Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and in particular to a non-traction metallurgical vehicle with multiple control modes. Background Technology

[0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with certain properties using various processing methods. Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of iron and steel smelting in modern times. In the metallurgical process, it is often necessary to recycle and reuse scrap metal blocks. When recycling scrap metal blocks, they need to be crushed again to achieve metal reuse. After the scrap metal blocks are crushed by the crusher, a trolley is usually placed at the lower end of the crusher's outlet to facilitate the collection and transfer of the crushed metal.

[0003] For example, Chinese Patent Publication No. CN218258285U discloses a metallurgical solid waste transport trolley. This trolley includes a vehicle body with casters at the bottom and handrails welded to the side walls. An unloading mechanism is installed inside the vehicle body, comprising a baffle and a ratchet. The top of the baffle is hinged to the inner wall of the vehicle body, and a stop block is welded to the inner wall of the baffle. By setting up this unloading mechanism, during unloading, the device releases the ratchet's limiting position, allowing the baffle to open and dump the waste inside. After dumping, a crank handle rotates the ratchet, causing it to reel in a cable, thus resetting the baffle. The ratchet's one-way limiting position further restricts the baffle's movement. Throughout the process, workers do not need to manually contact the vehicle body or the baffle, thus better protecting their safety.

[0004] The above application still has shortcomings. When the device in the above application is in use, due to the height difference between the trolley and the discharge port of the crusher, some coarse or incompletely crushed metal blocks will fall into the hopper. Under the reaction force, the hopper will vibrate continuously, causing the wheels to vibrate significantly, which will easily damage the wheels and affect their service life. At the same time, the contact area between the wheels and the ground is small, and the hopper is not placed stably when holding materials. The continuous vibration can easily cause the hopper to deviate from the discharge port. When loading materials, a large amount of dust will often be raised, polluting the surrounding air environment and easily causing certain harm to the workers.

[0005] Therefore, it is necessary to provide a non-traction metallurgical vehicle with multiple control modes to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a non-traction metallurgical vehicle with multiple control modes to solve the problems in the prior art where coarse or incompletely crushed metal blocks impact and fall into the truck bed, causing the wheels to vibrate significantly and thus easily damage them; the truck bed is not stable enough when holding materials, and continuous vibration can easily cause the truck bed to deviate from the discharge port; and a large amount of dust is often raised when loading materials, polluting the surrounding air environment.

[0007] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a non-traction metallurgical vehicle with multiple control modes, comprising a support plate and a truck bed fixed to the top of the support plate, a base plate being provided directly below the support plate, a plurality of sliding lower connecting rods being fixed to the bottom of the support plate, wheels being provided at the bottom ends of the lower connecting rods, outrigger seats being fixed to the bottom of the base plate, and a pushing assembly being provided at the bottom of the truck bed, which drives the outrigger seats to contact the ground for stable support by the gravity of the material, and a decompression assembly being connected to the pushing assembly.

[0008] As a further embodiment of the present invention, the pushing assembly includes a groove formed in the bottom of the truck bed, a sliding and lifting bottom pressure plate disposed in the groove, a first connecting post fixed to the bottom of the bottom pressure plate that slides through the bottom of the truck bed and the support plate, an outer sleeve sleeved outside the first connecting post fixed to the bottom of the support plate, a first piston plate tightly fitted to the inner wall of the outer sleeve fixed to the bottom end of the first connecting post, a second connecting post inserted into the outer sleeve fixed to the top end of the bottom plate, and a second piston plate tightly fitted to the inner wall of the outer sleeve fixed to the top end of the second connecting post.

[0009] As a further embodiment of the present invention, a reset spring is provided between the bottom side of the bottom pressure plate and the bottom side of the groove.

[0010] As a further embodiment of the present invention, a plurality of reset springs are provided, and the plurality of reset springs are distributed at equal intervals.

[0011] As a further embodiment of the present invention, the decompression assembly includes a fluid passage tube communicating with the inside of the outer sleeve, and a connector tube communicating with the end of the fluid passage tube away from the outer sleeve. An outer sleeve is threadedly connected to the outer side wall of the connector tube, and a connecting rod inserted into the connector tube is fixed at the center of the top of the outer sleeve. A piston plate No. 3 is fixed at the bottom of the connecting rod and fits tightly against the inner side wall of the connector tube.

