Abstract
The utility model aims to provide a touchdown detection device for drill rods of rotary drilling rigs, which is designed for solving the problem that in the prior art, operators can not accurately monitor the state of the head part of a drill rod in real time, thereby often causing a phenomenon that a steel wire rope of a main hoist is unordered. According to the scheme, the touchdown detection device for drill rods of rotary drilling rigs is characterized by comprising a hoisting pulley arranged on a hoisting mechanism of a rotary drilling rig; the hoisting pulley is provided with a pin shaft sensor, a data acquisition unit and a wireless signal transmitting device which are sequentially connected; and the touchdown detection device also comprises an information processing device arranged in an operation chamber of the rotary drilling rig, a wireless signal receiving device matched with the wireless signal transmitting device is arranged in the information processing device, a computer which is connected with the wireless signal receiving device and is used for processing signal data is also arranged in the information processing device, and the information processing device is also provided with an information output terminal connected with the computer.. By using the touchdown detection device provided by the utility model, operators can accurately monitor the state of the head part of the drill rod in real time, thereby avoiding a phenomenon that a steel wire rope of a main hoist is unordered.
Description
Technical field
The utility model relates to a kind of rig that is used for the land transport device that has.
Background technology
Rotary drilling rig is a kind of multi-functional, high efficiency pouring pile hole equipment.Noise was little when it had construction, friction, no soil deformation, displacement; Little to surrounding constructure influence, the stake footpath is big, and length can freely be selected; And can enlarge the bottom, pile body stiffness is big, and bearing capacity of single pile is big; Efficient is high, and system stake low cost and other advantages, is approved by domestic basic engineering institute and unit in charge of construction at present.Along with the increase of rotary drilling rig recoverable amount on market, the user also proposes higher requirement to the functional performance of rotary drilling rig.As: rotary drilling rig often occurs because of operator's error causes the phenomenon of master winch wire rope disorder cable, thereby causes wire rope low application life in work progress, and sounding error is big.
The utility model content
The utility model is intended to provide a kind of rotary drilling rig drilling rod checkout gear that contacts to earth, and to solve the monitoring drilling rod head state that operator of the prior art can't be accurately real-time, causes the problem of master winch wire rope disorder cable often.
The purpose of the utility model can reach through following measure: the checkout gear that contacts to earth of the rotary drilling rig drilling rod in this programme; It is characterized in that: comprise the elevator pulley that is installed on the rotary drilling rig hoisting mechanism; The elevator pulley is provided with bearing pin sensor, data acquisition unit and the wireless signal transmitting device that connects successively; Also comprise and be used to be located at the information processor in the rotary drilling rig operating room; Be provided with wireless signal receiving system in the information processor with said wireless signal transmitting device coupling; Also be provided with in the information processor be connected with the wireless signal receiving system be used for processing signals data computing machine, also be provided with the information outlet terminal that is connected with said computer on the information processor.
Said elevator pulley is installed on the hoisting mechanism of rotary drilling rig, and drilling rod is fixed with the wire rope that is wrapped on the elevator pulley.In the course of work; The bearing pin sensor is monitored the stress of elevator pulley at any time; And signal sent to the computer in the information processor through data acquisition unit and wireless signal transmission/receiving system, after drilling rod contacted to earth, drilling rod acted on pull of steel wire and is certain to tangible minimizing; Computer then can detect described variation; Contact to earth to judge that drilling rod is actual, remind the operator through the information outlet terminal then, said information outlet terminal can be the various devices that can send alerting signal such as loudspeaker, display, alarm lamp.
Data acquisition unit carries out operations such as AD conversion and the coding of signal, and the also available wireless signal transmitting device of transferring to of encoding operation is accomplished, and computer then can be to the information of receiving processing such as decode.
Computer carries out initialization in the back that powers on to the drilling rod automatic stop control functional module of contacting to earth; Then the bearing pin sensor signal that collects is put, analyzes in order the back and obtain reference data; Reference data steel wire rope tension data real-time and initial setting compare; If reference data is less than the data of setting then send control signal; Simultaneously current depth measurement data are also caught up with the depth measurement data of preserving when once holing and are compared, if data of preserving when hole less than the last time then report to the police to the information outlet terminal are in position at the bottom of the hole, hole otherwise give tacit consent to drilling rod; If reference data is greater than the data of setting then Vehicle Controller is not sent out control signal, the operator normally transfers drilling rod.
Further: said information outlet terminal is a LED display.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the sketch map of rotary drilling rig top hoisting mechanism among the utility model embodiment.
The specific embodiment
Known concrete structure and characteristic are no longer set forth at this in the following proposal.As shown in Figure 1: the rotary drilling rig hoisting mechanism includes elevator pulley 1; The bearing pin of installing in the elevator pulley 2 is provided with the bearing pin sensor; Signal treatment box 3 also is installed in elevator pulley 1; The data acquisition unit and the wireless signal transmitter that are connected are installed in it, information processor is installed in driver's cabin, also be provided with the wireless signal receiver, computer and the LED display that are connected on the information processor.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
