Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, in particular to a concrete curing equipment. Background Art

[0002] Concrete curing mainly includes the following two different meanings: first, the operation of sprinkling water or spraying plastic film on the cast-in-place concrete structure at the construction site; second, the steam curing of concrete bricks during the factory period. Generally, the first meaning is relatively more common, and it is also the application scenario of the curing equipment described in this utility model.

[0003] The common existing concrete watering and curing equipment mainly consists of a body, a water tank, a water pump, a water pipe, and a nozzle, so that the water can be sprayed as evenly as possible on the surface of the cast-in-place concrete structure, such as watering and curing the cast-in-place concrete floor slab.

[0004] Furthermore, a Chinese utility model patent with patent publication number CN220433653U and publication date 2024.02.02 discloses a high slope concrete sprinkling and maintenance device, which includes a mobile vehicle, and two support rods are arranged on the upper left side of the mobile vehicle, and a sprinkling and maintenance component for sprinkling water on the high slope concrete is arranged on the inner side of the top of the two support rods, and a water supply hose is connected to the front end of the sprinkling and maintenance component, and an angle adjustment component for adjusting the sprinkling angle is arranged between the sprinkling and maintenance component and the mobile vehicle, and a pressurizing component for adjusting the sprinkling pressure is installed at the lower middle part of the sprinkling and maintenance component.

[0005] The structural principle and advantages of the watering and maintenance device in this utility model patent are as follows: when the rubber tube is under pressure, the two rubber sheets inside it will also bend under pressure, thereby dividing the spray outlet into three spray outlets with smaller openings, further enhancing the water pressure, so that water can be sprayed to the highest point of the high slope, the watering is more uniform, and the maintenance of the high slope is more sufficient.

[0006] However, the watering maintenance device has at least the following two shortcomings in actual construction and use, which are also the technical problems to be solved by the utility model, namely:

[0007] 1. Its watering mode is fixed as "long-range high-speed spray" and "near-range low-speed spray", which cannot achieve the high-speed spray effect at a close distance, such as when garbage needs to be flushed nearby;

[0008] 2. The distance adjustment of the watering method is achieved through an electric telescopic rod, which will increase the structural complexity of the device, increase the cost, and increase the risk of water ingress and leakage.

[0009] So to sum up, there is an urgent need for a new type of sprinkler maintenance equipment in which the sprinkler distance and sprinkler speed are not bound together and the method of adjusting the sprinkler distance is simpler and more convenient, so as to be used in various concrete cast-in-place structures in construction.

[0010] The utility model provides a concrete curing device, which can be provided with a water tank, a water pump, a universal wheel, a manual rotating crossbar unit, a three-way valve-double nozzle unit, and a handle unit with holes on a bottom plate, so that:

[0011] 1. The water spray speed adjustment effect is achieved by using two nozzles with different water spray orifice sizes to ensure that the water spray distance and water spray speed are not bound and the two can be flexibly matched;

[0012] 2. The tilted water spraying action of the nozzle, its adjustment effect and fixing effect are all achieved through manual mechanical means, ensuring that the water spraying operation is relatively simple, and the cost and leakage risk of the equipment are reduced.

[0018] A further preferred technical solution is that the manual rotating cross rod unit further comprises a driving U-shaped plate which is arranged on the end surface of the transverse round rod close to the driving ring and is used to rotate the transverse round rod.

[0019] A further preferred technical solution is that the manual rotating crossbar unit further includes two rectangular grooves respectively arranged on two inner side surfaces of the driving U-shaped plate and used for engaging the right-angle trapezoidal block that has been taken out from the vertical rectangular hole.

DETAILED DESCRIPTION

[0035] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0036] As attached Figure 1-8 As shown, a concrete curing equipment comprises a base plate 11, a water tank 12, a water pump 13, and a universal wheel 14, and also comprises a manual rotating cross bar unit 1 arranged on the base plate 11, a three-way valve-double nozzle unit 2 arranged on the manual rotating cross bar unit 1 and connected to the water pump 13, and a handle unit 3 with holes arranged on the base plate 11, plugged and engaged with the manual rotating cross bar unit 1, and used to fix the inclination angle of the manual rotating cross bar unit 1.

