Description

Technical Field

[0001] This application relates to the field of vehicle traffic management, and in particular to a telescopic barrier robotic arm. Background Technology

[0002] In the field of vehicle access management, barrier gate systems, as key equipment for controlling vehicle entry and exit, have been widely used in scenarios such as highway toll stations, residential community entrances and exits, and parking lots. The barrier gate arm, as the core component of the barrier gate system that realizes the physical blocking and release functions, directly affects the system's operating efficiency and maintenance costs due to its connection stability and ease of assembly and disassembly with the barrier gate machine.

[0003] In existing technologies, the connection between the barrier arm and the barrier gate machine typically employs a fixed installation structure. Specifically, the end of the barrier arm is fixedly connected to the drive shaft of the barrier gate machine using rigid connectors such as bolts and clips. Some structures further strengthen the connection by welding or gluing to ensure that the barrier arm does not easily detach under high-frequency lifting movements and external environmental conditions (such as wind or minor vehicle collisions). While this connection method meets basic structural stability requirements, it suffers from a significant drawback in terms of ease of assembly and disassembly.

[0004] When a barrier gate arm becomes deformed or damaged due to accidental impact and needs replacement, or when it needs to be disassembled for maintenance, operators must use specialized tools such as wrenches and screwdrivers to remove the fixed connecting parts one by one. For some welded or glued structures, destructive disassembly may even be required. This is not only time-consuming and labor-intensive, extending maintenance downtime and affecting vehicle traffic efficiency, but also prone to causing secondary damage to the barrier gate's drive shaft or other related components during disassembly, increasing additional maintenance costs. Furthermore, the fixed connection structure makes the replacement and maintenance of the barrier gate arm require a high level of skill from operators, necessitating professional personnel, further increasing labor costs.

[0005] In summary, the existing connection method between the barrier gate arm and the barrier gate machine cannot achieve quick assembly and disassembly, resulting in poor maintenance convenience and high overall costs, making it difficult to meet the needs of efficient maintenance and low-cost operation in practical applications.

The lever arm locking seat is located at one end of the main lever arm. A first threaded tube is provided on the lever arm locking seat. A spring piece is integrally connected around the inner diameter of the first threaded tube at the end of the first threaded tube. The inner diameter of the lever arm locking nut is the same as the outer diameter of the first threaded tube. The inner diameter of one end of the lever arm locking nut is reduced to be the same as the outer diameter of the telescopic lever arm.

[0015] In one possible implementation, the quick-release lever includes a rotary folding mechanism.

[0016] The beneficial effects of this utility model are: This technical solution, through the synergistic design of a telescopic and quick-release structure, enables rapid repair and significantly reduces costs when the barrier gate arm malfunctions. Specifically, the telescopic structure allows the arm length to be adjusted according to actual needs, avoiding the need for complete replacement due to a single fixed length and reducing component wear.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] specifically refer to Figure 1 , Figure 1 This diagram shows the main structure of the telescopic barrier robot arm according to an embodiment of this application.

[0026] The utility model of this application is a telescopic barrier mechanical arm, which is applied to a barrier gate. Its structure includes a main arm 101, an arm locking assembly 102, and a telescopic arm 103. The main arm 101 is a hollow cylinder, and arm locking seats are provided at both ends of the main arm 101; specifically refer to Figure 2 , Figure 2 This diagram shows the main structure of the lever arm locking assembly device according to an embodiment of this application.

[0027] The lever arm locking assembly 102 includes a lever arm locking seat 201 and a lever arm locking nut 202. The lever arm locking seat 201 is located at one end of the main lever arm 101. A first threaded tube is provided on the lever arm locking seat 201. A spring piece is integrally connected around the inner diameter of the first threaded tube at the end of the first threaded tube. The inner diameter of the lever arm locking nut 202 is the same as the outer diameter of the first threaded tube. The inner diameter of one end of the lever arm locking nut 202 is reduced to be the same as the outer diameter of the telescopic lever arm 103. The telescopic arm 103 is a hollow cylinder, and the outer diameter of the telescopic arm 103 is equal to the inner diameter of the main arm 101.

[0028] Through the nested structure of the main arm and the telescopic arm, as well as the design of the arm locking assembly, the telescopic function of the barrier arm is realized. The arm length can be adjusted according to actual needs, improving the applicability of the barrier gate in different scenarios. The cooperation of the spring and the locking nut can firmly lock the telescopic arm, ensuring that it will not loosen during use and guaranteeing the stability of the barrier gate's blocking and passage functions.

[0029] specifically refer to Figure 3 , Figure 3 This diagram illustrates the connection structure between a lever arm locking seat and a main lever arm according to an embodiment of this application.

