[0028] like Figure 1-10 As shown, the utility model provides a device for installing a rotary vertical shaft 14 of an electric shovel, comprising a base plate 1, an electric screw rod 2, a hydraulic oil tank 3, a central hydraulic oil cylinder 4 and three pallet hydraulic oil cylinders 5 are arranged on the upper surface of the base plate 1, the central hydraulic oil cylinder 4 is arranged at the center of the base plate 1, the three pallet hydraulic oil cylinders 5 are arranged in an arc array on the outside of the central hydraulic oil cylinder 4, and a rotary vertical shaft flange pallet 6 is arranged on the top of the pallet hydraulic oil cylinder 5;

[0029] A transport tank 7 and a supporting hydraulic cylinder 8 are provided at the bottom of the base plate 1 , the transport tank 7 is welded to the four corners of the base plate 1 , and a lifting eye base 9 is provided between the supporting hydraulic cylinder 8 and the base plate 1 .

[0030] In addition, the transport tank 7 is used to bear the weight of the bottom plate 1 and other parts and to move the bottom plate 1 horizontally. The transport tank 7 is welded to the lower plane of the bottom plate 1, and the bottom plate 1 is moved horizontally to the left and right through the extension and contraction of the electric lead screw. This drives the secondary lifting device to move horizontally, which is convenient for adjusting the horizontal position of the vertical shaft and the shaft hole.

[0031] Furthermore, in this embodiment, the bottom end of the electric screw 2 is welded to the bottom plate 1, and the top end of the electric screw 2 is provided with a screw fixing base 12, which is used to move the tank car laterally, and finally enables the shaft to move laterally, and is used to move the bottom plate 1 laterally, so that the vertical shaft can move laterally. The two ends of the electric screw are fixed to the bottom plate 1 and the frame by welding.

[0032] In this embodiment, a central hydraulic cylinder pallet 11 is provided at the top of the central hydraulic cylinder 4, and the central hydraulic cylinder 4 is bolted to the base plate 1. The central hydraulic cylinder 4 is arranged at the center position of the pallet hydraulic cylinder 5 and is fixed to the base plate 1 by 6 M16 bolts. The main function is to cooperate with the pallet hydraulic cylinder 5 to realize the jacking of the shaft, especially the matching stage of the bearing of the vertical shaft and the mounting hole, which requires a larger jacking force. At this time, the central hydraulic cylinder 4 plays an important role. According to the installation experience, the central hydraulic cylinder 4 selects the second-level jacking, and the bearing capacity of the central hydraulic cylinder 4 is 20 tons.

[0033] In this embodiment, a foot 10 is provided at the bottom end of the supporting hydraulic cylinder 8, a pin is provided between the top end of the supporting hydraulic cylinder 8 and the lifting ear base 9, and the supporting hydraulic cylinder 8 is rotatably connected by the pin. The supporting hydraulic cylinder 8 is fixed under the floor by 6 M16 bolts. When the vertical shaft is lifted, the supporting hydraulic cylinder 8 changes from a horizontal state to a vertical position and extends out, and forms a solid supporting effect after contacting the ground. The horizontal to vertical state is achieved by the forward and reverse rotation of the electric winch. The bearing capacity of the supporting hydraulic cylinder 8 is 30 tons.

[0034] In this embodiment, a swivel vertical shaft fixing hole 13 is opened on the surface of the swivel vertical shaft flange pallet 6, and the pallet is hinged with three pallet hydraulic cylinders 5. Its main function is to lift the swivel vertical shaft 14. The connecting holes provided on the pallet facilitate the connection and lifting of the vertical shaft and the pallet.

[0035] In this embodiment, the rotary vertical shaft flange pallet 6 is hinged to the pallet hydraulic cylinder 5. The three pallet hydraulic cylinders 5 are equidistantly arranged at the bottom of the rotary vertical shaft flange pallet 6 and symmetrically arranged in an equilateral triangle. Displacement sensors are provided inside the three pallet hydraulic cylinders 5.

