Description

Technical Field

[0001] The present application relates to the technical field of concrete stamping construction, and in particular to an auxiliary stamping concrete construction device and a concrete stamping construction method. Background Art

[0002] Concrete stamping has a wide range of uses and can be applied to a variety of places such as municipal administration and urban construction. The cost of concrete stamping is generally only about 30%-50% of the cost of natural bricks and stones. It not only saves costs, but also reduces the mining of natural stones and wood, and reduces the damage to human natural resources. It is a modern green and environmentally friendly material that is conducive to the coordinated development of the environment, resources and economy.

[0003] At present, there is no clear construction process and construction quality acceptance standard for stamped concrete construction in the country. The construction effect of stamped concrete depends more on the experience and craftsmanship of the construction workers. Traditional stamped concrete construction is completed entirely by hand. After the concrete is poured, before the concrete is initially set, a strengthening agent is applied to the concrete surface. After the application is evenly applied, the concrete surface is smoothed and mold release powder is sprinkled. Then, the mold is placed on the concrete surface and manually tapped to press the mold. After the pressing is completed, the mold is moved and the above operation is repeated.

[0004] Therefore, during on-site construction, the embossing effect depends entirely on the embossing skills of the construction workers. The embossing process is time-consuming and labor-intensive, and there are many uncertainties in manual operation. During the construction process, it is very easy to have problems such as different depths of embossing marks on different plates, discontinuity between embossing patterns, and uneven embossing lines. In addition, when embossing a large area, multiple construction workers are required to work simultaneously, and the difference in experience levels of different construction workers will further amplify this problem. At the same time, when manually spreading the release powder, dust is easily generated due to manual throwing, and the uniformity of the application of the release powder is also difficult to control.

[0005] In view of this, according to actual needs, it is urgent to invent a tool that can be mass-produced and assist manual embossing, which can perform continuous embossing once to avoid the problem of discontinuous printing patterns caused by repeated manual movement of the mold; and can automatically apply a constant pressing force downward to replace the problem of unclear embossing patterns and uneven embossing effects caused by uneven force applied by manual pressing; and can also simultaneously perform uniform powder spreading before embossing to reduce the construction process and reduce dust pollution. Summary of the invention

[0014] Furthermore, the outlet pipe is arranged in a curved shape, and its inner arc side is arranged away from the embossing wheel.

[0015] Furthermore, the warehouse outlet pipe is made of metal material, and the straight-line distance between the free end of the warehouse outlet pipe and the storage bin is smaller than the straight-line distance between the stamping wheel and the storage bin.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1 and Figure 2 The present application discloses an auxiliary stamped concrete construction device, which includes: The storage bin 1 is closed, with a feeding port 11 at the top and a feeding port 12 at the bottom. In the specific configuration, the feeding port 11 and the feeding port 12 are not directly connected. The brush cylinder 2 is rotatably mounted in the storage bin 1 and is arranged corresponding to the material drop opening 12. Bristles 21 are arranged in an array on the arc-surface outer peripheral wall of the brush cylinder 2. The stamping wheel 3 is rotatably mounted below the storage bin 1; The stamping die 4 is detachably mounted and wrapped around the arc-surface outer peripheral wall of the stamping wheel 3; The excitation mechanism 5 is disposed in the embossing wheel 3 and is used to apply a vertical downward excitation force to the embossing wheel 3, and is specifically configured as a vibration motor with a vibration direction in a vertical plane; An outlet pipe 6, one end of which is connected to the blanking opening 12 on the storage bin 1, and the other end of which extends away from the storage bin 1; and The transmission mechanism is used to realize the rotation of the brush cylinder 2 when the embossing wheel 3 rotates; specifically, when the storage bin 1 moves along the arrangement direction of the embossing wheel 3 and the outlet pipe 6, the brush cylinder 2 rotates to transport the demoulding powder in the storage bin 1 to the blanking port 12; otherwise, the demoulding powder at the blanking port 12 is transported to the storage bin 1.

