Description

Thread lifting mobile steering wheel

technical field

The utility model relates to a thread lifting moving steering wheel.

Background technique

In the existing equipment that can move easily, most of them take universal wheels as the base. Such devices generally do not have stable placement and are easy to move. And equipment that can be relatively fixed in a certain position after being placed, such as libraries and home bookshelves, fixed stand-alone machines in industrial production lines, etc. Because these objects have a certain quality, it is relatively laborious to move them manually. At present, there are mainly methods:

①. The industrial production line equipment in the production workshop can be moved by crane. The disadvantage is that it is not suitable for micro-movement, and for equipment with a long length and relatively light weight, it is easy to cause uneven force and partial deformation of the equipment.

②. Hydraulic trolleys are widely used in equipment movement, but for occasions such as the movement of household furniture and the overall movement of library bookshelves, it is not suitable to be equipped with hydraulic trolleys because of their relatively large structure and relatively low cost. higher.

③. Carrying small tanks, commonly known as ground cattle, is widely used in handling small and relatively heavy equipment. The disadvantage is that jacking equipment such as jacks is required for combined use, and it is difficult to change the direction during the movement.

Contents of the invention

The utility model aims to solve the problems of difficult direction change and high cost existing in the existing mobile equipment for carrying goods, and provides a threaded lifting mobile steering wheel which is easy to change direction and has low cost.

Technical scheme of the utility model:

The thread lifts and moves the steering wheel, including a rotatable bottom wheel, and the bottom wheel is fixed on the bottom wheel support frame. A stressed connecting rod is installed in the ring, and an upper pressure-bearing ring is embedded in the side groove of the stressed connecting rod, and a thrust ball bearing is placed between the upper pressure-bearing ring and the bottom stressed ring; A main jacking plate is installed on the stressed connecting rod, and the main jacking plate is lifted up and down through bolts and nuts on the main jacking plate.

Further, the upper pressure-bearing ring is composed of two semi-circular rings, with guide holes on them, which are guided in cooperation with the guide rods of the main jacking plate.

Further, a top rubber block is installed on the main lifting board.

Further, the stressed connecting rod is fixed on the support frame of the bottom wheel through an outer clamp spring.

Further, the bottom wheel is fixed on the bottom wheel supporting frame by rivets.

Working principle: Turn the nut with a wrench, the main jacking plate rises (or falls), and the top rubber block firmly (or loosens) the equipment. At this time, the bottom wheel, the bottom wheel support frame, the stressed ring at the bottom, and the lower part of the thrust ball bearing form a partial block to rotate as a whole, while the other partial whole consists of the upper part of the thrust ball bearing, the stressed connecting rod, and the upper part of the bearing. The ring, the main jacking plate and the top rubber block form together. During the movement, the direction is changed by manually turning the lower local block.

The main application occasions of the utility model are: the displacement of the main large-scale furniture in the family; the overall movement of the shelves of the shopping malls and the bookshelves of the library; the moving company, some furniture and freight companies; The overall movement in . And in some special occasions, if the equipment truck cannot be directly transported into the factory entrance or the laboratory entrance due to space constraints, it can be taken off the truck with a hydraulic trolley first. If the space at the entrance cannot meet the simultaneous entry of equipment and hydraulic trolley In this case, the thread lifting mobile steering wheel is undoubtedly the best choice.

Advantage of the utility model:

1. Thread transmission is adopted for lifting, and the sliding screw is easy to realize self-locking, which is safe and reliable during the moving process.

2. The rotation in the direction of the bottom wheel utilizes that the upper and lower parts of the thrust ball bearing can move relative to each other. Because the direction of the ground support force on the bottom wheel and the pressure direction of the equipment on the steering wheel are basically on the same straight line, the radial force on the thrust ball bearing can basically be ignored, and it mainly bears the axial force, which is beneficial to the work of the thrust ball bearing And service life, it can be very convenient to turn during the process of moving equipment.

3. In the process of lifting the equipment, every time the screw rotates one circle, the equipment only rises by one lead distance. Relatively speaking, it is convenient to adjust the consistency of the rising height of each part of the equipment. The equipment is quite stable and reliable during the lifting process.

4. High efficiency, wide application and low cost.
