Description

Technical Field

[0001] This invention relates to the field of mechanical equipment for interior wall decoration construction, specifically to a device for creating horizontal ridges on interior walls. Background Technology

[0002] In residential interior wall decoration construction, after the basic plastering of the wall surface is completed, horizontal decorative treatment is needed to enhance the sense of layering, aesthetics, and adhesion of subsequent paint. The conventional construction process is as follows: a composite slurry made of cement slurry, fine sand, and construction adhesive is applied a second time to the plastered wall surface. A square sponge is then used to sweep the slurry surface at a uniform speed, creating regular, equidistant horizontal decorative textures on the wall through regular, reciprocating sweeping motions.

[0003] Currently, this process relies entirely on manual operation, which presents several industry pain points: First, the uneven pressure and unstable walking speed of manual brushing easily lead to problems such as inconsistent horizontal line depth, disordered spacing, and blurred local textures, resulting in poor overall wall surface consistency; Second, indoor high-altitude wall construction requires workers to erect trestles and scaffolding for high-altitude operations, posing safety hazards such as falls from heights and spillage of mortar; Third, manual construction is inefficient, and large-area wall construction is time-consuming, labor-intensive, and costly, failing to meet the schedule requirements of batch high-end decoration construction; Fourth, manual brushing with a handheld sponge is repetitive and physically demanding, leading to fatigue during prolonged work and further reducing the stability of construction quality.

[0004] Existing wall plastering and texture forming machinery has a limited range of structures, mostly consisting of fixed-size columns, making it unsuitable for varying interior ceiling heights. Vertical lifting lacks precise equidistant control, hindering the uniform distribution of horizontal lines. End-effector avoidance relies heavily on electronic components, making them prone to malfunction in harsh construction environments. Exposed transmission structures are susceptible to dust accumulation and jamming, and there is no adaptive sweeping structure suitable for cement slurry + fine sand + adhesive composite slurry, failing to meet the refined construction needs of secondary horizontal texturing on interior walls. Based on these technological shortcomings, there is an urgent need to develop an automated wall texturing device that is adaptable to indoor construction, adaptable to ceiling heights, provides precise equidistant forming, utilizes purely mechanical avoidance mechanisms, and boasts high stability. Summary of the Invention

[0005] The purpose of this invention is to provide an indoor wall panel horizontal stripe device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an indoor wall surface horizontal ribbing device, characterized in that it includes a first motor, a first transmission combination sleeve, a support, a first transmission crossbar, a sleeve support, a jack, a truss module, a second transmission combination sleeve, a transmission upright, a second bevel gear, a vertical sliding block, and a horizontal ribbing working module.

[0007] The first motor is fixedly installed on the support, and the output end of the first motor is connected to the first transmission combination sleeve. The first transmission combination sleeve is in transmission cooperation with the first transmission crossbar, and the end of the first transmission crossbar is fixedly equipped with a first bevel tooth.

[0008] The truss module is vertically erected on the sleeve support and adopts a segmented and assembleable structure. A jack is installed inside the sleeve support. The bottom end of the jack is fixed inside the sleeve support and the top end of the jack supports the lower end of the truss module. The jack is equipped with a ratchet and tooth one-way self-locking assembly.

[0009] A second transmission assembly sleeve is fixedly provided on the inner side of the lower end of the truss module. The second transmission assembly sleeve integrates a first bevel gear and a second bevel gear for meshing. The second bevel gear is fixedly installed at the bottom end of the transmission upright. The transmission upright is vertically rotatable and arranged in the cavity inside the truss module. The transmission upright is threadedly connected to the vertical sliding block.

[0010] The vertical sliding block is fixedly connected to the horizontal pattern working module on the outside; the horizontal pattern working module includes a fixed support block, a second motor, a second transmission crossbar, a guide rod, a collision protection rod, an indicator rod, a telescopic rod, a fixed horizontal pattern working head, a movable horizontal pattern working head, a horizontal sliding block, and a spring;

[0011] The fixed support block is fixedly connected to the vertical sliding block. A second motor, a parallel second transmission crossbar, and a guide rod are fixedly installed on the fixed support block. The second transmission crossbar is driven to rotate by the second motor. A horizontal sliding block is slidably assembled on the second transmission crossbar and the guide rod. A telescopic rod is installed on the outside of the horizontal sliding block. The end of the telescopic rod is connected to a movable cross-grooving working head. A fixed cross-grooving working head is fixedly installed on the outside of the fixed support block. A spring is sandwiched between the fixed cross-grooving working head and the movable cross-grooving working head.

