Description

Technical Field

[0001] This utility model relates to the technical field of road surface maintenance equipment, and in particular to a rapid repair, sealing and filling device for road cracks. Background Technology

[0002] In modern road maintenance engineering, various types of cracks often appear on the road surface due to long-term vehicle rolling and the thermal expansion and contraction of the natural environment. If the cracks are not repaired and sealed in time, rainwater will seep into the roadbed, causing damage to the road structure and affecting driving safety. At present, the repair work for road cracks mainly relies on manual hand-held crack filling guns or simple pushcart-type crack filling equipment to fill the cracks with repair materials such as sealant or asphalt.

[0003] However, existing simple cart-type crack sealing equipment uses a relatively fixed discharge nozzle. Since road surface cracks often have irregular, meandering shapes and varying widths, the fixed nozzle cannot accurately align with the irregularly changing crack path as the cart moves in a straight line. This forces operators to frequently manually adjust the cart's direction or laboriously control the nozzle position to follow the crack's path. This operating method, lacking automated oscillating filling functionality, not only greatly increases the labor intensity and working time of construction workers, but also easily leads to incomplete filling of crack edges or uneven coverage of sealing material due to alignment deviations, ultimately seriously affecting the sealing effect and project quality of road crack repair.

[0004] Therefore, this utility model proposes a rapid repair and sealing filling device for road cracks to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, the nozzle position of the simple cart-type crack filling equipment is relatively fixed, which makes it difficult to accurately align with the irregular cracks. This requires the operator to frequently adjust the direction of travel, resulting in low repair efficiency, uneven sealing, and poor repair quality due to the lack of dust removal function. The present invention aims to provide a road crack rapid repair and sealing filling device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a road crack rapid repair and sealing filling device, including: a trolley, a push rod fixedly connected to the top of the trolley, a roller rotatably connected to the bottom of the trolley, a storage tank fixedly installed on the front side of the top of the trolley, and a filling mechanism installed on the bottom of the inner wall of the trolley.

[0007] The filling mechanism has a mechanical structure that can convert the rotational driving force output by the motor into the reciprocating linear motion of the nozzle.

[0008] Furthermore, the filling mechanism includes a fixed frame fixedly connected to the top surface inside the trolley, a rotating cylinder rotatably connected to the bottom of the fixed frame, a movable groove opened on the surface of the rotating cylinder, a movable ring slidably connected inside the movable groove, a sliding rod inserted through the top of the movable ring, both ends of the sliding rod fixedly connected to the inner wall of the fixed frame, a nozzle fixedly connected to the side of the movable ring, a motor fixedly connected to one end of the rotating cylinder, a conduit connected to the bottom of the storage tank, and the end of the conduit away from the storage tank connected to the nozzle. The filling mechanism, the storage tank, and the trolley are combined through the support of the fixed frame and the flexible connection of the conduit. The rotating cylinder is driven by the motor to rotate, and the limiting effect of the movable groove and the sliding rod drives the nozzle to move automatically back and forth to fill.

[0009] Preferably, the road crack rapid repair and sealing filling device also includes a cleaning mechanism, which includes a fixing rod and a nozzle. The fixing rod is fixedly connected to the rear side of the inner wall of the trolley near the roller, and the nozzle is fixedly connected to the middle of the fixing rod for close-range air blowing and dust removal of the road crack before the filling operation.

[0010] Preferably, the cleaning mechanism further includes a rotating frame and a rotating rod. The left and right ends of the fixed rod are rotatably connected to the rotating frame and the rotating rod, respectively. The rotating rod is fixedly connected to one side of the rotating frame and is used to adjust the nozzle angle flexibly to adapt to the cleaning needs of different road conditions.

[0011] Preferably, the cleaning mechanism also includes an air pump, which is fixedly installed on the top of the cart, and the air outlet of the air pump is connected to the nozzle to provide a continuous and stable high-pressure cleaning airflow to the nozzle.

[0012] Preferably, a fixing strap is wrapped around the outside of the air pump, and the two ends of the fixing strap are fixedly connected to the top of the trolley to increase the stability of the air pump during operation and prevent the air pump from shifting or falling off due to vibration.

[0013] Preferably, a valve is also connected between the air pump and the nozzle. The valve is located on the air pump outlet pipe and is used to adjust the airflow delivered by the air pump to the nozzle according to actual needs.

[0014] Preferably, the conduit is a flexible hose, and the moving groove is distributed in a spiral reciprocating pattern along the axis of the rotating drum. The hose material can adapt to the deformation requirements when the nozzle moves back and forth, and the spiral reciprocating moving groove can smoothly guide the moving ring to perform periodic left and right reciprocating motion.

