Description

Technical Field

[0001] The invention relates to equipment and a method for assisting the processing of a crash wall, in particular to a multifunctional crash wall construction trolley and a crash wall construction method thereof. Background Art

[0002] As an auxiliary structure of the bridge, the crash wall is generally cast with concrete. The traditional crash wall construction generally relies on manpower or the use of a trolley to assist in casting with a single set of formwork (1-1.5 meters long). After the casting is completed, the set of formwork is disassembled, moved, and then installed. When using the traditional trolley-assisted crash wall casting method, the trolley can only be moved after the concrete solidifies, which greatly limits the use of the trolley. In addition, the crash wall is constructed with a single set of formwork. During the entire construction process, there are many template splicing, assembly, and disassembly, which is time-consuming and labor-intensive, and inefficient. In addition, the templates are misaligned and have large gaps when splicing, resulting in poor casting quality. Summary of the invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a crash wall trolley and a crash wall construction method with reasonable design, simple structure and easy use. The trolley can lift a group of formwork (up to 12 meters long) at one time and move them in multiple directions, and can cast multiple groups of formwork at the same time for cyclic construction. During the casting process, the trolley can be detached from the formwork being cast to lift and erect other formworks, thus overcoming the shortcomings of traditional single-group formwork assembly and casting, and improving construction efficiency and casting quality.

[0004] The present invention is implemented in this way: a multifunctional anti-collision wall construction trolley is constructed, comprising a load-bearing platform and a main truss installed on the upper end of the load-bearing platform, a hanger is installed on the outer side of the main truss, and a template hoisting mechanism for hoisting the anti-collision wall template and capable of driving the anti-collision wall template to move outward or inward is arranged below the hanger;

[0005] The main truss is provided with a hanger lifting device on the outside to drive the hanger to move up and down;

[0006] A walking mechanism is installed at the lower end of the bearing platform, and a counterweight block is installed at the upper end.

[0007] Preferably, it also includes a lifting and lowering hanging basket platform, which is installed on the outer side of the main truss through a hanger.

[0008] Preferably, a suspension rod penetrating the hanger is provided at the upper end of the hanging basket platform, and the hanging basket platform is connected to the hanger through a hanging basket lifting cylinder.

[0009] Preferably, the bearing platform of the hanging basket platform is provided with a hanging basket telescopic platform which can be telescoped outward or inward; the telescopic platform is driven by an oil cylinder.

[0010] Preferably, the hanger lifting device comprises a hanger guide rod, a sleeve and a hanger lifting cylinder.

[0011] The guide rod is fixedly installed on the outside of the truss and passes through the sleeve.

[0012] The sleeve is fixedly installed on the inner side of the hanger.

[0013] The front end of the telescopic rod of the hanger lifting cylinder is connected to the sleeve, and the bottom of the cylinder body of the hanger lifting cylinder is connected to the main truss.

[0014] Preferably, the rear end of the sleeve is provided with a buckle wheel matching the main truss column.

[0015] Preferably, the template hoisting mechanism includes a hanger sleeve and a template moving cylinder, the hanger sleeve is sleeved on the cross bar at the lower end of the hanger, the telescopic rod of the template moving cylinder is connected to the hanger sleeve, and the cylinder body is fixedly connected to the hanger; the hanger sleeve is connected to the anti-collision wall template through a connecting device.

[0016] Preferably, the connecting device adopts a basket screw or a hoist.

[0017] Preferably, the walking mechanism includes driving wheels installed in the rear row of the lower end of the load-bearing platform and driven wheels that can be steered and are located in the front row of the lower end of the load-bearing platform; the driven wheels adopt hydraulic steering, and the driving wheels and the driven wheels adopt solid tires, thereby facilitating the movement and steering of the entire trolley.

