Abstract
The utility model relates to a safety interlocking device for a forced mixer. The safety interlocking device comprises the forced mixer (1), wherein a mixer cover (1a) is arranged at the upper end of the forced mixer, a travel switch (2) is mounted at the top of the side wall (1b) of the forced mixer, a travel switch contact (3) is mounted in a position, corresponding to the travel switch (2), of the mixer cover, the travel switch contact is contacted with the travel switchwhenthe mixer cover is in a closed state, and an electromagnetaxle-locking brake (4) is mounted on a rotating shaft (1c) of the forced mixer. According to the safety interlocking device, unsafe factors in an equipmentmaintenance process are avoided fundamentally, safety accidents caused by misoperation of equipment are avoided, and the life safety of operation and maintenance personnel can be guaranteed during equipment production operation and maintenance.
Description
Technical field
The utility model relates to forced mixer, refers in particular to, a kind of safety interlock for forced mixer.Belong to equipment operating safe practice field.
Background technology
Forced mixer is to be a kind of strong stirring equipment that different material is mixed, and is mainly used in the production fields such as metallurgical construction.Stir between shovel and cursor and adopted cross assemble to be connected, and the working clearance of pull bar or screw rod regulation and control stirring shovel is set, substantially eliminated hard ware material stuck phenomenon, reduced running resistance, reduce wear.Because forced mixer has, power is large, rational in infrastructure, simple operation and other advantages, is widely used at present the production fields such as metallurgical construction.
Existing forced mixer does not mostly have design safety interlock and emergency brake device, and Operation and Maintenance personnel are stirred machine strand wound or the event of rolling happens occasionally, and bring significant threat to life security.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safety interlock for forced mixer, can in the time that mixer cover is opened, force rotary part to stop firmly working.
The technical scheme that the utility model addresses the above problem is as follows:
For a safety interlock for forced mixer, comprise forced mixer, the upper end of described forced mixer is cover, it is characterized in that:
Described forced mixer top side wall is provided with travel switch, the position that described cover is corresponding with travel switch is provided with travel switch contact, under cover closure state, travel switch contact contacts with travel switch, and the brake of electromagnet seize is installed in the rotating shaft of described forced mixer.
Described electromagnet seize brake is arranged on the lower end of rotating shaft.
Operation principle of the present utility model is, under cover closure state, because travel switch and travel switch contact contact, control circuit is connected device start, and forced mixer is normally worked; In the time of apparatus lid opening, travel switch contact and travel switch are in contactless state, and control circuit disconnects, and plays the possibility of avoiding equipment misoperation, and electromagnet seize brake response in the time of apparatus lid opening simultaneously, forces rotary part to stop the rotation.
Compared with prior art, the beneficial effects of the utility model are:
The utlity model has simple in structure, respond fast feature, fundamentally avoid the unsafe factor in plant maintenance process, avoided the security incident that causes because of equipment misoperation, can in the time of device fabrication operation and maintenance, guarantee Operation and Maintenance personnel's life security.
Brief description of the drawings
Fig. 1 is the structural representation of prior art mixer.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the enlarged diagram of A portion in Fig. 2.
In figure: 1, forced mixer; 1a, cover; 1b, sidewall; 1c, rotating shaft; 2, travel switch; 3, travel switch contact; 4, electromagnet seize brake.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 2 and Fig. 3, a kind of safety interlock for forced mixer, comprise forced mixer 1, the upper end of described forced mixer is cover 1a, the sidewall 1b top of described forced mixer is provided with travel switch 2, and the position that described cover is corresponding with travel switch 2 is provided with travel switch contact 3, under cover closure state, travel switch contact contacts with travel switch, and electromagnet seize brake 4 is installed on the rotating shaft 1c of described forced mixer.Described electromagnet seize brake is arranged on the lower end of rotating shaft.
Operation principle of the present utility model is, under cover closure state, because travel switch and travel switch contact contact, control circuit is connected device start, and forced mixer is normally worked; In the time of apparatus lid opening, travel switch contact and travel switch are in contactless state, and control circuit disconnects, and plays the possibility of avoiding equipment misoperation, and electromagnet seize brake response in the time of apparatus lid opening simultaneously, forces rotary part to stop the rotation.
Claims (2)
1. for a safety interlock for forced mixer, comprise forced mixer (1), the upper end of described forced mixer is cover (1a), it is characterized in that:
Sidewall (1b) top of described forced mixer is provided with travel switch (2), the position that described cover is corresponding with travel switch (2) is provided with travel switch contact (3), under cover closure state, travel switch contact contacts with travel switch, and electromagnet seize brake (4) is installed in the rotating shaft (1c) of described forced mixer.
