Referring to fig. 1, 2 and 9, the elevation assembly includes a rotation lever 311, a driving gear 312 and a lifting rack 41. The rotating rod 311 is coaxially connected to the end of the rotating shaft of the rotating motor 31, and the rotating rod 311 is located between the two connecting rods 22. Drive gear 312 fixed connection and coaxial setting are on dwang 311, and drive gear 312 is located 6 tops on ground and is located protective housing 23, and protective housing 23 can shelter from drive gear 312, makes drive gear 312 be difficult for exposing the site work personnel of accidental injury. Spacing logical groove 231 has been seted up on the top surface of protective housing 23, set up on the bottom surface of protective housing 23 with the guiding groove 232 of spacing logical groove 231 intercommunication, guiding groove 232 is located the opening part of spacing logical groove 231 bottom, guiding groove 232 and the coaxial setting of spacing logical groove 231, guiding groove 232 is by supreme the setting that reduces and contracts down.
Referring to fig. 1 and 2, the lifting rack 41 is fixedly connected to the top surface of the carrier table 4 near the peripheral side, the lifting rack 41 can be lifted into the limiting through groove 231 along with the carrier table 4 to engage with the driving gear 312, the lifting rack 41 can also be lifted into the limiting through groove 231 to disengage with the driving gear 312 along with the carrier table 4, and the guiding groove 232 is provided to facilitate guiding the lifting rack 41 to be lifted into the limiting through groove 231 to engage with the driving gear 312. The carrier table 4 can be raised until the bottom surfaces of the carrier table 4 and the lifting rack 41 are both above the ground 6 and adjacent to the ground 6.
Referring to fig. 1 and 2, when the telescopic rod 8 reaches the maximum contraction amount, the lifting rack 41 and the driving gear 312 are in a meshed state, and at this time, the support frame 5 is in a state of being detached from the ground 6, and the top surface of the support frame 5 in the detached state can rise along with the bearing table 4 until the top end of the second pulley 513 is higher than the top end of the i-shaped wheel 32; the plummer 4 is provided with a compensating piece, one end of the connecting cable 33 far away from the spool 32 is connected with the plummer 4 through the compensating piece, and the compensating piece is used for rolling or loosening one end of the connecting cable 33 far away from the spool 32. When the support frame 5 is in a state of being detached from the ground 6, one end of the connecting cable 33 far away from the spool 32 is converted into a releasing state from a rolling state.
When the worker is finished in the pipe shaft 11 and needs to leave the pipe shaft 11, the bearing platform 4 is lifted under the winding of the connecting cable 33, the telescopic rod 8 enters the contraction process, and the lifting rack 41 and the driving gear 312 are in a disengaged state.
Along with the continuous rising of plummer 4, until lifting rack 41 gets into spacing logical groove 231 and meshes with drive gear 312, can set up the telescopic link 8 at this moment and be in the maximum shrink state according to actual conditions. The rotation of the rotating motor 31 is stopped, the supporting frame 5 is detached from the ground 6, and the compensating member releases the end of the connecting cable 33 away from the spool 32 to compensate for the length of the connecting cable 33 required when the lifting rack 41 is lifted, before which the end of the connecting cable 33 away from the spool 32 is in a rolling state. Then, the rotating motor 31 is started again, the driving gear 312 is driven to rotate continuously, so that the lifting rack 41 is driven to ascend, the bearing platform 4, the supporting frame 5 and the telescopic rod 8 reaching the maximum contraction state are driven to ascend continuously until the bottom surfaces of the bearing platform 4 and the lifting rack 41 are located above the ground 6, and the auxiliary device for pipe well 11 construction can be conveniently translated to other positions from the position of the pipe well 11.
When the staff need get into in the tube well 11, will be located the plummer 4 of 6 tops on ground and remove to aim at the tube well 11 mouths, the staff stands from 6 tops on the plummer 4 on the ground again, because the plummer 4 is located 6 tops on the ground and adjacent with ground 6, consequently can improve the staff and stand the ease on the plummer 4. During the process that the lifting rack 41 is meshed with the driving gear 312 and descends, the end of the connecting cable 33 far away from the spool 32 is converted into the rolling state from the loosening state again under the action of the compensating piece.
