Description

Technical Field

[0001] The utility model relates to the field of intelligent manufacturing of equipment, in particular to a large hydraulic turnover working platform. Background Art

[0002] For machinery manufacturers, turning heavy steel plates over is not only a necessary step in the production process, such as machine tool processing and large steel structure installation, but also a necessary task to improve workshop space utilization and facilitate the rational and orderly storage of heavy steel plates. However, turning steel plates weighing several tons safely and efficiently is no easy task.

[0003] Typically, a crane—a lifting device—must be installed in the workshop, requiring two or more people to work together to flip the plate. One person uses the crane to slowly lower the hook and slowly hoist the plate using a wire rope. After hoisting the plate, it is suspended at an appropriate height. Another person then moves to the other side of the plate and places blocks or supports under the plate, either in the middle or at either end. The crane's position is then slowly adjusted to position the plate at the desired flipping angle. The plate is carefully flipped along the crane's forward direction, constantly monitoring and controlling the plate's tendency to tilt sideways. The crane's trolley is then used to pull the plate completely sideways, achieving the desired tilt and flip. This method is prone to causing the plate to slip as it falls, severely damaging the lifting equipment and wire rope. This is a typical example of tilted or oblique lifting, illegal operation, and a violation of lifting equipment operating procedures. This not only significantly damages the lifting equipment but also poses a significant risk to the operator's safety.

[0004] Another approach involves welding temporary lifting lugs on the edges of the steel plates to facilitate the insertion of lifting equipment's wire ropes. The plates to be flipped are then secured with chains or wire ropes to achieve the desired lift and flip. This method requires pre-welding and post-grinding, which damages the steel plates and consumes materials, labor, and time. It is also inefficient and difficult to operate. Furthermore, the plate must be repeatedly adjusted to prevent deformation, significantly impacting production efficiency.

[0005] Another method involves using a magnetic plate lifter to magnetically attract the plate. However, due to the plate's heavy weight, it's very easy for it to slip and become unhooked during the lifting process. Rust on the plate surface needs to be removed before lifting. Operators must maintain the plate's balance during the flipping process to avoid an unstable center of gravity that could lead to an awkward flip or accidents. This is a very labor-intensive process and poses safety risks.

[0006] The above methods of turning over heavy steel plates all have certain safety hazards during operation, which often lead to blood loss due to negligence. They pose a great threat to workshop production safety and personnel safety. Utility Model Content

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0029] The following will refer to the accompanying drawings and embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference below Figures 1 to 6 The large hydraulic turnover work platform of the utility model is described in conjunction with the embodiments.

[0031] like Figure 1 As shown, a large hydraulic tilting work platform comprises three parts: a base frame structure 1, a front tilting frame structure 2, and a rear tilting frame structure 3. All the frame structures are made of thick-walled load-bearing steel pipes welded together in multiple layers, with reinforcing ribs added at each welded joint.

[0032] The anchor frame structure 1 includes: an anchor reinforcement frame 101, a forward-folding left hinge pillar 102, a forward-folding right hinge pillar 103, a forward-folding left load-bearing pillar 104, a forward-folding right load-bearing pillar 105, a rearward-folding left hinge pillar 106, a rearward-folding right hinge pillar 107, a rearward-folding left load-bearing pillar 108, and a rearward-folding right load-bearing pillar 109.

[0033] The front flip frame structure 2 mainly includes: three front flip frame load-bearing bases 201, a front flip left supporting cylinder 205, and a front flip right supporting cylinder 206.

[0034] The rear flip frame structure 3 mainly includes: 4 rear flip frame load-bearing base supports 310, a rear flip left auxiliary mounting plate 301, a rear flip right auxiliary mounting plate 302, a rear flip left front auxiliary cylinder 303, a rear flip right front auxiliary cylinder 304, a rear flip left rear auxiliary cylinder 305, a rear flip right rear auxiliary cylinder 306, a rear flip left support cylinder 307, and a rear flip right support cylinder 308.

[0035] The bottom of the anchor frame structure 1 is equipped with multiple reinforced anchors, which are passed through multiple chemical anchor bolts to secure the anchor frame structure 1 to the ground. This serves to strengthen the anchor frame structure 1 against bidirectional or multidirectional lateral forces, ensuring safety and reliability when the large hydraulic tilting work platform is operating under load.

