[0046] Example 1

[0047] The utility model provides a straight thread steel bar auxiliary connection device, referring to Figure 1 The device includes a movable support 1, a universal wheel 2, a driving member 3, a pipe wrench 4, a controller 5 and a torque detection structure 6, wherein:

[0048] The universal wheel 2 is installed at the bottom of the mobile support 1;

[0049] The driving member 3 is mounted on the movable support 1, and the output shaft of the driving member 3 is connected to the pipe wrench 4;

[0050] The controller 5 is electrically connected to the driving member 3 and the torque detection structure 6, and can control the start and stop of the driving member 3;

[0051] The torque detection structure 6 is used to detect the working torque of the driving member 3 .

[0052] The device is used as follows: the operator first puts the straight thread sleeve onto the head of a steel wire, and then inserts the other steel wire head into the straight thread sleeve; then, one of the steel bars is fixed, and the pipe wrench 4 is clamped around the other steel bar; then, the device is started, the driving member 3 runs and drives the pipe wrench 4 to rotate, thereby driving the steel bar clamped by the pipe wrench 4 to rotate; during the operation of the driving member 3, the torque detection structure 6 detects the working torque of the driving member 3 in real time, and when the working torque of the driving member 3 reaches the torque value required by the specification, the driving member 3 stops running.

[0053] As described above, the straight threaded steel bar auxiliary connection device provided in this embodiment achieves the technical effect of automatically connecting straight threaded steel bars, improving the connection efficiency of straight threaded steel bars and reducing manpower. In addition, the provision of the torque detection structure 6 ensures the stability and consistency of each straight threaded steel bar connection, thereby improving construction quality.

[0054] In this embodiment, the driving member 3 is specifically a motor and can be linked to the torque detection structure 6. When the torque detection structure 6 detects that the working torque of the driving member 3 reaches the required torque value, the driving member 3 automatically stops running.

[0055] Reference Figure 1 and Figure 2 The device further comprises a lifting structure 9, which comprises a bracket 91 and a hook 92. The upper end of the hook 92 is connected to the bracket 91, and the lower end of the hook 92 is used to hook the steel bar. Figure 2 As shown, the lifting structure 9 is used to lift the steel bars during the construction process so that the driving member 3 can drive the steel bars to rotate through the pipe wrench 4.

[0056] Optionally, the number of the hooks 92 can be one or more. By providing multiple hooks 92, multiple steel bars can be lifted at one time, and a streamlined connection operation of multiple steel bars can be achieved, further improving the construction speed.

[0057] On the basis of the above structure, the lifting structure 9 further includes a sleeve 93, which is fixed to the upper end of the hook 92;

[0058] The bracket 91 includes a top connecting rod and support rods fixed on both sides of the top connecting rod, and the sleeve 93 is slidably sleeved on the top connecting rod.

[0059] Specifically, the support rod has an inverted V-shaped structure, and the two ends of the top connecting rod are respectively welded to the top of the two support rods; the number of sleeves 93 and hooks 92 is the same and corresponds one to one, and the sleeves 93 are welded to the top of the corresponding hooks 92; the sleeves 93 are slidably mounted on the top connecting rod, so that the position of the hook 92 can be easily adjusted, which is convenient for the operator to operate.

[0060] Optionally, a set screw is threaded onto the wall of the sleeve 93 . After the position of the hook 92 is adjusted, the sleeve 93 can be fixed by the set screw to prevent the hook 92 from shifting.

[0061] Reference Figure 3 The movable support 1 includes a lower support plate, an upper support plate, and several struts connecting the lower and upper support plates. The movable support 1 can be integrally formed by welding. Multiple universal wheels 2 are fixed to the bottom of the lower support plate. A drive member 3 is mounted on the upper end surface of the lower support plate. A controller 5 is mounted on the upper end surface of the upper support plate.

[0062] Furthermore, the controller 5 is equipped with a display screen 51 and / or several control buttons 52. The display screen 51 displays the torque value in real time for easy viewing by the operator. The control buttons 52 include a main on / off button, a forward rotation button, a stop rotation button, and a reverse rotation button. These features make the device more user-friendly and quick to operate.

