Description

Technical Field

[0001] This utility model relates to the field of hydraulic support manufacturing technology, and in particular to a hydraulic support tilting platform. Background Technology

[0002] Hydraulic supports are key equipment used in fully mechanized coal mining faces to support the roof and ensure operational safety. The hydraulic supports in a comprehensive maintenance plant usually refer to the work process and related technologies for their maintenance, repair, or refurbishment.

[0003] In the production practice of fully mechanized mining equipment repair shops (repair plants), the assembly and maintenance of hydraulic supports are characterized by high frequency. As for the support flipping process, the current process generally adopts the traditional mode of crane hoisting combined with manual positioning. During the flipping process from horizontal to vertical, due to the shift of the support's center of gravity and the asymmetrical characteristics of its structure, large-scale swinging is easily induced, which makes accurate positioning difficult and creates safety risks. During maintenance, it is often necessary to reinstall the side guard plates. The reinstallation process of the side guard plates is often carried out by manual hammering and wedging, which has obvious problems such as low work efficiency, excessive physical exertion, and excessive noise pollution. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that during the flipping process of a hydraulic support from a horizontal to a vertical state, the center of gravity of the support shifts and the asymmetrical structure is prone to large-scale swinging, which makes accurate positioning difficult and creates safety risks. During maintenance, it is often necessary to reinstall the side guard plates, and the reinstallation process is often done by manually hammering and wedging them in, which has obvious problems such as low work efficiency, excessive physical exertion, and excessive noise pollution.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic support tilting platform, including a mounting frame, a connecting block fixedly mounted at the rear end of the mounting frame, a tilting plate provided on the connecting block, a first triangular connecting frame fixedly connected to the lower end of the tilting plate, the first triangular connecting frame being rotatably connected to the connecting block, a mounting plate fixedly connected to the top end of the tilting plate, a fixing mechanism provided on the mounting plate, and two symmetrically distributed tilting mechanisms provided between the tilting plate and the mounting frame; the fixing mechanism includes fixing angle steels fixedly connected to both ends of the mounting plate, and multiple mounting angle steels fixedly connected to the fixing angle steels, wherein two of the mounting angle steels are distributed opposite to each other. On both sides of the mounting plate, the remaining mounting angle steel is installed near either side. A mechanical jack is installed between two adjacent mounting angle steels. The mechanical jack is fixedly connected to the mounting angle steel at its rear end. The output end of the mechanical jack passes through the mounting angle steel at its front end. When fixing the hydraulic support, the hydraulic support is first hoisted onto the mounting plate, and side guard plates are installed at both ends of the hydraulic support. The mechanical jack outputs pressure to press and fix the side guard plates at both ends of the hydraulic support. After pressing, the hydraulic support can be fixed at both ends. The hydraulic support can be quickly rotated after being fixed and installed by the flipping mechanism for easy transportation in the next step.

[0006] In a preferred embodiment, a locking block is provided in the middle of the fixed angle steel, and the locking block is also provided with multiple spare parts. The hydraulic support can be positioned by the locking block, which facilitates the fixing of the hydraulic support.

The position of the adjustment holes can be adjusted by means of the design of the clamping block, which can adapt to different specifications and models of hydraulic supports and facilitate assembly and fixing operations.

[0008] In a preferred embodiment, the flipping mechanism includes a cylinder mounting bracket fixedly installed at the lower end of the mounting frame, a cylinder rotatably mounted at the cylinder mounting bracket, and a second triangular connecting bracket fixedly connected to the lower end of the flipping plate. The second triangular connecting bracket is rotatably connected to the output end of the cylinder, and the flipping plate can be flipped by the output of the cylinder, thereby causing the hydraulic support fixed on the mounting plate to flip.

[0009] In a preferred embodiment, a reinforcing plate is fixedly connected between the fixed angle steel and the mounting angle steel at the installation jack, which can enhance the stability of the mounting angle steel.

[0010] In a preferred embodiment, omnidirectional casters are fixedly installed at the four corners of the bottom of the mounting frame, which can improve the mobility of the device.

[0011] In a preferred embodiment, the cylinder is equipped with a hydraulic interface at both the input and output ends. The hydraulic interface is connected to an external hydraulic station pipeline via a high-pressure hose. The external hydraulic pipeline can enable the cylinders at both ends to operate synchronously through devices such as a flow divider valve, thereby providing a stable hydraulic fluid for the output operation of the cylinder.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model can use a mechanical jack to output pressure, which can simultaneously tighten and fix both ends of the hydraulic support. With the help of the flipping mechanism, the hydraulic support can be quickly rotated after maintenance for easy transportation. The side plate can also be fixed and installed simultaneously during operation without the need for hoisting and flipping, which improves production efficiency and quality and has strong practicality.

The mechanical jack 13 is fixedly connected to the installation angle steel 9 at its rear end. The output end of the mechanical jack 13 passes through the installation angle steel 9 at its front end. When fixing the hydraulic support, the hydraulic support is first hoisted onto the mounting plate 8, and side guard plates are installed at both ends of the hydraulic support. The mechanical jack 13 outputs pressure to press and fix the side guard plates at both ends of the hydraulic support. After pressing, the hydraulic support can be fixed at both ends. The hydraulic support can be quickly rotated after being fixed and installed by the flipping mechanism for easy transportation in the next step.

[0022] like Figure 1-4 As shown, a locking block 11 is provided in the middle of the fixed angle steel 12. The locking block 11 is also provided with multiple spare parts. The hydraulic support can be positioned by the locking block 11, which facilitates the fixing of the hydraulic support.

[0023] like Figure 1-4 As shown, the fixed angle steel 12 is provided with multiple spaced adjustment holes 10. The lower end of the locking block 11 is fixedly connected to a fixing nut 17. The outer circumference of the fixing nut 17 is threaded with a fixing rod 16. The fixing rod 16 is screwed to the bottom surface of the fixed angle steel 12.

[0028] Working principle: When fixing the hydraulic support, the hydraulic support is first hoisted onto the mounting plate 8, and side guard plates are installed at both ends of the hydraulic support. Pressure is output through mechanical jacks 13, and then the side guard plates are pressed by the mechanical jacks 13 on both sides to achieve the function of fixing the side guard plates. After installation and fixing, the clamping force of the mechanical jacks 13 on both sides is maintained to fix the two ends of the hydraulic support. The output of cylinder 3, in conjunction with the second triangular connecting frame 15, drives the tilting plate 5 to change angle, thereby driving the mounting plate 8 and the hydraulic support on the mounting plate 8 to tilt. This can quickly tilt and stand the hydraulic support upright for the next step of transportation.
