[0002] Since the material grabber is in the cabin during operation, it is often affected by factors such as the operator's line of sight or human error, and the material grabber often collides with the cabin, causing the drive motor or hydraulic motor of the material grabber to be damaged and unable to continue working. Existing anti-collision equipment is mainly used to prevent the material grabber from colliding with the pile of materials. It usually uses contact sensing to judge the distance, and if the material grabber collides, it will not cause obvious damage. However, if the drive motor collides with the cabin when used for grabbing materials in the cabin, it is easy to cause a lot of losses. Therefore, conventional contact alarm equipment cannot be used in anti-collision systems.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a cantilever anti-collision device for a stacker and reclaimer [201921026006.0], in which two supporting partitions are vertically welded on the plate surface of the bracket, the two ends of the telescopic sleeve are respectively fixedly connected to the circular holes of the supporting partitions, the two ends of the telescopic sleeve are respectively installed with sliding bushings, the rod body of the telescopic rod is located in the telescopic sleeve, the outer wall of the rod body of the telescopic rod and the inner wall of the sliding bushing of the telescopic sleeve are slidingly matched, the compression spring is located between the two sliding bushings in the inner hole of the telescopic sleeve, the compression spring is sleeved on the telescopic rod, the front end of the telescopic rod is connected to the baffle, the shield is sleeved on the outer side of the supporting partition and the telescopic sleeve, and the shield is connected to the bracket.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4As shown, an alarm detection device for automatic collision avoidance of a material grabber driven hydraulic motor comprises a hoop assembly 1 installed on the material grabber, the hoop assembly 1 is connected with an anti-collision assembly 2 surrounding the outer side of the hydraulic motor, the hoop assembly 1 can slide up and down to adjust the relative position with the material grabber, ensuring that the anti-collision assembly 2 fully protects the hydraulic motor, when the hydraulic motor of the material grabber collides with the cabin due to the influence of the operating line of sight or human operation errors, the first thing to be collided is the anti-collision assembly 2, and the hydraulic motor will not be directly collided. A sensor assembly 3 is installed on the anti-collision assembly 2 to detect the displacement change when a collision is about to occur or a collision occurs, and an alarm signal can be sent in time to remind the operator or the corresponding drive control structure can be used to operate the material grabber to move in the opposite direction to avoid a collision; the anti-collision assembly 2 is equipped with a joint expansion assembly 4 to realize the combined connection of multiple hoop assemblies 1 and their anti-collision assemblies 2, which can prevent the anti-collision assembly 2 from axially dislocating and offsetting relative to the hydraulic motor.

[0024] Specifically, the hoop assembly 1 includes symmetrically arranged and semi-cylindrical hoop pieces 11, the radius of which is adjusted according to actual needs to ensure full engagement with the feed barrel of the material extractor. Connecting ears 12 extending outward and having assembly holes are respectively provided at the ends of the hoop pieces 11, and reinforcing sheets 13 are respectively connected between the connecting ears 12 and the hoop pieces 11 above and below. The connecting ears 12 of the hoop pieces 11 overlap and are clamped together by screws 14 that penetrate the assembly holes. The relatively fitted connecting ears 12 are usually connected to two screws 14, which, when locked and fixed, apply a certain clamping force to the material extractor to prevent loosening and falling off.

[0025] In depth, the anti-collision assembly 2 adopts a cover structure for protection, specifically including an anti-collision cover 21 connected to one of the hoop pieces 11, the anti-collision cover 21 has a straight portion 22 connected to the hoop piece 11, a semi-cylindrical curved portion 23 is connected between the ends of the straight portion 22, and flanges 24 extending outward are respectively provided at the upper and lower ends of the straight portion 22. The curved portion 23 at the end of the anti-collision cover 21 is adapted to the outside of the hydraulic motor to ensure that the distance between the outside of the hydraulic motor and the inside of the anti-collision cover 21 is consistent, and the flange 24 can maintain the structural stability of the straight portion 22 in the event of a collision, so that the anti-collision cover 21 has a certain impact resistance.

[0026] Furthermore, since the height specifications of the hydraulic motors are inconsistent and other transmission structures need to be connected externally, the joint expansion component 4 further combines multiple anti-collision components 2, including an adapter sleeve 41, which is arranged between the upper and lower adjacent anti-collision components 2, and the adapter sleeve 41 has an adapter groove 42 for sliding and plugging the flange 24, and the adapter sleeve 41 has a limit plate 43 that fits the inner side of the straight portion 22. The adapter sleeve 41 connects the straight portions 22 to each other up and down, so that the central axes of the multiple anti-collision covers 21 coincide.

[0027] Furthermore, the adapter sleeve 41 includes an adapter plate 44 integrally formed with the limit plate 43, the adapter plate 44 is clamped and fixed between the upper and lower adjacent flanges 24, the adapter plate 44 and the limit plate 43 are T-shaped in cross section, a clamping plate 45 with a U-shaped cross section is slidably inserted at the top of the adapter plate 44, and the adapter groove 42 is located between the inner side of the clamping plate 45 and the outer side of the adapter plate 44; the clamping plate 45 and the adapter plate 44 are slidably inserted with each other through a sliding bar 46 and a sliding groove 47 with a dovetail cross section. The adapter plate 44 and the clamping plate 45 can be slidably inserted or separated. When assembling, the limit plate 43 and the adapter plate 44 are first clamped with the flange 24 and the straight portion 22, and then the clamping plate 45 is assembled to lock the flange 24.

[0028] At the same time, a gasket 5 made of flexible material is clamped and fixed between the inner side of the hoop assembly 1 and the material picker to prevent the hoop assembly 1 from directly contacting the material picker. The gasket 5 is usually made of rubber material to provide greater contact friction, which can reduce vibration and noise when the material picker vibrates.

[0029] It can be seen that the inner side of the anti-collision component 2 is isolated from the hydraulic motor, and the anti-collision component 2 can provide a sufficient buffer distance when a contact collision occurs.

[0030] Obviously, the sensing assembly 3 includes a distance sensor 6 installed outside the anti-collision assembly 2, and the distance sensor 6 is connected to the alarm module 62 via a wireless transmission module 61. The distance sensor 6 monitors the relative distance to the cabin in real time, and its alarm module 62 can use sound and light alarms to remind the operator to adjust the operation mode in time.

[0031] Preferably, the distance sensor 6 adopts any one or more combinations of infrared sensors, laser sensors, and ultrasonic sensors. For cost considerations, the present application prefers infrared sensors. Multiple infrared sensors are arranged along the outer side of the anti-collision cover 21 to ensure the warning coverage range.

[0032] In summary, the principle of this embodiment is that the hoop assembly 1 is fixed to the material picker, and the anti-collision assembly 2 connected thereto protects the outside of the hydraulic motor. When the material picker approaches the cabin, the sensor assembly 3 monitors the relative distance therebetween, and sends an alarm signal if there is a risk of collision.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
