Description

Technical Field

[0001] This utility model relates to the field of telescopic fork technology, specifically a wear-resistant and corrosion-resistant telescopic fork. Background Technology

[0002] With the rapid development of the logistics industry, automated storage and retrieval systems (AS / RS) are widely used across various sectors. Traditional fixed-length forks cannot meet the needs of goods of different sizes and different rack spacing. Telescopic forks can extend and retract horizontally, accommodating goods of different sizes and shapes, thus improving warehouse space utilization and cargo handling efficiency.

[0003] Most telescopic forks currently in use are not designed for easy extension and retraction, and lack surface protection. During use, traditional forks rub against their inner walls on both sides, increasing wear and tear and hindering smooth extension and retraction. This prevents the forks from maintaining good linear motion accuracy during extension and retraction, and also makes them unable to withstand certain lateral forces, resulting in poor extension and retraction performance. Without surface protection, the forks will rub against and collide with goods or the inner wall of the first fork during frequent picking up and extending, causing wear and deformation. Premature fork failure, coupled with the tendency for forks to corrode when handling corrosive goods, weakens their structural strength and shortens their lifespan. This results in poor wear and corrosion resistance, a shorter service life, and difficulty in securing the forks to a specific location. The inconvenience of securing the forks during use makes the installation process cumbersome, potentially leading to insecure installation and causing the forks to loosen or detach when handling heavy loads, resulting in damage. In short, the overall stability of the telescopic fork installation is poor. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant and corrosion-resistant telescopic fork to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and corrosion-resistant telescopic fork, comprising a support plate and a first fork, wherein a telescopic protective mechanism is provided on one side of the first fork, the telescopic protective mechanism comprising a fixing plate, the fixing plate being fixedly connected to one side of the first fork, a motor bracket being fixedly connected to one side of the support plate, a motor being fixedly connected to the inner side of the motor bracket, the output shaft of the motor being fixedly connected to a motor shaft via a coupling, the outer wall of the motor shaft being through-connected to one side of the support plate, and one end of the motor shaft being fixedly connected to... The ball screw has a ball nut movable on its outer wall. A slot is opened on one side of the first fork. A connecting rod is fixedly connected to the outer wall of the ball nut. A second fork is fixedly connected to one side of the connecting rod. A slide rail is fixedly connected inside the first fork. A slider is slidably connected to the outer wall of the slide rail. The outer wall of the slide rail is slidably connected to the inner wall of the connecting rod. A baffle is fixedly connected to one end of the slide rail. One end of the ball screw is rotatably connected to one side of the fixed plate. A chrome plating layer is fixedly connected to the top of both the first and second forks.

[0006] As a preferred technical solution, the number of motor brackets is two sets, with two brackets in each set, and the two motor brackets are symmetrically arranged with the vertical center line of the motor as the axis of symmetry.

[0007] As a preferred technical solution, the connecting rod has a through hole inside, the shape and size of which match the shape and size of the slide rail, and the connecting rod is slidably connected to the slide rail through the through hole.

[0008] As a preferred technical solution, the baffle is rectangular in shape, and there are two sets of baffles, with two baffles in each set.

[0009] As a preferred technical solution, the shape and size of the chrome plating layer match the shape and size of the second fork, and the shape and size of the chrome plating layer match the shape and size of the first fork.

[0010] As a preferred technical solution, a first fork is fixedly connected to the other side of the support plate, and the number of the first forks is two.

