Description

Technical Field

[0001] The utility model specifically relates to a hanging self-pressurized wall planing unit for an exterior wall, and belongs to the technical field of building reconstruction tools. Background Art

[0002] As buildings age, the phenomenon of exterior wall peeling becomes increasingly common. This can cause people to question building quality and reduce building performance, especially in older residential areas where peeling is frequent. Treatment methods, labor, and costs are all significant expenditures in building maintenance costs. Before the exterior wall peels off, irregular, slight cracks will appear on the surface, creating hollows between the base layer and the finishing layer. After a period of time, rainwater erosion and repeated heating and cooling will cause the base layer and the finishing layer to completely separate, causing the finishing layer to fall off. After the masonry structure is damaged, the exterior wall surface will develop wet spots under the influence of rainwater, and even diffuse wet spots will occur, reducing the overall effect of the finishing, seriously affecting the building's aesthetics, and even endangering people's personal safety.

[0003] A common way to deal with peeling wall paint is to remove the wall paint and repair it. A common way to remove the wall paint is to plane the wall. This type of technology is commonly used on the interior walls of buildings. It is mainly used to level the wall to ensure the flatness and smoothness of the surface. Preparation work is required before construction. First, confirm the material and condition of the wall to be constructed, ensure that there are no obvious bumps on the wall surface, and whether debris and dust are cleaned up. Check whether the corners of the wall meet the requirements and take protective measures where necessary. When constructing on the interior walls of a building, it is necessary to build scaffolding according to the height and scope of the construction to ensure that construction workers can operate and move safely. When the exterior wall of a high-rise building peels off, the treatment method for the interior wall of the building is not universal. Due to factors such as height restrictions and safety impacts, the means of treating the exterior wall of the building are limited. Generally, there are two methods. One is to use large-scale lifting equipment to operate around the building. The operation of the wall at a high-rise location is also restricted. The other is for workers to hang outside to repair it. However, since most of the exterior walls to be treated already have hollows and peeling of the wall skin, the degree of separation and position are different. When the workers peel and plan the exterior wall skin, there is a situation where the wall skin falls off unexpectedly and cannot be controlled by the workers. This affects the safety of the workers themselves, poses a safety hazard, and also puts great pressure on the maintenance difficulty and labor costs of repairing the exterior wall. At present, there is no adaptive tool that can deal with local walls on demand. Utility Model Content

[0004] The purpose of the utility model is to provide a hanging self-pressurized wall planing unit for external walls, so as to solve the above problems.

[0005] The lifting mechanism is a kind of lifting mechanism that lifts up and down of described lifting mechanism, and the lifting mechanism of lifting up and down of described lifting mechanism is a kind of lifting mechanism that lifts up and down of described lifting mechanism.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The utility model can realize the planing treatment of the local area of ​​the exterior wall without the need for manual external hanging treatment through the mutual cooperation between the main carrier plate, the lifting drive part, the moving block, the wall planer and the two regulating rods. The construction personnel use the building window as the position of the external wall planer unit, and place the utility model on the corresponding area of ​​the building exterior wall that needs to be planed by hanging. The mutual cooperation between the main carrier plate, the lifting drive part, the moving block and the two regulating rods can ensure that the wall planer maintains normal basic performance while also having the performance of cooperating with the wall planer to perform local secondary pressing on the wall surface. Specific fine-tuning is performed according to the wall conditions to ensure the uniform wall treatment effect of the wall planer, which is beneficial for use on suspended walls of a single structure, avoids the construction personnel's external hanging or the use of large lifting equipment to operate the exterior wall, improves the safety of exterior wall treatment, reduces the treatment process, and saves treatment and maintenance costs.

In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0021] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0022] Specific implementation method 1: Combination Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 Describe this embodiment. This embodiment includes a main carrier plate 1, a lifting drive member 2, a moving block 3, a wall planer 4 and two regulating rods 5. The main carrier plate 1 is arranged vertically, and the lifting drive member 2 and the moving block 3 are arranged in sequence from top to bottom on the outside of the main carrier plate 1 along the length direction of the main carrier plate 1. The lifting drive member 2 drives the moving block 3 to make reciprocating lifting and lowering movements along the length direction of the main carrier plate 1. The wall planer 4 is arranged below the main carrier plate 1, and the two regulating rods 5 are arranged side by side between the moving block 3 and the wall planer 4. The upper end of each regulating rod 5 slides with the moving block 3, and the middle part of each regulating rod 5 is hinged to the main carrier plate 1. The lower end of each regulating rod 5 is hinged to the wall planer 4. The wall planing surface of the wall planer 4 is set toward the outer wall 15 of the building. When the moving block 3 is in the rising limit position, the wall planer 4 is in a wall-planing state. When the moving block 3 is in the falling limit position, the wall planer 4 is in a wall-planing state.

