Description

Technical Field

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

[0002] During the production process in the workshop, a large number of products need to be boxed and packaged after production, and then transferred to the warehouse for stacking. In order to improve the transfer efficiency of boxed products, forklifts often use their forks to lift some of the stacked boxes and transfer them to the warehouse. As the forks rise and fall and move, the boxes are stacked to the designated position.

[0003] Common clamp-type conveyor forks are installed at the front of a forklift. A motor drives the forks on both sides to clamp and lift the cargo box. The forklift then transports the cargo box to the warehouse, and the motor again places the cargo box in the designated location within the warehouse. Common clamp-type conveyor forks offer good cargo handling efficiency, but some problems still exist:

[0004] When using common clamp-type conveyor forks, due to the large number of goods placed and stacked in the warehouse, if the boxes to be retrieved are stacked at the bottom, the forks can only transfer the boxes at the top to other locations before retrieving them. Then, the boxes at the top that have been transferred need to be re-stacked, which makes the functionality of common clamp-type conveyor forks somewhat lacking. Utility Model Content

[0005] The purpose of this invention is to provide a clamping conveyor fork to solve the problem that existing clamping conveyor forks have limited single clamping function during use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clamping conveyor fork, including a mounting base and a second lifting frame. An outer drive frame is fixedly connected to the top of the mounting base, and an inner drive frame is fixedly connected to the inner side of the outer drive frame. A first lifting frame is slidably connected to one end of the inner drive frame, and a second lifting frame is slidably connected to one end of the outer drive frame. A ball screw is rotatably connected to the inner and outer drive frames. A clamping mechanism is slidably connected to one end of the second lifting frame. The clamping mechanism includes an outer frame, a clamping plate, a push plate, an adjusting screw, a motor assembly, a first bevel gear, and a second bevel gear. The outer frame is slidably connected to one end of the first and second lifting frames. A screw seat is threaded to the outer side of the ball screw. A belt assembly is provided above the outer wall of the ball screw, and a lubrication structure is installed at the top of the screw seat.

[0007] In use, the first and second lifting frames are raised and lowered as needed by the motor and belt assembly at the top of the outer and inner driving frames. At the same time, since the second lifting frame is equipped with a bidirectional screw threaded to the outer frame, the two clamping mechanisms can clamp the goods under the drive of the motor.

[0008] Preferably, a clamping plate is slidably connected to the inside of one side of the outer frame, one end of the clamping plate extends through to the other side of the outer frame and is fixedly connected to one side of the push plate, an adjusting screw extends through the inside of the push plate, a motor assembly is fixedly connected to one end of the other side of the outer frame, a first bevel gear is fixedly connected to the top of the motor assembly, and a second bevel gear is fixedly connected to one end of the outer wall of the adjusting screw. The extension and retraction of the clamping plate allows the clamping conveyor fork to clamp the cargo box at a greater distance.

[0009] Preferably, the push plate and the adjusting screw are connected by a thread, and the two ends of the second bevel gear are rotated with one side of the outer frame, so as to make the rotation of the adjusting screw more stable.

[0010] Preferably, the first bevel gear and the second bevel gear are meshed, thereby allowing the adjusting screw to rotate.

[0011] Preferably, the lubrication structure includes a reservoir, an inner tube, a sponge ring, an oil-absorbing sponge, an oil inlet, and a top plug. The reservoir is installed at the top of the ball screw seat. An inner tube is fixedly connected inside the reservoir. A sponge ring is fixedly connected to the inner side of the inner tube. An oil-absorbing sponge is fixedly connected to the outer side of the sponge ring. An oil inlet is provided on one side of the top of the reservoir. A top plug is installed inside the oil inlet. With the application of the oil-absorbing sponge, a large amount of lubricating oil is applied to the outer side of the ball screw.

[0012] Preferably, the cross-sectional area of ​​the inner diameter of the oil-absorbing sponge is the same as the cross-sectional area of ​​the outer diameter of the ball screw, and the sponge rings are evenly distributed on the inner wall of the inner tube, so that the sponge rings avoid friction and damage to the inner wall while applying lubricating oil.

[0013] Preferably, several oil-absorbing sponges are fixedly connected to the outer wall of the sponge ring, and the several oil-absorbing sponges are arranged in a ring on the outer wall of the sponge ring, so as to make the lubricant application more even.

[0014] Compared with the prior art, the beneficial effects of this utility model are: through the extension and retraction of the double clamping mechanism and clamping plate, the fork can more easily remove the goods in the required position, and after the fork is used frequently, the sponge ring absorbs and removes the lubricating oil to the outer wall of the ball screw, thereby reducing wear.

[0015] 1. By controlling the forward and reverse rotation of the adjusting screw, the push plate can push the clamping plate to extend outward, thereby enabling the clamping conveyor forks to clamp and remove the cargo box from a distance.

[0016] Furthermore, when the required goods are below the stacked boxes, the front clamping mechanism of the second lifting frame can clamp and lift the stacked boxes above the required boxes, and then drive the front clamping mechanism of the first lifting frame to remove the required boxes, thereby making the use of the clamping conveyor fork more convenient.

