[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The present invention provides an intelligent flatbed traction device for a new energy semi-trailer.

[0054] First embodiment.

[0055] Please refer to Figures 1 to 3In the first embodiment of the present invention, the intelligent flatbed traction device of the new energy semi-trailer includes:

[0056] A frame 1, wherein the frame 1 is provided with an adjustment slide hole 101;

[0057] A wheel set 2, wherein the wheel set 2 is mounted at the bottom of the frame 1;

[0058] A hydraulic support member 3, wherein the hydraulic support member 3 is fixedly mounted at the bottom of the vehicle frame 1;

[0059] A mounting mechanism 4, wherein the mounting mechanism 4 is fixedly mounted on the vehicle frame 1;

[0060] A first telescopic member 5, wherein the first telescopic member 5 is fixedly mounted on the mounting mechanism 4;

[0061] The traction assembly 6 includes a connecting box 61 and a traction pin 62. The connecting box 61 is slidably installed in the frame 1. The telescopic part of the first telescopic member 5 passes through the mounting mechanism 4 and is fixedly connected to the connecting box 61. The top of the traction pin 62 passes through the adjusting slide hole 101 and is connected to the connecting box 61.

[0062] The frame 1 is a flatbed semi-trailer body structure, and can be docked with a tractor head through the tractor pin 62 , so that the tractor head can tow the frame 1 as a whole through the tractor pin 62 .

[0063] The wheel set 2 is a multi-wheel structure, and the wheel structure is equipped with an independent braking system, and the wheel set 2 is braked by the braking system to facilitate braking when the frame 1 is parked alone to prevent the frame 1 from slipping.

[0064] The first telescopic member 5 is used to conveniently drive the connection box 61 to move and adjust. When the connection box 61 moves, the traction pin 62 is simultaneously driven to move and adjust on the frame 1, so as to facilitate the adjustment of the position of the traction pin 62 at the head of the frame 1, thereby adjusting the connection position between the frame 1 and the traction head, and facilitating the adjustment of the traction distance between the frame 1 and the traction head according to the use requirements of the flatbed semi-trailer, thereby providing a stable avoidance space for the flatbed semi-trailer transportation.

[0065] Please refer to Figure 3 and Figure 4 The traction assembly 6 further includes a locking rod 63, the top of the traction pin 62 is inserted into the connection box 61, a docking card hole 621 is provided on the traction pin 62, one end of the locking rod 63 passes through the connection box 61 and is inserted into the docking card hole 621, and the locking rod 63 is used to lock the traction pin 62 and install it on the connection box 61;

[0066] The intelligent flatbed traction device of the new energy semi-trailer also includes a second telescopic member 7, which is installed within the range of the installation mechanism 4, and the telescopic part of the second telescopic member 7 is fixedly connected to the locking rod 63, and the second telescopic member 7 is used to drive the locking rod 63 to adjust the telescopic movement.

[0067] In this embodiment, the traction pin 62 includes two usage states:

[0068] In the locked state, the locking rod 63 passes through the connection box 61 and is inserted into the docking card hole 621, the traction pin 62 is locked with the connection box 61, and the traction pin 62 and the connection box 61 are stably connected;

[0069] In the unlocked state, the locking rod 63 is out of the range of the docking card hole 621, the traction pin 62 and the connection box 61 are unlocked, and the traction pin 62 and the connection box 61 can be removed.

[0070] In this embodiment, an assembly port is provided at the bottom of the connecting box 61, and the top of the traction pin 62 is movably assembled on the bottom of the connecting box 61 through the assembly port. The bottom of the traction pin 62 extends to the bottom of the frame 1 through the adjusting slide hole 101, and is used for the traction connection between the flatbed semi-trailer and the traction head.

[0071] The second telescopic member 7 facilitates the telescopic adjustment of the locking rod 63. When the locking rod 63 is extended and adjusted, the locking rod 63 passes through the connection box 61 and is inserted into the docking card hole 621, so that the traction pin 62 is locked and installed on the connection box 61, thereby facilitating the locking and limiting of the traction pin 62 and the connection box 61 after installation.

