Description

Technical Field

[0001] The present invention relates to the sliding field of rapid installation of membrane structures, and more particularly to a sliding system for facilitating rapid installation of membrane materials. Background Art

[0002] The typical installation process for steel tube truss membrane structures involves four steps. The first step is to fold the rectangular membrane into a narrow strip using a fan-shaped folding method. This is then folded into a short rectangular strip using the same method and transported to the installation site by transport vehicle. The second step is to crane the short rectangular membrane to the base of the truss. The membrane is then stretched along the folds from the bottom of the truss to the top, securing the membrane at both ends. The third step is to secure one long side of the membrane to the truss chord. A winch, pulley, and clamping system are then used to stretch the membrane horizontally from the top of the truss to the bottom, securing it after it reaches the next span of the truss chord. The fourth step is to tension the membrane from the top of the truss to the bottom. However, in the third step of this method, when the membrane material is stretched horizontally, it is usually necessary to use two sets of winches, pulleys, and cable clamps to continuously stretch it horizontally from a high point to a low point. Each time the membrane material is stretched, the longitudinal extension length is relatively short. After the membrane material is horizontally positioned, the position of the splint and pulleys must be repeatedly adjusted manually at high altitude. At the same time, since the membrane material needs to be tensioned after being stretched, the total number of tensioning times increases, and the overall installation efficiency is low. This method consumes a lot of labor when folding the membrane material into a rectangular shape using a fan-shaped folding method, and the folding time is long. During installation, workers need to constantly adjust the position of the cable clamps and pulleys and repeatedly tension and tighten them. The winches and tensioners take a long time, requiring a large number of people to work at high altitudes, the operation time is long, the safety risks are greater, the installation efficiency is low, and the installation cost is increased.

[0027] like Figure 1 As shown, a preferred embodiment of the present invention provides a sliding system for facilitating the rapid installation of membrane materials, comprising:

[0028] A main shaft 100, a rectangular film material 110 is rolled onto the main shaft 100, wherein one end of the rectangular film roll is fixed to the surface of the main shaft 100; and

[0029] There are two sleeves 200, which are respectively sleeved on both ends of the main shaft 100, and the rectangular film is clamped between the two sleeves 200. At least two bearings 300 are arranged side by side between the sleeve 200 and the main shaft 100. The inner ring of the bearing 300 is sleeved outside the main shaft 100, and the outer ring of the bearing 300 is sleeved inside the sleeve 200; a lifting ear 400 is provided on the outside of the sleeve 200.

[0030] The installation of the rectangular membrane 110 typically proceeds in three stages: first, the membrane is rolled into the sliding system, then hoisted, secured, and tensioned. The membrane is 55 meters long and 12 meters wide. The short edge of the rectangular membrane is manually wound into the sliding system along a main shaft 100, a hollow steel tube 13,000 mm long, 100 mm outer diameter, and 10 mm thick. Two bearings 300 are located at each end of the main shaft 100. Bearings 300 have an inner diameter of 100 mm and an outer diameter of 140 mm, and each weighs approximately 1.5 kg. The outer rings of the bearings at each end are fitted with sleeves. Sleeves 200 are hollow steel tubes 250 mm long, 140 mm inner diameter, and 10 mm thick, and each sleeve weighs 9.4 kg. During the hoisting and fixing process, the steel wire rope is tied to the sleeve 200 and then hoisted to the top of the truss. After opening the membrane material port, the short side of the membrane material is fixed to the top of the truss. Then, it is lowered to the bottom of the truss and the other short side of the membrane material is fixed to the bottom of the truss. At this time, the crane can be evacuated from the site. Finally, when tensioning, the operator can tension the long side of the membrane material from the top of the truss downwards.

[0031] In a preferred embodiment of the present invention, a limiting plate 500 is provided at one end of the sleeve 200 close to the rectangular film roll. A limiting plate weighing about 1 kg is provided on the inner side of the sleeve to limit possible inward displacement of the sleeve.

[0032] In a preferred embodiment of the present invention, the sliding system for facilitating the rapid installation of membrane materials further comprises: a lifting lug 400 is provided on the outer surface of the sleeve 200 for tying a steel wire rope during lifting.

