Description

Technical Field

[0001] This utility model relates to the technical field of production equipment in the cleaning workshop, specifically to an anti-collision safety linkage device. Background Technology

[0002] The high degree of automation and pipeline construction in the Tsinghua workshop means that the workshop is basically unattended. Long-term production can lead to the accumulation of fly shavings on the track of the disc cotton grabber, which may cause the rollers to jam, overheat, and catch fire. Also, the disc runs at a high speed, and when people get close, they may collide and cause production accidents.

[0003] A search revealed that the prior art publication number CN216809040U discloses a disc cotton grabber, including a cylindrical cotton storage bin. A fixed platform is set at the center of the cotton storage bin, and a drive motor is set at the bottom of the fixed platform. An installation platform is set on the fixed platform, and a first guide component is set on the side of the installation platform away from the fixed platform. A cotton suction mechanism is set on the installation platform, and a pre-opening mechanism for opening cotton bales in the cotton storage bin is also set on the fixed platform. The pre-opening mechanism can preliminarily open the cotton bales in the cotton storage bin, thereby ensuring the degree of opening of the cotton bundles and thus ensuring the quality of the subsequent finished products.

[0004] However, existing technologies lack anti-collision and cleaning effects. During production, fly waste inevitably occurs in the cleaning workshop. The rolling rollers and blades collect and entangle the fly waste, causing the rollers to jam. In extreme cases, the jammed rollers generate heat through friction, creating a fire source. Furthermore, since the workshop is unattended and the equipment is open, if personnel accidentally approach the equipment, they are easily injured due to the lack of an automatic stop device.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, a collision avoidance safety linkage device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anti-collision safety linkage device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A collision avoidance safety linkage device includes: a cotton storage bin, an annular track is provided on the outer side of the cotton storage bin, a cotton grabber body is slidably installed on the annular track, and a controller is fixedly installed on the side wall of the cotton grabber body; and an anti-collision mechanism is provided on the front side of the cotton grabber body.

[0009] Preferably, the anti-collision mechanism includes: a baffle, the baffle being disposed on the front side of the telescopic spring rod, and a brush being fixedly installed on the bottom surface of the baffle, the brush being in contact with the annular track.

[0010] Preferably, the anti-collision mechanism further includes: a telescopic spring rod, which is disposed between the baffle and the cotton grabber body. A first stop rod is hinged to the side wall of the baffle, and a second stop rod is hinged to the side wall of the first stop rod. The other side of the second stop rod is hinged to the front side wall of the cotton grabber body.

[0011] Preferably, the anti-collision mechanism further includes a trigger sensor, which is fixedly installed on the bottom surface of the second stop bar. When the first stop bar and the second stop bar are folded, the bottom surface of the trigger sensor contacts the top surface of the telescopic spring bar.

[0012] Preferably, the width of the brush exceeds that of the annular track and is located at the center of the annular track.

[0013] Preferably, the controller includes a signal processing module and a control module. The signal processing module is used to receive and process signals sent by the trigger sensor, and the control module is used to control the operating state of the cotton grabber body according to the processed signals, including stopping, decelerating, or changing direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by incorporating an anti-collision mechanism, when personnel or obstacles accidentally approach, the controller is triggered within seconds to stop the cotton grabber body from operating through the coordinated action of a telescopic spring rod, a first stop rod, a second stop rod, and a trigger sensor. This rapid response mechanism effectively avoids collision accidents, providing a solid safety guarantee for workshop workers, and is especially suitable for unattended cotton cleaning workshops, greatly reducing the risk of production safety accidents.

[0016] 2. In this utility model, by incorporating a brush that continuously cleans the annular track during the operation of the cotton grabber, with the brush's width exceeding 30% of the track and centered, thorough and comprehensive cleaning is ensured. Timely removal of fly ash effectively prevents the roller blades from jamming due to fly ash entanglement, thereby avoiding the risk of frictional heating and fire caused by jamming. This significantly extends the equipment's service life, improves the stability and reliability of equipment operation, and reduces equipment maintenance costs and downtime.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In one typical embodiment of this application, please refer to Figures 1-2 As shown, an anti-collision safety linkage device includes: a cotton storage bin 1, an annular track 2 is provided on the outside of the cotton storage bin 1, a cotton grabber body 3 is slidably installed on the annular track 2, and a controller 4 is fixedly installed on the side wall of the cotton grabber body 3.

