Description

Technical Field

[0002] The transport stacking device is a special equipment used for handling and stacking of goods in warehouses, workshops and other places. It can realize the automatic handling, stacking and storage of goods. There are many types of transport stacking devices, which can be roughly divided into pallet stacking and shelf stacking. The application of transport stacking devices can greatly improve the utilization rate of warehouses and the turnover rate of goods, reduce the labor intensity of workers, and improve work efficiency. The transport stacking device can be used in many fields. For example, when transferring spherical mill cast pipes in workshops, corresponding shelf-type transport stacking devices will be used.

[0003] At present, when the existing transport and stacking devices stack the anti-corrosion ductile iron pipes, due to the large size of the anti-corrosion ductile iron pipes, lifting equipment is generally used to stack them. However, when the anti-corrosion ductile iron pipes are stacked together, it is easy for two anti-corrosion ductile iron pipes to collide, which will knock off the anti-corrosion coating on the surface of the anti-corrosion ductile iron pipes.

DETAILED DESCRIPTION

The side surfaces of the two baffles 2124 that are away from each other are respectively in contact with the side surfaces of the two limit plates 2118 that are close to each other. By setting up a sub-packaging unit 21, the sub-packaging unit 21 can be used to pack the anti-corrosion ductile iron pipes that need to be stacked and transported in different areas, thereby ensuring that the anti-corrosion ductile iron pipes will not be damaged by bumps during the stacking process.

[0024] See also Figure 7One end of the first rotating shaft 2128 is fixedly connected to the first winding drum 2115, the front side of the lifting frame 2113 is fixedly connected to the fixed box 2106, the inner wall of the fixed box 2106 is fixedly connected to the fixed plate 2130, the right side of the fixed plate 2130 is fixedly connected to the first return spring 2131, the right end of the first return spring 2131 is fixedly connected to the first circular plate 2132, the right side of the first circular plate 2132 is fixedly connected to the first transmission rope 2133, the outer surface of the first transmission rope 2133 is fixedly connected to the outer surface of the first winding drum 2115, and the first return spring 2131 is provided to convert the power of the first rotating shaft 2128 during rotation into elastic potential energy and store it. When the first rotating shaft 2128 and the flip plate 2105 are no longer subjected to power, they will be reset under the action of the first return spring 2131, the first transmission rope 2133 and the first circular plate 2132.

[0025] See also Figure 2 The bottom surface of each self-locking motor 2102 is fixedly connected to a support plate 2107, and the side surfaces of the two support plates 2107 close to each other are respectively fixedly connected to the front and back sides of the lifting frame 2113. By providing the support plates 2107, the support plates 2107 can provide a stable supporting force for the self-locking motor 2102.

[0026] See also Figure 3 Two fixed seats 2119 and two second winding drums 2116 are respectively arranged above the lifting frame 2113. The interior of each second winding drum 2116 is clamped on the outer surface of the fourth rotating shaft 2117.

The front side of each second circular plate 2121 is fixedly connected with a second transmission rope 2122. The outer surface of each second transmission rope 2122 is fixedly connected to the outer surface of the second winding drum 2116. By setting the second winding drum 2116 and utilizing the clamping relationship between the second winding drum 2116 and the fourth rotating shaft 2117, the power generated when the limiting plate 2118 and the fourth rotating shaft 2117 rotate can be transmitted to the second winding drum 2116, thereby driving the second transmission rope 2122 to contract and the second reset spring 2120 to stretch. When the limiting plate 2118 is not subjected to the thrust when the third gear 2112 rotates, it will be reset under the action of the second reset spring 2120.

[0027] See also Fig. 9Two T-shaped slots 2135 are provided on the upper surface of the lifting frame 2113, and a T-shaped slider 2127 is slidably connected inside each T-shaped slot 2135. The sides of the two T-shaped sliders 2127 that are close to each other are fixedly connected to the sides of the two lifting plates 2134 that are away from each other. The inner wall of each extrusion block 2137 is rotatably connected to a roller 2129. By providing the T-shaped slot 2135 and the T-shaped slider 2127, and utilizing the sliding connection relationship between the T-shaped slider 2127 and the T-shaped slot 2135, the position of the lifting plate 2134 can be limited, so that the lifting plate 2134 can only move up and down.

