Abstract
The utility model discloses a hydraulic pulling tool with a length-adjustable ejector rod in the field of pulling tools. The hydraulic pulling tool comprises an oil cylinder, wherein a support is fixed on a side wall of the oil cylinder, a connecting plate is hinged on the support, the connecting plate is hinged with a hook, and connectors are arranged on an extended end of the oil cylinder. The extended length of the extended end of the oil cylinder can be adjusted through increasing or decreasing the connectors, and the hydraulic pulling tool can be used for disassembling various fastening parts such as belt pulleys, bearings and the like.
Description
Technical field
The utility model relates to a kind of horse of drawing, and particularly a kind of hydraulic pressure draws horse.
Background technology
Draw horse also to claim tall and straight device, extensively apply to dismantle axles such as various shaft couplings, gear, bearing, belt pulley and tighten part, it is made of with the hook two parts that are connected (or hinged) with push rod push rod, push rod is divided into screw rod and two kinds of forms of jack, and hook is divided into two pawl formulas and three and grabs two kinds of formulas, catches the object that draws with hook during use, rotary screw formula push rod or eject the jack push rod, push rod is steadily advanced forward, and hook is corresponding to be retreated, being drawn object to pull out.
There is a kind of hydraulic pressure to draw horse in the prior art, comprise the bearing that is fixedly installed on the oil cylinder sidewall, be hinged with connecting plate on the bearing, connecting plate and hook are hinged, hook is provided with a plurality of circular holes, when the apparatus that draws horse to vary in size, when the external part outreach of oil cylinder is not enough, generally solve by the position of adjusting the pin joint on the hook for dismounting.
Its weak point is: this regulative mode takes time and effort, and long-term the adjusting has wearing and tearing to the hook pin joint, thereby influences the stability of hook, processes this type of and draws horse owing to need to offer hinge hole on hook more, thereby increased production cost.
The utility model content
The purpose of this utility model is to provide a kind of push rod length adjustable hydraulic pressure to draw horse, makes the outreach of external part of its oil cylinder that extended, during apparatus that dismounting varies in size, simple to operate easily.
For solving above technical problem, a kind of push rod length adjustable hydraulic pressure provided by the utility model draws horse, comprises oil cylinder, be fixed with bearing on the oil cylinder sidewall, be hinged with connecting plate on the bearing, connecting plate and hook are hinged, and the external part of oil cylinder is provided with connector.
In the utility model work, when needs are dismantled the apparatus that varies in size, only need to increase or reduce the quantity of connector, thereby the adjusting of break-in the external part outreach of oil cylinder, compared with prior art, the beneficial effects of the utility model are: this type of is easy to adjust, operates simple and easyly, has saved the labour.The utility model can be used in the dismounting of fastenings such as all kinds of belt pulleys, bearing.
As improvement of the present utility model, described connector has a plurality of, is concavo-convex connection between the connector.Further simplified the operation that increases or reduce connector.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 oil cylinder, 1a push rod, 2 bearings, 3 connecting plates, 4 connectors, 5 hooks.
The specific embodiment
A kind of push rod length adjustable hydraulic pressure as shown in Figure 1 draws horse, comprises oil cylinder, is fixed with bearing on the oil cylinder sidewall, be hinged with connecting plate on the bearing, connecting plate and hook are hinged, and the external part of oil cylinder is provided with a plurality of connectors, are concavo-convex connection between the connector.
In the work, when apparatus that needs dismountings varies in size, only need to increase or reduce the quantity of connector, thus the adjusting of break-in the external part outreach of oil cylinder, realize dismantlement work; Feasible increase of concavo-convex connection or the work of minimizing connector are convenient between the connector.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
