Description

Technical Field

[0001] This invention relates to a steel rolling conveyor device, and more specifically, to a steel rolling furnace exit roller conveyor frame structure. Background Technology

[0002] Currently, the furnace exit roller conveyors used in steel rolling production are designed as a split frame structure. The connection between the motor reducer and the frame roller conveyor is a drum-shaped gear coupling. Cooling water pipes are designed into the rollers, but since the water supply is not continuous, no drainage device is designed at the frame. This design has the following defects.

[0003] First, the independent frame has poor impact resistance and is easily affected by vibration, which seriously damages the anchor bolts.

[0004] Secondly, because the frame was not designed with a drainage system, the cooling water was directly discharged onto the ground, which could easily cause corrosion of the frame and anchor bolts.

[0005] Third, the connection between the motor reducer and the rollers used in the frame design is a rigid transmission connection, which does not take into account impact and vibration reduction functions. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a frame structure for a steel rolling mill exit roller conveyor, which can effectively improve the seismic resistance of the frame structure, effectively reduce the damage to the anchor bolts, and also reduce the corrosion of the frame structure foundation and anchor bolts by cooling water; at the same time, by reserving the installation position of the flexible transmission mechanism, the vibration impact on the roller conveyor is reduced, thus providing better protection for it.

[0007] The present invention discloses a steel rolling mill exit roller frame structure, comprising a frame body, wherein the frame body is provided with multiple roller mounting positions, and a return water collection box for collecting cooling water discharged from the roller is fixedly provided on one side of the frame body of each roller mounting position, and an extension seat for matching the flexible transmission mechanism between the roller and the reducer is provided on the other side of the frame body of each roller mounting position, wherein a mounting platform is fixedly provided at the end of the extension seat.

[0008] As a further improvement, the frame includes two symmetrically arranged main rods, with multiple connecting rods fixed between the two main rods; all the return water collection boxes are divided into two groups, and the two groups of return water collection boxes are staggered; all the extension seats are divided into two groups, and the two groups of extension seats are staggered.

[0009] Furthermore, the first set of return water collection boxes is fixedly installed on the side wall of one end of one of the main rods, and the second set of return water collection boxes is fixedly installed on the side wall of the other main rod away from the end of the first set of return water collection boxes.

[0010] Furthermore, the first set of extension seats is fixedly installed on the side wall of one end of one of the main rods, and the second set of extension seats is fixedly installed on the side wall of the other main rod away from the end of the first set of extension seats.

[0011] Furthermore, the connecting rod is misaligned with the roller conveyor mounting position.

[0012] Furthermore, a plurality of reinforcing support plates are fixedly installed between the two main rods, and the reinforcing support plates are located above the main rods in a corresponding manner.

[0013] As a further improvement, thickened plates are provided at both ends of the roller conveyor mounting position, and the thickened plates are fixedly installed on the main rod.

[0014] As a further improvement, a water inlet is provided on the top of the water return collection box, and a drain bolt is screwed onto the bottom of the water return collection box.

[0015] Furthermore, the end of the drain bolt is provided with a water channel extending along its axial direction. The water channel does not penetrate the drain bolt. A drain bolt corresponding to the bottom position of the water channel is provided with a discharge hole that communicates with the water channel. Multiple water inlet holes are provided on the drain bolt between the discharge hole and the end of the drain bolt.

[0016] As a further improvement, the extension base includes a base plate and two L-shaped reinforcing plates fixedly installed on the base plate; the main rod is made of channel steel, the base plate is fixed on the main rod, one end of each of the two L-shaped reinforcing plates is inserted into the groove of the main rod, and the end of the L-shaped reinforcing plate inserted into the groove of the main rod matches the groove; the ends of the two L-shaped reinforcing plates away from the main rod are jointly fixed to the mounting platform.

[0017] Beneficial effects

[0018] The advantages of this invention are:

[0019] 1. Setting multiple roller conveyor mounting positions on an integrated frame can effectively improve the seismic resistance of the frame structure and enhance its anchor bolt fixing capacity, thereby effectively reducing the damage to the anchor bolts.

[0020] 2. A return water collection box is fixed on one side of the frame at each roller conveyor installation position to collect the cooling water discharged from the roller conveyor, which can reduce the corrosion of the frame structure foundation and anchor bolts by the cooling water.

[0021] 3. By setting up the extension seat, the motor and reducer are moved outward, reserving an installation position for the flexible transmission mechanism. Compared with the traditional drum-shaped gear coupling structure, the vibration and impact on the roller conveyor are reduced, providing better protection for it.

[0022] 4. A drain bolt is installed at the bottom of the return water collection box, and a water channel, inlet hole and outlet hole are set in the drain bolt. This allows the water to be drained from the return water collection box without having to completely remove the drain bolt from the return water collection box, making the operation simpler and more convenient.

