Description

Technical Field

[0001] The utility model relates to the technical field of protection devices for drilling and repairing machines, in particular to a collision protection device for a catwalk conveying arm of a drilling and repairing machine. Background Art

[0002] During the catwalk lifting process, there is a height difference between the plane where the catwalk operator is located and the plane where the drilling platform is located. The catwalk operator has a blind spot in vision and the possibility of accidents exists at any time, which is an important hidden danger to safe operation. The lifting and lowering conveyor arm is an important part of the catwalk working process. During the lifting of the catwalk conveyor arm, there is an information gap between the catwalk operator and the drilling platform staff. Information can only be exchanged through shouting and other methods. Because the environment is too noisy, it is inevitable that information exchange is unclear or gestures are not clearly observed, which will lead to accidents such as collisions between the catwalk conveyor arm and the drilling platform or related workers.

[0003] Therefore, it is necessary to propose a collision protection device for the catwalk conveying arm of a drilling and repairing machine to avoid the occurrence of collision accidents. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art and provides a collision protection device for a catwalk conveying arm of a drilling and repairing machine.

[0022] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific illustrations.

[0023] Embodiment 1:

[0024] like Figure 1 and Figure 2As shown, this embodiment provides a collision protection device for a catwalk conveyor arm of a drilling and repairing machine, comprising a base 1 and a ramp 2, wherein the ramp 2 is arranged at an obtuse angle to the base 1 and is fixedly connected by bolts, the base 1 is rotatably connected to a support arm 3 by a pin shaft, the top of the support wall is rotatably connected to a conveyor frame 4 by a pin shaft, the head end of the conveyor frame 4 is slidably connected to the ramp 2 by a guide rail and a rail wheel, the conveyor frame 4 is screwed with an anti-collision sensor 5, and the anti-collision sensor 5 is arranged in pairs side by side at the head end of the conveyor frame 4, as shown in FIG. Figure 3 and Figure 4 As shown, the outer side of the anti-collision sensor 5 is wrapped with a buffer layer 6 , and the buffer layer 6 can mitigate the impact force on the anti-collision sensor 5 .

[0025] Preferably, a hydraulic cylinder 7 is installed on the base 1 , and the hydraulic cylinder 7 drives the supporting wall to rotate relative to the base 1 .

[0026] Preferably, a catwalk solenoid valve 8 is fixedly mounted on the base 1 , and the catwalk solenoid valve 8 is connected to the oil circuit of the hydraulic cylinder 7 and controls the on-off of the oil circuit of the hydraulic cylinder 7 .

[0027] Preferably, an electric control box 9 is fixedly mounted on the base 1 , and the electric control box 9 is connected to the catwalk solenoid valve 8 and the anti-collision sensor 5 through cables.

[0028] Preferably, an alarm 10 is fixedly mounted on the base 1, and the alarm 10 is connected to the electric control box 9 via a cable.

[0029] Preferably, a remote controller is further included, and the remote controller is connected to the electric control box 9 via a wireless signal. An operating handle is provided on the remote controller, and a control signal can be transmitted to the electric control box 9 by operating the operating handle, so that the electric control box 9 controls the catwalk solenoid valve 8 and the alarm 10.

[0030] Preferably, the alarm 10 is an explosion-proof sound and light alarm 10.

[0031] Preferably, the buffer layer 6 is made of rubber.

[0032] When working, Figure 1 and Figure 5As shown, the catwalk anti-collision sensor 5 is a switch sensor. The sensor converts the signal into an electrical signal and inputs it into the PLC in the electric control box 9 for data processing. The model of the PLC is S7-1500. At the same time, according to the on-site catwalk operating conditions, the operating knob on the electric control box 9 can be used to set whether to add catwalk anti-collision protection. When the head end of the conveyor frame 4 touches an obstacle, the current action of the catwalk will stop immediately, and all actions will be inoperable. At the same time, the alarm 10 of the alarm device will immediately start to warn the operator of a collision, which needs to be handled in time. The digital display on the electric control box 9 displays the relevant alarm code, and the relevant staff can view the digital display. The alarm code on the digital display can be used to understand the reason for the alarm 10. Except for the emergency stop button on the remote control, which can work normally, the outputs of all other action control buttons of the catwalk are invalid. The catwalk solenoid valve 8 has no input and does not operate to prevent the catwalk from causing damage to equipment or personnel due to secondary action. After the obstacle is removed, the operating handle of the conveyor arm needs to be reciprocated three times on the catwalk remote control to release the action restriction of the remote control. At the same time, the reset button on the electric control box 9 is pressed to stop the alarm 10 of the alarm device, clear the relevant fault code displayed on the digital display on the electric control box 9, and restore the control input to the catwalk solenoid valve 8, so that the catwalk can operate normally.

[0033] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
