Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a rotating bracket structure for quickly adjusting a jacking nut. Background Art

[0002] In the field of construction, during the erection of the formwork support system, the formwork support system is a key component to ensure the smooth progress of construction. As the core component of the formwork support system, the support frame is used in huge quantities and has a direct impact on construction efficiency and cost. The height adjustment of the traditional support frame mainly relies on manual rotation of the bracket nut. The bracket nut in the support frame needs to be adjusted up and down to make the formwork support system reach the required height. The manual rotation of the nut is slow and requires a lot of manpower and time. This process is not only inefficient, but also requires high physical strength of the workers, which can easily lead to physical fatigue and affect construction safety and project progress. At the same time, due to the huge amount of support frames, long-term manual adjustment of the bracket nuts will cause fatigue in the hands and wrists of workers, and consume a lot of labor costs.

[0003] Therefore, in view of this, the inventor provides a rotating bracket structure for quickly adjusting the jacking nut to solve the above-mentioned problem. Utility Model Content

[0004] The utility model aims to provide a rotating bracket structure for quickly adjusting a jacking nut, which can quickly complete the installation of the bracket nut and improve work efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A rotating bracket structure for quickly adjusting a jacking nut comprises an adjusting column and a bracket nut, wherein the outer circumference of the adjusting column is provided with an external thread, the bracket nut is provided with an internal thread, the external thread is adapted to the internal thread, and the bracket nut is coaxially threadedly connected to the adjusting column; when the bracket nut is rotated, the bracket nut can rise or fall along the axial direction of the adjusting column;

[0007] A driving frame, the driving frame comprising a driving column, a positioning rod mounted on the driving column and at least two torsion rods, the positioning rod being arranged at the center of the driving column; each torsion rod being used to be connected with the bracket nut, and when the torsion rod is connected with the bracket nut, the positioning rod is located inside the adjusting column;

[0008] It also includes an electric drive member. When the drive frame and the electric drive member are in an engaged state, the bracket nut forms a transmission connection with the electric drive member through the drive frame so that it can be rotated electrically.

[0009] According to the above technical solution, the bracket nut is coaxially threadedly connected to the external thread of the adjusting column through its internal thread, and then the torsion bar on the driving frame is aligned with the bracket nut, at least two torsion bars are connected to the bracket nuts, and the electric driving component is engaged with the driving frame to ensure that the torsion bar and the bracket nut form a transmission connection. When in use, the torsion bar is driven to rotate by controlling the electric driving component, and the bracket nut will be rotated electrically. When the bracket nut is rotated, it will rise or fall along the axial direction of the adjusting column, thereby quickly adjusting the support height.

[0010] Furthermore, the drive frame also includes connecting columns and connecting rods, the number of the connecting rods is the same as the number of the torsion bars, one end of each connecting rod is connected to a corresponding one of the torsion bars, the other end of each torsion bar is fixedly connected to the connecting column, and the connecting column is fixedly connected to the drive column.

[0011] According to the above technical solution, the connecting column is fixedly connected to the driving column, providing a stable support point for the entire driving frame; one end of the connecting rod is connected to the torsion bar, and the other end is fixedly connected to the connecting column. In actual use, the driving column is usually small, and the connection column is provided to facilitate welding by the staff; when the electric drive component is started, the driving force generated by it will be transmitted to the driving column, and the driving column will disperse the force to each connecting rod through the connecting column, and the connecting rod will then evenly transmit the force to the torsion bar, and the torsion bar will drive the bracket nut to rotate, so the driving force received by the torsion bar will be converted into the rotational force of the bracket nut, so that the bracket nut rises or falls along the adjusting column, thereby achieving a rapid lifting effect.

[0012] Furthermore, one end of the driving column facing away from the connecting column and the electric driving member are respectively provided with mechanical joints adapted to each other on a side close to each other.

[0013] Further, the mechanical coupling portion includes a slot and / or a pin arranged on a side of the electric drive component close to the connecting column, and a pin and / or a slot arranged on a side of the connecting column close to the electric drive component, and the pin can be inserted into the slot to achieve the coupling of the electric drive component and the drive column.

[0014] According to the above technical solution, mechanical joints that match each other are respectively provided on one end of the driving column away from the connecting column and on the side of the electric driving component close to each other. This design is to achieve a quick and stable connection between the driving column and the electric driving component; when the electric driving component needs to be connected to the driving column, it is only necessary to insert the pin on the driving column into the slot on the electric driving component (or vice versa) to achieve a stable connection between the two; once the pin is inserted into the slot, the electric driving component can transmit power to the driving column through the joint, and the driving column will then drive the entire driving frame (including the connecting column, connecting rod and torsion rod, etc.) to move, and then drive the bracket nut to rise or fall along the adjusting column, so that the connection between the electric driving component and the driving column becomes simple and quick, and the stability of the connection between the two is ensured, thereby ensuring the efficiency and stability of power transmission.

