Description

Technical Field

[0001] The invention belongs to the technical field of subway shield door installation, in particular to a transfer hanger for subway shield door installation. Background Art

[0002] The transfer hoist for subway screen door installation is a tool for transferring modular or bulk subway screen doors from the assembly area or warehouse to the installation location of the subway platform. It has the characteristics of stable structure, flexible adjustment, safety and reliability, and easy operation.

[0003] In the prior art, during the lifting of a long rectangular subway screen door, the transfer hoist is first moved to the top of the subway screen door to be lifted, and the hooks on the steel cables on the transfer hoist are connected together by connecting ropes to the lifting buckles on the subway screen door, thereby completing the fixation of the subway screen door. Subsequently, the subway screen door is lifted up by contracting the steel cables, and the transfer hoist is moved to transport the subway screen door to the location where the subway screen door is installed.

[0004] There are still some problems in the actual use of the existing transfer hoist for installing subway screen doors. The connecting devices used to lift the subway screen doors are steel cables and connecting ropes. At the same time, because the subway screen doors are heavy, when the transfer hoist turns, the speed of the transfer hoist is reduced, and the subway screen door will be displaced under the action of inertia, and then collide with the transfer hoist, thereby damaging the appearance of the subway screen door. In addition, the transfer hoist transfers the subway screen door from the assembly area or warehouse to the installation position of the subway platform. During this process, when encountering bumpy road conditions, the clamped subway screen door will shake up and down. During the shaking process, the glass on the subway screen door touches the hook on it, resulting in damage to the glass on the subway screen door.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1

[0040] like Figures 1 to 10 As shown, a transfer sling for installing a subway screen door according to an embodiment of the present invention comprises a sling body 1, a limit rod 11 is fixedly connected to the top of the sling body 1, a steel cable 12 is slidably connected to the middle of the bottom end of the limit rod 11, a bidirectional hook 13 is fixedly connected to the output end of the steel cable 12, a steering assembly is arranged at one end of the bottom of the sling body 1, the steering assembly is used to adjust the movement direction of the transfer sling, the steering assembly comprises a steering shell 21, the steering shell 21 is fixedly connected to one end of the bottom of the sling body 1, and the steering shell 21 is fixedly connected to one end of the bottom of the sling body 1. A steering shaft 22 is rotatably connected in the inner part of the housing 21, the top of the steering shaft 22 passes through the steering housing 21, the bottom of the steering shaft 22 is fixedly connected to a limit block 1 23, a rotating rod 24 is rotatably connected between the bottoms of the limit blocks 1 23, a roller 25 is symmetrically fixedly connected to the surface of the rotating rod 24, the top of the steering shaft 22 is symmetrically fixedly connected to a limit block 26, a fixing rod 27 is fixedly connected between the two limit blocks 26, a pull rod 28 is rotatably connected to the surface of the fixing rod 27, and a fixing plate 31 is fixedly connected to one side of the sling body 1 near the middle;

[0041] The bottom of the fixing plate 31 is symmetrically provided with a clamping assembly, which is used to prevent the subway screen door from being displaced during the transportation process;

[0042] A packaging component is arranged between the fixing plates 31, and the packaging component is used to prevent the subway screen door from colliding with large particles during the transportation process.

[0043] Specifically, there are still some problems in the actual use of the existing transfer hoist for installing the subway screen door. The connecting devices used to lift the subway screen door are the steel cable 12 and the connecting rope 513. At the same time, because the subway screen door is heavy, when the hoist body 1 turns, the speed of the hoist body 1 decreases, and the subway screen door will be displaced under the action of inertia, and then collide with the hoist body 1, thereby damaging the appearance of the subway screen door. In addition, the hoist body 1 transfers the subway screen door from the assembly area or warehouse to the installation position of the subway platform. During this process, when encountering bumpy road conditions, the clamped subway screen door will shake up and down. During the shaking process, the glass on the subway screen door touches the two-way hook 13 on it, resulting in the problem of damage to the glass on the subway screen door.

