Abstract
The utility model provides a hydraulic chuck of a hydraulic drilling machine. The hydraulic chuck comprises a slip base. A hydraulic oil cylinder is arranged on the outer periphery of the slip base in a sleeved mode. One end of a piston in the hydraulic oil cylinder is fixedly connected with a top plate which is integrally connected with a chuck cap and a chuck cover. A disc spring is arranged at the bottom end of the top plate. According to the hydraulic chuck, through the opposite direction effect of piston pushing force and disc spring bounce force, clamping and loosening work of a drilling rod is achieved, the hydraulic chuck has the advantages of being simple in structure, clamping force is large, and the surface of the drilling rod cannot be damaged.
Description
Technical field
The utility model relates to the safety of coal mines equipment, relates in particular to a kind of coal mine drilling hydraulic drill rig.
Background technology
Rig is mainly used in exactly under coal mine creeping into gas and takes out (row) discharge hole, fluid injection fire-fighting hole, coal-bed flooding hole, protrusion-dispelling pressure relief vent, geological prospecting hole and other engineering hole etc.Because the rig work is big machinery, under severe traffic condition, effectively reduce the bulking value of rig under coal mine, be of great significance.Rig mainly is comprised of unit head, underframe, clamper, drilling tool etc., and wherein most crucial parts are unit heads, and it has determined overall volume and the weight of rig, so unit head transformation is necessary.
And drill power head mainly is comprised of hydraulic motor, transfer gear train, three parts of oild chuck.Hydraulic motor is converted to mechanical energy by hydraulic energy and provides power for rig; Oild chuck clamps drilling rod, to drilling rod transmitting torque and axial force, drives drilling tool realize revolution and creep into; Transfer gear train realizes the variation of different rotating speeds by different gear engagements.Because the oild chuck condition of work is more severe, require it must bear larger axial load and larger flywheel moment, and act frequently.
Oild chuck should, to drilling rod transmitting torque and gyration, transmit axially-movable and feed power to drilling rod again.In order to make the reliable operation of rig, oild chuck need guarantee that slips has enough clamping forces to drilling rod, and after clamping, self-lock ability is arranged, and makes axial or circumferential relative sliding not occur after slips clamping kelly; In addition, oild chuck clamps area and wants large, and clamp force distribution is wanted evenly, unlikely damage kelly surface.
The utility model content
In order to address the above problem, the utility model provides the oild chuck of a kind of coal mine drilling of rational in infrastructure, good clamping effect with hydraulic drill rig.
The technical solution of the utility model is:
A kind of oild chuck of hydraulic drill rig, comprise slip spider, and the periphery of described slip spider is arranged with hydraulic jack, and piston one end and top board in described hydraulic jack are affixed, and described top board and chuck cover, chuck lid link into an integrated entity, and described top board bottom is provided with the dish spring.
Further, the front end of described dish spring is provided with spring bearer plate, and described spring bearer plate is connected with pull bar, and the other end of described pull bar is connected with described chuck lid.
Operating principle of the present utility model is as follows: pressure oil enters chuck from the oil-in mouth, promotes piston and moves right, and piston is used in masterpiece on top board by thrust bearing.Because top board, chuck cover and chuck lid are connected as a single entity, so move to right under the effect of thrust bearing simultaneously, pull bar moves right simultaneously together, and drives spring bearer plate compact disc spring, makes the compression of dish spring, and the pressure on inclined-plane reduces and unclamps drilling rod like this.After hydraulic coupling cancels, the elastic force effect of dish spring promotes spring bearer plate towards moving left, and drives together with top board, chuck cover and chuck lid and is moved to the left by pull bar, thereby tighten drilling rod.
So be to be connected as a single entity because top board, chuck cover and chuck cover in oild chuck of the present utility model, thereby guarantee that slips has enough clamping forces to drilling rod; Due to the restriction that pull bar is arranged, so slips axial or circumferential relative sliding do not occur after clamping kelly.In addition, the relative direction effect of the thrust of the utility model by piston and the bounce of dish spring, realize to the clamping of drilling rod with unclamp work, have simple in structure, chucking power large and do not damage the characteristics on drilling rod surface.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1: the utility model structural representation.
In figure: 1-hydraulic jack, 2-piston, 3-top board, 4-chuck cover, 5-chuck lid, 6-butterfly spring, 7-spring bearer plate, 8-slip spider.
The specific embodiment
As shown in Figure 1, a kind of oild chuck of hydraulic drill rig, comprise slip spider 8, the periphery of described slip spider 8 is arranged with hydraulic jack 1, and piston 2 one ends and top board 3 in described hydraulic jack 1 are affixed, and described top board 3 links into an integrated entity with chuck cover 4, chuck lid 5, described top board 3 bottoms are provided with dish spring 6, the front end of dish spring 6 is provided with spring bearer plate 7, and described spring bearer plate 7 is connected with pull bar, and the other end of described pull bar is connected with chuck lid 5.
Pressure oil enters chuck from the oil-in mouth, promotes piston and moves right, and piston is used in masterpiece on top board by thrust bearing.Because top board, chuck cover and chuck lid are connected as a single entity, so move to right under the effect of thrust bearing simultaneously, pull bar moves right simultaneously together, and drives spring bearer plate compact disc spring, makes the compression of dish spring, and the pressure on inclined-plane reduces and unclamps drilling rod like this.After hydraulic coupling cancels, the elastic force effect of dish spring promotes spring bearer plate towards moving left, and drives together with top board, chuck cover and chuck lid and is moved to the left by pull bar, thereby tighten drilling rod.
Above-described embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model and all belonging in protection domain of the present utility model of modifying or change.
