Technical Field

The utility model relates to a ray protection technical field especially relates to a balanced roller train for bearing concrete door.

Background

The radiation damage refers to the damage of radiation to human body, which can cause damage to hematopoietic organs, digestive system and central nerve, and the concrete door with heavier weight and larger volume is a common radiation protection product in the radiation protection industry.

However, the existing balancing roller set for the load-bearing concrete door has the following problems: due to the weight and the volume, the bearing wheel box of the door body often has the defects of blockage, unsmooth operation, poor contact and the like.

SUMMERY OF THE UTILITY MODEL

An embodiment of the utility model provides a balanced roller train for bearing concrete door to solve because the reason of weight and volume, the technical problem of defects such as card resistance, operation are not smooth, contact are not good often can take place for the bearing wheel case of the door body.

The embodiment of the utility model provides an adopt following technical scheme: the utility model provides a balanced roller train for bearing concrete door, includes gyro wheel base, balancing unit, strutting arrangement, bearing group and roller train, the gyro wheel base is placed on the horizontal plane, balancing unit installs on the gyro wheel base, strutting arrangement passes through balancing unit and is connected with the gyro wheel base, the bearing group is connected with strutting arrangement, the roller train is installed on the bearing group.

Further, the balancing device comprises a balancing shaft, and the balancing shaft is installed on the roller base.

Further, strutting arrangement includes the gyro wheel support, the gyro wheel support is the T type setting on the balance shaft and is connected with the gyro wheel base.

Further, the bearing group comprises two bearings, and the two bearings are symmetrically arranged on the roller bracket.

Further, the roller group comprises two rollers, the two rollers are respectively installed on the two bearings and are rotatably connected with the two bearings, and the two rollers are respectively located on two sides of the balance shaft.

The embodiment of the utility model provides an above-mentioned at least one technical scheme who adopts can reach following beneficial effect:

firstly, the balance shaft is positioned between the two rollers to fill the gap between the two rollers, so that the two rollers are stressed uniformly when being pressed downwards by the door track, and the problem of poor contact between the door track and the roller wheel surface is effectively avoided.

And secondly, the roller support can be adjusted by rotating the balance shaft under the action of gravity and rail pressure, so that the upper surfaces of the two rollers can be in good contact with the surface of the rail of the door body all the time.

In the drawings:

fig. 1 is a front view of the present invention;

fig. 2 is a cross-sectional view of the present invention.

Reference numerals

The roller support comprises a roller base 1, a balancing device 2, a balancing shaft 21, a supporting device 3, a roller bracket 31, a bearing group 4, a bearing 41, a roller group 5 and a roller 51.

Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1-2, the embodiment of the utility model provides a balanced roller train for bearing concrete door, including roller base 1, balancing unit 2, strutting arrangement 3, bearing group 4 and roller train 5, roller base 1 places on the horizontal plane, balancing unit 2 installs on roller base 1, strutting arrangement 3 is connected with roller base 1 through balancing unit 2, bearing group 4 is connected with strutting arrangement 3, roller train 5 installs on bearing group 4.

Preferably, the balancing device 2 comprises a balancing shaft 21, and the balancing shaft 21 is mounted on the roller base 1; the balance shaft 21 is positioned between the two rollers 51 to make up the gap between the two rollers 51, so that the two rollers 51 are stressed uniformly when being pressed downwards by the door body track, and the problem of poor contact between the door body track and the roller 51 wheel surface is effectively avoided.

Preferably, the supporting device 3 includes a roller bracket 31, and the roller bracket 31 is arranged on the balance shaft 21 in a T shape and connected with the roller base 1; the roller bracket 31 can be adjusted by the rotation of the balance shaft 21 under the action of gravity and rail pressure, so that the upper surfaces of the two rollers 51 can be in good contact with the surface of the door rail all the time.

Preferably, the bearing set 4 includes two bearings 41, and the two bearings 41 are symmetrically installed on the roller bracket 31; the two bearings 41 allow the two rollers 51 to roll and can withstand heavy and impact loads.

Preferably, the roller set 5 includes two rollers 51, the two rollers 51 are respectively installed on the two bearings 41 and rotatably connected with the two bearings 41, and the two rollers 51 are respectively located at two sides of the balance shaft 21; the two rollers 51 are used for supporting the door body rail.