[0036] In addition, the bearing capacity of a single cylinder is 8 tons. Each cylinder is fixed to the base plate 1 by the lower flange with 4 M14 bolts. The slewing vertical shaft 14 is placed on the slewing vertical shaft flange tray 6. The pallet hydraulic cylinder 5 can achieve synchronous lifting and single action through displacement sensor feedback and program control. The horizontal angle of the pallet can be changed through single action, and then the angle of the vertical shaft can be adjusted. Its main function is to realize the adjustment of the pallet angle and the rotation of the gear on the shaft and the lifting function before the vertical shaft bearing enters the hole (before the effort stage). The vertical shaft is fixed by the slewing vertical shaft flange tray 6 to prevent the vertical shaft from tipping over.

[0037] The specific workflow is as follows: the first step is to place the rotary vertical shaft 14 on the device using a crane and connect it to the rotary vertical shaft flange tray 6 with bolts;

[0038] The second step is to control the device to move forward, backward, turn left and right through the remote control. Visually check that the forward direction axis is aligned with the axis hole and the device stops. The remote control operation method is to turn the left switch to the left position, the left second switch to the left position, the right second switch to the middle position, and the right first switch to the left position. The operation is as follows:

[0039] (1) The device moves forward: joy1_u and joy2_u are pushed upward at the same time;

[0040] (2) Device moves backward: joy1_u and joy2_u are pushed upward at the same time;

[0041] (3) The device turns left: push joy1_u upward;

[0042] (4) Turn the device right: push joy2_u upward;

[0043] The third step is to extend the bottom leveling legs. After the equipment reaches the specified position, extend the four legs at the bottom of the equipment. By placing an angle sensor on the edge of the large platform of the electric shovel and observing, adjust the four legs so that the angle sensor value is within the range of plus or minus 1°, and then stop adjusting to ensure the horizontality of the equipment. The remote control operation method is: turn the left switch to the left position, the left second switch to the right position, the right second switch to the right position, and the right switch to the left position. Specifically:

[0044] (1) 1# outrigger extends: press button 1;

[0045] (2) 2# outrigger extends: press button 2;

[0046] (3) 3# outrigger extends: press button 3;

[0047] (4) 4# outrigger extends: press button 4;

[0048] Step 4. Raise the large platform. After the outriggers are adjusted, use the remote control to raise the large platform so that the upper plane of the large platform is 2-2.2 meters from the ground. At this time, the shaft will enter the shaft hole. Visually check whether the shaft is in the center of the shaft hole. If the shaft is not in the center, stop lifting the large platform and proceed to the fifth step to adjust the shaft to the center of the shaft hole. The remote control operation method is: turn the left switch to the right position, the left second switch to the middle position, the right second switch to the middle position, and the right switch to the left position. The operation is as follows:

[0049] (1) The big platform rises: joy1_u pushes upward;

[0050] The fifth step is to adjust the tank to achieve lateral movement. Press the lateral left shift button, and the electric lead screw drives the tank to move left, so that the axis moves left. Similarly, press the lateral right shift button, and the electric lead screw drives the tank to move right, so that the axis moves right. You can adjust according to the actual situation.

[0051] Step 6: After the support hydraulic cylinder 8 is lowered and the shaft is located in the center of the shaft hole, the support hydraulic cylinder 8 is lowered from the horizontal position to the vertical position by pressing the support hydraulic cylinder 8 lowering button, and the button is released;

[0052] Step 7: The supporting hydraulic cylinder 8 is lowered. Press the lowering button of the supporting hydraulic cylinder 8, and the supporting hydraulic cylinder 8 extends and lowers to the ground, and then releases the button;

[0053] Step 8. The three-cylinder platform rises to a position synchronously. The three cylinders are lifted synchronously by remote control. The whole platform rises to a position 5 cm before the large gear of the axis engages. The vertical axis gear is manually rotated at an angle and the platform continues to rise to engage the two gears. The left switch of the remote control is turned to the right position, the left switch is turned to the middle position, the right switch is turned to the left position, and the right switch is turned to the left position. The operation is as follows:

[0054] (1) The secondary platform rises: joy2_u pushes upward;

