[0004] For example, the patent with publication number CN205098915U discloses a drive device and a drive rail system for a suspended conveying device, including a drive wheel module, a walking wheel module fixedly connected to the drive wheel module through a connecting piece, and a lifting plate arranged at the lower end of the walking wheel module; the drive wheel module includes a first mounting plate fixedly connected to the connecting piece, a first drive wheel mounting plate obliquely arranged on the left side of the first mounting plate, and a second drive wheel mounting plate corresponding to the first drive wheel mounting plate arranged on the right side of the first mounting plate, and two corresponding groups of drive wheels are respectively arranged on the first drive wheel mounting plate and the second drive wheel mounting plate, and the drive wheel includes a drive wheel mounting frame and a drive wheel body arranged on the drive wheel mounting frame; by setting the drive wheel module, the drive wheel body on the drive wheel module further drives the drive device to operate through the friction rotation between the drive shaft and the drive shaft when the drive shaft rotates, and the transmission mode is simpler.

[0005] For example, the patent with publication number CN108147039B discloses a suspended conveying device, which includes: a plurality of conveying frames arranged on a suspended conveying track; the conveying frame includes: a driving wheel group, a walking trolley connected to the driving wheel group, a slider arranged at the front end of the walking trolley, and a flip limiter arranged at the rear end of the walking trolley; the flip limiter is hinged on the walking trolley, and the flip limiter is connected to the driving wheel group through a brake line; the two adjacent conveying frames are respectively the front conveying frame and the rear conveying frame, and when the two adjacent conveying frames meet, the slider of the rear conveying frame slides on the flip limiter of the front conveying frame, and the flip limiter of the rear conveying frame rotates, driving the driving wheel group of the rear conveying frame to separate The suspended conveyor track is opened to stop the sliding of the rear conveyor frame; the problem of concentrated force on the rotating shaft of the roller is avoided, thereby increasing the service life and ensuring normal production; the suspended conveyor device relies on a stable suspension system to maintain the balance of the workpiece during transportation.

[0009] Preferably, the brake mechanism includes a lifting bracket longitudinally slidably connected to the suspension bracket, and a guide disc seat is fixedly installed on the lifting bracket; a guide groove is provided on the guide disc seat, a sliding disc is slidably installed in the guide groove, and a brake wheel is rotatably connected to the sliding disc and rollingly installed in the upper sliding track.

[0010] Preferably, a plurality of brake channels are continuously fixed on the upper sliding track along the rolling direction of the brake wheel. The brake channels are arranged above the brake wheel, and the side of the brake channels close to the brake wheel is inclined. The brake channels are inclined downward along the rolling direction of the brake wheel.

[0011] Preferably, a cylindrical rod is fixedly connected to the guide disc seat, and a speed limiting spring is sleeved on the outside of the cylindrical rod; the sliding disc sliding sleeve is arranged on the outside of the cylindrical rod, and the speed limiting spring is elastically connected between the sliding disc and the guide disc seat.

[0012] Preferably, an electric telescopic rod is fixedly mounted on the support frame, an output end of the electric telescopic rod is fixedly connected to a driving bracket, and the driving bracket is fixedly connected to the lifting bracket; a driver for controlling the rotation of the driving wheel is fixedly mounted on the suspension bracket.

[0016] Preferably, a small gear is rotatably mounted on one end of the mounting seat away from the winding disk, and the small gear is coaxially connected to the winding disk; a large gear meshing with the small gear is also rotatably mounted on the mounting seat.

[0017] Preferably, a rack is longitudinally fixedly mounted on the guide disc seat, and the rack is meshed with the large gear.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The suspended conveying device for processing the electric frame limits the workpiece to be placed on the thickened pad, and elastically limits the electric frame workpiece by tightening the belt, and controls the driving wheel to roll the electric frame workpiece in the sliding track, so that the electric frame workpiece is directionally conveyed at different process equipment points in a suspended state.

[0020] (2) A brake mechanism for controlling the driving wheel to stop in a buffered and stable manner is provided on the suspension bracket. When braking, the lifting bracket is controlled to move upward, and the lifting bracket drives the brake wheel to move upward synchronously, so that the brake wheel contacts the brake channel above. The brake wheel rolls on the inclined surface of the brake channel, and the purpose of deceleration is achieved through the progressive friction force generated by contact with the inclined surface. The brake wheel is kept in a buffer process during the braking process, avoiding large vibration and inertia force generated by the brake wheel during instantaneous deceleration, thereby maintaining the stability of the overall suspension conveying device in conveying the electric frame workpiece.

