Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, in particular to an adjustable grouting device and method for bridge construction. Background Art

[0002] In bridge construction, grouting, as a core technology for ensuring the stability and durability of bridge structures, is widely used in projects such as crack repair and foundation reinforcement. With the continuous advancement of modern bridge construction technology, the industry has placed higher demands on the automation, construction accuracy, and environmental adaptability of grouting equipment. Currently, bridge gaps are generally characterized by irregular curvature, which makes it very easy for slurry to overflow from the gap during the continuous grouting process, resulting in material waste and seriously affecting construction efficiency.

[0003] After searching, a patent with application number 202410659126.3 discloses a grouting device for bridge construction, in which a cleaning mechanism is provided so that when the blocking plate is lowered, the scraping plate moves downward and rotates at the same time under the pull of the pulling rope, and then the triangular plate at one end of the scraping plate can push the foreign matter on the surface of the bridge, so that the foreign matter is pushed to both sides of the scraping plate, thereby reducing the gap between the scraping plate and the bridge, avoiding the problem of some foreign matter on the surface of the bridge, resulting in the scraping plate and the bridge being unable to contact closely, causing the slurry to flow out. However, in actual use, foreign matter in the area below the blocking plate is difficult to remove, and there is a certain blind spot for cleaning foreign matter, which cannot meet the requirements of high-quality bridge grouting construction. Based on this, an adjustable grouting equipment and method for bridge construction is proposed. Summary of the Invention

[0004] The present invention proposes an adjustable grouting device and method for bridge construction, so as to solve the problem that foreign matter in the area below the existing blocking plate is difficult to remove and there are certain blind spots for foreign matter cleaning.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: an adjustable grouting device for bridge construction, comprising a base, a grouting assembly provided thereon, and further comprising: A liftable blocking member having a deployable sealing surface at its lower portion; A cleaning member, located below the blocking member, and composed of two scraping units that can move relative to each other; A moving component is arranged between the blocking member and the cleaning member, and responds to the downward movement of the blocking member. The moving component includes a translation part and a deflection part. When the blocking member moves downward, the translation part first moves to move the two parts of the cleaning member laterally away from each other. After the cleaning member moves horizontally out of the bottom of the blocking member, the deflection part moves to deflect the cleaning member outward.

[0006] Preferably, the cleaning member is composed of two scraping strips, and scraping teeth are provided at the adjacent ends of the two scraping strips.

[0007] Preferably, the translation part includes: Two slide bars are arranged opposite to each other and are hinged to each other; Two connecting blocks are respectively fixed to one end of the upper end surface of the corresponding scraper strip, and the sliding strip passes through the corresponding connecting blocks; The two first telescopic rods are respectively installed at the ends of the corresponding slide bars, and the output ends of the first telescopic rods are fixed to the connecting blocks.

[0008] Preferably, the deflection portion comprises: A vertical first motor has an articulated shaft mounted on its shaft end; a mounting frame fixed to the end of one of the slides; A gear set connected between the hinge shaft and the mounting frame, used to achieve synchronous deflection of the two slides in opposite directions; The gear set includes: a first bevel gear fixed on the outside of the hinge shaft; a third bevel gear fixed to the upper end surface of the mounting frame; The second bevel gear is meshed and connected between the first bevel gear and the third bevel gear.

[0009] Preferably, the mobile assembly further comprises a movable mounting portion, and the movable mounting portion comprises: a guide plate fixed to the end of the blocking member; A connecting plate is fixed to the outside of the slide bar, and a top end of the connecting plate is connected to a guide rod, a top end of the guide rod is fixed to a first baffle, and the guide rod passes through the guide plate; The first return spring is connected between the first baffle and the guide plate and is sleeved on the outside of the guide rod.

[0010] Preferably, it also includes a pressing assembly, which includes a through rod provided at the end of the base through a convex strip, a second baffle fixed to the top of the through rod, a second return spring provided between the second baffle and the convex strip, a pressure block fixed to the bottom end of the through rod, and a first pressure sensor embedded in the lower end face of the pressure block.

[0011] Preferably, a second pressure sensor is installed on the upper end surface of one of the scraper strips, and a spring is provided on the side wall of the blocking member.

