Description

ZD6 type goat motor gear extracting tool

Technical Field

The utility model relates to a extracting tool especially relates to a ZD6 type goat motor gear extracting tool.

Background

When the ZD6 type switch machine motor gear is replaced and disassembled at the present stage, common tools such as an iron hammer, a crowbar and a wrench are used for on-site disassembly, and the disassembly mode is easy to damage the gear and internal accessories of the motor. Because the railway transportation operation is busy, a great deal of time is consumed when the motor is disassembled by using a common tool, generally, the time for disassembling the motor is about 30 minutes when the motor is smoothly disassembled, and the field operation requirement is required to be completed in a short time, thereby bringing great difficulty to the field disassembling work. And the motor which is difficult to disassemble needs to be sent to a processing group to utilize a tool assembly to disassemble a motor gear, the distance is repeated, a large amount of time, manpower and material resources are consumed, and particularly, common tools are heavy and are inconvenient to carry and use on site.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ZD6 type goat motor gear extracting tool solves the long-term instrument that does not have the motor gear of being fit for disassembling in the on-the-spot maintenance operation, and the operation in-process is disassembled at equipment easily causes the gear damage, and personnel's potential safety hazard, the utility model discloses can in time solve the on-the-spot motor and disassemble the maintenance operation, labour saving and time saving greatly alleviates staff's intensity of labour, guarantees personnel and equipment safety.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a ZD6 type switch machine gear extracting tool, including the fastener, screw knockout pin, hand grip;

fastener one end is lateral part open-ended hollow structure and the bottom plate of this tip is U type breach steel sheet, fastener other end threaded connection has the screw ejector pin, screw ejector pin one end is followed the axial central line spiral of fastener stretches into just extend to in the fastener U type breach steel sheet, the other end of screw ejector pin be used for with handle adaptation joint is so that pass through the handle is rotatory the screw ejector pin.

Furthermore, the fastener is a cylindrical cylinder sleeve with the length of 10cm and the diameter of 7cm, and the length of the hollow structure is 7 cm.

Further, the handle is a wrench.

Furthermore, the screw ejector rod is a hexagonal screw ejector rod.

Furthermore, a thread section is arranged in one end, deviating from the bottom plate, of the fastener and is used for being in thread fit with the screw ejector rod.

Furthermore, the thread section of the fastener is welded and butted with a hexagon nut matched with the thread section, and the screw ejector rod sequentially penetrates through the hexagon nut and the thread section to extend into the fastener.

Compared with the prior art, the utility model discloses a beneficial technological effect:

(1) the utility model is portable, simple and reasonable in structure, light and small, high in strength and firm in clamping;

(2) the utility model discloses easy and simple to handle, easy to get on hand, 4 ~ 5 minutes alright once only pull down the gear, solve the on-the-spot maintenance operation and be difficult to the operation, avoid going to and fro on the distance futilely, labour saving and time saving alleviates staff intensity of labour. The fastener is not easy to fall off after being locked, and is safe and reliable; the disassembly and assembly can be rapidly completed on site, the potential safety hazard is eliminated, and a large amount of time, labor and material resources are saved.

(3) The utility model discloses not only can dismantle the gear, be applicable to long 7 centimeters main shaft and accessory dismantlements within the scope moreover.

Detailed Description

As shown in fig. 1 to 3, a ZD6 type switch machine gear dismounting tool comprises a fastener 1, a hexagonal screw top rod 2 and a handle 3;

the bottom plate that 1 one end of fastener is lateral part open-ended hollow structure and this tip is U type

breach steel sheet

5, 1 other end threaded connection of fastener has hexagonal

screw ejector pin

2, 2 one ends of hexagonal screw ejector pin are followed the axial direction line spiral of fastener 1 stretches into in the fastener 1 and to U type breach steel sheet 5 extends, the other end of hexagonal screw ejector pin 2 be used for with 3 adaptation joints of handle are so that pass through 3 rotations of handle hexagonal screw ejector pin 2.

The fastener 1 is a cylindrical cylinder sleeve with the length of 10cm and the diameter of 7cm, and the length of the hollow structure is 7 cm. The handle 3 is a wrench. And a thread section 6 is arranged in one end of the fastener 1, which deviates from the bottom plate, and is used for being in thread fit with the hexagonal screw ejector rod 2.
