Description

Technical Field

[0001] The invention relates to the field of grain storage and the technical field of emergency rescue of safety accidents, and in particular to an emergency rescue system. Background Art

[0002] Grain is stored in the form of grain piles in the warehouse. During the storage process, due to the influence of various factors such as temperature and humidity, moisture, pests and impurities, the following things may happen during the storage and grain in and out operations, which require emergency treatment:

[0003] First, during the grain in and out operation, there may be an accident of people being buried in the grain pile, and emergency rescue operations need to be carried out on the grain surface. Grain burying accidents often occur in grain storage enterprises. After a certain period of storage, grain will be discharged when it is discharged, and the grain pile will be retained, such as arches, hanging walls, and tops, which will affect the normal grain discharge operation. If there is improper protection or illegal operations during the grain in and out operation such as the removal of the retained grain pile, an accident of people being buried in the grain pile will occur. Once a person is buried in the grain, emergency rescue is required on the grain surface. Because the height difference of the grain pile produces pressure and friction on the human body, directly dragging the buried person may tear it to pieces or exceed the pressure that the body can withstand, causing injury. In order to enable people to breathe during emergency rescue, the grain around the human body must be removed as soon as possible. Due to the limitations of the space in the warehouse, the access channel, and the special working environment of the grain surface, the existing mechanical equipment cannot reach the grain surface and is not suitable for emergency operations on the grain pile. Basically, emergency operations are carried out by manual digging of grain, which is labor-intensive and inefficient, resulting in poor emergency rescue results.

[0004] Because the grain pile is a kind of loose granular body, it has both the difficult-to-compress property of a solid and the partial flow property of a fluid. After the grain around the buried person is removed, there will be grain backflow. In order to quickly remove the grain around the buried person, it is necessary to insert a grain blocking plate into the grain pile to block the backflowing grain, that is, a grain blocking wall must be formed around the human body before the grain can be quickly dug out. After testing, it was found that due to the solid properties, internal pressure and friction of the grain pile, it is difficult to insert the grain blocking plate into the grain pile (especially the rice pile) to a certain depth.

[0005] In addition, during the grain storage process, the grain pile may sometimes become hot locally, and emergency measures must be taken to dig the hot grain out from the middle of the grain pile.

[0006] At present, there is little research on grain and surface emergency rescue methods and equipment, and there is basically no applicable emergency rescue equipment. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0031] like Figure 1 As shown, an emergency rescue system provided by this embodiment includes a driving device 1, a digging and conveying device 2, a support assembly 3 and a step-type support system 4. The step-type support system 4 is inserted into the grain surface 5 at the location where rescue is required. The driving device 1, the digging and conveying device 2, the support assembly 3 and the step-type support system 4 are split structures, which can be detachably connected, so that they can be manually transported to the grain surface 5 in an emergency and quickly assembled on site.

[0032] like Figure 2 As shown, the driving device 1 comprises a driving source 11, a transmission system 12 and a quick fastening device 13. The driving source 11 is a driving motor.

[0033] The excavating and conveying device 2 includes an excavating component 21, a conveying section 22 and a head component 23. The head component 23 includes a housing 232 and a rotating shaft 231 disposed in the housing 232 and connected to the driving device 1. The rotating shaft 232 is driven and connected to the driving source 11 through a transmission system 12. The driving device 1 is installed on the housing 232 through the quick fastening device 13. The quick fastening device 13 is two L-shaped structural plates welded on the housing 232. The two L-shaped structural plates are arranged relative to each other to form a slide groove. The bottom of the driving source 11 is plugged into the slide groove and fixed by bolts, thereby achieving the purpose of quick fastening. The housing 232 is provided with a grain inlet 233 and a grain outlet 234. The grain inlet 233 is disposed on the vertical side wall of the housing 232, and the grain outlet 234 is located at the bottom of the housing 232 and above the grain surface 5.

[0034] The conveying section 22 includes a conveying spiral ring sheet 222 and a pipeline 221. The pipeline 221 is connected to the grain inlet pipe port 233 of the casing 232, and the pipeline 221 and the casing 232 are detachably connected via a clamp.

[0035] The scooping assembly 21 includes a barrel 211, a main shaft 212, a grain-taking spiral blade 213 and a main shaft support seat 214. The barrel 211 is detachably connected to an end of the pipe 211 away from the grain inlet 233 through a clamp 223. The grain-taking spiral blade 213 is arranged around the outer circumference of the main shaft 212, and the main shaft 212 is supported in the barrel 211 through the main shaft support seat 214.

