Description

[0001] Luffing jib placing boom [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete pumping boom device for conveying a concrete extruded from a ground concrete pump to a desired place at a high place or a far place through a conveying pipe.

More specifically, the present invention relates to a method of conveying a concrete by a conveying method using a concrete pump truck (CPT) or a conveying method using a concrete crawling boom device of a cantilever type And more particularly, to a LUFFING JIB PLACING BOOM device capable of transporting and supplying concrete to a desired place farther away.

Conventionally, in a construction site of a high-rise building such as an apartment or a building or a large-scale plant (PLANT) constructed in a large area, a concrete pump truck is used to convey concrete extruded from a concrete pump to a desired place. However, the concrete boom 28 'of the concrete pump truck is of limited length and can not convey the concrete higher or farther than the length of the boom 28'.

As shown in FIG. 2, in a high place where concrete can not be conveyed by the concrete pump truck, a column is vertically inserted into an elevator passage installed in a building to be fixed, and the column is fixed to a building by a saddle assembly And the concrete is transported from the ground to the desired place by using the raising boom 28 ', and when the concrete construction is completed at that height, the column is raised, and the racing boom rises according to the number of the buildings, There is a plaing boom 28 'that conveys the concrete to the desired location.

Further, in order to transfer the concrete to a position farther than the above-mentioned racing boom 28 ', a boom having a long length is required. As the weight of the boom increases to maintain the strength of the boom with the extended length, and the bending moment due to the weight of the boom increases as the weight of the boom increases, in order to maintain the balance, BALLANCE WEIGHT transports the concrete to a greater extent using a flipping boom 28 'mounted on the opposite side of the boom 28' about the column.

1, when the total length of the boom is not more than about 35 m, the boom 28 'is provided with a boom 28' having a boom length of more than about 35 m, ), The weight of the boom is inevitably increased in order to maintain the strength. Therefore, an excessive bending moment is generated in the column due to the increased weight. Therefore, in order to alleviate the excessive bending moment, the weight of the conveyed concrete and the feeding boom 28 'on the opposite side where the boom 28' The balance weight is installed to maintain the balance of the bending moment acting on the column.

However, the concrete pump truck of Fig. 1 or the racing boom 28 'of Figs. 2 and 3 has a CANTILEVER BEAM structure with or without a balance weight. The balance weight is applied as a means to reduce the bending moment generated in the column by the weight of the racing boom, and is not related to the strength of the racing boom.

Therefore, if the length of the cantilevered type ofplasma boom 28 'is longer to transport the concrete to a further distance, the value of the sectional properties of the plush boom must be increased to maintain the strength suitable for the length The weight of theplating boom 28 'is inevitably increased, and the weight of the conveyed concrete is increased due to the increased length, so that the shearing force and the bending moment are excessively generated in theplitting boom 28'. In order to overcome this problem, the cross-sectional structure of theplitting boom 28 'is enlarged and the weight of the balance weight is increased. Therefore, the structure of the column for supporting the boom 28' There is a limit to expanding. Due to such a problem, there is a limit in that the length of the currently used cantilever type ofplasma boom can not exceed about 50 m.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a flat boom, in which the length of a flaming boom is prolonged without increasing a shearing force and a bending moment generated in the flaming boom, And to provide a roughing platform flipping boom device that extends the area and space for transporting concrete by conveying concrete where it can not be transported.

In order to achieve the above-mentioned object, the present invention provides a roughing andplitting boom apparatus for forming a simple support point in the middle of a longitudinal direction of a racing boom, The shearing force and the bending moment generated in the racing boom can be reduced to reduce the weight of the racing boom at the same length as that of the conventional cantilever type racing boom. In the case of extending the length of the racing boom, So that the length of theplating boom can be extended.

As described above, the roughing and plaing boom according to the present invention, which has the same value as the maximum shear force and bending moment generated in the conventional cantilever type ofplasma boom, Can be extended by at least 2 times. The area for conveying concrete can be expanded up to 4 times in the horizontal plane. By the undulation operation of the roughing house, the undulation operation of the racing boom and the turning operation of the racing boom and the rotation of the turntable, It is possible to expand the spatial volume up to 8 times so that the efficiency of concrete conveying means is maximized to shorten the air and to reduce the required quantity of equipment and to reduce the fixed cost due to the installation and operation, Competitiveness can be increased.

The weight of the racing boom 28 ', 28 gradually increases from the end to the inner side, and the load distribution is a distribution condition of a right triangle shape in the section of B to C. In FIG. 8, Since the shearing force and the bending moment generated in the lapping body 18 of the section A to the section B do not increase in proportion to the length, the cross-sectional characteristic values of the roughing body 18 can be made to have the same cross- Distribution load condition. 7, a load generated at a position where the conventional cantilever-structureplicing boom 28 'is supported is referred to as Wc (cANTILEVER), and a load generated at a position where theplicing boom 28 is simply supported in FIG.

As shown in FIG. 8, the two-point simple supportive racing boom 28 according to the present invention has a maximum shearing force V _Sb = Ws · L / 4 at the point of simple support point B of the raising boom 28, the moment is the same value as the maximum shear force and the maximum bending moment generated in the Wc = conventional cantilever structure flat racing boom (28 ') in Figure 7, so as Ws ^{_{M SB = -Ws · L 2/}} 24. On the other hand, the shearing force generated at the simple support point A of the roughing house 18 having the same cross-sectional structure is V _SA = Ws · L / 6, the bending moment generated at the same position is M _SA = 0, ~ B maximum bending moment generated in the region is at the position of L / 6 from the point a _{M L / 6 = -Ws · L} 2/72 of the cantilever structure is a two-fold extension in the length 7 as flat racing boom (28 ' The maximum shear force at point A is only 1/6 (16.7%) as V _CA = Wc · L and V _SA = Ws · L / 6, and the maximum bending moment is M _CA = -Wc · L ^2/3 and _{M L / 6 = -Ws · L} 2/72 only 1/24 (4.2%) and do not need a large section of the attribute value of the roughing house 18, so weight reduction can be a roughing house 18 The conveying distance of the concrete can be doubled without increasing the weight.
