When detecting a pipeline, a detector is generally required to be thrown into the pipeline to be detected. There is the input device among the prior art, place the detector in on the input device, through manual drive alright in throwing the detector into the pipeline that awaits measuring. However, the operation mode is mainly suitable for non-pressure pipelines, the throwing difficulty is high for the throwing work of the pipelines with pressure, and when the pressure of the pressure pipelines is higher, the manpower can not meet the requirement of pushing.
In order to solve the problems in the prior art, the present invention provides a detector throwing device 1, including: mount pad 2, mount pad 2 have installation cavity 5, and mount pad 2 is used for and awaits measuring pipeline sealing connection to make installation cavity 5 and the lumen intercommunication of the pipeline that awaits measuring, so can be so that the lumen of the pipeline that awaits measuring is in the closed condition, can satisfy the detection demand of the pipeline that awaits measuring under operating condition. The picking device 3 comprises a mounting rod 9 movably arranged in the mounting cavity 5 and a plurality of claw bodies 10 movably arranged at the end part of the mounting rod 9, wherein each claw body 10 has a moving stroke which is close to each other and a moving stroke which is far away from each other, so that the detector is picked in the moving stroke which is close to each other, and the detector is thrown in the moving stroke which is far away from each other; and the driving device 4 comprises a picking driving mechanism 26 and a throwing driving mechanism 27, the picking driving mechanism 26 is connected with each claw body 10 so that each claw body 10 has a movable stroke approaching to or separating from each other, and the throwing driving mechanism 27 is in driving connection with the mounting rod 9 so that the mounting rod 9 has a movable stroke moving along the extending direction of the mounting cavity 5. It can be understood that when the device is used, the pick-up driving mechanism 26 drives the claw body 10 to pick up the detector, then the release driving mechanism 27 drives the mounting rod 9 to approach the pipeline to be detected, and when the device moves to the target position, the pick-up driving mechanism 26 is driven to drive the claw body 10 to release the detector to the pipeline to be detected, so that the release of the detector can be completed.
According to the detector throwing device 1 provided by the invention, the mounting seat 2 can be hermetically connected with the pipeline to be detected, so that the closed environment of the pipeline to be detected is kept, and the detection of the pipeline to be detected in a working state can be realized; secondly, the pick-up driving mechanism 26 can drive the claw body 10 to pick up or put in the detector, so that the operation is simple, and the putting efficiency of the detector is improved; in addition, the throwing driving mechanism 27 can drive the pickup device 3 to be close to the pipeline to be detected, any position of the device can be kept static in the throwing process under the condition that the holding force does not need to be provided manually, the device is suitable for the non-pressure pipeline or the pipeline with pressure, and the applicability of the detector throwing device 1 is improved.
The driving manner of the claw body 10 is various, and in the prior art, there are hydraulic oil cylinders and other driving mechanisms for driving the claw body 10 to open and close to complete the picking and releasing operation of the claw body 10. In order to simplify the driving mechanism, in the technical scheme provided by the invention, each claw body 10 is movably hinged at the end part of the mounting rod 9 so as to have a picking state close to the mounting rod 9 and a throwing state far from the mounting rod 9; the pick-up device 3 comprises a movably arranged locking mechanism 11, and the locking mechanism 11 is used for locking each claw body 10. It should be noted that, under the action of the hinge force, the free state of each claw body 10 should be away from the mounting rod 9, and when the locking mechanism 11 is locked to each claw body 10, each claw body 10 maintains the pick-up state, and when the locking mechanism 11 is disengaged from each claw body 10, each claw body 10 is switched to the release state, i.e., the free state. The pickup drive mechanism 26 is used to drive the lock mechanism 11 to lock or unlock each pawl 10. With this arrangement, the configuration of the pickup device 3 can be simplified, and the state switching of the claw body 10 can be completed without a complicated drive mechanism.
