Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to an anti-deviation device for a rubber-tired gantry crane. Background Technology

[0002] A tire-mounted crane is a rotating boom crane that uses a tire-mounted chassis for mobility. It is a full-rotation crane with the lifting mechanism mounted on a specially designed chassis consisting of heavy-duty tires and axles. Its superstructure is basically the same as that of a crawler crane. To ensure the stability of the crane during installation operations, it is equipped with four retractable outriggers. On flat ground, it can perform small-capacity lifting and low-speed travel with the load without the outriggers. It consists of two parts: an upper carriage and a lower carriage. The upper carriage is the lifting operation section, equipped with the boom, hoisting mechanism, luffing mechanism, counterweight, and turntable; the lower carriage is the support and traveling section. The upper and lower carriages are connected by a slewing bearing. When lifting heavy loads, the outriggers are generally lowered to increase the support surface, and the crane body is leveled to ensure stability.

[0003] In the prior art, Chinese utility model application number CN202122168207.8 discloses a rubber tire gantry crane, including a support body, a support body including a vertical pole, a slide rail at the top of the vertical pole, a movable block at the bottom of the slide rail, a rotary motor on the front and rear sides of the movable block, a rotating wheel on the inner side of the movable block located on the slide rail, an iron chain at the bottom of the movable block, a hook at the bottom of the iron chain, a connecting cylinder at the bottom of the vertical pole, inclined support rods on both sides of the connecting cylinder, a support rod at the bottom of the connecting cylinder, a base plate at the bottom of the support rod, universal wheels on both sides of the bottom of the base plate, and a support structure on the front and rear sides of the base plate to support the device and prevent slippage. Through the set support structure, when vibration occurs due to the weight of the goods themselves, the device will not slip under the support of the support plate, making the lifting and lowering of goods more stable, avoiding accidents and improving safety.

[0004] Although the above technical solutions utilize a support plate to increase the contact area with the ground and improve the stability of cargo lifting and falling, gantry cranes mostly operate outdoors. During lifting, transportation, and loading, they are easily affected by external crosswinds, which can cause cargo to deflect during lifting. At the same time, during movement, the cargo may sway due to the inertia of movement. Therefore, we need to propose an anti-deviation device for rubber-tired gantry cranes. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-deviation device for a rubber-tired gantry crane, which limits the lifting of goods, prevents the goods from swaying and shaking in the horizontal direction, thereby increasing the stability of the lifted goods, ensuring that the goods do not shake excessively, and improving the safety of lifting and transporting goods, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation device for a rubber-tired gantry crane, comprising:

[0007] The lifting mechanism and the supporting beams installed at both ends of the lifting mechanism;

[0008] The support beam frame includes a column and a bottom beam welded to the bottom of the column. A limiting groove is opened on one side of the column, and an anti-deviation mechanism is provided in the limiting groove.

[0009] The anti-deviation mechanism includes a bidirectional screw and a side plate. Both ends of the bidirectional screw are threadedly connected to movable seats. Two sets of fixed seats are fixedly connected to one side of the side plate. Support columns are rotatably mounted on both sets of fixed seats. One end of each support column is rotatably mounted on a movable seat. The two sets of support columns are slidably mounted in the inner cavity of the limiting groove. The lower end of the bidirectional screw passes through the bottom beam and is driven by a second motor.

[0010] Preferably, a groove is provided on one side of the side plate, and an adjusting screw is rotatably disposed in the groove. One end of the adjusting screw is threadedly connected to a slider that is slidably disposed in the groove. A baffle is fixedly connected to one side of the slider, and the other end of the adjusting screw passes through the side plate and is driven by a first motor.

[0011] Preferably, the column is vertically arranged in the middle of the upper surface of the bottom beam, and both ends of the upper surface of the bottom beam are fixedly connected to the reinforcing beam. The upper ends of the two sets of reinforcing beams are fixedly connected to the two sides adjacent to the column and the limiting groove. The inner cavity of the bottom beam is provided with multiple sets of reinforcing plates.

