Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular is a marking device for the construction of a hazardous chemical storage room. Background Art

[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that have properties such as toxicity, corrosion, explosion, combustion, and combustion-supporting properties, and are harmful to the human body, facilities, and the environment.

[0003] Due to the dangerous properties of hazardous chemicals themselves, they need to be stored in specific hazardous chemicals warehouses.

[0004] When storing hazardous chemicals, corresponding monitoring, ventilation, sun protection, temperature control, fire prevention, explosion prevention, pressure relief, anti-toxicity, neutralization, moisture prevention, lightning protection, anti-static, corrosion prevention, leakage prevention, protective dikes and other safety facilities should be installed in the warehouse according to the types and characteristics of hazardous chemicals. They should be maintained and maintained in accordance with national standards and relevant regulations to ensure safety requirements. Storage sites should be equipped with ventilation and alarm devices and ensure that they are in normal use under any circumstances. In order to better build hazardous chemical storage rooms according to the planned implementation, a marking device is usually used to draw lime lines for each area on the ground before construction.

[0005] The existing patent authorization announcement number is CN211137122U, and the patent name is an invention patent for a construction marking device. The marking machine is recorded, and the bottom of the marking machine is fixedly connected with a connecting plate, and the inner cavity of the connecting plate is movably connected with a rotating wheel through an axle pin. The present invention allows the marking machine to work by the user. When resting, the user rotates the screw rod, and the screw rod rotates and cooperates with the threaded groove to move the screw rod downward. The screw rod moves downward and drives the fixed plate to move downward. The fixed plate moves downward and drives the connecting column to move downward. The connecting column moves downward and drives the slide plate to move downward. The slide plate moves downward in cooperation with the slide groove to limit the movement while compressing the spring. Then the slide plate moves downward and drives the brake block to contact the rotating wheel and cooperate with the anti-skid pattern to fix the rotating wheel, so that the marking machine will not move. This solves the problem that the existing marking device is inconvenient to use and difficult to park, reduces the labor of the user's operation, reduces the user's processing workload, and improves the practicality of the marking device.

[0006] The marking device described in the above patent adopts a wheelbarrow as the main body, which is pushed by manpower to move during use. During the movement, lime falls to form a lime line. This solution mainly relies on manpower to control the direction during use, which is easy to deviate from the direction. In addition, the length of the marking line needs to be measured during movement, which is troublesome. Especially when turning, the direction needs to be recalibrated, making the entire marking process cumbersome and not meeting people's requirements. In summary, the existing marking devices have certain drawbacks when used and do not meet people's usage requirements. For this reason, we propose a marking device for the construction of hazardous chemicals storage rooms. Summary of the invention

DETAILED DESCRIPTION

[0026] The embodiment of the present application provides a marking device for the construction of a hazardous chemical storage room, thereby solving the problem that the existing marking device in the prior art adopts a wheelbarrow as the main body, and relies on manpower to push the trolley to move during use. During the movement, lime falls to form a lime line. This solution mainly relies on manpower to control the direction during use, which is easy to deviate from the direction. In addition, the length of the marking line needs to be measured during movement, which is quite troublesome. In particular, when turning, the direction needs to be recalibrated, making the entire marking process relatively cumbersome.

[0027] Embodiment 1: A marking device for the construction of a hazardous chemicals storage room, such as Figure 1-10 As shown, it includes an electric trolley 1, an identification and distance measuring device 3, a rotating component 4 and a lime guide cover 5; a storage component 2 for placing lime is installed on the electric trolley 1, in which lime used for marking is stored; the identification and distance measuring device 3 is arranged at the front end of the electric trolley 1, and is used to measure the distance between the electric trolley 1 and the turning point of the marking, so that relevant personnel can understand the length of the marking; the rotating component 4 is installed on the electric trolley 1, and is used to change the movement direction of the electric trolley 1 at the turning point of the marking to avoid the steering angle being incorrect and the occurrence of offset; the lime guide cover 5 is installed on the lower end surface of the electric trolley 1, and the lime guide cover 5 is connected with the storage component 2, and the lime guide cover 5 guides the lime to fall evenly on the ground to form a lime line; wherein, the lime guide cover 5 is provided with an opening adjustment device for adjusting the width of the marking, which can adjust the width of the lime line falling on the ground, thereby achieving a better marking effect.

[0028] The electric trolley 1 is also equipped with a power supply assembly, which supplies power to the entire electric trolley 1 and the electronic devices carried thereon. The electric trolley 1 is provided with a wireless module, which enables wireless control of the electric trolley 1 and the electronic devices carried thereon as well as data interaction.

