Background technology
For the rock drilling degree of depth of effective expansion rig, and do not increase equipment size, many in the world rigs all are furnished with drill pipe storage, realize expanding the rock drilling degree of depth of rig by connecting and disconnecting drill rod.Domestic most of large type drill does not all design drill pipe storage, and the rock drilling degree of depth is restricted.And the drill pipe storage that external large type drill is furnished with, but complex structure, the action of grasping drilling rod needs 3～4 group oil cylinders participation action to finish.
The utility model content
The purpose of this utility model is to provide a kind of disk drill pipe storage of simple in structure, high efficiency.
This disk drill pipe storage that the utility model provides, comprise center-pole, some drilling rods and two installation components, described center-pole and drilling rod are installed on two installation components, described installation component comprises mount pad, ratchet mechanism, brake, coupling assembling, index dial, safety door, driving cylinder, ratchet mechanism wherein, brake, coupling assembling, index dial is installed on the same main shaft, and ratchet mechanism is connected with main shaft by spline with index dial, be rotatably connected between coupling assembling and the main shaft, ratchet mechanism is articulated and connected by a big connecting rod and mount pad, fixedly connected with coupling assembling in the outer ring of brake, hinged ear in the upper end of coupling assembling and driving cylinder are hinged, hinged ear in lower end and mount pad are hinged, and the other end and the mount pad of driving cylinder are hinged; Safety door comprises and is used to release or regain safety jaw and the safe connecting rod of embracing index dial, the pin joint and the index dial of safety jaw are hinged, another pin joint and safe connecting rod are hinged, the other end and the mount pad of safe connecting rod are hinged, the two ends of described center-pole are fixedly mounted on the index dial center of described two installation components respectively, described drilling rod is distributed in around the center-pole, and is removably mounted on the index dial of described two installation components.
Described ratchet mechanism is totally 4 ratchets, and is uniform by 90 °.
This disk drill pipe storage of the present utility model, only be provided with a group oil cylinder, action by a group oil cylinder, drive whole each the parts interlock of drill pipe storage, easily, finish the action that takes, puts of drilling rod exactly, when having simplified hydraulic system, the accuracy of action location and the simplification of operation have also been guaranteed to take, put.The utility model is simple in structure, greatly reduces labor intensity of operating personnel, has improved operating efficiency and accuracy, reduces the generation of maloperation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged drawing of Figure 1A;
Fig. 3 is the structural representation that the utility model driving cylinder is regained;
Fig. 4 is that the B-B of Fig. 3 is to sectional drawing.
The specific embodiment
From Fig. 1-Fig. 3 as can be seen, this disk drill pipe storage of the present utility model, comprise center-pole 1, some drilling rods 2 and two installation components 3, wherein center-pole 1 and drilling rod 2 are installed on two installation components 3, installation component 3 comprises mount pad 31, ratchet mechanism 32, brake 33, coupling assembling 34, index dial 35, safety door 36, driving cylinder 37, wherein ratchet mechanism 32, brake 33, coupling assembling 34, index dial 35 are installed on the same main shaft, ratchet mechanism 32 has 4 ratchets, and is uniform by 90 °.Ratchet mechanism 32 is connected with main shaft by spline with index dial 35, be rotatably connected between coupling assembling 34 and the main shaft, ratchet mechanism 32 is articulated and connected by a big connecting rod 38 and mount pad 31, fixedly connected with coupling assembling 34 in the outer ring of brake 33, inner ring is connected with main shaft, adopts friction plate to add the disk spring structure and brakes.Hinged ear in the upper end of coupling assembling 34 and driving cylinder 37 are hinged, hinged ear in lower end and mount pad 31 are hinged, the other end of driving cylinder 37 and mount pad 31 are hinged, safety door 36 comprises safety jaw 361 and safe connecting rod 362, the pin joint and the index dial 35 of safety jaw 361 are hinged, another pin joint and safe connecting rod 362 are hinged, and the other end of safe connecting rod and mount pad 31 are hinged.When driving cylinder 37 stretched out or regains, safety jaw 361 can be released or regain and embrace index dial.The two ends of center-pole 1 are fixedly mounted on the center of the index dial 35 of described two installation components respectively, described drilling rod 2 is distributed in around the center-pole 1, and be removably mounted on the index dial 35 of described two installation components 3, drive the center-pole that the elasticity drill rod grip device is housed on the main shaft and be rotated.
Frame, ratchet mechanism 32, big connecting rod 38 are formed parallel-crank mechanism.As shown in Figure 2, in the process that driving cylinder stretches out, ratchet mechanism start-stop action usefulness has overcome the frictional force that is in the brake of same spline segment on the main shaft, makes main shaft keep static relatively with respect to mount pad, but is rotated in the forward 90 ° with respect to coupling assembling.After driving cylinder all stretched out, parallel-crank mechanism rotated 95 °.
As shown in Figure 3, when driving cylinder was regained, brake worked, and the maintenance main shaft is static with respect to coupling assembling, but with respect to 95 ° of mount pad reverse rotations.Stretch out and regain the difference that there are 5 ° in the process rotational angle, utilize the idle stroke of ratchet mechanism to eliminate.
Therefore, driving cylinder is whenever finished a flexible stroke, and main shaft drives center-pole with respect to the coupling assembling half-twist, finishes the transposition of drilling rod position on the index dial.
As shown in Figure 4,4 breach of the corresponding drill pipe diameter of index dial are provided with 2 groups of shell fragments 39 respectively, utilize the elastic force of shell fragment, and the drilling rod chucking is fixing, guarantee that it can not.
