Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is, the vehicles rests, equilibrium same of vehicle mounting stand that Agekasane such as for servicing the automobile
It relates to a period method and apparatus, in particular to be able to hold the vehicle horizontally, to allow the lifting of the rise and fall, to their equilibrium synchronization method and apparatus to always be equilibrium operating the lift used.

[0002]

2. Description of the Related Art Conventionally, a mounting table or a lift table of an automobile and a method of operating the same are described in terms of a hydraulic circuit attached to a cylinder, a piston or a plunger (hereinafter, referred to as a cylinder) of a mounting table apparatus (hereinafter, referred to as a lift), and There is a related to ancillary equipment, and as described in Japanese Patent Application Laid-Open No. 52-135159, a hydraulic source having separate forward and reverse rotatable pumps is arranged on a lift that is divided into front wheels and rear wheels, A system which integrally controls the circuits in accordance with the difference in the load related to each lift. As described in Japanese Utility Model Publication No. Sho 57-18398 filed by the applicant of the present invention, the hydraulic oil There are proposals to eliminate the phenomenon of stagnation in the circuit and excessive burden on the seal structure in the used cylinder.

[0003] Further, instead of individually arranging the lifts as described above and mounting the vehicle, as shown in FIG.
Base 3 provided on the left and right so that the vehicle can be lifted integrally
The lift pillars 30a and 30b are provided at the center of the base 30 and the movable beams 31 to 33 are interposed between the bases 30 so as to be extendable and contractible so as to be mechanically integrated and lifted. There is a type in which the mounting plate 36 is configured to be able to extend in the vertical direction to simplify the lifting. Here, the arrow in the figure indicates the direction of entry and exit of the vehicle.

[0004] In this type of lift, how the lift of the vehicle is operated so as to maintain a horizontal state irrespective of the weight of the vehicle to be handled, or a step-like operation phenomenon does not occur when the lift is raised and lowered. Such an equilibrium operation was important. There should be no dangerous imbalances that would cause the vehicle to detach from the lift, but if the imbalance can be corrected as soon as the imbalance is visible, uneven load can occur. In addition to the vertical static load assuming the above, a situation that occurs intensively is dealt with by coping with the structural strength of the lift, and is dealt with by the operation system such as the hydraulic circuit described above. Therefore, the structure of the lift can sufficiently cope with the occurrence of a maximum load on the wheels or the mounting position of the mounted vehicle due to some inclination of the mounted vehicle.
After incorporating the bending moment and other design elements for strength calculation in addition to the vertical load, it was natural to determine the material selection and size of the member.

[0005]

However, when a lift for a vehicle is manufactured on the assumption of vehicles of various sizes, for example, a lift for a front wheel and a lift for a rear wheel are paired into one set. As shown in FIG. 2, the two lifts usually have different vehicle mounting positions, so they are not necessarily on the same horizontal plane, and it is difficult to set a pair of lift axes correctly by visual recognition, or This requires the operator to pay close attention to the operation, and therefore, the hydraulic circuit for balancing operation that lifts both lifts to satisfy the operation and at the same time is complicated, and the manufacturing cost for it is expensive, and furthermore, Considering the factors corresponding to the load change at the time of unbalance, the lift that determines the structure increases the cross-sectional area of the lift and increases its weight as the safety is dealt with. When the size of the pair of lift sets is configured to be variable according to the size of the vehicle, the variable structure of the lift that can be balanced is adapted to the unbalanced state. You have to be careful and oversize the structure. On the other hand, the lift can be generally stored in the pit, and the upper portion can perform other work when not in use. Therefore, it is desirable that the size of the pit is small, and that when the pit is not used, a part of the lift is not exposed on the floor as much as possible and does not hinder the work. In addition, the projected area of the lift itself must not be so large that the structure of the lift itself during use will not interfere with the maintenance of the vehicle. The lift shown in FIG. 7 represents a general problem of the prior art, its pits and its projected area are large, and the head of the lift pillar always projects above the floor, which is not a desirable example. That is, the prior art described above does not consider the nature of the load applied to the lifts deeply, and therefore analyzes the difference in the nature of the member stress acting on each member of each lift in the synchronous operation when lifting a pair of lifts. Without solving the problem of the balance operation of a pair of lifts by elucidating the nature of the stress without doing so, there has been no proposal of a lift balance synchronization method and apparatus that enables good vehicle maintenance. .

[0006] It is an object of the present invention to address the shortcomings of the prior art.
While simplifying the equilibrium lifting operation of the pair of lifts and adding means to increase the automation rate,
From the technical aspect that this prior art has not taken up, it is possible to perform equilibrium synchronization by interposing a parameter member in the lift structure, thereby making it possible to reduce the weight of the lift structure and to realize a safer vehicle mount. It is an object to provide a balanced synchronization method and apparatus .

By controlling the branch circuit side to correct more the torsion controllable hydraulic circuits a b (control unit), and wherein the pair of lift 5a, 5b is synchronized at all times so that the equilibrium Is what you do.

In detecting the displacement of the torsion, the displacement is converted into 1) the amount of rotation of the synchronous shaft, and the predetermined amount of rotation is twisted to the surface of the synchronous shaft using a strain stress gauge or the like. 3) Moire or change in potential difference of stress or pressure caused by the shaft material, which is caused by torsion on the surface of the synchronous shaft directly or indirectly through the sensitive material, and erases the detected amount. method of controlling the hydraulic circuit in a direction can be an embodiment of the present invention to select and determine suitable to Yichun.

