Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying for electric vehicle frame processing, and specifically to a suspension conveying device for electric vehicle frame processing. Background Art

[0002] During the processing of electric vehicle frames, a suspension conveying device can be used for the aerial distribution of workpieces. With a reasonable design, it can organically combine relevant nodes such as warehouses and assembly lines, and can streamline the workshop logistics to the greatest extent, generating greater benefits. The suspension conveying device transports between multiple process equipment, and during the transportation process, the release position and stability of the workpiece are crucial.

[0003] For example, the patent with the publication number CN205132353U discloses a transport rack for a suspension conveying device, which includes a frame plate module and hanging plate modules respectively arranged at both ends of the frame plate module. Hanging columns are arranged on the hanging plate modules; the frame plate module includes two correspondingly arranged frame plates and a first frame plate fixing member for setting the space for arranging the two frame plates. A second frame plate fixing member is arranged at the left end of the frame plate module, and a first rotating shaft sleeve is arranged on the second frame plate fixing member. A limiting wheel module is arranged on the first rotating shaft sleeve. The limiting wheel module includes a first rotating wheel body fixedly arranged on the first rotating shaft sleeve, a limiting wheel frame fixedly arranged on the first rotating wheel body, and a limiting wheel body arranged on the limiting wheel frame. An auxiliary limiting platform is arranged at the right end of the frame plate module; by arranging the limiting wheel module and the auxiliary limiting platform, the transport racks can be stopped when they come into contact with each other through the limiting wheel module and the auxiliary limiting platform.

[0004] For example, the patent with the publication number CN205098915U discloses a driving device and a driving track system for a suspension conveying device, which includes a driving wheel module, a walking wheel module fixedly connected to the driving wheel module through a connecting member, and a hoisting plate arranged at the lower end of the walking wheel module; the driving wheel module includes a first mounting plate fixedly connected to the connecting member, a first driving wheel mounting plate obliquely arranged on the left side of the first mounting plate, and a second driving wheel mounting plate arranged on the right side of the first mounting plate corresponding to the first driving wheel mounting plate. Two groups of corresponding driving wheels are respectively arranged on the first driving wheel mounting plate and the second driving wheel mounting plate. The driving wheel includes a driving wheel mounting frame and a driving wheel body arranged on the driving wheel mounting frame; by arranging the driving wheel module, when the driving wheel body on the driving wheel module rotates on the driving shaft, it further drives the operation of the driving device through its friction rotation with the driving shaft, and the transmission mode is more concise.

[0005] As disclosed in the patent with publication number CN108147039B, a suspension conveying device is disclosed. The suspension conveying device includes: a plurality of conveying frames arranged on a suspension conveying track; the conveying frame includes: a driving wheel set, a walking trolley connecting the driving wheel set, a slider arranged at the front end of the walking trolley, and a flip-type limiting member arranged at the rear end of the walking trolley; the flip-type limiting member is hinged on the walking trolley, and the flip-type limiting member is connected to the driving wheel set through a brake wire; two adjacent conveying frames are respectively a front conveying frame and a rear conveying frame. When two adjacent conveying frames meet, the slider of the rear conveying frame slides on the flip-type limiting member of the front conveying frame, and the flip-type limiting member of the rear conveying frame rotates, driving the driving wheel set of the rear conveying frame away from the suspension conveying track, realizing the stop of the sliding of the rear conveying frame; avoiding the problem of concentrated force on the rotating shaft of the roller, thus increasing the service life and ensuring normal production; the suspended conveying device relies on a stable suspension system to maintain the balance of the workpiece during transportation. If the braking system is unstable, especially during rapid braking, it may cause the workpiece to shift or slip during the release process, thus affecting the accuracy and efficiency of conveying. Such unstable braking actions may cause the workpiece to be unable to be accurately positioned during transportation, increasing the operation risk. In addition, if the braking is too fast and the buffer force is insufficient, it may cause problems such as braking jitter and deviation in the running direction, and the suspension system will also bear a certain impact force, posing a threat to the safety of the entire conveying device.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original suspension conveying device for electric vehicle frame processing. Summary of the Invention

[0008] To achieve the above object, the present invention provides the following technical solution: A suspended conveying device for the processing of an electric vehicle frame, including an upper sliding track fixedly installed on the top of an electric vehicle frame production workshop. A lower sliding track is fixedly installed at the lower end of the upper sliding track. A driving wheel is rotatably installed in the lower sliding track. The driving wheel is rotatably installed on a suspension bracket. The suspension bracket is movably arranged outside the lower sliding track. A support frame for assisting the rotation of the driving wheel is fixedly installed at the middle position of the lower sliding track; A hoisting frame is fixedly connected to the support frame. A rotating belt is rotatably sleeved on the hoisting frame. Two suspension belts are fixedly connected to the rotating belt. A thickened pad for padding and supporting under the electric vehicle frame is fixed between the two suspension belts; A braking mechanism for controlling the buffered and stable stop of the driving wheel is arranged on the suspension bracket. And the operation of the braking mechanism can tighten and limit the electric vehicle frame on the thickened pad, thereby reducing the influence of braking inertia.

