detailed description

In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings and specific embodiments.

In order to solve the technical problem in the prior art that the labor intensity is high, the efficiency is low, and the environment is bad due to the need for flattening by manual flattening, the present application provides a flat device and a flat armor. Set the flat car.

As shown in FIG. 1, FIG. 2 and FIG. 3, it is a schematic structural view of a flat car with a flat device. The flat car includes a vehicle body 40 and a flat device 50 disposed on the vehicle body 40. In the present embodiment, the number of the flat device 50 is two, which are respectively disposed on opposite sides of the vehicle body 40, and are symmetrically mounted on the vehicle body 40.

The flattening device 50 comprises a flat plow composition 51 and a flat plow composition 53. The flat plow composition 51 is used to flatten the ballast around the rail. The flat plough component 51 is mounted on the vehicle body 40, including a flat plough 511, a first flat plough cylinder 516, a cylinder upper support 512, a fixed guide plate 517, a rocker 514, a rocker support 515, and protection. Cover 518.

The flat plough 511 includes a plough 5112, a wear plate 5111, a cylinder lower support 5113, a movable guide plate 5114, and a fastener 5115. The wear plate 5111 is fixed to the lower end of the pear piece 5112 for flattening. The lower cylinder support 5113 is fixed to the pear piece 5112, and the first flat plough cylinder 516 is installed between the upper cylinder support 512 and the lower cylinder support 5113, and the lifting and lowering of the flat plough 511 is driven by the telescopic expansion. The movable guide plate 5114 is fixed to the pear piece 5111 by a fastener 5115.

The fixed guide plate 517 is fixed to the vehicle body 40, and the movable guide plate 5114 slides inside the fixed guide plate 517 to ensure that the flat plough 511 cannot move to both sides. A shield 518 protects these pairs of motion to prevent accidental injury.

The rocker support 515 is fixed to the vehicle body 40. The rocker 514 is rotatably coupled to the vehicle body 40 at one end, and the plough blade 5112 is rotatably coupled to the other end. The rocker 514 is composed of two upper and lower layers of equal length and parallel to each other, and is a parallel four-bar linkage mechanism, so that the plough 5112 can be kept parallel in the vertical plane, and the lower plane of the plough 5112 is always horizontal. .

The first flat plow cylinder 516 has been equipped with a hydraulic lock to prevent the first flat plow cylinder 516 from being accidentally Outstretched and caused the accidental fall of Pingyi Plough 511.

Further, in order to improve safety and prevent the plough plough 511 from falling accidentally, a locking device 513 is additionally provided, which is mounted on the vehicle body 40. As shown in FIG. 4, the locking device 513 includes a locking tongue 5131, a leaf spring 5132, a leaf spring holder 5133, and a mounting seat 5134. The mounting seat 5134 is fixed to the vehicle body 40. The leaf spring support 5133 fixedly connects the leaf spring 5132 and the mounting seat 5134, and the locking tongue 5131 is fixed to the leaf spring 5132. The leaf spring 5132 plays a role of rebounding and supporting, and the pressing bolt 5131 is embedded in the locking hole on the movable guiding plate 514 to realize the locking of the flat plough 511. The working surface of the locking tongue 5131 is a wedge structure, and the self-weight of the flat plough 511 cannot overcome the frictional force of the wedge structure of the working surface of the locking tongue 5131. Therefore, the flat plough 511 cannot overcome the locking force by its own weight. However, in normal operation, when the external thrust of the first flat plough cylinder 516 is much larger than the frictional force of the wedge structure of the working surface of the bolt 5131, unlocking can be achieved.

When the first flat plow cylinder 516 is retracted, the flat plow 511 gradually rises, and when the movable guiding plate 5114 rises, it slides along the lower working surface of the locking tongue 5131, and overcomes the resilience of the leaf spring 5132, the locking tongue 5131 retreats and exits. The first keyhole. When it rises to the highest point, under the resilience of the leaf spring 5132, the locking tongue 5131 is again embedded in the second locking hole on the movable guiding plate 514, so as to achieve the locking of the flat plough 511.

The flat plow composition 53 has the same structure as the flat plow composition 51. For ease of distinction, the flat plow composition 51 is called a second flat plow cylinder 536.

Referring also to FIG. 5, in the present embodiment, in order to clean the flat track, the flattening device 50 further includes rail cleaners 52 and 54. In the flat plow composition 51, the ballast around the rail is flattened, and the rail cleaner 52 sweeps the ballast at the top of the rail.

The rail cleaner 52 includes a fixing seat 521, a first cleaning cylinder 522, a guide plate 523, and a cleaning Stick 524. The fixing base 521 is fixed on the vehicle body 40. The first cleaning cylinder 522 is mounted between the fixing base 521 and the guiding plate 523. The guiding plate 523 is slidable relative to the fixing base 521, and the cleaning rod 524 is mounted on the sliding plate 523. .

When the first cleaning cylinder 522 is extended, the guiding plate 523 and the cleaning bar 524 are lowered to clean the rail through the cleaning rod 524. When the cleaning is completed, the first cleaning cylinder 522 is retracted, the guiding plate 523 is pulled, and the cleaning is performed. The rod 524 is raised such that the first cleaner cylinder 522 is in an inoperative state.

The structure of the rail cleaner 54 is the same as that of the rail cleaner 52. For ease of distinction, the cylinder of the rail cleaner 54 is referred to as a second cleaner cylinder 542.

Fig. 1 shows the vehicle running to the left side and performing a flattening operation to the left side. At this time, the flat plough composition 53 on the left side and the cleaner 52 on the back side thereof fall. The non-working right end flat plow composition 51 and the left side cleaner 54 on its back are still in a raised state.

Conversely, when the vehicle is running to the right side, the flat side operation is performed to the right side, at this time, the right side plough composition 51 and the left side cleaner 54 at the back thereof will fall. The non-working left plough plough composition 53 and the right side cleaner 52 on its back will be in a raised state.

The existing flat car generally has a single flat plow, and it is really simple to directly operate the hydraulic valve manually. However, the work can only be done in one direction. If it is necessary to make a round trip, the vehicle needs to be turned around, which is troublesome. When it is flat, it is very dusty. Standing on the car and manipulating the body is soil, affecting the health of the operator. This patent adopts two flat ploughs symmetrically installed in front and rear of the vehicle, which can be used for two-way flat boring. When the vehicle goes to and from the flat, there is no need to adjust the head, as long as the flat plough is changed, saving time and material resources. After the remote control is used, the operator can distance a certain distance from the flat plow, and the dust on the flat side has less influence on the operator.
