[0023] A safety protection device for the construction of a bridge pier pad stone comprises a second L-shaped steel plate 12, a steel cable 2 is fixedly connected to one side of the second L-shaped steel plate 12, three groups of first L-shaped steel plates 1 are passed through the outer side of the steel cable 2, and the opposite sides of the first L-shaped steel plate 1 and the second L-shaped steel plate 12 are fixedly connected to support plates 13, and when the support plates 13 are placed on the top of the bridge pier column, the support plates 13 can play a supporting role for the first L-shaped steel plate 1. The insides of the two groups of first L-shaped steel plates 1 are both provided with L-shaped through holes 3 that match the first L-shaped steel plates 1, and one side of the second L-shaped steel plate 12 is provided with a through hole 5, and the first L-shaped steel plate 1 passes through the through hole 5, and the steel cable 2 can connect and tighten each group of the first L-shaped steel plate 1 and the second L-shaped steel plate 12, so that each group of the first L-shaped steel plate 1 and the second L-shaped steel plate 12 can be fixed to the four corners of the bridge pier column respectively.

[0024] A guide pulley 16 is rotatably connected between the two sets of fixed plates 4. The steel cable 2 passes over the outer side of the guide pulley 16. The guide pulley 16 can guide the steel cable 2, thereby reducing the wear between the steel cable 2 and the second L-shaped steel plate 12. The bottom of each set of support plates 13 is movably connected with a ball 14. The bottom of each set of ball 14 is located at the same horizontal height. The ball 14 can reduce the friction between the support plate 13 and the top of the pier column when the steel cable 2 is tightened to drive the first L-shaped steel plate 1 and the support plate 13 to move, thereby reducing the probability of the support plate 13 causing wear to the pier column when moving. The end of the first L-shaped steel plate 1 away from the second L-shaped steel plate 12 is fixedly connected to a reel 6. The outer side of the reel 6 is symmetrically rotatably connected to the fixed plate 4. The two sets of fixed plates 4 are fixedly connected to the second L-shaped steel plate 12. The reel 6 can reel the steel cable 2 when rotating.

[0025] A limiting mechanism 7 is provided on one side of the reel 6. The limiting mechanism 7 includes a worm wheel 72 fixedly connected to one end of the reel 6. A worm 71 is meshedly connected to the outer side of the worm wheel 72. A connecting block 73 is symmetrically rotatably connected to the outer side of the worm 71. Both sets of connecting blocks 73 are fixedly connected to the second L-shaped steel plate 12. When the worm 71 rotates, it can drive the worm wheel 72 and the reel 6 to rotate, thereby realizing the rotation adjustment of the reel 6. At the same time, the self-locking property of the transmission of the worm 71 and the worm wheel 72 can limit the probability of the reel 6 rotating on its own. A first slot 10 is provided on one side of the second L-shaped steel plate 12 and each group of the first L-shaped steel plates 1. A matching fixed baffle plate 8 is inserted into the interior of each group of the first slot 10. The first slot 10 is used for inserting the fixed baffle plate 8, thereby limiting the position of the first slot 10.

[0026] The side of each group of fixed enclosure plates 8 away from the first slot 10 is slidably connected with a dynamic enclosure plate 9, and the other side of each group of first L-shaped steel plates 1 and second L-shaped steel plates 12 is provided with a second slot 15 adapted to the dynamic enclosure plate 9. Each group of dynamic enclosure plates 9 is respectively inserted into the interior of the second slot 15 shown in each group. When the dynamic enclosure plate 9 is inserted into the interior of the second slot 15, it can enclose the area between the two adjacent groups of first L-shaped steel plates 1 or the second L-shaped steel plates 12 and the first L-shaped steel plate 1 with the fixed enclosure plate 8, so as to reduce the probability of construction workers falling from the pier columns during the construction of the bridge pier pad stone. The top of each group of fixed enclosure plates 8 is threadedly connected with a limiting bolt 11, and each group of limiting bolts 11 abuts against the top of each group of dynamic enclosure plates 9. When the limiting bolts 11 are tightened against the dynamic enclosure plate 9 when they are screwed, they can play a role in limiting the dynamic enclosure plate 9, thereby reducing the probability of the dynamic enclosure plate 9 escaping from the second slot 15.

[0027] When in use, the corresponding groups of support plates 13 on the three groups of first L-shaped steel plates 1 and second L-shaped steel plates 12 are respectively placed at the top four corners of the bridge pier column, and then the worm 71 is rotated, so that the worm 71 can drive the worm wheel 72 and the reel 6 to rotate when it rotates, and the reel 6 can reel up the steel cable 2 when it rotates, so that the steel cable 2 can gradually tighten and fix each group of L-shaped through holes 3 and the steel cable 2 to the bridge pier column, thereby realizing the installation and fixation of each group of first L-shaped steel plates 1 and second L-shaped steel plates 12, and then take out each group of fixed enclosure plates 8 and insert them into the interior of each group of first slots 10, and then slide the movable enclosure plates 9 into the corresponding second slots 15 until each group of movable enclosure plates 9 is inserted into the interior of each group of second slots 15, and then rotate each group of limiting bolts 11 until each group of limiting bolts 11 is screwed to each group of movable enclosure plates 9, thereby realizing the limiting fixation of each group of movable enclosure plates 9, thereby realizing the installation of the entire protective device.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
