Description

Technical Field

[0001] The present invention relates to the field of container positioning, and more particularly to a container transfer fixture. Background Art

[0002] The types and definitions of containers can be classified according to different application fields and needs. Generally speaking, a container refers to a structure or equipment used to store, transport or process substances (such as buckets, oil tanks, pressure vessels, etc.). A transfer fixture is a fixture that clamps and positions the container during the container transfer process. After the fixture clamps and positions the container, it is convenient to lift the fixture with a crane to drive the container transfer and ensure the stability of the container during the transfer process.

[0003] In the prior art, most clamps for pressure vessels use two clamping jaws to clamp the pressure vessel. For example, the prior art (Chinese invention patent application with publication number CN110948419A and Chinese utility model patent with publication number CN219582647U) discloses a convenient clamp for metal pressure vessels and a new type of clamp for metal pressure vessels, respectively. Both clamps use two clamping jaws to clamp the pressure vessel. Although a new type of metal pressure vessel clamp with announcement number CN219582647U is provided with a locking assembly, which allows the clamping parts to be quickly disassembled and replaced with clamping parts of different specifications, this increases the difficulty of adjustment and spare parts management for multi-specification production or operation, reduces work efficiency, and each replacement of the jaws requires additional time and effort, and the jaws themselves may increase the risk of wear or reduced positioning accuracy due to frequent replacement.

The hot air blown by hot air blower 1 and hot air blower 2 is discharged from exhaust port 1 and exhaust port 2 respectively and blown onto the outer surface of the container, heating the contact area between the outer surface of the container and the sealing gasket, reducing the influence of temperature difference on the clamping force and adsorption force of the clamp, and avoiding instability caused by temperature difference.

The contact characteristics of the container after surface grinding are more uniform, and the stress distribution during clamping is more reasonable, reducing the risk of indentation, scratches or deformation of the container surface due to local high pressure, eliminating larger surface irregularities (such as burrs or weld residues), avoiding the displacement of the clamping block or uneven force due to local interference during clamping, helping the sealing gasket to form a more uniform contact with the container surface, and reducing micro-leakage in the contact area.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10 A container transfer fixture comprises a clamping assembly clamped on the outside of the container, wherein the clamping assembly comprises two symmetrical clamping plates 1, two locking screws 2 symmetrically screwed into the two clamping plates 1, two clamping plates 3 sleeved on the outside of the two clamping plates 1, two locking screws 4 symmetrically screwed into the two clamping plates 3, and four clamping parts 5 respectively fixed to one side of the two clamping plates 1 and the two clamping plates 3; The clamping portion 5 includes an arc-shaped clamping block 51 fixedly connected to one side of the clamping plate 1 or the clamping plate 2 3, an adsorption cavity 52 opened inside the arc-shaped clamping block 51, a sealing gasket 53 fixedly connected to one side of the arc-shaped clamping block 51, and an intra-cavity air pressure regulating portion 54 fixedly connected to the other side of the arc-shaped clamping block 51 and extending outward through the clamping plate 1 or the clamping plate 2 3.

[0023] The intra-cavity air pressure regulating part 54 includes a column 541 fixedly connected to one side of the arc-shaped clamping block 51, a hollow cavity 542 opened inside the column 541 and connected to the adsorption chamber 52, a piston 543 movably connected in the hollow cavity 542, a screw 544 screwed in the column 541, and an adjusting disk 545 fixedly connected to one end of the screw 544, and the other end of the screw 544 is rotatably connected to one side of the piston 543.

[0024] A guide rod 546 is fixedly connected to one side of the piston 543 , and a relief groove 547 is provided inside the column 541 to accommodate the guide rod 546 and communicate with the hollow cavity 542 .

