Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a foundation reinforcement device for buildings. Background Technology

[0002] Concrete roll compaction is a commonly used method for foundation reinforcement. It improves the bearing capacity and stability of the foundation by covering the surface of the existing foundation with a specially designed layer of concrete. First, cement, aggregates, air-entraining agents, and other raw materials are mixed and stirred according to a certain mix ratio to prepare reinforced concrete. Then, a special roller compactor is used to evenly roll the concrete onto the foundation surface. Multiple rolling passes are usually used to ensure that the concrete and the foundation are fully bonded. Concrete roll compaction can increase the bearing capacity and stability of the foundation and reduce the risk of foundation settlement and deformation.

[0003] However, existing building foundation reinforcement devices still have certain drawbacks during use. As the concrete flows and is squeezed at the inlet and outlet, a thin film of concrete adheres to the outer wall. Since the inlet and outlet are usually located in narrow or hard-to-reach places, cleaning this concrete manually is inconvenient and difficult to completely clean. Cleaning the adhered concrete requires extra time and effort, which may reduce construction efficiency. Therefore, we propose a building foundation reinforcement device. Summary of the Invention

The device is equipped with a cleaning mechanism, including a plug-in block, a slider and a cleaning plate, which can clean the outer walls of the feed hopper and the discharge hopper in all directions to maintain their cleanliness.

[0030] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0031] Example:

[0032] like Figure 1 - Figure 8As shown, this embodiment proposes a building foundation reinforcement device, including a concrete rolling equipment body 1 located at the center of the entire device, which has the function of bearing and supporting the rolling operation. A push handle 2 is provided on one side of the concrete rolling equipment body 1 for operating and pushing the equipment forward, backward, or performing rolling operations. Two sets of rolling columns 3 are provided at the bottom of the concrete rolling equipment body 1. A cone-shaped or funnel-shaped feed hopper 4 is provided at the top of the concrete rolling equipment body 1 for injecting pre-prepared concrete into the working area of ​​the rolling equipment. The bottom of the concrete rolling equipment body 1 is provided with... The discharge hopper 5, which is connected to the feed hopper 4 and has a cylindrical design, facilitates the smooth discharge of concrete through the discharge hopper 5. Inside the main body 1 of the concrete rolling equipment, two sets of drive mechanisms 6 are symmetrically arranged with the feed hopper 4 as the center. Both sets of drive mechanisms 6 are connected to guide mechanisms 7. The upper and lower ends of the guide mechanisms 7 are connected to cleaning mechanisms 8 for scraping and cleaning the feed hopper 4 and the discharge hopper 5. The side wall of the drive mechanism 6 is connected to a moving mechanism 9. The two sets of drive mechanisms 6 are connected to an integrated structure through the moving mechanism 9. The two sets of drive mechanisms 6 move up and down through the moving mechanism 9, allowing the staff to choose to clean the outer wall of the discharge hopper 5 or the feed hopper 4.

[0033] like Figure 1 , Figure 3 and 4 As shown, the drive mechanism 6 includes a motor 61 that slides up and down on the inner wall of the concrete rolling equipment body 1, a lead screw 62 connected to the output end of the motor 61, a nut 63 threaded to the outer wall of the lead screw 62, a telescopic rod 64 fixed to the outer wall of the nut 63, a connecting rod 65 with one end rotatably connected to the lead screw 62 and the other end fixed to the guide mechanism 7, and a pull rod 66 fixed to the outer wall of the connecting rod 65 and with its top end penetrating the outer wall of the concrete rolling equipment body 1; wherein the connecting rods 65 are symmetrically arranged at both ends of a set of lead screws 62, and the lead screws 62 and the connecting rods 65 are rotatably connected, one set of connecting rods 65 is close to the motor 61, and the other set of connecting rods 65 is connected to the moving mechanism 9.

[0034] like Figure 4 and Figure 6 As shown, the guiding mechanism 7 includes a guide plate 71 fixed to the end of the connecting rod 65 and located inside the main body 1 of the concrete rolling equipment, a first slot 72 opened on the side wall of the guide plate 71, a second slot 73 opened vertically through the guide plate 71, a guide block 74 movably connected in the second slot 73, a hinge shaft 75 connected to the outer wall of the guide block 74 and passing through the first slot 72 and hinged to the end of the telescopic rod 64, and two sets of plug-in blocks 76 fixed to the upper and lower ends of the guide block 74.

