Description

Technical Field

[0001] This invention relates to the field of metallurgical vehicle technology, and more particularly to a non-tractor-driven metallurgical vehicle. Background Technology

[0002] Metallurgy refers to the process and technology of extracting metals from minerals and processing them into metallic materials with certain properties through various processing methods. The manufactured metallic materials are generally transported using metallurgical vehicles to designated locations for storage.

[0003] The patent with publication number CN115742778A discloses a metallurgical vehicle powered by a new energy storage battery, including a metallurgical vehicle body. A cargo platform is fixedly installed on the top of the metallurgical vehicle body. The cargo platform includes a shell. The shell has a cavity with an open top. A support part is provided in the middle of the bottom wall of the cavity.

[0004] This patent allows for the placement of metal materials on a loading platform, enabling the movement of the metallurgical vehicle body for transport. After the metal materials are transported to a designated location, they need to be unloaded from the loading platform before the next transport can proceed. During the unloading process, the metallurgical vehicle body remains stationary, which wastes time and affects transport efficiency. Summary of the Invention

[0005] To overcome the drawback that the metal materials on the loading platform need to be unloaded before the next transport can be carried out, and that the metallurgical vehicle is stationary during the unloading process, which delays the transport and affects the transport efficiency, the purpose of this invention is to provide a non-traction metallurgical vehicle that can improve transport efficiency.

[0006] The technical solution of the present invention is as follows: a non-traction metallurgical vehicle, comprising a vehicle body, a dual-axis motor, traveling wheels, a battery, a steering motor, a rotating block, a steering wheel, a support frame, a cargo plate, a supporting mechanism, and a fixing mechanism. The dual-axis motor is connected to the bottom right side of the vehicle body, and both output shafts of the dual-axis motor are rotatably connected to the vehicle body. Travel wheels are connected to both output shafts of the dual-axis motor. The battery is connected to the top right side of the vehicle body, and the dual-axis motor and the battery are electrically connected. Steering motors are connected to the front and rear sides of the bottom left side of the vehicle body, and the steering motors are electrically connected to the battery. Rotating blocks are connected to the output shafts of the steering motors, and the tops of the rotating blocks are rotatably connected to the bottom of the vehicle body. Steering wheels are rotatably connected to the lower parts of the rotating blocks. A support frame is placed on the vehicle body, and a cargo plate for placing metal materials is connected to the top of the support frame. A supporting mechanism for supporting the cargo plate is provided on the top of the vehicle body, and a fixing mechanism for fixing the support frame is provided on the vehicle body.

[0007] Optionally, the supporting mechanism includes hydraulic cylinders and support blocks. Two hydraulic cylinders are connected to the left and right sides of the top of the vehicle body. The hydraulic cylinders are electrically connected to the battery, which can supply power to the hydraulic cylinders. Support blocks for supporting the cargo platform are connected to the telescopic rods of the hydraulic cylinders.

[0008] Optionally, the fixing mechanism includes a rectangular rod, a rack, a first elastic element, a movable frame, a plug rod, a gear, and a protrusion. Two rectangular rods are connected to the left and right sides inside the vehicle body. A rack is slidably mounted on each rectangular rod. A first elastic element connects the rectangular rod and the rack. A movable frame is connected to each rack. When the support block moves downward, it contacts the movable frame. Two plug rods for fixing the support frame are slidably mounted on the left and right sides inside the vehicle body. Grooves are symmetrically opened on the front and rear sides of the support frame. The plug rods are located in the grooves. Gears are sleeved on the outer side of each plug rod. The gears mesh with the rack. A spiral groove is opened on the inner side of each gear. A protrusion is connected to each plug rod. The protrusion is located in the spiral groove.

[0009] Optionally, it also includes a support mechanism for supporting the loading plate. The support mechanism includes support rods, sliders, slide bars and weights. Two support rods are rotatably connected to the front and rear sides of the bottom of the loading plate. Sliders are slidably provided on the top of the support rods. Slide bars are rotatably connected between the two sliders on the front side and between the two sliders on the rear side. Weights are connected to the slide bars.

[0010] Optionally, it also includes a stabilizing mechanism for pressing down the metal material. The stabilizing mechanism includes a guide frame, a guide rod, a pressure plate, a second elastic element, and a tilting frame. Guide frames are connected to both the front and rear sides of the vehicle body. Guide rods are connected inside the guide frames. Pressure plates are slidably provided between the guide rods. A second elastic element is connected between the pressure plate and the guide frame. A tilting frame is connected to the top right side of the cargo plate.

