Problems solved by technology

[0006] According to past experience, multiple sets of trolleys are generally used in the concrete construction of flood discharge tunnels in my country's hydropower projects, and the concrete construction is started at the same time on different working faces. Each lining section is arranged with a lining trolley, the equipment cost is too high, and the trolley is driven by a hoist, which has high potential safety hazards and great safety risks

Embodiment 1

[0037] see Figure 1-2 , a variable-section hydraulic self-propelled trolley, which includes a trolley track 1 fixed on the lining floor, and a plurality of sets of track wheels 6 are installed on the top rolling support of the trolley track 1, and the track wheels 6 are fixedly mounted on the wheel On the support frame 5, a trolley frame 14 is installed on the wheel support frame 5 through a lifting mechanism, and a trolley power unit for trolley movement is installed on the bottom of the trolley frame 14, and the trolley frame The top of 14 is fixedly installed with a plurality of telescopic sleeves 30 across the top, and telescopic rods 29 are mounted on the inside of the telescopic sleeves 30 through sliding fit, and telescopic hydraulic cylinders 31 are installed between the telescopic sleeves 30 and the telescopic rods 29. , the outer end surface of the telescopic hydraulic cylinder 31 is fixedly installed with a template 26 for pouring, and a stripping hydraulic cylinde...

Embodiment 2

[0048] The operation method of any one of the variable-section hydraulic self-propelled trolleys for side wall lining construction includes the following steps:

[0049] Step 1: Support the entire trolley on the trolley track 1 through the track wheels 6;

[0050] Step 2: Adjust the height of the lifting hydraulic cylinder 15 according to the height of the tunnel, and then adjust the height of the trolley frame 14 to adapt to tunnels of different heights;

[0051] Step 3: Adjust the telescopic hydraulic cylinder 31 and the stripping hydraulic cylinder 27 according to the width of the tunnel, and then push the template 26 to move to the side wall to be poured, and then pour it;

[0052] Step 4: After the pouring of the side wall lining of this warehouse surface is completed, the film is removed, the power unit of the trolley is started, and the above-mentioned trolley is driven to move as a whole through the climbing hydraulic cylinder 7, and enters the next warehouse surface; ...

Abstract

The invention provides a variable section hydraulic self-propelled trolley and an operation method thereof. Multiple groups of rail wheels are arranged at the top of a trolley rail in a rolling and supporting way; the rail wheels are fixedly arranged on a wheel supporting frame; a trolley frame is arranged on the wheel supporting frame through a lifting mechanism; a trolley power device for movingthe trolley is arranged at the bottom of the trolley frame; a plurality of telescopic sleeves are fixedly arranged at the top of the trolley frame in a crossing way; telescopic rods are arranged in the telescopic sleeves in a sliding fit way; a telescopic hydraulic cylinder is arranged between the telescopic sleeves and the telescopic rods; a template for pouring is fixedly arranged on the outerend face of the telescopic hydraulic cylinder; and a demolding hydraulic cylinder for demolding is arranged between the template and the trolley frame. The trolley can realize construction of variouslining bodies of cavity concrete, can effectively guarantee the cavity lining construction period and can reduce a large amount of equipment input and labor cost.

Description

technical field [0001] The invention relates to the construction of cavern lining concrete, in particular to a variable-section hydraulic self-propelled trolley and its operating method. Background technique [0002] The flood discharge tunnel project of Baihetan Hydropower Station mainly includes 3 flood discharge tunnels, and each flood discharge tunnel is composed of the entrance gradient section, the upper flat section and the Longluowei section. Longluowei is composed of wauchi curve section, slope section and anti-arc section. The method of the Wauchi curve is Z=X2 / 500+0.015X, the slope section is the transition section between the Wauchi curve and the inverse arc, the slope of the 1# and 2# spillway tunnel slope is 1:4, and the slope slope of the 3# spillway tunnel is 1:3.72. The anti-arc section is located downstream of the slope section, and the anti-arc radius is 300m. The 1# and 2# flood discharge tunnels are directly connected to the nose sill by the reverse ar...
