Description

Technical Field

[0001] The invention relates to the technical field of combined crane main beams, and in particular to a freely combinable combined crane main beam and an assembly method. Background Art

[0002] Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. They are widely used in outdoor places such as port cargo yards. The main beam of the crane, as the main component of the load, is used to lift the cargo. The main beams of existing cranes have inherent sizes when they leave the factory and cannot be freely combined according to the requirements of the lifting span size, thus failing to meet different usage requirements and affecting the efficiency of cargo lifting. Therefore, a freely combinable modular crane main beam and combination method are designed here to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a freely combinable modular crane main beam and an assembly method to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a freely combinable modular crane main beam, comprising a plurality of freely combinable main beams and connecting parts, wherein the plurality of main beams are distributed in a straight line structure, and a traveling frame is fixedly provided at the end of the outermost main beam. The number of main beams is selected according to usage requirements, and then the selected main beams are distributed in a straight line structure to facilitate assembly into a main beam for use, and the main beam is erected by the traveling frame for use in lifting cargo.

[0005] Two adjacent main beams can be detachably connected through connecting parts to be assembled into a complete main beam for lifting cargo to meet lifting needs.

[0006] The connecting piece includes a docking seat and a connecting plate. Both side walls of the docking seat are fixed with connecting rods. Both side walls of the main beam are provided with connecting grooves for sliding connection with the connecting rods. The connecting plate is fixedly arranged on the upper end surface of the docking seat. The docking seat is placed between two adjacent main beams, and then the connecting rod is inserted into the connecting groove to dock the two main beams. The main beams are connected by inserting the connecting rod into the connecting groove, and the connecting rod can be used to enhance the supporting strength of the main beam.

[0007] The bottom end surface of the connecting plate fits with the upper end surfaces of two adjacent main beams, so that after the plug-in rod is inserted into the plug-in groove, the connecting plate is pressed onto the upper end surface of the main beam to avoid bending deformation of the main beam.

[0008] In a further embodiment, a roller is rotatably provided at the bottom end of the traveling frame, a driving motor is fixedly provided at the top end of the side wall of the traveling frame, a power shaft of the driving motor is connected to the roller, and the driving motor provides power to drive the roller to rotate, thereby facilitating the traveling frame to move along a preset track, thereby driving the main beam to move along the track, thereby realizing the longitudinal transfer operation of the goods.

[0009] In a further embodiment, a first T-shaped slide groove is provided at the bottom end of the main beam, and a second T-shaped slide groove is provided at the bottom end of the docking seat. The docking seat is fitted with two adjacent main beams, and the first T-shaped slide groove is docked with the second T-shaped slide groove. The driving device used for lifting cargo is slidably installed in the first T-shaped slide groove of the main beam, and can slide horizontally along the first T-shaped slide groove, slide across the first T-shaped slide groove into the second T-shaped slide groove, and then enter the first T-shaped slide groove again, thereby realizing the lateral transfer operation of cargo along the horizontal end of the assembled main beam.

[0010] In a further embodiment, semicircular threaded columns are vertically fixed on both sides of the upper end of the connecting plate. After two adjacent connecting plates are butt-jointed together, the two opposite semicircular threaded columns form a cylindrical threaded column. The outer walls of the assembled cylindrical threaded columns can be plugged together using an external nut, so that the two adjacent connecting plates can be butt-jointed, thereby preventing the plug-in rod of the docking seat from detaching from the plug-in groove of the main beam, thereby enhancing the connection stability between the two adjacent main beams.

[0011] In a further embodiment, a positioning mechanism is provided at the upper end of the walking frame, and the positioning mechanism includes a positioning sleeve. A reinforcing mechanism is provided between the positioning sleeve and the cylindrical threaded column. The positioning sleeve and the cylindrical threaded column are connected by the reinforcing mechanism, so as to enhance the hoisting stability of the main beam when hoisting cargo, and avoid irreversible bending deformation of the assembled main beam due to the gravity of the cargo, thereby affecting the normal use and operation of the crane.

[0012] In a further embodiment, the radial side wall of the positioning sleeve is provided with a plurality of axially distributed installation notches connected to the interior of the positioning sleeve, the reinforcement mechanism includes a threaded sleeve and a pull rod, and hinged seats are fixed at both axial ends of the pull rod, one of the hinged seats is hinged to the side wall of the threaded sleeve, the threaded sleeve is stuck in the installation notch, and a threaded adjustment rod extending to the interior of the positioning sleeve is rotatably inserted at the top end of the positioning sleeve, and the threaded adjustment rod is rotated to penetrate the threaded sleeve installed in the installation notch, and the pull rod is used as a linkage medium to insert the threaded sleeve into the installation notch of the positioning sleeve, and then the threaded adjustment rod can be rotated by hand to screw the threaded adjustment rod into the threaded sleeve, thereby fixing the threaded sleeve in the installation notch and connecting the reinforcement mechanism with the positioning mechanism.

