[0022] Reference Figures 1-4The machine cylinder wear detector provided by the embodiment of the application comprises a walking mechanism, a camera 3 and a support 4. The walking mechanism comprises a machine body and a wheel frame. The machine body comprises end covers 11, a tube shell 12, threaded rods 13 and sliding seats 14. The tube shell 12 is provided with the end covers 11 at two ends respectively. The threaded rods 13 are rotatably connected between the two end covers 11. The end faces of the end covers 11 are provided with clearance holes 112 for corresponding regulation and control of the end portions of the threaded rods 13. The sliding seats 14 are two in number and are reversely threadedly connected with the front and rear portions of the threaded rods 13 respectively. The lower sides of the sliding seats 14 are provided with “eight”-shaped inner side wall faces. The outer wall of the sliding seat 14 corresponds to the tube shell 12. The lower side of the tube shell 12 is provided with an opening extending in the axial direction. The wheel frame is provided with two groups. Each group of the wheel frame comprises cross movable connecting rods 21, wheel rods 22 and small wheels 23. The upper ends of the cross movable connecting rods 21 of each group of the wheel frame are rotatably connected with the same side of the lower inner side wall faces of the two sliding seats 14 respectively. The lower ends of the cross movable connecting rods 21 are movably connected with the front and rear portions of the wheel rods 22 respectively. At least two small wheels 23 are mounted on each wheel rod 22. The two groups of the wheel frame are movably and adjustably mounted on the lower side of the machine body in a “eight”-shaped manner. One support 4 is mounted on the outer end face of one end cover 11. The camera 3 is adjustably mounted on the side of the support 4 away from the end cover 11. When the detector is used to detect the wear of the machine cylinder, the threaded rods 13 only need to be rotated from the end portion, i.e. the end cover 11, of the machine body to drive the two sliding seats 14 to move towards each other or away from each other, thereby driving the cross movable connecting rods 21 to extend or retract, and finally controlling the wheel frame to extend or retract from the bottom of the machine body. Meanwhile, the “eight”-shaped arrangement of the two wheel frames not only enables the overall walking mechanism to be relatively horizontally lifted and lowered, but also enables the walking mechanism to be stably stood and walked, and better adapt to the circular inner wall of the machine cylinder for adjustment. Therefore, the walking mechanism can be placed in the machine cylinder structure, and then operated from the end portion to adjust the height of the camera 3. The camera 3 only needs to be mounted on the end cover 11 at the front end of the detector and adjusted in position accordingly. The overall structure is very compact. Neither the camera 3 nor the support 4 occupies or interferes with the structure of the walking mechanism. Meanwhile, the wheel frame can be cleverly stored in a more delicate structure, thereby enabling the overall structure to reduce the space occupation to the greatest extent. The overall structure distribution is very reasonable and efficient.

[0023] Reference Figure 2 Illustratively, the sliding seat 14 is provided with a nut 141 which can be assembled and disassembled. The sliding seat 14 is threadedly connected with the threaded rod 13 through the nut 141. Preferably, the nut 141 only needs to be placed into the through hole in the sliding seat 14 from one end and locked by a screw, thereby eliminating the need for tapping operation on the sliding seat 14 during machining and facilitating assembly.

[0024] Reference Figure 2Exemplarily, two said end covers 11 are also connected with guide rods 15 parallel to said threaded rods 13, said sliding seats 14 are slidingly connected with said guide rods 15, so that the movement of sliding seat 14 is defined by the sliding cooperation of sliding seat 14 and guide rod 15, and the rotation of threaded rod 13 can more stably move sliding seat 14, and the connection between end covers 11 through guide rods 15 also has better structural strength.

[0025] With reference to Figure 2 Exemplarily, said guide rods 15 are two and symmetrically distributed on the left and right sides of said threaded rods 13, preferably guide rods 15 and threaded rods 13 are distributed in a triangular manner, so as to better utilize the three-dimensional structure of the walking mechanism and make the overall structure more firm.

[0026] With reference to Figure 2 Exemplarily, two said end covers 11 are provided with baffles 16 matching the lower opening of said tube shell 12, the axial cross-sectional shape of said baffle 16 corresponds to the inner side wall surface shape of said sliding seat 14, and said baffle 16 is provided with a limiting groove 161 corresponding to the clearance of said cross-moving connecting rod 21, the limiting groove 161 correspondingly extends along the axial direction of the tube shell 12, so as to protect the internal structure from the lower side and correspondingly limit the adjustment range of the cross-moving connecting rod 21.

[0027] With reference to Figure 2 Exemplarily, the inner side of said end cover 11 is provided with an insertion groove 111 matching the end of said baffle 16, so as to conveniently assemble and disassemble.

[0028] With reference to Figure 1 and 2 Exemplarily, said wheel rod 22 is provided with a sliding groove 221, and the lower end of said cross-moving connecting rod 21 is hingedly and slidingly connected with said wheel rod 22 and said sliding groove 221, so that the wheel frame can be quickly folded and unfolded when the cross-moving connecting rod 21 moves with the sliding seat 14, and of course the lower end of the cross-moving connecting rod 21 can also be slidingly connected with the sliding groove 221.

[0029] With reference to Figure 1 and 2 Exemplarily, a positioning rod 113 is installed on the side wall of said end cover 11, and a through hole is provided on said tube shell 12 to accommodate said positioning rod 113, so as to correspondingly position by abutting the inner wall of the barrel through the positioning rod 113, and the assembly and disassembly are convenient and easy to operate.

[0030] With reference to Figure 1 and 2For example, the bracket 4 is provided with two parallel fork rods 41, the rear side of the camera 3 is provided with a protruding block 31 matched and clamped by the fork rods 41, so that the camera 3 can be steadily moved and positioned along the fork rods 41 and locked by bolts.

[0031] With reference to Figure 1 And 2 For example, the outer end surface of each of the two end covers 11 is provided with the bracket 4, and another bracket 4 is further provided with a wire connecting end 6, and a wire tube 5 is connected between the wire connecting end 6 and the camera 3, so as to conveniently extend the wire from the camera 3 to the wire connecting end 6 in a protected manner. Preferably, the wire tube 5 is parallel to the side of the tube shell 12 and located between the alignment rods 113, so as to effectively avoid structural interference and adapt to the "8" shaped barrel structure, which is very efficient. Moreover, the connection of the camera 3, the bracket 4, the wire tube 5 and the wire connecting end 6 makes the structure of the detector more solid and the stability is further improved.

[0032] The above is only the preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present application, and these improvements and substitutions should also be considered as the protection scope of the present application.
