Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for silo construction, and in particular relates to a pre-assembled frame for large-diameter silos. Background Technology

[0002] In the on-site assembly and construction of large-diameter silos (such as grain storage silos and chemical raw material storage silos), the pre-assembly jig is a core auxiliary equipment. It needs to provide stable support, angle adjustment and safe fixation for large silo components, and provide a precise benchmark for subsequent welding and splicing operations.

[0003] The invention patent with announcement number CN202321567U discloses a grain wind-powered conveyor, which includes a blower (2), an air duct (16), a storage hopper (6), a discharge hopper (4), a gate (8), a distribution box (5), a conveying wear-resistant pipe (14), and an output hose (13). The blower and the air duct are fixed on a mobile trolley (20). One end of the air duct is connected to the blower, and the other end is movably connected to one end of the conveying wear-resistant pipe. The other end of the conveying wear-resistant pipe is connected to the output hose. A discharge hopper is provided on the air duct, and a distribution box is provided on the discharge hopper. Rotating conveying blades (9) are provided in the distribution box. A storage hopper is provided on the distribution box, and a gate (8) is provided between the storage hopper and the distribution box to open and close the storage hopper. This utility model is placed outside the grain depot and can be used independently or in combination to complete the grain storage, transfer and release. It not only occupies a small area, but also has a conveying distance of up to 50 meters and a conveying efficiency of 20-25 tons / hour. Moreover, it has low labor intensity and low equipment investment.

[0004] However, the above structure still has shortcomings. The device uses a manual crank to drive the lead screw to adjust the angle of the jig. Each adjustment requires the cooperation of 2-3 workers and takes a long time. It is difficult to meet the pre-assembly requirements of large-diameter silo components. Therefore, it is necessary to provide a new large-diameter silo pre-assembly jig to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a large-diameter silo pre-assembly frame that replaces the traditional manual crank with an adjustable structure, which can shorten the angle adjustment time, improve work efficiency, and meet the construction needs of large-diameter silo components.

[0006] To solve the above-mentioned technical problems, the present invention provides a large-diameter silo pre-loading rack, comprising: a base mounted on a vehicle, the base having a pre-loading rack structure, the pre-loading rack structure including an adjustment mechanism, the adjustment mechanism including a base, a mounting block, a bottom plate, a first mounting seat, a second mounting seat, a movable block, a lead screw, a motor, and a support block; the mounting block is fixedly mounted on the top of the base, the bottom plate is hinged to the mounting block, the first mounting seat is fixedly mounted on the bottom of the bottom plate, the second mounting seat is located on the top of the base, and the top and bottom of the movable block are movably connected to the first and second mounting seats, respectively. The base has a concave groove on its top. The lead screw is rotatably installed in the concave groove. The motor is fixedly installed on one side of the outer wall of the base. One end of the lead screw extends to the outside of one side of the concave groove and is fixedly connected to the output shaft of the motor. A moving block is threaded on the lead screw. The moving block is slidably connected to the concave groove. The top of the moving block is fixedly connected to the top of the mounting base.

[0007] As a further embodiment of this utility model, a support block is fixedly installed on the top of the base, the support block and the mounting block are symmetrically distributed from left to right, and the top of the support block is in contact with the bottom of the base plate.

[0008] As a further embodiment of this utility model, the pre-assembled tire frame structure also includes a clamping assembly. The clamping assembly includes two placement clamping blocks, two arc-shaped rubber pads, two fixing blocks, two upper clamping blocks, two arc-shaped rubber pads, two connecting blocks, and two cylinders. The two placement clamping blocks are symmetrically fixedly installed on the top of the base plate. The same placement clamping block is placed on both placement clamping blocks. An arc-shaped rubber pad is provided between the placement clamping blocks.

[0009] As a further embodiment of this utility model, both upper clamping blocks are clamped on the placement clamping block, and an arc-shaped rubber pad is provided between the upper clamping block and the placement clamping block. Two fixing blocks are respectively fixedly installed on the outer walls of the two upper clamping blocks. The two fixing blocks are connected and fixed by two connecting blocks.

[0012] Compared with related technologies, the large-diameter silo pre-assembly jig provided by this utility model has the following beneficial effects: 1. This utility model adopts an adjustment structure with a motor lead screw to replace the traditional manual crank, which can shorten the angle adjustment time, improve work efficiency, and meet the construction needs of large-diameter silo components; 2. This utility model, through the auxiliary support of the support block, can avoid the tilting and imbalance of the base plate during the adjustment process, thus improving safety; 3. The closed-loop clamping structure formed by the placement of clamping blocks and upper clamping blocks can be adapted to silo components of different specifications, and its stability far exceeds that of the traditional bolt-pressing structure. The arc-shaped rubber pads one and two are made of wear-resistant nitrile rubber, which can prevent the metal clamping blocks from directly contacting the components and protect the appearance and structural integrity of the components.

