Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of explosion-proof mechanisms, in particular to an explosion-proof mechanism for a high-pressure oil cylinder joint. Background Art
[0002] The oil cylinder is a hydraulic cylinder. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. The hydraulic pipe joint is a component in the hydraulic system that connects high-pressure oil pipes.
[0003] The hydraulic cylinder pushes the piston by fluid pressure. The internal pressure of the high-pressure cylinder is high. If the staff does not operate properly during the operation, it is very likely that the pressure inside the high-pressure cylinder will be too high, which will cause the joint to explode. Since the joint is made of metal, if an explosion occurs accidentally, debris will fly, which will cause personal danger to the operator. Utility Model Content
[0004] The utility model aims to provide an explosion-proof mechanism for a high-pressure oil cylinder joint to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof mechanism for a high-pressure oil cylinder joint, comprising a joint body, a first explosion-proof shell being detachably installed at one end of the joint body, a second explosion-proof shell being detachably installed at the other end of the joint body, absorption pads being arranged inside the first explosion-proof shell and the second explosion-proof shell, limiting blocks being arranged inside the first explosion-proof shell and the second explosion-proof shell between the two absorption pads, a slot being provided inside the limiting block, a pad being arranged inside the slot, and a plurality of stress supports being arranged on the surface of one end of the pad.
[0006] Preferably, a plurality of jacks are provided through the edge of one end of the first explosion-proof shell, nuts are detachably installed at the jacks on the outer side of the first explosion-proof shell, and the first explosion-proof shell is assembled with the second explosion-proof shell by screws and nuts, and the installation steps are simple.
[0007] Preferably, a plurality of fixing holes are provided at the edge of one end of the second explosion-proof shell, and screws are detachably installed at the fixing holes on the outside of the second explosion-proof shell, so that the first explosion-proof shell and the second explosion-proof shell can wrap the joint body to prevent debris from splashing after the joint body accidentally explodes.
[0008] Preferably, a buffer cavity is provided at one end of the absorption pad, and the buffer cavity has the same shape as the pad, and the buffer cavity has the effect of absorbing impact. After an accidental explosion, the pad can be moved in the buffer cavity under force to reduce the impact on the first explosion-proof shell and the second explosion-proof shell.
[0009] Preferably, the slot is of the same shape as the backing plate, and the backing plate is arranged in the slot and contacts the limit block to clamp the joint body, so that the explosion-proof mechanism of the high-pressure oil cylinder joint can wrap the joint body tightly.
[0010] Preferably, the end surfaces of several of the stress supports are respectively connected to the inner walls of the first explosion-proof shell and the second explosion-proof shell. If the joint body explodes accidentally, the pad will be subjected to impact force, and the stress support will be directly disconnected under the force, which will have a buffering effect and prevent the first explosion-proof shell and the second explosion-proof shell from being damaged due to excessive impact force and causing debris to fly.
[0011] Preferably, one end of each of the first explosion-proof shell and the second explosion-proof shell is provided with a protective sleeve to protect the portion where the joint body is connected to the pipeline.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The explosion-proof mechanism of the high-pressure oil cylinder joint is achieved by placing an absorption pad inside the first explosion-proof shell and the second explosion-proof shell, placing a pad in the buffer cavity opened by the absorption pad, so that the stress brackets arranged on the surfaces of the two pads are respectively in contact with the inner walls of the first explosion-proof shell and the second explosion-proof shell, and then the two limit blocks are installed in the first explosion-proof shell and the second explosion-proof shell. If the high-pressure oil cylinder joint explodes, the impact force generated by the explosion will impact the pad, and the pad will be squeezed, and the stress bracket will be directly broken by the force to absorb part of the impact force. After the stress bracket is broken, the pad will move in the buffer cavity to reduce the impact force on the first explosion-proof shell and the second explosion-proof shell, prevent the first explosion-proof shell and the second explosion-proof shell from being damaged, and block the debris generated by the explosion of the high-pressure oil cylinder joint in the first explosion-proof shell and the second explosion-proof shell to avoid harm to personnel.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0020] like Figures 1 to 3 As shown, the present embodiment is an explosion-proof mechanism for a high-pressure oil cylinder joint, comprising a joint body 1, one end of the joint body 1 is detachably mounted with a first explosion-proof shell 2, and the other end of the joint body 1 is detachably mounted with a second explosion-proof shell (3) on one end of the first explosion-proof shell 2, the first explosion-proof shell 2 and the second explosion-proof shell 3 are made of alloy material and are hard in texture, the first explosion-proof shell 2 and the second explosion-proof shell 3 wrap the joint body 1, and effectively prevent the accidental explosion of the high-pressure oil cylinder joint from causing debris to splash, the first explosion-proof shell 2 and the second explosion-proof shell 3 are both provided with an absorption pad 6, and the first explosion-proof shell 2 and the second explosion-proof shell 3 are both provided between the two absorption pads 6. A limiting block 8 is provided, which will move toward the absorption pad 6 after being impacted. The absorption pad 6 is made of sponge material and has excellent buffering effect. A card slot 10 is provided inside the limiting block 8, and a pad 7 is provided inside the card slot 10. A plurality of stress brackets 14 are provided on one end surface of the pad 7. When the pad 7 is subjected to the impact force generated by the explosion of the joint body 1, the stress bracket 14 will be directly broken by the force and a part of the impact force will be absorbed. After the stress bracket 14 is broken, the pad 7 will move into the buffer cavity 9. The buffer cavity 9 is provided inside the absorption pad 6, which can effectively reduce the impact force of the pad 7 on the first explosion-proof shell 2 and the second explosion-proof shell 3.
