Description

Hydraulic self-propelled inclined hole normal concrete pouring trolley

technical field

The invention belongs to the field of engineering machinery manufacturing, in particular to the field of concrete pouring engineering machinery manufacturing, in particular to a concrete pouring trolley for concrete pouring in horizontally inclined tunnels.

Background technique

Concrete pouring is often carried out in the construction of water conservancy and hydropower projects. The usual method is to pour concrete after installing and fixing the formwork separately. With the improvement of engineering quality and speed requirements, the requirements for engineering construction equipment are also constantly increasing. At present, there are tunnel construction trolleys that can use pumped concrete for continuous construction of side and roof arches or normal concrete for side wall construction. There is no equipment that can use normal concrete to pour tunnel side walls and pump to pour concrete at the same time. Especially in the construction of inclined tunnels, the tunnel construction conditions are diverse, and there are often changing slopes and curved tunnels. The construction environment And the conditions are complicated, and there is no normal automatic pouring equipment that can adapt to the various changes of inclined tunnels conveniently, safely and efficiently. Chinese patent 200920304405.9 discloses a tunnel pouring trolley capable of pouring side walls.

Generally, the moving mechanism of the tunnel trolley uses electricity or a motor to directly drive the steel wheels on the track to move. Whether it is electric power or engine drive, it is usually necessary to drive the steel wheel through the transmission device, and the above-mentioned moving mechanism can also be competent when the load is not large, especially in the horizontal moving state.

However, the formwork trolley has a huge weight and often needs to be constructed under complicated conditions. When the construction tunnel is horizontally inclined or curved, the power and engine-driven trolley cannot meet the needs of the tunnel formwork trolley, and the following problems exist: the formwork trolley The movement is only carried out after a section of construction is completed, and there is no need to move at any time; the driving power device needs to be installed on the trolley, which increases the weight of the trolley; in complex construction situations, the drive is often unstable, because the trolley usually needs to be installed with four moving parts When the track is moving, the moving devices are different, and the movement is often uncoordinated, which brings safety hazards to the construction; when the tunnel is constructed in a horizontally inclined state, the heavy trolley does not have a device fixed to the ground foundation, and it is easy to slip back and move. Construction poses safety hazards.

Concrete pouring trolley is mainly composed of steel structure, and its weight is relatively heavy. After the formwork and auxiliary equipment are installed, the weight increases greatly. The safety of pouring trolley is a very important issue, especially when the side wall pouring and top arch pouring are integrated. One piece, the weight increase is very large. If it is constructed in a complex environment, such as inclined tunnels and curved tunnels, the safety of the trolley and even whether it can work normally are issues that must be paid attention to. Safety is first and foremost a mobile and fixed issue.

In summary, the hydraulic self-propelled inclined tunnel normal concrete pouring trolley integrates the normal concrete pouring of the side wall and the pumping concrete for the top arch in tunnel construction at the same time on one trolley; especially in the construction of inclined tunnels, Due to the constant change of the tunnel slope and the complex construction environment and conditions, the side support frame and hydraulic moving mechanism of the present invention are well adapted to the construction needs, and the side support frame securely fixes the entire trolley, ensuring construction safety, and It is easy to install and move, and the hydraulic moving mechanism is safe and reliable when moving the trolley. It is especially suitable for the movement of a trolley with a certain height and weight. It runs stably no matter in a straight line or in a curved section or other complicated areas.
