Detailed Description

As shown in fig. 1-2, a movable rotary lamp holder suitable for underground chamber lighting comprises a movable base 9, wherein the movable base 9 is made of cast-in-place concrete blocks, and the size of the movable base is determined according to the size and height of a projection lamp and the field condition. The bottom of the movable base 9 is provided with a movable roller 10, the upper part of the movable base 9 is embedded with a fixed upright post 8, and the fixed upright post 8 is made of a steel pipe with the diameter of 48 multiplied by 3.5 mm. The fixed upright stanchion 8 is internally sleeved with a jacking upright stanchion 5, and the jacking upright stanchion 5 is made of a steel pipe with the diameter of 32 multiplied by 3.5 mm. The lengths of the fixed vertical rod 8 and the jacking vertical rod 5 can be combined with actual values. Holes are drilled in the jacking upright stanchion 5 and the fixed upright stanchion 8 at intervals of 30cm, and then the holes are fixed through the bolts 3 to adjust the height of the upright stanchions. Safety is required to be paid attention to in the height adjusting process of the vertical rod, safety measures are taken, the jacking vertical rod 5 is inserted into the fixed vertical rod 8 and is not smaller than 50cm, and the number of the inserting pins 3 is not smaller than two.

And the top end of the jacking upright rod 5 is rotatably connected with the lamp holder through a rotary joint 4 and a bolt 3. The adapter 4 is made of a steel pipe with the diameter of 27 multiplied by 3.5mm, the steel pipe is respectively welded and fixed at one end of the lamp bracket opposite to the jacking upright rod 5, and the rotary joint 4 of the lamp bracket and the jacking upright rod are connected by inserting the bolt 3.

The lighting fixture includes that length is multiplied by the width and is 1 mx 0.3 m's frame construction, frame construction is by crossbeam 1, erect roof beam 2 welding and forms, crossbeam 1, erect roof beam 2 and all adopt phi 32 x 3.5mm steel pipe processing to form, frame construction can be according to actual need and light size adjustment, at lighting fixture intermediate position according to the solid fixed ring 7 of profection lamp of size welding, the solid fixed ring 7 of profection lamp adopts phi 14 screw reinforcing bar combination welding to form, it has the screw hole to bore around the solid fixed ring 7 of profection lamp, bolt 14 can push up tightly on the transmission lamp after the screw in.
