Abstract
The utility model relates to a dedicated auxiliary device for mine support, which relates to a hydraulic prop lifting device used for lifting single metal friction props on extracting faces with pump stations and mainly comprises a clamp assembly, an annular hook, an outer liquid injecting one-way valve, a U-shaped clamp, an unloading hand wheel, and a top cover, an oil cylinder, an active column, a reset spring, a base body, a piston and a support column head which are the components of a hydraulic propulsion system, etc. The utility model has the advantages of simple structure, light weight, convenience for carrying, convenient liquid injecting, unloading and hooking operations, and high prop lifting and lowering speeds; besides, the work efficiency is increased, and the setting pressure is free from the influence of artificial factors.
Description
The utility model relates to mine support equipment, further is the special equipment hydraulic lifting unit that down-hole stope elemental metals friction prop setting prop is used.
In existing setting prop equipment, mainly contain the hand-hydraulic prop raising tool, it is to provide hydraulic oil to force on the post alive by a handlance in the body to move, the realization setting prop.Its shortcoming is: 1. manually-operated handlance, and setting prop speed is slow, and labour intensity is big; 2. the size of setting load is subjected to operator's quality influence.See the automatic prop raising tool of high-performance hydraulic pressure that " Wujin, Changzhou fail safe instrument factory " produces recently, similar with a kind of external poured hydraulic lifting unit that we once designed at first.It is the reprint of hydraulic prop basically.Its shortcoming is: 1. uses the triple-use valve unloading of hydraulic prop, needs the operator carry the unloading handgrip, and must two people operation during unloading.2. liquid injecting mouth is unidirectional, and operating position is restricted.Weight ratio big, carry inconvenience.
Purpose of design of the present utility model is to overcome weak point of the prior art, and provide a kind of simple in structure, in light weight, be easy to carry fluid injection, unloading, the easy to operate external poured hydraulic lifting unit of hook.
Purpose of design of the present utility model can reach by following measure:
In the external poured hydraulic lifting unit that constitutes by clamp assembly 1, hook, hydraulic propelling system, outer fluid injection parts, unloading parts, its hydraulic propelling system comprises top cover, oil cylinder, live post, base body, piston, supporting column cap, and its outer fluid injection parts adopt independently fluid injection one way valve.
Purpose of design of the present utility model can also reach by following measure:
Its independently the fluid injection one way valve be to be connected in fluid injection one way valve 15 on the joint 17 of base body 14 with " U " shape card 16.
Its unloading parts are made of the unloading valve pad 3 of the unloading hole that is positioned at supporting column cap 28, unloading handwheel 4 and unloading handwheel 4 axle heads.
Its hook is the annular hook 7 that is enclosed within oil cylinder 8 upper ends, can rotates around oil cylinder.
In its post 9 of living reset tension spring 21 is arranged.
The utility model compared with prior art has following advantage:
1. simple in structure, in light weight, be easy to carry.
2. adopt the one way valve fluid injection that connects with " U " shape card, on a vertical plane can be by any direction fluid injection, promptly easy to operate.
3. unloading manner is simple, only needs loosening unloading handwheel.
4. adopt external poured and structure such as automatically reset, setting prop, to fall post speed fast, increases work efficiency; Setting load only changes with pumping plant pressure, is not subjected to artificial factor.
5. the structure of hook can be rotated around oil cylinder, is convenient to operation.
The drawing of accompanying drawing is described as follows:
Fig. 1: the utility model structural representation general assembly drawing
Fig. 2: A-A partial sectional view among Fig. 1
Fig. 3: the structural representation vertical view of hook
Fig. 4: the structural representation front view of hook
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows the utility model structure, and it is made up of clamp assembly 1, hydraulic propelling system, fluid injection one way valve 15.Hydraulic propelling system is made up of the major parts such as unloading handwheel 4 on top cover 5, hook 7, oil cylinder 8, the post 9 of living, reset tension spring 21, spring hangers 22, base body 14, piston 27, supporting column cap 28, the supporting column cap.Base body 14 is threaded with oil cylinder 8 usefulness, and with 12 sealings of " O " shape sealing ring, piston 27 is enclosed within on the post 9 alive and fixes with axial back-up ring 18, and piston 27 is used 19,11 sealings of " O " shape sealing ring respectively with the post 9 of living, oil cylinder 8; Living has reset tension spring 21 in the post 9, and the lower end of extension spring hangs in the hook of base body 14, and the upper end hangs over and supports on the column cap 28 spring hangers 22 welded together; Supporting column cap 28 is contained in the upper end of post 9 alive, connects with steel wire 25, with 23 sealings of " O " shape sealing ring.The axle head of unloading handwheel 4 is the groove shape, unloading valve pad 3 is equipped with in the inside.Unloading handwheel 4 usefulness screw threads are screwed on the supporting column cap 28, are drilled with the unloading hole vertical with unloading handwheel 4 on the supporting column cap 28.Hook 7 is enclosed within the upper end of oil cylinder 8, and can rotate around oil cylinder 8, be subjected to the constraint of top cover 5 on it, and top cover 5 inwalls is equipped with guide ring 6, and outer wall is connected with oil cylinder 8 with screw thread.Clamp assembly 1 is used on the HSY-5 hydraulic lifting unit, is connected with supporting column cap 28 with pin 2.Fluid injection one way valve 15 is to be connected on the joint 17 of base body 14 with " U " shape card 16, and its model adopts YQ04 type one way valve.Remaining parts has: 10,13,20,24 are anti-extrusion ring, and 26 are cottor pin.
Structure when Fig. 2 shows 1 side-looking of clamp assembly.
Fig. 3,4 shows the shape and the structure of annular hook 7.
Operating principle: the post that first hook 7 with prop raising tool hangs over the metal friction pillar is locked, and clamp is clamped on the plunger tube of metal friction pillar, fluid injection gun is enclosed within on the one way valve 15 the beginning fluid injection again.Liquid enters oil cylinder 8 cavity of resorptions, forces on the post alive 9 of prop raising tool to move, and up to the contact top board, reach pumping plant pressure, pounds tight horizontal wedge, finishes the setting prop process of friction prop.Loosening then unloading handwheel 4, the liquid in the oil cylinder 8 and post 9 bodies of living is excessive by the unloading hole, lives post 9 under the effect of reset tension spring 21, resets fast.
