Abstract

The utility model relates to a prestress tensioning trolley, belonging to the technical field of the bridging. The prestress tensioning trolley is characterized in that four steel skeletons form a trolley vertical support, the tops of the steel skeletons are provided with a block, the middle of the trolley vertical support is provided with a tensioning work table, the bottom of the trolley vertical support is provided with a winch, the tensioning work table is matched with the trolley vertical stand through a fixed pulley in an up-and-down sliding way, and the outer sides of the steel skeletons are provided with energy-absorbing plates. The prestress tensioning trolley has the benefits that the project cost is greatly saved, the construction is quickened, simultaneously, the inconvenience of the prestress tensioning jack is improved, the connection is simple, the operation is simple, the construction is convenient, and the control is easier during the construction.

Description

A kind of prestressed stretch-draw chassis
Technical field
The utility model belongs to the bridging technical field.
Background technology
When bridging, consider that the pipeline prestressed stretch-draw is to the stressed importance of beam body, weight owing to jack in stretching process weighs more than the 280KG, artificially can't handle, install by present artificial or non-special-purpose machinery, damage of components easily takes place in the installation process, phenomenon such as stripped thread, fracture of wire takes place sometimes and the casualties that produces in the stretching process.Simultaneously, waste of manpower, efficient is not high.
Summary of the invention
The purpose of this utility model is: a kind of prestressed stretch-draw chassis is provided, it can to stretch-draw with jack carry out fast, effectively connection.
The technical solution of the utility model is: constitute the chassis stand by four steel frames, at the steel frame top hoist is installed, at chassis stand middle part the stretch-draw workbench is installed, in chassis stand bottom hoist engine is installed, the stretch-draw workbench slides up and down with the chassis stand by fixed pulley and cooperates, and in the steel frame outside energy-absorbing plate is installed.
The beneficial effects of the utility model are: saved engineering cost greatly, when having accelerated construction, improved the inconvenience that the prestressed stretch-draw jack is installed, connected simply, handled easily is convenient to construction, makes the easier control of work progress.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model lateral view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, hoist, the 2nd, rain-proof shelter, the 3rd, angle steel and round steel skeleton, the 4th, stretch-draw workbench, the 5th, energy-absorbing plate, the 6th, fixed pulley, the 7th, road wheel, the 8th, hoist engine.
Road wheel 6 mainly makes things convenient for chassis to carry moving in the stretching process, hoist 1 and hoist engine 8 are chief components of chassis, cooperate the front and back of fixed pulleys 6 control stretch-draw jack and move up and down by hoist 1 and hoist engine 8, energy-absorbing plate 5 and rain-proof shelter 2 main protectors, steel strand fracture of wire produce power absorbed when energy-absorbing plate 5 was mainly used in jack tension, angle steel and round steel skeleton 3 mainly are the load-carrying members of chassis, mainly bear and be used to hang hoist 1 and hoist engine 8 and fixed pulley 6, set up workbench 4, workbench 4 provides interim operating platform for construction.
Its course of work is:
Carry out steel strand tension work with the stretch-draw chassis after preparation of construction is finished, concrete steps are as follows:
A. clear up the mortar of backing plate and steel strand surface;
B., ground tackle is installed, intermediate plate;
C. by hoist and hoist engine that jack is in place, the instrument anchor hole position on the jack is arranged with the position, hole of component ends work anchor and is wanted consistent;
E. the moveable anchor intermediate plate is urgent, and intermediate plate is evenly urgent and expose unanimity;
F. oil pump feed is given the jack tension oil cylinder, and checks the deviation of stretch value and calculated value at any time.
G. stretch-draw is held lotus and is reviewed stretch value behind the regulation oil pressure, and anchoring is implemented in qualified back;
H. jack piston backhaul;
I. remove jack;
J. excise unnecessary steel strand.
