Description

Technical Field

[0001] This utility model relates to the field of road repair construction technology, specifically to an automatic filling gun head for road crack sealant suitable for different crack widths. Background Technology

[0002] Crack filling is a common operation in road maintenance and repair, effectively preventing further expansion of road cracks and extending the service life of the road surface. However, traditional crack filling methods have several drawbacks. Firstly, most existing crack filling equipment requires prolonged hand-held operation, leading to high labor intensity and operator fatigue, thus affecting efficiency and quality. Furthermore, the fixed size of the injection tube makes it difficult to accurately adapt to cracks of varying widths. A tube that is too narrow cannot fill wider cracks, resulting in insufficient filling; a tube that is too wide wastes adhesive, increasing construction costs. Secondly, there is a lack of effective control measures to prevent adhesive overflow and waste during the filling process, and it is difficult to accurately determine whether the crack has been fully filled. This can lead to insufficient filling of some cracks, affecting the repair effect, or excessive adhesive overflow, resulting in material waste and environmental pollution. Therefore, it is essential to develop an automatic crack filling nozzle suitable for different crack widths to address the problems of inconvenient operation, inability to adapt to different crack widths, easy adhesive overflow and waste, and difficulty in determining whether the filling is sufficient in existing technologies. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides an automatic filling gun head for road crack sealant suitable for different crack widths, which can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: An automatic filler nozzle for road crack sealing adhesive suitable for different crack widths includes a top plate base. The bottom of the top plate base is equipped with casters around its perimeter. The bottom of the top plate base is elastically connected to a pressure plate via a spring structure. A circular ring plate is fixedly installed in the center of the pressure plate. Several seepage holes are circumferentially formed on the surface of the circular ring plate. A transparent support platform is installed in the center of the top plate base. An adhesive injection tube is threaded through the center of the transparent support platform. A variable-diameter injection head is integrally formed at the bottom of the adhesive injection tube. A spring is fitted in the center of the adhesive injection tube. The top of the adhesive injection tube is connected to the crack sealing adhesive tube via a threaded connector. A through hole is formed in the center of the circular ring plate to accommodate the insertion of the adhesive injection tube. A handrail is fixedly installed on the top of the top plate base.

[0005] Furthermore, the variable diameter dispensing head includes several tubes with progressively increasing diameters from bottom to top, with adjacent tubes connected by a tapered tube.

[0006] Furthermore, the transparent support platform includes a cross-shaped support frame, and tempered glass is fixedly installed in the space between the cross-shaped support frame and the top plate seat.

[0007] Furthermore, a clamp A is attached to the middle of the injection tube, the bottom of the spring is supported on the surface of clamp A, and the top of the spring is attached to the bottom of the transparent support platform.

[0008] Furthermore, a clamp B is attached to the top of the injection tube, and clamp B is located between the transparent support platform and the threaded joint.

[0009] Furthermore, both sides of the pressure plate are integrally formed with arc-shaped end faces, and the bottom of the pressure plate is 3mm~5mm lower than the bottom of the caster wheel.

[0010] The beneficial effects of this utility model are as follows: The device of this application is connected to the injection tube through the grouting tube. The injection tube is elastically installed on the top plate seat with wheels, so it does not need to be held for a long time. At the same time, the bottom of the injection tube is provided with multiple sizes. When the injection tube moves in the gap, it adapts to the size of the gap by adjusting the injection tube with the spring. It can adapt to different crack widths. Meanwhile, a pressure plate is added around the injection tube. The pressure plate can reduce the overflow and waste of the potting compound after it fills the gap. At the same time, seepage holes and exposed support platforms are added. By observing whether the potting compound overflows, it can be determined whether the gap is filled. This ensures that the gap is filled fully while reducing the waste of the compound. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figure 1-3 As shown, this utility model discloses an automatic filling gun head for road crack sealant suitable for different crack widths, including a top plate seat 1. Universal wheels 9 are provided around the bottom of the top plate seat 1. The bottom of the top plate seat 1 is elastically connected to a pressure plate 2 via a spring structure 8. A circular ring plate 10 is fixedly installed in the middle of the pressure plate 2. Several seepage holes 11 are circumferentially formed on the surface of the circular ring plate 10. A transparent support platform 4 is provided in the middle of the top plate seat 1. An injection tube 3 is inserted through the middle of the transparent support platform 4. A variable diameter injection head 301 is integrally formed at the bottom of the injection tube 3. A spring 13 is sleeved in the middle of the injection tube 3. The top end of the injection tube 3 is connected to a crack sealant tube 6 via a threaded connector 5. A through hole 1001 is provided in the middle of the circular ring plate 10 to accommodate the injection tube 3. A handrail 7 is fixedly installed on the top of the top plate seat 1.

