Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a climbing device for a sea-crossing main tower formwork construction platform. Background Art

[0002] In construction, especially in high-rise building construction, offshore platform construction, canyon bridge construction and super-high bridge pier foundation construction, the formwork construction platform is an important temporary structure, and its stability and safety are crucial to the entire construction process. The climbing mechanism of the formwork construction platform is a key component to ensure that the construction platform can move vertically or obliquely along the building wall or specific structure.

[0003] The hydraulic system and reversing device of the traditional formwork construction platform are designed between the guide rail and the column. However, a significant problem with this design is that the guide rail is far away from the structural surface (such as the building wall or a specific structure), and there is also a large distance between the column and the guide rail, resulting in poor stability of the entire formwork and being easily affected by wind.

[0004] The shortcomings of this design are particularly prominent in scenarios with strong winds, such as offshore construction, canyon bridge construction, and ultra-high bridge pier foundation construction. Due to the influence of wind, the columns will sway in multiple directions in the horizontal and vertical directions when climbing along the guide rails. This sway not only reduces construction efficiency, but also increases the risks during the construction process.

[0005] Especially in the construction of offshore construction platforms, the influence of sea breeze is particularly significant, and the stability of the formwork platform is directly related to the safety of construction workers and the protection of construction equipment. Similarly, in the construction of canyon bridges and ultra-high bridge pier foundations, due to the complex terrain, the influence of wind may also cause the instability of the formwork platform, thus bringing great safety hazards to the construction. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the utility model provides a climbing device for a cross-sea main tower formwork construction platform to solve the problem that the traditional formwork is prone to shaking during the climbing process and is not suitable for use in scenarios with strong winds.

[0007] The utility model solves the above technical problems with the following technical solutions: a climbing device for a cross-sea main tower formwork construction platform, comprising a hanging seat fixed on a formed concrete foundation, a guide rail fixed to the hanging seat and arranged along the climbing direction of the formwork platform, a load-bearing tripod capable of climbing along the guide rail, and a climbing mechanism for driving the load-bearing tripod to move;

[0008] The load-bearing tripod comprises two groups of upright posts wrapped around two sides of the guide rail, a tripod crossbeam hinged on the upright posts, and a diagonal brace hinged between the upright posts and the tripod crossbeam.

[0009] Based on the above technical solutions, the present utility model can be further improved as follows.

[0010] Furthermore, upper and lower limit seats that are slidably engaged with the guide rail are respectively installed at the top and bottom of the column.

[0011] Furthermore, a first guide rail limiting portion adapted to the outer edge of the guide rail is formed on the inner sides of both the upper limit seat and the lower limit seat.

[0012] Furthermore, a detachable hanging seat load-bearing pin is inserted horizontally into the hanging seat, and a hook that can be hung on the hanging seat load-bearing pin is further formed on the upper limit seat.

[0013] Furthermore, an attached wall safety pin that extends horizontally above the upper limit seat is inserted into the hanging seat.

[0014] Furthermore, a second guide rail limiting portion adapted to the inner edge of the guide rail is formed on the inner side of the hanging seat.

[0015] Furthermore, a guide rail load-bearing pin is inserted horizontally through the guide rail, and the guide rail is supported on the hanging seat through the guide rail load-bearing pin.

[0016] Furthermore, a detachable guide rail safety pin is inserted horizontally between the guide rail and the column.

[0017] Furthermore, the climbing mechanism includes an upper reversing box and a lower reversing box; the upper reversing box is connected to the upper limit seat, and an oil cylinder is provided between it and the lower reversing box.

[0018] Furthermore, a deflectable tongue is installed in both the upper reversing box or the lower reversing box. A plurality of climbing form slots arranged at intervals are formed along the length direction of the guide rail. Support surfaces that can be adapted to the climbing form slots are formed on both the upper and lower sides of the tongue; a handle connected to the tongue, and a resilient telescopic rod that elastically supports the handle are further provided in the upper reversing box or the lower reversing box. The handle can adjust the deflection of the tongue so that the upper or lower support surface is locked with the climbing form slot of the guide rail.

