Description

Technical Field

[0001] The utility model relates to the technical field of directional drilling construction, in particular to a horizontal elevation control device for directional drilling construction. Background Technique

[0002] At present, before the construction of a directional drill, it is necessary to use a laser level to mark the elevation of the construction position of the directional drill. The laser level emits laser light to the standard construction position, and then the directional drill constructs along the height position located by the laser light.

[0003] In some complex geological environments, such as environments with rich changes in formation hardness, conventional elevation control devices cannot ensure the horizontality of the laser level and cannot adapt to the positioning in such complex situations. In directional drilling construction, especially when laying underground pipelines, optical cables and other tasks, the construction accuracy is extremely critical. The uneven ground environment makes the traditional elevation control method have certain errors. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a horizontal elevation control device for directional drilling construction, which can ensure the stable positioning of the laser level while ensuring the horizontal stability of the laser level and improving the accuracy of the horizontal elevation.

[0005] The technical solution of the utility model is as follows:

[0006] A horizontal elevation control device for directional drilling construction includes a plurality of adjustable positioning feet, a base, a base table, a horizontal adjustment frame and a horizontal elevation instrument. The plurality of adjustable positioning feet are connected to the bottom end of the base to support the base, and the base table is slidably connected to the upper end surface of the base;

[0007] The horizontal adjustment frame includes a vertical support rod, an angle adjustment turntable, a U-shaped frame and two pitch adjustment turntables. The bottom end of the vertical support rod is fixedly connected to the base table. The angle adjustment turntable is vertically arranged and its turntable base is fixed to the top of the vertical support rod. The U-shaped frame is horizontally arranged, and the middle part of the U-shaped frame is fixedly connected to the turntable of the angle adjustment turntable. The two pitch adjustment turntables are both vertically arranged, and the turntable bases of the two pitch adjustment turntables are respectively connected to the two ends of the U-shaped frame and the two pitch adjustment turntables are parallel and opposite to each other;

[0008] The horizontal elevation instrument includes a laser level. The laser level is vertically arranged between the two ends of the U-shaped frame and is respectively fixedly connected to the turntables of the two pitch adjustment turntables on both sides.

[0009] The described base includes two horizontally arranged and parallel strip sleepers. At both ends of each strip sleeper, an adjustable positioning support leg is connected. On the top of each strip sleeper, two horizontal sliding grooves are provided. The base platform is of a rectangular plate structure. At the bottom of the base platform and near the two longitudinal edges, a longitudinal support beam is fixedly connected. At the bottom of each longitudinal support beam and near both ends, a limit slider is connected. Each limit slider is embedded in a corresponding horizontal sliding groove of the strip sleeper.

[0010] The described vertical support rod is connected to the edge of the base platform and is directly above one of the strip sleepers at the rear.

[0011] The limit slider is in frictional contact with the groove wall of the horizontal sliding groove.

[0012] The described adjustable positioning support leg includes a limit support plate, a telescopic sleeve, and an inverted conical plug. The upper part of the telescopic sleeve is a fixed tube, and the lower part is a movable tube. The fixed tube and the movable tube are nested with each other and are locked and connected by a positioning pin. The limit support plate is horizontally arranged. The bottom end of the telescopic sleeve and the top end of the inverted conical plug are fixedly connected to the limit support plate. The top end of the telescopic sleeve is fixedly connected to the bottom end of the base.

[0013] The described horizontal level gauge further includes a housing. The front end of the housing is of an open structure.

[0014] Advantages of the present utility model:

[0015] (1). The inverted conical plugs of the four adjustable positioning support legs of the present utility model can be stably inserted into the lower part of the designated ground. The limit support plate contacts the ground, increasing the force-bearing surface, and is suitable for soft muddy ground. Since the ground heights at different positions are different, the levelness of the base can be initially adjusted through the telescopic sleeve.

[0016] (2). The base platform of the present utility model can be horizontally and transversely slidably adjusted along the base to achieve fine adjustment of the position of the laser marking instrument and improve the construction accuracy.

The horizontal adjustment frame of the present utility model includes an angle adjustment turntable and two pitch adjustment turntables, which can achieve the pitch adjustment of the laser marking instrument, so that the front end face of the laser marking instrument always remains vertical, that is, the laser emitted by the laser marking instrument remains horizontal. Moreover, a gravity counterweight ball is fixedly connected to the bottom of the horizontal level gauge, and the center of the gravity counterweight ball coincides with the center of gravity of the horizontal adjustment frame. When the present utility model is installed on the ground with rich changes in formation hardness, it can automatically maintain the horizontal stability of the laser marking instrument and improve the construction accuracy.
