Description

Technical Field

[0001] This utility model belongs to the field of membrane installation technology, specifically relating to a membrane installation tension adjustment component. Background Technology

[0002] The installation of architectural membrane fabric requires preliminary preparations such as site cleaning, membrane fabric inspection, preparation of tools and equipment, erection of installation platform, and verification of dimensions. Then, the membrane fabric is unfolded in sequence, and the membrane material and cables are fixed with clamps. Tensioning is a key step and requires the use of appropriate tensioning and adjustment equipment.

[0003] The patent specification with publication number CN219280912U discloses a membrane tensioning and fixing device, including: a circular tube; an adjusting plate that extends linearly along the axial direction of the circular tube; multiple U-shaped grooves that are evenly distributed on both sides of the adjusting plate and staggered with each other, with all groove openings facing outwards; a screw rod, one end of which passes through the bottom of the U-shaped groove and the adjusting plate in sequence and is fastened with an adjusting nut, the other end of the screw rod is provided with a pressure plate, the inner side of the pressure plate and the U-shaped groove form a membrane edge strip clamping cavity, and a positioning pin is also inserted in the middle of the screw rod;

[0004] This type of membrane tensioning device involves pulling the tensile membrane between two circular tubes. The membrane's side strips sequentially enter multiple membrane side strip clamping cavities. An adjusting nut is installed at the free end of the lead screw, and an electric wrench with a pre-set torque is used to tighten the adjusting nut. The lead screw drives the pressure plate to squeeze the membrane's side strips, thus completing the fixing and tensioning of the tensile membrane. The drawback of this technical solution is that although the device can perform secondary tightening of the membrane fabric during the tightening process, the tension value of the membrane fabric needs to be within a certain range to achieve the best installation effect. After the tensioning is completed, the device cannot effectively know the tensile force on the membrane fabric, which means it cannot determine whether the final tensioning has brought the membrane fabric to its optimal tension state.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a membrane installation tension adjustment component, and the technical problem to be solved is as follows: After the existing membrane installation device is used, it is impossible to effectively know the tensile force value of the membrane, which makes it impossible to determine whether the installed membrane is in the optimal tension state.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A membrane fabric installation tension adjustment assembly includes a clamping mechanism comprising multiple clamping members. A clamping plate is installed between the bottom ends of each clamping member. A pull rope is fixedly connected to the bottom end of the clamping plate. A pull ring is fixedly connected to the bottom end of the pull rope. A tension detection mechanism is slidably connected to the middle of the pull rope. The tension detection mechanism is used to detect the tension force on the pull rope. A rope winding mechanism is installed on one side of the tension detection mechanism. The rope winding mechanism is used to wind up the rope in one direction and adjust the tension force on the tension detection mechanism.

[0016] As a further embodiment of this utility model: the side of the pull rope closest to the clamping plate is an isosceles triangle.

[0017] The beneficial effects of this utility model are:

[0018] By installing a tension detection mechanism on one side of the clamping mechanism and a rope winding mechanism on the other side of the tension detection mechanism, the rope winding mechanism can tension the membrane fabric by pulling the tension detection mechanism and the clamping mechanism during the tensioning and tightening process. The tension can be adjusted by releasing the pawl and ratchet.

[0019] Furthermore, when adjusting the tension of the membrane fabric, it is only necessary to wait until the first and second pull ropes are in a stable and static state. The tension gauge of the tension testing mechanism can measure the specific value of the tension on the membrane fabric. The purpose is to adjust the tension value of the membrane fabric to the optimal tension range, thereby improving the accuracy of tension adjustment during membrane fabric installation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 4As shown, a membrane fabric installation tension adjustment assembly includes a clamping mechanism 1, which includes three clamping members 11. A clamping plate 12 is installed between the bottom ends of each clamping member 11. A pull rope 13 is fixedly connected to the bottom end of the clamping plate 12. A pull ring 14 is fixedly connected to the bottom end of the pull rope 13. A tension detection mechanism 2 is slidably connected to the middle of the pull rope 13. The tension detection mechanism 2 is used to detect the tension on the pull rope 13. A rope winding mechanism 3 is installed on the side of the tension detection mechanism 2 away from the clamping mechanism 1. The rope winding mechanism 3 is used to wind the rope in one direction and adjust the tension of the tension detection mechanism 2.

[0028] It should be noted that multiple clamping components 11 are integrally installed on the clamping plate 12 for jointly clamping the membrane fabric used in construction. The clamping components 11 include, but are not limited to, clamping arms and clamping plates. The side of the pull rope 13 closest to the clamping plate 12 is an isosceles triangle to improve the stability of pulling the clamping plate 12. In use, only the pull rope 13 between the tension detection mechanism 2 and the clamped membrane fabric is made of flexible material with a certain deformation capability, while the other connection structures are all rigid connections. Therefore, when the pull rope 13 is in a static and stable state, the tension on the membrane fabric is equal to the tension value detected by the tension detection mechanism 2, thereby achieving accurate detection of the membrane fabric tension. When the rope winding mechanism 3 adjusts the tension, it is necessary to wait until all the pull ropes are in a static state. At this time, the final adjustment value of the tension is based on the reading of the tension detection mechanism 2.

