[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1:

[0029] Figure 1 A schematic structural diagram of an elevator shaft climbing device according to an embodiment of the present invention is shown; Figure 2A structural schematic diagram of the elevator shaft climbing device from another perspective in an embodiment of the present invention is shown, wherein the climbing device includes a first clamping assembly 3, a first action part 1 for adjusting the working state of the first clamping assembly 3, a second clamping assembly 4, a second action part 2 for adjusting the working state of the second clamping assembly 4, and a linkage rod assembly 5 arranged between the first action part 1 and the second action part 2. Based on the linkage rod assembly 5, the action linkage control between the first action part 1 and the second action part 2 is performed, so that the action linkage control between the first action part 1 and the second action part 2 can be performed by the linkage rod assembly.

[0030] When the first action part 1 moves toward the second action part 2 and reaches the desired position, the first action part 1 adjusts the first clamping assembly 3 to a locked state based on the linkage rod assembly 5, and the second action part 2 adjusts the second clamping assembly 4 to a released state based on the linkage rod assembly 5;

[0031] Or when the second action part 2 moves to the position away from the first action part 1, the first action part 1 adjusts the first clamping assembly 3 to the loosened working state based on the linkage rod assembly 5, and the second action part 2 adjusts the second clamping assembly 4 to the locked working state based on the linkage rod assembly 5.

[0032] The linkage rod assembly 5 drives the first action part 1 and the second action part 2 to adjust their actions, thereby achieving climbing motion control between the first action part 1 and the second action part 2.

[0033] Specifically, the first clamping assembly 3 includes: a first wedge block 31 and a first clamping block 32. The first clamping assembly 3 is provided with two first clamping blocks 32 and two first wedge blocks 31. By symmetrically arranging the two first clamping blocks 32 on both sides of the elevator guide rail, a first contour groove is formed between the first clamping block 32 and the elevator guide rail, and the shape of the first wedge block 31 matches the shape of the first contour groove. By completely fitting the first wedge block 31 in the first contour groove and cooperating with the load gravity borne by the first action part 1, a tight fit between the first wedge block 31, the first clamping block 32 and the elevator guide rail can be satisfied. A clamping state is formed based on the friction force between the first wedge block 31 and the elevator guide rail. Based on the cooperation between the first wedge block 31 of the first clamping assembly 3 and the first contour groove, the first clamping assembly 3 can meet its own locking state cooperation based on the load gravity of the first action part 1.

[0034] Furthermore, the second clamping assembly 4 is provided with a second wedge block 41 and a second clamping block 42, and a second contour groove is formed between the second clamping block 42 and the elevator guide rail. The matching relationship between the second wedge block 41, the second clamping block 42 and the elevator guide rail is the same as that of the first clamping assembly 3, and will not be repeated here.

[0035] Specifically, the first push rod group 11 is provided with two symmetrically distributed arc-shaped push rods, and the first clamping assembly 3 includes a first wedge block 31. One end of the two arc-shaped push rods is fixed on the first transmission rod 12, and the other end of the two arc-shaped push rods forms a support point of the first wedge block 31. When the first transmission rod 12 rotates, it drives the first push rod group 11 to rotate, so that the two arc-shaped push rods can connect with the bottom of the first wedge block 31 and push the first wedge block 31 to move upward, thereby ensuring that the first wedge block 31 can be completely matched in the contoured groove.

[0036] Specifically, the first action part 1 is used to regulate the working state of the first clamping assembly 3. The movement state of the first wedge block 31 of the first clamping assembly 3 is adjusted through the action of the first action part 1. When the first clamping assembly 3 needs to switch from a loose state to a clamped state, the first wedge block 31 is adjusted to move upward into the first contoured groove through the action of the first action part 1, so that the first clamping assembly 3 can form a clamping state based on the load gravity of the first action part 1.

