Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a structure and method for protecting the twisting of expansion joints of a rough mountain road. Background Art

[0002] The twist protection structure of expansion joints on rugged mountain roads plays a vital role in road maintenance. The general process of road maintenance begins with a road surface inspection. During regular inspections and special inspections, once it is found that the expansion joint twist protection structure has problems such as sealant failure, excessive gaps, or debris blocking, it is necessary to further determine whether excavation and glue patching operations are required. When it is found that the original sealant is cracked and peeled, resulting in a decrease in the waterproof and dustproof functions of the expansion joint, it is necessary to consider excavating and removing the damaged sealant. In the process of cleaning the debris in the expansion joint, if it is found that the debris is embedded deep in the gap and difficult to remove by conventional cleaning methods, it may be necessary to carefully perform excavation operations to completely remove the debris while avoiding additional damage to the expansion joint structure. After the excavation and debris removal are completed, the gap must be thoroughly cleaned and dried to ensure the bonding effect of the glue patch.

[0003] The Chinese patent with publication number CN110424234A discloses an expansion joint cutting device for road construction, which aims to solve the problem of not needing to move the mobile frame during the expansion joint cutting process. The rotating cutting blade is driven to move back and forth laterally by the provided translation mechanism, so as to quickly open the expansion joint. The expansion joint can be opened by a single reciprocating movement of the prism on the threaded rod. The opening process is easy to operate and has high work efficiency, and a high-quality cutting effect of the expansion joint is achieved when the mobile frame is in a stable state.

[0004] In the prior art, in the scenario of excavating and filling expansion joints on rugged mountain roads, the excavation, cleaning and liquid glue filling of expansion joints are mostly carried out separately. During the liquid glue filling process, the liquid glue itself is prone to solidification and stratification, resulting in uneven distribution. If there is a lack of effective control during filling, the liquid glue will be unevenly distributed, resulting in accumulation or insufficient filling, and good contact with the joint wall cannot be guaranteed, which seriously affects the bonding strength and the protection effect of the expansion joint. When cleaning the expansion joint, dust and debris are easy to fly around, which not only destroys the cleanliness of the construction environment, but also interferes with subsequent operations. Moreover, if the original impurities in the joint are not removed in advance, it will hinder the liquid glue from fitting closely to the joint wall, greatly reducing the filling quality, causing various filling problems and even rework, seriously hindering construction efficiency, making it difficult to smoothly advance the liquid glue filling work, and ultimately affecting the construction results and road quality of the entire expansion joint torsion protection structure.

[0005] Therefore, the present invention provides a twisting protection structure for expansion joints on rugged mountain roads, which can remove impurities, improve the construction environment for liquid glue filling of expansion joints, and at the same time improve the quality and efficiency of liquid glue filling of expansion joints.

The inner side is slidably connected to the limit rod 76, the cover plate 8 is fixed to the outside of the other end of the feed pipe 72, two springs 1 are fixed to the top of the cover plate 8, the bottom of the limit rod 76 is fixedly connected to the cover plate 8, the tops of the two springs 1 are fixedly connected to the bottom of the side plate 73, the movable rod 74 and the limit rod 76 are located on the inner side of the two springs 1, and a baffle 77 is fixed on the side of the movable plate 62 away from the feed pipe 72. The baffle 77 is located at the bottom of the cover plate 8, and air grooves are opened on both sides of the baffle 77. The air grooves are designed to be inclined toward the ground, which can guide the path of dust when the vacuum cleaner 71 is working.

[0025] In this embodiment, when the pulley moves to the top of the expansion joint, the pulley moves to the bottom of the expansion joint under the action of external force, and the baffle 77 follows the movable rod 74 to move into the inside of the expansion joint. The cover plate 8 fits against the ground, and the cover plate 8, the movable rod 74 and the liquid glue form a semi-sealed space in the expansion joint. At the same time, the vacuum cleaner 71 is started. After the expansion joint is cut, the large particles of cutting debris are guided to the ground by the baffle 77, and the small particles of cutting debris are discharged from the discharge pipe 75 through the feed pipe 72 and the inside of the vacuum cleaner 71 under the action of the vacuum cleaner 71, thereby completing the cleaning of the expansion joint.