[0055] Step 9. Use three oil cylinders to adjust the vertical axis angle. Visually check the parallelism between the axis and the axis hole. If they are not parallel, move the corresponding oil cylinder among the three oil cylinders until they are parallel. Stop the adjustment. Move the left switch of the remote control to the right position, the left second switch to the middle position, the right second switch to the middle position, and the right first switch to the right position. The operation is as follows:

[0056] (1) 1# oil cylinder extends: press button 1 + joy2_u to push upward;

[0057] (2) 2# oil cylinder extends: press button 2 + joy2_u to push upward;

[0058] (3) 3# oil cylinder extends: press button 3 + joy2_u to push upward;

[0059] Step 10: The center hydraulic cylinder 4 rises, removes the two fixing screws, and uses the remote control to raise the center hydraulic cylinder 4 to hold the vertical shaft. The vertical shaft rises one position. At this time, it is necessary to manually rotate the reducer to make the vertical shaft fine spline enter the reducer. The center hydraulic cylinder 4 continues to lift until the rotary vertical shaft 14 is installed in place, and then install the fixing screws of the vertical shaft flange. At this point, the shaft is installed. The remote control is turned from the left switch to the right position, the left second switch to the middle position, the right second switch to the middle position, and the right switch to the right position. The operation is as follows:

[0060] (1) Main push cylinder extends: Press button 4 + joy2_u to push upward.

[0061] In addition, the three-cylinder platform rises synchronously to a position and the equipment reset process is as follows:

[0062] In the first step, the center hydraulic cylinder 4 descends. When the vertical shaft is pushed to the predetermined position, the center hydraulic cylinder 4 descends to ensure the stability and fixation of the vertical shaft. The remote controller switches the left switch to the right position, the left switch to the middle position, the right switch to the middle position, and the right switch to the right position. The operation is as follows:

[0063] (1) Retract the main push cylinder: press button 4 + joy2_u and push downward;

[0064] The second step is to retract the auxiliary platform support hydraulic cylinder 8. After the central hydraulic cylinder 4 is lowered into place, the support hydraulic cylinder 8 retraction button is pressed to retract the auxiliary platform support hydraulic cylinder 8 into place.

[0065] The third step is to retract the auxiliary platform support hydraulic cylinder 8. After the auxiliary platform support hydraulic cylinder 8 is retracted, press the support hydraulic cylinder 8 retraction button to adjust the support hydraulic cylinder 8 below it to the level;

[0066] Step 4: The three oil cylinders are lowered as a whole. The first left switch of the remote control is turned to the right position, the second left switch is turned to the middle position, the second right switch is turned to the left position, and the first right switch is turned to the left position. The operation is as follows:

[0067] (1) The secondary platform descends: joy2_u pushes downward;

[0068] Step 5: The main platform descends as a whole. Move the left switch of the remote control to the right, the left switch to the middle, the right switch to the middle, and the right switch to the left. The operation is as follows:

[0069] (1) The large platform descends: joy1_u pushes downward;

[0070] Step 6. Retract the bottom legs, turn the left switch to the left, turn the left switch to the right, turn the right switch to the right, and turn the right switch to the right. The operation is as follows:

[0071] (1) 1# outrigger retracts: press button 1;

[0072] (2) Retract the 2# outrigger: press button 2;

[0073] (3) 3# outrigger retract: press button 3;

[0074] (4) 4# outrigger retracts: press button 4;

[0075] Step 7: The equipment walks out of the working area. Finally, the equipment will leave the working area safely and accurately through its walking mechanism to complete the entire work process. The left switch of the remote control is turned to the left position, the left switch is turned to the left position, the right switch is turned to the middle position, and the right switch is turned to the left position. The operation is as follows:

[0076] (1) The device moves forward: joy1_u and joy2_u are pushed upward at the same time;

[0077] (2) Device moves backward: joy1_u and joy2_u are pushed upward at the same time;

[0078] (3) The device turns left: push joy1_u upward;

[0079] (4) Turn the device right: push joy2_u upward.
