Description

Technical Field

[0001] The invention relates to the field of metal processing equipment, in particular to a gantry movable steel section cutting machine. Background Art

[0002] Steel is one of the essential raw materials in modern construction and industrial fields. It has good processing properties and can be processed into different types of products by cutting, welding, drilling or grinding. Common types of steel include rebars, steel pipes, steel plates and steel sections. Since some steel materials are large in size, special cutting equipment is required for cutting.

[0003] For related technologies, please refer to the Chinese patent with announcement number CN217702491U, which discloses a gantry-type H-beam cutting machine, including two symmetrically arranged guide rails, a sliding gantry arranged on the guide rails, the sliding gantry slidingly cooperates with the guide rails, and a cutting machine head slidingly cooperated with it is arranged on it, and a profile automatic positioning mechanism and a support pier spacing unified adjustment mechanism are arranged between the two guide rails; a control cabinet is arranged on the sliding gantry, and a protective baffle for preventing sparks from flying is fixedly arranged on it. The device accurately positions the profile to be processed through the profile automatic positioning mechanism arranged at the front and rear ends within the processing range, and the adjustment mechanism adjusts the spacing of the support piers to adapt to profiles of different specifications. The profile can be quickly and accurately positioned, which is convenient for subsequent cutting processing, and has a wide range of applications and strong practicality.

[0004] Regarding the above-mentioned related technologies, in addition to being used for cutting steel sections, cutting machines are also mostly used for processing steel plates. However, the cutting method is different from that of steel sections. When processing steel plates, in addition to cutting and segmenting the steel plates in the length direction, it is sometimes necessary to segment the steel plates in the width direction according to the processing requirements. In the above-mentioned cutting device, the support pier mainly provides support for the steel sections from both sides. If the steel plates are directly supported by the support piers, the supported range of the steel plates is limited. When the support at the cutting position is unstable, the steel plates are prone to fall along the cutting mouth after being cut. The installation space on the inside of the gantry is limited. If two support mechanisms are directly designed for steel sections and steel plates, it is easy to cause a narrow spacing between adjacent support mechanisms. When cutting steel plates or steel sections, the cutting machine head is prone to damage the support mechanism. Therefore, there is an urgent need for a cutting machine that can meet the needs of steel section cutting and is also suitable for processing steel plates. Summary of the invention

[0005] In order to process steel plates while meeting the needs of steel section cutting, the present application provides a gantry mobile steel section cutting machine.

[0006] The present application provides a gantry mobile steel cutting machine, which adopts the following technical solution: A gantry movable steel cutting machine comprises two guide rails, on which a gantry is provided, the gantry is slidably connected to the guide rails along the length direction of the guide rails, the gantry is provided with a cutting piece for cutting steel, a plurality of support platforms for supporting the steel are provided between the two guide rails, the support platforms are fixedly connected with a connecting arm, the connecting arm is located at one end of the support platform close to any guide rail and is detachably connected to the guide rail, a plurality of positioning platforms spaced apart from the support platforms are also provided between the two guide rails, a plurality of positioning plates are provided at the upper end of the positioning platforms, all the positioning plates are arranged along the length direction of the guide rails, the positioning plates are arranged vertically to the guide rails, and the upper ends of the positioning plates are fixedly connected with a plurality of support blocks along the length direction, a vertical plate for supporting the steel is provided at the upper end of the support platform, and with the horizontal plane as a reference, the heights of all the vertical plates are higher than the heights of the support blocks.

[0007] By adopting the above technical solution, when processing steel sections, the steel sections are placed on the support platform, the support platform supports the steel sections through the vertical plates, and the gantry drives the cutting piece to cut the steel sections under the action of the guide rails. When it is necessary to process steel plates, the support platform is released from the positioning by removing the connection between the connecting arm and the guide rails, all support platforms are removed from between the two guide rails, and the steel plates are placed on the positioning platform. The positioning plate evenly supports the steel plates through the support blocks, thereby facilitating the clamping of the steel plates, meeting the processing requirements of steel sections and facilitating the processing of steel plates.

