Description

Technical Field

[0001] The invention belongs to the technical field of concrete, in particular to a device for vibrating concrete inside an arch rib of an arch bridge. Background Art

[0002] The arch rib of an arch bridge is the core load-bearing component of the arch bridge. It mainly bears axial pressure and may also bear bending moment and shear force. Its performance directly affects the safety and durability of the bridge. It is an arc-shaped load-bearing component set along the span direction of the arch bridge. It is usually made of concrete, steel or composite materials. The cross-section forms are various, such as rectangular, box-shaped, I-shaped, circular, etc. There are mainly three types of concrete arch ribs, steel arch ribs and composite arch ribs.

[0003] The vibrating device for the concrete inside the arch rib of an arch bridge is a key equipment used to ensure the dense formation of the arch rib concrete. Its selection needs to be determined comprehensively based on the arch rib structure, cross-sectional dimensions, steel density and construction technology. Common vibrating devices include inserted vibrating rods and attached vibrators.

[0004] In the current existing technology, when an inserted vibrating rod is used to vibrate the arch rib, the vibrating rod is usually manually supported by the operator. Since the vibrating rod has a certain reverse vibration force during vibration, it is very easy to make the operator feel tired, and the labor consumption intensity is relatively high. In addition, since the construction position of the arch rib is relatively high, there are certain safety hazards to the personal safety of the operator when the operator holds the vibrating rod to vibrate it.

[0005] To this end, the present invention provides a device for vibrating concrete inside the arch rib of an arch bridge. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a device for vibrating concrete inside the arch rib of an arch bridge described in the present invention comprises a support plate, a hydraulic cylinder is fixedly installed at the middle position of the bottom of the support plate, an axis box is fixedly installed at the output end of the hydraulic cylinder, a vibrating rod is arranged inside the axis box, the vibrating rod consists of three parts: a vibrating head, a soft shaft and a motor, a positioning assembly is provided on the inner wall of the axis box, the positioning assembly is used to drive the vibrating rod and the axis box to connect, vertical rods are symmetrically fixedly installed at the bottom of the hydraulic cylinder, a knocking box is fixedly installed between two of the four vertical rods, a knocking assembly is provided inside the knocking box, the knocking assembly is used to knock the outer wall of the arch rib, connecting rods are provided at the bottoms of the four vertical rods, and mounting assemblies are provided on the outer walls of the four connecting rods and the vertical rods, the mounting assembly comprises a connecting block, and the mounting assembly is used to drive the connecting block to install and connect the device with the arch rib;

[0008] By inserting the vibrating rod into the arch rib through the vibrating port on the arch rib, and then connecting one end of the arch rib to the shaft box through the clamping assembly in the shaft box, when the vibrating rod is connected to the shaft box, the four connecting rods and the installation assembly on the vertical rod are used to drive the connecting block to install and connect the device to the arch rib. When the device and the arch rib are installed, the vibrating rod will be fixed on the top of the arch rib, so that the operator does not need to manually support the vibrating rod, which reduces the operator's consumption and ensures the operator's personal safety. When the concrete arch rib needs to be vibrated, the drive motor is turned on. The vibrating head is driven by the flexible shaft to operate, and the vibrating rod can realize the vibration operation of the arch rib. During the vibration, the hydraulic cylinder drives the vibrating rod to move up and down, so that the vibrating rod moves and vibrates on the inner wall of the arch rib. Compared with vibrating at a point of the arch rib, the moving vibration can increase the vibration area and better vibrate the concrete in the arch rib. While the vibrating rod is vibrating, the knocking assembly in the knocking box knocks on the outer wall of the arch rib, thereby vibrating the concrete in the arch rib, accelerating the divergence of bubbles in the concrete, and assisting the vibrating rod to vibrate the concrete, thereby accelerating the vibration operation of the concrete.

