulic pressure automatic tension mechanism.
Background technology
When the crawler belt of paver only was tensioned the oil cylinder tensioner, paver could be walked.Be used at present the track tension device of paver, generally adopt tensioned, its structure is complicated, not only assemble loaded down with trivial details, and to having relatively high expectations of manufacturing process and assembly technology, make the reliability of whole mechanism work be difficult for guaranteeing, also affected work efficiency simultaneously.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of paver crawler belt hydraulic pressure automatic tension mechanism, but auto-tensioning, and assembling is simple, improves the reliability of whole mechanism.
To achieve these goals, the technical solution adopted in the utility model is: a kind of paver crawler belt hydraulic pressure automatic tension mechanism, comprise crawler belt, be installed in track adjusting wheel, tensioning hydro-cylinder and the tensioning valve group thereof of crawler belt one end inboard, track adjusting wheel is installed in the guide rail by guide wheel bracket, the front end of track adjusting wheel withstands on the crawler belt, piston in the described tensioning hydro-cylinder withstands on the guide wheel bracket by spacer, tensioning hydro-cylinder is fixed on the track beam, tensioning valve group communicates with tensioning hydro-cylinder by sebific duct, and tensioning valve group is connected with gear type pump.
Further, the spacer device is on positioning guiding plate, and spacer is provided with give up the throne bolt and bolt one.
Further, tensioning hydro-cylinder is fixed on the track beam by bolt two, packing ring.
The beneficial effects of the utility model are: being equipped with of tensioning valve group is beneficial to paver and realizes better at work the constant speed performance; The simultaneously installation of spacer has been played the accurately effect of location of tensioning hydro-cylinder, guarantees that tensioning hydro-cylinder mainly bears axial force, and is not subjected to or only is subjected to very little side force and diametral load; Unload spacer by the bolt of giving up the throne, tensioning hydro-cylinder can be taken off easily, very convenient; The reliability of the whole mechanism of Effective Raise.

Fig. 2 is the utility model hydraulic schematic diagram.
Among the figure: 1, crawler belt, 2, track adjusting wheel, 3, guide rail, 4, guide wheel bracket, 5, piston, 6, guide positioning plate, 7, spacer, 8, bolt one, 9, the bolt of giving up the throne, 10 tensioning hydro-cylinders, 11, track beam, 12, bolt two, 13, packing ring, 14, oil pipe, 15, tensioning valve group, 16, gear type pump.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of paver crawler belt hydraulic pressure automatic tension mechanism, comprise crawler belt 1, be installed in track adjusting wheel 2, tensioning hydro-cylinder 10 and the tensioning valve group 15 thereof of crawler belt one end inboard, track adjusting wheel 2 is installed in the guide rail 3 by guide wheel bracket 4, the front end of track adjusting wheel 2 withstands on the crawler belt 1, piston 5 in the described tensioning hydro-cylinder 10 withstands on the guide wheel bracket 4 by spacer 7, tensioning hydro-cylinder 10 is fixed on the track beam 11, tensioning valve group 15 communicates with tensioning hydro-cylinder 10 by sebific duct 14, and tensioning valve group 15 is connected with gear type pump 16.
Described spacer 7 devices are on positioning guiding plate 6, spacer 7 is provided with give up the throne bolt 9 and bolt 1, positioning guiding plate 6 can make the location of tensioning hydro-cylinder 10 front ends more accurate, spacer 7 makes 10 of tensioning hydro-cylinders bear axial force, and be not subjected to or only be subjected to very little side force or diametral load, and be provided with the bolt 9 of giving up the throne at spacer 7, like this so that the dismantlement work of spacer 7 is convenient, tensioning hydro-cylinder 10 is fixed on the track beam 11 by bolt 2 12, packing ring 13.
Working process of the present utility model: the part fluid when crawler belt 1 is tighter in the tensioning hydro-cylinder 10 flows to fuel tank by tensioning valve group 15, when crawler belt 1 is loose, gear type pump 16 is oil-filled by 15 pairs of tensioning hydro-cylinders 10 of tensioning valve group with hydraulic oil, piston 5 in the tensioning hydro-cylinder 10 is pushed on the guide wheel bracket 4, thereby track adjusting wheel 2 moves forward along guide rail 3 with guide wheel bracket 4, with crawler belt 1 tensioning.
