Abstract
The utility model discloses a self-dismounting construction hoist with a safety protector, which is composed of a machine body, a ridge spar, a ground beam, a suspension cage, a directly attached walled beam, an obliquely attached walled beam, and a suspension rod, wherein, the machine body is composed of standard sections; the suspension cage adopts a framework structure and is provided with a lever type rope breaking automatic protector and a plug-in type safe protector. Adopting double insurance, the utility model solves the problem of accidental steel cable breaking in the operation of a construction hoist. The suspension cage can brake instantly and automatically, so the utility model enables the suspension cage not to fall down and ensures mechanical and personal safety. The utility model has the advantages of easy fabrication, convenient assembly and disassembly, small land occupation, no cable rope, and high safety, can be widely used in the construction and the maintenance of middle and high buildings, and is a vertical transport machinery with an extensive application range.
Description
The utility model relates to the vertical transportation machinery of usefulness such as the middle and high layer of a kind of confession building main body construction, decoration and supporting operation engineering, tall and big facility maintenance activity, and especially a kind of safety guard that has can be installed the wall-attachment building hoist that sets up voluntarily.
In present building operation, vertical transportation machinery has a variety of.A kind of is tower crane, but it can not adapt to the needs of decoration and other matching construction operation fully, and wall-attached external application elevator cooperates fine with tower crane, but its price is higher, and owing to the reason on the self structure can not be customer satisfaction.And cabinet frame, self-support crane and traditional old-fashioned portal frame, though its structure is simple, but safety is relatively poor, installation needs other elevator machinery to assist to finish, especially their stability needs to socket cable wind rope around support body and guarantees its stability, can not adapt to the needs of modernized metropolis building and improvement project construction.
The utility model building hoist design-calculated purpose provides that the manufacturing that the building operation of the middle and high layer of a kind of confession use is simple, cheap, easy accessibility, occupation of land scope are little, do not establish cable wind rope, the vertical transportation machinery of safe and reliable, applied range.
The body that the utility model is made up of standard knot, Tian Liang, grade beam, cage, straight attached wall bar, oblique attached wall bar, suspension rod are formed; it is characterized in that cage adopts framed structure; its both sides are equipped with the disconnected rope of lever automatic safety device; the movable pulley frame is installed on the crossbeam; plug-in type safety guard and suspension rod are fixed on the two ends of crossbeam, and a side of cage is fixed with the push-and-pull safety door.The disconnected rope of said lever automatic safety device is in the guide track inner slide of support body, lock body frame is connected with bolt of rear end plate by stay-bolt with strap of the brake body, sliding tie rod, one end of two-thread screw is fixed on the slip arm-tie, the other end is fixed on the lock body frame, pressure spring one end is fixed on the lower end of lock body frame, the other end is installed on the stage clip adapter plate, and driving bolt is connected on the slip arm-tie; Movable pulley is assemblied on the movable pulley frame, and the two ends of tension spring connect the crossbeam of movable pulley frame, cage respectively, and double-deck pulley links to each other with the plug-in type safety guard with the disconnected rope of lever automatic safety device by stay cord, and detent rail is fixed on the lower end of movable pulley frame.Said plug-in type safety guard; it is characterized in that this device is inserted in the standard knot by inserted link; draw ring is connected the inserted link tail end; inserted link is fixed on the guiding wheel carrier assembly; one end of tension spring is fixed on the inserted link tail end; the other end is fixed on the cage crossbeam, and draw ring is connected with the guiding stay cord, and the guiding stay cord is connected with the movable pulley frame by double-deck pulley.Said push-and-pull safety door is characterized in that, it is made up of sliding door, guiding wheel carrier, track adjusting wheel, guide wheel shaft, is fixed on a side of the operation of cage.Said suspension rod is fixed on cage column both sides, and chain block is fixed on the suspension rod.
The principle of work of the disconnected rope safety guard of the relevant building hoist of the utility model is achieved in that
When cage (5) when moving up and down; because the position-limiting action of the detent rail (27) on the movable pulley frame (15); can only make movable pulley frame (15) segment distance that moves up; be fixed on the lever of cage both sides and the stay cord (25) (42) of the disconnected rope of plug-in type automatic safety device this moment moves up thereupon; move the web member that makes it to leave standard knot (3) to the inside by the directional tagging pulling insertion of driven pulley (26) and guiding rope sheave (41) or the inserted link (39) of disconnected rope safety guard; making simultaneously bolt (28) drive slip arm-tie (30) sliding tie rod (32) moves up; because the leverage of sliding tie rod (32) makes strap of the brake body (35) inwardly draw main limb guide track (22) surface that the strap of the brake (36) leaves standard knot (3) in, this moment cage (5) but non-resistance ground on the guide track that is linked to be by several standard knots (3), move.
When haulage cable (21) when rupturing suddenly; movable pulley frame (15) on the cage crossbeam (29) is owing to the pulling function of extension spring (24) makes it to set back rapidly; at this both sides safety device concurrently-acting: tension spring (43) the pulling inserted link (39) that is fixed on the cage crossbeam (29) inserts in the web member of standard knot (3), plays the safety guard-safeguard effect moment.The pressure spring (38) that is fixed on lock body frame (31) lower end moves arm-tie (30) pulling downwards simultaneously because the leverage of sliding tie rod (32) makes lock joint body (35) strap of the brake (36) tensioning of expanding and the main limb guide track of standard knot (3) (22) laterally; the downward more slippage of cage (5); expanding force is big more; cage (5) is checked firmly, resolved the rope purpose of protection automatically thereby reach.The principle of work of the push-and-pull safety door (14) of building hoist is: when cage (5) need select the stopping time at lifting process, safety door (14) can be drawn back, drop on attached wall bar (4) even go up the loose or fracture of haulage cable this moment, cage can not fall yet, thereby has guaranteed safe operation.
The utility model building hoist mainly solves following several technical matterss:
1. the cage of vertical transport operation, past is because the rack winch steel rope ruptures suddenly, braking brake is malfunctioning, cage falls immediately, cause physical damage and human casualty accident, safety device described in the utility model has solved the unexpected fracture of elevator steel rope in service, cage moment self-actuating brake is not fallen cage, thereby has guaranteed the safety of the machinery and the person.
2. need select the stopping time when cage, if sliding door open drop on can guarantee on attached wall bar and the high hand lever cage wireless be that the situation of traction falls.
3. owing to setting up of building hoist is that rising along with building changes rising, and require body can framework or floor attached to every one storey building on, so need not to socket cable wind rope, guaranteed that body has enough rigidity and stability.
4. passing by installation, the dismounting of old-fashioned building hoist all needs other elevator machinery to assist to finish, and it is limited that the height that sets up is installed, and erected cost is bigger, and the fabricating yard requires big.
The utility model adopts suspension rod, chain block to finish to have solved building hoist installation, rising and the dismantlement work expense is lower and antenna height is higher.
