Description

Technical Field

[0001] The present invention relates to large equipment on an orbit, and particularly to a load 180-degree flipper. Background Art

[0002] After the load is produced, it is necessary to open the mold and remove all the embedded bolts on the load. After the load is mold-opened, the embedded bolts on it are buckled under the load, and the load needs to be flipped over to remove the embedded bolts. Usually, a crane is used to lift the load for flipping. Since the weight of the load is generally 5 to 30 tons, when the load is lifted and flipped by a crane, the load is prone to breakage.

[0003] For this reason, Dalian Tiger Metal Products Co., Ltd. discloses a load 180-degree flipper in 200910220589.5, which includes a base, a large support, a small support, and a support rod. The large support, the small support, and the support rod are respectively arranged on the base. The base is also provided with a feeding device and a hydraulic cylinder. The feeding device is connected to the top end of the large support, and the hydraulic cylinder is connected to the bottom end of the large support. Using the load 180-degree flipper to flip the load is convenient in operation and simple in structure.

[0004] However, when the load 180-degree flipper weighs up to 30 tons, the large support, the small support, and the support rod are arranged on the base. The feeding device is a feeding plate and a receiving plate, and the feeding plate and the receiving plate are connected to the top end of the large support. The load is placed on the feeding plate. The above structural arrangement simply cannot bear the weight of a 30-ton load and is extremely prone to breakage during the entire flipping process, and it does not have practical operability. Moreover, the existing mechanical transmission simply cannot be applied to the transmission of a load of such weight, and there is great insecurity during the entire load flipping process. Summary of the Invention

[0005] The present invention provides a load 180-degree flipper to achieve a load 180-degree flipper that rotates safely by 180 degrees.

[0006] A load 180-degree flipper includes a frame, a 90° flipping assembly, a 180° flipping assembly, a first lifting device, and a second lifting device. The 90° flipping assembly includes a first rotatable support and a first support platform. The 180° flipping assembly includes a second rotatable support and a second support platform, wherein:

[0007] The first rotatable support and the second rotatable support are respectively arranged on the frame; the first support platform and the second support platform are respectively rotatably arranged on the frame through the first rotatable support and the second rotatable support;

[0008] The first support platform of the 90° flipping assembly rotates between 0° - 90° and 90° - 0° under the control of the first jacking device; the second support platform of the 180° flipping assembly rotates between 90° - 180° and 180° - 90° under the control of the second jacking device, and when the 90° flipping assembly and the 180° flipping assembly are both in a state perpendicular to the plane at 90°, the space between the first support platform and the second support platform can accommodate the load.

[0009] Before placing the load, first flip the 180° flipping assembly of the flipping machine to 90°, place the load flat on the 180° flipping assembly and flip it by 90°. The load is just placed on the baffle of the 180° flipping assembly, and then flip the 180° flipping assembly back. After two 90° flips, the front side can be flipped to the back side.

[0010] Compared with the prior art, the present invention has the following advantages: Before placing the load, the 90° flipping assembly and the 180° flipping assembly are in a horizontal state. First, flip the 180° flipping assembly of the flipping machine to 90°, place the load flat on the 90° flipping assembly and flip it from the horizontal state to the vertical state. The bracket of the 180° flipping assembly takes over and flips the load to the horizontal state. Especially when the load is a track slab, when the maximum length of the 180-degree flipping machine itself is 2919 mm, the width is 5935 mm, and the height is 1602 mm, the implementation scheme is simple, and it can be used for flipping plates with a weight of 20 tons. Most importantly, the operation is simple and safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 is the partial structure diagram of the 180-degree flipping machine for the load;

[0013] Figure 3 is the schematic diagram of the frame. DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention will be specifically described below with reference to the accompanying drawings.