[0023] During specific use, the lifting drive component 2 is provided with an electric control program, which is an existing program. The corresponding control terminal is controlled by the construction personnel. The lifting amplitude is controlled by the electric control program, thereby adjusting the distance between the planing surface of the wall planer 4 and the outer wall 15 of the building.

[0024] When the utility model is used, it is ensured that the main carrier plate 1 is stably attached to the building outer wall 15, thereby providing effective support and positioning support for the subsequent secondary wall-attaching positioning of the wall planer 4.

[0025] Furthermore, the wall planer 4 is an existing device, and its working principle is the same as that of the existing wall planer. Other necessary components of the wall planer 4 not mentioned in this embodiment can be arranged on the main carrier plate 1 for use in conjunction with the wall planer 4.

[0026] In this embodiment, when the lifting drive member 2 drives the moving block 3 to make an upward movement, the wall planer 4 is in a state of waiting for wall planing. When the lifting drive member 2 drives the moving block 3 to make a downward movement, the motor on the wall planer 4 is started to make the planer rotate at high speed so that it is in a wall planing state, which can make the warped areas in the exterior wall skin fall off quickly and uniformly, remove uneven positions, and peel off impurities contained in the warped areas of the wall, and perform a unified treatment process on the part of the exterior wall to be repaired. The treatment area should be larger than the area where the exterior wall skin is warped. The specific size control is carried out according to the design requirements. After planing, ensure that the surface of the exterior wall 15 of the building is in a smooth and flat state.

[0027] In this embodiment, a cushion layer may be further provided between the lifting drive member 2 and the main carrier plate 1 to level the axial position of the lifting drive member 2 to form an optimal arrangement position adapted to the moving block 3 .

[0028] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. The lifting drive member 2 is a hydraulic cylinder. The lifting drive member 2 includes a cylinder 2-1 and a piston rod 2-2. The cylinder 2-1 is fixedly connected to the main carrier plate 1. One end of the piston rod 2-2 is passed through the cylinder 2-1, and the other end of the piston rod 2-2 is connected to the top of the moving block 3.

[0029] Furthermore, the lifting drive member 2 is an existing electronically controlled hydraulic cylinder, and its working principle is the same as that of an existing hydraulic cylinder.

[0030] Specific embodiment three: This embodiment is a further limitation of specific embodiment two. The main carrier board 1 includes a main board 1-1, a first transverse board 1-2 and a second transverse board 1-3. The main board 1-1 is arranged vertically, and the first transverse board 1-2 and the second transverse board 1-3 are arranged side by side from top to bottom on the outer side of the main board 1-1. The length direction of the first transverse board 1-2 is in the same direction as the width direction of the main board 1-1. The lower end of the piston rod 2-2 passes through the first transverse board 1-2 and is connected to the top of the moving block 3; the middle parts of the two regulating rods 5 are hinged to the two ends of the second transverse board 1-3 respectively.

[0031] Furthermore, a slide groove 8 is processed on the side of the main board 1-1 away from the building outer wall 15, and the slide groove 8 is arranged between the first horizontal plate 1-2 and the second horizontal plate 1-3. The moving block 3 is connected to the main board 1-1 through the slide groove 8, and the piston rod 2-2 on the lifting drive 2 passes through the first horizontal plate 1-2 and is connected to the moving block 3, so that the lifting drive 2 drives the moving block 3 to make an upward or downward movement state, and the upper ends of the two regulating rods 5 slide with the moving block 3, and the middle parts of the two regulating rods 5 are respectively hinged to the two ends of the second horizontal plate 1-3, to ensure that the moving block 3 can drive the wall planer 4 close to or away from the building outer wall 15 through the two regulating rods 5 when moving up and down.

