Description

Technical Field

[0001] This utility model relates to the field of coal mine measurement technology, and in particular to a measuring basket device for coal mine TBM construction. Background Technology

[0002] In the construction of a TBM (Total Station Machine) in an inclined shaft of a coal mine, a total station basket for a measurement and guidance system needs to be installed at the right shoulder of the roadway. When setting up the total station basket, the anchor bolt positions are first determined based on the hole dimensions of the steel plate base. After positioning, three 1m long anchor bolts are driven in, and the anchor bolts are connected to the steel plate base via threaded rods at the bottom for leveling. The following defects exist:

[0003] Low construction efficiency: Anchor bolt installation relies on manual operation, requiring 3 people to cooperate for a single installation, which takes about 2 hours;

[0004] Precision control is difficult: the anchor bolt angle is prone to deviation, and leveling the suspended platform is difficult, which affects the measurement accuracy;

[0005] High cost: It requires the consumption of anchor bolts and anchoring agents, resulting in high material costs.

[0006] There is a lack of dedicated devices in the current technology that can be quickly disassembled and dynamically adjusted, which urgently needs to be improved. Utility Model Content

[0007] To address the problems of low installation efficiency, reliance on manual operation, and material waste in existing total station suspended platform technologies, this utility model provides a modular, adjustable suspended platform device that enables rapid installation, reuse, and high-precision leveling.

[0008] The technical solution provided by this utility model:

[0009] A surveying basket device for TBM construction in coal mines includes an angle iron gate frame and a channel steel platform, wherein the upper part of the angle iron gate frame is fixed to the roadway;

[0010] The channel steel platform is connected to the angle iron gate frame via an adjustable connecting mechanism;

[0011] The adjustable connection mechanism includes multiple sets of bolt holes for supporting angle adjustment and horizontal calibration;

[0012] The angle iron gate frame is detachably connected to the channel steel platform through multiple sets of bolt holes.

[0013] Furthermore, the angle iron gate is supported by two brackets, one long and one short.

[0014] Furthermore, the upper part of the angle iron gate frame is provided with an integrally formed lifting lug.

[0015] Furthermore, the lug has a U-shaped structure and an anti-slip rubber pad is provided on the inner side.

[0016] Furthermore, the lifting lug is connected to the existing anchor bolt in the roadway via an M36 nut.

[0017] Furthermore, the angle iron gate frame is a gate-shaped frame welded from angle iron.

[0018] Furthermore, the channel steel platform has a mounting hole at its center for easy connection with a total station.

[0019] Furthermore, the mounting hole is circular and connects to the total station via a screw. Furthermore, the adjustable connection mechanism includes a spirit level and fine-tuning bolts.

[0020] The spirit level is installed at the top of the channel steel platform;

[0021] The top of the angle iron gate frame is hollowed out and connected to multiple sets of bolt holes through fine-tuning bolts;

[0022] The bolt hole spacing of the multiple bolt hole positions is 50mm, and the adjustment angle is ±15°.

[0023] Furthermore, reinforcing ribs are welded to the bottom of the channel steel platform. Beneficial effects

[0024] Efficient installation: It uses existing anchor bolts for fixing, without the need to add new anchor bolts, and can be installed by a single person within 15 minutes;

[0025] Precise leveling: Multi-level hole adjustment combined with spirit level calibration enables rapid and precise leveling of the total station;

[0026] Low-cost reuse: The device can be disassembled into standard modules, achieving a 100% reuse rate; Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0031] A measuring basket device for TBM construction in coal mines includes an angle iron gate frame 1 and a channel steel platform 2. An integrally formed lifting lug 3 is provided on the upper part of the angle iron gate frame 1. The lifting lug 3 on the angle iron gate frame 1 is then fitted into the existing anchor rod in the roadway, and the M36 nut is tightened to fix the device in the roadway.

[0032] The channel steel platform 2 is connected to the angle iron gate frame 1 through an adjustable connection mechanism. The total station is connected to the channel steel platform 2 through the mounting holes 4 using screws. Angle adjustment and fine adjustment are achieved through the adjustable connection mechanism, which includes multiple sets of bolt holes 5 for supporting angle adjustment and level calibration. At this time, the angle iron gate frame 1 is detachably connected to the channel steel platform 2 through multiple sets of bolt holes 5, which facilitates assembly and disassembly.

[0033] It should be noted that the measuring device is installed in the right shoulder of the tunnel (for ease of installation, there are two angle iron gate frames, one long and one short). There are obstacles such as ventilation ducts on the top and left side of the tunnel, and the right shoulder is the best measuring channel.

[0034] like Figure 1 As shown:

[0035] To facilitate connection, the lifting lug 3 has a U-shaped structure and an anti-slip rubber pad on its inner side for stable installation.

[0036] like Figure 1 , 3 As shown:

[0037] Among them, angle iron gate frame 1 is a gate-shaped frame made of angle iron welded together.

[0038] like Figure 1 As shown:

[0039] To facilitate connection with the total station, a mounting hole 4 is provided in the center of the channel steel platform 2, and the two are connected by a screw, which also facilitates disassembly and assembly.

[0040] like Figure 1 As shown:

[0041] The adjustable connection mechanism includes a level and a fine-adjustment bolt. The level is installed on the top of the channel steel platform 2 and adjusted to a horizontal state by the fine-adjustment bolt.

[0042] In order to achieve the angle adjustment of the angle iron gate frame 1, its top is hollowed out and connected to multiple sets of bolt holes 5 through fine adjustment bolts. In order to achieve a detachable connection, the bolt hole spacing of the multiple sets of bolt holes 5 is set to 50mm, and the adjustment angle is ±15°. In specific operation, the channel steel platform 2 and the multiple sets of bolt holes 5 of the gate frame 1 are selected according to the slope of the tunnel, and fine adjustment bolts are inserted for pre-fixing.

[0043] like Figure 1-3 As shown:

[0044] To ensure load-bearing stability, reinforcing ribs are welded to the bottom of the channel steel platform 2.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