[0015] Please refer to Figures 1 to 3 , a 180-degree flipping machine for a load, including a frame 1, a 90° flipping assembly 2, a 180° flipping assembly 3, a first jacking device, a second jacking device. The 90° flipping assembly includes a first rotatable support 12 and a first support platform 11. The 180° flipping assembly includes a second rotatable support and a second support platform (the components of the 90° flipping assembly and the 180° flipping assembly are basically the same, and no additional drawing will be made). Among them:

[0016] The first rotatable support 12 and the second rotatable support are respectively arranged on the frame 1. Considering the weight, generally, they are evenly arranged on both sides of the frame. In this example, the cross-section of the frame 1 is rectangular, and the first rotatable support 12 and the second rotatable support are arranged on both sides of the middle part of the frame 1. The first support platform 11 and the second support platform are respectively rotatably arranged on the frame through the first rotatable support and the second rotatable support.

[0017] The first support platform 11 is mainly welded by a 250x150x10 rectangular pipe and a 15 steel plate, and is equipped with a backing plate (PA6 wear-resistant and anti-aging) and square timbers on it. The first support platform 11 includes a number of square timbers and a number of bearing plates 14. The square timbers play the function of bearing loads (such as track plates), and the square timbers are supported by the backing plates 13 arranged on the frame below. When bearing loads in the horizontal direction, the bearing plates 14 play the role of restricting the position of the loads in the horizontal direction. When the 90° flipping assembly 2 flips the loads to the vertical direction, the bearing plates 14 also play the role of bearing the loads at the bottom.

[0018] The second support platform also has a bearing plate 32. The load is placed on the 90° flipping assembly and flipped from the horizontal state to the vertical state. The brackets of the 180° flipping assembly (i.e., the brackets composed of the bearing plates 32) and the bearing plates 14 of the first support platform 11 are staggered at the bottom of the load. The brackets of the 180° flipping assembly can relay to flip the load to the horizontal state.

[0019] The frame 1 is welded by channel steel and a number of rectangular square pipes, and includes a main frame 21 and a number of sub-brackets. The main frame 21 is a rectangular frame welded by channel steel. And support frames 26 and 27 are respectively arranged in the middle parts of the two cross frames. The support frames 26 and 27 are higher than the main frame 21, making it possible to place the first jacking device and the second jacking device.

[0020] A middle cross beam 28 parallel to the vertical frames of the main frame 21 is arranged on the support frames 26 and 27. The middle cross beam 28 is located in the middle of the entire main frame 21 and provides support for the subsequent flipping of the load. Therefore, the middle cross beam 28 is made of channel steel and has a strong supporting effect. And a number of cushion blocks 281 are arranged on the middle cross beam 28. These cushion blocks 281 not only support the load, but more importantly, during the flipping process of the load, the load is flipped from the 90° flipping assembly 2 to the 180° flipping assembly 3, improving the easiness of flipping. Limit blocks 282 are respectively arranged on both side surfaces of the middle cross beam 28 to respectively limit the flipping angles of the 90° flipping assembly and the 180° flipping assembly 3.

[0021] The support frames 26 and 27 are provided with second rotating shaft mounting seats 291 and 292. The rotating shafts of the second rotatable supports of the 180° flipping assembly 3 are mounted on the second rotating shaft mounting seats 291 and 292.

[0022] The auxiliary support includes a first auxiliary support 22, a second auxiliary support 23, a third auxiliary support 24, and a fourth auxiliary support 25. The first auxiliary support 22 and the fourth auxiliary support 25 are parallel to the middle cross beam 28 and are respectively located on both sides of the middle cross beam 28, and are connected to the two cross frames of the frame. The second auxiliary support 23 and the third auxiliary support 24 are respectively parallel to the two cross frames of the frame and are connected to the first auxiliary support 22 and the fourth auxiliary support 25. The auxiliary support is arranged inside the main frame, which not only plays a good role in supporting the weight but also plays a role in balancing the weight. In particular, the connection ends 312 and 314 of the oil cylinder support of the 180° flipping assembly 3 can be arranged on the fourth auxiliary support 25, and the connection ends 311 and 313 of the oil cylinder support of the 90° flipping assembly 2 can be arranged on the first auxiliary support 22. This not only can play a good fixing role but also achieves force balance between the 180° flipping assembly and the 90° flipping assembly. Especially when the load flips it, taking the 180° flipping assembly as an example, the force of the load is located on the support frames 26 and 27, and the connection ends 312 and 314 of the oil cylinder support of the 180° flipping assembly 3 can be arranged on the fourth auxiliary support 25, and the force of its oil cylinder support is also balanced on the fourth auxiliary support 25, which can just balance the force located on the middle cross beam 28, and well achieve the effect of force balance and improve the overall safety. The second support frame 33 and the third support frame 34 are respectively arranged on the second auxiliary support 23 and the third auxiliary support 24, and the first rotating shaft mounting seats 331 and 332 are respectively arranged on the second support frame 33 and the third support frame 34. The rotating shaft of the first rotatable support of the 90° flipping assembly 2 is installed on the first rotating shaft mounting seats 331 and 332. The first rotating shaft mounting seat and the second rotating shaft mounting seat are located on different cross frames, which not only decomposes the acting force but also makes the force located on different cross frames, improves the force on different cross frames, reduces the material requirements for the cross frames, and also improves the safety. Multiple mounting platforms can be arranged on the auxiliary support to place the electric control box and the like. The frame 1 is integrally fixed to the workshop floor.

