Description

Technical Field

[0001] This utility model relates to the field of road repair technology, specifically a crack sealing machine for road crack repair. Background Technology

[0002] A crack sealing machine, also known as a crack sealing truck, is a professional piece of equipment used for repairing road surface cracks. It is mainly used to accurately and efficiently apply crack sealing tape to road surface cracks to prevent rainwater, mud and other debris from entering the cracks and to slow down the development of road surface defects. It is mainly suitable for crack repair and maintenance of various roads such as asphalt pavement and cement pavement.

[0003] Traditional crack sealing machines lack a cutting mechanism. After a section of the road surface is paved, if there is any excess crack sealing tape on the material rack, workers need to use a knife to cut it, which is cumbersome and difficult to control the force, and is extremely easy to cause scratches. Therefore, a crack sealing machine for road surface crack repair is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve at least one technical problem in the background technology, this utility model proposes a crack sealing machine for road surface crack repair.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a crack patching machine for road surface repair, comprising a main frame, a limiting plate fixedly connected to the main frame, and a crack patching tape reel rotatably connected to the surface of the limiting plate.

[0006] A pressure roller is rotatably connected to the surface of the main frame, and a winding roller is rotatably connected to the surface of the main frame via a spring;

[0007] An adjustment mechanism is provided, wherein guide rods are mounted on the surface of the main frame via the adjustment mechanism;

[0008] A support rod, which is fixedly connected to the main frame, and multiple brackets are fixedly connected to the surface of the support rod;

[0009] A base plate is fixedly connected to the surface of the support rod, an arc-shaped plate is fixedly connected to the surface of the base plate, a pressure plate is rotatably connected to the surface of the support rod via a torsion spring, a blade is fixedly connected to the surface of the pressure plate, and a top plate is fixedly connected to the surface of the base plate.

[0010] A pressure rod is rotatably connected to the surface of the main frame, and a pull rope is fixedly connected to the surface of the pressure plate. The other end of the pull rope passes through the bracket and is slidably connected, and the end is fixedly connected to the surface of the pressure rod.

[0011] Preferably, a pull ring is fixedly connected to the surface of the pressure rod, and the pressure rod and the main frame form an approximate triangle.

[0012] Preferably, a spring sheet is fixedly connected to the surface of the pressure plate, and the other end of the spring sheet is a free end. When the pressure plate rotates and squeezes the seam tape, the spring sheet will also contact the seam tape to fix it. At the same time, by keeping the spring sheet in contact with the surface of the seam tape, it can also achieve the effect of a simple tensioning wheel to tighten the seam tape and avoid stacking.

[0013] Preferably, the adjustment mechanism includes a slot, which is formed inside the main frame. A slide plate is slidably connected to the slot via a spring. A retaining shaft is fixedly connected to the surface of the slide plate. A retaining groove is formed on the surface of the guide rod relative to the retaining shaft. The top of the retaining shaft is an arc surface.

[0014] Preferably, a rotating shaft is rotatably connected to the inner wall of the empty slot. One end of the rotating shaft passes through the side wall of the empty slot and is rotatably connected. A locking block is threaded onto the surface of the rotating shaft. The end of the locking block is chamfered. A knob is fixedly connected to the part of the rotating shaft outside the main frame. An anti-slip pad is fixedly connected to the surface of the knob. The anti-slip pad can increase the friction of the worker's hand, thereby making it easier to turn the knob and avoiding slippage.

[0015] Preferably, a wheel frame is fixedly connected to the surface of the main frame. There are two wheel frames, and a pair of wheel frames are symmetrically distributed about the central axis of the main frame. Each wheel frame surface is rotatably connected to a support wheel.

[0016] The advantages of this utility model are:

[0017] 1. This utility model uses a pull rope to pull the pressure plate, which in turn drives the blade to cut the joint tape. After the local road surface is paved, it can be quickly cut, replacing the need for workers to use hand-held knives to cut the tape. This simplifies the process, makes the operation convenient, and effectively reduces the risk of scratches.

[0018] 2. This utility model uses a spring for temporary positioning, while the retaining pin remains in the slot. When the guide rod is pulled, the retaining pin bounces indirectly, which can increase the feel of the operator when sliding and also assist in positioning, making it easy to adjust to a suitable height. Through the design of the adjustment mechanism, the height of the guide rod can be adjusted according to different users, thereby improving the applicability of the device and indirectly improving its practicality.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1-6 As shown, a crack sealing machine for road surface repair includes a main frame 1, a limiting plate 8 is fixedly connected to the main frame 1, and a sealing tape 7 disc is rotatably connected to the surface of the limiting plate 8.

[0031] A pressure roller 2 is rotatably connected to the surface of the main frame 1, and a winding roller 3 is rotatably connected to the surface of the main frame 1 via a spring;

[0032] Adjustment mechanism 12, guide rod 16 is installed on the surface of main frame 1 through adjustment mechanism 12;

[0033] Support rod 28 is fixedly connected to the main frame 1, and multiple brackets are fixedly connected to the surface of support rod 28.