[0072] When the locking rod 63 is contracted and adjusted, the locking rod 63 is pulled out of the range of the docking card hole 621, unlocking the traction pin 62 and the connecting box 61, thereby facilitating the separation of the traction pin 62 and the connecting box 61, so as to facilitate the rapid replacement of the traction pin 62 after it is worn and can no longer be used.

[0073] Please refer again Figure 2 The mounting mechanism 4 includes a fixed frame 41, two reinforcing slides 42 and a reinforcing cross frame 43. The fixed frame 41 is fixed on the vehicle frame 1. The two reinforcing slides 42 are distributed in parallel and fixed on the fixed frame 41. The reinforcing cross frame 43 is arranged perpendicular to the reinforcing slides 42 and fixed on the fixed frame 41. The bottom of the reinforcing cross frame 43 abuts against the top of the reinforcing slide 42.

[0074] The connection box 61 is slidably installed between the reinforcement slide 42 and the vehicle frame 1 .

[0075] The reinforced slide 42 cooperates with the frame 1 to provide a stable support and limiting effect for the connecting box 61, so that when the connecting box 61 and the traction pin 62 are connected and used, the pressure of the connecting box 61 on the first telescopic member 5 is reduced, so that the pressure is evenly applied to the fixed frame 41 and the frame 1 through the reinforced slide 42 and the reinforced cross frame 43, thereby avoiding local pressure overload of the connecting box 61 and causing damage to the adjustment structure.

[0076] The reinforcing slide 42 and the reinforcing cross frame 43 are added within the fixed frame 41 to provide load-bearing and pressure-bearing capabilities when the traction pin 62 is used on the connecting box 61, thereby increasing the stability of the adjustable traction pin 62.

[0077] In an optional implementation of the present embodiment, the bottom of the fixed frame 41 is fixed to the bottom of the inner wall of the frame 1; the top of the fixed frame 41 is fixed to the top of the inner wall of the frame 1, and the fixed frame 41 can transfer the force of the traction pin 62 to the frame 1, so that the connection of the traction structure is more stable.

[0078] Furthermore, the reinforcing slide 42 is in an L-structure, and the two reinforcing slides 42 are symmetrically arranged.

[0079] In this embodiment, the fixed frame 41, the reinforced slide 42 and the reinforced cross frame 43 are all reinforced steel structures; and the connection parts are all fully welded and fixed; the fixed frame 41 and the frame 1 are fully welded and fixed, which increases the stability of the connection structure of each part.

[0080] The L-shaped reinforcing slide 42 can provide edge limits for the stable telescopic adjustment of the connecting box 61, so that the stability of the contact between the connecting box 61 and the frame 1 and the reinforcing slide 42 can be maintained whether the connecting box 61 is being adjusted or under traction.

[0081] Please refer again Figure 3 The mounting mechanism 4 further includes a locking frame 44 , on which a plurality of locking holes 441 are formed. The locking holes 441 are distributed within the adjustment range of the locking rod 63 .

[0082] In this embodiment, the connection box 61 includes two usage modes:

[0083] In the limited mode, the locking rod 63 is inserted into the locking hole 441, and the connection box 61 cannot be telescopically adjusted by the first telescopic member 5, so as to increase the stability of the traction pin 62 when used in the locked state;

[0084] In the adjustment mode, the locking rod 63 is out of the range of the locking hole 441 , and the connection box 61 can be telescopically adjusted through the first telescopic member 5 , so that the work position can be adjusted when the traction pin 62 is locked.

[0085] In this embodiment, in the limiting mode, the locking rod 63 can continue to move toward the locking hole 441 .

[0086] The plurality of locking holes 441 are evenly distributed on the locking frame 44 , so that after the traction pin 62 is adjusted to different positions, the traction pin 62 can be stably locked at the corresponding position.

[0087] When the locking rod 63 is inserted into the locking hole 441, the locking rod 63 also locks the traction pin 62 on the connecting box 61, thereby increasing the stability of the traction pin 62 during traction connection and reducing the pressure on the first telescopic member 5; it is convenient to transmit the traction tension exerted on the traction pin 62 to the fixed frame 41 and the vehicle frame 1 through the connecting box 61, the locking rod 63 and the locking frame 44, thereby achieving stable traction of the flatbed semi-trailer.

