Description

Tower Crane System

technical field

The utility model relates to the field of construction machinery, in particular to a tower crane system.

Background technique

When the height of the tower crane exceeds its maximum independent height, before further raising the height of the tower crane, in order to avoid the collapse of the tower crane, the construction personnel will connect the tower crane to the building structure through the attachment rod. But removing the attachment pole of a tower crane is a dangerous operation. At present, the removal of the attachment rod of most tower cranes relies on the tower crane itself as an auxiliary lifting device to remove the attachment rod. Traditional dismantling methods have the following drawbacks:

(1) The rotation of the upper part of the tower crane is limited. Before removing the attachment rod, the tower crane needs to lower itself below the height of the attached building structure, thus limiting the slewing of the upper part of the tower crane.

(2) When the attachment rod is long, it is difficult to disassemble and the safety risk is high. When the tower crane itself dismantles the attachment rod, it is necessary to pull the attachment rod obliquely. However, when the attachment rod is long, the self-weight of the attachment rod is large, or one end of the attachment rod protrudes deeply into the building structure, it becomes particularly difficult to disassemble the attachment rod only by the tower crane itself, and the safety risk is great.

(3) May damage the glass curtain wall. When the tower crane removes the attachment rod deep into the super high building structure, the glass curtain wall at the attachment point on one side of the building structure is usually installed, and only a narrow opening is reserved at the attachment point. It is difficult to ensure that the curtain wall glass will not be damaged when the attachment rod is moved out of the hole if only the tower crane itself is used to remove the attachment rod.

The third hoist 20 is preferably an inverted chain hoist.

The first method of removing the attachment rod will be described in detail below with reference to FIGS. 1 to 12 .

As shown in FIG. 1 , one end of the attachment rod is connected to the building structure, and the other end is connected to a standard section 104 of the tower crane body 10 (specifically, the attachment rod is connected to a standard section through an attachment frame).

The first step, as shown in FIG. 4 to FIG. 5 , lowers the wire rope of the first hoist 123 to the second operation platform 16 , then connects the wire rope to the attachment rod, and then releases the connection between the attachment rod and the standard section 104 .

In addition, when the tower crane system is provided with the third hoist 20, the reverse chain of the third hoist 20 can be lowered and connected to the attachment rod first, and then the wire rope of the first hoist 123 can be connected to the attachment rod, Then, the connection between the third hoist 20 and the attachment rod is released. During the process of disconnecting the attachment rod from the standard section 104, the reverse chain of the third hoist 20 can prevent the attachment rod from swinging.

The second step, as shown in Figures 4 to 5, is to lower the wire rope of the second hoist 18, then connect its wire rope to the attachment rod, and then release the attachment rod from the building structure.

The third step, as shown in FIG. 6 , lifts the wire rope of the first hoist 123 and lowers the wire rope of the second hoist 18 at the same time, so that the attachment rod is slowly removed from the building structure. As shown in Figure 7, when the attachment rod is completely removed from the building structure, the first hoist 123 stops lifting. As shown in Figures 7 to 8, the wire rope of the second hoist 18 is then continued to be lowered until the attachment rod reaches a vertical posture. The connection between the wire rope of the second hoist 18 and the attachment rod is then released. Of course, the construction personnel can release the connection between the attachment rod and the second hoist 18 on the second operating platform 16 .

