Embodiment：Before test, the connection ring 4 of the both sides of lower box body 22 is set on take-up bar 13 first, and
Along the slide downward lower box body 22 of take-up bar 13 bottom of connection ring 4 is contradicted with the top of spacing ring 131, then will fastening
Nut 132 is threaded on take-up bar 13, is stably connected to lower box body 22 by spacing ring 131 and clamp nut 132
On take-up bar 13.Then the sounding line between metallic channel 121 and detection hole is respectively placed in each separated time groove 2 32.Then will
Upper cartridge body 21 is docked at the top of lower box body 22 and the plug connector 7 of lower box body 22 is inserted in the Coupling 6 of upper cartridge body 21, so that will
Upper cartridge body 21 and lower box body 22 connect, while 22 semicircular separated time of the semicircle separated time groove 1 of upper cartridge body 21 and lower box body
Groove 2 32 forms circular separated time groove 3.Sounding line is set to enter detection hole detection base pulling the sounding line passed from bunching box 2 manually
During stake depth, sounding line is integrated and shunted by bunching box 2, so as to reduce the moving direction because of each sounding line with
The inconsistent situation for causing sounding line easily to be slid between each metallic channel 121 of depth measurement wheel 12 in the direction of each metallic channel 121.
Embodiment 2：A kind of pile measurement counting pulley, is with the difference of embodiment 1, as shown in Figures 6 and 7,
Connector includes buckle 8 and grab 9, buckle 8 is provided with 4 altogether in the present embodiment, respectively symmetrically be distributed in lower box body 22
The left and right sides, the grab 9 to match with buckle 8 is provided with the corresponding position of buckle 8 on upper cartridge body 21.Buckle 8 includes
Fixture 81, fixture 81 are fixedly connected on lower box body 22, serve fixed and spacing, are rotatably connected on fixture 81
Tumbler 82, connecting rod 83, the intermediate thread of connecting rod 83 are rotatably connected in the side close to fixture 81 on tumbler 82
Screw buckle 84 is connected with, grab 9 matches with screw buckle 84 allows the one end of screw buckle 84 away from connecting rod 83 securely
Ride on grab 9.
As shown in fig. 7, by rotate up tumbler 82 can drive with tumbler 82 be rotatablely connected connecting rod 83 to
Upper movement, and then promote the screw buckle 84 being threadedly coupled with connecting rod 83 to move up, you can screw buckle 84 is taken off from grab 9
Separate out and, so as to which upper cartridge body 21 is removed from lower box body 22.Similarly, it is necessary to which upper cartridge body 21 is held in into lower box body 22
When, first the one end of screw buckle 84 away from connecting rod 83 is ridden on grab 9, is then rotated down tumbler 82, if lower box
Connect not close between body 22 and upper cartridge body 21, it can also be made to extend further into connecting rod 83 by rotating screw buckle 84,
To shorten distance of the screw buckle 84 between grab 9, make connection even closer.
As shown in fig. 7, upper cartridge body 21 is provided with limited block 211 in the side contradicted with lower box body 22, limited block 211 is located at
Close to one end of connection ring 4, the groove 221 to match with limited block 211 is provided with upper cartridge body 21, in upper cartridge body 21 and lower box
During body 22 docks, reduce upper cartridge body 21 and the connection procedure of lower box body 22 by the way that limited block 211 is embedded in groove 221
There is the situation of relative displacement in middle upper cartridge body 21 and lower box body 22 so that connection procedure is more convenient.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
