The front and rear ends of the first intermediate roller 35 are both fixed with right sprockets 36. Two right chains 37 are located on the inner sides of the two main side plates. Each right chain 37 is tensioned on all the right sprockets 36 on the corresponding side, and the right chain 37 is meshed with the corresponding right sprocket 36.

[0026] A left guide 40 is fixed to the corresponding part of the chain portion above the two left chains 27, and a right guide 50 is fixed to the corresponding part of the chain portion above the two right chains 37. The middle parts of the left guide 40 and the right guide 50 are both formed with wire rope threading holes 1.

[0027] Both ends of the left first rotating shaft 21, the left second rotating shaft 22, the left third rotating shaft 23, the left fourth rotating shaft 24, the right first rotating shaft 31, the right second rotating shaft 32, the right third rotating shaft 33 and the right fourth rotating shaft 34 are fixed on the front and rear main side panels.

[0028] Chain guide grooves extending left and right are formed on the upper parts of the relative walls of the two chain guide rails 11, and the left and right ends of the chain guide grooves extend downward in an arc shape, so that the running trajectories of the chain parts above the right chain 37 and the left chain 37 match the chain guide grooves, and the outer sides of the chain parts above the right chain 37 and the left chain 37 are inserted into the corresponding chain guide grooves. At the same time, relatively extended extension strips are formed on the upper parts of the relative walls of the two chain guide rails 11, and a downwardly extending raised strip 6 is formed on the bottom surface of the extended strip, which is inserted into the upper part between the two corresponding chain plates of the chain part above the right chain 37 or the left chain 37 to realize limited guiding.

The guide sprocket 2 realizes the tensioning effect on the left chain 27 or the right chain 37.

[0030] Furthermore, the inner ends of the corresponding pin shafts of the chain parts above the two left chains 27 or the right chains 37 are fixed with vertical plates of the bent connecting pieces 3, and the front and rear bottom surfaces of the left guide 40 and the right guide 50 are fixed on the top surfaces of the upper horizontal bent parts of the corresponding multiple bent connecting pieces 3.

The middle horizontal plate 51 is in the through groove, and the edges of the middle horizontal plate 51 are inserted into the corresponding inner grooves and cover the through groove. A wire rope threading hole 1 is formed in the middle of the middle horizontal plate 51.

[0032] The front of the left part, the front of the right part, the rear of the left part and the rear of the right part of the bottom surface of the middle horizontal plate 51 are all fixed with connecting frames 53, and the two ends of the middle rotating shaft of the wire rope clamping wheel 54 are fixed on the corresponding two connecting frames 53. The middle part of the wire rope clamping wheel 54 is formed with an annular groove. The wire rope 100 is inserted into the wire rope threading through hole 1 and is located between the annular grooves of the corresponding four wire rope clamping wheels 54. The four wire rope clamping wheels 54 can guide the wire rope 100 and reduce wear.

[0033] A plurality of baffles 5 are installed on the chain parts above the left chain 27 and the right chain 37 at both sides of the left guide member 40 and the right guide member 50, and bent connecting pieces 3 are fixed to the bottom surfaces of the front and rear ends of the baffles 5, and the vertical parts of the bent connecting pieces 3 are fixed to the corresponding pin shafts;

[0034] The left side wall and the right side wall of the baffle 5 are parallel oblique side walls, and the oblique side walls of two adjacent baffles 5 are close to each other and parallel to each other; the oblique side walls make the blocking effect between the baffles 5 better, and the baffle 5 is a transparent plate.

[0035] The left guide member 40 , the right guide member 50 , the middle limit connecting plate 12 , the two side limit connecting plates 13 and all the baffles 5 above cover the upper part between the two main side plates of the frame 10 .

[0036] When the baffle plate 5 moves, it will approach or lean against the outer wall surface of the corresponding first intermediate roller 35 or the intermediate roller 25 , thereby supporting the baffle plate 5 .

[0037] In this embodiment, the bottom of the left and right parts of the frame 10 are fixed to the lower mounting positions on the left and right sides of the central through slot of the lifting seat, covering the central through slot, and the two vertically extending steel wire ropes of the winch are inserted into the corresponding steel wire rope threading through holes 1 and are located between the corresponding annular grooves of the four steel wire rope clamping wheels 54. The four steel wire rope clamping wheels 54 guide the steel wire rope 100 to reduce friction, prevent the steel wire rope 100 from contacting the inner side wall of the steel wire rope threading through hole 1 and generating friction and wear, so that the steel wire rope 100 is damaged or the side wall of the steel wire rope threading through hole 1 is damaged, affecting its use.

[0038] When in use, as the winch runs, when the wire rope is lowered or restored to lift, it will move left and right with the drum. At this time, it will drive the left guide member 40 or the right guide member 50 to move left or right. When moving, it will drive the corresponding left chain 27 and right chain 37 to run, so as to realize the movement of the left transmission mechanism 20 and the right transmission mechanism 30, ensuring that the middle through groove is covered at all times, and at the same time, ensuring the normal pulling and lowering of the wire rope, and the use effect is very good.

[0039] Finally, the above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
