Referring to fig. 4, it should be noted that the tilting telescopic member 210 and the lifting swing arm 220 are also power sources for tilting and lifting the hopper 240 while providing support for the hopper 240. When the materials are poured, the hopper 240 is required to turn, so that an included angle is formed between the hopper 240 and the ground to realize the pouring of the materials, when the hopper 240 turns, the lifting swing arm 220 is kept static, the turning telescopic piece 210 extends out to lift one end of the hopper 240 connected with the turning telescopic piece 210, and at the moment, one end of the hopper 240 connected with the turning telescopic piece 210 turns around a hinge point of the hopper 240 and the lifting swing arm 220 to realize the pouring of the materials;

referring to fig. 3 and 5, when a material needs to be loaded into the hopper 240, in order to reduce the difficulty of loading the material, the hopper 240 needs to start the lifting function, when the hopper 240 performs a lifting action, the tilt extension member 210 and the lifting actuator 230 are simultaneously started, and when the lifting actuator 230 is started, the lifting swing arm 220 is driven to rotate, because the lifting swing arm 220 is rotatably disposed on the base frame 200, a hinge point between the lifting swing arm 220 and the hopper 240 rotates around a connection point between the lifting swing arm 220 and the base frame 100, i.e., a motion trajectory of the hinge point between the lifting swing arm 220 and the hopper 240 is circular, so that the hinge point between the lifting swing arm 220 and the hopper 240 continuously approaches the ground during the motion process, i.e., one end of the hopper 240 connected to the lifting swing arm 220 moves in a direction approaching the ground, and at the same time, the tilt extension member 210 cooperates with the lifting swing arm 220 to perform an extending action, so that one end, thus, under the cooperative action of the turnover telescopic part 210 and the lifting swing arm 220, the hopper 240 is moved to be attached to the ground under the condition that the hopper 240 does not deflect, so that an operator can fill materials to be transferred into the hopper 240 conveniently, after the hopper 240 is filled with the materials, the turnover telescopic part 210 and the lifting driver 230 are started again at the same time, the lifting driver 230 drives the lifting swing arm 220 to rotate reversely, in the process of reversing the lifting swing arm 220, a hinge point of the lifting swing arm 220 and the hopper rotates around a connecting point of the lifting swing arm 220 and the underframe, at the moment, the hinge point of the lifting swing arm 220 and the hopper 240 moves towards the direction far away from the ground, namely, one end of the hopper 240 connected with the lifting swing arm 220 is lifted, meanwhile, the turnover telescopic part 210 cooperates with the lifting swing arm 220 to retract, so that the end of the hopper 240 connected with the turnover telescopic part 210, that is, under the cooperation of the tilting telescopic member 210 and the lifting swing arm 220, the hopper 240 is lifted back to the initial height without deflecting, that is, the hopper 240 leaves the ground, and at this time, the material can be transported to the target site through the transporter body 400. Through mutual cooperation of the turnover telescopic part 210 and the lifting swing arm 220, turnover and lifting actions of the hopper 240 are realized, available space on the underframe 100 is saved, and the upper limit of the loading of the transport vehicle is improved.

Referring to fig. 2, the chain type reinforcing mechanism 300 includes a drag chain traction module 310 and a support cantilever 320, the drag chain traction module 310 is embedded in the bottom chassis 100, the support cantilever 320 is installed on the drag chain traction module 310, the support cantilever 320 is attached to the bottom of the hopper 240, and the drag chain traction module 310 is used for driving the support cantilever 320 to ascend or descend. The supporting cantilever 320 is located in the hollow area 110, two ends of the supporting cantilever 320 are indirectly connected with the underframe 100 through the drag chain traction module 310, the underframe 100 is tensioned through the supporting cantilever 320, the deformation of the underframe 100 when the transport vehicle carries materials is reduced, the bearing capacity of the underframe 100 is further improved, the supporting cantilever 320 has the capacity of moving along with the hopper 240 through the drag chain traction module 310, and therefore it is ensured that the supporting cantilever 320 does not interfere with the lifting action of the hopper 240, and the integral loading capacity of the transport vehicle is improved.

