Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to a gantry crane for hoisting steel frame components. Background Art

[0002] Gantry crane is a kind of lifting equipment widely used in the industrial field. It has remarkable structural characteristics. It usually has a gantry-like frame, which consists of two legs and a main beam across the top. This structural design makes the gantry crane have high stability and load-bearing capacity. The application scenarios of gantry crane are very diverse. In ports, it is used to load and unload large goods, such as containers; in construction sites, it can lift building materials and prefabricated components; in factory workshops, it can carry heavy machinery parts, etc. It has many advantages, such as strong lifting capacity, which can lift extremely heavy objects; wide working range, can cover a large area, and gantry cranes are usually used for batch handling of steel frame components;

[0003] When existing gantry cranes are lifting and transporting batches of steel frame components, they will continue to shake due to external forces such as wind, causing the hoisted steel frame components to gradually tilt or move. When a batch of steel frame components are tilted or moved due to the shaking force, they are very likely to slide out from the side and fall, causing safety hazards. Therefore, we propose a gantry crane for lifting steel frame components. Summary of the invention

[0010] Wherein, the hoisting device comprises:

[0011] A hydraulic push rod, one end of which is provided with a square sleeve plate;

[0012] The circular concave shell is used to cover and resist the two ends of the hoisted steel frame members. By arranging the circular concave shells on both sides of the steel frame members to cover and resist the two ends, it is prevented that a batch of steel frame members are tilted or moved by the shaking force and are likely to slide out from the side and fall, causing safety hazards. The circular concave shell can be pushed by the hydraulic push rod to cover and resist steel frame members of different lengths, and the circular concave shell is difficult to adapt and resist when the steel frame members exceed a certain length on both sides of the top long plate.

[0018] One end of the limiting long rod away from the arc-shaped connecting rod passes through the square sleeve plate and is fixedly connected to the square sleeve plate. Three semicircular rods are provided, and the three semicircular rods are evenly distributed at the bottom of the top long plate.

[0019] Furthermore, the protective mechanism includes a hollow air cushion, which is elastically contacted by arranging a hollow air cushion of elastic material between the steel frame member and the inner wall of the circular concave shell to prevent the steel frame member from causing certain damage to the circular concave shell after colliding with the inner wall of the circular concave shell for a long time, resulting in a shorter service life of the circular concave shell. A corrugated disc is fixedly connected to the side of the hollow air cushion away from the circular concave shell, and a corrugated disc is arranged between the hollow air cushion and the steel frame member to make the steel frame member and the hollow air cushion indirectly contact with each other, so as to prevent the hollow air cushion from being easily damaged and difficult to use due to the long-term friction contact between the two ends of some steel frame members, and an exhaust circular hole is opened on the side of the hollow air cushion close to the corrugated disc. When the hollow air cushion is squeezed, the internal gas is discharged to the corrugated disc and the hollow air cushion through the exhaust circular hole. Between the outer sides of the hollow air cushion, to prevent the hollow air cushion from being subjected to excessive extrusion pressure for a long time, the internal gas is squeezed to nowhere to go, causing the hollow air cushion to explode and be damaged. The inner wall of the hollow air cushion is fixedly connected with an extension spring, and the extension spring pushes the hollow air cushion to expand and recover through the extension force, to prevent the hollow air cushion from being subjected to excessive extrusion pressure for a long time, causing its material to deform and be difficult to recover to the initial state. The side of the hollow air cushion away from the corrugated disc is fixedly connected to the inner side of the circular concave shell, and the outer side of the corrugated disc is fixedly connected to the inner side of the circular concave shell.

When the arc-shaped rotating rod rotates to the inside completely facing outward, the batches of steel frame members on the inside slide out along the arc surface of the arc-shaped rotating rod due to gravity for unloading, thereby preventing the batches of steel frame members from being difficult to unload manually, which is time-consuming and labor-intensive and also causes safety hazards to the staff.

