Technical Field
[0001] The present invention relates to the field of skid-mounted equipment, and in particular to a skid-mounted flexible synthetic ammonia production device. Background Art
[0002] Skid-mounted means that a set of equipment is fixed on a chassis made of angle steel or I-beam, and a lifting device can be used for moving and positioning. Now, in order to facilitate the treatment of ammonia-containing wastewater at different locations, the wastewater-to-ammonia device is usually fixed on a skid-mounted platform so that workers can move the wastewater-to-ammonia device to any position for work.
[0003] For example, the invention patent with the application number CN202111646192.X discloses a skid base stability structure for facilitating the lifting of the skid base, including a main body mechanism, which includes a bottom frame, an inner support frame arranged inside the bottom frame, and main lifting lugs symmetrically arranged on both sides of the bottom frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with four supporting legs, nuts, gears and racks. When the U-shaped steel frame falls to the ground, the four supporting legs will move upward one after another. As the last limit plate cancels the limit on the energy storage disc, the energy storage disc rotates under the action of the torsion spring, thereby causing the L-shaped pushing frame to push the rack to move, causing the nut to move upward and press against the bottom end of the U-shaped steel frame, thereby locking the four supporting legs, so that the four supporting legs can automatically adjust according to the irregular ground and complete self-locking, which is conducive to keeping the U-shaped steel frame in a horizontal state and evenly distributing the stress of the pipelines in the equipment.
[0018] 2. The present invention provides a sliding groove and a sliding block. During use, if the ground sinks and causes the U-shaped steel frame to tilt, the adjusting nut can be rotated to rotate the screw rod.

[0019] 3. The present invention sets a first limiting rod and a second limiting rod. Before the U-shaped steel frame is transported, the first limiting rod is pulled to slide, so that the two third connecting pins move along the first transverse groove in the first T-shaped groove of the front and rear legs. Then, the first fixing block is fixed to the first fixing seat by bolts, and the first limiting rod is limited, thereby limiting the legs, so that the four legs cannot slide, thereby ensuring that the energy storage disc is always in the energy storage state during transportation.
[0020] 4. The present invention provides a first counterweight block and a second counterweight block. During the hoisting process, if the U-shaped steel frame tilts, the first limit rod or the second limit rod slides to lock the four legs, thereby avoiding the problem of incorrect release of the energy storage disc due to operational errors, resulting in incorrect locking of the legs and failure to level the U-shaped steel frame.

[0024] As Figures 1 to 9 shown, a skid-mounted flexible ammonia synthesis production device, characterized by comprising: A square frame 1, two support legs 2 are symmetrically and slidably connected to the bottom ends of both sides of the square frame 1, the top ends of the support legs 2 are fixedly connected with threaded rods 3, and the threaded rods 3 penetrate through the top end of the square frame 1 and are slidably connected with the square frame 1; Four nuts 4, the four nuts 4 are threadedly connected to the surface of the threaded rod 3, the outside of the nuts 4 is fixedly connected with gears 5, the side walls of the gears 5 are slidably connected with racks 6, and the racks 6 are slidably connected within the square frame 1; Four L-shaped pushing frames 7, the four L-shaped pushing frames 7 are slidably connected to the inner side walls of the square frame 1 corresponding to the positions of the four racks 6, and a first spring 8 is fixedly connected between the L-shaped pushing frames 7 and the racks 6; A pushing assembly, during the upward movement of the four support legs 2, the pushing assembly pushes the L-shaped pushing frames 7, so that the racks 6 drive the gears 5 to rotate, so that the gears 5 drive the nuts 4 to rotate synchronously, and under the action of threaded connection, the nuts 4 move upward, thereby locking the four support legs 2; Among them, a plurality of lifting lugs 105 are symmetrically and fixedly connected to the top end of the square frame 1; The push components include: Two U-shaped drive seats 9 are symmetrically slidably connected to the side walls of the U-shaped steel frame 1. The top and bottom ends of the U-shaped drive seats 9 are both provided with drive inclined slots 901. The ends of the two L-shaped push frames 7 on the same side are fixedly connected with first connecting pins 701. The first connecting pins 701 are slidably connected to the drive inclined slots 901 at the corresponding positions. The pushing mechanism is used to push the U-shaped driving seat 9 to move, so