[0002] The crawler-type wall-climbing robot walks by being adsorbed on steel structural parts through tracks. There are multiple magnetic seat structures around the tracks. The magnetic seat structures are adsorbed on the structural parts through magnetic force and generate friction.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a magnetic seat structure, including: a seat body 10, the seat body 10 has a first cavity and a second cavity, the opening of the second cavity faces the structural member; a magnet 20, arranged in the first cavity, for adsorbing with the structural member; an anti-slip structure 30, at least a part of the anti-slip structure 30 is located in the second cavity, and the surface of the anti-slip structure 30 is exposed to the opening of the second cavity and is used to contact with the structural member.

[0026] In this solution, a special anti-skid structure 30 is provided on the seat body 10 of the magnetic seat structure. The friction coefficient between the anti-skid structure 30 and the structural member is greater than the friction coefficient between the seat body 10 itself and the structural member, thereby increasing the friction force between the magnetic seat structure and the structural member, avoiding or reducing the slipping problem of the magnetic seat structure on the structural member, and improving reliability.

[0027] The anti-skid structure 30 is made of a material with a large friction coefficient or a material with a rough surface and wear resistance. Specifically, the anti-skid structure 30 includes a rubber block 31, which is installed in the second cavity; when the rubber block 31 is not in contact with the structural member, the rubber block 31 protrudes from the surface of the seat body 10. When the seat body 10 and the rubber block 31 are in contact with the structural member, the rubber block 31 is compressed, so that it can fully contact with the structural member to increase the friction force.

[0028] The anti-slip structure 30 further includes a fastener 32, which fixes the rubber block 31 to the second cavity, thereby preventing the rubber block 31 from falling off and ensuring reliability. The shape of the rubber block 31 matches the shape of the second cavity, so that the rubber block 31 can fill the second cavity after being compressed, eliminating gaps, and making the fixation of the rubber block 31 relatively stable.

[0029] For example, the rubber block 31 and the second cavity are both cylindrical, etc. The rubber block 31 is made of a high temperature resistant and wear resistant material, such as fluororubber or silicone rubber.

[0030] like Figure 2 As shown, the fastener 32 includes a limiting section 321 and a threaded section 322 connected to each other. The limiting section 321 is located in the rubber block 31 and limits each other, so that the two are reliably connected to each other and the rubber block 31 and the fastener 32 are prevented from being separated. The bottom wall of the second cavity has an assembly hole, and the threaded section 322 is threadedly connected to the assembly hole, or the threaded section 322 passes through the assembly hole and is fixed by a nut, and the fastener 32 is reliably connected to the seat body 10 by threaded connection. During assembly, a tool similar to a compass is inserted into the rubber block 31 and drives the rubber block 31 and the fastener 32 to rotate, thereby connecting the fastener 32.

[0031] In other embodiments, the fastener 32 may also be connected to the base body 10 by means of snap connection, riveting, etc.

[0032] Specifically, the limiting section 321 is conical, and the end of the limiting section 321 with a smaller diameter is connected to the threaded section 322. The conical surface of the limiting section 321 has a plurality of convex points or concave pits, and the rubber block 31 is embedded in the limiting section 321 during injection molding. The conical structure is adopted so that the limiting section 321 cannot be disengaged from the rubber block 31. The conical surface of the limiting section 321 has a plurality of convex points or concave pits. In this way, after the rubber block 31 is injection molded, the limiting section 321 and the rubber block 31 can more reliably achieve circumferential limiting, and when the anti-slip structure 30 is disassembled and assembled, it is ensured that the rubber block 31 and the fastener 32 will not rotate relative to each other.

[0033] like Figure 1 As shown, there are two anti-skid structures 30, which are located at both ends of the seat body 10 in the length direction, and the magnet 20 is located between the two anti-skid structures 30. The two anti-skid structures 30 enhance the anti-skid effect of the magnetic seat structure.

[0034] In other embodiments, if space permits, more anti-slip structures 30 may be provided on the seat body 10 .

[0035] The seat body 10 is made of non-magnetic material, such as metal materials such as stainless steel and aluminum, or non-metallic materials with high strength and wear resistance, so as to avoid the magnetic lines of force of the magnet 20 being closed and affecting the adsorption effect with the structural parts.

[0036] The side of the seat body 10 facing the structural member has anti-skid lines 11, and the anti-skid lines 11 can be staggered convex ribs or grooves, so that the seat body 10 can increase the friction force when contacting the structural member, and improve the anti-skid effect.

[0037] Furthermore, the seat body 10 is an integrated structure, which has high strength and is easy to process. The side surfaces at both ends of the length direction of the seat body 10 are arcuate surfaces 12. In this way, the strength of the seat body 10 is enhanced by the arcuate surfaces 12, and at the same time, when encountering obstacles that are easy to get stuck, it can smoothly transition to avoid getting stuck and prevent the seat body 10 from being damaged. The overall structure is small and compact, and maintenance is convenient.

[0038] like Figure 1 As shown, the opening of the first cavity is away from the opening of the second cavity, and the magnetic base structure further includes a cover 40, which is fixedly connected to the base 10 and blocks the opening of the first cavity. The cover 40 is used to fix and protect the magnet 20.

[0039] like Figure 3 and Figure 4 As shown, the present solution also provides an adsorption track, which includes an annular chain 51 and the above-mentioned magnetic seat structure. There are multiple magnetic seat structures, and the multiple magnetic seat structures are fixed on the outer peripheral surface of the chain 51 along the circumference of the chain 51. The adsorption track and the structural parts are adsorbed by the magnetic force of the multiple magnetic seat structures.

[0040] Specifically, the adsorption crawler also includes a bracket 52 and a motor 53, a reducer 54, a driving wheel 55, and a driven wheel 56 installed on the bracket 52. The driving wheel 55 and the driven wheel 56 are both engaged with the chain 51. The motor 53 is drivingly connected to the input end of the reducer 54, and the output end of the reducer 54 is drivingly connected to the driving wheel 55. The power output by the motor 53 is transmitted to the reducer 54, and the reducer 54 drives the driving wheel 55 to rotate, and the driving wheel 55 drives the chain 51 and the driven wheel 56 to rotate, thereby realizing the crawling of the adsorption crawler on the structural member. The adsorption crawler also includes a tensioning structure, and the tensioning structure tightens the driven wheel 56, thereby tensioning the chain 51.