[0015] Preferably, the motor is fixedly mounted on the side wall of the fixed frame, and the motor output shaft is coaxially and fixedly connected to the central axis of the rotating drum to ensure the directness and efficiency of power transmission and reduce mechanical transmission losses.

[0016] This utility model has the following beneficial effects: 1. This utility model uses a motor to drive a rotating drum to rotate. The rotating drum surface has a spiral reciprocating moving groove, which, together with a sliding rod, restricts the rotation of the moving ring, thereby driving the nozzle to move in a straight line from left to right. This solves the problems of low efficiency in manual crack repair and difficulty in achieving uniform and comprehensive coverage for irregular cracks in the prior art. It achieves the effect of automatic wide-scanning filling and significantly improves the efficiency and quality of road crack repair.

[0017] 2. This utility model solves the problem in the prior art where the repair material cannot adhere tightly to the road surface due to the accumulation of dust and debris inside the crack, thus affecting the sealing performance. It achieves the effect of ensuring effective adhesion between the repair material and the inner wall of the crack and improving the sealing stability and service life after road crack repair.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 6 This utility model provides a road crack rapid repair and sealing filling device, which aims to solve the structural defects of existing road crack repair equipment, which require manual alignment and filling of cracks, resulting in low operation efficiency, uneven filling, and difficulty in cleaning dust inside the cracks, thus affecting the sealing effect.

[0022] Please refer to Figure 1 and Figure 2 The road crack rapid repair and sealing filling device includes a trolley 1, a push rod 4 fixedly connected to the top of the trolley 1, and rollers 5 rotatably connected to the bottom of the trolley 1. The trolley 1 serves as the carrier for moving and installing the entire device. The push rod 4 is fixedly located at the rear top of the trolley 1 so that the operator can manually push and control the direction of the device. The rollers 5 are distributed at the four corners of the bottom of the trolley 1. The device can move flexibly on the road surface by rotating the rollers 5. A storage tank 6 is fixedly installed on the front top of the trolley 1. The storage tank 6 has a cavity inside for storing fluid repair materials such as asphalt or sealant. A filling mechanism 2 is installed at the bottom of the inner wall of the trolley 1. The filling mechanism 2 is located in the inner space of the trolley 1 and corresponds downward to the location of the road crack. The filling mechanism 2 is used to automatically and evenly spray the material in the storage tank 6 into the crack.

[0023] Please refer to Figure 1 , Figure 4 and Figure 5The filling mechanism 2 includes a fixed frame 201 fixedly connected to the top surface inside the trolley 1. The fixed frame 201 serves as the supporting base for the filling assembly. A rotating cylinder 206 is rotatably connected to the bottom of the fixed frame 201. The rotating cylinder 206 can rotate axially relative to the fixed frame 201. A movable groove 208 is formed on the surface of the rotating cylinder 206. The movable groove 208 is distributed in a spiral reciprocating pattern along the axial direction of the rotating cylinder 206. A movable ring 204 is slidably connected inside the movable groove 208. The movable ring 204 is sleeved on the outside of the rotating cylinder 206 and inserted into the movable groove 208. A sliding rod 202 is inserted through the top of the movable ring 204. The two ends of the sliding rod 202 are fixedly connected to the inner wall of the fixed frame 201. The sliding rod 202 restricts the movable ring 204 from rotating with the rotating cylinder 206, thereby forcing the movable ring 204 to rotate. 04. The slide bar 202 moves in a straight line and reciprocates. The moving ring 204 is fixedly connected to the side of the spray pipe 205. The spray pipe 205 moves synchronously with the moving ring 204 to achieve wide-area spraying. One end of the rotating drum 206 is fixedly connected to the motor 207. The motor 207 is fixedly installed on the side wall of the fixed frame 201. The output shaft of the motor 207 is coaxially fixedly connected to the central axis of the rotating drum 206 to provide rotational power. The bottom end of the storage tank 6 is connected to the conduit 203. The end of the conduit 203 away from the storage tank 6 is connected to the spray pipe 205. The conduit 203 is a flexible hose to adapt to the reciprocating movement of the spray pipe 205. The rotating drum 206 is driven by the motor 207 to rotate, which, in conjunction with the action of the moving groove 208 and the slide bar 202, realizes the automatic covering and filling of irregular cracks by the spray pipe 205.

[0024] Please refer to Figure 3 and Figure 6 The cleaning mechanism 3 includes an air pump 305, a fixing strap 306, a valve 307, a nozzle 304, and components for support and adjustment. The air pump 305 is fixedly installed on the top plane of the trolley 1. The fixing strap 306 is wrapped around the outside of the air pump 305. The two ends of the fixing strap 306 are fixedly connected to the top of the trolley 1. The fixing strap 306 securely locks the air pump 305 to increase the stability of the air pump 305 during operation. The air outlet of the air pump 305 is connected to the valve 307 through a pipeline. The valve 307 is set in the middle of the pipeline to realize the adjustment of the exhaust volume. The end of the valve 307 away from the air pump 305 is connected to the nozzle 304. The nozzle 304 is used to spray high-pressure airflow into the ground cracks for dust removal.