[0026] Specifically, the injection piece 10 is assembled to cooperate with the nozzle 9 to inject glue into the expansion joint; the injection piece 10 includes a material tank 101, which is fixed to the top of the base plate 2, and the material tank 101 is located on the top of the vacuum cleaner 71. A hydraulic pump 102 is fixed on the top of the base plate 2, and the hydraulic pump 102 is located on the side of the material tank 101 away from the motor 5. The input end of the hydraulic pump 102 is fixedly connected to the material tank 101 through a pipeline, and the nozzle 9 is fixedly connected to the output end of the hydraulic pump 102 through a pipeline. A limiting plate 103 is fixed to one side of the base plate 2, and a round rod 104 is slidably connected to the inner side of the limiting plate 103. A fixed plate 106 is fixed to the side of the chassis 1 close to the nozzle 9, and the fixed plate 106 is located below the limiting plate 103. The fixed plate 106 is provided with a horizontal section and a vertical section, and the end of the cover plate 8 close to the fixed plate 106 is slidably engaged with the vertical section of the fixed plate 106.

[0027] In this embodiment, when the nozzle 9 and the driving rod 11 move to the top of the expansion joint, the sealing plate and the driving rod 11 move to the side close to the ground under the action of external force, so that the bottom of the touch plate 111 is in contact with the ground, and then the hydraulic pump 102 is started to extract the liquid glue in the tank 101 and pump it into the space formed by the sealing plate in the expansion joint and the baffles 77 at both ends of the expansion joint through the nozzle 9 to complete the glue injection; When the nozzle moves to align with the terminal end of the expansion joint, fix another fixed plate 106 to the terminal end of the expansion joint, and limit the liquid glue to the inside of the expansion joint by two baffles 77. Use the hand-belt limiting plate 103 and the two movable rods 74 to restore them to their original positions, and control the two hydraulic cylinders 64 to retract to their original positions. Under the action of two springs four, the locking rod 67 limits the round rod 104, the movable rod 74 and the limiting rod 76 again, and then wait for the liquid glue to cool down.

[0028] Specifically, the driving member 12 also includes a large gear 123, which is fixedly connected to the output end of the motor 2 121 through a connecting component. A transmission rod 124 is fixed to the top of the chassis 1 through a connecting component. A small gear 125 is fixed to one end of the transmission rod 124 close to the motor 2 121, and a bevel gear 126 is fixed to the other side of the transmission rod 124. The top of the fixed plate 106 is rotatably connected to the bevel gear 2 127. The driving rod 11 is rotatably connected to the bottom of the other round rod 104, and the driving rod 11 is slidably engaged with the bottom of the bevel gear 2 127. The bottom of the driving rod 11 is fixed to a touch plate 111.

[0029] In this embodiment, when this device moves, the output end of motor 2 121 drives the large gear 123 to rotate, and the large gear 123 drives the transmission rod 124 to rotate through the meshing action with the small gear 125. The transmission rod 124 drives the drive rod 11 to rotate through the meshing action of bevel gear 126 and bevel gear 2 127. The drive rod 11 drives the touch plate 111 to rotate, and the touch plate 111 smoothes the liquid glue during the movement.

[0030] During the forward movement, the cover plate 8, the fixed plate 106, and the movable plate 62 form a semi-sealed space. When the vacuum cleaner 71 removes dust through the feed pipe 72, a certain degree of negative pressure will be formed on the inside of the semi-sealed space, sucking the liquid glue, thereby accelerating the liquid glue accumulated on the top of the expansion joint to move toward the bottom of the expansion joint. The air grooves on both sides of the baffle 77 can take in air to facilitate dust cleaning, while guiding the liquid glue to quickly fit the expansion joint, speeding up the fitting rate of the liquid glue and the expansion joint while ensuring the quality of the liquid glue after molding.

[0031] Specifically, the cutting member 6 is configured to drive the motor 5 and the cutting blade 13 to move, and to limit the movement of the cleaning member 7 and the driving member 12. The cutting member 6 includes a conduction rod 61, which is fixedly connected to the output end of the motor 5. The cutting blade 13 is detachably connected to the outer side of the conduction rod 61. Two support plates 63 are fixed to the top of the base plate 2. The two support plates 63 are located on both sides of the motor. Hydraulic cylinders 64 are fixed to the tops of the two support plates 63. A movable plate 62 is fixed to the bottoms of the two hydraulic cylinders 64. The motor 5 is fixed to the top of the movable plate 62. Two bases 65 are fixed to the top of the chassis 1. Two limiting rods 66 are fixed to the tops of the bottom walls of the two bases 65, and the movable plate 62 is slidably connected to the outer side of the limiting rods 66.

[0032] In this embodiment, the motor 5 is started, and the motor drives the cutting blade 13 to rotate through the conduction rod 61. Then the staff starts the two hydraulic cylinders 64. The output ends of the two hydraulic cylinders 64 drive the movable plate 62 to move to the side close to the ground. The movable plate 62 moves along the outer side of the four limiting rods 66 to the side close to the ground. The movable plate 62 drives the motor 5 and the cutting blade 13 to move to the side close to the ground. The cutting blade 13 cuts the ground. When the bottom of the movable plate 62 is in contact with the top of the bottom wall of the base 65, the cutting depth of the expansion joint is reached. Then, the driving member 12 drives the device to move to the cutting end point of the expansion joint to complete the cutting of the expansion joint.

