Description

Technical Field

[0001] This utility model relates to the field of logistics loading and unloading equipment technology, specifically to a movable single-sided anti-fall support for truck loading and unloading operations. Background Technology

[0002] During logistics loading operations, workers need to move and handle goods along the edges of the truck bed, posing a risk of falling from height. Traditional fall arrestors mostly use a fixed portal frame structure, which has the following drawbacks: ①Immovable: Once installed, it cannot be moved to adjust the working position, requiring repeated disassembly and reassembly, resulting in low efficiency; ②Poor versatility: The portal frame needs to span both sides of the carriage, making it unsuitable for different width vehicle models; ③Bulk structure: It is integrally welded, resulting in high transportation and storage costs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a movable single-sided anti-fall bracket for truck loading and unloading operations. It can be moved according to the working position, and can be modularly disassembled and assembled according to different vehicle models. Its height and stability are adjustable to adapt to various vehicle models and working scenarios, effectively ensuring the safety of operators.

[0004] To achieve the above objectives, the present invention proposes the following technical solution: A movable single-sided anti-fall bracket for truck loading and unloading operations includes a base, a vertical pole mounted on the base, an adjusting rod sleeved on the top of the pole, a reinforcing component, and an anti-fall component mounted on the top of the adjusting rod.

[0005] The fall arrestor assembly includes a fall arrestor column fixedly connected to the top of the adjusting rod, at least two fall arrestor crossbars horizontally arranged on the side of the fall arrestor column near the vehicle, a fall arrestor connecting rod vertically connected to each fall arrestor crossbar, at least two fall arrestor reinforcing rods, and a fall arrestor suspended on the fall arrestor connecting rod. The upper end of the fall arrestor reinforcing rod is connected to the fall arrestor crossbar, and the lower end of the fall arrestor reinforcing rod is connected to the fall arrestor column.

[0006] The adjusting rod is provided with multiple sets of first adjusting holes along its vertical length, and the upright is provided with first locking holes corresponding to the first adjusting holes. An adjusting rod fixing bolt passes through the locking hole and the selected first adjusting hole to fix the height of the adjusting rod relative to the upright, thereby driving the entire anti-fall assembly to rise and fall to adapt to truck bodies of different heights.

[0007] The base is equipped with omnidirectional casters with brakes at all four corners, allowing the bracket to be easily moved to the required work position and reliably positioned.

[0008] The reinforcing assembly includes an inner reinforcing rod and an outer reinforcing rod. The inner reinforcing rod is inclined, with its upper end connected to the upright and its lower end connected to the side of the base closest to the vehicle. The outer reinforcing rod is also inclined, with its upper end connected to the upright and its lower end connected to the side of the base furthest from the vehicle. The inner and outer reinforcing rods, together with the upright and the base, form a stable triangular support system to ensure that the single-sided support does not overturn when subjected to lateral forces.

[0009] Preferably, the fall arrestor is a self-locking differential fall arrestor used for workers' safety belts, and automatically locks to provide protection in the event of a fall.

[0010] The aforementioned fall arrestor is existing technology. The fall arrestor is a core component to ensure the safety of workers. Its working principle is as follows: internally, through a ratchet and centrifugal braking system, it remains smooth when the safety belt connecting rope is pulled out slowly and normally; once a person falls, the connecting rope is pulled quickly and violently, and the internal mechanism will trigger braking in an instant to lock the connecting rope, thereby preventing the person from falling further.

[0011] Preferably, the connection point between the upper end of the outer reinforcing rod and the upright is higher than the connection point between the upper end of the inner reinforcing rod and the upright, so as to optimize the force distribution and enhance the overall stability.

[0012] Preferably, a reinforcing tube is provided at the connection between the inner reinforcing rod and the base, and a forklift fork sleeve is provided at the reinforcing tube for easy insertion of forklift forks, so as to facilitate overall handling by forklift.

[0013] Preferably, the base has two symmetrical and outwardly inclined extension rods on the side away from the vehicle, with an inclination angle of 60~80°. The lower end of the outer reinforcing rod is connected to the extension rod, which expands the support area of ​​the base and significantly improves the anti-overturning ability.

