Description

Technical Field

[0001] The utility model relates to the technical field of iron ore mining, in particular to a hole plugging device for a blasting bell mouth. Background Art

[0002] During the ore mining process, it is necessary to mine by blasting, which requires setting the blasting bell mouth at a set position. After placing explosives in the blasting hole, the blasting bell mouth needs to be blocked. The existing blocking methods are divided into filling and blocking holes or blocking holes with hole pluggers. The method of blocking holes with hole pluggers is more expensive and requires the purchase of a large number of hole pluggers; while the filling and blocking method is mainly to block holes with blocking materials. For example, patent application No. 202180098005.0 discloses a wedging device for blocking blasting holes containing explosives. The patent records that the wedging device 10 is inserted into the blasting hole 12 together with the explosive 14, and the top blocking material 26 and the bottom blocking material 28 are respectively located at the two ends of the wedging device 10. In some applications, the top blocking material 26 can be located outside the blasting hole 12. In other applications, when the viscosity of the explosive 14 is sufficient to fix the wedging device 10, the bottom blocking material 28 can be omitted, and the wedging device 10 can be placed directly on the explosive 14;

[0003] In the prior art, the top plugging material 26 is mainly filled manually, but this filling method easily causes workers to accidentally touch the beam rod of the lead wire, which poses a great safety risk. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a plugging device for a blasting bell mouth, so as to solve the problem of low safety of the top plugging material filling method of the blasting hole in the prior art described in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a device for plugging a blasting bell mouth, comprising:

[0006] two support plates, parallel to each other;

[0007] two telescopic rods, located between the two support plates;

[0008] Four slide plates are fixedly connected to the two ends of the two telescopic rods respectively, and the slide plates are movably arranged on the support plates at corresponding positions;

[0009] Two enclosures are fixedly connected to opposite surfaces of two support plates, and the side walls corresponding to the positions of the two support plates are connected by elastic retaining cloth;

[0010] Wherein, the two enclosures are respectively provided with positioning grooves opening downwards.

[0011] Preferably: a baffle plate and a positioning plate are fixedly connected to the middle plate body of the enclosure, a screw rod is connected to the positioning plate via threads, and the baffle plate and the positioning plate are respectively located on both sides of the positioning groove.

[0012] Preferably, the slide plate is U-shaped, and two opposite side walls of the slide plate are respectively provided with slide grooves, and a limit plate is provided at a position on the support plate corresponding to the slide groove, and the limit plate slides into the slide groove, and a first locking bolt is provided on the slide plate.

[0013] Preferably, the enclosure is U-shaped or arc-shaped.

[0014] The beneficial effects of adopting the above technical solution are:

[0015] The support plate set up in the present application can be laid horizontally on the ground, and the two enclosures can be extended into the blasting hole. The distance between the two support plates is then adjusted by a telescopic rod so that the two enclosures can be located at the center of the blasting hole. Workers then use a shovel to pour the filling material between the two enclosures to complete the filling of the blocking material. The positioning groove on the enclosure of the present application is used to press on the crossbeam plate of the lead wire, which can prevent the crossbeam plate from moving after being accidentally touched, thereby improving safety.

DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3 In the first embodiment, a device for plugging a blasting bell mouth includes:

[0022] Two support plates 10, parallel to each other;

[0023] Two telescopic rods 30 are located between the two support plates 10;

[0024] Four slide plates 20 are respectively fixedly connected to the two ends of the two telescopic rods 30, and the slide plates 20 are movably arranged on the support plates 10 at corresponding positions;

[0025] Two enclosures 40 are respectively fixedly connected to opposite surfaces of two support plates 10, and the side walls of the two support plates 10 corresponding to each other are connected by an elastic stop cloth 42;

[0026] The two enclosure plates 40 are respectively provided with positioning grooves 41 with openings facing downwards.

[0027] This embodiment is implemented as follows:

[0028] When the present application is in use, firstly the distance between the two support plates 10 is adjusted according to the size of the blasting hole, mainly by means of the telescopic rod 30, and the position of the slide plate 20 on the support plate 10 can also be adjusted, and then the two enclosures 40 are placed on the crossbeam of the explosive lifting rope so that the two enclosures 40 press the crossbeam, which makes it difficult for the crossbeam to be moved when the crossbeam is accidentally touched, and then the worker uses a shovel to fill the filler between the two enclosures 40, which can make the loading process more centered, make the filling more uniform, and improve safety.

[0029] Compared with the prior art, the advantages of the present application are improved safety and improved filling uniformity.

[0030] See also Figure 1 The baffle plate 50 and the positioning plate 52 are fixedly connected to the middle plate body of the enclosure 40, and the positioning plate 52 is threadedly connected to the screw 51, and the baffle plate 50 and the positioning plate 52 are respectively located on both sides of the positioning groove 41;

[0031] By rotating the screw rod 51 , it can move on the positioning plate 52 , so that the screw rod 51 can clamp the cross beam plate of the explosive suspension rope on the baffle plate 50 , making the cross beam plate more difficult to be moved, further improving stability.

[0032] See also Figure 1 , 2 The slide plate 20 is U-shaped, and two opposite side walls of the slide plate 20 are respectively provided with slide grooves 11, and a limit plate 21 is provided at a position corresponding to the slide groove 11 on the support plate 10, and the limit plate 21 slides into the slide groove 11, and a first locking bolt 22 is provided on the slide plate 20;

[0033] By setting the limiting plate 21 to penetrate the sliding groove 11 , the sliding plate 20 can slide on the supporting plate 10 , and the first locking bolt 22 can fix the sliding plate 20 on the supporting plate 10 .

[0034] See also Figure 1 , 3, the enclosure 40 is U-shaped or arc-shaped; setting the enclosure in an arc or U-shape can reduce the amount of elastic blocking cloth 42 used.

[0035] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