[0012] The fixed support block is equipped with an anti-collision rod and an indicator rod at its end. When the anti-collision rod touches the wall end limiting structure, the linkage indicator rod drives the telescopic rod to retract, causing the movable horizontal working head to detach from the wall surface, thus achieving automatic end avoidance.

[0013] The first motor operates at a fixed speed, sequentially driving the transmission upright to rotate at a fixed angle through the first transmission crossbar, the first bevel gear, and the second bevel gear, thereby driving the vertical sliding block to move up and down at equal intervals along the vertical of the transmission upright; the second motor drives the working head to sweep horizontally back and forth, processing regular and equidistant decorative horizontal lines on the wall mortar layer.

[0014] Preferably, the truss module is adapted to different interior wall construction floor heights by adding or removing assembly segments, and the top of the truss module is pressed against the top floor slab by jack support, so as to achieve vertical self-locking fixation of the whole machine without drilling; the ratchet and ratchet one-way self-locking component only allows the jack to extend and restricts the jack to retract.

[0015] Preferably, the meshing transmission structure of the first bevel gear and the second bevel gear is housed inside the second transmission assembly sleeve to achieve dust protection for the transmission components.

[0016] Preferably, the spring applies a preload to the movable horizontal crease working head, so that the fixed horizontal crease working head and the movable horizontal crease working head adaptively and elastically conform to the wall surface, adapting to the slight undulations of the wall surface and composite slurries of different consistency.

[0017] Preferably, the anti-collision bar, indicator bar, and telescopic bar constitute a purely mechanical linkage avoidance mechanism without the installation of electronically controlled sensor elements; when the horizontal sliding block moves back, the mechanical linkage structure resets, and the movable horizontal stripe working head re-fits the wall surface.

[0018] Preferably, the composite slurry is made of plain cement slurry, fine sand and construction adhesive. The fixed cross-texturing working head and the movable cross-texturing working head act on the surface of the composite slurry to complete the cross-texturing.

[0019] Preferably, the jack is equipped with an unlocking lever. After construction is completed, moving the unlocking lever will cause the jack to retract, releasing the top support fixation of the entire machine. The truss module can be disassembled for equipment transportation and storage.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Adaptable to indoor construction with varying floor heights, highly versatile: The truss module of this device adopts a segmented assembly structure, which can flexibly add or remove sections according to different indoor room heights. With the bottom jack for fine-tuning the top support, it is suitable for conventional residential indoor construction heights. It is easy to assemble, disassemble, and transport, solving the problem of poor floor height adaptability of traditional equipment.

[0022] 2. High precision in horizontal stripe forming and good texture consistency: Relying on the quantitative stepping control of the first motor and the fixed pitch transmission of the lead screw, the vertical equidistant precise lifting of the working head is realized, replacing manual line laying and alignment, ensuring that the spacing of each horizontal stripe is uniform and the arrangement is neat; with the spring self-adaptive working head structure, it can adapt to different consistencies of cement slurry + fine sand + construction adhesive composite slurry and the slight undulations of the wall surface, forming horizontal stripes with consistent depth and high clarity.

[0023] 3. Fully mechanized operation, eliminating high-altitude hazards: The power components of the whole machine are arranged in a low position, and the equipment is controlled on the ground throughout the process. It automatically completes horizontal sweeping and vertical layer changing operations, completely replacing manual high-altitude scaffolding construction, eliminating high-altitude operation safety hazards, and greatly improving construction efficiency.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 The diagram shows the overall structure of an indoor wall surface horizontal texturing device according to the present invention. The device mainly consists of three parts: a frame top support fixing component, a vertical stepping transmission component, and a horizontal texturing working module 6. The frame top support fixing component includes a sleeve support 2, a jack 201, and a truss module 3. The vertical stepping transmission component includes a first motor 1, a support 102, a first transmission combination sleeve 101, a first transmission crossbar 103, a first bevel gear 104, a second transmission combination sleeve 301, a second bevel gear 401, a transmission upright 4, and a vertical sliding block 5. The horizontal texturing working module 6 is installed on the outside of the vertical sliding block 5 and is used to complete the horizontal texturing operation of the wall surface slurry layer.

