[0001] The invention relates to the technical field of transportation, and more particularly to a steel bar auxiliary transporting device used in a construction site. Background Art

[0002] When workers at a construction site carry steel bars, in order to increase the convenience of carrying, they usually place the steel bars on a cart and carry them by moving the cart.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

The unlocking assembly 26 is used to control the positioning column 215 to disengage from the positioning groove 251. The transmission rod 27 is used to transmit the rotational force of the rotating rod 211 to the clamping mechanism 3.

[0031] Furthermore, the top of the receiving frame 21 is fixedly connected to the frame 1, the bridge frame 22 is fixedly installed on the surface of the rotating rod 211, a rolling groove 231 is opened on the support frame 23, wheels 12 are installed at the four corners of the bottom of the frame 1, and the rolling groove 231 matches the wheel 12. A pedal frame 221 is fixedly installed on the surface of the bridge frame 22, and the receiving frame 21 is fixedly connected to the limiting plate 212 on the side facing the fixed frame 24. One end of the rotating rod 211 is fixedly connected to the extension plate 214, and one end of the positioning column 215 is fixedly connected to the extension plate 214. The rotating rod 211 A first coil spring 213 is also sleeved on one end, and the elastic force of the first coil spring 213 drives the extension plate 214 to fit with the limit plate 212. The fixing frame 24 is fixedly connected to the frame 1. A rotating rod 241 is rotatably installed on the fixing frame 24, and the positioning plate 25 is fixedly installed on the surface of the rotating rod 241. A limit strip 243 is arranged on one side of the fixing frame 24, and the limit strip 243 is fixedly connected to the frame 1. A second coil spring 242 is sleeved on one end of the rotating rod 241, and the elastic force of the second coil spring 242 drives the positioning plate 25 to fit with the limit strip 243.

[0032] Furthermore, the unlocking assembly 26 includes a toggle rod 261 and a central axis 262, both ends of the central axis 262 are fixedly connected to the frame 1, the toggle rod 261 is rotatably installed on the surface of the central axis 262, the bottom end of the toggle rod 261 is fixedly connected to a toggle column 263, the side of the positioning plate 25 away from the limit strip 243 is fixedly connected to an arc plate 253, the toggle column 263 fits with the arc plate 253, the top of the toggle rod 261 is fixedly connected to a pressing handle 264, the toggle rod 261 and the frame 1 are fixedly connected by an elastic metal sheet 265, a guide arc surface 252 is provided on the top of the positioning plate 25, and the guide arc surface 252 matches the positioning column 215, when the staff presses the pressing handle 264 by hand, the elastic metal sheet 265 will be tightened and the elastic force will increase, when the pressing handle 264 is released, the elastic force of the elastic metal sheet 265 will be released and play a role in resetting.

[0033] Furthermore, the transfer rod 27 is rotatably mounted on the frame 1, and a power transmission component 28 is arranged between one end of the transfer rod 27 and the other end of the rotating rod 211. The power transmission component 28 is used to transmit the rotational force of the rotating rod 211 to the transfer rod 27. The other end of the transfer rod 27 is provided with a first bevel gear 271 and a second bevel gear 272. The first bevel gear 271 is fixedly mounted on the other end of the transfer rod 27. Preferably, the power transmission component 28 is a belt drive structure, and the first bevel gear 271 and the second bevel gear 272 cooperate with each other to transmit the rotational force of the transfer rod 27 to the clamping mechanism 3.

