Description

Technical Field

Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam. It can walk directly on the ground track, and both ends of the main beam can have outward cantilever beams.

[0003] In order to ensure the stability of the gantry crane, it is necessary to position the gantry crane with the help of an anchoring device. For example, the related technology (patent document with publication number CN203345944U) discloses an anchoring device for the gantry crane. The anchoring device of the gantry crane is inserted into the fixing hole through the plug plate, so that the entire gantry crane can be fixed. In windy or other rainy weather, it has the advantage of ensuring the personal safety of the staff.

[0004] In the prior art, the gantry crane is often connected to the ground by fixing with anchor bolts. The specific method is as follows: one end of the wire rope is connected to the outer wall of the horizontal frame at the top of the gantry crane, and the other end is fixed to the anchor device. The anchor device connects and fixes the base to the ground through the anchor bolts, so as to stably connect the gantry crane to the ground. However, when the wire rope is fixed to the anchor device, due to the high hardness of the wire rope itself, when the end of the wire rope is folded in half and passed through the inner cavity of the anchor device, the gap at the folded part of the wire rope is large, causing the wire rope to still slide relative to the anchor device under the action of external force, and it is impossible to achieve a stable connection between the wire rope and the anchor device, which leads to an unstable connection between the gantry crane and the anchor device.

Limiting components for limiting the movable plate 8 to move in the vertical direction are arranged on both sides of the movable plate 8, and the limiting components are used to ensure that the moving direction of the movable plate 8 always remains vertical; the limiting component includes a limiting groove 10 provided on the inner side wall of the second fixed seat 5 in the vertical direction, and also includes a limiting block 11 slidably embedded in the inner cavity of the limiting groove 10, and the limiting block 11 is fixedly connected to the movable plate 8. In the process of the movable plate 8 moving downward, the limiting block 11 installed on the outer wall of the movable plate 8 moves along the inner cavity of the limiting groove 10 to limit the movement of the movable plate 8 and the positioning claw 7 in the vertical direction;

[0027] When the gantry crane is connected and positioned with the anchor device, one end of the wire rope 4 is fixed to the outer wall of the horizontal frame at the top of the gantry crane, and the other end of the wire rope 4 passes through the inner cavity of the positioning ring 3 and is folded, and the overlapping parts of the folded wire rope 4 are respectively passed through the space between the positioning claws 7 and the positioning plates 6 of the two groups of positioning units, and the screws 9 in the two groups of positioning units are respectively driven to rotate, so that the moving plate 8 connected to the bottom end of the screw 9 drives the positioning claw 7 to gradually move downward, and the spacing between the positioning claw 7 and the positioning plate 6 gradually becomes smaller, until the positioning claw 7 moving downward clamps the folded part of the wire rope 4 in the U-shaped positioning space formed between the positioning plate 6 and the positioning claw 7, thereby connecting the wire rope 4 and the positioning ring 3 for two-point positioning, that is, realizing a stable connection between the gantry crane and the anchor device; at the same time, in the process of the moving plate 8 moving downward, the limit block 11 installed on the outer wall of the moving plate 8 moves along the inner cavity of the limit groove 10 to limit the movement of the moving plate 8 and the positioning claw 7 in the vertical direction.

[0028] See also Figure 2 and Figure 3As shown, a supporting seat 12 is provided at the bottom end of the two groups of positioning units, and two groups of lifting components are provided in the inner cavity of the supporting seat 12. The two groups of lifting components are connected to the two positioning units respectively, and the positioning units are prompted to adjust their positions in the vertical direction through the lifting components to adjust the heights of the left and right groups of positioning units; each group of lifting components includes a cylinder 13 installed at the bottom end of the inner wall of the supporting seat 12, and the cylinder 13 is a self-locking cylinder commonly used in the existing market, and its output end can stay at any position and be locked, which is not repeated here. The output end of the cylinder 13 is connected to the bottom end of the second fixed seat 5 at the corresponding position, and the second fixed The seat 5 is fixedly installed with a moving block 14, and the inner wall of the supporting seat 12 is fixedly installed with a limiting rod 15 in the vertical direction, and the moving block 14 is slidably sleeved on the outer side of the limiting rod 15. The second fixed seat 5 connected at the corresponding position is prompted to move in the vertical direction by the opened cylinder 13, so that the positions of the positioning plate 6 and the positioning claw 7 in the inner cavity of the second fixed seat 5 can adapt to the inclination angle of the wire rope 4. During the movement of the second fixed seat 5, the moving block 14 installed on the outer wall can be prompted to move along the outer wall of the limiting rod 15 at the corresponding position, so as to assist the cylinder 13 in driving the second fixed seat 5 to move in the vertical direction.

