Description

Technical Field

[0001] The utility model relates to the technical field of explosion isolation for emulsion explosive transportation, in particular to an explosion isolation device for belt transportation of plastic film large-diameter cartridges of colloidal emulsion explosive. Background Technique

[0002] Emulsion explosive is a kind of oil-in-water emulsion explosive formed by evenly dispersing micro-droplets of oxidizer salt aqueous solution in an oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres with the help of an emulsifier. After the production of emulsion explosive, it needs to be transported, usually by belt. However, to ensure safety during transportation, a safe distance is generally required between emulsion explosives. Currently, relays and telescopic cylinders are used to drive the gate to continuously operate and block, but this is inconvenient to use, costly, time-consuming for later maintenance, and relying solely on the gate is likely to squeeze the emulsion explosive, resulting in transportation blockage, and its use has limitations. Content of the Utility Model

[0003] The purpose of the utility model is to provide an explosion isolation device for belt transportation of plastic film large-diameter cartridges of colloidal emulsion explosive to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an explosion isolation device for belt transportation of plastic film large-diameter cartridges of colloidal emulsion explosive, including symmetrically arranged brackets. A conveyor belt is drivingly connected inside the brackets, and a driving motor is fixedly connected to one side of the brackets through a support plate. The output end of the driving motor is drivingly connected to the conveyor belt. An installation frame is fixedly connected to the upper end of the brackets. Support blocks are fixedly connected to the inner walls of the installation frame near the bottom end, and symmetrically arranged sliding grooves are formed in the inner walls on both sides of the installation frame. Sliding plates are slidably connected in the sliding grooves. A rack plate is fixedly connected to the opposite sides of the sliding plates. Symmetrically arranged columns are fixedly connected to the lower end of the rack plate. Gates arranged at a reverse 45° angle are fixedly connected to the lower ends of the columns. A blocking strip is fixedly connected to the upper end of the gates. A stepping motor is fixedly connected to the inner wall of the installation frame far from the sliding grooves. The output end of the stepping motor is fixedly connected to a rotating rod through a self-locking coupling. A half gear is fixedly connected to the side of the rotating rod far from the stepping motor. The half gear is meshingly connected to the rack plate.

[0005] Preferably, symmetrically arranged mounting rods are fixedly connected to both sides of the bottom end of the gates. A connecting rod is rotatably connected to the opposite sides of the mounting rods through bearings. A soft sleeve is fixedly sleeved on the connecting rod.

[0006] Preferably, auxiliary rods are fixedly connected to both sides of the sliding plates and the gates together.

[0007] Preferably, symmetrically arranged supporting feet are fixedly connected to both sides of the lower end of the bracket.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: by continuously rotating the stepper motor and the half gear, and cooperating with the chute and the slide rod to drive the rack plate to continuously rise and fall, a timing gate is formed to fall regularly. Moreover, the structure is simple, the cost is low, and it is convenient to replace in the later stage. And when the gate descends, the rotating connecting rod and the soft sleeve arranged at the front end will block the emulsion explosive in advance, avoiding blockage caused by the downward pressure of the gate during its descent and affecting the subsequent continuous transmission.

Detailed Embodiments

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-5The utility model provides a technical solution: a belt conveyor explosion-proof device for large-diameter plastic film rolls of colloidal emulsion explosives, comprising a symmetrically arranged bracket 1, a conveyor belt 2 is connected to the bracket 1 internally, and a driving motor 3 is fixedly connected to one side of the bracket 1 through a supporting plate, and the output end of the driving motor 3 is connected to the conveyor belt 2 by driving, and a mounting frame 4 is fixedly connected to the upper end of the bracket 1, and a supporting block 5 is fixedly connected to the inner wall of the mounting frame 4 near the bottom end, and symmetrically arranged slide grooves 6 are opened on the inner walls of both sides of the mounting frame 4, and slide plates 7 are slidably connected in the slide grooves 6, and a rack plate 8 is fixedly connected to the opposite side of the slide plate 7, and the lower end of the rack plate 8 is fixedly connected to the rack plate 8. The support 9 is called a support, and the lower end of the support 9 is fixedly connected to a gate 10 set at an angle of 45° inversely, and the upper end of the gate 10 is fixedly connected to a blocking bar 12, and the inner wall of the mounting frame 4 away from the slide slot 6 is fixedly connected to a stepper motor 16, and the output end of the stepper motor 16 is fixedly connected to a rotating rod 17 through a self-locking coupling, and the side of the rotating rod 17 away from the stepper motor 16 is fixedly connected to a half gear 18, and the half gear 18 is meshingly connected to the rack plate 8; symmetrically arranged mounting rods 13 are fixedly connected on both sides of the bottom end of the gate 10, and the mounting rods 13 are connected to a connecting rod 14 that rotates together with the opposite side through a bearing, and the connecting rod 14 is fixedly sleeved with a soft sleeve 15.

[0017] Auxiliary rods 11 are fixedly connected to both sides of the slide plate 7 and the gate 10 , which is beneficial to increase the connection stability between the slide plate 7 and the gate 10 through the auxiliary rods 11 .

[0018] Both sides of the lower end of the bracket 1 are fixedly connected with symmetrically arranged supporting feet 19 , which is beneficial to increase the overall supporting stability of the bracket 1 through the supporting feet 19 .

[0019] Specifically, when the utility model is used, when it is necessary to transport the gel emulsion explosive, the drive motor 3 and the stepper motor 16 are respectively started by an external power supply, and the output end of the drive motor 3 drives the conveyor belt 2 inside the bracket 1 to rotate. At this time, the packaged gel emulsion explosive is sequentially transported to the upper end of the conveyor belt 2. At this time, the output end of the stepper motor 16 drives the half gear 18 to rotate through the self-locking coupling, and the output end of the half gear 18 meshes and drives the rack plate 8. The rack plate 8 is meshed with the rotation of the half gear 18 and stably drives the rack plate 8 to rise. When the tooth block on the rack plate 8 and the half gear 18 are engaged, the rack plate 8 is stably driven to rise. When the gear 18 loses engagement, the rack plate 8 will steadily descend under the sliding limit of the slide groove 6 and the slide plate 7. At this time, the rack plate 8 will drive the gate 10 to descend in stages through the support 9 and the auxiliary rod 11. When the gate 10 descends, it will abut against the support block 5 to avoid complete contact with the conveyor belt 2. At the same time, when the gate 10 descends, the soft sleeve 15 is driven to descend and abut against the conveyor belt 2 through the installation rod 13 and the connecting rod 14. At this time, the rotatable connecting rod 14 and the soft sleeve 15 will separate the emulsion explosive in advance to avoid the explosives from being too close to each other, thereby increasing the overall safety isolation of the emulsion explosive transportation.
