Description

Technical Field

[0001] The present application relates to the technical field of highway crack treatment, and specifically discloses a crack treatment device for highway engineering. Background Art

[0002] Highway cracks are one of the most common problems in pavement diseases. They not only affect the appearance of the road, but may also reduce the service life and safety of the road. Highway cracks are mainly divided into transverse cracks and longitudinal cracks. They may be caused by the asphalt quality not meeting the construction climate requirements or technical standards, resulting in the shrinkage of asphalt concrete, as well as traffic loads, material aging or uneven foundation settlement. For cracks that have already appeared, they can be repaired by grouting, taping or using sealants. These methods are designed to prevent moisture and debris from entering the cracks, delay the expansion of cracks, and thus extend the service life of the road surface;

[0003] At present, most crack treatment devices used in highway projects are large-scale equipment, and the carriers are all movable vehicles. Such devices are easy to use and very convenient for treating large cracks. However, for highway cracks, there are not only large cracks but also small cracks. If the above-mentioned vehicle-type highway crack treatment device is used to treat small cracks, the efficiency will be lower based on the overall size of the small cracks.

[0004] China Publication No. CN220035144U. A highway crack treatment device is disclosed, including a glue spraying mechanism, the glue spraying mechanism includes a glue gun and a glue inlet pipe at the rear end thereof, which is used to be connected to a glue dispensing vehicle, and the outer side of the glue gun is connected to an inclined handle for hand-holding; a supporting mechanism, the supporting mechanism includes a fixed sleeve, the fixed sleeve is connected to the middle section of the glue gun, both sides of the fixed sleeve are connected to threaded rods, both threaded rods are slidably sleeved with support frames, and one side of the two support frames is provided with moving wheels. The utility model adopts threaded limiting of the threaded rod and the threaded sleeve, so that the support frame can be fixed at multiple angles, so that the support frame and the moving wheels can assist in supporting the inclined glue gun. Compared with the prior art, the device has lower arm strength requirements for the staff when in use, and is convenient for the staff to use;

[0005] The above-mentioned highway crack treatment device is a handheld device and is suitable for highway crack treatment, but there are still deficiencies in the treatment mode. For small cracks, since the volume of small cracks is not large enough, the filler may not be able to be saturated and filled. The filler needs time to settle before the saturated filling of small cracks can be achieved. However, the relevant staff do not have this time, and the relevant staff will not wait for the saturated filling time of small cracks to arrive. Therefore, after most small cracks are filled, the plane height formed after the filler settles is lower than the height of the existing road surface, resulting in an overall unsightly appearance. In view of this, the inventor proposes a crack treatment device for highway engineering to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that in the traditional small crack filling and repair process, due to the volume problem of the small crack, the filler may not be able to saturate the crack, thereby resulting in a height difference between the crack and the road surface after the repair.

[0015] Furthermore, a contact portion is provided on the outer periphery of the frame, and the contact portion is a force point for a person to hold the hand.

[0016] Furthermore, the switch assembly includes a connecting cylinder, a threaded cylinder connected to the connecting cylinder, and a rotary switch arranged on the connecting cylinder. The top of the shunt cylinder is provided with a threaded groove, and the threaded groove is threadedly connected to the threaded cylinder.

[0017] Furthermore, the rotary vibration component includes an elastic frame plate, a drainage rod and a rotating rod, the elastic frame plate is fixedly connected to the sleeve, one end of the drainage rod passes through the sleeve and is connected to the rotating rod, a rotating block is provided on the drainage rod located between the elastic frame plates, the rotating block is in contact with the elastic frame plate, and the other end of the drainage rod passes through the collecting assembly for draining the filler.

[0018] Furthermore, the main cylinder is a cylinder with external threads, and the cylinder is a hollow cylinder. The cylinder is threadedly connected to the bottom thread of the diversion cylinder. The upper end and the lower end of the cylinder are respectively provided with an upper cover plate and a lower cover plate. The upper cover plate and the lower cover plate are both provided with bearing mounting grooves, and rotating bearings are placed in the bearing mounting grooves. The main cylinder is threadedly connected to the auxiliary groove, and the surface of the auxiliary groove is provided with a drainage channel used in conjunction with the flow channel. When the collecting assembly is combined with the diversion cylinder, the flow channel and the drainage channel are combined into one.

