[0028] The technical solution of the present application is clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0029] Definition: Balancing device pressure plate, from the instruction manual of the YXZ multi-rope hoist tension automatic balancing suspension device of Xuzhou Coal Mine Safety Equipment Manufacturing Co., Ltd.

[0030] The YXZ multi-rope hoist tension automatic balancing suspension device consists of three parts: a wedge-shaped rope ring, a hydraulic balancing system, and a load-bearing structural component. The single-frame device consists of a wedge-shaped rope ring, a middle plate, an upper connecting pin, a baffle, a pressure plate (balance device pressure plate), a side plate, a connecting cylinder, a connecting assembly, a pad, a middle connecting pin, a reversing fork, and a lower connecting pin. The middle plate and the side plate form a pull-out buckle structure through the baffle, the pressure plate, the pad, the middle connecting pin, and the connecting cylinder, and then connect to the upper wedge-shaped rope ring through the upper connecting pin, and connect to the lower container through the reversing fork, the lower connecting pin, and the four corner plates. Multiple such structures plus connecting assemblies (hose, valve, through pipe) form a tension automatic balancing suspension device.

[0031] like Figure 1-4 As shown, a multi-rope friction hoist maintenance safety shed includes two shed plates and two sets of fixing devices, each set of the fixing devices includes an upper pressure bar 4, a lower pressure bar 5, two transverse fixing brackets 1 and two longitudinal fixing brackets 2;

[0032] The length of the lower press strip 5 is longer than that of the upper press strip 4; the upper press strip 4 is arranged in parallel with the lower press strip 5, and the perpendicular midline of the upper press strip 4 coincides with the perpendicular midline of the lower press strip 5;

[0033] There are two longitudinal fixing brackets 2, wherein one end of one longitudinal fixing bracket 2 is fixed to one end of the upper bead 4, and the other end is vertically mounted on the lower bead 5; one end of the other longitudinal fixing bracket 2 is fixed to the other end of the upper bead 4, and the other end is vertically mounted on the lower bead 5;

[0034] There are two transverse fixing brackets 1, wherein one end of one transverse fixing bracket 1 is fixed to one end of the upper bead 4, and the other end is fixed to the end of the lower bead 5 on this side; one end of the other transverse fixing bracket 1 is fixed to the other end of the upper bead 4, and the other end is fixed to the end of the lower bead 5 on this side;

[0035] Each of the shelf plates 3 is supported by two transverse fixing brackets 1 on the same side of two sets of fixing devices;

[0036] The two groups of fixing devices are arranged in parallel, and the space formed by the two upper pressure strips 4 in the two groups of fixing devices is the space in which the safety shed is installed on the multi-rope friction hoist.

[0037] Since the upper pressure strip 4 is arranged in parallel with the lower pressure strip 5 and the length of the lower pressure strip 5 is longer than the upper pressure strip 4, the transverse fixing bracket 1 has an angle with respect to the upper pressure strip 4 and the lower pressure strip 5 respectively. Preferably, the transverse fixing bracket 1 has an angle of 17 degrees with the lower pressure strip 5.

[0038] When in use, the upper pressure strip 4, the lower pressure strip 5 and the longitudinal fixing bracket 2 are fixed above the pressure plate of the balancing device by bolts.

[0040] In order to facilitate disassembly, the shelf 3 is connected to the transverse fixing bracket 1 by bolts, and the upper pressure strip 4 is connected to the longitudinal fixing bracket 2 by bolts.

[0041] In order to ensure the overall stability, the upper pressure strip 4 and the lower pressure strip 5 are both made of steel plates; and the shelf 3 is made of aluminum plates.

[0042] In order to ensure the stability of the shelf, a limiting plate is further provided at the connecting end of the transverse fixing bracket 1 and the lower pressing strip 5 .

[0051] Step 2: Use a longitudinal fixed bracket 2 to connect the upper pressure strip 4 and the lower pressure strip 5, with a total of 2 groups; in each group, the longitudinal fixed bracket 2 and the upper pressure strip 4 are connected by bolts, and the longitudinal fixed bracket 2 and the lower pressure strip 5 are connected by screws fixed above the pressure plate of the balancing device.

[0052] In the third step, the transverse fixing bracket 1 is connected to the upper pressure strip 4 and the lower pressure strip 5 respectively by bolt connection, with two groups in total.

[0053] The fourth step is to place two groups of upper pressure strips 4, lower pressure strips 5, transverse fixing brackets 1, and longitudinal fixing brackets 2 in parallel, and use the space formed by the four ends of the upper pressure strips 4 in the two groups as the installation space, and the installation space is installed at the fixed end of the balancing device at the position of the fixing plate (balancing device pressure plate) at the end of the cylinder body as the bracket fixing position;
