Abstract
The utility model relates to an exhaust device for a headframe telescopic hydraulic cylinder. The exhaust device comprises a joint, a solenoid valve, a nozzle and a cable, wherein the solenoid valve is connected with the headframe telescopic hydraulic cylinder through the joint; the nozzle is arranged on the solenoid valve and is communicated with the headframe telescopic hydraulic cylinder through the solenoid valve; and the solenoid valve is connected with an external power supply through the cable. The exhaust device has a simple structure and high working efficiency, is convenient to operate and can be widely applied to equipment.
Description
Technical field
The utility model relates to a kind of venting gas appliance, particularly relates to a kind of derrick extending cylinder venting gas appliance.
Background technique
Vehicle carried type well repairing machine or vehicle carried type rig because the extending cylinder stroke is big, after pressure oil enters telescopic cylinder, still can have air in the cylinder in derrick hoists process.Because air has compressibility and hysteresis dilatancy, can cause telescopic cylinder and whole hydraulic system at work vibration and creep, influence the telescopic cylinder proper functioning.So need on the derrick telescopic cylinder, establish relief opening, and the relief opening on the derrick telescopic cylinder in the past all is that simple outlet valve or ball valve are installed, derrick hoists and needs the workman to climb up derrick in the process to exit, bring very big inconvenience to work, thereby reduced working efficiency.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, easy to operate, the derrick extending cylinder venting gas appliance of high working efficiency.
In order to address the above problem, the utility model by the following technical solutions:
Derrick extending cylinder venting gas appliance comprises joint, solenoid valve, nozzle and cable, and solenoid valve is connected with the derrick telescopic cylinder by joint, and nozzle is installed on the solenoid valve, and nozzle communicates with the derrick telescopic cylinder by solenoid valve, and solenoid valve is connected with external power supply by cable.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, and cost is low, and is easy for installation, and stable performance can realize remote operation, do not need the workman to climb up the derrick operation, thereby reduced operation easier, improved working efficiency.
Description of drawings
Fig. 1 is the utility model mounting structure schematic representation;
Fig. 2 is the I part enlarged view of Fig. 1.
Embodiment
Derrick extending cylinder venting gas appliance, as shown in Figure 1 and Figure 2, comprise joint 1, solenoid valve 2, nozzle 3 and cable 4, solenoid valve 2 is connected with derrick telescopic cylinder 5 by joint 1, nozzle 3 is installed on the solenoid valve 2, nozzle 3 communicates with derrick telescopic cylinder 5 by solenoid valve 2, and solenoid valve 2 is connected with external power supply by cable 4.
When solenoid valve 2 by cable 4 electric after, the solenoid valve 2 inner coils that twine produce magnetic force, and the spool of solenoid valve 2 is held, solenoid valve 2 is opened, and realizes degassing function; Otherwise solenoid valve 2 is by spring reset in the valve group, and solenoid valve 2 closures are closed venting gas appliance.
