Abstract
The utility model discloses a spiral conveyer for an earth pressure balanced pipe jacking machine, which comprises a gear, a pivoting support, a transmission sleeve, a screw rod sleeve, a gantry, a spiral blade, a door plate, an oil cylinder and a speed reduction box body. The gear is meshed with an outer gear of the pivoting support, an inner ring of the pivoting support is fixed on the speed reduction box body, the transmission sleeve is connected with the outer gear of the pivoting support, the screw rod sleeve is fixedly connected with the spiral blade and is also connected with the transmission sleeve, the transmission sleeve is connected with the speed reduction box body in a sealing manner, the gantry is arranged at one end of the speed reduction box body, the door plate is arranged on the gantry, and the oil cylinder is respectively connected with the door plate and the gantry. The spiral conveyer utilizes the characteristics of the pivoting support to carry out transmission and bear forces in different directions, and the axial size of the screw rod sleeve of a driving screw rod is small, so that the earth plugging effect is greatly weakened. The spiral blade is fixedly connected with the screw rod sleeve; therefore, when the screw rod is damaged, only the gantry needs to be opened to replace the screw rod sleeve and a spiral blade assembly without the opening of a speed reduction box and long-time stopping of work, thereby increasing the working efficiency.
Description
Technical field
The utility model relates to the equipment that a kind of earth pressure balance push-bench carries spoir to use, in particular a kind of earth pressure balance push-bench conveying worm.
Background technology
Carry the parts of spoir when conveying worm is the work of earth pressure balance push-bench, its effect is push-bench to be cut the spoir that gets off constantly discharge from native storehouse.
At present, the conveying worm that uses of push-bench mainly contains that belly is unearthed and be unearthed two kinds in the end.The push-bench inner space is narrow and small, and the form that belly is unearthed is unfavorable for adorning soil on the road earth-moving equipment because the position of soil outlet is low backward, uses and is limited to.The unearthed position of the conveying worm that end face is unearthed is more satisfactory, and unearthed basal area is bigger.The principle of conveying worm is that helical blade rotates in fixing cylindrical shell, material moves along blade screw, finally be discharged from, the endoporus of the conveying worm gear wheel that end face is unearthed is identical with helical feed machine drum body endoporus, helical blade directly rotates with gear wheel with the welding of gear wheel endoporus, after material enters the screw rod welding region, owing to do not have relative motion between gear wheel endoporus and blade, material can stop to move formation soil plug in this zone, hinder the discharge of material, the jacking force that can only be hampered by the material that leading portion constantly moves backward and produce is released this zone to the soil in the soil plug, goes round and begins again.Material before entering the soil plug can produce big pressure, do not enter reduction box in order to ensure material, need design the pillow block of certain-length at the gear wheel two ends, and be formed with multiple-sealed band between the casing endoporus, the axial dimension of pillow block is too short then can not to reach sealing effectiveness, so, the axial length overall of gear wheel is generally 0.8 times of screw rod helical pitch, the resistance ratios that produces is bigger, causes the casting difficulty, even can not casting.In addition, this structure, the welding helical blade can only be after gear wheel machines, the distortion meeting that causes of welding steadily brings adverse influence to sealing and transmission, the damage of helical blade or the damage of gear wheel be gear changing screw arbor assembly more all, need take whole reduction box apart during replacing, downtime is long, the maintenance cost height.
The utility model content
The utility model purpose: the purpose of this utility model is to overcome the deficiencies in the prior art, a kind of earth pressure balance push-bench conveying worm is provided, utilize the inner ring and the deceleration box of external tooth type pivoting support to fix, the effect of external gear and gear wheel equates, on external gear, connect a drive sleeve, the screw rod cover is connected with drive sleeve, and screw rod is welded on screw rod and puts.Part processing is simple, and is easy for installation, is convenient to maintenance.
Technical scheme: the utility model is achieved through the following technical solutions, the utility model comprises gear, pivoting support, drive sleeve, the screw rod cover, door frame, helical blade, door-plate, oil cylinder and deceleration box, wherein: the external gear of gear and pivoting support is meshed, the inner ring of pivoting support is fixed on the deceleration box, the external gear of drive sleeve and pivoting support links to each other, screw rod cover and helical blade are fixedly linked, the screw rod cover links to each other with drive sleeve, sealing links to each other drive sleeve with deceleration box, door frame is located at an end of deceleration box, door-plate is located on the door frame, and oil cylinder links to each other with door frame with door-plate respectively.
The external toothing bolt of described drive sleeve and pivoting support links to each other, and utilizes pivoting support to realize power transmission and the power of bearing different directions.
Described drive sleeve links to each other by the seal sealing with deceleration box.
The axial dimension of described screw rod cover is less than or equal to 0.4 times of screw rod helical pitch.
Described door frame is provided with chute, and door-plate is located in the chute of door frame, has realized door-plate in the chute of door frame, and door-plate slides up and down under the effect of oil cylinder, to open or close soil outlet.
Operating principle of the present utility model is: utilize the external tooth type pivoting support, inner ring and deceleration box are fixed, external gear and gears engaged, connect drive sleeve with bolt on the external gear, circle is welded with the screw rod cover of helical blade in connecting on the drive sleeve, be provided with seal between drive sleeve cylindrical and deceleration box and realize sealing, powerdriven approach is: motor-gear-pivoting support external gear-drive sleeve-screw rod cover-screw rod.
Beneficial effect: use the efficient that the utility model conveying worm is unearthed to improve greatly, eliminated native plug situation, it is effect improved obvious to be unearthed, simultaneously, owing to helical blade only is fixedly linked with the screw rod cover, if screw rod damages, as long as open door frame, just can change screw rod cover and helical blade assembly, not need to open reduction box, not need long-time shut-down, increase work efficiency, processing is simple, is convenient to maintenance, low cost of manufacture.
