Description

Technical Field

[0001] This invention relates to the field of tensioning mechanism technology, specifically to a highly stable tensioning machine suspension balancing device. Background Technology

[0002] Lengthening a cylindrical workpiece increases its strength, but generally reduces its plasticity. If the requirements for the cylindrical workpiece are not high, tensioning can be saved. Prestressed cylindrical workpieces require tensioning to generate prestress, which does not increase strength but can reduce cracking. A cylinder-suspended tensioning mechanism suspends the workpiece and uses tensioning ropes to tension it.

[0003] Currently, the tensioning cylinders of existing tensioning machines on the market are generally installed on vertical guide rails on the frame. The vertical position of the tensioning cylinder is adjusted by a nut and screw mechanism. This type of tensioning machine only has two degrees of freedom in the vertical direction, and the mechanism has high rigidity. It requires high positional accuracy of the equipment itself and the guide rail. In actual use, due to the extremely harsh working conditions at the pipe pile production site, both the tensioning machine and the tensioned pipe mold may have large positional errors, which can easily cause eccentric tensioning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a highly stable tensioning machine suspension balancing device, which solves the problem that the extremely harsh working conditions at the pipe pile production site can cause large positional errors in both the tensioning machine and the tensioned pipe mold, easily leading to eccentric tensioning.

[0007] Preferably, the gear shaft of the main gear three is fixedly connected to the top of the inner sidewall of the linkage bearing, and the main fixing frame is rotatably connected to the main gear three through the linkage bearing.

[0008] Preferably, the longitudinal drive assembly includes a longitudinal fixing frame, which is fixedly connected to the top of the main gear three. Two sets of longitudinally evenly arranged mounting bearings are fixedly connected to the left and right side walls of the longitudinal fixing frame. The lower two sets of mounting bearings are fixedly connected to a first linkage shaft. The left side of the first linkage shaft is fixedly connected to a secondary bevel gear, which meshes with a bevel gear rod. The right side of the first linkage shaft is fixedly connected to the main linkage gear. The upper two sets of mounting bearings are fixedly connected to a second linkage shaft.

[0009] Preferably, the bottom end of the polygonal sliding column is fixedly connected to a limiting sleeve, the main bearing extends longitudinally through the bottom wall of the main fixing frame and into the interior of the main fixing frame, and the screw extends longitudinally through the main bearing and into the drive cylinder and the main fixing frame respectively.

[0010] Preferably, the secondary bearing extends longitudinally through the top wall of the main fixing frame and extends to the interior and exterior of the main fixing frame, respectively.

[0011] Preferably, the bevel gear rod passes through the top wall of the main fixing frame and the bottom wall of the longitudinal fixing frame and extends into the interior of the longitudinal fixing frame.

[0012] Preferably, a second motor is fixedly connected to the rear side of the inner top wall of the main fixing frame. The top output shaft of the second motor longitudinally penetrates the top wall of the main fixing frame and is rotatably connected to the top wall of the main fixing frame. The top output shaft of the second motor is fixedly connected to a second auxiliary gear, and the third main gear meshes with the second auxiliary gear.

[0013] Preferably, the longitudinal fixing frame is rotatably connected to the second linkage shaft via two sets of mounting bearings, and the longitudinal fixing frame is rotatably connected to the first linkage shaft via two sets of mounting bearings.

[0014] Preferably, the right side of the linkage shaft two is fixedly connected to the secondary gear four, the bottom end of the secondary gear four is meshed with the linkage main gear, the middle part of the linkage shaft two is fixedly connected to the linkage seat, and the top of the linkage seat is fixedly connected to the suspension hanger.

[0015] Working Principle: First, the device is welded to the desired work position using a limiting sleeve installed at the bottom of the polygonal sliding column. Based on the optimal working distance for different spaces, the first motor is started. Motor one drives the auxiliary gear one installed on its output shaft to rotate. The main gear one, meshing with the auxiliary gear one, drives the screw to rotate within the polygonal groove inside the drive cylinder via the main bearing. After the screw is driven to rotate, the polygonal sliding column, which has an internal thread groove and is threaded to the screw, moves up and down inside the drive cylinder due to its shape and the shape characteristics of the polygonal groove. This drives the lateral drive assembly to lift and lower, thus enabling the device to automatically adjust to different working distances and improve work efficiency. Once the distance is adjusted, the second motor installed inside the main fixed frame is started. Motor two drives the auxiliary gear two installed on its top output shaft. After rotation, the main gear three, meshing with the secondary gear two, drives the longitudinal fixed frame equipped with the suspension components to rotate 36 degrees laterally. Simultaneously, the suspension components are activated to suspend and lift the tensioning machine. Then, by starting motor three, the secondary gear three mounted on the top output shaft of motor three drives the meshing main gear two to rotate. This causes the bevel gear rod fixed at the top of the main gear two to rotate using the secondary bearing. The bevel gear rod then drives the meshing secondary bevel gear and the linkage shaft one fixed to the secondary bevel gear to rotate. The linkage main gear mounted on the other side of linkage shaft one rotates accordingly. The secondary gear four, meshing with the linkage main gear, drives the linkage shaft two, which has a fixed linkage seat, to begin rotating back and forth. The linkage seat also drives the suspension components to rotate automatically back and forth. Through automatic rotation back and forth and left and right, the suspension achieves the effect of automatically adjusting the horizontal plane and maintaining balance while suspending the equipment.