[0009] Preferably, the positioning assembly includes a retaining block, and there are multiple retaining blocks, the tops of the multiple retaining blocks are all provided with an inclined sliding surface and the inner sides of the multiple retaining blocks are arc surfaces, the outer walls of the multiple retaining blocks are all slidably connected to the inner wall of the shaft box, and a return spring is provided between one side of the multiple retaining blocks and the inner wall of the shaft box. A fixing plate is fixedly installed on the top of the vibrating rod, and the inner sides of the multiple retaining blocks can be fixedly fitted with the outer wall of the fixing plate. When the vibrating rod and the shaft box are connected, one end of the fixing plate is inserted into the shaft box. The top of the fixing plate will push multiple retaining blocks to squeeze the reset spring and move backward. When the top of the fixing plate contacts the top of the inner wall of the shaft box, it stops pushing the fixing plate to move. At this time, multiple retaining blocks will clamp and fix the fixing plate under the elastic push of the reset spring, thereby realizing the connection between the vibrating rod and the shaft box, and playing the role of fixing and installing the vibrating rod. By pushing multiple retaining blocks to clamp and fix the fixing plate through multiple reset springs, the device can fix and install vibrating rods of various sizes.

[0010] Preferably, a plurality of limit plates are symmetrically fixedly installed on the inner wall of the shaft box, and the outer walls of the plurality of retaining blocks are slidably connected to the inner walls of the plurality of limit plates respectively. When the retaining block is pushed backward by the fixing plate, the retaining block will move backward between the two limit plates. When the top of the fixing plate contacts the inner wall of the vibrating rod, the plurality of retaining blocks will retain the fixing plate under the elastic push of the reset spring. The setting of the limit plate plays a role in limiting the sliding of the retaining block, preventing the retaining block from dislocating due to lack of restriction when the retaining block slides backward in the shaft box.

[0011] Preferably, the installation component also includes an arc-shaped push block, and a vibration-damping spring is symmetrically arranged between the bottom of the arc-shaped push block and the inner wall of the connecting block. The outer wall of the arc-shaped push block can be slidably connected to the inner wall of the connecting block. When it is necessary to connect and install the device to the arch rib, the four connecting rods and the multiple connecting blocks on the vertical rod are pushed toward the arch rib. When the arch rib contacts the connecting block, the connecting block is continued to be pushed to move, and the arch rib will push the arc-shaped push block to squeeze the vibration-damping spring to slide in the connecting block. When the arc-shaped push block is completely restricted by the arch rib and enters the connecting block When the arch rib is vibrated, the arch rib itself may vibrate to a certain extent. Through the setting of the vibration-damping spring, when the arch rib itself vibrates, the vibration-damping spring can unload part of the force generated by the vibration, thereby reducing the impact of the vibration generated by the arch rib itself during vibration on the connection and retention between the arch rib and the connecting block, thereby preventing the device from loosening and falling off when the arch rib is installed and connected.

[0012] Preferably, a soft pad is fixedly installed on the top of the arc-shaped push block. When the arc-shaped push block moves upward, the arc-shaped push block will drive the soft pad to move upward. When the two come into contact, the arch rib will push the arc-shaped push block downward through the soft pad, so that the connecting block clamps the arch rib and fixes it in place, thereby realizing the installation operation between the device and the arch rib. Through the provision of the soft pad, on the one hand, contact between the arch rib and the arc-shaped push block can be avoided, and it can be ensured that when the two are connected, there will be no scratches between the two due to extrusion, thereby ensuring the overall aesthetics. On the other hand, the soft pad can also slow down the vibration generated by the arch rib itself, reduce the transmission of vibration, and cooperate with the vibration-damping spring to better damp the vibration generated by the arch rib itself, thereby ensuring the stability of the fixed connection between the arc-shaped push block and the arch rib.

[0013] The top of the four connecting rods is rotatably connected to the bottom of the four vertical rods. When the device needs to be connected to the arch rib, multiple connecting blocks located on the outer walls of the vertical rods are placed on the top of the arch rib and then the connecting rods are rotated. When the multiple connecting rods are rotated in sequence, the connecting blocks located on one side thereof are rotated to the bottom of the arch rib. At this time, the connecting rods are stopped and the multiple connecting blocks are pushed to move, so that the installation connection between the arch rib and the device can be achieved. The rotatable connection between the connecting rods and the vertical rods makes it easier to find the installation position between the device and the arch rib when performing the connection operation, which is convenient for installation and disassembly.

[0014] Preferably, an inner screw shaft is symmetrically fixedly installed on the inner wall of the trough box, and a bolt is threadedly connected to the inner wall of the inner screw shaft. The top of the two bolts can be rotatably connected to the bottom of the connecting block. When the connecting rod is rotated to drive the connecting block located on one side thereof to rotate under the arch rib, the bolt is rotated by twisting the bolt. When the bolt rotates, the bolt will move upward through thread transmission in the inner screw shaft, and the bolt will push the connecting block to move in the trough box, thereby providing power for the moving contact between the connecting block and the arch rib, and playing a role in pushing the connecting block to move. By pushing the connecting block on the connecting rod to move upward, multiple connecting blocks symmetrically above and below will move relatively to each other and come closer to contact the arch rib, thereby achieving clamping and fixing of the arch rib.

