Description

Technical Field

[0001] This invention relates to the field of ground liquid coating construction, and specifically to a liquid leveling construction vehicle device. Background Technology

[0002] When constructing anti-slip pavement, the gel-like liquid needs to be spread on the ground first. Currently, the main method is to manually pour the liquid onto the ground and then manually scrape the liquid onto the ground with a shovel. Using a shovel to scrape the ground is inefficient, and the construction workers need to squat on the ground to scrape the ground, which increases the labor intensity. Summary of the Invention

[0003] In order to overcome the shortcomings of the above technologies, the present invention provides a liquid leveling construction vehicle device that improves construction efficiency and is suitable for construction on different road widths.

[0004] The technical solution adopted by this invention to overcome its technical problems is:

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The present invention will be further described below.

[0039] As attached Figure 1 As shown, a liquid leveling construction vehicle device includes: a chassis 1, with wheels 16 rotatably mounted at its four lower corners; a hopper seat 15, with a hopper 2 mounted on its upper end; a right hanging arm 5, horizontally arranged in the left-right direction, with a plurality of mounting holes I spaced apart in the left-right direction on the right hanging arm 5, through which bolts pass to fix the right hanging arm 5 to the right end of the hopper seat 15; a left hanging arm 9, horizontally arranged in the left-right direction, with a plurality of mounting holes II spaced apart in the left-right direction on the left hanging arm 9, through which bolts pass to fix the left hanging arm 9 to the left end of the hopper seat 15; and N hooks are respectively provided at the front ends of the hopper seat, the right hanging arm 5, and the left hanging arm 9. Plate 6, where N is a positive integer greater than or equal to 2, has a slot 6.1 in the hook plate 6; three leveling devices 7, the first leveling device 7 is inserted into the slot of the hook plate 6 on the hopper seat, the second leveling device 7 is inserted into the slot of the hook plate 6 on the right hanging arm 5 and the right end of the hook plate 6 on the hopper seat 15, and the third leveling device 7 is inserted into the slot of the hook plate 6 on the left hanging arm 9 and the left end of the hook plate 6 on the hopper seat 15; the lower end of the hopper 2 is provided with several discharge ports, each discharge port is connected to a discharge pipe 4, the lower end of the discharge pipe 4 is located above the corresponding leveling device 7, when the chassis 1 moves by the wheels 16, the leveling device 7 scrapes the glue discharged from the discharge pipe 4 onto the ground.

[0040] The number of leveling devices 7 to be used is selected according to the width of the construction road surface. If only one leveling device 7 is used, the leveling device 7 is hooked into the slot 6.1 of the hook plate 6 at the front end of the hopper seat 15 to connect and fix the leveling device 7 to the hopper seat 15. If two leveling devices 7 are used, the bolts on the left hanging arm 9 or the right hanging arm 5 are loosened, the left hanging arm 9 or the right hanging arm 5 is pulled out horizontally in the left and right direction and then tightened with bolts. The second leveling device 7 is hooked into the slot 6.1 of the hook plate 6 on the left hanging arm 9 or the right hanging arm 5. If three leveling devices 7 are used, the bolts on the left hanging arm 9 and the right hanging arm 5 are loosened, the left hanging arm 9 and the right hanging arm 5 are pulled out horizontally in the left and right direction and then tightened with bolts. The leveling device 7 is hooked into the slot 6.1 of the hook plate 6 on the corresponding left hanging arm 9 or the right hanging arm 5. The flexible combination and matching improves the flexibility of construction. The leveling device 7 is connected to the hopper seat 5 and the left hanging arm 9 or right hanging arm 5 by hook, which is convenient for installation and disassembly. The adhesive is added to the hopper 2. Since the adhesive used for construction is viscous, the flow rate is not fast. The adhesive in the hopper 2 is added to the ground in the area of ​​the leveling device 7 through the corresponding discharge port and the discharge pipe 4. The construction operation can be completed without the need for valve control. Then, the driving chassis 1 moves in a straight line using the wheels 16, and the leveling device 7 moves in the back and forth direction to level the liquid on the ground, realizing the liquid leveling and spreading construction, which improves the construction efficiency. Further preferably, the discharge pipe 4 is a flexible hose. Before adding the adhesive to the hopper 2, the discharge end of the hose can be hung with a wire to be higher than the liquid level in the hopper 2. After pouring out the adhesive, the discharge end of the hose is placed in the corresponding area of ​​the leveling device 7.

[0041] If only one scraper device 7 is used, loosen the bolts, move the left hanging arm 9 and the right hanging arm 5 inwards so that they are fully inserted into the hopper seat 15, insert the bolts into the corresponding mounting holes I on the left hanging arm 9 and the corresponding mounting holes II on the right hanging arm 5, and screw them into the hopper seat 15 to achieve the storage and fixation of the left hanging arm 9 and the right hanging arm 5 without occupying horizontal space.

