Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering investigation, in particular to a geotechnical engineering investigation drilling rig which can prevent deviation. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and preparing investigation documents according to the requirements of the construction project. Investigation drilling rigs are required during the investigation process.

[0003] However, before using the existing exploration drill, it is necessary to move the cylinder moving rod downward and against the ground. However, in actual use, since the exploration drill will generate violent vibrations when working, the cylinder moving rod only rests on the ground. The vibration will cause the exploration drill to shift in position, and then cause the drilling position of the exploration drill to shift, affecting the drilling effect. Utility Model Content

[0004] The utility model aims to provide a geotechnical engineering survey drill rig which is anti-deviation, so as to solve the problem that vibration may cause position deviation of the survey drill rig proposed in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a geotechnical engineering survey drilling rig with anti-deviation, comprising:

[0006] A drilling rig body, wherein the four corners of the drilling rig body are equipped with anti-drifting components, and the outer wall of the drilling rig body is provided with an emergency brake component;

[0007] An anti-deviation assembly includes a cylinder moving rod, a screw rod is arranged inside the cylinder moving rod, a guide block is fixedly installed above the screw rod, a nut pair is arranged on the outer wall of the screw rod, a turntable is fixedly connected to the outer wall of the nut pair, and a cone rod is fixedly connected to the bottom of the screw rod.

[0008] Preferably, the emergency brake assembly includes a rotating rod, an internal shaft rod passing through one end of the rotating rod, a fixed rod is fixedly connected to the lower part of the rotating rod near the end of the rotating rod, a sliding rod is inserted into the interior of the rotating rod, a limiting ring is fixedly installed on the outer wall of the sliding rod, a grip rod is fixedly connected to the end of the sliding rod away from the shaft rod, a spring is arranged inside the end of the sliding rod near the shaft rod, and a clamping block is installed on the end of the spring near the drilling rig body.

[0009] Preferably, the cylinder moving rod is fixedly connected to the drilling rig body, and the screw rod is slidably connected to the cylinder moving rod.

[0010] Preferably, the turntable is rotatably connected to the cylinder moving rod, and the shaft rod is fixedly connected to the drilling rig body.

[0011] Preferably, the rotating rod is rotationally connected to the shaft rod, and the sliding rod is slidingly connected to the rotating rod.

[0012] Preferably, the slide bar is provided with a groove corresponding to the clamping block, and the two ends of the spring are fixedly connected to the slide bar and the clamping block respectively.

[0013] Preferably, a side of the clamping block close to the gripping rod is arranged as a curved surface, and a groove is provided on the drilling rig body corresponding to the clamping block.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The new exploration drilling rig is equipped with an anti-deviation component. Before use, the turntable can be rotated, and the turntable drives the nut pair to rotate. The nut pair drives the screw rod to move downward, and the screw rod drives the cone rod to move downward, so that the cone rod is exposed from the cylinder moving rod. The cylinder moving rod is then moved downward to insert the cone rod into the ground. The cone rod limits the main body of the drilling rig. When the exploration drilling rig is working subsequently, it is ensured that the exploration drilling rig will not be offset, thereby ensuring the efficiency of drilling.

[0016] (2) The new exploration drilling rig is equipped with an emergency brake assembly. The movement of the drilling rig body depends on the engine on the drilling rig body. The drilling rig body can only be stopped by manually shutting down the engine. When driving on an uneven road surface, it is difficult for the staff to shut down the engine immediately. The staff can hold the handle by hand. When it is inconvenient to shut down the engine quickly, the staff can hold the handle and pull it outward. The handle drives the slide bar to move. When the slide bar moves, the block is squeezed into the groove of the slide bar. Then the handle is turned downward, and the fixed rod is in contact with the ground. According to the lever principle, the rear wheel of the drilling rig body is lifted, avoiding the inability to stop the movement of the drilling rig body in an emergency, ensuring safety in special circumstances, and improving practicality and functionality.

When the grip rod 36 is pulled outward, the grip rod 36 drives the sliding rod 34 Movement, the curved surface is more convenient. The block 38 is squeezed into the groove of the slide bar 34. A spring 37 is arranged inside the end of the slide bar 34 close to the shaft rod 32. The spring 37 provides elastic force. Under the elastic force of the spring 37, the block 38 can be inserted into the groove of the drilling rig body 01, and the slide bar 34 can be limited so that the slide bar 34 cannot rotate. A block 38 is installed at one end of the spring 37 close to the drilling rig body 01.

When it is inconvenient to quickly shut down the engine, the staff can hold the handle 36 and pull it outward. The handle 36 drives the slide bar 34 to move. When the slide bar 34 moves, the block 38 is squeezed into the groove of the slide bar 34. Then the handle 36 is turned downward, and the fixed rod 33 contacts the ground. According to the lever principle, the rear wheel of the drilling rig body 01 is lifted, and then the engine of the drilling rig body 01 is turned off. After reaching the designated location, the turntable 25 is turned, and the turntable 25 drives the nut pair 24 to rotate. The nut pair 24 drives the screw rod 22 to move downward.
