Abstract

The utility model relates to the field of support carriers, in particular to a steering and limiting device of a support carrier. Both sides of a front frame of the support carrier are provided with anti-collision blocks, both sides of a rear carrier body of the support carrier are provided with anti-collision plates, and the anti-collision blocks correspond to the anti-collision plates. When a vehicle steers to an extreme position, the anti-collision blocks are in contact with the anti-collision plates. The anti-collision blocks are in face contact with the anti-collision plates, or the anti-collision blocks are in half cylindrical shapes, and the anti-collision blocks are in line contact with the anti-collision plates. The steering and limiting device can play a role of protecting oil cylinders and realizing shock absorption to improve the comfortable feeling of a driver; and as the left side and the right side of a carrier body are both provided with limiting blocks, and the steering and limiting device occupies small space and also can play a role of limitation, the steering and limiting device is very suitable for the support carrier.

Description

A kind of limiting steering device of bracket carrier

Technical field

The utility model relates to the bracket carrier field, is specially a kind of limiting steering device of bracket carrier.

Background technology

At present, the producer of selling bracket carrier at home has Australian worker to create group and institute of Taiyuan coal section, and Australian worker creates group and adopts the oil cylinder automatic spacing in Vehicular turn, and is spacing by the oil cylinder end position in the steering procedure; In addition, it is spacing that institute of Taiyuan coal section bracket carrier employing front vehicle frame framing member bump aftercarriage framing member carries out the limit.

In the prior art, there is a following shortcoming so that upper type is spacing:

Bigger when 1) Australian worker creates group's bracket carrier limit method and redirect to the limit to the oil cylinder damage ratio, reduce oil cylinder service life;

2) it is spacing that institute of Taiyuan coal section bracket carrier adopts car body steel plate bump, and it is big to produce noise, and belongs to rigid impact, and vibrations are big, and bigger to the critical parts damage ratio, crew comfort is poor.

The utility model content

One of the purpose of this utility model is to provide a kind of limiting steering device of bracket carrier, reduces the knockout process noise;

Two of the purpose of this utility model is to provide a kind of limiting steering device of bracket carrier, reduces the infringement to oil cylinder;

Three of the purpose of this utility model is to provide a kind of limiting steering device of bracket carrier, reduces vibrations, improves the crew comfort energy.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of limiting steering device of bracket carrier is provided with anti-collision block in the front vehicle frame both sides of bracket carrier, in the aftercarriage both sides of bracket carrier Crashworthy plate is set, and anti-collision block is corresponding with Crashworthy plate.

The limiting steering device of described bracket carrier, when Vehicular turn arrived end position, anti-collision block contacted with Crashworthy plate.

The limiting steering device of described bracket carrier, anti-collision block is that face contacts with Crashworthy plate.

The limiting steering device of described bracket carrier, anti-collision block is half-cylindrical, anti-collision block is that line contacts with Crashworthy plate.

The limiting steering device of described bracket carrier is at the one-sided employing of the front vehicle frame of bracket carrier two anti-collision blocks up and down, simultaneously at the one-sided employing of the aftercarriage of bracket carrier two Crashworthy plates up and down.

The limiting steering device of described bracket carrier, anti-collision block adopt the anti-collision block of poly-urethane rubber.

The limiting steering device of described bracket carrier, Crashworthy plate adopts the steel plate Crashworthy plate.

Advantage of the present utility model:

1) simple in structure, the low price of the utility model inhibiting device can fully effectively utilize the space;

2) the utility model inhibiting device has higher human oriented design, has reduced the driver's operation fatigue strength;

3) the utility model inhibiting device increases anti-collision block in front vehicle frame, and material adopts poly-urethane rubber, has excellent damping, resiliency, and performance is restored in good incompressible load performance and distortion; In addition, the utility model increases the Crashworthy plate steel plate at aftercarriage, and its material is steel plate B-10/HG785; When Vehicular turn to end position, anti-collision block will carry out face with Crashworthy plate and contact.Thereby, reduce the car load strenuous vibration, critical parts is played a protective role the long parts in court of a feudal ruler service life;

4) the utility model is in the car load steering procedure, increases inhibiting device, by spacing to turning to oil cylinder to play a protective role.

Description of drawings

Fig. 1-Fig. 2 is a structural representation of the present utility model.Wherein, Fig. 1 is a birds-eye view; Fig. 2 is a front view.

Fig. 3 is for adopting the scheme drawing of the utility model Vehicular turn to end position.

Fig. 4 is another embodiment scheme drawing of the utility model.

Fig. 5 is the structural representation of anti-collision block among Fig. 4.

Among the figure, 1 front vehicle frame; 2 anti-collision blocks; 3 turn to oil cylinder; 4 Crashworthy plates; 5 aftercarriages; 6 hinging pin shafts.

The specific embodiment

As shown in Figure 1, the limiting steering device of the utility model bracket carrier by front vehicle frame 1, anti-collision block 2, turn to several parts such as oil cylinder 3, Crashworthy plate 4, aftercarriage 5, hinging pin shaft 6 to form, concrete structure is as follows:

Hinged between front vehicle frame 1 and the aftercarriage 5 by hinging pin shaft 6, simultaneously, turn to the two ends of oil cylinder 3 (two) hinged with front vehicle frame 1 and aftercarriage 5 respectively.In front vehicle frame 1 both sides anti-collision block 2 is set, in aftercarriage 5 both sides Crashworthy plate 4 is set, anti-collision block 2 is corresponding with Crashworthy plate 4.When Vehicular turn arrived end position, anti-collision block 2 contacted with Crashworthy plate 4.

Principle of work of the present utility model is:

Vehicle is in steering procedure is travelled in the down-hole, and car load is when turning to, and direction of passage dish control deflector makes and turns to oil cylinder 3 to stretch, reach and turn to purpose, with hinging pin shaft 6 is that the center is carried out car load and turned to, and the vehicle design steering angle is 45 °, is undertaken spacing by anti-collision block 2.

Anti-collision block 2 is received on the front vehicle frame 1 by four bolts handles, and Crashworthy plate 4 is received on the aftercarriage 5 by four bolts handles.When Vehicular turn arrives end position, the anti-collision block 2 that front vehicle frame 1 increases will carry out face with the Crashworthy plate 4 that aftercarriage increases and contact (100 * 130mm), the force of inertia and the oil cylinder steering effort of car load in turning to can be offset, anti-collision block 2 utilizes poly-urethane rubber to have excellent damping, resiliency, performance is restored in good incompressible load performance and distortion, carry out damping, make chaufeur imperceptible strenuous vibration in steering procedure, can realize limit function.

This kind mode can play the oil cylinder protective effect, can play cushioning effect again, increases the comfort of chaufeur; because all there is limiting stopper the car body left and right sides; and it is very little to take up room, and can play good position-limiting action again, is useful on the bracket carrier very much and uses.

Shown in Fig. 4-5, the utility model can also be at the one-sided employing of front vehicle frame 1 two anti-collision blocks 2, one-sided two Crashworthy plates 4 up and down that also adopt of aftercarriage 5 simultaneously up and down; Anti-collision block 2 is half-cylindrical, and anti-collision block 2 carries out line with Crashworthy plate 4 and contacts.
