Description

Technical Field

[0001] This utility model belongs to the field of road roller installation technology, and relates to a road roller for residential roads with high stability due to its stepped support. Background Technology

[0002] With the continuous acceleration of urbanization and the expansion of residential community construction, the construction quality and service life of community roads, as an important infrastructure for residents' daily travel, have received widespread attention. Compared with municipal main roads, community roads are characterized by narrower road width, smaller turning radius, and limited construction space. They also need to meet residents' requirements for road smoothness, noise reduction, and safety. Therefore, more stringent requirements are placed on the adaptability of road construction equipment. As the core equipment for road compaction, the stability of road rollers, the strength of their supporting structures, and the durability of their components directly affect the construction quality and efficiency of community roads.

[0003] Currently, most road rollers used for residential road construction are simplified versions of traditional municipal road rollers. Their structural design does not fully consider the special characteristics of residential construction scenarios, leading to numerous problems in practical applications. Among these problems, the connection stability between the roller assembly and the main body is a key factor affecting construction quality. Existing road roller assemblies are typically connected to the main body via a single connecting frame. The connection between the connecting frame and the roller assembly is often directly fixed with bolts or simply welded, lacking a stepped, reinforced support structure. In residential road construction, road rollers need to frequently turn or operate on uneven roadbeds. The roller assembly is prone to shaking due to uneven stress, which not only causes localized settlement or undulation of the compacted road surface, affecting road smoothness, but may also lead to loose bolts and weld cracks at the connection points due to long-term vibration, shortening the equipment's service life and increasing maintenance costs. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: Currently, most road rollers used for residential road construction are simplified versions of traditional municipal road rollers. Their structural design does not fully consider the specific characteristics of residential construction scenarios, leading to numerous problems in practical applications. Among these, the connection stability between the roller assembly and the main body is a key factor affecting construction quality. Existing road roller assemblies typically connect to the main body via a single connecting frame. The connection between the frame and the roller assembly often uses direct bolt fixing or simple welding, lacking a stepped, reinforced support structure. In residential road construction, the road roller needs to frequently turn or operate on uneven roadbeds. The roller assembly is prone to swaying due to uneven force, which not only causes localized settlement or undulation of the compacted road surface, affecting road smoothness, but also may lead to loose bolts and weld cracks at the connection points due to long-term vibration, shortening the equipment's service life and increasing maintenance costs.

[0005] This utility model describes a stepped support road roller for residential roads with high stability, comprising a road roller body. Connecting frames are installed at both the front and rear ends of the road roller body. Multiple sets of mounting slots are formed on the inner side of each connecting frame. Connecting columns are fixedly connected to the inner side of each mounting slot. A welding column is fixedly connected to the end of each connecting column away from the connecting frame. Welding frames are symmetrically arranged at both ends of the connecting frame. Multiple welding holes are formed on the inner side of each welding frame. The welding columns are inserted into the welding holes and fixedly connected by welding. The ends of two welding frames away from the connecting frame are installed at both ends of the roller assembly of the road roller body.

[0006] The connecting frame has a ventilation hole at the middle of its length.

[0007] The connecting frame is made of high-strength alloy steel.

[0008] The outer surface of the connecting frame is coated with an anti-rust coating, which is an epoxy zinc-rich primer with a thickness of 30-50 micrometers.

[0009] A water tank is provided at the rear end of the road roller body, and an installation structure adapted to the rear mounting frame of the road roller body is provided at the lower end of the water tank.

[0010] A through slot is provided in the middle of the water tank along the vertical direction, and a seat is provided at the upper end of the water tank.

[0011] The water tank is equipped with multiple sets of crisscrossing reinforcing ribs, which are welded and fixed to the inner wall of the water tank, forming a uniform grid structure between the sets of reinforcing ribs.

[0012] The lower end of the seat passes through a slot and is fastened to the mounting bracket at the rear end of the roller body by bolts.

[0013] An oil tank is installed in the middle of the road roller body. The oil outlet of the oil tank is connected to the diesel engine of the road roller body through an oil pipeline. The oil tank is installed at the upper end of the diesel engine of the road roller body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by first aligning the welding frame and the connecting frame, then inserting the welding column, and then welding and fixing it and checking for any repairs, the connection strength and welding efficiency are greatly improved, ensuring the stability of the equipment.

[0015] The water tank's structural design eliminates the need for an additional support frame, allowing for direct installation and saving space. The seat and water tank are stacked vertically without increasing lateral space. The water tank's internal reinforcing ribs strengthen its structure, eliminating the need for thickening the tank walls and avoiding redundant volume. This design satisfies functional requirements while significantly reducing the rear volume, thereby reducing the overall size of the road roller. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] like Figure 1 - Figure 6 As shown, a stepped support road roller for residential roads with high stability includes a road roller body 101. Connecting frames 102 are installed at both the front and rear ends of the road roller body 101. Multiple sets of mounting slots 103 are opened on the inner side of each connecting frame 102. Connecting columns 104 are fixedly connected to the inner side of each mounting slot 103. A welding column 105 is fixedly connected to the end of each connecting column 104 away from the connecting frame 102. Welding frames 106 are symmetrically arranged at both ends of the connecting frame 102. Multiple welding holes 107 are opened on the inner side of each welding frame 106. The welding columns 105 are inserted into the welding holes 107 and fixedly connected by welding. The ends of two welding frames 106 away from the connecting frame 102 are installed at both ends of the roller assembly of the road roller body 101.

