Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building curtain wall installation, and particularly relates to a hoisting device for building curtain wall installation. BACKGROUND

[0002] With the development of modern buildings towards high-rise, large-scale and individualization, the application proportion of building curtain walls continues to rise. The curtain wall not only needs to be accurately hoisted to the installation position, but also needs to be kept in a stable state at the moment of installation - any slight shaking may cause irreversible damage such as glass collision profile, sealant misalignment. This installation requirement for "static stability" makes the end positioning stability of the hoisting device a core bottleneck restricting construction efficiency and quality.

[0003] The existing device only realizes temporary fixation by locking the lifting rope or mechanical arm after hoisting the curtain wall to the specified position, and does not establish a rigid connection with the building body. When hoisted to the specified position for installation, the curtain wall is likely to produce periodic oscillation with the hoisting point as the center, affecting rapid installation, and is likely to collide and damage itself and the remaining installed curtain walls during oscillation.

[0004] In addition, the clamping structure of the existing hoisting device for clamping and fixing the curtain wall is mostly fixed in size. For curtain walls with large thickness differences (such as single-layer glass of 10mm to double-layer hollow glass composite curtain wall of 50mm), different clamping components often need to be replaced, which not only increases the construction preparation time, but also increases the equipment cost. SUMMARY

[0005] The present application provides a hoisting device for building curtain wall installation, which aims to reduce the shaking of the curtain wall after hoisting it to the specified position and ensure the stability of the installation.

[0006] The present application is realized by the following technical scheme: a hoisting device for building curtain wall installation, comprising an upper cross beam, a lower cross beam and two longitudinal beams, the two ends of the upper cross beam and the lower cross beam are connected perpendicularly to the two longitudinal beams and are located at the upper and lower parts of the two longitudinal beams respectively, a lifting lug is connected to the upper cross beam, an installation cylinder is connected to the upper cross beam and the lower cross beam, an outer limiting plate and an inner limiting plate are connected to the installation cylinder, the outer limiting plate and the inner limiting plate can clamp the curtain wall, one end of the installation cylinder extends outward beyond the upper cross beam and the lower cross beam and is provided with a roller, the roller and the outer limiting plate are located at the two ends of the installation cylinder respectively.

[0007] Compared with the prior art, the present application has the following advantages and beneficial effects:

[0008] The mounting cylinder on the upper cross beam and the mounting cylinder on the lower cross beam are respectively connected with the outer limiting plate and the inner limiting plate, and the two cooperate to form a clamping structure for the curtain wall, which can fix the curtain wall from the horizontal direction to avoid the curtain wall from deviating or greatly shaking due to external force (such as wind force or hoisting inertia) during hoisting.

[0009] The upper cross beam, the lower cross beam and the two longitudinal beams form a frame structure, which is relatively rigid and can provide a stable support foundation for the curtain wall, reduce the shaking of the curtain wall caused by the deformation of the frame itself, and further ensure the stability during hoisting.

[0010] One end of the mounting cylinder extends out of the cross beam and is provided with a roller, when the curtain wall is hoisted to the vicinity of the designated installation position, the roller can contact the building wall or the installation track, and the roller friction is used to replace the sliding friction, which reduces the frictional resistance between the curtain wall and the installation surface, so that the curtain wall can be more smoothly adjusted to the position, the precise alignment is realized, and the shaking of the curtain wall during installation is reduced, the stability of installation is ensured, and the installation precision is improved.

[0011] Further, the mounting cylinder comprises an inner cylinder and an outer cylinder, the inner cylinder is located in the outer cylinder and axially slides with the outer cylinder, one end of the inner cylinder is located outside the outer cylinder and is connected with the outer limiting plate perpendicularly, the inner limiting plate horizontally slides with the mounting cylinder, the outer cylinder is provided with a limiting unit for locking or unlocking the inner limiting plate, and the inner cylinder and the outer cylinder are provided with a locking unit for locking or unlocking the inner cylinder.

[0012] Beneficial effects: the axial sliding of the inner cylinder and the outer cylinder can adjust the distance between the outer limiting plate and the inner limiting plate, and the horizontal sliding of the inner limiting plate can adapt to curtain wall panels of different thicknesses and sizes. It is not necessary to design a hoisting device for a specific specification of curtain wall, which reduces the frequency of equipment replacement, improves the reuse rate of the device, and saves construction cost.

