Problems solved by technology

[0004] 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

Embodiment 1

[0035] figure 1 It is a structural schematic diagram of the trolley of the present invention in the tunnel cross section when the concrete is poured, figure 2 It is a structural schematic diagram of the trolley of the present invention in the cross section of the tunnel when it is in a moving state, image 3 It is a schematic diagram of the side structure of the trolley of the present invention.

[0036] Such as figure 1 , figure 2 , image 3 As shown, the hydraulic self-propelled inclined tunnel normal concrete pouring trolley includes a frame and a side wall pouring mechanism, and also includes a top arch pouring mechanism, and a hydraulic traveling mechanism hinged with the trolley frame and arranged at the bottom of the frame.

[0037] The vehicle frame consists of gantry columns 4, 7, gantry diagonal braces 5, gantry struts 13, gantry vertical braces 15, gantry cross braces 17, gantry beams 19, gantry diagonal stays 21, 22, gantry horizontal Pull bar 23 etc. parts ...

Embodiment 2

[0052] to combine figure 1 , figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 .

[0053] The other mechanisms are the same as in Embodiment 1, but the different structures are: the trolley hydraulic traveling device consists of a traveling track fixed on the track bolster, a traveling mechanism moving on the traveling track, the traveling mechanism is hinged to the bottom beam of the trolley frame, and the other end Hinged with the hydraulic cylinder, the hydraulic cylinder is connected with the locking mechanism, the locking mechanism can be fixed on the track bolster and detachable, and the hydraulic cylinder provides the moving power of the trolley.

[0054] As shown in the figure, the moving track includes track b1, track bolster b2, and track foundation. Track b1 is first fixed on track bolster b2 by conventional methods. There is a track fixing buckle at the front joint of b2, and the track fixing buckle and track b1 are welded and fixed tog...

Abstract

The invention discloses a hydraulic self-running inclined-hole ordinary-state concrete casting trolley which comprises a trolley frame, a sidewall casting mechanism, a top arch casting mechanism and a hydraulic running gear, wherein the hydraulic running gear is hinged with the trolley frame and arranged on the bottom of the trolley frame; and the hydraulic running gear comprises a running mechanism, a hydraulic ram capable of moving the trolley, and a locking mechanism capable of fixing the trolley. The invention can be used for simultaneously casting tunnel sidewalls with concrete in ordinary state, and pumping and casting the top arch; the trolley can move conveniently; the hydraulic running gear can move in a stable and reliable way; the trolley is especially suitable for complex tunnel construction conditions; and the locking mechanism is fixed on the rail corbels on the ground, thereby realizing safe and reliable operation of the integral trolley and also fixing the trolley in the casting process.

Description

technical field [0001] 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 [0002] 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 construct...