[0032] The connecting frame 102 has a vent 201 at the middle of its length direction, through which the internal components of the device are cooled.

[0033] The connecting frame 102 is made of high-strength alloy steel, which has high resistance to pressure and deformation, and can adapt to the complex working conditions during the construction of community roads.

[0034] The outer surface of the connecting frame 102 is coated with an anti-rust coating, which is an epoxy zinc-rich primer with a thickness of 30-50 micrometers, effectively preventing the connecting frame 102 from rusting in a humid environment.

[0035] During operation, the welding frame 106 is symmetrically placed at both ends of the connecting frame 102, so that the welding holes 107 opened on the inner side of the welding frame 106 correspond one-to-one with the positions of the welding column 105.

[0036] Then, slowly insert the welding post 105 into the corresponding welding hole 107. During the insertion process, ensure that there is no obvious gap between the welding post 105 and the welding hole 107 to ensure the stability of the subsequent connection.

[0037] After the welding column 105 is fully inserted into the welding hole 107, the connection between the two is fixed by welding.

[0038] During welding, welding should be applied evenly around the connection between the welding column 105 and the welding hole 107 to ensure welding strength. After welding is completed and cooled, the weld quality should be checked. If there are defects such as porosity or slag inclusion, repair welding should be performed.

[0039] By first aligning the welding frame 106 and the connecting frame 102, then inserting the welding column 105, and finally welding and fixing it, followed by inspection and repair welding, the connection strength and welding efficiency are greatly improved, ensuring the stability of the equipment. Example 2

[0040] like Figure 1 - Figure 8 As shown, a water tank 801 is provided at the rear end of the roller body 101, and an installation structure adapted to the rear end mounting frame of the roller body 101 is provided at the lower end of the water tank 801.

[0041] A through slot 701 is provided in the middle of the water tank 801 along the vertical direction, and a seat 702 is provided at the upper end of the water tank 801.

[0042] The water tank 801 is equipped with multiple sets of crisscrossing reinforcing ribs inside. The reinforcing ribs are welded and fixed to the inner wall of the water tank 801. The sets of reinforcing ribs form a uniform grid structure, which can enhance the overall structural strength of the water tank 801 and prevent the water tank 801 from deforming due to excessive pressure after being filled with water.

[0043] The lower end of the seat 702 passes through the slot 701 and is fastened to the mounting bracket at the rear end of the roller body 101 by bolts.

[0044] When in operation, this installation method can significantly reduce the overall size of the equipment;

[0045] The water tank 801 is directly installed through an installation structure that is compatible with the rear mounting frame of the roller body 101 at the lower end, without the need for an additional support frame, thus saving the space occupied by the frame in traditional installation.

[0046] Meanwhile, the seat 702 is not set up independently next to the water tank 801. Instead, its lower end passes through the slot 701 in the middle of the water tank 801 and is fixed to the mounting bracket. This allows the seat 702 and the water tank 801 to overlap in the vertical direction. The seat 702 does not occupy the lateral space at the rear of the roller body 101, nor does it force the water tank 801 to increase its lateral size to avoid the seat 702.

[0047] Furthermore, the internal structure of the water tank 801 is reinforced with crisscrossing reinforcing ribs, eliminating the need to increase the wall thickness of the water tank 801 to ensure stability and avoiding unnecessary increases in the volume of the water tank 801 itself.

[0048] In this way, while meeting the installation and use requirements of water tank 801 and seat 702, the overall volume occupied by the rear-end components of the road roller is greatly reduced, making the equipment more flexible when constructing on narrow roads in the community and reducing operational obstacles caused by space constraints.

[0049] Example 3

[0050] like Figure 2 As shown, an oil tank 901 is installed in the middle of the roller body 101. The oil outlet of the oil tank 901 is connected to the diesel engine of the roller body 101 through an oil pipeline. The oil tank 901 is installed at the upper end of the diesel engine of the roller body 101.

[0051] During operation, the high-mounted fuel tank 901 allows the fuel to flow more smoothly into the diesel engine through the fuel pipe using its own gravity. This gravity-based fuel supply assists the pressurization device, reducing the possibility of equipment failure and ensuring stable fuel supply. This guarantees that the diesel engine can continuously obtain sufficient fuel during operation, thus ensuring the continuous and efficient operation of the road roller during community road construction.

[0052] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
