Description

A counter force loading frame whose loading height can be automatically adjusted

technical field

The utility model relates to a counter force loading rack, in particular to a counter force loading rack whose loading height can be automatically adjusted.

Background technique

The currently known counter force loading frame is mainly composed of fixed columns and adjustable beams. The installation height of the beam determines the loading height of the anti loading frame, and the height of the beam can be adjusted. The usual way is to hoist the crossbeam to the corresponding position by lifting equipment such as driving or crane. This adjustment method is time-consuming and laborious, the operation is difficult, and it is very unsafe.

Utility model content

The purpose of the utility model is to provide a reaction force loading frame whose loading height can be automatically adjusted. The reaction force loading frame can not only automatically adjust the loading height, but also save costs, improve adjustment efficiency, and is safe and reliable.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A reaction force loading frame whose loading height can be automatically adjusted, including the bolts of the fixed part of the reaction force frame, and a height-adjustable crossbeam, which is fixedly connected with the fixed part of the reaction force frame through a movable connection structure, and the two ends of the height-adjustable crossbeam A motor-worm gear-lifting screw structure is respectively provided. The installation height of the height-adjustable beam determines the loading height of the counter force loading frame.

Further, the motor and the worm gear are connected together and fixed together on the top of the reaction frame.

One end of the lifting screw is fixed on the end of the height-adjustable beam, and the other end is connected together with the worm gear.

The movable connection structure is a bolt screw hole connection.

There are two groups of motor-worm gear-lifting screw structures.

When it is necessary to adjust the loading height, loosen and remove the multiple fixing bolts connecting the height-adjustable beam and the fixed part of the reaction frame, start the motor, and the motor drives the worm gear to rotate, and the lifting screw that cooperates with the worm gear will drive the adjustable The crossbeam moves up and down. When it is adjusted to a suitable loading height, the motor stops rotating, and the worm wheel driven by the motor also stops rotating. The adjustable crossbeam also stops moving in the direction of the lifting screw axis. At this time, re-insert the fixing bolts and tighten them to load. Height adjustment is complete.

Owing to adopting said scheme, the beneficial effect of the utility model is:

The loading height of the loading reaction frame can be automatically adjusted without the need for lifting equipment or the cooperation of multiple people, which improves the adjustment efficiency, and the whole process is safe and reliable.

Description of drawings

Fig. 1 is a structural schematic diagram of a counter force loading frame with automatic adjustment of loading height.

The numerals in it illustrate: 1. One fixed column of the reaction frame; 2. Two fixed columns of the reaction frame; 3. Three fixed columns of the reaction frame; 4. Four fixed columns of the reaction frame; 5. Height adjustable beam; Screw rod; 8 worm gear; 9 reaction force frame top plate; 10 motor.

Detailed ways

The utility model is described in further detail below in conjunction with the embodiment shown in the accompanying drawings.

As shown in Figure 1, the utility model discloses a counterforce loading frame whose loading height can be automatically adjusted, which includes fixing columns 1, 2, 3 and 4, each of which is provided with screw holes; Screw holes are also arranged at both ends of the adjusting beam, and the height-adjustable beam 5 is installed together with the columns 1, 2, 3, and 4 through fixing bolts 6.

The motor 10 is connected with the worm gear 8 and is jointly fixed on the top plate of the reaction force frame; one end of the lifting screw 7 is fixed on the height-adjustable crossbeam 5 , and one end is matched and connected with the worm gear 8 .

There are two sets of motor-worm gear-lifting screw structures, which are respectively located at the two ends of the height-adjustable beam.

When adjusting the loading height of the reaction force loading frame, first loosen and take off some fixing bolts 6 connecting the height-adjustable beam 5 and the reaction force frame fixing columns 1, 2, 3, 4, and then start the motor 10 (and other groups of motors ), the motor-driven worm gear 8 (and other groups of worm gears) starts to rotate, drives the lifting screw mandrel 7 to move up and down, and the lifting screw mandrel 7 drives the height-adjustable beam 5 to move up and down. When reaching the appropriate position, stop the motor 10 (and other groups of motors), re-insert the fixing bolts 6 into the corresponding screw holes of each fixing column and the height-adjustable crossbeam 5 and tighten the fixing bolts, the height-adjustable crossbeam 5 It can be fixed at the new height.

The counter force loading rack shown in the utility model can not only automatically adjust the loading height, but also save time and labor, and is safe and reliable.

The above description of the embodiments is for those of ordinary skill in the technical field to understand and apply the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described here to other embodiments without creative efforts. Therefore, the utility model is not limited to the embodiments here, and improvements and modifications made by those skilled in the art according to the disclosure of the utility model without departing from the scope of the utility model should be within the protection scope of the utility model.
