Description

Technical Field

[0001] This invention belongs to the field of hose hoisting technology, and in particular relates to an automatic hoisting equipment for a PTFE metal hose spraying production line. Background Technology

[0002] PTFE metal hoses are high-performance hoses that combine the properties of polytetrafluoroethylene (PTFE) and metal. They are widely used in industries such as chemical, pharmaceutical, food, and semiconductor, and are suitable for harsh environments such as high temperature, high pressure, and strong corrosion. In some special applications, PTFE metal hoses require coating treatment to improve their performance, including the following special applications:

[0003] (1) Stainless steel may still corrode in specific environments (such as high salt spray, acidic atmosphere, marine environment). The external anti-corrosion coating can isolate corrosive media such as chloride ions and acid rain, and is suitable for harsh environments such as chemical plants and offshore platforms.

[0004] (2) When the metal braided layer is directly exposed, it may wear due to mechanical friction (such as collision with pipes and equipment). Coating with wear-resistant materials (such as ceramic coating, polyurea) can extend the life of the hose in dynamic use. This is common in high-frequency friction scenarios such as mining machinery and conveying pipelines.

[0005] (3) Spraying insulating materials (such as silicone rubber) can prevent current conduction and is used in power or anti-static applications. The spraying color (such as yellow warning color) is easy to identify or complies with safety regulations.

[0006] (4) Stainless steel surfaces may have micropores that can breed bacteria or adsorb contaminants. A food-grade epoxy coating is applied to ensure cleanliness in accordance with FDA or EU 1935 / 2004 standards.

[0007] However, on the PTFE metal hose coating production line, the PTFE metal hoses are mostly hoisted and transported directly by clamping mechanisms. During the hoisting process, the hoses are prone to shaking due to their characteristics, which greatly reduces the stability and safety of the PTFE metal hose hoisting process. Summary of the Invention

[0008] The purpose of this invention is to provide an automatic hoisting device for a PTFE metal hose spraying production line. Through the structural design of the hoisting mechanism, hose clamping mechanism, and hose positioning mechanism, the problems in the background art mentioned above are solved.

A limiting plate and a limiting ring are respectively fixed on the inner wall of the vertical guide tube. The limiting plate is set close to the top of the vertical guide tube, and the limiting ring is set close to the bottom of the vertical guide tube. A limiting slide rail is fixedly provided on the inner wall of the vertical guide tube.

[0014] In this embodiment of the invention, an air supply device is installed on the top of the bearing hanger, and an air supply pipe is connected to the air outlet of the air supply device. The air supply pipe is connected to a limiting pipe, and the limiting pipe is connected to a vertical guide tube through a first guide member. A second guide member is installed on the top of the bearing hanger and is connected to the vertical guide tube. The first guide member and the second guide member are coaxially arranged, and a vent pipe is connected to the peripheral side of the second guide member. A solenoid valve is fixedly installed on the vent pipe.

[0015] In this embodiment of the invention, a piston sealing component is slidably disposed inside the limiting pipe, a moving rod is fixed at the bottom of the piston sealing component, a force-bearing moving plate is fixed at the bottom of the moving rod, a limiting slide is opened on the side of the limiting pipe located below the bearing hanger, and a counterweight component that slides with the limiting slide is fixed on the side of the moving rod.

[0016] In this embodiment of the invention, the steel rope traction unit includes guide rope wheels installed on both sides of the lower hoisting opening. The top of the bearing frame has guide rope openings corresponding to the guide rope wheels. A vertical connecting plate is fixedly installed on the top of the bearing frame. Two winding shafts are symmetrically rotated on the vertical connecting plate. A steel rope winding wheel and a transmission wheel are fixedly installed on the winding shafts respectively. The two transmission wheels are connected by a transmission belt. A traction motor connected to the corresponding winding shaft is installed on one side of the vertical guide tube.

