Description

Technical Field

[0001] The present invention relates to the technical field of beam erecting cranes, and more specifically, to a three-dimensional gantry beam erecting crane with a ball-jointed module trolley for rapid assembly. Background Art

[0002] Gantry crane, also known as gantry crane, is a variation of bridge crane. Gantry crane is a bridge-type crane whose bridge is supported on the ground track by legs on both sides. Structurally, it is composed of a gantry, trolley running mechanism, lifting trolley and electrical parts. In order to expand the operating range of the crane, the main beam can extend beyond the legs to one or both sides to form a cantilever. A lifting trolley with an arm can also be used to expand the operating range of the crane by pitching and rotating the arm. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. It is mainly used for loading and unloading operations of outdoor freight yards, material yards, bulk cargo and bridge erection.

[0003] At present, in response to the needs of bridge erection: on the one hand, since there are straight bridges and curved bridges, gantry cranes cannot walk on curved tracks, and it is difficult to meet the requirements of erecting curved steel beams and walking horizontally; on the other hand, the gantry crane single hook lifts steel beams, and it is difficult to achieve multi-degree-of-freedom changes in segmental steel beams at high altitudes, and it is impossible to adjust the various directions of the steel beams in three-dimensional space. At the same time, it is also impossible to complete the rapid alignment of steel beams, and it is difficult to meet the requirements of accurate alignment of steel beams at high altitudes; on the other hand, the gantry crane single hook lifts heavy objects, and its lifting steel ropes need to form a triangle to lift the heavy objects. The steel ropes above the steel beam surface are relatively long, and the total height of the gantry crane needs to be much higher; on the fourth hand, a single gantry crane is not a model The modular design cannot meet the requirements of assembling beam-erecting equipment of different sizes and lifting tonnages according to engineering needs, cannot realize the requirements of one machine for multiple uses, and cannot make flexible adjustments according to the actual environment. Its maneuverability needs to be improved. At the same time, operators need to lubricate the ball joints on the ball-jointed modular trolleys regularly to meet the smoothness of the ball joints. However, due to the local narrow positions on the surfaces of the ball joints on the ball-jointed modular trolleys and the complex coordination relationship between the ball joints and the modular trolleys, the needs of comprehensive lubrication cannot be effectively met during the lubrication and adjustment process. At the same time, the operation is difficult, which delays the construction period to a certain extent. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a three-dimensional gantry crane with a ball-jointed modular trolley for rapid assembly. By setting a Bailey track beam, a ball-jointed support, a ball-jointed modular trolley, a modular main beam, an assembled gantry, a modular walking lifting trolley, and a hydraulic and electrical control system, and utilizing the mutual cooperation of the four groups of ball-jointed modular trolleys, each of which can rotate around its own center and travel on a straight or curved track under the guidance of the rail. The assembled gantry is composed of a standard modular steel pipe main column and a Bailey beam, and can be assembled into gantries of different sizes as needed. The four modular walking lifting trolleys can be wheel-rail modular walking lifting trolleys or hydraulic sliding modular walking lifting trolleys.

It can better realize the accurate and rapid positioning of heavy objects in three-dimensional space with multiple degrees of freedom at high altitude, which can improve construction efficiency and safety and reliability. At the same time, due to the vertical state of the steel rope of the multi-hanging point hoisting, the steel rope is triangularly hoisted relative to the single hook. Under the working conditions of the same lifting height, the gantry height can be reduced. The single-main ball-hook module trolley has unique technical performance. Since the single-main ball-hook module trolley can rotate around its own center, under the guidance of the rails, it can travel on an arc track like a train. Since the ball joint inside the ball-hook module trolley has an automatic self-aligning function, it can ensure that the force above passes through the center of the ball-hook module trolley and can adapt to running on a track surface with poor conditions.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention sets Bailey track beams, ball-jointed supports, ball-jointed module trolleys, modular main beams, assembled portal frames, modular traveling hoisting trolleys, hydraulic and electrical control systems, and utilizes the mutual cooperation of the four sets of ball-jointed module trolleys to rotate around their own centers. Under the guidance of the rails, the four sets of ball-jointed module trolleys can travel on straight or curved tracks. The assembled portal frame is composed of standard modular steel pipe main columns and Bailey beams, and can be assembled into portal frames of different sizes as needed, with high flexibility and adaptability.

