Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a construction device for multi-layer protection and hazard elimination of nodes in building waterproofing projects. Background Technology

[0002] In building waterproofing projects, especially for ground joints and nodes of large infrastructure such as roads and bridges, the quality of waterproofing construction directly affects the service life and safety of the entire structure.

[0003] Traditional waterproofing construction often uses manual brushing or simple mechanical assistance to waterproof joints, which has many limitations. On the one hand, waterproofing fillers are prone to settling or segregation during storage, leading to uneven material properties and affecting waterproofing effectiveness. On the other hand, it is difficult to precisely control the outlet position and filling amount of the filler when filling joints. For joints with complex shapes, traditional construction methods are even more difficult to achieve comprehensive and uniform filling, which can easily leave waterproofing problems.

[0004] In addition, traditional construction equipment is less flexible and cannot adapt to the needs of different construction scenarios, such as non-straight joint structures and waterproofing treatment of non-horizontal areas, which brings many inconveniences to construction.

[0005] To address the aforementioned issues, this utility model document proposes a construction device for multi-layer protection and hazard elimination at key points in building waterproofing projects. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy settling and segregation of waterproof fillers, the inconvenience in controlling the liquid outlet location, and the poor equipment flexibility leading to unsatisfactory construction results. The invention proposes a multi-layer protection and hazard elimination construction device for building waterproofing engineering nodes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Multi-layer protection and hazard elimination construction devices for building waterproofing project nodes, including:

[0009] The base plate has two support frames fixedly connected to its top, and the top of the two support frames is fixedly connected to the same liquid storage tank. A liquid filling pipe is fixedly inserted through the top of the liquid storage tank, which is used to store waterproof filler material.

[0010] A stirring assembly, installed inside the storage tank, is used to continuously stir the waterproof filler to prevent sedimentation or segregation;

[0011] A movable seat is located below the liquid storage tank and is slidably connected to the top of the base plate;

[0012] The liquid outlet and the water pump are provided. The water pump is fixedly connected to one side of the liquid storage tank. The water inlet of the water pump is connected to the inside of the liquid storage tank, and the water outlet of the water pump is connected to the liquid outlet.

[0013] A drive assembly is used to drive the movable seat to move horizontally relative to the base plate and to drive the liquid outlet head to move horizontally along the movable seat, so as to realize the position adjustment of the liquid outlet head in the horizontal and vertical directions to adapt to the filling requirements of complex joints.

[0014] In one possible design, the stirring assembly includes a rotating rod rotatably mounted inside the liquid storage tank, one end of which is sealed and rotatably extends through one side of the liquid storage tank; a first motor and an electromagnetic clutch are fixedly connected to one side of the liquid storage tank via a bracket, the output shaft of the first motor is fixedly connected to the input shaft of the electromagnetic clutch, and the output main shaft of the electromagnetic clutch is fixedly connected to one end of the rotating rod; a plurality of stirring rods are fixedly connected to the outer wall of the rotating rod, and the plurality of stirring rods are located inside the liquid storage tank.

[0015] In one possible design, the drive assembly includes two limiting grooves formed at the bottom of the movable seat, and two limiting brackets fixedly connected to the top of the base plate, the two limiting brackets being slidably connected to the inner walls of the corresponding limiting grooves; a rack is fixedly connected to one side of the movable seat, and a rotating shaft is rotatably mounted on one side of the liquid storage tank, with a gear fixedly connected to one end of the rotating shaft, the gear meshing with the rack; a second synchronous pulley is fixedly sleeved on the outer wall of the rotating shaft, and a first synchronous pulley is fixedly sleeved on the outer wall of the output shaft of the electromagnetic clutch, the first synchronous pulley and the second synchronous pulley being connected by a synchronous belt drive; by controlling the electromagnetic clutch, the gear is rotated to drive the movable seat to horizontally extend and retract.

[0016] In one possible design, the drive assembly further includes a mounting bracket fixedly connected to one side of the movable seat, with a screw rotatably mounted between the inner walls of both sides of the mounting bracket, a second motor fixedly connected to one side of the mounting bracket, and the output shaft of the second motor fixedly connected to one end of the screw; a limiting slide is fixedly connected to the side of the movable seat near the mounting bracket, a slider is slidably connected to one side of the limiting slide, the slider is threadedly connected to the screw, and the liquid outlet head is mounted on the top of the slider.

[0017] In one possible design, a fixed base is fixedly connected to the top of the slider, and a mounting block is fixedly connected to one end of the liquid outlet head. The mounting block engages with the inner wall of the fixed base to enable detachable installation of the liquid outlet head for easy maintenance or manual operation.

