Description

Technical Field

[0001] The invention relates to the technical field of construction marking, in particular to a municipal road and bridge construction marking device. Background Art

[0002] In the construction of municipal roads and bridges, points are marked on the ground (marking stakes or nails) through total stations, GPS and other equipment, and key coordinates such as the axis, side lines, pier positions, etc. of roads and bridges on the design drawings are transferred to the field. The drawing data is converted into operational marks on the field, which directly affects the quality, progress and safety of the project. Ensuring that the construction is carried out according to the design is an indispensable step before construction.

[0003] In road marking, the traditional surveying and laying out marking method usually relies on manual operation, and after the marking powder falls to the ground, the powder is not tightly attached to the ground, and the uncompacted powder will be blown around by wind and other factors, resulting in the inability to retain the marked points for a long time, which is not conducive to the later construction personnel to locate according to the marking position. Therefore, we propose a municipal road and bridge construction marking device. Summary of the invention

[0004] The present invention provides the following technical solution: a municipal road bridge construction dotting device, comprising a dotting box and a storage box fixedly arranged on the upper wall of the dotting box, the dotting box is provided with four universal wheels at the lower end, a quantitative component is provided at the storage box, a connecting block is provided at the inner wall of the upper end of the dotting box, the storage box and the connecting block are connected to each other, a telescopic block is provided below the connecting block, a placement box is provided inside the dotting box, a dust cleaning component is provided at the placement box, and the dust cleaning component and the telescopic block correspond to each other;

[0005] A connecting tube is also fixedly provided on the side wall of the telescopic block, a connecting tube is provided at the lower end of the connecting tube, a limiting ring is arranged around the outer wall of the connecting tube, the limiting ring and the side wall of the fixing plate are fixedly connected by a fixing block, a first tooth plate is fixedly provided on the outer wall of the connecting tube, a second tooth plate is fixedly provided on the inner wall of the connecting tube, a gear is meshed between the first tooth plate and the second tooth plate, a cross bar is fixedly passed through the axis of the gear, both ends of the cross bar are fixed to the limiting ring, a connecting groove is provided on the side wall of the connecting tube, the connecting groove and the cross bar correspond to each other, a pressing plate is fixedly provided on the lower end of the connecting tube, and a through hole corresponding to the connecting tube is provided on the pressing plate.

[0006] Preferably, the quantitative component comprises a feed opening arranged between the storage box and the connecting block, a baffle is correspondingly arranged on the upper wall of the feed opening, the lower wall of the baffle slides on the bottom wall of the storage box, and the upper end of the baffle is arranged on the surface of the storage box.

[0007] Preferably, the four universal wheels are arranged at the four corners of the lower end of the dotting box, and a handle is fixedly connected to the side wall of the upper end of the dotting box.

[0008] Preferably, three fixed plates are arranged in parallel and transversely inside the lower part of the dotting box, and there is a corresponding fixed plate below the telescopic block, the placement box is fixedly arranged on the fixed plate, and rollers are arranged on the lower end side walls of the other two fixed plates.

[0009] Preferably, the dust cleaning assembly comprises an air bag fixed in the placement box, the lower end of the telescopic block and the upper wall of the air bag are in contact with each other, and an air outlet is connected below the air bag.

[0010] Preferably: a threaded cavity is fixedly provided on one side of the placement box, the threaded cavity is fixed on a fixed plate, a matching threaded rod is provided in the threaded cavity, a scraper is fixedly provided at the lower end of the threaded rod, and the upper end of the threaded rod is fixed to each other through an L-shaped push rod and a side wall of the telescopic block.

[0011] Preferably, lubricating oil is applied between the threaded rod and the threaded cavity, and the threaded rod and the scraper are integrally formed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The municipal road and bridge construction dotting device moves upward through the connecting tube, and the crossbar slides in the connecting groove. The connecting groove effectively limits it. When the telescopic block moves upward after dotting, the connecting tube moves downward, and the pressure plate set at the bottom of the connecting tube compacts the powder on the ground after dotting, which effectively enhances the durability of the dotting mark and improves the clarity of the marking point, making the powder fit more closely to the ground and preventing the uncompacted powder from flying around due to wind and other factors, effectively improving the durability of the dotting point, facilitating the later construction personnel to measure and locate in the chassis, and improving the work efficiency of the equipment.

