Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a tower crane cable fixing device. Background Art

[0002] Tower cranes are commonly used equipment in high-rise building construction. At present, technicians pay more attention to the fixing of cables. Cables are indispensable due to the needs of power supply, communication and control. In order to avoid the downward pull of the cable's own weight and strong winds, which may cause scratches and wear between the cable and the standard section of the tower crane and the cables, and to avoid safety accidents such as power failure and leakage, tower crane cable fixing devices are installed at certain heights.

[0003] The traditional tower crane cable fixing device generally fixes multiple porcelain bottles on the standard section of the tower crane, and then uses insulating ties to tie multiple parallel cables to their respective porcelain bottles one by one. The tower crane needs to be lifted in stages. For example, if it is 20 stories high, the height is generally determined to be five stories for the first time, and then it is generally raised every five stories, such as ten stories, fifteen stories, and twentieth stories. Multiple cables, such as five cables, are also lifted with the lifting of the cab. The shortcomings of the traditional tower crane cable fixing device are obvious: before each lifting, workers need to untie the insulating ties of each cable one by one from the standard section to the tenth floor. After lifting in place, such as from the fifth to the tenth floor, workers need to re-tie each cable one by one from the standard section to the standard section. Each untying or tying is very inconvenient, time-consuming and labor-intensive, and the efficiency of fixing the cable is low.

[0004] In recent years, technicians in this field have designed more tower crane cable fixing devices. Compared with traditional tower crane cable fixing devices, there is no need to tie or disassemble cables one by one, which is relatively labor-saving and relatively improves the efficiency of fixing cables. However, the tower crane cable fixing devices in the prior art still have the following shortcomings: such as relatively complex structure, relatively high device cost, the device itself is relatively delicate and easy to damage, and the stability and reliability of fixing cables are still not ideal, etc., and there is still a lot of room for improvement. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a tower crane cable fixing device which has a relatively simple structure, is easy to operate and has good stability and reliability in fixing the cable.

[0006] The technical solution of the utility model is to provide a tower crane cable fixing device, including a long strip buckle base plate fixed on the tower crane standard section; the long strip buckle base plate is provided with a plurality of elastic buckles corresponding to each other to fix each vertical cable, and the outer sides of the openings of the plurality of elastic buckles are provided with a brake rod to prevent the vertical cables from being laterally disengaged from the elastic buckles, one end of the brake rod is hinged to the standard section, and the other end of the brake rod is detachably connected to the standard section.

[0007] After adopting the above structure, the utility model has the following advantages: it can effectively avoid the downward pulling force of the cable's own weight and strong winds, which cause scratches and wear between the cable and the standard section of the tower crane and the cables each other, so as to avoid safety accidents such as power outages and leakages; and during the lifting process of the standard section, the disassembly and fixation of the cable is relatively labor-saving, and the work efficiency of fixing the cable is relatively improved.

[0008] In particular, the utility model of the tower crane cable fixing device has a relatively simple structure and a relatively low device cost. When multiple vertical cables of each standard section need to be fixed, it is only necessary to insert multiple elastic buckles into each corresponding vertical cable, and then fix the long strip buckle base plate with the standard section, and then lower the gate rod around the hinge axis, and make the gate rod and the standard section detachably connected, which is very convenient to operate. Moreover, the stability, reliability and firmness of fixing the vertical cable are good, the device itself is not easy to be damaged, the service life is relatively long, the buckle effect on the vertical cable is good, and the practicality is strong.

