Detailed Description

As shown in the figure: a laying machine is assisted to municipal administration street curb, including tracked vehicle 1, hydraulic pressure oil supply unit and hydraulic control device, still including the platform 2 of controlling, cantilever crane 3, the folding track that is located cantilever crane 3 outside of locating tracked vehicle 1 upper end, with the dumper 9 that folding track cooperation was used and the subassembly 10 of acting as go-between that is used for driving dumper 9 motion, folding track is including locating tracked vehicle 1's bending track 4 and articulating in a plurality of sharp tracks 5 of bending track 4 front end, bending track 4 includes sharp portion 401 and flexion 402, sharp portion 401 articulates there is slider 6, 6 sliding connection of slider is in tracked vehicle 1, still set firmly pneumatic cylinder I7 that is used for driving slider 6 on tracked vehicle 1. Further, the cantilever crane 3 comprises an upright column 301, a cantilever beam 302 rotationally connected with the upright column 301 in a single degree of freedom, a chain 304 fixedly arranged on the cantilever beam 302 and connected with a hydraulic cylinder II 303 and the free end of the hydraulic cylinder II 303, a guide wheel 305 arranged at the front end of the cantilever beam 302 and a curb lifting appliance 8 arranged at the free end of the chain 304, wherein the rear end of the cantilever beam 302 is provided with a control handle 9. The hydraulic oil supply device (not shown in the figure) and the hydraulic control device comprise manual hydraulic reversing valves, wherein the hydraulic oil supply device is arranged inside the chassis of the crawler 1, and the hydraulic control device is arranged on the control platform 2, which is not described again in the prior art.

When the crawler track vehicle is used, a driver can control the hydraulic cylinder I7 to retract through the hydraulic control device, the curved track 4 is arranged outside the crawler track vehicle 1, and the linear tracks 5 are unfolded. During specific construction, when a road section close to the stacking of the kerbs is paved, the operation and the control can be assisted by another worker, the kerbs on the stacking of the kerbs are hung by the kerbs hanger 8, and after the kerbs are hung, a driver rotates the cantilever beam 302 through the control handle 9 to enable the kerbs hung by the kerbs hanger 8 to be prevented from entering a groove to be paved. After a certain distance is paved, the crawler 1 is far away from the stacking of the kerbs, so that a worker needs to be assisted to place the kerbs on the material conveying vehicle 9 from the stacking of the kerbs by using another auxiliary hoisting tool, the material conveying vehicle 9 is forced to move to the position of the cantilever crane 3 through the stay wire assembly 10, and the operation of hoisting the kerbs is repeated. Further, when the work is completed, the hydraulic cylinder i 7 drives the slider 6, and the curved rail 4 rotates around the slider 6 while moving to the rear of the crawler 1, and the curved rail 4 is completely retracted into the crawler 1, and then the straight portion 401 is successively folded and placed on the curved rail 4 after being folded. Thus, the crawler 1 is convenient to drive and the utility model discloses a deposit.

in this embodiment, the lifting device 8 for a curb includes two claw bodies 801 hinged to each other at the middle portions, two connecting rods 802 hinged to the upper ends of the two claw bodies 801 through shafts respectively, the other ends of the two connecting rods 802 hinged to each other, a screw 803 and hand wheels 804 disposed at the two ends of the screw 803, and the two ends of the screw 803 penetrate through the two shafts respectively; the lower end of the claw body 801 is hinged with an eccentric clamping plate 805. Before use, the hand wheel 804 is adjusted to enable the claw body 801 to be larger or smaller along the screw 803 in the stroke so as to adapt to different and more kinds of curb stones. After the thickness of the kerbstone is adjusted to a proper value according to the thickness of the kerbstone, the kerbstone is placed at the lower ends of the two claw bodies 801 and pressed downwards, at the moment, the kerbstone forces the eccentric clamping plates 805 to turn outwards, then the hydraulic cylinder II 303 is started, the connecting rod 802 drives the upper ends of the claw bodies 801, and the lower ends of the claw bodies 801 are continuously tightened. Meanwhile, under the action of the gravity of the kerbstone and the friction force between the kerbstone and the eccentric clamping plate 805, the eccentric clamping plate 805 has a strong tendency of turning downwards, but is interfered by the kerbstone and does not have displacement of turning downwards towards the line, so that the clamping force and the friction force on the surface of the kerbstone can be further increased, the kerbstone is finally and firmly clamped and then hung, and the operation is simple, the use is convenient and fast, the safety is good, and the efficiency is high. Of course, the above-mentioned lifting tool 8 for kerbstone may also be used without the eccentric clamping plate 805, and the adjusting handwheel 804 is used to adjust the claw 801 to directly clamp the kerbstone for lifting.

In this embodiment, the cross sections of the curved track 4 and the linear track 5 are both in an "i" shape, the material transporting vehicle 9 includes a roller bracket i 901, a roller bracket ii 902 and a placing rack 903 arranged between the two, at least one end of the placing rack 903 is hinged to the roller bracket i 901 or the roller bracket ii 902, and the roller bracket i 901 and the roller bracket ii 902 are both provided with a lower roller 904 and an upper roller 905. The upper roller 905 is connected to the roller bracket by an elastic rod 906. The track that adopts above-mentioned I-steel formula is current section bar, and it is good to need not too much processing economic nature, and more importantly it is more suitable to adopt hinge connection to be convenient for fold and expand and is more suitable the technical scheme of the utility model, especially compare the folding more easily with the holistic deposit of tracked vehicle 1 with the double track way that current channel-section steel formed to go up gyro wheel 905 and pass through elastic rod 906 installation, during the bearing of dumper 9, elastic rod 906 is compressed, and lower gyro wheel 904 and the lower contact of following of I-steel are acted as go-between this moment, and backward movement under the pulling of subassembly 10 of acting as go-between, the wire rope of subassembly 10 of acting as go-between can be installed on the lug 907 of dumper with the lifting hook. When the material transporting vehicle 9 returns to be unloaded, the elastic rod 906 extends out, the roller support I901 and the roller support II 902 are jacked up, only the upper roller 905 contacts with the upper end face of the upper edge of the I-shaped steel at the moment, and resistance between the material transporting vehicle 9 and the I-shaped steel is greatly reduced, so that the gravity potential energy of the material transporting vehicle 9 is converted into the kinetic energy of the material transporting vehicle 9, and the front end of the final moving track of the material transporting vehicle is prepared for conveying the next curb. The driver can assist if necessary to move the trolley 9 faster to improve the efficiency of the work.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
