All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

The embodiment provides a rail vehicle cab hood handling instrument, as shown in fig. 1 to 8, including lifting hook 1, lifting hook 1 includes shank 101 and gib head 102, and gib head 102 is a U shaped plate, and the U shaped plate includes two vertical plate sections and a horizontal plate section, and two vertical plate sections are located the both ends of horizontal plate section perpendicularly, and two vertical plate sections are parallel to each other. One vertical plate section in the U-shaped plate is fixedly connected with one end of the hook body 101, and the other end of the hook body 101 is provided with a hanging hole 103.

Working principle:

After the lifting rope or the hanging strip 2 of the lifting device is connected with the lifting hole 103 of the lifting hook 1, the hook head 102 of the lifting hook 1 is hooked at the top of the front window 7 of the cab hood 4, specifically, the top of the front window 7 is clamped in two vertical plate sections of the U-shaped plate, after the front window 7 is clamped, the lifting rope or the hanging strip 2 is wound by the lifting device, the cab hood 4 is lifted to be vertically suspended, and then the lifting device is driven to move back and forth and left through a moving platform and other mechanisms, so that the cab hood 4 is aligned with the main body structure 2 of the railway vehicle, and the installation can be carried out. The number of the hooks 1 and the positions of the hooks on the front window 7 are set according to actual needs, if only one hook 1 is adopted, the hooks 1 should be hooked on the middle position of the top of the front window 7, and when two hooks 1 are adopted, the two hooks 1 should be respectively positioned on the positions, close to two ends, of the top of the front window 7.

The head cover lifting tool for the cab of the railway vehicle has the following advantages:

① The lifting hook 1 is adopted for lifting, and the cab hood 4 can be hooked with the front window 7 whether the side window exists or not, so that the cab hood 4 is applicable to whether the side window exists or not, and the application range is wider;

② The U-shaped platy hook head 102 is convenient for hooking and unhooking, so that the head cover is more convenient to hoist and operate, and the installation efficiency is improved.

In this embodiment, as shown in fig. 1 to 8, the shank 101 is a straight plate, one end of the straight plate is integrally fixed with one vertical plate segment in the u-shaped plate, and one plate surface (defined as front surface) of the straight plate faces the other vertical plate segment in the u-shaped plate, that is, the plate surface of the straight plate is parallel to the other vertical plate segment in the u-shaped plate, so that the hook 1 is in a J shape as a whole, and reference is made to a side view shown in fig. 7 in detail. The hook body 101 and the hook head 102 are formed by integrally punching and bending tool steel with a certain thickness, and the tool steel has excellent wear resistance and deformation resistance and is particularly suitable for working conditions of production workshops.

In order to improve the bearing capacity of the hook body 101 and avoid bending deformation, in this embodiment, as shown in fig. 1 to 8, two sides of the straight plate are provided with rib plates 104, and the rib plates 104 are bent towards the other plate surface of the straight plate, that is, the side (defined as the back surface) of the straight plate facing away from the vertical plate section of the U-shaped plate away from the hook body 101. The rib plate 104 can improve the structural strength and the deformation resistance of the hook body 101, and the rib plate 104 can be fixed on the hook body 101 in a welding mode.

In order to improve the bearing capacity of the hook 102 and avoid bending deformation, in this embodiment, as shown in fig. 1 to 8, the vertical plate section connected with the straight plate in the u-shaped plate is provided with a reinforcing rib 105, the reinforcing rib 105 extends to the transverse plate section of the u-shaped plate, the reinforcing rib 105 is located on the outer side surface of the u-shaped plate, and the inner side surface of the u-shaped plate is a plane. The reinforcing ribs 105 can improve the structural strength and the deformation resistance of the hook head 102, and the reinforcing ribs 105 can be fixed on the hook head 102 in a welding mode.

Further, in this embodiment, as shown in fig. 1 to 8, the reinforcing rib 105 may also extend to another vertical plate section (not shown), i.e. the outer side of the vertical plate section away from the shank 101.

In this embodiment, as shown in fig. 1 to 8, a chamfer is provided between two vertical plate segments and a transverse plate segment.

Preferably, the strap 2 is a nylon strap. The orifice of the hanging hole 103 is polished smoothly, so that the nylon sling is prevented from being cut by sharp burrs.

Example 2

In order to pursue the attractive appearance of urban rail vehicles, the anti-climbing device 5 is generally wrapped between the cab hood 4 and the main body structure 3, the anti-climbing device 5 is of a steel structure, and is bolted with the main body structure 3 of an aluminum alloy structure through bolts 9. When the mounting bolts of the anti-creep device 5 are in direct contact with the aluminum alloy body end beams 6, the aluminum alloy body end beams 6 deform and the bolts slip when torque is applied. For this reason, it is necessary to design an anti-skid pad to avoid the deformation of the vehicle body and the slipping of the bolts.

For this purpose, the present embodiment provides an anti-rotation backing plate, as shown in fig. 1 to 8, comprising a carbon steel backing plate 8, wherein bolt holes 801 are provided at two ends of the carbon steel backing plate 8, two limiting plates 802 parallel to each other are provided at two sides of the bolt holes 801, and two opposite sides of a nut 10 are exactly clamped by a space between the two limiting plates 802, so that the nut 10 is prevented from rotating. After the bolt 9 passes through the bolt hole 801, the nut 10 is screwed on, and the nut 10 is just sandwiched between the two limiting plates 802, so that the nut 10 is prevented from rotating. Meanwhile, the carbon steel backing plate 8 can prevent the nuts 10 from being in direct contact with the aluminum alloy vehicle body end beam 6, so that deformation of the vehicle body end beam 6 is effectively reduced, slipping of bolts 9 is avoided, and the installation stability of the anti-creep device 5 is improved.

Example 3

The anti-creep device 5 is generally wrapped between the cab head cover 4 and the main structure 3 of the car body, which causes a dilemma that any person who installs the anti-creep device 5 and the cab head cover 4 first causes inconvenience in installing the other party, so that an installation method suitable for such a front-end system is required.

For this reason, the present embodiment provides a method of installing a front end system, and as shown in fig. 1 to 8, the cab hood 4 and the anti-climbing device 5 are collectively referred to as a front end system, and a method of installing both at the same time is invented. The installation steps are as follows:

Step one, placing an anti-climbing device 5 at the front end of a vehicle body (the vehicle body refers to a main vehicle body structure 3 of aluminum alloy or stainless steel and is a bearing structure of all vehicle-mounted systems of the vehicle) through an elevator.

Step two, lifting the cab hood 4 between the anti-climbing device 5 and the vehicle body through a lifting tool in the embodiment 1, and reserving a torque-applying space for installing bolts 9 of the anti-climbing device 5;

Step three, fixing the anti-creep device 5 through a torque wrench, and placing the anti-rotation backing plate in the embodiment 2 at the nut end to realize the installation and the fixation of the anti-creep device 5;

Step four, hoisting the cab hood 4 to a preset installation interface of the car body through a hoisting tool;

Fifthly, connecting and fixing the cab hood 4 on a vehicle body structure by bolts 9;

And step six, disassembling the lifting tool and finishing the site.

The principles and embodiments of the present utility model have been described in detail with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present utility model; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings.
