DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0023] Refer to Figures 1-4, A portable tripod suitable for wellhead fire fighting and rescue, including a top plate 1 and a mounting plate 6. The mounting plate 6 is a circular structure. A support is provided at the bottom of the mounting plate 6. A pulley 8 is provided in the middle of the bottom end of the mounting plate 6. The pulley 8 is installed on the support. Connecting blocks 9 are respectively provided on both sides of the support. The connecting block 9 is an L-shaped structure. An installation ring 10 is provided between the two connecting blocks 9. A conduit 11 is provided inside the installation ring 10. The conduit 11 is located below the pulley 8.
[0024] The conduit 11 is fixedly installed below the pulley 8 through the connecting block 9 and the installation ring 10. Then, the sling is passed through the conduit 11, and the sling is guided through the dedicated conduit 11, making the lifting path of the sling clearer and more controllable, and reducing the deviation and swing caused by external interference.
[0025] A rectangular block 102 is provided at the top of the top plate 1. A jack 101 is opened at the bottom of the top plate 1. The jack 101 extends into the rectangular block 102. Limiting holes 103 are opened on both sides of the rectangular block 102. The limiting holes 103 are communicated with the jack 101. A pressing block 104 is provided inside the limiting holes 103.
