[0026] Embodiment 1

[0027] As Figure 1 and Figure 2 shown, a traveling block system applicable to a top drive integrated drilling system includes: a traveling block 100 and a plurality of lifting rings 200; the traveling block 100 includes: a load-bearing housing 101, at least two lower connecting ears 1011 are arranged at the lower part of the load-bearing housing 101, each lower connecting ear 1011 correspondingly connects a first end of a lifting ring 200, and a second end of each lifting ring 200 is connected to a swivel 1.

[0028] The principle is as follows: lower connecting ears 1011 are arranged at the lower part of the load-bearing housing 101 of the traveling block 100, the lifting rings 200 are connected through the lower connecting ears 1011, and the swivel 1 is directly connected through the lifting rings 200; correspondingly, a lifting lug for connecting the lifting ring 200 is also arranged on the swivel 1, so that there is no need to connect the swivel 1 through a drilling hook, the distance between the traveling block 100 and the swivel 1 is shortened, the drilling space of the derrick is saved, and the rotation and swing of the swivel 1 caused by the drilling hook can be avoided, improving the stability and the efficiency of tripping operations.

[0029] As Figures 1 to 3As shown, in this embodiment, the traveling block 100 further includes: a pulley 102, a pulley shaft 103, and a load-bearing side plate 104; the pulley shaft 103 is connected to the load-bearing housing 101, there are a plurality of pulleys 102, and the plurality of pulleys 102 are arranged in parallel and coaxially connected to the pulley shaft 103; there are a plurality of load-bearing side plates 104, and the plurality of load-bearing side plates 104 are respectively connected to the load-bearing housing 101 and the pulley shaft 103, and all the load-bearing side plates 104 are respectively arranged between the two outermost pulleys 102.

[0030] As Figure 2 shown, in an alternative embodiment, there are two load-bearing side plates 104, and the two load-bearing side plates 104 are symmetrically arranged. Specifically, the load-bearing side plate 104 is arranged between the outermost pulley 102 and the second outermost pulley 102, and a load-bearing side plate 104 is arranged between the outermost pulley 102 and the second outermost pulley 102 on both sides, so that the force on the pulley shaft 103 is uniform.

[0031] The principle is as follows: Taking the example of 5 pulleys 102 and 2 load-bearing side plates 104 arranged in parallel, if the load-bearing side plates 104 are arranged outside all the pulleys 102 and the load-bearing side plates 104 are connected to both ends of the pulley shaft 103, the two ends of the pulley shaft 103 are the main stress positions at this time. The distance between the two main stress positions is at least the width of 5 pulleys 102, which makes the distance between the two main stress positions longer, and the shaft bending moment on the pulley shaft 103 also increases accordingly, which has an adverse effect on the mechanical properties of the pulley shaft 103. And when all the load-bearing side plates 104 are respectively arranged between the two outermost pulleys 102, still taking 5 pulleys 102 and 2 load-bearing side plates 104 as an example, when the load-bearing side plates 104 are arranged between the outermost pulley 102 and the second outermost pulley 102, the distance between the two main stress positions on the pulley shaft 103 is reduced to the width of 3 pulleys 102, which makes the distance between the two main stress positions shorter, and the shaft bending moment on the pulley shaft 103 also decreases, thereby improving the mechanical properties of the pulley shaft 103.

[0032] As Figure 2 shown, in an alternative embodiment, one end of the pulley shaft 103 is fixedly connected to the load-bearing housing 101 through a cover plate 105. The load-bearing housing 101 is the main load-bearing member of the traveling block 100, and the pulley shaft 103 is fixed on the load-bearing housing 101 through the cover plate 105 to ensure firm connection.

[0033] In an alternative embodiment, a bearing is arranged inside each pulley 102, and all the bearings are coaxially connected to the pulley shaft 103 to make the rotation of the pulley 102 smooth.

[0034] As Figure 2 and Figure 3As shown, in an alternative embodiment, a cross beam 106 is provided on the upper part of the load-bearing housing 101. The cross beam 106 is connected to the load-bearing housing 101 through a cross beam pin 107. Further, a round hole is provided on the cross beam 106 for easy lifting, that is, the traveling block 100 and its auxiliary equipment can be integrally lifted through the round hole on the cross beam 106.

[0035] As Figure 2 and Figure 3 shown, in an alternative embodiment, a protective cover is provided outside the load-bearing housing 101. The protective cover is fixedly connected to the load-bearing housing 101 through a protective cover pin, and is used to protect the pulley 102 and prevent the wire rope from disengaging from the pulley groove of the pulley 102.

[0036] As Figure 1 and Figure 2 shown, in an alternative embodiment, the traveling block system applicable to the top drive integrated drilling system further includes a plurality of sling pins 300. The first end of each sling 200 is connected to the lower lugs 1011 through a sling pin 300, and the second end of each sling 200 is connected to the swivel 1 through a sling pin 300, that is, both the first end and the second end of the sling 200 are connected to the traveling block 100 and the swivel 1 through the sling pin 300.

[0037] As Figure 4 shown, specifically, a stop groove 301 is provided at one end of each sling pin 300.

[0038] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the traveling block system applicable to the top drive integrated drilling system further includes a plurality of stop blocks 400. Each stop block 400 is at least partially located in the stop groove 301, and the plurality of stop blocks 400 are respectively fixedly connected to the load-bearing housing 101 or the swivel 1. Further, pin holes 401 are spacedly provided on each stop block 400, and a stop pin passes through the pin holes 401 and is fixedly connected to the load-bearing housing 101 or the swivel 1. Preferably, at least two pin holes 401 are provided, and the two pin holes 401 are spacedly arranged.

[0039] The principle is that the stop block 400 functions to prevent the rotation of the sling pin 300. The stop block 400 is fixedly connected to the load-bearing housing 101 or the swivel 1 and interacts with the stop groove 301 on the sling pin 300. When the sling pin 300 is about to rotate due to force, its rotation will be blocked by the stop block 400 disposed in the stop groove 301. Through the stop block 400, the rotation and swing of the swivel 1 during operation are further avoided, improving the stability and working efficiency.

[0040] The traveling block system of the present utility model is applicable to the top drive integrated drilling system. The traveling block is directly connected to the swivel through the elevator link, shortening the distance between the traveling block and the swivel, improving the stability and production efficiency, and saving the drilling space of the derrick. By placing the support side plates between the pulleys, the load condition of the pulley shaft is effectively improved, and the mechanical properties are enhanced.

[0041] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, so that an article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the article or device including the said element. Words such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The orientation or positional relationship indicated by "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