as to move the two L-shaped pushing frames 7 on the same side; The driving agencies include: The connecting frame 10 has two ends fixedly connected to the two side walls of the bottom end of the U-shaped steel frame 1; The energy storage disc 11 is rotatably connected to the bottom end of the U-shaped steel frame 1. The rotating shaft of the energy storage disc 11 is rotatably connected to the bottom end of the connecting frame 10. A torsion spring 12 is sleeved on the rotating shaft surface of the energy storage disc 11. The two ends of the torsion spring 12 are respectively fixedly connected to the energy storage disc 11 and the connecting frame 10. Four limiting holes 1101 are opened at the top of the energy storage disc 11; Four limiting plates 13, one end of each of the four limiting plates 13 is fixedly connected to the side wall of the support leg 2, and the other end is slidably inserted into the limiting hole 1101; Two L-shaped push seats 14 are symmetrically slidably connected to the side walls of the Chinese-shaped steel frame 1. The ends of the L-shaped push seats 14 are fixedly connected to the side walls of the U-shaped drive seat 9. A driving chute 1401 is opened at the bottom of the L-shaped push seat 14. Two second connecting pins 1102 are fixedly connected to the top array of the energy storage disc 11. The second connecting pins 1102 are slidably connected in the driving chute 1401. Specifically, in the prior art, when the skid-mounted base is placed on the ground using lifting equipment, if the ground is irregular, the skid-mounted base will contact the ground unevenly, causing the skid-mounted base to tilt slightly. Since the synthetic ammonia production equipment is complex to assemble and contains a large number of connecting pipelines, if the skid-mounted base is in a tilted state, it will cause uneven stress distribution in the pipelines in the equipment, which is prone to damage during long-term use. The present technical solution can solve the above problem. The specific operation is as follows: First, use a lifting device to hoist the U-shaped steel frame 1 horizontally to the ground so that the support legs 2 at the bottom of the U-shaped steel frame 1 are close to the ground; During the process of the outrigger 2 approaching the ground, one or several outriggers 2 will first come into contact with the high points on the ground. Under the extrusion of the ground, the outrigger 2 moves upward, causing the limit plate 13 to move upward and leave the limit hole 1101. Subsequently, the square frame 1 continues to move downward, enabling the remaining outriggers 2 to come into contact with the low points on the ground. Under the extrusion of the ground, the remaining outriggers 2 move upward. At this time, all four outriggers 2 are in full contact with the ground, causing the remaining limit plates 13 to move upward and leave the limit hole 1101, and finally canceling the limit on the energy storage disc 11; After all four limit plates 13 have left the limit hole 1101, under the action of the torsion spring 12, the energy storage disc 11 rotates, causing the second connecting pin 1102 to move along the driving chute 1401. Under the push of the second connecting pin 1102, the L-shaped pushing seat 14 moves, thereby causing the U-shaped driving seat 9 to move, enabling the L-shaped pushing frame 7 to move along the driving inclined chute 901. Under the drive of the driving inclined chute 901, the L-shaped pushing frame 7 pushes the rack 6 to move, causing the rack 6 to mesh with the gear 5. The gear 5 drives the nut 4 to rotate. Under the action of the threaded connection, the nut 4 moves upward and abuts against the inner bottom end of the square frame 1, thereby locking the four outriggers 2. At this time, the four outriggers 2 cannot move upward along the square frame 1; Since the lifting equipment horizontally hoists the square frame 1 towards the ground, when the outriggers 2 are telescopically adjusted according to the ground flatness and locked, the square frame 1 is still horizontal at this time. Thus, the four outriggers 2 can be automatically adjusted according to the irregular ground and complete self-locking. Subsequently, it is beneficial for the square frame 1 to still be in a horizontal state after landing on the ground, enabling the pipeline stress in the equipment to be evenly distributed; In addition, since the upward movement distance of the outrigger 2 is affected by the ground height, the distances between the nuts 4 at each position and the inner bottom end of the square frame 1 are different. By setting the first spring 8, during the process of the L-shaped pushing frame 7 pushing the rack 6, causing the rack 6 to move and the gear 5 to rotate, when the nut 4 abuts against the inner bottom end of the square frame 1, the rack 6 cannot move at this time. At this time, the L-shaped pushing frame 7 pushing the rack 6 only compresses the first spring 8, which is beneficial for keeping the four nuts 4 on the same horizontal plane and ensuring that the square frame 1 is horizontal.
