Abstract
The utility model relates to the field of vehicle-mounted temporary supporting of a heading machine, in particular to a head board automatically adapting to the shape of a roadway roof for a temporary supporting machine, which solves the problem of poor popularity and suitability of a rigid head board of the temporary supporting machine to an arc-shaped roadway roof. The head board is provided with an elastic steel plate, a support spring component and a bottom support frame, wherein one end of the steel plate is hinged with the bottom support frame, and the other end of the steel plate is connected with the bottom support frame in a floating way; and one end of the support spring component is connected with the bottom support frame, and the other end of the support spring component is connected with and supports a spring steel plate. A flexible head board suitable for the arc-shaped roadway is designed, and the shape of the spring steel plate which is contacted with a roadway can be automatically adjusted according to the shape of the roadway, so that the spring steel can be better contacted with the roadway top board, the head board can adapt to arc-shaped roadways with various cross sections, the adaptability of the temporary supporting machine is improved, and the head board is suitable for a vehicle-mounted temporary supporting machine of a suspension heading machine.
Description
Technical field
The utility model relates to the airborne temporary lining of development machine field, and the temporary support machine that is specially a kind of automatic adaptation back shape protects top board.
Background technology
The existing airborne temporary support machine of development machine can alleviate working strength of workers preferably, improves drivage efficiency, protects top board for a kind of plane of rectangle and trapezoidal laneway temporary support machine and just can adapt to, and can well contact with back.But for arched tunnel, on the one hand, because the shape difference of the arch in different tunnels, so the rigidity arch is protected top board and will be complementary with the arch top board and just need customized production; On the other hand, even protecting the arch top board in top board and tunnel, the rigidity of temporary support machine can mate fully in theory, but because the deviation of temporary support machine Support Position, causing and in fact protecting top board mostly just is that several points contact with back, thereby actual supporting effect is not good.
The utility model content
The purpose of this utility model is to provide a kind of temporary support machine of automatic adaptation back shape to protect top board, and the rigidity that solves temporary support machine is protected top board to the versatility of arched tunnel top board and the problem of bad adaptability.
The technical solution adopted in the utility model is:
A kind of temporary support machine of automatic adaptation back shape protects top board, and this protects top board and is provided with steel spring plate, support spring assembly, end bracing frame, and an end and the end bracing frame of steel spring plate are hinged, and the other end floats with end bracing frame and is connected; One end of support spring assembly is connected with end bracing frame, and the other end is connected with steel spring plate and steel spring plate is constituted support.
The temporary support machine of described automatic adaptation back shape protects top board, and this protects top board and is installed on the temporary support machine, as the workpiece of temporary support machine.
The temporary support machine of described automatic adaptation back shape protects top board, and temporary support machine is the airborne temporary support machine of boom-type roadheader.
Advantage of the present utility model:
1, the utility model flexibility of designing a kind of novel suitable arched tunnel is protected top board, can be according to the shape of the automatic adjustment of the shape in tunnel with the contacted steel spring plate in tunnel, can better contact like this with back, and can make and protect the arched tunnel that top board adapts to multiple section, improve the compliance of temporary support machine.
2, the utility model is applicable to the airborne temporary support machine of development machine airborne temporary support machine, especially boom-type roadheader.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is installed on the schematic diagram of temporary support machine for the utility model.
Among the figure, 1 steel spring plate; 2 support spring assemblies; 3 end bracing frames; 4 protect top board; 5 temporary support machines; 6 development machines.
The specific embodiment
As shown in Figure 1, the utility model temporary support machine protects top board and mainly comprises: steel spring plate 1, support spring assembly 2, end bracing frame 3, and an end and the end bracing frame 3 of steel spring plate 1 are hinged, and the other end floats with end bracing frame 3 and is connected; One end of support spring assembly 2 is connected with end bracing frame 3, and the other end is connected with steel spring plate 1 and steel spring plate 1 is constituted support.
As shown in Figure 2, the utility model is protected top board 4 be installed on the temporary support machine 5, protect the workpiece of top board 4 as temporary support machine 5, temporary support machine 5 is installed on the development machine 6.In the present embodiment, temporary support machine 5 is the airborne temporary support machine of boom-type roadheader.
After development machine 6 is finished headwork, temporary support machine 5 is started working, the hoist cylinder promotion retracting cylinder drive of temporary support machine 5 is protected top board 4 and is moved upward, after protecting top board 4 and the arch top board contacting, compression support spring assembly 2, steel spring plate 1 compresses top board formation setting load according to the warpage of arch top board simultaneously.
