[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] See also Figure 1-7 The present embodiment provides an adaptive adjustment device for the position of an operating rod of an engineering vehicle, comprising a seat 1, an operating rod 2 being arranged on the seat 1, and a buffer plate 11 being slidably arranged in the seat 1, and a buffer spring 12 being arranged at the bottom of the buffer plate 11; an adjustment component, the adjustment component comprising a rotating member and an unlocking member, after the buffer plate 11 moves downward, the rotating member is first driven to rotate to unlock the unlocking member, and then the operating rod 2 is driven to move by the unlocking member so that the operating rod 2 slides on the seat 1; a locking member is also included, when the operating rod 2 is adjusted, the shaking of the operating rod 2 is locked, and the buffer is made to slide on the seat 1 by the operator sitting on the seat 1. The downward movement of the plate 11 compresses the buffer spring 12, and the downward movement of the buffer plate 11 drives the rotating assembly to rotate, thereby unlocking the guide plate 32 through the unlocking member, and at the same time, the locking member locks the swing direction of the operating rod 2, and then the operating rod 2 is moved to a suitable position by the sliding rod 36 according to the operator's arm length, and then the guide plate 32 is locked by the unlocking member to achieve adaptive adjustment of the operating rod 2. When working, the locking member first locks the operating rod 2 and adjusts the operating rod 2 before unlocking it. When not working, the operating rod 2 is automatically locked. According to the working status of the engineering vehicle, the two modes are automatically switched to ensure the safety of the engineering vehicle.

[0022] In an embodiment further provided by the present invention, the unlocking member includes a fixed plate 31 fixed on the seat 1, a guide plate 32 is slidably arranged in the fixed plate 31, the operating rod 2 is arranged on the guide plate 32, a clamping block 33 is slidably arranged in the guide plate 32, a plurality of clamping grooves 34 are opened in the fixed plate 31, the clamping block 33 is slidably arranged in any of the clamping grooves 34, and a clamping spring 39 is fixedly connected to the clamping block 33.

[0023] Furthermore, the unlocking member further comprises a plurality of sliding rods 36 slidably disposed in the fixing plate 31, the top end of each of the sliding rods 36 is fixedly connected with a push plate 35, each of the push plates 35 is slidably disposed in each of the clamping grooves 34, and a damper is disposed between the sliding rods 36 and the fixing plate 31. After the sliding rods 36 push the push plates 35 upward, the speed at which the sliding rods 36 move downward is slowed down, thereby slowing down the elastic force of the clamping springs 39 pushing the clamping block 33 into the clamping groove 34, thereby increasing the adjustment time and facilitating the operator to make accurate adjustments. The fixing plate 31 further includes a connecting plate 37 , which is fixedly connected to each of the sliding rods 36 , and a connecting rod 38 is fixedly connected to the bottom of the connecting plate 37 , and the connecting rod 38 passes through the fixing plate 31 .

[0024] In an embodiment further provided by the present invention, the rotating member includes a rotating rod 41 that rotates and is inside the seat 1, one end of the rotating rod 41 extends outside the seat 1 and is movably in contact with the connecting rod 38, the bottom end of the buffer plate 11 is fixedly connected to a movable plate 42, a driving plate 43 is slidably arranged inside the movable plate 42, and the driving plate 43 is movably in contact with the other end of the rotating rod 41.

[0025] Furthermore, the rotating member further comprises a wedge plate 45 fixed to the inner wall of the seat 1, the wedge plate 45 is slidably disposed in the driving plate 43, the driving plate 43 is fixedly connected with an abutment spring 44, and a guide hole 46 is provided on the driving plate 43, and one side of the wedge plate 45 is wedge-shaped (such as Figure 5 As shown in the figure, when the driving plate 43 moves downward, the driving plate 43 slides on the surface of the wedge plate 45, so that the driving plate 43 drives the rotating rod 41 to rotate while moving into the movable plate 42, until the rotating rod 41 rotates to the lowest point and the driving rod 55 moves out of the rotating rod 41.

[0026] In the embodiment provided by the present invention, the locking member includes two support plates 51 slidably arranged in the guide plate 32, each of the support plates 51 extends to the outside of the guide plate 32 and is rotatably connected with the locking plate 52, and two locking grooves 54 adapted to the locking plates 52 are opened on the outside of the operating rod 2, and the two support plates 51 are fixedly connected by the same driving rod 55. When the clamping block 33 drives the support plate 51 to move, it drives the locking plate 52 to lock the locking groove 54. This is to adjust the position of the operating rod 2 so that the operating rod 2 is locked with the guide plate 32 to avoid swinging the operating mechanical arm when the operating rod 2 moves forward and backward. When the buffer plate 11 drives the support plate 51 to move and drives the locking plate 52 to lock the operating rod 2, it is to prevent the mechanical arm from moving due to accidental touching of the operating rod 2 when the engineering vehicle is not in use, thereby increasing safety.

