Description

Technical Field

[0001] The invention relates to the field of civil construction, and in particular to an automatic foundation-building device for curbstones. Background Art

[0002] After the installation of the curbstone is completed, it is often necessary to strengthen the support with a backrest on the side of the curbstone away from the road surface to keep the installation of the curbstone stable. One of the ways to form the curbstone backrest is to use cast-in-place concrete. In order to facilitate on-site construction and reduce the process of supporting the formwork, a mobile side formwork forming device is currently used for construction, such as a curbstone backrest forming machine disclosed in application number 202323070242.1, which sets a support for contact on the side of the curbstone facing the road surface, sets a template 4 on the back side of the curbstone, puts concrete (generally low-fluidity concrete that can be quickly formed) between the curbstone and the template 4, and then the on-site staff compacts and levels the concrete through the pressure rod of the pressure plate set at the bottom to complete the backrest forming of the current stage, and then drags the support and template 4 forward to carry out the next stage of forming.

[0003] After the concrete is placed in this type of existing forming device, it is necessary to manually press down the top surface of the concrete repeatedly to compact and level the concrete, which results in high labor intensity. In addition, since low-fluidity concrete is often prone to air pockets inside the concrete when it is placed, it is difficult to achieve uniform manual compaction, resulting in accumulation of air pockets inside the concrete due to light compaction in some stages, and a short service life.

[0004] Based on this, the applicant proposed an automatic curbstone foundation device to solve the problems existing in the prior art. Summary of the invention

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In the present invention, Figure 1-5 As shown, an automatic kerbstone foundation device is provided, comprising: a bracket assembly, the bracket assembly comprising an outer bracket 1, an inner bracket 2, an upper bracket 3 connected to the outer bracket 1 and the top of the inner bracket 2, the outer bracket 1 can be against the side of the kerbstone, the inner bracket 2 comprises a vertically extending template 4, the upper bracket 3 comprises an upper rail 5 that can extend along the length direction of the kerbstone, and the bottom of the upper bracket 3 is provided with a support wheel 6 that can be supported on the top surface of the kerbstone; a scraper plate 7 assembly, comprising a scraper plate 7 slidably mounted on the upper rail 5, the The scraper plate 7 can extend between the curbstone and the template 4; the flat top assembly includes a driving part slidably arranged on the upper rail 5, a first flat top plate 8 and a second flat top plate 9 connected to the driving part, the first flat top plate 8 is arranged on the side of the second flat top plate 9 facing the scraper plate 7, and the driving part can drive the first flat top plate 8 and the second flat top plate 9 to move up and down respectively, wherein the lower limit of movement of the first flat top plate 8 is higher than the lower limit of movement of the second flat top plate 9, and the width of the first flat top plate 8 is smaller than the width of the second flat top plate 9.

[0029] When the foundation-building device of the present invention is used, the template 4 is placed on the back side of the curbstone, and the outer bracket 1 is abutted against the other side of the curbstone, and then concrete is placed between the curbstone and the template 4, so that the top surface of the concrete is roughly located in the set height range (higher than the top surface of the backrest after molding), and a marking line can be set on the inner side of the template 4 as a reference. Then the scraper plate 7 assembly and the flat top assembly are moved, and the lower edge of the scraper is located in the aforementioned set height range to further scrape the top surface of the concrete flat. During the movement of the flat top assembly, the driving unit drives the first flat top plate 8 to move up and down first and impact the bottom concrete to initially reduce the height of the concrete and disperse the air bags in the concrete. Since the width of the first flat top plate 8 is small, the air bags diffused to the upper side of the concrete are easy to escape after being dispersed, so as to increase the strength of the upper section of the backrest after molding and reduce the possibility of cracking and damage to the top of the backrest. Moreover, the width of the first flat top plate 8 is small, which can also reduce the impact force of the first flat top plate 8 on the driving unit when it is slapped downward, and then the actual slapping stroke of the first flat top plate 8 can be increased. When the second flat top plate 9 taps the area that has been tapped by the first flat top plate 8, the top surface of the concrete can be further leveled, making the top surface of the concrete more level and smooth.

[0030] The foundation-building device of the present invention has the following technical advantages. First, the thickness of the concrete before being leveled is controlled by the scraper plate 7 as a whole, so that the concrete can be evenly distributed, thereby improving the uniformity of the texture after the backrest is formed; second, the present invention can make the first flat top plate 8 and the second flat top plate 9 have a certain impact speed by slapping the first flat top plate 8 and the second flat top plate 9 downward, so that the slapping impact can be transmitted to the concrete during the process of pressing the concrete down, which is easy to disperse the air bags in the concrete and improve the forming quality of the backrest; third, the concrete is automatically slapped and leveled by the flat top assembly, which reduces the labor intensity of the personnel, and the slapping of the first flat top plate 8 and the second flat top plate 9 is more regular, which can avoid the problem of retained air bags caused by local uneven slapping.

