Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, specifically to a device for preventing manholes from falling during municipal road construction. Background Technology

[0002] Municipal roads refer to urban public roads that are invested in, constructed, and managed by the government, located within urban planning areas, and used by the public and vehicles, possessing certain technical standards and facilities. They are an important component of urban infrastructure, undertaking multiple functions such as traffic flow, laying municipal pipelines, and providing public space services. Inspection wells on municipal roads are well-shaped structures within urban underground infrastructure, installed for the inspection, cleaning, dredging, and maintenance of pipeline systems. They are typically located at pipe intersections, bends, changes in pipe diameter or slope, drop structures, and at regular intervals along straight pipe sections.

[0003] During the construction of municipal roads, manholes require fall arrest devices to protect the manhole openings and prevent accidents to pedestrians and vehicles. However, some existing fall arrest devices use a protective net to protect the manhole opening. When a falling object or pedestrian generates a large impact, the protective net may break, resulting in poor manhole protection performance and low safety. Utility Model Content

[0004] The purpose of this utility model is to provide a device to prevent manholes from falling during municipal road construction, so as to solve the problem that some fall prevention devices have poor protective performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device to prevent manhole falls during municipal road construction, comprising a protective cover, and further comprising:

[0006] A connecting frame is provided at the bottom of the protective cover, and a protective net is fixedly connected inside the connecting frame;

[0007] A buffer assembly is disposed at the bottom of the protective cover. The buffer assembly includes a buffer plate disposed at the bottom of the protective cover, a connecting strip disposed at the top of the buffer plate, coarse particles disposed at the top of the protective cover, and a damper disposed at the top of the buffer plate.

[0008] Preferably, the bottom of the protective cover is provided with a bottom rod, and a guide tube is slidably connected to the outside of the bottom rod.

[0009] Preferably, a first spring is welded to the bottom of the base rod, the bottom of the first spring is welded to the bottom of the inner cavity of the guide tube, and a second spring is welded to the bottom of the connecting strip.

[0010] Preferably, a top tube is welded to the bottom of the second spring, and a connecting rod is rotatably connected to the outside of the connecting strip.

[0011] Preferably, the end of the connecting rod away from the connecting bar is rotatably connected to a connecting seat, a third spring is welded to one side of the connecting seat, and the end of the third spring away from the connecting seat is welded to one side of the damper.

[0012] Preferably, a connecting block is fixedly connected to the outer side of the connecting frame, and an adjusting tube is rotatably connected to one side of the connecting block.

[0013] Preferably, the adjusting tube is internally threaded with an installation rod, and the top of the protective cover is provided with a reflective strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a buffer assembly. When the protective cover is subjected to significant pressure, it deforms to a certain extent, thereby applying pressure to the connecting strip. Under this pressure, the connecting strip slides inside the top tube, simultaneously moving the connecting rod on its outer side. This movement of the connecting rod then moves the connecting seat. A guide plate is fixedly connected to the top of the buffer plate, with one side of its inner wall fixedly connected to one side of the damper. The outer side of the connecting seat slides within the guide plate, allowing the connecting seat to move within the guide plate. This movement applies pressure to the third spring, which is then transmitted to the damper. The damper weakens this transmitted pressure, thus reducing the pressure on the buffer plate. When the buffer plate deforms under pressure, it applies pressure to the bottom protective net, which then weakens and absorbs any remaining impact force. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-5 As shown, a manhole anti-fall device during municipal road construction includes a protective cover 1. By setting the protective cover 1, the manhole can be initially covered and protected. It also includes a connecting frame 2 set at the bottom of the protective cover 1. The connecting frame 2 facilitates the installation of the protective net 3 by workers, so that the protective net 3 can be tightly connected to the manhole wall. The protective net 3 is fixedly connected inside the connecting frame 2. Under the action of the protective net 3, the pressure transmitted through the buffer plate 401 is transmitted to the protective net 3, and the residual pressure can be further weakened under the action of the protective net 3.

