Background

At present, in the construction process of installing projects inside a standard factory building or a civil building underground parking lot, a large number of fire-fighting pipelines, smoke-proof and exhaust air ducts, electric bridges, siphon rainwater pipelines and the like are arranged at the top of a structural layer. In the construction process, a crane, a movable lifting platform or a forklift can be selected, and the heavy objects can be lifted by manpower directly or manually. However, the following problems may occur: 1. the ordinary crane with narrow space can not be completed, and the smallest crane in the market at present can not be met. 2. The self weight of the movable lifting platform is very large, and the movement is not very convenient. 3. The movable lifting platform has a certain height and can not directly lift heavy objects from the ground. 4. The mobile lifting platform has high leasing cost. 5. The self weight of the forklift is larger, and the forklift can only meet the use requirement of a first floor (tightly attached to the ground), and if the forklift is a floor layer, the floor can not meet the weight load of the forklift. 6. The method has the advantages of pure manpower, high danger, high labor cost and low efficiency.

Disclosure of Invention

The utility model discloses the technical problem that needs to solve is: in the construction process of the internal installation engineering of the underground parking lot of a standard factory building or a civil building, a fire fighting pipeline, a smoke exhaust prevention air duct, an electric bridge frame, a siphon rainwater pipeline and the like are complicated, a crane, a movable lifting platform, a forklift or direct manpower can be selected to complete the lifting of the heavy objects, but the methods have various problems, the high efficiency and the low cost cannot be achieved, and a high-efficiency and low-cost lifting tool is urgently needed.

The utility model aims at providing an indoor hoisting tool can effectively improve the installation effectiveness, reduces installation cost.

The utility model discloses a following technical scheme realizes:

the utility model discloses a convenient removal and the not hoisting of co-altitude of satisfying set up the pipe leading truck, set up on the pipe that the interval is 200 mm's locating hole 3, and the pipe davit is than the little model of pipe leading truck, just can penetrate the pipe leading truck, and the pipe davit sets up the interval and is 100 mm's locating hole 6, and the pipe davit can design different length as required. During operation, different heights can be realized according to the depth of inserting the pipe leading truck into the height-adjusting davit, and it is fixed to penetrate the round steel in the leading truck and the corresponding locating hole of davit simultaneously. The utility model discloses lift by crane and adopt low-speed hoist engine, wire rope links to each other with the lifting hook through bottom and top direction fixed pulley. The utility model discloses a convenient removal sets up 4 plastic universal wheels, can remove wantonly, and the universal wheel is from taking the brake, and the brake must be stepped on when lifting by crane the heavy object and dies. The utility model discloses for balanced focus during hoist and mount, set up the weight box, can put sand or square brick counter weight in the case, be convenient for draw materials on the spot, quantity and hoist and mount weight have the relation. The utility model discloses an appearance and size can be adjusted according to the weight and the promotion height of hoist and mount thing, but structure and principle are unchangeable.

Has the advantages that: the utility model discloses a lifting device mechanism is simple, convenient operation, is particularly suitable for the installation work of indoor engineering ceiling, can effectively improve the installation effectiveness, reduces installation cost.

Drawings

FIG. 1 is a schematic view of the present invention;

in the figure: the device comprises the following components, by weight, 1-universal wheel, 2-push handle, 3-weight box, 4-low-speed winch, 5-base guide fixed pulley, 6-support frame, 7-base, 8-lifting hook, 9-front support frame, 10-guide round pipe frame with positioning hole, 11-lifting arm with positioning hole, 12-upper guide fixed pulley and 13-steel wire rope.

Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein the shapes, structures, mutual positions and connections of the components, and the operation principle of the components are described in detail. The utility model discloses a base, weight box, low-speed hoist engine, direction fixed pulley, support frame, lifting hook, preceding support frame, take locating hole direction pipe support, take the pipe davit of locating hole, upper portion direction fixed pulley, wire rope. The utility model discloses a base, weight box, direction fixed pulley, support frame, preceding support frame, take locating hole direction pipe support adopt rigid connection as a whole, can not cut apart. The bolt fixing for the winch is detachable. The circular tube suspension arm with the positioning hole and the upper guide fixed pulley are integrated and are installed according to the corresponding positions when in use. Before the heavy object is lifted, the lifting appliance assembles all the components according to the requirements of the drawing. When the heavy object is lifted, the brake of the four universal wheels is stepped down after the lifting appliance is in place, so that the stability is ensured. The utility model discloses for balanced focus during hoist and mount, put sand or square brick counter weight in the weight box, draw materials on the spot, quantity and hoist and mount weight have the relation. When the heavy object is lifted, different corresponding positioning holes are adjusted according to the height of the heavy object, and when the lifting height can be met, round steel is inserted into the positioning holes, threads are arranged on two ends of the round steel, and the round steel is locked by nuts. When the lifting appliance walks and has an obstacle, the round steel in the positioning hole can be firstly pulled out, the height of the lifting arm is reduced, and when the lifting appliance is lowered to the minimum and still cannot meet the requirement of walking, the whole lifting arm is dismantled.