[0088] Please refer to Figure 3 and Figure 5 The second telescopic member 7 includes a hydraulic cylinder 71, a synchronous frame 72, a transmission rod 73 and a synchronous sliding shaft 74. The fixed portion of the hydraulic cylinder 71 is fixed on the frame 1, the synchronous frame 72 is fixed on the telescopic portion of the hydraulic cylinder 71, and the two ends of the transmission rod 73 are respectively hinged to the synchronous frame 72 and the synchronous sliding shaft 74;

[0089] Two sliding holes 411 are provided on the fixed frame 41, the synchronous sliding shaft 74 passes through the sliding holes 411 and is slidably installed on the fixed frame 41, and the synchronous sliding shaft 74 passes through the locking rod 63 and is slidably connected; the locking frame 44, the transmission rod 73, the synchronous sliding shaft 74, the locking rod 63 and the sliding holes 411 are equal in number and are arranged one by one.

[0090] The adjustment principle of the locking lever 63 is as follows:

[0091] When it is necessary to unlock the traction pin 62 and the connection box 61, the hydraulic cylinder 71 is started to contract, and the hydraulic cylinder 71 drives the synchronous frame 72 to move downward. When the synchronous frame 72 moves downward, the transmission rod 73 pushes the synchronous sliding shaft 74 to move away from the connection box 61, and the synchronous sliding shaft 74 synchronously drives the locking rod 63 to move, so that the locking rod 63 is gradually withdrawn from the docking card hole 621 when moving, until the locking rod 63 is completely separated from the docking card hole 621, and the traction pin 62 and the connection box 61 are unlocked to facilitate the replacement between the traction pin 62 and the connection box 61;

[0092] When it is necessary to lock the replaced traction pin 62, first insert the traction pin 62 into the range of the connecting box 61, and maintain the docking card hole 621 aligned with the telescopic range of the locking rod 63; start the hydraulic cylinder 71 to extend, and the hydraulic cylinder 71 drives the synchronous frame 72 to move upward. When the synchronous frame 72 moves upward, the synchronous sliding shaft 74 is pulled toward the connecting box 61 through the transmission rod 73, and the synchronous sliding shaft 74 synchronously drives the locking rod 63 to move, so that the locking rod 63 is gradually inserted into the docking card hole 621 when moving, until the locking rod 63 is completely inserted into the docking card hole 621, and the traction pin 62 is locked with the connecting box 61, so as to facilitate the locking of the traction pin 62 after replacement and installation.

[0093] The locking rods 63 are arranged on both sides of the connecting box 61 to further increase the stability of the connecting box 61 and the traction pin 62 after installation and locking; at the same time, the hydraulic cylinder 71 is used to conveniently and synchronously drive the synchronous sliding shafts 74 on both sides to extend or contract, thereby facilitating the synchronous adjustment of the locking rods 63 on both sides.

[0094] In an optional implementation of this embodiment, two hydraulic cylinders 71 are provided, and the two hydraulic cylinders 71 are symmetrically distributed at the bottom of the synchronous frame 72 to stably drive the lifting and lowering adjustment of the synchronous frame 72 .

[0095] The working principle of the intelligent flatbed traction device for the new energy semi-trailer provided in this embodiment is as follows:

[0096] like Figure 5 and Figure 6 As shown in (a), it may be defined that in the initial state, the traction pin 62 is in a locked state, the connection box 61 is in a limited mode, and the locking rod 63 is inserted into the docking card hole 621 and the locking hole 441 at the same time;

[0097] Please refer to Figure 6 (a) to Figure 6 (b) and Figures 5 to 7(a) When the use position of the traction pin 62 needs to be adjusted, the hydraulic cylinder 71 is first started to extend, and the hydraulic cylinder 71 drives the synchronous frame 72 to move upward. The synchronous frame 72 pulls the synchronous sliding shaft 74 toward the direction of the connection box 61 through the transmission rod 73. When the synchronous sliding shaft 74 moves, it simultaneously drives the locking rod 63 to move. The locking rod 63 is pulled out of the locking hole 441 and the locking rod 63 is kept inserted into the docking card hole 621, so as to facilitate the adjustment of the use position of the traction pin 62;

[0098] During adjustment, the first telescopic member 5 is started to extend, and the first telescopic member 5 drives the connection box 61, the traction pin 62 and the locking rod 63 to move as a whole, so as to switch the use position of the traction pin 62. After switching, the locking rod 63 should be kept aligned with the corresponding locking hole 441 to provide support for the subsequent insertion of the locking rod 63 into the locking hole 441.

