Abstract

This invention belongs to the field of building marking technology, specifically relating to a marking device for the surface of building structures. It includes: a base plate with a sliding groove on its upper surface and a gripping rod fixedly connected to its lower surface; a positioning plate vertically fixed to the upper side of the base plate and perpendicular to the sliding groove; a stamp disposed on the base plate and slidingly engaged with the sliding groove; and a control mechanism for controlling left and right movement to align the marking position on the structure. This device enables remote operation from the ground via the gripping rod, allowing for high-altitude marking without climbing, eliminating safety hazards. The positioning plate abuts against the side wall of the structure to form a positioning reference.

Description

Technical Field

[0001] This invention belongs to the field of building identification technology, and specifically relates to a marking device for the surface of building structures. Background Technology

[0002] In building construction, markings are printed on the surfaces of beams and columns to indicate their location and prefabricated segments. Similarly, markings are printed on the surfaces of cable trays or various pipelines to indicate their specifications, uses, and routes. Marking is commonly required for structures located at heights. Traditionally, this involves manual hand-held stamping, requiring climbing support frames. This manual operation is problematic because it's too close to the work surface, leading to significant positional errors. Furthermore, it's difficult to cross-reference marks, resulting in uneven markings. In short, existing manual close-range marking methods suffer from inaccurate printing positions, difficulty controlling the seal's fit to the cable tray or pipeline surface, leading to blurry and misaligned markings, and also pose safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this invention is that existing marking devices have large errors, low marking efficiency, and high safety risks during high-altitude operations.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A marking device for the surface of building structures, comprising: The substrate has a sliding groove on its upper surface and a gripping rod fixedly connected to its lower surface. The positioning plate is vertically fixed to the upper side of the base plate and is perpendicular to the sliding groove. The stamp is set on the substrate and slides in conjunction with the sliding groove; The control mechanism is used to control the left and right movement, thereby aligning the marking position on the structure.

[0005] Compared with the prior art, the present invention employing the above structure has the following advantages: 1) Operators can hold the pole on the ground to lift the device to the high-altitude structure without climbing the support frame or working at height, realizing remote safe operation, completely eliminating the safety hazards of working at height, and reducing labor intensity.

[0006] 2) The positioning plate is vertically fixed to the upper side of the base plate and perpendicular to the sliding groove. The stamp slides and engages with the sliding groove. The direction of movement is constrained by the sliding groove, which avoids the stamp from being crooked or offset. The marking positioning is accurate and reliable, and the problem of uneven marking is solved.

[0007] 3) The control mechanism is used to control the left and right movement of the stamp. The operator can make fine adjustments to the stamp according to the marking position requirements to achieve the marking position on the surface of the structure, ensuring that the markings maintain a consistent benchmark before and after each marking, and significantly improving the overall aesthetics and consistency of the markings.

[0008] 4) The device has a compact overall structure and all components work together. One person can independently complete the entire process of lifting, centering and marking without the need for auxiliary personnel. Compared with the traditional climbing operation method, it greatly improves the marking efficiency and is suitable for surface marking operations on various building structures such as beams, columns, cable trays and pipes.

[0009] As a preferred option, a further technical solution to the above structure is: The control mechanism is positioned opposite each other on both sides of the substrate. The control mechanism includes a connecting rod, a control line, and a linkage line. The middle part of the connecting rod is rotatably mounted on the side wall of the substrate. One end of the linkage line is connected to the stamp, and the other end is connected to the upper end of the connecting rod. The upper end of the control line is connected to the lower end of the connecting rod, and the lower end of the control line is mounted on the lower part of the grip rod.

[0010] The beneficial effects obtained from the above features are: the left and right movement of the seal can be remotely controlled through the lever principle, and the operator can make fine adjustments for centering without having to climb, thus improving the safety and accuracy of the operation.

[0011] The length of the lower end of the connecting rod is less than the length of the upper end of the connecting rod.

[0012] The beneficial effect obtained from the above features is that by using the leverage ratio to amplify the displacement, a small movement at the control end can drive the seal to produce a large range of movement.

[0013] The stamp consists of a body with markings on its surface and a card holder. The body is embedded in the card holder, and a laser light is provided at the front end of the card holder to emit light, which is projected onto the surface of the structure that needs to be marked.

[0014] The beneficial effects obtained from the above features are as follows: the laser light, as a visual auxiliary positioning device, enables the operator to accurately judge the alignment of the stamp and the marking position on the ground, greatly improving the accuracy of the marking position.

