[0027] Specifically, box 1 plays a protective and fixed effect to internal components, when length needs to be adjusted, first pull rod 15 is pulled to drive pawl 11 to release the engagement of ratchet gear 10, then manually rotate adjusting rod 2 to rotate in the inner wall of box 1, support structure is also arranged on the inner wall of box 1 to support the middle section of adjusting rod 2, when adjusting rod 2 rotates, the bevel gear 3 at the other end thereof rotates synchronously, engages with bevel gear 5, since bevel gear 5 is fixedly connected on rotating rod 4, so rotating rod 4 is driven to rotate, the main gear 6 fixedly connected on rotating rod 4 rotates, the rack rod 7 on the two sides of main gear 6 is driven to slide in opposite directions due to engagement, in turn drives baffle 8 to slide synchronously, thereby the length adjustment of box 1 is completed, the locking of length adjustment process of box 1 is realized through the one-way locking of ratchet and pawl, so as to ensure stability.

[0028] Referring to Figure 1 And Figure 6 The partition subassembly includes multiple slide rails 18, multiple The slide rails 18 are uniformly fixedly connected on the upper surface of the box 1, the inner wall of the slide rail 18 is slidably connected with multiple sliding blocks 19, the top end of the sliding block 19 is fixedly connected with partition plate 20, the top end of the partition plate 20 is fixedly connected with combination block 21, the inner wall of the two partition plates 20 is slidably connected with extension plate 22 on opposite sides.

[0029] Specifically, the steel pipes of different widths are adapted by the plurality of uniformly distributed sliding rails 18, a plurality of sliding blocks 19 are slidingly connected in the sliding rails 18 and can be freely disassembled, the partition plates 20 fixedly installed at the top ends of the sliding blocks 19 are used to form the partition of the steel pipes in the X-axis direction of the box body 1, the friction between the steel pipes is reduced to a certain extent, the shaking and tilting of the steel pipes are limited, the stability of the hoisting and transferring process is increased, and the partition length is increased by the extension plates 22 to adapt to steel pipes of different lengths.

[0030] With reference to Figure 5 , the bottom end of the box body 1 is provided with a counterweight groove 16, and a plurality of counterweight balls 17 are slidingly connected to the inner wall of the box body 1.

[0031] Specifically, when the box body 1 is hoisted, the shaking will make the steel pipes in the box body 1 unstable, the plurality of counterweight balls 17 are slidingly connected in the counterweight grooves 16 formed in the inner wall of the box body 1, and as the box body 1 shakes, the counterweight balls 17 are automatically distributed to the opposite direction of the shaking to balance the box body 1, offset the unbalanced moment, increase the weight of the box body 1, lower the center of gravity of the box body 1, and increase the stability.

[0032] With reference to Figure 5 , the top ends of the box body 1 and the baffle 8 are fixedly connected with a plurality of hoisting rings 23, and the bottom end of the box body 1 is provided with a plurality of forklift holes 24.

[0033] Specifically, after the steel pipes are loaded, the box body 1 can be hoisted by installing a hoisting rope in the hoisting ring 23, or the box body 1 can be transferred by using a forklift through the forklift holes 24.

[0034] With reference to Figure 2 and Figure 4 , the inner wall of the ratchet gear 10 is provided with a ratchet wheel, the pawl 11 is slidingly connected and engaged with the outer wall of the ratchet wheel, one end of the spring 13 is fixedly connected to the outer wall of the pawl 11, the other end of the spring 13 is fixedly connected to the outer wall of the fixed rod 12, and the pull rod 15 is slidingly connected and penetrates through the inner wall of the box body 1.

[0035] Specifically, the rotation direction of the ratchet gear 10 is limited by the one-way limiting of the ratchet wheel and the pawl, so as to limit the rotation direction of the main gear 6, so that when the rack rod 7 is extended, it will be engaged, preventing the length of the box body from continuing to increase after the steel pipes are loaded into the box body 1, so that the baffle 8 loses the limitation on the steel pipes, and the contraction of the rack rod 7 is not affected, because after the steel pipes are loaded, the ends of the steel pipes will block the contraction of the rack rod 7, thereby forming natural locking, when the box body 1 needs to be extended, the pawl 11 needs to be pulled away from the engagement with the ratchet wheel by pulling the pull rod 15, and the elastic force of the spring 13 ensures the reset of the pawl 11 when the pull rod 15 is loosened.

[0036] Referring to Figure 6 and Figure 7 The inner wall of the partition plate 20 is provided with a track groove, and one of the sliding blocks 19 is slidingly connected to the inner wall of the combined block 21.

[0037] Specifically, the sliding of the extension plate 22 is limited by the track groove, which also prevents the extension plate 22 from falling off during sliding, so that the extension plate 22 and the two partition plates 20 are connected to achieve the effect of extension and increase the limiting length of the steel pipe. By slidingly installing the sliding block 19 in the combined block 21, multiple partition plates 20 can be stacked up and down to increase the limiting height.

[0038] Referring to Figure 1 and Figure 6 The outer walls of the box body 1, the partition plate 20 and the extension plate 22 are fixedly connected with multiple protective pads 25.

[0039] Specifically, the protective pads 25 prevent the surface of the device from causing wear to the outer wall of the steel pipe during hoisting and transferring, and also prevent the steel pipe from rubbing against the box body 1, the partition plate 20 and the extension plate 22, thereby prolonging the service life of the device.

[0040] Working principle: when using the steel pipe hoisting and transferring equipment, first pull the pull rod 15 to make the pull rod 15 drive the pawl 11 to compress the spring 13 and slide away from the engagement with the ratchet gear 10, then manually rotate the adjusting rod 2 to drive the bevel gear 3 to rotate, which drives the bevel gear 5 to rotate through meshing, and the bevel gear 5 drives the rotating rod 4 to rotate and then drives the main gear 6 to rotate, which drives the two rack rods 7 on both sides to move in opposite directions through meshing, and the rack rod 7 drives the baffle 8 to slide synchronously when moving, thereby achieving the effect of adjusting the length of the box body. After adjusting according to the length of the steel pipe, slide the sliding block 19 at the bottom of the partition plate 20 along the slide rail 18 to the appropriate position, and according to the actual demand, pull out the internal extension plate 22 and stack multiple partition plates 20 in the slide groove of the combined block 21 at the top of the partition plate 20, thereby forming a partition in the box body. After placing the steel pipe in the middle of the multiple partition plates 20, install the hoisting rope in the hoisting ring 23 and then use the existing crane and other equipment for hoisting. During hoisting, the multiple counterweight balls 17 installed at the bottom of the box body 1 will slide in the counterweight groove 16 to balance the counterweight, and then the box body 1 can be transferred by a forklift through the forklift hole 24.
