Abstract

The utility model discloses a forklift-type jack, which comprises a jacking piece and a jacking rod and is structurally characterized in that the upper end of a material shovel is arranged on the jacking rod and near the upper end of the jacking rod. The forklift-type jack can be used in the earthquake first aid under the no-power condition; under the circumstance that buildings fall, floor slabs can be shoveled by the material shovel, and building beams can be jacked by the jacking rod of the jack; the forklift-type jack is used as a vehicle repair tool in the departments of factories and mines, communications and transportation and the like, and the jack not only has the jacking function but also has the shoveling function, has flexible and reliable hoisting and can be carried and operated by a single person; however, the material shovel can be detached when being not needed and can be installed when being needed. The forklift-type jack has the function of dual purposes on one machine.

Description

A kind of fork truck formula jack

Technical field:

The utility model relates to a kind of fork truck formula jack.

Background technology:

Existing jack can be divided into 3 kinds of rank-and-pinion jack, spiral (machinery) jack and hydraulic pressure (oil pressure) jacks by architectural feature.

1. rank-and-pinion jack: lift part by lever and gear driven tooth bar as the top by manpower and promote thick stick top, top and lift heavy thing.Hoisting capacity generally is no more than 20 tons, can support weight for a long time, and the place that mainly is used in the operating condition inconvenience maybe needs to utilize the claw of bottom to promote the occasion of weight, as railway rail lifting operation.

2. lifting screw: by the screw pair transmission, screw rod or ut socket are lifted part as the top and are promoted thick stick top, top and lift heavy thing by manpower, see shown in Figure 2ly, and common lifting screw 3 is supported weight by the screw thread self-locking action, simple structure, but driving efficiency is low, and return is slow.Do not have self-locking action from the screw thread that falls lifting screw, but drg is housed.The loosen the brake device, weight can descend voluntarily fast, shortens return trip time, but this jack structure is complicated.Lifting screw can be supported weight for a long time, and the biggest lifting capacity has reached 100 tons, uses wider.After horizontal screw bolt was loaded onto in the bottom, it was traversing to make weight do small distance.

3. hydraulic jack:,, lift part with cylinder body or piston as the top and promote thick stick top, top and lift heavy thing by the hydraulic efficiency pressure system transmission by manpower or driven by power Hydraulic Pump.Hydraulic jack can be divided into integral type and separation type.All-in-one-piece pump and hydraulic actuating cylinder join together; The pump of separation type separates with hydraulic actuating cylinder, and the centre links with high pressure hose.The hydraulic jack compact conformation, energy is the jacking weight steadily, 1000 tons of hoisting capacity up, 1 meter of stroke, driving efficiency is higher, so use wider; But easy oil leakage should not be supported weight for a long time.Need select the self-locking jack for use as long-term support, lifting screw and hydraulic jack are further to reduce height of contour or increase the top to lift distance, can make multi-stage telescopic.Hydraulic jack can repack climbing form jack, hydaulic lift platform, stretch-draw machine etc. into by same principle except that above-mentioned basic version, be used for various special construction occasions.

Thereby the jack of three kinds of structures all comprises the top and lifts part and top thick stick, and different is that part structure difference is lifted on the top, promotes top thick stick lifting and reaches the top and lift and weigh thing but lift part by effects such as manpower top; But existing jack structure does not have the fork truck function, for placing ground goods or object directly not to shovel from the bottom into making its lifting jack-up.

Summary of the invention:

The purpose of this utility model provide a kind of for place ground goods or object can directly shovel from the bottom into fork truck formula jack.

The purpose of this utility model is achieved in that described a kind of fork truck formula jack, comprises that the top lifts part and top thick stick, and its constructional feature is that the upper end of goods shovel is installed on the thick stick of top and is the position that is positioned near top thick stick upper end.

Advantage of the present utility model: the utility model is provided with the goods shovel on the thick stick of the top of existing jack, thereby reaches the effect that both has jack, the effect of in stockit is available shovel again; Adopt top thick stick jack-up for unsettled object or weight, for the object that lies on ground or the plane, adopt goods to scoop up, the top thick stick of jack is to lift the part effect by the top of the prior art of different structure to promote jack-up, and the top thick stick of jack is a synchronization lifting with the goods shovel that is arranged near top thick stick upper end; Fork truck formula jack of the present utility model can be in the earthquake first aid, uses not having under the electric situation, and under the situation that building falls, cement plate can scoop up with the goods of jack, and the building beam can be with the top thick stick jack-up of jack; Instrument in departments such as factories and miness, communications and transportation as Mechanical Help, existing jack-up function scoops up function again, the lifting flexibility and reliability, a people is portability and operation; But when not needing the goods shovel, can dismantle, can install when needing; Has the dual-use function.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a kind of structural representation of existing common lifting screw.

Among the figure: top thick stick 1, goods shovel 2, lifting screw 3, handle 4.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is elaborated:

As shown in Figure 1, a kind of fork truck formula jack described in the utility model, the structure that comprises existing jack, comprise top act part and top thick stick, can lift part work as dynamic actions such as effect handle 4 or oil pressure top by manpower and make the thick stick lifting of connected top, constructional feature of the present utility model is to be provided with the goods shovel on the thick stick of the top of existing jack, and is at close its upper end of top thick stick in stockit is available shovel to be installed; Be the close upper end that goods shovel upper end is installed in the top thick stick, the goods shovel is General Construction, general shape as the L type.

Claims

1. fork truck formula jack comprises that the top lifts part and top thick stick (1), and the upper end that it is characterized in that goods shovel (2) is installed in that top thick stick (1) is gone up and is the position that is positioned near top thick stick (1) upper end.
