Description

Technical Field

[0001] This utility model relates to the field of semi-trailer safety protection technology, and in particular to a safety protection device for semi-trailer operation along the edge. Background Technology

[0002] In modern logistics and transportation systems, semi-trailers are core equipment. From the distribution of daily consumer goods to the transportation of building materials needed for large-scale engineering projects, semi-trailers are ubiquitous. They play an irreplaceable role in key areas such as cargo handling and engineering operations, and are a crucial link in ensuring the stable operation of the social economy.

[0003] However, over a long period of use, people have gradually discovered that traditional semi-trailers pose significant safety hazards when operating along borders: (1) In loading and unloading operations, workers need to frequently operate on the edge of the vehicle. Due to the lack of effective protective measures, they are prone to falling off the edge of the vehicle if they are not careful, which poses a serious threat to their personal safety. (2) Existing mechanical adjustment devices for semi-trailers generally adopt a gear and rack structure. Although this structure can achieve a certain degree of height adjustment to meet different operational needs, after long-term use, the frequent friction between the gears will cause a gap of 2-3mm, resulting in excessive shaking of the guard rod. Therefore, there is an urgent need for a safety device that combines protective performance and ease of operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a safety protection device for semi-trailer operation along the edge.

[0005] The present invention adopts the following technical solution: A safety protection device for semi-trailer operating along the edge includes an adjustable height protective component, a telescopic component, and a fixing component; The height-adjustable protective assembly consists of two parallel, vertically arranged protective rods, which are installed on the side of the vehicle body via a fixing assembly. The telescopic assembly includes a steel wire rope, a fixed pulley, and a rope guide; The first guard rod is equipped with a wire rope fixing seat, the top of the second guard rod is equipped with a fixed pulley, and the second guard rod is equipped with a rope guide. The wire rope of the telescopic component passes through the fixed pulley and forms a closed loop with the rope guide.

[0006] Preferably, the rope guide is a manual rope guide with a self-locking function.

[0007] Preferably, the rope guide is installed on the rope guide mounting platform located at the upper third of the second guard rod.

[0008] Preferably, the rope guide is equipped with an anti-loosening ratchet structure, which can adjust the stroke range from 0 to 12m.

[0009] Preferably, the fixing assembly includes an upper locking device and a lower sleeve device. The upper locking device and the lower sleeve device are respectively provided with U-shaped slots. The U-shaped slot of the upper locking device is locked to the side of the vehicle body and the protective rod is fixed by U-bolts. The lower sleeve device is provided with a sleeve, and the bottom end of the protective rod is sleeved and fixed in the sleeve and locked to the bottom of the vehicle body by the U-shaped slot of the lower sleeve device.

[0010] Preferably, the U-shaped grooves of the upper locking device and the lower sleeve device are provided with rubber liners.

[0011] Preferably, the sleeve and the protective rod are fitted with a clearance of ≤1mm.

[0012] Preferably, the protective components, telescopic components, and fixing components are all made of stainless steel.

[0013] The beneficial effects of this utility model are: (1) Dual-mode protection: height / width dual adjustment to adapt to different vehicle models and cargo specifications; (2) Safety protection is achieved when the operator performs edge work; (3) The composite fixed guard rod method enhances the stability of the guard rod. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram: 1. First adjustable guard rod; 2. Second adjustable guard rod; 3. Steel wire rope; 4. Fixed pulley; 5. Manual rope guide; 6. First U-shaped slot; 7. Second U-shaped slot; 8. U-bolt; 9. Fixing sleeve. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figure 1 As shown, a safety protection device for semi-trailer side-operation includes a first adjustable guard rod 1; a second adjustable guard rod 2; a wire rope 3; a fixed pulley 4; a manual rope guide 5; a first U-shaped slot 6; a second U-shaped slot 7; a U-bolt 8; and a fixing sleeve 9. The first adjustable guard rod 1 and the second adjustable guard rod 2 are respectively fixed to one side of the vehicle body through the first U-shaped slot 6. The first U-shaped slot 6 is provided with U-shaped bolt holes for easy fixing of the upper guard rod. The second U-shaped slot 7 is secured to the lower part of the vehicle body and is provided with a sleeve for easy fixing of the guard rod. The first adjustable guard rod 1 is provided with a wire rope fixing seat, and the fixed pulley assembly is installed on the top of the second adjustable guard rod 2. The wire rope 3 is connected to the manual rope guide 5 through the fixing seat and the fixed pulley 4 to realize the horizontal extension and retraction of the guard rod.

[0016] In practical applications, such as Figure 1 As shown, the first U-shaped slot 6 of the upper locking device is engaged with the side of the vehicle body, and the second U-shaped slot 7 is engaged with the bottom of the vehicle body. Then, the first adjustable guard rod 1 is aligned with the sleeve of the second U-shaped slot 7, thus providing lower-level fixation. The first adjustable guard rod 1 is fixed with U-bolts 8, achieving upper-level fixation. The first adjustable guard rod 1 is fixed to the rear of the vehicle body. Using the steel wire rope 3 and the fixed pulley 4, the second adjustable guard rod 2 is moved horizontally to a suitable position and fixed using the same method as fixing the first adjustable guard rod 1. When it is necessary for a person to stand on the semi-trailer and work along the edge, the safety hook is attached to the steel wire rope 3 for safety protection.
