Description

Technical Field

[0001] The invention belongs to the technical field of cable tray shaping, in particular to a cable tray shaping device. Background Art

[0002] Cable tray is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems. It has good effects on shielding interference of control cables and protecting cables in heavy corrosive environments. However, after long-term use, cable trays will be deformed, and the deformed cable trays cannot be reused, resulting in great waste.

[0003] Publication No. CN116586462A discloses a cable tray shaping device, comprising a conveyor belt symmetrically arranged for conveying the cable tray, a squeezing mechanism arranged between the two conveyor belts for squeezing the two side walls of the cable tray, and a rolling mechanism for repairing the bottom and two side arms of the cable tray; the conveyor belt continuously conveys the cable tray, and when the cable tray passes between the two conveyor belts, the squeezing mechanism squeezes the two side walls of the cable tray, and the rolling mechanism continuously squeezes the bottom and two side arms of the cable tray, thereby realizing the shaping and resetting of the cable tray, facilitating the reuse of the cable tray and reducing resource waste.

[0004] In the above scheme, when the bridge is shaped, the extrusion mechanism first extrudes and shapes the two side walls of the bridge, and then the extrusion mechanism releases the extrusion of the bridge, and the bridge is conveyed by the conveyor belt to pass through the rolling mechanism for rolling and shaping. However, the area of ​​the bridge that can be shaped by the extrusion mechanism at one time is limited, and the spacing between the extrusion rollers in the rolling mechanism is fixed. After the bridge is initially shaped, most of the bridge is still in a deformed state. After the extrusion mechanism releases the bridge, the bridge is still deformed and distorted, and is not straight. Therefore, the conveyor belt cannot bring the bridge into the rolling mechanism for shaping. Secondly, the extrusion mechanism shapes part of the bridge at one time. Since the bridge is elastic, the bridge will rebound to a certain extent after shaping, resulting in insufficient shaping of the bridge. For this reason, the present invention provides a cable bridge shaping device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a cable tray shaping device described in the present invention comprises a belt transmission mechanism, a support frame is fixedly installed on the belt transmission mechanism, two groups of side shaping parts are arranged on the support frame, and a first hydraulic oil cylinder for driving the side shaping parts is arranged on the support frame, an inner shaping device is arranged between the two groups of side shaping parts, and the inner shaping device comprises: a second hydraulic oil cylinder, the second hydraulic oil cylinder is fixedly installed on the support frame, a fixing part fixedly connected to the second hydraulic oil cylinder, an inner pressure plate arranged on both sides of the fixing part, a shaping plate movably installed in the inner pressure plate, a rectangular cavity opened in the shaping plate, a movable plate slidably connected to the rectangular cavity, three groups of first springs arranged in the rectangular cavity, a bidirectional hydraulic oil cylinder for driving the movable plate, the bidirectional hydraulic oil cylinder is fixedly installed in the fixing part, pins are arranged at both ends of the movable plate, oblique slide grooves are arranged on both sides of the rectangular cavity, and the pins are slidably connected to the oblique slide grooves;

[0011] When the first hydraulic cylinder pulls back the side shaping piece, the first hydraulic cylinder will pull the pressure block, causing the roller to lose the abutment of the inclined surface, and the shaping strip will release the extrusion on the deformed part of the outer side of the bridge frame, thereby avoiding the engagement between the side shaping piece and the outer side of the bridge frame.

[0012] Preferably, four groups of guide grooves are arranged on the support frame, two groups of rollers are rotated at the lower end of the outer pressure plate, the rollers are rollingly connected to the guide grooves, two groups of third through holes are symmetrically opened on the pressure block, the third through holes are movably connected to the third guide pillars, and the third guide pillars are fixedly mounted on the outer pressure plate;

[0013] The outer pressure plate drives the roller to roll along the guide groove, which supports and guides the movement of the outer pressure plate. Secondly, the third through hole on the pressure block slides along the third guide column, which guides the movement of the pressure block.