Referring to fig. 2, it can be understood that, in order to satisfy the feature that the hopper 240 can achieve the coexistence of the lifting function and the turning function, the hollow-out region 110 needs to be disposed on the underframe 100, however, due to the disposition of the hollow-out region 110, the underframe 100 becomes an unclosed "Contraband" shaped support structure, which results in the weakening of the structural strength of the underframe 100, the stress at the upper corner position of the underframe 100 is concentrated and easily dispersed, i.e. the load-carrying capacity of the transport vehicle 10 with the swivel-type car is limited, and the ability of the transport vehicle 10 with the swivel-type car to carry a load on a bumpy road surface is also reduced, and the chain-type reinforcing mechanism 300 can solve the above problem well, the supporting arm 320 is disposed on the underframe 100 through the drag chain traction module 310, and the supporting arm 320 is suspended as a cross beam in the hollow-out region 110, when the transport vehicle 10 with the swivel-type, the pressure generated by the material in the hopper 240 and the torsion force applied to the chassis 100 during the running process of the transport vehicle are transmitted to the supporting cantilevers 320, and the pressure applied to the chassis 100 is shared by the supporting cantilevers 320, so that the overall pressure resistance of the chassis 100 is improved, and the load capacity of the transport vehicle 10 with a swivel-bucket type compartment is further improved.

Referring to fig. 7 and 8, in an embodiment, in order to improve the flexibility of the chain-type reinforcing mechanism 300 and facilitate the lifting movement of the hopper 240, the two opposite inner sidewalls of the hollow area 110 are provided with a movable groove 111, the tow chain traction module 310 is accommodated in the bottom chassis 100, so that the connection between the bottom chassis 100 and the chain-type reinforcing mechanism 300 is more compact, and one side of the movable groove 111 facing the ground is provided with a descending opening 111a, and the tow chain traction module 310 can slide out from the descending opening 111a, so that the support cantilever 320 descends to approach the ground, and it is ensured that the support cantilever 320 does not need to be taken out when the hopper 240 is lifted, i.e. the support cantilever 320 can be connected with the bottom chassis 100 in the whole course, and the external.

Referring to fig. 7 and 8, further, the tow chain traction module 310 includes a main connection plate 311, a linear motor 312 and a chain 313, the main connection plate 311 is accommodated in the movable slot 111, the chain 313 is mounted on the main connection plate 311, the support cantilever 320 is mounted on the chain 313, and the linear motor 312 pushes the main connection plate 311 to move forward or backward for driving the support cantilever 320 to ascend or descend. The two ends of the chain 313 are respectively connected with the supporting cantilever 320 and the main connecting plate 311, in an initial state, the chain 313 is completely accommodated in the movable groove 111, at the moment, the point where the chain 313 is connected with the supporting cantilever 320 is positioned in the movable groove, at the moment, the supporting cantilever 320 is positioned at the highest point, when the hopper 240 descends, the linear motor 312 moves the main connecting plate 311 towards the direction close to the descending opening 111a, the chain 313 approaches the descending opening 111a, and when the connecting point of the chain 313 and the supporting cantilever 320 moves to the descending opening 111a, under the gravity action of the hopper 240, the connecting point of the chain 313 and the supporting cantilever 320 passes through the descending opening 111a to leave the movable groove 111 and moves towards the ground, and in the process, the chain 313 continuously passes through the descending opening 111a to extend out of the movable groove 111; until the hopper 240 comes into contact with the ground, at which point the support boom 320 moves to its lowest point.

Referring to fig. 7 and 8, similarly, when the hopper 240 is lifted, the linear motor 312 drives the main connecting plate 311 to move away from the descending opening 111a, at this time, the main connecting plate 311 pulls the chain 313 to continuously retract into the movable groove 111 along the descending opening 111a, the supporting cantilever 320 connected to the chain 313 also rises along with the retraction of the chain 313 until the chain is completely accommodated into the movable groove 111, the supporting cantilever 320 recovers the initial height, and the supporting cantilever 320 is driven to ascend and descend along with the hopper 240 by the pushing and pulling of the linear motor 312, so as to ensure the integrity of the lifting function.

Referring to fig. 9 and 10, in another embodiment, in order to save the internal space of the rack 100 and improve the carrying capacity of the rack 100, the drag chain traction module 310 includes a drag chain 314, a winding motor and a receiving sleeve 315, the winding motor is installed in the movable slot 111, the output end of the winding motor is connected to the receiving sleeve 315, the winding motor is used for driving the receiving sleeve 315 to rotate, one end of the drag chain 314 is installed on the receiving sleeve 315, the drag chain 314 is wound on the outer sidewall of the receiving sleeve 315, a supporting cantilever 320 is installed on the other end of the drag chain, and the supporting cantilever 320 is located right above the descending opening 111 a. When the hopper 240 descends, the winding motor starts to drive the accommodating sleeve 315 to rotate for unwinding, the drag chain 314 wound on the accommodating sleeve 315 passes through the descending opening 111a and extends out of the movable groove 111, so that the supporting cantilever 320 can descend along with the hopper 240, and similarly, when the hopper 240 ascends, the winding motor drives the accommodating sleeve 315 to turn over for winding, so that the drag chain 314 is continuously wound on the accommodating sleeve 315, and the supporting cantilever 320 is continuously lifted along with the winding of the drag chain 314 until the initial height is recovered. Because the supporting cantilever 320 is lifted and lowered by rolling and unwinding the drag chain 314 through the accommodating sleeve 315, the main action is to rotate the accommodating sleeve, so that the inner space of the chassis 100 is not occupied, and more space can be made for accommodating other components.