[0012] Preferably, the blocking member comprises a main blocking plate, both ends of the lower end surface of the main blocking plate are hingedly provided with blocking bars, and a deflection assembly for synchronously deflecting the two blocking bars outward is provided above the blocking member.

[0013] Preferably, the deflection assembly comprises: A second motor is embedded in the upper end surface of the main blocking plate, and the output end of the second motor is equipped with a first spur gear via a shaft; a second spur gear fixed to a hinged rod of one of the blocking bars, and the second spur gear meshingly connected to the first spur gear; A belt connecting member is connected between the hinge rod of another blocking bar and the shaft rod at the output end of the second motor.

[0014] An adjustable bridge construction method, using the above-mentioned adjustable bridge construction grouting equipment, comprises the following steps: S1: Move the grouting equipment to the bridge gap to be grouted and place it above the gap; S2: The blocking member is lowered, and the pressing assembly and the cleaning member first contact the bridge surface. As the first pressure sensor on the pressing block receives pressure and feeds back to the controller, the controller controls the first telescopic rod to retract, so that during the blocking member's descent, the two scraping strips first move away to remove foreign matter under the blocking member; S3: The blocking member continues to descend. After the second pressure sensor on the cleaning member is squeezed by the spring, the controller controls the first telescopic rod to stop retracting and simultaneously controls the deflection part to move, causing the two cleaning members to deflect outward. S4: The sealing member is lowered to the top of the gap, and a hole is drilled into the crack using a ground drilling member. Then, mortar is injected from the drilled hole using a grouting assembly to complete the grouting operation.

[0015] In the above technical solution, the technical effects and advantages provided by the present invention are: (1) When the plugging piece moves downward, the pressure block and the cleaning piece first contact the bridge surface. The first pressure sensor senses the pressure change and feeds it back to the controller. The controller promptly controls the movement of the translation part, drives the scraper to move outward, and removes foreign matter on the bridge surface directly below the plugging piece. This ensures the sealing of the gap when the plugging piece moves downward, prevents mortar from flowing out of the gap, and greatly improves the grouting quality.

[0016] (2) After the second pressure sensor feeds back the pressure signal, the controller starts the first motor, drives the articulated shaft to rotate, and cooperates with the action of the gear set to deflect the two slides outward. This two-way cleaning action has two significant advantages: on the one hand, it realizes bilateral synchronous cleaning, greatly improves the efficiency of foreign matter removal, and reduces the cleaning time; on the other hand, the simultaneous work of both sides can more comprehensively cover the cleaning area, providing convenience for the subsequent sealing of the gap side branches.

[0017] (3) The blocking strips in the sealing piece can be synchronously deflected outwards under the action of the deflection assembly to block the smaller gaps extending beside the large gap. The deflection angle of the blocking strips is adjustable and can cope with the side gaps with different inclination angles, further reducing the possibility of mortar flowing out of the side gaps. At the same time, the outward deflection angle of the scraping strips is greater than the outward deflection angle of the blocking strips, ensuring that foreign matter in the side gaps blocked by the blocking strips is removed by the scraping strips, providing the prerequisite for the effective blocking of the blocking strips.