[0018] A method for constructing an anti-collision wall comprises the following construction steps:

[0019] ① Connect multiple anti-collision wall templates through template connectors (screws or basket bolts, etc.) to form a 10-12 meter long template group;

[0020] ② Use the anti-collision wall construction trolley to hoist the array template group as needed,

[0021] The template hoisting mechanism is used to hoist the array template group, and then the template group is moved to the designated position through the traveling mechanism of the trolley, and the template hoisting mechanism is used to move the anti-collision wall template group to the outside or inside, and after accurate positioning and fixing, the template group is separated from the template hoisting mechanism;

[0022] ③ Pour concrete into the multiple sets of formwork groups positioned in step ② to form a crash barrier;

[0023] ④ After the crash wall in step ③ is solidified and formed, the formwork group is disassembled according to the principle of "cast first and then dismantle", and the dismantled formwork group is hoisted to the position where the crash wall needs to be cast by a trolley, and the formwork group is positioned, assembled, and cast in turn; such a cyclic casting process greatly improves construction efficiency, reduces the labor intensity of operators, and improves casting quality.

[0024] ⑤ Turn the trolley around, modify the cast crash wall, and install bridge ancillary facilities.

[0025] In this construction method, the height of the hanging basket is adjusted by the hanger lifting device of the trolley and the hanging basket lifting cylinder. The hanging basket platform can cross the anti-collision wall or the anti-throwing net installed on the upper end of the anti-collision wall, thereby realizing the construction of the anti-collision wall accessories.

[0026] At the same time, the trolley can turn around to carry out construction of the anti-collision wall on the other side, or the hanging basket can stay at the required elevation to carry out modification of the anti-collision wall.

[0027] The hanging basket is provided with a cylinder for controlling the horizontal extension and retraction of the working platform. The cylinder drives the telescopic platform of the hanging basket to extend under the bridge to install the bridge ancillary facilities.

[0028] The present invention has the following beneficial effects:

[0029] The present invention has reasonable design, simple structure and convenient use. It is an anti-collision wall trolley with a reasonably designed hanger. A template lifting mechanism is arranged on the hanger. The template lifting mechanism can hang the template group through a basket screw or a gourd, and the template group can be moved inward or outward. At the same time, a hanger lifting device is reasonably arranged on the main truss, and the hanger lifting device can drive the hanger to move up and down; and a reasonably designed walking mechanism can well drive the entire trolley to move and turn, thereby making it more convenient to lift the template group and realizing cyclic operation.

[0030] The frame lifting device and the template hoisting mechanism can be driven by a hydraulic cylinder, or by a steel rope and a motor, or by a steel rope and a hydraulic cylinder to improve the safety of movement and the efficiency of movement.

[0031] The counterweight is reasonably designed, which can ensure the stability of the center of gravity of the entire trolley, making it safer and more reliable. At the same time, the counterweight adopts a box-type counterweight, and concrete blocks are placed in the box. Concrete blocks of different weights can be placed according to needs, so that the counterweight is better matched with the entire trolley.

[0032] The hanger rod is reasonably designed so that it can realize the guiding function, and a cross beam is arranged at the upper end of the hanger rod, which can play a role of limiting and preventing the guide rod from moving down too far and falling off the hanger.

[0033] The properly designed vertically and horizontally movable hanging platform can stay at different heights to install and disassemble the anti-collision wall template and modify the anti-collision wall; it can also be extended under the bridge to install bridge ancillary facilities (such as downpipes, etc.). While meeting the construction of the anti-collision wall, the telescopic platform of the hanging platform also reduces the risk of debris falling and plays a safety protection function.

[0034] At the same time, the anti-collision wall construction method also solves the problem of low efficiency of traditional manual splicing of single templates. The method disclosed in the present invention is to hoist and splice the templates in groups, which reduces the number of splicing times in the entire construction process, and reasonably adopts the trolley template for convenience in movement. Since the number of splicing times in the whole process is small, the gap is better controlled; the grouped templates are also efficient in erecting, demoulding and transportation. Compared with traditional methods, this construction method improves efficiency several times. BRIEF DESCRIPTION OF THE DRAWINGS
