Abstract
The utility model relates to a movable vertical hydraulic jack, which belongs to the technical field of lifting devices. The movable vertical hydraulic jack comprises a base and is characterized in that a wheel cavity is formed on the base, wherein a wheel is arranged in the wheel cavity, a compression spring is sleeved on the wheel, a forked nut penetrates a through hole on the base to extend into the wheel cavity and is connected with a wheel shaft of the wheel. The vertical hydraulic jack has the advantages of simple structure and low cost; the vertical hydraulic jack can move under the condition without load and can be pushed when being aligned with the lifting position, the load force is transferred to the compression spring under the load condition, the wheel can be automatically contracted into the wheel cavity under the compression action of the spring, and the wheel is contracted in the height of the bottom surface of the base when a certain load exists, therefore, not only the wheel is not damaged, but also the vertical hydraulic jack is labor-saving, convenient to use and high in efficiency.
Description
Technical field
The utility model belongs to the lifting device technical field, is specifically related to a kind of movable vertical type hydraulic jack, is the improvement to existing large-tonnage vertical hydraulic jack base structure.
Background technology
Large-tonnage vertical hydraulic jack can be widely used in departments such as factory position warehouse, bridge, harbour, communications and transportation and building engineering.Large-tonnage vertical hydraulic jack on the market is because heavy, mobile inconvenient now, and the client is heavier when using this type of jack to move, and then difficulty is bigger if will aim at the position that hoists in use.The client need move it desired location by means of other accessory appliances, when arriving desired location and will aiming at when hoisting the position, require great effort more owing to can't become by accessory appliances, and efficient is very low.At above-mentioned existing problems, also there is not ideal method to be solved in the market.
Summary of the invention
Task of the present utility model is to provide a kind of simple in structure; use not only laborsaving but also movable vertical type hydraulic jack easily; it can move when zero load; when hoisting the position, aligning can promote; and wheel can be retracted in the base end face height in load or when load is arranged, thereby can effectively protect wheel injury-free.
Task of the present utility model is finished like this, a kind of movable vertical type hydraulic jack, comprise base, be characterized in: on described base, be formed with the wheel chamber, in described wheel chamber, be provided with wheel, on described wheel, be arranged with compression spring, probe in the described wheel chamber and behind the through hole of a fork-shaped nut on passing described base and be connected with the wheel axle of wheel.
In a specific embodiment of the present utility model, the quantity in described wheel chamber be at least one or more than one, correspondingly, the quantity of described wheel, compression spring and fork-shaped nut is corresponding with the quantity in described wheel chamber.
In another specific embodiment of the present utility model, the quantity in described wheel chamber is preferably four, and the four wheels chamber is evenly distributed on four corners of base.
In another specific embodiment of the present utility model, constitute between the wheel axle of described fork-shaped nut and wheel and be threaded.
In another specific embodiment of the present utility model, described wheel is the ball wheel.
The utility model is because after adopting said structure, one of advantage that has, simple in structure, and cost is low; Advantage two, when zero load, can move, when hoisting the position, aligning can promote, and when load, be delivered on the compression spring by load force, utilize compression of spring to shrink wheel in the wheel chamber automatically, wheel has been retracted in the base end face height when certain load is arranged, so neither damage wheel, and use laborsaving, convenience, and the efficient height.

Among the figure: 1. fork-shaped nut; 2. base, 21. wheel chambeies, 22. through holes; 3. compression spring; 4. wheel, 41. wheel axles.
The specific embodiment
For the inspector that the makes Patent Office especially public can be expressly understood technical spirit of the present utility model and beneficial effect more, the applicant general elaborates in conjunction with the accompanying drawings in the mode of embodiment below, but to the description of embodiment all is not restriction to technical solutions of the utility model, any according to the utility model design done only for pro forma but not substantial equivalent transformation all should be considered as the technical solution of the utility model category.
See also Fig. 1 and in conjunction with Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of movable vertical type hydraulic jack, comprise base 2, on described base 2, be formed with wheel chamber 21 and through hole 22, the quantity in described wheel chamber 21 be at least one or more than one, in the present embodiment, preferred quantity is four, four wheels chamber 21 is evenly distributed on four corners of the base 2 of rectangular shape, the quantity of described through hole 22 also is four, four through holes 22 correspond respectively to the top in four wheels chamber 21, and communicate with wheel chamber 21.Be provided with a wheel 4 in each wheel chamber 21, the centre of wheel 4 has extended wheel axle 41, and the version of described wheel 4 is not subjected to any restriction, is preferably the ball wheel in the present embodiment.Be arranged with compression spring 3 on the described wheel 4, fork-shaped nut 1 probes into behind the through hole on passing base 2 22 downwards from the last plane of base 2 in the described wheel chamber 21 and is connected with wheel axle 41 on the wheel 4.Connection mode between the wheel axle 41 of described fork-shaped nut 1 and wheel 4 is not subjected to any restriction, in the present embodiment, is preferably and is threaded.
See also Fig. 3, planar structure cutaway view when Fig. 3 withstands on zero load for the utility model hydraulic jack, under this state, compression spring 3 is given 3 one application forces of compression spring by the deadweight of jack self, compression spring 3 is given antagonistic force of jack, and this antagonistic force overcomes jack gravity and the jack jack-up that makes progress, makes wheel 4 expose the bottom surface of base 2, like this, can realize moving or promoting by wheel 4 to jack.
See also Fig. 5; planar structure cutaway view when Fig. 5 withstands on load for the utility model hydraulic jack; under this state; external force is given 3 one application forces of compression spring; compression spring 3 is given antagonistic force of jack; compression spring has certain forced stroke; when load surpasses certain load; it is in the base end face height that compression spring 3 is retracted in the wheel chamber 21 of base; this moment, the base end face by jack contacted with ground; and between wheel and the ground just point contact and do not play a supportive role, thereby can effectively protect wheel 4 not to be damaged.
The utility model makes wheel stressed even at each position owing to four corners that four wheels 4 are evenly distributed on the jack base bottom, and jack is not steadily turned on one's side in moving process.