[0008] Optionally, the vertical plate includes a fixed plate and a movable plate, and the same support platform is provided with at least one fixed plate and a movable plate, the fixed plate is fixedly connected to the support platform, the movable plate and the fixed plate are parallel to each other, and the movable plate is slidably connected to the support platform along the width direction of the guide rail, and the support platform is provided with a driving member for driving the movable plate to move.

[0009] By adopting the above technical solution, when supporting the steel section, the fixed plate and the movable plate are both located inside the steel section, so that the fixed plate and the movable plate cooperate to support the steel section. The movable plate is driven to move by the driving member, and the distance between the movable plate and the fixed plate is adjusted to be suitable for different types of steel sections.

[0010] Optionally, the fixed plate and the movable plate are provided with a plurality of avoidance grooves, which are located on the end surfaces of the movable plate and the fixed plate in contact with the steel section.

[0011] By adopting the above technical solution, when cutting steel sections, both the fixed plate and the movable plate avoid the cutting position of the cutting piece through the avoidance groove, thereby reducing the probability of the cutting piece damaging the movable plate or the fixed plate when cutting the steel sections.

[0012] Optionally, a horizontal plate is provided between adjacent support platforms, a plurality of openings are provided at the upper end of the horizontal plate along the length direction, fixed blocks are provided at both ends of the horizontal plate along the length direction, a card slot is provided on the side of the fixed block facing away from the horizontal plate, and positioning slots for placing the horizontal plate are provided at the upper ends of the movable plate and the fixed plate, and when the horizontal plate is installed in the positioning slot, the card slot and the positioning slot are connected to each other.

[0013] By adopting the above technical solution, the movable plate and the fixed plate both position the cross plate through the slots to limit the movement of the cross plate in the width direction. The fixed block is connected to the corresponding movable plate or fixed plate through the positioning slots to limit the movement of the cross plate in the length direction. When placing the steel section, the cross plate is used to increase the supporting area of ​​the fixed plate and the movable plate for the steel section, thereby improving the supporting stability of the steel section. When the cross plate supports the steel section, the cutting position of the steel section is avoided through the opening.

[0014] Optionally, the positioning platform is provided with positioning rods at both ends along the length direction, and the two positioning rods are slidably connected to the positioning platform along the length direction of the positioning plate, and the positioning platform is provided with a clamping member for driving the two positioning rods to approach or separate from each other, and the upper end of the positioning rod is connected with a clamping block along the vertical rotation, and the clamping block is located on the side where the two positioning rods are close to each other, and the positioning rod is connected with a resistance block along the horizontal sliding, and elastic members are provided between the resistance block and the positioning rod, and the two resistance blocks approach each other under the action of the corresponding elastic members, and a rotating rod is provided between the resistance block and the clamping block, one end of the rotating rod is hinged to the resistance block, and the other end is hinged to the clamping block.

[0015] By adopting the above technical solution, in the initial state, the two positioning rods are located at the ends of the positioning platform. At this time, the abutment block approaches the symmetry line between the two guide rails under the action of the elastic member. When the steel plate is placed, the two positioning rods are driven to approach each other through the clamping member, so that the positioning rod drives the abutment block to abut against the side of the steel plate. The positioning rod continues to move, and the elastic member is deformed. The abutment block and the positioning rod move relative to each other and drive the clamping block to approach the upper end surface of the steel plate through the rotating rod, thereby positioning the side and upper end of the steel plate, which is beneficial to improving the placement stability of the steel plate.