[0027] Specifically, two fixing rods 53 are fixedly connected to the guide plate 32, and each of the locking plates 52 is respectively sleeved outside the fixing rods 53. Any of the support plates 51 slides and extends into the clamping block 33. A limiting hole is provided on the locking plate 52, and the fixing rod 53 is arranged in the limiting hole. When the support plate 51 pushes the locking plate 52 to move upward, the locking plate 52 will slide and rotate on the fixing rod 53, so that the locking plate 52 rotates into the locking groove 54, thereby locking the operating rod 2.

[0028] In a solution further provided by the present invention, a protective sleeve 21 is disposed on the outer cover of the operating rod 2 , and the protective sleeve 21 is fixedly connected to the guide plate 32 .

[0029] The present invention further includes a control member. After the pressure of the buffer plate 11 is released, the control member drives the locking member to move to lock the operating rod 2. The control member includes a limit ring 61 rotatably arranged outside the movable plate 42. A telescopic rod 62 is fixedly connected to the outside of the limit ring 61. The end of the telescopic rod 62 is rotatably connected to an abutment plate 63. The abutment plate 63 extends into the guide plate 32 and is in active contact with the drive rod 55.

[0030] In the present invention, the telescopic rod 62 extends into the fixed plate 31 and rotates in the fixed plate 31, the abutment plate 63 is slidably arranged in the guide plate 32, the abutment plate 63 rotates left and right on the telescopic rod 62, and the limit ring 61 is only connected in rotation outside the movable plate 42. When the buffer plate 11 drives the movable plate 42 to move up and down, the limit ring 61 is driven to move up and down synchronously, so that the telescopic rod 62 drives the abutment plate 63 to move up and down, so that the abutment plate 63 can push the driving rod 55 to move or move away, and when the guide plate 32 slides in the fixed plate 31, the abutment plate 63 moves synchronously, so that the telescopic rod 62 and the abutment plate 63 rotate, driving the limit ring 61 to rotate in the movable plate 42.

[0031] When in use, the operator sits on the seat 1 and pushes the buffer plate 11 downward by gravity, and at the same time drives the buffer spring 12 to be compressed. The downward movement of the buffer plate 11 drives the moving plate 42 to move, so that the driving plate 43 and the limiting ring 61 move synchronously. When the driving plate 43 moves, the driving plate 43 moves up and down on the wedge plate 45. When the guide hole 46 slides on the wedge plate 45, the driving plate 43 is pushed to slide into the moving plate 42, so that the driving plate 43 moves downward and drives the rotating rod 41 to rotate and move away from the rotating rod 41. When the limit ring 61 moves downward, the telescopic rod 62 is driven to move, so that the abutment plate 63 moves downward synchronously and moves out of the driving rod 55. The gravity of the driving rod 55 drives the two support plates 51 to move downward, so that the locking plate 52 rotates on the fixing rod 53, so that the locking plate 52 moves out of the locking groove 54, and the operating rod 2 is unlocked; When the rotating rod 41 rotates, the connecting rod 38 is pushed upward, so that the connecting plate 37 moves synchronously, so that the sliding rod 36 pushes the push plate 35 upward, thereby pushing the clamping block 33 out of the clamping groove 34, so that the clamping spring 39 is compressed; When the clamping block 33 moves upward, the support plate 51 is pushed to move synchronously, thereby pushing the locking plate 52 to rotate on the fixing rod 53, so that the locking plate 52 rotates into the locking groove 54 to lock the operating rod 2. Then the operator pushes the operating rod 2 to move forward and backward, driving the guide plate 32 to slide in the fixing plate 31, so as to perform adaptive adjustment according to personal habits. After the adjustment is completed, according to the gravity of the connecting plate 37, the push plate 35 moves down into the fixing plate 31, and then the elastic force of the clamping spring 39 is released, so that the clamping block 33 is clamped into the corresponding clamping groove 34, so as to adjust the position of the operating rod 2. When the guide plate 32 slides in the fixed plate 31, the abutment plate 63 moves synchronously, causing the telescopic rod 62 to rotate, thereby causing the limit ring 61 to rotate outside the movable plate 42. When the operation of the engineering vehicle is stopped, the operator stands up and leaves the operating room, and pushes the buffer plate 11 upward through the buffer spring 12, thereby driving the drive plate 43 to reset, and driving the limit ring 61 to move upward, thereby driving the abutment plate 63 upward through the telescopic rod 62, pushing the drive rod 55 to move synchronously, and driving the support plate 51 to move upward, so that the locking plate 52 moves into the locking groove 54 to lock the operating rod 2. When the engineering vehicle is not in use, the operating rod 2 is locked to avoid accidental touch.
