Description

Technical Field

[0001] The present invention relates to the technical field of concrete construction, and in particular to intelligent maintenance equipment for precast concrete parts. Background Art

[0002] Construction projects often use some precast concrete parts, such as precast concrete blocks, precast concrete cover plates, etc. Construction projects are often located in remote mountainous areas, and the precast parts production sites are mostly temporary sites. If a scaffold is set up on the temporary site, it will need to be dismantled after the precast parts are made. The workload of setting up and dismantling the scaffold is large, and it requires huge manpower and resources. For this reason, for the production of precast concrete parts in temporary sites, the poured precast concrete parts are usually stacked on forklift pads, and then the pads and precast concrete parts are placed in an open air environment by a forklift, so that the concrete can be cured under natural conditions, and the concrete will be cured at the beginning of the curing process. During the construction period, the strength of concrete is relatively low. If it rains during this period, the surface structure of the precast parts will be easily damaged by rainwater erosion, resulting in quality problems such as sanding, roughness or reduced strength. Therefore, rainproof cloth is laid on the stacked precast concrete parts before it rains. In the process of covering the rainproof cloth, when the stacking height of the precast concrete parts is higher than the height of the workers, the rainproof cloth cannot be directly laid on the upper side of the precast concrete parts, which increases the difficulty of laying the rainproof cloth and reduces the laying efficiency. In addition, in the process of laying and removing the rainproof cloth, the rainproof cloth often rubs against the precast concrete parts and is easily damaged after long-term use, which reduces the protective performance of the rainproof cloth.

[0003] In summary, the present application proposes an intelligent maintenance device for precast concrete parts to improve the above-mentioned technical problems. Summary of the invention

[0025] When making prefabricated parts on a temporary site, the workload of setting up and dismantling scaffolding on the temporary site is large, which requires huge manpower and resources and reduces the project efficiency. Therefore, it is usually considered to place the concrete prefabricated parts in the external environment for natural curing. The following is a detailed description of the curing process of concrete prefabricated parts (hereinafter referred to as prefabricated parts): First, place the base frame 1 and its connecting parts on a flat ground in the concrete precast site, and set up an external temperature sensor through a bracket near the concrete precast site, so as to monitor the rainfall and temperature conditions in the external environment in real time. After the precast parts are cast, they are manually stacked one by one on the forklift pad, and then the forklift lifts the pad together with the precast parts as a whole and moves them to the front side of the base frame 1. At this time, the lower side of the pad is slightly higher than the upper side of the base frame 1. Then the forklift moves backwards so that the pad is accurately above the base frame 1. Finally, the forklift is controlled to descend slowly, and the pad and precast parts are placed stably on the base frame 1 to complete the entire loading operation. At this time, the prefabricated parts are in an open-air environment. When the weather outside is good, the prefabricated parts can be cured under natural conditions. When the staff finds that there are signs of rain in the external environment, they control the two electric wire-winding rollers 5 to start winding the pull rope 5001, thereby pulling the limit blocks 2002 on the left and right sides of the protective blanket 2001 to slide in the corresponding limit grooves 3001 respectively. At the same time, the first electric roller 2 is controlled to rotate and synchronously unfold the protective blanket 2001, so that the protective blanket 2001 covers the front, rear and top of the prefabricated parts. In this way, the waterproof layer on the outside of the protective blanket 2001 intercepts rainwater to prevent rainwater from directly scouring the surface of the prefabricated parts, thereby avoiding the quality problems of sanding, roughness or strength reduction of the prefabricated parts, thereby improving the quality of the prefabricated parts. The quality of the rain is improved. After the rain stops, the first electric roller 2 is controlled to reel in the protective blanket 2001, and the electric take-up roller 5 is controlled to synchronously release the pull rope 5001, so that the protective blanket 2001 is reeled into the first electric roller 2 on the front side. On this basis, the top of the door-shaped support frame 3 is set to an arch shape, so that when the protective blanket 2001 is unfolded, the top is in an arched state, so that the rainwater is guided to flow to the front and rear sides through the arched protective blanket 2001, avoiding the accumulation of rainwater on the protective blanket 2001. It should be noted that when the maintenance of the prefabricated parts is completed and the prefabricated parts need to be taken out from the base frame 1, it is also necessary to control the first electric roller 2 to reel in the protective blanket 2001, so as to facilitate the forklift to load the forklift pad and prefabricated parts from the base frame 1.

