Description

Technical Field

[0001] The present invention relates to the technical field of elevator installation, in particular to an elevator corridor hoisting tool. Background Art

[0002] With the development of society, the demand for adding elevators to existing buildings is increasing. In such cases, because buildings lack dedicated elevator shafts, an outdoor shaft must be constructed to accommodate the installation and operation of the elevator. Sufficient clearance must also be maintained between the shaft and the building to ensure adequate lighting for residents on each floor.

[0003] In the existing technology, the construction of outdoor shafts generally adopts steel structure shafts, and the shafts are connected to the building body through steel structural parts. The corridor is completed on the ground in the form of prefabricated parts to reduce the weight of the prefabricated corridor. The heavier main frame is built on site. After the main frame part is connected, the prefabricated elevator corridor is erected on the main frame, and then the corridor and the frame are fixed by welding or screwing. The gaps between the corridor, the shaft and the building body are filled and connected with other prefabricated materials. In this process, the corridor hoisting equipment is needed.

[0004] Existing hoisting equipment typically connects a fixed frame to a prefabricated corridor via screws, or uses ropes to tie the corridor's exterior and then hoist it. While both methods can complete construction, the former requires damaging the corridor's original structure during use, requiring later repairs, increasing construction time. The latter concentrates the lifting force applied to the corridor near the ropes, making it prone to damage due to uneven force when the corridor needs to be hoisted to a higher position. Furthermore, after lowering the corridor, it is difficult to extract the ropes from under the corridor. In light of this, the present invention proposes an elevator corridor hoist tool.

[0078] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0079] See also Figure 1 , this application provides the following technical solutions:

[0080] An elevator corridor hoist tooling includes a hoisting frame 1. A hoisting structure 111 is provided on the upper side of the hoisting frame 1 corresponding to the hoisting frame. The hoisting structure 111 can optionally use a lifting ring. Two movable seats 2 are symmetrically provided on the hoisting frame 1. The movable seats 2 can move horizontally on the hoisting frame 1. The movement form is that the two movable seats 2 move toward or away from each other synchronously. Two clamping frames 3 are provided corresponding to each movable seat 2. The clamping frames 3 and the movable seats 2 are horizontally slidably connected. The sliding direction of the clamping frames 3 is perpendicular to the movement direction of the movable seats 2. The two clamping frames 3 on the same movable seat 2 are symmetrically provided and can move toward or away from each other synchronously. Figure 1The directions shown in the figure are for illustration, the length direction of the lifting frame 1 is longitudinal, the width direction is transverse, the moving seat 2 moves in the longitudinal direction, and the clamping frame 3 moves in the transverse direction. In addition, a turnover mechanism 4 is arranged on the lower side of the clamping frame 3, the turnover mechanism 4 comprises a plurality of turnover frames 41, the turnover frames 41 are rotationally connected with the clamping frame 3; two turnover frames 41 are rotationally connected on the lower side of the clamping frame 3, and the turnover frames 41 belonging to the same clamping frame 3 form a corresponding corner clamping and lifting structure of the corridor. The turnover mechanism 4 is linked with the clamping frame 3, when the clamping frame 3 moves upward, the turnover frames 41 rotate towards the lower side of the clamping frame 3; when the clamping frame 3 moves downward, the turnover frames 41 rotate towards the outer side of the clamping frame 3.

[0081] Through the structure of the scheme, by means of the moving seat 2 moving in the longitudinal direction and the clamping frame 3 moving in the transverse direction, the elevator corridor below the lifting frame 1 can be gathered and clamped, the corridor is clamped from the corner position, and the turnover frames 41 are turned over during the lifting process on the lifting frame 1, so that the corridor is lifted from the lower side, thereby improving the safety and stability of the lifting.

[0082] On the basis of the above-mentioned embodiment, referring to Figure 2 , the lifting frame 1 comprises a main frame body 11, a lifting structure 111 connected with a lifting device is arranged on the upper side of the middle part of the main frame body 11; the main frame body 11 is provided with a first guide assembly 12 and a second guide assembly 13. The first guide assembly 12 is linked with the moving seat 2, and the moving seat 2 can slide horizontally along the direction of the first guide assembly 12, and the guide direction of the first guide assembly 12 is longitudinal.

