Description

Technical Field

[0001] The utility model relates to the field of tunnel construction devices, and particularly to a trolley for tunnel lining formwork treatment and concrete curing. Background Art

[0002] In the field of tunnel engineering, the secondary lining construction is a key step to ensure the long-term stability and safety of tunnels. The secondary lining not only provides necessary structural support for the tunnel to resist the formation pressure, but also plays a decisive role in the durability, waterproof performance and ultimate service performance of the tunnel. As an efficient construction method for realizing the secondary lining of tunnels, the formwork technology of lining trolleys has been widely applied in various tunnel projects. To improve the appearance quality of the secondary lining and facilitate demoulding, the formwork of the trolley needs to be polished clean and coated with demoulding agent before concrete pouring.

[0003] However, there are still some limitations in the existing technology for tunnel secondary lining construction. For example, the arc-shaped panel of the formwork trolley and the narrow operation space make it extremely difficult to apply the demoulding agent to the formwork. Under the existing technical conditions, when applying the demoulding agent in the unlined section, the splashing and dripping of the demoulding agent may contaminate the steel bars and construction joints, affecting the structural strength and the anti-seepage performance of the construction joints.

[0004] In terms of formwork grinding, manual operation requires the erection of multiple operation platforms and the grinding operation is carried out in a narrow space, resulting in a long grinding operation time, high cost, poor working environment and safety risks. At the same time, after demoulding, due to the shielding of the formwork trolley, it is difficult to effectively cure the newly poured concrete, which may affect the hardening quality of the concrete and the overall performance of the structure.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0032] Compared with the prior art, the embodiment of the present invention has the following advantages and beneficial effects:

[0033] 1. A trolley for tunnel lining formwork treatment and concrete curing provided by an embodiment of the present utility model. The body box serves as a support and accommodating component, and mechanisms such as a battery and a motor can be arranged inside. The first roller and the second roller are respectively arranged on both sides of the body box. When the trolley for curing is installed in the gap between the formwork panel and the concrete, the first roller contacts the formwork panel, and the second roller contacts the concrete structure, or the first roller contacts the concrete structure, and the second roller contacts the formwork panel. In this way, the trolley for curing can roll in the gap. The roller mechanism can polish the formwork panel or apply a release agent. Since the roller mechanism is clamped in the gap during operation, this polishing operation is not only convenient but also efficient because the rollers can drive the roller mechanism to shuttle in the gap, so that the formwork panel can be polished comprehensively. At the same time, the function of applying the release agent is achieved by the extrusion and relative rolling between the roller mechanism and the formwork panel. This process not only coats evenly but also does not contaminate the steel bars and construction joints.

[0034] 2. Two second rollers are arranged on the same side of the body box and then installed on the body box through a rocker arm. The rocker arm can drive the second roller to rotate around its connection fulcrum with the body box. A roller tension spring is arranged to connect the two rocker arms on the same side, that is, the rotation range and position state of adjacent rocker arms are restricted by the roller tension spring. Usually, the total thickness of the trolley for curing is greater than the width of the gap between the formwork panel and the concrete. When the trolley for curing is installed in the gap between the formwork panel and the concrete, the roller tension spring will deform, which can drive the rocker arm to drive the second roller to rotate downward, so that the trolley for curing is pressed tightly on the formwork panel of the trolley, and the first roller opposite to the second roller can generate sufficient friction to meet the running conditions.

[0035] 3. The rolling cylinder is connected to the body box through a cylinder bracket, and then a cylinder tension spring is arranged. In this way, under the action of the spring, the rolling cylinder can always be attached to the formwork panel. Whether in the polishing or release agent application operation, the operation efficiency can be guaranteed. Importantly, in the release agent application operation, since the rolling cylinder is always attached to the formwork panel, the rolling cylinder will not contact the concrete structure, and the release agent will only be evenly coated on the formwork panel. Because the coating operation is carried out in the already lined section, even if the release agent accidentally spills, it will not contaminate the steel bars or construction joints.

