Description

Technical Field

[0001] The utility model belongs to the field of blasting, and particularly relates to a charging device for mixed emulsion explosives in water-containing blastholes in open-pit mines. Background Art

[0002] Open-pit mines use deep hole blasting, which requires mixed emulsion explosives to be delivered to the bottom of the blasthole. Due to rainy days in open-pit mines, the mud and rocks at the mouth of the blasthole become loose, and the explosive delivery pipe of the mixed explosive vehicle must be inserted to the bottom of the hole for loading to ensure the blasting effect. When the explosive delivery pipe of the mixed explosive vehicle contacts the mouth (wall) of the blasthole, slag and gravel slide to the bottom of the blasthole, resulting in blockage, which needs to be cleaned at any time. Therefore, this type of charging construction has low efficiency and high labor intensity. Utility Model Content

[0003] In view of the above problems, the utility model proposes a charging device for mixed emulsion explosives in water-containing blastholes in open-pit mines, comprising a frame, a roller and a limit rod arranged on the frame, wherein the roller is arranged parallel to the limit rod, and the limit rod is slidably connected to the frame.

[0004] Furthermore, the shape of the frame includes a rectangular frame, and the rollers and the limiting rods are parallel to the short sides of the frame and connected to the long sides of both sides of the frame.

[0005] Furthermore, bolts are arranged between the long sides of the frame, and the roller sleeves are arranged outside the bolts and are rollingly connected to the bolts.

[0006] Furthermore, the diameter of the limiting rod is smaller than the diameter of the frame body, a groove is provided on the frame body, and the limiting rod cooperates with the groove to achieve a sliding connection with the frame body.

[0007] Furthermore, the device includes a locking device capable of fixing the limiting rod and the frame.

[0008] Furthermore, the locking device includes elastic protrusions and locking grooves, and the multiple locking grooves are respectively arranged on the top surface and the bottom surface in the groove relative to each other. Two elastic protrusions are respectively arranged on both ends of the limiting rod relative to each other, and the elastic protrusions and the locking grooves cooperate with each other to fix the limiting rod and the frame.

[0009] Furthermore, the limiting rods include two, which are respectively arranged in parallel on both sides of the roller.

[0010] Furthermore, the rectangular frame of the frame body has a length of 600 mm and a width of 300 mm.

[0011] Furthermore, the frame is made of a φ30mm steel pipe.

[0012] Furthermore, the frame is connected by welding.

[0013] Compared with the prior art, this application has the following beneficial effects:

[0014] 1. By using the device during operation, the present application can effectively prevent the explosive delivery pipe of the mixed explosive vehicle from contacting the blast hole mouth (wall), and will not cause scum and gravel to slide to the bottom of the blast hole to cause hole blockage. During blasting operations, the explosive delivery pipe of the mixed explosive vehicle does not need to reach the bottom of the blast hole, thereby improving the charging efficiency of the mixed emulsion explosive vehicle, reducing the labor intensity of blasters, and improving the charging quality at the bottom of the blast hole.

[0015] 2. The present application provides a roller so that there is rolling friction between the explosive delivery tube of the mixed explosive vehicle and the roller. The rolling friction has small resistance, which facilitates the rise and fall of the explosive delivery tube of the mixed explosive vehicle in the blast hole, thereby improving operation efficiency.

[0016] 3. The present application sets a roller limit rod, which mainly plays a limiting role on the drug delivery pipe of the mixed explosive vehicle, so that the drug delivery pipe of the mixed explosive vehicle is placed between the roller and the limit rod to prevent it from shaking in the blast hole and bumping against the inner wall of the blast hole, causing slag and gravel to slide to the bottom of the blast hole, thereby reducing cleaning costs and achieving better blasting effects.

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, a charging device for mixed emulsion explosives in water-containing blastholes in open-pit mines includes a frame 1 and a roller 2 and a limit rod 3 arranged on the frame 1. The roller 2 is arranged parallel to the limit rod 3, and the limit rod 3 is slidably connected to the frame 1.

[0025] By placing the charging device at the mouth of the blasthole before the blasting operation, the charge delivery pipe of the mixed explosive vehicle can be effectively prevented from contacting the mouth (wall) of the blasthole, and scum and gravel will not slide down to the bottom of the blasthole to cause hole blockage. During the blasting operation, the charge delivery pipe of the mixed explosive vehicle does not need to reach the bottom of the blasthole, thereby improving the charging efficiency of the mixed emulsion explosive vehicle, reducing the labor intensity of blasters, and improving the charging quality at the bottom of the blasthole.

[0026] The frame 1 is in the shape of a rectangular frame, the rectangular frame of the frame 1 is 600 mm long and 300 mm wide, and the frame 1 is made of a φ30 mm steel pipe.

