The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figure 1, according to paver of the present invention, comprise frame 10, be arranged on hopper 20 and screed 30 on frame 10, paver also comprises lifting gear 40, and lifting gear 40 is arranged on frame 10 with lifting screed 30.The present invention, by lifting gear 40 is set on frame 10, when installation and removal screed 30, can lift screeds 30 by lifting gear 40, alleviate labor strength, also need not call other hanging devices, thereby save time, save cost, raise the efficiency.
Particularly, shown in Fig. 1 and Fig. 2, lifting gear 40 comprises mount pad 41 and is arranged on rotationally the lift arm assembly on mount pad 41, and lift arm assembly can rotate relative to mount pad 41 in horizontal plane, also can carry out corresponding luffing operation, thereby 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 conveniently, manufactures simply, with low cost, takes up room little, and changes 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 be take vertical direction and is arranged on rotationally on mount pad 41 as axis, preferably, shown in Fig. 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 axial load of mobile jib 42, self-aligning bearing 41b bear radially bend load by, thereby make mobile jib 42 to rotate around 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 the luffing pulling device, thus the amplitude that secondary bar 43 is regulated on the adjustable ground of the length of luffing pulling device.Suspension hook 44 is arranged on the second end of secondary bar 43 by lifting pulley group 45 adjustable grounds, by the height of lifting pulley group 45 adjusting lift hooks 44, thereby screed is sling.
Preferably, the 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 secondary bar 43 luffing operating process, drive suspension hook 44 motions, thereby adjust the operating radius of suspension hook.
More specifically, lifting pulley group 45 has the lifting reel 45a of Wound steel rope with adjusting lift hook 44 height, and lifting reel 45a drives by motor or rocking handle, 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 amplitudes, amplitude-changing drum 46a drives by motor or rocking handle, in amplitude-changing drum 46a rotation process, makes relative mobile jib 42 motions of secondary bar 43, regulate the amplitude of secondary bar 43, thus the operating radius of adjusting lift hook 44.
Preferably, lift arm assembly also comprises the transfer 47 that drives mobile jib 42 to rotate relative to mount pad 41, by transfer 47, rotates mobile jib 41, thus the direction of regulating secondary bar 43 and suspension hook 44.Transfer 47 can, for being fixedly installed on the steering wheel on mobile jib 42, rotate thereby manually rotate steering wheel the orientation that mobile jib 42 carrys out adjusting lift hook.Transfer 47 also can adopt motor or hydraulic motor directly to drive, 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 hooks 44, be that lifting gear is adjusted the direction of secondary bar 43 and suspension hook 44 by transfer 47, manually control the pulley winding by amplitude-changing drum 46a and lifting reel 45a suspension hook 44 is moved or lifting.Suspension hook 44 has 3 degree of freedom of movement in rotation, one-movement-freedom-degree and the vertical plane in horizontal plane like this, can adapt to lifting and the installation of different operating mode diverse locations.
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 lifting reel 45a, amplitude-changing drum 46a are by the rocking handle manual drive, and transfer 47 is steering wheel.Adopt hand-driven mode, effectively reduced the complexity of lifting gear, make its structure simpler, installation and easy to operate, improve reliability, and can effectively reduce costs.
Preferably, lifting reel 45a and amplitude-changing drum 46a correspondence respectively are provided with anti-anxious time inversion set 48, thereby prevent that weight from dropping suddenly, guarantee safety, preferably, the anti-anxious inversion set that returns is comprised of crevis and ratchet, also can adopt brake type, clutch type etc. to prevent the device of reversion.
As shown in Figure 4 and Figure 5, in preferred embodiment of the present invention, secondary bar 43 comprises body of rod 43a and removably is connected to the connector 43b at body of rod 43a two ends, and connector 43b and the mobile jib of first end are hinged, and 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 as required the body of rod of different length, thus make lift by crane radius and rangeability is 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 simultaneously, easy to connect reliable, steel pipe can directly be used the screw pull rod of existing paver, thereby the raising material use, reduce costs, conserve space.
Shown in Fig. 1, during the paver running, construction the tractor driver usually be placed on the lengthening screed disassembled in hopper.Before construction, need to be spliced on the basic screed in rear portion lengthening screed.In order to hang the tailstock from hopper by lengthening ironing board, in order to make lifting gear screed can be lifted into from hopper to the tailstock, lifting gear 40 can be arranged on the middle part of frame, in the situation that 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, the corresponding pedestal with bolt hole can be set on frame, then mount pad be bolted on pedestal, thereby lifting gear 40 removably is fixed on frame.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
According to paver of the present invention, by lifting gear is set on frame, when the installation and removal screed, can lift screed by lifting gear, alleviate labor strength, also need not call other hanging devices, thereby save time, raise the efficiency.And it is low that paver has the chassis center of gravity, the characteristics that the fuselage deadweight is larger, after lifting gear is installed, have 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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
