Abstract
The utility model discloses an improved belt tensioning device which adjusts tightness degree of a belt through a screw rod adjusting device of a driven roller. The screw rod adjusting device is mainly composed of a screw rod which is erected between a T-shaped bearing seat and a fixed supporting block. A nut on the screw rod adjusts effective length of the screw rod, and the fixed supporting block of the screw rod adjusting device is in a split structure and composed of an upper half block and a lower half block. The lower half block is fixed on a side plate of a rack, and the upper half block and the lower half block are fixed into a whole through a bolt. The integrated fixed supporting block is provided with a screw rod penetrating hole corresponding to the position of the screw rod. When the belt tensioning device needs to be dismantled, only the upper half block of the fixed supporting block needs to be dismantled, and consequently the screw rod can be pulled out, and sufficient maintenance space is relieved. Compared with the prior art, the improved belt tensioning device greatly improves maintenance strength of a device, saves working time, and improves working efficiency.
Description
Technical field
The utility model relates to a kind of improvement of belt stretcher.
Background technology
Load-transfer device has a wide range of applications in commercial production, generally regulates the elasticity of belt by the screw mandrel control apparatus of driven roll.Five nuts generally are housed on the screw mandrel of screw mandrel control apparatus, are respectively applied to the effective length of fixing T-shaped bearing seat, fixed doctor and adjusting screw mandrel.When maintenance relates to screw mandrel adjusting portion timesharing (as changing screw mandrel, changing scraper etc.), after 5 nuts need to being pulled down fully, screw mandrel can be pulled out from the hole of fixed support piece.Because screw mandrel adjusting place position is narrow and small, spanner is pulled the nut difficulty, and maintenance capacity is large, wastes time and energy.
The utility model content
For the deficiencies in the prior art part, the utility model provides a kind of improved belt stretcher.Screw mandrel and nut easy accessibility after improving, a little repair is time saving and energy saving.
For achieving the above object, technical solutions of the utility model are:
Improved belt stretcher, this belt stretcher is regulated the elasticity of belt by the screw mandrel control apparatus of driven roll, the screw mandrel control apparatus mainly is erected between a T-shaped bearing seat and the fixed support piece by a screw mandrel and forms, and the nut on the screw mandrel is regulated the effective length of screw mandrel.The fixed support piece of screw mandrel control apparatus is by upper and lower two Split type structures that half block forms, second piece is fixed on the framework lateral plate, upper and lower two pieces are bolted and are integrated, and the corresponding screw mandrel of the fixed rack piece that is fixed as one position forms a screw mandrel and penetrates the hole.
The usefulness of technique scheme is:
It is little that the fixed support piece of the utility model Split type structure has solved screw mandrel adjusting place maintenance time space, maintenance difficult, the problem that maintenance capacity is large.When needs are dismantled belt stretcher, only need pull down first piece of fixed support piece, screw mandrel can be pulled out, thereby discharge the service clearance of capacity.Compared with prior art, after the improvement larger reduction maintenance of equipment intensity, saved work-hours, improved work efficiency.
Description of drawings
Fig. 1 is the utility model belt stretcher structural representation;
Fig. 2 is structural representation after the dismounting of the utility model fixed support piece;
Fig. 3 is structural representation after the combination of the utility model fixed support piece.
The specific embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
Improved belt stretcher as shown in Figure 1, this belt stretcher are regulated the elasticity of belt by the screw mandrel control apparatus of driven roll 1.The screw mandrel control apparatus mainly is erected between a T-shaped bearing seat 2 and the fixed support piece 6 by a screw mandrel 4 and forms.T-shaped bearing seat 2 is by one group of nut captive joint driven roll, and another group nut on the screw mandrel is used for fixing scraper 3, and another nut of the fixed support piece 6 that reclines on the screw mandrel 4 is the effective length of regulating screw mandrel 4, to realize the elasticity control to belt.
Shown in Fig. 2,3, the fixed support piece 6 of screw mandrel control apparatus that is characterised in that of the present utility model is by upper and lower two half blocks 61,62 Split type structures that form.As shown in Figure 2, second piece 62 is welded on the framework lateral plate 9, and upper and lower two pieces 61,62 are fixed as one by bolt 8.As shown in Figure 3, the fixed rack piece 6 corresponding screw mandrel positions that are fixed as one form a screw mandrel and penetrate hole 7.
When needs are dismantled belt stretcher, only need pull down first piece 61 of fixed support piece 6, screw mandrel 4 can be pulled out, thereby discharge the service clearance of capacity.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; but according to the technological thought that the utility model proposes, any change of doing on the technical scheme basis all falls within the utility model protection domain.