[0036] like Figure 2 , 3 As shown, the spindle support seat 214 is a disc structure, the middle of which is connected to the spindle 212 through a bearing, and one side edge of the spindle support seat 214 is fixed to the inner wall of the cylinder 211. In order to ensure the stability of the positioning of the spindle 212, the number of the spindle support seats 214 is two, which are arranged at intervals on the spindle 212 to form two-point positioning.

[0037] like Figure 2 As shown, the conveying spiral ring piece 222 is arranged in the pipe 221, and one end of the conveying spiral ring piece 222 is connected to the rotating shaft 231, and the other end extends to the cylinder 211 outside the pipe 221 and is connected to the main shaft 212. The grain taking spiral blade 213 extends to the outside of the cylinder 211 together with the main shaft 212.

[0038] In the actual design structure, the grain-taking spiral blade 213 is a segmented structure on the main shaft 212 and needs to avoid the connection position between the main shaft 212 and the main shaft support seat 214.

[0039] The main shaft 212 can position the conveying spiral ring piece 222 in the axial and diameter directions, and can also be used to fix the grain taking spiral blade 212 to form a conical spiral head structure, and rotate together with the grain taking spiral blade 212 during operation, so that the grain is sucked into the cylinder 211. At the same time, the main shaft 212 can also cause the digging component 21 to move into the grain pile.

[0040] The side wall of the cylinder 211 is provided with a plurality of slots 215 communicating with the inner cavity of the cylinder 211. The excavated grain can enter from the slots 215 in addition to the lower port of the cylinder 211. The pipeline 221 and the conveying spiral ring piece 222 are flexible structures. The conveying spiral ring piece 222 is a spring-shaped structure, which also has a certain elasticity and can well adapt to the multi-directional and variable depth excavation and conveying of grain on the grain surface.

[0041] The support assembly 3 includes a platform 31 and a plurality of legs 32 hinged to the platform 31, and the number of the legs 32 can be three or more. A plate 33 is provided at the upper end of the platform, and a through hole is opened on the plate 33, and a bottom fixing member 235 is inserted into the through hole to achieve a detachable connection. After the bottom fixing member 235 is inserted into the plate 33, the driving device 1 is supported at a certain height above the grain surface 5.

[0042] In actual use, the number of the support assembly 3 can also be set to two or more, supported at the middle part of the excavation and conveying device 2, so as to facilitate the excavation operation at the end after the excavation and conveying device 2 is lifted (such as Figure 1 as shown).

[0043] The plurality of legs 32 can be retracted and extended by a hinged connecting rod 34 provided in the middle. The hinged connecting rod 34 is a foldable connecting rod mechanism, which is hinged to the legs 32. The legs 32 are opened and fixed by unfolding the hinged connecting rod 34. The structural principle is similar to that of an umbrella frame. A horizontal plate 35 is fixedly provided on the outside of each leg 32. The function of the horizontal plate 35 is to be placed above the grain surface to prevent the support assembly 3 from continuing to sink into the grain pile. In addition, the horizontal plate 35 also plays a certain supporting role. A sharp angle structure is provided at the bottom of each leg 32, forming a nail-like structure, which is convenient for quick insertion into the grain pile.

[0044] like Figure 1 , 4 As shown, the step-type support system 4 includes multiple layers of grain-blocking assembly devices with the same structure and different opening diameters. In this embodiment, the step-type support system 4 has two layers, namely, a first-layer grain-blocking assembly device 41 and a second-layer grain-blocking assembly device 42. After installation, the first-layer grain-blocking assembly device 41 is located above the second-layer grain-blocking assembly device 42, and the first-layer opening diameter is the largest, and gradually decreases downwards.

[0045] The first-layer grain blocking assembly device 41 includes a positioning support ring 411, a cylindrical plate 412, a lower support ring 413 and a positioning pin 414. The positioning support ring 411 is arranged at the upper end of the inner wall of the cylindrical plate 412, the lower support ring 413 is arranged at the lower end of the inner wall of the cylindrical plate 412, and the positioning pin 414 horizontally penetrates from the side wall of the cylindrical plate 412 to the outside.

