Specific embodiments

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0057] See also Figure 1-Figure 2 , shows a subway screen door 40 installation device according to a preferred embodiment of the present invention, including an assembly structure 10, a transfer bracket 20 and an installation vehicle. The assembly structure 10 is used for assembling the various components of the subway screen door 40 together to form a modular subway screen door 40. It can be understood that the subway screen door 40 mentioned in the present invention includes at least a pair of sliding doors and a fixed door or emergency door located on both sides of the pair of sliding doors; the transfer bracket 20 is used to store multiple subway screen doors 40 assembled on the assembly structure 10, so as to facilitate the storage and transportation of the subway screen doors 40 and reduce the difficulty of storage and transportation of the modular subway screen doors 40; the installation vehicle includes two moving modules 30 and a control unit (not shown in the figure). The two moving modules 30 are used to jointly move the subway screen door 4 located on the transfer bracket 20 0 is moved to the installation position 61 of the subway platform 60, so that the subway screen door 40 located on the transfer bracket 20 can be accurately placed on the installation position 61 of the subway platform 60, which is efficient and saves manpower. At the same time, the moving module 30 can also be used as an anti-dumping structure when installing the subway screen door 40. After the subway screen door 40 is moved to the installation position 61, the subway screen door 40 can be reliably limited to prevent it from tipping over, so that the subway screen door 40 remains in the installed state, which is convenient for operators to fix the subway screen door 40 located on the installation position 61; the two moving modules 30 are both electrically connected to the control unit to realize the linkage control of the two moving modules 30 and automatically perform balance calibration on the subway screen door 40, so that the subway screen door 40 can be accurately placed on the installation position 61 of the subway platform 60.

[0058] The subway screen door 40 installation equipment of the present invention can realize the modular assembly of the subway screen door 40, the integrated storage and transportation of the modular subway screen door 40, and the installation of the modular subway screen door 40 through the integrated assembly structure 10, the transfer bracket 20 and the installation vehicle. The installation of the modular subway screen door 40 can reduce the on-site installation time by 70%-80%. The installation time of a subway platform 60 can be shortened to three days, which greatly reduces the on-site installation cycle. In addition, the modular assembly of the subway screen door 40 can be completed in the factory, which can greatly reduce the on-site material management cost and is less likely to cause the problem of lost parts, making the assembly of the subway screen door 40 more efficient.

[0059] In this embodiment, the assembly structure 10 is used to assemble the subway screen door 40 in the vertical position when installed in the installation position 61; the transfer bracket 20 is used to store the subway screen door 40 in the vertical position when installed in the installation position 61. Thus, after assembly is completed, the subway screen door 40 can be directly hoisted and stored in the vertical position on the transfer bracket 20 using lifting equipment. Thereafter, the transfer bracket 20 containing the subway screen door 40 can be transferred to the subway platform 60 using lifting equipment. The transfer module 30 can then be used to directly move the subway screen door 40 to the installation position 61 for installation, eliminating the need to reposition the subway screen door 40. This improves the installation efficiency of the modular subway screen door 40.

[0060] Continue to see Figure 1 and Figure 2 The subway screen door 40 installation equipment also includes a railcar 50. The railcar 50 is used to cooperate with the subway track 70 and can be moved on the subway track 70 under the action of an external force (such as a tractor). The installation vehicle is placed on the railcar 50. This facilitates the continuous installation of the subway screen door 40. At the same time, because the subway screen door 40 is moved and installed on the side of the subway track 70, it can avoid occupying the space on the side of the subway platform 60 and will not be affected by the construction environment of the subway platform 60 (for example, when the subway platform 60 is being laid or the ceiling is being suspended). The movement and installation of the subway screen door 40 is more efficient, which helps to shorten the construction period of the subway platform 60.

[0061] See also Figure 3-Figure 8 In this embodiment, the assembly structure 10 includes a supporting structure 11 and a transfer structure 12. The supporting structure 11 and the transfer structure 12 enclose an assembly space for assembling the subway screen door 40. The supporting structure 11 is used to support the subway screen door 40. One side of the transfer structure 12 is used to be detachably connected to the subway screen door 40. The transfer structure 12 and the supporting structure 11 jointly define the position of the subway screen door 40. The other side of the transfer structure 12 is used to be connected to the lifting equipment so that the assembled subway screen door 40 can be moved out of the assembly space.

[0062] The support structure 11 and the transfer structure 12 work together to limit the position of the subway screen door 40, so that the subway screen door 40 can be quickly assembled in the assembly space. Since the transfer structure 12 and the subway screen door 40 are detachably connected, the disassembly and assembly between the transfer structure 12 and the subway screen door 40 can be facilitated, and the assembly is more convenient and the assembly efficiency is high. In addition, since the transfer structure 12 can be used to connect with the lifting equipment, it is more convenient to move the subway screen door 40. After the subway screen door 40 is assembled, the lifting equipment can be used to move the subway screen door 40 and the transfer structure 12 away from the assembly space, and then the lifting equipment can be used to move the transfer structure 12 to the original position.

[0063] In this embodiment, the assembly space is used for assembling the subway platform door 40 in a vertical state to form a modular subway platform door 40 placed in a vertical manner.

