The utility model discloses a construction elevator standard festival rack coupling assembling has solved current construction elevator standard festival and rack junction and has taken place fatigue fracture and the crooked technical problem of stress easily.
Description
Technical field
The utility model relates to a kind of building hoist standard knot tooth bar coupling assembling.
Background technology
Tooth bar on building construction hoist standard knot is very important parts in complete machine engine installation.Existing tooth bar is generally by cushion block and standard knot weld together, output pinion on the actuating device of elevator engages with this tooth bar, when the pinion is rotated, all the time remain static because tooth bar is connected with standard knot, the counter-force that tooth bar produces promotes driving device and moves towards the direction of counter-force, and the cage contacted with driving device is driven by driving device and runs.When in raised, miniature gears acts on shearing force downward on tooth bar and bears primarily of cushion block weld, and elevator is frequently elevated, tired by making the solder joint place of cushion block produce, and then easily ruptures, and elevator interruption of service occurs.Although there is at present the technology adopting bolt to come connection construction elevator standard knot and tooth bar, this technology cannot solve the problem that bolt looseness and bolt stress bend.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of building hoist standard knot tooth bar coupling assembling, and this building hoist standard knot tooth bar coupling assembling can solve the fracture by fatigue that the connection mode between existing building hoist standard knot and tooth bar exists, the technical matters that stress is bending well.
The utility model is solved the problems of the technologies described above by following technological means:
A kind of building hoist standard knot tooth bar coupling assembling of the present utility model, comprise jam nut B bolt, jam nut A, packing ring and outer circumference surface being provided with flange, described jam nut A and jam nut B coordinates with bolt thread; Described gasket sleeve is located on jam nut B, for clamping elevator standard knot between a side end face of described packing ring and a side end face of jam nut B flange, for locking rack between the opposite side end face of packing ring and the nuts end face of bolt.
Further, the arranged outside of described packing ring has one along the stay bearing plate that packing ring radial direction extends, and described packing ring one side end face is mutually concordant with stay bearing plate side plate face.
Further, the side plate face of described stay bearing plate is provided with projection, this lateral plates is mutually concordant with a side end face of described packing ring.
The beneficial effects of the utility model: building hoist standard knot tooth bar coupling assembling of the present utility model, comprise jam nut B bolt, nut, packing ring and outer circumference surface being provided with flange, described gasket sleeve is located on jam nut B, described bolt can pass and coordinate with the nut thread of jam nut B opposite side from described jam nut B, and between described bolt with jam nut B, circumference is fixedly connected with; Described packing ring is fixedly connected with jam nut B circumference; The arranged outside of described packing ring has one along the stay bearing plate that packing ring radial direction extends, and described packing ring one side end face is mutually concordant with stay bearing plate side plate face.Building hoist standard knot tooth bar coupling assembling of the present utility model, solves existing building hoist standard knot and tooth bar junction and fracture by fatigue and the bending technical matters of stress easily occurs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of building hoist standard knot tooth bar coupling assembling in the utility model embodiment 1;
Fig. 2 is the structural representation of building hoist standard knot tooth bar coupling assembling in the utility model embodiment 2.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail:
Embodiment 1 building hoist standard knot tooth bar coupling assembling
As shown in Figure 1: the building hoist standard knot tooth bar coupling assembling in the present embodiment, comprises jam nut B4 bolt 1, jam nut A2, packing ring 3 and outer circumference surface being provided with flange 5, described jam nut A2 and jam nut B4 and bolt 1 screw thread fit, described packing ring 3 is set on jam nut B4, for clamping the steel plate 8 on elevator standard knot between one side end face of described packing ring 3 and a side end face of jam nut B flange 5, particularly, described steel plate 8 is provided with the through hole corresponding to the external diameter size of jam nut B, during connection, first jam nut B4 is inserted in above-mentioned through hole, flange 5 on jam nut B4 props up the edge of through hole side, described packing ring 3 be set in jam nut B4 props up through hole opposite side edge to step up elevator standard knot steel plate 8, for locking rack between the opposite side end face of described packing ring 3 and the nuts end face of bolt 1.Building hoist standard knot tooth bar coupling assembling of the present utility model, solves existing building hoist standard knot and tooth bar junction and fracture by fatigue and the bending technical matters of stress easily occurs.
Embodiment 2 building hoist standard knot tooth bar coupling assembling
As shown in Figure 2: the building hoist standard knot tooth bar coupling assembling in the present embodiment, comprise bolt 1, jam nut A2, packing ring 3 and one end are provided with the jam nut B4 of flange 5, described packing ring 3 is set on jam nut B4, described bolt 1 can from described jam nut B4 through and with the jam nut A2 screw thread fit of jam nut B4 opposite side, between described bolt with jam nut B4, circumference is fixedly connected with, particularly, the screw rod of described bolt 1 its arrange in prismatic near bolt cap side, arrange externally threaded cylindrical in being processed with away from bolt cap side, inside described jam nut B4, the shape of bore is corresponding with size to the shape of cross section of the prismatic screw rod of bolt 1 with size, described packing ring 2 is fixedly connected with jam nut B4 circumference, the arranged outside of described packing ring 2 has one along the upper stay bearing plate 6 extended of packing ring 2 radial direction, and described packing ring 2 one side end face is mutually concordant with stay bearing plate 6 side plate face.By arranging stay bearing plate, the torsion of bolt can be reduced, prevent bolt stress from bending, be fixedly connected with in circumference additionally by by arrange between described bolt with jam nut B4, between packing ring 2 with jam nut B4, bolt be there will not be and slide and rotate, avoid the predetermincd tension between bolts and nuts to diminish.
As the further improvement of technique scheme, the side plate face of described stay bearing plate 6 is provided with protruding 7, this lateral plates is mutually concordant with a side end face of described packing ring 2; Steel plate 8 on described standard knot tooth bar is provided with the diameter through hole corresponding to jam nut B4 external diameter size above, and on the plate face of described plate body 8, the position be positioned at below described through hole is provided with a groove 9 of fitting with described protruding 7 phase interworkings.By coordinating of stay bearing plate 6 projection 7 and through hole, stay bearing plate can not be rotated, and then the problem preventing the predetermincd tension between the bolts and nuts that cause because bolt rotates from diminishing occur.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