[0014] Preferably, the belt transmission mechanism comprises: a frame, a support frame fixedly mounted on the frame, a conveyor belt arranged in the frame, a driving roller for driving the conveyor belt, a support roller for supporting the conveyor belt, a fixing mechanism arranged on the conveyor belt, the fixing mechanism comprising a fixing plate, the fixing plate embedded and mounted on the conveyor belt, a shell fixedly mounted on the fixing plate, two groups of rotating columns rotatably mounted on the shell, a rubber sleeve fixedly mounted on the rotating column, a gear fixedly mounted on the end of the rotating column, the two groups of gears meshing with each other, a plurality of groups of support rollers are arranged, the plurality of groups of support rollers are equidistantly distributed in the conveyor belt, the support rollers and the support rollers are both rotatably mounted in the frame, a hexagonal groove is provided at the other end of the rotating column, and an avoidance groove for avoiding the shell is provided at the lower end of the fixing member;

[0015] As the rubber sleeve rotates, the protrusions on the rubber sleeve will squeeze the bridge frame, pressing the bridge frame against the fixed plate, thereby fixing the end of the bridge frame on the conveyor belt. Therefore, even if the inner side of the bridge frame is scratched against the inner shaping device, the inner shaping device can drive the bridge frame to advance.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. Place the bridge on the belt drive mechanism, then insert the end of the bridge between the side shaping piece and the inner shaping device, start the second hydraulic cylinder, the second hydraulic cylinder pushes the fixing piece to press down the bottom of the bridge, then start the first hydraulic cylinder and the two-way hydraulic cylinder at the same time, the first hydraulic cylinder pushes the side shaping piece to squeeze the outer side of the bridge, the two-way hydraulic cylinder drives the two sets of movable plates to move, the movable plate together with the first spring and the inner pressure plate moves toward the inner side of the bridge until the inner pressure plate squeezes the inner side of the bridge, at this time the movable plate continues to slide along the rectangular cavity, and the movable plate compresses the first Spring, and at the same time, the movable plate drives the pin shaft to slide along the oblique slide groove, so that the shaping plate slides upward along the inner cavity of the inner pressure plate, so that the two sides of the bridge frame are clamped between the side shaping pieces, the inner pressure plate, and the shaping plate, to achieve the shaping of the bridge frame, and then withdraw the side shaping pieces and the inner shaping device, and drive the bridge frame forward through the belt transmission mechanism. Repeat the above operation and repeatedly shape the bridge frame. Compared with the prior art, the bridge frame is advanced forward through the belt transmission mechanism, so that the side shaping pieces and the inner shaping device can repeatedly shape the bridge frame many times, so that the bridge frame can be shaped more thoroughly.

[0018] 2. The first hydraulic cylinder pushes the pressure block, and the pressure block moves toward the outer side of the bridge together with the second spring and the outer pressure plate. During this process, if the upper and lower sides of the outer side of the bridge are deformed, the deformation will push the shaping bar, causing the shaping bar to rotate together with the receiving plate and the roller until the outer pressure plate squeezes the outer side of the bridge. At this time, the pressure block will be inserted into the outer pressure plate and compress the second spring. At the same time, the inclined surface on the pressure block pushes the roller, and the roller rolls along the inclined surface to make the shaping bar, the receiving plate, and the roller return to a horizontal state. The shaping bar will squeeze the deformed part of the outer side of the bridge until the pressure block hits the inner wall of the outer pressure plate. At the same time, the inclined surface keeps against the roller to achieve shaping of the outer side of the bridge. Therefore, when the first hydraulic cylinder pulls back the side shaping part, the first hydraulic cylinder will pull the pressure block to make the roller lose the support of the inclined surface, and the shaping bar will release the extrusion of the deformed part of the outer side of the bridge, thereby avoiding the engagement between the side shaping part and the outer side of the bridge.

