Description

Technical Field

[0001] The invention relates to the technical field of metal parts repairing equipment, in particular to a metal tooth plate reshaping equipment. Background Art

[0002] The rotary screen garbage cleaning machine is a hydraulic equipment used to intercept aquatic plants and debris in the river. The screen plate in the rotary screen garbage cleaning machine is the main component used to intercept river debris. A tooth rake is installed on the outside of the screen plate. The tooth rake consists of a horizontal support tube (round tube or square tube) and two rows of tooth plates welded on the horizontal support tube. The tooth plates arranged in the vertical direction pass through the gaps in the screen plate to lift the intercepted debris. The tooth plates arranged in the horizontal direction are located on the outside of the screen plate to provide side support for the intercepted debris. The tooth rake rotates cyclically driven by the motor and chain to hook and lift the debris on the screen plate.

[0003] The debris intercepted by the grille plate includes not only light objects such as water plants, but also hard objects such as stones, such as stones carried by excessive water flow during flood discharge. During the lifting process of the tooth rake, large-sized hard objects will bump or hit the horizontally arranged tooth plates, causing them to deform. Small-sized hard objects stuck in the gaps between the grille plates will interfere with the vertically arranged tooth plates, causing them to deform. Therefore, during the maintenance process, the two rows of tooth plates on the tooth rake need to be calibrated to restore them to their original state.

[0004] In the prior art, when the tooth plate is reshaped, the conventional crowbar cannot play its advantages due to the lack of a fulcrum, so small tools such as needle-nosed pliers are often used. However, the torque of needle-nosed pliers is small. In an environment with a large amount of reshaping, the efficiency is low and the tools are easily worn out. The maintenance work before the flood season is time-sensitive and the task is heavy. It is urgent to design a device that can quickly realize the restoration of the tooth plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The metal tooth plate reshaping device disclosed in the present invention can clamp and position the tooth rake of the grille cleaning machine, provide a stable support for the reshaping plate, and facilitate the reshaping of the tooth plate by the reshaping plate, specifically:

[0016] In the clamping mechanism, two X-axis clamps clamp the horizontal support tube on the tooth rake from the side, and two Z-axis clamps clamp the horizontal support tube on the tooth rake from the bottom, so that the device and the horizontal support tube are firmly positioned; the driving structure design of the X-axis clamp and the Z-axis clamp share a set, and the driving process is divided into two stages, the first stage is to drive the two X-axis clamps to approach each other, and the second stage is to drive the two Z-axis clamps to lift up at the same time, so that the X-axis clamp and the Z-axis clamp are clamped on the horizontal support tube in one driving process, and the design concept is novel and the structural design is reasonable;

[0017] After the clamping and positioning is completed, the position of the compound plate is adjusted through the self-locking adjustment component to make it move accurately to the side of the deformed tooth plate, and the swing arm is pushed to rotate with the cylinder as the center. The compound plate is used to apply force to the tooth plate to restore the metal tooth plate to its original state; in the self-locking adjustment component, when the winding drum rotates synchronously with the self-locking adjustment screw, the locking state of the swing arm and the slide plate can be released. When the threaded transmission of the winding drum and the self-locking adjustment screw is realized, the sliding seat and the slide plate are pushed to move, thereby adjusting the relative position of the compound plate and the swing arm. After the adjustment is completed, the handle is released, and the locking column locks the position of the swing arm and the slide plate again. This structural design optimizes the personnel operation process through structural improvements.

[0018] Since the deformation of the tooth plates is regionalized, that is, multiple tooth plates in an area in the same row show different degrees of bending due to impact, when the equipment disclosed in the present invention is in use, maintenance personnel can quickly adjust the position of the reshaping plate to perform multi-point reshaping operations on multiple tooth plates in the same row, thereby effectively improving the efficiency of maintenance operations.

[0019] In summary, the reshaping device disclosed in the present invention can clamp the horizontal support tube of the tooth rake from the X-axis and Z-axis directions, so that the reshaping device and the tooth rake are firmly connected, ensuring that the application position of the reshaping force is more accurate and improving the reshaping quality of the tooth plate.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 , this embodiment provides a metal tooth plate reshaping device, including a clamping mechanism and a reshaping mechanism.