[0044] Therefore, the present invention solves this problem by setting a corresponding structure. In the initial state, four steering assemblies are provided, and the limit rods 11 are symmetrically arranged. By pulling the pull rods 28 on the same side at the same time, the hoist body 1 is driven to move above the subway screen door to be lifted. In the initial state, the subway screen door is placed on the placement rack, and the four sides of the subway screen door are not in contact with the placement rack. At this time, the subway screen door is clamped by the clamping assembly, and then the pull rod 28 on the other side is pulled to make the hoist body 1 move in the opposite direction until the subway screen door is no longer on the placement rack. At this time, the clamping assembly and the subway screen door are packaged by the packaging assembly, so that the packaging assembly is subsequently hoisted by the two-way hook 13 on the steel cable 12, and the clamping assembly and the packaging assembly are displaced on the fixed plate 31 by contracting the steel cable 12. Finally, by rotating and pulling the pull rod 28, the hoist body 1 is turned and displaced until the subway screen door is shipped to the location where the subway screen door is installed.

[0045] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in this embodiment, the fixing plate 31 is symmetrically provided with a displacement groove 1 32 , and the fixing plate 31 is provided with a displacement groove 2 33 , and the displacement groove 1 32 is connected to the displacement groove 2 33 .

[0046] Specifically, the depth of displacement groove 1 32 is deeper than that of displacement groove 2 33, and displacement groove 1 32 is connected to displacement groove 2 33, so that displacement block 1 41 sliding in displacement groove 1 32 partially slides in displacement groove 2 33, thereby not affecting the displacement of displacement block 1 41, and also making displacement block 1 41 only perform vertical linear motion under the limiting action of displacement groove 1 32. In addition, packaging base plate 51 and packaging cover plate 53 sliding in displacement groove 2 33 also move under the limiting action of displacement groove 2 33, ensuring that packaging base plate 51 and packaging cover plate 53 will not undergo horizontal linear displacement after being lifted.

[0047] Embodiment 2

[0048] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0049] like Figure 2 and Figures 5 to 8 As shown, the clamping assembly of this embodiment includes a displacement block 41, which is slidably connected in a displacement groove 32, and a clamping plate 42 is fixedly connected to the bottom of one end of the displacement block 41 away from the fixed plate 31, and a motion groove 3 43 is provided at one end of the displacement block 41 close to the clamping plate 42, and a threaded rod 44 is rotatably connected in the motion groove 3 43, and a threaded ring 45 is threadedly connected to one end of the threaded rod 44 away from the clamping plate 42, and a clamping plate 2 46 is fixedly connected to one end of the threaded ring 45 close to the clamping plate 42.

[0050] Specifically, in the initial state, the threaded collar 45 is located at the top of the clamping plate 42, the clamping plate 42 is located at the bottom of the displacement groove 32 and only performs vertical linear motion under the limiting effect of the displacement groove 32, the bottom end of the subway screen door on the placement frame and the top of the clamping plate 42 are in the same horizontal plane, the subway screen door is located between the adjacent surfaces of the clamping plate 42 and the clamping plate 2 46, and the adjacent surfaces of the clamping plate 42 and the clamping plate 2 46 are both provided with silicone soft pads, when the middle part of the sling body 1 is located directly above the subway screen door, the corners of the four sides of the subway screen door are located within the top surface of the clamping plate 42;

[0051] In the process of clamping the subway screen door, the micro motor on the threaded rod 44 is started, and the threaded rod 44 is driven to rotate by the output shaft of the micro motor, thereby driving the threaded collar 45 to move downward on the threaded rod 44, and driving the clamping plate 2 46 to move together with it under the limiting action of the motion groove 3 43, and then the clamping plate 2 46 and the clamping plate 1 42 clamp the corners of the subway screen door located therebetween, and then the subway screen door is clamped and fixed under the joint action of the remaining clamping devices, because silicone cushions are arranged on the adjacent surfaces of the clamping plate 1 42 and the clamping plate 2 46, the appearance of the subway screen door is prevented from being damaged when it is clamped and fixed by the clamping plate 1 42 and the clamping plate 2 46.

