[0005] Preferably, a mounting hole is opened in the middle of the support plate, and a lifting rod is installed through the mounting hole.
[0006] Preferably, there are multiple support frames, which are respectively arranged on both sides of the two ends of the support plate, and two support frames parallel to each other and arranged on both sides of the end of the support plate are respectively arranged at both ends of the support plate. The middle and bottom of the multiple support frames are provided with a first support arm and a second support arm protruding outward, and the outer side of the second support arm is movably connected with a pulley.
[0007] Preferably, there are two limit rods, one ends of the two limit rods are engaged with each other and movably fixed in the middle of the lifting rod clamping block, and the limit rod and the clamping block are fixed by a shaft.
[0008] Preferably, L-shaped limiting members are provided on both sides of the limiting rod.
[0009] Preferably, a plurality of slots for the limiter to hook are provided in the middle of the guide rail from top to bottom, and limit slots for embedding pulleys are also provided on both sides of the slot.
[0010] The beneficial effects of the utility model are as follows: 1. By arranging downwardly extending support frames on both sides of the support plate and configuring the first support arm and the second support arm thereon, the overall structure is stable and reliable and can withstand a large load. The pulley installed on the outer side of the second support arm cooperates with the guide rails on both sides to form a stable guide system, effectively preventing the hoist from deflecting or tilting during operation.
[0011] 2. The lifting rod in the limit device is embedded in the middle of the support plate, and the design of the elastic steel plate and spring realizes dynamic adjustment and buffering functions. When the hoist encounters an abnormal situation, the elastic steel plate and spring can absorb part of the impact energy, reduce the direct impact force, protect the equipment from damage, and improve the safety and durability of the system. At the same time, when the upper end of the lifting rod is pulled by the rope, the lifting rod drives the limit rod to retract upward, and the limit piece is disengaged from the slot of the guide rail, making the pulling of the lifting rod smoother. When the lifting rod is stopped, the limit rod is pushed out again and opened through the rebound effect of the spring and the elastic steel plate, so that the limit pieces at both ends of the limit rod are re-embedded in the slot of the guide rail for limiting, preventing the risk of the hoist falling. The structure is simpler and more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