[0037] In this embodiment, the water tank 12, the water pump 13 and the three-way valve-double nozzle unit 2 are connected in sequence, and the diameters of the water spray outlets of the two nozzles are "one large and one small", so that the maintenance equipment can provide two water spraying effects of "high speed and low speed", and in conjunction with the three-way valve, the two water spraying effects can be flexibly switched.

[0038] More importantly, the effect of rotating the manually rotating cross bar unit 1 to adjust the water spray inclination angle is independent of the above-mentioned water spray speed adjustment effect, so that when the maintenance equipment is spraying water toward a nearby distance, for example, it can still choose between the two water spray effects of "high speed and low speed". Conversely, when spraying water toward a distance, it is also equally flexible and optional.

[0039] Finally, the handle unit 3 with holes has at least the following functions:

[0040] First, as the force application part of the manual movement function of the maintenance equipment;

[0041] Second, the manual rotating crossbar unit 1 is engaged to prevent it from unnecessary lateral movement, so that it can only rotate to adjust the tilt angle of the water spraying action, that is, the pitch angle;

[0042] Third, when the manually rotating crossbar unit 1 has been adjusted to the desired tilt angle, it is fixed so that the tilt angle amplitude is not easily changed, thereby ensuring that the three-way valve-dual nozzle unit 2 can perform tilted water spraying operation as needed in a long-term and stable manner.

[0043] The manually rotating cross rod unit 1 includes a vertical plate 101 arranged on the bottom plate 11, a circular hole 102 arranged on the vertical plate 101, a transverse round rod 103 arranged on the circular hole 102 and used to install the three-way valve-double nozzle unit 2, and a driving ring 104 arranged on the transverse round rod 103 and engaged with the perforated handle unit 3 in the length direction of the transverse round rod 103 and used to receive the circumferential fixing effect of the perforated handle unit 3.

[0044] In this embodiment, the driving ring 104 is used to engage the perforated handle unit 3, so that the transverse rod 103 cannot be displaced in the direction of its own length. Thus, the transverse rod 103 and the two nozzles can be rotated and adjusted stably.

[0045] The three-way valve-double nozzle unit 2 includes a three-way valve 201 arranged on the water pump 13, two connecting hoses 202 respectively arranged on the two water outlet ends of the three-way valve 201, two straight pipes 203 arranged on the connecting hoses 202 and connected to the transverse round rods 103, and two nozzles 204 respectively arranged on the two straight pipes 203 and used for switching and adjusting the water spraying speed.

[0046] In this embodiment, the three-way valve 201 is a commercially available product, the connecting hose 202 is made of PVC steel wire tube, the straight tube 203 is made of hard plastic, and the two nozzles 204 have different water outlet sizes.

[0047] Therefore, the three-way valve 201 only needs to rotate and switch the effective water outlet, and the maintenance equipment can obtain two completely different water spraying effects of "high speed and low speed". The specific flow rate of the above water spraying effect is not limited, but only indicates that there is a significant difference between the flow rates.

[0048] The water outlets of the two nozzles 204 are both circular in shape, one of which has a diameter of 2.0-2.5 cm, and the other has a diameter of 0.5-1.0 cm.

[0049] In this embodiment, in order to balance the overall weight of the manual rotating crossbar unit 1, the two nozzles 204 and the two straight pipes 203 are respectively located on both sides of the vertical plate 101 in pairs, as shown in the attached figure. Figure 4 shown.

[0050] The perforated handle unit 3 includes a side vertical plate 301 arranged on the bottom plate 11, a horizontal connecting plate 302 arranged on the side vertical plate 301, a vertical rectangular hole 303 arranged on the horizontal connecting plate 302 and used to install the driving ring 104, a horizontal circular hole 304 arranged on the horizontal connecting plate 302 and used to pass the horizontal round rod 103, and a right-angled trapezoidal block 305 arranged on the vertical rectangular hole 303 and used to clamp and fix the driving ring 104.

[0051] In this embodiment, the main body of the handle unit 3 with holes is in an inverted U shape, and the width of the vertical rectangular hole 303 is slightly larger than the thickness of the driving ring 104, so that the manual rotating cross bar unit 1 is not easy to move and shake.

[0052] In addition, the transverse circular hole 304 passes through the transverse connecting plate 302 , which can be understood as: the transverse circular hole 304 is 2 or 2 sections, respectively located on both sides of the vertical rectangular hole 303 .

