Description
Technical field
The utility model relates to the realm of building construction, especially a kind of urceolus of easy-to-mount shield screw conveyer.
Background technology
Domestic city subway construction fast development at present, balancing earth-pressure shielding machine is in great demand.In shield-tunneling construction process, when shield machine is during in the construction of sandy gravel bottom or rock stratum, conveying worm is as the important component part of shield machine, its Main Function is for deslagging and step-down, mainly the sand of carrying to be got off by knife cutting, cobble, earth or rock block, sandy gravel or rock fragment are very serious to the wearing and tearing of helical feed machine drum body, while just having entered conveying worm due to sandy gravel or rock block etc., entirety is irregular status, now very serious to the cylindrical shell wearing and tearing of conveying worm, work long hours in this kind of stratum, conveying worm cylinder inner surface will be ground, and cause conveying worm transfer efficiency to decline, when serious, just need to change cylindrical shell.Existing conveying worm has one-part form conveyer, and in the time that material conveying process is longer, this conveying worm often can not meet the requirement of convey materials.Another is the split type conveyer of multistage, can meet length apart from mass transport, and because slag charge is more serious at the beginning of conveyer blockage ratio, urceolus dismounting inconvenience, has affected the discharge of dregs to a great extent.
Through retrieval, application number is that 200910157795.1 patent discloses a kind of Novel screw conveyor front barrel, and in manual, disclosed outer tube structure is segmented, is divided into three sections, be respectively conveyor front barrel, middle cylinder body and further part, three connects by adpting flange.The technical problem that this structure solves is to be convenient to change, but in the time occurring stopping up in cylindrical shell, the dregs that inconvenience cleaning is inner.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of separable conveying worm urceolus, and this urceolus is convenient to dismounting, can reduce well the obstruction of the slag charge in conveyer, improves conveyer delivery efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of separable conveying worm urceolus, it is characterized in that comprising front urceolus, middle urceolus and rear urceolus, described front urceolus and middle urceolus are semi-open type, separable urceolus, and be divided into first cylinder and second cylinder, first and second cooperation forms complete cylinder, rear urceolus is straight tube, front urceolus, in middle urceolus and rear urceolus, external diameter is identical, between described front urceolus and middle urceolus, and all connect by flange between middle urceolus and rear urceolus, between described flange, be provided with sealing ring.
Said structure is described further, and first cylinder of described front urceolus and middle urceolus is connected by bolt group with second both sides, and is furnished with sealing mat.
Said structure is described further, and first of described front urceolus and middle urceolus and second a side are that bearing pin is connected, and opposite side is that bolt connects, and bilateral is all furnished with sealing mat.
Said structure is described further, and the length ratio of described front urceolus, middle urceolus and rear urceolus is 1:2 ~ 3:5 ~ 7.
Said structure is described further, and the length ratio of described front urceolus, middle urceolus and rear urceolus is 1:3:7.
The beneficial effect that adopts technique scheme to produce is: in the utility model, conveying worm urceolus is divided into three sections, and every two intersegmental employing flanges connect.Front two sections of cylindrical shells are upper and lower separable semicircular cylinder, link together by bolt group, final stage is straight tube, can effectively clear up like this slag charge obstruction that starts section, the more serious problem of beginning section putty that solves conveyer, has improved transfer efficiency largely; In addition, between each cylindrical shell, connect by flange, easy accessibility, is convenient to maintenance, increases gasket seal, can effectively play sealing function.

Fig. 2 is a kind of type of attachment of A-A section in Fig. 1;
Fig. 3 is the another kind of type of attachment of A-A section in Fig. 1;
Wherein, 1, front urceolus, 2, middle urceolus, 3, rear urceolus, 4, the first flange, 5, the second flange.
The specific embodiment
Known with reference to the accompanying drawings, the utility model is specifically related to a kind of separable conveying worm urceolus, for shield screw conveyer, and especially can easy-to-mount separable urceolus, can reduce well the obstruction of the slag charge in conveyer, improve conveyer delivery efficiency.
The utility model specifically comprises front urceolus 1, middle urceolus 2 and rear urceolus 3, front urceolus 1 and middle urceolus 2 are semi-open type, separable urceolus, and be divided into first cylinder and second cylinder, first and second cooperation forms complete cylinder, rear urceolus 3 is straight tube, the inside and outside footpath of front urceolus 1, middle urceolus 2 and rear urceolus 3 is identical, between front urceolus 1 and middle urceolus 2 and between middle urceolus 2 and rear urceolus 3, all connects by flange, is provided with sealing ring between flange.The utility model has been broken through the susceptible to plugging deficiency of conveying worm of tubular type in the past, has adopted the separable conveyer urceolus of segmented, has improved largely transfer efficiency.Between each cylindrical shell, connect by flange in addition, also can effectively play sealing function.
In addition, for convenience detach in order to guarantee conveyer urceolus, and the inner dregs of easy cleaning, can adopt following two schemes: first cylinder of (1) front urceolus 1 and middle urceolus 2 is connected by bolt group with second both sides, and is furnished with sealing mat; (2) first and second a side of front urceolus 1 and middle urceolus 2 is that bearing pin is connected, and opposite side is that bolt connects, and bilateral is all furnished with sealing mat.Two schemes easy accessibility, is convenient to maintenance, effectively reduces conveying worm slag charge blockage, has improved transfer efficiency.
The scheme that the utility model adopts is: in conveying worm urceolus, the length ratio of front urceolus 1, middle urceolus 2 and rear urceolus 3 is 1:2 ~ 3:5 ~ 7, preferably 1:3:7, be that urceolus total length is that first 1 meter of 11 meters of conveyers are made as front urceolus 1, middle urceolus 2 is 3 meters, remaining rear urceolus 3 is 7 meters, because the 1 place's putty of urceolus before the beginning section of conveyer is when more serious, takes front urceolus 1 apart and can clear up like this, alleviated well the blockage of carrying slag charge when conveying worm starts.Deng operation a period of time, urceolus 2 in can clearing up, rear urceolus 3 place's dregs putty probability are little, therefore select straight tube.Between every two sections of urceolus, adopt flange to connect.Front two sections of cylindrical shells are upper and lower separable semicircular cylinder, link together by bolt group, and final stage is straight tube, can effectively clear up like this slag charge obstruction that starts section.
