Description

Technical field:

[0001] The invention relates to a paving device, in particular to a paving device for decorative stones and luminous stones for landscape use for permeable concrete. Background technology:

[0002] At present, my country has carried out sponge city construction in more than 30 cities. In the construction of sponge cities, the paving of permeable pavement is a crucial part of the construction of sponge cities.

[0003] With the increasing maturity of permeable pavement paving technology, the design and construction of permeable pavement are indispensable for most urban construction in my country. However, the permeable concrete pavement has a single color and a low degree of mechanization, especially the pavement decoration, which is still mainly based on changing the color of permeable concrete by formwork casting or hand-painting on the surface of permeable concrete.

[0004] One of the problems is that changing the surface layer of permeable concrete for decoration requires changing the color of permeable concrete. The common method of changing color is to add different pigments to the mixer, which requires a certain amount of mixing. At the same time, the added pigments are difficult to clean in the mixer. This increases the difficulty of cleaning and causes adverse effects such as slowing down the construction progress. The second problem is that the surface layer of hand-painted permeable pavement has high requirements for construction personnel. As for the pavement construction effect, the pattern with clear ruler can better meet the requirements of the appearance decoration effect of permeable pavement. Luminous stone is a kind of stone used for decoration in road paving. At present, the laying of luminous stone in road paving is mainly based on manual placement. It takes a long time to place in the construction of permeable concrete, which is difficult, time-consuming and laborious. This requires the development of construction machinery with appearance decorative paving effect to meet the growing requirements of people for the decorative and ornamental effect of paving in the process of paving permeable pavement in large quantities today. Summary of the invention:

[0005] In order to solve the technical problems mentioned in the background technology, the present invention provides a permeable concrete decorative stone paving machine, which can lay out arc-shaped permeable concrete surface decorative patterns with different radii, and has the advantages of convenient and rapid construction, accurate pattern drawing, etc., which are superior to traditional manual paving.

[0006] The technical solution of the present invention is: the permeable concrete decorative stone paver comprises an upper vehicle body enclosure plate 20 and a lower vehicle body, and its uniqueness lies in:

[0007] The stone paving machine also includes a discharge barrel 1, a smoothing trough 3, a launching device, a first motor 9, a vehicle body central axis 14, a lower conical fixture 11, a worm gear 18, a worm 17, a second motor 12, a frequency converter 13, a bottom vehicle support plate 24 and an upper vehicle body turntable 26;

[0008] The inside of the discharge barrel 1 is divided into two layers by a single-hole partition 21 connected to a spiral track; a single-hole baffle 2 is placed below the discharge port of the discharge barrel 1, and the opening of the single-hole baffle 2 corresponds to the upper stone inlet of the smooth groove 3; the lower stone outlet of the smooth groove 3 is located in the gap between the two plastic rotating wheels 5 in the launching device; the upper end of the vehicle body central axis 14 is fixed at the center of the discharge barrel 1;

[0009] The launching device comprises two plastic rotating wheels 5 driven to rotate by the first motor 9, a launching tube 8 and a launching tube bracket 7, the two first motors 9 provide rotating drives of the same size and opposite directions; the angle between the plastic rotating wheel 5 and the horizontal plane is 30°, so as to promote the decorative stone 4 to enter the launching tube 8 through friction; the launching tube 8 is fixed to the upper vehicle body enclosure plate 20 through the launching tube bracket 7; the two first motors 9 and the plastic rotating wheel 5 are fixedly connected with the launching tube bracket 7 and the upper vehicle body enclosure plate 20 through the rotating wheel connecting frame 6, so as to realize that the launching device and the upper vehicle body enclosure plate 20 can rotate together under the drive of the vehicle body central axis 14;

[0010] The lower vehicle body is separated from the upper vehicle body enclosure plate 20, and the lower vehicle body includes a 4-wheel trolley, a bottom vehicle lower bracket 22 and a bottom vehicle support plate 24; the bottom vehicle lower bracket 22 is fixed on the 4-wheel trolley, and the bottom vehicle support plate 24 is fixed via four bottom vehicle lower brackets 22;

[0011] The upper vehicle body turntable 26 is fixedly connected to the single-hole baffle plate 2 via four upper vehicle body brackets 25. A rotating track is provided between the upper vehicle body turntable 26 and the bottom vehicle support plate 24, so that the upper vehicle body turntable 26 can rotate on the bottom vehicle support plate 24 driven by the vehicle body central axis 14.

