Abstract
The utility model discloses a conversion joint for the production of anchor rods, which comprises a threaded connection body I, a transition handle, a threaded connection body II and a protection sleeve. The conversion joint is made of high-carbon steel and has the advantages of good strength and strong anti-impact resistance. The conversion joint is suitable for the production of anchor rods.
Description
Technical field
The utility model relates to a kind of crossover sub, refers in particular to a kind of crossover sub that anchor pole is produced that is used for.
Background technique
Along with the increasing of infrastructure construction dynamics such as traffic, the energy, in tunnel, basement and side slope, developed rapidly as the anchorage technology that can give full play to the rock mass self-stable ability, the rock bolt consumption grows with each passing day, and demonstrates vast potential for future development.Suspension roof support is a kind of most economical effective method that improves Geotechnical Engineering stability.
Wherein, the reliable in quality of hollow bolt, anchoring effect and reinforcement effect are far superior, and its application is more and more wider.The hollow bolt system can guarantee that slip casting is full between anchor rod body and hole wall, gives full play to the anchoring effect of anchor pole.Behind the rock mass excavation, supporting power (supporting plate power or prestressing force) can be provided immediately, protect the inherent strength of rock mass effectively, stop the loosening and distortion of country rock, strengthen the stability of Geotechnical Engineering.Its body of rod has enough slurries parcels, has improved the ability of opposing corrosion greatly, demonstrates favorable durability.It can avoid or extenuate the generation of landslide roof fall accident and other engineering disease, and durability is remarkable, has long-term recessive economic benefit.
The crossover sub device that is absolutely necessary in the manufacturing mechanism of anchor pole, the crossover sub that has in the existing technology has satisfied not requirement.
Summary of the invention
The utility model purpose is to provide a kind of crossover sub that anchor pole is produced that is used for.
The technical solution of the utility model is: comprise the body I that is threaded, transition handle, be threaded body II and protecting jacket, the described body I that is threaded is connected by the transition handle with protecting jacket, and protecting jacket is installed on outside the body II that is threaded.
The utility model part adopts high carbon steel to process, and intensity is good, and anti-impact force is strong, is suitable for the production of anchor pole.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, the body I that is threaded; 2, transition handle; 3, the body II that is threaded; 4, protecting jacket.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The utility model comprises the body I (1) that is threaded, transition handle (2), body II (3) and protecting jacket (4) are threaded; The described body I (1) that is threaded is connected by transition handle (2) with protecting jacket (4), and protecting jacket (4) is installed on outside the body II (3) that is threaded.
The utility model part adopts high carbon steel to process, and intensity is good, and anti-impact force is strong, is suitable for the production of anchor pole.
Claims (2)
1. one kind is used for the crossover sub that anchor pole is produced; It is characterized in that; Comprise the body I (1) that is threaded, transition handle (2), body II (3) and protecting jacket (4) are threaded; The described body I (1) that is threaded is connected by transition handle (2) with protecting jacket (4), and protecting jacket (4) is installed on outside the body II (3) that is threaded.
2. crossover sub as claimed in claim 1 is characterized in that, is processed by high carbon steel.