[0083] The first guide assembly 12 comprises a main guide rod 121 and a secondary guide rod 122. The main guide rod 121 is rotationally connected with the main frame body 11, and external threads are arranged on both ends of the rod body, respectively. The main guide rod 121 is threadedly connected with the moving seat 2 on both sides through the thread structures on both ends. A secondary guide rod 122 is arranged on each side of the main guide rod 121, and the moving seat 2 is slidingly connected with the secondary guide rod 122. Through the combined use of the main guide rod 121 and the secondary guide rod 122, the main guide rod 121 is rotated to drive the moving seat 2 to translate. A driving assembly 14 is arranged corresponding to the main guide rod 121, the driving assembly 14 comprises a motor fixedly arranged in the main frame body 11, and the motor is linked with the main guide rod 121 through a speed reduction gear combination, and the motor drives the main guide rod 121 to rotate.

[0084] The second guide assembly 13 is linked with the clamping frame 3, and the clamping frame 3 can slide horizontally along the guide direction of the second guide assembly 13; the second guide assembly 13 does not have active power itself, and the main function is to limit the movement path of the clamping frame 3, and the guide direction of the second guide assembly 13 is transverse.

[0085] The guiding directions of the first guide assembly 12 and the second guide assembly 13 are perpendicular. When the two movable seats 2 approach each other, the four clamping frames 3 corresponding to the two movable seats 2 converge toward the middle portion below the main frame 11. When the two movable seats 2 move away from each other, the four clamping frames 3 move away from each other and disperse. Through the combination of the first guide assembly 12 and the second guide assembly 3 of this structure, the four clamping frames 3 move synchronously when converging or dispersing, thereby achieving stable clamping of the corridor and preventing the occurrence of partial gaps.

[0086] Based on the above implementation plan, see Figures 2 to 4 The movable seat 2 includes a main seat body 21, which is "L"-shaped and has a threaded hole on its vertical part, which is threadedly connected to the main guide rod 121 through the threaded hole; a horizontal plate 211 is fixedly provided on the side of the lower part of the main seat body 21 facing the main frame body 11; the horizontal plate 211 can clamp the upper part of the corridor, and its function is to further enhance the stability of the corridor clamping during the lifting process.

[0087] A first through-slot 22 and a second through-slot 23 are formed in the vertical portion of the main base body 21. The first through-slot 22 extends vertically through the main base body 21, and the clamping frame 3 is slidably connected to the main base body 21 via the first through-slot 22. The first through-slot 22 is a rectangular slot, and the clamping frame 3 can slide vertically and horizontally within the first through-slot 22, with the horizontal sliding direction being the transverse direction. The second through-slot 23 extends horizontally through the main base body 21, and the main base body 21 is slidably connected to the secondary guide rod 122 along the longitudinal direction via the second through-slot 23.

[0088] The main function of the movable base 2 is to drive the clamping frames 3 during the lifting process. By moving the two movable bases 2, the four clamping frames 3 are driven. With this structure, the parts that need to be driven during the lifting process are simplified, thereby improving the overall strength of the tooling and reducing the difficulty of maintenance.

[0089] Based on the above implementation plan, see Figures 4 to 6 The clamping frame 3 includes a connecting frame 31, the lower side of which is connected to the flip mechanism 4. A first linkage frame 32 is fixedly mounted on the upper side of the connecting frame 31. The first linkage frame 32 is a "日"-shaped structure, with one of its vertical rods slidably connected to the main base 21 through the first through-slot 22. A first reset member 321 is provided between the vertical rod and the inner wall of the first through-slot 22. The first reset member 321 is a spring that can reset the first reset member 321.