[0022] The anti-collision mechanism is located on the front side of the cotton grabber body 3.

[0023] The anti-collision mechanism includes: a baffle 5, which is set on the front side of the telescopic spring rod 7. A brush 6 is fixedly installed on the bottom surface of the baffle 5. The diameter of the brush 6 is not less than 1mm. The distance between the brush 6 and the annular track 2 is -1mm. The width of the brush 6 needs to exceed 30% of the annular track 2 and needs to be centered. The brush 6 is in contact with the annular track 2.

[0024] The anti-collision mechanism also includes: a telescopic spring rod 7, which is set between the baffle 5 and the cotton grabber body 3. The spring force of the telescopic spring rod 7 is controlled between 50 and 200 N. A first stop rod 8 is hinged to the side wall of the baffle 5, and a second stop rod 9 is hinged to the side wall of the first stop rod 8. The other side of the second stop rod 9 is hinged to the front side wall of the cotton grabber body 3.

[0025] The anti-collision mechanism also includes a trigger sensor 10, which is fixedly installed on the bottom surface of the second stop 9. When the first stop 8 and the second stop 9 are folded, the bottom surface of the trigger sensor 10 contacts the top surface of the telescopic spring rod 7.

[0026] Through the above features, the surface of the circular track 2 can be cleaned, and personnel can be prevented from accidentally approaching the equipment due to the lack of an automatic stop device, which could cause injury. Specifically, when the cotton grabber body 3 starts, it will move on the circular track 2, causing the baffle 5 to move synchronously. When the baffle 5 moves, the brush 6 will clean the circular track 2 to prevent the roller wings at the bottom of the cotton grabber body 3 from accumulating and getting tangled with flying cotton, which could cause the rollers to jam. In extreme cases, the jamming can cause friction and heat, forming a fire source. In addition, when the baffle 5 and the brush 6 collide with personnel, the telescopic spring rod 7 will retract, causing the first stop rod 8 and the second stop rod 9 to fold, so that the trigger sensor 10 contacts the top surface of the telescopic spring rod 7, causing the trigger sensor 10 to send an electrical signal to the controller 4, which will stop the cotton grabber body 3.

[0027] It is worth mentioning that the response time of the equipment needs to be tested during installation, and the time from touching the equipment to stopping should not exceed one second.

[0028] The width of the brush 6 exceeds that of the annular track 2 and is located at the center of the annular track 2.

[0029] The controller 4 is equipped with a signal processing module and a control module. The signal processing module is used to receive and process the signals sent by the trigger sensor 10, and the control module is used to control the operating status of the cotton grabber body 3 according to the processed signals, including stopping, decelerating or changing direction.

[0030] Working principle:

[0031] In operation, when the cotton grabber body 3 starts, it moves along a set path on the circular track 2, simultaneously moving the baffle 5 synchronously. During this process, the brush 6 closely contacts the circular track 2, and with its width exceeding 30% of the circular track 2 and centered design, it cleans the track in real time, effectively preventing the accumulation and entanglement of fly ash on the roller wings at the bottom of the cotton grabber body 3. If a person accidentally approaches the equipment, the baffle 5 and brush 6 will first come into contact with the person. At this time, the telescopic spring rod 7 quickly retracts, causing the first baffle 8 and the second baffle 9 to fold. The trigger sensor 10 then contacts the top surface of the telescopic spring rod 7 and sends an electrical signal to the controller 4 in a very short time (no more than 1 second). Upon receiving the signal, the controller 4 immediately controls the cotton grabber body 3 to stop operating, eliminating the risk of injury to personnel due to collision at the source. Throughout the process, all components work together to ensure both the cleanliness of the track and efficient protection of personnel safety. The spring force of the telescopic spring rod 7 is precisely controlled within the range of 50 to 200N to ensure a sensitive response in the event of a collision, providing reliable dual protection for equipment and personnel.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
