Drag chain structure of movable workbench

Abstract

The invention provides a drag chain structure of a movable workbench. The drag chain structure comprises a drag chain body, a drag chain fixing plate, a jacking device, a supporting base and a supporting frame. The drag chain body is flatly laid on the supporting frame. The supporting frame is installed on the supporting base. The supporting frame is provided with a containing cavity. The jackingdevice comprises an upper jacking plate and a lower jacking plate. The lower jacking plate is in threaded connection with the upper jacking plate. The lower jacking plate extends into the containing cavity. One end of the drag chain body is fixed to one side of the supporting frame through the drag chain fixing plate, and the other end passes through the jacking device and is fixed on the other side of the supporting frame through the drag chain fixing plate. The drag chain flattening device is simple in overall structure and ingenious and reasonable in design, flattening operation can be effectively conducted on the drag chain body, and passing of other machines and equipment in a site is not affected while power supply operation is achieved.

Description

technical field [0001] The invention relates to the technical field of drag chains, in particular to a drag chain structure of a mobile workbench. Background technique [0002] With the upgrading of the customer's factory layout, more and more users prefer to adopt the mobile workbench structure, and the control of the mobile workbench needs to lay out the cable structure. At present, there are two conventional methods: tensile cables and drag chains, and tensile cables The installation structure is simple, but the tensile cable is generally a customized model, the cost is high, and the cable is easily damaged due to the direct force of the cable, and the service life is long. Lift the cover plates one by one, and close the slot on the bottom surface by closing the cover plate by its own weight. However, because the cover plate is closed by its own weight, the thickness of the cover plate and the structure of the plow share are relatively large, which wastes materials and is...

[0002] With the upgrading of the customer's factory layout, more and more users prefer to adopt the mobile workbench structure, and the control of the mobile workbench needs to lay out the cable structure. At present, there are two conventional methods: tensile cables and drag chains, and tensile cables The installation structure is simple, but the tensile cable is generally a custom-made model, the cost is high, and the cable is easily damaged due to the direct force of the cable, and the service life is long. Lift the cover plates one by one, and close the slot on the bottom surface by closing the cover plate by its own weight. However, because the cover plate is closed by its own weight, the thickness of the cover plate and the structure of the plow share are relatively large, which wastes materials and is cumbersome to install. The plate shaft is rusted and cannot be closed, which will cause certain damage to the mobile workbench, and will also affect the passage of other mechanical equipment in the site.
