Description

Technical Field

[0001] The utility model belongs to the technical field of gob-side tunnel retaining support equipment in coal mines, and in particular relates to a formwork hanging device base. Background Art

[0002] The technology of retaining lanes along the goaf is currently widely promoted and applied in domestic underground mines. With the continuous development of the technology of retaining lanes along the goaf, related equipment has also been continuously developed, further improving the applicability, mechanization and even automation of the technology, greatly reducing the intensity of manual labor, improving construction efficiency, and ensuring the safety of operators. The flexible formwork concrete technology of retaining lanes along the goaf is widely used in the technology of retaining lanes along the goaf in China because of its good applicability and the continuous optimization and improvement of related supporting equipment.

[0003] The applicant applied for a utility model patent named "Mechanized Formwork Hanging Device" in 2022, with patent number 202220215516.8. The formwork hanging device has been used in many mines, which has improved the efficiency of flexible formwork hanging, reduced the number of operators, and improved the technical equipment level of flexible formwork along the goaf. The goaf-side goaf-retaining formwork hanging device has the functions of flexible formwork hanging, roof support, self-movement, and deviation correction. The formwork hanging device has been used in many mines, reducing the number of operators and improving construction efficiency and mechanization. However, there are also some problems. Since the formwork hanging device is an internal and external frame structure, considering that its width in the tunnel cannot be too large, otherwise it will affect other equipment, the base of the internal and external frames is narrow. At the same time, when the coal seam has an inclination and the bottom plate is soft, it is easy to tilt and drill the bottom, affecting its frame movement and the verticality of the wall. During the wall pouring operation and maintenance, personnel need to use portable escalators to go up and down, which is inconvenient to operate. After the pouring is completed, the demoulding is carried out by telescoping the tensioning jacks between the inner and outer frames. When the formwork hanging device is long and the bottom plate is soft, there are problems such as difficulty in demoulding. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0019] Example 1

A guardrail 6 is arranged on the periphery of the safety platform 5, and a ladder 4 is connected to the lower side of the safety platform 5.

[0021] During gob-side tunneling operations, when the coal seam has an inclination or the bottom plate is soft and the formwork device is tilted, the side thrust mechanism 2 can be operated to give a side thrust to the formwork device to straighten it.

[0022] During demoulding operation, the demoulding mechanism 3 can be operated to give a lateral thrust to the flexible mold wall. Since the flexible mold wall has a large deadweight, the mold hanging device is separated from the flexible mold wall under the action of the reaction force to achieve demoulding.

[0023] During the pouring operation and maintenance operation, the personnel can go up to the safety platform 5 through the ladder 4 to carry out construction work. There are guardrails 6 on both sides of the safety platform 5 to ensure the safety of the operators.

[0034] The base of the bottom push jack 302 is connected to the second fixed cylinder 301 through a pin shaft. When the demoulding mechanism 3 supports the flexible mold wall, the bottom push jack 302 will extend from the second fixed cylinder 301. During the demoulding operation, the bottom push jack 302 can be operated to give a lateral thrust to the flexible mold wall to separate the wall and the hanging mold device.