[0025] As a further embodiment of the present invention, it further includes: A sliding groove 19 is opened at the end of the rack 6; A sliding block 20, both ends of the sliding block 20 are slidably connected in the sliding groove 19. A lead screw 21 is rotatably connected to the side wall of the sliding block 20. The end of the lead screw 21 penetrates through the outer side wall of the square frame 1 and is threadedly connected to the square frame 1. A regulating nut 22 is fixedly connected to the end of the lead screw 21; Specifically, by setting the sliding groove 19 and the sliding block 20, during use, if the ground sinks and causes the square frame 1 to tilt, the adjusting nut 22 can be rotated to make the lead screw 21 rotate. Under the action of the threaded connection, the sliding block 20 pulls the rack 6 to move further, thereby adjusting the height of the four legs 2, and then leveling the square frame 1.
[0026] As a further embodiment of the present invention, it further includes: Two first limiting rods 15, which are symmetrically and slidably connected to the front and rear inner side walls of the square frame 1. A second spring 16 is fixedly connected between the first limiting rod 15 and the bracket of the square frame 1. Third connecting pins 1501 are fixedly connected to both ends of the first limiting rod 15; First T-shaped grooves 201 are formed on the outer side walls of the four legs 2, and the third connecting pins 1501 are slidably connected in the first T-shaped grooves 201; Two first through grooves 101, which are symmetrically formed on the front and rear outer side walls of the square frame 1; Two first fixing blocks 1502 are respectively fixedly connected to the side walls of the first limiting rod 15, and the first fixing blocks 1502 are slidably connected to the side walls of the first through grooves 101; Two first fixing seats 102 are respectively fixedly connected to the outer side walls of the square frame 1 corresponding to the positions of the two first fixing blocks 1502; Specifically, by setting the first limiting rod 15 and the first T-shaped groove 201, before the square frame 1 is transported, the first limiting rod 15 is pulled to slide, so that the two third connecting pins 1501 move along the first transverse grooves in the first T-shaped grooves 201 of the front and rear legs 2. Subsequently, the first fixing block 1502 and the first fixing seat 102 are fixed by bolts to limit the first limiting rod 15, thereby limiting the legs 2, so that the four legs 2 cannot slide, thus ensuring that the energy storage disc 11 is always in the energy storage state during transportation. When hoisting is required, the bolts are removed, and under the action of the second spring 16, the first limiting rod 15 resets, so that the third connecting pin 1501 moves to the middle position of the first T-shaped groove 201. During the upward movement of the legs 2 when they contact the ground, the third connecting pin 1501 will move along the first vertical groove in the first T-shaped groove 201.
[0027] As a further embodiment of the present invention, first counterweights 1503 are symmetrically and fixedly connected to both ends of the first limiting rod 15; by providing the first counterweights 1503, during the process of hoisting the square frame 1, if the square frame 1 is tilted left and right, under the action of the first counterweights 1503, the first limiting rod 15 slides, and then the two third connecting pins 1501 move along the first transverse grooves in the first T-shaped grooves 201 of the front and rear legs 2, thereby completing the locking of the legs 2. At this time, even if the legs 2 contact the ground, they cannot move, and the limit on the energy storage disc 11 will not be released. At this time, the lifting equipment should be adjusted to level the square frame 1 again and then hoist the square frame 1 onto the ground; To facilitate observing whether the square frame 1 is tilted left and right, a pointer can be fixed on the first fixing block 1502, and at the same time, scale lines are marked at corresponding positions on the outer side wall of the square frame 1. When the pointer deviates from the scale line at the specified position, it indicates that the square frame 1 is tilted left and right, and the lifting attitude of the lifting equipment should be adjusted in a timely manner to level the square frame 1.
