[0029] Please refer to Figure 1-7 , in the embodiment of the present invention, a cab transverse movement and lifting system includes a vehicle body 1 and a cab 2 provided on the vehicle body 1. The cab 2 is transversely moved and liftedly connected to the vehicle body 1 through a transverse movement and lifting mechanism.

[0030] The transverse movement part 3 includes a cab bracket 31. The cab 2 is located on the cab bracket 31. The cab bracket 31 is horizontally slidably connected to the vehicle body 1 through a first slideway 32. There are two first slideways 32, and the two first slideways 32 are arranged in parallel. Both sides of the cab bracket 31 are slidably connected to the vehicle body 1 through the two first slideways 32. A driving part for pushing the cab bracket 31 to horizontally move in the first slideway 32 is provided on the first slideway 32. The driving part includes a transverse movement oil cylinder 33 fixedly connected to the first slideway 32. The front end of the piston of the transverse movement oil cylinder 33 is connected with a hook 38 through a hook connection seat 37. The hook 38 includes a vertical plate rotatably connected to the hook connection seat 37 and a horizontal plate located at the upper end of the vertical plate for limiting. Columns 35 arranged horizontally and cooperating with the hook 38 are provided on both sides of the cab bracket 31.

[0031] The vertical lifting part 4 includes a support frame 41 that is slidably connected to the vehicle body 1 up and down. The support frame 41 is located outside the first slideway 32. Second slideways 45 are provided on both sides of the support frame 41. A latch 46 is provided at one end of the second slideway 45 away from the first slideway 32. A vertical track 42 is fixedly arranged on the vehicle body 1. The support frame 41 is slidably connected to the vertical track 42. A vertical moving oil cylinder 43 for driving the support frame 41 to slide up and down is provided on one side of the vertical track 42. A first wire rope sensor 34 is provided on the transverse moving oil cylinder 33. A second wire rope sensor 44 is provided on the vertical moving oil cylinder 43. A first position sensor 36 is provided on the cab bracket 31. A second position sensor 47 is provided on the support frame 41. The cab bracket 31 is movably connected to the support frame 41.

[0032] A controller and a control panel are provided inside the cab 2. The controller is in signal communication with the first wire rope sensor 34, the second wire rope sensor 44, the first position sensor 36, and the second position sensor 47. A movement enabling switch is provided on the control panel.

[0033] A cab transverse movement and lifting control method includes the following steps:

[0034] Step 1: Input a control movement instruction through the cab control panel. The movement instruction includes a working state and a transportation state.

[0035] Step 2: Detect the current position. If the cab is in the working position and the movement instruction is the transportation state, then execute Step 3; if the cab is in the transportation position and the movement instruction is the working state, then execute Step 4.

[0036] Step 3: Move the cab bracket 31 to the support frame 41 through the transverse movement part 3, and move the support frame 41 and the cab 2 on the support frame 41 to the transportation position through the vertical movement part 4.

[0037] Step 3 includes the following steps:

[0038] Step 3.1: Close the cab movement enabling switch to prepare for cab movement.

[0039] Step 3.2: Lift the support frame: The vertical moving oil cylinder 43 starts and pushes the support frame 41 to move upward until the second slideway 45 on the support frame 41 is flush with the first slideway 32 on the vehicle body 1. During this process, the positions of the support frame 41 and the second slideway 45 can be detected in real time through the second wire rope sensor 44 and the second position sensor 47 to ensure that the second slideway 35 is flush with the first slideway 32 when stopping the lifting.

[0040] Step 3.3, Cab Translation: The piston of the transverse movement oil cylinder 33 extends, pushing the cab bracket 31 to move from the first slideway 32 to the second slideway 45 until the cab bracket 31 completely moves onto the second slideway 45 and is fixed to the second slideway 45 by the latch 46. During this process, the position of the cab bracket 31 and the cab 2 can be detected and feedback through the first wire rope sensor 34 and the first position sensor 36 to ensure the accuracy of the horizontal movement position;

[0041] Step 3.4, Transverse Movement Cylinder Disengagement: The piston of the vertical movement oil cylinder 43 contracts, driving the support frame 41 to move downward on the vertical track 42, driving the cab 2 to descend through the support frame 41. At the same time, the position of the cab 2 is judged by the second position sensor 47 and the second wire rope sensor 44 until the columns 35 on both sides of the cab bracket 31 are disengaged from the hooks 38 at the front end of the transverse movement oil cylinder 33. In this embodiment, the hook 38 includes a vertical plate and a horizontal plate. Therefore, when the column 35 moves downward relative to the hook 38, the column 35 can be easily disengaged from the hook 38;

[0042] Step 3.5, Transverse Movement Cylinder Reset: The piston of the transverse movement oil cylinder 33 extends to complete the reset;

[0043] Step 3.6, Cab Descent: The piston of the vertical movement oil cylinder 43 contracts, driving the support frame 41 to move downward on the vertical track 42, driving the cab 2 to descend through the support frame 41. At the same time, the position of the cab 2 is judged by the second position sensor 47 and the second wire rope sensor 44 until the cab 2 moves to the transportation position.

[0044] Step 4, Move the cab 4 from the transportation position to a position parallel to the transverse movement part 3 through the vertical movement part 4, and then horizontally move the cab 2 to the working position through the transverse movement part 3;

[0045] Step 4 includes the following steps:

[0046] Step 4.1, Close the cab movement enable switch to prepare for cab movement;

[0047] Step 4.2, Cab Lifting: The piston of the vertical movement oil cylinder 43 extends to drive the support frame 41 to move upward. At the same time, the position of the second slideway 45 is judged by the second wire rope sensor 44 and the second position sensor 47 until the position of the second slideway 45 is flush with the position of the first slideway 32:

[0048] Step 4.3. The transverse movement oil cylinder 33 extends: The piston of the transverse movement oil cylinder 33 extends, pushing the hook 38 to move horizontally until the hook 38 is hooked onto the column 35. In this embodiment, since the vertical plate of the hook 38 is rotatably connected to the hook connecting seat 37, when the vertical plate of the hook 38 contacts the column 35, under the action of the horizontal thrust, the hook 38 rotates until the column 35 moves between the vertical plate of the hook 38 and the oil cylinder piston, and then under the action of the limiting horizontal plate, the hook 38 rotates reversely and resets, clamping the column inside the hook. When the piston of the transverse movement oil cylinder 33 retracts, the vertical plate of the hook 38 acts on the column 35. Due to the action of the limiting horizontal plate, the vertical plate will not continue to rotate, and thus the column 35 can be towed and moved in the direction close to the transverse movement oil cylinder 33;

[0049] Step 4.4. The cab moves horizontally: The piston of the transverse movement oil cylinder 33 retracts, driving the cab bracket 31 to move from the second slideway 45 to the first slideway 32. At the same time, the position of the cab bracket 31 is detected by the first position sensor 36 and the first wire rope sensor 34 until the cab bracket 31 completely enters the first slideway 32 and moves to the working position;

[0050] Step 4.5. The support frame descends: The piston of the vertical movement oil cylinder 43 retracts and drives the support frame 41 to descend and reset.