[0013] After the inner cylinder and the outer cylinder are fixed by the locking unit, the position of the outer limiting plate can be stabilized to avoid loosening of the outer limiting plate due to vibration during hoisting; after the inner limiting plate is locked by the limiting unit, a rigid clamping force can be formed with the outer limiting plate to firmly fix the curtain wall from both sides.

[0014] The double locking structure (locking unit + limiting unit) in the present scheme can resist the impact of external force (such as wind force or inertial force) during hoisting, prevent the curtain wall from moving relatively within the clamping interval, and significantly reduce the shaking amplitude.

[0015] Before hoisting, the inner limiting plate can be quickly adjusted in clamping distance by sliding the inner cylinder, without disassembling parts to adapt to the size of the curtain wall, thus simplifying the early preparation process. When the curtain wall is hoisted to the vicinity of the installation position, the limiting unit can be temporarily unlocked to make the inner limiting plate slide out of the mounting cylinder, so that the curtain wall can be pulled out to be connected with the installation surface.

[0016] Further, the locking unit comprises a fixed shaft, a spring sheet and a limiting column, a plurality of limiting grooves are formed on the inner wall of the outer cylinder and are distributed along the axis of the outer cylinder;

[0017] The fixed shaft is fixed on the inner wall of the inner cylinder, the spring sheet is fixed on the fixed shaft, and the limiting column is fixed on one end of the spring sheet; a through hole is formed on the inner cylinder along a direction perpendicular to the axis of the inner cylinder, and one end of the limiting column penetrates through the through hole and is inserted into one of the limiting grooves.

[0018] Beneficial effect: When the locking unit in the scheme is locked, the elastic force of the spring sheet can push the limiting column to automatically penetrate through the through hole of the inner cylinder and be inserted into the limiting groove of the outer cylinder to form stable clamping, without the need for additional tools to complete the locking and limiting.

[0019] When unlocking, it is only necessary to pull the inner cylinder to slide along the axis of the outer cylinder to adjust the position, and the limiting column can pass over the limiting groove in the process of pulling the inner cylinder, at this time the spring sheet is compressed and deformed, and when pulling to the next limiting groove, the limiting column is inserted into the next limiting groove under the resetting action of the spring sheet to achieve the locking effect, the whole process does not need to disassemble the parts, the operation is simple and fast, greatly shortens the time of adjusting the distance between the outer limiting plates, and improves the construction efficiency.

[0020] The plurality of limiting grooves distributed along the axis on the inner wall of the outer cylinder correspond to different extension lengths of the inner cylinder, and can realize stepwise and accurate adjustment of the distance between the outer limiting plates and the inner limiting plates. Each limiting groove corresponds to a curtain wall with different thickness. For curtain walls with different thickness, the operator can select the limiting groove of the corresponding gear according to the actual size to avoid over-adjustment or insufficient adjustment, ensure that the clamping force is moderate, prevent the curtain wall from shaking due to loose clamping, and avoid damaging the surface of the curtain wall due to tight clamping.

[0021] The continuous elastic force of the spring sheet can make the limiting column always tightly fit with the inner wall of the limiting groove, so that the limiting column is not easy to come out of the limiting groove even if it is subjected to vibration or impact during hoisting, thereby ensuring the stability of the relative position of the inner cylinder and the outer cylinder and maintaining the clamping posture of the outer limiting plate.

[0022] Further, the limiting groove is a V-shaped groove, and one end of the limiting column inserted into the limiting groove is provided with a rounded corner.

[0023] Beneficial effect: When the rounded corner of the limiting column contacts the inclined side wall of the V-shaped groove, the axial thrust (force applied when adjusting the position of the inner cylinder) can be converted into a lateral component force to push the limiting column to automatically compress the spring sheet and exit the limiting groove, without the need to intentionally press the limiting column to achieve unlocking, thereby greatly reducing the operation resistance during adjustment.

[0024] After adjusting the inner cylinder position, when the spring sheet reset pushes the limiting column to insert into the new V-shaped slot, the round corner and the guiding effect of the V-shaped slot can make the limiting column automatically align with the slot and slide into the slot bottom, without precise alignment, reducing operation errors and improving adjustment efficiency.

