Description

Technical Field

[0001] This utility model belongs to the field of tower crane installation technology, specifically an auxiliary tool for installing the boom tie rod of a tower crane. Background Technology

[0002] Tower cranes, also known as tower hoists, originated in Western Europe. They are rotating cranes with their booms mounted on the upper part of a tall tower. They offer a large working space and are mainly used for the vertical and horizontal transport of materials and the installation of building components in construction projects.

[0003] When installing a tower crane, especially after the boom is installed and the tie rods (tib rod pins) are installed, the trolley cannot be used. This forces installers to walk on the boom of the tower crane to install the pins at the tie rod position, and to travel from the tower body to the tie rod installation position. This poses a great safety hazard, and there have been many incidents of installers falling off the boom during installation.

[0004] To address this, we propose an auxiliary tool for installing the boom tie rod of a tower crane. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an auxiliary tool for installing the boom tie rod of a tower crane, which has the advantage of greatly ensuring the safety of installation personnel when they pass on the boom during tower crane installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for installing the boom tie rod of a tower crane, including a base, a tower body detachably mounted on the top of the base, a boom detachably mounted on the left top of the tower body, a fixed frame engaged on the left top of the boom, a first fixed column fixedly mounted on the top of the fixed frame, a lifting ring fixedly mounted on the top of the first fixed column, and a safety cable installed inside the lifting ring.

[0007] Preferably, a bolt is detachably provided at the bottom right side of the fixed frame, and the bolt passes through the right side of the fixed frame. A nut is provided at the upper part of the bolt in a spiral rotation, and the bottom end of the nut is fitted with the top right side of the fixed frame.

[0008] Preferably, a second fixing column is fixedly provided at the top middle part of the lifting arm, and a lifting ring is fixedly provided at the top of the second fixing column.

[0009] Preferably, a third fixing column is fixedly provided at the top right side of the lifting boom, and a lifting ring is fixedly provided at the top of the third fixing column.

[0010] Preferably, the outer middle part of the safety cable passes through the top eyelet of the second fixed post and is detachably connected to the top eyelet of the third fixed post.

[0011] Preferably, a counterweight arm is detachably provided at the top right side of the tower body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a fixed frame, can be fixed to the lifting arm on the ground with bolts and nuts. During the installation of the tower crane, it can greatly ensure the safety of the installation personnel. Moreover, this device is easy to install, simple to manufacture, and inexpensive after the tower crane boom is assembled, and has great practical significance. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, this utility model provides an auxiliary tool for installing the boom tie rod of a tower crane, including a base 1, a tower body 2 detachably mounted on the top of the base 1, a boom 3 detachably mounted on the left top of the tower body 2, a fixed frame 8 engaged on the left top of the boom 3, a first fixed column 4 fixedly mounted on the top of the fixed frame 8, a lifting ring fixedly mounted on the top of the first fixed column 4, and a safety cable 5 installed inside the lifting ring for the protection of the installation personnel.

[0020] Specifically, a bolt 9 is detachably provided at the bottom right side of the fixed frame 8, and the bolt 9 passes through the right side of the fixed frame 8. A nut 10 is provided at the upper part of the bolt 9 in a spiral rotation, and the bottom end of the nut 10 fits against the top right side of the fixed frame 8. The bolt 9 and the nut 10 limit and fix the fixed frame 8.

[0021] Furthermore, a second fixing post 6 is fixedly provided at the top of the middle part of the lifting boom 3, and a lifting ring is fixedly provided at the top of the second fixing post 6. The second fixing post 6 is used to limit the safety cable 5.

[0022] Furthermore, a third fixing post 7 is fixedly installed at the top right side of the lifting boom 3, and a lifting ring is fixedly installed at the top of the third fixing post 7. The third fixing post 7 is used to fix the other end of the safety cable 5.