[0030] In one possible implementation, the base position where the lever arm locking seat 201 connects to the main lever arm 101 is provided with a resilient locking hook 301, and the main lever arm 101 is provided with a hook groove 302 that matches the position of the resilient locking hook. The cooperation between the resilient locking hook and the hook groove makes the connection between the lever arm locking seat and the main lever arm more convenient, allowing for quick installation or disassembly without the need for tools, improving the efficiency of the barrier gate maintenance, while ensuring the firmness of the connection.

[0031] specifically refer to Figure 4 , Figure 4 This diagram illustrates the connection structure between a lever arm locking seat and a main lever arm according to an embodiment of this application.

[0032] In one possible implementation, the base position where the lever arm locking seat 201 connects to the main lever arm 101 is provided with a second threaded tube 401 having the same inner diameter as the main lever arm 101, and the main lever arm 101 is provided with a thread 402 having the same outer diameter as the second threaded tube. This threaded connection makes the connection between the lever arm locking seat and the main lever arm tighter and more stable, capable of withstanding greater external forces, suitable for scenarios requiring high connection strength, and also facilitates disassembly and maintenance.

[0033] In one possible implementation, the main arm 101 includes a limiting device 104 for restricting the movement distance of the telescopic arm 103. The limiting device prevents the telescopic arm from over-extending, avoiding it from detaching from the main arm or being damaged due to over-extending, thus ensuring the normal use and safety of the barrier robot arm.

[0034] In one possible implementation, the main arm 101 is made of metal.

[0035] In one specific embodiment, the main arm 101 is made of 6063 aluminum alloy, which has good corrosion resistance and mechanical strength, and is lightweight, making it suitable for scenarios where the barrier gate frequently rises and falls, effectively reducing the load on the barrier gate's drive system. The surface is anodized, forming a dense oxide film on the main arm surface, enhancing its wear resistance and weather resistance, allowing it to withstand harsh outdoor environments such as humidity and acid rain, extending the service life of the main arm. It is suitable for scenarios with high traffic volume and frequent use, such as highway toll stations. The aluminum alloy main arm ensures structural strength while reducing overall weight, improving the operating efficiency of the barrier gate.

[0036] In one specific embodiment, the main boom 101 is made of 304 stainless steel, which has excellent corrosion resistance and oxidation resistance. It is not prone to rusting in humid environments or environments with corrosive gases, ensuring long-term stable operation of the main boom. The hollow cylindrical structure of the main boom employs a seamless welding process to ensure a smooth interior and prevent obstruction during the extension and retraction of the boom. Simultaneously, the welded areas are polished to improve aesthetics and rust resistance. Suitable for highly corrosive environments such as coastal areas and chemical industrial parks, the 304 stainless steel main boom effectively resists salt spray and chemical gas corrosion, reducing maintenance costs.

[0037] In one specific embodiment, the main arm 101 is made of Q235 carbon steel, which is high in strength and inexpensive, making it suitable for scenarios requiring high strength. The wall thickness of the main arm can be adjusted according to actual needs; for example, in the entrance of a large parking lot, the wall thickness can be increased to improve impact resistance. The surface is treated with hot-dip galvanizing, which effectively prevents the steel from rusting. A zinc-iron alloy layer is formed between the hot-dip galvanized layer and the steel, with strong adhesion and not easy to fall off, ensuring that the main arm maintains good performance even after many years of outdoor use. It is suitable for places with frequent access by large vehicles, such as industrial plants and logistics parks. The Q235 carbon steel main arm has high strength and impact resistance, effectively blocking accidental impacts from large vehicles and ensuring the safe operation of the barrier gate.

[0038] In one possible implementation, the telescopic arm 103 is made of plastic.

[0039] In one specific embodiment, the telescopic arm 103 is made of polycarbonate. Polycarbonate has high strength and toughness, with high impact strength and high tensile strength, and can withstand a certain amount of external impact without easily breaking. At the same time, PC material has good transparency, and color masterbatch can be added as needed to produce telescopic arms of different colors to meet aesthetic requirements.

[0040] In one specific embodiment, an anti-slip texture is provided on the outer surface of the telescopic arm to increase the friction between the telescopic arm and the locking nut, preventing the telescopic arm from loosening during use. The anti-slip texture can take various forms, such as straight lines or a mesh pattern, and can be selected according to actual needs.

[0041] The above embodiments are suitable for scenarios with high requirements for aesthetics, such as residential communities and commercial parking lots. The telescopic arm made of PC material not only has good performance, but also can coordinate with the appearance design of the barrier gate, improving the overall aesthetics.

