[0021] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0022] like Figure 1-3 As shown, an embodiment of the utility model provides a wellhead observation auxiliary device, which mainly includes a support seat 1, a mounting seat 2 and a pulley 3, wherein the support seat 1 has two, and the two support seats 1 are symmetrically arranged, and the two ends of the mounting seat 2 are respectively connected to the top of a support seat 1, and the mounting seat 2 is connected to the two support seats 1 to form a "door" shape, and a plurality of pulleys 3 are connected and installed on the bottom of the mounting seat 2.

[0023] Specifically, the support seat 1 includes a longitudinal first support rod 11, the top of the first support rod 11 is bent 90° to form a second support rod 12, and the connection between the first support rod 11 and the second support rod 12 is a rounded transition, and the end of the first support rod 11 away from the second support rod 12 is connected to and installed with a fixed plate 14, and the fixed plate 14 is used to fix the support seat 1 to the ground; the end of the second support rod 12 away from the first support rod 11 is connected to and installed with a first connecting flange 13, and the first connecting flange 13 is used to be connected and installed with the mounting seat 2.

[0024] The mounting base 2 includes a first horizontal connecting rod 21 and a second connecting rod 22 longitudinally connected to the middle of the first connecting rod 21. Second connecting flanges 23 are installed at both ends of the first connecting rod 21. The second connecting flange 23 is used to be connected and installed with the support base 1 (specifically, the second connecting flange 23 is connected to the first connecting flange 13 by bolts); the second connecting rod 22 is connected and installed with a third connecting flange 24 at one end away from the first connecting rod 21. The third connecting flange 24 carries the mounting pulley 3, and when the wellhead observation auxiliary device of the utility model is assembled and installed at the wellhead, the third connecting flange 24 is vertically downward toward the wellhead.