[0028] The specific implementation of this embodiment is as follows: when the device is needed, the anti-corrosion ductile iron pipe to be stacked and transported needs to be lifted with the help of a lifting device, and then placed on the surface of the flip plate 2105, and there is a certain depression on the surface of the flip plate 2105, so the anti-corrosion ductile iron pipe can be effectively lifted, and then the self-locking motor 2102 is controlled to run. When the self-locking motor 2102 is running, power will be transmitted to the reciprocating screw 2126 fixed at the output end, thereby driving the reciprocating screw 2126 to rotate. It should be understood here that when the reciprocating screw 2126 rotates, the groove on its surface will also rotate accordingly, and the reciprocating block 2138 inside the groove can move back and forth under the action of the extrusion of the inner wall of the reciprocating screw 2126, and it is necessary It should be understood that in the present application, when the reciprocating screw 2126 rotates one circle, the reciprocating block 2138 just moves from one end of the reciprocating screw 2126 to the other end. Therefore, when the reciprocating block 2138 is moving, it will push the reciprocating plate 2136 and the extrusion block 2137 to move, and the extrusion block 2137 will first push the lifting plate 2134 on the right to move upward, and the upward movement of the lifting plate 2134 will push the flip plate 2105 to tilt, so the anti-corrosion ball mill cast pipe placed on the surface of the flip plate 2105 will roll to the left side space of the first layer of the transport rack 2101. As the reciprocating screw 2126 continues to rotate, the extrusion block 2137 will stop squeezing the lifting plate 2134, so the lifting plate 2134 will reset under the action of gravity, and the self-locking motor 2 102 will stop running and wait for the lifting equipment to lift the next anti-corrosion ball mill cast pipe. The self-locking motor 2102 will run again. The running of the self-locking motor 2102 will also push the reciprocating plate 2136 and the extrusion block 2137 to move, thereby pushing the lifting plate 2134 on the left side to move upward, so that the anti-corrosion ball mill cast pipe placed on the surface of the flip plate 2105 rolls to the other side of the first layer. At this time, the self-locking motor 2102 only drives the reciprocating screw 2126 to rotate half a circle. Therefore, the reciprocating screw 2126 transmits power to the third shaft 2104 through the transmission gear belt group 2103, and the force can only make the third shaft 2104 and the first gear 2108 rotate half a circle. It should be understood here that the transmission gear belt group 2103 is It is composed of two transmission gears and a toothed belt. Therefore, the third rotating shaft 2104 and the reciprocating screw 2126 are both fixed on the center of the transmission gear in the transmission gear belt group 2103. As a result, the teeth on the surface of the first gear 2108 will just contact the teeth on the surface of the second gear 2109. When the anti-corrosion spherical mill cast pipes of the first layer of the transport rack 2101 are placed, the self-locking motor 2102 is controlled to rotate continuously. The second gear 2109 will rotate under the continuous rotation of the self-locking motor 2102. The teeth on the surface of the second gear 2109 are used to drive the third rotating shaft 2104 to rotate, thereby driving the third gear 2112 fixed on the surface of the third rotating shaft 2104 to rotate. The meshing relationship between the third gear 2112 and the tooth plate 2114 is used.The lifting frame 2113 can be pushed to move upward, but when the first gear 2108 rotates half a circle again, the teeth on its surface will no longer mesh with the second gear 2109, so the lifting frame 2113 will stop moving upward. During the period when the lifting frame 2113 stops moving upward, the third gear 2112 is no longer powered by the self-locking motor 2102, but will be limited by the baffle 2124. Because the baffle 2124 can be freely extended and retracted under the action of the telescopic rod 2125, when the baffle 2124 is on one side of the limit plate 2118, the limit plate 2118 will not be able to move upward. The normal baffle 2124 rotates on the opposite side, so when the third gear 2112 stops rotating, the third gear 2112 cannot rotate in the opposite direction under the action of the baffle 2124 and the limit plate 2118, so the third gear 2112 will be locked to prevent the third gear 2112 from moving downward due to gravity when it is not powered by the self-locking motor 2102. In this way, the anti-corrosion ball mill cast pipes can be stacked on the transport rack 2101 from bottom to top, and the contact position between the transport rack 2101 and the anti-corrosion ball mill cast pipes is covered with a layer of rubber to prevent bumping.

