Technical Field
The invention relates to the technical field of railway track appliances, in particular to a turnout eccentric sleeve extractor.
Background
The existing GLC turnout long sleeper embedded ballastless track bed structure concrete sleeper eccentric sleeve of the high-speed railway is a component which must be used in high-speed railway construction. In actual use, due to the change of the track gauge direction of the line, the eccentric sleeve needs to be replaced frequently, so that the track gauge and the direction of the line can be adjusted, and the requirement of high smoothness of the line can be met.
The eccentric cover generally adopts the nylon material, and at present in the maintenance of daily maintenance, the most common use is exactly to adopt tools such as crowbar, sledge hammer, chisel to take out the eccentric cover in the concrete pillow, and the traditional mode of operation degree of difficulty is big, and the process is comparatively numerous and diverse, needs a plurality of workman to carry out the cooperation operation just can accomplish, and it is great to cause workman's intensity of labour, and the efficiency of construction is lower, and the maintenance is artifical and material cost is higher.
The patent publication No. CN105200875B discloses a multifunctional extractor for GLC turnout eccentric bushing, which comprises a screw rod/a screw rod, a drawing part in transmission fit with the screw rod/the screw rod, a lifting part in transmission fit with the screw rod/the screw rod, and a support frame which forms circumferential positioning with the lifting part and forms a support structure for the screw rod/the screw rod, wherein a plurality of expansion wires are arranged at the end part of the lifting part matched with the eccentric bushing, the end part of each expansion wire is provided with a flange-shaped clamping protrusion protruding out of the outer edge of the expansion wire, and the drawing part is in running fit with the corresponding support frame.
When the technical scheme is used in practice, the inventor finds that the purposes of saving labor and improving the construction efficiency can be achieved by using the technical scheme, but the technical scheme is complex in structure and high in manufacturing cost, is large in size and is inconvenient to carry, operation steps are still complex during use, and further optimization operation is needed.
Disclosure of Invention
The invention aims to provide a turnout eccentric sleeve extractor, and aims to solve the problems that the turnout eccentric sleeve extractor in the prior art is complex in structure, high in manufacturing cost, inconvenient to carry due to large volume and complicated in operation steps during use.
In order to achieve the purpose, the invention adopts the following technical scheme: the turnout eccentric sleeve extractor comprises a straight rod; the bayonet lock is arranged at the bottom of the straight rod and can be clamped into the groove of the eccentric sleeve; the impact piece moves along the straight rod in a single degree of freedom; and the impact piece is arranged on the straight rod and can be impacted by the impact piece.
The invention further adopts the technical scheme that the automobile bumper further comprises a pull ring arranged on the impact piece.
According to a further technical scheme, the shock absorber further comprises a limiting piece arranged on the straight rod, and the limiting piece is located between the shock piece and the clamping pin.
According to the further technical scheme, the limiting piece is in a ring shape.
According to the further technical scheme, the cross section of the straight rod is circular, regular polygon or oval, and the impact piece is sleeved on the straight rod.
According to the further technical scheme, the impact piece is in a hollow cylindrical shape.
According to the further technical scheme, friction grains are arranged on the surface of the impact piece.
According to the further technical scheme, the impact piece is made of metal.
The invention has the beneficial effects that:
1. when the turnout eccentric sleeve needs to be taken out, the straight rod can be directly inserted into the turnout eccentric sleeve, the bayonet lock is clamped into the groove of the turnout eccentric sleeve, then an operator holds the straight rod with one hand and moves the impact piece upwards with the other hand to enable the impact piece to impact the impact piece, so that the impact piece and the straight rod are subjected to an instantaneous upward impact force, the turnout eccentric sleeve is more easily separated from a clamping installation state with the installation groove under the driving of the impact force, the turnout eccentric sleeve is loosened in the installation groove, and the turnout eccentric sleeve can be easily taken out at the moment;
2. the invention skillfully adopts instant impact force to realize the loosening of the turnout eccentric sleeve, greatly reduces the labor intensity of an operator and also improves the construction efficiency;
3. the portable multifunctional electric water heater is simple in structure, low in manufacturing cost, small in size, quite suitable for carrying, and beneficial to popularization and use in the industry, and meanwhile, more advantages are achieved.
Drawings
Figure 1 is a perspective view of a particular embodiment of a switch eccentric bushing extractor.