[0046] In order to facilitate the insertion of the cylindrical plate 412 into the grain pile, the cylindrical plate 412 is formed by inserting a plurality of arc plates into the grain pile. The cylindrical plate 412 is provided with a through hole matching the positioning pin 414. In this embodiment, the positioning pin 414 is a U-shaped structure. When in use, the U-shaped opening is inserted into the grain pile.

[0047] The structure of the second-layer grain-blocking assembly device 42 is the same as that of the first-layer grain-blocking assembly device 41 .

[0048] The cylindrical plate 422 of the second-layer grain-blocking assembly 42 is placed inside the cylindrical plate 412 of the first-layer grain-blocking assembly 41, and the upper outer wall of the cylindrical plate 422 of the second-layer grain-blocking assembly 42 is arranged adjacent to the lower support ring 413 of the first-layer grain-blocking assembly 41. In order to facilitate quick and labor-saving insertion into the grain pile, the bottoms of the positioning support rings 411, 421 and the cylindrical plates 412, 422 are all sharp-angle structures.

[0049] The working principle of the emergency rescue system provided by the present invention is:

[0050] The driving device 1, the excavating and conveying device 2, the supporting assembly 3 and the stepped supporting system 4 are stored in four parts; when they are needed, they are installed according to the above structure.

[0051] The legs 32 are opened and placed beside the rescue site, the legs 32 are inserted into the grain pile, and the horizontal plate 35 contacts the grain surface.

[0052] First, install the first layer of grain blocking assembly device 41: press the positioning support ring 411 into the grain surface, and then insert the cylindrical plate 412 into the grain pile close to the outer ring of the positioning support ring 411. Because the height of the cylindrical plate 412 is 20cm~60cm, this short-sized structure makes it easy to insert the cylindrical plate 412 into the grain pile.

[0053] The digging component 21 and part of the pipeline 221 of the digging and conveying device 2 are extended into the step support system 4 and placed around the human body, and the driving source 11 is started. The driving source 11 sequentially drives the rotating shaft 231, the conveying spiral ring piece 222, the main shaft 212 and the grain-taking spiral blade 213 to rotate. Through the rotation of the grain-taking spiral blade 213 and the conveying spiral ring piece 222, the grain around the human body is transferred from the cylinder 211, the pipeline 221, the grain inlet pipe port 233 to the casing 232, and falls from the grain outlet 234.

[0054] After a certain depth is dug, a positioning nail 414 is inserted into the corresponding through hole position on the cylindrical plate 412. The positioning nail 414 is inserted into the grain pile to lift the positioning support ring 411.

[0055] The lower support ring 413 is installed on the inner wall of the lower end of the cylindrical plate 412 to form the first layer of supporting grain retaining plate ring 41. Then, the second layer of positioning support ring 421 is pressed into the grain surface in the first layer of supporting grain retaining plate ring 41, and then the cylindrical plate 422 is close to the outer ring of the positioning support ring 421 and inserted into the grain pile. After a certain depth is dug, the positioning pins 424 are inserted into the corresponding through-hole positions on the cylindrical plate 422. The positioning support ring 421 is lifted up by inserting the positioning pins 424 into the grain pile.

[0056] The lower support ring 423 is installed on the inner wall of the lower end of the cylindrical plate 422 to form a second layer of supporting grain retaining plate ring 42.

[0057] In order to facilitate the lower support ring 423 of the second layer to be placed in the cylindrical plate 412, the structure of the lower support ring 423 can be a segmented structure, such as: two pieces are placed in and installed separately and then assembled.

[0058] If necessary, the above steps can be repeated to sequentially complete the installation of the third-layer grain retaining assembly device or the fourth-layer grain retaining assembly device until the grain in the stepped support system 4 is dug out to achieve the purpose of emergency rescue.

[0059] The step support system 4 adopts a layered step combined support method. After controlling the length and width of the grain support plate, it is easy to insert the cylindrical plate used for grain support into the designated position of the grain pile, and a grain support plate circle can be built in the grain pile in a very short time. The digging and conveying device 2 adopts a multi-unit combined structure. When each unit is separated, it is light in weight, which is convenient for emergency manual transportation to the grain surface.

[0060] A set of driving device 1 and digging and conveying device 2 or multiple sets can be used to dig the grain in the stepped support system 4 at the same point, and the grain around the human body can be rolled into the casing and dropped, so as to realize the rapid transfer of buried grain and meet the needs of emergency rescue.

[0061] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