[0025] By adopting the above technical solution, the two clamping plates 1 are symmetrically placed on the front and back sides of the container, and then the locking screw 2 is rotated to make the two clamping plates 1 move toward each other, and the distance between the two clamping plates 1 becomes smaller so that the sealing gasket 53 on the arc-shaped clamping block 51 on one side of the two clamping plates 1 can contact the surface of the container, and the two clamping plates 2 3 are symmetrically placed on the left and right sides of the container and sleeved on the two ends of the two clamping plates 1, and then the locking screw 2 4 is rotated to make the two clamping plates 2 3 move toward each other, and the sealing gasket 53 on the arc-shaped clamping block 51 on one side of the two clamping plates 2 3 can contact the surface of the container. When the four arc-shaped clamping blocks 5 After being evenly pressed on the container surface and applying the clamping force to the container, the laminating effect on the container surface is enhanced, and the clamping stability is further improved. The guide rod 546 is used to guide the movement of the piston 543. Since a plurality of adsorption chambers 52 are provided, and the air pressure regulating parts 54 in the plurality of chambers can individually adjust the pressures in the plurality of adsorption chambers 52, the clamping stability is further improved, and the partitioned adsorption positioning of the pressure container and the precise laminating of different areas of the arc-shaped container are realized, and the problem of uneven distribution of the clamping force caused by the irregular surface of the container or the size error is reduced, thereby improving the clamping effect and reliability.

[0026] like Figure 4 and Figure 5 As shown, a heating plate 55 is fixedly connected inside the arc-shaped clamp block 51, and one side of the heating plate 55 is in contact with one side of the sealing gasket 53. The upper and lower ends of the arc-shaped clamp block 51 are connected with a softness-enhancing and adhesion-enhancing component 6, and the softness-enhancing and adhesion-enhancing component 6 includes two box bodies 61 symmetrically fixed to the upper and lower ends of the arc-shaped clamp block 51, two hot air blowers 62 fixed inside the two box bodies 61, and two exhaust ports 63 obliquely opened inside the two box bodies 61, the air outlet end of the hot air blower 62 faces the exhaust port 63, and the air inlet end of the hot air blower 62 passes through the box body 61 and extends outward.

[0027] Two sets of exhaust vents 64 are symmetrically provided inside the two box bodies 61, and two sets of hot air blowers 65 are fixedly connected inside the two box bodies 61. The air outlet ends of the hot air blowers 65 face the exhaust vents 64, and the air inlet ends of the hot air blowers 65 penetrate the box bodies 61 and extend outward. A plurality of air guide plates 66 are connected to the inner wall of the exhaust vents 64.

[0028] Motors 67 are fixedly connected to both sides of the two box bodies 61, one ends of the multiple air guide plates 66 are rotatably connected to the inner wall of the second exhaust port 64, and the other ends of the multiple air guide plates 66 are fixedly connected to sprockets 68, and the multiple sprockets 68 are connected by a chain belt 69. The output shaft of the motor 67 penetrates into the second exhaust port 64 and is fixedly connected to one of the sprockets 68.

[0029] By adopting the above technical solution, the heating plate 55 (electric heating plate, which belongs to the mature existing technology and will not be described in detail here) can heat the sealing gasket 53 (rubber sealing gasket, which belongs to the mature existing technology and will not be described in detail here) to reduce its hardness and make it easier to fit the container surface, and the sealing gasket 53 may soften or expand, further filling the tiny gap between the arc clamping block 51 and the container surface, thereby enhancing the sealing performance. In particular, when the container surface is uneven or has microscopic pits, heating can significantly improve the sealing contact effect. The hot air blown by the hot air blower 1 62 and the hot air blower 2 65 is discharged from the exhaust port 1 63 and the exhaust port 2 64 respectively and blown onto the outer surface of the container, so as to improve the contact area between the outer surface of the container and the sealing gasket 53. Heating is performed to reduce the influence of the temperature difference between the outer surface of the container and the sealing gasket 53 on the clamping force and adsorption force of the clamp, and to avoid the instability caused by the temperature difference. The motor 67 can drive one of the sprockets 68 and the air guide plate 66 to rotate, and the rotating sprocket 68 drives the other sprockets 68 and the air guide plate 66 to rotate through the chain belt 69, thereby adjusting the blowing direction of the hot air discharged from the exhaust port 2 64, so that the hot air can be blown to different positions on the surface of the container, and the electric energy required to drive the hot air blower 1 62, the hot air blower 2 65, the heating plate 55 and the motor 67 can be supplied by installing an energy storage module on the splint 1 1 and the splint 2 3. The energy storage module is composed of a battery, a circuit board and other structures, which is a conventional design and will not be repeated here.

