Description

FIELD OF THE INVENTION

The present invention relates to a swivel device for a car cab.

State of the art

As a rule, a cab on a working machine contains several racks and cross members connected together and mounted on a platform for supporting the cab. In order to ensure the safety of the operator of the working machine, a rollover protection device (UZOO) should be provided in the cab structure. UZOO in the design of some cabs uses swivel devices to install the cab on the platform.

The swivel device, as a rule, contains a hinge connector with a hinge hole and a hinge base on which the hinge pin is fixed. When the device is assembled, the pivot pin passes through the pivot hole and is secured to the pivot base so as to provide a pivot joint. Alternatively, the hinge pin may be secured to the hinge connector, while the hinge holes are configured on the hinge base to extend the hinge pin. Such a swivel device can be used in many cases, such as the connection between the cab of the machine and the platform.

A cab that uses a swivel device is suitable for lateral load resistance, i.e. load in the direction transverse to the direction of rotation, but not strong enough to resist the longitudinal load, i.e. load in the direction of rotation. In extreme circumstances, such as tipping over, a strong longitudinal load is applied to the cab and thus the cab tends to deform in the longitudinal direction because the strut can rotate in the longitudinal direction around the hinge base without any restrictions.

Disclosure of invention

In accordance with a first aspect of the present invention, there is provided a rotary-brake articulated device comprising an articulated connector and an articulated base, wherein the articulated connector is articulated to the articulated base, as well as at least one thrust member located on at least one articulated the connector, and the hinge base, but next to each other in order to inhibit the rotation of the hinge connector relative to the hinge base, in at least one direction.

In accordance with a second aspect of the present invention, there is provided a machine cabin mounted on a platform by means of a swivel-swivel device in accordance with the first aspect of the present invention, in which the hinge connector is connected to the cab strut and the hinge base is connected to the platform.

The implementation of the invention

As shown in FIG. 1, the swivel-brake swivel device 100 in accordance with the present invention comprises a swivel connector 10 and a swivel base 20. The swivel connector 10 is connected to the strut 4 of the machine cab and allows the bolt-shaped swivel 22 to pass through the hole 12 as well as the possibility of rotation in the longitudinal direction. The hinge base 20 comprises a right support bar 24 (front, rear, left and right directions as indicated by arrows A, B, C and D respectively in the drawings), a left support bar 26 and a support plate 28. The support plate 28 is mounted on a platform (not shown ) by screwing. The pivot pin 22 is fixed to the supporting bars 24 and 26 of the pivot base 20.

In the first embodiment of the present invention shown in FIG. 1, a stop element in the form of a stop 15 is attached to the front side of the hinge connector 10, while another stop element in the form of a support 25 is located on the front side of the hinge base 20. The stop 15 can be integral with hinge connector 10. Or it can be connected to the hinge connector 10 by welding. The backup 25 can be connected to the hinged base 20 by welding.

Figure 2 shows a schematic view of a first embodiment of a device 100 swivel-swivel joint assembly. As shown in FIG. 2, when the hinge connector 10 is mounted on the hinge base 20, the support 25 is located under the stop 15 and the stop 15 is vertically adjacent to the support 25 connected to the hinge base 20. Thus, when the hinge connector 10 begins to rotate relative to the hinge the base 20, the stop 15 and the support 25 abut against each other so as to slow down the rotation. As shown in figure 2, when the device is manufactured, for ease of assembly, a small gap can be left between the support 25 and the stop 15.

The stop elements, such as the stop 15 and the support 25 according to the present invention, can be located on the front side of the swivel device 100. Thrust elements can also be located on the rear side or can be located on the front and rear sides of the device to prevent rotation both forward and backward.

As one embodiment of the stop element shown in FIG. 1, the support 25 on the hinge base 20 may be located in front of the stop 15 (not shown) so that the stop 15 is longitudinally adjacent to the support 25 on the hinge base 20. Thus , rotation can also be inhibited.

