DETAILED DESCRIPTION

[0027] The utility model will be further explained in detail in combination with the drawings.

[0028] Example 1:

[0029] Reference Figure 1 , Figure 2 , Figure 4 , a kind of assembly type tower crane guardrail, including first guardrail 1 and second guardrail 2, second guardrail 2 is close to the side of first guardrail 1 And the side of first guardrail 1 away from second guardrail 2 are welded with connecting block 7, first guardrail 1 and second guardrail 2 inside away from connecting block 7 side are bolted with spring 4, the bottom of spring 4 is fixedly connected with the sliding block 5 of first guardrail 1 and second guardrail 2 sliding connection respectively, the side of sliding block 5 surface away from connecting block 7 is welded with pull block 8, the bottom of pull block 8 is welded with square plug-in rod 6, the inside of connecting block 7 is provided with square insertion slot 16 with square plug-in rod 6 sliding insertion.The spring 4 of drive square plug-in rod 6 and connecting block 7 are mutually inserted by the elastic force of spring 4, so that first guardrail 1 and second guardrail 2 are mutually clamped and assembled together.Not only convenient for the disassembly of tower crane guardrail, and the disassembled guardrail can also be recycled and reused, thereby improving the practicality of tower crane guardrail.

[0030] Reference Figure 4 The surface of pull block 8 is provided with anti-skid stripe.Increase the friction of surface, it is convenient to pull up pull block 8 and drive square plug-in rod 6 to slide out the inside of square insertion slot 16.

[0031] Reference Figure 1 , Figure 2 , the top of the first guardrail 1 and the second guardrail 2 are bolted with warning lights 14. Improve the warning effect of the guardrail, so as to warn the workers away from the tower crane.

[0032] Reference Figure 1 , the side away from each other of the first guardrail 1 and the second guardrail 2 are adhered with reflective stickers 13. The light of the engineering vehicle can be reflected, preventing collision with the guardrail when the light is not good at night.

[0033] Brief description of the use process: by pulling the pull block 8 at one end of the first guardrail 1 upwards, the pull block 8 overcomes the elastic force of the spring 4 and drives the square insertion rod 6 to move downwards. Then the second guardrail 2 is close to the first guardrail 1, and the pull block 8 is loosened, so that the sliding block 5 can drive the square insertion rod 6 to move downwards by the elastic force of the spring 4, and the square insertion rod 6 is inserted into the inside of the square insertion slot 16, so as to assemble the first guardrail 1 and the second guardrail 2 together. At the same time, only need to push the pull block 8 upwards again, so that the square insertion rod 6 slides out of the inside of the square insertion slot 16, that is, the first guardrail 1 and the second guardrail 2 are quickly disassembled and separated. And because the square insertion slot 16 of the square insertion rod 6 is a square structure, the assembly angle between the first guardrail 1 and the second guardrail 2 can only be a right angle or parallel, so that the guardrail can be assembled according to the needs and turned into a square around the tower crane base.
