Description

Technical Field

[0001] This utility model relates to the field of mechanical technology for road repair, specifically to a curbstone slipforming device. Background Technology

[0002] When slipforming damaged curb stones, the following paving process is used: 1. Template installation: Lifting equipment is used to assist in the erection of slipform molds and positioning devices. The straightness of the line is ≤5mm / 20m. The lifting platform is adjusted to control the slipform thickness of the repair material, which is 1-3cm. 2. Material preparation: Water is supplied by a water sampling vehicle, and a crane is used to lift the premixed repair material ton bags to the feeding silo. 3. Repair material mixing: The microcomputer measures the feed mass and controls the amount of water added according to the preset ratio. After the materials are mixed, they enter the discharge hopper. 4. Vibration and paving: The push plate pushes the material to the discharge hopper, the discharge temperature is controlled at 10-32℃, and the vibration frequency is adjusted to 8000-10000 times / min; 5. The height of the repair mold is controlled by the lifting platform, the repair material is vibrated into the repair mold, the positioner controls the linearity, the integrated machine moves forward at a uniform speed, and the repair mold is vibrated and extruded to form the shape.

[0003] During the construction process, the applicant discovered that because the repair material was first placed on the damaged curbstone, some of its moisture was absorbed by the curbstone before the repair mold arrived. As the repair mold slid forward to repair, the inner side of the front half of the repair mold, which mainly squeezed the repair material, was easily covered with slurry, resulting in an uneven repair surface when the back half was finished. Summary of the Invention

[0004] To address the technical problems existing in the background art, this utility model provides a curbstone slipforming device.

[0005] The technical solution of this utility model is as follows: A curbstone slipforming device includes a hopper, a rear transition chamber and a rear repair mold are arranged sequentially at the rear of the hopper, the shape of the rear repair mold matches the shape of the outer surface of the curbstone, the bottom of the rear transition chamber is empty, and it is connected to the rear repair mold through a rear chamber plate at the rear. A sealing plate is erected on the rear part of the upper surface of the post-repair mold. Several vertical plates are connected between the sealing plate and the rear compartment plate. Two adjacent vertical plates, the rear compartment plate, and the sealing plate form a water storage cavity. A water inlet hole is opened at the corresponding position of the water storage cavity at the highest position of the rear compartment plate.

[0006] During slipform repair work, water is added to the water storage cavity, allowing it to enter the repair material accumulated at the front of the rear compartment plate through the water inlet. The repair material at this location then enters below the rear repair mold and is squeezed onto the damaged curb. Because water was added in advance, the probability of dry grinding and adhesion between the repair material and the rear repair mold is reduced during the compression process, thus lowering the possibility of slurry sticking. It is no longer necessary to frequently raise the forming device for removal, thereby improving work efficiency. On-site verification showed that the effect was good.

[0007] As one implementation method, the post-repair mold is a continuous bending structure, including vertical plates, horizontal plates and inclined plates connected in sequence, which is consistent with the typical structure of the curbstone and is 1-3cm larger than the outer surface size of the curbstone.

[0008] Furthermore, the bottom of the vertical plate is connected to a horizontally extending side support plate, which extends forward to the foremost end of the curb slipforming device.

[0009] The design of the side support plate increases the strength of the repair mold and prevents the bottom edge of the vertical plate from warping. It also facilitates the placement of the transition chamber, allowing the repair material in the transition chamber to completely cover the exposed surface of the curbstone, which is convenient for subsequent extrusion molding by the repair mold.

[0010] In one implementation, the rear transition chamber is enclosed by a rear chamber plate, a second left chamber plate, a second right chamber plate, and a top plate. The lower edge of the second left chamber plate is flush with the edge of the inclined plate of the rear repair mold, and the second right chamber plate stands on the side support plate, leaving a gap with the vertical plate. The front of the rear transition chamber is positioned behind the unloading hopper, and the bottom is open. The enclosed space of the transition chamber is larger than the exposed part of the curbstone, allowing the repair material to fully cover the damaged curbstone.

[0011] In one implementation, the height of the sealing plate is lower than that of the rear compartment plate. The horizontal plate is the top of the repair mold, and vertical plates are set at the bends on both sides to form a water storage cavity at the top. The rear compartment plate has a first water inlet in the lower part of the corresponding area above the horizontal plate.

[0012] Preferably, the first water inlet is arranged parallel to the horizontal plate, and the opening width should not be too large. The purpose of adding water to the repair material is to prevent it from sticking to the inner side of the repair mold. Therefore, only a small amount of water needs to be added to prevent affecting the adhesion.