[0024] The buffer assembly 4, under its function, can block debris and other objects that accidentally enter the inspection well from the outside, and weaken the impact force of falling objects. It is set at the bottom of the protective cover 1. The buffer assembly 4 includes a buffer plate 401 set at the bottom of the protective cover 1. Under the function of the buffer plate 401, the connecting bar 402 can move. At the same time, the pressure on the protective cover 1 can be transmitted to the interior of the buffer plate 401 through the connecting bar 402. The top of the buffer plate 401 is provided with the connecting bar 402, and the top of the protective cover 1 is provided with coarse particles 403. Under the function of the coarse particles 403, pedestrians passing over the inspection well can be warned and pedestrians can be prevented from slipping accidentally. The top of the buffer plate 401 is provided with a damper 404. When the connecting bar 402 moves, it can drive the connecting seat 11 to move through the connecting rod 10, thereby transmitting the pressure it bears to the damper 404. Under the function of the damper 404, the pressure on the buffer plate 401 can be weakened.

[0025] refer to Figure 2 , Figure 3 and Figure 5As shown, a bottom rod 5 is provided at the bottom of the protective cover 1. A guide tube 6 is slidably connected to the outside of the bottom rod 5. A reinforcing plate is fixedly connected inside the protective cover 1. The bottom of the reinforcing plate contacts the top of the bottom rod 5 and the bottom of the reinforcing plate contacts the top of the connecting strip 402, thereby transmitting the pressure borne by the protective cover 1. A first spring 7 is welded to the bottom of the bottom rod 5. When the bottom rod 5 slides inside the guide tube 6 under a certain pressure, it can compress the first spring 7. Under the action of multiple first springs 7 and second springs 8, the protective cover 1 can be reset when it is deformed. The bottom of the first spring 7 is welded to the bottom of the inner cavity of the guide tube 6. A second spring 8 is welded to the bottom of the connecting strip 402. A top tube 9 is welded to the bottom of the second spring 8. A connecting rod 10 is rotatably connected to the outside of the connecting strip 402. When the connecting strip 402 tends to move, it can drive the connecting rod 10 to move.

[0026] refer to Figure 2 and Figure 4 As shown, the end of the connecting rod 10 furthest from the connecting bar 402 is rotatably connected to a connecting seat 11. When the connecting rod 10 moves, it can drive the connecting seat 11 to move, thereby compressing the third spring 12. The third spring 12 is welded to one side of the connecting seat 11. Under the elastic force of the third spring 12, the connecting seat 11 can be reset, allowing the connecting seat 11 and the connecting rod 10 to move to a designated position. The end of the third spring 12 furthest from the connecting seat 11 is welded to one side of the damper 404. Under the action of the damper 404, the pressure transmitted by the third spring 12 can be weakened and absorbed, thereby reducing the pressure on the buffer plate 401. A connecting block 13 is fixedly connected to the outside of the connecting frame 2. One side of the protective cover 3 is rotatably connected to an adjusting pipe 14. Under the action of the adjusting pipe 14, the operator can rotate the adjusting pipe 14 and the mounting rod 15 can move. Thus, when installing this device, the operator can adjust the position of the mounting rod 15 by rotating the adjusting pipe 14, so that the device can be installed and positioned for inspection wells of different sizes. The adjusting pipe 14 is internally threaded with the mounting rod 15. Under the action of the mounting rod 15, the installation position of the protective net 3 can be positioned. At the same time, the operator can adjust the position of the mounting rod 15 to install the protective net 3 inside inspection wells of different sizes. The top of the protective cover 1 is provided with a reflective strip 16. Under the action of the reflective strip 16, the visibility of the protective cover 1 at night can be increased.

[0027] Working principle: When workers use this device to prevent falls through manholes, they first rotate the adjusting pipes 14 according to the size of the manhole. The adjusting pipes 14 move the mounting rods 15, which then move to their designated positions. The workers then position and fix the mounting rods 15 using positioning bolts or welding. Next, the protective cover 1 is placed on top of the buffer plate 401 at the designated position. When the protective cover 1 deforms under pressure, it moves the connecting strip 402, which in turn moves the... The connecting rod 10 on the outside moves, which in turn moves the connecting seat 11, thereby compressing the second spring 8. This transmits the pressure on the connecting bar 402 to the damper 404. Under the action of the damper 404, the pressure on the buffer plate 401 is weakened. At the same time, the pressure transmitted through the buffer plate 401 is weakened and transmitted to the protective net 3. Under the action of the protective net 3, the impact force generated by the falling object is weakened again, thus enabling the device to protect against falling objects or pedestrians.
