DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0028] The first embodiment of the present application is:

[0029] See also Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of a direct-driven permanent magnet electric drum device. Figure 2 yes Figure 1 A magnified image of Figure 3 It is a schematic diagram of the structure with the insertion frame 109 removed.

[0030] The present invention provides a direct-driven permanent magnet electric drum device, comprising a frame 101, a drum body 102, a driving box 103 and a working device, wherein the brake assembly comprises a matching ring 104, a mounting seat 105, a clamping bracket 106, a contact member, a driving member, a linkage member and a locking member, wherein the matching ring 104 is provided with a friction contact surface 107 and a locking groove 108, the contact member comprises an insertion frame 109, a mounting bolt 110 and a rubber wiper 111, and the driving member comprises a push screw 112 and a sleeve gear 113. The above-mentioned scheme solves the problem that when the drum is braked by the friction generated between the rubber pad and the brake ring, since only one side of the drum can be braked, the permanent magnet electric drum lacks stability during the braking process, and the side that is not braked is prone to generate torque under the action of inertia, and the long-term existence of torque is prone to affect the service life of the permanent magnet electric drum.

[0031] In this embodiment, the drum body 102 is installed on one side of the frame 101, and the drive box 103 is installed on one side of the frame 101. The drive box 103 provided in conjunction with the drum body 102 is an existing direct-driven permanent magnet electric drum, and a corresponding motor drive mechanism is provided inside the drive box 103 to facilitate driving the drum body 102 installed on the frame 101.

[0032] The two matching rings 104 are respectively mounted on both sides of the drum body 102, and the matching rings 104 are provided with a friction contact surface 107 and a locking groove 108, wherein the friction contact surface 107 is located outside the end surface of the matching ring 104, and the locking groove 108 is located on the outer ring of the matching ring 104, and the two mounting seats 105 are mounted on both sides of the frame 101, and the two clamping brackets 106 are respectively and correspondingly slidably mounted on the two mounting seats 105, the contact member is connected to the clamping bracket 106, the driving member is connected to the clamping bracket 106, the linkage member is connected to the frame 101, and the locking member is connected to the mounting seat 105 is connected, the insertion frame 109 is slidably connected to the clamping bracket 106 and is located on one side of the clamping bracket 106; the mounting bolt 110 is threadedly connected to the clamping bracket 106 and passes through the insertion frame 109; the rubber wiper 111 is fixedly connected to the insertion frame 109 and is located on a side of the insertion frame 109 close to the matching ring 104, and two matching rings 104 are installed on both sides of the roller body 102 by bolts, and the outer side of the matching ring 104 is provided with the friction contact surface 107 for friction braking cooperation, and the inner side of the inner ring of the matching ring 104 is also provided with the clamping member for cooperating with the stuck member Dead groove 108, a total of two mounting seats 105 are installed on both sides of the frame 101 by bolts, and the clamping bracket 106 is slidably installed on the supporting boss of each mounting seat 105. The clamping bracket 106 is composed of a "U"-shaped member on the rear side and a placement slot plate on the front side. The insertion frame 109 cooperates with the placement slot plate on the front side of the clamping bracket 106. A through hole for the installation of the mounting bolt 110 is provided on the top plate of the insertion frame 109. The placement slot plate on the front side of the clamping bracket 106 is also provided with a threaded hole for the installation of the mounting bolt 110 at a position that cooperates with the top plate of the insertion plate, so that the user can install it through the installation The insertion frame 109 is installed on the clamping bracket 106 by bolts 110, and the rubber wiper 111 is fixedly provided on the side of the insertion frame 109. When the clamping bracket 106 drives the insertion frame 109 to slide toward the matching rings 104 provided on both sides of the roller body 102, the rubber wiper 111 will cooperate with the friction contact surface 107 provided on the matching ring 104, thereby braking the roller body 102. By using the mounting bolts 110 to quickly install the insertion frame 109 and the clamping bracket 106, the user can conveniently disassemble and replace the insertion frame 109 and the rubber wiper 111.