[0023] 2. The present invention provides a lifting device and a plurality of semicircular rods at the bottom of the top long plate to lift steel frame members of different lengths, so as to prevent some steel frame members from being too short to be inserted into the circular concave shell and tilting and sliding out due to the shaking force during transportation, thereby causing safety hazards; circular concave shells are provided on both sides of the steel frame members to cover and resist both ends thereof, so as to prevent batches of steel frame members from tilting due to the shaking force or sliding out from the side and falling when moving, thereby causing safety hazards; when the circular concave shell moves, a limiting long rod running through one side limits the sliding of the circular concave shell, so as to prevent the inserted steel frame member in the circular concave shell from becoming unstable due to the influence of gravity when its weight gradually increases; the circular concave shell is pushed to move by the hydraulic push rod, so as to cover and resist steel frame members of different lengths, so as to prevent the circular concave shell from being difficult to adapt and resist when the steel frame member exceeds a certain length on both sides of the top long plate.

A corrugated disc is set between the hollow air cushion and the steel frame member to make the steel frame member and the hollow air cushion indirectly contact, so as to prevent the sharp ends of some steel frame members from being easily damaged and difficult to use after friction contact with the hollow air cushion for a long time, and when the hollow air cushion is squeezed, the internal gas is discharged to between the corrugated disc and the outer side of the hollow air cushion through the exhaust circular hole, so as to prevent the internal gas from being squeezed to nowhere to go when the hollow air cushion is subjected to excessive extrusion pressure for a long time, resulting in explosion and damage of the hollow air cushion, and the extension spring pushes the hollow air cushion to expand and recover through the extension force, so as to prevent the hollow air cushion from being subjected to excessive extrusion pressure for a long time, resulting in deformation of its material and difficulty in recovering to its initial state.

[0025] 4. The present invention sets a discharge mechanism. When the arc-shaped rotating rod rotates to the inside and faces completely outward, the batch of steel frame components inside slide out along the arc surface of the arc-shaped rotating rod under gravity for discharge, which prevents the batch of steel frame components from being difficult to be discharged manually, which is time-consuming and labor-intensive, and also causes safety hazards to the staff.

[0052] The unloading mechanism 709 comprises a rectangular base frame 7091, both sides of the rectangular base frame 7091 are provided with T-shaped slide grooves 7092, the inner wall of the T-shaped slide groove 7092 is slidably connected with a T-shaped long rod 7093, both sides of the T-shaped long rod 7093 are fixedly connected with a vertical bent plate 7094, one side of the vertical bent plate 7094 is penetrated and rotatably connected with a long through rod 7095, the outer side of the long through rod 7095 is fixedly connected with an external push plate 7096, one end of the long through rod 7095 is fixedly connected with a driving shaft of a motor 7097, one side of the vertical bent plate 7094 is rotatably connected with an arc-shaped rotating rod 7098 through a rotating bolt, the bottom of the arc-shaped rotating rod 7098 is fixedly connected with a retraction spring 7099, and the bottom of the retraction spring 7099 is fixedly connected with a rectangular baffle 70 910, the top of the rectangular base frame 7091 is fixedly connected with a curved connecting plate 70911, the inner side of the curved connecting plate 70911 is fixedly connected with an electric push rod 70912, the driving shaft of the electric push rod 70912 is fixedly connected with a rectangular long plate 70913, a plurality of T-shaped slide grooves 7092 are provided, and the plurality of T-shaped slide grooves 7092 are respectively distributed on both sides of the rectangular base frame 7091, the bottom of the T-shaped long rod 7093 is fixedly connected to the top of the rectangular long plate 70913, the bottom of the vertical bending plate 7094 is fixedly connected to the top of the rectangular long plate 70913, the output end of the motor 7097 is fixedly connected to one side of the vertical bending plate 7094, the bottom of the rectangular baffle 70910 is fixedly connected to the top of the rectangular base frame 7091, and when in use, the circular concave When the shell 703 moves toward the top long plate 705 so that the steel frame member is inserted into the inner side of the circular concave shell 703, the steel frame member contacts the corrugated disc 7062 and pushes the corrugated disc 7062 to squeeze the hollow air cushion 7061. When the hollow air cushion 7061 is squeezed, the internal extension spring 7064 is compressed. The hollow air cushion 7061 made of elastic material is arranged between the steel frame member and the inner wall of the circular concave shell 703 for elastic contact. At the same time, the material of the corrugated disc 7062 is relatively wear-resistant.

