Description

Technical Field

[0001] The invention relates to an assembled bidirectional anti-deformation reinforcement for a double-ear plate structure and an anti-deformation control method, belonging to the technical field of welding engineering. Background Art

[0002] Due to the large angular deformation of the boom, dipper arm and turntable cylinder ear plates after welding, the perpendicularity of the ear plates and the processed shaft holes is difficult to ensure, resulting in a large bell-mouth gap between the ear plates and the cylinder end faces during assembly. The ear plates need to be flame-corrected or ground. The average rework time for a single unit is 0.5 hours, which seriously reduces production efficiency.

[0003] At present, the control method adopted for the welding deformation of the ear plates of the excavator boom, dipper arm and turntable cylinder is welding process reinforcement, that is, when the structural parts are assembled, a section of solid square steel with a cross-section of 40*40mm is used, and its left and right ends are welded together with the left and right ear plates respectively, so that the left and right ear plates are connected into a whole, so as to enhance the rigidity constraint of the ear plate welding joint and achieve the purpose of reducing the welding deformation of the ear plate.

[0004] The above-mentioned welded tie bars have the following main disadvantages: 1. It is impossible to achieve anti-deformation control. When the welding shrinkage force is large or the ear plate stiffness is insufficient, the ear plate will undergo a certain elastic bending deformation. After the tie bar is removed, the rebound is large, and the deformation control effect is poor; 2. The installation and disassembly process of the tie bar involves welding, gouging, and grinding operations, which is time-consuming and labor-intensive; 3. Due to the limited space on the inner side of the ear plate and the surface quality requirements, the tie bar can only be welded to the top of the ear plate. The force application point is far away from the bottom of the ear plate, the force arm is long, the restraint on the ear plate welding joint is low, and the deformation control effect is poor; 4. After the tie bar has been used for a period of time, due to repeated welding and gouging, the surface becomes uneven and there are many inclusions. The strength of the weld connection cannot be guaranteed, resulting in frequent cracking and low reliability of the tie bar. Summary of the Invention

[0005] The purpose of the present invention is to provide an assembled bidirectional anti-deformation tie rod for a double-ear plate structure, which can realize left and right bidirectional anti-deformation control of the ear plate, meet the verticality requirements of the ear plate and the processed shaft hole, avoid post-weld correction, and significantly improve production efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides an assembled bidirectional anti-deformation tie bar for a double-ear plate structure, comprising: an F-shaped main body, a rotating support arm assembly, a latch assembly, a rotating limit assembly and a horizontal tightening component;

[0013] There are three horizontal tightening components, which are respectively located at the lower ends of the two rotating support arm assemblies and the lower ends of the extending arms at the ends of the F-shaped main body;

[0014] The horizontal tightening components at the lower ends of the two rotating support arm assemblies are arranged opposite to each other and are used to tighten and fix the cylinder ear plates from the left and right sides, and to apply force to control the anti-deformation;

[0017] The pressure head connector is located inside the pressure head, and the pressure head and the pressure head connector are movably connected via a stepped thread. The end face of the pressure head serves as the contact surface with the cylinder ear plate during reverse deformation control. When the cylinder ear plate is reversely deformed, the pressure head rotates at a certain angle along with the ear plate, so that the end face of the pressure head always closely fits the surface of the cylinder ear plate.

[0018] The tightening bolt is movably connected to the pressure head connector via a stepped thread; the tightening bolt is used to apply force to the cylinder ear plate during anti-deformation control;

[0019] The plane bearing is located between the tightening bolt and the pressure head connector and is directly strung on the tightening bolt.

[0020] Furthermore, rolling bearings are installed on the sides of the rotation support arm assembly and the rotation limit assembly that are in contact with the latch assembly.

[0021] Furthermore, the latch assembly includes a pull rod, a latch, a spring and a bolt.

[0022] The pull rod, latch and bolt are installed together in sequence, a spring is sleeved on the bolt, and the spring and bolt are inserted into the slot hole of the F-shaped main body to form a reset mechanism.

[0023] Furthermore, a surface of the latch adjacent to the rotating support arm assembly is wedge-shaped.

[0024] Furthermore, a portable handle is provided on the surface of the F-shaped main body.

