Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, in particular to a storage device for a boom section frame of a tower crane. Background Art

[0002] Tower cranes are also called tower cranes. Due to their large operating space, they are widely used in the vertical and horizontal transportation of materials in the field of housing construction, as well as the installation of building components. They usually mainly include a tower body, a climbing frame, a lifting arm, a balancing arm, a slewing seat, etc. The lifting arm is restricted by transportation and installation conditions, and can only be assembled and spliced ​​on site according to needs before use. As the construction site is restricted by the use environment, the tower crane's lifting arm sometimes cannot be installed at full arm as calibrated, and the arm must be reduced; the reduced lifting arm sections are stored in warehouses or yards for a long time. Over time, the number of remaining arm sections increases, and the storage site needs to be managed regularly, which is time-consuming and labor-intensive. Figure 1 , 2 As shown, the boom frame 10' mainly includes an upper chord 11', a lower chord 12' and a web 13' connected between the upper and lower chords. When storing the boom frame 10', the boom frame is usually laid horizontally in the yard and stacked together. The stacked boom frames are affected by the shape of the boom frame interface (triangle), and the safety and stability are extremely poor. They are very easy to slide and are dangerous, and it is inconvenient for stacking personnel to go up and down. In addition, due to the limited bearing capacity of the web in the boom frame, the boom frame can usually only be stacked in two or three layers, which takes up a lot of yard area and has a very low volume efficiency. In addition, when a specific boom frame is needed, it is very inconvenient to find it. If the boom frame stacked on the lower layer needs to be removed, a large amount of manpower and equipment are required to reverse the warehouse and restack it before the boom frame can be taken out, which is very inconvenient. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a storage device for the tower crane boom section frame which vertically stores the boom section frame in view of the problem that the horizontal storage method of the tower crane boom section frame in the prior art not only occupies a large yard area but is also inconvenient to search and transport.

[0004] The technical solution to the technical problem of the utility model is: constructing a storage device for a tower crane boom section frame, including a frame with multiple storage areas, a stepping mechanism fixed on the top of the frame and located around the corresponding storage areas, and an anti-tilt positioning claw detachably connected to the stepping mechanism, wherein the anti-tilt positioning claw is provided with a positioning groove matching the boom section frame chord.

[0005] Furthermore, the stepping mechanism includes a stepping frame, a stepping board covering the stepping frame and a railing fixedly arranged around the stepping frame; the anti-tilt positioning claw is detachably connected to the stepping frame; so that personnel can operate the anti-tilt positioning claw at the top of the frame.

[0006] Furthermore, the step frame is provided with a horizontal adjustment slot located in a horizontal plane, the anti-tilt positioning claw is provided with a horizontal adjustment rod matching the horizontal adjustment slot, the horizontal adjustment rod is slidably arranged in the horizontal adjustment slot, one end of the horizontal adjustment rod is fixedly connected to the positioning slot and the other end is detachably connected to a side of the step frame close to the corresponding storage area through a detachable fastener; so that by positioning the anti-tilt positioning claw at different positions of the horizontal adjustment slot of the step frame, arm sections of different specifications can be positioned in the corresponding storage areas within the frame.

[0007] Furthermore, there are multiple adjusting slide grooves, and the multiple adjusting slide grooves are arranged in the same horizontal plane to adapt to boom sections of different sizes.

[0008] Furthermore, a mounting opening is provided in the step frame, and the step plate is movably and removably covered on the mounting opening; it is convenient to install and disassemble the anti-tilt positioning claw through the mounting opening on the inner side of the step mechanism, further ensuring the safety of the operator.

[0009] Furthermore, the number of positioning grooves of the anti-tilt positioning claw is two or three, so as to reliably position adjacent boom sections together.

[0010] Furthermore, one side of the positioning groove is arranged as an open side so that the anti-tilt positioning claw can be sleeved on the chord rod of the corresponding boom section frame.

[0011] Furthermore, it also includes a movable positioning rod that can be detachably fixed on the frame, and the anti-roll positioning claw can be detachably connected to the side of the movable positioning rod facing the corresponding storage area; by adjusting the position of the movable positioning rod on the frame, the distance between the anti-roll positioning claw and the arm section frame in the corresponding storage area can be adjusted, thereby improving the applicability of the entire device.

