In the construction industry, steel platform trucks are an important production tool, primarily for the production and transportation of PC components. Specifically, the steel platform truck needs to be in contact fit with steel rail wheels on the assembly line to realize transportation transfer of the PC components on the assembly line. However, due to the long-time contact with the steel rail wheel, the connection position of the lower wing plate and the rib plate of the steel platform truck is easy to be warped upwards, and the service life of the steel platform truck and the production quality of the PC component are seriously affected.

At present, a straightening mode commonly used in the prior art is manual straightening, namely, a worker applies a corresponding tool to manually straighten the deformed part of the lower wing plate of the steel platform car. However, the main beams on the two sides of the steel platform car are made of Q235B, namely carbon steel, the yield strength of the steel platform car is 235MPa, and the thickness of the middle part of the wing plate is 14 mm. Therefore, during straightening, a large straightening force is needed, and the expected effect cannot be achieved when straightening is directly performed manually, so that the straightening part needs to be heated in advance, then manual straightening is performed, and finally appearance restoration is performed, so that the whole straightening process can be completed.

The straightening mode has quite complex procedures, low straightening efficiency and high working labor intensity. Based on the principle, the inventor notices that the smaller straightening force can be amplified by utilizing the lever principle, so that the straightening force requirement of the lower wing plate of the steel platform car can be met, and the straightening of the lower wing plate of the steel platform car can be realized more simply and conveniently.

Based on the above consideration, in order to solve the problems of complex process, low straightening efficiency and high working strength of the straightening process of the lower wing plate of the steel platform car in the prior art, the inventor designs a straightening device through intensive research, wherein the driving force applied by the first driving mechanism is amplified by the first straightening arm and is converted into the straightening force for the lower wing plate of the steel platform car, so that the lower wing plate of the steel platform car is straightened.

FIGS. 1 and 2 are schematic views each showing the overall structure of a straightening apparatus in an embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to fig. 1 and 2, an embodiment of the invention provides a straightening apparatus 100, which comprises a fixed bracket 10 and a first straightening device 20 arranged on the fixed bracket 10, wherein the first straightening device 20 is used for providing a downward straightening force for a lower wing plate 201 of a steel platform vehicle. The first straightening device 20 includes a first driving mechanism 21 and a first straightening mechanism 22, the first straightening mechanism 22 includes a first straightening arm 221 and a first supporting seat 222, one end of the first straightening arm 221 along the longitudinal direction thereof is rotatably connected with the first supporting seat 222, and the other end is matched with the first driving mechanism 21 to rotate around the first supporting seat 222 under the driving of the first driving mechanism 21. Further, the steel deck lower wing plate 201 is located on the rotation path of the first straightening arm 221, and a downward straightening force can be applied to the steel deck lower wing plate 201 when the first straightening arm 221 rotates.

In the present embodiment, the first driving mechanism 21 is configured as a first hydraulic cylinder, which can extend downward and apply downward pressure to the end of the first straightening arm 221 away from the first support base 222, thereby serving as an output mechanism for downward straightening power.

The first straightening arm 221 is rotatably connected to the first support base 222 through a rotating shaft, and when the first hydraulic cylinder applies downward pressure to the first straightening arm 221, the first straightening arm 221 can rotate around the first support base 222. And because the lower wing plate 201 of the steel platform truck is positioned on the rotating path of the first straightening arm 221, the first straightening arm 221 applies a downward straightening force to the lower wing plate 201 of the steel platform truck in the rotating process, thereby realizing the straightening of the lower wing plate 201 of the steel platform truck.

When the hydraulic cylinder is used specifically, the first hydraulic cylinder can be in communication connection with a control switch (not shown in the figure) through a control module (not shown in the figure), and the control switch can adopt a valve rod or a button and other structures. An operator can drive the first hydraulic cylinder only by operating the valve rod or pressing the button, and the straightening work is completed, so that the straightening efficiency is greatly improved.

In addition, since the first straightening arm 221 amplifies the driving force applied by the first hydraulic cylinder by using the lever principle, not only can the straightening efficiency be improved, but also the time and labor can be saved, and the volume of the device can be further reduced, thereby reducing the manufacturing cost.

In some embodiments, the first straightening arm 221 includes an arm body 2211 and a pressing head 2212, wherein one end of the arm body 2211 along the longitudinal direction thereof is rotatably connected to the first supporting seat 222, and the other end thereof is engaged with the first driving mechanism 21. The ram 2212 is formed by extending the arm body 2211 outward, and can abut against the upper surface of the lower wing plate 201 of the steel deck.

