Description

Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to a screen drum clamping and conveying device. Background Technology

[0002] Screen drums are widely used in the papermaking and wastewater treatment industries. They are used in the papermaking industry to separate impurities from pulp to improve pulp quality, or in the wastewater treatment industry to separate solids from wastewater to improve wastewater cleanliness. Their structure mainly consists of upper and lower flanges, bars, and retaining rings.

[0003] During the processing of the screen drum, it needs to be transported to the corresponding equipment for processing. For example, after the bars are installed on the upper and lower flanges, it needs to be moved to the welding equipment to weld and fix the bars to other components. Since the screen drum is large in size and weight, it is usually transported by forklift or crane.

[0004] However, this type of transportation requires workers to manually fix the screen drum, which is cumbersome. Moreover, the screen drum is prone to deformation during transportation, affecting subsequent processing and resulting in low transportation efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a screen drum clamping and conveying device to solve the problem of difficulty in quickly clamping and conveying the screen drum to the corresponding work station for processing in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a screen drum clamping and conveying device, including a frame, a base mounted on the frame, a lifting mechanism slidably connected to the base in a vertical direction for lifting workpieces, and a clamping mechanism mounted on the movable end of the lifting mechanism for clamping workpieces. The clamping mechanism includes two jaws that slide relative to each other in a horizontal direction, an abutment rod respectively mounted on each jaw that can abut against the side wall of the workpiece, and a driving component that can drive the jaws to move relative to each other. The jaws are also provided with an abutment component that can drive the abutment rod to move along the jaw's moving direction.

[0007] By adopting the above technical solution, the frame can be moved above the workpiece, the clamping mechanism can be moved to the upper end of the workpiece by the lifting mechanism, and the two grippers can be moved relative to each other by the drive component, thereby abutting against the side wall of the workpiece. The abutting component can also drive the abutting rod on the gripper to abut against and press against the side wall of the workpiece, thereby realizing secondary clamping of the workpiece, thus improving the clamping effect of the workpiece and ensuring that the workpiece is not easy to fall off during the movement. Then, the lifting mechanism lifts the workpiece and moves it to the required work position with the frame for processing. The operation is simple and convenient, and it is convenient for transporting the screen drum.

[0008] In one embodiment of the present invention, the gripper is configured as an L-shaped structure, the abutting rod is disposed at the short arm of the gripper, and the short arm of the gripper is also provided with a limiting groove that can abut against the side wall of the workpiece, and a flexible pad that can abut against the workpiece is disposed in the limiting groove.

[0009] By adopting the above technical solution, the limiting groove at the short arm of the gripper can be made to abut against the protruding edge of the upper and lower flanges of the screen drum, and then the abutting rod can be used to abut against and fix the side wall of the screen drum, so as to improve the clamping effect.

[0010] In one embodiment of the present invention, the abutment component includes a limiting ring disposed on the abutment rod and a spring sleeved on the limiting ring to elastically connect the limiting ring and the gripper.

[0011] By adopting the above technical solution, the spring, in conjunction with the limiting ring, enables the contact rod to elastically press against the side wall of the screen drum, resulting in a better pressing effect.

[0012] In one embodiment of the present invention, an abutment plate is provided at the other end of the abutment rod relative to the limiting ring. The abutment plate is configured as an L-shaped structure, and a flexible pad is wrapped around the outside of the abutment plate.

[0013] By adopting the above technical solution and using an L-shaped contact plate, when the screen drum axis is in a horizontal state for transverse transport, the contact rod can contact the inner wall of the screen drum, making its clamping and conveying range wider and enabling multiple conveying methods.

[0014] In one embodiment of the present invention, the lifting mechanism includes a support seat disposed on the lower side of the base, a connecting seat disposed below the support seat for connecting the clamping mechanism, and a pulley block connecting the support seat and the connecting seat and driving the connecting seat to move in the vertical direction, and also includes a limiting guide rod disposed on the connecting seat and connected to the pulley block.

[0015] By adopting the above technical solution, the clamping mechanism on the connecting seat can be moved by a pulley block, making it more stable when lifting and lowering. Moreover, the structure is simple and reliable, and the screen drum will not shake during the movement of the frame by the limit guide rod.

[0016] In one embodiment of the present invention, the frame includes two support rods arranged parallel to each other in the vertical direction, a crossbar arranged at the upper end of the two support rods, and a base plate arranged at the bottom of the two support rods and perpendicular to the crossbar. The support rods are also provided with inclined bracing rods on both sides to strengthen the support strength of the support rods. The base is provided with a moving component that can drive the base plate to move.

[0017] By adopting the above technical solutions, the frame structure becomes simpler and lighter, easier to process, and provides reliable support.

[0018] In one embodiment of the present invention, a groove is provided on the crossbar along its extension direction, the base is slidably connected to the groove, and the base is provided with a horizontal displacement mechanism that can drive the base to move along the groove. The horizontal displacement mechanism includes a roller disposed in the groove and capable of moving along the extension direction of the groove, a connecting frame connecting the roller and the base, and a drive motor disposed on the connecting frame to drive the roller to rotate.

[0019] By adopting the above technical solution, the screen drum can be moved horizontally along the crossbar after being lifted by the lifting mechanism. This allows for small-range movement of the workpiece without moving the frame, making the lifting and transportation of the workpiece more convenient.

[0020] In one embodiment of this utility model, two sliding grooves are provided, respectively on both sides of the crossbar, and two rollers are provided accordingly, with the connecting frame rotatably connecting the two rollers.

[0021] By adopting the above technical solution, the connecting frame can be subjected to more uniform force and its movement can be more stable and reliable.

[0022] In one embodiment of the present invention, the moving component includes a plurality of omnidirectional brake wheel sets respectively disposed on two bottom lower sides.

[0023] By adopting the above technical solution, the frame can be moved to the required position and then fixed by the universal brake wheel set.

[0024] As described above, the screen drum clamping and conveying device of this utility model has the following beneficial effects: it can move the frame above the workpiece, move the clamping mechanism to the upper end of the workpiece through the lifting mechanism, and drive the two jaws to move relative to each other through the drive component, thereby abutting against the side wall of the workpiece. It can also drive the abutting rod on the jaw to abut against and press against the side wall of the workpiece by the abutting component, thereby realizing secondary clamping of the workpiece, thereby improving the clamping effect of the workpiece and ensuring that the workpiece is not easy to fall off during the movement. Then, the lifting mechanism lifts the workpiece and moves it to the required work position with the frame for processing. The operation is simple and convenient, and it is convenient for transporting the screen drum. Attached Figure Description
