[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0030] Example 1
[0031] Reference Figures 1-3 This embodiment provides a mechanism for preventing the dump truck bed from being left unloaded in a mining heavy-duty dump truck, including: an alarm unit 100, which includes a truck bed frame 101 and a truck bed 102 hinged to the top of the truck bed frame 101. A limit groove 103 is formed on the upper surface of the truck bed frame 101, and two buzzers 106 are fixedly installed on the top of the truck bed frame 101. The two buzzers 106 are symmetrical about the limit groove 103. Each buzzer 106 has a tactile switch 107 on its top for starting and stopping the alarm. The interior of the trough 103 is equipped with a triggering component; a discharge plate adjustment unit 200 is provided between the rear of the truck bed 102 and the truck bed frame 101, and the interior of the truck bed 102 is also equipped with a discharge unit 300 for quickly unloading the ore. The side of the truck bed 102 near the truck cab is equipped with a drive unit 400 for driving the discharge unit 300. When the truck bed 102 moves upward, it will not press the tactile switch 107. At this time, the tactile switch 107 can activate the buzzer 106 to sound an alarm and remind the driver that the truck cab is in the raised state.
[0032] Furthermore, the triggering component includes a sliding column 104 that is axially slidably disposed inside the limiting straight groove 103, and a spring 105 is provided at one end of the sliding column 104 that extends into the limiting straight groove 103. A protective plate 108 is fixedly installed at one end of the sliding column 104 near the truck bed 102, and the protective plate 108 is located directly above the two buzzers 106.
[0033] The working principle of the system that effectively reminds the driver that the truck bed 102 is in the raised state is as follows: When the driver raises the truck bed 102 for unloading, the pressure on the protective plate 108 is released the instant the truck bed 102 is raised. During the upward movement of the protective plate 108, the tactile switch 107 is no longer pressed. The tactile switch 107 is a reverse switch, meaning that when it is not pressed, the buzzer 106 is in the activated state, and when it is pressed, the buzzer 106 is in the deactivated state. After the protective plate 108 moves upward, the buzzer 106 will emit a loud alarm sound to inform the driver that the truck bed 102 has been raised. If the driver does not actively lower the truck bed 102 after unloading, the buzzer 106 will continue to emit an alarm sound to inform the driver that the truck bed 102 has not been reset. This can prevent the driver from forgetting to lower the truck bed 102, which could lead to driving with the truck bed 102 raised and causing damage to the high-voltage lines in the mine.
[0034] The protective plate 108 is located directly above the buzzer 106 and has a certain protective function. It can prevent small ore particles from accidentally touching the touch switch 107 or blocking the buzzer 106's generating hole during unloading.
[0035] Example 2
[0036] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:
[0037] In this design, the unloading plate adjustment unit 200 includes a baffle 201 hinged to the lower end of the rear of the truck bed 102. Two arc-shaped sealing cylinders 202 are fixedly installed at the bottom of the truck bed 102. An arc-shaped sliding rod 203 is slidably embedded in the interior of each arc-shaped sealing cylinder 202 at the end furthest from the truck bed 102. The exposed ends of the two arc-shaped sliding rods 203 are fixedly connected to the baffle 201. An arc-shaped piston rod is fixedly installed at the end of each arc-shaped sliding rod 203 furthest from the baffle 201, and the outer diameter of the arc-shaped piston rod is larger than that of the arc-shaped sliding rod 203. The outer diameter of 03 is such that a connecting pipe 1 212 and a connecting pipe 213 are fixedly connected between the two arc-shaped sealing cylinders 202. The arc-shaped piston column is located between the connecting pipe 1 212 and the connecting pipe 213, and the connecting pipe 1 212 is located on the side of the arc-shaped sealing cylinder 202 away from the truck bed 102. The inside of the truck bed frame 101 is provided with a supply component for filling the inside of the two arc-shaped sealing cylinders 202. The swing trajectory of the baffle 201 is exactly the trajectory of the arc-shaped slide rod 203 sliding inside the arc-shaped sealing cylinder 202.