Specifically, the ram 2212 is configured as a hook-shaped structure extending upward from the arm body 2211 to apply a straightening force to the upper surface of the lower wing plate 201 of the steel platform car. When the arm body 2211 is rotated downward by the pressure of the first hydraulic cylinder 211, the pressing head 2212 is rotated downward in synchronization with the arm body 2211, and thereby abuts against the upper surface of the lower wing plate 201 of the steel platform car, applying a downward straightening force thereto.

In some embodiments, the first straightening mechanism 22 includes an operating position and a non-operating position. When the first straightening mechanism 22 is in the working position, the lower wing plate 201 of the steel flatcar is positioned on the rotating path of the first straightening arm 221, and when the first straightening mechanism 22 is in the non-working position, the lower wing plate 201 of the steel flatcar is positioned outside the rotating path of the first straightening arm 221.

To facilitate movement of the straightening apparatus 100 on the production line for straightening deformed parts at different positions on the production line, the first straightening mechanism 22 is set in the working position and the non-working position. The first straightening mechanism 22 can be switched between the working position and the non-working position, which places the first straightening mechanism 22 in the non-working position when the straightening arrangement 100 is moved on the production line. At this time, the steel deck lower blade 201 is located outside the turning path of the first straightening arm 221, and thus the first straightening arm 221 and the steel deck lower blade 201 can be prevented from interfering with each other when the straightening apparatus 100 is moved. When the straightening device 100 needs to straighten a certain position of the lower wing plate 201 of the steel platform car, the first straightening mechanism 22 is switched from the non-working position to the working position, and at the moment, the lower wing plate 201 of the steel platform car is positioned on the rotating path of the first straightening arm 221, so that the straightening of the lower wing plate 201 of the steel platform car can be realized through the first straightening arm 221.

Further, the first straightening device 20 comprises a moving mechanism 23, and the moving mechanism 23 is connected between the first straightening mechanism 22 and the fixed bracket 10 so as to switch the first straightening mechanism 22 between the working position and the non-working position. The first straightening mechanism 22 can be conveniently and quickly controlled to be switched between the working position and the non-working position by controlling the moving mechanism 23, and the working efficiency is improved.

Furthermore, the moving mechanism 23 includes a moving cylinder 231 and a connecting member (not shown in the figure), the moving cylinder 231 is fixed on the fixed bracket 10, the connecting member is connected between the first straightening mechanism 22 and the moving cylinder 231, and the moving cylinder 231 can drive the first straightening mechanism 22 to switch between the working position and the non-working position.

Specifically, in the embodiment, the connecting member is a connecting spring, the moving cylinder 231 and the connecting member are both disposed at the bottom of the fixing bracket 10, and the connecting member is connected between the moving cylinder 231 and the first supporting seat 222. The fixed support 10 is provided with a chute, the first support seat 222 is arranged in the chute and can be driven by the moving cylinder 231 to move along the chute, so that the first support seat 222 and the first straightening arm 221 are switched between the working position and the non-working position, and the influence on the moving transportation of the steel platform vehicle on the assembly line is avoided.

In some embodiments, the first straightening device 20 comprises a restoring mechanism 24, and the restoring mechanism 24 is fixed on the fixed bracket 10 and is positioned at one end of the first straightening arm 221, which faces away from the first supporting seat 222 along the longitudinal direction thereof. The restoring mechanism 24 and the first driving mechanism 21 are located on the rotation path of the first straightening arm 221 and located on two sides of the first straightening arm 221.

Referring to fig. 3, fig. 3 is an enlarged view of the structure of the reset mechanism in an embodiment of the present invention.

Specifically, the restoring mechanism 24 includes a compression spring 241 and a connecting bolt 242, and the compression spring 241 is sleeved on the connecting bolt 242. When the first straightening arm 221 is located at the non-working position, the compression spring 241 located below the first straightening arm can jack the first straightening arm 221 upwards by a certain height, so that the pressing head 2212 at the moment is higher than the steel platform car lower wing plate 201, and interference between the pressing head 2212 and the steel platform car lower wing plate 201 is prevented when the first straightening arm 221 is switched from the non-working position to the working position. The tightness of the connecting bolt 242 can be adjusted, so that when the first straightening arm 221 is located at the non-working position, the compression spring 241 can control the height of the first straightening arm 221 which is jacked upwards, and the pressure head 2212 can be ensured to be higher than the height of the lower wing plate 201 of the steel platform vehicle.

When straightening downwards the strake 201 under the steel platform car, in order to ensure the straightening effect of the strake 201 under the steel platform car, the straightening force is often controlled to make the strake 201 under the steel platform car exceed the balance state to a certain extent, so that the strake 201 under the steel platform car can be prevented from continuing to warp upwards when certain elasticity recovers. But inevitably, in the process, an overkill situation occurs.

FIGS. 4 and 5 are schematic views each showing the overall structure of a straightening apparatus in an embodiment of the present invention.

