Description

Technical Field

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

[0002] With the development of society, the demand for additional elevators in existing buildings is increasing. In this case, since there is no dedicated elevator shaft designed for the building, an outdoor shaft needs to be added for the installation and operation of the elevator, and there needs to be a sufficient distance between the shaft and the building to ensure the lighting environment of the residents on each floor.

[0003] In the prior art, the construction of outdoor shafts generally uses steel structure shafts, and the shafts are connected to the building body through steel structural parts. The corridor is made 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 lifting equipment of the corridor is needed.

[0004] Existing hoisting equipment usually connects the fixed frame to the prefabricated corridor by screwing, or uses ropes to tie the corridor outside and then hoist it. Although both methods can be used to complete the construction, the former needs to destroy the original structure of the corridor during use, and then repair the damaged part later, which increases the construction time; the latter gives the corridor a lifting force concentrated near the rope. When the corridor needs to be hoisted to a higher position, it is easy to damage the external structure of the corridor due to uneven force, and after the corridor is lowered, there is still a problem that it is difficult to pull out the rope under the corridor. In view of this, the present invention proposes an elevator corridor hoist tool. Summary of the invention

[0078] The following will be combined with the 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 described embodiments 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 creative work 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 device. The hoisting structure 111 can optionally use a lifting ring. Two moving seats 2 are symmetrically provided on the hoisting frame 1. The moving seats 2 can move in the horizontal direction on the hoisting frame 1. The movement form is that the two moving seats 2 move toward or away from each other synchronously. Two clamping frames 3 are provided corresponding to each moving seat 2. The clamping frames 3 and the moving seats 2 are horizontally slidably connected. The sliding direction of the clamping frames 3 is perpendicular to the movement direction of the moving seats 2. The two clamping frames 3 on the same moving seat 2 are symmetrically provided and can move toward or away from each other synchronously. Figure 1The directions shown are for illustration purposes only. The length direction of the lifting frame 1 is longitudinal, and 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 flipping mechanism 4 is provided on the lower side of the clamping frame 3. The flipping mechanism 4 includes a plurality of flipping frames 41. The flipping frames 41 are rotatably connected to the clamping frame 3. Two flipping frames 41 are rotatably connected to the lower side of each clamping frame 3. The flipping frames 41 belonging to the same clamping frame 3 form a corner clamping and lifting structure of the corresponding corridor. The flipping mechanism 4 is linked to the clamping frame 3. When the clamping frame 3 moves up, the flipping frame 41 rotates toward the bottom of the clamping frame 3; when the clamping frame 3 moves down, the flipping frame 41 rotates toward the outside of the clamping frame 3.

[0081] Through the structure of the present invention, with the help of the movable seat 2 that moves in the longitudinal direction and the clamping frame 3 that moves in the transverse direction, the elevator corridor below the lifting frame 1 can be clamped in a concentrated manner and clamped from the corner position of the corridor. With the help of the flipping action of the flipping frame 41 during the pulling process of the lifting frame 1, it is lifted from the lower side of the corridor, thereby improving the safety and stability of the lifting.

[0082] Based on the above implementation scheme, see Figure 2 The lifting frame 1 includes a main frame 11, and a lifting structure 111 that can be connected to the lifting device is arranged on the upper side of the middle of the main frame 11; a first guide assembly 12 and a second guide assembly 13 are arranged on the main frame 11. 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 guiding direction of the first guide assembly 12 is the longitudinal direction.

[0083] The first guide assembly 12 includes a main guide rod 121 and a secondary guide rod 122. The main guide rod 121 is rotatably connected to the main frame 11, and external threads are respectively provided at both ends of the rod body. The main guide rod 121 is threadedly connected to the moving seat 2 on both sides through the threaded structures at both ends. A secondary guide rod 122 is respectively provided on both sides of the main guide rod 121, and the moving seat 2 and the secondary guide rod 122 are slidably connected. 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 provided corresponding to the main guide rod 121, and the driving assembly 14 includes a motor fixedly arranged inside the main frame 11, and the motor is linked to the main guide rod 121 through a reduction gear combination, and the main guide rod 121 is driven to rotate by the motor.

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

[0085] The guiding directions of the first guiding component 12 and the second guiding component 13 are perpendicular; when the two moving seats 2 approach each other, the four clamping brackets 3 corresponding to the two moving seats 2 gather towards the middle part below the main frame body 11; when the two moving seats 2 move away from each other, the four clamping brackets 3 move away from each other and disperse. Through the combination of the first guiding component 12 and the second guiding component 3 in this structure, the four clamping brackets 3 move synchronously when gathering or dispersing, so as to achieve stable clamping of the corridor and avoid the situation of local position being clamped empty.