[0016] Four modular traveling hoisting trolleys can be wheel-rail modular traveling hoisting trolleys or hydraulic sliding modular traveling hoisting trolleys. The four lifting points formed by the four modular traveling hoisting trolleys can realize four-change three-force through wire winding, and lift the heavy objects together. Each hook can realize lifting action in three-dimensional space, and can realize centralized control. 1 to 4 lifting points can be controlled in any combination. Each lifting point can be controlled individually to realize up and down, left and right movements, and the whole machine can realize forward and backward movement. It can better realize the effect of multi-degree-of-freedom accurate, fast and automatic alignment in high-altitude three-dimensional space when lifting heavy objects, which can improve construction efficiency and safety and reliability. At the same time, because the steel rope of multi-hanging point hoisting is in a vertical state, compared with the single hook whose steel rope is triangular hoisting, the height of the gantry can be reduced under the working conditions of the same lifting height;

[0017] The single-main ball-jointed modular trolley has unique technical performance. Since the single-main ball-jointed modular trolley can rotate around its own center, under the guidance of the rail, it can travel on a curved track like a train. Since the ball joint inside the spherical joint modular trolley has an automatic self-aligning function, it can ensure that the force on it passes through the center of the spherical joint modular trolley and can adapt to running on a track surface with poor conditions. Each spherical joint modular trolley can rotate 90° to achieve 90° vertical and horizontal travel;

[0018] By making full use of the modular Bailey beam, modular walking hoisting trolley, steel pipe main column and other main structures to form a modular design, it can be quickly assembled into ball-jointed modular trolleys of different sizes and lifting capacities, and can quickly assemble three-dimensional gantry cranes to meet different construction conditions. When the project is completed, the rented modular structural parts can be returned to the lessee to achieve the effect of ready-to-use and return, maximize the use of effective social resources, and do not need to store structural parts in a fixed position, but only need to store core key mechanism assembly parts and electrical hydraulic systems and other major equipment, thereby realizing the modularization of construction equipment assembly, socialization of resources, and rapid turnover of social resources, which can greatly reduce construction costs and equipment purchase costs;

[0019] As the arc surface moves downward with the ball joint, it contacts and squeezes the upper surface of the absorption sponge, thereby gradually applying pressure to the entire outer side surface, thereby gradually squeezing out the lubricating oil contained in it, and then the precipitated grease will pass through the filter holes inside the arc filter plate in turn, and drip into the inside of the arc groove, and finally flow out from the opening at the bottom end of one side under the drainage action of the arc groove, and be guided to the surface of the ball joint, and gradually cover the surface of the ball joint with the rotation of the ball joint and the rotating groove, thereby achieving adaptive lubrication operation, and eliminating the need for operators to repeatedly provide lubrication operations, while reducing the difficulty of operators to lubricate the local narrow position of the ball joint, greatly improving the degree of automation of the device, and in the process of rotating and adjusting the ball joint support, the lubrication process can be passively completed, further improving the practicality of the overall equipment.

[0047] The upper part of the connecting support 33 is connected to the ground beam below the assembled door frame 1 by bolts, and the overall structure of the ball-jointed module trolley 4 adopts a concave structure in the middle, thereby reducing the overall height of the ball-jointed support 3 fixed above it and increasing its stability.