[0090] like Figure 3As shown, the secondary guide rod 122 includes a straight rod portion and an oblique rod portion. The rod body of the straight rod portion is parallel to the main guide rod 121. The oblique rod portion is provided at each end of the straight rod portion, with one end of the oblique rod portion fixedly connected to the straight rod portion and the other end extending horizontally away from the straight rod portion. The second through-slot 23 on the main base 21 passes through the first through-slot 22. The portion of the secondary guide rod 122 located within the first through-slot 22 is linked to the first linkage frame 32 of the clamping frame 3. The side of the oblique rod portion abuts against the side of the vertical rod of the first linkage frame 32 located within the first through-slot 22. The side of the first linkage frame 32 facing the oblique rod portion is an inclined surface or an arc-shaped surface. When the main base 21 is located at the end of the secondary guide rod 122, the second linkage frame 33 is located at the end of the oblique rod portion. Under the push of the oblique rod portion, the two clamping frames 3 belonging to the same main base 21 move away from each other, and the first reset member 321 is stretched. As the main base body 21 moves, the main base body 21 moves closer along the secondary guide rod 122 . In the process of passing through the oblique rod portion, the first linkage frames 32 of the two clamping frames 3 also move closer to each other.

[0091] Based on the above implementation plan, see Figures 2 to 4 The second guide assembly 13 includes a second guide frame 131. The guide direction of the second guide frame 131 is parallel to the direction of the main guide rod 121. The second guide frame 131 is a rectangular frame with a rectangular channel defined therein. The rectangular channel runs in the transverse direction and its longitudinal side is longitudinal. A second guide block 132 is slidably connected within the rectangular channel of the second guide frame 131. The second guide block 132 has a horizontal second guide hole defined therein, with the axial direction of the second guide hole being transverse.

[0092] See also Figure 4 and Figure 5 A second linkage frame 33 is fixedly provided on the upper side of the connecting frame 31 of the clamping frame 3. The second linkage frame 33 is a "7"-shaped rod body, and the cross bar part at its upper end is inserted into the second guide hole of the second guide block 132 and is slidably connected to the second guide block 132.

[0093] The connecting frame 31 is provided with a first linkage frame 32 and a second linkage frame 33. The combination of the two frames allows the connecting frame 31 to move more smoothly as a whole and improves its load-bearing capacity.

[0094] Based on the above implementation plan, see Figure 9 The connecting frame 31 includes a vertical frame 311 and a horizontal frame 312. Both are horizontal frames and are perpendicular to each other. The vertical frame 311 extends parallel to the main guide rod 121, that is, extends in the longitudinal direction. The horizontal frame 312 is located at one end of the vertical frame 311 and is arranged in the transverse direction. The vertical frame 311 and the horizontal frame 312 each rotate a flip frame 41.

[0095] Each flip frame 41 includes a horizontally arranged rotating shaft 411, which is rotatably connected to the vertical frame 311 or the horizontal frame 312 of the connecting frame 31. A flip part 412 is fixedly connected to the shaft of the rotating shaft 411. The flip part 412 includes two vertical poles. As a further improvement, a reinforcing structure such as a reinforcing rod can also be added between the vertical poles of the flip part 412. A supporting plate 413 is fixedly connected to the bottom end of the flip part 412. The supporting plate 413 and the flip part 412 are perpendicular. When the flip part 412 is in a vertical state, the supporting plate 413 is a horizontal plate extending toward the lower middle part of the main frame 11. In order to ensure that the flip frame 41 does not cause obstruction when rotating, a groove structure corresponding to the flip part 412 is provided on the connecting frame 31 to avoid the rotation.

[0096] Through the structure of the turning frame 41, at the initial stage of lifting, the turning frame 41 rotates outward to avoid the corridor. During lifting, it rotates toward the corridor, causing the support plate 413 to rotate to the bottom of the corridor and withdraw the corridor for lifting.

[0097] On the basis of the above embodiment, the flip mechanism 4 includes a main linkage assembly 42 , which is arranged between the flip frame 41 and the connecting frame 31 , and the rotating shaft 411 of the flip frame 41 is linked to the connecting frame 31 through the main linkage assembly 42 .

[0098] The main linkage assembly 42 includes a drive rod 421, which is a vertically arranged rod body with an approximately "L"-shaped cross-section. The drive rod 421 is vertically slidably connected to the connecting frame 31, and the drive rod 421 is located between the connection between the longitudinal frame 311 and the transverse frame 312 of the connecting frame 31.

