The moving seat is arranged on the top of the plate girder to enable the moving seat to move along the top of the plate girder. A group of slide rails are arranged on the two sides of the moving seat downward. The slide rail is provided with a sliding groove. The chiseling mechanism is arranged with a sliding block matched with the sliding groove to enable the chiseling mechanism to slide up and down along the slide rail. The driving mechanism is arranged matched with the chiseling mechanism to enable the driving mechanism to lift the chiseling mechanism upward along the slide rail.

Description

Technical Field

[0001] This invention relates to the technical field of slab beam roughening devices, and more specifically, to a hinge joint roughening device. Background Technology

[0002] Slab girders are used in the superstructure of bridges. Several slab girders are spliced ​​together to form the main body of the bridge deck. After several slab girders are placed in position, concrete needs to be poured between adjacent girders to connect them. To ensure a firm connection between adjacent girders, their sides need to be roughened before placement. Existing roughening equipment is generally designed in a U-shape, with a roughening mechanism on each side. When the roughening equipment is fitted onto the slab girder, the roughening mechanisms on both sides are located on either side of the girder, thus roughening both sides. Because the slab girder exerts a large reaction force on the roughening mechanism during the roughening process, and this reaction force is transmitted to both sides of the roughening equipment, the roughening equipment is generally quite robust and large. Furthermore, the roughening mechanism usually uses a rotating method, making its structure relatively complex. Summary of the Invention

[0003] The purpose of this invention is to provide a hinge seam chiseling device, in which the chiseling mechanism can strike the plate beam upon falling, and the structure is simple.

[0004] The embodiments of the present invention are achieved through the following technical solutions:

[0005] A scalloped joint roughening device includes a movable base, a slide rail, a roughening mechanism, and a drive mechanism.

The slide rails are provided with grooves. The roughening mechanism is fitted with a slider that cooperates with the grooves so that it can slide up and down along the slide rails. The drive mechanism is fitted to the roughening mechanism so that it can lift the roughening mechanism upwards along the slide rails. The lower part of the slide rails is inclined towards the plate beam so that when the roughening mechanism slides down to the bottom of the slide rails, it abuts against the side of the plate beam.

[0006] Furthermore, the driving mechanism includes a movable pulley, a pull rope, a driving component, and several fixed pulleys; one end of the pull rope is fixed to the movable seat, and the other end is connected to the chiseling mechanism; the movable seat is provided with a guide groove; the movable pulley is slidably disposed in the guide groove; the driving component is configured to cooperate with the movable pulley so that the driving component can drive the movable pulley to slide along the guide groove; the movable pulley is configured to cooperate with the pull rope so that the movement of the movable pulley can pull the chiseling mechanism through the pull rope; several fixed pulleys are configured to cooperate with the pull rope so that the fixed pulleys guide the pull rope; each chiseling mechanism is provided with a set of driving mechanisms.

[0007] Furthermore, the movable pulley is provided with a frustum-shaped pulling head; the driving component is a hydraulic cylinder; the hydraulic cylinder is provided with a connecting rod; each end of the connecting rod is fitted with a pull head and is provided with a latch; the latch includes a plurality of hooks arranged in a ring; the plurality of hooks are fitted with the pull head and hinged to the connecting rod, so that the hooks open when the pull head pushes the hooks; the hooks are provided with a return spring, so that the plurality of hooks gather under the action of the return spring; the movable seat is also fitted with an unlocking block, so that the hooks open when the hooks push the unlocking block.

[0008] Furthermore, two slide rails are provided on both sides of the movable seat; the two slide rails on the same side are distributed at both ends of the movable seat and are respectively connected to one end of the chiseling mechanism.

[0009] Furthermore, the slide rail is hinged to the movable seat; along the length of the plate beam, the two slide rails at the same end of the movable seat are connected by two screws; each of the two screws is hinged to one of the slide rails; the two screws are connected by a nut; the threads at both ends of the nut are arranged in opposite directions.

