The whole replacement process requires fast and safe to reduce the impact on production.

[0033] In actual operation process, when the trolley lifts out the old trolley, the adjacent two side trolleys lose the constraint and will appear the situation of sliding to the trolley empty position, which causes difficulty in loading the new trolley and low trolley replacement efficiency.

[0034] According to experience, when the new trolley is loaded back, more than 20mm installation gap needs to be left to ensure that the new trolley is loaded smoothly. In the process of replacing the trolley in the past, the replacement time of the trolley is long due to insufficient gap between the trolleys, which has a great impact on production.

[0035] In the related art, there is a technical problem of trolley sliding in the process of replacing the damaged trolley. The trolley supporting device provided by the embodiment can at least solve the technical problem of trolley sliding in the process of replacing the damaged trolley to a certain extent.

[0036] The application will be described below in conjunction with the drawings and specific embodiments:

[0037] As Figure 1 And Figure 2As shown, the trolley supporting device 100 comprises a supporting frame 110 and a plurality of ejection mechanisms 120. The supporting frame 110 has an avoiding hole 110a for avoiding the trolley to be replaced 210; the plurality of ejection mechanisms 120 are respectively installed on both sides of the supporting frame 110 along the first direction, and are respectively used for abutting against the front trolley 220 and the rear trolley 230 located on both sides of the trolley to be replaced 210. The length of the ejection mechanism 120 along the first direction can be adjusted.

[0038] In the height direction, the avoiding hole 110a is through, and the avoiding hole 110a is used for avoiding the trolley to be replaced. The size of the avoiding hole 110a should ensure that the trolley to be replaced 210 can be lifted out through the avoiding hole 110a when the trolley to be replaced 210 is disassembled, and the new trolley can enter between the front trolley 220 and the rear trolley 230 through the hole when the new trolley is installed.

[0039] When the trolley supporting device 100 is used, the first direction is parallel to the running direction of the trolley. Part of the plurality of ejection mechanisms 120 is installed on one side of the supporting frame 110 along the first direction, and the other part is installed on the other side of the supporting frame 110 along the first direction. In this way, when the trolley supporting device 100 is used, along the running direction of the trolley, part of the ejection mechanism 120 is on the front side of the supporting frame 110 and abuts against the front trolley 220 on the front side of the trolley to be replaced 210, and the other part of the ejection mechanism 120 is on the rear side of the supporting frame 110 and abuts against the rear trolley 230 on the rear side of the trolley to be replaced 210.

[0040] In this way, when the damaged trolley to be replaced 210 needs to be replaced, the supporting frame 110 of the trolley supporting device 100 is sleeved outside the trolley to be replaced 210, then the ejection mechanism 120 is elongated and abuts against the front trolley 220 on the front side of the trolley to be replaced 210 and the rear trolley 230 on the rear side of the trolley to be replaced 210, and then the trolley to be replaced 210 is lifted by the lifting device such as a travelling crane. The trolley to be replaced 210 is lifted out through the avoiding hole 110a. After the trolley to be replaced 210 is lifted out, due to the action of the ejection mechanism 120, the front trolley 220 and the rear trolley 230 will not slide. After the trolley to be replaced 210 is lifted out, the lifting device lifts in a new trolley and places it between the front trolley 220 and the rear trolley 230 through the avoiding hole 110a, and then the ejection mechanism 120 is shortened and no longer abuts against the front trolley 220 and the rear trolley 230. Finally, the trolley supporting device 100 is removed, and the replacement of the trolley is completed.

[0041] In some embodiments, the ejection mechanism 120 comprises an ejection member 121 and an abutting member 122. The ejection member 121 is mounted on the support frame 110, and the length of the ejection member 121 in the first direction can be adjusted. The abutting member 122 is mounted on the output end of the ejection member 121, and is used to abut against the front trolley 220 or the rear trolley 230. The abutting member 122 is mounted on the output end of the ejection member 121, and the ejection member 121 drives the abutting member 122 to move in the first direction. In use of the trolley support device 100, the abutting member 122 close to the front trolley 220 abuts against the front trolley 220, and the abutting member 122 close to the rear trolley 230 abuts against the rear trolley 230. The ejection mechanism 120 is designed to comprise the ejection member 121 and the abutting member 122, so that the ejection member 121 and the abutting member 122 can be independently processed and then assembled into the ejection mechanism 120, which can facilitate the processing and manufacturing of the ejection mechanism 120. The ejection member 121 can be a jack, and is not limited in the present application.

