Description

Technical Field

[0001] This utility model relates to the field of building coating equipment technology, and in particular to a spray painting equipment for the renovation of old residential areas. Background Technology

[0002] With the advancement of urban renewal, renovation projects for old residential areas are increasing, and exterior wall and ground renovation painting is a common construction step. Currently, these painting operations mostly use mobile painting equipment. This type of equipment typically includes a wheeled vehicle with a high-pressure pump and material hose integrated on it, and the operator uses a handheld spray gun connected to a hose to perform the work.

[0003] However, in actual construction, operators need to hold the spray gun for a long time to spray large areas. This is not only labor-intensive and easy to cause operator fatigue, but also difficult to maintain a stable moving speed and spraying distance after the human body is fatigued. As a result, it is difficult to guarantee the uniformity of the spraying, and quality problems such as paint drips and uneven thickness are likely to occur, affecting the overall aesthetics.

[0004] Furthermore, the outdoor environment of older residential areas is often complex, with uneven ground or slopes being common. Existing mobile spray painting equipment typically only considers movement on flat ground, with a fixed center of gravity. When pushing, pulling, or stationary on slopes, its stability is poor, posing a risk of the equipment sliding or tipping over, which not only affects construction efficiency but also creates safety hazards. In summary, existing spray painting equipment has significant shortcomings in reducing operator workload, ensuring uniform spraying, and maintaining stability in complex sloping environments.

[0005] Therefore, this utility model proposes a painting equipment for the renovation of old residential areas to overcome the shortcomings of the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide a painting equipment for the renovation of old residential areas, which solves the problems of high labor intensity in painting operations, difficulty in ensuring the uniformity of the paint surface, poor stability and safety hazards when operating on complex terrains such as slopes.

[0007] To achieve the above objectives, this utility model provides a painting equipment for the renovation of old residential areas, comprising: a vehicle body, a high-pressure pump body, a feed pipe and a spray gun connection port; as well as a traction mechanism and a counterweight mechanism.

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The first embodiment of this application is as follows: Please refer to Figures 1 to 5 This utility model provides a painting equipment for the renovation of old residential areas, which aims to solve the problems of poor uniformity of spraying in complex terrain, high labor intensity, lack of center of gravity adjustment ability and risk of tipping when operating on slopes.

[0027] like Figures 1 to 5 As shown, the painting equipment for the renovation of old residential areas includes a vehicle body 1, which serves as the mounting base and mobile platform for the entire equipment. A high-pressure pump body 2 is fixedly connected to the vehicle body 1. The high-pressure pump body 2 is equipped with a feed pipe 3 and a spray gun connection port 4 connected to it. The vehicle body 1 is also connected to a traction rod 7 for manually dragging the equipment. The vehicle body 1 is also equipped with a traction mechanism 5 and a counterweight mechanism 6. The traction mechanism 5 is used to clamp and guide the spray gun hose to achieve labor-saving and uniform spraying operations. The counterweight mechanism 6 is used to adjust the center of gravity of the equipment according to the slope of the ground to improve the stability of the equipment when operating on slopes.

[0028] To achieve labor-saving and uniform spraying, one of the core structures of this equipment is the traction mechanism 5. Furthermore, the traction mechanism 5 and the vehicle body 1 form a specific structural fit and connection relationship. Please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 and Figure 4 The structure of the traction mechanism 5 will be described in detail below: The traction mechanism 5 is rotatably connected to the vehicle body 1 via a damping shaft 51. The main body of the traction mechanism 5 includes a hollow outer rod 52 and an inner rod 53 slidably housed inside the outer rod 52. A limiting component 58 for selectively locking or releasing the inner rod 53 is fixedly connected to the end of the outer rod 52. The limiting component 58 includes a fixing box 54, inside which a sliding block 55 is housed. The sliding block 55 is used to interfere with the rod wall of the inner rod 53 to achieve locking. A control rod 582 for driving the sliding block 55 and a limiting block 581 for maintaining the position of the control rod 582 are also movably mounted on the fixing box 54. A spring 57 is also provided inside the fixing box 54. The spring 57 is connected between the sliding block 55 and the connecting post 56 and is used to drive the sliding block when the control rod 582 is released. 55 is reset; a bundled tube assembly 59 for clamping the spray gun hose is also provided on the outer rod 52 or the inner rod 53. The bundled tube assembly 59 includes a fixing block 592, a fixing clamp 591 is installed on the fixing block 592, and a movable clamp 594 that can move relative to the fixing clamp 591 is also provided on the fixing block 592. By rotating the stud 593 that is threadedly engaged with the movable clamp 594, the movable clamp 594 can be driven to move closer to or away from the fixing clamp 591. In the assembled state, the inner rod 53 is slidably engaged with the inside of the outer rod 52, and the limiting component 58 provides locking and releasing control of this sliding relationship. This rotatable, telescopic and lockable guide arm structure ensures that the operator can accurately control the movement trajectory and height of the spray gun hose, thereby ensuring the uniformity of the spraying operation and greatly reducing labor intensity.

