Description

Technical Field

[0001] The utility model relates to the technical field of anchoring, in particular to a heavy-weight anchoring device. Background Art

[0002] Cranes operating outdoors must be secured with anchors when not in use to prevent them from being blown away and tipping over in strong winds. Anchors are simple, safe, and reliable. They typically use a pin-type structure. Lifting the anchor shaft allows the crane to operate normally. After the crane stops operating, insert the anchor shaft into the anchor seat to anchor the crane.

[0003] Because the anchor shaft of the anchoring device needs to be manually raised and lowered, its weight is generally limited to 20kg, otherwise it would be impossible for an average person to lift it. However, some large cranes cannot meet the 20kg anchor shaft requirement, and overweight anchor shafts cannot be directly lifted manually. Therefore, a heavy-duty anchoring device has been designed to make it easy for ordinary people to lift the anchor shaft. The convenient operation ensures the safety of large outdoor cranes.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Please refer to Figures 1 to 4 , an embodiment of the utility model provides a heavy-weight anchoring device, comprising:

[0037] The bracket 1 has a vertical sleeve 11 fixedly provided at the bottom end of one side;

[0038] An anchoring shaft 2 slidably passes through the sleeve 11;

[0039] The lever drive assembly 3 is provided on one side of the bracket 1 and above the anchor shaft 2. It is in transmission connection with the anchor shaft 2 and is used to drive the anchor shaft 2 to move up and down along the sleeve 11.

[0040] A fixing assembly 4 is provided on the bracket 1 and is used to fix the raised anchor shaft 2;

[0041] The anchoring seat 5 is fixedly arranged on the ground corresponding to the anchoring shaft 2 , and an anchor pit is provided on the top of the anchoring seat 5 .

[0042] In this embodiment, when the large outdoor crane is not working, the anchor shaft 2 is inserted into the anchor pit on the top of the anchor seat 5, forming an anchor protection for the crane; before starting work, the lever driving component 3 is first used to drive the anchor shaft 2 to move upward along the sleeve 11, so that the anchor shaft 2 is separated from the anchor seat 5; after the anchor shaft 2 is lifted, it is fixed by the fixing component 4, and then the crane can work normally.

[0043] After the crane stops working, it is controlled to move on the track so that the anchor shaft 2 is aligned with the anchor pit. At this time, the fixing component 2 is removed to unlock the fixation of the anchor shaft 2, and the anchor shaft 2 is lowered through the lever driving component 3 so that the anchor shaft 2 is inserted into the anchor pit to complete the anchoring operation of the crane.

[0044] The anchoring device of the present application allows ordinary people to easily lift and lower the anchoring shaft 2 through the lever driving component 3. The lifted anchoring shaft 2 is fixed by the fixing component 4, which is easy to operate and ensures the safety of large outdoor cranes.

[0045] In a preferred embodiment, if Figure 4 As shown, the bracket 1 is fixedly arranged at the bottom of the lower crossbeam 6 of the crane, and the bottom of the crane is anchored by the anchoring device of the present application, which has high safety.

[0046] In a preferred embodiment, if Figure 1 and Figure 3 As shown, the lever drive assembly 3 includes a turntable 31, which is arranged on one side above the anchor shaft 2 and is rotatably connected to the bracket 1 through a first rotating shaft. A winding groove is provided on the turntable 31, and a traction rope 32 is provided in the winding groove. One end of the traction rope 32 is fixedly connected to the turntable 31, and the other end is fixedly connected to the top of the anchor shaft 2 in the vertical direction. A driving rod 33 is fixedly connected to one side of the turntable 31.

[0047] In this embodiment, the turntable 31 can be retracted or released by rotating the driving rod 33, thereby driving the anchor shaft 2 to move up and down along the sleeve 11 through the traction rope 32, thereby completing the anchoring or unanchoring operation. The lever drive assembly 3 uses the lever principle to greatly reduce the force required to move the anchor shaft 2, so that ordinary people can easily complete the operation of the heavy-weight anchoring device.

[0048] In a preferred embodiment, if Figure 1 and Figure 3 As shown, arc-shaped stoppers 34 are symmetrically positioned on either side of the upper portion of the turntable 31. A winding groove is formed between the two stoppers 34 on the outer side of the turntable 31. A single section of the winding groove is sufficient to lift the anchor shaft 2, eliminating the need for a full circle around the outer circumference of the turntable 31, thus simplifying fabrication. The winding groove limits the position of the traction rope 32, allowing it to be retracted or released along the annular surface of the turntable 31.

[0049] In a preferred embodiment, if Figure 1 and Figure 3 As shown, a limiting assembly 7 is provided above the turntable 31; the limiting assembly 7 includes a pawl 71, which is rotatably connected to the bracket 1 through a second rotating shaft, a connecting rod 72 is fixedly provided on one side of the pawl 71, and a plurality of ratchet grooves 35 adapted to the pawl 71 are provided on the outer side of the limiting plate 34.

[0050] In this embodiment, when the turntable 31 is rotated by the driving rod 33 to retract the traction rope 32, the pawl 71 cooperates with the ratchet groove 35 so that the turntable 31 will not rotate back after the driving rod 33 is released. After the anchor shaft 2 is lifted into place, the worker can release the driving rod 33 and fix the anchor shaft 2 with both hands, thereby improving the convenience of the fixing operation.

[0051] After completing the fixation of the anchor shaft 2, control the turntable 31 to rotate a smaller angle. At this time, the pawl 71 can be driven to rotate upward through the connecting rod 72 and disengage from the ratchet groove 35. At this time, remove the fixing component 4, and then slowly rotate the turntable 31 to lower the anchor shaft 2 until the anchor shaft 2 is inserted into the anchor pit, completing the anchoring of the anchor shaft 2. The operation is convenient.

[0052] In a preferred embodiment, the traction rope 32 is a steel wire rope, which has high structural strength and long service life.

[0053] In a preferred embodiment, if Figure 1 and Figure 2 As shown, a connecting plate 21 is fixedly provided on the top end of the anchor shaft 2, and the traction rope 32 is fixedly connected to the anchor shaft 2 through the connecting plate 21, and the connection is convenient and stable.

[0054] In a preferred embodiment, if Figure 1 and Figure 2 As shown, the fixing assembly 4 includes a fixing pin 41, and a pin hole is opened on one side of the anchor shaft 2 corresponding to the fixing pin 41. After the anchor shaft 2 is lifted, the fixing pin 41 is inserted into the pin hole to complete the fixation of the anchor shaft 2. The operation is convenient and the fixation is stable.

[0055] In a preferred embodiment, if Figure 1 and Figure 2As shown, one end of the fixing pin 41 is fixedly connected to an iron chain 42, and the other end of the iron chain 42 is fixedly connected to a buckle 43. The buckle 43 is detachably connected to the bracket 1, avoiding the problem of the fixing pin 41 being easily lost when placed arbitrarily when not in use.

[0056] In a preferred embodiment, the anchor seat 5 is pre-buried on the top of the concrete foundation, and the concrete foundation is buried underground, thereby ensuring the structural strength of the anchor seat 5 .