[0036] At the front and rear ends of the anchor frame structure 1, multiple cylinder mounting seats are reserved, on which the front flip left supporting cylinder 205, the front flip right supporting cylinder 206, the rear flip left supporting cylinder 307, and the rear flip right supporting cylinder 308 are respectively installed.

[0037] Three front-flip frame support brackets 201 are fixed to the front end of the upper portion of the front-flip frame structure 2. Hinge pin holders are located on the left and right sides of the lower front portion of the front-flip frame structure 2, connected to the left and right front-flip hinge struts 102 and 103, respectively, via high-strength hinge pins. Cylinder joint holders are located on the left and right sides of the lower middle portion of the front-flip frame structure 2, connected to the cylinder rods of the left and right front-flip support cylinders 205 and 206, respectively, via high-strength hinge pins. The extension and retraction of the cylinder rods of the left and right front-flip support cylinders 205 and 206 drive the front-flip frame structure 2 to rotate within a range of 120°, centered around the pin holes of the left and right front-flip hinge struts 102 and 103. When the front-flip frame structure 2 is in the 0° position, it rests squarely on the left and right front-flip support struts 104 and 105, respectively.

[0038] Four rear-flip frame support brackets 310 are secured to the front end of the upper portion of the rear-flip frame structure 3. Hinge pin holders are located on either side of the lower front end of the rear-flip frame structure 3, connecting to the left and right rear-flip hinge struts 106 and 107, respectively, via high-strength hinge pins. Cylinder joint holders are located on either side of the lower middle portion of the rear-flip frame structure 3, connecting to the cylinder rods of the left and right rear-flip support cylinders 307 and 308, respectively, via high-strength hinge pins. The extension and retraction of the cylinder rods of the left and right rear-flip support cylinders 307 and 308 drive the rear-flip frame structure 3 to rotate within a range of 120°, centered around the pin holes of the left and right rear-flip hinge struts 106 and 107. When the rear-flip frame structure 3 is in the 0° position, it rests squarely on the left and right rear-flip support struts 108 and 109, respectively.

[0039] The front three front flip frame load-bearing supports 201 on the front flip frame structure 2 and the front four rear flip frame load-bearing supports 310 on the rear flip frame structure 3 are staggered. When the front flip frame structure 2 and the rear flip frame structure 3 are both erected at 90 degrees, the front three front flip frame load-bearing supports 201 on the front flip frame structure 2 and the front four rear flip frame load-bearing supports 310 on the rear flip frame structure 3 intersect with each other to form a flat surface.

[0040] A left auxiliary mounting plate 301 and a right auxiliary mounting plate 302 are fixed beneath the rear flip frame structure 3. A left front auxiliary cylinder 303 and a left rear auxiliary cylinder 305 are mounted on the left auxiliary mounting plate 301. A right front auxiliary cylinder 304 and a right rear auxiliary cylinder 306 are mounted on the right auxiliary mounting plate 302.

[0041] The top ends of the cylinder rods of the rear-flip left front auxiliary oil cylinder 303 , the rear-flip right front auxiliary oil cylinder 304 , the rear-flip left rear auxiliary oil cylinder 305 , and the rear-flip right rear auxiliary oil cylinder 306 are equipped with electrically controlled magnetic suction heads.

[0042] like Figure 2 As shown, this is a static structural diagram of a large hydraulic turning work platform for waiting for materials.

[0043] The anchor frame structure 1 is fixed on the ground and is connected with the front flip left supporting oil cylinder 205, the front flip right supporting oil cylinder 206, the rear flip left supporting oil cylinder 307 and the rear flip right supporting oil cylinder 308 through the oil cylinder seat and the high-strength hinge pin.

[0044] The forward-flipping frame structure 2 is connected to the left and right forward-flipping hinge struts 102 and 103, respectively, via hinge pin holders and high-strength hinge pins. It is also connected to the cylinder rods of the left and right forward-flipping supporting cylinders 205 and 206, respectively, via cylinder joint holders and high-strength hinge pins. With the left and right forward-flipping supporting cylinders 205 and 206 retracted, the forward-flipping frame structure 2 rests flat on the left and right forward-flipping load-bearing struts 104 and 105.

[0045] The rear flip frame structure 3 is connected to the left and right rear flip hinge struts 106 and 107, respectively, via hinge pin holders and high-strength hinge pins. It is also connected to the cylinder rods of the left and right rear flip support cylinders 307 and 308, via cylinder joint holders and high-strength hinge pins. With the cylinder rods of the left and right rear flip support cylinders 307 and 308 retracted, the rear flip frame structure 3 rests flat on the left and right rear flip support struts 108 and 109.

