The purpose of this utility model is achieved as follows: a knife gate maintenance frame, including a lifting mechanism made of pulleys, hooks and ropes, is characterized in that the base is provided with a bracket, the upper part of the bracket is distributed with a pulley of the lifting mechanism, the base The bottom is provided with a groove inward, and the two sides of the groove are respectively provided with locking rods which can be inserted into the groove.

The upright rod of the bracket is arranged in the support tube on the base, and the upright rod can rotate 360 degrees.

The utility model is used in the maintenance of the knife switch, which can save time and labor, improve work efficiency, and prevent potential safety hazards caused by personnel working with heavy loads at high altitudes. The utility model has a simple structure and is convenient and flexible to use.

Description of drawings

Fig. 1 is the structural representation of the tractor of the present utility model;

Fig. 2 is a bottom view of the base of Fig. 1 .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figures 1 and 2, the cross-shaped support is composed of a vertical rod 1 and a beam 2. The vertical rod is inserted into the support tube 4 on the base 3, and the vertical rod can rotate 360 degrees. Movable pulleys 5 are arranged on the beam, fixed pulleys 6 are arranged at both ends, and fixed pulleys 7 are arranged on the top of the pole, and hooks 9 are connected by ropes 8 wound on the pulley block, thereby constituting a lifting mechanism. The bottom of the base is inwardly provided with a through groove 10, and movable locking rods 11 are respectively arranged on both sides of the groove, and the locking rod can extend into the groove by moving inward. The cross section of the lock bar is oblate, and the lock bar is provided with a handle 12 for easy operation. The upper part of the bracket is provided with reinforcing ribs 13 connecting the beam and the vertical bar.

When used for lifting equipment, first fix the base of the knife gate maintenance frame on the channel steel 14 at the bottom of the knife gate, that is, the groove of the base is seated on the channel steel, the channel steel falls into the groove, and is inserted from both sides to the In the groove, and rotate the lock lever to make it close to the channel steel to complete the fixation, and then insert the bracket pole on the base support tube, and realize the up and down transmission of the equipment through manual control of the lifting mechanism. If you need to change the angle, you can do it by rotating the pole.

Claims (2)
