Description

Technical Field

[0001] This application belongs to the field of crane technology, specifically relating to a rope-supporting device and a tower crane. Background Technology

[0002] Currently, medium and large tower cranes are gaining an increasingly larger market share. Due to the long jib and large hoisting wire rope of large tower cranes, the hoisting wire rope tends to sag under its own weight when unloaded, especially in large tower cranes with long jibs and thick hoisting wire ropes. During the tower crane's rotation, the sagping hoisting wire rope can easily snag on buildings or other obstacles below the crane.

[0003] Therefore, a rope support device needs to be installed on the crane boom to reduce the sag of the hoisting wire rope. However, the existing rope support device is installed below the crane boom, on the crane boom after the tower is erected, which makes the installation and removal of the rope support device difficult.

The first connecting plate is welded to the vertical beam, and the second connecting plate is bent from the upper end of the first connecting plate. The second connecting plate is detachably connected to the connecting horizontal plate.

[0007] In this embodiment, the second connecting plate and the connecting cross plate are detachably connected by a locking assembly, which includes a locking bolt and a locking nut. The shank of the locking bolt passes through the second connecting plate and the connecting cross plate in sequence and is threadedly connected to the locking nut.

[0008] In this embodiment, the locking bolt has a through pin hole at the end away from the second connecting plate, and the locking assembly also includes an anti-loosening pin for extending into the pin hole.

[0009] In this embodiment of the application, connecting seats are provided on both sides of the vertical beam.

[0010] In this embodiment of the application, the walking wheel body includes a roller, a shaft, a bearing, and a stop assembly. The roller is rotatably sleeved on the shaft through the bearing. The first end of the shaft extends out of the bearing and is provided with an axial stop portion extending radially. The axial stop portion abuts against the bearing end. The second end of the shaft passes through the mounting vertical plate, and the second end of the shaft is movably connected to the stop assembly, which is used to abut against the mounting vertical plate.

[0022] Explanation of reference numerals in the attached figures Detailed Implementation

[0023] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0024] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0025] The rope-supporting device and tower crane of this application are described below with reference to the accompanying drawings.

[0026] Please see Figure 1Taking a flat-head crane boom 300 as an example (not limited to flat-head crane boom 300), the working principle of the rope-supporting device 100 is explained. The rope-supporting device 100 is used to support the drooping lifting wire rope. The rope-supporting device 100 on the front side of the load trolley 200 is the first rope-supporting device 100, which can be placed in the middle of the crane boom 300. The rope-supporting device 100 on the rear side of the load trolley 200 is the second rope-supporting device 100, which can be placed at the base of the crane boom 300. The first rope-supporting device 100 and the second rope-supporting device 100 are connected by a connecting rope. When the load trolley 200 moves between the first rope-supporting device 100 and the second rope-supporting device 100, the first rope-supporting device 100 and the second rope-supporting device 100 are stationary, and the drooping lifting wire rope is supported by the first rope-supporting device 100. When the trolley 200 travels rapidly to the position of the first rope-supporting device 100, it will collide with the first rope-supporting device 100. The trolley 200 will then push the first rope-supporting device 100 forward along the boom 300. The first rope-supporting device 100 will then pull the second rope-supporting device 100 along the connecting rope. When the trolley 200 pushes the first rope-supporting device 100 to the end of the boom 300, the second rope-supporting device 100 is pulled to the middle of the boom 300, at which point the drooping hoisting wire rope is supported by the second rope-supporting device 100. By cooperating with the rope-supporting device 100, the trolley 200 can support the drooping hoisting wire rope, reducing its sag and preventing it from getting caught on buildings or other obstacles below the tower crane.

[0027] like Figures 2 to 5 As shown, this application provides a rope-supporting device 100, wherein the rope-supporting device 100 includes a rope-supporting bracket 10 and two walking wheel assemblies 20. The rope support 10 includes a crossbeam 11 for placement on the lower side of the boom 300 and two vertical beams 12 respectively disposed at both ends of the crossbeam 11. The top of the vertical beam 12 is provided with a connecting seat 13. The two vertical beams 12 are respectively disposed on opposite sides of the boom 300. Two traveling wheel assemblies 20 are respectively disposed one-to-one with the two vertical beams 12. The traveling wheel assembly 20 includes a traveling wheel bracket 21 and a traveling wheel body 22. The traveling wheel bracket 21 includes a mounting vertical plate 211 and a connecting horizontal plate 212 connected to each other. The mounting vertical plate 211 extends along the height direction. The connecting horizontal plate 212 bends and extends from the lower end of the mounting vertical plate 211. The traveling wheel body 22 is rotatably disposed on the mounting vertical plate 211 and is used to hang on the boom 300. The connecting horizontal plate 212 is placed on the connecting seat 13 and is detachably connected to the connecting seat 13.

