The utility model has the following concrete scheme: the utility model provides an improved generation tight instrument of step, is including hook type kelly and activity dop, hook type kelly is including straight rod portion and hook portion, activity dop cover is on straight rod portion, be equipped with L shape cross arm on the relative position of activity dop and hook portion respectively, the L shape cross arm on both sides all is buckled and its tip all sets up or down simultaneously towards the both sides outside.

Furthermore, in the utility model discloses in hook portion presents perpendicular horizontal folding shape structure of buckling, the front end tip position of activity dop presents flat most advanced structure.

Furthermore, in the utility model discloses in L shape cross arm adopts direct welded connection or adopts screw thread swing joint structure with being connected at the position that corresponds.

Further, in the utility model discloses in screw thread swing joint structure is including establishing the screw rod section of L shape cross arm connection position department and establishing the connect the via hole on the connecting piece that corresponds, is located the screw rod section of connect the via hole both sides and locks through two lock nut.

Further, in the utility model discloses in the afterbody department of straight pole portion still is equipped with two and hangs the screw hole.

The utility model discloses an improvement of making on original tight instrument of step, though improve simply, but very big make things convenient for with the use of step tight fit cover instrument, work efficiency when having promoted building templates installation and use has reduced the personnel consumption when operating, has fine in-service use and worth.

In the figure: the steel pipe comprises a steel pipe body, 1-a hanging threaded hole, 2-a straight rod part, 3-an L-shaped cross arm, 4-a movable clamping head, 5-a clamping hook part, 6-a threaded rod part, 7-a locking nut and 8-a steel pipe.

Detailed Description

Referring to fig. 1-7, the utility model relates to an improved generation tight instrument of step, including hook type kelly and activity dop 4, hook type kelly is including straight rod portion 2 and clamping hook portion 5, movable chuck cover is on straight rod portion, be equipped with L shape cross arm 3 on the relative position of activity dop and clamping hook portion respectively, the L shape cross arm on both sides all is buckled towards the both sides outside and its tip all sets up or down simultaneously.

Furthermore, in the embodiment, the hook part is of a vertical and horizontal folding structure, and the front end part of the movable chuck is of a flat tip structure, and the flat tip structure can also be used as a crow bar, namely used for prying things.

Furthermore, in this embodiment, the connection between the L-shaped cross arm and the corresponding portion is a direct welding connection or a threaded movable connection structure.

Furthermore, in this embodiment, the threaded movable connection structure includes a threaded rod section 6 disposed at the connection position of the L-shaped cross arm and a connection through hole disposed on the corresponding connection member, and the threaded rod sections located at both sides of the connection through hole are locked by two locking nuts 7.

Further, in this embodiment, the tail portion of the straight rod portion is further provided with two hanging threaded holes.

The first implementation mode comprises the following steps: referring to fig. 1 and 2, because the movable chuck is in a vertical and transverse folding structure, the L-shaped cross arm is welded on the vertical plate at the upper part of the movable chuck, and the hook part at the other side is also provided with the L-shaped cross arm, the L-shaped cross arms at the two sides can be arranged at corresponding positions or staggered a little.

Embodiment two: referring to the attached

drawings

3 and 4, because the movable chuck is of a vertical and transverse folding structure, the L-shaped cross arms are arranged on the vertical plate at the upper part of the movable chuck through the threaded movable connecting structure, meanwhile, the L-shaped cross arms of the hook part at the other side are also connected through the threaded movable connecting structure, the L-shaped cross arms at the two sides can be arranged at corresponding positions and can also be staggered a little, the advantage of adopting the threaded movable connecting structure for connection is that the L-shaped cross arms can be connected or detached as required at any time, and if the L-shaped cross arms and the locking nuts are detached, the L-shaped cross arms and the locking nuts which are left unused can be matched and placed through the hanging threaded holes to be collected, so that the movable chuck is prevented from being scattered and stacked on a construction site and is not beneficial to management.

The third embodiment is as follows: referring to fig. 5, since the movable chuck is formed in a vertical and horizontal folded structure, the L-shaped cross arm is welded to the front end of the vertical plate at the lower part of the movable chuck, and the hook part at the other side is also provided with the L-shaped cross arm, the L-shaped cross arms at both sides can be arranged at corresponding positions or staggered with each other.

Referring to fig. 7, the schematic diagram of the present invention in use, in particular, is operated as follows: use two sets earlier the utility model discloses a tight instrument symmetry of stepping presss from both sides the template both sides of tight required centre gripping, L shape cross arm locating place on two sets of tight instruments of stepping simultaneously will be unanimous, after tight instrument of stepping presss from both sides tightly, directly place 8 further centre grippings of steel pipe to the template on two sets of L shape cross arms that correspond again, treat after the steel pipe fastens the template centre gripping, will step tight instrument again and strike the lax and get off just can.

Of course, besides the above-mentioned use, other things can be placed or fixed on the L-shaped cross arm, and the use is very flexible.

The utility model discloses a tight instrument of step by step through structural improvement innovation, realizes the diversification in the service function, further strengthens the in-service use value.
