Description

Technical Field

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

[0002] The emergence of clamp-on forks was precisely to meet the need for efficient and safe handling of various types of goods. They can better adapt to items of different shapes and packaging, such as drums, bags, and paper rolls. In paper mills, for example, paper rolls are large, heavy, and their surfaces need to be protected from scratches; clamp-on forks can grip the paper rolls from the side, avoiding damage that might be caused by the insertion of traditional forks.

[0003] Currently, one type of clamping fork in existing technology uses two clamps to grip the goods. However, for items with curved angles, the two clamps may slip and fall off when they move towards each other, which has significant limitations and poor practicality. In addition, the fork bodies of existing clamping forks are in a fixed position and cannot be retracted into the clamps according to actual needs, which may hinder gripping and further reduce practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology, which uses two clamps to clamp items. However, for items with curved angles, the two clamps may slip and fall off when they move towards each other to clamp them. Also, the forks are fixed in position and cannot be retracted into the clamps according to actual needs, which may hinder clamping. Therefore, a clamping fork is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping fork, comprising a main board, with clamping plates on both sides of one end of the main board, a driving structure for driving the two clamping plates to move in opposite directions, a telescopic rod on the opposite side of the two clamping plates, a connecting plate fixed to the opposite end of the two telescopic rods, a plurality of support blocks fixed to the opposite end of the two connecting plates, an arc-shaped clamping block fixed to the opposite end of every two support blocks, and a fork body slidably connected to the inner side of one end of each of the two clamping plates.

[0006] Preferably, the drive structure includes a first motor located on one side of the motherboard. The output end of the first motor passes through one side of the motherboard and is fixed with a bidirectional screw. Both ends of the outer wall of the bidirectional screw are threaded with moving blocks. Both ends of the two moving blocks are slidably connected with limit posts. One end of each of the two moving blocks is fixed with a connecting block. The ends of the two connecting blocks away from the moving blocks pass through the motherboard and are respectively fixed to two clamping plates.

[0007] Preferably, a second motor is installed inside the clamping plate, and a threaded rod is fixed to the output end of the second motor, the threaded rod being threadedly connected to the fork body.

[0008] Preferably, both ends of the fork body are fixed with limit blocks, and both ends of the inner wall of the clamping plate are provided with limit grooves that match the limit blocks.

[0009] Preferably, the end of the bidirectional screw away from the first motor is rotatably connected to the main board, and both ends of the limiting post are fixed to the main board.

[0010] Preferably, a first bracket is fixed to one end of the motherboard, the first motor is installed on the end of the first bracket facing the motherboard, and movable slots matching the connecting block are opened on both sides of one end of the motherboard.

[0011] Preferably, each of the two clamping plates has a second bracket fixed to one of its opposite ends, and each of the two telescopic rods has a second bracket fixed to one of its opposite ends.

[0012] Preferably, both ends of the motherboard are fixed with mounting plates, each mounting plate has mounting holes, and each clamping plate has a connecting groove that matches the arc-shaped clamping block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the two clamping plates can be moved in opposite directions to clamp and fix items with sharp edges. When it is necessary to clamp items with curved angles, it is only necessary to drive the two telescopic rods to run synchronously, causing the two connecting plates to move in opposite directions, thereby causing the two sets of support blocks and the two sets of curved clamping blocks to move in opposite directions. The two sets of curved clamping blocks pass through the two sets of connecting slots and are positioned between the two clamping plates. When the two clamping plates move in opposite directions, the two sets of curved clamping blocks will contact the items in advance, achieving the effect of firmly clamping items with curved angles, which is more practical. In addition, the device can drive the threaded rod to rotate through the operation of the second motor, so that the fork body can move under the limitation of the limiting block and the limiting slot. When the fork body is not used, it can be moved and retracted into the clamping plate. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1-4 As shown, this utility model provides a clamping fork, including a main board 1. Clamping plates 2 are provided on both sides of one end of the main board 1. The main board 1 is provided with a driving structure 3 for driving the two clamping plates 2 to move in opposite directions. Telescopic rods 9 are provided on the opposite sides of the two clamping plates 2. Connecting plates 10 are fixed to the opposite ends of the two telescopic rods 9. Multiple support blocks 11 are fixed to the opposite ends of the two connecting plates 10. Arc-shaped clamping blocks 12 are fixed to the opposite ends of every two support blocks 11. Fork bodies 13 are slidably connected to the inner sides of one end of the two clamping plates 2.