[0034] When in use, if the steel bars need to be removed, the staff switches the supporting mechanism 2 to the supporting state. The specific operation is that the staff grabs the handles on the frame 1 with both hands, lifts the frame 1 slightly, and steps on the pedal frame 221 downward with the foot, so that the bridge frame 22 and the supporting frame 23 rotate downward around the axis of the rotating rod 211 as a whole. At the same time, under the traction of the bridge frame 22, the rotating rod 211 rotates synchronously around its own axis, and the rotating rod 211 rotates and drives the positioning column 215 to rotate synchronously around the axis of the rotating rod 211 through the extension plate 214. Under the traction of the rotating rod 211, the first coil spring 213 is tightened and the elastic force is increased. The positioning column 215 first contacts with the guide arc surface 252, and at the positioning column 215 Under the push, the positioning plate 25 rotates synchronously around the axis of the rotating rod 241 in the direction away from the limiting strip 243, and the rotating rod 241 also rotates synchronously around its own axis. Under the pulling of the rotating rod 241, the second coil spring 242 is tightened and the elastic force increases, and then the positioning column 215 enters the positioning groove 251. At this time, the support frame 23 just comes to the bottom of the wheel 12, and the bottom of the wheel 12 enters the rolling groove 231. The positioning column 215 and the positioning groove 251 cooperate with each other to fix the positions of the rotating rod 211, the bridge frame 22 and the support frame 23. The support frame 23 contacts the ground to support the overall structure. At this time, the support mechanism 2 is switched to the supporting state, and the clamping mechanism 3 is automatically switched to the relaxed state;

[0035] If it is necessary to move the steel bars, the staff will switch the support mechanism 2 to the walking state. The specific operation is that the staff grabs the handle on the frame 1, slightly lifts the frame 1 and presses the pressing handle 264 by hand to make the toggle rod 261 rotate around the axis of the central axis 262. The toggle rod 261 rotates and drives the toggle column 263 to rotate synchronously around the axis of the central axis 262. The toggle column 263 squeezes the arc plate 253 and pulls the positioning plate 25 to move synchronously around the axis of the rotating rod 241 in the direction away from the limit strip 243. At this time, the positioning column 215 is disengaged from the positioning groove 251, the elastic force of the first coil spring 213 is released, and the first coil spring 213 is The elastic force drives the rotating rod 211 to rotate around its own axis, and the rotating rod 211 rotates and drives the extension plate 214 and the limit plate 212 to fit together. The rotating rod 211 drives the bridge frame 22 and the support frame 23 to rotate upward as a whole, and the side of the wheel 12 enters the rolling groove 231. The staff releases the pressing handle 264, and the elastic force of the second coil spring 242 is released. The elastic force of the second coil spring 242 drives the rotating rod 241 to rotate around its own axis, so that the positioning plate 25 and the limit strip 243 fit together, and the four wheels 12 support the overall structure. At this time, the supporting mechanism 2 is switched to the walking state, and the clamping mechanism 3 is automatically switched to the clamping state.

[0036] In summary, when it is necessary to unload the steel bars, the staff can step on the pedal frame 221 to switch the support mechanism 2 to the supporting state. The support frame 23 contacts the ground to ensure the stability of the overall structure during the unloading process (when loading steel bars, similarly, the support frame 23 contacts the ground to ensure the stability of the overall structure during the unloading process). When it is necessary to transport the steel bars, the staff can press the pressing handle 264 by hand to switch the support mechanism 2 to the walking state. The support frame 23 leaves the ground, and the wheels 12 contact the ground to facilitate the movement of the overall structure. In addition, since the state switching of the support mechanism 2 and the clamping mechanism 3 is completely bound together, when the staff transports the steel bars, the steel bars must be clamped and positioned by the clamping mechanism 3. If the steel bars are not clamped and positioned by the clamping mechanism 3, the support frame 23 will contact the ground, making the overall structure unable to move, effectively avoiding the situation where the staff does not clamp the steel bars and directly transports them for the sake of saving trouble.

[0037] Example 2, reference Figure 1-Figure 9This embodiment provides a clamping mechanism 3 for clamping and positioning the steel bars. The clamping mechanism 3 includes a mounting frame 31 and a rotating frame 32. The mounting frame 31 is fixedly mounted on the surface of the frame 1. A mounting rod 311 is rotatably mounted on the mounting frame 31. The rotating frame 32 is fixedly mounted on the surface of the mounting rod 311. The second bevel gear 272 is fixedly mounted on one end of the mounting rod 311. The first bevel gear 271 is meshed with the second bevel gear 272. A mounting plate 33 is fixedly mounted on the rotating frame 32. An extrusion assembly 34 is arranged at the bottom of the mounting plate 33. The first bevel gear 271 and the second bevel gear 272 cooperate with each other to transmit the rotational force of the transfer rod 27 to the mounting rod 311. The rotational force of the mounting rod 311 can pull the rotating frame 32, the mounting plate 33 and the extrusion assembly 34 to rotate around the axis of the mounting rod 311 as a whole.

