Description

Technical Field

[0001] The utility model relates to the field of scaffolding bases, in particular to an adjustable scaffolding base. Background Art

[0002] Scaffolding is often used in construction work. Scaffolding is a kind of construction tool temporarily set up for workers. It is mainly set up to solve the problems of high places and horizontal transportation. Scaffolding base is often used in the process of installation and use. The scaffolding base is mainly used to adjust the scaffolding to keep the scaffolding stable. An adjustable scaffolding base mainly consists of a base plate, a screw fixed on the base plate and a sleeve rotatably sleeved on the screw to support the bearing tube. In actual use, it is necessary to rotate the sleeve to achieve the effect of the sleeve moving on the screw and thus achieving the effect of the bearing tube being lifted up or moved down. Since the sleeve is on the screw while rotating and moving, the relative state between it and the bearing tube is always rotating. Since the scaffolding is large and high, the weight of the bearing tube and the other components thereon makes the friction between it and the sleeve abutting surface is large. The sleeve is more laborious when rotating and is also easy to cause wear to the sleeve abutting surface, which accelerates the aging of the sleeve. Summary of the invention

[0003] The technical problem to be solved by the utility model is as follows: in actual use, it is necessary to rotate the sleeve to achieve the effect of moving the sleeve on the screw rod and thus achieving the effect of lifting or moving the supporting tube. Since the sleeve is on the screw rod and moves while rotating, the relative state between it and the supporting tube is always rotating. Since the scaffold is erected larger and higher, the weight of the supporting tube and the remaining components thereon makes the friction between it and the sleeve abutment surface larger. The sleeve is more laborious when rotating and is also prone to cause wear to the sleeve abutment surface, which accelerates the aging of the sleeve.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: an adjustable scaffolding base, including a base plate, a screw fixed on the top surface of the base plate and a sleeve rotatably sleeved outside the screw, two rotating blocks are symmetrically arranged outside the sleeve, the sleeve is a cylindrical structure with an H-shaped cross-section, and an auxiliary part for reducing the friction between the sleeve and the external scaffolding bearing tube is clamped inside the top surface of the sleeve.

[0005] The beneficial effects of the utility model are as follows: the auxiliary part clamped on the top surface of the sleeve is used to reduce the wear between the top surface of the sleeve and the bearing tube, thereby increasing the service life of the sleeve; at the same time, the replaceable auxiliary part further increases the service life of the entire scaffolding base.

[0006] As a further improvement of the present invention, the technical problem to be solved is: what specific structure of the auxiliary component can reduce the wear between the top surface of the sleeve and the external load-bearing tube.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the auxiliary part includes two pads symmetrically clamped in the top of the sleeve, the pads are semi-circular block structures, and the top surface of the pads is embedded with a plurality of sliding balls abutting against the scaffolding bearing tube, and the bottom of the sleeve is provided with an ejector for ejecting the sleeve.

[0008] The beneficial effects of the above improvement are as follows: two semi-circular ring block structure gaskets can be assembled into a full circular ring block structure to separate the top surface of the sleeve from the bottom end of the external supporting tube, and the thickness of the gasket is smaller than the inner height of the sleeve top, which will not affect the abutment effect on the receiving tube, and the sliding ball is used to reduce the friction between the external supporting tube and the top surface of the gasket, thereby achieving the effect of increasing the service life of the sleeve.

[0009] The utility model further improves the technical solution adopted as follows: the ejector includes two ejector rods vertically inserted in the sleeve for lifting the corresponding pad blocks, a connecting semi-ring is connected between the bottom ends of the two ejector rods, the connecting semi-ring is concentrically arranged with the sleeve, and two limiting rods penetrating to the top surface of the rotating block are symmetrically arranged on the top surface of the connecting semi-ring, and the limiting rod is a rod body structure with a larger upper portion and a smaller lower portion.

[0010] The beneficial effects of the above improvements are as follows: the push rod can be used to push the pad out of the sleeve, which is convenient for replacing the pad with severe wear. The cooperation of the connecting half ring and the limit rod can facilitate the connection of the two push rods together and limit them on the sleeve, thereby realizing the connection between the push rod and the sleeve.

[0011] The utility model further improves the technical solution adopted as follows: a plug-in half ring is protruding from the bottom surface of the cushion block, and a plug-in ring groove cooperating with the plug-in half ring is opened on the top surface of the sleeve.

[0012] The beneficial effect of the above improvement is that the two cushion blocks and the sleeve can be relatively fixed together by utilizing the cooperation between the plug-in half ring and the plug-in ring groove.

[0013] The utility model further improves the technical solution adopted as follows: a ejection hole which cooperates with the connecting half ring and is communicated with the plug-in ring groove is vertically opened in the sleeve.

[0014] The beneficial effect of the above improvement is that it is easy for the ejector rod to move in the ejection hole to achieve the effect of lifting the cushion block. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-3 As shown, an adjustable scaffolding base includes a base plate 1, a screw 2 fixed on the top surface of the base plate 1, and a sleeve 3 rotatably sleeved on the outside of the screw 2. Two rotating blocks 4 are symmetrically arranged outside the sleeve 3. The sleeve 3 is a cylindrical structure with an H-shaped cross section. An auxiliary part for reducing the friction between the sleeve 3 and the external scaffolding bearing tube is clamped inside the top surface of the sleeve 3. The auxiliary part clamped on the top surface of the sleeve 3 is used to reduce the wear between the top surface of the sleeve 3 and the bearing tube, thereby improving the service life of the sleeve 3; at the same time, the replaceable auxiliary part further improves the service life of the entire scaffolding base. Example

[0021] The technical solution is basically the same as that of the first embodiment, except that Figure 1-3 As shown, the auxiliary parts include two cushion blocks 5 symmetrically clamped in the top of the sleeve 3. The cushion blocks 5 are semicircular block structures. A plurality of sliding balls 9 abutting against the scaffolding bearing tube are embedded in the top surface of the cushion blocks 5. The bottom of the sleeve 3 is provided with an ejector for ejecting the sleeve 3. The ejector includes two ejector rods 7 vertically inserted in the sleeve 3 for jacking up the corresponding cushion blocks 5. A connecting semi-ring 6 is connected between the bottom ends of the two ejector rods 7. The connecting semi-ring 6 is concentrically arranged with the sleeve 3. Two limit rods 8 penetrating to the top surface of the rotating block 4 are symmetrically arranged on the top surface of the connecting semi-ring 6, and the limit rods 8 are a rod structure with a larger upper part and a smaller lower part. The pads 5 of two semicircular ring block structures can be assembled into a full circular ring block structure, separating the top surface of the sleeve 3 from the bottom end of the external bearing tube, and the thickness of the pads 5 is less than the inner height of the top of the sleeve 3, which will not affect the abutment effect on the receiving tube. Compared with the full circular ring block structure, the pads 5 of the semicircular ring block structure can be directly placed in the top surface of the sleeve 3 without being pushed out from the screw 2, and the friction between the external bearing tube and the top surface of the pads 5 is reduced by the sliding ball 9, so as to achieve the effect of increasing the service life of the sleeve 3. The pads 5 can be pushed out of the sleeve 3 by the push rod 7, which is convenient for replacing the pads 5 with large wear. The cooperation of the connecting half ring 6 and the limiting rod 8 is convenient for connecting the two push rods 7 together and limiting them on the sleeve 3, so as to realize the connection between the push rod 7 and the sleeve 3. Example