[0033] Figure 2This diagram shows the node of a right-angle internal gear transmission, illustrating the bevel gear reversing transmission structure. The first bevel gear 104 and the second bevel gear 401 are arranged inside the closed cavity of the second transmission assembly sleeve 301. They mesh with each other to achieve a 90° reversal of the transmission direction, converting horizontal rotational power into vertical rotational power. Simultaneously, the second transmission assembly sleeve 301 prevents construction mortar and dust from entering the gear meshing pair, avoiding gear jamming. The first bevel gear 104 is assembled at the end of the first transmission crossbar 103, and the second bevel gear 401 is fixedly installed at the bottom end of the transmission upright 4.

[0034] Figure 3 This is a structural diagram of the assembly node of the sleeve support and truss. Truss module 3 is a segmented, modular structure. The number of truss segments can be increased or decreased on-site according to the actual floor height of the rooms to adapt to different interior wall construction heights in residential buildings. Truss module 3 is vertically erected above sleeve support 2. Jack 201 is fixedly installed inside sleeve support 2. The bottom end of jack 201 is fixed to the internal base plate of sleeve support 2, and the top end of jack 201 pushes upward to support the lower end of truss module 3. Jack 201 is equipped with a ratchet and tooth one-way self-locking assembly, which only allows jack 201 to extend upward, preventing jack 201 from retracting due to vibration. When the equipment is in place, extend jack 201 to push truss module 3 upwards until the top of truss module 3 firmly presses against the roof slab. The floor slab, jack, and frame support form a vertical support, allowing the entire machine to achieve self-locking fixation without drilling holes in the wall or floor slab. Jack 201 is equipped with an unlocking lever. After construction is complete, moving the unlocking lever releases the ratchet lock, allowing jack 201 to retract and lower, releasing the supporting force on truss module 3.

[0035] See also Figure 1 and Figure 2 The first motor 1 is fixedly mounted on the support 102, which can be fixedly arranged at a low position on the side of the sleeve support 2, realizing the low-position layout of the power components and facilitating operation by ground personnel. The output end of the first motor 1 is connected to the first transmission combination sleeve 101, which drives the first transmission crossbar 103 to rotate horizontally; the first bevel tooth 104 at the end of the first transmission crossbar 103 engages to drive the second bevel tooth 401 to rotate, thereby driving the transmission upright 4 to rotate within the cavity of the truss module 3. The transmission upright 4 and the vertical sliding block 5 form a threaded screw pair transmission; when the first motor 1 operates at a fixed angle according to the preset horizontal stripe spacing parameters, the transmission upright 4 rotates through the set angle accordingly, driving the vertical sliding block 5 to achieve vertical equidistant step-up and drop along the transmission upright 4, thereby precisely controlling the vertical arrangement spacing of each horizontal stripe.

[0036] Figure 4 , Figure 5These are the node diagram and exploded view of the horizontal stripe working module, respectively. A fixed support block 601 for the horizontal stripe working module 6 is fixedly connected to the outside of the vertical sliding block 5. A second motor 602 is fixedly mounted on the fixed support block 601, and a second transmission crossbar 603 and a guide rod 604 are arranged parallel to it. The second transmission crossbar 603 is driven to rotate by the second motor 602. A horizontal sliding block 610 is simultaneously sleeved on both the second transmission crossbar 603 and the guide rod 604. When the second transmission crossbar 603 rotates, it drives the horizontal sliding block 610 to perform stable horizontal reciprocating sliding along the guide rod 604. A telescopic rod 607 is assembled on the outside of the horizontal sliding block 610, and the outer end of the telescopic rod 607 is connected to the movable horizontal stripe working head 609. The fixed horizontal stripe working head 608 is directly fixed to the outside of the fixed support block 601. A spring 611 is clamped between the fixed horizontal grading head 608 and the movable horizontal grading head 609. The spring 611 continuously outputs elastic preload, which allows the fixed horizontal grading head 608 and the movable horizontal grading head 609 to adapt to the wall surface. This allows them to adapt to the slight unevenness of the wall surface and to be compatible with composite slurries made of cement paste, fine sand and construction adhesive of different consistency, ensuring uniform texture depth during grading.