[0019] 3. Insert the end of the bridge frame between the rotating column and the fixed plate, and then use a group of motors to drive the driving roller to rotate, so that the conveyor belt moves in a circle around the driving roller and multiple groups of support rollers, so that the end of the bridge frame moves toward the side shaping piece and the inner shaping device until the end of the bridge frame is located between the side shaping piece and the inner shaping device, and the shell enters the avoidance groove, and then use the hexagonal wrench to screw the hexagonal slot to rotate the rotating column together with the corresponding rubber sleeve and gear. The gear rotates together with the other group of rotating columns together with the rubber sleeve through another group of gears. As the rubber sleeve rotates, the raised part on the rubber sleeve will squeeze the bridge frame, so that the pressure bridge frame is pressed on the fixed plate, so that the end of the bridge frame is fixed on the conveyor belt. Therefore, even if the inner side of the bridge frame is scratched with the inner shaping device, the inner shaping device can drive the bridge frame to advance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1:

[0032] like Figures 1 to 4As shown, a cable tray shaping device described in an embodiment of the present invention includes a belt transmission mechanism 1, a support frame 2 is fixedly installed on the belt transmission mechanism 1, two groups of side shaping members 3 are arranged on the support frame 2, and a first hydraulic oil cylinder 4 for driving the side shaping members 3 is arranged on the support frame 2, an inner shaping device 5 is arranged between the two groups of side shaping members 3, and the inner shaping device 5 includes: a second hydraulic oil cylinder 501, the second hydraulic oil cylinder 501 is fixedly installed on the support frame 2, a fixing member 502 fixedly connected to the second hydraulic oil cylinder 501, and a fixing member 502 arranged on both sides of the fixing member 502 An inner pressure plate 503, a shaping plate 504 movably installed in the inner pressure plate 503, a rectangular cavity 505 opened in the shaping plate 504, a movable plate 506 slidably connected to the rectangular cavity 505, three groups of first springs 507 arranged in the rectangular cavity 505, a two-way hydraulic cylinder 508 for driving the movable plate 506, the two-way hydraulic cylinder 508 is fixedly installed in the fixing part 502, pins 5061 are arranged at both ends of the movable plate 506, and oblique sliding grooves 5051 are arranged on both sides of the rectangular cavity 505, and the pins 5061 are slidably connected to the oblique sliding grooves 5051.

[0033] Specifically, the belt transmission mechanism 1 is used to transmit the bridge frame 6. The belt transmission mechanism 1 transmits the bridge frame 6 by making a circular motion through the transmission belt 102. When the bridge frame 6 needs to be shaped, the bridge frame 6 is placed on the belt transmission mechanism 1, and then the end of the bridge frame 6 is inserted between the side shaping member 3 and the inner shaping device 5, and the second hydraulic cylinder 501 is started. The second hydraulic cylinder 501 pushes the fixing member 502 to press down the bottom of the bridge frame 6, and then the first hydraulic cylinder 4 and the two-way hydraulic cylinder 508 are started at the same time. The first hydraulic cylinder 4 pushes the side shaping member 3 to squeeze the outer edge of the bridge frame 6, and the two-way hydraulic cylinder 508 drives the two sets of movable plates 506 to move. The movable plates 506, together with the first spring 507 and the inner pressure plate 503, move toward the inner side of the bridge frame 6 until the inner pressure plate 503 is squeezed to the inner side of the bridge frame 6. At this time, the movable plate 506 continues to slide along the rectangular cavity 505, and the movable plate 506 compresses the first spring 507. At the same time, the movable plate 506 drives the pin shaft 5061 to slide along the oblique slide groove 5051, so that the shaping plate 504 slides upward along the inner cavity of the inner pressure plate 503, so that the two sides of the bridge frame 6 are clamped between the side shaping parts 3, the inner pressure plate 503, and the shaping plate 504, so as to realize the shaping of the bridge frame 6, and then withdraw the side shaping parts 3 and the inner shaping device 5, and drive the bridge frame 6 forward through the belt transmission mechanism 1, repeat the above operation, and repeatedly shape the bridge frame 6. Compared with the prior art, the bridge frame 6 is advanced forward by the belt transmission mechanism 1, so that the side shaping parts 3 and the inner shaping device 5 can repeatedly shape the bridge frame 6 many times, so that the bridge frame 6 is shaped more thoroughly.

