Description

Technical Field

[0001] This invention relates to a turnbuckle quick-adjustment wrench. Background Technology

[0002] During construction, protective scaffolding is often erected for safety reasons, particularly for multi-story and high-rise buildings, where cantilevered scaffolding is frequently required. According to construction specifications, the steel beams at the bottom of the cantilevered scaffolding must be unloaded using wire ropes. Currently, the common practice is to insert one end of the wire rope into the steel beam and the other end into a pre-drilled hole in the main structure, securing both ends with wire rope clips. The disadvantages of this method are: each unloading wire rope must be a single, continuous rope, which is inconvenient; the wire rope has a certain rigidity, making it difficult to tighten it all at once; the wire rope clips at both ends make it difficult to retighten if loosened by external forces; and the unloading wire ropes may not be fully taut after installation, theoretically increasing the deformation of the load-bearing steel beams and raising safety risks. To address this, a structural method for securing and unloading the wire rope was adopted. The two ends of the wire rope are fixed to the ends of the steel beam and the main structure, respectively. The wire rope is broken in the middle, with a pre-installed turnbuckle position. The two sections of the wire rope are connected together using the turnbuckle. After both ends are fixed, the wire rope is tightened by adjusting the turnbuckle. This method facilitates maintenance and management during construction. However, the current turnbuckle adjustment is only done manually by rotating a wrench or roller half a turn. In a large construction site, many wire ropes are used, making this method labor-intensive, inefficient, and time-consuming, thus lacking efficiency and economy. Summary of the Invention

[0003] This invention proposes a quick-adjustment wrench for turnbuckles. After the turnbuckle is installed, with both ends of the turnbuckle fixed, the quick-adjustment wrench can be clamped perpendicular to the turnbuckle direction and used to lock the adjusting nut in the middle of the turnbuckle. By quickly rotating the adjusting nut, the turnbuckle can be loosened or tightened. The quick-adjustment wrench can quickly adjust the turnbuckle to achieve the effect of tightening the steel wire ropes at both ends of the turnbuckle. When it is necessary to loosen the turnbuckle, it can be quickly adjusted in the opposite direction to a state where no force is applied.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A quick-adjusting turnbuckle wrench includes a square handheld housing. Bevel gears are mounted on the bottom and side plates of the housing. The bevel gear on the side plate is called the driving bevel gear, and the bevel gear on the bottom plate is called the driven bevel gear. The driving bevel gear has a rotating shaft, which is rotatably fixed to the side plate via bearings. A rotating interface for connecting to a pistol drill is located on the outer side of the side plate. The driving and driven bevel gears mesh within the square housing. The outer end of the toothed portion of the driven bevel gear is an outwardly protruding annular platform. An arc-shaped slide rail groove is provided on the bottom plate, and the driven bevel gear is rotatably engaged in the arc-shaped slide rail groove via the annular platform. A slide rail groove is provided on the other side plate of the square housing opposite to the side plate where the active bevel gear is located. A through slot is provided on the central plane surrounding the tooth profile of the driven bevel gear. A notch block that can be opened is provided on the tooth profile of the driven bevel gear and the annular platform corresponding to the through slot. The notch block is connected to the circular platform by a shaft pin. A turnbuckle can be inserted into the through slot through the opened notch block. Through holes are provided on the top plate and bottom plate of the square housing corresponding to the through slot. A through vertical long slot is provided on the other side plate, which is connected to the through holes of the top plate and bottom plate. A transverse slot is provided on the other side plate at the position corresponding to the driven bevel gear for opening the notch block.

[0006] A further aspect of the solution is that the arc-shaped slide rail groove is composed of three arc-shaped slide rail grooves, which are set at 120° angles.

[0007] A further aspect of the solution is that: the upper and lower surfaces of the arc slide rail groove are respectively provided with arc grooves at intervals, and rolling balls are provided in the arc grooves, with the rolling balls resting on the upper and lower planes of the driven bevel gear ring platform.

[0008] A further aspect of the solution is: a notch is provided in the central plane surrounding the tooth profile of the driven bevel gear, and a replaceable slot module is provided in the notch, with different slot modules having different specifications of the through slot.

[0009] The solution is further described as follows: the arc slide rail groove is composed of a box bottom plate and an arc pressure plate. The arc pressure plate has a "Z" shaped cross section and the upper and lower plates of the "Z" shape are bent at right angles. The arc pressure plate is fixed to the box bottom plate with screws to form the arc slide rail groove.

[0010] A further aspect of the scheme is that the speed ratio between the driving bevel gear and the driven bevel gear is 1:1, 2:1, or 3:1.

[0011] A further aspect of the solution is that the rotary interface connected to the pistol drill is a hexagonal prism rotary interface.

[0012] A further aspect of the solution is that the diameter of the through holes corresponding to the through slots on the top and bottom plates of the square box is equal to the length of the through slots.

[0013] The beneficial effects of this invention are: simple structure, quick installation and clamping of turnbuckles, use of a pistol drill to connect to the rotating interface, and drive the active bevel gear through the pistol drill to quickly rotate the adjusting nut to achieve the effect of loosening or tightening the turnbuckle. The turnbuckle can be quickly adjusted to achieve the effect of tightening the steel wire ropes at both ends of the turnbuckle. When it is necessary to loosen the turnbuckle, it can be quickly adjusted in the opposite direction to a state without stress, reducing labor intensity and improving work efficiency.

