Description

Technical Field

[0001] This utility model relates to the field of special vehicle technology, and in particular to a U-shaped tanker truck. Background Technology

[0002] The slag-carrying car, as a special vehicle, has functions such as carrying, releasing, tipping, dumping slag, and transporting slag. Therefore, it is used as the main production equipment on the smelting slag treatment production line. Compared with rail transport vehicles, it has the characteristics of lower investment, smaller footprint, greater maneuverability, and greater safety and reliability. Therefore, it is widely used in steel furnace smelters and non-ferrous smelters at home and abroad for the transfer and treatment of smelting slag.

[0003] The current U-shaped tanker truck uses a tilting cylinder to drive the slag tank to tilt with the working mechanism to achieve the slag dumping operation. When the working mechanism tilts to a certain angle, the weight of the slag tank and the working mechanism will accelerate the extension of the piston rod on the tilting cylinder. If the tilting cylinder continues to extend the piston rod after reaching its own stroke, it is easy to cause damage to the tilting cylinder, disengagement or penetration, and thus a tilting accident. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a U-shaped tanker truck that can prevent tipping accidents during slag dumping operations.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides a U-shaped tank-holding vehicle, including a tractor unit, a rear frame, and a flexible protective rope. The tractor unit is connected to the rear frame, and a U-shaped working arm capable of locking the slag tank is hinged on the rear frame. The U-shaped working arm deflects towards the rear of the vehicle under the action of a tilting cylinder. The flexible protective rope is limited on the tractor unit and can slide along the slide groove of the tractor unit. The two ends of the flexible protective rope are symmetrically hinged to the U-shaped working arm. When the tilting cylinder retracts to its minimum stroke, the flexible protective rope is in a relaxed state; before the tilting cylinder extends to its maximum stroke, the flexible protective rope is in a taut state.

[0007] Preferably, the tractor unit is connected to the rear frame via a connecting body. The connecting body is hinged to the tractor unit and can swing to both sides of the vehicle body. A steering cylinder is provided on each side of the connecting body. One end of the steering cylinder is hinged to the tractor unit, and the other end of the steering cylinder is hinged to the side of the connecting body.

[0008] Preferably, the rear frame has an opening at the rear to form a U-shaped frame, and the flexible protective rope is located in the inner space of the rear frame when relaxed. The opening of the U-shaped working arm also faces the rear of the vehicle. A tilting cylinder is installed on each of the two oppositely spaced side plates of the rear frame. The piston rods of the two tilting cylinders are respectively hinged to the U-shaped working arm and drive the U-shaped working arm to tilt towards the rear of the vehicle.

[0009] Preferably, a rear support axle is hinged to the rear frame, and a lifting cylinder is installed on each of the two oppositely spaced side plates of the rear frame. The piston rods of the two lifting cylinders are respectively hinged to the rear support axle and drive the rear frame to rise and fall.

[0010] Preferably, the U-shaped working arm is provided with a pair of slag pot locking assemblies. The slag pot locking assembly includes a locking plate and a locking plate cylinder. Both the locking plate and the locking plate cylinder are hinged to the U-shaped working arm, and the piston rod end of the locking plate cylinder is hinged to the locking plate and drives the locking plate to lock / unlock.

[0011] Preferably, it also includes a pressure plate, which is fixed to the tractor head at intervals to form a limiting space, and the flexible protective rope is limited within the limiting space.

[0012] Preferably, it also includes a pulley, which is fixed within the limiting space, and the flexible protective rope can be slidably embedded in the groove of the pulley.

[0013] Preferably, the middle part of the pressure plate is connected and fixed to the pulley, and the two ends of the pressure plate are connected and fixed to the tractor head through studs. The pressure plate, the studs at both ends, and the tractor head together form a limiting space.

[0014] Preferably, it also includes a protective cover, which is disposed on the tractor head and blocks the space between the pressure plate and the rear frame.