[0086] Based on the above implementation, refer to Figures 2 to 4 , the moving seat 2 includes a main seat body 21, the main seat body 21 is in an "L" shape, and a threaded hole is provided on its vertical part, and is threadedly connected to the main guiding rod 121 through the threaded hole; on the side of the lower part of the main seat body 21 facing the main frame body 11, a cross plate 211 is fixedly arranged; the cross plate 211 can clamp the upper part of the corridor, and its function is to further enhance the stability of clamping the corridor during the lifting process.

[0087] A first through groove 22 and a second through groove 23 are provided on the vertical part of the main seat body 21. The first through groove 22 is a through groove vertically penetrating the main seat body 21, and the clamping bracket 3 is slidably connected to the main seat body 21 through the first through groove 22; the first through groove 22 is a rectangular slot, and the clamping bracket 3 can slide vertically and horizontally in the first through groove 22, and the horizontal sliding direction is transverse; the second through groove 23 is a through groove horizontally penetrating the main seat body 21, and the main seat body 21 is slidably connected to the auxiliary guiding rod 122 along the longitudinal direction through the second through groove 23.

[0088] The moving seat 2 mainly plays a role in driving the clamping bracket 3 during the hoisting process. By moving the two moving seats 2, the four clamping brackets 3 are driven. With this structure, the structural part that needs to be driven during the hoisting process is simplified, thereby improving the overall strength of the tooling and reducing the difficulty of maintenance and repair.

[0089] Based on the above implementation, refer to Figures 4 to 6 , the clamping bracket 3 includes a connecting bracket 31, and the lower side of the connecting bracket 31 is connected to the flipping mechanism 4. A first linkage bracket 32 is fixedly arranged on the upper side of the connecting bracket 31. The first linkage bracket 32 is in a "day" - shaped structure, and one of its vertical rods is slidably connected to the main seat body 21 through the first through groove 22; a first reset member 321 is provided between the vertical rod and the inner wall of the first through groove 22. The first reset member 321 is a spring, which can reset the first reset member 321.

[0090] As Figure 3As shown, the auxiliary guide rod 122 includes a straight rod portion and an oblique rod portion, and the rod body of the straight rod portion is parallel to the main guide rod 121; an oblique rod portion is provided at each end of the straight rod portion, one end of the oblique rod portion is fixedly connected to the straight rod portion, and the other end extends in a horizontal direction away from the straight rod portion. The second through slot 23 on the main seat body 21 passes through the first through slot 22; the part of the auxiliary guide rod 122 located in the first through slot 22 is linked with the first linkage frame 32 of the clamping frame 3. The side of the oblique rod portion and the side of the vertical rod of the first linkage frame 32 located inside the first through slot 22 are against each other, and the side of the first linkage frame 32 corresponding to the oblique rod portion is an inclined surface or an arc surface. When the main seat body 21 is located at the end of the auxiliary 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 seat body 21 are away from each other, and at this time the first reset member 321 is stretched. As the main seat body 21 moves, the main seat body 21 moves closer along the secondary guide rod 122 , and 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 scheme, 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, and a rectangular channel is provided inside the second guide frame 131. The rectangular channel runs in the horizontal direction, and the long side direction is in the longitudinal direction. A second guide block 132 is slidably connected in the rectangular channel of the second guide frame 131. The second guide block 132 is provided with a horizontal second guide hole, and the axial direction of the second guide hole is in the horizontal direction.

[0092] See also Figure 4 and Figure 5 A second linkage frame 33 is fixedly arranged 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 respectively. The combination of the two position frames enables the connecting frame 31 to move more smoothly as a whole and improves its bearing capacity.

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

[0095] Each flip frame 41 includes a horizontally arranged rotating shaft 411, and the rotating shaft 411 is rotatably connected to the longitudinal frame 311 or the transverse frame 312 of the connecting frame 31. The flip part 412 is fixedly connected to the shaft of the rotating shaft 411, and the flip part 412 includes two vertical poles. As a further improvement scheme, 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, and the supporting plate 413 is perpendicular to the flip part 412. 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 will not cause obstruction when rotating, a groove structure for avoidance is provided on the connecting frame 31 corresponding to the flip part 412.

[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, so that the support plate 413 rotates to the bottom of the corridor and the corridor is withdrawn for lifting.

[0097] On the basis of the above implementation scheme, 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 with the connecting frame 31 through the main linkage assembly 42 .

[0098] The main linkage assembly 42 includes a driving rod 421, which is a vertically arranged rod body, and the cross-section of the rod body is approximately "L"-shaped. The driving rod 421 is vertically slidably connected to the connecting frame 31, and the driving 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 longitudinal frame 311 and the transverse 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 move 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°. 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, and the rotation angle of the rotating shaft 411 is limited by the limiting structure. This solution provides a way to implement the limiting structure, such as Figure 6 As shown, a limiting groove 414 is provided on the rotating shaft 411, and a limiting block 415 is correspondingly provided on the connecting frame 31. When the groove wall of the limiting groove 414 rotates to abut against the limiting block 415, the rotating shaft 411 cannot continue to rotate.

