Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety devices, in particular to an anti-falling double safety device. Background Art
[0002] In many engineering construction fields or maintenance sites, people often find it difficult to move the position of larger and thicker components, so lifting rods are needed to assist in splicing the workpieces, and the lifting rods are used to assist in lifting the equipment and then moving it;
[0003] Specifically, when the lifting rod is installed, the lifting rod structure is connected by means of mutual threaded connection between nuts. The position of the lifting rod is limited by tightening the nuts. At the same time, a pulling force is provided to the lifting rod to drive the equipment to lift. However, during the upward movement of the lifting rod, it will be subjected to forces in different directions, and the forces in different directions will cause the lifting rod to vibrate. When the lifting rod is subjected to repeated vibrations, the connection between the tightening nuts will become loose. At the same time, the lifting rod is easily damaged and the threads will slip due to the instantaneous overload caused by the up and down vibrations. Subsequently, the lifting rod will easily fall off due to the load. When the lifting rod falls off, it will cause a safety accident. For this reason, we have proposed a double anti-fall safety device. Utility Model Content
[0004] In view of the shortcomings of the existing anti-falling double safety device, the utility model provides an anti-falling double safety device, which has the advantage of having a clamping device installed on the outside of the lifting rod, and the clamping device is installed on the outside of the load mounting plate through a base. That is, after the clamping device limits the position of the lifting rod, the clamping device is prevented from vibrating and causing the nut to loosen, thereby solving the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical solution: an anti-falling double safety device comprises a load mounting plate, an internal movably sleeved load connector of the load mounting plate, an upper end of the load connector is mounted with a nut, an internal thread of the nut is sleeved with a lifting rod, an upper portion of the load mounting plate is mounted with a base, a top end of the base is fixedly connected with a clamping device, a side of the clamping device is mounted with a first fastening bolt, an external portion of the lower end of the clamping device is fixedly connected with an inclined plate, an external portion of the inclined plate is sleeved with an auxiliary positioning plate, a middle portion of the auxiliary positioning plate is fixedly connected with a round sleeve, and an internal movably sleeved slide rail of the round sleeve is internally connected with a slide rail.
[0006] Preferably, the load mounting plate is mounted on the upper part of the equipment by fastening bolts, and the load connector is arranged inside a groove opened at the lower end of the load mounting plate.

[0010] Preferably, the middle portion of the circular sleeve is disconnected, and the slide rail is arranged outside the disconnected portion.
[0011] Preferably, the outer portion of the inclined plate is arc-shaped, the inner side of the auxiliary positioning plate is fitted to the outer portion of the arc-shaped surface, and the lower end of the auxiliary positioning plate is mounted on the outside of the equipment by fastening bolts.
[0012] Compared with the existing anti-falling double safety device, the utility model has the following beneficial effects:
[0013] 1. The double safety device against falling off has a base installed on the upper part of the load mounting plate by fastening bolts. At the same time, the base drives the clamping device to be set at the position of the lifting rod. The clamping device limits the position of the lifting rod. When the threaded connection between the lifting rod and the load connector fails and the load falls, the friction between the clamping device and the lifting rod and the limiting effect of the nut on this mechanism can prevent the load from falling off, thereby improving the safety of equipment production.
[0014] 2. The double safety device against falling off is configured such that after the clamping device is sleeved on the outside of the lifting rod, an auxiliary positioning plate is sleeved on the outside of the load mounting plate. The auxiliary positioning plate fits on the outside of the inclined plate and adjusts the position of the slide rail inside the circular sleeve at the same time, driving the two sets of circular sleeves to be clamped and limited, thereby improving the stability when the circular sleeves are spliced. After the auxiliary positioning plate limits the outside of the clamping device, the position of the clamping device is prevented from being offset. BRIEF DESCRIPTION OF THE DRAWINGS