[0012] As a further embodiment of the present invention, a handle is fixed to the top of the outer sleeve, and a rubber sleeve is fitted onto the surface of the handle.

[0013] As a further embodiment of the present invention, a fixing plate is fixed on the side of the base plate, and the liquid passage pipe passes through the top side of the fixing plate and is fixed to the fixing plate.

[0014] As a further embodiment of the present invention, a purification component for removing dust is provided on the top of the truck bed. The purification component includes a concave seat fixed to the side of the top of the truck bed, a dust suction chamber is provided in the concave seat, and a dust suction hole communicating with the dust suction chamber is provided on the side of the concave seat near the opening at the top of the truck bed. Multiple dust suction holes are provided and are equidistantly distributed. A connecting pipe communicating with the dust suction chamber is fixed to the outer surface of the concave seat. A vacuum cleaner is fixed to the top side of the support plate, and the output end of the vacuum cleaner is connected to the end of the connecting pipe away from the concave seat.

[0015] As a further embodiment of the present invention, two lower connecting rods on the same side along the length of the truck bed are rotatably connected to a wheel axle. The wheel is installed at both ends of the wheel axle. A toothed ring is fixed on the side of one of the wheel axles. A motor is provided on one side of the wheel axle. A gear that meshes with the toothed ring is fixed on the output end of the motor.

[0016] As a further embodiment of the present invention, two symmetrically distributed diagonal rods are fixed to one end of the support plate, and push handles are fixed to the top ends of the two diagonal rods.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When receiving materials, after the materials are put into the truck bed, the gravity of the materials drives the pushing component to work. The pushing component pushes the bottom plate downward, causing multiple wheels to move upward and suspend in the air. This allows the multiple support legs at the bottom of the bottom plate to stably support the ground, thereby effectively improving the stability of the truck bed when receiving materials. This avoids the problem of the wheels being easily damaged due to violent vibration caused by the impact of metal blocks when the truck bed is receiving materials. It also effectively reduces subsequent wheel maintenance and extends the overall service life of the truck body.

[0019] 2. After the material is loaded, the decompression component releases the pressure of the material's gravity on the support legs, allowing the weight of the material in the bucket and the bucket's own weight to push multiple wheels down to contact the ground. This switches to multiple wheels for landing, and the entire device can then be easily moved using the multiple wheels. The push and decompression components work together to achieve convenient switching between fixed placement and easy movement of the device, making it easy to use.

[0020] 3. When using the truck bed to receive materials, the purification components absorb and clean up the rising dust, thereby preventing a large amount of powder from flying up and polluting the surrounding air environment when the materials fall and impact, avoiding the inhalation of large amounts of dust by the human body and causing harm to human health, effectively improving the air quality of the working environment and enhancing the protection of workers.

[0034] The present invention will be further described below with reference to embodiments.

[0035] Please see Figure 1-10This invention provides a non-traction metallurgical vehicle with multiple control modes, including a support plate 5. A truck bed 4 is fixed to the top side of the support plate 5. A horizontally arranged base plate 7 is arranged directly below the support plate 5. Multiple symmetrically distributed lower connecting rods 6 are fixed to the outer wall of the bottom end of the support plate 5. The lower connecting rods 6 slide through the base plate 7. Multiple symmetrically distributed support leg seats 10 are fixed to the bottom of the base plate 7. The bottom ends of the lower connecting rods 6 are connected to wheels 8. A pushing assembly 1 and a decompression assembly 2 that cooperate with the pushing assembly 1 are arranged below the truck bed 4. The pushing assembly 1 and the decompression assembly 2 cooperate to switch the lifting and lowering of the wheels 8 and the support leg seats 10. When loading materials, after the materials are put into the truck bed 4, the gravity of the materials drives the pushing assembly 1 to work. The pushing assembly 1 pushes the base plate 7 to move downward, so that the multiple wheels 8 move upward and are suspended in the air. This allows the multiple support leg seats 10 at the bottom of the base plate 7 to stably support the ground, thereby effectively improving the stability of the truck bed 4 when loading materials. To prevent damage to the wheels 8 due to severe vibration caused by the impact of metal blocks when the bucket 4 is used to receive materials, the following measures are implemented: First, the pressure relief component 2 releases the pressure of the material's weight on the support legs 10, allowing the weight of the material and the bucket 4 itself to push the multiple wheels 8 down to contact the ground. This allows the entire device to be easily moved using the multiple wheels 8. The pressure relief component 1 and pressure relief component 2 work together to easily switch between fixed placement and easy movement, making it convenient to use. Second, when the bucket 4 is used to receive materials, the purification component 3 absorbs and cleans up any rising dust, preventing large amounts of dust from being thrown up and polluting the surrounding air when materials fall. This also prevents the inhalation of large amounts of dust from harming human health, effectively improving the working environment and enhancing the protection of workers.

