Description

Technical Field

[0001] The utility model relates to the field of steel cord production, and in particular to a multi-station high-frequency conveying hoist. Background Art

[0002] The production of steel cord usually requires the use of a production line that occupies a large area. In order to improve the practical efficiency of the space, the production line is usually set up at the upper and lower ends, and the materials are transferred by a hoist in the middle.

[0003] At present, steel cord hoists usually use motors to lift and transport frames through chains. Only single materials can be transported on the transport frames. Only a single I-shaped wheel wrapped with steel cord materials can be transported from bottom to top at a time. With the improvement of production efficiency and the optimization of processes, the production line needs to be able to accept multiple materials for distribution at the same time. Each time a single material needs to be lifted up and down repeatedly by the hoist, which makes the actual work efficiency low. If the current hoist enters multiple I-shaped wheel materials at one time, collision damage will occur between the I-shaped wheels, or it will be difficult to separate them at subsequent workstations.

[0004] Therefore, a conveyor elevator capable of multi-station transportation and high-frequency transportation is needed to improve production efficiency. Summary of the invention

[0005] The main purpose of the utility model is to provide a multi-station high-frequency conveying elevator, which can transport multiple objects on the transfer device at the same time to improve the conveying efficiency of the conveyor, and at the same time drive the conveying rollers through different drive motors A to prevent collision and damage between materials.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A multi-station high-frequency conveying elevator, comprising:

[0008] A frame, wherein a driving device is arranged on the upper part of the frame, the driving device is drivingly connected to the transport frame, and the transport frame moves up and down along the frame under the action of the driving device;

[0010] Further, a plurality of photoelectric sensors are fixed on one side of the transfer plate. The photoelectric sensors correspond to the driving motor A one by one and are electrically connected to a controller to control the operation of the driving motor A.

[0011] Further, the ends of the two transfer plates are connected by a connecting plate, and the blocking rod is eccentrically rotatably connected to the center of the connecting plate;

[0012] During lifting, the blocking rod is in a vertical state and its upper end protrudes above the upper surface of the transfer roller;

[0013] When rising or falling in place, the blocking rod is squeezed by the offset baffle installed on the frame, causing the blocking rod to tilt and its upper end to descend below the upper surface of the transfer roller.

[0014] Further, the offset baffle includes a bottom plate and a blocking edge. The blocking edge is arranged in a V shape, and one side edge is fixedly connected to the bottom plate in the vertical direction. A plurality of waist-shaped holes are arranged on the bottom plate.

[0015] Further, rollers are respectively fixedly connected to both ends of the blocking rod.

[0016] Further, the driving device includes a driving motor B, a chain B, and a counterweight. The driving motor B is fixedly connected to the upper end of the frame. A sprocket cooperating with the chain B is fixedly connected to the output end of the driving motor B. One end of the chain B is fixedly connected to one end of the transport frame and the other end is fixedly connected to the counterweight.

[0017] Further, a guiding strip A is arranged on the frame in the vertical direction. A guiding pulley cooperating with the guiding strip A is arranged on the transport frame. A guiding strip B is arranged on the frame in the vertical direction. A guiding block cooperating with the guiding strip B is arranged on the side of the counterweight.

[0018] Further, hydraulic buffers are arranged at the lower end of the frame. There are two hydraulic buffers, which are respectively arranged at the diagonal corners below the transport frame.

[0019] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0020] By arranging a plurality of driving motors A on the transfer device and driving different sections of the driving rollers through the driving motors A, the materials entering the transfer device can be conveyed in multiple segments, avoiding collisions between the materials, transporting multiple materials at a time, and realizing multi-station high-frequency transportation.

[0021] By arranging photoelectric sensors, the movement of each driving motor A is controlled, avoiding collisions of materials.

[0022] By arranging the blocking rod, it is avoided that the materials fall off the transfer device during the rising process.

[0023] By setting a displacement baffle, when the transportation arrives in place, through the mutual cooperation of the retaining rod and the displacement baffle, the material can be transported onto or off the transfer device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] As Figures 1 to 8 shown, a multi-station high-frequency conveying elevator includes

[0035] A frame 10, wherein a driving device 101 is disposed on the upper portion of the frame 10, wherein the driving device 101 is drivingly connected to a transport frame 102, and the transport frame 102 moves up and down along the frame 10 under the action of the driving device 101;

[0036] The transfer device 20 is fixedly connected to the transport frame 102, and the transfer device 20 includes two parallel conveying plates 201, a plurality of conveying rollers 202, and a plurality of driving motors A203. The conveying plates 201 are fixedly connected to the transport frame 102, and the conveying rollers 202 are arranged between the conveying plates 201. The driving motors A203 are fixedly connected below the conveying plates 201 at equal intervals along the length direction, and each of the driving motors A203 is connected to a plurality of conveying rollers 202 of the same number through a chain drive.

