Description

Technical Field

[0001] This utility model relates to the field of forklift loading platforms, and in particular to a guardrail anti-sway structure for forklift loading platforms. Background Technology

[0002] A forklift loading platform is a hydraulic, pneumatic, or mechanical device used for loading and unloading. It is also called a loading and unloading platform, unloading dock, or cargo platform, and is a type of logistics equipment. It is divided into two types: fixed loading and unloading platforms and mobile loading and unloading platforms. Forklift loading platforms are used for loading and unloading operations. The sides of the forklift loading platform are bolted guardrails to ensure the safety of the forklift during the transportation of goods. Over time and during the use of the loading platform, the bolts may loosen, causing the guardrails to sway. Therefore, the guardrails need to be reinforced.

[0003] In related technologies, bolts are used to fix fences. After long-term exposure to the outdoor environment, metal bolts are easily corroded by rainwater, air oxidation and chemical corrosion, resulting in a rust layer on the surface, which leads to a decrease in thread engagement. In addition, the bolt preload will gradually decrease, forming structural gaps, causing the fence to loosen and affecting the safety of the work.

[0004] Therefore, it is necessary to provide a guardrail anti-sway structure for forklift loading platforms to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a guardrail anti-sway structure for forklift loading platforms.

[0006] This utility model provides a guardrail anti-sway structure for forklift loading platforms, including...

[0007] The platform and the mounting slots on both sides of the platform;

[0008] The transmission assembly includes two first transmission rods, one end of which is rotatably connected to the side wall of the fixed groove, and the other end of which is fixedly connected to a universal joint. The right end of the universal joint is fixedly connected to a second transmission rod, and the right side of the second transmission rod extends through to the right side of the platform. Protective frames are fixedly connected to the surfaces of both the first and second transmission rods.

[0009] A locking assembly comprising two ratchet wheels fixedly connected to the surface of a first transmission rod, wherein a pawl engages on the top of each ratchet wheel.

[0010] Preferably, the transmission assembly includes a gear, which is fixedly connected to the end of the second transmission rod away from the first transmission rod. The surface of the gear is meshed with a toothed plate. A threaded sleeve is slidably connected to the side wall of the platform. The toothed plate is fixedly connected to the threaded sleeve. A motor is fixedly installed on the side wall of the platform. A screw is fixedly connected to the output end of the motor. The screw is threadedly connected to the threaded sleeve.

[0011] Preferably, the locking assembly includes two fixing brackets, which are fixedly connected to the side wall of the platform. The pawl is rotatably connected to the fixing brackets. A mounting plate is fixedly connected to the outer side of the fixing brackets. An electric push rod is fixedly connected to the side wall of the mounting plate. A steel cable is fixedly connected to the telescopic end of the electric push rod. The inner side of the steel cable is fixedly connected to the surface of the pawl. A spring is fixedly connected to the side wall of the pawl. The end of the spring away from the pawl is fixedly connected to the surface of the mounting plate.

[0012] Preferably, four positioning slide rods are fixedly connected to the surface of the platform, and the four positioning slide rods are slidably connected to the threaded sleeves.

[0013] Preferably, at least three positioning rings are fixedly connected to the side wall of the fixing groove, and both the first transmission rod and the second transmission rod are rotatably connected to at least three of the positioning rings.

[0014] Preferably, the locking component further includes two triangular blocks, both of which are fixedly connected to the two fixing frames and both of which are fixedly connected to the platform.

[0015] Compared with related technologies, the anti-sway structure for guardrails of forklift loading platforms provided by this utility model has the following beneficial effects:

[0016] 1. During forklift operation, the protective frame can be used to protect both sides of the platform to ensure forklift safety. When transporting oversized goods, the motor can be started. The motor's output rotates, driving the screw to rotate. The screw rotation drives the threaded sleeve to move upwards, and the threaded sleeve simultaneously drives the toothed plate to move. The movement of the toothed plate drives the gear to rotate. The gear rotates outwards, simultaneously causing the second transmission rod, universal joint, and first transmission rod to flip, making the fixed frame rotate at a certain angle to facilitate goods transportation. By using high-strength steel for the second transmission rod, universal joint, and first transmission rod, the stability of the fixed frame can be guaranteed, preventing wobbling. This solves the problem that after long-term exposure to outdoor environments, metal bolts are easily corroded by rainwater, air oxidation, and chemical corrosion, resulting in a rust layer on the surface, which leads to a decrease in thread engagement, a gradual decrease in bolt preload, the formation of structural gaps, and the loosening of the guardrail, affecting work safety.

[0017] 2. As the first transmission rod rotates, the ratchet is driven to rotate as well. When the first transmission rod stops, it can be fixed to prevent it from rotating back. When the first transmission rod needs to be reset, the user activates the two parallel electric push rods to retract, tighten the steel cable, and disengage the pawl from the ratchet, allowing the first transmission rod to reset. This ensures the safety of the first transmission rod, prevents it from rotating back after reset, and provides excellent locking and stability. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1 to 6 A guardrail anti-sway structure for a forklift loading platform 1, comprising:

[0027] Platform 1 and fixing slots 2 opened on both sides of platform 1;

[0028] The transmission assembly 3 includes two first transmission rods 36. One end of each first transmission rod 36 is rotatably connected to the side wall of the fixed groove 2. The other end of each first transmission rod 36 is fixedly connected to a universal joint 37. The right end of the universal joint 37 is fixedly connected to a second transmission rod 38. The right side of the second transmission rod 38 extends through to the right side of the platform 1. Protective frames 39 are fixedly connected to the surfaces of both the first transmission rod 36 and the second transmission rod 38.

