Technical Field

The utility model relates to a vehicle safety protection technical field, concretely relates to engineering vehicle driver's cabin protection top net.

Background

When the engineering vehicle is dismantled at high altitude and rescued from natural disasters, most of safety threats come from falling objects on the top of a cab, and therefore a better top protection structure is needed to protect the life safety of a driver. At present, a layer of simple protective net is generally arranged at the top of a cab to block falling objects, the structure is too simple, and the protective effect is poor.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a reasonable in structure, engineering vehicle driver's cabin protection top net that protecting effect is good.

The utility model discloses a following technical scheme realizes: engineering vehicle driver's cabin protection top net includes the elastic protection network of locating the top of driver's cabin through the support, the below of protection network still is equipped with polyurethane buffer board and metal guard plate, polyurethane buffer board and metal guard plate activity are located on the support, the bottom of metal guard plate with be equipped with the spring between the top of driver's cabin, the metal guard plate with connect through the connecting rod between the polyurethane buffer board, be equipped with the nut through the external screw thread adaptation on the support, the nut is located the top of polyurethane buffer board.

The support includes four support columns of locating respectively the top four corners of driver's cabin, the four corners one-to-one of protection network just fixes respectively on four the support columns, polyurethane buffer board and metal protection plate cover are established on the support column, the nut connects soon with the adaptation on the support column.

The support column is provided with a plurality of energy-absorbing columns, and the energy-absorbing columns are located between the polyurethane buffer plate and the metal protection plate.

Compared with the prior art, the utility model has the advantages that in work, falling objects are reliably stopped after six energy absorption actions of protective net interception energy absorption, polyurethane plate top bracing energy absorption, connecting rod crushing energy absorption, metal protection plate reverse impact energy absorption, compression energy absorption of a spring and crushing energy absorption of an energy absorption column, the structure is reasonable, the protection effect is good, and the damage of the falling objects to the top of a cab is effectively avoided; furthermore, the protective net, the polyurethane buffer plate 4 and the metal plate which are arranged in a layered manner can be used for reasonably adjusting positions of different falling objects which possibly exist in different use environments, so that the protective effect is ensured, and meanwhile, the loss of easily damaged parts is reduced.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-3, engineering vehicle driver's cabin protection top net includes elastic protection network 3 that locates the top of driver's cabin 2 through support 1, the below of protection network 3 still is equipped with polyurethane buffer board 4 and metal guard plate 5, polyurethane buffer board 4 and metal guard plate 5 activity are located on the support 1, the bottom of metal guard plate 5 with be equipped with spring 6 between the top of driver's cabin 2, metal guard plate 5 with connect through connecting rod 7 between the polyurethane buffer board 4, be equipped with nut 8 through external screw thread adaptation on the support 1, nut 8 is located the top of polyurethane buffer board 4. The protective net 3, the polyurethane buffer plate 4 and the metal protective plate 5 are sequentially arranged from top to bottom, a falling object contacts the protective net 3 with elasticity first, when the protective net 3 is broken through, the kinetic energy of the falling object is absorbed and reduced, then the polyurethane buffer plate 4 is touched, the polyurethane buffer plate 4 is made of rigid plate-shaped materials, when the polyurethane buffer plate 4 is impacted and broken, the kinetic energy further descends, meanwhile, when the falling object impacts the polyurethane buffer plate 4, the polyurethane buffer plate 4 tends to move downwards, and because the spring 6 is in a completely compressed state at the moment, the polyurethane buffer plate 4 is connected with the metal protective plate 5 through the connecting rod 7, the polyurethane buffer plate 4 moves downwards to crush the connecting rod 7, so that when the polyurethane buffer plate 4 moves downwards, the spring 6 releases energy to rebound and supports the metal protective plate 5 to move upwards, and thus, the metal protective plate 5 moves towards the falling object, partial kinetic energy of the falling object can be counteracted, and after the falling object impacts and presses the metal protection plate 5, the spring 6 absorbs energy and contracts, so that the falling is stopped reliably, and the top of the cab 2 cannot be damaged; the nut 8 presses the polyurethane buffer plate 4 downwards, so that the metal protection plate 5 presses the spring 6 to be in a completely compressed state under the action of the connecting rod 7; the bottommost part adopts the metal protection plate 5 to ensure that the falling objects cannot fall to the top of the cab 2 after being stopped, so that the falling objects can be cleaned conveniently after being stopped; furthermore, the protective net 3, the polyurethane buffer plate 4 and the metal plate which are arranged in a layered manner can be used for reasonably adjusting positions of different falling objects which possibly exist in different use environments, so that the protective effect is ensured, and meanwhile, the loss of easily damaged parts is reduced.

Support 1 includes four support columns 9 of locating respectively the top four corners of driver's cabin 2, the four corners one-to-one of protection network 3 just fixes respectively four on the support column 9, polyurethane buffer board 4 and metal protection plate 5 cover are established on the support column 9, nut 8 connects soon with the adaptation on the support column 9. The protective net 3 is fixedly connected to buffer the falling object for the first time, the polyurethane buffer plate 4 moves downwards along the support column 9 under the impact of the falling object, the metal protective plate 5 moves upwards along the support column 9 under the action of energy releasing and rebounding of the spring 6, then moves downwards under the impact of the falling object, and the spring 6 is enabled to be in a compression energy storage state continuously.

The supporting columns 9 are provided with a plurality of energy-absorbing columns 10, and the energy-absorbing columns 10 are located between the polyurethane buffer plate 4 and the metal protection plate 5. When the falling object impacts and pushes the polyurethane buffer plate 4 to move downwards, the polyurethane buffer plate 4 can extrude and damage the energy absorption columns 10, the falling speed of the polyurethane buffer plate 4 is reduced, the falling kinetic energy of the falling object is absorbed, the falling object can be reliably stopped, and the top of the cab 2 is prevented from being damaged; the position of the energy-absorbing column 10 is deviated from the polyurethane buffer plate 4, so that the metal protection plate 5 does not touch the energy-absorbing column 10 when rising, and the waste of the energy-absorbing column 10 is avoided.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