[0033] Secondly, the pushing screw 112 is threadedly connected to the clamping bracket 106 and is rotatably installed on one side of the mounting seat 105; the sleeve gear 113 is fixedly connected to the pushing screw 112 and sleeved on the pushing screw 112, and the pushing screw 112 is adapted to the threaded hole provided on the "U"-shaped part on the rear side of the clamping bracket 106, and the outer end of the pushing screw 112 is fixedly sleeved with the sleeve gear 113. When the sleeve gear 113 is rotated through the corresponding mechanism, the pushing screw 112 can be rotated under the drive of the sleeve gear 113, thereby driving the clamping bracket 106 to drive the insertion frame 109 and the rubber wiper 111 to cooperate with the matching ring 104.

[0034] When a direct-driven permanent magnet electric roller device of this embodiment is used, the two sets of sleeve gears 113 and the pushing screws 112 provided on the two mounting seats 105 are synchronously driven through the provided linkage components, so that the pushing screws 112 on both sides can drive the corresponding clamping brackets 106 to drive the insertion frame 109 and the rubber wiper plates 111 to cooperate with the matching rings 104 on both sides of the roller body 102. In this way, the braking of the roller body 102 can be completed by cooperating with the friction contact surfaces 107 provided on the matching rings 104 on both sides of the roller body 102. During the braking process, due to the pushing screws on both sides, 112 and the sleeve gear 113 can simultaneously drive the clamping bracket 106, the insertion bracket 109 and the rubber wiper 111 to move under the action of the linkage component. Therefore, the matching rings 104 on both sides of the roller body 102 can simultaneously cooperate with the rubber wipers 111 on both sides, so that the force is more uniform when braking the roller body 102, and the friction brake formed by the rubber wipers 111 on both sides can more quickly and stably decelerate the roller body 102, thereby achieving a more stable and effective braking of the roller through the provided components, avoiding the situation where the roller is affected by uneven force during braking and affecting the subsequent normal service life.

[0035] Second embodiment:

[0036] See also Figure 4 and Figure 5 , Figure 4 FIG. 1 is a schematic diagram of the overall structure of a direct-driven permanent magnet electric drum device according to the second embodiment. Figure 5This is a structural schematic diagram of a rotating cylinder 202 cut open. The linkage component provided by the present invention includes a fixed plate 201, a rotating cylinder 202, a connecting component and a driving component. The connecting component includes a sliding connecting rod 203, a connecting gear 204 and a toothed chain 205. The driving component includes a fixed toothed ring 206, a driving gear 207 and a driving motor 208.

[0037] The fixed plate 201 is connected to the frame 101 and is located on one side of the frame 101; the rotating cylinder 202 is rotatably connected to the fixed plate 201 and is located on one side of the fixed plate 201; the connecting component is connected to the rotating cylinder 202; the driving component is connected to the rotating cylinder 202, the sliding connecting rod 203 is connected to the rotating cylinder 202 and is rotatably mounted on the mounting seat 105; the connecting gear 204 is fixedly connected to the sliding connecting rod 203 and is sleeved on one side of the sliding connecting rod 203; the two sides of the tooth chain 205 are respectively sleeved on the connecting gear 204 and the sleeve gear 113, The fixing plate 201 is fixed to the frame 101 by bolts, and the fixing plate 201 is arranged between the two mounting seats 105. The rotating cylinder 202 is rotatably mounted on the plate, and the sliding connecting rods 203 are arranged on both sides of the rotating cylinder 202. The sliding connecting rods 203 cooperate with the hexagonal guide grooves on the inner side of the rotating cylinder 202 through the hexagonal platform arranged on the inner side. In this way, when the rotating cylinder 202 rotates, most of the sliding connecting rods 203 installed on both sides of the rotating cylinder 202 will rotate at the same time. At the same time, due to the cooperation between the hexagonal platform and the hexagonal guide groove, the sliding connecting rods 203 slide on the rotating cylinder 202 according to the actual situation. The user can adjust the installation position and spacing of the fixing plate 201 and the mounting seats 105 on both sides of the fixing plate 201 according to actual conditions. The two sliding connecting rods 203 are fixedly sleeved with the connecting gears 204. The connecting gears 204 and the sleeve gears 113 on both sides are connected by the toothed chain 205. In this way, when the rotating cylinder 202 rotates, the sliding connecting rods 203 on both sides can cooperate with the toothed chain 205 through the connecting gears 204 to synchronously drive the sleeve gears 113 on both sides. It should be noted that since the rotation directions of the sliding connecting rods 203 on both sides are consistent As a result, the rotation directions of the sleeve gears 113 and the push screws 112 on both sides are also consistent. Therefore, in order to enable the two push screws 112 to simultaneously drive the corresponding clamping brackets 106 and the insertion bracket 109 and the rubber wiper 111 to contact and cooperate, the thread rotation directions of the two push screws 112 arranged on the two mounting seats 105 are opposite, so that when the clamping bracket 106 on one side slides toward the matching ring 104 through the push screw 112 on the corresponding side, the clamping bracket 106 on the other side can also slide toward the matching ring 104 through the push screw 112 on the corresponding side.

