Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a concrete curing device. Background Technology

[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength development. The gradual hardening and strength gain of concrete is a result of cement hydration, which requires specific temperature and humidity conditions. If these conditions are not present in the surrounding environment, artificial curing of the concrete is necessary.

[0003] For concrete curing, curing is essential after concrete pouring. Premature evaporation of moisture before the concrete has reached sufficient strength can cause significant shrinkage deformation and lead to drying shrinkage cracks. Therefore, curing in the initial stage after concrete pouring is crucial, and curing should begin immediately after the concrete has set. Consequently, the effort, manpower, and resources invested in subsequent concrete curing are of paramount importance.

[0004] Among existing maintenance methods, laying a concrete curing membrane is one approach. This water-saving and moisture-retaining curing membrane is made of a novel, controllable polymer material as its core, with a plastic film as the carrier, bonded together. The polymer material can absorb 200 times its own weight in water, swelling to become a transparent crystal, transforming liquid water into solid water. This solid water then continuously permeates the curing surface through capillary action, while simultaneously absorbing water evaporated during the concrete's hydration process. Therefore, the curing membrane can maintain moisture on the curing surface throughout the curing period, with a relative humidity greater than or equal to 90%, effectively inhibiting micro-cracks and ensuring project quality.

[0005] During the concrete curing membrane application process, human factors can cause gaps between membranes at the membrane's boundaries during the final setting period after pouring. This significantly reduces laying efficiency and may cause the membrane to be missed during the final setting period, leading to project quality problems.

[0006] Therefore, a concrete curing device is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a concrete curing device that, by setting a correction alarm device, automatically alarms when the angle between the handpiece and the initial straight path of the concrete curing membrane reaches a set angle during the laying of the concrete curing membrane, thus reminding the operator to perform line correction, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A concrete curing device, comprising:

[0010] The device comprises a handheld part, two retractable rods, and a roller. Two retractable rods are symmetrically and rotatably mounted on the handheld part, and both retractable rods are rotatably connected to the handheld part via a connecting shaft. The ends of the two retractable rods away from the handheld part are connected to a roller, and a concrete curing membrane is mounted on the roller.

[0011] A calibration alarm device is connected between the retractable rod and the handheld part. When the angle between the handheld part and the initial straight path of the concrete curing membrane reaches a set angle, the calibration alarm device will automatically sound an alarm.

[0012] The calibration alarm device includes a housing fixedly mounted on a handheld part. A column is rotatably mounted on a connecting shaft, and the column is located between two retractable rods. The top of the column penetrates the housing and extends to the upper side of the housing. A column fixing rod is fixedly mounted on the column. A column trigger rod is fixedly mounted at the end of the column fixing rod away from the column. The column trigger rod is an arc-shaped rod, and arc-shaped upper trigger bodies are fixedly mounted at both ends of the column trigger rod. Two arc-shaped slides that cooperate with the upper trigger bodies are symmetrically fixedly mounted on the housing. The two arc-shaped slides are located away from the column. One end of each trigger rod is elastically connected to a lower trigger body that cooperates with the upper trigger body via a second spring. A first spring is sleeved on the outer side of each of the two upper trigger bodies. Limit blocks are fixedly installed on the inner sidewalls of the two arc-shaped slides. The two ends of the first spring are fixedly connected to the column trigger rod and the limit block, respectively. An alarm indicator is fixedly installed on the top wall of the outer shell. The adjacent upper and lower trigger bodies are electrically connected to the alarm indicator. A power generation component is connected to the alarm indicator. A protective component is connected to each of the two upper trigger bodies to prevent violent collisions with the lower trigger bodies.

[0013] Based on the above scheme, the general working principle of the equipment is as follows: the operator adjusts the angle and distance between the two retraction rods and puts the concrete curing film paper tube into the roller; then the operator can operate by pulling the hand-held part. When the operator pulls the hand-held part and the initial straight path of the concrete curing film reaches the set angle during the concrete curing film laying operation, the correction alarm device will automatically sound an alarm to remind the operator to correct the line.

[0014] Preferably, the ends of the two arc-shaped slides away from the column trigger rod are elastically connected to a lower trigger body that cooperates with the upper trigger body through a second spring. A first spring is sleeved on the outer side of each of the two upper trigger bodies. A limit block is fixedly installed on the inner sidewall of each of the two arc-shaped slides, and the two ends of the first spring are fixedly connected to the column trigger rod and the limit block, respectively.

