DETAILED DESCRIPTION
[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0035] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0036] See also Figure 1-Figure 3 The present application provides a road roller protection device, which includes a crash box 1, at least one articulated seat 2 and at least one articulated telescopic assembly 3.
[0037] One end of the articulated seat 2 is hinged to the anti-collision frame 1, and the other end is connected to the roller body 5; the articulated telescopic assembly 3 includes a telescopic part 32 and an articulated steel section 31 that are hinged to each other, the articulated steel section 31 is connected to the roller body 5, the telescopic part 32 is hinged to the anti-collision frame 1, and the direction of rotation of the anti-collision frame 1 relative to the articulated seat 2 and the articulated steel section 31 includes the walking direction of the roller body 5.
[0038] For example, the number of the articulated seat 2 and the articulated telescopic assembly 3 can be two, so that the protective device can be installed on the roller body more stably. The articulated seat 2 and the articulated steel 31 can be fixed to the roller body 5 by bolts or welded to the roller body 5 to install the protective device on the roller body 5.
[0039] The anti-collision frame 1 is a frame structure, and a person cannot pass through the gap of the anti-collision frame 1. Therefore, after a person hits the anti-collision frame 1, he will not be drawn into the roller body 5 through the gap of the anti-collision frame 1. Since the anti-collision frame 1 is hinged to the hinge seat 2, the anti-collision frame 1 can swing around the hinge seat 2. Since the anti-collision frame 1 is hinged to the hinged steel 31, the anti-collision frame 1 can swing around the hinged steel 31.
[0040] Please see again Figure 2 The protective device can be installed obliquely at the front or rear of the vehicle. Under normal circumstances, under the pulling force of the telescopic member 32, the protective device is a certain distance away from the ground. In this way, the protective device does not affect the normal operation of the roller body 5.
[0041] Please see again Figure 3 When a person hits the anti-collision frame 1, the person will give the anti-collision frame 1 an impact force. Under the action of the impact force and the gravity of the person, the telescopic member 32 extends, and the anti-collision frame 1 rotates around the hinge seat 2 and the hinged steel 31 until the anti-collision frame 1 contacts the ground. The anti-collision frame 1 and the person will move forward with the roller body 5 to prevent the person from being drawn into the roller body 5.
[0042] When a person leaves the anti-collision frame 1, the anti-collision frame 1 is no longer affected by the gravity and impact force of the person, and the telescopic member 32 contracts. Under the action of the telescopic member 32, the anti-collision frame 1 rotates in the opposite direction around the hinge seat 2 and the hinged steel 31 until the anti-collision frame 1 returns to its original position and has a certain distance from the ground.
[0043] Compared with the solution in which a person hits the anti-collision frame 1 and the anti-collision frame 1 does not rotate, in this embodiment, when a person hits the anti-collision frame 1 and the anti-collision frame 1 rotates around the hinge seat 2 and the hinged steel 31, the anti-collision frame 1 can buffer the impact force of the person, thereby greatly reducing the impact force on the person and providing maximum protection for the person.
[0044] Based on the above design, this embodiment arranges an articulated seat 2 and an articulated telescopic assembly 3 between the anti-collision frame 1 and the roller body 5, so that the anti-collision frame 1 can swing relative to the articulated seat 2 and the articulated telescopic assembly 3. When a person collides with the anti-collision frame 1, the anti-collision frame 1 can swing relative to the articulated seat 2 and the articulated telescopic assembly 3 under the impact force, thereby greatly reducing the impact force on the person, and further improving the protective effect of the roller protection device 4 on the person.
[0045] In some embodiments, see Figure 1 and Figure 4 The anti-collision frame 1 includes a first anti-collision frame 11 and a second anti-collision frame 12 which are arranged opposite to each other, and a plurality of connecting rods 14 are connected between the first anti-collision frame 11 and the second anti-collision frame 12; the articulated seat 2 is articulated on the first anti-collision frame 11, and the articulated telescopic assembly 3 is articulated on the second anti-collision frame 12, and the first anti-collision frame 11 is located on a side of the second anti-collision frame 12 close to the roller body 5.
[0046] The anti-collision frame 1 is composed of two layers of anti-collision frames and has a certain thickness, which can more effectively isolate personnel and the roller body 5. In an emergency, it can effectively protect the personnel's arms from being caught in the roller body 5 and being injured.
[0047] In some embodiments, please refer again to Figure 4 The first anti-collision frame 11 includes a first frame body, which is formed by enclosing a plurality of first frame rods 111 . The first anti-collision frame 11 also includes a plurality of anti-collision rods 112 connected between the first frame rods 111 .
[0048] Multiple first frame rods 111 can be integrally formed, and the anti-collision rods 112 and the first frame body can also be integrally formed. Multiple anti-collision rods 112 are staggered on the first frame body. On the one hand, the gap in the first frame body can be reduced, and on the other hand, the strength of the first frame body can be increased, thereby increasing the strength of the anti-collision frame 1, making it difficult for people to pass through the first frame body and be drawn into the roller body 5, and ultimately the protective effect of the protection device on people can be further improved.
[0049] In some embodiments, see Figure 4 and Figure 5 The anti-collision frame 1 also includes an extension rod 13 integrally formed with the first frame body, the hinge seat 2 is hinged to the extension rod 13, the hinge seat 2 includes a seat body 21 and a first hinge plate 22 integrally formed with the seat body 21, and the extension rod 13 and the first hinge plate 22 are hinged through a first hinge shaft 23.
[0050] The first hinge shaft 23 is a conventional hinge shaft, there are two first hinge plates 22, the extension rod 13 extends between the two first hinge plates 22, hinge holes are provided at positions corresponding to the two first hinge plates 22 and the extension rod 13, and the first hinge shaft 23 passes through the hinge holes on the first hinge plates 22 and the extension rod 13 in sequence. In this way, the anti-collision frame 1 can be more easily rotated around the first hinge shaft 23.
