Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an automatic maintenance trolley. Background Technology

[0002] With the rapid development of hydropower and waterway construction and the continuous expansion of the scale of water conservancy and waterway projects, the requirements for the degree of automation of water conservancy and waterway projects are also getting higher and higher. The concrete of the inner wall of the water conveyance corridor of the lock often involves the problem of curing. If the curing effect is not good, it will directly affect the quality of the concrete and make it difficult to guarantee the quality of the concrete.

[0003] In existing technologies, the water conveyance channels of long-channel ship locks are relatively long and have small cross-sectional dimensions. When multiple sections are constructed continuously, the long channels make it difficult to maintain the long-term moist curing state of the inner wall concrete by relying solely on manual maintenance, thus making it difficult to achieve the desired concrete curing effect. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic curing trolley to solve the problem in the above-mentioned background technology that the water conveyance channel of the long corridor ship lock is long and has a small cross-sectional size. When multiple sections are constructed continuously, the channel is long, and it is difficult to maintain the long-term moist curing state of the inner wall concrete by relying solely on manual curing, so it is difficult to achieve the purpose of good concrete curing effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An automatic maintenance trolley includes a trolley frame. The trolley frame is characterized in that: an all-round spraying component is provided on the top of the trolley frame, and the all-round spraying component is used to realize all-round spraying maintenance of the corridor; positioning and moving components are provided on the front and back of the trolley frame, and the positioning and moving components are used to limit the position of the trolley frame to maintain the uniformity of spraying.

[0007] The omnidirectional spraying assembly includes a spraying water tank, which is located on the top of the trolley frame. A submersible pump is installed inside the spraying water tank, and a transmission pipe is installed at the output end of the submersible pump. A spraying pipe is installed at the end of the transmission pipe, and a fixing frame is installed on the inner side of the spraying pipe. The fixing frame is located on the top of the trolley frame.

[0008] The positioning and moving component includes a telescopic push rod, which is located on the front and back of the fixed frame. A limit bracket is installed on the outer side of the output end of the telescopic push rod, and a positioning wheel is provided on the inner side of the limit bracket.

[0009] Preferably, crossbars are installed between the fixed frames, and a drain valve is provided on the back of the lower end of the spray tank, and a travel circuit breaker sensor is provided on the inner side of the left end of the trolley frame.

[0010] Preferably, a control box is installed on the right side of the spray tank, and a box cover is embedded on the right side of the control box, and a controller is installed on the left side inside the control box.

[0011] Preferably, an automatic retractable electric drum reel is installed on the top of the water tank, and a connecting end is installed on the right side of the upper end of the automatic retractable electric drum reel, with a connecting wire provided on the inner side of the connecting end.

[0012] Preferably, a drive motor is installed at the bottom inside the control box, and a transmission belt is provided on the outer side of the output end of the drive motor. Two sets of walking rubber wheels are connected to the inner side of the end of the transmission belt through pulleys, and a limit plate is provided on the outer side of the walking rubber wheels. The limit plate is located at the bottom of the trolley frame.

[0013] Preferably, the outer side of the spray pipe is provided with several sets of high-pressure atomizing nozzles.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model, equipped with an all-around spraying assembly, utilizes a spraying water tank to provide water for spray curing. An internal submersible pump injects curing water into the spray pipes via a transmission pipe. High-pressure atomizing nozzles on the spray pipes then evenly spray the water onto the inner walls of the corridor. The entire device moves within the corridor using rubber wheels and an internal motor, achieving fully automatic and all-around corridor curing. This avoids prolonged exposure of personnel to the enclosed environment of the corridor, ensuring personnel safety and guaranteeing that every inch of the corridor wall is adequately moistened. It prevents quality problems such as reduced concrete strength and cracks caused by untimely or uneven curing. This concrete curing trolley has a wide range of applications, strong adaptability, intelligent control, precise spraying, simple and convenient operation, and high reusability, greatly reducing construction labor intensity, ensuring project quality, and improving project durability, resulting in significant economic and social benefits.

[0017] 2. This utility model, by installing a positioning and moving component, addresses the issue that when the device moves within the corridor after the installation of the omnidirectional spraying component, it cannot guarantee that the movement will not result in directional rotation, thus causing uneven spraying. By installing a telescopic push rod, the position of the end limit bracket and positioning wheel can be adjusted. By adjusting the contact with the inside of the corridor, the overall trolley in the middle can be restricted. The positioning and moving component effectively avoids the problem of turning during movement. Attached Figure Description
