A spring is sheathed on the pull rod, one end of the spring is arranged on the pull rod, the other end of the spring is arranged on the protection device body. The utility model has the simple structure, the assembly and maintenance is convenient. Compared with a shearing pin axle in prior art, the utility model uses the spring body over torsion protection device, the structure is reliable, the service life is long, and the maintenance is convenient, the problem that the driving mechanism is damaged for overload during the running of the mud scrapping and adsorbing machine is resolved effectively.
Description
Technical field
The utility model belongs to the protective device of inhaling the mud scraper drive unit, is specifically related to a kind of mistake and turns round protective device.
Background technology
Along with developing rapidly of industrial and agricultural production, the generation of discarded sewage and day sharp increase.Therefore, the protection environment, handle the big important task that waste gas sewage becomes current industrial and agricultural development well.Wherein, inhaling mud scraper is one of main equipment that is used for sewage disposal, and the safe and reliable use of inhaling mud scraper is the key that guarantees sewage disposal.At present, the drive unit of equipment such as various water treatments is provided with the mistake that equipment is shielded and turns round protective device and shear bearing pin.During existing problem, when shearing bearing pin and be sheared power and destroy, the shaft coupling that connects between driving wheel and the output shaft is damaged.It is short service life that this simple and easy mistake is turned round protective device; In case damage, need transposing simultaneously to shear bearing pin and shaft coupling, maintenance load is big, has influenced the speed and the quality of water treatment.
The utility model content
To be solved in the utility model is fragile when inhaling mud scraper drive unit overload, and has short, the problem such as maintenance load is big in protective device service life of turning round now; A kind of long service life is provided, and the easy-to-install scraping and sucking machine is crossed and is turned round protective device.
The technical solution of the utility model realizes with following method:
A kind of scraping and sucking machine is crossed and is turned round protective device, comprising connecting draws ear I to draw ear II with being connected, connect and draw ear II to connect the protective device body, in the protective device body pull bar is set, ear I is drawn in the connection of pull bar one end, connects to draw ear I to connect torque plate, on the described protective device body sidewall fluting is set, collision block is set in the fluting, and collision block one end is arranged in the hole on the pull bar; Be arranged with spring on the described pull bar, spring one end is arranged on the pull bar, and the spring other end is arranged on the protective device body.
Described connection is drawn between ear I and the torque plate and is connected by bearing pin.
Described hole is an internal thread hole, and described collision block one end is the collision block of the external screw thread shape that matches with internal thread hole.
Connection of the present utility model is drawn between ear I and the torque plate by bearing pin and is connected, connect draw between ear II and the protective device body, pull bar all is threaded simple in structure, assembling and easy to maintenance with being connected to draw between the ear I; With shear pin axial ratio of the prior art, the utility model adopts spring body to cross and turns round protective device, reliable in structure, long service life, and easy to maintenance has solved the problem that mud scraper is in operation and causes driving mechanism to damage because of overload of inhaling effectively.

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic;
Fig. 3 is the schematic diagram of pull bar of the present utility model;
Fig. 4 is the cross-sectional schematic of protective device body of the present utility model;
Fig. 5 is that the B-B of Fig. 4 is to cross-sectional schematic.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; the utility model comprises connecting and draws ear I 5 to draw ear II 4 with being connected, and connects and draws ear II 4 to connect protective device bodies 8, and pull bar 10 is set in the protective device body 8; ear I 5 is drawn in the connection of pull bar 10 1 ends, connects to draw ear I 5 to connect torque plate 2.Fluting 7 is set on described protective device body 8 sidewalls, and fluting is provided with collision block 1 in 7, and collision block 1 one ends are arranged in the hole 6 on the pull bar 10; Be arranged with spring 9 on the described pull bar 10, spring 9 one ends are arranged on the pull bar 10, and spring 9 other ends are arranged on the protective device body 8.
Described connection is drawn between ear I 5 and the torque plate 2 and is connected by bearing pin 3.
Described hole 6 is internal thread holes, and described collision block 1 one ends are collision blocks of the external screw thread shape that matches with internal thread hole.
Torque plate 2 described in the utility model is by being bolted on the reducing motor, and when inhaling mud scraper work, reductor is subjected to a reaction force, the decrement of control spring 9.When equipment runs into fortuitous event.Too thick as sedimentation basin mud, when perhaps having the drive unit bearing of obstacle to destroy under the road wheel, the torsion of reducing motor increases, and drives pull bar 10 holddown springs 9, and drives collision block 1 operation, and collision block 1 can be mobile in fluting 7.On-the-spot in service according to torque and actual conditions, cross during use to turn round two travel switches are set on the protective device, when bumping against first travel switch, promptly crosses when turning round the position collision block 1, and equipment sends signal, begins to report to the police; If moment of torsion continue to increase, when collision block 1 bumps against second travel switch and is the overload protection position, device powers down, it is out of service to inhale mud scraper, reaches the purpose of protection equipment.
Mistake of the present utility model is turned round protective device and was provided with and turns round protection and transship automatic power-off protection double action.When equipment cross turn round warning after, administrative staff can search reason under non-stop-machine situation, remove obstacle, and equipment is normally moved.
