Description

Technical Field

[0001] This utility model relates to the field of building component assembly technology, and in particular to a connecting rod replacement device for bolted ball grid frame. Background Technology

[0002] Currently, with the continuous application and development of spatial structures, steel space frame structures are widely used in the construction field due to their reasonable stress distribution, structural stability, and novel design. Most existing steel space frames are assembled from prefabricated components, mainly consisting of bolted balls and detachable connecting rods mounted on the bolted balls. During the jacking, lifting, hoisting, and installation of the space frame, uneven stress or improper operation can cause a small number of members to bend, resulting in changes in performance. This leads to a shift in axial force, reducing the load-bearing capacity of the members and potentially jeopardizing structural safety. To ensure the structural strength of the steel space frame, bent connecting rods need to be replaced after hoisting.

[0003] The existing Chinese patent CN113653356A discloses "a method for replacing the connecting rod of a bolt ball net frame, which uses two support rods respectively set on both sides of a bent connecting rod; before fixing, the distance between the support rod and the clamping plate is adjusted so that the end of the support rod abuts and fixes the clamping plate against the bolt ball; each clamping plate is provided with two adjusting bolts with ends penetrating the clamping plate and placed inside the support rod, and each adjusting bolt is fitted with an adjusting nut and a locking nut placed between the clamping plate and the support rod"; the support rod supports the bolt ball by adjusting the nuts and locking nuts. However, this method requires turning the nuts to adjust the distance, but due to the threaded design of the nuts, many turns are required to adjust a small distance, which makes adjusting the length of the support rod time-consuming, resulting in low efficiency in replacing the connecting rod of the bolt ball net frame. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A connecting rod replacement device for a bolted ball net frame includes two symmetrically arranged support members, and two sets of adjustable-spacing support mechanisms are rotatably installed between the two support members.

[0006] The support member is a C-shaped rod-like component;

[0007] The support mechanism includes a first support rod and a second support rod. A first rotating shaft for rotation is installed at the connecting end of the first and second support rods. A second rotating shaft for rotation is installed at the free end of the first and second support rods, and the second rotating shafts are installed on the support member. A jack is provided on the side of the first and second support rods. A third rotating shaft for rotation is installed at both ends of the jack. The third rotating shaft at one end of the jack housing is connected to the second support rod, and one end of the telescopic end of the jack is connected to the first support rod.

[0008] The two support members are disposed between the two bolt balls, and the support members are sleeved on the outside of the connecting part, and the bolt balls and the connecting rod are connected by the connecting part.

[0009] As an improvement to the above technical solution, the two sets of support mechanisms are located on the same plane, and the first support rod, the second support rod, and the jack are also located on the same plane.

[0010] As an improvement to the above technical solution, the first support rod and the second support rod have the same length, and the first support rod and the second support rod of the two sets of support mechanisms form a rhombus quadrilateral.

[0011] As an improvement to the above technical solution, a detachable closure is installed at the opening of the support member.

[0012] As an improvement to the above technical solution, one end of the closed body is rotatably mounted on one side of the opening of the support member, and the other end is snapped onto the other side of the opening.

[0013] As an improvement to the above technical solution, the rotation direction of the closed body and the support member are in the same plane.

[0014] As an improvement to the above technical solution, the support member is provided with a slot, and the end of the closed body away from the rotation node is provided with a locking body. The locking body and the slot are positioned correspondingly and are fitted together.

[0015] The beneficial effects of this utility model are:

[0016] Two sets of adjustable-spaced support mechanisms symmetrically arranged between two support members facilitate the adjustment of the distance between the two support members. These adjustable support members support the two bolt balls, allowing for easy removal and replacement of the connecting rods installed between the two bolt balls without stress, thus increasing the convenience of replacing the connecting rods of the bolt ball grid frame. The "C"-shaped support members allow for easy clamping onto the outside of the connection portion to support the bolt balls. The support mechanism consists of a first support rod, a second support rod, a first rotating shaft, a second rotating shaft, a jack, and a third rotating shaft. The connection between the first and second support rods is via the first rotating shaft, while the second rotating shaft, installed at the free ends of the first and second support rods, connects to the support members. This facilitates adjustment of the distance between the two support members as the first and second support rods rotate. The jack, mounted on the first and second support rods via the third rotating shaft, allows the first and second support rods to rotate around the first rotating shaft when the jack's extension end is extended, achieving the purpose of adjusting the distance between the two support members.

