Existing bridge construction drilling platforms generally require protection during construction to prevent construction equipment or personnel from falling into the water and causing safety accidents. Therefore, we provide a bridge construction drilling platform with protective effects. Utility Model Content

Through the protective mechanism, it solves the problem that existing bridge construction drilling platforms generally need to be protected during construction to prevent construction tools or personnel from falling into the water and causing safety accidents.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a bridge construction drilling platform with protective effect, including a base plate, a protective mechanism on the top of the base plate, and an extension mechanism on the top of the base plate.

[0007] The protective mechanism includes a fixed column, a placement plate fixedly connected to the top of the fixed column, a fixed frame one fixedly connected to the top of the placement plate, and several fixed frames one. A connecting rod is rotatably connected to the inner wall of the fixed frame one, and a fixed frame two is rotatably connected to the outer wall of the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a protective mechanism, lifts the handrail. When the handrail is lifted, it will drive the second fixed frame to move simultaneously. At this time, the connecting rod located on the inner wall of the second fixed frame will move upward at the same time. When the connecting rod moves to the appropriate position, the grip block is pinched and moved upward at the same time. At this time, the spring will also be compressed at the same time, and the locking block located at the bottom of the grip block will also be lifted. If the handrail is moved further, the locking block will be locked into the fixed frame. Its advantage is that it facilitates protection and protects the workers who are working on it, greatly increasing the safety during construction.

[0017] 2. This utility model, by setting up an extension mechanism, starts a motor to drive the transmission shaft to rotate. When the transmission shaft rotates, it will drive the pulley one fixedly connected to its outer wall to rotate simultaneously. At this time, the belt on the outer surface of the pulley one will drive the pulley two to rotate simultaneously. When the pulley two rotates, the rotating rod on its outer wall will also rotate simultaneously. At this time, the gear on the outer surface of the rotating rod will also rotate. Because the main rod meshes with the gear, the main rod will move when the gear rotates. At this time, the two connecting rods at the end of the main rod will move along the groove of the limiting block after being pushed, thereby driving the extension plate at the top of the connecting rod one to move and extend out simultaneously. Its advantage is to expand the construction space and reduce personnel crowding.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

There are two handrails 106.

[0030] The extension mechanism 2 includes a main rod limiting block 201. The bottom of the main rod limiting block 201 is fixedly connected to the top of the base plate 11. A main rod 202 is slidably connected to the inner wall of the main rod limiting block 201. Two connecting rods 203 are pulled by the main rod 202. Two connecting rods 203 are rotatably connected to the outer surface of the main rod 202. A second connecting rod 204 is rotatably connected to the inner wall of the first connecting rod 203. The extension plate 206 is pulled by the second connecting rod 204. A limiting block 205 is fixedly connected to the top of the base plate 11. The outer surface of the second connecting rod 204 is slidably connected to the inner wall of the limiting block 205. The limiting block 205 restricts the movement of the second connecting rod 204. An extension plate 206 is fixedly connected. A toothed groove 209 is opened inside the main rod 202. A motor placement plate 207 is fixedly connected to the outer wall of the placement plate 102. A motor 208 is placed through the motor placement plate 207. A motor 208 is fixedly connected to the top of the motor placement plate 207. A transmission shaft 214 is fixedly connected to the bottom output end of the motor 208 through a coupling. The motor 208 drives the transmission shaft 214 to rotate. A pulley 215 is fixedly connected to the outer wall of the transmission shaft 214. A belt 216 is connected to the outer surface of the pulley 215.

[0031] A rotating rod 212 is fixedly connected to the outer wall of pulley 217. A rotating frame 210 is fixedly connected to the bottom of motor mounting plate 207, through which the rotating rod 212 rotates. The inner wall of the rotating frame 210 is rotatably connected to the outer surface of the rotating rod 212. A gear 211 is fixedly connected to the outer surface of the rotating rod 212, through which the gear 211 meshes with the main rod 202, thereby driving the main rod 202 to move. The outer surface of the gear 211 is meshed with the main rod 202. The extension plate 206 is topped... The main rod 202 is fixedly connected to a main barrier plate 218 to prevent falls. A secondary barrier plate 219 is rotatably connected to the outer wall of the main barrier plate 218. A threaded block 220 is fixedly connected to the top of the placement plate 102. The secondary barrier plate 219 is fixed by inserting a threaded rod 221 into the main rod 202. The threaded rod 221 is threadedly connected to the inner wall of the threaded block 220. A limit plate 213 is fixedly connected to the top of the base plate 11 to limit the movement of the main rod 202.

[0032] One specific application of this embodiment is:

[0033] When workers are carrying out construction, they need to use a barrier to prevent falls. Lifting the handrail 106 causes the fixing frame 105 to move simultaneously. At the same time, the connecting rod 104 located on the inner wall of the fixing frame 105 moves upwards. Once the connecting rod 104 reaches the appropriate position, the grip block 109 is squeezed and moved upwards. Simultaneously, the spring 108 is compressed, and the locking block 111 at the bottom of the grip block 109 is lifted. Continuing to move the handrail 106 causes the locking block 111 to engage inside the fixing frame 107. This provides protection for workers using the handrail, greatly increasing safety during construction. The handrail can be extended or adjusted when the work area is too small. Starting the motor 208 drives the drive shaft 214 to rotate. When the drive shaft 214 rotates, it drives the leather belt fixedly connected to its outer wall. When pulley 215 rotates simultaneously, belt 216 on the outer surface of pulley 215 drives pulley 217 to rotate simultaneously. When pulley 217 rotates, rotating rod 212 on its outer wall also rotates simultaneously. At the same time, gear 211 on the outer surface of rotating rod 212 also rotates. Since main rod 202 meshes with gear 211, main rod 202 moves when gear 211 rotates. At this time, the two connecting rods 203 at the end of main rod 202 are pushed and move along the groove of limiting block 205, thereby driving extension plate 206 at the top of connecting rod 203 to move and extend out. Then, the secondary barrier plate 219 is turned around, and threaded rod 221 is inserted into threaded block 220 to limit the secondary barrier plate 219. The advantage is that it expands the construction space and reduces personnel crowding.
