Description

Technical Field

[0001] This utility model relates to the technical field of bollard auxiliary equipment, specifically a detachable fastening device for bollards. Background Technology

[0002] In ports, docks, and other ship berthing and logistics transportation sites, mooring bollards serve as key fixing points for mooring lines. They directly bear the tension and impact forces generated by ships due to wind, waves, currents, and operations. The reliability of their fixing is directly related to ship berthing safety, operational efficiency, and facility integrity.

[0003] Currently, the fixing of mooring bollards mainly adopts traditional rigid connection methods, including welding, concrete pouring, and multi-bolt rigid fixing. Welding fixation involves welding the bollard to the bottom of the foundation with embedded parts, providing high initial connection strength but making it non-removable. Concrete pouring fixation integrates the bollard with the foundation, offering strong resistance to external forces but lacking adjustability. While multi-bolt fixing offers some removability, the bolts are prone to corrosion and jamming after long-term use, making disassembly difficult. These traditional methods have significant drawbacks: disassembly requires destructive operations such as cutting, smashing, or forceful loosening, which is time-consuming and labor-intensive, affecting normal port operations; the fixed position cannot be adjusted, resulting in poor flexibility; maintenance costs are high, and the bollard cannot be used during maintenance.

[0004] Therefore, to ensure the structural stability and operational safety of mooring bollards during long-term use, they must be reliably connected to the ground, wharf concrete foundation, or specific base through specialized fixing methods. This allows the mooring bollards to continuously and stably withstand various external forces generated when ships are moored, avoiding various risks caused by fixing failure and ensuring the normal operation of ports and wharves. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a detachable fastening device for mooring bollards that enables rapid disassembly and assembly without destructive operation, shortens the maintenance and replacement cycle, and reduces disruption to normal port berth operations.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: a detachable fastening device for a bollard, including a base, with a fixed clamp and a movable clamp symmetrically arranged on the top surface of the base. The fixed clamp is fixed on the top surface of the base, and the movable clamp is movably arranged on the top surface of the base. An arc-shaped clamping surface for clamping the mooring bollard is provided on a pair of parallel vertical surfaces where the fixed clamp and the movable clamp are close to each other. A telescopic power mechanism is fixedly installed on the top surface of the base. The telescopic end of the telescopic power mechanism is fixedly connected to the movable clamp, thereby driving the movable clamp to move closer to or away from the fixed clamp. A slide is provided on the base between the fixed clamp and the movable clamp. A slider is fixed on the bottom surface of the movable clamp and placed in the slide. The opening direction of the slide is parallel to the extension and retraction direction of the telescopic power mechanism, so as to guide the movement direction of the movable clamp. Elastic elements are fixedly provided on a pair of parallel vertical surfaces that are close to each other, and a buffer is fixedly provided on the other end of the elastic element. The buffer is located below the arc-shaped clamping surface.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned detachable fastening device for mooring bollards has several bolt placement holes on the base.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned detachable fastening device for mooring bollards has anti-slip texture on the arc-shaped clamping surface.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned detachable fastening device for mooring bollards has two arc-shaped clamping surfaces symmetrically provided on both the fixed clamp and the movable clamp.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned detachable fastening device for mooring bollards has two parallel sliding tracks, and each track has a slider fixed to the bottom surface of the movable clamp.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned detachable fastening device for mooring bollards has a hollow guide column vertically fixed on a pair of parallel vertical surfaces that are close to each other, the buffer member has a guide rod fixed on its side wall, the guide rod is placed inside the guide column, one end of the elastic element is fixed on the inner wall of the guide column, and the other end is fixed on the side wall of the guide rod.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are: (1) By using the telescopic power mechanism to drive the movable clamp to approach or move away from the fixed clamp, the mooring bollard is clamped or loosened by the arc clamping surface between the fixed clamp and the movable clamp, so as to realize the detachable installation of the mooring bollard. This makes it very convenient for the replacement of the mooring bollard. The mooring bollard can be disassembled without mechanical damage, which is highly practical. (2) The arc-shaped clamping surface of the assembly used to clamp the bollard has anti-slip texture, which improves the clamping stability of the bollard to a certain extent. In addition, a buffer is also configured. After the outer peripheral surface of the bollard comes into contact with the buffer, the elastic potential energy generated can react on the fixed clamp and the movable clamp, thereby buffering the sudden increase of clamping force and damage to the outer peripheral surface of the bollard. It can also absorb the impact force when the ship is moored and vibrates, avoid the gap between the clamp and the bollard, and further ensure the fixation stability. (3) A slide is provided on the base between the fixed clamp and the movable clamp. The sliding direction of the movable clamp can be guided by the slide and the slider on the movable clamp, so that the mooring pile clamping operation is more stable. Attached Figure Description