Detailed Implementation

[0030] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0031] See Figures 1-6 This invention discloses a steel rolling mill exit roller conveyor frame structure, comprising a frame body. The frame body has multiple roller conveyor mounting positions 2 for mounting rollers. Both ends of each roller conveyor mounting position 2 are provided with thickened plates 3, which are welded to the main rod 1. The thickened plates 3 effectively improve the rigidity of the roller conveyor mounting positions 2, thereby enhancing their support capacity.

[0032] Each roller conveyor installation position 2 has a return water collection box 6 fixed on one side of the frame to collect the cooling water discharged from the roller conveyor, which can reduce the corrosion of the frame structure foundation and anchor bolts by the cooling water.

[0033] Specifically, a water inlet 9 is provided on the top of the return water collection box 6, and a drain bolt 10 is screwed onto the bottom of the return water collection box 6. When it is necessary to drain the water in the return water collection box 6, simply turn the drain bolt 10 to open the drain port at the bottom of the return water collection box 6.

[0034] Since the drain bolt 10 is located at the bottom of the return water collection box 6, it is not easy to screw it back onto the return water collection box 6 after it is removed. Therefore, the present invention has made corresponding improvements to the drain bolt 10. Specifically, a water channel 11 extending along its axial direction is opened at the end of the drain bolt 10. The water channel 11 does not penetrate the drain bolt 10. A discharge hole 12 connected to the water channel 11 is opened on the drain bolt 10 corresponding to the bottom position of the water channel 11. Multiple water inlet holes 13 are opened on the drain bolt 10 between the discharge hole 12 and the end of the drain bolt 10. When draining water, it is only necessary to screw out the discharge hole 12 and expose it to the bottom of the return water collection box 6. The water in the return water collection box 6 can enter the water channel 11 through the water inlet holes 13 and be discharged from the discharge hole 12. It is not necessary to completely remove the drain bolt 10 from the return water collection box 6, making the operation simpler and more convenient. The setting of multiple water inlet holes 13 is conducive to more thoroughly emptying the water in the return water collection box 6.

[0035] On the other side of the frame at each roller conveyor mounting position 2, there is an extension seat 7 for matching the flexible transmission mechanism between the roller conveyor and the reducer. A mounting platform 8 is fixed at the end of the extension seat 7 for mounting the motor and reducer. The flexible transmission mechanism can be a belt conveyor or a chain drive mechanism. This invention moves the motor and reducer outwards, reserving a mounting position for the flexible transmission mechanism, thus reducing the vibration and impact on the roller conveyor and providing a certain degree of protection.

[0036] The frame in this embodiment includes two symmetrically arranged main poles 1, which are made of channel steel. Multiple connecting rods 4 are fixedly installed between the two main poles 1, achieving an overall frame structure design. Multiple reinforcing support plates 5 are fixedly installed between the two main poles 1, and each reinforcing support plate 5 is positioned above the main pole 1, effectively increasing the strength of the frame and making the supporting force of the frame structure stronger. The connecting rods 4 are staggered from the roller conveyor mounting positions 2 to avoid interference between the reinforcing support plates 5 and the roller conveyor.

[0037] To improve the horizontal balance of the frame structure, all the return water collection boxes 6 in this invention are divided into two groups, and the two groups of return water collection boxes 6 are staggered; all the extension seats 7 are also divided into two groups, and the two groups of extension seats 7 are staggered. That is, the return water collection boxes 6 and the extension seats 7 are respectively installed on two main rods 1, and the cross arrangement makes the gravity on both sides of the frame structure equal, thereby achieving the purpose of improving the horizontal balance of the frame structure.

[0038] Specifically, the first set of return water collection boxes 6 is fixedly installed on the side wall of one end of one of the main rods 1, and the second set of return water collection boxes 6 is fixedly installed on the side wall of the other main rod 1 away from the first set of return water collection boxes 6. The first set of extension seats 7 is fixedly installed on the side wall of one end of one of the main rods 1, and the second set of extension seats 7 is fixedly installed on the side wall of the other main rod 1 away from the first set of extension seats 7.

[0039] The extension base 7 of the present invention includes a base plate 14 and two L-shaped reinforcing plates 15 fixedly mounted on the base plate 14. The base plate 14 is fixed to the main rod 1, and one end of each of the two L-shaped reinforcing plates 15 is inserted into a groove in the main rod 1, with the end of the L-shaped reinforcing plate 15 inserted into the groove matching the groove; the ends of the two L-shaped reinforcing plates 15 away from the main rod 1 are jointly fixed to the mounting platform 8. This arrangement effectively improves the reliability of the installation of the extension base 7.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
