Description

Technical Field

[0001] This utility model relates to the field of installation and construction technology, and in particular to a safety protection device for the installation of wind turbine anchor bolts. Background Technology

[0002] The installation of wind turbine anchor bolts is a key engineering step in fixing the wind turbine tower to the foundation. It mainly involves inserting high-strength anchor bolts into pre-drilled holes in the concrete foundation and then connecting and fixing them to the flange at the bottom of the tower. During construction, it is often necessary to use lifting equipment to raise the construction platform to facilitate the operation of the workers.

[0003] Existing technologies often suffer from the following drawbacks: In many current wind power projects, inadequate safety precautions are commonly observed during the installation of anchor bolts on wind turbine foundations. Safety belts are often caught on crane hooks, operations do not comply with relevant safety regulations, and this wastes valuable machinery operating time.

[0004] Therefore, this utility model provides a safety protection device for the installation of wind turbine anchor bolts. Utility Model Content

[0005] This device is designed for reuse and can provide effective safety protection for construction workers during installation. It can protect workers working at heights, freeing up cranes to be used for other operations, thus achieving the goal of reducing mechanical input from a macro perspective.

This device provides safety protection for construction workers during the anchor bolt and anchor plate installation process in the basic installation stage, and is an innovation compared with the traditional method.

[0008] Preferably, two flexible ropes are fixedly connected between the two uprights.

[0009] The effect achieved by the above components is that adjacent uprights are connected by soft ropes to form a safety fence.

[0010] Preferably, the side wall of the upright has an insertion hole, the inner side of the clamp is fixedly connected to a connecting block, and the inside of the connecting block is slidably connected to an insertion rod, the size of the insertion rod being adapted to the size of the insertion hole.

[0011] The effect achieved by the above components is that the insert rod is inserted into the inside of the insertion hole, thereby completing the fixing work between the upright rod and the clamp.

[0012] Preferably, a retaining ring is fixedly connected to the side wall of the insertion rod, and a stop block is fixedly connected to the end side of the insertion rod.

[0013] The effect achieved by the above components is that the stop and the retaining ring prevent the insert rod from slipping out of the connecting block.

[0014] Preferably, the surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the retaining ring and the connecting block, respectively.

[0015] The effect achieved by the above components is that the retaining ring will be driven by the spring force to insert the plug rod into the inside of the socket.

[0016] Preferably, a fixing block is fixedly connected to the surface of the connecting block, and a baffle is slidably connected inside the fixing block.

[0026] Reference Figure 1-3 As shown, this utility model provides a technical solution: a safety protection device for wind turbine anchor bolt installation, comprising several uprights 1.

[0027] The following is a detailed explanation of its overall setup and function.

[0028] In this implementation plan: several uprights 1 are grouped in pairs. A clamp 2, U-shaped in structure, is detachably installed on the lower side of each upright 1. A steel wire rope 3 is fixedly connected to the top sides of two uprights 1 that are close to each other. This device is used for the installation of anchor bolts and anchor plates, facilitating the installation of the clamp 2, the uprights 1 with hanging points that are mechanically connected to the clamp 2, and the steel wire rope 3 connecting the uprights 1. This device provides safety protection for construction workers during the anchor bolt and anchor plate installation process in the foundation installation stage, representing an innovation compared to traditional methods. Two flexible ropes 4 are fixedly connected between two uprights 1. Adjacent uprights 1 are connected by flexible ropes 4 to form a safety fence.

[0029] Specifically, the side wall of the upright 1 has an insertion hole 10. A connecting block 5 is fixedly connected to the inside of the clamp 2. An insertion rod 6 is slidably connected inside the connecting block 5. The size of the insertion rod 6 matches the size of the insertion hole 10. The insertion rod 6 is inserted into the inside of the insertion hole 10, thereby completing the fixation between the upright 1 and the clamp 2. A retaining ring 8 is fixedly connected to the side wall of the insertion rod 6, and a stop block 7 is fixedly connected to the end of the insertion rod 6. The stop block 7 and the retaining ring 8 prevent the insertion rod 6 from slipping out of the inside of the connecting block 5. A spring 9 is fitted on the surface of the insertion rod 6. The two ends of the spring 9 are fixedly connected to the retaining ring 8 and the connecting block 5, respectively. The retaining ring 8 is driven by the elastic force of the spring 9 to push the insertion rod 6 into the inside of the insertion hole 10. A positioning block is fixedly connected to the surface of the connecting block 5, and a retaining frame 12 is slidably connected inside the positioning block. The retaining frame 12 inside the sliding fixing block 11 is supported on the side of the stop block 7 near the connecting block 5, thus enabling the support of the inserted rod 6 after it is lifted. The retaining frame 12 has a rectangular ring structure. The rectangular ring structure of the retaining frame 12 prevents it from sliding out of the fixing block 11.

[0030] Working principle: When it is necessary to install the upright 1 between the clamp 2 and the fixture, first pull the stop block 7 to pull out the insertion rod 6 a certain distance. Then slide the retaining frame 12 inside the fixing block 11 to support the retaining frame 12 on the side of the stop block 7 near the connecting block 5. The rectangular ring structure of the retaining frame 12 prevents it from sliding out from inside the fixing block 11. At this time, the insertion rod 6 can be supported after being lifted. After the upright 1 is inserted into the inside of the clamp 2, when the insertion hole 10 on the upright 1 moves to the position corresponding to the insertion rod 6, the retaining frame 12 located on the surface of the stop block 7 is pulled out. At this time, the retaining ring 8 will be springed by the spring 9. The force drives the insertion rod 6 to be inserted into the inner side of the insertion hole 10, thereby completing the fixing work between the upright 1 and the clamp 2, and installing the upright 1 on the clamp 2. The steel wire rope 3 at the top of the upright 1 provides a hanging point for the safety belt. Adjacent uprights 1 are connected by soft ropes 4 to form a safety guardrail. This device is used for the installation of anchor bolts and anchor plates, which facilitates the installation of clamp 2, the upright 1 with hanging points that are mechanically connected to clamp 2, and the steel wire rope 3 connecting the uprights 1. This device provides safety protection for construction workers in the anchor bolt and anchor plate installation process during the basic installation stage. Compared with the traditional method, it is an innovation.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
