One wrench head is clamped at the wrench groove 18, and the other wrench is used to tighten the connecting steel wire rope nut 4 or the main steel wire rope nut 6, so as to lock the connecting steel wire rope nut 4 and the main steel wire rope nut 6.

[0039] The function of this groove: wrench, when locking 4, 5 or 5, 6, the groove position uses a dead wrench or an open wrench

[0040] The length of the main steel wire rope joint 7 and the connecting steel wire rope joint 3 placed in the connecting sleeve 5 is greater than 20 mm.

[0041] The main steel wire rope preloading end 9 and the connecting steel wire rope connecting end 1 are threaded rods, the main steel wire rope preloading end 9 passes through the first connecting hole 14 on the first side vertical pulley 15 and is screwed with a steel wire rope first locking nut 16.

[0042] The second side vertical pulley 11 is provided with a second connecting hole corresponding to the connecting steel wire rope connecting end 1 and the main steel wire rope joint 7, the connecting steel wire rope connecting end 1 or the main steel wire rope joint 7 passes through the second connecting hole and is screwed with a steel wire rope second locking nut 17.

[0043] The number of the second connecting holes is multiple, which are arranged vertically.

[0044] The number of the second connecting holes is two, one is an upper connecting hole 12 of the second connecting hole, and the other is a lower connecting hole 10 of the second connecting hole.

[0045] The lower end of the second connecting hole is provided with an extension sleeve 13, the connecting steel wire rope connecting end 1 or the main steel wire rope joint 7 is sequentially threaded through the second connecting hole, the extension sleeve 13 and is screwed with a steel wire rope second locking nut 17; the upper end of the extension sleeve 13 abuts against the periphery of the second connecting hole, and the upper end of the second locking nut 17 abuts against the lower end of the extension sleeve 13. The extension sleeve 13 is provided, which is equivalent to reducing the effective working length of the steel wire rope, and is suitable for the minimum width installation of the machine.

[0046] The utility model is suitable for the adjustment of the length of the steel wire rope when the double-column series gantry lifting machine needs different heights or widths.

[0047] The key of the steel wire rope length adjustment structure is that the length of the steel wire rope group (the main steel wire rope 8 + the connecting steel wire rope 2) is designed according to the maximum height H and the maximum width W when installation, and is used as the standard installation position of the machine.

[0048] When the second height H1 of the machine is reached, the connecting steel wire rope 2 and the connecting sleeve 5 are removed, so that the height of the machine is reduced, and the length of the steel wire rope is shortened.

[0049] When the third height H2 (the lowest position) of the machine is reached, the connecting steel wire rope 2 and the connecting sleeve 5 are removed, and the second steel wire rope lifting point (that is, the lower connecting hole 10 of the second connecting hole) of the increased pulley part is used, so that the length of the steel wire rope is deepened into the pulley part, and the purpose that the steel wire rope is not replaced and can be continuously used when the height of the machine is continuously reduced is achieved.

[0050] When the minimum width W1 of the machine is used, the extension sleeve 13 mode can be used in combination with the standard installation position or the low position H1.

[0051] The assembly process of the steel wire rope length adjustment structure is as follows (see Figure 1 ):

[0052] (1) the steel wire rope is cut according to the length required by the drawing after pre-stretching, and the steel wire rope is pressed according to the steel wire rope pressing requirement.

[0053] (2) the main steel wire rope nut 6 and the connecting sleeve 5 are installed in the main steel wire rope joint 7, the joint is screwed in with a length greater than 20mm, and the main steel wire rope nut 6 is locked.

[0054] (3) the connecting steel wire rope nut 4 is installed on the connecting steel wire rope joint 3, then the connecting steel wire rope joint 3 is screwed into the connecting sleeve 5, the screwing length is required to be greater than 20mm, and the connecting steel wire rope nut 4 is locked.

[0055] (4) the main steel wire rope preloading end 9 is preloaded to the first side column pulley 15 according to the standard installation position (see Figure 5 ).

[0056] The following steps need to be carried out at the customer's place, and there are five installation modes:

[0057] The first installation method: when installed in the standard position, the connecting steel wire connecting end 1 is connected to the standard position (i.e., the connecting hole 12 above the second connecting hole) on the second side column pulley 11 (see Figure 6 ).

[0058] The second installation method: when installed in the low position H1, the connecting steel wire 2 and the connecting sleeve 5 are disassembled (equivalent to reducing the overall length of the steel wire), and the main steel wire joint 7 is connected to the standard position (i.e., the connecting hole 12 above the second connecting hole) on the second side column pulley 11 (see Figure 7 ).

[0059] The third installation method: when installed in the low position H2 (the lowest position), the connecting steel wire 2 and the connecting sleeve 5 are disassembled, and the main steel wire pre-installed end 9 is connected to the second lifting point position (i.e., the connecting hole 10 below the second connecting hole) on the second side column pulley 11 (see Figure 8 ).

[0060] When installed in the minimum width W1, the lengthening sleeve 13 method needs to be used, which can be used in combination with the standard position and the low position H1. Due to structural reasons, the low position H2 cannot be combined with the lengthening sleeve 13 method.

[0061] The fourth installation method: when installed in the standard position and the minimum width W1, the connection method of the connecting steel wire connecting end 1 is shown in Figure 9 .

[0062] The fifth installation method: when installed in the low position H1 and the minimum width W1, the connection method of the main steel wire joint 7 is shown in Figure 10 .

[0063] As shown in Figure 11 , one side column is the main column, and the other side column is the auxiliary column. The minimum width W1 refers to the minimum width between the main column and the auxiliary column. The minimum width W1 is set to limit the size requirements of the lifting machine installation site, while meeting the vehicle width requirements. If the width between the main column and the auxiliary column is less than the minimum width W1, it cannot meet the vehicle width requirements.

[0064] Whether it is high or low installation or minimum width, it is completed by adjusting the overall length of the steel wire, and the lengthening sleeve 13 is additionally set, rather than multiple lifting point positions. The reasons are as follows:

[0065] In theory, multiple lifting point positions can be set, but in actual use, generally only two lifting points are set, and at most three lifting points are set, which is to reduce the installation difficulty at the user's place, Figure 5 which is generally pre-installed in the factory, Figure 6 , Figure 7 , Figure 8 ,Figure 9 is installed at the user, at this time the cylinder, chain and other components in the trolley are installed, the space for installing the steel wire rope is small. Figure 9 The lower end position of the lengthened sleeve 13 needs to increase a lifting point, which is basically at the middle position of the trolley, and it is more difficult to pass the steel wire rope joint into the lifting point. In addition, when the second lifting point position is used, the steel wire rope needs to pass through the newly added lifting point, which also increases the installation difficulty at the user.
