[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3The utility model provides a technical solution: a crane with an auxiliary limiting structure, including a crane body 1, a base 2 is provided at the bottom end of the crane body 1, and the base 2 is connected to the bottom end of the crane body 1 by welding. The base 2 is a circular structure and rollers are provided on both sides of the bottom. The rollers are equipped with a basic roller locking mechanism. Strip grooves 3 are provided on both sides of the top of the base 2. The inside of the strip groove 3 is provided with a reversible positioning strip 4. One end of the positioning strip 4 is connected to the inner wall of the strip groove 3 on the outside through an axle rod. A screw ring 7 is provided inside the outer end of the positioning strip 4 through a perforation. A support column 5 is detachably installed inside the screw ring 7. The outer wall of the upper end of the support column 5 is provided with a threaded structure at one end. The bottom end of the support column 5 is welded An auxiliary support block 6 is fixed, and the front side of the screw ring 7 is connected to the positioning strip plate 4 through the rotating shaft 8. A fixed ring 13 for limiting the rotating shaft 8 is welded and fixed to the front side of the outer end of the positioning strip plate 4. When the crane body 1 of this structure is moved to a suitable use position through the rollers on the base 2, the positioning strip plate 4 can be flipped out from the inside of the strip groove 3 and placed on both sides of the base 2. At this time, the support column 5 can support the auxiliary support block 6 on the ground by connecting the upper end to the inside of the screw ring 7, and the screw ring 7 can also be rotated on the positioning strip plate 4 through the rotating shaft 8 to adjust the left and right inclination angles of the support column 5 and the auxiliary support block 6 when supported. The auxiliary support block 6 can adapt to the support on the uneven ground to play an auxiliary limiting role on the base 2, thereby achieving the effect of strengthening the locking of the base 2. The effect is to avoid the problem of displacement of the base 2 caused by the vibration and external vibration during operation of the crane body 1, thereby improving the stability and safety of the crane body 1 during operation. The outer end of the shaft 8 penetrates to the outside of the front side of the positioning strip 4 and forms a sliding connection with the connection of the positioning strip 4, and the fixing ring 13 is located outside the outer end of the shaft 8. A screw barrel 14 is welded and fixed on the outer wall of the outer end of the shaft 8, and a screw pin 15 is inserted into the interior of the screw barrel 14 through a threaded structure, and a plurality of fixing holes that match the screw pin 15 structure are evenly arranged on the inner wall of the fixing ring 13. When the shaft 8 of this structure is adjusted to a suitable angle position by rotating in the positioning strip 4, the screw pin 15 can rotate inside the screw barrel 14 to adjust the outer end The screw shaft 10 is fixed in the corresponding fixing hole on the inner wall of the fixing ring 13, so that the rotating shaft 8 can synchronously lock the supporting angle of the support column 5 and the auxiliary support block 6 after limiting the position of the screw ring 7, thereby ensuring the stability of the support column 5 and the auxiliary support block 6 when they are supported on the ground. The outer walls of both sides of the base 2 are welded and fixed with screw sleeves 9, and the interior of the screw sleeves 9 is interspersed with screw shafts 10 through a threaded structure, and the inner end of the positioning strip 4 is provided with a locking hole that matches the structure of the screw shaft 10. When the positioning strip 4 of this structure is flipped out from the inside of the strip groove 3, the screw shaft 10 can be fixed to the locking hole on the positioning strip 4 by rotating inside the screw sleeve 9, so as to achieve the function of limiting the positioning strip 4, and further ensure the stability of the positioning strip 4 when used in conjunction with the support column 5 and the auxiliary support block 6.The outer end of the positioning strip 4 is bonded and fixed with an elastic block 12 made of rubber material, and the inner wall of one side adjacent to the strip groove 3 is provided with an embedding groove that matches the structure of the elastic block 12. When the positioning strip 4 of this structure is recycled, the elastic block 12 can be squeezed into the embedding groove on the inner wall of the strip groove 3 to ensure the stability of the positioning strip 4 when it is stored. The inner walls of the front and rear sides of the base 2 are provided with a storage groove 11 with a variable diameter structure, and the inner end part of the storage groove 11 matches the structure of the support column 5. When not in use, the support column 5 and the auxiliary support block 6 of this structure can be directly inserted into the storage groove 11 for easy storage, which is more convenient to use.
[0018] Working principle: When using the crane with the auxiliary limiting structure, first, when the crane body 1 is moved to a suitable use position through the rollers on the base 2, the rollers on the base 2 are first locked preliminarily through their own locking mechanism, and then the positioning strips 4 are flipped out from the inside of the strip groove 3 and placed on both sides of the base 2 until the positioning strips 4 are in a horizontal state, and then the screw shaft 10 is rotated inside the screw sleeve 9 so that the outer end is fixed in the locking hole on the positioning strip 4 to limit the positioning strip 4. At this time, the support column 5 is connected to the inside of the screw ring 7 through the upper end threaded structure so that the auxiliary support block 6 is supported on the ground. When the ground is uneven and the supporting angle of the auxiliary support block 6 needs to be adjusted, the screw ring 7 can be adjusted by rotating on the positioning strip 4 through the rotating shaft 8 until the auxiliary support block 6 is appropriately supported on the ground, and the screw pin 15 is rotated inside the screw barrel 14 until the screw pin 15 The outer end of the screw ring 7 is fixed in the corresponding fixing hole on the inner wall of the fixing ring 13, so that after the screw ring 7 is limited, the supporting angles of the support column 5 and the auxiliary support block 6 can be locked synchronously, and the auxiliary support block 6 can play an auxiliary limiting role on the base 2. When the crane body 1 is used up, the support column 5 is removed from the screw ring 7 in accordance with the above reverse order, and the support column 5 and the auxiliary support block 6 can be directly inserted into the storage groove 11 for storage, and the positioning strip plate 4 can be recycled by squeezing the elastic block 12 into the embedded groove on the inner wall of the strip groove 3 to stably recover it in the strip groove 3, thereby completing a series of work.
