Description

Supporting equipment carrying device, supporting system and heading machine Technical Field The invention relates to the field of full-face tunneling equipment, in particular to a supporting equipment carrying device, a supporting system and a tunneling machine. Background The full-face heading machine is widely applied to the construction of a tunnel or a footrill which is lined or not lined, and has the advantages of high construction efficiency, good safety, small influence on the surrounding environment in the construction process and the like. In the construction process of the heading machine, the construction position is required to be supported and reinforced frequently, for example, when poor geology and other conditions are met, a supporting system is required to be adopted to support and reinforce surrounding rocks and the like in advance, so that the safety of constructors and the smooth passing of the heading machine are ensured. According to the application division, the support system is generally divided into an anchor rod drilling machine system, an anchor cable drilling machine system, an emergency mixed spraying system, a molding system, an advanced drilling machine and the like. The anchor rod drilling machine system is used for carrying out anchor rod support, the emergency mixed spraying system is used for coping with the situation that surrounding rock of a weak broken stratum cannot be self-stabilized, the injection system is used for coping with the situation that surrounding rock fall cavities influence tunneling of a tunneling machine, and the advanced drilling machine system is used for carrying out advanced geological treatment on the tunneling machine. Since the position to be supported is often a full circle around the heading machine, the support system should have a sufficient working area in the circumferential direction of the heading machine, which is usually 360 ° around the heading machine, in order to meet this requirement, a carrying device is provided on the main beam of the main body of the heading machine, which comprises an annular rail, and a support device trolley movable along the annular rail is provided on the annular rail, by which the support device trolley is driven to work at different positions. In engineering practice, the support system often works at the front position of the main machine of the heading machine and is arranged close to the face. However, because the upper part and the lower part of the tunneling machine are the personnel channels, the material transportation area, the cutter conveying area, the lower slag removing area and the like, particularly when slag is accumulated at the bottom of a tunnel, the tunneling machine is required to be driven into the tunneling machine to remove the slag rapidly, so that the top space and the bottom space of the tunneling machine cannot be occupied. Therefore, in the prior art, the annular track of the support system is generally divided into an upper track section, a lower track section, a left track section and a right track section, and when the 360-degree range support is not used for normal tunneling of the tunneling machine, the upper track section and the lower track section are not installed so as to ensure personnel channels, material transportation channels, a knife conveying space and a lower slag removing space of the upper part and the lower part of the tunneling machine. When the support system is required to be used in the range of 360 degrees, the upper rail section and the lower rail section are manually connected with the left rail section and the right rail section. The manual disassembly and assembly of the upper track section and the lower track section have the problems of high labor intensity, low efficiency and the like, and can bring adverse effects to the follow-up precision and reliability of the track after frequent disassembly. In the patent, the applicant proposes to set an opening on a traveling platform at the upper part of a heading machine, set lifting cylinders between the left and right ends of an upper track section of the track and a main beam respectively, stop the support device on the upper track section when the support operation is not performed, separate the two ends of the upper track section from the left track section and the right track section, enable the lifting cylinders to be in a retracted state, enable the opening on the lifting platform to be covered by a cover plate, and enable the support device to be hidden under the traveling platform for standby. When the support operation is needed, the cover plate is disassembled, the upper track section is jacked up through the lifting oil cylinder, and two ends of the upper track section are butted with the left track section and the right track section by means of manpower. The efficiency of deploying the support system can be improved to a certain extent through the arrangement of the lifting oil cylind
