Description

Technical Field

[0001] The utility model relates to a detachable clamping type attachment, belonging to the technical field of cargo transfer equipment. Background Art

[0002] In the pulp and paper roll production process, limited equipment resources often strain on on-site equipment when both pulp and paper rolls are in place simultaneously. Currently, traditional vertical clamps cannot directly adapt to cylindrical paper roll sizes, requiring specialized paper roll clamps. These clamps cost over 300,000 yuan each, making replacement and maintenance cumbersome and complex. Therefore, improving existing vertical clamps to adapt to a wider range of operational needs has become a pressing issue.

[0003] Utility model patent application number CN201120025835.4 discloses a roller-type fork tine for forklifts handling cylindrical objects. The fork tine comprises a central shaft with a stopper protrusion at one end and a sleeve that is rotatably mounted on the central shaft. The other end is fixedly mounted on the forklift's lifting beam. The sleeve is coated with a rubber layer on the outer wall. The sleeve is detachably mounted on the central shaft. Both tines are detachably mounted on the forklift's lifting beam. Compared to the flat tines of traditional forklifts, the roller-type fork tine has a sleeve that is rotatable around the central shaft. During loading, unloading, and transport of the culvert, when the culvert and the tines slide relative to each other, the sleeve also rotates with the culvert rather than sliding against it. This prevents damage to the electroplated anti-corrosion coating caused by the sliding friction between the culvert and the tines, thus ensuring the construction quality and service life of the culvert. Fork-type cylindrical object handling tools are not suitable for handling vertically placed cylindrical objects. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the prior art of cumbersome handling of vertically placed cylindrical objects and high equipment costs, and to provide a detachable clamping attachment.

[0005] The utility model is realized through the following technical solutions:

[0006] That is, a detachable clamping attachment, comprising a base plate mounted on a forklift and two left and right clamping mechanisms, with four slide rails fixed on the base plate;

[0007] The clamping mechanism includes a side plate and a hydraulic cylinder. Two strip plates are fixed on the inner end of the side plate. The strip plates are slidably installed on the slide rails. One end of the hydraulic cylinder is connected to the inner end of the side plate, and the other end of the hydraulic cylinder is connected to the bottom plate. An arc plate is installed on the inner side of the side plate.

[0008] The utility model is installed similarly to a fork knife being loaded into a tool magazine. It is mounted on a forklift and locked with a reinforcement device, ensuring the safety and firmness of the attachment during use. This solves the problem of equipment shortage in on-site operations, allowing the straight-hold clamping device to simultaneously adapt to the needs of handling cylindrical objects such as pulp and paper rolls, thereby improving equipment utilization and efficiency, and providing convenient operation and low cost.

[0009] Further preferably, two strip holes are provided on the side panel, a hinge support is provided on the outer side of the side panel, a pressure plate is provided on the inner side of the side panel, and two sets of bolts and nuts are passed through the strip holes to install the pressure plate and the hinge support on both sides of the side panel;

[0010] Further preferably, two first through-tubes are fixedly provided on the inner side of the hinge support, and two second through-tubes are fixedly provided on the outer side of the curved plate. The first through-tubes extend from the outer side of the strip hole to the inner side of the strip hole, and a pin is passed through the first and second through-tubes. The curved plate can be moved forward and backward according to the on-site usage environment, and the curved plate can be easily assembled and disassembled. At the same time, the curved plate can be rotated around the pin, which makes it easy to clamp cylindrical objects and helps improve handling efficiency.

[0011] Further preferably, a limit block is sleeved on the bolt, and the limit block is located in the strip hole. The limit block plays a limiting role to prevent the hinge support and the arc plate from rotating.

[0012] More preferably, a pull ring is fixedly provided on the top end of the pin shaft. Holding the pull ring makes it more convenient to disassemble and assemble the pin shaft.

[0013] Further preferably, the cross-section of the slide rail is T-shaped, and the strip plate is provided with a T-shaped slide groove that is compatible with the T-shaped slide rail.

[0014] Further preferably, the inner surface of the curved plate is provided with anti-slip grooves.

[0016] The utility model is installed similarly to a fork knife being loaded into a tool magazine. It is mounted on a forklift and locked with a reinforcement device, ensuring the safety and firmness of the attachment during use. This solves the problem of equipment shortage in on-site operations, allowing the straight-hold clamping device to simultaneously adapt to the needs of handling cylindrical objects such as pulp and paper rolls, thereby improving equipment utilization and efficiency, and providing convenient operation and low cost.