[0052] The present invention gradually displaces the clamping plate 2 46 toward the direction approaching the clamping plate 1 42, so that the corners of the subway screen door located between the clamping plate 1 42 and the clamping plate 2 46 are clamped, and finally the four corners of the long rectangular subway screen door are clamped and fixed by the clamping plate 1 42 and the clamping plate 2 46. At the same time, the displacement block 1 41 slides in the displacement groove 1 32, thereby preventing the subway screen door from being displaced under the action of inertia when the existing transfer hoist turns, and then colliding with the hoist body 1, thereby causing damage to the appearance of the subway screen door, thereby ensuring the appearance consistency of the subway screen door during the transfer process.

[0053] like Figure 5 and Figure 6 As shown, the shape of the clamping plate 1 42 in this embodiment matches the shape of the clamping plate 2 46, and the clamping plate 1 42 contacts the bottom end of the corner of the subway screen door.

[0054] Specifically, the shapes of the clamping plate 1 42 and the clamping plate 2 46 match each other, so that when the clamping plate 1 42 is clamped, the clamped part of the subway screen door is evenly stressed, thereby preventing damage to the clamped part of the subway screen door due to different force areas; the clamping plate 1 42 contacts the bottom end of the corner of the subway screen door, so that the corner of the subway screen door can be clamped and fixed by the clamping plate 1 42 and the clamping plate 2 46.

[0055] like Figure 2 and Figure 7 As shown, the packaging assembly described in this embodiment includes a packaging base plate 51, and the packaging base plate 51 is slidably connected in the displacement groove 33. The limiting grooves 52 are symmetrically arranged on the packaging base plate 51. A packaging cover plate 53 is slidably connected between the displacement grooves 32. The top of the packaging cover plate 53 is symmetrically fixedly connected with the limiting lock buckles 54, and a connecting rope 513 is fixedly connected between the two limiting lock buckles 54 and the two-way hook 13.

[0056] Specifically, in the initial state, two groups of limit lock buckles 54 are provided, and the two groups of limit lock buckles 54 are respectively fixedly connected to the two bidirectional hooks 13 through the connecting rope 513, and the packaging cover plate 53 only performs vertical linear motion in the second displacement groove 33 under the action of the second displacement groove 33 and the bidirectional hook 13;

[0057] When the subway screen door is clamped and the hanger body 1 is reset, the packaging bottom plate 51 is pushed to slide to the other end of the bottom of the displacement groove 33. At this time, the packaging bottom plate 51 is located directly below the packaging cover plate 53 and the top of the packaging bottom plate 51 is in conflict with the top of the displacement block 41, thereby supporting the clamped subway screen door.

[0058] like Figure 2 , Figure 7 and Figure 8As shown, the packaging bottom plate 51 described in this embodiment is located on the movement track of the packaging cover plate 53.

[0059] Specifically, the packaging bottom plate 51 is located on the movement track of the packaging cover plate 53, so that the packaging bottom plate 51 is in conflict with the packaging cover plate 53, thereby packaging the clamped subway screen door.

[0060] like Figure 2 and Figures 7 to 10 As shown, the packaging component described in this embodiment also includes a motion groove 55, which is symmetrically arranged on both sides of the interior of the packaging cover plate 53. The motion groove 55 is rotatably connected to a limit rod 2 56, and seven limit rods 2 56 are provided. The bottom ends of the seven limit rods 2 56 are fixedly connected to a limit block 3 57. A limit rod 2 56 near one end of the displacement groove 1 32 is fixedly connected to a rotating block 59 at the top, and a positioning plate 510 is arranged at the top of the rotating block 59. A transmission belt 1 511 is transmission-connected between the limit rods 2 56 in one side of the motion groove 1 55, and a motion groove 2 58 is arranged between the two motion grooves 1 55. The motion groove 2 58 is connected to the motion groove 1 55, and a transmission belt 2 512 is transmission-connected between the two limit rods 2 56 in the motion groove 2 58.