Referring to fig. 5, it can be understood that, in order to improve the pressure-bearing capacity of the chain type reinforcing mechanism 300, a hydraulic pull rod 330 may be additionally provided on the basis of the structure of the drag chain traction module 310 to enhance the structural strength of the chain type reinforcing mechanism 300, the auxiliary component 500 includes the hydraulic pull rod 330 hinged to the base frame 100, an output end of the hydraulic pull rod 330 is connected to the support cantilever 320, when the support cantilever 320 descends, the hydraulic pull rod 330 is started and extends out along with the hydraulic pull rod, and the hydraulic pull rod distributes the pulling force acting on the drag chain 314 or the chain 313, so as to improve the tensile capacity of the drag chain 314 or the chain 313, and further improve the pressure-bearing capacity of the chain type reinforcing mechanism 300.

Referring to fig. 2, in the actual production process, the single loading amount is also a factor affecting the transportation efficiency of the transportation vehicle 10 with the hopper type compartment, and the transportation efficiency can be improved by transporting more materials in one round trip. Therefore, the structure of the hopper 240 needs to be optimized, and in one embodiment, the hopper 240 has a stepped structure, and the width of the upper end of the hopper 240 is greater than that of the lower end of the hopper 240. That is, the cross section of the hopper 240 is in an inverted convex shape, when the hopper 240 descends to be attached to the ground, the upper half part of the hopper 240 is still located above the underframe 100, and the upper half part of the hopper 240 does not need to penetrate through the hollow area 110, so that the hopper 240 is set to be in a larger width without interfering with the underframe 100, the cargo capacity of the hopper 240 can be increased, and the carrying capacity of the hopper can be improved.

Referring to fig. 3, further, since the hopper 240 is a movable structure and has a large range of movement, when the transport vehicle is carrying cargo, the pressure acting on the tilting telescopic member 210 and the lifting swing arm 220 is large, and the wear amount on the tilting telescopic member 210 and the lifting swing arm 220 is large, which results in a short service life of the tilting telescopic member 210 and the lifting swing arm 220, in order to solve the problem, a supporting step 241 is disposed on one side of the hopper 240 close to the underframe 100, and the supporting step 241 is used for abutting against the underframe 100. The supporting step 241 is used to abut against the bottom frame 100, and thus, part of the pressure on the hopper 240 is directly distributed to the bottom frame 100, thereby reducing the pressure directly acting on the overturning telescopic member 210 and the lifting swing arm 220, optimizing the stress condition on the transport vehicle 10 with the bucket type compartment, and reducing the loss rate of the parts on the transport vehicle 10 with the bucket type compartment.

Referring to fig. 2, further, since the turning expansion member 210 and the lifting swing arm 220 both involve rotation during operation, when the transportation vehicle 10 with the bucket type compartment moves, the hopper 240 is prone to shaking, which may cause the material in the hopper 240 to spill when shaking a large amount, and the shaking process causes great loss to the parts on the transportation vehicle 10 with the bucket type compartment, and causes a series of problems such as unstable running of the transportation vehicle 10 with the bucket type compartment, and therefore, the outer sidewall of the hopper 240 is provided with a limit groove 242, and the lifting swing arm 220 is used for abutting against the inner sidewall of the limit groove 242. The elevating driver 230 applies a thrust to keep the elevating swing arm 220 in close contact with the inner wall of the stopper groove 242, and the swing range of the hopper 240 can be effectively reduced by the thrust applied by the elevating driver 230 when the transportation vehicle 10 having the swinging hopper car moves.

Referring to fig. 1 and 2, in order to improve the material lifting capability of the swinging hopper car 200, the turning telescopic member 210 includes a hinge base 211 and a hydraulic cylinder 212, the hinge base 211 is mounted on the edge of the underframe 100, the body of the hydraulic cylinder 212 is hinged to the hinge base 211, the output end of the hydraulic cylinder 212 is hinged to the hopper 240, and the hydraulic cylinder 212 enhances the upper limit of the weight of the material lifted by the swinging hopper car 200.

