Abstract
The utility model discloses a cantilever crane structure of a highway bridge erecting machine. The cantilever crane structure comprises a front bracket cross beam mechanism, a hydraulic jacking mechanism, a cart traveling mechanism, a machine support mechanism and a hydraulic pump station, wherein the front bracket cross beam mechanism comprises a saddle type cross beam and a truss type guide beam for a hoist trolley to move transversely while lifting heavy articles; the hydraulic jacking mechanism comprises two sets of hydraulic lift cylinders; the hydraulic lift cylinders are externally connected to the hydraulic pump station; and the machine support mechanism comprises inner extensible sleeves and outer sleeves, and the inner extensible sleeves are in a slide fit with the outer sleeves. The cantilever crane structure of the highway bridge erecting machine can provide a simple and practical cantilever hoisting manner in case of special conditions under the premise of ensuring the normal functions of a highway or railway bridge erecting machine.
Description
Technical field
The utility model relates to highway bridging machine special operation condition operation of (as the place ahead rivers, bridge, high-tension line) under special operation condition restriction, can under the prerequisite of the very little variation of former road bridge machine, realize lifting, the installation exercise demand of the place ahead weight, not change the performance of former bridge formation machine simultaneously.
Background technology
Present stage is along with the development of infrastructure constructions such as highway in China, domesticly emerged multiple class, the highway bridging machine of many types of formula, setting up field working conditions simultaneously also varies, but domestic existing type is at fore-stock, finish the lifting of weight between the after-poppet, operation in place, for this reason for ease of the lifting of the cantilever under extraordinary situation task, design this kind mechanism, to satisfy the place ahead cantilever operation, as power station, the place ahead, gate etc., and below underwater work, the template of transporting on the road, pile templates etc. all can adopt this kind structure to set a roof beam in place, the cantilever lifting operation.This kind mechanism has promptly saved the supporting device category of unit in charge of construction, has also reduced equipment place occupancy, is a kind of novel type.
The utility model content
The cantilever that the purpose of this utility model provides a kind of highway bridging machine hangs structure, can provide a kind of simple, practical cantilever lifting mode under the condition that satisfy public railway bridge erecting machine normal function during at special operation condition.
In order to achieve the above object, the technical solution adopted in the utility model is:
The cantilever of highway bridging machine hangs structure, comprise fore-stock crossbeam mechanism, hydraulic lifting mechanism, cart walking mechanism, mechanical support mechanism, hydraulic power unit, the truss-like nose girder that described fore-stock crossbeam mechanism includes the saddle shaped crossbeam and laterally moves for the trolley lift heavy, described hydraulic lifting mechanism includes two cover hydraulic lifting oil cylinders, the hydraulic lifting oil cylinder is connected to hydraulic power unit outward, described mechanical support mechanism includes the interior telescopic that is slidingly matched mutually, overcoat, interior telescopic is fixedlyed connected with the hydraulic lifting oil cylinder of its top, and overcoat is connected with the cart walking mechanism of its below.
Saddle shaped crossbeam of the present utility model and truss-like nose girder and nose girder top trolley system form the part of this cantilever hoisting structure jointly.Cantilever construction mainly consists of: crossbeam, hoist cylinder, mechanical-stretching supporting leg, protection bearing pin, adjustment be joint, bottom traveling mechanism of the larger traveller highly; described trolley is the vertical shift walking on nose girder; described dolly and lifted weight together stride across the saddle shaped front beam; weight is delivered to the place ahead assigned address, finish cantilever lifting job process.Simultaneously horizontal if desired when mobile, among a small circle in, can make dolly and laterally move, can start preceding, medium-height trestle cart on a large scale when mobile, realize the laterally mobile of complete machine and weight.
Critical piece of the present utility model all adopts former bridge formation machine component, has only the fore-stock beam shape to change slightly, and the girder transition segment redesigns according to semi girder is stressed owing to the lift heavy reason.The recessed portion size designs according to the lifted weight shape in the fore-stock crossbeam horse-saddle.
The utility model has the advantages that on the basis of satisfying the normal function of use of general bridge formation machine, increased the lifting operation function of the place ahead cantilever end, it is simple that this scheme has manufacturing simultaneously, advantage such as easy to operate, be adapted to the lifting operation of extraordinary occasion, slightly adjusting on the basis that does not influence former bridge formation machine performance and can realize this function, is a kind of a tractor serves several purposes, novel structure.
Description of drawings
Fig. 1 carries out cantilever lifting operation front view for weight of the present utility model by fore-stock;
Fig. 2 is a fore-stock crossbeam structural scheme of mechanism of the present utility model.
The specific embodiment
Referring to accompanying drawing, the cantilever of highway bridging machine hangs structure, include fore-stock crossbeam mechanism 1, can adjust telescopic oil cylinder 2 is installed in the fore-stock crossbeam mechanism 1, interior telescopic 3 connects with the oil cylinder flange, interior telescopic 3 slides in overcoat 4, and this telescoping mechanism is mainly adjusted the main beam level height difference, prevents that the longitudinal gradient discrepancy in elevation is excessive and causes the dolly slippage.Interior telescopic 3 bottoms connect with traversing trolley assembly 5 flanges; Trolley 6, weight 7 vertically move on the bridge formation machine, by the fore-stock crossbeam, transport in the place ahead cantilever end assigned address, finish the cantilever lifting, can pass through bottom cart, top dolly transverse movement during as the need sideways transfer, realize the sideways transfer function of complete machine weight.
Claims (1)