[0042] In some embodiments, the abutting member 122 has a limiting groove 122a, and the abutting member 122 abuts against the wheel 201 of the front trolley 220 or the rear trolley 230 through the inner wall of the limiting groove 122a. The wheel 201 is in a cylindrical shape, and the limiting groove 122a can make the abutting member 122 stably contact with the circumferential surface of the wheel 201, prevent the abutting member 122 from accidentally separating from the wheel 201, and enhance the stability and reliability of the trolley support device 100.

[0043] In some embodiments, the limiting groove 122a is an arc-shaped groove.

[0044] In some embodiments, the abutting member 122 is detachably connected to the output end of the ejection member 121. After such design, the abutting member 122 can be flexibly replaced according to the structure or size of the trolley, which widens the application range of the trolley support device 100.

[0045] In some embodiments, four ejection mechanisms 120 are provided, and the four ejection mechanisms 120 are arranged in an array along the first direction and the second direction, and the second direction is perpendicular to the first direction. In use of the trolley support device 100, the second direction is parallel to the width direction of the trolley. After such design, the two ejection mechanisms 120 located on one side of the first direction can abut against the two sides of the front trolley 220 along the width direction respectively, and the two ejection mechanisms 120 located on the other side of the first direction can abut against the two sides of the rear trolley 230 along the width direction respectively, so that the ejection mechanisms 120 can exert uniform force on the front trolley 220 and the rear trolley 230, ensure the force balance of the front trolley 220 and the rear trolley 230, and ensure the distance between different parts of the front trolley 220 and the rear trolley 230 to be consistent.

[0046] In some embodiments, the trolley support device 100 further includes a support member 130 mounted on the support frame 110, which supports the front trolley 220 and / or the back trolley 230. With this design, when using the trolley support device 100, the entire trolley support device 100 can be supported on the front trolley 220 and / or the back trolley 230 by the support member 130. The trolley support device 100 can move along with the trolley, enabling trolley replacement during operation, i.e., realizing online trolley replacement. The support member 130 can support only the front trolley 220, only the back trolley 230, or simultaneously on both the front trolley 220 and the back trolley 230.

[0047] In some embodiments, multiple support members 130 are provided, which are respectively supported on the front carriage 220 and the back carriage 230. Some support members 130 are supported on the front carriage 220, and others are supported on the back carriage 230. This design helps to distribute the supporting force evenly throughout the carriage support device 100, thereby improving the stability of the carriage support device 100 during use.

[0048] The support member 130 can be supported on the body of the trolley. In some embodiments, the support member 130 is supported on the wheels 201 of the front trolley 220 and the rear trolley 230. Supporting the support member 130 on the wheels 201 helps to prevent the support member 130 from interfering with the loading of materials into the trolley.

[0049] In some embodiments, the support member 130 is a rod arranged along the height direction, with its upper end welded to the support frame 110 and its lower end supported on the wheel 201.

[0050] In some embodiments, four support members 130 are provided, arranged in an array along a first direction and a second direction, with the second direction perpendicular to the first direction. When the trolley support device 100 is in use, the second direction is parallel to the width direction of the trolley. With this design, the two support members 130 located on one side of the first direction can support the front trolley 220 on both sides along the width direction, and the two support members 130 located on the other side of the first direction can support the rear trolley 230 on both sides along the width direction. The trolley support device 100 is evenly stressed, ensuring its stability during use.

[0051] In some embodiments, to facilitate the hoisting of the trolley support device 100, the trolley support device 100 also includes a lifting lug 140 mounted on the support frame 110.
