Description

Technical Field

[0001] This utility model relates to the field of road freight transport anti-fall technology, specifically to a road freight transport anti-fall mechanism. Background Technology

[0002] Beneficial Effects: In the field of road freight transport, the safety of goods during transportation has always been one of the core concerns of the industry. With the rapid development of the logistics industry, the volume of road freight transport is constantly increasing, and the types of transported goods are becoming increasingly complex, covering various materials of different weights and shapes.

[0003] In real-world transportation scenarios, freight vehicles face various challenges during operation, including complex road conditions, changes in speed, turns, and braking. These factors can all cause cargo inside the truck to shift, tip over, or even fall. Falling cargo not only damages the goods themselves, resulting in direct economic losses, but can also trigger traffic accidents, threatening the lives of drivers, other vehicle occupants, and pedestrians. Furthermore, it can disrupt traffic flow, causing congestion and other related problems.

[0004] However, existing cargo securing methods in freight vehicles mostly rely on traditional methods such as rope binding and barrier bars. These methods have significant limitations: firstly, the tightness of rope binding depends on the operator's experience, resulting in inconsistent securing effects and poor adaptability to cargo of different sizes and weights, making it difficult to achieve uniform force distribution and prone to rope loosening during vehicle movement; secondly, traditional barrier bars and similar structures are mostly fixed installations, unable to be flexibly adjusted according to the actual height, width, and other dimensions of the cargo, making them ineffective in preventing falls from oversized, overweight, or irregularly shaped cargo, with limited protective range and strength.

[0005] Therefore, those skilled in the art have provided a road freight transport anti-fall mechanism to solve the problems mentioned in the background art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides:

[0007] A road freight transport anti-fall mechanism includes: two assembly frames, each of which is equipped with an adjustment structure, and the adjustment structure is detachably installed on the freight truck bed;

[0008] The assembly frame has an inner adjustment groove on its inner side, and a worm gear plate is fixed inside the inner adjustment groove.

[0009] The adjustment structure includes a mounting bracket movably sleeved on the assembly frame, an assembly shaft fixedly mounted on the inner side of the mounting bracket, a transmission shaft rotatably mounted on the inner side of the assembly shaft, and a worm gear meshing with a worm wheel plate fixed on the outer wall of the transmission shaft.

[0010] Preferably, a helical gear one is fixed to the bottom outer wall of the drive shaft, and helical gear one meshes with helical gear two.

[0011] Preferably, a transmission rod is fixed to the outer side of the helical gear two and rotates inside the mounting bracket, and a transmission wheel is fixed to the end of the transmission rod away from the helical gear two.

[0012] Preferably, the assembly frame has an inner groove on its inner side, and an inner sliding plate is slidably disposed inside the inner groove, with a steel wire rope fixed on the inner sliding plate.

[0013] Preferably, the assembly frame has through slots on both sides, and a positioning frame that is fixed to the inner slide plate is provided on the outside of the through slots.

[0014] Preferably, the inner walls on both sides of the positioning frame are screwed together with locking bolts.

[0015] Preferably, the top of the assembly frame is fixed with a top arc frame, and the wire rope is connected between the two assembly frames.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] In this invention, the inner slide plate in the inner groove of the assembly frame can be slidably adjusted, driving the steel wire rope to extend and retract synchronously. Combined with the fixing effect of the positioning frame and the locking bolt, the protective span between the two assembly frames can be quickly adjusted according to the width of the goods. Whether it is small scattered goods or large whole goods, precise protection can be achieved through adjustment, which solves the limitations of traditional structure anti-fall frames.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The examples of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example: Please refer to Figures 1-6 This embodiment provides a road freight transport anti-fall mechanism, including: two assembly frames 1, each of the two assembly frames 1 is equipped with an adjustment structure 2, and the adjustment structure 2 is detachably installed on the freight truck bed; an inner adjustment groove 3 is opened on the inner side of the assembly frame 1, and a worm gear plate 4 is fixed inside the inner adjustment groove 3.

