Description

Technical Field

[0001] The utility model belongs to the technical field of rail-mounted locomotives, and in particular relates to a monorail crane driving device. Background Art

[0002] A monorail crane is an aerial transport system in which a locomotive travels back and forth on a suspended I-shaped rail. It is secured to the tunnel roof by a flexible belt, and the locomotive's running wheels engage the sides of the I-beam, preventing derailment or falling off the track. Due to its advantages, such as a small cross-section, high space utilization, unrestricted transport routes, low operating resistance, strong climbing ability, automatic lifting, easy loading and unloading, high efficiency, minimal labor, and low investment and maintenance costs, it is widely used in industrial production and plays a significant role in transporting goods and personnel. Therefore, monorail cranes are used in a wide range of fields, including coal mine tunnels, highway tunnels, and railway tunnels.

[0003] In a monorail crane, the crane is suspended on the lower side of the suspension and is driven to move on the hanging rail by a driving device. However, during use, although the hanging rail can play the role of guidance and exerting external force to fix the suspension, the traditional driving device uses gears for driving. Since the driving gear is directly engaged with the hanging rail, the hanging rail will vibrate during the transmission of the driving gear, affecting the fixing effect of the guide rail on the top of the lane or tunnel, posing an obvious safety hazard. At the same time, since the driving gear is directly used in conjunction with the hanging rail, the volume and model of the hanging rail must be determined according to the project volume and the volume of the lower crane frame during use, and then the model of the driving gear is determined according to the volume and model of the hanging rail. As a result, the overall driving device has large differences in use, and cannot be mass-produced and standardized during use.

[0004] Based on this, the present invention proposes a novel monorail crane driving device to solve the problems existing in the above-mentioned background technology. Utility Model Content

[0025] The utility model provides an embodiment:

[0026] like Figures 1 to 5As shown, a monorail crane drive device is arranged on the inner side of the crane frame 101 below the hanging rail 102, including a flexible conveyor belt 10, a mounting frame 1, a moving mechanism and a clamping mechanism; the flexible conveyor belt 10 is installed directly below the hanging rail and laid along the length direction of the hanging rail, and a mounting frame 1 is provided on the cross frame 103 of the crane frame, and the flexible conveyor belt 10 is arranged through the mounting frame 1; the moving mechanism includes a driving motor 2 and a driving wheel 3, the driving motor 2 is installed on the mounting frame 1, the driving wheel 3 is connected to the driving end of the driving motor 2, and the wheel surface of the driving wheel 3 is in contact with the side of the flexible conveyor belt 10 for transmission; the clamping mechanism includes a clamping wheel 8 and a clamping adjustment assembly, the clamping adjustment assembly is arranged on the mounting frame 1, the wheel surface of the clamping wheel 8 is in contact with the side of the flexible conveyor belt 10, the driving wheel 3 and the clamping wheel 8 are respectively located on both sides of the flexible conveyor belt 10, and the distance between the wheel surface of the clamping wheel 8 and the flexible conveyor belt 10 is adjusted by the clamping adjustment assembly.

[0027] It is worth noting that, by setting the driving wheel 3 and the clamping wheel 8, the flexible conveyor belt 10 can be clamped during use, thereby realizing a clamping connection between the monorail crane drive device and the flexible conveyor belt 10. By setting the driving motor 2 and the driving wheel 3, after the driving wheel 3 and the clamping wheel 8 clamp the flexible conveyor belt 10, the driving motor 2 drives the driving wheel 3 to rotate, thereby adjusting the position of the crane frame 101 on the lower side of the hanging rail 102, so as to realize the movement of the crane frame 101 in the length direction of the flexible conveyor belt 10. By setting the clamping adjustment component, the relative distance between the driving wheel 3 and the clamping wheel 8 and the actual prestress during clamping can be adjusted according to the width of the flexible conveyor belt 10 during use, so as to be suitable for the use of flexible conveyor belts 10 of different widths.

[0028] The clamping adjustment assembly includes a push rod 5, a first connecting rod 6, a second connecting rod 7, a connecting piece 9 and a connecting rod mounting frame 12. The push rod 5 is arranged below the mounting frame 1, and the two ends of the first connecting rod 6 are rotatably connected to the telescopic end of the push rod 5 and the second connecting rod 7 respectively; the connecting rod mounting frame 12 is fixed on the mounting frame 1, and the connecting piece 9 is slidably set on the connecting rod mounting frame 12, and the second connecting rod 7 is rotatably connected to the connecting rod mounting frame 12. The second connecting rod 7 has a guide groove 71 that slides with the connecting piece 9, and the clamping wheel 8 is connected to the upper end of the connecting piece 9; a push rod frame 4 is fixed to the lower end of the mounting frame 1, and the push rod 5 is horizontally mounted on the push rod frame 4. The push rod frame 4 is a U-shaped bracket bolted to the lower end of the mounting frame 1.

