Description
Technical field
The utility model relates to a kind of large-scale storage tank construction equipment, relates to the derusting by sandblasting of a kind of storage tank outer wall, japanning insulation, anticorrosion and the hoist that is used for the storage tank external wall construction that annex is installed specifically.
Background technology
In the large-scale storage tank construction, the derusting by sandblasting of storage tank outer wall, japanning insulation, mode anticorrosion and that annex is installed mainly adopt crawler belt hanging or scaffold formula operating type at present, and wherein the scaffold formula can be divided into suspension type and pulley type again.Experience and lessons in the past prove no matter adopt above any way, all exist following deficiency:
A, activity duration are long.When adopting the operation of crawler belt hanging, be subjected to its restricted number, generally once can only carry out a group job, cause long in time limit; When adopting the operation of scaffold formula, scaffold is prefabricated and the set-up time is long.
B, poor stability (security incident occurs repeatedly).When adopting the operation of crawler belt hanging, there is wire rope problem out of control in the work, do not meet safety requirements; When adopting the operation of scaffold formula, owing to be difficult to reach the regulation technical requirements, instability, operating personnel's difficulty in place is prone to personnel casualty accidents.
C, construction cost height.When adopting the operation of crawler belt hanging, a 50T crawler crane machine-team every day costliness; When adopting the operation of scaffold formula, rolled steel dosage is big, and is prefabricated big with installation workload, and primary structure is difficult to reuse.
D, backward in technique.Two kinds of schemes are in the hand labour stage from technical standpoint.Incompatible with the storage tank due technical level of constructing.
By above situation as can be seen, large-scale storage tank external wall construction facility fall behind, and have had a strong impact on the progress and the quality of storage tank construction, are badly in need of the development of special tool.
Summary of the invention
The utility model provides a kind of optional position that makes job platform arrive tank skin steadily, accurately at above-mentioned existing in prior technology weak point just, and can firmly be positioned the hoist that is used for the storage tank external wall construction that certain a bit carries out operation.
The purpose of this utility model can realize by following measure:
The hoist that is used for the storage tank external wall construction of the present utility model comprises travelling car and is lifted on the job platform of travelling car below by hoisting mechanism; Described travelling car comprises vehicle frame, is installed in hoisting mechanism and walking mechanism on the vehicle frame upper frame; Described hoisting mechanism is made up of left and right two winding drums that are provided with in the coaxial line mode that same set of power set drive, and the lower end of the steel cable that is drawn by left and right two winding drums combines with the both sides frame of job platform framework respectively; Described walking mechanism is formed by power set with by the wheel mechanism of walking that power set drive, and this walks the below that wheel mechanism is arranged on the vehicle frame upper frame, and travelling car is placed on the storage tank outer wall stiffening ring by walking wheel mechanism.
Power set described in the utility model are to be made of direct current generator and worm type of reduction gearing.
Can on storage tank outer wall stiffening ring, make displacement movement more steadily, reliably for guaranteeing travelling car around storage tank, the utility model is provided with the directive wheel that matches with the edge-on limit of storage tank outer wall stiffening ring below the vehicle frame upper frame that is positioned at the travelling wheel mechanism outside, installed inside has the support wheel that matches with the storage tank outer wall on the base of vehicle frame.
A bit carry out operation for making job platform can firmly be positioned certain, the utility model is equipped with two support bars that match with the storage tank outer wall on the inboard frame of job platform, and this support bar is length-adjustable flexible rod-type magnetic force supporting rod.
For further increasing operating personnel's safety, left and right two anti-inclination safety locks are installed on job platform, two safe wire rope that pass from safety lock are separately fixed on the travelling car.
Operating principle of the present utility model is as follows: travelling car is loaded on the tank wall stiffening ring by four travelling wheels, drive a direct current generator as power source by battery, drive away wheel mechanism by turbine and worm reducer and linked transmission, and then the drive travelling car moves along the tank skin hoop.The another set of power set of being made up of direct current generator and reducer are housed on the travelling car, driving winding drum by gear transmission mode rotates, job platform moves up and down by wire rope on the winding drum, by this two covers transmission system, job platform can move on to arbitrary operating position of tank wall very easily.
The support bar that is provided with on the job platform is the threaded-insert type structure, can regulate the length of support bar by rotation mode, is used to adjust the distance of job platform and tank skin, and the strut front end is equipped with electromagnet, and job platform is attached on the tank skin very quietly.For guaranteeing job safety, the anti-inclination safety lock of two covers is housed on every cover electric lift, it is a kind of independently mechanical device, when fracture or job platform take place and tilt to limit definite value in load cable, safety lock can pin safe wire rope automatically in setting lock rope angle (for example 4 °), has so just effectively prevented the job platform falling accident that the wire rope accident has caused when rupturing.Action button is housed on the job platform, and during work, the operating personnel only needs the control button on the manoeuvring platform, can finish the walking of travelling car and the lifting of job platform.By the use of magnet arrangement and anti-inclination safety lock, can effectively ensure stable, the safety of job platform.
The utility model compared with prior art has following beneficial effect:
1) safety aspect: 1. adopt battery as power supply, avoided dependence, do not have high pressure, safety to normal electricity; 2. support bar the stability that has guaranteed platform is set, also ensured constructor's safety simultaneously; 3. adopt worm type of reduction gearing, avoided falling of platform, protected worker's safety with auto-lock function; 4. on job platform, installed anti-inclination safety lock additional, when run-off the straight of operation platform or load cable generation fracture, safety lock can pin safe wire rope automatically in setting lock rope angle (for example 4 °), can avoid because the generation of wire cable rupture or the disabled high-altitude falling accident that causes;
2) operating personnel can work independently, and handle simply, no longer need the assistance of auxiliary work post;
3) be the flexible surface structure with the contacted travelling wheel of tank skin, directive wheel, support wheel, can effectively avoid the destruction of wallboard anticorrosive coat.
In sum, the release of the utility model hoist is not only for carry out work such as the derusting by sandblasting of storage tank outer wall, japanning insulation, winding staircase, foamite system, sanding apparatus, the wind girder condition that facilitates safe, reliable, efficiently, and this hoist also has scientific and reasonable for structure, away from high voltage source, save manually economical and practical advantage.
