The partition 11 completely divides the cylinder 3 into two chambers, and the gap distance between the partition 11 and the limiting rod 2 and the screw rod 4 is a conventional reserved point as long as the limiting rod 2 and the screw rod 4 are not directly contacted with the partition.
The bottom end of the screw rod 4 is provided with a screw rod shaft 41, the screw rod shaft 41 and the screw rod 4 are coaxial and integrated, the screw rod shaft 41 is inserted into the transmission box 15 from the side wall of one side of the transmission box 15, the transmission box 15 is a relatively closed space, in order to be convenient to process and install, a box body is generally processed firstly, an upper cover is covered on the box body, and a sealed space is formed through the matching of the upper cover and the box body. The two ends of the screw shaft 41 are connected with the upper wall and the lower wall of the transmission case 15 through screw bearings 17, and the two ends of the screw shaft 41 are connected with the two screw bearings 17 on the upper wall and the lower wall of the transmission case 15, so that the screw 4 and the screw shaft 41 can be ensured to rotate on the transmission case 15. The screw gear 16 is installed in the middle of the screw shaft 41 through a fixed pin, the screw gear 16 is connected with the driving gear 19 through the toothed belt 31, the toothed belt 31 is a belt with teeth, the teeth on the toothed belt 31 are meshed with the teeth of the screw gear 16 and the driving gear 19, and through the structure, the driving gear 19 and the screw gear 16 can be ensured to be meshed through the toothed belt 31 with teeth to complete synchronous rotation. The driving gear 19 is mounted on the middle shaft 28 through a fixing pin, two ends of the middle shaft 28 are mounted on the upper wall and the lower wall of the transmission case 15 through the middle shaft bearing 30, the connection mode of the two ends of the middle shaft 28 and the upper wall and the lower wall of the transmission case 15 is the same as the connection mode of the screw shaft 41 and the transmission case 15, but two ends of the middle shaft 28 can be the same as or connected with the outside of the transmission case 15. The motor 5 is fixedly arranged on a box body outside the transmission box 15, a motor shaft 18 of the motor 5 is fixedly connected with one end of a middle shaft 28, the other end of the middle shaft 28 is provided with a manual operation hole 29, the manual operation hole 29 is arranged for standby operation, and when the motor 5 fails, manual operation can be carried out through a tool matched with the hole. A guide master gear 27 is mounted on the central shaft 28 through a fixing pin, the guide master gear 27 is engaged with the guide slave gear 26, the guide slave gear 26 is fixedly mounted on the shaft on one side of the guide shaft 20, and the guide shaft 20 is threaded except for one end shaft portion, that is, the guide shaft 20 is threaded except for the portion connected with the guide slave gear 26, and the rest of the guide shaft 20 is threaded. The bottom end of the positioning sliding block 22 is sleeved on the guide shaft 20, and an internal thread matched with the thread on the guide shaft 20 is arranged in the sleeve opening, so that the positioning sliding block 22 can move up and down under the driving of the thread when the guide shaft 20 rotates. The inner wall of the transmission case 15 is fixedly provided with a guide rod 24, the middle part of the positioning slide block 22 is sleeved on the guide rod 24, and the positioning slide block 22 can be ensured to keep moving on a straight line through the guide shaft 20 and the guide rod 24. An upper limit stop 23 and a lower limit stop 25 with sensors are respectively and fixedly arranged on the upper side wall and the lower side wall of the transmission case 15 corresponding to the upper end of the positioning slide block 22; the upper limit stopper 23 and the lower limit stopper 25 with sensors adopt a conventional signal receiving function, and the operation of the motor 5 is stopped immediately no matter which stopper the positioning slider 22 touches.
A fixed rod 7 is arranged on the side wall of the other side of the transmission case 15 corresponding to the screw rod 4 through a fastening bolt 6, and a bottom beam end shaft sleeve 8 is arranged at the end part of the fixed rod 7. The whole mechanism is only used for fixedly mounting the bottom end of the cab, the fixed rod 7 and the screw rod 4 must be guaranteed to be in the same center, the fixed rod 7 is tightly mounted on the transmission case 15 through the fastening bolt 6, and is sleeved on a frame bottom beam at the bottom end of the cab in a shaft mode through a bottom beam end shaft sleeve 8.
The operation process is as follows:
the cab rises:
the motor 5 rotates positively to drive the middle shaft 28 through the motor shaft 18 and simultaneously drive the driving gear 19 to rotate positively, and then drive the screw shaft 41 to rotate synchronously through the toothed belt 31, because the screw shaft 41 and the screw 4 are integrated, the screw 4 also rotates synchronously, so that the screw 4 rotates positively, the gear sleeve 13 ascends upwards along the screw 4 under the action of the screw thread, and simultaneously the cylinder 3 fixed integrally with the screw ascends synchronously, in the ascending process, the partition plate gradually contacts with the bottom of the rod 2, and after the partition plate completely contacts with the bottom of the rod 2, the rod 2 is pushed to ascend upwards, so that the cab is lifted through the rod 2, and because the cab is overturned to one side to lift in the lifting process, the side shifting is completed through the rotation of the cab end shaft sleeve 1.
In the rotation process of the middle shaft, the positioning slide block 22 is driven to move upwards, and when the positioning slide block 22 contacts the upper limiting stop 23, the motor 5 stops working, and the cab is completely lifted.
Descending the cab: (when the motor rotates in the reverse direction, the lowering process is completed).
Manual operation:
when the electric pump is not operated, manual operation is possible. The manual operation hole 29 can be used, and it is generally convenient to arrange that the manual operation hole 29 is in a hexagon socket head and then the lifting and lowering operation is performed by a hexagon wrench, and since the manual operation hole 29 is formed on the middle shaft 28, the lifting or lowering operation process is the same as the operation process of the motor.
