Description

Technical Field

[0001] The utility model relates to the technical field of blasting, in particular to an open-air blasthole pipe extraction device. Background Art

[0002] With the development of science and technology, more and more traditional industries have also applied related technologies. In order to facilitate the management of explosive materials and meet the needs of safety in blasting operations, digital electronic detonators are becoming more and more popular.

[0003] The existing Chinese patent with publication number CN110220430A discloses a simple device for clamping an electronic detonator dropped into a blasthole, including a blasthole and an electronic detonator, a remote control operator is arranged on the ground adjacent to the blasthole entrance outside the blasthole, a clamping mechanism is arranged in the blasthole, and a lifting rope is arranged between the remote control operator and the clamping mechanism; the clamping mechanism includes two symmetrical clamping legs, the upper parts of the two clamping legs are connected by hinges, a camera and a lighting lamp are arranged at the lower part of the hinge, the inner sides of the lower parts of the two clamping legs are connected by springs, the lower parts of the two clamping legs are in an open state, and electromagnets are respectively installed on the inner sides of the lower parts of the two clamping legs, and the tension of the springs is less than the attraction generated by the electromagnet after power is turned on; a display screen and an operation button are arranged on the remote control operator, a control module, a motor and a rotating shaft are arranged in the remote control operator, one end of the lifting rope is fixed on the rotating shaft, and the other end of the lifting rope is connected to the top of the clamping mechanism. The utility model is safe and reliable, saving time and effort.

[0004] However, the utility model has the following defects when used specifically:

[0005] In actual use, people often choose to use a simple iron hook to take it out. When the depth of the blasthole is large, the clamping mechanism is not easy to control, which makes it extremely difficult to take out the industrial electronic detonator tube that has fallen into the blasthole. In addition, when the iron clamping mechanism contacts the wall of the blasthole, it is very easy to generate sparks due to friction and collision, causing potential major safety hazards such as premature explosion.

[0006] Since the upper parts of the two clamping legs are connected by a hinge, a camera and a lighting lamp are arranged at the lower part of the hinge, and the inner sides of the lower parts of the two clamping legs are connected by a spring, the lower parts of the two clamping legs are in an open state, and electromagnets are respectively installed on the inner sides of the lower parts of the two clamping legs. The tension of the spring is less than the attraction generated when the electromagnet is energized. Due to the limitation of electricity, the attraction is unstable, resulting in low stability of the device. Utility Model Content

[0007] The utility model aims to provide an open-air blasthole pipe extraction device to solve the problems raised in the above-mentioned background technology.

[0008] In order to achieve the above utility model purpose, the utility model adopts the following technical solutions:

[0009] Provided is an open-air blasthole pipe extraction device, comprising a fixed rod assembly, wherein the lower end of the fixed rod assembly is fixedly connected to three hook body mechanisms, and the three hook body mechanisms are annularly arranged at the lower end of the fixed rod assembly;

[0010] The hook body is made of explosion-proof copper alloy;

[0011] The three hook body mechanisms all include:

[0012] A hook assembly, the upper end of which is fixedly connected to the lower end of the fixed rod assembly;

[0013] And the three hook assemblies are annularly arranged at the lower end of the fixed rod assembly, and one side of the hook assembly is rotatably connected with an elastic anti-slip device assembly.

[0014] As a preferred solution of the utility model, the fixing rod assembly includes:

[0015] A fixed rod body is provided with a connecting platform at the lower end of the fixed rod body, a first hinge block is provided on the connecting platform, and the hook assembly is fixedly connected to the fixed rod body through the first hinge block.

[0016] As a preferred solution of the utility model, the hook assembly includes:

[0017] The hook body has a second hinge block at its upper end, and the hook body is fixedly connected to the first hinge block on the connecting platform through the second hinge block.

[0018] As a preferred solution of the utility model, a receiving groove is provided on the hook body, a connecting hole is provided on the top of the receiving groove, and the elastic anti-slip device assembly is rotatably connected to the hook body through the connecting hole; and

[0019] The hook body is also provided with a notch groove.

[0020] As a preferred solution of the utility model, the elastic anti-slip device assembly includes:

[0021] A cylindrical pin, the cylindrical pin being rotatably mounted in the connecting hole, both ends of the cylindrical pin being fixedly connected with anti-dropping buckles, and positions near both ends of the cylindrical pin being sleeved with torsion springs; and

[0022] One end of the torsion spring is fixedly connected to the cylindrical pin, and the other end of the torsion spring is fixedly installed at the bottom of the storage groove.

[0023] As a preferred solution of the utility model, it is characterized in that:

[0024] The upper and lower ends of the fixing rod body are both provided with heat dissipation cavities.

[0025] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0026] When the electronic detonator needs to be taken out from the blast hole, the upper end of the fixed rod assembly is held and the entire device is inserted into the blast hole. Since the upper end of the hook assembly is rotatably connected to the lower end of the fixed rod assembly, the three hook assemblies are arranged in a ring at the lower end of the fixed rod assembly. Since the hook body mechanism is made of explosion-proof copper alloy, it is not easy to generate sparks when the hook body mechanism rubs against the blast hole, which is safer and more reliable.