[0009] Furthermore, a hinge block is fixed at one end of the long strip buckle base plate, the thickness of the hinge block is greater than the thickness of the elastic buckle, a first screw is screwed on the hinge block, one end of the gate rod is rotated through the hinge hole to fit on the first screw and can be fastened by the first screw, the inner surface of the other end of the gate rod is pressed against a fixed block fixed on the other end of the long strip buckle base plate through an elastic plate, and the thickness of the fixed block is also greater than the thickness of the elastic buckle. After the gate rod and the standard section are detachably connected using the above specific structure, if multiple vertical cables need to be disassembled, it is only necessary to loosen the first screw and then rotate the gate rod upward around the first screw. After multiple vertical cables are inserted, it is necessary to prevent multiple vertical cables from being laterally disengaged from the elastic buckle, and it is only necessary to rotate downward around the first screw to make it horizontal and the other end is pressed against the fixed block through an elastic plate and the first screw is tightened. The technical effect of convenient operation, good clamping effect on vertical cables and strong practicality is further guaranteed.

[0010] Furthermore, the thickness of the fixed block is greater than that of the hinge block, and the other end of the gate rod is bent outward in an S shape. With the above structure, the gate rod detachable connection has good reliability and stability, and the gate rod is ensured not to interfere with the outer side of the elastic buckle during the upward or downward rotation, further ensuring the convenience of operation.

[0011] Furthermore, a first threaded hole is provided on the fixing block, and a screw through hole is provided on the part where the elastic plate and the other end of the gate rod are in contact with the elastic plate, and a second screw can be screwed into the first threaded hole. With the above structure, a double insurance function is achieved, and the detachable connection between the other end of the gate rod and the fixing block is more reliable and more stable, so that the gate rod can prevent multiple vertical cables from being laterally disengaged from the elastic buckle, further ensuring the good buckle effect and strong practicality of the vertical cable buckle.

[0012] Furthermore, the structure of the elastic buckle is as follows: each elastic buckle includes a triangular inner seat fixed to the long strip buckle substrate. At the openings of the two symmetric plates of the triangular inner seat, there is a semi-circular hoop with a diameter smaller than the diameter of the vertical cable to be clamped and used for clamping the vertical cable. On the outer side of the semi-circular hoop, there is an arc-shaped opening formed by two outward curling edges for the horizontal entry and exit of the vertical cable. There is a first support plate on the bottom plate of each triangular inner seat and the semi-circular hoop. The bottom plates of multiple triangular inner seats are fixed to form an integral plate in the same straight line. After the elastic buckle adopts the above specific structure, it has better elasticity, and the clamping of the vertical cable is firmer, more stable and more reliable.

[0013] Furthermore, the first support plate is located in the middle of the width of each triangular inner seat. After adopting the above structure, the mechanical properties of the elastic buckle are better, and the clamping of the vertical cable is firmer, more stable and more reliable.

[0014] Furthermore, there is a second support plate parallel to the integral plate in the same straight line between every two triangular inner seats. After adopting the above structure, the mechanical properties of the elastic buckle are better, and the clamping of the vertical cable is firmer, more stable and more reliable.

[0015] Furthermore, on the integral plate in the same straight line and the long strip buckle substrate, there are multiple first bolts and first nuts for fixing the integral plate in the same straight line and the long strip buckle substrate. After adopting the above structure, the first bolts are located on the bottom plate (i.e., the integral plate) far from the elastic buckle, that is, far from the vertical cable, which not only ensures the integrity and insulation of the vertical cable, but also makes the connection between the elastic buckle and the long strip buckle substrate convenient, fast and firmly reliable.

[0016] Furthermore, the long strip buckle substrate is hung on a cross bar of the tower crane standard section through a C-shaped block with an opening facing down at each end, and is tightened by respective second bolts and second nuts. After adopting the above structure, the fixing structure of the long strip buckle substrate and the tower crane standard section is simple, the connection is convenient, fast and firmly reliable.

[0017] Furthermore, the tightening structure of the respective second bolts and second nuts is as follows: the inner dimension of each C-shaped block is larger than the thickness dimension of the rectangular cross bar to be hung. The second nuts are fixed on the side surfaces of the two ends of the long strip buckle substrate far from the C-shaped blocks. The second bolts are screwed into the second threaded holes of the second nuts, the third threaded holes at one end of the long strip buckle substrate and the fourth threaded holes on the outer vertical plates of the C-shaped blocks, and are tightened against a cross bar of the tower crane standard section. After adopting the above structure, the connection between the long strip buckle substrate and the tower crane standard section is more convenient, faster and more firmly reliable.

