Description

Technical Field

[0001] The utility model belongs to the technical field of water tank grinding and hoisting, and in particular relates to a water tank grinding and hoisting device. Background Art

[0002] A water tank is a tank used to store water. In order to meet the water demand, water tanks are mostly large tanks. In addition, water tanks are mostly made of corrosion-resistant and oxidation-resistant materials such as stainless steel.

[0003] During the processing, different parts of the water tank are fixed by welding. Specifically, the water tank head, tank body, tank bottom, etc. are sealed and welded to form a completed water tank.

[0004] During the production process, in order to increase the corrosion resistance and oxidation resistance of the water tank, the water tank body parts need to be polished. For example, the tank body (the main body shape is a cylindrical structure) which accounts for a relatively large proportion of the water tank needs to be polished. Polishing increases its smoothness, which, on the one hand, increases its corrosion resistance and oxidation resistance, and on the other hand, after polishing, it is not easy to accumulate a large amount of dust.

[0005] Due to the large size and weight of the tank, it is necessary to hoist the tank onto the polishing table during polishing. However, it is difficult to hoist the heavy tank. At present, the more common method in the workshop is to use a steel wire rope to pass through the tank. However, during the hoisting process, the tank and the steel wire rope are prone to shaking, resulting in many scratches on the tank and even a gap at the filling port. This makes subsequent repairs more complicated.

[0006] The fundamental reason for the above method is that it is difficult to fix the tank body when hoisting the columnar structure, and the wire rope fixing method is difficult to fully keep the tank body in position. At the same time, the contact area between the wire rope and the tank body is small. After positioning, the tightening pressure of the wire rope on the tank body is too large, and it is very easy to be damaged. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a water tank grinding and hoisting device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A water tank grinding and hoisting device comprises a water tank body hoisting mechanism;

[0010] The water tank body hoisting mechanism comprises water tank mouth positioning components spaced apart on both sides, and the water tank body hoisting mechanism also comprises a water tank body internal support component assembled and connected between the water tank mouth positioning components;

[0020] Preferably, both ends of the horizontal long rod are respectively slidably connected to the inner diameter rod, and both ends of the horizontal long rod are respectively threadedly connected to a pair of positioning nuts positioned on both sides of the inner diameter rod.

[0021] Preferably, a plurality of tank mouth abutment components are fixedly assembled and connected to the outer side wall of the annular end plate, and the tank mouth abutment components are used to abut the tank body from the side.

[0022] Preferably, the tank mouth abutment component comprises a connecting screw fixedly connected to the annular end plate, and a abutment plate is slidably connected to the connecting screw;

[0026] The utility model has the following beneficial effects:

[0027] 1.

At the same time, the annular end plate is used to tighten the tank mouth position by abutting on both sides to further avoid loosening of the tank body during hoisting.

[0028] 2. The tank mouth abutment parts cooperate with the annular end plate to abut the tank mouth from the side, effectively avoiding relative shaking between the tank and the annular end plate, which causes the annular end plate and the tank mouth to stagger and disengage.

[0039] Example 1

[0040] like Figure 1-4 As shown, a water tank grinding and hoisting device includes a water tank body hoisting mechanism. Before grinding, the heavy and large tank body is hoisted and loaded onto the grinding table in an extremely stable manner through the water tank body hoisting mechanism, and the tank body is kept from being damaged during the hoisting process.

[0041] Specifically, the water tank body lifting mechanism includes water tank mouth positioning components spaced apart on both sides, through which the mouth positions on both sides of the tank body are positioned to prevent the tank body from shaking left and right on the horizontal line. Specifically, the water tank mouth positioning components include an annular end plate 11 that abuts against the mouth position of the water tank body (the annular end plate 11 is a steel plate, and its size corresponds to the mouth size of the tank body and can fully abut against the mouth position of the tank body), and an inner diameter rod 12 is fixedly connected inside the annular end plate 11 (the inner diameter rod 12 is located at the diameter position).

[0042] At the same time, in order to position the main body of the tank from the inside, the water tank body lifting mechanism also includes a water tank body internal support component assembled and connected between the water tank mouth positioning components.

[0043] Specifically, the internal support assembly includes a horizontally arranged center rod 32 (with a rectangular longitudinal cross-section, which is a cuboid steel rod), to which a horizontal long rod 31 is slidably connected (with a matching long hole provided on the center rod 32), and both ends of the horizontal long rod 31 are respectively assembled on the inner diameter rod 12.

