Abstract

The invention discloses a mechanical driving lifer for a dumper. The mechanical driving lifer consists of a lifting support frame, a lifter, a parking device and a transmission, wherein the transmission is driven by power of the engine; the mechanical driving lifer upwards drives through the driving lifter of the transmission, so that a packing case connected to the top of the mechanical driving lifer upward moves and the dumping effect of the dumper is achieved.

Description

Tip lorry mechanical drive lifter

Affiliated technical field

Patent of the present invention is a kind of mechanically operated tip lorry lifter, it simple in structure, easy to maintenance.

Background technology

At present, mechanically operated tip lorry lifter is made up of lifting support frame, lifter, stopping device, tooth case.Power process reverse gearing device with driving engine is transferred to the tooth case, is transferred to lifter top bonded assembly container again and moves up and down.But, the driving engine gear must be moved to a gear before the operation, when connecing at a high speed, lifter speed is speeded as advancing at other, can not the lifting container when loaded vehicle, can cause driving engine to stop going up rotation like this.

Summary of the invention

Patent of the present invention be for the complex structure that solves hydraulic pressure tipping bucket lifter in the past, cost height, operation cumbersome, the oil sealing easy oil leakage, maintenance is inconvenient, the shortcoming that cost of maintenance is too high, low, simple in structure, the easy to maintenance advantage of patent lifter cost of the present invention.

Patent of the present invention solves the technical scheme that its technical matters adopts: at lifting support frame, and lifter, stopping device, under the connection of tooth case, the mechanical drive mode that total adopts is inclined upwardly the tip lorry container and reaches the purpose of tipping bucket.

The beneficial effect of patent of the present invention put control lever in place in when operation, need only step on engine throttle, just can make tip lorry reach the effect of tipping bucket, and is simple to operation.

Below in conjunction with drawings and Examples patent of invention is further specified.

Specific embodiments

In Fig. 1, support (1) is welded on the crossbeam of automobile, the hole of upper end is connected with the hole of supporting straight-arm (3), supporting another hole of straight-arm (3) is connected with the hole of supporting curved boom (4) lower end, tween drive shaft is connected with the hole of lifter top cover (10), support the front end that curved boom (4) upper end hole is connected in the automobile container lower curtate, promote the container up-and-down movement, revotating card (2) and rotating disc (14) also rotation simultaneously.

In embodiment illustrated in fig. 2, output spline (50) inserts in bevel pinion (6) female splines, engagement large bevel gear (5), centre hole has square key to be connected with screw mandrel (8) bottom to be rotated, drive nut (7) and be connected on sliding tube (12) the top top cover (10), promotion support curved boom (4) is gone up the bonded assembly container and is moved up and down.

In the embodiment shown in fig. 3, tooth case handle (19) promoted forward when the railway carriage need were up, tooth case pull bar (20) the pulling tooth case gear arm (22) that is connected on the handle is transformed into the power of tooth case on the lifter from rotating vehicle ', tooth case handle (19) also will be fixed on tooth case handle (19) top when promoting forward drag-line spurs forward, makes the eccentric torque arm of power-transfer clutch (33) tighten the power-transfer clutch drag-line.Again reverse graft device handle (18) is promoted forward, be connected in the reverse gearing device gear arm (16) on reverse gearing device pull bar (17) the pulling reverse gearing device (15) on the handle, make reverse gearing device (15) be in the place of reversing gear, it also is the lifter rising portion, make tooth case (23) powered rotation to lifter, when lifter is up, also make the railway carriage that is connected in the upper end up, the pull bar (35) that is connected in aftbody when driving to top dead point is along with railway carriage rises, pulling is connected on the lever (36), the other end is connected on the middle check screw of communtation arm (37) rotatable, the upper end is moved backward, pulling is connected in the power-transfer clutch drag-line of communtation arm (37) upper end, make the power-transfer clutch drag-line by the eccentric torque arm (24) of the up power-transfer clutch in the stopping device clamping plate, to the two-in-one clamp of power-transfer clutch drag-line (32), pulling power-transfer clutch torque arm (28) is left power-transfer clutch and railway carriage stops up.When the railway carriage need are descending, reverse gearing device handle (18) is promoted backward, the clutch gear-shift arm (16) that is connected in (17) one on reverse gearing device pull bar is promoted forward, make reverse gearing device (15) be in the forward gear place, place, the position of lifter decline just, at this moment the driving engine gear must be in 1 gear, make tooth case (23) powered rotation to lifter, when lifter descends, railway carriage also descends simultaneously, when bottom dead point, the pull bar (35) that is connected in aftbody promotes to be connected on the lever (36) to descending, the other end is connected on the middle check screw of communtation arm (37), move backward rotatable communtation arm (37) lower end that makes, and pulling is connected in the power-transfer clutch drag-line of communtation arm (37) lower end, and the power-transfer clutch drag-line is passed on the two-in-one drag-line clamp of power-transfer clutch (32) by the eccentric torque arm of descending power-transfer clutch (34) in the stopping device clamping plate, power-transfer clutch torque arm (28) pulling power-transfer clutch leaves, and railway carriage stops.

In another embodiment shown in Figure 4, from the engine-drive to the reverse gearing device on (15), be transferred to the tooth case (on the outside end of 45) De Hua Key double-headed shaft (38) through output shaft, the other end in tooth case (45) with the hole bearing fit of internal tooth bevel gear (40), female splines double end tooth (43) returns at the fork-like farm tool used in ancient China of shift fork and stirs engagement down, the other end meshes of internal spline axle (44), and the other end is stretched out tooth case shell and connected transmission shaft outward, promotes vehicle '.When female splines double end tooth (43) engagement internal tooth bevel gear (40), transmission of power is arrived on the bevel gear (46), female splines and the short big spur gear of castellated shaft (47) spur pinion (49) fit engagement (48) make middle output spline (50) the engagement bevel pinion (6) of big spur gear (48) to lifter container be moved up and down transmission of power.