Through the mutual cooperation of the fastening unit 22 and the packaging unit 21, it can be effectively ensured that the anti-corrosion ductile iron pipe will not collide and lose the corrosion-resistant coating during stacking and transportation.

By providing the roller 2212, the friction between the extrusion plate 2201 and the first force-bearing plate 2202 can be reduced when the extrusion plate 2201 moves downward.

[0032] See also Figure 2 Two card slots 2210 are provided on the upper surface of the lifting frame 2113, and a card block 2209 is clamped inside each card slot 2210. The top of each card block 2209 is fixedly connected to the bottom surface of the lifting block 2207. By clamping the card block 2209 inside the card slot 2210, the lifting block 2207 can be removed and replaced.

[0033] The specific implementation of this embodiment is as follows: when the two anti-corrosion ductile iron pipes at the bottom of the transport frame 2101 are installed, the lifting frame 2113 will move upward to install the anti-corrosion ductile iron pipes of the second layer. When the anti-corrosion ductile iron pipes of the second layer are installed in place, the anti-corrosion ductile iron pipes of the second layer will squeeze the second force plate 2205 to move downward, so that the power can be transmitted to the second rubber pad 2206 through the second transmission column 2216, and the anti-corrosion ductile iron pipes can be clamped by the second rubber pad 2206. When the three-layer transport rack 2101 is completed, the lifting frame 2113 needs to move upward a certain distance under the action of the self-locking motor 2102, and at this time, the lifting block 2207 and the top shaft 2208 will be pushed upward until the top shaft 2208 pushes the extrusion plate 2201 to rotate around the short axis 2211 as the center of the circle, and the other side of the extrusion plate 2201 is used to provide a downward thrust to the first force plate 2202, and the power can also be transmitted to the first rubber pad 2215 through the first transmission column 2213 , thereby the two top anti-corrosion ball mill cast tubes can be clamped and fixed, and it should be understood here that the self-locking motor 2102 can automatically lock the rotor when not in operation to prevent it from rotating freely, thereby keeping the position of the rotor unchanged, so that pressure can be continuously applied to the two top anti-corrosion ball mill cast tubes, and it is necessary to ensure that the teeth of the first gear 2108 and the teeth of the second gear 2109 are in a meshing state, and it can be known that the pressure on the two anti-corrosion ball mill cast tubes on each layer comes from the two anti-corrosion ball mill cast tubes on the upper layer, and the pressure on the two top anti-corrosion ball mill cast tubes comes from the upward thrust generated by the operation of the self-locking motor 2102, and the self-locking motor 2102 can be self-locking, thereby ensuring that the anti-corrosion ball mill cast tubes on the entire transport rack 2101 are subjected to a stable clamping force to prevent shaking during movement, and the first rubber pad 2215 and the second rubber pad 2206 will reset under the action of the first force spring 2214 and the second force spring 2204 respectively after stopping being subjected to pressure.

[0034] Example 3: Please refer to Figure 1 , Figure 2 and Fig.10 The present invention provides a technical solution: a transportation and stacking device for anti-corrosion ductile iron pipes. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The unloading mechanism 3 cooperates with the anti-collision mechanism 2, and the unloading mechanism 3 can easily disassemble the anti-corrosion ductile iron pipes.

