Detailed Description

The present invention is described in detail below with reference to the drawings, which are intended to illustrate preferred embodiments of the present invention and not to limit the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, and are only used for describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to be referred to must have a specific orientation and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention.

The utility model provides a drag hammer for dismantling side forms, as shown in fig. 2-6, includes columniform stripping rod 4, the surface both sides of stripping rod 4 weld respectively first baffle 7 and second baffle 8, sliding connection has counter weight hammer 5 on stripping rod 4 between first baffle 7 and second baffle 8, the outer fixed surface of counter weight hammer be connected with handle 6, first baffle 7 and second baffle 8 keep away from and still weld a plurality of reinforcing ribs 9 between the surface of counter weight hammer 5 one side and the surface of stripping rod 4, the both ends of stripping rod all be equipped with the external screw thread to can dismantle fixedly connected with stripping assembly through the external screw thread.

This is novel can in time change the form subassembly of tearing open of damage through the mode that can dismantle the connection to the life of hammer is drawn in the extension, simultaneously, also can make this novel multiple form occasion of tearing open that is applicable to through changing, application scope is wide, convenient to use.

As shown in fig. 2-5, the counterweight hammer 5 is also cylindrical, a sliding hole penetrating through the left and right end faces is formed in the axis of the counterweight hammer, the stripping rod 4 penetrates through the sliding hole and is slidably connected with the sliding hole, the first baffle 7 and the second baffle 8 are annular plate-shaped structures coaxial with the stripping rod, and an inner hole of each annular plate-shaped structure is welded to the outer surface of the stripping rod.

As shown in fig. 2-5, the form removal assembly is a form removal hook 10, and the end of the form removal hook 10 is provided with a threaded seat through which the form removal hook is screwed with the external thread at the end of the form removal rod.

As shown in fig. 1, a plurality of rib plates 2 are arranged on the outer side of a side formwork 1, pull holes 3 are formed in the rib plates 2, when the side formwork is dismantled, a formwork removal hook is inserted into the pull holes 3, handles are held by two hands, a counterweight hammer is pulled to impact a baffle far away from one side of the side formwork, the baffle transmits impact force to the formwork removal hook, the formwork removal hook applies pulling force to the pull holes, and therefore formwork removal is achieved through repeated impact.

As shown in fig. 2-5, the stripper hook 10 is formed by bending round steel 16, and a convex block 17 is arranged on the inner side of the end part of the stripper hook far away from the screw seat.

The round steel 16 is bent to form the form removal hook 10, and the advantages are that: in the form removal process, the form removal hook and the pull hole can rotate relatively, the round steel 16 can enable the rotation to be smoother, and obstruction caused by ineffective friction is avoided. The function of the projection 17 is to prevent the stripping hook from being removed from the drawing hole during the stripping process.

As shown in fig. 2, the form removal assembly is a sleeve 15, the inner surface and the outer surface of the sleeve 15 are respectively provided with an internal thread and an external thread, the internal thread is in threaded connection with the end of the form removal rod, and the external thread is matched with a nut welded on an embedded steel template or an embedded mold box. The sleeve is screwed into the nut, so that the pre-buried steel template or the pre-buried mold box is assisted to be disassembled. The size of the sleeve can be changed according to the size of the nut.

As shown in fig. 4, the form removal assembly is a prying shovel 12, and one end of the prying shovel 12 is provided with a mounting seat and is in threaded connection with the end part of the form removal rod through the mounting seat. Need use the crowbar in some form removal occasions, this is novel to realize the function of crowbar through spiro union sled shovel 12.

As shown in fig. 4 and 5, an annular reaction plate 13 is further coaxially and slidably connected to the outer surface of the stripping rod between the second baffle and the counterweight, a compression spring 14 is sleeved outside the stripping rod between the reaction plate 13 and the second baffle, and two ends of the compression spring 14 are respectively connected to the outer surfaces of the reaction plate and the second baffle. When the counter weight hammer is used, the counter weight hammer can impact the counter force plate 13 due to self inertia and tension, the compression spring 14 compresses energy storage, and when the counter weight hammer is moved reversely, the elastic force of the compression spring can accelerate the movement of the counter weight hammer, so that the impact force and the impact speed of the counter weight hammer on the baffle on the opposite side are improved, the mold removal effect is improved, and manpower is saved.

As shown in fig. 5 and 6, the device further comprises a C-shaped frame 18, wherein the C-shaped frame 18 is formed by welding or bending a steel plate, a universal wheel 21 with a brake pad is arranged on the lower surface of the bottom end of the C-shaped

frame

18, and 19,2 connecting lugs 19 are welded on the lower surface of the top end of the C-shaped frame 18 and the middle part of the upper end of the handle 6 and connected through a rope 20.

Because the long-term hand-held counter weight hammer amount of labour is too big, so this is novel still to be equipped with C shape frame 18, lifts up the counter weight hammer through rope 20, only needs to promote during the use that handle 6 removes about, makes the counter weight hammer striking keep away from the baffle of mould one side can to workman's amount of labour has been reduced by a wide margin.
