Description

Standard knot main chord transfer frame

Technical Field

The utility model relates to a tower crane technical field, concretely relates to mark festival main chord processing transports frame.

Background

In the field production process, the mode of single-support hoisting and frame loading is generally adopted in the production and the transfer of the main chord of the standard knot, the mode can form scars on the surface of a workpiece, potential safety hazards exist, the labor capacity can be increased, the production efficiency is reduced, and the follow-up assembly is difficult to meet the assembly requirements of the same group for the same group machining.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mark festival main chord processing transport frame to solve main chord processing and transport the problem of inefficiency.

In order to achieve the purpose, the mark joint main chord transfer frame comprises a bottom frame, support legs and a support positioning device, wherein the bottom frame is a rectangular frame and comprises cross beams and longitudinal beams, the support legs are fixedly arranged at the lower parts of four corners of the bottom frame, a plurality of groups of positioning blocks are arranged on the cross beams, and two positioning blocks are one group and used for limiting the main chord; the upper parts of the four corners of the underframe are provided with support leg positioning devices; lifting lugs are arranged on the sides of the four corners of the bottom frame.

Furthermore, the supporting foot positioning device is composed of two positioning plates which are arranged at a right angle.

Further, the support positioning device is a groove.

Further, the positioning blocks comprise an inclined surface, and the two inclined surfaces of the two positioning blocks form a V-shaped area for placing the main string.

Further, a bottom beam is arranged between the two cross beams.

Further, a stiffening beam is arranged between the two leg positioning means.

The utility model has the advantages that: the main strings are placed on the bottom frame through the positioning blocks, then the lifting lugs on the bottom frame are lifted to the processing area, the main strings are separated from the transfer frame in the processing area, and the transfer frame is dragged to the main strings and then transferred to the finished product area through the lifting lugs.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1, a mark section main chord transfer frame comprises an underframe, support legs 3 and support leg positioning devices 6, wherein the underframe is a rectangular frame and comprises cross beams 1 and longitudinal beams 2, the support legs 3 are fixedly arranged at the lower parts of four corners of the underframe, a plurality of groups of positioning blocks 4 are arranged on the cross beams 1, and two positioning blocks 4 are in one group and used for limiting a main chord 9; the support leg positioning device 6 is fixedly arranged on the upper parts of the four corners of the bottom frame, and lifting lugs 5 are arranged on the sides of the four corners of the bottom frame. Wherein, the supporting leg positioning device 6 is provided with two positioning plates which are arranged at a right angle and are positioned at the outer side. The foot positioning means 6 may also be grooves. Both structures can ensure that the support legs on the other transfer frame are correctly placed. The positioning blocks 4 comprise an inclined plane, and the two inclined planes of the two positioning blocks 4 form a V-shaped area for placing the main string 9. The locating piece can be cut by the steel block, also can be cut by square pipe, saves the cost.

A bottom beam 7 is arranged between the two cross beams 1 and a stiffening beam 8 is arranged between the two foot positioning means 6. The bottom beams 7 and the reinforcing beams 8 are used for further reinforcing the underframe. The stabilizer blade 3 is that two boards are the right angle setting, and its effect is used for carrying out the stabilizer blade when the frame stacks and counterpoint.

Fig. 2 is a schematic view of the placement of the main chord 9 on the transport rack, from which it can be seen that the length of the main chord 9 is greater than the length of the longitudinal beam 2. After the main strings are placed on the underframe, the transfer frame is hoisted through the lifting lugs 5 on the underframe and is transported to a processing area, so that 4 main strings can be transported at one time, the working efficiency is improved compared with that of single transportation, the main strings cannot be damaged, after the transfer frame reaches the processing area, an equipment table (not shown in the figure) is arranged on the processing area, a fixed groove is arranged on the equipment table, the transfer frame falls into the fixed groove, and the main strings 9 are erected on two sides of the fixed groove due to the fact that the main strings are long in length, and therefore the transfer frame is separated from the fixed groove. During the processing procedure of the main strings, the positions of the main strings are kept unchanged. After the main strings are processed, the transfer frame is lifted, the main strings fall on the positioning blocks 4 and are placed in a finished product area along with the transfer frame. As shown in fig. 3, the support leg positioning device 6 is arranged on the transport rack, so that the support legs of the transport rack can be easily and stably placed on the support legs of another transport rack, stacking of a plurality of transport racks is realized, and the main strings 9 are placed regularly.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
