Abstract
The utility model discloses a hydraulic lifter, which comprises a pulley base, an elevator and an operation table, wherein the operation table is positioned at the upper end of the elevator which is connected with the base and positioned at the upper end of the base. A hydraulic operation system and an electrical operation system which are matched with each other are disposed on the base. The hydraulic lifter is capable of travelling and lifting automatically, the operation table has a three-in-one function of horizontally pushing weights, and further, the hydraulic lift can realize lifting effectively and stably and is higher in safety and practicality.
Description
Technical field
The utility model relates to the auxiliary device that a kind of building engineering is used, and relates in particular to the hydraulic hoist of usefulness such as a kind of large bridge, high-flying highway.
Background technology
At present, because the needs of city planning and development, many buildings, bridge etc. need reconstruction, but wherein are no lack of the building that much still has very high value of service, rebuild the labor manpower and financial resources if torn open according to the conventional method.Therefore various jackings technology in construction trade, the displacement technology develops rapidly with the emphasis reinforcement technique, becomes and utilizes building, protects the state-of-the-art method of science of building.Certainly, applying to above-mentioned technology aspect the bridge construction reconstruction too.
The bridge jacking The Application of Technology is in the integraty of protection superstructure; The height of lifting bridge satisfies the navigation requirement, and very important meaning is arranged, and it had both saved the cost of investment; Shortened the duration of construction again, little to the pressure influence of traffic.
Certainly except in the process of jacking; Elevator often is used in other engineering items that need climb, yet existing elevator mostly can not be walked and can only be moved; And can carry on the platform that goes up and down and the function of mobile object does not possess basically; Be to be very inconvenient in the carrying out of engineering, the progress of influence construction has increased the difficulty and the imperfection of construction.
In sum, along with the construction of increasing heavy construction needs, a kind of invention new, that be fit to the hydraulic hoist of the safety that jacking uses specially is imperative.
The utility model content
The purpose of the utility model is to overcome the deficiency that elevator in the prior art exists--inconvenience walking, not all over moving object etc., provide a kind of new, be fit to the hydraulic hoist of the safety that jacking uses specially.
The utility model provides a kind of hydraulic hoist that can be used in large bridge jacking engineering, and the completion jacking safe smoothly for large bridge provides safeguard.
The hydraulic hoist that the utility model adopted is a kind of multiduty hydraulic pressure car, and the outstanding feature of comparing with plain type (can only go up and down) hydraulic pressure car is that walking is certainly gone up and down, and has the three-in-one function that level promotes weight on the platform.
The purpose of the utility model realizes through following technical scheme:
A kind of hydraulic hoist is characterized in that, it comprises: the belt wheel base is connected companion ladder that is positioned at the base upper end and the platform-bench board that is positioned at the companion ladder upper end with base.
Said base is provided with the electrical installation system of hydraulic system and cooperation.
Said hydraulic system comprises hydraulic ram, the electrical motor that power is provided, with the electrical bonded assembly gear type pump of electrical motor, and the electromagnet bearing valve that transmits and carry out power, and accessory equipment oil pressure indicator and high-pressure rubber pipe.
Said hydraulic hoist comprises electric up-down switch and two kinds of up-down modes of hand-operated lifting knob.
It is range upon range of that said companion ladder is the X type.
The relative prior art of the utility model has the following advantages and beneficial effect: it can go up and down from walking, has the three-in-one function that level promotes weight on the platform; It is pulsation-free realization up-down effectively, and safety is higher, and practicality is stronger.
Description of drawings:
Combine the description of its accompanying drawing through following embodiment, can further understand and use later-model purpose, specific structural features and advantage in fact the utility model.Wherein, accompanying drawing is:
Fig. 1 is the hydraulic system principle scheme drawing of the utility model hydraulic hoist;
5, gear type pump, 4, electrical motor, 3, the electromagnet bearing valve, 2, oil pressure indicator, 1, high-pressure rubber pipe
The specific embodiment:
Below in conjunction with the instance among the figure the utility model is done further to describe.
The utility model hydraulic hoist is a kind of multiduty hydraulic pressure car, and the outstanding feature of comparing with plain type (can only go up and down) hydraulic pressure car is that walking is certainly gone up and down, and has the three-in-one function that level promotes weight on the platform.
The utility model hydraulic hoist comprises the belt wheel base, is connected companion ladder that is positioned at the base upper end and the platform-bench board that is positioned at the companion ladder upper end with base.Said base is provided with the electrical installation system of hydraulic system and cooperation.As shown in the figure, said hydraulic system comprises the electrical motor 4 that power is provided, with the gear type pump 5 that electrical motor 4 electrically connects, the electromagnet bearing valve 3 that transmits and carry out power, and auxiliary oil pressure indicator 2 and high-pressure rubber pipe 1.Said electrical installation system comprises some switches and valve and the indicator lamp etc. that electrically connect with electrical motor 4.
Said hydraulic hoist comprises electric up-down switch and two kinds of up-down modes of hand-operated lifting knob.Said electric up-down switch comprises the rising button and the decline button of crawl, and crawl is pinned rising and the step-down operation that corresponding button just can be realized elevator respectively, with this operation that utilizes the operator's station of companion ladder top to respond.
It is range upon range of that said companion ladder is the X type, and range upon range of number of times can increase as required, but the whole drive that can not surpass hydraulic actuating cylinder and electrical motor; The range upon range of companion ladder of said X type can be realized the angle tilt of operator's station and then the article carrying on the realization operator's station etc.
During use, carry out basic operation according to following steps:
1. energized (attention hand of rotation).
2. energized switch (use key).
3. promptly rise by rising button (crawl) elevator, be raised to the desired height position.
4. drop to desired height until original position by decline button (crawl).
5. if need on bench board, to operate, must on the bench board panel block, stir change-over swith (bench board).Operating sequence is identical with the chassis operation.
6. for guaranteeing elevator service life, take the special messenger to operate as far as possible, keeping.
7. when elevator rises, oil pump work; During decline, electromagnetic valve work.
8. elevator is forbidden on the gradient, to use.
Those of ordinary skill in the art will be appreciated that; Above embodiment only is the purpose that is used for explaining the utility model; And be not with the qualification of doing the utility model; As long as in the essential scope of the utility model, in the scope to the variation of the above embodiment, claim that modification all will drop on the utility model.
