Description

Technical Field

[0001] This utility model relates to the field of steel bar technology, and in particular to a device for quickly inserting steel bars. Background Technology

[0002] Sand barriers, also known as mechanical sand barriers, refer to various sizes of barriers set up on the surface of shifting sand using biological or non-biological materials. Their purpose is to control the direction, speed, and structure of wind and sand movement, change wind erosion, prevent wind and sand, and alter the effects of wind and micro-topography. Sand barriers are considered a prerequisite and guarantee for biological sand control. Currently, polyamide sand barriers are widely used in the sand control and afforestation process of the Three-North Shelterbelt Project. Polyamide sand barriers mainly utilize steel bars as supports and polyamide as a sand-blocking material.

[0003] In the existing technology, since the inner diameter of the device cannot be adjusted, different specifications of pipes or additional adjustments are required during installation, which increases the complexity and time cost of installation. Furthermore, the length of the device cannot be adjusted according to the length of the steel bar on the ground, resulting in uncontrollable insertion depth. This leads to unstable installation of the steel bar, affecting the stability and protective effect of the sand barrier. Therefore, a device for quickly inserting steel bars is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the technical problems in existing technologies, such as the need to use pipes of different specifications or make additional adjustments during installation, which increases the complexity and time cost of installation, and the inability to adjust the length of the device according to the length of the rebar on the ground, resulting in uncontrollable insertion depth and unstable installation of the rebar, this application provides a device for quickly inserting rebar.

[0005] This utility model proposes a device for quickly inserting reinforcing bars, which includes a reinforcing bar body and a moving tube. The outer surface of the moving tube is provided with an adjustment mechanism, which includes a fixing block. The movement of the fixing block fixes the moving tube.

[0006] The outer surface of the movable tube is provided with a fixing mechanism, which includes a fixing plate. The movement of the fixing plate fixes the steel bar body.

[0007] Preferably, the adjustment mechanism further includes a support tube, the inner wall of the groove of the support tube is slidably inserted into the outer surface of the moving tube, the top end of the moving tube is rotatably connected to a handle through a bearing, a motor is fixedly installed on the inner wall of the handle, and the output shaft of the motor is fixedly installed on the upper surface of the moving tube.

[0008] Through the above technical solution, the support tube and the moving tube are slidably connected, which fixes the steel bar without affecting its movement. The support tube moves inside the moving tube, which allows the overall length of the device to be adjusted according to the length of the steel bar body on the ground. The moving tube and the handle are rotatably connected through a bearing, which fixes the steel bar without affecting its rotation. The handle is fixedly installed to the motor, which drives the moving tube to rotate, thereby rotating the steel bar body fixed by the fixing mechanism, so that the steel bar body can be inserted into the sand more smoothly.

[0009] Preferably, a sleeve is fixedly installed on the outer surface of the support tube, and a star-head screw is threadedly connected to the inner wall of the groove of the sleeve. One end of the star-head screw is rotatably connected to the outer surface of the fixing block, and the fixing block is slidably inserted into the inner wall of the sleeve.

[0010] The above technical solution involves fixing the support tube and the sleeve, and connecting the sleeve with a star-head screw. The operator can rotate the star-head screw to move it within the sleeve. The star-head screw is rotatably connected to the fixing block, ensuring that the rotation of the star-head screw does not affect the fixing block while fixing it, thus allowing it to move synchronously. The fixing block is slidably inserted into the sleeve to limit its movement, allowing it to move only. After the fixing block comes into contact with the moving tube, the moved tube can be fixed.

[0011] Preferably, the fixing mechanism further includes rotating tubes, the inner walls of the two rotating tubes being threadedly connected to the top surface of the moving tube and the bottom surface of the supporting tube, respectively. The surface of the driving disk installed on the inner wall of the rotating tube is rotatably connected to the inner wall of the groove of the moving tube and the inner wall of the groove of the supporting tube, respectively. The thickness of the inner wall of the groove of the moving tube and the thickness of the inner wall of the groove of the supporting tube are both greater than the thickness of the driving disk installed on the inner wall of the rotating tube.

