Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery equipment, and particularly relates to a road roller capable of providing pedestrian protection. Background Art

[0002] A road roller is a construction machinery used to compact soil, asphalt, gravel or other materials. It is mainly used in road construction, bridge construction, airport runway paving, parking lot construction and various other infrastructure projects. It compacts materials through its own weight and equipped vibration or static pressure devices to achieve the required density and flatness.

[0003] In the past applications of road rollers, especially in densely populated areas in cities, safety accidents such as the road roller accidentally running over pedestrians and flying gravel hurting people have occurred many times. At present, most road rollers in the existing technology do not have corresponding pedestrian protection structures, which pose great safety hazards during the road rolling operation of the road roller. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a road roller capable of providing pedestrian protection for the above problems existing in the prior art.

[0005] In order to achieve the purpose of the utility model, the following technical solutions can be adopted:

[0006] A road roller capable of providing pedestrian protection includes a frame. One end or both ends of the frame are provided with road rolling drums. A protection structure for preventing pedestrians from entering the rolling area from both ends of the road rolling drum and / or the side away from the frame is arranged on the frame through a detachable structure. A flying stone prevention structure for preventing stone splashing is further arranged under the protection structure.

[0007] The road roller of the utility model aims to improve construction safety, especially to protect those who may be close to the operation area of the road roller from being run over by the road rolling drum and injured by flying stones. Among them, the frame is the main body of the road roller, and the road rolling drum is used to specifically compact the road surface, which is the prior art. The protection structure is used to prevent pedestrians or other objects from accidentally entering the rolling area and being injured. The protection structure is arranged on the frame through a detachable structure, which is convenient for disassembly and assembly and flexible in use. The flying stone prevention structure is used to prevent the flying of crushed stones or sundries generated during the compaction process and avoid hurting nearby personnel. The protection structure and the flying stone prevention structure greatly improve the safety of the road roller construction process and the feasibility of operating in densely populated areas.

[0008] In the above road roller capable of providing pedestrian protection, the protection structure includes a front protection frame located in front of the road rolling drum. The front protection frame is vertically arranged, and the length direction thereof is consistent with the axial direction of the road rolling drum. A side protection frame is arranged on the side of the front protection frame.

[0009] The front protective frame is vertically arranged to ensure that people or objects approaching the road roller drum from the front will not directly enter the rolling area. The side protective frames are arranged on the sides, which can further restrict pedestrians or objects from entering the rolling area from the side, achieving all-round safety protection and reducing the possibility of accidents.

[0010] In the road roller capable of providing pedestrian protection as described above, the detachable structure includes two groups of connecting rods respectively arranged on the vehicle frames at both ends of the road roller drum. One end of each connecting rod is fixedly connected to the front protective frame, and the other end is detachably fixed to the vehicle frame by bolts. Each group of connecting rods has at least two.

[0011] Both ends of the front protective frame are detachably fixed to the vehicle frame through connecting rods. Each group of connecting rods has at least two and is not parallel, forming a stable structure similar to a triangle, with high structural strength. The bolt connection method has flexible detachability, and can be quickly installed or removed according to actual needs to adapt to different working environments, and also facilitates subsequent repair and maintenance.

[0012] In the road roller capable of providing pedestrian protection as described above, the connecting rods are parallel to the end face of the road roller drum. The side protective frame is detachably fixed to the outside of the connecting rods by bolts, and the lowest position of the side protective frame is higher than the ground.

[0013] The connecting rods are perpendicular to the axial direction of the road roller drum, which helps to keep the position of the front protective frame stable and also facilitates the setting of the side protective frame. The side protective frame is arranged on the outside of the connecting rods by bolts, which is convenient for disassembly and assembly, and can be easily installed or removed according to needs, providing flexibility for different working scenarios. In addition, the lowest position of the side protective frame is higher than the ground, which can prevent pedestrians or other objects from entering the rolling area from the side without affecting the normal operation of the road roller.

[0014] In the road roller capable of providing pedestrian protection as described above, the anti-flying stone structure includes a protective net arranged under the side protective frame. The upper end of the protective net is fixed to the outside of the side protective frame by bolts, and at least shields the rolling area from the side.

[0015] The protective net is used to prevent stones or other debris from flying out from the side during the rolling process to protect the surrounding people. It is also fixed by bolts for easy disassembly and replacement. As an optimization, the protective net uses a mesh sheet with a certain rigidity but also can be appropriately deformed.

[0016] In the road roller capable of providing pedestrian protection as described above, the anti-flying stone structure includes a number of protective plates arranged under the front protective frame. An elastic mounting component that can elastically lift and lower with the undulation of the ground is provided between the protective plates and the front protective frame.

