Description

Technical Field

[0001] This application relates to the field of cable fixing technology, and in particular to a tower crane cable insulation fixing device. Background Technology

[0002] Tower cranes, as important vertical transportation equipment, are widely used in various construction projects. Cables, as indispensable power transmission components during tower crane operation, are crucial for their safe and reliable arrangement. In related technologies, cable clamps are typically used to fix the cables along the tower body. A cable clamp includes a mounting base fixed to the tower body, a clamping body mounted on the mounting base for cable fixation, and a fastening mechanism for securing the clamping body to the mounting base. The mounting base is usually a fixed steel structure. By arranging the mounting base on the tower body and fixing it with the fastening mechanism, a fixed connection between the cable clamp and the tower crane can be achieved. Regarding the above-mentioned related technologies, the inventor believes that the adaptability of the cable clamp to tower cranes of different specifications needs to be improved. Utility Model Content

[0003] To improve the adaptability of cable fixing devices to tower cranes of different sizes, this application provides a tower crane cable insulation fixing device.

[0004] The technical solution for the tower crane cable insulation fixing device provided in this application is as follows: A tower crane cable insulation fixing device includes a mounting base installed on the tower body, a clamping body installed on the mounting base for arranging cables, and a locking member for connecting the mounting base and the clamping body. The mounting base includes a first locking plate and a second locking plate arranged opposite to each other, and a telescopic sliding structure for adjusting the distance between the first locking plate and the second locking plate. The first locking plate has a first locking hole on the side away from the telescopic sliding structure, penetrating its inner and outer surfaces, for arranging the locking member. The second locking plate has a second locking hole opposite to the first locking hole, penetrating its inner and outer surfaces, for arranging the locking member. The clamping body has a locking portion for locking the locking member and a third locking hole is provided in the locking portion.

[0005] By adopting the above technical solution, when fixing the cable to the tower crane, the operator first installs the cable onto the clamping body, and then installs the mounting base onto the tower body, so that the first locking plate and the second locking plate clamp the tower body. The locking element is then passed through the first locking hole, the second locking hole and the third locking hole in sequence to fix the mounting base to the clamping body, thereby fixing the cable to the tower crane. By adjusting the telescopic sliding structure, the distance between the first locking plate and the second locking plate can be adjusted, which helps to improve the adaptability of the cable fixing device to tower cranes of different sizes.

[0006] Optionally, there are two first locking holes arranged symmetrically on the first locking plate, and each of the two first locking holes is provided with a locking element; there are two second locking holes arranged directly opposite each of the two first locking holes.

[0007] By adopting the above technical solution, two symmetrically arranged first locking holes are respectively equipped with locking components, and two second locking holes are directly opposite the first locking holes, making the connection between the mounting base and the clamping body more stable and helping to improve the overall stability of the fixing device.

[0008] Optionally, the clamping body is installed on the side of the second locking plate away from the first locking plate; the clamping body includes a first clamping block and a second clamping block slidably arranged on the first clamping block; the locking parts are symmetrically arranged on both sides of the first clamping block.

[0009] By adopting the above technical solution, the specific structure of the clamping body is disclosed. By using the first clamping block and the second clamping block that is slidably arranged on the first clamping block, the clamping space can be flexibly adjusted to adapt to cables of different sizes. The locking parts are symmetrically arranged on both sides of the first clamping block, which can make the locking more stable and enhance the fixing effect on the cable.

[0010] Optionally, the first clamping block is provided with a U-shaped groove on the side facing the second locking plate for sliding arrangement of the cable, and the U-shaped groove is provided with guide grooves on both side walls along the axial direction parallel to the third locking hole for sliding arrangement of the second clamping block; the second clamping block has a sliding protrusion that cooperates with the guide groove.

[0011] By adopting the above technical solution, the U-shaped groove provides space for the cable to slide and arrange, which facilitates the installation and adjustment of the cable; the cooperation between the guide groove and the sliding protrusion enables the second clamping block to slide stably on the first clamping block, which helps to ensure that the cable is accurately and securely clamped.

[0012] Optionally, the second clamping block has an arcuate groove opposite the U-shaped groove for accommodating the cable.

[0013] By adopting the above technical solution, an arc-shaped groove that matches the U-shaped groove is set in the second clamping block, which makes the cable more stably attached and arranged in the U-shaped groove, helps to reduce the risk of the cable swaying left and right, and improves the reliability of the cable fixing.

