Abstract
The utility model relates to a height-adjustable back supporting mechanism for a bridge erecting machine, which belongs to the back supporting mechanism for bridge erecting devices. The back supporting mechanism comprises a lower cross beam, a connecting beam of a main beam, a seat beam, a walking mechanism, a hydraulic jacking system and an anchorage mechanism, the two ends of the lower cross beam are respectively connected with U-shaped curved legs, the connecting beam of the main beam is connected between the other ends of the two curved legs, the bottom of the lower cross beam is connected with the walking mechanism, the hydraulic jacking system and the anchorage mechanism, and the bottom of one end of the connection of the curved legs and the lower cross beam is connected with the seat beam. The mechanism has the advantages that: the adoption of the hydraulic jacking system can adjust the height of the back supporting mechanism of the bridge erecting machine rapidly, accurately and steadily, thus realizing rapid conversion of two states of erecting and carrying; the U-shaped structure has great structural strength and can bear heavy load steadily and buffer the mechanical impact of the heavy load, thus improving the supporting stability and the adjustment convenience; and the process is simple and is easy to operate, thus reducing the operational trouble and risk.
Description
Technical field
The utility model relates to a kind of back supporting mechanism of bridge support equipment, supporting mechanism behind particularly a kind of adjustable for height bridge formation machine.
Background technology
Present domestic main flow bridge formation machine is 900 tons, and this specification product meets present construction of railways demand, and bridge formation machine principal mode has: truss-like bridge formation machine (no nose girder), nose girder formula bridge formation machine, auxiliary nose girder formula bridge formation machine etc.
Back supporting mechanism is the main load-supporting part of bridge formation machine and vertically moves driving mechanism, adopt the just bent leg structure of " U " type, be made up of removable lower transverse beam, bent leg, running mechanism, hydraulic jacking system etc., the beam of getting in touch of it and girder afterbody is formed " O " type structure again.The flange socket at bent leg place uses high-strength big six-angle spiral to connect.The bridge formation machine is at the design of the size of the precast beam of the high iron wire of certain bar and weight, and the concrete box girder that the supporting mechanism height can only adapt to certain altitude behind the general bridge formation machine passes through.Precast beam height used in later construction increases, if change the height that the back is supported, need redefine overall structure.It weighs more than 600 ton certainly one cover bridge formation machine, and equipment is huge, and system complex is carried out very big change to the back braced structures and will be dropped into a large amount of cranes and transport vehicle, so promptly delays the duration, seriously consumes lot of manpower and material resources again.
The utility model content
The purpose of this utility model is to provide a kind of: supporting mechanism behind the adjustable for height bridge formation machine of supporting mechanism height after can regulating.
The purpose of this utility model is achieved in that this back supporting mechanism comprises: lower transverse beam (1), girder contact beam (6), seat beam (7), running mechanism (8), hydraulic jacking system (9) and anchoring mechanism (10), two ends at lower transverse beam are connected with bent leg respectively, bent leg is " U " type, between the other end of two bent legs, be connected with girder contact beam, be connected with running mechanism (8), hydraulic jacking system (9) and anchoring mechanism (10) in the bottom of lower transverse beam, the bottom of an end that is connected with lower transverse beam at bent leg is connected with seat beam.
Described bent leg comprises bent leg one (2), bent leg two (3), connecting flange (4) and bent leg three (5), bent leg one (2), bent leg two (3), connecting flange (4) and bent leg three (5) are linked in sequence, constitute " U " type, flange is all arranged in the end of bent leg one (2), bent leg two (3), connecting flange (4) and bent leg three (5).
Beneficial effect, owing to adopted such scheme, the lower transverse beam of horizontal structure is adopted in the bottom of back supporting mechanism, makes things convenient for the assembling and the disintegration of bridge formation machine, also is convenient to Beam transportation vehicle simultaneously and packs the bridge formation machine; Lower transverse beam is divided in respect of two cover traveling roller boxs, and each is by a motor-driven, and machine via hole or short distance operation realizes building bridge; Lower transverse beam the right and left is respectively three sections bent legs and one section connecting flange, and the through hole height that changes the bent leg structure of " U " type by the length that changes the connecting flange section sets up with the concrete box girder of realizing differing heights.Realized the height of supporting mechanism behind the bridge formation machine is regulated, reached the purpose of this utility model.
Advantage: adopt hydraulic jacking system, can quick and precisely regulate supporting mechanism height behind the bridge formation machine stably, realize the conversion of frame fortune two states fast, " U " type structural strength is big, can bear the mechanical shock of heavy duty and buffering heavy duty stably, has increased the stability that supports, the convenience of regulating, operation is simple, and easy operating reduces operating trouble and danger.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Among the figure: 1, lower transverse beam; 2, bent leg one; 3, bent leg two; 4, connecting flange; 5, bent leg three; 6, girder contact beam; 7, seat beam; 8, running mechanism; 9, hydraulic jacking system; 10, anchoring mechanism.
The specific embodiment
Embodiment 1: this back supporting mechanism comprises: lower transverse beam 1, girder contact beam 6, seat beam 7, running mechanism 8, hydraulic jacking system 9 and anchoring mechanism 10, two ends at lower transverse beam are connected with bent leg respectively, bent leg is " U " type, between the other end of two bent legs, be connected with girder contact beam, be connected with running mechanism 8, hydraulic jacking system 9 and anchoring mechanism 10 in the bottom of lower transverse beam, the bottom of an end that is connected with lower transverse beam at bent leg is connected with seat beam.
Described bent leg comprises bent leg 1, bent leg 23, connecting flange 4 and bent leg 35, bent leg 1, bent leg 23, connecting flange 4 and bent leg 35 are linked in sequence, constitute " U " type, flange is all arranged in the end of bent leg 1, bent leg 23, connecting flange 4 and bent leg 35.
In Fig. 1, behind the adjustable for height bridge formation machine supporting mechanism by lower transverse beam 1, bent leg 1, bent leg 23, connecting flange 4, bent leg 35, girder contact beam 6, seat beam 7, running mechanism 8, hydraulic jacking system 9, anchoring mechanism 10 is formed.
Connecting flange 4 connects bent leg 23 and bent leg 35, adjust the vertical height of back supporting mechanism by the connecting flange 4 of changing different length, the balance fine setting realizes by hydraulic jacking system, do not need that like this overall structure is made very big adjustment and just can reach the height that changes back supporting mechanism through hole, it is little to change workload.