[0032] Specific embodiment four: This embodiment is a further limitation of specific embodiments one, two or three. An inclined slot 6 is processed on both sides of the moving block 3. The lower end of each inclined slot 6 is set close to the main carrier plate 1, and the high end of the inclined slot 6 is set away from the main carrier plate 1. The regulating rods 5 are set in a one-to-one correspondence with the inclined slots 6. The upper end of each regulating rod 5 is set in its corresponding inclined slot 6, and the upper end of each regulating rod 5 slides back and forth along the length direction of the inclined slot 6.

[0033] Furthermore, when the moving block 3 makes an upward or downward movement driven by the lifting drive member 2, the upper end of each regulating rod 5 slides back and forth along the length direction of the inclined slot 6, so that the lower end of each regulating rod 5 drives the planer 4 to make a reciprocating movement close to or away from the building outer wall 15, thereby planing the wall surface at the corresponding position according to specific needs, avoiding accidental scratches and damage to the planer 4 when planing is not required.

[0034] Specific embodiment five: This embodiment is a further limitation of specific embodiment four. Each regulating rod 5 is processed with a strip protrusion 5-1 on both sides, and the inner wall of the inclined slot 6 is processed with a strip groove 6-1 that matches the strip protrusion 5-1. The middle part of each regulating rod 5 is processed with a first connecting hole 5-3, and the lower end of each regulating rod 5 is processed with a second connecting hole 5-4.

[0035] Furthermore, the inner side of the strip protrusion 5-1 and the inner side of the regulating rod 5 are in the same plane, ensuring that the semi-groove structure formed between the outer side of the strip protrusion 5-1 and the outer side of the regulating rod 5 has a sufficient groove depth, thereby improving the connection strength between the regulating rod 5 and the inclined slot 6, and ensuring the stable performance of the regulating rod 5 moving in the inclined slot 6.

[0036] Furthermore, the strip protrusion 5-1 on each regulating rod 5 cooperates with the inclined slot 6 on the moving block 3 to ensure that the moving block 3 can drive the regulating rod 5 to move during the up and down movement. Each regulating rod 5 is hinged to the second horizontal plate 1-3 through the first connecting hole 5-3, and each regulating rod 5 is hinged to the wall planer 4 through the second connecting hole 5-4, so that the regulating rod 5 can make the wall planer 4 approach the building outer wall 15 or move away from the building outer wall 15 when moving.

[0037] Specific embodiment six: This embodiment is a further limitation of specific embodiment two. The movable block 3 is processed with a protrusion 7 on the side facing the main carrier plate 1. The protrusion 7 is a T-shaped block or a dovetail-shaped block. The narrow side of the protrusion 7 is fixedly connected to the movable block 3. The outer side of the main carrier plate 1 is processed with a slide groove 8 that cooperates with the protrusion 7 along its length direction.

[0038] Furthermore, the moving block 3 is connected to the main carrier plate 1 through the protrusion 7 and the slide groove 8. When the lifting drive member 2 drives the moving block 3 to slide up and down, the protrusion 7 and the slide groove 8 can ensure that the moving block 3 slides up and down smoothly on the main carrier plate 1, avoiding deviation and loosening during sliding.

[0039] Specific embodiment seven: This embodiment is a further limitation of specific embodiment six, and the sliding groove 8 is provided between the first transverse plate 1-2 and the second transverse plate 1-3.

[0040] Specific embodiment eight: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six or seven, in which an outer cover 9 is detachably connected to the outside of the main carrier board 1 .

[0041] Furthermore, the outer cover 9 is a rectangular cover with an opening at the bottom, which can protect the main carrier plate 1 and the lifting drive member 2, moving block 3 and two regulating rods 5 arranged thereon by snapping together, thereby reducing the risk of dust and other impurities such as dust falling into the main carrier plate 1 and the lifting drive member 2 and moving block 3 arranged thereon during the planing process and making them difficult to clean, which is beneficial to maintaining the durable performance of the utility model. The exposed setting of the wall planer 4 is beneficial to the heat dissipation during its own use and the scattering of wall debris generated during planing.