[0010] Furthermore, the chiseling mechanism includes a mounting plate, chiseling nails, and a counterweight; the mounting plate is connected to the slide rail; the chiseling nails and the counterweight are each disposed on one side of the mounting plate.

[0011] Furthermore, the chisel nail is slidably inserted through the mounting plate; a push spring is provided inside the mounting plate to cooperate with the chisel nail.

[0012] Furthermore, the movable seat is provided with a pressure-bearing wheel and a positioning wheel; the pressure-bearing wheel is disposed corresponding to the top surface of the plate beam so that the pressure-bearing wheel is placed on the top surface of the plate beam; the positioning wheel is disposed corresponding to the side surface of the plate beam so that the positioning wheel abuts against the side surface of the plate beam.

[0013] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0014] In use, the hinge seam roughening device of the present invention places the movable seat above the plate beam. At this time, the slide rails on both sides of the movable seat are downward and inclined to the side of the plate beam. The drive mechanism lifts the roughening mechanism upward and then releases it. Subsequently, the roughening mechanism falls under the action of gravity. During the fall, due to the action of the slider and the groove, the roughening mechanism slides downward along the slide rail, gradually approaching and impacting the side of the plate beam. This forms a pit on the side of the plate beam, thereby achieving the roughening effect.

[0015] This roughening device roughens the beam by impact, eliminating the need for a slide rail to apply a large thrust to the beam side and create a significant impact force. This reduces the need for an overly robust slide rail, further minimizing the overall size. Furthermore, the roughening mechanism eliminates the need for complex rotating mechanisms, simplifying the overall structure. Attached Figure Description

[0029] Example:

[0030] like Figures 1-6 As shown, the present invention provides a scabbling device for hinged seams, including a movable base 1, a slide rail 2, a scabbling mechanism 3, and a driving mechanism 4. The movable base 1 is fitted onto the top of a plate beam 5, allowing the movable base 1 to move along the top of the plate beam 5. Specifically, the movable base 1 is the foundation of the entire scabbling device, and other components are directly or indirectly mounted on it. The movable base 1 is provided with a pressure roller 13 and a positioning roller 14. The pressure roller 13 supports the entire scabbling device and is positioned corresponding to the top surface of the plate beam 5, so that the pressure roller 13 is placed on the top surface of the plate beam 5. The positioning roller 14 is positioned corresponding to the side surface of the plate beam 5, so that the positioning roller 14 abuts against the side surface of the plate beam 5. The positioning rollers 14 on both sides clamp the plate beam 5 in the middle, thereby positioning the movable base 1 and preventing the movable base 1 from sliding left and right on the plate beam 5.

[0031] A set of slide rails 2 is provided downwards on each side of the movable base 1. Each slide rail 2 has a groove 21. The groove 21 is actually an oblong hole in the slide rail 2, and its length is approximately equal to the length of the slide rail 2. A slider 31 is provided in conjunction with the groove 21 to facilitate the roughening mechanism 3. The slider 31 is actually a protruding part on the side of the roughening mechanism 3. The slider 31 is accommodated in the groove 21 and can slide along the groove 21, allowing the roughening mechanism 3 to slide up and down along the slide rail 2. A drive mechanism 4 is provided in conjunction with the roughening mechanism 3 to lift the roughening mechanism 3 upwards along the slide rail 2. The drive device can be a motor or other actuating mechanism. The lower part of the slide rail 2 is inclined towards the plate beam 5 so that when the roughening mechanism 3 slides down to the bottom of the slide rail 2, the roughening mechanism 3 abuts against the side of the plate beam 5.

[0032] When using the hinge seam roughening device of the present invention, the movable seat 1 is placed above the plate beam 5. At this time, the slide rails 2 on both sides of the movable seat 1 are lowered and tilted to the side of the plate beam 5. The drive mechanism 4 lifts the roughening mechanism 3 upward and then releases it. Subsequently, the roughening mechanism 3 falls under the action of gravity. During the falling process, due to the action of the slider 31 and the slide groove 21, the roughening mechanism 3 slides downward along the slide rail 2, and gradually approaches and impacts the side of the plate beam 5. This can form a pit on the side of the plate beam 5, thereby achieving the roughening effect.