[0012] As a preferred technical solution, the mounting plate has a threaded hole inside, and the inner wall of the threaded hole is threaded with a bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of a telescopic protective mechanism, facilitates the extension and retraction of the forks while providing protection. During use, the starting motor drives the second fork to move and extend within the first fork. During this process, the sliding of the slider and the connecting rod on the outer wall of the slide rail ensures stable guidance for the forks while maintaining good linear motion accuracy and withstanding a certain lateral force. The chrome plating provides wear resistance and corrosion resistance, preventing the friction between the left and right sides of the forks and their inner walls during extension and retraction, which would otherwise increase wear and tear, as is common with traditional fork extension and retraction. This also prevents the forks from extending and retracting smoothly, maintaining good linear motion accuracy during extension and retraction, and being unable to withstand certain lateral forces. Ensuring the extension and retraction effect of the telescopic fork also avoids the friction and collision between the forks and the goods or the inner wall of the first fork during frequent picking or extension, which could lead to wear, deformation, and premature fork failure. Furthermore, when picking up corrosive goods, the forks are easily corroded, weakening their structural strength and shortening their service life. Therefore, this design ensures the wear-resistant and corrosion-resistant performance and service life of the telescopic fork.

[0015] 2. This utility model, through the setting of the installation and fixing mechanism, can facilitate the installation and fixing of the telescopic fork in a specific position. During use, the telescopic fork is installed and fixed in a specific position by the cooperation of bolts and threaded holes. This avoids the cumbersome installation process caused by the inconvenience of installing and fixing the telescopic fork in a specific position, which may lead to workers not installing the fork securely. As a result, the fork may loosen or fall off when lifting heavy goods, causing the goods to fall and break. This ensures the installation firmness of the telescopic fork. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 As shown, the present invention provides the following technical solution, including a support plate 1 and a first fork 4. A telescopic protective mechanism 2 is provided on one side of the first fork 4, and the first fork 4 is fixedly connected to the other side of the support plate 1. There are two first forks 4, and an installation and fixing mechanism 3 is provided at one end of the support plate 1.

[0025] Specifically: When the telescopic fork is needed, it must first be installed and fixed in a specific position using the installation and fixing mechanism 3. Once fixed, the first fork 4 can be used to pick up the goods. When the goods are large, the fork needs to be extended using the telescopic protection mechanism 2. After extension and retraction, the larger goods can be picked up. During the picking process, the telescopic protection mechanism 2 ensures that the telescopic fork is not affected by friction from the goods, friction during extension and retraction, or corrosiveness of the goods, thus completing the work.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a telescopic protective mechanism 2 is provided on one side of the first fork 4. The telescopic protective mechanism 2 includes a fixed plate 201. The fixed plate 201 is fixedly connected to one side of the first fork 4. A motor bracket 202 is fixedly connected to one side of the support plate 1. A motor 203 is fixedly connected to the inner side of the motor bracket 202. The output shaft of the motor 203 is fixedly connected to a motor shaft 204 through a coupling. The outer wall of the motor shaft 204 is connected through one side of the support plate 1. A ball screw 205 is fixedly connected to one end of the motor shaft 204. A ball nut 206 is movably attached to the outer wall of the ball screw 205. A slot 213 is opened on one side of the first fork 4. A connecting rod 207 is fixedly connected to the outer wall of the ball nut 206. A second fork 208 is fixedly connected to one side of the connecting rod 207. A slide rail 209 is fixedly connected inside the first fork 4. A slider 210 is slidably connected to the outer wall of the slide rail 209. The outer wall of the slide rail 209 is slidably connected to the inner wall of the connecting rod 207. One end of the slide rail 209 is fixedly connected to a baffle 211. One end of the ball screw 205 is rotatably connected to one side of the fixed plate 201. The top of the first fork 4 and the top of the second fork 208 are both fixedly connected to a chrome-plated layer 212. There are two sets of motor brackets 202, two in each set, and the two motor brackets 202 are symmetrically arranged with the vertical center line of the motor 203 as the axis of symmetry. The connecting rod 207 has a through hole inside, and the shape and size of the through hole match the shape and size of the slide rail 209. The connecting rod 207 is slidably connected to the slide rail 209 through the through hole. The baffle 211 is rectangular in shape, and there are two sets of baffles 211, two in each set. The shape and size of the chrome-plated layer 212 match the shape and size of the second fork 208, and the shape and size of the chrome-plated layer 212 match the shape and size of the first fork 4.