[0038] Secondly, the fixed gear ring 206 is fixedly connected to the rotating cylinder 202 and is sleeved on the rotating cylinder 202; the driving gear 207 is meshed with the fixed gear and is rotatably installed on one side of the fixed plate 201; the output shaft of the driving motor 208 is connected to the driving gear 207, and the driving motor 208 is fixedly installed on one side of the fixed plate 201 of the frame 101. The fixed gear ring 206 is fixedly sleeved on the rotating cylinder 202, and the driving gear 207 is rotatably set on the boss set on the fixed plate 201. The output shaft of the driving motor 208 is fixed to the driving gear 207. When the driving motor 208 drives the driving gear 207 to rotate, the driving gear 207 can drive the rotating cylinder 202 by cooperating with the fixed gear ring 206.

[0039] When using a direct-driven permanent magnet electric roller device of the present embodiment, the driving gear 207 can be driven to rotate by driving the motor 208, and then the fixed gear ring 206 and the rotating cylinder 202 can be driven to rotate by the driving gear 207. When the rotating cylinder 202 rotates, the sliding connecting rods 203 on both sides of the rotating cylinder 202 will drive the corresponding connecting gears 204 to rotate, and then the sleeve gears 113 and the pushing screw 112 on both sides can be synchronously driven by the synchronous rotation of the sliding connecting rods 203 on both sides in conjunction with the connecting gears 204 and the toothed chain 205, thereby completing the synchronous driving of the clamping brackets 106 on both sides, so that when the roller body 102 is clamped and braked, the force on both sides of the matching ring 104 is more uniform and stable, which greatly enhances the practicality of the entire device.

[0040] Third embodiment:

[0041] See also Figures 6 to 8 , Figure 6 FIG. 1 is a schematic diagram of the overall structure of a direct-driven permanent magnet electric drum device according to a third embodiment. Figure 7 yes Figure 6 The enlarged view of point B, Figure 8 It is a schematic diagram of the installation structure of the rotating motor 310. The locking component provided by the present invention includes a support platform 301, a speed measuring box 302, a speed measuring wheel 303, a guiding component and a matching component. The guiding component includes a guide column 304 and an extrusion spring 305. The matching component includes a dispensing frame 306, a locking frame 307, an ejection spring 308, a rotating baffle 309, a rotating motor 310 and a controller 311.

[0042] Among them, the support platform 301 is fixedly connected to the mounting seat 105 and is located on one side of the mounting seat 105; the speed measuring box 302 is connected to the support platform 301 through the guide component and is located on one side of the support platform 301; the speed measuring wheel 303 is connected to the speed measuring box 302 and is located on a side of the speed measuring box 302 close to the matching ring 104; the guide component is connected to the support platform 301; the matching component is connected to the mounting seat 105, the guide column 304 is slidably connected to the support platform 301 and is fixedly installed on one side of the speed measuring box 302; the two sides of the extrusion spring 305 are respectively connected to the speed measuring box 302 and the support platform 301, the support platform 301 is fixedly set on one side of the mounting seat 105, the speed measuring box 302 is installed on one side of the support platform 301 through the guide columns 304 provided on both sides, and the extrusion spring 305 is set on both sides of the speed measuring box 302 to connect the bosses and the top of the support platform 301 The speed measuring wheel 303 of the speed measuring box 302 contacts the outer ring of the matching ring 104, and the contact position between the speed measuring wheel 303 and the matching ring 104 is located outside the outer ring of the matching ring 104, so as to avoid the speed measuring wheel 303 being affected by the stuck groove 108 on the inner side of the matching ring 104 when the speed measuring wheel 303 is matched with the matching ring 104. In normal operation, the speed measuring box 302 will drive the measuring wheel 303 to rotate under the action of the guide column 304 and the extrusion spring 305. The speed wheel 303 is in close contact with the outer ring of the mating ring 104. When the outer ring of the mating ring 104 rotates normally, the speed measuring wheel 303 will rotate along with the mating ring 104 due to the effect of friction. In this way, the speed measuring box 302 can calculate the approximate rotation speed of the mating ring 104 by measuring the rotation speed of the speed measuring wheel 303, so that in subsequent braking, the timing of locking the mating ring 104 can be selected through the preliminary calculation of the rotation speed of the mating ring 104.

