Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete prefabricated parts, in particular to a straightening device and a mobile straightening device. BACKGROUND

[0002] At present, the lower wing plate of a PC (Precast Concrete, concrete prefabricated part) construction plant steel platform vehicle generally has a deformation problem, and the longer the use time is, the more serious the deformation is. The lower wing plate is in long-term contact with the rail wheel and is a main stress part of the steel platform vehicle, and the deformation mainly occurs between the rib plates and is manifested as the wing plate being warped upward. The deformation of the lower wing plate seriously affects the service life of the steel platform vehicle and the production quality of the PC component. The existing straightening methods mainly include manual straightening and fixed straightening equipment straightening.

[0003] Manual straightening needs workers to use simple tools to straighten the lower wing plate, and the efficiency is relatively low, and it is time-consuming and laborious. The fixed straightening method uses a special device for straightening, and the existing device realizes downward and upward straightening by relying on two sets of mechanisms, and the cost is high. SUMMARY

[0004] Therefore, it is necessary to provide an efficient straightening device with upward and downward straightening functions and a mobile straightening device in view of the above problems.

[0005] A straightening device for straightening a steel frame, the steel frame comprising an upper wing plate and a lower wing plate opposite in a set direction; the straightening device comprising:

[0006] a support member having a support arm protruding in a first direction intersecting the set direction, for abutting against the upper wing plate;

[0007] a straightening member connected to the support member and configured to be controllably rotatable relative to the support member; the straightening member is arranged in the set direction with the support arm and is used for abutting against the lower wing plate;

[0008] When the straightening device is in a first use state in which the upper wing plate and the lower wing plate are jointly arranged between the support arm and the straightening member, the straightening member can apply a straightening force to the lower wing plate when controllably rotating, the straightening force being directed to the upper wing plate; when the straightening device is in a second use state in which the support arm and the straightening member are arranged between the upper wing plate and the lower wing plate, the straightening member can apply a straightening force to the lower wing plate when controllably rotating, the straightening force being directed away from the upper wing plate.

[0009] The straightening device is used in contact with the upper wing plate by the supporting arm. Since the upper wing plate has high structural strength, the straightening part can obtain a stable supporting force through the supporting arm. The straightening part is used in contact with the lower wing plate, and when the straightening part rotates relative to the supporting part, a straightening force can be applied to the lower wing plate under the support of the supporting part. Specifically, when the straightening device is in a first use state in which the supporting arm and the straightening part clamp the upper wing plate and the lower wing plate, the rotation of the straightening part can generate a straightening force on the lower wing plate directed to the upper wing plate, so as to realize the upward straightening of the lower wing plate. When the straightening device is in a second use state in which the supporting arm and the straightening part are arranged between the upper wing plate and the lower wing plate, the rotation of the straightening part can generate a straightening force on the lower wing plate directed away from the upper wing plate, so as to realize the downward straightening of the lower wing plate.

[0015] In one of the embodiments, the first straightening part is provided with a first profile and a second profile which are arranged adjacent to each other in the first direction and are directed to the second straightening part.

[0016] When the straightening device is in the first use state, the first profile is in contact with the lower wing plate; and when the straightening device is in the second use state, the second profile jointly clamps the lower wing plate with the second straightening part.

[0017] In one of the embodiments, the first straightening part is further provided with a limiting protrusion between the first profile and the second profile, and the limiting protrusion is used for limiting the side of the steel frame away from the second straightening part.

[0040] Please refer to Figure 1As described in the background, the steel frame 100 of the steel platform car generally comprises an upper wing plate 101 and a lower wing plate 103 opposite in a set direction, a web plate 105 connected between the upper wing plate 101 and the lower wing plate 103, and a plurality of rib plates 107 arranged in the space enclosed by the upper wing plate 101, the lower wing plate 103 and the web plate 105. In the actual state, the upper wing plate 101 is the upper plate surface supported, while the lower wing plate 103 is in long-term contact with the rail wheel and is the main force-bearing part of the steel frame 100, and lacks support below. Although the rib plates 107 can strengthen the lower wing plate 103 to a certain extent, the lower wing plate 103 between the rib plates 107 will still be warped. Therefore, a straightening device 300 is needed to straighten the warped lower wing plate 103.

