Definitions

  • the present invention relates to a transportation equipment of concrete or other building materials, in particular to a boom of concrete pump truck and a concrete pump truck with the boom.
  • a concrete transportation pump truck (abbreviated as “concrete pump truck” or “pump truck”) is a concrete transportation apparatus which a concrete pump and an articulated boom are mounted on an automobile chassis, a concrete delivery pipe is laid along the boom, and concrete is outputted through a terminal hose ultimately.
  • the articulated boom has folded state and unfolded state. In the folded state, the boom is folded onto the chassis, so that the pump truck can run on the road. In the unfolded state, the boom is unfolded, so that concrete can be poured over a long distance.
  • the folded forms of the boom mainly include R-shaped, Z-shaped, and RZ-shaped folded forms.
  • the R-shaped folded form refers to that the boom sections can be folded in a coiled or rolled up manner in a first direction (e.g., clockwise direction), and can be unfolded in a second direction being reversed to the first direction (e.g., counter-clockwise direction).
  • the Z-shaped folded form refers to that the boom sections can be folded or unfolded in reversed direction in turns.
  • the RZ-shaped folded form is a combination of R-shaped and Z-shaped folded forms. More boom sections are required in order to obtain a longer concrete transportation distance.
  • the pump truck is inevitably subjected to restrictions of the road conditions when it runs on the road, for example, when the boom is in the folded state, the length, width, and height of the pump truck are subjected to restrictions of the road transportation rules. Therefore, it is impossible to increase boom sections freely.
  • the number of the boom sections on a concrete pump truck is usually not more than 6.
  • the object of the present invention is to provide a boom of concrete pump truck, which can extend the concrete delivery range as far as possible when it is in unfolded state and has high flexibility and operability, but essentially doesn't increase the overall dimensions of the pump truck when it is in folded state.
  • the present invention provides a boom of concrete pump truck, which has a folded state and a unfolded state, and comprises seven boom sections articulated in sequence, wherein, in the folded state, the seven boom sections are essentially arranged in five straight lines staggered to each other, and at least the last two boom sections are in the same straight line.
  • the fourth boom section to the seventh boom section are in two straight lines among the five straight lines.
  • the fourth boom section and the fifth boom section are in one of the two straight lines, and the sixth boom section and seventh boom section are in the other one of the two straight lines.
  • the first boom section and the second boom section are in a first longitudinal plane
  • the fourth boom section to the seventh boom section are in a second longitudinal plane
  • the first longitudinal plane and the second longitudinal plane are parallel to each other and spaced from each other
  • the third boom section extends between the first longitudinal plane and the second longitudinal plane.
  • the first boom section to the third boom section are folded in a first direction
  • the fourth boom section is folded onto the third boom section in a second direction that is reversed to the first direction
  • the sixth boom section is folded onto the fifth boom section in the first direction.
  • the fifth boom section, the sixth boom section and the seventh boom section are in one of the two straight lines, while the fourth boom section is in the other one of the two straight lines separately.
  • the first boom section and the second boom section are in a first longitudinal plane
  • the fourth boom section to the seventh section are in a second longitudinal plane
  • the first longitudinal plane and the second longitudinal plane are parallel to each other and spaced from each other
  • the third boom section extends between the first longitudinal plane and the second longitudinal plane.
  • the first boom section to the third boom section are folded in a first direction
  • the fourth boom section is folded onto the third boom section in a second direction that is reversed to the first direction
  • the fifth boom section is folded onto the fourth boom section in the first direction.
  • the five straight lines are essentially parallel to each other.
  • the present invention further provides a concrete pump truck, which comprises an automobile chassis, a revolving platform, and a boom, with the boom mounted on the automobile chassis via the revolving platform, wherein, the boom is the boom provided in the present invention.
  • a boom that has seven boom sections can be provided, and therefore the concrete delivery range can be extended to some degree.
  • the seven boom sections are essentially arranged in five straight lines staggered from each other; therefore, the overall dimensions of the sections can be decreased greatly, and the requirement for road conditions can be met easily.
  • at least the last two boom sections are in the same straight line; therefore, the flexibility and operability of the boom for material distribution can be greatly improved.
  • the concrete pump truck mainly comprises an automobile chassis, a revolving platform, and a boom, wherein, the boom is mounted on the automobile chassis via the revolving platform 8, so that the boom can revolve around the revolving platform 8 as required, and preferably can revolve 0°-360°.
