Description

Technical Field

[0001] The invention relates to the field of hoisting equipment, in particular to a fan hoisting anti-slip device. Background Art

[0002] Fan is the customary abbreviation for gas compression and gas delivery machinery in my country. The fan usually refers to ventilators, blowers, compressors and Roots blowers, but does not include positive displacement blowers and compressors such as piston compressors. It converts the rotating machinery into gas pressure energy and kinetic energy and delivers the gas.

[0003] Wind turbine hoisting is an important part of wind power engineering. With the rapid development of the wind power industry in recent years, major safety accidents during hoisting have also occurred frequently. When hoisting a wind turbine, a pull rope can be used to lift the supporting platform and the wind turbine, but some supporting platforms are relatively simple. If the pull rope breaks, the supporting platform and the wind turbine will slide down, causing unnecessary harm. At the same time, some supporting platforms cannot effectively clamp and fix the wind turbine when supporting it. Therefore, it is necessary to propose a wind turbine hoisting anti-slip device. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a fan hoisting anti-slip device.

[0007] Specifically, the upper surface of the support block is provided with a mounting groove in a cross shape, the inner walls of the mounting groove are slidably connected with mounting blocks, the interior of the mounting block is symmetrically provided with a positioning cavity, the inner walls of the positioning cavity are slidably connected with positioning blocks, the inner wall of the mounting groove is provided with a plurality of positioning holes equidistantly relative to the position of the positioning block, and the positioning blocks extend into the corresponding positioning holes.

[0008] Specifically, a latch hole is formed through the upper surface of the mounting block, a latch block is latched on the inner wall of the latch hole, a rubber buffer block is fixedly connected to the inner wall of the latch block, auxiliary positioning holes are formed through the two side walls of the latch block, and the positioning block extends into the auxiliary positioning hole.

[0009] Specifically, a first spring is fixedly connected to the inner wall of the cavity, and the other end of the first spring abuts against the T-shaped extrusion block.

[0012] Specifically, support columns are fixedly connected to the blind corners of the lower surface of the support block.

[0013] Beneficial effects of the present invention: (1) The fan hoisting anti-slip device described in the present invention pulls the support block and the fan upward by pulling the rope to lift the fan to the desired position. If the pull rope breaks, the pull rope separates from the rope buckle and the T-shaped extrusion block, and the first spring pushes the T-shaped extrusion block downward. The T-shaped extrusion block pushes the trapezoidal block downward, and the trapezoidal block pushes the push block outward. The push block pushes the anti-sliding block to abut against the inner wall of the fixed block, and the support block is limited and fixed. The pull rope can be reconnected with the rope buckle, so that the T-shaped extrusion block pulls the support block upward. When the pull rope breaks, the support platform can be limited and fixed to prevent the support platform from falling and causing harm to the fan and personnel. At the same time, the pull rope is refixed, and the support platform can be quickly released from the limit, thereby speeding up the transportation of the fan.

[0014] (2) The fan hoisting anti-slip device described in the present invention is characterized in that the latch block is inserted into the mounting block, and the third spring pushes the positioning block to move into the latch block. According to the size of the fan, the latch block can be pushed to abut against the outer wall of the fan. The third spring pushes the positioning block to move into the positioning hole to limit and fix the mounting block and the latch block. When disassembling, the latch block can be pulled out of the mounting block. The position of the latch block can be adjusted according to the size of the fan to avoid the pull rope breaking when hoisting the fan, causing the fan to shake randomly and causing damage to the supporting platform and the fan. At the same time, the latch block can be pulled out quickly to facilitate the hoisting of the fan. BRIEF DESCRIPTION OF THE DRAWINGS
