The telescopic driving mechanism also comprises a middle rotating pin box translation mechanism, and an upper and a lower pushing rod locking hook devices. The middle rotating pin box translation mechanism comprises a translation hydraulic oil cylinder, lower pushing rods, connecting plates, an abrasion reducing block, and a limiting position limiting switch, the upper pushing rods are arranged on the both sides of the middle rotating pin box, the upper pushing rod on each side is respectively connected with a roller chain, the left and the right lower pushing rods are respectively connected with the two left and the right pairs of middle rotating pin boxes through the connecting plates, and the two left and the right lower pushing rods are respectively connected with a pair of translation hydraulic oil cylinders. The upper and the lower pushing rod locking hook devices comprise an upper and a lower pushing rod para position limiting devices, a locking hook oil cylinder, and a locking hook connected with the locking hook oil cylinder. The utility model can simultaneously perform the separating and collecting motion of two containers, to realize the hooking and unhooking of the telescopic mechanism and the locking hook device of the movable double-box hoist.
Description
Technical field
The utility model relates to the container handling crane tool, particularly a kind of telescoping mechanism of packaged type double-box hanger and latch hook device.
Background technology
Existing conventional design-calculated freight container double-box hanger has only a cover telescopic drive mechanism, it can only make the lock pin at end carriage place change the position, therefore can only load and unload the freight container of 20 feet, 40 feet or 45 feet, and 20 forty equivalent unit 40s of two fixed placement positions, the type of container and the size of being loaded and unloaded are restricted.
Summary of the invention
Task of the present utility model has solved general double-box hanger and can not be simultaneously two freight containers have been made to separate and draw in the problem of action, realized the packaged type double-box hanger flexible and latch hook device advance hook and unhook.
The technical solution of the utility model is as follows:
A kind of telescoping mechanism of double-box hanger and latch hook device, telescoping mechanism is a telescopic drive mechanism, it comprises HM Hydraulic Motor, reductor, sprocket wheel chain gearing, tightening device, the location coding apparatus, and the upper push-rod that is connected with chain, it also comprises middle part write-off box translation mechanism, and push-rod lock hook device up and down; Described middle part write-off box translation mechanism comprises translation hydraulic ram, lower push-rod, gusset piece, antifriction piece and end position limit switch, upper push-rod is placed in two sides of middle part write-off box, every side upper push-rod is connected with roller chain respectively, about two lower push-rods respectively by gusset piece with about two pairs of middle part write-off boxes be connected, about two lower push-rods be connected with a pair of translation hydraulic ram respectively again; The push-rod lock hook device comprises lower push-rod contraposition inhibiting device up and down, latch hook oil cylinder, and the latch hook that is connected with the latch hook oil cylinder.
During use, crane driver operation middle part telescoping mechanism is suspended on fully loaded 20 forty equivalent unit 40s of suspender on shipping and reselling on another market with two, moves freely in 0~1600mm (0~5 foot) spacing range, do to separate and draw action in, making up and down, the push-rod lock hook device breaks off relations and advances hook.Realized the flexible of packaged type double-box hanger reliably.
Description of drawings
Fig. 1 is the structural representation of a kind of double-box hanger telescoping mechanism and latch hook device.
Fig. 2 be among Fig. 1 latch hook device advance the hook scheme drawing.
Fig. 3 is the unhook scheme drawing of latch hook device among Fig. 1.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the conventional telescopic drive mechanism of packaged type double-box hanger comprises the retractable driving device 2 that is made of HM Hydraulic Motor, reductor etc., flexible push rod 1, the driving device that constitutes by drive sprocket 3, driven sprocket 8 and roller chain 4, tightening device, location coding apparatus, and the upper push-rod 9 that is connected with roller chain 4.
Middle part write-off box translation mechanism comprises translation hydraulic ram 7, lower push-rod 6, gusset piece 10, antifriction piece and end position limit switch.The end position limit switch has 40 feet zero-bit normal place limit switches and 45 feet end position limit switches.
Upper push-rod 9 is placed in two sides of middle part write-off box, and every side upper push-rod 9 is connected with roller chain 4 respectively.About two lower push-rods 6 respectively by gusset piece 10 with about in the middle part of two pairs write-off boxes be connected, about two lower push-rods 6 be connected with a pair of translation hydraulic ram 7 respectively again.
Push-rod lock hook device 5 comprises lower push-rod contraposition inhibiting device up and down, latch hook oil cylinder 51, and the latch hook 52 that is connected with latch hook oil cylinder 51.
When latch hook advances hook, lower push-rod is fused, be synchronized with the movement.When latch hook broke off relations, last lower push-rod separated, but self-movement separately.
When suspender when making normal fore and aft motion, the push rod latch hook breaks off relations up and down, promptly goes up lower push-rod and is in disengaged position.Fluid motor-driven retarder and sprocket wheel, roller chain, roller chain promotes telescopic girder and makes fore and aft motion.The fore and aft motion of this moment is equivalent to the fore and aft motion of common suspender.
When suspender during at the two case fore and aft motion of doing that band carries, its motion process is as follows: the driver goes to pair casing working states with suspender.Two case controllers on the suspender are positioned to telescopic girder 40 feet positions automatically, control two telescopic oil cylinders then the middle part movable stand is placed 40 feet normal places, lower push-rod contraposition inhibiting device sends signal on this moment, allow the latch hook cylinder action to carry out lock hook, allow middle part hoist cylinder action then, put down four middle part write-off box devices, so that carry out two casing workings.When the driver goes to single casing working state with suspender, then do the action of reverse order.
When suspender during at the two case fore and aft motion of doing that band carries, two case controller logics go to high pressure with normal pressure in the hydraulic efficiency pressure system automatically.Two translation hydraulic rams push away or draw the middle part movable stand to make two case motion of translations, and the HM Hydraulic Motor in the retractable driving device realizes idle running by dress bypass valve thereon simultaneously.When moving to 45 feet or 40 feet zero-bit positions, two case controller logics cut off the pressure circuit of hydraulic ram automatically, make it to stop to move.