[0015] The lockhole that is formed on the two ends of the hinge part is formed on the upper surface of the two end windows, and the lockhole engages with the upper surface of the two end windows in an orderly manner.

[0016] Preferably, the knocking assembly includes a knocking block, a rectangular plate is fixedly installed on the inner wall of the knocking box, the outer wall of the knocking block is slidably connected to the inner wall of the knocking box and the rectangular plate, a plurality of return springs are symmetrically arranged between one side of the knocking block and one side of the rectangular plate, a shift plate is fixedly installed on one end of the knocking block, the outer wall of the shift plate is slidably connected to the inner wall of the knocking box, and a slot block is fixedly installed on one side of the shift plate. When the vibrating rod is driven to vibrate in the arch rib, the slot block is pushed to move, and the slot block will push the knocking block through the shift plate to pull the return spring to move, and the knocking block will knock on the outer wall of the arch rib, thereby knocking on the concrete in the arch rib, accelerating the divergence of bubbles in the concrete, and at the same time, it can also cooperate with the vibrating rod to vibrate the concrete in the arch rib.

[0017] Preferably, a pressure rod is fixedly installed on the outer wall of the shaft box, and the outer wall of the pressure rod is slidably connected to the inner wall of the knocking box. A plurality of tooth blocks are fixedly installed on the outer wall of the pressure rod, and one end of the plurality of tooth blocks is symmetrically opened as an inclined sliding surface. The outer walls of the plurality of tooth blocks can be slidably connected to the inner wall of the groove block. When the connection between this device and the arch rib is completed, the vibrating rod is driven to vibrate inside the arch rib. During the vibrating, the hydraulic cylinder drives the vibrating rod to move and vibrate inside the arch rib through the shaft box. When the shaft box moves downward, the shaft box will drive the pressure rod to move downward, and the pressure rod will push the groove block through the tooth block, so that the groove block drives the slapping block to slap the outer wall of the arch rib. Through the setting of multiple tooth blocks and return block springs, when the pressure rod moves downward, the gap tapping operation of the arch rib can be realized, which is more conducive to cooperating with the vibrating rod to vibrate the concrete.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention relates to a device for vibrating concrete inside the arch rib of an arch bridge. When the connecting block is in contact with the arch rib, the arch rib will push the arc-shaped push block to squeeze the vibration-damping spring to slide. When the arc-shaped push block completely enters the connecting block, multiple connecting blocks will clamp and connect the arch rib through the arc-shaped push block, thereby realizing the connection operation between the device and the arch rib, and the arch rib itself will vibrate to a certain extent. Through the setting of the vibration-damping spring, when the arch rib itself vibrates, the vibration-damping spring can unload part of the force generated by the vibration, thereby reducing the influence of the vibration generated by the arch rib itself during vibration on the connection and retention between the arch rib and the connecting block.

[0020] 2. The device for vibrating concrete inside the arch rib of an arch bridge described in the present invention can, through the provision of a soft pad, avoid contact between the arch rib and the arc-shaped push block, and ensure that no scratches will appear between the two due to extrusion when they are connected, thereby ensuring the overall aesthetics. On the other hand, the soft pad can also slow down the vibration generated by the arch rib itself, reduce the transmission of vibration, and cooperate with the vibration-damping spring to better damp the vibration generated by the arch rib itself, thereby ensuring the stability of the fixed connection between the arc-shaped push block and the arch rib.

[0021] 3. The present invention relates to a device for vibrating concrete inside the arch rib of an arch bridge. By rotating a plurality of connecting rods in sequence to drive a connecting block located on one side thereof to rotate to the position directly below the arch rib, the connecting rods are stopped from rotating, and the plurality of connecting blocks are then pushed to move, thereby realizing the installation connection between the arch rib and the device. By performing a rotational connection between the connecting rods and the vertical rods, the device and the arch rib can better find the installation position between the two during the connection operation, which is convenient for installation and disassembly.