[0099] like Figure 6 (b) and Figure 7 As shown in (b), the traction pin 62 is in a locked state, the connection box 61 is in an adjustment mode, and the locking rod 63 is inserted into the docking card hole 621 and out of the range of the locking hole 441;

[0100] Please refer to Figure 6 (b) to Figure 6 (a) and Figure 7 (a) to Figure 5 When the adjusted connection box 61 needs to be locked, the hydraulic cylinder 71 is started to contract, and the hydraulic cylinder 71 drives the synchronous frame 72 to move downward. The synchronous frame 72 pushes the synchronous sliding shaft 74 to move away from the connection box 61 through the transmission rod 73. When the synchronous sliding shaft 74 moves, it simultaneously drives the locking rod 63 to move. The locking rod 63 is inserted into the locking hole 441, so that the connection box 61 is locked on the locking frame 44 through the locking rod 63. The locking rod 63 maintains the state of being inserted into the docking card hole 621, so that the traction pin 62 can use the locking limit after the position adjustment;

[0101] Please refer to Figure 6 (a) to Figure 6 (c) and Figures 5 to 7(b) When the traction pin 62 needs to be removed, the hydraulic cylinder 71 is started to contract, and the hydraulic cylinder 71 drives the synchronous frame 72 to move downward. The synchronous frame 72 pushes the synchronous sliding shaft 74 to move away from the connection box 61 through the transmission rod 73. When the synchronous sliding shaft 74 moves, it drives the locking rod 63 to move synchronously. The locking rod 63 continues to be inserted into the locking hole 441 and gradually leaves the range of the docking card hole 621 until the locking rod 63 completely leaves the range of the docking card hole 621, so as to facilitate the replacement of the traction pin 62;

[0102] like Figure 6 (c) and Figure 7 As shown in (b), the traction pin 62 is in an unlocked state, the connection box 61 is in a limited mode, and the locking rod 63 is inserted into the locking hole 441 and out of the range of the docking card hole 621.

[0103] Finally, the movement and adjustment requirements of the traction pin 62 are met, and the stability of the traction pin 62 during use can be increased. When the locking rod 63 is fully inserted into the locking hole 441, the traction pin 62 can also be unlocked, so that the replacement of the traction pin 62 in a fixed state is convenient.

[0104] Second embodiment.

[0108] The third telescopic member 9 is installed on the switching box 83, and the third telescopic member 9 is used to drive the adjustment box 86 to move and adjust.

[0109] In this embodiment, hydraulic oil is stored in the hydraulic tank 81 to provide support for the driving adjustment of the hydraulic pump 82 .

[0110] In this embodiment, one end of the regulating box 86 is open, and the opening faces the output end of the liquid inlet pipe 831 . The regulating box 86 maintains communication with the output end of the liquid inlet pipe 831 when the state is adjusted.

[0111] The regulating box 86 , the switching box 83 , the first partition plate 84 and the second partition plate 85 are slidably sealed.

[0112] In this embodiment, the adjustment box 86 includes two usage modes:

[0113] like Fig.11 or Fig.12 (a) shows a support liquid supply mode, wherein the adjustment box 86 is connected to the second through hole 850 through the docking hole 860, so as to provide support for the hydraulic supply inside the first liquid supply pipe 832, and the hydraulic pump 82 is used to drive the telescopic adjustment of the hydraulic support member 3 to provide hydraulic supply;

[0114] like Fig.12 As shown in (b), the liquid supply mode is adjusted, the adjustment box 86 is connected to the first through hole 840 through the docking hole 860, so as to provide support for the hydraulic supply inside the second liquid supply pipe 833; the hydraulic pump 82 is used to drive the telescopic adjustment of the first telescopic member 5 to provide hydraulic supply.

[0115] Finally, under the driving action of the hydraulic pump 82, it can be used for both the movement adjustment of the connection box 61 and the telescopic adjustment of the hydraulic support 3, thereby reducing the consumption of power drive.