[0023] In this way, when it is necessary to perform stamping construction on the concrete pavement, first install the corresponding stamping mold 4 on the stamping wheel 3 to ensure that the stamping mold 4 completely covers the curved outer peripheral wall of the stamping wheel 3, add an appropriate amount of demoulding powder into the storage bin 1, and then transfer the construction device of the present application to the concrete pavement to be stamped. The operator stands on the side of the storage bin 1 where the outlet pipe 6 is set, and pulls the storage bin 1 to move at a uniform speed along the arrangement direction of the stamping wheel 3 and the outlet pipe 6; at the same time, the vibration mechanism 5 is also turned on.

[0024] In this way, the embossing wheel 3 can drive the brush cylinder 2 to rotate with the help of the transmission mechanism when rotating. The brush cylinder 2 sweeps the demoulding powder in the storage bin 1 and transports it to the material outlet 12 when rotating, and spreads it on the concrete floor after being guided by the outlet pipe 6, which can improve the uniformity of powder spreading, and at the same time, it can also prevent the demoulding powder that has been placed for a long time from hardening and affecting the powder spreading effect to a certain extent. Then, when the embossing wheel 3 moves to the road surface spread with demoulding powder, the embossing die 4 set thereon can emboss a preset pattern on the concrete road surface, and with the help of the excitation effect of the excitation mechanism 5, a stable downward pressure can be applied to the embossing die 4, which can effectively ensure the consistency of the depth of the embossing effect and the obviousness of the pattern; and the oscillation effect of the excitation mechanism 5 will also be transmitted to the storage bin 1, which can oscillate the demoulding powder contained in the storage bin 1, which can further reduce the probability of hardening of the demoulding powder in the storage bin 1. When the storage bin 1 is continuously pulled, a continuous pattern can be embossed on the concrete pavement by means of the rolling of the embossing wheel 3, thereby ensuring the construction quality.

[0025] Therefore, through the construction device of the present application, a continuous stamping on the concrete pavement can be achieved, which can avoid the problem of discontinuous printing patterns caused by repeated manual movement of the mold; and with the help of the excitation mechanism 5, a constant stamping force can be automatically applied downward to solve the problem of unclear stamping patterns and uneven stamping effects caused by uneven force applied by manual stamping; it can also simultaneously carry out uniform powder spreading before stamping to reduce the construction process and reduce dust pollution; and with the help of the construction device of the present application, only one operator is needed to complete the concrete stamping operation. Compared with the conventional technology that requires multiple construction personnel to work together, it greatly saves manpower, reduces construction costs, and has significant economic benefits.

[0026] In addition, when the construction device of the present application moves to an area of ​​the concrete pavement to be imprinted and is completed, the storage bin 1 is pushed in the direction opposite to the arrangement direction of the imprinting wheel 3 and the outlet pipe 6 to transfer the construction device to the next area; in this process, under the action of the transmission mechanism, the brush cylinder 2 rotates in the opposite direction, and the demolding powder at the drop port 12 can be transported to the storage bin 1, so as to achieve the effect that the demolding powder in the storage bin 1 will not be spread during the transfer of the construction device, which greatly improves the convenience of using the present application.

[0027] Specifically, refer to Figure 1 and Figure 3 The above-mentioned embossing wheel 3 comprises: The fixed cylinder 31 is fixedly installed below the storage bin 1, the excitation mechanism 5 is installed in the fixed cylinder 31, and brackets 15 are fixedly connected to the bottom of both sides of the storage bin 1, and the two ends of the fixed cylinder 31 are respectively fixed to the two brackets 15; The embossing cylinder 32 is coaxially rotatably installed on the outer periphery of the fixed cylinder 31, and the embossing die 4 is installed on the outer periphery of the embossing cylinder 32; specifically, the embossing die 4 can be bolted and fixed on the curved outer peripheral wall of the printing cylinder, and both ends of the embossing cylinder 32 are coaxially fixed with convex rings for limiting the lateral movement of the embossing die 4 and positioning the embossing die 4. The radial thickness of the convex ring is smaller than the thickness of the embossing die 4 to avoid marks during embossing.

