Description

Technical field

The technical solution relates to mechanical engineering and can be used in engines, for example, a feed unit for a shearer.

State of the art

Known, chosen as the closest analogue, is the feed unit of the KDK500 shearer, which includes a planetary gearbox, an engine with a brake mechanism, which are kinematically connected to a horizontal cylindrical gearbox of the shearer, which is equipped with an engine mount bracket, while the engine is located between the planetary gearbox and bracket .

On the obstruction side of the shearer, on the outside on the front wall of the feed unit engine, a junction box with a cable entry is made, which is closed by a lid. The cable entry is made double-sided (T-shaped) and placed together with the junction box within the transverse dimension of the motor housing.

The disadvantage of the closest analogue is that to insert the cable into the engine junction box, it is necessary to bend the cable 90 ° and then bend it 90 ° again directly in the cable entry box of the power cable core. The presence of additional cable bends significantly affects the complexity of connecting the cable to the combine, because its veins are quite rigid and require great efforts from the maintenance staff and even special tools to bend them 90 °, and the presence of the open part of the cable from the heap side of the shearer contributes to the risk of damage, which significantly affects the state of safety.

A task

To develop the design of a junction box for inputting power cables into the feed unit engine, which is more convenient for the operating personnel, as well as to protect the part of the power cables that remained open in the feed unit from the side of the heave of the shearer from damage.

As a result of solving this problem, a technical result will be obtained: reducing the complexity of bending the power cable, due to its protection from damage, from the side of the shearing part of the shearer.

Disclosure of a technical solution

In the feed unit of the shearer, which contains a horizontal cylindrical gearbox (3) with a bracket kinematically connected to a planetary gearbox (1) and mounted on a bracket (4), a motor (2), in which one end wall of the housing (8) is adjacent to a horizontal cylindrical gearbox housing (3), and a junction box (9) with a cover (10) and at least one cable entry (11) is made outside the other end wall of the housing (7), while the engine (2) is located between the planetary gearbox (1) and bracket (4), offer It turns out that part of the junction box (9) with the inlet (12a) of the channel (12) of the cable entry (11) should be extended beyond the extreme vertical plane (P) of the outer dimension of the bracket (4), with the possibility of placing the cable (13) along the bracket (4 ) within (h) the withdrawn part of the junction box (9).

The above essential features of a technical solution, different from the closest analogue, are necessary and sufficient in all cases to which the scope of legal protection of a utility model applies.

In addition, it is proposed that the axis (Y) of the channel (12) of the cable entry (11) be performed at an angle α = 45 ° to the extreme vertical plane (P).

Industrial applicability

The assembled shearer feed unit is shown in FIG. 1 and FIG. 2.

An arm (4) is fixed on the side surface of the housing of a horizontal spur gearbox (1). The planetary gearbox (3) and the motor (2) are kinematically connected with a horizontal cylindrical gearbox (1) and are installed on one side of its housing. The motor (2) is fixed to the bracket (4) by a bolt connection (14) and is installed so that its one end wall (8) is adjacent to the housing of a horizontal cylindrical gearbox (1). On the other end wall (7) of the engine (2), a junction box (9) is made with two cable leads (11), part of which is extended beyond the extreme vertical plane (P), which limits the outer dimension of the bracket (4). The brake mechanism (5) is kinematically connected with the engine (2) and mounted on the opposite wall of the housing of a horizontal cylindrical gearbox (1).

The feed block of the shearer is installed from the obstructed side into the body of the combine (6) (Fig. 1), while the part of the cable (13) necessary for connecting the motor (2) is output parallel to the extreme vertical plane (P) of the bracket (4) from the body combine (6), and the cover (10) of the junction box (9) is pre-dismantled (Fig. 4).

After introducing most of the feed unit into the combine body (6), the curved part of the cable (13) at an angle α = 45 ° (Fig. 3) is introduced by personnel through the inlet (12a) of the cable entry channel (12) (11) into the internal distribution cavity boxes (9). The angle of inclination of the axis (Y) of the channel (12) of the cable entry (11) equal to 45 ° (Fig. 3) allows the optimal clearance between the feed unit and the body of the combine (6) to allow personnel to access the inlet (12a) of the cable channel (12) input (11) and cable (13), which provides convenience for personnel when connecting the feed unit and reducing the complexity of bending the cable (13).

After the cable (13) is inserted into the cable box (9), the cores (13a) are connected to the motor throughput contacts (2) removed from the end wall (7).

Next, the cable box (9) is closed by a cover (10), which is fixed by a bolt connection and the feed unit is inserted completely into the combine body (6) (Fig. 2).

The junction box (9) within (h) its part, extended beyond the extreme vertical plane (P), blocks the connection of the cable (13) with the cable entry (11) from the obstructed side of the combine body (6) (Fig. 2 and Fig. 4 ), this allows the cable (13) not to lead out into the dam part of the combine and eliminates its damage from external impacts during the operation of the combine, resulting in improved safety conditions.
