Description

Technical Field

[0001] The utility model relates to a sectional curing equipment for concrete low walls. Background Art

[0002] Concrete low walls will be built on both sides of high-speed railways. The construction conditions of the concrete low walls on the bridge deck and the road surface are different. The concrete low walls on the bridge deck can be constructed by prefabrication and assembly, while the construction environment on the ground is complex and changeable. In actual construction, the formwork pouring method is usually adopted. The height of the concrete low wall is about one meter, and it is usually constructed in sections, that is, the concrete of the current section is poured on site using formwork, and the next section is constructed after demoulding. At this time, it is necessary to carry out moisture preservation curing on the demoulded concrete low wall to inhibit the loss of internal moisture of the concrete and ensure the development of concrete performance.

[0003] The existing concrete low walls mostly use the artificial spraying curing method. However, this method has low curing efficiency and poor curing effect. To ensure the construction quality and save labor costs, the current mainstream curing method tends to use an automatic spraying vehicle to sprinkle water.

[0004] Chinese patent document CN114263142A discloses an automatic spraying curing device for bridge anti-collision guardrails, which uses the reciprocating walking method of a spraying vehicle for spraying curing, including a spraying vehicle main body, a walking mechanism, a positioning mechanism, and an automatic spraying mechanism. It realizes automatic induction positioning through the cooperation of the positioning induction blocks on the positioning mechanism and the starting and stopping mechanism, controls braking and reciprocating walking; automatically adds water according to the water level, greatly improving the automation degree of the equipment.

[0005] The existing spraying vehicle has a large self-weight and high pressure on the walking wheels, which has conditional restrictions on the concrete hardening strength. The hardening strength of the just-demoulded concrete low wall is not high. In actual implementation, when the concrete strength reaches a certain hardening strength, the best curing time has actually been missed.

[0006] In addition, the above equipment needs to walk and spray frequently to relatively maintain a humidifying effect within a certain range, so the consumption of power energy and water source is relatively large. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a sectional curing equipment for concrete low walls to improve the existing spraying curing method.

[0008] To this end, the utility model provides a sectional curing equipment for concrete low walls, which includes a machine head and a curing cover. The machine head straddles the concrete low wall and is docked with the curing cover, and is used to provide pressurized spray water to the curing cover. The curing cover is a sectional assembly structure, and its length is adapted to the length of the work section. It moves with the construction of the work section. Each section includes a moving frame straddling the work section to be cured and a protective film covering the outer periphery of the moving frame to form a curing space. Among them, there is at least one spray pipe in the curing cover, and a number of nozzles are led out from each spray pipe for humidifying and curing the concrete low wall.

[0009] Furthermore, a hinge assembly and a telescopic cover are provided between the sections of the curing cover to realize the bending of the curing cover.

[0010] Furthermore, positive pressure wheels in contact with the top surface of the concrete low wall and elastic side pressure wheels in contact with the side surface of the concrete low wall are arranged on the moving frame of the curing cover.

[0011] Furthermore, the machine head includes a frame, a battery pack, a water tank, an induction water pump, a curing water supply pipeline, and a control device. Among them, the curing water supply pipeline is provided with a solenoid valve, and the control device is electrically connected to the solenoid valve for controlling the opening and closing of the solenoid valve.

[0012] Furthermore, the machine head includes a traveling mechanism for traveling to the water intake position to replenish water in the water tank. A water pipe docking assembly for waterway connection is arranged between the curing cover and the machine head. Travel switches are arranged at both ends of the machine head, and a limit block is arranged at the water intake position. The travel switch triggers a in-place signal when touching the limit block.

[0013] Furthermore, the water tank is a split water tank. The frame includes an equipment cabin and lower brackets symmetrically arranged on the left and right sides of the concrete low wall. The split water tanks are evenly arranged on the two lower brackets.

[0014] Furthermore, the traveling mechanism includes the first to fourth traveling wheels arranged from front to back in the cabin. The second and third traveling wheels are symmetrically arranged about the center of the machine head, and the span between the two satisfies that the center of gravity of the machine head is located between the two. The first and fourth traveling wheels are symmetrically arranged about the center of the machine head, and the span from the adjacent traveling wheels is greater than or equal to the width of the passage for people.

[0015] Furthermore, the sectional curing equipment for concrete low walls further includes a balanced water injection pipeline. The balanced water injection pipeline includes a tee pipe and water tank injection pipes eccentrically connected to the left and right ports of the tee pipe respectively. Among them, the middle port of the tee pipe is the water injection port at the top of the machine head to evenly distribute the water to the left and right split water tanks after injecting water into the water injection port.

