THE CABLE CRANE FOR A CIVIL ENGINEERING AND CONSTRUCTION WORKING

摘要

The present invention includes an engine 11 and the hydraulic pump 12, using the hydraulic motor 13 performing a hoisting drum with drive (14) (15) to a, and the drum 14 is provided with drive unit 15 as a brake (16, 17) with the same spacing mechanism (18) to the brake (10) ; The drive section 10 of the driving drum 15 and the traveling grinding hypothesis that the same device separation mechanism (18) (5A) and a distance gisak (5B) the central chamber, which is installed to maintain the tension (20); The central thread running Isaac (5A) and a distance of 20 gisak (5B), the driving (10) the winding drum 14 winding Isaac (5C) for guiding the guide pulley is part of the hypothesis to 30; Is linked to the drive unit 10 is provided with dozens of frame 41, the lower and the middle portion to form a tower of the drive-side hinge 45, 45 'to 40; Is coupled to the upper portion of the drive-side tower 40 via the guide pulley driving unit 30 is erased (5A) and a distance gisak (5B), the winding Isaac (5C) for guiding the guide pulleys (51, 52, 53 ), and the tower (fixed socket on the ground to support the 40) (35) and, the fifth block tension Isaac (5D) attached to 36 is fixed to the bracket is connected to each other by a pivoting pin head 54 (55 ') coupled to the tension Isaac socket coupled to the mainstay (55) and a reverse side of the tower head bracket (56 to couple mainstay (5E) are connected to each other in the 10th block 75 of 70') socket (56) driving the driving side made of a tower-side head (50) to install the (1); The installation in correspondence to the driving-side tower 40 is provided with several tens of frames (61), inverted to form a hinge (45 ") at the lower side the tower (60); and in the upper portion of the reverse side of the tower (60) Each of the guide pulleys (51, 52, 53) to guide the traveling grinding (5A) and a distance gisak (5B) a guide pulley installed to circulate by connecting the driving side are combined with each other provided on the tower head (50) 71, 72 and hoisting Isaac (5C) and, 10 to be rotated by a stopper (5E) is fixed so as to connect the kingpin (44) is connected to the stopper socket 56 of the driving-side tower head (50) coupled to the primary block 75 and the tower fixed to the ground to support the socket (60, 35 ') and the fifth block 36' Isaac tension bracket (5D) attached to the connection to each other (76 ') The tension Isaac socket 76 to reverse side (2) having a reverse side of the tower head mounting portion (70); characterized by comprising, including ; Accordingly, the present invention, each far After reduction of the hypothesis of the cable between the towers fell 2 renovated using hooks or bucket, cost carriers such as transporting construction materials into power, as well as safe and rapid transport of construction materials and concrete dams or bridges it is effective to perform such as the construction of. ; In addition, by forming the hinge (Hinge) provided in the lower portion of the tower to take to perform a hinge-type role for the 360 direction, and as well as the intermediate If you install the hinge in part by the lower hinge is buried in the earth, and my role is not to take the place of the middle hinge, by fixing the tension in the back Isaac distances by increasing the angle between the tower and the tower dramatically reduce the load on the tower has the effect of.