Specifically, in the technical solution provided by the present invention, the inner side of one end of each claw body 10 close to the mounting rod 9 is provided with a hook 21, and the locking mechanism 11 includes a driving rod 25 and a plurality of claws 24 arranged at the end of the driving rod 25; referring to fig. 2 and 4, a strip-shaped slot is formed inside the hook 21, and the claw 24 can extend into the slot to be correspondingly clamped with the hook 21. In addition, the mounting rod 9 is provided with a rod cavity 12 extending along the length direction thereof, and the driving rod 25 is movably arranged in the rod cavity 12 to drive each clamping jaw 24 to be clamped or separated from the corresponding clamping hook 21; the pickup drive mechanism 26 is drivingly connected to the drive rod 25 such that the drive rod 25 has a stroke that travels along the rod cavity 12. It should be noted that, in the initial state, each claw 24 is clamped to the corresponding hook 21, and at this time, the claw body 10 is in the pick-up state, and can pick up the detector; when the driving rod 25 moves towards the direction far away from the hook 21, the claws 24 are separated from the hook 21, each claw body 10 is in a throwing state, and the detector is arranged far away from the driving rod 25 and separated from the claw body 10 under the influence of gravity; thus, the pick-up and drop detector can be achieved by moving the driving rod 25 to change the state of the claw body 10.
Referring to fig. 1-3, a sleeve 13 is sleeved on one end of the mounting rod 9 away from the mounting base 2, the sleeve 13 has a barrel cavity 14, the rod cavity 12 is communicated with the barrel cavity 14, and the driving rod 25 is movably arranged in the barrel cavity 14; the upper end face of the sleeve 13 is provided with a mounting hole 15, the picking drive mechanism 26 comprises a handle 28 movably arranged in the mounting hole 15 in a penetrating way, and the handle 28 is connected with the drive rod 25 in a driving way and can drive the drive rod 25 to move along the barrel cavity 14. In the technical scheme provided by the invention, the mounting hole 15 is a screw hole, the handle 28 is in threaded connection with the mounting hole 15, and the driving rod 25 can be driven to move downwards by screwing the handle 28, in other words, the driving rod 25 can be driven to move upwards by screwing the handle 28 reversely.
Furthermore, a pressing plate 29 is further arranged at the joint of the handle 28 and the driving rod 25, a spring 30 is arranged in the barrel cavity 14, the spring 30 is movably sleeved outside the mounting rod 9, one end of the spring 30 abuts against the pressing plate 29, and the other end of the spring 30 abuts against the inner wall of the sleeve 13. It should be noted that the length of the driving rod 25 is greater than that of the mounting rod 9, and a distance between the driving rod 25 and the mounting rod 9 is a deformation distance of the spring 30, so that when the pressing plate 29 moves to abut against the upper end face of the mounting rod 9, the driving rod 25 moves to the maximum movement stroke. Therefore, the distance can be designed to be slightly larger than the length of the hook 21, so that when the handle 28 moves downwards to the extreme position, the hook 21 can be ensured to be separated from the claw 24 at the moment, and the unlocking release detector is carried out on the claw body 10; of course, the distance also plays a certain limiting role in the movement of the handle 28, and prevents the detector from being influenced by the overlarge movement displacement of the handle 28. It should also be noted that, in the initial state (without movement of handle 28), spring 30 is in a compressed state, and compressed spring 30 applies an upward bias to driving rod 25, opposite to the force of pawl 24 to disengage from pawl 21, so as to ensure stable engagement of pawl 21 with pawl 24. In addition, in the technical scheme provided by the invention, the sleeve 13 is provided with the cylinder 16 and the lower end cover 17, the lower end cover 17 is arranged at the downward opening of the cylinder 16 and is detachably connected with the cylinder 16, so that the spring 30 and the pressing plate 29 can be conveniently installed, and the pipe wall of the driving rod 25 is fixedly connected with the lower end cover 17 through bolts, so that the installation and the disassembly are convenient.