[0018] (4) During grouting, the outward-biased blocking strips can form a larger range of support, thereby improving the stability during grouting and avoiding problems such as poor grouting effect caused by unstable support, providing a more reliable guarantee for the quality of bridge construction.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0022] The present application provides a kind of Figures 1-10The adjustable grouting equipment for bridge construction shown in the figure includes a base 1 and a controller (not shown in the figure), the controller is used to control various electrical devices, and a plurality of movable wheels are installed at the bottom end of the base 1, at least one movable wheel is a wheel with a locking structure, and a grouting assembly 2 is provided on the base 1, and the grouting assembly 2 adopts the grouting assembly disclosed in the patent application number 202410659126.3 (A grouting device for bridge construction), which is a prior art, and the specific structure is not repeated here. In addition, the grouting assembly 2 realizes the adjustment of the grouting rate through a cement pump or a valve, and also includes a sealing member 3, a cleaning member 4 and a moving assembly 5. The sealing member 3 can be raised and lowered. Specifically, a second telescopic rod 7 is installed between the sealing member 3 and the base 1 to provide a power source for the lifting of the sealing member 3. The second telescopic rod 7 is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod, and the lower part of the sealing member 3 has an expandable Sealing surface, in the initial state, the cleaning piece 4 is located below the blocking piece 3, and the cleaning piece 4 is composed of two scraping units that can move relative to each other. The two scraping units can realize the cleaning of the bridge surface below and on the sides of the blocking piece 3 through relative movement. The surface of each scraping unit may be made of wear-resistant and corrosion-resistant materials to ensure that a good scraping effect can be maintained during use. The moving component 5 is arranged between the blocking piece 3 and the cleaning piece 4. In response to the downward movement of the blocking piece 3, precise control of the cleaning piece 4 is achieved, and the moving component 5 includes a translation part 51 and a deflection part 52, which jointly complete the movement and deflection action of the cleaning piece 4. When the blocking piece 3 moves downward, the translation part 51 first moves to make the two parts of the cleaning piece 4 move laterally away from each other. After the cleaning piece 4 moves horizontally out of the bottom of the blocking piece 3, the translation part 51 stops moving, and at the same time, the deflection part 52 moves to deflect the cleaning piece 4 outward.

[0023] Among them, see Figure 9 The cleaning piece 4 is composed of two scraping strips 41, which are symmetrically distributed. Scraping teeth 42 are provided at one end close to each other. The scraping teeth 42 can remove foreign matter from the center of the contact gap of the sealing piece 3, thereby improving the sealing performance of the direct contact between the sealing piece 3 and the bridge surface.

[0024] The pressure component 6 is also included. The pressure component 6 includes a through rod 61 provided at the end of the base 1 through a convex strip. A second baffle 65 is fixed to the top of the through rod 61. A second return spring 64 is provided between the second baffle 65 and the convex strip. A pressure block 62 is fixed to the bottom end of the through rod 61. The lower end surface of the pressure block 62 is embedded with a first pressure sensor 63. In the initial stage, the lower end surface of the pressure block 62 is flush with the lower end surface of the cleaning member 4. When the blocking member 3 moves downward, the pressure block 62 and the cleaning member 4 first contact the bridge surface. At this time, the first pressure sensor 63 senses the pressure. The controller can quickly respond to the changes in the pressure signal and timely feed back the pressure signal to the controller. After receiving the pressure signal, the controller can quickly control the movement of the translation part 51 so that the translation part 51 starts to work according to the predetermined program or parameters, thereby realizing the translation movement of the scraper 41 on the bridge surface. As the blocking member 3 continues to move downward, the bridge surface generates an upward reaction force on the pressure block 62, so that the pressure block 62 drives the penetrating rod 61 to move upward, thereby stretching the second return spring 64. At this time, the pressure monitored by the first pressure sensor 63 will gradually increase.

[0025] A second pressure sensor 10 is mounted on the upper end face of one of the scraper strips 41, and a spring clip 9 is provided on the side wall of the blocking member 3. The spring clip 9 is positioned in an elevated position. This allows the second pressure sensor 10 to move beyond a specific position as the scraper strip 41 moves, causing the spring clip 9 to contact and compress the second pressure sensor 10. This compression causes the second pressure sensor 10 to generate a pressure signal, which is transmitted to the controller. Based on the received signal, the controller can precisely control the rapid switching between the translational portion 51 and the deflection portion 52. When switching from translational motion to deflection motion is required, the controller promptly stops the translational portion 51 and simultaneously activates the deflection portion 52, using the spring clip 9's compression of the second pressure sensor 10 as a trigger signal.

