[0002] Steel production technology generally adopts continuous steel casting technology, which requires that the billet must be cut to a fixed length when it comes off the line, and the cut head must be square and not deformed. Hydraulic shears are equipment used to cut the billet to a fixed length after it is formed. The hydraulic shears include a shearing device, a mobile frame, a track frame, a traveling mechanism and a power cylinder. The traveling mechanism is installed on the mobile frame, the mobile frame is installed on the track frame, and the shearing device is installed on the mobile frame. The mobile frame drives the shearing device to move on the track frame under the drive of the power cylinder to achieve the translation of the hydraulic shears.

[0003] In the related art, due to the heavy weight of the shearing device, the movable frame generates a large friction force under the drive of the oil cylinder. In this way, the movable frame is also subjected to large force, and the movable frame has low strength and is easy to deform, thereby causing the oil cylinder ear seat on the movable frame to deform accordingly, resulting in the oil cylinder stroke failing to meet the requirements, causing the entire shearing device to swing greatly during operation, thereby affecting the shearing effect.

[0004] In view of this, it is necessary to propose a steel billet hydraulic shear mobile frame to solve the above defects. Utility Model Content

[0026] Please refer to Figure 1 and Figure 2The utility model provides a billet hydraulic shear mobile frame. The billet hydraulic shear mobile frame comprises a bottom plate 1, two side plates 3, an intermediate support frame 5, an edge support plate 6, a cylinder ear seat 7 and a reinforcing structure 9, wherein the two side plates 3 are arranged at intervals relative to each other, the bottom plate 1 is fixedly arranged between the two side plates 3 and is located at the bottom of the two side plates 3, an installation space is enclosed between the bottom plate 1 and the two side plates 3, the intermediate support frame 5 is fixed in the installation space and fixedly connected between the two side plates, the edge support plate 6 is fixed in the installation space and fixed between the two side plates 3, the intermediate support frame 5 and the edge support plate 6 are respectively arranged in the middle and at both ends of the side plates 3, the intermediate support frame 5 is located between the edge support plates 6 and is spaced apart from each other, the cylinder ear seat 7 is fixedly connected to one of the edge support plates 6, and the reinforcing structure 9 is fixedly connected to the cylinder ear seat 7 and the edge support plate 6. By setting the intermediate support frame 5 in the middle of the side plate 3 and setting the side support plate 6 at both ends of the side plate 3, the two side plates 3 arranged at intervals are supported and fixed, thereby improving the overall strength of the mobile frame. By fixing the reinforcing structure 9 between the cylinder ear seat 7 and the side support plate 6, the strength of the cylinder ear seat 7 is increased. On the basis of the increase in the overall strength of the mobile frame, the strength of the cylinder ear seat 7 is increased by the reinforcing structure 9, thereby greatly improving the strength of the cylinder ear seat 7. Therefore, by setting the intermediate support frame 5, the side support plate and the reinforcing structure 9, the structural strength of the mobile frame is greatly improved, and the strength of the cylinder ear seat 7 is also improved, thus avoiding the problem of low strength of the cylinder ear seat 7 due to low overall strength of the mobile frame in the prior art. During the driving process, the cylinder will not affect the shearing effect due to excessive swing amplitude of the shearing device.

[0027] See also Figure 2 Specifically, the intermediate support frame 5 is fixed in the middle position of the two side panels and is located at the top position. There are multiple intermediate support frames 5, and the multiple support frames are respectively fixedly connected between the two side panels 3 at intervals. Preferably, in this embodiment, there are two intermediate support frames 5, and the two support frames are fixed on the side panels to strengthen the connection and fixation of the two side panels.

[0028] Furthermore, the intermediate support frame 5 includes a transverse plate 51 and a longitudinal plate 53 which are simultaneously connected to the two side plates 3, the longitudinal plate 53 is vertically fixed under the transverse plate 51, and the transverse plate 51 and the longitudinal plate 53 are arranged along the spacing direction between the two side plates 3 to strengthen the connection strength between the two side plates.