[0019] Furthermore, the driving assembly includes a motor arranged on the lower cover plate, a driving gear coaxially connected to the motor output shaft, and a driven gear meshing with the driving gear, and a first mounting point, a second mounting point and a third mounting point are respectively provided on the drainage rod, the first mounting point and the third mounting point are used to install the rotating bearing, and the second mounting point is used to install the driven gear.

[0020] Furthermore, the outer surface of the auxiliary groove is provided with a connecting thread, and a collecting tube is connected via the connecting thread. The collecting tube consists of a straight tube and an inclined tube. The straight tube is used to be threadedly connected to the connecting thread, and the inclined tube is inclined toward the direction of the bearing mounting groove.

[0021] Furthermore, a connecting groove is formed at the end of the drainage rod close to the collecting assembly, and a drainage rod is detachably connected to the connecting groove.

[0022] Furthermore, the filler is polyurethane sealant.

[0023] The principle and effect of this scheme are:

[0024] 1. Compared with the prior art, the present invention is a handheld device. Compared with the traditional vehicle-type crack treatment device for highway engineering, the entire device is simpler and more convenient to use. This device is a special device for filling small cracks and has a good effect on small cracks on the highway.

[0025] 2. Compared with the prior art, this device and the traditional vehicle-type crack treatment device for highway engineering complement each other, and they complement and achieve each other. The traditional vehicle-type crack treatment device for highway engineering acts on large cracks on the highway, and adopts a pouring mode to quickly fill the highway cracks. This device acts on small cracks on the highway, and adopts a refined filling method to fill and repair small cracks on the highway.

[0026] 3. Compared with the prior art, the core of the present device is drainage. A drainage rod is provided, which assists the filler to reach the bottom of the crack, thereby achieving saturated filling of the crack with the filler. In this process, the present device adopts a technical solution in which the drainage rod and the filler are first separated and then converged. This technical solution can prevent the effects of the drainage rod and the filler from affecting each other. Since the drainage rod and the filler will finally converge, the drainage effect of the drainage rod can be utilized to achieve the filler reaching the bottom of the crack, ultimately solving the problem of traditional small crack filling and repair, where the filler may not be able to saturate the crack due to the volume problem of the small crack, resulting in a height difference between the filler and the road surface after the repair.

[0027] 4. Compared with the prior art, in order to accelerate the filling of the cracks with the filler, the present device is not only provided with a drainage rod to achieve drainage, but also provided with a driving assembly based on the drainage rod. Based on the action of the driving assembly, the drainage rod is allowed to rotate at a low speed. Since the drainage rod and the filler will eventually converge, the rotating drainage rod can act on the filler, thereby achieving dynamic filling of the filler and slowing down the filling of the cracks with the filler.

[0028] 5. Compared with the prior art, the low-speed rotation of the drainage rod brought about by the setting of the driving component realizes the vibration of the filler when it falls. When the filler can vibrate when falling, the filler can be accelerated to fall and the clogging of the filler can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Implementation example Figure 1-Figure 6 As shown:

[0039] A crack treatment device for highway engineering, comprising:

[0040] Material barrel 1: the interior is filled with filler for crack repairing, and a switch assembly is provided at the bottom of the material barrel 1;

[0041] The flow dividing cylinder 5 is detachably connected to the bottom of the material cylinder 1. A sleeve 21 is fixedly connected to the bottom of the flow dividing cylinder 5. A flow channel 22 is formed between the sleeve 21 and the inner wall of the flow dividing cylinder 5. The top of the sleeve 21 is connected to a rotating vibration component acting on the filler.

[0042] Collection component: detachably connected to the diversion cylinder 5, the collection component includes a main cylinder 14 and a secondary groove 15 detachably connected to the main cylinder 14, a driving component for rotating the vibration component is provided inside the main cylinder 14, and the secondary groove 15 cooperates with the flow channel 22 to allow the filler to flow out;

[0043] The rotary vibration component is used in conjunction with the collecting component to drain the filler, and the external part of the auxiliary tank 15 is detachably connected with a drainage plate;

[0044] Moving component: It is detachably connected to the outside of the diversion tube 5. When the moving component is manually pushed, the diversion tube 5 is driven to move based on the direction of the crack.