[0048] A ball joint 34 is fixedly installed in the middle of the bottom end of the upper ball joint support 32, and the left and right ends of the ball joint 34 are integrally formed with an arc surface 35. A rotating slot 36 matched with the ball joint 34 is provided at the top of the lower ball joint support 31, and a clearance fit is formed between the ball joint 34 and the rotating slot 36. Fixed frames 37 are fixedly installed on both sides of the top of the lower ball joint support 31, and a fixed side block 38 is inlaid and installed inside the fixed frame 37. An oil injection channel 39 is provided on one side of the top of the fixed frame 37, and an absorption sponge 39A is fixedly installed on one side of the inner wall of the fixed frame 37. An arc filter plate 39B is provided on the side of the absorption sponge 39A, and the arc filter plate 39B has equidistant openings inside. A plurality of filter holes 39C are provided, and an arc-shaped notch 39D is provided on one side of the fixed side block 38 close to the arc-shaped filter plate 39B. The top end of the ball joint 34 protrudes out of the interior of the fixed frame 37. The overall curvature of the arc surface 35 increases from top to bottom, and the curvature of the arc surface 35 is greater than the overall curvature of the ball joint 34. The overall oil injection channel 39 is distributed in an inclined shape, and the inclination direction is inclined toward one side of the absorbing sponge 39A. The top shape of the fixed side block 38 is consistent with the inclination state of the oil injection channel 39, and the top end of the oil injection channel 39 is flush with the highest point of the top end of the absorbing sponge 39A. The overall curvature of the absorbing sponge 39A is smaller than the overall curvature of the arc surface 35, and the outer track length of the absorbing sponge 39A is 1.3mm. The length of the trajectory is less than the length of the outer side of the arc surface 35, the top side of the absorbing sponge 39A is connected to the end of the oil injection channel 39, the arc filter plate 39B is adapted to the shape of the absorbing sponge 39A, and one end of a plurality of the filter holes 39C is respectively connected to one side of the arc slot 39D, the overall shape of the arc slot 39D is arc-shaped, and the width of the arc slot 39D increases from top to bottom until the outlet position on the side in contact with the ball joint 34 reaches the maximum value, the absorbing sponge 39A, the arc filter plate 39B and one side of the fixed side block 38 are all in contact with the surface of the ball joint 34 and one side has the same shape as the surface shape of the ball joint 34, and the absorbing sponge 39A is in contact with the arc filter plate 39B except for the side of the absorbing sponge 39A. , a layer of rubber film soft layer is pasted on the other five surfaces, the top of the arc filter plate 39B is kept flush with the top of the arc slot 39D, and a plurality of arc protrusions 9 are sequentially arranged on the outer side surface of the arc surface 35 from top to bottom, and the spacing values ​​of the plurality of arc protrusions 9 decrease from top to bottom, and the inclination angle of the arc protrusions 9 is consistent with the curvature of the arc surface 35, and the central axis direction of the arc protrusion 9 when fixed always points to the vertical angle direction of the outer track of the outer track of the absorption sponge 39A, the overall shape of the arc protrusion 9 is semicircular, and the volume of the plurality of arc protrusions 9 decreases from top to bottom, and the track range between the arc protrusions 9 at the end of both ends of the arc surface 35 is equal to the outer track length of the absorption sponge;

[0049] First, when the operator adjusts the rotation angle and direction of the ball-jointed module trolley 4 through the ball-jointed support 3, the bottom ball-joint joint 34 of the upper ball-joint support 32 will first rotate in the rotating groove 36 to adjust its own angle and direction, and in the process of its adjustment, the arcuate surfaces 35 connected on both sides of the top of the ball-joint joint 34 will contact and squeeze the upper surface of the absorbing sponge 39A as the ball-joint joint 34 moves downward, and continue to press down, and by utilizing the difference in curvature between the two, the arcuate surface 35 can fully contact the outer side of the absorbing sponge 39A, and gradually apply pressure to its entire outer side surface, thereby gradually squeezing out the lubricating oil contained in it, and then separating it. The grease will pass through the filter holes 39C inside the arc filter plate 39B in turn, and drip into the arc slot 39D, and finally flow out from the opening at the bottom of one side thereof under the drainage effect of the arc slot 39D, and be guided to the surface of the ball joint 34, and gradually cover the surface of the ball joint 34 with the rotation effect of the ball joint 34 and the rotation slot 36, so as to achieve adaptive lubrication operation, and there is no need for the operator to repeatedly provide manual autonomous lubrication operation. In the process of rotating and adjusting the ball joint support 3, the lubrication process can be passively completed, which greatly improves the automation degree and efficiency of the device, and at the same time increases the use effect of the equipment;