[0025] Further, the spring sheet is V-shaped, the inner wall of the outer cylinder is symmetrically provided with the limiting slot on both sides, and the limiting column is provided with two, and the two limiting columns are respectively connected with the two ends of the spring sheet, and the two limiting columns can respectively pass through the through hole on the inner cylinder and be clamped into the corresponding limiting slot.

[0026] Beneficial effect: The two ends of the V-shaped spring sheet are respectively connected with the limiting column, when the spring sheet is deformed under force, the two ends of the limiting column can be extended out of the through hole of the inner cylinder and clamped into the symmetric limiting slot on both sides of the outer cylinder, forming a bidirectional symmetric locking. Compared with the single-point locking of the single-side limiting column, this design can make the contact force between the inner cylinder and the outer cylinder evenly distributed on both sides, avoiding the tilting of the inner cylinder or the local deformation of the outer cylinder caused by single-side force, greatly improving the stability of the locking state.

[0027] During hoisting, the axial or lateral force generated by the curtain wall shaking can be evenly transmitted to the outer cylinder through the two limiting columns, and the elastic restoring force of the V-shaped spring sheet can simultaneously apply pre-tightening force to the two limiting columns, ensuring that they are always tightly fitted with the limiting slot, effectively resisting loosening caused by vibration or impact, and reducing the risk of "unlocking".

[0028] The structure of the V-shaped spring sheet has higher elastic stiffness and deformation allowance than that of the flat spring sheet, and can provide greater restoring force under the same compression amount, ensuring that the clamping force of the limiting column and the limiting slot is more stable; at the same time, the stress distribution of the V-shaped structure is more uniform, and local fatigue fracture is not easy to occur during repeated deformation, prolonging the service life of the spring sheet.

[0029] Further, a sliding groove is formed on the outer side of the outer cylinder along the axial direction of the outer cylinder, one end of the sliding groove penetrates one side of the outer cylinder, and the inner limiting plate is in sliding fit with the sliding groove; the limiting unit comprises a fixed rod, and the inner limiting plate and one side of the sliding groove are provided with thread holes that overlap with each other, and the fixed rod is threadedly connected with the thread holes of the inner limiting plate and one side of the sliding groove.

[0030] Beneficial effect: The inner limiting plate slides along the axial sliding groove of the outer cylinder, and can be flexibly adjusted according to the height size of the curtain wall to ensure that the inner limiting plate can be clamped with the outer limiting plate to accurately clamp the curtain wall of different height specifications from the inner side of the curtain wall, thereby expanding the adaptation range of the device to the size of the curtain wall.

[0031] The design that the sliding groove penetrates one side of the outer cylinder facilitates the installation and disassembly of the inner limiting plate (such as replacing the inner limiting plate of different thickness to adapt to special curtain walls), thereby improving the maintenance convenience of the device.

[0032] The limiting unit adopts a fixed rod and a thread connection with an inner limiting plate and a sliding groove side threaded hole. Through the self-locking characteristics of the thread, the inner limiting plate can be firmly locked at the specified position of the sliding groove, avoiding displacement of the inner limiting plate due to vibration and curtain wall shaking during hoisting, and ensuring the stability of the clamping force on the curtain wall.

[0033] The locking mode of the threaded connection is simple to operate, and only needs to rotate the fixed rod to achieve locking or unlocking, without the need for complex tools, and the tightness of the threaded connection can reduce the gap, further improving the positioning accuracy of the inner limiting plate.

[0034] Further, the outer side of the outer cylinder is provided with a sliding groove along its axial direction, one end of the sliding groove penetrates one side of the outer cylinder, and the top end of the inner limiting plate is detachably connected with a sliding block, and the sliding block and the sliding groove are in sliding cooperation;

[0035] A plurality of spaced apart clamping grooves are formed in the side wall of the sliding groove, a recess is formed in the top of the sliding block, the limiting unit includes a guide block, a protruding block and a spring, the protruding block is coaxially fixedly connected with the guide block, the guide block is vertically slidingly connected with the recess, and the two ends of the spring are respectively connected with the bottom of the recess and the bottom of the guide block, and the protruding block can be clamped into the clamping groove.