[0036] Further as Figure 4 , Figure 5 and Figure 6As shown, it is worth noting that the pressing assembly 1 includes a groove 101 formed in the bottom of the truck bed 4. A sliding and lifting bottom pressure plate 102 is provided in the groove 101. A first connecting post 104 that slides through the bottom of the truck bed 4 and the support plate 5 is fixed to the bottom of the bottom pressure plate 102. An outer sleeve 108 sleeved on the outside of the first connecting post 104 is fixed to the bottom of the support plate 5. A first piston plate 105 that fits tightly against the inner wall of the outer sleeve 108 is fixed to the bottom of the first connecting post 104. A second connecting post 107 inserted into the outer sleeve 108 is fixed to the top of the bottom plate 7. A second piston plate 106 that fits tightly against the inner wall of the outer sleeve 108 is fixed to the top of the second connecting post 107. When receiving materials, after the materials are put into the truck bed 4, the gravity of the materials presses the bottom pressure plate 102 down in the groove 101. When the bottom pressure plate 102 moves down, it drives the first piston plate 106 through the first connecting post 104. The stopper plate 105 presses down inside the outer sleeve 108. The middle section of the outer sleeve 108, located between the first piston plate 105 and the second piston plate 106, contains liquid, which can be water or oil. The first piston plate 105 squeezes the liquid inside the outer sleeve 108, thereby pushing the second piston plate 106 and the second connecting column 107 downward through hydraulic transmission. The second connecting column 107 drives the base plate 7 and multiple support legs 10 at the bottom of the base plate 7 to contact the ground, causing multiple wheels 8 to move upward and suspend in the air. This allows the multiple support legs 10 at the bottom of the base plate 7 to stably support the ground, thereby effectively improving the stability of the truck bed 4 when receiving materials. This avoids the problem of the wheels 8 being easily damaged due to violent vibration caused by the impact of metal blocks when the truck bed 4 is receiving materials, effectively reducing subsequent maintenance work on the wheels 8 and extending the overall service life of the wheels 8.

[0037] Further as Figure 6 and Figure 8 As shown, it is worth noting that a reset spring 103 is provided between the bottom side of the bottom pressure plate 102 and the bottom side of the groove 101. Multiple reset springs 103 are provided and are distributed at equal intervals. In actual operation, when the material in the hopper 4 is unloaded and the liquid in the decompression assembly 2 flows back into the outer sleeve 108, the multiple reset springs 103 push the bottom pressure plate 102 to move upward and reset, thereby assisting in the reset of the bottom pressure plate 102 and effectively improving the reset effect of the bottom pressure plate 102.

[0038] Further as Figure 2 , Figure 5 and Figure 7As shown, it is worth noting that the decompression assembly 2 includes a liquid-passing pipe 205 communicating with the inside of the outer sleeve 108. One end of the liquid-passing pipe 205 away from the outer sleeve 108 is connected to a connector pipe 202. An outer sleeve 201 is threaded onto the outer wall of the connector pipe 202. A connecting rod 207, inserted into the connector pipe 202, is fixed at the center of the top of the outer sleeve 201. A third piston plate 203, which fits tightly against the inner wall of the connector pipe 202, is fixed to the bottom end of the connecting rod 207. The liquid-passing pipe 205 and the connector pipe 202 contain the same liquid as the inside of the outer sleeve 108. After the material is filled, the outer sleeve 201 is rotated upwards, and the outer sleeve 201 is driven by the connecting rod 207. The third piston plate 203 moves upward within the connector pipe 202, drawing the liquid from the outer sleeve 108 into the liquid inlet pipe 205. This releases the pressure and limiting effect of the liquid in the outer sleeve 108 on the second piston plate 106, allowing the second piston plate 106 to move upward. This releases the pressure of the material's gravity on the support leg seat 10, allowing the weight of the material in the bucket 4 and the bucket 4's own weight to push the multiple wheels 8 down to contact the ground. This switches to multiple wheels 8 for landing, allowing the entire device to be easily moved via the multiple wheels 8, enabling convenient switching between easy movement and stable placement of the entire device.

