Description

Technical Field

[0001] This utility model relates to the field of rigging technology, and in particular to an adjustable steering rigging. Background Technology

[0002] Rigging is mainly used to withstand the forces generated between objects in opposite directions, and is used to connect two objects to each other, thereby fixing them in place.

[0003] In existing technologies, such as the adjustable steering rigging described in patent CN218754519U, a swivel ring is installed inside the guide rod and threadedly connected to the screw to extend the hook in order to solve the problem of difficulty in adjusting the rigging's length. This results in the need to insert the swivel ring between the two guide rods when turning it, making it difficult to turn the wrench. Furthermore, the lack of a direct connection between the swivel ring and the fixed seat leads to a situation where the screw remains stationary while the swivel ring descends relative to the screw, especially when the lifting ring and hook are respectively secured to heavy objects. The resulting reverse force further tightens the connection between the screw and the fixed seat, making it even more difficult to turn the screw. Therefore, the existing technology has certain shortcomings, necessitating an adjustable steering rigging to solve these problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-5 This utility model provides an adjustable steering rigging, comprising: The upper fixed body 1 has an upper connecting rod 2 passing through it. The upper connecting rod 2 is rotatably connected to the upper fixed body 1. The top end of the upper connecting rod 2 extends out of the upper fixed body 1 and is welded with a lifting ring 3. The lower fixed body 4 has a lower connecting rod 5 passing through it. A connector is provided inside the lower fixed body 4. The connecting end of the connector is connected to the lower connecting rod 5. The lower connecting rod 5 is fixed relative to the lower fixed body 4. A hook 6 is connected to the bottom end of the lower connecting rod 5. The lower fixed body 4 and the upper fixed body 1 are defined by a sliding range. The lower fixed body 4 is fitted with a nut 7. The lower connecting rod 5 is threadedly connected to the upper connecting rod 2. The lower fixed body 4 can move within the sliding range.

[0019] In this invention, an upper connecting rod 2 is connected inside the upper fixed body 1, and a lifting ring 3 is welded to the top of the upper connecting rod 2, so that the lifting ring 3 is rotatably connected to the upper fixed body 1, preventing the lower fixed body 4 from jamming with the upper fixed body 1. The bottom end of the lower connecting rod 5 extends out of the lower fixed body 4 and is connected to a hook 6. After the hook 6 is hoisted with the heavy object, it can meet the swivel connection of the heavy object. In addition, the lower connecting rod 5 is threaded to the upper connecting rod 2, and a fixing nut 7 is provided on the lower fixed body 4 to facilitate the rotation of the lower fixed body 4. The lower connecting rod 5 is fixed to the lower fixed body 4 by the connecting piece, thereby realizing the rotation of the lower connecting rod 5 and the telescopic adjustment of the lower connecting rod 5 relative to the upper connecting rod 2. Furthermore, a sliding range is defined between the upper fixed body 1 and the lower fixed body 4, which can limit the upper fixed body 1 and the lower fixed body 4 when adjusting the distance between the lifting ring 3 and the hook 6, thereby improving the stability of the lower fixed body 4 during adjustment and movement.

[0020] Specifically, when the lifting ring 3 is connected to the lifting equipment or heavy object, the upper connecting rod 2 is fixed, and the lower fixing body 4 is relatively fixed to the lower connecting rod 5. The threaded connection between the upper connecting rod 2 and the lower connecting rod 5 can be adjusted in length. The upper fixing body 1 is rotatably connected relative to the upper connecting rod 2. The lower fixing body 4 and the upper fixing body 1 can rotate synchronously or independently. This improves the rotational freedom between the structures when adjusting the overall steering rigging, allowing personnel to easily and effectively rotate the nut 7 to drive the lower fixing body 4 and the lower connecting rod 5 to rotate.

[0021] Furthermore, the connector includes: Connecting seat 8 is fixedly connected to the top surface of lower fixed body 4, and lower connecting rod 5 passes through connecting seat 8; The connecting key 9 is embedded in the key groove of the connecting seat 8 and fixed relative to the connecting seat 8. The connecting key 9 is sleeved and welded to the outside of the lower connecting rod 5.

[0022] By fixing the connecting seat 8 to the lower fixed body 4 and installing a fixing key 9 on the lower connecting rod 5, the connecting key 9 is embedded and fixed to the connecting seat 8, so that the lower connecting rod 5 and the lower fixed body 4 can rotate synchronously.

[0023] Furthermore, an upper limit ring 10 is fixedly connected to one end of the upper connecting rod 2 that extends into the upper fixed body 1. A sleeve 11 is fixedly connected to the bottom surface of the upper limit ring 10. The inner wall of the sleeve 11 is threaded, and a screw 12 is threadedly connected to the inner thread of the sleeve 11. The bottom end of the screw 12 extends out of the sleeve 11 and is fixedly connected to the lower connecting rod 5.

