Description

Electric flat pin clamp

Technical Field

The utility model belongs to the technical field of the rail vehicle maintenance, a electronic flat pin clamp is related to.

Background

The bogie is generally composed of a framework, wheel pairs, axle boxes, spring damping devices, a swing bolster, a brake mechanism and the like, and is an important supporting, damping and traveling mechanism of the railway vehicle. The conventional bogie mainly depends on the split flat pin for connecting and positioning a plurality of components, the split flat pin is mainly composed of a pin head 101 in an arc shape and a pin tail 102 in a linear shape as shown in fig. 1, and the using method is the same as that of the conventional split pin, and the pin tail 102 is bent towards two sides after being inserted into a corresponding pin hole so as to avoid falling out of the pin hole. However, the split flat pin used in the railway bogie is mainly formed by bending flat iron, the overall structural strength is high, and the flat iron has high toughness, so that when the bogie needs to be disassembled and maintained, the split flat pin cannot be disassembled by adopting a conventional split pin disassembling method. Adopt the gas cutting method just need on-spot flammable explosive gases such as oxygen cylinder and acetylene cylinder of use, not only have great potential safety hazard, the transportation and the transport of oxygen cylinder and acetylene cylinder are also very inconvenient moreover, simultaneously, use the gas cutting still to produce a large amount of carbon dioxide, do not conform to the environmental protection policy of national energy-saving carbon reduction.

SUMMERY OF THE UTILITY MODEL

The utility model provides an electronic flat pin clamp to solve the problem that the use that prior art exists is inconvenient, contaminated air and potential safety hazard are big.

The technical scheme of the utility model is that: the utility model provides an electronic flat pin clamp, is including the main part of installing electronic jar, and the handle is installed to the lower part of main part, is fixed with the connecting seat that extends towards the place ahead at the cylinder front end of electronic jar, is equipped with the fixed work end corresponding with electronic jar piston rod on this connecting seat fixed work end is equipped with relative parallel and extrusion fit's extrusion plane respectively with the front end of electronic jar piston rod.

The bottom of the handle is connected with a battery, and the front part of the handle is provided with a control switch for controlling the on-off of a circuit between the battery and the electric cylinder.

The connecting seat and the fixed working end are integrated to form a U-shaped structure.

By adopting the technical scheme, the beneficial effects of the utility model are that: utilize electronic jar to flatten round pin head and can easily dismantle the opening cotter pin from the pinhole, have overall structure simple, convenient characteristics safe in utilization, effectively solved the inconvenient, air pollution and the big problem of potential safety hazard of use that prior art exists.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an electronic cotter clamp's is concrete as shown in figure 1, it is including installing electronic jar main part 1, handle 2 is installed to main part 1's lower part, be fixed with towards the connecting seat 5 that the place ahead extends at 3 front ends of electronic jar cylinder, be equipped with on this connecting seat 5 with the corresponding fixed work end 6 of electronic jar piston rod 4, this fixed work end 6 constitutes with connecting seat 5 an organic whole, wholly enclose into the U-shaped structure, movable compact heap is installed to the preceding tip at electronic jar piston rod 4, install on the fixed work end 6 of connecting seat 5 and correspond complex fixed compact heap with movable compact heap, be equipped with relative parallel and extrusion fit's extrusion plane on movable compact heap and fixed compact heap respectively. In order to further facilitate the use of the electric flat pin clamp in the scene that an external power supply is difficult, in the embodiment, the bottom of the handle 2 is also connected with a battery 7, and meanwhile, the front part of the handle 2 is provided with a control switch 8 for controlling the on-off of a circuit between the battery 7 and the electric cylinder.

The utility model discloses an electronic cotter clamp when using, only need place the round pin head 101 of opening cotter in between the fixed work end 6 of electronic cylinder piston rod 4 and connecting seat 5, start electronic cylinder work through control switch 8, can press from both sides the round pin head 101 of opening cotter through the relative complex extrusion plane between electronic cylinder piston rod 4 and the fixed work end 6 flat to light take out the opening cotter from the pinhole. The utility model discloses an electronic flat pin clamp overall structure is simple, is applicable to the job scene of multiple difference, and convenience safe in utilization has effectively solved the problem that prior art exists.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
