Abstract
The invention relates to a novel method of an inversion construction process of a fixed top cylindrical vertical type storage tank, belongs to the technical field of petroleum storage, and aims to solve the problem that a lifting column cannot be mounted inside the fixed top cylindrical vertical type storage tank after a tank bottom plate, a top wall plate and a tank top are assembled in the inversion construction of the fixed top cylindrical vertical type storage tank. The technical key points of the novel method are as follows: the height of the lifting column before being mounted is less than that of the top wall plate, so that the lifting column can be mounted in place inside the tank body at a time, and meanwhile a balance column is mounted in the center of the storage tank; the lifting column is connected with the balance column through a pull rod, and an adjusting bolt is adopted to adjust the stress of the pull rod, so that the lifting column and the balance column can be lifted up smoothly. The lifting column and the balance column both consist of sleeves and inner cores and the inner cores are connected with a hydraulic oil system, so as to enable hydraulic oil to enter the sleeves, so that the sleeves and the wall of the tank are lifted upwards for a certain distance. At the moment, the lifting column and the balance column can be re-fixed, and then the wall of the tank can be lifted by an electric chain block independently.
Description
Technical field
The invention belongs to oil storage technical field, relate to the new mode of a kind of large-scale fixing top vertical cylinder storage tank inverted construction technique.
Background technology
Along with the fast development of China's economic construction and improving constantly of living standards of the people, China's oil consumption increases year by year. according to statistics, China's oil year in 2012, consumption reached about 500,000,000 tons. therefore, all parts of the country are being built and are building a large amount of crude oil banks and finished oil bank by continuing. and petrol storage tank is the dedicated storage equipment of crude oil and finished oil, the key link during oil storage is built. at present, the petroleum storage tank that China builds is based on field oil-tank, and in the majority with vertical and cylindrical metal structure.
The vertical and cylindrical metal storage tank of store product oil, its tank deck is generally fixing along structure. for the tank skin of this type of storage tank in construction, because flip-clip has following advantage:
1). Ground Operation, therefore construct comparatively safe, greatly reduce accident rate;
2). owing to not needing large-scale lifting appliance, can construction costs be reduced;
3). operating efficiency is high, can shorten the construction period;
4). be convenient to control construction quality.
So the construction of domestic large-scale fixed roof tank adopts the method more. and in inverted construction method, because motor-driven chain hoist multi-point lifting upside-down construction technique is simple, construction safety is reliable, being widely adopted in practice of construction. the construction technology of this kind of method is: the tank bottom of storage tank, in tank, lifting column and motor-driven chain hoist are evenly set around tank skin after top layer wallboard and tank deck construction, center mast is set at storage tank center simultaneously, inside tank skin, lower edge arranges packing, be fixed on tank skin with sight rail and jack swelling, lifting column and center mast are connected on top to strain lifting column, in tank, arrange control housing be used for controlling motor-driven chain hoist, maneuvering and control cabinet makes motor-driven chain hoist start simultaneously, promote packing, tank body is made slowly to increase, thus realize the order assembling of tank shell.
But this kind of method in practice of construction process because lifting column height must exceed the height of top layer wallboard, just top layer wallboard can be promoted to preposition, therefore, after tank deck and top layer wallboard are installed, lifting column cannot be erected in tank. two kinds of solutions that in practice of construction, general employing is following at present:
1). the basic ring beam outside tank arranges lifting column, promotes top layer wallboard and tank deck from outside. this kind of method needs to install a lifting column outside tank, makes construction become complicated, has often prolonged the construction period; In addition for the foundation not having ring beam, this kind of more difficult realization of construction method.
2). when tank deck is constructed, according to the desired location of lifting column, first reserve polylith top board wouldn't assemble, make to be arranged in the lifting column of border in tank and pass tank deck, treat top layer wallboard rise to desired location and with second layer wallboard assembly welding after, again these tank deck plates to be carried out assembling and welding. the problem that this kind of construction method is brought is: the tank deck plate mending dress reserved needs aloft work, adds difficulty of construction, the danger of construction is increased; This time promote tank body in addition, lifting column cannot be connected with center mast, only fixes lifting column by diagonal ligament, and during lifting tank body, its stressing conditions is poor.
Patent of the present invention is just in the tank skin work progress of fixed roof tank, top layer wallboard and tank deck construct after the problem arranged in tank existing for lifting column propose. lifting once mounting in tank of shutting out both can have been made in place, reserved top board can have been avoided again and the problem of the aloft work brought.
For oil storage, large-scale oil storage tank that is several, tens even more same warship lattice generally will be built in reservoir area, now adopting the method in patent of the present invention to install lifting column will make construction become simpler, convenient, greatly can improve operating efficiency, reduce construction cost, the economic benefit of enterprise.
Summary of the invention
The hydraulic lifting lifting column structure that the motor-driven chain hoist multi-point lifting flip-clip that the present invention relates to uses is as shown in Figure 1. and lifting column is primarily of 6---inner core, 7---sleeve, 8---pipe nipple composition.4---seal ring, it plays the sealing function between inner core 6 and sleeve 7. before lifting column is installed, 1---base plate has been laid complete, the assembling of order 9---top layer wallboard and 10---tank deck completes. in appropriate location, top layer wallboard lower end, 2---packing and 3---hanger are set, by 5---jack, wallboard is connected with lifting column. balance columns is as shown in the figure set at tank body center, be connected by the 12---cylinder lever connecting rod be horizontal between lifting column with balance columns, 13---is set at the midway location of cylinder lever connecting rod and adjusts bolt. paste strain sensing chip in the appropriate location of cylinder lever connecting rod 12 after to be installed, now regulate adjustment bolt 13, when making the pulling force of cylinder lever connecting rod 12 and jack 5 mention wallboard, the side direction capsizing moment that lifting column produces is balanced each other, slide axially to ensure can produce freely between inner core 6 and sleeve 7, jammed phenomenon is avoided to occur. in order to cylinder lever connecting rod 12 being made to remain level in lifting column rise process, balance Du has been designed to the structure (as figure) identical with lifting column. and lifting column is circumferential in being evenly arranged along tank skin in tank, as shown in Figure 2, each lifting column is connected with balance columns by cylinder lever connecting rod 12, so after regulating adjustment bolt 13, balance columns radial direction does not stress, also ensure that the smooth and easy rise of balance columns axis.
Lifting column and balance columns lean on the pressure of hydraulic oil upwards to rise. and its fuel-feed system is as shown in Figure 3. by hydraulic oil pump to fuel ring pipe fuel feeding, the oil inlet port of each lifting column (comprising the balance columns at center) bottom inner core is connected with fuel ring pipe by pipeline. and valve is equipped with in the entrance entering oil pipe line at each lifting column, regulate the valve at each lifting column oil inlet port place, it is made to open path identical, equal to ensure the flow of the hydraulic oil entered in lifting column sleeve 7, thus each lifting column can be made upwards to rise with identical speed. adjust regulating the valves of balance columns oil circuit entrance simultaneously, the upwards lifting speeds of balance columns is made to keep synchronous with the ascending velocity of surrounding lifting column.
