Embodiment 1

[0023] Embodiment 1 of the present invention provides a hollow drill bit for water-sealed drilling. Hollow drill bits for water-seal drilling, including drilling parts, sleeves and discharge guides; the drilling parts are hollow and arranged at one end of the sleeve and communicated with the sleeve, drilling There are multiple conical teeth on the end surface away from the sleeve, and the tooth width of the conical teeth gradually increases along the direction from the top of the conical tooth to the root of the tooth; the tube wall of the sleeve is provided with a discharge port ; One end of the discharge guide is plugged into the sleeve and the discharge guide has a guide surface to guide the drilled material out of the drill to the discharge port, and the discharge guide and the sleeve are connected by a key to realize synchronous rotation; The other end of the material guide protrudes from the sleeve, and the other end of the discharge guide is provided with a positioning ...

Embodiment 2

[0035] Embodiment 2 of the present invention provides a kind of using method of the hollow drill bit that water seal perforation is used, and this method uses the hollow drill bit that water seal perforation is used as in embodiment one; Using method comprises the steps:

[0036] S01, set one end of the discharge guide in the sleeve and connect with a key to ensure that the two rotate synchronously;

[0037]In this step, connect the discharge guide and the sleeve through a key connection, and adjust the discharge guide surface to a position corresponding to the discharge port;

[0038] S02, the elastic reset member is sleeved on the discharge guide member extending out of the sleeve, and the positioning member is arranged on the discharge guide member;

[0039] In this step, an elastic return member such as a spring is sleeved on the other end of the discharge guide, and the elastic return member is pressed by the positioning member to prevent the elastic return member from de...

Abstract

The invention provides a hollow drill bit for water seal punching and a use method thereof. The hollow drill bit comprises a drilling element, a sleeve and a discharging guide element; a plurality ofconical teeth are arranged on the end surface of the drilling element, away from the sleeve, along the circumferential direction of the drilling element, and the tooth width of each conical tooth is gradually increased along the direction from the tooth top to tooth root of the conical tooth; a discharge port is formed in the pipe wall of the sleeve; one end of the discharging guide element is inserted into the sleeve and the discharging guide element is provided with a guide surface to guide the drill objects to the discharge port, and the discharging guide element and the sleeve are connected through a key connection to achieve synchronous rotation; the other end of the discharging guide element extends out of the sleeve, the other end of the discharging guide element is provided with apositioning element and a connecting part, the discharging guide element is connected with a power device through the connecting part, and an elastic resetting element is arranged between the positioning element and the sleeve. By arranging the drill bit with conical teeth and the discharging guide element, the hollow drill bit can take out and discharge water-sealed rubber.

Description

technical field [0001] The invention relates to the field of maintenance equipment for water conservancy and hydropower projects, in particular to a hollow drill bit for water-seal drilling and a method for using the same. Background technique [0002] For the steel gate of a hydropower station, the water seal is the core component to ensure the water sealing effect of the gate. Since the water seal is a rubber product, it is easy to age after long-term use. Therefore, the hydropower station generally needs to replace the gate water seal every 4-8 years. When sealing, the water seal needs to be drilled for installation. [0003] At present, when drilling the water seal, the general hollow drill bit on the market is mainly used for drilling work. This kind of hollow drill bit has the following convenient defects in the process of use: [0004] 1. Because the material of the water seal rubber is relatively soft, it will expand after friction with the drill bit and generate he...