[0012] The lower conical fixture 11, the worm wheel 18, the worm 17, the second motor 12 and the frequency converter 13 are fixed in the 4-wheel trolley of the lower vehicle body; the lower end of the vehicle body central axis 14 is connected to the upper end of the worm wheel 18 by a thread, and the lower conical fixture 11 is fixed to the lower end of the worm wheel 18 and can be rotated up and down to adjust the height; the worm 17 is driven by the second motor 12, and the second motor 12 is controlled by the frequency converter 13, so that the rotation of the worm 17 drives the rotation of the worm wheel 18, and drives the upper vehicle body enclosure plate and the launching device to rotate together with the discharge barrel 1.

[0013] Preferably, the single-hole partition plate 21 and the single-hole baffle plate 2 can be replaced with replacement parts with different hole diameters according to the size of the stone.

[0014] The present invention has the following beneficial effects:

[0015] First of all, this permeable concrete decorative stone paving machine is innovative in its structural configuration, enriches the content of permeable concrete decorative construction machinery and tools, and has innovative significance.

[0016] Secondly, the permeable concrete decorative stone paving machine has the advantage of mechanized stone paving, that is, the launching distance of decorative stones is controlled by the motor speed and the size of the launching tube, which makes the overall pattern of the upper decorative stone more accurate and meets the aesthetic requirements of the overall effect of the permeable pavement.

[0017] Thirdly, the launch device is composed of two cylindrical plastic soft rubber materials with a radius of 30mm. Driven by the motor, the two rotate in opposite directions and shoot out the decorative stones on the smooth groove through friction. Through the research and development of various materials such as metal, stone, rubber, etc., the cylindrical plastic soft rubber material is selected to make the launch of decorative stones such as luminous stones more powerful and accurate.

[0018] Then, the conical fixture at the lower end of the stone paver can be positioned and rotated downward so that the machine is fixed in the permeable concrete surface layer just poured below, thereby ensuring corresponding stability during the rotation and laying of decorative stones.

[0019] Finally, an auxiliary foot unit is used, which can drive the 4-wheel trolley with a motor to change the position of the permeable pavement decoration. It can also be pushed or set up on the track at the construction site to move the paving equipment. The 4 bottom wheels can be connected to the additional steel track to make the paver walking mechanism walk smoothly.

[0020] In summary, the novel permeable concrete decorative stone laying device proposed in the present invention adopts a novel machine laying mechanism, and has been prepared in the laboratory and optimized with tools, with good results. At present, there are no reports on such decorative stone laying devices for permeable concrete. The present invention innovatively designs a decorative gravel launching device in the decorative link mechanism of permeable concrete construction, providing new ideas for researchers in this field.

[0021] In the past, permeable concrete decoration construction relied on large-scale casting with molds, or hand-painting on the surface of the permeable pavement, which was complicated to construct and had high labor costs. The present invention has a simple structure, saves costs, and can realize the drawing of sufficiently diverse pavement annular patterns. Description of the drawings:

Specific implementation method:

[0029] Luminous stone is a kind of stone used for decoration in road paving. At present, the laying of luminous stone in road paving is mainly done manually. It takes a long time to place it in permeable concrete construction, which is difficult, time-consuming and labor-intensive. There is no automatic device to lay luminous stone in road paving in order to achieve a simple and efficient decorative effect.