[0050] When the arc surface 35 gradually squeezes to the upper surface of the absorbing sponge 39A and continues to press downward, the multiple arc-shaped protrusions 9 arranged in sequence on the arc surface 35 will synchronously contact the surface of the absorbing sponge 39A and squeeze it. At the same time, during the squeezing process, gaps are left between the multiple arc-shaped protrusions 9, so that a part of the absorbing sponge 39A as a whole is located within the gaps and is not completely compressed, so that the grease inside the absorbing sponge 39A is small in amount and gradually precipitated, thereby satisfying the lubrication effect of the ball joint 34 and the rotating groove 36 during the rotation process (a large amount of lubricating grease or rapid precipitation will cause the local sliding smoothness of the ball joint 34 to suddenly increase, thereby affecting the coordinated rotation effect of the ball joint 34 and the rotating groove 36. Therefore, in the actual lubrication process, it is necessary to add lubricating oil gradually and step by step).

[0051] The modular traveling hoisting trolley 6 includes a variable frequency speed regulating hoist 61, a sliding base 62 is fixedly installed at the bottom end of the variable frequency speed regulating hoist 61, a slider 63 is slidably mounted on the bottom end of the sliding base 62, the bottom end of the slider 63 is detachably mounted on the top end of the modular main beam 2, a fixed pulley block 64 is fixedly installed at the middle of the bottom end of the sliding base 62, a steel rope is wound around the surface of the fixed pulley block 64, and a movable pulley block 65 is arranged below the fixed pulley block 64 through the winding of the steel rope;

[0052] The top of the ball-jointed module trolley 4 is detachably mounted with a distribution beam 7, and the bottom of the distribution beam 7 is symmetrically mounted with four groups of ball-jointed module trolleys 4 on both sides, and the four groups of ball-jointed module trolleys 4 can rotate around their own centers, and the top of the distribution beam 7 is fixedly mounted with a hinge support 8;

[0053] One end of the steel rope is connected to the variable frequency speed regulating winch 61. There are multiple fixed pulley groups 64 and movable pulley groups 65. The multiple fixed pulley groups 64 and movable pulley groups 65 are connected by steel ropes. When the steel rope passes through the surface of one movable pulley group 65, it is connected to the next movable pulley group 65 through the bridge pulley.

[0054] There are four groups of modular walking lifting trolleys 6, and the four groups of modular walking lifting trolleys 6 are symmetrically arranged at the left and right ends of the modular main beam 2 respectively. The four groups of modular walking lifting trolleys 6 can be set as wheel-rail type modular walking lifting trolleys or hydraulic sliding type modular walking lifting trolleys. A transverse hydraulic cylinder is arranged on one side of the modular walking lifting trolley 6.

[0055] Among them, the main ball joint module trolley 4 has unique technical performance:

[0056] 1. Since the single-main ball-jointed module trolley 4 can rotate around its own center, under the guidance of the rails, it can travel on a curved track like a train;

[0057] 2. Since the ball joint inside the ball-jointed module trolley 4 has an automatic centering function, it can ensure that the force on it passes through the center of the ball-jointed module trolley 4 and can adapt to running on a track surface with poor conditions;

[0058] 3. Each ball-jointed modular trolley 4 can rotate 90° to achieve 90° vertical and horizontal travel.