[0030] The adjustment structure 2 includes a mounting bracket 201 movably sleeved on the assembly frame 1, and an assembly shaft 202 is fixedly mounted on the inner side of the mounting bracket 201. A transmission shaft 203 is rotatably mounted on the inner side of the assembly shaft 202. A worm 204 that meshes with the worm gear plate 4 is fixed on the outer wall of the transmission shaft 203. A helical gear 205 is fixed on the bottom outer wall of the transmission shaft 203. The helical gear 205 meshes with a helical gear 206. A transmission rod 207 that rotatably resides inside the mounting bracket 201 is fixed on the outer side of the helical gear 206. A transmission wheel 208 is fixed at the end of the transmission rod 207 away from the helical gear 206.

[0031] The assembly frame 1 has an inner groove 5 on its inner side, and an inner slide plate 7 is slidably arranged inside the inner groove 5. A steel wire rope 6 is fixed on the inner slide plate 7. Both sides of the assembly frame 1 have through grooves, and a positioning frame 8 fixed to the inner slide plate 7 is arranged outside the through grooves. The inner walls of both sides of the positioning frame 8 are screwed with locking bolts 9. A top arc frame 10 is fixed at the top of the assembly frame 1, and the steel wire rope 6 is connected between the two assembly frames 1.

[0032] The working principle of the above embodiments is as follows:

[0033] The adjustment structure 2 is movably mounted on the assembly frame 1 via the mounting bracket 201; the drive shaft 203 rotates inside the assembly shaft 202, driving the worm gear 204 fixed on its outer wall to mesh with the worm wheel plate 4 fixed on the inner side of the assembly frame 1, thereby realizing the relative position adjustment between the assembly frame 1 and the cargo truck bed.

[0034] The helical gear 205 at the bottom of the drive shaft 203 meshes with the helical gear 206, which converts the rotation direction and transmits it to the drive rod 207; a drive wheel 208 is fixed at one end of the drive rod 207, which is used to further transmit power or connect to an external drive device.

[0035] The inner side of the assembly frame 1 is provided with an inner groove 5, along which the inner slide plate 7 slides; the steel wire rope 6 is fixed on the inner slide plate 7, and the displacement of the inner slide plate 7 in the inner groove 5 is controlled by adjusting the transmission of the adjustment structure 2, thereby adjusting the tension and position of the steel wire rope 6.

[0036] The positioning frame 8 is connected to the inner slide plate 7 and passes through the through slot on the side of the assembly frame 1; by tightening the locking bolt 9, the positioning frame 8 and the inner slide plate 7 can be fixed in the required position to ensure that the wire rope 6 remains stable during transportation;

[0037] Two assembly frames 1 are connected by steel wire ropes 6, and a top arc frame 10 is provided on top to enhance structural strength; during cargo transportation, the mechanism forms a protective barrier through the tensioned steel wire ropes 6 to prevent cargo from falling from the side of the truck bed.

[0038] Assembly plates 209 are fixed on both sides of the assembly frame 1;

[0039] The assembly plate 209 of the two assembly frames 1 is installed on the outer wall of the cargo truck bed through the adjustment structure 2. The two sets of assembly frames 1 can be connected by adjusting the position of the transmission rod 207 on the inner side of the assembly frame 1 and locking it with the locking bolt 9. The two sets of assembly frames 1 can be assembled according to the width between the cargo truck beds.

[0040] Furthermore, the height of the assembly frame 1 can be adjusted by manually rotating the drive shaft 203. The rotation of the drive shaft 203 drives the drive rod 207, which in turn drives the helical gear 206. The rotation of the helical gear 206 meshes with the helical gear 205, causing the helical gear 205 to rotate and drive the drive shaft 203 to rotate. This causes the worm gear 204 to rotate and mesh with the worm wheel plate 4 on the inner side of the assembly frame 1, allowing the height of the assembly frame 1 to be adjusted along the mounting frame 201, which is beneficial for securing the goods inside the truck bed.

[0041] Furthermore, after multiple sets of assembly racks 1 are assembled, tarpaulins can be placed and secured on them, which facilitates the covering and protection of goods.