[0018] In one possible design, the liquid outlet is L-shaped, with a discharge port at one end and a feed port at the other end; a hose is fixedly connected to the outlet of the water pump, and the other end of the hose is fixedly connected to the feed port of the liquid outlet.

[0019] In one possible design, four casters are fixedly connected to the bottom of the base plate to facilitate the movement of the device.

[0020] In one possible design, a laser emitter is fixedly embedded at one end of the discharge port of the liquid outlet head, which is used to calibrate the position of the discharge port and the area to be treated by means of a laser spot.

[0021] In one possible design, the drive assembly transmits power in a time-sharing manner by controlling the electromagnetic clutch, enabling the first motor to simultaneously drive the movement of the mixing assembly and the moving seat, simplifying the structure and ensuring construction continuity.

[0022] In this application, when the device is put into use, the operator injects the required proportion of waterproof filler into the storage tank through the filling pipe. The first motor is started, and power is transmitted to the rotating rod via the electromagnetic clutch, causing the stirring rod to rotate continuously. This continuously and evenly stirs and mixes the filler in the storage tank, preventing material sedimentation or segregation.

[0023] When waterproofing is required at the joints of road and bridge surfaces, the equipment can be moved to the vicinity of the area to be treated. Then, the position of the liquid to be discharged can be determined by the laser emitter at one end of the liquid outlet using the position of the laser spot.

[0024] Next, by operating the electromagnetic clutch, the power of its output shaft is transmitted to the second synchronous pulley through the first synchronous pulley and synchronous belt, driving the rotating shaft and gear to rotate. The gear meshes with the rack fixed on the movable seat, pushing the movable seat horizontally outward along the limiting slide groove under the guidance of the limiting frame, allowing the movable seat to extend from the initial position to the construction area, so that the liquid outlet head moves above the joint to be treated.

[0025] After the outlet head reaches the predetermined position, the water pump is activated. The water pump draws the mixed filler from the storage tank and delivers it through pipes and hoses to the inlet of the outlet head, finally discharging it from the outlet. Simultaneously, the second motor is activated to drive the screw to rotate. The slider, threadedly connected to the screw, moves horizontally under the constraint of the limit slide, causing the outlet head fixed on top of it to move synchronously. By coordinating the horizontal pushing action of the moving seat with the horizontal movement of the outlet head on the moving seat, the horizontal and vertical positions of the outlet head within the construction plane can be flexibly adjusted, allowing it to adapt to joints of various shapes and to inject and add appropriate waterproof filler to complex joints.

[0026] After completing the construction at a specific location, the electromagnetic clutch is controlled to reverse the gears, which allows the moving seat to be horizontally returned to its initial position.

[0027] When the dispensing head needs to be replaced or maintained, the operator can remove it from the mounting base along with the mounting clip. Similarly, if the operator needs to treat areas on non-horizontal surfaces, the dispensing head can be detached and operated manually to meet the corresponding construction needs.

[0028] Beneficial effects: In this utility model, the multi-layer protection and hidden danger elimination construction device for building waterproofing engineering nodes can keep the waterproof filler in a uniform mixing state through the continuous rotation of the stirring component in the liquid storage tank, avoiding the material performance degradation caused by sedimentation or segregation, and ensuring stable grouting quality.

[0029] In this utility model, the multi-layer protection and hidden danger elimination construction device for building waterproofing engineering nodes has a movable seat that can be pushed out horizontally along the base plate. With the independent translation of the liquid outlet head on the movable seat, it can achieve horizontal and vertical dual-degree-of-freedom adjustment. This structure enables the liquid outlet head to cover a larger construction area, especially adapting to the continuous grouting needs of irregular joints such as bends and corners, reducing the number of times the equipment needs to be moved.

[0030] In this utility model, the multi-layer protection and hazard elimination construction device for building waterproofing engineering nodes utilizes an electromagnetic clutch to link the stirring and moving seat drive mechanism. Only a single motor is needed to control the stirring and pushing actions in a time-sharing manner, simplifying the power structure. The water pump and the translation motor are independently controlled, realizing the synchronous operation of material discharge and position adjustment, and improving the continuity of construction.

[0031] In this invention, the multi-layer protection and hazard elimination construction device for building waterproofing engineering nodes integrates a laser emitter at the liquid outlet. The laser emitter projects a light spot to assist operators in judging the alignment of the material drop position with the joint, reducing manual visual inspection errors and improving the filling accuracy of key nodes. At the same time, the liquid outlet can be quickly disassembled through a locking structure, facilitating maintenance or replacement. The disassembled liquid outlet can also be manually held and operated, meeting the construction needs of non-horizontal areas such as facades and ceilings, thus expanding the applicable scenarios of the device.