[0012] With the above technical solution, the rotating tube is threadedly connected to the moving tube and the support tube respectively. Rotating any one of the rotating tubes can make it rotate and rise on its outer surface. However, since the rotating tube is rotatably connected to the moving tube and the support tube respectively, it can be fixed without affecting its rotation. The width of the arc-shaped groove opened around the moving tube and the support tube is greater than the thickness of the drive plate installed on the inner wall of the rotating tube, allowing it to have a space for up and down movement. The threaded connection can maintain the current state by tightening the thread after rotation and prevent the rotating tube from continuing to rotate.

[0013] Preferably, the drive disc mounted on the inner wall of the rotating tube is further provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is slidably connected to the pin surface mounted on the top of the fixed plate.

[0014] Through the above technical solution, multiple arc-shaped grooves are also opened on the surface of the drive disc installed on the inner wall of the rotating tube. When the rotating tube rotates, the arc-shaped grooves are slidably connected to the pin surface installed on the top of the fixed plate, allowing it to slide in the arc-shaped grooves, thereby fixing the steel bars of different diameters.

[0015] Preferably, a circular plate is fixedly installed on the inner wall of both the moving tube and the inner wall of the supporting tube, and a limiting groove is formed on the top surface of the circular plate.

[0016] With the above technical solution, both the moving tube and the support tube are fixedly installed on the circular plate. Multiple limiting grooves are opened on the circular plate to limit the sliding connection of the fixed plate and prevent it from sliding excessively or unevenly.

[0017] Preferably, the inner wall of the limiting groove is slidably connected to the surface of the pin shaft installed at the bottom of the fixing plate, and the outer surface of one fixing plate is slidably inserted into the inner wall of the groove of the other fixing plate.

[0018] Through the above technical solution, the limiting groove is slidably connected to the pin surface installed at the bottom of the fixed plate, and one fixed plate is slidably inserted into another fixed plate, which fixes it without affecting its movement, so as to ensure the stability of the movement of the fixed plate.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting an adjustment mechanism, the moving tube is fixed, and the support tube moves inside the moving tube. This allows the overall length of the device to be adjusted according to the length of the steel bar body on the ground. The motor drives the moving tube to rotate, which in turn drives the steel bar body fixed by the fixing mechanism to rotate, allowing the steel bar body to be inserted into the sand more smoothly. The sleeve is threadedly connected to the star-head screw. The operator can rotate the star-head screw to move it inside the sleeve. The star-head screw is rotatably connected to the fixing block, which moves it synchronously. The fixing block is slidably inserted into the sleeve to limit its movement, thus fixing the moving tube after it has moved. This solves the technical problem in the existing technology where the length of the device cannot be adjusted according to the length of the steel bar on the ground, resulting in uncontrollable insertion depth, unstable installation of the steel bar, and affecting the stability and protective effect of the sand barrier.

[0021] 2. By setting up a fixing mechanism, the steel bar body is fixed. Multiple arc-shaped grooves are opened on the rotating tube. When the rotating tube rotates, the arc-shaped grooves slide in the fixing plate due to their sliding connection, thus fixing steel bars of different diameters. Multiple limiting grooves are opened on the circular plate to limit the fixed plate that slides with it, preventing excessive or uneven sliding. One fixed plate slides into another fixed plate, fixing it without affecting its movement, so as to ensure the stability of the fixed plate movement. This solves the technical problem in the prior art that the inner diameter of the device cannot be adjusted, requiring the use of different specifications of pipes or additional adjustment work during installation, which increases the complexity and time cost of installation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1-8 A device for quickly inserting steel bars includes a steel bar body 1 and a moving tube 11. An adjustment mechanism is provided on the outer surface of the moving tube 11. The adjustment mechanism includes a fixing block 32. The movement of the fixing block 32 fixes the moving tube 11.