[0012] Furthermore, the movable positioning rod is provided with a guide slot matching the frame, which makes it more convenient to adjust the relative position of the movable positioning rod on the frame.

[0013] Furthermore, a vertical adjustment slot is provided on the frame at the connection point corresponding to the movable positioning rod, a vertical adjustment rod is fixedly provided at the end of the movable positioning rod, the vertical adjustment rod is slidably arranged in the vertical adjustment slot, one end of the vertical adjustment rod is fixedly connected to the movable positioning rod and the other end is detachably connected to the vertical adjustment slot via a detachable fastener; this makes the assembly and disassembly of the movable positioning rod very convenient, and the position of the movable positioning rod can be quickly adjusted.

[0014] The storage device for the boom section frame of the tower crane described in the utility model has the following beneficial effects: by setting a plurality of storage areas in the frame, boom sections of different specifications can be stored vertically in the corresponding storage areas, which greatly improves the utilization rate of the site. Compared with the existing horizontal storage mode, the utilization rate per unit area is increased by more than three times. Since the boom section frame is stored vertically, the overall gravity of the boom section frame is borne by the ground of the corresponding storage area, and the frame only needs to provide lateral anti-tilt support force for each boom section frame, which reduces the strength requirement of the frame, thereby saving the production cost of the entire device. At the same time, for the boom section frame stored vertically, it is not necessary to move adjacent boom sections and repeatedly reverse the warehouse and re-stack them as in the horizontal storage method in the prior art. It is only necessary to disassemble the corresponding anti-tilt positioning claws and then hoist them, which is very convenient for searching and transporting. By setting a stepping mechanism at the top of the frame, it is convenient for personnel to perform hoisting, positioning, maintenance and other operations on the boom section frame on the stepping mechanism, and it provides great physiological and psychological protection for personnel, reducing the safety risks of high-altitude workers. Since the chord of the boom frame is located at the outer contour of the entire boom frame, by providing a positioning groove matching the chord of the boom frame on the anti-tilt positioning claw, the entire boom frame can be positioned in the corresponding storage area between the stepping mechanisms. The entire device has a simple structure, low manufacturing cost, convenient and safe use, and occupies a small area and is easy to call.

[0015] Furthermore, since the spacing between the upper and lower chords in the boom sections of crane arms of different specifications is different, the lateral dimension of the storage area can be adjusted by providing a movable positioning rod, so that boom sections of different specifications and sizes can be positioned, thereby increasing the scope of application of the device.

[0030] like Figure 2 As shown, in the preferred embodiment of the storage device of the tower crane boom section frame of the utility model, in order to facilitate a clearer description of the embodiment of the utility model, the web rod inside the boom section frame is omitted and simplified. In this preferred embodiment, the boom section frame 10 also includes an upper chord rod 11, a lower chord rod 12 and a web rod 13 connected and supported between the upper and lower chord rods.

[0031] like Figure 3 , 4 As shown in Figures 5, 5a, 6, 7a, 7b and 8, in a preferred embodiment of the storage device for the boom section frame of a tower crane of the utility model, the storage device comprises a frame 20, a stepping mechanism 30 and an anti-tilt positioning claw 40. The stepping mechanism 30 is fixedly arranged on the top of the frame 20, and the anti-tilt positioning claw 40 is detachably connected to the stepping mechanism 30.

[0032] like Figure 3 , 4 As shown, in this preferred embodiment, the frame 20 is connected by a crossbar 21, a longitudinal bar 22 and a vertical bar 23. Preferably, a reinforcing bar 24 is arranged between the crossbar 21 and the vertical bar 23 and between the longitudinal bar 22 and the vertical bar 23. The reinforcing bar 24 can be arranged horizontally, vertically or inclined. In this preferred embodiment, the entire frame 20 is divided into four storage areas 25 by the crossbar 21 and the longitudinal bar 22. Specifically, the frame can be divided into more storage areas according to actual needs.

