Description

Technical Field

[0001] The present invention relates to the technical field of road caulking, and particularly to a caulking device for road engineering construction. Background Art

[0002] During the repair of concrete road cracks, a road caulking machine is usually used. Through the caulking machine, the arched or shrinkage-cracked road surface in the cement concrete road surface can be filled, avoiding the generation of larger cracks or affecting vehicle driving, ensuring the flatness of the road or the safety of vehicle driving. The road caulking glue is processed by special processes from materials such as matrix heavy traffic asphalt, modifiers, stabilizers, and additives, and is a hot-melt polymer sealant with strong adhesion and high elasticity.

[0003] However, since the cracks in the road are usually wavy or irregular openings, during the use of the existing road caulking machines, the caulking glue is usually transported by a trolley. When encountering a crack, the caulking glue is released at the corresponding crack. Due to the irregular trajectory of the crack, when releasing the caulking glue, it is necessary to repeatedly adjust the position of the caulking machine by adjusting the trolley so that the falling position of the caulking glue corresponds to the opening of the crack. However, the trolley and the caulking machine are large in size and heavy in weight, and the adjustment process is very inconvenient. For smaller cracks, even if adjusted, it is impossible to ensure that the falling position of the caulking glue can exactly enter the crack, resulting in waste of the caulking glue.

[0004] In addition, there is also a handle-type caulking machine on the market currently. During operation, the caulking glue is transported from the caulking machine body through a hose to the handle. One operator holds the long hose, and another operator moves the handle along the corresponding crack to pour the caulking glue transported to the handle into the crack. The entire caulking work requires at least two operators, and it is troublesome to clean the pipeline after each use. There is a risk of scalding the handle operator by the high-temperature caulking glue.

[0005] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide a caulking device for road engineering construction, so as to solve the problems in the above background art that when the existing caulking machine releases the caulking glue at the irregular crack opening, due to its large size and heaviness, the adjustment is very inconvenient and the released caulking glue cannot accurately fall into the crack, and it is easy to be scalded by the high-temperature caulking glue during caulking operation.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0021] A driving mechanism, provided between the filling component and the pressing component, for driving the filling component and the pressing component to move synchronously.

[0022] Furthermore, first guide rails and second guide rails are respectively provided on both sides of the moving direction of the transfer hopper inside the first guide rail, so that when the feeding port of the transfer hopper deviates from the discharge port of the glue control component, the first guide rail and the second guide rail can guide the caulking glue falling from the glue control component into the transfer hopper.

[0023] Furthermore, the driving mechanism includes:

[0024] A driving plate, fixedly sleeved outside the blanking pipe, for driving the adapter hopper to move along the first guide rail;

[0025] A rack bar, connected to the upper end of the driving plate, with a gear member meshed at its upper end, and a first helical gear bar connected to one side of the gear member;

[0029] Furthermore, a first guide plate is connected to one side of the rack bar where it is located on the first guide rail;

[0030] The first guide plate extends into the first guide groove arranged on the side of the first guide rail, for guiding the movement of the rack bar.

[0036] An extension plate, connected to the lower end of the guide block, with a centering plate inclinedly arranged at its lower end, and there are two groups of the centering plates with the opening spacing gradually decreasing, for gathering the filling glue scattered at the crack to the middle crack;

[0037] A caulking material pressing plate, inclinedly connected to the upper end of the extension plate, for pressing the caulking glue that has not entered the crack into the crack.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] By opening the glue control assembly of the present invention, the sealant in the accommodating tank gradually drops onto the filler assembly through the glue control assembly. Continuously adjusting the position of the filler assembly enables the filler assembly to swing according to the track of the road crack, ensuring that the material dropping port of the filler assembly is always directly above the crack during the forward movement of the accommodating tank, and transferring the sealant dripping from the glue control assembly into the crack. Thus, when filling the irregular opening of the road crack, only a lightweight and small-sized adjusting filler assembly is required, without repeatedly adjusting the position of the sealant filling machine, which is convenient to use.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0049] Embodiment 1

[0050] Please refer to Figure 1-7 , the present invention provides a technical solution:

[0051] A caulking device for road engineering construction, including a storage tank 11, rollers 14 provided at the bottom of the storage tank 11, and a push rod 13 provided on one side of the storage tank 11, further including:

[0052] Transfer unit 1, including a glue control component 12 provided on one side of the storage tank 11 for controlling the discharge of the caulking glue in the storage tank 11;

[0053] Caulking unit 2, including a filling component 21 provided on one side of the storage tank 11 and below the discharge port of the glue control component 12 for adjusting the falling position of the caulking glue, and a pressing component 22 provided on one side of the filling component 21 for synchronously pressing the caulking glue falling into the crack opening.

