Description

A kind of belt conveyor belt backstop

Technical field

The utility model is related to conveying device in a kind of industrial production, especially a kind of non-return dress of belt conveyor belt It sets.

Background technology

Belt conveyor can be used for straight feeding in industrial production, carry out many places charging or many places discharging.Due to conveying Machine can be designed according to in-situ production environment, and can be conveyed containing grey high and high temperature material, according to actual production ring The advantage that border situation is adjusted is larger, is therefore widely used in industrial production.The problem of being currently, there are mainly has：When When belt conveyor breaks down or stops suddenly, due to the gravity of the material on carrying belt, belt can be rolled with conveying Free antikinesis occurs together for cylinder, causes material to invert, can make material Severe blockage, and transmission device is made to damage, at this moment Belt conveyor can not start immediately, if started at this time, be likely to result in equipment and damaged because blocking, material is caused largely to waste While, uneasy full operation is also generated, causes the generation of safety accident, works as feed blocking, a large amount of personnel can be increased and carry out block clearing Or increase repair density, cause that the production cost increases.

Invention content

Being designed to provide for the utility model technology is a kind of simple in structure effective, and can realize prevents belt conveyor from driving Backwards rotation, protect operating personnel's personal safety and production safety, extend a kind of belt conveyor band of service life of equipment Formula backstop.

In order to achieve the above object, the utility model proposes a kind of belt conveyor belt backstop, purpose purports It is overcoming the deficiencies of existing technologies, is realizing the non-return of belt conveyor, which includes：Non-return bracket, guide roller, Guiding protecting cover, anchor bolt nut, non-return belt, non-return bracket are fixed on supporting rack, there is fixed lead on non-return bracket To roller, non-return belt is oriented to the uniform installation of protecting cover by three and is pressed on non-return bracket, and is fastened by three sets of anchor bolt nuts.

Backstop in the belt conveyor is mounted on active roll side position.

Non-return belt on the backstop is overlapped under active roll.

Guide roller on the backstop is fixed on non-return bracket, can be oriented to non-return belt and supporting role.

Guiding protecting cover on the backstop is fixed on non-return bracket, can be oriented to non-return belt and protective action.

Anchor bolt nut on the backstop first compresses non-return belt, then compresses fastening with protecting cover is oriented to.

According to the above structure, when belt conveyor active roll rotates in the forward direction, non-return belt is only overlapped on active roll Under, it does not work, when there is the reverse rotation of special circumstances belt conveyor active roll, non-return belt can be under active roll It is gradually caught under active roll with the rotation of active roll, active roll is braked and is stopped, having prevented belt conveyor actively The reverse rotation of roller.

Compared with prior art, the utility model has the beneficial effects that：It is simple in structure effective, it is easy to implement, scene is pacified Dress environmental requirement is not high, does not need too many mechanism design and can be realized as preventing inversely turning for belt conveyor driving with assembling Dynamic effect protects operating personnel's personal safety and production safety, extends service life of equipment.

The above is preferred embodiments of the present invention, it is noted that is not exhaustively or by this reality The utility model institute is not being departed from the form disclosed in novel be limited to for those skilled in the art Under the premise of stating principle, it can also make several improvements and retouch, these improvements and modifications are in order to which this practicality is better described Novel principle and practical application, and make those skilled in the art it will be appreciated that the utility model is applicable in design In the various embodiments with various modifications of special-purpose.

In Fig. 1-3：1 be active roll, 2 be belt backstop, 3 be conveyer belt, 4 be conveyer bridge, 5 for from Dynamic roller, 21 be non-return bracket, 22 be guide roller, 23 be oriented to protecting cover, 24 be fixing bolt, 25 be fixing nut, 26 until Inverse belt.

Specific implementation mode

The utility model proposes a kind of belt conveyor belt backstop, purpose is intended to overcome lacking for the prior art It falls into, realizes the non-return of belt conveyor.The belt backstop 2 includes：Non-return bracket 21, guide roller 22 are oriented to protecting cover 23, Gu Determine 24 nut 25 of bolt, non-return belt 26, non-return bracket 21 is fixed on 4 on supporting rack, there is fixed lead on non-return bracket 21 To roller 22, non-return belt 26 is oriented to the uniform installation of protecting cover 23 by three and is pressed on non-return bracket 21, and by three sets of fixing bolts 24 nuts 25 fasten.

Backstop 2 in the belt conveyor is mounted on 1 side of active roll position.

Non-return belt 26 on the backstop 2 is overlapped under active roll 1.

Guide roller 22 on the backstop 2 is fixed on non-return bracket 21, and non-return belt 26 can be oriented to and be supported Effect.

Guiding protecting cover 23 on the backstop 2 is fixed on non-return bracket 21, and non-return belt 26 can be oriented to and be prevented Shield acts on.

24 nut 25 of fixing bolt on the backstop 2 first compresses non-return belt 26, then is oriented to protecting covers with three 23 compress fastening, can play the role of certain fastening and adjust non-return belt 26, can also be oriented to shield to fasten three Lid 23.

According to the above structure, when belt conveyor active roll 1 rotates in the forward direction, direction of rotation as shown is to rotate in the forward direction, Non-return belt 26 is only overlapped under active roll 1, is not worked, anti-when there is special circumstances belt conveyor active roll 1 To when rotation, non-return belt 26 can be gradually caught in the rotation of active roll 1 under active roll 1 under active roll 1, will be led The dynamic braking of roller 1 stops, and has prevented the reverse rotation of belt conveyor active roll 1, has realized the non-return of belt conveyor.
