Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a construction device for a thick water-stabilized base course for highways. Background Technology

[0002] Water-stabilized layer, also known as cement-stabilized crushed stone layer, is a semi-rigid base material commonly used in road engineering. It is made by mixing crushed stone, cement, and water in a certain proportion, spreading, and compacting. It is widely used in the base or subbase of highways, urban roads, airport runways, and other projects. It has high strength and stability. Construction equipment is required during the construction of water-stabilized layer. Construction equipment refers to the general term for mechanical equipment, tools, temporary facilities, or systems used to complete specific operations in building engineering, civil engineering, or other construction processes.

[0003] The utility model patent application with publication number "CN214497036U" discloses a support device for the construction of cement-stabilized crushed stone base layer, which mainly consists of support plate, support frame, plug plate and locking component. This technical solution solves the problem that the support device is complicated to disassemble and assemble and is inconvenient to store on a daily basis.

[0004] The support device for cement-stabilized crushed stone construction disclosed in the aforementioned document has the following defects: In this technical solution, the springs experience fatigue and elasticity decay after repeated use, which weakens the driving force of the locking block. This results in insufficient automatic locking between the plug plate and the plug slot or incomplete reset after unlocking, leading to loose splicing of the support plate, connection failure, or even inability to disassemble and assemble normally due to jamming of the locking mechanism. This directly affects construction efficiency and structural stability. Since the springs are fixed in the receiving groove with glue and integrated with the locking block, once the springs fail due to fatigue or damage, the support plate must be disassembled and the original adhesive structure destroyed before replacement. This is not only cumbersome and time-consuming, but may also damage other components, increase maintenance costs, and delay the construction progress. Utility Model Content

[0005] The purpose of this utility model is to provide a construction device for a thick water-stabilized base course on highways, which solves the problem that existing springs fail due to fatigue or damage, requiring the removal of the support plate and destruction of the original bonding structure for replacement. This is not only cumbersome and time-consuming, but may also damage other components, increase maintenance costs, and delay the construction progress.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a construction device for a thick water-stabilized base course on highways, comprising a support plate, a support frame installed on one side of the support plate, a insertion groove at one end of the support plate, an insertion plate at the other end of the support plate, an installation hole on the outer surface of the insertion plate, a sealing groove on the outer surface of the support plate, an installation groove on the inner surface of the sealing groove, a locking component inside the installation groove, the locking component comprising a rotating shaft, an installation hole and a limiting groove on the inner surface of the installation groove, one end of the rotating shaft being rotatably connected to the inside of the installation hole, a cam being installed on the outer surface of the rotating shaft, a side plate being installed inside the limiting groove, and two supports being provided on one side of the side plate, with a spring engaging between the two supports, one of the supports being installed on the outer surface of the side plate.

[0008] Furthermore, the cam is located inside the mounting groove, and the outer surface of the other support is in contact with the outer surface of the cam. One end of one of the supports has a threaded hole, and a limit rod is threadedly connected inside the threaded hole. One end of the limit rod passes through the other support and extends into the interior of the insertion groove.

[0009] Furthermore, a sealing plate is fitted inside the sealing groove, and a through hole is opened on the outer surface of the sealing plate. The rotating shaft is rotatably connected inside the through hole, and a gear is installed at the other end of the rotating shaft.

[0010] Furthermore, the outer surface of the sealing plate is provided with two connecting plates, and a worm gear is rotatably connected between the two connecting plates. One end of the worm gear passes through one of the connecting plates and is equipped with a knob. The worm gear meshes with a gear.

[0011] Furthermore, a protective shell is installed on the outer surface of the sealing plate, and the worm gear and gear are both located inside the protective shell.

[0012] Furthermore, each of the two supports has a protrusion at one end.

[0013] This utility model has the following beneficial effects:

[0014] (1) When the rotating shaft of this utility model rotates counterclockwise, the cam gradually releases the compressive force on the spring, and then the limiting rod gradually disengages from the insertion slot, releasing the mechanical limit on the insertion plate. Then the side plate can be directly pulled out from the mounting slot, and the support as a whole can be moved out simultaneously. The axial tension is directly applied to the damaged spring, causing it to disengage from the two support slots. Then the two ends of the new spring are aligned with the slots and pressed in. The entire process does not require disassembling the support plate or damaging the structure, greatly simplifying the maintenance steps and avoiding damage to the components.