[0026] The setting pin components are marked as 3a and 3b respectively, the horizontal tightening parts are marked as 5a, 5b and 5c from left to right respectively, the middle extension arm of the F-type body is marked as 1a, and the end extension arm is marked as 1b;

[0027] The method for controlling the inward reverse deformation of the cylinder lug plate comprises:

[0028] When assembling the cylinder ear plates, place the tie bars on the top of the ear plates. The left ear plate is located between the horizontal tightening parts 5a and 5b, and the outer end face of the left ear plate is in close contact with the pressure head of the horizontal tightening part 5a. The right ear plate is located between the middle extension arm 1a and the horizontal tightening part 5c, and the inner end face of the right ear plate and the middle extension arm 1a maintain a distance of the ear plate's inward reverse deformation.

[0029] First, tighten the horizontal tightening component 5b so that it is close to the inner side of the left ear plate, and then tighten the horizontal tightening component 5c so that the inner side of the right ear plate is against the arc surface of the middle extension arm 1a, so that the ear plate is deformed inward;

[0030] The method for controlling outward reverse deformation of the cylinder lug plate comprises:

The right ear plate is located between the horizontal tightening component 5c and the middle extension arm 1a, and the inner end face of the right ear plate is close to the middle extension arm 1a. The left ear plate is located between the horizontal tightening component 5a and the horizontal tightening component 5b, and the inner end face of the left ear plate is close to the pressure head of the horizontal tightening component 5b. The outer end face and the horizontal tightening component 5a maintain a distance of the outward reverse deformation of the ear plate.

[0032] First tighten the horizontal tightening component 5c, and then tighten the horizontal tightening component 5b, so that the outer side of the left ear plate is against the horizontal tightening component 5a, completing the reinforcement clamping and the outward reverse deformation of the ear plate.

[0033] Furthermore, the distance of the inward reverse deformation and the distance of the outward reverse deformation are determined by the position of the horizontal tightening component 5a. The distance is adjusted by moving the horizontal tightening component 5a left and right to control the reverse deformation.

[0034] Furthermore, the method further comprises:

[0035] Under the control of inward reverse deformation, after the welding of the ear plates on both sides is completed, the latch assembly 3a is pulled out, the left ear plate rebounds outward, and the support arm assembly 2a is rotated clockwise to release the rebound force of the left ear plate. The position of the horizontal tightening component 5a remains unchanged. The horizontal tightening component 5b and the horizontal tightening component 5c are moved to the right by rotating the tightening bolts in the opposite direction, and the tie bar is removed;

[0036] Under the control of outward reverse deformation, after the welding of the ear plates on both sides is completed, pull out the pin assembly 3b, the left ear plate rebounds inward, rotate the support arm assembly 2b counterclockwise, the rebound force of the left ear plate is released, and the position of the horizontal tightening component 5a remains unchanged. Move the horizontal tightening component 5b and the horizontal tightening component 5c to the right by rotating the tightening bolt in the opposite direction, and remove the tie rod.

In addition, the horizontal tightening component and the force-relieving component are arranged with plane bearings and rolling bearings to convert sliding friction into rolling friction, greatly saving physical effort.

DETAILED DESCRIPTION

[0052] The present invention will be further described below. The following examples are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0053] One embodiment of the present invention provides a prefabricated bidirectional anti-deformation reinforcement for a double-ear plate structure, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it includes an F-shaped body 1, a rotating support arm assembly 2, a latch assembly 3, a rotation limiting assembly 4 and a horizontal tightening component 5;

[0054] Specifically, one end surface of the middle extending arm of the F-shaped body is a flat surface, and the other end surface is a curved surface.

[0055] The rotating support arm assembly 2, the latch assembly 3 and the rotating limit assembly 4 are installed on the F-shaped main body 1 to form a force relief component for controlling the rear force relief of the anti-deformation of the ear plate.

[0056] In this embodiment, the force relief components are symmetrically distributed in two groups, one group is located at the end of the F-shaped body, and the other group is located on one side of the plane end surface of the F-shaped body close to the middle extension arm.

[0057] Furthermore, the two rotating support arm assemblies 2 are respectively installed in the rectangular slots provided on the F-shaped main body 1 through the pin shafts 7 and can rotate in the rectangular slots.