Detailed Implementation

[0016] Please refer to the following: Figures 1 to 3 ,in, Figure 1 This is a front view structural diagram of the present utility model; Figure 2 This is a schematic diagram of the three-dimensional structure of the present invention. Figure 1 ; Figure 3 This is a schematic diagram of the three-dimensional structure of the present invention. Figure 2 The large-diameter silo pre-loading rack includes: a base 1 mounted on a vehicle, the base 1 having a pre-loading rack structure, the pre-loading rack structure including an adjustment mechanism, the adjustment mechanism including the base 1, mounting block 2, base plate 3, mounting seat one 4, mounting seat two 5, movable block 6, lead screw 7, motor 8, and support block 9. The mounting block 2 is fixedly mounted on the top of the base 1, the base plate 3 is hingedly mounted on the mounting block 2, the mounting seat one 4 is fixedly mounted on the bottom of the base plate 3, the mounting seat two 5 is located on the top of the base 1, and the top and bottom of the movable block 6 are movably connected to the mounting seat one 4 and the mounting seat two 5, respectively. The top of the base 1 has a concave groove, the lead screw 7 is rotatably installed in the concave groove, the motor 8 is fixedly installed on one side of the outer wall of the base 1, one end of the lead screw 7 extends to the outside of one side of the concave groove and is fixedly connected to the output shaft of the motor 8, a moving block is threaded on the lead screw 7, the moving block is slidably connected to the concave groove, and the top of the moving block is fixedly connected to the top of the mounting base 5.

[0017] When the motor 8 is started, it rotates forward (or reverse). The output shaft of the motor 8 drives the lead screw 7 to rotate. Since the moving block (not shown in the figure) is threadedly connected to the lead screw 7 and slides against the concave groove, the moving block moves horizontally to the right (or left) along the concave groove, thereby driving the mounting seat 2 5 to move synchronously. When the mounting seat 2 5 moves, the movable block 6 rotates around the pin of the mounting seat 1 4 and the mounting seat 2 5, pushing the base plate 3 to flip upward (or downward) with the hinge point of the mounting block 2 as the axis. At this time, the rubber pad on the top of the support block 9 slides in contact with the bottom of the base plate 3, providing auxiliary support and preventing the base plate 3 from tilting too quickly. When the base plate 3 flips to the target angle, the motor 8 is stopped, and the angle adjustment is completed. If fine adjustment is required, the motor 8 can be jogged until the angle is accurately achieved. The model of the motor 8 is Y100L-2.

[0018] A support block 9 is fixedly installed on the top of the base 1. The support block 9 and the mounting block 2 are symmetrically distributed from left to right. The top of the support block 9 is in contact with the bottom of the base plate 3.

[0019] The pre-assembled jig structure also includes a clamping assembly, which includes two placement clamping blocks 10, two arc-shaped rubber pads 11, two fixing blocks 12, two upper clamping blocks 13, two arc-shaped rubber pads 14, two connecting blocks 15, and two cylinders 16. The two placement clamping blocks 10 are symmetrically fixedly installed on the top of the base plate 3, and the same placement clamping block 100 is placed on the two placement clamping blocks 10. An arc-shaped rubber pad 11 is provided between the placement clamping blocks 10 and the placement clamping block 100.

[0020] Both upper clamping blocks 13 are clamped on the placement clamping block 100. An arc-shaped rubber pad 14 is provided between the upper clamping block 13 and the placement clamping block 100. Two fixing blocks 12 are respectively fixedly installed on the outer walls of the two upper clamping blocks 13. The two fixing blocks 12 are connected and fixed by two connecting blocks 15. Two cylinders 16 are symmetrically installed on the top of the base plate 3. The two cylinders 16 are respectively located on both sides of the placement clamping block 100. The output shafts of the two cylinders 16 are respectively connected to the bottom of the two connecting blocks 15.

[0021] The silo component to be pre-installed is smoothly hoisted onto the two placement clamping blocks 10, ensuring that the center of the component is aligned with the center of the base plate 3, and that the arc-shaped rubber pad 11 is fully in contact with the surface of the component. The connecting block 15 is moved upward by the output shaft of the cylinder 16. Since the connecting block 15 is connected to the fixing block 12 of the upper clamping block 13, the upper clamping block 13 moves downward synchronously with the connecting block 15. When the arc-shaped rubber pad 14 on the inner side of the upper clamping block 13 is in close contact with the top surface of the placement clamping block 100, the cylinder 16 is closed, completing the upper and lower closed-loop clamping of the component. At this time, the component has no lateral or longitudinal displacement. The model of the cylinder 16 is SC63×100.

[0022] A buffer collar 17 is slidably sleeved on the placement clamping block 100. Two first hooks 18, two second hooks 19 and two third hooks 20 are symmetrically installed on the outer wall of the buffer collar 17. Two hooks 1 21 and two hooks 22 are symmetrically installed on the base 1. Two hooks 3 23 are symmetrically installed on the outer wall of the clamping block 13.

[0023] The third hook 23 and the third hook 20 are connected and fixed by the third connecting rope 26. The second hook 22 and the second hook 19 are connected and fixed by the second connecting rope 25. The first hook 21 and the first hook 18 are connected and fixed by the first connecting rope 24.

[0024] Slide the buffer collar 17 into one end of the clamping block 10 to ensure that the buffer collar 17 fits tightly against the outer wall of the component. Connect the first hook 21 to the first hook 18 with the connecting rope 24 and tighten the rope with a tensioner. Similarly, connect the second hook 22 to the second hook 19 (connecting rope 25) and the third hook 23 to the third hook 20 (connecting rope 36) to form a three-dimensional tension and fixing system of the base buffer collar and the upper clamping block buffer collar, which can provide support and cushioning for the lower part of the component.
