Description

Technical Field

[0001] This utility model relates to the field of existing railway building renovation technology, and in particular to a trolley for renovating platform canopy gutters when the railway is not in operation. Background Technology

[0002] refer to Figure 1 and Figure 2 As shown, both sides of the canopy 11 of the railway platform 13 are equipped with external gutters 10 to collect rainwater and drainage from the canopy. After prolonged use, the gutters may become clogged, accumulate water, and leak, requiring replacement of the gutters without replacing the canopy roof panels.

[0003] In existing technologies, gutter renovation is carried out by erecting scaffolding below it or using machinery such as articulated boom lifts. However, the gutter is located below railway track 14. If the existing conventional method is used to replace the gutter, on the one hand, trains must be stopped; on the other hand, there are high-voltage live contact wires installed below the canopy gutters. If the replacement is carried out by erecting scaffolding below the canopy or using machinery such as articulated boom lifts, there is also a risk of electric shock. Utility Model Content

[0004] This utility model provides a trolley for non-stop renovation of railway platform canopy gutters, avoiding high-voltage electric shock during construction and preventing impact on train operation.

[0005] According to one aspect of this utility model, a trolley for modifying the gutter of a platform canopy under railway non-stop operation is provided, comprising: a crane, an operating platform, and a connection structure between the operating platform and the canopy; the crane is mounted on the operating platform; the connection structure includes support members and slide rails, and pulleys adapted to the slide rails; the support members are respectively mounted on the keel of two adjacent canopies, with at least two support members mounted on each canopy; two slide rails are respectively mounted parallel to each other on the support members mounted on the two adjacent canopies; two sets of pulleys are respectively mounted below the operating platform, the position of the pulleys being adapted to the slide rails, and the operating platform can reciprocate along the slide rails.

[0006] This utility model discloses a trolley for modifying platform canopy gutters when railway operations are not interrupted. This trolley is positioned above the space between two canopies. During gutter replacement, it avoids the significant safety risks associated with conventional installation and dismantling methods, such as multiple cranes and articulated boom cranes encroaching on train clearances. It also effectively prevents the danger of electric shock to workers and machinery operating above the overhead contact line. Furthermore, it avoids the need for scaffolding below the gutter, which would disrupt train operations. Additionally, one trolley can handle the modification of two gutters simultaneously, significantly improving work efficiency compared to the cumbersome operation of large machinery.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0022] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising" or "including" include not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Figure 3 The diagram schematically illustrates the structure and usage of a trolley for modifying platform canopy gutters under railway non-stop operation, according to one embodiment of the present invention.

[0025] refer to Figure 3 As shown, the trolley is mounted between two adjacent canopies 11. The trolley includes a crane 28, an operating platform 24, a connection structure between the trolley and the canopy, and a protective device 27 installed below the operating platform 24.

[0026] The crane 28 is positioned above the operating platform 24. Both the old gutters that have been removed and the new gutters that are to be installed can be temporarily placed on the operating platform 24.

[0027] The two ends of the operating platform 24 are respectively set above the keel 12 of the two canopies 11.

[0028] A protective device 27 is provided below the operating platform 24. The protective device 27 is connected to the operating platform via a telescopic rod 26.

[0029] The protective device 27 can be a protective net, which is set below the operating platform 24 via a telescopic rod 26 to catch items that may fall during the hoisting of the gutter 10.

[0030] Rainwater collected by gutter 10 can be discharged through drain pipe 16 connected to gutter 10.

[0031] Figure 4 and Figure 5 schematically shown Figure 3 The diagram shows the connection structure between the trolley and the canopy for modifying the platform canopy gutter when the railway is not in operation.

[0032] refer to Figure 4 and Figure 5 As shown, the connection structure between the trolley and the canopy includes a support member 21 and a slide rail 23, as well as a pulley 241 adapted to the slide rail 23.