[0038] Furthermore, three extrusion assemblies 34 are provided, and a placement groove 11 for loading steel bars is provided on the top of the frame 1. Three extrusion assemblies 34 are provided corresponding to the placement groove 11. The extrusion assembly 34 includes an upper extrusion plate 341 and a lower extrusion plate 342. The top of the upper extrusion plate 341 is fixedly connected to the bottom of the mounting plate 33. The four corners of the top of the lower extrusion plate 342 are fixedly connected to guide rods 343. The upper extrusion plate 341 is sleeved on the surface of the guide rod 343. A connecting shaft 344 is rotatably installed at the bottom of the upper extrusion plate 341. The surface of the connecting shaft 344 is provided with a first connecting rod 345. The first connecting rod There are multiple evenly arranged 345, and a stabilizing frame 347 is fixedly installed on the top of the lower extrusion plate 342. There are multiple stabilizing frames 347 corresponding to the first connecting rod 345. A second connecting rod 346 is arranged between the first connecting rod 345 and the stabilizing frame 347. One end of the first connecting rod 345 is fixedly installed on the surface of the connecting shaft 344, and the other end of the first connecting rod 345 is hinged to one end of the second connecting rod 346, and the other end of the second connecting rod 346 is hinged to the stabilizing frame 347. A third coil spring 348 is sleeved on the surface of the connecting shaft 344, and the elastic force of the third coil spring 348 drives the lower extrusion plate 342 to move downward.

[0039] When in use, if the steel bar needs to be removed, the staff switches the supporting mechanism 2 to the supporting state. During this process, the rotating rod 211 rotates and drives the transmission rod 27 to rotate synchronously around its own axis through the power transmission member 28. The transmission rod 27 rotates and drives the installation rod 311 to rotate synchronously around its own axis through the first bevel gear 271 and the second bevel gear 272. The installation rod 311 rotates and drives the rotating frame 32, the mounting plate 33 and the extrusion assembly 34 to rotate synchronously around the axis of the installation rod 311 as a whole. The extrusion assembly 34 leaves the top of the placement groove 11. At this time, the clamping mechanism 3 is switched to the relaxed state;

[0040] If the steel bars need to be transported, the staff switches the supporting mechanism 2 to the walking state. During this process, the elastic force of the first coil spring 213 is released and drives the rotating rod 211 to rotate around its own axis. The rotating rod 211 rotates and drives the extrusion assembly 34 to the top of the placement slot 11. The lower extrusion plate 342 moves upward along the axis of the guide rod 343 under the extrusion of the steel bars in the placement slot 11. The lower extrusion plate 342 moves and drives the connecting shaft 344 to rotate synchronously around its own axis through the second connecting rod 346 and the first connecting rod 345. Under the traction of the connecting shaft 344, the third coil spring 348 is tightened and the elastic force increases. The third coil spring 348 applies a downward force to the lower extrusion plate 342, so that the lower extrusion plate 342 presses the steel bars and positions them in the placement slot 11. At this time, the clamping mechanism 3 is switched to the clamping state.

[0041] In summary, when the steel bars need to be unloaded, the clamping mechanism 3 is switched to the relaxed state, and the staff can unload the steel bars in the placement slot 11. When the steel bars need to be transported, the clamping mechanism 3 is switched to the clamping state, and the third coil spring 348 applies a downward force to the lower extrusion plate 342, so that the lower extrusion plate 342 presses the steel bars and positions them in the placement slot 11, effectively preventing the steel bars from bumping and sliding, and ensuring the stability of the steel bars during transportation.

[0042] Preferably, if the steel bar to be transported is too long and the center of gravity of the steel bar is located outside the frame 1, two auxiliary transport devices can be used to transport the two ends of the steel bar respectively, thereby effectively improving the load-bearing range of the steel bar length and weight.

