Abstract
The utility model relates to a hydraulic wagon crane, which is characterized in that the vehicle frame of a truck (9) is not needed to be refitted specially; the entire device can be installed on a big beam (28) and a longitudinal beam (27) by a horseback-riding screw bolt (13); the source of power is obtained from the gearbox (32) of the truck (9) by a force taking device (16); the input shaft (37) of a hydraulic oil pump (35) is connected with the output shaft (36) of the force taking device (16); the slewing gear of the crane is driven by a hydraulic motor with middle speed (20) and a gear set (11). The utility model has the advantages of small size, light weight and simple structure, and is convenient for popularization and the application on the ordinary truck.
Description
The utility model relates to elevator machinery, particularly relates to the hydraulic pressure lorry-mounted crane.Existing hydraulic pressure lorry-mounted crane, volume is big, Heavy Weight, complex structure needs during installation the vehicle frame of autotruck is carried out special repacking, so the manufacturing cost height is not easy to apply on general autotruck.
Though some producer also produces some compact simplified lorry-mounted cranes, propulsion source adopts storage battery, thereby has increased the volume and weight of complete machine, cost height.And the finite energy of propulsion source, load-carrying ability is less, also is not easy to apply on general autotruck.
It is little that the purpose of this utility model provides a kind of volume, in light weight, simple in structure, easy for installation, cost is low, need not during installation the vehicle frame of autotruck is reequiped specially, its propulsion source can directly pass through power takeoff (18) and obtain from the change speed gear box (32) of autotruck (9), thereby is convenient to a kind of hydraulic pressure lorry-mounted crane of applying on general autotruck.
Principal feature of the present utility model is that whole device can be installed on the frame beam (28) with saddle clamp (13) easily, need not the vehicle frame of autotruck (9) is reequiped specially; Propulsion source is to obtain by the change speed gear box (32) of power takeoff (18) from autotruck (9), need not the additionaling power source; The revolution of hoisting crane is formed driver train by Mid-velosity Hydraulic Motor (20) and gear cluster (11) and is realized.Hydraulic oil pump (35) directly connects with power takeoff (18), need not tween drive spindle and oil pump bearing.
Fig. 1 is a working state figure of the present utility model.
Fig. 2 is off working state figure of the present utility model.
Fig. 3 is the local erection plan of the utility model.
Fig. 4 is the utility model rotary motion mechanism scheme drawing.
Fig. 5 is a connecting relation scheme drawing between the power takeoff of the utility model and autotruck change speed gear box and the hydraulic oil pump three.
Existing accompanying drawings is as follows:
Turntable (6) upper end is hinged by bearing pin (30) and crane arm (5), the lower case of turntable (6) is fixedly connected with crossbeam (28), the longeron (27) of autotruck with saddle clamp (17), bearing support (8), bearing (19), can do the rotation of 360 ° of scopes between turntable (6) top and the lower case.Amplitude oil cylinder (10) is a double acting hydraulic ram, and its two ends are hinged with crane arm (5), turntable (6) respectively.Revolution Mid-velosity Hydraulic Motor (20) shell fixes with turntable (6) lower case and connects.The output shaft of speed motor in the revolution (20) and gear cluster (11) link, and And drives turntable (6) revolution by gear cluster (11).Horizontal support legs (12) is made up of inside and outside two joints.Horizontal support legs (12) acromere is fixed and connects with frame beam (28), longeron (27) by saddle clamp (13).The internal segment of horizontal support legs (12) can be pulled out from the acromere of horizontal support legs (12), to increase the supporting span.Vertical leg (14) is made up of inside and outside two joints and bearing (16).The upper end of vertical leg (14) acromere and the internal segment of horizontal support legs (12) joint that is nested, the lower end of vertical leg (14) acromere and the internal segment of vertical leg (14) upper end be intussusception mutually, and And can regulate its length by bearing pin (15).The lower end of vertical leg (14) internal segment and bearing (16) are that thread connection ， And can carry out the length fine setting by the screw rod of bearing (16).Hydraulic efficiency operated valve (7) fixes by the railway carriage front baffle board (29) of bearing (25) with autotruck (9).Hydraulic reservoir (22) is to fix by the railway carriage front baffle board (29) of bearing support (21) with autotruck (9).Change speed gear box (32) housing of power takeoff (18) housing and autotruck (9) fixes, and power takeoff (18) input gear (34) is meshed with the output gear (33) of the change speed gear box (32) of autotruck (9).The housing of the housing of hydraulic oil pump (35) and power takeoff (18) fixes, and the input shaft (37) of hydraulic oil pump (35) links with the output shaft (36) of power takeoff (18).Power takeoff (18) drives hydraulic oil pump (35) from change speed gear box (32) the power taking And of autotruck (9), hydraulic oil pump (35) is delivered to hydraulic efficiency operated valve (7) by pressure duct (39) by low pressure line (38) oil suction And from hydraulic reservoir (22) after with the hydraulic oil supercharging, thereby driving rotational Mid-velosity Hydraulic Motor (20) and luffing hydraulic ram (10) are so that the hoisting crane normal operation.
Suspension hook (1) is hinged by bearing pin (2) and crane arm (5).Crane arm (5) is made up of two joint arms.Bearing pin (4) and hole (3) can change the usable length of crane arm (5).The engine output of car automobile (9) is carried in bar handle (31) control.
When the utility model is in off working state, earlier crane arm (5) is adjusted into minimum length, again suspension hook (1) and fixing chain (26) are linked, so that hoisting crane and front baffle board (29) fix, pull down vertical leg (14) And then the inside and outside joint of supporting leg (14) is adjusted into shortest length, vertical leg (14) is fixed on the railway carriage front baffle board (29) with fixed bearing (23), (24) again, the internal segment of regaining horizontal support legs (12) at last gets final product.
The utlity model has that volume is little, simple in structure, in light weight, easy for installation, manoeuvrable, safe and reliable, low cost of manufacture is convenient in advantages such as general truck use.
