Description

Technical Field

[0001] The utility model belongs to the technical field related to auxiliary installation equipment, and particularly relates to a transport device. Background Art

[0002] The platform screen doors and safety doors of rail transit platforms are the door bodies on subway platforms that protect the safety of passengers. At present, the platform doors of existing subway platforms are generally shipped in parts, then assembled into platform screen doors on site, and then the assembled platform screen doors are transported to the platform for installation. However, this installation method of shipping parts and assembling on site has problems such as slow installation speed, difficult on-site material management, on-site debugging, and unguaranteed product quality. With the development of the industry, a concept of modular installation is now proposed, which can achieve 5,000 debugging projects before leaving the factory, and only simple adjustments are required for acceptance when installed on the construction site.

[0003] Although the modular installation method solves the above-mentioned problems of scattered parts shipment and on-site assembly requiring on-site debugging, the modular installation method still has the problem of not being suitable for traditional transportation methods.

[0004] The traditional method of transportation is to manually carry the platform doors assembled on site to the platform for installation. However, since the overall length of the assembled modular full-height platform door is about 5 meters, the height is about 3 meters, and the overall weight is about 1 ton, the traditional manual transportation method can basically not achieve the transportation purpose. Therefore, it is necessary to arrange tower crane equipment on site for lifting and transportation, which results in the on-site installation of the entire modular full-height platform door not only having a long construction period but also high cost. Utility Model Content

[0005] In view of this, it is necessary to provide a transport device for solving the problem that traditional manual transport cannot transport the assembled shielding door module units.

[0006] A handling device, comprising a rail car and two sets of transfer machines, wherein a storage area for placing a platform shielding door module unit is formed on the rail car, the two sets of transfer machines are arranged on both sides of the storage area and are respectively connected to the rail car, and the rail car can drive the two sets of transfer machines and the platform shielding door module unit placed in the storage area to move in the X-axis direction;

[0007] Among them, the transfer machine includes a grabbing mechanism, an X-axis driving mechanism, a Y-axis driving mechanism and a Z-axis driving mechanism. The X-axis driving mechanism can drive the grabbing mechanism to move along the X-axis direction to drive the grabbing mechanism to grab the shielding door module unit in the storage area; the Y-axis driving mechanism can drive the X-axis driving mechanism and the grabbing mechanism to move along the Y-axis direction; the Z-axis driving mechanism can drive the Y-axis driving mechanism, the X-axis driving mechanism and the grabbing mechanism to move along the Z-axis direction.

[0008] It can be understood that the storage area of ​​the rail car is used to carry the shielding door module unit, and then the movement of the rail car in the X-axis direction is used to drive the shielding door unit to move along the X-axis direction. After the two sets of transfer machines cooperate with each other to grab the shielding door unit, the shielding door module unit is driven to move in the Y-axis and Z-axis directions to achieve the position adjustment of the shielding door module unit during on-site installation. This can meet the on-site use requirements for the installation of the shielding door module unit, so that the handling device can realize the transportation and on-site installation of the assembled shielding door module unit, which can facilitate the on-site installation of the shielding door module unit, shorten the construction period and reduce the cost; at the same time, the movement of the shielding door module unit in the X-axis direction is driven by the rail car, which can facilitate the movement of the shielding door module unit in the X-axis direction and simplify the structure of the handling device.

[0009] In one embodiment, the Y-axis driving mechanism includes a first Y-axis driving mechanism and a second Y-axis driving mechanism;

[0010] The transfer machine further includes a Y-axis base, a telescopic beam and an X-axis bracket, wherein the telescopic beam is slidably connected to the Y-axis base and the X-axis bracket in the Y-axis direction, respectively, the first Y-axis driving mechanism is used to drive the telescopic beam to move along the Y-axis direction on the Y-axis base, and the second Y-axis driving mechanism is used to drive the X-axis bracket to move along the Y-axis direction on the telescopic beam;

[0011] Wherein, the X-axis driving mechanism is installed on the X-axis bracket, and the Z-axis driving mechanism is used to drive the Y-axis base to move along the Z-axis direction.

[0012] It is understandable that the rail car needs to run on the track, and the stroke in the Y-axis direction (the direction perpendicular to the X-axis on the same horizontal plane) is large, so the first Y-axis drive mechanism and the second Y-axis drive mechanism are used to drive the X-axis drive mechanism and the grasping mechanism to move in two strokes on the Y-axis. This can increase the moving stroke of the shielding door module unit grasped by the grasping mechanism on the Y-axis when the transport device is working. In this way, it can be ensured that the shielding door module unit can be completely detached from the storage area of ​​the rail car to meet the use requirements of the on-site installation of the shielding door module unit, and by separately controlling the two strokes of the Y-axis, the safety of the equipment running on the track can be guaranteed while realizing the function.