[0031] The clamping mechanism includes a cylinder 101 , a clamping drive assembly and a clamping assembly. A limit ring 102 and a rotating ring 103 are arranged outside the cylinder 101 . Two limit rings 102 are fixedly arranged on the cylinder 101 , and the rotating ring 103 is located between the two limit rings 102 .

[0032] The clamping drive assembly includes a driving hand wheel 104, a clamping drive rod 105, an internally threaded tube 106, a driving disk 107, and a guide column 108. The driving hand wheel 104 is located outside the cylinder 101. The clamping drive rod 105 is arranged on the axis of the driving hand wheel 104. The end of the clamping drive rod 105 away from the driving hand wheel 104 extends into the cylinder 101. The clamping drive rod 105 is rotatably connected to the cylinder 101. The portion of the clamping drive rod 105 located in the cylinder 101 is provided with a first slide bar 111. The first slide bar 111 and the axis of the clamping drive rod 105 are parallel to each other. The internally threaded tube 106 is slidably connected in the cylinder 101. A second slide bar is arranged on the inner wall of the cylinder 101. The extension direction of the second slide bar is parallel to the extension direction of the cylinder 101. The axes are parallel to each other, the outer side of the internally threaded tube 106 is provided with a second slide groove adapted to the second slide bar, the outer edge of the driving disk 107 is provided with an external thread matched with the thread of the internally threaded tube 106, the center of the driving disk 107 is provided with a center hole plug-matched with the clamping driving rod 105 and a first slide groove slidably matched with the first slide bar 111, and the end surface of the driving disk 107 away from the clamping driving rod 105 is provided with a round table 112, the center hole and the first slide groove both pass through the driving disk 107 and the round table 112, an adapter plate 113 is rotatably provided on the outer side of the round table 112, and two first strip holes 114 are provided on the adapter plate 113, the guide column 108 is fixed in the cylinder 101, and the axis of the guide column 108 is perpendicular to the axis of the cylinder 101.

[0033] The clamping assembly includes an X-axis clamping plate 109 and a Z-axis clamping plate 110. There are two X-axis clamping plates 109. The upper end of the X-axis clamping plate 109 is conical. The upper end of the X-axis clamping plate 109 extends into the internal threaded tube 106. The two X-axis clamping plates 109 are slidably arranged on the guide column 108. The X-axis clamping plate 109 is provided with a second slide groove 115. The extension direction of the second slide groove 115 is parallel to the axis of the cylinder 101. There are two Z-axis clamping plates 110. The Z-axis clamping plates 110 are respectively slidably connected to the second slide grooves. 115, a second strip hole 116 is set on the Z-axis clamping plate 110, and the extension direction of the second strip hole 116 is parallel to the axis of the cylinder 101. The guide column 108 is located in the second strip hole 116. A lifting drive rod 117 is set at the upper end of the Z-axis clamping plate 110. The upper end of the lifting drive rod 117 passes through the X-axis clamping plate 109 and then slides with the first strip hole 114. The lifting drive rod 117 is slidably connected to the X-axis clamping plate 109, and an inner bending plate 118 is set at the lower end of the Z-axis clamping plate 110.

[0034] When the clamping drive rod 105 drives the driving disk 107 to rotate circumferentially, the adapter plate 113 and the driving disk 107 rotate relative to each other, the adapter plate 113 is in a stationary state, and the axial position of the lifting drive rod 117 connected to the adapter plate 113 does not move. Under the thread cooperation between the driving disk 107 and the internal threaded tube 106, and under the limiting action of the second slide bar and the second slide groove, the internal threaded tube 106 only moves downward along its axis, and the internal threaded tube 106 squeezes the conical surfaces at the upper ends of the two X-axis clamping plates 109 at the same time. Under the guiding action of the guide column 108, the two X-axis clamping plates 109 approach each other radially. At this time, the two Z-axis clamping plates 110 also approach each other synchronously. , the upper end of the lifting driving rod 117 slides in the first strip hole 114 on the adapter plate 113, providing guidance for the upper ends of the two X-axis clamps 109, and the two lifting driving rods 117 also approach each other; when the two X-axis clamps 109 clamp the horizontal support tube on the tooth rake, the downward movement of the internal threaded tube 106 is stopped by the two X-axis clamps 109, and the internal threaded tube 106 cannot rotate in the circumferential direction under the limiting action of the second slide bar and the second slide groove, so that after the continuous rotation of the clamping driving rod 105, the driving disk 107 and the internal threaded tube 106 are threadedly matched, and the driving disk 107 moves upward, and the Z-axis clamp 110 is driven to move upward through the lifting driving rod 117. In this way, the X-axis clamp 109 and the Z-axis clamp 110 clamp the horizontal support tube on the tooth rake. It should be pointed out that the driving hand wheel 104 can be replaced by a hand drill, the upper end of the clamping driving rod 105 adopts an external hexagonal design, and the hand drill is equipped with an internal hexagonal socket to drive the clamping driving rod 105.