[0038] Furthermore, the supply component includes a pressure cylinder 204 fixedly installed inside the vehicle frame 101, and a piston disc 205 is slidably embedded inside the pressure cylinder 204. A light shaft 206, which slides through the pressure cylinder 204, is fixedly installed at one end of the piston disc 205 near the vehicle bed 102. A first delivery pipe 208 and a second delivery pipe 209 are fixedly connected to the outer wall of the pressure cylinder 204, with the first delivery pipe 208 located below the second delivery pipe 209 and away from the pressure cylinder 204. One end of the conveying pipe 209 is fixedly connected to the connecting pipe 213 by a hose 210, and the end of the conveying pipe 209 away from the pressure cylinder 204 is fixedly connected to the connecting pipe 212 by a hose 211. A connecting component 207 is provided between the optical shaft 206 and the bucket 102. That is, when the bucket 102 moves up and down, the piston disc 205 moves up and down, and the liquid or gas inside the arc-shaped sealing cylinder 202 can flow in an orderly manner through the cooperation of the four conveying pipes, and touch the baffle 201.
[0039] Furthermore, the connecting component 207 includes a limiting post 207a fixedly installed on the top of the optical axis 206, and two symmetrically distributed C-shaped groove plates 207b fixedly installed at the bottom of the bucket 102. Both ends of the limiting post 207a are slidably embedded in the interior of the C-shaped groove plate 207b. That is, during the lifting and moving process, the bucket 102 can press or lift the optical axis 206 through the sliding engagement of the C-shaped groove plate 207b and the limiting post 207a.
[0040] In this embodiment: Considering that the rear of the existing mining truck bed 102 is a fixed horizontal plate structure, during the unloading process of the bed 102, some ore may not be completely unloaded and may remain inside the bed 102. Therefore, in this solution, when the bed 102 is raised, the optical shaft 206 can be lifted upwards through the sliding engagement of the C-shaped groove plate 207b and the limiting post 207a. During the lifting process, the pressure liquid or air on the upper part of the piston disc 205 will enter the bottom of the arc-shaped sealing cylinder 202 through the second conveying pipe 209, the second hose 211, and the first connecting pipe 212, pushing the arc-shaped piston column upwards, that is, allowing the arc-shaped sliding rod 203 to extend into the interior of the arc-shaped sealing cylinder 202. At this time, the baffle 201 can open automatically and will not obstruct the unloading of the ore.
[0041] After the unloading of the hopper 102 is completed, when it is reset, the piston disc 205 moves downward, and its pressurized liquid or air will be transported in the opposite direction. The arc-shaped piston rod pushes the arc-shaped slide rod 203 toward the outside of the arc-shaped sealing cylinder 202. At this time, the baffle 201 will also close automatically.
[0042] The automatic opening or closing of the baffle 201, which is linked to the raising or lowering of the truck bed 102, can also prevent the situation from being forgotten to close the baffle 201.
[0043] Example 3
[0044] Reference Figures 6-9 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that: the unloading unit 300 includes a plurality of linearly equidistant grooves 301 formed on the upper end face of the truck bed 102, and a mating strip 302 is slidably embedded inside each groove 301. A limiting cavity 303 is formed inside the truck bed 102 on the side near the truck head, and the limiting cavity 303 is interconnected with the grooves 301. The end of the mating strip 302 near the truck head is slidably embedded in the limiting cavity 303. The limiting cavity 303 has a slidingly embedded touch plate 304, which is located on the upper end face of the mating strip 302. Each mating strip 302 has a fixedly installed positioning post 306 at one end near the limiting cavity 303. The touch plate 304 has several inclined grooves 305 that are equidistantly distributed in a straight line. The positioning post 306 is slidably embedded in the inclined grooves 305. During the sliding process, the touch plate 304 can make several mating strips 302 slide by engaging the inclined grooves 305 and the positioning post 306.
[0045] Furthermore, the end face of the mating strip 302 away from the limiting cavity 303 does not extend beyond the rear end face of the truck bed 102. In order to ensure that the mating strip 302 will not affect the closing of the baffle 201 when it stops moving, the mating strip 302 will not extend to the rear end face of the truck bed 102.
