Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to an anti-dropping device for a main truss of a hanging basket. Background Art

[0002] The hanging basket technology is the core means of cantilever continuous beam construction in modern bridge construction, especially in places where traditional support construction is not suitable, such as crossing large rivers and deep valleys. As a complex movable formwork system, the hanging basket equipment is composed of key components such as the truss system, suspension system, anchoring system, walking system, working platform and formwork system. Its working principle is that the hanging basket is suspended on the cast beam section by relying on the truss system, and moves forward section by section through a cyclic operation to achieve continuous construction of the entire cantilever beam section.

[0003] After the concrete pouring of a beam section is completed, the hanging basket needs to be transferred to the next beam section through the walking system to continue construction. In this process, the rear anchor rod of the truss system is first released, and then the rear hanging roller is flipped and fastened under the flange plate on the track by its own weight, and then the hanging basket is smoothly moved forward with the help of traction equipment such as the chain hoist or jack installed at the front end of the track. However, the truss system is crucial as the overall bearing structure of the hanging basket. When the rear anchor rod is loosened, the balance of the hanging basket's movement depends entirely on the balance between the hanging roller and the reaction force of the track.

[0004] The traditional way of traveling for the hanging basket may cause the balance to be broken in extreme cases, such as when the rear hook wheel of the hanging basket truss breaks due to a malfunction, causing the hanging basket to lose balance and tilt forward or even fall, posing a huge safety hazard to the construction site and possibly leading to a major safety accident.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

It should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] In the construction of cantilever continuous beams, the hanging basket is the key equipment for realizing the casting of beam sections one by one. It is suspended on the completed beam section through the truss system and moves forward along the track to construct the next beam section. However, in the actual walking process, once the hook wheel at the rear of the hanging basket truss acting on the lower surface of the flange plate on the track breaks due to a fault, it will directly lead to the instability of the truss system, and then cause the hanging basket to lose balance, resulting in a serious risk of tilting forward or even falling, posing a major threat to project safety.

[0029] To this end, the utility model proposes an anti-detachment device for the main truss of the hanging basket, which aims to effectively prevent the instability of the hanging basket truss in the above-mentioned fault conditions, ensure the safety and stability of the hanging basket when moving forward along the track, thereby greatly reducing the risk of major safety accidents caused by sudden accidents of the hanging basket during the construction of the cantilever continuous beam.

[0030] Combine the following Figure 1-Figure 6 The specific implementation manner of the hanging basket main truss anti-detachment device of the utility model is described.

[0031] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the utility model provides a hanging basket main truss anti-detachment device, the hanging basket main truss includes a truss lower beam 101, and the rear end of the truss lower beam 101 is provided with a rear hanging roller 102; the hanging basket main truss anti-detachment device includes a portal fixing frame 110 and a limiting frame 120, a fixing hole 111 allowing the truss lower beam 101 to pass through is provided between the portal fixing frame 110 and the limiting frame 120, the limiting frame 120 is provided with a C-shaped groove 121 with an opening facing downward, and the open end of the C-shaped groove 121 is provided with a hook structure facing inward; when the hanging basket is in a walking state, the rear hanging roller 102 cooperates with the lower surface of the upper flange plate 103 of the hanging basket walking track, and the upper flange plate 103 is located in the C-shaped groove 121.

[0032] Specifically, the anti-slip device is directly integrated into the main truss structure of the hanging basket, wherein the main truss of the hanging basket is composed of key components such as the truss lower beam 101, and the rear end of the truss lower beam 101 has been pre-installed with a conventional rear hanging roller 102, which is responsible for close contact and rolling cooperation with the lower surface of the upper flange plate 103 on the hanging basket walking track during walking, to ensure that the hanging basket moves smoothly along the track. According to the above scheme, the utility model adds an anti-slip device composed of a gantry fixing frame 110 and a limiting frame 120 on this basis. A fixing hole 111 that can accommodate the passage of the truss lower beam 101 is provided between the gantry fixing frame 110 and the limiting frame 120, so that the anti-slip device can be mounted on the truss lower beam 101. The limiting frame 120 has a C-shaped groove 121 with an opening facing downward, and a hook structure with an inward hooking function is provided at the open end of the C-shaped groove 121.