[0043] The working principle of the present invention is as follows: when it is necessary to remove the steel bars in the placement groove 11, the staff switches the supporting mechanism 2 to the supporting state and switches the pressing mechanism 3 to the relaxing state. The specific operation is that the staff grasps the handles on the frame 1 with both hands, slightly lifts the frame 1, and steps down on the pedal frame 221 with his feet, so that the bridge frame 22 and the supporting frame 23 rotate downward around the axis of the rotating rod 211 as a whole. At the same time, under the traction of the bridge frame 22, the rotating rod 211 rotates synchronously around its own axis. The rotating rod 211 rotates and drives the positioning column 215 to rotate synchronously around the axis of the rotating rod 211 through the extension plate 214. Under the traction of the rotating rod 211, the first coil spring 213 is tightened and the elastic force is increased, and the positioning column 215 is First, it contacts with the guiding arc surface 252, and under the push of the positioning column 215, the positioning plate 25 rotates synchronously around the axis of the rotating rod 241 in the direction away from the limiting strip 243, and the rotating rod 241 also rotates synchronously around its own axis. Under the pulling of the rotating rod 241, the second coil spring 242 is tightened and the elastic force increases, and then the positioning column 215 enters the positioning groove 251. At this time, the support frame 23 just comes to the bottom of the wheel 12, and the bottom of the wheel 12 enters the rolling groove 231. The positioning column 215 and the positioning groove 251 cooperate with each other to fix the positions of the rotating rod 211, the bridge frame 22 and the support frame 23. The support frame 23 contacts the ground to support the overall structure, and the support mechanism 2 is switched to the supporting state.

[0044] When the staff steps on the pedal frame 221 to make the rotating rod 211 rotate around its own axis, the rotating rod 211 drives the transmission rod 27 to rotate synchronously around its own axis through the power transmission member 28. The transmission rod 27 rotates and drives the mounting rod 311 to rotate synchronously around its own axis through the first bevel gear 271 and the second bevel gear 272. The mounting rod 311 rotates and drives the rotating frame 32, the mounting plate 33 and the extrusion assembly 34 to rotate synchronously around the axis of the mounting rod 311 as a whole. The extrusion assembly 34 leaves the top of the placement groove 11, and the clamping mechanism 3 is switched to a relaxed state. The staff can remove the steel bars in the placement groove 11.

[0045] When it is necessary to transport the steel bars, the staff switches the supporting mechanism 2 to the walking state and the clamping mechanism 3 to the clamping state. The specific operation is that the staff puts the steel bars into the placement groove 11, grabs the handle on the frame 1, slightly lifts the frame 1 and presses the pressing handle 264 by hand to make the toggle rod 261 rotate around the axis of the central axis 262. The toggle rod 261 rotates and drives the toggle column 263 to rotate synchronously around the axis of the central axis 262. The toggle column 263 squeezes the arc plate 253 and pulls the positioning plate 25 to move synchronously around the axis of the rotating rod 241 in the direction away from the limit strip 243. At this time, the positioning column 215 is disengaged from the positioning groove 251, and the first The elastic force of the coil spring 213 is released, and the elastic force of the first coil spring 213 drives the rotating rod 211 to rotate around its own axis. The rotating rod 211 rotates and drives the extension plate 214 to fit together with the limit plate 212. The rotating rod 211 drives the bridge frame 22 and the support frame 23 to rotate upward as a whole, and the side of the wheel 12 enters the rolling groove 231. The staff releases the pressing handle 264, and the elastic force of the second coil spring 242 is released. The elastic force of the second coil spring 242 drives the rotating rod 241 to rotate around its own axis, so that the positioning plate 25 and the limit strip 243 fit together. At this time, the four wheels 12 support the overall structure, and the support mechanism 2 is switched to the walking state.

[0046] The elastic force of the first coil spring 213 is released and drives the rotating rod 211 to rotate around its own axis. The rotating rod 211 rotates and drives the extrusion assembly 34 to the top of the placement groove 11. The lower extrusion plate 342 moves upward along the axis of the guide rod 343 under the extrusion of the steel bars in the placement groove 11. The lower extrusion plate 342 moves and drives the connecting shaft 344 to rotate synchronously around its own axis through the second connecting rod 346 and the first connecting rod 345. Under the traction of the connecting shaft 344, the third coil spring 348 is tightened and the elastic force increases.