[0013] In one embodiment, the first Y-axis driving mechanism includes a first Y-axis driving member, and the first Y-axis driving member drives the telescopic beam and the Y-axis base to have a relative displacement along the Y-axis direction through a first gear rack transmission mechanism;

[0014] And / or, the second Y-axis driving mechanism includes a second Y-axis driving member, and the second Y-axis driving member drives the X-axis bracket and the telescopic beam to have a relative displacement along the Y-axis direction through a second gear rack transmission mechanism.

[0015] It can be understood that the first gear rack transmission mechanism is used to realize the movement between the telescopic beam and the Y-axis base along the Y-axis direction, and the second gear rack transmission mechanism is used to realize the movement between the X-axis bracket and the telescopic beam along the Y-axis direction. In this way, the structure of the first Y-axis drive mechanism and the second Y-axis drive mechanism can be simplified, and the consistency of the travel direction when moving along the Y-axis direction can be ensured.

[0016] In one embodiment, the first gear rack transmission mechanism includes a first driving gear and a first Y-axis rack, the first driving gear is synchronously connected to the first Y-axis driving member and meshes with the first Y-axis rack, wherein the first Y-axis driving member is fixedly connected to the Y-axis base, and the first Y-axis rack is fixedly connected to the telescopic beam;

[0017] And / or, the second gear rack transmission mechanism includes a second driving gear and a second Y-axis rack, the second driving gear is synchronously connected to the second Y-axis driving member and meshes with the second Y-axis rack, wherein the second Y-axis driving member is fixedly connected to the X-axis bracket, and the second Y-axis rack is fixedly connected to the telescopic beam.

[0018] In one embodiment, the gripping mechanism includes a support plate and a positioning member, and the positioning member is fixedly connected to the support plate;

[0019] Wherein, a positioning hole (220) matching the positioning piece is provided on the shielding door module unit, and the positioning piece can form a plug-in fit with at least a portion of the positioning hole under the drive of at least one of the X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism, and can form a locking fit with at least a portion of the positioning hole under the drive of at least one of the X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism, so as to capture the shielding door module unit.

[0020] In one of the embodiments, a positioning hole matching the positioning member is formed on the shielding door module unit, and the positioning member can be engaged and locked with the positioning hole under the drive of the support plate to capture the shielding door module unit.

[0021] It can be understood that, by utilizing the structural characteristics of the positioning hole on the shielding door module unit, after the positioning piece on the grasping mechanism is inserted into the positioning hole on the shielding door module unit in the X-axis direction, the grasping mechanism is driven to move in the Z-axis direction through the Z-axis driving mechanism, and the snap-fit ​​locking between the positioning piece and the positioning hole can be achieved. This not only simplifies the structure of the grasping mechanism and facilitates the grasping of the shielding door module unit by the grasping mechanism, but also improves the stability of the grasping mechanism after grasping the shielding door module unit, so as to facilitate the subsequent transportation of the shielding door module unit in the Y-axis direction and the Z-axis direction.

[0022] In one embodiment, the gripping mechanism further comprises a protective plate, and the protective plate corresponds to the positioning member one by one, wherein the protective plate is arranged at the position where the positioning member is located and connected to the support plate;

[0023] When the positioning member is engaged and locked with the positioning hole on the shielding door module unit, the support plate can be pressed against the shielding door module unit through the protective plate.

[0024] It is understandable that the protective plate is used to separate the support plate from the shielding door module unit, so as to prevent the shielding door module unit from being damaged when the grabbing mechanism grabs the shielding door module unit.

[0025] In one embodiment, the X-axis driving mechanism includes an X-axis driving member, a driving gear and an X-axis rack, wherein the driving gear is mounted on the X-axis driving member and meshes with the X-axis rack, and the X-axis rack can move in the X-axis direction under the drive of the X-axis driving member;

[0026] Wherein, the X-axis rack is transmission connected to the grasping mechanism.

[0027] It can be understood that the meshing cooperation between the X-axis rack and the driving gear is used to realize the driving of the grabbing mechanism to move on the X-axis when the X-axis driving mechanism is working, so that the structure of the X-axis driving mechanism can be simplified.

[0028] It can be understood that using a support sleeve to support the X-axis rack can increase the contact area of ​​the X-axis bracket when supporting the X-axis rack, which has the effect of improving the stability of the X-axis bracket supporting the X-axis rack.

