Abstract
The utility model discloses a guide supporting device capable of adjusting the central height of a drill pipe. The guide supporting device capable of adjusting the central height of the drill pipe comprises a sliding way, a sliding frame, an oil cylinder and a rotary sleeve, wherein the sliding way, the sliding frame, the oil cylinder and the rotary sleeve are fixed to a machine frame arranged at the front end of a drilling machine. A circular frame body is arranged at the top of the sliding frame, a plurality of directed idler wheels are clamped by the frame body in the circumferential direction of the frame body, the rotary sleeve is erected in circular space defined by the idler wheels and can rotate, the sliding frame is fixed to the oil cylinder, and the oil cylinder drives the sliding frame to slide along the sliding way in a locating mode. According to the guide supporting device capable of adjusting the central height of the drill pipe, in the operation process, the center of the semicircular rotary sleeve is adjusted through ascending and descending of the hydraulic oil cylinder, the purpose that the center of the drill pipe is adjusted is achieved, the semicircular rotary sleeve is a piece prone to damage, when a plug is pulled out, a movable upper cover is lifted, and the semicircular rotary sleeve can be replaced.
Description
Technical field
The utility model relates to and a kind ofly for horizontal directional drilling machine, regulates drilling rod centre-height, makes the device of the guide support that the centre-height of drilling rod and the centre-height of unit head and clamp be consistent.。
Background technology
In non-excavation directional traversing work progress, often can encounter softer stratum, and the weight of construction drilling tool is heavier, when reaming or trombone slide, reamer or the pipeline drawing can sink, and cause drilling rod center to move down, lower than the center of unit head and clamp.In the time will dismantling drilling rod thread, clamp folder is less than the center of drilling rod, and not clamping drilling rod, unloads the screw thread not spudding between bar.In this case, can only drilling rod be sling by crane, make drilling rod center consistent with unit head and clamp center, can clamp drilling rod, dismantle the screw thread between drilling rod.Both affect programming, increased again construction cost.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of guiding support device of adjustable drilling rod centre-height, makes drilling rod center consistent with unit head and clamp center, is convenient to dismantle the screw thread between drilling rod.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of guiding support device that regulates drilling rod centre-height, comprise the slideway, travelling carriage, oil cylinder and the rotary sleeve that are fixed in rig front end frame, the top of travelling carriage is circular support body, this support body is along circumferentially clamping the roller that has a plurality of orientations, described rotary sleeve is set up in the circular space that a plurality of rollers surround and can rotates, described travelling carriage is fixed on oil cylinder, and oil cylinder drives travelling carriage to slide along described slideway location
Further, described circular support body is divided into upper cover and holder two parts, and described holder and upper cover are flexibly connected.
Further, described oil cylinder is hydraulic jack, is fixed on cylinder support.
Further, between described oil cylinder and travelling carriage, by bearing pin, fix.
Further, described rotary sleeve is semicircle.
Further, described roller is provided with 8.
The technique effect that the utility model reaches is as follows: the guiding support device of adjusting drilling rod centre-height of the present utility model, in the course of the work, utilize rise and the landing of hydraulic jack, adjust the center of semicircle rotary sleeve, reach the object that regulates drilling rod center, semicircle rotary sleeve is consumable accessory, extracts latch, lift movable top lid, replaceable semicircle rotary sleeve.
