Abstract
The utility model discloses a kind of Novel pin remover, relate to extracting tool technical field, comprise crossbeam and two screw rods, two screw rods be symmetricly set on crossbeam two ends and with crossbeam threaded engagement, be provided with the screwed hole with bearing pin top to be replaced threaded engagement in the middle part of described crossbeam.Utilize screwed hole in the middle part of crossbeam to coordinate with bearing pin threaded upper ends to be replaced, then withstand on pusher shell by the screw rod lower end at crossbeam two ends, drive crossbeam to rise while rotating screw bolt, and then drive bearing pin to rise, bearing pin is extracted the most at last.The utility model has simple, the easy to operate advantage of structure, simple for production, economical and practical, stable performance, utilize the utility model can save manpower and materials in maintenance process, greatly reduce equipment influence time, improve maintenance efficiency, reduce the labour intensity of workman, also improve utilization rate of equipment and installations.
Description
Technical field
The utility model relates to extracting tool technical field.
Background technology
Pusher top on sky vehicle brake is provided with bearing pin, and because of bearing pin and pusher interference fit and exposed parts is provided with external screw thread, corrosion or wearing and tearing easily appear in bearing pin exposed parts, and along with the prolongation of running time, bearing pin fault rate also increases thereupon.When there is heavy wear in bearing pin, easily cause rocking of brake, equipment cannot normally be run, especially when there is fracture in the wearing and tearing of bearing pin rust corrosion, maintenance personal is difficult to the bearing pin of fracture to take out change, and spended time is longer, adds the workload of maintenance personal, material consumption is also increased thereupon, and equipment influence time extends.In order to meet need of production, reduce maintenance time, improve the maintenance efficiency of bearing pin, we have devised Novel pin remover through calculating.
Utility model content
Technical problem to be solved in the utility model is to provide simple, the easy to operate Novel pin remover of a kind of structure, reduces the labour intensity of workman, improves maintenance efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of Novel pin remover, comprises crossbeam and two screw rods, two screw rods be symmetricly set on crossbeam two ends and with crossbeam threaded engagement, be provided with the screwed hole with bearing pin top to be replaced threaded engagement in the middle part of described crossbeam.
Preferably, be provided with sleeve in the middle part of described crossbeam in screwed hole, described sleeve lower end is provided with blind hole, is provided with the internal thread with bearing pin top to be replaced threaded engagement in described blind hole.
Preferably, described sleeve and screw tip are equipped with nut, the external screw thread that described sleeve peripheral hardware coordinates with screwed hole in the middle part of crossbeam.
Preferably, described cartridges sides is provided with top wire hole, described top wire hole and blind hole through.
The beneficial effect adopting technique scheme to produce is: utilize the sleeve be arranged on crossbeam to coordinate with bearing pin threaded upper ends to be replaced, again the screw rod lower end at crossbeam two ends is withstood on pusher shell, crossbeam is driven to rise while rotating screw bolt, and then driving bearing pin to rise, bearing pin is extracted the most at last; For the bearing pin that external screw thread corrosion is serious, recycle jackscrew and held out against fixing after coordinating with sleeve, then repeat above step and bearing pin can be extracted.The utility model has simple, the easy to operate advantage of structure, simple for production, economical and practical, stable performance, utilize the utility model can save manpower and materials in maintenance process, greatly reduce equipment influence time, improve maintenance efficiency, reduce the labour intensity of workman, also improve utilization rate of equipment and installations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of Fig. 1 middle sleeve;
In figure: 1-crossbeam, 2-screw rod, 3-bearing pin, 4-sleeve, 5-nut, 6-top wire hole, 7-blind hole, 8-pusher shell.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of Novel pin remover as shown in Figure 1, 2, comprise crossbeam 1 and two screw rods, 2, two screw rods 2 be symmetricly set on crossbeam 1 two ends and with crossbeam 1 threaded engagement, be provided with the screwed hole with bearing pin 3 top to be replaced threaded engagement in the middle part of described crossbeam 1.
As a kind of preferred structure, in the middle part of crossbeam 1, be provided with sleeve 4 in screwed hole, described sleeve 4 lower end is provided with blind hole 7, is provided with the internal thread with bearing pin 3 top to be replaced threaded engagement in described blind hole 7.
Conveniently installing sleeve 4 and rotating screw bolt 2, be equipped with nut 5 at sleeve 4 and screw tip, the external screw thread that described sleeve 4 peripheral hardware coordinates with screwed hole in the middle part of crossbeam 1.Sleeve 4 after a long time use blind hole 7 internal thread can lose efficacy, the more convenient replacing of sleeve 4 of flexible connection.
For the bearing pin 3 that external screw thread corrosion is serious, active force between itself and sleeve 4 is very little, top wire hole 6 is provided with in sleeve 4 side, by through to top wire hole 6 and blind hole 7, sleeve 4 is enclosed within bearing pin 3, recycling jackscrew coordinates with top wire hole 6 and holds out against fixing by bearing pin 3, sleeve 4 and bearing pin 3 slippage when avoiding rotating screw bolt 2.
During concrete use, utilize the sleeve 4 be arranged on crossbeam 1 to coordinate with bearing pin 3 threaded upper ends to be replaced, then screw rod 2 lower end at crossbeam 1 two ends is withstood on pusher shell 8, while rotating screw bolt 2, drive crossbeam 1 to rise, and then driving bearing pin 3 to rise, bearing pin 3 is extracted the most at last; For the bearing pin that external screw thread corrosion is serious, coordinate with sleeve 4 rear recycling jackscrew to be held out against fixing, then repeat above step and bearing pin 3 can be extracted.
In sum, the utility model has simple, the easy to operate advantage of structure, simple for production, economical and practical, stable performance, utilize the utility model can save manpower and materials in maintenance process, greatly reduce equipment influence time, improve maintenance efficiency, reduce the labour intensity of workman, also improve utilization rate of equipment and installations.
