Description

Technical Field

[0001] The utility model relates to a protective device, in particular to a safety protective device for the fastening construction of wind turbine anchor bolts, and belongs to the technical field of anchor rod foundation installation. Background Art

[0002] During the installation and construction of wind power foundation anchor bolts, after the anchor bolts are punched into place, it is necessary to adjust the exposed length of the anchor bolts and tighten them with torque. At the same time, the upper anchor plate needs to be leveled. During this process, workers are required to climb to the top of the upper anchor plate to cooperate with the construction. According to existing construction safety measures, after climbing to the upper anchor plate, the double rope safety belt needs to be passed through the lower part of the upper anchor plate and locked, or scaffolding can be set up outside the anchor plate to ensure the safety of the workers. However, these two methods have large limitations on the distance that workers can move, and the safety rope needs to be unhooked and moved step by step, which makes it inconvenient for workers to operate and the investment is too high. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a safety protection device for wind turbine anchor bolt fastening construction, so that workers can hang the safety belt on a ring or a wire rope during construction to avoid potential safety hazards that may occur during the moving process and ensure the safety of construction.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A safety protection device for wind turbine anchor bolt fastening construction comprises a steel pipe, a circular ring is arranged on the top of the steel pipe, a circular hole is dug in the middle and lower part of the outer wall of the steel pipe, a strip-shaped through hole is dug below the circular hole, ear plates are respectively arranged on both sides of the strip-shaped through hole, and a bolt is arranged between the two ear plates.

[0006] The lower end of the strip-shaped through hole passes through the bottom of the steel pipe.

[0007] The inner diameter of the steel pipe matches the outer diameter of the anchor bolt.

[0008] There are six steel pipes evenly distributed on the anchor bolts, and steel wire ropes are arranged between adjacent steel pipes. The steel wire ropes are located on the circular rings on the tops of the steel pipes.

[0009] The exterior of the steel pipe is painted with red and white two-color paint.

[0010] The positive beneficial effects of the utility model are:

[0011] 1. The utility model provides a ring at the top of the steel pipe, which is convenient for the staff to hang the safety belt on the ring. At the same time, a steel wire rope can be hung between the six steel pipes, so that the staff can also hang the safety belt on the steel wire rope. It is flexible to use and easy to operate, avoiding potential safety hazards during the movement process.

[0012] 2. The utility model can eliminate the tightening stress at the lower part by digging a circular hole at the middle and lower part of the steel pipe, and can facilitate fixing the steel pipe and the anchor rod by arranging ear plates on both sides of the strip-shaped through hole and arranging bolts between the ear plates, thereby preventing the steel pipe from falling out of the anchor bolt and ensuring the safety and stability of the construction.

[0013] 3. The utility model is simple to make and easy to install. The workers do not need to carry out scaffolding, which reduces the construction cost, increases the operating range of the workers, improves the work efficiency of the workers in the tightening and leveling of the anchor bolts, and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] Figure 2 This is a diagram showing the use status of the steel wire rope of the utility model;

[0016] Among them: 1-steel pipe, 2-circular ring, 3-circular hole, 4-strip through hole, 5-ear plate, 6-bolt, 7-steel wire rope. DETAILED DESCRIPTION

[0017] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0018] For example, see Figure 1-Figure 2 A safety protection device for wind turbine anchor bolt fastening construction includes a steel pipe. A ring 2 is arranged on the top of the steel pipe 1, a circular hole 3 is dug in the middle and lower part of the outer wall of the steel pipe 1, a strip through hole 4 is dug below the circular hole 3, ear plates 5 are respectively arranged on both sides of the strip through hole 4, and a bolt 6 is arranged between the two ear plates 5.

[0019] The lower end of the strip-shaped through hole 4 passes through the bottom of the steel pipe 1 .

[0020] The inner diameter of the steel pipe 1 matches the outer diameter of the anchor bolt.

[0021] There are six steel pipes 1 evenly distributed on the anchor bolts, and steel wire ropes 7 are arranged between adjacent steel pipes 1 . The steel wire ropes 7 are located on the ring 2 at the top of the steel pipe 1 .

[0022] The outside of the steel pipe 1 is painted with red and white two-color paint.

[0023] In the above description, the width and length of the column steel pipe and the pipe wall opening can be selected and manufactured and used according to the length and specifications of the exposed anchor bolts of the anchor plate on site.

[0024] When in use, one wind turbine foundation is equipped with 6 of these protective columns. The bottom end of the column is inserted into the exposed inner ring anchor of the upper anchor plate and penetrated for about 200mm. It is fastened with fastening bolts to prevent the column from easily falling out of the anchor. Workers can clip the double-rope safety belt buckle into the upper ring of the column (or pass a φ12 plastic-coated steel wire rope through the upper rings of the 6 columns and clip the buckle onto the steel wire rope) to achieve the purpose of safety protection.

[0025] In actual operation, the length of the steel pipe is 1000mm. The circular ring held by the welded steel bar is welded to the top of the steel pipe, serving as a hanging point for the safety rope buckle. A 14mm hole is drilled at the bottom 260mm away from the bottom end to eliminate the lower fastening stress. A 5mm wide pipe wall is cut off vertically from the bottom to the bottom end, and two teams of ear plates are welded on the remaining pipe wall. The ear plates are opened and used with bolts and gaskets for fastening.

[0026] The utility model provides a circular ring at the top of the steel pipe, which is convenient for workers to hang the safety belt on the circular ring. At the same time, a steel wire rope can be hung between the six steel pipes, so that the workers can also hang the safety belt on the steel wire rope. The utility model is flexible to use and simple to operate, avoiding potential safety hazards that may occur during the moving process, and ensuring the safety and stability of the construction.
