Description

Technical Field

[0001] This utility model relates to the technical field of highway subgrade repair equipment, specifically a rapid subgrade repair device. Background Technology

[0002] The roadbed is the foundation of the railway or road surface, and is an earthwork structure formed through excavation or filling. The main function of the roadbed is to provide the necessary conditions for the laying of the railway or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the railway, locomotives, rolling stock, road surface, and traffic loads. Simultaneously, it transfers and diffuses the loads deep into the foundation. Over time, due to repeated consolidation and compression, highways experience excessive cumulative plastic deformation, resulting in ruts and puddles. Therefore, repair equipment is needed to maintain the roadbed.

[0003] For example, the national authorized patent announcement number CN214831581U discloses a highway subgrade repair device, including a base. The top of the base is equipped with a mixing box for processing repair materials. A control panel is located on one side of the mixing box. The bottom of the mixing box is connected to the top of the discharge pipe. The discharge pipe passes through the base and extends below it to connect with the spraying assembly. A support rod is located on the left side of the top of the base, and a moving assembly is located at the bottom of the base. The moving assembly, which facilitates the worker to push the device, includes support legs. The top of the support legs is connected to the four corners of the bottom of the base, and the bottom of the support legs is equipped with casters. A flattening assembly is located between two support legs on the same side of the bottom of the base. The pressure roller set in this utility model can effectively flatten the repair area without the need for workers to use other flattening equipment, reducing the labor intensity of workers and improving the working efficiency of the repair device.

[0004] However, in the process of filling the roadbed cracks with repair material, the repair material cannot fully fill every tiny gap in the cracks. This results in air bubbles and voids in the repair material not being squeezed out, which reduces the strength of the repaired area. This can lead to the repair material settling, cracking, or falling off during use, thus affecting the overall stability and durability of the roadbed. Utility Model Content

[0005] The purpose of this invention is to provide a rapid roadbed repair device to solve the problem mentioned in the background art where, during the process of filling roadbed cracks with repair material, the repair material cannot fully fill every tiny gap in the crack, resulting in air bubbles and voids in the repair material not being squeezed out, which leads to a reduction in the strength of the repaired area.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid roadbed repair device includes: a trolley frame, a handle fixedly installed at one end of the upper surface of the trolley frame, a U-shaped frame fixedly installed inside the trolley frame, a repair material cylinder rotatably installed on the upper surface of the U-shaped frame, the repair material cylinder located on the upper surface of the U-shaped frame being slidably sleeved inside a limiting ring, the limiting ring being fixedly installed on the upper surface of the U-shaped frame, and a discharge pipe fixedly installed on the lower surface of the U-shaped frame, the upper surface of the discharge pipe passing through the U-shaped frame and sealingly penetrating into the repair material cylinder, and a feed strip hole being opened on the outer surface of the discharge pipe located inside the repair material cylinder;

[0008] The trolley frame is fixedly equipped with a drive mechanism at one end, which can drive the repair cylinder to rotate in a sealed manner on the upper surface of the U-shaped frame and the outer surface of the discharge pipe.

[0009] The trolley frame is fixedly equipped with a vibration mechanism at one end. The vibration end of the vibration mechanism is flush with the discharge port of the discharge pipe and can be pushed out obliquely downward.

[0010] Preferably, a stirring rod is fixedly installed on the outer surface of the discharge pipe located inside the repair material cylinder, and the stirring rod can mix and stir the repair material inside the cylinder during rotation.

[0011] Preferably, a ball valve is installed between the discharge pipes located on the lower surface of the U-shaped frame.

[0012] Preferably, the driving mechanism includes a motor, which is fixedly installed at one end of the trolley frame. The output shaft of the motor passes through the U-shaped frame and is fixedly installed with a gear. The gear meshes with a gear ring, which is fixedly installed on the outer surface of the repair material cylinder and located on the lower surface of the limiting ring.

[0013] Preferably, the vibration mechanism includes an internal vibrator, which is fixedly installed at one end of the trolley frame. The vibration rod of the internal vibrator passes through a flexible hose to the lower surface of the trolley frame and is flush with the discharge port of the discharge pipe.