[0037] Figure 6 This diagram shows the anti-collision structure at the end of the horizontal striped working module, illustrating a purely mechanical end-avoidance mechanism. An anti-collision bar 605 and an indicator bar 606 are installed at the end of the fixed support block 601. The anti-collision bar 605, indicator bar 606, and telescopic bar 607 together form a purely mechanical linkage avoidance mechanism without electronic sensors. When the horizontal stripe working module 6 moves horizontally to the end of the wall following the horizontal sliding block 610, the anti-collision rod 605 first contacts the wall end, corner, and other limiting structures. The anti-collision rod 605 is displaced by the pressure, and the telescopic rod 607 is retracted through the mechanical linkage of the indicator rod 606. The telescopic rod 607 pulls the movable horizontal stripe working head 609 away from the wall surface to prevent the movable horizontal stripe working head 609 from hitting the corner of the wall and avoiding damage to the already formed horizontal stripe texture. When the horizontal sliding block 610 returns to the middle of the wall, the anti-collision rod 605 is released from the wall end limiting constraint, the entire mechanical linkage structure automatically resets, and the movable horizontal stripe working head 609 is back against the wall surface under the action of the spring 611 to continue the stripe sweeping operation.

[0038] The complete construction process of the horizontal ribbed wall installation device in this embodiment is as follows:

[0039] The first step is equipment assembly and fixing: Measure the height of the interior wall to be treated, select the corresponding number of truss modules 3, place the entire machine on the ground at the location of the wall to be treated, and level the ground at the frame support 2; operate the jack 201 to extend upwards and push the truss module 3, so that the top of the truss module 3 presses against the upper floor slab. The jack 201 is locked by the ratchet and ratchet one-way self-locking component, completing the vertical self-locking fixing of the entire machine without drilling. In terms of the overall force, the vertical load is borne by the jack 201, and the impact load generated by the horizontal sweeping operation is transferred to the truss module 3 and borne by the truss module 3. During the reciprocating operation, the entire machine is not prone to slippage or loosening.

[0040] The second step is equipment positioning: Input the design horizontal stripe spacing parameters into the control system, start the first motor 1, and drive the transmission upright 4 to rotate through the first transmission crossbar 103, the first bevel gear 104, and the second bevel gear 401, which in turn raises and lowers the vertical sliding block 5 together with the horizontal stripe working module 6 to the initial construction height.

[0041] The third step is wall pretreatment: a composite decorative slurry made of cement slurry, fine sand and construction adhesive is evenly applied to the plastered wall surface.

[0042] Step 4, horizontal texture forming operation: Start the second motor 602, which drives the second transmission crossbar 603 to rotate, causing the horizontal sliding block 610, the fixed horizontal texture working head 608, and the movable horizontal texture working head 609 to perform horizontal reciprocating motion, uniformly sweeping the surface of the composite slurry to form a single horizontal decorative texture; when the horizontal texture reaches the end of the wall, through Figure 6 The purely mechanical avoidance mechanism shown causes the movable horizontal stripe working head 609 to temporarily detach from the wall surface, and automatically reset and reattach to the wall upon return.

[0043] The fifth step is the vertical layer replacement cycle operation: After completing the processing of one horizontal line, the first motor 1 rotates in a fixed amount, driving the vertical sliding block 5 to move upward at equal intervals to the construction height of the next horizontal line, repeating the horizontal sweeping process; continuously cycling until all horizontal lines on the entire wall surface are processed.

[0044] Step 6, Equipment disassembly and storage: After all construction is completed, move the unlocking lever of jack 201 to release the ratchet lock, control jack 201 to retract and descend, and release the top support of truss module 3 to the floor slab; disassemble the assembled sections of the truss module, clean the equipment, and then transport and store it.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
