According to the technical scheme, the active unhooking device comprises a lifting pulley, a main hook head and an auxiliary hook head, wherein the lifting pulley is fixed to a side board of the unhooking device, the main hook head and the auxiliary hook head are fixed to the lower portion of the side board of the unhooking device, and the main hook head can be connected with the auxiliary hook head in a rotating mode. The active unhooking device is characterized in that a main power cylinder is fixed to the side board of the unhooking device, a piston of the main power cylinder can be connected with a connecting rod a and a connecting rod b in a rotating mode, the other end of the connecting rod a is fixed to the side board of the unhooking device in a rotatable mode, the other end of the connecting rod b is fixed to the main hook head in a rotatable mode, an auxiliary power cylinder is further fixed to the side board of the unhooking device, the auxiliary power cylinder is connected with a stop block through a lever, the stop block is located between guide rails fixed to the side board of the unhooking device, sliding rails are arranged below the stop block, the sliding rails are fixed to the side board of the unhooking device, a sliding block is installed on the sliding rails, and the sliding block is connected with the auxiliary hook head. The active unhooking device is mainly suitable for a dynamic compaction machine.
Description
Technical field
The utility model relates to a kind of suspender, particularly a kind of active detacher.
Background technology
The strong rammer detacher of main flow is all traditional passive unhook mode at present, by be connected on dynamic compaction machinery turntable and detacher on wire rope, when detacher is thus lifted to the height of setting, wire rope is tightened up, and now wire rope pulls the leverage on detacher to realize unhook.Because its unhook is all based on lever principle, can only control the action of breaking off relations, gib head automatically resets after unhook, can not people for controlling, while again linking up with, all need that personnel are auxiliary to be linked up with at every turn.
Summary of the invention
The purpose of this utility model is to provide a kind of active detacher, mainly solves the technical problem that existing passive unhook mode needs the auxiliary hook of personnel.
The technical solution of the utility model is: a kind of active detacher, comprise and be fixed on lifting tackle on detacher side plate, with the main hook head and the auxiliary hook head that are fixed on detacher side plate bottom, main hook head and auxiliary hook head are rotatably connected, it is characterized in that fixing active force cylinder on detacher side plate, active force cylinder piston be rotatably connected connecting rod a and connecting rod b, the connecting rod a other end is rotatably fixed on detacher side plate, and the other end of connecting rod b is rotatably fixed on main hook head; On detacher side plate, be also fixed with secondary power cylinder, secondary power cylinder connects block by lever, described block is between the guide rail being fixed on detacher side plate, below block, be provided with slide rail, described slide rail is fixed on detacher side plate, slide block is housed on slide rail, and described slide block is connected with auxiliary hook head.Described master/secondary power cylinder is hydraulic jack or pneumatic linear actuator.
The beneficial effects of the utility model are: main hook head, detacher side plate and two connecting rods form four-bar mechanism, by power cylinder for this reason in four-bar mechanism the link member except detacher side plate power is provided, main hook head is rotated around the tie point of itself and detacher side plate.Main hook head, auxiliary hook head, guide rail and slide block form slider-crank mechanism, and the rotation by main hook head for this reason slider-crank mechanism provides power.When promoting hammer ram, the glide direction motion when slide block in slider-crank mechanism has block can stop slide block towards unhook; When breaking off relations, this block is moved by the power that secondary power cylinder provided, the glide direction motion while making it no longer stop slide block towards unhook.The utility model is realized the reset of detacher gib head and the people of unhook for controlling by power cylinder, can reduce the number of times of the auxiliary hook of hook personnel.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.

Fig. 3 is the utility model hook schematic diagram.
In figure: 1-lifting tackle, 2-detacher side plate, 3-guide rail, 4-connecting rod a, 5-connecting rod b, 6-main hook head, 7-auxiliary hook head, 8-active force cylinder, the secondary power cylinder of 9-, 10-lever, 11-block, 12-slide rail, 13-slide block, 14-hammer ram hammer handle.
The specific embodiment
With reference to Fig. 1, a kind of active detacher, comprise and be fixed on lifting tackle 1 on detacher side plate, with the main hook head 6 and the auxiliary hook head 7 that are fixed on detacher side plate 2 bottoms, main hook head 6 and auxiliary hook head 7 are rotatably connected, fixing active force cylinder 8 on detacher side plate 2, the piston of active force cylinder 8 be rotatably connected connecting rod a4 and connecting rod b5, the connecting rod a4 other end is rotatably fixed on detacher side plate 2, and the other end of connecting rod b5 is rotatably fixed on main hook head 6; On detacher side plate 2, be also fixed with secondary power cylinder 9, secondary power cylinder 9 connects block 11 by lever 10, described block 11 is between the guide rail 3 being fixed on detacher side plate, below block 11, be provided with slide rail 12, described slide rail 12 is fixed on detacher side plate 2, slide block 13 is housed on slide rail, and described slide block 13 is connected with auxiliary hook head 7.Described master/secondary power cylinder is hydraulic jack or pneumatic linear actuator.
With reference to Fig. 2, while breaking off relations action, people controls the piston-retraction of active force cylinder 8 and the piston of secondary power cylinder 9 stretches out, block 11 moves up under the active force of lever 10, when block 11 departs from slide block 13, under the Action of Gravity Field of active force cylinder 8 withdrawal forces or hammer ram, four-bar mechanism action, main hook head 6 clockwise rotates, slider-crank mechanism action simultaneously, auxiliary hook head 7 moves right together with slide rail 12, and rotates counterclockwise, open the closed area that hammer ram hammer handle 14 places are formed by main hook head 6 and auxiliary hook head 7, now completes unhook.
With reference to Fig. 3, during hook-hanging motion, people is that the piston of controlling active force cylinder 8 stretches out, four-bar mechanism action, main hook head 6 rotates counterclockwise, slider-crank mechanism action, and auxiliary hook head 7 is moved to the left together with slide rail 12, and clockwise rotate, the closed area being formed by main hook head 6 and auxiliary hook head 7 at hammer ram hammer handle 14 places, the piston-retraction of secondary power cylinder 9, block 11 moves down under lever 10 active forces, until block 11 fully contacts with slide block 13, now complete hook.
