Referring to Fig. 1 to Fig. 4, show board-like denitrating catalyst Cell suspender of the present utility model.
This board-like denitrating catalyst Cell comprises a crossbeam 4 with suspender, the two ends lower edge of described crossbeam 4 is hinged with respectively suspension hook 1, the upper end of described suspension hook 1 is articulated with described crossbeam 4 swinging, lower end is provided with outward extending hook portion, wherein, for avoiding suspension hook 1 too to inner rotary, the two ends lower edge of described crossbeam 4 is also respectively equipped with limiting stopper 2, described limiting stopper 2 is from the articulated section, upper end of described suspension hook 1 to downward-extension, to realize the rotary stopper of suspension hook.
Wherein, the middle part of described crossbeam 4 is provided with screw 7 and the assembly that hoists, the described assembly that hoists can comprise and run through spiral shell and in the screw mandrel 6 of described screw 7, the upper end of described screw mandrel 6 can be provided with rotary drive, lower end activity be sheathed with screw mandrel 6 move up and down and thereupon rotate articulated joint 8, wherein, between the lower end of described screw mandrel 6 and articulated joint 8, can coordinate to realize flexible connection by flange, as the lower end of screw mandrel 6 is provided with flange, in described articulated joint 8, be provided with the boss that coordinates described flange, thereby can make articulated joint 8 activities be resisted against described screw mandrel 6 lower end and with screw mandrel 6 move up and down and mobile, but do not rotate with the rotation of screw mandrel 6, described rotary drive can be the handle shown in Fig. 1 to carry out manual rotation driving, also can be the power drive assemblies that comprises motor and drive nut, described motor can be fixed on described crossbeam 4, its output shaft is connected to driving nut, described driving nut is sleeved on described screw mandrel 6, thereby can under the driving of motor, drive screw mandrel rotation.
The both sides of described articulated joint 8 are articulated with respectively one end of a connecting rod 9, the middle part of described connecting rod 9 respectively the hinged lower surface from crossbeam 4 to the protuberance of downward-extension, the other end is articulated with respectively the middle part of described suspension hook 1, thus, in the time that articulated joint 8 is risen or is declined, connecting rod 9, due to the point action of protuberance, will drive suspension hook 1 inwardly rotate or outwards rotate, so that the hook portion of suspension hook 1 lower end inside contracts or be overhanging.
Wherein, the upper surface both sides of described crossbeam 4 are respectively equipped with hanger 3, and described hanger 3 can be the annular element in the screw that is fixed on described crossbeam 4.
Wherein, the hook portion top of each suspension hook 1 is provided with and holds down assembly, described holding down assembly comprises screw rod 10, stay bearing plate 11 and pressing plate 13, the hook portion top outer rim of described suspension hook 1 is fixed in one end of described stay bearing plate 11, the other end laterally stretches out, described stay bearing plate 11 is provided with the inner bolt hole that screws togather perforation for described screw rod 10, the lower end of described screw rod 10 is provided with pressing plate 13, thus, by the engagement of screw rod 10 and inner bolt hole, pressing plate 13 can move up and down, and to carry out pressing between the Cell in hook portion, comes off and damages avoiding.
Wherein, also can be provided with thrust baring 12 between described screw rod 10 and pressing plate 13, the bottom of described screw rod 10 is fixed pressing plate 13 by nut 14.
Known referring to Fig. 1, described suspension hook 1, limiting stopper 2, hanger 3, connecting rod 9, screw rod 10, stay bearing plate 11, thrust baring 12, pressing plate 13, nut 14 etc. are two groups that be arranged in parallel symmetrical.
Wherein, described limiting stopper 2 can be integrally welded with crossbeam 4.The upper end of described screw rod 10 can be provided with and drive handwheel or drive motor and drive nut.Described stay bearing plate 11 is integrally welded with suspension hook 1.Motion in described pressing plate 13 horizontal surfaces is limited jointly by screw rod 10 and suspension hook 1, therefore pressing plate 13 can not rotate.
Method of operation: can articulated joint 8 risings and suspension hook 1 inwardly be shunk swinging handle 5, the hook portion that ensures suspension hook 1 can enter in board-like denitrating catalyst Cell smoothly, then make articulated joint 8 decline with by the gap of the hook portion plug-in unit case of suspension hook 1, swinging handle 5 opens suspension hook 1, until suspension hook 1 contacts with limiting stopper 2, now suspension hook 1 enters the flanging of Cell completely.Then promoting thrust baring 12 by handwheel rotary screw 10 moves downward, pressing plate 13 moves downward under the effect of thrust baring 12 simultaneously, until the flanging of clamping unit case, now Cell is just fixed on suspender completely, now just can pass through hanger 3 liftings, transhipment Cell to assigned address.
When Cell arrive assigned address, fall in place after, pull pressing plate 13 upward movements by handwheel rotary screw 10, unclamp the flanging of Cell.Then swinging handle 5 inwardly shrinks suspension hook 1, when suspension hook 1 exits after Cell flanging, just suspender can be hoisted and removes, and carries out handling work next time.
In order to ensure suspender working stability, reliable, described suspension hook, limiting stopper, hanger, connecting rod, screw rod, thrust baring, pressing plate, nut be arranged in parallel symmetrical two groups, can not cause unbalance loading.
In order to ensure the safety in handling process, described pressing plate can, by Cell flanging being pressed on suspension hook tightly, prevent the phenomenon such as slippage, unhook in handling process.
Insert and hook and unload hook operation convenience in order to improve suspender, suspender is stretched out and is retracted by handle, leading screw regulating connecting rod, and degree of regulation is high, has avoided the phenomenon such as jam of sliding lock set structure.
For fear of the lifting process suspender framework of colliding with, the overall dimensions of suspender is not more than the size of unit box.
As can be seen here, the utility model has the advantage of:
1, stretch out by lever regulated suspension hook and shrink to hook Cell flanging, making operation easier to be reliable, having improved production efficiency;
2, by utilizing the clamping structure of adjustable pressure plate, avoid too small causing of suspension hook bayonet socket in the process of flanging that is installed, to block the phenomenons such as tight, card does not enter, improve safety, the reliability of operation.
3, novel structure, reasonable, convenient operating maintenance, be conducive to the Stability and veracity that board-like denitrating catalyst Cell is installed, improve the safety and reliability of board-like denitrating catalyst Cell lifting, actv. has been avoided the damage to board-like catalyst in lifting process, thereby reduce cost, improved work efficiency.Adapt to the needs of current board-like denitrating catalyst Cell lifting.
It is evident that above description and to record be only for example instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model does not limit by accompanying drawing example and the optimal mode thought at present of conduct of describing in an embodiment to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment that falls into specification sheets above and appended claim.
