Description

Technical Field

[0001] The invention relates to the technical field of industrial production equipment, and in particular to a safety protection device for improving production safety. Background Art

[0002] Work safety is the foundation of production activities of enterprises and institutions. It is related to the success or failure of production and operation activities and the physical and mental health and even life safety of employees. It is one of the important contents of modern production activities. In some production scenarios involving material allocation and use, the aforementioned work safety issues are usually involved, such as in the unloading conveyor scenario; For example, the patent with publication number CN115402809B discloses a conveyor for coal unloading, including a conveying mechanism, a screening mechanism is fixedly provided at the bottom of the conveying mechanism, and the screening mechanism is arranged in two groups; a guide rail is movably provided at the bottom of the conveying mechanism, and the guide rail is arranged in several groups; a pulling mechanism is movably provided on one side of the conveying mechanism, and a dumping mechanism is rotatably connected on the other side of the conveying mechanism; the conveying mechanism includes a driving box and a conveying box, and the driving box is connected to one end of the conveying box; the screening mechanism includes a fixed seat and a movable seat, a slide groove is provided on the top of the fixed seat, a discharge port is provided in the middle of the fixed seat, a sub-screening plate is fixedly connected to one end of the movable seat, a switching cylinder is fixedly connected to the other end of the movable seat, and positioning blocks are fixedly provided on both sides of the movable seat. The coal unloading conveyor of the present invention can screen the coal according to its size, making subsequent processing and retrieval more convenient; however, the unloading box of this application is not equipped with a safety protection device during the overturning process, and is prone to overturning when its load-bearing capacity is exceeded, posing a greater safety hazard to construction personnel. At the same time, the overturned coal blocks directly overturn on the conveying mechanism, causing an impact on the structure of the conveying mechanism, thereby reducing the service life of the conveying mechanism.

[0003] The existing patent with publication number CN112455310A discloses a dumping conveyor and dumping method for a semi-trailer, wherein the dumping conveyor for the semi-trailer includes a conveyor belt installed on the lower inner side of the carriage, the rotating wheel on the conveyor belt is connected to an output end of a rotating drive device, and the other output end of the rotating drive device is fixedly connected to a threaded rod; since the scraping mechanism and the like are arranged on one side of the inner wall of the carriage, the present invention does not need the bottom plate of the carriage as a mounting portion, so that the present invention can be well applied to conveyor belt type dump semi-trailers, and it is also necessary to use a flushing method to clean up debris, which further saves water resources; however, the safety protection measures of the application are not perfect. For example, when the conveying mechanism slips, the temperature of the conveying mechanism gradually increases under the action of friction, which can easily cause the equipment to catch fire, and even ignite the coal, causing a production safety accident. Therefore, it is necessary to optimize the structure of the conveying mechanism to prevent the coal from being ignited or spontaneously combusting. Summary of the invention

A plurality of inlet and outlet valves 322 passing through the upper and lower parts are provided in the wear-resistant layer 309, and a plurality of capillaries 321 passing through the upper and lower parts are also provided. The outer conveyor belt assembly 3 also includes an active roller 325, and also includes an active roller shaft 327 coaxial with the active roller 325. The active roller shaft 327 is hollow inside. One end of 327 is connected to an active roller liquid inlet pipe 326 through a rotary joint, and a driven wheel 330 is provided at the other end of the active roller shaft 327. It also includes a roller drive motor 328. A driving wheel is provided at the output end of the roller drive motor 328, and also includes a roller transmission belt 329 connecting the driving wheel and the driven wheel 330.

[0033] In this embodiment, the roller drive motor 328 drives the driving wheel to rotate, and then drives the driven wheel 330 to rotate through the roller transmission belt 329, and then drives the driving roller 325 to rotate. Since the conveyor belt 308 goes around the conveyor belt bracket 301 and is close to the outer side of the driving roller 325, the driving roller 325 drives the conveyor belt 308 to move through friction when it rotates; In particular, since active roller paddles 331 and active roller nozzle paddles 332 are arranged at intervals along the length direction on the outer wall surface of the active roller 325, and paddle grooves 323 and nozzle grooves 324 are opened at the bottom end of the wear-resistant layer 309 of the conveyor belt 308, the active roller paddles 331 are engaged with the paddle grooves 323, and the active roller paddles 331 are made of elastic material, allowing a certain deformation to compensate for the alignment deviation, and the active roller nozzle paddles 332 are engaged with the nozzle grooves 324. When the active roller 325 rotates, the active roller paddles 331 and the active roller nozzle paddles 332 drive the conveyor belt 308 to rotate with the active roller 325. At the same time, the swivel joint is used to The active roller liquid inlet pipe 326 is connected to the active roller shaft 327. The active roller 325 is hollow. A plurality of nozzles 333 are arranged on the outside of the active roller 325. The nozzles 333 are all connected to the inside of the active roller 325 and penetrate the active roller nozzle paddle 332. Since a water delivery chamber 310 is arranged in the conveyor belt 308, an inlet and outlet valve 322 connecting the inside and outside of the water delivery chamber 310 is arranged in the wear-resistant layer 309. The inlet and outlet valve 322 and the nozzle 333 are matched in male and female. Therefore, when the active roller nozzle paddle 332 is engaged with the nozzle groove 324, the inlet and outlet valve 322 and the nozzle 333 are matched in male and female, so that external water enters the water delivery chamber 310 through the active roller liquid inlet pipe 326. Then, since the cooling nozzle 312 is provided in the conveyor belt 308, when the conveyor belt 308 is working, the crushed coal is dumped onto the conveyor belt 308 through the dumping device 2, and then water is sent into the water delivery chamber 310 through the active roller liquid inlet pipe 326, and then the water in the water delivery chamber 310 is sprayed on the coal transported on the conveyor belt 308 through the cooling nozzle 312, so as to reduce dust on the coal and cool and moisten the coal, thereby reducing the risk of spontaneous combustion caused by the increase of internal temperature of the coal during the stacking process; Since the outer side surfaces of the right driven roller 304 and the left driven roller 307 of the conveyor belt bracket 301 are provided with a plurality of paddles, the paddles are engaged with the paddle grooves 323, thereby preventing the right driven roller 304 and the left driven roller 307 from slipping with the conveyor belt 308. Finally, the capillaries 321 on the wear-resistant layer 309 penetrate liquid toward the bottom of the wear-resistant layer 309, and the wear-resistant layer 309 and the right driven roller 304, the left driven roller 307 and the horizontal driven roller 306 are connected. The contact surface is cooled to reduce the temperature of the conveyor belt 308 and prevent the conveyor belt 308 from self-igniting. The main structure of the inner conveyor belt assembly 7 is the same as that of the outer conveyor belt assembly 3. An electromagnetic track device (disclosed in the application with publication number CN207573213U) is provided at the contact surface end between the bottom end of the inner conveyor belt assembly 7 and the inner bottom end of the outer conveyor belt assembly 3 to facilitate the sliding of the inner conveyor belt assembly 7 in the outer conveyor belt assembly 3, thereby realizing the adjustment of the unloading distance.