[0033] To facilitate adjustment of the overall length of the device according to the length of the steel bar body 1 on the ground, the adjustment mechanism also includes a support tube 2. The inner wall of the groove of the support tube 2 is slidably inserted into the outer surface of the moving tube 11. The top end of the moving tube 11 is rotatably connected to a handle 21 via a bearing. A motor 22 is fixedly installed on the inner wall of the handle 21. The output shaft of the motor 22 is fixedly installed on the upper surface of the moving tube 11. The support tube 2 is slidably inserted into the moving tube 11, fixing it without affecting its movement. The support tube 2 moves within the moving tube 11, facilitating adjustment of the overall length of the device according to the length of the steel bar body 1 on the ground. The moving tube 11 and the handle 21 are rotatably connected via a bearing, fixing it without affecting its rotation. The handle 21 is fixedly installed to the motor 22, fixing it in place. The motor 22 is fixedly installed to the moving tube 11, driving the moving tube 11 to rotate, thereby rotating the steel bar body 1 fixed by the fixing mechanism, allowing the steel bar body 1 to be inserted into the sand more smoothly.

[0034] To fix the moved tube 11, a sleeve 3 is fixedly installed on the outer surface of the support tube 2. A star-head screw 31 is threadedly connected to the inner wall of the groove of the sleeve 3. One end of the star-head screw 31 is rotatably connected to the outer surface of the fixing block 32. The fixing block 32 is slidably inserted into the inner wall of the sleeve 3. The support tube 2 and the sleeve 3 are fixedly installed and fixed. The sleeve 3 is threadedly connected to the star-head screw 31. The operator can rotate the star-head screw 31 to move it inside the sleeve 3. The star-head screw 31 is rotatably connected to the fixing block 32. While fixing it, the rotation of the star-head screw 31 does not affect the fixing block 32, so that it can move synchronously. The fixing block 32 is slidably inserted into the sleeve 3 to limit it, so that it can only move. After it comes into contact with the moved tube 11, the moved tube 11 can be fixed.

[0035] By setting an adjustment mechanism, the moving tube 11 is fixed, and the support tube 2 moves inside the moving tube 11, so that the overall length of the device can be adjusted according to the length of the steel bar body 1 on the ground. The motor 22 drives the moving tube 11 to rotate, so as to drive the steel bar body 1 fixed by the fixing mechanism to rotate, so that the steel bar body 1 can be inserted into the sand more smoothly. The sleeve 3 is threadedly connected to the star head screw 31. The operator can rotate the star head screw 31 to move it inside the sleeve 3. The star head screw 31 is fixedly installed with the fixing block 32, which drives it to move synchronously. The fixing block 32 is slidably inserted into the sleeve 3 to limit it, so that it can only move, thereby fixing the moving tube 11 after it has moved. This solves the technical problem in the prior art that the length of the device cannot be adjusted according to the length of the steel bar on the ground, resulting in the inability to control the insertion depth, which leads to the unstable installation of the steel bar and affects the stability and protective effect of the sand barrier.

[0036] In order to fix the steel bar body 1, a fixing mechanism is provided on the outer surface of the movable tube 11. The fixing mechanism includes a fixing plate 51, and the movement of the fixing plate 51 fixes the steel bar body 1.

[0037] To prevent the rotating tube 4 from continuing to rotate, the fixing mechanism also includes a rotating tube 4. The inner walls of the two rotating tubes 4 are threadedly connected to the top surface of the moving tube 11 and the bottom surface of the support tube 2, respectively. The surface of the drive disk installed on the inner wall of the rotating tube 4 is rotatably connected to the inner wall of the groove of the moving tube 11 and the inner wall of the groove of the support tube 2, respectively. The thickness of the inner wall of the groove of the moving tube 11 and the inner wall of the groove of the support tube 2 are both greater than the thickness of the drive disk installed on the inner wall of the rotating tube 4. The rotating tube 4 is threadedly connected to the moving tube 11 and the support tube 2, respectively. Rotating either of the rotating tubes 4 can make it rotate and rise on its outer surface. However, since the rotating tube 4 is rotatably connected to the moving tube 11 and the support tube 2, it is fixed without affecting its rotation. The width of the arc-shaped groove opened around the moving tube 11 and the support tube 2 is greater than the thickness of the drive disk installed on the inner wall of the rotating tube 4, allowing it to have a space for vertical movement. The threaded connection can maintain the current state by tightening the threads after rotation, preventing the rotating tube 4 from continuing to rotate.