[0029] In one embodiment, the X-axis rack includes an X-axis rack body and teeth arranged on the X-axis rack body, the X-axis rack body can be plugged into the support sleeve, and the teeth are used to mesh with the driving gear;

[0030] Wherein, a limiting structure is also provided on the X-axis rack body, and the limiting structure can cooperate with the supporting sleeve to limit the X-axis rack body circumferentially to the supporting sleeve.

[0031] It can be understood that the cooperation between the upper limit structure of the X-axis rack body and the support sleeve is used to achieve anti-rotation limitation when the X-axis rack body moves along the X-axis direction on the support sleeve. In this way, the stability of the X-axis rack moving on the support sleeve can be improved.

[0032] In one of the embodiments, the transfer machine further includes an X-axis bracket, a support sleeve is formed on the X-axis bracket, and the X-axis rack at least partially extends into the support sleeve and is slidably connected to the support sleeve.

[0033] In one embodiment, the Z-axis driving mechanism includes a Z-axis driving member, a main elevator, an auxiliary elevator and a transmission shaft. The Z-axis driving member is connected to the main elevator in a transmission manner. The main elevator and the auxiliary elevator are connected to each other in a transmission manner through the transmission shaft. The main elevator and the auxiliary elevator can work synchronously under the drive of the Z-axis driving member to lift the shielding door module unit grasped by the grasping mechanism.

[0034] It can be understood that the main elevator and the auxiliary elevator are used together to lift the platform shielding door module unit grasped by the grasping mechanism, so that the stability of lifting the platform shielding door module unit can be improved.

[0035] In one embodiment, the Z-axis driving mechanism further includes a guide assembly, and the guide assembly is arranged outside the Z-axis driving member, the main elevator and the auxiliary elevator;

[0036] The guide assemblies each include a guide rod and a guide sleeve, wherein the guide rod is slidably connected to the guide sleeve, wherein the guide rod is fixedly connected to the Y-axis base, and the guide sleeve is fixedly connected to the support base of the transfer machine.

[0037] It is understandable that the guide assembly is used to guide the lifting of the shield door module unit, so that the consistency of the direction during the lifting of the shield door module unit can be ensured. Among them, the direction close to the center line of the transplanter is the inner side, and the direction away from the center line is the outer side.

[0038] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0039] The handling device for which protection is sought in the present application uses the storage area of ​​a rail car to carry the shielding door module unit, and then utilizes the movement of the rail car in the X-axis direction. The two sets of transfer machines cooperate with each other and drive the shielding door module unit to move in the Y-axis and Z-axis directions to achieve the position adjustment of the shielding door module unit during on-site installation. This can meet the on-site use requirements for installing the shielding door module unit, so that the handling device can achieve on-site installation of the assembled shielding door module unit, which can facilitate the on-site installation of the shielding door module unit, shortening the construction period and reducing costs; at the same time, the movement of the shielding door module unit in the X-axis direction is driven by the rail car, which can facilitate the movement of the shielding door module unit in the X-axis direction, simplifying the structure of the handling device.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] like Figure 1 , Figure 2As shown, a handling device 100 provided in an embodiment of the present application includes a rail car 10 and two sets of transfer machines 20. A storage area 11 for placing a shielding door module unit 210 is formed on the rail car 10. The two sets of transfer machines 20 are arranged on both sides of the storage area 11 and are respectively connected to the rail car 10, and the rail car 10 can drive the two sets of transfer machines 20 and the shielding door module unit 210 placed in the storage area 11 to move in the X-axis direction; wherein, the transfer machine 20 includes a grasping mechanism 21, an X-axis driving mechanism 22, a Y-axis driving mechanism and a Z-axis driving mechanism 24, the X-axis driving mechanism 22 can drive the grasping mechanism 21 to move along the X-axis direction, so as to drive the grasping mechanism 21 to grasp the shielding door module unit 210 in the storage area 11; the Y-axis driving mechanism can drive the X-axis driving mechanism 22 and the grasping mechanism 21 to move along the Y-axis direction; the Z-axis driving mechanism 24 can drive the Y-axis driving mechanism, the X-axis driving mechanism 22 and the grasping mechanism 21 to move along the Z-axis direction. That is to say, when the handling device 100 of the present application is working, the rail car 10 can be moved in the X-axis direction, and the two sets of transfer machines 20 can be moved in the Y-axis direction and the Z-axis direction to achieve the position adjustment of the platform shielding door module unit 210 during the handling. It should be noted that when the handling device 100 is used on site, the rail car 10 can be first slidably arranged on the slide rail in the X-axis direction, and then the storage frame 200 containing the platform shielding door module unit 210 can be lifted to the storage area 11 of the rail car 10 by using a crane.

