The method of general measure steel wire rope or cable G.I.H depth is to use the wired transmission of quad and reception, well head
All more than 60 meters, the cable of wire transmission mode is naked to be placed on the ground of well site distance with working rig, easily insulation be present not
The failure such as good, short-circuit, breaking is, it is necessary to often safeguard, change；Particularly when constructing cold season, cable is held by low temperature effect
Cracky fractures；During hot weather construction, in the case that sealing property is bad at the cable interface, it is easy to intake, so as to cause work
As when become attached to destruction, count inaccurate and influence operation.
The content of the invention
Lower sheave device is counted with wireless depth it is an object of the invention to provide a kind of well mouth of oil well, is solved existing wired
Transmission easily has that cable insulation is bad, the failure such as short-circuit, breaking, damaged；Solves the problems such as wire transmission operation is wasted time and energy.
The technical scheme adopted by the invention to solve the technical problem is that：A kind of well mouth of oil well counts ground with wireless depth and slided
Wheel apparatus, including fixing chuck plate, main board a, main board b, open slot, bearing pin, limit shaft, pin socket a, pin socket b, pulley,
Head bolts, oiling nozzle, end cap, gear fixing screws, square key, driving gear, terminal block ring, stop collar, main shaft, shaft nut,
Bearing, counter, backing pin, clamp pin, counter emitter gear, counter lock pin, it is characterised in that：Described pin socket a
It is separately fixed at pin socket b with engagement thread on main board a and main board b, backing pin floats and is through pin socket a and pin socket b
Centre, described counter be arranged on main board a bottoms open slot in, counter emitter gear and driving gear are ratcheting
Afterwards, counter lock pin automatic clamping positions on main board a breach.
Beneficial effects of the present invention：A kind of well mouth of oil well proposed by the present invention counts lower sheave device, solution with wireless depth
The problem of definite transmission of having determined operation is wasted time and energy, the signal that count receiver is spread out of with wireless receiving emitter, which is realized, to be counted,
The appearance of bad, short-circuit, breaking, damaged etc. the failure of cable insulation is prevented；Realize reliable operation, quick for installation, maintenance side
Just the problems such as.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1-2, a kind of well mouth of oil well of the invention counts lower sheave device, including fixing chuck plate with wireless depth
1, main board a201, main board b202, open slot 203, bearing pin 3, limit shaft 4, pin socket a5, pin socket b6, pulley 7, end cap
Screw 8, oiling nozzle 9, end cap 10, gear fixing screws 11, square key 12, driving gear 13, terminal block ring 14, stop collar 15, main shaft
16, shaft nut 17, bearing 18, counter 19, backing pin 20, clamp pin 21, counter emitter gear 22, counter lock pin 23
Composition；Main board is made up of main board a201 and main board b202, and main board is made up of carbon steel, main board a201, main board
B202 is connected by main shaft 16, bearing pin 3, limit shaft 4；Pin socket a5 and pin socket b6 are separately fixed at main board with engagement thread
On a201 and main board b202, backing pin 20, which floats, is through pin socket a5 and pin socket b6 centre, and oiling nozzle 9 is arranged on end cap 10
On, end cap 10, bearing 18, stop collar 15, terminal block ring 14 form a lubricating grease circulation passage, and head bolts 8 consolidate end cap 10
It is scheduled on pulley 7, square key 12 serves main shaft 16 and main board between main shaft 16 and main board a201, main board b202
The effect that a201, main board b202 are mutually rotated, main shaft 16 are fixed on main board a201 and main board by shaft nut 17
On b202, fixing chuck plate 1 is fixed between main board a201 and main board b202 by bearing pin 3, and driving gear 13 is consolidated with gear
Determine the side that screw 11 is fixed on end cap 10, counter 19 is arranged in the open slot 203 of main board a201 bottoms, counter hair
Penetrate machine gear 22 and driving gear 13 it is ratcheting after, the automatic clamping of counter lock pin 23 positions on main board a201 breach, steel wire
Rope or banded cable movable pulley 7 rotate, and the driving gear 13 of the end face of pulley 7 drives counter emitter gear 22 to rotate and send nothing