[0101] On the basis of the above implementation scheme, the flip mechanism 4 further includes a secondary linkage component 43 , and the secondary linkage component 43 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, which is a "Y"-shaped rod body, one end of which is rotatably connected to the lower end of the driving rod 421, and the other end extends toward the lower middle of the main frame body 11, and the end extending toward the main frame body 11 is a forked end. A second reset member 432 is provided at the rotation connection between the linkage rod 431 and the driving 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 the linkage rod 431, a positioning rod 433 is provided on the connecting frame 31. The positioning rod 433 is a rod body extending in the vertical direction, the upper end of which is fixedly connected to the connecting frame 31, and the lower end extends toward the linkage rod 431; the lower part of the positioning rod 433 is a straight rod section, and the middle position of the rod body, that is, the upper side of the straight rod section at the lower part is provided with an arc section, and the upper side of the arc section is fixedly connected to the connecting frame 31 through another straight rod. The cross section of the positioning rod 433 is circular, and a positioning hole is provided on the linkage rod 431, and the positioning hole 434 is a circular hole. When the linkage rod 431 is in a horizontal state, the straight rod section at the lower part of the positioning rod 433 is inserted into the positioning hole 434.

[0104] In order to avoid interference between the flip frame 41 and the corner structure of the corridor when the sling 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 will push the linkage rod 431 to move upward, and the linkage rod 431 moves upward along the positioning rod 433. At this time, the driving rod 421 moves upward synchronously, and during the upward movement, the flip 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, and the linkage rod 431 deflects and tilts at the arc section position of the positioning rod 433, thereby no longer driving the driving rod 421 to move upward relative to the connecting frame 31. This ensures that when the sling tool and the corridor are initially in contact, the flip frame 41 will not interfere with the corner structure of the corridor.

[0105] On the basis of the above implementation scheme, the working process of the implementation scheme of the tooling is given. First, the lifting structure of the lifting frame 1 of the tooling is connected to the hook of the sling. The sling first places the tooling on the ground, and the four driving rods 421 at the four corners are supported on the ground. Under the action of gravity, the tooling as a whole causes the driving rods 421 to move upward relative to the connecting frame 31, and the tooth group of the driving rod 421 drives the rotating shaft 411 to rotate, and the flip frame 41 flips outward and opens.

[0106] After the staff uses the lifting device 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, and 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 through 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 seat 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 board 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 descending stage, a secondary linkage assembly 43 is provided in the tooling. When the tooling is lowered, the linkage rod 431 will first contact the top surface of the corridor. Under the restriction of the positioning hole 434 and the positioning rod 433, the linkage rod 431 will not turn over 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 up synchronously. As the driving rod 421 moves up, the turning frame 41 turns and tilts outward, and the support plate 413 will not affect the tooling to be set 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 the flipping, the linkage rod 431 will be placed at the corner of the corridor in an inclined state, so that it will no longer be affected by the corridor or affect the corridor.

[0108] After the lifting, when the tooling and the corridor are synchronously placed 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 top of the frame and positioned, the staff uses the driving tooling to move the moving seats 2 away from each other to release 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 moving range of the driving rod 421 is limited by the blocks, and the driving rod 421 is prevented from escaping from the connecting frame 31.

[0111] On the basis of the above-mentioned implementation scheme, elastic pads, such as rubber pads, are arranged on the contact surfaces between the clamping frame 3 and the turning frame 41 and the corridor.

[0112] Based on the above implementation scheme, see Figure 7 and Figure 8 The tooth group includes a plurality of fixed teeth 422 and a movable tooth 423. The fixed teeth 422 are arranged in the vertical direction. The movable teeth 423 are arranged below the fixed teeth 422. A tooth slideway 425 is arranged on the driving rod 421. The movable teeth 423 are vertically slidably connected to the driving rod 421 through the tooth slideway 425. A support member 424 is arranged below the movable teeth 423. The support member 424 is an arc-shaped metal strip. The support member is embedded in the tooth slideway 425, and its arc-shaped portion protrudes toward the outside of the tooth slideway 425. Through the structure of this solution, the number of tooth grooves on the rotating shaft 411 is equal to the sum of the number of fixed teeth 422 and 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 flip frame 41, and after rotating to the movable teeth 423, the flip frame 41 is in a flipped-out state. When the lifting frame 1 continues to pull up and the driving rod 421 is off the ground, under the elastic support of the movable teeth 423 and the support member 424, the movable teeth 423 relies on the force of the support member 424 to resist the rotating shaft 411, so that it does not rotate, thereby maintaining the flip frame 41 in the flipped-out state.

[0114] Through the arrangement 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.