[0022] 4. The present invention describes a device for vibrating concrete inside the arch rib of an arch bridge. When the two connecting rods are pushed to rotate relative to each other, the outer wall of the square block will slide into the inner wall of the interlocking block through rotation. When the outer wall of the square block contacts the outer wall of the trough box, the two connecting rods will be in the same horizontal position. Subsequently, the positioning pin will be inserted into the circular hole between the two to achieve the connection operation between the two connecting rods. This ensures that the centers of the upper and lower connecting blocks are in the same straight line when the connecting block moves upward. At the same time, when the device is connected to the arch rib, the connection between the two can be reinforced for the second time, thereby strengthening the connection.

[0023] 5. The present invention relates to a device for vibrating concrete inside the arch rib of an arch bridge. It drives a hydraulic cylinder to drive a vibrating rod through an axis box to move and vibrate inside the arch rib. When the axis box moves downward, the axis box will drive the pressure rod to move downward, and the pressure rod will push the slot block through the tooth block, so that the slot block drives the slapping block to tap the outer wall of the arch rib. Through the arrangement of multiple tooth blocks and return block springs, when the pressure rod moves downward, the gap tapping operation of the arch rib can be realized, which is more conducive to the vibration operation of the concrete with the vibrating rod.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] like Figures 1 to 9 As shown, an internal concrete vibrating device for the arch rib of an arch bridge described in an embodiment of the present invention includes a support plate 1, a hydraulic cylinder 6 is fixedly installed at the middle position of the bottom of the support plate 1, an axis box 8 is fixedly installed at the output end of the hydraulic cylinder 6, a vibrating rod 5 is arranged inside the axis box 8, and the vibrating rod 5 consists of three parts: a vibrating head, a soft shaft and a motor. A positioning assembly is provided on the inner wall of the axis box 8, and the positioning assembly is used to drive the vibrating rod 5 and the axis box 8 to connect. Vertical rods 3 are symmetrically fixedly installed at the bottom of the hydraulic cylinder 6, and a knocking box 2 is fixedly installed between each of the four vertical rods 3. A knocking assembly is provided inside the knocking box 2, and the knocking assembly is used to knock on the outer wall of the arch rib. Connecting rods 4 are provided at the bottoms of the four vertical rods 3, and mounting components are provided on the outer walls of the four connecting rods 4 and the vertical rods 3. The mounting assembly includes a connecting block 7, and the mounting assembly is used to drive the connecting block 7 to install and connect the device with the arch rib;

[0037] Since the vibrating rod has a certain reverse vibration force during vibration, it is easy to make the workers feel tired and the labor consumption is high. In addition, since the construction position of the arch rib is high, there are certain safety hazards to the workers' personal safety when they vibrate with the vibrating rod.

[0038] Before operation, insert the vibrating rod 5 into the arch rib through the vibrating port on the arch rib, and then connect one end of the arch rib to the axis box 8 through the positioning assembly in the axis box 8. When the connection between the vibrating rod 5 and the axis box 8 is completed, the four connecting rods 4 and the installation assembly on the vertical rod 3 are used to drive the connecting block 7 to install and connect the device to the arch rib. When the installation of the device and the arch rib is completed, the vibrating rod 5 will be fixed at the top of the arch rib, so that the operator does not need to manually support the vibrating rod 5, which reduces the operator's consumption and ensures the operator's personal safety. When it is necessary to vibrate the concrete arch rib, drive The motor drives the vibrating head through the flexible shaft to operate, and the vibrating rod 5 can realize the vibrating operation of the arch rib. During the vibrating, the hydraulic cylinder 6 drives the vibrating rod 5 to move up and down, so that the vibrating rod 5 moves and vibrates on the inner wall of the arch rib. Compared with vibrating at a point of the arch rib, the moving vibration can increase the vibration area and better vibrate the concrete in the arch rib. While the vibrating rod 5 is vibrating, the knocking assembly in the knocking box 2 knocks on the outer wall of the arch rib, thereby beating and vibrating the concrete in the arch rib, accelerating the divergence of bubbles in the concrete, and assisting the vibrating rod 5 to vibrate the concrete, thereby accelerating the vibration operation of the concrete.

