Abstract
The utility model discloses a kind of lower part of a bucket-typed elevator, including a lower box body and a tensioning device of the lower axis. The utility model is characterized in that the tensioning device of the lower axis is placed in the lower box body; the tensioning device of the lower axis is composed of two parallel guide rails connected closely with the lower box body, the sliding rail moving along each guide rail, a tensioning framework connected closely with the upper part of the sliding rail, a rack pair of the gear wheel connected with each guide rail and sliding rail, and a bend wheel or bend pulley arranged on the lower part of the sliding rail; the bend wheel or bend pulley is installed on the lower axis connected with the sliding rail. With the use of the above structure, after the two ends of the lower axis is installed and adjusted, the sliding rail can be simultaneously kept moving on the guide rail all the time, ensuring that the chain or conveyor belt runs according to the track; the device effectively prevents the doffing of the chain or the deviation of the conveyor belt and the accident of breaking the chain or the belt which may be caused. The sealing door completely encloses the tensioning device of the lower axis in the lower box body, to achieve the purpose of sealing and environmental protection.
Description
Technical field
The utility model relates to bucket elevator, especially relates to the bucket elevator lower device.
Background technology
Along with bucket elevator being extensive use of of industries such as building materials, metallurgy, chemical industry, coal, electric power, grain, light industry, and the needs of environmental protection, now urgent for the improvement day of bucket elevator lower device.China Patent No. is to have mentioned the afterbody casing of body lower end in 98210388.3 the patent document, this device is that the tailing axle device is housed on the afterbody casing, the tailing axle device adopts screw rod tensioning or screw rod to add the tightening device of gravity tension type, at casing outside installing sealing arrangement, closing plate and lower shaft together along with the elongation of chain or load-transfer device along the tank surface slippage.It exists deficiency to be, because of no synchronization steering device, easily causes chain or load-transfer device to take off chain or sideslip, the equipment failure rate height.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and operate steadily, safe and reliable bucket elevator lower device.
Solve this technical problem, the technical solution of the utility model is: a kind of bucket elevator lower device, comprise lower part box and lower shaft tightening device, described lower shaft tightening device is positioned at lower part box, by with two of the lower part box captive joint parallel guide rails, the slide rail that moves back and forth along each guide rail, the tensioning frame of captiveing joint with slide rail top, be connected in the rack-and-pinion on each guide rail and the slide rail, the bend wheel or the changed course cylinder that are positioned at the slide rail bottom are formed, described bend wheel or changed course cylinder be installed on slide rail bonded assembly lower shaft on.
The arranged outside of described lower part box has hermatic door.
The gear of described rack-and-pinion is fixed in the middle part of guide rail, is fixed in the middle part of slide rail with the tooth bar of gear mesh.
The bottom of described each slide rail is connected with plain bearing, and the two ends of described lower shaft are provided with the axle sleeve that matches with described plain bearing.
Described bend wheel or changed course cylinder and lower shaft socket.
Compared with prior art, the utlity model has following advantage:
1, operate steadily, safe and reliable, equipment failure rate reduces greatly.Because the lower shaft tightening device has adopted the rack-and-gear transmission, make the lower shaft two ends after adjustment is installed, remain slide rail same moved further on guide rail, thereby guaranteed that chain or belt conveyor move by track, prevented to take off chain or belt conveyor sideslip effectively, and chain rupture that may cause thus or broken belt accident.
2, good airproof performance improves environment.Because hermatic door all is enclosed in the lower shaft tightening device in the lower part box, reach the purpose of sealing and protection environment.
3, the lower device very little maintenance, high temperature resistant, the life-span is long.Because gear, tooth bar and the plain bearing of lower shaft tightening device all have high-wearing feature, the characteristics that need not lubricate, its long service life, the user has removed the frequent worry of lubricating and keeping in repair from, has saved service expenditure.

The specific embodiment
As shown in Figure 1, bucket elevator lower device of the present utility model, it mainly is made up of lower part box 1, lower shaft tightening device 2, hermatic door 3.The arranged outside of lower part box 1 has hermatic door 3.Lower shaft tightening device 2 is connected adjustment by its guide rail with lower part box 1 after, with hermatic door 3 and lower part box 1 sealing.
Upper lateral part at Fig. 2 lower part box 1 has inlet point 4, and the bottom of inlet point has residue-removing door 5, and opposite side has access opening 6, is convenient at ordinary times clear material and I﹠M.
The lower shaft tightening device 2 of Fig. 3 is made up of guide rail 7, slide rail 8, tensioning frame 9, tooth bar 10, gear 11, plain bearing 12, axle sleeve 13, lower shaft 14, bend wheel 15 or changed course cylinder.The two ends of tensioning frame 9 are fixed on the top of slide rail 8, carry out counterweight by interior dress pouring weight; Gear 10 is fixed on the middle part of guide rail 7, and tooth bar 11 is fixed on the middle part of slide rail 8, makes slide rail 8 along guide rail 7 synchronization-slidings; Plain bearing 12 is fixed on the bottom of slide rail 8, and bend wheel 15 is enclosed within on the lower shaft 14, and the axle sleeve 13 by lower shaft 14 two ends cooperates with plain bearing 12.
Principle of work of the present utility model: by be fixed on the tensioning frame 9 on the slide rail 8 and be contained in guide rail 7 respectively and slide rail 8 on gear 11 and tooth bar 10, be connected changed course and syn tensioning by being contained in lower shaft 14 two ends plain bearings 12 with chain or belt conveyor by bend wheel 15, operate steadily, safe and reliable, equipment failure rate reduces greatly.Because gear 11, tooth bar 10 and plain bearing 12 and axle sleeve 13 all have high-wearing feature, need not lubricate.Thereby make hermatic door 3 lower shaft tightening device 2 all could be enclosed in the lower part box 1, reach the purpose of sealing and protection environment.