[0013] The water storage chamber has an opening at the top, allowing for manual water replenishment. Under the influence of gravity, the water in the storage chamber flows through the inlet into the transition chamber, and then seeps downwards into the repair material that will soon enter the post-repair mold.

[0014] This is a key inventive feature of this invention. It employs a method where water is pre-seeped into the repair material from the side to ensure the water and material are properly integrated, preventing adhesion when the material is squeezed into the repair mold. Instead of placing the water inlet at the bottom of the water storage chamber, this invention prioritizes pre-diluting the repair material to prevent adhesion, rather than adding water after the material has already adhered to the inner surface of the repair mold.

[0015] As a further preferred option, a vertical plate is provided above the edge of the inclined plate, and a second water inlet is provided in the lower part of the corresponding area above the inclined plate in the rear compartment plate. A second water storage cavity is formed above the inclined plate, which can replenish water to the repair material in the curb slope area.

[0016] The second inlet can be set parallel to the inclined plate.

[0017] To prevent repair materials in the rear transition chamber from being squeezed into the water storage chamber, a filter screen can be installed at the water inlet as a further improvement. Of course, even without a filter screen, since the water storage chamber and water inlet are completely exposed, manual cleaning will not affect the normal operation of the device.

[0018] As a further improvement, a front transition chamber and a front repair mold are also provided at the front of the hopper. The front transition chamber is similar in structure to the rear transition chamber, and it is enclosed by a front chamber plate, a first left chamber plate, a second right chamber plate and a top plate. The front repair mold and the rear repair mold have the same cross-sectional shape.

[0019] The front repair mold serves as a guide, pushing debris off the repair path. The front transition chamber connects to the discharge hopper to hold repair materials and also supports the connection frame for connecting to construction vehicles.

[0020] As a preferred embodiment, the first left compartment plate extends forward to the top of the front repair mold to increase the strength of the inclined plate section and prevent warping. The bottom of the hopper is empty, and the bottom positions of the front and rear material plates are higher than the top surface of the repair mold.

[0021] Through the above design, this utility model provides a curbstone slipform forming device. By using water to seep into the repair material in advance from the water inlet on the side of the rear compartment plate, the water and repair material are ensured to be fused together. Because water is added in advance, the probability of dry grinding and adhesion between the repair material and the rear repair mold is reduced during the extrusion process, and the possibility of slurry sticking is reduced. It is no longer necessary to frequently raise the forming device for removal, thereby improving work efficiency. After on-site verification, the effect is good. Attached Figure Description

Detailed Implementation

[0023] See Figures 1-4 This embodiment provides a curbstone slipforming device, including a hopper 1. A rear transition chamber 3 and a rear repair mold 5 are sequentially arranged at the rear of the hopper 1. A front transition chamber 2 and a front repair mold 4 are sequentially connected at the front of the hopper 1. The shapes of the front repair mold 4 and the rear repair mold 5 match the shape of the outer surface of the curbstone. The bottom of the rear transition chamber 3 is empty and is connected to the rear repair mold 5 through a rear chamber plate 31. The front transition chamber 2 has a similar structure to the rear transition chamber 3 and is connected to the front repair mold 4 through a front chamber plate 21.

[0024] In this embodiment, the front repair mold 4 and the rear repair mold 5 have the same cross-sectional shape, both being continuous bending structures, including a vertical plate 41, a horizontal plate 42, and an inclined plate 43 connected in sequence. The horizontal plate 42 is located at the top. See [reference needed]. Figure 5 As shown, the overall structure of the repair mold is consistent with that of a typical curbstone, but it is 1-3 cm larger than the outer surface of the curbstone.

[0025] See Figure 2 The bottom of the vertical plate 41 is connected to a horizontally extending side support plate 6, which extends forward to the front end of the front repair mold 4. The front and rear transition chambers and both sides of the discharge hopper 1 are welded to the side support plate 6.

[0026] The design of the side support plate 6 increases the strength of the repair mold and prevents the bottom edge of the vertical plate 41 from warping. On the other hand, it facilitates the placement of the transition chamber, so that the repair material in the transition chamber can completely cover the exposed surface of the curbstone, which is convenient for subsequent extrusion molding of the repair mold.

[0027] See Figure 1 A sealing plate 54 is erected on the rear part of the upper surface of the repair mold 5. The sealing plate 54 is arranged perpendicular to the length direction of the repair mold 5. Several vertical plates are connected between the sealing plate 54 and the rear compartment plate 31. Two adjacent vertical plates, the rear compartment plate 31, and the sealing plate 54 form a water storage cavity. The rear compartment plate 31 has a water inlet hole at the corresponding position of the water storage cavity at the highest position.