[0015] (2) The meshing transmission of the worm gear and gear in this utility model effectively prevents the shaft from rotating unexpectedly when subjected to external vibration or pressure through its self-locking characteristics, ensuring that the cam is always stably in the locked or unlocked position, avoiding the failure of spring pressure or the disconnection of the plug structure due to the loosening of the shaft, thereby maintaining the long-term reliability of the locking component in complex construction environments, and resisting dynamic load interference without additional reinforcement.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-6 As shown, this utility model is a construction device for a thick water-stabilized base course for highways, including a support plate 1. A support frame 2 is installed on one side of the support plate 1. One end of the support plate 1 is provided with an insertion groove 101, and the other end of the support plate 1 is provided with an insertion plate 102. The outer surface of the insertion plate 102 is provided with an installation hole, and the outer surface of the support plate 1 is provided with a sealing groove 103. The inner surface of the sealing groove 103 is provided with an installation groove 104. A locking component 3 is provided inside the installation groove 104. The locking component 3 includes a rotating shaft 301. The inner surface of the installation groove 104 is provided with an installation hole and a limiting groove. One end of the rotating shaft 301 is rotatably connected to the inside of the installation hole. A cam 302 is installed on the outer surface of the rotating shaft 301. A side plate 303 is installed inside the limiting groove. Two supports 304 are provided on one side of the side plate 303. A spring 305 is engaged between the two supports 304. One of the supports 304 is installed on the outer surface of the side plate 303.

[0028] The support frame 2 and the support plate 1 are connected by a plug-in method, which allows for the independent replacement of damaged parts and avoids the whole being scrapped due to local damage;

[0029] Cam 302 is located inside mounting groove 104, and the outer surface of another support 304 contacts the outer surface of cam 302. One end of one support 304 is provided with a threaded hole, and the threaded hole is connected to a limit rod 306. One end of the limit rod 306 passes through the other support 304 and extends into the interior of insertion groove 101.

[0030] The outer contour of cam 302 adopts a gradual curvature design, with a gentle slope in the initial section (efficiency saving) and a steep slope in the final section (force increasing), so that the spring 305 is quickly compressed in the early stage of the locking process and high pressure is applied to lock in the later stage, balancing efficiency and reliability.

[0031] A sealing plate 307 is fitted inside the sealing groove 103. A through hole is opened on the outer surface of the sealing plate 307. A rotating shaft 301 is rotatably connected inside the through hole. A gear 308 is installed at the other end of the rotating shaft 301.

[0032] The outer surface of the sealing plate 307 is provided with two connecting plates 309. A worm gear 3010 is rotatably connected between the two connecting plates 309. One end of the worm gear 3010 passes through one of the connecting plates 309 and is equipped with a knob 3011. The worm gear 3010 is meshed with a gear 308.

[0033] The meshing transmission between the worm gear 3010 and the gear 308 effectively prevents the shaft 301 from rotating unexpectedly when subjected to external vibration or pressure through its self-locking characteristics, ensuring that the cam 302 is always stably in the locked or unlocked position, avoiding the failure of the spring 305 pressure or the disengagement of the plug-in structure due to the loosening of the shaft 301, thereby maintaining the long-term reliability of the locking component 3 in complex construction environments, and resisting dynamic load interference without additional reinforcement;

[0034] A protective shell 4 is installed on the outer surface of the sealing plate 307, and the worm gear 3010 and the gear 308 are both located inside the protective shell 4;

[0035] The protective shell 4 completely encloses the worm gear 3010 and gear 308 through a fully enclosed structure, effectively preventing pollutants such as mud and cement slurry in the construction environment from entering the transmission components, avoiding particles from getting stuck on the meshing tooth surface or corroding the metal surface, and significantly reducing the risk of transmission failure caused by foreign object interference.

[0036] Both supports 304 have a protrusion at one end;

[0037] The protrusions limit the maximum contact distance between the two supports 304 during the compression of the spring 305, forming a rigid physical limit. When the protrusions abut against each other, they prevent the spring 305 from being further compressed and deformed. This avoids plastic deformation or fatigue fracture of the spring 305 due to over-travel compression, and ensures that the locking assembly 3 is always within the preset elastic deformation range, thereby maintaining a stable locking force output and improving the reliability and durability of the device for repeated use.

[0038] In use, the two support plates 1 are initially spliced ​​by aligning and inserting the plug plate 102 into the plug slot 101. Then, the knob 3011 is rotated clockwise to drive the worm gear 3010 to mesh with the gear 308, which drives the rotating shaft 301 to rotate and forces the cam 302 to squeeze the support 304 and compress the spring 305. At the same time, the limiting rod 306 gradually extends into the mounting hole of the plug plate 102 to form a mechanical interlock. Finally, the two support plates 1 are quickly and stably connected by the combined effect of the elastic force of the spring 305 and the rigid constraint of the limiting rod 306.

[0039] When spring 305 needs to be replaced, turn knob 3011 counterclockwise to rotate shaft 301 counterclockwise. Cam 302 gradually releases the compressive force on spring 305. Then, limit rod 306 gradually disengages from mounting hole of plug plate 102, releasing mechanical limit on plug plate 102. Then, seal plate 307 is removed from seal groove 103, allowing shaft 301 to disengage from mounting groove 104. After that, side plate 303 can be directly pulled out from mounting groove 104, simultaneously moving support 304 out as a whole. Axial tension is directly applied to damaged spring 305, causing it to disengage from the slots of the two supports 304. Then, align the two ends of new spring 305 with the slots of support 304 and press it in. The entire process does not require disassembling the connection of the two support plates 1 or damaging the structure, greatly simplifying maintenance steps and avoiding component damage.