Referring to fig. 1 and 2, further, in order to protect vulnerable components on the transportation vehicle 10 having the swinging hopper type compartment, a lifting protection frame 120 is disposed on the underframe 100, a lifting swing arm 220 is rotatably disposed in the lifting protection frame 120, a lifting driver 230 is hinged to a first end of the lifting swing arm 220, a second end of the lifting swing arm 220 is hinged to a hopper 240, a first end of the lifting swing arm 220 is bent toward a side away from the turnover telescopic element 210, so that an included angle is formed between the first end of the lifting swing arm 220 and a main body of the lifting swing arm 220, and a bent portion of the lifting swing arm 220 is a connection point of the lifting swing arm 220 and the lifting protection frame 120, and since the included angle is formed between the first end of the lifting swing arm 220 and the main body of the lifting swing arm 220, the lifting driver 230 drives the lifting swing arm 220 to.

Further, referring to fig. 1 and 11, in the actual use process, when the car 240 is supported by the turnover telescopic member 210, the lifting swing arm 220 and the lifting driver 230 alone, when the car 240 moves on the dump truck 20, the torsion of the car 240 acting on the lifting swing arm 220 and the turnover telescopic member 210 is large, the practical life of the turnover telescopic member 210 and the lifting swing arm 220 is shortened, and the car 240 shakes significantly when driving on a bumpy road surface, which is not beneficial for transporting goods, therefore, in an embodiment, the turning car body 200 further includes a limiting support assembly 250, the limiting support assembly 250 includes an upper limiting rod 251 and a lower supporting rod 252, the upper limiting rod 251 is mounted on the outer side wall of the car, the lower supporting rod 252 is mounted on the bottom frame, the lower supporting rod 252 is used for supporting the upper limiting rod 251, and an anti-turning boss 253 is disposed on the end surface of the lower supporting rod, the anti-reverse boss 253 is used for abutting against the upper limit rod 251. It should be noted that, because the movement trajectory of the car bucket 240 in the present invention is actually circular arc when the car bucket is lifted, a certain displacement occurs in the horizontal direction during the lifting and lowering processes, that is, the movement trajectory of the car bucket 240 has the highest point and the lowest point, the car bucket 240 starts to descend after passing through the highest point, and similarly, the car bucket 240 starts to ascend after passing through the lowest point. Thus, in the initial state, the upper limit rod 251 abuts against the lower support rod 252, the lower support rod 252 provides a supporting force for the upper limit rod 251, that is, the lower support rod 252 provides a supporting force for the car bucket 240, at this time, the weight of the car bucket 240 is mainly distributed on the lower support rod 252 and the bottom frame 100, the torsion applied to the turnover telescopic member 210 and the lifting swing arm 220 by the car bucket and the goods in the car bucket is effectively reduced, the service lives of the turnover telescopic member 210 and the lifting swing arm 220 are effectively prolonged, the car bucket 240 is supported on the bottom frame 100 through the cooperation of the upper limit rod 251 and the lower support rod 252, the anti-turnover boss 253 abuts against the side wall of the upper limit rod 251, and the car bucket 240 is prevented from being turned over; when the car 240 descends, the turning telescopic part 210 and the lifting driver 230 are started, the lifting swing arm 220 starts to swing, the car 240 starts to move along an arc-shaped track, firstly, the car 240 is lifted for a short distance until the car 240 moves to the highest point of the motion track, the upper limiting rod 251 is lifted in the process, the lifting height of the upper limiting rod is greater than the height of the anti-reverse boss 253, namely, the upper limiting rod 251 leaves the lower supporting rod 252 in the process, and when the car 240 moves to the highest point of the motion track, the car starts to descend along the motion track until the car descends to the right position; after the loading is finished, the car 240 rises, the turning telescopic part 210 and the lifting driver 230 are started, the turning telescopic part 210 begins to contract, the lifting driver 230 drives the lifting swing arm 220 to swing reversely, the car 240 begins to rise along the motion track, the car 240 reaches the highest point of the motion track, at this time, the upper limiting rod 251 is lifted to be higher than the lower supporting rod 252 along with the car 240, and the lower end of the upper limit rod 251 is located above the anti-reverse boss 253, the compartment 240 starts to descend after moving to the highest point of the motion track, at this time, the upper limit rod 251 is moved to abut against the lower support rod 252, namely, the lower end surface of the upper limiting rod 251 and the upper end surface of the lower supporting rod 252 are mutually attached, and at this time, the anti-reverse boss 253 is abutted against the side wall of the upper limiting rod 251, to prevent the upper limit lever 251 from being displaced toward the anti-reverse boss 253, i.e., to prevent the bucket 240 from being displaced toward the anti-reverse boss 253.
