Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a building construction marker. Background Art

[0002] Construction markers are commonly used tools on construction sites. They are mainly used to mark on the surface of a building or on the ground to facilitate the next step of construction workers. Through fast and accurate marking, they reduce the time construction workers spend searching for and confirming construction locations.

[0003] A construction marker disclosed in announcement number CN217680651 U includes a liquid storage box, a liquid storage chamber is arranged inside the liquid storage box, and the liquid storage chamber is provided with a plurality of liquid storage chambers. A marking mechanism connected to the liquid storage chamber is arranged on the outside of the liquid storage box, and the marking mechanism is provided with a plurality of marking mechanisms and is distributed in a ring shape. When marking in the utility model, different marking patterns are arranged on the plurality of marking mechanisms, and the corresponding blocking bolts can be screwed on the patterns to be marked to open the connecting channel between the marking mechanism and the liquid storage chamber. Marking liquid is stored in the liquid storage chamber. The liquid storage box is tilted by a connecting rod so that the marking liquid in the liquid storage chamber flows into the marking mechanism to infiltrate the marking pattern, so that marking work can be conveniently performed. It can be used to mark different patterns and effectively improve work efficiency.

[0004] In the prior art, a worker holds a handle and then uses a marking sponge on a marking mechanism to mark a construction site. However, it is found during use that the marking is not limited to the ground, but may also be marked on walls or columns. For example, when marking is required at a high place on a wall or column, the worker is required to stand on a ladder to mark during the marking process. Since the marking mechanism contains marking liquid, it is heavy, which will make the worker feel tired after marking for a long time. In addition, when marking for a long time on a lower ground, the worker is required to bend over for a long time to mark, which undoubtedly increases the labor burden of the worker, and the increased fatigue also reduces work efficiency.

[0033] 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.

[0034] See also Figure 1-Figure 5 As shown, the present application provides a construction marker, including a marker body 1, and also including:

[0035] A clamping assembly 2, arranged on one side of the marker body 1, for clamping a wall and a column;

[0036] A lower marking plate 3, arranged below the marker body 1, for ground marking;

[0037] The upper marking component 5 is arranged on the top of the marker body 1 and is used to cooperate with the clamping component 2 to mark the high place;

[0038] A moving component 4, arranged below the marker body 1, and used for moving the marker body 1;

[0039] A driving assembly 6, arranged on one side of the marker body 1, for driving the clamping assembly 2 and the lower marking plate 3;

[0040] During work, in the prior art, the worker holds a handle and then uses the marking sponge on the marking mechanism to mark the construction site. However, it is found during use that the marking is not limited to the ground, but may also be marked on the wall or column. For example, when it is necessary to mark at a high place on the wall or column, the worker needs to stand on a ladder to mark during the marking process. Since the marking mechanism contains marking liquid, it is heavy, which will make the worker feel tired after marking for a long time. Moreover, when marking for a long time on a lower ground, the worker needs to bend over for a long time to mark, which undoubtedly increases the labor burden of the worker, and the fatigue increases and reduces the work efficiency. In order to prevent such incidents from happening, firstly, a marking sponge is added to the marker body 1. Mark the liquid, and then use the moving component 4 to control the marker body 1 to move to the position where it needs to be marked. After the movement is completed, if the ground needs to be marked, the lower marking plate 3 is driven to descend to mark the ground. If a high place needs to be marked, the clamping component 2 is driven to clamp the column or wall. After clamping and fixing, the clamping component 2 is used to drive the marker body 1 to rise, so that the upper marking component 5 is close to the marked place for marking, and the clamping component 2 can be adjusted. Through the setting of the clamping component 2, walls and columns of different thicknesses can be clamped, and then the marked place is marked through the setting of the upper marking component 5. And through the setting of the marker body 1, it can replace manual marking, and through the setting of the lower marking plate 3, the marking of the ground can be convenient, and manual bending over for marking can be avoided, which reduces the labor burden of the staff.

[0041] like Figure 3 and Figure 4 As shown, the clamping assembly 2 includes a clamping box 23; the inner side wall of the marker body 1 is fixedly connected to a partition 14; the side wall of the partition 14 is rotatably connected to a drive shaft 21; the end of the drive shaft 21 away from the partition 14 is fixedly connected to a crown gear 22; the side wall of the marker body 1 above the crown gear 22 is fixedly connected to a connecting plate 24; the clamping box 23 is fixedly connected to the side wall of the connecting plate 24; the end of the clamping box 23 away from the connecting plate 24 is fixedly connected to the side wall of the marker body 1 The side wall of the connecting plate 24 is rotatably connected with a clamping screw 25; the clamping screw 25 is arranged inside the clamping box 23; the clamping screw 25 is provided with two groups; the clamping screw 25 is fixedly connected with a transmission gear 26; the transmission gear 26 is meshed and connected with the crown gear 22; the clamping screw 25 is threadedly connected with a moving plate 27; the end of the moving plate 27 away from the clamping screw 25 is fixedly connected with a clamping block 28; the clamping block 28 is rotatably connected with a roller 29;