[0030] During the construction of permeable concrete, the construction sequence is:

[0031] Gravel is a commonly used material for permeable road paving. The gravel cushion is used to improve the bearing capacity of the shallow layer of the foundation below the bottom surface, and also plays a role in drainage. Its construction operation is mainly manual, and for permeable pavement, the most common is permeable concrete mixed with gravel. Its main construction methods are mixing method, grouting method, and layer paving method. All construction procedures require manual paving of gravel.

[0032] After the permeable concrete pavement surface layer is poured, it should be constructed immediately before the initial setting, using the decorative layer proposed by the present invention to lay decorative stones such as luminous stones on the upper surface of the surface layer. After paving, use a low-frequency flat plate vibrator to lightly vibrate and roll.

[0033] Cover with plastic sheet for curing, sprinkle water after 1 day, and cure for at least 7 days. Finally, apply permeable concrete topcoat.

[0034] Compared with other construction materials, permeable concrete pavement has large pores, which can absorb vehicle noise. Combined with rich and beautiful decorative effect pavement, it can create a quiet and comfortable pavement environment. Permeable pavement can prevent water accumulation after rain, ice and slip after snow, avoid road surface water accumulation, prevent road surface reflection at night, and ensure the safety of vehicles and pedestrians. Rain and snow precipitation are used to increase the relative humidity of the surface, replenish the increasingly depleted groundwater resources in urban areas, give play to the "water reservoir" function of permeable roadbed, improve the living conditions of urban surface plants and soil microorganisms, and adjust the ecological balance. A large number of voids can absorb urban pollutants, reduce dust pollution, and regulate the temperature and humidity of urban space, improve urban thermal circulation, alleviate the heat island effect, and at the same time increase the permeable and breathable area of ​​the city.

[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] like Figure 1 As shown in FIG. 1 , the upper part of the machine body of this decorative stone paving machine is a discharge barrel 1. The detailed diagram of the discharge barrel is as follows: Figure 2 As shown, the barrel is divided into two layers by a single-hole partition 21 connected to a spiral track. The baffle can be replaced according to the hole, which is convenient for the decorative stone to fall in the track. Below the discharge barrel is a single-hole baffle 2, which can be replaced with different hole diameters. The decorative stone 4 falls into the smooth groove 3 in turn.

[0037] The detailed diagram of the launch device is as follows Figure 3 As shown, a plastic rotating wheel 5 is provided on each side of the bottom of the smooth groove, and the two plastic rotating wheels are connected to motors 9 respectively. The motors on both sides provide rotational drives of the same size and opposite directions, and the angle between the rotating wheel and the horizontal plane is 30°, so that the decorative stone enters the launch tube 8 through friction. The motors and the rotating wheels on both sides are connected to the upper vehicle body maintenance plate 20 through the rotating wheel connecting frame 6 and the launch tube bracket 7, and rotate together with them around the main axis. The launch tube 8 is fixed on the upper vehicle body maintenance plate 20 via the launch tube bracket 7.

[0038] Lower body Figure 4 The lower vehicle body is separated from the upper vehicle frame. The lower vehicle body is a 4-wheeled trolley, and the upper vehicle body is supported by the lower vehicle support 22 and the lower vehicle support plate 24. The lower vehicle support 22 is fixed to the lower vehicle body structure. The trolley can be pushed or fixed on the cast-in-place permeable concrete pavement.

[0039] The central axis 14 of the vehicle body connects the upper discharge barrel 1 and the lower conical fixture 11, and a worm gear 18 is provided below the central axis 14 of the vehicle body. The lower vehicle body is connected and fixed with a worm 17, which is driven by a motor 12 and controlled by a frequency converter 13. The rotation of the worm 17 drives the rotation of the worm gear 18, and drives the upper vehicle body maintenance and launching mechanism to rotate together with the discharge barrel 1. At the same time, the speed of the worm 17 is controlled by the frequency converter to drive the central axis 14 and the upper vehicle body. Finally, the trajectory of the decorative stone launch can be adjusted, and the annular decorative stone is launched on the surface layer of the permeable concrete pavement.