[0024] By snapping the upper limit ring 10 into the upper fixed body 1, fixing the upper connecting rod 2 to the upper fixed body 1, and rotatably connecting the upper limit ring 10 into the upper fixed body 1, by welding a sleeve 11 to the bottom end of the upper limit ring 10 and threading a screw 12 into the sleeve 11, the screw 12 is coaxially fixed to the lower connecting rod 5. When adjusting the steering rigging, the lifting ring 3 is connected and fixed to the lifting equipment to prevent the upper connecting rod 2 and the lower connecting rod 5 from rotating synchronously.

[0025] Furthermore, it also includes: The sliding sleeve 13 is fixedly connected to the top surface of the connecting seat 8. The bottom surface of the upper fixing body 1 has a groove, and the top end of the sliding sleeve 13 extends vertically upward into the groove. The retaining ring 14 is sleeved and fixed to one end of the sliding sleeve 13 that extends into the upper fixed body 1. The inner side wall of the groove has a retaining groove, which is a sliding area, and the retaining ring 14 slides in the retaining groove.

[0026] The retaining ring 14 is inserted into the groove of the upper fixing body 1 by the sliding sleeve 13, and the retaining ring 14 is slidably engaged in the retaining groove opened in the inner side wall of the groove, so that the retaining ring 14 and the retaining groove cooperate to limit the sliding connection between the upper fixing body 1 and the lower fixing body 4. The ring structure of the retaining ring 14 and the rotatable connection between the upper fixing body 1 and the upper connecting rod 2 can effectively avoid affecting the rotation of the lower fixing body 4, thus facilitating personnel to make adjustments.

[0027] Furthermore, the length of the slot in the vertical direction is the same as the length of the screw 12.

[0028] The threaded connection between the screw 12 and the upper connecting rod 2 is limited by the retaining ring 14 to prevent the screw 12 from disengaging from the upper connecting rod 2.

[0029] Furthermore, a support seat 15 is fixedly connected to the inner wall of the top of the groove, and the sleeve 11 passes through the center of the support seat 15. The outer periphery of the support seat 15 slides in contact with the inner ring of the sliding sleeve 13.

[0030] By having the support seat 15 slide in contact with the inner wall of the sliding sleeve 13, the support stability of the sliding sleeve 13 is improved. It can be understood that the diameter of the support seat 15 is larger than the through hole through which the upper connecting rod 2 passes through the upper fixing body 1, so as to ensure that there is sufficient contact area between the upper fixing body 1 and the support seat 15 for connection and fixation.

[0031] Furthermore, the upper fixing body 1 includes a base 101 and a support 102. A groove is provided at the center of the top surface of the base 101, and an upper limit ring 10 is embedded in the groove. A number of threaded holes are provided at equal intervals in the circumferential direction on the top surface of the base 101 away from the groove. A number of bolt holes are provided in the circumferential direction on the support 102. A connecting bolt 16 is correspondingly slidably connected in the bolt holes. The bottom end of the connecting bolt 16 is threadedly connected to the adjacent threaded hole. The top surface of the upper limit ring 10 is engaged with the bottom surface of the support 102.

[0032] The base 101 and the support 102 are detachably connected by several connecting bolts 16. While the support 102 and the base 101 are fixed, the support 102 limits and engages the upper limit ring 10, and the upper limit ring 10 is embedded in the groove, thereby realizing the rotatable fixation of the upper connecting rod 2 and the upper fixed body 1. Specifically, the end of the connecting bolt 16 is engaged by the step opened in the bolt hole. After the connecting bolt 16 is threadedly connected to the threaded hole, the base 101 and the support 102 are fixed. The bolt hole is conventional existing technology and will not be described in detail.

[0033] Furthermore, the bottom end of the lower connecting rod 5 extends out of the lower fixed body 4 and is connected to the hook 6 via the rotor bearing 17.

[0034] To ensure a stable connection between the hook 6 and the lower connecting rod 5, the hook 6 can be relatively fixed to the load when the lower fixed body 4 is rotated to adjust its length, thus maintaining the stability of the load during lifting.

[0035] This utility model provides a working principle for an adjustable steering rigging: The lifting equipment is fixed to the lifting ring 3, and the hook 6 is connected to the load. When the length of the steering sling is insufficient for connection, the lower connecting rod 5 is fixed to the lower fixed body 4 by directly rotating the nut 7 fixed to the outside of the lower fixed body 4. The connecting seat 8 and the connecting key 9 are used to fix the lower connecting rod 5 to the lower fixed body 4. The distance between the upper connecting rod 2 and the lower connecting rod 5 can be adjusted by threading the screw 12 to the sleeve 11. The lifting ring 3, by being fixed to the lifting equipment, can prevent the upper connecting rod 2 and the lower connecting rod 5 from rotating synchronously. In addition, the upper fixed body 1 can selectively rotate synchronously with the lower fixed body 4 to prevent the upper fixed body 1 and the lower fixed body 4 from jamming, which facilitates the rotation of the nut 7. At the same time, the sliding sleeve 13 and the retaining ring 14 can maintain the sliding stability between the upper fixed body 1 and the lower fixed body 4.

[0037] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