[0039] Further as Figure 7 As shown, it is worth noting that a handle 204 is fixed to the top of the outer sleeve 201, and a rubber sleeve 206 is fitted onto the surface of the handle 204. In actual operation, the outer sleeve 201 is rotated by rotating the handle 204. The handle 204 has a long lever arm, and the rubber sleeve 206 can effectively increase the friction when gripping and rotating the handle 204, making the operation more effortless and convenient.

[0040] Further as Figure 2 and Figure 5 As shown, it is worth noting that a fixing plate 14 is fixed on the side of the base plate 7, and the liquid passage pipe 205 passes through the top side of the fixing plate 14 and is fixed to the fixing plate 14. In actual operation, the fixing plate 14 is used to assist in fixing the liquid passage pipe 205, which effectively reduces the shaking of the liquid passage pipe 205 and improves the stability of the operation.

[0041] Further as Figure 1 , Figure 9 and Figure 10As shown, it is worth noting that a dust removal purification component 3 is provided on the top of the truck bed 4. The purification component 3 includes a concave seat 301 fixed to the side of the top of the truck bed 4. A dust suction chamber 305 is provided inside the concave seat 301. A dust suction hole 304 communicating with the dust suction chamber 305 is provided on the side of the concave seat 301 near the opening at the top of the truck bed 4. Multiple dust suction holes 304 are provided and are equidistantly distributed. A connecting pipe 302 communicating with the dust suction chamber 305 is fixed to the outer surface of the concave seat 301. The top side of the support plate 5 A vacuum cleaner 303 is fixed on the surface. The output end of the vacuum cleaner 303 is connected to the end of the connecting pipe 302 away from the concave seat 301. When the hopper 4 is used to hold materials, the vacuum cleaner 303 creates a negative pressure in the connecting pipe 302 and the suction chamber 305, thereby absorbing and cleaning the rising dust through multiple suction holes 304. This prevents a large amount of powder from flying up and polluting the surrounding air environment when the material falls and impacts the air, and prevents the human body from inhaling a large amount of dust, which could harm human health. This effectively improves the working environment and enhances the protection of workers.

[0042] This solution includes the following working process: When receiving materials, after the materials are put into the hopper 4, the gravity of the materials presses the bottom pressure plate 102 down in the groove 101. When the bottom pressure plate 102 moves down, it drives the first piston plate 105 to press down in the outer sleeve 108 through the first connecting column 104. The middle section of the outer sleeve 108, located between the first piston plate 105 and the second piston plate 106, is filled with liquid, which can be water or oil, etc. The first piston plate 105 squeezes the liquid in the outer sleeve 108, thereby pushing the second piston through hydraulic transmission. The plate 106 and the second connecting column 107 move downwards, and the second connecting column 107 drives the base plate 7 and the multiple support legs 10 at the bottom of the base plate 7 to contact the ground, so that the multiple wheels 8 move upwards and are suspended in the air, so that the multiple support legs 10 at the bottom of the base plate 7 provide stable support for the ground contact; the vacuum cleaner 303 creates a negative pressure in the connecting pipe 302 and the vacuum chamber 305, so that the dust rising is absorbed and cleaned through the multiple vacuum holes 304, thereby avoiding a large amount of powder flying up and polluting the surrounding air environment when the material falls and makes an impact;

[0043] After the material is loaded, the outer sleeve 201 is rotated upwards. The outer sleeve 201, via the connecting rod 207, drives the third piston plate 203 upwards within the connector pipe 202. The upward-moving third piston plate 203 draws the liquid from the outer sleeve 108 into the liquid passage pipe 205, thus releasing the pressure and limiting effect of the liquid in the outer sleeve 108 on the second piston plate 106. This allows the second piston plate 106 to move upwards, thereby relieving the pressure exerted by the weight of the material on the support leg 10. The weight of the material inside the bucket 4 and the weight of the bucket 4 itself push the multiple wheels 8 to descend and contact the ground, thus switching to landing on the ground. At this time, the entire device can be easily moved by the multiple wheels 8, allowing the device to switch between convenient movement and stable placement. After the material inside the bucket 4 is unloaded, the outer sleeve 201 is rotated downwards to squeeze the liquid back into the outer sleeve 108. The multiple reset springs 103 push the bottom pressure plate 102 to move upwards and reset, thus assisting in the reset of the bottom pressure plate 102.