[0042] As attached Figure 4 and attached Figure 5 As shown, in a specific embodiment of the present invention, the leveling device 7 has the following structure, comprising:

[0043] The bracket 14 is composed of two side beams 14.1 respectively located at the left and right ends, and the two side beams 14.1 are parallel to each other;

[0044] Several scraper frames I10 and several scraper frames II11 are arranged at intervals in the left and right direction. A scraper frame II11 is provided between every two adjacent scraper frames I10. The scraper frames I10 are inserted into the bracket 14 through the insertion mechanism, and the scraper frames II3 are inserted into the bracket 14 through the insertion mechanism.

[0045] Scraper I 10.1 is vertically fixed to the front end of scraper I 10. The length of scraper I 10.1 is set along the left and right direction. The lower end face of scraper I 10.1 is parallel to the ground. After scraper I 10 is inserted into bracket 14 through the insertion mechanism, the distance between the lower end face of scraper I 10.1 and the ground is matched with the height of the liquid.

[0046] Scraper II11.1 is vertically fixed to the front end of scraper II11. The length of scraper II11.1 is set along the left and right direction. The lower end face of scraper II11.1 is parallel to the ground. After scraper II11 is inserted into bracket 14 through the insertion mechanism, the distance between the lower end face of scraper II11.1 and the ground is matched with the height of the liquid.

[0047] A pin 14.6 is installed at the rear end of the side beam 14.1. The axis of the pin 14.6 is horizontally set in the left-right direction, and the pin 14.6 is locked in the corresponding slot of the hook plate 6. When spreading adhesive on the road for leveling operations, the scraper I 10 and scraper II 11 are inserted into the bracket 14 through the plug-in mechanism. Due to the plug-in connection, not only is installation and disassembly convenient, but the length in the left-right direction can also be easily adjusted. The adhesive is poured into the bracket 14 and is located on the ground at the rear end of the scraper I 10.1 and scraper II 11.1. Then, the chassis 1 moves, and the entire bracket 14 moves from front to back. Since the height of the scraper I 10.1 and scraper II 11.1 from the ground is the height of the liquid level to be leveled, the lower edge of the scraper I 10.1 and scraper II 11.1 levels the liquid on the ground, realizing the liquid leveling and spreading construction, and improving the construction efficiency.

[0048] In one specific embodiment of the present invention, as shown in the appendix Figure 6 As shown, the scraper I10 consists of a long side plate I10.2 located at the left end and a short side plate I10.3 located at the right end. The long side plate I10.2 and the short side plate I10.3 are parallel to each other. The front ends of the long side plate I10.2 and the short side plate I10.3 are connected and fixed by a connecting plate I10.4. Support plate III10.6 and support plate IV10.7 are vertically arranged below the rear end of the long side plate I10.2. The lower end surfaces of support plate III10.6 and support plate IV10.7 are in contact with the ground. Support plate II10.5 is vertically arranged below the rear end of the short side plate I10.3. The lower end surface of support plate II10.5 is in contact with the ground. (See attached diagram) Figure 7As shown, the scraper II11 is composed of a long side plate II11.2 located at the left end and a short side plate II11.3 located at the right end. The long side plate II11.2 and the short side plate II11.3 are parallel to each other. The front ends of the long side plate II11.2 and the short side plate II11.3 are connected and fixed by a connecting plate II11.4. Support plate VI11.6 and support plate VII11.7 are arranged vertically below the rear end of the long side plate II11.2. The lower end surfaces of support plate VI11.6 and support plate VII11.7 are in contact with the ground. Support plate V11.5 is arranged vertically below the rear end of the short side plate II11.3. The lower end surface of support plate V11.5 is in contact with the ground. Because the liquid has strong fluidity, scrapers I 10.1 and II 11.1 can insert support plates II 10.5, III 10.6, IV 10.7, V 11.5, VI 11.6, and VII 11.7 into the grooves created by the liquid to scrape and fill them.