If the lifting rack 41 and the driving gear 312 are not arranged, when the telescopic rod 8 reaches the maximum contraction state, the worker leaves from the tube well 11 in two ways: one is that the support frame 5 is still arranged on the ground 6, the bearing platform 4 is still positioned in the tube well 11, and the telescopic rod 8 still has a certain length when reaching the maximum contraction state, so that if a worker wants to leave from the tube well 11 at the moment, the worker needs to overcome the length when the telescopic rod 8 is in the maximum contraction state and stride out or climb out the opening of the tube well 11, and the operation is inconvenient; the other type is that after the telescopic rod 8 reaches the maximum contraction state, the support frame 5 is detached from the ground 6, and then the connecting cable 33 continues to be wound, but after the support frame 5 is detached from the ground 6, the fulcrum of the connecting cable 33 on the support frame 5 can swing along with the support frame 5, so that the stability of the bearing table 4 in the process of ascending to the position above the ground 6 is poor, and potential safety hazards are generated.
Referring to fig. 1, 3 and 5, the compensating element is a coil spring 42, one end of the coil spring 42 where an inner ring is located is fixedly connected to the bearing table 4 through a support rod 43, and the other end of the coil spring 42 is connected to one end of the connecting cable 33 far away from the spool 32, that is, one end of the connecting cable 33 far away from the spool 32 is fixedly connected to the bearing table 4 through the coil spring 42. In the natural state of the coil spring 42, the end of the connecting cable 33 remote from the spool 32 is wound up by the coil spring 42. The top surface of the bearing table 4 is fixedly connected with a mounting rod 44 at a position close to the peripheral side edge of the bearing table, a fixing bolt 45 penetrates through the connecting cable 33, and the fixing bolt 45 is in threaded connection with the mounting rod 44 and is used for fixing the wound connecting cable 33. A turning handle 46 is fixedly connected to the nut of the fixing bolt 45 to facilitate the worker to loosen or tighten the fixing bolt 45. Two mounting covers 47 are fixedly mounted on the top surface of the bearing table 4, and the mounting covers 47 are correspondingly covered on the coil springs 42, so that the coil springs 42 are not easily interfered.
In the process that the lifting rack 41 is meshed with the driving gear 312 and descends, one end of the connecting cable 33, far away from the spool 32, can be automatically converted from a loosening state to a rolling state under the action of the coil spring 42 and is fixed through the fixing bolt 45, and the structure is simple. When the end of the connecting cable 33 remote from the running wheel needs to be changed from the winding state to the releasing state, the fixing bolt 45 is unscrewed from the mounting rod 44.

Meanwhile, the lifting rack 41 is descended from the state of being meshed with the driving gear 312 to the state of being disengaged, when the support frame 5 descends to the ground 6, the support frame 5 is fixed through the pin 53, at the moment, one end, far away from the spool 32, of the connecting cable 33 is automatically converted from the loosening state to the rolling state under the action of the coil spring 42, a worker fixes the connecting cable 33, wound on the coil spring 42, on the bearing table 4 through the fixing bolt 45, then the bearing table 4 descends continuously, and the worker is transported to the position with the designated height in the pipe well 11 for construction.
(2) Leaving the tube well 11: when the worker is finished in the pipe shaft 11 and needs to leave the pipe shaft 11, the bearing platform 4 is firstly rolled up and lifted at one end of the connecting cable 33 close to the spool 32, and the telescopic rod 8 enters the contraction process, so that the lifting rack 41 and the driving gear 312 are still in a disengaged state. With the continuous rising of plummer 4, until lifting rack 41 gets into spacing logical groove 231 and meshes with drive gear 312, can set up telescopic link 8 at this moment and be in the maximum shrink state according to actual conditions.
The rotation of the rotary motor 31 is stopped, the support frame 5 is removed from the floor 6, and at this time, the fixing bolt 45 on the mounting rod 44 is unscrewed, so that the coil spring 42 loosens the end of the connecting cable 33 away from the spool 32 to compensate for the required length of the connecting cable 33 when the lifting rack 41 is lifted, and before that, the end of the connecting cable 33 away from the spool 32 is in a rolling state. Then, the rotating motor 31 is started again, the driving gear 312 is driven to rotate continuously, so that the lifting rack 41 is driven to ascend, the bearing platform 4, the support frame 5 and the telescopic rod 8 reaching the maximum contraction state are driven to ascend continuously until the bottom surfaces of the bearing platform 4 and the lifting rack 41 are located above the ground 6, and the worker strides over the bearing platform 4 to the ground 6 to leave the pipe well 11 after construction.