[0045] About mobile components:

[0046] The moving assembly includes an iron ring 7 fixed to the outside of the diverter tube 5, a frame 8, a plurality of support legs 10 arranged at the bottom of the frame 8, a mounting groove 11 opened on the support leg 10, a universal wheel installed on the mounting groove 11, a groove 12 opened on the frame 8, a boss 13 arranged on the groove 12 and a magnet sheet installed on the boss 13. The iron ring 7 is placed on the boss 13 and is magnetically connected to the magnet sheet.

[0047] Specific:

[0048] Since the direction of the crack is irregular, a moving component is set up based on this, and the moving component is used to assist the device in moving and filling, thereby saving more effort, and the device is moved based on the direction of the crack through the universal wheel;

[0049] In this process, the iron ring 7 is placed on the boss 13 and magnetically connected to the magnet sheet to achieve stable installation of the device. After stable installation, the movement of the moving component represents the movement of the device.

[0050] Since the moving assembly needs to be pushed manually, a contact portion 9 is provided on the periphery of the frame 8. The contact portion 9 is a force point for manual hand-holding. The contact portion 9 provides a force point to push the moving assembly to move.

[0051] like Figure 1 As shown:

[0052] The switch assembly comprises a connecting cylinder 2 , a threaded cylinder 4 connected to the connecting cylinder, and a rotary switch 3 arranged on the connecting cylinder. A threaded groove 6 is arranged on the top of the shunt cylinder 5 , and the threaded groove 6 is threadedly connected to the threaded cylinder 4 .

[0053] The rotary switch 3 is a mechanical switch. The flow of the filler is realized by turning the rotary switch 3 on or off. The interior of the material cylinder 1 is filled with the filler for crack repair. The filler enters the threaded cylinder 4 through the connecting cylinder 2 and enters the diverter cylinder 5 through the threaded cylinder 4.

[0054] After entering the diversion tube 5, it is acted upon by the rotating vibration assembly, specifically:

[0055] like Figure 4 As shown:

[0056] The rotary vibration assembly includes an elastic frame plate 28, a drainage rod 18 and a rotating rod 25. The elastic frame plate 28 is fixed to the sleeve 21. One end of the drainage rod 18 passes through the sleeve 21 and is connected to the rotating rod 25. A rotating block 26 is provided on the drainage rod 18 located between the elastic frame plates 28. The rotating block 26 is in contact with the elastic frame plate 28. The other end of the drainage rod 18 passes through the collecting assembly for draining the filler.

[0057] In order to enhance the installation strength of the sleeve 21 , a bracket 27 is provided on the sleeve 21 , and the other end of the bracket 27 is fixedly connected to the inner wall of the diverter tube 5 .

[0058] The elastic frame plate 28 allows the filler to flow left and right. Since the drainage rod 18 rotates, the rotating rod 25 rotates, so that the filler does not accumulate into blocks and flows, and the filler flows in a dispersed manner. After being diverted left and right by the elastic frame plate 28, it flows out from the flow channel 22. In this process, since the drainage rod 18 rotates and the rotating block 26 contacts the elastic frame plate 28, the rotating block 26 acts on the elastic frame plate 28, causing the elastic frame plate 28 to vibrate, accelerating the flow of the filler on the elastic frame plate 28, and finally the filler enters the flow channel 22.

[0059] The filler enters the flow channel 22 and then enters the collection component:

[0060] About the collection component:

[0061] The main cylinder 14 is a cylinder with external threads, which is a hollow cylinder. The cylinder is threadedly connected to the bottom thread of the diversion cylinder 5. The upper end and the lower end of the cylinder are respectively provided with an upper cover plate 31 and a lower cover plate 32. The upper cover plate 31 and the lower cover plate 32 are both provided with bearing mounting grooves 33. Rotating bearings 19 are placed in the bearing mounting grooves 33. The main cylinder 14 is threadedly connected to the auxiliary groove 15. The surface of the auxiliary groove 15 is provided with a drainage channel 17 used in conjunction with the flow channel 22. When the collecting assembly is combined with the diversion cylinder 5, the flow channel 22 and the drainage channel 17 are combined into one.