[0030] like Figure 4 , Figure 6-Figure 8As shown, both sides of the arc-shaped clamping block 51 are connected with a device surface processing unit 7, and the device surface processing unit 7 includes a side plate 71 fixedly connected to one side of the arc-shaped clamping block 51, a screw rod 72 screwed in the side plate 71, a slide seat 73 slidably connected to one side of the arc-shaped clamping block 51, an adjustment component 75 connected to the inside of the slide seat 73, and sandpaper 74 connected to the adjustment component 75. One end of the screw rod 72 is rotatably connected to one side of the slide seat 73, and a through groove for accommodating the screw rod 72 is opened inside the clamping plate 1 and the clamping plate 2 3, and the other end of the screw rod 72 passes through the through groove and extends outward.

[0031] The adjusting assembly 75 includes two rotating rods 751 symmetrically connected to the inside of the slide 73, two gears 755 rotatably connected to the upper end of the slide 73 and respectively connected to the two rotating rods 751, a fixed seat 752 fixed to the upper end of the slide 73, a screw rod 3 753 threaded inside the fixed seat 752, a slide 2 754 slidably connected to the upper end of the slide 73, and a limit tooth key integrally formed on one side of the slide 2 754 for limiting the rotation of the gear 1 755, one end of the screw rod 3 753 is rotatably connected to one side of the slide 2 754, and the two ends of the sandpaper 74 are respectively wrapped around the outside of the two rotating rods 751.

[0032] By adopting the above technical solution, before clamping the container with the splint 1 and the splint 2 3, the slide 1 73 can be driven to move on one side of the arc-shaped clamping block 51 by rotating the screw 2 72, so that the slide 1 73 is close to the container surface, and before the arc-shaped clamping block 51 contacts the container surface, the sandpaper 74 contacts the container surface first, and then the splint 1 and the splint 2 3 are rotated to rotate the splint 1 and the splint 2 3 outside the container, so that the sandpaper 74 rotates and grinds on the outer surface of the container to remove the oxide layer, dirt or irregular protrusions, thereby improving the flatness of the container surface. The contact characteristics of the container after surface grinding are more uniform, and the stress distribution during clamping is more reasonable, which reduces the risk of indentation, scratches or deformation of the container surface caused by local high pressure, and eliminates larger surface irregularities (such as burrs or welds). Residue), avoid the offset or uneven force of the clamping block caused by local interference during the clamping process, help the sealing gasket 53 to form a more uniform contact with the container surface, reduce the micro-leakage in the contact area, rotate the screw three 753 to drive the slide two 754 to move, when the slide two 754 and the gear one 755 move in opposite directions, the limit tooth key on the slide two 754 can be separated from the gear one 755, and the limit on the gear one 755 is cancelled. At this time, the two gears one 755 can be rotated, and the rotation of the two gears one 755 respectively drives the two rotating rods one 751 to rotate, one of the rotating rods one 751 reels the sandpaper 74, and the other rotating rod one 751 rotates to release the sandpaper 74 pre-wound on this rotating rod one 751, so that the worn sandpaper 74 can be quickly replaced.

[0033] like Figure 7 , Fig. 9 and Fig.10 As shown, the sliding seat 1 73 is also connected to a grinding surface uniform component 76, and the grinding surface uniform component 76 includes a movable seat 761 slidably connected to the sliding seat 1 73, a tooth groove 762 provided in the movable seat 761, a rotating rod 2 764 rotatably connected to the sliding seat 1 73 and located in the tooth groove 762, an incomplete gear 763 fixed to the outside of the rotating rod 2 764 and meshing with the tooth groove 762, a bevel flange 765 integrally formed on one side of the movable seat 761, and two movable teeth symmetrically provided in the movable seat 761. The movable groove 767, a plurality of guide posts 768 fixedly connected to the inner wall of the movable groove 767, a plurality of springs 769 respectively sleeved on the outside of the plurality of guide posts 768, a plurality of top blocks 766 located inside the movable seat 761 and movably sleeved on the outside of adjacent guide posts 768 at both ends, the two sides of the top blocks 766 are respectively in contact with the movable seat 761 and the sandpaper 74, the upper and lower ends of the slide seat 1 73 are rotatably connected with rubber rollers 77, and the upper and lower ends of the rotating rod 2 764 penetrate the slide seat 1 73 and are fixedly connected to the adjacent rubber rollers 77. The two ends of the spring 769 are respectively connected to the inner wall of the movable groove 767 and the top blocks 766.