[0041] Please refer to Figure 2 and Figure 3 , the straightening device 300 provided by an embodiment of the present application is used for correcting the steel frame 100. The straightening device 300 comprises a support member 31 and a straightening member 33. The support member 31 has a support arm 311 protruding in a first direction intersecting the set direction, and is used for abutting against the upper wing plate 101. The straightening member 33 is connected to the support member 31 and is configured to be capable of being controlled to rotate relative to the support member 31. The straightening member 33 is arranged in the set direction and is used for abutting against the lower wing plate 103. When the straightening device 300 is in a first use state in which the upper wing plate 101 and the lower wing plate 103 are jointly clamped between the support arm 311 and the straightening member 33, the straightening member 33 can apply a straightening force directed to the upper wing plate 101 to the lower wing plate 103 when being controlled to rotate. When the straightening device 300 is in a second use state in which the support arm 311 and the straightening member 33 are clamped between the upper wing plate 101 and the lower wing plate 103, the straightening member 33 can apply a straightening force directed away from the upper wing plate 101 to the lower wing plate 103 when being controlled to rotate.

[0042] The set direction corresponds to the up-down direction of Figure 2 and Figure 3 , and the first direction corresponds to the left-right direction of Figure 2 and Figure 3 . The connection between the straightening member 33 and the support member 31 can form a force conduction between the straightening member 33 and the support member 31, so that the support member 31 can support the straightening member 33.

[0043] Wherein, when the first use state is defined, the surface of the support arm 311 abutting against the upper wing plate 101 is the first support surface, and the surface of the straightening member 33 abutting against the lower wing plate 103 is the first straightening surface. When the second use state is defined, the surface of the support arm 311 abutting against the lower wing plate 103 is the second support surface, and the surface of the straightening member 33 abutting against the lower wing plate 103 is the second straightening surface. It is known that, in use, the first support surface and the first straightening surface are spaced apart and opposite in the set direction, and together define a nip for clamping the upper wing plate 101 and the lower wing plate 103. The second support surface and the second straightening surface are spaced apart and opposite in the set direction, and together define a support for supporting between the upper wing plate 101 and the lower wing plate 103. With the controlled rotation of the straightening member 33 relative to the support member 31, in the first use state, the nip is reduced to exert a force on the lower wing plate 103 directed to the upper wing plate 101, so that the lower wing plate 103 is deformed upward to achieve upward straightening. In the second use state, the support is increased to exert a force on the lower wing plate 103 directed away from the upper wing plate 101, so that the lower wing plate 103 is deformed downward to achieve downward straightening.

[0044] The above straightening device 300, in use, abuts the support arm 311 against the upper wing plate 101, and since the upper wing plate 101 has high structural strength, the straightening member 33 connected to the support member 31 can obtain a stable support force through the support arm 311. The straightening member 33 is used to abut against the lower wing plate 103, and when it rotates relative to the support member 31, it can exert a straightening force on the lower wing plate 103 under the support of the support member 31. Specifically, when the straightening device 300 is in the first use state in which the support arm 311 and the straightening member 33 clamp the upper wing plate 101 and the lower wing plate 103, the rotation of the straightening member 33 can exert a straightening force on the lower wing plate 103 directed to the upper wing plate 101, to achieve upward straightening of the lower wing plate 103. When the straightening device 300 is in the second use state in which the support arm 311 and the straightening member 33 support between the upper wing plate 101 and the lower wing plate 103, the rotation of the straightening member 33 can exert a straightening force on the lower wing plate 103 directed away from the upper wing plate 101, to achieve downward straightening of the lower wing plate 103.

[0045] Further, the support arm 311 includes a first support arm 3111 and a second support arm 3113, which are spaced apart in the set direction. When the straightening device 300 is in the first use state, the surface of the first support arm 3111 facing the second support arm 3113 abuts against the upper wing plate 101. When the straightening device 300 is in the second use state, the surface of the second support arm 3113 facing the first support arm 3111 abuts against the upper wing plate 101.

[0046] The straightening member 33 comprises a first straightening part 331 and a second straightening part 333, which are arranged in a set direction. When the straightening device 300 is in the first use state, the surface of the first straightening part 331 facing the second straightening part 333 abuts against the lower wing plate 103. When the straightening device 300 is in the second use state, the surface of the second straightening part 333 facing the first straightening part 331 abuts against the lower wing plate 103.

[0047] The first supporting surface is formed on the side of the first supporting arm 3111 facing the second supporting arm 3113, and the second supporting surface is formed on the side of the second supporting arm 3113 facing the first supporting arm 3111. The first straightening surface is formed on the side of the first straightening part 331 facing the second straightening part 333, and the second straightening surface is formed on the side of the second straightening part 333 facing the first straightening part 331.