[0034] like Figure 2 and Figure 4As shown, two groups of first guide columns 5021 are symmetrically installed on the fixing member 502, two groups of first through holes 201 are symmetrically opened on the support frame 2, the first guide columns 5021 are movably inserted into the first through holes 201, two groups of second through holes 5022 are opened at both ends of the fixing member 502, two groups of second guide columns 5031 are arranged at both ends of the inner pressure plate 503, and the second guide columns 5031 are movably inserted into the second through holes 5022.

[0035] Specifically, when the fixing member 502 presses down the bottom of the bridge frame 6, the first guide column 5021 on the fixing member 502 slides along the first through hole 201, guiding the movement of the fixing member 502. Secondly, when the inner pressure plate 503 moves toward the inner side of the bridge frame 6, the inner pressure plate 503 drives the second guide column 5031 to slide along the second through hole 5022, also guiding the movement of the inner pressure plate 503.

[0036] like Figure 5 and Figure 6 As shown, the side shaping member 3 includes: an outer pressure plate 301, two sets of rotating shafts 302 symmetrically installed on the upper and lower sides of the outer pressure plate 301, a receiving plate 303 fixedly connected to the rotating shaft 302, a shaping strip 304 fixedly connected to one end of the receiving plate 303, a roller 305 rotatably installed on the other end of the receiving plate 303, a second spring 306 arranged in the outer pressure plate 301, a pressure block 307 movably plugged into the outer pressure plate 301, the pressure block 307 is fixedly connected to the first hydraulic cylinder 4, and two sets of inclined surfaces 3071 are symmetrically opened at the end of the pressure block 307, and the inclined surface 3071 is used to push the roller 305.

[0037] Specifically, the weight of the shaping strip 304 is much greater than that of the roller 305. In the initial state, the shaping strip 304, the receiving plate 303, and the roller 305 are in a horizontal state. When the side shaping member 3 squeezes the outer edge of the bridge frame 6, the side shaping member 3 will engage with the outer edge of the bridge frame 6. If the side edge of the bridge frame 6 is severely deformed, the engagement force between the side shaping member 3 and the outer edge of the bridge frame 6 will be relatively tight. When the side shaping member 3 is withdrawn, the side shaping member 3 will drive the bridge frame 6 to move back together. The belt transmission mechanism 1 cannot drive the bridge frame 6 to advance forward. Therefore, when the first hydraulic cylinder 4 drives the side shaping member 3 to squeeze the outer side of the bridge frame 6, the first hydraulic cylinder 4 pushes the pressure block 307, and the pressure block 307 together with the second spring 306 and the outer pressure plate 301 move toward the outer side of the bridge frame 6. In this process, if the upper and lower sides of the outer side of the bridge frame 6 are deformed, the deformation will push the shaping strip 304, so that the shaping strip 304 together with the receiving plate 303 and the roller The column 305 rotates together until the outer pressure plate 301 squeezes the outer side of the bridge frame 6. At this time, the pressure block 307 will be inserted into the outer pressure plate 301 and compress the second spring 306. At the same time, the inclined surface 3071 on the pressure block 307 pushes the roller 305. The roller 305 rolls along the inclined surface 3071 to return the shaping strip 304, the receiving plate 303, and the roller 305 to a horizontal state. The shaping strip 304 will squeeze the deformed part of the outer side of the bridge frame 6 until the bearing The pressure block 307 abuts against the inner wall of the outer pressure plate 301, and at the same time the inclined surface 3071 maintains the abutment against the roller 305, thereby realizing the shaping of the outer edge of the bridge frame 6. Therefore, when the first hydraulic cylinder 4 pulls back the side shaping member 3, the first hydraulic cylinder 4 will pull the pressure block 307, so that the roller 305 loses the abutment of the inclined surface 3071, and the shaping strip 304 will release the extrusion on the deformed part of the outer edge of the bridge frame 6, thereby avoiding the engagement between the side shaping member 3 and the outer edge of the bridge frame 6.