[0026] Compared with the method of manually spreading and rolling up the protective blanket 2001, by controlling the coordinated rotation of the first electric roller 2 and the electric winding roller 5, the protective blanket 2001 slides in the limiting groove 3001 through the limiting block 2002, so that the protective blanket 2001 automatically covers the top of the stacked preforms, and the automatic spreading and rolling up of the protective blanket 2001 is realized. There is no need to spread and roll up the protective blanket 2001 manually, which improves the spreading and rolling up efficiency of the protective blanket 2001, ensures that the covering is completed before it rains, and avoids the preforms from being damaged due to untimely protection. At the same time, in the process of spreading and rolling up, the friction between the protective blanket 2001 and the preforms is avoided, thereby avoiding the damage of the protective blanket 2001 due to friction.

[0027] It is also considered that when pouring precast parts in winter, if the weather temperature is below 5°C, the precast parts need to be insulated and maintained. Conventional insulation and maintenance is to wrap electric heating blankets around the stacked precast parts, and heat the precast parts through the electric heating blankets to ensure the normal hydration reaction of the concrete. At this time, the forklift pad is placed directly on the ground, and the electric heating blanket cannot cover the bottom of the forklift pad, but can only cover other parts. Therefore, the hot air flow near the forklift pad is easy to dissipate downward to the ground, reducing the heating effect of the electric heating blanket, thereby prolonging the time required for insulation and maintenance. For this reason, the ambient temperature is monitored by an external temperature sensor. When the weather temperature is below 5°C, an alarm is issued through the external temperature sensor to remind the staff that insulation and maintenance are required. Fig.12 As shown, the protective blanket 2001 is spread in front of, behind and above the preform by controlling the electric take-up roller 5, and the slide plate 6002 is manually pulled downward to extract the heat insulation blanket 6001 from the second electric rotating roller 6, so that the slide plate 6002 is fitted with the lower side of the door-shaped support frame 3, so that the middle part of the door-shaped support frame 3 is sealed by the heat insulation blanket 6001. In this way, the base frame 1, the protective blanket 2001, the door-shaped support frame 3 and the heat insulation blanket 6001 form a temporary sealed cavity together, and the electric control heating wire inside the protective blanket 2001 is controlled to start working, so that the preform in the temporary sealed cavity gradually rises. Temperature, in this process, the base frame 1 is used to prevent the hot air from diffusing to the ground, thereby improving the heating effect on the prefabricated parts and shortening the thermal insulation maintenance time. On this basis, the heat transfer from the base frame 1 to the ground is reduced by the heat insulation plate at the connection between the base frame 1 and the H-shaped steel 1001, and the thermal insulation layer of the protective blanket 2001 and the thermal insulation blanket 6001 are used to enhance the thermal insulation of the sealed cavity, thereby improving the thermal insulation maintenance effect on the prefabricated parts. It is explained here that the second electric roller 6 is controlled to rotate and the slide plate 6002 is made to slide upward to the initial position on the door-shaped support frame 3, thereby realizing the winding of the thermal insulation blanket 6001.

[0028] On this basis, during the maintenance process of the prefabricated parts, the staff is also required to regularly check the maintenance status of the prefabricated parts. If the protective blanket 2001 is opened when checking the prefabricated parts, the heat in the temporary sealed cavity will easily dissipate quickly, thus reducing the thermal insulation and maintenance effect of the protective blanket 2001. For this reason, when the staff conducts regular inspections, they control the second electric roller 6 on the gate-shaped support frame 3 on one side to reel up the insulation blanket 6001, so that the middle part of the gate-shaped support frame 3 is opened, and then the staff enters the temporary sealed cavity from the middle part of the corresponding gate-shaped support frame 3, and pushes the corresponding slide plate 6002 downward, so that the insulation blanket 6001 re-seals the middle part of the gate-shaped support frame 3, and then the staff holds a handheld lighting lamp to check the prefabricated parts in the temporary sealed cavity, thereby reducing the heat loss in the temporary sealed cavity and improving the thermal insulation and maintenance effect of the prefabricated parts.