[0029] To further improve the equipment's operational stability in complex terrain, the second core structural element of this equipment is the counterweight mechanism 6. Please refer to this section for details. Figure 1 , Figure 3 and Figure 5 The structure of the counterweight mechanism 6 will be described in detail below: The counterweight mechanism 6 includes a fixed frame 61 fixed to the vehicle body 1. The fixed frame 61 has multiple slots 67 distributed along its length. The counterweight mechanism 6 also includes a movable block 62 that can slide along the fixed frame 61. A counterweight block 69 is fixedly connected to the lower part of the movable block 62. The movable block 62 has locking blocks 66 that can selectively engage with the slots 67 to lock the movable block 62 at different positions on the fixed frame 61. To control the movement of the locking blocks 66, the movable block 62 also has a control component 68, which includes controls for operation. The control assembly 68 includes a push block 682 and a pull rod 681 for operation. The push block 682 has a sliding block 63 inside. The push block 682 and the pull rod 681 are linked to the sliding block 63. The sliding block 63 is linked to the locking block 66 through a telescopic column 64. The control assembly 68 also includes a spring 65, which is connected to the sliding block 63 and is used to provide a reset force. When the push block 682 is released, the spring 65 drives the sliding block 63 to reset, and then the locking block 66 is inserted into the locking slot 67 through the telescopic column 64.

[0030] The working principle is as follows: When it is necessary to renovate an old residential area by spraying, the entire equipment is moved to the target location by the traction rod 7, the suction pipe is connected through the feed port 3, and the spray gun hose is connected through the spray gun connection port 4. The high-pressure pump body 2 is started to start the spraying operation. When spraying the wall, first place the spray gun hose between the fixed clamp 591 and the moving clamp 594 of the bundle assembly 59. Rotate the stud 593 to move the moving clamp 594 on the fixed block 592 and clamp the hose, thus connecting the spray gun and the traction mechanism 5 into one unit. The operator pulls the control rod 582 of the limiting assembly 58 to move the sliding block 55 inside the fixed box 54 and keep it in position by the limiting block 581, thereby releasing the lock on the inner rod 53. At this time, under the action of the spring 57 connected to the connecting column 56, the inner rod 53 can be easily pulled to slide inside the outer rod 52 to adjust the spraying height. After adjustment, release the control rod 582, and the sliding block 55 automatically resets and locks the inner rod 53. During spraying, the entire traction mechanism 5 can pitch and rotate horizontally on the damping shaft 51. The operator only needs to guide it lightly to achieve uniform and labor-saving spraying. When the equipment needs to move or operate on a slope, in order to adjust the center of gravity and ensure stability, the operator presses the push block 682 on the control component 68 of the counterweight mechanism 6. The push block 682 drives the sliding block 63 to move through the pull rod 681. The sliding block 63 pulls the locking block 66 through the telescopic column 64, so that the locking block 66 disengages from the slot 67 of the fixed frame 61. At this time, the moving block 62 can be pulled to move the counterweight block 69 along the fixed frame 61 to a new position. After releasing the push block 682, the spring 65 drives the sliding block 63 to reset, so that the locking block 66 is re-embedded in the slot 67 to complete the locking. Through the synergistic effect of the traction mechanism 5 and the counterweight mechanism 6, this utility model effectively solves the problems of high labor intensity, poor uniformity and insufficient stability in complex terrain in the prior art of spraying operations.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