[0037] Specifically, by arranging multiple driving motors A203 on the transfer device 20 and respectively driving the same number of conveying rollers 202 through chains, the spatial position occupied by each steel curtain I-shaped wheel to be transferred can be made the same, and multiple I-shaped wheels to be transferred can be transported at the same time to achieve high-frequency transportation. A protective net is fixed to the outside of the frame 10, and conventional safety measures such as setting an emergency stop switch are conventional means and are not described in detail.

[0038] Furthermore, a plurality of photoelectric sensors 2011 are fixed to one side of the transmission plate 201 . The photoelectric sensors 2011 correspond to the driving motors A203 one by one and are electrically connected to a controller to control the operation of the driving motors A203 .

[0039] Specifically, a photoelectric sensor 2011 is set to monitor whether the I-shaped wheel to be transferred is in place, so as to control the operation of the corresponding drive motor A203. The specific control method is a conventional technical means, which will not be described in detail here, to avoid collision between adjacent materials to be transferred.

[0040] Furthermore, the materials in the process of transportation are limited, and the limit is automatically opened after the movement is in place. The ends of the two conveying plates 201 are connected by a connecting plate 204, and the blocking rod 205 is eccentrically rotated and connected to the center of the connecting plate 204;

[0041] When lifting, the blocking rod 205 is in a vertical state and the upper end thereof protrudes from the upper surface of the conveying roller 202;

[0042] When rising or falling in place, the shift lever 205 is squeezed by the offset baffle 103 installed on the frame 10, causing the shift lever 205 to tilt and the upper end to drop below the upper surface of the conveying roller 202. The offset baffle 103 includes a bottom plate 1031 and a retaining edge 1032. The retaining edge 1032 is arranged in a V shape, and one side edge is fixedly connected to the bottom plate 1031 in the vertical direction. A plurality of kidney-shaped holes 10311 are provided on the bottom plate 1031. Roller 2051 is fixedly connected to both ends of the shift lever 205. With such a setting, during the lifting process, due to the self-gravity of the shift lever 205, it is in a vertical state, and the upper end limits the materials on the conveying roller 202 to prevent them from falling. When transported upward in place, the roller 2051 at the upper end of the shift lever 205 contacts the inner wall of the inclined retaining edge 1032, causing the upper end of the baffle 205 to drop below the lower surface of the conveying roller 202. When transported downward in place, the roller 2051 at the lower end of the shift lever 205 disengages from the outer wall of the inclined retaining edge 1032, causing the shift lever 205 to be inclined and its upper end to drop below the lower surface of the conveying roller 202.

[0043] Further, the driving device 101 includes a driving motor B1011, a chain B1012, and a counterweight 1013. The driving motor B1011 is fixedly connected to the upper end of the frame 10. A sprocket engaged with the chain B1012 is fixedly connected to the output end of the driving motor B1011. One end of the chain B1012 is fixedly connected to one end of the transport frame 102 and the other end is fixedly connected to the counterweight 1013. At the same time, in order to ensure stable operation, four chains B1012 are provided, which are respectively fixed to the four corners of the transport frame 102. Such a setting can ensure the stable operation of the transport frame.

[0044] Further, in order to ensure the stability of the transport frame 201 and the counterweight 1013 during up and down movement, guide bar A103 is provided on the frame 10 along the vertical direction. Guide pulley 1021 engaged with the guide bar A103 is provided on the transport frame 201. Guide bar B105 is provided on the frame 10 along the vertical direction. Two guide bars A104 are provided, which are respectively arranged at the centers of both sides of the transport frame 201. The guide pulleys 1021 are arranged in pairs and there are four groups. Guide block 10131 engaged with the guide bar B105 is provided on the side of the counterweight 1013. Two guide bars B105 are provided, which are respectively arranged on both sides of the counterweight 1013. Four guide blocks 10131 are provided, which are respectively arranged at the four corners of the counterweight 1013.

[0045] Further, in order to ensure that the transfer device 20 can operate stably when carrying multiple materials at the lower part, a hydraulic buffer 106 is provided at the lower end of the frame 10. Two hydraulic buffers 106 are provided, which are respectively arranged at the diagonal corners below the transport frame 102. By providing the hydraulic buffer 106, the impact when the transport frame falls can be effectively alleviated. At the same time, when carrying multiple workpieces to be transferred, support can be effectively provided.