When the hollow air cushion 7061 is squeezed, the gas inside is discharged to the corrugated disc 7064 through the exhaust circular hole 7063. 062 and the outer side of the hollow air cushion 7061, when the steel frame components are removed and no longer squeeze the hollow air cushion 7061, the extension spring 7064 pushes the hollow air cushion 7061 to expand and recover through the extension force. When unloading is required, the electric push rod 70912 pushes the rectangular long plate 70913 downward. When the rectangular long plate 70913 moves downward, it drives the top T-shaped long rod 7093 and the vertical bent plate 7094 to move downward together. When the T-shaped long rod 7093 moves downward, it slides in the T-shaped slide groove 7092. When the vertical bent plate 7094 moves downward, it drives the arc-shaped rotating rod 7098 to move downward together. At this time, the retraction spring 7099 is in a fully contracted state and is difficult to be compressed. When the arc-shaped rotating rod 7098 moves downward, it moves relative to the rectangular baffle 70910.The rectangular baffle 70910 pushes the downwardly moved arc-shaped rotating rod 7098 to rotate outward around the part of the vertical bent plate 7094 away from one end of the T-shaped long rod 7093. At this time, the arc-shaped bent rod pulls the retraction spring 7099 at the bottom to extend the arc path. When the arc-shaped bent rod rotates, it drives the batch of steel frame components on the inside to rotate outward together. When the arc-shaped rotating rod 7098 rotates to the inside completely facing outward, the batch of steel frame components on the inside slide out along the arc surface of the arc-shaped rotating rod 7098 under gravity for unloading. After unloading, if there is no need to load again, the rectangular long plate 70913 can be driven upward by the electric push rod 70912, so that the vertical bent plate 7094 drives the arc-shaped bent rod to move upward. When the arc-shaped bent rod moves upward, the retraction spring 7099 gradually retracts until the arc-shaped bent rod moves above the rectangular baffle 70910, and the retraction spring 7099 gradually retracts to its initial state. The arc-shaped rotating rod 7098 is pulled to rotate to a position where the top is aligned with the bottom of the semicircular rod 710. When the tops of the two arc-shaped rotating rods 7098 are respectively aligned with the bottom ends of the semicircular rod 710, the retraction spring 7099 is in a fully tightened state and is difficult to be further compressed. As the vertical bending rod moves upward, the arc-shaped rotating rod 7098 is continuously rotated inward by the pulling force of the retraction spring 7099. When the arc-shaped rotating rod 7098 rotates to the point where the center of gravity is located at the bottom, steel frame components and goods can be placed in the arc-shaped rotating rod 7098. When the goods placed in the arc-shaped rotating rod 7098 are large in weight, the motor 7097 can be started to drive the long through rod 7095 to rotate. The rotation of the long through rod 7095 drives the outer external push plate 7096 to rotate. The outer push plate 7096 rotates upward from the outside to contact the arc-shaped rotating rod 7098 and pushes the arc-shaped rotating rod 7098 to rotate inward.

