DETAILED DESCRIPTION

[0038] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] The embodiment of the utility model provides a monorail crane locomotive cab, such as Figure 1-5 As shown, it includes: a body 1, a carrier frame 2, a walking wheel 3, and a guide wheel 4;

[0040] The main body 1 has a space for accommodating a driver; the bearing frame 2 is arranged above the main body 1, and includes a first bearing plate 21 and a second bearing plate 22 symmetrically arranged on both sides of the track 5; a mounting portion 23 is provided on the first bearing plate 21 and the second bearing plate 22; the running wheels 3 are symmetrically arranged on both sides of the track 5, and are respectively mounted on the first bearing plate 21 and the second bearing plate 22, and are suitable for moving along the bearing surface of the track 5; the wheel axle of the guide wheel 4 and the extension direction of the wheel axle of the running wheel 3 form an angle of 70-90°; the guide wheel 4 is installed below the running wheel 3 through the mounting portion 23, and is located at the edge of the bearing surface of the track 5, and is suitable for providing horizontal support force to the edge of the bearing surface of the track 5.

[0041] The track 5 is in the shape of an “I”, i.e., it is composed of a first plane located at the top, a second plane located at the bottom, and a vertical plane connecting the two. The bearing surface of the track 5 refers to the upper surface of the second plane. The edge of the bearing surface of the track 5 refers to the outer edge of the second plane. The horizontal direction refers to the direction parallel to the horizontal plane; the vertical direction refers to the direction perpendicular to the horizontal direction.

[0042] The axle of the guide wheel 4 and the extension direction of the axle of the running wheel 3 form an angle of 70-90°. The axle of the guide wheel 4 is in the vertical direction and can provide horizontal support. The axle of the running wheel 3 can be in the horizontal direction, that is, perpendicular to the extension direction of the axle of the guide wheel 4, or at a certain angle to the horizontal direction. Figure 5 As shown, the wheel axle of the running wheel 3 is a first wheel axle 30, and the wheel axle of the guide wheel 4 is a second wheel axle 40. The running wheel 3 is not completely vertical, that is, the wheel axle of the running wheel 3 is not completely horizontal, but has a certain angle with the horizontal direction.

[0043] For achieving the purpose of the present utility model, the number of the walking wheels 3 and the guide wheels 4 is not unique. In order to better maintain the balance during hanging, in this embodiment, Figure 3 As shown, the running wheels 3 are in two groups, which are respectively located at the two ends of the cab of the monorail crane locomotive, namely, the front wheel group and the rear wheel group; each group of the running wheels 3 is two, which are symmetrically arranged on both sides of the track 5. Similarly, the guide wheels 4 are arranged below each of the running wheels 3, that is, there are four guide wheels 4.

[0044] In order to further improve the stability of the monorail crane cab when driving to a turn, the guide wheel 4 includes a transition section 41 and a straight section 42; the wheel diameter of the transition section 41 is smaller than the wheel diameter of the straight section 42; the transition section 41 is located above the straight section 42 and on the side close to the edge of the bearing surface of the track 5. Figure 4-5 As shown, the transition section 41 is located at the top, close to the edge of the bearing surface of the track 5; the straight section 42 is located at the bottom, away from the edge of the bearing surface of the track 5. Since the transition section is closer to the edge of the bearing surface of the track, when the cab of the monorail crane turns, the guide wheel that provides horizontal support to the edge of the bearing surface of the track will be in close contact with the edge of the bearing surface of the track in the transition section, and the wheel diameter of the straight section is larger, which can achieve vertical limitation to a certain extent, prevent the running wheel from leaving the bearing surface of the track, and maintain balance in the vertical direction.

[0045] As a preferred implementation of this embodiment, the wheel radius of the straight section 42 of the guide wheel 4 can be greater than the distance between the wheel axle of the guide wheel 4 and the edge of the bearing surface. This arrangement can further enhance the limiting function of the guide wheel 4 in the vertical direction and better maintain balance in the vertical direction.

[0046] As a further preferred implementation of this embodiment, the transition section 41 may be a wheel diameter that changes from large to small in a direction from close to the straight section 42 to far away from the straight section 42. Such a slope design can provide better buffering.