[0036] Generally speaking, the trolley for curing provided by the embodiment of the present utility model is used to be installed in the gap between the formwork panel and the concrete, driven by the first roller and the second roller, and a roller mechanism is arranged to polish or apply a release agent to the formwork panel in a fitting manner, so as to achieve the purpose of more uniform release agent application, avoiding contamination of steel bars and construction joints, facilitating the polishing of the formwork panel and the curing of newly poured concrete.

[0051] Embodiment

[0052] As Figure 1 、 Figure 3 and Figure 4 shown, a trolley for tunnel lining formwork treatment and concrete curing provided by an embodiment of the present utility model includes:

[0053] A body box 1, which has a supporting and accommodating function, and a battery, a motor, a control board, a pipeline system, etc. can be arranged inside;

[0054] A first roller 2, connected to one side of the body box 1, can be driven by a motor to rotate. When the curing trolley is installed in the gap between the formwork panel and the concrete, it contacts one side wall of the gap and generates relative rolling. Here, the side wall can be the formwork panel or the concrete structure, which is not limited here;

[0055] A second roller 3, connected to the other side of the body box 1, that is, arranged opposite to the first roller 2. Similarly, when the trolley is installed in the gap, it contacts the other side wall of the gap and generates relative rolling. Exemplarily, when the first roller 2 contacts the formwork panel, the second roller 3 contacts the concrete structure, and when the first roller 2 contacts the concrete structure, the second roller 3 contacts the formwork panel;

[0056] The roller mechanism 4 is connected to the vehicle body box 1 and can contact the formwork panel when installed in the gap between the formwork panel and the concrete. The roller mechanism 4 is configured to grind the formwork panel or apply a release agent, and comprehensively grind the formwork panel or apply a release agent during the movement of the curing trolley.

[0057] The first roller 2 is configured to contact one side wall of the gap and can roll relatively. The second roller 3 is configured to contact the other side wall of the gap and can roll relatively. The first roller 2 and the second roller 3 are jointly configured to drive the curing trolley to move in the gap between the formwork panel and the concrete. This structure allows the curing trolley to move flexibly in a narrow space, achieving comprehensive treatment of the formwork panel. At the same time, it can improve the construction efficiency and quality through an automated method. The setting of the roller mechanism 4 is particularly suitable for operations in narrow spaces, which can reduce the difficulty and risk of manual operations, while ensuring the uniformity of the release agent application and the comprehensiveness of grinding. In addition, the motor-driven rollers can provide stable power to ensure the smooth operation of the curing trolley during construction.

[0058] Exemplarily, the vehicle body box 1 is of a cuboid structure. Four first rollers 2 are provided and are respectively arranged beside the right angles at the bottom surface of the vehicle body box 1; four second rollers 3 are provided and are respectively arranged beside the right angles at the top surface of the vehicle body box 1, that is, the first rollers 2 and the second rollers 3 are correspondingly arranged and can move smoothly on the formwork panel and the concrete structure respectively, so as to ensure the smooth movement of the curing trolley in the gap. As a preferred embodiment of the present invention, each second roller 3 is connected to the vehicle body box 1 through a rocker arm, and the rocker arm can drive the second roller 3 to rotate around its connection fulcrum with the vehicle body box 1, increasing the flexibility and adaptability of the trolley. Every two second rollers 3 are arranged on the same side wall of the vehicle body box 1, and the remaining two second rollers 3 are arranged on the other side wall of the vehicle body box 1. This setting helps to balance the weight and pressure of the trolley. The two rocker arms corresponding to the two second rollers 3 on the same side wall of the vehicle body box 1 are connected by a roller tension spring 6, and the roller tension spring 6 is configured to limit the rotation angle of the rocker arm; when the curing trolley is installed in the gap between the formwork panel and the concrete, the rocker arm can drive the second roller 3 to rotate downward, so as to ensure that the first roller 2 or the second roller 3 is always in contact with the formwork panel of the trolley, which helps the trolley to press the formwork panel tightly and ensures that the roller mechanism 4 can effectively grind or apply a release agent. This structural setting enables the curing trolley to adapt to gaps of different widths, and through the cooperation of the rocker arm and the roller tension spring 6, achieve close fitting with the formwork panel and efficient operation. At the same time, the layout of the first roller 2 and the second roller 3 ensures the stability and mobility of the trolley on the formwork panel, improving the construction efficiency and quality.

