Description

Technical Field

[0001] The utility model relates to the technical field of underground equipment transportation in coal mines, in particular to a unit support transportation device for a machine lane. Background Art

[0002] Unit hydraulic support (referred to as unit support) is particularly suitable for advance support and gob-side lane support in underground coal mining working faces due to its simple and reliable structure, compact size, light weight, and flexible use. It has been widely promoted and used in major coal mining enterprises across the country, and has replaced traditional single pillars to become a more efficient and safe hydraulic support product. The conventional transportation methods of unit supports are mainly rail flatbed trucks with small winches or monorail cranes. These two methods can only achieve basic transportation of unit supports, but still have the disadvantages of complex use conditions, high cost, low transportation efficiency, more manpower and time consumption, and high labor intensity. In addition, the flatbed truck equipped with a winch needs to arrange the track in advance, and the monorail crane transportation requires good roof conditions and the ability to hang monorail crane equipment. The applicable conditions are relatively high, and it is not flexible enough when used underground in coal mines, and the efficiency is also low.

[0003] For example, the Chinese invention patent document with publication number CN112390195B discloses a fork-mounted unit support transporter for mining, including a frame platform, a support leg mechanism installed at the front end of the frame platform and a crawler-type walking drive mechanism installed under the frame platform. A gantry mechanism, a cab, a power box and a counterweight device are installed on the frame platform from front to back. A fork-mounted mechanism is installed on the gantry mechanism. A variable-length oil cylinder capable of controlling the gantry mechanism to tilt forward or backward is connected between the gantry mechanism and the frame platform. A support leg oil cylinder for driving the support leg mechanism to extend out and touch the ground for support is connected to the outer side of the gantry mechanism. The above fork-mounted unit support transporter for mining adopts a crawler-type walking drive mechanism, which can adapt to complex road conditions underground. The fork-mounted mechanism is flexible in handling, has strong capacity, and reduces the labor intensity of employees. degree; however, the following problems still need to be overcome: 1. Difficulty in maintenance: the fork-mounted mechanism has a complex structure, and maintenance and repair are difficult and costly; 2. Poor stability and safety during transportation: the support leg mechanism only supports the ground at the front end of the frame platform, and the stability is poor. The unit bracket and fork-mounted mechanism are located at the front end of the frame platform, and a large counterweight needs to be set at the rear of the frame platform to ensure the stability of the vehicle body; 3. High energy consumption of the equipment: the fork-mounted mechanism always remains in a suspended working state during transportation, and the equipment consumes a lot of energy; 4. Poor passability: when transporting the unit bracket, the front fork-mounted mechanism needs to lift the unit bracket to a certain height, and it is more difficult to pass when the coal mine tunnel is low; 5. Exhaust pollution: the transporter uses a diesel internal combustion engine as the power source, and exhaust emissions are inevitable, which pollutes the fresh air flow underground and affects ventilation.