[0035] like Figure 3 , Figure 5 and Figure 6As shown, the cleaning mechanism 8 includes four sets of outer shell plates 81 located at the upper and lower ends of the concrete rolling equipment body 1 and near the feed hopper 4 and discharge hopper 5, an arc-shaped groove 82 opened on the outer shell plate 81, a first slider 83 slidably connected in the arc-shaped groove 82, a movable plate 84 fixed on the first slider 83, an insertion groove 85 opened in the movable plate 84 for insertion and engagement with the insertion block 76, a first cleaning plate 86 fixed on the outer wall of the upper movable plate 84 and attached to the outer wall of the feed hopper 4, and a second cleaning plate 87 fixed on the outer wall of the lower movable plate 84 and attached to the outer wall of the discharge hopper 5.

[0036] like Figure 7 and Figure 8 As shown, the moving mechanism 9 includes a first slide rod 91 fixed to the outer wall of one end of the connecting rod 65 and slidably connected to the inner wall of the concrete rolling equipment body 1; a second slide rod 92 fixed to the outer wall of the other end of the connecting rod 65 and used to connect the left and right sets of connecting rods 65; a spring 93 placed on the inner wall of the concrete rolling equipment body 1 and connected to the first slide rod 91; two sets of baffles 94 placed inside the concrete rolling equipment body 1 and corresponding to the two sets of first slide rods 91; a second slider 95 fixed to the outside of the two sets of baffles 94 and used to slide up and down to the inner wall of the concrete rolling equipment body 1; a connecting rod 96 placed inside the concrete rolling equipment body 1 and slidably connected to and fixed to the two sets of baffles 94; and a pull ring 97 fixed to the outer end of the baffles 94 and placed outside the concrete rolling equipment body 1.

[0037] The motor 61 is connected to an external switch to control its on and off states. The initial state is as follows: Figure 3 As shown, at this time, the insertion block 76 at the bottom of the guide plate 71 engages with the insertion slot 85 fixed to the second cleaning plate 87. Then, pressing the switch starts the motor 61, which drives the lead screw 62 to rotate. Because the lead nut 63 is connected to the hinge shaft 75 via the telescopic rod 64, the rotation of the lead nut 63 is restricted, so that the lead screw 62 can only move the lead nut 63 on the lead screw 62. Simultaneously, the movement of the lead nut 63 drives the hinge shaft 75 to move via the telescopic rod 64, and the hinge shaft 75 then drives the guide block 74 to slide within the guide plate 71. It is worth noting that the guide plate 71 is designed to... The two sets of motors 61 have the same curvature as the outer ring of the bottom of the feed hopper 4 and the outer ring of the discharge hopper 5. Therefore, after the two sets of motors 61 are started, they drive the two sets of plug-in blocks 76 to move simultaneously. The two sets of plug-in blocks 76 drive the plug-in slots 85 that are locked with them to move. The two sets of plug-in slots 85 drive the two sets of second cleaning plates 87 to move. The trajectory of the two sets of second cleaning plates 87 is exactly equal to the circumference of the outer ring of the discharge hopper 5, so as to perform all-round scraping and cleaning of the outer wall of the discharge hopper 5. The operator can adjust the number of times the motor 61 drives the screw nut 63 to move back and forth on the screw 62 by the switch, so as to ensure the cleanliness.