[0026] See Figure 3-Figure 4 、 Figure 6-Figure 8 as well as Figure 10 , the translation part 51 includes: Two slide bars 511 are arranged opposite to each other and are hinged to each other; Two connecting blocks 513, the two connecting blocks 513 are respectively fixed to one end of the upper end surface of the corresponding scraper strip 41, the slide bar 511 passes through the corresponding connecting blocks 513, and the connecting blocks 513 can move outside the slide bar 511; The two first telescopic rods 512, the first telescopic rods 512 are preferably electric telescopic rods, and the two first telescopic rods 512 are respectively installed at the ends of the corresponding sliding bars 511, and the output ends of the first telescopic rods 512 are fixed to the connecting block 513. By starting the first telescopic rod 512 and using the first telescopic rod 512 to drive the connecting block 513 to move, the scraper 41 can be driven outward to remove foreign matter on the bridge surface just below the sealing member 3, so as to ensure the sealing of the gap when the sealing member 3 is moved down, and to prevent mortar from flowing out of the gap, thereby improving the quality of grouting. Because if the seal is not tight, mortar may flow out of these gaps during grouting operations. Once the mortar flows out, it will not only cause material waste, but also affect the fullness and density of the grouting, thereby reducing the quality of the grouting. By removing foreign matter, the sealing member 3 can be closely fitted with the bridge surface, forming a good sealing effect, thereby preventing mortar from flowing out, and greatly improving the quality of the grouting.

[0027] The deflection portion 52 comprises: A vertical first motor 522 is movable to accommodate the upward movement of the scraper strip 41 . A hinge shaft 521 is mounted on the shaft end of the first motor 522 , and the two slide bars 511 are hingedly connected via the hinge shaft 521 . A mounting frame 524 is fixed to the end of one of the slide bars 511 . The end of the other slide bar 511 is fixed to the hinge shaft 521 . The bottom end of the hinge shaft 521 is rotatably connected to the mounting frame 524 . Gear set 523, which is connected between the hinge shaft 521 and the mounting frame 524, and is used to achieve synchronous deflection of the two slide bars 511 in opposite directions; Among them, the gear set 523 includes: The first bevel gear 5231 is fixed to the outside of the hinge shaft 521; The third bevel gear 5233 is fixed to the upper end surface of the mounting frame 524; The second bevel gear 5232 is meshedly connected between the first bevel gear 5231 and the third bevel gear 5233 , and the second bevel gear 5232 is rotatably mounted on the hinge shaft 521 .

[0028] Through the above, after the second pressure sensor 10 feeds back the pressure signal, the controller starts the first motor 522, and the output end of the first motor 522 drives the hinge shaft 521 to rotate, which can drive the slide bar 511 thereon to deflect outward, thereby further expanding the removal of foreign matter. At the same time, the first bevel gear 5231 on the hinge shaft 521 drives the second bevel gear 5232 to rotate, and the second bevel gear 5232 drives the third bevel gear 5233 to rotate, so that the other slide bar 511 can also deflect outward, thereby expanding the removal of foreign matter from the other side.

[0029] This two-way cleaning action has significant advantages: on the one hand, it realizes simultaneous cleaning on both sides, greatly improving the efficiency of foreign matter removal and reducing the time required for cleaning; on the other hand, working on both sides at the same time can cover the cleaning area more comprehensively, providing convenience for subsequent sealing of gap branches.

[0030] See Figure 6-Figure 8 The moving assembly 5 also includes a movable mounting portion 53, which includes a guide plate 532, a connecting plate 531 and a first return spring 534. The guide plate 532 is fixed to the end of the blocking member 3 and is located on the same side of the translation portion 51. The connecting plate 531 is fixed to the outside of the slide bar 511, and the top of the connecting plate 531 is connected to a guide rod 533. The top of the guide rod 533 is fixed to a first baffle 535, and the guide rod 533 passes through the guide plate 532. The perforation on the guide plate 532 should be large. The cross-section of the guide rod 533 is designed to provide space for the movement of the guide rod 533 when the slide bar 511 is deflected. The first return spring 534 is connected between the first baffle 535 and the guide plate 532, and is sleeved on the outside of the guide rod 533. When the blocking member 3 moves downward, the guide rod 533 moves upward synchronously with the upward movement of the scraper 41. At this time, the first return spring 534 is in a stretched state. After the subsequent grouting is completed, when the blocking member 3 is moved upward, it can quickly return to its original position under the action of the first return spring 534.

