[0027] As shown in Figures 1-2 The transfer equipment 5 suitable for the robot in the rail train maintenance warehouse described in the embodiment of the application mainly comprises a lifting mechanism 51, a ditch transition plate 52 and a ground transition plate 53.
[0028] The lifting mechanism 51 is installed in the ditch 2, and the lifting mechanism 51 has a liftable platform 513, which is used for carrying the robot 4.
[0029] The ditch transition plate 52 can be installed in the ditch 2 by, for example, bolts. The ditch transition plate 52 is installed on at least one side of the lifting mechanism 51 along the length direction of the ditch 2, for the convenience of distinction, here it can be said that the ditch transition plate 52 is located on the front side and / or rear side of the lifting mechanism 51, and preferably the ditch transition plate 52 is installed on both sides of the lifting mechanism 51. The top of the ditch transition plate 52 has a smooth transition slope from high to low, the low end of the slope is flush with the bottom surface of the ditch 2, and the high end of the slope is flush with the top surface of the platform 513 in the low position.
[0030] The ground transition plate 53 can also be installed on the ground 1 below the track 3 by, for example, bolts. The ground transition plate 53 is installed on at least one side of the lifting mechanism 51 perpendicular to the length direction of the ditch 2, here it can be said that the ground transition plate 53 is located on the left side and / or right side of the lifting mechanism 51, and preferably the ground transition plate 53 is installed on both sides of the lifting mechanism 51. The ground transition plate 53 is used to fill the gap between the platform 513 and the ground 1.
[0031] The platform 513 can be raised or lowered in the trench 2. When the platform 513 is raised, it is in a high position, and the robot 4 can enter or exit the trench 2 through the ground transition plate 53 on the platform 513. When the platform 513 is lowered, it is in a low position, and the robot 4 can transfer between the trench 2 and the platform 513 through the trench transition plate 52 on the platform 513. Therefore, the robot 4 can be transferred between the trench 2 and the ground 1 by the transfer device 5 described in the embodiments of the present application. The lifting mechanism 51 is installed in the trench 2, but after the platform 513 is lowered, the overall height is contracted to a smaller size, which does not affect the normal work of the robot 4 at this position. The transfer device 5 described in the embodiments of the present application does not require civil engineering reconstruction of the original site, is easy to install and deploy, and almost does not affect the original site after installation. At the same time, it has a simple structure, low cost, and reliable performance.
[0032] As an optional embodiment, as shown in Figure 4 The lifting mechanism 51 can include a base 511, a scissor support 512, and a telescopic mechanism 514 in addition to the platform 513.
[0033] The base 511 can be installed in the trench 2 by, for example, bolts. The platform 513 is installed above the base 511 by the scissor support 512. The middle points of the fork arms of the scissor support 512 are hingedly connected to each other. The upper and lower ends of one side of the fork arms are hingedly connected to the base 511 and the platform 513, respectively. The upper and lower ends of the other side of the fork arms are slidingly connected to the base 511 and the platform 513, respectively. The telescopic mechanism 514 is installed between the base 511 and the scissor support 512. The telescopic mechanism 514 can be, for example, an oil cylinder. Through the telescopic movement of the telescopic mechanism 514, the platform 513 can perform lifting movement.
[0034] As shown in Figure 3 The transfer device 5 described in the embodiments of the present application can also include a limiting assembly. The limiting assembly can include a stand 541, a proximity switch 542, and a sensing sheet 543.
[0035] The stand 541 is vertically arranged. The lower end of the stand 541 can be installed in the trench 2, and is preferably arranged close to the side wall of the trench 2 to avoid interfering with other mechanisms. The lower end of the stand 541 can also be connected to the base 511 by, for example, welding, and is preferably arranged close to the edge of the base 511 to avoid interfering with other mechanisms. Since the base 511 is installed in the trench 2 by, for example, bolts, the lower end of the stand 541 connected to the base 511 is actually installed in the trench 2.
[0036] The proximity switch 542 and the sensing plate 543 work together. One of them is installed on the column 541, and the other is installed on the edge of the platform 513 and can move up and down with the platform 513.
[0037] Limiting components can be used to obtain position information of platform 513. For example, when proximity switch 542 approaches sensing plate 543, it can provide a feedback signal, which can be used to control platform 513 to stop rising. At this time, the position of platform 513 can be designed to be exactly at the high position.
[0038] As an optional implementation, the proximity switch 542 can be installed on the edge of the platform 513, and multiple sensing elements 543, such as three sensing elements 543, can be installed on the column 541, spaced apart from top to bottom. The sensing element 543 at the lowest position corresponds to the position of the platform 513 when it is lowered to its lowest position. Considering infrastructure errors, there may be a height difference between the ground 1 on both sides of the trench 2. Therefore, the two sensing elements 543 at the highest and second highest positions correspond to the positions of the platform 513 when it is raised to its highest position and corresponds to the left or right side of the ground 1, respectively. If the height difference between the ground 1 on both sides of the trench 2 is negligible, only one sensing element 543 can be used to provide the high-position information.
[0039] The position of the sensor 543 on the column 541 can also be designed to be adjustable up and down, so as to adjust for trenches 2 of different depths.
[0040] To further improve accuracy, a limit component can be installed at each of the four corners of platform 513. Integrating information from multiple limit components helps to more accurately determine the position of platform 513.
[0041] like Figure 3 As shown in the embodiments of this application, the transfer device 5 may further include a safety component. The safety component is installed on at least one edge of the top of the platform 513, and the safety component includes a laser transceiver 551 and a reflector 552 respectively disposed at both ends of the edge of the platform 513.
[0042] The laser transceiver 551 includes a laser emitting unit and a laser receiving unit. The laser emitting unit emits laser light, and the laser receiving unit receives the reflected laser light. The laser light emitted by the laser emitting unit is reflected by a reflector 552 and received by the laser receiving unit, thus forming a laser fence between the laser transceiver 551 and the reflector 552. When the laser fence is blocked by the robot 4 moving in and out of the platform 513, the laser receiving unit cannot receive the reflected laser light, and at this time, it can transmit signals outward.
[0043] The safety assembly can be installed on the four side edges of the top of the platform 513, that is, four laser fences can be formed on the four sides of the platform 513 to completely surround the top plane of the platform 513. When the robot 4 enters or exits the platform 513, the motion information of the robot 4 can be obtained, and the lifting action can be performed only when the robot 4 completely enters or exits the platform 513, so as to ensure the safety of the robot 4. Since the safety assembly moves with the platform 513, the platform 513 can obtain the alarm information of the robot 4 accidentally crossing the boundary on the platform 513 at any position.
[0044] A plurality of transfer devices 5 described in the embodiments of the present application can be installed in a plurality of trenches of the maintenance library, and can be controlled in linkage with the robot 4 to realize the function of the robot 4 working on any lane.
[0045] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
[0046] The above-mentioned preferred embodiments should not be regarded as a limitation of the present application, and the protection scope of the present application should be defined by the scope of the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
