Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0013] Such as figure 1 , 2 As shown, the automatic wall-attaching device for the test equipment in the hole of the present invention includes a circular tubular wall-attaching body 1, and a long groove 9 is formed along the vertical direction from the upper half of the side wall of the wall-attaching body 1 to the top, The top in the adherent body 1 is provided with a horizontal horizontal axis 10, the movable support arm 2 is slightly shorter than the long groove 9 and hangs on the horizontal axis 10, and the horizontal axis 10 is covered with a torsion spring 3, two of the torsion springs 3 One end of the torsion arm is supported on the inner wall of the wall-adhering body 1, and the other end is supported on the movable support arm 2, so that one end of the movable support arm 2 can extend out of the wall-attaching body 1 through the long g...

The invention discloses an automatic wall-attaching device for testing equipment in a hole, which comprises a circular tube-shaped wall-attaching body, and a long groove is opened along the vertical direction from the upper half of the side wall to the top of the wall-attaching body. The top of the body is provided with a horizontal axis, and the movable support arm is slightly shorter than the long groove and is suspended on the horizontal axis. There is a torsion spring on the horizontal axis, and a pulley is arranged at the lower part of the movable support arm, and the outer edge of the diameter of the pulley protrudes As for the movable support arm, a lock pin is arranged at the bottom of the movable support arm, and a locking and unlocking lever which can move up and down is arranged in the wall-adhering body. The bottom end of the lock-in unlocking lever is provided with a rod contact, and the top of the lock-in unlocking lever is provided with a lock hook. Hole-down state; when the wall-attaching device reaches the bottom of the hole, the movable arm is automatically unlocked and opened, and the wall-attaching device is in the testing state. The wall sticking device of the present invention is small in size, light in weight, reliable in sticking to the wall, convenient to move between measuring points in the hole, has the same wall sticking effect in deep holes and shallow holes, supports the wall automatically, and greatly improves work efficiency.
Description
technical field [0001] The invention relates to engineering testing equipment, in particular to an automatic wall-attaching device for in-hole testing equipment. Background technique [0002] In conventional engineering drilling technology, the testing system in the drilling consists of a probe and a wall-attaching device. Currently, the wall-attaching device for in-hole testing equipment adopts the airbag inflation method, the electromagnet release arm method, the hydraulic control arm method and the rope pull method. The arm method and other principles are used to manufacture, but the equipment prepared above is huge, complicated to manufacture, inconvenient to use, and even can only test very shallow boreholes, and there is a waste of manufacturing materials and electric energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic wall-attaching device for testing equipment in a hole, which is small in...