As a rule, the backup is made in the form of a cube. One of the options for the backup in a stepped form is shown in figure 3. In contrast to the backup shown in figures 1 and 2, the backup 25 'is made with a step 25'a. When the hinge connector 10 is mounted on the hinge base 20, the stop 15 is fitted to the step 25'a. When the hinge connector starts to rotate relative to the hinge base 20, the stop 15, fitted to the step 25'a, abuts against the support 25 'so as to inhibit rotation.

In another embodiment of the present invention shown in FIG. 1, the abutment 15 may be removed. As shown in FIG. 4, the support 25 connected to the hinge base 20 is longitudinally adjacent to the hinge connector 10 and the support 25 is higher than the axis of rotation, i.e. the axis of the hinge pin 22. When the hinge connector 10 begins to rotate relative to the hinge base 20, the support 25 abuts against the hinge connector 10 to inhibit rotation. If the support 25 is lower than the axis of rotation, the rotation cannot be effectively braked because the hinge connector 10 can abut against the support 25 after turning a significant angle.

In another embodiment of the present invention shown in FIG. 1, the backup 25 can be removed. As shown in FIG. 5, the stop 15 ′ connected to the hinge connector 10 is vertically located adjacent to the base plate 28 of the hinge base 20. When the hinge connector 10 starts to rotate relative to the hinge base 20, the stop 15 ′ abuts against the base plate 28 to slow down the rotation.

As shown in Fig.6, the stop element is made in the form of a stop 15 ″ located on the right side of the hinge connector 10. The stop 15 ″ can also be located on the left side of the hinge connector 10. After assembling the device, the stop 15 ″ in the vertical direction located next to the support plate 24 of the hinge base 20. In these circumstances, the support plate 24 is used as a backup 25. When the hinge connector 10 begins to rotate relative to the hinge base 20, the stop 15 '' abuts against the support plate 24, h Oba inhibit rotation.

It should be noted that a stop 15 ″ in the vertical direction next to the support bars 24 and 26 can be provided on both the right and left sides of the hinge connector 10 in order to increase rotation braking performance. The stop 15 '' can be located in an intermediate position on the side of the hinge connector, as shown in Fig.6 so as to simultaneously slow down the rotation and forward and backward. If the stop 15 '' is located at one end of the front or rear on the side of the hinge connector 10, only rotation towards that end can be inhibited. If two 15 '' stops are provided at both ends on the side of the hinge connector 10, rotation both forward and backward can also be braked at the same time.

7 shows another preferred embodiment of the present invention, in which the thrust element includes a hinge connector 10 'with a flat base instead of a stop and / or backup. After assembly, the hinge connector 10 'is pivotally connected to the hinge base 20 by the pivot pin 22, and the base of the hinge connector 10' is parallel and vertically adjacent to the base plate 28. When the hinge connector 10 'starts to rotate relative to the hinge base 20, the hinge connector 10 'abuts against the base plate 28 to inhibit rotation.

On Fig shows the cab of the machine, which uses the device 100 of the rotary brake swivel. Four cab racks 4 are connected to a platform (not shown) by a swivel-brake device 100 in which stepped supports 25 'are used in two rear articulated devices 100 and cubic supports 25 are used in two front articulated devices 100. When a running machine is tipped over, a strong longitudinal load is applied to the cab. Therefore, the cabin can be deformed forward, which tends to cause the struts 4 to turn forward. However, since the swivel device 100 in accordance with the present invention can inhibit rotation, the resistance of the cab, i.e. the ability to prevent rollovers is enhanced.

Although the present invention has been described with respect to an example of a swivel device for mounting a machine cabin on a platform, those skilled in the art will recognize that this can also be applied to other areas of technology in which rotation restriction is required, and variations and modifications are made. can be made without departure from the essence and scope of the patented invention, which are defined by the attached claims.

The swivel-brake swivel device disclosed by the present invention can be applied, for example, to the connection of a machine cabin and a platform. Each strut of the cab is connected to the hinge connector of the swivel device, while each swivel base of the swivel device is mounted on a platform for moving the cab. When the stand begins to rotate due to excessive load on the cab, the swivel device will work to slow down the rotation. Therefore, the deformation of the cab of the machine with the load is difficult, and the operator inside the cab remains safe.