[0017] In this embodiment of the invention, the hose clamping mechanism includes a clamping control shaft rotatably disposed between mounting plates. A toothed clamping part coaxial with the clamping control shaft is disposed on the outer side of the clamping control shaft. The flange support is fixedly disposed on the peripheral side of the toothed clamping part. The toothed clamping part and the clamping control shaft are connected by a fixing member.

[0018] In this embodiment of the invention, the hose positioning mechanism includes a guiding piston that slides inside the vertical guide tube. A guiding channel is provided on the peripheral side of the guiding piston, and a limiting port that slides with the limiting slide rail is provided on the peripheral side of the guiding piston. An outer air guide tube is fixed to the bottom of the guiding piston. The guiding channel is connected to the inner cavity of the outer air guide tube. An inner air guide tube is slidably fitted inside the outer air guide tube. A steel rope connecting part is fixed to the peripheral side of the inner air guide tube. A hollow mounting part is provided at the bottom of the inner air guide tube. An airbag is provided in the annular cavity on the peripheral side of the hollow mounting part. An air supply hole communicating with the inside of the airbag is provided on the inner wall of the hollow mounting part.

[0019] The present invention has the following beneficial effects: 1. The present invention inserts the first limiting pipe and the second limiting pipe into the two opposite flange holes on the PTFE metal hose, respectively. The inner air guide pipe drives the outer air guide pipe to move downward together. When the connecting piston moves down and disengages from the limiting plate and rests against the limiting ring, the connecting holes on the connecting piston are concentrically aligned with the first connecting element and the second connecting element. As the hose positioning mechanism continues to descend to the set position, the hollow mounting part, the inner air guide pipe and the outer air guide pipe achieve the initial positioning of the PTFE metal hose, so as to prevent the PTFE metal hose from shaking significantly during the hoisting process, thereby improving the stability and safety of the PTFE metal hose during the hoisting process.

[0020] 2. In this invention, the air entering the hollow mounting section enters the airbag through various air inlets, causing it to inflate and expand. This expands the airbag tightly against the inner wall of the PTFE metal hose. Then, the entire hose positioning mechanism is lowered a certain distance by a steel cable. The gripping force between the expanded airbag and the inner wall of the PTFE metal hose, as well as the gravity of the air guide tube and other components, generates a downward pulling force on the vertical PTFE metal hose. This ensures that the PTFE metal hose remains in a stable vertical state during hoisting, thus greatly preventing the PTFE metal hose from shaking during hoisting and ensuring the quality of the PTFE metal hose coating.

[0021] 3. When the linkage frame is lowered to the set position by the cylinder control, the toothed clamping part of the arc structure near the end of the flange support is rotated and inserted into the interior of the first and second limiting pipes. At this time, the flange support parts on both sides are tightly attached to the bottom of the top flange of the PTFE metal hose. Thus, the PTFE metal hose is supported by the hose clamping mechanism on both sides. During this process, the toothed clamping part inserted into the first and second limiting pipes pushes the force-receiving moving disk to move upward along the inner wall of the first limiting pipe. When the flange support part is tightly attached to the bottom of the top flange of the PTFE metal hose, the piston sealing part just achieves the sealing of the air supply pipe and the first conductive part, thus ensuring that the inflated airbag is in an inflated state.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] For a specific implementation example, please refer to Implementation Example 1. Figure 1-15This invention relates to an automatic hoisting device for a PTFE metal hose spraying production line, comprising a hoisting mechanism 1, two hose clamping mechanisms 2 symmetrically installed at the bottom of the hoisting mechanism 1, and a hose positioning mechanism 3 slidably installed on the axis of the hoisting mechanism 1. The hose clamping mechanisms 2 are used to clamp and fix the PTFE metal hose 4, and the hose positioning mechanism 3 is used for axial positioning of the PTFE metal hose 4. The hoisting mechanism 1 includes a hoisting port 101, rocker-type transmission parts symmetrically arranged on both sides of the hoisting port 101, a lifting drive part for driving the two rocker-type transmission parts to rotate synchronously, and a steel rope traction part; the hoisting port 101 is... Limiting pipe 102 and limiting pipe 2 103 are fixed on both sides respectively. Limiting pipe 102 and limiting pipe 2 103 are used to connect with the flange holes on the PTFE metal hose 4. The rocker-type transmission part is set one-to-one with the hose clamping mechanism 2, and the hose clamping mechanism 2 is slidably connected to the corresponding rocker-type transmission part. The circumferential movement of the flange support 201 on the hose clamping mechanism 2 is realized by the lifting drive part and the rocker-type transmission part. The movable end of the steel rope on the steel rope traction part is connected to the hose positioning mechanism 3. The steel rope traction part is used to transport the hose positioning mechanism 3 into the clamped and fixed PTFE metal hose 4.