[0013] In a further embodiment, a pin is hinged on another hinged seat, and a threaded cap is rotatably provided on the bottom end of the pin. The threaded cap is rotatably sleeved on the outer wall of a cylindrical threaded column composed of two adjacent semicircular threaded columns. The threaded cap and the cylindrical threaded column composed of two adjacent semicircular threaded columns are rotatably inserted into each other, and the reinforcing mechanism can be connected to the main beam by rotatably inserting the threaded cap into the cylindrical threaded column composed of two adjacent semicircular threaded columns. Finally, the assembled main beam can be obliquely pulled up by utilizing the reinforcing mechanism, thereby enhancing the supporting strength of the main beam and avoiding irreversible bending deformation during the lifting process.

[0014] In a further embodiment, a socket is fixedly provided on the radial side wall of the threaded nut, and a plug-in interface for inserting a crowbar is opened on the socket. When the threaded nut is plugged into the cylindrical threaded column, the crowbar can be inserted into the plug-in interface of the socket to assist in rotating the threaded nut, so as to quickly put the threaded nut on the outer wall of the cylindrical threaded column.

[0015] Preferably, the method for assembling the freely combinable modular crane main beam described above comprises the following steps:

[0016] A1. Select the number of main beams according to the use requirements, and then distribute the selected main beams in a straight line structure. Two adjacent main beams can be detachably connected through connectors to assemble a complete main beam for hoisting goods to meet the hoisting requirements;

[0017] A2. Place the docking seat between two adjacent main beams, and then insert the plug-in rod into the plug-in slot to dock the two main beams. Connect the main beams by inserting the plug-in rod into the plug-in slot. The plug-in rod can be used to enhance the supporting strength of the main beams.

[0018] A3. By strengthening the mechanism to connect the positioning sleeve and the cylindrical threaded column, the hoisting stability of the main beam when hoisting goods can be enhanced, and the assembled main beam can be prevented from undergoing irreversible bending deformation due to the gravity of the goods, which would affect the normal use and operation of the crane.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention selects the number of main beams according to usage requirements, and then distributes the selected main beams in a straight-line structure. The two adjacent main beams are then detachably spliced ​​through connecting pieces to be assembled into a complete main beam for hoisting cargo to meet hoisting usage requirements. In addition, the strengthening mechanism and the positioning mechanism can be used to further enhance the connection stability between the two adjacent main beams, while enhancing the supporting strength of the main beam during hoisting, making it less susceptible to irreversible bending deformation caused by hoisting cargo, thereby meeting hoisting usage requirements.

DETAILED DESCRIPTION

[0027] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] See also Figure 1 , Figure 3 and Figure 4 This embodiment provides a freely combinable assembled crane main beam and an assembly method, including a plurality of freely combinable main beams 1 and connectors 2, wherein the plurality of main beams 1 are arranged in a straight line structure, and a traveling frame 5 is fixed at the end of the most side main beam 1. The number of main beams 1 is selected according to the use requirements, and then the selected main beams 1 are arranged in a straight line structure to facilitate assembly into the main beam 1 for use. The traveling frame 5 is used to erect the main beam 1 for hoisting cargo.

[0030] A first T-shaped slot 11 is provided at the bottom end of the main beam 1, and a second T-shaped slot 25 is provided at the bottom end of the docking seat 22. The docking seat 22 fits with two adjacent main beams 1, and the first T-shaped slot 11 is docked with the second T-shaped slot 25. The driving device used for lifting goods is slidably installed in the first T-shaped slot 11 of the main beam 1, and can slide horizontally along the first T-shaped slot 11, slide across the first T-shaped slot 11 into the second T-shaped slot 25, and then enter the first T-shaped slot 11 again, thereby realizing the lateral transfer operation of the goods along the horizontal end of the assembled main beam 1.

[0031] A roller 51 is rotatably provided at the bottom end of the traveling frame 5, and a driving motor 52 is fixedly provided at the top end of the side wall of the traveling frame 5. The power shaft of the driving motor 52 is connected to the roller 51. The driving motor 52 provides power to drive the roller 51 to rotate, thereby facilitating the traveling frame 5 to move along a preset track, thereby driving the main beam 1 to move along the track, thereby realizing the longitudinal transfer operation of the goods.

[0032] Two adjacent main beams 1 can be detachably connected through the connecting piece 2 to be assembled into a complete main beam 1 for hoisting goods to meet the hoisting requirements.

