Description

Technical Field

[0001] This utility model relates to the field of blasting, specifically to a blasting charge basket. Background Technology

[0002] In mining, tunnel construction, and other fields, manual charging allows for real-time adjustment of parameters such as charge quantity and plug length to adapt to changing working conditions. Existing manual charging methods can be broadly divided into two types: direct manual charging, where workers use ladders, ropes, or climb rock walls to charge the explosives, which carries a high risk of fall and is inefficient; and charging using a suspended platform or similar device. A search of application number CN201921608734.2 reveals a blasting charging device comprising a charging cartridge, a sealing plug, a first semi-cylinder, a second semi-cylinder, several explosive tubes, and a detonating cord. The charging cartridge has an open-top cavity. The inner wall of the first semi-cylinder is provided with several pairs of spaced-apart first spacer rings, and the inner wall of the second semi-cylinder is provided with several pairs of corresponding second spacer rings. The first and second semi-cylinders are spliced ​​together to form a complete cylinder and placed into the receiving cavity, with the first and second spacer rings aligned one by one. The explosive tube is placed inside the first and second semi-cylinders and sandwiched between the paired first and second spacer rings. The explosive tube is wrapped by the first and second semi-cylinders, and the first and second spacer rings of the explosive tube are used to separate and precisely limit its position, improving the explosion accuracy and avoiding positional errors during blasting installation. However, the above description still has the following defects in actual use: the existing high-altitude work basket cannot be mounted on compact gantry equipment, cannot further increase the number of personnel loading explosives during blasting, and is prone to affecting the normal operation of other working parts, lacking safety. Therefore, it is necessary to design a practical explosive loading basket for blasting. Utility Model Content

[0003] The purpose of this utility model is to provide a charging basket for blasting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a blasting charge basket, comprising: a portal frame, one end of which is provided with two multi-stage hydraulic lifting support columns, the top of each of the two multi-stage hydraulic lifting support columns is provided with a rotating platform, and the top of each of the two rotating platforms is fixedly connected with a rotating column;

[0005] A first telescopic boom, comprising a first boom hinged to the top surface of a slewing column, a drive cylinder mounted on one end of the first boom via a fixing member, the output rod of the drive cylinder being fixedly connected to the surface of a horizontal telescopic arm at one end of the first boom via a connecting member, the bottom of the first boom being hinged to one end of the telescopic cylinder, and the output rod of the telescopic cylinder being hinged to the bottom surface of the slewing column.

[0006] The suspended basket body has a hinge at its top, and the top of the hinge is rigidly connected to one end of the horizontal telescopic arm output rod. The suspended basket body also has casters at its bottom and front.

[0007] As a preferred embodiment of this utility model: the rotary platform is made of high-strength material, and the rotary column is made of a fixed column and a fixed steel plate. The fixed steel plate is hinged to the output rod of the first boom and the pitch cylinder respectively.

[0008] As a preferred embodiment of the present invention: the top of the gantry frame is provided with two slide rails, the inner walls of the two slide rails are slidably connected with drive seats, one side of the two drive seats is provided with a movable seat, the other side of the two movable seats is provided with a second tilting telescopic boom, and the other end of the second tilting telescopic boom is provided with an auxiliary basket.

[0009] As a preferred embodiment of this utility model: the initial height of the top of both rotary columns is flush with the height of one end of the gantry frame.

[0010] As a preferred embodiment of this utility model, the two slide rails and the two multi-stage hydraulic lifting support columns are on the same straight line.

[0011] As a preferred embodiment of this utility model: the multi-stage hydraulic lifting support column is equipped with a vertical multi-stage hydraulic cylinder inside, and the output rod of the vertical multi-stage hydraulic cylinder is fixedly connected to the bottom of the rotating platform.

[0012] As a preferred embodiment of this utility model, the inner wall of the suspended basket is provided with a detachable reinforced guardrail around its perimeter.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The two rotating platforms are lifted and lowered by the vertical multi-stage hydraulic cylinders inside the two multi-stage hydraulic lifting support columns. The two rotating platforms, together with the two rotating columns, drive the two first tilting telescopic booms to move. The two first tilting telescopic booms drive the two basket bodies to move, thereby adjusting the height of the loading. At the same time, the two multi-stage hydraulic lifting support columns, together with the internal structure, drive the two rotating platforms to return to the initial state. When other working arms are working, the basket bodies are prevented from interfering with each other. The two rotating platforms drive the two rotating columns to rotate, which can prevent collisions and interference between the booms. At the same time, the two first tilting telescopic boom structures can be retracted and stored at the front end of the portal frame, improving the flexibility of the loading basket when it is used.

[0015] (2) The two rotating platforms are driven to rise and fall by the vertical multi-stage hydraulic cylinders inside the two multi-stage hydraulic lifting support columns. The two rotating platforms, together with the two rotating columns, drive the two first tilting telescopic booms to move. The output rods of the two drive cylinders, together with the connecting parts, drive the horizontal telescopic booms inside the two first booms to move. The two horizontal telescopic booms, together with the hinge parts, drive the two basket bodies to move, thereby bridging the distance between the basket body and the working surface. At the same time, the two tilting cylinders drive the two output rods to move, thereby slowly supporting the first boom at an angle, thereby further expanding the lifting range of the basket and increasing the structural stability. As the lifting range of the basket body increases, the size of the output rod of the first boom needs to be reduced to ensure the stability of the overall structure and avoid injury to the operators.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-4 A blasting charge basket includes: a gantry frame 1, with two multi-stage hydraulic lifting support columns 2 at one end of the gantry frame 1, a rotating platform 3 at the top of each of the two multi-stage hydraulic lifting support columns 2, and a rotating column 31 fixedly connected to the top of each of the two rotating platforms 3.