[0046] The cylinder rods of the rear flip left front auxiliary cylinder 303, the rear flip right front auxiliary cylinder 304, the rear flip left rear auxiliary cylinder 305, and the rear flip right rear auxiliary cylinder 306 are retracted, and the electrically controlled magnetic suction heads installed on the top ends of the cylinder rods of all the auxiliary cylinders are in a power-off and demagnetized state.

[0047] This large hydraulic tilting platform is equipped with an external electrical cabinet and hydraulic pump station. The cabinet is equipped with a touch screen that allows users to input the thickness of the steel plate to be flipped, set the parameters of each hydraulic cylinder, adjust and limit the stroke of each hydraulic cylinder, and handle alarm information.

[0048] The external hydraulic pump station is equipped with a hydraulic pressure gauge, hydraulic relief valve, hydraulic reversing valve, hydraulic oil temperature sensor, hydraulic flow meter, and hydraulic pressure regulating valve to meet the different movement requirements of each cylinder.

[0049] like Figure 3 As shown, a schematic diagram of the loading action of a large hydraulic tilting work platform.

[0050] The front tilt frame structure 2 of this large hydraulic tilting work platform is in the 0° position, and the front tilt frame structure 2 rests on the front tilt left load-bearing pillar 104 and the front tilt right load-bearing pillar 105. The rear tilt frame structure 3 is in the 180° position, and the rear tilt frame structure 3 rests on the rear tilt left load-bearing pillar 108 and the rear tilt right load-bearing pillar 109.

[0051] The cylinder rods of all supporting cylinders and auxiliary cylinders are retracted, and the electrically controlled magnetic suction heads installed on the top ends of the cylinder rods of the auxiliary cylinders are in a power-off state.

[0052] The heavy steel plate 100 to be flipped is hoisted onto the front flip frame structure 2 by installing a lifting device in the workshop.

[0053] like Figure 4 As shown, a schematic diagram of the flipping action of a large hydraulic flip work platform.

[0054] After the external hydraulic pump station is activated, the rods of the forward left support cylinder 205, the forward right support cylinder 206, the rearward left support cylinder 307, and the rearward right support cylinder 308 slowly extend. This extension of the rods of the forward left support cylinder 205 and the forward right support cylinder 206 causes the forward frame structure 2 and the heavy steel plate 100 to be flipped to rotate gradually from 0° to 90°, centered around the pin holes of the forward left hinge struts 102 and the forward right hinge struts 103. At this time, the rods of the rearward left support cylinder 307 and the rearward right support cylinder 308 extend, causing the rearward frame structure 3 to rotate gradually from 180° to 90°, centered around the pin holes of the rearward left hinge struts 106 and the rearward right hinge struts 107. In actual production, the control program adjusts the rotation angle according to the thickness of the steel plate to be flipped, as input via the touch screen on the external electrical cabinet. The hydraulic cylinder stroke can also be adjusted finely through the touch screen on the external electrical cabinet.

[0055] like Figure 5 As shown, a schematic diagram of the turning action process of a large hydraulic turning work platform.

[0056] The front flip frame structure 2 is held at approximately 70-80 degrees, allowing the bottom of the heavy steel plate 100 to be flipped to rest on the three front flip frame load-bearing bases 201 of the front flip frame structure 2 due to gravity. The front flip left support cylinder 205 and the front flip right support cylinder 206 are suspended. At this time, the rear flip frame structure 3 is at approximately 100-110 degrees, and the rear flip left support cylinder 307 and the rear flip right support cylinder 308 continue to operate until the rear flip frame structure 3 is at 90 degrees, at which point the rear flip left support cylinder 307 and the rear flip right support cylinder 308 are suspended.

[0057] After the rear flip frame structure 3 is at 90 degrees, the front flip left supporting cylinder 205 and the front flip right supporting cylinder 206 are activated again, driving the front flip frame structure 2 and the heavy steel plate 100 to be flipped to 90 degrees, and the front flip left supporting cylinder 205 and the front flip right supporting cylinder 206 are suspended. At this time, the front flip frame structure 2 and the rear flip frame structure 3, sandwiching the heavy steel plate 100 to be flipped, are all in a 90-degree vertical state. The four rear flip frame load-bearing base supports 310 of the rear flip frame structure 3 and the three front flip frame load-bearing base supports 201 of the front flip frame structure 2 are interlaced to form a plane and maintain horizontality.

