Abstract
The utility model discloses a taking-out tool for a pre-buried sleeve in a high-speed rail concrete sleeper. The taking-out tool for the pre-buried sleeve in the high-speed rail concrete sleeper is simple in structure, is convenient to use and saves labor and effort. According to the technical scheme, the taking-out tool for the pre-buried sleeve in the high-speed rail concrete sleeper comprises a connecting rod, a drill bit clamp sleeve and a drill bit matched with the drill bit clamp sleeve are arranged at the end of one side of the connecting rod, and a connecting clamp sleeve is arranged at the other side of the connecting rod. The drill bit is made of hard alloy, a plurality of tool bits are evenly distributed on the outer ring of the peripheral section of the end of the drill bit, and four blunt tool bits are evenly distributed on the outer ring of the peripheral section of the end of the drill bit. The taking-out tool for the pre-buried sleeve in the high-speed rail concrete sleeper is reasonable in structure, convenient to use, and capable of effectively improving the construction efficiency and relieving the labor intensity for workers.
Description
Technical field:
The utility model relates to the instrument of high-speed rail construction, particularly a kind of instrument being applicable to the service sleeve taking-up in high ferro concrete crosstie.
Background technology:
Service sleeve in high ferro concrete crosstie is the parts that must use in high-speed rail construction now, this sleeve pipe generally adopts nylon material, but in actual use, because this sleeve pipe often needs dynamic stress, the situation that easily causes sleeve pipe generation stripped thread, and then can cause service sleeve to lose efficacy, this just need to change in time to service sleeve.At present in construction, the most frequently used is exactly to adopt water to bore the service sleeve in concrete crosstie is directly taken out, this form of construction work can be destroyed concrete crosstie, need to re-start location to the installation site of sleeve pipe, increase difficulty of construction, adopt water to bore construction, can make working procedure comparatively numerous and diverse, and need a plurality of workmans to carry out compounding practice just to complete, workman's labour intensity is larger, and efficiency of construction is lower.
Summary of the invention:
The purpose of this utility model is that the service sleeve designing in high ferro concrete crosstie a kind of simple in structure, easy to use, that save labor takes out instrument.
The technical solution of the utility model is, service sleeve in high ferro concrete crosstie takes out an instrument, and it comprises connecting rod, it is characterized in that: the side end at connecting rod is provided with drill bit cutting ferrule, there is a drill bit with drill bit cutting ferrule matches, at the opposite side of connecting rod, be provided with connecting sleeve.Described drill bit is that carbide alloy is made.On the outer ring of the circumferential section of described drill bit end, be evenly equipped with a plurality of cutter heads.On the outer ring of the circumferential section of described drill bit end, be evenly equipped with four blunt knife heads.
The utility model is rational in infrastructure, easy to use, can effectively improve efficiency of construction, reduces workman's labour intensity.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the top view of a kind of drill bit described in the utility model, and Fig. 3 is the lateral view of another kind of drill bit described in the utility model.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail,
Embodiment 2 of the present utility model is, the service sleeve in a kind of high ferro concrete crosstie takes out instrument, and it comprises connecting rod, a side end at connecting rod is provided with drill bit cutting ferrule, have a drill bit with drill bit cutting ferrule matches, at the opposite side of connecting rod, be provided with connecting sleeve, matching with connecting sleeve is electric drill head; Drill bit described in the present embodiment is that carbide alloy is made, and is evenly equipped with four blunt knife heads (drill bit as shown in Figure 2) on the outer ring of the circumferential section of described drill bit end.In use, electric drill and the utility model are fixed by cutting ferrule, then open electric drill, the utility model is stretched in the hole of the service sleeve in high ferro concrete crosstie, because the top of service sleeve is provided with four equidistant grooves, these four grooves are just crosswise and distribute in the top cross-section of service sleeve, four blunt knife heads on corresponding drill bit are also such distributions, use the utility model whole service sleeve can be screwed out in service sleeve hole, whole work progress is simpler, fast, and labour intensity very little.
The utility model structure is comparatively reasonable, operation is very easy, can effectively improve the efficiency of construction of changing the service sleeve in high ferro concrete crosstie, the utility model does not destroy high ferro concrete crosstie, do not need the position of the service sleeve in high ferro concrete crosstie to reorientate yet, reduce construction cost, and greatly reduced workman's labour intensity, the utlity model has good promotion prospect.