[0035] As a further limitation of the unloading mechanism 3 of the present invention, the unloading mechanism 3 includes three groups of first push plates 301, each group of first push plates 301 has two first push plates 301, and the side of each group of first push plates 301 away from each other is fixedly connected to two third force springs 309, one end of each third force spring 309 is fixedly connected to the inner wall of the transport frame 2101, and the side of each group of first push plates 301 away from each other is fixedly connected to two first rectangular plates 308, and the inner wall of each group of first rectangular plates 308 is rotatably connected to the first rotating shaft 307, and two second rectangular plates 305 are arranged on the outer side of each first push plate 301, and the side of each group of second rectangular plates 305 away from each other is fixedly connected to the transport frame 2101. The inner wall of the frame 2101 and the inner wall of each group of second rectangular plates 305 are rotatably connected to the second rotating shaft 304, the outer surface of each second rotating shaft 304 and the outer surface of the first rotating shaft 307 are fixedly connected to the transmission plate 306, the outer surface of each second rotating shaft 304 is fixedly connected to the flip frame 303, and the upper surface of the lifting frame 2113 is fixedly connected to two second push plates 302. By setting up a feeding mechanism 3, the feeding mechanism 3 can be used to disassemble the stacked anti-corrosion ball mill cast pipes. By setting up a packaging unit 21, a fastening unit 22 and a feeding mechanism 3, the problem of the corrosion-resistant coating of the anti-corrosion ball mill cast pipes being knocked and falling off due to collision during the use of the device can be effectively avoided.

[0036] The specific implementation of this embodiment is as follows: when the anti-corrosion ball mill cast pipe needs to be removed, the telescopic rod 2125 can be controlled to drive the baffle 2124 to retract. At this time, the third gear 2112 will not be limited by the baffle 2124 and the limit plate 2118, but will be limited by the self-locking motor 2102, so that the third gear 2112 cannot rotate. Then the self-locking motor 2102 is controlled to rotate in the opposite direction, so that the third gear 2112 rotates in the opposite direction, thereby driving the lifting frame 2113 to move downward as a whole. After the first gear 2108 rotates half a circle, the teeth on its surface will no longer be aligned with the teeth of the second gear 2109. The teeth are meshed, so the third gear 2112 is not subject to any limiting force at this time. At this time, it is necessary to control the telescopic rod 2125 to push the baffle 2124 to reset and re-limit the third gear 2112. Therefore, it can be understood that every time the first gear 2108 rotates 180 degrees, the telescopic rod 2125 needs to extend or retract once. As the lifting frame 2113 continues to move downward, the second push plate 302 on the right side of the lifting frame 2113 will gradually enter the flip frame 303, and the bottom and upper surfaces of the second push plate 302 are both inclined, so that the flip frame 303 can be pushed around The second rotating shaft 304 rotates, and the rotation of the second rotating shaft 304 will drive the transmission plate 306 to rotate, so that the first push plate 301 can be pushed to move through the transmission plate 306, and the first push plate 301 will push the anti-corrosion ball mill cast pipe on the right side of the third layer to roll toward the flip plate 2105. At this time, the flip plate 2105 will be exactly in a position parallel to the third layer. When the anti-corrosion ball mill cast pipe rolls onto the surface of the flip plate 2105, the self-locking motor 2102 is stopped, and with the assistance of the lifting equipment, the anti-corrosion ball mill cast pipe on the surface of the flip plate 2105 is removed, and then the self-locking motor 2102 is controlled to run. The second push plate 302 on the left also applies a thrust to the anti-corrosion ductile iron pipe on the left to move it to the flip plate 2105, and the above operation can be repeated. It should be understood here that the inclined surface of the second push plate 302 on the left is higher than the inclined surface of the second push plate 302 on the right. Therefore, the movement of the anti-corrosion ductile iron pipes on the same layer will have a sequence to avoid conflicts, and when the anti-corrosion ductile iron pipes are installed from bottom to top, the second push plate 302 will first trigger the flip frame 303 before the anti-corrosion ductile iron pipes are installed, and when the first push plate 301 stops being subjected to the thrust, it will be reset under the action of the third force spring 309.
