Abstract
The utility model relates to a folding engine hoist, which is composed of a main beam 25, a pair of supporting arms 13, a pair of folding legs 1, 22, a pair of pin shafts 15, a lifting arm 5, a lifting hook 7, an upright column 3, an upright column transverse beam 17, a jack 9, a jacking bracket 21 and rollers 2, 12, 24. The utility model is characterized in that the middle parts of the pair of supporting arms are respectively provided with a group of fixed plates 14 additionally, the upper part of the fixed plate 14 is provided with socket pin holes 27, and the lower part is provided with pin shaft holes 28. The base parts of the pair of folding legs 1, 22 are respectively provided with socket pin holes 19 and pin shaft holes 18 additionally corresponding to the socket pin holes 27 and the pin shaft holes 28. Socket pins 16 are inserted in the socket pin holes 27, 19, and pin shafts 15 are inserted in the pin shaft holes 28, 18. The utility model has the advantage that no shaking or even dumping can occur due to the pair of stable folding legs on the supporting arms.
Description
The utility model relates to a kind of collapsible driving engine loop wheel machine, is the improvement to existing collapsible driving engine loop wheel machine.
Existing collapsible driving engine loop wheel machine, a pair of folding leg of being located on two supporting arms anxiety of toppling over very easily occurs rocking even existing because of poor stability under folding (also claiming to draw in) state.Its reason is that folding leg is connected the shortage reasonableness with the structure of supporting arm: when folding leg is horizontally-arranged, insert in regular turn in the hole that matches with this pin shaft hole on the pin shaft hole of supporting arm end and the folding leg by bearing pin, so that folding leg keeps under extended configuration and being connected of supporting arm, though the connection under this extended configuration can be satisfied operating needs; Yet when folding leg was folding, bearing pin did not insert the folding leg base portion, and only inserted in the pin shaft hole that is opened in the supporting arm middle part, realized blocking a side of folding leg, be difficult to eliminate folding leg rock and might occur topple over phenomenon.
Task of the present utility model be to provide a kind of folding leg under folded state good stability, the collapsible driving engine loop wheel machine that rocks, stop to topple over can not appear.
Task of the present utility model is finished like this, a kind of collapsible driving engine loop wheel machine, by girder 25, a pair of supporting arm 13, a pair of folding leg 1,22, a pair of bearing pin 15, arm 5, suspension hook 7, column 3, stand column and beam 17, jack 9, jacking bracket 21, roller 2,12,24 are formed, characteristics are: each addition of the middle part of a pair of supporting arm 13 has one group of adapter plate 14, adapter plate 14 tops are provided with pin hole 27, and the bottom is provided with pin shaft hole 28; The base portion of a pair of folding leg 1,22 has additional respectively and described pin hole 27, pin shaft hole 28 corresponding pin holes 19, pin shaft hole 18; Plant latch 16 in the pin hole 27,19 inserts bearing pin 15 in the pin shaft hole 28,18.
The utility model has been owing to adopted said structure, when a pair of folding leg 1,22 is folding, as long as latch 16 is inserted pin hole 27,19 in regular turn, and is aided with bearing pin 15 and inserts pin shaft holes 28,18 and just can realize good stability, can not occur rocking and even toppling over.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is the utility model constructional drawing.
A pair of supporting arm 13 base portions of the present utility model are solid mutually with girder 25, and the front end position respectively has groove 29, and a pair of folding leg 1,22 is when horizontally-arranged, and its leg body is positioned at this groove 29 just.Middle part and front end at supporting arm 13 respectively have pin shaft hole 6,11, and pin shaft hole 6 is corresponding with pin shaft hole 28,18 respectively.Fix as soon as bearing pin 15 is inserted to pin shaft hole 28,18,6 in regular turn and adds nut, just can realize the pivot joint of a pair of folding leg 1,22 and a pair of supporting arm 13.The solid suspension hook 7 of one end system of arm 5, the other end is hinged with the top of column 3 by adapter shaft 4, and the bottom of column 3 is solid mutually with the middle part of stand column and beam 17, and two ends of stand column and beam 17 are solid mutually with a pair of supporting arm 13.Jack 9 is located on the jacking bracket 21, and jacking bracket 21 is fixed on the column 3, and the piston tip of jack 9 is connected with arm 5 by little 8.Roller 2,12,24 respectively has a pair of, is located at two ends of a pair of folding leg 1,22 and a pair of supporting arm 13 and girder 25 respectively.
When needing, a pair of folding leg 1,22 of the present utility model is folded state, under this state, latch 16 is inserted in the pin hole 27,19, and by bayonet lock 10 card as in the pin hole on the bayonet lock 10 23, add the pivot joint relation that folding leg 1,22 base portions are made of bearing pin 15 and supporting arm 13, so, than only bearing pin 15 was inserted in the past pin shaft hole on the supporting arms 13 held up the stable and safety of retaining folding leg 1,22 many.And in the time will using the utility model, at first a pair of latch 16 is taken out, make a pair of folding leg 1,22 horizontally-arranged, and insert, until the pin shaft hole 20 that passes on the folding leg 1,22 with the pin shaft hole 11 of a pair of latch 16 on supporting arm 13.With pressing hand 26 pressing jacks 9, the piston of jack 9 just stretches out in oil cylinder then, with jack-up arm 5, thereby the driving engine that is hung on the suspension hook 7 is sling, handling after hours, jack 9 releases, arm 5 tenesmus and drawing in.