[0064] See also Figure 1 as well as Figure 7 In this embodiment, the support structure 11 includes a support crossbeam 111 and two support vertical beams 112 spaced apart from the support crossbeam 111. The support crossbeam 111 is arranged in a transverse direction and is used to support the subway screen door 40. The support vertical beams 112 abut against the transfer structure 12 to support the transfer structure 12, facilitating the positioning of the transfer structure 12, thereby facilitating the assembly of the subway screen door 40 and improving the assembly accuracy and efficiency of the subway screen door 40. Of course, in other embodiments, more than two support vertical beams 112 may be provided at each end of the support crossbeam 111, with adjacent support vertical beams 112 located at the ends of the support crossbeam 111 being close to each other.

[0065] Of course, in other embodiments, the support structure 11 may include a support beam 111 , that is, no support beam 112 is provided to support the transfer structure 12 .

[0066] See also Figure 7 and Figure 8 In this embodiment, the support beam 112 is provided with a plug-in slot 1121, and the transfer structure 12 is provided with a connector 124 that plugs into and mates with the plug-in slot 1121. The cooperation between the connector 124 and the plug-in slot 1121 prevents the transfer structure 12 from moving forward and backward, as well as left and right. This improves the positioning accuracy of the transfer structure 12, thereby further improving the assembly accuracy and efficiency of the subway screen door 40. Of course, in other embodiments, the support beam 112 may be provided with a connector 124, and the transfer structure 12 may be provided with a plug-in slot 1121 that mates with the connector 124, which can also achieve reliable positioning of the transfer structure 12.

[0067] Continue to see Figure 8The connector 124 includes a connecting portion 1241 and a plurality of positioning portions 1242. The connecting portion 1241 includes a first connecting section and a second connecting section connected in sequence from top to bottom. The first connecting section is closer to the transfer structure 12 than the second connecting section. The positioning portions 1242 are arranged on the side wall of the first connecting section. The plurality of positioning portions 1242 are spaced apart around the center line of the first connecting section. The side walls of the positioning portions 1242 are in clearance fit with the slot walls of the insertion slot 1121. Thus, when the connector 124 approaches the insertion slot 1121, the second connecting section that is not in contact with the slot walls of the insertion slot 1121 is first extended into the insertion slot 1121, and then the positioning portions 1242 are in clearance fit with the insertion slot 1121. The contact area between the connector 124 and the insertion slot 1121 is small, and the connector 124 and the insertion slot 1121 can be quickly engaged and disengaged, thereby achieving higher efficiency. Of course, in other embodiments, when the connector 124 is disposed on the supporting vertical beam 112 , the first connecting section is closer to the supporting vertical beam 112 than the second connecting section.

[0068] Continue to see Figure 8 In this embodiment, an inclined guide structure 12421 is provided at one end of the positioning portion 1242 close to the second connecting section, which serves to guide the positioning portion 1242 to facilitate the engagement and disengagement between the connector 124 and the connector slot 1121, thereby further improving efficiency.

[0069] See also Figure 3 and Figure 7 In this embodiment, the support structure 11 also includes two reinforcing oblique beams 113 arranged obliquely relative to the supporting vertical beam 112. One end of the reinforcing oblique beam 113 is connected to the supporting vertical beam 112, and the other end of the reinforcing oblique beam 113 is used to connect to the ground. This is beneficial to increase the structural strength of the supporting vertical beam 112, so that it can more stably support the transfer structure 12, thereby helping to improve the positioning accuracy of the transfer structure 12.

[0070] In this embodiment, the two reinforcement beams 113 are respectively connected to different sides of each support vertical beam 112, and the structural strength of the support vertical beam 112 is higher. Of course, in other embodiments, each support vertical beam 112 can be configured with one or more reinforcement beams 113.

[0071] In this embodiment, a plurality of first positioning structures 114 are provided on the supporting beam 111, and the plurality of first positioning structures 114 are arranged at lateral intervals along the supporting beam 111. The first positioning structures 114 are used to cooperate with the base on the bottom of the subway screen door 40, so as to position the subway screen door 40. At the same time, the first positioning structure 114 and the transfer structure 12 are used to jointly define the position of the subway screen door 40, which makes it more convenient to assemble the subway screen door 40, thereby improving the assembly efficiency and assembly accuracy of the subway screen door 40.

[0072] See also Figure 4 and Figure 5 Specifically, the first positioning structure 114 is provided with a first positioning groove 1141 or a positioning protrusion 1142, which is used to be plugged into and cooperated with the base on the bottom of the subway screen door 40. The first positioning groove 1141 or the positioning protrusion 1142 cooperates with the base of the subway screen door 40 to limit the left and right and front and back directions of the subway screen door 40 to prevent the subway screen door 40 from swinging. The support structure 11 and the transfer structure 12 jointly limit the position of the subway screen door 40, which can further improve the assembly efficiency and assembly accuracy of the subway screen door 40.

[0073] In this embodiment, the two first positioning structures 114 located at both ends of the supporting beam 111 are provided with first positioning grooves 1141. The two first positioning grooves 1141 are both provided with top openings and side openings. The side openings of the two first positioning grooves 1141 are opposite to each other. The first positioning structure 114 located between the two ends of the supporting beam 111 is provided with a positioning protrusion 1142. In this way, it is more convenient to insert the corresponding components of the subway screen door 40 and it is beneficial to improve the positioning accuracy of the subway screen door 40.

[0074] See Figure 4 The first base 41 of the subway screen door 40 of the present invention is inserted into the first positioning groove 1141, see Figure 5 The slot on the second base 42 of the subway screen door 40 of the present invention is plugged into the positioning protrusion 1142 .