[0033] like Figure 3 , 5As shown in Figures 5a and 5a, in the preferred embodiment, the stepping mechanism 30 is arranged at the top of the frame 20 at a position around the corresponding storage area 25. The stepping mechanism 30 is preferably arranged to include a stepping frame 31, a stepping board 32 and a railing 33. Specifically, the stepping frame 31 may include at least two longitudinal beams 31a parallel to each other and a crossbeam 31b connected between two adjacent longitudinal beams 31a, and both ends of the longitudinal beam 31a are fixed to the crossbar 21 of the frame by fasteners such as bolts 31c. The stepping board 32 covers the stepping frame 31. Specifically, the stepping board 32 may be embedded between two adjacent longitudinal beams 31a. In the preferred embodiment, it is preferred to set an installation opening 34 in the stepping frame 31, and set the stepping board 32 to movably and removably cover the installation opening 34. Specifically, the gap between two adjacent beams 31b is the installation opening 34. The stepping board 32 is split into multiple pieces, each of which is embedded in the corresponding beam 31b, so that it can be movably and detachably covered on the installation opening 34. When it is necessary to operate in the corresponding installation opening 34, the corresponding stepping board 32 can be removed; during normal use, the stepping board 32 is supported by the corresponding beam 31b to prevent the operator from stepping on empty space, further ensuring the safety of the operator. In this preferred embodiment, the stepping board 32 can be set to a hollow grid shape. The railing 33 is fixedly set around the stepping frame to form a safe enclosure for the operator.

[0034] like Figure 5 As shown, in this preferred embodiment, the stepping mechanism 30 is preferably arranged to include a longitudinal stepping mechanism 30a arranged on the frame longitudinal rod 22 and a transverse stepping mechanism 30b arranged on the frame transverse rod 21, wherein the longitudinal stepping mechanism 30 and the transverse stepping mechanism 30 are arranged crosswise, and the crossed stepping mechanisms 30 are interconnected to ensure that each storage area 25 can be reached by a corresponding stepping mechanism 30. Specifically, the railings 33 of all the stepping mechanisms are interconnected and connected to form a whole at the intersection, and the stepping frames 31 of all the crossed stepping mechanisms are fixedly connected together by fasteners such as bolts.

[0035] The boom sections 10 may be arranged longitudinally or transversely in each corresponding storage area 25 as required, or the boom sections 10 may be arranged in different directions in each storage area 25. Figure 3 , 8 As shown, in this preferred embodiment, the boom section frames 10 are preferably arranged longitudinally in each corresponding storage area 25, and a longitudinal stepping mechanism 30a matching the length of the storage area 25 is provided on the two longitudinal rods 22 corresponding to each storage area 25, and the anti-tilt positioning claws 40 are detachably connected to the longitudinal stepping mechanism 30a to ensure that each boom section frame 10 has three anti-tilt positioning claws 40 cooperating with its chord rod.

[0036] Since the cross-sectional shape of the boom frame 10 is usually set to be triangular, when stored vertically, the boom frame 10 can be staggered so that the upper chords 11 and lower chords 12 of two adjacent boom frames are crossed and arranged in parallel, that is, the upper chord 11 of the first boom frame is side by side with the lower chord 12 of the second boom frame, and the lower chord 12 of the first boom frame is side by side with the upper chord 11 of the second boom frame, so as to save space in the storage area 25.

[0037] like Figure 7a , 8 As shown, in this preferred embodiment, the anti-tilt positioning claw 40 includes a positioning groove 41 and a horizontal adjustment rod 42; wherein the positioning groove 41 matches the chord rods 11 and 12 of the boom frame. Specifically, the cross-sectional shape of the upper and lower chord rods 11 and 12 of the boom frame is usually set to a rectangular shape, and the cross-sectional shape of the positioning groove is correspondingly set to a rectangular shape, and one side of the positioning groove is an open side 43. One end of the horizontal adjustment rod 42 is fixedly set on the outer side of the groove wall of the fixed side 44 of the positioning groove, and the fixed side 44 is set to be opposite to the open side 43. It is best to set the horizontal adjustment rod 42 perpendicular to the groove wall of the fixed side 44. The other end of the horizontal adjustment rod 42 is detachably connected to the side of the step frame close to the corresponding storage area 25 through a detachable fastener. Specifically, the other end of the horizontal adjustment rod 42 can be fixed to the longitudinal beam 31a of the step frame through a fastener such as a nut. At this time, when the horizontal adjustment rod 42 of the anti-tilt positioning claw is fixed to the step mechanism 30, the open side 43 of the positioning groove faces the storage area 25.