[0048] By arranging the first supporting arm 3111, the second supporting arm 3113, the first straightening part 331 and the second straightening part 333, the straightening device 300 can achieve the purpose of clamping the upper wing plate 101 and the lower wing plate 103 by the first supporting arm 3111 and the first straightening part 331, and supporting between the upper wing plate 101 and the lower wing plate 103 by the first supporting arm 3111 and the second straightening part 333. It can be understood that in other embodiments, the supporting arm 311 can only comprise the first supporting arm 3111 and / or the straightening member 33 can only comprise the first straightening part 331, and the distance between the first supporting arm 3111 and the first straightening part 331 can be adjusted. When the distance between the first supporting arm 3111 and the first straightening part 331 is large, the straightening device 300 is in the first use state, clamping the upper wing plate 101 and the lower wing plate 103. As the distance between the first supporting arm 3111 and the first straightening part 331 decreases, the straightening device 300 switches to the second use state, and can be supported between the upper wing plate 101 and the lower wing plate 103.

[0049] In some embodiments, the straightening device 300 further comprises a driving member, and the straightening member 33 is connected to the supporting member 31 via the driving member, for driving the straightening member 33 to rotate relative to the supporting member 31.

[0050] The driving member drives the straightening member 33 to rotate as a power unit, and completes the straightening work. It can be a hydraulic drive device, a motor, etc., which is not limited here.

[0051] In a specific embodiment, the driving member is a hydraulic cylinder 351 of the hydraulic station 35, and the two ends of the hydraulic cylinder 351 are respectively rotatably connected to the supporting member 31 and the straightening member 33, and the straightening member 33 is driven to rotate relative to the supporting member 31 by changing the distance between the two ends of the hydraulic cylinder 351.

[0052] The steel frame 100 of a common steel platform vehicle has a Q235B material for the two side main beams, a yield strength of 235Mpa, and a thickness of 14mm at the middle of the wing plate, which requires a large correction force. In general, direct manual correction cannot achieve the desired effect, and the straightening part needs to be heated first, then manually corrected, and finally repaired in appearance. The process is relatively complex, the correction efficiency is low, and the labor intensity of workers is large. The hydraulic cylinder 351 has a large power-to-volume ratio, which can provide a large output force to meet the straightening requirements under the premise of occupying a small volume.

[0053] Further, the straightening device 300 further comprises a rotating shaft 36 detachably connecting the straightening part 33 and the support part 31, and the straightening part 33 is rotatably connected to the support part 31 via the rotating shaft 36. When the straightening device 300 is in the first use state, the rotating shaft 36 rotatably connects the straightening part 33 and the support part 31, and the straightening part 33 is controlled to rotate around the rotating shaft 36 relative to the support part 31.

[0054] The support part 31 extends in a set direction, and one end of the support part 31 in the set direction is connected to the driving part, and the other end is provided with an axle hole K for the rotating shaft 36 to pass through. The first end of the straightening part 33 forms a first straightening part 331 and a second straightening part 333, and the second end is used to connect with the driving part. A semicircular notch Q is provided between the two ends of the straightening part 33 and matches the axle hole K. The rotating shaft 36 rotatably connects the support part 31 and the straightening part 33 through the axle hole K and the semicircular notch Q. The distance between the semicircular notch Q and the first end is less than the distance between the semicircular notch Q and the second end, so as to further amplify the output force of the driving part by means of the lever principle in the first use state. At this time, the straightening part 33 acts as a force arm, and the rotating shaft 36 acts as a fulcrum.

[0055] Further, the first straightening part 331 and the second straightening part 333 are controlled to change the distance between each other in the set direction. When the straightening device 300 is in the first use state, the first straightening part 331 abuts against the lower wing plate 103; when the straightening device 300 is in the second use state, the rotating shaft 36 is detached from the straightening part 33 and the support part 31, and the first straightening part 331 and the second straightening part 333 jointly clamp the lower wing plate 103.