[0023] The overall effect of embodiment 1 is that, through the operation of the drive structure 3, the two clamping plates 2 can be driven to move towards each other, thereby clamping the items. Through the synchronous operation of the two telescopic rods 9, the two connecting plates 10 are driven to move towards each other, thereby driving the two sets of support blocks 11 and the two sets of arc-shaped clamping blocks 12 to move towards each other. The two sets of arc-shaped clamping blocks 12 will pass through the two clamping plates 2 respectively and be located between the two clamping plates 2. When the two clamping plates 2 move towards each other, the two sets of arc-shaped clamping blocks 12 will contact the items in advance, achieving the effect of firmly clamping the items with arc angles, which is more practical. Through the setting of the fork body 13, the items can be inserted and lifted for movement.

[0024] Example 2, as Figure 1-4As shown, the drive structure 3 includes a first motor 301 located on one side of the main board 1. The output end of the first motor 301 passes through one side of the main board 1 and is fixed with a bidirectional screw 302. Both ends of the outer wall of the bidirectional screw 302 are threadedly connected to moving blocks 303. Both ends of the two moving blocks 303 are slidably connected to limit posts 304. One end of each of the two moving blocks 303 is fixed with a connecting block 305. The ends of the two connecting blocks 305 away from the moving blocks 303 pass through the main board 1 and are respectively fixed to two clamping plates 2. A second motor 14 is installed inside the clamping plate 2. The output end of the second motor 14 is fixed with a threaded rod 15, which is threadedly connected to the fork body 13. Both ends of the fork body 13 are fixed with limit blocks 16. Both ends of the inner wall are provided with limiting grooves 17 that match the limiting block 16. The end of the bidirectional screw 302 away from the first motor 301 is rotatably connected to the main board 1. Both ends of the limiting post 304 are fixed to the main board 1. One end of the main board 1 is fixed with a first bracket 5. The first motor 301 is installed on the end of the first bracket 5 facing the main board 1. Both sides of one end of the main board 1 are provided with moving grooves 4 that match the connecting block 305. The opposite ends of the two clamping plates 2 are fixed with second brackets 8. The opposite ends of the two telescopic rods 9 are fixed with the two second brackets 8. Both ends of the main board 1 are fixed with mounting plates 6. Both mounting plates 6 are provided with mounting holes 7. Both clamping plates 2 are provided with connecting grooves 18 that match the arc-shaped clamping block 12.

[0025] The overall effect of Embodiment 2 is that the operation of the second motor 14 drives the threaded rod 15 to rotate, causing the fork body 13 to move under the limitation of the limiting block 16 and the limiting groove 17. When the fork body 13 is not needed, it can be moved and stored in the clamping plate 2. The operation of the first motor 301 drives the bidirectional screw 302 to rotate, causing the two moving blocks 303 to move towards each other under the limitation of the limiting post 304, thereby driving the two clamping plates 2 connected by the two connecting blocks 305 to move towards each other for clamping. The mounting plate 6 and the mounting hole 7 enable the main board 1 to be installed on the vehicle as a whole.

[0026] Working Principle: When in use, the device, through the mounting plate 6 and mounting holes 7, allows the main board 1 to be installed on the vehicle. The operation of the first motor 301 drives the bidirectional screw 302 to rotate, causing the two moving blocks 303 to move towards or away from each other under the limitation of the limiting post 304. This, in turn, causes the two clamping plates 2 connected by the two connecting blocks 305 to move towards or away from each other. The relative movement of the two clamping plates 2 allows for the clamping and fixing of objects with sharp edges. When clamping objects with rounded corners, simply drive the two telescopic rods 9 synchronously, causing the two connecting plates 10 to move towards each other. The two sets of support blocks 11 and two sets of arc-shaped clamping blocks 12 move towards each other, so that the two sets of arc-shaped clamping blocks 12 pass through the two sets of connecting slots 18 respectively and are located between the two clamping plates 2. When the two clamping plates 2 move towards each other, the two sets of arc-shaped clamping blocks 12 will contact the object in advance, so as to achieve the effect of firmly clamping the object with an arc angle. Through the operation of the second motor 14, the threaded rod 15 can be driven to rotate, so that the fork body 13 moves under the limit of the limit block 16 and the limit slot 17. When the fork body 13 is not needed, it can be moved and stored in the clamping plate 2.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