[0009] Preferably, the braking mechanism includes a lifting bracket longitudinally slidably connected to the suspension bracket. A guiding disc seat is fixedly installed on the lifting bracket; A guiding chute is formed on the guiding disc seat. A sliding disc is slidably installed in the guiding chute. A braking wheel rotatably installed on the upper sliding track is rotatably connected to the sliding disc.

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

[0011] Preferably, a cylindrical rod is fixedly connected to the guiding disc seat. A speed-limiting spring is sleeved outside the cylindrical rod; The sliding disc is slidably sleeved outside the cylindrical rod. And the speed-limiting spring is elastically connected between the sliding disc and the guiding disc seat.

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

[0013] Preferably, a hollow seat is fixedly installed at the lower side of the thickened pad. And a stretchable belt is fixedly connected to the middle of one side of the upper end of the thickened pad. The stretchable belt passes through and is slidably connected in the hollow seat.

[0014] Preferably, a pulling disc is fixedly installed at the movable end of the stretchable belt. A pulling rope for controlling the stretching and tightening of the stretchable belt is connected to the pulling disc; A directional sliding ring is fixedly installed on the lifting bracket. The pulling rope passes through and is slidably connected in the directional sliding ring; A power mechanism for controlling the movement of the pulling rope is arranged on the guiding disc seat.

[0015] Preferably, the power mechanism includes a mounting seat fixedly installed on the sliding disc. A winding disc is rotatably installed on the mounting seat. The pulling rope is wound around the winding disc.

[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: (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.

[0019] (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.

[0020] (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.

[0021] (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.

[0022] (5) A power mechanism for controlling the movement of the pulling rope is provided on the guide disk 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 pulling rope, initially realizing the tightening of the elastic band. When the brake wheel contacts the brake channel and decelerates, the sliding disk moves downward and drives 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 disk. The winding disk rotates to wind the pulling rope, further tightening the elastic band to keep the electric vehicle frame workpiece stably limited on the suspension conveying device.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1-9 , the present invention provides the following technical solutions: A suspension conveying device for the processing of an electric vehicle frame, including an upper sliding track 1 fixedly installed on the top of an electric vehicle frame production workshop. The lower end of the upper sliding track 1 is fixedly installed with a lower sliding track 2. A driving wheel 3 is rotatably installed in the lower sliding track 2. The driving wheel 3 is rotatably installed on a suspension bracket 4. The suspension bracket 4 is movably arranged outside the lower sliding track 2. A support frame 5 for assisting the rotation of the driving wheel 3 is fixedly installed at 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. A thickened pad 9 for padding and supporting under the electric vehicle frame is fixed between the two suspension belts 8; A braking mechanism for controlling the buffered and stable stop of the driving wheel 3 is arranged on the suspension bracket 4, and when the braking mechanism operates, it can tighten and limit the electric vehicle frame on the thickened pad 9 so as to reduce the influence of braking inertia.

[0039] The braking mechanism includes a lifting bracket 11 longitudinally slidably connected to the suspension bracket 4. A guide disc seat 12 is fixedly installed on the lifting bracket 11; A guide chute 13 is opened on the guide disc seat 12. A sliding disc 14 is slidably installed in the guide chute 13. A brake wheel 15 rotatably connected to the sliding disc 14 is rotatably installed on the upper sliding track 1.

[0040] 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 channel 16 close to the brake wheel 15 is inclined, and the brake channel 16 is inclined downward along the rolling direction of the brake wheel 15.

[0041] A cylindrical rod 141 is fixedly connected to the guiding disc base 12, and a speed-limiting spring 142 is sleeved outside the cylindrical rod 141; the sliding disc 14 is slidably sleeved outside the cylindrical rod 141, and the speed-limiting spring 142 is elastically connected between the sliding disc 14 and the guiding disc base 12.

[0042] An electric telescopic rod 111 is fixedly installed on the support frame 5, the output end of the electric telescopic rod 111 is fixedly connected to a driving bracket 112, and the driving bracket 112 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.