[0037] Furthermore, when the first clamping assembly 3 switches from a clamped state to a released state, sufficient space is reserved under the first wedge block 31 of the first clamping assembly 3 through the action adjustment of the first action part 1. When the force exerted by the external power component on the first action part 1 offsets the load gravity of the first action part 1, the first wedge block 31 of the first clamping assembly 3 can drop with its own weight to achieve the unlocking operation.

[0038] Specifically, the second action part 2 is used to regulate the working state of the second clamping assembly 4. The movement state of the second wedge block 41 of the second clamping assembly 4 is adjusted by the action of the second action part 2. When the second clamping assembly 4 needs to switch from a loose state to a clamped state, the second wedge block 41 is adjusted to move upward into the second contoured groove through the action of the second action part 2, so that the second clamping assembly 4 can form a clamping state based on the load gravity of the second action part 2.

[0039] Furthermore, when the second clamping assembly 4 switches from a clamped state to a released state, the action of the second action part 2 is adjusted so that sufficient space is reserved under the second wedge block 41 of the second clamping assembly 4. When the force exerted by the external power component on the second action part 2 offsets the load gravity of the second action part 2, the second wedge block 41 of the second clamping assembly 4 can drop with its own weight to achieve the unlocking operation.

[0040] Furthermore, based on the first action part 1, the working state switching adjustment of the first clamping component 3 is performed, and the second action part 2, the working state switching adjustment of the second clamping component 4 is performed, and the linkage rod component 5 is cooperated to perform linkage control on the first action part 1 and the second action part 2, thereby realizing the automated action linkage adjustment between the first action part 1 and the second action part 2, and meeting the climbing action movement requirements between the first action part 1 and the second action part 2.

[0041] Specifically, the linkage rod assembly 5 includes: an action link 51, a first connecting rod 52 and a second connecting rod 53. The first action part 1 includes a first transmission rod 12 and a first push rod group 11 provided on the first transmission rod 12. The second action rod includes a second transmission rod 22 and a second push rod group 21 provided on the second transmission rod 22. The first push rod group 11 is provided on the first transmission rod 12. The first transmission rod 12 drives the first push rod group 11 to rotate, thereby adjusting the posture of the first push rod group 11 so that the first push rod group 11 can meet the limit support for the first clamping assembly 3. The second push rod group 21 is provided on the second transmission rod 22. The rotation of the second transmission rod 22 can drive the second push rod group 21 to deflect, thereby adjusting the posture of the second push rod group 21 so that the second push rod group 21 can provide limit support for the second clamping assembly 4.

[0042] Furthermore, one end of the action link 51 is connected to the first transmission rod 12 based on the first connecting rod 52, so that the action link 51 can move up and down with the lifting of the first action part 1, and the other end of the action link 51 is connected to the second transmission rod 22 based on the sleeve, so that the second action part 2 can move up and down along the action link 51 based on the sleeve.

[0043] Furthermore, the actuation link 51 is provided with a first spring group 6 and a second spring group 7. The first spring group 6 is provided in the middle of the actuation link 51, and the second spring group 7 is provided at the bottom of the actuation link 51. During the relative motion of the first actuation part 1 and the second actuation part 2, the cooperation between the first spring group 6 and the second spring group 7 enables the actuation link 51 to drive the first actuation part 1 and the second actuation part 2 to switch corresponding actions.

[0044] The first spring group 6 includes a first fixed block 61 and a first spring 62. The first fixed block 61 is arranged in the middle of the action link 51. The first spring 62 is sleeved on the action link 51, and one end of the first spring 62 is fixed on the first fixed block 61. The other end of the first spring 62 faces the top of the second action part 2. When the first action part 1 drives the action link 51 to move downward, the second spring group 7 can be connected to the top of the second action part 2 based on the second spring 72, so that the second spring 72 can be in a compressed state, thereby forming a speed difference between the descending rate of the action link 51 and the first action part 1, so that the action link 51 drives the first action part 1 to achieve action switching.

