Traditional sliding shoes cannot be used for a second time, so there is an urgent need for a reusable sliding shoe that can be used in the construction of steel structure trusses.

[0003] The existing technology has the following problems:

[0004] In the prior art, during the sliding construction of the steel structure truss, since the sliding shoes are connected to the steel structure truss by welding, when the sliding shoes are removed after the construction is completed, they need to be cut off from the steel structure truss, which will damage the sliding shoes. Therefore, the sliding shoes cannot be quickly disassembled and cannot be recycled. In addition, during the sliding process of the sliding shoes, the friction between the sliding shoes and the sliding rails is relatively large, which makes it very easy for the steel structure truss to get stuck when moving.

[0025] The hydraulic crawler is connected to the push ear plate 14 through a pin shaft to provide power for the sliding shoe and push the sliding shoe plate 1 to slide. A limit card plate 2 5 is provided to limit the track offset during sliding, so that the sliding shoe moves forward and backward along the track direction. An oil tank 12 is provided and filled with lubricating oil. When the sliding shoe plate 1 is in the sliding process, the lubricating oil can continuously lubricate the track, reduce the friction between the sliding shoe and the track, and make the entire steel structure truss smoother in the sliding process. When the sliding of the steel structure truss 3 is completed, the weld seam between the stiffening plate 2 and the steel structure truss 3 can be easily separated, which is convenient for the disassembly of the sliding shoe plate 1. There is no need to cut the sliding shoe plate 1. The sliding shoe plate 1 is not damaged during the entire disassembly process, thereby realizing the turnover of the sliding shoe. The pushing ear plates 14 arranged in pairs make the pushing force act above the plane where the track is located, so that the crawler, the sliding shoe device, and the track remain in the same straight line, which is conducive to improving the accuracy of sliding.

[0026] like Figure 1-Figure 4 , Figure 6 As shown, there are four pairs of stiffening plates 2, and three of them are welded to the four sides of the sliding shoe plate 1 in a pair. A chamfered corner 7 is provided at the left end of the inclined surface 13, a notch 6 is provided at the lower part of the right side of the stiffening plate 2, a chamfered corner 16 is provided at the upper part of the right side of the pushing ear plate 14, a cylindrical ear hole 15 is provided at the upper part of the front side of the pushing ear plate 14, and the position of the pushing ear plate 14 is staggered from the setting position of the stiffening plate 2.

[0027] The hydraulic crawler is connected to the ear hole 15 on the pushing ear plate 14 through a pin shaft to provide power for the sliding shoe and push the sliding shoe plate 1 to slide. The chamfered corner 16 is set to avoid stress concentration and ensure the push-pull strength of the pushing ear plate 14. The pushing ear plates 14 are arranged in pairs so that the pushing force acts above the plane where the track is located, so that the crawler, the sliding shoe device, and the track are kept in the same straight line, which is beneficial to improve the accuracy of sliding. The three stiffening plates 2 are a pair and are welded to the side of the sliding shoe plate 1 to ensure the stability of the sliding shoe plate 1 during sliding.

[0028] like Figure 1-Figure 5 As shown, a limiting clamp plate 4 is welded in the middle of the lower surface of the sliding shoe plate 1, the length of the limiting clamp plate 4 is equal to the length of the limiting clamp plate 2 5, and the width and height of the limiting clamp plate 1 4 and the limiting clamp plate 2 5 are equal, and the two limiting clamp plates 2 5 are located on the left and right sides of the limiting clamp plate 1 4, and the sliding shoe plate 1, the reinforced plate 2, the limiting clamp plate 1 4, the limiting clamp plate 2 5, and the push ear plate 14 are all made of Q355B.

[0029] By setting a limit card plate 1 4 and two limit card plates 2 5, a double limit structure can be formed, so that the sliding shoe can slide on one guide rail alone or on two parallel slide rails, which is used to limit the track offset during sliding, so that the sliding shoe moves forward and backward along the track direction.

[0030] like Figure 2-Figure 5 As shown, the oil groove 12 is located between the limit clamp plate 2 5 and the limit clamp plate 1 4, the front side of the lower surface of the oil groove 12 is inclined, and the lower surface of the slipper plate 1 is provided with three through holes 11 distributed in a linear array, and the upper ends of the through holes 11 are connected to the inner cavity of the oil groove 12, and the rear end of the inner cavity of the oil groove 12 is inserted with a rubber plug 9, and the cross-section of the rubber plug 9 is a T-shaped structure, and a plurality of anti-slip convex strips 10 are fixedly installed on the rear side of the outer surface of the rubber plug 9.

[0031] Lubricating oil is filled into the oil groove 12, and the rubber plug 9 is inserted into the oil groove 12. When the sliding shoe plate 1 is sliding, the lubricating oil drips onto the track through the through hole 11, which can continuously lubricate the track and reduce the friction between the sliding shoe and the track, so that the entire steel structure truss is smoother in the sliding process, and the anti-skid convex strip 10 plays an anti-skid role.

[0032] The working principle of the present invention is as follows: the hydraulic crawler is connected to the ear hole 15 on the push ear plate 14 through a pin shaft, providing power for the sliding shoe, pushing the sliding shoe plate 1 to slide, and a double limiting structure can be formed by setting a limiting card plate 1 4 and two limiting card plates 2 5, so that the sliding shoe can slide on a single guide rail, and can also slide on two parallel slide rails, which is used for track offset limiting during sliding, so that the sliding shoe moves forward and backward along the track direction, and an oil groove 12 and a through hole 11 are set, and lubricating oil is filled in the oil groove 12. When the sliding shoe plate 1 is sliding, the lubricating oil drips onto the track through the through hole 11, which can continuously lubricate the track and reduce The friction between the sliding shoe and the track makes the entire steel structure truss smoother during the sliding process. When the steel structure truss 3 has completed sliding, the weld between the stiffened plate 2 and the steel structure truss 3 can be easily separated, which is convenient for disassembly of the sliding shoe plate 1 without cutting the sliding shoe plate 1. The sliding shoe plate 1 is not damaged during the entire disassembly process, thereby realizing the turnover of the sliding shoe. The rounded corners 16 are arranged to avoid stress concentration and ensure the push-pull strength of the pushing ear plate 14. The pushing ear plates 14 are arranged in pairs, so that the pushing force acts above the plane where the track is located, so that the crawler, the sliding shoe device, and the track remain in the same straight line, which is beneficial to improving the accuracy of sliding.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