[0017] Before the jack extends, seal the opening of the closed support component with the closed body to avoid problems such as the support component tilting and deformation when it is pushed from the middle to both sides. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0024] Please see Figure 1-2This utility model provides a technical solution: a connecting rod replacement device for a bolt ball net frame, comprising two symmetrically arranged support members 4, with two sets of adjustable-spaced support mechanisms rotatably installed between the two support members 4; the two sets of adjustable-spaced support mechanisms symmetrically arranged between the two support members 4 facilitate the adjustment of the spacing between the two support members 4, thereby supporting the two bolt balls 1 with the two support members 4 with the adjustable spacing, thus facilitating the removal and replacement of the connecting rod 2 installed between the two bolt balls 1 without stress, increasing the convenience of replacing the connecting rod of the bolt ball net frame.

[0025] The support member 4 is a C-shaped rod-like component; and the C-shaped structure of the support member 4 makes it easy for the support member 4 to fit around the outside of the connecting part 3 and support the bolt ball 1.

[0026] The support mechanism includes a first support rod 5 and a second support rod 6. A first rotating shaft 7 for rotation is installed at the connecting end of the first support rod 5 and the second support rod 6. Second rotating shafts 8 for rotation are respectively installed at the free ends of the first support rod 5 and the second support rod 6, and the second rotating shafts 8 are mounted on the support member 4. Jacks 9 are provided on the sides of the first support rod 5 and the second support rod 6. Third rotating shafts 10 for rotation are installed at both ends of the jacks 9, and one end of the third rotating shaft 10 at the housing of the jack 9 is connected to the second support rod 6. One end of the telescopic end of the jack 9 is connected to the first support rod 5. The mechanism is constructed by the first support rod 5, the second support rod 6, and the second support rod 6. The support mechanism consists of a first rotating shaft 7, a second rotating shaft 8, a jack 9, and a third rotating shaft 10. The connection between the first support rod 5 and the second support rod 6 is rotated via the first rotating shaft 7. The second rotating shaft 8, which is installed at the free end of the first support rod 5 and the second support rod 6, is connected to the support member 4, thereby facilitating the adjustment of the distance between the two support members 4 when the first support rod 5 and the second support rod 6 rotate. The jack 9 is rotatably installed on the first support rod 5 and the second support rod 6 via the third rotating shaft 10. When the telescopic end of the jack 9 extends, it causes the first support rod 5 and the second support rod 6 to rotate around the first rotating shaft 7, thereby achieving the purpose of adjusting the distance between the two support members 4.

[0027] Specifically, the two sets of support mechanisms are located on the same plane, and the first support rod 5, the second support rod 6, and the jack 9 are also located on the same plane.

[0028] In this embodiment, by using two sets of support mechanisms located on the same plane, and with the first support rod 5, the second support rod 6, and the jack 9 also located on the same plane, the support member 4 can be stably supported by the two sets of support mechanisms, which facilitates the adjustment of the force on the connecting rod 2 between the two bolt balls 1 by the support member 4.

[0029] Specifically, the first support rod 5 and the second support rod 6 have the same length, and the first support rod 5 and the second support rod 6 of the two sets of support mechanisms form a rhombus quadrilateral.

[0030] Specifically, the support member 4 is disposed between the two bolt balls 1, and the support member 4 is sleeved on the outside of the connecting part 3. The bolt balls 1 and the connecting rod 2 are connected through the connecting part 3.

[0031] In this embodiment, after the support member 4 adjusts the spacing, the two bolt balls 1 are pushed outward from the middle to both sides, so that the connecting rod 2 installed between the two bolt balls 1 is not under force.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, a detachable closure body 11 is installed at the opening of the support member 4. One end of the closure body 11 is rotatably mounted on one side of the opening of the support member 4, and the other end is snapped onto the other side of the opening. The rotation direction of the closure body 11 is in the same plane as the support member 4. The support member 4 is provided with a slot, which is a recessed structure. A locking structure is provided on the side of the slot facing the card body 12. The locking structure can be an elastic locking pin or a permanent magnet to fix the card body 12. The end of the closure body 11 away from the rotation node is provided with the card body 12. The card body 12 and the slot are positioned correspondingly and are fitted together.

[0033] After the opening of the support member 4 enters between the two bolt balls 1, the support member 4 is closed by closing and sealing the opening side of the support member 4 with the closing body 11, thereby realizing the annular closed structure of the support member 4. There will be no problems such as skewing or deformation when the first support rod 5 and the second support rod 6 are supported.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