[0032] In this invention, the device ensures that the waterproof filler remains sufficiently uniform through continuous stirring, preventing material segregation; the horizontal extension of the moving seat and the independent translation of the liquid outlet head form a dual-degree-of-freedom adjustment, expanding the coverage area and adapting to complex joints; the electromagnetic clutch enables time-sharing control of stirring and extension actions by a single motor, simplifying the structure; laser positioning improves filling accuracy; the detachable liquid outlet head facilitates maintenance and allows for convenient manual construction operations in non-horizontal areas, ensuring the device's strong applicability.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] In one embodiment: Refer to Figure 1-7 A construction device includes: a base plate 1, a liquid storage tank 3, a stirring assembly, a movable seat 2, a liquid outlet 25, a water pump 16, and a drive assembly, etc.

[0043] In this embodiment, the base plate 1 serves as the basic support structure for the entire device. Two support frames 5 are fixedly installed on the top of the base plate 1, and a liquid storage tank 3 is fixedly installed on the top of the two support frames 5. A liquid filling pipe 15 is fixedly inserted through the top of the liquid storage tank 3, through which waterproof filler material can be added to the liquid storage tank 3 for storage.

[0044] In this embodiment, the movable seat 2 is located below the liquid storage tank 3 and between the two support frames 5. The movable seat 2 is slidably connected to the top of the base plate 1.

[0045] In this embodiment, the stirring assembly is used to stir and mix the waterproof filler material placed in the storage tank 3. The stirring assembly includes a rotating rod 7 rotatably installed inside the storage tank 3, with one end of the rotating rod 7 sealingly rotatably passing through one side of the storage tank 3. A first motor 9 and an electromagnetic clutch 10 are fixedly installed on one side of the storage tank 3 via a bracket. One end of the output shaft of the first motor 9 is fixedly connected to the input shaft of the electromagnetic clutch 10, and one end of the output main shaft of the electromagnetic clutch 10 is fixedly connected to one end of the rotating rod 7. Multiple stirring rods 8 are fixedly installed on the outer wall of the rotating rod 7, and all of the stirring rods 8 are located inside the storage tank 3. When the first motor 9 is started, the rotating rod 7 can be driven to rotate through the transmission action of the electromagnetic clutch 10, thereby causing the multiple stirring rods 8 to continuously stir the waterproof filler material stored in the storage tank 3, ensuring the uniformity of the waterproof filler material.

[0046] To achieve horizontal movement of the movable seat 2, in this embodiment, the drive assembly has two limiting grooves 17 at the bottom of the movable seat 2, and two limiting brackets 4 are fixedly installed on the top of the base plate 1. Both limiting brackets 4 are slidably connected to the inner walls of the corresponding limiting grooves 17, thereby limiting and guiding the movement of the movable seat 2. A rack 18 is fixedly installed on one side of the movable seat 2, and a rotating shaft 12 is rotatably installed on one side of the liquid storage tank 3. A gear 14 is fixedly installed at one end of the rotating shaft 12, and the gear 14 meshes with the rack 18. A second synchronous pulley 13 is fixedly sleeved on the outer wall of the rotating shaft 12, and a first synchronous pulley 11 is fixedly sleeved on the outer wall of the output shaft of the electromagnetic clutch 10. The first synchronous pulley 11 and the second synchronous pulley 13 are connected by a synchronous belt drive. By controlling the electromagnetic clutch 10, the output shaft of the electromagnetic clutch 10 can drive the first synchronous pulley 11 to rotate, which in turn drives the second synchronous pulley 13 and the rotating shaft 12 to rotate via the synchronous belt. The rotation of the rotating shaft 12 drives the gear 14 to rotate. Since the gear 14 meshes with the rack 18, the horizontal pushing and retracting operation of the moving seat 2 can be completed.

[0047] In this embodiment, the outlet head 25 is used to discharge the waterproof filler material in the storage tank 3. The water pump 16 is fixedly installed on one side of the storage tank 3. The inlet of the water pump 16 is connected to the inside of the storage tank 3 through a pipe, and the outlet of the water pump 16 cooperates with the outlet head 25. The outlet head 25 is L-shaped, with a discharge port at one end and a feed port near the other end. A hose 19 is fixedly connected to one end of the outlet of the water pump 16, and the other end of the hose 19 is fixedly connected to the feed port of the outlet head 25. When the water pump 16 is started, it can draw the waterproof filler material in the storage tank 3 and transport it through the hose 19 to the outlet head 25, and finally discharge it from the discharge port of the outlet head 25.