[0031] In the illustrated embodiment, the scraper plate is connected to the housing of the reducer via a connecting rod.

[0032] In the illustrated embodiment, the difference in the setting of the lower limit of movement of the first flat top plate and the second flat top plate can be achieved by the difference in the length of the connecting rod on the upper side of the first flat top plate and the length of the second connecting rod of the second flat top plate, and can also be achieved by adjusting the differentiated setting of the outermost edge size of the cam in the first cam mechanism and the human cam mechanism.

[0033] In the illustrated embodiment, a further optimized configuration of the present invention is that, as shown in the figure, the first flat top plate 8 includes at least two split plate portions 801 spaced apart along the width direction of the curbstone.

[0034] As shown in the figure, by setting up two divided plate parts 801, the gap between the two divided plate parts 801 can be used to provide a channel for gas to escape when the first flat top plate 8 is slapped, thereby further reducing the gas content on the top of the backrest, and further reducing the resistance of the first flat top plate 8 when it is slapped downward, which is conducive to the first flat top plate 8 to slap downward quickly.

[0035] In a preferred embodiment, the present invention is further optimized in that, as shown in the figure, the top surface of the first flat top plate 8 is inclined downward from its center outward; the top surface of the second flat top plate 9 is inclined downward from its center outward. As shown in the figure, the concrete on the upper side can be easily dropped when the first flat top plate 8 and the second flat top plate 9 move up and down.

[0036] In the illustrated embodiment, with regard to the arrangement of the driving portion, to be more specific, as shown in the figure, the driving portion includes a driving motor 10 slidably arranged on the upper rail, and a reducer 11 connected to the driving motor 10, wherein the reducer 11 is provided with a first output shaft and a second output shaft, wherein the first output shaft is transmission-connected to the first flat top plate 8, and the second output shaft is transmission-connected to the second flat top plate 9.

[0037] In this way, the first flat top plate 8 and the second flat top plate 9 can be driven to move up and down respectively by one motor, which can simplify the number of power units of the driving part.

[0038] The reducer 11 may be an existing dual-output shaft reducer.

[0039] In an optional embodiment, two separate electric telescopic rods may be used to respectively drive the first flat top plate 8 and the second flat top plate 9 to move up and down.

[0040] In the illustrated embodiment, with regard to the structure of the driving portion, to be more specific, the reducer 11 is connected to a first cam mechanism 12 at the first output shaft position, and the reducer 11 is connected to a second cam mechanism 13 at the second output shaft position; the first cam mechanism 12 is connected to the first flat top plate 8, and the second cam mechanism 13 is connected to the second flat top plate 9, wherein the first cam mechanism 12 and the second cam mechanism 13 are arranged so that the first flat top plate 8 and the second flat top plate 9 are alternately moved to the lowest limit position.

[0041] As shown in the figure, the angular range area of ​​the first cam mechanism 12 and the angular range area of ​​the second cam mechanism 13 are staggered during the rotation process, so that when the first cam mechanism 12 rotates to the point where the first flat top plate 8 is approximately at the lowest limit position, the second flat top plate 9 is approximately at the highest position, and when the second cam mechanism 13 rotates to the point where the second flat top plate 9 is approximately at the lowest limit position, the first flat top plate 8 is approximately at the highest position. In this way, the first flat top plate 8 and the second flat top plate 9 can be used to alternately hit the concrete downward to reduce the reaction force on the flat top assembly during the concrete hitting process.

[0042] In the illustrated embodiment, the present invention is further optimized in that, as shown in the figure, the upper rail 5 is installed with a rack 14, and the reducer 11 is also connected to a walking wheel 15, half of the surface side of the walking wheel 15 forms a gear tooth 1501 meshing with the rack 14, and the other half forms a separation portion 1502 separated from the rack 14 during rotation; the first output shaft 1101 and the second output shaft 1102 and the walking wheel 15 have the same rotational angular velocity; the first cam mechanism 12 and the second cam mechanism 13 are arranged so that when the separation portion 1502 rotates to the position of the rack 14, the first flat top plate 8 and the second flat top plate 9 move up and down, and when the gear tooth 1501 rotates to the position of the rack 14, the first flat top plate 8 and the second flat top plate 9 are stationary and / or move upward.

[0043] As shown in the figure, by setting the running wheel 15, the driving motor can drive the first flat top plate 8 and the second flat top plate 9 to beat up and down, and the flat top assembly can be automatically moved and walked. Moreover, in the illustrated embodiment of the present invention, by optimizing the structure of the running wheel 15, the flat top assembly moves when stepping, and when the flat top assembly is stationary and does not move laterally, the first flat top plate 8 and the second flat top plate 9 move downward in turn, which can reduce the impact of the first flat top plate 8 and the second flat top plate 9 beating on the flat top assembly. The impact on the walking of the flat top assembly can be reduced to increase the service life of the rack 14 and the gear 1501, and can also reduce the drag marks on the top surface of the concrete and the lateral pushing of the concrete caused by the beating process of the first flat top plate 8 and the second flat top plate 9 due to the walking of the flat top assembly.