[0035] As a preferred solution of this embodiment, the clamping mechanism also includes a first return spring 119 sleeved on the outside of the clamping drive rod 105, and the two ends of the first return spring 119 are respectively connected to the upper end surface of the drive disk 107 and the circular ring fixedly connected to the outside of the clamping drive rod 105. The first return spring 119 rotates with the clamping drive rod 105 and the drive disk 107. The first return spring 119 is always in a compressed state. The thrust of the first return spring 119 is used to provide resistance for the upward movement of the drive disk 107, so that when the clamping drive rod 105 rotates, the internal threaded tube 106 is preferentially driven to move downward. When the internal threaded tube 106 stops moving downward, the continued rotation of the clamping drive rod 105 will overcome the elastic force of the first return spring 119, and the drive disk 107 is moved upward along the clamping drive rod through the threaded connection between the internal threaded tube 106 and the drive disk 107.

[0036] As a preferred solution of this embodiment, a third return spring 120 is sleeved on the outer side of the guide column 108, and the two ends of the third return spring 120 are respectively against the two X-axis clamps 109. After the restoration is completed, the third return spring 120 can open the two X-axis clamps 109. It should be pointed out that: the elastic force of the third return spring 120 is smaller than the elastic force of the first return spring 119.

[0037] The compound mechanism includes a swing arm 201, a slide plate 202, a compound plate 203 and a self-locking adjustment component. One end of the swing arm 201 is fixedly connected to the rotating ring 103. The swing arm 201 is provided with a hollow inner cavity. A first positioning hole 204 is provided on the side of the swing arm 201. A third strip hole is provided on the lower end surface of the swing arm 201. The third strip hole is connected to the hollow inner cavity. The slide plate 202 is slidably arranged on the outside of the swing arm 201. A second positioning hole corresponding to the first positioning hole 204 is provided on the slide plate 202. The compound plate 203 is fixedly connected to the lower end of the slide plate 202. Both sides of the compound plate 203 are fixedly connected to the slide plate 202.

[0038] The self-locking adjustment component includes a handle 205, a self-locking adjustment screw 206, a sliding seat 207, a winding drum 208, a winding rope 209 and a locking plug 210. The handle 205 is located at the end of the swing arm 201 away from the rotating ring 103, and the handle 205 is fixedly connected to the self-locking adjustment screw 206, and the self-locking adjustment screw 206 is rotatably connected in the swing arm 201; the sliding seat 207 is sleeved on the outside of the self-locking adjustment screw 206, and the sliding seat 207 is slidably fitted in the hollow inner cavity of the swing arm 201. The upper end of the complex plate 203 passes through the third strip hole and is fixedly connected to the lower end surface of the sliding seat 207. The winding drum 208 is threadedly connected to the outside of the self-locking adjustment screw 206, and the winding drum 208 is located in the sliding seat 207. Two assembly seats 211 are arranged in the winding drum 208, and the two assembly seats 211 are located on the diagonal line of the winding drum 208. The winding rope 209 is two ropes wound around the outside of the winding drum 208. The locking pin 210 is slidably connected in the assembly seat 211. One end of the locking pin 210 passes through the sliding seat 207 and is inserted into the second positioning hole and the first positioning hole 204 in sequence. A second return spring 212 is arranged between the other end of the locking pin 210 and the bottom of the assembly seat 211. The second return spring 212 is always in a compressed state. One end of the winding rope 209 is fixedly connected to the winding drum 208, and the other end passes through the assembly seat 211 and is fixedly connected to the locking pin 210. The second return spring 212 is located on the outside of the winding rope 209.

