Description

Technical Field

[0001] This utility model relates to the field of sand box technology, and in particular to a novel sand box with a cooling function. Background Technology

[0002] Sand boxes are equipment used in the construction of cast-in-place beams with steel pipe pile supports. They are used for unloading during the construction of cast-in-place beams with steel pipe pile supports. After the steel pipe pile support Bailey beam is erected, the construction of the cast-in-place beam begins. After the cast-in-place beam construction is completed, the support needs to be dismantled. When dismantling the support, sand boxes are placed between the steel pipe piles and the distribution beams. By filling them with sand, the sand boxes can provide stable support force, ensuring that the beams and slabs will not deform or collapse due to their own weight or other external forces during construction. They play an important role in building construction.

[0003] Sand boxes are mostly used outdoors, making them susceptible to the influence of external ambient temperature. In particular, sand has low thermal conductivity, and under strong sunlight and high ambient temperature, steel sand boxes are prone to causing the sand inside to heat up. Once heated, the sand cannot dissipate easily, which can affect the solidification speed and effect of the steel pipe pile supports being poured inside due to high temperature. Existing sand boxes generally do not have a cooling function. Therefore, we propose a new type of sand box with a cooling function. Utility Model Content

[0004] The problem this invention aims to solve is that existing sandboxes lack cooling functions, making it difficult to cool down after prolonged exposure to sunlight when used outdoors.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel sand box with cooling function, comprising a sand cylinder and a sealing base plate. The sealing base plate is welded and fixed to the bottom surface of the sand cylinder, and a water tank sleeve is welded and fixed to the outer surface of the sand cylinder. The bottom surface of the water tank sleeve is welded and fixed to the top surface of the sealing base plate. A water storage cavity is formed between the inside of the water tank sleeve and the outer surface of the sand cylinder. A sand discharge pipe is fixed through the outer surface of the sand cylinder. A one-way valve is installed at one end of the sand discharge pipe extending to the outside of the water tank sleeve. A water inlet pipe is fixed through the upper end of one side of the water tank sleeve, and a drain pipe is fixed through the lower end of the other side of the water tank sleeve.

[0006] As a preferred embodiment of the novel sand box with cooling function described in this utility model, wherein: the outer surface of the water tank sleeve is wrapped and fixed with a heat insulation cotton sleeve, the outer surface of the heat insulation cotton sleeve is coated with a heat insulation coating, and the height of the heat insulation cotton sleeve is equal to the height of the water tank sleeve.

[0007] As a preferred embodiment of the novel sand box with cooling function described in this utility model, the top surface of the water tank sleeve is rotatably connected to a support pipe via a bearing, a support plate is fixed to the top surface of the support pipe, a detachable support rod is fixed to the support plate, the support rod is inserted inside the sand cylinder, a number of stirring rods are equidistantly fixed to the side of the support rod facing the center of the sand cylinder, and a number of gripping rods are equidistantly fixed to the outer surface of the support pipe.

[0008] As a preferred embodiment of the novel sand box with cooling function described in this utility model, wherein: another one-way valve is installed on both the water inlet pipe and the water outlet pipe, and through holes that cooperate with the water inlet pipe and the water outlet pipe are respectively opened at the upper and lower ends of both sides of the water tank sleeve.

[0009] In a preferred embodiment of the novel sand box with cooling function described in this utility model, the inner diameter of the support plate is larger than the outer diameter of the sand cylinder, and the outer diameter of the support plate is smaller than the outer diameter of the water tank sleeve.

[0010] As a preferred embodiment of the novel sand box with cooling function described in this utility model, wherein: a support screw is fixed on the top surface of the support plate, a fixing plate is rotatably sleeved on the support screw, a nut is threaded on the support screw on the top surface of the fixing plate, a fixing block is fixed on the top surface of the support rod, a fixing screw is fixed on the top surface of the fixing block, a fixing groove is opened at the end of the fixing plate away from the support screw to cooperate with the fixing block and the fixing screw, and a nut is threaded on the end of the fixing screw extending above the fixing plate.

[0011] In a preferred embodiment of the novel sand box with cooling function described in this utility model, the fixing groove is configured as a rectangle that cooperates with the fixing block, the thickness of the fixing block is less than the thickness of the fixing groove, and the width of the top of the support rod is greater than the width of the fixing groove.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a wrap-around water storage chamber. During pouring, when the external temperature is too high or too low and affects solidification, cold or hot water is poured into the water storage chamber to control the temperature of the sand inside, thereby ensuring the stability of the internal temperature of the sand cylinder. This solves the problem that existing sand boxes do not have a cooling function, which makes it inconvenient to cool down after prolonged exposure to the sun when used outdoors. In addition, the sand is stirred by a stirring rod, which avoids the problem of insufficient sand discharge when the sand is not dry enough, ensuring that the sand can be discharged quickly and improving the practicality of the sand box.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1-4 This embodiment is a novel sand box with cooling function, including a sand cylinder 1 and a sealing base plate 2. The sealing base plate 2 is welded and fixed to the bottom surface of the sand cylinder 1. A water tank sleeve 3 is welded and fixed to the outer surface of the sand cylinder 1. The bottom surface of the water tank sleeve 3 is welded and fixed to the top surface of the sealing base plate 2. A water storage cavity 4 is formed inside the water tank sleeve 3 and on the outer surface of the sand cylinder 1. A sand discharge pipe 7 is fixed through the outer surface of the sand cylinder 1. A one-way valve 8 is installed at one end of the sand discharge pipe 7 extending to the outside of the water tank sleeve 3. A water inlet pipe 9 is fixed through the upper end of one side of the water tank sleeve 3. A drain pipe 10 is fixed through the lower end of the other side of the water tank sleeve 3.