[0033] This roughening device roughens the beam 5 through impact, eliminating the need for the slide rail 2 to apply a large thrust to the roughening mechanism 3 to achieve a significant impact on the side of the beam 5. This reduces the need for an overly robust slide rail 2, further minimizing the overall size. Simultaneously, the roughening mechanism 3 eliminates the need for complex rotating mechanisms, simplifying the overall structure.

[0034] In this embodiment, the drive mechanism 4 includes a movable pulley 41, a pull rope 42, a drive component, and several fixed pulleys 44. For example... Figure 3 As shown, one end of the pull rope 42 is fixed to the movable base 1, and the other end is connected to the chiseling mechanism 3. The movable base 1 is provided with a guide groove 11. The guide groove 11 can be configured as a dovetail groove, which is provided on the surface of the movable base 1. The movable pulley 41 is equipped with a dovetail-shaped sliding block in cooperation with the dovetail groove, so that the sliding block is slidably disposed in the guide groove 11. The pull rope 42 passes through the movable pulley 41, so that the movement of the movable pulley 41 can pull the chiseling mechanism 3 through the pull rope 42. The drive component is configured to cooperate with the movable pulley 41, so that the drive component can drive the movable pulley 41 to slide along the guide groove 11. Several fixed pulleys 44 are configured to cooperate with the pull rope 42, so that the fixed pulleys 44 guide the pull rope 42. Each chiseling mechanism 3 is provided with a set of drive mechanisms 4.

[0035] During the chiseling process, the drive component moves the movable pulley 41, which in turn moves the pull rope 42. During this process, the chiseling mechanism 3 is gradually lifted. As the pull rope 42 is pulled, several fixed pulleys 44 act as guides, ensuring the chiseling mechanism 3 rises smoothly.

[0036] In this embodiment, the movable pulley 41 is provided with a frustum-shaped pulling head 43. The driving component is a hydraulic cylinder 45. The hydraulic cylinder 45 is provided with a connecting rod 46. The connecting rod 46 is perpendicular to the telescopic rod of the hydraulic cylinder 45. Each end of the connecting rod 46 is fitted with a pull head 43 and is provided with a latch. The latch includes several hooks 47 arranged in a ring. The hooks 47 are fitted with the pulling head 43 and hinged to the connecting rod 46 so that the hooks 47 open when the pulling head 43 pushes against them. Specifically, when the hooks 47 hit the pulling head 43, since the pulling head 43 is frustum-shaped, the hooks 47 open under the guidance of the pulling head 43. The hooks 47 are provided with a return spring 48 so that the hooks 47 converge under the action of the return spring 48. In other words, after the hook 47 passes the frustum-shaped pull head 43, the hook 47 can be reset by the action of the return spring 48, and then engage with the pull head 43, as shown. Figure 4 As shown. The movable seat 1 is also equipped with an unlocking block 12 in conjunction with the hook 47. The unlocking block 12 is shaped like an inclined plane, and its interaction with the hook 47 allows the hook 47 to open, as shown. Figure 5 As shown.

[0037] When the pulling head 43 is not under the pulling force of the hydraulic cylinder 45, it moves to one end of the moving seat 1 under the gravity of the chiseling mechanism 3. When the hydraulic cylinder 45 moves toward the pulling head 43 and pushes it, several hooks 47 open and gradually hold the pulling head 43, finally tightening it under the action of the return spring 48, thus connecting the hooks 47 and the pulling head 43. At this time, pulling the hydraulic cylinder 45 will cause the hooks 47 to move the pulling head 43, thereby causing the chiseling mechanism 3 to gradually rise. When the chiseling mechanism 3 is raised to its position, the hooks 47 continue to be pulled, causing the unlocking block 12 to push the hooks 47, thus opening the hooks 47. At this time, the pulling head 43 disengages from the hooks 47, and the chiseling mechanism 3 falls and impacts the side of the plate beam 5 under the action of gravity. Clearly, by making the position of the unlocking block 12 adjustable, the lifting height of the chiseling mechanism 3 can be adjusted, thereby adjusting the chiseling force. Specifically, several screw holes can be provided on the surface of the movable base 1, and the unlocking block 12 can be fixed to the screw holes on the surface of the movable base 1 with screws. The positions of the screw holes correspond to different chiseling forces.

