[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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.

[0022] Refer to Figures 1 - 3, A pipeline crawler, including a body 1, a mounting plate 2 is fixedly connected to the body 1, a mounting hole 3 is opened on the mounting plate 2, and a mounting rod 4 corresponding to the mounting hole 3 is slidably sleeved in the mounting hole 3. The mounting hole 3 is composed of a circular hole and a rectangular hole, and the mounting rod 4 is composed of a cylindrical rod and a rectangular plate. Due to the special structures of the mounting hole 3 and the mounting rod 4, for the mounting rod 4 to be detached from the mounting hole 3, precise alignment is required to complete the disassembly and assembly operation of the mounting rod 4;

[0023] A lighting lamp 5 is fixedly connected to the mounting rod 4, and the lighting lamp 5 is fixedly connected to one end of the mounting rod 4 away from the mounting plate 2;

[0024] A fixing mechanism for fixing and limiting the lighting lamp 5 is arranged on the body 1. Through the fixing mechanism, the position of the lighting lamp 5 can be further fixed. For details, refer to the attached Figure 2 - attached Figure 3 , The fixing mechanism includes a guiding sliding groove 6 opened on the body 1. A guiding slider 7 and a spring 8 are welded in the guiding sliding groove 6. The guiding slider 7 is slidably sleeved in the guiding sliding groove 6, and the spring 8 is welded at the front end position of the guiding sliding groove 6. The guiding sliding groove 6 can guide and limit the guiding slider 7, which helps to ensure the stability of the guiding slider 7 when moving horizontally in the guiding sliding groove 6. Due to the elastic force of the spring 8, the guiding slider 7 can be reset when not being pulled;

[0025] A contact cam 9 that is movably abutted against the guiding slider 7 is fixedly sleeved on the mounting rod 4. The contact cam 9 is an elliptical structure. It should be noted that: the contact cam 9 and the guiding slider 7 are always movably abutted;

[0026] A fixing rod 10 that penetrates the mounting rod 4 is fixedly connected to the guiding slider 7. A fixing hole for slidably sleeving the fixing rod 10 is opened on the mounting rod 4. It should be noted that: the initial state of the contact cam 9 is the horizontal state when the mounting rod 4 corresponds to the mounting hole 3. When rotating more than 45° in the horizontal state, the fixing rod 10 enters the fixing hole. The fixing hole is a circular groove structure, and the diameter of the circular groove is correspondingly set with the fixing rod 10, so that the fixing rod 10 can move vertically in the circular groove, thereby avoiding the movement interference of the fixing rod 10 on the rotation of the mounting rod 4. Through the movable abutment between the inner wall of the fixing hole and the outer wall of the fixing rod 10, the horizontal position deviation of the mounting rod 4 can be avoided, which helps to ensure the stability of the mounting rod 4. And when the fixing hole corresponds to the fixing rod 10, the rectangular plate part of the mounting rod 4 is movably abutted against the mounting plate 2.

[0027] The functional principle of the present utility model can be elaborated through the following operation methods:

[0028] Pull the guiding slider 7 to move in the guiding chute 6, squeeze the spring 8, the mounting rod 4 enters the mounting hole 3, release the guiding slider 7, under the elastic force of the spring 8, the guiding slider 7 is movably abutted against the abutting cam 9, rotate the mounting rod 4, the mounting rod 4 drives the abutting cam 9 to rotate 90°, under the elastic force of the spring 8, the guiding slider 7 drives the fixing rod 10 to enter the fixing hole;

[0029] When it is necessary to disassemble the illuminating lamp 5, rotate the mounting rod 4, the mounting rod 4 drives the abutting cam 9 to rotate 45°, at this time the guiding slider 7 is squeezed by the abutting cam 9 to drive the fixing rod 10 to disengage from the fixing hole, continue to rotate the mounting rod 4, the mounting rod 4 drives the abutting cam 9 to rotate 45°, at this time pull out the mounting rod 4, thus completing the disassembly work of the illuminating lamp 5.