[0042] In this embodiment of the invention, such as Figure 4 and Figure 12 As shown, the hoisting mechanism 1 also includes a bearing hanger 104. The hoisting port 101 is located at the axial position of the bearing hanger 104. A vertical guide tube 105 is fixedly installed inside the hoisting port 101 above the bearing hanger 104. A suspension bracket 106 is fixedly installed on the top of the vertical guide tube 105. The suspension bracket 106 and the bearing hanger 104 are fixedly connected by a limiting guide 107 (to improve the structural strength of the entire hoisting mechanism 1). Limiting pipe one 102 and limiting pipe two 103 are both fixedly installed on the bearing hanger 104.

[0043] Furthermore, the top of the support frame 104 is symmetrically provided with two limiting guide ports 108, and the bottom of the support frame 104 is symmetrically provided with two limiting guide ports 109. The lifting drive unit includes two symmetrically arranged lifting drive frames 110. The lifting drive frames 110 are slidably engaged inside the limiting guide ports 108 (to ensure that the lifting drive frames 110 move up and down smoothly). The vertical guide tube 105 is fitted with a linkage frame 111 fixed to the lifting drive frame 110. The linkage frame 111 is slidably arranged between the two limiting guide frames 107 (to ensure that the lifting drive frame 110 moves up and down smoothly). The output end of the cylinder 112 installed at the bottom of the suspension frame 106 is connected to the linkage frame 111, that is, the lifting drive frame 110 is controlled to move up and down through the action of the cylinder 112 and the linkage frame 111.

[0044] In this embodiment of the invention, such as Figure 7 and Figure 12As shown, the rocker-type transmission unit includes rocker shafts 113 rotatably mounted on opposite sides of the hoisting opening 101. A transmission rocker 114 is fixedly mounted on the periphery of the rocker shaft 113. Two transmission slides 115 are symmetrically arranged on the transmission rocker 114. A transmission notch 116 communicating with the lower transmission slide 115 is opened on the surface of the transmission rocker 114. A first linkage rod connected to the corresponding lifting drive frame 110 is slidably mounted inside the upper transmission slide 115. During the process of the lifting drive frame 110 moving up and down to drive the first linkage rod to move synchronously, the first linkage rod pushes the transmission rocker 114 to rotate. During this process, the first linkage rod slides relative to the corresponding transmission slide 115.

[0045] Furthermore, a support ring 117 coaxially arranged below the support hanger 104 is provided. Two support plates 118 are symmetrically fixed to the top of the support ring 117. Limiting pipe one 102 and limiting pipe two 103 are respectively fixedly connected to the corresponding support plates 118. Two sets of mounting plates 119 are symmetrically fixed on the inner wall of the support ring 117. Each set of mounting plates 119 is provided with a guide seat 120 fixed to the support ring 117 on its inner side. A limiting plate 121 and a limiting ring 122 are respectively fixed on the inner wall of the vertical guide tube 105. The limiting plate 121 is set close to the top of the vertical guide tube 105, and the limiting ring 122 is set close to the bottom of the vertical guide tube 105. A limiting slide rail 123 is fixedly provided on the inner wall of the vertical guide tube 105.

