Description
Technical field
The utility model relates to extracting tool, specifically relates to a kind of frock that is applicable to dismantle the row's of hanging hanging axis in gantry crane.
Background technology
In use, due to the lifting difference of condition and the needs of maintenance, often can change the row's of hanging dismounting into townhouse maybe will the row's of hanging detachable maintaining for gantry crane.When axle is torn open to by the row of hanging, common way is by the hanging axis handle of the row's of hanging hanging axis self, carries out tractive, rotation, even beats by some interim complementary tools, and this method for dismounting is relatively required great effort, and efficiency is extremely low, and has potential safety hazard.
Utility model content
The utility model object is, provide a kind of simple in structure, easy to operate, tear open shaft efficiency high tear axle frock open.
The utility model is achieved through the following technical solutions this object:
One is torn axle frock open, comprises pull bar, pull bar mount pad, shaft connector and rotating spanner; On described pull bar mount pad, offer tapped through hole, described pull bar is provided with the screw thread coordinating with the tapped through hole of pull bar mount pad; When described shaft connector is fixed on axle one end, pull bar one end inlay card is in the space that axle and shaft connector surround; Described rotating spanner is installed on the other end of pull bar, and can drive the axis rotation of pull bar with pull bar.
The periphery of the one end preferably, being connected with shaft connector in described pull bar offers annular slot; Described shaft connector comprises snap ring, and the connecting ring rigidly fixing with snap ring, and described snap ring is rigidly fixed and formed by two halves snap ring, and interior all inlay cards of snap ring are in annular slot; When described shaft connector is fixed on axle one end, connecting ring and axle rigidly fix.
Preferably, described rotating spanner is provided with non-circular installing hole, and described pull bar is provided with the boss coordinating with this installing hole.More excellent, described installing hole is square hole.
Preferably, described in, tearing axle frock open also comprises and the rigidly connected fixture of pull bar mount pad; Described while tearing axle frock dismounting axle open, fixture is also rigidly connected with axle bed.
Compared with prior art, it is as follows that the utility model is torn the beneficial effect of axle frock open:
1) simple in structure, safe and reliable, easy to operate.
2) described in, tear axle frock open and be installed on loop wheel machine and hung row when upper, neither affect loop wheel machine and hang the technical requirement in row's use procedure, can improve again loop wheel machine and hang the efficiency that row tears axle open.

Detailed description of the invention
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Figure 1 shows that the utility model tears one of them embodiment of axle frock open.
Referring to Fig. 1, described in tear axle frock open and comprise pull bar 2, pull bar mount pad 3, shaft connector 4 and rotating spanner 5.On described pull bar mount pad 3, offer tapped through hole, described pull bar 2 is provided with the screw thread coordinating with the tapped through hole of pull bar mount pad 3.Referring to Fig. 3, when described shaft connector 4 is fixed on axle 1 one end, in the space that pull bar 2 one end inlay cards surround in axle 1 and shaft connector 4.Described rotating spanner 5 is installed on the other end of pull bar 2, and can drive the axis rotation of pull bar 2 with pull bar 2.
Concrete, described pull bar mount pad 3 is nut.Referring to Fig. 3, the described axle frock of tearing open is installed on loop wheel machine and hung row when upper, nut-welding is on baffle plate 6, described shaft connector 4 is welded in one end of axle 1, while rotating described rotating spanner 5, pull bar 2 moves right along its axis, and in the process that pull bar 2 moves right, also pulls axle 1 to move, thereby can realize, axle 1 is taken apart from the row of hanging.
Referring to Fig. 1, the periphery of the one end (being left end) being connected with shaft connector 4 in pull bar 2 offers annular slot 7.Described shaft connector 4 comprises snap ring 8, and the connecting ring 9 being welded and fixed with snap ring 8.Described snap ring 8 is welded and fixed and is formed by two halves snap ring, and interior all inlay cards of snap ring 8 are in annular slot 7.Referring to Fig. 3, when described shaft connector 4 is fixed on axle 1 one end, connecting ring 9 is welded and fixed with axle 1.
Referring to Fig. 3, described rotating spanner 5 is provided with square hole 10.Referring to Fig. 1, described pull bar 2 is provided with the boss 11 coordinating with this installing hole, and certainly, the cross section of this boss 11 is also square, thereby when rotating spanner 5 rotates, can drive the axis rotation of pull bar 2 with pull bar 2.
Referring to Fig. 1, described in tear axle frock open and also comprise the fixture 12 being fixedly linked with pull bar mount pad 3.In the present embodiment, described fixture 12 is for strengthening band iron, and one end of described fixture 12 and pull bar mount pad 3 are welded and fixed.Referring to Fig. 3, described in tear axle frock open and be installed on loop wheel machine and hung row when upper, the other end of fixture 12 is fixed with the row's of hanging Main Girder Welding.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
