Abstract
The utility model discloses a three-pin-fixed type foldable H-beam device, which comprises a base. The base is hinged with supporting legs through hinge pins, the base is provided with a rotating pin hole and two fixed pin holes, and the supporting legs are provided with pin holes corresponding to the rotating pin hole and the fixed pin holes. According to the three-pin-fixed type foldable H-beam device, a lower base H-beam is designed to be in foldable structure, and on the premise of ensuring the structural strength of a large-tonnage crane in working, H supporting legs are folded to the lateral side surfaces of a track frame after orbital transfer, thereby achieving the aim of narrowing the width of the whole machine.
Description
Technical field
The utility model relates to the above large-tonnage hydraulic crawler crane of a kind of 300t, is specifically related to the H type beam that a kind of hydraulic crawler crane is used.
Background technology
The rugged in the open air for a long time mountain region of crawler crane work in the widespread usage of hydraulic crawler crane in China's large and medium-sized projects, particularly wind-powered electricity generation installation project in recent years, its operating mode road crossing ability during to the hoisting crane inoperative requires increasingly high.Hoisting crane uses the client to hope to accomplish and after a wind-powered electricity generation is installed hoisting crane is driven to another seat in the plane of closing on, can save a lot of times like this, labour power and dismounting cost of transportation.A lot of construction machinery and equipment manufacturing firms become the solution that rail goes in order to satisfy the requirement of crossing ability when having adopted inoperative.Though becoming the large-tonnage hydraulic crawler crane gauge of rail has now on the market diminished; But the width of H type beam does not change; Generally all cannot pass through running into the narrow lacet or the road that caves in; Need complete machine disintegration, transportation to re-assembly again, therefore, become rail on this kind degree and lost meaning.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art; The collapsible H type of a kind of three pin fixed types boom device is provided; Can guarantee that crawler crane has under enough structural strength prerequisites, make that the complete machine width can shorten when becoming the rail walking, the crossing ability when increasing walking.
The technical scheme of the utility model realizes in the following manner: the collapsible H boom device of a kind of three pin fixed types; Comprise base; Base and supporting leg are hinged and connected through fixed pin shaft and rotary pin shaft; Said base is provided with a rotation pin-and-hole and two fixed pin holes, and supporting leg is provided with and rotates pin-and-hole, the cooresponding pin-and-hole of fixed pin holes.
One side of said supporting leg is box typed structure, opposite side is provided with resistance to compression boss, support rim and tension plate, and base is provided with first boss, second boss, and base is connected with staggered up and down the inlaying of supporting leg.
The utility model base H type beam of will getting off is designed to folding structure, under the prerequisite of the structural strength when guaranteeing hoister in large tonnage work, the H supporting leg is folded into the track frame side after becoming rail, dwindles the wide purpose of complete machine thereby reach.

The specific embodiment
Shown in Fig. 1 ~ 4; The collapsible H type of a kind of three pin fixed types boom device; Comprise base 1; Base 1 links to each other through fixed pin shaft 6, rotary pin shaft 5 hinged inlaying with supporting leg 4, and said base 1 is provided with a rotation pin-and-hole 2 and two fixed pin holes 3, and supporting leg 4 is provided with and rotates pin-and-hole 2, fixed pin holes 3 cooresponding pin-and-holes.
One side of said supporting leg 4 is box typed structure, opposite side is provided with resistance to compression boss 4-1, support rim 4-2 and tension plate 4-3; Base 1 is provided with the first boss 1-1, the second boss 1-2; When using, base 1 interlocks up and down to inlay to be connected with supporting leg 4 and can guarantee that like this single unit system has enough structural strengths when working.
As shown in Figure 3 during lifting work in the utility model: rotary pin shaft 5 is inserted in the rotation pin-and-hole 2, fixed pin shaft 6 is inserted in the fixed pin holes 3, is stressedly mainly born by fixed pin shaft 6; The utility model folding process is as shown in Figure 4; Fixed pin shaft 6 is removed; Make supporting leg 4 rotate around rotary pin shaft 5, supporting leg 4 is close to the track frame outside, and it is minimum and need not dismantle caterpillar block and just can set pin be taken out to guarantee to become behind the rail integral width like this; Integral width diminishes after becoming rail, and crossing ability is better.
In the utility model, base 1 adopts box typed structure to be welded with supporting leg 4 by steel plate, and fixed pin shaft 6 adopts the good steel heat of performance to handle with rotary pin shaft 5 and forms.Only need three bearing pins be connected together base 1 with supporting leg 4 during assembling and get final product; Only need when becoming rail set pin 6 is taken out, supporting leg 4 is folded into track frame one side can realize change rail truly.
Can find out like Fig. 5 ~ 9; Compare with change flange of rail seat of the prior art; The utility model can improve the crossing ability of complete machine on winding road, depression road; Hoisting crane with the 8700mm width is an example, and the maximum width that existing variable flange of rail seat becomes behind the rail has only 6350mm into the maximum width that 7800mm the utility model becomes behind the rail.
