The driving device comprises a crankshaft and crank link mechanism connected with a plurality of hydraulic oil cylinders, and is characterized in the an input shaft is arranged at each of the left end and the right end of the crankshaft and crank link mechanism, and the input shafts are connected with a power source device respectively. Compared with the prior art, whole balance, stability, and stress passing characteristic of the driving device are improved greatly, and the device is more convenient and economical to manufacture and suitable for the work condition of the long-term stable operation required during production operation of an industrial and mining enterprise.

Description

The drive unit of a kind of bent axle, crank hydraulic jack
Technical field
The utility model belongs to bent axle, crank hydraulic jack, is specifically related to the drive unit of a kind of bent axle, crank hydraulic jack.
Background technique
Traditional bent axle, the drive unit of crank hydraulic jack are one-sided driving, as shown in Figure 1, 2, the power source being made up of motor 6, speed reducer 5 is connected through coupling 4 and the single-ended input shaft 3 of bent axle (handle) linkage mechanism 2, driving crank (handle) linkage mechanism 2 rotates, bent axle (handle) 201 of bent axle (handle) linkage mechanism 2 will be rotatablely moved and be changed into linear reciprocating motion by connecting rod 202 and slide block 203, and pushed horizontal hydraulic jack 1 is realized linear reciprocating motion.
There is bent axle (handle) laod unbalance, inclined to one side lotus, unbalance loading problem in this one-sided driving drive unit, is generally applicable to below three-crankshaft (handle).Along with industry equipment maximizes, the quantity of hydraulic jack increases (as 5 or more), bent axle thrust increases simultaneously, when the moment of torsion of input shaft strengthens, be bent axle turn number be increased to 5 or more and every bent axle turn power transmission strengthen time, it is load unbalanced, lotus partially, unbalance loading is more serious, input shaft and crank throw torsional deformation problem are more obvious, force-transfer characteristic worsens, can cause the balance of bent axle (handle) mechanism, bad stability, the unfavorable situations such as vibrations increasing and noise rising, unfavorable to installing operation steady in a long-term, bent axle turns footpath simultaneously, input shaft diameter of axle size strengthens, difficulty of processing is large, less economical.
Model utility content
The purpose of this utility model is to provide the drive unit of a kind of bent axle, crank hydraulic jack, there is serious lotus partially in solution prior art, be not suitable with the problem that turns the next one-sided high pulling torque distortion of several multi-bands because of bent axle, crank, thereby significantly improve balance, stability, the force-transfer characteristic of drive unit operation, make its operation steady in a long-term.
The technological scheme that realizes the employing of the utility model object is as follows:
The bent axle that the utility model provides, the drive unit of crank hydraulic jack, comprise the bent axle, the connecting rod that are connected with some hydraulic jacks, input shaft is all established at the two ends, left and right of described bent axle, connecting rod, and described input shaft connects respectively power source.
The speed reducer that described power source comprises motor, is connected with motor, described speed reducer is connected with the input shaft of described bent axle, connecting rod by coupling.
Described hydraulic jack is identical with the quantity of bent axle, crank-connecting rod.
The beneficial effects of the utility model are, having realized left and right sides while driving crank (handle) linkage mechanism rotatablely moves, total torque balance is given to the input shaft at two ends, the moment of torsion that two ends input shaft and side bent axle are turned reduces by half and point balancing, when bent axle hydraulic jack quantity increases, or thrust strengthen time, with respect to one-sided driving drive unit, the balance of the utility model drive unit entirety, stability, force-transfer characteristic has obtained very large improvement, manufacture is more convenient, economical, be suitable for the operating mode of desired operation steady in a long-term in industrial and mining enterprise's production run.
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is the plan view of existing bent axle hydraulic jack drive unit.
Fig. 2 is the sectional drawing of existing bent axle hydraulic jack drive unit.
Fig. 3 is structural representation of the present utility model.
Embodiment
See Fig. 3, the bent axle that the utility model provides, the drive unit of crank hydraulic jack, comprise bent axle (handle) linkage mechanism 2 being connected with some hydraulic jacks 1, input shaft 3 is all established at the two ends, left and right of described bent axle (handle) linkage mechanism 2, and described input shaft 3 connects respectively power source; The speed reducer 5 that described power source comprises motor 6, is connected with motor 6, described speed reducer 5 is connected with the input shaft 3 of described bent axle (handle) linkage mechanism 2 by coupling 4.
Hydraulic jack is five (or more than five), and each hydraulic jack operating pressure is 16MPa, cylinder diameter 170mm, and stroke is 200mm; Bent axle (handle) linkage mechanism 2 corresponding employing five bent axles (handle) linkage mechanisms, each thrust turning is 360KN, stroke 200mm; In the time that five bent axles (handle) turn round, each change of team occurs that three turn the operating mode of work done simultaneously, and each turns the thrust that has a maximum 3x360KN=1080KN, and the maximum required input moment of torsion of five bent axles (handle) is 67500N.m.
If adopt traditional one-sided driving drive unit, need to configure Medium-voltage motor (660v) more than 450KW, the input torque of one-sided input shaft is 67500N.m, more than shaft diameter is greater than 340mm, and so high moment of torsion of the single-ended input of crank throw, the other end works without input torque the crank throw effect of supporting, unbalance loading is serious, simultaneously because of five crank throws, crankshaft length increases obviously, transmission length, distance increases, uneven, swing more obvious, Efficiency Decreasing, in the design of mechanical structure, very large difficulty is brought in stress distribution aspect, in long-time running because of unbalance loading, high pulling torque and the axle that produces turns distortion, uneven, swing, the vibrations that cause, noise is difficult to overcome, therefore difficulty of processing is large, reliability, stability, less economical, the operating mode that will realize long-term continuous and steady operation in actual production has problem, be difficult to apply.
The utility model is because being left and right both-end driving crank (handle) linkage mechanism simultaneously, two groups of 220KW pressure common motors are adopted, garden post hard-tooth surface speed reducer, through the two ends, left and right of snake type spring coupling and five crankshaft & connectings, input shaft is connected, drive five crankshaft & connectings to rotate with 60 revs/min of speed simultaneously, and the direction of rotation is identical, five crankshaft & connectings change rotatablely moving of bent axle the to-and-fro motion of connecting rod with 60 beats/min of frequencys into, thereby drive five horizontal hydraulic oil cylinders that are connected with the connecting rod of crank mechanism to realize the Double-action reciprocating motion of 60 beats/min.The moment of torsion of each input shaft is 33750N.m, shaft diameter is 230mm, be significantly smaller than one-sided driving, significantly improve input shaft and side bent axle turns unbalance loading problem, power transmission efficiency improves, more balance of stressed symmetry, simultaneously all balanced configuration easily, layouts of power source (motor, speed reducer, coupling), therefore balance, stability, the reliability of device operation significantly improve, and implement to have Economy.
