JP3058213U - Jiga cylinder with solenoid valve for liftable car deck - Google Patents

Abstract

(57) [Summary] [Problem] To raise and lower a liftable car deck and, as a next operation, to operate a support device for holding the liftable car deck at a predetermined position, and to confirm the operation of the support device. Was performed by a limit switch, and a series of operations, in which the elevating device had to be in a neutral state, were performed manually. The number of operating and checking personnel was large, and the work efficiency was very poor. SOLUTION: An electronic valve is provided in a jig cylinder to perform lifting and lowering of a liftable car deck, operation of a supporting device, confirmation of operation of a supporting device, completion of a lifting operation and a series of operations using an electric signal. It is intended to be activated and to be automated.

Description

[Detailed description of the invention]

[0010]

[Industrial applications]

 The present invention relates to a lifting device for moving a liftable car deck to a predetermined position in a car carrier.

[0020]

[Prior art]

 As shown in FIG. 2, a main part of a liftable car deck 31, a so-called movable deck, includes a fixed deck 32, a supporting device (not shown), and a lifting device 33.

The lifting device 33 suspends a jigashi ringer 34 from the fixed deck 32 via an eye plate 35, and the jig cylinder 34 has pulleys 37 and 38 on the upper and lower sides, and at least four corners of the liftable car deck 31. The wires 361,362 to be suspended ... took between the pulleys 37 and 38 several times.

The piping 40 sent from a hydraulic unit (not shown) disposed on the fixed deck 32 is filled with hydraulic oil, and the fixed deck 32 is provided with a manual control stand 41. The hydraulic oil goes to the manual control stand 41 at a constant pressure, puts the lot 42 of the cylinder 39 in and out, and changes the distance between the pulleys 37 and 38 so that the wires 361, 362. Were carried out all at once, and the liftable card deck 31 was to be raised and lowered.

[0050]

[Problems to be solved by the invention]

 As described in the background art, the liftable car deck is raised and lowered, and as a next operation, a support device for holding the liftable car deck in a predetermined position must be operated. A series of operations were performed manually, requiring the operation switch to be checked with a limit switch and the lifting device to be neutral. There was a problem that the number of operating and checking personnel was large, and the work efficiency was extremely poor.

The present invention has been made in view of such insufficient points of the prior art, and aims at raising and lowering the liftable car deck, operating the support device, and controlling the support device. Since the operation confirmation, the end of the lifting and lowering operation, and the series of operations are all performed using electric signals, no human operation is involved, and the system can be simplified and the operation can be simplified.

[0070]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a lifter for a liftable car deck, in which the jig cylinder has pulleys on the upper and lower sides, and at least wires hanging at four corners of the liftable deck have a plurality of tracks between the pulleys. Then, a solenoid valve is attached to the jig cylinder, and the pipe is connected to the cylinder via the solenoid valve.

[0080]

[Embodiment of the invention]

 In this invention, a jig cylinder is equipped with a solenoid valve to perform the lifting and lowering of the liftable car deck, the operation of the supporting device, the operation confirmation of the supporting device, the completion of the lifting and lowering operation, and a series of operations using an electric signal. It works and tries to automate it.

【Example】

 As shown in FIG. 1, the main part of a liftable car deck 1, a so-called movable deck, is composed of a fixed deck 2, a supporting device (not shown), and a lifting device 3.

The lifting / lowering device 3 suspends a jigging ringer 4 from the fixed deck 2 via an eye plate 5. The jig cylinder 4 has pulleys 7 and 8 arranged vertically, and at least the four corners of the liftable car deck 1 are suspended. Wires 61 and 62 take a few times between the pulleys 7 and 8 several times.

Further, a pipe 10 sent from a hydraulic unit (not shown) provided on the fixed deck 2 is filled with hydraulic oil, and a solenoid valve 11 is attached to the jig cylinder 4. The oil pipe 10 is connected to the cylinder 9 via an electromagnetic valve 11.

012
The cylinder 9 switches the solenoid valve 11 by operating a remote switching button 13, inserts and removes the lot 12 of the cylinder 9, and changes the distance between the pulleys 7 and 8, thereby changing the wire 61. , 62... Were simultaneously pulled in and out, and the liftable car deck 1 was to be raised and lowered.

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. The idea of this invention is to provide a jig cylinder with a solenoid valve, which allows the lifting and lowering of the liftable car deck, the operation of the support device, the confirmation of the operation of the support device, the completion of the lifting and lowering operation, and a series of operations to all be performed using electric signals. Since no operation is included, the system can be simplified and operation can be performed safely with a small number of personnel.