[0017] The protective plate is used to prevent stones or other debris generated during the rolling process from flying out from the front side. The protective plate is arranged on the front protective frame through an elastic mounting component, so that the protective plate can automatically adjust its height with the undulation of the ground, ensuring that it always maintains an appropriate distance from the ground, neither affecting the normal operation of the roller nor compromising the comprehensiveness of protection.

[0018] In the above-mentioned roller capable of providing pedestrian protection, the elastic mounting component includes mounting blind holes that are evenly distributed along the length direction at the bottom of the front protective frame and are vertically upwardly opened. Telescopic rods are inserted into the mounting blind holes. An elastic member is provided between the upper end of the telescopic rod and the inner top surface of the mounting blind hole, and a universal wheel assembly is provided at the lower end. The protective plate is detachably fixed to the side of the telescopic rod.

[0019] The mounting blind holes are used to install the telescopic rods and elastic members to support and control the movement of the protective plate. The telescopic rods are inserted into the mounting blind holes and can move vertically up and down. The rollers of the universal wheel assembly at the lower end roll on the ground, adapting to the undulation of the ground. The elastic member can be a spring, which provides a downward elastic force to the telescopic rod. Under the combined action of gravity, it ensures that the rollers of the universal wheel assembly always closely adhere to the ground. The protective plate is also fixed to the side of the telescopic rod through a bolt plate, which is convenient for disassembly and assembly and can adapt to different usage scenarios. The universal wheel assembly among them is common knowledge and will not be specifically elaborated.

[0020] In the above-mentioned roller capable of providing pedestrian protection, a limiting boss is provided at the upper end of the telescopic rod. An annular anti-disengagement cover is provided outside the mounting blind hole. The anti-disengagement cover is fixed to the bottom surface of the front protective frame through bolts. The telescopic rod passes through the anti-disengagement cover, and the inner diameter of the anti-disengagement cover is smaller than the outer diameter of the limiting boss.

[0021] The limiting boss and the annular anti-disengagement cover cooperate to prevent the telescopic rod from completely disengaging from the mounting blind hole. The anti-disengagement cover is fixed by bolts and has flexible detachability. The outer diameter of the limiting boss is adapted to the inner diameter of the mounting blind hole, and the outer diameter of the telescopic rod is adapted to the inner diameter of the anti-disengagement cover, which has a good positioning effect on the telescopic rod. As an optimization, the anti-disengagement cover is formed by docking and splicing two semi-circular rings, which is convenient for installation.

[0022] As an optimization, in some scenarios where the universal wheels cannot effectively roll, the telescopic rod can be toggled to the highest position and locked and limited through a locking structure, so that it always remains in a fully retracted state. Even more, the protective plate, telescopic rod, and universal wheel assembly can all be removed to adapt to this application scenario. The locking structure can be formed by opening a locking hole communicating with the mounting blind hole on the outer side of the lower part of the front protective frame. The locking pin is inserted into the locking hole to block the limiting boss above, preventing the telescopic rod from extending downward.

[0023] In the above-mentioned road roller capable of providing pedestrian protection, a square mounting platform is provided at the lower end of the telescopic rod, the universal wheel assembly is arranged on the bottom surface of the mounting platform, the protection plate is fixed to the front side of the mounting platform by bolts, a vertically extending guiding groove is formed through the upper part of the protection plate, a guiding bolt is inserted into the guiding groove, and the guiding bolt is screwed into a threaded hole on the front side of the front protection frame.

[0024] The mounting platform at the lower end of the telescopic rod is used for mounting the universal wheel assembly and the protection plate. Its square shape is particularly convenient for fixing the protection plate on the front side. The protection plate is provided with a guiding groove, and the guiding bolt is slidably limited in the guiding groove. On the one hand, it is beneficial to position the protection plate and keep it in a vertical state. On the other hand, it is used to adapt to the lifting movement of the protection plate. The guiding bolt is screwed onto the front protection frame, which has flexible disassembly and assembly properties.

[0025] In the above-mentioned road roller capable of providing pedestrian protection, vertical ribs and sliding grooves extending vertically are respectively provided on adjacent side surfaces of the protection plate, and the ribs are slidably connected in the sliding grooves.

[0026] Adjacent protection plates are butted through the ribs and sliding grooves. While not affecting the relative lifting movement, it ensures the integrity of the protection surface formed by the protection plates and improves the comprehensiveness of protection.

[0027] As an illustration, many structures in the present utility model adopt bolt fixation. This fixation method is common knowledge, and specific setting details are not specifically elaborated.