[0029] When in use, insert a marking post (located directly in front of the electric trolley 1) at the end where marking is required, input the distance where the electric trolley 1 needs to be marked, and then start the electric trolley 1. When the electric trolley 1 moves, the distance measuring device 3 measures the distance to the marking post (when the electric trolley 1 is affected by the road surface and deviates, the measured distance will suddenly change, and people can directly observe at this time. The front wheel angle of the electric trolley 1 can be remotely controlled. A steering motor is installed on the front wheel, which can adjust the movement direction of the electric trolley 1 so that the electric trolley 1 is in the correct direction). When it moves to the set distance, start the rotating component 4 to steer, and continue marking until the entire marking process is completed.

[0030] The present invention records a marking device for the construction of a hazardous chemical storage room, which uses an electric trolley 1 as a carrier, and is combined with an identification and ranging device 3 and a rotating component 4, which can realize linear motion and steering, so that the marking device can realize automatic and accurate marking without manual support from staff, making the marking process relatively simple, and the marking is relatively accurate, with good use effect and good use prospects.

[0031] Embodiment 2: On the basis of Example 1, Figure 1 - Figure 6 As shown, this embodiment also records the following structure: The identification and distance measuring device 3 includes a mounting plate, a laser rangefinder 31 and a road debris removal component for clearing debris from the marked area: the mounting plate is fixedly mounted on the front end face of the electric trolley 1; the laser rangefinder 31 is fixedly mounted on the mounting plate to measure the distance to the identification column; the road debris removal component is arranged at the lower end of the mounting plate to push away debris, so that the marking is clear and easy to identify.

[0032] The road debris removal component includes a lifting component 32 and a push block 33: the main body of the lifting component 32 is fixedly installed in the middle position of the lower end surface of the mounting plate, and the lifting component 32 can change the height of the push block 33 so that the push block 33 is close to the ground, thereby being able to push away the debris on the ground; the push block 33 is fixedly installed at the telescopic end of the lifting component 32; wherein, the push block 33 is inclined at the end surface facing the movement direction of the electric trolley 1, and its front end surface is in a herringbone shape, which is used to push the debris on the lime-marked area to both sides.

[0033] The rotating assembly 4 includes a motor assembly and a support rod 41: the motor assembly is fixedly mounted on the upper end surface of the electric trolley 1, and the motor assembly adopts a motor with a brake structure and a speed change structure, which can achieve a slow adjustment of the angle to avoid over-adjustment; The support rod 41 is installed on the lower end surface of the electric trolley 1 , and the support rod 41 is located directly below the center of gravity of the electric trolley 1 , so the support rod 41 can stably support the electric trolley 1 .

[0034] The support rod 41 includes a sleeve, a lifting column 42 and a limit plate 43: the sleeve is fixedly mounted on the lower end surface of the electric trolley 1; the sleeve plays a protective role, the lifting column 42 is rotatably connected to the inner surface of the sleeve through a bearing, and the main body of the lifting column 42 is rotatably mounted on the lower end surface of the electric trolley 1 through a bearing. When the lifting column 42 is in a retracted state, the limit plate 43 does not contact the ground. When the lifting column 42 is extended, the limit plate 43 contacts the ground, lifts up the electric trolley 1, and cooperates with the rotating component 4 to realize the in-situ turning of the electric trolley 1.

[0035] The main body of the lifting column 42 is fixedly connected to the output end of the motor assembly; the limit plate 43 is installed on the telescopic end of the lifting column 42 by bolts; wherein, several groups of limit columns are fixedly installed on the lower end surface of the limit plate 43, which can be inserted into the soil to increase the stability of the support rod 41. When located on a hard ground, the limit plate 43 with the limit columns can be removed and replaced with an ordinary limit plate 43 with anti-slip patterns on the bottom. It is suitable for different scenarios and has a wide range of applicability.

[0036] An annular first channel 44 and four groups of second channels 45 equidistantly provided and perpendicular to the first channel 44 are provided inside the sleeve. Four groups of limiting protrusions 46 are provided on the outer surface of the telescopic end of the lifting column 42. The limiting protrusions 46 are located inside the second channel 45 or the first channel 44.

[0037] When the lifting column 42 does not rise or fall, the limit protrusion 46 is located inside the second channel 45, and the vehicle cannot turn at this time. When the lifting column 42 rises or falls to the point where the limit protrusion 46 is located at the connection between the first channel 44 and the second channel 45, the electric trolley 1 will be lifted up. At this time, the motor assembly is started, and the electric trolley 1 drives the sleeve to rotate to achieve turning.