[0056] When the straightening device 300 is in the first use state, the driving member applies force to the straightening member 33, the straightening member 33 acts as a force arm, the rotating shaft 36 acts as a fulcrum, and the first straightening part 331 applies a straightening force directed to the upper wing plate 101 to the lower wing plate 103. When the straightening device 300 is in the second use state, the straightening member 33 and the supporting member 31 are in a disassembled state, but force can be transmitted between the two through the driving member, and the supporting member 31 can provide a supporting force to the straightening member 33 during the straightening process through the driving member. The straightening device 300 clamps the lower wing plate 103 by adjusting the distance between the first straightening part 331 and the second straightening part 333, and when the straightening member 33 rotates under the action of the driving member, the lower wing plate 103 is driven to rotate away from the upper wing plate 101. At this time, the straightening part can be regarded as a force arm, and the front end of the first straightening part 331 and the second straightening part 333 clamping the lower wing plate 103 are regarded as a fulcrum, and the second straightening part 333 applies a straightening force to the lower wing plate 103 away from the upper wing plate 101. In another aspect, the first straightening part 331 and the second straightening part 333 jointly clamp the lower wing plate 103, which is essentially to prevent the second straightening part 333 from slipping relative to the lower wing plate 103 when the straightening force is applied to the lower wing plate 103 through the formed support opening.

[0057] By changing the force application point and the force application mode, the hydraulic cylinder 351 can output a one-way force to achieve bidirectional straightening of the lower wing plate 103 upward and downward.

[0058] In a specific embodiment, the second straightening part 333 includes a fixed unit 3331 fixed relative to the first straightening part 331 and a movable unit 3333 movable relative to the fixed unit 3331 in a set direction, the movable unit 3333 is connected to the fixed unit 3331 through a lead screw 3335, and the movable unit 3333 is moved relative to the fixed unit 3331 by rotating the lead screw 3335 to push the movable unit 3333 to move relative to the first straightening part 331 in a set direction to change the distance. In other embodiments, the distance between the first straightening part 331 and the second straightening part 333 can also be adjusted to clamp the lower wing plate 103 by other means, such as spring clamps, bolt clamps, etc., which are not limited here.

[0059] Specifically, a limiting connecting member 37 (as shown) is arranged between the supporting arm 311 and the straightening member 33, and the limiting connecting member 37 is used to support the supporting arm 311 and the straightening member 33 to maintain a certain basic distance and angle when the rotating shaft 36 is disassembled, facilitating subsequent operations. Figure 5

[0060] ​In some embodiments, the first straightening part 331 has a first profile 3311 and a second profile 3313 arranged adjacently in the first direction and arranged towards the second straightening part 333. When the straightening device 300 is in the first use state, the first profile 3311 abuts against the lower wing plate 103. When the straightening device 300 is in the second use state, the second profile 3313 cooperates with the second straightening part 333 to clamp the lower wing plate 103.

[0061] When the straightening device 300 switches from the first use state to the second use state, the position distance between the first support arm 3111 and the second support arm 3113 and the first straightening part 331 and the second straightening part 333 changes, and the working unit switches from the first support arm 3111 and the first straightening part 331 with a relatively farther distance to the second support arm 3113 and the second straightening part 333 with a relatively closer distance. To adapt to this change in shape, the working surface of the first straightening part 331 is divided into the first profile 3311 and the second profile 3313, which are different in function. The first profile 3311 is the first straightening surface that cooperates with the first support surface, and the second profile 3313 is the second straightening surface that cooperates to bear the clamping action.

[0062] Further, the first straightening part 331 is further configured with a limiting protrusion 3315 between the first profile 3311 and the second profile 3313, which is used to limit the side of the steel frame 100 away from the second straightening part 333.

[0063] Under the limiting action of the limiting protrusion 3315, it can further prevent the second straightening part 333 from slipping off the lower wing plate 103 in the second use state. At the same time, the limiting protrusion 3315 can be regarded as the fulcrum when the second straightening part 333 straightens the lower wing plate 103 downward. Specifically, the limiting protrusion 3315 limits the side of the steel frame 100 away from the second straightening part 333, i.e., the inner side of the web plate 105.

[0064] It can be understood that in other embodiments, a driving member that outputs driving force in two directions can also be used to drive the straightening member 33 to rotate in two directions, corresponding to the first use state and the second use state, respectively, to generate forces in two directions on the lower wing plate 103.

[0065] In some embodiments, the straightening device 300 further comprises a straightening measuring scale 39, which is rotatably connected to the support member 31 and keeps its longitudinal direction perpendicular to the horizontal plane under the action of gravity.

[0066] The straightening measuring ruler 39 keeps its longitudinal direction vertical to the horizontal plane under the action of gravity to measure the distance between the upper wing plate 101 and the lower wing plate 103, which directly reflects the straightening state of the lower wing plate 103. When the straightening operation is performed, the distance between the upper wing plate 101 and the lower wing plate 103 is measured by the straightening measuring ruler 39, and then compared with the distance in the normal state to determine whether the lower wing plate 103 is in the state of upward warping, downward deformation or normal state, and accordingly select the corresponding operation.

