Description

Изобретение относитс к подъемно-транспортному машиностроенню, а именно к конструкции нредохранительных устройста устанавливаемых на конвейерах с измен емым углом наклона и обеспечивающих фиксацию положени рамы койвейера , в случае обрыва трособлочной системы подъема.The invention relates to a hoisting and transport machinery industry, namely, to the design of safety devices installed on conveyors with a variable angle of inclination and ensuring fixation of the position of the frame of the coyveier, in the event of a break of the cable-lifting system.

Известно предохранительное устройство, которое содержит подвижный стержень, останавливаемый в случае обрыва троса с помощью тормоза И)..Known safety device, which contains a movable rod, stopped in the event of a cable break with a brake And) ..

Однако тормоз имеет довольно сложную конструкцию и усилие торможе ш никак не св за1юс нагрузкой на все устройство и, следователшо, должно быть, выбрано с большим запгюом.However, the brake has a rather complicated construction and the braking force is not at all due to the load on the entire device and, therefore, must be chosen with a large punching pad.

Известно также предохранительное устройство дл наклонного конвейера, которое содержит трособлочную систему, установленную на раме конвейера, св занную с подвижной штангой и стопорным зажимным механизмом 2.It is also known to have a safety device for inclined conveyor, which comprises a cable-blocking system mounted on the conveyor frame associated with a movable rod and a locking clamping mechanism 2.

Однако это устройство требует применшн достаточно сильной пружины в зажимном механизме дл надежного захвата стержн при больших нагрузках на раму конвейера.However, this device requires the use of a sufficiently strong spring in the clamping mechanism to securely grip the rod under heavy loads on the conveyor frame.

В то же врем сильна пружина в услови х перемещени рамы конвейера без нагрузки, без надобности способствует заклиниванию стержн мешает оперативной регулировке положени At the same time, a strong spring in terms of moving the conveyor frame without load, unnecessarily contributes to the seizure of the rod prevents the operational adjustment of the position

Цель изобретени - снижение нагрузок на раvty конвейе{т при q)aбaтывaнии предохранительного уафойства.The purpose of the invention is to reduce the load on the conveyor belt {t at q) the operation of the safety condition.

.Дл этого зажимной механизм вьшолнен в виде закр шей ой на раме Г-образной скобы с расволоже ва11мн в ней подаружиненным рычагом, установленными на штанге, при этом рычаг соедщнен с трособпо к системой.For this purpose, the clamping mechanism is implemented as a closed hinge on the frame of the L-shaped bracket with the wavnm in it with a spring-loaded lever mounted on the rod, while the lever is connected to the system.

Claims

The frame of the conveyor and 1 is mounted on the chassis 2 ,. having a frame 3 movable on frame 1. A movable stand 3 has a roller 4 pivotally connected to the mobile ipanga 5. On the frame of the conveyor 1 is installed a clamping mechanism consisting of an L-shaped bracket 6 fixedly mounted on the frame of the conveyor 1 and the spring-loaded lever 7. In the bracket 6, a jumbo hole, in which the rod 5 goes freely with a large gap. To end 7, the end of the cable 8 is attached, the second end of it is stored in the winch 9 mounted on the frame of the conveyor 1 and passes through the pulleys 10 and il. The device works as follows. When the drum of the winch 9 rotates, the cable 8 that cuts through the bolts 10 and 11 moves the rod S and, accordingly, the movable rack 3 of the chassis 2. When Lifting and lowering the conveyor frame 1, the cable 8 pulls on the movable rack 3 of the chassis 2, the lever 7 is pressed to the side face of the bracket 1b7Pr§ Shm1gganga 5 freely passes through the holes 1 in the speed, and the arm 7, giving the opportunity to Lift and lower the conveyor frame 1. If the cable 8 breaks the lever 7 under the action of the spring 12 and carried away the movement; rods S in preparation, shown in FIG. 3 by the arrow, the hatch, in which the lateral plane of the lever 7 forms an angle a with the contact line, equal to or smaller than the friction angle between the rod 5 and the grommet 6 forming the aperture. At the same time, the lever 7 wedges the rod 5, making it impossible to move the chassis 2 on the frame of the conveyor. When restoring the cable 8, the lever 7 takes the initial position in which the movement of the rod 5 passes unhindered. Claims of the Invention A safety device for an overhead conveyor comprising a cable-blocking system installed {u1b on the frame, connected grandchild) with a movable rod and a locking clamping mechanism, from the fact that, in order to reduce the loads on the frame of the conveyor, at q a6aTbraa the safety device The landing mechanism is embodied in the form of an L-shaped bracket fixed on the frame with the pedal (1) installed on it) with a lever mounted on a movable rod, while the lever is connected to a cable block system.