[0027] 2. When it is necessary to take out the electronic detonator from the blast hole, hold the upper end of the fixed rod assembly and extend the entire device into the blast hole. Since the upper end of the hook assembly is rotatably connected to the lower end of the fixed rod assembly, three hook assemblies are annularly arranged at the lower end of the fixed rod assembly. One side of the hook assembly is rotatably connected to the elastic anti-slip device assembly. When the detonator leg line enters the hook assembly, the elastic anti-slip device assembly can swing back and forth. Therefore, the elastic anti-slip device assembly and the hook assembly cooperate to prevent the detonator leg line from slipping. Since the hook body mechanism is made of explosion-proof copper alloy, the success rate of taking out the detonator is higher and safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Reference Figure 1-2 As shown, an open-air blasthole pipe extraction device includes a fixed rod assembly 1, the lower end of which is fixedly connected to three hook body mechanisms 2, and the three hook body mechanisms 2 are annularly arranged at the lower end of the fixed rod assembly 1;

[0039] The hook body mechanism 2 is made of explosion-proof copper alloy;

[0040] The three hook body mechanisms 2 each include:

[0041] A hook assembly 21, the upper end of the hook assembly 21 is fixedly connected to the lower end of the fixed rod assembly 1;

[0042] The three hook assemblies 21 are annularly arranged at the lower end of the fixed rod assembly 1 , and one side of the hook assembly 21 is rotatably connected to an elastic anti-slip device assembly 22 .

[0043] When it is necessary to take the electronic detonator out of the blast hole, hold the upper end of the fixed rod assembly 1 and extend the entire device into the blast hole. Since the upper end of the hook assembly 21 is rotatably connected to the lower end of the fixed rod assembly 1, one side of the hook assembly 21 is rotatably connected to the lower end of the pull rod assembly 3. The three hook assemblies 21 are arranged in a ring at the lower end of the fixed rod assembly 1. When the detonator leg line enters the hook assembly 21, the elastic anti-slip device assembly 22 can swing back and forth. Therefore, under the cooperation of the elastic anti-slip device assembly 22 and the hook assembly 21, the detonator leg line can be prevented from slipping. The hook body mechanism 2 is made of explosion-proof copper alloy.

[0044] The fixing rod assembly 1 comprises:

[0045] The fixing rod body 11 has a connecting platform 12 at its lower end, and a first hinge block 13 is provided on the connecting platform 12 . The hook assembly 21 is fixedly connected to the fixing rod body 11 via the first hinge block 13 .

[0046] A connecting platform 12 is provided at the lower end of the fixing rod body 11 , a first hinge block 13 is provided on the connecting platform 12 , and the hook assembly 21 is fixedly connected to the fixing rod body 11 through bolts and the first hinge block 13 .

[0047] Reference Figure 4 As shown, the hook assembly 21 includes:

[0048] The hook body 211 has a second hinge block 212 at its upper end, and the hook body 211 is fixedly connected to the first hinge block 13 on the connecting platform 12 via the second hinge block 212 .

[0049] The first hinge block 13 is fixedly connected to the second hinge block 212 by bolts, so that the connection between the hook body 211 and the fixing rod body 11 is more firm and reliable.

[0050] The hook body 211 is provided with a receiving groove 2111 , the top of the receiving groove 2111 is provided with a connecting hole 2112 , and the elastic anti-dropping device assembly 22 is rotatably connected to the hook body 211 through the connecting hole 2112 ; and

[0051] The hook body 211 is further provided with a notch groove 2113 .

[0052] A storage groove 2111 is provided on the hook body 211, and a connecting hole 2112 is provided on the top of the storage groove 2111. The elastic anti-slip assembly 22 is rotatably connected to the hook body 211 through the connecting hole 2112. A notch groove 2113 is also provided on the hook body 211. The elastic anti-slip assembly 22 can be swung into the storage groove 2111 to make the device occupy a smaller volume and be convenient to use. When the detonator leg line enters the notch, the elastic anti-slip assembly 22 can automatically seal the notch groove 2113 to prevent the detonator leg line from slipping.

[0056] The cylindrical pin 221 is rotatably installed in the connecting hole 2112, and both ends of the cylindrical pin 221 are fixedly connected with anti-drop buckles 222. This arrangement allows the detonator leg line to be better clamped after entering the gap, thereby making the detonator leg line more anti-dropping. Torsion springs 223 are sleeved near the two ends of the cylindrical pin 221, and one end of the torsion spring 223 is fixedly connected to the cylindrical pin 221, and the other end of the torsion spring 223 is fixedly installed at the bottom of the storage groove 2111, so that under the action of the torsion spring 223, the anti-drop buckle 222 can automatically reset.