[0099] The two sides of the driving rod 421 are respectively provided with tooth groups corresponding to the rotating shaft 411 on the vertical frame 311 and the horizontal frame 312, and the rotating shaft 411 is provided with tooth grooves. When the driving rod 421 rises or falls relative to the connecting frame 31, the tooth groups on it drive the rotating shaft 411 to rotate.

[0100] Because the turning frame 41 does not need to rotate too much during operation, basically, it only needs to rotate 90 degrees. In order to limit the rotation range of the turning frame 41, a limiting structure is set between the rotating shaft 411 and the connecting frame 31 to limit the rotation angle of the rotating shaft 411. This solution provides a way to implement the limiting structure, such as Figure 6 As shown, a limiting slot 414 is provided on the rotating shaft 411 , and a corresponding limiting block 415 is provided on the connecting frame 31 . When the slot wall of the limiting slot 414 rotates to abut against the limiting block 415 , the rotating shaft 411 cannot continue to rotate.

[0101] On the basis of the above embodiment, the flip mechanism 4 further includes a secondary linkage component 43 , which drives the driving rod 421 to move relative to the connecting frame 31 .

[0102] See also Figures 7 to 9 The secondary linkage assembly 43 includes a linkage rod 431. The linkage rod 431 is a "Y"-shaped rod, one end of which is rotatably connected to the lower end of the drive rod 421, and the other end extends toward the lower middle portion of the main frame 11. The end extending toward the main frame 11 is a forked end. A second reset member 432 is provided at the rotational connection between the linkage rod 431 and the drive rod 421. The second reset member 432 can be a torsion spring or a coil spring, and its function is to reset the linkage rod 431 to a horizontal state.

[0103] Corresponding to linkage rod 431, a positioning rod 433 is provided on connecting frame 31. Positioning rod 433 is a vertically extending rod, with its upper end fixedly connected to connecting frame 31 and its lower end extending toward linkage rod 431. Positioning rod 433 comprises a straight section at its lower portion. A curved section is positioned above the middle portion of the rod, i.e., the lower portion of the straight section. The upper portion of the curved section is further fixedly connected to connecting frame 31 via another straight rod. Positioning rod 433 has a circular cross-section and is provided with a circular positioning hole 434 in linkage rod 431. When linkage rod 431 is horizontal, the lower straight section of positioning rod 433 is inserted into positioning hole 434.

[0104] In order to avoid interference between the tilting frame 41 and the corner structure of the corridor when the spreader tool moves downward, a secondary linkage assembly 43 is provided. When the linkage rod 431 touches the upper part of the corridor, the external structure of the corridor pushes the linkage rod 431 upward, and the linkage rod 431 moves upward along the positioning rod 433. At this time, the drive rod 421 moves upward synchronously, and during the upward movement, the tilting frame 41 flips outward and opens. After moving up to a certain position, the positioning hole 434 of the linkage rod 431 moves to the arc section of the positioning rod 433. The linkage rod 431 deflects and tilts at the arc section position of the positioning rod 433, thereby no longer driving the drive rod 421 to move upward relative to the connecting frame 31. This ensures that when the spreader tool and the corridor initially come into contact, the tilting frame 41 will not interfere with the corner structure of the corridor.

[0105] Based on the above implementation plan, the working process of this tooling embodiment is described below. First, connect the lifting structure of the tooling's lifting frame 1 to the hook of the sling. The sling places the tooling on the ground, supporting the four drive rods 421 at its four corners. Gravity forces the tooling as a whole to move the drive rods 421 upward relative to the connecting frame 31. The teeth of the drive rods 421 rotate the shaft 411, causing the flip frame 41 to flip outward and open.

[0106] After the staff uses the sling to lift the tool, the driving rod 421 moves downward relative to the connecting frame 31 under the action of gravity, the rotating shaft 411 rotates, and the turning frame 41 rotates downward. Then the staff can lower the tool from above the corridor to be lifted. When the four clamping frames 3 are not gathered together, the corridor can pass between the four clamping frames 3 and the turning frame 41. After the tool is placed, start the motor to rotate the main guide rod 121, move the moving seats 2 closer to each other, gather the four clamping frames 3, and move the support plate 413 of the turning frame 41 to the bottom of the corridor. The ground of the support plate 413 can be set to have a larger plate surface to ensure that it has a sufficiently large contact area with the corridor, thereby dispersing the weight of the corridor and avoiding the problem of the bottom surface of the corridor being convex during the lifting process.

