Description

Technical Field

[0001] The invention belongs to the technical field of cranes, in particular to a horizontal anchoring device for cranes. Background Art

[0002] Wind protection for cranes includes dynamic and static wind protection, which is differentiated according to whether the crane is working or not. When the crane is not working, it is static wind protection, and when it is working, it is dynamic wind protection. During the operation of the crane, the machinery and operators are working and are affected by the force of the wind. Therefore, once wind damage occurs, it will bring unpredictable results.

[0003] Static windproof devices often use a combination of a trolley anchoring device and a windproof system. The traditional vertical trolley anchoring uses manual or electric methods to vertically insert the anchoring plate into the anchoring pit. The vertical anchoring can only withstand the overturning force along the track direction, and has no effect on the overturning force in the direction perpendicular to the track; the windproof zipper can withstand both horizontal force and vertical force, and can also withstand upward pull force. Generally, the two are used in combination to achieve the effect of static windproof. This combination method is relatively mature, but there are also many disadvantages: 1. The vertical anchoring cannot withstand the overturning force in the vertical track direction, and lacks stability for the steel structure of the whole machine. 2. The use of the windproof system compensates for its inability to withstand the overturning force in the vertical track direction. Similarly, the manufacturing cost and labor cost are correspondingly increased, which is not conducive to meeting the high efficiency and safety requirements of static windproofing. Summary of the invention

[0004] In order to solve the problem of high manufacturing and use costs during dynamic wind protection operations, the present invention provides a crane horizontal anchoring device.

[0005] The present invention is achieved through the following technical solutions: A horizontal anchoring device for a crane comprises a support body, wherein the support body comprises a support upper box and a support lower box which are arranged in sequence from top to bottom, and the support upper box and the support lower box are L-shaped in structure as a whole; a penetrating anchoring hole is provided at the lower portion of the support upper box, an anchoring plate is slidably arranged in the anchoring hole, a push rod is connected to one side of the anchoring plate, and the push rod is horizontally mounted on the support lower box; an anchoring seat is provided on the ground at a windproof point on the side of the anchoring hole away from the push rod, and the anchoring seat can fix one end of the anchoring plate extending out of the anchoring hole.

[0006] The anchor plate is pushed outward by a horizontal push rod arranged on one side of the box body on the bracket. After reaching the windproof point, it cooperates with the anchor seat to provide a reverse horizontal force and anti-overturning moment along the track, thereby effectively preventing the equipment from slipping along the track direction and overturning in the direction perpendicular to the track. The structure is simple and the operation is quick, which reduces the complexity of use, labor cost and production cost.

[0007] A further improvement of the present invention is that one end of the sleeve of the push rod is hinged with a push rod base, the push rod base is installed on the lower box of the bracket, and the free telescopic end of the push rod is hinged with the anchor plate, which helps to improve the convenience of assembling the push rod on the lower box of the bracket and realize quick operation.

[0008] A further improvement of the present invention is that a drive motor with a vertical axis is installed on the sleeve end of the push rod, and the drive motor drives the push rod to extend through the transmission assembly. The drive motor drives the push rod to extend and retract.

[0009] A further improvement of the present invention is that a handle capable of driving the output shaft of the drive motor to rotate is provided on the top of the drive motor, and the action of the push rod can be fine-tuned by operating the handle.

[0010] A further improvement of the present invention is that the anchor seat is fixed to the ground at the windproof point by anchor bolts, which helps to improve the fixing strength of the anchor plate.

[0011] A further improvement of the present invention is that a dust cover is provided on the bracket lower box on one side of the bracket upper box, and the dust cover is provided above the push rod, which helps to form dust protection for the equipment parts that push the anchor plate when idle.

[0012] A further improvement of the present invention is that an anti-wear sleeve adapted to the anchor plate is embedded in the anchor hole to reduce wear on the anchor plate and improve the guiding property of the anchor plate.

[0013] A further improvement of the present invention is that the anti-wear sleeve is made of copper alloy.

[0014] It can be seen from the above technical scheme that the beneficial effects of the present invention are: by means of a horizontal push rod arranged on one side of the box body on the bracket, the anchor plate is pushed outward, and after reaching the windproof point, it cooperates with the anchor seat to provide a reverse horizontal force and anti-overturning moment along the track, thereby effectively preventing the equipment from slipping along the track direction and overturning in the direction perpendicular to the track. The structure is simple and the operation is quick, which reduces the complexity of use, labor costs and production costs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] like Figure 1-3As shown, a horizontal anchoring device for a crane comprises a support body, the top of which is connected to an upper box member 7 via a flange, and the upper box member 7 is welded to the end beam of the crane. The support body comprises a support upper box 1 and a support lower box 2 arranged in sequence from top to bottom, and the support upper box 1 and the support lower box 2 are L-shaped structures as a whole; a push rod 3 arranged horizontally and pointing to the support upper box 1 is arranged on the top surface of the support lower box 2 on one side of the support upper box 1; an anchor hole 11 is opened at the lower part of the support upper box 1, an anchor plate 5 is slidably arranged in the anchor hole 11, and the push rod 3 is connected to one side of the anchor plate. An anchor seat 6 is arranged on the ground at the windproof point on the side of the anchor hole 11 away from the push rod 3, and the anchor seat 6 can fix one end of the anchor plate extending from the anchor hole 11; the anchor seat 6 is fixed to the ground at the windproof point by anchor bolts. By means of the push rod 3 arranged on one side of the box body 1 on the bracket, the telescopic movement of the anchor plate 5 after passing through the anchor hole 11 is completed. After reaching the windproof point, it cooperates with the anchor seat 6 to provide a reverse horizontal force and anti-overturning moment along the track, thereby effectively preventing the equipment from slipping along the track direction and overturning in the direction perpendicular to the track.

[0022] The anchor hole 11 is embedded with an anti-wear sleeve 12 adapted to the anchor plate 5; the anti-wear sleeve 12 is made of copper alloy to reduce the wear between the anchor plate 5 and the upper box 1 of the bracket, and improve the guiding performance of the anchor plate 5.

[0023] A push rod base 31 is hinged at one end of the sleeve of the push rod 3, and the push rod base 31 is installed on the lower box body 2 of the bracket. The free telescopic end of the push rod 3 is hinged to the anchor plate 5 through a hinge seat 32. It helps to improve the convenience of assembling the push rod 3 on the lower box body 2 of the bracket and realize quick operation. A drive motor 4 with a vertical axis is installed on the sleeve end of the push rod 3, and the drive motor 4 drives the push rod 3 to extend through a transmission assembly.