[0058] The latch assembly 3 is installed on the inner side of the rotating support arm assembly 2, and the rotation limiting assembly 4 is installed on the inner side of the latch assembly 3. The latch assembly and the limiting assembly are used to limit the rotating support arm assembly.

[0059] Two sets of force relief components enable bidirectional force relief of the cylinder lugs. After the lugs are welded, remove the latch assembly 3 from the force relief components and rotate the support arm assembly 2 around the central pin. This fully releases the lug's rebound force, enabling one-click removal of the tie bars.

[0060] In this embodiment, there are three horizontal tightening components 5, which are respectively located at the lower ends of the two rotating support arm assemblies and the lower ends of the extending arms at the end of the F-shaped main body.

[0061] The horizontal tightening components at the lower ends of the two rotating support arm assemblies are arranged relative to each other and are used to tighten and fix a cylinder ear plate from the left and right sides, and to apply force to achieve anti-deformation control.

[0062] The horizontal tightening component at the lower end of the extending arm at the end of the F-type body is arranged opposite to the arc surface of the extending arm in the middle of the F-type body, and is used to tighten and fix the other cylinder ear plate from the left and right sides, and apply force to achieve anti-deformation control.

[0063] This method has a shorter force arm, stronger constraint on the ear plate, better deformation control effect, and can achieve two-way anti-deformation control inside and outside the ear plate.

[0064] Furthermore, the horizontal tightening member 5 is as follows Figure 6 As shown, it includes a pressure head 13, a pressure head connector 14, a plane bearing 15 and a tightening bolt 16.

[0065] The pressure head connector is located inside the pressure head. The pressure head 13 and the pressure head connector 14 are movably connected through a step thread. The pressure head applies force to the ear plate to perform anti-deformation control.

[0066] When the ear plate is deformed in reverse, the pressing head 13 rotates with the ear plate at a certain angle so that the front end surface of the pressing head is always in close contact with the surface of the ear plate, maintaining a large force application area and avoiding indentations on the ear plate surface.

[0067] The tightening bolt 16 is movably connected to the pressure head connector 14 through a stepped thread. The plane bearing 15 is located between the tightening bolt 16 and the pressure head connector 14 and is directly strung on the tightening bolt 16. When the ear plate is clamped and anti-deformed, one side of the plane bearing 15 remains stationary with the pressure head 13, the pressure head connector 14 and the cylinder ear plate, and the other side rotates with the tightening bolt 16. That is, the sliding friction between the pressure head 13 and the ear plate is converted into rolling friction inside the plane bearing 15 through the plane bearing 15, making the clamping and anti-deformation of the ear plate more labor-saving.

[0068] Furthermore, the rotating support arm assembly 2, the rotating limit assembly 4 and the latch assembly 3 constitute a force relief component, and rolling bearings 8 are installed on the sides of the rotating support arm assembly 2 and the rotating limit assembly 4 that are in contact with the latch assembly 3, so that rolling friction replaces sliding friction, greatly reducing the insertion and removal resistance of the latch assembly 3.

[0069] Furthermore, the latch assembly 3 is as follows Figure 5 As shown, it includes a pull rod 9, a latch 10, a spring 11 and a bolt 12.

[0070] The pull rod 9, the latch pin 10 and the bolt 12 are sequentially mounted together, the spring 11 is sleeved on the bolt 12, and the spring 11 and the bolt 12 are inserted into the slot of the F-shaped main body 1 to form a reset mechanism.

[0071] When assembling the ear plates, insert the bolt 12 into the slot of the F-type main body 1, and limit the rotating support arm assembly through the latch assembly and the rotation limit assembly; after welding is completed, pull out the latch assembly, the ear plate rebounds outward, and the rotating support arm assembly rotates clockwise at a certain angle. The ear plate rebound force is completely released, and the latch assembly 3 automatically returns to its position under the action of the spring, and the rotating support arm assembly 2 resumes the limit, thereby realizing the rapid clamping and positioning of the reinforcement.

[0072] As a preferred embodiment, the latch 10 is designed as a single-sided wedge structure, that is, the side adjacent to the rotating support arm assembly 2 is designed to be stepped, and through an inclined transition, it is avoided that the limit of the rotating support arm disappears completely instantly when the latch 10 is pulled out, and violent swings occur under the action of the rebound force of the ear plate, hitting the F-type main body 1 and causing damage.