[0059] Furthermore, as Figure 2As shown, the roller mechanism 4 includes a rolling cylinder 41, a roller bracket 42, and a roller tension spring 43. One end of the roller bracket 42 is detachably connected to the rolling cylinder 41, and the other end is hinged to the body box 1. One end of the roller tension spring 43 is connected to the body box 1, and the other end is connected to the roller bracket 42. The roller tension spring 43 is arranged to restrict the rotation of the roller bracket 42, so that the rolling cylinder 41 always fits the formwork panel, and the rolling cylinder 41 can rotate relative to the formwork panel. Specifically, the rolling cylinder 41 is used for grinding or applying a release agent to the formwork panel. One end of the roller bracket 42 is detachably connected to the rolling cylinder 41, allowing for the quick replacement or maintenance of the rolling cylinder 41. The other end is hinged to the body box 1, providing support and positioning for the roller mechanism 4. The roller tension spring 43 connects the body box 1 and the roller bracket 42, and its main function is to apply a pulling force to restrict the rotation of the roller bracket 42, ensuring that the rolling cylinder 41 always closely fits the formwork panel. The setting of the roller tension spring 43 ensures that the rolling cylinder 41 can maintain continuous contact with the formwork panel during grinding or coating operations, while the rolling cylinder 41 can rotate relative to the formwork panel to achieve grinding and release agent coating operations through relative friction. The setting of the roller mechanism 4 allows the curing cart to move efficiently in the gap between the formwork panel and the concrete, while maintaining close contact with the formwork panel, improving the quality and efficiency of the operation. This structure can adapt to different construction conditions, such as the irregularity of the formwork panel or the unevenness of the concrete surface. Through the adjustment of the roller tension spring 43, these changes can be accommodated.

[0060] It should be noted that the design of the rolling cylinder 41 should ensure that its surface material and structure are suitable for contacting the formwork panel and effectively completing the operation. Exemplarily, when grinding the formwork panel is required, the rolling cylinder 41 is made of a hard material. The rolling cylinder 41 can be rotated after being driven by a motor, and it can be metal, ceramic, or some plastics, etc. These materials can withstand large frictional forces and pressures, thus achieving grinding of the formwork panel and ensuring sufficient durability and wear resistance when frictionally grinding the formwork panel. It can remove impurities, rust, or other unwanted substances on the formwork surface, providing a clean surface for the uniform application of the release agent or the direct demolding of the concrete. The roller mechanism 4 can be electrically operated, improving the degree of automation and efficiency of the operation. The driving force of the motor can be adjusted to adapt to different grinding requirements and the material of the formwork panel. The rotation speed and direction can be precisely controlled, which provides more operation flexibility for the construction personnel. They can adjust the grinding intensity and effect according to the actual construction situation, and at the same time can process the formwork panel more evenly and thoroughly, reducing the unevenness or omission that may be caused by manual grinding, thereby improving the construction quality of the concrete lining.

[0061] When the release agent coating operation is required, the rolling cylinder 41 can be replaced, that is, the grinding rolling cylinder 41 is replaced with the rolling cylinder 41 for release agent coating, such asFigure 5 As shown, the rolling cylinder 41 for painting includes a central tube 7, a support tube 8 and a flexible permeable layer 9. The central tube 7 is fixedly connected to the cylinder bracket 42. The support tube 8 is sleeved outside the central tube 7. An accommodation chamber can be formed between the inner wall of the support tube 8 and the outer wall of the central tube 7. The flexible permeable layer 9 is arranged outside the support tube 8. A demoulding agent supply mechanism is arranged in the vehicle body box 1. The central tube 7 is communicated with the demoulding agent supply mechanism. The demoulding agent supply mechanism is configured to convey the demoulding agent to the central tube 7. A number of central holes 10 are arranged on the central tube 7. The central holes 10 are used to transfer the demoulding agent in the central tube 7 to the accommodation chamber. A number of tube holes 11 are arranged on the support tube 8. The tube holes 11 are used to transfer the demoulding agent in the accommodation chamber to the flexible permeable layer 9. The support tube 8 can rotate around the central tube 7. Specifically, the central tube 7 is fixedly connected to the cylinder bracket 42 and serves as a channel for demoulding agent transportation. The support tube 8 is sleeved outside the central tube 7 and jointly forms a demoulding agent transportation system with the central tube 7. An accommodation chamber is formed between the inner wall of the support tube 8 and the outer wall of the central tube 7. This is an intermediate storage mechanism for the demoulding agent to be transported from the central tube 7 to the flexible permeable layer 9. The flexible permeable layer 9 is arranged outside the support tube 8 and is used to finally uniformly paint the demoulding agent on the template panel. It should be noted that the material and structure design of the flexible permeable layer 9 should ensure that the demoulding agent can uniformly penetrate and cover the template surface, and it can be a sponge material or the like.