[0011] Optionally, it also includes a guide mechanism for guiding the cargo tray. The guide mechanism includes a first guide plate, a first roller, a second guide plate, a second roller, and a limiting plate. The first guide plates are connected to the front and rear sides of the left side of the vehicle body. The left sides of the two first guide plates are tilted in a direction away from each other. The first rollers are rotatably connected to the two first guide plates. The first rollers are in contact with the bottom of the cargo tray. The second guide plates are connected to the front and rear sides of the middle of the vehicle body. The second rollers are rotatably connected to the two second guide plates. The second rollers are in contact with the bottom of the cargo tray. A limiting plate is connected to the right side of the top of the vehicle body. The limiting plate is located on the left side of the battery.

[0012] Optionally, it also includes rubber sheets, with rubber sheets evenly spaced at the bottom of the pressure plate.

[0013] Optionally, it also includes a cylinder, with the cylinder connected to the top of the limiting plate, the cylinder's telescopic rod connected to the pressure plate, the cylinder electrically connected to the battery, and the battery capable of supplying power to the cylinder.

[0014] The beneficial effects of this invention are: 1. This invention uses a dual-axis motor to drive the walking wheels to rotate, thereby moving the vehicle body and transporting metal materials. After the metal materials are transported to the designated position, the extension rod of the hydraulic cylinder is shortened to lower the load plate. There is no need to wait for unloading, and the next transport can be carried out immediately, thereby improving the transport efficiency.

[0015] 2. The output shaft of the steering motor can drive the steering wheel to rotate and steer without the need for other equipment to traction. The battery can power the dual-shaft motor and the steering motor, eliminating the need for an external power source and allowing the vehicle to move flexibly.

[0016] 3. After the vehicle body is inserted into the support frame, the extension rod of the hydraulic cylinder is extended, causing the rack to move upward. The rack drives the gear to rotate in the opposite direction. Under the action of the spiral groove, the insertion rods on the front and rear sides can move towards each other, so that the insertion rods are inserted into the grooves, thereby fixing the support frame and preventing the support frame from shaking.

[0017] 4. After the vehicle body and support frame are completely separated, the support rod rotates downwards and contacts the ground. The support rod can support the front and rear sides of the cargo platform, reducing the weight borne by the cargo platform and improving the service life of the cargo platform.

[0018] 5. After the vehicle body is inserted into the support frame, the pressure plate can hold down the metal material on the load plate to prevent the metal material from shaking and make the metal material more stable. Under the action of the rubber plate, the pressure plate can prevent the metal material from being crushed.

[0019] 6. During the process of inserting the vehicle body into the support frame, the position of the cargo plate can be corrected by the action of the first guide plate and the second guide plate, so that the vehicle body can be inserted into the support frame in a straight line.

[0036] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0037] Example 1: A non-tractor-driven metallurgical vehicle, such as Figures 1-9 As shown, the vehicle includes a body 1, a dual-axis motor 2, wheels 3, a battery 4, a steering motor 5, a rotating block 6, a steering wheel 7, a support frame 71, a cargo plate 72, a supporting mechanism 8, and a fixing mechanism 9. The dual-axis motor 2 is bolted to the middle of the bottom right side of the body 1. Both output shafts of the dual-axis motor 2 are rotatably connected to the bottom of the body 1. Wheels 3 are connected to both output shafts of the dual-axis motor 2. The battery 4 is bolted to the top right side of the body 1. The dual-axis motor 2 and the battery 4 are electrically connected. The front and rear sides of the bottom left side of the body 1 are bolted together. A steering motor 5 is bolted to the vehicle body 1. The steering motor 5 is electrically connected to the battery 4. A rotating block 6 is connected to the output shaft of the steering motor 5. The top of the rotating block 6 is rotatably connected to the bottom of the vehicle body 1. A steering wheel 7 is rotatably connected to the bottom of the rotating block 6. A support frame 71 is placed on the vehicle body 1. A cargo plate 72 is bolted to the top of the support frame 71. The cargo plate 72 is used to place metal materials. A supporting mechanism 8 is provided on the top of the vehicle body 1. The supporting mechanism 8 is used to support the cargo plate 72. A fixing mechanism 9 is provided on the vehicle body 1. The fixing mechanism 9 is used to fix the support frame 71.

[0038] like Figure 1 and Figure 5 As shown, the supporting mechanism 8 includes a hydraulic cylinder 81 and a support block 82. The hydraulic cylinder 81 is symmetrically embedded on the left and right sides of the top of the vehicle body 1. The hydraulic cylinder 81 is electrically connected to the battery 4, and the battery 4 can supply power to the hydraulic cylinder 81. The top of the telescopic rod of the hydraulic cylinder 81 is connected to the support block 82 by bolts. The support block 82 is used to support the load plate 72 so that the support frame 71 does not contact the ground.