[0073] It should be noted that the height difference of the wedge-shaped surface of the pin 10 and the width of the rectangular slot on the F-shaped main body 1 for accommodating the rotating support arm assembly 2 are designed according to the actual maximum deformation of the cylinder ear plate, ensuring that the rotating support arm assembly 2 has sufficient rotation space, the ear plate rebound force can be fully released, and the tensioning bar can be easily disassembled.

[0074] Furthermore, a portable handle 6 is provided on the surface of the F-shaped main body 1 .

[0075] The working process of this embodiment is explained by taking the inward reverse deformation of the cylinder ear plate as an example. For the convenience of description and understanding, the left and right pin assemblies of the assembled tie rod are respectively marked as 3a and 3b, the three horizontal tightening parts are respectively marked as 5a, 5b, and 5c from left to right, and the F-type main body extension arms are respectively marked as 1a and 1b.

[0076] like Figure 7 As shown, when the cylinder ear plate is assembled, the tie rod is placed on the top of the ear plate through the convenient handle. The left ear plate is located between the horizontal tightening parts 5a and 5b, and the outer end face of the ear plate is close to the pressure head of 5a. The right ear plate is located between 1a and 5c, and the inner end face maintains a certain distance D from 1a. This distance is the inward anti-deformation amount of the ear plate. The distance D is determined by the position of 5a. Use a wrench to move 5a left and right to adjust the distance D to complete the anti-deformation amount setting. Then tighten 5b first to make it close to the inner side of the left ear plate, and then tighten 5c to make the inner side of the right ear plate counteract the arc surface of 1a to achieve the inward anti-deformation of the ear plate. Figure 8 As shown. After the lugs are welded, pull out the latch assembly 3a with both hands. The lugs will rebound outward. Rotate the support arm assembly 2a clockwise a certain angle to completely release the lug's rebound force. Position 5a remains unchanged. Move 5b and 5c to the right a certain distance to remove the tie bars. For the same structural component, after determining the optimal amount of deflection through testing, keep 5a fixed in position during subsequent tie bar use. After the tie bars are in place, tighten 5c, then 5b.

[0077] The working process of this embodiment is described by taking the outward reverse deformation of the cylinder ear plate as an example.

[0078] like Figure 9 As shown, when assembling the cylinder ear plate, place the tie rod on the top of the ear plate through the convenient handle. The right ear plate is located between 5c and 1a, and the inner end face is close to 1a. The left ear plate is located between 5a and 5b, with the inner end face close to the pressure head of 5b, and the outer end face maintains a certain distance D from 5a. This distance is the outward anti-deformation of the ear plate. The distance D is determined by the position of 5a. Use a wrench to move 5a left and right to adjust the distance D to complete the anti-deformation setting. Then tighten 5c first, and then tighten 5b, so that the outer side of the left ear plate is against 5a, completing the tie rod clamping and the outward anti-deformation of the ear plate. Figure 10 As shown. After the lugs are welded, pull out the latch assembly 3b with both hands. The lugs will rebound inward. Rotate the support arm assembly 2b counterclockwise a certain angle to completely release the lug's rebound force. Position 5a remains unchanged. Move 5b and 5c to the right a certain distance to smoothly remove the tie bars. For the same structural component, after determining the optimal amount of deflection through testing, keep 5a fixed in position during subsequent tie bar use. After the tie bars are in place, tighten 5b and then 5c.

[0079] It should be noted that for horizontal tightening components, when the required anti-deformation of the ear plate is small or the rebound force after welding is small, the combination of the pressure head and the pressure head connector can be cancelled, and the connector can be used directly as the pressure head, or both can be cancelled, and only the tightening bolts are retained to tighten and anti-deform the ear plate. Similarly, no indentation will be generated on the surface. In this way, the length of the F-type main body and the tightening bolts can be shortened, reducing a certain amount of production cost.

[0080] It should be noted that, when the ear plate welding process is determined, the reverse deformation direction and reverse deformation amount of the ear plate are also determined. At this time, only one pair of force relief components is required, which can further reduce the production cost.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