[0015] Further, the bracket nut includes a hollow stud and at least two supporting parts, and the supporting parts are evenly distributed on the periphery of the hollow stud and fixed to the hollow stud;

[0016] Each of the supporting parts is provided with at least one through hole.

[0017] According to the above technical solution, an internal thread is provided inside the hollow stud of the bracket nut, which matches the external thread on the adjusting column. When the bracket nut is threadedly connected to the adjusting column, the bracket nut can be raised or lowered along the axial direction of the adjusting column by rotating the bracket nut, thereby achieving height adjustment; the supporting part of the bracket nut is evenly distributed on the periphery of the hollow stud and is fixed to the hollow stud. This structural design enhances the stability and load-bearing capacity of the bracket nut, ensuring that it can remain stable during the height adjustment process.

[0018] By setting up the through hole, the through hole has at least two functions. One is to facilitate the insertion of the torsion rod, which drives the support nut to rotate by inserting the torsion rod into the through hole; the other is to insert pins or bolts to fix the bracket nut with other components (such as the honing rod, diagonal rod, etc. in the formwork support system), thereby increasing the stability of the entire structure.

[0019] Furthermore, it also includes a first tray, which is detachably mounted on the adjusting column.

[0020] Furthermore, the end of each torsion rod can be inserted into or pulled out of the corresponding one of the through holes.

[0021] According to the above technical solution, when the torsion bar needs to be connected to the supporting nut, the end of the torsion bar can be aligned with the through hole on the supporting nut, and the end of the torsion bar can be inserted into the through hole by applying appropriate thrust until the torsion bar is firmly connected to the nut. This design makes the installation of the torsion bar simple and quick, while ensuring the stability and reliability of the connection.

[0022] Furthermore, it also includes a column and a second tray, one end of the adjusting column is connected to the second tray, and the other end of the adjusting column extends into the column and is threadedly connected to the column; when the adjusting column is rotated, the second tray can be driven to rise or fall along the axial direction of the column.

[0023] According to the above technical solution, one end of the adjusting column is connected to the second pallet, and the other end extends into the column and is threadedly connected to the column. The column serves as the main supporting structure and remains fixed to provide a stable supporting foundation. When the height of the second pallet needs to be adjusted, it can be achieved by rotating the adjusting column. Rotating the adjusting column will cause the adjusting column to rise or fall in the column. The second pallet serves as a bearing platform to support building materials such as wooden molds and steel pipes, thereby facilitating the erection of floor slabs.

[0024] Furthermore, the driving frame further comprises at least one stabilizing member, wherein the stabilizing member is disposed between the torsion bars, and each of the torsion bars is fixedly connected to the stabilizing member.

[0025] According to the above technical solution, the stabilizing member is arranged between each torsion bar, and the torsion bars are tightly connected together through fixed connection, which can effectively enhance the stability of the entire formwork support system and prevent the torsion bars from unexpected movement or deformation during use; when the formwork support system is subjected to external loads, the stabilizing member can help disperse the stress and avoid stress concentration that causes damage to the torsion bars, thereby ensuring the load-bearing capacity and durability of the entire drive frame.

[0026] Furthermore, it also includes a rib plate, which is fixed to the connection position between the second tray and the adjustment column.

[0027] According to the above technical solution, the ribs are fixedly connected to the connection position between the second pallet and the adjusting column, which can effectively enhance the structural strength of the connection. When the second pallet is carrying heavy objects or is subjected to external forces, the ribs can provide additional support to prevent the connection from breaking or deforming; at the same time, it also helps to disperse the load on the second pallet, thereby reducing the pressure on a single connection point and improving the bearing capacity of the entire structure.

[0028] Beneficial effects of the utility model:

[0029] The utility model is connected to the adjusting column by threading the bracket nut, then the torsion bar on the driving frame is aligned with the bracket nut and the torsion bar is connected with the bracket nut, and the electric driving part is engaged with the driving frame; when in use, the electric driving part is controlled to drive the torsion bar to rotate, and the bracket nut will be electrically rotated. When the bracket nut is rotated, it will rise or fall along the axial direction of the adjusting column, so as to quickly adjust the support height. The utility model has a compact structure, a simple and easy to use method, and is easy to operate. The screwing depth of the adjusting nut can be quickly controlled, which saves time and labor, and can quickly complete the installation of the bracket nut, thereby improving work efficiency.

[0030] The positioning rod of the utility model is located inside the adjusting column and can effectively play a limiting role. When the electric drive component drives the driving frame to rotate, the positioning rod can prevent the driving frame from separating from the adjusting column, which is convenient for the staff to operate.

When installing the bracket nut 2, the end of each torsion bar 33 can be inserted into or pulled out of the corresponding through hole 221. When it is necessary to connect the torsion bar 33 with the supporting nut, the end of the torsion bar 33 can be aligned with the through hole 221 on the supporting nut, and the end of the torsion bar 33 can be inserted into the through hole 221 by applying appropriate thrust until the torsion bar 33 is firmly connected to the nut.