[0029] Taking into account that the site for making prefabricated parts is usually a temporary site, after the prefabricated parts are made, it is usually necessary to transport the maintenance equipment to other temporary sites. When the maintenance equipment needs to be transferred, when the protective blanket 2001 is in the reeled state, the limit block 2002 is disengaged from the limit groove 3001, and then the electric wire take-up roller 5 is controlled to continue to release the pull rope 5001, so that the pull rope 5001 in the limit groove 3001 is in a relaxed state, and then the pull rope 5001 is manually taken out from the open side of the limit groove 3001, and the relaxed pull rope 5001 is tightened by the electric wire take-up roller 5, and then the wire is connected. The screws between the connecting plate 4 and the base frame 1 and the door-shaped support frame 3 are removed to separate the base frame 1 and the door-shaped support frame 3. This makes it easy to stack the base frame 1 and the door-shaped support frame 3, and thus facilitates the transportation of the maintenance equipment. Similarly, when installing the maintenance equipment, the pull rope 5001 needs to be pulled out from the electric wire-taking roller 5, and the pull rope 5001 is manually inserted into the open side of the limit groove 3001, and then the electric wire-taking roller 5 is controlled to tighten the pull rope 5001, and then the connecting plate 4 is fixed to the base frame 1 and the door-shaped support frame 3 by bolts, and the installation of the maintenance equipment can be completed. On this basis, Figure 3 As shown, the door-shaped support frame 3 and the base frame 1 are installed and arranged in the order of cycle intervals, so that several base frames 1 form a whole, which is convenient for the centralized stacking of prefabricated parts, and the two adjacent temporary sealed cavities are independent of each other. When the prefabricated parts in one of the temporary sealed cavities are in a heat preservation and curing state, the adjacent temporary sealed cavities can independently store or take out the prefabricated parts, thereby not affecting the curing effect of the corresponding temporary sealed cavity.

[0030] It is also taken into consideration that during the curing process of the precast parts, the moisture inside the concrete will continue to evaporate, which will lead to incomplete hydration reaction of the concrete and affect the final strength of the concrete. For this reason, the concrete needs to be regularly sprinkled with water during the curing period to keep the precast parts in a humid environment, thereby ensuring that the hydration reaction of the concrete continues. For this reason, when the base frame 1 and the corresponding door-shaped support frame 3 are installed in place, the quick self-locking plug 202 on the lower side of the door-shaped support frame 3 is synchronously inserted into the quick self-locking socket 20101 of the corresponding water storage frame 201, so that the cavity 3002 is connected to the water storage frame 201, and the water storage frames 201 on the left and right sides of the same door-shaped support frame 3 are connected through the corresponding quick self-locking The socket 20101 is connected to the quick self-locking plug 202, and then water is injected into one of the water storage frames 201 through an artificial external water pumping device, so that water can be evenly injected into all the water storage frames 201, and water is also stored at the bottom of the cavity 3002 at this time. When watering is needed, the water pump 203 is controlled to start working, so that the water in the water storage frame 201 passes through the bottom of the cavity 3002, the connecting pipe 204, the water pump 203 and the atomizing nozzle 205 in sequence, and the water is sprayed into the temporary sealed cavity in the form of water mist through the atomizing nozzle 205, thereby increasing the humidity in the temporary sealed cavity, thereby ensuring that the hydration reaction of the concrete continues and the final quality of the prefabricated parts is guaranteed.

[0031] On this basis, considering that the maintenance equipment is exposed to the external environment for a long time, when strong winds come and the protection blanket 2001 is in the unfolded state, the protection blanket 2001 will shake violently under the action of wind, which can easily cause the connection between the protection blanket 2001 and the limit block 2002 to be subjected to excessive tension. After being subjected to force for a long time, the protection blanket 2001 and the limit block 2002 are easily separated. To avoid such a situation, when the protection blanket 2001 is in the unfolded state, the electric control valve 207 is controlled to be connected with the water inlet of the water pump 203, and then the water pump 203 is controlled to start pumping water, so that water passes through the connecting pipe 204, the water pump 203, the electric control valve 207 and the branch pipe 20701 in turn, and finally enters the water bag 206. When the water bag 206 is filled with water and expanded, the water passes through the water bags 206 on both sides of the limit groove 3001. The edge of the protective blanket 2001 is clamped to reduce the shaking amplitude of the connection between the protective blanket 2001 and the limit block 2002, thereby reducing the tension at the connection between the protective blanket 2001 and the limit block 2002, avoiding the separation of the connection between the protective blanket 2001 and the limit block 2002 due to excessive force, and improving the adaptability of the protective blanket 2001 to windy weather. It is explained here that the cross-section of the water bag 206 is set to D-shape, thereby increasing the contact area between the water bag 206 and the protective blanket 2001, and improving the stability of the water bag 206 in clamping the protective blanket 2001. In addition, the edge of the protective blanket 2001 is clamped by the water bag 206 to improve the sealing of the connection between the door-shaped support frame 3 and the protective blanket 201, thereby reducing the heat loss in the temporary sealing cavity and improving the thermal insulation and maintenance effect of the protective blanket 201.