[0016] Optionally, the upper end of the fixed plate is connected to a push rod 1 along the vertical sliding manner, the upper end of the movable plate is connected to a push rod 2 along the vertical sliding manner, the support platform is provided with a driving plate arranged along the vertical lifting and lowering manner, the lower end of the push rod is fixedly connected to the driving plate, the driving plate is fixedly connected to a sliding rod corresponding to the push rod 2 along the width direction of the guide rail, the sliding rod passes through the push rod 2 and is slidably connected to the push rod 2, the upper ends of the push rod 1 and the push rod 2 are provided with moving wheels, and the moving wheels rotate along the sliding direction of the moving plate.

[0017] By adopting the above technical scheme, in the initial state, both the push rod one and the push rod two extend in the direction away from the support platform. At this time, the driving plate is in a floating state and supports the push rod two through the sliding rod. When placing the steel section, the movable plate and the fixed plate are both on the inner side of the steel section, and the steel section is in contact with the movable wheel. The push rod one and the push rod two cooperate to pre-support the steel section, and the distance between the movable plate and the fixed plate is adjusted so that the movable plate and the positioning plate cooperate to position the steel section. The moving wheel is helpful to reduce the probability of the push rod one and the push rod two damaging the steel section. When the positioning of the steel section is completed, the driving plate is operated to move downward, thereby causing the push rod one and the push rod two to drive the corresponding moving wheels to descend, so that the steel section is in contact with the fixed plate and the movable plate, and then the steel section is supported by the fixed plate and the movable plate.

[0018] Optionally, a cleaning plate is provided at the upper end of the positioning platform and is arranged perpendicular to the positioning plate. The cleaning plate is slidably connected to the positioning platform along the width direction of the guide rail. The cleaning plate is provided with a plurality of cleaning openings corresponding to the positioning plates along the length direction. When the cleaning plate moves, the positioning plate passes through the corresponding cleaning openings. A scraper for cleaning the positioning plate is fixedly connected to the cleaning plate along the side of the cleaning opening.

[0019] By adopting the above technical solution, in the initial state, the cleaning plate is located on one side of the positioning table. When cutting the steel plate, some waste slag will adhere to the outside of the positioning plate and the support block to complete the segmentation of the steel plate. After the steel plate is moved out, the cleaning plate is moved along the length direction of the positioning plate. While the positioning plate passes through the cleaning port, the cleaning plate cleans the waste slag attached to the outside of the support block and the positioning plate through the scraper, thereby reducing the probability of waste slag accumulation affecting the stability of steel plate placement.

[0020] Optionally, a collection box is fixedly connected to the lower end of the positioning platform, and the collection box is located directly below all the positioning plates. A push plate is provided in the collection box, and the push plate is slidably connected to the collection box along the width direction of the guide rail, and the lower end of the push plate is in contact with the collection box. A connecting rod is provided between the cleaning plate and the push plate, and the push plate is driven to move by the connecting rod when the cleaning plate moves.

[0021] By adopting the above technical solution, the waste residue attached to the outside of the positioning plate and the support block is cleaned by the cleaning plate and falls into the collection box under the action of gravity. When the cleaning plate moves, the push plate is driven by the connecting rod to move along the collection box. When the push plate moves, the waste residue in the collection box is pushed to one side of the collection box, thereby facilitating the cleaning of the waste residue.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When processing steel, place the steel on the support table. The support table supports the steel through the vertical plate. The gantry drives the cutting piece to cut the steel under the action of the guide rail. When processing steel plates, the support table is released from the positioning by removing the connection between the connecting arm and the guide rail. All support tables are removed from between the two guide rails. The steel plate is placed on the positioning table. The positioning plate evenly supports the steel plate through the support block, which makes it easier to clamp the steel plate. This not only meets the processing requirements of steel, but also facilitates the processing of the steel plate. 2. The movable plate and the fixed plate are positioned on the transverse plate through the slots to limit the movement of the transverse plate in the width direction. The fixed block is connected to the corresponding movable plate or fixed plate through the positioning slot to limit the movement of the transverse plate in the length direction. When placing the steel, the support area of ​​the fixed plate and the movable plate on the steel is increased through the transverse plate, thereby improving the support stability of the steel. When the transverse plate supports the steel, the cutting position of the steel is avoided through the opening; 3. In the initial state, the two positioning rods are located at the ends of the positioning platform. At this time, the resistance block approaches the symmetry line between the two guide rails under the action of the elastic member. When the steel plate is placed, the two positioning rods are driven close to each other through the clamping member, so that the positioning rod drives the resistance block to contact the side of the steel plate, and the positioning rod continues to move. At this time, the elastic member is deformed, and the resistance block and the positioning rod move relative to each other and drive the clamping block to approach the upper end surface of the steel plate through the rotating rod, thereby positioning the side and upper end of the steel plate, which is beneficial to improve the placement stability of the steel plate.

