Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, according to paver of the present invention, comprise frame 10, be arranged on the hopper 20 in frame 10 and screed 30, paver also comprises lifting gear 40, and lifting gear 40 is arranged in frame 10 to lift screed 30.The present invention, by arranging lifting gear 40 in frame 10, when mounting and dismounting screed 30, can lift screed 30 by lifting gear 40, alleviate labor strength, also need not call other hanging devices, thus save time, save cost, raise the efficiency.
Particularly, shown in composition graphs 1 and Fig. 2, the lift arm assembly that lifting gear 40 comprises mount pad 41 and is arranged on rotationally on mount pad 41, namely lift arm assembly can be mounted opposite seat 41 at horizontal rotation in surface, also can carry out corresponding luffing operation, thus meet lifting requirements.
Particularly, lifting gear can adopt the form of structure such as masts type, telescopic boom, cable type and truss-like.Preferably, in an embodiment of the present invention, adopt masts type, masts type lifting gear structure is relatively simple, mounts and dismounts more convenient, manufactures simple, with low cost, takes up room little, and change little to existing paver.
Particularly, the lift arm assembly of masts type lifting gear comprises mobile jib 42, secondary bar 43, suspension hook 44 and lifting pulley group 45, mobile jib 42 is that axis is arranged on mount pad 41 rotationally with vertical direction, preferably, shown in composition graphs 3, mobile jib 42 is connected with thrust bearing 41a and self-aligning bearing 41b and axle sleeve with the centre of mount pad 41, thrust bearing 41a bears the load of mobile jib 42 axis, self-aligning bearing 41b bear radially bend load by, thus mobile jib 42 can be rotated about axis in horizontal plane.On the hinged mobile jib 42 of first end of secondary bar 43, the second end of secondary bar 43 and the upper end of mobile jib 42 are connected with luffing pulling device, the adjustable length of luffing pulling device thus regulate the amplitude of secondary bar 43.Suspension hook 44 is arranged on the second end of secondary bar 43 by lifting pulley group 45 adjustable ground, namely by the height of lifting pulley group 45 adjusting lift hook 44, thus is sling by screed.
Preferably, luffing pulling device adopts luffing assembly pulley 46, and luffing assembly pulley 46 is equipped with on mobile jib 42 and secondary bar 43 to regulate the amplitude of secondary bar 43.In the operating process of secondary bar 43 luffing, suspension hook 44 is driven to move, thus the operating radius of adjustment suspension hook.
More specifically, lifting pulley group 45 is had Wound steel rope and is driven by motor or rocking handle with the lifting reel 45a of adjusting lift hook 44 height, lifting reel 45a, in lifting reel 45a rotation process, and the height of adjusting lift hook 44, thus screed is lifted by crane.Luffing assembly pulley 46 has Wound steel rope to regulate the amplitude-changing drum 46a of secondary bar 43 amplitude, amplitude-changing drum 46a is driven by motor or rocking handle, in amplitude-changing drum 46a rotation process, the relative mobile jib 42 of secondary bar 43 is moved, namely the amplitude of secondary bar 43 is regulated, thus the operating radius of adjusting lift hook 44.
Preferably, lift arm assembly also comprises the transfer 47 driving mobile jib 42 to be mounted opposite seat 41 rotation, rotates mobile jib 41, thus regulate the direction of secondary bar 43 and suspension hook 44 by transfer 47.Transfer 47 can for being fixedly installed on the steering wheel on mobile jib 42, i.e. manual rotation's steering wheel thus rotate the orientation that mobile jib 42 carrys out adjusting lift hook.Transfer 47 also can adopt motor or hydraulic motor Direct driver, or through chain or gear speed governing rear drive.
Lifting gear is by arranging the degree of freedom of amplitude-changing drum 46a, lifting reel 45a and transfer 47 adjusting lift hook 44, namely lifting gear adjusts the direction of secondary bar 43 and suspension hook 44 by transfer 47, carrys out Non-follow control pulley winding make suspension hook 44 move or be elevated by amplitude-changing drum 46a and lifting reel 45a.Such suspension hook 44 has movement 3 degree of freedom in rotation in horizontal plane, one-movement-freedom-degree and vertical plane, can adapt to lifting and the installation of different operating mode diverse location.
Because the weight of screed is relatively little, generally be no more than 2 tons, lifting reel 45a, amplitude-changing drum 46a and transfer 47 all can adopt hand-driven mode, and namely lifting reel 45a, amplitude-changing drum 46a are by rocking handle manual drive, and transfer 47 is steering wheel.Adopt hand-driven mode, significantly reduce the complexity of lifting gear, make its structure simpler, to install and easy to operate, raising reliability, and can effectively reduce costs.
Preferably, lifting reel 45a and amplitude-changing drum 46a respectively correspondence is provided with anti-urgency and returns inversion set 48, thus prevents weight from dropping suddenly, ensure safety, preferably, anti-urgency is returned inversion set and is made up of crevis and ratchet, and brake type, clutch type etc. also can be adopted to prevent the device reversed.
As shown in Figure 4 and Figure 5, in preferred embodiment of the present invention, secondary bar 43 comprises body of rod 43a and is removably connected to the connector 43b at body of rod 43a two ends, the connector 43b of first end and mobile jib hinged, the connector 43b of the second end and lifting pulley group 45 and luffing assembly pulley 46 are connected.Secondary bar 43 adopts this dismountable structure design, can change the body of rod of different length as required, thus make lifting radius and rangeability larger.More preferably, body of rod 43a can adopt steel pipe, as required, can be replaced by the steel pipe of different length, in order to improve intensity, also can adopt two steel pipes, connector 43b is plugged on the two ends of two steel pipes simultaneously, reliably easy to connect simultaneously, steel pipe directly can use the screw pull rod of existing paver, thus raising material use, reduce costs, conserve space.
Shown in composition graphs 1, during paver running, construction tractor driver be usually placed on the lengthening screed disassembled in hopper.Before construction, need lengthening screed to be spliced on the basic screed in rear portion.In order to lengthening ironing board being hung the tailstock from hopper, in order to enable lifting gear, screed is lifted into the tailstock from hopper, lifting gear 40 can be arranged on the middle part of frame, when the operating radius of lifting gear 40 is enough large, also can be arranged on front portion or the rear portion of frame.During actual installation, can arrange in frame accordingly with the pedestal of bolt hole, then mount pad is bolted on pedestal, thus lifting gear 40 is removably fixed in frame.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to paver of the present invention, by arranging lifting gear in frame, when mounting and dismounting screed, screed can be lifted by lifting gear, alleviating labor strength, also need not call other hanging devices, thus save time, raise the efficiency.And it is low that paver has chassis center of gravity, the feature that fuselage deadweight is larger, after installing lifting gear, has good overturn-preventing.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