[0023] Please see Figure 1 The first telescopic boom 4 includes a first boom 41 hinged to the top surface of the slewing column 31. A drive cylinder 42 is fixedly mounted on the surface of one end of the first boom 41 by a fastener. The output rod of the drive cylinder 42 is fixedly connected to the surface of the horizontal telescopic arm 43 at one end of the first boom 41 by a connector. The bottom of the first boom 41 is hinged to one end of the telescopic cylinder 44. The output rod of the telescopic cylinder 44 is hinged to the surface of the bottom end of the slewing column 31.

[0024] In practical use: The vertical multi-stage hydraulic cylinders 21 inside the two multi-stage hydraulic lifting support columns 2 drive the two rotating platforms 3 to lift and lower. The two rotating platforms 3, together with the two rotating columns 31, drive the two first tilting telescopic booms 4 to move. The output rods of the two drive cylinders 42, together with the connecting parts, drive the horizontal telescopic booms 43 inside the two first booms 41 to move. The two horizontal telescopic booms 43, together with the hinges 51, drive the two basket bodies 5 to move, thereby bridging the distance between the basket body 5 and the working surface. At the same time, the two tilting cylinders 44 drive the two output rods to move, thereby slowly providing oblique support to the first booms 41, thereby further expanding the lifting range of the basket and increasing structural stability. As the lifting range of the basket body 5 increases, the size of the output rods of the first booms 41 needs to be reduced to ensure the stability of the overall structure and avoid injury to the operators.

[0025] Please see Figure 1 The suspended basket body 5 has a hinge 51 on its top, and the top of the hinge 51 is rigidly connected to one end of the output rod of the horizontal telescopic arm 43. The bottom and front of the suspended basket body 5 are equipped with casters 52.

[0026] In practical use: the hinge 51 at the top of the suspended platform body 5 is inductively connected to one end of the horizontal telescopic arm 43, thereby increasing the stability of the suspended platform after installation. At the same time, the casters 52 on the front and bottom of the suspended platform body 5 facilitate easy disassembly and transportation.

[0027] Please see Figure 2 The slewing platform 3 is made of high-strength material. The slewing column 31 is made of a fixed column 3101 and a fixed steel plate 3102. The fixed steel plate 3102 is hinged to the output rods of the first boom 41 and the pitch cylinder 44 respectively.

[0028] In practical use: when the rotary platform 3 rotates, it drives the fixed column 3101 and the fixed steel plate 3102 to rotate. The fixed steel plate 3102 drives the first boom 41 and the pitch cylinder 44, which are hinged to it, to rotate, thereby avoiding interference between the structures of the first pitch telescopic boom 4.

[0029] Please see Figure 1 The top of the gantry frame 1 is provided with two slide rails 11, and the inner walls of the two slide rails 11 are slidably connected with drive seats. One side of each drive seat is provided with a movable seat, and the other side of each movable seat is provided with a second tilting telescopic boom 12. The other end of the second tilting telescopic boom 12 is provided with an auxiliary basket 13.

[0030] In practical use: the two drive seats drive the two movable seats to slide on the surface of the two slide rails 11 at the top of the gantry frame 1. The two movable seats, together with the structure of the two second telescopic booms 12, adjust the position of the two auxiliary baskets 13, thereby facilitating the flexible coordination when using the loading basket.

[0031] Please see Figure 2 The initial height of the top of the two rotating columns 31 is level with the height of one end of the portal frame 1.

[0032] In practical use: the initial height of the top of the two slewing columns 31 is level with the height of one end of the gantry frame 1, so that the two basket bodies 5 can be removed when not in use, and the structure of the two first tilting telescopic booms 4 can be stored to avoid affecting the operation of other working arms driving the auxiliary basket 13.

[0033] Please see Figure 2 The two slide rails 11 and the two multi-stage hydraulic lifting support columns 2 are on the same straight line.

[0034] In practical use: the two multi-stage hydraulic lifting support columns 2 and the two slide rails 11 are on the same straight line, which facilitates stable installation between the device structures and avoids the occurrence of gravity shift during adjustment and storage, which may cause instability in the overall structure.

[0035] Please see Figure 1The multi-stage hydraulic lifting support column 2 is equipped with a vertical multi-stage hydraulic cylinder 21 inside, and the output rod of the vertical multi-stage hydraulic cylinder 21 is fixedly connected to the bottom of the rotary platform 3.

[0036] In practical use: the output rod of the vertical multi-stage hydraulic cylinder 21 inside the multi-stage hydraulic lifting support column 2 drives the rotary platform 3 to move, thereby facilitating the adjustment of its position and height.

[0037] Please see Figure 1 The inner walls of the suspended platform body 5 are equipped with detachable reinforced guardrails 53.

[0038] In practical use: The removable reinforced guardrails 53 around the inner wall of the basket body 5 facilitate the safety of personnel loading medicines during the loading process.

[0039] In use, the vertical multi-stage hydraulic cylinders 21 inside the two multi-stage hydraulic lifting support columns 2 drive the two rotating platforms 3 to lift and lower. The two rotating platforms 3, together with the two rotating columns 31, drive the two first tilting telescopic booms 4 to move. The output rods of the two drive cylinders 42, together with the connecting parts, drive the horizontal telescopic arms 43 inside the two first booms 41 to move. The two horizontal telescopic arms 43, together with the hinges 51, drive the two basket bodies 5 to move, thereby bridging the distance between the basket body 5 and the working surface. At the same time, the two tilting cylinders 44 drive the two output rods to move, providing slow oblique support to the first booms 41, further expanding the lifting range of the basket and increasing structural stability. As the lifting range of the basket body 5 increases, the size of the output rods of the first booms 41 needs to be reduced to ensure the stability of the overall structure and avoid injury to the operators.