[0042] During operation, when marking at a high place, first use the moving component 4 to move the marker body 1 to the wall or column, then move the two groups of clamping blocks 28 to both sides of the wall or column, and drive the crown gear 22 to rotate after reaching the position. When rotating, the crown gear 22 drives the transmission gear 26 to rotate, and the transmission gear 26 drives the clamping screw 25 to rotate. When the clamping screw 25 rotates, it drives the two groups of moving plates 27 to move, and then drives the clamping block 28 to approach the wall and clamp it. A roller 29 is set in the clamping block 28, and the roller 29 is driven by a motor set inside the clamping block 28. After clamping, the roller 29 is driven to rotate, and when it rotates, it drives the marker body 1 to crawl to a higher place. When crawling to the vicinity of the marking place, the upper marking component 5 on the marker body 1 is used for marking. The roller 29 is made of rubber, which can play an anti-slip effect when crawling, and the clamping is tight, which can prevent the marker body 1 from slipping when crawling.

[0043] like Figure 3 As shown, the end of the partition 14 away from the driving shaft 21 is rotatably connected to the stirring shaft 11; the stirring shaft 11 is fixedly connected to the stirring plate 12; the output end of the stirring shaft 11 is fixedly connected to the input end of the driving shaft 21; the stirring shaft 11 is driven to rotate by the driving assembly 6;

[0044] During operation, when it is necessary to drive the clamping block 28 for clamping, first drive the stirring shaft 11 to rotate. When the stirring shaft 11 rotates, it can drive the stirring plate 12 to stir the marking liquid inside the marker body 1 to prevent the marking liquid from solidifying. While stirring, the stirring shaft 11 drives the driving shaft 21 to rotate, and then drives the crown gear 22 to rotate, so that the clamping block 28 is used for clamping. Through the setting of the stirring shaft 11, the marking liquid can be stirred while driving the clamping component 2 to work, avoiding the situation where the marking liquid solidifies for a long time and cannot be marked. At the same time, the partition 14 can separate the marking liquid from the clamping component 2 to prevent the marking liquid from entering the clamping component 2.

[0045] like Figure 2 As shown, a telescopic column 32 is fixedly connected to the bottom of the marker body 1; the end of the telescopic column 32 away from the marker body 1 is fixedly connected to the lower marking plate 3; the end of the lower marking plate 3 away from the telescopic column 32 is clamped with a lower marking sponge 31; the bottom of the marker body 1 is fixedly connected to a lower injection hose 33;

[0046] During operation, when the marker body 1 is moved to the marking position by the moving component 4, the driving component 6 is used to drive the lower marking plate 3 to descend. When descending, the lower marking sponge 31 will contact the marking position, and then the marking work is carried out. While descending, the lower liquid injection hose 33 is stretched, and the marking liquid can be transported to the marking sponge by the lower liquid injection hose 33.

[0047] like Figure 2 and Figure 3 As shown, the driving assembly 6 includes a fixing plate 62; the fixing plate 62 is fixedly connected to the side wall of the marker body 1; the fixing plate 62 side wall is fixedly connected with a connecting column 63; the side wall of the lower marking plate 3 is fixedly connected with a lifting rack 61; a first gear 64 is sleeved on the connecting column 63; the first gear 64 is meshed and connected with the lifting rack 61; the end of the stirring shaft 11 away from the partition 14 is clamped with a hexagonal column 66; the end of the hexagonal column 66 is fixedly connected with a second gear 65; the second gear 65 is meshed and connected with the first gear 64;

[0048] During operation, the second gear 65 is driven by a motor to rotate. The motor is not shown in the figure. When rotating, the second gear 65 will use the hexagonal column 66 to drive the stirring shaft 11 to rotate, and then drive the crown gear 22 to rotate. At the same time, the rotation of the second gear 65 can drive the first gear 64 to rotate, and then use the lifting rack 61 to drive the lower marking plate 3 to descend, so as to achieve marking on the ground. When marking on the ground, the rotation of the second gear 65 also drives the stirring shaft 11 to rotate, so as to achieve stirring of the marking liquid. The first gear 64 is sleeved on the connecting column 63. When the second gear 65 is not needed to drive the first gear 64 to rotate, the first gear 64 can be moved to move the first gear 64 to the fixed plate 62 for a distance, so that the first gear 64 and the second gear 65 are disengaged. In this way, when the clamping assembly 2 is driven to work, the first gear 64 and the second gear 65 can be prevented from driving the lower marking plate 3 to move.

