By means of controlling the shrinking of the oil cylinder by the manual oil pump and the acting force of the oil cylinder piston rod, and under the matching of the component such as the master bracket, the secondary bracket, etc., the hinged hole of the secondary jib loading boom is easily and automatically lined up with the hinged hole of the main jib loading boom, and the mounting of the secondary jib loading boom is convenient, timesaving, labor saving, high efficient and safe operating. The utility model is suitable for the assembling of the secondary jib loading boom and the main jib loading boom of the tyre crane.
Description
Technical field
Erecting device when the utility model relates to a kind of car hosit auxiliary cargo boom and the assembling of main crane arm.
Background technology
The auxiliary cargo boom of car hosit and main crane arm are the four hinges assembling bonded assemblys by main crane arm head.Assembling is during auxiliary cargo boom, normally earlier around the fixed connection shaft revolute pair crane arm of auxiliary cargo boom and main crane arm side, with the hinge of the hinge of auxiliary cargo boom end one side and main crane arm head one side hinged on.Pull down the fixed connection shaft of side then, around main crane arm head hinge revolute pair crane arm, the hinge of hinged opposite side.In opposite side hinge articulated procedures, owing to be subjected to many-sided influences such as auxiliary cargo boom deadweight, manufacturing errors, the auxiliary cargo boom hinge hole is difficult to align with main crane arm hinge hole, and it is very difficult that bearing pin is installed.Prior art is artificial centering, operating difficulties, and efficient is low.For large-tonnage hoisting crane more than 80 tons because higher and auxiliary cargo boom length of car load height and weight are bigger, install this bearing pin more time-consuming, require great effort and operate dangerous.
Summary of the invention
The purpose of this utility model is that a kind of auxiliary cargo boom auxiliary power erecting device will be provided, and this erecting device is easy to use, safe and efficiency of assembling is high.
The purpose of this utility model is achieved in that this erecting device comprises main support, link span, bearing pin, Spring Card, assistant support, oil cylinder and hand oil pump, main support is welded on main crane arm head, the main support head is provided with main aperture, assistant support is welded on the auxiliary cargo boom head, the assistant support head is provided with pin shaft hole, assistant support and oil cylinder are positioned at the link span inboard, the link span front end is provided with connecting bore, the link span front portion is connected with seesaw with holes, the hole of seesaw links to each other with the pin shaft hole of Spring Card with the assistant support head by bearing pin, the rear end of link span links to each other with the rear end of oil cylinder, and the front end of oil cylinder links to each other with the back of assistant support, and oil cylinder is connected with hand oil pump.
The utility model utilizes the flexible of hand oil pump control oil cylinder, application force by the oil cylinder piston bar, under the cooperation of parts such as main support, assistant support, make the auxiliary cargo boom hinge hole be easy to align automatically with main crane arm hinge hole, install auxiliary cargo boom make things convenient for, save time, laborsaving, efficiency of assembling is high and safety of operation.Be applicable to the assembling of car hosit auxiliary cargo boom and main crane arm.
Description of drawings
Fig. 1 is the constructional drawing of an embodiment of the present utility model.
Fig. 2 is link span and the assistant support bonded assembly birds-eye view among Fig. 1.
1. main supports among the figure, 2. link span, 3. bearing pin, 4. Spring Card, 5. assistant support, 6. oil cylinder, 7. hand oil pump, 8. seesaw, 9. connecting bore, 10. auxiliary cargo boom, 11. main crane arms.
The specific embodiment
In Fig. 1 and Fig. 2, main support 1 is welded on main crane arm 11 heads, and main support 1 head is provided with main aperture.Assistant support 5 is welded on auxiliary cargo boom 10 heads, and assistant support 5 heads are provided with pin shaft hole.Assistant support 5 and oil cylinder 6 are positioned at link span 2 inboards.Link span 2 front ends are provided with connecting bore 9, and the main aperture in the accompanying drawing has overlapped with connecting bore 9.The front portion of link span 2 is connected with seesaw with holes 8, and the hole of seesaw 8 links to each other with the pin shaft hole of Spring Card 4 with assistant support 5 heads by bearing pin 3, and the rear end of link span 2 links to each other with the rear end of oil cylinder 6.The front end of oil cylinder 6 links to each other with the back of assistant support 5, and oil cylinder 6 is connected with hand oil pump 7.Hand oil pump 7 links to each other with auxiliary cargo boom 10.
On assembling auxiliary cargo boom 10 is hinged behind the hinge of a side, again around this hinge revolute pair crane arm 10, the hinge of hinged opposite side.When the hinge hole of opposite side hinge master crane arm 11 does not also align with the hinge hole of auxiliary cargo boom 10, the connecting bore on the link span 29 is alignd with main aperture on the main support 1.At this moment, pull down bearing pin 3 and Spring Card 4 and be assemblied in connecting bore 9 and main aperture place.Handle hand oil pump 7, pressure oil enters oil cylinder 6, the piston rod that promotes oil cylinder 6 stretches out, piston rod promotes assistant support 5 and travels forward, shorten the distance between main crane arm 11 and auxiliary cargo boom 10 hinge holes, hinge hole up to auxiliary cargo boom 10 aligns with the hinge hole of main crane arm 11, installs to connect bearing pin.