[0107] In order to prevent the turning frame 41 from touching the upper part of the corridor during the descent phase, a secondary linkage assembly 43 is provided in this tool. When the tool is lowered, the linkage rod 431 will first contact the top surface of the corridor. Under the constraints of the positioning hole 434 and the positioning rod 433, the linkage rod 431 will not flip when it is in the straight rod part at the bottom of the positioning rod 433. As the top surface of the corridor pushes the bottom surface of the linkage rod 431 from bottom to top, the linkage rod 431 will drive the driving rod 421 to move upward synchronously. As the driving rod 421 moves upward, the turning frame 41 flips and tilts outward, and the support plate 413 will not affect the installation of this tool to the outside of the corridor. When the relative position of the linkage rod 431 and the positioning rod 433 moves to the arc section of the positioning rod 433, the driving rod 421 also moves to the maximum height, so the driving rod 421 can no longer drive the linkage rod 431 to continue to rise. At this time, the linkage rod 431 can be flipped upward along the sliding cooperation path of the positioning hole 434 and the arc section of the positioning rod 433. After flipping, the linkage rod 431 will be placed at the corner of the corridor in an inclined shape, so that it will no longer be affected by the corridor or affect the corridor.

[0108] After the lifting, the tooling and the corridor are placed synchronously on the frame between the elevator shaft and the building, the frame will generate a reaction force on the driving rod 421. The lower end of the driving rod 421 is lower than the bottom surface of the support plate 413, and there is enough space for the support plate 413 to tilt up. Therefore, after the corridor is placed on the frame and positioned, the staff uses the driving tooling to move the moving seats 2 away from each other, releasing the clamping effect of the clamping frame 3.

[0109] On the basis of the above implementation scheme, the bottom end of the driving rod 421 is rotatably connected to a plurality of balls 426 , and the balls 426 can make the driving rod 421 move along the ground more smoothly.

[0110] Based on the above implementation scheme, two upper and lower blocks are set on the side of the driving rod 421. The two blocks are located on both sides of the connecting frame 31. The blocks limit the movement range of the driving rod 421 and also prevent the driving rod 421 from falling off the connecting frame 31.

[0111] On the basis of the above embodiment, elastic pads, such as rubber pads, are provided on the contact surfaces of the clamping frame 3 and the turnover frame 41 with the corridor.

[0112] Based on the above implementation plan, see Figure 7 and Figure 8 The tooth assembly includes several fixed teeth 422 and one movable tooth 423. The fixed teeth 422 are arranged vertically, and the movable teeth 423 are positioned below the fixed teeth 422. A tooth groove 425 is provided on the drive rod 421, through which the movable teeth 423 are vertically slidably connected to the drive rod 421. A support member 424 is provided below the movable teeth 423. The support member 424 is a curved metal bar that fits within the tooth groove 425, with its curved portion protruding outward. With this structure, the number of tooth grooves on the rotating shaft 411 is equal to the sum of the number of fixed teeth 422 and the movable teeth 423.

[0113] When the driving rod 421 moves upward relative to the connecting frame 31, the teeth set drives the rotating shaft 411 to rotate, thereby rotating the tilting frame 41. After rotating to the movable teeth 423, the tilting frame 41 is tilted outward and opened. When the lifting frame 1 continues to pull upward and the driving rod 421 is lifted off the ground, the movable teeth 423 and the support member 424 elastically support the movable teeth 423, relying on the force of the support member 424, and the rotating shaft 411 is pressed against it, preventing it from rotating, thereby maintaining the tilting frame 41 in the outward state.

[0114] Through the setting of this structure, when the flip frame 41 is turned outward, the movable teeth 423 maintain the turned-out state of the flip frame 423, and at the same time it is supported by the elastic support member 424, so that the contact force between the rotating shaft 411 and the movable teeth 423 has a certain elastic force, and it is not easy to damage the contact point between the two.