[0017] Example 1: The spring structure 8 includes a spring in the middle and flange covers at both ends. The spring of the spring structure 8 is welded and fixed to the flange covers at both ends. The two flange covers are fixed to the pressure plate 2 and the top plate seat 1 by bolts. The reducing nozzle 301 at the bottom of the injection tube 3 is composed of tubes with progressively increasing diameters from bottom to top. The diameter of the injection tube 3 is set to 30mm, and from top to bottom, the diameters are 28mm, 26mm, 24mm, 22mm, 20mm, and 18mm. The tubes are connected by tapered tubes. The diameter of the through hole 1001 of the ring plate 10 is the same as the diameter of the glue injection tube 3, both being 30mm. When the spring of the spring structure 8 is in a naturally extended state, the bottom of the pressure plate 2 is lower than the bottom of the universal wheel 9, so that when the universal wheel 9 contacts the ground, the pressure plate 2 can press against the ground. The grouting hose 6 is connected to the grouting supply equipment, which includes a grout tank, a grout pump, and a heating device, and is used to deliver the grouting adhesive into the grouting hose 6. The handrail 7 is used to control the movement of the top plate seat 1.

[0018] In the preferred technical solution, the variable diameter dispensing head 301 includes several tubes with progressively increasing diameters from bottom to top, and adjacent tubes are connected by a tapered tube.

[0019] In the preferred technical solution, the transparent support platform 4 includes a cross-shaped support frame. Tempered glass is fixedly installed in the space between the cross-shaped support frame and the top plate seat 1. The cross-shaped support frame is used to support the tempered glass and for the insertion of the glue injection tube 3. The tempered glass is used to observe the glue overflow from the seepage hole 11.

[0020] In the preferred technical solution, a clamp A12 is snapped into the middle of the glue injection tube 3, the bottom of the spring 13 is supported on the surface of the clamp A12, and the top of the spring 13 is attached to the bottom of the transparent support platform 4. The clamp A12 and the spring 13 are used to realize the adaptive lifting and lowering of the glue injection tube 3.

[0021] In the preferred technical solution, a clamp B14 is attached to the top of the glue injection tube 3. The clamp B14 is located between the transparent support platform 4 and the threaded joint 5. The clamp B14 is used to limit the descent range of the glue injection tube 3.

[0022] In the preferred technical solution, both sides of the pressure plate 2 are integrally formed with arc end faces, which facilitates the movement of the pressure plate 2 on the ground and reduces resistance. The bottom of the pressure plate 2 is 3mm~5mm lower than the bottom of the universal wheel 9, so that when the universal wheel 9 contacts the ground, the pressure plate 2 can press against the ground.

[0023] In practical use, the variable diameter injection head 301 of the injection tube 3 is placed into the gap. When the gap is small, the injection tube 3 rises adaptively and the spring 13 is compressed. When the gap is large, the injection tube 3 falls adaptively and the spring 13 rebounds. The bottom of the pressure plate 2 is lower than the bottom of the caster 9, so that when the caster 9 contacts the ground, the pressure plate 2 can press against the ground. When injecting glue, the variable diameter injection head 301 outputs the potting glue. When the gap is full, the potting glue will overflow from the seepage hole 11. When the glue overflows from the seepage hole 11, the moving device moves the injection head 301 in the gap to fill the subsequent gaps, thereby ensuring that the gap is fully filled while reducing glue waste.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