[0053] When the present invention is in operation, the driving motor 4 is started to drive the roller 5 to rotate. When the roller 5 rotates, the steel rope hook lock 6 is released, so that the hoisting device 7 hooked by the lifting ring 8 moves down to the ground. At this time, a batch of steel frame components are placed in the hoisting device 7. After placement, the driving motor 4 is started to drive the roller 5 to reverse and reel in the steel rope hook lock 6, so that the hoisting device 7 moves up to a certain height, and then the hoisting device 7 is driven by the electric pulley 2 to move to the position where unloading is required, and then the line is released and the goods are automatically unloaded through the hoisting device 7. When the steel rope hook lock 6 is released, the lifting ring 8 and the hoisting device 7 move downward as a whole until the bottom of the unloading mechanism 709 falls on the ground and stops. At this time, the unloading mechanism 709 is opened to place a batch of steel frame components therein. Then, the unloading mechanism 709 cooperates with the semicircular rod 710 to form a circular ring area to surround the placed steel frame components. By setting a plurality of semicircular rods 710 at the bottom of the top long plate 705, the steel frame components of different lengths can be hoisted. After the steel frame components are placed, the hydraulic push rod 701 drives the top square plate 704 to move toward the top long plate 705. The movement of the top square plate 704 drives the bottom circular concave shell 703 to move. The circular concave shell 703 gradually moves toward the top long plate 705 so that the two ends of the steel frame component are inserted into the inner side of the circular concave shell 703. By setting the circular concave shell 703 on both sides of the steel frame component to cover its two ends, the two ends of the steel frame component will be connected with the protective mechanism 706 when inserted into the inner side of the circular concave shell 703. When the circular concave shell 703 moves, a limiting long rod 707 that passes through one side thereof slides and limits it. The circular concave shell 703 is pushed to move by the hydraulic push rod 701, so that steel frame components of different lengths can be covered and resisted. When the circular concave shell 703 moves toward the top long plate 705 so that the steel frame component is inserted into the inner side of the circular concave shell 703, the steel frame component contacts the corrugated disc 7062 and pushes the corrugated disc 7062 to squeeze the hollow air cushion 7061. When the hollow air cushion 7061 is squeezed, the internal extension spring 7064 is compressed. The hollow air cushion 7061 made of elastic material is arranged between the steel frame component and the inner wall of the circular concave shell 703 for elastic contact. At the same time, the material of the corrugated disc 7062 is made of a relatively wear-resistant material. A corrugated disc 7062 is arranged between the cushion 7061 and the steel frame member to make the steel frame member indirectly contact with the hollow air cushion 7061. When the hollow air cushion 7061 is squeezed, the gas inside is discharged to the space between the corrugated disc 7062 and the outer side of the hollow air cushion 7061 through the exhaust circular hole 7063. When the steel frame member is removed and no longer squeezes the hollow air cushion 7061, the extension spring 7064 pushes the hollow air cushion 7061 to expand and recover through the extension force. When unloading is required, the rectangular long plate 70913 is pushed downward by the electric push rod 70912. When the rectangular long plate 70913 moves downward, it drives the top T-shaped long rod 7093 and the vertical bent plate 7094 to move downward together. When the T-shaped long rod 7093 moves downward, it slides in the T-shaped slide groove 7092.When the vertical bending plate 7094 moves downward, the arc-shaped rotating rod 7098 is driven to move downward together. At this time, the retraction spring 7099 is in a fully contracted state and is difficult to be compressed. When the arc-shaped rotating rod 7098 moves downward, it is relatively displaced with the rectangular baffle 70910. The rectangular baffle 70910 pushes the arc-shaped rotating rod 7098 to rotate outward around the part of the vertical bending plate 7094 away from one end of the T-shaped long rod 7093. At this time, the arc-shaped bending rod pulls the retraction spring 7099 at the bottom to extend the arc path. When the arc-shaped bending rod rotates, the batch of steel frame components on the inside are driven to rotate outward together. When the arc-shaped rotating rod 7098 rotates to the inside completely facing outward, the batch of steel frame components on the inside slide out along the arc surface of the arc-shaped rotating rod 7098 under gravity for unloading. After unloading, if no more loading is needed, the electric push rod 70912 can be used to drive the rectangular long plate 70913 to move up, so that the vertical bending plate 7094 drives the arc-shaped bending rod to move up, and the retraction spring 7099 gradually retracts when the arc-shaped bending rod moves up. , until the arc-shaped bending rod moves to the top of the rectangular baffle 70910, the retraction spring 7099 gradually retracts to the initial state and pulls the arc-shaped rotating rod 7098 to rotate to a position where the top is aligned with the bottom of the semicircular rod 710. When the tops of the two arc-shaped rotating rods 7098 are respectively aligned with the bottom ends of the semicircular rod 710, the retraction spring 7099 is in a fully tightened state and is difficult to be further compressed. As the vertical bending rod moves upward, the arc-shaped rotating rod 7098 is continuously pulled by the retraction spring 7099. When the arc-shaped rotating rod 7098 rotates inwards and the center of gravity is at the bottom, the steel frame goods can be put into the arc-shaped rotating rod 7098. When the goods placed in the arc-shaped rotating rod 7098 are large and heavy, the motor 7097 can be started to drive the long through rod 7095 to rotate. The rotation of the long through rod 7095 drives the outer push plate 7096 to rotate. The outer push plate 7096 rotates upward from the outside to contact the arc-shaped rotating rod 7098 and push the arc-shaped rotating rod 7098 to rotate inwards.