[0045] The second spring group 7 includes a second fixing block 71 and a second spring 72. The second fixing block 71 is provided at the bottom end of the actuating link 51. The second spring 72 is sleeved on the actuating link 51, and one end of the second spring 72 is fixed to the second fixing block 71. The other end of the second spring 72 faces the bottom of the second actuating portion 2. When the second actuating portion 2 moves downward along the actuating link 51, the bottom of the second actuating portion 2 can contact the second spring 72, driving the second spring 72 to compress. Based on the obstruction of the second spring group 7, the actuating link 51 can drive the second actuating portion 2 to achieve action switching. Based on the elastic reset of the second spring group 7, the actuating link 51 can drive the first actuating portion 1 to achieve action switching.

[0046] One end of the action link 51 is movably connected to the first link 52, and the other end of the action link 51 is movably connected to the second link 53, so that the action link 51 can drive the connection between the first action part 1 and the second action part 2 based on the first link 52 and the second link 53. Based on the relative position change between the first action part 1 and the second action part 2, the action coordination between the first action part 1 and the second action part 2 can be satisfied through the action link 51. By arranging the action link 51 between the first action part 1 and the second action part 2 for action linkage, the first action part 1 and the second action part 2 can perform linkage control of corresponding action operations during relative movement, thereby realizing the switching adjustment of the release state and the locking state of the first clamping component 3 of the first action part 1.

[0047] Specifically, the first connecting rod 52 is set as an L-shaped connecting rod, the action connecting rod 51 is movably connected to one end of the L-shaped connecting rod, and the first transmission rod 12 is connected to the middle position of the L-shaped connecting rod, so that the connection position between the first transmission rod 12 and the L-shaped connecting rod forms a support point. When the action connecting rod 51 drives one end of the L-shaped connecting rod to move, the L-shaped connecting rod can form a deflection motion around the support point, thereby driving the first transmission rod 12 to rotate. Based on the motion control of the L-shaped connecting rod in cooperation with the action connecting rod 51, convenient motion adjustment control can be achieved.

[0048] Furthermore, a first torsion spring 13 is provided at the connection position between the first connecting rod 52 and the first transmission rod 12. The first torsion spring 13 is used to provide a reset elastic force, so that the first connecting rod 52 can be reset with the elastic force of the first torsion spring 13, thereby meeting the working state switching and adjustment requirements of the first action part 1 for the first clamping assembly 3.

[0049] Furthermore, a second torsion spring 23 is provided at the connection position between the second connecting rod 53 and the second transmission rod 22. The structural design and working principle of the second torsion spring 23 are the same as those of the first torsion spring 13. For details, please refer to the working principle between the first torsion spring 13 and the first connecting rod 52, which will not be repeated here.

[0050] Furthermore, the first torsion spring 13 and the second torsion spring 23 can also be used as a buffer mechanism. The first torsion spring 13 can buffer the first wedge block 31 of the first clamping assembly 3. When the first wedge block 31 falls, the first wedge block 31 can directly act on the first push rod group 11, and the falling impact force is transmitted to the first transmission rod 12 and the first connecting rod 52 through the first push rod group 11. The first torsion spring 13 can buffer the impact force of the first wedge block 31, thereby avoiding the impact force of the first wedge block 31 causing impact damage to the first connecting rod 52 and the first transmission rod 12 during the descent of the first wedge block 31.

[0051] Furthermore, the second torsion spring 23 has the same buffering effect as the first torsion spring 13, which will not be described in detail here.