[0043] The installation routes of the upper sliding track 1 and the lower sliding track 2 are between multiple electric vehicle frame workpiece processing devices. The electric vehicle frame workpiece is placed on the thickened pad 9. For longer workpieces, they can be placed on two adjacent groups of thickened pads 9. The suspension belt 8 is stretched to protect the outside of the workpiece, and the elastic band 92 is elastically tightened on the surface of the workpiece. The driver 10 is operated to control the driving wheel 3 to roll in the lower sliding track 2. At this time, the upper brake wheel 15 rolls in contact with 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.

[0044] When the electric vehicle frame workpiece is transported to the side of a certain process equipment and the driver 10 stops operating, at this time, the driving wheel 3 will continue to roll a certain distance due to the rotational inertia. In order to reduce the influence of inertia during 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 guiding disc base 12 and the brake wheel 15 to move upward, so that the brake wheel 15 moves into contact with the upper brake channel 16. The brake wheel 15 contacts the inclined surface of the brake channel 16. During the remaining distance of the continuous rotation of the driving wheel 3, the brake wheel 15 rolls on the inclined surface of the brake channel 16. The brake wheel 15 is subjected to the extrusion of the inclined surface, and the rolling friction force gradually increases, so that the resistance of the overall movement of the conveying device gradually increases, and the brake wheel 15 and the driving wheel 3 can stop stably.

[0045] When the brake wheel 15 contacts the inclined surface of the brake channel 16, the brake wheel 15 moves downward under the extrusion of the inclined surface. The brake wheel 15 controls the sliding disc 14 to engage and slide downward in the guiding chute 13. The sliding disc 14 is also sleeved outside 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 decelerate and brake, but also buffer the vibration force generated during the braking process, maintaining the stability of the overall suspension conveying device during the braking process, so that the electric vehicle frame workpiece can be stably transported and stopped.

[0046] Embodiment 2: Please refer toFigures 1-13 , on the basis of the first embodiment, a power mechanism is further disclosed, and its specific structure is as follows: A hollow seat 91 is fixedly installed below the side of the thickening pad 9, and an elastic band 92 is fixedly connected to the center of one side of the upper end of the thickening pad 9. The elastic band 92 is slidably connected through the hollow seat 91.

[0047] A pulling disc 93 is fixedly installed at the movable end of the elastic band 92, and a pulling rope 94 for controlling the stretching and tightening of the elastic band 92 is connected to the pulling disc 93; A directional sliding ring 95 is fixedly installed on the lifting bracket 11, and the pulling rope 94 is slidably connected through the directional sliding ring 95; A power mechanism for controlling the movement of the pulling rope 94 is provided on the guide disc seat 12.

[0048] The power mechanism includes a mounting seat 941 fixedly installed on the sliding disc 14. A winding disc 943 is rotatably installed on the mounting seat 941, and the pulling rope 94 is wound around the winding disc 943.

[0049] A small gear 942 is rotatably installed at one end of the mounting seat 941 away from the winding disc 943. The small gear 942 is coaxially connected to the winding disc 943; A large gear 944 meshing with the small gear 942 is also rotatably installed on the mounting seat 941. A rack 945 is longitudinally fixedly installed on the guide disc seat 12, and the rack 945 is meshed with the large gear 944.

[0050] 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 disc 943 to move upward. The upward movement of the winding disc 943 generates a pulling effect on the pulling rope 94, and the pulling rope 94 transmits the pulling force to the elastic band 92, so that the elastic band 92 is initially elastically tightened on the surface of the electric vehicle frame workpiece.

[0051] When the brake wheel 15 contacts the brake channel 16 and pushes the sliding disc 14 to move downward, at this time, the large gear 944 on the mounting seat 941 meshes and moves downward beside the rack 945. Under the meshing transmission, the large gear 944 rotates. The other end of the large gear 944 is meshed with the small gear 942. Under the meshing transmission, the small gear 942 can be controlled to rotate at an accelerated speed. The small gear 942 drives the winding disc 943 to rotate synchronously. The rotation of the winding disc 943 can wind the pulling rope 94, so that the pulling rope 94 further generates a pulling force. The winding of the pulling rope 94 can elastically stretch the elastic band 92, so that the elastic band 92 is elastically tightened and protected on the surface of the electric vehicle frame workpiece, avoiding the situation that the workpiece on the electric vehicle slides on the suspension conveying device due to inertia during the braking process.

[0052] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