[0075] See also Figure 3 as well as Figure 7 In this embodiment, the transfer structure 12 is located above the supporting structure 11. The transfer structure 12 includes a transfer beam 121, a first connecting structure 122 and a second connecting structure 123. The transfer beam 121 is opposite to the supporting beam 111. The first connecting structure 122 is arranged on one side of the transfer beam 121, and the second connecting structure 123 is arranged on the other side of the transfer beam 121. The first connecting structure 122 is used for detachable connection with the top of the subway screen door 40, and the second connecting structure 123 is used for connection with the lifting equipment.

[0076] See also Figure 6In this embodiment, the first connecting structure 122 includes a connecting beam 1221 and a connecting plate 1222. The connecting beam 1221 is fixedly connected to the transfer beam 121 and the connecting plate 1222. The connecting plate 1222 is protruded relative to the connecting beam 1221 and forms a protrusion. A connecting piece for detachable connection with the subway screen door 40 is provided on the protrusion. In this way, since the connecting piece detachably connected to the subway screen door 40 is provided on the protrusion protruding from the connecting beam 1221, it is more convenient to operate the connection and disconnection between the connecting piece and the subway screen door 40, which is conducive to improving the disassembly and assembly efficiency between the two.

[0077] Specifically, in this embodiment, the connecting member is a bolt, and the protruding portion is provided with a connecting hole 12221. The end of the bolt passes through the connecting hole 12221 and is threadedly connected to the threaded hole on the subway screen door 40. In this way, a detachable connection between the transfer structure 12 and the subway screen door 40 is achieved. At the same time, the connection between the transfer structure 12 and the subway screen door 40 is highly reliable, which helps to improve the assembly efficiency and assembly accuracy of the subway screen door 40. At the same time, the high reliability of the connection between the transfer structure 12 and the subway screen door 40 can help to improve the safety of the subway screen door 40 during the movement process. Of course, in other embodiments, the connecting member can be specifically a snap fastener, which snaps into engagement with a snap position on the subway screen door 40, and can also achieve a detachable connection between the transfer structure 12 and the subway screen door 40.

[0078] In this embodiment, a hanging buckle 1231 for connecting to a lifting device is provided on the second connecting structure 123 to facilitate quick connection and disconnection between the lifting device and the transfer structure 12 .

[0079] See also Figures 9-18 In this embodiment, the transfer bracket 20 includes a bracket body, which is provided with a plurality of storage positions. The storage positions are used to vertically place the subway screen door 40. A second positioning structure 24 is provided at the bottom of the storage position. The second positioning structure 24 is used to cooperate with the base on the bottom of the subway screen door 40 to position the subway screen door 40. Limiting structures 25 are provided on the opposite sides of the storage position. The limiting structures 25 located on both sides of the storage position are respectively used to connect with the two sides of the subway screen door 40 to limit the position of the subway screen door 40.

[0080] By utilizing the second positioning structure 24 at the bottom of the storage position and the limiting structures 25 at both sides of the storage position to jointly define the position of the subway screen door 40, the subway screen door 40 can be fixedly placed in the storage position in a set state. The structure is stable, which can effectively prevent the subway screen door 40 from being damaged, and reduces the difficulty of storing and transporting the subway screen door 40; because the storage position can allow the subway screen door 40 to be placed vertically, it is more convenient to load and unload the subway screen door 40, and the loading and unloading efficiency of the subway screen door 40 is higher; because there are multiple storage positions, the transfer bracket 20 can support multiple subway screen doors 40 at the same time, has a large capacity, can realize the integrated storage and transportation of the subway screen door 40, and is conducive to reducing costs.

[0081] Continue to see Figure 9 as well as Figure 12 In this embodiment, the bracket body includes a base frame 21 and a guardrail arranged on the base frame 21. The base frame 21 and the guardrail together form a storage position. The second positioning structure 24 is arranged on the base frame 21, and the limiting structure 25 is arranged on the guardrail. The setting of the guardrail can play a good protective role.

[0082] See also Figure 12 In this embodiment, the guardrail specifically includes a first side frame 22 and a second side frame. The outer contour of the base frame 21 is rectangular. Two first side frames 22 and two second side frames are provided. The two first side frames 22 are parallel and the two first side frames 22 are respectively vertically fixed on two opposite sides of the base frame 21. The limiting structure 25 is provided on the first side frame 22. The second side frame is located between the two first side frames 22. The two second side frames are parallel and the two second side frames are respectively provided on the other opposite sides of the base frame 21, and the second side frames are detachably connected to the first side frames 22 and the base frame 21. In this way, a bracket body structure with a stable and reliable structure can be formed, and the second side frame can be removed from the bracket body. When loading the subway screen door 40, the subway screen door 40 can be placed from top to bottom in the storage position through lifting equipment. After that, the transfer bracket 20 loaded with the subway screen door 40 is transferred to the subway platform 60, the second side frame can be removed, and then the moving module 30 can be used to move the subway screen door 40 out from the side of the bracket body, which makes the installation of the subway screen door 40 more convenient.

