Description

Technical Field

[0001] The invention belongs to the technical field of highway bridge crash wall construction, and specifically relates to a viaduct crash wall steel formwork installation trolley and a matching hanging basket and a use method. Background Art

[0002] The crash wall formwork trolley is a special construction trolley that integrates electric hoisting and side operation hanging basket platform. It is used for the hoisting, transportation, installation and disassembly of the crash wall formwork of highway bridges. It can realize the overall mold installation, demoulding, cleaning, mold release agent application, lifting and other tasks of the crash wall formwork, eliminating repeated template assembly and disassembly work, and can quickly dismantle, move and install the bridge crash wall as a platform equipment;

[0003] However, the structure of the traditional anti-collision wall installation trolley is similar to that of a lever. If there is sudden weather such as strong winds and rain during the construction process, the rain will cause insufficient friction of the anti-collision wall installation trolley tires. The strong wind will exert a thrust on the same side of the trolley and the hanging basket. If the counterweight is not added in time, the construction trolley will overturn and cause a major safety accident. At the same time, the traditional anti-collision wall installation trolley needs to directly cross the hanging basket railing to get on and off, which is inconvenient, lacks safety guarantees, and has great safety hazards.

[0004] After searching, an invention with publication number CN115874530B provides a crash-proof wall formwork trolley with a large telescopic safety platform, which relates to a crash-proof wall formwork trolley, including a vehicle body, on which two groups of support beams are installed through brackets, and two groups of platform frame groups are distributed at both ends of the support beams; each group of platform frame groups includes two groups of external supports and a platform support located between the two groups of external supports, and the two groups of external supports are correspondingly sleeved on the two groups of support beams, and are driven by a driving unit to move laterally along the support beams; but the trolley is large in size, lacks safety protection for staff and is inconvenient to move. Summary of the invention

[0005] In order to solve the problem that the traditional viaduct crash wall formwork installation trolley and matching hanging basket are insufficiently resistant to side wind and sudden rainfall and are prone to overturning and shaking, the present invention proposes an viaduct crash wall steel formwork installation trolley and matching hanging basket and a use method.

[0006] A viaduct anti-collision wall steel formwork installation trolley and a matching hanging basket, comprising a steel structure body, the steel structure body is a wide square body, a counterweight is arranged inside the steel structure body, the counterweight is located on one side of the steel structure body, a trolley driving position is installed on the other side of the steel structure body, a roof is installed on the top of the steel structure body, a hanging basket limiting rod is installed on the side of the steel structure body close to the trolley driving position, and the hanging basket limiting rod runs through one side of the steel structure body; the steel structure body as a whole can be used as a partial counterweight, a steel beam on one side of the steel structure body extends out to form a cantilever structure, a part of the hanging basket limiting rod is cantilevered, and an inclined beam is arranged at the connection between the cantilever and the hanging basket limiting rod to connect the main part of the hanging basket The downward gravity of the steel structure car body and the hanging basket limit rod is dispersed and transmitted to disperse the load to avoid long-term concentration on a single structural beam. A crane is installed between the steel structure car body and the hanging basket limit rod, and the bottom of the hanging basket limit rod is movably connected with the hanging basket body; through the cantilever structure of the steel structure car body, most of the overall device is located on the viaduct, and the center of gravity of the trolley is low and close to the center of the bridge body, which enhances the resistance to side wind. Not only the weight of the hanging basket and the hanging basket limit rod is borne by the cantilever structure, but the pulling rod also bears part of the weight of the hanging basket and the hanging basket limit rod, which reduces the pressure of the cantilever structure. There is more space inside the wide steel structure car body, which can store more counterweights to deal with emergencies.

[0007] Furthermore, the bottom of the basket limit rod passes through the four corners of the basket main frame, and the basket main body is surrounded by fences. The basket main body is equipped with a rear protection rod, and the rear protection rod is located on the side of the basket main body fence away from the steel structure body, and the rear protection rod is located above the basket main body fence; on the one hand, the basket limit rod cooperates with the basket limiter to limit the descending height of the basket main body, and on the other hand, it serves as a moving track of the basket main body to enable the basket to move along the basket limit rod. Furthermore, when encountering side winds, the basket can effectively limit the shaking of the basket and improve stability. Fences are installed to prevent workers from falling. Since the construction workers' working surface faces the viaduct, they cannot perceive the distance behind them well. Setting a rear protection rod can effectively protect the construction workers from falling backwards.

[0008] Furthermore, a safety door is installed on the main body of the hanging basket, and the hanging basket limiting rods include a plurality of the hanging basket limiting rods, which are symmetrically installed on both sides of the hanging basket main body and the steel structure body;

[0009] Furthermore, wheels are installed at the bottom of the steel structure body, the wheel on the side away from the trolley driving position is equipped with a drive motor, and the wheel on the side close to the trolley driving position is equipped with a steering motor.

