Description

Technical Field

[0001] This utility model belongs to the field of rebar sleeve installation, specifically, it relates to a digital display, multi-size rebar sleeve installation device. Background Technology

[0002] A rebar sleeve (also known as a rebar connector or straight thread sleeve) is a mechanical connector mainly used for the reliable connection of rebars in reinforced concrete structures.

[0003] Our company has invented a rebar sleeve installation device (publication number: CN214641625U), characterized in that it includes: a main frame, the end of the main frame is a duckbill structure, a rotating rod is provided at the center of the main frame, the rotating rod passes through the end of the main frame and is provided with an active helical tooth, and a driven helical tooth is provided at the duckbill structure of the main frame.

[0004] In actual use, it was found that when tightening relatively thin rebar sleeves using two sets of symmetrical rotating wheels with a positive center, it can achieve the required speed and prevent slippage. However, when tightening thick rebar sleeves (thick rebar sleeves refer to those with the device open to about four-fifths of the meshing angle), slippage occurs, and the rebar sleeve cannot be properly gripped. Furthermore, due to the heavy weight of the wrench itself and the large torque it can provide, coupled with the wide range of techniques used by technicians, over-tightening (such as stripping) is easily caused when technicians use this device to tighten rebar sleeves, resulting in a significant reduction in the fixing strength of the rebar.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the aforementioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

The limiting axis is rotatably connected between the symmetrical limiting plates. The eccentric clamping column is sleeved on the wall of each limiting axis.

[0014] In a preferred embodiment of this utility model, the main gear column is composed of a round shaft and gears. The upper bevel gear is fixedly connected to the round shaft of the main gear column and can mesh with the bevel gear on the front wall of the main shaft. The connecting shaft is cylindrical, and the upper and lower ends of the connecting shaft can be inserted into the corresponding limiting plate wall.

The usage and principle of the tensioning module are consistent with the prior art. This is the prior art, so it will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping structure is set between symmetrical limiting plates 24 for clamping the rebar sleeve. The clamping structure includes: limiting shaft 31, eccentric clamping column 32, slot 33 and driven wheel 34. The limiting shaft 31 is rotatably connected between the symmetrical limiting plates 24. The eccentric clamping column 32 is sleeved on the wall surface of each limiting shaft 31. The slot 33 is opened through the top of the eccentric clamping column 32. The driven wheel 34 is fixedly connected to the wall surface of the limiting shaft 31. The symmetrical eccentric clamping column 32 can clamp the rebar sleeve.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the limiting shaft 31 is cylindrical and symmetrically arranged between the upper and lower limiting plates 24 on each side. The upper and lower ends of the limiting shaft 31 can pass through the limiting plates 24. The wall surface of each limiting shaft 31 is provided with the same eccentric clamping column 32 and driven wheel 34. The eccentric clamping column 32 is cylindrical, and each eccentric clamping column 32 has a spiral anti-slip texture on its arc surface. The slot 33 is opened at the eccentric top of the eccentric clamping column 32. The wall surface of each limiting shaft 31 is provided with the same eccentric clamping column 32 symmetrically arranged. The driven wheel 34 is located between the symmetrical eccentric clamping columns 32 and is gear-shaped. The clamping structure also includes: main gear column 22, upper gear column 23, and driven wheel 34. The system comprises a bevel gear 23, a connecting shaft 25, a first moving gear 26, a second moving gear 27, a third moving gear 28, a fourth moving gear 29, and a fifth moving gear 30. The main gear column 22 is rotatably connected between symmetrical rectangular plates on the front wall of the main box 20. The upper bevel gear 23 is fixedly connected to the wall of the main gear column 22. The connecting shaft 25 is rotatably connected between symmetrical limiting plates 24. The first moving gear 26, the second moving gear 27, the third moving gear 28, the fourth moving gear 29, and the fifth moving gear 30 are also rotatably connected between symmetrical limiting plates 24 on each side. The moving gear 30 is also rotatably connected between the symmetrical limiting plates 24 on each side. The main gear column 22 is composed of a round shaft and a gear. The upper bevel gear 23 is fixedly connected to the round shaft of the main gear column 22. The upper bevel gear 23 can mesh with the bevel gear on the front wall of the main shaft 21. The connecting shaft 25 is cylindrical. The upper and lower ends of the connecting shaft 25 can be inserted into the corresponding wall of the limiting plate 24. A disc is fixedly connected to the end of each connecting shaft 25. The same connecting shaft 25 is provided on the wall of each first moving gear 26, second moving gear 27, third moving gear 28, fourth moving gear 29 and fifth moving gear 30. The main gear column 22 can mesh with the symmetrical first moving gear 26 in front. The first moving gear 26 on each side can mesh with the second moving gear 27 in front, the second moving gear 27 on each side can mesh with the third moving gear 28 in front, the third moving gear 28 on each side can mesh with the fourth moving gear 29 in front, the fourth moving gear 29 on each side can mesh with the driven wheel 34 in the front side, the driven wheel 34 in the rear can mesh with the fifth moving gear 30 in front, and the fifth moving gear 30 on each side can mesh with the driven wheel 34 in the frontmost position. The top of the main box 20 is provided with a through mounting groove 35, and a torque meter 36 is fixedly connected in the mounting groove 35. The front and rear walls of the torque meter 36 are respectively rotatably connected to torque columns 37.