[0061] Specifically, in the initial state, the shape of the third limit block 57 matches the shape of the limit groove 52. When the package cover plate 53 contacts the package bottom plate 51, the portion of the package bottom plate 51 sliding in the displacement groove 2 33 is located below the displacement block 1 41, and the third limit block 57 completely passes through the limit groove 52. The direction of the positioning plate 510 is the same as that of the third limit block 57.

[0062] When the packaging bottom plate 51 is located directly below the packaging cover plate 53, the packaging cover plate 53 is displaced downward along the second displacement groove 33 until the packaging cover plate 53 contacts the packaging bottom plate 51. At this time, the second limit rod 56 and the third limit block 57 on the packaging cover plate 53 pass through the limit groove 52. At this time, the rotating block 59 is rotated 90 degrees, so that the second limit rod 56 and the third limit block 57 rotate together with the rotating block 59. By observing the direction of the positioning plate 510, the rotation direction of the third limit block 57 is determined. When the limit rod 2 56 rotates, the transmission belt 1 511 and the transmission belt 2 512 drive the remaining limit rods 2 56 to rotate, thereby causing all the limit blocks 3 57 to rotate, so that the limit blocks 3 57 now come into contact with the bottom surface of the packaging bottom plate 51, and the packaging cover plate 53 is displaced upward, and then through the contact between multiple limit blocks 3 57 and the packaging bottom plate 51, the packaging bottom plate 51 and the clamping device thereon and the subway screen door are driven to move along with the packaging cover plate 53.

[0063] When the packaging cover plate 53 of the present invention conflicts with the packaging base plate 51, the limiting rod 2 56 and the limiting block 3 57 thereon pass through the limiting groove 52. At this time, by rotating the positioning plate 510, under the action of the transmission belt 1 511 and the transmission belt 2 512, all the limiting rods 2 56 are driven to rotate, and then all the limiting blocks 3 57 are turned, so that the packaging base plate 51 and the packaging cover plate 53 are clamped under the action of the limiting blocks 3 57, so that the subway screen door is covered by the packaging base plate 51 and the packaging cover plate 53, and then it is protected to prevent the subway screen door from shaking up and down when encountering bumpy road conditions during the lifting process. During the shaking process, the glass on the subway screen door touches the two-way hook 13 on it, resulting in the problem of damage to the glass on the subway screen door. At the same time, the packaging base plate 51 and the packaging cover plate 53 slide in the displacement groove 2 33, further preventing the subway screen door from colliding with the hoist body 1 during the lifting process.

[0064] like Fig.10 As shown, the second movement slot 58 in this embodiment is arranged between the second limiting rod 56 to which the rotating block 59 is fixed and the second limiting rod 56 symmetrical thereto.

[0065] Specifically, the setting of the second motion groove 58 allows the rotating blocks 59 on both sides to drive the second limiting rod 56 below them to move, and can also transmit through the transmission belt 512 between the second limiting rods 56 on both sides in the second motion groove 58, so that the second limiting rod 56 on the other side also rotates synchronously.

[0066] like Figure 2 , Figure 7 and Figure 8 As shown, the limiting groove 52 of this embodiment corresponds to the limiting block 3 57 one by one, the length of the limiting rod 2 56 leaking out from the bottom of the packaging cover plate 53 is the same as the depth of the limiting groove 52, and the shape of the packaging bottom plate 51 matches the packaging cover plate 53.

[0067] Specifically, when the packaging bottom plate 51 conflicts with the packaging cover plate 53 , the length of the second limiting rod 56 leaking out from the bottom of the packaging cover plate 53 is the same as the depth of the limiting groove 52 , so that the third limiting block 57 completely passes through the corresponding limiting groove 52 .