[0016] Furthermore, the front and rear sides of the above-mentioned locomotive are provided with a collapse-type energy-absorbing anti-collision plate, an emergency stop button, a human body sensing anti-collision circuit breaker, and an anti-derailment circuit breaker arranged on the front belly of the locomotive and the rear belly of the maintenance cover.

[0017] Furthermore, the chassis of the above-mentioned head has a sun-proof coating on the outside and a heat-insulating layer on the inside. The control device includes a temperature sensing controller, a self-spraying pipe, and an exhaust fan. The temperature sensing controller is used to start the self-spraying pipe and the exhaust fan to cool down when the temperature inside the chassis exceeds a set upper limit value, and to close the self-spraying pipe and the exhaust fan when the temperature inside the chassis is lower than a set lower limit value.

[0018] The utility model focuses on solving the following problems by combining a machine head and a maintenance cover: the machine head is used for supplying spray water and a power source for spraying during the maintenance process; the maintenance cover is used to build a stable and controllable maintenance environment, and to perform maintenance synchronously and efficiently according to the length of the work section.

[0019] The heavy weight and high pressure of the traveling wheels of the existing spray trucks have an adverse effect on the newly demoulded concrete walls with low hardening strength. In comparison, the protective cover extends over the entire section, and the concrete low wall in the section to be cured bears less pressure, thus overcoming the conditional limitations of the existing spray trucks' own operation on the hardening strength of the concrete.

[0020] Compared with the prior art, the beneficial effects of the utility model are: 1. Maintenance by work section significantly improves the efficiency and effect of the operation. 2. A maintenance cover is used to build a stable and controllable maintenance environment, resist external interference, and realize all-weather "normalized" maintenance; 3. Achieve "low-cost" maintenance that is jointly embodied by low maintenance cost, zero labor cost and low water consumption.

[0021] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] After the existing spraying vehicle reciprocates, the concrete low wall is still exposed to the environment, and it is impossible to isolate the influence of strong wind weather, sun exposure, etc. on humidity. For example, the area just behind the spraying vehicle dries out as soon as the vehicle moves forward, resulting in the need for the spraying vehicle to frequently move and spray. This causes the battery pack to consume power very quickly and also consume water very quickly. Moreover, such maintenance requires a long time to achieve the maintenance effect, and thus the maintenance cost is very high.

[0037] In the process of implementing the high-speed rail concrete low wall spraying vehicle, the inventor of the present utility model found that: by applying a maintenance cover to the entire section to be maintained, on the one hand, it can create a good "maintenance environment", isolate the influence of external weather, and maintain humidity for a long time continuously; on the other hand, it can also save power consumption and water consumption, and thus comprehensively overcome the adverse situation of water shortage and power shortage at the construction site for maintenance.

[0038] With reference to Figures 1 to 12, the sectional curing equipment for the concrete low wall of the present utility model includes a curing cover 200 and a machine head 300. Among them, both the curing cover 200 and the machine head 300 are straddled on the concrete low wall, which is also called a protective wall.

[0039] The machine head 300 is provided with a traveling mechanism and a mechanical limiting mechanism, which are used to travel along the concrete low wall between the water intake position and the working position, and add water to the water tank at the water intake position and dock with the curing cover at the working position, including waterway docking and circuit docking.

[0040] After the formwork of the concrete low wall section is removed, a section to be cured is formed, and the curing cover 200 is moved to the section to be cured along with the section construction.

[0041] The curing cover 200 is a sectional assembled structure, and its length is adapted to the length of the section, with an overall length of 10m - 100m and each sectional length of 1m - 6m.

[0042] Each section includes a moving frame 201 straddled on the section to be cured, a protective film 202 covering the outer periphery of the moving frame, two or more groups of spray pipes 220 arranged along the length direction of the moving frame, and a number of nozzles 221 arranged on each spray pipe.

[0043] The moving frame 201 of the curing cover 200 is provided with a positive pressure wheel 205 in contact with the top surface of the concrete low wall 100 and an elastic side pressure wheel 204 in contact with the side surface of the concrete low wall 100. Both the positive pressure wheel 205 and the elastic side pressure wheel 204 are installed on the moving frame 201 in a modular form.

[0044] The moving frame 201 of the curing cover 200 is assembled on site on the first section to be cured and then moved to the section to be cured along with the subsequent section construction. The moving frame is assembled on site with aluminum alloy profiles for the frame, and its assembled configuration is shown in Figure 8 shown.

