Description

Technical Field

[0001] The present invention relates to the technical field of fiberglass storage tank transportation, and particularly to an adjustable fixing device for fiberglass storage tanks. Background Art

[0002] Fiberglass storage tanks are one of the fiberglass products. They are mainly made of glass fiber as the reinforcing agent and resin as the binder through computer-controlled machine winding. Fiberglass storage tanks are made of new composite materials. Fiberglass storage tanks have corrosion resistance, high strength, light weight, and long service life. Due to their flexible designability and strong processability, fiberglass storage tanks can be divided into vertical storage tanks, horizontal storage tanks, etc.

[0003] Existing horizontal storage tanks are often transported, and most of the liquids contained in horizontal storage tanks are flammable and explosive liquids. Therefore, during transportation, it is necessary to fix them to avoid excessive reaction of the internal liquids due to excessive vehicle bumps, which is prone to accidents.

[0004] After retrieval, the Chinese patent with the publication number CN214525907U discloses a two-saddle fiberglass horizontal storage tank convenient for fixed transportation. A fixing part is arranged at the top of the support base. However, there are still the following defects. Existing fixing devices usually use a hoisting machine to hoist the fiberglass storage tank onto the fixing seat and then tie it tightly with straps. Since different fiberglass storage tanks are different, fixing seats of different sizes are correspondingly made for different fiberglass storage tanks, resulting in low adaptability. Moreover, existing fixing devices are not convenient for fixing multiple directions of the fiberglass storage tank at the same time, resulting in low fixing strength. Summary of the Invention

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an adjustable fixing device for an FRP storage tank, having the following beneficial effects:

[0016] 1. In the present invention, the power assembly makes the clamping assembly move inward and clamp both sides of the FRP storage tank body.

The elastic arc plate can position and straighten the FRP storage tank body to prevent the FRP storage tank body from moving after being placed. When the clamping frame moves inward, the elastic arc plate is deformed by force and bends into the avoidance groove, and the top block contacts the FRP storage tank body and moves outward along the third chute under the action of force until the top block is embedded in the clamping frame, and the clamping frame clamps the FRP storage tank body through its clamping groove.

[0018] 3. In the present invention, the inward movement of the clamping frame drives the top frame to move inward to a suitable position, and then the plug pin is inserted into the pin hole under the action of gravity, thereby completing the fixation of the clamping frame.

[0019] 4. In the present invention, the inward movement of the clamping frame relaxes the wire on the winding roller through the wire, so that the torsion spring rebounds and drives the winding roller to rotate and wind the wire. At the same time, the rotating plate makes a flipping movement under the drive of the torsion spring and presses the FRP storage tank body. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Refer to Figures 1 - 5, An adjustable fixing device for a fiberglass storage tank, comprising a bottom plate 7 and a fiberglass storage tank body 2. Two lifting rings 1 distributed in an opposed manner are fixedly mounted on the outer wall of the top of the fiberglass storage tank body 2 by bolts. Two support plates 9 for supporting the fiberglass storage tank body 2 are fixedly mounted on the top of the bottom plate 7 by bolts. A plurality of first chutes 10 are formed in the top of the bottom plate 7. A clamping assembly 6 for fixing the side of the fiberglass storage tank body 2 is arranged in the first chutes 10. Power assemblies 5 for moving the clamping assembly 6 are arranged on both sides of the bottom plate 7. A fixing assembly 4 for locking the position of the clamping assembly 6 is arranged between the clamping assemblies 6. A tying assembly 3 for secondarily fixing the fiberglass storage tank body 2 is arranged between the two support plates 9 on the top of the bottom plate 7. Pressing assemblies 8 for pressing both ends of the fiberglass storage tank body 2 are arranged at both ends of the bottom plate 7. The fiberglass storage tank body 2 is hoisted onto the bottom plate 7 by a crane, and then the power assemblies 5 are used to move the clamping assembly 6 inwards to clamp both sides of the fiberglass storage tank body 2. At the same time, the tying assembly 3 performs a tying operation on the fiberglass storage tank body 2. At the same time, the pressing assemblies 8 located at both ends of the bottom plate 7 press both ends of the fiberglass storage tank body 2 while the clamping assembly 6 clamps the fiberglass storage tank body 2. After the fixing is completed, the position of the clamping assembly 6 is fixed by the fixing assembly 4. Thus, the clamping assembly 6 can fix fiberglass storage tank bodies 2 of different sizes and simultaneously press and fix multiple orientations of the fiberglass storage tank body 2, thereby further improving the fixing stability.

[0028] In the present invention, the clamping assembly 6 includes a plurality of clamping frames 11 which are slidably connected inside the first chute 10. Clamping grooves 22 are formed on one side of each of the plurality of clamping frames 11. A pre-extrusion assembly for positioning the glass fiber reinforced plastic storage tank body 2 is provided inside the clamping frame 11. A bidirectional threaded rod 12 is threadedly connected between two opposite clamping frames 11, and the bidirectional threaded rod 12 is rotatably connected to the support plate 9. The pre-extrusion assembly includes a plurality of third chutes 26 which are formed on the inner walls of both sides of the clamping frame 11. A top block 23 is slidably connected between the plurality of third chutes 26. An avoidance groove 25 is formed on one side of the top block 23. An elastic arc plate 24 is fixed in the avoidance groove 25 by bolts. A spring 27 is fixed to one side of the top block 23 by bolts, and one end of the spring 27 is fixed to the inner wall of one side of the clamping frame 11. The power assembly 5 includes two second synchronous belt pulleys 16 which are respectively rotatably connected to both sides of the bottom plate 7. A runner 15 is fixed to one end of the second synchronous belt pulley 16 by bolts. Synchronous belt wheels 13 are key-connected to both ends of the two bidirectional threaded rods 12. The two synchronous belt wheels 13 on the same side of the bottom plate 7 and the second synchronous belt pulley 16 are connected by a synchronous belt for transmission. By rotating the runner 15, the rotation of the runner 15 causes the second synchronous belt pulley 16 to drive the synchronous belt wheel 13 to rotate. The rotation of the synchronous belt wheel 13 causes the bidirectional threaded rod 12 to drive the two clamping frames 11 to move inward along the first chute 10. The elastic arc plate 24 can position and straighten the glass fiber reinforced plastic storage tank body 2, avoiding the movement of the glass fiber reinforced plastic storage tank body 2 after placement. When the clamping frame 11 moves inward, the elastic arc plate 24 deforms under force and bends into the avoidance groove 25, and the top block 23 contacts the glass fiber reinforced plastic storage tank body 2 and moves outward along the third chute 26 under force until the top block 23 is embedded in the clamping frame 11, and the clamping frame 11 clamps the glass fiber reinforced plastic storage tank body 2 through its clamping groove 22.