[0040] See the upper and lower car body connection details Figure 5 In order to ensure the stability of the upper and lower vehicle bodies, the bottom vehicle support plate 24 is fixed to the bottom vehicle via four bottom vehicle lower brackets 22. The upper vehicle body turntable 26 is fixed to the single-hole baffle 2 at the bottom of the discharge barrel via four upper vehicle body brackets 25. A track is provided between the upper vehicle body turntable 26 and the bottom vehicle support plate 24, so that the upper vehicle body turntable 26 can rotate on the bottom vehicle support plate 24 together with the rotation of the central axis to ensure the stability of the vehicle body rotation. There are four brackets below the discharge barrel, which are fixed on the upper turntable, and the lower turntable has four brackets fixed on the lower vehicle body structure. The upper turntable rotates with the discharge barrel and the central axis together with the upper vehicle body, and the lower turntable does not move. There is a rotating groove between the upper and lower turntables to ensure the free rotation of the upper turntable. The above process needs to be completed before the permeable concrete begins to set, and needs to cooperate with the next step of vibration, compaction and other construction procedures of the permeable concrete surface layer.

[0041] In specific applications, since the end of the smooth groove is connected to the launch device, two motors are set on both sides of the launch device, and two plastic soft rubber cylinders rotate in opposite directions to eject decorative stones by friction. Through the lower body motor inverter, the central axis speed can be remotely controlled to present the pavement of circular decorative stones of different diameters.

[0042] Since the discharge barrel is a double-layer structure, a single-hole partition with an adjustable aperture is provided at the bottom of the upper barrel, and the discharge barrel rotates with the motor, which is convenient for adjusting the discharge amount, avoiding the material from gushing out and accumulating on the smooth groove at one time, and helping the decorative stones to fall in an orderly manner. The spiral track under the single-hole partition is provided with a protective wall to ensure that the decorative stones slide through the bottom baffle in sequence. There is a baffle opening at the interface between the baffle and the smooth groove, and the baffle opening can be adjusted in size to be consistent with the aperture of the single-hole baffle.

[0043] The launch distance of the launch device can be controlled by changing the length of the launch tube. Ultimately, the launch distance of the device can be adjusted within the range of 0 to 1 meter.

[0044] The height can be adjusted by rotating the conical fixture up and down. The fixture goes deep into the permeable concrete before initial setting below the surface layer to find the appropriate height for the vehicle body.

[0045] The present invention can eject decorative stones such as luminous stones onto the surface layer of a newly poured and paved permeable concrete pavement. The structure is firm and easy to move, which is convenient for carrying and construction. The stone ejection can be single shot, and the ejection distance can be achieved by remote control of the frequency converter. Luminous stones of different sizes can be ejected, and the ejection port can be rotated so that the stones rotate 360° to form permeable pavements with different visual effects, such as creating a sense of déjà vu at night (starry sky). Existing permeable concrete decoration technology still relies on manual labor, mainly supporting templates for color casting or manual drawing on the outermost layer of the permeable pavement. The present stone ejection paving decoration machine is easy to move, which is convenient for carrying and using outside, and can control the amount of paving. The decoration is a permeable pavement decorative pattern such as a ring and a starry sky, which is suitable for use in large and small permeable pavements and permeable squares with decorative requirements, with accurate drawing and cost saving.

[0046] The transmission efficiency of the rotary launching mechanism is higher and the energy loss is lower. Compared with the decoration construction schemes such as hand-spreading stone, hand-painting or cast-in-place, it has better aesthetic effect and better pattern accuracy, and has high practical application value.

[0047] The permeable concrete decorative paving device proposed by the present invention, as described above, is only used to introduce the technical solution of the present application in detail, and is only used to help understand the method and core idea of ​​the present invention, and should not be understood as a limitation of the present invention. Any changes or substitutions that can be easily thought of by technicians in this technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
