Description
Technical field
The utility model relates to a kind of Foldable overhaul test cart, belongs to electrical equipment Work tool field.
Background technology
In electric system, it is larger that the checking experiment such as high-potting, protective calibration for associate power equipment is operated in proportion shared in daily power transformation maintenance work.And current checking experiment personnel are when carrying out checking experiment work to relevant device, all test apparatus equipment is placed on the ground near Awaiting Overhaul equipment, checking experiment personnel adopt semi-crouch or full crouching posture to complete the operation such as wiring, control to instrument and equipment, like this instrument and equipment is placed in ground, experimenter adopts semi-crouch or full checking experiment operating mode of squatting, cause operated by personnel's inconvenience, personnel's fatiguability, be unfavorable for safety in production.And, in order to shorten power off time, current substation often adopts multi-compartment to concentrate maintenance mode, the checking experiment work of multiple equipment is carried out together, longevity of service, and the placement location of checking experiment instrument and equipment is moved by staff along with the conversion of intertrial interval, work capacity is caused to strengthen, reduce work efficiency, extend power off time, also easily cause the omission of test Work tool.In addition, the placed angle of some test apparatuses, table meter has the strict requirement error of such as most test facility and the level angle (can not more than 5 °), some substation testing ground ground unfairness, experimental instrument and equipment being directly positioned over ground may cause the placement of instrument and meter undesirable, causes the problem such as experimental result accuracy, reliability reduction.These have become restriction checking experiment work efficiency and the problem of can not ignore such as safety, reliability.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned existence, and the Foldable overhaul test cart providing a kind of structure simple, easy to use.
The utility model is achieved by the following technical solution: described Foldable overhaul test cart, it mainly comprises dolly test platform, column, expansion Locking Device, cart base plate and little pulley sheave, described cart base plate bottom is fixed with four little pulley sheaves, four root posts are connected between cart base plate and dolly test platform, every root post passes through together with screw rod or hinge with lower pillar stand by upper pillar stand, and the hinged place of upper pillar stand and lower pillar stand is provided with expansion Locking Device.
The upper end thereof of described upper pillar stand in dolly test platform, the lower end of lower pillar stand and cart base plate and corresponding little pulley sheave hinged; The folding stow lock locking apparatus for column is provided with in the middle part of described cart base plate side.
The expansion Locking Device of the hinged place setting of described upper pillar stand and lower pillar stand is made up of the upper pin that can be serially connected on hinged place upper pillar stand and lower pillar stand in respective pin hole; The folding stow lock locking apparatus be made up of the lower bearing pin that can be serially connected on cart base plate side and column in respective pin hole is provided with in the middle part of described cart base plate side.
The features such as it is simple that the utility model has structure, easy to use; It is on-the-spot that it is applicable to maintenance of electrical equipment experimental work in electric system preferably, substantially increases the work efficiency of electric system checking experiment, safety and reliability.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1-4, Foldable overhaul test cart described in the utility model, it mainly comprises dolly test platform 1, column 2, launch Locking Device 3, cart base plate 4 and little pulley sheave 6, described cart base plate 4 bottom is fixed with four little pulley sheaves 6, four root posts 2 are connected between cart base plate 4 and dolly test platform 1, every root post 2 by upper pillar stand 21 and lower pillar stand 22 by screw rod or bearing pin 23 hinged, and the hinged place of upper pillar stand 21 and lower pillar stand 22 is provided with expansion Locking Device 3.
The upper end thereof of described upper pillar stand 21 in dolly test platform 1 bottom, the lower end of lower pillar stand 22 and cart base plate 4 and corresponding little pulley sheave 6 hinged; The folding stow lock locking apparatus 5 for column 2 is provided with in the middle part of described cart base plate 4 side.
The expansion Locking Device 3 of the hinged place setting of described upper pillar stand 21 and lower pillar stand 22 is made up of the upper pin that can be serially connected on hinged place upper pillar stand 21 and lower pillar stand 22 in respective pin hole 31; The folding stow lock locking apparatus 5 be made up of the lower bearing pin that can be serially connected on cart base plate 4 side and column 2 in respective pin hole 51 is provided with in the middle part of described cart base plate 4 side.
Embodiment: see Fig. 1, a kind of Foldable overhaul test cart, it is primarily of dolly test platform 1, column 2, expansion Locking Device 3, cart base plate 4, the folding composition such as stow lock locking apparatus 5, little pulley sheave 6.
At Electrical Equipment for Substation checking experiment, when particularly concentrating maintenance, when using this Foldable overhaul test cart, the dolly being now in complete folded state is carried to checking experiment work-site, be placed on suitable work place, open the folding stow lock locking apparatus 5 being positioned at cart base plate 4 side, and launch dolly, two parts up and down of column 2 are made to be in vertical state, and operation launches Locking Device 3, make the upper and lower two parts junction of column keep stationary state in the course of the work, side schematic view when dolly launches as shown in Figure 2.Be placed on dolly test platform 1 by the test apparatus equipment of the current needs of work, staff's test wire connected between tested electrical equipment and test apparatus equipment just can stand on Plantago minuta operational test instrument and equipment and carry out experimental work.When needs transfer work place, other subsidiary experiment Work tool can be placed on cart base plate 4, promote little pulley sheave 6 and rotate, with Foldable overhaul test cart, instrument and equipment and subsidiary experiment Work tool be transferred to new test point ground.After experimental work terminates, after being cleaned out by article on dolly test platform 1, cart base plate 4, remove and launch Locking Device 3, operation column about 2 two parts junction is rotated inside dolly, make it fold, the semi-collapsed condition of Foldable overhaul test cart as shown in Figure 3.When dolly is in complete folded state, as shown in Figure 4, dolly test platform 1 and cart base plate 4 are in the state of being close to substantially, operate the folding stow lock locking apparatus 5 be positioned in the middle part of cart base plate 4, dolly test platform 1 is locked on cart base plate 4.The carrying of dolly can be facilitated like this, and reduce Foldable overhaul dolly and taken up space in handling process.