[0025] Meanwhile, in order to achieve position support and angle adjustment of the nozzle 304, the nozzle 304 is fixedly connected to the middle of the fixed rod 301. The fixed rod 301 is fixedly connected to the rear inner wall of the trolley 1 near the roller 5. The left and right ends of the fixed rod 301 are respectively rotatably connected to the rotating frame 302 and the rotating rod 303. The rotating rod 303 is fixedly connected to one side of the rotating frame 302. By cooperating with the rotating frame 302 and the rotating rod 303, the angle of the fixed rod 301 and the nozzle 304 can be adjusted to ensure that the nozzle 304 is accurately aligned with the crack area. The airflow generated by the air pump 305 is adjusted by the valve 307 and then sprayed out by the nozzle 304. The wind power is used to remove dust from the cracks on the road surface, ensuring the sealing and adhesion of the filling material when the filling mechanism 2 fills it.

[0026] As a preferred embodiment of the key internal structure of the filling mechanism 2, in order to ensure that the nozzle 205 can achieve stable and continuous left-right reciprocating filling action, the moving groove 208 opened on the surface of the rotating cylinder 206 has a spiral reciprocating distribution structure along the axial direction of the rotating cylinder 206. The moving ring 204 embedded in the moving groove 208 restricts the limiting action of the sliding rod 202 through the spiral reciprocating structure, converting the rotational motion of the rotating cylinder 206 into linear reciprocating motion. At the same time, the conduit 203 connecting the bottom of the storage tank 6 and the nozzle 205 is made of a flexible hose material. The hose material conduit 203 can adapt to the positional changes of the nozzle 205 when it moves back and forth with the moving ring 204 and undergo corresponding bending deformation to maintain smooth connection and not interfere with the movement of the nozzle 205.

[0027] As a preferred embodiment for the specific installation and connection of the power drive component, in order to ensure the stability and accuracy of power transmission, the motor 207 is fixedly installed on the side wall of the fixed frame 201 by bolts or bracket structure. The output shaft of the motor 207 is coaxially fixedly connected with the central axis of the end of the rotating drum 206. This coaxial fixed connection method ensures that the rotational torque output by the motor 207 during operation can be directly and smoothly transmitted to the rotating drum 206 and drive the rotating drum 206 to rotate at the bottom of the fixed frame 201.

[0028] As a preferred embodiment of the air path control part of the cleaning mechanism 3, in order to achieve flexible adjustment of the cleaning intensity of the cracks, a valve 307 for adjusting the exhaust volume is connected in series on the connecting pipe between the air outlet of the air pump 305 and the nozzle 304. The two ends of the valve 307 are respectively sealed and connected to the air outlet pipe of the air pump 305 and the air inlet pipe of the nozzle 304. By adjusting the opening of the valve 307, the cross-sectional area of ​​the pipe is changed, thereby controlling the flow rate of the high-pressure airflow delivered from the air pump 305 to the nozzle 304.

[0029] Working principle: When road crack repair is required, the operator holds the push rod 4 and pushes the cart 1 to the area to be repaired using the rollers 5. When the operation starts, the cleaning mechanism 3 is activated first, and the air pump 305 generates high-pressure airflow. The airflow is delivered to the nozzle 304 after the flow rate is controlled by the valve 307. The nozzle 304 blows air to remove dust from the crack to ensure the adhesion of the subsequent material. The spray angle of the nozzle 304 is adjusted by the rotating frame 302 and the rotating rod 303 to adapt to different road conditions. After cleaning, the filling operation is carried out. The repair material inside the storage tank 6 enters the nozzle 205 through the conduit 203. At the same time, the motor 207 is started to drive the rotating drum 206 to rotate. The spiral reciprocating moving groove 208 on the surface of the rotating drum 206 drives the moving ring 204 embedded in the moving groove 208 to move. Since the sliding rod 202 passes through the moving ring 204 and restricts the circumferential rotation of the moving ring 204, the moving ring 204 is forced to slide linearly back and forth along the axis of the sliding rod 202. This drives the nozzle 205, which is fixedly connected to the side of the moving ring 204, to sweep left and right back and forth in sync. The reciprocating motion of the nozzle 205, together with the linear forward movement of the trolley 1, realizes the wide, uniform and automated sealing and filling of irregular cracks in the road, thereby solving the problems of low efficiency and incomplete filling of manual repair.