[0052] Specifically, Figure 3 It shows a schematic diagram of the action principle of the second action part 2 in the embodiment of the present invention in the downward movement; Figure 4 The schematic diagram shows the operating principle of the descending movement of the first action part 1 in an embodiment of the present invention. The descending operation principle of the climbing device is as follows: when the first action part 1 is fixed to the elevator guide rail based on the first clamping assembly 3, the second action part 2 moves downward along the elevator guide rail based on the drive of the power assembly. When the second action part 2 descends to the top of the second spring group 7, the second spring group 7 is gradually compressed under the action of the second action part 2, and the descending movement of the second action part 2 is blocked. Based on the blocking of the second spring group 7 and the descending movement of the second action part 2, the second connecting rod 53 is deflected, and the second transmission rod 22 is driven to rotate, so that the second push rod group 21 of the second transmission rod 22 is deflected upward, so that the second push rod group 21 can drive the second wedge 41 of the second clamping assembly 4 to move upward, so that the second wedge 41 can be completely fitted into the second contoured groove of the second clamping assembly 4. Based on the driving force of the power assembly acting on the second action part 2, the second clamping assembly 4 is self-locked due to the force applied to the second action part 2.

[0053] Furthermore, when the second action part 2 is in a locked and fixed state based on the second clamping assembly 4, the driving force is applied in reverse based on the power assembly, and the action link 51 moves upward based on the elastic reset of the second spring group 7, and the first connecting rod 52 is driven to deflect by the action link 51, so that the first connecting rod 52 drives the first transmission rod 12 to rotate, so that the first push rod group 11 of the first transmission rod 12 is deflected, and the first push rod group 11 is moved away from the first wedge block 31 of the first clamping assembly 3, so that there is enough space under the first wedge block 31 to meet the downward movement of the first wedge block 31.

[0054] Furthermore, based on the driving force of the power component offsetting the gravity of the first action part 1, the first wedge block 31 of the first clamping component 3 can automatically drop and disengage from the first contoured groove of the first clamping component 3, thereby realizing the unlocking operation of the first clamping component 3.

[0055] Specifically, when the first clamping assembly 3 is in an unlocked state, and the first action part 1 is in an unlocked active state based on the first clamping assembly 3, the first action part 1 is driven downward by the power assembly, so that the first action part 1 moves toward the direction of the second action part 2. When the first spring group 6 is in contact with the top of the second action part 2, the first spring group 6 is squeezed based on the second action part 2, so that the first spring group 6 is in an elastically compressed state. When the elastic pressure of the first spring group 6 is greater than the friction between the action link 51 and the first action part 1, the action link 51 moves upward based on the elastic force of the first spring 62, thereby driving the first connecting rod 52 to rotate based on the action link 51, and driving the first transmission rod 12 to rotate, so that the first push rod group 11 of the first transmission rod 12 can push the first wedge block 31 of the first clamping assembly 3 to move upward, thereby completely assembling the first wedge block 31 in the first contoured groove of the first clamping assembly 3, so that the first clamping assembly 3 is locked based on the load-bearing of the first action part 1, so that the first action part 1 is locked on the elevator guide rail based on the first clamping assembly 3.

[0056] Furthermore, when the first clamping assembly 3 is in a self-locking clamping state, the second wedge block 41 of the second clamping assembly 4 of the second action part 2 can automatically descend, so that the second clamping assembly 4 is in a loosened clamping state, so that the second action part 2 can be lifted and lowered based on the power assembly.

[0057] Specifically, the first action part 1 and the second action part 2 perform lifting movements under the power support of the power component, and cooperate with the linkage rod component 5 to switch the working states of the first action part 1 and the second action part 2. By linkage control, the first action part 1 and the second action part 2 take turns to realize unlocking and locking actions, and cooperate with the power component for lifting control, thereby realizing the climbing action between the first action part 1 and the second action part 2.

[0058] An embodiment of the present invention provides an elevator shaft climbing device, which performs action switching control on the first clamping component 3 by setting a first action part 1, and performs action switching control on the second clamping component 4 by setting a second action part 2, and realizes linkage control between the first action part 1 and the second action part 2 based on a single action link 51, so that the first action part 1 and the second action part 2 can realize linkage switching of actions based on the action link 51 during relative motion, thereby satisfying the self-weight clamping or loosening operation of the first clamping component 3 and the second clamping component 4, and realizes climbing action control by adjusting the clamping operation switching between the first clamping component 3 and the second clamping component 4 based on the mechanical structure of the action link 51, thereby improving the stability and accuracy of the climbing action control of the climbing device.