[0067] When the lower wing plate 103 needs to be upward straightened, the straightening device 300 keeps the straightening member 33 and the support member 31 connected by the rotating shaft 36, and first abuts the surface of the first support arm 3111 facing the second support arm 3113 to the upper side of the upper wing plate 101, and the first profile 3311 of the straightening member 33 is located at the lower side of the lower wing plate 103. The first profile 3311 is driven by the hydraulic cylinder 351 to gradually approach the lower side of the lower wing plate 103 until abutting. At this time, the upper wing plate 101 and the lower wing plate 103 are clamped between the first support arm 3111 and the first profile 3311. Continue to operate the hydraulic cylinder 351 to apply force, and then a straightening force upward is generated to the lower wing plate 103 through the first profile 3311 with the straightening member 33 as the force arm and the rotating shaft 36 as the fulcrum under the support of the support member 31, so as to realize the upward straightening. By observing the straightening measuring ruler 39, when the distance between the upper wing plate 101 and the lower wing plate 103 reaches the target value, stop applying force, and retract the hydraulic cylinder 351 to make the first profile 3311 away from the lower wing plate 103, so as to make the straightening device 300 slide along the upper wing plate 101 to the next position and continue the straightening work.

[0068] When the lower wing plate 103 needs to be downward straightened, first disengage the rotating shaft 36. The surface of the second support arm 3113 facing the first support arm 3111 abuts to the lower side of the upper wing plate 101, the limiting protrusion 3315 is limited to the inner side of the web plate 105, and the movable unit 3333 and the second profile 3313 clamp the lower wing plate 103 by adjusting the lead screw 3335. At this time, the hydraulic cylinder 351 is operated to apply force to the straightening member 33, and the straightening member 33 is driven by the hydraulic cylinder 351 to drive the clamped lower wing plate 103 to rotate downward under the support of the support member 31. By observing the straightening measuring ruler 39, when the distance between the upper wing plate 101 and the lower wing plate 103 reaches the target value, stop applying force. Loosen the lead screw, retract the hydraulic cylinder 351, and abut the upper side of the lower wing plate 103 to the fixed unit 3331, so as to make the straightening device 300 move along the upper side of the lower wing plate 103 to the next position and continue the straightening work.

[0069] In addition to the problems described in the background section, traditional straightening equipment is fixedly installed on the rail conveyor belt, working in conjunction with the conveyor belt to achieve straightening. After straightening at a certain position is completed, the steel trolley is moved along the rail conveyor belt to the next position for straightening. However, the installation of the equipment on the rail conveyor belt may interfere with the original production equipment, affecting production. Moreover, one piece of equipment can only be used to straighten steel frames 100 on the same production line. If one piece of equipment is installed on each production line, the straightening cost will increase significantly.

[0070] For the above issues, please refer to Figures 4 to 7 The present invention also provides a mobile straightening device 500, which includes the aforementioned straightening device 300 and a mobile platform 501. The straightening device 300 is mounted on the mobile platform 501, and the mobile platform 501 can be moved in a controlled manner.

[0071] The straightening device 300 can move along with the mobile platform 501, achieving straightening at different positions without being restricted by the continuous flow of rails. Furthermore, the main components of the hydraulic station 35, excluding the hydraulic cylinder 351, such as the oil tank and motor, are also mounted on the mobile platform 501 and move synchronously.

[0072] Furthermore, the mobile platform 501 has a mounting bracket 503, which includes a column 5031, a boom 5033, and a winch 5035. The column 5031 is mounted on the mobile platform 501, and the winch 5035 is connected to the straightening device 300 via the boom 5033 and can operably adjust the height of the straightening device 300.

[0073] The straightening device 300 is suspended on the boom 5033 via the winch rope of the winch 5035 and the pulley block 5037. The user can adjust the height of the straightening device 300 through the winch 5035 to adapt to the height of the upper wing plate 101 and the lower wing plate 103, and coordinate with the state switching of the straightening device 300 to ensure that the straightening device 300 is in the best working position.

[0074] Furthermore, the height of the column 5031 and the length of the boom 5035 can be controlled and adjusted to position the straightening equipment 300 in a suitable location for straightening operations.

[0075] Understandably, in order to achieve normal movement, the mobile platform 501 typically includes a support platform 5011, casters 5012 mounted on the bottom of the support platform 5011, and handles 5013 mounted on the support platform 5011, etc., which will not be described in detail here.

[0076] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0077] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