[0033] When the hanging basket is in a normal walking state, not only does the rear hanging roller 102 work normally, but the upper flange plate 103 of the hanging basket walking track is just embedded in the C-shaped groove 121, forming a second safety line. In an emergency situation where the original rear hanging roller 102 breaks or fails, the C-shaped groove 121 and its hook structure can immediately take on the task of preventing the hanging basket from derailing and avoiding its instantaneous instability and forward tilting, and quickly restore the hanging basket to a balanced state, thereby effectively preventing the occurrence of major safety accidents. The hanging basket main truss anti-detachment device of the utility model is cleverly designed and easy to install. Due to its simple structure, low processing cost and small manpower demand, it is very easy to promote and apply, greatly improving the safety factor during the cantilever continuous beam construction stage and reducing the risks caused by hanging basket walking failures.

[0034] like Figure 2 , Figure 2 and Figure 4As shown, according to a hanging basket main truss anti-detachment device provided by the utility model, the door-type fixing frame 110 and the limiting frame 120 are respectively designed as independent structural components, and are both configured with a plurality of mounting holes 112, and the door-type fixing frame 110 and the limiting frame 120 realize a detachable mounting matching structure through the mounting holes 112. Through the setting of the detachable structure, the assembly flexibility and convenience of the hanging basket main truss anti-detachment device are enhanced, which is convenient for rapid adjustment, installation or disassembly according to actual working conditions, and effectively saves construction time and cost.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to a hanging basket main truss anti-slip device provided by the utility model, in the vertical direction, the portal fixing frame 110 and / or the limiting frame 120 are provided with a plurality of mounting holes 112 to adjust the vertical height of the space in the fixing hole 111. Regardless of whether the portal fixing frame 110 has a plurality of mounting holes 112 in the vertical direction, or the limiting frame 120 has a plurality of mounting holes 112 in the vertical direction, or both have a plurality of mounting holes 112 in the vertical direction, the corresponding matching relationship between the mounting holes 112 can be changed to accurately adjust the height change of the truss lower beam 101 under different specifications or special working conditions, thereby ensuring the reasonable adaptation of the anti-slip device to the hanging basket main truss and improving the effectiveness and reliability of safety protection.

[0036] Preferably, according to a hanging basket main truss anti-detachment device provided by the utility model, in the installed state, there are at least two installation holes 112 on both sides of the portal fixing frame 110 and the limit frame 120, which are fixed by bolts, thereby enhancing the stability and bearing capacity of the overall structure of the device, ensuring that the anti-detachment device can function firmly and reliably when bearing the weight of the hanging basket main truss and the operating load.

[0037] like Figure 2 As shown, according to a main truss anti-slip device for a hanging basket provided by the utility model, in the horizontal direction, the door-type fixing frame 110 and the limiting frame 120 are each equipped with corresponding multiple columns of mounting holes 112; in the installed state, at least one mounting hole 112 in each column of mounting holes 112 is fixed by a bolt. The multiple columns of mounting holes 112 are fixed by multiple bolts, respectively, to further enhance the structural strength and safety performance of the anti-slip device.

[0038] like Figure 3As shown, according to the utility model, a main truss anti-drop device for a hanging basket is provided, and the door-type fixing frame 110 includes two side frames 113 and a top frame 114; the two side frames 113 and the top frame 114 respectively form the side and top of the fixing hole 111; and a first reinforcing plate 115 is vertically connected between the side frames 113 and the top frame 114. Through the supporting and connecting function of the first reinforcing plate 115, the overall rigidity and strength of the fixing hole 111 area are significantly improved, ensuring that when an accident occurs to the hanging basket, the anti-drop device can still effectively support and stabilize the main truss of the hanging basket.

[0039] Further, according to a hanging basket main truss anti-detachment device provided by the utility model, the top of the side frame 113 protrudes from the top frame 114, and the first reinforcing plate 115 is connected between the top protruding portion of the side frame 113 and the upper surface of the top frame 114. The first reinforcing plate 115 is arranged between the top protruding portion of the side frame 113 and the upper surface of the top frame 114, so that the first reinforcing plate 115 is prevented from interfering with the inside of the fixing hole 111 while still being able to provide a structural strength enhancement effect, which is beneficial to the cooperation between the fixing hole 111 and the truss lower beam 101.