[0028] In addition, a handlebar 13 extending obliquely upward is installed at the end of the fixed cylinder 31 or the storage bin 1. In the present embodiment, the handlebar 13 is installed at the end of the fixed cylinder 31 to facilitate the operator to hold it.

[0029] In addition, the above-mentioned transmission mechanism includes: The first transmission wheel 71 is coaxially fixed to one end of the stamping cylinder 32, and the end of the stamping cylinder 32 is flush with the outer wall of the storage bin 1, and the length of the fixed cylinder 31 is greater than the width of the storage bin 1; The second transmission wheel 72 is rotatably mounted on the outer wall of the storage bin 1, and the second transmission wheel 72 is connected to the first transmission wheel 71 in the same direction. Specifically, the transmission can be carried out by means of a belt or a synchronous wheel, synchronous belt, sprocket chain, etc., and the belt, synchronous belt, chain, etc. used for transmission penetrates the bracket 15 on the storage bin 1 and connects the first transmission wheel 71 and the second transmission wheel 72; A first gear 73 is coaxially mounted on the end of the brush tube 2. Specifically, a fixed shaft extending outside the storage bin 1 is fixedly connected to the end of the brush tube 2, and the first gear 73 is coaxially fixedly connected to the fixed shaft; and The second gear 74 is coaxially fixed to the second transmission wheel 72 , and the second gear 74 is meshingly connected with the first gear 73 .

[0030] In this way, when the operator pulls the handrail 13, the storage bin 1 moves along the arrangement direction of the embossing wheel 3 and the outlet pipe 6. At this time, the embossing cylinder 32 drives the second transmission wheel 72 to rotate through the first transmission wheel 71 when rotating. When the second transmission wheel 72 rotates, it drives the brush cylinder 2 to rotate in the opposite direction with the help of the meshing transmission effect of the second gear 74 and the first gear 73. At this time, the demoulding powder in the storage bin 1 is swept toward the blanking port 12 by the bristles 21 on the brush cylinder 2; conversely, when the operator pushes the handrail 13, the storage bin 1 moves in the direction opposite to the arrangement direction of the embossing wheel 3 and the outlet pipe 6. At this time, the brush cylinder 2 rotates to transport the demoulding powder at the blanking port 12 to the storage bin 1, so as to prevent the demoulding powder from falling from the blanking port 12 when the construction device of the present application needs to be transferred.

[0031] Further, in order to improve the convenience of use of the construction device of this application, refer to Figure 1 and Figure 2 , the inner bottom wall of the storage bin 1 is inclined, and the end close to the blanking port 12 is lower than the end away from the blanking port 12, so that the demoulding powder in the storage bin 1 has a tendency to slide toward the blanking port 12, so as to ensure the continuity of the powder falling from the blanking port 12. A baffle 14 is arranged around the outer periphery of the brush cylinder 2 in the storage bin 1, the feeding port 11 is arranged above the brush cylinder 2, the baffle 14 separates the feeding port 11 and the brush cylinder 2, and a transition curved surface 141 is arranged on the side of the baffle 14 facing the feeding port 11; in this way, it is convenient to put demoulding powder into the storage bin 1, and the probability of dust generation when the brush cylinder 2 is rotating to sweep the powder can be reduced. In addition, the arrangement of the baffle 14 can also prevent the demoulding powder from excessively covering the bristles 21 of the brush cylinder 2 and affecting the rotation and the amount of powder spread.

[0032] In addition, the outlet pipe 6 is arranged in a curved shape, and its inner arc side is arranged away from the stamping wheel 3, which can appropriately increase the sliding stroke of the demoulding powder in the outlet pipe 6, so that the demoulding powder is spread as much as possible, so as to ensure the uniformity of the spreading of the demoulding powder on the concrete pavement. Moreover, the outlet pipe 6 is made of metal material, and the straight-line distance between the free end of the outlet pipe 6 and the storage bin 1 is less than the straight-line distance between the stamping wheel 3 and the storage bin 1, so that when the construction device stops working, the outlet pipe 6 can be used as a support to facilitate the parking of the construction device.