[0059] Example 2:

[0060] Figure 5 The following is a schematic diagram of the structure of a construction platform according to an embodiment of the present invention. The construction platform comprises a workbench 10, a climbing device disposed below the workbench 10, and a power assembly disposed between the climbing devices. The power assembly comprises a driving component 40, an action screw 50, a mounting plate 20, and a support plate 30. The driving component 40 is disposed on the mounting plate 20 and is drivingly connected to one end of the action screw 50. The other end of the action screw 50 is threadedly connected to the support plate 30. The action screw 50 is driven to rotate by the driving component 40, so that the support plate 30 can move up and down along the action screw 50.

[0061] Specifically, the climbing device is arranged on both sides of the mounting plate 20 and the support plate 30, and the mounting plate 20 is slidingly matched with the elevator guide rail based on the first clamping component of the climbing device, and the support plate 30 is slidingly matched with the elevator guide rail based on the second clamping component of the climbing device. The structural matching state between the mounting plate 20 and the elevator guide rail is controlled by the first clamping component, and the structural matching state between the support plate 30 and the elevator guide rail is controlled by the second clamping component, so that the mounting plate 20 and the support plate 30 perform climbing operations along with the climbing device.

[0062] Furthermore, the power assembly is provided with two actuating screws 50 . Since the two actuating screws 50 are symmetrically distributed between the mounting plate 20 and the support plate 30 , the structural connection stability of the power assembly can be improved.

[0063] Furthermore, the driving component 40 can be configured as a driving motor, and the driving component 40 can also be configured as a driving cylinder. The working stroke of the action screw 50 can be controlled by motor drive, so that the action screw 50 can meet the lifting requirements of the support plate 30 or the mounting plate 20.

[0064] Specifically, the power assembly also includes a worm gear transmission mechanism, and the driving component 40 is connected to the two action screws 50 based on the worm gear transmission mechanism, so that the driving component 40 can synchronously drive the two action screws 50 to rotate, so that the two action screws 50 can rotate synchronously to achieve the action adjustment between the mounting plate 20 and the support plate 30.

[0065] Furthermore, the support plate 30 and the mounting plate 20 are locked and loosened by the climbing device, so that when the mounting plate 20 is fixed on the elevator guide rail, the power component can drive the support plate 30 to move downward. When the support plate 30 is fixed on the elevator guide rail, the power component can drive the mounting plate 20 to move downward, thereby realizing the descending operation control of the workbench 10.

[0066] Furthermore, the operating principles of the ascending motion control and the descending motion control of the climbing device are the same, and are not described in detail here.

[0067] Specifically, the climbing device is arranged below the workbench 10, and the working platform is raised and lowered by the climbing device. When the mounting plate 20 is in a locked and fixed state and the support plate 30 is in an active state, the support plate 30 is driven downward by the driving component 40, so that the support plate 30 moves to a preset distance, and the working states of the support plate 30 and the mounting plate 20 are switched through the linkage rod assembly 5, that is, the support plate 30 is adjusted to be in a locked and fixed state, and the mounting plate 20 is switched to an active state, and the action screw 50 is driven to rotate by the driving component 40, so that the mounting plate 20 can move downward along the action screw 50.

[0068] An embodiment of the present invention provides a construction platform, which improves the reliability and stability of the climbing action of the work platform 10 by arranging a climbing device under the work platform 10, driving the climbing device to perform lifting and lowering movements based on a driving component 40 in cooperation with a screw, and realizing linkage adjustment based on a linkage rod assembly 5 between the first action part 1 and the second action part 2 of the climbing device.