In the fourth step, the attachment rod is continued to be pulled up by the first hoist 123 until the attachment rod reaches the first operation platform 14 . As shown in FIG. 9 to FIG. 10 , the first hoist 123 is then controlled to move in a direction close to the hook. As shown in Figure 11, the slings reserved on the attachment rods are then connected (on the third operating platform 22) to the hooks. At the same time, a first cable wind rope can also be tied on the attachment rod (the first cable wind rope can prevent the attachment rod from shaking during the hoisting and pulling process). The hook lifts the attachment rod until the wire rope of the first hoist 123 is loosened, and then releases the connection between the wire rope of the first hoist 123 and the attachment rod. As shown in Figure 12, then the hook continues to drive the attachment rod to move, and at the same time, the first cable wind rope is slowly loosened, so that the attachment rod gradually turns from the inclined state to the vertical state (because it is difficult for the first hoist 123 to just move to the position of the hook directly below, so when the attachment bar is attached to the hook, the attachment bar is in a tilted attitude). When the attachment rod is fully turned to the vertical position, the first cable wind rope is fully relaxed. Then, the attachment rod is hoisted to the ground by the tower crane body 10, so as to complete the disassembly of the entire attachment rod.

The second method of removing the attachment rod is described in detail below.

The first to third steps are the same as the first dismantling method and will not be repeated.

In the fourth step, the first hoist 123 continues to pull up the attachment rod until the attachment rod reaches the third operating platform 22, and then the first hoist 123 is controlled to move toward the hook. Then (on the third operating platform 22) the slings reserved on the attachment rods are connected to the hooks. At the same time, a third cable wind rope can be tied on the attachment rod (the third cable wind rope can prevent the attachment rod from shaking during the hoisting and pulling process). The hook lifts the attachment rod until the wire rope of the first hoist 123 is loosened, and then releases the connection between the wire rope of the first hoist 123 and the attachment rod. Then the hook continues to drive the attachment rod to move, and at the same time slowly loosen the third cable wind rope, so that the attachment rod gradually turns from the inclined state to the vertical state (because it is difficult for the first hoist 123 to reach just below the hook, the attachment rod is connected When reaching the hook, the attachment bar is slightly inclined). When the attachment rod is completely turned into a vertical posture, the third cable wind rope is completely loosened, and then the attachment rod is hoisted to the ground through the tower crane body 10, so as to complete the disassembly of the entire attachment rod.

The third method of removing the attachment rod is described in detail below.

The first step is to lower the wire rope of the first hoist 123 to the second operating platform 16 , then connect the wire rope to the attachment rod, and then release the connection between the attachment rod and the standard section 104 .

In addition, when the tower crane system is provided with the third hoist 20, the reverse chain of the third hoist 20 can be lowered and connected to the attachment rod first, and then the wire rope of the first hoist 123 can be connected to the attachment rod, Then, the connection between the third hoist 20 and the attachment rod is released.

The second step is to lower the wire rope of the second hoist 18, then connect its wire rope to the attachment rod, and then release the attachment rod from the building structure.

In the third step, the wire rope of the first hoist 123 is lifted, and the wire rope of the second hoist 18 is lowered at the same time, so that the attachment rod is slowly removed from the building structure. When the attachment bar is completely removed from the building structure, the first hoist 123 stops lifting. Then continue to lower the wire rope of the second hoist 18 until the attachment bar reaches a vertical posture. The connection between the wire rope of the second hoist 18 and the attachment rod is then released. Of course, the construction personnel can release the connection between the attachment rod and the second hoist 18 on the second operating platform 16 .

The fourth step is to control the first hoist 123 to move toward the direction close to the hook. Then (on the third operating platform 22) connect the sling reserved on the attachment rod to the hook, and at the same time, a second cable wind rope can be attached to the attachment rod (the second cable wind rope can prevent the attachment rod from being pulled shaking during the process). The hook lifts the attachment rod until the wire rope of the first hoist 123 is loosened, and then releases the connection between the wire rope of the first hoist 123 and the attachment rod. Then, the hook continues to drive the attachment rod to move, and at the same time, the second cable wind rope is slowly loosened, so that the attachment rod gradually turns from the inclined state to the vertical state. When the attachment rod is completely turned into a vertical posture, the second cable wind rope is completely loosened, and then the attachment rod is hoisted to the ground through the tower crane body 10 to complete the disassembly of the entire attachment rod.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, but not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions depart from the spirit of the technical solutions of the embodiments of the present invention and range.
