Background technology
At present, the heating pad wall of flexible pavement microwave curing car has adopted a kind of suspension type motion, and this mechanism adopts hydraulic-driven; A part is positioned at the rear portion, compartment, a part is installed in the automobile tail below, because the total weight of heating pad wall is all supported by its motion, the mechanism that is positioned at the automobile tail below is longer apart from the arm of force of axis of rotation, makes heating pad wall have unstability and travel safety problem.At this problem, manufacturing enterprise adopts latch assembly to lock the structure of motion, but because this latch adopts manually-operated, and operability is poor, and operating personnel need certain labour intensity.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of not need manual operation can realize automatic locking, alleviates the heating pad wall motion that is used for microwave road maintaining vehicle of labor intensity of operating personnel.
Structural representation of the present utility model as shown in Figure 1, include the turning arm (5) that supports heater (1), drive rotary components (4) and drive rotary oil cylinder (6), turning arm (5) is connected with driving rotary components (4), driving rotary components (4) is connected with the piston that drives rotary oil cylinder (6), wherein be provided with forced locking device A between turning arm (5) and the driving rotary components (4), it includes fixed head (10), location-plate (9) and latch assembly (11), wherein latch assembly (11) comprises oil cylinder (18), locking pin (8) and place back-moving spring (14) in the oil cylinder (18), locking pin (8) is packed on the piston (18A) of oil cylinder (18), oil cylinder (18) is packed on the location-plate (9), fixed head (10) is provided with the lockhole (17) that locking pin (8) is inserted, and fixed head (10) is packed on the turning arm (5).
Above-mentioned back-moving spring (14) is installed in the bottom of oil cylinder (18).
The end of said fixing plate (10) is made and is ramp structure.
The oil inlet and outlet (16) of above-mentioned oil cylinder (18) is arranged between the oil cylinder seat (12) of oil cylinder piston (18A) and oil cylinder (18).
The bottom of above-mentioned oil cylinder (18) has airport (15).
Above-mentioned oil cylinder (18) and driving rotary oil cylinder (6) interlock.
Above-mentioned oil cylinder (18) is packed on the location-plate (9) by junction plate (13) and screw.
The utility model is owing to adopt locking cylinder and the structure of locking pin realization automatic locking, and therefore, it does not need manual operation can realize locking, thereby alleviates labor intensity of operating personnel.The utility model is that a kind of design is ingenious, simple in structure, the convenient and practical heating pad wall motion that is used for microwave road maintaining vehicle.

The specific embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include the turning arm 5 that supports heater 1, drive rotary components 4 and drive rotary oil cylinder 6, wherein turning arm 5 is connected with driving rotary components 4, driving rotary components 4 is connected with the piston that drives rotary oil cylinder 6, it is characterized in that turning arm 5 and drive between the rotary components 4 being provided with forced locking device A, it includes fixed head 10, location-plate 9 and latch assembly 11, wherein latch assembly 11 comprises oil cylinder 18, locking pin 8 and place back-moving spring 14 in the oil cylinder 18, locking pin 8 is packed on the piston 18A of oil cylinder 18, oil cylinder 18 is packed on the location-plate 9, fixed head 10 is provided with the lockhole 17 that locking pin 8 is inserted, and fixed head 10 is packed on the turning arm 5.
In the present embodiment, above-mentioned back-moving spring 14 is installed in the bottom of oil cylinder 18.The oil inlet and outlet 16 of above-mentioned oil cylinder 18 is arranged between the oil cylinder seat 12 of oil cylinder piston 18A and oil cylinder 18.The end of said fixing plate 10 is made and is ramp structure.
For guaranteeing the capable of expansion and contraction of oil cylinder piston 18A, the bottom of above-mentioned oil cylinder 18 has airport 15.
For ease of control, above-mentioned oil cylinder 18 and 6 interlocks of driving rotary oil cylinder.
For ease of processing and installation, above-mentioned oil cylinder 18 is packed on the location-plate 9 by junction plate 13 and screw.
The utility model is such realization: before heater 1 preparation, hydraulic circuit is opened the beginning oil-feed, the oil cylinder 18 of latch assembly 11 is descending, driving locking pin 8 withdraws from the lockhole 17 on the fixed head 10, finish and unblank, the driving rotary oil cylinder 6 that drives rotary components 4 is simultaneously also opened, and begins withdrawal, and turning arm 5 screws off a heater 1 and drops to the road surface and carry out operation.Operation finishes, the driving rotary oil cylinder 6 of driving rotary components 4 is opened and is stretched out, turning arm 5 screwed on heater is erect, the lockhole 17 of locking pin 8 secured in alignment plates 10 drives rotary oil cylinder 6 and drains the oil, under back-moving spring 14 effects, the piston 18A of oil cylinder 18 is up, drive locking pin 8 motions, insert the lockhole 17 of fixed head 10, finish locking.