[0036] Beneficial effects: The inner limiting plate slides along the sliding groove of the outer cylinder through the top sliding block, and during the adjustment process, no additional tools are needed, and only the inner limiting plate needs to be pushed to change the position, and the clamping structure of the protruding block and the clamping groove driven by the spring can realize the quick switching of "sliding-clamping": when the sliding block slides to the target position, the elastic force of the spring pushes the guide block to drive the protruding block to automatically pop out of the recess and clamp into the corresponding clamping groove, completing the locking; when unlocking, only pulling the inner limiting plate or the sliding block can make the protruding block disengage from the clamping groove and compress the spring, so that it can continue to slide. Compared with the locking mode of the threaded connection, the operation of rotating the fixed rod is omitted, the adjustment time is greatly shortened, and it is especially suitable for scenes where the position of the inner limiting plate needs to be frequently adjusted during curtain wall installation.

[0037] The design of the sliding groove penetrating one side of the outer cylinder, combined with the sliding cooperation of the sliding block and the sliding groove, facilitates the overall disassembly of the inner limiting plate, and improves the operation efficiency when maintaining or replacing parts of the device.

[0038] When the protrusion is clamped into the clamping groove, the spring always exerts an upward pre-tightening force on the guide block, so that the protrusion is tightly attached to the inner wall of the clamping groove. Even if the curtain wall shakes and vibrates during hoisting, the protrusion is not easy to disengage from the clamping groove due to slight displacement, effectively preventing the inner limiting plate from accidentally sliding. The clamping grooves are distributed along the side walls of the sliding groove (multiple spaced clamping grooves can be provided according to requirements), and the cooperation of the protrusion with different clamping grooves can achieve precise positioning of the inner limiting plate at multiple preset positions, avoiding positional deviation during adjustment and ensuring the clamping accuracy of the curtain wall with the outer limiting plate. When the protrusion is clamped into or disengaged from the clamping groove, the deformation of the spring will produce a clear "stuck feeling" or "springing feeling", and the operator can intuitively judge whether the inner limiting plate is in the locked state through tactile feedback, reducing the problem of not being locked or not being unlocked due to misoperation, and improving the safety during the hoisting process of the curtain wall.

[0039] In addition, after the curtain wall is lifted to the specified installation wall surface, the sliding block is slid towards the installation wall surface, so that one end of the sliding block abuts against the installation wall surface, and cooperates with the roller to stabilize the entire device. During the process of sliding the curtain wall out of the installation wall surface, the upper and lower sliding blocks also serve as guides and supports for the curtain wall. At this time, the sliding block acts as a bridge, allowing the curtain wall to move smoothly to the installation position, avoiding deviation from the preset installation trajectory, and providing support for the curtain wall from both sides, dispersing the gravity load of the curtain wall, and preventing the curtain wall from tilting or falling due to uneven force during movement.

[0040] The support and guiding function of the sliding block can avoid hard collision (such as edge scratching) between the curtain wall and the installation wall surface during sliding out, reducing the risk of damage to brittle materials such as curtain wall glass and stone; at the same time, the flexible abutment of the sliding block and the installation wall surface (a buffer structure such as a rubber pad can be used according to design) can also reduce damage to the installation wall surface.

[0041] Compared with manual pushing without guidance, the guiding function of the sliding block makes the curtain wall movement more controllable, reduces the probability of accidents caused by the curtain wall shaking and being difficult to control by the construction personnel, and improves the safety of the operation.

[0042] Further, the two ends of the sliding groove are respectively penetrated through the two sides of the outer cylinder, the bottom of the sliding block is vertically connected with a clamping plate, one side of the outer limiting plate facing the inner limiting plate is provided with a mounting groove, the clamping plate can be slidably clamped into the mounting groove, and the thickness of the clamping plate is less than or equal to the thickness of the mounting groove.

[0043] Beneficial effects: The cooperation of the clamping plate and the mounting groove limits the relative rotation or lateral misalignment of the inner and outer limiting plates, so that they always maintain a parallel clamping posture, especially when the curtain wall is subjected to lateral force during hoisting, they can jointly resist external force, and strengthen the overall clamping stability. Moreover, the clamping plate located in the mounting groove can avoid interference with the side of the outer limiting plate in contact with the curtain wall, so that the outer limiting plate can stably support and limit the curtain wall.