[0045] The protective film 202 continuously extends on the inner side, top surface and outer side of the moving frame 201, and is installed on the corresponding aluminum alloy profile skeleton with a pressing strip 203 to form a semi - enclosed curing environment. The protective film 202 can be selected as a PCV transparent soft curtain with a film layer thickness of 0.5mm - 1mm.

[0046] After the spray curing of the current section is completed, the curing cover needs to be moved to another section. To facilitate the bending of the entire protective cover, hinge assemblies 206 and telescopic covers 210 are provided between the sections of the curing cover of the present utility model. The hinge assemblies 206 are arranged between the moving frames of adjacent sections, and both ends of the telescopic cover are connected to adjacent sections.

[0047] In this way, the segments of the curing cover 200 can be bent separately. Meanwhile, the elastic side pressure wheels 204 on the moving frame 201 of the curing cover, which are in contact with the inner and outer sides of the concrete low wall 100, have an avoidance function, enabling individual segments to bend.

[0048] In other construction scenarios where straight-line construction is required without bending, the moving frames of the above-mentioned curing cover can be directly spliced and fixed together.

[0049] A humidity sensor head 230 for detecting humidity is provided inside the curing cover. A humidity controller (which belongs to a control module in the control device and is not shown in the figure) is provided inside the machine head. The humidity sensor head 230 is electrically connected to the humidity controller when the machine head and the curing cover are docked.

[0050] The humidification curing strategy is as follows: when the humidity controller 230 detects that the humidity inside the curing cover 200 is lower than the preset lower humidity limit value, it triggers a water supply signal, and when the humidity reaches the preset upper humidity limit value, it triggers a water supply stop signal. Among them, when the machine head 300 receives the water supply signal, it provides pressurized water flow to the spray pipeline.

[0051] Next, the functional structure of the machine head will be introduced.

[0052] The existing spray vehicle straddles the concrete low wall and includes a frame, a battery pack, a traveling mechanism, a water tank, a water pump, and a spray assembly. Among them, the water tank is located above the concrete low wall, and traveling wheels are provided on the frame.

[0053] During the spray curing process, it is found that the above-mentioned spray vehicle has the following problems: the wall of the concrete low wall usually has a passage slot for people or other groove structures. When the spray vehicle passes through the slot, it is easy to get stuck or even tip over, and then the spray vehicle cannot continue to move forward.

[0054] Therefore, the present utility model is improved from two aspects:

[0055] 1. The integral water tank is changed to a split water tank, and the arrangement above the concrete low wall is changed to a sunken arrangement, that is, symmetrically arranged on both sides of the concrete low wall, so that the center of gravity of the machine head is lowered;

[0056] 2. Since the center of gravity of the machine head does not coincide with the center of the machine head and there is a certain deviation, the present utility model arranges traveling wheels on the left and right sides of the center of the machine head so that the center of gravity falls between the two traveling wheels. At the same time, the front traveling wheels and the rear traveling wheels are symmetrically arranged with respect to the center of the machine head.

[0057] Specifically, the machine head of the present utility model includes a frame, a battery pack 311, a traveling mechanism, a split water tank 323, an induction water pump 321, a curing water supply pipeline 325, a self-spray pipeline 326, a control device 341, and an elastic side pressure wheel 333.

[0058] The frame includes an equipment cabin 351 located at the top of the concrete low wall 100 and lower brackets 352 / 353 arranged symmetrically about the left and right sides of the concrete low wall. The two lower brackets evenly arrange the split water tank 323.

[0059] The traveling mechanism includes a traveling motor 331 (preferably of a type with a large starting torque), a transmission mechanism 333, and first to fourth traveling wheels 332-1 to 332-4 arranged from front to back in the equipment cabin. The second traveling wheel 332-2 and the third traveling wheel 332-3 are symmetrically arranged about the center O of the machine head, and the span S2 between them satisfies that the center of gravity G of the machine head is located between them. The first traveling wheel 332-1 and the fourth traveling wheel 332-4 are also symmetrically arranged about the center O of the machine head, and the span S1 between them and the adjacent traveling wheels is not less than the width of the passage slot 101.

[0060] Furthermore, when water is injected at the water intake position, the water injection amounts of the left and right split water tanks should also be balanced. For this purpose, the present utility model designs a balanced water injection pipeline.

[0061] The balanced water injection pipeline includes a tee pipe 322 and water tank injection pipes 324 eccentrically connected to the left and right ports of the tee pipe 322 respectively. Among them, the inner diameter of the tee pipe 322 is much larger than the inner diameter of the water tank injection pipe 324, for example, 2 to 10 times. The left and right water tank injection pipes 324 are symmetrically arranged at the left and right ports of the tee pipe 322 and are arranged close to its top.