[0021] (3) When the brake wheel contacts the inclined surface of the brake channel, the brake wheel is pushed in the opposite direction by the inclined surface, pushing the sliding plate to move downward along the guide groove. The sliding plate presses the speed limit spring downward, which serves the purpose of buffering the brake and maintaining the rolling stability of the brake wheel during the deceleration and braking process, further improving the braking stability effect.

[0022] (4) An elastic band is elastically connected above the thickened pad. Under normal conditions, the elastic band is elastically protected on the surface of the electric frame workpiece to maintain the stability of the electric frame workpiece during suspension transportation. When the electric frame workpiece is controlled to pause, the elastic band is stretched by the pull rope so that the elastic band is tightened and protected on the surface of the electric frame workpiece, thereby improving the stable placement of the electric frame workpiece on the suspended conveying device, avoiding the workpiece from being affected by the brake inertia and moving and falling off at the moment of pause, and maintaining the precise positioning of the workpiece during transportation.

[0023] (5) A power mechanism for controlling the movement of the pull rope is provided on the guide disc seat. When the lifting bracket moves upward to adjust the position of the brake wheel, the lifting bracket drives the mounting seat to move upward synchronously to stretch the pull rope, thereby initially tightening the elastic band. When the brake wheel contacts the brake channel to decelerate, the sliding disc moves downward to drive the mounting seat to move downward synchronously. At this time, the rack, large gear and small gear engage in transmission, which can control the rotation of the winding disc. The winding disc rotates to reel in the pull rope, thereby further tightening the elastic band, thereby keeping the electric frame workpiece stably confined on the suspended conveyor device.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-9 The present invention provides the following technical solutions: a suspended conveying device for processing an electric frame, comprising an upper sliding track 1 fixedly mounted on the top of an electric frame production workshop, a lower sliding track 2 fixedly mounted on the lower end of the upper sliding track 1, a driving wheel 3 rollingly mounted in the lower sliding track 2, the driving wheel 3 rotatably mounted on a suspension bracket 4, the suspension bracket 4 movably arranged on the outside of the lower sliding track 2, a support frame 5 for assisting the rotation of the driving wheel 3 fixedly mounted in the middle position of the lower sliding track 2; a hoisting frame 6 is fixedly connected to the support frame 5, a rotating belt 7 is rotatably sleeved on the hoisting frame 6, two suspension belts 8 are fixedly connected to the rotating belt 7, and a thickened pad 9 is fixed between the two suspension belts 8 and supported under the electric frame; a brake mechanism for controlling the buffered stable stop of the driving wheel 3 is provided on the suspension bracket 4, and the operation of the brake mechanism can tighten the electric frame limited on the thickened pad 9 to reduce the influence of braking inertia.

[0040] The brake mechanism includes a lifting bracket 11 longitudinally slidably connected to the suspension bracket 4, and a guide disc seat 12 is fixedly installed on the lifting bracket 11; a guide groove 13 is provided on the guide disc seat 12, and a sliding disc 14 is slidably installed in the guide groove 13, and a brake wheel 15 rollingly installed in the upper sliding track 1 is rotatably connected to the sliding disc 14.

[0041] A plurality of brake channels 16 are continuously fixed on the upper sliding track 1 along the rolling direction of the brake wheel 15. The brake channels 16 are arranged above the brake wheel 15, and the side of the brake channels 16 close to the brake wheel 15 is inclined. The brake channels 16 are inclined downward along the rolling direction of the brake wheel 15.

[0042] A cylindrical rod 141 is fixedly connected to the guide disc seat 12, and a speed limiting spring 142 is sleeved on the outside of the cylindrical rod 141; the sliding disc 14 is slidably sleeved on the outside of the cylindrical rod 141, and the speed limiting spring 142 is elastically connected between the sliding disc 14 and the guide disc seat 12.

[0043] An electric telescopic rod 111 is fixedly installed on the support frame 5, and the output end of the electric telescopic rod 111 is fixedly connected to a driving bracket 112, which is fixedly connected to the lifting bracket 11; a driver 10 for controlling the rotation of the driving wheel 3 is fixedly installed on the suspension bracket 4.

[0044] The installation route of the upper sliding track 1 and the lower sliding track 2 is between multiple electric frame workpiece processing equipment. The electric frame workpiece is placed on the thickened pad 9. For longer workpieces, it can be placed on two adjacent groups of thickened pads 9. The suspension belt 8 is stretched out to protect the outside of the workpiece, and the elastic belt 92 is elastically tightened on the surface of the workpiece. The operating driver 10 controls the driving wheel 3 to roll in the lower sliding track 2. At this time, the upper brake wheel 15 rolls against the inner bottom surface of the upper sliding track 1 to assist in suspension transportation. The rotation of multiple wheels can make the suspension transportation direction accurate and maintain the relative stability of the suspension transportation.

