Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to spraying equipment for curing concrete walls. Background Technology

[0002] After concrete walls are poured and formed, they need to be sprayed with water for curing to ensure that the concrete has suitable humidity conditions during the hardening process, thereby ensuring its physical properties and durability. Spraying equipment is required when spraying water for curing concrete walls.

[0003] Existing spraying equipment often uses quick-connect couplings to facilitate rapid connection and disconnection of metal water pipes and delivery hoses. While quick-connect couplings allow for rapid assembly and disassembly, this comes at the cost of connection stability. Consequently, after prolonged use, quick-connect couplings are prone to disengagement. Furthermore, most existing spraying equipment and quick-connect couplings lack a mechanism to limit the loose delivery hose in the event of disengagement. This results in the delivery hose, in a free-flowing state, rapidly sliding away from the metal water pipe or swaying at high speed under the backlash of the sprayed water, potentially injuring workers. This significantly reduces the safety of spraying equipment. Utility Model Content

[0004] In view of this, the present invention provides a spraying device for curing concrete walls, in order to solve the problem that most spraying devices or quick-connect heads lack a mechanism to limit the loose delivery hose when the quick-connect head is disengaged.

[0005] The technical solution proposed by this utility model is: a spraying device for curing concrete walls, specifically including a metal conduit and a water supply hose, wherein a quick connector is connected between the metal conduit and the water supply hose.

[0006] The quick-connect coupling consists of a male quick-connect connector and a female quick-connect connector. A track ring is fixedly fitted onto the female quick-connect connector, and a sliding sleeve is slidably installed on the track ring by means of a spring push. An arc-shaped insertion rod is welded to the side of the sliding sleeve near the female quick-connect connector. Two connecting plates are fixedly connected between the track ring and the female quick-connect connector at intervals. A rigid straight insertion rod is slidably installed through the peripheral wall of the track ring and inserted between the two connecting plates. The arc-shaped insertion rod is inserted through and engaged with the two connecting plates and the rigid straight insertion rod. A thin steel wire rope is connected between the rigid straight insertion rod and the male quick-connect connector.

[0007] Furthermore, a connecting block is fixedly connected between the track ring and the quick-connect female head, and the connecting block and the connecting plate are arranged in a back-to-back support configuration.

[0008] Furthermore, the spring that pushes the sliding sleeve is mounted on the track ring and compressed and clamped between the sliding sleeve and the connecting block.

[0009] Furthermore, a connecting lug is welded to the outer periphery of the top part of the quick-connect male connector, the first end of the thin steel wire rope is fixedly connected to the connecting lug, and its tail end is fixedly connected to the tail end of the rigid straight plug.

[0010] Furthermore, the metal conduit and the water hose are connected by a quick-connect coupling.

[0011] Furthermore, the water delivery hose is connected to an external water pump.

[0012] The spraying equipment for concrete wall curing provided by this utility model has the following beneficial effects:

[0013] 1. When the quick-connect coupling disengages during prolonged use, the thin steel wire rope can use the power transmission of the rigid insert rod and track ring to pull and limit the quick-connect female connector and water hose in the disengaged state. This prevents the quick-connect female connector and water hose from lacking necessary restraint in this situation, and avoids them from rapidly sliding away from the metal conduit or swinging at high speed under the backlash of the water sprayed on the water hose, which could injure workers. This helps improve the safety of the spraying equipment.

[0014] Second, the sliding sleeve adopts a spring-push installation method. Simply slide it toward or away from the connecting plate to drive the arc-shaped plug rod and the rigid plug rod to engage and disengage. This allows for quick and convenient unlocking and locking of the rigid plug rod and engagement with the track ring. The release or implementation of the pull-limiting function of the quick-connect female connector and water hose by the thin steel wire rope can be performed efficiently and easily. This avoids interference with the release or implementation of this function, which would weaken the quick-connect coupling's rapid disassembly and assembly performance. Therefore, while ensuring its quick-disassembly performance, the quick-connect coupling also possesses a pull-limiting function for the quick-connect female connector and water hose, making it highly practical.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please refer to Figures 1 to 6 Example 1:

[0031] This embodiment proposes a spraying device for curing concrete walls, including a metal conduit 1 and a water supply hose 3, with a quick connector 2 connecting the metal conduit 1 and the water supply hose 3.