[0039] like Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the fixing mechanism 9 includes a rectangular rod 91, a rack 92, a first elastic element 93, a movable frame 94, a plug rod 95, a gear 97, and a protrusion 99. Rectangular rods 91 are symmetrically connected to the left and right sides of the vehicle body 1, and are vertically arranged. A rack 92 is slidably mounted on each rectangular rod 91. A first elastic element 93, which is a spring, connects the top of the rectangular rod 91 and the rack 92. A movable frame 94 is bolted to the upper part of each rack 92. 4. When the support block 82 moves downward, it will contact the moving frame 94. The inside of the vehicle body 1 is equipped with symmetrical sliding rods 95 on both the left and right sides. The support frame 71 has symmetrical grooves 96 on both the front and rear sides. The rods 95 are located in the grooves 96 to fix the support frame 71. Gears 97 are sleeved on the outside of the rods 95. The gears 97 mesh with the rack 92. The inner side of the gears 97 has a spiral groove 98. The rods 95 are connected to protrusions 99, which are located in the spiral grooves 98.

[0040] Workers control the extension rod of hydraulic cylinder 81 to move the support block 82 upwards, lifting the load plate 72 so that the support frame 71 does not contact the ground. Then, hydraulic cylinder 81 is closed, and the metal material is placed on the load plate 72. Next, the output shaft of the dual-axis motor 2 is rotated, driving the travel wheels 3 to rotate, thus moving the vehicle body 1 to transport the metal material. Controlling the output shaft of the steering motor 5 rotates the rotating block 6, which in turn drives the steering wheel 7 for steering. No other equipment is needed for traction; the battery 4 powers both the dual-axis motor 2 and the steering motor 5, eliminating the need for an external power source and allowing the vehicle body 1 to move flexibly. After the metal material is transported to the designated location... Turn off the dual-axis motor 2, then control the extension rod of the hydraulic cylinder 81 to shorten, causing the support block 82 to move downwards, so that the support block 82 and the carrying plate 72 are no longer in contact, and the carrying plate 72 is lowered, so that the support frame 71 contacts the ground. When the support block 82 moves downwards and contacts the moving frame 94, the support block 82 pushes the moving frame 94 downwards, and the moving frame 94 drives the rack 92 to move downwards. The first elastic element 93 is compressed, and the rack 92 drives the gear 97 to rotate. Under the action of the spiral groove 98, the protrusions 99 on the front and rear sides can move away from each other, thereby enabling the insertion rods 95 on the front and rear sides to move away from each other, so that the insertion rods 95 are removed from the grooves 96. Then, turn off the hydraulic cylinder 81. The operator then controls the output shaft of the dual-axis motor 2 to rotate, driving the walking wheels 3 to rotate and moving the vehicle body 1 to the transportation starting point. Since the support frame 71 is in contact with the ground, it will not move with the vehicle body 1, thus allowing the vehicle body 1 to detach from the support frame 71. The operator can place multiple loading plates 72 at the transportation starting point and place the metal materials on these loading plates 72. After the vehicle body 1 moves to the transportation starting point, the operator moves the vehicle body 1 to the right side of the loading plate 72 containing the metal materials and moves the vehicle body 1 towards the loading plate 72. The vehicle body 1 is inserted into the support frame 71, and then the dual-axis motor 2 is turned off. Subsequently, the operator controls the extension rod of the hydraulic cylinder 81 to extend, driving... The support block 82 moves upward, supporting the load plate 72 so that the support frame 71 does not contact the ground. The rack 92 moves upward under the action of the first elastic element 93. The rack 92 drives the gear 97 to rotate in the opposite direction. Under the action of the spiral groove 98, the protrusions 99 on the front and rear sides can move towards each other, thereby enabling the insertion rods 95 on the front and rear sides to move towards each other and insert into the grooves 96, thus fixing the support frame 71 and preventing it from shaking. Then the hydraulic cylinder 81 is closed, and the metal material continues to be transported. After the metal material is transported to the designated position, there is no need to wait for unloading, and the next transport can be carried out immediately, thereby improving the transport efficiency.

[0041] Example 2: Based on Example 1, such as Figure 10 and Figure 11As shown, it also includes a support mechanism 10 for supporting the carrying plate 72. The support mechanism 10 includes a support rod 101, a slider 102, a sliding rod 103, and a weight 104. The support rod 101 is symmetrically and rotatably connected to the front and rear sides of the bottom of the carrying plate 72. The top of the support rod 101 is provided with a slider 102 through a sliding groove. The two sliders 102 on the front side and the two sliders 102 on the rear side are rotatably connected to the sliding rod 103. The weight 104 is bolted to the left and right sides of the top of the sliding rod 103.

