Technical Field
[0001] The present application relates to the field of flipping equipment, and in particular to a vertical flipping device for heavy ice-making equipment. Background Art
[0002] During the transportation process of the ice-making equipment, it needs to be transferred by the transfer vehicle to a large lifting device (such as a gantry crane), and then the large lifting device will lift the ice-making equipment into place. Since the ice-making equipment is usually placed horizontally during transportation by the transfer vehicle, after the subsequent transfer vehicle transports the ice-making equipment to the large lifting device, it is necessary to first use a special flipping device to flip the horizontal ice-making equipment to a vertical state so that the ice-making equipment can stand up, and then the upright ice-making equipment is lifted into place by the large lifting device.
[0003] Related technologies, such as patent number CN103754805B, discloses a flipping device and flipping method for heavy equipment in a nuclear power plant. The flipping device includes a flipping frame (bracket) and a base (flipping bracket). One end of the flipping frame is rotatably connected to the base. When using the above-mentioned flipping device to flip the equipment, the equipment is first tied to the flipping frame, and then the upper end of the equipment is connected to the sling. The upper end of the equipment is lifted by the sling so that the equipment can be flipped through the flipping frame until the equipment is flipped to a vertical state.
[0004] With respect to the above-mentioned related technologies, when the above-mentioned flipping device is used to flip the equipment, when the hoist fails and causes the equipment to lose lifting traction, the equipment and the flipping frame will swing downward out of control and eventually fall to the ground, causing damage to the flipping device and the equipment. The overall safety and stability are relatively insufficient. Therefore, there is room for improvement. Utility Model Content

When it is necessary to reset the flip frame from the vertical state to the horizontal state later, first slide the slider toward the direction close to the base so that the slider drives the limit plate to disengage from the limit groove on the limit rod, and then swing the limit plate to make the end of the limit plate away from the slider disengage from the limit rod, so as to restore the slider to slide in the direction away from the base, so as to facilitate the subsequent swinging of the flip frame downward to the horizontal state.
[0011] Preferably, the limiting rail has a rail groove, both ends of the rail groove of the limiting rail are vertically connected with stoppers, and buffer springs are arranged on opposite sides of the stoppers at both ends of the rail groove, and the buffer springs are arranged opposite to the slider.

[0013] Preferably, the buffer spring is sleeved on the limiting track.
[0014] By adopting the above technical solution, by sleeve-arranging the buffer spring on the outer periphery of the limiting track, the buffer spring can be limited by the limiting track, so that the buffer spring can be better extended and retracted along its own axial direction.

[0020] By adopting the above technical solution, while limiting the slider through the snap-in wheel, the friction between the slider and the limiting track can be reduced through the snap-in wheel, making it easier for the slider to slide along the limiting track more smoothly.

Subsequently, when the sling is connected to the upper end of the ice-making device and the upper end of the ice-making device is lifted by the sling, the ice-making device can drive the supporting frame to swing together with the ice-making device through the clamping frame, thereby realizing the flipping of the ice-making device.
[0023] Preferably, a plurality of support blocks are further provided on one side of the base, and when the support frame is flipped to a horizontal state, one end of the support frame away from the base overlaps the support block.
[0024] By adopting the above technical solution, the support frame is assisted by the support blocks, which is helpful to improve the overall stability of the support frame, so that the subsequent ice-making equipment can be placed on the support frame more stably.

