Abstract
The utility model relates to the technical field of depth measurement of rotary drilling rigs, in particular to an engineering machinery depth measuring precision device. The engineering machinery depth measuring precision device comprises a main winch tail end bearing, a tail end support seat body, a fixed shaft, a bolt, an encoder supporting seat and an encoder. The main winch tail end bearing is arranged in the tail end support seat body, and the tail end of the main winch tail end bearing is provided with the fixed shaft. The encoder supporting seat is fixed on the tail end support seat body through the bolt, the encoder is connected with an encoder shaft sleeve, and a torsion resistance spring is arranged in the encoder shaft sleeve. The encoder shaft sleeve is fixed on the encoder through an encoder shaft sleeve locking bolt. The number of turns on a main winch rolling cylinder of each layer of wire steel rope is preset in a program, when in calibration, just the total number of turns of the steel wire rope on the main winch rolling cylinder needs to be input so that the number of turns of the steel wire rope on the rolling cylinder at the present can be known through calculation of a controller. Further, a corresponding proportionality coefficient is utilized for calculation of measuring depth, and effects on depth measuring caused by diameter changing is removed.
Description
Technical field
The utility model relates to the rotary drilling rig technical field that fathoms, especially a kind of engineering machinery total accuracy of sounding device.
Background technology
Need to advance to measure to digging drilling depth in rotary drilling rig work, be directly at the master winch end bearing encoder to be installed at present, and this mode is except existing the reducing impact to also have when machine is acutely shaken, and certainty of measurement can not be guaranteed.Existing scheme is utilized encoder scheme to creep at rotary drilling rig to cause fathoming inaccurate when acutely shake the rock stratum, and long-term work is under jitter conditions, causes encoder fault rate height and the optoelectronic switch problem that reliability can not be guaranteed under adverse circumstances.
The utility model content
The deficiency that can not be guaranteed in order to overcome existing rotary drilling rig certainty of measurement, the utility model provide a kind of engineering machinery total accuracy of sounding device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of engineering machinery total accuracy of sounding device, comprise the master winch end bearing, the end support pedestal, fixed axis, bolt, encoder supporting seat and encoder, described master winch end bearing is installed in the end bearing pedestal, described master winch end bearing end is provided with fixed axis, described encoder supporting seat is bolted on the end bearing pedestal, described encoder connects the encoder axle sleeve, be provided with torsion spring in the described encoder axle sleeve, described encoder axle sleeve is fixed on the encoder by encoder axle sleeve tight fixed bolt.
The beneficial effects of the utility model are, this engineering machinery total accuracy of sounding device presets every layer of wire rope and can twine the number of turns on the master winch cylinder in program, as long as timing signal is the number of total coils of input wire rope on the master winch cylinder, calculate the number of turns that can draw on the cylinder of the present place of wire rope by controller, and then adopt the corresponding calculating that fathoms than row coefficient, eliminated the impact that reducing produces depth measurement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is encoder schematic diagram of the present utility model;
Among the figure 1, the master winch end bearing, 2, the end bearing pedestal, 3, fixed axis, 4, bolt, 5, the encoder supporting base, 6, the encoder axle sleeve, 7, encoder axle sleeve tight fixed bolt, 8, encoder, 9, torsion spring.
The specific embodiment
Structural representation of the present utility model such as Fig. 1, a kind of engineering machinery total accuracy of sounding device, comprise master winch end bearing 1, end support pedestal 2, fixed axis 3, bolt 4, encoder supporting seat 5 and encoder 8, described master winch end bearing 1 is installed in the end bearing pedestal 2, described master winch end bearing 1 end is provided with fixed axis 3, described encoder supporting seat 5 is fixed on the end bearing pedestal 2 by bolt 4, described encoder 8 connects encoder axle sleeve 6, be provided with torsion spring 9 in the described encoder axle sleeve 6, described encoder axle sleeve 6 is fixed on the encoder 8 by encoder axle sleeve tight fixed bolt 7.
This engineering machinery total accuracy of sounding device, master winch end bearing 1 fix one with master winch coaxial and rigidly connected fixed axis 3, encoder 8 usefulness bolts 4 are fastened on the end bearing pedestal 2, utilize torsion spring to be flexible coupling 3 fixing on the encoder axle sleeve 6 that stretches out on the encoder 8 and the master winch end bearing 1 of fixed axis again, avoided causing because of vibrations the deficiency of measuring.The impact that depth measurement is produced in order to eliminate reducing, in program, preset every layer of wire rope and on the master winch cylinder, can twine the number of turns, as long as timing signal is the number of total coils of input wire rope on the master winch cylinder, calculate the number of turns that can draw on the cylinder of the present place of wire rope by controller, and then adopt the corresponding calculating that fathoms than row coefficient, eliminated the impact that reducing produces depth measurement.
