Abstract
The invention relates to the field of installation and construction of large-scale mechanical equipment, in particular to a hydraulic lifting method for large-scale equipment which lifts the equipment to required installing position height by continuously increasing lifting bases of the equipment in the construction operation for lifting the equipment by utilizing hydraulic jacks. The hydraulic lifting method comprises the following steps of: installing the lifting base of the equipment and the jack, protectively dismantling a temporary supporting base in the equipment after utilizing the jack for jacking the equipment up to a certain height, installing an exchange base for lifting the equipment, and descending the jack to complete the first-time lifting of the equipment; increasing the base of the jack, jacking the equipment up to a certain height, increasing the exchange base of the equipment, and descending the jack to complete the second-time lifting of the equipment; and continuously increasing the base of the jack and the exchange base of the equipment to lead the equipment to reach the required installing height. The hydraulic lifting method is simple, and easy to master, has wide operation range, short construction period, fewer used mechanical equipments, no working aloft and high safe reliability, and is applicable to the lifting construction operation of various large-scale equipments.
Description
Technical field:
The present invention relates to heavy mechanical equipment installation field, particularly utilizing hydraulic jack to carry out in the construction operation of equipment jacking, by continuous increase equipment jacking base, with the hydraulic lifting method for large-scale equipment of equipment lifting to required installation site height.
Background technology:
In the mechanical equipment installation work, the legacy equipment installation method is equipment is moved to that the installation site is installed after from the assembling position jacking to certain altitude or directly with crane equipment to be hung the installation site and install.When needing the very high height of jacking for main equipment installation, especially equipment in some enclosure spaces, traditional equipment installation method program is loaded down with trivial details, the required human and material resources of constructing are restricted, the jacking difficulty of equipment is big, and efficient and safe reliability are low, have a strong impact on construction speed.
Summary of the invention:
The objective of the invention is deficiency, a kind of jacking method that is more suitable for equipment jack-up construction job requirements is provided at existing installation jacking technology.Need not large-scale crane, large-scale driving in the method in the jacking operation process of equipment, no aloft work uses mechanical equipment few, and safety of operation is reliable, level of mechanization when having improved the equipment jacking and equipment jack-up construction efficient.
Realize the foregoing invention purpose by the following technical solutions: a kind of hydraulic lifting method for large-scale equipment, undertaken by following step:
(1) makes the exchange base: the intensity of calculating the exchange base according to the weight of Lifting Equipment, the top lifting height required according to equipment, determine the quantity and the height of exchange base, the welding production quality of exchange base should meet " code for acceptance of construction quality of steel structures " requirement;
(2) jack base of erecting equipment jacking and jack start jack, and protectiveness behind the equipment jack-up certain altitude is removed the interim base for supporting of equipment, and the exchange base of erecting equipment jacking falls jack then after rise simultaneously, finishes the jacking first time of equipment;
(3) increase the exchange base in the jack base bottom, improve the jack height, start jack,, increase the exchange base of equipment, fall jack after rise, finish the jacking second time of equipment equipment jack-up certain altitude;
(4) repeating step (3) constantly increases the exchange base to improve the jack height in the jack base bottom, increase the exchange base quantity of equipment simultaneously, makes equipment reach required setting height(from bottom).
Owing to adopt technique scheme, compared with prior art, the invention has the beneficial effects as follows:
1. method is simple, grasp easily, and the operation face width, the duration is short.
2. use mechanical equipment few, major equipment is four large-tonnage hydraulic jacks of same specification, and the operation control of such hydraulic jack is simple, not fragile, convenient and reliable.
3. do not need large-scale crane, no aloft work helps safe in operation (operating personal is fixed-point operation on the assembly platform of equipment all the time).
4. can not produce the jacking distortion of equipment, the jacking quality is good.
5. all operation is fluid control, and comformability is strong, not limited by environmental conditions.

Among the figure: Lifting Equipment 1; Hydraulic jack 2; Jacking base 3; No. 1 exchange base 4; No. 2 exchange bases 5; No. 3 exchange bases 6; No. 4 exchange bases 7; Interim support carriers 8; No. 5 exchange bases 9.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Referring to Fig. 1, Fig. 2, concrete operations step of the present invention is:
(1) making of exchange base: the exchange base belongs to the steel structure weldment, and its making should meet " code for acceptance of construction quality of steel structures ", the short weld seam of weldering earlier during welding, the long weld seam of weldering again, the therefrom mind-set external welding of long weld seam.After welding finishes, check the parallelism of two end faces up and down, according to design paper processing tie bolt hole.Have the exchange base of five kinds of models in the present embodiment, i.e. 7, No. 5 exchanges of No. 1 exchange base 4, No. 2 exchanges base 5, No. 3 exchanges base, 6, No. 4 exchanges base base 9.
(2) erecting equipment jacking base 3 and hydraulic jack 2: remove the foreign material of Equipment Foundations, jacking base 3 and hydraulic jack 2 are installed, the jacking first time of preparation machine, as shown in Figure 3.
(4) hydraulic jack 2 jackings, the interim support carriers 8 of dismounting equipment: open the fluid control pumping plant of hydraulic jack 2, with equipment jack-up certain altitude; Protectiveness is removed the interim support carriers 8 of equipment, and the exchange base is installed, and returns and falls hydraulic jack 2, finishes the jacking first time of equipment, as Fig. 4, Fig. 5, shown in Figure 6.
(3) jacking for the second time: increase the base of hydraulic jack 2, equipment is continued the jack-up certain altitude, increase the devices exchange base, fall hydraulic jack 2 then after rise, remove the jacking base, finish the jacking second time of equipment, as Fig. 7, Fig. 8, shown in Figure 9.
(4) constantly increase the jacking base of hydraulic jack 2 and the exchange base of equipment, needed position height is arrived in the equipment jacking, as Figure 10, Figure 11, shown in Figure 12.