[0029] See also Figure 1 and Figure 4 As shown, a displacement unit is provided at the bottom end of the supporting seat 12, and the displacement unit includes a slide groove 16 opened on the upper surface of the base 1 in a horizontal direction. The inner cavity of the slide groove 16 is rotatably connected to a lead screw 17 through a bearing. A slider 18 is threadedly sleeved on the outer wall of the lead screw 17, and the slider 18 is slidably embedded in the inner cavity of the slide groove 16. A connecting seat 19 is fixedly installed on the top of the slider 18, and the connecting seat 19 is connected to the bottom end of the outer wall of the supporting seat 12. By rotating the lead screw 17, the slider 18 threadedly sleeved on the outer wall is caused to move to the right along the outer wall of the lead screw 17 until the slider 18 on the right side moves to a suitable position, causing the positioning plate 6 and the positioning claw 7 set on the top of the right slider 18 to move to the positioning position, ensuring that the positioned wire rope 4 can be folded and clamped on the outer wall of the positioning ring 3.

[0030] In order to conveniently drive the screw 17 to rotate, the left side of the screw 17 extends out of the side wall of the base 1 and is equipped with a hand wheel 20. By rotating the hand wheel 20 to drive the screw 17 to rotate, the position of the positioning unit can be more conveniently adjusted, and the operation is more convenient.

[0031] The working principle of the anchoring device of a gantry crane in this embodiment is as follows:

[0032] The heights of the two positioning units are adjusted in advance according to the height of the gantry crane: the second fixing seat 5 connected at the corresponding position is moved in the vertical direction by the opened cylinder 13, so that the positions of the positioning plate 6 and the positioning claw 7 in the inner cavity of the second fixing seat 5 can adapt to the inclination angle of the wire rope 4, and ensure that when the wire rope 4 connected between the gantry crane and the anchoring device is tilted, the positioning plates 6 and the positioning claws 7 of the two sets of positioning units can be set high and low to meet the requirements of the wire rope 4 being tilted through and positioned;

[0033] The spacing between the positioning unit and the positioning ring 3 is adjusted according to the hardness of the steel wire rope 4: the driving hand wheel 20 drives the lead screw 17 to rotate, and the lead screw 17 causes the slider 18 with the outer wall thread sleeve to move to the right along the outer wall of the lead screw 17, until the slider 18 on the right side moves to a suitable position, causing the positioning plate 6 and the positioning claw 7 set on the top of the slider 18 on the right side to move to the positioning position, ensuring that the steel wire rope 4 after positioning can be folded and clamped on the outer wall of the positioning ring 3, avoiding the positioning unit from being too far away from the folding position of the steel wire rope 4, resulting in a situation where the folding position of the steel wire rope 4 still leaves a large space relative to the positioning ring 3;

[0034] When the gantry crane is connected and positioned with the anchor device, one end of the wire rope 4 is fixed to the outer wall of the horizontal frame at the top of the gantry crane, and the other end of the wire rope 4 passes through the inner cavity of the positioning ring 3 and is folded, and the overlapping parts of the folded wire rope 4 are respectively passed through the space between the positioning claws 7 and the positioning plates 6 of the two groups of positioning units, and the screws 9 in the two groups of positioning units are respectively driven to rotate, so that the moving plate 8 connected to the bottom end of the screw 9 drives the positioning claw 7 to gradually move downward, and the spacing between the positioning claw 7 and the positioning plate 6 gradually becomes smaller, until the positioning claw 7 moving downward clamps the folded part of the wire rope 4 in the U-shaped positioning space formed between the positioning plate 6 and the positioning claw 7, thereby connecting the wire rope 4 and the positioning ring 3 for two-point positioning, that is, realizing a stable connection between the gantry crane and the anchor device; at the same time, in the process of the moving plate 8 moving downward, the limit block 11 installed on the outer wall of the moving plate 8 moves along the inner cavity of the limit groove 10 to limit the movement of the moving plate 8 and the positioning claw 7 in the vertical direction;

[0035] The utility model can enable the folded wire rope 4 to be folded and clamped at the positioning ring 3, thereby avoiding the phenomenon that the wire rope 4 slides relative to the positioning ring 3 due to the larger gap at the folded part, and the connection and positioning between the wire rope 4 and the positioning ring 3 is more stable, thereby ensuring the stability of the anchor connection between the gantry crane and the ground, and the heights of the two groups of positioning units can be flexibly adjusted to ensure that the wire rope 4 inclined between the gantry crane and the ground can achieve two-point positioning with different inclinations according to the positioning requirements of different places. In addition, according to the different hardness of the wire rope 4, the position of the positioning unit can be adjusted, and the equipment is flexible to use and has strong versatility.

[0036] It is also worth mentioning that the present application is intended to achieve a tight connection between the wire rope 4 and the positioning ring 3. In order to ensure that the positioning ring 3 can be relatively tilted within a normal range relative to the first fixed seat 2, sufficient gap space needs to be left between the positioning ring 3 and the first fixed seat 2. This setting is the prior art and will not be elaborated in this application.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
