Face, and the depth on the first fixed link 2 insertion ground is adjusted, make the first tablet 1 vertical with timber 29, then pass through connecting rod 3
First tablet 1, by multiple holding 19 circumference uniform distributions of block in the compact heap 18 of 3 upper end of connecting rod, afterwards by one end of rope 11
The lower end of connecting rod 3 is fixed on, the other end of rope 11 is fixed on the upper end of the first pin, and adjusts 11 length of rope and make rope
11 are in tensioning state.
After above-mentioned state is adjusted, the state between connecting rod 3 and compact heap 18 can be to be fixedly connected with and separate two kinds
State.
When being fixedly connected between compact heap 18 and connecting rod 3, it is using process：Pull down the left and right sides of timber 29
Compression bar 5 outer end, since compression bar 5 and connecting rod 3 contact, so 5 the inner of compression bar can drive connecting rod 3 to move up, when even
Extension bar 3 is fixedly connected with compact heap 18, since the inclined-planes of multiple holding blocks 19 form up big and down small taper surface, and taper surface
End diameter is located between the end diameter and outside diameter of 18 conical cavity of compact heap, so when compact heap 18 moves up,
The male cone (strobilus masculinus) of block 19 is held in the inner conical surface extruding of compact heap 18 tightly, so that holding block 19 tightly holds timber 29 tightly；At the same time connecting rod 3
When moving up, rope 11 can be pulled and moved up with pawl 10, when holding timber 29 tightly due to holding block 19 tightly, compact heap 18
The distance moved upwards is consistent with the distance that pawl 10 when making the pawl 10 be separated with ratchet bar 9 moves, so 10 meeting of pawl and spine
Rack 9 departs from, and the second tension spring 16 can make push rod 8 move right, and similarly, first connecting rod 13 moves right and is turned out, and second
Connecting rod 14 is also turned out, so that two clamping blocks 12 unclamp timbers 29, continues to pull down compression bar 5, compact heap 18 continue to
Upper movement, while drive timber 29 to move upwards by holding block 19 tightly, it is pulled up timber 29.
Check the state that timber 29 is pulled out, can be again when the above process can not be such that timber 29 loosens completely and be pulled out
It is secondary to pull push rod 8 to the left, make the clamping timber 29 again of clamping block 12；Block 19 will be held tightly afterwards and unclamp timber 29 with compact heap 18,
5 angle of compression bar is adjusted to original state, so as to adjust the opposite position with timber 29 of compact heap 18, and adjusts the length of rope 11
Degree, makes rope 11 be in tensioning state, pulls down the outer end of the compression bar 5 of 29 both sides of timber again, and similarly, holding block 19 tightly can embrace
Tight timber 29, clamping block 12 unclamps timber 29 so that timber 29 is pulled out again, and so on, until timber 29 loosens completely
And it is pulled out.
When being separated between compact heap 18 and connecting rod 3, such a situation has two states：Compact heap 18 and connecting rod 3 it
Between no third compression spring 21 connect and connected between compact heap 18 and connecting rod 3 by the 3rd compression spring 21.
When separating between compact heap 18 and connecting rod 3 and being connected between the two without the 3rd compression spring 21, it uses process

Compact heap 18 moves up, similarly due to holding block 19 and the shape and structure of compact heap 18, so when compact heap 18 moves up
When, timber 29 can be held tightly by holding block 19 tightly, while when connecting rod 3 moves up, can be pulled rope 11 and be moved with pawl 10, and
So that clamping block 12 unclamps timber 29, the length of rope 11 is adjusted to relaxation state, continues to pull down compression bar 5, compact heap 18
Continue up, while drive timber 29 to move upwards by holding block 19 tightly, be pulled up timber 29.
Check the state that timber 29 is pulled out, can be again when the above process can not be such that timber 29 loosens completely and be pulled out
It is secondary to pull push rod 8 to the left, make the clamping timber 29 again of clamping block 12；Adjust what the second pin 26 coordinated with first through hole 25 afterwards
Position, makes the second pin 26 be located in the hole of top in the hole with once coordinating before first through hole 25, during adjustment, due to
12 clamping timber 29 of clamping block, so timber 29 will not drive holding block 19 and clamping block 12 to move down, thus can adjust rope
The length of rope 11, when the rope 11 is in tensioning state, there is a certain distance in 5 upper end of compression bar with 18 lower end of compact heap, this distance
Not less than making 9 separated distance of pawl 10 and ratchet bar；The outer end of the compression bar 5 of 29 both sides of timber is pressed, connecting rod 3 drives rope
11 movements make pawl 10 be separated with ratchet bar 9, so that clamping block 12 unclamps timber 29, connecting rod 3 may be also with not embracing at this time
Tight block 19 contacts, timber 29 and clamping block 12 have it is slight move down, but displacement distance is smaller, does not influence whole pile pulling
Process.
When being separated between compact heap 18 and connecting rod 3 and being connected with three compression springs 21 between the two, it is using process：
When pulling down the outer end of the compression bar 5 of the left and right sides of timber 29, the inner of compression bar 5 can drive connecting rod 3 to move up, due to this
When connecting rod 3 the top not end contact with the hole of the lower section of stepped hole 20, so the upper end of connecting rod 3 can compress the 3rd pressure
Spring 21, while the lower end of connecting rod 3 can pull rope 11, rope 11 is moved up with pawl 10, since connecting rod 3 is to moving up
Move 3 tip contact stepped hole 20 of connecting rod macropore and aperture joint face when the distance that moves be not less than pawl 10 and ratchet
9 separated distance of bar, so push rod 8 can be released, so that two clamping blocks 12 unclamp timber 29, continues to press the left side of timber 29
The outer end of the compression bar 5 of right both sides, compact heap 18 continue to move up, and timber 29 are held tightly by holding block 19 tightly, so that timber 29
It is pulled up.
Check the state that timber 29 is pulled out, can be again when the above process can not be such that timber 29 loosens completely and be pulled out
It is secondary to pull push rod 8 to the left, make the clamping timber 29 again of clamping block 12；Adjust what the second pin 26 coordinated with first through hole 25 afterwards
Position, makes the second pin 26 be located at and in the hole of the top in hole once coordinated before first through hole 25 and be in and initial state
Identical angle, adjusts the length of rope 11, rope 11 is in tensioning state.The left and right sides of timber 29 is pulled down again
The outer end of compression bar 5,3 upper end of connecting rod can first compress the 3rd compression spring 21, and lower section pawl 10 is separated with ratchet bar 9 at this time, and is blocked
Tight block 12 unclamps timber 29, and when clamping block 12 unclamps timber 29, the 3rd compression spring 21 of top is compressed, and the 3rd compression spring 21 is to upper
Square 18 1 upward power of compact heap, prevent compact heap 18 and timber 29 from declining；Continue to pull down the outer end of compression bar 5, timber
29 are pulled out again, and so on until timber 29 is all loosened and is pulled out.