[0049] In one embodiment of the present invention, the insertion mechanism may have the following structure, including connecting beam I 14.2 and connecting beam II 14.4. The left and right ends of connecting beam I 14.2 are respectively connected and fixed to the front end of side beam 14.1 on the same side. The left and right ends of connecting beam II 14.4 are respectively connected and fixed to the rear end of side beam 14.1 on the same side. A plurality of slots I 14.3 are spaced apart along the left and right direction on connecting beam I 14.2, and a plurality of slots II 14.5 are spaced apart along the left and right direction on connecting beam II 14.4. Each slot I 14.3 and each slot II 14.5 overlaps one-to-one in the front and back direction. The width of slots I 14.3 and slots II 14.5 is consistent with the thickness of long side plate I 10.2, short side plate I 10.3, long side plate II 11.2 and short side plate II 11.3. A stop block 10.8 is provided vertically below the rear end of long side plate I 10.2. I10.2 is inserted into the corresponding slots I14.3 and II14.5; support plate III10.6 is located at the rear end of connecting beam I14.2; support plate IV10.7 is located at the front end of connecting beam II14.4; stop block 10.8 is located at the rear end of connecting beam II14.4; long side plate II11.2 is inserted into the corresponding slots I14.3 and II14.5; support plate VI11.6 is located at the rear end of connecting beam I14.2; support... Support plate VII11.7 is located at the front end of connecting beam II14.4, short side plate I10.3 is inserted into the corresponding slot I14.3, support plate II10.5 is located at the front end of connecting beam I14.2, short side plate II11.3 is inserted into the corresponding slot I14.3, support plate V11.5 is located at the front end of connecting beam I14.2, and the front end faces of scraper II11.1 on both sides are in contact with the rear end faces of the corresponding scraper I10.1 on the same side.Scraper I 10 is inserted into slots I 14.3 and II 14.5 via its side plate I 10.2 and short side plate I 10.3, enabling quick installation and disassembly. Scraper II 11 is inserted into slots I 14.3 and II 14.5 via its long side plate II 11.2 and short side plate II 11.3, also enabling quick installation and disassembly. Because support plates II 10.5 and III 10.6 are located at the rear end of connecting beam I 14.2, support plate IV 10.7 is located at the front end of connecting beam II 14.4, and stop block 10.8 is located at the rear end of connecting beam II 14.4, scraper I 10 achieves locking and securing with bracket 14 in the front-rear direction. Therefore, when the entire leveling device 7 moves back and forth, the scraper I 10 moves back and forth with the bracket 14 and will not come loose. The front end faces of the scraper II 11.1 on both sides of the scraper II 11 are in contact with the rear end faces of the corresponding scraper I 10.1 on the same side. Therefore, the scraper I 10.1 limits the position of the front end of the scraper II 11.1. The support plates V 11.5 and VI 11.6 of the scraper II 11 are located at the rear end of the connecting beam I 14.2, and the support plate VII 11.7 of the scraper II 11 is located at the front end of the connecting beam II 14.4. Therefore, the rear end position of the scraper II 11 is limited, so that the scraper II 11 moves back and forth with the bracket 14.

[0050] As attached Figure 8 As shown, in one embodiment of the present invention, two baffles 8 are further included, one baffle 8 located on the left and the other baffle 8 located on the right. A groove 8.1 is provided below the front end of each baffle 8, and a support plate I 8.2 is provided below its middle portion. The groove 8.1 at the front end of the baffle 8 is inserted into a slot I 14.3 at the left or right end of the connecting beam I 14.2, and the rear end of the baffle 8 is inserted into a slot II 14.5 at the left or right end of the connecting beam II 14.4. The lower end face of the support plate I 8.2 is in contact with the ground. Depending on the position of the slot I 14.3 and slot II 14.5 into which the card is inserted, the inner end face of the two baffles 8 contacts the outer end face of the scraper I 10.4 on the same side. At this time, the baffle 8 can prevent the adhesive from flowing to its outer end, thus effectively controlling the scraping width.

[0051] In one embodiment of the present invention, a handrail 17 is also included, which is vertically disposed at the rear end of the vehicle chassis 1. The handrail 17 facilitates the movement of the entire vehicle chassis 1, further improving ease of use.

[0052] As attached Figure 3 and attached Figure 10As shown, in one embodiment of the present invention, the rear end of the hopper seat 15 is rotatably mounted on the chassis 1 via a rotating shaft 18. The lower end of the electric push rod 5 is hinged to the chassis 1, and the head end of its piston rod is hinged to the hopper seat 15. When the piston rod of the electric push rod 5 extends outward, it pushes the hopper seat 15 to rotate rearward, causing each leveling device 7 to flip upward. After construction is completed, the electric push rod 5 drives the hopper seat 15 to flip, causing each leveling device 7 to flip upward away from the ground, thereby achieving the function of folding and storage, preventing damage to the leveling devices 7 caused by the movement of the chassis 1 during transportation.

[0053] As attached Figure 2 As shown, in one embodiment of the present invention, a fixing plate 12 is further included, which is horizontally arranged in the left-right direction. The inner end of the fixing plate 12 is mounted on the chassis 1, and a pointer 13 is mounted on its outer side. The pointer 13 is arranged in the vertical direction. The pointer 13 points to the ground, which facilitates the chassis 1 to move in a straight line along ground lines or markings such as tape when it is moving, thus improving the convenience of operation.

[0054] As attached Figure 9 As shown, hook plates 6 are respectively provided on the left and right sides of the upper rear end of the hopper seat 15. When only one leveling device 7 is used, the leveling device 7 is hooked into the slot 6.1 of the hook plate 6 at the front end of the hopper seat 15 via the pin 14.6. The other two leveling devices 7 can be placed on the chassis 1 at the rear end of the hopper seat 15, and the other can be hooked into the slot 6.1 of the hook plate 6 at the rear end of the hopper seat 15 via the pin 14.6. The two unused leveling devices 7 are arranged one above the other for easy storage.

[0055] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