[0012] Preferably, the support mechanism includes two sets of limiting rings, which are respectively fixedly connected to both ends of the inner cavity of the bottom beam. A rotating cylinder is rotatably arranged between the two sets of limiting rings. A lifting screw is threadedly connected to the inner cavity of the rotating cylinder. The lower end of the lifting screw passes through the bottom beam and is fixedly connected to an anti-slip base.

[0013] Preferably, the upper surface of the anti-slip base is fixedly connected with two sets of telescopic sleeve rods, and both ends of the lower surface of the bottom beam are equipped with rubber tire bodies, with the two sets of rubber tire bodies arranged between the two sets of lifting screws.

[0014] Preferably, the support mechanism further includes a third motor disposed at the top of the inner cavity of the bottom beam. The output shaft of the third motor is connected to a rotating shaft, and a gear is fixedly connected to the lower end of the rotating shaft. An external gear ring that meshes with the gear is disposed on the outer side of the rotating cylinder.

[0015] Preferably, the lifting mechanism includes a movable block and a connecting beam fixedly connected to the top of two sets of columns. Rotating wheels are rotatably arranged on both sides of the inner cavity of the movable block. Guide grooves for the rotating wheels to roll are opened on both sides of the connecting beam. A chain hook is arranged below the movable block. The shaft end of one set of rotating wheels passes through the movable block and is driven by a rotary motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model mainly utilizes the cooperation between the support beam, the anti-deviation mechanism, and the support mechanism. By adjusting the spacing of the movable seat through a bidirectional screw, the tilt angle of the support column changes, causing the side plate to move away from the column. This facilitates the baffle to clamp and hold the hoisted goods. At the same time, the height of the baffle can be adjusted according to the height of the hoisted goods to accommodate goods of different heights. This prevents goods from shifting during crane movement and due to external wind forces, improving the stability of goods hoisting and thus enhancing the safety of goods hoisting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an anti-deviation device for a rubber-tired gantry crane, comprising:

[0025] The lifting mechanism 100 and the supporting beams 200 installed at both ends of the lifting mechanism 100;

[0026] The support beam frame 200 includes a column 201 and a bottom beam 203 welded to the bottom of the column 201. A limiting groove 202 is opened on one side of the column 201, and an anti-deviation mechanism 300 is provided in the limiting groove 202. The bottom beam 203 is hollow, and a support mechanism 400 is provided at both ends of the inner cavity of the bottom beam 203.

[0027] The anti-deviation mechanism 300 includes a bidirectional screw 301 and a side plate 304. Both ends of the bidirectional screw 301 are threadedly connected to movable seats 302. Two sets of fixed seats 305 are fixedly connected to one side of the side plate 304. Support columns 303 are rotatably mounted on both sets of fixed seats 305. One end of the support column 303 is rotatably mounted on the movable seat 302. The two sets of support columns 303 are slidably mounted in the inner cavity of the limiting groove 202. The lower end of the bidirectional screw 301 passes through the bottom beam 203 and is driven by the second motor 3011.

[0028] A groove 306 is provided on one side of the side plate 304. An adjusting screw 307 is rotatably installed in the groove 306. One end of the adjusting screw 307 is threadedly connected to a slider 3010 that is slidably installed in the groove 306. A baffle 309 is fixedly connected to one side of the slider 3010. The other end of the adjusting screw 307 passes through the side plate 304 and is driven by a first motor 308. The first motor 308 drives the adjusting screw 307 to facilitate the adjustment of the position of the slider 3010 in the groove 306, thereby facilitating the positioning of the baffle 309 for higher or lower hoisted goods and improving the applicability.

