Description

Technical Field

[0001] This utility model relates to the field of precast beam spray curing technology, and in particular to a precast beam spray curing system. Background Technology

[0002] Precast beams are widely used in highway engineering because they have advantages such as standardized production, high construction efficiency, controllable quality, and minimal environmental impact. They meet the needs of current infrastructure construction and have become an important component in modern bridge and road construction, providing strong support for the high-quality development of highway engineering.

[0003] Precast beam curing is a process that involves controlling temperature and humidity within a specific timeframe after concrete pouring to ensure sufficient hydration and thus guarantee concrete strength and durability. Inadequate curing can lead to serious consequences, including insufficient strength, cracking, decreased durability, and increased deformation. These problems not only affect project quality and safety but also increase economic costs and maintenance difficulties. Currently, automatic sprinkler curing systems combined with geotextile coverings are commonly used in construction to maintain the components in a moist state. However, conventional automatic sprinkler systems suffer from problems such as incomplete spraying, complex supporting systems, low turnover rate, high cost, limited application scenarios, and complex piping installations. Furthermore, they are prone to damage during cross-process operations, resulting in high maintenance and repair costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a convenient spray curing system for precast beams.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A precast beam spray curing system includes a gantry crane, a frame detachably connected to one of the support frames of the gantry crane, a support frame rotatably connected to the frame, a water tank fixed to the gantry crane, a booster pump connected to the water tank via a pipe, and a spray section connected to the booster pump via a hose; the spray section is fixedly connected to the bottom of the support frame.

[0007] Furthermore, the support frame includes a cantilever beam and several connectors fixed below the cantilever beam for fixing the spray unit; an upper fixing plate and a lower fixing plate are fixedly connected to the frame; one end of the cantilever beam is located in the space between the upper fixing plate and the lower fixing plate; the cantilever beam is rotatably connected to the upper fixing plate and the lower fixing plate by a pin; when spraying maintenance is performed, the cantilever beam is arranged parallel to the upper fixing plate and the lower fixing plate, and the three are kept fixed by fasteners; when the support frame is stored, the cantilever beam is rotated to be perpendicular to the upper fixing plate and the lower fixing plate.

[0008] Furthermore, an upper diagonal brace is fixedly connected to the upper end of the cantilever beam near the frame; the upper end of the upper diagonal brace is rotatably connected to the frame; a lower diagonal brace is fixedly connected to the lower end of the cantilever beam near the frame; the lower end of the lower diagonal brace is rotatably connected to the frame.

[0009] Furthermore, the frame is provided with a clamping plate for fixing the cantilever beam when the support frame is stored; the clamping plate has a "U" shaped cross section.

[0010] Furthermore, the spraying section includes a transverse spray pipe and a vertical spray pipe connected to both ends of the transverse spray pipe; the transverse spray pipe and the vertical spray pipe are provided with a number of water holes for spraying and curing the precast beam; and the water holes are connected to nozzles.

[0011] Furthermore, the overall lateral length of the support frame is less than the width of the gantry crane.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a frame and a support frame, the support frame can rotate relative to the gantry crane. During operation, it rotates to a position perpendicular to the frame to spray and cure the precast beams, effectively improving the uniformity and coverage of concrete curing. When not in operation, the support frame can be rotated to a position parallel to the frame for storage, ensuring that the support frame does not affect other functions of the gantry crane or the passage of vehicles on site. The support frame and the spray unit are directly attached to the gantry crane, eliminating the need for additional tracks or fixing devices. It is easy to install, stable, and reliable when used in conjunction with the gantry crane. Compared with conventional methods, it saves more manpower and resources, and its manufacturing and operating costs are also lower. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] A precast beam spray curing system, referring to Figure 1-5 As shown, it includes a gantry crane 1, a frame 2 detachably connected to one of the support frames of the gantry crane 1, a support frame 3 rotatably connected to the frame 2, a water tank 4 fixed to the gantry crane 1, a booster pump 5 connected to the water tank 4 by a pipe, and a spray section 6 connected to the booster pump 5 by a hose; the spray section 6 is fixed to the bottom of the support frame 3.

[0025] It should be noted that the gantry crane 1 is a hoisting machine used at the precast beam fabrication site, which can lift the precast beam during transportation; the frame 2 facilitates the installation of other components; the support frame 3 facilitates the support of the spray unit 6 and can rotate relative to the gantry crane 1 and the frame 2; the water tank 4 provides sufficient water for curing; the booster pump 5 can increase the water pressure to facilitate spraying, and those skilled in the art can reasonably select the model of the booster pump 5 according to the actual situation; the spray unit 6 can spray the precast beam 8 located on the base 7.