[0062] The middle port of the above-mentioned tee pipe 322 is the water injection port 305 at the top of the machine head. When water is injected into the water injection port 305, after the horizontal pipe of the tee pipe is filled with water, it evenly injects water into the water tank pipes on both sides. In this way, the water amounts in the left and right split water tanks are generally the same, the left and right weights of the machine head are balanced, and the machine head is prevented from tilting on the concrete low wall. The water extraction pipelines on both sides of the induction water pump 321 are symmetrically arranged to achieve balanced water extraction.

[0063] A solenoid valve is provided on the maintenance water supply pipeline 325, which is controlled according to the humidification and maintenance strategy. Another solenoid valve is provided on the self-spraying pipeline 326, which is controlled according to the heat dissipation strategy of the machine head. The induction water pump 321 is in a state of being always powered on and opens when it senses that the solenoid valve on the pipeline is powered on.

[0064] The machine head of the present utility model uses a mechanical limit mechanism to limit the stop position to meet the stability of normal operation.

[0065] The mechanical limit mechanism includes a number of limit blocks 420 and travel switches (not shown in the figure) respectively arranged at the front and rear ends of the machine head. The travel switches trigger a in-place signal when touching the limit blocks.

[0066] The limit block 420 is clamped on the low concrete wall, including a channel-shaped clamping plate 421, and clamping plates 422 / 423 connected to the left and right clamping edges of the channel-shaped clamping plate. Among them, a guiding screw 425 and a set screw 424 are provided between each clamping edge and the corresponding clamping plate. By tightening the set screw 424, the left and right clamping plates can clamp the low concrete wall, and the position is stable.

[0067] The existing spraying vehicle relies on precise optical elements for positioning. It is difficult to maintain its stable performance in the relatively dirty construction environment on site. The present invention adopts a mechanical positioning structure. Compared with the existing optical element positioning method, this mechanism has reliable positioning during operation and can adapt to the dirty construction environment on site.

[0068] During the working process, there are two limit blocks. One is the water intake position limit block that limits the water intake position of the machine head, and the other is the working position limit block that limits the working position of the machine head.

[0069] In the high-speed rail construction site, there is a large-capacity water tank (with a volume of 5 - 10 cubic meters) that provides water to the construction site, which will be moved along with the construction of each section. The water intake of the machine head of the present utility model also comes from the large-capacity water tank. A water intake pipe 410 and an electromagnetic switch are provided on the large-capacity water tank.

[0070] When reaching the water intake position, the in-place signal triggered by the travel switch is used to turn on the power supply of the water source intelligent control Q2 (which belongs to a control module in the control device 341). The water source intelligent control Q2 sends an opening signal to the water source electromagnetic switch according to the low water level signal of the water tank, and the electromagnetic switch opens the water intake pipe 410 according to the received opening signal.

[0071] The waterway connection between the curing cover 200 and the machine head 300 adopts a CE-type snap-in water pipe connection assembly 250, and the circuit connection between the curing cover and the machine head adopts a spring-loaded pin conductive contact assembly 260. A magnetic adsorption assembly 240 is also provided between the curing cover and the machine head. When the magnetic adsorption assembly 240 is powered on, the magnetic adsorption assembly 240 generates a magnetic force, tightly adsorbing the machine head 300 and the curing cover 200 together. At the same time, the waterway and the circuit are also connected in place.

[0072] A low water level relay and a high water level relay are provided in the water tank to trigger the low water level signal and the high water level signal. The low water level signal indicates water shortage, and the high water level signal indicates that the water tank is full.

[0073] Combined with reference to Figure 12 , the control strategy for the movement of the machine head of the present utility model is as follows:

[0074] S1. The machine head is at the water intake position. At this time, the travel switch on the front side of the machine head touches the water intake position limit block, triggering the in-place signal, turning on the power supply of the water source intelligent control Q2. The water source intelligent control Q2 sends an opening signal to the electromagnetic switch according to the low water level signal, opens the water source electromagnetic switch, and injects water into the machine head;

[0075] S2. When the water tank reaches the high water level, the water source intelligent control Q2 sends a closing signal to the water source electromagnetic switch according to the high water level signal to close the water source electromagnetic switch. At the same time, the high water level relay that controls the forward rotation of the motor is turned on, and the machine head moves towards the section to be cured;

[0076] S3. When the travel switch at the rear end of the machine head touches the position limit block of the section to be cured, it triggers the in-place signal, causing the magnetic adsorption component to be powered on to generate magnetic suction, docking the machine head and the protective cover, and at the same time stopping the walking motor brake;

[0077] S4. During the spray curing process, when the water level in the water tank is low and the low water level relay is triggered, the low water level relay triggers a signal to disconnect the magnetic adsorption component between the machine head and the curing cover, and reverse the walking motor to move towards the water intake position.

