[0002] Existing elevator climbing equipment controls the lifting and lowering of the work platform by using a traction rope. This requires a support base to be installed at the top or bottom of the elevator shaft, and the traction rope is driven by a motor or cylinder. This makes the installation of the climbing equipment in the elevator shaft cumbersome. Furthermore, the traction rope control scheme, which relies on a motor or cylinder, is prone to unstable lifting and lowering control of the work platform due to program control errors or human error. At the same time, the traction rope is prone to wear and tear over a long period of use, affecting the reliability and stability of the climbing equipment control. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

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

[0030] When the first action unit 1 moves to the second action unit 2, the first action unit 1 adjusts the first clamping assembly 3 to the locking working state based on the linkage rod assembly 5, and the second action unit 2 adjusts the second clamping assembly 4 to the releasing working state based on the linkage rod assembly 5.

[0031] When the second action part 2 moves to a position away from the first action part 1, the first action part 1 adjusts the first clamping assembly 3 to a loose working state based on the linkage rod assembly 5, and the second action part 2 adjusts the second clamping assembly 4 to a 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 movements, thereby realizing the 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 31 and a first clamping block 32. The first clamping assembly 3 is provided with two first clamping blocks 32 and two first wedges 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 blocks 32 and the elevator guide rail. The shape of the first wedges 31 matches the shape of the first contour groove. By completely fitting the first wedges 31 into the first contour groove, and in conjunction with the load weight borne by the first actuating part 1, a tight fit can be achieved between the first wedges 31, the first clamping blocks 32, and the elevator guide rail. A clamping state is formed based on the friction between the first wedges 31 and the elevator guide rail. Based on the cooperation between the first wedges 31 and the first contour groove of the first clamping assembly 3, the first clamping assembly 3 can achieve its own locking state cooperation based on the load weight of the first actuating part 1.

[0034] Furthermore, the second clamping assembly 4 is provided with a second wedge 41 and a second clamping block 42. The second clamping block 42 forms a second contour groove with the elevator guide rail. The cooperation relationship between the second wedge 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 described in detail here.

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

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

[0037] Furthermore, when the first clamping assembly 3 switches from the clamping state to the releasing state, the first action part 1 adjusts the movement to leave enough space below the first wedge 31 of the first clamping assembly 3. When the force exerted by the external power component on the first action part 1 is counteracted by the load weight of the first action part 1, the first wedge 31 of the first clamping assembly 3 can descend with its own weight to achieve the unlocking operation.

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

[0039] Furthermore, when the second clamping assembly 4 switches from the clamping state to the releasing state, the movement adjustment of the second action part 2 allows sufficient space to be reserved below 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 is counteracted by the load weight of the second action part 2, the second wedge block 41 of the second clamping assembly 4 can descend with its own weight to achieve the unlocking operation.

[0040] Furthermore, based on the first action unit 1 switching and adjusting the working state of the first clamping component 3, and the second action unit 2 switching and adjusting the working state of the second clamping component 4, the linkage rod assembly 5 coordinates and controls the first action unit 1 and the second action unit 2, thereby realizing the automated action linkage adjustment between the first action unit 1 and the second action unit 2, and meeting the climbing motion requirements between the first action unit 1 and the second action unit 2.

[0041] Specifically, the linkage assembly 5 includes: an action linkage 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 disposed on the first transmission rod 12. The second action rod includes a second transmission rod 22 and a second push rod group 21 disposed on the second transmission rod 22. The first push rod group 11 is disposed on the first transmission rod 12. Based on the rotation of the first transmission rod 12, the first push rod group 11 is driven to rotate, thereby adjusting the position and orientation of the first push rod group 11 so that the first push rod group 11 can satisfy the limiting support of the first clamping assembly 3. The second push rod group 21 is disposed 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 position and orientation of the second push rod group 21 so that the second push rod group 21 can provide limiting support for the second clamping assembly 4.

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

[0043] Furthermore, the actuation linkage 51 is provided with a first spring group 6 and a second spring group 7. The first spring group 6 is located at the middle position of the actuation linkage 51, and the second spring group 7 is located at the bottom position of the actuation linkage 51. Based on the relative movement of the first actuation part 1 and the second actuation part 2, the actuation linkage 51 can drive the first actuation part 1 and the second actuation part 2 to switch corresponding actions through the cooperation between the first spring group 6 and the second spring group 7.

[0044] The first spring assembly 6 includes a first fixing block 61 and a first spring 62. The first fixing block 61 is disposed in the middle of the action linkage 51. The first spring 62 is sleeved on the action linkage 51, and one end of the first spring 62 is fixed to the first fixing 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 linkage 51 to move downward, the second spring assembly 7 can connect with 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. This creates a speed difference between the descent rate of the action linkage 51 and the first action part 1, so that the action linkage 51 drives the first action part 1 to achieve action switching.