[0033] The connecting member 2 includes a docking seat 22 and a connecting plate 21. The side walls of the docking seat 22 are fixed with plug-in rods 23. The side walls of the main beam 1 are provided with plug-in grooves 12 for sliding plugging with the plug-in rods 23. The connecting plate 21 is fixedly arranged on the upper end surface of the docking seat 22. The docking seat 22 is placed between two adjacent main beams 1, and then the plug-in rod 23 is inserted into the plug-in groove 12 to dock the two main beams 1. The main beams 1 are connected by inserting the plug-in rod 23 into the plug-in groove 12, and the plug-in rod 23 can be used to enhance the supporting strength of the main beam 1.

[0034] Embodiment 2

[0035] See also Figure 1 , Figure 2 and Figure 5 , further improvements were made on the basis of Example 1:

[0036] Semicircular threaded columns 24 are vertically fixed on both sides of the upper end of the connecting plate 21. After the two adjacent connecting plates 21 are butt-jointed together, the two semicircular threaded columns 24 facing each other form a cylindrical threaded column. The outer walls of the assembled cylindrical threaded columns can be plugged together using an external nut, so that the two adjacent connecting plates 21 can be butt-jointed, thereby preventing the plug-in rod 23 of the docking seat 22 from detaching from the plug-in groove 12 of the main beam 1, thereby enhancing the connection stability between the two adjacent main beams 1.

[0037] In order to further enhance the connection stability between two adjacent main beams 1, a positioning mechanism 4 is provided at the upper end of the walking frame 5. The positioning mechanism 4 includes a positioning sleeve 41. A reinforcing mechanism 3 is provided between the positioning sleeve 41 and the cylindrical threaded column. The positioning sleeve 41 and the cylindrical threaded column are connected by the reinforcing mechanism 3, so as to enhance the hoisting stability of the main beam 1 when hoisting goods, thereby avoiding the irreversible bending deformation of the assembled main beam 1 due to the influence of the gravity of the goods, thereby affecting the normal use and operation of the crane.

[0038] The radial side wall of the positioning sleeve 41 is provided with a plurality of axially distributed mounting notches 42 connected to the interior of the positioning sleeve 41. The reinforcing mechanism 3 includes a threaded sleeve 33 and a pull rod 31. Both axial ends of the pull rod 31 are fixed with hinge seats 32, one of which is hinged to the side wall of the threaded sleeve 33. The threaded sleeve 33 is stuck in the mounting notch 42. A threaded adjustment rod 43 extending to the interior of the positioning sleeve 41 is rotatably inserted at the top of the positioning sleeve 41. The threaded adjustment rod 43 rotates and penetrates the threaded sleeve 33 installed in the mounting notch 42. The pull rod 31 is used as a linkage medium to insert the threaded sleeve 33 into the mounting notch 42 of the positioning sleeve 41. Then, the threaded adjustment rod 43 is rotated by hand to screw the threaded adjustment rod 43 into the threaded sleeve 33, thereby fixing the threaded sleeve 33 in the mounting notch 42 and connecting the reinforcing mechanism 3 with the positioning mechanism 4.

[0039] A pin shaft 35 is hinged on another hinged seat 32, and a threaded cap 34 is rotatably provided at the bottom end of the pin shaft 35. The threaded cap 34 is rotatably sleeved on the outer wall of a cylindrical threaded column composed of two adjacent semicircular threaded columns 24. By rotatably inserting the threaded cap 34 and the cylindrical threaded column composed of two adjacent semicircular threaded columns 24, the reinforcing mechanism 3 can be connected to the main beam 1, and finally the assembled main beam 1 is obliquely pulled up by the reinforcing mechanism 3, thereby enhancing the supporting strength of the main beam 1 and avoiding irreversible bending deformation during the lifting process.

[0040] Since the threaded sleeve 33 is hinged to the hinged seat 32, and the other hinged seat 32 is hinged to the threaded cap 34, different angles can be generated between the pull rod 31 according to different connection positions, so that the main beam 1 is always in a horizontal state, so that the main beam 1 can be used to lift goods.

[0041] Embodiment 3

[0042] See also Figure 1 and Figure 4 , further improvements were made on the basis of Example 2:

[0043] The bottom end surface of the connecting plate 21 is fitted with the upper end surfaces of two adjacent main beams 1 so that after the plug-in rod 23 is inserted into the plug-in groove 12, the connecting plate 21 is pressed against the upper end surface of the main beam 1 to prevent the main beam 1 from bending and deformation.

[0044] A plug-in seat 36 is fixedly provided on the radial side wall of the threaded cap 34, and a plug-in interface for inserting a crowbar is opened on the plug-in seat 36. When the threaded cap 34 is plugged into the cylindrical threaded column, the crowbar can be inserted into the plug-in interface of the plug-in seat 36 to assist in rotating the threaded cap 34 so as to quickly put the threaded cap 34 on the outer wall of the cylindrical threaded column.