[0051] In some embodiments, see Figure 4 and Figure 6 The second anti-collision frame 12 includes a second frame body, which is formed by enclosing a plurality of second frame rods 121 , and a protective net 6 is connected between the plurality of second frame rods 121 .
[0052] The plurality of second frame rods 121 can be integrally formed in sequence, and the protective net 6 can be connected to the second frame rods 121 by a connecting rope, and the protective net 6 can reduce the gap of the second frame. When a person hits the protective net 6, the protective net 6 can further reduce the impact force on the person, thereby better protecting the person, and further improving the protective effect of the protective device.
[0053] In some embodiments, see Figure 6 and Figure 7 The telescopic member 32 includes a single-acting cylinder 321 or a telescopic spring, an extension piece 15 is integrally formed on the second frame, and the piston rod of the single-acting cylinder 321 or the telescopic spring is hinged to the extension piece 15 through a second hinge shaft 322; the articulated steel section 31 includes a steel section body 311 and a second hinge plate 312 integrally formed with the steel section body 311, and the second hinge plate 312 is hinged to the single-acting cylinder 321 or the telescopic spring through a third hinge shaft 313.
[0054] Both the single-acting cylinder 321 and the telescopic spring are conventional products, and their working principles and installation methods are also known to those skilled in the art. Both ends of the single-acting cylinder 321 and the telescopic spring can be connected to two hinged joints, and the extension piece 15 can be hinged to the hinged joints at one end of the single-acting cylinder 321 and the telescopic spring through the second hinge shaft 322. There are two second hinge plates 312, and the hinged joints at the other end of the single-acting cylinder 321 and the telescopic spring extend between the two second hinge plates 312. Hinge holes are provided at positions corresponding to the two second hinge plates 312 and the hinged joints, and the third hinge shaft 313 passes through the hinge holes on the second hinge plates 312 and the hinged joints in turn. In this way, the anti-collision frame 1 can be more easily rotated around the second hinge shaft 322 and the third hinge shaft 313.
[0055] When the telescopic member 32 is a telescopic spring, in a normal state, the telescopic spring is stretched, and the telescopic spring pulls the crash frame 1, so that the crash frame 1 is a certain distance from the ground. When a person hits the crash frame 1, the telescopic spring is further stretched, and the crash frame 1 rotates around the hinge seat 2 and the hinged steel 31 until the crash frame 1 contacts the ground. When the person does not act on the crash frame 1, the telescopic spring returns to its original state, and the crash frame 1 rotates in the opposite direction around the hinge seat 2 and the hinged steel 31 until the crash frame 1 leaves the ground.
[0056] When the telescopic member 32 is a single-acting cylinder 321, under normal conditions, the spring in the single-acting cylinder 321 is compressed, and the single-acting cylinder 321 pulls the crash frame 1, so that the crash frame 1 is a certain distance from the ground. When a person hits the crash frame 1, the spring in the single-acting cylinder 321 is further compressed, the single-acting cylinder 321 extends, and the crash frame 1 rotates around the hinge seat 2 and the hinged steel 31 until the crash frame 1 contacts the ground. When the person does not act on the crash frame 1, the spring in the single-acting cylinder 321 returns to its original state, the single-acting cylinder 321 contracts, and the crash frame 1 rotates in the opposite direction around the hinge seat 2 and the hinged steel 31 until the crash frame 1 leaves the ground.
[0057] like Figure 6 and Figure 7 As shown, in this embodiment, the telescopic member 32 includes a single-acting cylinder 321. The single-acting cylinder 321 can be disassembled, or the pin can be turned upward after being disassembled, which will not affect the rolling operation of the roller body 5 at the joint of the roadbed and the road surface.
[0058] In some embodiments, the cylinder again refers to Figure 6 At least one roller 7 is installed on the side of the anti-collision frame 1 close to the ground.
[0059] For example, the number of rollers 7 can be two, see again Figure 3 When a person hits the anti-collision frame 1, the anti-collision frame 1 contacts the ground, and the roller 7 contacts the ground. When the roller body 5 pushes the anti-collision frame 1 to move, the roller 7 starts to roll, and there is rolling friction between the anti-collision frame 1 and the ground. In this way, not only can the wear caused by the direct contact between the anti-collision frame 1 and the ground be reduced, but also the protective effect of the protective device can be improved.
[0060] In some embodiments, the protection device further includes a proximity sensor and an audible and visual alarm electrically connected to the proximity sensor.
[0061] The proximity sensor and the sound and light alarm are conventional products, and their circuit connection, installation method and working principle are known to those skilled in the art. When the proximity sensor detects that the anti-collision frame 1 is in contact with the ground, the grounding sensor will trigger the sound and light alarm to alert the driver to brake in time, thereby further reducing the harm to personnel and further improving the protective effect of the protection device.
[0062] In summary, the present application arranges an articulated seat 2 and an articulated telescopic assembly 3 between the anti-collision frame 1 and the roller body 5, so that the anti-collision frame 1 can swing relative to the articulated seat 2 and the articulated telescopic assembly 3. When a person collides with the anti-collision frame 1, the anti-collision frame 1 can swing relative to the articulated seat 2 and the articulated telescopic assembly 3 under the impact force, thereby greatly reducing the impact force on the person, and further improving the protective effect of the roller protection device 4 on the person.
[0063] In some embodiments, the present application further provides a roller, which includes the roller protection device 4 of the present application. Since the roller includes the roller protection device 4 of the present application, the roller has all the beneficial effects of the roller protection device 4 of the present application, which will not be repeated here.
[0064] The above are only various implementations of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
