Abstract

The invention discloses an automatic unhooking and hooking device which comprises an unhooking and hooking mechanism and a connecting mechanism. The unhooking and hooking mechanism comprises a hydraulic cylinder which is connected with limit connecting rods, the lower end of each limit connecting rod is provided with a limit pin shaft, the end of a piston rod of the hydraulic cylinder is hinged to a lifting hook through a bushing and a pin shaft, limit pieces are arranged at the upper end of the lifting hook, the unhook and hook mechanism is connected with a guide cylinder through a spring, and the connecting mechanism penetrates the guide cylinder to be connected with the unhooking and hooking mechanism. The hook allows to be pulled to move with no need for manual operation during unhooking, remote control is adopted, and operational security can be increased; a hammer descends synchronously with the hook, impact on the device is small, loss is low, swing scope is low and high in operation efficiency.

Description

A kind of automatic trip hooking device

Technical field

Patent of the present invention belongs to technical field of engineering machinery, is specifically related to a kind of geotechnical engineering construction equipment that extension is tight and disengagement is moved that can be used for hammer.

Background technology

Tamping machine equipment in operation process, the action that the extension that need to repeat frequently hammer ram is tight, hammer ram is promoted to certain altitude, hammer is thrown off.At present, the common crawler crane pattern that hammer ram operation adopts, which is provided with the mechanical lever locking device of controlling suspension hook rotation.When operation, manual operation hook device hook, the hammer ram that hoists, lever outer end is connected with main frame by wire rope.Arrive after setting height, wire rope is tightened, the pull lever position that goes out of lock, and suspension hook rotation, realizes rammer unhooking, free-falling.When the method breaks off relations, hammer ram separates slowly with suspension hook, makes suspension hook and boom device produce very large swing, reduces the life-span of associated mechanisms, suspension hook mouth of hook serious wear; Need the artificial hook-hanging motion that carries out, work under hard conditions and danger; Rammer unhooking need to be wire rope, adjusts hammer ram height inconvenience, and wire rope easily pulls hammer ram and departs from both allocations, equipment availability inefficiency.

Summary of the invention

The technical problem to be solved in the present invention be tamping machine swing while breaking off relations large, dangerous large, efficiency is low, and a kind of automatic trip hooking device that can reduce swing dynamics, job safety, increase work efficiency is provided.

Technical scheme of the present invention realizes in the following manner: a kind of automatic trip hooking device, comprise hanger casting mechanism and bindiny mechanism, described hanger casting mechanism comprises hydraulic jack, hydraulic jack is connected with spacing connecting rod, the lower end of spacing connecting rod is provided with spacing bearing pin, and the piston rod end of hydraulic jack is hinged and connected by axle sleeve, bearing pin and suspension hook, and the upper end of suspension hook is provided with locating part, hanger casting mechanism is connected with guide cylinder by spring, and bindiny mechanism is connected with hanger casting mechanism through after guide cylinder.

Described bindiny mechanism comprises connector and is connected pressing plate, and guide cylinder inside is provided with the lower pilot hole of taper and the upper pilot hole of taper.

The present invention does not need to pull manually hook-hanging motion in unhook process, by remote control control, increases operational security.It is synchronous that hammer body falls and suspension hook falls, and equipment impacts little, and loss is little, amplitude of fluctuation is little, and operating efficiency is high.

Detailed description of the invention

As shown in drawings, a kind of automatic trip hooking device, comprise hanger casting mechanism and bindiny mechanism, described hanger casting mechanism comprises hydraulic jack 1, and hydraulic jack 1 is connected with spacing connecting rod 2 by bolt 7, and the lower end of spacing connecting rod 2 is provided with spacing bearing pin 9, the piston rod end of hydraulic jack 1 is hinged and connected with suspension hook 4 by axle sleeve 8, bearing pin 3, the upper end of suspension hook 4 is provided with locating part 13, and hanger casting mechanism is connected with guide cylinder 11 by spring 10, and bindiny mechanism is connected with hanger casting mechanism through after guide cylinder 11.

Described bindiny mechanism comprises connector 5 and is connected pressing plate 6, and guide cylinder 11 inside are provided with the lower pilot hole 11-1 of taper and the upper pilot hole 11-2 of taper.Connecting pressing plate 6 is connected with hammer ram 12.Because the area of lower pilot hole 11-1 is larger, can contain larger scope, when connector 5 is placed on ground time, as long as connector touches the inwall of lower pilot hole 11-1, just can under guiding to effect, it enter in suspension hook 4.On hammer ram 12, understand frequent foundry loam soil etc., after pilot hole 11-2 is set, can prevent that earth from stopping up, and can also prevent from when hammer ram 12 from falling being offset.

The course of work of the present invention is as follows: when hook, guide suspension hook 4 and connector 5 aligned position by guide cylinder taper surface, transferring haulage cable moves down the related fixture entirety of suspension hook 4, make connector 5 enter suspension hook 4 along lower pilot hole 11-1, thereby realize hook-hanging motion.While breaking off relations action, wireless signal control unloader, realizes cylinder rod chamber off-load, hydraulic jack 1 extends, and suspension hook 4 moves downward, and in the time that locating part 13 touches the spacing bearing pin 9 being arranged in spacing connecting rod 2, two suspension hooks 4 open relatively, connector 5 is thrown off, realize the action of breaking off relations.Then hydraulic jack 1 resets under the effect of spring 10, prepares second leg action.

The present invention is applicable in multiple dynamic consolidation construction operation.Hook-hanging motion relies on guide cylinder guiding, allows in a big way, to carry out hook-hanging motion, when when hook-hanging motion, hammer ram connector is opened to both sides, is connected with spacing connecting rod 2 nothings, unobstructed, relies on the deadweight of hammer ram connector to close, and links up with simple and reliable.While breaking off relations action, hammer ram connector whereabouts and hook whereabouts are synchronous, and connector 5 weares and teares little, and the whole device of dropping process impacts little, use manpower and material resources sparingly, and increase working security has greater advantage aspect increasing work efficiency.

The present invention is electricity, liquid, mechanical integrated system.Hook-hanging motion relies on hook deadweight automatically to realize, and the action wireless remote control that breaks off relations is realized.