[0035] Reference Figure 2 and Figure 3, a vertical plate is provided at the upper end of the support platform 2, and the vertical plate includes a fixed plate 222 and a movable plate 221. At least one movable plate 221 and fixed plate 222 are provided. In this embodiment, two movable plates 221 are provided, and one fixed plate 222 is provided. The fixed plate 222 and the movable plate 221 are both arranged vertically, and a mounting seat corresponding to the fixed plate 222 is provided at the upper end of the support platform 2. The mounting seat is located on the side of the support platform 2 close to any guide rail 1. A groove adapted to the fixed plate 222 is opened at the upper end of the mounting seat, and the lower end of the fixed plate 222 is inserted into the groove and contacts the inner wall of the groove. The fixed plate 222 is provided with a plurality of bolts 1, and the bolts 1 pass through the fixed plate 222 and the mounting seat in sequence and are threadedly connected with the mounting seat. The fixed seat cooperates with the bolts 1 to support and position the fixed seat.

[0036] Reference Figure 2 and Figure 3 The support platform 2 is provided with a cavity, and a sliding plate is arranged in the cavity. The sliding plate is slidably connected to the support platform 2 along the length direction of the support platform 2. The support platform 2 is equipped with a driving member 23 for driving the sliding plate to move. The driving member 23 is a cylinder. The cylinder is arranged along the length direction of the support platform 2, and the output end of the cylinder is fixedly connected to the sliding plate. Two connecting plates are fixedly connected to the upper end of the sliding seat. The support platform 2 is provided with a slide groove connected to the cavity along the length direction. The connecting plates correspond to the slide groove one by one, and the connecting plates pass through the corresponding slide groove and are slidably connected to the inner wall of the slide groove. The connecting plates correspond to the moving plates 221 one by one. The upper end of the connecting plates is provided with an installation groove adapted to the moving plates 221. The moving plates 221 are inserted into the installation groove of the corresponding connecting plates and contact the inner wall of the installation groove.

[0037] Reference Figure 2 and Figure 3 A second bolt is provided between the movable plate 221 and the connecting plate. The second bolt passes through the movable plate 221 and the connecting plate in sequence, and the bolt is connected with a second nut. The second bolt and the second nut cooperate to clamp the movable plate 221 and the connecting plate, so that the sliding seat fixes the movable plate 221 through the connecting plate. When the sliding seat moves, the two movable plates 221 are driven to move synchronously.

[0038] Reference Figure 1 and Figure 2 , a plurality of positioning platforms 3 are also arranged between the two guide rails 1, and the positioning platforms 3 are spaced apart from the support platforms 2 and are parallel to each other. A plurality of positioning plates 31 are arranged perpendicularly to the guide rails 1 at the upper end of the positioning platform 3, and all the positioning plates 31 are arranged along the length direction of the guide rails 1, and a plurality of support blocks 311 are evenly arranged at the upper end of the positioning plates 31 along their own length direction. A plurality of support plates are evenly arranged at the positioning platform 3 along the width direction of the guide rails 1, and the support plates are arranged parallel to the guide rails 1, and a plurality of placement grooves are evenly arranged at the upper end of the support plates along the length direction, and a fixing groove corresponding to the placement groove is opened at the lower end of the positioning plate 31.