[0015] It is worth noting that if springs are not fitted on the upper and lower trigger bodies, the alarm may be frequently triggered due to small deviations during construction. Secondly, it is necessary to prevent small impacts from causing wear and tear on the upper and lower trigger bodies. To avoid the above situations, springs are fitted on the upper and lower trigger bodies. This can correct small deviations and provide a buffer protection against direct contact between the upper and lower trigger bodies.

[0016] Preferably, the protective component includes a ball mounting slot fixedly installed at one end of the column trigger rod. Two buffer balls are symmetrically installed in the ball mounting slot by means of springs. Both the ball mounting slot and the buffer balls are located in an arc-shaped slide. The inner sidewall of the arc-shaped slide is symmetrically provided with ball slots that cooperate with the two buffer balls. Each of the two ball slots is connected to a reset component that removes the buffer balls from the ball slots.

[0017] It is worth noting that without protective components, the alarm must be triggered via the electrical connection between the upper and lower trigger bodies. However, during construction, for efficiency reasons, the movements of workers may be large, leading to a violent collision between the upper and lower trigger bodies, causing the upper trigger body to break. Therefore, to prevent severe impacts during use, a ball slot is provided on the arc-shaped slide of the outer shell. When the force of a severe impact exceeds the pressure that the springs one on the upper trigger body and two on the lower trigger body can withstand, the buffer ball in the ball mounting slot pops out and locks into the ball slot, protecting the upper and lower trigger bodies and preventing them from breaking due to severe impact.

[0018] Preferably, the reset assembly includes a through hole formed in the inner wall of the tumbler slot, and a rubber retaining ring for sealing the through hole is fixedly installed on the outer wall of the arc-shaped slide.

[0019] It is worth noting that without the rubber retaining ring, when the buffer ball pops out into the ball slot, it will fall directly out through the ball slot through hole on the arc-shaped slide, failing to provide continuous locking protection for the calibration alarm device. To avoid this situation, a rubber retaining ring is installed outside the ball slot to limit the movement of the buffer ball, keeping it in the ball slot to provide continuous locking protection. This also allows the calibration alarm device to be reset and calibrated without disassembling the component.

[0020] Preferably, the power generation component includes a roller rotatably mounted on a retractable rod, the input end of the power generation component is fixedly connected to the roller, and the power generation component is fixedly mounted on the retractable rod. A connecting component for fixing the roller to the concrete curing membrane is installed on the roller.

[0021] The retractable rod is equipped with connecting components at both ends away from the connecting shaft. The connecting components include elastic saw teeth fixedly installed inside the drum. A saw tooth opening bolt is rotatably installed inside the drum, and the threaded tip of the saw tooth opening bolt contacts the elastic saw teeth.

[0022] It is worth noting that if no power generation component is installed, and the construction site does not allow it, the power supply of the calibration alarm device will be exhausted after a long period of use, and it will be impossible to find a place that can provide power to the calibration alarm device, causing the calibration alarm device to fail to sound an alarm and affecting its use. In order to avoid the above situation, the present invention selects a rolling generator as the power generation component. Since the concrete curing membrane needs to be rolled and transported during the laying process, the rolling generator in the power generation component can be driven to generate electricity in a synchronous manner.

[0023] It is worth noting that the absence of the connecting components will affect the normal operation of the power generation components. Without the connecting components, the concrete curing membrane cannot be fixedly connected to the roller. The power generation components are installed inside the roller, and the rotation of the concrete curing membrane is required to synchronously drive the generator inside the roller to rotate. The rotation of the generator converts mechanical energy into electrical energy to power the alarm. Therefore, in order to enable the power generation components to function properly, elastic saw teeth are installed on the roller. By rotating the saw teeth inside the roller, the bolts are opened, allowing the elastic saw teeth to embed into the concrete curing membrane. This allows the concrete curing membrane to drive the roller to rotate, which in turn drives the generator inside the roller to rotate.

[0024] Preferably, a fixing block is installed on the connecting shaft by a key connection, a locking block is fixedly installed on the fixing block, a locking limit hole is opened on the column fixing rod, and the locking block passes through the through hole opened at the bottom of the outer shell and cooperates with the locking limit hole to lock.