[0040] like Figure 4 As shown, according to a main truss anti-detachment device for a hanging basket provided by the utility model, the limiting frame 120 includes two side plates 122 arranged opposite to each other, and the two side plates 122 are connected by a connecting plate 123 to enclose a C-shaped groove 121 with an opening facing downward. The connecting plate 123 plays a role of connecting and strengthening between the two side plates 122 arranged opposite to each other of the limiting frame 120, and the C-shaped groove 121 is formed by three plates, which has a simple structure and is easy to manufacture. Preferably, the number of the connecting plates 123 is two, and the distance between the two connecting plates 123 is greater than or equal to the width of the side frame 113, so that the side frame 113 can be arranged between the two connecting plates 123 when the portal fixing frame 110 and the limiting frame 120 are matched, thereby having a high shear strength.

[0041] like Figure 1 and Figure 4 As shown, according to a main truss anti-slip device for a hanging basket provided by the utility model, the hook structure preferably includes a first step portion 124 and a second reinforcing plate 125 vertically connected between the first step portion 124 and the side plate 122. The first step portion 124 can be buckled inwardly on the lower surface of the upper flange plate 103, and the second reinforcing plate 125 enhances the buckling strength of the limit frame 120 on the upper flange plate 103 of the hanging basket walking track, so that a good contact and locking state can be maintained even in extreme cases, thereby improving the reliability of the anti-slip device.

[0042] According to the main truss anti-slip device for the hanging basket provided by the utility model, a second step portion 126 is provided at the bottom of the connecting plate 123, and the distance between the second step portion 126 and the first step portion 124 is greater than the thickness of the upper flange plate 103. In use, the upper flange plate 103 is located between the second step portion 126 and the first step portion 124, ensuring that the upper flange plate 103 can have a certain floating margin in the C-shaped groove 121, so as to prevent the anti-slip device from colliding with the upper flange plate 103 due to the vibration of the main truss during the walking of the hanging basket, and can prevent the upper flange plate 103 from falling out of the anti-slip device, and can also avoid damage caused by excessive collision during normal walking.

[0043] The anti-slip device for the main truss of the hanging basket according to the preferred embodiment of the utility model is used for safety protection when the hanging basket is walking during the construction of cantilever continuous beams. The core structure of the device is closely matched with the main truss of the hanging basket, wherein the main truss of the hanging basket includes a truss lower beam 101 with a rear hanging roller 102 installed at one end. When the hanging basket is in the walking state, the rear hanging roller 102 is precisely docked with the lower surface of the upper flange plate 103 of the hanging basket walking track to ensure that the hanging basket moves stably along the track. At the same time, the upper flange plate 103 is embedded in the limit frame 120 part of the anti-slip device - the C-shaped groove 121 with the opening facing downward, and the open end of the C-shaped groove 121 is provided with an inward hook structure, which provides an extra layer of safety for the hanging basket.

[0044] The gantry fixing frame 110 and the limiting frame 120 are independently designed as detachable structural components, and are respectively equipped with a plurality of mounting holes 112, through which the two can be flexibly installed and adjusted in height. In the vertical direction, the plurality of mounting holes 112 on the gantry fixing frame 110 and / or the limiting frame 120 allow the height of the space in the fixing hole 111 to be fine-tuned as needed. In the horizontal direction, the two are each equipped with a plurality of rows of corresponding mounting holes 112, and at least one hole in each row is also fastened by bolts to ensure the overall stability of the device.

[0045] The gantry fixing frame 110 is composed of two side frames 113 and a top frame 114, which together form the side and top of the fixing hole 111. A first reinforcing plate 115 is vertically connected between the side frame 113 and the top frame 114 to further enhance the overall rigidity. The limiting frame 120 is composed of two oppositely arranged side panels 122 and a connecting plate 123 connecting the two, forming a C-shaped groove 121 with an opening facing downward. The hook structure inside the C-shaped groove 121 includes a first step portion 124 and a second reinforcing plate 125 vertically connected to the side panel 122, which is intended to more effectively constrain and guide the position of the flange plate 103 on the hanging basket walking track. In addition, a second step portion 126 is provided at the bottom of the connecting plate 123, and the distance between the second step portion 126 and the first step portion 124 is greater than the thickness of the upper flange plate 103. This can ensure that the upper flange plate 103 is firmly embedded in the limit frame 120 without falling off, and can also avoid bumps caused by excessive fitting, thereby achieving double safety protection for the hanging basket during its movement, effectively preventing accidents caused by the hanging basket tilting forward and falling, and greatly improving the safety and reliability of operations in bridge construction.