[0019] Moreover, the climbing device of the cross-sea main tower formwork construction platform provided by the present utility model has at least the following beneficial effects compared with the prior art:

[0020] 1) By designing the column to enclose the guide rail, the column can fit more closely to the guide rail, greatly reducing the distance between the column and the guide rail. This close-fitting design not only reduces the sway under the action of external factors such as wind force, but also decreases the distance between the load-bearing tripod and the structure, thus significantly improving the overall stability of the formwork platform. Especially in offshore construction, canyon bridge construction, and special high pier foundation construction, this design can effectively resist the influence of sea breeze, canyon wind, and wind force during pier construction, reduce the sway of the formwork platform, and ensure construction safety and the stability of construction equipment.

[0021] 2) By precisely controlling the climbing of the load-bearing tripod along the guide rail through the climbing mechanism, efficient and stable climbing operation of the formwork platform is achieved, greatly improving the efficiency and safety of building construction. Through precise guiding and stable support designs, such as the upper limit seat, lower limit seat, and guide rail limit part, etc., the accuracy and stability of the formwork platform during climbing are ensured.

[0022] 3) Innovative designs such as the load-bearing tripod structure and climbing mechanism are adopted, improving the load-bearing capacity and climbing efficiency of the formwork platform. Through double locking mechanisms (hanging seat load-bearing pin and wall-attached safety pin), guide rail load-bearing pin and guide rail safety pin, etc., the stability and safety of the formwork platform are further enhanced.

[0031] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0032] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0033] As Figure 1 and Figure 2 shown, a climbing device for a climbing formwork construction platform of a cross-sea main tower mold designed by the present utility model includes a hanging seat 1 fixed on a formed concrete foundation, a guide rail 2 fixed on the hanging seat 1 and arranged along the climbing direction of the formwork platform, a load-bearing tripod 3 that can climb along the guide rail 2, and a climbing mechanism 4 for driving the load-bearing tripod 3 to move.

[0034] The load-bearing tripod 3 includes two groups of columns 3.1 wrapped on both sides of the guide rail 2, a tripod cross beam 3.2 hinged to the columns 3.1, and a diagonal brace 3.3 hinged between the columns 3.1 and the tripod cross beam 3.2.

[0035] The device is first fixed on the formed concrete foundation through the hanging seat 1, providing a stable support point for the entire climbing system.

[0036] As a supplement, the hanging seat 1 is fixed on the wall-attached seat 11 pre-installed on the concrete foundation.

[0037] The guide rail 2 is installed on the hanging seat 1 along the climbing direction of the formwork platform. The guide rail 2 provides a climbing path for the load-bearing tripod 3. The load-bearing tripod 3 is composed of two groups of columns 3.1, a tripod cross beam 3.2, and a diagonal brace 3.3 located on both sides of the guide rail 2 respectively. This tripod structure ensures that it can bear the weight of the formwork platform and maintain stability.

[0038] The column 3.1, as the main supporting part of the tripod, is fixed on the guide rail 2.

[0039] The cross beam 3.2 of the tripod is connected to the column 3.1 by means of hinge, and is used to support the formwork platform

[0040] The diagonal brace 3.3 is hinged between the column 3.1 and the cross beam 3.2 of the tripod, and is used to enhance the overall stability of the tripod.

[0041] The climbing mechanism 4 is responsible for driving the load-bearing tripod 3 to move upward along the guide rail 2. By controlling the climbing mechanism 4, the precise climbing of the load-bearing tripod 3 can be achieved, so as to drive the formwork platform to climb together.

[0042] When the climbing mechanism 4 drives the load-bearing tripod 3 to rise, the formwork platform also rises accordingly. This climbing method can ensure that the formwork platform can climb efficiently and stably during the building construction process.

[0043] In this embodiment, by shortening the distance between the column 3.1 and the guide rail 2, the column can fit more closely on the guide rail, and the interaction force between the two is greatly enhanced. This design not only improves the overall strength of the formwork platform, but also significantly reduces the sway under the action of external factors such as wind. This improvement enables the column and the guide rail to provide bearing capacity at the same time, thus ensuring the stability of the entire formwork platform.