[0046] Furthermore, the drive unit 400 includes a motor 401 fixedly installed on the side of the truck bed 102, a connecting plate 403 fixedly installed on one end of the touch plate 304, and a cam 402 fixedly installed on the output end of the motor 401. The cam 402 is located below the touch plate 304, and a perimeter groove 404 is provided around the cam 402. A limiting ball block 405 that slides and engages with the perimeter groove 404 is fixedly installed on the end of the connecting plate 403 near the cam 402. When the motor 401 drives the cam 402 to rotate, the connecting plate 403 can move back and forth through the engagement of the limiting ball block 405 with the perimeter groove 404.
[0047] Furthermore, the truck bed 102 is provided with a hammering component on the end face near the truck head. The hammering component includes a toothed plate 307 that is slidably embedded inside the truck bed 102 and is fixed to the upper part of the actuating plate 304. A gear 308 that meshes with the toothed plate 307 is also rotatably embedded inside the truck bed 102. A frame plate is fixedly installed on the end of the truck bed 102 near the truck head, and a column 309 is rotatably installed inside the frame plate. The outer wall of the column 309 has several toothed grooves 310 that mesh with the gear 308. A crossbar 311 is fixedly installed on the top of the column 309, and a ball hammer 312 is fixedly installed on the end of the crossbar 311 away from the column 309. When the actuating plate 304 slides with the toothed plate 307, it can also make the column 309 rotate. When it rotates back and forth, the ball hammer 312 can strike the truck bed 102 and generate vibration.
[0048] In this embodiment: the mine often experiences rainy weather when transporting ore. Under such circumstances, the ore is damp, and during the unloading process, many small-volume ore particles will adhere to the surface of the truck bed 102 and cannot be completely unloaded. In this solution, when the truck bed 102 is raised for unloading, the motor 401 can be started. Through the drive of the cam 402 by the motor 401, the touch plate 304 can be moved back and forth. During the movement, through the active engagement of the inclined groove 305 and the positioning column 306, several mating strips 302 can be moved back and forth quickly in the sliding groove 301. During the sliding process, the downward speed of the ore can be accelerated.
[0049] Meanwhile, as the actuating plate 304 moves back and forth with the toothed plate 307, the column 309 can swing back and forth with the crossbar 311 through the action of the gear 308 and the tooth groove 310. During the swing, the ball hammer 312 can strike the outer wall of the truck bed 102. The vibration generated by the striking can accelerate the removal of the ore adhering to the inside of the truck bed 102. With the sliding cooperation of the mating bar 302, the wet ore can be effectively unloaded.
[0050] Example 4
[0051] Reference Figure 10 This is the third embodiment of the present invention, which is a further description of another implementation of the third embodiment. The crossbar 311 includes a first rod portion 311a and a second rod portion 311b. The first rod portion 311a and the second rod portion 311b are fixedly connected to the ball hammer 312 and the column 309, respectively. The ends of the first rod portion 311a and the second rod portion 311b that are close to each other are movably hinged. A clamping plate 311c is fixedly installed on the end face of the first rod portion 311a that is close to the truck bed 102. A second spring 311d is provided on the end face of the first rod portion 311a and the second rod portion 311b that is away from the clamping plate 311c. The two ends of the second spring 311d are fixedly connected to the first rod portion 311a and the second rod portion 311b.
[0052] In this embodiment, the segmented design of the first rod 311a and the second rod 311b, during the swinging process, if the angle of the reciprocating rotation of the column 309 is greater than 90 degrees, the swinging of the column 309 will cause the first rod 311a and the second rod 311b to bend when the ball hammer 312 strikes the truck bed 102. The second spring 311d will also be compressed, and the reaction force generated by the strike will also be applied to the ball hammer 312, causing the ball hammer 312 to rebound slightly. Combined with the elasticity applied by the second spring 311d, after the ball hammer 312 strikes the truck bed 102 once, due to the rebound effect, there will be multiple high-frequency, small-amplitude strikes on the truck bed 102. Combined with the reciprocating rotation of the column 309, the vibration effect generated by the ball hammer 312 striking the truck bed 102 can be further improved.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
