Description
Technical Field
[0001] This utility model relates to the field of track conveying equipment technology, and in particular to the machine foot device for connecting the gantry and the track. Background Technology
[0002] In daily tile production, the polishing process is typically the end of the tile production line. After polishing, the tiles usually need to be stacked and transported to an automated tile packaging line for automated packaging. Existing stacking equipment uses two tile clamping devices and a tile transfer cart for transport and stacking. The clamping devices have their feet fixed to the ground, and the transfer cart moves back and forth, resulting in low efficiency and high cost. Alternatively, the clamping device's frame can have its feet slidably fixed to a track via bearing wheels, allowing it to move back and forth for handling and stacking. However, during this movement, the frame is prone to swaying, resulting in poor stability and affecting the efficiency of handling and stacking. Summary of the Invention
[0003] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a machine foot device for connecting the frame and the track.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The machine foot device connecting the gantry and the rail includes a support foot slidably disposed on the upper surface of the middle rail and two sets of clamping modules; each end of the support foot is provided with a set of clamping modules; each clamping module includes at least two fixed seats, at least two fixed wheels, two bearing wheels, and a dustproof unit; each side of the support foot along the length direction of the middle rail is provided with a fixed seat and a fixed wheel, and each fixed seat is fixedly connected to a fixed wheel; the upper end of the fixed seat is fixedly connected to the lower surface of the support foot, and the fixed wheel is located in a groove on the side of the middle rail; the fixed wheel is inclined so that the upper surface of the fixed wheel abuts against the upper side wall of the groove; the bearing wheel is bearing connected to the lower surface of the support foot, and the circumferential side of the bearing wheel is rotatably connected to the side of the middle rail; the dustproof unit is disposed on the end face of the support foot to protect the fixed wheel and the bearing wheel.
[0006] By adopting the above technical solution, a steel support frame is installed on the upper surface of the support legs. The lower part of the support legs is stably fixed to the central rail by two sets of clamping modules, ensuring stable operation of the steel support frame. Multiple fixed wheels engage with grooves in the central rail, limiting the vertical movement of the steel support frame and preventing it from tipping over, thus ensuring high safety. Bearing wheels not only limit the horizontal movement of the steel support frame, preventing lateral swaying, but also reduce friction and improve operating efficiency. The combination of fixed wheels and bearing wheels ensures the stability of the steel support frame during handling and improves stacking efficiency, while also reducing costs. Furthermore, the dustproof unit ensures the cleanliness of the fixed wheels and bearing wheels, reducing the failure rate and making it more convenient to use.
[0007] Furthermore, the fixing base includes a first fixing plate, a second fixing plate, and a bearing connecting rod. The first fixing plate is fixedly connected to the lower surface of the support foot, the upper end of the second fixing plate is fixedly connected to the first fixing plate, and the lower end of the second fixing plate is bent away from the center rail, resulting in a more compact structure. A fixing hole is provided at the lower end of the second fixing plate, through which one end of the bearing connecting rod passes, and the other end of the bearing connecting rod is located within the groove and connected to the fixing wheel, making installation and disassembly more convenient.
[0008] Furthermore, the supporting foot includes a support box, a first drive module, and a second drive module. One end of the support box is bolted to the first drive module, and the other end of the support box is bolted to the second drive module. A first fixing plate is bolted to the lower surface of the connection points between the support box and the first drive module, and between the support box and the second drive module. One side of the first fixing plate is bolted to the support box, and the other side of the first fixing plate is bolted to the corresponding first drive module or second drive module, thereby improving the stability of the structure and the overall load-bearing capacity.
[0009] Furthermore, the dustproof unit includes a dust cover, the upper end of which is fixedly connected to the end of the supporting foot. The lower end of the dust cover is provided with a downward-opening clearance groove, through which the middle rail passes. Protective parts are provided on both sides of the clearance groove, covering the sides of the corresponding bearing wheels, which helps to protect the bearing wheels and the fixed wheels, improves working efficiency, and reduces maintenance costs.
[0010] Furthermore, the dustproof unit also includes a cleaning brush, which comprises a mounting part and a brush. The mounting part is fixed to the dustproof cover, and the brush is mounted on the mounting part. The lower surface of the brush abuts against the middle rail, which can effectively remove dust and other impurities on the middle rail, prevent impurities from entering the bearing, and improve the stability and smoothness of operation.
[0011] Furthermore, a mounting cover is provided at the upper end of the dust cover in the recessed groove, and the two sides of the mounting cover have different thicknesses along the length of the middle rail. The mounting part is screwed to the side of the mounting cover away from the dust cover, and the length direction of the cleaning brush is arranged intersecting the length direction of the dust cover, which facilitates timely cleaning of impurities on the middle rail to outside the operating area, prevents dust from accumulating on the track, and improves the quality and efficiency of cleaning.
[0012] In summary, the beneficial effects of this utility model are as follows:
[0013] The upper surface of the support legs of this utility model is equipped with a steel support frame. The lower part of the support legs is stably fixed to the central rail by two sets of clamping modules, ensuring stable operation of the steel support frame. Multiple fixed wheels engage with grooves in the central rail, limiting the vertical movement of the steel support frame and preventing it from tipping over, thus ensuring high safety. Bearing wheels not only limit the horizontal movement of the steel support frame, preventing lateral swaying, but also reduce friction and improve operating efficiency. The combination of fixed wheels and bearing wheels ensures the stability of the steel support frame during handling and improves stacking efficiency, while also reducing costs. Furthermore, a dustproof unit ensures the cleanliness of the fixed wheels and bearing wheels, reducing the failure rate and making it more convenient to use. Attached Figure Description