[0029] Furthermore, the transverse plate 51 and the longitudinal plate 53 of the intermediate support frame 5 are arranged in a T-shape. It can be understood that the T-shape arrangement can greatly improve the strength of the intermediate support frame 5 itself, thereby improving the connection strength between the two side plates 3.

[0030] Specifically, the oil cylinder lug seat 7 comprises two fixed plates 71 arranged at a relative interval, the fixed plates 71 are provided with mounting holes 73, a shaft sleeve 75 is installed in the mounting hole 73, a pin 77 is assembled in the shaft sleeve 75, and the oil cylinder is connected to the pin 77. The fixed plates 71 are fixed to the edge support plate 6, and the oil cylinder is connected to the shaft sleeve 75 through the pin 77. By installing the shaft sleeve 75 in the mounting hole 73, the wear resistance of the mounting hole 73 is improved to reduce the maintenance frequency, and the replacement only needs to replace the shaft sleeve 75, which is also convenient. In the prior art, the connecting shaft of the oil cylinder piston is directly assembled in the mounting hole 73, which makes the oil cylinder lug seat 7 easy to wear, and the replacement requires the replacement of the entire mobile frame. The present application solves the problem of direct wear of the oil cylinder lug seat 7 by assembling the shaft sleeve 75 in the mounting hole 73 of the oil cylinder lug seat 7.

[0031] Specifically, the reinforcing structure 9 is connected to the side support plate, the cylinder ear seat 7 and the side plate at the same time. The reinforcing structure 9 includes a transverse reinforcing rib 91 and a longitudinal reinforcing rib 93. The transverse reinforcing rib 91 is fixedly connected to the side plate 3, the cylinder ear seat 7 and the edge support plate 6, and the longitudinal reinforcing rib 93 is connected to the transverse reinforcing rib 91 and the edge support plate 6, which increases the connection strength of the side support plate, the cylinder ear seat 7 and the side plate, making the structural stability of the cylinder ear seat 7 better and not easy to deform. In this way, the cylinder can also meet the requirements in terms of movement stroke, and will not cause the shearing device to swing too much.

[0032] See also Figure 3 Further, the transverse reinforcing ribs 91 and the longitudinal reinforcing ribs 93 are arranged in a T-shape. It can be understood that the T-shaped reinforcing structure 9 has a higher strength, which strengthens the strength of the cylinder ear seat 7.

[0033] In addition, the spray water for cooling the hydraulic shear body and the oil pipe will enter the mobile frame, resulting in water accumulation in the mobile frame, which in turn causes the mobile frame to rust and corrode. Therefore, the side plate 3 is provided with a plurality of drainage holes 13 penetrating the left and right sides thereof, and the plurality of drainage holes 13 are connected to the installation space, and the accumulated water is discharged through the drainage holes 13. Moreover, in order to prevent the accumulated water from directly pouring onto the steel billet when being discharged, organized drainage is adopted. Specifically, two drainage holes are provided on each of the side plates.

[0034] Specifically, the side panel 3 and the bottom panel 1, the middle support frame 5 and the side panel 3, the edge support plate 6 and the side panel 3, the reinforcing structure 9 and the side panel 3, the cylinder ear seat 7 and the edge support plate 6 are all fixed by welding to improve the connection performance between the side panel, the bottom panel 1, the middle support frame 5, the edge support plate 6 and the reinforcing structure 9.

[0035] The steel billet hydraulic shear moving frame provided by the utility model arranges the intermediate support frame 5 in the middle of the side plate 3, and arranges the side support plates 6 at both ends of the side plates 3, so that the two side plates arranged at intervals are supported and fixed, thereby improving the overall strength of the moving frame, and the reinforcing structure 9 is fixedly connected between the cylinder ear seat 7 and the side support plate 6, so that the strength of the cylinder ear seat 7 is increased. On the basis of the increased overall strength of the moving frame, the strength of the cylinder ear seat 7 is increased by the reinforcing structure 9, thereby greatly improving the strength of the cylinder ear seat 7.