[0047] In order to achieve the purpose of the present utility model, the installation method of the guide wheel 4 on the first bearing plate 21 and the second bearing plate 22 is not unique. In this embodiment, a specific design method is provided, and the mounting portion 23 includes a long groove 231 and a support ear 232; the long groove 231 is located above the support ear 232, suitable for accommodating the guide wheel 4; the support ear 232 is perpendicular to the first bearing plate 21 and the second bearing plate 22, and is provided with an axial hole, which is suitable for installing the axle of the guide wheel 4, that is, the second axle 40.

[0048] As a preferred implementation of this embodiment, a brake part 24 is provided on the carrier 2; the brake part 24 includes: a brake cylinder 241, a spring 242, a swing arm 243, a brake guide rod 244, and a brake pad 245;

[0049] The brake cylinder 241 is located below the carrier frame 2, and its telescopic direction is perpendicular to the extension direction of the track 5; the spring 242 is sleeved on the brake cylinder 241; there are two swing arms 243, which are respectively arranged at both ends of the brake cylinder 241; there are two brake guide rods 244, which are respectively installed on the first carrier plate 21 and the second carrier plate 22; the end of the brake guide rod 244 is connected to the end of the swing arm 243, and is parallel to the telescopic direction of the brake cylinder 241; there are two brake pads 245, which are symmetrically arranged on both sides of the track 5; the brake pads 245 are connected to the ends of the brake guide rods 244, and are suitable for clamping or loosening the track 5 under the drive of the brake guide rods 244.

[0050] The working process of the brake part 24 is as follows: when the brake cylinder 241 is extended, the swing arms 243 at both ends move to both sides, driving the brake guide rod 244 to move inward, and then driving the brake pads 245 to clamp the track 5, thereby achieving the braking of the monorail crane cab; when the brake cylinder 241 is retracted, the swing arms 243 at both ends move inward, driving the brake guide rod 244 to move outward, and then driving the brake pads 245 to release the track 5, thereby achieving the driving of the monorail crane cab. The setting of the spring 242 can ensure that the brake cylinder 241 can be reset when the oil pressure is released.

[0051] In order to facilitate the connection between the monorail crane cab and structures such as hanging vehicles or traction equipment, connecting rod seats 25 are provided at both ends of the support frame 2.

[0052] It should be noted that the structural design in the body 1 is not unique. Those skilled in the art can set relevant structures according to actual needs. The structures set in the body 1 include but are not limited to seats 11, operating tables 12, operating handles 13, internal fire extinguishers 14, and display screens 15.

The front wall of the body 1 is provided with cameras 18, locomotive horns 19, locomotive lights 110, antennas 112, and oil pipe holders 113.

[0053] The provision of the oil pipe seat 113 can facilitate the installation of the oil pipe. For example, the oil pipe of the brake cylinder 241 can be installed on the oil pipe seat 113, making space utilization more reasonable and effective.

[0054] In order to ensure the driver's vision and safety when in the cab of the monorail crane locomotive, a guardrail 16 is provided on the front wall of the body 1, and a front windshield 17 is installed at the guardrail 16.

[0055] In order to facilitate the driver to enter and exit the monorail crane cab, a telescopic ladder 114 is provided on the side wall of the body 1. When there is a height difference between the hanging position of the monorail crane cab and the ground, the telescopic ladder 114 can be used to enter and exit the monorail crane cab.

[0056] In this embodiment, a warning light 118 is provided on the top of the main body 1. A tool box 115, a flight plug cover 116, and an external fire extinguisher 117 are provided on the rear wall of the main body 1.

[0057] The monorail crane locomotive cab described in this embodiment works as follows:

[0058] When the monorail crane cab is traveling on the track, the running wheels 3 move on the bearing surface of the track 5 using friction, and the guide wheels 4 are located at the edge of the bearing surface of the track 5, and can provide horizontal support force. When the monorail crane cab turns on the track 5, the four guide wheels 4 can provide horizontal support force in the horizontal direction according to the turning direction to maintain the balance of the monorail crane cab and improve the driving safety of the monorail crane cab.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
