Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of emulsion explosives, in particular to a powder roll clamp for emulsion explosives. Background Art
[0002] During the deep hole blasting process, the emulsion explosive roll needs to be loaded into the blast hole. The commonly used tool at present is an L-shaped hook made of a simple steel bar. When loading, the horizontal edge of the hook is used to pierce the plastic film packaging on the upper end of the roll, and the horizontal edge is inserted into the roll. The roll is hooked up and placed into the blast hole. During the process of placing the roll into the blast hole, if too little plastic film is hooked, the plastic film is easy to break, and the roll will detach from the hook in advance and fall into the blast hole in a free fall manner; if too much plastic film is hooked, the roll needs to be manually lifted up to a certain height, and then allowed to fall freely into the blast hole.
[0003] In the above-mentioned method of loading the emulsion explosive roll into the blast hole, the roll falls into the blast hole at a certain speed, which brings safety hazards. Therefore, we propose an emulsion explosive roll clamp to solve the above problem. Utility Model Content
[0004] The purpose of the utility model is to provide a powder roll clamp for emulsion explosives to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A powder roll clamp for emulsion explosives includes a first electric push rod and two vertical plates. A group of protective springs are fixedly installed on the side surfaces of the two vertical plates that are close to each other. An annular clamp is fixedly installed on the end of the two groups of protective springs that are close to each other. The outer surface of each annular clamp is provided with a first strip opening. The inner wall of each annular clamp is fixedly provided with a protective pad, and the inner wall of each protective pad is provided with a second strip opening.
[0007] In a further embodiment, a handle and a controller are fixedly mounted on the upper surface of the first electric push rod, and the controller is electrically connected to the first electric push rod via a wire.
[0008] In a further embodiment, a horizontal plate is fixedly mounted on the output end of the first electric push rod, a vertical block is fixedly mounted on the bottom surface of the horizontal plate, and two square limiting openings are provided on the left side of the vertical block.
[0009] In a further embodiment, a limiting plate is fixedly mounted on a side surface of the two vertical plates that are close to each other, and an outer surface of each limiting plate is slidably connected to an inner wall of the square limiting opening.
[0010] In a further embodiment, a second electric push rod is fixedly mounted on the left side and the right side of the horizontal plate, and an output end of each second electric push rod is fixedly mounted on the outer surface of the vertical plate.
[0011] In a further embodiment, each of the second electric push rods is electrically connected to the controller via a wire, and the inner wall of each of the protective pads is provided with anti-slip grooves.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] The device uses two sets of protection springs to connect two vertical plates with two annular clamps respectively, so that after the two annular clamps clamp the emulsion explosive roll, the two sets of protection springs can prevent the emulsion explosive roll from being subjected to increased clamping force. By installing a protection pad on the inner wall of each annular clamp and providing anti-slip grooves on the inner wall of the protection pad, not only can the emulsion explosive roll be protected, but also the emulsion explosive roll can be prevented from sliding when clamped.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-4 In the utility model, a powder roll clamp for emulsion explosives includes a first electric push rod 7 and two vertical plates 3. A group of protective springs 1 are fixedly installed on the side surfaces of the two vertical plates 3 close to each other. An annular clamp 12 is fixedly installed on the ends of the two groups of protective springs 1 close to each other. The outer surface of each annular clamp 12 is provided with a first strip opening 11, and the inner wall of each annular clamp 12 is fixedly provided with a protective pad 2. The inner wall of each protective pad 2 is provided with a second strip opening 10. The two vertical plates 3 respectively limit the two annular clamps 12. The movement of each vertical plate 3 can drive the annular clamp 12 to adjust its position. The two annular clamps 12 can jointly clamp the powder roll of emulsion explosives. The two protective pads 2 can effectively provide protection for the powder roll of emulsion explosives.
[0023] A handle 6 and a controller 13 are fixedly mounted on the upper surface of the first electric push rod 7. The controller 13 is electrically connected to the first electric push rod 7 through a wire. The staff can move the device by holding the handle 6. The staff can control the extension and retraction of the output end of the first electric push rod 7 through the controller 13. A horizontal plate 5 is fixedly mounted on the output end of the first electric push rod 7. A vertical block 8 is fixedly mounted on the bottom surface of the horizontal plate 5. Two square limit openings 14 are provided on the left side of the vertical block 8. The extension of the output end of the first electric push rod 7 can drive the horizontal plate 5 to move, and the movement of the horizontal plate 5 can drive the vertical block 8 to move.
[0024] The two vertical plates 3 are fixedly installed on the side where they are close to each other. The outer surface of each limit plate 4 is slidably connected to the inner wall of the square limit opening 14. By sliding the outer surfaces of the two limit plates 4 with the inner walls of the two square limit openings 14, the two vertical plates 3 can move smoothly left and right. The left side and the right side of the horizontal plate 5 are fixedly installed with a second electric push rod 9. The output end of each second electric push rod 9 is fixedly installed with the outer surface of the vertical plate 3. The extension and contraction of the output end of each second electric push rod 9 can drive the vertical plate 3 moves, and the limiting plate 4 cooperates with the square limiting opening 14 to ensure that the vertical plate 3 can remain stable when moving. Each second electric push rod 9 is electrically connected to the controller 13 through a wire. The inner wall of each protective pad 2 is provided with anti-slip grooves. By using a wire to electrically connect the two second electric push rods 9 to the controller 13, the operator can control the extension and retraction of the output ends of the two second electric push rods 9 through the controller 13, and then adjust the position of the two annular clamps 12, so that emulsion explosive rolls of different sizes can be tightly clamped.
[0025] The working principle of this utility model is:
[0026] First, the staff controls the output ends of the two second electric push rods 9 to retract through the controller 13. The contraction of the output end of each second electric push rod 9 drives the vertical plate 3 to move. The movement of each vertical plate 3 drives the limit plate 4 to slide in the square limit opening 14 and drives the two protection springs 1 to move. The movement of each group of protection springs 1 drives the annular clamp 12 to move. When the protective pads 2 installed on the inner walls of the two annular clamps 12 tightly clamp the emulsion explosive roll, the staff holds the handle 6 and moves the device to the top of the blast hole. Then the staff controls the output end of the first electric push rod 7 to extend through the controller 13.
