Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metal rolling, and particularly relates to an auxiliary supporting device for a multiple-length round steel extraction trolley. Background Art
[0002] In the process of bar production, multiple-length round steel is transported from the cooling bed to the front-shearing roller table by multiple extraction trolleys arranged at intervals of 1.5 m and lifted horizontally at the same time. The front-shearing roller table is connected to a fixed-length shearing machine for subsequent fixed-length shearing. The currently used extraction trolleys are arranged on a supporting beam at the same time. When producing small-diameter round steel, due to the simultaneous lifting of multiple extraction trolleys, the supporting beam bears the weight evenly, and the bearing capacity of the supporting beam can meet the requirements.
[0003] However, when transporting large-diameter round steel, since the self-weight per unit length of the large-diameter multiple-length round steel is greater and the multiple length is shorter, the pressure on a single extraction trolley is doubled, posing higher requirements for the bearing capacity of the bearing beam. In order to improve the bearing capacity of the extraction trolley, an auxiliary supporting device for a multiple-length round steel extraction trolley is proposed. Content of the Utility Model
[0004] Aiming at the problems existing in the prior art, the utility model provides an auxiliary supporting device for a multiple-length round steel extraction trolley.

[0007] A guiding wheel is rotatably connected in the supporting cover, and the guiding wheel is supported on the auxiliary supporting beam and rolls along the auxiliary supporting beam.
[0008] Further, an auxiliary supporting beam guide rail is arranged axially in the middle of the top surface of the auxiliary supporting beam, the guiding wheel is arranged as a concave wheel, and the concave part of the guiding wheel straddles the auxiliary supporting beam guide rail to guide the rolling direction of the guiding wheel.

[0020] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0021] Referring to Figure 1 , an auxiliary support device for a multiple-length round steel extraction trolley. The auxiliary support device is arranged above the support beam 9 of the extraction trolley 10 and includes an auxiliary support beam 1. The auxiliary support beam 1 is suspended above the support beam 9 and is placed along the moving direction of the extraction trolley 10.
[0022] A support cover 8 is buckled on the auxiliary support beam 1. The support cover 8 is a U-shaped structure formed by bending or welding high-strength steel plates. The parts of the two ends of the U-shaped structure extending outward are set as extension plates 81. The extension plates 81 are fixedly connected to the top surface of the support beam 9 by bolts. When the support beam 9 drives the extraction trolley 10 to move, the support cover 8 moves synchronously with the support beam 9.
[0023] A guide wheel 6 is rotatably connected inside the support cover 8. A shaft 7 is penetrated through the guide wheel 6. The shaft 7 is rotatably connected to the guide wheel 6 through a bearing. Both ends of the shaft 7 are fixed to the opposite side walls of the support cover 8 by screws.
[0024] An auxiliary support beam guide rail 2 is axially arranged in the middle of the top surface of the auxiliary support beam 1. The guide wheel 6 is set as a concave wheel. The concave part of the guide wheel 6 straddles on the auxiliary support beam guide rail 2 to guide the rolling direction of the guide wheel 6. When the support cover 8 moves with the support beam 9, the guide wheel 6 rolls along the auxiliary support beam guide rail 2. At the same time, when the extraction trolley 10 lifts the multiple-length round steel, the pressure received by the extraction trolley 10 is transmitted to the support beam 9. The pressure received by the support beam 9 is transmitted to the guide wheel 6 through the support cover 8, and then transmitted from the guide wheel 6 to the auxiliary support beam 1 to share the pressure received by the support beam 9.
[0025] Support columns 4 are arranged at both ends of the bottom surface of the auxiliary support beam 1. The support columns 4 are used to support the auxiliary support beam 1.
[0026] A support gasket 3 is welded on the top surface of the support column 4. The support gasket 3 is fixedly connected to the bottom surface of the auxiliary support beam 1 by a connecting bolt 5. The support gasket 3 is used to increase the connection strength between the support column 4 and the auxiliary support beam 1 and the stability of the support.
[0027] The working principle of the present utility model is described below:
[0028] The multiple-length round steel is transferred from the cooling bed to the roller table in front of the shear. Ten extraction trolleys are required to lift and transfer the multiple-length round steel. The ten extraction trolleys are bolted to the support beam 9 parallel to the axial direction of the multiple-length round steel under the cooling bed, and one extraction trolley is arranged every 1.5 meters; one end of the support beam 9 is connected to the motor through a chain (not shown in the figure), and the motor drives the support beam 9 to move reciprocally; when the multiple-length round steel needs to be transferred, the bracket 101 of the extraction trolley 10 is pushed upward by a hydraulic cylinder (not shown in the figure) to lift the multiple-length round steel; preferably, in order to prevent the multiple-length round steel from rolling off the bracket 101, stop walls are provided upward at both ends of the bracket 101; after the multiple-length round steel is transferred to the roller table in front of the shear, the hydraulic cylinder drives the bracket 101 to descend so that the multiple-length round steel enters the front roller table; during the transfer of the multiple-length round steel, the support beam 9 is subjected to a relatively large pressure from the multiple-length round steel. Through the provided auxiliary support device, the pressure on the support beam 9 is transferred to the auxiliary support beam 1, effectively relieving the pressure on the support beam 9 and improving its service life.
[0029] The chain, motor connection, and hydraulic cylinder mentioned in the present utility model all belong to the prior art and will not be elaborated here.
[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
