Description

Technical Field

[0001] This utility model relates to the field of marine flexible hose manufacturing technology, and in particular to a special-shaped steel belt traction device. Background Technology

[0002] In the field of marine engineering, flexible hoses play an irreplaceable role. To prevent pipelines from bursting due to excessive internal pressure, flexible hoses have a pressure-bearing layer inside. Their structure is typically a shaped steel strip structure; through interlocking, the steel strips can evenly distribute pressure, improving the overall pressure resistance of the hose.

[0003] During the winding process of shaped steel strips, traction equipment is needed to synchronously feed the symmetrical strips in a timely manner to ensure that the formed tube diameter meets the process requirements. Existing traction equipment uses pressure rollers to provide clamping force and pull the steel strip. However, the clamping force of the pressure rollers is provided by a hydraulic or pneumatic system, relying on an external oil pump or air compressor. This results in a slow response time, and the shaped steel strip may shift due to inertia during emergency braking or acceleration of the transmission system. Secondly, it is difficult to provide a stable clamping force output when pressure is applied, especially since the surface of the shaped steel strip is irregular, and vibration or speed changes during traction can easily cause material slippage or displacement. Furthermore, the reliability of hydraulic and pneumatic systems is relatively low, requiring regular inspection and maintenance, which affects production efficiency. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the pressure output system of the special-shaped steel belt traction device in the prior art, which has low reliability, unstable output pressure value, and affects product quality and production efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-3 As shown, this utility model discloses a special-shaped steel belt traction device, comprising:

[0029] A traction frame 1, on which a traction wheel 2 is provided;

[0030] A mechanical spring cylinder 3 includes a cylinder body 31, a lead screw 32, an elastic element 33, and a connecting shaft 34. One end of the lead screw 32 is inserted into the cylinder body 31, and the other end of the lead screw 32 is fitted with an adjusting nut 35. A sliding block 36 is provided inside the cylinder body 31 and is fitted outside the lead screw 32. One end of the connecting shaft 34 is inserted into the cylinder body 31 and connected to the lead screw 32. The elastic element 33 is disposed between the sliding block 36 and the connecting shaft 34. A pressure wheel 4 is provided at the other end of the connecting shaft 34, and the pressure wheel 4 abuts against the traction wheel 2.

[0031] In this invention, the clamping assembly generates clamping force through a mechanical spring cylinder 3, which outputs the force to the clamping wheel 4. The clamping wheel 4 presses against the traction wheel 2, and a shaped steel belt passes between the clamping wheel 4 and the traction wheel 2. Specifically, the entire mechanical spring cylinder 3 includes a lead screw shaft 32, an elastic element 33, and a connecting shaft 34. The lead screw shaft 32 and the connecting shaft 34 are respectively located at both ends of the cylinder body 31 and are connected inside the cylinder body 31. A sliding block 36 is sleeved on the outside of the lead screw and is fixedly connected to the lead screw shaft 32. Rotating the adjusting nut 35 causes the lead screw shaft 32 to move, while the sliding block 36 moves up and down inside the cylinder body 31. The elastic element 33 is located between the sliding block 36 and the connecting shaft 34. The movement of the sliding block 36 can adjust the tension of the elastic element 33, and the elastic element 33 applies clamping force to the connecting shaft 34. As a preferred embodiment of this utility model, the elastic element 33 is a disc spring. During assembly, the disc spring is sleeved on the outside of the lead screw shaft 32, and then the lead screw shaft 32 is connected to the connecting shaft 34. Secondly, the mechanical spring cylinder 3 in this utility model is provided in multiple sets, and correspondingly, multiple sets of drive wheels are provided, and multiple sets of traction wheels 2 are arranged along the length direction of the traction machine.

[0032] The elastic deformation of the elastic element 33 provides the clamping force, and its displacement characteristics are linear or approximately constant within a certain range, which can continuously maintain stable clamping on the irregular steel. This characteristic is particularly suitable for irregular steel surfaces, and can effectively prevent material slippage or displacement caused by vibration or speed changes during traction. The mechanical spring cylinder 3 structure in this utility model does not require an external power source, has high reliability, and does not require regular maintenance, thus improving production efficiency.

[0033] Furthermore, referring to Figure 3 As shown, a support base 37 is provided at the end of the connecting shaft 34 away from the lead screw shaft 32, and a wheel axle 38 is provided inside the support base 37. The pressing wheel 4 is sleeved on the wheel axle 38.

[0034] The support base 37 is used to install the support wheel. Specifically, a wheel axle 38 is inserted through the support base 37, and the pressure wheel 4 is sleeved on the wheel axle 38, with the pressure wheel 4 rotatably connected to the wheel axle 38. Preferably, in order to ensure the smooth rotation of the pressure wheel 4, a bearing is provided between the wheel axle 38 and the pressure wheel 4.

[0035] Furthermore, referring to Figure 2 As shown, a pressure sensor 39 is installed inside the connecting shaft 34.

[0036] Specifically, the pressure applied by the mechanical spring cylinder 3 is transmitted to the pressure roller 4 through the connecting shaft 34, and the pressure of the mechanical spring cylinder 3 can be detected by the pressure sensor 39. In actual operation, the pressure of the mechanical spring cylinder 3 can be adjusted according to the value fed back by the pressure sensor 39 to ensure that the pressure values ​​of multiple sets of mechanical spring cylinders 3 are the same, thereby ensuring that the traction pressure on the entire shaped steel belt is the same.

