Description

A step-by-step lifting load-carrying platform

technical field

The utility model relates to the field of machinery, in particular to a step-by-step lifting load-carrying platform.

Background technique

In the construction process of hydraulic structures, in order to improve the overall anti-permeability of the building, it is often necessary to perforate and grout, and the grouting holes are usually evenly arranged in the height direction, so a load-bearing platform that can provide different heights is required for Install drilling and grouting equipment. Under normal circumstances, the whole house scaffolding scheme is adopted. When using this scheme, as the position of the grouting hole increases, the height of the bent frame must be increased accordingly. The process is complicated, the consumption of steel is large, and the cost is high.

Contents of the invention

The problem to be solved by the utility model is to provide a step-by-step lifting and lowering load-carrying platform with simple structure, low manufacturing cost, convenient operation and high safety and stability, aiming at the deficiencies in the prior art.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A step-by-step lifting load-bearing platform, including a load-bearing platform, four columns and four jacking cylinders. The load-bearing platform is a rectangular frame structure with pin holes at its four corners, and the pin holes are evenly distributed along the straight line. The clamping position on the column is hinged, and the four jacking cylinders are end-jointed hydraulic cylinders. The bottom of the jacking cylinder is hinged to the clamping position on the column through the installation ear plate, and the top of the jacking cylinder is connected to the load-bearing platform respectively. The four corners are connected.

The hinges are bolt hinged.

The jacking stroke of the jacking cylinder is greater than the distance between the two sets of clamping positions on the column.

The utility model provides a step-by-step lifting load-bearing platform, which can realize the step-by-step lifting of the load-bearing platform by using a single-stage jacking cylinder. The structure is simple, the manufacturing cost is low, and the operation is convenient. The load on the platform has high overall safety and stability, and has certain promotional value.

Detailed ways

As shown in Figures 1 to 4, a step-by-step lifting load-bearing platform includes a load-bearing platform 2, four columns 1 and four jacking cylinders 3, the load-bearing platform 2 is a rectangular frame structure, and its four corners are There are pin holes 2-1, which can be hinged with the card positions 1-1 evenly distributed on the column 1 along a straight line. The four jacking cylinders 3 are all end-hinged hydraulic cylinders, and the bottom can be installed through the ear plate 3 -1 is hinged with the card position 1-1 on the column 1, and the top is respectively connected with the four corners of the load-bearing platform 2.

In a preferred solution, all the hinges are hinged by the bolt 4 .

In a preferred solution, the jacking stroke of the jacking cylinder 3 must be greater than the distance between the two sets of clamping positions 1-1 on the column 1 .

The working principle of the present utility model is as shown in Figures 5 to 9:

When the utility model is under construction, the bottom of the jacking cylinder 3 is hinged to the column 2 through the installation ear plate 3-1, and the top supports the load-bearing platform 1, and the load-bearing platform 1 itself is also hinged to the column 2 at this time. The lifting cylinder 3 bears the load on the load-bearing platform 1 at the same time, and the overall safety and stability are high, as shown in FIG. 5 .

During the climbing process of the utility model, first disengage the hinge pin 4 between the load-bearing platform 1 and the column 2, and then open the four jacking cylinders 3 synchronously, so that the jacking cylinders 3 are stretched out to withstand the load-bearing platform 1 and rise together. As shown in Figure 6; when the load-bearing platform 1 rises to the previous station, use the latch 4 to hinge the load-bearing platform 1 and the column 2 again, as shown in Figure 7; then disengage the oil cylinder to install the lug 3-1 and the column 2 hinge pin 4 between them, and then synchronously open the four jacking cylinders 3 to retract the jacking cylinders 3. Since the top of the cylinder is fixed, the bottom of the cylinder and the mounting lug 3-1 rise, as shown in Figure 8; when the cylinder When the bottom and the installation ear plate 3-1 are raised to the previous station, the installation ear plate 3-1 and the column 2 are hinged again with the pin 4, as shown in Figure 9; the load-bearing platform 1 and the jacking cylinder 3 climb up to one station Finish. Repeat the steps in Figure 6 to Figure 9 to realize the step-by-step climbing function of the utility model; if the steps in Figure 9 to Figure 6 are performed in reverse, the step-by-step descending function of the utility model can be realized.

The utility model provides a step-by-step lifting load-bearing platform, which can realize the step-by-step lift of the load-bearing platform 1 by using a single-stage jacking cylinder 3. The structure is simple, the manufacturing cost is low, and the operation is convenient. 3 bear the load on the load-bearing platform 1 at the same time, the overall safety and stability are high, and it has a certain promotion value.

Above-mentioned embodiment is only the preferred technical scheme of the present utility model, and should not be considered as the restriction to the present utility model, and the protection scope of the present utility model should be the technical solution described in the claims, including the technology in the technical solution described in the claims. An equivalent alternative to the feature is the scope of protection. That is, equivalent replacement and improvement within this scope are also within the protection scope of the present utility model.