[0015] A light-shielding plate is installed on the lower side of the laser light.

[0016] The beneficial effects obtained from the above features are: the light shield can effectively block the direct light from the laser lamp, preventing the operator from looking directly at the light source when looking up, thus protecting the eyes.

[0017] The control line consists of a wire core and a wire tube. At the upper end of the control line, a tube limit buckle is installed at the end of the wire tube, which abuts against the inner wall surface of the substrate. The wire core passes through the substrate and is connected to the lower end of the connecting rod. At the lower end of the control line, the wire tube is installed on the surface of the fixed seat, the wire core passes through the fixed seat and is connected to the wrench. Rotating the wrench pulls the wire core out of the fixed seat. The fixed seat is fixedly installed at the lower end of the gripping rod.

[0018] The beneficial effects obtained from the above features are: the use of a structure similar to a brake line ensures stable transmission and high friction, and can keep the stamp position locked in the non-operating state, ensuring the consistency of the marking position in multiple markings.

[0019] There are two symmetrical grips, which are telescopic and their length is adapted to the user's operation on the ground.

[0020] The beneficial effects obtained from the above features are: the dual grip bar structure makes the device more stable when lifted, and the telescopic bar can adapt to operators of different heights and marking positions at different heights, improving the comfort of operation and the scope of application.

[0021] The control line is attached to the surface of the grip or installed inside the grip.

[0022] The beneficial effects obtained from the above features are: the control lines can be arranged flexibly, avoiding tangling or wear caused by exposed lines, and improving the overall integrity and service life of the device.

[0023] The connecting lines on both sides of the seal are the same, and this connecting line runs through the seal. There is a wire clamp inside the seal to lock the seal in place on the connecting line.

[0024] The beneficial effects obtained from the above features are: synchronous linkage between the two sides can be achieved through a single connecting line, resulting in a simple structure; it is easy to pre-adjust the stamp position during the marking operation, making it highly adaptable and convenient to operate.

[0027] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0028] See Figures 1-4 The present invention provides a marking device for the surface of building structures, including a base plate 1, a positioning plate 4, a stamp 5 and a control mechanism 6.

[0029] The substrate 1 has a sliding groove 3 on its upper surface and a gripping rod 2 fixedly connected to its lower surface. Positioning plate 4 is vertically fixed to the upper side of base plate 1 and is perpendicular to sliding groove 3; Seal 5 is set on substrate 1 and slides in cooperation with sliding groove 3; Control mechanism 6 is used to control the left and right movement of stamp 5, thereby aligning the marking position of the structure.

[0030] The stamp 5 is supported by the base plate 1, and the stamp 5 is remotely controlled to be marked by the grip rod 2. This allows for remote marking of the surface of high-altitude structures. Using this device eliminates the need to climb, saving time and increasing the safety of ground operations.

[0031] Alternatively, control mechanisms 6 are respectively disposed on both sides of the substrate 1. The adjustment mechanism includes a connecting rod 62, a control line and a linkage line 61. The middle part of the connecting rod 62 is rotatably mounted on the side wall of the substrate 1. One end of the linkage line 61 is connected to the stamp 5 and the other end is connected to the upper end of the connecting rod 62. The upper end of the control line is connected to the lower end of the connecting rod 62, and the lower end of the control line is installed at the lower part of the gripping rod 2.

[0032] The upper end of the control line on one side of substrate 1 retracts, causing the lower end of the connecting rod 62 to move towards substrate 1. Utilizing the lever principle, the upper end of the connecting rod 62 moves away from substrate 1, thereby moving the stamp 5 to one side to adjust its position. The movement of the stamp 5 causes the upper end of the connecting rod 62 on the other side of substrate 1 to move towards substrate 1. Utilizing the lever principle, the lower end of the connecting rod 62 on the other side of substrate 1 pulls the control line, lengthening it. In this design, the control mechanisms 6 on both sides work together on the stamp 5, with one side being the active control end and the other the stabilizing end, interacting with each other.

[0033] See Figure 1 , Figure 2 In the above embodiment, the substrate 1 is a U-shaped plate, and the two side walls are used to install the control mechanism 6. The side wall surface is fixedly connected to the bearing 63. The bearing 63 is connected to the connecting rod 62 through the rotating shaft 64. The bearing 63 is provided with a through hole 9 on the lower side for passing through the control line. When the lower end of the connecting rod 62 rotates to contact the side wall, it is the maximum adjustment range of the control mechanism 6.