[0045] The electric frame workpiece is transported to a certain process equipment, and the driver 10 is stopped. At this time, the driving wheel 3 will continue to roll for a distance under the rotational inertia. In order to reduce the influence of inertia when stopping, the electric telescopic rod 111 is operated to control the driving bracket 112 to move upward. The driving bracket 112 drives the lifting bracket 11 to move upward synchronously. The lifting bracket 11 controls the guide disc seat 12 and the brake wheel 15 to move upward, so that the brake wheel 15 moves to contact the brake channel 16 above, and the brake wheel 15 contacts the inclined surface of the brake channel 16. In the distance at one end of the driving wheel 3 continuing to rotate, the brake wheel 15 is attached to the inclined surface of the brake channel 16 and rolls. The brake wheel 15 is squeezed by the inclined surface, and its rolling friction gradually increases, thereby gradually increasing the resistance to the overall movement of the conveying device, keeping the brake wheel 15 and the driving wheel 3 able to stop stably.

[0046] When the brake wheel 15 contacts the inclined surface of the brake channel 16, the brake wheel 15 moves downward under the squeezing action of the inclined surface, and the brake wheel 15 controls the slide plate 14 to engage in the guide slide groove 13 and slide downward. At the same time, the slide plate 14 is sleeved on the outside of the cylindrical rod 141 and moves downward. When it moves downward, it compresses the speed limiting spring 142. The elastic force can not only further increase the resistance of the brake wheel 15 to deceleration and braking, but also buffer the vibration force generated during the braking process, maintain the stability of the overall suspension conveying device during the braking process, and enable the electric frame workpiece to be stably conveyed and stopped.

[0047] Example 2: Please refer to Figures 1-13 On the basis of embodiment 1, a power mechanism is also disclosed, and its specific structure is as follows: a hollow seat 91 is fixedly installed on the lower side of the thickened pad 9, and an elastic band 92 is fixedly connected to the center of one side of the upper end of the thickened pad 9, and the elastic band 92 passes through and is slidably connected in the hollow seat 91.

[0048] A pull disc 93 is fixedly installed on the movable end of the elastic band 92, and a pull rope 94 for controlling the stretching and tightening of the elastic band 92 is connected to the pull disc 93; a directional slip ring 95 is fixedly installed on the lifting bracket 11, and the pull rope 94 passes through and is slidably connected to the directional slip ring 95; a power mechanism for controlling the movement of the pull rope 94 is provided on the guide disc seat 12.

[0049] The power mechanism includes a mounting base 941 fixedly mounted on the sliding plate 14 , a winding disk 943 is rotatably mounted on the mounting base 941 , and the pull rope 94 is wound around the winding disk 943 .

[0050] A small gear 942 is rotatably mounted on the end of the mounting seat 941 away from the winding reel 943, and the small gear 942 is coaxially connected to the winding reel 943. A large gear 944 is also rotatably mounted on the mounting seat 941 and meshes with the small gear 942. A rack 945 is fixedly mounted longitudinally on the guide plate seat 12, and the rack 945 meshes with the large gear 944.

[0051] When the electric telescopic rod 111 is operated to control the lifting bracket 11 to move upward, the lifting bracket 11 drives the mounting seat 941 and the winding disk 943 to move upward. The upward movement of the winding disk 943 produces a stretching effect on the pull rope 94, and the pull rope 94 transmits the stretching force to the elastic band 92, so that the elastic band 92 is initially elastically tightened on the surface of the electric frame workpiece.

[0052] When the brake wheel 15 contacts the brake channel 16 and pushes the slide plate 14 downward, the large gear 944 on the mounting seat 941 engages with the rack 945 and moves downward, and the large gear 944 rotates under the meshing transmission, and the other end of the large gear 944 is meshed and connected with the small gear 942. Under the meshing transmission, the small gear 942 can be controlled to accelerate the rotation, and the small gear 942 drives the winding disk 943 to rotate synchronously. The rotation of the winding disk 943 can rotate and wrap the pull rope 94, so that the pull rope 94 further generates a tensile force. The winding of the pull rope 94 can elastically stretch the elastic band 92, so that the elastic band 92 is elastically tightened to protect the surface of the electric frame workpiece, thereby avoiding the inertia effect during the braking process that causes the electric workshop workpiece to slip on the suspended conveyor device.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