The hanging basket control box is electrically connected to the hanging basket drive motor, and the hanging basket control box is electrically connected to the crane. The movement of the anti-collision wall template is directly controlled by the hanging basket control box, which facilitates the construction of the workers in the hanging basket and improves the construction efficiency.

[0013] Furthermore, the safety door is movably connected to the main body of the hanging basket, the safety door is retractable, the ceiling is made of colored steel tiles, and a drainage ditch is provided at the edge of the ceiling; the safety door can be lowered and retracted into a stepping plate as a passage for staff to enter and exit the hanging basket, and there is no need to climb over the fence like a traditional hanging basket, which greatly improves safety. A roof is set at the top to shelter from wind and rain and improve resistance to sudden weather. At the same time, a drainage ditch is provided to discharge rainwater along both sides of the edge of the ceiling to prevent rainwater from gathering and impacting the hanging basket downward, affecting the construction of staff inside the hanging basket.

[0014] A method for using a viaduct anti-collision wall steel formwork installation trolley and a matching hanging basket, comprising the following steps:

[0015] S1. Inspection: Check whether the steel structure is damaged, whether the wheel pattern and tire pressure are normal, whether the motors and chains move smoothly, whether the main body of the hanging basket can rise and fall normally, calculate the counterweight, and place enough counterweight inside the steel structure to ensure that the counterweight can cope with emergencies;

[0016] S2. Install the anti-collision wall template: install the anti-collision wall template on the crane, open the safety door, lower the safety door, and extend it under the action of gravity to become a stepping board. The staff enters the hanging basket and puts away the safety door. After the safety door is put away, it is put away under the action of gravity and becomes part of the fence;

[0017] S3, movement: The staff enters the trolley driving position and uses the steering wheel to control the trolley to move. After reaching the designated position, the driving motor and steering motor are locked in fixed position through the control panel;

[0018] S4, hanging basket descent construction: the staff controls the hanging basket to descend through the hanging basket control box inside the hanging basket, the electric hoist and the hanging basket drive motor are started at the same time, and cooperate with each other to control the hanging basket to descend. When the hanging basket descends, the bottom of the hanging basket limit rod is used as a track, and the hanging basket moves downward along the bottom of the limit rod. During the descent process, the hanging basket limiter limits the maximum descent distance of the hanging basket. After the hanging basket descends to the specified position, the electric hoist and the hanging basket drive motor are locked and a signal is sent to the hanging basket control box to remind the construction personnel that they have arrived at the specified position and start construction;

[0019] S5, hanging basket rises and trolley moves: After the anti-collision wall formwork is installed, the staff controls the hanging basket to rise through the hanging basket control box. After rising to the initial position, the staff releases the lock of the drive motor and the steering motor and moves to the next construction location. After installing the anti-collision wall formwork, repeat steps S4-S5 until all construction is completed.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The wide-body steel structure vehicle body has a large internal space and can be equipped with more counterweights to cope with emergencies. A steel beam extends from one side of the steel structure vehicle body to form a cantilever structure, which cantilever part of the basket limit rod. At the same time, an inclined beam is set at the connection between the cantilever and the basket limit rod to disperse the downward gravity of the basket body and the basket limit rod to avoid long-term concentration on a single structural beam. Through the coordination of the cantilever structure of the steel structure vehicle body and the wide-body steel structure vehicle body, most of the trolley is located on the viaduct, and only a small part of the cantilever structure extends out of the viaduct. The center of gravity of the trolley is low and close to the center of the bridge body, which enhances the resistance to side winds. At the same time, the inclined beam plays the role of a side pull rod. Not only does the cantilever structure bear the weight of the basket and the basket limit rod, but it also reduces the pressure on the cantilever structure.

[0022] The basket limit rod is set to cooperate with the basket limiter to limit the descent height of the basket body on the one hand, and on the other hand, it serves as the moving track of the basket body to limit the movement of the basket and limit the shaking of the basket when encountering side winds to improve stability. Fences are installed to prevent workers from falling. Since construction workers face the direction of the viaduct when working, they cannot perceive the distance behind them well. Setting a rear protective rod can effectively protect construction workers from falling backwards.

[0023] The trolley can move by itself without the need for an additional traction vehicle to help it move, thus avoiding congestion on the construction site. By using steering wheel control, workers can better adapt to and perceive the moving distance.

[0024] The safety door can be lowered and retracted into a stepping stone as a passage for staff to enter and exit the hanging basket. There is no need to climb over the fence like in traditional hanging baskets, which greatly improves safety. A roof is set at the top to shelter from wind and rain and improve resistance to sudden weather emergencies. At the same time, drainage grooves are set to discharge rainwater along both sides of the ceiling edge to prevent rainwater from gathering and impacting the hanging basket downward, affecting the construction of staff inside the hanging basket.