[0039] like Figures 8 and 9 As shown, the locking assembly includes a retaining block 801, and there are multiple retaining blocks 801. The tops of the multiple retaining blocks 801 are all provided with an inclined sliding surface, and the inner sides of the multiple retaining blocks 801 are arcuate surfaces. The outer walls of the multiple retaining blocks 801 are all slidably connected to the inner wall of the shaft box 8. A return spring 802 is provided between one side of the multiple retaining blocks 801 and the inner wall of the shaft box 8. The top of the vibrating rod 5 is fixedly installed with a fixing plate 501, and the inner sides of the multiple retaining blocks 801 can be fixedly engaged with the outer wall of the fixing plate 501.

[0040] When the vibrating rod 5 and the shaft box 8 are connected, by inserting one end of the fixing plate 501 into the shaft box 8, the top of the fixing plate 501 will push the multiple retaining blocks 801 to squeeze the reset spring 802 and move backward. When the top of the fixing plate 501 contacts the top of the inner wall of the shaft box 8, the pushing of the fixing plate 501 to move is stopped. At this time, the multiple retaining blocks 801 will clamp and fix the fixing plate 501 under the elastic push of the reset spring 802, thereby realizing the connection between the vibrating rod 5 and the shaft box 8, and playing the role of fixing and installing the vibrating rod 5. By pushing the multiple retaining blocks 801 to clamp and fix the fixing plate 501 through the multiple reset springs 802, the device can fix and install vibrating rods 5 of various sizes.

[0041] like Figures 8 and 9 As shown, a plurality of limiting plates 803 are symmetrically fixedly installed on the inner wall of the shaft box 8, and the outer walls of the plurality of retaining blocks 801 are respectively slidably connected to the inner walls of the plurality of limiting plates 803;

[0042] When the retaining block 801 is pushed backward by the fixing plate 501, the retaining block 801 will move backward between the two limit plates 803. When the top of the fixing plate 501 contacts the inner wall of the vibrating rod 5, multiple retaining blocks 801 will retain the fixing plate 501 under the elastic push of the reset spring 802. The setting of the limit plate 803 plays a role in limiting the sliding of the retaining block 801, preventing the retaining block 801 from dislocating due to lack of restriction when sliding backward in the shaft box 8.

[0043] like Figures 5 and 6 As shown, the mounting assembly further includes an arc-shaped push block 702, a damping spring 701 is symmetrically provided between the bottom of the arc-shaped push block 702 and the inner wall of the connecting block 7, and the outer wall of the arc-shaped push block 702 can be slidably connected to the inner wall of the connecting block 7;

[0044] When it is necessary to connect and install this device with the arch rib, the four connecting rods 4 and the multiple connecting blocks 7 on the vertical rod 3 are pushed toward the arch rib. When the arch rib contacts the connecting block 7, the connecting block 7 continues to be pushed to move, and the arch rib will push the arc-shaped push block 702 to squeeze the vibration-damping spring 701 to slide in the connecting block 7. When the arc-shaped push block 702 is completely restricted by the arch rib and enters the connecting block 7, at this time, the multiple connecting blocks 7 will clamp and connect the arch rib through the arc-shaped push block 702, thereby realizing the connection operation between this device and the arch rib. Since the arch rib itself may vibrate to a certain extent when vibrating the arch rib, the vibration-damping spring 701 can be set to unload part of the force generated by the vibration when the arch rib itself vibrates, thereby reducing the influence of the vibration generated by the arch rib itself during vibration on the connection and retention between the arch rib and the connecting block 7, thereby preventing the present device from loosening and falling off when the arch rib is installed and connected.

[0045] like Figure 6 As shown, a soft pad 703 is fixedly installed on the top of the arc-shaped push block 702;

[0046] When the arc push block 702 moves up, the arc push block 702 will drive the soft pad 703 to move up. When the two come into contact, the arch rib will push the arc push block 702 downward through the soft pad 703, so that the connecting block 7 clamps the arch rib in place, thereby realizing the installation operation between the device and the arch rib. Through the setting of the soft pad 703, on the one hand, the contact between the arch rib and the arc push block 702 can be avoided, and it can be ensured that when the two are connected, there will be no scratches between the two due to extrusion, thereby ensuring the overall aesthetics. On the other hand, the soft pad 703 can also slow down the vibration generated by the arch rib itself, reduce the transmission of vibration, and cooperate with the vibration-damping spring 701 to better damp the vibration generated by the arch rib itself, thereby ensuring the stability of the fixed connection between the arc push block 702 and the arch rib.

