Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a mining machinery's pulley bracket, includes support 1, and the inboard of support 1 is seted up flutedly, and the inboard of support 1 is provided with installation component 2, is provided with auxiliary assembly 3 on the installation component 2, and installation component 2 is including installation piece 21, and installation piece 21 slidable mounting is in the inboard of support 1 inboard recess. The top of installation piece 21 is fixed with the one end of spring A22, the other end of spring A22 is fixed in the inboard of support 1 inboard recess, the one side that support 1 was kept away from to installation piece 21 is seted up flutedly, be fixed with dead lever 23 on the inner wall of installation piece 21, dead lever 23 runs through inserted bar 24 and with inserted bar 24 sliding connection, one side that inserted bar 24 is close to dead lever 23 is fixed with the one end of spring B25, the other end of spring B25 is fixed on the inner wall of installation piece 21, the draw-in groove has been seted up at the top of inserted bar 24, realize spacing or relieve spacingly to inserted bar 24 through cooperation gag lever post 33, when inserted bar 24 no longer by spacing, inserted bar 24 can rotate right under the effect of spring B25 and insert in the recess on the fixed axle of pulley, realize fixing the fixed axle, the pulley is run through by the fixed axle and is connected with the fixed axle rotation.

In this embodiment, the auxiliary assembly 3 includes a sliding plate 31, the sliding plate 31 is slidably mounted inside the groove of the mounting block 21, the top of the sliding plate 31 is fixed to one end of a spring C32, the other end of a spring C32 is fixed inside the groove of the mounting block 21, a top stop lever 33 of the sliding plate 31 is fixed, the stop lever 33 penetrates inside the groove of the mounting block 21 and is slidably connected to the mounting block 21, a through hole is formed in the sliding plate 31 for allowing the elastic sheet 4 to move, a control lever 34 penetrates through the top of the mounting block 21 and is slidably connected to the mounting block 21, the bottom of the control lever 34 is hinged to one end of a support lever 35, the other end of the support lever 35 is hinged to the top of the insert lever 24, when the sliding plate 31 is supported by the fixed shaft of the pulley to move upward, the sliding plate 31 drives the stop lever 33 to move upward, the stop lever 33 withdraws from the slot at the top of the insert lever 24, so as to release the stop of the insert lever 24, at this time, the fixed shaft of the pulley is not pushing upward, the pulley fixing shaft moves to the position of the arc-shaped groove of the elastic sheet 4 under the pushing of the sliding plate 31 and the spring C32, and at the moment, the elastic sheet 4 can limit the pulley fixing shaft, so that the pulley fixing shaft cannot move downwards.

In this embodiment, the inboard of installation piece 21 recess is fixed with flexure strip 4's top, the arc recess has been seted up to one side that flexure strip 4 is close to installation piece 21 center, flexure strip 4 passes the through-hole on slide 31, flexure strip 4 is the iron sheet, self possesses certain elastic coefficient and can take place the deformation of certain degree, when inserting the pulley from installation piece 21 recess, the fixed axle of pulley can support to make flexure strip 4 take place the deformation of certain degree and can give a tight power of clamp of fixed axle of pulley simultaneously under the elastic action of self at flexure strip 4 on flexure strip 4, play the effect of direction.

During operation (or during the use), when installing the pulley, aim at two sets of installation pieces 21 with the pulley, insert the fixed axle of pulley in the recess on installation piece 21, the fixed axle of pulley supports makes flexure strip 4 produce the deformation of certain degree on flexure strip 4, and supplementary staff installs.

When the fixed shaft of the pulley moves to the position of the sliding plate 31, the pulley is continuously pushed upwards, the fixed shaft of the pulley supports the sliding plate 31 to move upwards, and the sliding plate 31 drives the limiting rod 33 to move upwards, so that the limiting rod 33 is withdrawn from the clamping groove at the top of the inserted rod 24, and the limitation on the inserted rod 24 is relieved.

Meanwhile, the pulley is loosened, the sliding plate 31 pushes the fixed shaft of the pulley to move downwards under the action of the spring C32, when the fixed shaft of the pulley moves to the position of the arc-shaped groove of the elastic sheet 4, the fixed shaft of the pulley is separated from the sliding plate 31 and is clamped by the elastic sheet 4, and at the moment, under the action of the spring B25, the inserted rod 24 extends out of the mounting block 21 and is inserted into the reserved groove on the fixed shaft of the pulley, so that the mounting of the pulley is completed.

When the pulley needs to be disassembled, the control rod 34 only needs to be pushed downwards, the control rod 34 pushes the inserting rod 24 to move leftwards through the supporting rod 35, when the clamping groove in the top of the inserting rod 24 moves to the position of the limiting rod 33, the limiting rod 33 limits the inserting rod 24, and the pulley is pulled downwards at the moment and is taken down.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
