Technical field
The utility model relates to the peripheral equipment of high pedestal jib crane, more specifically refers to the automatic anchoring device of a kind of hoisting crane.
Background technology
The rotation anchoring device is as a kind of windproof safety device, be mainly used in high pedestal jib crane, its effect is under off working state, lasting strong wind of opposing or sharp-edged gust are to the effect of hoisting crane rotatable portion, avoid the hoisting crane rotatable portion under the effect of wind-force, with nearby device or building collision, accidents caused.Therefore the rotatable portion of hoisting crane must be fixed, the rotation anchoring device is the requisite safety device of seat type lifting.
The anchoring device principle is to adopt the anchor pin pin to go into anchor block, and rotatable part (or guide holder) is fixed in non-rotatable parts (or anchor block), and general, anchor pin is installed on the rotatable part, and anchor block is installed on the non-rotatable parts.In present actual mechanical process, because anchor pin needs the operator to adopt manual mode that the artificial pin of anchor pin is gone into anchor block, because, crane driver can't directly be seen the position of anchor block, must there be the auxilian to cooperate conductor driver to carry out contraposition in addition, just can finishes the process that anchor block is inserted in anchor pin.Whole process is comparatively complicated, inefficiency, but also have the danger that injures operating personal, do not meet the desired standard of safety in production.
Summary of the invention
The purpose of this utility model is the problem that exists at traditional anchoring device, proposes a kind of automatic anchoring device of hoisting crane that the auxilian cooperates that need not.
To achieve these goals, the utility model adopts following technical scheme, and the automatic anchoring device of this hoisting crane comprises anchor block, guide holder, anchor pin, anchor pin is placed through guide holder, and guide holder is positioned at the top of anchor block, in addition, this anchoring device also comprises electric pushrod, control unit
Described electric pushrod further comprises motor, retarder, flexible screw rod, the output shaft of motor drives retarder, the output gear of retarder is by driving flexible screw rod up-and-down movement with its ingear nut, the bottom of flexible screw rod is connected with anchor pin, the flexible screw rod up-and-down movement of described control unit control electric pushrod.
Described control unit further comprises screw rod rising branch road and screw rod decline branch road, and screw rod rising branch road and screw rod decline branch road comprise master cock, contactless switch, limit switch respectively, and master cock, contactless switch, limit switch are connected in series mutually.
The limit switch of described screw rod rising branch road and screw rod decline branch road is arranged at the both sides of flexible screw rod respectively, and goes to upper and lower and shift to install.
The utility model has adopted technique scheme, on the basis of traditional hoisting crane anchoring device, electric pushrod, control unit have been increased, electric pushrod further comprises motor, retarder, flexible screw rod, the output shaft of motor drives retarder, the output gear of retarder is by driving flexible screw rod up-and-down movement with its ingear nut, the bottom of flexible screw rod is connected with anchor pin, and the flexible screw rod up-and-down movement of control unit control electric pushrod.When needs fixedly the time, only need guide holder and anchor block just can be fixed on the anchor block by control unit, do not need the operator to adopt manual mode that anchor block is manually inserted in anchor pin.Simplified the fixation procedure of guide holder and anchor block, improved production efficiency and reduced the danger of operating personal.
Description of drawings
Fig. 1 is the lock-out state scheme drawing for the utility model anchoring device.
Fig. 2 is the free state scheme drawing for the utility model anchoring device.
Fig. 3 is the utility model anchoring device electrical principle scheme drawing.
The specific embodiment
For further specifying above-mentioned purpose of the present utility model, technical scheme and effect, in conjunction with above-mentioned each figure the utility model is described in detail by the following examples.
See also Fig. 1, shown in Figure 2, the automatic anchoring device of the utility model hoisting crane comprises anchor block 1, guide holder 2, anchor pin 3, anchor pin 3 is placed through guide holder 2, guide holder 2 is positioned at the top of anchor block 1, these and traditional anchoring device be indistinction still, different is that this anchoring device also comprises electric pushrod 4, control unit 5.
Described electric pushrod 4 further comprises motor 41, retarder 42, flexible screw rod 43, the output shaft of motor 41 drives retarder 42, the output gear of retarder 42 moves up and down by driving flexible screw rod 43 with its ingear nut 44, and the bottom of flexible screw rod 43 is connected with anchor pin 3.Flexible screw rod 43 up-and-down movements of described control unit 5 control electric pushrods 4.
Please cooperate shown in Figure 3 again, control unit 5 further comprises screw rod rising branch road and screw rod decline branch road, screw rod rising branch road and screw rod decline branch road comprise master cock 51 (1QA, 2QA), contactless switch 52 (CJ), limit switch 53 (1XWK, 2XWK) respectively, and master cock 51 (1QA, 2QA), contactless switch 52 (CJ), limit switch 53 (1XWK, 2XWK) are connected in series mutually.In this Fig. 3,1QA is gentry's compression screw arbor 43 rising switches, and 2QA is last gentry compression screw arbor 43 decline switches, and 1XWK is the rising limit switch, and 2XWK is the decline limit switch, and RJ is a thermal relay, and HK is an air break switch, and 1RD-5RD is a fuse, and D is a motor.
The limit switch 53 of described screw rod rising branch road and screw rod decline branch road is arranged at the both sides of flexible screw rod 43 respectively, and goes to upper and lower and shift to install.
When needs are gone into anchor block with the anchor pin pin, when the operator presses switch 2QA, contactless switch 2C obtains, screw rod rising branch road is chain, and motor D starts, and drives anchor pin 3 and descends, when anchor pin 3 drops to the lower limit position, lower position switch 2XWK disconnects, and motor D stops operating, and anchoring device is in the lock state.When needs with anchoring device when lock-out state becomes free state, when the operator presses out 1QA, contactless switch 1C obtains, screw rod decline branch road is chain, and motor D starts, and drives anchor pin 3 and rises, when anchor pin 3 rises to the upper limit position, upper limit position switch 1XWK disconnects, and motor D stops operating, and anchoring device then is in free state.
Above-mentioned lock-out state is guide holder (turning unit) and locks mutually with anchor block (non-rotatable parts) by anchor pin, and free state is the state that guide holder (turning unit) and anchor block (non-rotatable parts) are separated from each other.
In order the handled easily person successfully anchor pin 3 to be inserted in the anchor block 1 like clockwork, can on guide holder 2, set up a pick up camera 6, pick up camera 6 connects a monitor screen 7 by lead.In the installation at the scene, pick up camera 6, master cock 51 all place the driver's cab (empty frame table shows) that uses for the operator, contactless switch 52 places electrical control cubicles (another empty frame), therefore, the utility model anchoring device can be operated by a driver easily, in driver's cab, by monitor screen with press switch, just can finish the pin of anchoring device and go into and the work of opening out, improve labor efficiency and safety greatly.
Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