[0038] In order to fix the steel bars 1 of different diameters, the drive disc installed on the inner wall of the rotating tube 4 is also provided with an arc groove 5. The inner wall of the groove of the arc groove 5 is slidably connected to the pin surface installed on the top of the fixing plate 51. By opening multiple arc grooves 5 on the rotating tube 4, when the rotating tube 4 rotates, it slides in the arc groove 5 because the arc groove 5 is slidably connected to the fixing plate 51, thereby fixing the steel bars 1 of different diameters.

[0039] To prevent the fixed plate 51 from sliding excessively or unevenly, a circular plate 6 is fixedly installed on the inner wall of the moving tube 11 and the inner wall of the supporting tube 2. A limiting groove 61 is opened on the top surface of the circular plate 6. The moving tube 11 and the supporting tube 2 are fixedly installed on the circular plate 6 to fix it. By opening multiple limiting grooves 61 on the circular plate 6, the fixed plate 51 that is slidably connected to it can be limited to prevent it from sliding excessively or unevenly.

[0040] To ensure the stability of the movement of the fixed plate 51, the inner wall of the limiting groove 61 is slidably connected to the surface of the pin installed at the bottom of the fixed plate 51, and the outer surface of one fixed plate 51 is slidably inserted into the inner wall of the groove of another fixed plate 51. Through the slidable connection between the limiting groove 61 and the surface of the pin installed at the bottom of the fixed plate 51, one fixed plate 51 is slidably inserted into another fixed plate 51, which fixes it without affecting its movement, so as to ensure the stability of the movement of the fixed plate 51.

[0041] By setting a fixing mechanism, the steel bar body 1 is fixed. Multiple arc-shaped grooves 5 are opened on the rotating tube 4. When the rotating tube 4 rotates, the arc-shaped grooves 5 are slidably connected to the fixing plate 51, allowing it to slide within the arc-shaped grooves 5, thus fixing steel bar bodies 1 of different diameters. Multiple limiting grooves 61 are opened on the circular plate 6, which can limit the fixed plate 51 that is slidably connected to it, preventing it from sliding excessively or unevenly. One fixing plate 51 is slidably inserted into another fixing plate 51, fixing it without affecting its movement, so as to ensure the stability of the movement of the fixing plate 51. This solves the technical problem in the prior art that, because the inner diameter of the device cannot be adjusted, different specifications of pipes or additional adjustment work are required during installation, which increases the complexity and time cost of installation.

[0042] Working principle: When it is necessary to adjust the length of the steel bar body 1 on the ground, the worker holds the moving tube 11 and moves it inside the support tube 2. When it moves to the required length, the star head screw 31 threaded on the sleeve 3 is rotated, which drives the fixing block 32 fixedly installed thereto to move inside the sliding sleeve 3. After it comes into contact with the moving tube 11, the moving tube 11 can be fixed.

[0043] When it is necessary to fix the steel bar body 1, the worker places the steel bar body 1 inside the support pipe 2 and the moving pipe 11, so that one end of the steel bar body 1 contacts the inner top wall of the moving pipe 11. After placement, the rotating pipe 4 rotatably connected to the moving pipe 11 is rotated. The width of the arc-shaped groove opened around the moving pipe 11 and the support pipe 2 is greater than the thickness of the drive plate installed on the inner wall of the rotating pipe 4, allowing it to have a space for vertical movement. The threaded connection between the moving pipe 11 and the rotating pipe 4 can be tightened by the thread after rotation to maintain the current state and prevent the rotating pipe 4 from continuing to rotate. When the rotating pipe 4 rotates, the arc-shaped groove 5 opened on it drives the fixed plate 51 slidably connected to it to move in the limiting groove 61 opened on the circular plate 6. The sliding insertion between the fixed plates 51 can ensure the stability of the movement of the fixed plate 51. After fixing one end of the steel bar body 1 inside the moving pipe 11, the rotating pipe 4 on the support pipe 2 is rotated to fix the steel bar body 1 inside.

[0044] After the steel bar body 1 is fixed, when it is necessary to insert the steel bar body 1 into the sand, the motor 22 in the handle 21 is started to drive the moving tube 11 to rotate, which drives the support tube 2 that is slidably inserted into the moving tube 11 to rotate, thereby driving the steel bar body 1 that is fixedly installed inside to rotate, so that it can be quickly inserted into the sand.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