[0029] In the present invention, the fixing assembly 4 includes two top frames 18 which are respectively fixed between two adjacent clamping frames 11 by bolts. Two pin holes 14 distributed in an opposed manner are formed at the top of the bottom plate 7. Plug pins 17 which can be engaged with the pin holes 14 are inserted into the tops of the two top frames 18. By the inward movement of the clamping frame 11, the top frame 18 is driven to move inward to a proper position, and then the plug pin 17 is inserted into the pin hole 14 under the action of gravity, thus completing the fixation of the clamping frame 11.

[0030] In the present invention, the tying-down assembly 3 includes a plurality of sliding frames 19 which are respectively slidably connected inside the second chute 20. An elastic tie strap 21 is detachably connected between two opposite sliding frames 19. The plurality of sliding frames 19 can contact the top frame 18. By winding the elastic tie strap 21 around the glass fiber reinforced plastic storage tank body 2 and respectively connecting and fixing the two ends of the elastic tie strap 21 to the sliding frames 19, further pressing and fixing of the glass fiber reinforced plastic storage tank body 2 is realized.

[0031] In the present invention, the pressing assembly 8 includes two mounting brackets 33. Positioning rings 29 are fixed to the outer walls on both sides of the two mounting brackets 33 by bolts. A rotating plate 32 is rotatably connected between the inner walls on both sides of the mounting bracket 33. A pressing plate 34 is fixed to one side of the rotating plate 32 by bolts. Both ends of the two rotating plates 32 pass through the mounting bracket 33 and are key-connected to a winding roller 30. A steel wire 28 is fixed to one side of the winding roller 30 by bolts. One end of the steel wire 28 passes through the positioning ring 29 and is fixed to the clamping bracket 11. Torsion springs 31 are sleeved on both ends of the rotating plate 32, and both ends of the torsion springs 31 are respectively fixed to the mounting bracket 33 and the winding roller 30. Profiled pressing grooves for extruding the glass fiber reinforced plastic storage tank body 2 are formed on one side of the two pressing plates 34. Rubber pads are bonded in the profiled pressing grooves. When the clamping bracket 11 moves inward, the winding roller 30 is loosened through the steel wire 28, so that the torsion spring 31 rebounds and drives the winding roller 30 to rotate and wind the steel wire 28. At the same time, the rotating plate 32 is driven by the torsion spring 31 to perform a flipping action and press the glass fiber reinforced plastic storage tank body 2.

[0032] Working principle of this embodiment: During use, the glass fiber reinforced plastic storage tank body 2 is hoisted onto the bottom plate 7 by a crane. Then, the elastic binding belt 21 is wound around the glass fiber reinforced plastic storage tank body 2, and both ends of the elastic binding belt 21 are respectively connected and fixed to the sliding frame 19. Then, by rotating the rotating wheel 15, the rotation of the rotating wheel 15 causes the second synchronous pulley 16 to drive the first synchronous pulley 13 to rotate. The rotation of the first synchronous pulley 13 causes the bidirectional threaded rod 12 to drive the two clamping brackets 11 to move inward along the first chute 10. The elastic arc plate 24 can position and straighten the glass fiber reinforced plastic storage tank body 2, preventing the glass fiber reinforced plastic storage tank body 2 from moving after being placed. When the clamping bracket 11 moves inward, the elastic arc plate 24 is deformed by force and bends into the avoidance groove 25, and the top block 23 contacts the glass fiber reinforced plastic storage tank body 2 and moves outward along the third chute 26 under the action of force until the top block 23 is embedded in the clamping bracket 11, and the clamping bracket 11 clamps the glass fiber reinforced plastic storage tank body 2 through its clamping groove 22. At the same time, the top frame 18 presses the sliding frame 19, and the sliding frame 19 pulls the elastic binding belt 21 to tightly bind the glass fiber reinforced plastic storage tank body 2. At the same time, when the clamping bracket 11 moves inward, the winding roller 30 is loosened through the steel wire 28, so that the torsion spring 31 rebounds and drives the winding roller 30 to rotate and wind the steel wire 28. At the same time, the rotating plate 32 is driven by the torsion spring 31 to perform a flipping action and press the glass fiber reinforced plastic storage tank body 2. After the fixation is completed, the clamping bracket 11 moves inward to drive the top frame 18 to move inward to a suitable position, and then the pin 17 is inserted into the pin hole 14 under the action of gravity, thus completing the fixation of the clamping bracket 11. Therefore, the clamping component 6 can fix glass fiber reinforced plastic storage tank bodies 2 of different sizes, and at the same time, multiple orientations of the glass fiber reinforced plastic storage tank body 2 are tightly fixed simultaneously, further improving the fixation stability.