[0044] Further as Figure 2 and Figure 3 As shown, it is worth noting that the bottom ends of the two lower connecting rods 6 on the same side along the length of the truck bed 4 are rotatably connected to wheel axles 9. Wheels 8 are installed at both ends of wheel axles 9. A gear ring 13 is fixed to the side of one of the wheel axles 9. A mounting plate 19 is fixed to the bottom ends of the two lower connecting rods 6. A motor 18 is fixed to the side of the bottom end of the mounting plate 19. A battery electrically connected to the motor 18 is fixed to the mounting plate 19. A gear 17 that meshes with the gear ring 13 is fixed to the output end of the motor 18. When the truck bed 4 is filled with a lot of material or needs to go uphill... When the device is pushed, the motor 18 starts working, and the motor 18 drives the gear 17 to rotate. Through the cooperation of the gear 17 and the gear ring 13, the wheel axle 9 is driven to rotate, and the wheel axle 9 drives the wheel 8 to rotate. The rotating wheel 8 assists in the movement of the device, saving manpower. When the material inside the hopper 4 is small, the device can be directly pushed to move and transfer the material, saving energy. At the same time, the movement control of the device is more flexible, thus forming multiple control methods to drive and transfer materials. The appropriate method can be selected according to the actual use situation, making it highly practical.

[0045] Further as Figure 1 and Figure 3 As shown, it is worth noting that two symmetrically distributed diagonal rods 11 are fixed at one end of the support plate 5, and push handles 12 are fixed at the top of the two diagonal rods 11. In actual operation, the material is transferred by pushing the cart hopper 4 by holding and pushing the push handles 12, which is convenient for operation.

[0046] Further as Figure 2 , Figure 4 and Figure 5As shown, it is worth noting that one end of the truck bed 4 along its length is designated as the discharge port 16, and a baffle 15 is hinged inside the discharge port 16. By opening the baffle 15, it is convenient to pour out the material in the purification component 3 through the discharge port 16, making it easy to pick up the material.

[0047] In summary: After the material is fed into the bucket 4, the gravity of the material drives the pushing component 1 to work. The pushing component 1 pushes the bottom plate 7 downward, causing the multiple wheels 8 to move upward and suspend in the air. This allows the multiple support legs 10 at the bottom of the bottom plate 7 to stably support the ground, effectively improving the stability of the bucket 4 when receiving materials. This avoids the problem of the wheels 8 being easily damaged due to violent vibration caused by the impact of metal blocks when the bucket 4 is receiving materials, effectively reducing subsequent maintenance work on the wheels 8 and extending the overall service life of the wheels 8. After the material is loaded, the decompression component 2 releases the pushing force of the material's gravity on the support legs 10, allowing the gravity of the material inside the bucket 4 and the weight of the bucket 4 itself to push the multiple wheels 8 down to contact the ground, thus switching to the multiple wheels 8 landing. At this time, the entire device can be easily moved by the multiple wheels 8. The pushing component 1 and the decompression component 2 work together to achieve both fixed placement and convenient movement of the device. The device features convenient switching between mobile and manual operation. When using the hopper 4 to receive materials, the purification component 3 absorbs and cleans up any rising dust, preventing large amounts of dust from being thrown into the air and polluting the surrounding environment when materials fall. This also prevents people from inhaling large amounts of dust and harming their health, effectively improving the working environment and enhancing worker protection. When the hopper 4 is full of materials or needs to be pushed uphill, the motor 18 is started. The motor 18 drives the gear 17 to rotate, and the gear 17 and the gear ring 13 work together to drive the wheel axle 9 to rotate. The wheel axle 9 then drives the wheel 8 to rotate, which assists in moving the device and saves manpower. When the hopper 4 is empty, the device can be pushed directly to move and transfer materials, saving energy. The device's movement control is also more flexible, allowing for multiple control methods to drive and transfer materials, which can be selected according to the actual application. Overall, the device is highly practical.

[0048] The motor 18 can be purchased from the market. The motor 18 is equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