Therefore, in order to solve the above-mentioned occurrence of the overzealous situation, the straightening apparatus 100 comprises a second straightening device 30 for providing an upward straightening force to the lower wing plate 201 of the steel platform car. Referring to fig. 4 and 5, the second straightening device 30 is disposed on the fixed frame 10 and includes a second driving mechanism 31 and a second straightening mechanism 32. The second straightening mechanism 32 includes a second straightening arm 321 and a second support seat 322, one end of the second straightening arm 321 along the longitudinal direction thereof is rotatably connected to the second support seat 322, and the other end thereof is matched with the second driving mechanism 31 to rotate around the second support seat 322 under the driving of the second driving mechanism 31. Further, the steel deck lower blade 201 is positioned on the rotation path of the second straightening arm 321, and when the second straightening arm 321 rotates, an upward straightening force can be applied to the steel deck lower blade 201.

Specifically, in the embodiment, the second straightening arm 321 is rotatably connected to the second supporting seat 322 through a rotating shaft. The second driving mechanism 31 is configured as a second hydraulic cylinder, and is located at one end of the second straightening arm 321 away from the second supporting seat 322 along the longitudinal direction thereof, and is located below the second straightening arm 321. Thus, the second hydraulic cylinder can provide upward pressure to the second straightening arm 321, so that the second straightening arm 321 can abut against the lower surface of the lower wing plate 201 of the steel platform car and apply upward straightening force thereto.

In addition, the second straightening arm 321 also amplifies the pressure applied thereto by the second hydraulic cylinder by using the principle of leverage, thereby improving the straightening efficiency.

Specifically, the second hydraulic cylinder can also be in communication connection with a control switch through a control module, and the control switch can adopt a valve rod or a button and the like. An operator can drive the second hydraulic cylinder only by operating the valve rod or pressing the button, and the straightening work is completed, so that the straightening efficiency is greatly improved.

In some embodiments, the end of the second straightening arm 321 connected to the second support base 322 can abut against the lower surface of the lower wing plate 201 of the steel platform car to provide an upward straightening force to the lower surface of the lower wing plate 201 of the steel platform car. Because the second hydraulic cylinder and the second supporting seat 322 are respectively located at two ends of the second straightening arm 321, when the second hydraulic cylinder applies upward pressure to one end of the second straightening arm 321, the second straightening arm 321 rotates by taking the rotating shaft of the second supporting seat 322 as a fulcrum, and can be abutted against the lower surface of the lower wing plate 201 of the steel platform car in the rotating process, so that upward straightening force is applied to the lower surface.

In some embodiments, the second straightening device 30 comprises a clamping mechanism 33, and the clamping mechanism 33 is arranged on the fixed bracket 10 and clamps the lower wing plate 201 of the steel platform car therein. When the second straightening arm 321 applies an upward straightening force to the lower wing plate 201 of the steel deck car, the clamping mechanism 33 can provide a clamping force opposite to the straightening force.

When upwards straightening the lower wing plate 201 of the steel platform truck, when the second straightening arm 321 applies an upward straightening force to the lower surface of the lower wing plate 201 of the steel platform truck, if the applied straightening force is greater than the gravity of the steel platform truck, the steel platform truck is driven by the straightening force to move upwards, so that the straightening effect on the steel platform truck cannot be achieved.

Therefore, through clamping mechanism 33 to the strake 201 under the steel platform car press from both sides tightly, provide the clamp force opposite with straightening power, avoid the steel platform car to upwards move to strake 201 under the steel platform car that can be better goes on upwards straightening.

Further, the clamping mechanism 33 comprises two clamping ends arranged at intervals, a clamping space is formed between the two clamping ends, and the lower wing plate 201 of the steel platform car can be located in the clamping space. Therefore, the stability of the lower wing plate 201 of the steel platform car can be ensured, and the straightening effect is improved.

Further, the clamping mechanism 33 is rotatably connected to the fixed bracket 10 via a rotating shaft, and the clamping mechanism 33 has a clamping position and a non-clamping position during rotation. When the clamping mechanism 33 is in the clamping position, the lower wing plate 201 of the steel platform car is positioned in the clamping space. When the clamping mechanism 33 is in the non-clamping position, the lower wing plate 201 of the steel platform car is positioned outside the clamping space.