[0083] Continue to see Figure 12More specifically, the base frame 21 includes a first bottom cross beam 211, a second bottom cross beam 212 and a third bottom cross beam 213. Two first bottom cross beams 211 are provided, and the two first bottom cross beams 211 are spaced apart. Two pairs of second bottom cross beams 212 are provided, and the second bottom cross beams 212 are provided between the two first bottom cross beams 211, and the second bottom cross beams 212 are perpendicular to the first bottom cross beams 211. A plurality of third bottom cross beams 213 are provided between the two second bottom cross beams 212 in each pair of second bottom cross beams 212, and adjacent third bottom cross beams 213 are spaced apart. In this way, a base frame 21 structure with a stable structure and material saving is formed, which is conducive to reducing the cost of the transfer bracket 20.

[0084] Specifically, the first side frame 22 includes a first side cross beam 221 and a vertical beam 222. There are two vertical beams 222. The limiting structure 25 is arranged on the first side cross beam 221. The first side cross beam 221 is parallel to the base frame 21. The vertical beam 222 is arranged between the end of the first side cross beam 221 and the end of the base frame 21, and the two ends of the vertical beam 222 are fixedly connected to the end of the first side cross beam 221 and the end of the base frame 21 respectively to improve the connection stability between the first side frame 22 and the base frame 21.

[0085] Specifically, the second side frame includes a second side crossbeam 231 and an oblique beam 232. The ends of the second side crossbeam 231 are detachably connected to the ends of the adjacent vertical beams 222. Two oblique beams 232 are provided, and the ends of each oblique beam 232 are detachably connected to the vertical beams 222 and the first bottom crossbeam 211. This can strengthen the connection stability between the base frame 21, the first side frame 22, and the second side frame. At the same time, it saves materials, helps reduce costs, and reduces the overall weight of the transfer bracket 20, making it more convenient to move. Of course, in other embodiments, the second side frame can also be specifically a rectangular frame structure.

[0086] In this embodiment, the second side cross beam 231 and the vertical beam 222, as well as the oblique beam 232, the vertical beam 222, and the first bottom cross beam 211 can be connected together by fastening bolts 244, which allows for both detachable assembly and secure connection. Of course, in other embodiments, the second side cross beam 231 and the vertical beam 222, as well as the oblique beam 232, the vertical beam 222, and the first bottom cross beam 211 can be connected together by snap fastening.

[0087] In this embodiment, each storage position is provided with a plurality of second positioning structures 24, which are arranged at intervals along the lateral direction of the bracket body, thereby improving the positioning accuracy of the subway screen door 40 and reducing costs.

[0088] See also Figure 10 、 Figure 11 、 Figure 13 、 Figure 14 、 Figure 17 as well as Figure 18 In this embodiment, the second positioning structure 24 includes a positioning base 241 and a pressure plate 242; the positioning base 241 is fixedly arranged on the bracket body, and the positioning base 241 is provided with a second positioning groove 2413 for cooperating with the base on the subway screen door 40; the pressure plate 242 is detachably arranged on the positioning base 241. When the second positioning groove 2413 is engaged with the base on the subway screen door 40, the pressure plate 242 is fixed to the positioning base 241, and the pressure plate 242 is abutted against the top surface of the base on the subway screen door 40. The pressure plate 242 and the positioning base 241 jointly define the position of the base on the subway screen door 40. For details, see Figure 10 as well as Figure 11 The second positioning groove 2413 cooperates with the base on the subway screen door 40 to limit the base of the subway screen door 40 in the front-back and left-right directions, and the pressure plate 242 and the bracket body are used to limit the base on the subway screen door 40 in the up-down direction. Combined with the anti-dumping effect of the limiting structure 25 on the subway screen door 40, the subway screen door 40 can be securely placed on the bracket body.

[0089] Continue to see Figure 17 as well as Figure 18 At least one pair of slots 2414 is provided on the positioning base 241, and the two ends of the pressure plate 242 are respectively inserted into the two slots 2414, so as to realize quick disassembly and assembly between the pressure plate 242 and the positioning base 241, thereby improving the loading and unloading efficiency of the subway screen door 40.

[0090] Continue to see Figure 17 as well as Figure 18 In this embodiment, the width of the slot 2414 gradually increases from the back to the front, and the pressure plate 242 is provided with a wedge-shaped portion 2421 that is adapted to the shape of the slot 2414. During the process of inserting the pressure plate 242 into the slot 2414, the wedge-shaped portion 2421 and the slot 2414 are reliably wedged, thereby improving the connection reliability between the pressure plate 242 and the positioning base 241.

[0091] See also Figure 13 as well as Figure 17In this embodiment, the positioning base 241 includes a first positioning side plate 2411a and a second positioning side plate 2412a; the first positioning side plate 2411a is provided with two pieces, the two first positioning side plates 2411a are arranged opposite to each other, and each first positioning side plate 2411a is provided with a slot 2414; the second positioning side plate 2412a is arranged between the two first positioning side plates 2411a; the two first positioning side plates 2411a and the second positioning side plates 2412a are enclosed to form a second positioning groove 2413. At this time, the first base 41 on the subway screen door 40 is inserted into the second positioning groove 2413, and the first bottom plate on the first base 41 is arranged in the space enclosed by the bracket body, the first positioning side plate 2411a and the pressure plate 242; the second positioning structure 24 also includes a fastening plate 243, a fastening bolt 244 and a fastening nut 245, see Figure 13 The fastening plate 243 is arranged on the outer side of the second positioning side plate 2412a and abuts against the second positioning side plate 2412a. Both ends of the fastening plate 243 are provided with a first through-hole 2211, and both ends of the pressure plate 242 are also provided with a second through-hole. The number of fastening bolts 244 and fastening nuts 245 is the same as the number of the first through-hole 2211 or the second through-hole. The threaded end of each fastening bolt 244 passes through the first through-hole 2211 and the second through-hole in turn and is connected with a fastening nut 245, and the head of the fastening bolt 244 abuts against the second positioning side plate 2412a, and the fastening nut 245 abuts against the pressure plate 242, so as to more reliably lock the pressure plate 242 on the positioning base 241, thereby realizing reliable positioning of the subway screen door 40.

