Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, and more specifically, to a self-tilting side wall formwork trolley, a device and a use method thereof. Background Art

[0002] During the excavation of large-section open-cut tunnels, due to the large number of cross-sectional forms of the tunnel's main structure, the side walls, partition walls and roof need to be cast in batches. Therefore, conventional full-section trolleys are difficult to use, especially for the side wall casting, which requires the selection of a suitable template trolley based on the actual situation of the tunnel construction.

[0003] At present, the existing technologies are divided into two types: 1. Commonly used construction methods, including scaffold formwork method and steel formwork plus triangular support. The scaffold formwork method mainly uses a full-floor steel pipe scaffold to build a support system, uses square wood as the formwork keel, and uses plywood as the formwork support on the outside. Its disadvantages are that there are many joints, and the disassembly and assembly of the scaffold and the demoulding process of the cylinder are cumbersome and labor-intensive. For the demoulding of steel formwork plus triangular support, a large crane is required to place the formwork, which is affected by the foundation pit support system and is difficult to position. 2. The side wall formwork trolley adds a scaffold system and walking equipment on the basis of the steel formwork, and uses multiple cylinders to adjust and demould between the formwork and the side wall. Its disadvantages are that it has high requirements for the synchronization of the cylinders, and the demoulding operation requires certain technical requirements. Summary of the invention

[0004] In view of the problem of demoulding difficulty in the prior art, the purpose of the present invention is to provide a self-tilting side wall formwork trolley to improve the demoulding efficiency and solve the problems of time-consuming and labor-intensive disassembly and movement of the side wall formwork during the demoulding process.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A self-tilting side wall formwork trolley comprises a frame, a template is adjustably arranged on one side of the frame, an adjusting device for adjusting the position of the template is arranged between the template and the frame, a wheel running device for facilitating the movement of the frame is arranged at the bottom of the frame, and a self-tilting demoulding device for pushing the frame to tilt is also arranged at the bottom of the frame;

[0007] The self-tilting demoulding device comprises a rotating mechanism and a pushing device which are respectively arranged on both sides of the frame.

[0008] Through the above technical solution, the wheel walking device is used to reduce the labor of workers in the process of moving the template; when in use, the pushing device lifts the frame, drives the frame to tilt, adjusts the template to the required casting position, and after the cast material is formed, a unique demoulding method is adopted: the pushing device is retracted, and then under the action of the template trolley, it rotates with the rotating mechanism as the axis, drives the template to move and complete demoulding, simplifies the demoulding method, and effectively reduces the demand for operating technology.

[0009] Further, the adjustment device includes a coarse adjustment device and a fine adjustment device;

[0010] The coarse adjustment device comprises a telescopic cylinder fixed on the frame and used for driving the template to move.

[0011] Through the above technical solution, the adjustment device adopts a telescopic cylinder to reduce the lateral length of the self-tilting side wall formwork trolley and save the space required for construction.

[0012] Furthermore, one end of the telescopic oil cylinder is hinged to the frame, and the other end is hinged to the template. A sleeve is fixed on the frame, and the telescopic oil cylinder is inserted into the sleeve.

[0013] Through the above technical solution, the telescopic oil cylinder drives the connection between it and the template to move, and the position of the template is roughly adjusted.

[0014] Furthermore, the fine adjustment device includes a plurality of telescopic screws, and two ends of the telescopic screws are respectively connected to the template and the frame.

[0015] Through the above technical solution, the telescopic screw is used to further adjust the inclination angle position of the template.

[0016] Furthermore, the rotating mechanism is a ball joint, and the pushing device is a supporting cylinder.

[0017] Through the above technical solution, the ball joint is used to facilitate the tilting of the frame, and the supporting cylinder pushes the frame to tilt, which is convenient for subsequent demoulding by self-weight.

[0018] Furthermore, the wheel travel device includes a steel rail laid on the bottom of the frame, and the bottom of the frame is rotatably connected to a roller that cooperates with the steel rail.

[0019] Through the above technical solution, the sliding cooperation between the roller and the rail is adopted to reduce the labor of workers in the process of moving the template.

[0020] Furthermore, a counterweight block is provided on one side of the frame close to the pushing device.

[0021] Through the above technical solution, loading the self-weight counterweight block can not only prevent the frame from tipping over, but also facilitate the automatic separation of the formwork and the casting wall, further simplify the demoulding method, and effectively reduce the demand for operating technology.

[0022] A self-tilting side wall formwork trolley device comprises a plurality of the above-mentioned self-tilting side wall formwork trolleys, wherein adjacent frames are detachably connected with hinge connection modules for driving the plurality of frames to move simultaneously.

[0023] Through the above technical solution, a hinge connection module is adopted to facilitate the simultaneous movement of multiple frames and increase the casting length.

[0024] Furthermore, the frame is provided with connecting columns, and connecting screws for connecting adjacent frames are provided between the connecting columns on adjacent frames.

[0025] Through the above technical solution, the connecting screw is connected to the adjacent frames, so that the adjacent templates can be demoulded at the same time.

[0026] A method for using a self-tilting side wall formwork trolley device, based on the above-mentioned self-tilting side wall formwork trolley device, comprises the following steps:

[0027] Step 1, preparation before pouring: move the self-tilting side wall formwork trolley to the designated position through the hoisting equipment, lift up the self-tilting side wall formwork trolley, install the self-tilting demoulding device at the bottom of the frame, change the position of the formwork through the adjusting device, and control the pouring thickness;

[0028] Step 2, demoulding process: place a counterweight on the frame, remove the hinge connection modules between two adjacent sets of self-tilting side wall formwork platforms, retract the jacking device, and use the deadweight of the formwork trolley to separate the casting wall and the formwork;

[0029] Step three, finish demoulding: after demoulding is completed, lift up the self-tilting side wall formwork trolley, remove the self-tilting demoulding device, move the self-tilting side wall formwork trolley to the next position and repeat the operation.

[0030] Through the above technical solution, a unique demoulding method is adopted: the pushing device is retracted, and then under the action of the template trolley, the rotating mechanism is used as the rotating axis to drive the template to move and complete the demoulding, which simplifies the demoulding method and effectively reduces the demand for operating technology; the trolley units are assembled and demoulded in groups to prevent the bending damage that may be caused by the self-tilting demoulding process of the template, which is convenient for control.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) A unique demoulding method is adopted: the push-pushing device is retracted, and then the template trolley rotates with the rotating mechanism as the axis, driving the template to move and complete demoulding, simplifying the demoulding method and effectively reducing the demand for operating technology;

[0033] (2) Furthermore, by connecting the lead screw and the hinge connection module, not only can the one-time demoulding distance be ensured to be long enough, but also the distance between the templates can be shortened, thus preventing the templates from being twisted and deformed during the demoulding process, thereby improving work efficiency;

[0034] (3) Furthermore, by setting the adjustment device as a telescopic structure, the lateral length is reduced, the lateral space of the trolley is saved, and it can pass through a narrow space and ensure the accuracy of the cast wall. BRIEF DESCRIPTION OF THE DRAWINGS