[0028] During slipform repair, water is added to the water storage cavity, allowing it to enter the repair material accumulated at the front of the rear compartment plate 31 through the water inlet. The repair material at this location then enters below the rear repair mold 5 and is squeezed onto the damaged curb. Because water was added in advance, the probability of dry grinding and adhesion between the repair material and the rear repair mold 5 is reduced during the compression process, thus lowering the possibility of slurry sticking. It is no longer necessary to frequently raise the forming device for removal, thereby improving work efficiency. The results were good after on-site verification.

[0029] The following is combined Figure 3 In one embodiment, the rear transition chamber 3 is formed by a rear chamber plate 31, a second left chamber plate 32, a second right chamber plate 33, and a top plate. The lower edge of the second left chamber plate 32 is flush with the edge of the inclined plate 43 of the rear repair mold 5. The second right chamber plate 33 stands on the side support plate 6, leaving a gap with the vertical plate 41. The front of the rear transition chamber 3 is positioned behind the unloading hopper 1, and the bottom is empty. The enclosed space of the transition chamber is larger than the exposed part of the curbstone, allowing the repair material to fully cover the damaged curbstone.

[0030] In one embodiment, the height of the sealing plate 54 is lower than that of the rear compartment plate 31. The horizontal plate 42 is the top of the repair mold. The first vertical plate 51 and the second vertical plate 52 are respectively provided at the bends on both sides. The two vertical plates are the same height, thus forming a water storage cavity at the top. The rear compartment plate 31 is provided with a first water inlet 311 in the lower part of the corresponding area above the horizontal plate 42.

[0031] The following is combined Figure 5 The first water inlet 311 is arranged parallel to the horizontal plate 42. The opening width should not be too large. The purpose of adding water to the repair material is to prevent it from sticking to the inner side of the repair mold. Therefore, only a small amount of water should be added to prevent affecting the adhesion.

[0032] The upper part of the water storage chamber is open, and water can be replenished manually. Under the action of gravity, the water in the water storage chamber enters the rear transition chamber through the first water inlet, and then seeps downward into the repair material that will soon enter the rear repair mold 5.

[0033] This is a key inventive feature of this invention. It employs a method where water is pre-seeped into the repair material from the side to ensure the water and material are properly integrated, preventing adhesion when the material is squeezed into the repair mold. Instead of placing the water inlet at the bottom of the water storage chamber, this invention prioritizes pre-diluting the repair material to prevent adhesion, rather than adding water after the material has already adhered to the inner surface of the repair mold.

[0034] As a further preferred embodiment, a third vertical plate 53 is provided above the edge of the inclined plate 43, and a second water inlet 312 is provided in the lower part of the corresponding area above the inclined plate 43 on the rear compartment plate 31. A second water storage cavity is formed above the inclined plate 43, which can replenish water to the repair material in the curb slope area.

[0035] The second inlet 312 can be set parallel to the inclined plate 43.

[0036] To prevent the repair material in the rear transition chamber 3 from being squeezed into the water storage chamber, a filter screen can be installed at the water inlet as a further improvement. Of course, even without a filter screen, since the water storage chamber and water inlet are completely exposed, manual cleaning will not affect the normal operation of the device.

[0037] See below. Figure 2 Let's introduce the structure of the front transition chamber 2 and the front repair mold 4. The front transition chamber 2 is similar in structure to the rear transition chamber 3, except that it is shorter. It is formed by the front chamber plate 21, the first left chamber plate 22, the second right chamber plate 33 and the top plate. The front repair mold 4 has the same cross-sectional shape as the rear repair mold 5, but is shorter.

[0038] The front repair mold 4 serves as a guide, pushing debris off the repair path. The front transition chamber 2 connects to the discharge hopper 1 to hold repair materials and also supports the connection between the connecting frame and the construction vehicle. Additionally, the top plate of the rear transition chamber 2 also supports the connection between the connecting frame and the construction vehicle.

[0039] As a preferred embodiment, the first left compartment plate 22 extends forward to the top of the front repair mold 4 to increase the strength of the inclined plate 43 and prevent warping.

[0040] In this embodiment, the feeding hopper 1 is a common funnel shape with an empty bottom and an upper opening larger than the lower opening. It is surrounded by a front material plate 11, a rear material plate 12, a left material plate 13, and a right material plate 14. The bottom positions of the front material plate 11 and the rear material plate 12 are higher than the top surface of the repair mold. The bottoms of the left material plate 13 and the right material plate 14 are welded to the side support plate 6 and are connected to the left and right chamber plates of the front transition chamber 2 and the rear transition chamber 3. There are no gaps at the joints to prevent material leakage.