[0033] In a preferred embodiment of the present invention, the sliding system for facilitating rapid installation of membrane materials further includes two brackets 600, respectively mounted at both ends of the main shaft 100. The top end of each bracket 600 is connected to the sleeve 200, and a base 700 is mounted at the bottom of each bracket 600. The height of each bracket 600 is adjustable.

[0034] In the above technical solution, the entire sliding system is supported by the bracket 600, and the membrane material can be more conveniently stretched without the need for hoisting. Moreover, the height of the bracket 600 is adjustable, and the height of the bracket 600 can be adjusted according to actual conditions to achieve the stretching of the membrane material, thereby avoiding the inconvenience of stretching the membrane material due to the incompatibility of the bracket height.

[0035] In a preferred embodiment of the present invention, a hydraulic rod 800 and running wheels 900 are mounted below the base 700. The hydraulic rod 800 can be extended to a minimum length L1 and a maximum length L2. The height of the running wheels 900 is between L1 and L2. When the hydraulic rod 800 is extended to L1, the bracket 600 is supported on the ground by the running wheels 900. When the hydraulic rod 800 is extended to L2, the bracket 600 is supported on the ground by the hydraulic rod 800. To maintain balance, the number of hydraulic rods and running wheels must be at least three.

[0036] In the above technical solution, it is taken into account that the sliding system sometimes needs to be moved and sometimes needs to be fixed for use. When it needs to be moved, when the length of the hydraulic rod 800 is extended to L1, the bracket 600 is supported on the ground by the walking wheels 900. At this time, the walking wheels 900 can be rotated to drive the entire equipment to move. When it needs to be fixed for use, when the length of the hydraulic rod 800 is extended to L2, the bracket 600 is supported on the ground by the hydraulic rod 800 to achieve the fixation of the entire equipment.

[0037] In a preferred embodiment of the present invention, a built-in capsule 310 is fixedly disposed within the spindle 100. The shape of the built-in capsule 310 is consistent with the inner cavity shape of the spindle 100, and the outer wall of the built-in capsule 310 is in contact with the inner wall of the spindle 100. The built-in capsule 310 is hollow and filled with a sponge block 320 soaked in lubricating oil. The spindle 100, the inner ring 301 of the bearing 300, and the corresponding portions of the built-in capsule 310 are each provided with an oil outlet 330 for the lubricating oil to overflow. When the lubricating oil in the sponge block 320 overflows excessively, the lubricating oil will overflow from the oil outlet 330 of the spindle 100 into the space between the inner ring 301 and the outer ring 302, providing a good lubricating effect for the ball bearings.

[0038] In a preferred embodiment of the present invention, the corresponding parts of the main shaft 100 and the built-in capsule 310 are respectively provided with openings 340, one end of the connecting rod 350 is connected to the pressure plate 360, and the other end passes through the opening 340 and extends into the connecting plate 370 in the built-in capsule 310, the connecting plate 370 is arranged on the upper end surface of the sponge block, and the opening 340 is located at the top of the built-in capsule 310, the oil outlet 330 is located at the bottom of the built-in capsule 310, one end of the pressure plate 360 is rotatably hinged to the outer surface of the inner ring of the bearing 300, and the other end is connected to the outer surface of the inner ring of the bearing 300 through a spring 380, and the pressure plate 360 is arranged to be inclined upward along the rotation direction of the bearing 300.

[0039] In the above technical solution, when the bearing 300 rotates, the inner ring of the bearing 300 and the main shaft 100 are fixedly connected, and there is no relative rotation between the two. The outer ring of the bearing 300 rotates relative to the inner ring. During the rotation, the balls 390 between the inner ring and the outer ring will also rotate. During this process, the balls 390 will squeeze the pressure plate 360. At this time, the connecting rod 350 will move downward, so that the connecting plate 370 will squeeze the sponge block 320, so that the lubricating oil in the sponge block 320 will be squeezed out from the oil outlet 330 into the space between the inner ring and the outer ring, which has a good lubricating effect on the balls.

[0040] In a preferred embodiment of the present invention, the built-in capsule 310 is provided with an oil filling port to facilitate the injection of lubricating oil during subsequent use.

[0041] In a preferred embodiment of the present invention, the top of the sponge block is flat, the connecting plate 370 and the flat end area of the sponge block are consistent, which is convenient for squeezing, and a sealing ring is provided at the opening 340 of the built-in capsule 310 to prevent lubricating oil from overflowing from the opening.

[0042] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
