Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifting equipment, and in particular relates to a horizontal lifting equipment. Background Art
[0002] Lifting equipment is a commonly used lifting equipment, generally used for moving and transporting large workpieces during the production and processing process. For example, during the production and processing of wind turbine nacelles, horizontal lifting equipment is needed to lift larger workpieces such as wind turbine nacelles for moving and transporting.
[0003] A clamp hook is a relatively common horizontal lifting device. When working, the clamp walls on both sides will automatically extend and retract under electric control, and the hook feet at the bottom of the clamp wall can be extended into the wind turbine nacelle from both sides to lift it for moving and transporting. However, there are some problems with the existing horizontal lifting equipment of this type during use. The lowering height of the clamp hook is usually generally judged and controlled by the naked eye by the staff. When using it, it is very likely that the clamp hook will fall and hit the workpiece due to the negligence of the staff, causing damage to the workpiece. In addition, during use, the clamp walls on both sides of the clamp hook may also directly contact and squeeze the side ends of the workpiece such as the wind turbine nacelle, causing wear on the workpiece, and the overall use is relatively inconvenient. Therefore, it is necessary to propose an improvement measure to solve the above technical problems. Utility Model Content

Example
[0023] Reference Figure 1-3 A horizontal lifting device of this embodiment includes a clamp-shaped hook 1. The clamp-shaped hook 1 can directly adopt an existing clamp-shaped hook device, which can also be called an electric horizontal coiling hook. Clamp arms 11 that can be electrically controlled to extend and retract are correspondingly provided on both sides of the clamp-shaped hook 1, and hook feet 12 are correspondingly provided at the bottom of the clamp arm 11.
[0024] The hook foot 12 is detachably mounted with a rubber sleeve 6. The shape of the rubber sleeve 6 matches that of the hook foot 12. A slot 601 with an opening on one side is correspondingly provided in the rubber sleeve 6. The shape and size of the slot 601 match those of the hook foot 12. The hook foot 12 can be tightly inserted into the slot 601 of the rubber sleeve 6, that is, the rubber sleeve 6 can be tightly wrapped around the hook foot 12. In this embodiment, the hook foot 12 at the bottom of the clamp arm 11 is wrapped with a rubber sleeve 6, so that the inner wall of the workpiece can be protected during lifting to avoid production wear and tear, and it can also have an anti-slip effect. The installation and removal of the rubber sleeve 6 is also very convenient, so that it can be quickly replaced.
[0025] An elastically movable baffle plate 4 is correspondingly installed on the inner side of the clamp arm 11, and a rubber pad 5 is correspondingly installed on the end surface of the baffle plate 4 away from the clamp arm 11. A plurality of springs 3 are correspondingly installed on the inner side of the clamp arm 11, one end of the spring 3 is correspondingly connected to the side wall of the clamp arm 11, and the other end of the spring 3 is correspondingly connected to the baffle plate 4. In this embodiment, the clamp walls 11 on both sides of the clamp hook 1 are arranged through the arrangement of the spring 3, the baffle plate 4 and the rubber pad 5, so as to effectively prevent the clamp walls 11 on both sides of the clamp hook 1 from directly contacting and squeezing the side ends of the workpiece such as the wind turbine nacelle during operation, thereby avoiding the effects of wear and indentation on the workpiece caused by squeezing.
[0026] A proximity switch 2 is also installed in the middle position of the upper side of the clamp hook 1. A pressure sensor is installed on the inner side of the rubber pad 5. The pressure sensor and the proximity switch 2 can be connected to the external control system. The control system described here can also be used to control the extension and retraction of the clamp arms 11 on both sides of the clamp hook 1. In this embodiment, the proximity switch 2 is set so that the distance between the clamp hook 1 and the workpiece can be sensed when the clamp hook 1 descends, so that the clamp hook 1 can stop descending in time to avoid it hitting the workpiece and causing damage to the workpiece. The pressure sensor in the rubber pad 5 is set so that the corresponding signal can be sensed when the workpiece squeezes the rubber pad 5, so that the clamp arms 11 on both sides of the clamp hook 1 can be controlled to stop extending and retracting in time to avoid excessive squeezing of the clamp arms 11 on both sides of the workpiece and causing wear.
