Description

Technical Field

[0001] The utility model belongs to the field of clamping equipment, in particular to a detonating bomb clamping device. Background Art

[0002] Open-pit mines are usually mined using drilling and blasting techniques. The process includes drilling blastholes, filling them with powder, and placing explosive bombs. The explosive bombs are connected to detonators, and the wire at the tail of the detonator serves as the detonation control wire. Due to the large area of ​​open-pit mines, a large number of detonation points need to be arranged during the mining process.

[0003] In the prior art, after the drilling of the blasthole is completed, the explosive bombs and detonators are generally carried to each blasthole for installation by humans. However, the open-pit mine has a large area, a large number of blastholes, and a relatively harsh environment, so mechanized operations are gradually carried out. In the mechanized operation, the mechanical device needs to complete the steps of grabbing the explosive bomb, loading the detonator into the explosive bomb, and placing the explosive bomb and detonator into the blasthole. In the process of loading the detonator into the explosive bomb, the hole on the explosive bomb needs to be aligned with the detonator threading mechanism, but when the clamping device clamps the explosive bomb, the hole position on the explosive bomb is uncertain. Therefore, after the clamping device clamps the explosive bomb to the threading mechanism, under the premise of maintaining the clamping state, the explosive bomb needs to be able to rotate around its own axis so that the hole position on the explosive bomb is aligned with the threading mechanism. However, after the clamping device in the prior art is clamped, the explosive bomb cannot rotate around its own axis. Utility Model Content

[0024] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0025] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0026] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0027] For this example, please refer to Figure 1-4 The utility model provides an embodiment of a detonating bomb clamping device, which is arranged at the end of a mechanical arm for clamping a detonating bomb, and includes a tensioning mechanism 42 and a clamping claw 43; the tensioning mechanism 42 is fixedly arranged at the end of the mechanical arm, and two clamping claws 43 are symmetrically connected to the tensioning mechanism 42, and the clamping degree is controlled by the tensioning mechanism 42; an arc-shaped clamping area 430 is arranged on the clamping claw 43, and a plurality of rollers 431 are arranged inside the clamping area 430. After the two clamping claws 43 are closed and clamped to clamp the detonating bomb, the detonating bomb can rotate along its own axis.

[0028] Open-pit mine blasting has the characteristics of a large area and a large amount of engineering work, so mechanized operation is very necessary. During the operation, it is necessary to install the detonator on the explosive bomb and put the whole thing into the blast hole. Specifically, Figure 2As shown, there are two axially penetrating holes 440 on the explosive bomb 44. The detonator (the detonator is a hard column) is penetrated through one of the holes into the explosive bomb, and then the detonator is reversely inserted into the other hole at the other end of the explosive bomb, and then the detonator leg wire is tightened, so that the explosive bomb can be lifted up through the leg wire and lowered into the blast hole. In the above process, the clamping of the explosive bomb and the installation of the detonator are completed by mechanized operations. In this process, the detonator needs to be aligned with the hole of the explosive bomb, but in order to simplify the design of the mechanical arm, the mechanical arm can only ensure that the explosive bomb is clamped, but cannot ensure the angle of the hole on the explosive bomb after clamping. Therefore, when installing the detonator for the explosive bomb, the explosive bomb needs to be rotated so that the hole on the explosive bomb is aligned with the detonator provided by another mechanical device. This requires that the angle can be rotated and adjusted while keeping the explosive bomb clamped. The clamping device in this embodiment achieves the above effect.

[0029] Furthermore, the tensioning mechanism 42 is two sets of drive cylinders 420 arranged back to back, and the telescopic rods on the other side of the two sets of drive cylinders 420 are each connected to a clamping claw 43. The drive cylinder 420 is an electric cylinder, a hydraulic cylinder or a pneumatic cylinder. When the telescopic rods are retracted, the two clamping claws 43 are also retracted to each other, thereby clamping the explosive bomb. Specifically, when the clamping claws 43 are clamped, the two clamping claws 43 move in a translational manner instead of rotating, which allows multiple clamping positions to be set on the same explosive bomb clamping device, and the clamping stroke and force of each clamping position are consistent, which is not achievable with traditional rotary or scissor-type clamping mechanisms.

[0030] This embodiment can be found in Figure 3 , protruding strips 432 are provided at both ends of the clamping area 430, and both ends of the roller 431 are respectively connected to the protruding strips 432 on both sides, and the outer circumference of the roller 431 exceeds the height of the protruding strips 432 toward the clamping area 430. The outer circumference of the roller 431 is higher than the protruding strips 432. When the clamp 43 clamps the explosive bomb, the roller 431 contacts the explosive bomb, while the protruding strips 432 do not contact the explosive bomb. In this way, after the clamp 43 clamps the explosive bomb, the explosive bomb cannot be axially withdrawn, but can be rotated around the axis, thereby adjusting the position of the hole 440 on the explosive bomb so as to align with the detonator and other mechanical devices used to insert the explosive bomb.

[0031] Furthermore, the rollers 431 of the clamping area 430 are arranged continuously. This ensures that when clamping the explosive bomb, multiple rollers 431 are in contact with the explosive bomb at the same time, which ensures the firmness of the clamping and reduces the squeezing force of each roller 431 on the explosive bomb, so that the force on the explosive bomb is more balanced and prevents over-squeezing.

[0032] This embodiment can be found in Figure 1-4, two clamping areas 430 are arranged on the clamping jaw 43. Because the device adopts a counter-moving loosening mechanism instead of a rotating clamping mechanism, it is feasible to set any number of clamping areas 430, and the clamping force and loosening state of each clamping area are consistent, which can improve the working efficiency and ensure the clamping safety.

[0033] This embodiment can be found in Figure 3 and Figure 4 The back side of the clamping jaw 43 is provided with a transverse reinforcing rib 433 perpendicular to the roller 431. There are two transverse reinforcing ribs 433, which are close to the two side ends of the roller 431, and vertical reinforcing ribs 434 are also provided in the middle of the two clamping areas 430, and the two ends of the vertical reinforcing ribs 434 are connected to the transverse reinforcing ribs 433.

[0034] In the above embodiment, the reinforcing ribs can strengthen the structural strength of the clamping claw 43. Combined with the special tightening method of the device, a large number of clamping areas 430 can be set on a detonating bomb clamping device. The more clamping areas 430 are set, the longer the cantilever is, and the greater the required strength is. The transverse reinforcing ribs 433 and the vertical reinforcing ribs 434 can make up for the strength requirements caused by the increase in the number of clamping areas 430. It should be noted that the reinforcing rib setting method in this embodiment is not the only one. In specific implementation, it can be designed based on the principle of this embodiment in combination with the actual number of clamping areas 430.

[0035] This embodiment can be found in Figure 3 and Figure 4 The clamping area 430 is provided with a through window 4301. The window 4301 can reduce the material usage of the clamping jaw 43 and reduce the weight, especially in a scene with multiple clamping areas 430, it can reduce the end pressure of the robot arm and reduce the design difficulty of the robot arm.

[0036] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
