Abstract
The utility model provides a lifting hook and grab bucket dual-purpose winch control device of a crane and relates to the technical field of hoisting machinery for loading and unloading of materials. Two speed-reduction motors are respectively arranged on a machine frame, and one end of a main shaft of each group of lifting winch is correspondingly connected with an output end of each speed-reduction motor. The lifting hook and grab bucket dual-purpose winch control device of the crane is characterized in that the main shafts of the two groups of lifting winch are arranged in a coaxial mode, and the other end of the main shaft of each group of lifting winch is connected with a detachable coupling. When the cane is used to control a grab bucket and enables the couplings to be separated, the two lifting winches are respectively controlled by the two groups of speed-reduction motors. When the crane is used to control the lifting hook and enables the couplings to be closed, the two lifting winches control a lifting rope in a synclastic and synchronous mode. Therefore, weight falling accidents due to the fact that the steel wire rope is completely unwound and breaks away from a winding drum are avoided.
Description
Technical field
The utility model relates to material handling elevator machinery technical field, particularly the elevator technical field of the material lifting of control lifting.
Background technology
Crane hoisting has two cover elevators, and the bulk goods operation that can be used for grabbing bucket also can be used for the loading and unloading of hook member goods.Former hoisting crane two overlaps between the elevators without hitch bar, when using suspension hook, because the two inconsistent and motor speeds of manually doing also can not be identical about operating personal, the difference of rotating speed causes restricting on the reel many and restricts on the another reel and lack, and steel rope will occur and shake off reel and cause the weight falling accident when the steel rope on the reel discharges.
Summary of the invention
The utility model purpose is suspension hook and the dual-purpose winch control device of grab bucket for a kind of safe hoisting crane of suspension hook and grab bucket dual purpose rubber tyre gantry crane design.
The utility model comprises two reducing motors, two groups of winchs that hoist, described two reducing motors are arranged on the frame, one end of the every group of winch main shaft that hoists and the corresponding connection of the mouth of a reducing motor, the main shaft coaxial arrangement that it is characterized in that two groups of winchs that hoist connects detachable coupler between the other end of the every group of winch main shaft that hoists.
When hoisting crane is used for grab bucket enforcement control, make coupler separately, two winchs that hoist are respectively by two groups of reducing motor controls; When hoisting crane was used for suspension hook enforcement control, coupler is closed, and two winchs that hoist were controlled two winch synchro control lifting ropes that hoist in the same way, can avoid steel rope to shake off reel because giving out light and cause the weight falling accident.
Produce and the enforcement use for convenient, detachable coupler described in the utility model is comprised of left catcher, right catcher, contiguous block and tie bolt, described left catcher is connected on the main shaft of one group of winch that hoists, right catcher is connected to another group and hoists on the main shaft of winch, the two ends of contiguous block respectively by tie bolt and left catcher be connected catcher and be connected.Contiguous block can be installed and removed easily, to adapt to the use of different operating modes, adopts this device simple and practical, safe and reliable.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the left side of detachable coupler among Fig. 1 is to view.
The specific embodiment
As shown in Figure 1, the utility model is provided with the reducing motor 1,2 that is arranged on the frame, winch 3,4 hoists, the end of main shaft of winch 3 of hoisting is connected with the mouth of reducing motor 1, the end of main shaft of winch 4 of hoisting is connected with the mouth of reducing motor 2, two groups of winchs 3 that hoist, 4 main shaft coaxial arrangement connect detachable coupler 5 between the other end of the winch 3 that hoists, 4 main shaft.
As shown in Figure 1, 2, detachable coupler 5 is comprised of a left catcher 5-1, right catcher 5-2, a contiguous block 5-3 and two tie bolt 5-4,5-5, left catcher 5-1 links to each other by the main shaft of attaching parts 6 with the winch 3 that hoists towards an end of the winch 3 that hoists, and right catcher 5-2 links to each other by the main shaft of attaching parts 7 with the winch 4 that hoists towards an end of the winch 4 that hoists.
Offer respectively bolt hole on left catcher 5-1 and the right catcher 5-2, offer respectively contiguous block 5-3 on the left catcher 5-1 face relative with right catcher 5-2 and stretch into the hole, bolt hole is offered respectively at the two ends of contiguous block 5-3.
The two ends of contiguous block 5-3 are inserted into respectively stretching in the hole of left catcher 5-1 and right catcher 5-2, and tie bolt 5-4 is placed through in the bolt hole of left catcher 5-1 and contiguous block 5-3 one end, and adopt nut to fix; Tie bolt 5-5 is placed through in the bolt hole of right catcher 5-2 and the contiguous block 5-3 other end, and adopts nut to fix.
When the utility model is used for implementing grab bucket control, remove the connecting panel 5-3 between left catcher 5-1 and the right catcher 5-2.
When the utility model is used for implementing suspension hook control, in the connecting panel 5-3 connection between left catcher 5-1 and the right catcher 5-2.