[0038] In this embodiment, two slide rails 2 are provided on both sides of the movable base 1. The two slide rails 2 on the same side are distributed at both ends of the movable base 1 and are respectively connected to one end of the chiseling mechanism 3. This allows the chiseling mechanism 3 to be guided by the two slide rails 2, making the lifting and lowering of the chiseling mechanism 3 more stable. At the same time, each chiseling mechanism 3 can also be provided with two pull ropes 42, and both pull ropes 42 are connected to the corresponding movable pulleys 41. The two pull ropes 42 are respectively connected to both ends of the chiseling mechanism 3, thereby making the forces on both ends of the chiseling mechanism 3 more balanced and thus more stable.

[0039] The slide rail 2 is hinged to the movable seat 1. Along the length of the plate beam 5, two slide rails 2 at the same end of the movable seat 1 are connected by two screws 6. Each screw 6 is hinged to one slide rail 2. The two screws 6 are connected by a nut 7. The threads at both ends of the nut 7 are opposite. By rotating the nut 7, the angle between the two slide rails 2 changes, which in turn changes the angle between the lower end of the two slide rails 2 and the side of the plate beam 5. Ultimately, this changes the contact point between the chiseling mechanism 3 and the side of the plate beam 5. In other words, the chiseling position can be adjusted by rotating the nut 7. In addition, during the downward sliding of the chiseling mechanism 3, the slide rail 2 is actually subjected to a horizontal component of the force from the chiseling mechanism 3. This component of the force is directed outward. Based on the connection relationship of the two slide rails 2, it can be concluded that the two slide rails 2 simultaneously press against the screws 6, which causes the lower part of the two slide rails 2 to tend to move closer to the plate beam 5. Since the two chiseling mechanisms 3 are driven by the same hydraulic cylinder 45, their actions are synchronized. This ensures that the force applied by the two slide rails 2 to the screws 6 is the same, preventing the slide rails 2 from shaking.

[0040] In this embodiment, the chiseling mechanism 3 includes a mounting plate 32, chiseling nails 33, and a counterweight 34. The mounting plate 32 is connected to the slide rail 2. The chiseling nails 33 and the counterweight 34 are each disposed on one side of the mounting plate 32. Several chiseling nails 33 are provided, so that when the chiseling mechanism 3 impacts the plate beam 5, it can generate several indentations on the plate beam 5. The counterweight 34 is used to increase the weight of the chiseling mechanism 3, thereby ensuring that the impact can generate sufficient impact force. In order to ensure that several chiseling nails 33 contact the plate beam 5 at the same time, the slider 31 is configured to be quadrilateral, so that the slider 31 can only slide between the box gauge and the slide groove 21 and cannot rotate. When the angle of the chiseling mechanism 3 is properly adjusted, it will not rotate, thereby ensuring that the surface where several chiseling nails 33 are located is almost parallel to the surface where the chiseling position is located.

[0041] In this embodiment, the chisel nails 33 are slidably inserted into the mounting plate 32. A push spring 35 is provided inside the mounting plate 32 to cooperate with the chisel nails 33. In practice, it is difficult for several chisel nails 33 to simultaneously impact the plate beam 5. When some chisel nails 33 impact the plate beam 5, their corresponding push springs 35 are compressed, causing the remaining chisel nails 33 to gradually contact the plate beam 5. This ensures that all chisel nails 33 can contact the plate beam 5, thereby guaranteeing the chiseling effect.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