[0047] like Figures 4 and 5 As shown, the outer walls of the four connecting blocks 7 are fixedly connected to the inner sides of the vertical rods 3, the inner sides of the four connecting rods 4 are fixedly mounted with slot boxes 9, the outer walls of the other four connecting blocks 7 are slidably connected to the inner walls of the four slot boxes 9, the tops of the four connecting rods 4 are fixedly mounted with rotating shafts 401, the outer walls of the four rotating shafts 401 are rotatably connected to the inner walls of the four vertical rods 3, and the tops of the four connecting rods 4 are rotatably connected to the bottoms of the four vertical rods 3;

[0048] When it is necessary to connect the device to the arch rib, multiple connecting blocks 7 located on the outer wall of the vertical rod 3 are placed on the top of the arch rib, and then the connecting rod 4 is rotated. The connecting rod 4 will rotate on the top of the vertical rod 3 through the rotating shaft 401. By rotating multiple connecting rods 4 in sequence, the connecting blocks 7 located on one side thereof are driven to rotate to the bottom of the arch rib. At this time, the rotation of the connecting rod 4 is stopped, and then the multiple connecting blocks 7 are pushed to move, so that the installation connection between the arch rib and the device can be achieved. The rotational connection between the connecting rod 4 and the vertical rod 3 makes it easier to find the installation position between the device and the arch rib when the connection operation is carried out, which is convenient for installation and disassembly.

[0049] like Figures 5 and 6 As shown, the inner wall of the trough box 9 is symmetrically fixed with an inner screw shaft 901, and the inner wall of the inner screw shaft 901 is threadedly connected with a bolt 902, and the tops of the two bolts 902 can be rotatably connected to the bottom of the connecting block 7;

[0050] When the rotating connecting rod 4 drives the connecting block 7 on one side thereof to rotate to the bottom of the arch rib, it is rotated by tightening the bolt 902. When the bolt 902 rotates, the bolt 902 will move upward through the threaded transmission in the inner screw shaft 901, and the bolt 902 will push the connecting block 7 to move in the groove box 9, thereby providing power for the moving contact between the connecting block 7 and the arch rib, and playing a role in pushing the connecting block 7 to move. By pushing the connecting block 7 on the connecting rod 4 to move upward, the multiple connecting blocks 7 symmetrically located above and below will move relative to each other to approach and contact the arch rib, thereby achieving the clamping and fixation of the arch rib.

[0051] like Figure 5 As shown, the outer walls of two of the slot boxes 9 are slidably connected with rectangular blocks 11, and the outer walls of the other two slot boxes 9 are slidably connected with interlocking blocks 12. One end of the two rectangular blocks 11 and the interlocking blocks 12 are respectively fixedly connected to the bottom of the connecting block 7 located in the four slot boxes 9. The outer walls of the two rectangular blocks 11 can be slidably connected to the inner walls of the two interlocking blocks 12 respectively. Circular holes are opened on the inner walls of one end of the two rectangular blocks 11 and the inner walls of the two interlocking blocks 12. The inner walls of the circular holes are slidably connected with positioning pins 13.

[0052] When the two connecting rods 4 are pushed to rotate relative to each other, the outer wall of the square block 11 will slide into the inner wall of the engaging block 12 through rotation. When the outer wall of the square block 11 contacts the outer wall of the groove box 9, the two connecting rods 4 will be in the same horizontal position. Then the positioning pin 13 is inserted into the circular hole between the two to realize the connection operation between the two connecting rods 4. When the connecting block 7 moves upward, it is ensured that the centers of the upper and lower connecting blocks 7 are in the same straight line. At the same time, when the device is connected to the arch rib, the connection between the two is reinforced for the second time, thereby strengthening the connection.

[0053] like Figure 7 As shown, the knocking assembly includes a knocking block 201, a rectangular plate 204 is fixedly mounted on the inner wall of the knocking box 2, the outer wall of the knocking block 201 is slidably connected to the knocking box 2 and the inner wall of the rectangular plate 204, a plurality of return springs 202 are symmetrically arranged between one side of the knocking block 201 and one side of the rectangular plate 204, a shift plate 206 is fixedly mounted on one end of the knocking block 201, the outer wall of the shift plate 206 is slidably connected to the inner wall of the knocking box 2, and a slot block 203 is fixedly mounted on one side of the shift plate 206;

[0054] When the vibrating rod 5 is driven to vibrate inside the arch rib, by pushing the slot block 203 to move, the slot block 203 will push the slapping block 201 through the shift plate 206 to pull the return block spring 202 to move, and the slapping block 201 will tap the outer wall of the arch rib, thereby tapping the concrete inside the arch rib, accelerating the divergence of bubbles in the concrete, and at the same time, it can also cooperate with the vibrating rod 5 to vibrate the concrete inside the arch rib.

