[0001] This utility model relates to an explosion-proof forklift, and more particularly to a securely mounted explosion-proof forklift, belonging to the technical field of explosion-proof forklifts. Background Technology

[0002] Explosion-proof forklifts are special industrial vehicles designed for use in environments with explosive hazards, such as chemical, petroleum, pharmaceutical, food processing, military, and gas industries. Through special technical modifications and safety designs, their bodies can effectively avoid the generation of sparks, high temperatures, static electricity, and other dangerous factors that may cause explosions during operation, thereby ensuring safe operation in flammable and explosive locations.

[0003] Explosion-proof forklifts mainly consist of a power system, electrical system, safety protection system, control system, and body and mechanical structure. Among them, the forks and fork carriages in the mechanical structure are important tools for forklifts to transfer goods. During the process of picking up and turning goods, multiple or stacked goods often appear on the forks according to transportation needs. When the body turns or moves, the stacked goods will sway from side to side due to the influence of vehicle speed and road conditions. Since there is no structural device on the fork carriage to stabilize the goods, the goods are prone to tipping over.

[0004] Therefore, there is an urgent need to improve the securely mounted explosion-proof forklifts to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a securely mounted explosion-proof forklift. By setting auxiliary plates on both sides of the forks, when transporting stacked goods on the forks, the two auxiliary plates are driven by a drive unit to slide synchronously towards the goods on a sliding track. When the auxiliary plates come into contact with the goods, they can provide lateral auxiliary restraint for the goods, thereby making the goods more stable on the forks. When the explosion-proof forklift is transporting goods, it prevents the goods from swaying from side to side, ensuring that the goods are placed on the forks securely.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figures 1-7 As shown, the explosion-proof forklift provided in this embodiment includes a main body 1, which refers to the explosion-proof forklift body 1, a fork carriage 2 and forks 3 provided on the main body 1, a lifting mechanism 4 provided on the fork carriage 2, an ascending frame 5 and forks 3 connected to the ascending frame 5 on the lifting mechanism 4. The lifting mechanism 4 is an existing structure on the explosion-proof forklift body structure. Its main purpose is to vertically lift the ascending frame 5 and forks 3, thereby moving the goods away from the ground. Its power system can be an explosion-proof motor driving a chain or a hydraulic cylinder, both of which are existing technologies and will not be described in detail. The device also includes a sliding rail 6, an auxiliary plate 7 and a driving component 8.

[0027] Specifically, the aforementioned sliding rail 6 is connected to the lifting frame 5 and extends perpendicularly to the extension direction of the fork 3. The sliding rail 6 is provided with a sliding groove 601 extending through both ends. The auxiliary plates 7 slide symmetrically on the sliding groove 601 and are located on both sides of the fork 3. The driving component 8 is used to drive the two auxiliary plates 7 to move relative to each other in the sliding groove 601. When the fork 3 is carrying a stack of goods, the driving component 8 drives the two auxiliary plates 7 to slide synchronously towards the goods position on the sliding rail 6. When the auxiliary plates 7 come into contact with the goods, they can provide left and right auxiliary limiting for the goods, thereby making the goods more stable on the fork 3. When the main body 1 is carrying goods, it avoids the goods from swaying left and right, making the goods more secure when placed on the fork 3. Compared with the fork 3 carrying goods by itself, by setting this device, the fork 3 can carry higher goods and makes the goods more stable during the transfer process.

[0028] To achieve the above effect, specifically, such as Figures 3-5 As shown, a gear part 602 is provided in the middle of the sliding track 6, and a rotating base 603 is connected to the sliding groove 601 on both sides of the gear part 602 respectively; the auxiliary plate 7 includes a sliding plate 71 and a support plate 72; wherein, a telescopic groove 73 with both ends passing through is provided on the sliding plate 71, and a threaded block 9 is connected to one end of the telescopic groove 73 near the gear part 602.

[0029] The driving component 8 includes a bidirectional threaded rod 81 and a power component for driving the bidirectional threaded rod 81 to rotate. The middle portion of the bidirectional threaded rod 81 is rotatably connected to two rotating bases 603. Both ends of the bidirectional threaded rod 81 extend to the ends of the sliding grooves 601 via telescopic grooves 73 on two sliding plates 71, and are connected to the sliding rails 6 via rotating bases 82. The rotating bases 82 primarily provide a limit for the rotation of the bidirectional threaded rod 81, ensuring stable rotation at its ends. Both ends of the bidirectional threaded rod 81 are threadedly connected to threaded blocks 9 on the two sliding plates 71. In use, the power component rotates the rod. The bidirectional threaded rod 81 rotates stably within the sliding groove 601 under the action of the rotating base 603. Both the rotating base 603 and the aforementioned rotating base 82 can be bearing bases in the prior art. Their main purpose in this device is to stabilize the rotation of the bidirectional threaded rod 81, which will not be described in detail. While the bidirectional threaded rod 81 rotates, the threaded block 9 drives the sliding plate 71 to move within the sliding groove 601. The two sliding plates 71 move at the same speed but in opposite directions. When the sliding plate 71 moves, it can drive the support plate 72 to move, thereby providing auxiliary limiting and clamping stability for the goods on the forks 3.

