Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a device for introducing standard sections. Background Technology

[0002] Tower cranes, also known as tower hoists, 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] Currently, the standard section is the core load-bearing unit of the tower crane, directly affecting the overall structural stability and construction safety. The introduction of standard sections typically involves using an introduction trolley, which is hoisted onto the introduction beam. The standard section to be introduced is then suspended on the trolley, and operators pull the standard section into the jacking frame.

[0004] However, manual pulling is time-consuming and laborious, and poses certain safety hazards. In addition, the standard section is usually suspended at a single point on the trolley, and the standard section can still rotate relative to the trolley after being suspended. As a result, the attitude and direction of the standard section are difficult to control during the pulling process, making the operation difficult. Utility Model Content

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] See Figures 1-3 The diagram shows a schematic representation of a device for introducing a standard section according to an embodiment of the present invention. The device includes a rotating base assembly 100, an introduction beam 200, and an introduction trolley assembly 300. The introduction beam 200 is mounted on the rotating base assembly 100, and the introduction trolley assembly 300 is mounted on the introduction beam 200. The introduction trolley assembly 300 is movable along the introduction beam 200 to move the standard section suspended on the introduction trolley assembly 300 into the lifting frame.

[0018] See details Figure 1 The rotating base assembly 100 includes a frame 110, a turntable bearing 120 connected to the frame 110, and a rotating frame 130 connected to the turntable bearing 120; the lead beam 200 is connected to the rotating frame 130; the rotating frame 130 can drive the lead beam 200 to rotate relative to the frame 110.

[0019] See Figure 2 and Figure 3 The trolley assembly 300 includes a trolley 310 and active travel wheels 311 and passive travel wheels 312 mounted on the trolley 310. Both the active travel wheels 311 and passive travel wheels 312 are engaged with the introduction beam 200. A drive device 313 is mounted on the trolley 310 and is connected to the active travel wheels 311. A chain 314 for connecting with a standard section is mounted on the trolley 310.

[0020] The aforementioned device for introducing standard sections includes a rotating base assembly 100. The rotating frame 130 on the rotating base assembly 100 can drive the introducing beam 200 to rotate at a certain angle (small angle), thereby adjusting the forward direction of the introducing trolley assembly 300 and further adjusting the position of the standard section. The drive device 313 can drive the active walking wheel 311 to rotate, causing the trolley 310 to reciprocate on the introducing beam 200, thereby realizing the introduction of the standard section suspended under the trolley 310. The controllability of the introduction process is improved, which is conducive to improving work efficiency.

[0021] Specifically, in one embodiment, four chains 314 are provided, and four rectangularly distributed connecting holes 315 are respectively provided at the bottom of the trolley 310, with one chain 314 connected to each connecting hole 315. It should be noted that in the prior art, a lifting ring is usually set at the center of the bottom of the trolley 310, and one end of multiple chains is connected to the same lifting ring, while the other ends of multiple chains are respectively connected to the four corners of the standard section. Although this can adjust the position of the standard section, the degree and direction of adjustment are uncontrollable. During the process of the standard section moving into the lifting frame, it is easy to bump into the standard section, which can also lead to low work efficiency. In this embodiment, each chain 314 has an independent connecting hole position. During the movement, the standard section will not undergo large-scale uncontrollable rotation. When the position adjustment is required during the process of the standard section entering the lifting frame, the guide beam 200 can be rotated by the rotating frame 130 to adjust the angle of the standard section suspended on the guide beam 200. This process makes the angle adjustment controllable, reduces the possibility of the standard section bumping into the standard section, is safer, and can also improve work efficiency to a certain extent.

[0022] like Figure 1 As shown, further, in one embodiment, to enhance the stability of the guide beam 200, the frame 110 is provided with a first connecting ear 111, on which a first C-shaped connector 112 is provided. The guide beam 200 is provided with a second connecting ear 210, on which a second C-shaped connector 211 is provided. One end of the connecting rod 400 is axially connected to the first C-shaped connector 112, and the other end of the connecting rod 400 is axially connected to the second C-shaped connector 211. With this configuration, the connecting rod 400 acts as an adjustable reinforcing rib between the guide beam 200 and the frame 110. Since the connecting rod 400 can rotate a certain angle relative to the first C-shaped connector 112 and the second C-shaped connector 211, it can both strengthen the connection and not affect the small-angle adjustment of the guide beam 200. Precisely because the angle is small, the guide beam 200 will not interfere with the four supports 113 provided at the bottom of the frame 110.

[0023] In one embodiment, a hollow cavity 140 is provided in the middle of the frame 110, and a turntable bearing 120 is provided in the hollow cavity 140. A rotating frame 130 is installed on the inner side of the turntable bearing 120, and an introduction beam 200 is fixed to the bottom of the rotating frame 130. The operator can control the rotating frame 130 to rotate relative to the frame 110, thereby driving the introduction beam 200 at the bottom of the rotating frame 130 to rotate. It should be noted that, under normal working conditions, only a small angle needs to be rotated to achieve the adjustment of the standard section position.

[0024] In one embodiment, the drive device 313 includes a variable frequency motor 3131 and a reducer 3132 connected to the variable frequency motor 3131. The output shaft of the reducer 3132 is connected to the drive wheel 311. Specifically, the variable frequency motor 3131 is mounted on the trolley 310, and the output shaft of the variable frequency motor 3131 is connected to the reducer 3132. The reducer 3132 plays the role of matching the speed and transmitting torque between the variable frequency motor 3131 and the working machine or actuator, thereby driving the drive wheel 311 to rotate. The drive wheel 311 drives the trolley 310 and the passive wheel 312 to move along the guide beam 200 on the guide beam 200, thereby driving the standard section of the lower suspension to move.

[0025] In one embodiment, the bottom of the frame 110 is provided with four support legs 113, which helps to improve the stability of the rotating base assembly 100.

[0026] See also Figure 1 and Figure 3 In one embodiment, a groove 220 is provided in the length direction of the lead beam 200, and the active walking wheel 311 and the passive walking wheel 312 are disposed inside the groove 220.

[0027] In one embodiment, the introduced beam 200 is configured as an I-beam. Grooves 220 are provided on both sides of the I-beam. Two active wheels 311 and one passive wheel 312 are housed within the groove 220 on the same side. The structure on the other side is symmetrical, as shown below. Figure 3 As shown, the trolley 310 is attached to the guide beam 200 by wheels on both sides and can move along the guide beam 200 under the drive of the drive device 313.
