Description

Technical Field

[0001] The utility model belongs to the technical field of stone processing machinery, in particular to a loading and unloading base of a bridge type cutting machine. Background Art

[0002] Slate is made of natural stone and inorganic clay through a special process, and its hardness is relatively high. Therefore, it is usually necessary to use a large cutting machine to cut it. When cutting slate, it is necessary to use a large equipment such as a crane or hoist to lift the slate and place it on the base of the bridge cutting machine. In order to achieve multi-angle cutting of the slate on the base, the bridge cutting machine is usually equipped with a bridge bracket. The bridge bracket is connected to a mounting beam that slides longitudinally, and the cutting head is slidably connected to the mounting beam.

[0003] For example, the existing Chinese patent application [Authorization Announcement No.: CN218557587U] discloses an infrared bridge cutting machine for stone production, including a bracket and a cutting head, and also a base. The top of the base is provided with a mounting hole, and a driving motor is fixed in the mounting hole. The output shaft end of the driving motor is rotatably mounted with a workbench, and the bottom of the workbench is fixed with a No. 1 push rod motor and a No. 2 push rod motor. The output shaft ends of the No. 1 push rod motor and the No. 2 push rod motor are both fixed with a sleeve, and the end of the sleeve close to the base is rotatably connected to a ball, and the ball fits with the surface of the base.

[0004] In the above structure, the stone on the workbench is tilted by tilting the workbench, so that an angled bevel can be cut. However, when loading and unloading the stone, the horizontally placed stone can only be placed on the workbench by a crane or a hoist. However, in order to facilitate movement, the stone is vertically tied to the crane or the hoist for movement. After the processing is completed, the stone also needs to be tied with a binding belt. At this time, the stone is also lifted vertically, and the inclination angle of the workbench is limited, and the stone cannot be erected, which affects the efficiency of stone loading and unloading. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems in the existing technology and propose a loading and unloading base for a bridge type cutting machine. The technical problem to be solved by this utility model is: how to solve the problem of low loading and unloading efficiency of the existing loading and unloading base.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A loading and unloading base of a bridge-type cutting machine includes a cutting head and a base located below the cutting head, a workbench for placing a workpiece on the base is provided, and the workbench can be placed horizontally on the base, and is characterized in that the front side of the workbench is hinged to the front side of the base through a hinge, and a driving member is connected to the base, and the driving shaft of the driving member is hinged to the rear side of the workbench and can drive the workbench to swing along the hinge, and a limit plate is hinged on the side wall on the front side of the workbench, and the limit plate can be located at the front side of the workbench and arranged parallel to the side wall on the front side of the workbench. When the limit plate is rotated to a vertical state, the end of one end of the limit plate protrudes from the upper end surface of the workbench.

[0008] Working principle: When loading, the driving part can be started, and the driving part pushes the back side of the workbench upward. The front side of the workbench and the front side of the base are hinged, so that the workbench stands up, and the limit plate is rotated to a vertical setting. The end of one end of the limit plate protrudes from the upper end surface of the workbench. The workpiece is lifted by a crane or a hoist and placed vertically on the workbench. The lower end of the workpiece is limited by the limit plate to prevent it from sliding out of the workbench. After the workpiece is placed, the driving part can be started, and the driving part pulls the back side of the workbench downward. The back side of the workbench swings down until the workbench is placed horizontally on the base, and then the workpiece is processed by the cutting head. When the workpiece is processed, the limit plate can be rotated to a horizontal position. The limit plate is the entire thing that does not protrude from the upper side of the workbench. The end face, therefore, will not affect the cutting head's processing of the workpiece. When unloading, the limit plate can be rotated to a vertical position again, and then the workbench can be pushed upward by the driving member to set the workpiece vertically. The bottom of the workpiece is limited by the limit plate, which is convenient for a crane or a hoist to lift the workpiece. In addition, during the processing, the workpiece can also be tilted by starting the driving member to facilitate the processing of the workpiece. Through the cooperation of the driving member and the limit plate, rapid loading and unloading of the workpiece is achieved, and the limit plate is rotatable. After achieving the limit on the workpiece, it can be rotated to a horizontal position without affecting the processing of the workpiece. The loading and unloading base not only realizes rapid loading and unloading of the workpiece, but also can prevent it from affecting the cutting processing of the workpiece by rotating the limit plate.

[0009] In the loading and unloading base of the above-mentioned bridge-type cutting machine, an L-shaped limit sleeve is fixedly connected to the workbench, and the limit sleeve has a horizontally arranged hinge plate and a longitudinally arranged blocking plate fixed to the workbench. One end of the limit plate is hinged to the hinge plate, and the other end of the limit plate can be rotated along the hinge point until the side of the limit plate is abutted against the blocking plate when the limit plate is vertically arranged.