[0023] The first support platform of the 90° flipping assembly rotates at 0° - 90° and 90° - 0° under the control of the first jacking device; the second support platform of the 180° flipping assembly rotates at 90° - 180° and 180° - 90° under the control of the second jacking device, and when the 90° flipping assembly and the 180° flipping assembly are both in the state perpendicular to the 90° plane, the space between the first support platform and the second support platform can accommodate the load.

[0024] Before placing the load, the 90° flipping assembly and the 180° flipping assembly are in a horizontal state. First, flip the 180° flipping assembly of the flipping machine to 90°. Place the load flat on the 90° flipping assembly and flip it from the horizontal state to the vertical state. The bracket of the 180° flipping assembly takes over to flip the load to the horizontal state. After two 90° flips, the front side can be flipped to the back side.

[0025] The first support platform and the second support platform are rotatably arranged on the frame through the first rotatable support and the second rotatable support respectively. The first support platform and the second support platform are mainly welded by 250x150x10 rectangular tubes and 15 steel plates, and are equipped with backing plates (PA6 wear-resistant and anti-aging) and square timbers on them.

[0026] The first lifting device and the second lifting device respectively include a number of flipping oil cylinders, a hydraulic station and an electric control. A number of flipping oil cylinders are connected to the hydraulic station, and the electric control is connected to the hydraulic station. And the cylinder supports for placing the flipping oil cylinders are arranged inside the main frame of the frame 1, and these cylinder supports are evenly arranged under the 90° flipping assembly and the 180° flipping assembly. The hydraulic station adopts a fully enclosed hydraulic system, with double hydraulic cylinders for flipping. The size of the hydraulic circuit oil tank, hydraulic pump, solenoid valve, hydraulic pipeline and oil cylinder should ensure a specified safety factor, and the safety factor is 2; the flipping process is stable, with a balance valve, and the oil cylinder can stop at any stroke position without retracting by itself; the power supply is AC380V / 50HZ, and the control circuit needs to have a motor phase loss and phase error protection device. The speed of the actuator is adjustable, with an H-type electromagnetic directional valve plus a hydraulic lock, and the system unloads in the neutral state, and the actuator maintains pressure; the oil suction and return filters ensure the cleanliness of the working medium; the pressure-adjustable balance valve ensures the stable control of the hydraulic system when the load descends; when the hydraulic cylinder extends, a counterbalance valve is added to the return oil pipeline.

[0027] A middle cross beam is also arranged in the middle of the frame 1, and vertical limit devices are respectively arranged on the left and right sides of the middle cross beam. The 90° flipping assembly and the 180° flipping assembly respectively reach the vertical angle limit through the limit devices.

[0028] Horizontal limit devices are respectively arranged on the main frame of the frame 1. The 90° flipping assembly and the 180° flipping assembly respectively reach the horizontal limit through the limit devices.

[0029] The first rotatable support and the second rotatable support adopt pedestal bearings.

[0030] The baffles of the 90° flipping assembly and the 180° flipping assembly should be larger than two-thirds of the area of the load, so as to ensure safety.

[0031] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