[0034] The control line and linkage line 61 can be made of high-strength and flexible materials such as steel wire and nylon rope. Furthermore, the lower end length of the connecting rod 62 is less than the upper end length; specifically, the ratio of the lower end length to the upper end length of the connecting rod 62 can be selected as 1:(3-5). The lower end and upper end of the connecting rod 62 are set at an angle, which can be selected as 135 degrees.

[0035] When the upper end of the connecting rod 62 rotates outward, it is accompanied by a downward movement. The connecting line 61 may press against the edge of the substrate 1. Optionally, a wrap angle 10 is added at the edge of the substrate 1 to avoid wear. At the same time, since the upper end of the connecting rod 62 has a height change, the pulling direction of the connecting line 61 on the stamp 5 is floating. To eliminate the floating effect, a wire buckle 8 is provided on the surface of the substrate 1. The wire buckle 8 keeps the connecting line 61 pulling the stamp 5 horizontally.

[0036] To facilitate the installation of the connecting line 61, a window 12 is provided on the surface of the positioning plate 4 for installing the connecting line 61, while also avoiding obstructing the rotation of the connecting rod 62 on the same side.

[0037] In a preferred embodiment of the control line, the control line consists of a wire core 65 and a wire tube 66. At the upper end of the control line, a tube limiting buckle 661 is installed at the end of the wire tube 66. The tube limiting buckle 661 abuts against the inner wall surface of the substrate 1. The wire core 65 passes through the substrate 1 and is connected to the lower end of the connecting rod 62. At the lower end of the control line, the wire tube 66 is installed on the surface of the fixing seat 67. The wire core 65 passes through the fixing seat 67 and is connected to the wrench 68. The wrench 68 is rotated to pull the wire core 65 out of the fixing seat 67. The fixing seat 67 is fixedly installed at the lower end of the gripping rod 2.

[0038] In this embodiment, the control wire on one side has its core 65 offset at the upper end of the conduit 66, meaning the upper end of the core 65 extends a greater length beyond the conduit 66, while the lower end extends a shorter length. The tip of the wrench 68 presses against the surface of the fixing base 67. Figure 7 As shown; on the other side, the control line has its core 65 offset at the lower end of the conduit 66, meaning the lower end of the core 65 extends significantly beyond the conduit 66, and the tip of the wrench 68 is in a position to pull the core 65 out, as shown. Figure 8 As shown.

[0039] As one embodiment of the linkage line 61, the linkage lines 61 on both sides of the seal 5 are the same. The linkage line 61 passes through the seal 5 and its two ends are connected to the connecting rods 62 on both sides respectively. The seal 5 is provided with a wire clip (not shown, but a common clip can be used). The wire clip is used to lock the position of the seal 5 on the linkage line 61. This embodiment facilitates the pre-adjustment of the position of the seal 5.

[0040] In this plan, see Figure 1 , Figure 2 The stamp 5 consists of a body with markings on its surface and a holder 7. The body is embedded in the holder 7. A laser light 11 is provided at the front end of the holder 7 to emit light, which is projected onto the surface of the structure to be marked. The stamp 5 body is a commercially available standard architectural stamp 5. The holder 7 is an outer sleeve structure adapted to this device. The holder 7 is slidably connected to the base plate 1. Specifically, two parallel sliding grooves 3 are provided, see [link to relevant documentation]. Figure 6 The bottom of the card holder 7 is fixedly connected to the slider, and the lower end of the slider is fixedly installed with the stop block 13. The double sliding groove 3 ensures the positive direction of the stamp 5 and prevents the stamp 5 from being crooked. The stop block 13 prevents the stamp 5 from separating from the substrate 1.

[0041] As an alternative, see Figure 5 The card holder 7 includes a base plate 72, on the surface of which four opposing locking corner plates 71 are fixedly attached. Protective side plates 73 are fixedly attached to the perimeter of the base plate 72, and a gap 74 is provided between the protective side plates 73 and the locking corner plates 71. The distribution of the four locking corner plates 71 is adapted to the body of the stamp 5 for clamping and fixing the stamp 5. The gap 74 provides operating space, facilitating the connection of the card holder 7 to other components such as the connecting wire 61, and providing installation space for electronic components such as the battery and chip of the laser lamp 11.

[0042] Optionally, the stamp 5 body includes an ink chamber, the surface of which is provided with a sponge pad, and the heated surface of the sponge is provided with a label card. Optionally, a label sticker is provided on the surface of the stamp 5 body.

