Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, and particularly to a hydraulic cover opening device for a counterattack crusher. Background Technique

[0002] A counterattack crusher belongs to a machine device that uses impact energy to crush materials and is widely used in industrial sectors such as cement, building materials, coal, chemical industry, and mineral processing. In order to facilitate the maintenance of the crusher, hydraulic equipment is usually used to connect with the rear cover to conveniently open the rear cover for maintenance;

[0003] As shown in the reference case "A Hydraulic Maintenance Device for a Counterattack Crusher" with the publication number "CN212882723U", it can visually detect the inside of the crusher, improve the detection range, extend the service life of the equipment, improve the crushing efficiency, and reduce the production cost;

[0004] However, when opening the rear cover, the existing hydraulic cover opening device lacks a placement detection mechanism. This means that during maintenance, if the rear cover is not opened in place, it is very likely that maintenance personnel working inside the machine will be seriously injured. This problem not only increases the risk in the workplace but may also cause equipment damage, thus affecting production efficiency and safety.

[0005] Therefore, a hydraulic cover opening device for a counterattack crusher is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a hydraulic cover opening device for a counterattack crusher to solve the above problems, and improve the problem that when opening the rear cover, the existing hydraulic cover opening device lacks a placement detection mechanism. This means that during maintenance, if the rear cover is not opened in place, it is very likely that maintenance personnel working inside the machine will be seriously injured. This problem not only increases the risk in the workplace but may also cause equipment damage, thus affecting production efficiency and safety.

[0007] The present utility model realizes the above object through the following technical solutions. The hydraulic cover opening device of the impact crusher includes: a crusher, a feeding port is fixedly installed on one side of the crusher, a rear cover is arranged on one side of the feeding port, a fixed seat is fixedly installed on one side of the crusher, and a position detection mechanism for detecting the opening position of the rear cover is arranged on one side of the fixed seat. Among them, the position detection mechanism includes a detection frame fixedly installed on one side of the fixed seat, a detection component is arranged on one side of the detection frame, and a warning component is arranged on one side of the fixed seat. The opening position of the rear cover can be detected by the detection component to ensure that the rear cover is opened to a stable position, avoiding accidental closing of the rear cover due to not being opened to a stable position during maintenance, thereby improving the safety of maintenance. When the warning component detects that the rear cover is not fully opened or not stable, it will send a warning signal to prompt the operator and maintenance personnel to pay attention to safety and avoid accidents during maintenance work.

[0008] The detection component includes a placement groove opened on one side of the detection frame. A hydraulic rotary machine is fixedly installed on one side of the fixed seat, and the output end of the hydraulic rotary machine is fixedly connected to a driving frame. The driving frame is fixedly connected to the rear cover. A placement block is fixedly installed on one side of the driving frame. A fixed frame is fixedly installed inside the placement groove. A movable frame is slidably installed on one side of the fixed frame. One side of the movable frame extends into the placement groove. A plurality of pressure sensors are fixedly installed at the bottom of the movable frame. During use, the hydraulic rotary machine can rotate the driving frame, causing the driving frame to rotate the rear cover to open. When the driving frame rotates, the driving frame synchronously drives the placement block to move. When the placement block moves into the placement groove, at this time, the placement block contacts the movable frame, and by pushing the movable frame downward to contact the pressure sensors and reaching an appropriate pressure, it can be detected whether the position is fully opened.

[0009] The detection component further includes a plurality of springs fixedly installed at the bottom of the movable frame. The other ends of the plurality of springs are fixedly connected to the inner bottom wall of the fixed frame. When the movable frame moves downward, it can synchronously compress the plurality of springs, enabling the springs to provide necessary buffering and restoring forces when the movable frame moves downward, thereby avoiding too strong an impact between the movable frame and the pressure sensors and ensuring that the sensors can accurately measure without being interfered by sudden or excessive forces.

[0010] A contact wheel is rotatably installed on one side of the movable frame. The contact wheel is located inside the placement groove. When the placement block enters the placement groove, it can contact the contact wheel, and by squeezing the contact wheel, the movable frame moves downward, thereby reducing damage to the movable frame.

[0011] The placement block is triangular in shape, and the shape of the placement groove is adapted to the placement block. The triangular placement block and placement groove can ensure precise and stable guidance and positioning. The triangular design can improve the accuracy of the contact between the placement block and the placement groove. This shape helps with automatic centering and reduces installation errors.

[0012] The warning component includes a control seat fixedly installed on one side of the fixed seat. A buzzer is fixedly installed on one side of the control seat. When the placement block does not trigger the specified pressure, the control seat can control the buzzer to emit a warning prompt sound, enhancing the alertness of the surrounding maintenance personnel and ensuring that they are aware that the rear cover is in an unstable state.

[0013] A display screen is fixedly installed on the surface of the control seat, and multiple warning lights are fixedly installed on the surface of the control seat. The warning lights can be configured to display different colors to indicate different states or warning levels. For example, green indicates normal system operation, and red indicates an emergency or equipment failure, facilitating the observation of maintenance personnel in conjunction with the display screen.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The detection component can detect the opening position of the rear cover to ensure that the rear cover is opened to a stable position, preventing the rear cover from accidentally closing during maintenance when it is not opened to a stable position, thereby improving the safety of maintenance. When the warning component detects that the rear cover is not fully opened or is unstable, it will emit a warning signal to alert operators and maintenance personnel to pay attention to safety and avoid accidents during maintenance work;