[0025] It is worth noting that by setting a limiting hole for limiting, when the concrete curing membrane equipment is in the stored state, the correction alarm device is folded and locked by the limiting hole and the locking block. If the limiting hole and the locking block are not locked, when the concrete curing equipment is in the stored state, it may be damaged by an external impact, which may damage the upper and lower trigger body structures inside the correction alarm device.

[0026] Preferably, a reference line is engraved on the top of the pillar that runs through the top wall of the outer shell, and angle lines are engraved around the outer shell near the pillar, allowing for direct observation of angular deviations.

[0027] To facilitate workers' quick assessment of any deviations in the track during the laying of the concrete curing membrane, a scale was installed, allowing them to make track corrections before the alarm sounds.

[0028] Preferredly, a counterweight is installed at the end of each of the two retractable rods that connects to the roller.

[0029] It is worth noting that the concrete curing membrane must remain in contact with the ground throughout the laying process. If the workers mishandle the membrane and it becomes suspended in mid-air, the route must be readjusted. Also, because the concrete curing membrane is small and lightweight, it may bounce off the ground and deviate from the initial route due to bumps or impacts on the road. In this case, counterweights are installed at the ends of the retraction rods where the concrete curing membrane is installed. When the concrete curing membrane is small and lightweight, these counterweights provide external pressure to keep it firmly in contact with the ground, thus ensuring work efficiency.

[0030] It is worth adding that the retractable rod adopts a retractable structure similar to the handle of a folding umbrella. By retracting the rod to reduce its length, its stability can be ensured. This prevents the rod from being bent or deformed by external impacts when it is placed in its longest position for a long time, which would affect the normal calibration alarm of the calibration alarm device.

[0031] It is worth adding that by setting the handle to a U-shape, the U-shaped structure of the handle can be larger than the overall frame of the shrinkage rod when the concrete curing membrane is not in operation and is folded, thus protecting the shrinkage rod and roller.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. Calibration alarm device: When the operator is laying the concrete curing membrane, when the angle between the operator's hand grip and the retraction rod reaches the set angle, the upper trigger body and the lower trigger body in the calibration alarm device will contact each other, and the alarm will be activated through electrical connection. The alarm will sound an alarm to remind the operator to perform line calibration.

[0034] 2. By incorporating protective devices within the calibration apparatus, two combined protective measures are proposed. The first is to use a spring as a buffer component; when subjected to a small impact force, the spring primarily acts as a buffer, protecting the calibration apparatus. The second is to use a ball as a buffer device; when subjected to a larger impact force, the pressure the spring can withstand exceeds the preset force during production, causing the ball to reach the ball slot and enter the slot, preventing the upper trigger body from further compressing the lower trigger body and avoiding breakage of the upper trigger body.

[0035] 3. The power generation component of the present invention proposes two solutions; the first is a solar power generation device, in which solar panels are installed on the outer casing, which has the lowest power generation cost, but the power generation efficiency is low on cloudy or rainy days; the second is a rolling power generation device, which has high power generation efficiency and can avoid the problem of low solar power generation efficiency on cloudy days, because the power generation device is connected to a reducer, which will cause resistance affecting the rolling of the roller, but because the number of stages of the reducer is small, this resistance can be ignored.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see Figures 1 to 5 This illustrates a first specific embodiment of the present invention;

[0045] The specific workflow is as follows:

[0046] As a preparation before installation, several points need to be explained in advance. First, the power generation component 102 is a rolling generator. Its power generation principle is that the power generation component 102 is fixed on the concrete curing membrane 4 by the elastic saw teeth 101. Then, when the concrete curing membrane 4 rotates, the power generation component 102 rotates synchronously and generates electricity.