[0014] Preferably, a damping ring is fitted on the outer surface of the vibrating rod, the damping ring is fixedly installed at one end of the piston rod of the electric push rod, and the other end of the electric push rod is rotatably installed on the lower surface of the U-shaped frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the design of the repair material cylinder, discharge pipe, mixing rod, drive mechanism, and vibration mechanism, when repairing the roadbed, the lower discharge pipe can be aligned with the cracks on the roadbed by pushing the trolley frame. Then, the workers can open the ball valve to connect the discharge pipe with the repair material cylinder, allowing the repair material in the repair material cylinder to enter the discharge pipe through the feed strip hole on the outer surface of the discharge pipe. The repair material can then be discharged into the cracks through the discharge pipe and the ball valve for filling. After filling, the ball valve can be closed and the vibration mechanism can be started at the same time. The vibrating end of the vibration mechanism can be pushed into the cracks filled with repair material. The vibration of the vibration mechanism can effectively remove air bubbles in the repair material, making the filled repair material more compact, improving the overall density and strength of the repair material, and reducing the risk of subsidence, cracking, and other problems in the later stage.

[0017] Furthermore, during the process of pushing the trolley frame, the repair material cylinder can be rotated on the upper surface of the U-shaped frame by activating the drive mechanism. During the rotation of the repair material cylinder, the internal repair material can collide and mix with the stirring rod fixedly installed on the outer surface of the discharge pipe, which can make the repair material more uniform and avoid the layering or sedimentation that may occur during storage or transportation. This ensures the uniformity of the repair material, thereby making the material performance more stable during the filling process and ensuring the consistency of repair quality.

[0018] 2. Through the design of the motor, gears, gear ring, internal vibrator, vibrating rod, and electric push rod, after the repair material is discharged into the crack for filling, the electric push rod can be activated to push the damping ring on the outer surface of the piston rod. The damping ring then pushes the vibrating rod of the internal vibrator through a bent hose into the crack for vibration. The vibration of the internal vibrator can effectively remove air bubbles in the repair material, making the filled repair material more compact. During the pushing of the trolley frame, the motor can also be activated to drive the gear to rotate. The rotation of the gear drives the gear ring to drive the repair material cylinder to rotate. During the rotation of the repair material cylinder, the internal repair material can collide and mix with the stirring rod fixedly installed on the outer surface of the discharge pipe, making the repair material more uniform and avoiding the stratification or sedimentation that may occur during storage or transportation. This ensures the uniformity of the repair material. The combination of vibration and stirring functions can simultaneously address the uniformity and compactness of the repair material, which can reduce subsequent adjustments and replenishments during the repair work and shorten the construction time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This embodiment provides the following technical solution:

[0025] like Figure 1 As shown, a roadbed rapid repair device includes: a trolley frame 1, a handle 101 fixedly installed at one end of the upper surface of the trolley frame 1, wheels installed at the bottom of the trolley frame 1, a U-shaped frame 106 fixedly installed inside the trolley frame 1, a repair material cylinder 103 rotatably installed on the upper surface of the U-shaped frame 106, the repair material cylinder 103 located on the upper surface of the U-shaped frame 106 is simultaneously slidably sleeved inside by a limiting ring 102, the limiting ring 102 is fixedly installed on the upper surface of the U-shaped frame 106, a discharge pipe 104 is fixedly installed on the lower surface of the U-shaped frame 106, the upper surface of the discharge pipe 104 is sealed through the U-shaped frame 106 and enters the repair material cylinder 103, and a feed strip hole is opened on the outer surface of the discharge pipe 104 located inside the repair material cylinder 103;

[0026] Among them, a drive mechanism 2 is fixedly installed at one end of the trolley frame 1. The drive mechanism 2 can drive the repair cylinder 103 to rotate in a sealed manner on the upper surface of the U-shaped frame 106 and the outer surface of the discharge pipe 104.

[0027] Among them, a vibration mechanism 3 is fixedly installed at one end of the trolley frame 1. The vibration end of the vibration mechanism 3 is flush with the discharge port of the discharge pipe 104 and can be pushed out obliquely downward.

[0028] A stirring rod 107 is fixedly installed on the outer surface of the discharge pipe 104 located inside the repair material cylinder 103. The stirring rod 107 can mix and stir the repair material inside the cylinder 103 during rotation.

[0029] A ball valve 105 is installed between the discharge pipes 104 located on the lower surface of the U-shaped frame 106.

[0030] Through the design of the repair material cylinder 103, the discharge pipe 104, the mixing rod 107, the drive mechanism 2, and the vibration mechanism 3, when repairing the roadbed, the lower discharge pipe 104 can be driven by the push cart frame 1 to face the cracks on the roadbed. Then, the workers can open the ball valve 105 to connect the discharge pipe 104 with the repair material cylinder 103, allowing the repair material in the repair material cylinder 103 to enter the discharge pipe 104 through the feed strip hole on the outer surface of the discharge pipe 104. The repair material can then be discharged into the cracks through the discharge pipe 104 and the ball valve 105 for filling. After filling, the ball valve 105 can be closed and the vibration mechanism 3 can be started at the same time. The vibrating end of the vibration mechanism 3 can be pushed into the cracks filled with repair material. The vibration of the vibration mechanism 3 can effectively remove air bubbles in the repair material, making the filled repair material more compact, improving the overall density and strength of the repair material, and reducing the risk of subsidence, cracking, and other problems in the later stages.