[0010] By setting up the L-shaped limit sleeve, the hinged plate can give way to one side of the limit plate when the limit plate rotates, making the rotation of the limit plate smoother. By setting up the blocking plate, the limit of the limit plate when it is set vertically can be directly achieved, thereby making the adjustment of the limit plate more convenient and easy to operate, thereby improving the efficiency of loading and unloading workpieces.

[0011] In the loading and unloading base of the bridge-type cutting machine, the lower end of the hinged plate is raised to form a blocking portion, and when the limit plate is rotated to a horizontal position, the side of the limit plate abuts against the blocking portion.

[0012] The setting of the blocking part enables the limiting plate to be limited by the blocking part when placed horizontally, preventing the limiting plate from sliding horizontally downward, and facilitating the retraction and extension of the limiting plate.

[0013] In the loading and unloading base of the bridge-type cutting machine, two limiting sleeves are provided, and the two limiting sleeves are respectively located at the left and right ends of the front side of the workbench.

[0014] There are two limit sleeves, so that when the workpiece is loaded and unloaded, the two limit plates can respectively limit the left and right ends of the working side, thereby improving the stability of the workpiece limit.

[0015] In the loading and unloading base of the above-mentioned bridge-type cutting machine, the workbench includes a chassis, the middle part of the chassis is vertically arranged and rotatably connected to a central axis, a gear disc is sleeved on the central axis, and a support disc for placing a workpiece is connected above the gear disc. A driving motor is fixedly connected to the chassis, and a main gear meshing with the gear disc is connected to the output shaft of the driving motor. The driving motor drives the main gear to rotate, thereby driving the gear disc and the support disc to rotate.

[0016] A driving motor is fixedly connected to the chassis, a main gear is connected to the output shaft of the driving motor, and a gear disc is sleeved on the central axis of the chassis. By starting the driving motor, the main gear of the driving motor can drive the gear disc to rotate. Since the support disc is fixedly connected to the gear disc, the rotation of the gear disc drives the rotation of the support disc, thereby realizing 360-degree rotation of the workbench in the horizontal direction, and combined with the setting of the driving part, the workbench can be rotated and tilted in multiple directions, which is convenient for processing the workpiece and improves the convenience of processing.

[0017] In the loading and unloading base of the above-mentioned bridge-type cutting machine, a plurality of supporting flat wheels are arranged on the chassis, and the plurality of supporting flat wheels are evenly distributed along the circumference of the chassis. A circular support plate is arranged on the support plate, and the axis of the support plate coincides with the axis of the central axis, and the upper end of the supporting flat wheel is against the support plate.

[0018] Since the workpiece is generally a stone slab, etc., it is heavy, and the rotation of the support plate is unstable if it only relies on the rotation of the toothed plate and the gear. This application realizes circumferential support for the rotation of the support plate by providing a supporting flat wheel and a supporting plate, making the rotation of the support plate more stable.

[0019] In the loading and unloading base of the above-mentioned bridge-type cutting machine, a positioning block is provided under the support plate, a positioning cylinder is provided on the chassis, a V-shaped positioning groove is provided on the positioning block, and the notch of the positioning groove is arranged laterally outward. The piston rod of the positioning cylinder has an inverted V-shaped positioning part, and the positioning part can be embedded in the positioning groove to limit the circumferential position of the positioning block.

[0020] By setting the positioning block, the support plate can be positioned when processing the workpiece, so that the support plate can be placed stably. After rotation, it can also be quickly reset by setting the positioning block, which improves the convenience of using the support plate.

[0021] In the loading and unloading base of the bridge-type cutting machine mentioned above, a plurality of positioning blocks are provided, and the plurality of positioning blocks are evenly distributed along the circumference of the support plate, and the positioning blocks are all located on the inner side of the support plate.

[0022] The arrangement of this structure enables the support disc to only need the positioning portion to position one of the positioning blocks when rotating. The arrangement of multiple positioning blocks can achieve multi-angle positioning of the support disc, thereby improving the convenience of positioning.

[0023] In the loading and unloading base of the above-mentioned bridge-type cutting machine, the driving member is a turning cylinder, and the end of the piston rod of the turning cylinder is hinged to the rear end of the chassis.

[0024] The setting of the hinged position of the piston rod of the turning cylinder enables the turning cylinder to stably drive the rear end of the entire workbench to swing up and down, thereby improving the stability of loading and unloading workpieces.

[0025] Compared with the existing technology, the loading and unloading base of the bridge cutting machine of the utility model has the following advantages: through the cooperation of the driving part and the limit plate, the workpiece can be quickly loaded and unloaded, and the limit plate is rotatable. After the workpiece is limited, it can be rotated to be placed horizontally without affecting the processing of the workpiece. The loading and unloading base not only realizes the rapid loading and unloading of the workpiece, but also can prevent the workpiece from being cut by rotating the limit plate.
