Abstract
The utility model discloses an arch-adjusting locking device of a spreading machine, comprising a left ironing board (1), a right ironing board (13), a hydraulic pressure hydro-cylinder (2) and a rotating shaft (12); a second supporting column (7) is arranged on the right ironing board (13), a second pin shaft (8) is articulated on the second supporting column (7), a first supporting column (14) is arranged on the left ironing board (1), one end of a screw stem (4) is articulated on the first supporting column (14) by a first pin shaft (3), and the other end thereof is inserted on the second pin shaft (8), the screw stem (4) is provided with a first adjusting nut (6) and a second adjusting nut (9) which are arranged at two sides of the second pin shaft (8) respectively, and a first nut (5) and a second nut (9) which are corresponding to the first adjusting nut (6) and the second adjusting nut (9) respectively; in order to realize the locking in the arch-adjusting process, the purpose of eliminating the effect on arch-adjusting caused by shifting owning to the leakage of the hydraulic pressure hydro-cylinder is achieved. The structure is novel and the operation is rapid and labor-saving.
Description
Technical field
The utility model relates to a kind of paver, particularly relates to a kind of paver and transfers crown tightly to install.
Background technology
Pressing its cross section of road construction standard needs certain camber, and the screed of paver is provided with transfers arch mechanism, and traditional accent arch mechanism is that manual ratchet drive screw mandrel is transferred arch, and operation is hard, efficient is low.If change that hydraulic jack drive to be transferred arch into then swift to operate laborsaving, eliminate oil cylinder and leak the influence of exchanging arch but locking device need be set.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly to be eliminated the paver that oil cylinder leaks the influence exchange arch and transfers crown tightly to install.
In order to solve the problems of the technologies described above, the paver that the utility model provides transfers crown tightly to install, comprise left screed, right screed, hydraulic jack and rotating shaft, described right screed is provided with second pillar, on described second pillar, be hinged with second bearing pin, described left screed is provided with first pillar, screw rod one end is hinged on described first pillar by first bearing pin, the other end interts on described second bearing pin, on described screw rod, be provided with first adjusting nut and second adjusting nut that are in the described second bearing pin both sides respectively, and first corresponding with described first adjusting nut respectively nut and second nut corresponding with described second adjusting nut.
Adopt the paver of technique scheme to transfer crown tightly to install, this locking device can guarantee to transfer the distance L between arch back first bearing pin and second bearing pin not change, promptly limited left screed and right screed and transferred relatively rotating behind the arch, leaked the influence that the play that causes is exchanged arch thereby eliminate because of oil cylinder.
In sum, the utility model is that a kind of oil cylinder of eliminating leaks influence and the paver simple in structure, dependable performance exchange arch and transfers crown tightly to install.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is adjusted schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, left side screed 1 and right screed 13 lower ends are hinged by rotating shaft 12, the upper end is connected with hydraulic jack 2, on right screed 13, be provided with second pillar 7, on second pillar 7, be hinged with second bearing pin 8, second bearing pin 8 can be around the rotation of hinged axle center, left side screed 1 is provided with first pillar 14, screw rod 4 one ends are hinged on first pillar 14 by first bearing pin 3, the other end interts on second bearing pin 8, on screw rod 4, be provided with first adjusting nut 6 and second adjusting nut 9 that are in second bearing pin, 8 both sides respectively, and first corresponding with first adjusting nut 6 respectively nut 5 and second nut 10 corresponding with second adjusting nut 9.
Referring to Fig. 1 and Fig. 2, this locking device can guarantee to transfer the distance L of 8 of arch back first bearing pin 3 and second bearing pins not change, promptly limited left screed 1 and right screed 13 and transferred relatively rotating behind the arch, thereby eliminated because of oil cylinder leaks the influence that the play that causes is exchanged arch, concrete operations are as follows:
1. transfer the arch angle to become big (0 →+4%), unclamp second nut 10 and second adjusting nut 9, Push switch makes hydraulic jack 2 (piston rod elongation) drive left screed 1 and right screed 13 12 rotates to suitable camber (scale indication) around the shaft, regulate first adjusting nut 6 respectively and second adjusting nut 9 tightens up second bearing pin 8, and fastening first nut 5 and second nut 10;
2. transfer arch angle diminish (+4% → 0), unclamp first nut 5 and first adjusting nut 6, Push switch makes hydraulic jack 2 (piston rod shortening) drive left screed 1 and right screed 13 12 rotates to suitable camber (scale indication) around the shaft, regulate first adjusting nut 6 respectively and second adjusting nut 9 tightens up second bearing pin 8, and fastening first nut 5 and second nut 10.
Claims (1)
1, a kind of paver transfers crown tightly to install, comprise left screed (1), right screed (13), hydraulic jack (2) and rotating shaft (12), it is characterized in that: described right screed (13) is provided with second pillar (7), on described second pillar (7), be hinged with second bearing pin (8), described left screed (1) is provided with first pillar (14), screw rod (4) one ends are hinged on described first pillar (14) by first bearing pin (3), the other end interts on described second bearing pin (8), on described screw rod (4), be provided with first adjusting nut (6) and second adjusting nut (9) that are in described second bearing pin (8) both sides respectively, and corresponding with described first adjusting nut (6) respectively first nut (5) and second nut (10) corresponding with described second adjusting nut (9).
