Abstract

The utility model discloses a sounding gear of a rotary drilling rig, which comprises at least two depth inspection switches (2). A fluted disc is fixedly arranged on one side end of a winding drum (5), a mounting support (1) is arranged on a winding bracket (7) on the same side with the winding drum (5) provided with the fluted disc, and then the mounting support (1) is arranged between the winding bracket (7) and the fluted disc; and the two depth inspection switches (2) are arranged on the mounting support (1) to detect corresponding to the fluted disc. The utility model is the sounding gear of the rotary drilling rig which has accurate measurement, convenience in installation and maintenance, and can adapt to the operation requirement of rotary drilling in a severe condition.

Description

A kind of sounding gear of rotary drilling rig
Technical field
The utility model relates to a kind of sounding gear, is specifically related to the device that the elevator individual layer holds a kind of rotary drilling rig survey drilling depth of rope layout.
Background technology
At present the rotary drilling rig main depth measurement mode of holing has two kinds:
The first is at the catead master rear wheel place of mast top a sensor driver plate to be installed, and welds a depth detection switch installation board at the catead place.Install with screw fastening between this scheme sensor driver plate and the pulley, the sensor driver plate rotates with pulley, and pulley is installed in two NJ319E(or other models) on the type housing washer, inner ring links to each other with bearing pin, and the bearing pin place is provided with lubrication hole.Not enough everywhere below this detection mode exists: 1, there are slip in pulley and wire rope, and easy pulse-losing signal is so that depth measurement is inaccurate; 2, the driver plate number of teeth affects total accuracy of sounding, and is very high to the requirement of sense switch installation accuracy when the number of teeth is many, otherwise phase place is not right, can't fathom; 3, it is different according to the inductive switch model that the coverage that can sense because of the depth detection switch is generally 4-8mm(), the flatness of driver plate has influence on the collection of pulse signal; 4, there is certain angle because reel steel wire ropes goes out between rope tension and the pulley, the flatness of pulley relative depth sense switch is affected, damage easily or the wearing depth sense switch, cause electric fault.
The second is fastenedly connected drive this rotary encoder with gear or belt pulley with pulley for a rotary encoder is installed at the catead place.This detection mode defective has 2 points: 1, install and safeguard inconvenience, high cost; 2, the degree of protection of rotary encoder and anti-seismic performance are difficult to reach revolve and dig abominable working condition requirement, damage easily, and fault rate is high.
Facts have proved that rotary drilling rig boring sounding gear fault rate and maintenance cost are too high at present, the utmost point need be introduced new departure and improve the depth measurement scheme, reduces equipment loss.
The utility model content
Technical problem to be solved in the utility model provide a kind of measurement accurately, installation and easy to maintenance, can adapt to the sounding gear that revolves the rotary drilling rig that digs abominable working condition requirement.
In order to solve the problems of the technologies described above, the sounding gear of the rotary drilling rig that the utility model provides, comprise at least two depth detection switches, fluted disc is fixedly mounted on a side of reel, and be equipped with and on the winding support of homonymy of reel of described fluted disc erection support be installed and described erection support is between described winding support and the described fluted disc, two described depth detection switches are installed in corresponding detection with described fluted disc on the described erection support.
Described erection support is provided with guard shield, and the head of described depth detection switch is in the end face of described guard shield.
Described fluted disc is comprised of two semilune fluted discs.
Described erection support is installed on the described winding support with bolt.
Described two semilune fluted discs are installed in a side of described reel with screw.
Adopt the sounding gear of the rotary drilling rig of technique scheme, the characteristics of this mounting structure are to be particularly suitable for individual layer to hold rope layout elevator; Signal detection is reliable, fundamentally solves the electric fault that slip between pulley and the wire rope causes the angle impact between the losing of pulse signal, lineoutofservice signal pull direction and the pulley plane to cause; The band protective device, cost is low, and (minimizing work high above the ground) easy to maintenance is installed simply.
The utility model is fit to revolve and digs bad working environments; signal detection is accurate; simple in structure; economical and practical; easy for installation, reduced the generation of electric fault with the erection support of protective effect, the depth measurement switch is directly installed on fundamentally to have solved on the reel it is installed in the variety of issue that catead brings above; facts have proved that the depth measurement switch that is installed in the reel end is higher than other average life.
In sum, the utility model is that a kind of measurement is accurate, installation and easy to maintenance, can adapt to the sounding gear that revolves the rotary drilling rig that digs abominable working condition requirement.

Fig. 1 is mounting structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is depth detection switch erection support structural representation.
Fig. 4 is half-moon-shaped fluted disc structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4; fluted disc is comprised of two semilune fluted discs 3; two semilune fluted discs 3 adopt screw to be fixedly mounted on a side of reel 5; and be equipped with and adopt bolt 6 that erection support 1 and erection support 1 are installed on the winding support 7 of homonymy of reel 5 of two semilune fluted discs 3 to be between winding support 7 and two the semilune fluted discs 3; erection support 1 is provided with 8, two depth detection switches 2 of guard shield and is installed on the erection support 1 and the head of depth detection switch 2 is in the end face of guard shield 8 and two half-moon-shaped fluted disc 3 corresponding detections.
Its mounting method is divided into four steps: the first, two semilune fluted discs 3 are screwed left end at reel 5, and detect the flatness after two semilune fluted discs 3 are installed; The second, the reel 5 with semilune fluted disc 3 is installed on the winding support 7, install simultaneously the annexes such as reductor and motor; The 3rd, erection support 1 usefulness bolt 6 with guard shield 8 is installed on the winding support 7, simultaneously two depth detection switches 2 are installed on the erection support 1, notice that the head of depth detection switch 2 does not stretch out the end face of guard shield 8, note simultaneously the distance (apart from different and different with depth detection switch 2 specifications) between depth detection switch 2 and the semilune fluted disc 3; The 4th, debug phase, the wire rope 4 of on-load is circled (reel 5 has slight deformation during on-load) with reel 5 fortune, and the distance that checks depth detection switch 2 and semilune fluted disc 3 is qualified greater than 2/3rds of its mounting distance (mounting distance when wire rope 4 is zero load).
Depth detection switch 2 detects semilune fluted disc 3, thereby detects the revolution number of metering reel 5, thereby calculates the length of wire rope 4, calculates the degree of depth degree of rotary drilling rig boring.
