Description

Technical Field

[0001] The utility model relates to the technical field of grinding roller carts, in particular to a grinding roller hoisting cart which is convenient for hoisting. Background Art

[0002] In the existing process of hoisting grinding rollers, the commonly used cart design usually places the grinding rollers in a parallel state. However, there are some problems with this arrangement. First, when the grinding rollers are placed in parallel, the distance between the two ends of the grinding rollers will be relatively close, especially when the grinding rollers are long or there are a large number of them. This compact arrangement is prone to cause collisions between the hoisting fixture and the grinding rollers during the hoisting process, increasing the risk and complexity of the hoisting operation.

[0003] Secondly, due to the close distance between the two ends of the grinding roller, the hoisting fixture needs to be frequently adjusted in position and angle during the hoisting process to adapt to the spacing between different grinding rollers. This not only reduces the hoisting efficiency, but also increases the labor intensity and difficulty of the operator. Utility Model Content

DETAILED DESCRIPTION

[0023] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A grinding roller lifting trolley for easy lifting comprises a trolley body 1, a bottom plate 2 is fixedly installed on the outer surface of the top of the trolley body 1, and side plates 3 are fixedly installed on both sides of the bottom plate 2, multiple groups of limit plates 5 are fixedly installed between the side plates 3, and the outer surfaces of the multiple groups of limit plates 5 are all provided with U-shaped through grooves, multiple groups of grinding rollers 4 are movably installed between the multiple groups of limit plates 5, and two groups of outer shells 6 are fixedly installed on the outer surfaces of the multiple groups of limit plates 5, two groups of fixed seats 611 are fixedly installed on the inner walls of the two groups of outer shells 6, and the outer surfaces of the two groups of fixed seats 611 are all provided with circular through grooves, a screw rod 612 is movably installed in the circular through groove, and one end of the screw rod 612 is connected to a motor 615, and a push rod 7 is movably installed on the outer surface of the screw rod 612.

[0026] Furthermore, a protective plate 613 is fixedly mounted on the outer surface of one side of the two sets of fixing bases 611 to prevent dust, debris or other impurities from entering between the fixing bases 611 and the housing 6, thereby maintaining its cleanliness and normal operation.

[0027] Furthermore, the fixing base 611 is fixedly connected to the motor 615 , and the fixed connection ensures the stability and reliability of the motor 615 , and reduces the risk of damage thereof due to vibration or shaking.

[0028] Furthermore, two sets of slide grooves are provided on the outer surface of one side of the push rod 7, and the inner walls of the two sets of slide grooves are engaged with a limiting slide rail 614. One side of the limiting slide rail 614 is fixedly connected to the limiting plate 5. The limiting slide rail 614 ensures the stable movement of the push rod 7 on the screw rod 612 and prevents the push rod 7 from deflecting or shaking during the movement.

[0029] Furthermore, a fixing plate 8 is fixedly installed on the top outer surface of the base plate 2, and a plurality of first connecting plates 912 are fixedly installed on the top outer surface of the fixing plate 8, a damper 9 is fixedly installed on the outer surface of one side of the plurality of first connecting plates 912, and one end of the damper 9 is connected to a second connecting plate 914, and one side of the second connecting plate 914 is connected to a support plate 911, and the coordinated use of the damper 9 and the spring 913 can provide buffering and shock absorption during the hoisting process, thereby preventing damage to the grinding roller 4 or the cart body 1 caused by the impact force generated during the hoisting process.

[0030] Furthermore, a spring 913 is connected between the first connecting plate 912 and the second connecting plate 914, and the spring 913 can provide buffering and shock absorption during the hoisting process. When the grinding roller 4 is hoisted or placed, a certain impact or vibration may be generated, and the spring can effectively absorb the impact force, thereby protecting the cart body 1 and other components from damage.

[0031] Furthermore, the U-shaped groove on the outer surface of the limit plate 5 is wrapped with rubber. The rubber material has good elasticity and wear resistance, and can form a protective layer between the grinding roller 4 and the limit plate 5, effectively preventing the grinding roller 4 from being scratched by the limit plate 5 during placement or movement, thereby protecting the surface of the grinding roller 4 from damage.

[0032] Working principle: When using the grinding roller lifting trolley that is easy to lift to perform the lifting operation of the grinding roller 4, first ensure that multiple groups of grinding rollers 4 are placed between multiple groups of limiting plates 5 through the U-shaped through grooves at both ends of them, and maintain their initial parallel state. When lifting is required, by starting the motor 615, the motor 615 drives the screw rod 612 to rotate. The outer surface of the screw rod 612 cooperates with the threaded structure provided inside the push rod 7, so that the push rod 7 can move along the axial direction of the screw rod 612. As the push rod 7 moves, its end will contact and push one end of the grinding roller 4 to move upward. Since multiple groups of grinding rollers 4 are movably installed between the limiting plates 5 through the U-shaped through grooves at both ends, the other end of the grinding roller 4 will also move upward accordingly with the push of the push rod 7, so that both ends of the grinding roller 4 are lifted and the grinding rollers 4 are no longer kept in a parallel state. When the grinding roller 4 is lifted to a certain height so that the distance between its two ends is large enough, the lifting fixture can easily clamp the two ends of the grinding roller 4, thereby facilitating the lifting operation. In this way, the collision between the lifting fixture and the grinding roller 4 is effectively avoided, the number of adjustments of the lifting fixture is reduced, and the lifting efficiency and safety are improved.
