Abstract

The utility model discloses a membrane wall hook, comprising a hook body (1). The membrane wall hook is characterized in that a clamping opening (2) is arranged on the hook body; an arc notch (3) is arranged on the clamping surface at the left lower side of the clamping opening (2); the right clamping surface of the clamping opening (2) is composed of a hook sleeve (4) which is axially and horizontally arranged; a hook screw (5) is connected with the hook sleeve (4) through a thread; the top end of the hook screw (5) is movably connected with a hook sliding block (6) capable of freely rotating along the axial direction of the hook screw (5); and a concave arc opening (7) matched with the arc notch (3) to clamp a side tube of a membrane wall tube screen is arranged on the hook sliding block (6). The membrane wall hook is mainly used for carrying out lifting, turnover, bending discharging and the like on the membrane wall tube screen, and has the advantages of being convenient to use, rapid, safe and the like.

Description

A kind of membrane wall suspension hook

Technical field

The utility model belongs to mechanical engineering, is used instrument in the production of special equipment manufacture and the installation process.

Background technology

The producer of at present special equipment manufacturing production boiler diaphragm type wall increases gradually, but for designing and developing seldom of membrane wall lifting tool, also be useful on the suspension hook that the lifting membrane wall is used on the market, but the more complicated price of structure is also very expensive, be difficult to apply in market, in the membrane wall actual production, the traditional lifting tool of the many employings of the producer, namely adopt nylon flat sling lifting membrane wall, this suspender belt is inconvenient operation but also exist very large potential safety hazard not only, because most of membrane panels both sides all are welded with band steel, in the lifting process these band steels can be as cutter cutting and decrease suspender belt and form potential safety hazard slowly.Tube panel on many membrane wall products is to need row curved in addition, and at this moment tube panel will erect sometimes, and suspender belt is difficult to accomplish this point, and large especially to the wearing and tearing of suspender belt, and causing suspender belt often to change has increased productive costs.

Summary of the invention

The utility model provides a kind of convenient, fast, safe membrane wall suspension hook that lifts by crane for fear of the weak point that prior art exists, be used for membrane wall lifting, stand up, arrange the operations such as curved.

The utility model technical solution problem adopts following scheme:

A kind of membrane wall suspension hook, comprise hook, its constructional feature is, described hook is provided with clamp port, the lower-left side clamping face of described clamp port is provided with an arc-shaped notch, the right side clamping face of described clamp port is made of an axial horizontally disposed suspension hook sleeve, be provided with the suspension hook screw mandrel that is threaded in the described suspension hook sleeve, the top of described suspension hook screw mandrel is connected with can be along the suspension hook screw axis to the suspension hook slide block that rotates freely, and described suspension hook slide block is provided with the concave arc mouth that matches to clamp membrane panel side pipe with arc-shaped notch.

The utility model constructional feature also is:

Described suspension hook screw mandrel is provided with threaded portion and sliding part, and described threaded portion is threaded with the internal thread part of suspension hook sleeve, described sliding part and suspension hook sleeve lining bearing fit.

The top of described suspension hook screw mandrel is connected by bearing and the rotation of suspension hook slide block.

Adopt interference fit between described suspension hook screw mandrel and bearing, bearing and suspension hook slide block.

Described suspension hook slide block and suspension hook sleeve adopt free-running fit.

The tail end of described suspension hook screw mandrel is provided with rotating handles.

Compared with the prior art, the utility model beneficial effect is embodied in:

The utility model be mainly used in the large-scale tube panel in the film-type wall boiler product lifting,, stand up, arrange the operations such as curved, have the advantages such as easy to use, quick, safe.

Number in the figure: 1. hook, 2. clamp port, 3. arc-shaped notch, 4. suspension hook sleeve, 41. internal thread parts, 5. suspension hook screw mandrel, 6. suspension hook slide block, 7. concave arc mouth, 8. bearing, 9. rotating handles, 10 membrane panels.

Technical solutions of the utility model are described further by the specific embodiment below in conjunction with accompanying drawing.

The specific embodiment

Shown in Fig. 1-4, the membrane wall suspension hook, comprise hook 1, hook 1 is provided with clamp port 2, the lower-left side clamping face of clamp port 2 is provided with an arc-shaped notch 3, and the right side clamping face of clamp port 2 is made of an axial horizontally disposed suspension hook sleeve 4, is provided with the suspension hook screw mandrel 5 that is threaded in the suspension hook sleeve 4, the top of suspension hook screw mandrel 5 is connected with the suspension hook slide block 6 that can axially rotate freely along suspension hook screw mandrel 5, and tail end is provided with rotating handles 9.Suspension hook slide block 6 is provided with the concave arc mouth 7 that matches to clamp membrane panel 10 side pipes with arc-shaped notch 3.

As shown in Figure 2, suspension hook screw mandrel 5 is provided with threaded portion 51 and sliding part 52, and threaded portion 51 is threaded with the internal thread part 41 of suspension hook sleeve 4, sliding part 52 and suspension hook sleeve lining bearing fit.

During implementation, the top of suspension hook screw mandrel 5 can be connected by bearing 8 and 6 rotations of suspension hook slide block.Suspension hook screw mandrel 5 and bearing 8, bearing 8 and 6 of suspension hook slide blocks adopt interference fit.Suspension hook slide block 6 adopts free-running fit with suspension hook sleeve 4.So in use the suspension hook slide block not only is difficult for loosening falling down, and very good rotation; Suspension hook slide block arc-shaped notch 3, suspension hook internal thread of sleeve 41, suspension hook screw mandrel 5 are preferably done surface hardening, thereby make its more wear-resisting increasing the service life with the hardness that increases contact surface; Suspension hook sleeve 4 is determined according to the membrane wall pipe diameter with the fitted position of hook 1, can put into smoothly hook to guarantee tubing.

The finish size of each parts of the utility model is come fixed cun according to the weight of diameter, band steel specification and the membrane panel of membrane wall pipe, with the lifting of the membrane panel that is applied to different size and size,, stand up, arrange the operations such as curved.

The utility model membrane wall suspension hook in use should regularly add lubricating oil in suspension hook screw mandrel 5, the alerting ability that can not only increase operation can also prevent that it from getting rusty.As shown in Figure 5, the operator screws in suspension hook slide block 6 in the suspension hook sleeve 4 by rotating handles 9 first when using this suspension hook fully, the side of suspension hook clamp port 2 being aimed at membrane panel is again managed and is pushed, when tube panel side pipe is in the arc-shaped notch 3 of hook 1, rotating handles 9 is until the concave arc mouth 7 of suspension hook slide block 6 and the arc-shaped notch 3 of hook 1 encase tubing and screw, and suspension hook should be clipped in the position of tube panel mid point to guarantee the rear tube panel level of lifting.Erect or arrange when the needs tube panel and can use two suspension hooks to divide the left and right sides clamp to lift by crane simultaneously when curved.