[0032] The quick connector 2 consists of a quick connector male 201 and a quick connector female 202. A track ring 2021 is fixedly fitted on the quick connector female 202. A sliding sleeve 2022 is slidably installed on the track ring 2021 by means of a spring push. An arc-shaped plug 2028 is welded to the side of the sliding sleeve 2022 near the quick connector female 202. Two connecting plates 2026 are fixedly connected between the track ring 2021 and the quick connector female 202. A rigid plug 2023 is slidably installed through the peripheral wall of the track ring 2021. The protruding part of the first end of the rigid plug 2023 is inserted between the two connecting plates 2026. The arc-shaped plug 2028 is inserted through and engaged with the two connecting plates 2026 and the protruding part of the first end of the rigid plug 2023. A thin steel wire rope 2025 is connected between the rigid plug 2023 and the quick connector male 201.

[0033] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0034] A connecting block 2027 is fixedly connected between the track ring 2021 and the quick-connect female head 202. The connecting block 2027 and the connecting plate 2026 are arranged to support each other in opposite directions. A spring that pushes the sliding sleeve 2022 is fitted on the track ring 2021 and is compressed and clamped between the sliding sleeve 2022 and the connecting block 2027.

[0035] Preferably, a connecting lug 2024 is welded to the outer periphery of the top part of the quick-connect male connector 201, the first end of the thin steel wire rope 2025 is fixedly connected to the connecting lug 2024, and its tail end is fixedly connected to the tail end of the rigid straight insertion rod 2023.

[0036] Preferably, the metal conduit 1 and the water hose 3 are connected by a quick connector 2.

[0037] Preferably, the water delivery hose 3 is connected to an external water delivery pump.

[0038] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:

[0039] An external water pump sequentially pressurizes and pumps curing water through a water hose 3 and a quick connector 2 into a metal conduit 1. After being pumped into the metal conduit 1, the curing water is sprayed out through a nozzle 4 and sprayed over a wide area onto the concrete wall surface to moisten and cure the concrete wall. During the spraying and curing operation, the staff needs to hold the positioning metal conduit 1 and move the nozzle 4 along the length and height of the concrete wall through the metal conduit 1 to achieve comprehensive water spraying and curing of the concrete wall surface.

[0040] When the arc-shaped insertion rod 2028 is inserted and connected to the two connecting plates 2026 and the protruding part of the first end of the rigid insertion rod 2023, the rigid insertion rod 2023 can be inserted and fixed together with the track ring 2021, and the quick-connect male head 201 and quick-connect female head 202 can be connected by a thin steel wire rope 2025. When the quick connector 2 is disengaged and separated during long-term use, the thin steel wire rope 2025 can pull and limit the quick-connect female head 202 and the water hose 3 in the free state through the power transmission of the rigid insertion rod 2023 and the track ring 2021. This prevents the quick-connect female head 202 and the water hose 3 from lacking necessary restraint in this situation. Under the backlash of the water sprayed on the water hose 3, they will rapidly move away from the metal conduit 1 or swing and shake at high speed, which could injure the staff. This helps to improve the safety of the spraying equipment.

[0041] When assembling and disassembling the quick connector 2, the rigid insertion rod 2023 needs to be engaged with the track ring 2021 to release or enable the thin steel wire rope 2025 to pull and limit the quick connector 202 and the water hose 3. The sliding sleeve 2022 adopts a spring-push installation method. Simply slide it toward or away from the connecting plate 2026 to drive the arc-shaped insertion rod 2028 to engage with the rigid insertion rod 2023, quickly and conveniently unlocking and disassembling the rigid insertion rod 2023. The locking operation involves inserting and withdrawing the rigid insertion rod 2023 and the track ring 2021. This allows the release or implementation of the pulling and limiting function of the thin steel wire rope 2025 on the quick-connect female connector 202 and the water supply hose 3 to be performed efficiently and easily. This avoids interference from the release or implementation of this function, which would weaken the quick-connect connector 2's quick-disassembly and assembly performance. As a result, the quick-connect connector 2, while ensuring its quick-disassembly performance, also has the function of pulling and limiting the quick-connect female connector 202 and the water supply hose 3, making it more practical.