[0029] It is noteworthy that the arrangement of the push rod 5 allows for coordinated adjustment of the position of the clamping wheel 8, enabling the driving wheel 3 and the clamping wheel 8 to clamp the flexible conveyor belt 10 and provide a prestressed force after clamping. The arrangement of the first and second linkage rods 6 and 7 achieves a coordinated action, clamping the flexible conveyor belt 10 under the adjustment of the push rod 5. This results in a simple structure and ease of use. The arrangement of the connecting member 9 converts the rotational motion of the second linkage rod 7 into horizontal motion of the connecting member 9 and the clamping wheel 8. The arrangement of the push rod bracket 4 secures the push rod 5, facilitating its removal and installation during use and securing the push rod 5.

[0030] A connecting bracket 11 is symmetrically arranged on the mounting frame 1, and a belt hole 111 matching the flexible conveyor belt 10 is provided on the connecting bracket 11; the connecting rod mounting frame 12 is located above the first connecting rod 6, and the upper part of the connecting rod mounting frame 12 has a movable groove 121, and the connecting member 9 is slidably connected in the movable groove 121, and the lower part of the connecting rod mounting frame 12 is provided with a connecting shaft 122 that rotates with the second connecting rod.

[0031] It is worth noting that, during use, the movable groove 121 allows the connector 9 to be slidably mounted in the movable groove 121, thereby facilitating the horizontal movement of the clamping wheel 8 through the connector 9 to clamp the flexible conveyor belt 10. The connecting shaft 122 allows the second connecting rod 7 to be symmetrically mounted on both sides of the connecting rod fixing frame 12, facilitating linkage adjustment during use.

[0032] The connecting member 9 includes a baffle 91, a slider 92 and a slide rod 93. The baffle 91 is fixedly arranged on both sides of the slider 92. The slider 92 is slidably connected in the movable groove 121. The inner side of the baffle 91 is in contact with the outer wall of the movable groove 121. The upper end of the slider 92 has a connecting hole that matches the axle of the clamping wheel 8. The slider is guided by the slide rods 93 on both sides thereof. The outer end of the slide rod 93 extends out of the outside of the movable groove 121 and is slidably engaged with the guide groove 71.

[0033] It is worth noting that, during use, the baffle 91 facilitates the sliding installation of the slider 92 within the movable groove 121. The baffle 91 limits and guides the movement of the slider 92, allowing the connecting member 9 to move horizontally under the drive of the second connecting rod 7. During use, the baffle 91, the slide bar 93, and the guide groove 71 connect the connecting member 9 to the second connecting rod 7. During the rotation of the second connecting rod 7, the connecting member 9 is driven to move within the movable groove 121.

[0034] The outer surface of the driving wheel 3 is provided with anti-slip grooves. When in use, the friction between the driving wheel 3 and the flexible conveyor belt 10 is used to drive the crane frame 101 to move along the length direction of the flexible conveyor belt 10; the surface of the clamping wheel 8 is smooth and is rotatably mounted on the connecting member 9.

[0035] As a preferred embodiment, the driving wheel 3 is set to a gear structure, and the flexible conveyor belt 10 is a flexible toothed belt, which can engage with the driving wheel 3 when in use. The surface of the clamping wheel 8 is smooth, and the crane frame 101 is driven to move in the length direction of the flexible conveyor belt 10 through the engagement between the driving wheel 3 and the flexible conveyor belt 10 when in use.

[0036] Working principle:

[0037] Before use, the telescopic rod of the push rod 5 is controlled to extend according to the width of the flexible conveyor belt 10, and the position of the clamping wheel 8 is adjusted so that the clamping wheel 8 moves toward the driving wheel 3, so that the flexible conveyor belt 10 can be tightly clamped between the clamping wheel 8 and the driving wheel 3, achieving the effect of fixing and applying prestress. Then, after clamping, the drive motor 2 is controlled to drive the driving wheel 3 to rotate according to control needs, and the position of the crane frame 101 on the lower side of the hanging rail 102 is adjusted to achieve the movement of the crane frame 101 in the length direction of the flexible conveyor belt 10.

[0038] It is worth noting that the driving motor 2 and the push rod 5 are both existing technologies commonly used in this field, and their specific models and power supply methods can be selected and used according to specific usage requirements during use.

[0039] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
