Abstract
The utility model relates to an adjustable device of a tower scaffold, which mainly comprises an adjustable footstock part and an adjustable base part that are fixed on a standard pipe frame. In the two parts, the rolling friction is utilized to replace the original rolling friction, so the friction force is greatly lightened, and the height is easily and freely adjusted by rotating a handle. Compared with the prior art, the utility model has the advantages of small friction force and easy and free rotation. The adjustable footstock part and the adjustable base part use common parts which comprise a shaft block, a thrust bearing and a bearing cap, so as to cause the variety of the parts to be reduced, and be convenient for manufacture and management.
Description
Technical field
The utility model relates to a kind of builing industry scaffold, particularly relates to the tunable arrangement of squarer formula scaffold.
Background technology
The early stage scaffold that uses all uses steel pipe and fastener to set up basically, reports often, and the scaffold that collude owing to the steel button takes off, reasons such as steel pipe fracture, steel pipe press-bending causes collapses, and causes casualties.In recent years, squarer formula scaffold comes out, and is excellent rigidity really, takes and tear convenience, safe in utilization open.But when scaffold was higher, the pressure that adjustable base and adjustable jacking bear was very big, watered particularly that to have smash ten parts of concrete mould bases heavy, when building and dismantling squarer formula scaffold, all needed to increase and fell the support height.The handle of moving adjustable base of plate and adjustable jacking is very hard, wants to increase the arm of force with steel pipe socket on handle, usually because objects such as standard pipe support on every side block, and is difficult to put to good use.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, provide a kind of rotation easily, big, easy to use, the long-lived squarer formula of bearing capacity scaffold tunable arrangement.
For achieving the above object, the technical solution of the utility model is: the tunable arrangement of this squarer formula scaffold mainly comprises the adjustable footstock parts and the adjustable base parts that are fixed on the standard pipe support.
The utility model relates to tunable arrangement wherein, comprises adjustable footstock parts and adjustable base parts.In these two kinds of parts, replace sliding friction in the past with rolling friction, alleviated frictional force greatly, regulate highly becoming free and relaxed with swing handle.
The utility model is compared with prior art and is had the following advantages:
1. frictional force is little, rotates free and relaxed.
2. adjustable footstock parts and adjustable base parts have used universal component, comprise bearing support, thrust bearing, bearing cover, make the part kind reduce, and are convenient to make and management.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1 and Figure 2, squarer formula scaffold is by adjustable footstock parts 1, standard pipe support 2, and pitman 3, adjustable base parts 4 constitute.
Four steel pipe sockets of bottom standard pipe support 2 are connected on four adjustable base screw mandrels 4-1, and pressure-bearing is on bearing cover 1-2.
The standard pipe support 2 of upper and lower layer is located by pitman 4 and is connected, and the two ends of pitman 4 are all porose, also have with the hole of diameter corresponding on the cooperation position of standard pipe support 2.About inserting, pitman in the steel pipe of two layers of standard pipe support 2, can in corresponding aperture, inserting bolt be fixed together pitman 4 and standard pipe support 2.Standard pipe support 2 is can multilayer overlapping, also can rely on cross support 3 laterally to connect to be combined into a sheet of, is provided with flexibly according to the construction needs.
Inserted adjustable footstock screw mandrel 1-1 in the steel pipe of the standard pipe support 2 of the superiors, bearing cover 1-4 pressure-bearings are on steel pipe.
As shown in Figure 3, Figure 4, adjustable base parts 4 are by trapezoidal screw 4-1, bearing support 1-2, thrust bearing 1-3, and bearing cover 1-4 constitutes, and under the constraint of adjustable base screw mandrel 4-1, vertically links together along same axis heart line.The endoporus of bearing support 12 has trapezoidal thread and screw mandrel to be complementary, and during handle on the impeller-hub bearing 1-2 1-2-1, bearing support 1-2 rotations make bearing cover 1-4 rise or descend, and are supported on standard pipe support 2 lifting thereupon on the bearing cover 1-4.The construction that acts on of adjustable base parts 4 is the levelness of regulating the concrete mould bases in earlier stage, is the heavy pressure that scaffold is broken away from the concrete mould bases in the construction later stage.Because the upper strata load is bigger, so all be provided with a thrust bearing on the lifters of each adjustable base, replaces sliding friction with rolling friction, make that rotatablely moving of lifters still can be free and relaxed under big heavy burden.
As shown in Figure 5; there is the cavity that holds thrust bearing the lower surface of bearing cover 1-4; middle porose sky is enclosed within on the screw mandrel; there are 10-20 gradients of spending the upper surface that the utility model is provided with bearing cover 1-4 especially; shape such as umbrella push up, and its effect also is in order to prevent that rainwater from entering bearing support, because there is the steel pipe of standard pipe support 2 to cover the hole of bearing cover 1-4 centres really; can under the oblique top surface current of bearing cover 1-4, can reach the protection purpose as long as guarantee rainwater.
As Fig. 6, shown in Figure 7, adjustable footstock parts 1 are made up of screw mandrel 1-1, bearing support 1-2, thrust bearing 1-3 and bearing cover 1-4.Be similar to adjustable base is turned around placement.In the practice of construction, these two also can replaced really and use, but the professional inadequately point of function.For the ease of management, adjustable footstock parts have used general purpose accessory: bearing support 1-2, thrust bearing 1-3 and bearing cover 1-4, can reduce the part kind like this, and be convenient to make and management.
The utility model is simple in structure, and is easily manufactured, easy and flexible operation.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