[0062] In order to enhance the stability of the flow channel 22 , a reinforcing rib 16 is provided in the flow channel 22 , and the reinforcing rib 16 divides the flow channel 22 into a plurality of independent small areas.

[0063] Specific:

[0064] The filler enters the flow channel 22 and then enters the drainage channel 17, and flows out from the bottom of the drainage channel 17. During this process:

[0065] like Figure 6 As shown, the driving assembly includes a motor 34 arranged on the lower cover plate 32, a driving gear 35 coaxially connected to the output shaft of the motor 34, and a driven gear 20 meshing with the driving gear 35, and the drainage rod 18 is respectively provided with a first mounting point, a second mounting point and a third mounting point, the first mounting point and the third mounting point are used to install the rotating bearing 19, and the second mounting point is used to install the driven gear 20.

[0066] When the motor 34 is started, the driving gear 35 is driven to rotate. When the driving gear 35 rotates, the driving gear 35 meshes with the driven gear 20, so that the driven gear 20 rotates. When the driven gear 20 rotates, the drainage rod 18 rotates.

[0067] The rotating bearing 19 is to ensure that the drainage rod 18 can rotate stably;

[0068] The outer surface of the auxiliary groove 15 is provided with a connecting thread 29 , and a collecting tube 30 is connected via the connecting thread 29 . The collecting tube 30 consists of a straight tube and an inclined tube. The straight tube is used for threaded connection with the connecting thread 29 , and the inclined tube is inclined toward the direction of the bearing mounting groove 33 .

[0069] The purpose of the tilting cylinder is to change the direction of the filler flowing out from the bottom of the drainage channel 17 and approach the drainage rod 18, thereby achieving drainage with a small rotation speed of the drainage rod 18 and accelerating the filling of the cracks;

[0070] Since some cracks are too small, in order to improve the applicability of the present device, a connecting groove 36 is opened at the end of the drainage rod 18 near the collecting component, and a guide stick is detachably connected to the connecting groove 36. The guide stick is threadedly connected to the connecting groove 36. The guide stick is of small size, and the small-sized guide stick is suitable for use in the process of filling and repairing smaller cracks.

[0071] The filler in the whole scheme is polyurethane sealant, which belongs to the room temperature chemical caulking material, and its main components include isocyanate, polyol, etc. It is characterized by fast curing speed and can reach high strength in a short time; it has good oil resistance, corrosion resistance and wear resistance, and is suitable for sealing various concrete pavements, bridge expansion joints, etc.

[0072] Specific implementation process:

[0073] Step 1, normal as 1- Figure 6 Install the device as shown, and select the appropriate size of the guide rod based on the size of the crack;

[0074] The second step is to insert the end of the guide stick or drainage rod 18 into the bottom of the crack, and then turn on the rotary switch 3, and the filler starts to flow from top to bottom;

[0075] In the third step, the filler flows out from the bottom of the drainage channel 17, and is affected by the inclined cylinder so that the flow direction of the filler is close to the drainage rod 18 or the drainage stick. Since the end of the drainage stick or the drainage rod 18 is inserted into the bottom of the crack, the filler at this time starts from the bottom of the crack and gradually fills upward;

[0076] Step 4: During the filling process, the guide stick or drainage rod 18 rotates to accelerate the dispersion of the filler, so that the filler is dynamically filled instead of the traditional free diffusion of the filler. Compared with the traditional free diffusion of the filler, the filling speed is faster;

[0077] Moreover, along with the rotation of the guide rod or drainage rod 18, the filler will be affected by the dispersing effect of the rotating rod 25 and the vibration effect of the rotating block 26 during the flow from top to bottom. The dispersing effect of the rotating rod 25 and the vibration effect of the rotating block 26 promote the flow of the filler from top to bottom and accelerate the outflow of the filler.

[0078] The device solves the problem that in traditional small crack filling and repair, due to the volume problem of small cracks, the filler may not be able to saturate the cracks, resulting in a height difference between the cracks and the road surface after repair.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