[0014] Optionally, the mounting base further includes a first side plate connected to the upper edge of the first locking plate and extending toward the side closer to the second locking plate, and a second side plate connected to the upper edge of the second locking plate and extending toward the side closer to the first locking plate; the first side plate and the second side plate are slidably arranged relative to each other, and the telescopic sliding structure is arranged on the first side plate and the second side plate.

[0015] By adopting the above technical solution, a first side plate and a second side plate that slide relative to each other are provided on the upper edge of the first locking plate and the second locking plate, and a telescopic sliding structure is provided between the first side plate and the second side plate. This allows for a more stable adjustment of the distance between the first locking plate and the second locking plate, which helps to improve the compatibility of the mounting base with the fixing of tower cranes of different sizes.

[0016] Optionally, the telescopic sliding structure includes a first slide groove formed on the surface of the first side plate for sliding arrangement of the second side plate, and a first slider arranged on the second side plate and sliding in cooperation with the first slide groove; the bottom of the first slider is provided with an arrangement hole and a ball spring plunger is installed in the arrangement hole, and the bottom of the first slide groove has a snap-fit ​​hole for the plunger ball of the ball spring plunger to snap into.

[0017] By adopting the above technical solution, the sliding of the second side plate relative to the first side plate can be realized by the cooperation of the first slider and the first sliding groove, which facilitates the adjustment of the distance between the first locking plate and the second locking plate; the plunger ball of the ball spring plunger engages with the locking hole, which can effectively position the ball when it is adjusted to the appropriate position, ensuring the stability and accuracy of the distance adjustment.

[0018] Optionally, the number of snap-fit ​​holes is not less than four and they are evenly spaced along the length of the first slide groove.

[0019] By adopting the above technical solution, the snap-fit ​​holes, which are not less than four and evenly spaced along the length of the first slide groove, can stably fix the first locking plate and the second locking plate in multiple positions, realize multi-level adjustment of the spacing, and help to further improve the installation adaptability to tower cranes of different sizes.

[0020] Optionally, the telescopic sliding structure includes a plug groove formed at the end of the first side plate and extending along the length direction, a plug part arranged on the first side plate and cooperating with the plug groove, and a positioning bolt installed on the first side plate for pressing the plug part against the inner wall of the plug groove; a positioning hole is formed at the top of the first side plate, communicating with the plug groove and for installing the positioning bolt; the plug part has an abutting surface on the side away from the positioning hole that abuts against the inner wall of the plug groove.

[0021] By adopting the above technical solution, the telescopic sliding structure uses a combination of a plug-in groove, a plug-in part, and positioning bolts. The positioning bolts press the plug-in part against the inner wall of the plug-in groove, which can easily adjust the distance between the first locking plate and the second locking plate. At the same time, the abutting surface abuts against the inner wall of the plug-in groove, which can ensure the stability of the structure of the mounting base after the distance is adjusted.

[0022] Optionally, the second side plate has a damping layer on the abutment surface.

[0023] By adopting the above technical solution, setting a damping layer on the contact surface can increase the friction between the second side plate and the inner wall of the insertion groove, making the positioning of the telescopic sliding structure more stable after adjusting the spacing, thereby ensuring that the installation base and tower crane are more firmly fixed.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. A tower crane cable insulation fixing device, comprising a mounting base, a clamping body, and a locking component; when fixing the cable to the tower crane, the operator first installs the cable onto the clamping body, then installs the mounting base onto the tower body, so that a first locking plate and a second locking plate clamp the tower body, and the locking component passes through a first locking hole, a second locking hole, and a third locking hole in sequence to fix the mounting base to the clamping body, thereby fixing the cable to the tower crane; by adjusting the telescopic sliding structure, the distance between the first locking plate and the second locking plate can be adjusted, which helps to improve the adaptability of the cable fixing device to tower cranes of different sizes; 2. By cooperating with the first slider and the first groove, and by engaging the ball head of the ball spring plunger with the locking hole, the second side plate can slide relative to the first side plate. This helps to adjust the distance between the first locking plate and the second locking plate, so that the second side plate can be effectively positioned when adjusted to the appropriate position, thereby improving the stability and accuracy of the distance adjustment between the first locking plate and the second locking plate. 3. By using the combination of the insertion slot, insertion part and positioning bolt, the positioning bolt presses the insertion part against the inner wall of the insertion slot, which helps to adjust the distance between the first locking plate and the second locking plate. At the same time, the abutting surface abuts against the inner wall of the insertion slot, which improves the stability of the mounting base structure after the distance is adjusted.