[0053] When installing the manual rotating cross bar unit 1, first align the driving ring 104 and the transverse circular hole 304 in the vertical rectangular hole 303, and then insert the transverse round rod 103 so that the end of the transverse round rod 103 on one side of the transverse connecting plate 302 is exposed.

[0054] Finally, the material of the right-angled trapezoidal block 305 is ordinary rubber. When the inclination angle of the straight tube 203 is adjusted to the required range, first hold and fix the horizontal round rod 103, and then insert the right-angled trapezoidal block 305 downward between the driving ring 104 and the inner side of the end of the vertical rectangular hole 303 until it is fully stuck. At this time, the horizontal round rod 103 is difficult to rotate anymore, and the grip can be released by hand.

[0055] When the right-angled trapezoidal block 305 is in use, its smaller end faces downward, that is, its inclined surface abuts against the driving ring 104 .

[0056] The manual rotating cross bar unit 1 further includes a driving U-shaped plate 105 which is arranged on the end surface of the transverse round bar 103 close to the driving ring 104 and is used to rotate the transverse round bar 103 .

[0057] In this embodiment, the transverse round rod 103 is first installed on the perforated handle unit 3, and the driving U-shaped plate 105 is then connected to the exposed end surface of the transverse round rod 103. The function of the driving U-shaped plate 105 is to make the rotation and fixing of the transverse round rod 103 relatively convenient without the need to directly hold it by hand.

[0058] The manual rotating crossbar unit 1 further includes two rectangular grooves 106 which are respectively arranged on two inner side surfaces of the driving U-shaped plate 105 and are used to engage the right-angle trapezoidal block 305 which has been taken out from the vertical rectangular hole 303 .

[0059] In this embodiment, one of the normal usage methods of the maintenance device is to let the nozzle 204 rotate up and down and spray water at the same time, and the right-angled trapezoidal block 305 is idle. Or when the maintenance device is stored and transported, the right-angled trapezoidal block 305 does not need to clamp the driving ring 104 and is also in an idle state.

[0060] At this time, the right-angled trapezoidal block 305 can be relatively slightly clamped on the two rectangular grooves 106 to prevent it from falling. The clamping strength at this time is much lower than the strength when it is clamped on the vertical rectangular hole 303 with the driving ring 104.

[0061] The manual rotating cross bar unit 1 also includes a radial snap-fitting groove 107 arranged on the annular surface of the driving ring 104 ; the perforated handle unit 3 also includes an inclination angle fixing plug rod 306 arranged on the transverse connecting plate 302 and used for inserting into the radial snap-fitting groove 107 .

[0062] In this embodiment, the engagement effect of the right-angled trapezoidal block 305 on the driving ring 104 can provide the nozzle 204 with a relatively unstable but steplessly adjustable tilt angle fixing effect.

[0063] The radial engaging groove 107 and the tilt angle fixing rod 306 are used together to provide a sufficiently stable but step-adjustable tilt angle fixing function for the nozzle 204. The above two functions have their own advantages and disadvantages, and one can be used.

[0064] The perforated handle unit 3 also includes an upward extension plate 307 arranged on the horizontal connecting plate 302, and a screw hole plate 308 arranged on the upward extension plate 307 and located above the driving ring 104 and used for screwing and installing the tilt angle fixing rod 306.

[0065] In this embodiment, the upwardly extending plate 307 and the screw hole plate 308 together form an "inverted L-shaped" structure, ensuring that the inclined angle fixing rod 306 is fully fixed to the transverse connecting plate 302. As long as the above-mentioned "inverted L-shaped" structure is not broken, the transverse connecting plate 302 can indirectly fix the inclined water spraying angle of the nozzle 204.

[0066] The perforated handle unit 3 further includes a connection rope 309 which is arranged on the transverse connection plate 302 and is used to connect the right-angle trapezoidal block 305 .

[0067] In this embodiment, the perforated handle unit 3 also includes a gripping sleeve 310 arranged on the transverse connecting plate 302. The gripping sleeve 310, the connecting rope 309 and the right-angled trapezoidal block 305 are integrally formed, so that the right-angled trapezoidal block 305 is not easy to fall off and the transverse connecting plate 302 is relatively more comfortable when gripped and pushed.

[0068] The three integrally formed parts are made of ordinary rubber, while the side vertical plates 301 and the horizontal connecting plate 302 are made of metal.

[0069] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
