Description

Technical Field

[0001] The invention relates to the technical field of shock absorbing equipment, in particular to a shock absorbing device for a mining vehicle-mounted camera. Background Art

[0002] Mining machinery such as mine trucks, loaders, excavators, etc. often have a large number of visual blind spots when operating in mines or open-pit mines. These blind spots are caused by the machine's own structure blocking the operator's line of sight, or by factors such as the terrain and obstacles at the work site. For example, during the loading and transportation of large mine trucks, it is difficult for the driver to directly observe the areas on both sides of the vehicle body, the rear of the vehicle, and near the wheels; when the loader is shoveling materials, there are blind spots behind its arm and bucket.

[0003] With the improvement of safety awareness and the development of monitoring technology, some mining machines have begun to try to install cameras to make up for the visual blind spots. However, new problems have arisen. Since the driving conditions of mining machinery are extremely harsh, there are strong vibration sources both underground and in open-pit mines. Underground mining operations, ore transportation and other activities constantly impact and vibrate the ground; open-pit mines generate continuous and large-scale vibrations due to high-speed driving of mine cars on uneven roads and blasting operations.

[0004] Most of the cameras installed on mining machinery lack special shock-absorbing devices, and the installation surfaces of the cameras on mining machinery are mostly non-planar. For some mine cars, the rear cameras are mostly installed on the inclined bottom surface of the car. Even if there are shock-absorbing devices, they cannot play a good shock-absorbing effect under the tilted condition. In a strong vibration environment, the optical components, image sensors and other precision components inside the camera will be seriously affected. The lens may shift and loosen due to vibration, resulting in blurry, deformed or even unfocused images. The image sensor will also collect unstable signals due to continuous vibration, causing noise, stripes and other interference in the captured video images, which seriously reduces the clarity and recognition of the image. This makes it difficult for operators to accurately obtain information about the working area through the camera, and it is impossible to effectively play the role of the camera in safety monitoring and production assistance, resulting in the installation of the camera failing to achieve the expected results, the safety hazards of mining machinery still exist, and it is difficult to substantially improve production efficiency.

[0018] See also Figures 1 to 8 The embodiment of the present application provides a shock absorbing device for a mining vehicle-mounted camera, including a base 1, a shock absorbing seat 2, a shock absorbing device 3, a universal joint bracket 7 and a connecting piece 8, and the base 1 and the shock absorbing seat 2 are connected through the shock absorbing device 3.

The lower end of the shock-absorbing device 3 is connected to the bottom of the groove 111, and the upper end of the shock-absorbing device 3 is connected to the inner wall of the top end of the shock-absorbing seat 2. The design of the groove 111 makes the overall structure of the upper base 11, the shock-absorbing device 3 and the shock-absorbing seat 2 more compact and reduces the occupied space.

The shock absorbing device 3 is connected to the bottom of the groove 111 and the inner wall of the top of the shock absorbing seat 2 through a countersunk screw. The wire rope shock absorber has good shock absorbing performance and has a good suppression effect on both high-frequency and low-frequency vibrations; the wire rope shock absorber has a high damping ratio, which can quickly convert mechanical energy into heat energy and dissipate it during vibration, greatly reducing the transmission and rebound of vibration, effectively reducing the vibration amplitude of the equipment, and improving the stability and reliability of the equipment; the wire rope shock absorber has excellent fatigue resistance. When subjected to pressure or tension, it can evenly distribute the load, give full play to the bearing capacity of the wire rope, and also improve the overall stability and bearing capacity of the shock absorbing device of the mining vehicle-mounted camera.

[0023] When the first bolt assembly is not fastened to the connector 8 and the lower base 13, the connector 8 can be rotated so that the connector 8 and the lower base 13 rotate relative to each other, thereby adjusting the installation angle of the connector 8. When the slopes of the horizontal plates 82 are consistent, it is convenient to install on the installation slope at the tail of the bottom of the mine car or the installation slope of other equipment; by adjusting the position of the first bolt in the long hole 811, and then adjusting the height of the horizontal plate 82, it can adapt to the installation slopes with different slopes. The lengths of the vertical plates 81 of the two connectors 8 of each group of connectors 8 can be set to be long and short, which is convenient for installation on the installation slope at the tail of the bottom of the mine car or the installation slope of other equipment. By adjusting the connector 8, it is convenient for the base and the shock-absorbing seat to be installed horizontally, so that the upper end surface of the shock-absorbing seat 2 can be roughly kept horizontal, that is, the shock-absorbing seat 2 can move relative to the upper base 11 in the vertical direction, which is convenient for the shock-absorbing device 3, the lower elastic shock-absorbing pad 12, the upper elastic shock-absorbing pad 4, the inner elastic shock-absorbing pad 5, and the outer elastic shock-absorbing pad 6 to fully exert the shock-absorbing function and achieve uniform shock absorption.