[0021] Specifically, a plurality of jacks 5 are provided through the edge of one end of the first explosion-proof shell 2, and nuts 4 are detachably installed at the jacks 5 outside the first explosion-proof shell 2. The first explosion-proof shell 2 is assembled with the second explosion-proof shell 3 by screws 12 and nuts 4, and the installation steps are simple.
[0022] Furthermore, a plurality of fixing holes 13 are provided at the edge of one end of the second explosion-proof shell 3, and screws 12 are detachably installed at the fixing holes 13 on the outside of the second explosion-proof shell 3, so that the first explosion-proof shell 2 and the second explosion-proof shell 3 can wrap the joint body 1 to prevent debris from splashing after the joint body 1 accidentally explodes.
[0023] Furthermore, a buffer cavity 9 is opened at one end of the absorption pad 6, and the buffer cavity 9 has the same shape as the pad 7. The buffer cavity 9 has the effect of absorbing impact. After an accidental explosion, the pad 7 can be moved in the buffer cavity 9 under the force, thereby reducing the impact on the first explosion-proof shell 2 and the second explosion-proof shell 3.
[0024] Furthermore, the slot 10 has the same shape as the backing plate 7, and the backing plate 7 is arranged in the slot 10 and contacts the limit block 8 to clamp the joint body 1, so that the explosion-proof mechanism of the high-pressure cylinder joint can wrap the joint body 1 tightly.
[0025] Furthermore, the end surfaces of several stress brackets 14 are respectively connected to the inner walls of the first explosion-proof shell 2 and the second explosion-proof shell 3. If the joint body 1 accidentally explodes and the pad 7 is subjected to impact force, the stress bracket 14 will be directly disconnected under the force, which has a buffering effect and prevents the first explosion-proof shell 2 and the second explosion-proof shell 3 from being damaged due to excessive impact force and causing debris to splash.
[0026] Furthermore, one end of the first explosion-proof shell 2 and the second explosion-proof shell 3 are both provided with a protective cover 11 to protect the portion of the joint body 1 connected to the pipeline.
[0027] The method of use of this embodiment is as follows: when installing the explosion-proof mechanism of the high-pressure cylinder joint, first place an absorption pad 6 inside the first explosion-proof shell 2 and the second explosion-proof shell 3, and then place a pad 7 in the buffer cavity 9 opened by the absorption pad 6, so that the stress brackets 14 arranged on the surfaces of the two pads 7 are respectively in contact with the inner walls of the first explosion-proof shell 2 and the second explosion-proof shell 3, and then install the two limit blocks 8 in the first explosion-proof shell 2 and the second explosion-proof shell 3, assemble the first explosion-proof shell 2 and the second explosion-proof shell 3 by screws 12 and nuts 4, and wrap the joint body 1 inside. If the joint body 1 explodes, the impact force generated by the explosion will impact the pad 7, and the pad 7 will squeeze the stress bracket 14 under force. The stress bracket 14 will directly break under force and absorb part of the impact force. After the stress bracket 14 breaks, the pad 7 will move in the buffer cavity 9 to reduce the impact force on the first explosion-proof shell 2 and the second explosion-proof shell 3, prevent the first explosion-proof shell 2 and the second explosion-proof shell 3 from being damaged, and block the debris generated by the explosion of the joint body 1 in the first explosion-proof shell 2 and the second explosion-proof shell 3 to avoid harm to personnel.