[0055] like Figures 4 to 7 As shown, a pressure rod 10 is fixedly mounted on the outer wall of the shaft box 8, and the outer wall of the pressure rod 10 is slidably connected to the inner wall of the knock box 2. A plurality of tooth blocks 205 are fixedly mounted on the outer wall of the pressure rod 10, and one end of the plurality of tooth blocks 205 is symmetrically opened as an inclined sliding surface, and the outer walls of the plurality of tooth blocks 205 can be slidably connected to the inner wall of the slot block 203;

[0056] When the connection between this device and the arch rib is completed, the vibrating rod 5 is driven to vibrate inside the arch rib. During the vibration, the hydraulic cylinder 6 drives the vibrating rod 5 to move and vibrate inside the arch rib through the shaft box 8. When the shaft box 8 moves downward, the shaft box 8 will drive the pressure rod 10 to move downward, and the pressure rod 10 will push the groove block 203 through the tooth block 205, so that the groove block 203 drives the slapping block 201 to slap the outer wall of the arch rib. Through the arrangement of multiple tooth blocks 205 and return block springs 202, when the pressure rod 10 moves downward, the slapping operation of the arch rib gap can be realized, which is more conducive to cooperating with the vibrating rod 5 to vibrate the concrete.

[0057] Working principle: insert the vibrating rod 5 into the arch rib through the vibrating port on the arch rib, and then connect one end of the arch rib to the shaft box 8 through the positioning assembly in the shaft box 8. When the vibrating rod 5 is connected to the shaft box 8, the four connecting rods 4 and the installation assembly on the vertical rod 3 are used to drive the connecting block 7 to install and connect the device to the arch rib. When the device is installed with the arch rib, the vibrating rod 5 will be fixed at the top of the arch rib, so that the operator does not need to manually support the vibrating rod 5, which reduces the operator's consumption and ensures the operator's personal safety. When the concrete arch rib needs to be vibrated, the vibrating rod 5 is driven to move. The dynamic motor drives the vibrating head to operate through the flexible shaft, and the vibrating rod 5 can realize the vibrating operation of the arch rib. While vibrating, the hydraulic cylinder 6 drives the vibrating rod 5 to move up and down, so that the vibrating rod 5 moves and vibrates on the inner wall of the arch rib. Compared with vibrating at a point of the arch rib, the moving vibration can increase the vibrating area, and better vibrate the concrete in the arch rib. While the vibrating rod 5 is vibrating, the knocking assembly in the knocking box 2 knocks on the outer wall of the arch rib, thereby beating and vibrating the concrete in the arch rib, accelerating the divergence of bubbles in the concrete, and assisting the vibrating rod 5 to vibrate the concrete, thereby accelerating the vibration operation of the concrete;

[0058] When the vibrating rod 5 and the shaft box 8 are connected, by inserting one end of the fixing plate 501 into the shaft box 8, the top end of the fixing plate 501 will push the multiple retaining blocks 801 to squeeze the return spring 802 and move backward. When the top end of the fixing plate 501 contacts the top of the inner wall of the shaft box 8, the fixing plate 501 stops being pushed to move. At this time, the multiple retaining blocks 801 will clamp the fixing plate 501 under the elastic push of the return spring 802, thereby realizing the connection between the vibrating rod 5 and the shaft box 8, playing the role of fixing the vibrating rod 5 in position. By pushing the multiple retaining blocks 801 to clamp the fixing plate 501 in position through the multiple return springs 802, the device can fix and install vibrating rods 5 of various sizes.

[0059] When the retaining block 801 is pushed backward by the fixing plate 501, the retaining block 801 will move backward between the two limiting plates 803. When the top of the fixing plate 501 contacts the inner wall of the vibrating rod 5, the multiple retaining blocks 801 will be elastically pushed by the return spring 802 to retain the fixing plate 501. The setting of the limiting plates 803 plays a role in limiting the sliding of the retaining block 801, preventing the retaining block 801 from being dislocated due to lack of restraint when the retaining block 801 moves backward in the shaft box 8.

