When the lifting pipe is manually rotated, since the upper lifting internal thread and the lower lifting internal thread are in opposite directions, the rotation of the lifting pipe drives the lower fixed frame to move upwards, thereby playing the role of lifting the catenary trolley. The catenary trolley is lifted by the threaded lifting pipe, which can be operated by only one operator, saving manpower and material resources, and avoiding potential safety hazards in manual lifting.

Preferably, the lower fixing frame includes a fixing hook and a connecting rod, one end of the connecting rod is screwed to the lifting pipe, and the other end of the connecting rod is hinged to the fixing hook. The lower fixing frame includes a fixing hook and a connecting rod. The fixing hook is used to fix the suspension beam trolley. The connecting rod is used to connect the fixing hook and the lifting pipe. One end of the connecting rod is threaded with the lifting pipe, and the other end of the connecting rod is hinged with the fixing hook. When the suspension beam trolley is hoisted, both the fixed hook and the connecting rod bear the pulling force. When the direction of the pulling force is different, the hinge joint of the connecting rod and the fixing hook can change the direction to adapt to the vertical lifting of the catenary trolley.

Preferably, the fixed hook is L-shaped, one end of the fixed hook is hinged to the connecting rod, and the other end of the fixed hook is bent upward to form a hook shape. The fixed hook is L-shaped. One end of the L-shaped fixed hook is hinged with the connecting rod, and the other end is bent upwards to form a hook. The hook-shaped end can be used to hook the catenary trolley, and the gravity of the catenary trolley is vertically downward. , the upwardly bent hook-shaped end can withstand the gravity of the catenary trolley and carry out lifting.

Preferably, the connecting chain is a flexible structure. The connecting chain is a flexible structure, and the gravity of the catenary trolley is applied to the connecting hook, and the connecting hook can adjust the positions of the connecting hook and the connecting chain according to the position of the center of gravity.

Therefore, the catenary trolley maintenance auxiliary tool of the present utility model has the following advantages: 1. When the lifting pipe is manually rotated, since the upper lifting internal thread and the lower lifting internal thread are opposite in direction of rotation, the rotation of the lifting pipe drives the lower fixing frame upward. Move, and then play the role of lifting the catenary trolley, using the threaded lifting pipe to lift the catenary trolley, only one operator is needed to operate, saving manpower and material resources, and avoiding potential safety hazards when manpower is lifted; 2. Fixed The frame includes a fixed hook and a connecting rod. The fixed hook is used to fix the suspension beam trolley. The connecting rod is used to connect the fixed hook and the lifting pipe. One end of the connecting rod is threaded with the lifting pipe, and the other end of the connecting rod is hinged with the fixing hook. When the trolley is suspended, both the fixed hook and the connecting rod bear the tensile force. When the direction of the pulling force is different, the hinge of the connecting rod and the fixed hook can change the direction, which is suitable for the vertical lifting of the catenary trolley; 3. The connecting chain is a flexible structure. Gravity is exerted on the connecting hook, and the connecting hook can adjust the position of the connecting hook and the connecting chain according to the position of the center of gravity.