[0044] In addition, the clamping plate and the inner limiting plate are matched with each other to clamp and wrap the upper part of the curtain wall, so that when the curtain wall is lifted to a specified position, the curtain wall can be slid to the installation wall by pulling the inner limiting plate to slide to the installation wall, the distance between the curtain wall and the installation wall is shortened, and thus the curtain wall is convenient for an operator to operate, and smooth and rapid installation is realized.

[0045] Further, the bottom of the sliding block is provided with a strip-shaped groove, the side of the inner limiting plate away from the outer limiting plate is vertically connected with a connecting plate, the connecting plate is in sliding cooperation with the strip-shaped groove, and the connecting plate is provided with a fastener for detachably connecting the connecting plate to the sliding block.

[0046] Beneficial effects: in the scheme, the inner limiting plate is in sliding cooperation with the strip-shaped groove at the bottom of the sliding block through the connecting plate, so that the position of the inner limiting plate can be adjusted, the model range of curtain wall installation is further expanded, and different sizes of curtain walls can be further adapted.

[0047] Specifically, the sliding cooperation of the connecting plate and the strip-shaped groove enables the inner limiting plate to be flexibly adjusted in position along the length direction of the strip-shaped groove of the sliding block: when the thickness, width and other specifications of the curtain wall change, the distance between the inner limiting plate and the outer limiting plate (or the contact point of the curtain wall) can be changed by sliding the inner limiting plate, so that different sizes of curtain walls can be adapted without replacing the sliding block or the inner limiting plate as a whole, and the universality and application range of the device are significantly improved.

[0048] During the sliding adjustment, the strip-shaped groove guides and restricts the connecting plate, so that the moving track of the inner limiting plate is stable (such as translation in a direction perpendicular to the surface of the curtain wall), the limiting precision is prevented from being reduced due to deviation during adjustment, and the fitting degree with the curtain wall is ensured.

[0049] Further, the side of the inner limiting plate away from the outer limiting plate is connected with a pull ring, and / or the bottom of the sliding block and away from the outer limiting plate is provided with a hook groove.

[0050] Beneficial effects: in this way, the operator can hook the tool on the hook groove or the pull ring by a tool, so as to pull the inner limiting plate and the sliding block to slide, and the hook groove or the pull ring provides a control position for pulling the inner limiting plate and the sliding block to slide.

[0074] The fixed shaft 50 is fixed on the inner wall of the inner cylinder 5, in this embodiment, the fixed shaft 50 is perpendicular to the axis of the inner cylinder 5, and is integrally formed with the inner cylinder 5 or is fixed by welding or other ways, the spring sheet 51 is fixed on the fixed shaft 50, and in this embodiment, the spring sheet 51 is fixedly connected with the fixed shaft 50 by screws.

One end of the groove 40 passes through one side of the outer cylinder 4. The inner limiting plate 8 slides in conjunction with the groove 40. In this embodiment, the groove 40 is a T-shaped groove 40. The end of the inner limiting plate is a T-shaped structure that matches the shape of the T-shaped groove 40. In this way, while the inner limiting plate 8 can slide in the groove 40, the groove 40 and the inner limiting plate 8 can also play a limiting and supporting role, preventing the inner limiting plate 8 from falling off under the action of gravity.

[0079] The limiting unit in this embodiment includes a fixing rod 11. The inner limiting plate 8 and the sliding groove 40 have overlapping threaded holes on one side.

[0092] In the embodiment, the distance between the inner limiting plate 8 and the clamping plate 130 can be adjusted, the gap range between the inner limiting plate 8 and the outer limiting plate 6 can be further expanded, and thus the thickness model range of the installed curtain wall 7 to be hoisted can be expanded.

[0093] In an embodiment, as shown in Figure 1 and Figure 5As shown, the inner limiting plate 8 is connected with a pull ring 82 and / or a hook groove 132 is arranged at the bottom of the sliding block 13 and away from the outer limiting plate 6. Thus, after the curtain wall 7 is hoisted to the designated position, the inner limiting plate 8 can be conveniently pulled to slide, so that the curtain wall 7 can be conveniently removed.