[0039] Reference Figure 1 and Figure 2 When installing the positioning plate 31, move the positioning plate 31 above all the supporting plates, and align the fixing grooves with the placement grooves one by one, move the positioning plate 31 downward, so that the positioning plate 31 and the supporting plate are mutually engaged through the placement grooves and the fixing grooves, and then the supporting plate supports the positioning plate 31. The positioning plate 31 is horizontally limited and supported from bottom to top. When removing the positioning plate 31, just move the positioning plate 31 out of the placement groove, which is convenient for replacing and adjusting the position of the positioning plate 31.

[0040] Reference Figure 1 and Figure 2 In the initial state, all the fixed plates 222 and the movable plates 221 are arranged vertically. At this time, the movable plates 221 and the fixed plates 222 on the same support platform 2 are close to each other, and the upper end surfaces of all the movable plates 221 and the fixed plates 222 are flush, and with the horizontal plane as a reference, the heights of the upper ends of the movable plates 221 and the fixed plates 222 are higher than the heights of the upper ends of all the support blocks 311.

[0041] Reference Figure 1 and Figure 3 When the steel section needs to be cut, the steel section is placed above all the movable plates 221 and the fixed plates 222. The steel section includes a horizontally placed diaphragm and side plates vertically fixed on both sides of the diaphragm. The movable plates 221 and the fixed plates 222 are both located between the two side plates. When the movable plates 221 and the fixed plates 222 collide with the diaphragm, the diaphragm is supported, and then the steel section is supported. The two movable plates 221 are driven to move by the driving member 23, and then the distance between the movable plates 221 and the fixed plates 222 is adjusted, so that the sides of the movable plates 221 and the fixed plates 222 that are away from each other collide with the sides of the steel section, and then the steel section is positioned in the horizontal direction.

[0042] Reference Figure 2 and Figure 3 The side of the fixed plate 222 and the movable plate 221 in contact with the steel section is provided with an avoidance groove 223, and the width of the avoidance groove 223 gradually increases in the direction away from the steel section. When cutting the steel section, the movable rod and the fixed plate 222 avoid the steel section through the avoidance groove 223, thereby reducing the probability of the cutting piece 12 damaging the fixed plate 222 or the movable plate 221.

[0043] Reference Figure 2 and Figure 4Two groups of horizontal plates 24 are provided between two adjacent support platforms 2, one group of horizontal plates 24 corresponds to two fixed plates 222, and the other group of horizontal plates 24 corresponds to two movable plates 221 close to each other on the two support platforms 2. Positioning grooves 224 are provided on the upper ends of the fixed plates 222 and the movable plates 221, and fixed blocks 242 are fixed at both ends of the horizontal plates 24. The fixed blocks 242 are vertically provided with card slots 243. When the fixed blocks 242 are inserted into the positioning grooves 224, the card slots 243 are communicated with the positioning grooves 224, and the fixed plates 222 or the movable plates 221 are in the card slots 243 along the sides of the positioning grooves 224.

[0044] Reference Figure 2 and Figure 4 The movable plate 221 and the fixed plate 222 limit the displacement of the transverse plate 24 in the width direction through the positioning groove 224, and the fixed block 242 cooperates with the corresponding fixed plate 222 or the movable plate 221 through the slot 243 to limit the displacement of the transverse plate 24 in the length direction, thereby limiting the movement of the transverse plate 24. The transverse plate 24 is located below the steel section and contacts the steel section, thereby facilitating the expansion of the contact area between the movable plate 221 and the fixed plate 222 and the steel section, and facilitating the improvement of the support stability of the steel section. The upper end of the transverse plate 24 is evenly provided with openings 241 with the same structure as the avoidance groove 223, so that the transverse plate 24 avoids the cutting part of the steel section through the openings 241.

