Then hoisting the transmission trolley by using hoisting equipment, positioning the transmission trolley above the standard knot 211 of the guide rail 21, connecting and fixing the transmission trolley and the suspension cage 22, and adjusting the door lock, wherein all doors can be opened and closed flexibly.
When the standard knot 211 of the guide rail 21 is installed, a gradienter or a line weight is used for measuring the verticality of the guide rail 21, the verticality of each vertical pipe of the guide rail 21 in two adjacent directions is protected to be less than or equal to 1/1500, if the verticality needs to be adjusted, adjusting steel plates with different thicknesses can be filled between a chassis and a base platform at the position of the anchor bolt, and when the guide rail 21 is adjusted to be vertical, 4 anchor bolts are tightly pressed by a torque of 350 N.m. The perpendicularity of the door 221 of the suspension cage is adjusted by the same method, so that the perpendicularity of the door 221 of the suspension cage is less than or equal to 1/1000 in two similar directions.
Since the travel of the lift 2 increases with the building of the pylon 3, the heightening of the subsequent rail 21 may in particular comprise the following steps: firstly, wiping the pipe joints at the two ends of the standard joint 211 of the guide rail 21 and the pin of the rack 231 completely, and adding a small amount of lubricating grease; the constructor goes through the ladder in the cage 22 and the trap door 222 to the top of the cage 22, hooks the standard section 211 through the hanger rod arranged on the top of the cage 22 and hangs the standard section 211 to the top of the cage 22, closes the trap door 222 and starts the elevator 2. When the cage 22 rises to approach the top of the guide rail 21, the vehicle should be inching to run until the top of the installed guide rail 21 approaches about 300mm and stops; the standard knot 211 is lifted by a suspender, and the lifting hook is put down by aligning with a vertical pipe of the lower standard knot 211 and a pin hole on the rack 231 and then fastened by a bolt.
The standard knots 211 are connected in sequence according to the method until the required height is reached, the attachment frames 212 are installed at the same time along with the continuous heightening of the guide rail 21, and the installation verticality (inclination) of the guide rail 21 is checked, so that the construction personnel must clearly understand the installation distance of the attachment frames 212 and the requirement of the maximum free end height of the guide rail 21. At the same time, the connection requirements, adjustment methods, etc. of the parts of the attached frame 212 must be grasped. After each attachment bracket 212 is mounted, the mounting verticality (inclination) of the guide rail 21 must be checked, and the attachment bracket 212 is used for correcting the deviation exceeding the allowable range.
In the cable tower construction equipment, the lifter 2 is arranged in an annular space formed by enclosing the cable tower 3, the tower crane 1 and the attachment structure so as to reduce the interference between the lifter 2 and the tower crane 1, while the position where the lifter 2 is arranged is not limited by the distance between the cable tower 3 and the tower crane 1, and the distance between the hoist 2 and the cable tower 3 can be reduced to shorten the wall-attached length of the guide rail 21 of the hoist 2, thereby reducing the safety risk, overcoming the problem that the bearing platform of the cable tower 3 or the basic fixing surface around the bearing platform is limited, compactly distributing the lifter 2, the tower crane 1 and the cable tower 3, being beneficial to fully utilizing the basic fixing surface and avoiding blocking a channel, meanwhile, the lifter 2 can be installed and detached by using the tower crane 1, so that the conflict between the lifter 2 and the tower crane 1 can be reduced.
In addition, by arranging the transition platform 5 between the inclined single-cage lifter 2001 and the vertical single-cage lifter 2002, the construction personnel can go up and down conveniently, so that the risk coefficient of the construction personnel when switching the two lifters 2 is reduced, and the construction efficiency is improved.
In addition, the method for completing the construction of the cable tower 3 by the cable tower construction equipment comprises the following steps:
firstly, foundation pre-embedding of a cable tower 3 and pouring of a main bearing platform of the cable tower 3 are required to be completed, foundation pre-embedding of a tower crane 1 is carried out on two sides, located on the cable tower 3, of the main bearing platform, then the cable tower 3 to be constructed is divided into 41 sections, when the sections of the cable tower 3 are divided, the bearing capacity of a buttress and a lower tower column 33 are required to be comprehensively considered, and meanwhile, the tower crane 1 is erected on the foundation pre-embedding of the tower crane 1 for the cable tower 3 to apply.
The construction of the cable tower can be carried out by matching with a template system, a constructor firstly installs a template on a main bearing platform, fixes the template and the main bearing platform by using foundation bolts, then pours concrete, removes the upper surface of the concrete of the section after the concrete is solidified, then lifts the template of the next section to the finished concrete section by adopting a tower crane 1, the constructor can carry out the reinforcement binding of the template and the finished concrete section template by setting up a ladder stand to move to the corresponding position, buries a specified template and then carries out the pouring of the concrete of the section.
After reaching cable tower 3 and reacing the take-up height, need to build lift 2 and attach wall structure 4 on cable tower 3, lift 2 can be convenient for the constructor pass through lift 2 removes corresponding cable tower 3 construction position, attaches wall structure 4 and can improve the stability of tower machine to lift 2 is located by cable tower 3, tower crane 1 and attach the annular structure that wall structure 4 encloses and close the formation, reducible lift 2 occupies to the channel.
According to the construction method of the cable tower 3 construction equipment, the tower column is divided into the plurality of sections, the sections are poured one by one, the tower crane 1, the lifter 2 and the template system are matched, reinforcing steel bars are bound, and pouring is carried out.
The foregoing is only a partial embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations should also be regarded as the protection scope of the present application.