[0116] In an optional implementation of the present embodiment, the third telescopic member 9 is an independent hydraulic telescopic cylinder, and the third telescopic member 9 is fixedly connected to the switching box 83 and the regulating box 86, and the regulating box 86 is independently adjusted and controlled by the hydraulic telescopic cylinder.

[0117] In another optional implementation of this embodiment, please refer to Figure 8 and Fig.10 The third telescopic member 9 is an L-shaped connecting member. A switching sliding hole 830 is provided on the switching box 83. The third telescopic member 9 passes through the switching sliding hole 830 and is fixedly connected to the synchronous sliding shaft 74 and the adjusting box 86.

[0118] The third telescopic member 9 connects the adjusting box 86 and the synchronous sliding shaft 74, so that the synchronous sliding shaft 74 can synchronously drive the adjusting box 86 to move when moving and adjusting, so as to synchronously realize the synchronous switching of the adjusting box 86 mode during the mode switching of the connecting box 61.

[0119] The synchronous sliding shaft 74 is connected to the adjustment box 86 through the third telescopic member 9, and the movement of the adjustment box 86 can be synchronously realized while the synchronous sliding shaft 74 moves and adjusts; when the synchronous sliding shaft 74 drives the connection box 61 to switch from the limit mode to the adjustment mode, the synchronous sliding shaft 74 synchronously drives the adjustment box 86 to switch from the support liquid supply mode to the adjustment liquid supply mode through the third telescopic member 9; when the synchronous sliding shaft 74 drives the connection box 61 to switch from the adjustment mode to the limit mode, the synchronous sliding shaft 74 synchronously drives the adjustment box 86 to switch from the adjustment liquid supply mode to the support liquid supply mode through the third telescopic member 9;

[0120] Finally, under the driving action of the hydraulic cylinder 71, the mode of the connection box 61 is switched, and the mode of the adjustment box 86 is switched synchronously.

[0121] The working principle of the intelligent flatbed traction device for the new energy semi-trailer provided in this embodiment is as follows:

[0122] like Fig.11 As shown, it may be defined that in the initial state, the docking hole 860 on the adjustment box 86 is connected with the second through hole 850, the first through hole 840 is in a closed state, and the hydraulic pump 82 provides hydraulic supply to the first liquid supply pipe 832 through the adjustment box 86, so that the hydraulic support member 3 is driven to be telescopically adjusted through the hydraulic pump 82;

[0123] Please refer to Figure 11 to Figure 12 (a), when the connection box 61 is switched from the limiting mode to the adjusting mode, the synchronous sliding shaft 74 also synchronously drives the third telescopic member 9 to move, and the third telescopic member 9 drives the adjusting box 86 to move, so that the docking hole 860 on the adjusting box 86 is separated from the second through hole 850, and the docking hole 860 is aligned with and connected to the first through hole 840, so that the adjusting box 86 is switched from the supporting liquid supply mode to the adjusting liquid supply mode;

[0124] In the hydraulic supply adjustment mode, the hydraulic pump 82 is used to drive the first telescopic member 5 to adjust the telescopic movement;

[0125] like Fig.12 As shown in (a), the docking hole 860 on the adjustment box 86 is connected to the first through hole 840, and the second through hole 850 is in a closed state. The hydraulic pump 82 provides hydraulic supply to the second liquid supply pipe 833 through the adjustment box 86, thereby driving the first telescopic member 5 to telescope and adjust through the hydraulic pump 82;

[0126] Please refer to Figure 11 to Figure 12 (b) When the traction pin 62 is switched from the locked state to the unlocked state, the synchronous sliding shaft 74 also synchronously drives the third telescopic member 9 to move, and the third telescopic member 9 drives the adjustment box 86 to move, so that the docking hole 860 on the adjustment box 86 maintains communication with the second through hole 850, and the first through hole 840 is kept closed, so that the hydraulic pump 82 drives the hydraulic support member 3 to adjust the telescopic movement;

[0127] Finally, under the action of the hydraulic cylinder 71, while driving the mode switching of the connection box 61, the use mode of the adjustment box 86 can also be switched synchronously; so that under the driving action of the hydraulic pump 82, it can be used for adjusting the position of the connection box 61 and also for the telescopic adjustment of the hydraulic support 3.