DETAILED DESCRIPTION

[0028] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these specific implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical means involved in each specific implementation method of the present invention described below can be combined with each other as long as there is no conflict between them.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown.

[0030] The standard section 1 of the prior art tower crane is generally a rectangular frame composed of a plurality of horizontal bars 11, a plurality of vertical bars 12 and a plurality of diagonal braces 13. The horizontal bars 11 are also called transverse keels, the vertical bars 12 are also called vertical keels, and the diagonal braces 13 are also called diagonal bars. Generally, each standard section 1 is provided with a set of tower crane cable fixing devices.

[0031] The utility model tower crane cable fixing device 3 comprises a long strip buckle base plate 35 fixed on the tower crane standard section 1. The long strip buckle base plate 35 has a plurality of elastic buckles 32 corresponding to each other to fix each vertical cable 2, and the outer side of the opening 3262 of the plurality of elastic buckles 32 is provided with a brake rod 33 to prevent the vertical cable 2 from being laterally disengaged from the elastic buckle 32, one end of the brake rod 33 is hinged to the standard section 1, and the other end of the brake rod 33 is detachably connected to the standard section 1.

[0032] The specific structure of hinged connection between one end of the gate rod 33 and the standard section 1 can be as follows: a hinge block 34 is fixed to one end of the long strip buckle base plate 35, such as welded, the thickness of the hinge block 34 is greater than the thickness of the elastic buckle 32, a first screw 31 is screwed on the hinge block 34, one end of the gate rod 33 is rotated and sleeved on the first screw 31 through a hinge hole, such as a first screw through hole 331, and can be fastened by the first screw 31, the inner surface of the other end of the gate rod 33 is pressed against a fixed block 36 fixed to the other end of the long strip buckle base plate 35, such as welded, through an elastic plate 37, such as a rubber plate, the elastic plate 37 can be fixed to the fixed block 36, such as glued, and the thickness of the fixed block 36 is also greater than the thickness of the elastic buckle 32. A first screw 31 is screwed on the hinge block 34, such as a fifth threaded hole 341 is provided on the hinge block 34, and the first screw 31 is screwed into the fifth threaded hole 341. It is easy to understand that the thickness of the elastic buckle 32 refers to the dimension of each elastic buckle 32 from the inner side surface of the bottom plate 324 attached to the long strip buckle base plate 35 to the outer side surface close to the gate rod 33, such as the outer side surface of the two-way outward curling edge 3231.

[0033] The thickness of the fixing block 36 may be greater than the thickness of the hinge block 34 , and the other end of the gate rod 33 may be bent outwardly in an S-shape 333 .

[0034] The specific structure of the other end of the gate rod 33 being detachably connected to the standard section 1 may be as follows: a first threaded hole 361 may be provided on the fixing block 36, and screw holes may be provided on the elastic plate 37 and the part where the other end of the gate rod 33 is attached to the elastic plate 37, such as a second screw hole 371 is provided on the elastic plate, and a third screw hole 332 may be provided on the part where the other end of the gate rod 33 is attached to the elastic plate 37, and a second screw 38 can be screwed into the first threaded hole 361. It is not difficult to understand that the second screw 38 can be screwed into the first threaded hole 361 after passing through the second screw hole 371 and the third screw hole 332. It is also possible not to screw in the second screw 38, because the above-mentioned abutting structure has enabled the other end of the gate rod 33 to be stably and detachably fixed to the fixing block 36. Of course, it is preferred to screw in the first threaded hole 361 with the second screw 38, which can play a double insurance role.