[0043] Secondly, the expenditure frame 306 is fixedly connected to the mounting seat 105 and is located on one side of the mounting seat 105; the clamping frame 307 is connected to the expenditure frame 306 and is located on the side of the expenditure frame 306 close to the matching ring 104; the two sides of the ejection spring 308 are respectively connected to the clamping frame 307 and the expenditure frame 306; the rotating baffle 309 is rotatably connected to the expenditure frame 306 and is located on the side of the expenditure frame 306 close to the clamping frame 307; the output shaft of the rotating motor 310 is connected to the rotating baffle 309, and the rotating motor 310 is fixedly mounted on one side of the expenditure frame 306; the controller 311 is electrically connected to the speed measuring box 302 The mounting bracket 306 is connected to the mounting seat 105, and is electrically connected to the rotating motor 310, and is installed on one side of the speed measuring box 302. The dispensing frame 306 is fixedly arranged on the side of the mounting seat 105, and the clamping frame 307 is slidably arranged on the dispensing frame 306. The overall structure of the clamping frame 307 is similar to that of the clamping frame 106, except that the clamping frame 307 is provided with a clamping boss for cooperating with the clamping groove 108 on the inner side of the matching ring 104 on the side close to the matching ring 104, and the ejection spring 308 is installed between the inner wall of the clamping frame 307 and the outer wall of the dispensing frame 306, and the rotating baffle 309 is rotatably installed on the inner side of the clamping frame 307. The rotating baffle 309 is rotatably mounted on the inner side of the clamping frame 307. The output shaft of the motor 310 is fixed, the rotating motor 310 is connected to the controller 311 through a corresponding control circuit, and the controller 311 is connected to the speed measuring box 302 through a corresponding data transmission circuit. When the control box receives the rotation speed data of the mating ring 104 through the speed measuring box 302, the rotation speed data of the mating ring 104 can be analyzed. Once the rotation speed of the mating ring 104 is reduced to a preset range, the controller 311 controls the rotating motor 310 to drive the rotating baffle 309 to rotate. When the rotating baffle 309 rotates, the dispensing frame 306 moves toward the mating ring 104 under the action of the ejection spring 308. After the locking boss at the end of the deployment frame 306 is aligned with the locking groove 108 on the surface of the matching ring 104, the deployment frame 306 will directly insert the locking boss into the locking groove 108 under the action of the ejection spring 308, thereby locking the matching ring 104 and the entire roller body 102, so that the entire braking stroke can be shortened to the greatest extent. Moreover, since the locking timing is determined by the speed measurement data of the speed measurement box 302, the force exerted on the locking boss and the locking groove 108 due to the rotation of the matching ring 104 and the roller body 102 itself when the locking frame 307 is matched with the matching ring 104 can be estimated in advance.

[0044] When using a direct-driven permanent magnet electric roller device of the present embodiment, the guide column 304 can cooperate with the extrusion spring 305 to make the speed measuring wheel 303 on the side of the speed measuring box 302 contact with the outer ring of the matching ring 104, and then the rotation speed of the matching ring 104 can be analyzed and judged by the rotation of the speed measuring wheel 303 and the speed measuring box 302. When the speed of the matching ring 104 and the roller body 102 is slowed down due to the clamping brake of the rubber wipers 111 on both sides, the speed measuring box 302 can analyze and judge the matching ring 104 and the roller body 102 through the change of the rotation speed of the speed measuring wheel 303. The rotation speed is monitored. Once the rotation speed of the drum body 102 and the matching ring 104 is reduced to a preset range, the rotating motor 310 can drive the rotating baffle 309 to rotate, and then the clamping frame 307 cooperates with the locking groove 108 provided on the surface of the matching ring 104 under the action of the ejection spring 308, thereby locking the matching ring 104 and the drum body 102, which greatly shortens the entire braking stroke and reduces the consumption of the rubber wiper 111. At the same time, it can also effectively prevent the permanent magnet electric drum body 102 from rotating arbitrarily and causing braking failure, greatly enhancing the practicality of the entire device.