[0058] The cylinder rods of the left front auxiliary cylinder 303, the right front auxiliary cylinder 304, the left rear auxiliary cylinder 305 and the right rear auxiliary cylinder 306 are extended, and the electrically controlled magnetic suction heads installed on the top of the cylinder rods of each auxiliary cylinder are electrically excited to attract the heavy steel plate 100 to be flipped. The magnetic force of the magnetic suction heads is evenly distributed horizontally to prevent the heavy steel plate 100 to be flipped from slipping during movement and causing "slippage".

[0059] The stroke of each hydraulic cylinder can be adjusted and set based on the thickness of the steel plate to be flipped, as input from the touch screen on the external electrical cabinet. The system program defines the extension length of the cylinder rods of the rear-flip left front auxiliary cylinder 303, rear-flip right front auxiliary cylinder 304, rear-flip left rear auxiliary cylinder 305, and rear-flip right rear auxiliary cylinder 306.

[0060] The rods of the left and right rear tilt support cylinders 307 and 308 are slowly retracted, and the rear tilt frame structure 3 is gradually adjusted to about 110-120 degrees. At this time, the bottom of the heavy steel plate 100 to be flipped has completely rested on the four rear tilt frame load-bearing bases 310 of the rear tilt frame structure 3 due to the action of gravity.

[0061] After the four rear flip frame load-bearing supports 310 of the rear flip frame structure 3 are completely separated from the three front flip frame load-bearing supports 201 of the front flip frame structure 2, the cylinder rods of the front flip left support cylinder 205 and the front flip right support cylinder 206 begin to retract, driving the front flip frame structure 2 to gradually move toward 0°, centered around the pin holes of the front flip left hinge support 102 and the front flip right hinge support 103. The cylinder rods of the rear flip left support cylinder 307 and the rear flip right support cylinder 308 continue to slowly retract, driving the rear flip frame structure 3 and the heavy steel plate 100 to be flipped to gradually move toward 180°, centered around the pin holes of the rear flip left hinge support 106 and the rear flip right hinge support 107.

[0062] like Figure 6 As shown, this is a schematic diagram of the completion of the flipping action of a large hydraulic flip work platform.

[0063] The cylinder rods of the left front tilt supporting cylinder 205 and the right front tilt supporting cylinder 206 continue to retract until the front tilt frame structure 2 of the large hydraulic tilting work platform is at a 0° position and the front tilt frame structure 2 falls on the left front tilt supporting pillar 104 and the right front tilt supporting pillar 105, and the left front tilt supporting cylinder 205 and the right front tilt supporting cylinder 206 stop moving.

[0064] The rods of the rear flip left supporting cylinder 307 and the rear flip right supporting cylinder 308 continue to slowly retract. At this point, the heavy steel plate 100 to be flipped has been safely flipped over. The rear flip frame structure 3 of this large hydraulic tilting work platform is at a 180-degree angle, resting on the rear flip left load-bearing pillar 108 and the rear flip right load-bearing pillar 109. The rear flip left supporting cylinder 307 and the rear flip right supporting cylinder 308 then cease operation. The electrically controlled magnetic suction heads mounted on the tops of the auxiliary cylinder rods are de-energized and demagnetized, and the rods of the rear flip left front auxiliary cylinder 303, rear flip right front auxiliary cylinder 304, rear flip left rear auxiliary cylinder 305, and rear flip right rear auxiliary cylinder 306 retract.

[0065] By installing a lifting device in the workshop, the heavy steel plate 100 that has been safely turned over is lifted from the rear flip frame structure 3. The turning action of the heavy steel plate is completed smoothly.

[0066] The purpose of this utility model is to provide a large hydraulic turning work platform. Especially for the heavy steel plate processing in large casting equipment, large press equipment, and large extrusion equipment, it effectively solves the practical problems of high risk, high failure rate of lifting equipment, long manual maintenance time, and discontinuous workshop production during the turning process of heavy steel plates.