[0038] When the worker needs to clean the outer wall of the feed hopper 4, simply pull the pull rod 66 upwards, causing the pull rod 66 to move the connecting rod 65 upwards. Because the left and right sets of connecting rods 65 are connected as one piece by the second slide rod 92, the left and right sets of drive mechanisms 6 and guide mechanisms 7 slide upwards through the first slide rod 91 and the second slide rod 92. The other ends of drive mechanisms 6 and guide mechanisms 7 slide upwards on the inner wall of the concrete rolling equipment body 1 through the motor 61. During the sliding process of the first slide rod 91, the tension spring 93 deforms until the guide plate 71 drives the upper insertion block 76 to insert into the insertion groove 85 at the bottom of the first cleaning plate 86. Then, the worker pushes the pull ring 97 inwards, and the pull ring 97 drives the baffle. 94 slides inward within the main body 1 of the concrete rolling equipment via the second slider 95. Due to the connection of the connecting rod 96, the two sets of baffles 94 slide inward synchronously. After sliding to the bottom, the rear end of the baffle 94 is inserted into the bottom end of the first sliding rod 91 to support the bottom end of the first sliding rod 91. At this time, the operator can loosen the pull of the pull rod 66 and then start the switch of the motor 61. The motor 61 similarly drives the two sets of first cleaning plates 86 to slide. It is worth noting that because the feed hopper 4 is set in a funnel shape, in order to ensure that the inner wall of the first cleaning plate 86 and the outer wall of the feed hopper 4 fit together from top to bottom, the contact surface between the first cleaning plate 86 and the feed hopper 4 is set as an inclined arc surface that fits tightly against the outer wall of the feed hopper 4.

[0039] It should also be noted that the length of the pull rod 66 is greater than the height of the guide mechanism 7 when it moves from the position of the second cleaning plate 87 to the position of the first cleaning plate 86, so that the staff can pull the pull rod 66 to pull the guide mechanism 7 from the position of cleaning the discharge hopper 5 to the position of cleaning the feed hopper 4.

[0040] The main reason for separating the cleaning of feed hopper 4 and discharge hopper 5 is to improve work efficiency. Feed hopper 4 and discharge hopper 5 perform different functions and have different workloads during operation. Separating their cleaning processes allows for a more focused and efficient cleaning process. This way, cleaning personnel can concentrate on cleaning one hopper at a time without having to handle both hoppers simultaneously. This separation saves time and reduces the complexity of the cleaning work. Sometimes, only one of feed hopper 4 and discharge hopper 5 may need to be cleaned, as cleaning both simultaneously requires more motor power and increases the risk of damage.

[0041] The method of using a building foundation reinforcement device is as follows:

[0042] S1: Place the main body 1 of the concrete rolling equipment on the foundation of the building that needs to be reinforced, and ensure that the push handle 2 of the main body 1 of the rolling equipment is in the right position.

[0043] S2: Pour the pre-prepared concrete into the working area of ​​the roller compactor, i.e., feed hopper 4. Ensure that the concrete fully fills the entire working area.

[0044] S3: Press the switch of motor 61 to start motor 61. Motor 61 drives lead screw 62 to rotate. Through the connection of lead screw 63, telescopic rod 64 and hinge shaft 75, guide block 74 is driven to slide in guide plate 71.

[0045] S4: When it is necessary to clean the outer wall of the discharge hopper 5, the worker pulls the lever 66 upward, causing the connecting rod 65 to move upward. At this time, the left and right drive mechanisms 6 and guide mechanisms 7 slide upward simultaneously through the first slide rod 91 and the second slide rod 92. The guide plate 71 drives the plug block 76 to engage with the plug groove 85 at the bottom of the second cleaning plate 87.

[0046] S5: The worker pushes the pull ring 97 inward, causing the baffle 94 to slide within the main body 1 of the concrete rolling equipment. At the same time, the first cleaning plate 86 and the second cleaning plate 87 also begin to slide. In this way, the two sets of cleaning plates 86 and 87 can scrape off the dirt on the outer wall of the discharge hopper 5.

[0047] S6: After the discharge hopper 5 is cleaned, the staff can pull the pull ring 97 outward, and the baffle 94 will separate from the first slide bar 91. At this time, the spring 93's own restoring force will pull the first slide bar 91 to return to its original state, so that the guide mechanism 7 will move from the position of the discharge hopper 5 to the position of the feed hopper 4. At this time, the staff will start the switch of the motor 61 again to drive the first cleaning plate 86 to stick to the outer wall of the feed hopper 4 and perform the cleaning operation.

[0048] S7: As needed, the operator can adjust the number of times the motor 61 drives the nut 63 to move back and forth on the lead screw 62 to ensure that the required cleanliness is achieved. After cleaning is completed, turn off the motor 61.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