[0033] The present application also discloses a concrete stamping construction method, which is based on the above-mentioned auxiliary stamping concrete construction device and adopts the following technical solution: A concrete stamping construction method comprises the following steps: S1. The desired embossing pattern is mounted on the outer periphery of the embossing wheel 3 by the embossing mold 4, ensuring that the embossing mold 4 completely covers the curved outer peripheral wall of the embossing cylinder 32 in the embossing wheel 3; S2. Add release powder to the storage bin 1; S3. The construction device of the present application is transferred to the concrete pavement to be stamped, the vibration mechanism 5 is started, and the storage bin 1 is pulled to continuously move in the direction where the operator stands, and the brush cylinder 2 is driven by the transmission mechanism to rotate to transport the demoulding powder in the storage bin 1 to the outlet pipe 6, and then the powder falls from the bottom of the outlet pipe 6 and is spread on the concrete pavement; the stamping wheel 3 stamps the concrete pavement after the powder is sprinkled while rotating, and the stamping quality is ensured under the action of the vibration mechanism 5; S4. After one area of ​​the concrete pavement to be stamped is stamped, the storage bin 1 is pushed away from the operator standing to transfer the construction device to the next area, and step S3 is repeated until all areas are stamped.

[0034] The implementation principle of an auxiliary stamped concrete construction device in the embodiment of the present application is: When it is necessary to perform stamping construction on the concrete pavement, first install the corresponding stamping mold 4 on the stamping cylinder 32 of the stamping wheel 3, ensure that the stamping mold 4 completely covers the curved outer peripheral wall of the stamping cylinder 32, add a proper amount of demoulding powder into the storage bin 1, and then transfer the construction device of the present application to the concrete pavement to be stamped. The operator stands on the side of the storage bin 1 where the outlet pipe 6 is set, and pulls the storage bin 1 to move at a uniform speed along the arrangement direction of the stamping wheel 3 and the outlet pipe 6; at the same time, the vibration mechanism 5 is also turned on.

[0035] In this way, the embossing wheel 3 can drive the brush cylinder 2 to rotate in the opposite direction when rotating. The brush cylinder 2 sweeps the demoulding powder in the storage bin 1 and transports it to the material outlet 12 when rotating, and spreads it on the concrete floor after being guided by the outlet pipe 6, which can improve the uniformity of powder spreading, and at the same time, it can also prevent the demoulding powder that has been placed for a long time from hardening and affecting the powder spreading effect to a certain extent. Then, when the embossing wheel 3 moves to the road surface spread with demoulding powder, the embossing die 4 set thereon can emboss a preset pattern on the concrete road surface, and with the help of the excitation effect of the excitation mechanism 5, a stable downward pressure can be applied to the embossing die 4, which can effectively ensure the consistency of the depth of the embossing effect and the obviousness of the pattern; and the oscillation effect of the excitation mechanism 5 will also be transmitted to the storage bin 1, which can oscillate the demoulding powder contained in the storage bin 1, which can further reduce the probability of hardening of the demoulding powder in the storage bin 1. When the storage bin 1 is continuously pulled, a continuous pattern can be embossed on the concrete pavement by means of the rolling of the embossing wheel 3, thereby ensuring the construction quality.

[0036] When an area of ​​the concrete pavement to be stamped is completed, the storage bin 1 is pushed in the direction opposite to the arrangement direction of the stamping wheel 3 and the outlet pipe 6 to transfer the construction device to the next area; during this process, the brush cylinder 2 can transport the demoulding powder at the drop port 12 to the storage bin 1 when it rotates, so as to achieve the effect that the demoulding powder in the storage bin 1 will not be spread during the transfer of the construction device, which greatly improves the convenience of using the present application.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