[0031] Furthermore, during the process of pushing the trolley frame 1, the repair material cylinder 103 can be rotated on the upper surface of the U-shaped frame 106 by activating the drive mechanism 2. During the rotation of the repair material cylinder 103, the internal repair material can collide and mix with the stirring rod 107 fixedly installed on the outer surface of the discharge pipe 104, which can make the repair material more uniform and avoid the layering or sedimentation that may occur during the storage or transportation of the material. This ensures the uniformity of the repair material, thereby making the performance of the material more stable during the filling process and ensuring the consistency of the repair quality.

[0032] like Figures 2-3 As shown, the drive mechanism 2 includes a motor 201, which is fixedly installed at one end of the trolley frame 1. The output shaft of the motor 201 passes through the U-shaped frame 106 and is fixedly installed with a gear 202. The gear 202 meshes with a gear ring 203, which is fixedly installed on the outer surface of the repair material cylinder 103 and located on the lower surface of the limiting ring 102.

[0033] The vibration mechanism 3 includes an internal vibrator 301, which is fixedly installed at one end of the trolley frame 1. The vibration rod 304 of the internal vibrator 301 passes through a hose to the lower surface of the trolley frame 1 and is flush with the discharge port of the discharge pipe 104.

[0034] A damping ring 303 is fitted on the outer surface of the vibrating rod 304. The damping ring 303 is fixedly installed at one end of the piston rod of the electric push rod 302, and the other end of the electric push rod 302 is rotatably installed on the lower surface of the U-shaped frame 106.

[0035] Through the design of motor 201, gear 202, gear ring 203, internal vibrator 301, vibration rod 304, and electric push rod 302, after the repair material is discharged into the crack for filling, the electric push rod 302 can be activated to push the damping ring 303 on the outer surface of the piston rod. The damping ring 303 then pushes the vibration rod 304 of the internal vibrator 301, which is inserted into the crack through a bent hose for vibration. The vibration of the internal vibrator 301 can effectively remove air bubbles in the repair material, making the filled repair material more compact. Furthermore, during the process of pushing the trolley frame 1, the motor 201 can be activated to drive the gear 202 for further... The rotation of the gear 202 drives the gear ring 203 to rotate the repair material cylinder 103. During the rotation of the repair material cylinder 103, the internal repair material collides and mixes with the stirring rod 107 fixedly installed on the outer surface of the discharge pipe 104, which makes the repair material more uniform and avoids the stratification or sedimentation that may occur during storage or transportation. This ensures the uniformity of the repair material. The combination of vibration and stirring functions can simultaneously address the uniformity and density of the repair material, thereby reducing subsequent adjustments and replenishments during the repair work and shortening the construction time.

[0036] Based on the above technical solution, the working steps of this solution are summarized as follows: When repairing the roadbed, the lower discharge pipe 104 can be aligned with the cracks on the roadbed by pushing the trolley frame 1. Then, the worker can open the ball valve 105 to connect the discharge pipe 104 with the repair material cylinder 103, allowing the repair material in the repair material cylinder 103 to enter the discharge pipe 104 through the feed strip hole on the outer surface of the discharge pipe 104. The repair material can then be discharged into the cracks through the discharge pipe 104 and the ball valve 105 for filling. After filling is completed, the ball valve 105 can be closed and the electric push rod 302 can be activated simultaneously to push the vibration damping ring 303 on the outer surface of the piston rod. The vibration damping ring 303 will then push the inner... The vibrating rod 304 of the vibrator 301 is inserted into the crack through a bent hose to vibrate. The vibration of the inner vibrator 301 can effectively remove air bubbles in the repair material, making the filled repair material more compact. During the process of pushing the trolley frame 1, the motor 201 can be started to drive the gear 202 to rotate. The rotation of the gear 202 will drive the gear ring 203 to drive the repair material cylinder 103 to rotate. During the rotation of the repair material cylinder 103, the repair material inside can collide and mix with the stirring rod 107 fixedly installed on the outer surface of the discharge pipe 104, which can make the repair material more uniform and avoid the stratification or sedimentation that may occur during the storage or transportation of the material.

[0037] In summary, this device combines vibration and mixing functions, enabling it to simultaneously address the uniformity and density of repair materials. This improves the overall density and strength of the repair materials, reducing the risk of later problems such as subsidence and cracking. Consequently, it reduces the need for subsequent adjustments and additions during the repair process, thus shortening the construction time.