[0027] Specifically: When the goods are large, the forks need to be extended. At this time, motor 203 is started, causing motor shaft 204 to rotate. Motor shaft 204 drives ball screw 205 to rotate, which in turn drives ball nut 206 to move along its outer wall. Ball nut 206 then drives connecting rod 207 to move within slot 213. Connecting rod 207 then drives the second fork 208 to move. During the movement of the second fork 208, the sliding of connecting rod 207 and slider 210 along the outer wall of slide rail 209 causes the second fork 208 to move. The movement is smoother and more stable, and the left and right sides of the second fork 208 do not rub against the inner wall of the first fork 4. The chrome plating layer 212 also prevents the top of the second fork 208 from rubbing against the inner wall of the first fork 4, so that the second fork 208 can be extended to the appropriate position to complete the extension and retraction. After extension and retraction, larger goods can be picked up. During the picking process, the chrome plating layer 212 can give the first fork 4 and the second fork 208 certain wear and corrosion resistance, preventing the surface of the goods from being corroded, and also preventing the first fork 4 and the second fork 208 from rubbing against each other when picking up goods, thus completing the protection work.

[0028] like Figure 1 , Figure 5 and Figure 6 As shown, a mounting and fixing mechanism 3 is provided at one end of the support plate 1. The mounting and fixing mechanism 3 includes a mounting plate 301. The mounting plate 301 is fixedly connected to one end of the support plate 1. A threaded hole 302 is opened inside the mounting plate 301. A bolt 303 is threadedly connected to the inner wall of the threaded hole 302.

[0029] Specifically: When the telescopic fork is needed, it is first necessary to install and fix the telescopic fork in a specific position. At this time, the mounting plates 301 on both sides of the support plate 1 are aligned with the specific position. Then, the threaded holes 302 in the mounting plate 301 are aligned with the threaded holes 302 in the specific position. Then, the bolts 303 are rotated and inserted into the threaded holes 302 to fix the mounting plate 301 in the specific position, thereby completing the installation and fixing work.

[0030] The working principle of this utility model is as follows: When the telescopic fork is needed, it is first necessary to install and fix the telescopic fork in a specific position. At this time, the mounting plates 301 on both sides of the support plate 1 are aligned with the specific position. Then, the threaded holes 302 in the mounting plate 301 are aligned with the threaded holes 302 in the specific position. Then, the bolts 303 are rotated and inserted into the threaded holes 302 to fix the mounting plate 301 in the specific position, thus completing the installation and fixing work. After fixing, the first fork 4 can be used to pick up goods. When the goods are large, the fork needs to be extended. At this time, the motor 203 is started, which drives the motor shaft 204 to start rotating. The motor shaft 204 drives the ball screw 205 to start rotating. The ball screw 205 drives the ball nut 206 to move on the outer wall of the ball screw 205. The ball nut 206 drives the connecting rod 207 to start moving, so that the connecting rod 207 is in the slot. 213 moves inward, and the connecting rod 207 drives the second fork 208 to move. During the movement of the second fork 208, the sliding of the connecting rod 207 on the outer wall of the slide rail 209 and the sliding of the slider 210 on the outer wall of the slide rail 209 make the movement of the second fork 208 more stable and smooth. At the same time, it prevents the left and right sides of the second fork 208 from rubbing against the inner wall of the first fork 4. The chrome plating layer 212 also prevents the top of the second fork 208 from rubbing against the inner wall of the first fork 4, so that the second fork 208 can be extended to a suitable position, thus completing the extension and retraction work. After extension and retraction, larger goods can be picked up. During the picking process, the chrome plating layer 212 can make the first fork 4 and the second fork 208 have certain wear resistance and corrosion resistance, preventing the surface of the goods from being corroded, and also preventing the first fork 4 and the second fork 208 from rubbing against each other when picking up goods, thus completing the protection work.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