[0068] like Figure 2 , Figure 7 and Figure 8 As shown, the internal space formed when the packaging cover plate 53 of this embodiment abuts against the packaging bottom plate 51 covers the clamping assembly.

[0069] Specifically, the internal space formed when the packaging cover plate 53 and the packaging bottom plate 51 collide with each other covers the clamping assembly, thereby preventing the subway screen door on the clamping assembly from colliding with the two-way hook 13 during the up and down shaking of the road due to the bumps in the road surface, thereby preventing the glass on the subway screen door from cracking.

[0070] The present invention ensures the appearance consistency of the subway shielding door during the hoisting process by clamping the subway shielding door with the clamping plate 1 42 and the clamping plate 2 46 and encapsulating the subway shielding door with the encapsulation bottom plate 51 and the encapsulation cover plate 53.

[0071] Working principle:

[0072] By pulling the pull rod 28 on the same side at the same time, the hoist body 1 is driven to move above the subway screen door to be hoisted. In the initial state, the subway screen door is placed on the placement frame, and the four sides of the subway screen door are not in contact with the placement frame. At this time, the micro motor on the threaded rod 44 is started, and the threaded rod 44 is driven to rotate through the output shaft of the micro motor, and then the threaded collar 45 is driven to move downward on the threaded rod 44, and the clamping plate 2 46 is driven to move together with it under the limiting action of the motion groove 3 43, and then the clamping plate 2 46 and the clamping plate 1 42 clamp the corners of the subway screen door between them, and then the subway screen door is clamped and fixed under the joint action of the remaining clamping devices;

[0073] The subway screen door is clamped by the clamping assembly, and then the pull rod 28 on the other side is pulled to make the hanger body 1 move in the opposite direction until the subway screen door is no longer on the placement rack. At this time, the packaging bottom plate 51 is pushed to slide to the other end of the bottom of the displacement groove 2 33. At this time, the packaging bottom plate 51 is located directly below the packaging cover plate 53 and the top of the packaging bottom plate 51 is in conflict with the top of the displacement block 1 41;

[0074] Since the depth of the displacement groove 1 32 is deeper than that of the displacement groove 2 33, the displacement groove 1 32 is connected with the displacement groove 2 33, so that the displacement block 1 41 sliding in the displacement groove 1 32 partially slides in the displacement groove 2 33, thereby not affecting the displacement of the displacement block 1 41, and the displacement block 1 41 is limited by the displacement groove 1 32, and the displacement block 1 41 only performs vertical linear motion. In addition, the packaging bottom plate 51 and the packaging cover plate 53 sliding in the displacement groove 2 33 also move under the limit of the displacement groove 2 33, ensuring that the packaging bottom plate 51 and the packaging cover plate 53 will not be horizontally linearly displaced after being lifted;

[0075] At this time, the packaging cover plate 53 is displaced downward along the displacement groove 2 33 until the packaging cover plate 53 conflicts with the packaging bottom plate 51. At this time, the limiting rod 2 56 and the limiting block 3 57 on the packaging cover plate 53 pass through the limiting groove 52. At this time, the rotating block 59 is rotated 90 degrees, so that the limiting rod 2 56 and the limiting block 3 57 rotate together with the rotating block 59. By observing the direction of the positioning plate 510, the rotation direction of the limiting block 3 57 is determined. When the limiting rod 2 56 rotates, the transmission belt 1 511 and the transmission belt 2 512 are used to drive the remaining limiting rods 2 56 to rotate, so that all the limiting blocks 3 57 rotate, so that the limiting blocks 3 57 conflict with the bottom surface of the packaging bottom plate 51 at this time. At this time, the packaging cover plate 53 is displaced upward, and then through the conflict between multiple limiting blocks 3 57 and the packaging bottom plate 51, the packaging bottom plate 51 and the clamping device thereon and the subway screen door are driven to move together with the packaging cover plate 53.

[0076] Finally, by rotating and pulling the pull rod 28, the hoisting device body 1 is turned and displaced until the subway screen door is hoisted to the location where the subway screen door is installed.
