Description

Technical Field

[0001] The utility model relates to the technical field of transport packaging protection, in particular to a packaging rack used for long-distance transportation of steel structural parts. Background Art

[0002] Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and other fields. Steel structures are mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and steel plates. They are connected by welds, bolts, or rivets to form the skeleton frame of wall beams, purlins, and other components. Currently, metal corrugated wall panels or rock wool sandwich panels are usually selected as exterior wall panels, which are combined at the construction site to form the external protective structure. With the rapid development of prefabricated buildings and steel structures and the increase in export projects, the export transportation of steel structures and sandwich panels requires multiple transfers and long-distance sea transportation. To ensure that the steel structures and sandwich panels do not deform during multiple transfers and long-distance transportation and to ensure transportation safety, the use of transport packaging and protective tooling is required. The existing steel structure transport packaging and protective tooling is not only of various types and specifications, but also has a Chinese patent document with publication number CN213385186U, which discloses a steel structure transport packaging and protective tooling, which includes a central lifting bracket and movable end frames on the left and right sides, which can enhance the protection of steel structure components. However, it has the following disadvantages in specific use: the lifting bracket is fixed, and the vertical beam and the connecting frame above it are integrated with the base. On the one hand, it is inconvenient to load and unload steel structure components onto the lifting bracket, which affects the speed of loading and unloading and has low work efficiency. On the other hand, since the vertical beam is integrated with the base, the height of the vertical beam is fixed, which cannot meet the loading needs of goods of different heights. The use range of the lifting bracket is limited and its practicality is poor. In addition, since the lengths of steel structure components vary during actual transportation, it is inconvenient to fix steel structure components of different lengths on the lifting bracket by tying ropes. Moreover, the tying ropes are prone to slide along the length direction of the lifting bracket, causing the steel structure components to be loosely fixed and easily move back and forth during long-distance transportation, which undoubtedly increases the unsafe factors during transportation and is inconvenient to use.

[0029] Example 5:

[0030] As attached Figure 4As shown, the difference between this embodiment and embodiments 1-4 is that the stand quick lock device 6 includes a left lock card half shell 11, a right lock card half shell 12, a left semi-conical slip 13, and a right semi-conical slip 14. The lower ends of the left lock card half shell 11 and the right lock card half shell 12 are respectively welded and fixed to the upper end of the chassis assembly 1 and spliced to form a cylinder. The interiors of the left lock card half shell 11 and the right lock card half shell 12 respectively have half-shell heart cavities. The side walls of the half-shell heart cavities of the left lock card half shell 11 and the right lock card half shell 12 are spliced to form an inner cone surface 15 of the shell, and the inner cone surface 15 of the shell is small at the top and large at the bottom. Conical surface, the upper ends of the left lock card half shell 11 and the right lock card half shell 12 are respectively provided with half shell top openings, the half shell top openings of the left lock card half shell 11 and the right lock card half shell 12 are spliced to form a vertical axial diameter hole 16, the lower end of the vertical axial diameter hole 16 is connected to the half shell heart cavity, the outer sides of the left semi-conical slip 13 and the right semi-conical slip 14 are spliced to form a slip outer conical surface 17 that can cooperate with the inner conical surface 15 of the shell body, the left semi-conical slip 13 and the right semi-conical slip 14 are sleeved in the half shell heart cavity of the left lock card half shell 11 and the right lock card half shell 12 through the slip outer conical surface 17 and can be turned to the left When the left and right half-cone slips 13 and 14 move upward, the inner sides of the left and right half-cone slips 13 and 14 are spliced together to form a cylindrical locking cavity 18. Coarse teeth 19 are provided on the side walls of the locking cavity 18. A compression spring 20 is installed at the lower part of the half-shell heart cavity below the left and right half-cone slips 13 and 14. The lower end of the compression spring 20 is tightly pressed against the upper end of the chassis assembly 1, and the upper end of the compression spring 20 is tightly pressed against the lower end surface of the left and right half-cone slips 13 and 14. A limiting bolt groove 21 is provided on the upper left part of the left locking half shell 11 and the right locking half shell 12. A bolt groove pin 22 is fixed on the left semi-conical cava 13 and the right semi-conical cava 14 at the left end position of the limit bolt groove 21, respectively. The bolt groove pin 22 can move downward along the limit bolt groove 21 and be fixed to its right end to realize the separation of the outer conical surface 17 of the cava from the inner conical surface 15 of the shell. The upper ends of the left semi-conical cava 13 and the right semi-conical cava 14 extend to the top of the left locking half shell 11 and the right locking half shell 12 through the vertical axial diameter hole 16 respectively to form a cava neck 23, and a cava handle 24 is fixed on the outside of the cava neck 23 of the left semi-conical cava 13 and the right semi-conical cava 14 respectively.