[0016] This invention provides a highly stable suspension balancing device for a tensioning machine. It has the following beneficial effects: 1. This invention activates an additional motor based on the optimal working distance for different spaces. The motor drives a secondary gear on its output shaft to rotate, and the main gear meshing with the secondary gear drives a screw to rotate within a polygonal groove inside the drive cylinder via a main bearing. After the screw is driven to rotate, the polygonal slide column with an internal threaded groove and threaded connection to the screw moves up and down inside the drive cylinder due to its shape and the shape characteristics of the polygonal slide groove. This drives the lateral drive assembly to lift and lower, thereby enabling the device to automatically adjust to different working distances and improve the working efficiency.

[0017] 2. This invention activates a second motor installed inside the main fixed frame. The second motor drives a second auxiliary gear installed on its top output shaft to rotate. The third main gear, meshing with the second auxiliary gear, drives the longitudinal fixed frame, which is equipped with the suspension components, to rotate 36 degrees laterally. Simultaneously, the suspension components are activated to suspend and hoist the tensioning machine. Activating the third motor again causes the second auxiliary gear installed on its top output shaft to drive the meshing main gear 2 to rotate. This causes the bevel gear rod fixed at the top of the main gear 2 to rotate using a secondary bearing. The bevel gear rod then drives the meshing secondary bevel gear and the linkage shaft 1 fixed to the secondary bevel gear to rotate. The linkage main gear installed on the other side of the linkage shaft 1 rotates accordingly. The fourth auxiliary gear meshing with the linkage main gear drives the linkage shaft 2, which has a fixed linkage seat, to start rotating back and forth. The linkage seat also drives the suspension components to rotate automatically back and forth. Through automatic rotation back and forth and left and right, the suspension is simultaneously suspended and automatically adjusted to maintain horizontal level and achieve balance.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: like Figure 1 As shown, this embodiment of the invention provides a highly stable tensioning machine suspension balancing device, including a distance conversion component 1 and a lateral drive component 2, with the lateral drive component 2 disposed on the top of the distance conversion component 1.

[0022] like Figure 2 and Figure 3 As shown, the distance conversion component 1 includes a main bearing 11, a drive cylinder 12, a motor 13, a secondary gear 14, a main gear 15, a screw 16, a polygonal groove 17, a polygonal sliding column 18, and an internal thread groove 19. The main bearing 11 is fixedly connected to the center of the bottom wall of the main fixing frame 21. The drive cylinder 12 is fixedly connected to the bottom of the main bearing 11.

The screw 16 is threaded into the internal thread groove 19. The bottom end of the polygonal sliding column 18 is fixedly connected to a limiting sleeve 110. The main bearing 11 is longitudinally connected to the drive cylinder 12. The screw 16 extends longitudinally through the main bearing 11 and into the drive cylinder 12 and the main fixed frame 21, penetrating the bottom wall of the main fixed frame 21 and extending into the main fixed frame 21. First, the device is welded to the position where the work needs to be carried out using the limiting sleeve 110 installed at the bottom of the polygonal slide column 18. According to the optimal working distance of different spaces, the installed motor 13 is started. The motor 13 drives the auxiliary gear 14 installed on its output shaft to rotate. The main gear 15, which meshes with the auxiliary gear 14, drives the screw 16 to rotate in the polygonal slide groove 17 set inside the drive cylinder 12 through the main bearing 11. After the screw 16 is driven to rotate, the polygonal slide column 18, which is fitted with an internal thread groove 19 and threaded to the screw 16, moves up and down inside the drive cylinder 12 due to its own shape characteristics and the polygonal slide groove 17. This drives the transverse drive component 2 to lift and lower, thereby enabling the device to automatically adjust different working distances and improve the working effect.

The third auxiliary gear 26 is fixedly connected to the top output end of the third motor 24, and the third auxiliary gear 26 meshes with the second main gear 25. The linkage bearing 210 is fixedly connected to the top of the secondary bearing 27. The gear shaft of the main gear 28 is fixedly connected to the top of the inner wall of the bearing 210. The main fixed frame 21 is rotatably connected to the main gear 28 through the linkage bearing 210.

The top output shaft of the motor 22 is fixedly connected to the secondary gear 23. The main gear 28 meshes with the secondary gear 23. The secondary bearing 27 longitudinally penetrates the top wall of the main fixed frame 21 and extends to the inside and outside of the main fixed frame 21 respectively. After the distance is adjusted, the motor 22 installed inside the main fixed frame 21 is started. The motor 22 drives the secondary gear 23 installed on its top output shaft to rotate.

[0024] like Figure 5 and Figure 6As shown, the longitudinal drive assembly 3 includes a fixed frame 31. The top of the main gear 28 is fixedly connected to the longitudinal fixed frame 31.

The longitudinal fixed frame 31 is rotatably connected to the second connecting shaft 36 via two sets of mounting bearings 32. Two sets of mounting bearings 32 are rotatably connected to the linkage shaft 33. The main gear 28, which meshes with the secondary gear 23, drives the longitudinal fixing frame 31, which is equipped with the suspension component 39, to rotate 36 degrees laterally. Simultaneously, the suspension component 39 is activated to suspend and lift the tensioning machine. Then, by starting the motor 24, the secondary gear 26 mounted on the top output shaft of the motor 24 drives the meshing main gear 25 to rotate.