[0038] like Figure 5 and Figure 6 As shown, four groups of guide grooves 202 are arranged on the support frame 2, two groups of rollers 3011 are rotated at the lower end of the outer pressure plate 301, the rollers 3011 are rollingly connected to the guide grooves 202, two groups of third through holes 3072 are symmetrically opened on the pressure block 307, the third through holes 3072 are movably connected to the third guide pillars 3073, and the third guide pillars 3073 are fixedly installed on the outer pressure plate 301.

[0039] Specifically, when the outer pressure plate 301 moves toward the outer side of the bridge frame 6, the outer pressure plate 301 drives the roller 3011 to roll along the guide groove 202, thereby supporting and guiding the movement of the outer pressure plate 301. Secondly, when the pressure block 307 is inserted into the outer pressure plate 301, the third through hole 3072 on the pressure block 307 slides along the third guide column 3073, thereby guiding the movement of the pressure block 307. Embodiment 2:

[0040] like Figures 7 to 9As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a belt transmission mechanism 1 comprises: a frame 101, a support frame 2 fixedly mounted on the frame 101, a conveyor belt 102 arranged in the frame 101, a driving roller 105 for driving the conveyor belt 102, a support roller 103 for supporting the conveyor belt 102, a fixing mechanism 104 arranged on the conveyor belt 102, the fixing mechanism 104 comprising a fixing plate 1041, the fixing plate 1041 is embedded and mounted on the conveyor belt 102, a housing 1042 fixedly mounted on the fixing plate 1041, Two groups of rotating columns 1043 are rotatably mounted on the shell 1042, a rubber sleeve 1044 is fixedly mounted on the rotating column 1043, and a gear 1045 is fixedly mounted on the end of the rotating column 1043. The two groups of gears 1045 are meshed with each other. A plurality of supporting rollers 103 are provided, and the plurality of supporting rollers 103 are equidistantly distributed in the conveyor belt 102. The supporting rollers 103 and the supporting rollers 103 are both rotatably mounted in the frame 101. A hexagonal groove 421 is provided at the other end of the rotating column 1043, and an avoidance groove 5023 for avoiding the shell 1042 is provided at the lower end of the fixing member 502.

[0041] Specifically, the rubber sleeve 1044 is an irregular columnar structure, and the inner shaping device 5 is close to the inner side of the bridge frame 6. If the deformation of a certain section of the bridge frame 6 is large, when the belt transmission mechanism 1 drives the bridge frame 6 to advance, the inner side of the bridge frame 6 will inevitably scrape against the inner shaping device 5, and the scraping will hinder the movement of the bridge frame 6, so that the next area of ​​the bridge frame 6 cannot be shaped. Therefore, when the bridge frame 6 is placed on the belt transmission mechanism 1, the end of the bridge frame 6 is inserted between the rotating column 1043 and the fixed plate 1041, and then a group of motors drives the driving roller 105 to rotate, so that the conveyor belt 102 moves in a circle around the driving roller 105 and the multiple groups of support rollers 103, so that the end of the bridge frame 6 moves toward between the side shaping piece 3 and the inner shaping device 5 until the bridge frame 6 is The end of the frame 6 is located between the side shaping piece 3 and the inner shaping device 5, and the shell 1042 enters the avoidance groove 5023, and then the hexagonal slot 421 is screwed with an Allen wrench to rotate the rotating column 1043 together with the corresponding rubber sleeve 1044 and the gear 1045. The gear 1045 causes another set of rotating columns 1043 to rotate together with the rubber sleeve 1044 through another set of gears 1045. As the rubber sleeve 1044 rotates, the raised portion on the rubber sleeve 1044 will squeeze the bridge frame 6, so that the pressure bridge frame 6 is pressed on the fixed plate 1041, so that the end of the bridge frame 6 is fixed on the conveyor belt 102. Therefore, even if the inner side of the bridge frame 6 is scratched with the inner shaping device 5, the inner shaping device 5 can drive the bridge frame 6 to advance.