[0046] In this embodiment of the invention, such as Figure 8 , Figure 9 and Figure 10 As shown, a gas supply device 124 is installed on the top of the support hanger 104. The gas supply device 124 is connected to a gas supply pipe 125 at its outlet. The gas supply pipe 125 is connected to a limiting pipe 102. The limiting pipe 102 is connected to the vertical guide tube 105 through a first guide member 126. A second guide member 127 connected to the vertical guide tube 105 is installed on the top of the support hanger 104. The first guide member 126 and the second guide member 127 are coaxially arranged. A vent pipe 128 is connected to the circumferential side of the second guide member 127. A solenoid valve 129 is fixedly installed on the vent pipe 128.

[0047] Furthermore, a piston sealing component 130 is slidably installed inside the limiting pipe 102. A moving rod 131 is fixed to the bottom of the piston sealing component 130, and a force-bearing moving plate 132 is fixed to the bottom of the moving rod 131. A limiting slide 133 located below the bearing hanger 104 is opened on the periphery of the limiting pipe 102. A counterweight 134 that slides with the limiting slide 133 is fixed on the periphery of the moving rod 131. This ensures that the piston sealing component 130 will not deflect during its up and down movement.

[0048] Specific embodiment two, based on specific embodiment one, such as Figure 4 , Figure 6 and Figure 13 As shown, the steel rope traction unit includes guide rope wheels 135 installed on both sides of the lifting opening 101 below. The top of the bearing frame 104 has guide rope openings 136 corresponding to the guide rope wheels 135. A vertical connecting plate 137 is fixedly installed on the top of the bearing frame 104. Two winding shafts 138 are symmetrically rotated on the vertical connecting plate 137. Steel rope winding wheels 139 and transmission wheels 140 are fixedly installed on the winding shafts 138 respectively. The two transmission wheels 140 are connected by a transmission belt 141. A traction motor 142 connected to the corresponding winding shaft 138 is installed on one side of the vertical guide tube 105. In this way, the synchronous rotation of the two winding shafts 138 can be controlled by the traction motor 142, thereby realizing the synchronous winding or releasing action of the two steel rope winding wheels 139.

[0049] In this embodiment of the invention, such as Figure 14 As shown, the hose clamping mechanism 2 includes a clamping control shaft 202 rotatably disposed between mounting plates 119. A toothed clamping part 203 (arc-shaped structure) coaxial with the clamping control shaft 202 is disposed on the outer side of the clamping control shaft 202. A flange support 201 is fixedly disposed on the peripheral side of the toothed clamping part 203. The toothed clamping part 203 is connected to the clamping control shaft 202 by a fastener. A toothed drive plate 204 is engaged on one side of the toothed clamping part 203 (the toothed drive plate 204 slides within the guide seat 120). A U-shaped seat 205 is fixed to the top of the toothed drive plate 204 and slides with the limiting guide port 109. The limiting guide port 109 and the guide seat 120 together... The same action ensures the smooth up-and-down movement of the toothed drive plate 204 and the U-shaped seat 205. The U-shaped seat 205 is slidably engaged inside the transmission notch 116. The second linkage rod 206, which is fixed at the top of the U-shaped seat 205, is slidably engaged inside the transmission slide 115 below. That is, during the up-and-down movement of the lifting drive frame 110, the first linkage rod moves synchronously. The first linkage rod pushes the transmission rocker 114 to rotate, and then the transmission rocker 114 drives the second linkage rod 206 to move up and down. During this process, the first linkage rod slides relative to the corresponding transmission slide 115, and at the same time, the second linkage rod 206 slides relative to the corresponding transmission slide 115.

