Abstract

The utility model relates to a bracket for a fast changing working device, which belongs to a positioning and locking mechanism and is suitable for working machines, such as loaders, fork loaders, etc. to cause the working devices to be installed on a movable arm and a movable connecting rod. The utility model is mainly composed of an upper bracket plate (4), a left and a right hanging plates (19) and (10), a rocker arm (1) with a handle, a rocker arm (18), a movable lock hook (8), etc. When the working device is installed, a lock pin shaft (3) is drawn out to push forwards and lock the rocker arm (1) with a handle to make a hook mouth (23) open. An upper hook (21) is hooked with an upper pin (2) to lift the movable arm (12) slightly, which cause the lower pin (9) to automatically fall in a fork mouth (22). When the rocker arm (1) with a handle is locked by toggling backwards, the hook mouth (23) can be closed to lock the lower pin (9). When the working device is disassembled, the operation is reverse.

Description

Bracket for fast changing working device

A kind of carriage of quick replacing equipment relates to location and catch gear.Be applicable to that loader, fork installation etc. are installed on various work mechanisms on swing arm and the movable rod with equipment.

Present domestic loader is changed multiple equipment and (is comprised scraper bowl, grabs wooden fork, pallet fork, arm, ejector dozer, high-altitude operation platform ... Deng) following three kinds of methods are arranged:

1. the method for common dismounting and installation: promptly equipment is carried out demolition, installation from loading arm and connecting rod by manually taking out, insert hinge pin.

2. change the method for the forebay of erection work device: promptly the forebay of loader is divided into fixed and movable two parts, and different equipments is joined the movable forebay of a different structure, when changing jobs device, needs to change together with movable forebay.

3. adopt the quick change carriage: this carriage and equipment upper pin joint portion are hook-type, and the bottom is a circular pin hole.When changing equipment, can hook or shirk the upper pin of equipment fast though carriage is risen to the bait, the lower bearing pin of equipment combines with the carriage pin-and-hole, and need rely on and manually take out, bolt axle carries out demolition, installation.

Above-mentioned the 1st, 2 kind of method are operated cumbersomely, heavy, often need by means of weight-lifting equipment, and it is slow to change equipment, uses very inconvenient.Though the 3rd kind of method can be removed weight-lifting equipment and part from and be improved the equipment condition that changes the outfit, but because of the lower bearing pin of equipment and pin-and-hole at the construction field (site) often by fouls such as earth stain, the embedding wedge, the dismounting that therefore makes lower bearing pin is difficulty, and is still more time-consuming, effort, the purpose of out of reach real " fast ".

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of carriage that can really change equipment fast is provided, and a main frame is added behind the multiple equipment have multiple function.

The utility model is achieved in that

Pop-up frame plate (4) has the semicircle that matches with upper pin (2) rise to the bait (21).The lower end of left and right link plate (19), (10) has the semi-round prong (22) that matches with bearing pin (9).The front end of movable latch hook (8) has the mouth of hook (23) of the circular arc that matches with bearing pin (9), and top has eccentric slot (25).Pop-up frame plate (4) and left and right link plate (19), (10) all are fixedly connected with crossbeam (6).Pop-up frame plate (4) is movably hinged by connecting rod pin (14) and connecting rod (13).Left and right link plate (19), (10) are movably hinged by swing arm pin (11) and swing arm (12).Band handle rocking arm (1), rocking arm (18) connect with rocker shaft (5) by key (16) respectively.Left and right link plate (19), (10) have hole (24), and rocker shaft (5) is contained in the hole (24) of left and right link plate (19), (10) by bearing carrier ring (15).Crossbeam (6) has through hole (20), and rocker shaft (5) is in the through hole (20) of crossbeam (6); Two fingers (7) respectively with band handle rocking arm (1), rocking arm (18) rigid attachment.Two fingers (7) running-fit is in the eccentric notch (25) of two movable latch hooks (8).Two movable latch hooks (8) are movably hinged with left and right link plate (19), (10) respectively by bearing carrier ring (17), swing arm pin (11).Band handle rocking arm (1), left link plate (19) have lock hole (26), (27), (28).Locking bearing pin (3) passes lock hole (26), (27) or (26), (28).

Accompanying drawing 1 is a constructional drawing of the present utility model.

Accompanying drawing 2 is left view and B-B part sectional views of accompanying drawing 1.

Now in conjunction with the accompanying drawings working process of the present utility model is described below:

When for example the scraper bowl of loader being replaced with pallet fork, extract locking bearing pin (3), promote band handle rocking arm (1) forward, finger (7) is promptly around rocker shaft (5) back pendulum, movable latch hook (8) then moving arm pin (11) rotates, open to the mouth of hook (23), will lock again in lock hole (26) that bearing pin (3) inserts band handle rocking arm (1) and left link plate (19), (28).Control link (13) leans forward rise to the bait (21) of pop-up frame plate (4), treat that the rising to the bait of pop-up frame plate (4) (21) breaks away from the upper pin (2) of scraper bowl of loader after, the loader that falls back, scraper bowl promptly unloads automatically.After aiming at and hook the upper pin (2) of pallet fork with rise to the bait (21) that are about to bracket plate (4), slightly mention swing arm (12), the downside pin of pallet fork (9) promptly falls in the semi-round prong (22) of left and right link plate (19), (10) automatically.Extract locking bearing pin (3) this moment, pull band handle rocking arm (1) backward, the mouth of hook (23) of movable latch hook (8) is with finger (7) forward swing, hook downside pin (9) from top and the place ahead, to lock bearing pin (3) insertion again and be with in the lock hole (26) of handle rocking arm (1) and left link plate (19), (27), then scraper bowl is exchanged goods to pitch and is finished.

The utility model is compared with the prior art: existing quick-changing mechanism is changed equipment and is needed tens of minutes to several hours, some also need by means of crane gear. And the utility model only needs tens of seconds when changing equipment, and does not want any crane gear, can be operated by driver one people, has greatly improved working condition, has improved operating efficiency.

The utility model is as being used in combination with loading machine, fork installation etc., can the multiple equipment of quick-replaceable, reach the purpose of a tractor serves several purposes.

The utlity model has that to change equipment quick, easy to operate, locking is reliable, the advantages such as simple in structure, compactness.