[0044] The climbing device of this cross-sea main tower formwork construction platform significantly improves the stability of the formwork platform while ensuring the climbing function, especially in the environment with strong wind or other complex conditions.

[0045] As an implementation method, as Figure 1 and Figure 3 shown, upper limit seats 5 and lower limit seats 6 that are slidably matched with the guide rail 2 are respectively installed at the top and bottom of the column 3.1. They are slidably matched with the guide rail 2, providing precise guidance and stable support for the column 3.1.

[0046] Specifically, guide rail limiting parts 5.1 that are adapted to the outer edge of the guide rail 2 are formed on the inner sides of the upper limit seat 5 and the lower limit seat 6 respectively, so that when the column 3.1 climbs along the guide rail 2, it can maintain a precise position and direction, ensuring that the column 3.1 always keeps close contact with the guide rail 2 during the whole climbing process, and avoiding deviation or sway.

[0047] In addition, a detachable hanging seat load-bearing pin 7 is inserted horizontally into the hanging seat 1, and a hook 5.2 that can be hung on the hanging seat load-bearing pin 7 is also formed on the upper limit seat 5. The hanging seat 1, as the fixed foundation of the whole climbing device, provides stable support and fixed points for the column 3.1 and the load-bearing tripod 3 thereon through the horizontally inserted detachable hanging seat load-bearing pin 7.

[0048] When the formwork climbing frame reaches the in-place position, the hook 5.2 is fixed by the hanging seat load-bearing pin 7, and the column 3.1 and the load-bearing tripod 3 thereon are locked in a specific position to ensure its stability in the static state.

[0049] As an implementation manner, an attached wall safety pin 8 extending horizontally above the upper limit seat 5 is also inserted into the hanging seat 1.

[0050] When the formwork climbing frame climbs to the in-place position through the climbing mechanism and the hook 5.2 is preliminarily fixed by the hanging seat load-bearing pin 7, the attached wall safety pin 8 is inserted into the hanging seat 1 and extends horizontally above the upper limit seat 5. This step provides secondary locking for the upper limit seat 5 and further enhances the stability of the column 3.1 and the load-bearing tripod 3 thereon.

[0051] As an implementation manner, a second guide rail limiting portion 1.1 adapted to the inner edge of the guide rail 2 is further formed inside the hanging seat 1. The close fit between the second guide rail limiting portion 1.1 and the guide rail 2 provides stable support for the hanging seat 1.

[0052] In addition, a guide rail load-bearing pin 9 is inserted through the guide rail 2 in the horizontal direction, and the guide rail 2 is carried on the hanging seat 1 through the guide rail load-bearing pin 9.

[0053] The guide rail load-bearing pin 9 is a key component connecting the guide rail 2 and the hanging seat 1. It is inserted through the guide rail 2 in the horizontal direction and stably carries the guide rail 2 on the hanging seat 1. This design enables the guide rail 2 to bear the weight from the load-bearing tripod 3 and other loads on the formwork construction platform.

[0054] As an implementation manner, a detachable guide rail safety pin 10 is inserted horizontally between the guide rail 2 and the column 3.1. The guide rail safety pin 10 uses a pin shaft and a bolt to establish the connection and locking between the guide rail 2 and the column 3.1.

[0055] The guide rail safety pin 10 is inserted horizontally through the preset holes of the guide rail 2 and the column 3.1, and tightly fixes them together. The insertion of the guide rail safety pin 10 effectively prevents the relative displacement between the guide rail 2 and the column 3.1, thereby enhancing the stability of the entire climbing device in the static state. This fixing method can ensure that the guide rail and the column still maintain a stable positional relationship under the influence of wind force, vibration or other external factors.