[0051] It can be understood that the storage area 11 of the rail car 10 is used to carry the shielding door module unit 210, and then the rail car 10 is moved in the X-axis direction. The two sets of transfer machines 20 cooperate with each other and drive the shielding door module unit 210 to move in the Y-axis and Z-axis directions to achieve the position adjustment of the shielding door module unit 210 during on-site installation. This can meet the on-site use requirements for installing the shielding door module unit 210, so that the handling device 100 can achieve on-site installation of the assembled shielding door module unit 210, which can facilitate the on-site installation of the shielding door module unit 210 and shorten the construction period and reduce the cost. At the same time, the movement of the shielding door module unit 210 in the X-axis direction is driven by the rail car 10, which can facilitate the movement of the shielding door module unit 210 in the X-axis direction and simplify the structure of the handling device 100.

[0052] In the present application, two sets of transfer machines 20 are configured with the same structure, symmetrically arranged on both sides of the storage area 11, and move synchronously to grab the screen door module unit 210 and then move along the Y-axis direction for transportation. Among them, the rail car 10 is provided with a guide rail that cooperates with the track of the track area, and the X-axis direction is parallel to the track direction of the track area.

[0053] like Figure 3 , Figure 5As shown, the transfer machine 20 includes a grabbing mechanism 21, an X-axis driving mechanism 22, a Y-axis driving mechanism and a Z-axis driving mechanism 24. In one embodiment, the grabbing mechanism 21 includes a support plate 211 and a positioning member 212, and the positioning member 212 is fixedly connected to the support plate 211; wherein, a positioning hole 220 matching the positioning member 212 is opened on the shielding door module unit 210. In one embodiment of the present application, the positioning hole 220 is a positioning hole 220, and the positioning member 212 can be locked with the positioning hole 220 under the drive of the support plate 211 to grab the shielding door module unit 210. Here, the positioning member 212 is set as a latch, a positioning pin, etc., and at least two positioning members 212 are arranged at intervals along the Z-axis direction on each support plate 211, so that the grabbing mechanism 21 can use the locking between the two positioning members 212 and the corresponding positioning holes 220 on the shielding door module unit 210 to achieve the grabbing of the shielding door module unit 210. In one embodiment of the present application, the two positioning members 212 cooperate with the corresponding positioning holes 220 on the shielding door module unit 210 to prevent the shielding door module unit 210 from rotating and falling after being grasped, further ensuring the reliability of the grasping action. Preferably, the two positioning members 212 are symmetrically arranged at both ends of the support plate 211. It should be noted that the positioning hole 220 on the shielding door module unit 210 includes a large hole 2201 and a small hole 2202. After the positioning member 212 on the grasping mechanism 21 is inserted into the large hole 2201 of the positioning hole 220 on the shielding door module unit 210 in the X-axis direction, the grasping mechanism 21 is driven to move in the Z-axis direction by the Z-axis driving mechanism 24, so that the positioning member 212 and the small hole 2202 on the positioning hole 220 can be locked. In other embodiments, the grasping mechanism 21 can also be driven to move in the X / Y-axis direction by the X-axis driving mechanism or the Y-axis driving mechanism to realize the locking between the positioning member and the small hole on the positioning hole 220. The large hole 2201 and the small hole 2202 may be directly connected, such as being directly connected up and down in an 8-shaped pattern, or may be connected through a transition channel; for example, they may be connected through a vertical channel, or may be connected through a bending channel, etc. In addition, the large hole 2201 and the small hole 2202 may be designed as a complete circular structure or a partial arc segment structure.

[0054] It can be understood that the grasping mechanism 21 grasps the shielding door module unit 210 by means of the snap-fit ​​locking between the positioning piece 212 and the corresponding positioning hole 220 of the shielding door module unit 210. This not only simplifies the structure of the grasping mechanism 21, and facilitates the grasping mechanism 21 to grasp the shielding door module unit 210 and to withdraw the grasping mechanism 21 from the shielding door module unit 210 after installation, but also improves the stability of the grasping mechanism 21 after grasping the shielding door module unit 210, so as to facilitate the subsequent transportation of the shielding door module unit 210 in the Y-axis direction and the Z-axis direction.

