Description

Technical Field

[0001] This utility model relates to a stone restoration system and belongs to the technical field of stone restoration systems. Background Technology

[0002] Currently, roadside stones or marble removed during road construction, urban construction, or building construction in China are often discarded or broken due to old age, corrosion, or the presence of firmly attached cement and dirt. Stone is a non-renewable resource, and its restoration and reuse is a measure that benefits the country and its people.

[0003] There are two main methods for restoring fixed stone surfaces: flame treatment and chemical cleaning / renovation (for the surface of fixed stone). Flame treatment, used on fixed walls or floors, requires fuel that is flammable and explosive during transportation and construction. Chemical cleaning / renovation uses acid to corrode and restore fixed walls or floors, requiring rinsing with water; the waste liquid is difficult to recycle and poses a certain degree of environmental pollution. Both of these methods are very difficult to completely remove cement residue, oil stains, paint, and other contaminants adhering to marble surfaces.

[0004] Marble is a non-renewable resource, and there is currently no equipment in China for the restoration of kerbstones, paving marble slabs, and architectural marble slabs and blocks that have been removed during construction. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a device for physically cleaning and restoring marble after demolition using high-pressure water jet spraying. It can thoroughly remove cement residue, oil stains, paint and other substances adhering to the marble surface, making it indistinguishable from new marble. It is safe, environmentally friendly and pollution-free, with high restoration efficiency and good results. The cleaning water can be reused after filtration. The cleaning process can be remotely controlled, making it safe and reliable. This enables the reuse of waste marble and reduces the cost of marble resources.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A stone restoration system, characterized in that it includes an automatic conveying and cleaning device, said automatic conveying and cleaning device comprising components configured on a frame:

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] Example 1

[0031] A stone restoration system comprises three main parts: a high-pressure water system, a cleaning control box, and an automatic conveying cleaning system. The high-pressure water system includes a clean water tank, a water pump attached to the clean water tank, and a wastewater sedimentation and filtration tank. Its maximum working pressure is 1000 kg / min, and its flow rate is 50 liters / minute, providing a sufficiently high-pressure water source to the automatic conveying cleaning system. The cleaning control box allows for remote control of the automatic conveying cleaning system from a safe line of sight of 3-5 meters. The control box is connected to the equipment's power distribution box via a waterproof control cable. The automatic conveying cleaning system includes a roller conveying mechanism 1, a positioning and adjustment mechanism 2, a jet cleaning mechanism 3, and a clamping and tilting mechanism 4, all mounted on the equipment frame.

[0032] The following is a detailed description of each part of the automatic conveyor cleaning equipment:

[0033] The roller conveyor mechanism 1 is positioned above the equipment frame to convey marble. Its structure includes several conveyor rollers 11 arranged together, connected by a chain 12, forming a roller conveyor belt above the equipment frame. The power for the conveyor rollers 11 comes from a transmission motor 13. Following the marble's direction of travel, the roller conveyor belt has a loading area, a positioning and adjustment area, a jet cleaning area, a clamping and turning area, and a unloading area. Corresponding sensors are installed on the equipment frame in different functional areas.

[0034] The positioning adjustment mechanism 2 is configured in the positioning adjustment area of ​​the roller conveyor belt and is used for the position correction and adjustment of single or multiple marble pieces of the same specification on the roller conveyor belt. Its structure includes a pair of clamping and retracting arms 21, two sliding rods 22, two positioning blocks 23, and two positioning cylinders 24. The lower ends of the two clamping and retracting arms 21 are slidably sleeved on the two sliding rods 22. The upper ends of the two clamping and retracting arms 21 extend upwards from the middle of the two conveyor rollers 11, and a positioning block 23 is installed at each end. The two positioning cylinders 24 are mounted opposite each other on the equipment frame, and their output ends act on the two clamping and retracting arms 21 respectively. When the positioning sensor on the equipment frame senses that the marble has been conveyed to the positioning adjustment area, the roller conveyor belt stops rotating, and the two positioning cylinders 24 begin to operate, pushing the two clamping and retracting arms 21 to move towards the center along the two sliding rods 22. The two positioning blocks 23 will then press against both sides of the marble and push it to the set position (centered on the roller conveyor belt), completing the positioning adjustment of the marble. The positioning adjustment mechanism 2 then resets.

[0035] The jet cleaning mechanism 3 includes a first cleaning mechanism for cleaning the upper surface and front and rear sides of the marble, and a second cleaning mechanism for cleaning the left and right sides of the marble. When the marble passes through the jet cleaning zone, the two cleaning mechanisms are activated simultaneously to complete the overall cleaning of the marble.

[0036] The first cleaning mechanism includes an electric lifting assembly, a jet angle adjustment assembly, and a jet nozzle 31. The electric lifting assembly is used to adjust the height of the jet nozzle 31 according to the thickness of the marble, and the jet angle adjustment assembly is used to adjust the nozzle angle of the jet nozzle 31 to achieve cleaning of the front and rear sides. A pair of electric lifting assemblies are configured, installed facing each other on both sides of the equipment frame. Each assembly includes a lifting motor 32, a turbine driven by the lifting motor 32, and a worm gear 33 adapted to the turbine. A lifting linkage rod 34 is installed between the turbines of the two electric lifting assemblies to achieve synchronization.

