[0034] See also Figures 1 to 2 , a suspension wire pulley device 100 provided in one embodiment of the present application includes a pulley seat 1, a first wheel group 3 and a cable support 5. Wherein:

[0035] The pulley seat 1 is provided with a receiving groove 1a, the receiving groove 1a has a notch, and the receiving groove 1a passes through both sides of the pulley seat 1 along the first direction, the first wheel group 3 is arranged on the side where the notch of the receiving groove 1a is located, the first wheel group 3 and the groove wall of the receiving groove 1a together form a guide rail channel 1b, the guide rail channel 1b is used for the guide rail to pass through the pulley seat 1 along the first direction, and the first wheel shaft 3 is used for rolling cooperation with the guide rail. The cable bracket 5 is arranged on the side of the pulley seat 1 away from the opening of the receiving groove 1a, and the cable bracket 5 and the pulley seat 1 together form a cable groove 5a, and the cable groove 5a is used for the cable to pass through.

[0036] In the above-mentioned suspension wire pulley device 100, since the first wheel group 3 is arranged on the side where the notch of the receiving groove 1a is located, and the first wheel group 3 and the groove wall of the receiving groove 1a together form a guide rail channel 1b for the guide rail to pass through the pulley seat 1 along the first direction, when the suspension wire pulley device 100 is installed on the guide rail, the first wheel group 3 is located on the side of the guide rail close to the notch of the receiving groove 1a, playing the role of supporting the suspension wire pulley device 100. Since the first wheel group 3 can roll with the guide rail, when the overhead crane drives the suspension wire pulley device 100, the first wheel group 3 can roll relative to the guide rail, and the suspension wire pulley device 100 can move relative to the guide rail, so that the cable support 5 can drive the cable to move under the drive of the pulley seat 1, so as to ensure that the cable can move with the overhead crane and the cable will not be broken. Among them, since the first wheel group 3 is arranged on the side of the guide rail close to the notch of the receiving groove 1a, the damage of the first wheel group can be observed through the notch of the receiving groove 1a. Therefore, the suspension wire pulley device 100 can conveniently observe the degree of damage to the wheel group structure, which is conducive to quickly performing maintenance intervention on the wheel group structure, ensuring the reliability of the suspension wire pulley device 100 and reducing the risk of the cable being broken. In addition, compared with the suspension wire pulley device 100 in which the wheel group structure is embedded in the guide rail, the suspension wire pulley device 100 also has the advantages of simple structure and convenient disassembly and assembly.

[0037] In one embodiment, Figure 1 and Figure 2As shown, the first pulley group 3 includes a first pulley shaft 31 and a first pulley 32. The first pulley shaft 31 extends along a second direction, and the first direction and the second direction are arranged at an angle. Both ends of the first pulley shaft 31 are connected to the side walls of the accommodation groove 1a. The first pulley 32 is rotatably sleeved on the first pulley shaft 31, and the first pulley 32 is used for rolling cooperation with the guide rail. In this way, when the overhead crane drives the wire suspension pulley device 100, the first pulley 32 can roll relative to the guide rail, and the wire suspension pulley device 100 can move relative to the guide rail, so that the cable bracket 5 can drive the cable to move under the drive of the pulley seat 1, so as to ensure that the cable can follow the overhead crane and the cable will not be broken. Among them, since both the first pulley shaft 31 and the first pulley 32 of the first pulley group 3 are arranged on the side of the guide rail close to the notch of the accommodation groove 1a, it is possible to observe whether the first pulley shaft 31 is damaged and jammed or the first pulley 32 cannot rotate through the notch of the accommodation groove 1a. Therefore, the damage degree of the pulley group structure of the wire suspension pulley device 100 can be conveniently observed, which is beneficial to quickly perform operation and maintenance intervention on the pulley group structure, ensure the reliability of the wire suspension pulley device 100, and reduce the risk of the cable being broken.

[0038] Preferably, the second direction is perpendicular to the first direction. That is, the second direction is the same as the relative direction of the two side walls of the accommodation groove 1a.

[0039] Optionally, the number of the first pulley groups 3 can be selected according to needs. For example, it can be one, two, three or more.

[0040] Preferably, as Figure 1 and Figure 2 shown, the number of the first pulley groups 3 is two, and the two first pulley groups 3 are arranged at intervals along the first direction. In this way, the wire suspension pulley device 100 can be reliably slidably connected to the guide rail under the joint action of the two first pulley groups 3, which is beneficial to ensuring the reliability of the device.