[0050] In this embodiment of the invention, such as Figure 2 and Figure 15As shown, the hose positioning mechanism 3 includes a guiding piston 301 that slides inside the vertical guide tube 105. A guiding channel 302 is provided on the circumferential side of the guiding piston 301, and a limiting port 303 that slides with the limiting slide rail 123 is also provided on the circumferential side of the guiding piston 301. This structure ensures that the guiding piston 301 will not deflect during its up-and-down movement. An outer air guide tube 304 is fixed to the bottom of the guiding piston 301. The guiding channel 302 communicates with the inner cavity of the outer air guide tube 304. An inner air guide tube 305 is slidably fitted inside the outer air guide tube 304, and its circumferential side is fixed... There is a steel rope connection part 306, and two steel ropes are fixed at the top of the steel rope connection part 306. The steel rope connection part 306 can be moved up and down by pulling the steel ropes. The bottom of the air guide inner tube 305 is connected to a hollow mounting part 307. An airbag 308 is installed in the annular cavity on the periphery of the hollow mounting part 307. The inner wall of the hollow mounting part 307 has an air supply hole that communicates with the inside of the airbag 308. The air that enters the air guide outer tube 304 through the guide channel 302 enters the hollow mounting part 307 through the air guide inner tube 305, and then enters the airbag 308 through the various air supply holes to inflate it.

[0051] Initially, the conducting piston 301, under the action of the steel cable, abuts against the limiting plate 121, and the top of the air guide pipe 305 abuts against the top of the inner part of the conducting piston 301. The hollow mounting part 307 is located between the bearing hanger 104 and the support ring 117. The linkage frame 111 is in a lower position under the action of the cylinder 112. At this time, the toothed drive plate 204 is close to the bottom of the bearing hanger 104, and the end of the toothed clamping part 203 near the flange support 201 deviates from the limiting pipe 102 (that is, the flange support 201 is close to the toothed drive plate 204 at this time). Then, the traveling mechanism on the guide rail carries... The lifting mechanism moves together to the top of the loading and unloading area and aligns with a PTFE metal hose 4 (a hose placement rack is provided in the loading and unloading area, on which a certain number of PTFE metal hoses 4 are placed, and the flange at the top of the PTFE metal hose 4 is supported by support rods on both sides). Then, the lifting mechanism gradually controls the hoisting mechanism 1 to move downward until it reaches the set position (set by the control system). At this time, the first limiting pipe 102 and the second limiting pipe 103 are respectively inserted into the two corresponding flange holes on the flange at the top of the PTFE metal hose 4, thus achieving the limiting of the PTFE metal hose 4 at the bottom of the hoisting mechanism 1.

[0052] Next, the traction motor 142 controls the two winding shafts 138 to rotate synchronously, thereby achieving synchronous rotation of the two steel rope winding wheels 139. During this process, the steel rope on the two steel rope winding wheels 139 is gradually released. Under the action of the steel rope, the entire hose positioning mechanism 3 gradually moves downward. The air guide inner pipe 305 drives the air guide outer pipe 304 to move downward together. When the connecting piston 301 moves downward and disengages from the limiting plate 121 and rests against the limiting ring 122, the connecting hole 302 on the connecting piston 301 is concentrically aligned with the first connecting element 126 and the second connecting element 127. Since the counterweight 134 is initially against the bottom of the limiting slide 133, the force-bearing moving plate 132 is close to the bottom of the limiting pipe 102, and the piston sealing element 130 is in a position where... Below the first guide element 126 (i.e., the first guide element 126, the limiting pipe 102, and the gas supply pipe 125 are interconnected at this time), the hose positioning mechanism 3 continues to descend via a steel rope until the hollow mounting part 307 reaches the set position inside the PTFE metal hose 4 (i.e., the hollow mounting part 307 is close to the lower flange on the PTFE metal hose 4 at this time). During this process, the inner gas guide pipe 305 slides downward relative to the outer gas guide pipe 304, while the outer gas guide pipe 304 no longer descends. At this time, the hollow mounting part 307, the inner gas guide pipe 305, and the outer gas guide pipe 304 achieve preliminary positioning of the PTFE metal hose 4 to prevent the PTFE metal hose 4 from shaking significantly during hoisting, thereby improving the stability and safety of the PTFE metal hose 4 during hoisting.

