Description

Technical Field

[0001] The utility model belongs to the technical field of cement stabilized macadam pavements, and particularly relates to a height-fixing component for laying cement stabilized macadam pavements. Background Technique

[0002] Cement stabilized macadam uses graded macadam as aggregate, adopts a certain amount of cementitious materials and sufficient mortar volume to fill the voids of the aggregate, and is paved and compacted according to the interlocking principle. It has high initial strength, and the strength increases rapidly with the age and forms a slab, so it has relatively high strength, good impermeability and frost resistance. During the laying process of cement stabilized macadam pavements, in order to ensure the smoothness of the laying, height-fixing components are usually installed to ensure the accuracy of the laying thickness and the construction efficiency. However, it still has the following disadvantages in actual use:

[0003] After the height-fixing component is installed at the bottom of the laying device, the laying device moves to make the height-fixing component scrape off the excess laying materials, and the excess laying materials fill the places with insufficient thickness, so that the laying base reaches the specified thickness. Then, the road surface is compacted by a rolling device. However, due to the limited lengths of the laying device and the height-fixing component, the excess materials often overflow from both sides and the top of the height-fixing component during laying, and subsequent cleaning is required, reducing the construction efficiency;

[0004] During the laying of the road surface, due to the differences in the thickness of the cement stabilized macadam base required for laying at different positions of the road surface, when using the height-fixing component for height-fixing, it is necessary to adjust its height, which is time-consuming and laborious. Content of the Utility Model

[0005] The purpose of the utility model is to provide a height-fixing component for laying cement stabilized macadam pavements. Through the height-fixing support frame and the mounting plate, the problems that in the use of the height-fixing component for laying cement stabilized macadam pavements, due to the limited length of the height-fixing component, the excess materials often overflow from both sides and the top of the height-fixing component during laying, subsequent cleaning is required, reducing the construction efficiency, and when adjusting the laying thickness, it is necessary to adjust the height of the height-fixing component, which is time-consuming and laborious, are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a height-fixing component for laying cement stabilized macadam pavements, which includes a height-fixing support frame and a mounting plate. A height-fixing scraper is welded and fixed on one side of the height-fixing support frame. A rotating motor is clamped and fixed at one end of the height-fixing support frame. The mounting plate is arranged at the top of the height-fixing support frame, and a lifting cylinder is clamped at the bottom of the mounting plate;

[0008] The height-fixed scraper can block excessive materials laid on the ground by the laying device and make the excess materials fill the places with insufficient thickness, ensuring the construction efficiency. The excessive scraped materials can enter the height-fixed support frame for collection as the laying device moves, and the rotation of the spiral feeding component is driven by the rotation motor to convey the excess materials to the material bucket or other positions, without the need to clean the road surface, improving the use efficiency. After the mounting plate is installed at the bottom of the laying device, the infrared distance measuring component can monitor the distance between the mounting plate and the ground, and further obtain the distance between the bottom of the height-fixed support frame and the ground. The height-fixed support frame can be driven by the lifting cylinder to move up and down to adjust the height of the height-fixed support frame, laying cement stabilized macadam bases with different thicknesses, which is simple and convenient to operate and can be applied to laying devices of different models, improving the flexibility of use.

[0009] Further, one end of the height-fixed support frame is penetrated and clamped with a metal bellows. The metal bellows is located at the other end of the height-fixed support frame relative to the rotation motor. A material passing port is penetrated and opened on one side of the height-fixed support frame. The height-fixed scraper is located at the center of the bottom of the material passing port.

[0010] When the laying device drives the height-fixed scraper to move, the height-fixed scraper can block excessive materials laid on the ground by the laying device and make the excess materials fill the places with insufficient thickness, ensuring the construction efficiency. The overflowing materials can enter the height-fixed support frame through the material passing port at both ends and the top of the height-fixed scraper for collection, avoiding pollution to other areas of the ground and eliminating the need for subsequent cleaning, improving the construction efficiency.