[0056] As an implementation manner, such as Figure 4 and Figure 5As shown, the climbing mechanism 4 includes an upper reversing box 4.1 and a lower reversing box 4.2; the upper reversing box 4.1 is connected to the upper limit seat 5, and an oil cylinder 4.3 is arranged between it and the lower reversing box 4.2. In the climbing mechanism 4 of the formwork construction platform, the upper reversing box 4.1 is connected to the lower limit seat 5, and relative movement with the lower reversing box 4.2 is achieved through the oil cylinder 4.3. Among them, the tongue 4.4 is a key component, and its deflection is used to lock with the climbing form groove on the guide rail 2.

[0057] Specifically, a deflectable tongue 4.4 is installed in both the upper reversing box 4.1 or the lower reversing box 4.2. The guide rail 2 is provided with a plurality of climbing form grooves arranged at intervals along the length direction. Support surfaces that can be adapted to the climbing form grooves are formed on both the upper and lower sides of the tongue 4.4; a handle 4.5 connected to the tongue 4.4, and a resilient telescopic rod 4.6 that elastically supports the handle 4.5 are also provided in the upper reversing box 4.1 or the lower reversing box 4.2. The handle 4.5 can adjust the deflection of the tongue 4.4 so that the upper or lower support surface locks with the climbing form groove of the guide rail 2.

[0058] By operating the handle 4.5, the deflection angle of the tongue 4.4 can be adjusted so that the upper or lower support surface thereof aligns with the climbing form groove of the guide rail 2. After the support surface of the tongue 4.4 aligns with the climbing form groove, the tongue will closely fit with the climbing form groove due to the push of the oil cylinder 4.3 or its own gravity, achieving locking.

[0059] Before the tongue 4.4 locks with the climbing form groove, the resilient telescopic rod 4.6 will provide sufficient elastic force to ensure that the tongue can be smoothly deflected to the required position. After the tongue locks with the climbing form groove, the resilient telescopic rod will also provide a certain holding force to ensure the stability of the locking.

[0060] The oil cylinder 4.3 drives the relative movement between the upper reversing box 4.1 and the lower reversing box 4.2 through the telescopic movement of its piston rod, thereby driving the tongue 4.4 to lock or unlock with the climbing form groove of the guide rail 2.

[0061] The oil cylinder 4.3 starts to work, pushing the relative movement between the upper reversing box 4.1 and the lower reversing box 4.2, so that the formwork construction platform climbs along the guide rail 2.

[0062] After the formwork construction platform reaches a new position, operate the handle 4.5 again to lock the support surface of the tongue 4.4 with the climbing form groove at the new position, ensuring that the formwork construction platform remains stable at the new position.

[0063] The elastic telescopic rod 4.6 is assembled by a spring, a spring top sleeve and a spring bottom sleeve. The spring top sleeve can slide relative to the spring bottom sleeve, and the spring elastically supports within the spring top sleeve and the spring bottom sleeve. When it is necessary to adjust the deflection angle of the tongue 4.4, by operating the handle 4.5, the spring top sleeve slides relative to the spring bottom sleeve. During this process, the spring is compressed or stretched, thereby providing the necessary elastic force.

[0064] As an implementation manner, during the construction process of the die carrier, due to the possible inclination of the concrete foundation and the possible curvature of the wall surface, the traditional fixing method may not ensure the stability and safety of the construction platform. In this embodiment, a tail support 12 in contact with the wall surface is also installed on the lower limit seat 6 to provide additional support and stability.

[0065] The tail support 12 consists of a telescopic rod body and a contact surface. The length of the rod body is adjusted by a screw to meet the requirements of different wall heights and angles. The contact surface is designed with a certain curvature to better adapt to the wall surface curvature and ensure close contact between the tail support and the wall surface.

[0066] The design of the tail support 12 can enhance the overall stability of the construction platform, reduce the unstable factors caused by the inclination of the concrete foundation or the curvature of the wall surface, and improve the construction safety.

[0067] As an implementation manner, as Figure 6 shown, on the side of the column 3.1 close to the wall surface, a section steel assembly hole 3.4 is also reserved. After climbing in place, nuts can be welded at the section steel assembly hole 3.4, and the guide rail 2 and the column 3.1 are locked by assembling the section steel to ensure the locking stability and improve the overall strength.