[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] The present application embodiment discloses a vertical flip device for heavy ice making equipment, referring to Figure 1 and Figure 2, including a base 1, a flip frame 2 and a limit assembly; one end of the flip frame 2 is horizontally rotatably connected to the top of the base 1; the limit assembly includes two sets of limit rails 3 horizontally arranged on one side of the base 1, the length direction of the limit rails 3 is perpendicular to the rotation axis of the flip frame 2, and a slider 4 is slidably connected to the limit rails 3. A connecting rod 40 is arranged between the slider 4 and the flip frame 2, and both ends of the connecting rod 40 are horizontally rotatably connected to the slider 4 and the flip frame 2, and the rotation axis at both ends of the connecting rod 40 is arranged parallel to the rotation axis of the flip frame 2; a limit rod 5 is arranged in parallel on one side of the limit rail 3, and a plurality of limit grooves are uniformly arranged on the limit rod 5 along the length direction, and a limit plate 51 is arranged on one side of the slider 4, one end of the limit plate 51 is horizontally rotatably connected to the slider 4, and the other end of the limit plate 51 extends downwardly in a direction away from the base 1 and is inserted into the limit groove on the limit rod 5.
[0037] The base 1, the limiting rail 3 and the limiting rod 5 are all fixed to the ground, and specifically, they can be fixedly connected to the ground by means of anchor bolts or embedded parts. In the embodiment of the present application, the limiting rod 5 is a rack; the limiting groove is an inter-tooth groove on the rack, and the limiting piece 51 is a pawl, and the pawl end of the pawl is inserted into the inter-tooth groove on the rack.
[0038] When the flip frame 2 flips from the horizontal state to the vertical state, the flip frame 2 drives the slider 4 to slide from the end of the limiting track 3 away from the base 1 to the end of the limiting track 3 close to the base 1 through the connecting rod 40. During the movement of the slider 4, the limiting piece 51 is driven to slide along the limiting rod 5. When the flip frame 2 stops flipping during the flipping process, the limiting piece 51 is automatically inserted into the limiting groove on the limiting rod 5 to limit the slider 4 from sliding toward the end of the limiting track 3 away from the base 1, so as to fix the position of the slider 4, so that the slider 4 can temporarily support and fix the flip frame 2 through the connecting rod 40 to limit the flip frame 2 from swinging downward. When it is necessary to swing the flip frame 2 from the vertical state to the horizontal state, first slide the slider 4 from the direction close to the base 1 to make the end of the limiting piece 51 disengage from the limiting groove, and then swing the limiting piece 51 to make the end of the limiting piece 51 away from the limiting rod 5, so that the slider 4 can slide in the direction away from the base 1, thereby facilitating the flip frame 2 in the vertical state to swing downward to the horizontal state.
[0039] Reference Figure 1 and Figure 3 The flip frame 2 includes a support frame 21, one end of the support frame 21 is connected to a plurality of first ear plates, the top of the base 1 is connected to a plurality of second ear plates, the plurality of first ear plates correspond to the plurality of second ear plates one by one, and the first ear plates and the corresponding second ear plates are hingedly connected through a pin shaft to realize the horizontal rotation of the flip frame 2 connected to the base 1.
[0040] The end of the support frame 21 close to the base 1 is also vertically connected to the limiting frame 22. When the support frame 21 is flipped to a vertical state, the support frame 21 and the limiting frame 22 are in an "L" shape. Through the above arrangement, before flipping the ice-making device, the flip frame 2 is flipped until the support frame 21 is horizontal; when flipping the ice-making device, the ice-making device to be flipped is placed on the support frame 21 and the lower end of the ice-making device is abutted against the limiting frame 22. When the upper end of the ice-making device is subsequently lifted by a sling, the ice-making device can drive the flip frame 2 to flip through the limiting frame 2, so that the ice-making device can be flipped through the flip frame 2.