[0048] To achieve horizontal movement adjustment of the dispensing head 25, in this embodiment, the drive assembly further includes a mounting bracket 20 fixedly installed on one side of the movable base 2. A single screw 22 is rotatably mounted between the inner walls of both sides of the mounting bracket 20. A second motor 23 is fixedly installed on one side of the mounting bracket 20, and the output shaft of the second motor 23 is fixedly connected to one end of the screw 22. A limiting slide block 21 is fixedly installed on the side of the movable base 2 near the mounting bracket 20. A slider 24 is slidably connected to one side of the limiting slide block 21, and the slider 24 is threadedly connected to the screw 22. The dispensing head 25 is positioned on the top of the slider 24. When the second motor 23 starts, it drives the screw 22 to rotate. Since the slider 24 is threadedly connected to the screw 22 and slidably connected to the limiting slide block 21, the slider 24 can move axially along the screw 22, thereby driving the dispensing head 25 to achieve horizontal movement adjustment.

[0049] This application can be used in the field of road construction technology, or in other fields applicable to this application.

[0050] In another embodiment: Reference Figure 1 , 2 6, 7, Multi-layer protection and hazard elimination construction device for building waterproofing engineering nodes, which is applied to the field of road construction technology;

[0051] To facilitate the installation and replacement of the liquid outlet head 25, in this embodiment, a fixing seat 26 is fixedly installed on the top of the slider 24, and a mounting block 27 is fixedly installed on one end of the liquid outlet head 25. The mounting block 27 engages with the inner wall of the fixing seat 26, and the liquid outlet head 25 can be detached and placed in this way.

[0052] To assist in calibrating and positioning the outlet of the liquid outlet 25 relative to the area to be treated on the ground, in this embodiment, a laser emitter is fixedly embedded at one end of the outlet of the liquid outlet 25. The laser emitted by the laser emitter can visually determine the relative position between the outlet of the liquid outlet 25 and the area to be treated on the ground, ensuring that the waterproof filler can be accurately filled into the target area.

[0053] In this embodiment, four casters 6 are fixedly installed on the bottom of the base plate 1. The casters 6 can be used to move the entire device easily, enabling it to quickly reach different construction locations.

[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 9, electromagnetic clutch 10, water pump 16 and second motor 23 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0055] The working principle and usage process of this technical solution are as follows: When the device is put into use, the operator injects the required proportion of waterproof filler into the storage tank 3 through the liquid filling pipe 15. The first motor 9 is started, and the power is transmitted to the rotating rod 7 through the electromagnetic clutch 10, which drives the stirring rod 8 to rotate continuously, so as to continuously and evenly stir and mix the filler in the storage tank 3 to prevent the material from settling or segregating.

[0056] When waterproofing is required at the joints of road and bridge surfaces, the equipment can be moved to the vicinity of the area to be treated. Then, the position of the liquid to be discharged from the liquid outlet 25 can be determined by the position of the laser spot, which is installed at one end of the liquid outlet 25.

[0057] Next, by operating the electromagnetic clutch 10, the power of its output shaft is transmitted to the second synchronous pulley 13 through the first synchronous pulley 11 and the synchronous belt, driving the rotating shaft 12 and gear 14 to rotate. The gear 14 meshes with the rack 18 fixed on the movable seat 2, pushing the movable seat 2 horizontally outward along the limiting slide groove 17 under the guidance of the limiting frame 4, allowing the movable seat 2 to extend from its initial position to the construction area, so that the liquid outlet head 25 moves above the joint to be treated.

[0058] After the outlet head 25 reaches the predetermined position, the water pump 16 is started. The water pump 16 draws the mixed filler from the storage tank 3 and delivers it through the pipe and hose 19 to the inlet of the outlet head 25, and finally discharges it from the outlet of the outlet head 25. At the same time, the second motor 23 is started to drive the screw 22 to rotate. The slider 24, which is threaded to the screw 22, moves horizontally under the constraint of the limiting slide seat 21, driving the outlet head 25 fixed on its top to move synchronously. By coordinating the horizontal pushing action of the moving seat 2 and the horizontal movement of the outlet head 25 on the moving seat 2, the horizontal and vertical positions of the outlet head 25 in the construction plane can be flexibly adjusted, allowing it to adapt to joints of various shapes, so as to add appropriate waterproof filler to complex joints.

[0059] After completing the construction at a specific location, control the electromagnetic clutch 10 to reverse the gear 14, which can horizontally retract the movable seat 2 to the initial position.

[0060] When the dispensing head 25 needs to be replaced or maintained, the operator can remove it, along with the mounting clip 27, from the mounting base 26. Similarly, if the operator needs to treat areas on non-horizontal surfaces, the dispensing head 25 can be separated and operated manually to meet the corresponding construction needs.

[0061] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