[0042] Specific embodiment nine: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six, seven or eight. This embodiment also includes a positioning support frame. The upper end of the main carrier plate 1 is a connecting end. A positioning support frame is provided on the connecting end of the main carrier plate 1. The positioning support frame includes a telescopic rod 11 and a hanging frame 12. The hanging frame 12 is an existing hook structure, which can be a large steel hook structure. The lower end of the telescopic rod 11 is connected to the connecting end of the main carrier plate 1, and the upper end of the telescopic rod 11 is detachably connected to the building window through the hanging frame 12.

[0043] In this embodiment, the telescopic rod 11 is a telescopic rod of the existing sleeve structure, and may also be a cylinder electrically controlled telescopic rod.

[0044] Specific embodiment ten: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six, seven, eight or nine, and the hanging rack 12 includes a long vertical plate 12-1, a short vertical plate 12-2, a horizontal plate 12-3 and an inclined plate 12-4. The horizontal plate 12-3 is horizontally arranged, and the two ends of the horizontal plate 12-3 are respectively provided with a long vertical plate 12-1 and a short vertical plate 12-2. The long vertical plate 12-1 and the short vertical plate 12-2 are vertically arranged in parallel, one end of the short vertical plate 12-2 is fixedly connected to one end of the horizontal plate 12-3, and the other end of the short vertical plate 12-2 is fixedly connected to one end of the inclined plate 12-4. The high end of the inclined plate 12-4 is fixedly connected to the long vertical plate 12-1, and the low end of the inclined plate 12-4 is connected to the telescopic rod 11.

[0045] Furthermore, the thickness of the short vertical board 12-2 is less than that of the long vertical board 12-1. The long vertical board 12-1 is the main supporting member, which can be fixedly or detachably connected indoors to achieve the overall support effect of the utility model. The length of the horizontal board 12-3 determines the horizontal adjustment range of the mounting bracket 12. During specific adjustment, the horizontal board 12-3 is slightly moved toward the outdoors or indoors by positioning the long vertical board 12-1 indoors, thereby ensuring that the horizontal board 12-3 drives the short vertical board 12-2 to move synchronously until the main carrier board 1 is closely attached to the building's exterior wall 15.

[0046] Furthermore, when the long vertical board 12-1 is not fixedly connected indoors, the mounting bracket 12 can also be moved horizontally along the length direction of the building window. The horizontal movement of the mounting bracket 12 drives the main carrier plate 1, the lifting drive part 2, the moving block 3 and the wall planer 4 to move synchronously, thereby achieving the local micro-movement planing effect of the wall planer 4, and realizing the process from point planing to linear planing.

[0047] The working principle of this utility model is:

[0048] After the main carrier plate 1 is placed tightly against the building outer wall 15, the lifting drive 2 is started to drive the moving block 3 to move up or down, so that the moving block 3 drives the wall planer 4 to move away from or close to the building outer wall 15 through the two control rods 5. When the wall planer 4 is close to the building outer wall 15, the wall planer 4 is started to plan the wall.

[0049] The working process of the positioning support frame in conjunction with the utility model is as follows:

[0050] First, the construction workers install the positioning support frame on the main carrier plate 1, place the positioning support frame at the window, and use the window to place one side of the wall planing unit on the positioning support frame on the wall of the building's exterior wall 15. One side of the main carrier plate 1 is against the building's exterior wall 15, and the planing surface of the wall planing machine 4 is facing the side of the building's exterior wall 15. By starting the lifting drive 2, the moving block 3 is driven to make an upward or downward movement. When the moving block 3 is doing an upward movement, the two regulating rods 5 drive the wall planing machine 4 away from the wall of the building's exterior wall 15. At this time, the wall planing machine 4 is in a state of waiting for wall planing. When the moving block 3 is doing a downward movement, the motor on the wall planing machine 4 is started, and the two regulating rods 5 drive the wall planing machine 4 to stick close to the wall of the building's exterior wall 15. The wall planing machine 4 is started to work, completing the preliminary work of repairing the building's exterior wall 15.

[0051] After the initial planing is complete, workers spray the surface with water before further finishing, such as leveling, scraping, and trimming corners. Attention is also paid to the smooth transitions between walls. After the plastering and leveling process, allow some time for the plaster mortar to fully cure before lightly sanding the entire surface with sandpaper to repair minor imperfections and sand marks.