[0011] Further, one end of the rotation motor is clamped with a rotating rod. The outer peripheral surface of the rotating rod is welded and fixed with a spiral feeding component. The rotating rod is penetrated and inserted into one end of the height-fixed support frame. The spiral feeding component is located inside the height-fixed support frame.

[0012] Driving the rotation of the rotating rod and the spiral feeding component by the rotation motor can make the excess raw materials entering the height-fixed support frame enter the metal bellows and be conveyed to other devices through the metal bellows, facilitating the reuse or centralized treatment of the excess raw materials.

[0013] Further, the bottom of the lifting cylinder is slidably clamped with a telescopic rod. The telescopic rod is clamped at the top of the height-fixed support frame.

[0014] When adjusting the height of the height-fixed component, according to the thickness of the cement stabilized macadam base to be laid on the road surface, control the lifting cylinder to drive the telescopic rod to expand and contract, further adjust the height of the height-fixed support frame, and control the laying thickness, which is simple and convenient to operate.

[0015] Further, mounting holes are perforated through the four sides of the top of the mounting plate. One side of the bottom of the mounting plate is fixedly connected with an infrared ranging component, and the height-setting scraping plate is located between the height-setting support frame and the infrared ranging component;

[0016] After the mounting plate is fixed to the bottom of the paving device by passing bolts through the mounting holes, the infrared ranging component can monitor the distance between the mounting plate and the ground, and further obtain the distance between the bottom of the height-setting support frame and the ground, which is convenient for adjusting the height of the height-setting support frame and can be applicable to paving devices of different models, improving the flexibility of use.

[0017] The utility model has the following beneficial effects:

[0018] By setting the height-setting support frame in the utility model, after the height-setting component is installed at the bottom of the paving device, the height-setting component levels the excess paving material through the movement of the paving device, and the excess paving material fills the places with insufficient thickness, so that the paving base layer reaches the specified thickness. Then, the road surface is compacted by the rolling device. However, due to the limited lengths of the paving device and the height-setting component, the excess material often overflows from both sides and the top of the height-setting component during paving, and subsequent cleaning is required, reducing the construction efficiency. When the height of the paving material is set by the height-setting scraping plate, the excess material enters the height-setting support frame through both ends and the top of the height-setting scraping plate for collection, avoiding the pollution of other positions on the road surface caused by the overflow of the excess material. The rotating motor drives the rotating rod and the spiral feeding component to rotate, enabling the excess raw material entering the height-setting support frame to enter the metal corrugated pipe and be transported to other devices through the metal corrugated pipe, facilitating the reuse or centralized treatment of the excess raw material and avoiding the waste of materials.

[0019] By setting the mounting plate in the utility model, when paving the road surface, due to the differences in the thickness of the cement stabilized macadam base layer required for paving at different positions of the road surface, when using the height-setting component for height setting, it is necessary to adjust its height, and the operation is time-consuming and laborious. After the mounting plate is installed at the bottom of the paving device, the infrared ranging component can monitor the distance between the mounting plate and the ground, and further obtain the distance between the bottom of the height-setting support frame and the ground. The height-setting support frame can be driven to move up and down by the lifting cylinder to adjust the height of the height-setting support frame, paving the cement stabilized macadam base layer with different thicknesses. The operation is simple and convenient, and it can be applicable to paving devices of different models, improving the flexibility of use. Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0027] Please refer to Figures 1-4 As shown, the present utility model is a height-fixed component for laying a cement stabilized macadam pavement, including a height-fixed support frame 1 and a mounting plate 2. A height-fixed scraping plate 101 is welded and fixed to one side of the height-fixed support frame 1. A rotating motor 102 is clamped and fixed to one end of the height-fixed support frame 1. The mounting plate 2 is arranged on the top of the height-fixed support frame 1, and a lifting cylinder 201 is clamped to the bottom of the mounting plate 2;

[0028] After the mounting plate 2 is installed at the bottom of the laying device, the distance between the mounting plate 2 and the ground is monitored by the infrared ranging assembly 203, and further the distance between the bottom of the height-fixed support frame 1 and the ground is obtained. According to the thickness of the cement stabilized macadam base layer to be laid, the lifting cylinder 201 is controlled to drive the height-fixed support frame 1 to adjust the height, so that the height-fixed support frame 1 fixes the height of the laying material. The laying device is controlled to move and lay the material on the road surface. The height-fixed scraping plate 101 blocks the excessive material laid on the ground by the laying device, and makes the excess material fill the places with insufficient thickness. The excessive scraped material enters the height-fixed support frame 1 for collection as the laying device moves, and the rotating motor 102 drives the rotation of the screw feeding assembly 105 to convey the excess material to a material bucket or other positions, without the need to clean the road surface.