[0038] A proximity switch sensor 47 is installed on one group of limit protrusions 46. A metal object that triggers the proximity switch sensor 47 is arranged inside the intersection of the first channel 44 and the second channel 45. The proximity switch sensor 47 is electrically connected to the motor assembly. When the proximity switch sensor 47 passes by the metal object, it will send a signal to the motor assembly, at which time the motor assembly stops running, thereby achieving fixed angle adjustment.

[0039] When in use, the electric trolley 1 moves to the steering position, and the lifting column 42 is started. When the lifting column 42 is extended, the limit plate 43 contacts the ground, and the electric trolley 1 is lifted up. At this time, several groups of limit columns can be inserted into the soil to increase the stability of the support rod 41. The motor assembly is started, and the motor assembly drives the electric trolley 1 to rotate. When it rotates 90°, the proximity switch sensor 47 passes by the metal object and sends a signal to the motor assembly. At this time, the motor assembly stops running to achieve fixed adjustment of the angle.

[0040] The number of the second channels 45 can also be set to be more, such as 8 groups or 16 groups, which can rotate at more angles and have more applicable scenarios. This patent sets it to 4 groups, with relatively low processing accuracy and low cost, and it can fully meet the needs of hazardous chemicals storage room construction.

[0041] The present invention records a marking device for the construction of a hazardous chemical storage room, which records a rotating component 4. When turning, the lifting column 42 extends, driving the limit column on the limit plate 43 to be inserted into the ground, realizing the limit and lifting the electric trolley 1. At this time, the proximity switch sensor 47 cooperates with the motor component to drive the electric trolley 1 to rotate 90°, realizing the precise turning of the electric trolley 1, thereby realizing precise marking. During the marking process, there is no need for manpower to repeatedly measure the distance and calibrate the angle. The marking is relatively convenient, the marking speed is fast, the use effect is good, and it has a good use prospect.

[0042] Embodiment 3: On the basis of Example 2, Figure 6-Figure 10 As shown, this embodiment also records the following structure: The storage assembly 2 includes a storage tank body and a support column 21: the storage tank body is tilted and fixedly installed on the electric trolley 1, and its tilted setting can facilitate the placement of lime; the support column 21 is fixedly installed on the electric trolley 1, and one end of the support column 21 is fixedly installed on the outer surface of the storage tank body; wherein, an installation cavity is opened inside the support column 21 near the upper end, and a vibrating hammer 22 is installed inside the installation cavity. When the vibrating hammer 22 is started, its active end repeatedly strikes the outer surface of the storage tank body, thereby effectively preventing the lime from getting stuck and allowing the lime to fall stably.

[0043] The outer surface of the support column 21 is provided with a heat dissipation hole connected to the installation cavity. The inner side of the heat dissipation hole is higher than the outer side, which can effectively prevent rainwater from entering.

[0044] The opening adjustment device includes two groups of symmetrically arranged adjustment components, which are inserted into the interior of the lime guide cover 5 from the opening at the side end of the lime guide cover 5, and can cover the outlets on both sides of the lime guide cover 5, thereby changing the width of the lime line.

[0045] The adjustment assembly includes a slider 51, a guide block 52, a movable sleeve 53 and a limit block 54: The slider 51 is inserted into the interior of the lime guide cover 5; one end of the guide block 52 is fixedly installed on the slider 51, and the other end of the guide block 52 passes through the strip opening on the lime guide cover 5 and extends to the outside of the lime guide cover 5, so as to facilitate the adjustment of the position of the slider 51 from the outside; the movable sleeve 53 is arranged on the guide column at the other end of the guide block 52 through a spring sleeve, so that the movable sleeve 53 has space to move up and down; the limit block 54 is fixedly installed on the movable sleeve 53; wherein, the outer surface of the lime guide cover 5 is provided with a limit groove 55, and a plurality of groups of slot structures that are engaged with the limit block 54 are evenly spaced on the limit groove 55, and when the slot is engaged with the limit block 54, the position of the slider 51 is limited.

[0046] It is also possible to use a screw, a screw rack and a bearing (similar to the structure of the guide structure height adjustment), but this method is relatively slow to adjust (the number of rotations is relatively large), so it is not used.

[0047] Before use, the movable sleeve 53 (with a handle on the movable sleeve 53) is pulled upward to separate the limit block 54 from the limit groove 55. At this time, the movable sleeve 53 is moved inward or outward to drive the slider 51 to move inward or outward, so that the lime opening becomes larger or smaller.

[0048] The present invention records a marking device for the construction of a hazardous chemical storage room, which records an opening adjustment device. When in use, lime lines of different widths are used when constructing hazardous chemical storage rooms of different standards, so that construction requirements can be clearly understood during subsequent construction, making subsequent construction of hazardous chemical storage rooms more convenient, effectively reducing construction abnormalities, having good use effect, and having good use prospects.

[0049] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