[0034] A base plate 5 is fixedly connected to the surface of the support rod 28, an arc plate is fixedly connected to the surface of the base plate 5, a pressure plate 6 is rotatably connected to the surface of the support rod 28 via a torsion spring, a blade 29 is fixedly connected to the surface of the pressure plate 6, and a top plate 31 is fixedly connected to the surface of the base plate 5.

[0035] A pressure rod 13 is rotatably connected to the surface of the main frame 1, and a pull rope 9 is fixedly connected to the surface of the pressure plate 6. The other end of the pull rope 9 passes through the bracket and is slidably connected, and the end is fixedly connected to the surface of the pressure rod 13. A pull ring is fixedly connected to the surface of the pressure rod 13. The pressure rod 13 and the main frame 1 form an approximate triangle. A spring piece 27 is fixedly connected to the surface of the pressure plate 6. The other end of the spring piece 27 is a free end.

[0036] During operation, the seam sealing tape 7 is installed on the limiting plate 8. Then, the open end of the seam sealing tape 7 is passed between the pressure plate 6 and the fixed plate, and then between the pressure roller 2 and the winding roller 3. The protective film on the seam sealing tape is wound onto the winding roller 3. The seam sealing tape 7 is then placed under the pressure roller 2. At this point, the guide rod 16 can be pushed. Through the friction between the seam sealing tape and the pressure roller 2, the seam sealing tape 7 is continuously output to seal the gaps to be repaired. After use, the pressure rod 13 is pulled, causing the pressure rod 13 to drive the pull rope 9. The pull rope 9 pulls the pressure plate 6, and simultaneously, the blade 29 on the surface of the pressure plate 6 moves towards the seam sealing tape 7, and, in conjunction with the top plate 31, cuts the seam sealing tape 7. The method of using rope 9 to pull pressure plate 6 and drive blade 29 to cut the joint tape 7 allows for quick cutting after local road surface paving is completed, replacing manual cutting with a knife, simplifying the process, making operation convenient, and effectively reducing the risk of scratches. After pressure bar 13 is attached to main frame 1, the main frame 1 and pressure bar 13 form a triangle. Under the force of torsion spring, pressure plate 6 drives rope 9 to continuously pull pressure plate 6, keeping pressure plate 6 attached to main frame 1, thus preventing automatic reset. At the same time, because the spring piece 27 fixedly connected to the surface of pressure plate 6, in conjunction with the arc plate, can fix the end of the cut joint tape 7, preventing it from swinging around randomly and facilitating the next use.

[0037] The adjustment mechanism 12 includes a slot 21, which is located inside the main frame 1. A slide plate 18 is slidably connected to the slot 21 via a spring. A retaining shaft 19 is fixedly connected to the surface of the slide plate 18. A retaining groove 17 is provided on the surface of the guide rod 16 relative to the retaining shaft 19. The top of the retaining shaft 19 is an arc surface. A rotating shaft 22 is rotatably connected to the inner wall of the slot 21. One end of the rotating shaft 22 passes through the side wall of the slot 21 and is rotatably connected. A retaining block 23 is threadedly connected to the surface of the rotating shaft 22. The end of the retaining block 23 is chamfered. A knob is fixedly connected to the part of the rotating shaft 22 outside the main frame 1. An anti-slip pad is fixedly connected to the surface of the knob.

[0038] During operation, rotating the shaft 22 causes the threads on its surface to move the two locking blocks 23 away from each other, disengaging them from the slide plate 18. At this point, the locking blocks 23 release their positioning of the locking shaft 19, allowing the guide rod 16 to be pulled out. When the guide rod 16 is pulled upwards, the locking groove 17 presses against the arc surface of the locking shaft 19, forcing the locking shaft 19 to move away from the locking groove 17. Once the guide rod 16 reaches the designated position, the locking shaft 19 will re-engage in the locking groove 17 for positioning. Then, rotating the knob causes it to rotate the rod, which in turn moves the two locking blocks 23 closer together until they are above the slide plate 18. The skateboard 18 is positioned to prevent the guide rod 16 from sliding freely under external force. Rotating the pivot 22 only contacts the positioning of the skateboard 18. At this time, under the action of the spring, the locking pin 19 will not disengage from the locking groove 17. The spring provides temporary positioning, and the locking pin 19 is always in the locking groove 17. When the guide rod 16 is pulled, the locking pin 19 bounces indirectly, which can also improve the feel of the operator when sliding. At the same time, it assists in positioning and makes it easy to adjust to a suitable height. Through the design of the adjustment mechanism 12, the height of the guide rod 16 can be adjusted according to different users, thereby improving the applicability of the device and indirectly improving its practicality.

[0039] Example 2

[0040] Please see Figure 7 As shown in the first embodiment, as another implementation of this utility model, a wheel frame 32 is fixedly connected to the surface of the main frame 1. There are two wheel frames 32, and the pair of wheel frames 32 are symmetrically distributed about the central axis of the main frame 1. Each wheel frame 32 is rotatably connected to a support wheel 33. During operation, the support wheels 33 on both sides can change the single wheel contact with the ground to three wheels contacting the ground, thereby improving the stability of the device during use. It also makes it easier for the worker to press down the pressure wheel 2, so that the sealing tape 7 fits the ground better. When not in use, it can be placed stably, which greatly reduces the physical strength required for the worker to use the sealing machine, thereby indirectly improving work efficiency.