[0054] It should be noted that when caulking an irregular crack, open the glue control component 12, so that the caulking glue in the storage tank 11 gradually drops onto the filling component 21 through the glue control component 12. Continuously adjust the position of the filling component 21 so that the filling component 21 swings according to the track of the road crack, ensuring that the material dropping port of the filling component 21 is always directly above the crack during the forward movement of the storage tank 11, and transferring the caulking agent dripping from the glue control component 12 into the crack. Thus, when caulking an irregular road crack opening, only the light and small filling component 21 needs to be adjusted, and there is no need to repeatedly adjust the position of the caulking machine, which is convenient to use.

[0055] As an improvement, as Figure 2-3 shown, the glue control component 12 includes:

[0056] Glue outlet pipe 121, connected to one side of the storage tank 11, for transferring the caulking glue in the storage tank 11 to the filling component 21;

[0057] Steering valve 122, rotatably provided inside the glue outlet pipe 121, for controlling the closed state of the glue outlet pipe 121;

[0058] Link rod 123, connected to the upper end of the steering valve 122;

[0059] The swing rod 124 is connected to one end of the connecting rod 123 opposite to the steering valve 122 and is used to cooperate with the connecting rod 123 to adjust the position of the steering valve 122.

[0060] The limit shaft 125 is connected to one side of the push rod 13 and is inserted into the swing rod 124 for limiting the swing rod 124.

[0061] As an improvement, as Figure 2-5 shown, the packing component 21 includes:

[0062] The first guide rail 211 is connected to one side of the receiving tank 11, and a guide groove 2111 is provided at the bottom thereof.

[0063] The transfer hopper 212 is slidably disposed in the first guide rail 211, and a blanking pipe 2123 penetrating through the guide groove 2111 is provided at the lower part thereof for transferring the sealant falling at the material control component.

[0064] The material guiding rail 213 is connected to the lower end of the blanking pipe 2123 for guiding the sealant falling from the blanking pipe 2123 into the crack; and

[0065] The driving mechanism 214 is disposed between the packing component 21 and the material pressing component 22 for driving the packing component 21 and the material pressing component 22 to move synchronously.

[0066] Furthermore, as Figure 5 、 Figure 7 shown, first guiding rails 2121 and second guiding rails 2122 are respectively provided on both sides of the moving direction of the transfer hopper 212 in the first guide rail 211 for guiding the sealant falling from the material control component 12 into the transfer hopper 212 when the feeding port of the transfer hopper 212 is offset from the discharging port of the material control component 12;

[0067] The first guiding rail 2121 and the second guiding rail 2122 are arranged obliquely.

[0068] Even further, the driving mechanism 214 includes:

[0069] The driving plate 2140 is fixedly sleeved on the outer side of the blanking pipe 2123 for driving the transfer hopper 212 to move along the first guide rail 211;

[0070] The rack bar 2141 is connected to the upper end of the driving plate 2140, and a gear member 2142 is engaged with the upper end thereof. A first helical gear bar 2144 is connected to one side of the gear member 2142;

[0071] The mounting bracket 2143 is connected to the upper end of the first guide rail 211 and is used to limit the gear member 2142.

[0072] The second helical gear rod 2145 meshes with one end of the first helical gear rod 2144 opposite to the gear member 2142, and a limit block 2147 for limiting the second helical gear rod 2145 is arranged on its outer side and is connected to the push rod 13.

[0073] The rotating rod 2146 is connected to the upper end of the second helical gear rod 2145 and is used to adjust the rotation of the second helical gear rod 2145.

[0074] Wherein, a first guide plate 21411 is connected to one side of the rack rod 2141 and the first guide rail 211.

[0075] The first guide plate 21411 extends into the first guide groove 2120 arranged on the side part of the first guide rail 211 and is used to guide the movement of the rack rod 2141.

[0076] It should be noted that in the specific implementation process of the present invention, the caulking glue is poured into the accommodating tank 11. Initially, the turning valve 122 closes the glue outlet pipe 121. The worker pushes the accommodating tank 11 through the push rod 13, and under the action of the rollers 14, it moves forward along the road surface. When encountering an irregular opening on the road surface, the swing rod 124 is pulled. The swing rod 124 rotates around the limit shaft 125 and drives the turning valve 122 to rotate through the connecting rod 123, so that the turning valve 122 switches the glue outlet pipe 121 from the closed state to the open state. At this time, the caulking glue in the accommodating tank 11 continuously flows into the adapter hopper 212 through the glue outlet pipe 121.

