Description

Technical Field

[0001] This utility model relates to the field of hydraulic support auxiliary replacement technology, and in particular to a hydraulic support replacement device. Background Technology

[0002] With the development of mechanized coal mining, hydraulic supports need to be installed in the longwall face to ensure the safety of the mining path and personnel. As the advantages of large equipment such as hydraulic supports in mine support and production become increasingly prominent, their application is becoming more widespread, and their transportation is becoming more frequent. Because hydraulic supports are large and heavy, these large pieces of equipment need to be disassembled into components on the surface, for example, the front and rear beams of the hydraulic support need to be separated. Therefore, they need to be transported into the mine using specialized transport vehicles and transported separately to the bottom of the mine for assembly in the mine yard.

[0003] Currently, hydraulic supports in modern fully mechanized mining faces in China are widely transported via rail. The hydraulic supports are placed on flatbed trolleys on rails, transported along the rails to the bottom of the mine, and then transferred to trackless rubber-tired vehicles for delivery to the working face. However, this approach presents another problem: these components are extremely heavy; for example, a single front or rear beam weighs approximately 2.5 tons, making manual assembly extremely inconvenient. Therefore, a dedicated system is urgently needed to address these issues. Existing self-manufactured replacement plates can be used for hydraulic support replacement at the working face, but they are structurally unstable, prone to deformation and damage, unsuitable for long-term use, inconvenient for on-site operations, and prone to support splintering. Utility Model Content

[0004] In order to overcome the defects of existing technology, such as unstable replacement plate structure, easy deformation and damage, inconvenience for long-term use, disadvantage to on-site construction operation, and easy occurrence of support splintering, this utility model provides a hydraulic support replacement device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic support replacement device, including a lifting plate frame and a front guide plate frame. The right end of the lifting plate frame is provided with a second slot, and the left end of the front guide plate frame is provided with a first slot. The lifting plate frame and the front guide plate frame are connected and fixed by an I-shaped frame installed in the first slot and the second slot. The front guide plate frame is provided with a front guide steel pipe groove, and the lifting plate frame is provided with a lifting steel pipe groove. A round steel shaft is installed on both the front guide steel pipe groove and the lifting steel pipe groove.

[0006] As a further improvement of this utility model, the raised plate frame includes a raised bottom plate and a raised top plate. The two ends of the raised bottom plate and the raised top plate are fixed by a raised large end plate and a raised small end plate, respectively, and the raised steel pipe groove is installed on the raised top plate.

[0007] As a further improvement of this utility model, the raised base plate is provided with a raised bracket for supporting the raised steel pipe groove.

[0008] As a further improvement of this utility model, the large end plate and the lifting bracket are connected and fixed by an inclined plate.

[0009] As a further improvement of this utility model, the front guide plate frame includes a front guide bottom plate and a front guide top plate. One end of the front guide top plate is fixedly connected through a front guide end plate, and the other end of the front guide top plate is fixed on the front guide bottom plate and extends to the same height as the bottom surface of the front guide bottom plate. The front guide steel pipe groove is installed on the front guide top plate.

[0010] As a further improvement of this utility model, a front guide bracket for supporting the front guide steel pipe groove is provided on the front guide base plate.

[0011] Compared with the prior art, the present invention has the following advantages: the device has a stable structure, is not easily deformed or damaged, and is easy to use for a long time. It facilitates the replacement of hydraulic supports on the working surface. The front guide plate is used for the transition of hydraulic supports during towing, preventing the hydraulic supports from jamming or getting stuck during operation. The lifting plate is used to connect to the forklift and raise the operating height of the hydraulic supports, thereby replacing the supports on the top of the forklift. It is quick and efficient, improves the replacement speed of hydraulic supports, and is simple to operate, thus improving construction efficiency. Attached Figure Description
