Description

[0002] With the rapid development of domestic infrastructure construction field, the quantity of vertical shaft engineering is increasing, and the vertical shaft heading machine is usually composed of main machine and hanging plate, in the actual application process of vertical shaft heading machine, due to the large number of equipment arranged on the hanging plate and the different types, it is difficult to realize the complete balanced distribution of the weight of the equipment on the hanging plate layer. This unbalanced distribution can cause the partial weight of the hanging plate part, and further cause the deflection of the hanging plate in the lowering process. At the same time, since the hanging plate is suspended by winch lifting equipment (such as steel wire rope), it will inevitably swing freely in the lowering process.

[0003] At present, in view of the deflection and swing problems in the lowering process of the hanging plate of the vertical shaft heading machine, the following two methods are mainly used to solve them: one is to balance the arrangement of various equipment on the hanging plate layer as much as possible to reduce the trend of partial weight and deflection; the second is to lower the hanging plate very slowly by using multiple winch lifting equipment, and when the hanging plate is deflected, the posture of the hanging plate is adjusted by the winch lifting equipment in the corresponding direction. However, both methods have obvious limitations. The first method cannot completely realize the load balance of the equipment on the hanging plate layer, and the partial weight and deflection problems still exist; the second method is time-consuming and labor-intensive, and the operator needs to observe and adjust frequently, which seriously affects the operation efficiency of the vertical shaft heading machine.

[0004] Therefore, it is a technical problem to be solved by the technical personnel in the field to develop a new technical device that can effectively solve the deflection and swing problems in the lowering process of the hanging plate of the vertical shaft heading machine, so as to improve the stability and operation efficiency of the vertical shaft heading machine.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a vertical tunneling machine platform stabilization device is provided, which mainly includes a fixed arm 1 and a telescopic arm 2.

[0021] In this embodiment, the fixed arm 1 adopts a box-shaped steel structure design with a hollow interior forming a sliding guide rail. The telescopic arm 2 also adopts a box-shaped steel structure and is nested inside the fixed arm 1, allowing it to extend and retract along the sliding guide rail of the fixed arm 1.

[0022] A connecting seat 31 is welded to the front end of the telescopic arm 2, serving as part of the roller support 3. Two roller seats 32 are vertically arranged on both sides of the connecting seat 31 for mounting rollers 4. In this embodiment, three rollers 4 are connected to the two roller seats 32 by a central roller and rolling bearings, ensuring that the rollers 4 can rotate flexibly and form effective support with the shaft wall.

[0023] Two hydraulic cylinders 5 are arranged parallel to each other on both sides of the fixed arm 1 to drive the telescopic arm 2 to extend and retract. The rear end of the hydraulic cylinder 5 is connected to the lug 7 fixed to the outside of the fixed arm 1, and the front piston rod is connected to the roller support 3.

[0024] The lower end of the fixed arm 1 is equipped with four flange bases 6, which are used to fix the plate stabilizing device to the hoisting plate of the shaft tunneling machine by bolt connection.

[0025] In use, the stabilizing device of this invention is installed at an appropriate position on the hoisting platform of the shaft boring machine via the flange base 6. Multiple positions can be selected for installation according to construction needs. During shaft boring, when the hoisting platform tilts or sways, the operator can control the piston rod of the hydraulic cylinder 5 in the corresponding position to extend or retract, driving the telescopic arm 2 to slide along the sliding guide rail of the fixed arm 1, thereby adjusting the supporting force between the roller 4 and the shaft wall.

[0026] Roller 4 is made of polyurethane, which has good wear resistance and elasticity, and can tighten the shaft wall in real time, effectively eliminating the tilt and sway of the hoisting platform. Meanwhile, because the supporting force and stroke of the hydraulic cylinder 5 are adjustable, this device can adapt to shaft walls of different diameters and changes in shaft tilt, ensuring the hoisting platform remains stable at all times. Operators can flexibly operate the corresponding stabilizing device to correct the tilt of the hoisting platform according to its specific tilt condition, improving construction safety and work efficiency.
