Description

Technical Field

[0001] This utility model relates to the field of tilting lifting equipment technology, and in particular to a clamping mechanism and a tilting lifting equipment. Background Technology

[0002] Open wagons are a type of railway freight car characterized by their open top and side panels on all four sides. They are primarily used for transporting bulk goods such as coal or ore. Currently, to reduce pollution, coal or ore is first placed in containers, and then the containers are loaded into open wagons for transport. Patent application number 202210949446.3 discloses a lifting device and a method for unloading containers. The lifting device includes a lifting mechanism, which comprises a mounting frame, a tilting frame, and a lifting assembly. The lifting assembly includes a lifting drive unit and a lifting unit driven by the lifting drive unit. The lifting drive unit can drive the lifting unit to lift and lower, so that the center of gravity of the object lifted by the lifting unit is close to the rotation axis of the tilting frame. When the lifting unit is connected to the container, misalignment is prone to occur, or the locking mechanism of the lifting unit cannot be fully inserted into the container's locking hole, requiring additional manual intervention. This results in low unloading efficiency, cumbersome operation, and high costs. Utility Model Content

[0022] Please see Figure 1 , Figure 2 and Figure 3 A clamping mechanism according to an embodiment of the present invention is installed on a tilting frame 200. A lifting device 210 is slidably connected to the tilting frame 200, and the lifting device 210 is square in shape. The clamping mechanism includes multiple clamping components 100, which are respectively installed on the tilting frame 200 at the corner positions corresponding to the lifting device 210. Each clamping component 100 includes a pressure rod 110 and a clamping drive component 120. The middle part of the pressure rod 110 is hinged to the tilting frame 200, and the clamping drive component 120 is installed on the tilting frame 200. The clamping drive component 120 is hinged to one end of the pressure rod 110, and is used to drive one end of the pressure rod 110 to rotate around the hinge point between the pressure rod 110 and the tilting frame 200, so that the other end of the pressure rod 110 can clamp the lifting device 210.

[0023] The spreader 210 lifts the container, and the clamping drive assembly 120 drives one end of the pressure rod 110 to rotate, so that the other end of the pressure rod 110 clamps the spreader 210. Multiple clamping assemblies 100 are respectively installed on the tilting frame 200 corresponding to the corner positions of the spreader 210. Multiple clamping drive assemblies 120 work simultaneously, so that multiple pressure rods 110 clamp the spreader 210 at the same time, ensuring that the spreader 210 is subjected to uniform pressure, ensuring that the spreader 210 is smoothly connected to the container, reducing manual intervention, improving unloading efficiency, simplifying operation, and saving costs.

[0024] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The clamping drive assembly 120 includes a clamping drive cylinder. One end of the clamping drive cylinder is hinged to the tilting frame 200, and the other end is hinged to one end of the pressure rod 110. The piston movement of the clamping drive cylinder drives the pressure rod 110 to perform precise rotational movement, ensuring that the other end of the pressure rod 110 can accurately clamp the lifting device 210. The clamping drive cylinder has a fast response speed; the piston movement speed of the clamping drive cylinder can reach several meters per second. This rapid response characteristic allows the device to complete the clamping and release of the workpiece in a short time, significantly improving production efficiency.

[0025] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The other end of the pressure bar 110 is hinged to a pressure block 130, and the pressure block 130 has a flat surface underneath. By setting the pressure block 130 and having a flat surface underneath, the contact area between the pressure block 130 and the spreader 210 can be increased, ensuring that the pressure of the pressure bar 110 is evenly applied to the spreader 210, and ensuring that the spreader 210 is smoothly connected to the container.

[0026] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pressure block 130 includes two first clamping plates 131 and a pressure plate 132. The two first clamping plates 131 are respectively hinged to both sides of the pressure rod 110 via hinge shafts. The pressure plate 132 is connected below the two first clamping plates 131, and has a flat surface below it. The pressure block 130 is welded together from the two first clamping plates 131 and the pressure plate 132, resulting in a simple structure. The pressure block 130 is hinged to the pressure rod 110. During the rotation of the pressure rod 110 around the hinge point between the pressure rod 110 and the tilting frame 200, the pressure plate 132 remains below the two first clamping plates 131 due to gravity.

