Abstract
The utility model provides a hydraulic lifting system, which comprises a frame body. The system is characterized in that hydraulic cylinders are arranged at the two sides of the frame body; the hydraulic cylinders are connected with hydraulic pumps; the hydraulic pumps are connected with hydraulic oil tanks; rocker arms of the hydraulic pumps are connected to the hydraulic pumps through hydraulic connecting rods; and supporting arms are connected with the hydraulic cylinders and arranged at the lower part of the frame body. The system is applied in lifting heavy weight, and has the advantages of small volume, heavy weight, and convenient to carry.
Description
Technical field: the utility model relates to a kind of portable hydraulic lifting system at towing lifting vehicle during vehicle.
Background technology: at present, meet with a street accident or military-designed vehicle is illegal turns out for work and pretend to be in the process of military-designed vehicle at vehicle, need pull vehicle, then need in the process of towing being carried out lifting so that pull by towing vehicle front-wheel or trailing wheel, and existing lifting device can not fold and lifting is convenient inadequately, and existing lifting device fricative heat in the lifting process is very big, influence the service life of device, yet there are no report and whether there is a kind of convenient more perfect mode to solve above problem.
Summary of the invention:
Goal of the invention: the purpose of this utility model is a kind of portable hydraulic lifting system, and problem and the existing lifting device that its purpose is to solve lifting systematic comparison clumsiness in the existing wrecker is inconvenient to dismantle, the folding and inconvenient problem of lift operation.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of hydraulic lifting system comprises support body, it is characterized in that: be provided with hydraulic actuating cylinder in the support body both sides, hydraulic actuating cylinder links to each other with Hydraulic Pump, and Hydraulic Pump links to each other with hydraulic reservoir; The Hydraulic Pump rocking arm is connected to Hydraulic Pump by hydraulic connecting rod; Hold-down arm is connected with hydraulic actuating cylinder, is arranged on the bottom of support body.
The following bottom of hold-down arm is provided with the hold-down arm castor.
The Hydraulic Pump change-over valve is housed on the Hydraulic Pump.
Advantage and effect: the utility model provides a kind of hydraulic lifting device, form by Hydraulic Pump rocking arm, hydraulic connecting rod, Hydraulic Pump change-over valve, Hydraulic Pump, hydraulic reservoir, hydraulic actuating cylinder, support body, support castor, hold-down arm several sections, this device is easy to use, flexible operation, one people just can finish whole operations of lifting process, and various piece can be dismantled, folding, have little, in light weight, the portable characteristics of volume.
Description of drawings:
Fig. 1 is the main structural representation of the utility model;
Fig. 2 is that A of the present utility model is to the local structure scheme drawing;
Fig. 3 is a cooperation towing truck of the present utility model plan structure scheme drawing when using.
The specific embodiment: the utility model is done nearly step explanation below in conjunction with accompanying drawing:
The utility model provides a kind of hydraulic lifting system, and hydraulic lifting system comprises hold-down arm 3, support body 2, hydraulic actuating cylinder 5, hydraulic reservoir 7 and Hydraulic Pump 6; Hydraulic actuating cylinder 5 is arranged on the both sides of support body 2, and hydraulic actuating cylinder 5 links to each other with Hydraulic Pump 6, and Hydraulic Pump 6 links to each other with hydraulic reservoir 7; Hydraulic Pump rocking arm 1 is connected to Hydraulic Pump 6 by hydraulic connecting rod 8; Hydraulic Pump change-over valve 9 is housed, the flexible conversion that act as modulated pressure cylinder 5 of Hydraulic Pump change-over valve 9 on the Hydraulic Pump 6; Hydraulic Pump rocking arm 1 is movable, detouchable, thereby Hydraulic Pump rocking arm 1 can be by the flexible folding and unfolding of controlling hold-down arm 3 of hydraulic connecting rod 8 concrete modulated pressure cylinders 5; Hold-down arm 3 is connected with hydraulic actuating cylinder 5, is arranged on the bottom of support body 2, and with support body 2 for flexibly connecting, hold-down arm 3 can along B shown in Figure 1 to or C to rotation, the fulcrum of its rotation is exactly a hold-down arm 3 and the point of connection of support body 2; The following bottom of hold-down arm 3 is provided with hold-down arm castor 4; The principle of hydraulic actuating cylinder 5 concrete control hold-down arms 3 folding and unfoldings is for when hydraulic actuating cylinder 5 stretches, because hold-down arm 3 links to each other with the two ends of hydraulic actuating cylinder 5, and hold-down arm 3 is flexible connection with support body 2, force hold-down arm 3 along B to inside rotation folding, when hydraulic actuating cylinder 5 shrinks, force hold-down arm 3 along C to decontroling to inner rotary, finish lifting.
Earlier this hydraulic lifting system is placed on by the bottom of lifting vehicle during use, uses Hydraulic Pump rocking arm 1 modulated pressure pump change-over valve 9 then, make hydraulic actuating cylinder 5 be in the desire contraction state; Be connected to hydraulic connecting rod 8 and wigwag motion with Hydraulic Pump rocking arm 1 then, modulated pressure cylinder 5 shrinks, hold-down arm 3 is slowly decontroled to 3 along C, to be propped to specified altitude assignment by the lifting thing, and just can begin the change of wheels tire then or towing truck 10 is inserted support body 2 times, towing truck 10 is linked to each other with support body 2, modulated pressure cylinder 5 stretches then, force hold-down arm 3 along B to folding, make support body 2 carry car body and directly heavy burden dropped on the towing truck 10, begin towing then; After tire to be replaced or towing finish, Hydraulic Pump rocking arm 1 is unloaded from hydraulic connecting rod 8, then it is linked to each other with Hydraulic Pump change-over valve 9, modulated pressure pump change-over valve 9 makes its modulated pressure cylinder 5 be in the desire contraction state, then Hydraulic Pump rocking arm 1 is connected to hydraulic connecting rod 8 and wigwag motion, hydraulic actuating cylinder 5 is shunk, force hold-down arm 3 along C to expansion, make hold-down arm 3 carryings by the heavy burden of towing truck, withdraw from towing truck 10, stretch by Hydraulic Pump rocking arm 1 modulated pressure cylinder 5 then, force hold-down arm 3 slowly along B to folding, and then car body is slowly descended, promptly complete operation takes out this hydraulic lifting system at last and gets final product; In addition, this hydraulic lifting system also is this hydraulic lifting system to be placed on lifted under the thing in the principle aspect the lifting weight, adjusts hold-down arm 3 and stretches out, and holds up and is lifted thing, when treating to put down by the lifting thing hold-down arm 3 is packed up, and puts down to be lifted thing and getting final product.
Below make some performance figure of this device:
Lifting weight: 1 ton;
Operation pressure: 50Mpa;
Defeated oil pump capacity: the 1.3ML of buffering journey;
Usable quantity of fuel: 0.3mL;
The stroke of oil cylinder: 90mm;
The maximum load-carrying capacity of oil cylinder: 5.1TCN;
Oad: long: 883mm is wide: 283mm height: 114mm;
Weight: 12Kg.
