Abstract

The utility model relates to an adhesive tape anti-tearing device for a conveyor, which is mainly characterized by comprising a casing, a swinging plate, a swinging shaft, a bearing housing, bearings, a semi-ring and a proximity switch. The swinging plate is fixedly mounted on the swinging shaft, two ends of the swinging shaft equipped with the bearings are mounted in the bearing housing, the bearing housing is fixed on the casing, the semi-ring is mounted at one end of the swinging shaft, the proximity switch is mounted on a position of the casing corresponding to the semi-ring, and the swinging plate, the swinging shaft and the semi-ring rotate simultaneously. The utility model is reasonable in structure and installation, and can effectively prevent adhesive tapes to be torn longitudinally, thereby avoiding heavy accidents of equipment and economic losses caused by the heavy accidents.

Description

A kind of conveyer is prevented the adhesive tape tear device

Technical field

The utility model belongs to travelling apron, and specifically a kind of conveyer is prevented the adhesive tape tear device.

Background technology

Material blanking tube and conveyer are the common devices of generally using during bulk cargo is carried, as shown in Figure 1.Because material is from top to bottom to fall on the adhesive tape of conveyer from material blanking tube; and through deflector chute, when falling thing such as bigger stone or iron plate like this from material blanking tube, will be stuck in the inlet of deflector chute; usually can tear adhesive tape, and bring direct and indirect massive losses to production.For example: No. 9 conveyers of certain thermal power plant, be stuck in the deflector chute entrance owing to fall an iron plate from material blanking tube, adhesive tape is in running, and a few minutes reach 700 meters to longitudinal rupture of adhesive tape; Again for example: No. 4 conveyers of certain factory fall a stone from material blanking tube and are stuck in the deflector chute entrance, more than 100 meter of same longitudinal rupture of adhesive tape.

The anti-adhesive tape tear device of installing on the existing conveyer, the structure of this device is that a U-shaped sebific duct is positioned on below the adhesive tape, the inside is provided with two discontiguous copper strips, when stone or metal objects pierce through adhesive tape, the sealing-tape machine object that is in operation pierces through adhesive tape and runs into sebific duct, two copper strips contacts, and circuit is connected, conveyer shuts down, and prevents that like this adhesive tape from tearing.And this device is difficult to play the effect that anti-adhesive tape is torn in actual production process, and for this reason, the phenomenon that above-mentioned power plant adhesive tape is torn happens occasionally, and causes very big economic loss to enterprise.

Summary of the invention

Order of the present utility model is to overcome the above deficiency of the prior art and defective, and is improved, and provides a kind of structure and installation rationally, and actv. has prevented the anti-adhesive tape tear device of the conveyer of longitudinal rupture of adhesive tape.

The technical solution of the utility model is to achieve these goals:

A kind of anti-adhesive tape tear device of conveyer, it is characterized in that: comprise shell, pendulum plate, balance staff, bearing seat, bearing, semi-ring and near switch, described pendulum plate is installed on the balance staff, the double headed roller head bearing of balance staff also is contained in the bearing seat, bearing seat is fixed on the shell, described semi-ring is contained in an end of balance staff, is contained in shell apart from the corresponding position of semi-ring near switch, and described pendulum plate, balance staff and semi-ring rotate simultaneously together.

The utility model compared with the prior art, substantive distinguishing features that it is main and positive effect are: structure and installing rationally can effectively prevent longitudinal rupture of adhesive tape, the economic loss of avoiding the equipment grave accident and causing.

The specific embodiment

Be elaborated below in conjunction with accompanying drawing:

As shown in Figures 2 and 3, the anti-adhesive tape tear device of the utility model conveyer.It has shell 1 shelf of balance staff (dress), pendulum plate 2, balance staff 3, bearing seat 4, bearing 5, semi-ring 6 with near switch 7 etc., described pendulum plate is installed on the balance staff, the double headed roller head bearing of balance staff also is contained in the bearing seat, bearing seat is fixed on the shell, described semi-ring is contained in an end of balance staff, be contained in shell apart from the corresponding position of semi-ring near switch, described pendulum plate, balance staff and semi-ring rotate simultaneously together.

As shown in Figure 4, the scheme drawing of the utility model on material blanking tube and conveyer.The anti-adhesive tape tear device of conveyer is loaded on the exit of material blanking tube 8 and the entrance of deflector chute, and above the adhesive tape of conveyer 9.For anti-adhesive tape tear device is installed on material blanking tube that is moving and the conveyer, need prescind a part to the outlet of material blanking tube and deflector chute entrance, will prevent that the adhesive tape tear device lifts on the deflector chute, the corresponding and part that prescinds is alignd and is welded.

The utility model principle of work:

As shown in Figure 4, when materials such as bulk stone or iron plate 10 fall, can not directly pass through deflector chute, be bound to promote earlier pendulum plate (the same height in pendulum plate lower end) with the deflector chute loam cake, drive balance staff and semi-ring simultaneously and rotate an angle, make near switch ways, the control conveyer stops, and has avoided tearing adhesive tape.When things such as bulk stone or iron plate fall, can in deflector chute, pass through, can promote to put plate scarcely, can not rotate semi-ring yet, still open circuit the travelling apron normal operation near switch.

As shown in Figure 5, electric control theory figure of the present utility model.Electric control theory is: when big material such as bulk stone or iron plate falls at material blanking tube, if can pass through deflector chute, conveyer normally moves, and this moment is not closed near K switch, and relay J S is failure to actuate, and the close point of JS is still closed, and conveyer does as usual and works.When big material such as bulk stone or iron plate, fall at material blanking tube, if the impassabitity deflector chute, must promote to put plate and turn an angle, near the K closure, relay J S action, the normally closed point of JS disconnects, and conveyer is out of service, has avoided the serious accident of a longitudinal rupture of adhesive tape.

Claims

1, the anti-adhesive tape tear device of a kind of conveyer, it is characterized in that: have shell (1), pendulum plate (2), balance staff (3), bearing seat (4), bearing (5), semi-ring (6) with near switch (7), described pendulum plate is installed on the balance staff, the double headed roller head bearing of balance staff also is contained in the bearing seat, and bearing seat is fixed on the shell; Described semi-ring is contained in an end of balance staff, is contained in shell apart from the corresponding position of semi-ring near switch, and described pendulum plate, balance staff rotate simultaneously with semi-ring.