[0035] The above-mentioned tightening can be expressed as one end of the gate rod 33 can be tightened and fixed by the first screw 31 when the gate rod 33 is located outside multiple elastic buckles 32, such as five, and the first screw 31 is loosened when the gate rod 33 needs to be rotated. The above-mentioned tightening can be expressed as the second screw 38 can be tightened in the first threaded hole 361, with double insurance, both tightening and threading, so that the other end of the gate rod 33 can be more stably fixed to the fixing block 36 in a detachable manner, and the second screw 38 can be screwed out when the gate rod 33 needs to be detached from the fixing block 36.

[0036] The specific structure of the elastic buckle 32 is preferably as follows: each elastic buckle 32 includes a triangular inner seat 322 fixed to the long strip buckle base plate 35, a multi-semicircular clamp 323 with a diameter smaller than the diameter of the clamped vertical cable 2 and used to clamp the vertical cable 2 is fixed at the opening of the two symmetrical plates 3221 of the triangular inner seat 322, and the outer side of the multi-semicircular clamp 323 is provided with an arc opening 3232 composed of two outward curling edges 3231 and for the vertical cable 2 to enter and exit horizontally, and a first support plate 325 is provided on the bottom plate 324 of each triangular inner seat 322 and the multi-semicircular clamp 323. The inner end of each triangular inner seat 322 can be wider than the outer end. The bottom plates 324 of multiple, such as five, triangular inner seats 322 are fixed to each other as an integral plate 326 in the same straight line. It is not difficult to understand that the multi-semicircular clamp 323 is larger than the semicircular clamp but smaller than the circular clamp.

[0037] The first support plate 325 is preferably located in the middle of the width of each triangular inner seat 322 .

[0038] There is preferably a second support plate 327 parallel to the same straight line of the integral plate 326 between each two triangular inner seats 322 .

[0039] On the integral plate 326 and the strip-shaped buckle substrate 35 on the same straight line, there are multiple, such as two first bolts 39 and two first nuts 310, for fixing the integral plate 326 and the strip-shaped buckle substrate 35 on the same straight line. It is not difficult to understand that after the first bolt 39 passes through the respective first bolt through holes 352 on the strip-shaped buckle substrate 35 and the bolt through holes (not shown in the figure) on the bottom plate 324 at both ends of the integral plate 326 on the same straight line, the first nut 310 is screwed tightly. Of course, the multiple can also be three, four, etc. The bottom plate 324 is also called the inner plate.

[0040] The strip-shaped buckle substrate 35 can be fixed, such as by welding, and each of the two downward-opening or downward C-shaped blocks 311 at both ends is hung on a cross bar 11 of the standard section 1 of the tower crane, and is fixed tightly by the respective second bolts 312 and second nuts 313.

[0041] The tightening structure of the respective second bolts 312 and second nuts 313 is preferably: the inner dimension of each C-shaped block 311 is larger than the thickness dimension of the rectangular cross bar 11 to be hung. The second nuts 313 are fixed, such as by welding, on the sides of the strip-shaped buckle substrate 35 away from the C-shaped blocks 311 at both ends. The second bolts 312 are screwed into the second threaded holes 3131 of the second nuts 313, the third threaded holes 351 of the strip-shaped buckle substrate 35, and the fourth threaded holes 31111 of the outer vertical plates 3111 of the C-shaped blocks 311, and are tightened against a cross bar 11 of the tower crane standard section. To increase the contact area, a disc, such as a conical disc, can be spot-welded on the free end of the second bolt 312 protruding from the outer vertical plate 3111 of the C-shaped block 311.

[0042] The above-mentioned clamping can also be called clamping or fastening.

[0043] The components, structures, quantities, etc. not marked above are not shown in the figure, and some components are not marked in the figure. The drawings are only schematic. If there are inconsistencies between the drawings and the text description, or inconsistencies between the drawings themselves, the text description shall prevail.

[0044] The above is only the preferred embodiment of the present invention and is not used to limit the present invention.
