DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figures 1 to 4 A stable crane gantry is shown, comprising:

[0026] A gantry main body 1, a multi-stage telescopic rod 2 is fixedly provided at the bottom of both ends of the crossbeam of the gantry main body 1, and a movable rod 3 is fixedly provided at the bottom of the two multi-stage telescopic rods 2;

[0027] A movable block 4 is arranged at the front end of the movable rod 3. Two symmetrical clamping plates 5 are arranged at the front end of the movable block 4. A first slide groove 6 is opened at the front end of the movable block 4. Two first sliders 7 are arranged inside the first slide groove 6. The front ends of the two first sliders 7 are respectively fixedly connected with the two clamping plates 5. A bidirectional threaded rod 8 is arranged inside the first slide groove 6. One end of the bidirectional threaded rod 8 passes through the two first sliders 7 and extends to one side of the movable block 4. Both ends of the bidirectional threaded rod 8 are rotatably connected to both ends inside the first slide groove 6 through bearings. The bidirectional threaded rod 8 is threadedly connected to the two first sliders 7 and the thread directions are opposite. A rotating block 9 is fixedly provided at one end of the bidirectional threaded rod 8.

[0028] A second slide groove 10 is provided at the front end of the movable rod 3 , a second slider 11 is provided inside the second slide groove 10 , and a front end of the second slider 11 is fixedly connected to a rear end of the movable block 4 .

[0029] Move the movable block 4 to the rear side of the hook at the bottom end of the crossbeam of the portal frame body 1, so that the top end of the hook is located between the two clamping plates 5, and rotate the rotating block 9. The rotating block 9 drives the bidirectional threaded rod 8 to rotate. Since the bidirectional threaded rod 8 and the two first sliding blocks 7 are connected by threads, the two first sliding blocks 7 move toward each other as the bidirectional threaded rod 8 rotates. The two first sliding blocks 7 drive the two clamping plates 5 to approach each other, and the two clamping plates 5 will be clamped and fixed on the outside of the top end of the hook. In this way, the movable block 4 and the clamping plate 5 can be connected to the hook together.

[0030] The utility model limits and guides the hook and rope at the bottom end of the crossbeam of the gantry body 1 through two clamping plates 5 and a movable block 4, effectively avoiding the shaking of the goods when they move up, down, left and right, so that the goods can run more stably during the lifting process and have a better use effect. This embodiment specifically solves the problem in the prior art that when the crane gantry is actually used, the lifting rope inside the gantry is prone to shaking during the lifting process, which makes the goods run less stably during the lifting process, and the shaking of the goods is not conducive to its movement up, down, left and right, resulting in an insufficient use effect.

[0031] The utility model provides Figure 1 and Figure 5 A stable crane gantry is shown, and the bottom ends of the four legs of the gantry body 1 are fixed with fixing components, and the fixing components include a base plate 12 fixed to the bottom ends of the legs of the gantry body 1, a fixing plate 14 is provided at the bottom of the base plate 12, and anti-slip stripes are provided at the bottom end of the fixing plate 14, and two connecting rods 15 are fixed at the top of the fixing plate 14, and the top ends of the two connecting rods 15 pass through the base plate 12 and extend to the top of the base plate 12, and a connecting plate 16 is fixed at the top of the two connecting rods 15, and the top of the base plate 12 is rotatably connected to an adjusting screw 17 through a bearing, and the top end of the adjusting screw 17 passes through the middle of the connecting plate 16 and extends to the top of the connecting plate 16, and the adjusting screw 17 is connected to the connecting plate 16 by a thread, and a rotating disk 18 is fixed to the top of the adjusting screw 17.

[0032] A brake wheel 13 is fixedly provided at the bottom end of the bottom plate 12 , and the brake wheel 13 is arranged on the inner side of the fixing plate 14 .

[0033] After the gantry body 1 is moved to the position where it needs to be used, the rotating disk 18 is rotated, and the rotating disk 18 drives the adjusting screw 17 to rotate. Since the adjusting screw 17 is connected to the connecting plate 16 by a thread, the connecting plate 16 moves downward with the rotation of the adjusting screw 17, and the connecting plate 16 drives the two connecting rods 15 to move downward. The two connecting rods 15 drive the fixed plate 14 to move downward, and the fixed plate 14 will contact the ground, so that the gantry body 1 can be fixed. The legs of the gantry body 1 are fixed by fixing components, so that the support of the gantry body 1 is more stable, which avoids the movement of the gantry body 1 during lifting, and the fixing effect is better.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
