[0036] This utility model discloses a slewing device and a railway turnout rail welding operation system to solve the technical problem that when a railway turnout rail welding operation vehicle turns, it is necessary to first lay a certain amount of protective material on the track.
[0037] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0038] See Figures 1 to 6 As shown, in one or more embodiments, this application provides a rotating device, which includes: a support 100, a rotating mechanism, a first lifting mechanism, and a lateral telescopic mechanism. The rotating mechanism is mounted on the support 100 and is used to drive the railway turnout welding vehicle 201 to rotate. The first lifting mechanism is used to enable the support 100 to rise and fall along a first direction. The first lifting mechanism is mounted on the lateral telescopic mechanism and is used to enable the first lifting mechanism to move along a second direction, wherein the first direction is perpendicular to the second direction.
[0039] The slewing device provided in at least one embodiment of this application raises and lowers the support 100 through a first lifting mechanism so that the wheels of the railway turnout welding vehicle 201 can be derailed; the lateral telescopic mechanism can extend and retract the first lifting mechanism to provide a more stable support state; and the slewing mechanism drives the railway turnout welding vehicle 201 to rotate, so that the railway turnout welding vehicle 201 can be turned without making certain protective paving on the track.
[0040] In one embodiment, the direction of the railway line extension is referred to as the longitudinal direction, the horizontal direction perpendicular to the railway line extension direction is referred to as the transverse direction, and the direction perpendicular to the horizontal plane is referred to as the vertical direction. When using a rotary device, the first direction is vertical and the second direction is transverse.
[0041] In some embodiments, the lateral telescopic mechanism includes a lateral telescopic device, a first inner guide sleeve 101 and a first outer guide sleeve 102, the first outer guide sleeve 102 being fixedly connected to the bracket 100; the first inner guide sleeve 101 being inserted into the first outer guide sleeve 102, and the lateral telescopic device being used to move the first inner guide sleeve 101 along a second direction; and a first lifting mechanism being mounted on the first inner guide sleeve 101.
[0042] In one embodiment, the first inner guide sleeve 101 has a rectangular cross-section; the first outer guide sleeve 102 has a rectangular cross-section, so that after the first outer guide sleeve 102 is inserted into the first inner guide sleeve 101, the first inner guide sleeve 101 can be prevented from rotating relative to the first outer guide sleeve 102. The number of lateral telescopic mechanisms can be four, so that each lateral telescopic mechanism realizes the movement of a first lifting mechanism in the second direction.
[0043] In some embodiments, the first lifting mechanism includes a first lifting device 103 and a support base 104. The first lifting device 103 is hinged to the support base 104, which is used to contact the ground. In this way, the lifting of the bracket 100 is achieved by the first lifting device 103, and the support base 104 supports the bracket 100.
[0044] In one embodiment, the number of first lifting mechanisms is four, resulting in four support seats 104. This facilitates stable support of the bracket 100, enabling initial lifting of the entire rotating assembly and leveling on elevated sections or uneven ground. Furthermore, the lateral leveling of the entire vehicle can be achieved through the height differences of the different support seats 104.
[0045] In some embodiments, a spherical bearing 105 is further provided between the first lifting device 103 and the support base 104. The first lifting device 103 is fixedly connected to the outer spherical surface of the spherical bearing 105, and the inner spherical surface of the spherical bearing 105 is fixedly connected to a pin 106. The pin 106 is mounted on the support base 104. In this way, the spherical bearing 105 can enable the support base 104 to adapt to a certain angle in the longitudinal direction.
[0046] In some embodiments, the lateral telescopic device is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder; the first lifting device 103 is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.
[0047] In some embodiments, the support 100 includes a first support layer 107 and a second support layer 108, which are connected by a second lifting mechanism. The second lifting mechanism enables the second support layer 108 to move up and down in a first direction. A lateral telescopic mechanism is mounted on the first support layer 107, and a slewing mechanism is mounted on the second support layer 108. By dividing the support 100 into two different layers, the second lifting mechanism can lift the bottom of the railway turnout welding operation to the top of the track 300 under ultra-high working conditions, enabling the smooth turning of the entire vehicle.
[0048] In one embodiment, both the first support layer 107 and the second support layer 108 can be a frame structure, i.e., made of one or more of channel steel, square steel or I-beams.
[0049] In some embodiments, the second lifting mechanism includes a second inner guide sleeve 109, a second outer guide sleeve 110, and a second lifting device 111; the second inner guide sleeve 109 is fixedly connected to the second support layer 108, the second outer guide sleeve 110 is fixedly connected to the first support layer 107, and the second lifting device 111 is hinged to the outer guide sleeve and the second support layer 108 respectively. It should be noted that... Figure 6 The rotary device in the middle has no second lifting mechanism.
[0050] In one embodiment, the second inner guide sleeve 109 has a rectangular cross-section; the second outer guide sleeve 110 has a rectangular cross-section, so that after the second outer guide sleeve 110 and the second inner guide sleeve 109 are inserted, the second inner guide sleeve 109 can be prevented from rotating relative to the first outer guide sleeve 102.
[0051] In some embodiments, the second lifting device 111 is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.
[0052] In some embodiments, the slewing mechanism includes a motor and a slewing bearing. The slewing bearing can be a worm gear type slewing bearing 112, and the motor drives the worm gear type slewing bearing 112 to rotate. The motor is fixed to the second support layer 108. Using a worm gear type slewing bearing 112 has the advantages of compact structure, smooth transmission, and mechanical self-locking. Where space permits, a gear ring speed reduction slewing bearing can also be used, which reduces costs. Of course, in other possible embodiments, manual rotation can be used, or a non-powered slewing bearing can be substituted.
[0053] See Figure 7 and Figure 8As shown, in one or more embodiments, this application also provides a railway turnout rail welding operation system, which includes: a railway turnout rail welding operation vehicle 201, and a slewing device provided in any embodiment; the railway turnout rail welding operation vehicle 201 is mounted on the slewing mechanism. Since this railway turnout rail welding operation system adopts the slewing device in the above embodiments, the beneficial effects of this railway turnout rail welding operation system can be found in the above embodiments.
[0054] In summary, the slewing device and railway turnout rail welding system provided in this application can solve the technical problems of poor rail welding quality and lack of equipment for welding a large number of rail joints on station tracks and turnout lines in related technologies. The slewing device supports the railway turnout rail welding vehicle 201, and the railway turnout rail welding system can be steered through the slewing mechanism integrated at the bottom of the railway turnout rail welding vehicle 201. The slewing requires little space and is flexible.