[0044] As Figure 1 shown in the figure, the protection structure 2 includes a front protection frame 21 located on the front side of the road roller drum 11. The front protection frame 21 is vertically arranged, and its length direction is consistent with the axial direction of the road roller drum 11. A side protection frame 22 is provided on the side of the front protection frame 21. The detachable structure 23 includes two groups of connecting rods 24 respectively arranged on the frame 1 at both ends of the road roller drum 11. One end of the connecting rod 24 is fixedly connected to the front protection frame 21, and the other end is detachably fixed to the frame 1 through bolts. Each group of connecting rods 24 has two.

In addition, the lowest position of the side guard frame 22 is higher than the ground, which can prevent pedestrians or other objects from entering the rolling area from the side without affecting the normal operation of the road roller.

[0046] As Figure 1 , 3 , as shown in Figure 5, the anti-flying stone structure 3 includes a protective net 31 arranged below the side guard frame 22. The upper end of the protective net 31 is fixed to the outside of the side guard frame 22 through bolts, at least blocking the rolling area from the side. The anti-flying stone structure 3 also includes a number of protective plates 32 arranged below the front guard frame 21. An elastic mounting component 33 that can elastically lift and lower with the ground undulation is provided between the protective plate 32 and the front guard frame 21.

[0047] Specifically, the protective net 31 is used to prevent stones or other debris from flying out from the side during the rolling process and protect the surrounding personnel. It is also installed and fixed through bolts, which is convenient for disassembly, assembly and replacement. As an optimization, the protective net 31 is made of a mesh sheet with a certain rigidity but also capable of appropriate deformation. The protective plate 32 is used to prevent stones or other debris generated during the rolling process from flying out from the front side. The protective plate 32 is arranged on the front guard frame 21 through the elastic mounting component 33, so that the protective plate 32 can automatically adjust its height with the undulation of the ground, ensuring that it always maintains an appropriate distance from the ground, neither affecting the normal operation of the road roller nor compromising the comprehensiveness of the protection.

[0048] As Figure 1 , 2As shown, the elastic mounting assembly includes mounting blind holes 34 evenly distributed along the length direction at the bottom of the front protective frame 21 and vertically opened upward, a telescopic rod 36 is inserted in the mounting blind hole 34, an elastic member 35 is provided between the upper end of the telescopic rod 36 and the inner top surface of the mounting blind hole 34, a universal wheel assembly 37 is provided at the lower end, and a protective plate 32 is detachably fixed on the side of the telescopic rod 36. A limiting boss 38 is provided at the upper end of the telescopic rod 36, and an annular anti-detachment cover 39 is provided on the outer side of the mounting blind hole 34. The anti-detachment cover 39 is fixed to the bottom surface of the front protective frame 21 by bolts, and the telescopic rod 36 is inserted in the anti-detachment cover 39, and the inner diameter of the anti-detachment cover 39 is smaller than the outer diameter of the limiting boss 38. A square mounting platform 40 is provided at the lower end of the telescopic rod 36, and the universal wheel assembly 37 is arranged on the bottom surface of the mounting platform 40. The protective plate 32 is fixed to the front side of the mounting platform 40 by bolts. A vertically extending guide groove 41 is penetrated through the upper part of the protective plate 32, and a guide bolt 42 is passed through the guide groove 41. The guide bolt 42 is screwed to the screw hole on the front side of the front protective frame 21.

[0049] Specifically, the mounting blind hole 34 is used to install the telescopic rod 36 and the elastic member 35 to support and control the movement of the protective plate 32. The telescopic rod 36 is inserted into the mounting blind hole 34 and can move vertically up and down. The roller of the universal wheel assembly 37 at the lower end rolls on the ground and can adapt to the ups and downs of the ground. The elastic member 35 can be a spring to provide downward elastic force to the telescopic rod 36.

[0050] As an optimization of this embodiment, vertically extending ribs and sliding grooves are respectively provided on adjacent side surfaces of the protective plate 32, and the ribs are slidably connected in the sliding grooves.

[0051] Specifically, the adjacent protective plates 32 are butted through convex ribs and chutes, which ensures the integrity of the protective surface formed by the assembled protective plates 32 while not affecting the relative lifting movement, thus improving the comprehensiveness of protection.

[0052] Specific working principle: When the road roller is performing road compaction operations, the front protective frame 21 and the side protective frames 22 surround the road roller drum 11 from the front side and the left and right sides respectively to prevent pedestrians or other objects from entering. During the compaction process, if gravel splashes out from the left and right sides, it is intercepted by the protective net 31, and the flying stones on the front side are intercepted by the protective plates 32. As the road roller moves forward, the universal wheel assembly 37 and the telescopic rod 36 adaptively lift and lower with the undulation of the ground, always forming a comprehensive flying stone protection surface.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