[0032] Example 2 Based on Example 1, Figure 1 and Figure 9-13 As shown, it also includes a baffle 301; two left-right symmetrical slide grooves 3003 are provided on the front and rear sides of each door-shaped support frame 3; a notch 3004 is provided on the upper side of each slide groove 3003; the front sides of the two door-shaped support frames 3 are slidably connected to a baffle 301; the rear sides of the two door-shaped support frames 3 are also slidably connected to a baffle 301; the opposite sides of the two baffles 301 are fixedly connected to two left-right symmetrical limit sliders 30101; each limit slider 3 0101 is slidably connected with the corresponding slide groove 3003; when the limit slider 30101 is located at the lowermost side of the slide groove 3003, the upper surface of the baffle 301 is higher than the upper surface of the base frame 1; each baffle 301 is provided with a guide groove 30103 on the left and right sides; each baffle 301 is slidably connected with a locking block 30104 on the left and right sides; each door-shaped support frame 3 is provided with two sockets 3006 that match the locking block 30104 on the front and rear sides.

[0033] Furthermore, in order to extend the service life of the baffle 301, the baffle 301 is made of an aluminum alloy material with good compression resistance.

[0034] It also includes a convex plate 302; a convex plate 302 is fixedly connected to the opposite sides of the two baffles 301; a drainage hole 30102 is opened on the opposite sides of the two baffles 301; each guide groove 30103 is connected with the adjacent drainage hole 30102; each door-shaped support frame 3 has two left-right symmetrical through holes 3005 on the front and rear sides; all the through holes 3005 are connected with the corresponding cavities 3002.

[0035] It also includes a filter screen 303; two left-right symmetrical filter screens 303 are fixedly connected between each baffle 301 and the adjacent convex plate 302; the filter screen 303 is L-shaped.

[0036] When a forklift is used to transport forklift pads and prefabricated parts, the forklift fork needs to be inserted and pulled between the forklift pad and the base frame 1. During this process, the fork may come into contact and rub against the base frame 1, resulting in scratches on the surface of the base frame 1. As the forklift repeatedly operates, these scratches will continue to deepen, thereby accelerating the wear and damage of the base frame 1. For this reason, the above situation is avoided by adding a baffle 301. The installation process of the baffle 301 is described below. After the base frame 1 and the door-shaped support frame 3 are connected and fixed, the limiting slider 30101 is manually aligned with the notch 3004 at the upper end of the slide groove 3003 and pushed in, and then the baffle 301 is slid downward so that the baffle 301 can slide in the slide groove 3003. In this way, the installation of the baffle 301 is completed. In the initial state, the baffle 301 is located at the lowermost side of the slide groove 3003. At this time, the upper surface of the baffle 301 is higher than the upper surface of the base frame 1.

[0037] When the staff controls the fork of the forklift to move up and down, the lower surface of the fork can be controlled to contact the upper surface of the baffle 301 first, and then the fork can be controlled to move upward and separate from the baffle 301, and the fork can be accurately positioned in the gap between the base frame 1 and the forklift pad, and then the fork can be controlled to be pulled out or pushed in between the base frame 1 and the forklift pad, and the baffle 301 is used as a buffer. In this way, the fork can be prevented from directly contacting the base frame 1, causing scratches on the surface of the base frame 1, and then accelerating the damage of the base frame 1. It is explained here that the baffle 301 is made of aluminum alloy material with excellent compressive resistance, which can withstand the impact load generated when the fork is pressed down. While ensuring the structural strength, the service life of the baffle 301 is significantly improved.

[0038] On this basis, if Fig.12As shown, when it is in the rainy season, it rains frequently in the external environment, so the protective blanket 2001 needs to frequently cover the prefabricated parts, and at the same time the prefabricated parts also need to be frequently sprinkled with water for moisture retention. At this time, the baffle plate 301 is manually pushed upward to make the lower side of the drainage hole 30102 flush with the lower side of the through hole 3005, and then the locking block 30104 is manually pushed to make the locking block 30104 inserted into the corresponding socket 3006 on the door-shaped support frame 3, and the locking block 30104 is engaged with the corresponding socket 3006, thereby limiting the sliding state of the baffle plate 301 in the slide groove 3003, and at this time, the convex plate 302 is in contact with the front side of the protective blanket 2001, so that the protective blanket 2001 is aligned with the baffle plate 301 and the convex plate 30 2 forms a temporary liquid storage tank, and the rainwater is guided to flow to the front and rear sides through the arched protective blanket 2001, so that the rainwater flows downward along the protective blanket 2001 to the temporary liquid storage tank, and then the rainwater flows to the guide grooves 30103 on the left and right sides, and passes through the corresponding drainage holes 30102 and the through holes 3005, and enters the lower part of the corresponding cavity 3002, so that the rainwater enters the water storage frame 201, reducing the number of times the water storage frame 201 is replenished with water through the external pumping device, thereby saving water. In addition, the sand and other granular impurities in the temporary liquid storage tank are intercepted by the filter screen 303 to prevent the sand and other granular impurities from entering the cavity 3002, thereby causing the cavity 3002 to be blocked.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