[0028] As a further embodiment of the present invention, it further includes: Two second limiting rods 17, which are symmetrically and slidably connected to the left and right inner side walls of the square frame 1. A third spring 18 is fixedly connected between the second limiting rods 17 and the brackets of the square frame 1. Fourth connecting pins 1701 are fixedly connected to both ends of the second limiting rods 17; Second T-shaped grooves 202 are formed on the outer side walls of all four legs 2, and the fourth connecting pins 1701 are slidably connected in the second T-shaped grooves 202; Two second through grooves 103, which are symmetrically formed on the left and right outer side walls of the square frame 1; Two second fixing blocks 1702, which are respectively fixedly connected to the side walls of the second limiting rods 17, and the second fixing blocks 1702 are slidably connected to the side walls of the second through grooves 103; Two second fixing seats 104, which are respectively fixedly connected to the outer side walls of the square frame 1 corresponding to the positions of the two second fixing blocks 1702; Second counterweights 1703 are symmetrically and fixedly connected to both ends of the second limiting rods 17; Specifically, by providing the second limiting rods 17 and the second counterweights 1703, the operation process here is the same as above. If the square frame 1 is tilted forward and backward, the second limiting rods 17 slide under the action of the counterweights, thereby locking the four legs 2, and the power of the energy storage disc 11 cannot be released; That is to say, only when the rectangular frame 1 is in a horizontal state and lands on the ground can the four legs 2 move upward. After all four limit rods leave the limit holes 1101, the energy storage disc 11 rotates to lock the four legs 2, thus avoiding the problem of the energy storage disc 11 rotating incorrectly due to operation errors, resulting in incorrect locking of the legs 2 and failure to level the rectangular frame 1.
[0029] As a further embodiment of the present invention, an arc-shaped limit groove 1001 is provided at the bottom end of the connecting frame 10, and a slider 1002 is fixedly connected to the surface of the rotating shaft of the energy storage disc 11. The slider 1002 is slidably connected in the arc-shaped limit groove 1001; Specifically, by providing the arc-shaped limit groove 1001 and the slider 1002, the rotation trajectory of the energy storage disc 11 is limited.
[0030] As a further embodiment of the present invention, an anti-slip pad 203 is fixedly connected to the bottom end of the leg 2 to increase the damping between the leg 2 and the ground and prevent the rectangular frame 1 from sliding.
[0031] The working principle of the present invention: First, the rectangular frame 1 is horizontally lifted towards the ground by a lifting device, so that the legs 2 at the bottom end of the rectangular frame 1 are close to the ground. During the process of the legs 2 approaching the ground, one or several of the legs 2 will first come into contact with the high points on the ground. Under the extrusion of the ground, the legs 2 move upward, causing the limit plates 13 to move upward and leave the limit holes 1101. Subsequently, the rectangular frame 1 continues to move downward, causing the remaining legs 2 to come into contact with the low points on the ground. Under the extrusion of the ground, the remaining legs 2 move upward. At this time, all four legs 2 are in full contact with the ground, causing the remaining limit plates 13 to move upward and leave the limit holes 1101, and finally canceling the limit on the energy storage disc 11; After all four limit plates 13 leave the limit holes 1101, under the action of the torsion spring 12, the energy storage disc 11 rotates, causing the second connecting pin 1102 to move along the driving chute 1401. Under the push of the second connecting pin 1102, the L-shaped pushing seat 14 moves, causing the U-shaped driving seat 9 to move, causing the L-shaped pushing frame 7 to move along the driving inclined groove 901. Under the drive of the driving inclined groove 901, the L-shaped pushing frame 7 pushes the rack 6 to move, causing the rack 6 to mesh with the gear 5. The gear 5 drives the nut 4 to rotate. Under the action of the threaded connection, the nut 4 moves upward and abuts against the inner bottom end of the rectangular frame 1, thus locking the four legs 2. At this time, the four legs 2 cannot move upward along the rectangular frame 1, enabling the four legs 2 to automatically adjust according to the irregular ground and complete self-locking. Subsequently, it is beneficial to keep the rectangular frame 1 in a horizontal state and evenly distribute the pipeline stress in the equipment; In addition, since the upward movement distance of the outrigger 2 is affected by the ground height, the distances between the nuts 4 at various positions and the inner bottom end of the square frame 1 are different. By providing the first spring 8, during the process that the L-shaped pusher 7 pushes the rack 6 to move and rotate the gear 5, when the nut 4 abuts against the inner bottom end of the square frame 1, the rack 6 cannot move at this time. At this time, when the L-shaped pusher 7 pushes the rack 6, it will only compress the first spring 8, which is beneficial to keeping the four nuts 4 on the same horizontal plane and ensuring that the square frame 1 is horizontal.
