Abstract
Description
Technical Field
[0001] The utility model relates to a sling, in particular to a sling used for sand blasting of structural parts, and belongs to the technical field of design and manufacturing of anti-corrosion process equipment. Background Art
[0002] At present, before the anti-corrosion of structural parts, the sandblasting needs to support or lift the structural parts to a certain height, and then the surface of the structural parts can be cleaned, impurities and dirt on the surface can be removed, and the surface can be roughened to improve the adhesion of the anti-corrosion coating and extend the anti-corrosion time. When supporting or lifting structural parts, the sling is the main tool used. Most of the existing sandblasting slings use fixed support frames with fixed connection holes for support or lifting. When the lifting point of the sandblasting workpiece needs to be moved, especially when the lifting points of workpieces of different specifications are greatly different, the operator needs to remove the rope for lifting the workpiece from the sling before reinstalling it in the appropriate position. The construction operation is relatively troublesome, and the existing lifting round holes are also difficult to adapt to the lifting of all workpieces that need to be sandblasted. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a lifting device for sand blasting of structural parts which can be suitable for sand blasting of structural parts with different specifications and is convenient for construction and operation.
[0004] The technical solution adopted to solve the above technical problems is: a sling for sand blasting of structural parts, the sling comprises a hanger and an adjustable connecting structure, and the structural parts to be sand blasted are adjustably arranged on the hanger through various connecting points of the adjustable connecting structure.
[0005] Furthermore, the sling also includes at least two groups of connecting lifting ears, each connecting lifting ear is evenly distributed on the top surface of the hanger, and the hanger connected with the structural member is lifted or lowered by the connecting lifting ears with the cooperation of the external lifting equipment.
[0006] A preferred embodiment of the above scheme is that the hanger is a lifting truss welded from steel sections, the connecting lugs are arranged on the top surface of the lifting truss, and the adjustable connecting structure is movably connected to the lower part of the lifting truss.
[0007] Furthermore, the projection of the lifting truss in the horizontal plane is in a frame shape or a grate shape.
[0008] A preferred embodiment of the above scheme is that the adjustable connection structure comprises a plurality of groups of pulley hooks, and each group of pulley hooks is slidably arranged on the lower part of the lifting truss through the corresponding skeleton steel of the lifting truss.
[0009] Furthermore, each set of pulley-type hooks comprises a hook, a set of slides and four sets of pulleys. The hook is movably arranged on the slide, and the four sets of pulleys are movably arranged on the slide. The pulley-type hook is slidably arranged at the lower part of the lifting truss along the lower edge of the skeleton steel through the four sets of pulleys.
[0010] A preferred embodiment of the above scheme is that the adjustable connection structure comprises a plurality of groups of horizontally arranged sawtooth holes, and each group of horizontally arranged sawtooth holes is respectively and correspondingly arranged on the web of the corresponding skeleton steel.
[0011] The beneficial effect of the utility model is that the technical solution provided by the application is to set up a set of slings including a hanger and an adjustable connection structure, and then the structural parts that need to be sanded are arranged on the hanger in an adjustable manner through the various connection points of the adjustable connection structure. Since the connection between the frame and the structural parts in the sling of the application is realized through the adjustable connection structure, the connection points can be easily adjusted according to the different lifting points of the structural parts of different specifications, so that the sling of the application can be suitable for sanding structural parts of different specifications, and the adjustment construction operation during the connection is also very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a front view of the sling used for sand blasting of structural parts according to the utility model;
[0013] Figure 2 for Figure 1 Top view of the .
[0014] Marked in the figure: hanger 1, connecting ear 2, serrated hole 3. DETAILED DESCRIPTION
[0015] like Figure 1 , Figure 2 The utility model shows a sling for sand blasting of structural parts of different specifications, which is suitable for sand blasting of structural parts and convenient for construction operation. The sling comprises a hanger 1 and an adjustable connection structure, and the structural parts to be sand blasted are adjustably arranged on the hanger through the various connection points of the adjustable connection structure. The technical solution provided by the present application is to set up a set of slings including a hanger and an adjustable connection structure, and then the structural parts to be sand blasted are adjustably arranged on the hanger through the various connection points of the adjustable connection structure. Since the connection between the frame and the structural parts in the sling of the present application is realized through the adjustable connection structure, the connection points can be conveniently adjusted according to the different lifting points of structural parts of different specifications, so that the sling of the present application can be suitable for sand blasting of structural parts of different specifications, and the adjustment construction operation during the connection is also very convenient.
[0016] Correspondingly, in combination with the prior art, in order to facilitate the connection with external lifting equipment during lifting, the sling described in the present application also includes at least two groups of connecting lugs 2, each of which is evenly distributed on the top surface of the hanger 1. The hanger 1 connected with the structural member is lifted or lowered by the connecting lugs 2 with the cooperation of the external lifting equipment. Combined with the specifications of the structural member to be lifted and the conditions of the production site, in order to save costs as much as possible, the hanger 1 described in the present application is a lifting truss welded from steel sections, and the connecting lugs 2 are arranged on the top surface of the lifting truss, and the adjustable connection structure is movably connected to the lower part of the lifting truss. More specifically, the projection of the lifting truss in the horizontal plane is frame-shaped or grate-shaped.
[0017] As a key component improved in the present application, combined with production practice, the adjustable connection structure described in the present application can adopt at least the following two structural forms. One is that the adjustable connection structure includes multiple groups of pulley-type hooks, and each group of pulley-type hooks is slidably arranged on the lower part of the lifting truss through the corresponding skeleton steel of the lifting truss. At this time, each group of pulley-type hooks includes a hook, a group of slides and four groups of pulleys. The hooks are movably arranged on the slides, and the four groups of pulleys are movably arranged on the slides. The pulley-type hooks are slidably arranged on the lower part of the lifting truss along the lower edge of the skeleton steel through the four groups of pulleys. The other is that the adjustable connection structure includes multiple groups of horizontally arranged serrated holes 3, and each group of horizontally arranged serrated holes 3 is respectively and correspondingly arranged on the web of the corresponding skeleton steel.
[0018] In summary, the sling provided by the present application, whether it adopts a pulley-type hook structure or a sawtooth hole form, can be very convenient for sand blasting operators to adjust the lifting point and reduce the workload. When sand blasting, after the lifting rope of the structural member is fixed, the lifting rope can be moved freely within the range to select a more suitable lifting point, which is convenient for the operator to work and adds more adjustment positions.
