Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary tools for protecting gantry crane trolley wires, and particularly relates to a device for increasing the moving space of gantry crane trolley wires. Background Art
[0002] A gantry crane is a lifting device widely used in factories, warehouses, docks and other places for handling heavy objects. The trolley wire system is a key part for supplying power to the gantry crane, usually consisting of a series of conductive rails and current collectors to ensure that the gantry crane can continuously obtain power supply during movement.
[0003] The porcelain insulators of gantry crane trolley wires are important supporting points for fixedly connecting the trolley wires. Affected by thermal expansion and contraction in winter, the trolley wires will expand and contract with the change of weather temperature. Since the structure of the porcelain insulators does not have a compensation function, when the temperature is low in winter, the contraction of the trolley wires is likely to cause damage to the porcelain insulators and the loss of the supporting points of the trolley wires. When the gantry crane runs where there is no supporting point for the trolley wires, it is easy to cause a short circuit of the trolley wires, leading to the risk of electric shock to the crane operator and potential safety hazards.
[0004] Therefore, there is an urgent need to design a device for increasing the moving space of gantry crane trolley wires to solve the problems that the porcelain insulators of the trolley wires do not have compensation, are prone to damage to the porcelain insulators and the loss of the supporting points of the trolley wires, resulting in the risk of electric shock to the crane operator and potential safety hazards. Content of the Utility Model
[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a device for increasing the moving space of gantry crane trolley wires.
[0006] The technical solution adopted by the utility model to solve its technical problems is: a device for increasing the moving space of gantry crane trolley wires, including a fixed block and a connecting shaft. A groove is provided at the top of the fixed block, a horizontal chute is provided in the middle of the fixed block, and the chute is arranged below the groove. A baffle is provided below the connecting shaft, and the baffle and the connecting shaft are threadedly connected in the groove and the chute of the fixed block.
[0007] Specifically, the fixed block is arranged between the original trolley wire porcelain insulator and the trolley wire clamp. The fixed block is movably connected to the trolley wire porcelain insulator through the connecting shaft, and the fixed block is fixedly connected to the trolley wire clamp.
[0008] Specifically, the groove is provided at the top of the fixed block, and the shaft rod of the connecting shaft passes through the groove.
[0009] Specifically, the chute is a strip-shaped hole, and the chute is the moving space for the baffle.
[0010] Specifically, the connecting shaft is arranged below the trolley wire porcelain insulator, and a thread is provided at the lower end of the connecting shaft.
[0011] Specifically, the baffle is a rectangular steel plate, with a threaded hole in the center of the baffle. After the baffle and the connecting shaft are threadedly connected, they slide horizontally in the chute of the fixed block.
[0012] The utility model has the following beneficial effects:
[0013] The device for increasing the moving space of the gantry crane trolley wire designed by the utility model: changes the gantry crane trolley wire insulator to a telescopic property, adds flat iron on the trolley wire clamp, and opens strip holes on the flat iron. In the case of thermal expansion and contraction, the trolley wire can move freely, eliminating the possibility of damage to the supporting insulator caused by the contraction of the trolley wire. Avoids short circuits caused by damage to the trolley wire support points, avoids the risk of electric shock to personnel, and eliminates potential safety hazards. Description of the Drawings