[0029] Among them, as Figures 1-3As shown in the figure, one end of the height-fixed support frame 1 is penetrated and clamped with a metal bellows 103. The metal bellows 103 is located at the other end of the height-fixed support frame 1 relative to the rotating motor 102. A material passing opening 104 is penetrated and opened on one side of the height-fixed support frame 1. The height-fixed scraping plate 101 is located at the center of the bottom of the material passing opening 104. One end of the rotating motor 102 is clamped with a rotating rod 106. A spiral feeding component 105 is welded and fixed on the outer peripheral surface of the rotating rod 106. The rotating rod 106 is penetrated and inserted into one end of the height-fixed support frame 1. The spiral feeding component 105 is located inside the height-fixed support frame 1;

[0030] When the laying device drives the height-fixed component to move, the excess materials laid on the ground by the laying device are blocked by the height-fixed scraping plate 101, and the excess materials are used to fill the places with insufficient thickness. The overflowing materials enter the height-fixed support frame 1 through the material passing opening 104 at both ends and the top of the height-fixed scraping plate 101 for collection. The rotating motor 102 drives the rotating rod 106 and the spiral feeding component 105 to rotate, so that the excess materials are conveyed into the metal bellows 103 and conveyed to other devices through the metal bellows 103, which is convenient for reusing or centrally processing the excess raw materials.

[0031] Among them, as Figure 1 , 4 shown, the bottom of the lifting cylinder 201 is slidably clamped with a telescopic rod 202. The telescopic rod 202 is clamped to the top of the height-fixed support frame 1. Mounting holes 204 are penetrated and opened around the top of the mounting plate 2. An infrared distance measuring component 203 is clamped and fixed on one side of the bottom of the mounting plate 2. The height-fixed scraping plate 101 is located between the height-fixed support frame 1 and the infrared distance measuring component 203;

[0032] The mounting plate 2 is fixed to the bottom of the laying device by bolts penetrating through the mounting holes 204, and the distance between the mounting plate 2 and the ground is monitored by the infrared distance measuring component 203, and further the distance between the bottom of the height-fixed support frame 1 and the ground is obtained. When adjusting the height of the height-fixed component, according to the thickness of the cement stabilized macadam base layer to be laid on the road surface, the lifting cylinder 201 is controlled to drive the telescopic rod 202 to expand and contract, and further the height of the height-fixed support frame 1 is adjusted to control the laying thickness.

[0033] The specific working principle of the utility model is as follows: When it is necessary to lay the road surface, the mounting plate 2 is fixed to the bottom of the laying device by bolts passing through the mounting holes 204, and the distance between the mounting plate 2 and the ground is monitored by the infrared ranging component 203, and further the distance between the bottom of the height-fixing support frame 1 and the ground is obtained. According to the thickness of the cement stabilized macadam base layer to be laid, the lifting cylinder 201 is controlled to drive the telescopic rod 202 to expand and contract, and further the height of the height-fixing support frame 1 is adjusted. The laying device moves and lays the material on the ground. The height-fixing scraper 101 blocks the excessive material laid on the ground by the laying device, and makes the excess material fill the places with insufficient thickness. The overflowing material enters the height-fixing support frame 1 through the material passing ports 104 at both ends and the top of the height-fixing scraper 101 for collection. The rotating motor 102 drives the rotating rod 106 and the screw feeding component 105 to rotate, so that the excess material is conveyed into the metal corrugated pipe 103 and conveyed to other devices through the metal corrugated pipe 103.

[0034] The above are only the preferred embodiments of the utility model, which do not limit the utility model.
