Description
Technical field
The utility model is related to a kind of weight pin removals, belong to water turbine set maintenance tool technical field.
Background technology
Hydraulic power plant generally uses vertical Francis formula turbine-generator units.The responsibility of machinery class of maintenance portion is just responsible for
Unit maintenance is safeguarded and installation task.Due to vertical Francis formula turbine-generator units, part hydraulic turbine component belongs to burying part
Need long period of soaking underwater so that pin easily generates corrosion.The difficulty for pulling out pin and time are considerably increased, is seriously affected
The repair schedule of unit.Nail tool originally pull pin as shown in the following diagram, intermediate dead man nut alignment pins position and with pin
The connection of oncomelania tooth is fixed, then a jack is respectively put below balancing pole both ends, and two people up to be pushed up together with jack, are being made
It wants both ends jack balance that can just pin be made effectively to extract during industry, can not pulled out if force unbalance will block pin
Come, it is serious also pin to be caused to deform.And this method is by the restricted larger of space.
Utility model content
To solve technical problem of the existing technology, the utility model provides a kind of simple in structure, easy to use, side
Just it is quickly pulled pin, the high weight pin removal of working efficiency.
To achieve the above object, technical solution is weight pin removal used by the utility model, described including connecting rod
The bottom of connecting rod is equipped with connector sleeve, and connector is equipped in the connector sleeve, and the connector sleeve and connector pass through axis pin
Connection is equipped with limited block at the top of the connecting rod, is slidably fitted with clump weight in the connecting rod, and the two of the clump weight
Side is also equipped with ear mount, and operation handrail is equipped in the ear mount.
Preferably, electric driving mechanism is also equipped on the clump weight, the electric driving mechanism includes screw, fixation
Plate, driving motor, the both sides of the clump weight are provided with threaded hole, screw, the bottom of the screw are equipped in the threaded hole
Portion is equipped with cushion block by pressure bearing, and fixed plate is fixed at the top of the screw, and driving electricity is equipped in the fixed plate
Machine, driving motor are connect with screw, and sprocket wheel is equipped in the middle part of the screw, and the sprocket wheel is connected by chain.
Preferably, it is additionally provided with the through-hole passed through for connecting rod in the middle part of the fixed plate.
Compared with prior art, the utility model has following technique effect：The utility model is simple in structure, and design is closed
Reason using directly counterweight is installed in connecting rod, is moved upwards using counterweight and pulls pin or pulled out using motor drive
Pin, it is easy to operate, working efficiency is effectively increased, reduces the amount of labour of staff, shortens the maintenance duration of unit.And
And connector can be replaced according to the size and shape pulled pin.
Description of the drawings
Fig. 1 is the structure diagram of embodiment one in the utility model.
Fig. 2 is the structure diagram of embodiment two in the utility model.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and advantageous effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, the present invention is further described in detail.It should be appreciated that specific reality described herein
It applies example to be only used to explain the utility model, is not used to limit the utility model.
Embodiment one
As shown in Figure 1, weight pin removal, including connecting rod 1, the bottom of connecting rod 1 is equipped with connector sleeve 2, in connector sleeve 2
Connector 3 is installed, connector sleeve 2 and connector 3 are connected by axis pin 4, and the top of connecting rod 1 is equipped with limited block 5, connecting rod
Clump weight 6 is slidably fitted on 1, the both sides of clump weight 6 are also equipped with ear mount 7, and operation handrail 8 is equipped in ear mount 7.
When in use, connecting rod is connected with pin by connector, connector can be according to the pattern of pin and straight
Diameter is made, and then by lifting operation handrail upwards, makes counterweight slamming down limited block, upward to my connecting rod one
Active force plays the purpose pulled pin.
Embodiment two
As shown in Fig. 2, weight pin removal, including connecting rod 1, the bottom of connecting rod 1 is equipped with connector sleeve 2, in connector sleeve 2
Connector 3 is installed, connector sleeve 2 and connector 3 are connected by axis pin 4, and the top of connecting rod 1 is equipped with limited block 5, connecting rod
Clump weight 6 is slidably fitted on 1, the both sides of clump weight 6 are also equipped with ear mount 7, and operation handrail 8 is equipped in ear mount 7.Clump weight
It is also equipped with electric driving mechanism on 6, electric driving mechanism includes screw 9, fixed plate 10, driving motor 11, and the two of clump weight 6
Side is provided with threaded hole, and screw 9 is equipped in threaded hole, and the bottom of screw 9 is equipped with cushion block 13, screw by pressure bearing 12
9 top is fixed with fixed plate 10, and the middle part of fixed plate 10 is additionally provided with the through-hole 16 passed through for connecting rod, in fixed plate 10
Driving motor 11 is installed, driving motor 11 is connect with screw 9, and the middle part of screw 9 is equipped with sprocket wheel 14, and sprocket wheel 14 passes through chain
15 are connected.
The present embodiment is identical with the principle of embodiment one, with electric driving mechanism is re-mounted, when being pulled pin, connects
Then good connector drives two screws to rotate synchronously using motor, screw is connected by sprocket wheel, chain, and then is realized and synchronized
Rotation, then in screw rotation process, gives clump weight one upward active force, connecting rod is promoted to move up, reaches and pulls out
The purpose of pin.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should all wrap in the utility model model
In enclosing.