[0028] A crossbeam 11 is positioned below the boom 300. Two vertical beams 12 are fixedly connected to both ends of the crossbeam 11 and are located on opposite sides of the boom 300. Each of the two vertical beams 12 has a corresponding traveling wheel assembly 20, which rolls relative to the boom 300. The traveling wheel bracket 21 includes an integrally bent mounting vertical plate 211 and a connecting horizontal plate 212. The mounting vertical plate 211 extends along the height direction and has a rotatably mounted traveling wheel 22. The traveling wheel 22 is mounted on the boom 300 and can roll into contact with the boom 300, allowing the rope-supporting device 100 to move smoothly on the boom 300. The connecting horizontal plate 212 is bent from the lower end of the mounting vertical plate 211 and rests on a connecting seat 13 at the top of the vertical beam 12.

[0029] The connecting horizontal plate 212 and the connecting seat 13 are detachably connected, making the installation of the rope-supporting device 100 more convenient. During installation, the crossbeam 11 is first placed under the boom 300, then the connecting seat 13 is positioned above the upper surface of the boom 300, and finally the connecting horizontal plate 212 and the connecting seat 13 are assembled, so that the traveling wheel 22 is mounted on the boom 300, thus enabling the rope-supporting device 100 to be installed on the boom 300. In this application, the assembly position is between the connecting horizontal plate 212 and the connecting seat 13, with the connecting seat 13 positioned above the upper surface of the boom 300. This position of the rope-supporting device 100 above the upper surface of the boom 300 makes it easier to install or remove it from the boom 300 after the tower is erected.

The second connecting plate 132 is detachably connected to the connecting horizontal plate 212.

[0031] The connecting seat 13 includes a first connecting plate 131 and a second connecting plate 132 connected in sequence. The first connecting plate 131 and the second connecting plate 132 are integrally bent parts, saving assembly steps and reducing assembly errors between the first connecting plate 131 and the second connecting plate 132. The first connecting plate 131 is welded to the vertical beam 12 to achieve a stable and reliable connection between the connecting seat 13 and the vertical beam 12. The second connecting plate 132 is bent from the upper end of the first connecting plate 131 in a direction away from the vertical beam 12. The second connecting plate 132 extends horizontally and is detachably connected to the connecting horizontal plate 212 to achieve a detachable connection between the connecting plate 131 and the connecting horizontal plate 212.

[0032] In the embodiments of this application, please refer to Figure 5 The second connecting plate 132 and the connecting horizontal plate 212 are detachably connected by a locking assembly 23. The locking assembly 23 includes a locking bolt 231 and a locking nut 232.

The second end 2222 of the rotating shaft 222 passes through the mounting vertical plate 211, and the second end 2222 of the rotating shaft 222 is movably connected to the stop assembly 224, which is used to abut against the mounting vertical plate 211.

[0038] Roller 221 is rotatably mounted on shaft 222 via bearing 223, making rotation of roller 221 easier and improving its smoothness and reliability, thus significantly increasing its efficiency and lifespan. The first end 2221 of shaft 222 extends out of bearing 223 and has an axial stop 2223 extending radially outward. The axial stop 2223 abuts against bearing 223, allowing the first end 2221 of shaft 222 to be fixed. The second end 2222 of shaft 222 passes through mounting plate and is movably connected to stop assembly 224, which abuts against mounting vertical plate 211 to fix the second end 2222 of shaft 222.

[0047] In the embodiments of this application, please refer to Figure 2 A reinforcing rod 14 is provided between the horizontal beam 11 and the vertical beam 12. By providing the reinforcing rod 14, the connection strength between the horizontal beam 11 and the vertical beam 12 is improved, thereby improving the structural strength of the rope-supporting device 100 and making the structural stability of the rope-supporting device 100 higher.

[0048] In the embodiments of this application, please refer to Figure 2 and Figure 8 Two rope rollers 40 are arranged at intervals in the middle of the crossbeam 11, and the two rope rollers 40 are respectively arranged to protrude towards the two sides of the crossbeam 11 to form a clearance space with the crossbeam 11.

[0049] By creating clearance space to avoid the wire rope breakage prevention device 201 on the load trolley 200, the rope roller 40 can be prevented from interfering with the load trolley 200, making the use of the rope roller 40 and the load trolley 200 more stable and reliable.

[0050] Based on this, please refer to Figure 2 The rope roller 40 includes a roller 42 and two ear plates 41.