[0041] Reference Figure 2 and Figure 4 , two sets of limiting rails 3 are respectively located at the two ends of the side of the base 1. The limiting rail 3 has a rail groove 30, and the two opposite sides of the rail groove 30 are both concavely provided with a clamping groove 301, and the bottom of the slider 4 is connected to a connecting block 41, and the two opposite sides of the connecting block 41 are both convexly provided with a clamping part, and the clamping part includes a plurality of clamping wheels 42 connected to the side of the connecting block 41 in a horizontal rotation, and the rotation axis of the clamping wheel 42 is arranged parallel to the rotation axis of the flip frame 2. The clamping wheels 42 on the opposite sides of the connecting block 41 are respectively located in the clamping grooves 301 on the opposite sides of the rail groove 30, and the bottom of the connecting block 41 is spaced from the rail groove 30, and the outer periphery of the bottom of the clamping wheel 42 abuts against the rail groove 30. Through the above arrangement, the slider 4 is slidably connected to the limiting rail 3. Through the arrangement of the clamping wheels 42 on both sides of the connecting block 41, on the one hand, the slider 4 can be restricted from being separated from the limiting rail 3, and on the other hand, the friction between the slider 4 and the rail groove 30 can be reduced, so that the slider 4 can slide more smoothly and stably on the limiting rail 3.
[0042] The slider 4 is connected to a third ear plate, the side of the support frame 21 is connected to a fourth ear plate, and both ends of the connecting rod 40 are hinged to the third ear plate and the fourth ear plate through a pin shaft, so that the two ends of the connecting rod 40 are rotatably connected to the slider 4 and the flip frame 2 respectively.
[0043] Reference Figure 1 and Figure 2 , blocks 31 are vertically fixed at both ends of the track groove 30, and buffer springs 32 are connected to the opposite sides of the blocks 31 at both ends of the track groove 30, and the length direction of the buffer spring 32 is parallel to the length direction of the track groove 30. The buffer spring 32 is arranged opposite to the slider 4. Through the above arrangement, when the slider 4 slides to the end of the limiting track 3 close to the base 1 or the end of the limiting track 3 away from the base 1, the buffer springs 32 at both ends of the limiting track 3 can buffer the slider 4 to reduce the speed of the flip frame 2 flipping to the vertical state or the horizontal state, so that the ice-making device can be flipped more smoothly through the flip frame 2.
[0044] In this embodiment, the buffer spring 32 is sleeved on the outer periphery of the limiting track 3 to limit the buffer spring 32 through the limiting track 3, so that the buffer spring 32 can better extend and retract along its own axis. The limiting track 3 is fixed with a plurality of pads, which are used to support the limiting track 3 and the buffer spring 32 off the ground so that the buffer spring 32 does not interfere with the ground.
[0045] Reference Figure 5 In other embodiments, the spring may also be embedded in the track groove 30 , and the track groove 30 is used to limit and guide the buffer spring 32 .
[0046] Two groups of support blocks 6 are also vertically arranged on one side of the base 1. The support blocks 6 are fixed to the ground, and specifically, can be fixedly connected to the ground by means of anchor bolts or embedded parts. The two groups of support blocks 6 are located between the two groups of limit rails 3. When the support frame 21 is flipped to a horizontal state, the end of the support frame 21 away from the base 1 abuts against the top of the two groups of support blocks 6, so that the support frame 21 in a horizontal state is assisted by the two groups of support blocks 6, which is conducive to improving the stability of the support frame 21 in a horizontal state, and is convenient for the support frame 21 to support the ice-making equipment more stably.
[0047] The implementation principle of the embodiment of the present application is: before turning over the ice-making device, the limiting piece 51 is swung to make the end of the limiting piece 51 away from the slider 4 detach from the surface of the limiting rod 5, and the support frame 21 is turned over to a horizontal state.
[0048] When flipping the ice-making device, place the ice-making device to be flipped on the support frame 21 and make the lower end of the ice-making device abut against the limit frame 22, connect the upper end of the ice-making device to the hook of the sling, and lift the upper end of the ice-making device through the sling so that the ice-making device can be flipped to a vertical state through the flip frame 2.
[0049] By setting the limit assembly, when the support frame 21 swings from the horizontal state to the vertical state, the slider 4 on the limit track 3 moves toward the direction close to the base 1 under the drive of the connecting rod 40. When the ice-making equipment is flipped through the flip frame 2 and the sling fails and causes the ice-making equipment to lose the lifting traction force, the limit plate 51 is automatically inserted into the limit groove of the limit rod 5 to limit the slider 4 from sliding in the direction away from the base 1, thereby limiting the support frame 21 and the ice-making equipment on the support frame 21 from swinging downward, thereby achieving temporary fixation of the support frame 21 and the ice-making equipment, reducing the situation where the support frame 21 and the ice-making equipment lose control and fall to the ground, which is beneficial to improving the safety and stability of the flipping device.
[0050] 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.
