Technical Field

[0001] The utility model relates to the technical field of safety rope locks, in particular to a safety rope lock for photovoltaic construction. Background Art

[0002] The photovoltaic construction safety rope lock is a safety device designed specifically for the photovoltaic construction field and is widely used in high-altitude work scenarios such as roof installation, maintenance, and inspection of photovoltaic power stations. It can effectively ensure the safety of construction workers and reduce the risks of high-altitude work.

[0003] When using the safety rope lock, the hook of the lock needs to be hung on the belt of the photovoltaic construction worker to facilitate the normal function of the safety rope lock. However, during the construction worker's operation, friction will continue to occur at the connection between the hook and the belt, which will cause the hook and belt to wear and reduce their service life, and also reduce the safety performance of the safety rope lock. Utility Model Content

[0004] The utility model provides a photovoltaic construction safety rope lock device to solve the problem that during the construction workers' operation, friction will continue to be generated at the connection between the hook and the belt, which will cause the hook and the belt to wear out and reduce the service life, and also reduce the safety performance of the safety rope lock device.

[0005] The hook at two ends is hooked at two ends, and two ends of hook are positioned at the bottom of the rope, and a little on both sides of the rope sling are provided with hooking and closing.

[0006] The effect achieved by the above components is: by setting two clamping blocks, under the action of the threaded rod, the threaded rod is rotated, and the threaded rod will extend and retract on the inner wall of the extension block. During the extension and retraction process, the threaded rod will drive the clamping blocks to move synchronously until the two clamping blocks completely clamp the operator's belt, which can fix the hook and the belt, reduce the friction between the hook and the belt, and thus reduce the wear of the hook and the belt. At the same time, it can also assist in fixing the hook and the belt, reduce the pulling between the belt and the hook to a certain extent, and improve the safety performance of the safety rope lock.

[0007] Preferably, the ends of the two threaded rods that are away from each other are fixedly connected to an operating block, and the outer surface of the operating block is provided with a protrusion.

[0008] The effect achieved by the above components is: by setting the operating block, rotating the operating block can drive the threaded rod to rotate, and at the same time, the outer surface of the operating block is provided with a protrusion, which can effectively increase the friction force of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0009] Preferably, the outer surface of the threaded rod is threadedly connected with a screw hole block, and the screw hole block is arranged between the clamping block and the extension block.

[0010] The effect achieved by the above components is: by setting the screw hole block and rotating the screw hole block so that one side of the screw hole block abuts against one side of the extension block, one end of the threaded rod can be limited, which is helpful to prevent the two clamping blocks from loosening the clamping of the belt.

[0011] Preferably, a round rod is fixedly connected to one side of the clamping block, and the outer surface of the round rod is slidably connected to the inner wall of the extension block.

[0012] The effect achieved by the above components is: by setting the round rod, when the clamping block moves under the action of the threaded rod, the clamping block will drive the round rod to slide synchronously on the inner wall of the extension block, which can limit the clamping block.

[0013] Preferably, the adjacent sides of the two clamping blocks are fixedly connected with a rubber plate, and grooves are evenly formed on one side of the rubber plate.

[0014] The effect achieved by the above components is: by providing the rubber plate with grooves, the friction force on one side of the clamping plate can be increased, so that the two clamping blocks have an anti-slip effect when clamping the belt, and at the same time can provide a certain degree of protection for the belt.

[0015] Preferably, the protection device comprises a rubber ring, the outer surface of the rubber ring is inserted into the inner wall of the hanging ring.

[0016] The effect achieved by the above components is: by providing a rubber ring, the inner wall of the hanging ring can be wrapped, thereby preventing the inner wall of the metal hanging ring from constantly rubbing against the rope and possibly causing the rope to break.

[0017] Preferably, a circular hole block is symmetrically fixedly connected to the outer surface of the rubber ring, a threaded pin is inserted into the inner wall of the circular hole block, one end of the threaded pin is fixedly connected to one side of the hanging ring, and a nut is provided on the outer surface of the threaded pin.

[0018] The effect achieved by the above components is: by setting a threaded pin, inserting the threaded pin into the inner wall of the circular hole block, and then sleeved on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the circular hole block, the rubber ring and the hanging ring can be auxiliary fixed, which is helpful to prevent the rubber ring from falling off the hanging ring.

[0019] Preferably, a gasket is provided between the nut and the circular hole block, and the outer surface of the threaded pin is inserted into the inner wall of the gasket.

[0020] The effect achieved by the above components is that by providing a gasket, one side of the nut is abutted against one side of the circular hole block instead of the other side, which is helpful to prevent the nut from loosening.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the present invention, two clamping blocks are provided. Under the action of the threaded rod, the threaded rod can drive the clamping blocks to move synchronously until the two clamping blocks completely clamp the operator's belt. This can fix the hook and the belt, reduce the friction between the hook and the belt, and thus reduce the wear of the hook and the belt. At the same time, it can also assist in fixing the hook and the belt, reduce the pulling between the belt and the hook to a certain extent, and improve the safety performance of the safety rope lock.