[0043] Furthermore, a light shield is provided on the lower side of the laser light 11. The laser light 11 is located on the center line of the stamp 5. The laser light 11 allows the user to easily observe the alignment of the stamp 5 with the center line of the cable tray. The light shield blocks the user's line of sight from directly looking at the light source of the laser light 11, thus avoiding eye injury.

[0044] In this design, two grip levers 2 are symmetrically arranged. The grip levers 2 are telescopic rods, with a length adapted to the user's ground operation. The control cable is attached to the surface of the grip lever 2 or installed inside the grip lever 2.

[0045] The surface of the substrate 1 is provided with a scale to facilitate the positioning of the stamp 5.

[0046] The following describes the operational relationship of each component in the technical solution through the use of the marking device on the surface of this building structure: First, when using the device to mark the surface of cable trays, the width data of the cable tray is obtained; then, based on the width data, the position of the stamp 5 on the linkage line 61 is pre-adjusted, and the stamp 5 can be pulled directly, with the pulling force overcoming the clamping force of the wire clamp, adjusting it to a position where the distance between the center line of the stamp 5 and the positioning plate 4 is approximately half the width of the cable tray; the laser light 11 is turned on, and then the base plate 1 is lifted using the holding rod 2, so that the positioning plate 4 is pressed against the side wall of the cable tray, and the marking is then applied. Stamp 5 corresponds to the lower surface of the cable tray; the position of stamp 5 can be observed by the light of laser lamp 11, and the alignment can be easily observed from the ground. The left and right positions of stamp 5 can be finely adjusted by controlling the two control mechanisms 6. Through actual operation experiments, it has been verified that the error is within the allowable range; after the light of laser lamp 11 is aligned with the center line of the cable tray, push the base plate 1 upward by holding the lever 2 to make the mark imprinted on the cable tray; lower the base plate 1, move the user forward, and put the positioning plate 4 against the side wall of the cable tray again to maintain the original position of stamp 5, and then push the base plate 1 directly.

[0047] In this scheme, the control lines at both ends are linked. When one side pulls the stamp 5, the stamp 5 will not reset or move if the other side does not provide a reverse force. In this scheme, the wire core 65 and the wire tube 66 are similar to bicycle brake cables. The wire core 65 is a steel wire with supporting force. The wire core 65 is sleeved with the wire tube 66. The thread is long and the internal friction is large. Without moving the wrench 68, the wire core 65 is not easy to move, thus ensuring that the lower end of the connecting rod 62 is fixed. Therefore, the position of the first marking can be inherited during the second marking operation.

[0048] To further ensure the stability of the stamp 5 position after one adjustment, the connecting rod 62 and the rotating shaft 64 are configured to be tightly fitted. When the lower end of the connecting rod 62 is not actively controlled by human, the connecting rod 62 will not move, thereby preventing the connecting line 61 from becoming loose.

[0049] The beneficial effects of this device: By using a base plate to support the stamp and a grip rod to achieve remote control from the ground, operators can complete the marking work on the surface of high-altitude structures without climbing to high places, effectively avoiding the safety risks of working at heights and improving the ease of operation.

[0050] The stamp slides into the sliding groove and is positioned against the side wall of the structure by the positioning plate, ensuring that the stamp moves in a stable and unbiased direction. The control mechanism uses the lever principle to make fine adjustments left and right, which can accurately align the marking position and avoid positional errors caused by manual operation.

[0051] The front end of the card is equipped with a laser light, which projects the laser beam onto the marking surface. The operator can directly observe the alignment of the stamp with the center line of the structure from the ground. With the help of a light shield to protect the eyes, the alignment accuracy and operational safety are significantly improved.

[0052] The control line adopts a core and conduit structure, similar to a gate design, with high internal friction. It can keep the stamp position locked in the non-operational state, ensuring consistent marking position for multiple markings, making it suitable for batch operations.

[0053] The grip is telescopic, adaptable to operators of different heights and marking positions at different heights; the control line can be attached to the surface of the grip or built into it to avoid tangling and wear; the stamp position can be pre-adjusted via the wire clip, suitable for cable trays or pipes of different widths.

[0054] The stamp itself can be replaced with identification cardboard or adhesive stickers, which can be used for both ink printing and sticker application to meet the marking needs of different construction scenarios. The markings are clear and have good adhesion.

[0055] This device eliminates the need for repeated alignment and climbing, allowing a single person to efficiently complete continuous marking operations, significantly improving the speed and consistency of label printing, and contributing to standardized and regulated management of construction sites.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
