Description

Technical Field

[0001] The utility model belongs to the field of coal mine non-coal pillar mining technology equipment, and specifically relates to a bottom lifting mechanism of a hanging mold device. Background Art

[0002] The technology of retaining lanes along the goaf is currently being 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 technology of retaining lanes along the goaf of flexible formwork concrete has been promoted and applied in many mining areas across the country. In order to solve the problem of hanging flexible formwork for flexible formwork concrete retaining lanes along the goaf, the applicant applied for a utility model patent named "Mechanized Formwork Hanging Device" in 2022, with patent number 202220215516.8. The hanging formwork device has been used in many mines, which has improved the efficiency of hanging flexible formwork, reduced the number of operators, and improved the technical equipment level of flexible formwork retaining lanes along the goaf. The hanging formwork device for retaining lanes along the goaf is generally arranged in the lane and has functions such as hanging flexible formwork, roof support, self-movement, and deviation correction. The formwork hanging device has been applied in many mines, reducing the number of operators and improving construction efficiency and mechanization. However, there are also some problems. When the bottom plate is soft, the bottom drilling phenomenon is inevitable, which affects the self-movement of the device. Although the bottom lifting device is commonly used in hydraulic supports on the working surface, an inverted jack is generally used as the bottom lifting mechanism. When the support needs to be lifted, the jack piston rod is extended to contact the bottom plate, and the support base is lifted under the reaction force. However, when the bottom plate is relatively weak, there is also the problem that the bottom lifting jack is easy to drill the bottom. 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.

[0015] 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.

[0018] The bottom lifting shoe 5 is hinged on the box body 1 of the mold hanging device, the fixed cylinder 2 and the auxiliary pulling device 3 are arranged on the box body 1 of the mold hanging device, the reciprocating drive mechanism 4 is arranged in the fixed cylinder 2, and the driving end of the reciprocating drive mechanism 4 is in surface contact with the bottom lifting shoe 5.

[0019] When the formwork device moves forward, the reciprocating drive mechanism 4 is first driven to contact the bottom lifting shoe 5. Because the bottom lifting shoe has a large surface area and a small relative pressure to the ground, the box body 1 of the formwork device is lifted off the bottom plate under the action of the reaction force, thereby preventing the bottom of the box body 1 from drilling into the bottom. The formwork device can move forward under the action of its own pushing mechanism; after the formwork device moves to an appropriate position, the reciprocating drive mechanism 4 is retracted, and the box body 1 of the formwork device contacts the bottom plate of the tunnel, and the formwork work begins. This reciprocating process is repeated to realize the forward movement of the formwork device until the tunnel soft formwork wall casting is completed.

[0020] Therefore, compared with the existing devices, the bottom lifting mechanism of the mold hanging device of the utility model has the following advantages: (1) The bottom lifting mechanism of the mold hanging device of the utility model is provided with an enlarged and widened bottom lifting shoe under the bottom lifting jack, and the bottom lifting shoe is movably connected to the base of the mold hanging device. The bottom lifting jack contacts the bottom shoe surface to increase the contact area, reduce the specific pressure, and effectively solve the problem of the mold hanging bracket drilling the bottom in a weak bottom plate environment. (2) The bottom lifting mechanism of the mold hanging device of the utility model is connected to the box base by a pin shaft, and the bottom adopts a bottom lifting shoe. The bottom lifting shoe is movably connected to the box base of the mold hanging device, which has a simple structure and is easy to install and disassemble; (3) The bottom lifting mechanism of the mold hanging device of the utility model can adjust the lifting height of the bottom lifting shoe according to the undulation of the bottom plate of the tunnel, and determine the stroke in the up and down direction according to the lifting height, thereby determining the hinge position of the bottom lifting shoe and the box of the mold hanging device.
