Description

Technical Field

[0001] The utility model relates to the field of floating crane installation structures, in particular to a truss type boom roller auxiliary installation tool. Background Art

[0002] During the installation of the luffing winding system of the floating crane, the luffing pulley block at the head of the boom and the luffing pulley block at the head of the A-frame were too long, causing the luffing wire rope to hang on the boom, wearing out the boom structure. At the same time, in order to facilitate construction workers to walk back and forth on the top of the boom to check for interference, deflection and other problems during rope threading, it is necessary to lay a full scaffold on the top of the boom. After the rope threading is completed, the removal of the scaffolding involves a lot of high-altitude operations, which poses a major safety hazard. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a truss-type boom roller auxiliary installation tooling to solve the problems in the prior art that the variable-length wire rope is easily caused to swing on the boom, which wears the boom structure and involves a large amount of high-altitude operations when dismantling the scaffolding after the rope is threaded, posing a major safety hazard.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a truss-type boom roller auxiliary installation tool, the innovation of which is: comprising a support frame, a roller and a hoop;

[0005] The arm is arranged transversely;

[0006] The clamp is installed on the arm;

[0007] The support frame is longitudinally arranged on the top of the arm frame and connected to the hoop, and the support frame is composed of a plurality of seamless steel pipes;

[0008] The rollers are installed at both longitudinal sides of the top of the support frame.

[0009] Furthermore, a rubber pad is laid between the clamp and the arm to avoid wearing the paint of the arm.

[0010] Furthermore, the support frame includes a transverse tube, a first vertical tube and a second vertical tube, and the first vertical tube and the second vertical tube are arranged on both sides of the bottom end of the transverse tube, and a clamp is fixed to the bottom end of each of the first vertical tube and the second vertical tube, and is detachably connected to the arm through the clamp.

[0011] Furthermore, the support frame also includes an inclined straight pipe arranged close to the second vertical pipe, and the top of the inclined straight pipe is connected to the horizontal pipe, and the bottom of the inclined straight pipe is also connected to the arm through a clamp.

[0012] Furthermore, the distance between the adjacent closer ends of the second vertical pipe and the horizontal pipe is 500 mm, and the space is a scaffolding channel, and the width of the scaffolding channel is greater than the distance between the adjacent closer ends of the first vertical pipe and the horizontal pipe. By laying a scaffolding channel with a width of about 500 mm between the rollers, it is convenient for construction workers to check interference, deflection and other problems when threading the rope.

[0013] The advantages of the utility model are:

[0014] 1) The utility model has a simple overall structure and is easy to manufacture. When installing the luffing wire rope, the wire rope is dragged by the roller, which can effectively prevent the luffing wire rope from swaying, avoid wearing the boom structure, greatly reduce the erection of scaffolding, and shorten the project cycle;

[0015] 2) The support frame of the utility model is installed on the arm frame in the form of a hoop, which is firmly installed and easy to disassemble, and can also reduce the laying of a large number of scaffolds and high-altitude operations;

[0016] 3) The utility model can be used continuously in all subsequent crane projects after simple modification according to the boom structure of different projects, and has strong practicality;

[0017] 4) By laying a scaffolding channel with a width of about 500mm between the rollers, it is convenient for construction workers to check interference, deflection and other problems when threading the rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 4 A truss-type boom roller auxiliary installation tool shown includes a support frame 1, a roller 2 and a hoop 3;

[0024] The arm 4 is arranged transversely, and includes a thicker first connecting rod 41 and a thinner second connecting rod 42;

[0025] The clamp 3 is detachably mounted on the arm 4 by bolts, and includes a large clamp 31 mounted on the first connecting rod 41 and a small clamp 32 mounted on the second connecting rod 42 .

[0026] A rubber pad 5 is laid between the hoop 3 and the arm 4 to avoid wearing the paint of the arm 4.

[0027] The support frame 1 is longitudinally arranged on the top of the arm frame 4 and connected to the hoop 3, and the support frame 1 is composed of a plurality of seamless steel pipes;

The first vertical tube 12 is longer and is connected to the second connecting rod 42 of the arm 4 through a small clamp 32. The second vertical tube 13 is shorter and is connected to the second connecting rod 42 of the arm 4 through a large clamp 31, so that the transverse tube 11 remains in a horizontal state.

[0029] The support frame 1 further includes an inclined straight pipe 14 disposed near the second vertical pipe 13 , and the top of the inclined straight pipe 14 is connected to the horizontal pipe 11 , and the bottom of the inclined straight pipe 14 is also connected to the arm frame 4 via a clamp 3 .