[0044] The specific method is as follows: both ends of the horizontal long rod 31 are respectively slidably connected to the inner diameter rod 12 , and both ends of the horizontal long rod 31 are respectively threadedly connected to a pair of positioning nuts positioned on both sides of the inner diameter rod 12 .

[0045] In this way, when positioning is achieved, the distance between the annular end plates 11 on both sides is adjusted (the inner diameter rod 12 corresponds to the tank body and has a sufficient length), which is convenient for flexible adjustment according to the size of the tank body. The method is: after loosening the positioning nut, push the annular end plate 11 inward until the annular end plate 11 contacts the mouth of the tank body.

[0046] The above-mentioned center rod 32 (the center rod 32 is a rectangular parallelepiped) is fixedly assembled and connected with a plurality of abutment components that abut against the inner wall of the water tank body (specifically: the top, bottom, front side wall and rear side wall of the center rod 32 are respectively assembled and connected with abutment components arranged at intervals on both sides), and the abutment components include abutment plates 43; the abutment plates 43 are detachably and fixedly assembled with an adjusting screw 42, and the center rod 32 is fixedly connected with an adjusting screw tube 41 (the adjusting screw tube 41 has a threaded cavity) which is threadedly connected to the adjusting screw 42.

[0047] During the operation, the operator places the center rod 32-butt plate 43 assembly into the center of the tank body, and rotates the butt plates 43 until each butt plate 43 butts against the inner wall of the tank body. Under the butt of the butt plates 43 at the upper, lower, front and rear positions, the tank body is supported from the inside (corresponding to the water tank, its thickness is often thin, if it is not supported from the inside, it is easy to deform due to pressure during hoisting).

[0048] After supporting the interior of the tank body in the above manner, the operator then slides the horizontal long rod 31 through the center rod 32, and then installs the annular end plate 11 in the above manner until the annular end plate 11 abuts against the mouth of the tank body (before installing the annular end plate 11, pre-adjust the length of the two ends of the horizontal long rod 31 extending out of the tank mouth, and then, since there are several locking screws 311 threadedly connected to the center rod 32 for locking the horizontal long rod 31, the locking screws 311 are tightened to keep the horizontal long rod 31 fixed).

[0049] During operation, in order to increase the friction during the collision, according to the existing method of increasing friction, a plurality of friction protrusions 431 are integrally formed on the above-mentioned abutment plate 43 (the abutment plate 43 is preferably made of a thickened rubber plate).

[0050] Furthermore, in order to achieve replacement of the abutment plate 43, the following method is adopted:

[0051] A mounting sleeve 432 is fixedly connected to the inner wall of the abutment plate 43, and the mounting sleeve 432 is sleeved on the outer end of the adjusting screw 42. A fastening bolt fastened to the adjusting screw 42 is threadedly connected to the mounting sleeve 432 (a matching through hole is provided on the adjusting screw 42, and the fastening bolt passes through the adjusting screw 42 and the mounting sleeve and is fastened with a nut).

[0052] The above device is used to achieve the following working process: firstly, the water tank that is large in size, thin in thickness and easy to deform is supported from the inside during the hoisting process, so as to avoid the deformation of the tank body; secondly, the stability of the tank body is increased to avoid the shaking of the tank body during the hoisting process; at the same time, the annular end plate 11 is used to tighten the position of the tank mouth by abutting on both sides, so as to further avoid the loosening of the tank body during hoisting.

[0053] Example 2

[0054] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 1, a plurality of tank mouth abutting parts are fixedly assembled and connected on the outer side wall of the annular end plate 11, and the tank mouth abutting parts are used to abut the tank from the side. The tank mouth abutting parts cooperate with the annular end plate 11 to abut the tank mouth from the side, effectively avoiding relative shaking between the tank and the annular end plate 11, which causes the annular end plate 11 to stagger and disengage from the tank mouth.

[0055] Specifically, the tank mouth abutment component comprises a connecting screw 22 fixedly connected to the annular end plate 11 , a abutment plate 21 is slidably connected to the connecting screw 22 ; and a pushing nut is threadedly connected to the abutment plate 21 .

[0056] During operation, the push nut is pushed inward until the clamping plate 21 abuts against the surrounding of the tank body from all directions. This method can keep the mouth of the tank body fully locked and positioned, thereby greatly increasing the stability of the lifting.

[0057] According to the existing method, the top of the above-mentioned annular end plate 11 is fixedly connected with a wire rope fixing ring body 13 (the wire rope fixing ring body is welded with a connecting steel rod, and the connecting steel rod is welded on the annular end plate 11. During operation, the wire rope is fixed to the wire rope fixing ring body 13).

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