[0047] When installing this invention, firstly, the column 514 is passed through the pre-set through hole at the bottom of the outer casing 513, and the bottom of the column 514 has a through hole. The through hole of the column 514 is fitted onto the connecting shaft 7 with the fixing block 8. One end of the connecting shaft 7 has a limiting plate 702, which limits the fixing block 8. The fixing block 8 is fixed to the connecting shaft 7 by a key connection. The column fixing rod 516 is connected to the cylindrical surface of the column 514 by a pin, and the column fixing rod 516 is installed in the middle of the column 514. The end of the column fixing rod 516 away from the column 514 is connected to the column trigger rod 511 by a pin. Both ends of the column trigger rod 511 are fixedly installed with ball mounting slots 510. Buffer balls 508 are symmetrically installed in the ball mounting slots 510. A spring 509 is installed between the two buffer balls 508. The other side of the ball mounting slots 510 is welded with... The upper trigger body 505 is aligned with the arc of the column trigger rod 511. Spring 1 504 and spring 2 503 are installed into the arc-shaped slide rail 501. The lower trigger body 502 is fitted into spring 2 503, with one cylindrical end of the lower trigger body 502 extending out of the arc-shaped slide rail 501. The lower trigger body 502 is electrically connected to the alarm 6. Then, the rubber retaining ring 507 is fitted into the ball slot 506. The upper and lower parts of the arc-shaped slide rail 501 are then installed by threaded connection. The upper part of the outer shell 513 is fixedly installed with the lower part of the outer shell 513 by buckle. The handheld part 3 is then welded to both sides of the outer shell 513. Finally, the rotating shaft 2 701 on both ends of the connecting shaft 7 and the rotating shaft 1 201 on the retraction rod 2 are connected by pins. In addition, a ball locking structure is provided on the wall of the retraction rod 2 to facilitate the retraction and storage of the retraction rod 2 and the adjustment of the distance between the two rollers 1.

[0048] During operation: The operator inserts the required concrete curing membrane 4 into the roller 1. The angle between the two shrinkage rods 2 can be adjusted according to the length of the paper tube of the concrete curing membrane 4. When the concrete curing membrane 4 is short, the shortest state of the shrinkage rods 2 and the smaller angle can also be used for installation. After the two shrinkage rods 2 are installed according to the length of the paper tube of the concrete curing membrane 4, the sawtooth opening bolt 103 is tightened. The end of the sawtooth opening bolt 103 will extend a ring of elastic saw teeth 101 fixedly installed inside the roller 1 outward from the roller 1. The saw teeth on the elastic saw teeth 101 will embed into the paper tube of the concrete curing membrane 4 for fixation. In order to drive the power generation component 102 to work and generate electricity, after the concrete curing membrane 4 is fixedly installed, the workers can pull the handheld part 3 to apply the concrete curing membrane 4 along the straight line set in the budget. During the laying process, when the angle gradually deviates from the initial straight line angle and reaches the set angle, the upper trigger body 505 and the lower trigger body 502 inside the correction alarm device 5 come into contact, the built-in electrical connection circuit forms a circuit, the buzzer in the alarm 6 sounds, and the light indicator lights up. After the workers hear or see the sound or light emitted by the alarm 6, they can correct the route.

[0049] After work: The operator manually loosens the serrated opening bolt 103 on the roller 1. After the elastic serrated teeth 101 spring back to their original position inside the roller 1, the concrete curing film 4 fitted on the two rollers 1 is removed. Then, the two retractable rods 2 are joined together and pressed down to retract to their shortest length. Then, the handle 3 drives the outer shell 513 to rotate and fold. The locking block 801 on the fixing block 8 cooperates with the locking limit hole 515 on the column fixing rod 516. At this time, the calibration alarm device 5 is locked and cannot rotate. Then, the retracted retractable rod 2 is completely surrounded by the U-shaped structure of the handle 3, with a distance of 3 cm on each of the three sides. The handle 3 protects the retractable rod 2 and the roller 1.

[0050] Example 2:

[0051] The difference from Example 1 is:

[0052] The power generation device is a solar power generation module. Although the cost of solar power generation is the lowest, the power generation efficiency is low on cloudy and rainy days. The power generation module 102 installed in the drum 1 can avoid the problem of low solar power generation efficiency on cloudy days. Because the rolling generator is connected to the reducer, the input shaft of the drum generator can rotate multiple times when the drum 1 rotates once.

[0053] It is worth noting that when a solar power generation module is used as the power generation module 102, it is not necessary to use a connecting component to fix the concrete curing membrane 4 to the roller 1, thereby reducing the complexity of the internal structure of the roller 1.

[0054] The above two embodiments are merely illustrative examples among the many embodiments of the present invention. Various variations can be made without departing from the principles of the present invention. Embodiments created by those skilled in the art through modifications to the present invention without creative effort are also within the scope of protection of the present invention.