[0042] In one specific embodiment, the telescopic boom 103 is made of nylon. Nylon has excellent wear resistance and self-lubricating properties, and a low coefficient of friction, which can reduce wear between the telescopic boom and the main boom, extending its service life. It also has good chemical corrosion resistance, resisting the erosion of oil, water, and common solvents. Furthermore, nylon is lightweight and has a low density, which can reduce the overall weight of the barrier gate.

[0043] In one specific embodiment, reinforcing ribs are provided on the inner wall of the telescopic arm to improve its rigidity and stability and prevent deformation during telescopic movement. The number and distribution of the reinforcing ribs can be optimized according to the length and diameter of the telescopic arm.

[0044] The above embodiments are applicable to scenarios that require frequent extension and retraction, such as automatic gate machines at highway toll stations. The nylon telescopic arm can reduce friction, lower noise, and improve the operational stability of the gate machine.

[0045] In one specific embodiment, the telescopic boom 103 is made of ABS material. ABS has excellent overall performance, with good impact resistance, heat resistance, low-temperature resistance, and chemical corrosion resistance, allowing it to be used normally within a variety of temperature ranges. ABS material also has excellent processing properties, enabling it to be injection molded into telescopic booms of various complex shapes to meet different design requirements.

[0046] In one specific embodiment, wear-resistant sleeves are provided at both ends of the telescopic arm. The wear-resistant sleeves are made of polytetrafluoroethylene (PTFE) to further improve the wear resistance and self-lubricating properties of the telescopic arm. An interference fit is used between the wear-resistant sleeves and the telescopic arm to ensure a secure installation.

[0047] The above embodiments are applicable to regions with varying climate conditions, such as cold northern regions and hot southern regions. The ABS telescopic arm can maintain good performance under different temperature environments, ensuring the normal operation of the barrier gate.

[0048] The following is a detailed reference. Figure 5 , Figure 5 This diagram illustrates the connection relationship between the main arm and the barrier gate in an embodiment of this application.

[0049] In one possible implementation, the main arm 101 is provided with a first connecting hole for rotatable connection with the barrier gate and a matching first bolt 501. This achieves a rotatable connection between the main arm and the barrier gate, enabling the barrier arm to move up and down around the barrier gate, thus meeting the functional requirements of the barrier gate for blocking and allowing vehicles to pass.

[0050] In one possible implementation, the main arm 101 is provided with a second connecting hole for connection to the hydraulic rod of the barrier gate and a second bolt 502 for threshold matching. Through connection with the hydraulic rod of the barrier gate, the lifting and lowering of the barrier arm is driven by the power of the hydraulic system, making the lifting process smoother and more reliable, capable of withstanding larger loads, and improving the operating efficiency and stability of the barrier gate.

[0051] In one possible implementation, the first bolt 501 and the second bolt 502 are equipped with quick-release levers 503. The quick-release levers allow for rapid disassembly and installation of the connecting bolts between the main arm and the barrier gate, requiring no tools or only simple operation. This significantly improves the efficiency of barrier gate maintenance and replacement of the barrier arm, reduces maintenance downtime, and lowers labor costs.

[0052] In one possible implementation, the quick-release lever includes a rotating folding mechanism. This mechanism allows the quick-release lever to be folded away when not in use, saving space and preventing disruption to the normal operation of the barrier gate. When bolts need to be removed or installed, the quick-release lever can be unfolded by rotating it, facilitating operation and further improving convenience.

[0053] In one specific embodiment, when it is necessary to disassemble or install the first bolt 501 and the second bolt 502 connecting the main arm and the barrier gate, the operator only needs to align the end of the quick-release lever body with the hexagonal groove with the bolt head, press down firmly to make the groove tightly engage with the bolt head, and then easily loosen the bolt by rotating the quick-release lever body, thus achieving quick disassembly or installation. Because the quick-release lever body is made of aluminum alloy, it has high strength and can withstand large torque, ensuring that it will not deform or be damaged during operation. The rubber anti-slip grip design makes it more comfortable for the operator to hold the quick-release lever, preventing slippage and improving the convenience and safety of operation.

[0054] The above embodiments enable the rapid disassembly and installation of the bolts connecting the main arm and the barrier gate. Operators do not need to carry professional wrenches, screwdrivers, or other tools; they only need to use the quick-release lever to complete the operation, greatly shortening the time for maintaining and replacing the barrier gate's robotic arm. For example, in the traditional way, replacing a barrier gate's robotic arm may take 30 minutes, while with the quick-release lever, it only takes about 5 minutes, greatly improving the maintenance efficiency of the barrier gate, reducing maintenance downtime, and lowering labor costs.

[0055] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