[0092] Of course, the specific structure of the second positioning structure 24 can also adopt the following scheme: Figure 14 as well as Figure 18The positioning base 241 includes a third positioning side plate 2411b and a positioning connecting plate 2412b. The third positioning side plate 2411b is connected to the bracket body. The third positioning side plate 2411b is provided with two pieces. The two third positioning side plates 2411b are arranged opposite to each other. The positioning connecting plate 2412b is arranged between the two third positioning side plates 2411b. The two third positioning side plates 2411b are both provided with a slot 2414. The positioning connecting plate 2412b is used to cooperate with the slot on the base on the subway screen door 40. The third positioning side plate 2411b and the positioning connecting plate 2412b are enclosed to form a second positioning groove 2413. At this time, the second base 42 on the subway screen door 40 is inserted into the second positioning groove 2413, and the slot on the second base 42 cooperates with the positioning connecting plate 2412b, and the second base 4 2 is arranged in a space enclosed by the bracket body, the third positioning side plate 2411b and the pressure plate 242; a slot 2414 is provided at both ends of each third positioning side plate 2411b, and the opening directions of the two slots 2414 on the same third positioning side plate 2411b are opposite, and two pressure plates 242 are provided, and the two ends of each pressure plate 242 are respectively inserted into the adjacent slots 2414 on the two pressure plates 242; the second positioning structure 24 also includes two fastening bolts 244 and two fastening nuts 245, and each pressure plate 242 is provided with a through hole at both ends, and the threaded end of each fastening bolt 244 passes through the adjacent through holes on the two pressure plates 242 and is connected with a fastening nut 245 to more reliably lock the pressure plate 242 on the positioning base 241, thereby realizing reliable positioning of the subway screen door 40.

[0093] Of course, in other embodiments, the above-mentioned second positioning structure 24 may include a driving device and a pair of positioning arms. The driving device is provided with two output ends, and the pair of positioning arms are respectively connected to the two output ends. The driving device is used to drive the pair of positioning arms to approach each other so that the pair of positioning arms jointly clamp the subway screen door 40. The driving device is used to drive the pair of positioning arms away from each other so that the pair of positioning arms release the subway screen door 40. The operation is automated and positioning is more convenient.

[0094] In this embodiment, the two limiting structures 25 on either side of the storage position are arranged opposite each other, which helps to improve the connection stability between the limiting structures 25 and the subway screen door 40, so that the subway screen door 40 can be placed more firmly in the storage position. Of course, in other embodiments, the two limiting structures 25 on either side of the storage position can be staggered.

[0095] See also Figure 9 、 Figure 12 as well as Figure 15In this embodiment, the limiting structure 25 is detachably mounted on the bracket body. Thus, before placing the subway screen door 40 in the storage position, the limiting structure 25 can be removed from the bracket body to leave both sides of the storage position unobstructed, thereby making it more convenient to load the subway screen door 40. After the subway screen door 40 is loaded in the storage position, the limiting structure 25 is mounted on the bracket body and connected to the subway screen door 40 to limit the position of the subway screen door 40.

[0096] like Figure 15 As well as Figure 16 As shown, in this embodiment, the limiting structure 25 includes a base 251, a limiting rod 252 and a first locking nut 253. The limiting rod 252 is fixedly set on the base 251, and the end of the limiting rod 252 is provided with a first threaded structure. The bracket body is provided with a first through-hole 2211 (that is, the first side beam 221 is provided with a first through-hole 2211). During installation, the base 251 is abutted against the outer wall of the bracket body, and the limiting rod 252 passes through the first through-hole 2211 and the hole on the subway screen door 40 in sequence. The first locking nut 253 cooperates with the first threaded structure passing through the hole on the subway screen door 40, and the first locking nut 253 is used to abut against the subway screen door 40. In this way, the subway screen door 40 can be fixed in the set position, thereby preventing the subway screen door 40 from tipping over. The structure is stable and reliable, and the cost is low.

[0097] In this embodiment, the limiting structure 25 also includes a connecting rod 254 and a second locking nut (not shown in the figure). The connecting rod 254 is arranged on the base 251, and a second threaded structure is provided on the connecting rod 254. A second through-hole is provided on the bracket body (that is, a second through-hole is provided on the second top crossbeam). During installation, the connecting rod 254 passes through the second through-hole, and the second locking nut is connected to the second threaded structure passing through the second through-hole, and the second locking nut is abutted against the inner side wall of the bracket body. In this way, the connection between the limiting structure 25 and the bracket body can be made more stable, thereby reinforcing the subway screen door 40 and placing the subway screen door 40 more firmly in the storage position.

[0098] Of course, in other embodiments, the above-mentioned limiting structure 25 may include a driving device and a limiting arm. The driving device is fixed to the bracket body, and the limiting arm is connected to the output end of the driving device. The driving device drives the limiting arm to extend and retract, so that the limiting arm can be connected to or disconnected from the subway screen door 40. The operation is automated, which is more convenient and more efficient.

