Description

Technical Field

[0001] The utility model relates to the technical field of guide frames, in particular to a steel strand guide frame used for hydraulic synchronous lifting of steel structures. Background Art

[0002] The hydraulic overall lifting technology for large components is a novel construction installation technology. It uses hydraulic lifters as lifting equipment and steel strands as load-bearing rigging for lifting components. The overall lifting and installation of large components is achieved through the lifting and lowering of the hydraulic lifters.

[0003] For example, a steel strand guide frame for hydraulic synchronous lifting of steel structure proposed by announcement number CN205773011U includes a guide frame support frame and a guide frame, wherein the guide frame support frame is composed of vertical support rods, oblique support rods, longitudinal support rods and transverse support rods; the vertical support rods are a pair of parallel and equal vertical support rods, and the two vertical support rods are connected by a longitudinal support rod; the oblique support rods are two parallel and equal oblique support rods, one end of the two oblique support rods is fixed at the same height as the vertical support rods, and the other end is supported on the lifting beam, and a longitudinal support rod is arranged between the two oblique support rods; the vertical support rod and the oblique support rod are connected by a transverse support rod; the guide frame includes two mutually mirror-symmetrical tripods, and the three corners of the two tripods are respectively connected by three parallel supporting circular tubes; one of the supporting circular tubes of the guide frame is installed between the two vertical support rods on the upper part of the guide frame support frame. The utility model can be made of local materials, can be reused, and can effectively support steel strands.

[0004] When the tripod is used to support the steel strand, since the tripod itself does not have a limiting function and the steel strand has a certain elasticity, the steel strand is prone to slip when it moves. Once the steel strand slips, it will cause the steel strand to be entangled, making it difficult to sort out. This situation will not only affect the construction efficiency, but may also have an adverse effect on the construction quality.

[0005] To this end, the utility model provides a steel strand guide frame for hydraulic synchronous lifting of steel structures. Utility Model Content

[0031] like Figure 1 and Figure 3As shown in the figure, the positioning component 8 includes a connecting block 81, and the connecting block 81 is arranged in a "U" - shaped structure, which is convenient for multiple steel strands 3 to pass through simultaneously. An installation groove 82 is opened on the upper surface of the connecting block 81. A roller 83 is rotatably arranged inside the installation groove 82 through a bearing, and a plurality of guiding grooves are opened on the outer wall of the roller 83, which can prevent multiple steel strands 3 from slipping or crossing each other during movement. One end of the connecting block 81 is fixedly connected with a guiding block 84, and the guiding block 84 is slidably connected with the guiding groove 7. The other end of the connecting block 81 is fixedly connected with a first sleeve block 85, and the first sleeve block 85 is movably sleeved on the guiding column 5. A first fixing block 86 is fixedly connected to the outer wall of the first sleeve block 85. The connecting block 81 can be arranged on both the left and right sides of the guiding column 5, so as to divide multiple steel strands 3 into multiple groups for guiding and limiting, avoid the steel strands 3 from winding, crossing and knotting, reduce the risk of wear and fracture of the steel strands 3, and improve safety.

[0032] Furthermore, the positioning component 8 further includes a limiting plate 87 movably sleeved on the guiding column 5 and the guiding rod 6. The limiting plate 87 is located directly above the connecting block 81. Second fixing blocks 88 are respectively and fixedly arranged on both sides of the limiting plate 87. An adjusting threaded rod 89 is threaded through the second fixing block 88, and a hand - turning nut is arranged at the upper end of the adjusting threaded rod 89.

Multiple groups of connecting blocks 81 can be installed simultaneously, and the second fixing block 88 can limit the steel strands 3 on the uppermost connecting block 81 to ensure the stable movement of the steel strands 3 and avoid slipping and knotting.

[0033] As Figure 1 shown in the figure, the supporting component 4 includes two groups of vertical supporting rods 41 and inclined supporting rods 42. A plurality of cross braces 43 are fixedly arranged between the vertical supporting rods 41, and the vertical supporting rods 41 and the cross braces 43 are welded together, which is convenient for stably supporting the vertical supporting rods 41. The inclined supporting rods 42 are inclined, and the connection part is welded.

[0036] The working principle of this embodiment is as follows: according to the number of rows of steel strands 3 arranged on the lifter 2, the guide block 84 at one end of the connection block 81 is slidably placed inside the guide groove 7, and at the same time, the first set block 85 at the other end of the connection block 81 is sleeved on the outer wall of the guide column 5, so that the connection block 81 slides to the lowest end of the guide column 5. Then, according to the number of rows of steel strands 3, the steel strands 3 in the first row are divided into two groups, which are respectively placed on the rollers 83 in the mounting grooves 82 on both sides of the guide rod 6, and each group of steel strands 3 is respectively placed in the corresponding guide grooves on the rollers 83, so as to facilitate the guidance of the steel strands 3 and avoid mutual crossing and entanglement during the movement.

[0037] Further, after the first row of steel strands 3 are placed, the second group of connection blocks 81 are placed on the first group of connection blocks 81 again according to the above, which will not be described here. Then the second row of steel strands 3 are divided into two groups, which are also placed in the corresponding guide grooves on the rollers 83, so as to achieve the row-by-row guide support of the steel strands 3. During the movement of the steel strands 3, the steel strands 3 drive the rollers 83 to rotate in the installation grooves 82, and guide them during the movement to avoid slipping, crossing and winding, thereby improving safety.

[0038] In a specific embodiment, the number of rows of the steel strands 3 is set according to the arrangement of the through holes on the lifter 2, and the number of rows of the connecting blocks 81 of the positioning assembly 8 from bottom to top matches the number of rows of the steel strands 3.

[0039] Furthermore, after the steel strand 3 is placed, the limit plate 87 is movably mounted on the guide column 5 and the guide rod 6, and the lower end of the adjusting threaded rod 89 is connected to the threaded hole on the first fixed block 86, and then the hand-screw nut at the upper end of the adjusting threaded rod 89 is rotated to move the limit plate 87 vertically downward, and the connecting block 81 and the limit plate 87 are connected, so as to prevent the steel strand 3 from slipping and entanglement, thereby improving the construction efficiency and increasing the construction quality.

[0040] Furthermore, as the lifter 2 operates, the length of the steel strand 3 passing through the positioning assembly 8 continues to increase. In order to prevent the steel strand 3 from falling onto the supporting assembly 4, manual assistance is required to push the free ends of the steel strand 3 to both sides of the supporting assembly 4 so that the steel strand 3 can fall naturally.