[0055] like Figure 3 As shown, in this embodiment, the gripping mechanism 21 further includes a protective plate 213, and the protective plate 213 is arranged corresponding to the positioning member 212, wherein the protective plate 213 is arranged at the position where the corresponding positioning member 212 is located and connected to the support plate 211; and when the positioning member 212 grabs the positioning hole 220 on the shielding door module unit 210 and locks it, the support plate 211 can be pressed against the shielding door module unit 210 through the protective plate 213. In other words, the protective plate 213 can separate the shielding door module unit 210 grabbed by the gripping mechanism 21 from the support plate 211, so that the shielding door module unit 210 can be prevented from being damaged when the gripping mechanism 21 grabs the shielding door module unit 210. Here, the protective plate 213 can be specifically set as a rubber plate, a silicone plate, etc., which will not be elaborated here.

[0056] like Figure 2 As shown, in one embodiment, the Y-axis driving mechanism includes a first Y-axis driving mechanism 231 and a second Y-axis driving mechanism 232. When the transfer machine 20 of this embodiment is working, the first Y-axis driving mechanism 231 and the second Y-axis driving mechanism 232 can respectively drive the shielding door module unit 210 grasped by the grasping mechanism 21 to move in the Y-axis direction, and the two sections of the travel on the Y-axis are respectively controlled by the two driving mechanisms, so that the moving travel of the shielding door module unit 210 when moving in the Y-axis can be increased, so that the shielding door module unit 210 can be separated from the storage area 11 in the Y-axis direction; at the same time, the safety of the moving process is further ensured. Here, the storage area 11 for accommodating the shielding door module unit 210 is detachably connected to the protection beam 201 in the Y-axis direction and the guardrail is detachably connected to the X-axis direction. The guardrail is connected to the protection beam 201 to form a storage frame 200 for accommodating the shielding door module unit 210. When the shielding door module unit 210 needs to be separated from the storage frame 200 in the Y-axis direction, the protection beam 201 can be removed first. It should be noted that the storage frame 200 can accommodate a plurality of shielding door module units 210 arranged in sequence and at intervals in the Y-axis direction.

[0057] like Figure 2 As shown, in this embodiment, the transfer machine 20 further includes a Y-axis base 25, a telescopic beam 26 and an X-axis bracket 27, the telescopic beam 26 is slidably connected to the Y-axis base 25 and the X-axis bracket 27 in the Y-axis direction, the first Y-axis driving mechanism 231 is used to drive the telescopic beam 26 to move along the Y-axis direction on the Y-axis base 25, and the second Y-axis driving mechanism 232 is used to drive the X-axis bracket 27 to move along the Y-axis direction on the telescopic beam 26. Here, the X-axis driving mechanism 22 is installed on the X-axis bracket 27, and the Z-axis driving mechanism 24 is used to drive the Y-axis base 25 to move along the Z-axis direction.

[0058] like Figure 3As shown, in one embodiment, the X-axis driving mechanism 22 includes an X-axis driving member 221, a driving gear (not shown) and an X-axis rack 222, the driving gear is mounted on the X-axis driving member 221 and meshes with the X-axis rack 222, and the X-axis rack 222 can move in the X-axis direction under the drive of the X-axis driving member 221; wherein the X-axis rack 222 is connected to the gripping mechanism 21 in a transmission manner. Here, the X-axis driving member 221 is configured as a motor, and the X-axis rack 222 can be provided with a tooth surface on a circular shaft for meshing with the driving gear, and the X-axis rack 222 is plugged and matched with the support plate 211, and then locked with screws. When the X-axis driving mechanism 22 is working, the X-axis driving member 221 can drive the X-axis rack 222 to move in the X-axis direction through the driving gear, so that the structure of the X-axis driving mechanism 22 can be simplified.

[0059] like Figure 3 As shown, in this embodiment, a support sleeve 271 is formed on the X-axis bracket 27, and the X-axis rack 222 at least partially extends into the support sleeve 271 and is slidably connected to the support sleeve 271. Here, the X-axis rack 222 is arranged to penetrate the support sleeve 271, so that the X-axis bracket 27 can support the X-axis rack 222 with the support sleeve 271, which can increase the contact area when the X-axis bracket 27 supports the X-axis rack 222, and has the effect of improving the stability of the X-axis bracket 27 supporting the X-axis rack 222.

[0060] like Figure 3 As shown, in this embodiment, the X-axis rack 222 includes an X-axis rack body 2221 and teeth 2222 provided on the X-axis rack body 2221, the X-axis rack body 2221 can be plugged and matched with the support sleeve 271, and the teeth 2222 are used to mesh with the driving gear; wherein, a limiting structure is also provided on the X-axis rack body 2221, and the limiting structure can cooperate with the support sleeve 271 to limit the X-axis rack body 2221 circumferentially to the support sleeve 271. Here, the limiting structure is provided as a slide groove 2223 provided on the X-axis rack body 2221, and the slide groove 2223 can be plugged and matched with the support sleeve 271.
