Problems solved by technology

[0002] During the construction of mine roadways, dust control has been paid more and more attention. Dust removal fans have been widely used due to their good dust control and dust removal effects. When the air duct is still hung, the top single-point suspension is adopted. During the operation of the dust removal fan, when the excavator retreats, the negative pressure air duct has a large margin, and the air duct is prone to sideways under the action of suction, resulting in The ventilation section decreases sharply, the air suction volume decreases, the dust removal effect is poor, and even the dust removal fan is damaged

Embodiment Construction

[0017] Such as figure 1 Shown, a kind of stretch recoverer of negative pressure blower, it comprises that steel wire rope 1 is suspended on mine road wall. A negative pressure air cylinder 2 is set, and a group of hanging rings 1a corresponding to the steel wire rope 1 are arranged on the outer wall of the negative pressure air cylinder 2, so that the negative pressure air cylinder 2 is suspended on the steel wire rope 1, and the negative pressure air cylinder can be used 2. Move back and forth along the wire rope 1.

[0018] A vertical vertical rod 6 is set, a rope hole 3a corresponding to the steel wire rope 1 is provided on the top of the vertical rod 6, a screw rod 6a coaxial with the vertical rod 6 is provided at the bottom of the vertical rod 6, and an additional The thick hollow tube 3 is provided with a gear case 6b at the upper end of the thickened hollow tube 3 .

[0019] The lower end of the screw rod 6a passes through the gear box 6b and then extends into the tub...

Abstract

The invention provides a tensile recovery device with a negative pressure air duct. The tensile recovery device comprises a steel wire rope (1) suspended on a mine tunnel; the negative pressure air duct (2) is arranged on the steel wire rope (1) in a penetrating manner. The tensile recovery device is characterized in that a vertical rod (6a) is arranged; an air duct containing metal frame (4) correspondingly matched with the negative pressure air duct (2) is arranged on the vertical rod (6a); a screw rod (6a) is arranged at the lower end of the vertical rod (6a); a gearbox (6b) is arranged on the screw rod (6a) in a penetrating manner; a thickened hollow pipe (3) is arranged at the lower part of the gearbox (6b); the screw rod (6a) is correspondingly matched with the thickened hollow pipe (3); a group of mounting screw holes (3a) is formed in the thickened hollow pipe (3). The tensile recovery device provided by the invention has the advantages that the structure is simple, the use is convenient, the direct mounting on existing production equipment is facilitated, the inclination of the negative pressure air duct can be avoided, and the air suction amount of the air duct is effectively ensured.

Description

Technical field: [0001] The invention provides a storage device, specifically a stretching recoverer for a negative pressure air cylinder. Background technique: [0002] During the construction of mine roadways, dust control has been paid more and more attention. Dust removal fans have been widely used due to their good dust control and dust removal effects. When the air duct is still hung, the top single-point suspension is adopted. During the operation of the dust removal fan, when the excavator retreats, the negative pressure air duct has a large margin, and the air duct is prone to sideways under the action of suction, resulting in The ventilation section decreases sharply, the air suction volume decreases, the dust removal effect is poor, and even the dust removal fan is damaged. In addition, when the mine tunnel is being excavated, the diameter of the tunnel often changes due to the indeterminate direction of the vein. Invention content: [0003] In order to overco...