[0033] Specifically, the cutting piece 6 also includes a movable groove 69, and a movable groove 69 is penetrated through the top of the base 65 located on the side close to the motor 5 and the vacuum cleaner 71, and a push groove 68 is penetrated through the side of the movable groove 69 close to the limiting rod 66. Two springs four are fixed to the inner side of the movable groove 69, and a clamping rod 67 is fixed to the other end of the two springs four.

[0034] In this embodiment, when the bottom of the movable plate 62 is in contact with the top of the bottom wall of the base 65, the movable plate 62 pushes the push rod 673 to move along the inner side of the push groove 68 toward the side close to the ground, and the push rod 673 drives the clamping rod 67 to squeeze the two springs four and move along the inner side of the movable groove 69 toward the side close to the motor 5. The push rod 673 drives the clamping plate 671 to move out of the inner side of the round rod 104, and the push rod 673 drives the two clamping rings 672 to move out of the inner side of the movable rod 74 and the limit rod 76, thereby releasing the restriction on the round rod 104 and the movable rod 74 and the limit rod 76, and driving the rod 11, the touch plate 111 and the round rod 104 to move toward the side close to the ground. The design of the pulley can prevent the movable rod 74 and the sealing plate from being stuck to the ground.

[0035] Furthermore, the method of use comprises the following steps: The method of use includes the following steps: S1, driving the device to move to the working place by pushing the handle 4 and the driving member 12; S2, start the motor 5 to drive the cutting blade 13 to rotate, and drive the motor 5 and the cutting blade 13 to move toward the ground through the cutting member 6 to cut the ground where the expansion joint needs to be opened; S3, after the cutting is completed, the cutting member 6 releases the restriction on the cleaning member 7 and the driving member 12. When the cleaning member 7 moves to the top of the expansion joint, the cover plate 8 and the cleaning member 7 cooperate with the injection member 10 to clean the inside of the expansion joint; S4. When the injection piece 10 and the nozzle 9 move to the top of the expansion joint, the glue injection into the expansion joint begins. At the same time, the driving piece 12 drives the driving rod 11 and the touch plate 111 to smooth the injected liquid glue.

[0036] Working principle: the staff pushes the handle 4 by hand to start the motor 2 121 and move the device to the work site, then starts the motor 1 5 and the two hydraulic cylinders 64, and the cutting blade 13 cuts the ground. When the bottom of the movable plate 62 fits with the top of the bottom wall of the base 65, the cutting depth of the expansion joint is reached, and then the driving member 12 drives the device to move to the cutting end point of the expansion joint to complete the cutting of the expansion joint. When the bottom of the movable plate 62 fits with the top of the bottom wall of the base 65, the restrictions on the round rod 104, the movable rod 74 and the limit rod 76 are released, and the touch plate 111, the baffle 77 and the movable plate 62 move to the side close to the ground; when the pulley moves to the top of the expansion joint, the cover plate 8 fits with the ground, the baffle 77 and the movable plate 62 move into the inside of the expansion joint, and the vacuum cleaner 71 is started at the same time to clean the expansion joint. When the sealing plate and the driving rod 11 move to the top of the expansion joint, the hydraulic pump 102 is started to move the material tank After the liquid glue in 101 is extracted, it is pumped into the space formed by the inner sealing plate of the expansion joint and the baffles 77 at both ends of the expansion joint through the nozzle 9 to complete the glue injection. When this device moves, the cover plate 8, the fixed plate 106, and the movable plate 62 form a semi-sealed space. When the vacuum cleaner 71 removes dust through the feed pipe 72, a certain degree of negative pressure will be formed inside the semi-sealed space to suck the liquid glue. The output end of the motor 2 121 drives the driving rod 11 to rotate, and the driving rod 11 drives the touch plate 111 to flatten the liquid glue. When the nozzle moves to align with the terminal end of the expansion joint, another fixed plate 106 is fixed to the terminal end of the expansion joint. The liquid glue is confined to the inside of the expansion joint through the two fixed plates 106. The round rod 104, the movable rod 74 and the limit rod 76 are restored to their original positions by hand, and the two hydraulic cylinders 64 are controlled to shrink to their original positions at the same time. The clamping rod 67 again limits the limiting plate 103 and the two movable rods 74, and then waits for the liquid glue to cool.