[0044] In the illustrated embodiment, for the structure of the present invention, to be more specific, as shown in the figure, when the rotation axis of the first cam mechanism 12, the rotation axis of the second cam mechanism 13 and the rotation axis of the walking wheel 15 are colinear, the downward stroke angle of the first cam mechanism 12 and the downward stroke angle of the second cam mechanism 13 partially overlap, and the gear tooth 1501 is located in the part outside the downward stroke angle of the first cam mechanism 12 and the downward stroke angle of the second cam mechanism 13.

[0045] like Figure 5As shown, within one rotation cycle of the first output shaft 1101, the second output shaft 1102 and the traveling wheel 15, the movement of the first cam mechanism 12 is triggered first, so that the first cam mechanism 12 drives the first flat top plate to slap downward first. During this process, the second flat top plate 9 is not triggered to slap downward, and the separation portion 1502 of the traveling wheel 15 corresponds to the position of the rack 14. After the downward movement of the first flat top plate 8 is completed, the downward movement of the second flat top plate 9 driven by the second cam mechanism 13 is started. After the downward movement of the second flat top plate 9 is completed, the gear tooth 1501 of the traveling wheel 15 rotates to the position of the rack 14, and the entire flat top assembly moves forward. After waiting for the gear tooth 1501 to separate from the rack 14, the movement of the first cam mechanism 12 is started.

[0046] In the illustrated embodiment, for the structure of the present invention, more specifically, as shown in the figure, the travel wheel 15 is connected to the first output shaft or the second output shaft.

[0047] like Figure 3 As shown, to be more specific, both ends of the first output shaft extend out of the reducer, and the travel wheel 15 is connected to the side of the first output shaft away from the first cam mechanism, so as to ensure that the rotation angular velocity of the travel wheel 15 and the first cam and the second cam 18 are consistent.

[0048] In the illustrated embodiment, with respect to the structure of the first cam mechanism 12 and the second cam mechanism 13, to be more specific, the structures of the first cam mechanism 12 and the second cam mechanism 13 are consistent. Here, the structure of the second cam 18 is taken as an example for explanation. The first cam mechanism 12 includes a second cam 18 installed on the first output shaft 1101, a housing 19 covering the outside of the second cam 18, and a second connecting rod 20 slidably extending into the inner side of the housing 19. The second connecting rod 20 is connected to the second flat top plate 9. The part of the second connecting rod 20 extending into the interior of the housing 19 is provided with a load-bearing end 21 extending into the lower side of the second cam 18. A return spring 22 is also provided between the second connecting rod 20 and the housing 19. The return spring 22 provides an upward force to the second connecting rod 20.

[0049] The structural forms of the first cam mechanism 12 and the second cam mechanism 13 are not limited to those shown in the figure. In an optional embodiment, other forms of cam mechanisms can also be used to drive the flat top plate to move up and down through a connecting rod.

[0050] In the illustrated embodiment, for the installation of the flat top assembly, more specifically, as shown in the figure, the drive motor 10 and the reducer 11 are integrally connected through the base, the upper rail 5 is arranged in an I-shape, the base has a slider that slides with the upper rail, the base is also provided with a slider that is slidably connected to the outer bracket 1, and the base can also be provided with a battery installation position, so that it can be equipped with its own battery, or it can also be powered by an external wire.

[0051] In the illustrated embodiment, the present invention is further optimized in that, Figure 2 and 3 As shown, there are respectively set up avoidance gaps between the edge of the first flat top plate 8 and the curbstone, and between the edge of the first flat top plate 8 and the template 4; a rubber sheet 16 is installed on the edge of the second flat top plate 9 facing the curbstone. As shown in the figure, by setting up the avoidance gap at the edge of the first flat top plate 8, the impact resistance of the first flat top plate 8 can be further reduced, and the avoidance gap can also be used to escape the air in the upper part of the backrest to ensure the molding quality of the backrest. Among them, the avoidance gap is preferably greater than or equal to 1 cm and less than or equal to 3 cm.

[0052] The edge of the second flat top plate 9 is provided with a rubber plate 16 to ensure that the second flat top plate 9 can partially contact the curbstone when tapped, so as to reduce residual concrete adhering to the side of the curbstone and improve the effect of the second flat top plate 9 on leveling the top surface.

[0053] In the illustrated embodiment, the structure of the present invention is further optimized in that a side scraper 17 is provided between the first flat top plate 8 and the second flat top plate 9, and the side scraper 17 can abut against the side surface of the curbstone.

[0054] As shown in the figure, by providing the side scraper 17, the concrete residue on the side of the curbstone can be further reduced to ensure the flat top effect of the backrest top surface.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
