Abstract
The utility model relates to a hydraulic caging device, which belongs to the mechanical caging field. The utility model comprises a bolt, a large arm and a fixed guiding rail. The utility model is characterized in that the utility model also comprises a lever, wherein, one end of which is connected with an oil cylinder and the other end of which is connected with the bolt, and the oil cylinder. The utility model skillfully utilizes the simple lever mechanism to easily realize the coordination of the movement of the oil cylinder and the bolt, and the transmission and the amplification of force. The utility model has the advantages of simple and safe operation, cabinet whole mechanism, convenient design, fabrication, and maintenance, and low cost.
Description
Technical field
The utility model relates to a kind of mechanical stop limiter, particularly relates to a kind of big arm limit stoper of paver.
Background technique
Paver need lift big arm when walking, and during walking, the oil hydraulic cylinder that lifts big arm is in running order all the time, in order to address this problem, has designed the limit stoper of big arm.The big arm limit stoper of paver adopts forms such as latch, hook more on the current market, is generally mechanical spring drag hook or manual bolt, uses inconvenience, and dangerous.
Summary of the invention
The purpose of this utility model is to provide the big arm limit stoper of hydraulic pressure a kind of easy and simple to handle, safe and reliable.
In order to achieve the above object, the utility model hydraulic stop comprises latch, big arm, and fixed guide is characterized in that also comprising the lever that an end links to each other with oil cylinder the other end links to each other with latch, and oil cylinder.
As further improvement of the utility model, this hydraulic stop also comprises position limit switch.
Because the utility model has adopted the convenient type leverage, and is easy and simple to handle, safe and reliable, again because the utility model also comprises position limit switch, can realize interlock control, the indication of latch position makes this device more perfect, reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now 1 describe mode of execution of the present utility model in detail in conjunction with the accompanying drawings
Big arm limit stoper with paver is an example, as shown in Figure 1, whole position-limit mechanism comprises latch 4, big arm 1, fixed guide 2, oil cylinder 3, lever 6, oil cylinder 3 is rotationally connected by bearing pin and lever 6, the fulcrum 5 of lever 6 is near oil cylinder 3 ends, it is light and stretch out fast to be beneficial to the motion of latch 4, bearing pin links to each other by the slotted hole on the latch 4 with latch 4, slotted hole can guarantee that latch 4 does straight line motion all the time easily in fixed guide 2, limit the axial position of bearing pin with cotter pin, whole device moves in fixed guide 2 by the latch 4 of motion drive lever 6 the other ends of lever 6 one end oil cylinders 3, thereby realize the spacing of big arm 1, latch 4 supports big arm 1, makes the oil hydraulic cylinder that lifts big arm be in the state that does not stress, and can prolong the working life of oil hydraulic cylinder.By this easy leverage, realized transmission and the amplification of oil cylinder 3 easily with latch 4 motor coordinations and power.In the big arm limit stoper of paver, also be provided with position limit switch 7, utilize position limit switch 7 can well realize interlock control, the indication of latch 4 positions, promptly be in the state that stretches out, do not amplify arm 1 down at latch 4; State in that big arm 1 puts down does not stretch out latch 4, to avoid the mechanical deterioration of 4 of big arm 1 and latches.It is reliable that this device is improved more.Whole apparatus structure is small and exquisite, designs, makes simply, and easy to maintenance, cost is low.
Claims (2)
1 one kinds of hydraulic stop comprise latch (4), big arm (1), and fixed guide (2) is characterized in that also comprising that an end links to each other with oil cylinder (3), the lever (6) that the other end links to each other with latch (4), and oil cylinder (3).
2 hydraulic stop according to claim 1 is characterized in that this device also comprises position limit switch (7).
