Description

Technical Field

[0001] The utility model belongs to the technical field of rail vehicles, in particular to a cabin cargo transfer rail vehicle with a walking steady-state monitoring function. Background Art

[0002] Due to the limitation of cabin space, it is more convenient and efficient to use a crane to move the cargo when loading and unloading cargo in the cabin. In the process of rail crane moving and transporting cargo, in order to ensure the safety of lifting, it is generally necessary to ensure that the trolley moves as evenly as possible on the track. For electric rail cranes, it is difficult to ensure uniform speed in the event of a malfunction. For hand-pulled rail cranes, their movement is greatly affected by factors, and it is even more difficult to maintain a uniform speed, which brings greater safety hazards to the lifting operation. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a cargo-transferring rail vehicle for a cabin with a walking steady-state monitoring function. The rolling part of the walking steady-state monitoring device that follows the synchronous displacement of the trolley contacts the friction track and rotates, and then the rotation speed of the rolling part is detected to determine whether the trolley is moving at a uniform speed, thereby realizing the walking steady-state monitoring function during the operation of the rail vehicle.

[0004] Technical solution: To achieve the above purpose, the cargo-transfer rail vehicle for cabins of the utility model with a walking steady-state monitoring function comprises a trolley and a reduction box that travel along the track, and the trolley and the reduction box are connected by a hanging plate on which a lifting component is suspended;

[0005] It also includes a walking steady-state monitoring device set on the track through a guide rail, the guide rail is parallel to the track, the walking steady-state monitoring device is connected to the hanging plate, and the walking of the trolley drives the walking steady-state monitoring device to move synchronously along the track; the walking steady-state monitoring device includes a rolling part and a speed monitoring component for detecting the speed of the rolling part, and the rolling part that moves synchronously with the trolley rotates by contacting the friction track.

[0006] Furthermore, the walking steady-state monitoring device includes an elastic seat corresponding to a rolling part, the rolling part is rotatably arranged on the elastic seat, the rolling part is vertically arranged on the side of the track, the elastic expansion and contraction direction of the elastic seat is perpendicular to the length direction of the track, and the rolling part contacts the side of the track through the elastic tension provided by the elastic seat.

[0007] Furthermore, the track is an I-beam, and the rolling part is a roller rotatably mounted on an elastic seat via a rotating shaft. The roller is arranged to be rolled laterally relative to the I-beam by the elastic tension provided by the elastic seat.

[0008] Furthermore, the elastic telescopic end of the elastic seat is connected to a connecting plate extending downward, and the elastic seat slidably arranged on the guide rail is connected to the hanging plate through the connecting plate.

[0009] Furthermore, a gear is coaxially mounted on the rotating shaft, and the rotation speed monitoring component is a speed sensor mounted on the connecting plate facing the tooth portion of the gear.

[0010] Furthermore, the rotating shaft corresponding to the rolling part is arranged on a holding brake located on the elastic seat, and when the holding brake is in a holding rotating shaft state, the rolling part is braked so that the rolling part and the track form a sliding friction braking structure.

