Description

Technical Field

[0001] The utility model relates to the technical field of screw rods, in particular to a high-strength screw rod for hydraulic equipment. Background Art

[0002] Screws are commonly used in hydraulic equipment, such as spiral drilling machines. The motor drives the screw to rotate and with the cooperation of hydraulics, the screw is rotated downward to drill holes. The outer surface of the screw is cut with a cylinder with a spiral groove or a cone with a conical spiral groove. The screw has different heads. The head is called an external hexagonal screw. There are others, such as a large flat screw, an internal hexagonal screw, and so on.

[0003] The existing screw rods for hydraulic equipment have the following disadvantages: the screw rods are hollow structures and cannot improve the overall strength, rigidity and stability. Therefore, we propose a high-strength screw rod for hydraulic equipment. Summary of the invention

[0007] Furthermore, one end of the reinforcing column is connected to the arc drill bit by a bolt, and the other end of the reinforcing column is fixed to the end of the screw body by a positioning plate and a screw. The reinforcing column in the hollow cavity is used to improve the strength and rigidity of the screw body, making it durable.

[0008] Furthermore, a triangular ruler is welded on the outer side of the circular drill bit, and the end of the screw body can be directly sleeved by means of a clamp sleeve and a locking bolt, so as to facilitate installation and disassembly.

[0009] Furthermore, a locking bolt is installed on the outer side of the clamp sleeve through a bolt hole.

[0010] Furthermore, a No. 2 shaft sleeve is welded to one side of the enlarged pad B, and an enlarged disk is provided on the outer side of the clamp sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model discloses a high-strength screw for hydraulic equipment. A No. 2 shaft sleeve is used to facilitate connection with a rotating shaft. A steel pad clamped between an enlarged pad A and an enlarged pad B is used to evenly disperse stress during the drilling process of the screw body, thereby improving the stability of the screw body. A reinforcing column in a hollow cavity is used to improve the strength and rigidity of the screw body, thereby making the screw body durable.

[0013] 2. The utility model discloses a high-strength screw for hydraulic equipment. The triangular cutter on the arc drill bit is used to increase the drilling rate of the screw body, thereby improving the construction progress. The clamp sleeve and the locking bolt are used to directly sleeve the end of the screw body, thereby facilitating installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