[0053] Subsequently, air is supplied through the air supply device 124 along the air supply pipe 125 to the limiting pipe 102, and then enters the outer air guide pipe 304 through the first guide member 126 and the guide channel 302. It then enters the inner cavity of the hollow mounting part 307 through the inner air guide pipe 305, and finally enters the airbag 308 through various air outlets, causing it to inflate. This inflated airbag 308 then adheres tightly to the inner wall of the PTFE metal hose 4. The entire hose positioning mechanism 3 is then lowered a certain distance (set by the control system) by a steel cable. The inflated airbag 308 then presses firmly against the inner wall of the PTFE metal hose 4. The gripping force between the inflated airbag 308 and the inner wall of the PTFE metal hose 4, along with the gravity of components such as the air guide tube 305, generates a downward pulling force on the vertical PTFE metal hose 4. This ensures that the PTFE metal hose 4 remains in a stable, upright position during hoisting, greatly preventing swaying. Subsequently, the cylinder 112 controls the two lifting drive frames 110 on the linkage frame 111 to move upward synchronously. The first linkage rod at the bottom of the lifting drive frame 110 drives the transmission rocker plate 114 to rotate (e.g., Figure 3As shown), during the rotation of the transmission rocker 114, the second linkage rod 206 drives the U-shaped seat 205 and its toothed drive plate 204 to move upward. The upward-moving toothed drive plate 204 drives the toothed clamping part 203 to rotate. When the linkage frame 111 is lowered to the set position by the cylinder 112, the end of the arc-shaped toothed clamping part 203 near the flange support 201 rotates and inserts into the limiting pipe one 102 and the limiting pipe two 103. At this time, the flange support parts 201 on both sides are tightly attached to the PTFE metal hose 4. At the bottom of the top flange, the PTFE metal hose 4 is supported by the hose clamping mechanism 2 on both sides. During this process, the toothed clamping part 203 inserted into the limiting pipe 102 and the limiting pipe 203 pushes the force-receiving moving plate 132 to move upward along the inner wall of the limiting pipe 102. When the flange support 201 is in close contact with the bottom of the top flange of the PTFE metal hose 4, the piston sealing part 130 just blocks the gas supply pipe 125 and the first guide part 126, thus ensuring that the inflated airbag 308 is in an inflated state.

[0054] Next, the lifting mechanism 1 is moved upwards again to return to its initial position via the lifting mechanism. Then, the traveling mechanism moves along the guide rail to lift the clamped and fixed PTFE metal hose 4 to directly above the spraying area. A spraying cylinder is provided in the spraying area, and several nozzles are arranged in a circumferential array on the inner wall of the spraying cylinder. Then, the lifting mechanism 1 is moved downwards again to the set position via the lifting mechanism. At this time, the lifted PTFE metal hose 4 enters the spraying cylinder. After the spraying process is completed, the lifting mechanism 1 is moved upwards again to return to its initial position via the lifting mechanism. The traveling mechanism moves along the guide rail to lift the sprayed PTFE metal hose 4 to the loading and unloading area. Then, the lifting mechanism 1 is lowered to the set position via the lifting mechanism. At this time, the PTFE metal hose 4 falls back onto the hose placement rack and is supported by the support rod. The solenoid valve on the vent pipe 128 is then opened. 129, so that the air in the airbag 308 is discharged along the inlet, hollow mounting part 307, inner air guide tube 305, outer air guide tube 304, guide channel 302, second guide member 127 and vent pipe 128. In this way, the internal support effect of the airbag 308 on the inner wall of the PTFE metal hose 4 is released. After the entire hose positioning mechanism 3 is lifted and reset by controlling the steel rope, the solenoid valve 129 is closed. The linkage frame 111 is lowered again by controlling the cylinder 112 to complete the reset. At this time, the toothed clamping parts 203 on both sides and the flange support 201 are released from the flange support. Then, the lifting mechanism 1 is moved up and reset by controlling the lifting mechanism and moved above the next PTFE metal hose 4. The lifting mechanism 1 is lowered to the set position by controlling the lifting mechanism. The same control method is used to successively realize the lifting operation of a certain number of PTFE metal hoses 4.