[0059] For details, please refer to the attached manual Figure 4-5 and attached Fig.10 The bottom ends of the multiple sets of movable pulley groups 65 are all provided with hooks. After the multiple sets of hooks are fixed, the multiple sets of lifting points formed can realize four-change three-force by winding steel ropes, and the multiple sets of lifting point steel ropes are all moving trajectories of vertical lifting.

[0060] The specific implementation method is as follows: The principle of multi-degree-of-freedom precise and rapid positioning of three-dimensional gantry crane: its lifting system consists of four lifting points. Since multiple lifting points can realize centralized control, 1 to 4 lifting points can be controlled in any combination, each lifting point can be controlled individually to realize up and down, left and right movements, and the whole machine can realize forward and backward movement. It can better realize the precise and rapid positioning of multiple degrees of freedom of lifting heavy objects in high-altitude three-dimensional space, which can improve construction efficiency and safety and reliability. At the same time, since the steel rope of the multi-lifting point lifting is in a vertical state, the steel rope of the single hook is lifted in a triangular shape, which greatly reduces the height of the gantry crane.

[0061] For details, please refer to the attached manual Figure 2-4 A hydraulic and electrical control system is fixed on one side of the sliding base 62.

[0062] The specific implementation method is as follows: the variable frequency speed regulating hoist 61 and the sliding base 62 can be controlled by a control system through a transverse hydraulic cylinder provided on one side thereof, so as to realize synchronization and precise alignment functions.

[0063] Working principle of the present invention:

[0064] Step 1: First, the operator assembles the various components of the device normally, and then starts the device normally.

[0065] Step 2: First, install the bracket at the earthwork site at the bridge site, install the Bailey track beam 5 on the upper surface of the bracket, symmetrically install four sets of ball-jointed module trolleys 4 and ball-jointed supports 3 on both sides of the upper surface of the Bailey track beam 5, install the assembled portal frame 1 on the ball-jointed supports 3, and the assembled portal frame 1 and the four sets of ball-jointed module trolleys 4 form a force-bearing whole, then symmetrically install two sets of modular main beams 2 on the assembled portal frame 1, and then symmetrically install four sets of modular main beams 2 on the two sets of modular main beams 2 respectively. The modular walking hoisting trolley 6 is provided with a lifting wire rope wound around the fixed pulley block 64 and the movable pulley block 65, and then the electrical control system and the hydraulic system are respectively installed on the modular walking hoisting trolley 6. The four groups of ball-jointed modular trolleys 4 are the walking mechanism and the bearing device of the integral structure. The ball joints arranged inside the four walking wheels of each group of ball-jointed modular trolleys 4 can bear equal forces. The variable frequency motor of the walking mechanism can realize the slow alignment function of the four groups of ball-jointed modular trolleys 4 through the electrical control system. Each set of ball-jointed module trolleys 4 can be one trolley or two trolleys. The legs of the assembled gantry 1 are assembled from modular standard steel pipes, and their height is a multiple of the length of the standard steel pipe bracket. The modular main beam 2 on the assembled gantry 1 is assembled from multiple sets of modular Bailey plates. At the same time, a cross-connection is connected between the two Bailey main beams. The spacing between the two main beams can be changed at any time by adding Bailey plates as needed. The span of the assembled gantry 1 is a multiple of the standard length of 3m of the Bailey plate. Four frequency converters are used to adjust the height of the gantry 1. The high-speed winch 61, the movable pulley group 65 and the fixed pulley group 64, and the transverse hydraulic cylinder together constitute the lifting mechanism. The variable-frequency speed-regulating winch 61 and the transverse hydraulic cylinder can achieve synchronization and precise positioning functions through the control system. The above structures together constitute a three-dimensional gantry beam erecting crane, which is mainly controlled by the electrical control system through centralized remote control to achieve precise positioning in the longitudinal, transverse and height directions, thereby improving its beam erection accuracy and speed, thereby completing the work process of precise erection and lifting of the beam pieces.

[0066] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