[0015] Preferably, two mounting seats are symmetrically arranged on the U-shaped working arm, and connectors are installed at both ends of the flexible protective rope. The two ends of the flexible protective rope are hinged to the mounting seats on the U-shaped working arm through the connectors.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The U-shaped tanker truck of this utility model can provide safety protection through a flexible protective rope. During the slag dumping operation, when the tilting cylinder drives the U-shaped working arm and the slag tank on the U-shaped working arm to tilt to the rear of the truck, the flexible protective rope moves with the U-shaped working arm. When the tilting cylinder still has an appropriate amount of travel left, the flexible protective rope is in a taut state to prevent the piston rod of the tilting cylinder from continuing to extend, thereby preventing the tilting cylinder from being damaged, dislodged, or penetrated, and avoiding the tilting accident of the slag tank and the U-shaped working arm.

[0040] See Figure 1 , Figure 2 and Figure 5 This embodiment provides a U-shaped tank-holding vehicle, including a tractor unit 1, a rear frame 2, and a flexible protective rope 3. The tractor unit 1 is connected to the rear frame 2, and a U-shaped working arm 5 capable of locking the slag tank 4 is hinged on the rear frame 2. The U-shaped working arm 5 is deflected towards the rear of the vehicle under the action of the tilting cylinder 6. The flexible protective rope 3 is limited on the tractor unit 1 and can slide along the slide groove 1301 of the tractor unit 1. The two ends of the flexible protective rope 3 are symmetrically hinged to the U-shaped working arm 5. When the tilting cylinder 6 is retracted to its minimum stroke, the flexible protective rope 3 is in a relaxed state. Before the tilting cylinder 6 is extended to its maximum stroke, the flexible protective rope 3 is in a taut state.

[0041] In this embodiment, the U-shaped tanker truck can provide safety protection through the flexible protective rope 3. During the slag dumping operation, when the tilting cylinder 6 drives the U-shaped working arm 5 and the slag tank 4 on the U-shaped working arm 5 to tilt to the rear of the truck, the flexible protective rope 3 moves together with the U-shaped working arm 5. When the tilting cylinder 6 still has an appropriate amount of stroke reserved, the flexible protective rope 3 is in a taut state to prevent the piston rod of the tilting cylinder 6 from continuing to extend, thereby preventing the tilting cylinder 6 from being damaged, dislodged, or penetrated, and avoiding the tilting accident of the slag tank 4 and the U-shaped working arm 5.

[0042] Preferably, see Figure 1 and Figure 2 The tractor unit 1 is connected to the rear frame 2 via a connecting body 7. The connecting body 7 is hinged to the tractor unit 1, allowing it to swing to both sides of the vehicle body. A steering cylinder 8 is installed on each side of the connecting body 7. One end of the steering cylinder 8 is hinged to the tractor unit 1, and the other end is hinged to the side of the connecting body 7. In this embodiment, the U-shaped tanker truck is steered by the tractor unit 1, and the two steering cylinders 8 can extend and retract according to the direction of the vehicle body's rotation, thereby further improving the vehicle's steering flexibility.

[0043] Preferably, see Figures 1 to 3 The rear frame 2 has an opening at the rear to form a U-shaped frame. The flexible protective rope 3 is located in the inner space of the rear frame 2 when it is relaxed. The opening of the U-shaped working arm 5 also faces the rear of the vehicle. The rear frame 2 has a tilting cylinder 6 installed on each of the two opposite side plates. The piston rod ends of the two tilting cylinders 6 are respectively hinged to the U-shaped working arm 5 and drive the U-shaped working arm 5 to tilt towards the rear of the vehicle.

[0044] When it is necessary to transfer the slag container 4, the slag container 4 can enter from the rear of the vehicle and be locked by the U-shaped working arm 5. Then, the U-shaped container truck in this embodiment can move the slag container 4 together. In addition, the flexible protective rope 3 is located in the inner space of the rear frame 2 when it is relaxed, which can protect the flexible protective rope 3 and prevent it from being damaged or broken due to friction, collision or other factors. The two tilting cylinders 6 can ensure the stability of the U-shaped container truck during slag dumping operation and ensure safety.

