Description

Technical Field

[0001] The invention relates to the technical field of slings, in particular to a sling device for a cone-shaped frame product. Background Art

[0002] For conical structure products with spatial round tube interfaces and round tubes distributed at a certain angle around the product axis, it is necessary to tighten the outward-inclined round tubes, but the installation freedom is limited, resulting in huge challenges in connection and assembly. Especially when the product installation space is limited, it becomes particularly difficult to connect the entire hanger to each inclined round tube. If there is no additional installation space at the small end (i.e. the bottom) of the conical structure, the disassembly and assembly of the hanger will be extremely difficult, and it may even take several hours to complete the connection between the hanger and the product, which is both laborious and time-consuming.

[0003] The lifting space is a cone-shaped structure composed of a series of round tubes arranged at a specific angle to the axis, where the large diameter end is located at the top of the product and the small diameter end is located at the bottom, ready for lifting. A clamp needs to be installed below the inclined round tube at the large diameter end (close to the end face of the product). The clamp is divided into two parts, each of which is connected to three inclined round tubes (for the six-tube cone-shaped structure product lifted this time, each half clamp is connected to three round tubes). On each half clamp, it is connected to the round tube of the product through three supports. The supports are usually installed directly below the inclined round tube, and the clamp is located above the supports to connect the product round tube and the hoist. Since the product round tube is in the shape of an arc, the contact surface between the support and the round tube must also be in the shape of an arc. The clamp forms a ring structure around the product, and the three supports evenly distributed on each semicircular clamp need to be connected to the three inclined round tubes at the same time. Therefore, the clamp usually needs to be sent upward from the lower end of the cone to the installation position. However, when the space at the lower end of the cone is limited or there is interference, the clamp with three supports cannot be installed on the product as a whole. In this case, it is necessary to consider installing two supports on the half clamp to connect with the product, and then insert the third support between the round tube and the clamp. This process requires repeated debugging and verification with the positions of the other two installed supports. The installation process may take several hours, which is extremely inconvenient, laborious and time-consuming.

[0004] Therefore, a hanger device for a cone-shaped frame product is proposed. Summary of the invention

[0036] In this embodiment, the first connecting structure includes a clamping mechanism 2, and the clamping mechanism 2 is provided with multiple groups. The multiple groups of clamping mechanisms 2 are all installed on the annular clamp 1 with adjustable positions. The clamping mechanism 2 includes an L-shaped plate 201 and an inverted L-shaped plate 202. The L-shaped plate 201 is arranged on the outer side of the annular clamp 1, and the inverted L-shaped plate 202 is arranged on the inner side of the annular clamp 1. The L-shaped plate 201 and the inverted L-shaped plate 202 are fixed to the annular clamp 1 by a first bolt 204. The upper end of the inverted L-shaped plate 202 is formed with a mounting portion 2021, and a clamp 203 is detachably installed on one side of the mounting portion 2021 by a second bolt 205. In order to fit the upper end of the product round tube more closely, an arc groove 2022 is provided on the side of the mounting portion 2021 close to the clamp 203.

[0037] Through the above arrangement, when fixing the product, the annular clamp 1 is sent to the predetermined position from the side of the product, and the clamping mechanism 2 is moved along the arc surface of the annular semicircular clamp 101 to the position of the product round tube, so that the round tube fits in the arc groove 2022, and then the second bolt 205 is tightened, and then the round tube of the product is clamped on the arc groove 2022 through the clamp 203, and then the first bolt 204 is tightened to fix the clamping mechanism 2 on the annular clamp 1, and then the two semicircular clamps 101 are fixed by bolts. It is not necessary to send it upward from the small diameter end of the conical frame, and the installation position is not limited by the installation space. For lifting such a conical frame structure composed of inclined round tubes in space, the connection operation is convenient, saving time and effort.

[0041] By setting the lifting hole 103 in conjunction with the center of gravity adjusting sling 6, when the center of mass of the product deviates from the axis, the second car hook is additionally connected through the lifting hole 103 near the center of mass to protect the bottom end surface of the product from being damaged due to the tilted state off the ground caused by the center of mass deviating from the axis. The length of the center of gravity adjusting sling 6 can be adjusted by the first hand winch 602.

[0042] Example 2

[0043] The lifting point of the sling is often provided with a mounting hole for connecting the rotating eye screw 10. Generally, the plate is welded at the lifting position to increase the thickness, and then the threaded hole is drilled. After drilling, there is a gap between the welded plate and the sling body on the threaded hole wall, resulting in an incomplete closure of the sling, affecting the surface treatment effect such as galvanizing, and easily causing product corrosion.

[0044] In this embodiment, a second connecting structure for fixing to the top of the product is provided on the main mechanism, wherein the main mechanism includes a female seat 7, which is arranged in a ring shape, and an annular seat 8 is fixedly welded to the bottom of the female seat 7, and a plurality of reinforcing ribs 9 are fixedly welded between the top of the annular seat 8 and the outer wall of the female seat 7, and the second connecting structure includes a groove surface 802, and the groove surface 802 is in contact with the top of the product, and a first connecting hole 801 connected to the groove surface 802 is opened on the top of the annular seat 8.

[0045] By setting the groove surface 802, the product can be fitted with the groove surface 802 during installation to ensure the installation effect. During installation, the bolt passes through the first connecting hole 801 and is threadedly installed on the top of the product to achieve the connection between the product and the annular seat 8.

[0046] In this embodiment, the annular seat 8 is provided with a second suspension member, and the second suspension member includes a second sling 11 and a second hand winch 12. A second connecting hole 803 is opened on the top of the annular seat 8, and three second connecting holes 803 are arranged. The three second connecting holes 803 are distributed on the annular seat 8 in a circular equidistant array. A step rod 1001 is fixedly welded inside the second connecting hole 803, and a threaded hole is opened on the top of the step rod 1001. A rotating eye screw 10 is fixedly connected to the thread in the threaded hole. The rotating eye screw 10 is fixedly connected to the lower end of the second hand winch 12, and the upper end of the second hand winch 12 is fixedly connected to the lower end of the second sling 11, and the upper end of the second sling 11 is fixedly connected to the hook of the third overhead crane.

[0047] Through the above arrangement, the connection between the annular seat 8 and the third overhead traveling vehicle hook is achieved, so as to facilitate lifting the product.

[0048] In this embodiment, the annular seat 8 is made of 16 mm thick plate material, which is cut into a circular ring shape. When welding the step rod 1001, grooves for welding are opened at the top and bottom of the second connecting hole 803 to ensure the welding quality and improve the sealing of the weld, thereby ensuring the overall sealing of the sling. The sling solves the problem that the sling cannot be completely closed, and the structure is safe and simple, which is easy to produce.
