Description

Technical Field

[0001] The utility model belongs to the technical field related to trolley power connection, and particularly relates to a centrally movable left-right vertical plug-in device. Background Art

[0002] The electric heating trolley furnace is an industrial heating equipment, which is mainly used for heating metal materials, such as annealing, normalizing, quenching, tempering, etc. The characteristics of this type of furnace are that heat is generated by electric heating elements, the movement of the trolley is used to load and remove the workpiece, and the uniformity and repeatability of the heating process are ensured by a precise temperature control system. The electric heating trolley furnace has been widely used in the metal heat treatment industry due to its high efficiency, energy saving, easy control and maintenance. When the trolley is running, in order to ensure the operation of the trolley, the trolley needs to be connected to the power supply through the socket device, but it still has the following disadvantages in actual use:

[0003] 1. During the operation of the trolley, the power connection structure needs to be installed on the trolley to supply power to the trolley. When the trolley heats the internal workpiece, the trolley generates heat, expands itself, and changes in size. The plug-in structures are plugged in and tightened together, which will cause the plug-in structure to be squeezed and bent, causing the plug-in structure to deform, affecting the use of the plug-in structure;

[0004] 2. During the operation of the trolley, the socket strip structures are directly connected to each other through plugging. During long-term use, it is easy to cause the plug-in structures to loosen, resulting in poor contact of the socket strip structures and affecting the power connection effect. Utility Model Content

During operation, the L-shaped mounting plate is installed through the fixing block on the external mounting channel steel, and is connected to an external power connection structure through the L-shaped mounting plate. The L-shaped mounting plate is clamped on the accommodating frame through the clamping plate on the accommodating frame for good power connection, and the movement of the external mounting channel steel and the fixed channel steel in the vertical direction and the length direction of the fixed channel steel is limited by the limiting assembly.

[0008] Furthermore, two mounting frames are fixed to the side of the outer mounting channel away from the fixing seat, two mounting studs are fixed to the side of each fixing seat away from the outer mounting channel along the vertical center line, and the outer mounting channel is installed at the installation position on the trolley through the mounting frame.

The accommodating frame is inserted into the fixed channel steel through the plug-in stud, and with the cooperation of the mounting nut, the accommodating frame is installed on the fixed channel steel.

[0011] Furthermore, the limiting assembly includes a fixed block and an insertion rod. The fixed block is fixed in the middle of the bottom of the external mounting channel steel, and the insertion rod is fixed on the side of the fixed block close to the fixed channel steel.

[0015] 2. The utility model solves the problem that the strip structure is prone to loosening and causing poor contact after long-term use during the operation of the trolley by providing an L-shaped mounting plate and a accommodating frame. When the position between the outer mounting channel steel and the fixed channel steel changes, the position of the insertion rod between the fixed sleeve and the fixed block 2 changes. The movable connection between the insertion rod, the fixed block 2 and the fixed sleeve limits the position change of the outer mounting channel steel and the fixed channel steel in the vertical direction, and at the same time, cooperates with the L-shaped mounting plate and the clamping plate to limit the position change of the outer mounting channel steel in the length direction. At the same time, the clamping force is provided by the rebound of the spring leaf, so that the two clamping plates remain clamped and fastened with the long part of the L-shaped mounting plate, preventing the L-shaped mounting plate and the clamping plate from loosening and causing poor contact when connecting to the power supply, and better preventing the strip structure from loosening after long-term use during the operation of the trolley, thereby ensuring the power connection effect of the strip structure during the operation of the trolley.