[0062] The demoulding agent supply mechanism is arranged in the vehicle body box 1 and is communicated with the central tube 7, responsible for conveying the demoulding agent to the central tube 7. A number of central holes 10 arranged on the central tube 7 allow the demoulding agent to be transferred from the inside of the central tube 7 to the accommodation chamber. This is a key link in the demoulding agent transportation process. A number of tube holes 11 arranged on the support tube 8 are used to further transfer the demoulding agent in the accommodation chamber to the flexible permeable layer 9 to ensure that the demoulding agent can reach the final painting layer. The support tube 8 can rotate around the central tube 7, which not only ensures the smooth progress of the painting operation, but also during the rotation of the support tube 8, it can push the demoulding agent in the accommodation chamber to be transferred from the tube holes 11 to the flexible permeable layer 9 to ensure the continuous supply of the demoulding agent. Through the joint cooperation of the central holes 10 and the tube holes 11, the demoulding agent can be uniformly passed from the central tube 7 through the accommodation chamber and finally painted on the template panel through the flexible permeable layer 9, ensuring the uniform distribution and effectiveness of the demoulding agent.

[0063] More specifically, the release agent supply mechanism includes a release agent storage tank 12, a release agent transfer pump 13, and a transfer pipeline 14. One end of the transfer pipeline 14 is communicated with the release agent storage tank 12, and the other end is communicated with the central pipe 7. The release agent transfer pump 13 is connected to the transfer pipeline 14, and a release agent filling port 15 is provided on the release agent storage tank 12. In the embodiment of the present utility model, the storage tank can store and protect the release agent to prevent volatilization or contamination to meet the release agent requirements during the construction process. The transfer pump is responsible for pumping the release agent out of the storage tank and transporting it to the central pipe 7 through the transfer pipeline 14. The transfer pipeline 14 connects the release agent storage tank 12 and the central pipe 7 to form a transfer path of the release agent from the storage tank to the roller mechanism 4. The other end of the transfer pipeline is communicated with the central pipe 7, which is the key interface for the release agent to enter the roller mechanism 4 from the transfer pipeline 14, ensuring that the release agent can smoothly flow in and be distributed to each part of the roller. The filling port provided on the release agent storage tank 12 is used to add the release agent to the storage tank. Each component of the release agent supply mechanism coordinates and cooperates to ensure that the release agent can be continuously, evenly, and effectively transported and applied to the formwork panel. To improve the construction efficiency, the release agent supply mechanism may be equipped with an automated control system to automatically adjust the transfer volume of the release agent according to the construction progress and the actual application situation of the roller mechanism 4. It should be noted that the setting quantity and distribution of the central holes 10 and the pipe holes 11 are not limited here, as long as the continuous and uniform release agent supply effect can be achieved. Generally speaking, the wider the distribution coverage area and the higher the distribution uniformity of the central holes 10 and the pipe holes 11, the better the effect, and it can be specifically set according to the actual operation requirements.