[0049] like Figure 4 As shown, the upper marking component 5 includes a rotating column 51; the rotating column 51 is rotatably connected to the top of the marker body 1; the end of the rotating column 51 away from the marker body 1 is hinged with a connecting arm 53; the end of the connecting arm 53 away from the rotating column 51 is hinged with an upper marking plate 54; the side wall of the upper marking plate 54 is clamped with an upper marking sponge 55; the interior of the rotating column 51 is provided with an upper liquid injection hose 52; the upper liquid injection hose 52 is arranged to penetrate the rotating column 51, and the end away from the rotating column 51 is fixedly connected to the upper marking plate 54;

[0050] During operation, when the marker body 1 is moved to a high place, the upper marking component 5 is used for marking. The rotating column 51 in the upper marking component 5 can be rotated. During the rotation, the angle of the upper marking plate 54 can be adjusted in cooperation with the connecting arm 53. Then, the upper marking sponge 55 is used for marking, and then the infusion is carried out through the upper injection hose 52.

[0051] like Figure 1 As shown, a liquid inlet pipe 13 is fixedly connected to the side wall of the marker body 1;

[0052] During operation, liquid can be infused into the marker body 1 through the liquid inlet tube 13 .

[0053] like Figure 2 As shown, the moving assembly 4 includes a shock absorbing spring 42; the shock absorbing spring 42 is provided with four groups, which are respectively fixedly connected to the bottom of the marker body 1; the end of the shock absorbing spring 42 away from the marker body 1 is fixedly connected to a support plate 41; the bottom of the support plate 41 is provided with a universal wheel 43;

[0054] During operation, when moving, the universal wheel 43 can be damped by the damping spring 42, so that the marker body 1 is in a relatively stable state when moving.

[0055] Working principle of the present invention: In the prior art, the marking of the construction site is achieved by the staff holding the handle and then using the marking sponge on the marking mechanism. However, it is found during use that when marking, the marking is not limited to the ground, and it is possible to mark on the wall or the column. For example, when it is necessary to mark at a high place on the wall or the column, the staff is required to stand on a ladder to mark during the marking process. Since the marking mechanism contains marking liquid, it is heavy, which will make the staff feel tired after marking for a long time. Moreover, when marking for a long time on a lower ground, the staff is required to bend over for a long time to mark, which undoubtedly increases the labor burden of the staff, and the fatigue increases and reduces the work efficiency. In order to prevent such incidents from happening, firstly, a marking device body 1 is added. Inject marking liquid, then use the moving component 4 to control the marker body 1 to move to the position where it needs to be marked. After the movement is completed, if you need to mark the ground, drive the lower marking plate 3 to descend and mark the ground. If you need to mark a high place, drive the clamping component 2 to clamp the column or wall. After clamping and fixing, use the clamping component 2 to drive the marker body 1 to rise, so that the upper marking component 5 is close to the marking place for marking, and the clamping component 2 can be adjusted. Through the setting of the clamping component 2, walls and columns of different thicknesses can be clamped, and then the marking place is marked through the setting of the upper marking component 5. The setting of the marker body 1 can replace manual marking, and the setting of the lower marking plate 3 can facilitate ground marking, avoid manual bending over for marking, and reduce the labor burden of the staff.

[0056] Among them, when marking at a high place, first use the moving component 4 to move the marker body 1 to the wall or column, and then move the two groups of clamping blocks 28 to both sides of the wall or column. After reaching the position, drive the crown gear 22 to rotate. When rotating, the crown gear 22 drives the transmission gear 26 to rotate, and then drives the clamping screw 25 to rotate through the transmission gear 26. When the clamping screw 25 rotates, it drives the two groups of moving plates 27 to move, and then drives the clamping block 28 to approach the wall and clamp it. A roller 29 is set in the clamping block 28, and the roller 29 is driven by a motor set inside the clamping block 28. After clamping, the roller 29 is driven to rotate. When rotating, it drives the marker body 1 to crawl to a high place. When crawling to the vicinity of the marking place, the upper marking component 5 on the marker body 1 is used for marking. The roller 29 is made of rubber, which can play an anti-slip effect when crawling, and the clamping is tight, which can prevent the marker body 1 from slipping when crawling.

[0057] Among them, the second gear 65 is driven to rotate by a motor, and the motor is not shown in the figure. When rotating, the second gear 65 will use the hexagonal column 66 to drive the stirring shaft 11 to rotate, and then drive the crown gear 22 to rotate. At the same time, the rotation of the second gear 65 can drive the first gear 64 to rotate, and then use the lifting rack 61 to drive the lower marking plate 3 to descend, so as to achieve marking on the ground. When marking on the ground, the rotation of the second gear 65 also drives the stirring shaft 11 to rotate, so as to achieve stirring of the marking liquid. The first gear 64 is sleeved on the connecting column 63. When the second gear 65 is not needed to drive the first gear 64 to rotate, the first gear 64 can be moved to move the first gear 64 to the fixed plate 62 for a distance, so that the first gear 64 and the second gear 65 are disengaged. In this way, when the clamping assembly 2 is driven to work, the first gear 64 and the second gear 65 can be prevented from driving the lower marking plate 3 to move.

[0058] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
