Abstract
The utility model provides a traction beam conical sleeve push dismounting tooling, which consists of a jack, a regulation circular disc, connecting rods and grippers, wherein the regulation circular disc is fixed on a screw stud of the jack, three connecting rods are uniformly distributed and hinged on the periphery of the regulation circular disc at 120 degrees, the grippers are hinged on the middle part of each connecting rod for forming a 120-degree three-point adjustable support seat, the jack top of the jack is positioned in the center position of the regulation circular disc and can extend and contract in the axial direction, the grippers are driven to move through the stroke of the jack, and a traction beam conical sleeve has the displacement. Because contact surfaces of pulley weights and the conical sleeve are in uniform distribution, the damage to the conical sleeve can not be caused, and the problem that the conical sleeve can not be dismounted by the existing dismounting tool sometimes is solved. The utility model has the advantages of practicability, simple structure and convenient operation.
Description
Technical field:
The utility model provides a kind of draw beam taper sheath to shirk frock, is used for the dismounting of CRH5 EMUs draw beam, belongs to mechanical tooling device technical field.
Background technology:
The dismounting of existing C RH5 type EMUs draw beam, mostly adopt hydraulic jack to dismantle, adopt the special dismounting bolt, it is screwed in the screwed hole of draw beam taper sheath below, slowly bolt is being pulled down by hydraulic jack, thereby will the draw beam taper sheath pulled down together by bolt.But because the draw beam taper sheath is connected too fasteningly with centrepin sometimes, the screw thread with demounting bolt has damaged owing to pulling force is excessive exactly, also the draw beam taper sheath can't be pulled down.
Summary of the invention
The utility model provides a kind of draw beam taper sheath to shirk frock, has solved the problem that existing extracting tool can't be dismantled the draw beam taper sheath sometimes.
The technical solution of the utility model is as follows:
Constitute by hydraulic jack, adjusting disk, connecting rod and gripper, regulating disk is fixed on the double-screw bolt of jack, 3 connecting rods are even distribution of 120 degree and are hinged on the periphery of regulating disk, the middle part of every connecting rod is hinged with gripper and constitutes 3 of 120 degree and can adjust bearing, can stretch vertically in the top centre of regulating disk that is positioned at of jack.
The good effect of utility model is: the bearing the adjusted mechanism that regulates disk, connecting rod, gripper formation is installed on jack, gripper and taper sheath contact-making surface are evenly distributed, utilize the lifting of jack to finish the dismounting of draw beam taper sheath, realize the nondestructive demounting of draw beam taper sheath.Having solved existing extracting tool sometimes can't be with the problem of its dismounting.The utility model practicality, simple in structure, easy to operate.
Description of drawings
Fig. 1 is the utility model structure principle chart.
1, connecting rod; 2, chest expander; 3, regulate disk; 4, jack; It is 5, top.
The specific embodiment
According to shown in Figure 1, the utility model is made of jack 4, adjusting disk 3, connecting rod 1 and gripper 2, regulating disk 3 is fixed on the double-screw bolt of jack 4,3 connecting rods 1 are even distribution of 120 degree and are hinged on the periphery of regulating disk 3, the middle part of every connecting rod 1 is hinged with gripper 2 and constitutes 120 ° 3 and can adjust bearing, top 5 of jack 4 is positioned at the centre of regulating disk 3, can stretch vertically.
When dismounting draw beam taper sheath, regulate the adjusting disk 3 on jack 4 double-screw bolts earlier, will reconcile disk 3 and transfer to the appropriate location with gripper 2 parts such as grade.Again three upper ends of grippers 2 that are mutually 120 degree are fixed on the top of taper sheath, top 5 of hydraulic jack 4 withstands on (taper sheath is enclosed within on the draw beam centrepin) on the draw beam centrepin by bolt and pad, along with top 5 stroke of jack 4 upwards constantly increases, jack 4 drive conciliation disks 3, connecting rod 1, gripper 2 move downward together, thereby the draw beam taper sheath are disassembled.
