[0001] This invention belongs to the field of braking device technology, specifically relating to a mining monorail crane and its braking and bearing device. Background Technology

[0002] A coal mine monorail is a device that runs on a single overhead track in the coal mine. Multiple braking devices are installed on the monorail train to ensure the safe operation of the locomotive. Some braking devices are located on the drive unit and the driver's cab. There are also monorails with individual braking trolleys installed in front of and behind the personnel car.

[0003] The existing braking device has a brake spring located below the track and perpendicular to the track. It includes a brake cylinder with spring return, a brake plate connected to the brake cylinder, a brake plate hinged in the middle to the frame, and a slide rod connected to the other end of the brake plate. The action of the two slide rods is controlled by the action of a single brake cylinder, and the slide rods push the brake block to brake the track web.

[0004] Existing braking devices are relatively tall, especially when they are installed on the lifting beam, which can interfere with the beam during operation. The lifting beam is the main load position of the locomotive, and braking of the beam is crucial. Therefore, it is necessary to develop a braking trolley with a compact structure, low overall height, and strong braking capacity. Summary of the Invention

[0007] The brake block assembly includes a slide rod and a brake block disposed at one end of the slide rod, and a first inclined surface is provided at the other end of the slide rod;

[0008] One end of the push rod is hinged to one end of the drive member, and the other end of the push rod is provided with a second inclined surface, with the first inclined surface and the second inclined surface in contact and connection.

[0009] The drive member is configured to, upon receiving a braking signal, control the push rod to move along a first direction to drive the slide rod to move along a second direction, wherein the first direction is perpendicular to the second direction and the second direction is perpendicular to the web of the I-beam track.

[0010] In one possible embodiment, the drive element is configured as a double-acting hydraulic cylinder with spring return or a double-acting pneumatic cylinder with spring return.

[0011] In one possible embodiment, the two piston rods of the drive member are respectively connected to a push rod member, and the second inclined surfaces of the two push rod members respectively contact the first inclined surfaces of the two slide rods; a sleeve is fixedly provided at the front and rear of the side plate of the frame, and the sleeve has a first hole with an axis in a first direction and a second hole with an axis in a second direction. The first hole and the second hole are connected, the push rod member moves in the first hole, and the slide rod moves in the second hole.

[0012] In one possible embodiment, the slide bar is provided with a limiting groove, the sleeve is provided with a limiting hole, a limiting rod is installed in the limiting hole, and the limiting rod extends into the limiting groove.

[0013] In one possible embodiment, a return spring is fitted onto the slide bar, the return spring being used to keep the first inclined surface in contact with the second inclined surface.

[0014] In one possible embodiment, a limiting plate is provided in the front-rear direction of the side plate of the frame, and a baffle is provided on the push rod. The baffle is used to abut against the limiting plate when the telescopic rod of the drive member retracts.

[0018] The present invention also provides a mining monorail crane equipped with the above-mentioned braking and bearing device, which can improve the overall safety performance of the monorail crane by setting the braking and bearing device.

[0019] The beneficial effects of this invention are as follows: By installing a braking device on the carrying trolley, a dedicated braking trolley is eliminated, reducing the overall length of the monorail crane train; by arranging the driving components of the braking device on both sides of the carrying trolley frame, rather than at the bottom, the carrying trolley can be installed in the same way as a regular carrying trolley, avoiding interference with other components and improving the versatility of the structure.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] In the description of this specification, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with an embodiment or example that are included in at least one embodiment or example of the present invention. In this invention, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] Referring to Figures 1-5, this embodiment provides a braking load-bearing device, including a frame 7 with a channel formed in the middle for an I-beam rail to pass through. Two sets of running wheels 8 are provided on the frame 7, and the running wheels 8 run on the lower flanges on both sides of the web of the I-beam rail. A suspension part 6 is provided at the bottom of the frame 7, which is hinged to the monorail suspension component.

[0030] Referring to Figures 3-5, a drive member is provided on each side of the frame 7. One end of the drive member is hinged to one end of a push rod 5, and the other end of the push rod 5 is provided with a first inclined surface 51. The push rod 5 moves along a first direction under the action of the drive member. Optionally, the first direction is parallel to the axis of the drive member. A slide rod 9 is installed on the frame 7. A brake block 4 is provided at one end of the slide rod 9, and a second inclined surface 91 is provided at the other end of the slide rod 9. The second inclined surface 91 is in contact with the first inclined surface 51. The slide rod 9 moves along a second direction. Optionally, the first direction is perpendicular to the second direction. Specifically, the second direction can be the direction perpendicular to the web of the I-beam track.

[0031] In other words, the push rod 5 is controlled to move along the first direction by the action of the driving component, and then the first inclined surface 51 of the push rod 5 acts on the second inclined surface 91, thereby pushing the slide rod 9 to move along the second direction, and causing the brake block 4 to act on the web of the I-beam track to perform braking.

[0032] Referring to Figure 5, in some possible embodiments, a return spring 94 is provided on the slide rod 9. The two ends of the return spring 94 abut against the retaining ring provided on the slide rod 9 and the step inside the sleeve 3 provided on the frame 7. Through the action of the return spring 94, the slide rod 9 can always be kept in contact with the push rod 5.

[0033] In some embodiments, a sleeve 3 is provided on the frame 7. The sleeve 3 has a first hole in a first direction and a second hole in a second direction, which are connected. The push rod 5 moves within the first hole, and the slide rod 9 moves within the second hole. The second inclined surface 91 of the slide rod 9 contacts the first inclined surface 51 of the push rod 5 within the sleeve 3.

[0034] In some embodiments, the drive element is configured as a double-acting hydraulic cylinder 1 with spring return or a double-acting pneumatic cylinder with spring return. The double-acting hydraulic cylinder 1 has a double-acting piston rod, and the two piston rods are respectively connected to a push rod 5. The two push rods 5 are then respectively connected to a slide rod 9. The two slide rods 9 are respectively slidably disposed in sleeves 3 located at the front and rear of the side plates on a frame 7.

[0035] Referring to Figure 5, in some possible embodiments, the slide rod 9 is provided with a limiting groove 92, and the sleeve 3 is provided with a limiting hole. A limiting rod 93 is installed in the limiting hole and extends into the limiting groove 92. The movement range of the slide rod 9 is limited by the movement of the limiting rod 93 within the limiting groove 92.

[0036] In some possible implementations, a limiting plate 2 is provided in the front-rear direction of the side plate of the frame, and a baffle is provided on the push rod 5. The baffle is used to abut against the limiting plate 2 when the piston rod of the bidirectional hydraulic cylinder 1 retracts. This arrangement can reduce the problem of asynchronous extension and retraction of the piston rod of the bidirectional hydraulic cylinder 1.

[0037] In some possible embodiments, the drive unit is configured as a one-way hydraulic cylinder with spring return or a one-way pneumatic cylinder with spring return, one end of the drive unit is connected to the frame 7, and the piston rod end of the drive unit is hinged to the push rod 5.

[0038] In the above implementation, the axes of the two drive components are arranged in parallel and on both sides of the frame 7. This structure is compact, has a low space occupancy rate, and minimizes braking force loss. Moreover, the dual-row braking structure provides a large braking force.

[0039] In some embodiments, the present invention also provides a monorail crane equipped with the braking bearing device described in the above embodiments. The suspension part 6 at the bottom of the frame 7 of the braking bearing device is used to connect to the top of the suspension components (such as the lifting beam, main unit box, etc.). When the monorail crane is in operation and braking, the drive components on each braking bearing device release pressure and quickly engage the brake.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or modifications can be made to some or all of the technical solutions, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