[0029] The clamping member 11 includes a base frame 111 fixedly connected to the clamping plate 12. A cylinder 112 is installed in the middle of the base frame 111. A clamping arm 113 is fixedly connected to the top of the base frame 111. A cross frame 114 is fixedly connected to the end of the telescopic rod of the cylinder 112. A connecting rod assembly 115 is installed between the top two sides of the cross frame 114 and the adjacent clamping arm 113. A chuck 116 is installed between the top of the connecting rod assembly 115 and the top of the clamping arm 113. Therefore, the clamping member 11 can control the clamping and releasing actions of the two chucks 116 by the telescopic movement of the cylinder 112, which drives the connecting rod assembly 115. Preferably, each cylinder 112 moves synchronously.

[0030] The tensile testing mechanism 2 includes a hook 21 that is fastened to the pull ring 14. A force gauge 22 is attached to one side of the hook 21. A lock 23 is installed on one side of the force gauge 22. A pull ring 24 is fastened to one side of the lock 23. A connecting rod 25 is fixedly connected to one side of the pull ring 24. One end of the connecting rod 25 is fixedly connected to the outer frame 26. The middle part of the pull rope 13 is slidably connected to one end of the outer frame 26. One end of the outer frame 26 is fixedly connected to the rope winding mechanism 3.

[0031] It should be noted that the force gauge 22 is a digital force gauge with an LCD screen on one side of its surface to display the tension value of the pull rope 13. The force gauge 22 can be removed from the outer frame 26 by unlocking the buckle 23 and can be connected to the clamping mechanism 1 via the S-shaped hook 21. When the rope winding mechanism 3 performs the final pull on the integrated structure of the clamping mechanism 1 and the tension detection mechanism 2 after the rope winding is completed, the force measuring end of the force gauge 22 is connected to the pull rope 13, thereby detecting the tension value of the pull rope 13. After the pull rope 13 stabilizes, the tension it receives is equal to the tension value of the membrane fabric, thus realizing the function of knowing the specific tension value of the membrane fabric while tensioning the membrane fabric.

[0032] The rope winding mechanism 3 includes a second pull rope 31 fixedly connected to the outer frame 26. A rope winding shaft 32 is snapped onto one side of the pull rope 31. An outer frame 33 is rotatably connected between the two sides of the rope winding shaft 32. A ratchet 34 is fixedly connected to one end of the rope winding shaft 32. A pawl 35 is rotatably connected to the ratchet 34. The ratchet 34 and the pawl 35 are snapped together. A rotating handle 36 is installed at the other end of the rope winding shaft 32.

[0033] A return spring is built between the outer frame 33 and the pawl 35. A rope release lever 37 is fixedly connected to one side of the pawl 35, and a side plate 38 is fixedly connected to one side of the outer frame 33. The side plate 38 is threadedly connected to two fastening bolts 39.

[0034] It should be noted that when tightening the membrane fabric, the main rope of the pre-tightening rope is the second pull rope 31. The end of the second pull rope 31 is engaged with the end of the rope winding shaft 32 located inside the outer frame 33. The rope is wound up by rotating the handle 36. When the tension detection mechanism 2 and the rope winding mechanism 3 are pulled together to the point where the membrane fabric is installed with the building, the handle 36 is rotated to tighten the membrane fabric. At this time, the pawl 35 is always engaged with the outer teeth of the ratchet 34 under the pull of the return spring. Therefore, when the spring force of the second pull rope 31 rebounds, the inner teeth of the ratchet 34 cannot return because they are abutted by the pawl 35. The spring mechanism enables unidirectional winding of the second rope 31. When both the second rope 31 and the first rope 13 are in a stable and static state, the tension on the membrane can be measured by the tension value displayed by the force gauge 22. When it is necessary to adjust the tension value, the release lever 37 can be manually moved to disengage the pawl 35 from the ratchet 34. Therefore, the winding mechanism 3 can flexibly control the tension of the membrane. That is, the device not only realizes the membrane tensioning function, but also effectively adjusts the specific tension value of the membrane to match the optimal tension value of the membrane for installation on the building, thereby improving the installation accuracy.

[0035] In addition, the rope winding mechanism 3 can be used to attach the side plate 38 to the aluminum alloy plate used for membrane installation by unfastening the two fastening bolts 39, and then tightening the fastening bolts 39 to facilitate the rotation of the handle rod 36.

All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
