Abstract
The utility model relates to a hand angle-adjusting device with angle indication which is applied to disc balling machines of the metallurgy, the cement, the haydite and other industries. The device comprises a worm-gear and worm mechanism. A worm (3) is provided with a handle (2), and the inner hole of a worm gear (4) is provided with a screw rod (7) which is connected with a machine frame on the disc balling machine by a pin shaft (5). The end surface of the worm gear (4) is fixedly provided with an incomplete gear (14) which is engaged with a big gear (10) by a middle small gear (12), and the end surface of the big gear (10) is provided with values of the angles in marking way. An indicating needle (11) is fixed to the axle of the big gear (10). The utility model has the advantages of simple device, high reliability and accurate angle indication. Only one person operates the utility model, and the angle of the balling disc can be adjusted. Besides, the user can directly observe the angular change.
Description
The utility model patent is the manual reclining apparatus with angle indication, is mainly used in metallurgy, cement, haydite, on the pelletizer of industries such as powder metallurgy.The ball raw material of making of above-mentioned industry often fluctuates at aspects such as composition, granularity, moisture content, in order to produce best product and to boost productivity, the angle of balling disk (-sc) is adjusted at any time.Like this, the reclining apparatus of setting has become the indispensable indispensable device of disc balling machine, and especially this device of configuration then can make it more perfect in novel pelletizer.
At present, the reclining apparatus of using on disc balling machine has screw type, hydraulic jack type, click type etc.Though these devices can satisfy the needs of angle modulation, when angle modulation, operation effort can not one man operation, can not the directly variation of viewing angle in operating process, and can not self-locking, also need to add locking device.
In view of the deficiency that these reclining apparatus exist, task of the present utility model is that design is a kind of simple in structure, easy to operate, and the energy self-locking can observe directly the novel reclining apparatus that angle changes while security protection is arranged and can operate.
This task is to solve by following mode; A worm-and-wheel gear, the endoporus of worm gear (4) is a screwed hole, leading screw in the hole (7) is connected with the frame (6) of disc balling machine by bearing pin (5), imperfect gear (14) is screwed the end in worm gear (4), imperfect gear (14) is by intermediate speed pinion (12) and gear wheel (10) engagement, and the end face of gear wheel (10) engraves angle numerical value.Shake handle (2) worm gear (4) rotation and go up reciprocating at leading screw (7).And leading screw (7) is gone up swing at bearing pin (5), drives rotating shaft (9) bearing (8) swing relatively on the shell (1), and bearing (8) drives the rocker swing of balling disk (-sc) again, thereby the angle of balling disk (-sc) is changed.Simultaneously, worm gear (4) is by imperfect gear (14), and intermediate speed pinion (12) makes gear wheel (being dial) rotation, with the variation of indication angle.
Embodiment and accompanying drawing
Fig. 1 is the partial sectional view with manual reclining apparatus installation site of angle indication.
Fig. 2 is along the cutaway view of A-A line among Fig. 1
As can be seen from the figure this device has a shell (1), and worm gear (4) worm screw (3) is arranged in the shell (1), and handle (2) is arranged on the worm screw (3); The endoporus of worm gear (4) is the trapezoidal thread hole, and leading screw (7) is installed in the hole, and leading screw (7) is connected by the frame (6) of bearing pin (5) and disc balling machine; There is an imperfect gear (14) end of worm gear (4), and be screwed, imperfect gear (14) is by intermediate speed pinion (12) and gear wheel (10) engagement, one spring leaf (13) is arranged on the intermediate speed pinion (12), push down and, make spring leaf (13) play the locking arc effect of imperfect gear (14) with nut with its degree of tightness of adjusting spring leaf (13).Gear wheel is carved with angle numerical value on (10), pointer (11) be fixed on gear wheel (10) the axle on maintain static, jam nut (15) is fixed by bolts on the imperfect gear (14), and they and worm gear (4) are combined as a whole, and they also rotate thereupon when worm gear (4) rotates; Not end at leading screw (7) is provided with stop nut (16).
Gear wheel (10) is gone up the angle numerical value of carving, and is the position according to hinge, leading screw (7) length, and dial (being gear wheel) (10) designs with balling disk (-sc) angle Changing Pattern.
Imperfect gear (14) and worm gear (4) are fixed together, thereby have increased speed ratio.Imperfect gear (14) adopts measures such as little modulus, large speed ratio and tooth top are low to prevent velocity perturbation, again because manually relatively steadily, so do not influence the operating accuracy of reclining apparatus.
Jam nut (15) is provided with in order to prevent worm gear (4) from taking place to destroy, and jam nut (15) has enough intensity, and worm gear (4) is destroyed.Safety effect with the inclination maximum of restriction balling disk (-sc), is also played simultaneously in the position of stop nut (16) restriction worm gear (4), and balling disk (-sc) is caused a serious accident because of reclining apparatus breaks down.
Adopt worm-and-wheel gear to solve the self-locking problem.
Specifically describe present embodiment situation at work below, so that more fully understand the present utility model; Bearing is fixed by bolts on the balling disk (-sc) rocker, and rotating shaft on the frame and bearing (8) are gone up rotating shaft (9) and can freely be rotated as the hinge of living, and leading screw (7) is connected with bearing pin (5) with frame (6) on the pelletizer.During angle modulation, shake handle (2) (on handle, only applying the 9-15 kgf) and drive worm gear (4) rotation, drive leading screw (7) and go up swing, and the rocker swing that drags balling disk (-sc) changes the angle of balling disk (-sc) at bearing pin (5).Simultaneously worm gear (4) drives intermediate speed pinion (12) and gear wheel (10) (being dial) rotates, and pointer (11) is motionless with indicated angle number of degrees value, reach can angle modulation again can the variation of indicated angle number of degrees value purpose.
Simple in structure, the reliable operation of hand angle-adjusting device with angle indication, angle change exactly, can self-locking, save manpower, only need one man operation with regard to the angle of capable of regulating balling disk (-sc) and observe directly the variation of angle.