[0014] 2. The municipal road and bridge construction marking device, after the shrinking block squeezes the airbag, the gas is ejected through the air outlet. The gas sprayed in the air outlet can blow away the dust on the ground where the marking is required. At this time, when the telescopic block drops, the L-shaped push rod set on the side wall of the telescopic block drops accordingly. The L-shaped push rod pushes the front threaded rod to rotate and drop, and the scraper fixed at the bottom of the threaded rod cleans the blown dust, effectively ensuring that the marking head can fully contact the ground during marking, avoiding unclear marking or deviation due to obstruction caused by dust. The setting of the cleaning component effectively ensures the marking quality and effectively improves work efficiency

[0015] 3. The municipal road and bridge construction dotting device also pushes the dotting box to move to the construction road that needs to be dotted, and then moves the baffle to control the amount of dotting powder discharged into the connecting pipe through the discharge port, which effectively improves the dotting accuracy, evenly controls the powder discharge amount, ensures the uniform size of the dots, saves materials and reduces costs.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-10 A municipal road and bridge construction marking device comprises a marking box 1 and a storage box 2 fixedly arranged on the upper wall of the marking box 1, four universal wheels 26 are arranged at the lower end of the marking box 1, a quantitative component is arranged at the storage box 2, a connecting block 3 is arranged at the inner wall of the upper end of the marking box 1, the storage box 2 and the connecting block 3 are connected to each other, a telescopic block 4 is arranged below the connecting block 3, a placing box 7 is arranged inside the marking box 1, a dust cleaning component is arranged at the placing box 7, and the dust cleaning component and the telescopic block 4 correspond to each other;

[0029] A connecting pipe 8 is also fixed to the side wall of the telescopic block 4, a connecting tube 9 is provided at the lower end of the connecting tube 8, a limiting ring 13 is arranged around the outer wall of the connecting tube 9, the limiting ring 13 and the side wall of the fixing plate 21 are fixedly connected by a fixing block 10, a first tooth plate 14 is fixed to the outer wall of the connecting tube 8, a second tooth plate 18 is fixed to the inner wall of the connecting tube 9, a gear 17 is meshed between the first tooth plate 14 and the second tooth plate 18, a cross bar 16 is fixed through the axis of the gear 17, both ends of the cross bar 16 are fixed to the limiting ring 13, a connecting groove is provided on the side wall of the connecting tube 9, and the connecting groove and the cross bar 16 correspond to each other, a pressing plate 15 is fixed to the lower end of the connecting tube 9, and a through hole corresponding to the connecting pipe 8 is provided at the pressing plate 15.

[0030] It should be noted that when the connecting tube 9 moves upward, the cross bar 16 slides in the connecting groove, and the connecting groove effectively limits it. When the telescopic block 4 moves upward after the dotting is completed, the connecting tube 9 moves downward, and the pressure plate 15 arranged at the bottom of the connecting tube 9 compacts the powder on the ground after the dotting, which effectively enhances the durability of the dot mark and improves the clarity of the marking point, so that the powder fits more closely to the ground and prevents the uncompacted powder from flying around due to wind blowing and other factors.

[0031] In an optional embodiment, the quantitative component includes a feed opening 25 disposed between the storage box 2 and the connecting block 3, and a baffle 24 is correspondingly disposed on the upper wall of the feed opening 25, and the lower wall of the baffle 24 slides on the bottom wall of the storage box 2, and the upper end of the baffle 24 is disposed on the surface of the storage box 2.

[0032] It should be noted that the baffle 24 is moved to control the amount of dotting powder discharged into the connecting pipe 8 through the discharge port 25, which effectively improves the dotting accuracy, evenly controls the powder discharge amount, ensures the uniform size of the dots, saves materials and reduces costs.

[0033] In an optional embodiment: four μ-direction wheels 26 are provided at the four corners of the lower end of the dotting box 1 , and a handle 12 is also fixedly connected to the side wall of the upper end of the dotting box 1 .

[0034] It should be noted that when dotting is required, the handle 12 is held and the dotting box 1 is pushed to dot along the designated road, thereby increasing the flexibility of the device.

[0035] In an optional embodiment: three fixed plates 21 are horizontally and parallelly arranged inside the lower part of the dotting box 1, and there is a corresponding fixed plate 21 below the telescopic block 4, and the placement box 7 is fixedly arranged on the fixed plate 21, and rollers 11 are rollingly arranged on the lower end side walls of the other two fixed plates 21.

