Further, the telescopic legs are hinged with the housing.

Further, the shell is a metal shell. The elevation angle of the device can be adjusted by a hinging mode so as to adapt to drilling holes with different elevation angles. The drill rod falling from the running drill enters the device by utilizing the guiding of the rubber cylinder in the device. Through the combined action of rubber tube and spring, play the buffering effect to avoid drilling rod damage and other safety risks.

The utility model has the beneficial effects that: during the use, install this device in the below of drilling rod, the drilling rod runs the drilling and falls into the rubber tube after falling in, and the rubber tube can effectively lead and support the drilling rod, and under the cushioning effect of spring, the impact of falling converts the flexible impact into, can avoid the damage of drilling rod, prevents that the drilling rod from dropping subaerially and injures staff or equipment by a crashing object, has improved the security of construction.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in fig. 1, the running drill anti-collision safety device for upward drilling comprises a shell 1 with an open upper end, a rubber cylinder 2 is arranged in the shell 1, the upper end of the rubber cylinder 2 is open, the inner diameter of the rubber cylinder 2 is gradually reduced from top to bottom, the lower end of the rubber cylinder 2 is conical, a spring 3 is arranged between the outer wall of the rubber cylinder 2 and the bottom of the shell 1, and an installation positioning mechanism is arranged on the outer wall of the shell 1.

The housing 1 is made of a material with high strength, such as a metal material or a plastic material with high strength. The shell 1 is enclosed by a bottom plate and four side plates to form a cavity structure with an open top. Rubber tube 2 is used for the direction and the buffering of drilling rod, and the internal diameter of rubber tube 2 reduces from last to down gradually, and its inner surface has the inclined plane, guarantees good guide effect, can drop to the bottom of rubber tube 2 along the inner wall of rubber tube 2 after the drilling rod falls into in rubber tube 2. The spring 3 is a compression spring, plays the role of buffering and shock absorption, and avoids the drill rod from generating larger rigid impact after falling into the rubber cylinder 2.

The rubber cylinder 2 may be a regular conical cylinder, preferably, the rubber cylinder 2 includes a circular truncated cone section 21, a circular ring section 22 and a conical section 23, and the lower end of the circular truncated cone section 21 is connected with the upper end of the conical section 23 through the circular ring section 22. The circular ring section 22 is horizontally arranged, the upper end of the spring 3 compresses the outer wall of the circular ring section 22, the installation stability of the spring 3 can be improved, and the conical section 23 is located inside the spring 3.

Installation positioning mechanism is including setting up a plurality of hinges 4 in 1 diapire one end of shell, and hinge 4 can be connected with ground through expansion bolts, and shell 1 can rotate round hinge 4 after connecting to adjust the angle of shell 1, make the angle of rubber cylinder 2 and the angle looks adaptation of the drilling of facing upward.

In order to improve the stability of installation, installation positioning mechanism still includes a plurality of telescopic leg 5 of setting at the shell 1 diapire other end, telescopic leg 5 is articulated with shell 1. The telescopic supporting legs 5 adopt the existing telescopic rod structure, and the length can be locked after being extended or shortened.