When the steel platform vehicle moves on the production line, in order to avoid the mutual influence between the clamping mechanism 33 and the steel platform vehicle, the clamping mechanism 33 can rotate relative to the fixed support 10 through the rotating shaft. During rotation, the clamping mechanism 33 has a clamped position and a non-clamped position. When the steel flatcar moves on the assembly line, the clamping mechanism 33 is located at the non-clamping position, and at the moment, the lower wing plate 201 of the steel flatcar is located outside the clamping space, so that the clamping mechanism 33 and the steel flatcar cannot interfere with each other. When the steel platform truck needs to be straightened, the clamping mechanism 33 is switched from the non-clamping position to the clamping position, and at the moment, the lower wing plate 201 of the steel platform truck is positioned in the clamping space, so that the steel platform truck can be ensured to be kept stable in the straightening process.

In addition, FIG. 6 shows a schematic view of the structure of the straightening apparatus in an embodiment of the invention. It should be noted that, as shown in fig. 6, the straightening device 100 further comprises a moving wheel 40 arranged at the bottom of the fixed support 10, and the moving wheel 40 can be matched with the steel platform car assembly line so that the straightening device 100 can move on the assembly line to adjust the position of the straightening device 100 on the assembly line.

Based on the same concept as the straightening device 100, the straightening process is provided, and the straightening device 100 is adopted to straighten the lower wing plate 201 of the steel platform car. The straightening process comprises the following steps:

s10: positioning, placing the first straightening device 20 at a target position to be straightened, and adjusting the moving mechanism 23 to switch the first straightening mechanism 22 from the non-working position to the working position.

Specifically, the straightening apparatus 100 is placed on an existing rail wheel assembly line in a factory, and the position of the straightening apparatus 100 is adjusted so that the moving wheel 40 on the straightening apparatus 100 is aligned with the rail wheel assembly line. And then the moving cylinder 231 is controlled to drive the first straightening arm 221 to switch from the non-working position to the working position, so as to straighten.

S20: straightening downwards, the first straightening arm 221 is driven by the first driving mechanism 21 to rotate around the first supporting seat 222, so that the pressing head 2212 of the first straightening arm 221 is abutted to the upper surface of the target position, and a downward straightening force is applied to the upper surface of the target position.

Specifically, in this embodiment, a first hydraulic cylinder applies a downward pressure to the first straightening arm 221, so that the first straightening arm 221 rotates around the first supporting seat 222, and the pressing head 2212 abuts against the upper surface of the lower wing plate 201 of the steel platform car at the target position, so as to apply a downward straightening force thereto, thereby achieving downward straightening.

S30: and straightening upwards, controlling the rotation of the clamping mechanism 33 to switch the clamping mechanism 33 from the non-clamping position to the clamping position, so that the target position is positioned in the clamping space, driving the second straightening arm 321 to rotate around the second supporting seat 322 through the second driving mechanism 31, enabling the second straightening arm 321 to be abutted against the lower surface of the target position, and applying an upward straightening force to the lower surface of the target position.

In the embodiment, the clamping mechanism 33 is first controlled to rotate to switch from the non-clamping position to the clamping position, so that the lower wing plate 201 of the steel platform car at the target position is positioned in the clamping space. And then the second hydraulic cylinder is controlled to lift upwards, so that the second hydraulic cylinder applies upward pressure to the second straightening arm 321, the second straightening arm 321 is abutted to the lower surface of the lower wing plate 201 of the steel platform car, and an upward straightening force is applied to the second straightening arm 321, so that upward straightening is realized.

When the straightening device is used specifically, the straightening device 100 is firstly placed on the existing steel rail wheel assembly line in a factory, and the position of the straightening device 100 is adjusted, so that the movable wheel 40 on the straightening device 100 and the steel rail wheel assembly line are in the same straight line. And then the moving cylinder 231 is controlled to drive the first straightening arm 221 to switch from the non-working position to the working position, so as to straighten.

After the positioning of the straightening arrangement 100 is completed, the straightening work can be performed. Specifically, the first hydraulic cylinder is controlled to apply a downward pressure to the first straightening arm 221, so that the first straightening arm 221 rotates around the first supporting seat 222, and the pressing head 2212 abuts against the upper surface of the lower wing plate 201 of the steel platform car at the target position to apply a downward straightening force to the upper surface, so as to achieve downward straightening.

After the downward straightening is completed, if the lower wing plate 201 of the steel platform car is excessively inclined downwards, the steel platform car is further straightened upwards by the second straightening device 30.

Specifically, the clamping mechanism 33 is first controlled to rotate so as to be switched from the non-clamping position to the clamping position, so that the steel deck lower wing plate 201 at the target position is located in the clamping space. And then the second hydraulic cylinder is controlled to lift upwards, so that the second hydraulic cylinder applies upward pressure to the second straightening arm 321, the second straightening arm 321 is abutted to the lower surface of the lower wing plate 201 of the steel platform car, and an upward straightening force is applied to the second straightening arm 321, so that upward straightening is realized. So far, the whole straightening process of the lower wing plate 201 of the steel platform car can be completed.
