Abstract
The utility model relates to a device for disassembling an S-shaped pipe valve conveniently. The device adopts the structure that the large end (8) of an S-shaped pipe is sleeved with a large end abrasion-resistant sheath (7); a groove is formed in one end of the large end abrasion-resistant sheath (7); a lug boss (10) and a hoop (11) are respectively mounted on the S-shaped pipe (5); a groove and a bulge are formed in the hoop; the lug boss (10) is embedded in the groove in the hoop (11); the bulge of the hoop (11) is embedded into the groove in the large end abrasion-resistant sheath (7). The device is used for construction machinery such as vehicle-mounted concrete pumps, concrete trailer pumps and concrete pump trucks. All that is needed is to connect the S-shaped pipe with the large end abrasion-resistant sheath into a whole. When force is applied to the S-shaped pipe and the large end abrasion-resistant sheath, the large end abrasion-resistant sheath moves out of a discharge opening and drives the S-shaped pipe to move out of the discharge opening, that is, the purpose of disassembling the S-shaped pipe is achieved. The device has the advantages that the S-shaped pipe can be disassembled simply only with simple disassembling tools; the structure is simple; time and labor are saved; the operating efficiency is high.

Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of device of being convenient to dismantle S pipe valve, is mainly used in concrete mixer, concrete pump, Vehicle loaded pump etc.
Background technology
In concrete construction, require to carry fast, timely cast concrete.And concrete mixer integrates vertically, horizontal feed concrete, in concrete casting process, play the important effect of core.And S pipe valve is responsible for concrete distribution, it is the core component in pumping system.But due to the wearing and tearing of consumable accessory, usually need to dismantle S pipe valve.Fig. 1 is conventional S pipe valve structure figure.The small end of 1-S pipe, 2-eye slab, 3-cut ring, 4-small end wear-resistant sleeve, 5-S pipe, 6-bucket wall, the large end wear-resistant sleeve of 7-, the large end of 8-S pipe, 9-liftout bolt.The small end of S pipe is connected with oscillating oil cylinder by spline housing.Oscillating oil cylinder swings and drives S pipe, cut ring to swing, and completes concrete distribution.Eye slab 2 and cut ring 3 in swing process, S pipe 5 and small end wear-resistant sleeve 4, hold greatly the friction repeatedly at wear-resistant sleeve 7 places, all can cause wearing and tearing in various degree, therefore needs regular replacing.In Renewal process, all need S pipe to move suitable distance towards the direction of the large end of S pipe.Move towards large end at S pipe or unloading process in, due to the small end of S pipe and the large end of S pipe and small end wear-resistant sleeve, to hold wear-resistant sleeve be greatly all interference fit.Therefore need to knock S pipe small end with jack or sledgehammer, this dismounting is wasted time and energy, and jack cannot use because often can not find fulcrum.
Summary of the invention
The utility model object is to provide a kind of device of being convenient to dismantle S pipe valve.This device connects as one S pipe and large end wear-resistant sleeve.In the time of dismounting S pipe, only need tighten liftout bolt, liftout bolt ejects large end wear-resistant sleeve under the reaction force of bucket wall.Thereby drive S pipe to shift out small end wear-resistant sleeve, reach the object of dismounting S pipe valve.This apparatus structure is simple, and processing ease has reduced labor strength, has improved widely operating efficiency.
The technical solution of the utility model is:
Be convenient to dismantle the device of S pipe valve, comprise boss 10, clip 11, hold wear-resistant sleeve 7 greatly, hold greatly wear-resistant sleeve 7 to be enclosed within on the large end 8 of S pipe, it is characterized in that: described large end wear-resistant sleeve 7 one end are provided with groove, boss 10 and clip 11 are arranged on respectively on S pipe 5; Described clip is provided with groove and projection, and boss 10 embeds in the groove of clip 11, and the projection of clip 11 embeds in the groove of large end wear-resistant sleeve 7.
Be convenient to dismantle the device of S pipe valve, comprise boss 10, clip 11, hold wear-resistant sleeve 7 greatly, large end wear-resistant sleeve 7 is enclosed within on the large end 8 of S pipe, it is characterized in that: described large end wear-resistant sleeve 7 one end are provided with screwed hole, boss 10 and clip 11 are arranged on respectively on S pipe 5, the hole that described clip is provided with groove and matches with large end wear-resistant sleeve screwed hole; And boss 10 embeds in the groove of clip 11, clip 11 is connected by bolt and large end wear-resistant sleeve 7 screwed holes.
Described clip comprise first clip 12, second clip 15, bearing pin 13, slip-knot bolt 14 with nut, one end of first clip 12, second clip 15 is hinged and connected by bearing pin 13, and the other end of first clip 12, second clip 15 is controlled and closed by the slip-knot bolt 14 with nut.
The structural principle of this device is:
When the groove of clip 11 matches with the boss 10 being arranged on S pipe 5, when the projection of clip 11 matches with the groove of large end wear-resistant sleeve 7, tighten the nut on slip-knot bolt 14, make S pipe 5 and large end wear-resistant sleeve 7 be connected to an entirety by clip 11.In the time tightening liftout bolt 9, the screwing force of liftout bolt 9 acts on bucket wall 6 uniformly, tightens liftout bolt 9 under the reaction force of bucket wall 6 simultaneously, drives large end wear-resistant sleeve 7 to move toward discharging opening direction.Be an entirety because clip 11 makes S pipe 5 and large end wear-resistant sleeve 7, thereby hold greatly the mobile S of the drive pipe 5 of wear-resistant sleeve to move toward discharging opening direction, reach the object of dismounting S pipe.
The power that only need apply in large end one end of S pipe in this device can reach the object of dismounting S pipe.And traditional dismounting need all apply very large power at the large end of S pipe, small end, and the bad application of force.In contrast to this, this apparatus structure is simple, convenient and swift, time saving and energy saving, has improved operating efficiency.