[0016] 2. When the placement block does not trigger the specified pressure, the control seat can control the buzzer to emit a warning prompt sound, enhancing the alertness of the surrounding maintenance personnel and ensuring that they are aware that the rear cover is in an unstable state.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] During specific implementation: As Figures 1-5 shown, the hydraulic cover opening device of the impact crusher includes: a crusher 1, a feeding port 11 is fixedly installed on one side of the crusher 1, a rear cover 12 is arranged on one side of the feeding port 11, a fixed seat 2 is fixedly installed on one side of the crusher 1, and a position detection mechanism 3 for detecting the opening position of the rear cover 12 is arranged on one side of the fixed seat 2. Among them, the position detection mechanism 3 includes a detection frame 31 fixedly installed on one side of the fixed seat 2, a detection component 32 is arranged on one side of the detection frame 31, and a warning component 33 is arranged on one side of the fixed seat 2. The opening position of the rear cover 12 can be detected through the detection component 32 to ensure that the rear cover 12 is opened to a stable position, avoiding accidental closing of the rear cover 12 when it is not opened to a stable position during maintenance, thereby improving the safety of maintenance. When the warning component 33 detects that the rear cover 12 is not fully opened or not stable, it will emit a warning signal to prompt the operator and maintenance personnel to pay attention to safety and avoid accidents during maintenance work.

[0025] As Figure 2 、 Figure 3 and Figure 4As shown, the detection component 32 includes a placement groove 321 opened on one side of the detection frame 31. One side of the fixed seat 2 is fixedly installed with a hydraulic rotary machine 21, and the output end of the hydraulic rotary machine 21 is fixedly connected with a driving frame 22. The driving frame 22 is fixedly connected with the rear cover 12. One side of the driving frame 22 is fixedly installed with a placement block 322. The inside of the placement groove 321 is fixedly installed with a fixed frame 323. One side of the fixed frame 323 is slidably installed with a movable frame 324. One side of the movable frame 324 extends into the interior of the placement groove 321. The bottom of the movable frame 324 is fixedly installed with a plurality of pressure sensors 325. When in use, the hydraulic rotary machine 21 can rotate the driving frame 22, so that the driving frame 22 rotates to open the rear cover 12. When the driving frame 22 rotates, the driving frame 22 synchronously drives the placement block 322 to move. When the placement block 322 moves into the interior of the placement groove 321, at this time, the placement block 322 contacts the movable frame 324, and by pushing the movable frame 324 downward to contact the pressure sensors 325, when the appropriate pressure is reached, it can be detected whether the position is fully opened. The detection component 32 further includes a plurality of springs 326 fixedly installed at the bottom of the movable frame 324. The other ends of the plurality of springs 326 are fixedly connected with the inner bottom wall of the fixed frame 323. When the movable frame 324 moves downward, a plurality of springs 326 can be synchronously compressed, so that the springs 326 provide necessary buffering and restoring forces when the movable frame 324 moves downward, thereby avoiding too strong an impact between the movable frame 324 and the pressure sensors 325 and ensuring that the sensors can accurately measure without being disturbed by sudden or excessive forces. One side of the movable frame 324 is rotatably installed with a contact wheel 327. The contact wheel 327 is located inside the placement groove 321. When the placement block 322 enters the interior of the placement groove 321, it can contact the contact wheel 327, and by squeezing the contact wheel 327, the movable frame 324 moves downward, thereby reducing the damage to the movable frame 324. The placement block 322 is triangular in shape, and the shape of the placement groove 321 is adapted to the placement block 322. The accurate and stable guiding and positioning can be ensured through the triangular placement block 322 and the placement groove 321. The triangular design can improve the accuracy of the contact between the placement block 322 and the placement groove 321. This shape helps to automatically center and reduce the installation error.

[0026] As Figure 2 , Figure 3 and Figure 5As shown, the warning component 33 includes a control seat 331 fixedly installed on one side of the fixed seat 2. A buzzer 332 is fixedly installed on one side of the control seat 331. When the placement block 322 does not trigger the specified pressure, the control seat 331 can control the buzzer 332 to emit a warning sound, enhancing the alertness of the surrounding maintenance personnel and ensuring that they are aware that the rear cover 12 is in an unstable state. A display screen 334 is fixedly installed on the surface of the control seat 331, and a plurality of warning lights 333 are fixedly installed on the surface of the control seat 331. The warning lights 333 can be configured to display different colors to indicate different states or warning levels. For example, green indicates normal system operation, and red indicates an emergency or equipment failure, facilitating the observation of maintenance personnel in cooperation with the display screen 334.

[0027] When the present utility model is in use, the hydraulic rotary machine 21 can rotate to drive the driving frame 22, causing the driving frame 22 to rotate and open the rear cover 12. When the driving frame 22 rotates, the driving frame 22 synchronously drives the placement block 322 to move. When the placement block 322 moves into the placement groove 321, at this time, the placement block 322 contacts the movable frame 324, and by pushing the movable frame 324 downward to contact the pressure sensor 325, when the appropriate pressure is reached, it can be detected whether the position is fully opened. When the placement block 322 enters the placement groove 321, it can contact the contact wheel 327, and by squeezing the contact wheel 327, the movable frame 324 is moved downward, thereby reducing the damage to the movable frame 324. When the placement block 322 does not trigger the specified pressure, the control seat 331 can control the buzzer 332 to emit a warning sound, enhancing the alertness of the surrounding maintenance personnel and ensuring that they are aware that the rear cover 12 is in an unstable state. The warning lights 333 can be configured to display different colors to indicate different states or warning levels. For example, green indicates normal system operation, and red indicates an emergency or equipment failure, facilitating the observation of maintenance personnel in cooperation with the display screen 334.