[0031] See Figure 5 The sealing member 3 includes a main blocking plate 31, and both ends of the lower end surface of the main blocking plate 31 are provided with accommodating grooves, and a blocking strip 32 is hingedly provided in the accommodating groove. The lower end surface of the blocking strip 32 is flush with the lower end surface of the main blocking plate 31, and a deflection component 8 is provided above the blocking member 3 for synchronously deflecting the two blocking strips 32 outward. Sometimes smaller gaps may extend beside the large gap. At this time, the blocking strip 32 can be rotated out by the deflection component 8, and the blocking strip 32 is used to block the side gap, which can further reduce the outflow of mortar from the side gap, and the deflection angle of the blocking strip 32 is adjustable to cope with side gaps with different inclination angles.

[0032] It should be noted that the outward deflection angle of the scraping strip 41 is greater than the outward deflection angle of the blocking strip 32 , so that foreign matter in the side branch gap blocked by the blocking strip 32 can be removed by the scraping strip 41 .

[0033] See Figure 3 and Figure 5 , the deflection assembly 8 comprises: The second motor 81 is embedded in the upper end surface of the main blocking plate 31, and the output end of the second motor 81 is installed with a first spur gear 82 through a shaft; The second spur gear 83 and the second motor 81 are fixed to the hinge rod of one of the blocking bars 32, and the second spur gear 83 is meshedly connected to the first spur gear 82; The belt connecting member 84 is connected between the hinge rod of the other blocking bar 32 and the shaft rod of the output end of the second motor 81. The belt connecting member 84 is a combination of a belt and a pulley.

[0034] Through the above, the second motor 81 is started, and the output end of the second motor 81 is used to drive the first spur gear 82 to rotate, which can drive the second spur gear 83 to rotate, and then drive one blocking bar 32 to rotate outward. At the same time, through the action of the belt connecting member 84, the other blocking bar 32 can be rotated outward synchronously, so as to achieve the synchronous outward rotation of the two blocking bars 32.

[0035] Secondly, during grouting, the outward-biased blocking strips 32 can also form a larger range of support, improving the stability during grouting. Stable support can ensure a smoother grouting process, avoiding problems such as poor grouting effect due to unstable support, and providing a more reliable guarantee for the quality of bridge construction.

[0036] In addition, it should be noted that the present invention is also provided with a ground drilling member for drilling holes in cracks. The ground drilling member can be installed through the middle of the base 1 and can pass through the middle of the main blocking plate 31. A through hole (not shown) is opened in the middle of the main blocking plate 31 for the passage of the ground drilling member.

[0037] The present invention also provides an adjustable bridge construction method, which uses the above-mentioned adjustable bridge construction grouting equipment and includes the following steps: S1: Move the grouting equipment to the bridge gap to be grouted and place it above the gap; S2: The blocking member 3 is lowered, and the pressing assembly 6 and the cleaning member 4 first contact the bridge surface. As the first pressure sensor 63 on the pressing block 62 receives pressure and feeds back to the controller, the controller controls the first telescopic rod 512 to retract. As the blocking member 3 descends, the two scraping strips 41 first move away to remove foreign matter under the blocking member 3. S3: The blocking member 3 continues to descend. After the second pressure sensor 10 on the cleaning member 4 is squeezed by the spring 9, the controller controls the first telescopic rod 512 to stop retracting and simultaneously controls the deflection portion 52 to move, causing the two cleaning members 4 to deflect outward. S4: The plugging member 3 is lowered to be above the gap, and a hole is drilled into the crack using the ground drilling member. Then, the grouting assembly 2 is used to inject mortar from the drilled hole to complete the grouting operation.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

As the first pressure sensor (63) on the pressure block (62) is pressed and fed back to the controller, the controller controls the first telescopic rod (512) to retract, so that during the lowering process of the blocking member (3), the two scraping strips (41) first move away to remove foreign matter below the blocking member (3); S3: The blocking member (3) continues to descend, and after the second pressure sensor (10) on the cleaning member (4) is squeezed by the spring (9), the controller controls the first telescopic rod (512) to stop retracting, and synchronously controls the deflection portion (52) to move, causing the two cleaning members (4) to deflect outward; S4: The plugging member (3) is lowered to the position above the crack, and a hole is drilled into the crack using the ground drilling member. Then, mortar is injected from the drilled hole using the grouting assembly (2) to complete the grouting operation.
