[0005] The upper support plate and the lower support plate are arranged in parallel. The connecting rod is fixed between the upper support plate and the lower support plate. The upper support plate is located directly above the lower support plate. The size of the lower support plate is smaller than the through hole size at the end of the guide rod. A fixed shaft passes through the upper support plate. The two ends of the lifting lug are respectively rotatably connected to the outer side of the fixed shaft.

[0006] As a preferred technical solution of this utility model, it also includes an anti-drop component, which includes a positioning steel pipe, an opening groove, a locking rod, a stop rod, and a fixing nut;

[0007] The positioning steel pipe is vertically fixed to one end of the upper support plate, and the fixing nut is fixed to one end of the lower support plate. The positioning steel pipe is located directly above the fixing nut, and the central axis of the positioning steel pipe coincides with the central axis of the fixing nut. The locking rod is located inside the positioning steel pipe. An opening groove is formed on the outer side of the positioning steel pipe along its length. The opening of the opening groove is located at the upper end of the positioning steel pipe. A stop rod is fixed on the outer side of the locking rod. The outer diameter of the stop rod is smaller than the width of the opening groove.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 The top of is the top. Figure 2 (The preceding part is described as the foreground). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a guide rod lifting device, including an upper support plate 1, a lower support plate 2, a connecting rod 3, a fixed shaft 4, and a lifting lug 5;

[0018] The upper support plate 1 and the lower support plate 2 are arranged in parallel. The connecting rod 3 is fixed between the upper support plate 1 and the lower support plate 2, and the connecting rod 3 is located at one end between the two. The upper support plate 1 is located directly above the lower support plate 2, so that the upper support plate 1, the lower support plate 2 and the connecting rod 3 form a U-shaped structure. The size of the lower support plate 2 is smaller than the through hole size at the end of the guide rod, so that the lower support plate 2 can pass through the through hole at the end of the guide rod. A fixed shaft 4 passes through the upper support plate 1, and the fixed shaft 4 passes through the upper support plate 1 vertically in the front-back direction. The two ends of the lifting lug 5 are rotatably connected to the outer side of the fixed shaft 4. When hoisting the guide rod, the lower support plate 2 passes through the through hole at one end of the guide rod, and then the lifting chain passes through the lifting lug 5. The guide rod is lifted by the overhead crane. When unlocking is required, the lower support plate 2 is disengaged from the guide rod by using a long rod, so as to quickly complete the removal and unloading of the guide rod and improve work efficiency.

[0019] Furthermore, in order to prevent the guide rod from detaching from the lifting device during the lifting process, the lifting device also includes an anti-detachment component 7, which includes a positioning steel pipe 71, an opening slot 72, a locking rod 73, a stop rod 74, and a fixing nut 75.

[0020] The positioning steel pipe 71 is vertically fixed to one end of the upper support plate 1, and the fixing nut 75 is fixed to one end of the lower support plate 2. The positioning steel pipe 71 is located directly above the fixing nut 75, and the central axis of the positioning steel pipe 71 coincides with the central axis of the fixing nut 75. The locking rod 73 is located inside the positioning steel pipe 71. An opening groove 72 is opened on the outer side of the positioning steel pipe 71 along its length. The opening position of the opening groove 72 is located at the upper end of the positioning steel pipe 71. A stop rod 74 is fixed on the outer side of the locking rod 73. The outer diameter of the stop rod 74 is smaller than the width of the opening groove 72. After the lower support plate 2 passes through the through hole at the end of the guide rod, the locking rod 73 falls through the central hole of the fixing nut 75. Under the limiting action of the opening groove 72, the guide rod is limited and fixed, preventing the guide rod from slipping during hoisting.

[0021] To improve the connection between the positioning steel pipe 71 and the fixing nut 75, the positioning steel pipe 71 is connected to the upper support plate 1 and the fixing nut 75 is connected to the lower support plate 2 by welding.

[0022] To improve the structural strength of the entire lifting device, the upper support plate 1, the lower support plate 2, and the connecting rod 3 are integrated into one structure, and all three are made of steel.

[0023] To facilitate workers using long rods to move the lifting device and detach the lower support plate 2 from the lifting rod, an auxiliary frame 6 is welded to one side of the connecting rod 3.

[0024] When in use: When it is necessary to hoist the guide rod, the lower support plate 2 passes through the through hole at the end of the guide rod, and then the locking rod 73 is moved so that the lower end of the locking rod 73 passes through the fixing nut 75, and the lifting chain passes through the lifting lug 5 on the upper support plate 1. The lifting chain is then lifted by the overhead crane to realize the transportation of the guide rod.

[0025] After the lifting rod is delivered to the position, the lifting chain is in a slack state. Then, the stop rod 74 is lifted by the long rod and rotated so that the stop rod 74 falls on the upper end of the positioning steel pipe 71. Then, the lower support plate 2 is moved so that the lower support plate 2 is disengaged from the guide rod, thereby unlocking the guide rod.