[0036] It should be noted that after the dotting is completed, the dotting box 1 is pushed forward continuously. At this time, the roller 11 arranged at the bottom of the fixed plate 21 assists the second tooth plate 18 to perform secondary rolling on the powder when passing through the dotting area, which effectively improves the durability of the dotting area and facilitates the later construction personnel to perform measurement, positioning and other operations in the chassis, thereby improving the working efficiency of the equipment.

[0037] In an optional embodiment: the dust cleaning assembly includes an air bag 22 fixed in the placement box 7, the lower end of the telescopic block 4 and the upper wall of the air bag 22 are in contact with each other, and an air outlet 23 is connected below the air bag 22.

[0038] It should be noted that when the telescopic block 4 descends, since an air bag 22 is correspondingly provided at the bottom of the telescopic block 4, the telescopic block 4 squeezes the air bag 22 and the gas is ejected through the air outlet 23. The gas sprayed in the air outlet 23 can blow away the dust on the ground where the marking is required, effectively ensuring that the marking head can fully contact the bottom surface during marking.

[0039] In an optional embodiment: a threaded cavity 6 is fixedly provided on one side of the placement box 7, the threaded cavity 6 is fixed on a fixed plate 21, a matching threaded rod 19 is provided in the threaded cavity 6, a scraper 20 is fixedly provided at the lower end of the threaded rod 19, and the upper end of the threaded rod 19 is fixed to each other through an L-shaped push rod 5 and the side wall of the telescopic block 4.

[0040] It should be noted that the L-shaped push rod 5 pushes the threaded rod 19 at the front end to rotate and descend, and the scraper 20 fixed at the bottom of the threaded rod 19 cleans the blown dust, effectively ensuring that the dotting head can fully contact the ground during dotting, avoiding unclear dotting or deviation due to obstruction caused by dust. The setting of the cleaning component effectively ensures the dotting quality and effectively improves work efficiency.

[0041] In an optional embodiment: lubricating oil is applied between the threaded rod 19 and the threaded cavity 6, and the threaded rod 19 and the scraper 20 are integrally formed.

[0042] It should be noted that the jamming caused by the threaded connection when the threaded rod 19 rotates and descends is effectively avoided.

[0043] Working principle: after pushing the dotting box 1 to move to the construction road where dotting is required, the baffle plate 24 is toggled to control the amount of dotting powder discharged into the connecting pipe 8 through the discharge port 25, which effectively improves the dotting accuracy, evenly controls the powder discharge amount, ensures the uniform size of the dotting, saves materials and reduces costs. When the telescopic block 4 is lowered, since the bottom of the telescopic block 4 is provided with an air bag 22, the telescopic block 4 squeezes the air bag 22 and the gas is ejected through the air outlet 23. The gas sprayed in the air outlet 23 can blow away the dust on the ground where dotting is required. At this time, when the telescopic block 4 is lowered, the L-shaped push rod 5 arranged on the side wall of the telescopic block 4 will fall accordingly, and the L-shaped push rod 5 will push the threaded rod 19 at the front end to rotate and fall, and the scraper 20 fixed at the bottom of the threaded rod 19 will clean the blown away dust, effectively ensuring that the dotting head can fully contact with the ground during dotting, avoiding unclear dotting or deviation due to obstruction caused by dust. The setting of the cleaning component effectively ensures the dotting quality and effectively improves work efficiency.

[0044] When the powder enters the connecting tube 8 through the telescopic block 4, since the first tooth plate 14 and the second tooth plate 18 on the inner wall of the connecting tube 9 are meshed with the cross bar 16, when the telescopic block 4 descends to mark, the second tooth plate 18 drives the connecting tube 9 to move upward. Since the rotating shaft of the cross bar 16 passes through the connecting groove on the side wall of the connecting tube 9 and is fixed with the limiting ring 13, when the connecting tube 9 moves upward, the cross bar 16 slides in the connecting groove, and the connecting groove effectively limits it. When the telescopic block 4 moves upward after marking, the connecting tube 9 moves downward, and the pressing plate 15 arranged at the bottom of the connecting tube 9 compacts the powder on the ground after marking, which effectively enhances the durability of the marking and improves the clarity of the marking point, so that the powder fits more closely to the ground, and prevents the uncompacted powder from floating around due to factors such as wind blowing;

[0045] After the dotting is completed, the dotting box 1 is pushed forward again. At this time, the roller 11 set at the bottom of the fixed plate 21 assists the second tooth plate 18 to perform secondary rolling on the powder when passing through the dotting area, which effectively improves the durability of the dotting area and facilitates the later construction personnel to perform measurement, positioning and other operations in the chassis, thereby improving the work efficiency of the equipment.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
