It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] 2. Example 1, as Figures 1-4 As shown, a fixed-length cutting mechanism for prestressed steel rods of a pipe pile comprises a steel rod positioning and adjusting mechanism 1, and a shearing adjustment mechanism 2 is fixedly connected to one side of an outer wall of the steel rod positioning and adjusting mechanism 1;

[0026] The steel rod positioning and adjustment mechanism 1 includes a support frame 101, a fixing plate 102 is fixedly connected to the top of the support frame 101 near the edge, a driving motor 103 is fixedly connected to one side of the outer wall of the fixing plate 102, a transmission shaft 104 is fixedly installed on the output end of the driving motor 103, and the outer wall of the transmission shaft 104 is movably inserted into the inner wall of the fixing plate 102, a first threaded hole 105 is provided on one side of the outer wall of the transmission shaft 104, a first bolt 106 is threadedly connected to the inner wall of the first threaded hole 105, a guide hub 107 is movably sleeved on the outer wall of the first bolt 106, and a plurality of second threaded holes 108 are provided on the outer wall of the guide hub 107. The inner wall of each second threaded hole 108 is threadedly connected to six second bolts 109, and a spliced ​​conveying disk 110 is movably sleeved between the outer walls of the six second bolts 109. Three bearings 111 are fixedly connected to one side of the outer wall of the fixed plate 102, and the inner walls of the three bearings 111 are fixedly connected to a connecting shaft 112, and the outer walls of the three connecting shafts 112 are movably inserted into the inner wall of the fixed plate 102. A third threaded hole 113 is opened on one side of the outer wall of the three connecting shafts 112, and the inner walls of the three third threaded holes 113 are threadedly connected to a third bolt 114, and the outer walls of the three third bolts 114 are movably sleeved with a conveying wheel 115.

[0027] The effect achieved by the entire embodiment 1 is that, under the action of the steel rod positioning and adjusting mechanism 1, a fixing plate 102 is fixedly connected to the top of the support frame 101 near the edge, and a driving motor 103 is fixedly connected to one side of the outer wall of the fixing plate 102. The output end of the driving motor 103 is fixedly installed with a transmission shaft 104. By starting the driving motor 103, the driving motor 103 smoothly drives the transmission shaft 104 fixedly installed at its output end to rotate, thereby driving the threaded connection between the first bolt 106 and the first threaded hole 105 to rotate the guide hub 107 movably sleeved on the outer wall of the first bolt 106. The steel rods are conveyed under the action of the spliced ​​conveyor disc 110, and the three conveyor discs 115 and the guide wheel hub 107 convey the steel rods forward in a jerky manner under the action of the driving motor 103. After each transmission of the length required for shearing, the transmission of the steel rods will be stopped due to the special shape design of the spliced ​​conveyor disc 110, so that workers can adjust the length of the spliced ​​conveyor disc 110 according to the required length of the steel rods to be sheared. Through this connection method, not only the steel rod shearing model range of the equipment is expanded, but also the rapid modification and adjustment of the steel rod shearing length is realized, thereby improving the efficiency of shearing steel rods, improving the shearing accuracy, and enhancing the utilization rate of materials.

[0028] Example 2, as Figure 2-Figure 4As shown, the shearing adjustment mechanism 2 includes a workbench 201, a shearing platform 202 is fixedly connected to the top of the workbench 201 near the center, two first hydraulic rods 203 are fixedly connected to the top of the shearing platform 202, an upper clamping block 204 is fixedly connected between the tops of the two first hydraulic rods 203, a lower clamping block 205 is fixedly connected to the top of the shearing platform 202, three stress springs 206 are fixedly connected to the top of the shearing platform 202 near the edge, a force plate 207 is fixedly connected between the tops of the three stress springs 206, a lower shearing block 208 is fixedly connected to the top of the force plate 207, two protective plates 209 are fixedly connected to the top of the shearing platform 202, a support plate column 210 is fixedly connected to the top of the workbench 201 near the edge, a second hydraulic rod 211 is fixedly connected to the bottom of the support plate column 210, an upper shearing block 212 is fixedly connected to the bottom of the second hydraulic rod 211, and one side of the outer wall of the support frame 101 is fixedly connected to one side of the outer wall of the workbench 201.

[0029] The effect achieved by the entire embodiment 2 is that, under the action of the shear adjustment mechanism 2, a shearing platform 202 is fixedly connected to the top of the workbench 201 near the center, and then two first hydraulic rods 203 are fixedly connected to the top of the shearing platform 202. By controlling the two first hydraulic rods 203, the upper clamping block 204 is driven to clamp the steel rod, and the upper shearing block 212 is controlled by the second hydraulic rod 211 to apply shear force to the steel rod. Three stress springs 206 are fixedly connected to the top of the shearing platform 202 near the edge, and a force plate 207 is fixedly connected between the tops of the three stress springs 206. The top of the force plate 207 is fixedly connected to the lower shearing block 208. Under the joint action of the lower shearing block 208 and the stress spring 206, the stability and stability of the mechanical device during movement are ensured, energy loss is reduced, the steel rod shearing efficiency is improved, and the steel rod shearing surface is made smoother and more beautiful.

[0030] Working principle: When in use, first place the steel rod to be sheared on the steel rod positioning and adjustment mechanism 1 of the equipment, and adjust and replace the guide hub 107, the spliced ​​conveyor disc 110, and the three conveyor discs 115 by rotating the thread according to the size and model of the steel rod and the length to be sheared. After preparation is completed, start the drive motor 103, so that the drive motor 103 can smoothly drive the transmission shaft 104 fixed on its output end to rotate, thereby driving the guide hub fixed by the first threaded hole 105 of the first bolt 106 to rotate, and at the same time, the steel rod is conveyed under the action of the spliced ​​conveyor disc 110. Under the action of the drive motor 103, the three conveyor discs 115 and the guide hub 107 convey the steel rod forward in a jerky manner. After each length required to be sheared is conveyed, the conveying of the steel rod will be stopped due to the special shape design of the spliced ​​conveyor disc 110. At the same time, the shearing adjustment mechanism 2 controls the two first hydraulic rods 203 to drive the upper clamping block 204 to clamp the steel rod, and controls the upper shear block through the second hydraulic rod 211 212 applies shear force to the steel rod, and at the same time, under the joint action of the lower shear block 208 and the stress spring 206, the smoothness and stability of the mechanical device during movement are ensured, and energy loss is reduced. After each shearing is completed, the two first hydraulic rods 203 control the upper clamping block 204 to stop clamping. At the same time, under the action of the guide hub 107 and the spliced ​​conveyor disc 110, no conveying force is applied to the steel rod when the steel rod is in the clamping state. When shearing another type of steel rod, we remove the first bolt 106 from the first threaded hole 105 by rotating the thread, and quickly replace the corresponding model of the guide hub 107 and the model of the three conveyor discs 115, and then cut the length of the steel rod as needed, replace and install the spliced ​​conveyor disc 110. In this way, not only the steel rod shearing model range of the equipment is expanded, but also the rapid modification and adjustment of the steel rod shearing length is realized, thereby improving the efficiency of shearing steel rods, improving the shearing accuracy, enhancing the utilization rate of materials, and enhancing the practicality and convenience of the device.
