Description

Technical Field

[0001] This utility model belongs to the field of windproof technology, specifically relating to windproof cable locks for cranes. Background Technology

[0002] When cranes are in operation, they need to take a series of effective wind protection measures to ensure safe operation in windy weather. Existing wind protection measures for cranes include rail clamps and anchoring devices. Rail clamps prevent the crane from being blown away by the wind by clamping the crane rails, while anchoring devices fix the crane to the anchoring seat on the ground when it is not working to prevent it from being blown away by strong winds.

[0003] Existing windproof measures for cranes have certain limitations. They require high operational precision when windproofing cranes. For example, rail clamps need to slide along the rails until they are in contact with the bottom of the crane, or the crane needs to be moved to be in contact with the rail clamps. If there is a gap, it will affect the windproofing of the crane. Anchoring devices require the crane to be moved to the designated anchor point and the pin holes on the crane to be aligned with the pins on the anchoring device before the anchor rod is inserted. This operation requires even higher precision in the movement of the crane.

[0004] Therefore, a windproof cable lock for cranes is designed to solve the technical problem that the activation of windproof measures in the prior art requires a high degree of precision in the movement of the crane, resulting in a long time consumption.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] In a first aspect, embodiments of this disclosure provide a windproof cable lock for cranes, comprising:

[0008] The clamp sleeve, the top of which is connected to the outer wall of the crane;

[0011] The drive mechanism is adapted to drive the locking mechanism to close upon startup.

[0012] In one alternative embodiment, the locking mechanism includes:

[0013] At least two driven locking members, and each driven locking member has a windproof lug at its bottom end; wherein the top ends of each driven locking member are stacked inside the clamp sleeve; and

[0026] In one optional embodiment, a connecting sleeve is provided at the top end of the clamp sleeve; wherein

[0027] The connecting sleeve is connected to the crane via a connecting pin.

[0028] The beneficial effects of this utility model are that the windproof cable lock for the crane is equipped with a locking mechanism and a driving mechanism.

[0041] Research has revealed that existing windproofing measures for cranes have certain limitations. They require high operational precision when windproofing cranes. For example, rail clamps need to slide along the rails until they are in contact with the bottom of the crane, or the crane needs to be moved to be in contact with the rail clamps. If there is a gap, it will affect the windproofing of the crane. Anchoring devices require the crane to be moved to the designated anchor point and the pin holes on the crane to be aligned with the pins on the anchoring device before the anchor rod is inserted. This operation requires even higher precision in the movement of the crane.

[0042] Based on the above research, this disclosure provides a windproof cable lock for cranes. By providing a locking mechanism and a driving mechanism, when it is necessary to lock the crane, the driving mechanism drives the locking mechanism to close, so that each driven locking part on the locking mechanism closes to clamp and hook onto the locking base set on the ground. The operation is simple and does not require the crane to be moved to a precise position. It only requires the locking mechanism to be connected to the locking base.

[0043] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] This windproof cable includes: a clamp sleeve, the top of which is connected to the outer wall of the crane; a locking mechanism connected to the clamp sleeve, adapted to connect to a locking base set on the ground when closed to connect the crane to the locking base; and a drive mechanism disposed on the clamp sleeve and connected to the locking mechanism; wherein the drive mechanism is adapted to drive the locking mechanism to close when started.

[0045] The locking mechanism includes: at least two driven locking members, each driven locking member having a windproof lug at its bottom end; the top ends of each driven locking member are stacked inside the clamping sleeve; and a connecting shaft, which passes through the clamping sleeve and each driven locking member to connect each driven locking member to the clamping sleeve.

[0046] The drive mechanism includes: a servo motor, which is located inside the clamping sleeve; the output end of the servo motor is connected to at least two drive shafts; and each drive shaft is provided with a movable part.

[0047] The number of moving parts corresponds to the number of driven locking parts, and the top of each moving part is connected to the bottom of its corresponding drive shaft; and the bottom of each moving part is connected to the top of its corresponding driven locking part.

[0048] The locking base includes: a base body, which is set on the ground surface; and a windproof rod set on the base body; wherein each driven locking member, after being closed, has a windproof lug at its bottom end that hooks onto the windproof rod.

[0049] The top of the clamp sleeve is provided with a connecting sleeve; the connecting sleeve is connected to the crane by a connecting pin.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, when the operator detects a strong wind, the crane is moved to the vicinity of the base body 41, and the servo motor 20 is started. The output end of the servo motor 20 drives the drive shaft 21 to move, and the top end of the drive shaft 21 is connected to the output end of the servo motor 20 via a bearing (preferably, there are two drive shafts 21, two movable parts 210, and two connecting shafts 31). During the movement and deflection of the drive shaft 21, the corresponding movable part 210 is deflected. The top end of the movable part 210 is connected to the bottom end of the drive shaft 21 via a bearing, and the bottom end of the movable part 210 is fixed to the corresponding driven locking part 31. The two driven locking parts 31 are stacked and connected to the clamp sleeve 1 via a bearing using the connecting shaft 30. Therefore, as the movable part 210 deflects, the corresponding driven locking part 31 can be driven to deflect around the connecting shaft 30, thereby realizing closure and opening.

[0051] In some embodiments, such as Figure 3 and Figure 4 As shown, the windproof pull chain is in an inactive state at this time, meaning that the two driven locking members 31 are in the open state. Before a strong wind arrives, the servo motor 20 is started, and its output end moves upward, driving the two drive shafts 21 to move, which in turn drives the moving part 210 and the driven locking members 31 to deflect, causing the two driven locking members 31 to come closer together until they form a closed loop. Figure 4 In the state shown, the two driven locking parts 31 overlap, and the windproof lugs fixed at the bottom of the two driven locking parts 31 are hooked onto the windproof bar 40. By clamping and locking the windproof bar 40, the crane is connected to the base body 41 to resist strong winds.

[0052] In summary, by incorporating both a locking mechanism and a drive mechanism, when the crane needs to be locked, the drive mechanism drives the locking mechanism to close, causing the driven locking components on the locking mechanism to close and clamp onto the locking base on the ground. The operation is simple, allowing for deviations between the crane and the locking base, as long as the locking mechanism can connect to the locking base.