[0033] In practical use, by pulling the handle of the tensioning module, the spacing of the symmetrical limiting plates 24 is controlled to match the size of the steel sleeve to be tightened. The outer wall of the steel sleeve is brought into contact with the outer walls of all the eccentric clamping columns 32. After the spacing of the symmetrical limiting plates 24 is adjusted, the hollow cylinder can be driven to rotate using a wrench or electric drill. When the hollow cylinder is driven to rotate, it will drive the corresponding torque column 37 to rotate. The torque of the torque column 37 during rotation is displayed on the torque meter 36, and it will also drive another torque column 37 to rotate. The rotation of the other torque column 37 will drive the main shaft 21 to rotate. As the main shaft 21 rotates, it will drive the bevel gear at its front end to rotate. Simultaneously, as the bevel gear on the wall of the main shaft 21 rotates, it will drive the upper bevel gear 23 and... The main gear 22 rotates between symmetrical rectangular plates. When the main gear 22 rotates, it drives two first moving gears 26 to rotate between upper and lower symmetrical limiting plates 24. The first moving gear 26 can drive the second moving gear 27 to rotate, the second moving gear 27 can drive the third moving gear 28 to rotate, the third moving gear 28 can drive the fourth moving gear 29 to rotate, the fourth moving gear 29 can drive the rear driven wheel 34 to rotate, the rear driven wheel 34 can drive the fifth moving gear 30 to rotate, and the fifth moving gear 30 can drive the front driven wheel 34 to rotate. As the driven wheel 34 rotates, it can drive each corresponding limiting shaft 31 to rotate synchronously. As the limiting shaft 31 rotates, it can drive the eccentric clamping column 32 to rotate and drive the steel bar sleeve to rotate, thereby realizing the twisting of the steel bar sleeve.

[0034] In summary, by setting up a clamping structure, the rotation of each eccentric clamping column 32 can be controlled, thereby driving the rotation of the rebar sleeve. This enables a stable and non-slip rotation effect when clamping the thick rebar sleeve (the thick rebar sleeve refers to the sleeve after the device opens to about four-fifths of its engagement angle).

[0035] like Figure 5 As shown, the mounting slot 35 can be adapted to the size of the torque gauge 36, the mounting slot 35 can communicate with the cavity of the main box 20, the front torque column 37 can be fixedly connected to the rear end of the main shaft 21, and the rear torque column 37 can be fixedly connected to the hollow cylinder inside the cavity of the main box 20.

[0036] In practical use, when the hollow cylinder is driven to rotate, it will drive the corresponding torque column 37 to rotate. The torque when the torque column 37 rotates will be displayed through the torque meter 36, and it will also drive another torque column 37 to rotate.

[0037] In summary, by setting the torque meter 36, the real-time torque of the spindle 21 can be displayed, thereby effectively preventing over-tightening due to blindly tightening the rebar sleeve and affecting the fixing strength of the rebar.

[0038] Working principle: By pulling the handle of the tensioning module, the spacing of the symmetrical limiting plates 24 is controlled to match the size of the steel rebar sleeve to be tightened. The outer wall of the steel rebar sleeve contacts the outer wall of all the eccentric clamping columns 32. After the spacing of the symmetrical limiting plates 24 is adjusted, the hollow cylinder can be driven to rotate using a wrench or electric drill. When the hollow cylinder is driven to rotate, it drives the corresponding torque column 37 to rotate. The torque of the torque column 37 during rotation is displayed on the torque meter 36. It also drives another torque column 37 to rotate, which in turn drives the main shaft 21 to rotate. The rotation of the main shaft 21 drives the bevel gear at its front end to rotate. As the bevel gear on the wall of the main shaft 21 rotates, it simultaneously drives the upper bevel gear 23 and the main gear column 22 to rotate between the symmetrical rectangular plates. When the main gear column 22 rotates, it drives the two first moving gears 26 to rotate between the upper and lower symmetrical limiting plates 24. The first moving gear 26 can drive the second moving gear 27 to rotate, the second moving gear 27 can drive the third moving gear 28 to rotate, the third moving gear 28 can drive the fourth moving gear 29 to rotate, the fourth moving gear 29 can drive the rear driven wheel 34 to rotate, the rear driven wheel 34 can drive the fifth moving gear 30 to rotate, and the fifth moving gear 30 can drive the front driven wheel 34 to rotate. As the driven wheel 34 rotates, it can drive each corresponding limiting shaft 31 to rotate synchronously. As the limiting shaft 31 rotates, it can drive the eccentric clamping column 32 to rotate and drive the rebar sleeve to rotate, thereby realizing the screwing of the rebar sleeve. After the rebar sleeve is installed, the wall of the eccentric clamping column 32 and the rebar sleeve can be separated.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
