The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 1 shows conveying cylinder according to concrete pump truck of the present utility model and is installed on partial schematic diagram on the special-purpose vehicle frame in chassis, and Fig. 3 shows the schematic perspective view according to the special-purpose vehicle frame in chassis of concrete pump truck of the present utility model.As shown in figures 1 and 3, the back axle installation portion 10a of the special-purpose vehicle frame 10 in chassis has following convex portion 10b, this time convex portion 10b can reduce the setting height(from bottom) of back axle 200 (schematically illustrated in Fig. 1), so, the height of the vertex P1 of the erecting equipment on the back axle decreases, under the situation that the distance H 1 of carrying cylinder 100 with back axle erecting equipment vertex P1 remains unchanged, can make and carry the inclination angle a of cylinder 100 to reduce, in addition, tail boom 13 back-offs are installed, and can further reduce the inclination angle a that carries cylinder 100.
Reduce conveying cylinder 100 inclination angle a by above measure, made and carry the suction of cylinder highly to reduce, thereby improved the suction amount in the unit time of carrying cylinder 100.
The conveying cylinder that Fig. 2 shows concrete pump truck shown in Figure 1 is installed on the schematic top plan view on the special-purpose vehicle frame in chassis, and Fig. 3 shows the schematic perspective view according to the special-purpose vehicle frame in chassis of concrete pump truck of the present utility model.As shown in Figures 2 and 3, the inner width H2 of rear overhang part 10c is greater than the inner width H5 of back axle installation portion 10a, and so, back axle installation portion 10a can keep original width, and this provides assurance to maximally utilising existing back bridge device.Rear overhang part 10c widens, the result carries the installing space S of cylinder 100 (illustrated two among Fig. 2 and carried cylinder) to strengthen, and carries the layout width H3 of cylinder 100 to strengthen thereupon, promptly carries the diameter of cylinder 100 can strengthen from designing, so, carry the suction amount of cylinder in unit time also to increase thereupon.
By above description as can be seen, by the layout width H3 that reduces to carry the inclination angle a of cylinder 100 and strengthen conveying cylinder 100, suction amount in the unit time of transmission pump 100 has increased, the feed rate of pump truck can improve 20%, thereby the technology upgrading space is provided for the overall performance of concrete pump truck.
Fig. 3 to Fig. 6 shows the structure according to the special-purpose vehicle frame in chassis of concrete pump truck of the present utility model.To shown in Figure 6, the special-purpose vehicle frame 10 in chassis comprises left longeron 11, right vertical beam 12, front cross rail 16, some intermediate transverse girders 15 and 17, back axle mounting rail 14, tail boom 13 and some connection structures that links to each other with miscellaneous part as Fig. 3.Wherein, the back axle installation portion 10a of left side longeron 11 and right vertical beam 12 is with respect to other part indents, and back axle installation portion 10a is outstanding downwards with respect to other parts, form convex portion 10b down, the existence of following convex portion 10b can make the setting height(from bottom) of back axle mounting rail 14 reduce, so, the vertex P1 of the erecting equipment on back axle decreases.
Based on the special-purpose vehicle frame in above-mentioned chassis, the method for improving of concrete pump truck suction amount of the present utility model is as follows: provide a kind of chassis special-purpose vehicle frame 10, the width of rear overhang part 10c that makes the special-purpose vehicle frame in chassis is greater than the width of the back axle installation portion 10a installing space with the conveying cylinder that increases concrete pump; Make the left longeron 11 at back axle installation portion 10a place of the special-purpose vehicle frame in chassis and right vertical beam 12 have following convex portion 10b reducing the setting height(from bottom) of back axle, and tail boom 13 is tipped upside down on the left longeron 11 of the special-purpose vehicle frame in chassis and the right vertical beam 12 to reduce the mounted angle of conveying cylinder; And the conveying cylinder 200 that a kind of concrete pump is provided, suitable with the installing space and the mounted angle of the conveying cylinder of the special-purpose vehicle frame 10 in chassis to promote the suction amount of concrete pump truck in unit time.
Preferably, the left longeron 11 of rear overhang part 10c of the special-purpose vehicle frame 10 in chassis and the inner width between the right vertical beam 12 are limited between 730mm～830mm.
Preferably, the following prominent of following convex portion 10b of the special-purpose vehicle frame 10 in chassis highly is limited between 60mm～100mm.
Now special-purpose vehicle frame in chassis and the existing general vehicle frame with concrete pump truck of the present utility model compares:
Present pump truck chassis all is to adopt traditional general heavy card chassis to reequip.Heavily block the chassis and produce the date in enormous quantities early, its most of parts have all adopted mould molding, have formed standard size.The chassis side rail on general heavy card chassis generally adopts the general steel plate compression molding.Owing to be subjected to conditionalities such as technology, equipment, it highly, change width can not be too many; Therefore cause its vehicle frame inner width to be generally less than 700mm; The back axle mounting rail apart from vehicle frame upper surface drop less than 100mm.
The utility model is by adopting the high tensile steel plate welding manner, carrying cylinder to strengthen vehicle frame inner width (as shown in Figure 2) by the place, reduce the setting height(from bottom) of back axle, thereby can do big input cylinder diameter in design, can reduce input cylinder inclination angle during installation, thereby improve the suction amount of pump truck in unit time.Tail boom tips upside down on two and has improved the stressed of vehicle frame effectively above the longeron (as shown in Figure 3), has improved the service life of vehicle frame greatly.According to chassis of the present utility model special-purpose vehicle frame said structure characteristics, can improve pump truck feed rate 20% from designing, the weight of vehicle frame can reduce by 25%.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