[0039] In the initial state, the second return spring 212 is in a compressed state, pushing the locking pin 210 outward, and the locking pin 210 extends into the first positioning hole 204 and the second positioning hole, and the self-locking adjustment screw 206 is rotated. The winding drum 208 rotates synchronously with the self-locking adjustment screw 206, and the winding rope 209 is wound on the outside of the winding drum 208. The winding rope 209 pulls the locking pin 210 out of the first positioning hole 204, and the second return spring 212 is further compressed. When the locking pin 210 leaves the first positioning hole 204, the slide plate 202 cancels the lock, and the assembly seat limits the position of the locking pin 210, so that the winding drum 208 stops rotating circumferentially.

[0040] When the self-locking adjustment screw 206 continues to rotate, the winding drum 208 cooperates with the threaded transmission of the self-locking adjustment screw 206, and the winding drum 208 moves axially. When the winding drum 208 contacts the inner wall of the sliding seat 207, the winding drum 208 pushes the sliding seat 207 and the slide plate 202 to move, thereby adjusting the relative position of the compound plate 203 and the swing arm 201. After the adjustment is completed, the handle 205 is released, and under the elastic force of the second return spring 212, the winding rope 209 is pulled to be wound around the outside of the winding drum 208, driving the winding drum 208 to rotate in the opposite direction, so that the locking column is plugged into the first positioning hole 204 and the second positioning hole, the position of the slide plate 202 is locked, and the position of the compound plate 203 and the swing arm 201 is fixed.

[0041] The working principle of the metal tooth plate reshaping device provided by the present invention is as follows:

[0042] Equipment positioning: The driving hand wheel 104 drives the clamping driving rod 105 to rotate. At this time, under the elastic force of the first return spring 119, the driving disk 107 is restricted from moving upward. The first slide bar 111 cooperates with the first slide groove to make the clamping driving rod 105 and the driving disk 107 rotate synchronously. Therefore, when the clamping driving rod 105 rotates, the driving disk 107 cooperates with the thread transmission of the internal threaded tube 106 to make the internal threaded tube 106 move downward. The internal threaded tube 106 moving downward is pressed against the two X The conical arc surface at the upper end of the axis clamping plate 109 exerts a force to make the two X-axis clamping plates 109 approach each other until the two X-axis clamping plates 109 clamp the horizontal support tube of the tooth rake from the side. At this time, the distance between the two X-axis clamping plates 109 is a constant value, and the downward movement of the internal threaded tube 106 is stopped by the two X-axis clamping plates 109. The driving plate 107 moves upward, driving the Z-axis clamping plate 110 to move upward, and the inner bending plate 118 on the Z-axis clamping plate 110 clamps the horizontal support tube of the tooth rake from the bottom. Thus, the metal tooth plate reshaping equipment and the tooth rake are firmly clamped and positioned.

[0043] Tooth plate restoration: rotate the self-locking adjustment screw 206. At this time, the rotation of the take-up drum 208 is not restricted. The self-locking adjustment screw 206 drives the take-up drum 208 to rotate, and the take-up rope 209 is wound on the outside of the take-up drum 208. The locking plug 210 is pulled inward, and the second return spring 212 is further compressed. When the locking plug 210 leaves the first positioning hole 204, the slide plate 202 can slide freely on the outside of the swing arm. At this time, the circumferential rotation of the take-up drum 208 is restricted. When the self-locking adjustment screw 206 continues to be rotated, the self-locking adjustment screw 206 and the take-up drum 208 are threadedly transmitted, thereby driving the take-up drum 208 to move left and right. When the take-up drum 208 After contacting the inner wall of the sliding seat 207, the winding drum 208 pushes the sliding seat 207 and the slide plate 202 to move left and right, and the slide plate 202 drives the compound plate 203 to move to the bent tooth plate position, and the handle 205 is released. Under the elastic force of the second reset spring 212, the winding rope 209 is pulled to be wound around the outside of the winding drum 208, driving the winding drum 208 to rotate in the opposite direction, so that the locking column 210 is plugged into the first positioning hole 204, and the position of the slide plate 202 and the compound plate 203 is locked. Then the maintenance personnel pushes the swing arm 201 to rotate around the cylinder 101, and applies a force to the tooth plate through the compound plate 203 to restore the tooth plate to its original state.

[0044] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