[0099] See also Figures 19-24In this embodiment, the transport module 30 includes a base 31, a first transverse drive mechanism 32, a lifting drive mechanism 33, a second transverse drive mechanism 34 and a grabbing arm 35; the first transverse drive mechanism 32 is arranged on the base 31; the lifting drive mechanism 33 is arranged on the first transverse drive mechanism 32; the second transverse drive mechanism 34 is arranged on the lifting drive mechanism 33; the grabbing arm 35 is arranged on the second transverse drive mechanism 34; the first transverse drive mechanism 32 is used to drive the lifting drive mechanism 33 to move along the first transverse direction close to or away from the subway screen door 40, so that the grabbing arm 35 can grab the subway screen door 40 or make the grabbing arm 35 grab the subway screen door 40. The picking arm 35 is disconnected from the subway screen door 40; the lifting drive mechanism 33 is used to drive the second transverse driving mechanism 34 to perform a lifting movement in the vertical direction, so that the grabbing arm 35 can lift the subway screen door 40 or the grabbing arm 35 can lower the subway screen door 40; the second transverse driving mechanism 34 is used to drive the grabbing arm 35 to move along a second transverse direction close to or away from the installation position 61 of the subway platform 60, and the second transverse direction is perpendicular to the first transverse direction, so that the grabbing arm 35 can move the subway screen door 40 to the installation position 61 of the subway platform 60 or reset the grabbing arm 35 from the installation position 61 of the subway platform 60 to a position close to the uninstalled subway screen door 40.

[0100] By utilizing the linkage between the first transverse driving mechanism 32, the lifting driving mechanism 33 and the second transverse driving mechanism 34 in the two moving modules 30, the grabbing arm 35 is jointly acted on the corresponding grabbing arm 35, so that the grabbing arm 35 can grab the subway screen door 40 and move the subway screen door 40 to the installation position 61 of the subway platform 60, so that the subway screen door 40 can be accurately positioned on the installation position 61. At the same time, the moving module 30 can also be used as an anti-dumping structure when installing the subway screen door 40. After the subway screen door 40 is moved to the installation position 61, the subway screen door 40 can be reliably limited to prevent it from tipping over, so that the subway screen door 40 remains in the installed state, which is convenient for the operator to fix the subway screen door 40 on the installation position 61. Afterwards, the grabbing arm 35 is reset to a position close to the uninstalled subway screen door 40. In summary, the subway screen door 40 installation vehicle can accurately place the subway screen door 40 on the installation position 61, which is efficient and saves manpower.

[0101] See also Figure 22In this embodiment, the first transverse driving mechanism 32 includes a first transverse driving motor 321, a first transverse screw 322 nut pair and a first transverse linear guide pair; the first transverse driving motor 321, the first transverse screw 322 nut pair and the first transverse linear guide pair are all fixed on the machine base 31; the first transverse screw 322 nut pair and the first transverse linear guide pair are both arranged along the first transverse direction; the first transverse screw 322 in the first transverse screw 322 nut pair is drive-connected to the first transverse driving motor 321; the first transverse slider 325 in the first transverse linear guide pair is connected to the first transverse nut 323 in the first transverse screw 322 nut pair; the lifting driving mechanism 33 is arranged on the first transverse slider 325 or the first transverse nut 323. In this way, the first transverse drive motor 321 drives the first transverse screw 322 to rotate, thereby driving the first transverse nut 323 to move on the first transverse screw 322, and at the same time, driving the first transverse slider 325 to move on the first transverse guide rail 324, thereby driving the first lifting drive mechanism 33, the second transverse drive mechanism 34 and the grabbing arm 35 to move synchronously along the first transverse direction, so that the grabbing arm 35 can grab the subway screen door 40, the structure is more stable, and the operation is smoother.

[0102] Continue to see Figure 22 In this embodiment, two pairs of first transverse screw 322 nut pairs and first transverse linear guide pairs are provided, and the two pairs of first transverse screw 322 nut pairs are separated by a distance along the second transverse direction, and the two pairs of first transverse linear guide pairs are separated by a distance along the second transverse direction; the first transverse drive mechanism 32 also includes a synchronous transmission mechanism, and the synchronous transmission mechanism includes a driving wheel 326, a driven wheel 327 and a transmission belt 328. The driving wheel 326 is arranged on the first transverse screw 322 connected to the first transverse drive motor 321, and the driven wheel 327 is arranged on the other first transverse screw 322. The transmission belt 328 is movably wound between the driving wheel 326 and the driven wheel 327; the lifting drive mechanism 33 is arranged between the two first transverse sliders 325 or the lifting drive mechanism 33 is arranged between the two first transverse nuts 323. In this way, the structural stability can be further improved and the operation can be made smoother. At the same time, by setting up a synchronous transmission mechanism, only one motor is needed to drive the two pairs of first transverse screws 322 nut pairs in linkage, which is conducive to reducing costs.

[0103] In this embodiment, a first transverse hand crank (not shown in the figure) or a first transverse turntable (not shown in the figure) is fixedly provided on the output shaft of the first transverse drive motor 321. The first transverse hand crank or the first transverse turntable can drive the first transverse screw 322 to rotate. By manually rotating the first transverse hand crank or the first transverse turntable, the lifting drive mechanism 33, the second transverse drive mechanism 34 and the grabbing arm 35 can be driven to move along the first transverse direction. The setting of the first transverse hand crank or the first transverse turntable can enable the first transverse drive mechanism 32 to switch between automatic operation and manual operation, ensuring that the subway screen door 40 can still be moved normally during a power outage, playing a temporary emergency role and preventing delays in the construction period.