[0031] When it is necessary to unlock the stand quick lock device 6, the left half-cone slip 13 and the right half-cone slip 14 are grasped and pressed downward by the slip handles 24. The left half-cone slip 13 and the right half-cone slip 14 overcome the elastic force of the compression spring 20 and move downward. Then, the slip handle 24 is rotated to the right. The bolt groove pin 22 moves to the right along the limit bolt groove 21. The slip handle 24 drives the left half-cone slip 13 and the right half-cone slip 14 to turn right synchronously. Then, the slip handle 24 is pressed down again and the slip handle 2 is pulled to the right. 4, until the bolt groove pin 22 moves to the rightmost end of the limit bolt groove 21, and the outer conical surface 17 of the slip completely leaves the inner conical surface 15 of the shell, at this time, the coarse tooth teeth 19 on the side wall of the locking cavity 18 of the left semi-conical slip 13 and the right semi-conical slip 14 release the lock on the first frame column 202 or the second frame column 302, and the first U-shaped frame 2 and the second U-shaped frame 3 can be extracted by the lifting device; when the first U-shaped frame 2, the second U-shaped frame 3 and the base frame assembly 1 are assembled , use the sling to drop the first U-shaped stand 2 and the second U-shaped stand 3, and install the first frame column 202 or the second frame column 302 into the locking cavity 18 formed by the left semi-cone slip 13 and the right semi-cone slip 14. When it is necessary to lock the stand quick lock device 6, the left semi-cone slip 13 and the right semi-cone slip 14 can be driven to turn left by pulling the slip handle 24, and the compression spring 20 pushes the left semi-cone slip 13 and the right semi-cone slip 14 to move upward, and at the same time the bolt groove pin 22 moves along the limit bolt groove 21 moves upward, then continues to lift and turn the slip handle 24 to the left. When the bolt groove pin 22 moves to the uppermost end of the limit bolt groove 21, the lower portions of the left and right semi-conical slips 13 and 14, under the action of the inner conical surface 15 of the shell, reduce the inner diameter of the locking cavity 18. The coarse teeth 19 on the side walls of the locking cavity 18 clamp the outer surface of the first frame column 202 or the second frame column 302, ultimately achieving reliable locking of the first frame column 202 or the second frame column 302. According to actual needs, by replacing the left and right semi-conical slips 13 and 14 in the stand quick lock device 6 and selecting slips with locking cavities 18 of different inner diameters, it is possible to adapt to stand columns of different diameters and strengths to meet the actual needs of loading different goods, further improving the applicability of the present utility model.

[0032] Example 6:

[0033] As attached Figure 4As shown, the difference between this embodiment and embodiments 1-5 is that the limiting bolt groove 21 is W-shaped and includes a left vertical section 211, an upper horizontal section 212, a right vertical section 213, and a lower horizontal section 214. The lower end of the left vertical section 211 is connected to the left end of the upper horizontal section 212, the right end of the upper horizontal section 212 is connected to the upper end of the right vertical section 213, and the lower end of the right vertical section 213 is connected to the left end of the lower horizontal section 214. The length of the left vertical section 211 is smaller than the length of the lower horizontal section 214. The upper horizontal section 212, the right vertical section 213, and the lower horizontal section 214 can buffer the movement speed of the bolt pin 22 in the limiting bolt groove 21, avoiding accidental loss caused by sudden unlocking, making locking safer and more reliable, and also preventing the bolt pin 22 from slipping out of the limiting bolt groove 21 due to accidental vibration, thereby improving safety performance.

[0034] Example 7:

[0035] As attached Figure 4 As shown, the difference between this embodiment and embodiments 1-6 is that the taper of the inner conical surface 15 of the housing is 1:12 to 1:16. If the taper of the inner conical surface 15 of the housing is too small, it will cause self-locking. When subjected to a large load, the left and right half-cone slips 13 and 14 will become stuck in the inner conical surface 15 of the housing. If the taper is too large, the upper diameter of the left and right half-cone slips 13 and 14 will be too small, which will not only affect the strength of the slip neck 23, but also affect the strength of the locking force of the stand quick lock device 6 on the first frame column 202 or the second frame column 302, causing slipping due to poor or insecure locking. After actual test comparison, the taper of the inner conical surface 15 of the shell is preferably 1:14. At this time, the taper of the left half-cone slip 13 and the right half-cone slip 14 is most appropriate, which can not only clamp the first frame column 202 or the second frame column 302 without damaging the first frame column 202 or the second frame column 302, but also ensure that the left half-cone slip 13 and the right half-cone slip 14 can be smoothly removed after bearing a large tonnage load and entering the left locking half shell 11 and the right locking half shell 12.

[0036] Example 8:

[0037] As attached Figure 1 、 25, the difference between this embodiment and embodiments 1-7 is that the left adjustable frame 9 includes an adjustable frame front rod, an adjustable frame rear rod and an end baffle, the adjustable frame front rod is sleeved on the left end of the chassis front side beam 101, the adjustable frame rear rod is sleeved on the left end of the chassis rear side beam 102, the front and rear ends of the end baffle are respectively welded and fixed to the left end of the adjustable frame front rod and the left end of the adjustable frame rear rod, the left and right ends of the chassis front side beam 101 and the chassis rear side beam 102 are respectively provided with a locking bolt fixing hole 25, and the adjustable frame front rod corresponding to the position of the locking bolt fixing hole 25 is A set of adjustment bolt holes is provided on each of the front and rear rods of the adjustable frames. The adjustment bolt holes include at least two adjustment bolt holes 26 spaced apart. The front and rear rods of the adjustable frames are secured to the locking bolt fixing holes 25 at the left ends of the front and rear side beams 101, 102 of the chassis via the adjustment bolt holes 26 and locking bolts, respectively. The right adjustable frame has the same structure as the left adjustable frame 9. The right adjustable frame is secured to the locking bolt fixing holes 25 at the right ends of the front and rear side beams 101, 102 of the chassis via locking bolts.