[0045] The implementation principle of Example 1 is as follows: when processing the steel section, the movable plate 221 and the fixed plate 222 cooperate to clamp and support from the inside of the steel section. When the steel plate needs to be processed, the mounting bolts 211 are removed to contact the connecting arm 21 to position the support platform 2, thereby facilitating the support platform 2 to be moved out from between the two guide rails 1. At this time, the steel plate is placed on all the positioning plates 31 of the positioning platform 3, so that the positioning plates 31 support and position the steel plate through the support blocks 311. Further, in other embodiments, the upper end of the support block 311 is higher than the upper end of the mounting seat and the connecting plate, and then when cutting the steel plate, the movable plate 221 and the fixed plate 222 can be directly removed, thereby facilitating the processing of the steel plate while meeting the processing requirements of the steel section.

[0046] Embodiment 2: Reference Figure 5 and Figure 6The difference between this embodiment and the embodiment 1 is that the structure of the positioning platform 3 is different. The positioning platform 3 is provided with positioning rods 32 at both ends along the length direction. The positioning rods 32 are slidably connected with the positioning platform 3 along the length direction of the positioning plate 31. The positioning platform 3 is provided with a clamping member 33. The clamping member 33 includes a motor and a bidirectional lead screw. The bidirectional lead screw is arranged parallel to the positioning plate 31 and is rotatably connected with the positioning platform 3. The two ends of the bidirectional lead screw pass through the two positioning rods 32 respectively and are threadedly connected with the positioning rods 32. The motor is fixedly connected to the positioning platform 3 and is used to drive the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it drives the two positioning rods 32 to move closer to or away from each other.

[0047] Reference Figure 5 and Figure 6 The upper end of the positioning rod 32 is connected to a clamping block 321 along the vertical rotation. The two clamping blocks 321 extend in the direction of approaching each other. A resistance block 322 is also provided on the side of the positioning rod 32 that is close to each other. The resistance block 322 is slidably connected to the positioning rod 32 in the horizontal direction. When a steel plate is placed on the support block 311, the resistance block 322 is directly opposite to the side of the steel plate. An elastic member 323 is provided between the resistance block 322 and the positioning rod 32. The elastic member 323 is a spring. One end of the spring is fixedly connected to the positioning rod 32, and the other end is fixedly connected to the resistance block 322. In the natural state of the spring, the two resistance blocks 322 are in a position close to each other.

[0048] Reference Figure 5 and Figure 6 A rotating rod 324 is provided between the contact block 322 and the clamping block 321. One end of the rotating rod 324 is hinged to the clamping block 321, and the other end is hinged to the contact block 322. When the contact block 322 moves, the clamping block 321 is driven to rotate by the rotating rod 324. When the elastic member 323 is in a natural state, the clamping block 321 is in a horizontal state. When the steel plate is placed between the two positioning rods 32, the two positioning rods 32 are driven to approach each other by the clamping member 33, so that the positioning rod 32 drives the contact block 322 to contact the side of the steel plate. When the positioning rod 32 continues to move, the contact block 322 moves relative to the positioning rod 32 and drives the elastic member 323 to deform. When the contact block 322 moves relative to the positioning rod 32, the clamping block 321 is driven to approach the steel plate by the rotating rod 324, thereby pressing the steel plate. The positioning rod 32 cooperates with the clamping block 321 to limit the lateral and vertical positions of the steel plate, which is beneficial to improving the stability of the steel plate during the cutting process.

[0049] Reference Figure 5 and Figure 6The upper end of the positioning platform 3 is provided with a cleaning plate 34 perpendicular to the positioning plate 31. The cleaning plate 34 is slidably connected to the positioning platform 3 along the length direction of the positioning plate 31. The positioning platform 3 is provided with a driving motor for driving the cleaning plate 34 to move. A threaded rod is coaxially fixed to the output shaft of the driving motor. The threaded rod is arranged parallel to the positioning plate 31, and the threaded rod passes through the cleaning plate 34 and is threadedly connected to the cleaning plate 34. When the threaded rod rotates, the cleaning plate 34 is driven to move along the length direction of the positioning plate 31.