[0104] See also Figure 22 and Figure 23 The lifting drive mechanism 33 includes a first connecting seat 331, a lifting drive motor 332 and a lifting screw 335 nut pair. The first connecting seat 331 is fixedly set on the top surface of the two first transverse sliding sliders 325. The lifting screw 335 nut pair is set vertically. The lifting screw 335 in the lifting screw 335 nut pair is connected to the lifting drive motor 332. The second transverse driving mechanism 34 is connected to the lifting nut 336 in the lifting screw 335 nut pair. The lifting motor drives the lifting screw 335 to rotate and drives the lifting nut 336 to move vertically, thereby driving the second transverse driving mechanism 34 to perform lifting and lowering movements vertically. The structure is stable and the operation is smoother.

[0105] Continue to see Figure 22 and Figure 23 , there are two pairs of lifting screw 335 nut pairs, and the two pairs of lifting screw 335 nut pairs are separated by a distance along the second horizontal direction; the lifting drive mechanism 33 also includes two groups of turbine 334 worm 333 structures; the worm 333 in one group of turbine 334 worm 333 structures is connected to the lifting drive motor 332, and the turbine 334 in the turbine 334 worm 333 structure is connected to a lifting screw 335 close to the lifting drive motor 332; the worm 333 in the other group of turbine 334 worm 333 structures is connected to the other worm 333 through a transmission shaft 337, and the turbine 334 in the group of turbine 334 worm 333 structures is connected to the other lifting screw 335 away from the lifting drive motor 332; the second transverse movement drive mechanism 34 is arranged on two lifting nuts 336. In this way, the structure is more stable and the operation is smoother. At the same time, because a transmission shaft 337 is provided, only one motor is needed to drive the two pairs of lifting screws 335 and nut pairs in linkage, which is conducive to reducing costs. In addition, because a turbine 334 and a worm 333 structure are provided, the installation of the lifting drive mechanism 33 is more convenient, making the overall structure more compact.

[0106] In this embodiment, a lifting hand crank 338 or a lifting turntable is provided at the end of the transmission shaft 337 away from the lifting drive motor 332. The lifting hand crank 338 or the lifting turntable can drive the transmission shaft 337 to rotate. By manually rotating the lifting hand crank 338 or the lifting turntable, the second transverse drive mechanism 34 and the grab arm 35 can be driven to move vertically. The provision of the lifting hand crank 338 or the lifting turntable enables the lifting drive mechanism 33 to switch between automatic and manual operation, ensuring that the subway screen door 40 can still be moved normally during a power outage, serving as a temporary emergency measure and preventing construction delays. In addition, because the lifting hand crank 338 or the lifting turntable is provided at the end of the transmission shaft 337 away from the lifting drive motor 332, there is a larger operating space, making it more convenient to operate the lifting hand crank 338 or the lifting turntable.

[0107] Continue to see Figure 23 Two pairs of lifting guide linear guide rails 36 are mounted on the first connecting seat 331. Both pairs of lifting guide linear guide rails 36 are arranged vertically and spaced apart along the second lateral direction. A second lifting guide rail 361 of the lifting guide linear guide rails 36 is fixedly mounted on the first connecting seat 331. The two ends of the second transverse drive mechanism 34 are respectively connected to the lifting guide sliders 362 of the two lifting guide linear guide rails 36. This provides a guide for the second transverse drive mechanism 34 and enhances structural stability, making the second transverse drive mechanism 34 move more smoothly and operate more stably.

[0108] See also Figure 22 and Figure 24 In this embodiment, the second transverse driving mechanism 34 includes a second connecting seat 341, a second transverse driving motor 342, a second transverse screw 343 nut pair, a second transverse linear guide pair, a third transverse driving motor 347, a third transverse screw 348 nut pair and a third transverse linear guide pair; the two ends of the second connecting seat 341 are respectively fixed to the two lifting guide sliders 362 mentioned above, and the part between the two ends of the second connecting seat 341 is fixed to the lifting nut 336; the second transverse screw 343 nut pair, the second transverse linear guide pair, the third transverse screw 348 nut pair and the third transverse linear guide pair are all arranged along the second transverse direction; the second transverse linear guide pair is fixed on the second connecting seat 341.

[0109] The second transverse driving motor 342 is fixedly arranged on the bottom of the second transverse guide rail 345 in the second transverse linear guide pair; a first accommodating groove is arranged on the second transverse guide rail 345; the second transverse screw 343 nut pair is arranged in the first accommodating groove, the second transverse screw 343 in the second transverse screw 343 nut pair is connected to the second transverse driving motor 342, and the second transverse nut 344 in the second transverse screw 343 nut pair is connected to the second transverse slider 346 in the second transverse linear guide pair.

[0110] The third transverse driving motor 347 is arranged on the top of the third transverse guide rail 3410 in the third transverse linear guide pair. The third transverse guide rail 3410 is arranged above the second transverse guide rail 345 and is connected to the second transverse slider 346, and the front end of the third transverse guide rail 3410 protrudes from the second transverse guide rail 345, so that the front end of the third transverse guide rail 3410 is closer to the installation position 61 of the subway platform 60 than the front end of the second transverse guide rail 345, ensuring sufficient stroke, so that the subway screen door 40 can be moved to the installation position 61; a second accommodating groove is provided on the third transverse guide rail 3410; the third transverse screw 348 nut pair is arranged in the second accommodating groove, the third transverse screw 348 in the third transverse screw 348 nut pair is connected to the third transverse driving motor 347, and the third transverse nut 349 in the third transverse screw 348 nut pair is connected to the third transverse slider 3420; the grabbing arm 35 is arranged on the third transverse module.