[0064] As a preferred embodiment of the present utility model, a camera 16 and a lighting lamp are provided outside the vehicle body box 1; a control main board 17 is provided inside the vehicle body box 1, and the control main board 17 is used to remotely control the moving direction and moving speed of the maintenance trolley. Specifically, the camera 16 provided outside the vehicle body box 1 enables remote monitoring. Construction workers can observe the working state of the maintenance trolley and the construction environment in real time through the camera 16 to ensure the smooth progress of the construction process. The lighting lamp provides necessary lighting for the camera 16, which is particularly important in an environment with insufficient light. It ensures that the camera 16 can clearly capture images of the construction area under any conditions. The control main board 17 provided inside the vehicle body box 1 is the core component of the trolley's intelligence, responsible for receiving remote instructions and controlling the moving direction and speed of the trolley. The control main board 17 can adjust the traveling direction of the maintenance trolley according to the construction requirements. Whether it is moving in a straight line or a curve, it can execute accurately. At the same time, it can also adjust the traveling speed of the maintenance trolley to adapt to different construction conditions and construction progress. The combination of the camera 16 and the control main board 17 enables the maintenance trolley to be equipped with intelligent systems such as automatic navigation and obstacle avoidance, further improving the automation level of the construction. The images captured by the camera 16 can be fed back to the control main board 17 as data. Through image recognition technology, the control main board 17 can analyze the construction environment and automatically adjust the running state of the trolley. The camera 16 can also be used for regular maintenance inspections of the maintenance trolley. By remotely monitoring the equipment status, problems can be discovered and solved in a timely manner. Through the integration of these functions, the maintenance trolley not only improves the automation and intelligence levels of the construction, but also enhances the monitoring ability and safety of the construction process, which is of great significance for improving the quality and efficiency of tunnel lining construction and reducing construction risks.

[0065] Of course, if concrete structure maintenance is required, a maintenance water pipe can be connected to the vehicle body box 1, and a spray head is provided at the end of the maintenance water pipe. The spray head is used to sprinkle water on the concrete for maintenance. Specifically, the maintenance water pipe is connected to the vehicle body box 1, providing a channel for transporting water source for the maintenance trolley, enabling the maintenance trolley to conveniently perform sprinkling operations in the construction area. The spray head is installed at the end of the maintenance water pipe and is responsible for evenly spraying water on the concrete surface to ensure that the concrete remains moist during the hardening process, thereby improving the strength and durability of the concrete. In order to protect the components inside the vehicle body box 1, the vehicle body box 1 of the embodiment of the present utility model includes a sealing cover. The sealing cover is used to seal the accommodation space of the vehicle body box 1 to prevent dust, moisture and other external substances from entering, protecting the internal mechanical components and electronic components, and can protect components such as the battery, motor, control main board 17, and release agent supply mechanism inside the vehicle body box 1 from being damaged, extending the service life of the equipment.

[0066] Exemplarily, the first roller 2 is a Mecanum wheel, the second roller 3 is a caster wheel, and the vehicle body box 1 is an enclosed box. Inside, there are a storage battery, a control main board 17, a release agent storage tank 12, a release agent delivery pump 13, a traveling motor, etc. On the outer shell, there are a charging interface, a discharging interface, a release agent filling port 15, a camera 16, a lighting lamp, etc. The Mecanum wheel is connected to the traveling motor, and the caster wheel is connected to the vehicle body box 1 through a rocker arm. Between the rocker arms on the same side, a roller tension spring 6 is used for connection. The rolling cylinder 41 is connected to the vehicle body box 1 through a cylinder bracket 42 and a cylinder tension spring 43. After the formwork trolley is demolded, there is a gap about 20 cm wide between the formwork panel and the concrete, and the width of this gap is adjustable within the stroke range of the trolley hydraulic cylinder. According to different tasks, the working tools on the maintenance trolley are replaced, and then the maintenance trolley is placed into this gap. Due to the installation of the cylinder tension spring 43 and the roller tension spring 6, the caster wheel and the rolling cylinder 41 can be tightly attached to the surface of the formwork panel, and the Mecanum wheel can be tightly attached to the surface of the concrete structure. By controlling the movement of the maintenance trolley, the operations of trolley grinding, release agent coating, and maintenance are completed.