[0020] In this embodiment, the outer surface of the water tank sleeve 3 is wrapped and fixed with a thermal insulation cotton sleeve 5. The outer surface of the thermal insulation cotton sleeve 5 is coated with a heat insulation coating 6. The heat insulation coating 6 contains low thermal conductivity materials and specific resins, which can effectively resist heat transfer. The thermal insulation cotton sleeve 5 and the heat insulation coating 6 work together to improve the heat insulation effect of the outer surface of the water tank sleeve 3. After the water storage chamber 4 is filled with cold or hot water, it is convenient to control the temperature of the sand inside the sand cylinder 1, and to facilitate the cooling or heat preservation of the sand. The height of the thermal insulation cotton sleeve 5 is equal to the height of the water tank sleeve 3.

[0021] In this embodiment, a support pipe 11 is rotatably connected to the top surface of the water tank sleeve 3 via a bearing. A support plate 12 is fixed to the top surface of the support pipe 11. The inner diameter of the support plate 12 is larger than the outer diameter of the sand cylinder 1, and the outer diameter of the support plate 12 is smaller than the outer diameter of the water tank sleeve 3, so as to avoid the support plate 12 affecting the normal use of the sand cylinder 1. A detachable support rod 13 is fixed on the support plate 12. The support rod 13 is inserted into the sand cylinder 1. Several stirring rods 14 are fixed at equal intervals on the side of the support rod 13 facing the center of the sand cylinder 1. When the sand inside the sand cylinder 1 is compacted under force and the sand itself is not dry enough, the sand is stirred by the support rod 13 and the stirring rods 14. When the support is removed, the sand can be loosened by stirring, which facilitates the discharge of the sand. Several gripping rods 15 are fixed at equal intervals on the outer surface of the support pipe 11.

[0022] In this embodiment, another one-way valve 8 is installed on both the inlet pipe 9 and the outlet pipe 10. When using the sand box, the inlet pipe 9 and the outlet pipe 10 are connected by water pipes respectively, and the inlet pipe 9 is connected to the outlet of the water tank by water pipes, and the outlet pipe 10 is connected to the inlet of the wastewater tank. The upper and lower ends of both sides of the water tank sleeve 3 are respectively provided with through holes that cooperate with the inlet pipe 9 and the outlet pipe 10.

[0023] In this embodiment, a support screw 16 is fixed on the top surface of the support plate 12, and a fixing plate 17 is rotatably sleeved on the support screw 16. A nut is threaded onto the support screw 16 on the top surface of the fixing plate 17. A fixing block 18 is fixed on the top surface of the support rod 13, and a fixing screw 19 is fixed on the top surface of the fixing block 18. A fixing groove 20 that mates with the fixing block 18 and the fixing screw 19 is opened at the end of the fixing plate 17 away from the support screw 16. A nut is threaded onto the end of the fixing screw 19 that extends above the fixing plate 17. By fixing and releasing the support rod 13 and the support plate 12, the support rod 13 and the stirring rod 14 are removed from the inside of the sand cylinder 1, and the fixing plate 17 is rotated to be removed above the sand cylinder 1 to avoid affecting the utilization of the internal space of the sand cylinder 1.

[0024] In this embodiment, the fixing groove 20 is set as a rectangle that cooperates with the fixing block 18 to prevent the support rod 13 from rotating inside the fixing plate 17, thereby preventing the stirring rod 14 from rotating to the inner wall of the sand cylinder 1. The thickness of the fixing block 18 is less than the thickness of the fixing groove 20, and the width of the top of the support rod 13 is greater than the width of the fixing groove 20.

[0025] Working principle: When sand cylinder 1 is needed, first connect the inlet pipe 9 and the outlet pipe 10 to the temperature-controlled water tank and wastewater tank respectively. When temperature control of the sand inside sand cylinder 1 is required, open the one-way valve 8 on the inlet pipe 9 to add cold or hot water for temperature control into the water storage chamber 4. After the water storage chamber 4 is filled with cold or hot water, open the one-way valve 8 on the outlet pipe 10 to discharge the temperature-controlled wastewater. Then, add water to the water storage chamber 4 as needed for cooling or heating. When the support needs to be removed to discharge sand, open the one-way valve 8 on the sand discharge pipe 7 to discharge the sand inside sand cylinder 1. When the sand inside sand cylinder 1 clumps or accumulates and discharges poorly, tighten the nut so that the nut is in contact with the fixing plate. Release the fixing plate 17, rotate the fixing plate 17, rotate the fixing groove 20 to the top of the sand cylinder 1, and then tighten the nut to fix the fixing plate 17. Insert the support rod 13 and the stirring rod 14 into the sand cylinder 1, and then insert the fixing screw 19 into the fixing groove 20. Fix the support rod 13 to the fixing plate 17 with the nut. After fixing, hold the handle 15 to drive the support tube 11 to rotate. The support tube 11 drives the support plate 12 to rotate. When the support plate 12 rotates, it drives the support rod 13 and the stirring rod 14 to make a circular motion inside, stirring and loosening the sand inside the sand cylinder 1. After the sand is discharged, tighten the nut again to take out the support rod 13 and the stirring rod 14, and tighten the nut to rotate the fixing plate 17 to the top of the removed sand cylinder 1.
