Abstract

The utility model discloses a rotatable brick clamp which consists of a horizontal bracket, a front clamping arm, a rear clamping arm and a clamping cylinder, wherein the middle parts of the front clamping arm and the rear clamping arm are symmetrically hinged to the front and rear sides of the horizontal bracket; the clamping cylinder is hinged between the upper ends of the front clamping arm and the rear clamping arm; a rotating device is arranged above the horizontal bracket; the rotating device consists of an upper turntable, a pressure bearing and a lower turntable; a vertical shaft is fixed on the lower turntable; the upper turntable is arranged on the vertical shaft through a bearing; a horizontal connecting rod is fixed on the upper turntable; a horizontal shaft is fixed at the upper end of the vertical shaft; two movable pulleys are respectively arranged at two ends of the horizontal shaft; movable supports are fixed at two ends of the horizontal connecting rod; short upright posts are fixed on the horizontal bracket; the movable supports sleeve the short upright posts; one ends of connecting plates are hinged with the upper ends of the front clamping arm and the rear clamping arm; the other ends of the connecting plates are symmetrically hinged to two sides of the movable supports. According to the rotatable brick clamp, the loading and unloading difficulties generated when the brick stack orientation is inconsistent with the clamping direction of the brick clamp and the loading and unloading site is narrow and small are solved.

Description

Rotatable brick clamp

Technical field

The utility model relates to automatic loading and unloading technical field, is specifically related to a kind of rotatable brick clamp.

Background technology

With the immediate prior art of the utility model be the utility model patent applied for of the applicant " automatic loading and unloading fortune brick car (CN103303181A) ", the brick clamp that this car uses can not rotate, and stamps and when inconsistent with the clamping direction of brick clamp, has been difficult to the handling that brick is stamped when brick.Particularly in the time loading, must first adjust the position of fortune brick car, the compartment of transporting brick car is stamped towards consistent along length direction and brick, and compartment tail end just be stamped to brick, the clamping direction of guarantee brick clamp is stamped towards consistent with brick like this, thereby completes smoothly the loading that brick is stamped.But in the time of handling narrow field, cause handling difficulty, even cannot complete handling.

Utility model content

The purpose of this utility model is to provide a kind of rotatable brick clamp, has solved brick and has stamped the handling difficulty in the time of and handling narrow field inconsistent with the clamping direction of brick clamp, has realized the smooth handling of narrow and small place.

The technical scheme that the utility model adopts is: a kind of rotatable brick clamp, and described brick clamp is made up of horizontal stand, front jig arm, rear jig arm and clamping oil cylinder; The middle part symmetry of described front jig arm, rear jig arm is hinged on the both sides, front and back of horizontal stand, and front jig arm, rear jig arm are hinged with clamping oil cylinder between upper end; The top of described horizontal stand is provided with slewing arrangement, described slewing arrangement is made up of top rotary table, pressure bearing and lower rotary table, on lower rotary table, be fixed with vertical shaft, top rotary table is arranged on vertical shaft by bearing, is fixed with waling stripe on top rotary table, and vertical shaft upper end is fixed with horizontal shaft, two movable pulleys are arranged on respectively the two ends of horizontal shaft, the two ends of waling stripe are fixed with expansion bearing, are fixed with column on horizontal stand, and expansion bearing is sleeved on column; The upper end of one end of connecting panel and front jig arm, rear jig arm is hinged, and other end symmetry is hinged on the both sides of expansion bearing.

The advantage that compared with the prior art the utility model has and effect:

1, solve brick and stamped the handling difficulty in the time of and handling narrow field inconsistent with the clamping direction of brick clamp, realized the smooth handling of narrow and small place.

2, regardless of piled bricks towards, all can rotate brick clamp by slewing arrangement and make it align piled bricks, realize comprehensive handling that brick is stamped.

Fig. 2 is the structural representation of the utility model slewing arrangement.

Detailed description of the invention

Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.

A kind of rotatable brick clamp, is made up of horizontal stand 21, front jig arm 22, rear jig arm 23 and clamping oil cylinder 24; The middle part symmetry of described front jig arm 22, rear jig arm 23 is hinged on the both sides, front and back of horizontal stand 21, and between front jig arm 22, rear jig arm 23 upper ends, is hinged with clamping oil cylinder 24; The top of described horizontal stand 21 is provided with slewing arrangement 25, described slewing arrangement 25 is made up of top rotary table 26, pressure bearing 27 and lower rotary table 28, on lower rotary table 28, be fixed with vertical shaft 29, top rotary table 26 is arranged on vertical shaft 29 by bearing, on top rotary table 26, be fixed with waling stripe 30, vertical shaft 29 upper ends are fixed with horizontal shaft 31, two movable pulleys 20 are arranged on respectively the two ends of horizontal shaft 31, the two ends of waling stripe 30 are fixed with expansion bearing 33, on horizontal stand 21, be fixed with column 32, expansion bearing 33 is sleeved on column 32; The upper end of one end of connecting panel 34 and front jig arm 22, rear jig arm 23 is hinged, and other end symmetry is hinged on the both sides of expansion bearing 33.

Principle of work: because brick clamp is suspended on slewing arrangement 25 by waling stripe 30, expansion bearing 33 and connecting panel 34, and by column 32, brick clamp is located, prevent brick clamp distortion.Slewing arrangement 25 is connected with elevator by movable pulley 20 and steel rope.No matter load while still unloading, if when brick clamp can not align piled bricks, be that brick is stamped when inconsistent with the clamping direction of brick clamp, can manually rotate brick clamp by slewing arrangement 25 makes it align piled bricks, therefore, regardless of piled bricks towards, rotate brick clamp by slewing arrangement 25 and realize comprehensive handling, be particularly suitable for the handling of narrow and small place.

Before and after the utility model, two clamping limb upper ends are by connecting panel 34 and the hinged formation of expansion bearing 33 " V " type structure, two clamping limbs clamp after piled bricks in lifting process by the effect of clamping oil cylinder 24, because promoting slewing arrangement 25 by movable pulley 20, steel rope rises, and then make expansion bearing 33 there is the trend moving up along column 32, this trend acts on two clamping limbs by connecting panel 34, make two clamping limb lower ends in lifting process, remain certain gripping power, even clamping oil cylinder 24 et out of orders, this Clamping force also can not disappear, further ensure reliability and the safety of two clamping limb clampings.

Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, thus all equivalent variations of being done with content described in the utility model claim, within all should being included in the utility model claim scope.