[0045] Preferably, see Figure 1 and Figure 2 The rear frame 2 is hinged with a rear support bridge 9. A lifting cylinder 10 is installed on each of the two oppositely spaced side plates of the rear frame 2. The piston rods of the two lifting cylinders 10 are hinged to the rear support bridge 9 and drive the rear frame 2 to rise and fall. After the slag pot 4 is locked onto the U-shaped working arm 5, the rear frame 2 is lifted by the lifting cylinders 10, thus raising the U-shaped working arm 5 together with the slag pot 4, thereby lifting the slag pot 4 off the ground for transport.

[0046] Preferably, see Figure 1 and Figure 2 The U-shaped working arm 5 is equipped with a pair of slag pot locking assemblies, which include a locking plate 501 and a locking plate cylinder 502. Both the locking plate 501 and the locking plate cylinder 502 are hinged to the U-shaped working arm 5, and the piston rod end of the locking plate cylinder 502 is hinged to the locking plate 501, driving the locking plate 501 to lock / unlock. After the slag pot 4 enters the opening of the U-shaped working arm 5, the pair of slag pot locking assemblies on the U-shaped working arm 5 can drive the locking plate 501 to lock onto the two trunnions of the slag pot 4 through the locking plate cylinder 502, thereby completing the locking of the slag pot 4.

[0047] Preferably, see 3. Figure 5 and Figure 6 The U-shaped tank-holding vehicle in this embodiment also includes a pressure plate 11, which is fixed to the tractor head 1 at intervals to form a limiting space 12. The flexible protective rope 3 is limited within the limiting space 12. The existence of the limiting space 12 can provide a certain degree of protection for the flexible protective rope 3, preventing it from directly contacting sharp edges or other hard objects during the pulling process, and reducing wear and damage to the flexible protective rope 3.

[0048] Preferably, see Figure 3 , Figure 5 and Figure 6 The U-shaped tank-carrying cart in this embodiment also includes a pulley 13, which is fixed within the limiting space 12. The flexible protective rope 3 can be slidably embedded in the groove 1301 of the pulley 13. The presence of the groove 1301 enables the tension at both ends of the flexible protective rope 3 to be more uniform, reducing uneven deformation of the flexible protective rope 3 during the stress process and extending the service life of the flexible protective rope 3.

[0049] Better, see Figure 6 In this embodiment, the portion of pulley 13 facing the rear frame 2 is cut off to form a semi-circular shape. Since pulley 13 is only used to provide the groove 1301 for the flexible protective rope 3 to slide, and pulley 13 itself does not rotate, it is not necessary to use a full circular shape to save costs.

[0050] Preferably, see Figure 5 The middle part of the pressure plate 11 is connected and fixed to the pulley 13, and the two ends of the pressure plate 11 are connected and fixed to the tractor head 1 through studs 14. The pressure plate 11 and the studs 14 at both ends together with the tractor head 1 form a limiting space 12.

[0051] Better, see Figure 5 In this embodiment, the pressure plate 11 is connected and fixed to the pulley 13 by fastening bolts 15.

[0052] Preferably, see Figure 1 and Figure 2 The U-shaped tanker truck in this embodiment also includes a protective cover 16, which is mounted on the tractor head 1 and blocks the space between the pressure plate 11 and the rear frame 2. The protective cover 16 can protect the pressure plate 11 and prevent it from being burned by the liquid slag splashed out from the slag tank 4.

[0053] Better, see Figure 1 and Figure 5 In this embodiment, both the pressure plate 11 and the protective cover 16 are mounted on the connecting body 7 of the tractor head 1.

[0054] Preferably, see Figure 2 , Figure 3 and Figure 4 Two mounting seats 503 are symmetrically arranged on the U-shaped working arm 5. The two ends of the flexible protective rope 3 are respectively equipped with connectors 301. The two ends of the flexible protective rope 3 are hinged to the mounting seats 503 on the U-shaped working arm 5 through the connectors 301.

[0055] Preferably, in this embodiment, the flexible protective rope 3 is a steel wire rope, and the joint 301 on the flexible protective rope 3 is an open casting joint. The open casting joint is hinged to the mounting seat 503 on the U-shaped working arm 5 through a pin, and the pin is axially limited on the mounting seat 503 by a cotter pin.

[0056] The U-shaped tanker truck of this invention has a simple structure, is easy to manufacture and install, has high reliability, and can improve the safety and stability of the vehicle body during operation.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
