Specific embodiment
Embodiment 1:
It referring to Fig.1~2, is the structural schematic diagram of the embodiment of the present invention 1, a kind of socket bearing capacity test method, including steel
Cord 7 and the socket 6 for being cast in 7 both ends of wirerope, include the following steps,
Then the first step, connection are linked together the wirerope 7 that two pour socket 6 by rope card 8,7 He of wirerope
Socket 6 is placed in testing stand 1；
Second step, assembling, two connecting rods 2 are inserted into from 1 two sides of testing stand respectively, and are connect respectively with two sockets, two
A hydraulic jack 3 is set in the connecting rod 2 at 1 both ends of testing stand, and nut 4 and gasket 5 press from both sides hydraulic jack 3
Between gasket 5 and testing stand；
Third step, detection, hydraulic jack 3 push gasket 5 and nut 4, and nut 4 drives connecting rod 2, and connecting rod 2 passes through
The classification of hydraulic jack 3 is forced into preset value, and continues 5min, while observing socket 6 and steel wire by 6 tense wire rope 7 of socket
Whether 7 places of pouring of rope slide；
4th step, recycling are connected by second step Connection Step disassembly lower connecting rod 2 with socket 6 after third step detection
It connects, the socket of no sliding, waits construction usage, have the socket of sliding, pour again, be back to the first step.
In actual use:
The first step after socket 6 is cast in the cooling of 7 both ends of wirerope at the construction field (site), chooses two steel for pouring socket 6
Cord 7, one of 7 one end of wirerope are placed side by side on the side of other 7 one end of steel cable, at this time two wirerope 7
The socket 6 of this one end is located at opposite position, then the socket 6 of two 7 this one end of wirerope connects this one end not in the same side
The wirerope 7 and socket 6 being connected together are placed on 1 centered position of testing stand.
Connecting rod 2 is inserted into testing stand 1 by second step by two connecting rods 2 respectively from testing stand 1 even lonely insertion
One end is connect with 6 pin shaft of socket, then hydraulic jack 3 and gasket 5 and nut 4 is successively through in connecting rod 2, hydraulic thousand
Jin 3 one end of top and 1 end thereof contacts of testing stand, the other end are contacted with gasket 5, and nut 4 is threaded in this side of connecting rod 2, together
When 1 both ends of testing stand while nut 4 screw, then hydraulic jack 3 is connected to the fluid pressure drive device in place.
Third step drives the hydraulic jack 3 at 1 both ends of testing stand by the fluid pressure drive device of construction site simultaneously
Dynamic, hydraulic jack 3 drives end to stretch out, 3 both ends of hydraulic jack simultaneously testing stand 1, push gasket 5 and nut 4, gasket at this time
5 and nut 4 it is mobile far from 1 direction of testing stand, since nut 4 is threadedly coupled with connecting rod 2, make the drive shifting of connecting rod 2 of nut 4
Dynamic, connecting rod 2 pulls socket 6, and socket 6 pulls the wirerope 7 of connection, since two wirerope 7 pass through 8 connection of rope card, steel wire
Rope 7 is not in sliding, then carries out driving hydraulic jack 3, driving hydraulic thousand by the fluid pressure drive device classification at scene
Lotus 5min is held behind jin top 3 to pressure bearing capacity, socket 6 is then observed and wirerope 7 pours whether part has sliding, then stop
Fluid pressure drive device drives hydraulic jack 3.
4th step by nut 4, gasket 5, hydraulic jack 3 and connects after detection according to second step Connection Step
Bar 2 disassembles, the socket 6 of no sliding, waits construction usage, has the socket 6 of sliding, pour again, is choosing two again
Wirerope 7 is detected.
Embodiment 2:
