Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and specifically to a tower crane hoisting auxiliary device. Background Technology

[0002] Tower cranes are rotating cranes with their booms mounted on the upper part of a tall tower. They have a large working space and are mainly used for the vertical and horizontal transport of materials and the installation of building components in building construction.

[0003] When using a tower crane for hoisting, ropes are generally needed to secure the items. In this case, the ropes need to be passed through the bottom of the items. However, the bottom of the items is usually close to the ground with few gaps, or the items are moved to the ground below the tower crane by a forklift. The pallet beam is located between the ground and the items, and the gap at the bottom of the pallet beam is small. In both cases, it is not easy to pass the ropes through the bottom of the items to secure them.

[0004] To address the aforementioned problems, this application proposes a tower crane hoisting auxiliary device. Utility Model Content

The first roller 207 and... The second rotating roller 211 is connected to the first transmission belt 212. According to the above scheme, specifically, by moving the item between the two sets of auxiliary structures 2, and then pressing the surface of the item with the friction roller 209, the first motor 205 is started, which drives the rotation of the first shaft 206. The rotation of the first shaft 206 drives the rotation of the first rotating roller 207. The rotation of the first rotating roller 207 drives the transmission of the first transmission belt 212. The transmission of the first transmission belt 212 drives the rotation of the second rotating roller 211. The rotation of the second rotating roller 211 drives the rotation of the rotating rod 210. The rotation of the rotating rod 210 drives the rotation of the friction roller 209, thereby lifting the item and making the bottom of the item have enough space for the workers to pass the rope through the bottom of the item.

[0029] Reference Figure 2 A second motor 213 is installed at one end of the slide rail 203. A first threaded rod 214 is installed at the output end of the second motor 213 through the slide rail 203. The outer side of the first threaded rod 214 is threadedly connected to the slider 204. By starting the second motor 213, the first threaded rod 214 is rotated, which in turn moves the slider 204. The movement of the slider 204 causes the friction roller 209 to press the surface of the object.

[0030] Reference Figure 3 A drain outlet 215 is provided on the slide rail 203. The drain outlet 215 is used to drain the rainwater collected in the slide rail 203 during rainy days.

[0031] Reference Figure 1 and Figure 4The connecting frame 1 is equipped with an adjustment structure 3, which includes a third motor 301, a support tube 306 mounted on one of the connecting frames 1, and a threaded tube 308 mounted on the other connecting frame 1. A second threaded rod 307 is rotatably connected inside the support tube 306, and the outer side of the second threaded rod 307 is threadedly connected to the inner side of the threaded tube 308. A second shaft 302 is mounted on the output end of the third motor 301. A third roller 303 is mounted on one end of the second shaft 302, and a fourth roller 305 is mounted on one end of the second threaded rod 307. A second transmission belt 304 drives the third roller 303 and the fourth roller 305 together. One of the connecting frames 1 is equipped with a support frame 309, and a third motor 301 is mounted on the support frame 309. According to the above technical solution, specifically, by starting the third motor 301, it drives the second shaft 302 to rotate. The rotation of the second shaft 302 drives the rotation of the third roller 303. The rotation of the third roller 303 drives the transmission of the second transmission belt 304. The transmission of the second transmission belt 304 drives the rotation of the fourth roller 305. The rotation of the fourth roller 305 drives the rotation of the second threaded rod 307, thereby driving one of the connecting frames 1 to move, thus achieving the ability to handle items of different sizes.

[0032] It should be noted that a smooth steel plate can be laid on the bottom of the connecting frame 1 with the threaded pipe 308 installed, which facilitates the movement of the connecting frame 1.

[0033] Working principle:

[0034] This tower crane lifting auxiliary device works by moving the object between two sets of auxiliary structures 2, then pressing the surface of the object with friction roller 209. By starting the first motor 205, it drives the rotation of the first shaft 206, which in turn drives the rotation of the first rotating roller 207. The rotation of the first rotating roller 207 drives the first transmission belt 212, which in turn drives the rotation of the second rotating roller 211. The rotation of the second rotating roller 211 drives the rotation of the rotating rod 210, which in turn drives the rotation of the friction roller 209. This lifts the object, providing sufficient space at the bottom for workers to pass ropes through it.

[0035] The tower crane hoisting auxiliary device, by starting the third motor 301, drives the rotation of the second shaft 302, which in turn drives the rotation of the third roller 303, which in turn drives the transmission of the second drive belt 304, which in turn drives the rotation of the fourth roller 305, which in turn drives the rotation of the second threaded rod 307, thereby moving one of the connecting frames 1, thus enabling it to handle items of different sizes.