[0014] Preferably, the upper end of the outer reinforcing rod is hinged to the upright. The outer reinforcing rod is a sleeve-type telescopic rod structure, and its length is fixed by a telescopic rod fixing bolt. The extension rod has multiple sets of second adjustment holes along its length direction, and the lower end of the outer reinforcing rod has a second locking hole corresponding to the second adjustment hole. By passing a reinforcing rod fixing bolt through the second locking hole and the selected second adjustment hole, the lower end of the outer reinforcing rod is locked at different positions on the extension rod. At the same time, the length of the outer reinforcing rod can be adjusted by adjusting the position of the telescopic rod fixing bolt, thereby adjusting the support angle and support lever arm of the outer reinforcing rod. When the fall arrester is in a higher working position, the outer reinforcing rod can be adjusted to a better support angle, thereby providing a greater support reaction force, effectively balancing the overturning moment increased due to the rise in the center of gravity, and ensuring that the support maintains equally excellent stability at all working heights.

[0015] The beneficial effects of this utility model are as follows: This invention, by installing universal casters with brakes on the base, enables the bracket to be quickly moved and precisely fixed on the work site, greatly improving work efficiency.

[0016] This utility model uses a telescopic rod and bolt holes to adjust the height of the fall arrestor. The structure is simple and reliable, and can quickly adapt to the height changes of different truck bodies.

[0017] This invention utilizes a composite triangular support system composed of inner and outer inclined reinforcing rods, which greatly enhances the anti-overturning capability of a single-sided support. The added extension rod further expands the support base, thus providing secondary reinforcement of stability. The adjustable design of the outer reinforcing rod allows it to adapt to uneven ground, significantly improving safety.

[0018] This invention saves materials and reduces manufacturing costs through its single-sided design, while its modular structure facilitates production, transportation, and on-site assembly.

[0019] By adopting the above solution, this utility model can move with the adjustment of the working position, and can be modularly disassembled and adaptively adjusted according to different vehicle models. The structure is stable and the safety is guaranteed. Attached Figure Description

[0031] The adjusting rod 6 has multiple sets of first adjusting holes along its vertical length, and the upright 5 has a first locking hole corresponding to the first adjusting hole. An adjusting rod fixing bolt 11 passes through the locking hole and the selected first adjusting hole to fix the height of the adjusting rod 6 relative to the upright 5, thereby driving the entire anti-fall assembly to rise and fall to adapt to truck bodies of different heights.

[0032] The base 1 is equipped with universal casters 3 with brakes at the four corners of its bottom, which allows the bracket to be easily moved to the required work position and reliably positioned.

[0033] The reinforcing assembly includes an inner reinforcing rod 2 and an outer reinforcing rod 4.

[0035] Subsequently, the fall arrestor 10 is suspended from the fall arrestor connecting rod 9. The worker connects their safety belt hook to the safety rope connection end of the fall arrestor 10, allowing them to work safely within the protection range of the support. In the event of an accidental fall, the fall arrestor 10 will instantly self-lock, providing safety protection for the personnel.

[0036] Second embodiment: like Figure 2 As shown, a movable single-sided anti-fall bracket for truck loading and unloading operations includes a base 1, a vertical pole 5 mounted on the base 1, an adjusting rod 6 sleeved on the top of the vertical pole 5, a reinforcing component, and an anti-fall component mounted on the top of the adjusting rod 6.

[0038] The adjusting rod 6 has multiple sets of first adjusting holes along its vertical length, and the upright 5 has a first locking hole corresponding to the first adjusting hole. An adjusting rod fixing bolt 11 passes through the locking hole and the selected first adjusting hole to fix the height of the adjusting rod 6 relative to the upright 5, thereby driving the entire anti-fall assembly to rise and fall to adapt to truck bodies of different heights.

[0039] The base 1 is equipped with universal casters 3 with brakes at the four corners of its bottom, which allows the bracket to be easily moved to the required work position and reliably positioned.

[0040] The reinforcing assembly includes an inner reinforcing rod 2 and an outer reinforcing rod 4. The inner reinforcing rod 2 is inclined, with its upper end connected to the upright 5 and its lower end connected to the side of the base 1 closest to the vehicle. The outer reinforcing rod 4 is also inclined, with its upper end connected to the upright 5 and its lower end connected to the side of the base 1 furthest from the vehicle. The inner reinforcing rod 2 and the outer reinforcing rod 4, together with the upright 5 and the base 1, form a stable triangular support system to ensure that the single-sided support does not overturn when subjected to lateral forces.

[0041] The fall arrestor 10 is a self-locking speed difference fall arrestor.

[0042] The connection point between the upper end of the outer reinforcing rod 4 and the upright rod 5 is higher than the connection point between the upper end of the inner reinforcing rod 2 and the upright rod 5, so as to optimize the force distribution and enhance the overall stability.
