Description

Technical Field

[0001] This application relates to the field of sling support, and more particularly to a sling support device. Background Technology

[0002] Hangers are an important component of modern construction equipment. For example, hanging baskets are crucial equipment in continuous beam construction, utilizing numerous hangers. Existing hanger support devices can adjust length during construction, but cannot simultaneously adjust angle. Furthermore, hangers are often made of rigid members such as precision-rolled threaded steel. When the angle of the hanger needs to be changed during construction, the inability of the support mechanism to rotate makes angle adjustment difficult, increasing construction complexity. This also exposes the hanger to bending moment loads, leading to unfavorable stress distribution and increasing the risk of safety accidents.

[0035] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0036] In the process of developing this application, the inventors discovered that existing rod support devices can achieve length adjustment during construction, but cannot simultaneously adjust the angle. Furthermore, rods are often made of rigid members such as precision-rolled threaded steel. When the angle of the rod needs to change during construction, the rod support mechanism cannot rotate, making it difficult to change the rod angle, increasing the construction difficulty, and causing the rod to bear bending moment loads, resulting in unfavorable stress and a high risk of safety accidents.

[0037] To address the aforementioned issues, this application provides a boom support device.

[0038] Example

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, a boom support device includes: a through-hole jack 10, a boom 20, a connector 30, and a support base 40. The boom 20 passes sequentially from top to bottom through the through-hole jack 10, the connector 30, and the support base 40, extending out of the support base 40. The top of the boom 20 is connected to the through-hole jack 10. The support base 40 has a groove 401. The connector 30 includes a limiting block 301, the shape of which matches the shape of the groove 401, allowing for omnidirectional rotation between the limiting block 301 and the groove 401.

[0040] In practical implementation, the structure of the connector 30 is unrestricted. The connector 30 connects the through-hole jack 10 and the support base 40. The structure of the support base 40 is also unrestricted. The support base 40 supports the through-hole jack 10, and the entire support device is fixed by fixing the support base 40. In use, the support base 40 is first fixed at the desired installation position, which can be two channel steels 70. Then, the lifting rod 20 passes through the through-hole jack 10, the connector 30, and the support base 40 sequentially from top to bottom. The upper end of the lifting rod 20 connects to the through-hole jack 10, and the lower end of the lifting rod 20 extends downwards through the support base 40. The support base 40 has a groove 401, the shape of which matches the shape of the limiting block 301. Through the cooperation between the limiting block and the groove, the lifting rod can rotate freely at various angles, avoiding bending moment loads on the lifting rod, improving construction efficiency, and reducing construction costs. Figure 2 , Figure 3 As shown, a rod support device is provided, wherein the limiting block 301 is a column with a spherical outer peripheral surface, the top of the limiting block 301 is connected to the bottom of the through-hole jack 10, the bottom of the limiting block 301 is located in the groove 401, and the outer peripheral surface of the limiting block 301 is in contact with the inner side of the groove 401.

[0041] As a preferred embodiment, the bottom diameter of the limiting block 301 is larger than the bottom diameter of the groove 401, there is a gap between the bottom of the limiting block 301 and the bottom of the groove 401, and a through hole 402 is provided between the bottom of the groove 401 and the bottom of the support base 40, through which the lifting rod 20 passes.

[0042] As a preferred embodiment, the through hole 402 is a circular hole, and the diameter of the circular hole is larger than the diameter of the lifting rod 20;

[0043] In practical implementation, the limiting block 301 is a cylinder with a spherical outer surface, located at the bottom of the through-hole jack 10. Similarly, the support base 40 has a groove 401 matching the shape of the limiting block 301. When the limiting block 301 is located within the groove 401 of the support base 40, it can rotate within the groove 401. Since the diameter of the through hole 402 between the groove 401 and the bottom of the support base 40 is larger than the diameter of the lifting rod 20, ... Figure 5 , Figure 6 As shown, this allows both ends of the boom 20 to rotate freely around the support base 40, preventing the boom 20 from bearing bending moment loads, improving construction efficiency, and reducing construction costs. Since there is a gap between the bottom of the limit block 301 and the bottom of the groove 401, the boom is guaranteed to meet the rotation requirements without exceeding the rotation limit, thus ensuring safety while fulfilling its function.

[0044] As a preferred option, the shape of the limiting block 301 is not limited and can be hemispherical, as long as the limiting block 301 and the groove 401 can rotate in all directions.

[0045] As a preferred embodiment, the connector 30 further includes at least three columns 302, which are respectively spaced between the bottom of the through-hole jack 10 and the top of the limiting block 301. The two ends of the three columns 302 are respectively connected to the bottom of the through-hole jack 10 and the top of the limiting block 301, and the lifting rod 20 is located between the three columns 302.

[0046] In practice, the number of columns 302 is at least three. The columns 302 are set between the bottom of the through-hole jack 10 and the top of the limit block 301, which can provide operating space for the assembly of the locking nut 202.

[0047] like Figure 5As shown, a boom support device includes: a boom 20 with an adjusting nut 201 and a locking nut 202, and the boom 20 with threads that match the adjusting nut 201 and the locking nut 202. The adjusting nut 201 is located at the top of the through-hole jack 10, and the locking nut 202 is located between the bottom of the through-hole jack 10 and the top of the limiting block 301. When the through-hole jack 10 is completely unloaded, the locking nut 202 abuts against the top of the limiting block 301, and there is a gap between the adjusting nut 201 and the top of the through-hole jack 10.

[0048] In practical implementation, the adjusting nut 201 is used to adjust the extension length of the boom, and the locking nut 202 is used to lock the boom. The through-hole jack 10, the adjusting nut 201 and the locking nut 202 cooperate with each other to realize the extension adjustment of the boom 20. When the through-hole jack 10 is completely unloaded, the boom 20 is under vertical load, and the locking nut 202 abuts against the limit block 301, while there is a certain gap between the adjusting nut 201 and the top of the through-hole jack 10.

[0049] In the above scheme, three columns are used to provide operating space for the locking nut 202.

[0050] like Figure 4 , Figure 5 As shown, a rod support device includes: a cylindrical support base 40, a fixed base plate 60 on the outer side of the bottom of the support base 40, and a fixing bolt 601 on the fixed base plate 60 for fixing the support base 40 at the required installation position; the cylindrical support base 40 is easy to process and produce.

[0051] In practical implementation, a ring of fixing base plate 60 is set on the outer side of the bottom of the support base 40. Bolt holes are opened on the fixing plate 60. The fixing bolts 601 pass through the bolt holes on the fixing plate 60 and the bolt holes on the channel steel 70 in sequence, and are then tightened with nuts, which makes it easier to fix the support base 40 between the two channel steels.

[0052] As a preferred embodiment, the support base 40 is provided with a retaining plate 50 and a retaining plate bolt 501 on its top. The top of the support base 40 is connected to the retaining plate 50 by the retaining plate bolt 501. The retaining plate 50 has a through hole, the diameter of the bottom of the through hole is the same as the diameter of the top of the groove 401, and the diameter of the top of the through hole is smaller than the diameter of the top of the groove. The inner wall of the through hole is spherical, and the limiting block 301 is placed inside the groove 401, with the outer surface of the limiting block 301 in contact with the inner wall of the through hole of the retaining plate 50.

[0053] Specifically, the card plate 50 can be made up of two semi-circular rings joined together, which makes it easy to assemble and disassemble.