[0063] Furthermore, the device also includes an alarm structure, which is electrically connected to the controller 5 and is used to issue an alarm when the working torque reaches a set value. The alarm can be a flashing light or a voice prompt, which is not limited here.

[0064] Continue to refer to Figure 3 The device also includes a connecting rod 7 and a coupling 8, the coupling 8 is connected between the output shaft and one end of the connecting rod 7, and the other end of the connecting rod 7 is connected to the pipe wrench 4.

[0065] Optionally, the coupling 8 is a universal coupling (such as Figure 4 as shown), or a helical spring coupling (as Figure 5 The above couplings are all prior art and their structures are not described in detail here.

[0066] Continue to refer to Figure 3 In this embodiment, the coupling 8 is a universal coupling. The universal coupling has good angular adaptability and can transmit power and torque within a certain angular deviation range of the shaft, meeting the transmission requirements of different angles and directions.

[0067] Furthermore, the torque detection structure 6 includes a torque sensor 61, which is mounted on the movable support 1 and connected between the output shaft of the driver 3 and the connecting rod 7. Specifically, the two ends of the torque sensor 61 are connected to the driver 3 and the connecting rod 7 respectively via a coupling 8. The torque sensor 61 can directly detect the operating torque value of the driver 3 during its operation.

[0068] Reference Figure 6 and Figure 7 As an optional embodiment, the connecting rod 7 includes a first rod body 71 and a second rod body 72, which are nested inside and outside and slidably connected along the axial direction of the connecting rod 7. Specifically, a sliding groove with a cross-shaped cross section is provided in the first rod body 71; one end of the second rod body 72 is slidably inserted into the sliding groove, and the cross-section of the end of the second rod body 72 inserted into the sliding groove is also cross-shaped to match the shape of the sliding groove.

[0069] Since the first rod body 71 and the second rod body 72 can be slidably connected along the axial direction of the connecting rod 7, when the pipe wrench 4 rotates the steel bar, the pipe wrench 4 can adaptively move with the steel bar, making the construction process smoother.

[0070] Example 2

[0071] The straight threaded steel bar auxiliary connection device provided in this embodiment is different from that in the first embodiment in that the torque detection structure 6 and the coupling 8 have different structures.

[0072] In this embodiment, the coupling 8 is a helical spring coupling or a permanent magnet coupling. With the above coupling, the output shaft of the driving member 3 and the connecting rod 7 no longer rotate synchronously after the torques reach a consistent value.

[0073] Reference Figure 8 In this embodiment, the torque detection structure 6 includes a first sensing member 62 and a first speed sensor 63. The first sensing member 62 is fixed to the circumference of the connecting rod 7. The first speed sensor 63 is installed on the movable support 1 with its monitoring end facing the first sensing member 62.

[0074] And / or, the torque detection structure 6 includes a second sensing element and a second speed sensor, the second sensing element is fixed on the circumference of the output shaft, and the second speed sensor is installed on the movable support 1 with its monitoring end facing the second sensing element.

[0075] In one embodiment, the torque detection structure 6 only includes the first sensing element 62 and the first speed sensor 63. Figure 8 As shown, when the first rotation speed sensor 63 detects that the connecting rod 7 rotates slowly or even stops, it means that the working torque of the driving member 3 reaches the torque value required by the specification.

[0076] In another embodiment, the torque detection structure 6 includes a first sensing element 62, a first speed sensor 63, a second sensing element, and a second speed sensor. The first speed sensor 63 and the second speed sensor can respectively detect the speeds of the connecting rod 7 and the output shaft of the driving element 3, and the corresponding torque value can be calculated based on the speed difference between the two.

[0077] Based on the above structure, the first induction member 62 includes a shaft sleeve and an induction sheet fixed on the outer circumference of the shaft sleeve, and the number of the induction sheet can be one or more. The shaft sleeve is fixed on the connecting rod 7 and fixed by a set screw.

[0078] In addition, in the embodiment where the coupling 8 is a coil spring coupling, a strain sensor may be used to detect the strain generated by the spring being deformed under force, and the corresponding torque value may be calculated.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