[0067] The specific operation process is as follows:

[0068] Select a suitable workshop site to fix this large hydraulic turning work platform. Before operating the hydraulic turning work platform to turn over the steel plate, you must check the anchor frame structure 1, the front turning frame structure 2, the rear turning frame structure 3 and the hydraulic cylinders to ensure that there are no obstacles in the installation of lifting equipment in the workshop and within the working range of the hydraulic turning work platform.

[0069] First, through the touch screen window on the external electrical cabinet, set the initialization parameters such as the cylinder stroke, the extension position of the cylinder rod, and set the alarm range for monitoring the hydraulic oil temperature.

[0070] The front tilt frame 2 of this large hydraulic tilting platform is at a 0° angle, and the rear tilt frame 3 is at a 180° angle. Using the crane installed in the workshop, the heavy steel plate to be flipped is hoisted and placed onto the front tilt frame 2 of the hydraulic tilting platform. After confirming the safety of personnel and equipment within the tilting area, the start button is pressed.

[0071] like Figure 4 Figure 5 As shown, the forward-flipping left and right supporting cylinders 205 and 206 drive the forward-flipping frame structure 2 and the heavy steel plate to be flipped through a range of 0° to 90°. The rearward-flipping left and right supporting cylinders 307 and 308 drive the frame structure 3, which supports the heavy steel plate to be flipped, through a range of 90° to 180°. During this operation, the system program controls the alternating movements of the supporting and auxiliary cylinders according to the programmed steps, and the electrically controlled magnetic suction heads mounted on the tops of the auxiliary cylinder rods cooperate with each other.

[0072] After the heavy steel plate is flipped over, the hydraulic cylinder rods retract to maintain pressure, and the electrically controlled magnetic suction heads installed on the top of the auxiliary cylinder rods lose power and demagnetize. The front flip frame structure 2 of this large hydraulic flip work platform is once again in the 0° position, and the rear flip frame structure 3 is once again in the 180° position. The lifting equipment installed in the workshop is used to lift the safely flipped steel plate from the rear flip frame structure 3, waiting for the next heavy steel plate to be flipped.

[0073] During the operation of this large hydraulic tilting work platform, the equipment program system controls the movement of each hydraulic cylinder, records the hydraulic cylinder stroke, and constantly monitors the hydraulic pressure to ensure that the monitored hydraulic pressure values ​​reach the set values ​​and there are no alarm signals during the equipment operation.

[0074] This utility model provides a large-scale hydraulic turning work platform structure equipped with an external hydraulic pump station, multiple hydraulic cylinders as actuators, and multiple detection switches and proximity switches. This allows for precise control of the hydraulic cylinder stroke, improving operational stability and enhancing equipment safety. Furthermore, electrically controlled magnetic suction heads are mounted on the tops of the cylinder rods of the four auxiliary hydraulic cylinders. These heads provide a uniform horizontal distribution of magnetic force, enabling the turning of steel plates sideways and also providing a plate balancing function. During the turning operation, these heads securely hold heavy steel plates, preventing them from slipping and facilitating control of their position during the turning process.

[0075] There are alternative solutions to the proposed technical solution, such as using other forms of hydraulic stations to replace the external hydraulic pump station. Using other forms of hydraulic cylinders to replace the rear flip left front auxiliary cylinder 303, rear flip right front auxiliary cylinder 304, rear flip left rear auxiliary cylinder 305, and rear flip right rear auxiliary cylinder 306. Using other large cylinder forms to replace the front flip left support cylinder 205, front flip right support cylinder 206, rear flip left support cylinder 307, and rear flip right support cylinder 308. Using other forms of structures to replace the anchor frame structure 1, front flip frame structure 2, and rear flip frame structure 3 are all within the scope of protection of this utility model.

[0076] Compared with the existing technology, the large hydraulic turnover work platform of the utility model has the following advantages:

[0077] The utility model can be applied to the turning over of heavy steel plates in production workshops, and is especially suitable for the mass production of heavy steel plates processed by large casting equipment, large pressing equipment, and large extrusion equipment. This large hydraulic turning work platform is simple and easy to operate, and can turn heavy steel plates 180° according to actual production needs. The hydraulic cylinder self-locking mode can be selected to allow the turned steel plate to hover at any angle to facilitate production needs. During the turning over of heavy steel plates, no human intervention is required, and accidents such as personal injury are fundamentally eliminated. No welding or polishing is required before turning over heavy steel plates, which improves the flatness of the steel plates, saves time for subsequent processing, improves work efficiency, and provides strong support for continuous and coherent production.
