Description
Technical field
The utility model relates to the concrete mixer that construction industry is used, particularly a kind of quick outer reassembling type shaft sealer that is used for the concrete mixer of single horizontal axis and dual horizontal axle.
Background technique
The concrete mixer that is used for construction industry for a long time after use a period of time, spillage can occur at the main shaft two ends, if untimely replacing shaft sealer, will cause bearing, bearing support, main shaft to damage, can bring adverse consequences, also can influence concrete production equipment operation.If keep in repair, then must change old-fashioned labyrinth-type excluder, must pull down hinge wheel, bearing support earlier, could change seal arrangement then.The dismounting maintenance very bothers like this, and maintenance difficulty is big again, and every replacing once needs 24 hours, needs a couple of days sometimes, and its replacing speed is slow, and maintenance cost is higher.
Summary of the invention
Task of the present utility model provides a kind of improved outer reassembling type shaft sealer fast, and it has solved the problem that existing shaft sealer dismounting maintenance bothers, replacing speed is slow, maintenance cost is high.
The technical solution of the utility model is as follows:
A kind of outer reassembling type shaft sealer fast, it comprises bearing support and the bearing that is positioned at the concrete mixer both sides, be placed in main shaft wherein, shaft sealer, and be placed in butter pipe on the shaft sealer, described shaft sealer comprises that one is packed in the stuffing box gland that is the outer inclined-plane of two semicircular tools on the main shaft, be clamped in the diaphragm seal on the outer inclined-plane of stuffing box gland more than two, one is pressed in the diaphragm seal pressing plate on the diaphragm seal of outer end, two the semicircular diaphragm seal pressure rings that are that have the butter oil duct more than one between two above diaphragm seals, one is fixedly mounted on two the semicircular diaphragm seal liner plates that are on the inner shafts bearing by hexagon socket head cap screw, and one is placed through between diaphragm seal pressing plate and above diaphragm seal pressure ring and the inner shafts bearing and makes the sealing plate fixing bolt that they are fixed together.
Adopt outer reassembling type shaft sealer fast of the present utility model, can prolong the working life of concrete mixer equipment, accelerate maintenance speed, reduce maintenance cost, satisfy users' usage requirement.
Description of drawings
Fig. 1 is a kind of structural representation that the quick outer reassembling type shaft sealer of two diaphragm seals is housed of the present utility model.
Fig. 2 is a kind of structural representation that the quick outer reassembling type shaft sealer of three diaphragm seals is housed of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, fast outer reassembling type shaft sealer of the present utility model comprises bearing support 1,2 and the bearing 3 that is positioned at the concrete mixer both sides, is placed in main shaft 5 wherein, shaft sealer, and be placed in butter pipe 6 on the shaft sealer.The utility model is installed in main shaft 5 two ends, and inner shafts bearing 2 is connected on the cylindrical shell 4 of concrete mixer by fixing bolt 12.
Shaft sealer is equipped with stuffing box gland 7, diaphragm seal 8, diaphragm seal pressing plate 9, diaphragm seal pressure ring 10, diaphragm seal liner plate 11 and sealing plate fixing bolt 13.Stuffing box gland 7 is two semicircles, has outer inclined-plane, is installed on the main shaft 5.Diaphragm seal 8 has two (as shown in Figure 1) or three (as shown in Figure 2).Diaphragm seal 8 is the fracture shape, is clamped in respectively on the outer inclined-plane of stuffing box gland 7.Diaphragm seal 8 is located by locating stud at incision position, with glue fracture is glued together again, is convenient to dismounting.Diaphragm seal pressing plate 9 is full circle shape, also can be two semicircles, is pressed on the outside of outer end diaphragm seal 8.Diaphragm seal pressure ring 10 has butter oil duct 61, can be installed in (see figure 1) between diaphragm seal 8 and the bearing support 2, also can be installed in respectively between two diaphragm seals 8 and diaphragm seal 8 and bearing support 2 between (see figure 2).Install one and be two semicircular diaphragm seal liner plates 11 on inner shafts bearing 2, sealing sheet liner plate 11 is fixedly mounted on the inner shafts bearing 2 by hexagon socket head cap screw 111.One sealing plate fixing bolt 13 is set between diaphragm seal pressing plate 9 and above diaphragm seal pressure ring 10 and the inner shafts bearing 2 and they is fixed together.
What be positioned at stuffing box gland 7 the inners on main shaft 5 is equipped with pressure-reducing ring 14 with diaphragm seal liner plate 11 relative position places.
Bearing thrust ring 15 is fixed tightly on the main shaft 5 by the top screw, to prevent main shaft 5 horizontal looseness.
Stuffing box gland 7 and diaphragm seal liner plate 11 can be made into two semicircles, they are made by high molecular abrasion-proof material or wear-resistant metal material, 8 of diaphragm seals are made by wear-resisting, oil resistant rubber or polyurethane, so both can improve the working life of part, are convenient to the dismounting maintenance again.
When concrete mixer is installed the utility model, two semicircle stuffing box gland 7 usefulness retaining screws are connected on the main shaft 5, and closely cooperate with main shaft 5, diaphragm seal pressing plate 9 and an above diaphragm seal pressure ring 10 are installed on the bearing support 2 tightly by being distributed on four sealing plate fixing bolts 13 on the bearing support 2.Wherein diaphragm seal pressing plate 9 is two semicircles, also can be made into whole circle, and diaphragm seal pressing plate 9 is pressed on diaphragm seal 8 on the stuffing box gland 7.Stuffing box gland 7 is two semicircles, forms full circle shape by two fastening screws, is fixedly mounted on the main shaft 5 with the top screw.
Stuffing box gland 7 is according to the direction of arrow, can pass in and out to be installed in easily on the main shaft 5.Again two above diaphragm seals 8 are clamped on the outer inclined-plane of stuffing box gland 7, form zigzag tight contact.Butter enters diaphragm seal pressure ring 10 oil ducts 61 from butter pipe 6 under oil pump work, enter the oil seal chamber again, and forms certain oil pressure, prevents that in the mode of oily water proof pulp-water from from inside outwards flowing.
When changing diaphragm seal 8, according to the direction of arrow, outside stirrer, take sealing plate fixing bolt 13 apart, respectively diaphragm seal pressing plate 9 and diaphragm seal pressure ring 10 are taken out, just can change diaphragm seal 8.This shows that when main shaft 5 two ends spillage occurs and when needing maintenance and changing stuffing box gland 7 and diaphragm seal 8, the maintenance man need not arrive dismounting inside the stirrer, also need not pull down hinge wheel and bearing support, change according to above method, obviously improved maintenance speed, reduced labor intensity.
