Embodiment 1

[0023] Embodiment 1: as figure 1 and Figure 4 As shown, a stable support device for a shaft boring machine, the stable support device is installed around the main drive 6 above the cutter head, and the cutter head 7 will inevitably vibrate during the rock excavation process under the action of the main drive, the stable support device is In order to stabilize the cutterhead 7, reduce the impact of equipment vibration on the stratum, improve the safety of the roadheader during the excavation process and the service life of the equipment, a fixed center ring 1 is arranged around the main drive above the roadheader cutterhead, and the fixed center ring 1 There are several telescopic devices on the upper outer ring, and eight sets of telescopic devices are arranged on the upper ring of the fixed center ring. The adjacent telescopic devices are connected by connecting devices. The device is provided with a supporting device, and the telescopic device is connected with the support...

Embodiment 2

[0027] Embodiment 2: as figure 2 As shown, a stable support device for a shaft boring machine, the main panel is provided with a wear-resistant metal strip 401 and a cutting edge guide block 402, and the wear-resistant metal strip 401 is vertically spaced apart, which is beneficial to resist the backlash of the equipment. Torque, the lower part of the main panel is provided with an edge guide plate 402, the edge guide plate 402 is a guide plate with a tip, the edge guide block 402 is detachably connected with the main panel, and the edge guide block 402 is connected to the main panel through high-strength bolts In connection with each other, wear-resistant metal strips 401 are used to increase the friction between the sliding shield 4 and the formation to improve the stability of the support device, and using the edge guide block 402 is more conducive to the sliding shield 4 moving downward along the well wall.

[0028] All the other structures are the same as in Example 1. ...

Embodiment 3

[0029] Example 3, such as figure 1 As shown, a stable support device for a shaft boring machine, the fixed central ring 1 includes several block structures, the fixed central ring 1 is composed of 4 block structures, and the block structures adopt steel structures, and each block structure passes through Bolts are connected, two sets of tensioning cylinders 5 and a set of telescopic sliding boxes 2 are fixed on each block structure, and the two sets of tensioning cylinders 5 and one set of telescopic sliding boxes 2 are connected with a set of sliding shields The inter-connection is convenient, and it is convenient to disassemble the machine underground.

[0030] All the other structures are the same as in Example 1.

Abstract

The invention provides a stable support device of a vertical shaft heading machine. A fixed center ring is arranged above a cutter head of the heading machine, multiple telescopic devices are annularly arranged on the fixed center ring, the adjacent telescopic devices are connected through connecting devices, and supporting devices are arranged on the telescopic devices. The stable support deviceis compact in structural design, the stability of a stratum during heading of the heading machine is guaranteed greatly, influences of equipment vibration on the stratum are reduced, the safety is improved and the service life of equipment is prolonged during heading of the heading machine, meanwhile, equipment reactive torque is provided to prevent the equipment from rotating under cutting torque, and the stable support device can further temporarily support an unstable stratum and earns time for adoption of other auxiliary construction procedures.

Description

technical field [0001] The invention relates to the technical field of shaft construction equipment, in particular to a stable support device for a shaft boring machine. Background technique [0002] With the rapid development of the infrastructure industry, there are more and more shaft construction projects, and various types of shaft boring machines are being continuously developed. The stable support device is an indispensable part of the shaft boring machine. Due to the changeable strata of the shaft, during the excavation process of the existing shaft equipment, vibration will inevitably be generated during the excavation and cutting process of the cutterhead rotation, which will affect the stability of the stratum, the reliability and service life of the equipment. In order to reduce the various impacts produced by the vibration of the cutter head, it is particularly important to develop a stable support device for shaft excavation. Contents of the invention [000...