[0026] Specifically, the support frame 3 includes a cantilever beam 31 and several connectors 36 fixed below the cantilever beam 31 for fixing the spray unit 6; an upper fixing plate 21 and a lower fixing plate 22 are fixedly connected to the frame 2; one end of the cantilever beam 31 is located in the space between the upper fixing plate 21 and the lower fixing plate 22; the cantilever beam 31 is rotatably connected to the upper fixing plate 21 and the lower fixing plate 22 by a pin 33; when spraying maintenance is performed, the cantilever beam 31 is arranged parallel to the upper fixing plate 21 and the lower fixing plate 22, and the three are kept fixed by the fasteners 32; when the support frame 3 is stored, the cantilever beam 31 is rotated to be perpendicular to the upper fixing plate 21 and the lower fixing plate 22. The cantilever beam 31 is the main component supporting the spray unit 6; the connector 36 can facilitate the fixing of the spray unit 6; the upper fixing plate 21 and the lower fixing plate 22 can form a receiving space, in which one end of the cantilever beam 31 can be placed, and the cantilever beam 31 can be rotated by the pin 33; during operation, the cantilever beam 31 does not rotate with the upper fixing plate 21 and the lower fixing plate 22 by the reconnector 32, thus ensuring that the cantilever beam 31 is fixed during the movement of the gantry crane 1.

[0027] To ensure the stable connection of the cantilever beam 31, an upper diagonal brace 34 is fixedly connected to the upper end of the cantilever beam 31 near the frame 2; a lower diagonal brace 35 is fixedly connected to the lower end of the cantilever beam 31 near the frame 2. The upper end of the upper diagonal brace 34 and the lower end of the lower diagonal brace 35 are rotatably connected to the frame 2, ensuring convenient movement of the support frame 3 as a whole. The support frame 3 can rotate 180°, and the cantilever beam 31 is made of 10# channel steel, which facilitates rotation and ensures sufficient strength.

[0028] To facilitate other lifting operations of the gantry crane 1, such as ensuring unimpeded transport of the precast beam 8, the frame 2 is equipped with a clamping plate 23 for securing the cantilever beam 31 when the support frame 3 is stowed; the clamping plate 23 has a U-shaped cross-section. The clamping plate 23 facilitates the fixing of the support frame 3, making the gantry crane's lifting operations easier.

[0029] Specifically, the spraying unit 6 includes a transverse spray pipe 61 and a vertical spray pipe 62 connected to both ends of the transverse spray pipe 61. Several water holes for spraying and curing the precast beam are provided on the transverse spray pipe 61 and the vertical spray pipe 62; nozzles 63 are connected to the water holes. The transverse spray pipe 61 and the vertical spray pipe 62 can effectively spray and cure the precast beam 8; the nozzles 63 ensure a more uniform water flow during spraying and curing. The transverse spray pipe 61 and the vertical spray pipe 62 are made of hollow steel pipes with a diameter of 50mm. The spacing between any two water holes on the transverse spray pipe 61 and the vertical spray pipe 62 is 300mm, and the hole diameter is 5mm, enabling full coverage curing of the beam. The transverse spray pipe 61 and the vertical spray pipe 62 are welded to ensure sufficient strength.

[0030] In this application, the overall lateral length of the support frame 3 is less than the width of the gantry crane 1 to prevent the rotation of the support frame 3 from being restricted.

[0031] The working principle of this utility model:

[0032] During operation, the support frame 3 is rotated to a position parallel to the crossbeam of the gantry crane 1. Then, the support frame 3 is fixed to the upper fixed plate 21 and the lower fixed plate 22 via the connector 32. Water in the water tank 4 is pressurized by the booster pump 5 and sprayed through the horizontal spray pipes 61 and vertical spray pipes 62 on the spray section 6, effectively providing all-around spray curing to the precast beam 8 located between the horizontal spray pipe 61 and the two vertical spray pipes 62. Moving the gantry crane 1 further ensures a more thorough spray curing process. After the work is completed, the gantry crane 1 is moved... The gantry crane 1 is moved to the predetermined position, and then the connecting piece 32 is disassembled, so that the support frame 3 can rotate with the upper fixed plate 21 and the lower fixed plate 22. By rotating the support frame 3 to a position parallel to the frame 2, the spraying part 6 can also be rotated to a position parallel to the frame 2. The support frame 3 is fixed by the clamping plate 23, ensuring that the support frame 3 does not affect the use of other functions of the gantry crane 1 or the passage of vehicles on site. No additional track or fixing device is required. Compared with the conventional method, it saves more manpower and material resources, and its manufacturing and use costs are also lower.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
