Abstract
The utility model relates to an upright post protective device of a hydraulic bracket. The protective device comprises a protective sleeve. The protective sleeve is unfolded to form a fan-shaped annular protective plate. Connection holes are formed in two side edges of the protective plate. The corresponding connection holes in two side edges are connected through connection springs to form the protective sleeve. The protective device disclosed by the utility model is sleeved on an upright post of the hydraulic bracket; and therefore, the collision of rocks or coal briquettes can be effectively blocked; a polished surface can be prevented from being damaged so that the upright post is prevented from being damaged; the economical loss is effectively reduced; the production safety is enhanced; and the protective device has the advantages of being simple for manufacture and convenient for installation and maintenance.
Description
Technical field
The utility model relates to a kind of hydraulic support column protective device.
Background technology
Hydraulic support is the works that is used for controlling coal-face mine pressure, adopts the face ore deposit and presses the form of carrying in addition to act on the hydraulic support.Hydraulic support is the important component part of fully-mechanized mining equipment, and it can reliably and effectively support and control the top board of work plane, isolates the goaf, prevents that spoil from getting into stope and advancing conveyer.It and the supporting use of coal-winning machine; Realize the coal mining comprehensive mechanization, roof control lags behind the contradiction of coal work in the solution mechanical coal mining work, further improves the usefulness of coal mining and haulage device; Alleviate the labour intensity of coal miner, ensure the life security of coal miner to greatest extent.But in the recovery process, tend to because work plane is put the burnishing surface of the expansion link of protective cradle column when shaking big gun, the sillar of avoiding blowing up or the collision of coal cinder, the impaired column that causes of column burnishing surface is damaged, and causes security incident and economic loss.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of hydraulic support column protective device is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The hydraulic support column protective device of the utility model; This protective device comprises protective sleeve; The expanded view of described protective sleeve is provided with connecting hole for fan ring protection plate on the dual-side of protected apron, be connected to form protective sleeve with the connection spring between the connecting hole of dual-side correspondence.Because use spring to connect, this device can be regulated size automatically during lifting column, and can not support bad column protective device.
In order to prevent that the column protective device from gliding, the top is provided with fixed card on protective sleeve.
The protector of the utility model is sleeved on the column of hydraulic support, can effectively stops the collision of sillar or coal cinder, avoid the impaired column that causes of burnishing surface to damage, effectively reduced economic loss, improved the safety of producing.This protective tissue is made simple, easy for installation, is convenient to safeguard that the operation and the cost that do not influence hydraulic support are low, have protected expensive hydraulic support column with less cost.

Fig. 2 is the rear elevation of the utility model.
Fig. 3 is the expansion sketch map of the protective sleeve in this utility model.
The specific embodiment
The hydraulic support column protective device of the utility model; This protective device comprises protective sleeve 2; The expanded view of described protective sleeve 2 is provided with connecting hole 3 for fan ring protection plate on the dual-side of protected apron, be connected to form protective sleeve with connecting spring 4 between the connecting hole of dual-side correspondence.Because use spring to connect, this device can be regulated size automatically during lifting column, and can not support bad column protective device.
In order to prevent that the column protective device from gliding, the top is provided with fixed card 1 on protective sleeve 2.
According to actual needs, select 1.5 meters long belts, it is cut into the fan-shaped of length of side 1430mm, arc length is respectively 1100mm, 590mm.At fan-shaped both sides punching, diameter 10mm, 150mm beats first hole apart from the short arc limit, and spacing 300mm makes a call to 5 successively then, totally 6 hole (see figure 3)s.At the screw of fixing diameter 10mm on all holes, Yi Bian the wherein fixing simultaneously spring of going up diameter 10mm, long 160mm.During use fan-shaped belt is surrounded on the bracket upright post, be rolled into tapered cylinder, entangle bracket upright post; The other end of spring is fixed on the screw of fan-shaped belt another side, with the fan-shaped belt both sides (see figure 2) that connects together, stamps clamp on the top of column protective device then with spring; It is that the band iron of 40mm is processed that clamp has width; Two is fastening with the screw of diameter 10mm, prevents that the column protective device from gliding, owing to use spring to connect; This device can be regulated size automatically during lifting column, and can not support bad column protective device.
Claims (2)