[0037] The jet angle adjustment assembly includes a lead screw 35 and a swing rod 36 arranged parallel to each other. The two ends of the lead screw 35 are mounted on the upper ends of the worm gears 33 of the two electric lifting assemblies through brackets and bearings, and one end of the lead screw 35 is driven and controlled by a rotary motor 37. The upper end of the jet nozzle 31 is movably sleeved on the swing rod 36, and the lower end near the nozzle is slidably mounted on the lead screw 35. The lateral position of the jet nozzle 31 is moved by rotating the lead screw 35. The swing arm 36 is mounted above the lead screw 35 via an adjusting bracket 38. The adjusting bracket 38 has a semi-circular groove 38a for accommodating the end of the swing arm 36, and a manual adjusting rod 39 is connected to the end of the swing arm 36. The manual adjusting rod 39 can pull the end of the swing arm 36 to swing at a certain angle along the semi-circular groove 38a. The manual adjusting rod 39 is provided with pin holes, and the adjusting bracket 38 is provided with several corresponding pin holes. When the swing arm 36 is pulled to a predetermined position by the manual adjusting rod 39, the rotation position of the swing arm 36 can be fixed by a plug-in fixing pin, thereby adjusting the relative position between the swing arm 36 and the lead screw 35, and thus adjusting the tilt angle of the jet nozzle 31 on the lead screw 35. Two positioning sensors are installed on the swing arm 36 to control the lateral movement of the jet nozzle 31.

[0038] The second cleaning mechanism includes an electric lifting assembly 2 and a jet gun head 2 311 mounted on the electric lifting assembly 2. The electric lifting assembly 2 includes a lifting motor 2 321 and a lifting screw 331 controlled by its output. The end of the lifting screw 331 is equipped with the jet gun head 2 311.

[0039] The clamping and flipping mechanism 4 includes a clamping support arm 41 for supporting the marble, a lifting assembly three for lifting the clamping support arm 41, a clamping assembly for fixing the marble, and a flipping assembly for flipping the marble. The lifting assembly three includes an electric lifting side and a manual lifting side connected by a lifting linkage rod, which are installed facing each other on both sides of the equipment frame. The electric lifting side includes a motor and a lifting screw driven by it, and the manual lifting side includes a manual adjustment rocker wheel 49 and a lifting screw driven by it. The two shaft ends of the clamping support arm 41 are respectively arranged on the top of the two lifting screws, so that the clamping support arm 41 is driven to rise and fall by the lifting screws. A pair of clamping assemblies are arranged opposite each other, used to clamp the two sides of the marble. The clamping assemblies on both sides have the same structure, including a support arm 42 fixed to the clamping load-bearing arm 41, and a clamping lever arm 43 mounted above the support arm 42 via a rotating shaft. The inner end of the clamping lever arm 43 is provided with a clamping block 44 for clamping and pressing against the upper surface of the marble. The outer end of the clamping lever arm 43 is provided with a clamping cylinder 45. The cylinder body of the clamping cylinder 45 is fixed to a fixed rod provided on one side of the support arm 42, and the driving end of the clamping cylinder 45 is connected to the outer end of the clamping lever arm 43. A cylinder return spring 46 is also provided on one side of the clamping cylinder 45. The lower end of the cylinder return spring 46 is connected to the fixed rod, and the upper end is connected to the clamping lever arm 43. The clamping load-bearing arm 41 has an internal oil passage communicating with the clamping cylinder 42. One end of the clamping load-bearing arm 41 is connected to an external hydraulic oil pipe via a universal oil inlet 48. The flipping assembly includes a flipping motor 47 connected to one side shaft end of the clamping support arm 41. The flipping motor 47 drives one side shaft end of the clamping support arm 41 to flip the entire clamping support arm 41 and the marble it holds simultaneously.

[0040] Marble restoration and cleaning process:

[0041] 1. Loading: Use a forklift or excavator with hydraulic clamps for loading (the spacing between stones of the same specification is about 15-20 cm).

[0042] 2. When the roller conveyor belt delivers marble from the loading area to the positioning and adjustment area, the roller conveyor belt stops conveying. The positioning and adjustment mechanism adjusts and positions the marble on the roller conveyor belt so that the marble is in the middle position of the roller conveyor belt. After the adjustment is completed, the positioning and adjustment mechanism resets and the roller conveyor belt continues to convey.

[0043] 3. When the roller conveyor belt delivers the adjusted and positioned marble to the jet cleaning area, adjust the distance between the cleaning jet nozzle and the marble cleaning surface, adjust the high-pressure water working pressure to 400~600 kg, and start the first cleaning mechanism and the second cleaning mechanism to jet clean the top surface, front and rear sides and left and right sides of the marble respectively (automatic cleaning is suitable for multiple marbles of the same specification, and manual cleaning is suitable for irregular marbles with greater weight).

[0044] 4. The roller conveyor belt controls the marble to reciprocate. After the first marble reaches the flip position, it stops and the jet gun head is turned off, allowing the high-pressure water to flow back and release pressure; thus completing the cleaning work on the left and right sides, top surface and front and back sides of the marble.

[0045] 5. After the marble reaches the flipping position, the roller conveyor belt stops, the clamping and flipping mechanism clamps and flips the marble, turning the marble over.

[0046] 6. Turn on the jet gun head of the first cleaning mechanism, and the roller conveyor belt will run in reverse to clean the last surface of the marble.

[0047] 7. After cleaning, the marble is conveyed to the unloading area by roller conveyor belt, where it is unloaded, stacked, or loaded onto trucks.

[0048] This invention can thoroughly remove cement residue, oil stains, paint, and other contaminants adhering to the surface of marble. It is safe, environmentally friendly, and pollution-free, with high restoration efficiency and good results. It is safe and reliable, enabling the reuse of waste marble and reducing the cost of marble resources.
