Specific embodiment
The utility model provides a kind of brake gear of frame winch, to make the purpose of this utility model, technical solution and effect Fruit is clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that this Locate described specific embodiment only to explain the utility model, is not used to limit the utility model.
Herein, the left side in the side of 4 ' rotation direction of wheel disc, i.e. Fig. 2 is referred to after, it is preceding and rear reversed.
Please refer to Fig. 1-4, a kind of brake gear of frame winch provided by the utility model, including magnetic speed mechanism A and Friction block stop mechanism B;Magnetic speed mechanism includes multiple the first electromagnetism being circumferentially evenly spaced on frame winch wheel disc 4 ' Iron 1, the second electromagnet 2 being fixed on frame winch pedestal 1 ', and connect electrical component 3;Electrical component is connect for the second electromagnet Several first electromagnet of rear side power on, these first electromagnet mutually attract with the second electromagnet;The friction block stops Mechanism of car has friction block 4, and so that it is stopped operating by the way that friction block is pressed to wheel disc.
When brake, magnetic speed mechanism first works, and the second electromagnet is powered, if connecing electrical component on rear side of the second electromagnet Dry first electromagnet powers on, these first electromagnet and the second electromagnet are heteropolar opposite to generate suction (such as Fig. 2 institute Show), the retarding moment opposite with rotation direction is formed using the attraction between the first electromagnet and the second electromagnet, makes wheel disc Slow down, (final speed can be controlled by controlling the working time of magnetic speed mechanism) after speed reduces to a certain extent, The work of friction block stop mechanism carries out friction parking, and since the speed of wheel disc is lower, the temperature for the generation that rubs is relatively low, can It improves braking efficiency and reduces the rate of wear of friction block.
Further, first electromagnet 1 is fixed in an annular mounting groove 5, the annular mounting groove and wheel disc 4 ' It is connected;Annular mounting groove is made of nonferromagnetic material (such as aluminium, copper, stainless steel).Since annular mounting groove is by nonferromagnetic material It is made, will not be magnetized by the first electromagnet, it is ensured that the torque that the attraction between the first electromagnet and the second electromagnet generates Always opposite with rotation direction.
In the present embodiment, see Fig. 3 (Fig. 3 is side view), each first electricity is corresponded on the outer peripheral surface of the annular mounting groove 5 The position of magnet 1 is provided with one piece of cathode conductive film 6 and one piece of cathode conductive film 7, the first magnet spool both ends difference It is connected with corresponding cathode conductive film and cathode conductive film;If the electrical component 3 that connects can be simultaneously on rear side of the second electromagnet Dry cathode conductive film connects power supply with cathode conductive film.Since wheel disc needs to rotate, if existed electrical component setting is connect The inside of annular mounting groove then needs to be arranged complicated mounting structure and connects electrical component to fix;Cathode conductive film and cathode are led Electric piece is arranged on the outer peripheral surface of annular mounting groove, connects electrical component and is set up directly on pedestal 1 ', compared in inside, has Conducive to simplified mounting structure and wire structures.
Further, all cathode conductive films 6 are arranged on the same contour of annular mounting groove 5, and all cathode are led Electric piece 7 is arranged on another contour, and cathode conductive film and cathode conductive film insulate with annular mounting groove (such as in conductive sheet and ring Insulation spacer is set, and cathode conductive film and cathode conductive film are referred to as conductive sheet) between shape mounting groove;The electrical component 3 that connects includes The arc-shaped brush item 3.1 of two difference face cathode conductive films and cathode conductive film setting, and driving brush item is along ring The actuator of shape mounting groove radially moved back and forth;Two brush items are connect with the positive and negative anodes of power supply respectively, such as Fig. 3 institute Show.
When not braking, brush item is separated with conductive sheet, and when needing to brake, brush item is pressed to conductive sheet by actuator, thus Corresponding first electromagnet is set to be powered, since the circumferential position of brush item is fixed, and in the rear side of the second electromagnet, therefore It can guarantee only have several first electromagnet on rear side of the second electromagnet to be powered when brake, other first electromagnet is avoided to be powered but Significant attraction can not be generated and waste electric energy.
Specifically, the actuator includes guide sleeve 3.2, the third electromagnet 3.3 of guide sleeve bottom is set, and sliding is set The slide bar 3.4 in guide sleeve is set, the permanent magnet 3.5 of the lower end of the slider is connected to, and the attachment base at the top of slide bar is set 3.6;The brush item 3.1 is mounted on attachment base.When needing to brake, third electromagnet 3.3 is positive to be powered, at this time third electricity Magnet is opposite with permanent magnet homopolarity to generate repulsion (as shown in Figure 3), so that pushing attachment base to move up connects the first electromagnet;It reduces After the completion, third electromagnet is reversely powered, and third electromagnet and the heteropolar opposite generation suction of permanent magnet, retract slide bar at this time, The power-off of first electromagnet, at this point, third electromagnet can also power off, permanent magnet can be sucked in the iron core of third electromagnet, avoid connecting Seat is mobile, it is seen that when frame winch works normally, does not need consumption electric energy to maintain the retracted state of slide bar.
Further, the brush item 3.1 is carbon item, is detachable connection between brush item and attachment base 3.6.Due to It can rub between brush item and conductive sheet, brush item is set as carbon item herein, can avoid conduction pad wear, and carbon item is Wearing detail is replaced, therefore is set as detachable connection and is convenient for changing.In the present embodiment, opened up on attachment base 3.6 There is the mounting groove being adapted with brush item 3.1, brush item is plugged in mounting groove and locks by screw.
Preferably, arc-shaped extension 2.1 is provided at the top of the iron core of second electromagnet 2.The extension and ring Shape mounting groove 5 with one heart, can expand the expanded range of pole on the second electromagnet by the extension, shorten the first electromagnet and second The distance between electromagnet to improve total attraction, and then improves retardation efficiency.
Specifically, the friction block stop mechanism B includes two cylinders being oppositely arranged 8, and for fixing cylinder Mounting base 9;The piston rod end of each cylinder is provided with one piece of brake block 10, and friction block 4, the wheel disc are equipped on brake block It is arranged between two pieces of friction blocks.When brake, two piston rods stretch out simultaneously, and two pieces of friction blocks rub with wheel disc 4 ' simultaneously, and Each friction block respectively provides pressure by a cylinder, and pressure is larger, and frictional force is also larger, and braking efficiency is high.Since friction block is Expendable part, detachable connection between friction block and brake block, to replace.
Preferably, there are two the friction block stop mechanism B settings, the two sides of magnetic speed mechanism A are separately positioned on, with Further increase braking efficiency.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of the utility model Range.