[0017] 2. A large amount of lubricating oil is injected into the reservoir through the oil inlet, allowing the lubricating oil to spread to the sponge ring. As the screw seat moves up and down along the outer side of the ball screw, the sponge ring, which absorbs a large amount of lubricating oil, will gradually coat the outer wall of the ball screw with lubricating oil.

[0025] Please see Figures 1-5 This utility model provides a clamping conveyor fork, including a mounting base 1 and a second lifting frame 5. An outer drive frame 2 is fixedly connected to the top of the mounting base 1, and an inner drive frame 3 is fixedly connected to the inner side of the outer drive frame 2. A first lifting frame 4 is slidably connected to one end of the inner drive frame 3, and a second lifting frame 5 is slidably connected to one end of the outer drive frame 2. A ball screw 7 is rotatably connected to the inner drive frame 3 and the outer drive frame 2. A screw seat 8 is threadedly connected to the outer side of the ball screw 7. A belt assembly 9 is disposed above the outer wall of the ball screw 7. A clamping mechanism 6 is slidably connected to one end of the second lifting frame 5. The clamping mechanism 6 includes an outer frame 601, a clamping plate 602, a push plate 603, an adjusting screw 604, a motor assembly 605, a first bevel gear 606, and a second bevel gear 607. 7. The outer frame 601 is slidably connected to one end of the first lifting frame 4 and the second lifting frame 5. A clamping plate 602 is slidably connected inside one side of the outer frame 601. One end of the clamping plate 602 extends through to the other side of the outer frame 601 and is fixedly connected to one side of the push plate 603. An adjusting screw 604 extends through the inside of the push plate 603. A motor assembly 605 is fixedly connected to one end of the other side of the outer frame 601. A first bevel gear 606 is fixedly connected to the top of the motor assembly 605. A second bevel gear 607 is fixedly connected to one end of the outer wall of the adjusting screw 604. The push plate 603 and the adjusting screw 604 are threadedly connected. The two ends of the second bevel gear 607 are rotating with one side of the outer frame 601. The first bevel gear 606 and the second bevel gear 607 are meshing.

[0026] See attached document Figure 1 and Figure 3When the clamping conveyor fork is in use, if the goods are placed at a distance, the drive motor assembly 605 causes the first bevel gear 606 to drive the second bevel gear 607 and the adjusting screw 604 to rotate. By controlling the forward and reverse rotation of the adjusting screw 604, the push plate 603 can push the clamping plate 602 to extend outward, thereby allowing the clamping conveyor fork to clamp and remove the goods from a distance. Since the clamping conveyor fork is equipped with a first lifting frame 4 and a second lifting frame 5, and the first lifting frame 4... Both the front end of the second lifting frame 5 and the front end of the first lifting frame 4 are equipped with a clamping mechanism 6. When the required goods are below the stacked boxes, the ball screw 7 at the outer drive frame 2 can be driven to clamp the box stacked on top of the required box at the front end of the second lifting frame 5. Then, the ball screw 7 at the inner drive frame 3 can be driven to remove the required box from the front end of the first lifting frame 4. Then, the box clamped by the front end of the second lifting frame 4 is placed back in its original position, thus making the use of the clamping conveyor fork more convenient.

[0027] A lubrication structure 10 is installed at the top of the lead screw seat 8. The lubrication structure 10 includes a reservoir 1001, an inner tube 1002, a sponge ring 1003, an oil-absorbing sponge 1004, an oil inlet 1005, and a top plug 1006. The reservoir 1001 is installed at the top of the lead screw seat 8. The inner tube 1002 is fixedly connected inside the reservoir 1001. The sponge ring 1003 is fixedly connected to the inner side of the inner tube 1002. The oil-absorbing sponge 1004 is fixedly connected to the outer wall of the sponge ring 1003. An oil inlet 1005 is provided on one side of the top of the liquid storage tank 1001. A top plug 1006 is installed inside the oil inlet 1005. The cross-sectional area of ​​the inner diameter of the oil-absorbing sponge 1004 is the same as the cross-sectional area of ​​the outer diameter of the ball screw 7. The sponge rings 1003 are evenly distributed on the inner wall of the inner tube 1002. Several oil-absorbing sponges 1004 are fixedly connected to the outer wall of the sponge rings 1003, and the several oil-absorbing sponges 1004 are distributed in a ring on the outer wall of the sponge rings 1003.

[0028] See attached document Figure 2 , Figure 4 and Figure 5Because the clamping conveyor fork drives the first lifting frame 4 and the second lifting frame 5 up and down through the threaded connection between the ball screw 7 and the screw seat 8, thereby lifting and lowering the goods, the frequent use of the ball screw 7 and the screw seat 8, coupled with the weight of the goods, makes the ball screw 7 and the screw seat 8 prone to wear, thus affecting the service life of the clamping conveyor fork. To address this, a liquid storage tank 1001 is installed above the screw seat 8, and a large amount of lubricating oil is injected into the liquid storage tank 1001 through the oil inlet 1005. Since the oil-absorbing sponge 1004 can absorb the lubricating oil and spread it to the sponge ring 1003, as the screw seat 8 moves up and down along the outside of the ball screw 7, the sponge ring 1003, which absorbs a large amount of lubricating oil, will gradually coat the outer wall of the ball screw 7 with lubricating oil, thereby reducing its wear.