[0015] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0016] Example 1, referring to Figure 1-3 A detachable fastening device for a bollard includes a base 1, which is formed into a generally square plate structure. The base 1 has several bollard placement holes 2, the number of which can be selected according to the usage requirements. Its design purpose is to fix the base 1 to the ground. A fixed clamp 3 and a movable clamp 4 are symmetrically arranged on the top surface of the base 1. The fixed clamp 3 and the movable clamp 4 are formed into a generally square shell structure. The fixed clamp 3 is fixed to the top surface of the base 1, and the movable clamp 4 is movably arranged on the top surface of the base 1. Arc-shaped clamping surfaces 5 for clamping mooring bollards are provided on a pair of parallel vertical surfaces of the fixed clamp 3 and the movable clamp 4 that are close to each other. The arc-shaped clamping surfaces 5 on the fixed clamp 3 and the movable clamp 4 can be spliced ​​to form a cylindrical cavity structure. The arc-shaped clamping surfaces 5 have anti-slip textures (not shown in the figure). The purpose of the anti-slip textures is to increase the roughness of the inner circumference of the arc-shaped clamping surfaces 5, thereby improving the clamping stability. The structural design of the anti-slip textures can refer to the texture on the handlebars, etc., but is not limited to this. The fixed clamp 3 and the movable clamp 4 each have two symmetrical arc-shaped clamping surfaces 5, which can clamp two mooring bollards. A telescopic power mechanism 6 is fixedly provided on the top surface of the base 1. The telescopic power mechanism 6 can be a hydraulic cylinder or an electric cylinder, etc. The type can be selected according to the usage requirements. The telescopic end of the telescopic power mechanism 6 is fixedly connected to the movable clamp 4, thereby driving the movable clamp 4 to move closer to or away from the fixed clamp 3. A slide 7 is provided on the base 1 between the fixed clamp 3 and the movable clamp 4. The slide 7 is roughly square. A slider 8 is fixed on the bottom surface of the movable clamp 4 and placed in the slide 7. The slider 8 is square. The opening direction of the slide 7 is parallel to the extension direction of the telescopic power mechanism 6, so as to guide the movement direction of the movable clamp 4. There are two slides 7. The design of two slides 7 can make the movement of the movable clamp 4 more stable. The two slides 7 are parallel to each other. Each slide 7 is provided with a slider 8 fixed to the bottom surface of the movable clamp 4. Elastic elements 9 are fixedly provided on a pair of parallel vertical surfaces close to each other on the fixed clamp 3 and the movable clamp 4. The elastic elements 9 can be springs or compression springs. A buffer 10 is fixedly provided on the other end of the elastic element 9. The buffer 10 is located below the arc-shaped clamping surface 5. The buffer 10 can be a square plate structure. Its shape and size can be selected according to the usage requirements. A hollow guide post 11 is vertically fixed on a pair of parallel vertical surfaces close to each other on the fixed clamp 3 and the movable clamp 4. Its cross-section is set in a ring shape. A guide rod 12 is fixed on the side wall of the buffer 10. The guide rod 12 is a cylindrical rod structure. The guide rod 12 is placed inside the guide post 11. One end of the elastic element 9 is fixed on the inner wall of the guide post 11, and the other end is fixed on the side wall of the guide rod 12.

[0017] The working principle of the detachable fastening device for the mooring bollard in Example 1 is as follows: First, the hydraulic telescopic rod is retracted, maintaining the maximum distance between the movable clamp 4 and the fixed clamp 3 to provide operating space for inserting the mooring bollard. Then, the mooring bollard is placed on the base 1, with one side pressed tightly against the arc-shaped clamping surface 5 of the fixed clamp 3. Finally, the hydraulic telescopic rod is extended, pushing the movable clamp 4 along the slide 7 towards the fixed clamp 3 until its arc-shaped clamping surface 5 is tightly pressed against the other side of the mooring bollard. During this process, the elastic element 9 deforms under pressure, providing flexible clamping for the mooring bollard through the buffer 10, avoiding rigid impact and overload damage, thus completing the installation. When it is necessary to replace the mooring bollards periodically, the hydraulic telescopic rod can be retracted to loosen the clamped bollards. The entire process does not require any external mechanical force to forcibly dismantle the mooring bollards, saving time and effort.