[0027] In some embodiments, see Figure 1 , Figure 2 and Figure 3A support base 140 is provided on the tilting frame 200, and the middle part of the pressure rod 110 is hinged to the support base 140. The support base 140 protrudes from the tilting frame 200, providing a fulcrum for the pressure rod 110. Using the lever principle, it ensures that the pressure rod 110 can press the lifting device 210.

[0028] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The support base 140 includes two second clamping plates 141 and a support plate 142. The two second clamping plates 141 are hinged to both sides of the pressure rod 110 via hinge shafts. The support plate 142 is connected below the two second clamping plates 141 and is fixedly connected to the tilting frame 200. The two second clamping plates 141 are welded to the support plate 142, resulting in a stable structure. The two second clamping plates 141 clamp the pressure rod 110, limiting its lateral movement and improving the clamping accuracy of the clamping mechanism.

[0029] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The tilting frame 200 is provided with a mounting base 150, and one end of the clamping drive assembly 120 is hinged to the mounting base 150. The mounting base 150 includes two third clamping plates 151 and a mounting plate 152. The mounting plate 152 is mounted on the tilting frame 200, and the two third clamping plates 151 are welded to the mounting plate 152. One end of the clamping drive assembly 120 is hinged to the two third clamping plates 151 through a hinge shaft.

[0030] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pressure bar 110 includes a body portion 111 and a hinge portion 112, with the hinge portion 112 protruding and connected to the lower center of the body portion 111. The hinge portion 112 protruding and located at the lower center of the body portion 111 makes the pressure bar 110 have better overall strength and is not easy to break.

[0031] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pressure rod 110 has hinge holes at both ends, through which the hinge shaft passes. Both ends of the pressure rod 110 also have oil injection holes that connect to the hinge holes, and oil injection nozzles 113 are installed at these holes. Lubricant can be applied to the hinge shaft through the oil injection nozzles 113.

[0032] See Figure 1 , Figure 2 and Figure 3 A flipping lifting device according to an embodiment of this application includes a clamping mechanism.

[0033] The spreader 210 lifts the container, and the clamping drive assembly 120 drives one end of the pressure rod 110 to rotate, so that the other end of the pressure rod 110 clamps the spreader 210. Multiple clamping assemblies 100 are respectively installed on the tilting frame 200 corresponding to the corner positions of the spreader 210. Multiple clamping drive assemblies 120 work simultaneously, so that multiple pressure rods 110 clamp the spreader 210 at the same time, ensuring that the spreader 210 is subjected to uniform pressure, ensuring that the spreader 210 is smoothly connected to the container, reducing manual intervention, improving unloading efficiency, simplifying operation, and saving costs.

[0034] The working principle of the clamping mechanism in this application embodiment is as follows: When the tipping spreader moves above the open-top container, the lifting mechanism on the tipping frame 200 drives the spreader 210 to descend from the top of the tipping frame 200 to above the container. The container aligns with the spreader 210, the output end of the pressing drive cylinder extends, and the other end of the pressure rod 110 is pressed down. The other end of the pressure rod 110 drives the pressure block 130 to press on the spreader 210, and the lock on the spreader 210 is inserted into the lock hole of the container to complete the locking.

[0035] The output end of the pressure drive cylinder retracts, causing the other end of the pressure rod 110 to rise and move out of the movement range of the lifting device 210, thus avoiding interference with the lifting device 210.

[0036] The lifting mechanism on the tilting frame 200 drives the spreader 210 to rise to the predetermined position, and the tilting frame 200 tilts to tilt and unload the container.

[0037] After the container is tipped over and unloaded, the lifting mechanism on the tipping frame 200 lowers the spreader 210, placing the container back into the open wagon and unlocking it. After unlocking, the lifting mechanism on the tipping frame 200 resets the spreader 210, completing all actions.