[0011] Beneficial effect: The utility model realizes the walking steady-state monitoring function during the operation of the rail vehicle by having the rolling part 8 of the walking steady-state monitoring device 7 that follows the synchronous displacement of the trolley contact the friction track and rotates, and then detecting the rotation speed of the rolling part, thereby determining whether the trolley is walking at a uniform speed, thereby realizing the walking steady-state monitoring function during the operation of the rail vehicle. If the trolley maintains a uniform speed, its walking steady-state condition is good. The greater the difference in the walking speed of the trolley, the worse its walking steady-state condition. When the walking steady-state condition is poor, it is not only easy to cause damage to the driving equipment, but also brings greater safety hazards to the cargo lifting. Therefore, walking steady-state monitoring is even more important. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Attached Figure 2 It is a structural schematic diagram of a walking steady-state monitoring device. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] As attached Figure 1 and attached Figure 2As shown, the cabin cargo transfer rail vehicle with a walking steady-state monitoring function includes a trolley 3 and a reduction box 4 that travel along the track 1, and the trolley 3 and the reduction box 4 are connected by a hanging plate 5 on which a lifting component 2 is suspended; it also includes a walking steady-state monitoring device 7 set on the track 1 through a guide rail 6, and the guide rail 6 is parallel to the track 1. The walking steady-state monitoring device 7 is connected to the hanging plate 5, and the walking of the trolley 3 drives the walking steady-state monitoring device 7 to move synchronously along the track 1; the walking steady-state monitoring device 7 includes a rolling part 8 and a speed monitoring component 9 for detecting the speed of the rolling part 8, and the rolling part 8 that moves synchronously with the trolley 3 rotates by contacting the friction track 1. The utility model realizes the walking steady-state monitoring function in the process of rail driving operation by having the rolling part 8 of the walking steady-state monitoring device 7 that follows the synchronous displacement of the trolley 3 contact the friction track 1 and rotate, and then detects the rotation speed of the rolling part 8, thereby determining whether the trolley is walking at a uniform speed, and further realizing the walking steady-state monitoring function in the process of rail driving operation. If the trolley maintains a uniform speed, its walking steady-state condition is good. The greater the difference in the walking speed of the trolley, the worse its walking steady-state condition. When the walking steady-state condition is poor, it is not only easy to cause damage to the driving equipment, but also brings greater safety hazards to cargo lifting. Walking steady-state monitoring is even more important.

[0016] As attached Figure 2 As shown, the walking steady-state monitoring device 7 includes an elastic seat corresponding to the rolling part 8, the rolling part 8 is rotatably arranged on the elastic seat, the rolling part 8 is arranged on the side of the track 1 in a vertical posture, the elastic expansion direction of the elastic seat is perpendicular to the length direction of the track 1, and the rolling part 8 contacts the side of the track 1 through the elastic tension provided by the elastic seat. The purpose of setting the elastic seat is to keep the rolling part 8 in a state of always being able to contact the track 1, so as to achieve the real-time effectiveness of walking steady-state monitoring.

[0017] Among them, the elastic seat includes a base 12 installed on the slider 60 of the guide rail 6, a movable rod 13 that slides laterally and passes through the base 12, a movable support plate 11 connected to the front end of the movable rod 13, a retaining ring 15 installed at the rear end of the movable rod 13 through a nut 17, and a spring 16 on the rod body of the movable rod 13 between the base 12 and the retaining ring 15. The spring 16 is in an elastically compressed state, so the spring 16 has a rebound tendency force, thereby applying elastic force to the retaining ring 15, and for the movable rod 13, providing the movable rod 13 with a pulling force to pull the rolling part 8.

[0018] More specifically, in the present invention, as a preferred embodiment, the track 1 is an I-beam, which is connected to the inner cabin roof of the cabin to facilitate the lifting of cargo, and the rolling portion 8 is a roller rotatably mounted on an elastic seat through a rotating shaft 80, and the roller is set to roll laterally relative to the I-beam through the elastic tension provided by the elastic seat.

[0019] The elastically retractable end of the elastic seat is connected with a connecting plate 20 extending downward. More specifically, the connecting plate 20 is connected to the movable support plate 11 by bolts, and the elastic seat slidably arranged on the guide rail 6 is connected to the hanging plate 5 by the connecting plate 20.

[0020] In the present utility model, as shown in the attached Figure 2 As shown, a gear 19 is coaxially mounted on the rotating shaft 80, and the speed monitoring component 9 is a speed sensor mounted on the connecting plate 20 facing the tooth portion of the gear 19. The rotating shaft 80 corresponding to the rolling part 8 is provided with a brake 18 located on an elastic seat. When the brake 18 brakes the rotating shaft 80, the rolling part 8 is braked, so that the rolling part 8 and the track 1 form a sliding friction brake structure. When the speed is uneven, it means that the walking steady state working condition is poor. At this time, the brake 18 brakes the rotating shaft 80, thereby braking the rolling part 8, and using the friction between the rolling part 8 and the track 1, a sliding friction brake structure for emergency braking is formed, and then the staff performs maintenance.

[0021] The above is only 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 principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