[0078] During the curing process, the above actions S1 - S4 are repeated until the humidification curing task is ended by shutting down. The above working logic of the machine head can be controlled by a PLC or by the logic control of electrical components.

[0079] To ensure the safe travel of the machine head, safety devices are provided on both the front and rear sides of the machine head, specifically including the collapsible energy-absorbing anti-collision plates 302 arranged at the front and rear ends of the chassis 301, the emergency stop buttons 303 arranged on the collapsible energy-absorbing anti-collision plates 302, and the optical anti-collision circuit breaker (not shown in the figure). During the low-speed travel process of the machine head (speed 5 - 10 km / h), the collapsible energy-absorbing anti-collision plate 302 first contacts the obstacle and absorbs the impact energy. The optical anti-collision circuit breaker detects the obstacle in front during the travel of the machine head and triggers shutdown when the distance is less than the set distance. Pressing the emergency stop button 303 can also cause shutdown. In addition, anti-derailment circuit breakers (not shown in the figure) are installed on the abdomen at the front end of the machine head and the abdomen at the rear end of the curing cover.

[0080] A power-off brake device (not shown in the figure) is also provided on the walking wheels to perform magnetic braking without power when replacing the battery or when the battery is out of power. This brake is powered on and in the released state when the walking motor is in the forward or reverse drive state.

[0081] During the operation of the existing spray vehicle, the spray vehicle is used outdoors. Especially in the high-temperature environment in summer, the electrical appliances need to dissipate heat to achieve air external circulation and sunshade and cooling. While being breathable, it also has to prevent rainwater intrusion. To achieve "normalized" operation, the stability of the limiters, the heat dissipation of the main engine, and the rain protection need to be solved.

[0082] The solutions of the present utility model are as follows: The outer periphery of the chassis 301 is provided with a ventilation and rainproof fish-scale hole array 304. The outer side of the chassis has a sunscreen coating and the inner side has a heat insulation layer. A temperature sensor and a cooling fan (not shown in the figure) arranged for high-temperature working areas, as well as a self-spraying pipeline 326, are provided inside the chassis. The temperature sensing controller (which belongs to a control module in the control device 341) is used to monitor the temperature inside the machine head. When the temperature inside the chassis exceeds the set upper limit value, the self-spraying pipeline (spraying the outer chassis) and the cooling fan are started. When the temperature inside the chassis is lower than the set lower limit value, the self-spraying pipeline and the cooling fan are turned off, so as to avoid protective shutdown of the equipment caused by high temperature.

[0083] In the present utility model, not only the strategy of humidity control spraying and humidification can be adopted, but also strategies such as timing control (spraying and humidifying at regular intervals) can be adopted.

[0084] In an embodiment of the present utility model, the machine head does not have the function of self-supplying water. It directly replenishes water with an external water source at the docking position and only needs to achieve the function of automatic humidification, which can greatly simplify the structure of this equipment.

[0085] Compared with the prior art, the present utility model has the following technical features / advantages:

[0086] 1. This equipment can achieve long-term continuous moisturizing and curing for the whole section according to the length of a single construction section (about 10 - 100 meters for one section). The curing cover is customized according to the length of the "section", and the whole section can be cured simultaneously. The protective film of the curing cover forms a relatively closed space to reduce the water loss rate and extend the moisturizing effect.

[0087] 2. This equipment can achieve all-weather "normalized" curing. After each section is moved and adjusted, it can achieve 24-hour non-stop curing throughout the day and is not affected by the external climate.

[0088] 3. This equipment can achieve "low-cost" curing. The machine head does not move / does not need to move back and forth frequently, with low power consumption, low failure rate and small wear. Compared with the existing spraying methods, the water consumption is low; the manual participation is less. Filling 0.5 tons of water at one time can be used for two hours, and the battery is replaced once a day (it is calculated that a set of 200ah batteries can guarantee 12 hours of operation without charging after being fully charged, and installing 2 sets of batteries for alternating charge and discharge cycle use can achieve 24-hour operation), with almost zero labor cost.

[0089] The above are only the embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