[0033] Support members 21 are respectively installed on the keel 12 of two adjacent canopies 11, with at least two support members 21 installed on each canopy 11. In order to distribute the weight of the operating platform 24, one support member 21 can be installed on each keel 12.

[0034] Two slide rails 23 are respectively and parallelly installed on the support members 21 installed on the two adjacent canopies 11. The slide rails 23 can be made of I-beams or other long strip materials and are laid continuously along the length of the canopy 11.

[0035] The support member 21 can be made of square steel, and its lower surface can be connected to the keel 12 of the canopy by welding. The upper surface of the support member 21 can also be provided with a support plate 22, and the slide rail 23 is placed above the support plate 22. The support plate 22 can be made of galvanized steel sheet.

[0036] A set of pulleys 241 is provided on the lower sides of the operating platform 24. The position of the pulleys 241 is adapted to the slide rail 23, and the operating platform 24 can move back and forth along the slide rail 23.

[0037] Because the operating platform 24 is quite heavy, if a clamp is made directly on the top panel of the canopy 11 to install the slide rail, the top panel cannot support the weight of the operating platform 24.

[0038] Figure 6 The diagram schematically illustrates a pulley anti-fall-off structure for a trolley used to modify a platform canopy gutter under railway non-stop operation, according to one embodiment of the present invention.

[0039] refer to Figure 6As shown, the track 23 is made of I-beams with an "H"-shaped cross-section. The pulley 241 is positioned within the upper groove of the I-beam. Both outer sides of the pulley 241 are equipped with baffles 242 that accommodate the side plates of the I-beam. The baffles 242 have an "L"-shaped cross-section. This pulley anti-detachment structure effectively prevents the pulley 241 from detaching from the I-beam.

[0040] Figure 7 This is a schematic diagram of the pulley locking structure of a trolley used for modifying the gutter of a platform canopy under the condition of railway non-stop operation, according to one embodiment of the present invention.

[0041] refer to Figure 7 As shown, multiple sockets 231 can be set on the track 23. When the operation stops or there is a strong wind, and it is necessary to fix the position of the operating platform 24, the plug rod 31 can be inserted into the socket to restrict the movement of the operating platform 24.

[0042] The steps for modifying the station canopy gutter by installing a trolley in this utility model are as follows:

[0043] 1. Locate the corresponding keel 12 on the panels of two adjacent canopies 11, and cut holes in the panel at that location. The number of holes can be determined based on the length of the track 23 to be laid later; the longer the track, the more holes are needed.

[0044] 2. A 100*100*4mm galvanized square tube is used as a support component 21, which is welded to the keel through the cut holes of the canopy roof panel and serves as a fixing point for supporting the operating platform 24.

[0045] 3. After the galvanized square tubes are welded, the openings are first filled with roof panels, and then waterproofed with flexible self-adhesive waterproof membrane or other waterproof materials 29. The edges of the waterproof material 29 can be fitted with aluminum strips 30 for fixing it to the awning, and a neutral sealant can be applied to the underside of the aluminum strips 30.

[0046] 4. A galvanized steel plate is welded to the upper surface of each galvanized square tube that serves as a support member 21.

[0047] 5. Weld I-beams onto the galvanized steel sheet, ensuring that the I-beams on the two canopies are parallel.

[0048] 6. Assemble the operating platform 24 and pulley 241 into a whole on the ground. Then, take advantage of the nighttime train shutdown to hoist the operating platform 24 onto the I-beam and adjust it to ensure that the operating platform 24 can slide along the I-beam.

[0049] 7. Install the crane 28 above the operating platform 24.

[0050] 8. Remove and hoist the old gutters.

[0051] 9. Hoist and install the new gutter. 10.

[0052] 10. During the nighttime train shutdown period, take advantage of the maintenance window to lift the crane 28 and operating platform 24 off the canopy 11.

[0053] Track 23, support plate 22 and support 21 do not need to be removed and can be used for the renovation of canopy roofs, etc.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
