Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a device for reducing the deflection rate of geological drilling holes. Background Art

[0002] In the process of geological exploration, it is necessary to obtain the specific stratification of the bottom layer by drilling. The existing geological drilling method is generally performed by drilling with a drilling machine. Due to the different compositions of geological rock strata, the drill bit is subjected to greater resistance during the use of the drilling machine, which will cause the drill bit to deflect, which will not only cause the drilled hole to tilt, but also cause damage to the drill bit. Therefore, the existing drilling equipment will use an anti-deflection device to prevent the drill bit from tilting;

[0003] For example, patent application No. 202021025928.2 discloses a drilling anti-deflection device, which forms a receiving cavity through a V-shaped groove on two clamping blocks. When the drill rod rotates and descends, the two clamping blocks will be in close contact with the surface of the drill rod under the action of their respective springs, and the vibration generated by the drill rod during the drilling process will be transmitted to the clamping blocks. At this time, the spring deforms to buffer the vibration, which can play a certain anti-deflection role;

[0004] This patent in the prior art limits the drill rod by two clamping blocks, but the two clamping blocks can only move elastically in two directions, and the deflection of the drill rod is uncertain, so the anti-deflection device in the prior art has poor stability. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device for reducing the deflection rate of geological drilling holes, so as to solve the problem of poor stability of the anti-deflection device of the drill rod in the prior art described in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a device for reducing the deflection rate of geological drilling, comprising

[0007] Positioning sleeve;

[0008] A rotating sleeve, rotatably disposed on the inner wall of the positioning sleeve;

[0009] A stopper sleeve is located inside the rotating sleeve, and the outer wall of the stopper sleeve is fixedly connected to the inner wall of the rotating sleeve through a plurality of springs;

[0010] A plurality of installation sleeves, which penetrate through the positioning sleeve and are fixedly connected to the positioning sleeve;

[0011] A plurality of laser rangefinders are fixedly connected to the position of the mounting sleeve directly opposite to the stop sleeve;

[0012] A plurality of mounting plates fixedly connected to the outer side wall of the positioning sleeve;

[0013] A plurality of baffles are movably arranged on a plurality of mounting plates.

[0014] Preferably, the inner circumferential wall of the positioning sleeve is provided with a rotation groove, the outer circumferential wall of the rotation sleeve is provided with a guide rail, and the guide rail is rotatably arranged in the rotation groove.

[0015] Preferably, the outer side wall of the retaining sleeve is in the shape of a polygonal column, and a plurality of the springs are respectively fixed on the prism surface of the retaining sleeve.

[0016] Preferably: a buffer plate is fixedly connected to the baffle plate via a plurality of damping springs.

[0017] Preferably: a movable cylinder is fixedly connected to the mounting plate, and an output end of the movable cylinder is fixedly connected to the baffle.

[0018] Preferably, a screw rod penetrating the mounting plate is threadedly connected to the mounting plate, and the screw rod is rotatably connected to the baffle plate.

[0019] The beneficial effects of adopting the above technical solution are:

[0020] The block sleeve provided in the present application can be used for the rotation of the drill rod, and the block sleeve and the rotating sleeve are fixedly connected by a spring, which enables the block sleeve to limit its position through the spring when subjected to the force of the drill rod, thereby limiting the range of motion of the block sleeve. The limit on the block sleeve in the present application is a 360-degree elastic limit, which is more stable than the elastic limit in two directions in the prior art. At the same time, the baffle can further limit the position of the drill rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Positioning sleeve 10;

[0036] This embodiment is implemented as follows:

[0037] When the present application is in use, the drill rod is passed through the stop sleeve 30, which can block the deflection of the drill rod to a certain extent. This blocking method is not restricted by direction and can achieve 360-degree restriction. The spring 40 can limit the moving distance of the stop sleeve 30, thereby preventing the drill rod from deflecting, and the baffle 60 can further restrict the drill rod.

[0038] The advantage of the present application over the prior art is that it can provide a better deflection relief effect.

[0039] See also Figure 2 , 3 The inner circumferential wall of the positioning sleeve 51 is provided with a rotation groove, and the outer circumferential wall of the rotating sleeve 20 is provided with a guide rail, and the guide rail is rotatably arranged in the rotation groove;

[0042] The spring 40 can be installed by the prismatic surface on the stopper sleeve 30 , so that the installation of the spring 40 is more stable.

[0043] See also Figure 4 , a buffer plate 64 is fixedly connected to the baffle plate 60 via a plurality of damping springs 63;

[0044] By providing the damping spring 63 , the buffer plate 64 can be brought into contact with the drill rod first, thereby providing a buffer to the drill rod first.

[0045] See also Figure 1 , 3 , a moving cylinder 61 is fixedly connected to the mounting plate 62, and an output end of the moving cylinder 61 is fixedly connected to the baffle 60;

[0046] The movable cylinder 61 can drive the baffle 60 to move, thereby adjusting the distance between the baffle 60 and the drill rod.

[0047] See also Figure 5 The mounting plate 62 is threadedly connected with a screw 65 that penetrates the mounting plate 62 , and the screw 65 is rotatably connected to the baffle 60 ;

[0048] The rotation of the screw rod 65 can move on the mounting plate 62 , thereby driving the baffle plate 60 to move.

[0049] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
