Description

Technical Field

[0001] This utility model relates to the field of video surveillance technology, specifically to a multi-axis anti-vibration buffer pan-tilt camera device for container spreaders. Background Technology

[0002] Currently, most projects use video surveillance equipment for observing stable operation or static observation of a specific area. Therefore, the structural strength and impact / collision resistance requirements for this equipment are not high. Consequently, the casings of most surveillance equipment on the market are commonly made of plastic, cold-rolled steel, or profiles. However, in special circumstances, surveillance equipment needs to be installed in high-impact, high-collision locations, such as the locking positions of spreader cranes on quay cranes or yard cranes. When the locking head engages with the container, it initially plunges downwards from a high position, directly entering the container's locking hole. Ideally, the engagement between the locking head and the locking hole is smooth, but due to the speed and weight of the locking head, it directly impacts the container, causing significant impact to the surveillance equipment installed near the locking head. In less than ideal situations... In situations where the lock head and lock hole are misaligned excessively, the lock head may lurch downwards, directly impacting the outside of the container or squeezing into the lock hole. This could then cause a strong collision with the monitoring equipment installed near the lock head. During the initial installation of the monitoring equipment, it is necessary to adjust the camera angle to meet the different driver's requirements. However, most commercially available monitoring equipment is directly welded to the side wall of the spreader. Adjusting the angle after welding requires recutting and re-welding, which is very inconvenient. Therefore, using commercially available monitoring equipment is unsuitable for high-impact, high-collision environments requiring adjustable angles due to its relatively weak casing material and structural design, as well as the inconvenience of angle adjustment. Thus, there is an urgent need for a monitoring device that can operate stably and with an adjustable angle in high-impact, high-collision environments. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of existing technologies by providing a container spreader multi-axis anti-vibration buffer pan-tilt camera device that is simple in structure, reasonable in design, and easy to use. This device can solve the problems that common monitoring equipment on the market cannot meet stable working conditions and cannot easily adjust the camera angle in high-impact and high-collision environments.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes an anti-collision frame and a camera device, wherein the anti-collision frame is fixedly installed on the front side of the lifting device, and the camera device is installed inside the anti-collision frame;

[0005] The camera device includes:

[0006] The device has a spherical outer shell, which is disposed inside the anti-collision outer frame, and the spherical outer shell has an installation cavity inside.

[0007] The base is installed on the upper side of the mounting cavity;

[0008] A pinhole camera, wherein the pinhole camera is disposed in the mounting cavity and the probe section of the pinhole camera passes through the base;

[0009] A fixed tile is fixedly installed inside the mounting cavity, and a pinhole camera is inserted inside the fixed tile;

[0010] Tail spring, the tail spring is sleeved on the pinhole camera, and the tail spring is set on the upper side of the fixing tile, and the upper end of the tail spring is set to abut against the base.

[0011] A top spring is sleeved on the pinhole camera and is located on the lower side of the fixing tile.

[0012] The above technical solution uses a tail spring and a top spring to suspend and fix the pinhole camera inside the spherical shell of the device. Then, a fixing tile is used to fix the pinhole camera inside the spherical shell of the device, and a base is used to fix the spring at the top.

[0013] As a further improvement of this utility model, a sealing ring is provided at the bottom of the mounting cavity, and the bottom end of the top spring abuts against the inside of the sealing ring.

[0014] The above technical solution design uses a sealing ring to seal the entire camera device.

[0016] The above technical solution design connects the spherical outer shell of the device with the anti-collision outer frame.

[0017] As a further improvement of this utility model, a safety chain is provided on the outer side of the spherical shell of the device, and the other end of the safety chain is flexibly connected to the vicinity of the lock.

[0018] Through the above technical solution design, the safety chain is flexibly connected to the vicinity of the lock head to support the camera device. It will not fall directly but will be suspended near the lock head, thus preventing personal injury and secondary damage to nearby equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The top spring and the tail spring are fixed at both ends of the pinhole camera respectively. When strong impact and collision loads are applied to the camera, they absorb the corresponding kinetic energy for the camera, protect the camera from damage, and improve the stability of the camera in high impact and collision environments.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1:

[0029] Please see Figures 1-3 In this embodiment, it includes a crash protection frame 1 and a camera device 2. The crash protection frame 1 is welded and fixed to the front side of the lifting device 3, and the camera device 2 is installed inside the crash protection frame 1.

[0030] The camera device 2 includes:

[0031] The device has a spherical outer shell 4, which is located inside the anti-collision frame 1. The device has a mounting cavity 5 inside the spherical outer shell 4. The anti-collision frame 1 has a pressure plate 12 inside, and the pressure plate 12 is connected to the device has a spherical outer shell 4 by bolts. The device has a safety chain 13 on the outside of the spherical outer shell 4, and the other end of the safety chain 13 is flexibly connected to the vicinity of the lock head.