[0018] A quick-adjustment wrench for turnbuckles, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wrench includes a square handheld housing 1. The handheld housing, or housing, is small in size and can be operated with one hand. Figure 1 The diagram shows an exploded view of the enclosure, which includes a bottom plate, four side plates, and a top plate. These plates are connected and fixed together by bolts. Bevel gears are mounted on the bottom plate 101 and one side plate 102. The bevel gear on the side plate is called the driving bevel gear 2, and the bevel gear on the bottom plate is called the driven bevel gear 3. The driving bevel gear has a rotating shaft 201, which is rotatably fixed to the side plate 102 via a bearing 4 and a locking nut 5. The rotating shaft 201 is located on the outer side of the side plate. A rotary interface 202 for connection to a pistol drill is provided, either directly or via connection. The driving bevel gear 2 and driven bevel gear 3 mesh at a 90-degree angle within a square housing. The outer end of the toothed portion of the driven bevel gear 3 is an outwardly protruding annular platform 301. An arc-shaped slide rail groove 6 is provided on the base plate 101. The driven bevel gear 3 is rotatably engaged in the arc-shaped slide rail groove 6 via the annular platform 301. The arc-shaped slide rail groove 6 has a groove break on the other side of the square housing opposite the side plate where the driving bevel gear is located. Figure 1As shown, the arc slide rail groove is composed of three arc slide rail grooves. The arc length of each arc slide rail groove is one-tenth to one-sixth of the circumference of the driven bevel gear 3. The three arc slide rail grooves are set at a 120° angle on the annular platform 301. This structure can make room for the slide rail groove break, that is, the slide rail groove break is formed between two slide rail grooves.

[0019] A through slot 302 is provided on the central plane surrounding the toothed portion of the driven bevel gear 3. The through slot 302 is used to accommodate the turnbuckle adjustment rod 801 of the turnbuckle 8. Therefore, the width of the through slot 302 is slightly larger than the thickness of the turnbuckle by 1mm to 2mm. Corresponding to the through slot 302, an openable notch 303 is cut into the toothed portion of the driven bevel gear 3 and the annular platform. The notch 303 is connected to the circular platform by a shaft pin 304. The turnbuckle can pass through the openable notch 303. The through slot 302 is inserted into the box. A through hole 103-1 is provided on the top plate 103 of the square box corresponding to the through slot 302. A through hole 101-1 is provided on the bottom plate 101 of the square box corresponding to the through slot 302. The side plate 104 on the other side is connected to the through holes of the top plate 103 and the bottom plate 101 and is provided with a through vertical long slot 104-1 for inserting the turnbuckle and the turnbuckle adjustment rod. The side plate on the other side is provided with a horizontal slot 104-2 at the position corresponding to the driven bevel gear for opening the notch block 303.

[0020] like Figure 3 As shown, the turnbuckle 8 consists of a turnbuckle adjustment rod 801 with left-hand and right-hand threaded nuts at both ends, and a bolt pull rod into which the nuts are screwed (it is a widely used standard adjustment tool). The thickness of the turnbuckle is different for different models of turnbuckles. In order to cope with different models of turnbuckles, the through slot is changed to different specifications of slot width through a replaceable slot module structure. That is, a notch is set in the central plane around the toothed part of the driven bevel gear 3, a replaceable slot module is set in the notch, a slot is set in the notch, and the slot module is locked in the notch through the slot. Different slot modules have different specifications of through slots 302.

[0021] In order to enable the driven bevel gear 3 to rotate smoothly in the arc slide rail groove, arc grooves are provided at intervals on the upper and lower surfaces of the arc slide rail groove. Roller balls 7 are provided in the arc grooves, and the roller balls rest on the upper and lower planes of the driven bevel gear ring platform. This structure is like a bearing sleeved on the driven bevel gear 3. After adding lubricating oil, the driven bevel gear 3 rotates more smoothly.

[0022] Among them: such as Figure 1 As shown, the arc slide rail groove is composed of a box bottom plate and an arc pressure plate. The arc pressure plate has a "Z" shaped cross section and the upper and lower plates of the "Z" shape are bent at right angles. The arc pressure plate is fixed to the box bottom plate with screws to form the arc slide rail groove.

[0023] To balance effort saving and speed: the speed ratio of the driving bevel gear to the driven bevel gear is 1:1, 2:1 or 3:1, but it is not limited to this and can be set according to needs.

[0024] In the examples: such as Figure 3 As shown, the rotary interface connected to the pistol drill is a hexagonal prism rotary interface. During connection, an external hexagonal sleeve is fitted onto the hexagonal prism rotary interface, and the pistol drill clamps the external hexagonal sleeve to drive the drive bevel gear 2 to rotate.

[0025] In the embodiment: the diameter of the through hole corresponding to the through slot on the top and bottom plates of the square box is equal to the length of the through slot.

[0026] In use, first open the notch block 303, then insert the square box into the turnbuckle through the open notch. Connect the pistol drill to the rotating interface, hold the square box with one hand, and use the other hand to control the pistol drill to quickly rotate the turnbuckle to achieve rapid adjustment. In this embodiment, the turnbuckle quick adjustment wrench has a simple structure and can quickly install and lock the turnbuckle. It uses a pistol drill connected to the rotating interface, and drives the active bevel gear to drive the driven bevel gear to quickly rotate the adjusting nut to achieve the effect of loosening or tightening the turnbuckle. It can quickly adjust the turnbuckle to achieve the effect of tightening the steel wire rope at both ends of the turnbuckle. When it is necessary to loosen the turnbuckle, it can be quickly adjusted in the opposite direction to the unstressed state, reducing labor intensity and improving work efficiency.
