Embodiment 1
[0049] Such as Figure 1~8 As shown, a steel column assembly device includes a fixed part of the steel column foundation, a connection part between the steel column and the device, a lifting strut part, and a driving part;
[0050]The fixed part of the steel column foundation includes an underframe and special hook bolts. The special hook bolts 13 fix the underframe on the ground foundation. The underframe is composed of two outer underframes 16 and two inner underframes 17. There are pin holes in the middle of the frame for connecting other parts;
[0051] The connecting part of the steel column and the device includes two connecting arms 10 and hook bolts 11 suitable for the size of the steel column 7 side angle steels. The connecting arm 10 includes a short horizontal side and a long horizontal side, and the two are connected by a hypotenuse. The end of the short horizontal side of the connecting arm 10 is provided with a hole to connect with the pin shaft 14 on the chassi...

The invention discLoses a steeL coLumn assembLing device and a using method thereof. The device comprises a steeL coLumn basic fixing portion, a steeL coLumn and a device connecting portion, a Liftingsupporting rod portion and a driving portion; the steeL coLumn basic fixing portion comprises a base frame and a speciaL-shaped hook boLt, the steeL coLumn and device connecting portion comprises twoconnecting arms appLicabLe to the size of steeL coLumn side corner angLe and a hook boLt, the Lifting supporting rod portion comprises two supporting rods, the bottoms of the supporting rods are provided with rotating shafts to be connected with the base frame, the top ends of the two supporting rods are each provided with a hoLe for containing through pins; the driving part comprises a set of puLLeys with steeL wire ropes and a manuaL winch matched with the steeL wire ropes; the steeL wire ropes are wound around the puLLeys fixed to the Lifting supporting rods to be connected with Lifting hooks on steeL coLumns. The device is simpLe in structure, portabLe in transportation and easy to instaLL and use; accordingLy, compared with an existing construction method, the operation time is shortened, and the construction efficiency is improved; the requirement for the construction environment is Low.
Description
technical field [0001] The invention relates to a steel column erecting device and a method for using the same, belonging to the field of electrified railways. Background technique [0002] In the construction of domestic electrified railway projects, there are many disadvantages in the method of erecting steel columns. The existing methods all rely on heavy and large mechanical equipment, such as truck cranes and rail cranes. This has caused a series of problems such as high construction cost, long operation time, and high requirements for the working environment. The above problems are precisely the key and difficult points that the construction unit urgently needs to solve. [0003] Based on the above problems, we have developed a low-cost, high-efficiency steel column assembly device. Contents of the invention [0004] The present invention aims to provide a steel column erecting device, which solves the problems of high construction cost, long working time and high ...
