Description

Technical Field

[0001] The utility model belongs to the technical field of braking devices, and in particular relates to a braking device of a crawler type hydraulic drilling rig. Background Art

[0002] Hydraulic drilling rig is also called oil hydraulic drilling rig. It is a kind of rotary drilling rig commonly produced in my country. The main types are rotary drilling rig, impact drilling rig and compound drilling rig. This type of drilling rig uses diamond, carbide, drill grain drill bits and fishtail drill bits, etc. It can perform core drilling and full-hole drilling without core drilling, and can also be used for impact drilling with a winch.

[0003] For example, the Chinese patent with the publication number CN213870833U proposes a braking device for a crawler hydraulic drill for mining, which includes a transmission box, an end cover, a rotating shaft and a disc spring. A accommodating chamber is provided on the left side of the transmission box, and the right side and the lower side of the accommodating chamber are the main transmission parts of the transmission box. The transmission box is provided with an oil inlet hole and an oil return hole, and the rotating shaft is rotatably connected with the transmission box. A protrusion is provided at the left end of the rotating shaft, and an adjustment section is provided at the right end of the rotating shaft. The adjustment section is connected with a nut through a thread. The disc spring is passed through the rotating shaft, and the left end of the disc spring contacts the protrusion, and the right end of the disc spring contacts the box wall of the transmission box. The right side of the protrusion and the left side of the box wall are both provided with a wear-resistant layer, and the end cover is connected with the transmission box. The utility model solves the problem that the crawler hydraulic drill has a narrow application range in mineral resource mining due to the unreasonable design position of the braking device in the prior art, and is suitable for crawler hydraulic drills;

[0004] However, in the actual application of this solution, if the braking device in the power mechanism is accidentally damaged after long-term use, the rotating wheel cannot be braked, resulting in the crawler hydraulic drill being able to brake when rising and falling, thereby affecting the normal working speed. In order to solve the above problem, we propose a braking device for the crawler hydraulic drill. Utility Model Content
