technical field

The utility model relates to the technical field of roller stands, in particular to an electric maintenance roller stand.

Background technique

In the known technical field, iron cores are widely used in products such as motors and transformers. However, welding operations are required during the production of the iron core. After the welding operation, the iron core needs to be inspected and repaired, and the conditions such as weld seams and welding slag in the iron core are checked and repaired. Because some iron core products are bulky and heavy, it is very inconvenient to check. Usually, maintenance personnel hoist the iron core, place it vertically on the ground, and one end of the hollow hole of the iron core is in contact with the ground, and then the maintenance personnel check the inside of the iron core with the help of a light source such as a flashlight. It is not only laborious and time-consuming to overhaul, but sometimes it is necessary to use a riser to stand on it and overlook the inside of the iron core. And because the hollow hole of the iron core fits the ground, the light inside the iron core is weak, which is very unfavorable for the carrying out of maintenance work. In addition, one end of the iron core is attached to the ground, and the inspection of the end near the ground is due to the light, the sight of the inspector, etc., resulting in insufficient inspection and maintenance, and it is easy to miss inspection or repair and produce defective products.

The iron core can lie flat on the fixed base through the rotating roller device, so that the two ends of the iron core are transparent, and the light required for maintenance can enter the iron core sufficiently. core inside. And through the deceleration motor drives the chain transmission mechanism to drive the rotating roller device to rotate, so as to drive the iron core to be inspected to rotate. The iron core can be rotated at a constant speed or jogged according to the needs, which is convenient for the maintenance personnel to inspect the inside and outside of the iron core from various directions and positions. Quality problems such as existing welding slag or unqualified weld seams, without having to move the iron core again. Moreover, the top-rising adjustment mechanism is used to adjust the tightness of the chain transmission mechanism, which is applicable to iron cores of different weights.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1-3, the preferred embodiment of the present utility model is an electric maintenance roller frame, which includes a rectangular fixed base 1, a deceleration motor 2 is arranged on one side of the rectangular fixed base 1, and the deceleration motor 2 is connected with a deceleration motor The chain transmission mechanism 3 driven by the motor 2 is provided with several groups of rotating roller devices 4 driven by the chain transmission mechanism 3 on the rectangular fixed base 1, and it is useful to install on the rectangular fixed base 1 and on the side adjacent to the gear motor 2 The top-up adjustment mechanism 5 for adjusting the tension of the chain transmission mechanism 3 is located between two adjacent sets of rotating roller devices 4 .

The rotating roller device 4 includes several first bearing seats 6 arranged on the rectangular fixed base 1 and adjacent to the reduction motor 2, and the rectangular fixed base 1 is provided with a number of second bearing seats 6 in one-to-one correspondence with the first bearing seats 6. The bearing housing 7, the first bearing housing 6 and the second bearing housing 7 are provided with a roller 8.

The chain transmission mechanism 3 has a first gear 9 installed on the reduction motor 2 , several second gears 9 arranged outside the first bearing housing 6 and coaxially connected with the roller 8 , and a transmission chain 11 .

The top-rising adjustment mechanism 5 comprises an L-shaped support 12 arranged on the rectangular fixed base 1, a chute 13 is vertically arranged in the L-shaped support 12, and a slide block 14 that can slide up and down along the chute 13 is provided in the chute. The top of the slide block 14 is provided with an adjustment screw rod 15, the adjustment screw rod 15 extends upwards and passes through the top of the L-shaped bracket 12, the slide block 14 is also pinned with an adjustment gear 10, and the adjustment gear 10 and the transmission chain 11 Drive connection.

Both ends of the roller 8 are provided with annular sleeves 18 for carrying anti-collision hoops 17, and the anti-collision hoops 17 rest on the annular sleeves 18 to prevent the roller 8 from damaging the iron core due to friction when rotating. And the annular sleeve 18 can raise the iron core, so that there is a gap between the iron core and the roller 8, which reduces friction and facilitates hoisting.

During use, as shown in Figure 3, two anti-collision hoops 17 for hoisting and protecting the iron core are fixed on the outside of the iron core, and then hoisted onto the utility model electric maintenance roller frame, so that the iron core and the roller 8 Place in parallel, place the hoop on the ring sleeve 18. Then start the reduction motor 2, the reduction motor 2 drives the first gear 9 in the chain transmission mechanism 3 to rotate, the first gear 9 drives the second gear 10 and the adjustment gear 11 to rotate through the transmission chain 12, and the second gear 10 drives two rollers 8 rotate synchronously, the roller 8 and the anti-collision hoop 17 on the iron core generate friction, and then drive the iron core to rotate slowly, so that the quality inspectors can perform quality inspection on the inside and outside of the iron core at both ends of the iron core And maintenance, no need to lift the iron core. And because the iron core is placed horizontally, light enters the openings at both ends, which can improve the accuracy of quality inspection and maintenance of maintenance personnel, and does not require maintenance personnel to change positions around the iron core for inspection, reducing the workload of quality inspection personnel . Both ends of the iron core can be inspected, which improves the accuracy of inspection. When the tightness of the transmission chain 12 needs to be adjusted according to factors such as iron core weight, the screw mandrel 16 in the top adjustment mechanism 5 is rotated, the screw mandrel 16 drives the slide block 15 to slide up and down, and the slide block 15 drives the adjustment gear 11 to move up and down. When the third gear 10 moves upwards, it tightens the transmission chain 12, making the transmission chain 12 tight; when the adjusting gear 11 moves downwards, the transmission chain 12 is loosened a little. A baffle plate can also be provided on the outside of the chain drive mechanism 3, which makes the operation of this mechanism safer. The reduction motor 2 can move forward and reverse at a constant speed, and can also operate forward and reverse in jog according to needs.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