[0041] Optionally, as Figure 1 and Figure 2 shown, limiting walls 33 are annularly arranged on the outer surfaces at both ends of the first pulley 32, and the two limiting walls 33 are used to limit the movement of the wire suspension pulley device along the second direction. In this way, the setting of the two limiting walls 33 can ensure that the wire suspension pulley device 100 stably moves relative to the guide rail along the first direction and also ensure the reliability of the rolling cooperation between the first pulley 32 and the guide rail.

[0042] In one embodiment, as Figure 1 and Figure 2As shown, the wire pulley device 100 includes a second wheel group 2 and a third wheel group 4, both of which are arranged in the receiving groove 1a, and both of which are arranged on the side of the first wheel group 3 close to the bottom of the receiving groove 1a, and the second wheel group 2 and the third wheel group 4 are used to roll with the guide rail on the opposite sides in the opposite direction of the two side walls of the receiving groove 1a. In this way, under the joint action of the first wheel group 3, the second wheel group 2 and the third wheel shaft 41, the wire pulley device 100 can reliably move relative to the guide rail along the first direction, ensuring the reliability of the device. In addition, since the second pulley 22 and the third pulley 42 both roll with the side wall of the guide rail, compared with the solution of using the side wall abutment to limit the moving direction of the wire pulley device 100, this design can effectively reduce the friction when the wire pulley device 100 moves relative to the guide rail, ensuring the stability of the movement of the wire pulley device 100. Since the accommodating groove 1a is a through groove with both ends penetrating, and the second wheel set 2 and the third wheel set 4 are respectively arranged on the opposite sides of the guide rail in the relative directions of the two side walls of the accommodating groove 1a, during use, the degree of damage of the second wheel set 2 and the third wheel set 4 can be conveniently observed through the two ends of the accommodating groove 1a and the notch of the accommodating groove 1a, which is beneficial to ensure the reliability of the device.

The second pulley 22 is rotatably sleeved on the second wheel shaft 21, and the second pulley 22 is used to roll with the guide rail. In this way, when the overhead crane drives the suspension wire pulley device 100, the second pulley 22 arranged in the receiving groove 1a can rotate relative to the second wheel shaft 21 to roll with the guide rail, thereby effectively increasing the stability of the movement process of the suspension wire pulley device 100.

In this way, the second wheel shaft 21 can be easily and quickly disassembled from the pulley seat 1, which is conducive to improving the assembly efficiency and maintenance efficiency of the suspension wire pulley device 100.

[0046] In other embodiments, the second axle 21 may also be connected to the base plate 12 by interference fit.

[0047] Optionally, the number of the second wheel sets 2 can be selected as needed, for example, it can be one, two, three or more.

[0048] Preferably, Figure 1 and Figure 2 As shown, there are two second wheel groups 2, and the two second wheel groups 2 are arranged at intervals along the first direction. In this way, the moving direction of the suspension wire pulley device 100 can be reliably defined, which is conducive to ensuring the reliability of the device.

The third pulley 42 is rotatably sleeved on the third wheel shaft 41, and the third pulley 42 is used to roll with the guide rail. In this way, when the overhead crane drives the suspension wire pulley device 100, the third pulley 42 arranged in the receiving groove 1a can rotate relative to the third wheel shaft 41 to roll with the guide rail, thereby effectively increasing the stability of the movement process of the suspension wire pulley device 100.

[0050] Optionally, the first direction is perpendicular to the second direction, and the extension direction of the third axle 41 is perpendicular to both the first direction and the second direction.

[0051] Optional, combined Figure 1 and Figure 2 As shown, the third wheel shaft 41 includes a third head and a third rod connected to each other, the third head is arranged on the side of the notch of the third pulley 42 close to the receiving groove 1a, and the end of the third rod away from the third head passes through the third pulley 42 and the groove bottom of the receiving groove 1a and is threadedly connected to the third nut.

The first side plate 11 and the second side plate 13 are arranged opposite to each other at intervals, and the bottom plate 12 is connected between the first side plate 11 and the second side plate 13. The first side plate 11, the second side plate 13 and the bottom plate 12 together form a receiving groove 1a. The first wheel set 3 is connected to both the first side plate 11 and the second side plate 13, and the cable bracket 5, the second wheel set 2 and the third wheel set 4 are all connected to the bottom plate 12. In this way, the first side plate 11, the second side plate 13 and the bottom plate 12 can enclose a "U"-shaped groove, and the guide rail can pass through the "U"-shaped groove, while the first wheel set 3, the second wheel set 2 and the third wheel set 4 can be reliably arranged in the "U"-shaped groove and rollingly cooperate with the guide rail, so that the wire hanging pulley device 100 can move relative to the guide rail under the drive of the overhead crane to drive the cable to move with the overhead crane, ensuring the reliability of the overall equipment.