[0042] During unloading, the vehicle body 1 gradually separates from the support frame 71. When the vehicle body 1 and the support frame 71 are completely separated, the support rod 101 rotates downward under its own weight, and the support rod 101 contacts the ground. The weight block 104 increases the weight of the slide rod 103, allowing the slide rod 103 to move downward. The slider 102 slides downward on the support rod 101, and the slide rod 103 supports the support rod 101. The support rod 101 supports the front and rear sides of the load plate 72, reducing the weight borne by the load plate 72 and improving the service life of the load plate 72. When it is necessary to retract the support rod 101, the worker uses a tool to push the slide rod 103 upward, causing the support rod 101 to rotate upward. When the vehicle body 1 is inserted into the support frame 71, the worker can release the slide rod 103, and the support rod 101 falls onto the load plate 72.

[0043] like Figure 1 , Figure 12 and Figure 13 As shown, it also includes a stabilizing mechanism 11 for pressing down the metal material. The stabilizing mechanism 11 includes a guide frame 111, guide rods 112, pressure plate 113, second elastic element 114, tilting frame 115, and rubber plate 116. The front and rear sides of the vehicle body 1 are symmetrically connected to the guide frame 111 by bolts. The guide rods 112 are connected inside the guide frame 111. The guide rods 112 are vertically arranged. The pressure plate 113 is slidably arranged between the four guide rods 112. The second elastic element 114 is sleeved on the outside of the guide rods 112. One end of the second elastic element 114 is connected to the pressure plate 113, and the other end of the second elastic element 114 is connected to the guide frame 111. The second elastic element 114 is a spring. The front and rear sides of the top right side of the loading plate 72 are connected to the tilting frame 115 by bolts. The bottom of the pressure plate 113 is evenly spaced with rubber plates 116.

[0044] Workers can place metal materials on the loading plate 72, and then insert the vehicle body 1 into the support frame 71, causing the pressure plate 113 to move. When the pressure plate 113 contacts the tilting frame 115, the pressure plate 113 continues to move. Under the action of the tilting frame 115, the pressure plate 113 moves upward, and the second elastic element 114 stretches. When the pressure plate 113 and the tilting frame 115 are not in contact, the pressure plate 113 moves downward under the action of the second elastic element 114. The pressure plate 113 can press down the metal materials on the loading plate 72 to prevent the metal materials from shaking, making the metal materials more stable. The rubber plate 116 is in direct contact with the metal materials to prevent the pressure plate 113 from crushing the metal materials. Then, workers can transport the metal materials on the loading plate 72. When unloading is required, workers control the extension rod of the cylinder 13 to extend, driving the pressure plate 113 to move upward, so that the pressure plate 113 no longer presses down on the metal materials.

[0045] like Figure 1 and Figure 14 As shown, it also includes a guide mechanism 12 for guiding the cargo plate 72. The guide mechanism 12 includes a first guide plate 121, a first roller 122, a second guide plate 123, a second roller 124, and a limiting plate 125. The first guide plate 121 is bolted to both the front and rear sides of the left side of the vehicle body 1. The left sides of the two first guide plates 121 are inclined in a direction away from each other. The first roller 122 is evenly spaced and rotatably connected to the side of the two first guide plates 121 that is close to each other. The second guide plate 123 is bolted to both the front and rear sides of the middle of the vehicle body 1. The second roller 124 is evenly spaced and rotatably connected to the side of the two second guide plates 123 that is close to each other. The limiting plate 125 is bolted to the right side of the top of the vehicle body 1. The limiting plate 125 is located on the left side of the battery 4.

[0046] like Figure 15 As shown, it also includes a cylinder 13. The top center of the limiting plate 125 is bolted to the cylinder 13. The top of the telescopic rod of the cylinder 13 is connected to the bottom of the pressure plate 113. The cylinder 13 is electrically connected to the battery 4, and the battery 4 can supply power to the cylinder 13.

[0047] During the process of inserting the vehicle body 1 into the support frame 71, the first guide plate 121 will come into contact with the cargo plate 72. The left sides of the two first guide plates 121 are tilted away from each other, which can correct the position of the cargo plate 72. Under the action of the first guide plate 121 and the second guide plate 123, the vehicle body 1 can be inserted into the support frame 71 in a straight line. The first roller 122 and the second roller 124 can reduce friction and prevent wear between the vehicle body 1 and the cargo plate 72. The limiting plate 125 can limit the cargo plate 72 and prevent the cargo plate 72 from colliding with the battery 4.

[0048] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