[0111] Because the second transverse driving mechanism 34 includes two standard transverse modules arranged along the second transverse direction, an overlapping stroke is achieved, ensuring that the stroke is sufficient, thereby ensuring that the subway screen door 40 can be moved to the installation position 61. Such a structural design is more conducive to reducing costs, and the structure is more stable and runs more smoothly.

[0112] Of course, in other embodiments, the second transverse drive mechanism 34 may also adopt a transverse module, in which the transverse screw nut pair and the transverse linear guide pair are manufactured in a customized manner, and the cost is higher than the structure using two standard transverse modules.

[0113] In this embodiment, a second transverse crank or a second transverse turntable is mounted on the output shaft of the second transverse drive motor 342, which drives the second transverse lead screw 343. A third transverse crank or a third transverse turntable is mounted on the output shaft of the third transverse drive motor 347, which drives the third transverse lead screw 348. This allows the second transverse drive mechanism 34 to switch between automated and manual operation, ensuring that the subway screen door 40 can be moved normally during a power outage, thus providing a temporary emergency response and preventing project delays.

[0114] Of course, in other embodiments, the first transverse driving mechanism 32, the lifting driving mechanism 33 and the second transverse driving mechanism 34 can all be replaced by linear driving mechanisms such as air cylinders and hydraulic cylinders.

[0115] See also Figure 21 The robotic arm is provided with a grabbing hook 351 for engaging with the subway screen door 40, so as to achieve a stable connection between the grabbing arm 35 and the subway screen door 40, making the movement safer.

[0116] In this embodiment, there are two rows of grabbing hooks 351 on each moving module 30. The two rows of grabbing hooks 351 are respectively arranged vertically, and the two rows of grabbing hooks 351 are separated by a spacing in the first horizontal direction. Each row of grabbing hooks 351 is provided with at least two grabbing hooks 351 arranged vertically spaced apart. In this way, the connection between the grabbing arm 35 and the subway screen door 40 is more stable, which is conducive to further improving the positioning accuracy of the subway screen door 40 and, at the same time, improving the safety of moving.

[0117] Continue to see Figure 21 The grabbing hook 351 is provided with a limiting groove 3511 that can be engaged with the side of the subway screen door 40. The opening of the limiting groove 3511 faces upward to facilitate the connection and disconnection between the grabbing hook 351 and the subway screen door 40. At the same time, the connection between the two is more reliable.

[0118] The present invention also discloses a method for installing a subway screen door 40, which uses the above-mentioned subway screen door 40 installation device to install the subway screen door 40, and includes the following steps:

[0119] The manufactured subway screen door 40 is assembled on the assembly structure 10 with its components to form a modular subway screen door 40. During assembly, the subway screen door 40 is assembled in a vertical position when installed at the installation position 61 of the subway platform 60 to facilitate the hoisting and installation of the modular subway screen door 40.

[0120] The subway screen door 40 assembled on the assembly structure 10 is transferred to the transfer bracket 20 for storage using a lifting device. The subway screen door 40 is stored on the transfer bracket 20 in a vertical state when installed at the installation position 61 of the subway platform 60, so as to facilitate the subsequent movement and installation of the subway screen door 40.

[0121] The transfer bracket 20 storing the subway screen door 40 is transferred to the subway platform 60 and moved between the two transfer modules 30. More specifically, the transfer bracket 20 storing the subway screen door 40 is first transferred to a transport vehicle using a lifting device. The subway screen door 40 is then transferred to the subway platform 60 by the transport vehicle. The transfer bracket 20 storing the subway screen door 40 is then transferred to a rail vehicle 50 pre-placed with two transfer modules 30 using a lifting device, and the transfer bracket 20 is positioned between the two transfer modules 30.

[0122] The two moving modules 30 are used to act on both sides of the subway platform screen door 40 located on the transfer bracket 20 respectively, and move the subway platform screen door 40 from the transfer bracket 20 to the installation position 61 of the subway platform 60.

[0123] The subway screen door 40 installation method of the present invention can realize the modular assembly of the subway screen door 40, the integrated storage and transportation of the modular subway screen door 40, and the installation of the modular subway screen door 40. The installation of the modular subway screen door 40 can reduce the on-site installation time by 70%-80%, and the installation time of a subway platform 60 can be shortened to three days, greatly reducing the on-site installation period. In addition, the modular assembly of the subway screen door 40 can be completed in the factory, which can greatly reduce the on-site material management cost and is less likely to cause the problem of lost parts, making the assembly of the subway screen door 40 more efficient. In addition, because the subway screen door 40 is moved and installed on the side of the subway track 70, it can avoid occupying the position on the side of the subway platform 60 and will not be affected by the construction environment of the subway platform 60 (for example, when the subway platform 60 is laying floors or ceilings), the movement and installation of the subway screen door 40 are more efficient, which is conducive to shortening the construction period of the subway platform 60.

[0124] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present invention shall fall within the scope of protection required by the present invention.
