Multiple braking devices are configured on the single rail hoist train to ensure the running safety of the locomotive. Some braking devices are arranged on the driving part and the cab, and there is also a single rail hoist with a single braking trolley configured in front of and behind the personnel carrier.

[0003] The braking spring of the existing braking device is arranged below the rail and perpendicular to the rail, and includes a braking oil cylinder with spring reset, a braking plate connected to the braking oil cylinder. The middle of the braking plate is hinged on the vehicle frame, and the other end of the braking plate is connected to a slide bar. The actions of two slide bars are controlled by the action of a single braking oil cylinder, and the braking block is pushed by the slide bar to brake the rail web.

[0015] The present utility model also discloses a single-rail crane configured with the above-mentioned braking and load-bearing trolley. By configuring this braking and load-bearing trolley, the overall safety performance is greatly improved.

[0016] The beneficial effects of the present utility model: A braking device is arranged on the load-bearing and braking trolley, eliminating the need to configure a dedicated braking trolley, which can reduce the length of the entire train of the single-rail crane; by arranging the driving members of the braking device on both sides of the vehicle frame of the load-bearing trolley instead of at the bottom of the load-bearing trolley, the installation method of the braking and load-bearing trolley is the same as that of a common load-bearing trolley, without interference with other components, improving the universality of the structure.

[0023] Refer to Figure 1 and Figure 2 , this embodiment provides a braking and carrying trolley, which includes a frame 5. A channel for the I-beam track 10 to pass through is formed in the middle of the frame 5. Two sets of traveling wheels 8 are arranged on the frame 5, and the traveling wheels 8 run on the lower wing plates on both sides of the web of the I-beam track 10. A connecting seat hinged to the single-track crane component is arranged at the bottom of the frame 5.

[0024] In some possible embodiments, bushings 4 are respectively arranged on the two side plates of the frame 5, and slide bars 12 are arranged in the bushings 4. One end of each slide bar 12 is connected to a brake block 6, and the two brake blocks 6 press against the web of the I-beam track 10 under the action of their respective slide bars 12, thereby realizing braking.

[0025] Furthermore, driving components are arranged on both sides of the frame 5. The driving components are used to drive the slide bars 12 to move in the direction perpendicular to the web of the I-beam track 10. The tail ends of the driving components are connected to the side plates of the frame 5. The drive connector 2 of the driving component is connected to one end of the connecting rod 3, and the other end of the connecting rod 3 is connected to the connector of the slide bar 12. When the driving component expands and contracts, it pushes the connecting rod 3 to rotate around the axis of its first hinge shaft 11, thereby driving the slide bar 12 to move in the bushing 4 in the direction perpendicular to the web of the I-beam track 10, and then realizing releasing the brake or applying the brake.

[0026] In a possible embodiment, the driving member is a brake cylinder 1, which is a brake oil cylinder with spring return. When the brake cylinder 1 is depressurized, the connecting rod member 3 is driven to rotate by the spring force to realize braking. When the brake oil cylinder 1 is filled with oil, the spring is compressed and the connecting rod member 3 is driven to rotate in the opposite direction, thereby realizing brake release.

[0027] In other embodiments, the driving member is arranged as a cylinder with spring return.

[0028] In some embodiments, fixing seats 9 are respectively arranged on both side plates of the vehicle frame 5, and the tail end of the driving member is connected to the fixing seat 9.

[0029] In some possible implementation manners, a second hinge shaft is arranged on the driving connection head 2, a third hinge shaft is arranged on the connection head of the sliding rod 12, a first hinge shaft 11 is arranged on the fixing plate 7 connected to the side plate of the vehicle frame, one end of the connecting rod member 3 is hinged to the second hinge shaft, the other end is hinged to the third hinge shaft, and the middle of the connecting rod member 3 is hinged to the first hinge shaft 11 on the fixing plate 7. The fixing plate 7 is fixed on the side plate of the vehicle frame 5.

[0030] In some embodiments, the connecting rod member 3 includes a first hinge cylinder cooperating with the second hinge shaft, a second hinge cylinder cooperating with the first hinge shaft 11, and a third hinge cylinder cooperating with the third hinge shaft. The first hinge cylinder and the second hinge cylinder are connected by a first connecting rod, the first hinge cylinder and the third hinge cylinder are connected by a second connecting rod, and the included angle β between the first connecting rod and the second connecting rod ranges from 90° to 180°.

[0031] In some embodiments, the axes of the two driving members are arranged at an included angle α, and the range of the included angle α is 0 to 60°.

[0032] In some possible embodiments, the plane containing the axes of the two driving members is horizontally arranged, that is, the two driving members push the connecting rod member 3 to rotate around the axis of its first hinge shaft 11 on the horizontal plane, so as to push the brake block 6 to press against the I-beam track 10. This way can arrange the brake cylinder 1 on both sides of the vehicle frame 5, thereby avoiding interference during operation. In addition, the braking force is large by the braking method of the two driving members, which can meet the braking requirements of the monorail crane during operation.

[0033] In another embodiment, a monorail crane is further provided. A plurality of the above-mentioned brake-carrying trolleys are arranged on the monorail crane. The suspension position at the bottom of the vehicle frame 5 of the brake-carrying trolley is used to connect to the top of suspension components such as a lifting beam and a main engine box. When braking is required during the operation of the monorail crane, the brake cylinders on each brake trolley are depressurized to quickly brake.