[0045] The second spring assembly 7 includes a second fixing block 71 and a second spring 72. The second fixing block 71 is located at the bottom end of the actuating linkage 51, and the second spring 72 is sleeved on the actuating linkage 51, with one end of the second spring 72 fixed to the second fixing block 71. The other end of the second spring 72 faces the bottom of the second actuating part 2. When the second actuating part 2 moves downward along the actuating linkage 51, the bottom of the second actuating part 2 can connect with the second spring 72, causing the second spring 72 to compress. Based on the blocking effect of the second spring assembly 7, the actuating linkage 51 can drive the second actuating part 2 to switch actions, and based on the elastic return of the second spring assembly 7, the actuating linkage 51 can drive the first actuating part 1 to switch actions.

[0046] One end of the action linkage 51 is movably connected to the first link 52, and the other end of the action linkage 51 is movably connected to the second link 53. This allows the action linkage 51 to drive and connect 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 linkage 51 can satisfy the action coordination between the first action part 1 and the second action part 2. By setting the action linkage 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 corresponding action operation linkage control during relative movement, thereby realizing the switching adjustment of the first clamping component 3 of the first action part 1 between the loosening state and the locking state.

[0047] Specifically, the first connecting rod 52 is configured as an L-shaped connecting rod, and the actuating connecting rod 51 is movably connected to one end of the L-shaped connecting rod. The first transmission rod 12 is connected to the middle position of the L-shaped connecting rod, so that the connection position of the first transmission rod 12 and the L-shaped connecting rod forms a support point. When the actuating 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 L-shaped connecting rod and the actuating connecting rod 51 for motion control, 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 force, so that the first connecting rod 52 can be reset with the force of the first torsion spring 13, thereby satisfying the working state switching and adjustment requirements of the first actuating part 1 on 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. It will not be described in detail 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 31 of the first clamping assembly 3. When the first wedge 31 falls, it can directly act on the first push rod assembly 11 and transmit the impact force of the fall to the first transmission rod 12 and the first connecting rod 52 through the first push rod assembly 11. The first torsion spring 13 can buffer the impact force of the first wedge 31, thereby preventing the impact force of the first wedge 31 from causing impact damage to the first connecting rod 52 and the first transmission rod 12 during the fall.

[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 This diagram illustrates the operational principle of the descent motion of the second action unit (2 parts) in an embodiment of the present invention. Figure 4 A schematic diagram illustrating the descent principle of the first actuating part 1 in an embodiment of the present invention is shown. The descent principle of the climbing device is as follows: When the first actuating part 1 is fixed to the elevator guide rail based on the first clamping assembly 3, the second actuating part 2 moves downward along the elevator guide rail driven by the power assembly. When the second actuating 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 actuating part 2, and blocks the descent of the second actuating part 2. Based on the blocking of the second spring group 7 and the descent of the second actuating part 2, the second connecting rod 53 deflects and drives the second transmission rod 22 to rotate, causing the second push rod group 21 of the second transmission rod 22 to deflect upward. This allows the second push rod group 21 to drive the second wedge 41 of the second clamping assembly 4 to move upward, so that the second wedge 41 can completely fit into the second contour groove of the second clamping assembly 4. Based on the driving force of the power assembly acting on the second actuating part 2, the second clamping assembly 4 forms a self-locking state based on the force received by the second actuating part 2.

[0053] Furthermore, when the second action unit 2 is in a locked and fixed state based on the second clamping assembly 4, the driving force is applied in the opposite direction based on the power assembly, and the action linkage 51 moves upward based on the elastic reset of the second spring group 7. The action linkage 51 drives the first connecting rod 52 to deflect, 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 deflects, and so that the first push rod group 11 moves away from the first wedge 31 of the first clamping assembly 3, so that there is sufficient space below the first wedge 31 to meet the downward movement of the first wedge 31.

[0054] Furthermore, based on the fact that the driving force of the power component counteracts the gravity of the first action part 1, the first wedge 31 of the first clamping component 3 can automatically descend and disengage from the first contour 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 the unlocked state, and the first actuating part 1 is in the unlocked active state based on the first clamping assembly 3, the first actuating part 1 moves downward based on the power assembly, causing the first actuating part 1 to move towards the second actuating part 2. When the first spring group 6 is in contact with the top of the second actuating part 2, the second actuating part 2 compresses the first spring group 6, causing the first spring group 6 to be in an elastic compression state. When the elastic pressure of the first spring group 6 is greater than the frictional force between the actuating linkage 51 and the first actuating part 1, the actuating linkage 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 actuating linkage 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 31 of the first clamping assembly 3 to move upward, thereby fully assembling the first wedge 31 into the first contour groove of the first clamping assembly 3, so that the first clamping assembly 3 forms a locking state based on the load of the first actuating part 1, and the first actuating part 1 is locked on the elevator guide rail based on the first clamping assembly 3.