[0030] Furthermore, the aforementioned power components include a driven gear 10, a driving gear 11, and a drive motor 12. The driven gear 10 is connected to the bidirectional threaded rod 81 and located at the gear section 602. A shaft bracket 13 is connected to the sliding rail 6. The driving gear 11 is connected to the shaft bracket 13 via a drive shaft 14. The drive motor 12 is mounted on one side of the shaft bracket 13, and the output end of the drive motor 12 is connected to the drive shaft 14. In actual use, by running the drive motor 12, the drive shaft 14 drives the driving gear 11 to rotate, which in turn drives the driven gear 10 that meshes with it to rotate. Finally, the driven gear 10 drives the bidirectional threaded rod 81 to rotate on the rotating base 603. The drive motor 12 can be controlled by the existing control system on the main body 1 or by manual switching, without limitation. This is prior art and will not be described in detail.

[0031] Furthermore, such as Figures 6-8As shown, the support plate 72 includes a fixed plate 15 and a rotating plate 16. The fixed plate 15 is connected to the sliding plate 71, and the extension direction of the fixed plate 15 is perpendicular to the extension direction of the sliding plate 71. A rotating part 150 is provided on the end of the fixed plate 15 away from the sliding plate 71. The rotating plate 16 is rotatably connected to the rotating part 150. The specific rotation direction can be connected according to the actual situation. A bearing can be used for rotational connection. The specific direction is not limited. The rotational connection direction is a common existing structure and technology, and will not be described in detail. The support plate 72 is provided with a locking component for locking the rotating plate 16. Rotating the rotating plate 16 so that it is perpendicular to the fixed plate 15 can increase the stability of the goods and make the goods less likely to sway left and right.

[0032] Furthermore, to prevent the rotating plate 16 in its vertical position from rotating and thus avoiding its impact from goods, the locking assembly includes a locking ring 17, a pin 18, a spring plate 19, a telescopic spring 20, and a sliding plate 21. The rotating part 150 has a through slot 151. The locking ring 17 is connected to the rotating plate 16 and located within the through slot 151. The locking ring 17 has several arc-shaped toothed grooves 170 equidistantly arranged around its central axis. The sliding plates 21 are all connected within the through slots 151. The spring plate 19 is connected to the pin 18, which slides on the sliding plate 21. One end of the pin 18 extends towards the locking ring 17 and has a pressing part 180. The pressing part 180 engages with the arc-shaped toothed grooves 170. The edges of the arc-shaped toothed grooves 170 are arc-shaped to facilitate the movement of the pressing part 180. When the locking ring 17 rotates, its arc-shaped toothed grooves 170 will... The pressing part 180 of the push pin 18 switches back and forth between two states: away from the arc-shaped tooth groove 170 and engaged in the arc-shaped tooth groove 170, as the locking ring 17 rotates. The telescopic spring 20 is located between the spring plate 19 and the sliding plate 21, and the two ends of the telescopic spring 20 are connected to the spring plate 19 and the sliding plate 21 respectively. When the arc-shaped tooth groove 170 pushes the pressing part 180 away from the arc-shaped tooth groove 170, the telescopic spring 20 is compressed by the action of the sliding plate 21. When the pressing part 180 moves to the next arc-shaped tooth groove 170, the telescopic spring 20 releases its elastic force, and the pressing part 180 will re-engage in the arc-shaped tooth groove 170. When the arc-shaped tooth groove 170 pushes the pressing part 180, the action of the telescopic spring 20 will increase the friction of the rotating plate 16 when it rotates on the rotating part 150, so that it will not easily rotate.

[0033] Next, as Figure 7 as well as Figure 8As shown, to further lock the rotating plate 16 and increase its anti-interference capability, a bolt 22 is connected to the end of the pin 18 away from the pressing part 180. A limit plate 24 is connected to the rotating part 150, and a through limit groove 25 is provided on the limit plate 24. The end of the bolt 22 away from the pin 18 is adapted to pass through the limit groove 25. A limit nut 23 is threaded onto the bolt 22, and the limit nut 23 is located between the limit groove 25 and the sliding plate 21. The limit nut 23 cannot pass through the limit groove 25. When the limit nut 23 is rotated and moves towards the limit groove 25 until it abuts against the limit plate 24, this... When the locking ring 17 is rotated, its arc-shaped toothed groove 170 cannot push the pin 18 to move, thus causing the pressing part 180 to be tightly locked in the arc-shaped toothed groove 170, thereby limiting the rotation plate 16. When the limiting nut 23 is rotated to move away from the limiting groove 25 until it is close to the sliding plate 21, the locking ring 17 is rotated, and its arc-shaped toothed groove 170 will push the pin 18 to move, thereby allowing the rotation plate 16 to rotate. The rotating plate 16 can be conveniently folded on the fixed plate 15 when not in use to avoid damage to the rotating plate 16. When in use, it should be placed perpendicular to the fixed plate 15.