[0067] More specifically, after the formwork trolley is demolded, there is a gap about 20 cm wide between the formwork panel and the concrete. The width of the gap can be adjusted according to actual requirements and is not limited here. The maintenance trolley of the embodiment of the present invention runs in this gap. The thickness of the maintenance trolley in its natural state is greater than the width of the gap. After the maintenance trolley is placed into the gap, under the tensile action of the roller tension spring 6 on the caster wheel rocker arm, the tensile force of the roller tension spring 6 on the rocker arm causes the rocker arm to close, pressing the caster wheel (the caster wheel can rotate around two perpendicular axes simultaneously under the action of the rocker arm, and the rotational combination in two directions realizes movement in any direction) tightly against the formwork panel of the trolley. The Mecanum wheel opposite to the caster wheel can then generate sufficient friction with the concrete structure to meet the running conditions. The Mecanum wheel serves as the driving wheel, and the caster wheel serves as the driven wheel. By controlling the trolley wired or wirelessly, due to the movement characteristics of the Mecanum wheel, the trolley can reach any position of the above-mentioned gap.

[0068] The grinding and coating rolling cylinder 41 is also combined with a rocker arm and a spring to press the rolling cylinder 41 tightly against the surface of the formwork panel. A motor is installed inside the grinding rolling cylinder 41, and the outer side of the rolling cylinder 41 is a sandpaper or a grinding wheel. The maintenance trolley is fixed while the grinding cylinder rotates to grind the formwork panel of the trolley. The coating rolling cylinder 41 has a hollow liquid storage structure inside and is connected to the vehicle body box 1 through a central pipe 7 to replenish the release agent at any time. The outer layer of the coating rolling cylinder 41 is made of a common cylinder material and rolls as the trolley moves (simulating manual use of a roller for coating). Exemplarily, such as Figure 6As shown in the figure, on both sides inside the rolling cylinder 41 of the grinding roller mechanism 4, a first motor cylinder 19 and a second motor cylinder 20 are symmetrically arranged. Motors are fixedly arranged inside both the first motor cylinder 19 and the second motor cylinder 20. A through hole 18 is arranged at the center of the rolling cylinder 41. The shafts of the first motor and the second motor are inserted into the through hole 18. The two motors on both sides jointly drive the rolling cylinder 41 to rotate, thereby realizing the grinding operation on the template panel. The first motor cylinder 19 and the second motor cylinder 20 can protect the motors inside, and at the same time, the symmetrically arranged motor cylinders and motors can improve the stability of the entire roller mechanism 4 and the stability of the rotation of the rolling cylinder 41.

[0069] A camera 16 is attached to the vehicle body box 1 to check the adhesion condition of the trolley template panel for targeted grinding. At the same time, the brushing quality of the release agent is checked through the camera 16 to ensure uniform brushing. Since the trolley has the feature of being able to move to the above-mentioned gaps, it can tow the maintenance water pipe and the spray head to sprinkle water on the concrete for maintenance.

[0070] Generally speaking, the maintenance trolley provided by the embodiment of the present invention uses small machinery to replace manual operations, speeds up the grinding speed of the trolley, does not require the erection of an operation platform and does not interfere with the construction of other processes, improves the operation safety (no risk of high-altitude operation) and the level of labor health protection (the existing grinding operation is carried out in a narrow space and the dust is difficult to disperse); the release agent is brushed more evenly and will not pollute the steel bars, construction joints and the waterproof structure of the construction joints (polluting the steel bars and construction joints is equivalent to demolding the steel bars and construction joints, which will cause a reduction in the lining strength, and polluting the waterproof structure will increase the risk of water leakage at the construction joints), and at the same time, the maintenance operation can be carried out immediately after demolding to achieve full coverage of concrete maintenance (the concrete requires 14 days of sprinkler maintenance. After the trolley is demolded and moves forward, it will affect the construction of the next cycle. Moving backward will block the concrete whose maintenance age is less than 14 days. Under the existing conditions, the trolley will not move after demolding and generally will block for 3 - 5 days, and the freshly demolded concrete is the most in need of sprinkler maintenance).

[0071] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and at the same time, the present invention omits the description of well-known components and processing technologies and processes to avoid unnecessarily limiting the present invention.
