Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1-4 A medium-to-large-sized support roller hoisting equipment includes a hoisting unit 1, a hoisting platform 2, and a boom unit 3. The hoisting unit 1 is hoisted by a crane and is raised and lowered under the drive of the crane. At the same time, it can slide on the hoisting platform 2 to control the boom units 3 to move closer or further away from each other along the direction of the hoisting platform 2, thereby completing the clamping, lifting or lowering and unfolding of the two sides of the support roller.

[0028] The hoisting unit 1 includes a pair of symmetrically arranged clamping arms 11. The clamping arms 11 are bent and are hinged at the overlapping part of the clamping arms 11 by a connecting shaft 12. One end of the two clamping arms 11 is hinged to a connecting rod 14 by a pin 15, and the other end is connected to a pulling shaft 13 that slides with the hoisting platform 2. The pulling shaft 13 is used to control the hoisting unit 3 to slide on the hoisting platform 2.

[0029] The two clamping arms 11 are hinged by the lifting shaft 16, so that the clamping arms 11 and the connecting rod 14 form an intersecting quadrilateral structure. A lifting buckle 17 is also connected to the lifting shaft 16 for cooperation with the crane.

[0030] The lifting platform 2 includes a crossbeam 21, which is a hollow tube structure. The crossbeam 21 has first strip holes 22 on both sides, which are arranged laterally. The first strip holes 22 are used to insert and cooperate with the pulling shaft 13. The size of the first strip hole 22 corresponds to the size of the pulling shaft 13. When the crane controls the lifting unit 1 to lift, it can pull the clamp arm 11 to rotate the connecting shaft 12, and at the same time control the pulling shaft 13 to slide closer along the direction of the first strip hole 22.

[0031] A second strip hole 23 is also provided on both sides of the hoisting platform 2. The second strip hole 23 is used to cooperate with the boom unit 3 to form the assembly of the support roller.

[0032] The boom unit 3 includes a pair of sliding beams 31 slidably disposed within the crossbeam 21, and a pair of booms 33 sleeved on the outside of the crossbeam 21. The booms 33 are connected to the sliding beams 31 by a pin 34 passing through the second slot 23, so that the booms 33 and the sliding beams 31 form a whole. A through hole 32 is opened on the sliding beam 31 and corresponds to the first slot 22. The pull shaft 13 passes through the first slot 22 and the through hole 32. When the lifting unit 1 controls the pull shaft 13 to slide, it controls the sliding beams 31 to slide within the crossbeam 21, thereby driving the booms 33 to slide relative to each other. At this time, the pin 34 slides within the second slot 23.

[0033] In order to facilitate the control of the distance between the booms 33 and the size of the gripping support rollers, an adjustment hole 37 is also provided on the sliding beam 31. The adjustment hole 37 can cooperate with the booms 33 to adjust the position of the booms 33 on the sliding beam 31, thereby realizing the adjustment of the distance between the booms 33.

[0034] A baffle 35 is also connected to the end of the boom 33, and a support platform 36 is also connected to one side of the baffle 35. The support platform 36 can support the support roller, and the baffle 35 can limit the support roller. The baffle 35 at the end of the boom 33 and the support platform 36 form a clamping space. When the boom 33 approaches, the support platform 36 supports the bottom of the support roller, and the baffle 35 restricts its lateral displacement. When the boom 33 moves away, the support roller is released.

[0035] Specifically, the symmetrical clamping arms 11 of the hoisting unit 1 are hinged together by the connecting shaft 12 to form a cross quadrilateral structure. When the crane lifts, the hoisting shaft 16 drives the clamping arms 11 to rotate around the connecting shaft 12, while simultaneously pulling the shaft 13 to slide laterally along the first strip hole 22 of the hoisting platform 2.

[0036] The pull shaft 13 passes through the first strip hole 22 and is inserted into the through hole 32 of the sliding beam 31 of the boom unit 3. Its sliding directly drives the sliding beam 31 to move laterally inside the crossbeam 21.

[0037] The lateral movement of the sliding beam 31 is transmitted to the boom 33 through the pin 34. The pin 34 slides along the second strip hole 23 of the lifting platform 2, so that the boom 33 moves closer or further away from the sliding beam 31 in sync, that is, the support platform 36 moves closer or further away in sync, thereby realizing the adjustment of the clamping distance of the support roller.
