The utility model relates to a mining hydraulic prop's of taking cap of a column supporting accessory specifically is mining hydraulic prop and cap of a column anti-falling device. The problem of the mining hydraulic prop of taking the cap of a column easily take place the potential safety hazard that the cap of a column falls and injures people's accident and bring because of lacking adapting unit between cap of a column and the mining hydraulic prop is solved, so provide a mining hydraulic prop and cap of a column anti falling device. The device comprises staple bolt and at least one connecting plate, the one end of connecting plate and staple bolt fixed connection, the other end is opened has and is used for being connected the connecting hole with the cap. The device can effectively prevent the phenomenon that the post cap falls to hurt people after the post is retracted, and when the post is retracted, the post cap is not easy to fall because the post cap is tightly connected with the device, so that the operation is simple and convenient, and the safety performance is good.
Description
Technical Field
The utility model relates to a mining hydraulic prop's of taking cap of a column supporting accessory specifically is mining hydraulic prop and cap of a column anti-falling device.
Background
The advance maintenance of two roadways on a working face is always the most important in the management of a coal mine roof, when the roof is complete and no pressure appears, a single capped point column is adopted for supporting, a single hydraulic prop is matched with the roof in a form that a leg and a column cap are tops, and an I-shaped steel beam column cap with the length of 400mm and the length of 11# and a DZ31.5-30/100 type single hydraulic prop are selected according to the actual height of a roadway on site. Namely, three rows of capped point columns are additionally arranged within 10m of the coal wall of the front working face, two rows of capped point columns are additionally arranged within 10-25m of the coal wall of the front working face, and the distance between the capped point columns is 0.8 m. Because the iron column cap is used, the working face is fast in propelling speed, and more monomers need to be recovered in the recovery process, the accident that the column cap falls off to hurt people often occurs in the process of recovery when the monomer column cap is added, and great potential safety hazards are brought to underground work of the coal mine.
Disclosure of Invention
The utility model discloses a solve and lack adapting unit between cap and the mining hydraulic prop, therefore take the mining hydraulic prop of cap to easily take place the cap and drop the problem of the potential safety hazard that the wounded accident brought, the event provides a mining hydraulic prop and cap anti-falling device.
The utility model discloses an adopt following technical scheme to realize: the anti-falling device for the mining single hydraulic prop and the column cap comprises a hoop and at least one connecting plate, wherein one end of the connecting plate is fixedly connected with the hoop, and the other end of the connecting plate is provided with a connecting hole used for being connected with the column cap.
When the device is used, firstly, the hole is punched in the middle of the column cap, one end of the connecting plate of the device, which is provided with the connecting hole, is connected with the hole in the column cap through the bolt, the hoop of the device is fixedly sleeved on the single hydraulic prop, and when the device is used in the extraction process, a connecting part is arranged between the column cap and the mining single hydraulic prop, so that the potential safety hazard caused by the accident that the column cap falls off and hurts people is greatly reduced.
The utility model discloses produced beneficial effect as follows: 1) the accident of hurting people caused by the falling of the column cap is greatly reduced, and operators and managers feel relieved; 2) the labor intensity of workers is reduced, the recovery rate is improved, and the method has great safety and practical value and great social and economic values; 3) the device of the utility model is simple in design, practical, portable and ability used repeatedly, required raw and other materials are simple band iron, bolt and simple and easy welding process. The materials are all daily leftover materials, and the total processing cost is not more than 50 yuan. Has wide market prospect.

Wherein: 1-anchor ear, 2-connecting plate, 3-connecting hole.
Detailed Description
The anti-falling device for the mining single hydraulic prop and the column cap is characterized by comprising an anchor ear 1 and at least one connecting plate 2, wherein one end of the connecting plate 2 is fixedly connected with the anchor ear 1, and the other end of the connecting plate is provided with a connecting hole 3 used for being connected with the column cap.
When the device is used, firstly, the hole is punched in the middle of the column cap, one end of a connecting plate 1 of the device, which is provided with a connecting hole 3, is connected with the hole on the column cap through a bolt, and a hoop 2 of the device is fixedly sleeved on the single hydraulic prop.
During the concrete implementation, staple bolt 1 is two half formula staple bolts that two halves piece is constituteed, not only makes the cover more firm when solid on hydraulic prop, also easy to assemble dismantlement when using moreover. The two connecting plates 2 are arranged, one ends of the two connecting plates 2 are fixedly connected with the two half pieces of the two half-type hoops 1 respectively, and therefore the column cap is more firmly connected with the single hydraulic prop. Every the one end of connecting plate 2 respectively with the median fixed connection of half each of piece of two half formula staple bolts 1, two promptly connecting plate 2 symmetric distribution in the both sides of hydraulic prop, steadiness when having further strengthened cap and hydraulic prop and being connected. The middle part of the connecting plate 2 is arc-shaped, and the convex direction of the arc is the direction far away from the hoop 1. The middle part of the connecting plate 2 is bent to divide the connecting plate 2 into four sections, and the bending convex direction of the middle part of the connecting plate 2 is the direction far away from the hoop 1, so that the device can avoid the convex part on the upper part of the single hydraulic prop when the single hydraulic prop is connected with a column cap. The length of the four sections of the connecting plate 2 is as follows from the end connected with the hoop 1: 65mm, 70mm, 60mm, 40mm, the size of injecing makes the hydraulic prop of monomer and cap use the device to connect the time cooperation more firm.
In the embodiment, the hoop 1 and the connecting plate 2 are made of flat iron with the width of 40mm, and are made of daily leftover materials, so that the cost is low and the use is convenient.
Utilize this device can be connected with the cap post with single body hydraulic prop, and does not influence the effect of strutting, when needs use the point post of taking the cap, utilize this device to connect, when not needing this device, can come cap post and single body hydraulic prop separation again through dismantling the bolt on cap post and the connecting hole 3, can not influence single body hydraulic prop's normal maintenance and use yet.
