Description

An overload protection device for a sintered single-toothed roller crusher

technical field

The utility model relates to equipment for a sintered single-toothed roller crusher, in particular to an overload protection device for a sintered single-toothed roller crusher.

Background technique

The sintering single-toothed roller crusher is one of the key equipment for metallurgical sintering production. The single-toothed roller crusher is mainly composed of a motor, a reducer, a geared coupling and a single-toothed roller. It is located at the end of the main machine of the sintering machine. When the equipment is running, The motor drives the single-toothed roller to rotate through the deceleration of the reducer, which mainly plays the role of crushing sintered ore, but occasionally due to being stuck by sundries, such as the falling of the end iron, the single-toothed roller crusher is forced to stop rotating, instantly forming a huge If the motor is equipped with a large torque, the gear of the reducer will be pushed out of the casing before the motor overload protection is activated, or it will be damaged to varying degrees. Reduce output while increasing equipment and spare parts costs.

Contents of the invention

The purpose of the utility model is to provide an overload protection device for a sintered single-toothed roller crusher which has a simple structure and a reasonable design and can prevent damage to the reducer.

In order to achieve the above object, the utility model adopts the following technical solutions:

An overload protection device for a sintered single-toothed roller crusher, comprising coupling bolts and bolt sleeves, and the outer sides of the coupling bolts are covered with bolt sleeves.

The middle part of the screw rod of the coupling bolt is provided with an overload protection annular groove, the upper part of the overload protection annular groove is a square ring, the lower part is a semicircular ring, the width of the square ring is 2.2-3.8 mm, and the depth of the square ring is 0.5-2.8 mm.

Compared with the prior art, the beneficial effects of the utility model are:

An overload protection device for a sintered single-toothed roller crusher, which has the characteristics of simple structure, reasonable design, and strong practicability. Since an overload protection annular groove is provided in the middle of the screw rod of the coupling bolt, when an accident occurs to the equipment, the single-toothed roller is broken When the motor is forced to stop rotating and the motor cannot be stopped quickly, a huge torque is formed instantly to force the coupling screw to disconnect at the position of the overload protection annular groove, thereby preventing damage to the reducer. At the same time, there are bolts on the outside of the coupling bolts The sleeve is used to fix the screw and ensure that the screw is disconnected at the position of the overload protection annular groove within a certain period of time, which ensures the production needs and improves the working efficiency.

Detailed ways

The specific embodiment of the utility model is further described below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, the utility model is an overload protection device for a sintered single-toothed roller crusher, which includes a coupling bolt 11 and a bolt sleeve 13, and the outer side of the coupling bolt 11 is covered with a bolt sleeve 13. The middle part of the screw of the coupling bolt 11 is provided with an overload protection annular groove 15. The upper part of the overload protection annular groove 15 is a square ring, and the lower part is a semicircular ring. The width of the square ring is 2.2-3.8 mm, and the depth of the square ring is 0.5 ~2.8mm.

As shown in Figure 3 and Figure 4, when using the utility model, first use the coupling bolt 11, spring pad 12, bolt sleeve 13 and nut 14 to connect the reducer coupling flange 7 and the single tooth roller coupling The flanges 8 are connected together, and then the reducer outer gear 5, the reducer inner gear jacket 6, the reducer coupling flange 7, the single-gear roller coupling flange 8, the single-gear roller inner gear jacket 9 and the single-gear roller The toothed roller outer teeth 10 are assembled in the single-toothed roller toothed coupling 3, and the motor 1, the reducer 2, the single-toothed roller toothed coupling 3 and the driving single-toothed roller crusher 4 are connected together, and the operating device, among them Bolt sleeve 11 is used as an auxiliary fixing device. When encountering foreign objects or partial overburning of sintered ore, etc., it will block and drive the single-toothed roller crusher 4, preventing the operation of the driven single-toothed roller crusher 4, and driving the single-toothed roller crusher. 4 is forced to stop rotating. When the motor 1 cannot be stopped quickly, the single-toothed roller crusher 4 is driven to form a huge torque in an instant to force the coupling screw 11 to disconnect at the overload protection annular groove 15, thus ensuring the single-toothed drive. The toothed roller crusher 4 is intact.

The above is only the basic principle of the utility model, and does not limit the utility model in any way. All equivalent changes and modifications according to the utility model are within the scope of the technical protection scheme of this patent.