[0060] When the cam 702 is in contact with the cam 704, the cam 703 is pressed against the cam 706, and the cam 707 is pressed against the cam 708.

[0061] When the arc push block 702 moves up, the arc push block 702 will drive the soft pad 703 to move up. When the two come into contact, the arch rib will push the arc push block 702 downward through the soft pad 703, so that the connecting block 7 can clamp the arch rib in place, realizing the installation operation between the device and the arch rib. By setting the soft pad 703, on the one hand, contact between the arch rib and the arc push block 702 can be avoided, and it can be ensured that there will be no scratches between the two due to extrusion when the two are connected, thereby ensuring the overall aesthetics. On the other hand, it can also enable the soft pad 703 to slow down the vibration generated by the arch rib itself, reduce the transmission of vibration, and cooperate with the vibration-damping spring 701 to better damp the vibration generated by the arch rib itself, thereby ensuring the stability of the fixed connection between the arc push block 702 and the arch rib;

[0062] When it is necessary to connect the device to the arch rib, the multiple connecting blocks 7 located on the outer wall of the vertical rod 3 are placed on the top of the arch rib, and then the connecting rod 4 is rotated. The connecting rod 4 will rotate on the top of the vertical rod 3 through the rotating shaft 401. By rotating the multiple connecting rods 4 in sequence, the connecting block 7 located on one side thereof is driven to rotate to the bottom of the arch rib. At this time, the rotation of the connecting rod 4 is stopped, and the multiple connecting blocks 7 are then pushed to move, so that the installation connection between the arch rib and the device can be achieved. By rotating the connection between the connecting rod 4 and the vertical rod 3, the device and the arch rib can better find the installation position between the two when performing the connection operation, which is convenient for installation and disassembly.

[0063] When the connecting rod 4 is rotated to drive the connecting block 7 on one side thereof to rotate to the bottom of the arch rib, the bolt 902 is rotated. When the bolt 902 is rotated, the bolt 902 is moved upward through the threaded transmission in the inner screw shaft 901, and the bolt 902 pushes the connecting block 7 to move in the groove box 9, thereby providing power for the moving contact between the connecting block 7 and the arch rib, playing the role of pushing the connecting block 7 to move. By pushing the connecting block 7 on the connecting rod 4 to move upward, the multiple connecting blocks 7 symmetrically located above and below will move relatively to each other and come closer to the arch rib, thereby achieving the clamping and retention of the arch rib;

[0064] When the two connecting rods 4 are pushed to rotate relative to each other, the outer wall of the square block 11 will slide into the inner wall of the embedded block 12 by rotation. When the outer wall of the square block 11 contacts the outer wall of the slot box 9, the two connecting rods 4 will be in the same horizontal position. Then, the positioning pin 13 is inserted into the circular hole between the two to achieve the connection between the two connecting rods 4. When the connecting block 7 moves upward, the center of the upper and lower connecting blocks 7 are ensured to be in the same straight line. At the same time, when the device is connected to the arch rib, the connection between the two is reinforced for a second time, thereby strengthening the connection.

[0065] When the vibrating rod 5 is driven to vibrate inside the arch rib, by pushing the slot block 203 to move, the slot block 203 will push the slapping block 201 through the shift plate 206 to pull the return block spring 202 to move, and the slapping block 201 will tap the outer wall of the arch rib, thereby tapping the concrete inside the arch rib, accelerating the divergence of bubbles in the concrete, and at the same time cooperating with the vibrating rod 5 to vibrate the concrete inside the arch rib;

[0066] When the connection between this device and the arch rib is completed, the vibrating rod 5 is driven to vibrate inside the arch rib. During the vibration, the hydraulic cylinder 6 drives the vibrating rod 5 to move and vibrate inside the arch rib through the shaft box 8. When the shaft box 8 moves downward, the shaft box 8 will drive the pressure rod 10 to move downward, and the pressure rod 10 will push the groove block 203 through the tooth block 205, so that the groove block 203 drives the slapping block 201 to slap the outer wall of the arch rib. Through the arrangement of multiple tooth blocks 205 and return block springs 202, when the pressure rod 10 moves downward, the slapping operation of the arch rib gap can be realized, which is more conducive to cooperating with the vibrating rod 5 to vibrate the concrete.