[0032] Base 6, which is installed on the upper side of the mounting cavity 5;

[0033] The pinhole camera 7 is disposed in the mounting cavity 5, and the probe section of the pinhole camera 7 passes through the base 6.

[0034] The fixed tile 8 is fixedly installed inside the mounting cavity 5, and the pinhole camera 7 is inserted through the fixed tile 8;

[0035] Tail spring 9, the tail spring 9 is sleeved on pinhole camera 7, and the tail spring 9 is set on the upper side of fixed tile 8, and the upper end of tail spring 9 is in contact with base 6.

[0036] A top spring 10 is sleeved on the pinhole camera 7 and is located on the lower side of the fixing tile 8; a sealing ring 11 is provided at the bottom of the mounting cavity 5 and the bottom end of the top spring 10 abuts against the sealing ring 11.

[0037] Through the above technical solution design, the pinhole camera 7 is suspended and fixed inside the spherical shell 4 of the device using the tail spring 9 and the top spring 10. Then, the pinhole camera 7 is fixed inside the spherical shell 4 of the device using the fixing tile 8. The upper part is fixed with the spring using the base 6. The sealing ring 11 seals the entire camera device 2. The safety chain 13 is flexibly connected to the vicinity of the lock head to support the camera device 2. It will not fall directly but will be suspended near the lock head, so as not to cause personal injury or secondary damage to nearby equipment.

[0038] In using this invention, the spherical shell 4 of the device employs a suspended fixing structure, suspending and fixing the pinhole camera 7 inside the spherical shell 4. When a strong impact or collision with a maximum acceleration of 100g acts on the spherical shell 4, the energy can be absorbed by the buffer device. The top spring 10 and the tail spring 9 of the buffer device are in a pre-compressed state, a "pre-loaded" state, which can reduce dynamic displacement during impact and improve response speed. The top spring 10 and the tail spring 9 are made of materials with high elastic modulus and high fatigue strength. Through pre-compression, the system damping is moderate, and the impact... If the energy is within the spring's storage range, the semi-compressed spring can quickly return to its original position, achieving system stability. Through relevant gap design, it is ensured that the pinhole camera 7 will not collide with the outer casing, further guaranteeing the safety of the pinhole camera 7. The structure employs a camera device 2 and a shock-resistant frame 1. The pinhole camera 7 is installed inside the camera device 2, which in turn is installed inside the shock-resistant frame 1. The shock-resistant frame 1 is welded from 10mm thick Q235 steel plate. The camera device 2 is secured to two M8×80 bolts via two pressure plates 12 with hemispherical openings, ensuring the camera device... Part 2, together with the anti-collision frame 1, forms a single unit. The anti-collision frame 1 is directly welded near the lock head, and after welding, a protective paint is applied to ensure that even if strong impacts and collisions directly act on the anti-collision frame 1, the camera device 2 is directly protected from damage. The anti-collision frame 1 is directly connected to the main machine by welding, increasing structural strength. Furthermore, since the camera device 2 is bolted to the anti-collision frame 1 via a spherical surface, the bolts can be loosened to manually adjust the camera's observation angle according to the on-site angle requirements of the lifting device 3. The adjustable angle of the camera meets the on-site angle adjustment needs of the lifting device 3, reducing installation complexity. Difficulty: In extreme cases, when strong impacts and collisions directly act on the outer shell, the weld between the outer shell and the lock head may break. The anti-collision frame 1 is designed with a sliding slope. When impacts and collisions are applied to the anti-collision frame 1, the upward impact force is directly dissipated through the sliding slope, thereby reducing the force. In addition, a safety chain 13 is added between the camera device 2 and the anti-collision frame 1. In extreme cases, when the camera device 2 falls, the safety chain 13 is also flexibly connected to the area near the lock head, so the camera device 2 will not fall directly but will be suspended near the lock head, preventing personal injury and secondary damage to nearby equipment.

[0039] Compared with the prior art, the beneficial effects of this utility model are:

[0040] 1. The top spring 10 and the tail spring 9 are fixed at both ends of the pinhole camera 7 respectively. When strong impact and strong collision loads are applied to the camera, they absorb the corresponding kinetic energy for the camera, protect the camera from damage, and improve the stability of the camera in high impact and strong collision environments.

[0041] 2. A safety chain 13 device is added to the anti-collision outer frame 1 to provide a safety guarantee for the operation of the monitoring equipment.

[0042] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
