Abstract
This utility model discloses an auxiliary landing leg structure of a bridge erecting machine, wherein one end is articulated with the trunk beam of the bridge erecting machine through an upper transverse beam; the other end is articulated with a support through a support steel pin; the auxiliary landing leg structure disclosed by this utility model is composed of a plurality of telescopic joints which are sleeved and jointed mutually; the telescopic joints are structure in a circular pipe shape; a plurality of height adjusting holes are formed on the surface of the circular pipe; bolts are matched with the height adjusting holes; the bolts pass through the height adjusting holes relatively to two adjacent telescopic joints so as to connect the two telescopic joints; the telescopic joints of the auxiliary landing leg structure disclosed by this utility model are structured in a circular pipe shape; the adjacent telescopic joints are connected mutually through the bolts and the height adjusting holes; compared with a traditional landing leg structure, the auxiliary landing leg structure disclosed by this utility model is not only characterized by easy installation, simple processing procedure, but also flexible landing leg height adjustment, safe and reliable use.
Description
Technical field
The utility model relates to a kind of equipment of auxiliary bridge formation machine via hole, especially relates to the auxiliary leg structure of a kind of bridge formation machine.
Background technology
At present, the bridge formation machine has become and has set up road bridge, conventional railway bridge; The visitor is the requisite engineering equipment of railway bridge specially; The bridge formation machine is exactly that prefabricated beam sheet is placed into the equipment that prefabricated bridge pier gets on, and its major function is that the beam sheet is mentioned, and puts down after being transported to the position then.But bridge formation machine and crane in general sense are very different, and the condition of its requirement is harsh, and has traveling on the beam sheet, perhaps cries vertical shift.For guarantee to build bridge can safety and stability via hole, the bridge formation machine needs the auxiliary of supporting leg when via hole, the expansion coupling of the supporting leg of traditional auxiliary bridge formation machine via hole is square expansion coupling, obviously adopts this leg structure to exist height of landing leg to be difficult for regulating; Difficulty of processing is big, and inconvenience and the low shortcoming of safety factor are installed.
The utility model content
The purpose of the utility model is to provide a kind of bridge formation machine to assist leg structure, and it has height of landing leg can flexible, and manufacturing procedure is simple, is easy to safe and reliable characteristics are installed.
The purpose of the utility model is through realizing with below technology case:
A kind of bridge formation machine is assisted leg structure, and the one of which end is articulated on the trunk beam of bridge formation machine through top rail, and the other end is articulated on the bearing through the bearing steel pin; Wherein, The auxiliary leg structure of said bridge formation machine is spliced by several expansion coupling suits, and said expansion coupling is a circular tube structure, and said pipe surface all has several height adjustment holes; The engagement height adjustment hole is provided with latch, and said latch passes the connection of the corresponding height adjustment hole of adjacent two expansion couplings with two expansion couplings.
Especially, the auxiliary leg structure of said bridge formation machine is spliced by 4 expansion coupling suits.
The beneficial effect of the utility model does, the auxiliary leg structure of said bridge formation machine is spliced by several expansion coupling suits, and said expansion coupling is a circular tube structure, is connected with adjustment hole highly through latch between the adjacent expansion joint.Compare with traditional leg structure and not only to be easy to install, manufacturing procedure is simple; And it is flexible, safe and reliable to regulate height of landing leg.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the auxiliary leg structure of the utility model bridge formation machine;
Fig. 2 is the sectional drawing of the auxiliary leg structure of the utility model bridge formation machine.
Among the figure:
1, trunk beam; 2, top rail; 3, hinged seat; 4, expansion coupling; 5, latch; 6, bearing; 7, height adjustment hole; 8, bearing steel pin.
The specific embodiment
Please with reference to Fig. 1 and shown in Figure 2, Fig. 1 is the structural representation of the auxiliary leg structure of the utility model bridge formation machine; Fig. 2 is the sectional drawing of the auxiliary leg structure of the utility model bridge formation machine.
In present embodiment; Being spliced of the auxiliary leg structure of said bridge formation machine by four expansion coupling 4 suits, said expansion coupling 4 is a circular tube structure, said pipe surface all has several height adjustment holes 7; Engagement height adjustment hole 7 is provided with latch 5; Said latch 5 passes the connection of the corresponding height adjustment hole 7 of adjacent two expansion couplings 4 with two expansion couplings 4, and an end of the auxiliary leg structure of said bridge formation machine is articulated on the bearing 6 through bearing steel pin 8, and the other end is provided with top rail 2; Said top rail 2 is provided with hinged seat 3, will assist supporting leg to be articulated on the trunk beam 1 of bridge formation machine through hinged seat 3.
The auxiliary leg structure of said bridge formation machine is spliced by several expansion coupling suits, and said expansion coupling is a circular tube structure, is connected with the height adjustment hole through latch between the adjacent expansion joint.Compare with traditional leg structure and not only to be easy to install, manufacturing procedure is simple; And it is flexible, safe and reliable to regulate height of landing leg.
Claims (2)