[0014]

According to the above technical means, as in the prior art, it is also possible to design the vehicle by assuming various load factors to be applied to the lift, determine the lift structure, and make the lift operation highly dependent on visual recognition. Therefore, there is no need for the skill of the operator to perform the equilibrium synchronization operation, and when the operation process that requires the equilibrium operation of both lifts is started, the operation shown in FIG.
Particularly , the synchronous shaft is linked to the left and right lifts via the clutch, and when an unbalanced state occurs between the lifts in the integrated synchronous shaft as shown in FIG. The lift can be detected and controlled by operating the components of the hydraulic circuit so as to eliminate the generated torsion by the detection signal based on the detection result, so that the lift can be operated and managed to always receive only the vertical load. Therefore, it is not necessary to reinforce the lift structure including the cross section in consideration of other design factors, and therefore, the lift structure can be simplified, and can be reduced in size and weight. And
Since the synchronous shaft provided between the two lifts only needs to be able to present the twisting phenomenon on the detecting device side, the shaft does not need to have sufficient rigidity, and the shaft diameter may be small. Since the pair of lifts can be connected to the synchronous shaft by a flexible shaft on the detection device side, it is easy to arbitrarily and variably set the relative positions of the pair of lifts. Furthermore, since the visual recognition of the operator required for the lift operation is greatly reduced, and remote control is possible,
Labor saving, improvement of work environment and improvement of safety can be secured.

FIG. 4 is a hydraulic circuit diagram of an embodiment of the hydraulic circuit applied to the present invention. The hydraulic pressure supplied from the hydraulic source 20 is divided via a hydraulic pipe 14c so that the distribution of the oil amount can be precisely controlled. A valve 15 (e.g., trade name "De-Co-Valve" manufactured by Takami Seiki Co., Ltd.) is diverted to a mounting base that comes into contact with the vehicle via hydraulic solenoid valves 13a and 13b of branch pipes 14a and 14b. directly to the cylinder 8a, which form <br/> formed hydraulic circuits which communicate with the 8b. The cylinders 8a, 8b also engage with the detectors 7a, 7b of the detector 4, and the movement of the cylinders 8a, 8b enables the detectors 7a, 7b to operate.
When the detectors 7a and 7b are activated, the signals generated by the detectors can excite one of the control sides of the hydraulic solenoid valve 13 which cancels and corrects the displacement. The cylinder 8
The status of each cylinder arranged in can be held, and the holding release can air cylinder 2 1a, and 21b to the constant, it by the air source 29 through a required air circuit and is preloaded with a predetermined pressure . Although the above description has been made with reference to the circuit device that operates exclusively for raising, when the lift is lowered, the lift valve 17 in the figure is adjusted by exciting the lift valve 17 in the figure by a known means using an electric control circuit not described here.

5b shows a case of a combination suitable for a case where the operation can be performed horizontally from the initial state.

FIG. 6 is an overall plan view showing a second embodiment of the lift set to which the present invention is applied. Lifts 5c and 5d are arranged at right angles to the approach direction of the vehicle, and the lift 5d is connected to the axle distance Q. In maintenance of different vehicles, the synchronous shafts 1 and 3 are configured to be movable by the rail 34 to the position of the lift 5e and the lift set length can be set to K1 or K2, and / or the initial state of the lift is changed. The two lifts 5c,
The case of a suitable combination when the mounting stand position of 5d is different is shown. . As shown here, the fixed type or the flexible type of the synchronous shaft 3 can be freely selected depending on the arrangement state of the lift and its use.

Next, the principle and procedure of the balanced synchronization method of the present invention will be described mainly with reference to FIG. Each vehicle weight loading position of the pantograph mechanism lift (load
Position) , the lifts are lifted from the no-load state to the load state, and then the clutches 2 are connected and the synchronous shafts 1 and 3 are integrally lifted.
In the illustrated left (a) side lift the right side (b) riff
The shaft section 6A of the synchronous shaft 101A connected to the lift indicated by the two-dot chain line shows that the synchronous operation is performed as long as the lifting operation is performed in an equilibrium manner and the change in the height of the lift is equal. 101A only moves in parallel from the initial state position, and the position C1 of the initial horizontal line of the synchronous axis and the initial horizontal line C0 do not change.

However, when an unbalanced state of height G occurs between the lift on the right and the lift indicated by the solid line on the left as shown in the figure, the synchronous shaft 101A forms an axial section 101B. Changes occur. That is, the lifting is performed by the rotation of the oblique member 52b around the fixed shaft pin 56b as R, and the generation of the gap G of the lifting height between the two lifts means that the rotation angles of the two lifts are different. means. If the rotation angle is different, the synchronous shaft 101B integrated by connection
Is changed to the initial horizontal line C0 by displacing the position C1 of the initial horizontal line by the moving displacement amount e. That is, it means that the twist has occurred in the synchronous shaft 101B by the e displacement amount. This twisting behavior is detected, controlled in a direction to erase the e displacement, operating the hydraulic circuits mentioned above. Since the amount of twist e becomes smaller as the balancing operation is performed with higher accuracy, it is necessary to expand the detection amount. Since this amount of torsion occurs in the circumferential direction of the axial cross section, its detection requires that the detecting device can recognize the direction. An appropriate signal in that direction can be instructed to the control system.

The principle described above, the procedure has been described mainly in ascent, twisting phenomenon during descent generates, the twist detected by the detecting device, the generated signal to control the control system Is the same as the above procedure.