[0027] The roller 2 and the limit rod 3 are parallel to the short side of the frame 1 and connected to the long sides of the frame 1. During operation, the drug delivery pipe of the mixed explosive vehicle will contact and rub against the mouth (wall) of the blast hole. On the one hand, the roller 2 separates the drug delivery pipe of the mixed explosive vehicle from the mouth (wall) of the blast hole. On the other hand, the drug delivery pipe of the mixed explosive vehicle rises and falls in the blast hole, and there is rolling friction between the roller. The resistance of rolling friction is small, which facilitates the rise and fall of the drug delivery pipe of the mixed explosive vehicle in the blast hole, thereby improving the operation efficiency.

[0028] In some embodiments, the frame 1 is connected by welding.

[0029] like Figure 2 As shown, bolts are arranged between the long sides of the frame 1, and the roller 2 is sleeved outside the bolts and connected with the bolts in a rolling manner. Through holes are arranged on the long sides of the frame 1, and the bolts are fixed by nuts. The diameter of the through hole inside the roller 2 is larger than the outer diameter of the bolts. The roller 2 is sleeved on the bolts to achieve the rolling effect. The purpose of using bolts is to facilitate replacement. If the roller 2 is damaged, it is not necessary to replace the entire device. It is only necessary to remove the bolts and replace the roller 2, which reduces the cost.

[0030] The diameter of the limit rod 3 is smaller than the diameter of the frame 1, and a groove is provided on the frame 1, and the limit rod 3 cooperates with the groove to realize a sliding connection with the frame 1. The limit rod 3 can slide in the groove of the frame 1. When the drug delivery pipe of the mixed explosive vehicle enters the blast hole, the limit rod 3 slides to leave a larger space for convenient operation. When the drug delivery pipe of the mixed explosive vehicle has entered the blast hole and the preparation work before the explosive delivery is completed, the limit rod 3 is moved to limit the drug delivery pipe of the mixed explosive vehicle in a smaller space, so that the drug delivery pipe of the mixed explosive vehicle is placed between the roller 2 and the limit rod 3, to prevent shaking in the blast hole, bumping against the inner wall of the blast hole, causing scum and gravel to slide to the bottom of the blast hole, reducing the cleaning cost, and also making the blasting effect better.

[0031] The device comprises a locking device, which can fix the limiting rod 3 and the frame body 1.

[0032] The locking device includes elastic protrusions and locking grooves, and a plurality of the locking grooves are respectively arranged on the top surface and the bottom surface of the groove in a relative manner. Two elastic protrusions are respectively arranged on the two ends of the limit rod 3 in a relative manner, and the elastic protrusions and the locking grooves cooperate with each other to achieve the fixation of the limit rod 3 and the frame 1. When the elastic protrusions do not encounter the locking grooves, the elastic protrusions are compressed in the limit rod 3, and like the elastic protrusions on the umbrella, when they move to the corresponding locking groove position, the elastic protrusions stretch out and cooperate with the locking grooves to be fixed, and at this time, the limit rod 3 is fixed to the position of the frame 1. When a force parallel to the frame 1 is applied and the force reaches a certain degree, the elastic protrusions will be compressed when leaving the locking grooves, and at this time, the limit rod 3 can move on the frame 1. Repeating this process can achieve the function of moving and fixing the limit rod 3 on the frame 1.

[0033] When the explosives are fed into the explosive delivery tube of the mixed explosive truck, shaking will occur. At this time, the limit rod 3 needs to be fixed on the frame 1 to fix the explosive delivery tube of the mixed explosive truck within a certain range to prevent large shaking from causing collision with the inner wall of the blasthole and causing slag and gravel to slide to the bottom of the blasthole.

[0034] In some embodiments, the limiting rod 3 includes two, which are respectively arranged in parallel on both sides of the roller 2. When one side is damaged, it is impossible to limit the drug delivery tube of the mixed explosive vehicle, and the limiting rod 3 on the other side can be used in time to limit the drug delivery tube of the mixed explosive vehicle. This design can deal with the situation where one side of the limiting rod 3 is damaged, and timely adjustment can be made, thereby improving efficiency and saving costs.

[0035] like Figure 3As shown, when conducting mine blasting, a charging device is first placed at the mouth of the blasthole, and a frame 1 is placed on the mine body around the mouth of the blasthole. The explosive delivery pipe of the mixed explosive vehicle moves to the bottom of the blasthole with the help of rollers 2, stops after moving to a certain position, and adjusts the limit rod 3 so that the roller 2 and the limit rod 3 limit the explosive delivery pipe of the mixed explosive vehicle to prevent the vibration in the blasthole from knocking the soil and rocks on the inner wall of the blasthole to the bottom of the blasthole, affecting the blasting effect, and also reducing the process of manually clearing the soil and rocks from the blasthole.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
