Изобретение относитс к грузозахватньом устройствам, использующим вакуум дл захвата и удержани груза при его подъеме и транспортировке.BACKGROUND OF THE INVENTION The invention relates to load gripping devices using a vacuum to capture and hold a load during lifting and transport.

Известен вакуумный захват, содержащий вакуумную головку, регулирующий клапан, механизм наклона пэловки и механизм подъема, выполненный в виде рычагов l. .Known vacuum pickup containing a vacuum head, a control valve, a tilt mechanism of the saw tube and a lifting mechanism, made in the form of levers l. .

Известна также вакуумна головка, содержаща корпус с размещенным в нем поршнем, на штоке которого в верхней части закреплена грузова серьга 2 .Also known vacuum head, comprising a housing with a piston placed in it, on the rod of which in the upper part of the fixed weight of an earring 2.

Указанные вакуумные захваты не обеспечивают достаточной надежности удержани груза, так как удерживающее усилие в них пропорционально ходу поршн .These vacuum grippers do not provide sufficient reliability to hold the load, since the holding force in them is proportional to the stroke of the piston.

Наиболее близким по технической сущности к описываемому вл етс ручной вакуумный захват, содержащий корпус с выступами, выполненную в корпусе камеру разрежени с установленным в ней поршнем со штоком и шарнирно закрепленные на корпусе рычаги, снабжен .ные подпружиненными защелками и руко тками З .The closest in technical essence to the described is a manual vacuum gripper, comprising a housing with protrusions, a vacuum chamber made in the housing with a piston with a rod installed in it and levers hinged to the housing, provided with spring-loaded latches and handles H.

Недостатком известного захвата вл етс значительна затрата времени на операцию захвата и освобождени груза.A disadvantage of the known grip is the considerable time spent on the grip and release operation.

Целью изобретени вл етс ускорение выполнени операций по захвату груза.The aim of the invention is to accelerate the performance of operations to seize the cargo.

Поставленна цель достигаетс тем, что рычаги выполнены полыми и внутри них установлены подпружиненные т ги, один конец каждой из-которых соединен с подпружиненной защелкой, а второй с руко ткой, причем на штоке выполнены зубь , а на конце каждого рычага жестко закреплена шестерн , зубь которой наход тс в зацеплении с зубь ми штока.The goal is achieved by the fact that the levers are made hollow and inside them spring-loaded rods are installed, one end of each of which is connected to the spring-loaded latch, and the second one is connected to the handle, the gear is fixed on the stem, and the tooth is rigidly fixed to the end of each lever. which are engaged with the teeth of the rod.

Сущность изобретени по сн етс чертежом, где на фиг. 1 изображен общий вид ручного вакуумного захвата; на фиг. 2 - вид захвата сверху; на фиг. 3 - сечение А-А на фиг. 1, на фиг. 4 - сечение Б-Б на фиг. 1.The invention is illustrated in the drawing, where in FIG. 1 shows a general view of a manual vacuum gripper; in fig. 2 - top view of the grip; in fig. 3 is a section A-A in FIG. 1, in FIG. 4 is a section BB in FIG. one.

Claims

The gripper includes a housing 1 with protrusions 2. A discharge chamber 3 with a piston 4 installed in it with a rod 5 is made in the case, and the arms 6 are pivotally attached to the case, equipped with spring-loaded latches 7 and handles 8. Levers are hollow and internal Spring-loaded rods are installed. One end of each of the tg 9 is connected by a spring-loaded latch 7, and the other end is connected to the handle 8. On the rod 5, the tooth 10 is cut on both sides of it, .a gear 11 are rigidly fixed at the end of each lever 6. 12 which interact with the teeth 10 of the rod 5. The latches 7 are pivotally mounted on the axles 13 and are connected by pins 14 through the annular grooves 15 in the cheeks 16 of the lifting arms 6. The knobs 8 swing on the axes 17 and pivotally connected to the rods 9. Gears 11 are rigidly attached to the cheeks 16 of the lifting arms b and pivotally mounted on an axis 18 in the projections 2 of the housing 1. For transporting the gripper in an inoperative position, the clamps 19 are provided in the form of figured lamellar springs for transporting the gripper. The gripping works as follows. The gripper is placed on the surface of the load, the handles 8 are gently released from the clips 19 and once moved to the sides. In this case, the handles 8 rotate around the axes 17 and act on the rods 9, which remove the latches 1 through the pins 1.4. When a certain divorce of the lifting levers b is reached, the handles 8 rotate around the axes 17 in the direction of lift, thus releasing the spring-loaded gi-9, which act through the pins 14 on the latches 7, turning them around the axes 13, and engage them with the projections 2 of the housing 1, thereby fixing the lifting levers and simultaneously through the gears 11 move the rod 5 up, creating a vacuum under the piston 4, P After carrying the load by pressing the handles 8 down, the lifting arms b are released and the piston 4 moves to its original position, and the lifting arms to the vertical position for fixing with clamps 19. These design features make it easier for the worker to work, exclude slinging operations heavy loads, for example, stone facing blocks. According to rough estimates, the safety factor of the load-carrying capacity is about 25. Invention Manual-vacuum gripper, comprising a housing with protrusions, a vacuum chamber made in the housing with a piston with a rod installed in it and levers attached to the housing, spring-loaded latches and handles, characterized in that, in order to accelerate the performance of operations for the seizure of cargo, the levers are hollow and have spring-loaded rods installed inside them, one end of each of which is connected to the spring This second latch has a second handle with a handle, the teeth are made on the stem, and a gear is rigidly fixed at the end of each lever, the teeth of which are in engagement with the stem teeth.