[0050] Reference Figure 5 and Figure 6 The cleaning plate 34 is provided with a plurality of cleaning openings 341 arranged in the reverse direction along the length, and the cleaning openings 341 correspond to the positioning plate 31 one by one. The positioning plate 31 and the corresponding support block 311 are both located in the corresponding cleaning openings 341. The cleaning plate 34 is provided with a plurality of scrapers 342 circumferentially along the cleaning openings 341, and the cleaning plate 34 drives the scrapers 342 to move when it moves. Some waste residue is easily generated during the cutting process of the steel plate, and the waste residue is easily adhered to the support block 311 and the positioning plate 31 under high temperature. After the cutting of the steel plate is completed, the cleaning plate 34 is driven by the driving motor to reciprocate along the positioning plate 31, so that the cleaning plate 34 cleans the waste residue on the positioning plate 31 and the support block 311 through the cleaning openings 341 and the scrapers 342.

[0051] Reference Figure 5 and Figure 6 A collecting box 35 is fixedly arranged at the lower end of the positioning platform 3. After the waste residue falls from the supporting block 311 and the positioning plate 31, it falls into the collecting box 35 under the action of gravity. A push plate 351 is arranged in the collecting box 35. A connecting rod 352 is arranged between the cleaning plate 34 and the push plate 351. When the cleaning plate 34 moves, the push plate 351 is driven to move. The push plate 351 contacts the bottom surface of the collecting box 35. When the push plate 351 moves, the waste residue in the collecting box 35 is driven to move, thereby causing the waste residue to accumulate, which is beneficial to cleaning the waste residue in the collecting box 35.

[0052] Embodiment 3: Reference Figure 7The difference between this embodiment and the first embodiment is that the structures of the fixed plate 222 and the movable plate 221 are different. The upper end of the fixed plate 222 is connected to a push rod 1 251 in a vertical sliding manner, and the upper end of the movable plate 221 is connected to a push rod 252 in a vertical sliding manner. The push rod 1 251 and the push rod 2 252 are parallel to each other. The support platform 2 is connected to a lifting plate 26 in a vertical sliding manner. A lifting cylinder for driving the lifting plate 26 to move vertically is provided in the support platform 2. The lower end of the push rod 1 251 is directly connected to the lifting plate 26, so that when the lifting plate 26 moves, the push rod 1 251 is driven to move. A sliding rod 261 is fixedly connected to the side of the lifting plate 26 away from the push rod 1 251. The sliding rod 261 is arranged along the moving direction of the movable plate 221. The sliding rod 261 passes through the push rod 2 252 in the length direction and is slidably connected to the push rod 2 252 in the length direction.

[0053] Reference Figure 7 Under the connection of the slide bar 261, when the lifting plate 26 moves, the second push rod 252 and the first push rod 251 are driven to move. And when the moving plate 221 moves in the horizontal direction, the second push rod 252 is driven to move along the slide bar 261. The upper ends of the top rod 1 251 and the top rod 252 are both hinged with moving wheels 253. In the initial state, when the steel section is placed on the fixed plate 222 and the movable plate 221, the upper ends of the top rod 1 251 and the top rod 252 are flush and higher than the fixed plate 222. At this time, the cross-plate of the steel section contacts the moving wheel 253. At this time, the movable plate 221 is operated to move away from the fixed plate 222, and the top rod 252 drives the moving wheel 253 to move. When the movable plate 221 moves to the maximum displacement, the fixed plate 222 and the movable plate 221 cooperate to clamp the steel section. At this time, the lifting plate 26 is operated to move downward, thereby driving the top rod 1 251 and the top rod 252 to move downward, so that the steel section further descends and contacts with the movable plate 221, the fixed plate 222 and the cross plate 24, which is beneficial to reduce the probability of the cross plate 24 scratching the steel section when clamping the steel section.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