  • the concrete pump truck provided in the present invention has seven boom sections articulated in sequence, i.e., there are the first boom section to the seventh boom section when counted from the first boom section 1 connected to the revolving platform 8.
  • the boom having seven boom sections in the present invention can increase the concrete transportation distance to some degree.
  • the seven boom sections are essentially arranged in five straight lines staggered from each other; in other words, the seven boom sections form a "five-layer” structure when they are folded, rather than a "seven-layer” structure in the conventional meaning (no matter the structure is a R-shaped structure or Z-shaped structure); therefore, the overall dimensions of the boom sections, especially the height of the pump truck, can be reduced greatly, and the requirement for road conditions can be met easily.
  • the boom when the boom is in the folded state, at least the last two boom sections are in a same straight line; therefore, the flexibility and operability of the boom for material distribution can be greatly improved.
  • the seven boom sections can be folded into a "five-layer" structure just because several sections are in the same straight line.
  • three boom sections can be arranged in a same straight line, so that the seven boom sections can be arranged in five straight lines; or, four boom sections can be arranged in pairs in two straight lines respectively, so that the seven boom sections can be arranged in five straight lines.
  • the two or three boom sections arranged in the same straight line can be any adjacent sections among the seven boom sections.
  • the fourth boom section to the seventh boom section i.e., the last four boom sections
  • a terminal hose is connected to the last boom section to transfer concrete to a specified working place during the work. Therefore, the flexibility and operability of the boom for material distribution can be improved greatly by arranging the last several sections in straight lines.
  • Figure 1(a) and 1(b) show an embodiment of the present invention.
  • the fourth boom section 4 and the fifth boom section 5 are in the same straight line
  • the sixth boom section 6 and the seventh boom section 7 are in the same straight line.
  • the two straight lines are the last two straight lines among the five straight lines of the boom in the present invention. In this way, the last four boom sections are arranged in two adjacent straight lines, so that the overall dimensions of the pump truck can be reduced, and the flexibility and operability of the boom for material distribution can be greatly improved.
  • the first longitudinal plane comprising the first boom section 1 and the second boom section 2 and the second longitudinal plane comprising the fourth section 4 to the seventh boom section 7 are spaced from each other, and connected to each other via the third boom section 3, i.e., the third boom section 3 is designed into a curved shape, so that one end of the third boom section 3 is positioned in the first longitudinal plane and the other end of the third boom section 3 is positioned in the second longitudinal plane.
  • the first boom section 1 to the third section 3 are folded in a first direction (clockwise direction as shown in Figure 1(b) ), the fourth boom section 4 is folded onto the third boom section 3 in a second direction (counter clockwise direction) being reversed to the first direction, and the sixth boom section 6 is folded onto the fifth boom section 5 in the first direction.
  • the boom can be unfolded in the reversed direction.
  • Figure 2(a) and 2(b) show the second embodiment of the present invention.
  • the fifth boom section 5, the sixth boom section 6, and the seventh boom section 7 are in the same straight line
  • the fourth boom section 4 is in the other adjacent straight line separately.
  • the last three boom sections are arranged in the same straight line, so that the flexibility and operability of the boom can be improved; in addition, in some cases that the space is limited, the concrete can also be transported to a specified working place successfully.
  • the seven boom sections can be arranged in two longitudinal planes in this embodiment, so as to reduce the height of the pump truck and fully utilize the space in width direction above the chassis of the pump truck. It will not be described repeatedly herein.
  • the first boom section 1 to the third section 3 are folded in a first direction (clockwise direction as shown in Figure 2(b) ), the fourth boom section 4 is folded onto the third section 3 in a second direction (counter clockwise direction as shown in Figure 2(b) ) being reversed to the first direction, and the fifth boom section 5 is folded onto the fourth boom section 4 in the first direction.
  • the space occupied by the boom in the folded state can also be reduced effectively; therefore, the overall dimensions of the pump truck in travel state can be reduced, and the requirement for road conditions can be met easily.
  • the five straight lines formed by the seven boom sections are essentially parallel to each other. That is to say, when the boom sections are in the folded state, all of them are essentially level; therefore, the structure is stable and easy to arrange relatively.
  • a concrete pump truck mainly comprising an automobile chassis, a revolving platform, and a boom, wherein, the boom is mounted on the automobile chassis via the revolving platform 8, and the boom is the boom provided in the present invention.
  • the present invention further provides some other embodiments of the boom that comprises seven boom sections, as shown in Figures 3-10 . Hereafter these embodiments will be described.
