The utility model content
The utility model overcomes the deficiency of prior art, and technical matters to be solved provides a kind of safety emulsification fluid cylinder crane running gear good and simple in structure, realizes the long continuously distance walking of crane under the coal mine.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of emulsification fluid cylinder crane running gear; Comprise first lifting hydraulic cylinder, second lifting hydraulic cylinder, advance and retreat hydraulic actuating cylinder, frame, gear, first base and second base; First lifting hydraulic cylinder is fixed on first base, on the piston rod of said first lifting hydraulic cylinder lifting support is installed; One end of the frame that profile is rectangular is provided with sliding bar, and an end of said sliding bar is sleeved on the lifting support, and the upper and lower of frame is respectively equipped with parallel relative first tooth bar and second tooth bar, and the other end of frame links to each other with the piston rod of advance and retreat hydraulic actuating cylinder; The advance and retreat hydraulic actuating cylinder is hinged on the hoist cylinder seat; The hoist cylinder seat links to each other with the piston rod of second lifting hydraulic cylinder; Said second lifting hydraulic cylinder is fixed on second base and is parallel with first lifting hydraulic cylinder, and gear is fixed on the cantilever axletree and between first tooth bar and second tooth bar.
The beneficial effect that the utility model compared with prior art has is: a kind of upper and lower of emulsification fluid cylinder crane running gear upper spider is respectively equipped with parallel relative first tooth bar and second tooth bar; Frame is under the control of first lifting hydraulic cylinder and second lifting hydraulic cylinder; Realize up-and-down movement, make the gear and first tooth bar mesh, perhaps mesh with second tooth bar; The sense of motion of advance and retreat hydraulic actuating cylinder control frame; The gear that makes rack drives be engaged with is realized rotating, and gear is fixed on the cantilever axletree, and the rotation of gear drives the crane roller of installing on the cantilever axletree and rotates; The rotation of crane roller has driven the walking of crane; First lifting hydraulic cylinder, second lifting hydraulic cylinder and advance and retreat hydraulic actuating cylinder adopt all that existing emulsion pressure system is a power under the mine, have simplified the hydraulic efficiency pressure system of crane walking, the safety that has improved the crane running gear.
The utility model can improve the equipment durability effectively through the pressure of input emulsion and the adjustment of flow are changed kinematic velocity, prolongs the service life of equipment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of a kind of emulsification fluid cylinder of the utility model crane running gear.
Among the figure: 1 for lifting support, 2 for sliding bar, 3 be first lifting hydraulic cylinder, 4 be first base, 5 be first tooth bar, 6 for the cantilever axletree, 7 for gear, 8 for frame, 9 for advance and retreat hydraulic actuating cylinder, 10 for hoist cylinder seat, 11 be that second lifting hydraulic cylinder, 12 is that second base, 13 is second tooth bar.
The specific embodiment
Like Fig. 1; A kind of emulsification fluid cylinder crane running gear; Comprise first lifting hydraulic cylinder 3, second lifting hydraulic cylinder 11, advance and retreat hydraulic actuating cylinder 9, frame 8, gear 7, first base 4 and second base 12; First lifting hydraulic cylinder 3 is fixed on first base 4, and lifting support 1 is installed on the piston rod of said first lifting hydraulic cylinder 3; One end of the frame 8 that profile is rectangular is provided with sliding bar 2; One end of said sliding bar 2 is sleeved on the lifting support 1; The upper and lower of frame 8 is respectively equipped with parallel relative first tooth bar 5 and second tooth bar 13, and the other end of frame 8 links to each other with the piston rod of advance and retreat hydraulic actuating cylinder 9; Advance and retreat hydraulic actuating cylinder 9 is hinged on the hoist cylinder seat 10; Hoist cylinder seat 10 links to each other with the piston rod of second lifting hydraulic cylinder 11; Said second lifting hydraulic cylinder 11 is fixed on second base 12 and is parallel with first lifting hydraulic cylinder 3, and gear 7 is fixed on the cantilever axletree 6 and between first tooth bar 5 and second tooth bar 13.
When crane advanced, the piston rod of the piston rod of first lifting hydraulic cylinder 3 and second lifting hydraulic cylinder 11 was in contraction state, and at this moment, first tooth bar 5 is in engagement with gear 7, owing to sliding bar 2 is sleeved on the lifting support 1, so frame 8 can only side-to-side movement.The piston rod of advance and retreat hydraulic actuating cylinder 9 is in the process of elongation; First tooth bar, 5 motions that promote to be provided with on the frame 8, first tooth bar 5 can drive with its gears in mesh 7 and rotate, because gear 7 is fixed on the cantilever axletree 6; So cantilever axletree 6 can drive the roller of crane and rotate, and has realized advancing of crane; After the piston rod of advance and retreat hydraulic actuating cylinder 9 stretches out fully; The piston rod of first lifting hydraulic cylinder 3 and second lifting hydraulic cylinder 11 stretch out with piston rod synchronously; Second tooth bar 13 is in engagement with gear 7, and when the piston rod of advance and retreat hydraulic actuating cylinder 9 shrank, frame 8 drove 13 counter motions of second tooth bar; Second tooth bar 13 can drive with its gears in mesh 8 and be rotated further, and realizes advancing continuously of crane.
When crane was retreated, the piston rod of first lifting hydraulic cylinder 3 and second lifting hydraulic cylinder, 11 piston rods all were in the state of stretching out, at this moment; Second tooth bar 13 meshes with gear 7, and the piston rod of advance and retreat hydraulic actuating cylinder 9 is in the process of elongation, and second tooth bar 13 that promotes to be provided with on the frame 8 moves; Second tooth bar 13 drives with its gears in mesh 7 and rotates; Order about cantilever axletree 6 rotations of fixed gear wheel 7, the roller that cantilever axletree 6 drives crane rotates, and has realized retreating of crane; After the piston rod of advance and retreat hydraulic actuating cylinder 9 stretches out fully; The piston rod of first lifting hydraulic cylinder 3 and second lifting hydraulic cylinder 11 are withdrawn with piston rod synchronously; First tooth bar 5 is in engagement with gear 7, and when the piston rod of advance and retreat hydraulic actuating cylinder 9 shrank, frame 8 drove 5 counter motions of first tooth bar; First tooth bar 5 drives with its gears in mesh 7 and is rotated further, and realizes retreating continuously of crane.
The blocked operation as long as the operator advances and retreat, the driving medium of first lifting hydraulic cylinder 3, advance and retreat hydraulic actuating cylinder 11 and second lifting hydraulic cylinder 13 is an emulsion.