[0042] Working principle: put the bridge frame 6 on the belt transmission mechanism 1, insert the end of the bridge frame 6 between the rotating column 1043 and the fixed plate 1041, and then drive the driving roller 105 to rotate through a group of motors, so that the conveyor belt 102 moves in a circle around the driving roller 105 and multiple groups of supporting rollers 103, so that the end of the bridge frame 6 moves toward the side shaping member 3 and the inner shaping device 5, until the end of the bridge frame 6 is located between the side shaping member 3 and the inner shaping device 5, and the shell 104 2 enters the avoidance groove 5023, and then uses the hexagonal wrench to screw the hexagonal slot 421, so that the rotating column 1043 rotates together with the corresponding rubber sleeve 1044 and the gear 1045, and the gear 1045 causes another set of rotating columns 1043 and the rubber sleeve 1044 to rotate together through another set of gears 1045. As the rubber sleeve 1044 rotates, the raised portion on the rubber sleeve 1044 presses the bridge frame 6, so that the bridge frame 6 is pressed on the fixing plate 1041;

[0043] Start the second hydraulic cylinder 501, which pushes the fixing part 502 to press down the bottom of the bridge frame 6, and then start the first hydraulic cylinder 4 and the two-way hydraulic cylinder 508 at the same time. The first hydraulic cylinder 4 pushes the side shaping part 3 to squeeze the outer side of the bridge frame 6, and the two-way hydraulic cylinder 508 drives the two sets of movable plates 506 to move. The movable plate 506, together with the first spring 507 and the inner pressure plate 503, moves toward the inner side of the bridge frame 6 until the inner pressure plate 503 is squeezed to the inner side of the bridge frame 6. At this time, the movable plate 506 continues to slide along the rectangular cavity 505, and the movable plate 506 compresses the first spring 507. At the same time, the movable plate 506 drives the pin 5061 to slide along the oblique slide groove 5051, so that the shaping plate 504 slides upward along the inner cavity of the inner pressure plate 503;

[0044] When the first hydraulic cylinder 4 drives the side shaping member 3 to squeeze the outer side of the bridge frame 6, the first hydraulic cylinder 4 pushes the pressure block 307, and the pressure block 307 moves toward the outer side of the bridge frame 6 together with the second spring 306 and the outer pressure plate 301. During this process, if the upper and lower sides of the outer side of the bridge frame 6 are deformed, the deformation will push the shaping strip 304, so that the shaping strip 304 rotates together with the receiving plate 303 and the roller 305 until the outer pressure plate 301 squeezes the outer side of the bridge frame 6. At this time, the pressure block 307 will be inserted into the outer pressure plate 301 and compress the second spring 306. At the same time, the inclined surface 3071 on the pressure block 307 pushes the roller 3 05, the roller 305 rolls along the inclined surface 3071, so that the shaping strip 304, the receiving plate 303, and the roller 305 return to a horizontal state, and the shaping strip 304 will squeeze the deformed part on the outer side of the bridge frame 6 until the pressure block 307 contacts the inner wall of the outer pressure plate 301. At the same time, the inclined surface 3071 maintains contact with the roller 305, so that the two sides of the bridge frame 6 are clamped between the side shaping piece 3, the inner pressure plate 503, and the shaping plate 504, so as to realize the shaping of the bridge frame 6, and then the side shaping piece 3 and the inner shaping device 5 are withdrawn, and the bridge frame 6 is driven forward by the belt transmission mechanism 1. The above operation is repeated to repeatedly shape the bridge frame 6.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
