Abstract

The utility model relates to a hydraulic shearing fork type lift, consisting of a hydraulic system, a bracket, shearing fork arms, an oil cylinder, a chassis, an upper track, a lower track, an upper driver, a lower driver and a cross bar. End connecting holes and center connecting holes are respectively arranged at the two sides and the center of the shearing fork arm which is connected into two pairs of upper shearing forks and lower shearing forks, and the upper and the lower shearing forks are connected through the lower end connecting holes of the upper shearing fork arm and the upper end connecting holes of the lower shearing fork arm. One hole of the upper end connecting holes of the shearing fork arm of the upper shearing fork is connected with the bracket axle bed, and another hole is connected with the upper driver axle; one hole of the lower end connecting holes of the shearing fork arm of the lower shearing fork is connected with the chassis axle bed, and another hole is connected with the lower driver axle; the piston rod of the oil cylinder is connected with the cross bar of the upper shearing fork arm; the hydraulic system is connected with the oil cylinder through a pipeline; the angle changes of the upper shearing fork arm and the lower shearing fork arm are generated by the oil cylinder driving the upper and the lower forked structures, which leads to the lifting of the bracket. The utility model has strong inclination resistance capability, large lifting proportion and safety, and can be used for the transfer station of underground rubbish.

Description

Hydraulic fork type elevator

Technical field

The utility model relates to a kind of elevator, is meant a kind of hydraulic fork type elevator especially.

Background technology

At present, domestic existing garbage transfer station mostly is installed in subsurface, and rubbish container all comes with some shortcomings from the underground up-down mode that is raised to ground prior art: 1, staggered form lifting, and freight container lifting shakiness, and it is darker that melt pit is installed; 2, bed formula platform hydraulic-driven four rope liftings, casing lifting shakiness, and the melt pit cost is higher; 3, both arms supporting steel-cable mechanical elevating, steel rope easily get rusty and damage comparatively fast; 4, ground both arms tower crane lifting, double-arm tower structure floor area is bigger on the ground, cost cost height; 5, stent-type lifting, casing are in rising and decline process, and appearance is tilted and caused entire bracket distortion and damage easily, and dangerous, it is also darker that melt pit is installed simultaneously.

The utility model content

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and to propose a kind of anti-tilt capability strong, and the reduction ratio is big, and more shallow, safe in utilization, the failure-free hydraulic fork type elevator of melt pit is installed.

The purpose of this utility model can reach by following measure:

The utility model hydraulic fork type elevator includes hydraulic efficiency pressure system, carriage, cuts yoke, oil cylinder, chassis, get on the right track, lower railway, go up driving wheel, driving wheel, stull down.Described two ends and center of cutting yoke has end connection holes and central connecting hole respectively, pivot pin will be cut yoke by the center connection holes and be unified into upper and lower two pairs and cut fork, connect the corresponding yoke of cutting with stull, pivot pin by on cut fork cut yoke lower end connection holes and the upper end connection holes of cutting yoke down with upper and lower cut to pitch connect; On cut fork a hole of cutting yoke upper end connection holes connect with the carriage axle bed by pivot pin, a hole connects with the last axis of a movable block; One hole of cutting yoke lower end connection holes of cutting fork down connects with the chassis axle bed, and a hole connects with the following axis of a movable block; The piston rod of oil cylinder and on cut the yoke stull and link.Described hydraulic efficiency pressure system is installed in the waste management station, is connected with oil cylinder by pipeline, promotes up and down two groups of fork structure by oil cylinder and makes and cut yoke and change with the angle of cutting yoke down and make the carriage lifting.

The utility model has following advantage compared to existing technology:

The anti-tilt capability of the utility model hydraulic fork type elevator is strong, and the reduction ratio is big, and it is more shallow that melt pit is installed, and the occupation of land space is little, long service life, safety, reliable.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model hydraulic fork type elevator includes hydraulic efficiency pressure system, carriage 1, cuts yoke 2,7,10,11,12,13,14 and 15, oil cylinder 4, chassis 9, get on the right track 20, down rail 17 roads, go up driving wheel 19, driving wheel 18, stull 16 down.Described two ends and center of cutting yoke has end connection holes 5 and central connecting hole 6 respectively, four pivot pins will be cut yoke 2 and 10, will cut yoke 11 and 12, cut yoke 13 and 14, cut yoke 7 and 15 and be unified into upper and lower two pairs and cut fork by center connection holes 6, cut yoke 10 and 11, cut yoke 2 and 12, cut yoke 7 and 13, cut yoke 14 and 15 and connect with stull 16 respectively, four pivot pins by on cut fork the lower end connection holes 5 of cutting yoke 2,10,11,12 will upper and lowerly cut to pitch with the upper end connection holes 5 of cutting yoke 7,15,14,13 down respectively and connect; On cut fork yoke 10, the 11 upper end connection holes 5 of cutting connect with carriage 1 axle bed by pivot pin, on cut fork yoke 2, the 12 upper end connection holes 5 of cutting connect with 19 on last driving wheel; Yoke 15, the 14 lower end connection holes 5 of cutting of cutting fork down connect with chassis 9 axle beds, and yoke 7, the 13 lower end connection holes 5 of cutting of cutting fork down connect with 18 on following driving wheel; The piston rod 3 of four oil cylinders 4 with on cut yoke stull 16 and link.Described hydraulic efficiency pressure system is installed in the waste management station, is connected with four oil cylinders 4 by pipeline.When hydraulic efficiency pressure system during to oil cylinder 4 fuel feeding, the piston rod 3 of oil cylinder 4 is extrapolated, the angle of cutting yoke and cutting yoke is down changed and promote carriage and raise, when the needs carriage descends, electromagnetic valve by hydraulic efficiency pressure system is opened system circuit,, with piston rod 3 withdrawals of oil cylinder 4 and being descended, supports by carriage by the gravity of elevator self by supporting leg 8.The propradation height of the utility model hydraulic fork type elevator is 4500 millimeters, and the height of decline state is 860 millimeters.
