Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel rolling equipment assembly, and concretely relates to an auxiliary rotating device for roll box and cone box assembly, especially for the cone box with triangular outer contour. BACKGROUND

[0002] In the steel rolling process, the roll box and the cone box as the key equipment, the internal parts are easy to wear due to long time bearing high strength rolling force, and need to be regularly offline for part replacement, assembly and maintenance. In view of the fact that such equipment has very high precision, the requirement for assembly process is very strict.

[0003] The outer contour of the roll box and the cone box is triangular, and the structural characteristics make it necessary to place the equipment horizontally during assembly. However, due to the overall conical shape of the equipment, it is difficult to place horizontally, and the two ends need to be supported by auxiliary pads and other devices, which not only increases the complexity of assembly, but also easily causes the cone box to tip over, thereby causing equipment scratching and wear, and even threatening the safety of assembly personnel.

[0004] In summary, the existing method has the following difficulties:

[0005] 1. The cone box has a triangular outer contour and a conical overall structure, and the two ends need to be raised for assistance when placed horizontally (temporary pads are used in the prior art), which results in poor stability and easy tipping, causing equipment scratching and even personnel injury;

[0006] 2. It depends on multiple lifting and turning, which is time-consuming and labor-intensive and has safety hazards;

[0007] 3. The cone box is difficult to fully expose all surfaces, and the dead angle parts cannot be thoroughly cleaned. SUMMARY

[0008] According to the above technical problems, a special roll cone box assembly auxiliary device is provided to solve the technical problems of poor stability, complicated operation and low safety during cone box assembly, and to realize fast rotating positioning, stable support and efficient maintenance.

[0009] The technical means adopted by the utility model are as follows:

[0010] A roll cone box assembly auxiliary device, comprising:

[0011] A square turnover frame welded by 100mm channel steel;

[0012] A support frame fixed between two triangular supports by two cross beams, and the bases of the two triangular supports are fixed by foundation bolts;

[0013] Two fan-shaped rotating plates are fixed below two parallel edges of the square turnover frame respectively, and are synchronously rotated and assembled with one end of the conical box rotating shaft through the shaft hole, and the other end of the conical box rotating shaft is assembled on the top of the triangular support through the spherical roller bearing;

[0014] The manual driving mechanism comprises a worm gear assembly and a hand wheel, the worm gear is fixed to the end of the protruding part of the conical box rotating shaft penetrating through the top of the triangular support, and the worm is installed on the outer side of the upper end of one of the triangular supports through the base. The purpose of this scheme is to establish a high-rigidity bearing structure and solve the problem of unstable support of traditional temporary base plate.

[0015] Further,

[0016] The inner ring of the spherical roller bearing is fastened to the outer side wall of the fan-shaped rotating plate through an M16 bolt, and the outer ring of the bearing is embedded in the bearing seat on the top of the triangular support. The purpose of this scheme is to realize low-resistance rotation of the rotating frame and reduce wear caused by long-term use.

[0017] Further,

[0018] The worm mounting base is provided with a radial adjusting bolt, and the end of the bolt abuts against the worm shaft sleeve to realize meshing gap adjustment. The purpose of this scheme is to compensate for the wear of the worm gear and worm and maintain transmission accuracy.

[0019] Further,

[0020] The inner side wall of the square turnover frame is bonded with an anti-skid rubber pad, and the rubber pad has a thickness of 5mm and a surface provided with cross anti-skid lines with a depth of 1mm. The purpose of this scheme is to increase the frictional resistance between the conical box and the rotating frame and prevent relative sliding.

[0021] Further,

[0022] A fan-shaped positioning plate is arranged below the fan-shaped rotating plate on the opposite side of the manual driving mechanism, equal-angle locking holes are formed in the edge of the fan-shaped positioning plate, and 15° indexing positioning is realized by cooperating with spring buckle steel pins. The purpose of this scheme is to realize multi-angle quick locking of the conical box and meet the requirements of specific assembly positions.

[0023] Further,

[0024] A lifting lug plate is welded on the top of the support frame. The purpose of this scheme is to standardize the lifting interface and avoid structural damage caused by temporary binding.

[0025] Further,

[0026] A non-slip rubber sleeve is sleeved outside the hand wheel at the end of the worm, and the surface of the rubber sleeve is provided with convex point textures. The purpose of this scheme is to enhance the operation feeling and prevent control errors caused by hand slipping.

[0027] The technical scheme realizes precise assembly and multi-angle maintenance of the heavy conical box through systematic design. The combined truss main frame is used, and the anti-overturning rigid matrix is formed by the reinforced composite structure cooperating with the pre-tightening anchor, so that the load stability is significantly improved. The precision indexing control is realized based on the worm and gear transmission module of the rotary drive system, and fine angle adjustment is supported, and the adjustment process is stable and controllable. The anti-slip module is designed by using the deformation energy absorption and friction reinforcement mechanism through the composite elastic material and surface structure, which effectively inhibits the risk of load deviation. The indexing locking mechanism integrates automatic centering and double mechanical limiting functions, ensuring positioning accuracy while realizing operation safety redundancy. The device supports multi-section overturning positioning, which can quickly complete the adjustment and locking of the whole angle of the conical box, significantly shortening the time-consuming body position transformation process of traditional lifting. The system is compatible with the standard lifting interface, and combined with the modular maintenance components, the assembly and maintenance processes can be quickly switched. Through structural optimization and protection design, the impact resistance and durability are enhanced to meet the complex working condition requirements, and the safe, efficient and precise assembly of heavy components is realized.

[0028] Compared with the prior art, the utility model has the following advantages:

[0029] 1. Time-saving and labor-saving assembly process: using the rotary device of the application for conical box assembly can significantly save assembly time and reduce the physical burden of operators. Through the rotary device, the conical box can be easily adjusted to the best assembly position without frequent moving or overturning, thereby greatly improving the assembly efficiency.

[0030] 2. Improve the safety of assembly personnel: the design of the rotary device fully considers the safety needs of the operating personnel. By firmly fixing the conical box and allowing it to rotate 360 degrees, the risk of equipment tipping or sliding during assembly is effectively prevented, and safety accidents such as bruising are avoided, providing a safer and more reliable working environment for assembly personnel.

[0031] 3. Comprehensive cleaning and maintenance: the 360-degree rotation function not only facilitates assembly work, but also makes the cleaning and maintenance of the conical box more thorough. The operator can easily rotate the conical box to thoroughly check and clean dirt such as oil stains and dust, ensuring that the conical box always maintains the best working condition.

[0032] 4. Reduce production cost: by reducing repeated operations such as lifting and overturning, the rotary device of the application significantly reduces production cost. In the traditional assembly method, the conical box needs to be lifted and overturned multiple times to complete the assembly, which not only consumes time and effort, but also increases the risk of equipment damage. The use of the rotary device of the application can effectively avoid these problems, thereby reducing production cost and improving the economic benefit of the enterprise.
