Abstract
The utility model relates to a hydraulic lifting device, which comprises a traction clamping device, the jack of an upper clamping device, an upper clamping device, a main lifting jack, the jack of a lower clamping device, a lower clamping device, a safe clamping device and a component clamping device. The alternative tightness degree of the upper clamping device and the lower clamping device are respectively controlled by the jack of the upper clamping device and the jack of the lower clamping device of hydraulic two oil paths. The load is carried by the main lifting jack to upward move or downward move. The device has small size, safe work, high lifting height and large lifting capacity. The constructional element more than 1000 tons can be lifted after combination and the constructional element more than 350 tons can be lifted to the height of 350 meters. The utility model is particularly suitable for lifting the large constructional element with super volume and super weight.
Description
The utility model relates to a kind of energy with especially big, and overweight member promotes and moves lifting means in place.
Adopting now the integral hoisting mode will especially big or quality be that the above overweight member of kiloton rises to more than 50 meters highly, and up till now for extremely, existing bont all is difficult to accomplish.
It can be that the above overweight member of kiloton rises to height more than 50 meters, safe and reliable hydraulic lifting apparatus with especially big or quality that the utility model aim is to provide a kind of.
The utility model is realized in the following way: be provided with Hydraulic Double oil circuit work clamping device in the main jack of lifting top and the bottom, it is made up of last clamper jack, last clamper, lower gripper jack, lower gripper, last clamper is fixed on and promotes main jack piston top, the last clamper jack that is contained in the clamper top is connected and promotes on the main jack, and last clamper jack piston is connected with last clamper.The lower gripper jack is fixed on promotes main jack bottom, the lower gripper jack piston links to each other with lower gripper on being contained in bracing frame.Pass the clamper jack successively, go up clamper, link to each other with member after promoting main jack, lower gripper jack, lower gripper and member clamper as the steel strand of stressed carrier.The upper and lower clamper jack of the utility model adopts the Hydraulic Double oil circuit, utilize upper and lower clamper jack to control upper and lower clamper respectively and replace degree of tightness, when the clamp holder clamping steel strand are gone up in last clamper jack control, the lower gripper jack unclamps lower gripper, the piston band load that promotes main jack rises or descends, and the lower gripper jack is controlled lower gripper again and clamped steel strand, and last clamper unclamps, promote unloaded rising of main jack piston or decline, it is motionless that member keeps.So going round and beginning again promotes continuously, directly load is raise or drops to preposition.
The equipment that the utlity model has is light, volume is little, easy to operate, characteristics such as use is flexible, hoisting capacity is big, safe and reliable, hoisting depth height.Through probationary certificate: after the utility model combined, can rise to 350 meters height with 350 tons member is reliable and secure; And can promoting matter, to be 1000 tons be the member of 50 * 45 sq ms with upper member or volume.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1---be the utility model structural representation.
Fig. 2---be the utility model scheme of installation.
Referring to accompanying drawing; hydraulic lifting apparatus provided by the utility model is mainly by promoting main jack (4); last clamper jack (2); last clamper (3); lower gripper jack (5); lower gripper (6) and member clamper (8) are formed; more safe and reliable when working in order to guarantee the utility model; between lower gripper (6) and member clamper (8), be provided with safety clamper (7); at jack in case lost efficacy when maybe needing to change jack; be fixed on safety clamper (7) on the bracing frame and clamp steel strand automatically and can prevent effectively that weight from descending, thereby play the safety guard-safeguard effect.For preventing steel strand (9) hoisting type master jack (4) inner chamber of might withdrawing, traction clamper (1) is housed on the bracing frame of last clamper jack (2) top, it can draw the steel strand (9) that stretch out jack gradually automatically.The clamper that the utility model adopted is formed by pressing plate (d), intermediate plate (e), grip block (f), holding screw (a) passes holddown spring (b) pressing plate (d) is fastened on the grip block (f), intermediate plate (e) is installed in the grip block (f), and intermediate plate screw (c) passes pressing plate (d) and is connected with intermediate plate (e).To go up clamper (2) and be fixed on lifting main jack (4) piston head, last clamper jack (2) piston links together by holding screw and pressing plate (d), grip block (f), when last clamper jack (2) piston upwards bounces back, pressing plate (d) upward movement of clamper in the drive (3), intermediate plate this moment (e) unclamps, when piston moved downward, the pressing plate (d) of clamper in the promotion (3) moved downward, and the intermediate plate (e) that is contained in the grip block (f) is clamped.Last clamper jack (2) is connected with the main jack of lifting (4), promotes when promoting main jack (4) piston motion to go up clamper (3), and last clamper jack (2) is along the steel strand upward movement.Lower gripper jack (5) is fixed on bottom, main thousand top (4) of lifting, and lower gripper jack (5) piston connects together by holding screw and pressing plate (d), grip block (f).Steel strand (9) as stressed carrier pass traction clamper (1) successively, go up clamper jack (2), go up clamper (3), hoisting type master jack (4), lower gripper jack (5), lower gripper (6), safety clamper (7), member clamper (8) link to each other with member, during work, it is motionless to promote main jack cylinder, piston reciprocates, because upper and lower clamper jack (2), (5) are the Hydraulic Double oil circuit, the upper and lower clamper of its may command unclamps and clamps.When the clamp holder clamping steel strand are gone up in last clamper jack control, lower gripper unclamps steel strand, promoting main very heavy piston band load rises or descends, clamp steel strand and control lower gripper from the lower gripper jack, last clamper unclamps steel strand again, and main jack piston is unloaded to rise or descend, it is motionless that weight keeps, go round and begin again, upper and lower clamper replaces degree of tightness, until load being raise or dropping to predetermined height.
