Abstract
The utility model provides a power-driven chain block cascading lifting device. Large-scale hoisting machinery is required in the construction of multilayer and high-rise building roofs, but the scheduling is extremely difficult in the site crossed construction because of a narrow construction site. The power-driven chain block cascading lifting device comprises a left hold pole (1) and a right hold pole (2), wherein the left hold pole is connected with a left power-driven guide chain (3), the left power-driven guide chain is connected with a group of guide chains (4), the right hold pole is connected with a right power-driven guide chain (5), the right power-driven guide chain is connected with a group of guide chains, the left power-driven guide chain is connected with the right power-driven guide chain through a controller (6), and the lower end of each guide chain is connected with a hanging hook. The device provided by the utility model can be used for lifting heavy object.
Description
Technical field:
the utility model relates to a kind of later-model jack stringer, is specifically related to a kind of electronic jack serial connection bont.
Background technology:
When
multilayer and skyscraper roofing construction, need large scale hoisting machinery, and this moment on-the-spot crossed construction, the place of production is narrow, the scheduling difficulty very big.
To the engineering actual conditions, this builds maximum 3 tons of the liter weights that rise of tower crane that former civil engineering unit adopts
.And employing self-propelled hydraulic truck crane; Calculating palpus use rated load weight according to radius of turn (car position, the suitable station of main building distance is above 46 meters) and lifting altitude (adding that the front adds layer and step above 49 meters) outward is 250 tons large-scale crane, and crane arm at least must 76 meters.The price of a machine-team is 25000 yuan, even eight foldings are also wanted 20000 yuan, each ton steel structure will increase by 4000 to 5000 yuan of costs.The low temperature effect mechanical efficiency also has considerable influence for safety of operation still more.Construction unit has vetoed the scheme of civil engineering unit.
Summary of the invention:
The purpose of
the utility model provides a kind of can significantly reducing the cost, and is the electronic jack serial connection bont that can substitute large-scale construction equipment under certain execution conditions.
Above-mentioned purpose realizes through following technical scheme:
a kind of electronic jack serial connection bont; Its composition comprises: left pole, right pole, described left pole connect the electronic chain of leading in a left side, and a described left side is electronic leads chain and connect one group and lead chain; Described right pole connects the right electronic chain of leading; The described right side is electronic leads chain and connects one group and lead chain, and the electronic chain of leading in a described left side connects the right electronic chain of leading through controller, and the described chain lower end of leading connects hanging hook.
described electronic jack serial connection bont, described left pole and described right pole all have one group of solid drawn pipe to be formed by connecting.
Beneficial effect:
1. the utility model can promote the use of other field.Material facility vertical transport when keeping in repair like high level.
the utility model safety, reliable, economical and effective.Can also reduce labour intensity.Because power is conventional power supply, the influence of low temperature is smaller.So field of application is general, there is not any restriction in the use.
the utility model has been simplified construction organization, in the past with crane need the commanding at least must four-player (by roof, ground, the crane, installation site).This product can reduce commanding two people, is convenient to commander, and without crane, operation field focuses on an indoor place, significantly reduces safety hazard.
the utility model is compared saving mechanical stage student contributions pooled to pay for class activities per ton more than 4000 yuan with using wheel crane; Can save 40,000 yuan for 10 tons, 100 tons can reach 400,000 members; And the also corresponding reduction of labour cost.
the utility model is applied in to amount in the engineering wherein accomplishes 158 tons of liftings; Deduct more than 50 ten thousand yuan of the expense cost-cuttings of electronic jack; Both solve the technical barrier in civil engineering and the owner construction, reduced investment to the owner again.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
a kind of electronic jack serial connection bont; Its composition comprises: left pole 1, right pole 2, and described left pole 1 connects the electronic chain 3 of leading in a left side, and a described left side is electronic leads chain 3 and connects one group and lead chain 4; Described right pole 2 connects the right electronic chain 5 of leading; The described right side is electronic leads chain 5 and connects one group and lead chain, and the electronic chain 3 of leading in a described left side connects the right electronic chain 5 of leading through controller 6, and described chain 4 lower ends of leading connect hanging hook 7.
Embodiment 2:
Embodiment 3:
Installation method:
1, one tool only son and heir pole respectively is set at two ends, roof truss installation site, sunlight hall.Pole is φ 159 * 6 solid drawn pipes, long 5m.Can satisfy 8 tons of hoisting capacities.The pole fixed form adopts anchor ear, and each fuses with pedestal (high 1 m, 600 * 600 reinforced columns) together up and down.
, on pole, hang electronic jack.The jack string that every end is 20m by two lifting altitudes hangs over together, and the operator is at pedestal next door control rising or falling speed.
, the chain of bottom jack is put into maximum security improvement length, controller and jack are fixed together, and power supply are broken off.Chain with the top jack is put into maximum security improvement length again.Accomplish the operation of the other end simultaneously.
, that prefabricated roof truss is transported into the hall is indoor, places the suspension hook below, after checking of dimensions, direction are errorless.As prescribed is connected with suspension hook.
, examination are hung.Confirm to confirm to change over to formal lifting by on scene commander behind the safe and feasible.
, the two ends operator plays roof truss at the uniform velocity evenly and rises to setting height(from bottom) under unified command.Start the electronic jack in top at first simultaneously, waited to be raised to the security row journey, during promptly total hoisting depth 1/2, PTO Power Take Off.Then with bottom jack power connection.Start the bottom jack and continue to hoist, until reaching setting height(from bottom).
, unload hook, dismounting jack, pole