[0056] Furthermore, when the first clamping component 3 is in a self-locking clamping state, the second wedge 41 of the second clamping component 4 of the second action unit 2 can automatically descend, so that the second clamping component 4 is in a loosened clamping state, and the second action unit 2 can perform lifting and lowering operations based on the power component.

[0057] Specifically, under the power support of the power assembly, the first acting part 1 and the second acting part 2 perform lifting movement, and cooperate with the linkage rod assembly 5 to switch the working states of the first acting part 1 and the second acting part 2. The unlocking and locking actions of the first acting part 1 and the second acting part 2 are alternately realized through linkage control, and lifting control is performed in cooperation with the power assembly, thereby realizing the climbing movement between the first acting part 1 and the second acting part 2.

[0058] The embodiment of the present invention provides an elevator shaft climbing device, wherein by arranging the first acting part 1 to perform action switching control on a first clamping assembly 3, and arranging the second acting part 2 to perform action switching control on a second clamping assembly 4, and the linkage control between the first acting part 1 and the second acting part 2 is realized based on a single action linkage rod 51, so that the first acting part 1 and the second acting part 2 can realize linkage switching of actions during relative movement based on the action linkage rod 51, thereby satisfying the self-weight clamping or releasing operations of the first clamping assembly 3 and the second clamping assembly. Through the mechanical structure of the action linkage rod 51, the switching of the clamping operation between the first clamping assembly 3 and the second clamping assembly 4 is adjusted, the climbing action control is realized, and the stability and accuracy of climbing action control of the climbing device are improved.

[0059] Embodiment 2:

[0060] Figure 5 shows a schematic structural view of a construction platform in an embodiment of the present invention. The construction platform comprises: a working table (10), a climbing device arranged below the working table (10), and a power assembly arranged between the climbing devices. The power assembly comprises: a driving component (40), an action screw rod (50), a mounting plate (20) and a support plate (30). The driving component (40) is arranged on the mounting plate (20), the driving component (40) is in driving connection with one end of the action screw rod (50), and the other end of the action screw rod (50) is threadedly connected to the support plate (30). The driving component (40) drives the action screw rod (50) to rotate, so that the support plate (30) can move up and down along the action screw rod (50).

[0061] Specifically, the climbing device is arranged on both sides of the mounting plate (20) and the support plate (30), the mounting plate (20) is in sliding fit with the elevator guide rail based on the first clamping assembly of the climbing device, and the support plate (30) is in sliding fit with the elevator guide rail based on the second clamping assembly of the climbing device. The structural fit state between the mounting plate (20) and the elevator guide rail is controlled by the first clamping assembly, and the structural fit state between the support plate (30) and the elevator guide rail is controlled by the second clamping assembly, so that the climbing operation is performed between the mounting plate (20) and the support plate (30) 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 drive motor, or it can be configured as a drive cylinder. The working stroke of the actuating screw 50 can be controlled by the motor drive, so that the actuating screw 50 can meet the lifting and lowering requirements of the support plate 30 or the mounting plate 20.

[0064] Specifically, the power assembly also includes a worm gear transmission mechanism. The drive component 40 is connected to the two actuating screws 50 through the worm gear transmission mechanism, so that the drive component 40 can synchronously drive the two actuating screws 50 to rotate, thereby achieving the adjustment of the movement between the mounting plate 20 and the support plate 30.

[0065] Furthermore, by locking and unlocking the support plate 30 and the mounting plate 20 through the climbing device, when the mounting plate 20 is fixed to the elevator guide rail, the power component can drive the support plate 30 to move downward. When the support plate 30 is fixed to the elevator guide rail, the power component can drive the mounting plate 20 to move downward, thereby realizing the descent operation control of the workbench 10.

[0066] Furthermore, the working principle of the ascending motion control of the climbing device is the same as that of the descending motion control, and will not be described in detail here.

[0067] Specifically, the climbing device is located below the workbench 10. The climbing device controls the lifting and lowering of the workbench. When the mounting plate 20 is in a locked and fixed state and the support plate 30 is in a movable state, the drive component 40 drives the support plate 30 to move downwards. After the support plate 30 moves to a preset distance, the linkage rod assembly 5 switches the working states of the support plate 30 and the mounting plate 20. That is, the support plate 30 is adjusted to a locked and fixed state, and the mounting plate 20 is switched to a movable state. The drive component 40 drives the actuating screw 50 to rotate, so that the mounting plate 20 can move downwards along the actuating screw 50.

[0068] This invention provides a construction platform. By setting up a climbing device under the workbench 10, the climbing device is driven by a drive component 40 in conjunction with a screw to perform lifting and lowering movements. The linkage adjustment is achieved based on the linkage rod assembly 5 between the first action part 1 and the second action part 2 of the climbing device, thereby improving the reliability and stability of the climbing movement of the workbench 10.

[0069] Furthermore, the above provides a detailed description of the elevator shaft climbing device and construction platform provided by the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
