Description

Technical Field

[0001] This utility model relates to a roller assembly structure, and more particularly to a novel roller assembly structure for a construction hoist, which belongs to the field of construction lifting and transportation machinery technology. Background Technology

[0002] Rollers are key components of construction hoists that guide the cage and drive unit as they move up and down along the guide rail frame riser. Due to manufacturing errors in the steel structures such as the cage, drive unit, and guide rail frame sections, the precision cannot be guaranteed to be 100%. Therefore, the rollers have an eccentric adjustment function to adjust the gap between the rollers and the guide rail frame riser during use, thereby ensuring that the cage can move smoothly and stably during operation.

[0003] The existing roller structure has the following main defects: 1) The eccentric shaft is cumbersome to manufacture. Since the eccentric shaft needs to be adjusted eccentrically, and the wrench of this type of eccentric shaft structure is located in the middle, the diameter of the raw material is required to meet the processing conditions (the largest diameter is required). At the same time, the precision machining process is relatively complex and cumbersome; 2) The mounting lugs of the rollers need to be designed and manufactured with countersunk holes, which makes the overall processing and manufacturing process of the cage and drive frame complex; 3) The roller assembly has a cantilever structure with single-sided force, which is slightly unstable and can easily cause the roller mounting nuts to loosen; 4) Since the cantilever end is exposed, special sealing measures are required, such as the installation of sealing rings and end caps, which is slightly cumbersome to install. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a new type of construction hoist roller assembly structure that is reasonably designed, stable and reliable, easy and simple to install, and suitable for mass production and high-precision manufacturing.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: The new construction hoist roller assembly structure includes a roller assembly, a fastening standard part and two mounting plates. The feature is that it also includes a bolt, a support bushing, a spacer and two adjusting eccentric bushings. One end of the bolt is threaded to the fastening standard part. The bolt is hinged to the round holes of the two adjusting eccentric bushings. The adjusting eccentric bushings and spacers are hinged to the round holes of the bolt. The adjusting eccentric bushings are hinged to the two mounting plates by round holes. The roller assembly is sleeved on the support bushing.

[0006] Preferably, a play clearance of the roller assembly is provided between the support bushing and the spacer sleeve of this utility model.

[0007] Preferably, the mounting plate of this utility model is equipped with an adjusting eccentric bushing, which has an adjusting function, and the adjusting eccentric bushings on the two mounting plates are identical.

[0008] Preferably, the bolts and the two adjusting eccentric bushings of this invention are all clearance-fitted and movably connected.

[0009] Compared with the prior art, this utility model has the following advantages and effects: (1) The overall structure is reasonably designed, stable and reliable, and uses high-strength standard bolts, making installation more convenient and simple; (2) Since the adjustment eccentric bushings on both sides are exactly the same, it is easier to process in batches and the accuracy is easier to ensure. At the same time, during installation, it is only necessary to directly position on both sides, which is more convenient and simpler than the installation of long eccentric shafts; (3) The adjustment eccentric bushing is more suitable for batch and high-precision manufacturing. The overall installation method is a two-end support structure, which ensures the stability of the roller structure. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0015] Example.

[0016] See Figures 1 to 3 The novel construction hoist roller assembly structure in this embodiment includes bolts 7-1, support bushings 3-1, spacers 6-1, roller assembly 9-1, fastening standard parts 1-1, two adjusting eccentric bushings 2-1, and two mounting plates 8-1.

[0017] In this embodiment, one end of bolt 7-1 is threadedly fixed to fastening standard part 1-1; bolt 7-1 is hinged to the round holes of two adjusting eccentric bushings 2-1 with clearance fit and movable connection.

[0018] In this embodiment, the eccentric bushing 2-1 is hinged to the round holes of the mounting plates 8-1 on both sides, with clearance fit and movable connection.

[0019] In this embodiment, the eccentric bushing 2-1, spacer 6-1 and bolt 7-1 are hinged to the round hole, with clearance fit and movable connection.

[0020] In this embodiment, the roller assembly 9-1 and the support bushing 3-1 are fitted with a clearance and are movably connected. The roller assembly 9-1 includes roller 4-1, bearing 5-1, etc., and is regarded as a whole.

[0021] In this embodiment, the left and right movement clearance of the roller assembly is ensured between the support bushing 3-1 and the spacer 6-1.

[0022] In this embodiment, the fastening standard component 1-1 includes mating nuts, washers, or spring washers.

[0023] In this embodiment, the roller assembly structure has mounting plates 8-1 at both ends, and the installation method is a two-end support structure. The mounting holes of the two mounting plates 8-1 are highly concentric and of the same size. An adjusting eccentric bushing 2-1 is mounted on the mounting plate 8-1, and the adjusting eccentric bushing 2-1 has an adjustment function. The adjusting eccentric bushings 2-1 on the two mounting plates 8-1 are identical. (See [link to documentation]). Figure 2 The eccentric bushing 2-1 is equipped with a circular positioning area Y1 and a wrench adjustment area B1.

[0024] Roller assembly 9-1 is mounted on support bushing 3-1, and spacer 6-1 is mounted on the other end. A special wrench is used for adjustment (see [link]). Figure 3 Simultaneously adjust the eccentric bushings 2-1 on both sides.

[0025] This embodiment of the novel roller structure eliminates the complex manufacturing process of the long eccentric shaft, replacing it directly with a high-strength standard bolt 7-1, making installation more convenient and simpler. The adjustment function is achieved by replacing the original longer eccentric shaft with a shorter adjusting eccentric bushing 2-1. Since the adjusting eccentric bushings on both sides are identical, mass production is easier, and precision is more easily guaranteed. Furthermore, installation only requires direct positioning on both sides, making it much simpler and more convenient than installing a long eccentric shaft. The adjusting eccentric bushing 2-1 of this roller structure is more suitable for mass production and high-precision manufacturing. The overall installation method uses a two-end support structure, ensuring the stability of the roller structure.

[0026] Based on the above description, those skilled in the art are already able to implement it.

[0027] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