[0029] Locking assembly 4 includes two ratchet wheels 47, which are fixedly connected to the surface of the first transmission rod 36, and a pawl 48 is engaged on the top of the ratchet wheels 47.

[0030] The transmission assembly 3 includes a gear 31, which is fixedly connected to the end of the second transmission rod 38 away from the first transmission rod 36. A toothed plate 32 meshes with the surface of the gear 31. A threaded sleeve 33 is slidably connected to the side wall of the platform 1. The toothed plate 32 is fixedly connected to the threaded sleeve 33. A motor 34 is fixedly installed on the side wall of the platform 1. A screw 35 is fixedly connected to the output end of the motor 34. The screw 35 is threadedly connected to the threaded sleeve 33.

[0031] The locking assembly 4 includes two fixing brackets 41, which are fixedly connected to the side wall of the platform 1. The pawl 48 is rotatably connected to the fixing brackets 41. A mounting plate 42 is fixedly connected to the outer side of the fixing brackets 41. An electric push rod 43 is fixedly connected to the side wall of the mounting plate 42. A steel cable 44 is fixedly connected to the telescopic end of the electric push rod 43. The inner side of the steel cable 44 is fixedly connected to the surface of the pawl 48. A spring 45 is fixedly connected to the side wall of the pawl 48. The end of the spring 45 away from the pawl 48 is fixedly connected to the surface of the mounting plate 42.

[0032] In practical implementation, when encountering oversized cargo transportation, motor 34 can be started. The output end of motor 34 rotates, driving screw 35 to rotate. The rotation of screw 35 drives screw sleeve 33 to move upward. Screw sleeve 33 simultaneously drives toothed plate 32 to move. The movement of toothed plate 32 drives gear 31 to rotate. Gear 31 rotates outward, simultaneously driving the second transmission rod 38, universal joint 37, and first transmission rod 36 to flip, causing the protective frame 39 to flip at a certain angle, facilitating cargo transportation. By using high-strength steel for the second transmission rod 38, universal joint 37, and first transmission rod 36, the stability of the protective frame 39 can be guaranteed, preventing swaying. Through the setting of transmission component 3, the second transmission rod 38, universal joint 37, and first transmission rod 36 can be used to ensure the stability of the protective frame 39 and prevent swaying. The two transmission rods 38 effectively transmit power, enabling them to rotate stably and precisely with high transmission efficiency. The locking component 4 prevents the first transmission rod 36 from rotating back, effectively ensuring its safety. During the rotation of the first transmission rod 36, the ratchet 47 is driven to rotate. When the first transmission rod 36 stops, the pawl 48 can clamp and fix the ratchet 47 to prevent rotation, thus avoiding the problem of the first transmission rod 36 rotating back. When the first transmission rod 36 needs to be reset, the user activates the two parallel electric push rods 43, causing them to retract and tighten the steel cable 44, disengaging the pawl 48 from the ratchet 47, allowing the first transmission rod 36 to reset.

[0033] It should be noted that: the first transmission rod 36 and the second transmission rod 38 are both solid 50 high-quality carbon steel, the universal joint 37 is made of 50 high-quality carbon steel, the universal joint 37 is specifically a three-pin universal joint 37, the motor 34 is a stepper motor 34, and the two electric push rods 43 are set in parallel to achieve the effect of synchronous start and stop.

[0034] refer to Figure 5 As shown, four positioning slide rods 5 are fixedly connected to the surface of platform 1, and the four positioning slide rods 5 are slidably connected to the screw sleeve 33.

[0035] Furthermore, by setting the positioning slide bar 5, the position of the screw sleeve 33 can be limited to ensure the stability of the screw sleeve 33 and prevent the screw sleeve 33 from shaking.

[0036] refer to Figure 1 As shown, at least three positioning rings 6 are fixedly connected to the side wall of the fixed groove 2, and the first transmission rod 36 and the second transmission rod 38 are rotatably connected to the at least three positioning rings 6.

[0037] Furthermore, the positioning ring 6 provides support and protection for the first transmission rod 36 and the second transmission rod 38, ensuring their safety and preventing them from wobbling.

[0038] refer to Figure 6 As shown, the locking component 4 also includes two triangular blocks 46, both of which are fixedly connected to two fixing brackets 41 and both of which are fixedly connected to the platform 1.

[0039] Furthermore, the triangular block 46 is used to support the fixing frame 41, which can ensure the stable operation of the locking component 4 and effectively extend the service life and support performance of the fixing frame 41.

[0040] The working principle of the anti-sway structure for the guardrail of a forklift loading platform 1 provided by this utility model is as follows:

[0041] During forklift operation, the protective frame 39 protects both sides of the platform 1 to ensure forklift safety. When transporting oversized goods, the motor 34 can be started. The output of the motor 34 rotates, driving the screw 35 to rotate. The screw 35's rotation causes the screw sleeve 33 to move upwards, simultaneously moving the toothed plate 32. The toothed plate 32's movement drives the gear 31 to rotate. The gear 31's outward rotation simultaneously causes the second transmission rod 38, universal joint 37, and first transmission rod 36 to flip, causing the protective frame 39 to flip at a certain angle, facilitating goods transport. High-strength steel is used in this design. The second drive rod 38, universal joint 37, and first drive rod 36 of the material can ensure the stability of the protective frame 39 and prevent wobbling. Secondly, when the first drive rod 36 rotates, the ratchet 47 is driven to rotate. When the first drive rod 36 stops, it can be fixed to prevent the first drive rod 36 from rotating back. When the first drive rod 36 needs to be reset, the user activates the two parallel electric push rods 43 to retract the electric push rods 43, tighten the steel cable 44, and disengage the pawl 48 from the ratchet 47, so that the first drive rod 36 can be reset, thereby ensuring the safety of the first drive rod 36.