[0029] The column 201 is vertically installed in the middle of the upper surface of the bottom beam 203. Both ends of the upper surface of the bottom beam 203 are fixedly connected to the reinforcing beams 600. The upper ends of the two sets of reinforcing beams 600 are fixedly connected to the two sides adjacent to the column 201 and the limiting groove 202. The inner cavity of the bottom beam 203 is provided with multiple sets of reinforcing plates 204. The strength of the bottom beam 203 is improved by using multiple sets of reinforcing plates 204, and the stability of the column 201 is improved by using the reinforcing beams 600, thereby improving the service life of the crane.

[0030] The support mechanism 400 includes two sets of limiting rings 401, which are fixedly connected to both ends of the inner cavity of the bottom beam 203. A rotating cylinder 402 is rotatably arranged between the two sets of limiting rings 401. A lifting screw 404 is threadedly connected to the inner cavity of the rotating cylinder 402. The lower end of the lifting screw 404 passes through the bottom beam 203 and is fixedly connected to an anti-slip base 405. The rotating cylinder 402 is threadedly connected to the lifting screw 404, which facilitates the rotation of the rotating cylinder 402 to drive the anti-slip base 405 to rise and fall stably, thereby improving the stability of the crane when lifting and lowering goods.

[0031] Two sets of telescopic sleeves 406 are fixedly connected to the upper surface of the anti-slip base 405. Rubber tire bodies 500 are installed at both ends of the lower surface of the bottom beam 203. The two sets of rubber tire bodies 500 are set between the two sets of lifting screws 404. The telescopic sleeves 406 improve the stability of the anti-slip base 405 and prevent the anti-slip base 405 from rotating synchronously with the rotating drum 402. At the same time, the rubber tire bodies 500 improve the efficiency of crane movement.

[0032] The support mechanism 400 also includes a third motor 407 located at the top of the inner cavity of the bottom beam 203. The output shaft of the third motor 407 is connected to a rotating shaft 408. A gear 409 is fixedly connected to the lower end of the rotating shaft 408. An external gear ring 403 that meshes with the gear 409 is provided on the outer side of the rotating drum 402. The third motor 407 drives the gear 409 on the rotating shaft 408 to mesh with the external gear ring 403, thereby facilitating the rotation of the rotating drum 402, improving the stability of the crane positioning, and thus improving the stability of cargo lifting and lowering.

[0033] The lifting mechanism 100 includes a movable block 103 and a connecting beam 101 fixedly connected to the top of two sets of columns 201. Rotating wheels 105 are rotatably arranged on both sides of the inner cavity of the movable block 103. Guide grooves 102 for the rotating wheels 105 to roll are opened on both sides of the connecting beam 101. A chain hook 106 is arranged below the movable block 103. The shaft end of one set of rotating wheels 105 passes through the movable block 103 and is driven by a rotary motor 104, which facilitates the lifting and transportation of goods. The specific working principle is existing technology and will not be described in detail.

[0034] In use, the crane moves to the cargo location via the rubber tire body 500. The third motor 407 drives the gear 409 on the rotating shaft 408 to mesh with the external gear ring 403, thereby causing the lifting screw 404 and the rotating drum 402 to rotate threadedly. Under the restriction of the telescopic sleeve 406 on the anti-slip base 405, the anti-slip base 405 is lowered stably to contact the ground, so that the lifting mechanism 100 can lift the cargo. After the cargo is lifted, the second motor 3011 of the anti-deviation mechanism 300 drives the bidirectional screw 301 to move the movable seat 30 The spacing of 2 is adjusted to reduce the angle between the two sets of support columns 303 and the horizontal plane, making it easier for the side plate 304 to approach the hoisted goods. The height of the hoisted goods allows the first motor 308 to drive the adjusting screw 307 to adjust the position of the slider 3010, thereby facilitating the height adjustment of the baffle 309. This ensures that the baffle 309 stably abuts against the goods, improving the stability of the goods during hoisting and avoiding the swaying and deviation of the goods caused by the inertia of the crane during movement and the influence of external wind force, thus improving the stability of the goods hoisting.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