[0034] By adopting the above technical scheme, when the sandpaper 74 contacts the surface of the container, the rubber roller 77 can also contact the surface of the container. When the plywood 1 and the plywood 2 3 rotate outside the container, the rubber roller 77 can also rotate and drive the rotating rod 2 764 to rotate. The rotation of the rotating rod 2 764 drives the incomplete gear 763 to rotate. The rotation of the incomplete gear 763 drives the movable seat 761 to move left and right inside the slide seat 1 73. When the movable seat 761 moves left and right, the inclined flange 765 on one side of the movable seat 761 will contact different top blocks 766, thereby pushing different top blocks 766 to move toward the direction of the sandpaper 74. The sandpaper 74 is supported by different top blocks 766, so that different areas of the sandpaper 74 are in contact with the container, avoiding uneven wear of various areas on the sandpaper 74 caused by a single contact area between the sandpaper 74 and the container, thereby affecting the grinding effect.

[0035] Method of use: symmetrically place the two clamps 1 on the front and back sides of the container, then rotate the locking screw 2 to make the two clamps 1 move towards each other, the distance between the two clamps 1 becomes smaller so that the arc-shaped clamping block 51 on one side of the two clamps 1 is close to the surface of the container, symmetrically place the two clamps 2 3 on the left and right sides of the container and sleeve them on the two ends of the two clamps 1, then rotate the locking screw 2 4 to make the two clamps 2 3 move towards each other, the arc-shaped clamping block 51 on one side of the two clamps 2 3 is close to the surface of the container, and rotating the screw 2 72 can drive the slide The seat 1 73 moves on one side of the arc clamping block 51, so that the slide seat 1 73 approaches the container surface. Before the arc clamping block 51 contacts the container surface, the sandpaper 74 contacts the container surface first, and then the clamping plate 1 and the clamping plate 2 3 are rotated to rotate the clamping plate 1 and the clamping plate 2 3 outside the container, so that the sandpaper 74 rotates and grinds the outer surface of the container. When the clamping plate 1 and the clamping plate 2 3 rotate outside the container, the rubber roller 77 can also rotate and drive the rotating rod 2 764 to rotate. The rotation of the rotating rod 2 764 drives the incomplete gear 763 to rotate, and the incomplete gear 763 rotates. The complete gear 763 rotates to drive the movable seat 761 to move left and right inside the slide 1 73. When the movable seat 761 moves left and right, the inclined flange 765 on one side of the movable seat 761 will contact different top blocks 766, thereby pushing different top blocks 766 to move in the direction of the sandpaper 74. The sandpaper 74 is supported by different top blocks 766, so that different areas of the sandpaper 74 are in contact with the container. After the grinding is completed, the screw 2 72 is rotated to make the slide 1 73 move back and reset, and then the locking screw 2 and the locking screw 76 are continued to be rotated. Rod 24 enables the sealing gasket 53 on the arc clamping block 51 to contact the surface of the container and the arc clamping block 51 can apply a clamping force to the container. Rotate the adjusting disk 545 and drive the screw 1 544 to rotate. The rotation of the screw 1 544 can drive the piston 543 to move in the hollow cavity 542. Adjusting the position of the piston 543 can change the pressure in the adsorption chamber 52. When a vacuum is formed in the adsorption chamber 52, additional adsorption force will be generated. Then, the lifting rope is tied to the two clamping plates 1 and 3, and the container is transferred by a crane.

[0036] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