[0037] Furthermore, an oil filler port 313 is provided on the side wall of the cylinder body 31 near the end of the connecting shaft 34.

[0038] Specifically, when adjusting the pressure of the mechanical spring cylinder 3, the connecting shaft 34 moves inside the cylinder body 31. By adding lubricating oil at the oil filler port 313, the friction between the connecting shaft 34 and the cylinder body 31 can be reduced, the wear of the connecting shaft 34 can be reduced, and the service life of the entire mechanical spring cylinder 3 can be extended.

[0039] Furthermore, a first end cap 311 is provided at one end of the cylinder body 31 near the lead screw shaft 32, the lead screw shaft 32 passes through the first end cap 311, and the adjusting nut 35 abuts against the first end cap 311.

[0040] Specifically, on the one hand, the first end cover 311 can seal the inside of the cylinder body 31, and on the other hand, the first end cover 311 can support the adjusting nut 35. When the adjusting nut 35 is rotated, a reaction force can be applied to the lead screw shaft 32, which will drive the lead screw to rise and fall.

[0041] Furthermore, a second end cap 312 is provided at one end of the cylinder body 31 near the connecting shaft 34, the connecting shaft 34 passes through the second end cap 312, and a limiting platform 341 is provided on the surface of the connecting shaft 34.

[0042] Similarly, the other end of the cylinder body 31 can be sealed by the second end cover 312. Secondly, the second end cover 312 can also limit the movement of the connecting shaft 34. The limiting platform 341 abuts against the second end cover 312 to prevent the connecting shaft 34 from over-extending, while also ensuring the integrity of the entire mechanical spring cylinder 3.

[0043] Furthermore, the traction wheel 2 has a circumferential groove 21 on its surface.

[0044] Specifically, during the actual traction process, the shaped steel belt is input from the input end of the traction frame 1 and enters between the clamping wheel 4 and the traction wheel 2. The clamping wheel 4 is a flat wheel, and the surface of the traction wheel 2 is provided with a wheel groove 21. During the traction process, the shaped steel belt can be stuck in the wheel groove 21 to prevent the steel belt from shifting position.

[0045] Furthermore, referring to Figure 1 and Figure 6 As shown, the input and output ends of the traction frame 1 are each provided with at least one set of guide wheel groups 5. The guide wheel group 5 includes a first guide wheel 51 and a second guide wheel 52. The first guide wheel 51 and the second guide wheel 52 are both connected to the traction frame 1. The first guide wheel 51 is disposed on the top of the second guide wheel 52, and the surface of the second guide wheel 52 is provided with a wheel groove 21.

[0046] Specifically, the guide wheel assembly 5, positioned between the input and output ends of the traction frame 1, with its height flush with the contact point between the pressure wheel 4 and the traction wheel 2, guides the direction of the steel strip, facilitating its entry into the subsequent traction wheel 2 and pressure wheel 4. The guide wheel assembly 5 includes a first guide wheel 51 and a second guide wheel 52 positioned vertically. The first guide wheel 51 presses the shaped steel strip against the second guide wheel 52. Similarly, the surface of the second guide wheel 52, located at the bottom, has grooves to limit the radial displacement of the shaped steel strip, preventing positional deviation.

[0047] Furthermore, referring to Figures 4-5 The traction wheel 2 is provided with a drive shaft 6, and a drive gear 7 is sleeved on the drive shaft 6; the traction frame 1 is provided with a drive gear 8, and the drive gear 8 meshes with the drive gear 7.

[0048] Specifically, the traction wheel 2 and the transmission gear 7 rotate synchronously with the transmission shaft 6, the drive gear 8 meshes with the transmission gear 7, the drive gear 8 drives the transmission gear 7 to rotate, and in turn drives the traction wheel 2 to rotate.

[0049] Furthermore, a drive source 9 is provided on the traction frame 1, and a gearbox 10 is provided at the output end of the drive source 9, which meshes with the drive gear 8.

[0050] Specifically, the drive source 9 provides output power to drive the gearbox 10 to rotate. The gearbox 10 meshes with the drive gear 8, driving the drive gear 8 to rotate. In addition, the drive gear 8 in this invention meshes with two of the drive gears, and the remaining multiple traction wheels 2 are driven by the driven gears 11. The multiple drive wheels rotate synchronously to ensure the process requirements of the special-shaped steel are met.

[0051] In summary, this utility model introduces a traction device for irregularly shaped steel strips. The elastic deformation of the elastic element 33 provides the clamping force, and its displacement characteristics are linear or approximately constant within a certain range, continuously maintaining stable clamping of the irregularly shaped steel. This characteristic is particularly suitable for irregularly shaped steel surfaces, effectively preventing material slippage or displacement due to vibration or speed changes during traction. Secondly, the mechanical spring cylinder 3 structure in this utility model does not require an external power source, ensuring high reliability and eliminating the need for regular maintenance, thus improving production efficiency. Unlike hydraulic or pneumatic systems, the mechanical spring cylinder 3 does not rely on external oil pumps or air compressors, avoiding the risk of failure due to energy interruptions. It can still operate reliably under conditions of unstable power supply or harsh environments (such as dusty or high-temperature conditions). Furthermore, the response speed (millisecond level) of the mechanical spring cylinder 3 in this utility model far exceeds the oil compression delay of hydraulic systems, enabling real-time adaptation to sudden changes in traction speed. For example, during emergency braking or acceleration of the transmission system, the spring cylinder can quickly adjust the clamping force, preventing the irregularly shaped steel from shifting position due to inertia.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