[0077] Subsequently, as Figure 4-7 shown, the rotating rod 2146 is rotated. The rotating rod 2146 drives the first helical gear rod 2144 to rotate through the second helical gear rod 2145. The first helical gear rod 2144 drives the rack rod 2141 to move along the first guide groove 2120 under the action of the first guide plate 21411 through the gear member 2142. The rack rod 2141 drives the blanking pipe 2123 to move along the guide groove 2111 through the driving plate 2140. The guide groove 2111 drives the guide rail 213 to move along the extending direction of the opening of the crack, so that the caulking glue falling into the adapter hopper 212 enters the crack through the blanking pipe 2123 and the guide rail 213 in sequence. Thus, only by adjusting the rotating rod 2146 can the blanking trajectory of the guide rail 213 be adjusted, ensuring that the blanking port of the guide rail 213 can always flexibly switch positions along the trajectory of the crack, and the adjustment is simple.

[0078] During the movement of the adapter hopper 212 along the inside of the first guide rail 211, by respectively arranging a first inlet rail 2121 and a second inlet rail 2122 on both sides of the adapter hopper 212, even when the opening of the adapter hopper 212 moves to be misaligned with the lower opening of the glue outlet pipe 121, the first inlet rail 2121 and the second inlet rail 2122 can still receive the sealant flowing out of the glue outlet pipe 121 and transfer it into the adapter hopper 212, ensuring that when the amplitude of the road crack faced by the adapter hopper 212 is relatively large, the guide rail 213 can still be continuously supplied with material through the feeding pipe 2123. At the same time, it also avoids waste caused by the sealant falling into the first guide rail 211 when the opening of the adapter hopper 212 moves to be misaligned with the lower opening of the glue outlet pipe 121.

[0079] Embodiment 2

[0080] As Figure 5-6 shown, among which the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The differences between this Embodiment 2 and Embodiment 1 are as follows:

[0081] As an improvement, as Figure 5-6 shown, the pressing component 22 includes:

[0082] A second guide rail 221, connected to one side of the storage tank 11 and arranged side by side with the first guide rail 211;

[0083] On one side of the second guide rail 221 where the rack bar 2141 is located, there is a second guide groove 2211. On the side of the rack bar 2141 opposite to the first guide plate 21411, there is a second guide plate 21412 extending into the inside of the second guide groove 2211, which is used to cooperate with the second guide groove 2211 to guide the rack bar 2141;

[0084] A guide block 222, slidably arranged inside the second guide rail 221, and its lower end penetrates through the second guide rail 221;

[0085] A pressing mechanism 223, arranged at the lower end of the guide block 222, for pressing the sealant after the filling component 21 discharges the material into the crack.

[0086] Furthermore, the pressing mechanism 223 includes:

[0087] An extension plate 2231, connected to the lower end of the guide block 222, and a centering plate 2232 is obliquely arranged at its lower end. There are two groups of the centering plates 2232 and the opening distance gradually decreases, which is used to gather the dispersed filling glue at the crack to the middle crack;

[0088] The side part of the extension plate 2231 is connected to the driving plate 2140;

[0089] The pressing plate 2233 is obliquely connected to the upper end of the extension plate 2231 and is used to press the caulking glue that has not entered the crack into the crack.

[0090] It should be noted that during the process of driving the material discharge pipe 2123 to move, the driving plate 2140 also synchronously drives the guide block 222 to move along the second guide rail 221. The guide block 222 drives the centering plate 2232 to move along both sides of the crack opening through the extension plate 2231, and aggregates the packing glue that slides out from the material guiding rail 213 and scatters near the crack opening into the crack, effectively avoiding waste caused by the caulking glue not flowing accurately into the crack when flowing out along the material guiding rail 213.

[0091] While the extension plate 2231 drives the centering plate 2232 to move, the extension plate 2231 also gradually levels and presses down the caulking glue gathered in the crack through the obliquely arranged pressing plate 2233, making the surface of the caulking glue filled in the crack smooth and having a good caulking effect.

[0092] In the present invention, the centering plate 2232 is arranged at the material discharge place close to the material guiding rail 213, and the centering plate 2232 and the material guiding rail 213 can move synchronously to ensure that when the caulking glue enters the crack, the centering plate 2232 can timely aggregate the caulking glue and level it through the pressing plate 2233.

[0093] In the present invention, the rotating rod 2146 and the swing rod 124 are both arranged at the push rod 13. When the worker pushes the accommodating tank 11 forward through the push rod 13, the swing rod 124 and the rotating rod 2146 can be timely controlled according to the track of the crack. The whole operation process does not need to use a long hose to transport the caulking glue, and the caulking operation can be carried out at a long distance during the caulking process, avoiding being scalded by the caulking glue during the caulking process and only one person can control the whole caulking work.

[0094] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0095] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
