In the structure of a hydropower station factory bridge crane, a plurality of components connected by pin shafts, such as a travelling mechanism, a movable pulley, a fixed pulley and other structural components, exist, and the structural components need to penetrate and withdraw shafts from shaft holes in the installation and later overhaul of the bridge crane. At present, the main methods for the pin shaft of these components to penetrate and withdraw are: the copper bar pad is held by one person at one end of the pin shaft by matching two workers, the copper bar is knocked by one person by using the sledge hammer, and the pin shaft is knocked in or out of the shaft hole by the knocking force of the sledge hammer so as to achieve the purpose of penetrating into and withdrawing from the pin shaft.
The existing hydropower station bridge engine pin shaft penetrating and withdrawing mode has the following adverse conditions:
1. the knocking by the sledgehammer has certain safety risk, and if the knocking is not aligned, a person holding the copper bar is easy to be injured by crashing;
2. the bearing is vibrated and impacted by knocking, and the bearing can be damaged by improper operation;
3. the condition of uneven stress exists in knocking, the shaft is easily blocked in the shaft hole, and the working efficiency is affected.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a bridge crane walking wheel round pin axle dismouting device for there is the potential safety hazard, damages the bearing and influences work efficiency's problem in the dismantlement mode of solving current round pin axle of knocking.
In order to solve the above problem, the to-be-solved technical scheme of the utility model is:
the utility model provides a bridge crane walking wheel round pin axle dismouting device, includes pull rod, hydraulic pressure elongator, crown plate, manual hydraulic pump and a plurality of bush, and fixed connection is at the blind plate of pull rod one end through a plurality of screws and walking wheel round pin axle fixed connection, and hydraulic pressure elongator, crown plate and a plurality of bush overcoat are outside the pull rod in proper order, and the pull rod exposes hydraulic pressure elongator one end and nut threaded connection, and manual hydraulic pump passes through hydraulic pressure pipe switch-on hydraulic pressure elongator.
The blind plate external diameter is the same with round pin axle external diameter, and the blind plate is connected in round pin axle one end through the coaxial fixed connection of a plurality of screws, and the blind plate is kept away from round pin axle one end and is equipped with the arc chamfer.
The two ends of each bushing are respectively provided with a groove and a boss, and when two adjacent bushings are arranged together, one boss of each bushing is inserted into the groove of the other bushing.
The technical effects of the utility model are that: the mode of knocking the dismounting pin shaft is changed into a mode of knocking the hydraulic stretcher to dismount the pin shaft, the pin shaft of the travelling wheel of the bridge crane can be accurately and effectively extracted or loaded, the labor intensity is reduced, the safety is high, and the problems that the existing dismounting work wastes time and energy and has potential safety hazards are solved.
Drawings
The invention will be further explained with reference to the drawings:
FIG. 1 is a schematic sectional view of the hinge pin of the present invention when it is removed,
FIG. 2 is a schematic sectional view of the pin shaft of the present invention,
fig. 3 is a schematic diagram of the local enlarged structure of the present invention.
In the figure: the device comprises a nut 1, a hydraulic stretcher 2, a ring plate 3, a pull rod 4, a blind plate 5, an arc-shaped chamfer 51, a pin shaft 6, a walking wheel 7, a manual hydraulic pump 8, a bushing 9, a boss 91 and a groove 92.
Detailed Description
As shown in fig. 1 to 3, a bridge crane walking wheel round pin axle dismouting device, including pull rod 4, hydraulic stretching ware 2, the crown plate 3, manual hydraulic pump 8 and a plurality of bush 9, fixed connection is at the blind plate 5 of 4 one ends of pull rod through a plurality of screws and 7 round pin axle 6 fixed connection of walking wheel, hydraulic stretching ware 2, crown plate 3 and a plurality of bush 9 overcoat are in proper order outside pull rod 4, pull rod 4 exposes 2 one end of hydraulic stretching ware and 1 threaded connection of nut, manual hydraulic pump 8 is through hydraulic pressure pipe switch-on hydraulic stretching ware 2.
When the pin shaft 6 needs to be disassembled, as shown in fig. 1, hydraulic oil is pumped into the hydraulic stretcher 2 by using the manual hydraulic pump 8 to drive the stretcher to extend, after the pin shaft 6 is pulled out for a certain distance, the hydraulic stretcher 2 reaches a stretching limit position, then the nut 1 is loosened, the hydraulic stretcher 2 is taken down from the pull rod 4 and unloaded, then a bush 9 is added outside the pull rod 4, then the hydraulic stretcher 2 is installed again to pull the pin shaft 6, and the bush 9 is repeatedly pulled and added, so that the pin shaft 6 can be pulled out from the travelling wheel 7, and the disassembling work of the pin shaft 6 is completed.
When the pin shaft 6 needs to be installed, as shown in fig. 2, the pull rod 4 and the blind plate 5 penetrate through the pin hole, then the blind plate 5 is connected with the pin shaft 6, the bushing 9, the ring plate 3 and the hydraulic stretcher 2 are installed, and then the pin shaft 6 is pulled into the pin hole through the hydraulic stretcher 2, if the method for detaching the pin shaft 6 is the same, the bushing 9 is pulled and added repeatedly until the pin shaft 6 is pulled to a specified position.
The outer diameter of the blind plate 5 is the same as that of the pin shaft 6, the blind plate 5 is coaxially and fixedly connected to one end of the pin shaft 6 through a plurality of screws, and an arc-shaped chamfer 51 is arranged at one end, far away from the pin shaft 6, of the blind plate 5.
As shown in fig. 2, before the pin shaft 6 is installed, the blind plate 5 can be connected with the pin shaft 6, then the coaxiality of the blind plate 5 and the pin shaft 6 is checked through the hundredth table, then the pin shaft 6 is pulled into the pin hole, and because the arc-shaped chamfer 51 is arranged at one end of the pin shaft 6, the pin shaft 6 can be guided through the blind plate 5, and the problem of difficult penetration caused by the dislocation of two adjacent pin holes of the walking wheel 7 is solved.
The two ends of the bush 9 are respectively provided with a groove 92 and a boss 91, and when two adjacent bushes 9 are arranged together, the boss 91 of one bush 9 is inserted into the groove 92 of the other bush 9. The structure arrangement of the bushings 9 ensures that two adjacent bushings 9 can be coaxial when assembled together, and plays a role in limiting, so that the bushings 9 can be uniformly stressed, and the bushings 9 are prevented from being stressed and deflected.
