The specific embodiment

In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 to Fig. 6:

Press a kind of detection force rod of low strain of foundation pile that the utility model is implemented, it includes tup 5, and tup 5 is made by nylon or plastics or hardwood or rubber material, and changes according to field condition.For the ease of changing, use suspension arrangement that tup 5 is fixed in hammer cover bottom, hammer cover includes hammer 3 and hammer body 6, hammer is 3 a hollow steel pipe, and hammer body 6 inside are set to hollow step-like, and hammer is the diameter of 3 diameters less than hammer body 6, the internal diameter of hammer body 6 is less than the diameter of tup 5, hammer has external screw thread to 3 lower end cars, and the inner car in hammer body 6 upper ends has internal thread, and hammer links to each other 3 with hammer body 6 screw threads.Suspension arrangement includes hammer folder 4, spring carrier arm 9, hammer folder 4 lower ends are set to up big and down small tongue-and-groove 42, tup 5 upper ends are provided with the tenon 51 corresponding with tongue-and-groove 42, tup 5 is assemblied in the hammer folder 4 times, such connected mode has limited the degree of freedom of the vertical direction of tup 5, can only move horizontally, will hammer folder 4 tenons 51 then into shape and be inserted in 6 li of tubular hammer bodies, tup 5 can not be moved in the horizontal direction together with tup 5 upper ends.Hammer folder 4 upper ends offer hanging hole 41, spring carrier arm 9 is formed by connecting by No. 8 iron wires and spring 92, the iron wire upper end curves the rectangle ring-type and forms upper end link 91, the centre bore of three hole cards 7 is passed the iron wire other end, and iron wire and spring 92 are linked, the iron wire of spring 92 lower ends penetrates bending sealing formation lower end link 93 in hammer folder 4 hanging holes 41.Spring carrier arm 9 upper end links 91 and latch 2 assemblings, the spring 92 at spring carrier arm 9 middle parts is tension after upper end link 91 and lower end link 93 all assemble, and spring 92 pulling force of generation are fixed on tup 5 bottom the hammer cover.

Latch 2 is assemblied in hammer on 3 by inserting in the latch groove 10, latch 2 is two pluckings, middle thin cylinders, latch groove 10 is the bar-shaped trough that the upper end width is big, the lower end width is little, the width of latch groove 10 upper ends is greater than the diameter at latch 2 two, the width of latch groove 10 lower ends is between the diameter at latch 2 two and middle diameter, so latch 2 inserts from the upper end of latch groove 10 during assembling, latch 2 card jails are in latch groove 10 lower ends under the pulling force of spring carrier arm 9.

For the ease of the pull-up suspension arrangement with conveniently assemble and disassemble, be with movable handle 8 on the suspension arrangement, movable handle 8 comprises card 7 and is the steel wire draw ring of U type, card 7 is provided with three through holes, middle through hole is assemblied between the upper end link 91 and spring 92 of spring carrier arm 9, steel wire draw ring two head ends are converted into triangle after passing the through hole of card 7 both sides, the length of steel wire draw ring greater than latch 2 from hammer the distance on 3 tops.During 8 pull-ups of activity handle, because the interstitial hole of card 7 is less than the link of spring carrier arm 9 upper ends, thereby with suspension arrangement, tup 5 together with latch 2 pull-ups to the upper end sipes of latch groove 10, pour out hammer folder 4 and tup 5, the i.e. tup 5 of replaceable unlike material after extracting latch 2 out.Hammer has fastening bolt 1 to 3 top thread connection, and fastening bolt 1 is tightened the posterior end and propped up latch 2, and latch 2 jumps up when preventing hammering, can also block foreign matter in use in addition and fall into.Fastening bolt 1 is to process with rigid plastics, because itself is not subjected to shearing force, the power that is squeezed is also very little, and selecting plastic material is for the ease of dismounting, just can unscrew with hand.

The installation steps of the utility model embodiment:

(1) will hammer into shape 3 and hammer body 6 usefulness screw threads tighten;

(2) mounting spring hook 9 and movable handle 8, detailed process is: No. 8 an iron wires upper end is bent into the rectangle ring-type, the centre bore of three hole cards 7 is passed the iron wire other end, iron wire and spring 92 link, the iron wire of spring 92 lower ends penetrates bending sealing in hammer folder 4 hanging holes 41, forms spring carrier arm 9; No. 8 iron wires of another root are curved U-shaped, and two holes, both sides of three hole cards 7 are passed at two ends, and the iron wire end is curved triangle respectively, make it can not deviate from three hole cards 7, formation activity handle 8;

(3) tup 5 is assemblied in the tongue-and-groove 42 of hammer folder 4, the tenon 51 of hammer folder 4 together with tup 5 advanced in the hammer body 6, will hammer into shape, the draw ring of movable handle 8 just can be skidded off standing upside down;

(4) upwards pull at movable handle 8, drive three hole cards 7, spur rectangular upper end link 91, when upper end link 91 through hammer during 3 latch groove 10 places, garden shape latch 2 is injected hammer in 3 the latch groove 10, unclamp movable handle 8,, tup 5 is combined closely with hammer body 6 because spring 92 produces tension;

(5) drawing movable handle 8 to advance hammer in 3 the cavity, hammering the fastening bolt 1 of screwing on into shape 3 place suitable for reading, fastening bolt 1 is tightened the posterior end and is propped up latch 2, and latch 2 comes off when preventing hammering, also can block foreign matter and fall into.

The demounting procedure of the utility model embodiment:

Unclamp fastening bolt 1, will hammer into shape, pour out movable handle 83 inversions; 2, upwards pull at movable handle 8, make latch 2 rise to sipes place, latch groove 10 upper end, take out latch 2, unclamp movable handle 8, hammer folder 4 splits away off from hammer body 6, takes out tup 5 and gets final product.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
